From the Editor
The 3D revolution in printing technology is set to change the way we manufacture products. But an equally compelling reason for welcoming the 3D boom is its impact on student learning. In this issue of CityU Today, we will examine how rapid prototyping enhances the educational experience of our students. Several faculty members and our technical support team offer their views. It is not just technology, though, that empowers students in learning. Dr Elaine Au of the Department of Applied Social Sciences talks about her UGC teaching award and her commitment to encouraging students to work for the betterment of society through volunteering. In addition, a brand new column focuses on our supporters and donors in the community, men and women who contribute so much to CityU’s development, and we will find out more about our new Dean of the School of Law and his take on legal studies in Hong Kong and further afield. Happy reading!

Virtual reality for virtuoso learning
By Cathy Lau
文：劉靜萍
An innovative virtual reality (VR) programme developed by researchers at CityU is being used to help severely intellectually disabled (SID) students overcome learning challenges. This VR programme, funded by the Quality Education Fund (QEF), helps to strengthen pre-learning abilities and promote self-awareness through learning scenarios that focus on repeated training. The programme, called “Interactive Sensory Programme for Affective Learning” (InSPAL), also decreases behavioural tendencies that can often interfere with learning and social interaction, according to Professor Horace Ip Ho-shing of CityU.

To improve current infrared detection systems, Dr Lai is developing a highly sensitive graphene-based infrared detection chip. If an infrared signal is illuminated on the chip, the device will absorb the infrared photons and then release electrons to generate photocurrent. The voltage signals transformed from the current will be converted to warning signals or recovery images by other technologies. “Our target is to develop a system that can detect infrared signals emitted by different objects at a distance of around 100 metres. Based on an analysis of the wavelength for determining the obstacle ahead, the system will automatically issue a warning signal,” Dr Lai said. “Street lights aid drivers in the evening, but this may not be the case for drivers in the US and Europe where drivers often rely on vehicle headlights outside of urban areas, which can lead to a dangerous situation if an animal is on the road.

Infrared Infrared is an invisible energy but it is perceivable. The heat that we feel from sunlight, fire or heaters is a kind of infrared. The primary source of infrared is heat and thermal radiation produced by the motion of atoms and molecules in an object. The higher the temperature, the more the atoms and molecules move, and the more infrared radiation they produce. Any object that has a temperature above absolute zero (-273.15˚C) radiates infrared. Hence, many objects around us emit different infrared wavelengths and intensities. Although infrared is not visible to the human eye, scientists have invented mechanical eyes that can detect it for us: an infrared camera. The same as an ordinary camera that makes use of light to produce images, an infrared camera detects infrared emitted by objects and then generates images. The spectrum of infrared is divided into three sections by wavelengths: near-infrared has a wavelength of 0.75-3 micrometres, mid-infrared 3-8 micrometres, and far-infrared 8-15 micrometres. The wavelength of infrared radiation emitted by humans at normal body temperature is around 12 micrometres.

新型紅外線探測器—道路安全新法寳 全世界每年發生的汽車交通意外，造成大量人身傷亡和經濟 損失。 城大一位專家正主導一個項目，研發汽車用的石墨烯基光譜紅外線 探測器，以增進道路安全，防止交通意外。 這位專家就是機械及生物醫學工程學系助理教授賴偉超博士，他 說：「用石墨烯為探測元件的紅外線探測器即使在室溫下也有很高 的靈敏度，不單能增強駕駛者晚間的視覺，還可在惡劣天氣下探測 到車輛前方的障礙物究竟是路燈、人，還是動物。」 石墨烯是由碳原子組成的一種特殊結構，是目前已知最堅硬、最薄 的納米材料之一，在室溫下導電、導熱能力極強。這些優異的性能 使它成為紅外線成像系統核心部件的理想材料。 現在，一些新款頂級汽車已安裝了紅外線攝影機，探測近紅外線或 遠紅外線。不過，目前這些系統各有不同的技術局限。 近紅外線探測攝影機發射紅外線，如前方有障礙物，紅外線會反射 而觸發警報。然而，在大雨或大雪中也許會發生誤報。此外，近紅 外線探測系統無法探測到人體發出的中紅外線或遠紅外線。 中、遠紅外線探測系統的運作方式不同，工作溫度一旦高於攝氏零

紅外線 紅外線是一種肉眼看不見、但感覺得到的能量。陽光、火、暖爐發出的熱，就屬於紅外線。 紅外線主要來自物體中原子和分子運動時所產生的熱和熱輻射。溫度愈高，原子和分子的運動便 愈劇烈，產生的紅外線輻射也愈多。所有本身溫度高於絕對零度（即攝氏零下273.15度）的物體都 會發出紅外線，故此我們周圍有很多東西可以發出不同波長和強度的紅外線。 人的眼睛雖然無法看到紅外線，但科學家早已發明可探測紅外線的機械眼睛─紅外線攝影機。這 種攝影機能探測物體發出的紅外線，形成圖像，一如普通攝影機利用光線成像一樣。 紅外線的光譜依據波長大致可分為三個區段：近紅外線的波長是0.75至3微米；中紅外線的波長是 3至8微米；遠紅外線的波長是8至15微米。人體在正常體溫下所發出的紅外線波長大約是12微米。

Among all Hong Kong Diploma of Secondary Education (DSE) students admitted to CityU in 2013/14, LLB had the highest average DSE scores, taking into account the results of 4 core subjects and 2 electives, and the highest average English score among all newly admitted students.

A core belief in CityU’s curriculum is the need to integrate teaching and research, and the School of Law is an exemplar of how that is possible. The application of law and case studies to new problems in the quest to find resolutions is the foundation of legal education. “We will continue to enhance our strengths and offer our students the best possible legal education through our traditional strengths in Chinese law and enhanced offerings in commercial, private law and arbitration,”

此外，一些涉及重大法律問題的大型會議在這裏舉行，也使法律學 院有機會直接參與一些有影響的事務。 例如，今年2月，法律學院屬下的「中國法與比較法研究中心」籌辦 了關於2017年行政長官選舉第二輪諮詢的圓桌會議，使本港的憲 法學者得以聚首一堂，討論多項有關議題：提名委員會的構成及產 生辦法、提名行政長官候選人的程序、行政長官選舉的投票程序等 等。 專業訓練 在學生所受訓練之中，仲裁與調解仍將是不可缺少的一部分，其中 一項重要活動是在城大舉行的「國際替代性爭議解決機制模擬法庭 比賽」，參與籌辦這項比賽的合作機構是中國國際經濟貿易仲裁委 員會、美國哥倫比亞大學、聯合國國際貿易法委員會亞洲及太平洋 區域中心。 第六屆「國際替代性爭議解決機制模擬法庭比賽」訂於2015年8月 在城大舉行。去年，這項比賽吸引了全球各地24支隊伍參加，包括 澳洲、中國內地、香港、印度、馬來西亞、巴基斯坦、波蘭、新加 坡、斯洛文尼亞、韓國、台灣、英國等。

Howells教授解釋說，「調解」是自願解決紛爭的程序，由調解人設 法幫助各方自行解決紛爭，而「仲裁」的解決辦法，則是由中立者 作出某一方勝訴的裁決。
法學世界的探索與創新 Howells教授還說，為了配合城大的「重探索求創新課程」，法律 學院將會對學生反覆強調探索與創新的迫切性。
Howells教授的學術研究興趣包括消費者法、產品責任、歐洲私 法、電子商務等專題。他說：「城大法律學院在模擬法庭競賽中屢 創佳績，如今已聞名國際。」城大代表隊曾在2014年3月舉行的菲 立斯國際法模擬法庭辯論賽之香港分區賽中連續第二年奪冠；此 前亦在其他重要的模擬法庭競賽中獲勝，如2013年第20屆維斯國 際商事仲裁模擬法庭辯論賽，並在2012年參加該項比賽的香港姊 妹賽事—第九屆維斯（東方）國際商事仲裁模擬法庭辯論賽中奪得 冠軍。
學院的本科生必須做好準備，以應付多方面的複雜問題，包括香 港基本法、憲法問題、交易模式的變化、戰爭及衝突、種族滅 絕、協助自殺等，以及惹人爭議的問題，如煙草等領域，而煙草 問題是消費者保障法例中的一大要點，亦是Howells教授所專長 的一個領域。
Howells教授說：「這些成績都很了不起，但重要的不僅是獲獎。 學生在準備和參賽期間獲得極寶貴的經驗，並學到許多技能；畢 業後進入就業市場，這些技能能給他們帶來極大的優勢。」 優質生源 法律學院開設多個學位課程，包括法律學學士課程、法律博士課 程、仲裁及爭議解決學法學碩士課程、法學碩士課程、最後由中國 人民大學頒授學位的法學碩士課程、香港法律深造文憑，還有多 種研究式學位課程；有意報讀者的競爭十分激烈，因此學院的學 生都是城大校園內的佼佼者。 2013-2014學年，修讀法律學學士課程的新生的中學文憑試六科 （包括四個主科及兩個選修科）平均成績，在城大新生中屬於最 高，其英文科平均成績也最高。2014-2015學年，法律學院錄取的 新生的中學文憑試六科平均成績，同樣在城大全校新生之中屬於 最高。
「煙草是一個涉及法律、道德、公眾健康等各個方面的複雜問 題，似乎人人都有自己的見解，」Howells教授說。他的專著 《煙草的挑戰：法律政策與消費者保障》（2011）探討為何必須 控制煙草消費，並立例規管。 未來發展的方向 「教研合一」是城大課程的核心理念，而法律學院正是實踐這個 理念的模範。學院的法學教育，乃建基於將法律與案例研究運用 於當前的新問題，以求得解決方法。 Howells教授說：「我們將繼續提升中國法方面的傳統優勢，同 時改進商業法、私法、仲裁等領域的課程，由此增強本學院的實 力，為學生提供最好的法學教育。」 「學院鼓勵學生在學習過程中積極參與社會，努力探索、創新。 說到底，這個世界就是律師的實驗室。」

The principle of whole-person development 全人教育 持之以恆 By Dr Elaine Au Liu Suk-ching Associate Professor and Assistant Head of the Department of Applied Social Sciences
文：區廖淑貞博士 應用社會科學系副教授兼助理系主任
Born in a poor family, I had no particular aspirations for my future when I was a child. All I knew was to study hard and find a good job upon graduation. I wished to be an office clerk when I was in junior secondary school. Later when I studied in high school, my dream career was “upgraded” to a secretary. Unintentionally, I became a social worker upon graduation. I joined CityU as a faculty member after being a social worker for 10 years. Another 12 years passed, and I was appointed as the Residence Master of Jockey Club Humanity Hall (a student residence in the first phase). Living with students from various disciplines, I found my previous social work experience particularly useful. At some point I was even inspired to develop the City-Youth Empowerment Project (CYE Project) that aims to encourage students to do voluntary work and build up their confidence. Last year, I was one of the three recipients of the Award for Teaching Excellence from the University Grants Committee (UGC). That year also marked the 10th anniversary of the CYE Project that has developed from an initial enrollment of some 100 participants to more than 1,000 now. My social work experience has had a significant influence on me, making me realise that a social worker serves the role of a companion, accompanying those seeking help, caring about them and helping them rebuild their confidence so that they can move forward. For many students, university hall life means living with a large group of people away from home for the first time, which takes time to get used to. Therefore, for some minor behaviour problems, I do not resort to disciplinary actions. Rather, I wish to encourage students to do meaningful things and cultivate their sense of belonging to society. This is exactly my original idea of setting up the CYE Project.

Many young people appear to be very assertive, but deep down they are not sure about themselves. They need moral support and someone trustworthy to give them that extra push. Therefore, for both hall activities and the CYE Project, I ensure that students know clearly about their plans. Then I let them take charge of the activities so they can build up their confidence and a greater sense of responsibility. Humanity Hall has eight Year 3 or Year 4 students serving as residence tutors who take care of all matters and lead all 341 students of the Hall. Sometimes the young leaders are hesitant and I tell them, “All eight of you are university students; you are better qualified than the management

不少年輕人看似衝勁十足，其實內心欠缺自信，需要精神支持，需 要一個他們信任的人給予額外的推動。因此，不論是舍堂事務或優 權計劃，我都會確保學生完全明白每個計劃，然後放手讓學生負責 各項活動，以培養他們的自信和加強他們的責任感。
有許多義務工作項目成效不彰，無疾而終，是因為參與者得不到 有效的指引。曾聽一個年輕人說，他服務的機構在他的上級離職 後再沒有聯絡他，他感到自己的服務再也不為人所需，又太靦 腆，不敢主動聯絡對方，結果退出了義務工作。這很可惜。
敬賢堂的架構是由八名三、四年級的學生擔任導師，負責舍堂的大 小事務，領導341名宿生。有時學生導師猶豫不決，我會勉勵他們 說：「你們八個大學生，加起來已勝過很多公司的管理層了，怎麽 會有做不到的事？」但下放權力不等於放任不管，我會做學生的後 盾，與他們分憂。
打從城青優權計劃推出的第一天起，我便盡力使所有參與的學生 都有全職同事支援。我的方針是建立起義工與機構之間的長遠關 係，幫助義工建立自信，掌握領導才能，培養正確價值觀。
我與學生開會，不是在會議室，不是在辦公室，而是在我家的飯 廳。我堅持用住家飯招待學生，每次飯局前都與丈夫一同計劃、準 備、搜羅好食材，有20到30個學生前來吃飯是等閒事，最多一次 有70人之多！敬賢堂的理念、文化，城青優權計劃的成立過程、經 驗，培養領袖感染力的秘訣，都是在飯桌上宣揚、傳授的。 連我兒子也說：「你的學生真幸運，我就從來沒遇見過一個跟你一 樣對待學生的教授！」
我的教育生涯是由執教「社會工作導讀」課開始的，自此便深明自 己肩負啟發學生的重任。當城市理工升格為大學時，我一邊攻讀 博士課程，一邊教學、做研究、寫論文，絕不輕鬆，而那時兒子 才幾歲大。未幾更接受任命，出任舍監，為所有學生創立了優權 計劃。我從不視困難為畏途，從不介意多做一些。我想，就是這 份熱切的人生態度，感染著學生投入義務工作，貢獻社會。
「我的座右銘是寧可吃虧一點也要遠離爭端。 這樣省下了很多時間。」
城青優權計劃不計學分、沒有獎賞，儘管如此，它在十年間茁壯成 長，吸引了逾800個學生投入定期的義務工作，曾合作的機構多達 30個，甚至在尼泊爾、緬甸、柬埔寨建立了「接觸點」。透過接觸 點，學生得以實際應用專業知識，與當地人一起致力於社區發展。 城青優權計劃由敬賢堂開始，現已擴展至其他舍堂和非住校生，甚 至有不少學生畢業後繼續參加─誰說這一代年輕人不願付出、只 懂抱怨？

Starting from this issue, CityU Today will carry interviews with members of the Foundation, one person at a time, who will share their life stories and talk about how they became associated with the University and its developments. 「香港城市大學基金」於2014年成立， 旨在為社會賢達和關心城大發展的朋友 搭建平台，共同為香港教育和城大發展 作出貢獻。《今日城大》每期將訪問一 位城大基金會員，邀請他們分享人生故 事，以及與城大結緣的點滴。
Doing ordinary deeds well Mr Chan Hon-pun first came into contact with CityU in 2007 when attending a forum hosted by the University as a member of the Buddha’s Light International Association of Hong Kong (BLIA), and later in 2014 when attending a seminar at CityU about age-friendly communities, representing the Rotary Club of Shatin. “I can feel the ceaseless efforts CityU has made all these years, and its progress and developments are obvious to all,” he said. “I converted to Buddhism in 1990 under the inspiration of Venerable Master Hsing Yun,” he recalled. “Then, seeing the great need for well-educated people for the future of society, I decided to do some good by contributing to education, though I knew there wouldn’t be immediate results.” He chose to help CityU, thinking his donations would have a greater impact on this young university. “Compared with the older institutions, CityU was receiving less help in the form of donations from well-established alumni. That’s why I thought more help was needed from those who could help.” Since joining the Board of Governors of the CityU Foundation, he has seen how the President, his deputies and the faculty and staff members alike contribute in various ways to the University and the students. For example, in recent years, many students have won prizes and titles in local and international competitions, revealing the great efforts they and their teachers have made, he said. Mr Chan said he was happy to have witnessed the major advances that CityU has achieved recently, such as the setting up of the CityU Foundation and the School of Veterinary

a worthy example to the younger generation. From his life’s experience, Mr Chan knows well that one’s mentality and attitudes matter far more than the deeds performed, and that the wisdom of “knowing thyself” is far more important than just being smart.
陳先生對城大近年的重要發展感到欣喜， 例如城大基金和動物醫學院的成立。他期 望城大在研究和教學、畢業生質素、大學 排名等各方面都會更上層樓；也深信城大 基金雖然剛成立，卻是重要的開始。
積極投入慈善事業，回饋社會，令人崇 敬，是年輕人學習的好榜樣。 經過生活的歷練，陳先生明白，心態比 事情重要，而「自知之明」亦比「聰明」要 緊。他願以「一生平凡事，平凡過一生； 做好平凡事，一生不平凡」與《今日城 大》的讀者共勉。

學生心聲
立體打印不僅簡化了製造過程，在個 人、社會及工作層面上還促進了我的專 業發展。 自從在主修課程主任、資訊系統學系副教授 郭致偉博士的引導下認識了立體打印技術 後，我就對立體打印的商業用途很好奇。 後來，更被立體打印在不同行業的廣泛應 用所吸引而加入城大精進教育實驗室當學 生助手，冀能深入了解立體打印技術。這 所實驗室設備精良，配有專業軟件與數台 立體打印機。 個人發展 設計產品時，一般都是先設想其最外層部 分，比如形狀與大小，然後才考慮細節。 但是，利用電腦輔助設計 (CAD) 描畫模型 則剛好相反。使用製造水平的CAD製圖軟 件，所設計的每個部分都有數學式關聯。無 論是長度、角度，或從一個平面到另一個平 面，各個部分都必須精確計量與裝配。就以 我設計的移動擴音器為例，其內部齒輪的數 目及振動速度均須以人手自行輸入，以產生 電腦動畫並作可行性檢查。
The award-winning movable speaker 獲獎的移動擴音器
精進教育實驗室主管范子祺先生對我說， 「屢敗屢試」是創新過程中的一個重要步 驟。失敗向來是最好的老師，總有可借鑒之 處。經過多次嘗試之後，我學會在加倍注重 細節的同時，亦不忘新創意的大方向。令我 驚喜的是，這種心態不但使我的設計更好， 對日常生活也有益處，無論是制定商業計 劃，還是規劃每天日程，注重細節，而又堅 持大方向，使我的整體表現更加出色！
啟發。例如，在設計移動擴音器時，我聽 取了三位同學的專業意見；他們分別來自 電子工程學系、物理及材料科學系、建築 學及土木工程學系。此外，實驗室的其他 學生助手對我的幫助亦很大，他們是精通 Maya, ThinkerCAD和ColourIT等多款軟件 的高手。與他們合作，不但改善了我的模 型，也提升了我使用軟件的技能。

有了他們的幫助，我的隊伍憑著移動擴音 器榮獲2015年Printisable 3D設計比賽冠 軍。結識新朋友、集思廣益、在比賽期間 互相幫助，這些成了我大學生活中一些最 美好的回憶。 未來發展 立體打印正在改變全球商業模式。終有一 天，家家戶戶都會有一台立體打印機，把 我們所需的一切東西打印出來，包括食 品、衣服、用具等等。這對物流、零售商 及製造商都是巨大挑戰。目前，可供立體 打印用的材料愈來愈多，比如鐵、不同彈 性的塑膠，以及食材和生物成分。立體打 印將不再局限於製作原型或機械零件，還 會擴大到雜貨、醫學及食品等行業。

電影雖然是西方發明 的，但在其誕生一年 之後已傳入東方。回望 電影120年來的發展，亞 洲地區與歐美一樣有著深 厚綿長的軌跡。然而，現 時的電影教科書通常只側重 西方，在講述世界電影發展史 時，極少論及東西方電影之間的 關係。 本書旨在彌補上述缺失，並探究電影技術相對滯後的發展中國 家出現的電影「新浪潮」，為何常會得到西方的讚揚。此外， 本書闡述了電影史中經常遭忽視的各國先鋒女性導演的貢獻， 並探討促成各種電影運動的藝術、經濟及社會因素，讀者可透 過本書所述的電影發展史，了解東西方文化如何相互影響與 滲透。
