Water Collection System: Because You Care Anna Grychowski, Chris Petteys, Jacob Feiock, Gavyn Hansotte, Nate Schneider, and Ryan Osche
Abstract Because you care is a non-profit animal shelter that was founded in 1983. Located within the city of Erie, Because you Care is an organization that focuses on the rescue, rehabilitation, and foster care of cats and dogs that go stay within the area. The people that run Because you Care have decided that they would like a system that collects rainwater from around the property and stores it in a centralized reservoir for a memorial garden. Our goal as the freshman SEECS group is to create a collection system that is easy to use as well as being durable enough to withstand the rough Erie climate. To start, we visited the Because you Care location and met with their core leadership group. They toured us around the property and gave us a set of wants for a water collection system that would be built just outside the main building in an area that they want to use as a memorial garden. As of now our group is in the design phase of our project. Taking into consideration every single detail, asking ourselves what can go wrong and what we need to do to prevent things is our main process right now in order to deliver the best end product we possibly can.

Our Design Plan The water collection system will be placed on a 10'x5'x4' concrete slab. The water will be collected from the dog shelter gutters through pipes. Two 275-gallon tanks will collect the water. They will be connected at the bottom through the original tank outlets. There will be a filtration unit before the water enters the tanks that will weed out any major blockage pieces. A pump will be included to increase pressure. A hose and sprinkler system will be installed to aid in watering the memorial garden. A rough image of the design is shown below.
Estimated Timeline

Title: Freshman SEECS Project: Water Collection Unit at Because You Care Abstract: Because You Care is a local non-profit animal rescue and fostering organization. The goal of our project is to engineer a system that collects, stores, and distributes rainwater for the client’s memorial garden. The shelter has had a difficult time collecting enough water to keep up with normal activities let alone enough to maintain a garden. The SEECS freshmen group has started on the design plan, which takes cost, safety, and durability into account. We estimated the water needs for the garden, calculated the tank size accordingly, along with the prices of possible pumps to always ensure adequate waterflow. The preliminary design includes two 275-gallon tanks for rainwater collection. They will be connected by a pipe at the bottom and have upstream filtration to weed out major blockages. The budget for the project is around $1000.00 and we plan to complete the project in the fall of 2023.

Metanoia Retreat A Home Away From Home Preparation and Formation
2 RETREATS
1. Leader formation – TRUST THE PROCESS
REFLECTION:
An 8 week long process that prepares former Metanoia participants to switch roles and take on the responsibilities of leading the retreat. The student leaders seek to become a resource to the retreatants, serving as small group leaders and prayer leaders.
Metanoia is a great opportunity to take a weekend away in order to step out of the hectic college schedule. We try to provide a safe space for students to explore their personal lives and spirituality through both self and group reflection.
Servant leadership! The goal is to put aside personal expectations in order to build a retreat experience that best serves the participants. Leaders are encouraged to be creative in the planning process to facilitate a unique experience, rather than attempt to duplicate their own retreat. 1/2 day retreat: Community building within the team is important to the process. This time includes team building activities, sharing a meal, an in-depth examination of the underlying philosophy and theology of the retreat framework, and of course, prayer.
4 STAFF ACCOMPANIERS
Student leaders invite participants to reflect upon important themes of student/daily life by sharing their own stories. Students are able to apply these themes to their own lives through small group discussion and individual reflection.

Title: Metanoia Retreat: A Home Away From Home Abstract: Metanoia is a student-led, weekend retreat offered through Campus Ministry that brings together a diverse group of Gannon students. Throughout the weekend, leaders presented talks and facilitated small group reflections that encouraged retreatants to take a deeper look at their lives within the context of faith and spirituality. Metanoia means “change of heart.” Metanoia “alumni” are able to live out that “change of heart” through regular, intentional engagement known as “LT4”. Students are welcomed into a new loving, intentional “LT4” family on campus. They also wish to share the good news that “it is April 22nd and you are so loved!” Presenter(s): Cameron Swantek, Bridget Marks, Dale Hyland Sponsoring Department: Campus Ministry Project Mentor: Emily Muntean

Abstract Dementia patients lack digital resources that help them retain memories of their family members and friends. Our objective is to give these patients a resource they can use in collaboration with their family members and friends to create questionnaires with personalized information and images.
Admin or Family and Friend
Our web application features an account system with three distinct types of accounts: patients, family members and friends, and admins. The administrator can begin by creating patients and adding family members to the patient’s account. The family members can then send their personalized questions to the patient. The patient can fill out the questionnaire whenever they like and afterward will be shown the results.
Admin

Family or Friend
The Remember app is geared toward problems found in many older patients. We believe our app will be secure and userfriendly, but, most importantly, we believe it will help dementia patients to retain the quality of life they had prior to dementia.
Introduction Our Senior Design Project is called Remember, it’s a resource for Dementia patients for remembering their family members and friends. Here is our takeQuestionnaire page. This page is used by the patient to answer questions. In this image we use a placeholder but in practice would be a picture of a person.

Administrator
A user can begin using our system by making a Admin account from the login page. The admin would typically be a caretake, doctor or even a responsible adult. The admin can create accounts for family members and friends or if they already have an account, they can simply invite them. A family member or friend will be able to then create custom questions for the patient. Our app will collect all the questions created by the family and friends to create a questionnaire for the patient. The patient can then fill out the questionnaire as many times as they want and all records will be stored and given to the admin.
These features allow a family member or friend to create, delete and edit their own questions. Upon selecting the trashcan icon a confirmation screen will appear to confirm their deletion.
An Admin has many features, including editing and deleting everyone's questions, creating their own questions, reviewing the results of every questionnaire, an analytics page of questionnaire results, inviting additional admins, inviting family members and friends and setting reminders.

Accuracy of Computer Simulation of Posture Prediction in JACK compared to Xsens Motion Capture
Maria Arenas1, Xiaoxu Ji1
Biomedical Engineering1, Gannon University, Erie, PA
Abstract According to the U.S Bureau of Labor Statistics, there were 247,620 musculoskeletal injuries accounted for in the workplace in 2020 [1]. This makes it an important point of study because these injuries not only endanger employees, but they also impede job completion and reduce productivity in the workplace. Our study could help in the understanding of the differences that occurred difference between predicted DHM postures in dynamic simulation and actual human movement by analyzing what differs between each software, why these differences occur, and which should be the correct posture to prevent musculoskeletal injuries.
Methods
Results
In order to perform this study, the subjects were asked to perform the following tasks: Task 1: Participants needed to push a 40kg load forward with a distance of 20cm on the table. The height of table was 75cm. The distance between the starting position (Figure 3) and end position (Figure 4) were marked by tapes without medial-lateral offset. Also, two feet stood in parallel on the fixed positions. The distance between two fixed positions on the floor was 45cm as the average shoulder’s width. The horizontal distance from the standing position to the initial pushing position was 50cm in the anterior/posterior direction. Moreover, two spots were marked on the top corners of the box for hands grabbing. All those constraints could ensure no bias in experimental design. Task 2: Participants needed to pull this 40kg load back from the end position to the original spot. All constraints were also applied in Task 2. Each participant was required to push and pull the load as one cycle and repeated 5 times.

Aim: The goal of this research is to compare the accuracy of full-body dynamic simulation using TSB in JACK Siemens PLM program to real-time HM captured by the Xsens MVN motion tracking device. In this study we will focus on the analysis of a full-body dynamic simulation during the performance of pushing and pulling task. The phenomenon that this study is trying to analyze is the reasons of why predicted simulated movements can differ so much from the real human movement when the same task is being performed in both. Figure 2. Xsens MVN system [3]
Conclusion
Future Work
We successfully evaluated the accuracy of full-body dynamic simulation with the use of TSB within JACK Siemens PLM software compared to Real HM recorded by the Xsens MVN motion tracking system for pushing and pulling tasks. We analyzed and found out how postures can have an effect on spinal forces when performing different tasks, in this case pushing and pulling. The correlation that was obtained between a subject’s gender, body height and body weight to the different joint angles in dynamic movement and the effect of compressive and shear forces acting on the spine was another important point of focus. As well as, we were able to support and contrast the results that we obtained with ones that have been published by other authors. This comparison was done in order to analyze how close our results were and what differences were present in each of the researches that we compared to. Our study could potentially help obtain a robust ergonomic analysis when trying to study a full-body dynamic simulation by proving the accuracy of the methods and analyses done.
The hope for the future with this study is that by analyzing the deviations and differences that occur, one day the long-term goal of eliminating the need to record human movement and still being able to predict the desired and accurate postures will be achieved. As well as performing this analysis under different types of tasks and movements in order to see what types of different conclusions are reached. By doing this we can analyze if the same types of connections that were found in this experiment, apply for other kinds of activities that both females and males performed.

By using this approach, we were able to analyze the compressive back forces and the shear force present on the spinal segment of L4 and L5. For the push task, we found out that females curved their trunks while doing this task, while male tend to bend causing the trunk to flex and bringing the hip into flexion as well. We also found that when there was an increase of the subject’s height, they started to extend their trunks as they are completing the task. As well as, an important difference found between the between Real_HM and Predicted_HM was in the Sh_Abd/Ad, where in the predicted the shoulder performed an adduction motion while in reality the shoulder performed abduction. For the pull task, females curve their hip and flex their trunk at the same time, but male subjects do not perform this. This can be correlated to the fact that males rely more on their upper body strength than females do. Another relationship found in females was as the height of the subject increased, the angle of flexion for their trunk increased as well. But in the other hand, in the Predicted_HM the body height as the height of the subject increased, the angle for the flexion of the trunk actually decreased. With the analysis that we have done we can state that the flexion of both the trunk and the hip will affect the spinal forces on a subject, since they all increase and have a positive correlation within each other.

Title: Air and Water Pollutants: A Quest for Human Health in Erie, Pennsylvania Abstract: Various research has found the adverse side effects of pollutants to the health of people in industrialize and minority communities. With the help of GIS, we map the locations of industries within Erie County and analyze the spatial distribution of pollutants these industries reported to TRI (Toxic Release Inventory). The research also examines the spatial distribution of the pollutants related illnesses (hearth diseases, cancer and COPD) in Erie County. Along with these data, we also map density of trees in City of Erie and analyze if air pollution related diseases are lower to areas with high number of trees. Our research provides insight to the people of Erie on how to address this issue. Presenter(s): Madyson Bubb, Matthew Schlessman Sponsoring Department: Criminal Justice Project Mentor: Chris Magno

Alcohol, Drugs and Domestic Violence in Erie, Pennsylvania
Professor: Chris Magno
Jayme Kostial Kostial003@gannon.edu
Magno001@gannon.edu
ABSTRACT: This research examines the current nature, trends and factors affecting the local domestic violence in the city of Erie. Specifically, the research spatially analyzes the relationship between alcohol and drugs related offenses to domestic violence. Using graphs, maps and figures, the research illustrates the historical and spatial trends of Erie’s experience of domestic violence. This research reveals that the most common types of domestic violence are violations of PFA (Protection from Abuse Act), domestic disturbances, sex offense, sexual rape by force, assault, and sexual assault to rape. Cases of domestic violence also increased during the pandemic year of 2020.
Analysis : As you can see within the discolor-
ation, there are a lot of domestic violence cases in the Northern part of Erie Pa. You can see the hot spots for Domestic Violence as well.
Millions of Americans become crime victims every year. NIJ’s research has supported efforts to guarantee the rights of victims in various ways. “Victimization may happen to an individual, family, group, or community; and a crime itself may be to a person or property. The impact of crime on an individual victim, their loved ones, and their community depends on a variety of factors, but often crime victimization has a significant emotional, psychological, physical, financial and social consequences”. Most of domestic violence offenses occur when the predator is under the influence of drugs or alcohol.
CONCLUSION/RECOMMENDATIONS:
Analysis: It is interesting to see that the Drug misconducts are located directly in the middle of Erie County, which is very close to Gannon University. I think that allows us to focus more on who is involved and where to place the appropriate facilities to decrease the amount of drug use in our location. As well as drug overdoses.
In conclusion, there is a very big concern for the amount of Domestic Violence cases around Gannon University and other local Universities in Erie Pa such as Penn State Behrend, Edinboro and Mercyhurst University. I would expect, regardless of the location, that my presentation today has broadened your knowledge of domestic abuse. Whether it is focusing on more drug And alcohol facilities to help these addictions or it allows us to unite as a community and formulate more places for people to get help such as domestic violence shelters for victims and their children. We are capable of making these changes and minimizing the assaults for future men and women of our community. Analysis: To give a basic overview I have also laid out the domestic violence cases by street. Comparing all four maps you can focus on exact locations and look around to see the locations of drugs, alcohol and domestic violence cases individually.
BIBLIOGRAPHY: http://nij.oip.gov/topics/victims-of-crime
Analysis: Alcohol abuse is definitely the most scattered, but you can narrow down the hot spots which once again sit in the center of Erie which is right around Gannon students which is frightening.

An mRNA Cancer Vaccine Design Against a FAM46C Frameshift Mutation as Therapy for Hematopoietic Cancers Abstract
Leukemia is a cancer of the blood, manifesting in hematopoietic progenitors. Myeloid leukemia originates from somatic mutations found in common myeloid progenitor (CMP) cells. Similarly, lymphoid leukemia derives from cancer-causing mutations in common lymphoid progenitors (CLPs). Although the overall 5-year survival rates of all leukemia is ~65% and thus generally favorable, the overall mortality rate by leukemia in Americans has not changed much since 1975. Treatments vary on the specific type of leukemia, ranging from radiotherapy, chemotherapy and/or bone-marrow transplantations. We computationally identified a frameshift allele of human FAM46C that generated a novel antigen not found anywhere else in the human condition. This foreign epitope is thus an excellent candidate for a synthetic mRNA vaccine design. Our vaccine design would thus train the cytotoxic T lymphocyte (CTL) response against such a neoantigen, which comprise a major anti-tumor component in host immune systems.

The Cancer Genome Atlas was used to determine which gene had the most influence on rate of hematopoietic cancers due to a frame shift mutation. Once FAM46C was determined to be the gene with the highest rate of cancer associated with its frameshift mutation a software , Ensembl Archive, was used to find where this gene was located in the human genome. Then, using the NCBI Consensus Coding Sequence tool, the onco-antigen was determined for this mutation. The onco-antigen needed to be tested against the rest of the human genome to confirm that the sequence was not found elsewhere, this was completed using BLASTP software. Using this onco-antigen sequence, the final vaccine sequence was found using the Backtranseq software which turned the amino acid onco-antigen sequence in to a corresponding RNA vaccine sequence. Finally, the RNA vaccine sequence will receive additional components and be packaged for entrance
The FAM46C gene is found on the first chromosome in the human genome on the positive sense strand. The mutation resulting in a frameshift is an insertion single nucleotide polymorphism. The frameshift caused a missense mutation in the reading frame causing the cancer. The initial onco-antigen was found by comparing the wildtype polypeptide sequence to the mutated sequence. The difference of the amino acids between the two provided the onco-antigen. Once the initial onco-antigen sequence was found it needed to be checked against the human genome to the vaccine sequence could be formulated. BLASTP software was used to complete this and no similarities to the human genome were found. The onco-antigen was then changed from an amino acid sequence into a RNA strain, this strain is our cancer vaccine. In order to make this vaccine usable, different components needed to be added in order for the sequence to make it to the nucleus of the cell. Added to the sequence included a start and stop codon, a poly-A tail, as well as a Kozak sequence. The signal sequence was left off in order to target T-cell activation. Finally, the whole sequence with its added components will be packaged in a lipid nanoparticle in order to enter the body and be endocytosed by human cells.
Introduction Across the world Leukemia is one of the most common forms of cancer (Figure 1). It is also one of the most common forms of young adult and childhood cancer (Figure 2). This cancer attacks the blood cell forming hematopoietic centers within the bone marrow of long bones and lymphatic system (MayoClinic). In normal bone marrow tissue, the cells within will grow and divide at a rate set by the DNA, but with leukemia, the cells divide rapidly and cause overcrowding. The FAM46C gene was chosen due to the high level of mutation associated with cancer. Of the 260 cases analyzed in this study over 15% were caused by a frameshift mutation of the FAM46C gene, well ahead of the next closest gene (Figure 3).

An mRNA Vaccine Design Against a Frameshift Allele of the Human APC Gene as Therapy for Colon Cancers Deven Abbott , Matt Gacura , Gary Vanderlaan Abbott019@gannon.edu
Abstract
Introduction
Colorectal cancers manifest as uncontrollable cell divisions within cells of the colon or rectum. Often such cancers exhibit polyps which are abnormal growths, and removing such polyps are important in preventing further development of colorectal cancer. Five-year mean survival rates after diagnosis are ~64.7%. For metastasizing colorectal cancers however, the 5-year survival rate is only 14.7%. Although the last 40 years of treatment innovations have effectively cut in half mean mortality rates, new treatments are always needed. The most commonly mutated gene in all colorectal cancers is the tumor suppressor APC, which encodes a gene product involved in cell adhesion. We computationally identified a frameshift allele in the human APC gene that yields a neoantigen that is unique to the human condition. We then designed a suitable mRNA vaccine leveraging this foreign neoantigen for use in colorectal cancers exhibiting this precise APC
A cell might initially acquire loss-of-function (LOF) mutations in p53. This permits the cell to more frequently accumulate additional mutations at several loci, including within proto-oncogenes and other tumor-suppressor genes. Further mutations arise disrupting cell-cycle regulation, which grants elevated cell division rates. NK cells & CTLs begin to respond, but many cancer cells can promote activation of regulatory T (TREG) cells. If a TCR exists on a T lymphocyte such that it has affinity for such an onco-antigen, this can result in CD8-expressing CTLs to respond by sending pro-apoptotic signals to the cancerous cell displaying such onco-antigens via its MHC-I systems. The trick is to train the CTLs to look for such oncoantigens. The most commonly mutated gene in all colorectal cancers is the tumor suppressor APC. We use LNPs (Lipid Nanoparticles) to distribute the nanoparticles of the novel onco-antigen that we found in this study.
Method Step 1-: Locate a specific cancer mutation using NCI’s The Cancer Genome Atlas Step 2-Map the specific nucleotide lesion onto the human genome using Ensembl and CCDS Step 3-Check if onco-antigens share homology to existing human polypeptides using

LNPs are used to administer vaccines because once they are injected into the body cells will naturally endocytose them. Once they are in the cell, the lipid will be broken down and whatever was inside will be released into the cytosol. In this case mRNA strands will be released to be translated giving the individual artificially acquired immunity. The overall idea is to either prophylactically vaccinate persons at risk for specific alleles of certain cancers, or to boost CTL responses in persons already afflicted. Such vaccines are thus heavilypersonalized.

An mRNA Vaccine Design Against a Frameshift Allele of the Human GOLGA4 Gene as Therapy for Thyroid Cancers
Zechariah Gilbert, Matt Gacura and Gary Vanderlaan gilbert012@gannon.edu
Abstract:
Risk Factors of Thyroid Cancer:
Figure 1 (MHC and Onco-antigen): This figure is displaying a healthy cell. As you can see all peptide fragments are made by the proteasome and put onto the MHC-I to be displayed on the surface of nucleated cells. Degraded cytosolic proteins are normal in this figure and the MHC-I are displaying self-antigens. The T-cells don’t respond to these selfantigens. To the right is a cancerous cell, the frameshift mutation may generate Onco-antigens, which are novel polypeptide fragments. It is displayed through the MHC-1 and can activate Cytotoxic t leukocytes that will see them as nonself.
Treatment Options for Thyroid Cancer:
Patients with a history of radiation therapy administered in infancy or childhood for benign conditions of the head and neck (such as enlarged thymus, tonsils, or adenoids; or acne) have an increased risk of cancer and other abnormalities of the thyroid gland. In this group of patients, malignancies of the thyroid gland appear as early as 5 years after radiation therapy and may appear 20 or more years later.
Thyroid cancer manifests as four overall types: anaplastic, medullary, follicular and papillary. Papillary is the most common type of thyroid cancer, and each of the four differ in their aggressiveness. If caught early, the 5-year survivorship is over 98%. However, patients in which thyroid cancers have metastasized exhibit a 53.3% survival rate after five years of diagnosis. The mortality rate due to thyroid cancer has not dramatically changed in the last 40 years, hovering at an approximate 0.5 deaths per 100,000 Americans each year. We identified a frameshift allele in the human GOLGA4 gene that yields a neoantigen not found anywhere in the human proteome. Such a neoantigen is produced by only cancer cells harboring such a GOLGA4 mutation and is potentially an excellent target for vaccination. We then designed an mRNA vaccine to be used in thyroid cancer patients harboring such a GOLGA4 frameshift allele.
Current treatment options for thyroid cancer includes the following Surgery, Total thyroidectomy, Lobectomy, RAI therapy, Thyroid-suppression therapy, EBRT, Targeted therapy, Chemotherapy, and Systemic therapy Figure 1.
Figure 2.
Figure 4 (GOLGA4)
Figure 2 (Frameshift Mutation): A frameshift mutation is a mutation involving the insertion or deletion of a nucleotide. Frameshift mutations can cause the formation of these novel polypeptide sequences. Downstream of the lesion, a frameshift can occur due to the insertion or deletion mutations occurring in non-multiples of three nucleotides. The BLACK in this figure are areas that can yield novel nucleotides. Multiples of three nucleotides will not shift the reading frame but will allow for addition or subtraction of amino acids in the polypeptide sequence.
The vaccine developed indicated that the neoantigen is not found in any other human protein, this indicates that this vaccine is a good candidate for thyroid cancer associated with the GOLGA4 allele. A 5’-UTR is added for ribosomal invitation and an AUG was added to grant an ORF start. A signal sequence was not added to drive MHC-1 display favoring T-cell responses.
Figure 3.
Figure 3 (Metastatic Cascade): This figure is showing a multi-step process called metastasis. To the left is a primary tumor site where mutations have arose that causes the healthy cell to become a cancerous cell. The tumor cell obtains mutations that allow for its survival by evading host cytotoxic T lymphocytes and natural killer cells. Cancerous cells can enter the bloodstream when the tumor grows enough. This will cause more tumor colonies in other areas of the body.

Gastric cancer, the fifteenth most common form of cancer, occurs when cancer cells form along the lining of the stomach. Patients affected by this cancer are observed to have a five-year survival rate of just 32.4%, and in 2021 there were just over 26,500 patients affected with 11,100 patients dying from gastric cancer. Treatment efforts for this diagnosis include chemotherapy without radiation around the time of surgery, or monoclonal antibodies to aid in survival of the patient. Data obtained from the National Cancer Institute show a wide variety of genes that cause gastric cancer, of particular interest is ARID1A, which is seen is approximately 25% of all cases. Here we’ve designed an mRNA vaccine that works against a specific frameshift allele in ARID1A so that anyone affected by this specific somatic mutation can develop a cell-mediated cytotoxic T lymphocyte response against the cancerous tissue.

Displayed first on the OncoGrid (highlighted), ARID1A is at the top of genes mutated with a loss of CNV (copy number variations), displayed with the blue boxes. In addition, this OncoGrid shows the top frameshifted mutated genes, illustrating the frequency of the mutated ARID1A.

Stomach cancer can be promoted by factors such as diet containing highly processed foods, meals with high sodium content, and smoking. Recent morbidity trends illustrate a decline in cases, and the same can be seen for mortality rates. There is still a 5-year survival rate of only 32.4% in stomach cancer patients, making this likely that patients will not survive past 5-years after treatment.

Future Directions This mRNA vaccine is personalized to the patient that is suffering from the specific frameshift occurring in the first chromosome. Such that a patient should need this vaccine, it would first have to go into a pre-clinical stage to ensure provocation of an immune response and acceptance from the Center for Disease Control and Prevention. Approval will be needed to move into vaccination trials. Once accomplished, production of the liquid nanoparticle can be completed, and manufactured for injection into the patient.

Title: An mRNA Vaccine Design to Neutralize African Swine Fever Virus Infections in Pig Populations Abstract: African Swine Fever Virus (ASFV) causes African Swine Fever (ASF). ASFV is non-infectious in humans but lethal in pigs. Despite understanding the virology, there is no treatment/vaccine. The procedure for ASF outbreaks is quarantining and culling infected pigs. Food insecurity can result due to the loss of a vital pork protein source. China was greatly impacted by an ASF outbreak having catastrophic effects on pork availability making alternative proteins sources more popular, including wet markets associated with zoonotic diseases. An example of this is the COVID-19 pandemic which resulted from the wet market consumption of bats harboring SARS-CoV-2 virions. We have designed a tetravalent RNA vaccine targeting proteins for viral entry into porcine cells checked for potential anaphylaxis interactions. It can be tested to elicit a porcine immune response to generate neutralizing pig immunoglobulins. This results in stabilized food security, relieving the reliance on wild-life protein sources replete with zoonotic potential.

Astrocytes and Anxiety Disorders Natalie A. Carris, James J. Colvin, Jack S. Kloecker, Eileen K. Philips, and Prasad S. Dalvi Department of Biology Gannon University, Erie, PA, USA
Anxiety
Abstract Astrocytes are a sub-type of glial cells that interconnect and interact with adjacent cells and neurons in the Central Nervous System(CNS) to regulate their functions. Recent research has found that glia cells with abnormalities give rise to negative emotions such as anxiety, or a feeling of fear, dread, or persistent worry about everyday situations developed by the autonomic nervous system. Exposure to stress on a long-term basis can alter normal brain function, causing one to develop anxiety-like behaviors along with changes in the astrocytes. The exact mechanism by which these astrocytes affect our mood and behavior warrants further investigation. This review primarily focuses on the role of astrocytes in the regulation of anxiety behaviors through their interaction with neurons in the CNS and discusses whether the controlled activity of astrocytes can be used as a possible intervention to fully prevent or treat mental disorders.
Astrocytes
Figure 2. Emotional Centers, namely the Amygdala, in connection to the higher cognitive centers(top). The basic definition of anxiety is a feeling of fear, dread, or persistent worry about everyday situations. Symptoms of anxiety disorders are thought to be a result of the disruption in the balance of activity in the emotional centers of the brain rather than the higher cognitive centers. The amygdala, apart of the emotional centers, is known for processing emotionally important external stimuli and initiates the appropriate response such as fear and anger expression, defensive behavior, and formation and retrieval of emotional and fear-related memories (Figure 2). Astrocyte activity was found to selectively regulate specific synapses, both decreasing excitatory synapses and enhancing inhibitory synapses, reducing fear/anxiety expression in the amygdala.
Astrocytes and Anxiety Figure 1. Protoplasmic astrocyte (left) and Fibrous astrocyte (right). Glial cells, being the most abundant type of cell in the human brain, have an immense impact on the basic body functions. Astroglia cells, also known as astrocytes, are categorized as a subtype of glial cell that can be found in the CNS. Studies have found that there are two main types of astrocytes: protoplasmic and fibrous (Figure 1). Protoplasmic astrocytes can be found in the gray matter.
Patients who suffer with ongoing anxiety may be diagnosed with a form known as unpredictable chronic mild stress (UCMS). Exposure to stress on a long-term basis can alter normal brain function, causing one to develop anxiety-like behaviors along with changes in the basolateral amygdala (BLA), specifically reactive astrocytes. BLA are nuclei of the amygdala responsible for storing important information regarding fear responses. After 21 days of chronic light stimulation (Figure 3), BLA astrocytes showed to fully alleviate anxiety-like behaviors and UCMS-induced action. On a molecular level, more copies of S100, a calcium-binding protein that plays a role in regulating anxiety, were produced in the BLA, as well as increases in serum corticosterone concentration, a hormone known to aid in the control of stress responses.
Figure 3. Basolateral amygdala (BLA) astrocytes fully alleviate anxiety-like behaviors and unpredictable chronic mild stress (UCMS)-induced action under chronic light stimulation in mice.
Discussion Mood disorders, such as depression and anxiety, exist due to complex biological mechanisms and is incredibly difficult to treat due to futile neuron targeting. Astrocytes have been discovered to change the development of neurons and synapse connections. If astrocytes can be stimulated, they can release transmitters such as glutamate and lactate, essentially manipulating the formations of these neural connections. If it can be perfected, we can change how neurons and synapses are developed and help alleviate patients with mood disorders.

Title: Astrocytes and Anxiety Disorders Abstract: Astrocytes are a sub-type of glial cells that interconnect and interact with adjacent glial cells and neurons in the Central Nervous System (CNS) to regulate brain function. Recent research has found that glia cells with abnormalities give rise to negative emotions such as anxiety, or a feeling of fear, dread, or persistent worry about everyday situations developed by the autonomic nervous system. Exposure to stress on a long-term basis can alter normal brain function, causing one to develop anxiety-like behaviors along with changes in the astrocytes. The exact mechanism by which these astrocytes affect our mood and behavior warrants further investigation. This review primarily focuses on the role of astrocytes in the regulation of anxiety behaviors through their interaction with neurons in the CNS and discusses whether the controlled activity of astrocytes can be used as a possible intervention to fully prevent or treat mental disorders.

Compression Test of Bone Scaffolds with Triangular Pores at Different Porosities Ethan Swierski1, Quentin Justice1 2, Joshua Weiss1, Saeed Tiari1 Biomedical Engineering Program1, Mechanical Engineering Department2, Gannon University, Erie, PA
Background Bone scaffolds are used in cases where a serious break, removal of bone, or bone degeneration has occurred. They are used as a way to promote bone growth while providing support. Scaffolds need to be porous enough to promote bone growth, but at the same time, need to be strong enough to support the weight and other forces being exerted on it. If it is too porous, then the scaffold will break since it isn’t structurally strong enough. If it isn’t porous enough, then bone growth will not occur.
Future Work
Methods and Materials Each of the scaffolds was designed in Creo Parametric with triangular pores at 60%, 70%, and 80% porosity.
(a)
(b)
In the future, this same experiment can be done using various materials, different pore shapes, or even with various types of printers. Inorganic scaffolds could be made of various materials like titanium, hydroxyapatite, and PLA [4]. Metals and plastics can be 3D printed, so the same method can be done with them as well. Pore shapes can influence the compressive strength, so various pore shapes could be used at the same porosities and give different yield strengths. Finally, different printers have different resolutions and quality of printing, so that may also have an influence of the compressive strength for each of the porosities.

After the cubes were 3D printed using resin, their porosity was tested via water displacement. A solid cube would displace the water 16.39ml, so based on that, the actual porosity of each can be determined. There could possibly be Figure 1: An example of when and how bone scaffolds would be used

variation in porosity because the 3D printer’s tolerance may not be as fine as needed. After the porosity is determined, then compression tests with the MTI 2K will be done. Depending on where the scaffold would be used, the desired compressive strength would be from 14.5 ksi to 33.4 ksi [2].

Aim To determine the optimum porosity for a 3D printed bone scaffold. This will be done by compression testing three different 1in-by1in-by-1in cubes at 60%, 70%, and 80% porosity. The compression test will provide information on the mechanical strength of each porosity, which will then be compared to each other to see what the most porous and strongest scaffold is. That optimization of porosity and strength will provide the best porosity to use as a bone scaffold

Covid-19 Death Rates Per Pennsylvania County Focusing on Race and Poverty Levels By Maria Ondrejko, Rachel Tufts, and Sydney Johnston
Abstract: Using GIS, the goal of the research is to find any correlation between Covid-19 death rates versus poverty levels and race. These maps should highlight hotspots of Covid-19 deaths, along with other correlating factors. One goal of this research is to determine if Covid -19 affected specific racial populations due to geographical location or other specific biological factors could have played more of a role. A second goal of this research is to identify impoverished areas of Pennsylvania and compare Covid-19 infection rates to death rates. From this research, we hope to identify correlations between Covid-19 mortality rates and its effects on society as a whole in Pennsylvania.
Map 2 demonstrates the total deaths due to Covid-19 compared to race and population within each county of Pennsylvania. It is interesting to see that Philadelphia and Alleghany county has the highest concentration of deaths within all races. This is concluded as they also have the highest population by county as well within Pennsylvania. Elk and forest have the lowest concentration of deaths of Covid-19 within each race.
Map 3 and 4 demonstrates the poverty levels within each county of Pennsylvania. When analyzing this data, the PA Covid-19 Death hot spots are comparable to PA Poverty hot spots. The correlation between the two is interesting, as the highest poverty levels are also the highest death levels by County. These hot spots include York, Lancaster, and the surrounding counties. It is also interesting to note the cold spots are within the larger counties on the west side of the state like Allegheny and Westmoreland.
Map 1 demonstrates the total deaths due to Covid-19 within each county of Pennsylvania. It is interesting to note that the counties with the highest death totals are Allegheny and Philadelphia counties. The surrounding areas also held some of the highest death totals, and the counties in the middle of the state with the lower populations hold the lowest number of death totals. It is interesting to see that the counties with the two main cities in Pennsylvania both hold the highest death totals from Covid-19.
Conclusion: It is interesting to see that the highest populated areas also have the highest concentration of deaths and poverty levels. One suggestion could be increasing PPE distribution within the high poverty, high death rate areas as well as increasing Covid-19 testing. It would be interesting to look into if the poverty and race correlate within those areas. References: Cases and data. Erie County, PA. (2022, February 23).

What are white-rot fungi?
Growing white-rot fungi
This project primarily utilizes the oyster mushroom (Pleurotus ostreatus) as the basis for growth of fungal blocks. P. ostreatus belongs to the group white-rot fungi. They are capable of decaying wood and other materials with high cellulose content. Therefore, these mushrooms will be fast colonizers of substrates such as wastepaper and spent barley grain. Possible sources of white-rot fungi for fungal bricks are described below.
Spawn bags were filled with various cellulose rich substrates, including spent barley, shredded paper, and non-spent barley
P. ostreatus was inoculated in potato dextrose agar and cultured on potato dextrose agar plates.
A culture of P. ostreatus was acquired from Fungi Perfecti
Figure 13. MTI-10k
Once growth occurred in the plates and broth, the spawn bags were inoculated with P. ostreatus
The spawn bags were allowed to grow in room temperature

A pure culture of P. ostreatus [Figure 4] was used to cultivate growth on potato dextrose agar by taking plugs of the culture and inoculating them to various plates [Figure 5] . The plates were allowed to grow at room temperature. [Figure 6] Spawn bags were utilized for growth to maintain a sterile environment for the fungi to grow. The spawn bags are insulated and have air filters to block airborne contaminants while providing even gas exchange. Additionally, the spawn bags are designed to optimize fungal size. They were filled with spent barley grain from Lavery’s local brewing, recycled paper, and non-spent barley. They were autoclaved for additional sterilization and inoculated with P. ostreatus , once grown [Figure 7] . They are then kept in a dry area at room temperature [Figure 8].

This project aims to repurpose waste from local businesses in the Erie community into growing substrates for edible fungi such as Pleurotus ostreatus (oyster mushroom), a fast colonizer of substrates enriched in cellulose. Fungal bricks will be created and tested during the Spring semester of 2022. The two substrates selected are recycled paper and spent barley grains, both will be sterilized and inoculated to determine which will be most suitable for growing a strong biomaterial. P. ostreatus will be grown on these substrates at room temperature for 1 week, to allow for the maximum amount of biomass to be produced. After the production of fungal bricks, they will then be deactivated and preserved. The mechanical properties of the fungal biomaterials will be tested at various temperature using an MTI-10k.

Design and Constr uction of a Buoy to Extend Period in Lake Erie Molly Burke1, Nikoly Dos Santos2&5, Sydney Hanratty4, Kaylee Hatfield3, Daniel Hughes3, Lydia Nemeth3, Jacob Rudy5, Morgan Schreck1 Biomedical Engineering1, Computer Science2, Electrical Engineering3, Environmental Engineering4, Software Engineering5
Introduction
Technology
Testing
In Lake Erie, there are growing levels of algae, which at high levels, can be disruptive to wildlife and harmful to humans who swim in the lake. The current buoys help track the algae's growth, but they are only in the water from May– October, there is a wide amount of missing data that could be used to stop the algae’s growth and protect the lake and bay area. The Scholars of Excellence in Engineering and Computer Sciences (SEECS), a multi-semester program at Gannon University, is helping the Regional Science Consortium to engineer a submerged device that extends collection timeline and stores water quality data of Lake Erie. With the data collected from the extended timeline, the conditions under which algae is produced should become clearer and a solution for this problem can be created to save the lake.
The measurement systems consist of an Arduino Pro Mini microcontroller and various circuit boards, shown in Figure 3. There is an SD card reader/writer, a resistive temperature measurement chip, a dissolved oxygen measurement chip, and a real time clock. The Arduino Pro Mini was physically altered to get immensely low power drain, it’s power LED was cut, making it significantly less power hungry. The goal of this design was to maintain an immensely low sleep drain. Approximately 6 mA of draw during the sleep cycle, which lasts for 15 minutes as specified by the stakeholders. The system has two 36 Amp Hour batteries, shown in Figure 4, meaning that at its average current drain, it will last for 7-8 months of continuous operation before requiring a recharge. This allows for the system to autonomously collect data, track time, and maintain storage while completely isolated from external manipulation for a lengthy duration, which accomplishes the desired goal of this design.
After drilling holes into it for all the probes, the buoy’s waterproofness and buoyancy needed to be tested. To perform these tests, the buoy was kept underwater while being weighed down with weights inside for around an hour. This test proved successful, as no water had managed to get into the bucket itself throughout the test. In addition, the buoy electronics' ability to handle cold temperatures needed to be tested. For this testing, the electronics were placed inside of a refrigerator over the course of a week while checking the internal components each day. In the end, this test proved successful as well, as the components functioned properly. There are also plans to test both qualities at once by placing the buoy inside of an ice bath sometime this semester.

Anchorage
Containment
The buoy must be fully submerged underwater to keep it safe from possible ice damage. To do this, the plan is to anchor the device down with a metal chain. The length of the chain will be short enough to keep the buoy a safe distance from the surface of the lake to avoid ice. The chain will be connected to the metal rod coming out of the bottom of the buoy, shown is Figure 5, and to concrete blocks in the sand at the bottom of Lake Erie. The Regional Science Consortium already has concrete blocks to anchor the summer buoys that are not used during the time the submerged device will be deployed. Since the Regional Science Consortium has concrete blocks, the plan is to use their blocks to attach the metal chain and device. This also narrows down the anchorage location for the buoy to a location of one of the Regional Science Consortiums summer buoys after it is taken out of the lake.
The buoy’s components are encased in a white bucket, shown in Figure 5. Previously, the components were to be encased within a 3D printed shell, but that idea was abandoned in favor of an existing water-tight material. This bucket has a screw-on lid and has been sealed with a combination of caulk and Flex Seal. The lid is watertight, but can be easily removed. This containment method was chosen as it fits all components easily and contains enough empty space to both float and resist damage due to pressure at its depth in Lake Erie. Likewise, the bucket is easily customizable and easy to drill through to fit each component. The dissolved oxygen probe and thermistor extend out of the bucket to be used for data collection while submerged.
As the project continues, we have several major steps planned. Before implementation, the DO probe and thermistor must be calibrated; current issues with the calibration process have caused the project to need repurchase probes as they have been damaged. The current battery casing is going to be remade. The current casing is made out of styrofoam and covered in duct tape; the new case is going to have a 3D printed shell that will be filled with expanding foam. The hope is that this new casing will have more structural stability. As additions are made to the bucket, primarily additions involving holes drilled into the bucket, waterproof testing must be reconducted to ensure any seals that have been made. A manual has been started and will contain information about how to use the buoy and why each component was chosen for the buoy. One of the final steps is choosing the anchorage for the buoy. The hope is to implement the buoy in the lake by next year’s winter season.

Introduction
Materials and Methods
Results
Machine learning is a novel, growing section of computer science that allows a device firmware to change itself or “learn” based on information fed into the device.
To determine the difference between various colors, an optical biosensor is used to determine the amount of red, green, and blue pigment in a sample. These levels of pigment are used to characterize a color’s identity. The optical biosensor was held in a 3D printed capsule and was implemented with an Arduino microcontroller in order to read the data and command the optical biosensor. Red, green, and blue light are flashed momentarily and simultaneously read by the optical biosensor in specified intervals. This allows the pigment concentration values to be detected.
This project yielded many important results. The algorithm was able to confidently and accurately identify certain colors such as blue and green. It also gave very strong levels of confidence for the predictions made even when incorrect. This suggests an incorrect model may be being used. Future work includes experimenting with new models and methods.
For example, CAPTCHA tests are used to verify the in person login for various websites (select the pictures with the cross walk, stop sign, etc.) are used to train self driving cars to recognize a speed limit sign from say, a pedestrian walking down the sidewalk.
This project was performed using a two stage machine learning process. The first stage used a classification neural network to detect the color of a sample. Following this, a linear regression model was used in order to determine what the concentration of said color is. The neural network is trained via a classifier MATLAB network. Meaning, the color is stated by the individual inputting the cuvette before the algorithm reads its pigment values. A hyperparameter must also be chosen for this technique. A hyperparameter will determine how closely the algorithm will fit its “prediction curve” to the read data. Lower values will result in underfitting while higher values results in overfitting. This suggests a “sweet spot” for the hyperparameter. The effects of underfitting or overfitting can be seen in the following figure.
In this project, we sought out to train an AI to identify the colors in various cuvette samples and the concentration of said color. While it is difficult to imagine why such a project would be useful, consider the application of this idea in the biomedical field, where instead of colors the viral load of a disease is detected instead. One can now hopefully see the power of such a project and how it may eventually contribute to the quick and efficient detection of disease.
Figure 2. Fitting Data using the Hyperparameter
Future Work To improve upon this project, we are considering implementing higher quality optical biosensors. Biosensors with the ability to read a wider range of pigments stand to better identify colors and thus improve results. We are also considering exploring with new hyperparameters. As it currently stands, 7 seems to be the best choice, however, there is some evidence that points to potential underfitting. Figure 3. The Training Samples
Figure 1. Example of ML: Google Quick Draw
For this project a hyperparameter of 7 was chosen. The second part of the model involved a linear regression model. Linear regression involves the process of fitting a linear equation to a set of data. This model was used to predict the concentration. By implementing this two part model of neural network and linear regression system, an optical biosensor can read and feed the color’s data into the algorithm and predict its color and concentration.
Title: Design of a Cost-Effective Optical Biosensor Powered by Artificial Intelligence and Machine Learning Abstract: Machine learning is a novel, growing section of computer science that allows a device firmware to change itself or “learn” based on information fed into the device. It is not uncommon for many well-versed technicians in machine learning to not understand how the device’s algorithm even functions due to its complexity and ever-changing nature. Regardless, this branch of science has numerous applications. In this project, an AI and machine learning algorithm were programmed and trained to identify colors in cuvette samples. A 3D printed capsule integrated with an Arduino microcontroller and optical biosensor was used to ascertain the red, green, and blue pigment in a sample. By training this algorithm with data from many different colors with many different concentrations, the AI could reliably detect the identity of a color placed into the apparatus. Future developments include the eventual extension into the biomedical engineering field. For example, the number of microbes in a blood sample could be detected, leading to a quick and efficient diagnosis of a potential disease.

The adrenal gland is critically important to one’s ability to maintain homeostasis as it regulates the release of hormones which dictate key life functions including blood pressure, metabolism, and stress response. The exact cause of adrenal glandular cancer is unknown, but it is more prevalent in families with a history of Carney Complex, Li-Fraumeni syndrome, or Neurofibromatosis type 1. These cancers are rare, but the 5-year survival rate is approximated at 38-46 percent with the most extreme stage having a 5-year survival rate of >20 percent. The best available treatment for those afflicted with stages 1-3 is surgery, and chemotherapy (mitotane) is used for patients in stage 4. We set out to design an mRNA vaccine that would expose cytotoxic T cells within the host to the neoantigen found on carcinogenic adrenal glands with the frameshifted PRKAR1A gene.

Designing Hydroponic Garden Systems for the Homes of L’Arche Erie Clara Almeter* , Olivia Graham*, Justice Jones**, Spencer Miller***, Andrew Mottola***, Ashlynn Uzl**** *Environmental Engineering, **Electrical Engineering, ***Biomedical Engineering, ****Mechanical Engineering Abstract
Nutrient Film Technique
The Gannon University Scholars of Excellence in Engineering and Computer Science (SEECS) Program has been tasked with developing and implementing an efficient hydroponics gardening system for the L’Arche Erie community. The SEECS class was divided into three groups, each assigned a different L’Arche home and each system has been designed according to the specific location.
● Nutrient rich water is pumped from a reservoir into a larger
tube/pipe ● The gentle slope of the pipes use gravity to allow a thin layer of water to continuously run across the plant’s bare roots ● The water returns to the reservoir to be cycled through the system again
Drip System
● Nutrient rich water is pumped from a reservoir and
distributed to the base of each plant through individual tubes
● The water drains through the plant roots, collecting in the
tray and uses gravity to drain into another tube to be individually distributed to the plants on the next tray
● The water returns to the reservoir to be cycled through the
system again
L’Arche Erie is a faith-based community that provides unity and growth to those with intellectual disabilities. L’Arche Erie owns various homes where their core members can live and are given the opportunity to personally and professionally develop.
Nutrient Film Designs
Requirements ● Easy to use and access for the core members of L’Arche
● Minimal maintenance ● Efficiency to maximize production rate ● Proper nutrition and lighting conditions
Rose Home • Adequate natural lighting • Growing only herbs
Drip System Design Oasis Home ● Not adequate lighting: requires built in lighting ● Larger design: requires larger pump size ● Growing lettuce and herbs
Constraints ● Size (dependent on home) ○ Cannot fit and maintain a large, complicated hydroponic system

L’Arche Erie is a faith-based community that provides unity and growth to those with intellectual disabilities. L’Arche Erie owns various homes where their core members can live and are given the opportunity to develop personally and professionally. SEECS students have done extensive research into the various types of hydroponic garden systems and produce types that will work best for each system. The SEECS class was divided into three groups, each assigned a different L’Arche home. Each system has been designed according to their specific home, ensuring cost and energy efficiency as well as minimal maintenance requirements, all while maintaining proper safety conditions. We look forward to continued communication with the L’Arche community to implement these systems within the homes in the near future.

Four serial dilutions of each of the four meat samples were made (including the cumulative dilution of 10-1, 10-2, 10-3, 10-4). The inoculation of the agar plates was done using the spread-plate method.
▪
The plates were incubated at 37°C for 48 hours. A "countable plate” was chosen from each treatment from the serial dilutions. A countable plate is determined by qualitatively observing which of the plates have bacterial colony counts between 30 to 300 colonies.
▪
The number of colony forming units (CFU) were then counted on all countable plates (as shown in table 1).
▪
The standard plate count (SPC) is then calculated by using:

This study in unique, as there is little to no literature on this subject specific for the Erie, PA region. Our study will help determine if higher quality meat and higher socioeconomic status play a role in the pathogenicity of ground meat.
▪
Additional observation such as store cleanliness and form of packaging could also play a role in how safe the meat is.

▪ The counts of bacteria found on EMB agar were an order of magnitude or less than what was seen on LB agar. This was expected, as LB agar is much more generalized media and should display a wider range of bacteria capable of growth. ▪ In contrast to what was seen in big box stores, smaller more localized markets did not appear to have as clear cut of pattern regarding meat quality and microbial load. ▪ Store 2 appeared to show the highest amount of microbial growth, with high grade surpassing low grade meat. ▪ Once again it was noticed that some stores did have higher loads of microbes ▪ There was no obvious effect of store location and microbial load detected. ▪ More stores will need to be tested before statistical analyses can be performed.

Breaking Down Big Box Stores
The USA has relatively low rates of infection due to the regulations enforced by the Food and Drug Administration (FDA), but it is impossible to provide 100% pathogen-free food products. These types of microorganisms will be more likely to occur in foods with poor sanitation and may arise lower quality food.

LB Agar is a nutrient rich medium used to culture bacteria of the Enterobacteriaceae. This agar allows fast growth and good yield of different types of bacteria.
If pathogens are present when meat is ground, more meat surface is exposed to harmful bacteria. Bacteria multiply fast in temperatures between 4.4-60°C. For this reason, its important to store ground beef at 4.4°C and use within 2 days, or freeze. To destroy bacteria, cooking ground beef thoroughly is important.

▪ Aerobic bacteria were an order of magnitude or higher than anaerobes ▪ A significant difference (p-value = 0.0003) was seen in the bacterial counts between meat types. With low quality meat being much higher than all other samples. This pattern was seen at sites and samples. ▪ While some stores did have higher loads of microbes, no significant effect of location in the city could be detected.
While other studies have focused on just determining the types and number of bacterial colonies present in different meat products, This study has focused on filling a gap in existing research by determining how the price/quality of ground beef effects the number of bacterial colonies present in meat. It also effects the consumer and their exposure to varying foodborne illnesses.

Introduction:
• Microplastics in Lake Erie can greatly affect aquatic life • Microplastics can originate from filters, fibers, or can be broken down from larger plastic products • Aquatic organisms ingest microplastics, affecting the food chain. • Humans eat contaminated fish. • To solve microplastics issue, it must be removed • Lake Erie has 380 tons of plastic • Its rough waters and ability to break down larger plastic makes it susceptible to create microplastics. • The surface water of Lake Erie contains about 43,157 plastic particles/km2. • Plastics can take hundreds to thousands of years to break down and decompose • Without remediation they could destroy the environment. Figure 1
Figure 3
The image at right shows microplastics density within the Great lakes watershed. As shown, microplastic pollution is especially prevalent in Lake Erie with a large concentration found on the eastern side of the lake. Our system will first be deployed in this area near Erie with hopeful expansion towards Buffalo and Cleveland. Allen 2020
The image above shows a fish with microplastics taken from its stomach contents. Plastic pollution in the world’s waterways contaminates fish after they ingest the plastics.

DAMPR’s main design objective is to remove microplastics from Lake Erie. The design utilizes inflow, outflow, and settling velocity. Water enters the top of the clarifier at a specific rate using a pump and forces water to overflow out of the top. Objects with specific densities could either settle or overflow with the water. This is due to the settling velocity of the objects. If the goal is to remove the objects the overflow rate needs to be greater than the settling velocity. Once the objects overflow they can be filtered out. The remaining objects with greater settling velocities would settle and create sludge at the bottom.

Issac 2021
Goal:
DAMPR is designed to achieve removal of plastics as small as 300 microns, which has not yet been created. The removal of such size is extremely significant as the use of plastic, as well as its disposal, continues to increase. Ultimately, this functioning microplastic filtration system will achieve optimum removal of plastics with minimal impact to the aquatic environment. The system is fairly inexpensive compared to competitors and due to its solar power system will be relatively self-sustaining. The main objectives were to determine the overflow rate needed for microplastic removal, design parameters and materials required, final construction and testing of a prototype.

Title: Device for Active Microplastic Removal (DAMPR) Abstract: Microplastics, which bioaccumulate through food chains and result in contaminated food supplies, have become a common pollutant in the Great Lakes. Of the Great Lakes, Lake Erie has the highest amount of microplastics and worst water quality. The existing plastic removal devices are not capable of removing microplastics without disrupting or damaging the environment. The new device, Device for Active MicroPlastic Removal (DAMPR), is able to remove plastics as small as 300 microns. Ultimately, this functioning microplastics filtration system will achieve optimum removal of plastics with minimal impact to the aquatic environment where it is deployed. The system is of a low-cost relative to competitors and should be relatively self-sustaining.

Findings & Results
Abstract
Birth control pills consist mainly of three weeks of active pills, which are those that contain the hormones, and one week of placebo pills, which are often called sugar pills and do not contain hormones. By adding pills into one’s life, periods become more manageable and predictable for women as they come once every month.
Oral contraceptive pills, also known as OCPs are one of the most easily and readily available prescriptions offered to a woman, sometimes starting at young ages. This literaturereview research focuses on both helpful and harmful effects a woman might experience when taking OCPs. It was found that most women are prescribed OCPs intended for helpful effects like clearing acne, lightening a woman's menstrual cycle, preventing unwanted pregnancy, and many others. With that, it was also found that these helpful measures tend to lead to harmful side effects, such as cardiovascular system problems, certain cancers, and mental health struggles. These effects were mainly found due to the prescription of synthetic hormones effecting the body's natural systems. Overall, this research looks at the effects of being prescribed OCPs and what it can do to the human body.
How long are they used?
A typical women’s menstrual cycle will continue for 40 years of their life, having a single period once a month. That is roughly 480 periods in a women’s lifetime. Between ages 45 to 55 is when women hit a cycle called perimenopause leading into menopause. Menopause is known as a pause in a women’s monthly cycle, where she does not receive a period every month and soon begin to stop (“Your Menstrual Cycle”, n.d). Most women will start use of oral contraceptives early on in their menstruating years and continue to use it until the age of natural fertility is lost, menopause.
Harmful Effects
With long continuous use of oral contraceptives comes affects to the body, as one should expect from providing their bodies with synthetic medications over a longevity. (Peck, 2021).
Conclusion
Helpful Effects
Heavy Menstruation: • Thin the lining of the uterus • Cause lighter periods • Less bleeding for a woman • Stopping period together (“Noncontraceptive benefits of birth control pills”. n.d). Endometriosis: • The lining of the uterus grows outside of the uterus causing many complications and very unmanageable and painful menstruation. • Progesterone within the combination pill can limit the growth • Eliminate the growth of the lining all together • Cause better menstruation as well as less pain (“Noncontraceptive benefits of birth control pills”. n.d).
Introduction
There are currently three types of oral contraceptives on the market to be prescribed. Those three are the combined estrogen-progesterone, progesterone only and the continuous or extended use pill. 25% of women within the US are prescribed and use oral contraceptives. The most common form that is chosen by most women is the combined pill of estrogen and progesterone (Cooper, 2021). Progesterone is a steroid hormone that prepares your uterus for the implantation of an embryo if fertilized. If fertilization does not occur, the progesterone levels within your body will drop realizing there is no embryo, and it will cause a woman to start menstruation (“Hormone”, 2021). Estrogen is one of two main sex hormones in a woman’s body, along with progesterone. Estrogen is what is required for a woman to have her physical features and reproduction abilities (“Hormone”, 2019). For the three forms of oral contraceptives, the progesterone works to prevent pregnancy and the estrogen controls the bleeding, they often just differ on the ways they are taken. While 25% of woman in the US are using the birth control pill as their main form of pregnancy prevention, the pill is also used for non-contraceptive reasons and other health conditions. 14% of woman who are using the pill are using for non-contraceptive reasons (Cooper, 2021).
Acne: • Reduce levels of male hormones, mainly androgens, in the female body (“Which Birth Control”, 2019). • The progesterone can reduce gland activity while estrogen can decrease the size of sebaceous glands as well as decrease sebum production leading to less acne production (Ghosh et al. 2014). Menstrual Pain: • Reduce the number of uterine contractions women undergo causing cramping. • Reduce the amount of prostaglandin produced preventing ovulation • Leads to less painful menstrual cramping (“Noncontraceptive benefits of birth control pills”. n.d).
Mental effects: • Most start using during their puberty ages, which is a crucial stage in brain development. • Women often turn to oral contraceptives to control unintended pregnancy and receive the anxiety and depression that may come with it. • The pill contains synthetic estrogen and progesterone which interact with mood related neurotransmitters in the brain causing different reactions to a woman’s mental health (Hall, 2015). • Tryptophan, an amino acid lessened by the pill is used in the creation of the neurotransmitters serotonin and melatonin. • Serotonin and melatonin are often related with depression and the lack thereof. • Depressive moods and association are often also related to the progesterone in the oral contraceptive and the levels an oral contraceptive may contain.
Cardiovascular System: • Synthetic progesterone and estrogen within the combination pill causes lipid profile changes leading to effects • Largest cardiovascular effect is Venous thromboembolism (VTE), also known as blood clots • Causes Deep Vein Thrombosis (DVT), blood clot forms deep in vein (“Deep Vein Thrombosis”, 2020). • Pill Increases bloods’ ability to clot by increase in plasma fibrinogen and coagulation factors • Causes Pulmonary embolisms (PE), known to be a blockage of the pulmonary arteries within the lungs from clots (“Pulmonary Embolism”, 2020). • Amount of estrogen within the pill as well as the type of synthetic progesterone, may affect developing blood clots within one’s body Cancer: • Oral contraceptives are associated with increased risk of breast cancer and cervical cancer. • They leave higher risk of being diagnosed with breast cancer over not using an oral contraceptive due to increase in hormones (Malone 1991). • Women using oral contraceptives for five years or more are more susceptible to having cervical cancer than those who don’t use oral contraceptives. • Birth control contains synthetic versions of the hormones progesterone and estrogen, thinking it is related to increasing cancer risks (“Oral contraceptives”, n.d).
Overall, oral contraceptives have been used as a preventative form for pregnancy as well as many other health reasons for a woman. As much as they can be helpful in controlling menstruation, they can also be detrimental to health with grueling side effects. These oral contraceptives are highly and easily recommended to almost every woman who is a healthy candidate for birth control. It’s important to ask how much these pills will affect one’s life and truly take in account the side effects they may bring. Patients do suffer from health-related risks while taking oral contraceptives and should truly question if living their lives out of a pack of colored pills is a path their willing to take.

Title: Effects of Oral Contraceptives on the Human Body Abstract: Oral contraceptives pills, also known as OCPs are one of the most easily and readily available prescriptions offered to a woman, sometimes starting at young ages. This literature-review research focuses on both helpful and harmful effects a woman might experience when taking OCPs. It was found that most women are prescribed OCPs intended for helpful effects like clearing acne, lightening a woman’s menstrual cycle, preventing unwanted pregnancy, and many others. With that, it was also found that these helpful measures tend to lead to harmful side effects, such as cardiovascular system problems, certain cancers, and mental health struggles. These effects were mainly found due to the prescription of synthetic hormones effecting the body’s natural systems. Overall, this research looks at the effects of being prescribed OCPs and what it can do to the human body. Presenter(s): Courtney Gluz Sponsoring Department: Biology Project Mentor: He Liu

Efficacy of Hexagonal Osteoconductive Scaffolds at Various Porosities for Bone Repair
Maria Arenas1, Molly Burke1, Jessica Bernat1&2,Saeed Tiari1
Biomedical Engineering1, Mechanical Engineering2 Gannon University, Erie PA
Introduction Osteoconductive scaffolds are an upcoming method that can replace the casting of bone fractures with an in vivo supportive structure that promotes bone regeneration [1]. Scaffold pore geometry and density influence the interaction of bone formation components at the repair site, for which this study seeks to determine the most ideal structure to maximize its effectiveness.
Design Concept
The models are scaffolds with hexagon-shaped pores with porosities of 75%, 80% and 85%.
Figure 3. CAD design for 75% porosity scaffold
Figure 1. In vivo scaffold embedded on the top of a bone [2]
Figure 4. CAD design for 80% porosity scaffold
Expected Results
The strength of the model is expected to weaken as the porosity of the design increases. In order to create less volume within the object, the thickness of the walls must decrease; therefore, the foundation of the model has less stabilization and becomes more prone to failure. Based on the three porosity chosen, it is believed that the 75% porosity will be the best option due to the supportive structure and the sufficient pore size to allow for tissue adherence and bone growth.
Figure 5. CAD design for 85% porosity scaffold
Next Steps
Procedure
The scaffolds were first designed using Creo 8.0.1.0 Parametric CAD software, then exported as an STL file and printed into a model with the Prusa 3D Printer shown in Figure 2. The material that will be used is Polylactic acid (PLA) since its relative inexpensive and efficient printing properties [3]. Four samples of each of the porosities designs will be printed in order to undergo the testing.
After the desired model passes the testing phase, the product would need to be submitted for FDA approval. The hope is this osteoconductive scaffold will bring beneficial qualities to the medical device market, including decreased recovery time, reduced threat of infection, and an improved bone quality repair when injury occurs.
Mechanical and Quality Testing Using the MTI 2k testing machine, the mechanical property of compression will be conducted on the models. This testing will predict how the scaffolds will preformed once inserted into the body. It is necessary to have the strength to withstand a large amount of force without failure, similar to how a bone can uphold the body’s mass. For quality testing, the porosity of the models will be reassured through a volume test. This procedure consists of calculating the volume change of the initial amount of water versus the remaining amount of water once the scaffold is placed into the cup.

Title: Efficacy of Hexagonal Osteoconductive Scaffolds at Various Porosities for Bone Repair Abstract: Bone fractures and deficiencies are challenging to repair, and patients are often hindered by extensive weight bearing restrictions or bone stabilizers. Osteoconductive scaffolds hold promise of speeding up recovery time, reducing infection, and improving the repaired bone quality. Scaffold pore geometry and density influence the interaction of bone formation components at the repair site. This study seeks to determine the ideal geometry and porosity of an osteoconductive scaffold to maximize its effectiveness. The 3D-printed models will have hexagonal pore geometry of 75%, 85%, or 95% porosity. Finally, mechanical testing will assess the scaffolds’ resistance to expected body forces.

Our data show that as UV exposure time increases, E.coli decreased in SURYA, with a greater effect in foil-lined SURYA designs. Our SURYA also exhibits a gradient effect across the position of the plates, with more germicidal effects in plates nearest the UV bulb. Our findings also illustrate that PRIMACE does not exhibit manufacturer claims of 99.99% germicidal strength unless used GDCM for 30 minutes. Our foil-lined SURYA designs achieved the same level of killing rate at just 5 minutes of UV irradiation as PRIMACE at 30 minutes. GDCM = Guandong Detection Center of Microbiology, China

UV sterilization is popular due to its ability to kill rapidly without the use of chemicals. Ultraviolet light is a useful sterilizing agent against electronics, water, and even air. One commercial product example is the PRIMACE chamber. We tested our Gannonengineered SURYA chamber against PRIMACE to compare the efficacy. All counts were performed using a Quebec colony counter.

The concept of ultraviolet (UV) irradiation as a disease control method is nearly a century old. As early as 1937, UV lamps were installed in a K-12 elementary school (Swarthmore Public Schools, PA) and the effect of UV irradiation on various childhood disease metrics including measles was tracked in a longitudinal study (6-year duration). This study revealed that UV irradiation reduced the weekly measles incidence in the students. Today, commercial UV-sterilization chambers are abundant. We examined the antibacterial efficacy of the commercially available PRIMACE against our own design, SURYA (Speedy Ultraviolet Radiation Yielding Antimicrobial effects). In our comparisons, we employed Escherichia coli on media containing ampicillin as our strain was ampicillin-resistant (at 100 ug / mL). In each sterilization chamber (PRIMACE vs. SURYA), we tested three different durations of UV-exposure: 5, 10 and 30 minutes. Each timepoint was then performed in triplicate to provide statistical robustness.

Enhanced Green Rooftop Design Emily Breniser, Peter Frisina, Shania Petrush, Alexa Rogers, Dr. Varun Kasaraneni Departments of Environmental and Mechanical Engineering, Gannon University, Erie, PA Abstract
Rooftop gardens, or green roofs, offer a wide array of benefits to urban centers where green space is limited, and impervious surfaces are plentiful. Urban areas face challenges such as flooding from stormwater runoff as well as air and water pollution. Green rooftops can help to mitigate these issues, but benefits are seen more significantly when they are implemented on a larger scale. The research conducted considers challenges associated with green roofs and climate change trends. The project aims to provide improved drainage capabilities which can handle the predicted increase in precipitation, while being able to retain the water long enough for treatment of acidity. An aesthetically-pleasing garden model will be designed, and a bench scale construction of the system will be used to test its ability to meet these goals.
Benefits • • • • •
Prevents flooding during peak precipitation by retaining water Restricts runoff from carrying pollutants into bodies of water Provides habitats for pollinators Reduces energy use for heating and cooling Allows the opportunity for water collection and treatment
Figure 3: Green rooftop used for agriculture designed by Brooklyn Grange Farms
Project Goals 1) Optimize drainage in the substrate Permeability of soil mixtures were investigated. Media contained varying amounts of light expanded clay aggregate, perlite, mushroom compost, and biochar. Porous, absorbent, and lightweight materials were prioritized while considering weight restrictions.
2) Build model with bestdraining substrate and custom drainage layer
Figure 5: Hydraulic conductivity testing apparatus
Introduction
Stormwater management is becoming increasingly important as climate change progresses. In urban settings, the sewage systems can be overwhelmed during storm events. • Average annual rainfall has increased worldwide over the past century¹ • The capacity of air to hold water increases by about 7% per 1°C warming² A green rooftop is a way to retain rainwater that can also serve as a source of beauty and space for relaxation.
Figure 1: Flourishing Cantor Rooftop bar in NYC.
Challenges In order to effectively manage stormwater, green roofs must maximize water retention while managing other factors such as: • Selection of media for each functional layer • Leakage; prevention, detection, and repair • Maintaining or improving building aesthetics • Added weight to be distributed on rooftop; safety concerns • Species selection and establishment
Figure 4: Retrofitting some type of rooftop garden to an existing building is almost always possible, but may not be costeffective. Installing a rooftop garden is cheaper for new structures, and allows for more creative freedom in designing.
Rainwater Quality • The pH level of rain in NYS is between 4.0 and 4.5 ³ • Most organisms prefer a near-neutral pH, and many sensitive populations die when pH is about 5 ⁴ • Acid rain can cause toxic metals to be leached from soil into larger bodies of water, which could potentially lead to illness in humans if ingested • Main cations and anions to be removed are phosphorous, nitrate, calcium and magnesium
Design Considerations
The nature of the drainage layer to maximize water retention and hold water against the filter fabric means that water must flow through the soil well enough to prevent root rot and support healthy plants. The goal of water retention is largely achieved in the drainage layer beneath.
Figure 6: Typical green roof design with added enhancements
3) Treat acidity by adding mussel shells • Mussel shells and other sources of lime were compared for their ability to raise the pH of synthetic acid rain passed through the system • Water collected at outlet was also measured for fertilizers to ensure no significant leaching
4) Apply design to existing buildings • Determine what areas of a roof can support what loads • Place overflow outlets accordingly

Abstract There are many implications of digital human model (DHM) technology into different applications, including aviation, automotive industry, military industry, energy industry, and industrial plants [1]. This evaluation is necessary as many workers, in both industry and healthcare, have been reported to have musculoskeletal injuries due to poor posture in everyday activities they perform on a daily basis. Through a study consisting of two real life human movements, moving a patient from a wheelchair to a bed, as well as helping a patient move from the wheelchair sitting position to a standing position, the forces on the body can be compared to standard, healthy, force values to determine the likelihood of injury. This technique can then therefore be used to help prevent these injuries in the future. Introduction In 2018, registered nurses and nursing assistants reported that over 23,000 days were missed from work, due to a musculoskeletal disorder caused by their chosen occupation. [2] Xsens Motion Capture System (Fig. 1) can beconnected to Jack Siemens PLM Software (Fig. 1), a DHM technology, to determine the likelihood of injury in healthcare workers.

Specifically, healthcare workers endure these injuries due to the repetitiveness of their tasks such as transferring patients from the bed to their chair, or the chair to the toilet. [3] Xsens Motion Capture System consists of many sensors that are placed on specific areas of the body Fig. 2 Manikin performing real-life movements in Xsens Motion Capture System (left) being constrained to the to record. manikin in the Jack Siemens PLM Software (right). Zohar Potash, Yaar Harari, and Raziel Riemer performed a study showing the effect of using real motion versus predicted motion as an input for digital human modeling, showing that it is much more accurate. [4] Some real-life human movements exceeded the “healthy” threshold, of 3400N, on the spine, however, the predicted motion never exceeds it., emphasizing that the predicted movements do not prove as accurate. [4] The objective of this study is to analyze the forces on the body during two specific movements. This technique can then therefore be used in the future in many applications such as helping prevent future work-related injuries, helping to design future assist machines in the workplace, or with any analysis regarding the forces and angles applied on the human body during movements.

Abstract What counts as toxic to a particular biological species may be entirely non-toxic to another. Acrylic bonding agents (ABs) are commonly used in numerous industrial applications. In liquid form, ABs have been shown to be exceptionally harmful in many different animal studies, including humans. ABs have not been fully investigated in plants. A contrasting example is silicone, used in clinical settings as bonding agents. Silicone exhibits no toxicity profile in humans, and like ABs, silicone toxicity in plants is also not fully investigated. All plants execute a lifecycle of alternating generations. However, ferns are unique because they possess free-living gametophyte and sporophyte stages. Ferns allow us to not only test whether certain chemicals are phytotoxic, but also if these chemicals are specifically toxic against gametophytes and/or sporophytes. Here we show data that evaluate the plant toxicity of ABs and silicone on developing gametophytes in the model fern organism, /Ceratopteris richardii/.

Macroscopic view of Ceratopteris richardii gametophytes (24 dps) exposed to differing bonding agents. Note the complete absence of green plant development in the silicone-exposed treatment group.
The life cycle of ferns begins with the opening of numerous sporangium (sm) found on sori (so) which in turn are located on the undersides of specialized leaves. The sporangium (sm) release haploid spores (sp) into the environment. A spore is typically conveyed a short distance by wind, and upon landing can begin to germinate via mitoses into a multicellular prothallus. In Ceratopteris richardii, gametophytes have two genders (hermaphrodite, or males) and are visible via the light microscope. Located within the mature gametophyte (mg), archegonia (ar) produce eggs and antheridium (an) produce sperm, both mitotically. Fern sperm are flagellated, and thus require water in order to fuse with the egg in the archegonium, resulting in diploid zygote (zy) formation. Zygotes execute mitosis to become sporophytes. Once the young sporophyte (ys) develops, it will then be able to photosynthesize into a mature sporophyte (ms) again.
Previous works found that antibiotics inhibit peptidoglycan growth in species from phyla such as Lycophyta and Bryophyta. We intend to test whether ampicillin is also toxic to Ceratopteris richardii gametophyte as well as sporophyte development in future experiments.

Title: Evaluation of Common, Acrylic Chemical Bonding Agents as Phytotoxins of Gametophyte Development in the Fern, Ceratopteris richardii Abstract: What counts as toxic to a particular biological species may be entirely non-toxic to another. Acrylic bonding agents (ABs) are commonly used in numerous industrial applications. In liquid form, ABs have been shown to be exceptionally harmful in many different animal studies, including humans. ABs have not been fully investigated in plants. A contrasting example is silicone, used in clinical settings as bonding agents. Silicone exhibits no toxicity profile in humans, and like ABs, silicone toxicity in plants is also not fully investigated. All plants execute a lifecycle of alternating generations. However, ferns are unique because they possess freeliving gametophyte and sporophyte stages. Ferns allow us to not only test whether certain chemicals are phytotoxic, but also if these chemicals are specifically toxic against gametophytes and/or sporophytes.

Pancreatic cancer can develop in both exocrine & neuroendocrine cells, with exocrine types as the most abundant albeit poorer prognoses. Mutations in different genes can lead to pancreatic cancer, including in KRAS, TP53, CDKN2A, and SMAD4. Approximately 22% of pancreatic cancer cases involve mutations in these four genes alone. Traditional treatments for pancreatic cancer involve surgical removal of the tumor and use of chemotherapy treatment. Despite these treatments, the survival rate is very low, and it has not climbed significantly in the past several decades. We computationally identified a neoantigen expressed in a frameshifted SMAD4 allele of pancreatic cancer. This neoantigen is not found in any other human protein, and thus could be considered a foreign epitope by host T-cell responses, many of which possess anti-tumor activities. Our resulting mRNA vaccine design is precisely tailored to only individuals harboring somatic mutations in this SMAD4 allele.
The prevalence of diagnosing pancreatic cancer in later stages combined with the poor prognosis for patients diagnosed with nonlocal pancreatic cancer creates a low overall 5-year survival rate of 10.8%. This rate is very low, and the death rate has not fallen since 1975. There is a need for a new treatment that can treat cancer which has metastasized.

Stages of Pancreatic Cancer
Pancreatic cancer is most frequently diagnosed in the later stages. These are the stages where the tumor has spread into other parts of the body. Cancer that has spread away from the original site is particularly difficult to treat with traditional treatments. This is reflected in the 5-year survival rates of patients. Cancer discovered in later stages has significantly lower survival rates.
Pancreatic cancer is associated with mutations in different genes. Cancerous cells most commonly have mutant KRAS, TP53, CDKN2A, and SMAD4 genes. The proposed treatment requires a frameshift mutation. There are not frameshifts found in the KRAS gene, and other students are researching the TP53 and CDKN2A genes. Therefore, this project focuses on frameshift mutations in the SMAD4.
SMAD4 Frameshift Allele
National Cancer Institute
The SMAD4 gene lives on the + strand of chromosome 18. There is a sequence of DNA on in this gene, beginning at the 51,065,488 position on chromosome 18, that reads:
Archive Ensembl Database
LQAALLLLLMDTWTLLEEIAFVWVNSPMSTGQKPLREQGCT 6. BlastP was used to search the entire human proteome for this neo-antigen. If this amino acid sequence were found in a different human protein, then the vaccine would be ineffective. However, the 41-mer that was created was completely unique to cancerous cells—no other human proteins have this sequence.
7. Emboss Backtranseq was used with human codon usage tables to work backwards and create an RNA sequence that codes for the neo-antigen.
GTTCTTCAAGCTGCCCT
8. This RNA sequence was substituted into the Moderna Covid-19 vaccine. They replaced the sequence that coded for the spike protein.
(mutant)
The coding information of this DNA is stored in triplets, as indicated by the highlights. As shown above, the mutated strand contains a completely new set of triplets. This codes for a completely different sequence of amino acids which is not found anywhere else in the human body. This new series of amino acids is called an onco-antigen, and it serves as an identifier because it is unique to cancerous cells.
Body of the Vaccine – This RNA sequence codes for the amino acid sequence of the onco-antigen. Stop Sequence - This 9-letter sequence contains 3 codons— UGA, UAA, and UAG. These codons all signal to stop translation. The second two are redundancies to ensure that translation stops. 3’ UTR – This is the section of RNA that does not get translated into the amino acid sequence. Poly-A Tail – This is a repeated series of adenines that is added to the end of an mRNA sequence.
3. The DNA sequence was copied down, and the mutation was manually performed. 4. Expasy translate was used to translate both the wild type and the mutant into the amino acid sequence using the human codon translation table. 5. The mutant amino acid sequence looked identical to the wild type (normal) sequence until the mutation. The mutant continued for 41 unique amino acids before reaching a stop codon. This 41-mer is called the neo-antigen (or onco-antigen).
GTTCCTTCAAGCTGCCCT (normal)
A 1 base-pair frameshift can occur when a cytosine (51,065,491) is deleted from SMAD4. The new gene reads:
5’ UTR – This is the section of RNA that facilitates translation but does not get translated itself into the amino acid sequence. Start Codon – This is the sequence that signals the beginning of translation. It codes for methionine which is the first amino acid in the polypeptide.
1. The Cancer Genome Atlas (TCGA) was used to discover which mutations were caused be frameshift. This data base gives the specific location (chromosome, gene, and allele) of the mutation. 2. Ensembl Archive was used to find the DNA sequence of the wild type (normal) allele.
9. This RNA sequence is put into lipid nanoparticles and put into a vaccine.
RNA
Future Work This method of vaccine development shows potential applicability to a many different types of cancer, and it allows for treatments that are individualized to the patient. This research merits further examination in laboratory studies and clinical trials. A second goal for this research project is to develop bioinformatics tools or scripts that can generate RNA sequences directly from an inputted frameshift mutation. If this method of vaccination is shown to be effective in human trials, then programming tools will be necessary for this to become a viable and efficient treatment method for a wide variety of mutations and genes.

Abstract
Platform Capabilities
The purpose of this project is to design and create a flight simulation platform that is compatible with the Microsoft Flight Simulator 2020 software. The objective is to design the frame in a stable and safe way as to create a realistic alternative to an actual airplane for the user to experience as close to the real forces and motion as possible. In the future, this project aims to get the flight simulation platform certified, which would allow users to gain experience on the platform to help in an acquisition of a pilot’s license in a much more affordable manner.

Design
The operators of this simulator will be immersed in a flight environment using a virtual reality headset. There will be several physical controls for the operator to interact with in order to control the simulator. A yoke will be present to control the pitch and roll, pedals will be attached to control the yaw, and finally a throttle lever will be installed to control the power within the simulation.
It was decided that the seating frame would be made of extruded aluminum and bolted to the steel platform. The aluminum was anodized to prevent galvanic corrosion of both the platform and frame. The flight simulator platform is shown in Figure 3. The main frame shown in Figure 2, is made of 3in x 3in aluminum beams. The software for the simulation is Microsoft Flight Simulator. The control system, a yoke and pedals, will be made adjustable for ease of use for people of different heights.

Food Deser ts in Refugee Neighborhoods Hannah Lillie Analysis: This map shows the level of families in poverty by Erie block. The darker shade of the block indicates a high level families of poverty in that given area.
Analysis: You are able to see the areas that are highest in poverty levels by color. The darker the area the heavier the poverty rate.
Analysis: This map shows the big box grocery stores located within the Erie blocks. The zones of red and green mean the grocery stores are in walkable distance easily accessible for people in those areas. People who live in the purple shaded area are apart of the food desert
Abstract Food deserts in low-income areas have influenced the way Americans eat. Using GIS, the research spatially analyzes the accessibility of healthy food in refugee neighborhoods in Erie. The map identifies food deserts by comparing the data of poverty, residences of refugees, and location of food stores. Using poverty data from the US Census and location of food stores in Erie the research was able to identify the proximity of food desert areas from refugee neighborhoods. The research will support refugee organizations locating and establishing healthy food stores and live a healthy life.
Conclusion After analyzing the data collected using GIS, it is evidenced that there is a severe food desert located in Erie. Big box grocery stores are not as available in low income areas and areas where refugees have settled down in Erie. The residents who reside in these areas do not have easy access and commutes to these big box grocery stores. Unfortunately, this causes the community members who reside here to choose unhealthy processed foods from corner stores and fast food places. By comparing the maps, you are able to see the majority of the refugee population lives in the poverty hot spots. A major issue regarding the food desert located in Erie will result in the community members developing more health issues. To eventually minimize the health risks of the poverty and refugees, there should be more grocery stores with nutritious food more accessible throughout Erie.

The PCR test amplifies genetic material from the sample. If viral genetic material is present, a signal is produced using a fluorescent probe.
Since its discovery in December 2019, SARS-CoV-2 has been responsible for millions of deaths globally, and has been declared a worldwide pandemic. Similar to other RNA viruses, SARS-CoV-2 has an enhanced ability to mutate, resulting in the proliferation of several variants of concern (VOCs. The increased transmissibility, virulence, and decreased effectiveness of public health measures attributed to VOCs highlights the importance of genomic surveillance in tracing the spread of mutants and elucidating the emergence of novel variants. Gannon utilizes RT-qPCR and Next Generation Sequencing (NGS) to monitor prevalence of VOCs. The results of this study provide insight into viral evolution and the impact of SARS-CoV-2 VOCs within a university setting, leading to enhanced risk-aversion strategies at Gannon to mitigate the impact of emerging VOCs. Furthermore, these results illustrated the potential for localized genomic surveillance to reduce the burden of a public health crisis in similar industries and the general population.
Earlier signal (less cycles) = more viral genetic material. Compared to control standards to determine presence of the virus
To analyze variant characteristics of positive COVID samples, the TaqMan SARS-COV-2 Mutation Panel was utilized for qPCR runs. The qPCR run contained 4 mutation panels, the deletion at H69 and V70, D614G, L452R, and P681R. Presence of combinations of the mutations suggests specific variants, while unusual combinations requires sequence data for clarification. Generally, the delH69V70 would indicate Omicron, while the combination of L452R and P681R would indicate Delta. D614G should be expected in most if not all COVID positive samples The Ilumina MiSeq sequencer utilizing the NextClade program provided entire genomic sequence data of specific positive samples while also giving information on the phylogeny and mutagenicity of the samples.
Table 1. After comparing 2020-2021 data to the 2021-2022 athletics data, there are notable similarities between group types. The number of positive individuals remained about the same, whereas the percent positives increased, likely due to the decrease in overall athletic tests completed due to change in NCAA policies. As a result, we can infer that these trends for athletes are continuous, despite a reflective change in testing numbers. On the contrary, non-athlete status highlights health center tests and general surveillance. Despite seeing an increase in overall testing numbers within these categories, the results reflect higher trends of both number of positive cases and present positive cases.
Figure 6. The left graph indicates the percentage amount of each variant between August 2021 and January 2022. The graph reflects the Omicron 20K outbreak within the month of December, as the Delta concentration declines rapidly while Omicron surged, eventually completely taking over in January
Figure 7. The graph indicates the frequency of each individual mutation (shown in specified colors) between August 2021 to February 2022. The delta mutations were common during the Fall months, however, faded due to the takeover of Omicron. The delH69V70 mutation then surged with the Omicron spike. D614G remained the most common mutation and provided a comparison point

Eventually, 5 µL of this extracted RNA will be resuspended into 15 µL of PCR mixture in each well of the PCR plate.
Figure 4/Figure 5.The top graph shows the percentage of Gannon samples that are positive for that day, and the bottom reflects the number of positive cases each day. Noteworthy are the peaks within the graph around late December into early February. These results reflect periods of high infectivity and contagiousness within the population, suggesting possible seasonality and emphasizing a transition in variants. Despite an increase in testing numbers due to returning from winter break for the Spring 2022 semester, the number of positive cases still reflected an elevated positivity rate within the campus population

Host Genetics Susceptibility to Severe COVID-19 Disease
Amy Frosch Gary Vanderlaan, Ph.D. frosch001@gannon.edu
Interferon Signaling Pathway & Responses
Abstract Interferons (IFNs) are human proteins that slow down viral lifecycles by blocking host transcription and translation. Major histocompatibility complex (MHC) class I & II molecules are human proteins found on the surfaces of cells that help the immune system identify foreign peptide-based signatures. MHC molecules present peptide fragments on the cellular surface for recognition by T lymphocytes, and MHC class I is particularly important to activate cytotoxic T lymphocytes (CTLs) to kill virally-infected cells. Genome-wide association studies (GWAS) are used to detect correlations between genes, polymorphisms and diseases in a population. Several GWAS collectively reveal that both genes important in IFN signaling as well as certain MHC alleles act as host genetic risk factors for contracting severe COVID-19 disease. Such evidence strongly supports that infectious SARS-CoV-2 virions perturb host antiviral responses at the level of IFNs and CTLs.

SARS-CoV-2 Inhibition of IFN Pathways
Coronaviruses interact with the immune system in various ways. ORF3b, ORF6, nsp1, N, M, and Plpro are some SARS-CoV proteins that disrupts the host immune system. All of these proteins have a part of inhibiting the IFN pathway that discontinues the signaling pathway and response system of IFN. N proteins inhibit TRIM25 which limits the activation of RIG-I PRR, recognition of viral dsRNA. All of the SARS-CoV proteins block entry of IRF3 and IFN transcription. Nsp1 inhibits the activation of IRF7 and c-Jun expression. M and nsp1 both disrupt the activation of IFN by NF. ORF6 and nsp1 block STAT1 from translocation and phosphorylation. SARS-CoV ORF6 leads to an increase of viral replication within a cell.

Reported Data
Since the beginning of 2020, confirmed COVID-19 cases and deaths have been on the rise. Currently for the lower economic classes the confirmed cases of COVID-19 are over 400 million while COVID-19 deaths are about 6 million. The high and upper middle income have much lower numbers of confirmed cases and death. This is due to the availability and reliability to test these specific economic classes.
PlPro, nsp1, and ORF3b also target IRF3 phosphorylation while ORF3b and N further inhibit IRF3 translocation to the nucleus.

Title: Host Genetics Susceptibility to Severe COVID-19 Disease Abstract: Interferons (IFNs) are human proteins that slow down viral lifecycles by blocking host transcription and translation. Major histocompatibility complex (MHC) class I & II molecules are human proteins found on the surfaces of cells that help the immune system identify foreign peptide-based signatures. MHC molecules present peptide fragments on the cellular surface for recognition by T lymphocytes, and MHC class I is particularly important to activate cytotoxic T lymphocytes (CTLs) to kill virally-infected cells. Genomewide association studies (GWAS) are used to detect correlations between genes, polymorphisms, and diseases in a population. Several GWAS collectively reveal that both genes are important in IFN signaling as well as certain MHC alleles act as host genetic risk factors for contracting severe COVID-19 disease. Such evidence strongly supports that infectious SARS-CoV-2 virions perturb host antiviral responses at the level of IFNs and CTLs.

Identification of orthologous genes in ferns that are implicated in the development of moss rhizoids and cress root hairs. Introduction
Timothy Edwards John Vieira Jenna Sins Dr. Gary Vanderlaan Dr. Mike Ganger edwards096@gannon.edu
Bioinformatics Methodology: tBLASTn
Transcriptome Assembly: Mapping Reads Laboratory: Data Collection
• Plants go through diploid sporophyte stages and haploid gametophyte stages • Some plants develop sporophyte root systems, others develop gametophyte rhizoids, but ferns maintain both functional roots and rhizoids. • Genes that generate rhizoids only and genes that generate root hairs only are both well studied. This project examines fern genes that can generate both root hairs and rhizoids.
The tBLASTn method aligns peptide sequences. As such, the algorithm tolerates synonymous mutations (i.e. of redundancy in the genetic code). Over evolutionary time, as nucleic acids change, conserved protein domains and motifs of essential processes remain constant at the amino acid level.
Messenger RNA is extracted from fern cells and fed into a sequencer. The sequencer produces a fastQ file which stores the nucleotide sequence as well as the quality of each data point.
mRNA
Putative fern orthologous genes
Land plants are embryophytes that descended with modification from an ancestral charophyte. Bryophytes are non-vascular plants with a dominant gametophyte life-cycle stage. All Bryophytes rely on haploid rhizoids for nutrient assimilation. Vascular plants in contrast exhibit a sporophyte-dominated life-cycle, and all vascular plants contain lignified tissue that permits xylem and phloem to conduct water and food, respectively. Some vascular plants are seedless (e.g. ferns of Monilophyta) while others evolved seeds (e.g. gymnosperms and angiosperms). The flowering plants (angiosperms) lack rhizoids and assimilate nutrients via diploid root hairs. Ferns are a transition organism: gametophyte-stage ferns are bryophyte-like and have rhizoids; sporophyte-stage ferns are angiosperm-like with root hairs.
fastQ Sequencing data stored in the fastQ file is used to assemble a de novo transcriptome. This is done in the Galaxy linux environment on a software called Trinity

All plant lifecycles execute alternation of generations. Briefly, a haploid spore germinates into a multicellular gametophyte. Flagellated sperm fertilize eggs in archegonial chambers found on gametophytes to form a diploid zygote. Mitoses yield a mature, diploid sporophyte capable of producing haploid spores via meiosis. Ferns are uniquely capable of producing both haploid rhizoids during gametophyte stages and diploid root hairs as sporophytes.

tBLASTn results are shown using known genes (as ptn queries) for root hair development in the angiosperm, Arabidopsis thaliana against existing sporophyte and gametophyte transcriptome databases (as 6-ORF predicated peptides). Our search yields ~25 fern orthologues (not all are shown above) with e-values < 10-10 significance.
Second Generation Sequencing, also called Next Generation Sequencing (NGS) is an extremely efficient method of sequencing nucleic acids. This method has drastically reduced the price of sequencing and the time that reads take. It can simultaneously read many fragments at the same time which dramatically increases the number of nucleotides that can be processed. This process can be used to build complete transcriptomes or genomes.
Title: Identification of Orthologous Genes in Ferns that are Implicated in the Development of Moss Rhizoids and Cress Root Hair Development Abstract: All land plants alternate generations between a haploid gametophyte and a diploid sporophyte stage. However, the significance of each generation varies across clades. For instance, many mosses are gametophyte-dominant and produce gametophyte structures known as rhizoids to absorb nutrients. Moss sporophytes are small and lack roots. In contrast, many flowering plants have sporophyte-dominant stages that rely on root systems for nutrient absorption and don’t produce any gametophytic rhizoids. Between these two classes lies Ceratopteris richardii, a fern capable of producing both gametophyte rhizoids and sporophyte root systems. The genes in flowering plants that produce sporophyte root hairs and genes in mosses that develop rhizoids are well studied, but little is known of the specific genes utilized in ferns for similar processes. Here we showcase novel fern genes that are expressed in gametophyte and sporophyte stages that relate to known moss and cress genes that are important for rhizoid and root hair development, respectively.

Title: Innovative Archery Stabilizer Abstract: The research conducted is aimed at developing a dual archery stabilizer that increases shot accuracy while reducing torque and vibration throughout the bow. The mechanical design has a goal of creating a stabilizer that is 10 inches long but provides similar stabilization to a 36-inch competition stabilizer. The stabilizer consists of a screw mount, body shell, dampening material, and weights. Three brands of bows (Prime, Athens and Matthews) were tested in the field using an accelerometer to test each of their natural frequencies. Each of these three bows were first tested without a stabilizer. A trophy ridge, viper, and a viper competition stabilizer were then placed on all three bows to generate an average data collection of dual archery stabilizers made by competitors to be compared to a newly developed prototype. The goal of our product is to increase archery hunters’ shot accuracy without the inconvenience of an extra-long stabilizer.

Lavery Keg Lifter
Current Method For Cleaning Kegs
Our Design/Customer needs
• A research group of OT students led by Dr.Lavery identified that the ergonomics behind cleaning kegs is hazardous to employees. • The current method of cleaning a keg is an employee lifting a keg 52 inches high and 19 inches away from their body.
• Able to lift and rotate kegs onto the cleaning system as well as transport and stack full kegs • Device to be easy and quick to use • The device also needs to be ergonomically designed so that it can be used by a wide variety of people • Easily moved around and maneuvered in a wide variety of environments.
Joseph Molea Ivan Stapchuck Mackenzie Hewitt
Existing Solutions • Solutions to lifting kegs do exist • Most keg lifters do not rotate, the ones that do are very expensive • Current keg lifters are too expensive (easy lift equipment co. $16,000, cooler concepts $3,000, Glacier Designs discontinued

Title: Lavery Keg Lifter Abstract: Our goal is to design a multi-purpose device that is capable of lifting and rotating kegs for cleaning in order to reduce the likelihood of injury as well as provide a budget-oriented solution. A research group led by Dr. Lavery has identified that the action of lifting and lowering kegs manually during the cleaning process can be detrimental to the employees’ health. Our solution aims to eliminate the risks associated with this process. This device is going to be used in a brewery or in related fields that need to lift and flip larger cylindrical objects. In our case, the customer would like a device that lifts kegs to be cleaned. It does not only have to be able to lift them up but also flips them upside down to be placed onto a spigot that cleans them.

Macro-Litter in Urban Stormwater: Levels and Contributing Factors Susannah Harris, Kristen Heflin, Dr. Varun Kasaraneni Department of Environmental Science and Engineering
Background
Methods
Results
After sample collection, the strainers were set aside for 5 days. This was a safety measure to prevent any transmission of harmful bacteria or viruses, and allowed for the sample to dry. After the five days, the sample was removed from the strainers, placed on metal trays, and spread out in a thin layer. To ensure all sample material was removed from the strainer, each was thoroughly cleaned with a dry coarse brush. Once on the trays, the large pieces of material (leaves, large plastics like used water bottles, cigarette butts, etc.) were removed. Each of the leaves and large pieces of material were cleaned over a 300 µm sieve, to ensure that no microplastics were discarded. The sieved materials within the microplastics range (300 µm to 5mm) were set aside for future further analysis. All litter greater than 5mm was categorized according to an adapted version of the EPA classification system, counted, and weighed.
Marine litter is a persistent and ubiquitous concern. Litter impacts wildlife, habitats, navigation, economics, and health and safety of both marine and human life. This issue must be addressed in the form of education and prevention, while also managing and removing the existing marine debris. A major source of marine debris is transported through stormwater. Robert Jonsson defines stormwater as “runoff generated from rain or snow that flows over land or impervious surfaces to recipient water bodies, either directly or via culverts, gutters, swales, or ditches” (Jonsson 2017). Stormwater is an issue that becomes more prominent as urbanization increases. This is problematic because stormwater carries pollutants into water bodies. Pollutants from stormwater commonly include heavy metals, oils and other organic chemicals, eutrophication-causing nutrients, and garbage (Jonsson 2017).

Figure 1. Storm drain at Peach St. & W. 25th St. Stormwater is one of the largest causes of litter entering waterways. As climate change progresses, the problem of litter becomes larger. Many countries are projected to receive an increase in precipitation events, increasing the deposition of litter into waterways. The accumulation of plastics in waterways can be partially attributed to combined sewer overflows, out-of-date but common sewage systems, which combine both sewage and wastewater. Stormwater has the ability to pick up garbage from surrounding areas, enter the overflows, and go directly into bodies of water (Jonsson 2017).

Title: Magnetorheological Fluid Knee Brace Abstract: Knee buckling is a condition where the knee joint slips and causes sudden pain and potentially a fall. It affects nearly 12% of adults between the ages of 36 – 94 with the most common causes being arthritis, torn ligaments, kneecap dislocation, and inflammation (Beacon, 2022). For some it may just be a small annoyance but for others it can be a serious health hazard, especially for the elderly. Falls in the elderly population has a direct impact on the day-to-day operation and immobility can quickly degenerate into permanent disability or death. There are available knee braces on the market, but a selected few have the capability to stop buckling while still providing adequate support for the knee. The goal of this project is to design a knee brace that stops buckling by utilizing a magnetorheological fluid, a smart fluid that, when in the presence of a magnetic field, increases viscosity.

Title: Manfacturing and Mechanical Testing of Porous Osteoconductive Scaffolds Abstract: Osteoconductive scaffolds play a crucial role in synthetic bone grafts as they can promote attachment of cells and stimulate cell growth on the scaffold. To achieve tissue regeneration, scaffolds are implemented in the human body, higher porosity facilitates this process. However, the relationship between porosity and strength is a core principle in osteoconductive scaffolds. Through a CAD design process, additive manufacturing, and mechanical testing of the specimens the effect of porosity and pore shape on osteoconductive scaffolds was assessed. 1inch by 1inch cubes with varying porosities of 60 percent, 70 percent, and 80 percent and square shaped pores were tested. The specimens were designed using Creo Parametric, a computer-aided design software, printed using Prusa 3D Printers, and tested under compression with MTI-2k Universal Testing System. The hypothesis of specimens with 60 percent porosity and square shaped pores would have the strongest mechanical properties was assessed.

Model of Continuous Systems with Discontinuity Peter Caulfield, Dr. Pezhman Hassanpour Department of Mechanical Engineering, Gannon University
Background
Novel Method
Application
Analytical mathematical models are critical to understanding the fundamental characteristics of dynamical systems, allowing for a relatively simple examination of the effect of each parameter on the overall system. Such models generally account for various types of inputs to the system via external forces or boundary conditions and give the response of each degree of freedom (DOF) over time. For structural systems, these models can be developed by applying Newton’s 2nd Law of Motion for each linear DOF and Euler’s Law for each rotational DOF.
In this work a means is devised to solve this PDEs and generate a model of systems with discontinuities. This means hinges on the use of jump conditions in the region of the discontinuity.
As an example, this method will be used to solve the case of a thin string with an attached point mass under an axial load (Figure 1).
Jump conditions are so named because they account for the jump in input that a discontinuity causes. They do this by integrating the governing equation in an infinitesimal region surrounding the discontinuity. This gives the sudden change in one of the governing parameters across the discontinuity (e.g., the change in slope of the string).
For continuous systems, which contain an infinite number of DOFs, these laws can be applied on a differential basis, forming partial differential equations (PDEs). PDEs are complex, requiring the use of ingenuous methods to solve.
The jump condition is used in conjunction with the standard methods to solve the complete problem. The general process is as follows. First the governing equation is developed using, e.g., Newton’s Law, where the discontinuity is modelled using a function such as the Dirac delta or the step function. The system is then separated at the discontinuity into two continuous regions, in each of which the governing equation can be solved using separation of variables. These solutions include several unknown coefficients, which can be solved for using boundary conditions, continuity conditions, and jump conditions. The last two types allow the two separate solutions to be stitched together into a cohesive whole.
Well-behaved, homogeneous geometries are not overly difficult to model, with the governing PDE being solvable using the method of separation of variables. However, this method is impossible when the system contains discontinuities. These discontinuities are common in engineering applications, though: e.g., a beam with a step in the cross-section, a string with an attached mass, and many others. Hence discontinuous systems must be analyzed in a different way.
Figure 1. Schematic of example showing length L and density ρ of string, mass m and location a of attached inertia, and axial force P.
Applying Newton’s Law to a differential element yields (1) where w is the displacement of the string from its equilibrium position. Converting this to a dimensionless form to simplify and applying separation of variables gives (2) Here Ω is a dimensionless form of the natural frequency of the string, while μ is a dimensionless mass. This is a simple ordinary differential equation, the solution of which (around the discontinuity) is (3) The four constants involved require four conditions to find: one continuity, two boundary, and one jump. The first simply states that the string does not break at the point where the mass is attached, the second pair that the string is fixed at its ends, and the last providing the change in angle of the string from the left side of the mass to the right.
Integrating the governing equation (Equation 2) in an infinitesimal region centered at the discontinuity to obtain the jump condition gives Note that the properties of the Dirac delta make the right-side integral very simple. On the left, the first term in the integrand becomes the first derivative of y (or the slope of the string), while the second is zero (the area under a differential element of the string is zero): In its final form, the jump condition is (4) Thus the change in slope is a function of the dimensionless mass and natural frequency. Combining all four conditions gives a way to solve for the constants in the solution (Equation 3) in terms of the governing parameters of the system:
Conclusion The method demonstrated here allows not only for solution of governing equations with one simple discontinuity, but also with more complicated scenarios containing many discontinuities by applying the jump condition at each. This is a powerful means to gain greater insight into the behavior of these complex systems.
Title: Model of Continuous Systems with Discontinuity Abstract: This work addresses the exact solution of a beam’s free vibrations with a concentrated mass within its intervals when the beam experiences axial loading, which problem is frequently encountered in the design and modeling of resonant microsensors. This approach determines the exact natural frequencies and mode shapes of the vibration using second-order boundary conditions for the beam. In so doing, each span of the beam is treated as an individual beam modeled using the Euler-Bernoulli beam model. A secondorder approximation is used to derive the boundary conditions and yields a set of partial differential equations, converted to a set of ordinary differential equations using the method of separation of variables. The derived eigenvectors and eigenvalues of this set are the system’s mode shapes and natural frequencies. This approach successfully obtains these results even when the compressive axial force approaches the critical axial force.

Genes Linked to Corpus Uteri Cancer
The uterus consists of four regions: the fundus, corpus, isthmus, and cervix. Uterine cancer can develop in these regions commonly as endometrial uterine cancer and rarely as uterine sarcoma. Uterine cancer accounts for 3.5% of all new cancer cases with approximately 3.1% of women being diagnosed with it in their lifetimes in the United States. The overall 5-year survival rate for uterine cancer is 81.1% with higher survival rates attributed to localized forms and lower survival rates associated with distant forms. The death rate for uterine cancer has remained stable between 4 and 5% for the past forty years. Existing treatments include surgery, radiation therapy, chemotherapy, and hormone therapy. Some genes associated with uterine cancer include: PTEN, PIK3CA, ARID1A, TP53, KMT2D, and CTCF. We designed a mRNA cancer vaccine as a potential treatment for uterine cancers associated with a specific frameshift allele of the CTCF gene.

While the rate of new cases of uterine cancer has fluctuated slightly over time, death rate has stayed relatively constant. With modern medicine and technology, more must be done to improve the survival rate of uterine cancer.
The above figure shows the process in which a cancer cell will use major histocompatibility complex I (MHC I) to display an antigen. We will create a vaccine which will allow cells of the immune system, such as cytotoxic T cells and natural killer cells, to recognize the antigen and launch an immune response to fight and kill the cancer cells that display it.
5’ UTR: This is an untranslated region which is critical for ribosome recruitment to the mRNA molecule. Ribosomes then bind to the molecule and initiate translation. AUG: This is a start codon. It specifies the methionine to begin translation of the message into a nascent polypeptide. ORF: This is the open reading frame of the mRNA molecule. It is the portion of a DNA molecule that, when translated into amino acids, contains no stop codons. STOP: These are stop codons, which terminate translation of the mRNA. Ribosome disassociates into subunits. 3’ UTR: This is another untranslated region which contains a polyA site. polyA tail: This is a long chain of adenine nucleotides that helps stabilize the molecule against cytosolic 3’ to 5’ riboexonucleases.

A Clean, Well-Lighted Place
Abstract
The Making of NIMBUS
100ft To prepare for a flight, sterilization of the payload canister must be completed to ensure axenic flight results. The canisters and each supporting piece are first thoroughly washed using 70% ethanol. The various NIMBUS parts are subsequently UV-sterilized in a standard eukaryotic cell culture hood. NIMBUS parts are further flipped every several hours to ensure all surfaces have received thorough UV treatment. UV irradiation at these intensities and durations is potently germicidal, overwhelming microbial DNA repair systems.

To ensure that our nutrient plates receive inoculum at precise altitudes, the payload canisters must be sealed axenically. Using magnetic seals on our lids, we tested three designs incorporating varying distances between standoffs, as the strength of magnetism dissipates at the d2 function. We estimate a max airflow velocity of ~37 mph that might wash over our drone during flight operations. We executed a stress test, exposing our payloads to ~40mph of airflow for ~5 minutes and checked for breach by contamination.

Canisters are extensively sterilized via an ethanol wash followed by overnight ultraviolet bombardment. Our canister lids utilize magnetic seals to prevent in-transit contamination, and upon arriving at altitudinal destinations, a servo-motor breaches magnetic seals to permit ambient exposure to payload media. Our current experimental design will collect aerial samples in 100-foot altitudinal increments, up to a 400-foot ceiling per FAA regulations. Retrieved payload media will be incubated in aerobic and anaerobic conditions, followed by DNA extractions of cultured microbes for species identification via 16S rDNA (bacterial) or ITS (fungal) profiling.

Traditional biosignature gases, are gases that accumulate in Earth’s atmosphere in a fashion primarily driven by living entities. Biosignature gases are particularly important to astrobiologists in their search for evidence of life on other planets. On Earth, phosphine (PH3) gas is produced primarily by human or of PH3 in the atmosphere of Venus. Such PH3 concentrations suggest the possibility of microbial life on our sister planet. On Earth, microbes are masterfully ubiquitous. They broadly occupy numerous ecological niches, via their impressive metabolic diversities. If microbes truly do occupy the Venusian clouds, can we say the same of our very own skyline?

We plan to operate our drone at 100ft altitudinal increments carrying our payload canister comprising six nutrient media types. The payload is designed to select for different microbes to be cultivated from air samples of differing altitudes. We hope to sample eventually the aerobiomes of urban, rural, and lake systems in the nearby region.

A hexacopter drone [1] was assembled in order to fly a sampling device mounted on top [2]. The sampling canister [3], designed in Autodesk Fusion 360, consists of lids that open to expose the sampling equipment inside to the environment in order to collect data. The lids will open only at the precise height of sampling via radio commands. The tower [4] secures six petri dishes to sample environmental microbes, and is placed inside the canister [5].

As our 1mm canister design proved axenic in the prior airflow stress test, we next needed a servo that can breach the magnetic seal when the drone reaches a target altitude.

Non-Opioid Alternatives to Pain Relief
Introduction: The United States has masked chronic pain with the use of opioids for over a century. With the issue coming to light over the past few decades (NIH, 2022), scientists and health care workers have found alternatives to opioid consumption that can be much safer, better for your body, and help to minimize pain (Kaye, et. al., 2020). Background Information:
“Endorphins muffle your perception of pain and boost feelings of pleasure, creating a temporary but powerful sense of well-being” (Mayo Clinic Staff, 2018). Why use alternatives?
• The opioid crisiso The opioid epidemic is a crisis affecting the United States; its severity accounted for about 50,000 deaths in 2019 alone. o Addiction and dependence on opioids due to misuse, lead to other issues dealing with mental and physical health. o The use of opioids has become a huge economic burden on society (NIH, 2021). o Our society is lacking in knowledge of opioids. ▪ There are information deficits on inappropriate and appropriate prescribing methods, drug legislation, and modern-day research on opioids (Dydyk, 2022). • Branching away from controlled substanceso We need a relief mechanism, that is not harmful, to manage excruciating pain. o Health scientists have been working towards finding alternatives to opioids that are more sustainable and better for the body. o For many years treatment of chronic pain included rest and inactivity (Kaye, et. al., 2020). o Health care workers know much more about the effect that inactivity can have on your health when suffering chronic pain. o Early mobilization is better for recovery (Kaye, et. al., 2020). o Specific non-opioid alternatives that focus on health, movement, and mind and body connections are physical therapy and yoga o Evidence suggests that there should not be a singular technique used for pain relief (Dydyk, 2022).
o This means that opioids should not be a standalone treatment, and based on gaining research and traction of alternatives, opioids are not seen as the safest of a choice (NIH, 2021).
Figure 1 (left): Opioid epidemic by the numbers (Assistant Secretary of Public Affairs (ASPA), 2021)
1) Opioids are very addictive, expensive for society, overall bad for your health o How are they addictive?▪ When taking opioids, endorphins are released by your brain. ▪ “Endorphins muffle your perception of pain and boost feelings of pleasure, creating a temporary but powerful sense of well-being” (Mayo Clinic Staff, 2018). ▪ Once these feelings wear off, some people are left wanting more feel-good neurotransmitters (Mayo Clinic Staff, 2018). ▪ A person is addicted when they crave taking opioids or when they yearn for those same feeling’s opioids give them. o The economic burden of opioids▪ The U.S. spends over 100 billion a year on opioid-related costs (Dydyk, 2022 and NIH, 2021). ▪ Factors into this cost include, cost of health care, decrease in productivity, treatment of addiction, pain management, opioid dependence, and law force involvement (Dydyk, 2022 and NIH, 2021) o If misused, they can be bad for a person’s overall health▪ People have trouble thinking properly and clearly under the influence of drugs ▪ Issues like behavior and emotional problems affected many of those who are addicted (NIH, 2021)
Elizabeth Walker Walker072@gannon.edu
o Physical therapy▪ The use of this method constitutes both manual therapy and an exercise-based approach to recovery. ▪ The Journal of Physical Therapy Science found that these methods are effective with pain reduction and disabilities. ▪ Sacroiliac joint dysfunction and treatment of low back pain have been tested and it was proven true that therapy can help (Kaye, et. al., 2020). ▪ It can be used as a preventative measure (preventive analgesic treatment) • Evidence from tissue damage-induced surgical studies suggests that Pre-emptive analgesia reduced postoperative pain. • It also reduces the consumption of pain medicines post-surgery (Vadivelu, et. al., 2014). This means that fewer opioids would be consumed, giving the consumer less of a chance to become addicted. • Types of Pre-emptive analgesia are light exercise, fall prevention therapy, yoga, etc.
o Yoga▪ Yoga is the physical and spiritual use of your body and mind that creates an interconnectedness between the two. ▪ 2016 literature investigating yoga found that it can be used to reduce chronic low back pain. ▪ Patients with knee osteoarthritis who did yoga reported that while using this practice, they had reduced pains and their mobility was increased. ▪ A 2017 study found that using a Hatha style of yoga chronic pelvic pain may be reduced and patient quality of life was also increased. ▪ In 2015, arthritis Patients were tested, and trials revealed that patients who went to yoga classes increased physical activity and health (Kaye, et. al., 2020). ▪ Yoga has shown to improve multiple aspects related to overall health, but also reduce multiple different types of pain.

2) The alternatives give a holistic approach to overall health o The holistic approach to healthcare utilizes your whole being, which includes mind, body, and spirit to maximize the impact different treatments can have on you (Boelman, et. al., 2021). o The target of opioid use is not always helpful when recovering from pain ▪ For example, it has been shown that opioid use before surgery can impact you negatively during recovery (Goplen, et. al., 2019).

Title: Non-Opioid Alternatives to Pain Relief Abstract: The opioid epidemic is a crisis affecting the United States; its severity accounted for about 50,000 deaths in 2019 alone (NIH-National Institute on Drug Abuse, 2021). As a society that does strenuous activities, gets hurt, has surgeries, ages, and overall feels pain, we needed a relief mechanism to manage excruciating pain. Health scientists have been working towards finding alternatives to opioids that are more sustainable and better for your body. Some specific alternatives that I will focus on in my argument include physical therapy, yoga, and exercise.

Nonplanar 3D Printing Attachment
Evan Mihalko (M.E) Sauod Ahlilal (M.E)
Problem Statement Currently, traditional 3D printers build desired objects by placing individual layers across the entire part. These layers stack on top of one another until the part is complete. The problem with this form of additive manufacturing is that it requires the use of support material for overhangs along with an undesirable staircasing effect.
How Does it Attach?
Abstract
-
- To design and build an attachable additive manufacturing print head nozzle Attachment functions in the X, Y, and Z planes simultaneously while a motor provides an axis of rotation separate to the printer - Capable of printing overhangs with no support material and the elimination of the staircasing effect found in traditional 3D printing.
- Finished parts lack strength along the direction of the layers - Contain suboptimal surface finishes - Require post processing to improve product
By removing the nozzle of the existing printer and using this attachment, the functionality is lost but provides structural backbone to the chosen design.
Design
This staircasing effect can negatively impact the finished product in the following ways: M6x1 Threaded Screw
The attachment uses a currently existing traditional 3D printer, PRUSA i3 Mk3S, as a supporting mount. By doing this, the code to run the printer is readily available and capable of being modified.
3D Printed Mounting Piece
For this reason, traditional 3D printing makes objects containing smooth curves nearly impossible to create accurately. The stair casing effect can be seen below.

Nonplanar 3D printing combines the motion of the X, Y, and Z axis, allowing for smooth curved objects to made with high quality. Check out how the layers of this airplane wing are placed.
Figure 3: Nonplanar 3D Attachment Schematic
• By running the motor and extruder independently of the PRUSA print head, the added rotation allows for an additional degree-of-freedom within the printer and is combined with the X, Y, and Z motion. • The extruder is placed at a 45-degree angle relative to the print bed. This angle provides maximum room for laying part material without contacting the print head or part. • To melt PLA the extruder reaches temperatures upwards of 250 degrees Celsius. To cool this, a 12 Volt fan is used and mounted to blow air across the extruder fins shown in Figure 4. • To control the motion of the DC Stepper Motor, an Arduino can be used. • The combination of these parts results in an object that can be 3D printed as shown in Figure 2 with smooth edges and a minimized staircasing effect.

Title: Non-Planar 3D Printing Attachment Abstract: The objective of this project is to design and build an attachable additive manufacturing print head nozzle capable of providing the necessary versatility required for non-planar 3D printing technology. Currently, traditional 3D printers make parts by placing one entire layer of material onto the bed and then repeating this process until the part is made. With the Non-Planar 3D printing attachment, the printer will be able to move simultaneously in all directions, allowing for unique shapes and designs to be made. Typically, arches and overhangs require the use of support material but by creating rotational motion separate from the printers standard motion, this support material can be eliminated.

Research Topics
Abstract • Research is essential to continue the growth and evolution of an ever-changing society. It is often thought that undergraduate students lack the skills and knowledge needed to perform research. College is a tool that allows students to gain background knowledge that will be beneficial in the workforce, however students are battling boredom in the classroom due to the lack of hands-on experience. Using topics taught in class, such as ergonomics and work design, a student was able to develop research questions that interested her. By doing background research and field studies, the student went through the process of creating an IRB and developing a survey. This presentation will explore the benefits of undergraduate research by using a personal story of how a college student connected her love of horses and her studies of ergonomics to create life changing opportunities.
Background
Ridden horses for over 10 years, a large part of my life before college
• I started with doing an investigative visit of a local farm. I took tons of notes that all were complied into a massive excel sheet.
• Through this excel sheet I created 5 main topics: 1. Effect of Frequent Job Turnover on Equestrian and Horse Safety 2. Tractor Safety and User Age 3. Demographic Factors effecting Job-Related Injuries of Equestrian Workers 4. Environmental Factors’ Influence on Horse Safety in Barns 5. Barn Chores and Cumulative Trauma Disorders
Tractor Safety and User Age • • • •
• Summer of 2021, I decided I wanted to start doing research • Contacted Dr. Ohu and he encouraged me to choose my own area of study • Googled “industrial engineering and horses”
I wanted to write a paper for a conference that my abstract had been accepted too. Gathered articles and information around the topic Quickly learned there is not a lot of data around this issue Found: • 50% of all tractor accidents are rollovers • Agriculture is the second most dangerous industry under construction • Very little safety standards in place for agriculture
Current Research • Cumulative Trauma Disorders • Repetitive motion injuries that cause chronic pain • Tennis Elbow, Tendentious, Trigger Finger • I wanted to explore is CTD’s occurred in horse farm workers • Created a survey to gather baseline data • Used my observations to make questions
• Got 569 responses to the survey • Shows a backing for the research • I received many personal stories regarding how chronic pain has occurred from working with horses
Personal Story “When I started lugging the muck tubs to the spreader and lifting them overhead to dump them in the spreader, my upper back pain from arthritis started again. This led to the revelation that most of my upper back problems were coming from dumping muck tubs. I have since changed my routine. Now I park our tractor with high lift bucket in front of the barn with the bucket lowered to the ground, and I drag the tubs to it to dump (no overhead lifting!). I use the tractor bucket to dump into the spreader. While my arthritis will never truly go away, I have been able to manage it by making this easy change.”
Conclusion
• Learned: • • •
I had fun writing a paper! Learned a new style of writing Enjoyed research and found a way to bring horses back into my life
• I learned how to make school fun for me and found a way to connect horses to learning experience • I created a survey that got over 569 responses • Become more confident and opened new doors to my learning experience

Body tech is a year round project that is developing the Proof By evidence/ (PBE) device. The purpose of the PBE device is to allow any user to autonomously alert close family members or friends that you have fallen in the probably of how sever the situation may be. This will give the user chance to call for help when they are in dyer need.
Title: Fall Detection System Abstract: The Primary focus of PBE tech is to deliver mobile support when under attack or if one has fallen or pushed to the ground. During such circumstances, the PBE tech device will save the status of the situation through a mobile app on your phone. The mobile app will then send it to a cloud server database. The status includes the event, time, and location. After the status is saved, it can be repurposed to provide evidence in court or in a company. In the first initial fall, attack, or push, the mobile app will notify close relatives through text and allow them to respond quickly to a potential serious situation. The PBE tech team’s goal is to provide security and justice for individuals who live there day to day lives, factories who want to keep their employees safe, and for those who like to adventure outdoors.

Pinch Meter Ruba Alshaeri, Bader Alhilal, Alexander Headley Biomedical Engineering Program ,Gannon University, Erie, PA, 16541
Background
Methods
Material
Currently, there is no specific pinch meter that can isolate the flexion force exerted by the first phalanx of the thumb. The device will help determine the progress of recovery of the anterior interosseous nerve after surgery. The physician will be able to assess the flexion force applied from the interphalangeal joint of the thumb to the device before the surgery and compare it to the force applied to the device after the surgery. Having a device that could easily measure the flexion force of the interphalangeal joint of the thumb, will ensure better objective feedback of post surgical data and could help in the diagnosis of compression neuropathy of the anterior interosseous nerve.
At first, we did some research about different springs and their maximum loads. The spring we chose for our device can hold up to 20.2 pounds which is reasonable for force applied from the interphalangeal joint of the thumb to the spring. Then, we had to finalize our design and get it approved by the Orthopedic Surgeon at UPMC. The drawing for the device itself is shown in Figure 1. The CREO design for the device is shown in Figure 2.
All the outer parts of the device will be 3D printed using one of the 3D printers provided by the the university. The printing material used will be PLA. PLA stands for Polylactic Acid which is a type of plastic. This material is tough and excellent for building models and pretotypes of solid objects. Also, the material is a thermoplastic polymer. The measurement of the force exerted will be measured by spring that can hold up to 20.2 pounds. The spring used in this device is Music Wire Steel which is made of high tempered carbon steel its dimensions are 11.21, 1.25, 64 mm for outer diameter, wire diameter, and full-length length, respectively. The material used for the slide scale will be PLA as well which would control the movement of the spring and make it more stable. For the hand strap prototype, it will be a modified wrist brace.
We chose this project is because UPMC came to us and asked if we could develop a device that could measure the strength in the thumb both before and after a carpal tunnel repair surgery to ensure that the surgery was successful. Currently, their testing method does not involve a device at all, they conduct their test by just having the patient push on the hand of the attending physician. Their main concern is the isolation of the first phalange of the thumb so that they are not using other muscles in the hand to aid in the test. Significance: Our main objective for this project is to measure only the flexion force exerts from the first phalanx of the thumb in the most neutral position. In this project, the device must only read the force exerted from thumb's interphalangeal joint which force is mostly dependent upon the flexor pollicis longus muscle while ensuring that other muscles in the hand are not affecting the reading. Additionally, the device will not apply force back to the interphalangeal joint of the thumb. Furthermore, the device’s length will be easily adjustable to suit most if not all size of hands. There are many engineering characteristics that must be put in consideration while finalizing the design such as the force sensitive resistor, weight of the device, and accuracy. This is a collaboration between Gannon University Biomedical Industrial and Systems engineering department and the Orthopedic Surgery program at UPMC. We look forward to deploying the device for the acquisition of normative data.
Future work - Modify the design to obtain more accurate results. - Use different a spring that could hold more strength for different genders, and ages. - Use digital screen instead of spring-based device. Figure 1: The drawing of the device with its dimensions.
- Use different material for the hand strap that could fix the movement of the hands.

Title: Pinch Meter Abstract: Our group project is the Pinch-Meter which is a medical device that is used as a diagnostic and assessment tool. The main problem we noticed is that most of the Pinch meter devices available in the market cannot isolate the single movement in the interphalangeal joint of the thumb which could affect the accuracy of the readings of the pinch meter. Our main objective for this project is to measure only the force exerts from the first phalanx of the thumb in the most neutral position. Additionally, the device will not apply force back to the interphalangeal joint of the thumb. There are many engineering characteristics that must be put in consideration while finalizing the design such as the force sensitive resistor, weight of the device, and accuracy. For this device, the specific requirements and standards must be met since it is considered as a medical device. The device will require little to no training to use. The device will only need basic cleaning such as alcohol wipes.

Abstract
There is no doubt that COVID-19 has changed our way of life. With over 12 million US child COVID-19 cases some daycares are stepping up to help reduce the transmission. To reduce the transmission of COVID-19 and other illnesses daycares around the nation are implementing handwashing procedures for all students before entering the school. Currently, most commercial handwashing stations are too expensive and or not made for kids. For the Fall 2021 FirstYear Seminar (FYS) Service-Learning Project (SLP), students were tasked with designing a new portable and affordable, youth-sized handwashing station that could appeal to kids. Our team designed a dual electric pump solution to allow 50 students to wash their hands in 25 minutes. After being funded to create our solution, we built our first prototype and presented it for our class final. After making some final adjustments to that design, we will deliver it to a local daycare.

Prevalence of Domestic Violence During COVID-19 Lockdown
Jessica McDannel & Lily Domico mcdannel001@gannon.edu domico001@gannon.edu
Abstract
The map above demonstrates the amount of reported cases of domestic violence cases in 2018. Although a large portion of the central downtown area is highlighted in red, the reports of cases are more spread out throughout the city.
Previous research has shown an increase of domestic violence during natural disasters. With the recent COVID-19 pandemic, researchers noticed similarities between the pandemic and previous disasters. Although current research has been documenting the increasing prevalence of domestic violence, it is important to understand the impact it has had on our local community. This research examines the rates of domestic violence from 2018 to 2021 to compare the instances from pre- and post-lockdown. Using the Geographic Information System to interpret data provided by the Erie Police Department and the U.S. Census, the research examines the prevalence of domestic violence in Erie over the course of three years.
Conclusion
Although we do not see the hot spots shifting between 2019 and 2020, by looking at the density of dots, you can see the number of cases exponentially increases in 2020. As lockdown began in March of 2020, this map demonstrates in the increase of cases that can be attributed to said lockdown.
As stated prior, reports of domestic violence did increase throughout lockdown, however it is not shown on the map through using hot spots. By documenting the instances of reported domestic violence through dot densities, we were able to demonstrate the increase in said reports. With that, we saw that the number of instances were concentrated in the downtown area, especially during the height of the lockdown in 2020. Our findings are consistent with that of already documented increases of domestic violence throughout the United States.
We begin to see a general increase in reports during 2019. Although lockdown did not begin until 2020, the first case of COVID-19 is documented in December of 2019. We also begin to see a shift in the concentration of reports to the downtown area.
The line graph on the left depicts the increase of reported cases of domestic violence throughout the COVID-19 lockdown.
2021 still demonstrates a similar concentration of reported cases as seen in 2019 and 2020. However, as restrictions began to decrease throughout the year, you can see the density of cases begin to decrease as well.
Although it was steadily increasing from 2018 to 2019, it had peaked in 2020 and has since decreased. The most prominent type of domestic violence in 2018 was assault, as seen by our pin map above. This map is also consistent with our 2018 hotspot map, as crime is centralized in the downtown area.

The cure to CC has historically started with stopping HPV infections, a virus so prevalent it affects half of all sexually active adults. Gardasil® is an HPV vaccine available to both girls and boys, starting at the age of 13. Gardasil uses virus-like particles that resemble HIV virions to trigger the adaptive immune system of its host, yielding almost 100% efficacy. Additionally, CC screenings and pap smears are highly recommended to sexually active females over the age of 21. [1] If caught early, localized CC has a 91.9% survivability. [2] Once the cancer becomes metastasized, the percentage decreases to only 17.6%. The current treatment options for individuals with invasive CC includes radiation therapy, chemotherapy, and often, palliative care. Unfortunately, these treatments often come with severe side effects, such as infertility.

Gene Wild Type FAT1 (no mutations)
GAA AAA CCT TTG GAC Glu – Lys – Pro – Leu – Asp The cervix is the lower part of the uterus, connecting the uterus (womb) to the vagina (birth canal). Cervical cancer (CC) is the accumulation of cancerous cells centralized in the cervix. [1] CC makes up 0.8% of new cancer cases worldwide, with 2.2 out of 100,000 women dying of it per year. Nearly 95% of all CC cases are linked to the human papillomavirus (HPV), a common sexually transmitted disease. Untreated HPV infections can lead to the cervix’s squamous cells developing into carcinomas. Some cases of HPV affect the cervix’s gland cells and can become adenocarcinomas (cancer surrounding the gland cells).

The Cancer Genome Atlas (TCGA) is an open-access data portal that gives you an interactive guide to various mutations responsible for a particular cancer. Through TCGA, we identified frameshift mutations of the FAT1 gene that cause CC. We recognized these mutations in FAT1’s genetic code through Ensembl Archive, a portal where genes and their DNA sequence are public domain. We then took the newly mutated DNA sequence and translated it to a protein sequence through Expasy Translate. If the protein sequence did not present early stop codons, it was then compared to the FAT1’s wild type. The mutation chr4:g.186611683_186611684insT yielded a 35-mer neoantigen. This neoantigen was put through a BlastP search, ensuring that it was a novel protein and carried no similarities to proteins already found in humans. We used Moderna’s COVID-19 vaccine sequence as a template for this neoantigen. The sequence above displays a personalized mRNA vaccine for the frameshift mutation chr4:g.186611683_186611684insT of the FAT1 gene.

Cervical cancers (CCs) often involve human papillomavirus (HPV) infection, and infertility is a paramount concern in most surgical treatments. Various mutations in the tumor-suppressor gene FAT1 can result in CC, making it a gene of interest. By using open-access data portals, such as the Cancer Genome Atlas and Ensembl Archive, we identified a novel 35-mer amino acid sequence resulting from a frameshifted FAT1 mutation in cervical cancer patients. This neoantigen is foreign to the human condition, thus harboring potential to activate cytotoxic T leukocytes (CTLs) in an antitumor microenvironment. Using Moderna’s COVID-19 vaccine sequence as a template, we designed an mRNA cancer vaccine specific to our 1bp insertion allele of the FAT1 gene. Our cancer vaccine design is highly personalized, as it should train host CTLs to induce apoptosis in CC cells expressing only this 35-mer neoantigen. However, our vaccine would not work against other forms of CC.

Seeking Approval
This vaccine is highly personalized, being inoculated to individuals with this specific mutation on their FAT1 gene. In order for it to reach this step it must go through pre-clinical trials, ensuring that this neoantigen elicits an immune response and debilitates cancerous growth. The neoantigen will be ready for clinical trials once it passes the pre-clinical step and is approved by the appropriate administrations. Additionally, other cancers caused by frameshift mutations can be targeted using this method.

Mutated FAT1 (186611683_186611684insT)
GAA AAA TCC TTT GGA Glu – Lys – Ser – Phe – Gly [1] Mutations to the tumor-suppressor gene FAT1 are responsible for 9.64% of CCs. FAT1 is located on the antisense strand of chromosome 4. [2] FAT1 is the second most frameshift mutated gene that leads to cervical cancer, making FAT1 a gene of interest for an mRNA vaccine prototype. [3] mRNA vaccines code for mutant proteins that the immune system recognizes and neutralizes. Once inside the cell, the mRNA is transcribed in the cytoplasm and the mutated proteins are presented outside of the cell on its major histocompatibility complex class I (MHCI). MHCI display these novel peptides to additional immune cells, such as cytotoxic T leukocytes (CTL) and helper T leukocytes (HTL). CTL kill mutated cells while HTL create antibodies to deactivate these cells when the cancer presents itself in the host. Frameshift mutations are a type of mutation involving the insertion or deletion of a nucleotide in which the number of deleted base pairs is not divisible by three. [4] Our vaccine targets a FAT1 frameshift mutation between nucleotide 186611683 and 186611684 on chromosome 5. There, a thymine is inserted between nucleotides adenine and cytosine. This insertion shifts the remaining amino acid sequence until a stop codon is reached.

Most Frequently Mutated Genes Leading to Ovarian Cancer
What is Ovarian Cancer?
Ovarian cancers afflict the ovarian epithelium, fallopian tubes, and peritoneal tissues. The mean 5year relative survival rate for all ovarian cancers is 49.1%, however if caught early at the primary tumor site, survivorship is 92.6%. In metastasized cases, survival rate drops sharply to 30.3%. Surgery is the main treatment for all stages of ovarian cancers.

TP53
There are many known genes in which somatic mutations can yield ovarian cancers, of which TP53 alleles are the most frequent. TP53 plays an important role in the prevention of cancer formation. Typical roles include regulation of the cell cycle, apoptosis, genomic stability, and responses to stressors. TP53 aids in activating DNA repair proteins. It also has the ability to keep the cell cycle at the G1/S regulation checkpoint. If the DNA repair proteins and G1/S mechanisms fail, TP53 can preform apoptosis. These three regulatory mechanisms are why TP53 is important in the fight against cancer.

Since this type of cancer effects the ovaries only women are affected. The risk increases the longer a women has ovulated, therefore, those approaching menopause (women around the age of 50) are at the highest risk. The two bar graphs above, Percent of New Cases v. Age and Percent of Death vs. Age, demonstrate that women ages 55 to 65 have the highest development of ovarian cancer and ages 65 to 74 have the highest death rate of ovarian cancers. This data is consistent with the 5-year statistical death rate.

Title: RNA Cancer Vaccine Design Against TP53 Somatic Mutations in Ovarian Cancers Abstract: Ovarian cancers afflict the ovarian epithelium, fallopian tubes, and peritoneal tissues. The mean 5-year relative survival rate for all ovarian cancers is 49.1%, however if caught early at the primary tumor site, survivorship is 92.6%. In metastasized cases however, survival drops sharply to 30.3%. Surgery is the main treatment for all stages of ovarian cancers. There are many known genes in which somatic mutations can yield ovarian cancers, of which TP53 alleles are the most frequent. Here we computationally identified a frameshift allele of TP53 that when translated will generate a sequence of amino acids that we call a neoantigen unique to the human proteome. We then designed an mRNA vaccine for delivery to ovarian cancer patients harboring this precise TP53 frameshift allele. Injection of our vaccine design may help train host cell-mediated responses, particularly cytotoxic T lymphocytes to combat cancerous cells of a single TP53 frameshift lesion.

Frame shift mutations are mutations that delete or increase the nucleotide sequence by a number not divisible by three. If it is divisible by 3, the reading frame would not shift. The peptide sequence will be modified everywhere in the gene after the mutation until a stop codon is reached.

Bladder cancer is the sixth most common cancer in American patients. Out of all American bladder cancer cases, males account for 80% of patients and females account for just 20%. Bladder cancer is described in stages to distinguish its severity. Stage 1 bladder cancer begins in one type of tissue in the bladder and as it spreads to other tissues, organs, and lymph nodes it develops to stage 2, 3, and 4 cancer. As the cancer progresses, the 5- year relative survival rate decreases. More than 50% of bladder cancer is diagnosed at stage 1 because many of the symptoms are very evident. Current cancer treatments involve surgery, chemotherapy, radiation, immunotherapy, and targeted therapy.

An important step in finalizing the cancer mutation vaccine is to confirm that the vaccine will not attack similar proteins that are made normally by the body. Using NCBI’s BlastP, our results showed that a protein coded by the UTY gene, which is found only on the human Y chromosome, has similarity to the UTX mutant protein. The mutation causes the UTX gene to become UTY like. This UTX vaccine cannot be used in men because they contain the UTY gene on their Y chromosome which would also be a vaccine target. The vaccine will still be effective and safe in females because they do not normally have UTY protein.

Bladder cancer is often caused by genetic mutations. The most common gene involved in bladder cancer is UTX(KDM6A) found on the forward strand of the X chromosome. UTX can experience a frameshift mutation which we use as the subject of an mRNA vaccine. This mutation is a deletion of the cytosine that is the 44,974,679th nucleotide on the X chromosome.

First, we found cancer frameshift mutations that caused cancer and found which chromosome it was located on. Next, we searched the chromosome for the precise position of the mutation by examining the nucleotides. We used this map, along with the wildtype gene sequence to create the mutant sequence. Comparing the mutant translation to the wildtype translation we found our neoantigen. The neoantigen is the translated sequence which differs from the wildtype sequence. If proteins of the normal human condition were similar to the neoantigen, then trying to fight the neoantigen would cause an autoimmune response. To prevent this, we checked our neoantigen against proteins of the normal human condition. Lastly, we back translated the protein into the mRNA sequence and placed it into an mRNA vaccine design.

Methods
Bladder cancer is the sixth most common cancer in American patients. Mutations in the UTX gene are the third most common cause of bladder cancer. The UTX gene is located on the X-chromosome while UTY is found on the Ychromosome. Using public-domain cancer datasets, we identified a frameshift allele of UTX that generates a fragment of the UTY peptide sequence. Since all human females lack a Y-chromosome, this resulting UTY peptide sequence would be considered foreign to female immune systems, and thus can serve as a vaccine target to combat bladder cancer in females afflicted with a particular frameshift allele of UTX. Using Pfizer and Modern mRNA vaccines as templates, we designed a mRNA vaccine against our adopted UTX frameshift allele. Our approach is exceptionally personalized medicine, custom-tailored to the precise molecular basis of a single UTX frameshift allele.

Next steps include looking for a vaccine that can be used in men safely and effectively. Later, incorporating our vaccines into a lipid nanoparticle, which is used to introduce the vaccine into the human body, will be necessary for creating an mRNA vaccine. Once this is accomplished clinical trials can begin. This UTX Mutation Vaccine should only be used in females.

RNA Vaccine Design Against Novel Onco-Antigens in Breast Cancers Involving MAP3K1
Abstract:
Allele Mutation:
Breast cancer is the most common form of cancer in women in the USA. In 2021, the estimated number of new cases in breast cancers in the United States was about 280,000 persons, accounting for nearly 15% of all new cancer cases. Of all the cancers, breast cancer has seen great strides in treatment and positive prognoses, with a 5-year survival rate of over 90%. Survivorship is very much driven by cancerous stage, with greater survivorship seen in localized (confined to primary site) or regionalized (spread to regional lymph nodes) stages. Survivorship dramatically declines however in distant stages in which the cancer has metastasized, with 5-year survival rates at 29%. MAP3K1 is a serine/threonine kinase that makes up a key component of several different signaling pathways. Mutations in /MAP3K1/ are the fourth leading cause of all breast cancers. When mutations insert or delete nucleotides in non-multiples of three, a frameshift mutation can occur. Some frameshift mutations might result in the generation of a unique stretch of amino acids found nowhere else in the human proteome. Such a consequence of a frameshift mutation would thus generate a novel, non-self onco-antigen. We designed an RNA vaccine against one such MAP3K1 frameshift allele linked to breast cancer. Our RNA cancer vaccine design should in theory help train such an afflicted patient’s immune system, leveraging the cell-mediated response against any breast cancer cells presenting such neo-antigens via MHC class I molecules.

Nucleotide sequence:
Method: To develop an mRNA vaccine, we first sorted through frameshift allele mutations, focusing on mutations closer to the 5’ end of the chromosome. After mapping the frameshift sequence and adding the ‘CT’ nucleotides to encode the mutation, the sequence was translated. Comparing this new translation to the original amino acid sequence of the nonaffected allele, we could spot the oncoantigen, a 10-letter amino acid sequence, produced as a result of the mutation. Finally, the oncoantigen sequence was ran in blastP with the Homo sapiens filter as to find any similar sequences with significant alignments. This is done because we do not want the vaccine sequence to be similar to self-sequences. If sequences heavily overlap, introduction of the oncoantigen could cause the immune system to go into anaphylaxis. Lastly, the amino acid sequence was converted into an mRNA sequence. Start and stop codons, in addition to a 5’ cap and 3’-polyAtail were added to the sequence. This was then packaged into a lipid nanoparticle, and these contents constitute the cancer vaccine.

Title: RNA Vaccine Design Against Novel Onco-Antigens in Renal Cancers Involving VHL Abstract: Overall, renal cancers are the 8th most common type of cancer. In 2021, there were approximately 76,000 new cases of renal cancer in the United States, with approximately 13,000 deaths. The two most common genetic loci that underly half of all renal cancer diagnoses are the /VHL/ and /PBRM1/ genes. The /VHL/ gene encodes pVHL, a protein that binds to elongin C, elongin B, cullin-2, and Rbx1. This pentameric complex catalyzes the polyubiquitination of specific proteins to shunt them for destruction by cellular proteasomes. One target of pVHL is the HIF1a transcription factor. HIF1a drives cellular proliferation and angiogenesis via VEGF signaling. A functional pVHL diverts HIF1a to the proteasome, thus blocking excessive mitoses. We closely examined the precise nucleotide mutations and identified a frameshift allele that resulted in the generation of a novel stretch of polypeptide sequence found nowhere else in the known human proteome. Using EMBOSS Backtranseq and a human-optimized codon usage table, we reverse translated this onco-antigen and generated an RNA vaccine. Our RNA vaccine design is thus personalized to this specific allelic basis for renal cancer involving the /VHL/ genetic locus.

Role of SCAMP3 Regulating CXCR4 Trafficking Catalina Ordoñez Siza, Mikyung Jang, Dr. Quyen Aoh Department of Biology, Gannon University, Erie, PA 16501 Hypothesis
Abstract The CXC-Chemokine Receptor Type 4, CXCR4 is a G-protein coupled receptor that helps regulate cell growth and division, differentiation, and migration. Overexpression of CXCR4 is associated with metastasis in cancer and promotes HIV infection. CXCR4 can be overexpressed when its trafficking to the lysosome is decreased. When bound to its agonist CXCL12, CXCR4 is ubiquitylated and downregulated via endocytosis. At the early endosomes, CXCR4 is then sorted into multivesicular bodies destined for the lysosomes by the ubiquitin adaptor proteins Hrs and Tsg101. We are investigating the role of Secretory Carrier Membrane Protein (SCAMP) 3, which interacts with Hrs and Tsg101, in CXCR4 trafficking.

Control immunofluorescence assays were performed with pulse chase time of 5, 15, 30, and 60 minutes to examine CXCR4 localization. We have found that CXCR4 accumulates in Lamp1 and 2 positive compartments, indicative of lysosomes, at 60 minutes or later. We are currently working to optimize the assay to accurately measure colocalization with both endosomal and lysosomal markers.

Introduction
CXCR4 to lysosome
CXCR4 is downregulated through ubiquitylation and the ESCRT system CXCR4 is a G-protein coupled receptor (GPCR) that has been linked to metastatic growth in cancer cells. In the presence of its agonist, the chemokine CXCL12, CXCR4 activates signaling pathways involved in chemotaxis, cell adhesion, and cell growth [4]. Subsequently, CXCR4 is downregulated after interacting with its agonist [1,2]. Downregulation of CXCR4 is mediated by ubiquitylation, followed by endocytosis and endosomal sorting of the receptor into multivesicular bodies [2]. CXCR4 is ubiquitylated by the ubiquitin ligase ITCH, allowing it to be endocytosed into the cell. The receptors are then transported to early endosomes where they are sorted into multivesicular bodies (MVBs) by the endosomal sorting complexes required for transports (ESCRTs). Just prior to sorting, the receptors are deubiquitinated by the deubiquitinase, UBPY [5]. The MVBs then bud from the early endosome and fuse with the lysosome
SCAMPS are transmembrane proteins that regulate membrane traffic

HeLa cells are transfected with SCAMP3 –specific or control siRNA for two days to knockdown SCAMP3 expression
The cells will be stimulated with CXCL12 for up to 3 hours to induce endocytosis and lysosomal degradation of CXCR4
Determine localization of CXCR4 relative to endosomes and lysosomes
CXCR4 and markers for proteins found in early endosomes (EEA1) and lysosomes (LAMP1/2) will be labeled with different fluorophores for immunofluorescence microscopy. Colocalization between CXCR4 and the organelle will be indicated by overlap of the fluorescent signals.

HeLa cells were incubated with CXCL12 for 15 minutes, 30 minutes, and 60 minutes to induce endocytosis and lysosomal sorting of CXCR4. CXCR4 and the early endosomal marker EEA1 or the lysosomal marker Lamp1/2 were labeled through immunofluorescence. In an attempt to avoid cross-reactivity between the rat CXCR4 and mouse EEA1 and Lamp antibodies, fluorescence labeling was done sequentially. Colocalization is indicated by the presence of yellow. The cells were then mounted and observed using fluorescence microscopy.

In SCAMP3 knocked-down cells, endogenous CXCR4 will be labeled with a green fluorophore while the early endosomal marker EEA1 or the lysosomal markers Lamp1 and 2 will be labeled with a red fluorophore. Colocalization between the CXCR4 and organelle markers will result in overlap of the red and green signals to produce yellow.
SCAMPs are found in many places including the trans-Golgi network (TGN), endosomes, and plasma membrane. They function in the recycling and degradative process of cell surface receptors [3].

Experimental Design Knockdown SCAMP3 Stimulate endocytosis
The SCAMP family consists of five isoforms, SCAMPs 1-5. SCAMPs have four transmembrane domains with cytoplasmic N- and C-termini that facilitate interactions with other proteins. SCAMPs 1-3 are ubiquitously expressed and SCAMPs4 and 5 are neuronally expressed [3].
Results of Control Pulse-Chase Experiment
SCAMP3 may promote or inhibit CXCR4 trafficking to the lysosome
Effect of SCAMP3 Knockdown
SCAMP3 promotes the degradation of CXCR4
CXCR4 will be retained in the early endosome
SCAMP3 inhibits the degradation of CXCR4
More CXCR4 will be trafficked to the lysosome
Localization relative to early endosomes
Localization relative to lysosomes
At 15 min, EEA1 appears colocalized with CXCR4 (see yellow merge image). However, does not have the same punctate distribution in the duplicate time samples stained with Lamp antibodies. This suggests our secondary antibody used to fluorescently label CXCR4 may be inadvertently labeling EEA1 as well.
Conclusions and Next Steps Sequential staining of CXCR4 and organelle markers improved specificity of signal in the immunofluorescence. Also, using LAMP1 and LAMP2 together increased the colocalization of CXCR4 with the lysosomes and our preliminary results show that CXCR4 is correctly trafficked to the lysosomes after two hours of stimulation. However, the secondary anti-rat antibody used to fluorescently label CXCR4 may be inadvertently also be labeling the anti-mouse EEA1. Our next step will be to optimize the labeling and blocking conditions and to use F(ab2) linked fluorophores to reduce cross-reactivity between our rat and mouse antibodies. In future studies we will perform a knockdown of SCAMP3 using RNAi interference and perform the pulse chase and indirect immunofluorescence assay to examine CXCR4 localization.
Title: Role of SCAMP3 Regulating CXCR4 Trafficking Abstract: The CXC-Chemokine Receptor Type 4, CXCR4 is a G-protein coupled receptor that helps regulate cell growth and division, differentiation, and migration. Overexpression of CXCR4 is associated with metastasis in cancer and promotes HIV infection. CXCR4 can be overexpressed when its trafficking to the lysosome is decreased. When bound to its agonist CXCL12, CXCR4 is ubiquitylated and downregulated via endocytosis. At the early endosomes, CXCR4 is then sorted into multivesicular bodies destined for the lysosomes by the ubiquitin adaptor proteins Hrs and Tsg101. We are investigating the role of Secretory Carrier Membrane Protein (SCAMP) 3, which interacts with Hrs and Tsg101, in CXCR4 trafficking. RNA interference will be used to knockdown SCAMP3 and CXCR4’s localization relative to markers of the early endosome and lysosomes will be monitored through indirect immunofluorescence. Control immunofluorescence assays were performed with pulse-chase time of 15, 30, 60, and 120 minutes to examine CXCR4 localization. We have found that CXCR4 accumulates in Lamp1 and 2 positive compartments, indicative of lysosomes, at 60 minutes or later. We are currently working to optimize the assay to accurately measure colocalization with both endosomal and lysosomal markers.

Role of Tanycytes in Individual and Social Behavior Abstract and Introduction to Tanycytes
Social Behavior: Autism Spectrum Disorder and Schizophrenia
Tanycytes are a type of glial cells located around the third ventricle among the hypothalamic neurons. These cells affect hypothalamic functions, such as energy homeostasis, appetite control, and thermoregulation. It has been demonstrated that any dysfunction of tanycytes can have an impact on social cognitive behavior. Tanycytes have been hypothesized to play a role in the development and onset of social cognitive behaviors. Among these are schizophrenia (SCZ) and autism spectrum disorder (ASD), two major disorders that have been studied in relation to tanycyte morphology and physiology. Knowledge about the basic molecular and behavioral pathology of SCZ and ASD allows further investigation to establish the link between tanycytes and social cognitive behavior. As the tanycytes are mainly located in the hypothalamic parenchyma affecting hypothalamic metabolic function, this review calls into question the association between tanycytes in the hypothalamus and neurodevelopmental disorders that could potentially reveal etiology of major neuropsychiatric disorders.
Tanycytes are also involved in various social behaviors and disorders like autism spectrum disorder and schizophrenia. These disorders are both classified as neurodevelopmental in nature due to their hallmark social cognitive deficits.
Tanycytes are specific ependymal cells that communicate with the hypothalamus via long projections. Tanycytes, along with astrocytes and other glial cells, are used to convey metabolic activity throughout the brain. These cells are necessary for maintaining projects of the hypothalamus, such as regulating energy, appetite, and body temperature. In addition, tanycytes are also hypothesized to induce hyperactivation of the thalamic regions and are responsible for neuroinflammation in fetuses when dysfunctional within the mother. Each of these functions of tanycytes has an impact on both individual metabolic behavior and social cognitive behavior. We aim to discuss these relationships.
Individual Behavior: Metabolism and Diet
Department of Biology, Morosky College of Health Professions and Sciences Discussion Tanycytes are influential in regulating the HPT axis. They are responsible for controlling the crossing of blood-borne substances in the periphery of the brain and then functioning as chemosensors to send signals into the parenchyma. While initial studies have been conducted, it is still not fully understood how tanycytes regulate the HPT axis in vivo (Figure 4).
Autism Spectrum Disorder Autism spectrum disorder (ASD) is often seen in early childhood, and the disorder is accompanied by aboveaverage brain volume and rapid development. Abnormal cell morphologies of tanycytes and other neurons within the hypothalamus are likely a contributing factor to the development of ASD; tanycyte activity results in altered connectivity between social and emotional response mechanisms. It has been hypothesized that due to the large role of tanycytes in metabolism regulation, these cells could contribute to a high brain volume surrounding the third ventricle, another hallmark of ASD (Figure 2).
More research is necessary in terms of where and how tanycytes sense glucose within the brain. Tanycytes contain all the necessary components for glucose sensing, which is typically done by the pancreatic beta cell paradigm. To test if tanycytes are also involved in this function, Ca2+ imaging was done to find if tanycytes could sense glucose when applied directly to the cell body. The study found that this caused a surge of Ca2+ waves and released ATP. This suggests that tanycytes have a role as biosensors, but whether they respond to the glucose concentration in the CSF or parenchyma is still unknown.
Schizophrenia Schizophrenia (SCZ) appears in late adolescence and is marked by psychosis, paranoid delusions, and auditory hallucinations. Because SCZ tends to develop when the prefrontal cortex is still developing, damage can occur in this brain region. This disruption in normal morphology is a result of low activity of the N-methyl Daspartate (NMDA) receptor on gamma-aminobutyric acid (GABA) inhibitory interneurons, which are prevalent in this brain area. SCZ has been classified by social cognitive deficits, which are associated with abnormalities within the hypothalamic parenchyma. Because this brain region is highly regulated by tanycytes, tanycytes may play a role in the development and onset of schizophrenia.
Tanycytes may influence ASD, but it is also possible that ASD can influence tanycytes as well. Patients with ASD have been shown to have impaired cellular metal homeostasis, which results in hyperactivation in the cerebellum. This can polarize microglia like tanycytes, leading to neuroinflammation and dysfunction. More research is also needed on the involvement of tanycytes in SCZ. Tanycytes are known to be related to SCZ via that hypothalamic parenchyma, but just how has yet to be determined (Figure 5).
Anatomy and Physiology of Social Behavior Social deficits found in ASD have been linked to oxytocinergic system disfunction. Because oxytocin production occurs in the third ventricle of the hypothalamus, tanycyte activity may be involved in this oxytocinergic regulation and social deficit development (Figure 2). Synaptic pruning is also hypothesized to play a role in the development of neuropsychiatric disorders. Microglia, including tanycytes, may contribute to synaptic pruning and modulation in both normal and abnormal conditions. Discrete glial signaling pathways send peripheral signals to the hypothalamus during synaptic pruning; tanycytes could potentially be involved in this process (Figure 3).

Figure 1. Tanycytes, along with cells of the arcuate nucleus of the hypothalamus, secrete lactate, which acts on specific receptors to regulate energy homeostasis. Tanycytes are involved in human metabolism and diet. In the case of metabolism, tanycytes sense glucose levels by expressing the GLUT1 and GLUT2 glucose transporter genes. These transporters measure glucose levels from the cerebrospinal fluid (CSF), and the tanycytes can then take that information and provide an appropriate response. This response is due to the tanycytes’ connection to hormone levels and tight junctions, and the response is different depending on the presence (or lack) of glucose. A deficiency of nutrients like glucose can cause the production of blood-borne molecules, which alert appetite neurons. As a result, our metabolism is maintained and regulated through the action of tanycytes (Figure 1).

Secretory Carrier Membrane Protein 3’s (SCAMP3) Role in β-Amyloid Production and Secretion Alexandria Zarilla, Daniel Oar, Joshua Nel, Dr. Quyen Aoh Department of Biology, Gannon University, Erie, PA 16501 Preliminary Results
Abstract Alzheimer’s disease is a neurodegenerative disease associated with loss of memory and cognitive function. The aggregation of extracellular plaques containing b-amyloid is related to the processing of the amyloid precursor protein (APP). When endocytosed to the early endosome, APP will either be degraded by the lysosome or sent back to the trans-Golgi network. Degradation of APP is regulated by endosomal sorting complexes required for transport (ESCRTs). Disruption of ESCRT function leads to accumulation of b-amyloid. The secretory carrier membrane protein 3 (SCAMP3) interacts and opposes the function of the ESCRT proteins. In this study, we have found that expression of APP-EGFP in H4 neuroglioma colocalizes with SCAMP3. Interestingly, APP-EGFP and SCAMP3 are found in the trans-Golgi Network in transiently transfected cells and in the late endosome/lysosome in stably transfected cells. These results suggest that SCAMP3 has a role in regulating APP trafficking in the TGN-endolysosomal system. We hypothesize then that SCAMP3 may regulate APP trafficking by promoting or inhibiting trafficking of APP to the lysosome and propose to examine SCAMP’s effects using RNA interference in both an immunofluorescence and biochemical ELISA assays.
Introduction Production of b-amyloid is regulated by membrane trafficking Alzheimer's disease (AD) is a progressive neurodegenerative disorder that slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks. More than 5 million Americans have AD. It thought to be caused by the aggregation of extracellular plaques containing β-amyloid which is related to the processing of the amyloid precursor protein (APP) [3]. The degradation of APP is regulated by the endosomal sorting complexes required for transport (ESCRTs). Disruption of ESCRT function leads to transport of APP to the TGN where it is cleaved to b-amyloid, resulting in accumulation of β-amyloid [3]. Previous studies have shown that secretory carrier membrane protein 3 (SCAMP3) interacts with ESCRTs that function in APP processing [1].
SCAMPS are transmembrane proteins that regulate trafficking The SCAMP family consists of five isoforms , SCAMPs 1-5. SCAMPs have four transmembrane domains with cytoplasmic Nand C-termini that facilitate interactions with other proteins, such clathrin adaptors and ubiquitin ligases.
Experimental Design
Transiently Expressed APPGFP is found in lysosomes and SCAMP3-positive organelles H4 cells were transiently transfected with APP-GFP and then subjected to indirect immunofluoresence using antibodies to SCAMP3, EEA1, or LAMP1 and 2 (red). Images were captured and then superimposed to show colocalization. APPGFP is found colocalized with SCAMP3 and lysosomes. These results suggests Golgi and endolysosomal compartments are not altered early in b-amyloid expression. Furthermore, APP-GFP is traverses SCAMP3-positive compartments, that are likely Golgi in nature and may contain the bsecretase (BACE1) that cleaves APP to its amyloidgenic form.

Stably transfected APP-GFP is found in lysosomes and alters SCAMP3 distribution H4 cells were stably transfected with APPGFP and then subjected to indirect immunofluoresence, and microscopy as described above. APP-GFP is colocalized with enlarged lysosomes but not with SCAMP3 in the trans-Golgi Network. Moreover, the distribution of SCAMP3 and EEA1 appears more diffuse. These results suggest that lysosomes are enlarged and that trafficking of SCAMP3 between endosomes, lysosomes, and the TGN is altered upon extended b-amyloid expression. Our study will next focus on determining if SCAMP3 affects the APP trafficking and processing .

We hypothesize SCAMP3 regulates trafficking of APP at the early endosome by either (A) promoting trafficking of APP to the lysosome, thus increasing β-amyloid production or (B) inhibiting trafficking of APP to the lysosome, thus decreasing β-amyloid production. Therefore, the knockdown of SCAMP3 should result in colocalization of APP with either the lysosomes or the early endosomes and a concomitant increase or decrease in β-amyloid levels.

Duplicate samples will be stained with antibodies to the early endosomal marker, EEA1, or the lysosomal markers, LAMP1 and Lamp2, and labeled with a red fluorophore. Colocalization between APP-GFP and organelle markers will result in overlap of the red and green signals to produce yellow. If there is no colocalization, the red and green will appear separately.

SCAMPs are found in many places including the TGN, endosomes, and plasma membranes [1]. They function in the recycling and lysosomal targeting of cell surface receptors [1,2]. SCAMP3 specifically has been shown to regulate degradation of the epidermal growth factor receptor by interacting with and opposing the function of the ESCRT proteins Hrs and Tsg101 [1]. SCAMP3 is ubiquitously expressed in many cell types including neurons, and therefore likely plays a role in regulating the trafficking of many other proteins [1,2].

Title: Secretory Carrier Membrane Protein 3’s (SCAMP3) Role in beta-amyloid Production and Secretion Abstract: Alzheimer’s disease is caused by the aggregation of extracellular plaques containing b-amyloid and the processing of the amyloid precursor protein (APP). APP trafficking is regulated by endosomal sorting complexes required for transport (ESCRTs). When endocytosed to the early endosome, APP will be degraded by the lysosome or cleaved into b-amyloid by the trans-Golgi Network. The secretory carrier membrane protein 3 (SCAMP3) may help regulate APP trafficking through interactions with ESCRTs. We found that APP-EGFP expression in H4 neuroglioma cells colocalizes with SCAMP3. Interestingly, APP-EGFP and SCAMP3 are found in the trans-Golgi Network in transiently transfected cells and the late endosome/lysosome in stably transfected cells. This suggests that SCAMP3 has a role in APP trafficking in the TGN-endolysosomal system. We hypothesize that SCAMP3 may regulate APP trafficking by promoting or inhibiting trafficking of APP to the lysosome. We will examine SCAMP’s effects using RNA interference in an immunofluorescence and ELISA assay.

Should There Be Education About Cannabis in Medical Schools?
Regan Tetrick tetrick001@gannon.edu
Education Regarding Cannabis in Medical Schools Will Benefit Patient Care
Overview Medical Cannabis is becoming a more commonly discussed as well as controversial issue in the United States, yet there is very few educational opportunities for healthcare workers or medical students to learn about this substance in their required curriculum. Medical schools that currently do not educate their students about cannabis should add this to the required curriculum for healthcare professionals.
Lack of Education on Cannabis in Medical Schools • “Physicians and Healthcare workers do not feel prepared to encounter situations where knowledge about medical cannabis or recreational cannabis is necessary. • There are many questions following the use of cannabis and whether the utilization of this substance is safe, effective, addictive, or necessary compared to the other medications that are available in the medical field today. Regardless of the view on whether marijuana should be legalized medically or for recreational use. • Only 9% of medical schools across the U.S. educate their students (future healthcare professionals) about cannabis. • According to Harvard Health, marijuana is currently legal, on the state level, in 29 states and about 85% of Americans support legalizing medical marijuana. However, the lack of education on the subject in medical schools is alarming, despite the increasing rates of use (Grinspoon, 2020).
• The lack of education regarding this substance can have negative impacts on patient care because if a patient is participating in the medical or recreational use of cannabis, and is seeking medical attention, a healthcare professional may not be knowledgeable enough to provide sufficient care. However, if a physician or healthcare professional is educated about cannabis, regardless of whether or not they approve of the use, they will be better equipped to handle the situation. This will allow them to be confident in their medical course of action and provide the patient with better quality medical treatment (Boehnke, 2021). • A study was conducted in the year 2020 asking healthcare professionals about their education regarding cannabis. More than half of the study participants never received any education on medical cannabis (60.1%); 71.1% declared their knowledge was insufficient to counsel patients about medical cannabis use (Manuel, 2021). • Another study regarding the education of medical marijuana was done, asking residents and fellows if they felt prepared to prescribe this medication in places where it was legal. An overwhelming 89.5% of these residents and fellows reported that they did not at all feel comfortable prescribing this medication and 35.3% added that they did not feel comfortable or educated enough on the subject to even answer questions related to cannabis (Evanhoff, 2017).
.
Understanding the Use of Medical Cannabis Will Allow More Treatment Options • The use of medical marijuana is legal in over half of the United States, yet most of the country’s current healthcare professionals have not been educated about the subject and future healthcare workers are not currently being educated about cannabis. Because current physicians do not feel at all prepared to prescribe this medication, this narrows the treatment options for all patients, even if this medication could potentially be beneficial in their treatment plan.
Conclusion • Regardless of the personal opinions or state legalization policies, education about cannabis should be introduced into the medical curriculum required for healthcare professionals. Medical cannabis is most commonly used for treating pain in patients and is used compared to other pain killers like opioids because it has been proven to be less addictive among patients. This is a substance that is becoming more commonly used across the United States and therefore, should be a part of the education of healthcare professionals. References

Steps to Changing Eyewitness Testimony
Harley Johnson johnson232@gannon.edu
Overview
Courts Reducing Risks of Wrongful Convictions
Eyewitness testimony needs to be changed, not only is it proven to be unreliable, but it leads to wrongful convictions because of issues associated with it that the justice system has attempted to fix.
• The Innocence Project has statistics on their exonerations, eyewitness testimony played a role in a surprising 75% of the convictions that have been overturned as a result of DNA evidence. o 50% of those cases, eyewitness testimony was the central cause of conviction. (Vallas, 2011). • The two-step inquiry is a test used by the courts to determine whether due process will conclude “whether the identification procedure was unnecessarily suggestive” making it unreliable, preventing it from being used. (Gates, 2013). • 14 states adopted policies drawn up by the Innocence Project o The policies included limiting exposure of the witness to a suspect before formal identification takes place; blinding the person administering the line-up to who the real suspect is (double-blind testing); telling the witness that the perpetrator may or may not be in the line-up, so they don’t feel pressured to choose someone; and recording their confidence in the identification, should they make one. (Geddes, 2016).
Eyewitness Unreliability • Variables that affect eyewitness memory (Rodriguez, 2016). o System variables are factors over which the legal system has control ▪ Ex: lineups or interviews o Estimator variables are those that the legal system cannot control ▪ Ex: scene stress factors or memory decay
• Some of the other factors that contribute to the unreliability (Vallas, 2011). o Own-race bias where the eyewitness has more difficulty remembering people of their races’ features o Violence, stress, and a weapon focus could have detrimental effects on the ability of the eyewitness to identify accurately o Exposure duration and retention interval as the memory will deteriorate over time o Post-event Information such as suggestive instructions to the eyewitness that may change the memory of the event. o Witness confidence will affect how the trial will go even when the confidence is misplaced o Type of crime committed and how violent the crime was
• Some more changes the system has adopted are including only one suspect per lineup and making the suspect not stand out in the lineup by having fillers with similar features. (Wixed, 2017). Pick Out the Penny Example • The Innocence Project uses this example to show off just how malleable your memory of a very common thing is o Showing just how much human error is involved in eyewitness testimony • It shows off some of the variables that are assigned to eyewitness testimony o Memory issues o Legal interviewing issues • If you chose a penny, then you have fallen victim to the system o None of the pennies in the picture are a penny o Saying “pick out the penny” led you to believe that there was one, changing your memory of how a penny looks
State Policies → Solutions • The I-I-Eye (interview-identification-eyewitness) system analyzes eyewitness accuracy in three steps; first being evaluating interviews conducted by law enforcement, second evaluating the identification procedures, and third asses how the factors of the crime scene affected the eyewitness accuracy. (Pawlenko, 2013). • The tripartite solution permits expert testimony when primary or sole evidence against the defendant is eyewitness testimony and improves law enforcement’s procedures for collecting eyewitness evidence. (Wise, 2007). • Educating judges and jurors about eyewitness testimony unreliability and making sure that they understand that it isn’t the only evidence, human error is involved with eyewitness testimony References Carpenter, A. C., & Krendl, A. C. (2018). Are eyewitness accounts biased? Evaluating false memories for crimes involving in-group or out-group conflict.

Title: Steps to Changing Eyewitness Testimony Abstract: Eyewitness testimony has helped make many arrests in all different kinds of crimes, but it is not always reliable. Should it be used as a piece of evidence if it cannot be proven by physical evidence since human error is involved? Vallas (2011) noted that “According to the Innocence project, eyewitness testimony played a role in a surprising 75% of the convictions that have been overturned as a result of DNA evidence.” Many experts have done studies showing that a majority of judges and jurors do not have enough knowledge to correctly analyze eyewitness testimony. Unless something is done to obtain more knowledge about eyewitness testimony the justice system will continue to be unfair.

Background
Materials and Methods
Expected Outcome
Future Work
About 13% of flight attendants are injured each year, which doesn’t seem large but comes to about 13,500 per year. Out of those injuries, 58% were musculoskeletal involving the neck, back, and shoulders, with the most injuries being for stewardesses in the range of 4-6 years of experience.[1].
Unity 3D was utilized to create a virtual environment in which the subject would complete four tasks which were the highest percent of injury, excluding natural phenomenon. They include putting luggage in the overhead bin, pushing the service trolley, closing the airstair door, and reaching across the seats to serve the passengers.
Further work needs to be done before the project is completed. The final two tasks need to be created in Unity, and the data collection and analysis still need to be done. After stewardesses are trained using the Unity 3D, Oculus Rift, and Xsens, it is expected that the rate of injury will decrease. When comparing to other industries, a statistically significant difference was found before and after the use of this injury prevention method [3].
Injury prevention work using VR has been done in multiple settings, but most include the private sector and not the public one. Jobs like firefighters haven’t had a lot of work done in terms of injury prevention using VR. Considering they are high in terms of injuries, they could benefit greatly from this work [4]. Any industry with high injury rates could benefit from injury prevention from the use of VR.
Figure 2: Example of task one, putting the luggage in the overhead bin
The subject is put into the VR environment through the use of an Oculus Rift, which not only lets the subject view but also interact with the game objects through the use of the controllers. To track the motion while the subject does the actions, an Xsens suit with trackers will be worn. The motion data will then be recorded with Xsens and further analyzed. Posture will be evaluated for injury prevention to see if the subject is at risk based on joint angles. Since most of the injuries Figure 3: A subject utilizing the Oculus Rift occur in the neck, setup back, and shoulders, that data will take priority when being analyzed.
Figure 1: Frequency of factors associated with stewardess back injuries [1]
Training simulations have been used in other areas, such as medicine, sports, and warehouses. They can be used to practice medical procedures, injury prevention in a variety of sports like football and baseball, and injury prevention in warehouse situations like lifting heavy objects and assembly line work. The application can reasonably be applied to stewardesses for the same effect [2].
Aim: To decrease the frequency of musculoskele-
tal disorders by evaluating the posture and form of a subject completing tasks inside a virtual environment. In order to complete this, the environment was designed in Unity 3D. The subject is to complete the four tasks that consist of the main causes of injuries, which include storage in the overhead bins, operating the service trolley, closing the airstair door, and reaching across seats to serve the passengers.

It is reasonable to assume that since injury prevention worked and lowered the risk of injury in an industrial setting, it will also work for stewardesses. To determine if it will be effective at the same rate as other industries, the effectiveness of injury detection will be evaluated since it is still in the research setting at the moment. The procedure should be valid since the Xsens trackers have been validated in reference to their accuracy of tracking. Hence, the results should be accurate.

An Oculus Rift S then put them inside the environment, and Xsens sensors recorded motion data. The data can then be analyzed to see if the trainee is at risk of injury based on the form used during each task.

Stimulating Garden Activities for the Residents of PASSH with Alzheimer’s Disease and Dementia Lindsay Steis1, Brady Johnson1, Hunter Telford2, Jacqueline Sandquist2, Tyler Seelnacht3, Andrew Snowdy3, Kaitlin Sidare4, Scott Fennell5 Environmental Engineering1, Mechanical Engineering2, Electrical Engineering3, Biomedical Engineering4, Computer Science5
Abstract
The Pennsylvania Soldiers’ and Sailors’ Home (PASSH) is a nursing home located in Erie, PA, that is dedicated to providing care and assistance to veterans. The goal of the project is to engineer and implement two raised, wheelchair accessible garden beds with a self-sustaining water distribution system in the courtyard area for the residents with Alzheimer’s disease and Dementia. With thorough consideration, the dimensions, construction, and function of the raised garden beds at PASSH have been designed to be accommodating and assure that the raised garden beds will be wheelchair accessible, structurally safe, and fitting for the space (Figure 1). It was calculated that a horizontal, forty-gallon storage container would be sufficient in holding enough water to supply both garden beds with an adequate amount of water throughout the seasons. Irrigation tubing will be used to channel the water to the garden beds.
Both garden beds are 7 x 4 ft. and will be placed in the courtyard area of PASSH (Figure 4). One bed will have flowers and the other will have herbs. The beds have a 2 x 4 x 7 ft board running down the middle to add extra structural support to the bed (Figure 2b). Each bed will have six legs and trusses running about halfway down the length of the legs to help distribute the weight of the moistened soil more efficiently. As shown in Figure 2a, the legs of the beds will run the whole height of the bed to lessen the weight of the soil needed and to more efficiently piece together the sides of the bed. The beds will each have about 8 in. of soil which still allows for many plants to grow properly. In addition, the beds will each have an inside liner to protect the wood from any weathering or wear. However, the liner will still have drainage holes to allow water to drain when needed.
About PASSH
PASSH serves as an important historic marker throughout Erie County since opening in 1886. Residents at PASSH enjoy an active lifestyle where they participate in organized programs such as holiday parties, billiard tournaments, and BINGO. The residents are really looking forward to spending more time outside and interacting with the improved space. Acknowledgements

Figure 3b: Top view of courtyard including garden beds and water distribution system
Water Collection and Distribution System The water tank will be raised for the system to be gravity fed (Figure 3a). The system will collect water from the surrounding rooftops and will use sensors planted within the beds to measure and automatically adjust the moisture of the soil. An Arduino and a small solar panel will assist with the automation. There will be a sub-system called a first flush diverter that will divert the first few minutes of rainfall since this typically has the highest levels of contaminants. Additionally, the irrigation tubing will run underneath the soil serving as another precautionary measure to limit contamination to the herbs that the residents will consume. There will also be drainage ports to assure that any overflow of the water tank will be drained into the sewer (Figure 5). The irrigation tubing is to be less than ½” to prevent a passage hazard for the residents and to allow the tubing to fit in the cracks of the pavement. If necessary, wire coverings will be used to prevent ramps from having to be installed to avoid residents having to navigate over the tubing (Figure 3b).
Figure 5: Drain and sewer area for elevated water tank
This area will be where the water distribution system and the elevated water tank will be placed. Water from the surrounding rooftop areas will drain into the water tank and will be stored until the solenoids signal the system to release water into the garden bed(s) that have low moisture. Any overflow will be filtered to drain in the sewer drain shown in Figure 5.

The Assessment of Robotic Platform in the Application of Aviation Ruba Alshaeri, Davide Piovesan, Xiaoxu Ji
Biomedical Engineering Program ,Gannon University, Erie, PA, 16541
Background:
Methods:
References:
Simulations have been used for decades to get further insights on their real-world working mechanisms to gain an understanding on how different systems work. Robotic platform has been word widely designed and developed for industries and academia to execute the control concepts in different sectors. Simulation has been used to mimic the dynamic properties of LHD vehicles and skidders in the underground mining and forestry environment (Ji et al., 2016; Ji et al., 2015); It, also, has been applied in the boat section to obtain the best orientation via utilizing the optimization algorithm (Blanco, J. C., & Rodri´ guez, 2010), and applied in the intrafraction respiratory system to enhance the evaluation of respiration-correlated radiation therapy procedures (Fitzpatrick et al., 2005).
In this study, the specific force will be applied to the horizontal moving direction of the platform shown in Figure 1. The frequency range will be selected from 0.1 rad/s to 16 rad/s with the force input amplitude of 1m/s2, based on the requirement provided by FAA (2016) shown in Table 1. A total testing time of 200-300 seconds will be generated for each of the trials. A piezoelectric sensor (model 3-01-1504, HiLetgo) will be mounted on the center surface of the platform to collect the accelerations in x- and y- directions, in order to evaluate the accuracy of movement in the horizontal direction.

Currently, the robotic platform technology is prevalently used in the commercial airlines and military for the purpose of aircraft development and pilot training, to ensure that the flight crew familiarize the normal and emergency operating procedures (Plitea et al., 2006). Consequently, it is important to simulate different weather conditions and see its effect on the flight and how the pilot react to these harsh environmental conditions such as rain, wind, and snow (White et al., 2021). Multiple variables must be included during simulation, such as the frequency and amplitude (Federal Aviation Administration (FAA), 2016). Considering that the flight simulator has led to rapid developments of higher speeds, enhanced maneuverability, and improved efficiency. Significance: The purpose of this study is to create an optimum simulation for the robotic platform to achieve the real experience in aircraft. It would make a major contribution to the aviation training and safety.

Title: The Assessment of Robotic Platform in the Application of Aviation Abstract: Flight simulations has been used worldwide to mimic the real-world situations which would help pilots to train for emergency situations that may not be able to safely execute in a real world. Through the use of objective motion tests, our research will also provide direction to sponsors of flight simulation training devices and training device makers. Several factors, such as frequency and amplitude, must be included in the flight simulation to simulate different harsh environmental conditions. For this study, the frequency range will be set between 0.1 and 16 rad/s, with a force input amplitude of 1m/s2, in accordance with FAA requirements (2016). For each trial, a total testing duration of 200-300 seconds will be generated. Future study might make use of this platform and software to test different automobiles and conduct vibration and ergonomics analyses on how people interact with them.

Abstract: The goal of this experiment is to determine how the addition of ethanol affects heart rate in crustacean daphnia magna species as compared to a control group. This experiment was conducted as a TC50 study exposing these organisms to ethanol in increasing amounts. Methodology based on the procedure outlined by Carolina Biological Supply Co. (see References) was used to collect daphnia magna heart beats per minute values. It was found that the average heart rate for the daphnia magna culture used was 226.43 bpm. The main result is that the TC50 value for ethanol is 115 % (v/v). In conclusion, ethanol behaved with a threshold as it impacted the daphnia magna culture most in higher concentrations. Background: Ethanol, an organic compound known as C2H5OH, is a common compound frequently used in gasoline and alcohol, creating means of exposure to both humans and the environment. Ethanol is known to affect the central nervous system by depressing inhibitory activity of the brain, suggesting a decrease in heart rate will occur when exposed to ethanol (Britannica, T. Editors of Encyclopaedia, n.d.). A previous study depicts that steady immersion decreased the heart rate of daphnia to 176 ± 10 bpm; also observed was marked irregularities in heart rhythms post ethanol exposure (Corotto, F., Ceballos, D., Lee, A., & Vinson, L., 2010). The concentrations used in this experiment begin with a minimum value of 0.00025g/L of ethanol because EPA guidelines list water standards in parts per billion (ppb) since daphnia show sensitivity to different chemicals in such low concentrations (Mercer Island Schools, n.d.). Daphnia magna were chosen due to their relatively larger size (compared to other types of daphnia) that allows their heart to be easily visible and also for their susceptibility to drugs that are known to affect the human heart (Kaas, B., Krishnarao, K., Marion, E., Stuckey, L., & Kohn, R., 2009).
Methods: ● Focusing on one trial at a time, five solutions of ethanol concentrations (see Table 1) were mixed. A control solution of 100 mL of spring water was used. ● Heartbeat values were obtained for 100 daphnia magna (50 organisms per trial, with 10 organisms in each of the five concentration groups). ● The procedure outlined by Carolina Biological Supply Co. (see References) for monitoring daphnia heart rate was used. ● Using the Boreal Light Microscope Model No. 57900-15 microscope, the heart beats were counted for a 15 second time frame. This value was multiplied by four to obtain a beats per minute value. Heartbeat values were taken pretreatment and posttreatment. ● Each dosing group was tested sequentially in increasing concentration amounts to prevent contamination for the lower concentrations. Trials were completely separate.
Results: This experiment used paired T-tests to see if the difference in heart rate before and after treatment (adding ethanol) was statistically significant. This was done for control and each dose (See Table 2).
The heart rates (bpm) of the daphnia magna pretreatment and after posttreatment were not significantly different for the control group, or for the first three dosing groups. It is expected to see no significant change in the control group. As dose increases, the change gets closer to being significant, but without meeting the usual statistics guidelines. Therefore, small amounts of ethanol did not have a significant change to heart rate and only at the highest concentration was the change in heart rate significant. A two-sample T-test was used (assuming equal variance) to see if the heart rate reduction in dosing groups varied significantly from that of the control. Heart rate reduction of Control was compared to that of Concentration 1, Control to Concentration 2, and so on (See Table 3).
Figure 1 shows the spread of heart rate change by concentration.
Heart rate values changed about as much in the first three dosing groups as they did in the control. Heart rate reduction for concentrations 1-3 was not significantly different from the control. Concentration 4 did have a significant difference in heart rate reduction from the control group.
Figure 2 plots the log(concentration of ethanol) vs. mean change in heart rate in probits. The Y-value of 5 probits corresponds to 50% reduction in daphnia heart rate. The corresponding concentration represent the TC50 value.
Conclusions: Our main conclusions are: ● The TC50 value for ethanol is 115 % (v/v). ● Change in heart rate from treatment vs. no treatment is not as evident until high concentration doses.

Making the Most of the Daphnia Heart
Variation between control and dosing groups is expected to increase as concentration increases. Concentration 3 heart rate changes are further from those of the control than those of concentration 1, but the difference is not significant until reaching Concentration 4. Overall, ethanol appears to have little effect on heart rate at low concentrations. The relationship between ethanol and daphnia magna heart rate presents less like a ‘dose-response’ relationship and more like an ‘effect after reaching a threshold value’ relationship.

Title: The Effects of Ethanol on the Heartbeat of Daphnia Magna Species Abstract: How does the addition of ethanol affect heart rate in the freshwater crustacean species, Daphnia magna? Research regarding ethanol is pertinent because of its widespread usage and thus its frequent exposure to humans and to the environment. Ethanol, a simple alcohol with the formula, C2H5OH, acts as a solvent, is an additive to gasoline, and is the inebriating component of many alcoholic beverages. Known health effects regarding ethanol are its toxic effects on the central nervous system, as it causes muscle relaxation and depresses inhibitory activities in the brain. Larger quantities of ethanol can interfere with coordination and judgment and can lead to coma or death. Prior research regarding this substance suggests that a decrease in heart rate will occur to exposed Daphnia, and this poster presents the findings of this experiment as individual organisms are exposed to increasing concentrations of ethanol.

The compression testing machines that will be used in this experiment can be found on the first floor of Zurn Science Center. Graduated Cylinders: A graduated cylinder will be used to verify the porosity for each scaffold after 3D printing and before compression testing.

Outcomes: This study evaluates the effects that the porosity of an osteoconductive scaffold cube has on its mechanical strength. It is vital to understand how a cube’s porosity, which influences bone ingrowth, is related to its strength; the function of macroscopic pores in osteoconductive scaffolds are dependent on these factors. Understanding the relationship between porosity and strength is important in order to optimize the properties of an osteoconductive scaffold.

Title: The Effects of Varying Percentages of Circular Porosity on the Mechanical Strength of Osteoconductive Scaffolds Abstract: Osteoconductive scaffolds promote bone cell growth by allowing for the ingrowth of bone within the scaffold to form a strong network. Because these scaffolds are porous and the relative porosity impacts the overall strength of the structure, determining the ideal geometry and porosity that both maximizes strength and the allowance for bone ingrowth is crucial for successful outcomes. To analyze this relation, this research focuses on the effects that the porosity has on the strength of the scaffold, specifically using spherically shaped pores. Using a compression testing machine, the performance of varying 3D printed porosity percentages will be assessed.

Nurses would make medical errors. The Canadian Centre for Occupational Health and Safety states that fatigue affects performance by the reduction in the ability to do complex thinking, attention and vigilance, ability to handle stress on the job, reaction time (both speed and thought), ability to recall details, stay awake, etc. All of these can affect the decision-making ability of nurses (Twarog, 2011).
Summary of State Mandatory Overtime Regulations
Types of Regulation Categories
The physical and mental health of nurses gets badly affected. A study was conducted to find the relationship of work hours, mandatory overtime, and on-call to musculoskeletal problems in nurses. It was found out that there was an increase in the risks of musculoskeletal diseases (MSD) with an increase in mandatory overtime, working more than 13 hours per day, working on off-days, working on weekends, or off-shift. The increase in the risk of MSD was explained not by psychological demands, but by the physical demands of the job. Working long hours without sufficient breaks can negatively affect nurses’ health (Trinkoff, 2006).
Why is mandatory overtime still legal in some states?
Restriction on total work hours per day or week

Problems caused by mandatory overtime
According to the Academy of Medical-Surgical Nurses (AMSN), when nurses work for more hours than was specified in their contract (usually 40 hours per week), it is called mandatory overtime. This is used in case of emergencies, however, in recent years the overtime rates of nurses have increased drastically and is causing a lot of problems.
Nurses would burn out due to exhaustion. Working for more than 12 hours at a stretch can cause exhaustion in nurses, which in turn has some serious side effects which can affect their mental and physical health. Due to exhaustion, the care given to patients may not be of good quality. A journal article was written examining the correlations between unmet nursing care needs (care left undone) and nurses' reports of adverse patient outcomes. It was found out that there was an increase in adverse patient outcomes (Lucero, 2010).
•
Nurses leaving their jobs and causing a shortage of nurses. Due to the mandatory overtime, a lot of nurses are leaving their jobs mostly for the sake of their own mental and physical health.
•
The staff morale would reduce. In the American Nurse Today, a journal of the American Nurses Association, Marcia Faller had said that as nurses are forced to work more hours than was decided on in their contracts, there are risks of becoming tired, stressed, or resentful and eventually leading to a decrease in morale and job satisfaction (Faller, 2008).
(American Federation of Teachers, 2020)
Solutions •
Hospitals planning for their nurse staffing strategically. Marcia Faller had argued that the need for mandatory staffing can be reduced if the hospitals plan their staffing needs strategically. According to her, clinics and hospital managers should understand the reasons for low retention rates and address them (Faller, 2008).
• Making mandatory overtime voluntary and better working conditions. One way to address the low retention rates is to improve the working conditions and offer mandatory overtime on a voluntary basis. Better working conditions like higher pay, shorter working hours, or offering extra assistance via managers can increase retention rates and eventually reduce the need for mandatory overtime.
• Hiring travel nurses with temporary contracts for staffing shortages. An easy and effective way to deal with staffing shortages is to hire travel nurses temporarily. This would ensure that the patients are given quality care without the need for the regular nurses to work overtime (Mandatory overtime in nursing: What you need to know, 2018).

THE REBIRTH OF SLAVERY IN LIBYA Chrinesse Mpunga (Legal Studies) Mentor: Att. Peter Agresti ABSTRACT
DEFINITIONS Modern Slavery: The condition of being forced by threats or violence to work for little or no pay and having no power to control what work you do or where you do it. This includes, domestic slavery, forced sex work and forced participation in crime. Crimes Against Humanity: Acts when committed as part of a widespread or systematic attack directed against any civilian population with knowledge of the attack.
Slavery in Africa began as early as the 14th Century when African people were taken as slaves and transported to different parts of the world. As the world evolved , many African nations seemed to have experienced what was illustrated as freedom from falling victim to slavery. To many people around the world , slavery is an ancient idea that occurred many years ago. It has been proven that slavery continues to occur in the African continent specifically, in the nation of Libya. My research focuses on, how the rebirth of slavery in Libya can be classified under the Crimes Against Humanity ? To address the question, I conducted research on the definition of Crimes Against Humanity according to the Rome Statue of International Criminal Court. In addition, I research the legal measures that have been taken to terminate the ongoing slavery in Libya and punish all parties involved. • • • •
Reasons of Displacement • • • •
Forced displacement Unmanaged migration Persecution Migrant desire to get to Europe
CONTRIBUTING FACTORS Facilitating Factors • • • •
Failed government Increased poverty rates Increased corruption and terrorist groups Migrants have come an economic support
CRIMES AND ACTIONS • 2017 CNN recorded video evidence of a human auction in Libya, witnessing men being sold to other slave owners for hard labor at a low price • Women and children sexually assaulted and trafficked to other nations and conducting sexual slavery • Forced prostitution • Corrupt government officials fund terrorist groups conducting slave trade to evade capture by law enforcement
TARGETED VICTIMS Migrants fleeing from their home nation in hope of reaching Europe. Trafficked persons Men, women and children AGGRESSOR Libyan terrorist groups with the aid of corrupt government officials
ROME STATUE INTERNATIONAL CRIMINAL COURT VIOLATIONS Article 5: Crimes within the jurisdiction of the court • Crimes Against Humanity Article 7 : Crimes Against Humanity • Enslavement • Sexual violence • Deportation of forcible transfer of people • Inhuman acts causing, serious injury to body or mental health • Torture Article 29: Non-applicability of statue of limitations • Crimes within the jurisdiction of the court should not be subjected to statue of limitations. Article 109: Enforcement of fines forfeiture measures
CURRENT ACTIONS • Rwanda and Niger have opened their borders to migrants and refugees in Libya • EU has financed and trained Libyan authorities on how to stop illegal migration of persons to Europe through the Mediterranean sea. • EU has funded the International Migration Organization to help migrants stranded in Libya get back home • Parties and persons identified to be part of the slave trade have been imprisoned
SUGGESTED ACTIONS • Severely punish persons and parties that have offered terrorist group the aid to conduct slavery trade and evade capture. • Impose stricter economic sanctions on Libya • Offer reward in exchange of information regarding slave trade and auctions • Help Libya establish political stability that can lead to more legal structure. • Increase the presence of the United Nations Refugee centers in Libya for migrants to seek refuge • Implement an accelerated plan to transport migrants out of Libya to refugee host nations
CONCLUSION There are many factors both voluntary and involuntary that contribute to why people migrate from one location to another. These factors have facilitated to the contribution of the rebirth of slavery. In addition, the collapse of the Libyan government serves as the foundational cause of the rise of slavery. According to the Rome Statue of International Court, all the heinous crimes committed in Libya befit the definition of Crimes Against Humanity. There is overwhelming evidence that depict the extent at which the statue has been violated. There are four articles in the Rome Statue that address the crimes against humanity by definition. In efforts to combat the ongoing slavery in Libya, many actions have been taken by the United Nations and by other nations. Some parties involved in the slave trade have been punished while other parties are yet to face the consequences of their actions. In order to hold such parties accountable, it will require the efforts of the United Nation as well as nations around Libya. Therefore, the suggested actions can be taken to in order to find more permanent solutions. REFERENCES

As the world evolved and developed, many African nations seemed to have experienced what was illustrated as freedom. The freedom from being enslaved and never to be repeated again. To many people around the world, slavery is an ancient idea that occurred many years ago. It has been proven that slavery continues to occur in the African continent, specifically, in the nation of Libya. The collapse of the Libyan economy, political instability, and migrant crisis served as the fundamental causes of the rebirth of slavery. Libya has monetarized its transition nation, for migrants attempting to reach Europe in pursuit of better opportunities. Libyan terrorist groups are at the forefront conducting these inhumane crimes with the aid of corrupt governmental officials. They are conducting activities such as, auctioning fellow human beings, enslaving and sexually abusing migrants. My research focuses on, how the rebirth of slavery in Libya can be classified under Crimes Against Humanity? To address the question, I conducted research on the definition of Crimes Against humanity according to the Rome Statue of International Court. In addition, I researched what legal measures that have been taken and to terminate the ongoing slavery in Libya and punish all the parties involved.

The Role of trans-Golgi Network and Endosomal Adaptors in Nitrogen-Regulated Growth of Saccharomyces cerevisiae Biology Department, Gannon University , Erie, PA 16501
Abstract
Introduction
Trafficking of a variety of proteins between the cell surface, trans-Golgi network (TGN), endosomes, and vacuole is regulated by clathrin adaptors. In this study, we focused on the role of the TGN-endosomal clathrin adaptors on the nitrogen-regulated growth of Saccharomyces cerevisiae. We hypothesized that distinct combinations of adaptors may regulate nitrogen permease trafficking under different nitrogen conditions, leading to distinct effects on cell growth. To discern the role of clathrin adaptors in nitrogen-regulated growth, we have constructed various clathrin adaptor deletion mutants and tested their effects on growth in preferred and non-preferred nitrogen sources. Growth assays were performed to compare the differences in growth rate in mutant vs. wild-type cells. Our results show that these clathrin adaptors’ role in cell growth is not linked to their function in regulating specific nitrogen permeases and suggests a more general function in cellular processes that may affect metabolism and/or cell cycle regulation.

Current Results
To optimize cell growth, yeast regulate the gene expression and transport of nitrogen permeases to selectively take up more preferred nitrogen sources such as glutamine and ammonium before taking up the less preferred nitrogen source proline. Post-transcriptionally, cell signaling pathways modulate the expression of these permeases by regulating their trafficking to, from, and between the trans-Golgi Network (TGN), plasma membrane, endosomes, and vacuole [1]

Our results show that overall, the triple deletion in preferred (NH4) and nonpreferred (glutamine and proline) nitrogen sources had the greatest defect [C]. The ent3∆∆ent5∆∆ mutant had a growth defect [B] compared to the other two double deletions that was not hypothesized. This suggests that Ent3 and Ent5 are more important than previously thought and deleting them together has a growth defect. These results suggest that Ent3 and Ent5 are functionally redundant and complementary to Apl2 function, and that cell growth requires Apl2 and Ent3 or Ent5. Moreover, these clathrin adaptors’ role in cell growth is not linked to their function in regulating specific nitrogen permeases and suggests a more general function in cellular processes that may affect metabolism and/or cell cycle regulation.
Future Studies We plan to shift the focus of our study and look at the general function of clathrin adapors in cellular processes that may affect metabolism and/or cell cycle regulation. To do this, we plan to use our single, double, and triple clathrin adaptor mutants and look into how ATP levels are influenced by the different clathrin adaptor proteins. References: 1.

The United States is cur rently in a 21st Centur y “Tech Cold War” with China, but is it necessar y?
Nicholas Nagy nagy005@gannon.edu
Why Americans be worried
Overview • The United States has been at the forefront of technology innovation for the past four decades, but has recently met a competitor, China. The two global superpowers are now competing in a 21st century “Tech Cold War”, battling to obtain global hegemony and rule the international tech industry.
TABLE I The Basics of the “Tech Cold War” The United States The American government has mixed opinions on its technological priorities resulting in no clear plan or strategy [1]
China The Chinese government invest in technologies with clear and strategic clarity to move closer to their goals [2]
The American government no longer funds research and development to innovate certain technologies Most technological advancement is driven by the consumer preferences since private sectors are now the source of U.S. technology breakthroughs
The Chinese government drives technology innovation priorities through funding
“…promotes free markets, the free flow of information, and freedom of expression” [3]
“…enhancing control of its citizens’ economic and personal decisions, monitoring everyday communications and movements, and does not hesitate to promote propaganda or censorship” [3]
The U.S. currently has global hegemony in the tech industry, but is losing that power quickly
China is gaining global hegemony and starting to control certain areas of the international tech industry
Most technological advancement is driven by the Chinese government and influenced by what the Chinese government wishes to accomplish
What Technology are Both Countries Focused On? • Semiconductors – Used in anything that is computerized or implements radio waves. Helps increase conductivity between conductors and nonconductors. • Quantum Computing – Computer that uses quantum mechanics so that it can perform certain kinds of computation more efficiently than a regular computer can. • 5G – A global network that is designed to connect virtually everyone and everything together including machines, objects, and devices.
• The country that wins the “Tech Cold War” will gain global hegemony in the international tech industry which in turn will hurt the other’s technology industry. • “…technology is the key driver of economic growth of countries, regions and cities. Technological progress allows for the more efficient production of more and better goods and services, which is what prosperity depends on” [4]. • If China out competes America consistently in the future, more and more countries will start trading and investing in Chinese technologies instead of trading and investing in American technologies, leading to economic recession. • Economic recession would be prevalent in America if they lose, resulting in high unemployment, falling incomes, and reduced economic activity. The long term effects would impact education, R&D, investments, and skills which would then “undercut the United States’ global competitive advantages” [5]. • Economic trends are already appearing in each country’s GDP, directly mimicking which county is winning the “Tech Cold War” (Figure 1). • It is also worth noting that America made up 24.4% of the world GDP in 2019 and China made up 16.3%. However, America dropped from 30.5% in 2000 while China rose from 3.6% [6]. • America’s national security would be at threat as well if China comes out on top in the “Tech Cold War” because with control of the tech industry, they can impose their views and values in the tech market.
Fig. 3.
Important Steps America Must Take • The government needs to start taking more drastic offensive measures against China, the “America Competes” Act is a great starting point. • More news coverage needs to be dedicated to this subject, without American’s support, the government will never outcompete the Chinese. • It would be in America’s best interest to influence private sectors to move away from innovating technology based on consumers’ preferences and innovate technology with the country’s needs for the future in mind.
Fig. 2. Share of electric vehicles sold in the first half of 2021. Highlighted in blue is an American company and highlighted in red is a Chinese company along with SGMW [10] How America is Fighting Back • The first big blow to China was in 2018 when U.S. restricted the use of military equipment and services from five Chinese information technology companies. • In addition, the U.S. rightfully began to remove untrusted contractors from U.S. IT infrastructure projects and blocked Americans from investing in Chinese surveillance technology companies and companies that worked with the Chinese military [8]. • Following the right direction, some of the U.S. allies proceeded to turn away from China’s big tech firms, blocked inbound investments of Chinese tech, and ceased their semiconductor trade to China. • In 2021, the U.S. government passed the “Innovation and Competition Act” which included “…$52 billion to increase U.S. semiconductor production and authorizes $190 billion to strengthen U.S. technology and research to compete with China” [9]. • Another good offensive move was when America created the “America Competes” act. • The objective of the bill is to create a substantial increase of investment in IC chips, boost U.S. manufacturing and research capacity, and advance U.S. competitiveness and leadership [9]. • In addition to the U.S. government, U.S. private sectors are trying to outcompete China, and fortunately, in some industries, the private sectors are succeeding (Figures 2 and 3).

Title: The United States is currently in a 21st century “Tech Cold War” with China, but is it necessary? Abstract: Two of the biggest economic powers in the world are currently in conflict with one another, the United States and China. The central battleground in this conflict revolves around the advancement of certain technologies. If China capitalizes in advancing first, they have the chance to claim global hegemony for the technology industry and land a devastating blow to the United States’ economy. However, if the United States wishes to succeed in defending its economy and power in the global technology industry, how drastic should involvement be and what measures must be taken?

Abstract
Industrial, and Information Systems Engineering, Gannon University, Erie, PA, USA
Limitations of DHM • Sensitivity to posture. • Deficiencies in currently available data on three-dimensional human anthropometry and strength limit model accuracy. • No clear understanding of the basic principles behind human posture and motion.
• Evaluates the risk of musculoskeletal injuries (MSDs) for caregivers and nurses in the healthcare industry using Digital Human Modeling (DHM) Technology. • 33 subjects underwent two different tasks four times. • Jack was connected to Xsens and a subject’s manikin on Jack was constrained to its corresponding mannequin on Xsens. • Xsens was used to determine the frame number and posture at which the subject exhibited the highest amount of force on the lower back. • Jack was used to analyze the highest Compressive, AP Shear and Lateral Shear force actin on the lower back. • Data were exported onto an Excel sheet. • These data were analyzed to predict the position which can decrease the risk of these injuries at healthcare workplaces.
Why nurses get easily injured? • High frequency of patient handling tasks. • Greater the weight of the patient, higher exertion. • Awkward postures. • Overexertion due to repeated activities.
Two different tasks performed 16 subjects, both male and female, undergo 2 different tasks. • First Task - subject moving the mannequin from a laying position to a sitting position. • Second Task: Posture One – when the subject bent backwards slightly to lift the mannequin from the bed using both the hands. Posture Two - when the subject bent forward by moving his upper body downwards at an angle approximately 45 degrees from the upright position to place the mannequin onto the chair.
Use of Jack and Xsens Advantages of DHM
•Dynamic simulation to predict human movement, using the Task Simulation Builder. •Simulate biomedically accurate digital humans of various sizes in virtual environments, assign them tasks and analyze their performance. •Delivers results as realistic as using real users within a short time. •Bridges computer-aided engineering designs, human factors engineering and specified ergonomics.

• Xsens was connected to Jack Siemens software by a network server. • Xsens mannequin was opened, and the corresponding Jack manikin was opened simultaneously. • Constrains are added onto both pairs on Xsens and Jack. • Human Control Panel window was opened. • Xsens MVN video was played till the appropriate pose frame number was reached. • Different data analysis was done at that specific pose. • The lifting hand force required to reach 3400N for Compressive force, 1000N and 700N for AP Shear force were analyzed. • These are the minimum force numbers that can be reached by a caregiver to avoid risk of injuries.
Lower Back Analysis on Jack • Each task had four trials and for each trial, four different data analysis were done. Depending on the analysis, the variables measured were Hand force, AP Shear, Compressive and Lateral Shear force. For the regular analysis, Trunk Flex, Right
Hip, Left Hip, Right Knee, and Left Knee forces were also recorded.
• Task 1 – Regular analysis where the hand force, only right palm center = 70N For both right and left palm center: Compressive force to reach 3400N, AP Shear force to reach 1000N, AP Shear force to reach 700N • Task 2 – Regular analysis where the hand force, left and right palm center = 125N For both right and left palm center: Compressive force to reach 3400N, AP Shear force to reach 1000N, AP Shear force to reach 700N
Future of nurses with MSDs • DHM in conjunction with Xsens can determine the hand forces which lead to the maximum lower back forces. • Predict the position that caregivers must avoid while working. • Determine the posture and movements that can help decrease the risk of WWDs. • Help decrease the risk of musculoskeletal injuries and improve the healthcare industry. • Improve the performance of nurses and reduce the percentage of healthcare workers leaving the industry. • Increase the efficiency of the health industry, to improve the health of the public. • DHM will continue to greatly impact the health industries as well as other industries.

Providing the customer with an efficient and reliable product is extremely important in satisfying the customer’s needs. A home owner will want their product to consume the least amount of power necessary so their utilities bills do not significantly increase. Also, customers will want their product to function properly and destroy harmful airborne particles. Another appealing customer need is for a simple and easy setup and use. Easy setup would save the customer time and limit the chance of misuse or improper setup. Another major need for this product is to maximize the life span of the filter and UVC lights.

Title: UVC Air Purifier Abstract: Air quality inside residential homes is very important in keeping the people who live there healthy. Air purifiers can reduce the chances of respiratory infections, eliminate harmful airborne particles, and neutralize unpleasant odors. Short wave ultraviolet light (UVC) air purifiers are an effective method to ensure proper air quality. However, most UVC air purifiers for residential use currently are misleading and not very effective. We are designing a UVC air purifier that will be able to ensure and maintain proper air quality in an office or residential space, while also being efficient, easy to use, and cost effective.

INTRODUCTION
Latent heat thermal energy storage (LHTES) systems utilize a phase change material (PCM) to store thermal energy transferred by a heat transfer fluid (HTF). The ability of LHTES systems to retain energy makes them useful in applications that include concentrated solar power, waste heat recovery, and food drying.
MATERIALS AND METHODS
Rubitherm RT-55 was the PCM. The experimental apparatus is shown in Fig. 3.
RESULTS AND DISCUSSION
The processing times for HTF inlet temperatures and flow rates studied are shown in Table 1 and 2.
Fig. 5 and 6 show the energy response for the charging and discharging processes.

Fig. 1 Food dr ying using LHTES (Bhagwat et al. 2017)
Passive heat transfer enhancement techniques, such as fins, are needed to increase the heat transfer rate within the system [1]. This study assessed the effect of variable HTF properties on the charging and discharging time of a thermal storage unit enhanced with annular fins through a comparison of total charging or discharging time and the energy response of the system.
The flow rate of the HTF was measured in gallons per minute (gpm) using a flow meter. The inlet and outlet temperatures of the HTF were recorded using two RTDs. The HTF flowed through a copper pipe with ten annular fins attached (Fig. 2) which was located at the center of the PCM chamber. The temperature of the PCM was measured with twelve k-type thermocouples. The experiments were conducted at room temperature. Charging cycles were tested for HTF flow rates of 1, 2 and 3 gpm at temperatures of 65° C and 70°C. Discharging cycles were tested for HTF flow rates of 0.5, 1, and 1.5 gpm at temperatures of 20°C and 15°C. Thermal and regular images were taken at specific time intervals to track the melting and solidification of the PCM.
Thermal images track the differences in the charging process for 65°C at 1 and 3 gpm (Fig. 4).

A benchmark case with no fins took 47.87 hours to charge and 42.5 hours to discharge. The best HTF properties decreased charging and discharging time by 84% and 74%, respectively, compared to the benchmark. The charging and discharging times for each HTF inlet temperature decreased as the HTF flow rate increased. The inlet temperature of the HTF has a larger impact on decreasing charging and discharging times than the flow rate.

Title: Varying Heat Transfer Fluid Properties in a Latent Heat Thermal Energy Storage System Abstract: Latent heat thermal energy storage (LHTES) systems are becoming increasingly useful due to their high energy storage density and nearly isothermal operation; however, the thermal conductivity of common phase change materials remains low. Passive heat transfer enhancement techniques have been heavily studied, but the effect of heat transfer fluid (HTF) parameters on the thermal performance of LHTES systems have not. In the current study, the effect of variable flow rates and inlet temperatures of the HTF during the charging and discharging processes of a LHTES unit enhanced with annular fins is experimentally evaluated.

Water quality and microbial diversity in Lake Pleasant, Union City, PA Physical, chemical and nutrient analysis in a local, glacial lake
Abstract
Abigail Palotas palotas006@gannon.edu
Future Directions
Experimental Design
Eukaryotic organisms contain mitochondria, organelles which generate ATP through aerobic respiration. These mitochondria likely developed from free-living bacteria which were endocytosed by a eukaryote and then lived within it (i.e. endosymbiotic theory). However, not all eukaryotes live in environments rich in the oxygen necessary for aerobic respiration, yet they must still generate ATP in order to carry out their metabolic functions. Recently, a bacterium which uses nitrate rather than oxygen as the final electron acceptor in its ETC, was found living symbiotically within an anaerobic ciliate in a lake in Switzerland. Perhaps such an organism could be found in our local Lake Pleasant (Union City, PA). We collected water samples at various depths in September 2021, when the lake was stratified. Oxygen was available (> 2 mg/L) down to 6 meters, suggesting that anaerobic bacteria may be present near the bottom of the lake. Water samples were filtered through 0.2 µm filters to collect bacteria. We will then sequence the eukaryotic and prokaryotic genomes on the filters to determine the overall microbial signature at each depth. Microbial data can be compared to water quality data that was collected during sampling. In doing so, we might find hints of nitrate-utilizing endosymbionts reminiscent of Swiss lake systems.

Some lakes, such as Lake Pleasant, undergo a cycle of stratification. The distinct layers of the lake, the epilimnion, metalimnion, and hypolimnion, fully mix during fall and spring but stratify during the summer due to differences in temperature caused by heating from the sun which warms water at the surface of the lake much faster than water in deeper parts of the lake. Warm water’s lower density allows it to remain above the cooler, denser water below. As summer turns to fall, surface waters cool and sink, causing mixing of the layers. The water in the entire lake will eventually reach the same temperature and density, and the lake will no longer have distinct layers. However, as winter turns to spring, the sun will heat the lake, once again creating temperature and density differences allowing for stratification. Different microbial species might seasonally oscillate with lake stratification.

Wesleyville Population by Gender, Age, and Race
Alexis Bruscemi, Nicole Buckman, Skylar Flanigan bruscemi001@gannon.edu, buckman002@gannon.edu,flanigan003@gannon.edu
Abstract: Using GIS and data from the US census, this research examines the spatial distribution of Wesleyville population in 2019. The research examines how population varies by gender, age and race. Wesleyville is a small borough outside of the city of Erie that has an approximate population of 3,400. The research on population distribution of Wesleyville supports current efforts to obtain funding for the revitalization of the community. The research also updates and informs the public on the current state of population in Wesleyville. The data obtain and analyze in this research will also assist in locating sectors of population that need immediate support.
Age: Within the age maps they were combined data of five age group blocks. All of the following data was observed by comparing the population to the total population of the area. For the age ranges of 20-29, 30-39, and over 85 they were largely represented in the central core of the map. The age ranges that were most found in the top section of the map included to be under 5, 40-49, 50-59, and 60-66. The only age group when looking at individual groups the 10-14 age range was the only prominent population in the bottom section. However, when compared to the sum of each of the age groups combined shown in the maps most of the population is in the center section for under 5 to age 49 as well as ages 50 to over 85. Throughout the data collection, there were more younger populations than older populations within the area. This data indicates that the ages within the borough that when looking at individual age groups they are more prominent in top sections where as the sum of the groups are in the middle central core. This signifies that the overall age groups reside in the central core of the borough.
Analysis of each map: Race: These maps show the population in Wesleyville by race. There are six different maps that represent white, black, Asian, American Indian and Alaska Native, Hawaiian, and other populations. These maps show that Wesleyville is predominately white, and the most populated block of this borough is the middle block. The population of black, Asian, and other races have very similar maps, which show that they have similar population in each block. There are very few American Indian, Alaska Native, and Hawaiians in Wesleyville.
Conclusion and Recommendations: Wesleyville is a small community on the outer parts of Erie, Pennsylvania. Throughout these maps, we can see that the borough is a diverse area where the population is not as spread over the three sections. The central core of the borough is where we see the most population where we would suggest would need the most revitalization toward their community. Within all of the maps, in that central core there we see the different races, ages, and genders are located there. Our recommendations would include to focus on getting funding for that area due to it being the most populated.
Gender: In these two maps you can see the population by gender in Wesleyville. They look identical but what set them apart is the number of males than females (total male: 1028 and total female: 911), but the values vary on each map. In the least populated area, there are more females than males, but the other two areas have more males than females. The least populated is from Pearl Avenue to Buffalo Road, the second most populated is Euclid Boulevard to East 33rd Street, and the most populated if from Buffalo Road to Euclid Boulevard.

What can Businesses do to Eradicate Poverty in Erie? Poverty Percentage and Erie Startup Support
Abstract

Poverty Hotspot and Erie Startup Support
Over the last five years many businesses have shown great interest in the eradication of poverty in the poorest zip code and neighborhood within the City of Erie. This project examines spatial relationship between poverty and business locations in Erie, Pennsylvania. Using GIS and business directory data, the project maps location of poverty and location of businesses. The project discovers how the clustering of businesses intersects within the location of poverty hotspots in Erie. To eliminate poverty in Erie, the project collaborates with the Erie Technology Incubator and Center for Business Ingenuity in creating a business directory guide for early startups in Erie. The business directory will provide a step-by-step guide to startups turning their ideas into businesses. We are hoping that with the directory and through the assistance of CBI’s Beehive the poor neighborhoods will turn to producers and business owner to enable people with limited resources to generate more income to meet their daily needs.
Analyses Beehive Organization The Northwest Pennsylvania Innovation Beehive Network goal is to enhance business development within Erie. Blasco Library, Penn State Behrend, Edinboro University, Gannon University, and Mercyhurst University all provide services to help bring this goal to life.
Poverty Percentage in Erie
Erie Poverty Hotspot
The Gannon Beehive encourages collaboration between business students, entrepreneurs, seasoned business faculty and consultants. The Center for Business Ingenuity at Gannon University work with faculty and students within the Dahlkemper School of Business, the Erie Technology Incubator, and the Small Business Development Center for business planning, development, and advancement in support of the Beehive Network. Specific services this Network provides include advise, marketing, and funding. They work with the growing business to come up with a plan for financial goals and provide support to finalize their product, guiding them to clusters of businesses that can provide aid. The next cluster they look at is to assist the growing business presenting their product as well as comparing it to other similar ideas. The product may then be able to gain a crowd funding appeal, through the analysis of the Beehive.
Using data from the Census database we were able to create a map highlighting the specific rates of poverty. The darker the area on the map the higher to poverty percentage is. The highest areas of poverty are located in the downtown Erie area. Google
Again using the Using Census database we were able to construct another map which now demonstrates the hotspots of poverty throughout Erie. Blue represents areas of higher wealth, grean is a more neural zone, and red demonstrates poverty. Poverty is mainly located in the northern section of Erie, with it highest percentage being around 90% in the central downtown area.
Working alongside the Beehive, we were given a list of businesses that they work with to help aid in their goal to support startups. These businesses are demonstrated in two of the maps, one highlighting poverty percentage and one for poverty hotspots. They are all mainly centralized around the Beehives office, located in the CBI at Gannon University on State Street (the downtown area). After constructing our maps using data provided by the Northwest Pennsylvanian Innovation Beehive Network and the Census database we were able to analysis the relationship between businesses and poverty. The specific businesses used in this project were those that help support startups. The businesses were located in the midnorth part of Erie. Wealthy areas were located in the southwest region of Erie. Comparing the businesses to poverty levels we see that the location of the support businesses are located within the area where poverty is most prevalent.

What Would Happen if the Equal Rights Amendment Were to be Ratified? Overview
In the recent years, the ratification of the Equal Rights Amendment has come back from the 1980s and has caused a great argument if it should be ratified or not. This poster is a pros and cons list of the its passage.
History
• Equal Rights have been a tough battle for women to earn throughout history. • Women’s rights were first brought into Congress in 1923 by Alice Paul and the National Women’s Party, which she had founded. (Bachiochi, 2021). • The ERA was ratified in the 1970s with the Civil Right Movement that allowed women to vote. • The #MeToo movement had rekindled another push for the ERA to be ratified after the 1982 ratification deadline had surpassed in 2018. • Congress had created a rule that the ratification needs three-quarters of states votes. Virginia was the 38th state to ratify the ERA in 2020 which allowed it to reach the ¾ rule. (Bachiochi, 2021).

grebiner001@gannon.edu
People Against the Passing of the ERA Say:
• Abortion laws and maternity-leave policies that are currently in place can be overturned and allow women to have abortion anytime during her pregnancy and could take away maternity leave in general. (Forde-Mazruli, 2021). • “ERA advocates have been unequivocal about their support for abortion and using the ERA to overturn pro-life laws...” Rep. Vick Hartzler (R-Mo.) (Pros and Cons of the Equal Rights Amendment: Equal Protection VS. Safeguarding Anti-Abortion Laws, 2022). • Many say that women's equality is already protected under the Equal Protection Clause. • The ERA would apply to discrimination of federal and state actors, not local companies and private businesses. • The government would have to ignore laws that were made to benefit women. • If there were recognitions for women in STEM, medical, or in business (as those are low percentages of females) they would have to be removed. • All ideas that are sexually categorized (schools, sports, bathrooms, prisons, and military quarters) would become single-sex and would be shared by both men and women. • The Family and Medical Leave Act would be challenged as it would be pushing the laws and would then "discriminate" men (Forde-Mazruli, 2021).
People For the Passing of the ERA say:
• The purpose of the ERA being ratified is to allow women to have equality amongst men. (Forde-Mazruli, 2021). • It would be a major step to end sexual discrimination everywhere. • There would be guaranteed protection to all people no matter what the state legislation says. • Women would have equal pay with men and the wage gap between sexes would be eliminated. (Katsaroumpas, 2021). • When a white man earns a dollar, a white female earns only seventy-nine cents of that dollar, and it is even less for minority women. (Gagnon, 2022). • Women would be allowed to be drafted within the military in times of war and emergencies. • The 14th amendment does not promise the protection on the discrimination of sex where if the ERA were to be ratified, there would be a protection based on sex. • Both men and women would have the same equal responsibility for owning a home where they split the income to pay for one-half of the bills. • Honorary Justice Ginsburg had a primary achievement of allowing women to be equal with men in the Constitution (Forde-Mazrui, 2021).

Title: What Would Happen if the Equal Rights Amendment Were to be Ratified? Abstract: The Equal Rights Amendment (ERA) passed in 1972, but it has not been enacted due to delayed ratification by the states and some states withdrawing their ratifications of it. Sexual discrimination is not prohibited in the Constitution, so there is inequality with genders in many situations such as in unequal pay and in divorced parent custody cases. With the recent #MeToo Movement in the past few years, a debate has sparked since the 1970s regarding the ratification of the ERA. However, if the ERA were to be ratified, what rights would women gain and what rights would men lose? Presenter(s): Lexyannah Grebiner Sponsoring Department: English Project Mentor: Ann Bomberger

Introduction
Figure 3. Distribution of Ebolavirus Outbreaks in Africa Since 1976, outbreaks have been localized to West and Central Africa, with Sierra Leone, Liberia, Gabon, Congo, Democratic Republic of the Congo, and Uganda being hit the hardest by the “Caregiver’s Disease.” This map also shows the distribution of species of Ebolavirus, with Zaire Ebolavirus overtaking all other species, followed by the Sudan species. (CDC, 2021)
Ebola hemorrhagic fever is an exceptionally fatal disease in humans, up to 90% lethality when caused by the most virulent strains of Ebola virus. A recent Ebola epidemic occurred in West Africa from 2013 to 2016 and included nearly 30,000 infected persons, with over 11,000 confirmed deaths. Ebola virus carries an antisense singlestranded RNA (-ssRNA) genome that is 19 kb in size and encodes just 7 viral proteins. Currently, there are three globally approved Ebola vaccines, with six others in various stages of development. Everbo was the first FDA approved Ebola vaccine that expresses the full-length GP from the virus, followed by Zabdeno/Mvabea two shot vaccine with human adenovirus expressing Ebolavirus and an attenuated poxvirus, and lastly Ad5-EBOV which also uses human adenovirus.

Figure 4. The Progression of Symptoms Ebolaviruses cause hemorrhagic fever, a disease that leads to not only the inability of blood to clot, but can also cause blood vessels to rupture. This causes the bleeding out of all bodily orifices that is commonly shown in the media. Other severe symptoms include diarrhea and vomiting that lead to a severe dehydration. Catching the early symptoms is key to survival.

Results
Here we showcase our own RNA vaccine design using evolutionarily-conserved peptide sequences derived from reference sequence submissions of Ebola variants into NCBI. The regions that were added in addition to the coding region were replicated after the Pfizer novel SARS-Co-2 mRNA vaccine.
Figure 1. The Viral Lifecycle of Ebolavirus Inside a Human Cell
Infectious Ebola virions are enveloped and adhere to target human cells via viral glycoprotein (GP) interactions with a wide variety of human target proteins. Entry into the cell occurs via either macropinocytosis, clathrin-mediated endocytosis, or caveolinmediated endocytosis. (Hoenen, Groseth, Feldmann, 2019)

Design and Implementation of a Low-Cost Plant Growth Chamber that Permits Video-Timelapse Recordings of Root Systems
Abstract
1Dept
Chamber Design and Manufacturing
Previous work on time-lapse imaging of plant roots have yielded amazing insights into the rapid kinetics of the secondary messengers involved in growing roots. Although, such experiments can be costly. Here we describe efforts in implementing an alternative, lowcost Raspberry PiCAM for imaging root growth in the fern, Ceratopteris richardii. Our imaging system provides anatomical recordings of developing roots in custom-built growth chambers. The root growth chambers are constructed of laser-cut clear acrylic panels of dimensions dictated by on-site temperaturecontrolled plant-growth incubators. The imaging system allows us to control all aspects of the root growth experiment, such as the precise nutritional composition of the growth media as well as the presence of bacterial and fungal species known to impact root growth in plants. The process from design to implementation of both the root growth chamber & the PiCAM imager, is estimated to cost ~100-fold less than existing TLFM approaches.

TLFM in the model angiosperm Arabidopsis thaliana permits exceptional visualization of small messenger molecules employed in root growth. Additionally, video recordings of pea plant root development (Pini et al., 2018) across a 3-week period display elaborate growth patterns. Pea plants can form symbiotic relationships with soil microbes that influence this angiosperm’s root development. Most plant root studies are centered on seed plants (angiosperms).

Plant Root Evolution and Imaging
The evolution of land plants is an approximately 500million-year-old saga. Roots evolved independently on two separate occasions: the lycophyte lineage and in the lineage giving rise to monilophytes (ferns) and all seed plants (gymnosperms + angiosperms). Within these extant lineages, a variety of various root systems sustain the numerous, colonized ecological niches of plants, particularly evident in the angiosperms.

A Census of the Bat Population of Gannon University, Erie, PA
Title: A Census of the Bat Population of Gannon University, Erie, PA Abstract: For the past eleven summers, a census of the bat population has occurred on the Gannon University campus in Erie, PA. The numbers for the first three years held relatively steady, but the data for the past eight years indicates a dramatic decline. White Nose Syndrome has killed an estimated 7 million bats in the eastern United States since then and has spread throughout Pennsylvania and into northeastern Ohio. This fungal infection has killed 95% of bats in some caves and may result in the listing of three bat species as endangered in Pennsylvania, including Myotis lucifugus, the predominant bat on campus. This study will compare yearly data by building, time of year, building side, and species composition to determine how White Nose Syndrome has affected the Gannon campus bats. The results will also be used to place bat houses at appropriate locations to encourage bat presence on campus. Presenter(s): Sarah Till Sponsoring Department: Biology Project Mentor: Steven Ropski

A Study of Insect, Plant and Mammal Diversity on Two Green Roofs of Differing ages on the Campus of Gannon University
Title: A Study of Insect, Plant and Mammal Diversity on Two Green Roofs of Differing ages on the Campus of Gannon University Abstract: This research project explored the advantages of having a green roof at Gannon University in relation to insect, plant, and small mammal diversity. Green roofs are designed to provide a natural environment for various insects and potentially mammals. Insect diversity was measured using fly ribbon on wooden stakes for an aerial setting and laid on the green roof surface for ground. Fly ribbons were also placed in a neutral grass area at ground level for a control. Sherman small mammal live traps were set. This was done over a three-day period through the months of September and October. The green roofs had an abundance of different plant species including indigenous and invasive. This project allowed us to investigate the benefits of green roofs and discuss the positive effects on the ecosystem.

Brood pouch microbial diversity associated with maternal and juvenile Japanese Mysterysnails
Title: Brood pouch microbial diversity associated with maternal and juvenile Japanese Mysterysnails Abstract: Bacteria associated with animals are involved in critical functions of their hosts, including nutrition, behavior, immune responses, and development. This has been demonstrated in snails as well, where gut microbes are ubiquitous contributors to many physiological processes. Multiple factors are known to influence the composition and function of the animal microbiome; diet, geography, seasons, and disease are all shown to cause variation in and potential disruption of an animal’s flora. Cipangopaludina japonica, the Japanese Mysterysnail, is a widely introduced snail across the U.S. Mysterysnails belong to family Viviparidae, freshwater snails that brood their young before releasing live juveniles. We explored the microbiome associated with C. japonica brood pouches and described the bacterial diversity of the maternal and juvenile environments. Preliminary data suggest that bacterial gradients exist within the brood pouch, and that microbial diversity increases in a proximal to distal fashion.

Designing a Water Treatment Plant to Address Rural Community Needs
Title: Designing a Water Treatment Plant to Address Rural Community Needs Abstract: Most rural communities get their drinking water from wells; this water is generally more susceptible to corroding pipes, aging infrastructure, contamination from septic tanks, and fertilizer and manure contamination from farm land. With outdated infrastructure, growing population demands, and emerging contaminants, Pennsylvania has become an area of concern in terms of water treatment and distribution systems. A water treatment plant will be designed using Northwestern Erie County communities not under the service of Erie Water Works as a case study to address these issues. Designing a modern water treatment and distribution system would improve drinking water quality for the growing population in the service area. The design will draw water from Lake Erie and address cost, maintenance, performance, sustainability, and cyanotoxin contamination. In addition, a tabletop-model of the rapid mix, flocculation, and sedimentation processes will be designed using Creo software and will be constructed with acrylic and 3D-printed parts.

Factors Affecting the Cargo Delivery within Supramolecular Hydrogels
Title: Factors Affecting the Cargo Delivery within Supramolecular Hydrogels Abstract: Supramolecular hydrogels can be utilized as biomaterials for the controlled release of drug molecules via cargo delivery. In this case, low molecular weight gelators form the supramolecular hydrogels. The three derivatives studied are Fmoc-Phe-OH, Fmoc3F-Phe-OH, and Fmoc-F_-Phe-OH. These Fmoc-amino acids are capable of forming hydrogels that can encapsulate various cargo. Two different methods were used to form the hydrogels because, from previous studies, different methods lead to more stable hydrogels. A variety of cargo molecules were used to test the ability of the hydrogel to form in the presence of the cargo and further to examine their ability to enter or release from the hydrogel. Both D and L amino acids have proven to have similar gel stability, cargo release rate, and overall properties. We are currently studying how other factors affect the rate of diffusion within different combinations of gels and cargo molecules, such as charge to charge interactions, size of cargo molecules, and pH.

Feasibility Study to Implement Solar Panels at Gannon University
Title: Feasibility Study to Implement Solar Panels at Gannon University Abstract: The overall goal of this project is to evaluate the feasibility of implementing a solar energy system to the Gannon campus. Our plan is to survey university buildings across Gannon’s campus and determine which of those would be optimal in implementing solar panels. This evaluation will include an aerial imaging survey of university roof tops, an estimate of solar radiation on campus, and the amount of electricity produced per climate conditions in Erie, PA. Through our research and data analysis we plan to determine the feasibility of utilizing solar radiation to supply electricity to devices within a specific building on campus. The presentation of this feasibility study will include summaries of: estimates of solar radiation, energy produced, costs, funding sources, and how to display information for educational purposes on Gannon campus. This project aligns with the overall goals of the Erie 2030 district of which Gannon is a participating member of.

Green Synthesis and Analysis of Potential Antibacterial Copper Nanoparticles
Title: Green Synthesis and Analysis of Potential Antibacterial Copper Nanoparticles Abstract: Development of ecologically friendly methods for metal nanoparticle synthesis is at the forefront of current research efforts, including use of plant extracts as green reducing agents. Copper nanoparticles will be synthesized using Spinacia oleracea (spinach) leaf extract as a reducing agent, as related plant species have been shown to reduce copper(II) ions to copper nanoparticles. Metal nanoparticles have shown promise as potential antibacterial agents in medical implant coatings, wound care materials, and antibiotic delivery tools. Therefore, the potential antibacterial properties of the synthesized copper nanoparticles will be investigated against Escherichia coli using disc diffusion method. It is expected that if the synthesized copper nanoparticles exhibit antibacterial activity the zone of inhibition will show a concentration dependence; namely, the zone of inhibition will increase with an increase copper nanoparticle concentration.

Minimal Configurations of Points on Closed Curves
Title: Minimal Configurations of Points on Closed Curves Abstract: It is common knowledge that two point charges of the same polarity repel each other. Drawing inspiration from this concept, we define the energy between two points in R^n to be inversely proportional to the square of the Euclidean distance between them. By restricting points to a closed curve, we can pose the question: Which configuration(s) minimize the energy between points? We examine curvature, convexity, arc length, and other properties of closed curves and their interaction with these minimal configurations, and we provide examples illustrating notable results.

Synthesis of Lanthionine Sulfoxide Isomers
Title: Synthesis of Lanthionine Sulfoxide Isomers Abstract: Mycobacterium is a genus known to contain many pathogenic bacteria such as Mycobacterium tuberculosis, responsible for causing tuberculosis in humans. Over the course of treating these diseases with various antibiotics, Mycobacterium have developed antibiotic resistance. One biochemical pathway used by Mycobacterium involves the synthesis of the amino acid lysine. This pathway is not utilized in humans and can be potentially exploited to target Mycobacterium. The enzyme lysine synthase is used in this pathway and is predicted to be inhibited by lanthionine sulfoxide. Our goal is to optimize the synthesis for lanthionine sulfoxide in order to test its potential antibiotic properties on Mycobacterium smegmatis, a sister species to M. tuberculosis. Once the procedure is optimized, we will isolate stereoisomers of lanthionine sulfoxide to determine if one isomer is more effective. The products of the synthesis will be confirmed with nuclear magnetic resonance, mass spectrometry, and infrared spectroscopy Presenter(s): Devin Williams, Nikolas Guerriero Sponsoring Department: Chemistry and Biochemistry Project Mentor: Christine Saber

When a Duck Nests on Your Green Roof
Title: When a Duck Nests on Your Green Roof Abstract: When a curious waterfowl discovers a green roof, the possibilities are endless. Located atop Gannon University’s Nash Library and Student Learning Commons, is a 4-year-old green roof. On May 23rd 2021, a nesting mallard was discovered during a routine clean out of the plant beds. With green rooves bringing nature closer than ever a mother mallard chose the area three stories high with no water source as her nest site. The nest, built only 3 ft away from the large window, resulted in almost no privacy. Normally nesting mallards choose a site low to the ground, near large water sources and containing multiple hiding places, making this mallard an anomaly. Through the use of video equipment and close observations from the library staff (daily) and researchers (2:00pm- 4:00pm nearly every afternoon) until June 20th, granted the ability to closely monitor the behaviors of the mallard. There were also questions early on about the safety of the young being so high up and without water, which eventually led to the decision to aid in their removal from the roof only 1 day after hatching (with a big help from W.I.N.). While the mallard’s subtle but various behaviors were a primary focus, the idea that animals would make use of a green roof as habitat is significant and not well documented.

OBJECTIVE
Figure 4. Data Analysis Procedures
The aim of this study is to understand physicians' perception of occupational therapy's scope of practice and to identify if perceptions are accurate based on the Occupational Therapy Practice Framework.
BACKGROUND v Researchers found that the most common barriers concerning occupational therapists (OTs) in the primary care setting were uncertainty about funding and what OTs can offer to the primary care team (Dahl-Popolizio et al., 2017) v Occupational therapy services was not acknowledged in acute medical settings. For occupational therapy services to be recognized as dynamic, OTs need to educate individuals on their abilities to promote increased referrals (Elliott et al., 2010) v Using an evidence-based approach to design an educational strategy can increase the knowledge of one healthcare team about the role of OTs within a brief duration (Roberts & Shamus, 2015) v Examining the perceptions towards OTs from health care professionals gives insight into understanding where occupational therapy stands within the health care community (Bonsall et al., 2016) v Although OTs are generally well regarded within the health care community, health care professionals may not fully understand the specific interventions and services that OTs can provide. This demonstrates the need for additional education regarding interventions and services that OTs provide as well as domains of concern in occupational therapy (Bonsall et al., 2016)

RESULTS v Four qualitative themes and five sub-themes emerged during thematic analysis: v Initial Education and Exposure v The participants described their initial education and exposure of occupational therapy to be informal education and personal or secondary experience v "...during my third and fourth year of medical school... the supervising physicians that I would work with would talk occasionally about referring people to occupational therapy." v Influence Perception of occupational therapy v The participants' education and exposure of occupational therapy influenced their perception of occupational therapy scope of practice v "...not only the physical, but maybe some part of psychological support committed means, in order to help the patient really adapt to their new condition" v Perception vs. Occupational Therapy Practice Framework v The participant's perception of occupational therapy scope of practice were found to be accurate or inaccurate with the Occupational Therapy Practice Framework v Accurate with Occupational Therapy Practice Framework v "Anybody in any demographic could potentially be treated by an occupational therapist. I think it goes from essentially newborn to the day before they're dying" v Inaccurate with Occupational Therapy Practice Framework v Parts of the physician's perceptions of occupational therapy scope of practice were found to be inaccurate with the Occupational Therapy Practice Framework, and all participants discussed physical therapy when describing occupational therapy v Missing Components v Participants' perceptions of occupational therapy scope of practice included inaccuracies with the Occupational Therapy Practice Framework v ”…urinary incontinence, pelvic floor prolapse, colon incontinence, pain with intercourse... I don't see occupational therapy sitting into sexual disfunction..." v Physical therapy greater than occupational therapy v All participants stated greater knowledge of physical therapy v "...I think people probably understand what physical therapy does better..." v "I can't imagine it's that much different from physical therapy..” v Physicians' Recommendations to Improve Awareness of occupational therapy v All participants discussed recommendations to improve occupational therapy education, gaps in care, and advocacy as part of the interdisciplinary team
v Education on Scope of Practice v Participants had informal education of occupational therapy or participants had secondhand exposure through family members v "Nothing formal dedicated as far as here's the role of an occupational therapist…." v Gaps in Care v Participants identified areas in care occupational therapy could improve v "If people knew that they could go directly to you… not that differently from them choosing to go directly to chiropractors when their backs hurt…." v Collaboration/Communication v All participants discussed collaboration and communication as crucial components v "They’re part of a larger care team, so I can't fully do my work without having the input of occupational therapists..."
Figure 5. Results and Implications
DISCUSSION v Consistent with other studies, participants acknowledged a lack of education or knowledge of occupational therapy prior to becoming a physician (Aguilar et al., 2013) v Majority of the participants expressed positive perceptions of OTs and believed OTs are an essential part of the interdisciplinary team v Participants described wanting and valuing open communication with OTs v Participant recommendations to improve awareness of occupational therapy’s scope of practice to physicians included communicating and establishing relationships with physicians, educate physicians about the role of occupational therapy and services available, and identify and address local occupational therapy gaps in care v Limitations of this study included a small sample size of six participants, small geographical area, and the diversity of participant specialties
CONCLUSION
v There is a need to improve physician awareness of occupational therapy scope of practice. Opportunities to improve awareness includes OTs providing education, communicating and collaborating with physicians, and identifying and addressing gaps in local occupational therapy services. This study has shown a need for further research to explore the most effective education method to improve physician awareness of occupational therapy.

Title: Perceptions of Physician’s Towards Occupational Therapy Abstract: The study focuses on identifying gaps of physician’s perceptions regarding the scope of occupational therapy. Understanding physician perceptions will encourage effective collaboration between various professions to improve quality of care for clients and the impact to referral rates. Learning physician perceptions will help encourage occupational therapists (OTs) to advocate for clients and for the profession. To answer this question, we interviewed six physicians working at the University of Pittsburgh Medical Center (UPMC) using semi-structured interviews. Our results showed a correlation between communication and positive occupational therapy perceptions as well as the need for further coverage of the scope of practice during continued education. Implications of this study showed a need for improving awareness of occupational therapy through education regarding the scope of practice, closing gaps in care, and increasing collaboration and communication between disciplines. This study has shown a need for further research regarding education of occupational therapy.

PT Pro Bono Enhanced by OT and Restructured to Meet Community Needs Background
Gannon University DPT students developed a relationship with Chosen Inc. in Erie, PA: a non-profit organization that refurbishes and donates medical supplies and equipment to individuals in need in the Erie community and around the world. PT students worked with Chosen Inc. on many projects throughout the COVID-19 pandemic, and the occupational therapy department from Gannon began contributing their expertise to the organization as well. In July 2021, a group of DPT students and professors traveled to Valladolid, Mexico to distribute medical equipment and run a pro bono clinic to provide physical therapy services to members of the community. This service trip inspired students and faculty to develop a pro bono clinic at the Chosen Inc. headquarters in Erie to provide skilled therapy services and wellness resources for the Erie community. The newly established clinic will serve as an extension of the existing Gannon University pro bono therapy clinics, the KnightAbility Clinic and the Little Knights Clinic.
Project Design and Execution
Student therapists worked with Chosen Inc. to streamline the intake of donated equipment by assessing the safety of incoming equipment and preparing them for distribution locally and globally. They also began the legal (including policies/procedures manual) and logistical development of the new pro bono clinic entitled the Gannon Wellness Clinic @ C.M.P. Outreach Pavilion. Students, faculty, and Chosen staff worked closely together to assess the needs of the community and develop a plan to build the clinic from the ground up.
Proposed Services
Upon opening, the Gannon Wellness Clinic @ C.M.P. Outreach Pavilion will provide pro bono physical therapy services, on-site equipment fitting and instruction, and wellness educational sessions. Gannon PT and OT students under the supervision of faculty will utilize their clinical skills and expertise to recommend appropriate assistive devices to improve quality of life, as well as provide education about topics such as reducing fall risk, the importance of mobility, and how to care for your loved ones.
Interprofessional Education
Development of this clinic led to close interprofessional cooperation between the PT, OT, and engineering departments of Gannon University. This multidisciplinary effort expands the reach of Chosen Inc and Gannon University and has led to the development of clinical skills and interprofessional cooperation, while emphasizing core values of skilled therapy. This partnership promotes invaluable hands-on experience with real world patients and other skilled therapy providers.
Conclusions and Next Steps
The Gannon Wellness Clinic @ C.M.P. Outreach is expected to open this spring at the Chosen headquarters on W 26th St. in Erie. Educational sessions and on-site equipment fittings are already in action with continued efforts to raise awareness of the services Chosen offers in the surrounding communities. Future aspirations for this clinic are to involve other health profession disciplines from Gannon University in the clinic, host support groups for clients to attend, and continue to utilize the clinic to expand global outreach.

Title: PT Pro Bono Enhanced by OT and Restructured to Meet Community Needs Abstract: In 2020, Gannon University’s PT department established a partnership with Chosen Inc., a local non-profit medical assistance organization that serves the local and global communities. During the COVID-19 pandemic, PT and OT students and faculty completed various projects with Chosen such as assistive device safety assessment, assistive device educational brochure creation, and reorganization of the data collection system. With the clinical expertise that PT and OT students and faculty have to offer, the departments decided to expand their partnership with Chosen Inc. and develop a new joint PT/OT pro bono clinic in Chosen’s headquarters to further serve the local Erie community. Thus, the Gannon Wellness Clinic @ C.M.P. Outreach Pavilion was born. Once the clinic is officially open, Gannon PT and OT volunteers will provide pro bono services such as in-person equipment fitting, equipment education sessions, and physical therapy services for the underinsured and uninsured members of the Erie community.

Question
Quantitative Data Results
Will children with sensory aversion increase oral acceptance of nonpreferred wet, food items after tactile play with wet, non-food items of similar texture?
Implications for OT • Positive outcomes of this study add to the body of knowledge surrounding the use of the SOS approach in children • • Helps to guide further research for individuals who have sensory difficulties during mealtime
Analysis
Overview • Prior to the study, both subjects refused to eat yogurt when offered by the caregiver • Both subjects reached the highest level on the SOS Hierarchy by swallowing the yogurt (step 23/23)
Purpose The goal of this study was to investigate if play in wet, nonfood items will increase a child’s acceptance of foods of similar texture. The aim was to eventually desensitize the child to the novel food texture via teletherapy, so the child would be more likely to eat the food.
Literature Review Tactile Defensiveness and Oral Aversion Food Neophobia Non-organic Failure to Thrive Picky Eaters Sequential Oral Sensory Approach Environment Dyadic Relationships Mealtime Behaviors Telehealth
Subject 1 (S1) • Reached the highest level on the SOS Hierarchy for the yogurt during the first teletherapy session and maintained the highest level throughout all teletherapy sessions over the 6 weeks (step 23/23) • Highest level reached on the SOS Hierarchy for applesauce was Level 18 during the 4th teletherapy session (step 18/23) • S1 had decreased acceptance of applesauce from teletherapy session 4 (step 18/23) to teletherapy session 5 (step 13/23) • Caregiver daily home tracking showed a slight increase on the SOS Hierarchy during Weeks 4 and 5 Subject 2 (S2) • Reached the highest level on the SOS Hierarchy (step 23/23) by the end of the study • S2 steadily increased acceptance of the yogurt across the six weeks • During teletherapy sessions: • Remained at the same Hierarchy level up to teletherapy session 3 (step 13/23) • SOS Hierarchy levels fluctuated across teletherapy sessions 3, 4, and 5 • Increased acceptance during teletherapy session 6 where they reached the highest level on the SOS Hierarchy (step 23/23)

Methodology
Qualitative Data Results Subjects Subject 1
Population The population consisted of two, six-year-old subjects experiencing sensory aversions to food textures or having difficulty eating wet foods. Both subjects had a diagnosis of autism spectrum disorder (ASD). The caregiver chose yogurt as the nonpreferred wet food item for both subjects. Measures A modified, 23-step version of the Sequential Oral Sensory (SOS) Hierarchy was used to collect quantitative data during teletherapy sessions and daily caregiver tracking. The qualitative data was obtained through observation during teletherapy sessions and pre- and post-questionnaire information provided by the caregiver.
Subject 2
Methods This research study was a mixed methods study with a convergent design. The teletherapy intervention involved 15 minutes of play in a wet, non-food item, 15 minutes of working toward eating a non-preferred wet food, and then 15 minutes clean-up with playtime reward and caregiver education. Guided by the Model of Human Occupation (MOHO) and Sensory Integration (SI) theory.
Negative Behaviors Observed Week 1 • Requiring physical cues to stay seated at tabletop • Initially required min cueing to stay on task • Licking and eating yogurt off hands • Sensory breaks stood as distractions Week 3 • Disinterest in gritty texture
Week 1 • Hypersensitivity to wet textures • Escape behaviors during play portion to desensitize themselves • Initially required mod-max cueing for both tactile play and SOS Hierarchy portions • Inattentive to modeling and cueing from co-investigators Week 2 • Negative responses to aversive textures • “Ewww”
Interactions During Intervention Weeks 1-6 • Caregiver encouragement • “Keep going, you have more paint there” • Interactions between subjects • “High Tens” • Caregiver education regarding adaptive feeding utensils
Weeks 1-6 • Modeling and demonstration • Words of encouragement • “Watch Mommy” • Verbal and physical cues • Interactions between subjects • “High Tens”
Positive Behaviors Attained Week 1 • Independently played in paint and yogurt with hands • Consistent engagement with min to no cueing • Ate a full 4-oz cup of yogurt and this continued daily Week 2 • Consistent use of spoon Week 4 • Progression to additional aversive wet, food • Applesauce Week 2 • Positive responses beginning • “Yayyy”, giggling, smiling Week 3 • Increased time interacting in aversive texture • 5 minutes Week 4 • Increased compliance during tactile play • Increased visual attention to teletherapy screen • Progressed to min-mod cueing for both tactile play and SOS Hierarchy portions
• Therapy context of Zoom© was a barrier • Investigators were required to communicate with the subjects and their caregiver through Zoom© • Investigators were not present to provide hands on and direct input due to teletherapy environment • Only coaching as well as visual and verbal cues were used • Caregiver bias • The caregiver was encouraged to provide correct and accurate data, but bias potentially could have occurred • Environmental Distractions • television, a swing, favorite bathroom environment etc. • Small sample size
Further Research Further research would be beneficial to gain sufficient evidence of the widespread use and effectiveness of the SOS Hierarchy across various pediatric contexts and professions. Research studying individualized teletherapy sessions could provide more direct treatment to help increase the validity of the SOS Hierarchy and intervention results.

Title: The Impact of Tactile Play on the Oral Acceptance of Wet Food Items via Teletherapy Abstract: This mixed methods, research study investigated the impact of tactile play on the oral acceptance of wet food(s) in children with a diagnosis of autism. This six-week sensory-play-based feeding study was conducted via teletherapy. The data was collected using The Sequential Oral Sensory (SOS) Hierarchy, a pre-post questionnaire, and clinical observations. Both subjects reached the highest SOS Hierarchy level and displayed an increase in oral acceptance of wet, non-preferred foods. They exhibited improvements in behaviors toward the non-preferred foods during teletherapy, after 15 minutes of play in an aversive wet, non-food substance. Results also showed an increase in utensil use and positive mealtime behaviors. Further research would be beneficial to build evidence regarding the effectiveness of the SOS approach across pediatric contexts. This study, completed via teletherapy, supports the effectiveness of playing in wet, non-food items and its relation to oral acceptance of wet, non-preferred foods in children.

ACL Reconstruction with a Hamstring Tendon Graft Case Presentation: Introduction: Anterior Cruciate ligament (ACL) tears are more common in females when compared to males. The tears happen due to poor conditioning, or what sport they are playing like soccer, football, gymnastics, basketball and downhill skiing. Some other factors that could cause a tear would be muscular imbalances, wearing footwear that doesn't properly fit, or poorly maintained sports equipment. Some signs and symptoms of an ACL tear would be a loud "pop" or popping sensation, swelling, severe pain, loss of range of motion, and/or feeling like the knee is going to give out. There are different types of grafts that surgeons use such as patella tendon, quad tendon, hamstring graft, or a graft from a cadaver. References: 1.

Management & Outcome: She had ACL reconstruction on August 3, 2021. The surgeon chose a hamstring graft for this athlete. Athlete reports to PT and started to come into the athletic training room for additional rehabilitation January 20, 2022. Athlete has been in to see the athletic training student twice a week and reports to PT once a week.
Discussion: This case is extremely interesting because of the graft that was chosen for the athlete. The hamstring tendon graft is not always used because females have weak hamstrings to begin with. The surgeon who conducts her protocol is very conservative and won't clear her until she is at eight months. It is also difficult because I have had a hard time getting ahold of a protocol from the PT she sees. I have been working with the athlete based on the athlete's word of mouth of how and when to progress/regress her.
Title: ACL Reconstruction with a Hamstring Tendon Graft Abstract: ACL RECONSTRUCTION WITH A HAMSTRING GRAFT Introduction: Anterior cruciate ligament reconstruction is a result of a torn ACL. This ligament is a strong band of tissue that helps connect the femur to the tibia. This injury is seen most in female athletes because of their larger Q angle. Typical signs and symptoms of a torn ACL is a loud pop or “popping” sensation in the knee, severe pain, rapid swelling, loss of range of motion, and a feeling of instability or “giving way.” Case Presentation: A 15-year-old female high school basketball athlete reported to the athletic training room on July 26, 2021. She reported that she was running and heard her knee pop. There as some guarding doing a Lachman’s test and was unable to extend her leg. Athlete was then referred to an orthopedic at UPMC. Athlete was confirmed to have a torn ACL a few weeks later. Management & Outcome: Athlete had surgery September 3, 2021 with a hamstring graft. The athlete should be cleared after 8 months of rehabilitation. The athlete is currently at month 6 and is progressing significantly. However, athlete is still feeling deep knee pain and is currently being assessed for further issues. Discussion: The case itself is significant because of the graft that was being used. Females are already prone to hamstring weakness, so the fact that she has a hamstring graft makes the rehab even more significant. This case is also significant because her surgeon is more conservative and prolongs her rehab two to three more months compared to another local surgeon who clears athletes at 6 months.

ACL Reconstruction with a Quadricep Tendon Graft
Introduction- ACL tears are a pretty common injury in athletics.An estimated 30 to 78 of 100,000 people get an ACL rupture. About 61% to 89% of athletes who get a reconstruction return to activity.1 The usual result is weakness and atrophy of the quadricep and hamstring as well as a lack of mobility for an amount of time during recovery. The calf can also have tightness and low muscular endurance due to the length of inactivity that may be required. Quadricep tendon grafts for an ACL reconstruction will require an ACL rehabilitation protocol that focuses mainly on that quadricep muscle group due to the weakening after the graft has been harvested.2
By: Mohammad Al-Fatlawi
alfatla001@gannon.edu
Management and Outcome- ACL reconstruction by taking a quadricep tendon graft and placing it where the ACL should be was done. A quad tendon graft is typically less painful at the harvesting site when compared to a hamstring graft or a bone-patellar-bone graft.3 She has made some good progress so far in her rehab. Range of motion and strengthening have been the main focuses, as well as getting more muscle mass in her affected leg due to the amount of quadricep and hamstring atrophy that she had. IASTM has been used to help increase blood flow and stretch her muscle structures as well as help with scarring. She does a series of dynamic stretches which includes her hip,thigh, and knees. Following that, strengthening exercises are done to help promote hypertrophy and get her thigh girth measurements equal bilaterally. Her current management stage is right between the strengthening aspect of her rehabilitation process and easing into her running progressions hopefully relatively soon.
Case Presentation- 16 year old female high school basketball player who tore her ACL in the beginning of the season and had her ACL reconstructed surgically. She had a quad tendon graft and has had a noticeable amount of atrophy in her quadricep and hamstring tendons. She also has a lack of feeling on the lateral aspect of her lower leg. Patient has not began a running progression yet and is still in the strengthening and ROM phase of her rehab. The athlete has had no previous history of knee injuries.

Discussion- While the athlete continues rehab, progressions will be noted for strength and range of motion. The individual is a duel athlete who also competes in softball. The potential for her to play this season is low, but progressions towards return to play will be done based off of her physical therapist’s and team physicians protocols. While this is still an active case study, seeing the running progression and return to play protocol will be viewed next. As previously stated, the protocols are based off of her physical therapist and the team physician, so no progressions have been made until they see fit.

Advanced Rehabilitation Techniques for Acromioclavicular Joint Sprain in a Major Junior Hockey Player Introduction Acromioclavicular (AC) Joint sprains are common injuries for many athletes, specifically hockey players.1,2 The AC joint is made up of the clavicle and the scapula meeting at top of the shoulder. Mechanism of injury for an AC joint sprain in hockey is typically caused by direct contact of the shoulder with another player or the boards.1 Typical signs and symptoms are pain at the joint, weakness in strength when compared bilaterally, or a visible deformity. These types of sprains are graded from I-VI depending on the evaluative findings and imaging.
Case Presentation A 20-year-old male major junior hockey player reported symptoms from a hit into the boards indicative of a grade II AC joint sprain. Image findings were consistent with a grade II AC joint sprain according to Rockwood Classification. Athlete was able to return to play, full contact two weeks after injury. The athlete was given a custom orthoplast mold with a foam doughnut pad anchored with leukotape to protect the area during contact play. Management & Outcomes Conservative rehabilitation and treatment was done daily with the athlete. Rehabilitation was conducted in three phases; range of motion/isometric, concentric, and sport specific. Treatment included the use of modalities such as electrical stimulation, cryo-compression, and joint mobilizations. Athlete was able to begin with active range of motion exercises which Figure 1 allowed for a quicker progression into phase II.
Isabelle Vieira ATS vieira004@gannon.edu
Discussion Typical Type II AC Joint sprains take 8-12 weeks to rehabilitate before heavy lifting and contact sports can be resumed.4 This case demonstrates that integration of early range of motion and gradual reintroduction to lifting techniques aids in quicker return to contact play and heavy lifting.

Aging in Place: Views on Intimacy Adasiah Carlson, Alexandria Hotz, Mackenzie Fitzgerald, Elizabeth Maurer, and Hannah Spiess
Abstract A phenomenological qualitative study was conducted to understand the perception of intimacy of people over 40 years old. Researchers conducted an 11-question survey via phone to seven participants. The data was analyzed through thematic analysis. The results revealed that most of the participants did not believe that aging affected their view on intimacy. However, themes discovered in the research identified varying lifestyle influences and selfconcepts as factors that affected their perception of intimacy within their life span. Additional evidence-based research is needed to further the discussion of understanding intimacy and aging.
Thematic Results Influences
Perceptions Intimacy
Occupational Therapy and Intimacy Occupational therapists’ role in activities of daily living include tasks such as toileting, dressing, and bathing which are all acts of intimate care that present further opportunities for occupational therapists to address additional intimate topics. In regard to intimacy, occupational therapy practitioners can address goals and desires of the patient. Lichtenberg (2014) stated the following: Holistic care must include the occupational therapy practitioners’ inclusion of sexual needs and concerns of older adults, and in fact, due to their training in holistic, and person-centered approaches the practitioner may often be in the best position to broach sexuality with older patients in long term care facilities. (p. 50) Frequently, older individuals are hesitant about discussing intimacy when opportunities arise for them to express themselves because of physical, emotional, cognitive, or psychological barriers (McGrath & Lynch, 2013). Therapists should educate individuals about how sexual activity increases life satisfaction, reduces loneliness and depression, and prolongs life (Lichtenberg, 2014).
Romantic “It would be feeling of trust, emotional, physical closeness. Probably designed for connection with another soul.” Emotional “Being close to someone whether it be a husband, child, or friend” Physical “We age our bodies change too but that doesn't mean we can't have intimacy in different forms like cuddling.” “He’ll pat my butt… I’ll give him a big hug or kiss for no reason”
Lifestyle Religion “My husband and I both practice religion, we're Christians and totally have a part of our life. You know, he treats me with respect like the Bible says you should. And I do the same for him. I think it impacts our life a lot.” Divorce “The intimacy was going through a very difficult divorce. You know, not having the 100% trust in a partner that you really need to have, you know, for that intimacy, and that impacted me for a number of years until I finally was over.” Illness “Oh, big time because of the constant chemo and poor man went through…Because I love him. That's not why I'm married to have sex constantly, you know I didn't quite understand that first he says you know if I understand. But we're still intimately connected. He still makes me happy.” Work Status “just a 30-year-old... young and married and starting a family and that kind of stuff. You know you get so caught up in just the daily business of dealing with life at that point of time there is no intimacy, you know, right, you're dealing with crying babies, you're dealing with work you're dealing with a husband that works.”
Self-Concept
Aging
Methodology Population The target population was recruited within the state of Pennsylvania and included seven people who are the age of 40 and older currently living in Pennsylvania. Recruitment flyers were distributed through social media platforms and within community establishments. The inclusion criteria consisted of people 40 and older, currently living in the state of Pennsylvania, who had been involved in or were currently involved in an intimate relationship. A person would be excluded if one did not meet the inclusion criteria. The participants selected consisted of six females and one male through purposeful, maximum variation sampling. Research Design The research study is qualitative with a phenomenological design because the data will reflect an individual's lived experiences regarding intimacy and aging (Creswell, & Poth, 2018). The research design did not include blinding of participants or researchers because it was a semi-structured interview conducted on the telephone. The research study was guided by the Ex-PLISSIT model, which includes an extended permission component requiring the participants to be aware of the study (McGrath & Lynch, 2013). The data was collected through a one-time telephone call guided by semi-structured interviews lasting 15-20 minutes starting in February of 2021 and continued throughout April 2021. The Otter App was used to record the interview and the information was stored by password protection on one researcher’s phone.
Discussion
Healthcare Professionals “With the healthcare professional I have no problem. I don't have any hang ups, I don't. I'm not shy about it. I have no problem discussing any issues or anything like that, I am pretty open.”
Process of Aging "Whatever you are, whatever age, it's what you want in life or how you have a marriage, it's what you make of it." Emotional vs Physical Connection “Yes, as I get older. I feel there's more of an emotional connection and less physical connection.” “I guess it would be important to me because intimacy would be a mingling of your souls and sharing of heart.” “I think it's important I think you need to show the person you're with that you love them not just there to have sex.”
“Very comfortable due to experience… because of cancer that could have either tore us apart or pulled us together, and the first month he was in the hospital I wouldn’t believe… he was in so much pain it was horrible.” Self Esteem “... but like I said, because of my self-esteem and self-image I didn't like it when I was married to my first husband. I didn't want him touching me. I felt fat and ugly, because that's the way he made me feel.” “You can’t be comfortable with intimacy until you really know who you are, what your fears are, your dreams, your hopes, your desires”“internal portion of intimacy that needs to be reflected on yourself before you can be intimate with another person.”
In this qualitative study, the purpose was to understand how adults over the age of 40 perceive intimacy. The results indicated themes including intimacy, aging, lifestyle influences, and self-concept. Intimacy can be perceived in a multitude of ways; therefore, individuals may consider themselves intimate with a variety of people in their lives such as family, friends, and/or spouses. More than half of the participants in the study stated that their perception of intimacy did not change over time as they aged. However, lifestyle influences such as marriage, divorce, illness, religion, and work status impacted how participants view intimacy. Also, an individual’s self-esteem impacts how one engages in intimate relationships and how comfortable one is in discussing intimacy with healthcare providers. Intimacy is a fulfilling part of life, and a person can never be too old to engage in intimate relationships and sexual activity. Future research should be conducted to investigate the distinct role of occupational therapy in addressing intimacy among the aging population.
Implications This research is significant because it demonstrated how the aging process can affect intimacy. The literature and results highlighted that one’ perception of intimacy is individualized and should be approached holistically. Occupational therapists can address all parts of the multidimensional topic of intimacy including sexual activity and intimate partner relationships. Within occupational therapy’s scope of practice sexual activity is recognized as “sexual expression and experiences with oneself or others” according to the OTPF-4 (AOTA, 2020). Additionally, intimate partner relationships involve “activities to initiate and maintain a close relationship” (AOTA, 2020). In regard to the various aspects there are to intimacy, occupational therapy has a unique role in addressing intimacy with the aging population to increase one’s quality of life and occupational engagement.

Title: Biofeedback Smartwatch Application for Migraine Prevalence Abstract: This capstone researched biofeedback as an intervention to alert patients to migraine onset during occupations. Biofeedback has been researched for its effect on migraine prevalence but has not been researched in respect to smartwatch technology or integrated with occupation-based activities. Four participants described the frequency of migraines experienced. They recorded heart rate at baseline and at migraine onset wearing a smartwatch. They completed post-test by recording heart rate, activity performed at onset, and migraine frequency. Results indicated an inconsistent relationship between heart rate and migraine onset with use of smartwatch applications. Further research is indicated to examine this relationship with more consistent data.

Correlation Analysis between Division 2 Men's Basketball Transfer Players and their Success Kevin Paton
Jinhee Yoo (Advisor)
Introduction
With the implementation of the new transfer portal for college athletes, and the new name, image, and likeness (NIL) policy that the NCAA has adopted have given the players more decision-making abilities than ever. The NCAA college basketball tournament generates over one billion dollars a year (Parker, 2021). The NBA has a minimum salary of $925,258 for rookies and this number increases every year additionally in the league. These figures mean athletes and schools alike need to make the best decisions possible for success. The goal of this study is to examine the statistical success of athletes after they change division. There are over 300 schools that compete at the Division two level. Each of these schools have rosters of 12-15 athletes. This leaves thousands of potential participants. The NCAA is also exceptionally good at keeping records of where athletes play, and what stats they record.
measured were games, starts, minutes, as well as points, rebounds, assists, blocks, and steals per game. Once the 28 players for each category were selected those stats for years one and two were collected and entered a Microsoft Excel© file. This data was then organized and Analyzed. Averages were generated using the player stats for each year and for each category. The averages were then charted for year one (Figure 3) and for year two (Figure 4). Then the Data and charts were analyzed Figure 1: Conference Point Differential vs Win%
Research Question
Is there a correlation between interdivision transfers and success? The focus of this study was to examine the statistical difference between players who transferred from division one school to division two school, players who transferred from division two schools to division one schools, as well as a control group of players that remained at their school. We did not want any conference bias, or any other major statistical effects based on the team play factor into this study. The first thing to do was to conduct a cross analysis of team success and see if the same factors that aligned with team success worked across all conferences (Figure 1). It was determined that there was a linear correlation between point differential and win percentage when sorted by individual schools (Figure 2 ) The data was collected from the NCAA official webpage. The data was analyzed in Tableau. This is all to help colleges and universities as well as athletes and their families make the best decisions on where they will play to best help all their respective careers. There were 28 athletes that were selected for each category bringing the total participants to 84. There are many different athletic conferences within D2 basketball. The selection process of the athletes was based off conference. Once there was an understanding that there was no statistical difference between the conferences and teams, we can then begin to collect athletes' stats for their seasons. The athletes were selected using a series of random number generators. Once a player was selected it was determined if they fit the criteria for the study. They needed to play in back-to-back seasons. They either needed to play D2 then D1, D1 then D2, or remained at their school. . Success will be defined as an increase in on court statistical output. The statistical categories
Figure 2: Team Point Differential vs Win%
Findings
It can be seen in the charts below that there was a measurable increase in all measurable categories for the players who transferred from division one to division 2. The players who remained at their schools saw smaller but still positive increases in their on the court production. There was a decrease in production from players that transferred from division two to division one schools. This can be attributed to the higher level of completion and competitiveness at the division one levels. Players that transferred from division one schools into division two schools saw an average increase of 11 more starts per year, with an increase of 5.4 points per game, 1.7 rebounds and 1.2 assists per game. That represents a 256%, 213%, 110% and 250% increase across those stats from their previous year. On the other side of the study the players that transferred from division two to division one saw an average decrease of 5.4 starts, 4.4 points, 1.2 rebounds, and 0.7 assists per game. These number decreases would not be considered an increase of success. The average stats from years one (Figure 3) and two (Figure 4) are in the charts below along with the percentage change from year to year (Figure 5). Figure 3:Player Stats1in First Season Year

Data Analysis
Once the data was collected and put into the Microsoft Excel© file the next step was to generate averages for the eight stats that were recorded. Players were evaluated based on their Games Played (GP), Games Started (GS), Minutes Played (Min), Points Per Game (PPG), Rebounds Per Game (RPG), Assists Per Game (APG), Blocks er Game (BPG), and Steals Per Game (SPG). These are generally used as measures of success in basketball as it measures their impact on the court for their team. We also wanted to make sure they Games played, started and minutes per game were also recorded as this is what gives players more opportunities to succeed.

Discussion
When looking at the fundamental questions of this study is can be seen with the dramatic differences seen in the chart above that there is a major difference between statistical success between athletes that transfer between divisions. Athletes that are looking to increase their statistical production as a result of transferring should look at moving between divisions, as there is a clear correlation between decreasing in division and statistical output on the court. Success can be interoperated as a measurable increase in statistical output on the court. This can be seen by the athletes that move into the D2 space from D1. Overall based on the results of this study it can be said that if players are looking to change schools and have a dramatic increase in statistical output moving to a lower division can be a great boost in that direction.

There are always limitations to any study, this one is no different. When looking at the participants there was a specific set of criteria that they had to meet. If they transferred within the same division then they did not qualify as they would have needed to wait a year because of NCAA rules. This has changed with the new transfer portal. It will be interesting to see how that effects the mobility of athletes. There was also a limited sample size of only 84 participants. Ideally this study could look at players from all levels and examine any potential shifts in statistical success. Future studies could examine high majors, mid majors and low major transfers as well as a mix of divisions two and even division three athletes. There could also be future studies examining the level of perceived statistical success by NBA scouts to determine if lowering division and increasing their stats can stull correlate to a successful career at the next level.

Cost Effective Alter native Flight Simulator Training Device (FSTD) Kaden Conley1, Dr. Xaioxu Ji1, Dr. Davide Piovesan1 Biomedical Engineering1
Background Flight simulator training devices (FSTDs) have been used to provide a safe and controlled training environment for pilots. FSTDS have been used to prevent Loss of Control (LOC) accidents from occurring [1]. FSTDs are easily accessible and do not require flight plans, good weather conditions, and have a reduced economic impact (cost of flight time, fuel, etc.)[2]. Recently, virtual reality (VR) simulators have been used to engage youths in STEM [3]. The use of VR for FSTDs is to learn about aircraft safety. Our FSTD looks to combine VR and a 6 DOF platform. This will allow for the user to have a more visually and physically realistic simulator. This will also reduce the cost of the simulator and in turn reduce the cost of training. This technology can be further applied to other simulators in the future.
Methodology
Results and Discussion
Equipment Used • 6 DOF Stewart Platform •Visual studio •C++ •Microsoft Flight Simulator •Arduino & accelerometer Operating Modes
Our FSTD has two different operating modes. These being direct coordinate input and the flight simulator. Both operating modes utilize C++ code for operation. The direct coordinate input allows for the user to input a movement path for the platform to follow. The code reads a CSV file including the positions and movement time. The flight simulator has three different versions that can be used. The first mode is just the raw position data, the second adds velocity and acceleration, and the third makes the velocity and acceleration more realistic.
Full Flight Simulator
Safety To ensure the platform was safe to operate the full range of movement for the platform was found. (x-: 440 mm; y-: 440 mm; z-: 400 mm) and minimum (x-: -440 mm; y-: -440 mm; z-: 0 mm). This allowed the platform to not exceed its limits. The code based stop implemented checks every move the platform makes to ensure it can make it. And lastly two physical emergency stop buttons were added. Cost
The 6 DOF platform and the computer
First person view from Microsoft Flight Simulator
The FSTD that was developed has a lower price range than those on the market. The lower end of cost is a reconfigurable training device costing around $50,000 to $120,000. On the high end simulators can cost around $5 to $15 million [4]. Compared to the cost of our platform being from $16,000 to $20,000.
Impact The combination of VR and a 6 DOF platform for use in an FSTD allows for a realistic and personalized flight training environment. It is able to provide and safe and controlled training environment for new pilots while being affordable. This technology can be further used for other vehicle simulators or for sports rehabilitation.

Title: Cost Effective Alternative Flight Training Simulator (FSTD) Abstract: The 6 DOF Stewart platform is successfully integrated with the Microsoft Flight Simulator software for the purpose of achieving a realistic flight experience. A safe and controlled environment was provided in this study to eliminate the accident rates for flight trainees. Moreover, it could move properly via following a randomly created code within its safety movement range. Our study will provide a new opportunity for the organizations in the area of training to implement this advanced technology into various types of simulators. This fusion technology has greatly reduced the cost and made the training easily available. This advanced technology could be widely applied in various types of simulators, such as automobile, bicycle, rowing, or sports rehabilitation.

Does direct caregiver education on modifications decrease falls in the ALF setting? Post Professional Doctorate Program
Teri S. Krassen, MHA OTR/L Krassen001@gannon.edu Faculty advisor: Dr. Aime Rizzuto
Abstract Rationale • Falls are an enormous problem in the United States • 1 in 4 adults over age 65 will fall each year, translating to 36 million falls • 37% of these falls require medical attention
Falls are a major problem for all older adults including those that reside in assisted living facilities. This study posed the question of whether staff education in environmental and cuing modifications will decrease the incidence of falls in one assisted living facility. The study also examined whether an occupational therapy led education program would lead to increased knowledge regarding the risks of falls and the appropriate measures all staff can take to decrease falls. The methods used were a survey of pre and post education knowledge, an educational program led by an OT, and a review of the incidence of falls pre and post the education.

Sample Education Slide
The fall education did not result in a decrease in falls. Prior to the education there were 19 falls out of 27 residents and the month post education there were 24 falls out of 32 residents.
The study did support the location of falls as 42 out of 43 falls occurred in the bedroom or bathroom. The time of falls was spread throughout the day, so this did not support previous studies that maintained falls were more likely in morning and evening .
Title: Does Direct Caregiver Education on Modifications Decrease Falls in the ALF Setting? Abstract: Falls are a problem for older adults, including those in assisted living facilities. This study assessed whether staff education regarding modifications would decrease the incidence of falls in this setting. The study included a survey, educational program, and review of the fall incidence. Results indicated that education did lead to increased knowledge of fall prevention however, the number of falls showed no change. Results support OT as a provider of education in fall prevention for caregivers to increase knowledge.

Title: Eight Senses Goal Setting Assistant: A Pilot Study Abstract: In the client-centered philosophy, the occupational therapy process incorporates parents’ input regarding interventions for their child. This capstone project examined the efficacy of a web-based tool, Eight Senses Goal-Setting Assistant (ESGSA), to capture parents’ sensory concerns of their child. The study used mixed methods to analyze ESGSA data and determine parents’ perception of the tool in goal setting process. Qualitative findings revealed that ESGSA could capture parents’ concerns in sensorimotor, emotional, and attention areas and their hopes for their child’s intervention. Parents reported more social challenges during their interviews than the ESGSA tool’s identified problems. Quantitative results from a 7-point rating scale support the parent’s perception of using the tool to participate in goal setting.

“I think one of greatest feelings of success comes to me as an occupational therapist when I have truly used occupation-based and occupation-focused activities and seen the joy /fulfillment of the experience with my children... Success to me is to veer away from a deficit focused traditional approach to a health promotion approach and the seeing our kids be really engaged in every moment and make it count.”

Results
Future Endeavors
The occupational therapy field experts who completed a content review of the modules prior to fabrication of the online course had overall positive reviews of the outline. The first reviewer answered all questions as accurate and reported the content outline was “well thought-out and met all ACOTE standards”. The second reviewer agreed that the module would be beneficial for incoming fieldwork students. This reviewer believed some content was not appropriate for incoming fieldwork students reporting “it may be too advanced, and the student(s) may not know the terms and conditions”.
• Integrated into an established course in a graduate occupational therapy program • Add an in-person lab component to increase students’ confidence and allow them to practice the skills they learned • Once established, run more research with the participants being graduate occupational therapy students
Qualitative Data
This study was designed to create an introductory module for graduate occupational therapy students surrounding the kinesiotaping knowledge they may need prior to beginning their fieldwork experiences. More specifically, the study was designed to gain feedback and ensure learning took place throughout the researcher-created module.

Qualitative Data
Background Evidence supports the use of kinesiotaping for various conditions for all ages to improve pain levels, mobility, and overall function. 1,2 Occupational therapists utilize different techniques of kinesiotaping over various lengths of time to improve functional outcomes across the lifespan.1,2
The pre and posttest responses from all fifteen participants were gathered and deidentified. A significance level was set a 0.05 and a paired t-test was run to gather results. The data analysis produced statistically significant results.
Evidence also supports the use of an enriched virtual model of blended learning for asynchronous learning. The backbone of this learning module supports the use of student learning online, promoting the accountability and responsibility of students.3

Significance to Occupational Therapy Kinesiotape allows occupational therapists to facilitate or inhibit muscle groups, decrease edema, complete mechanical corrections and perform various other techniques in order to increase their client’s mobility, decrease pain, and overall increase their ability to participate in meaningful occupations. Kinesiotaping can decrease the need for preparatory activities in therapy or daily life to allow the therapist and client to focus on more meaningful activities during the therapy session.

Title: No Longer Emerging: Occupational Therapists’ Perception of an Aleatory Shift to Telehealth Abstract: Health care policies, improved communication in health care industries, and advanced technological applications have influenced the occupational therapy profession’s service delivery in the past decade. This online survey explored 22 occupational therapy practitioners’ perceptions of their occupational performance during their transition to telehealth in school-based practice. A high percentage of respondents rated that they were “very effective” to “mostly effective” at maintaining their performance patterns (68%) and performance skills (82%) during the transition to telehealth. Regarding occupational adaptation, 76% of respondents rated that they “strongly agree” to “agree” that they met role expectations, adapted to the virtual environment, and had competent problem-solving skills with the transition to telehealth. Responses involving impaired ability to provide high-quality OT interventions, 55% responded “no,” and 45% of the participants responded “yes.” This information may be beneficial to OTs and education stakeholders as telehealth may remain a viable option for OT service delivery.

Occupational Engagement and Well-Being During COVID-19
METHODOLOGY
ABSTRACT
RESEARCH QUESTIONS • What are the relationships among occupational engagement, mental health, and well-being during the COVID-19 pandemic? • What are the differences in occupational engagement and sense of well-being between people with and without mental health challenges?
The COVID-19 pandemic was a time of stress for many, but little is known about how people’s activities affected their well-being. This study investigated relationships among occupational engagement, mental health, and well-being in individuals with and without mental health conditions. Participants (N = 105) from 15 states completed an online survey that included Engagement with Meaningful Activities Survey (EMAS), Depression, Anxiety, Stress Scale (DASS-21), Meaning in Life Questionnaire (MLQ), and Satisfaction with Life Scale (SWLS-3). Significant correlations were found between occupational engagement and mental health (rs = -.471, p < .001), meaning in life (rs = .297, p = .002), and life satisfaction (rs=.587, p < .001). People with mental health conditions reported higher anxiety (U = -.2052, p = .040); no significant differences were found in occupational engagement or well-being. Findings suggest that engagement in meaningful activities was related to mental health and well-being during COVID19. Implications for practice are discussed.
DATA COLLECTION Data were gathered using an online survey that incorporates several instruments: EMAS, MLQ, SWLS-3, and DASS-21. DATA ANALYSIS • Spearman Correlation: Explored relationships among occupational participation (EMAS), well-being (MLQ and SWL-3), and psychological distress (DASS-21 and subscales of depression, anxiety, and stress). • Mann-Whitney U test: Analyzed whether there were significant differences between people who were being treated for mental illnesses and those who were not. The Mann-Whitney U test was chosen because of the unequal sample size between the 2 groups. PARTICIPANTS

DISCUSSION
• The results indicate that occupational engagement is impactful to the well-being of people with and without mental health conditions. • As people get older, overall mental-health tends to improve • Mental health is strongly related to satisfaction in life, occupational engagement, age and if they are receiving treatment for a diagnosed mental health condition • Satisfaction with life was strongly correlated to their occupational engagement and overall mental health. • Engagement in activities is strongly correlated to their overall mental health, meaning in life, satisfaction with life, and age. • Meaning in life has a low correlation to their mental health but is significantly correlated to their occupational engagement. • Individuals who identified they were receiving treatment for a diagnosed mental health condition had significant differences in their overall mental health and anxiety in comparison to those who were not. • No differences were found between those who were not receiving treatment in regard to their levels of depression, stress, occupational engagement, meaning in life and satisfaction with life • Increasing occupational engagement can be a useful intervention to improve sense of well-being with clients with mental health issues
FUTURE IMPLICATIONS
Age range was significant negatively correlated with DASS21 scores (rs= -.558, p < .001), suggesting that older people had less psychological distress.
INTRODUCTION
Occupational engagement is a continuum of observable participation in occupations that can be influenced by internal factors such as volition and motivation, and external factors of environment, transportation, and opportunity (Morris et al., 2017). • People participate in occupations that are meaningful to them and experience a sense of well-being when engaged in these activities (Ikiugu et al., 2019). • The social isolation experienced during the COVID-19 pandemic brought many mental health challenges due to the loneliness individuals felt (Lesser & Nienhuis, 2020). • The purpose of the research is to better understand the relationships among occupational engagement, mental health, and well-being during the COVID-19 global pandemic. • Occupational engagement is significant for people’s mental health and is especially essential for individuals experiencing mental illness (Leufstadius & Eklund, 2014).
29% of participants responded “yes” to receiving treatment for a mental health condition. Being treated for a mental health condition was significantly correlated with DASS-21 total and anxiety scores, but not with other variables.
RESULTS
• When investigating psychological distress using the DASS21, moderate relationships were identified with satisfaction with life (rs = -.562, p < .001), occupational engagement (rs = -.471, p < .001) and age (rs = -.562, p < .001). A weak relationship was identified between psychological distress and those receiving treatment for a diagnosed mental health condition (rs = .205, p = .036). • Moderate relationships were identified between satisfaction with life and occupational engagement (rs = .587, p < .001) and psychological distress (rs = -.562, p < .001). • Occupational engagement was surveyed through the EMAS and showed a moderate relationship with psychological distress (rs = -.471, p < .001) and satisfaction with life (rs = .587, p < .001). There was a weak relationship between age (rs = .269, p = .006) and meaning in life (rs = .297, p = .002). • Meaning in life was surveyed through the MLQ and resulted in a weak correlation to psychological distress (rs = -.191, p = .052) and a weak correlation to occupational engagement (rs = .297, p = .002). • Statistically significant differences were found regarding overall psychological distress (U = 804.500, p = .033) and anxiety (U = 816.500, p = .053) for those who were receiving treatment for a diagnosed mental health condition in comparison to those who were not. No significant differences were found between those who were and were not receiving treatment regarding depression, stress, occupational engagement, meaning in life, and satisfaction with life.
This research is significant because it supports the importance of occupational engagement and its impact on well-being, which emphasizes a need for occupational therapy services. • Further research should be done to explore the longterm relationships between occupational engagement and well-being as the effects of COVID-19 continue to develop. • Relationship between age, occupational engagement, and well-being should be researched further. • Occupational therapy intervention focuses on increasing participation in occupations and advocates for independence of daily living and can provide adaptions and enable people to engage in their desired occupations to maintain their well-being during times of occupational deprivation.

Background As children enter foster care, many receive developmental and mental health services. However, these services are requested based on their caseworker's professional discretion (Child Welfare Information Gateway, n.d.). One way to increase the early detection of child needs would be to ensure that those involved in the child's case have the most up-to-date information recognizing the importance of developmental milestones in young children. Those involved in the child's case can provide preliminary screenings and assessment of milestones early in the child's placement, as developmental delays and needs may have been missed if the child was in a situation of abuse or neglect. Then, a referral to EI services where an interdisciplinary team can provide assessments and appropriate interventions.

Background Since the development of the Individuals with Disabilities Education Act (IDEA), there have been four significant changes, including the amendment to include transition services for students to address further education, work, and independent living (IDEA, 2004).
Assessments/ Screeners
Potential Focus Areas
According to the National Center for Educational Statistics (2019), approximately 67% of graduates in the United States were students with disabilities.
Intervention Ideas
Conceptual Models
Individuals with Disabilities Education Act (IDEA) In Section 300.43 of the Act, transition services are described as activities which improve academic and functional success of students with disabilities to facilitate matriculation from school to post-school activities (U.S. Department of Education, 2017). Person-Environment-Occupation (PEO) Model The model identifies three key components which include the person, the environment, and the occupation (Strong et. al, 1996). All three components are considered to influence one another. These interdependence of these three factors continue throughout a lifespan and various life transitions for all individuals.

Title: OT Transition-Related Services Toolkit Abstract: Special education services, including transition-related services, are developed to ensure that the needs of students with disabilities are met. Individualized Education Plan (IEP) teams, inclusive of parent(s), teachers, and occupational therapists (OTs) develop the IEP that includes transitioned-related goals which aim to outline a guide of how to prepare students for life after graduating high school. This Capstone Project included the development and assessment of a Transition Service Toolkit for OTs to utilize while supporting transition goals. A survey was provided to participating occupational therapists to gain insight regarding the usefulness and suggested improvements for the Toolkit. The Toolkit may help to increase OT participation in transition-related services. Presenter(s): Kevondria Cager Sponsoring Department: Occupational Therapy Doctorate Project Mentor: Janis Leinfuss

Perceived Quality of Family-Centered Care Provided by Occupational Therapists in Ear ly Inter vention
Research Question What is the overall caregiver satisfaction with the family-centered care approach in Occupational Therapy (OT) Early Intervention (EI) programs in the United States?
Background Individuals with Disabilities Education Act, Part C •Established to improve development of infants and toddlers with disabilities (US Government, 1975) •Updated in 1986 (Center for Parent Information & Resources, 2012) Practice Guidelines (Clark et al., 2013) •Evaluation: document strengths and weaknesses of the child •Screen for deficits and plan programs •Intervention •Information from evaluation is integrated with evidence from literature, professional judgment, client values, theory, and practice models •Social- emotional development •Feeding, eating, and swallowing •Cognitive development •Motor development
Framework Family-Centered Framework for Early Intervention (FCFEI), also referred to as the family-centered approach. • Grounded in the Model of Human Occupations • There are increased rates of perceived satisfaction among families in OT EI when using the FCFEI (Schaaf & Mulrooney, 2018)
Grace Hartfiel-Carr, Miranda MacWhirter, Carolyn Schreck, and Marissa Witkowski Hartfiel001@gannon.edu Macwhirt003@gannon.edu Schreck005@gannon.edu Witkowsk008@gannon.edu
Methods Population Family-Centered Care Assessment for Families • Primary caregivers over the age of eighteen with (FCCA-F) Survey (Wells et al., 2015) • Measures the quality of family-centered care that children who received OT EI services in the Unita healthcare professional provides to clients ed States within a year prior to data collection • Twenty-four questions, Likert style survey Inclusion Criteria • Researchers added two demographic questions to • The child must have been actively receiving OT EI the survey services or received a minimum of one session. • The child must currently be under the age of five or have been under the age when receiving services. Exclusion Criteria • Caregivers who are under the age of eighteen • Non-primary caregivers • A child who attended an OT session outside the previous twelve months • A child who received EI services not including OT
Discussion This research determined the overall satisfaction among primary caregivers towards OT EI services is high. This was shown through mean calculations and dichotomous values. Some examples of areas where family-centered care can be improved include: • Helping the child understand medical tests and treatments before they are performed (Q.11) • Asking caregivers if they would like other community members to be involved in decisions about the child’s health care (Q.19) • Asking about family beliefs and practices (Q.20) • Discussing the caregiver's preference for traditional or alternative practices (Q.21) • Providing connections to additional community services (Q.22) • Has a way to connect with families in similar life situations (Q.23) • Gives information to help people outside the family understand the child’s needs (Q.24) The results of this study would help increase family -centered care in OT EI programs. Further research would benefit the literature.
Results Total scores of the ten participants were calculated by adding the twenty-four individual questions. Each question was rated by participants using a 5-point Likert scale: • 1 = almost never or strongly disagree, 2 = rarely or disagree, 3 = neutral or sometimes, 4 = usually or agree, 5 = almost always or strongly agree Satisfaction rates were determined for each question of the FCCA-F using dichotomous variables (1 and 2 on the Likert scale = dissatisfied and 3, 4, and 5 = satisfied). These satisfaction rates are shown with questions, 11, 19, 20, Figure 2 21, 23, and 24 with satisfaction rates less than or equal to 80 percent (figure 1). Overall, there was a high rating of family centered care among caregivers in Pennsylvania, New York, Massachusetts, and New Jersey. Ohio had a lower rate of perceived family-centered care. The mean for each question varied based on the specific area of family-centered care considered (figure 2).
Implications and Further Research The discoveries of this study can help to further improve OT EI services through the continued integration of family-centered care and feedback from families. Strengths and weaknesses can be utilized by organizations to target specific areas of improvement within OT EI programs. This research further encourages obtaining feedback from families to integrate positive changes into OT EI programs. Literature would benefit from: • Research including all fifty states • Further investigation with qualitative research • Well-rounded viewpoint on perceived familycenteredness of OT EI

Title: Perceived Quality of Family-Centered Care Provided by Occupational Therapists in Early Intervention Abstract: The purpose of the research was to measure the perceived quality of family-centered care provided by Occupational Therapists to Early Intervention clients in the United States. This descriptive study using quantitative measures utilized the FamilyCentered Care Assessment for Families (FCCA-F) to gather data from primary caregivers of children in occupational therapy early intervention services across the United States. A modified version of the FCCA-F, a 24 question Likert-style survey, was distributed nationwide through the social media platform Facebook. Ten primary caregivers completed the survey across the North East region. This included residents from Pennsylvania, Ohio, New York, Massachusetts, and New Jersey. The results demonstrate an overall high satisfaction in caregivers of children receiving Early Intervention services.

Purpose for Research The purpose of conducting this research was to gain a better understanding of chronic pain treatments and their effectiveness. This was done to better understand participants openness in utilizing alternative methods as a replacement for opioids.
•
Population •

•
•
18 years or older, experiencing chronic pain for greater than 6 months Sampling size: 10
90% of participants noted sleep and leisure as an area most affected by their pain, while 80% reported exercise and 60% reported walking. The occupations effected by pain could be exacerbated by body mechanics and lack of education on self-regulating strategies or energy conservation techniques. Participants reported the activities of daily living (ADLs) most affected by chronic pain are rest and sleep, self-care, and functional mobility. It was also found that participants reported decreased energy due to chronic pain, which resulted in difficulty completing home management activities and effected social participation. Occupational therapists can increase awareness, provide education, and suggest specific strategies to their clients for alleviating their pain.
Exclusion criteria: clients who had a surgical procedure done resulting in chronic pain.

Opioid Use: In 2017, more than 191 million opioids were prescribed to Americans (Opioid Overdose, 2017). The age group in which the abuse of prescription opioids is most common is young adults ages 18-25 (Chang & Compton, 2016). Risk Factors & Side Effects: Risk factors that are associated with the prolonged use of opioids post-surgery include low income, younger age, specific comorbidities such as diabetes or pulmonary disease, and the use of specific drugs prior to operation including benzodiazepines and selective serotonin reuptake inhibitors. Common side effects of opioid use include dizziness, vomiting, physical dependence, development of a tolerance, and sedation (Moss, 2019). In a study done in Ontario, Canada acute care hospitals, approximately 3% of patients continued to use prescribed opioids for more than 90 days post-surgery (Clarke et at., 2014). Complementary Health Approaches: Studies have shown that complementary approaches are used by approximately 30% to 40% of the general U.S. population (Nahin et al., 2016). Massage: Four randomized controlled trials were examined to see the effectiveness of massage for chronic neck pain. The summary of these trials showed that individuals who participated in massage therapy showed improvements in pain and range of motion over those who did not use massage therapy (Nahin et al., 2016). Yoga: Evidence from six studies, where yoga interventions were designed to emphasize the use of posture and breath for managing pain, showed a reduction of pain in participants (Nahin et al., 2016).

50% of participants cited arthritis as the root cause of their chronic pain. 3/5 of the participants with arthritis preferred alternative methods, finding relief of symptoms from heat. 60% of participants stated that they have never used yoga to manage chronic pain, one of which stated that they never used but were interested. 10% of all participants stated that they are open to trying yoga to minimize symptoms. 50% of all participants stated that they have never used meditation, one of which stated that they never used but were interested. 10% of all participants stated that they are open to trying meditation to manage chronic pain.
Future Research •
The findings from this study suggests that people may be less open to trying yoga and meditation because it is time consuming and physically engaging. The methods that people were most open to trying were massage, heat, and ice, which are methods that do not require engagement. 30% of all participants preferred opioids to manage pain, and 2/3 of those participants acknowledged the harmful effect of continued opioid use. 60% of all participants acknowledged that the relief from alternative methods are not long lasting and not as effective as opioids. 60% of all participants reported that they discontinued use of an alternative method because it was no longer effective for managing pain. 30% of all participants stated that they discontinued use of an alternative method because it increased their pain or resulted in side effects. 20% of all participants reported that they discontinued the use of an alternative method due to cost or time. These findings suggest that people have difficulty finding alternative methods that provide them with long-lasting relief.
•
Future research is needed to examine emerging alternative methods for managing chronic pain and their effectiveness. Additionally, evidence is essential to identify if healthcare professionals are recommending alternative methods prior to prescribing opioids and if this trend correlates to the amount of people dependent on opioids to manage chronic pain. Future research on the themes found through the data analysis is crucial to provide more evidence to support the findings. Themes include arthritis as a source of chronic pain and massage and yoga as specific alternative modalities.

Discipline
Significance to Occupational Therapy Overall Re-admission
and What factors influence readmission rates to therapy caseload within a skilled nursing facility (SNF)?
Motivation for Research
COVID-19 has impacted the implementation of restorative maintenance programs (RMPs) within skilled nursing facilities (SNFs). RMPs can be defined as interventions that promote patients’ abilities to adapt and adjust to living as independently and safely as possible (Keiter & Sabo, n.d.). The SNF this study focused on changed its RMPs from five days a week (preCOVID-19) to three days a week (post-COVID-19) in hopes to limit the spread of COVID-19. These changes were made without knowing if three-day (post-COVID-19) RMPs were providing patients with the same outcomes as five-day (pre-COVID-19) RMPs.
Treatment Type
Gender
Future Research It is recommended that follow-up studies be conducted to better understand which factors effect readmission rates to RMPs within SNFs. It is important that future research studies screen additional facilities to further collect data (from the same time frame) to examine potential factors and utilize random sampling, as it was not used within this study (convenience sampling). These future studies would serve as an extension to this project to examine whether factors including five-day (pre-COVID-19) RMPs versus three-day (post-COVID-19) RMPs, gender, discipline, type of treatment, and payer source do/do not impact readmission rates or if additional factors exist.
Setting
SNF located in northwestern Pennsylvania and was chosen due to convenience sampling.

Discussion
Procedures Step 1 Step 2 Step 3
• Approval from SNF to utilize data within study. • Approval from the Internal Review Board (IRB). • OT and rehab director extracted data from medical charts and the RMP participation log.
• De-identified data released from the SNF to researchers January 2021, included medical charts and the RMP participation log. Step 4 Step 5 Step 6
• Researchers coded data. • Data analyzed and reported.
The significance of this study in relation to OT is to help identify what factors might play into a patient being readmitted into a RMP. Within SNFs, when a patient is readmitted to the therapy caseload, it is likely that the patient demonstrates a decreased ability to perform/participate in their meaningful occupations/daily routine. OTs provide a standard of care across multiple settings to allow patients to resume their daily lives/routines as independently as possible to successfully perform their needed/wanted occupations. Understanding which factors influence a person’s chance of being readmitted would allow therapists to adapt therapy services and/or the patient’s environment to decrease the rate of readmittance to RMPs. Additionally, understanding the rate of readmittance to therapy caseload probability when participating in OT is also of importance as it is likely not the care that is insufficient, rather the overall health and well-being of the patient.
Ø Discipline and treatment type demonstrated statistical significance. Ø Payer source, gender, and overall-readmission did not show statistical significance. Ø Specific to COVID-19, the study revealed that more people were being readmitted during three-day (post-COVID-19) RMPs versus five-day (pre-COVID-19) RMPs, however the difference was not statistical significant, thus indicating COVID-19 was not a factor in readmission rates. Ø The probability of being readmitted specific to disciplines includes OT only= 23.6%, PT only= 1.4%, and both= 75%. At first glance, OT appeared to not provide the same standard of care as PT. However, when paired with treatment types (OT=function based and PT=exercise based) it can be theorized that OT had higher readmission rates due to the population worked with. OT caseload (function based) treated more complex diagnoses/injuries. This can also explain the high readmission rate, 75%, for both OT and PT. A patient with a complex condition would be in need of multiple services and may have an increased chance of readmission.
PEO Model This research will be grounded in the Person-EnvironmentOccupation (PEO) Model which includes the interaction between the person, environment, and occupation.
Summary Reflecting on the research, it was shown that readmission rates in three-day (post-COVID-19) RMPs were higher than readmission rates in five-day (pre-COVID-19) RMPs, however it was not statistically significant enough to prove that a lesser number of days dedicated to RMPs due to COVID-19 caused an increase in readmission rates. Factors including discipline type (OT, PT, or both) and treatment type (function based, exercise based, or both) were found to affect readmission rates at a statistically significant amount.

Title: Restorative Maintenance Programs Prescribed to Patients in Skilled Nursing Facilities by Therapists Abstract: This study provides information regarding restorative maintenance programs (RMPs) within skilled nursing facilities (SNFs) by determining whether factors including five-day (pre-COVID-19) RMPs, three-day (post-COVID-19) RMPs, gender, discipline, type of treatment, and payer source impact readmission rates. A quantitative retrospect cohort design has been utilized due to RMP data being collected by a staff member from one SNF over the course of one year in which first half included data prior to COVID-19 with the second half including data post COVID-19. The data shows factors mentioned previously have little to no statistical significance impacting readmission rates. However, there were more readmissions within a three-day (post-COVID-19) RMP versus a five-day (pre-COVID-19) RMP. Also, patients who received both physical therapy and occupational therapy overall had an increased chance of readmission as well. The data reveals relevant and important information that can be applied to skilled nursing facilities regarding therapy treatment practices.

Services Offered to Veterans in Transitional Housing: Descriptive Survey Research PURPOSE To determine what types of programs and services are offered to veterans living in transitional housing and to determine if services available promote occupational justice.
Research Question What services are implemented in transitioning housing facilities for veterans in Pennsylvania?
Background • Occupational Therapy (OT) has been a profession for over 100 years. • Occupational Therapists, called reconstruction aides at the time, began treating wounded soldiers in WWI solidifying OT’s role in physically rehabilitating veterans. • Post WWI, federal funding became available to support vocational rehabilitation for veterans to help them transition back to civilian life and roles. • Since then, OT’s role in serving veterans has grown to include a holistic approach to address physical, mental health, and psychosocial needs. • Occupational Justice is “the right of every individual to be able to meet basic needs and to have equal opportunities and life chances to reach toward her or his potential but specific to the individual's engagement in diverse and meaningful occupation.” (Wilcock & Townsend, 2009) • The veteran population often experiences occupational justice barriers; especially the growing population of homeless veterans. • Transitional housing provides temporary residency and services to veterans unable to live independently due to hardships. • The reasons for veterans existing in the homeless population varies; some factors include but are not limited to: o Poverty o Substance abuse o Domestic abuse o Unemployment o Mental illnesses/ Disabilities o Incarceration • OT interventions in transitional housing may offer services to educate and motivate veterans to improve quality of life and promote the transition to independent living. • Interpreting the means of how facilities acquire the resources for transitional housing services will prove advantageous for the OT profession. • Research indicates further research needs completed regarding the implementation of OT services offered in transitional housing. (Hemphill, 2015; Louis, 2012; Tyminski et al., 2020; Wilcock & Townsend, 2009)
Data Collection Tool • Select Survey platform through Gannon University • Survey included broad questions regarding the facilities, services offered, and the veteran residents • Validity is a tool limitation because the survey relied on the knowledge/truthfulness of the staff of each facility.
Research Design • Quantitative descriptive survey • Best fit to help evaluate what programs are being implemented in transitional housing facilities in PA • Survey scripts were sent via mail and email to facility managers explaining the research study and purpose • Either a supervisor or employee knowledgeable with facility offerings completed the survey
Procedures • We sent out an email explaining the research study to the supervisors of transitional housing facilities located in Pennsylvania • The questions on the survey entailed yes or no, multiple choice, and open-ended
Results • 83 surveys disseminated; 6 returned • Results organized into three categories: facility demographics, service recipient demographics, and OT knowledge and use. Survey 1

• Q: Do you believe veterans could benefit by working with OTs? • A: Yes, many residents have applicable skills from service time that can be applied to civilian work. • Q: What are (if any) barriers to veterans receiving the services they require at your facility? • A: We provide what can be based on funding…we are limited to services supported by funding. • Q: Is there anything else you would like us to know regarding veterans living in transitional housing? • A: Having mental health/substance abuse treatment is essential. Finding jobs for those with criminal records is challenging.
Conclusion • There is a noticeable lack of OT services at the surveyed facilities. • Only one facility had an occupational therapist. • Many survey respondents understood the importance of occupational therapy and believed it would be a beneficial service to have at their facility. • Facilities do provide services in the areas of transportation, finances, life skills, and mental health. • Many of these transitional housing facilities rely on community donations, federal/state funding, and private foundation grants to provide services. • Each facility varied in size, staff, number of veterans housed, and length of stay. • Many services seemed to center around mental health and substance abuse treatment. • A larger sample size would be beneficial for truly understanding the services and facilities that are assisting homeless veterans.

• The goal of transitional housing facilities is to provide temporary support to veterans to assist them in regaining their independence and improving their quality of life. • Holistic and client-centered occupational therapists can benefit vulnerable veterans in these settings because Occupational Therapists can assist veterans in regaining their ability to complete everyday activities and improve their quality of life. • The lack of OT services in transitional housing could be a barrier to veterans as they seek occupational justice. Occupational Therapists can use an occupational justice platform in these settings to promote and advocate for OT services. • Occupational Therapists should advocate for their role in transitional housing facilities and prove their distinct value in this setting. Veterans could benefit from OT in the areas of: • Activities of Daily Living • Instrumental Activities of Daily Living • Vocational Training/Rehabilitation or Volunteering • Health Management and Wellness (physical and mental) • Nutrition/Meal Planning • Leisure Participation • It may be beneficial for Occupational Therapists to seek out funding for the services they wish to provide in transitional housing settings (grants).

ability to apply it to practical problems.
When looking at those who have survived a CVA, also known as stroke, many new challenges are present for these individuals. One area that is less explored is sexuality, both for survivors and their partners. Research exists identifying interventions and challenges for this population and investigates gaps in treatment and areas where intervention is effective. Guided by our research question, this review seeks to identify common themes and areas were more research is warranted. Findings from this study indicate that while many challenges are present due to both physical and mental changes post-stroke, there are also interventions being developed to address these. Overall, there continues to be a lack of attention paid to sexual function after CVA and further research is needed to determine the effectiveness of interventions to address the impact of sexual function. Cerebral vascular accident (Stroke) occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts (ruptures). When that happens, parts of the brain can not get the blood and oxygen it needs, brain cells begin to die. Stroke is the 5th leading cause of death within the US, every 40 seconds someone has a stroke (Center for Disease control and prevention, n.d.).

There is a lack of research regarding more diverse individuals within the stroke survivor population. The majority of research exists based on heterosexual males. The ability to implement the interventions within the research and the effectiveness of said interventions may be impacted by the comfort level of the practicing clinician Due to the minimal research on evidence-based interventions, there are still gaps in intervention areas that need to be addressed. Research exists for some pharmacological options as well as education and physical compensatory techniques, but more information is needed in areas such as mental health and female anatomical functioning to increase applicable and useful interventions. While this research was conducted through the lens of occupational therapy, only three studies out of ten included interventions that utilized occupational therapists. Relation to Occupational Therapy
Sexual dysfunction is commonly associated with stroke and OTs have a strong knowledge base in physical disability. With sexual activity being an ADL, it is appropriate for OTs to create interventions for finding and implementing comfortable positions, modifying and adapting environments, and providing education on overall health and well-being. OTs are experts on analyzing client factors and performance skills, both of which are impacted by stroke. · OTs also have the ability to advocate for patients undergoing rehabilitation for stroke to help ensure that sexuality is addressed by the healthcare team. Lastly, sexual dysfunction after stroke creates challenges for the Individual (Micro), Organizational (Meso), Community (Macro). Conclusion This study sought to explore the issue of the impact of stroke on sexuality and the available interventions to address this. The researchers did so by selecting ten articles of level three evidence or higher and completing critical appraisals for each study. The CAPs were then read and discussed among each researcher to identify themes across the research as well as available interventions. The most common themes were stroke survivors being limited by physical and mental changes poststroke. Depression was found to be the most common mental disability that limited this population in their sexual abilities. This was also the most common change that impacted sexuality discussed among partners of stroke survivors throughout the research. The most common issue with actual implementation of interventions addressing sexuality within the rehabilitation was found to be the comfort level and experience of the clinicians. These findings show that the initial research question has a multifaceted answer. Many impacts were identified as well as many interventions, but the lack of research primarily lies in the latter half of the question: intervention. Because of this, research in this topic area moving forward should focus on creating and implementing evidence-based interventions addressing sexuality. Overall, more research is needed to create and implement evidence-based interventions addressing the many ways stroke impacts sexuality for both the survivor and their partner.

Title: Sexuality and Stroke: A review of Impact and Current Interventions Abstract: When looking at those who have survived a cerebral vascular accident (CVA), many new challenges are present for these individuals. One area that is less explored is sexuality, both for these individuals and their partners. Research exists identifying interventions and challenges for this population and investigates gaps in treatment and areas where intervention is effective. Guided by the question, “Is sexuality impacted by CVA for both the survivor and their sexual partner and what interventions are available to address sexuality in this population”, this review seeks to identify these common themes between the existing research while also analyzing where further research is needed. Findings from this study conclude that while many challenges are present due to both physical and mental changes post-stroke, there are also interventions being developed to address these. Overall, further research is needed to determine the effectiveness of these various interventions and potential new interventions.

Title: Sleep Related Stress Management for College Students Abstract: Stress levels can be negatively impacted by sleep quality in college students. This project sought to determine if occupational therapy video module intervention impacted stress levels and sleep quality in college students. Participants completed five weekly video modules that provided education regarding sleep hygiene, environmental modifications, meditation and mindfulness, exercise and yoga, and sleep ergonomics. The Perceived Stress Scale (PSS) and Pittsburgh Sleep Quality Index (PSQI) served as the pre-test/ post-test measures. While the participants did not demonstrate a reduction in perceived stress following participation (p=0.20) in this study, they did demonstrate improvements in sleep latency, sleep disturbances, and daytime dysfunction. Additionally, the PSQI global score indicated occupational therapy video module interventions may have improved global sleep dysfunction in college students. This data suggests that the use of occupational therapy video-based sleep education modules may improve sleep quality.

Title: The Effects of The S.U.C.C.E.S.S. ApproachSM on Adaptive Behavior and Occupational Performance in Children with Autism Abstract: Occupational therapists have expressed a desire to increase the effectiveness of their treatment for autism spectrum disorder (ASD). Although there are several treatment options for ASD, including occupational therapy, no specific treatment has been identified as the most effective. This research study examined the efficacy of The S.U.C.C.E.S.S. Approach (TSA), which is an emerging occupational therapy practice model for individuals with ASD. Throughout the study, the Canadian Occupational Performance Measure and the Pervasive Developmental Disorder Behavior Inventory were utilized to examine changes in occupational performance, adaptive behavior, and maladaptive behavior in children with ASD after eight weeks of TSA intervention. The findings of this study bring occupational therapy practitioners closer to understanding the most effective intervention model for treating individuals with ASD.

Title: The Impact of Education on the Adverse Effects of Breast Cancer Treatment for Breast Cancer Survivors: A Case Study Abstract: This case study aimed to better understand the impact of adverse effects of breast cancer treatments and the benefit of a post-breast cancer education session on quality of life. The cancer survivor received an education session detailing four common adverse effects (fatigue, skin appearance changes, cognition, and mental health) and management strategies for these effects. Data was collected through a Pre- and Post- Survey designed to identify the impact of adverse effects post-cancer treatment on quality of life and the benefit of an education session detailing the effects. Survey responses indicated that strategies presented during the education session decreased the impact of the adverse effects on the participant’s quality of life. Education about the adverse effects of breast cancer treatment should be communicated to survivors to foster success with daily life after cancer. Further research is needed to understand the effectiveness of education to improve quality of life post-breast cancer.

Title: Using AI on Git Repository Data to Predict Fault-prone Components and Analyzing the Evolution in Rapid Releases Abstract: Prediction of fault-prone components at an early stage is very much useful for any organization to ensure quality software delivery. With the prediction of fault-proneness of the components, prioritizing tests becomes easier. Software testing teams can allocate more resources to “High” fault-prone components instead of spending more time on “Low” fault-prone components. This will help reduce the cost of the bugfix and regression work and will allow developers to make early and careful decisions about the sensitive components. This paper focuses on two aspects. First, we construct and compare the prediction models SVM, Naive Bayes, and Random Forest for classifying components as “High” or “Low” fault prone for the open-source projects Chromium web browser. Second, we analyze the evolution of this fault proneness in 44 releases of Chromium. We apply repository mining techniques to collect the commit history, and we collect the bug records from their bug tracker systems. Since the chromium repository is extremely large in size having 1.16M commits, in this paper we consider the last five years of commit history. There are 26 components we found for Chromium and 44 major releases (from release 50.0 to 93.0) with a median of 62953 commits per release with a standard deviation of 40472. The key factors involved to construct the prediction models are the number of total churns, percentage of bug-fix commits, overall bug-fix churns, last minute bug-fix churns, number of developers involved, overall last-minute churns, and number of files modified. Based on these attributes our models are able to predict the fault-proneness of the components. We found ``Platform’’ is one of the ``high’’ fault prone components, and ``Enterprise’’ is one of the ``low’’ fault prone components in Chromium. We compare the accuracy of Random Forest, SVM and Naive Bayes prediction models. Random Forest outperformed the two others. with an accuracy of 94 % while Naive Bayes and SVM showed an accuracy of 35% and 88% respectively.

Virtual Reality Video Games: A Cross Cultural Study of Psychological Needs Kevin Paton
Jinhee Yoo (Advisor)
Introduction
There are over 2.43 billion video game players in the world as of 2018. The virtual reality VR industry is expected to have a cumulative annual growth rate of 21.6% from 2020 to 2027. Pushing the value of $10.32 billion in 2019 to $48.76 billion. The better game developers can understand the subtle nuances that cause differences in experience the better developers can create more compelling products to take advantage of these large emerging markets. From 2014 to 2019 global eSports revenues went from $194 million to projected $1.072 billion. Viewership of eSports also increased from 90 million to projected 215 million consistent fans. The incredible growth in these areas sparks a need for further understanding of the potential market for these industries to combine. The purpose of this study is to see if nationality has an influence on the users experience when using VR video game technology. Research Question
Does nationality influence the user's experience? Literature Review
This study is grounded in Self-Determination Theory (SDT). SDT addresses the motivations behind human actions in order to satisfy their needs (Yoo et Al., 2022). SDT also allows for a glimpse into the dimensions of Autonomy and Competence that humans need at their core (Yoo et al., 2022). Autonomy is one’s ability to self govern. Competence is the ability to do something successfully. The use of VR allows users to have an increased sense of realism within a virtual environment. The scene of realism and immersion can be broken into two main, subdivisions mental and physical (Suh et al., 2018). This study is focusing on the mental levels of immersion through psychological gratification. Immersion shares a linear correlation with appeal when looking at video games (Christou, 2014). Recent studies are looking into the expansion of video games, one study showed that nationality did not affect video game participation preference, although it did affect the intensity of participation (Garcia et al., 2020). Studies also show different levels of intensity in gaming dramatically shifts the preferences within what they seek when gaming (Scharkow et al., 2015). Exploring this to see vary levels of intensity equates to altered psychological factors. This stands to reason that nationality could in turn affect the experience in gaming. VR games presenting users with potential new skills can be seen as a potential factor that intrinsically motivates them (Yoo et al., 2022). Similarly exploring the opposite
is important. Are there external factors that effect the user's psychological needs? This is explored with the questions on external regulation. Amotivation is the lack of intention to engage in behaviors and is considered to be a non-self-determined kind of regulation (Martkland et al., 2016). Leaving intrinsic motivation, this is the motivation that comes from within oneself. It is with these psychological factors that this study looks to gather further insight, specifically around the realm of VR sports video games. Method
Participants came from a university in the United States and a university in Nigeria. There was a total of 29 individuals, 14 from Lagos Business School in Lagos Nigeria, and 15 from Gannon University in the United States. Participants were brought to a lab and instructed on how to play the VR Sports Challenge Football Game using the Oculus Rift©. Participants were asked to complete a survey after they completed the experiment. Survey questions using a seven-point liker scale. As well as asked open ended questions based on their experience within the VR game they played. The questions were to measure their perceived levels of Competence, Autonomy, Intrinsic Motivation, Identified Regulation, External Regulation, as well as Amotivation.
Findings
Discussion
The results from the analysis are displayed below. The nationalities are listed Lagos Business School (LBS) and Gannon University (GU), are the representatives for Nigeria and the United States respectfully. The average of all participants was also listed as a reference point. There was little discrepancy between the two nationalities, and the average. There was roughly similar differences between Nigeria and the US for five of the six categories. Autonomy, and identified regulation were roughly half a point higher favoring Nigeria. Where as Amotivation and Competence favor the US by less then half a point. Intrinsic motivation was nearly identical being only 0.03 points off favoring Nigeria. The largest difference that was found was within external regulation. This had a staggering 1.53-point favorite. This was the largest margin of difference by a factor of 2.78.
play video games, we also have information on how much money they spend a year on video games. There was a similar trend where participants in the US appeared to spend significantly more then their Nigerian counterparts. These two factors combine show that the level of experience and interest in video games as well as VR sports video games could be influenced. Further studies should examine the potential correlation between external regulation with VR video games and frequency and interest in video games.
Discussion
There are certain demographic characteristics that should be considered as we examine the data. The leading psychological factor discrepancy between two nationalities is “External Regulation”. When looking at the two cultures and the demographic information that was collected, we can draw a few conclusions. We surveyed the participants and had them answer questions based on how often they played video games. The participants from the US had an even distribution of answers ranging from daily to less then once a month. The interesting factor was found with the participants from Nigeria were all, but one participant said they play video games more then once a month. In addition to the frequency of how often the users
Limitations
It is important to acknowledge within this study that there was significant limitations brought on not only by scale but the COVID-19 pandemic. When examining the scale of this study there are obvious limitations. There were only 29 total participants. With less then 15 from Nigeria. Given expended time and resources ideally this kind of study could cross examine individuals from a diverse set of cultures with participant populations in the hundreds. There were also limitations with Gender and Age. The entirety of the US population surveyed were under the age of 25. Whereas in Nigeria there was only one female participant. These are not conducive of an entire population.

Data Analysis
The data from the 29 surveys was collected and complied into a Microsoft Excel© file. The complied data was organized by the individual as well as the nationality they fell under (US and Nigerian). The data was then organized based on the main psychological areas of study (Competence, Autonomy, Intrinsic Motivation, Identified Regulation, External Regulation, Amotivation) as well as
their demographic information and any responses to the open-ended questions. Each of the psychological factors had four questions developed to examine the user's experience. Subsequently, the scores were averaged out for each person for each category. Then averages were generated for each of the nationalities were developed.

Title: Virtual Reality Video Games: A Cross Cultural Study of Psychological Needs Abstract: This study is developed around self-determination theory to help examine if virtual reality (VR) can help meet individuals’ psychological needs while playing a VR sports video game. In this study data was collected through online surveys given to participants following a series of VR sessions. They answered questions on their perceived levels of Competence, Autonomy, Intrinsic Motivation, Identified Regulation, External Regulation, as well as Amotivation. These areas will help developers better understand the phycological drive to use VR equipment. There are over 2.43 billion video game players in the world as of 2018 (Baltezarevi_ et al., 2018). From 2014 to 2019 global eSports revenues went from $194 million to projected $1.072 billion (Willingham, 2018). Viewership of eSports also increased from 90 million to projected 215 million consistent fans (Willingham, 2018).

Occupation
Significance to Occupational Therapy Ø Occupational therapy practitioners are skilled at evaluating and addressing influences from the person, their activity roles and routines, and the environment to maximize independence for older adults. Ø Practitioners can identify environmental factors that contribute to falls and implement occupational therapy strategies to ameliorate these elements, which can improve safety and reduce health care costs while enhancing the participation of older adults in those communities. Ø Unveiling the theme of falls within a site-specific facility will allow the practitioner to determine the best course of action to reduce falls.

Title: When and Where do Falls Occur in a Skilled Nursing Facility Abstract: Falls in long-term care are on the rise, which is problematic for older adults and the healthcare system. When developing a fall prevention program, understanding the places and times that falls occur is essential. This study sought to identify the trends of falls according to where and when falls occurred in one skilled nursing facility using previously collected de-identified data. Results found that 45% of falls occurred between 3 pm and 11 pm, and 66.37% occurred in patients’ rooms. These findings will aid in the development of a site-specific fall prevention program.

Methods
Scan to view video of robot-based intervention
Introduction
• It is common for individuals with autism spectrum disorder (ASD) to have deficits in communication, specifically in pragmatics and expressive/receptive language. Different therapy techniques help these individuals gain social and communication skills. • In recent years, the use of robots has been tested as a therapy option. • In this review, eight articles comparing robot-based intervention to human basedbased intervention were assessed for their efficacy with individuals with ASD. • The randomized control trials included in this review assessed robot intervention as compared to human interactions in the areas of social/emotional skills, play skills, joint attention, communication skills, between partners, gestural production, motor skills and spontaneous verbal responses in social communication.
Skills Gained Per Intervention Method
(So et al., 2019)
• Participants in the studies included children with ASD between the ages of 4-12 years old who showed deficits in social communication, specifically in pragmatics and expressive/receptive language. • All participants showed moderate to severe symptoms of ASD, and there were no group differences in terms of levels of autism severity. • Each study used standardized tests to assess and evaluate the children’s communication abilities and social skills. • During the first weeks of the studies, trained experimenters conducted pre-tests in random order across participants to gather baseline data and to ensure that participants met criteria for intervention, and post-tests were conducted after study completion to evaluate communicative progress. • Children were randomly assigned to either rhythm (imitation-based music and movement activities), robot, or comparison groups. • Therapy sessions ranged from 9 to 12 weeks. • Rhythmic therapy was delivered by humans, and robotic therapy, including games, activities, and narrative dramas, was delivered by robots. • Robot-based and human-based sessions were administered by trained researchers. • Parents gave consent for all participants to partake in the studies and completed questionnaires prior to intervention.
Results
• In experiments focusing on gestures with robots versus humans, no significant difference was found between the type of communicative partner involved. • The experiment that focused on motor control showed that robot-based intervention paired with human intervention was key to further developing gross and fine motor skills during interactive play. • Experiments focusing on communication skills between partners were found to have a higher response to robot intervention regarding eye gaze and imitation when compared to the human control group. • Experiments focusing on cognitive behavioral therapy using robots versus humans, children in the robot group showed significant improvements in performance of the five basic emotions and in shame equally with humans and robots. • The experiment that focused on spontaneous verbal responses in social communication found more responses elicited by human-based intervention than robot-based intervention. • The experiment focusing on joint attention and functional play behaviors of children with ASD found that children with the robot group interacted more frequently with more utterances and less prompts than those in the human control group.
Discussion & Conclusion
• The results of the eight articles reviewed in this study suggested that children with ASD benefit from the use of robot-based intervention alone or paired with human intervention in all cases except spontaneous verbal responses in social communication. • Specifically, improvements were noted in social/emotional skills, play skills, joint attention, and communication skills between partners with robot-based intervention. • Findings indicated that children with ASD gained skills of gestural production, gross and fine motor skills, and emotional recognition equally through human-based and robot-based intervention. • Spontaneous verbal responses in social communication were elicited at a higher rate with humanbased intervention than robot-based intervention. • Currently, robots are used to assist SLPs in therapy with children with ASD in their speech outcomes depending on communication goals. • Further research should be conducted to evaluate the use of robots more individualized to children’s needs, and studies with greater sample sizes may make this intervention improve external validity. • • • • • •
Limitations Sample sizes were limited to 14-40 participants. Studies included only children. Samples were limited in external validity. Lack of long-term follow up Limited intervention duration Cost and access to robots may be preventative.

Improving Intelligibility For Individuals With Dysarthria
Rita Lenhardt, D.H.Sc., CCC-SLP Contact: miller316@gannon.edu
Introduction Dysarthria is a neurogenic motor speech disorder typically resulting in impaired intelligibility, which is why improving intelligibility is often the target of speech therapy. The aim of this poster is to identify evidence-based intervention approaches for individuals with dysarthria focused on improving intelligibility in conversational speech. The evaluated treatment approaches target subsystems of speech affected by dysarthria, including respiration, phonation, articulation, resonance, and prosody. The Six Character Formula Technique, brain stimulation therapy, the Beatalk method, and speech cues are interventions found to be effective in improving the speech intelligibility of the individual with dysarthria.
Methods A systematic review of current literature was conducted. Eight peer-reviewed articles were selected about the four dysarthria interventions, two of which were randomized-controlled trials. Subjects were chosen based on their diagnosis of mild to severe dysarthria resulting in reduced intelligibility. Articles were excluded if they were published prior to 2015 and did not have a speech-language pathologist collaborator/author.
Results 1. Six Character Formula Technique ○ The Six Character Formula Technique, also called Liuzijue Qigong, is a Chinese traditional exercise that focuses on breathing–speech synchronization. ○ Researchers compared the use of The Six Character Formula Technique to traditional breath support. There were statistically significant differences for the experimental group based on the results of the modified Frenchay Dysarthria Assessment, maximum phonation time, and maximal counting ability. However, no statistically significant differences were found in the s/z ratio or changes in loudness level between the two groups.
Conclusion
2. Brain Stimulation ○ Brain stimulation therapy involved implanting a stimulator into the brain, and then switching the divide on and off to stimulate the brain. Some non-invasive methods use electrodes on the skull for stimulation. ○ Improvements in intelligibility were shown to last at least eight weeks following intervention. There was a change in brain activity not only to the stimulated region, but to articulatory regions as well. ○ It was shown that brain stimulation causes more imprecise articulations in speech, ultimately decreasing the intelligibility of an individual.
3. Beatalk Method ○ This is a form of speech therapy that involves the imitation of beatboxing rhythms and sounds in an acapella music context. ○ The Beatalk intervention had a significant overall pre-to-post-treatment effect. It resulted in improvements in articulatory accuracy and intelligibility for single words.
4. Speech Cues ○ Speech cues are verbal instructions given by the clinician to modify the speaker’s production. ○ Speech cues for clear and loud speech were found to be effective in improving the intelligibility of speech in children with dysarthria, as rated by adult listeners. ○ Two structured speaking tasks used in one study were: slow speech and habitual speech. There was greater improvement in intelligibility for longer utterances using the slow speech method. Intervention

More Research Needed
Limitations
1. Six Character Formula Technique: is a preliminary study and it was a short term study. 2. Brain Stimulation: only mild cases were included in the studies. 3. Beatalk Method: a small sample size was utilized, making the studies external validity limited. As a result of a short intervention period of eight weeks, fewer consonants were targeted. 4. Speech Cues: small sample sizes were utilized. More research is needed to determine effects on generalization and maintenance.
Recommendations Future research should further explore the effects of brain stimulation, Six Character Formula Technique, and the Beatalk method on intelligibility. Generalization of speech production changes due to speech cues also requires further study.

Brain Stimulation Beatalk Method
Ineffective
Based on the evidence studied in this poster, speech cues and the Six Character Formula Technique were found to be effective interventions in improving intelligibility for individuals with dysarthria. Brain stimulation requires further study to determine if there is a statistically significant effect in increasing intelligibility. The limited research found supported the Beatalk method, however, more definitive evidence is required.

ADHD and Bipolar Disorder in Children and Adults
Introduction
• Highest diagnosed mental illnesses but can also coexist side by side • Few studies demonstrate how the two disorders can coexist with each other. • wide range of symptoms and patient knowledge • both ADHD and bipolar disorder can be diagnosed during childhood and adolescence • ADHD can also be a precursor to bipolar disorder, causing a trial of treatments until the correct regimen has been established. • When each disorder coexists with each other, the diagnosis and treatments become even more challenging • Misdiagnosis or mismanagement of the disorders can lead to hospitalizations, failure in daily tasks, and overall poor quality of life • Nonpharmacological therapies are also beneficial for patients and their families • Behavioral therapy and psychoeducation aid in preventing relapse
Studies
Research was compared between 14 different published journals to determine the best course of treatment for those with ADHD, BD, and when they coexist together in both children and adults. Information Included - Risk factors - Family history correlation - DSM V criteria - Diagnosis scales and resources - Medications for acute episodes and long term therapy - Nonpharmalogical treatments
Discussion
• ADHD and Bipolar Disorder are two of the leading mental illnesses in the US • very little research and information about progression and treatment • Many studies demonstrate that the initial diagnosis of bipolar disorder will present with ADHD-like symptoms during a manic episode • ADHD can present with many outbursts and temperament issues during childhood • DSM-V criteria does not fully differentiate the two disorders due to the similarity in symptoms • different scales and questionnaires to further expand the diagnoses • Males with ADHD are commonly mislabeled as “problem children,” • females are seen as not caring and lazy

Results and Treatments
• Wrongful diagnosis can be detrimental to a patient’s quality of life • Treatment for ADHD includes stimulant use (such as methylphenidate) and cognitive behavioral therapy • Treatment for bipolar disorder uses mood stabilizers and antidepressants for long term control, and antipsychotics as the drugs of choice for acute and severe psychotic symptoms • When ADHD and bipolar disorder coincide with one another, treatments can include many different medications to create a solid regimen for the patient • Typically follow the foundation of a mood stabilizer with an antidepressant, followed by a trial of stimulants to treat the ADHD • When left untreated or improperly treated, patients are at risk for declining productivity at work and school, along with social and familial impairments • Non-pharmacological therapies (psychotherapy, CBT, exercise, art activities, etc.) should also be included for the best possible outcomes

Title: ADHD and Bipolar Disorder in Children and Adults Abstract: ADHD and Bipolar Disorder in Children and Adults review studies that aid in diagnosing and treating the disorders throughout a patient’s life. This review of literature will distinguish the difference between the two disorders, as well as determine a plan when the two disorders coincide. It will also discuss treatments apart from pharmacotherapy and how to incorporate activity modifications into daily routines. Studies included in this paper concluded ADHD and bipolar disorder can be treated separately if diagnosed with one or the other, but when the two disorders are found together, a different regimen must be established by trial and how the patient responds.

Title: Tikkun Olam through Vaccination Abstract: There is a strong correlation between low immunization rates and high infectious disease rates within the Orthodox Jewish community of Brooklyn, NY. Disease outbreaks that occur are usually discovered to spread rapidly throughout their insular school systems and large families. Since this is a very community-oriented group, highly transmissible diseases often jump from family to family and drive up the rate of infections. The common misconceptions that interviewed mothers have about vaccinations parallel those identified by the American Academy of Pediatrics. Development of this community public health program, Tikkun Olam through Vaccination, specifically addresses the concerns with a culturally sensitive and centered approach may reach more members of the community and educate them about the importance of immunizations, therefore decreasing the disease rate and increasing the immunization rate of the Orthodox Jewish children in Brooklyn.

Introduction: •
•
Cerebral Palsy is a neurodevelopmental disorder caused by nonprogressive lesions in the developing brain CIMT is composed of three components which include constraining the non-affected arm, repetitive and intensive motor activities of the more affected arm, and shaping functional movements of that affected arm
Methods: •
Comprehensive overview of the literature from several databases
•
Inclusion criteria of CP diagnoses, younger than 18 years old, CIMT or mCIMT intervention
•
Key words of CIMT, occupational therapy, cerebral palsy, pediatrics, children
References:
Of the 24 studies reviewed in this systematic review 21 were randomized controlled trials (RCTs) and the remaining 3 were one/single group pretest-posttest designs. The most common outcome measures were the Assisting Hand Assessment (AHA) and Jebsen-Taylor Test of Hand Function (JTTHF). 14 of the 24 studies utilized the AHA in their research and 7 of the 24 studies utilized the JTTHF. 21 of the 24 studies were level II. All studies showed CIMT to be effective in improving upper extremity function. Many of the level II studies demonstrated that children were able to improve their upper extremity movements for various functional skills. De Brito Brandão et al., (2012) demonstrated that CIMT intervention could be utilized to improve functional skills and self-care activities. The results of the studies within this systematic review demonstrate that CIMT is an effective intervention to improve various upper extremity functions.
India Brown Breanna Flaherty Adam Regalado Lindsee Zimmer
Discussion: •
• •
Although there is sufficient evidence on this topic to conclude that CIMT is effective, an improvement to the evidence would be the inclusion of more level I studies. Systematic reviews and meta-analyses including strong randomized controlled trials could be performed to further improve the evidence. Additionally, skilled rehabilitative therapists should research and be competent in administering this therapy before utilizing CIMT with pediatric clients.
Conclusion: •
The data gathered from these 24 studies support that over the past 27 years, CIMT has shown to be a beneficial and effective treatment when used to improve upper extremity function in children with CP. Due to these results, the hypothesis would be accepted.

Title: Is mirror therapy, in conjunction with conventional treatments effective in improving UE function in stroke patients? Abstract: Background: There is a high prevalence of stroke in the United States and other developed countries. Mirror therapy (MT) is one of the most widely used treatments for patients who have experienced a stroke. MT along with conventional therapy has shown evidence to be more effective in enhancing upper limb function for patients. Methods: A systematic review was conducted. The search string was based on a previous systematic review about mirror therapy dated in 2016: “mirror therapy” AND “stroke” AND “occupational therapy” OR “function”. For this search PubMed, CINAHL, SPORTDiscus, Google Scholar, and EBSOhost databases were used. Results: Twenty-four studies were included in the systematic review. Upper extremity function and performance in ADLs were the most frequently measured outcomes in these studies. Conclusion: The use of MT along with traditional post-stroke rehabilitation can lead to improvement in UE motor function and independence in ADLs.

Systematic Review of Neurodevelopmental Treatment in Children with Cerebral Palsy By. Maria Bravo OTS, Katlyn Ernst OTS, Anna Ingram OTS, Mimi Uwase OTS, Alicia Warren OTS
Introduction
Overall concept pf NDT is to promote desired muscle activation, correct abnormal movement patterns, and restore normal movement patterns. NDT can be effective when paired with myofascial release, casting, pressure splinting, and oral-motor activities. Even though NDT is one of the oldest and most utilized interventions to treat children diagnosed with CP, some past researchers have stated there is little to no evidence that NDT can increase functional skills. This made this systematic review important to conduct to promote any findings on effectiveness when NDT is facilitated alone or when paired with other treatments.

Results Question: Is NDT a more effective treatment to increase motor movements for activities of daily living when compared to more conventional treatments in children with cerebral palsy? Successful paired with other treatments: NDT with the Johnstone pressure splints had a statistically significant effect in PROM p<0.0, MAS p<.0.05, and Somatosensory P<0.05 Successful on its own: NDT administered on its own, on the GMFM it scored statistically significant in walking, crawling and in ages 2-6 with walking, as well in the GMFM- 66 Not successful when paired with other treatments: On the Quality of Upper Extremity Skills Test (QUEST), there was no statistical significance between children receiving intensive therapy plus casting vs. children receiving regular OT (Law et al., 1997). Not successful on its own On the GMFM-88 there was no significance in walking, running, or jumping (Labaf et al., 2015). Outcome Measures used: The outcome measures that were used were the gross motor functional measure, PEDI, Goal Attainment Scale, Quest, Functional Independent Measure (with children).
Discussion
• NDT found effective when combined with other therapies. Reject hypothesis • Clinical Practice: Avoid implementing NDT as a solitary treatment • Future Directions: What therapies are most effective when combined? Limitations: Long-term effects not assessed. Most studies published in foreign journals. There are small sample sizes. Other factors might have contributed to outcomes.
Conclusion
NDT was found effective when combined with other therapies Reject hypothesis/hypothesis For clinical practice, therapists avoid implementing NDT as a solitary treatment. Since there is not enough research to support its use solely. Further research needs to answer the question: What therapies are most effective when combined?
Title: Systematic Review of Neurodevelopmental Treatment in Children with Cerebral Palsy Abstract: Identifying effective interventions to address upper extremity issues in children with cerebral palsy (CP) is an ongoing challenge. A systematic review was completed to determine if a common motor intervention, neurodevelopmental treatment (NDT), was an effective in improving upper extremity movement compared to other methods. A total of 24 articles were included in this review. The results indicated that NDT alone was not an effective intervention to improve upper extremity movement. However, efficacy increased when NDT was combined with other interventions. This poster highlights the findings of this review and provides recommendations on effective approaches to improve upper extremity movement.

Treatment Outcomes Review: Childhood Apraxia of Speech
Dr. Rita Lenhardt, CCC-SLP Introduction:
Methods:
• Childhood apraxia of speech (CAS) is a neurological speech sound disorder that results in impairments in the motor planning and programming of the oral articulators leading to unintelligible speech. • Thousands of children are affected with CAS, either as a primary or comorbid disorder, yet effective treatment methods remain relatively understudied. • Given that CAS is a speech sound disorder, speech-language pathologists can provide therapy using an articulatory, MotorBased, or Phonological-Based approach for treatment. • Although articulatory and phonological-based treatment methods are beneficial, a review of recent findings indicates that intensive, motor-based approaches are more effective for the treatment of CAS. • CAS is often misdiagnosed as it could be mistaken for a fluency or language disorder. Expressive language skills are impaired, but receptive language skills remain intact. • The main symptoms are facial groping and inconsistent error patterns. • Motor-Based Approach focuses on how speech articulators move. This includes features such as one’s lips, tongue, teeth, and hard/soft palate. • The aim of Motor-Based Approaches are to produce accurate movements to help with the production of speech. • Phonological-Based Approach focuses on improving target sound productions. • The aim of Phonological-Based Approaches are to teach the client sound productions and decrease any error patterns that the client may present with.
• A literature review was conducted, which resulted in eight studies being selected. All articles were apart of randomized controlled experiments. Before beginning any procedures, participants were required to pass a bilateral hearing screening (1000, 2000, 4000 Hz), oral mechanism examination, as well as not have any other language impairments or comorbid disorders. • The main population focus were children, and they ranged from the ages of 32 months-12 years old. • The studies included children with CAS who were phonologically and articulatory impaired, but there was a criteria (e.g., inappropriate prosody and rate, voicing errors, and inconsistent errors) that needed to be met. • Children with CAS were compared to typically developing (TD) children. • Children were placed in intervention for an average of six weeks and their performance and progress was evaluated before, during, and after treatment.
Results: • Based on our findings, an average of forty-five minutes to hour long sessions of intensive treatment took place, several times a week up to ten months. The average treatment took an average of six weeks. • Treatment methods included high intensity oral motor techniques and phonological approaches which were used in treatment sessions. • One study has success which focused on using oral motor techniques reducing the cognitive demand, which used imitation as a technique to decrease articulatory variability in speech. • After intensive treatment was completed, various assessments were done in order to judge treatment efficacy. Some of these assessments included the Diagnostic Evaluation of Articulation and Phonology (DEAP), the Goldman Fristoe test of Articulation Second Edition (GFTA-2), the Test of Abstract Language Comprehension Third Edition (TALC-3), and the Bankson-Bernthal Test of Phonology Second Edition. A speech sample was obtained as well.
Conclusions: • There is a lack of research on the topic of interventions for childhood apraxia of speech. • Motor-Based Approaches and Phonological-Based Approaches are both widely used in the therapeutic intervention of CAS. • Although both treatment methods are widely used, based on our research, Motor-Based approaches are more effective in treatment. • Research indicates that this may be due to the tactile and kinesthetic components of treatment benefitting those with CAS. • It is important to remember that there is not enough research to conclude which method of treatment should be used when working with CAS. • Clinicians should implement motor-based approaches during therapy, as it seems to be the most effective.
• •
Limitations:
Based on the findings, further research on this topic would be recommended to enrich evidence-based practice in this area. Low incidence rates limit same size.
Recommendations: 1. Continued research for both Motor-Based Approaches and Phonological-Based Approaches are necessary to explore treatment efficacy. 2. Continued education for Speech Language Pathologists and emphasis on proper diagnoses of Childhood Apraxia of Speech.

Title: Treatment Outcomes Review Childhood Apraxia of Speech Abstract: Childhood apraxia of speech (CAS) is a neurological speech sound disorder that leads to impairments in the motor planning and programming of the oral articulators and thus leads to unintelligible speech. Thousands of children are affected with CAS, either as a primary or comorbid disorder, yet effective treatment methods remain relatively understudied. Given that CAS is a speech sound disorder (SSD), Speech-language Pathologists (SLPs) provide therapy and focus on using either articulatory approaches, motor-based approaches, or phonological-based approaches for treatment. Current research suggests that while phonological-based treatment methods are helpful, speech intelligibility is increased more effectively with intensive, motor-based treatment approaches.

Evaluating Different SI interventions on Challenging Behaviors and QoL in Children with Autism Question
Background
-Sensory integration is an evidence-based
framework for treating individuals with sensory integration dysfunction -Children with SID are unable to complete specific daily tasks due to physiological disturbances resulting from SID -Children present learning disabilities and/or behavioral issues due to SID -SIT decreases challenging behavioral issues and learning difficulties in children with SID. -SI has been used since 1970s but there is still controversy about the effectiveness of SIT
What are the different sensory integration (SI) interventions that address challenging behavior and quality of life of children with autism?
Systematic Review
Three stages: -Search strategy: PubMed, Nash Library, SagePub, AJOTA, EBSCO, NCBI; Search terms:‘sensory integration’, ‘autism spectrum disorder’, ‘children’, ‘pediatric’, ‘experimental’, ‘occupational therapy’ -Study selection: inclusion criteria: pediatric population, SI treatment interventions, and children with ASD; exclusion criteria: sensory aspects -Data analysis: 4 researchers selected studies after considering inclusion and exclusion criteria, and meaningful outcomes.
Andrea Herrans, Melissa Lamelas, Sheyenne Lewis, & Briana Myers
Results
-27,194 studies met inclusion criteria -20 studies were used in the study -Participants included in the studies -Children with autism spectrum disorder (ASD) -Ages ranged from 2 to 14 y/o -Only level II-IV studies - Articles showed SIT intervention was effective for children with ASD.
The majority of the studies showed SIT to be effective in decreasing repetitive stereotypical movements, self-stimming, self-injurious behaviors, mood disturbances, problems with attention, while increasing sensory tolerance, self-regulation, and participation in occupations. However, further studies are needed with larger sample sizes, higher levels of evidence, and the use of standardized measures in order to strengthen the efficacy of SIT.
Title: Evaluating Different SI interventions on Challenging Behaviors and QoL in Children with Autism Abstract: This systematic review evaluates sensory treatment interventions (SIT) that address challenging behaviors and the quality of life of children with autism. Several databases were used to identify articles; 20 met the inclusion criteria and were analyzed in this study. Seven articles represented level II evidence; the rest were levels III and IV. The most common interventions were SIT combined with behavioral, exercise interventions, and craniospinal therapy which improved aspects such as sensory tolerance, self-regulation, and participation in occupations impacting children with autism’s quality of life. This poster presents the findings and discusses implications for occupational therapy practice with this population.

When outreaching to clients, African American participants felt more successful interacting with African American clients as opposed to other races/ethnicities, while White and Hispanic participants reported feeling equally successful with all races/ethnicities. It was found that there was a positive correlation between outreach and retention of specific races/ethnicities and between the ability to learn about clients’ cultural backgrounds and the ability to communicate with clients who hail from a different cultural background than that of participants.

Title: Student perceptions of learning about cultural diversity and ethnic minorities in their healthcare program. Abstract: Culturally competent healthcare professionals that address occupational injustices experienced by racial minorities are needed. While Gannon University offers events to address perceived health inequities, students are not required to participate. Consequently, students may not acquire the knowledge that guides them to become culturally competent healthcare providers. This study used the Cultural Competence Assessment to analyze healthcare students’ perspectives on their own cultural competence. This poster will present the results of this study and propose alternatives to decrease perceived bias and increase diversity and selfawareness in providing culturally sensitive assessments and interventions to racial minorities.

The Effects of Using aTask-Oriented Approach to Increase Upper Extremity Function in Post-Stroke Patients: A Systematic Review
Erin Bradley, Vanessa DeAnda, Amanda Martins, Sophia Zampardi
RESEARCH QUESTION
BACKGROUND I • Cerebrovascular accident, or stroke, is defined as a neurological deficit attributed by cell death from a lack of blood flow to the brain, depriving brain tissue of getting oxygen and nutrients. The interruption of blood flow to the brain leaves about 50% of post-stroke patients experiencing long-term effects. • Task-oriented approach: A top-down approach that emerged from a systems model of motor behavior and motor learning. This approach utilizes a client's everyday activities in order to find optimal movement patterns for task performance.
EFFECT ON BODY FUNCTION & ACTIVITY
In post stroke patients, what is the effect of using a task-oriented approach on upper extremity function compared to non-task-oriented interventions?
• Body function: functional and motor performance (UE), strength, sensation, motor recovery, coordination/speed, movement of impaired UE • Activity: Participation of ADLs and quality of life
CONCLUSION •
OUTCOME MEASURES • 36 primary and secondary outcome measures (20: body structure and body function and 16: ADL participation/quality of life/anxiety/depression • FMA used in 33.3% (8 studies)
METHODS
• •
Task-oriented approach showed improved body function and activities of daily living in post-stroke patients Effective on addressing meaningful activities Use for clients with appropriate cognition and desire to increase occupational performance
LEVELS OF EVIDENCE
• Inclusion criteria: acute stroke patients ages 55 or older, currently not participating in any other type of therapy, having R or L hemiparesis with onset due to stroke, medically stable to participate in therapy, and a score of 24 or higher on the Modified Mini Mental Scale • Exclusion: Moderate-to-severe cognitive impairment and articles not published in English • Key words: post-stroke, upper extremity, occupational therapy, rehabilitation, task- oriented approach, motor skills
DISCUSSION
Level 4 Evidence 17%
Level 1 Evidence 8%
Task-oriented training in the stroke population has the potential to: • Increase body function • Increase participation and engagement in ADLs
Level 3 Evidence 4%
• Increase quality of life • Improve overall rehabilitation outcomes
Level 2 Evidence 71%
Bilateral task training followed by unilateral task training of the upper extremities showed significant results and has potential to create long-term benefits in this population. This review demonstrated potential for task-oriented approaches to implement long-term benefits in stroke patients regarding improvements in quality of life and participation in ADLs.
Title: The Effects of Using a Task-Oriented Approach to Increase Upper Extremity Function in Post-Stroke Patients A Systematic Review Abstract: Our research question is aimed to investigate the benefits of task-oriented approaches on stroke recovery in occupational therapy practice. Our research question states the following: In post stroke patients, what is the effect of using a task-oriented approach on upper extremity function compared to non-task-oriented interventions? The study design was a systematic review that identified 721 articles. These articles involved people ages 18-85 and included 1,176. Some of the interventions involved included taskspecific training interventions, task-based mirror therapy, bilateral task training, and more. Overall, task-oriented approaches in stroke recovery patients have the potential to increase body functions, increase participation and engagement in ADLs, increase quality of life, and improve overall rehabilitation outcomes.

Teletherapy: Effectiveness in Aphasia Treatment
Rita Lenhardt, D.H.Sc., CCC-SLP
Introduction: Teletherapy is an increasingly prevalent treatment delivery method for speech therapy in general; therefore, it is important to evaluate its efficacy. This review explores the effectiveness of a restorative approach using teletherapy compared to a face-to-face delivery model with individuals who present with aphasia post-stroke. The outcome measures for aphasia treatment approaches, such as communication partner training, when administered via teletherapy were analyzed. Study results did not identify disparities in outcomes between face-to-face treatment and teletherapy deliveries.
Results:
Discussion:
• Results revealed that provision of aphasia treatment through teletherapy is beneficial for individuals. Teletherapy can improve patient access and it can help reduce the burden on our healthcare system. While this is a good stepping stone more research still needs to be done on teletherapy in the SpeechLanguage Pathology field. • Based on the research reviewed, two studies concentrated on the possibility of improvement of conversational speech and reduction of social isolation through the use of group therapy. Both studies found improvement in language abilities and reduction in impact aphasia plays in relationships/communication. • A study using virtual reality that lasted six-months proved that language rehabilitation had a significant positive impact on cognitive and psychological functioning. • In one study teletherapy and face-to face treatment both were successful with teletherapy having higher mean scores in some categories.
Based on these results, it can be concluded that teletherapy is not inferior to traditional face-to-face delivery in this specific population. Teletherapy as a delivery method is effective across a variety of intervention targets and techniques. Bilingualism and native language (our studies include Italian, Spanish, and English) do not appear to have an effect on teletherapy as a delivery method efficacy based on research. The option of teletherapy gave access to patients in rural areas who otherwise would have been unable to participate. The improvement participants made while receiving teletherapy, greatly outweighs the cost of teletherapy treatment according to findings. However, it should be noted participants in DeDe et al. (2019) were not able to maintain the initial progress when re-evaluated at six and eleven months post-therapy. Participants and caregivers received prior training in order to use the software and programs to access teletherapy, this training was instrumental to treatment.
Methods:
For this study, information was gathered using a scoping review of current literature after the year 2014, with a focus on comparison of deliveries. Specifically comparing face-to-face versus teletherapy delivery for adults suffering from aphasia. The research review excluded individuals with co-occurring medical conditions, and/or psychological conditions that could otherwise affect treatment outcomes.
Limitations: All studies consisted of small study populations. Group assignments were unable to be fully random and participants could not be blinded (meaning they knew what kind of therapy they were receiving). Other limitations included, group sizes within therapy sessions were often large, therefore, they are not individualized to each client as one-to-one therapy sessions.
Conclusion: As teletherapy becomes normalized, more research and studies will be conducted, which will help clinicians improve the telehealth as a whole. In the future, one hopes to see larger sample sizes for research studies. Telehealth is becoming more universal accepted as a service provision of the future of speech-language therapy.
(NoSystems, 2020)
• A study conducted by Jacobs et al. (2021) determined the cost of teletherapy was well worth the investment compared to how much participants improved. The average cost of teletherapy was $540-$1,296 for 5-12 sessions ranging from 45-65 minute a piece meaning each session cost about $108. The improvement monetary equivalency reached upward ($1,790.39-$3,912.54). • Studies conducted with Native Italian speakers and Spanish-English bilinguals addressed the question of the effect language or cultural background may have on the efficacy of teletherapy as a delivery method. Teletherapy proved to improve access to those in rural areas. • Patients whom were native Italian speakers, in both groups showed equal but significant gains in expressive and receptive language, functional communication skills & quality of life coping techniques. • The study with bilingual Spanish-English speakers focused on word retrieval showed no disparities between groups.

Discussion
Introduction Many people are aware of the impaired coordination, tremors, depression, and cognitive difficulties experienced by people with Parkinson’s disease (PD), but may not be aware of the speech, swallowing, intelligibility, and facial movement difficulties also associated with the disease. An estimated 70% to 90% of people with PD experience these difficulties, called hypokinetic dysarthria. Not only do these deficits impact the individual, but also the friends and family who interact with the individual and experience hindrances to communication as a result. One treatment, Lee Silverman Voice Treatment (LSVT) “has advanced speech treatment efficacy for patients with PD by addressing the complex etiology of the speech disorder.”4 LSVT is intensive treatment consisting of four, individual, 1-hr treatment sessions per week on consecutive days for four weeks (i.e., 16 sessions in 1 month) plus homework practice everyday during the month the client is in treatment. This systematic review of eight randomized controlled trials sought to determine the impact of LSVT vs. traditional speech therapy or vs. no therapy for hypokinetic dysarthria in people with PD. Study results indicate that patients who participated in LSVT showed a significant short-term improvement in their voice and speech quality.

These findings display the beneficial impact LSVT has in treating dysarthria in people with PD. Speech-language pathologists can use the findings to support their claims for using the LSVT approach on patients with dysarthria caused by PD. The eight studies analyzed support the idea that LSVT treatment is highly successful in treating patients with dysarthria caused by PD due to the following: ▪ Loudness increases, hypomimia decreases, psychosocial life is enhanced. ▪ Speech intelligibility and confidence in communication is improved. ▪ Improved quality of life for the patient and increased levels of happiness.

Suggestions for Future Research:
▪ Focus on using LSVT to target communication deficits in disorders other than PD. ▪ Encourage future studies to increase sample size & length of LSVT treatment. ▪ Study effects of LSVT on patients with PD at the conversational level, in natural environments.
Methods
▪ A systematic analysis was completed of eight randomized control trials to review the effectiveness of LSVT on voice intelligibility. ▪ Participants in the studies included adults with hypokinetic dysarthria secondary to PD between the ages of 45-85 years old. ▪ Articles were included if the patients had PD and hypokinetic dysarthria diagnosed by a neurologist. Articles were excluded if participants had a history of other speech and language difficulties and/or other concomitant neurological deficits such as stroke or traumatic brain injury (TBI). ▪ Each study used standardized measures or transcribed speech pre and post treatment to gauge patient and listener perceptions of speech and speech intelligibility. ▪ Three of the selected articles compared the outcomes of LSVT to groups of individuals who received delayed/no treatment. ▪ Four of the selected articles compared the outcomes of LSVT to groups of individuals who either had delayed/no treatment or were healthy. ▪ One article compared the impact of LSVT delivered in person to the impact of LSVT delivered via an online platform.
Results
▪ Improved intelligibility by listener ▪ Significant improvement in LSVT Loud vs. LSVT Artic group and untreated group ▪ Significant improvement LSVT Loud and LSVT Artic groups vs. untreated group ▪ Significant increase in loudness measures post LSVT ▪ Improvement in Voice Handicap Index scores in LSVT group vs. untreated group ▪ Significant improvement in intelligibility at word and sentence level, in background noise, and in prosody ▪ Increase in frequency and range of spontaneous facial expressions ▪ No difference at 12 mos. but differences at 3 mos. between LSVT, Speech Language Therapy group vs. untreated group to be confirmed in main trial ▪ Significant improvement in quality of life and acoustic perceptual measures

Introduction
● Overall, patients scores have improved since the start of the experiment. ● Significant improvement from baseline to post-intervention in cognition was reported. ● The improvement in cognition may be attributed to the effect of exercise on the brain cells which decreases beta-amyloid proteins leading to decreased amyloid plaque, neural disruption, hence improving brain health. ● Exercise program provided by the Community Health Center and reading aloud activity had positive effect on the cognitive function of older people with dementia.
● Dementia is a condition occurring in older adults that results in a loss of cognitive function such as memory loss, language skills, problem solving and decision making. ● Cognitive treatment is used to improve quality of life and slow progression of symptoms. ● Can Compensatory strategies involving mental stimulation prolong their cognitive function to communicate effectively?

Methods
● Three randomized control studies and cognitive training ● Using the stimulation program (Theory of Mind), twice a week for forty minute sessions for five months ● Twelve week progressive task-oriented circuit training ● Quasi-experimental, with a two -group, pretest-posttest research design ● Samples were collected from pre/post test using the Alzheimer's Disease Assessment Scale, Mini Mental State Examination-Thai version 2002, Basic Activities of Daily Living, Chula Activity of Daily Living Index, Neuropsychiatric Inventory Questionnaire, and the Zarit Burden Interview ● Participants were recruited based on having a diagnosis of dementia as well as meeting inclusion criteria. ● Experimental groups who received treatment showed better results as opposed to control groups who did not.
Discussion
● Study determined the efficacy of progressive task-oriented circuit training on cognition, physical functioning, and societal participation in individuals with dementia. ● Participants in both groups were homogenous as they were similar in age, duration of diagnosis of dementia and endurance capacity at baseline. ● The combination of fitness activities and reading aloud conducted by professional healthcare personnel enhanced not just cognitive function in older adults with dementia, but also their capacity to participate in physical activity.
Conclusion
● Compensatory strategies used to improve cognitive function benefited MOST participants’ overall quality of life as their dementia progressed. ● Progressive Task-oriented Circuit Training is more efficacious in enhancing and developing therapeutic strategies to train cognition and improve functional performance and societal participation in the rehabilitation of individuals with dementia ● Several factors may be involved in the linguistic performance of people with dementia ● The evolution of each patient presents a multifactorial etiology, and it was influenced by different variables related to the patients and their psychosocial environment ● Implementing the reading aloud and Indonesian older people exercise program together led a to a significant improvement in the cognitive function of older people with dementia.
Limitations ● Duration of the programs ● Selection bias ● Severity of Dementia

Title: Effects of Compensatory Strategies used in Treatment with Dementia Patients Abstract: Dementia is a condition primarily occurring in older adults and results in a loss of cognitive functions, such as impairments in memory, language, thinking, and judgment. Cognitive-communication treatment is utilized to improve quality of life and slow progression of symptoms. Individuals learn compensatory strategies and participate in mental stimulation exercises to maintain functional communication abilities. Review of evidence indicates that experimental groups who received compensatory strategy treatment showed better results compared to control groups. Therefore, treatment approaches involving compensatory strategies help improve cognitive functions and benefit participants by enhancing their overall quality of life as their Dementia progresses.

Conclusion In conclusion, this project began with gathering information regarding the educational state requirements of a variety of health professions. Next, a review of the complaints filed against health professionals at the state level was completed. It was discovered that there are a variety of organizations that regulate educational requirements, board examinations, individual professions, including state and national requirements. Ongoing continuing education differs among the professions. All health professions have interprofessional accreditation standards dictating that IPE is part of each profession's formal education. This review has led to multiple questions and directions for future research.
Future Research • Is there a correlation between education/continuing education requirements and complaints against health professionals? • Who is making the complaints? Patients or other health care professionals? • What are the academic accreditation requirements within each profession regarding ‘Ethical Practice’ and ‘Interprofessional Education’? • Are academic programs following best practice in IPE education, for example the ‘IPE Collaborative Competencies’?

Title: An interprofessional review of the relationships between educational requirements among licensed health care professionals in the state of Florida and past decade of complaints filed Abstract: In 2020-2021, the State of Florida had over 100 complaints filed against licensed health care professionals in the fields of athletic training, occupational therapy, physical therapy, physician assistant, and speech-language pathology. Over 20 of those were legally sufficient, indicating that if complaints were true, potential Florida Statues or Rule violations occurred. Using a conceptual analysis approach, this poster will disseminate relationships between interprofessional education requirements, required continuing education units, and complaints filed in the State of Florida over the past ten years. Future research direction will investigate educational IPE compliance, complaint numbers and reporting across disciplines.

The Importance of Identifying Early Cognitive Change and Conducting Equitable Studies with the Inclusion of Older Adult Minorities Introduction:
Older adults fear the development of neurodegenerative diseases such as mild cognitive impairment (MCI) or dementia such as Alzheimer’s disease (AD; Kelley, McGarry, Gorges, & Skinner, 2015, Morris et. al., 2001). MCI and AD pose a threat to the health, quality of life, and independence in daily function of older adults. Preliminary findings indicate that older adults experience early changes in communication and memory and other areas of cognition prior to diagnosis. Therefore, identifying early cognitive changes can lead to new prevention protocols that can minimize the negative impacts and delay the onset of dementia such as AD. Additionally, obtaining a representative sample would help to generalize findings and make more accurate clinical recommendations regarding the implementation of early assessment tools and protocols.
Purpose of Study:
-AIM 1: Identify effective assessment approaches aimed at early detection of cognitive impairment in older adults -AIM 2: Establish fundamental knowledge regarding the inclusion of minority populations in research to gather a representative sample of the older adult (60+) community.
Hypothesis: We predict that analysis of data will demonstrate statistical significance in identifying early cognitive-linguistic indicators that are correlated to cognitive performance and show group differences among persons with and without MCI. We also predict that the sample collected thus far is uniform and lacks diversity. Results: Aim 1: •
•
Preliminary analysis (n= 27) of 98 linguistic features pulled from the samples found that only nine linguistic features (see Table 3) were useful in identifying cognitive performance and demonstrated medium-strong correlations of ≥ .45 to MoCA scores. Univariate ANOVA results of seven dependent variables demonstrated significant group differences based on cognitive status (i.e., MCI vs Non-MCI). Preliminary analysis (n= 27) indicated that of the three speech-language tasks, the free conversation task and the story narration-wordless picture book task were optimal in eliciting the nine linguistic features with potential for differentiating cognitive status (i.e., MCI vs Non-MCI) when compared to the picture description task.
•
•
Results indicated a uniform sample that lacks diversity, specifically of minority groups. When combined with the larger study (n= 52), the participants identified as follows: 44 of them where White, 4 were Black, 2 were Hispanic/Latino, 1 Bi-racial, and 1 identified as Other. Overall, the study enrolled more female (n=33) than male (n=19) participants. As a result of the preliminary analysis, recruitment methods were implemented to improve enrollment of a more diverse sample. Analysis of the current sample (n= 25). Various methods of recruitment were utilized in addition to the original recruitment method (i.e., telephone list of participants from previous studies). The new methods included distribution of flyers in community locations and social media platforms, research volunteer websites, referred by a friend, referred by faculty member, paper mail, newspaper, and telephone lists from attendance to health fairs and community talks. Overall, the top three means of recruitment methods were receiving a phone call, volunteer website, and previous research. However, the top means of recruitment for minority participants was family/friends, mail, and receiving a phone call.

The study is a collaboration between the University of South Florida (USF) and Gannon University (GU). It is a five-year longitudinal study of cognition investigating several potential predictors of cognitive change among healthy older adults (i.e., 60 + years of age).
We have enrolled 52 participants across both USF and Gannon sites. These included 27 enrolled in the pilot study and 25 enrolled thus far in the current study. The demographics of the 52 participants in terms of age, education level, and gender are depicted below in Table 1. For information regarding race and ethnicity see Figure 1.

Procedures
Preliminary pilot demographic and speech-language data were extracted and analyzed from a larger study (n=27). Additional participants (n=27) were recruited using varied recruitment methods. After meeting initial inclusion/exclusion criteria, participants were consented, and demographic data was collected through a study visit questionnaire. Participants were administered a cognitive measure. Participants were given three speech-language sample prompts which were recorded using audio equipment and computer software. Demographic and Speech-language data was extracted and analyzed.

Discussion:
Based on the preliminary data, this study supports the hypothesis and concludes that the analysis of linguistic features demonstrated statistical significance in identifying cognitive performance and cognitive status (i.e., MCI vs Non-MCI). The sample size was small and lacked diversity which supports previous studies that mention the lack of diversity across research in general. However, recruitment and data collection are ongoing. It should be noted that this study has been an ongoing investigation throughout the global pandemic; COVID-19 health concerns could have impacted willingness to participate, especially for minorities who were at greater risk of contracting COVID-19. The findings of the study provide valuable guiding information about key cognitive-linguistic features that have potential for differentiating cognitive status in MCI populations and can be used as early indicators since MCI is a known risk factor for AD. Additionally, it provides valuable information for researchers working to obtain a diversified and representative sample. If not, irrefutable consequences can follow as stated by Palmer and Burchard, “this includes impeding our ability to generalize study results, make medical advancements of effective therapies, and it prevents some populations from experiencing the benefits of research innovations and receipt of high-quality care.”

Title: What factors affect student’s communication with their support systems and what influence does this have on their mental health and academic success? Abstract: University students may be challenged with obstacles that impact their academic performance, relationships, and ultimately, their mental health The purpose of this study was to identify if and how students communicate with their support systems regarding these obstacles and how this communication impacts the student’s mental health. A survey was developed and delivered electronically to students attending 5 Universities. The survey asked students about their preferred communication method, how often communications occurred, and how it impacted the student’s mental health. This poster will present findings from this survey, including how communicating with support systems impacts student’s mental health.

Music as a Modality in Occupational Therapy Introduction Occupational therapy encourages rehabilitation through the performance of activities essential to daily function to treat individuals with physical or mental impairments. The development of stress coping skills is an aspect of functional health management. The ability to manage this biological response to one’s environment is critical to maintain one’s physical and mental health. Music has been shown in general to be a stress reliever, and this study looks to investigate how the modality of music applied before stressful events, if it will decreased stress. Our research aims to look at if the high stress environment of graduate school creates the need for mental health management through regulating emotion and reducing elevated stress levels with music.

Results
Research question How does making music versus listening to music effect the occupation of health management in graduate students? Inclusion •First year students in Gannon University's Occupational Therapy Doctorate program
Exclusion •Students over 31 years old •Students with a severe mental health diagnosis •Students that are professionally trained in the instrument provided Methods 28 students were offered participation in the study and 17 students that filled out the informed consent forms participated. The intervention was about 45 minutes before their student’s lab practical. Participants were randomly assigned to one of three groups (Music Playing, Music Listening, and Control). They all filled out a questionnaire that detailed stress levels prior to the intervention. The Music Playing group had their pick of instruments (piano, guitar, ukulele, drum, cowbell, and maracas) to play for 15 minutes by themselves in a room. The Music Listening group received the same amount of time to listen to their preferred music alone in a room using headphones on either their own music playing device (i.e. smartphone, mp3 player, iPod, etc.) or on the iPad that was provided. The control group sat in silence for 15 minutes in a room by themselves. After 15 minutes, the participants filled out the post-test questionnaire assessing their stress levels post intervention.. Once completed, they were dismissed to take their practical examination.
Discussion Our results yielded that music playing and listening did not have a significant effect on stress levels and the overall health management of students. A one-way ANOVA shows the statistical results of the experiment. The pretest groups were not significantly different at the beginning: F(2,14) = .857, p = .446. They also were not significantly different at the posttest: F(2,14) = .624, p = .550. So, the type of treatment (music 2 ways or nothing) made no difference in our study. Since there were no differences between the groups, there are no further statistics that are indicated.
Conclusion Based on the results and discussion, the answer to our research question is that making music and listening to music do not have a significant effect on the sample of occupational therapy graduate students. The sample size should be larger in replicated studies down the line. Future studies should investigate music's implication on everyday life for students, as well as potentially using different outcome measures that represent stress and anxiety more accurately.

Title: Music as a Modality in Occupational Therapy Abstract: Our research question is aimed to understand the therapeutic benefit of music on stress levels and mental health management in occupational therapy practice. The current study strives to investigate the research question of “How does music-based intervention, both making and listening, effect the occupation of health management in graduate students?” This true experimental research design involves looking at how graduate students’ stress levels are impacted with musical intervention prior to a practical. It was expected that there would be a difference in stress levels between students who receive a music-based intervention versus those who did not, due to COVID-19, the study was delayed.

Title: A Literature Review Effectiveness of Aphasia Support Groups In-person versus Online Abstract: COVID-19 has made an impact in the practice of Speech-Language Pathology. With the rise of cases, teletherapy and digital health became an alternative for clients in 2020, and is still utilized in many therapy settings. The purpose of this paper is to provide a literature review of the literature on comparing and determining if there is a difference in the effectiveness of support groups inperson vs. online platforms for individuals with aphasia. Support groups are very important for individuals with aphasia, as it provides psychosocial benefits, as well as positive health benefits of building interpersonal relationships and community (Elman, R. J. (2007). Elman, R. J. (2007). The Importance of Aphasia Group Treatment for Rebuilding Community and Health.

Investigation of the Effects of Smartphone Use on Wrist Pain in Graduate Students
Faculty Advisor: Dr. Bonnie Decker
Abstract:
Methods:
Results:
The purpose of this research was to examine if smartphones effect wrist pain in graduate students using a one-group pretest-posttest experimental design. Each subject typed a script from the movie ʻSheʼs the Manʼ on their smartphone for 10 minutes. Pictures were taken of their arm(s)/hand(s) position while completing this activity. Subjects completed a pain scale rating pre and post-activity. Additional data regarding use of their smartphone and frequency of pain were also recorded. The results of this study showed that participants pain from pre-test to posttest significantly changed.
Subjects: Subjects were gathered from a convenience sample of students. A total of 50 subjects participated in this study. There were three inclusionary criteria for this study. Subjects were required to utilize a smartphone for at least one hour a day, have no prior surgery on the upper extremity, and have no musculoskeletal or neurological diagnosis affecting the upper extremity. • Average age: 25.6 years old • Gender: Females n=45; Males n=5 • Program: 40 OTD, 9 DPT, 1 SLP
The Wilcoxon Signed Ranks Test compared the NPRS pre-test scores to the post-test scores for all 50 subjects. The test statistics were z—5.558, p<.001 this demonstrates a significant different pre and post for all subjects. Significant correlations were found between the NPRS post-test scores and the survey question, ‘I have pain in either my left or right hand or wrist while texting/typing on my smartphone’ (r= .325, p<.05) and between NPRS post-test scores and the survey question, ‘pain level during extended periods of texting/typing on a smartphone’ (r=.291, p<.05).
Introduction: Graduate students utilize their mobile phones continuously throughout the day. Research found that graduate students spent 143 minutes on average using mobile phones and many postures caused concern for musculoskeletal imbalances (Short et al., 2020). The purpose of this research was to examine if smartphones effect wrist pain in graduate students.
Outcome Measure: Pain in the wrist/hand during typing was measured using the Numeric Pain Rating Scale (NPRS). Typing: Subjects continuously typed on their smartphones for 10 minutes. The total length of the study was about 15 minutes for each subject.
Discussion: This study demonstrated that subjects perceived pain did change from pre-test to post-test scores. Gender, program, and age did not show significant findings demonstrating that all individuals perceived pain changed from pre-test to post-test. Additional research should examine pain and sensation testing to determine if there is a relationship between extended periods of texting/typing and neuropathies. References:

Youth Competitive Swimming and the Benefits of Weightlifting and Resistance Training Detria Smith, MSES, Ruskin, FL
Methods Abstract The purpose of this study is to address weightlifting and resistance training’s risks for competitive swimmers and explain why it is ultimately a beneficial and integral part of their pre-, mid-, and post-competition training. The study will consist of 103 youth competitive swimmers split into 5 groups based on swim experience. Those involved in weightlifting with dumbbells, barbells, and heavier equipment are a part of the older swimming groups (Senior, Senior Prep, and Gold). Those involved in lighter equipment (resistance bands and body weight) are a part of the younger swimming groups (Silver and Bronze). Changes in exercise performance will be assessed through observations in exercise performance by the swimmers via rate of perceived exertion (RPE) in the weight room, by their coaches via personal record (PR) times in practice, and by participation in exercise tests, i.e., the pull-up test. This study will take place over a 4-week exercise regimen. It is expected that the older swimming groups (Senior, Senior Prep, and Gold) will see increased speed and power in the water, and the younger swimming groups will see improved balance, coordination, and form.
Background
❑ Participants ❑ The participants will include 103 students between the ages of 6 and 18 who attend the New Tampa Family YMCA located in Tampa Palms, FL. ❑ Exclusion criteria are being younger than five or older than nineteen, having any back injuries, or difficulties with range of motion in their limbs or joints. ❑ Set-Up and Design ❑ Each group has a land-only intervention, followed by their normal aquatic practice. ❑ Upper body assessment includes a pull-up or modified pull-up test. ❑ All tests will be performed in the outdoor workout center located behind the pool beside the weightlifting gymnasium. ❑ Procedure ❑ 4-6 week exercise intervention with muscular strength and endurance focuses ❑ 4 groups per day consisting of “weights only” (Senior and Senior Prep), “resistance band only” (Silver), “resistance band to weight progression” (Gold), and “bodyweight-only” (Bronze) with one 20 minute session per group. ❑ All experimental groups have the same warm-up phase for 10 minutes with dynamic stretches and the same cool-down phase for 10 minutes of static stretches ❑ To cover the entire body, a full range of exercises will be conducted during the week that coincides with the normal range of motion experienced while swimming. Each group will perform upper body work on Mondays, Lower bodywork on Wednesdays, and Core/Back work on Fridays. Each exercise will involve a heavy emphasis on pulling motions, squatting, and should and core stability and strengthening. Pull Based Weight Exercises Resistance Band Exercises
❑Adolescent weightlifters displayed levels of bone mineral density and bone mineral content well above values of age-matched controls (1). ❑6 weeks of complementary dry-land S&C training may lead to improvements in dry-land strength. Furthermore, a 4-week adaptation period was mandatory to achieve beneficial transfer for aquatic performance (2). ❑Plyometric training has been demonstrated to improve endurance in vertical jumping, leg strength and acceleration (3)
Expected Results Conclusions ❑ It is expected both “weights only” and “resistance band to weight progression” groups will experience significant gains in muscular strength. ❑ It is expected that both the “resistance band only” and “bodyweight-only” groups will experience significant improvements in core strength, coordination, and stability but minimal improvements in muscular strength. ❑ It is expected that the older swimming groups (Senior, Senior Prep, and Gold) will see increased speed and power in the water, and the younger swimming groups will see improved balance, coordination, and form.

Gaps ❑The main issue with the following data involves the number of days per week the subjects will be participating in the study. Instead of 5 days per week, the subjects will participate three days per week in order to fit within our respective schedules. This may impact their results.
Pull Up Test
❑Another issue is attendance. Attendance is not required for the participants, which results in some students coming to the program once or twice per week. This may impact results. ❑The youth swimmers ages may have an impact on their results. The swimmers participating range between pre-pubescent and 18 years old. Hormone development or lack thereof may impact the gains from strength conditioning.
Purpose ❑The purpose of this study is to address weightlifting and resistance training’s risks for competitive swimmers and explain why it is ultimately a beneficial and integral part of their pre-, mid-, and post-competition training.

The Relationship Between Social Support Systems and Graduate Student Stress Levels Emili Alexander, OTDS,MS, Carrie Fromm, OTDS, Vanessa GalindoJackson, OTDS, Anna Ingram, OTDS, Briana Myers, OTDS Bonnie Decker, OTR/L BACKGROUND • Graduate students are 6x more likely to experience anxiety and stress. • Primary sources of social support (SS) include; friends, family, and faculty. • 75% of students report elevated stress levels due to leaving their social support system. Social Identity Theory • Social categorization, identification, and comparison occurs naturally within groups causing division. Once two groups identify themselves as rivals' hostility sets in and they are forced to compete for resources (e.g., fighting for school services, faculty attention, equipment, etc.). Stress Buffer Hypothesis • Strong social ties act as protective barriers against stress, improving an individual's well-being. Those with limited social ties are more susceptible to the negative impact of stressful events

We created a mixed methods survey and administered it to full time graduate students at Gannon University. The questions investigated the stress a student experiences when leaving their support systems to attend graduate school. Once survey data was collected and analyzed, we found that our research supported a positive correlation between graduate student stress and leaving their support systems. This poster describes this study’s findings and how it will contribute to the greater body of literature regarding the transition to graduate school.
