New discovery for water repellent material 科研新發現：疏水性能最佳材料
From the Editor
Apps have transformed the way we communicate and access information, making it easier to navigate through the wealth of information in cyberspace. They also present faculty and students with a range of teaching, learning and research possibilities. Our state-ofthe-art facilities on campus provide the space and technical support for the CityU community to test out their ideas for new apps within our Discovery-enriched Curriculum. Read about some of the achievements in this field in this issue of our magazine. Building on the technology theme, we also take a peek at some incredible game innovations underway at the University and some exciting areas of research that touch on, for instance, new water repellent materials. We will follow up on the highly successful Sustainability Summit that we discussed in the last issue of CityU Today as well. Happy reading!

FoodServe:

Hong Kong is a food paradise. We have everything from Michelin-starred restaurants to hole-in-the-wall eateries, and so it is not difficult for foodies to satisfy their taste buds. However, we often face problems searching for suitable restaurants, such as having to wait a long time to be served and having difficulty getting through the line for food delivery during rush hour. What’s more, restaurants may lose their reputation for poor service if there are too many customers.

提問影響整個地球的全球性問題，固然需要勇氣；而要面對 一群專家挺身直問，更須格外大膽。 城大2014年10月底舉辦的「可持續發展高峰會」大獲成功。會議期 間，參加「大問題擂台賽」而勝出的學生，正是敢於提問的勇士。 生物及化學系副教授林潤華博士參與組織了這場擂台賽，他說： 「擂台賽中的城大及本地中學優勝者，有機會與全球知名的學者 交流，討論環境變化及可持續發展等問題。」 這種機會確實難得，因為學校教育的模式通常是老師問、學生答， 在香港的中學尤其如此。 林博士說：「年輕人參加擂台賽，就有機會在一個莊重的學術環境 中提出他們想問的問題，無論問題多麼不同尋常，都可請專家解 答，而這些專家他們平常無緣見面交談。」
「大問題擂台賽」是一個別具特色的網上競賽，旨在促使學生加深 認識可持續發展所面臨的困難，同時激發他們對相關問題的興趣。 參賽者十分踴躍：城大及15所中學共有809名學生提交了919條問 題。 城大／中學組別共頒發十多個獎項，包括大獎（圖一）、優異獎 （圖二），還有「最踴躍參與獎」 （圖三）；所有參賽者均獲頒電子 證書。 城大有三位學生獲得大獎，其中法律學院的Hui Raphael Yulhay 獲選向專家提問：「如何鼓勵企業家在營商時保持『承擔企業社會 責任』的做法？」；在中學組別的三名大獎獲得者之中，宣道會陳 瑞芝紀念中學的張恩婷獲選向專家提問：「怎樣能增加香港可用的 土地面積而同時不破壞生態環境？」為了擴大成效，城大在擂台賽 後造訪了學生參賽最踴躍的幾所中學。

林博士說：「我們發現，這次擂台賽與本地中學開設新通識教育科 目的精神十分契合。學生的反饋意見表明，他們十分珍惜與高峰會 專家對話的機會。」
她還說：「我們希望鼓勵大家反省：在可持續發展問題上眾人齊心 協力固然大有必要，但也須考慮他人有不願合作的權利。換言之， 自由意志、個人利益的觀念，也應予考慮。」
「大問題擂台賽」為可持續發展高峰會增添了啟人深思的一面。高 峰會的定位是一場思想的盛會，各種範疇的學者、專家、學生得以 聚首一堂互相切磋，進行李芝蘭教授所形容的「反省」。
界定本次峰會知識基礎的背景資料當中，包括一篇關於藝術與人文 的短論。此類學科的範圍廣闊，但在有關可持續發展的討論中往往 遭到忽視，與商業與社會科學、自然科學與工程學相比，往往相形 失色。
她解釋說：「本次高峰會的討論重點，與大眾通常預期一場此類議 題的高峰會要討論的不盡相同。」李教授現任城大協理學務副校長 （策略規劃），並兼任公共政策學系政治學教授。 李教授專責督導城大的可持續發展事宜。她說：「我們決定，在探 討本次會議的主題時應不局限於科學，例如不僅僅討論碳排放回 收、生物燃料等議題。我們希望藉此激發大家思考可持續發展議題 的人類因素，思考如何幫助個人與社會確立自己的核心觀念和倫 理原則，並認識這些觀念、原則與可持續發展的實踐及政策有何關 聯。」
高峰會之後，城大再接再厲，成為本港率先加入國際氣候變化計劃 「氣候合作」 （Connect4Climate）的大學。該組織旨在提高大眾對 氣候變化的認識，鼓勵各方採取行動保護環境。 「氣候合作」的發起者是世界銀行、意大利環境部、全球環境基 金，該聯盟成立於2011年，現在全球各地有140多個合作夥伴。這 個全球合作組織致力促進有關氣候變化的溝通交流。

Experiencing Hong Kong as a new international student:
The experience of an Afrikaner in Hong Kong By: Jacobus du Plessis School of Law
Where am I from, and what’s my story, you ask? Well, simply my name is Jacobus du Plessis, an Afrikaner from South Africa. This year I started my LLB (law) degree here at CityU as a full-time student. I was drawn to Hong Kong as a place of opportunity and I had heard many good things about the quality of education here. Studying law in Hong Kong offers many unique opportunities for me, ranging purely from future jobprospects, to merely the chance to get to interact with a diaspora of different peoples and cultures. So, in case you were wondering, choosing to come study in Hong Kong was an easy choice to make. How different is Hong Kong from my home town? I grew up in a relatively small town in South Africa with a population of about 4,000 people. So as you can imagine, moving from that small town to this SuperCity was a massive adjustment for me. The differences between Hong Kong and my hometown are endless: the most obvious difference though is the hectic pace of life in Hong Kong and the never ending

你想問，我從哪裏來，有什麼經歷？簡單說吧，我叫Jacobus du Plessis，是來 自南非的白人學生。我今年入讀城大，是修讀法律學榮譽學士課程的全日制學生。 香港是一個充滿機會的地方，這吸引了我，況且我對香港的優質教育聞名已久。來 香港修讀法律，使我有很多特別的機會，這可以是將來的就業前景，也可以是有 機會與一大群各種民族和文化的人交往。所以，你想知道我是否難以決定來香港讀 書，我可以告訴你，一點也不難。

香港跟我的故鄉差別有多大呢？我生長於南 非一個小鎮，鎮上大概只有4,000人。可想 而知，從那個小鎮來到香港這個超級大都 市，我要適應的事情太多了。香港與我家 鄉小鎮的差別真是說不完。最明顯的差別就 是，香港的生活節奏緊湊，似乎人人都是四 處跑個不停。還有一件事，我好久才適應過 來，就是香港的飲食大不相同。坦白說，我 仍然不時想念南非家鄉菜，但已逐漸喜歡上 品類豐富的中國菜了。
好吧，你們問夠了。我想，大家要互相認 識，最好的辦法就是聽我談談自己的經歷， 看我這個初來香港的學生如何努力融入新 的環境。 你聽說過「文化衝擊的五階段模式」吧？這 說的是一個人初到一個國家或城市之後經 歷的幾個適應階段，大體上是這樣的：第 一階段是蜜月期，你發現在這個新的地方樣 樣事情都很迷人，令人振奮；第二階段是苦 惱期，你會發現，第一個星期中令人興奮的 事情，現在開始使生活有點難過了。第三階 段是再融入期，你開始覺得還是「老家」最 好，自問為何當初要來這裏。第四階段是自 治期，你終於感到開始能適應，能夠在這個 社會生活了。第五階段，你終於來到獨立 期，能夠接受新的文化，再次感覺自如了。 我想，為了讓你明白一個外國學生在香港的 感受，我要把自己的經歷一一說出來，你才 會了解在香港做一個「新來人」的好與壞。 我希望，經由這個小小的實驗，能夠幫助新 來的外國學生較容易融入城大。 我在香港的最初幾個星期，感覺簡直是 「勁爆」！香港各處的小角落，能去的我都 去了；自己與香港人的每一處微小差別都令 我驚訝。凡是遊客到了香港必遊必試的， 我件件不漏，每一刻都開心。不過我很快 覺察到，要真正了解一個地方跟自己的家 鄉有何不同，就必須去做一些日常瑣事， 例如買日用品，簽一份手機合約，或者僅 僅是買晚餐。
談時，有些人聽不懂我說的話；有些事情 在香港的做法，跟我所習慣的很不一樣。 這些事都使我灰心喪氣，脾氣也變得有點 暴躁了。我開始自問當初為什麼決定離開 南非家鄉，在那兒似乎事事都輕鬆易做。 舉個例子，遇到聽不懂英語的人，我會覺 得實在沮喪。不過，這個階段為時甚短， 我不久就習慣了新環境，高高興興欣賞香 港的多樣化。 原先令我難受的那些小事，忽然之間變得 特別有意思了。我不再強求他人懂英語， 倒是自己開始學一點粵語，以便順利辦成 一些小事。我不再為南非和香港的某些文 化差異而煩惱，開始欣然接受差異，學香 港人那樣生活。這些技能與態度方面的小 小改變，讓我重新認識到自己來香港求學 的決定是對的。在我的眼裏，香港又是我 先前所知的那個偉大城市了。 要不是城大內地及對外事務處的人員盡力 協助，我就不可能那樣再度適應；要不是 朋友們耐心聽我亂七八糟講粵語，還強忍 得住不放聲大笑，我的粵語就不會進步。 我想，最重要的是，我要多謝香港人，他 們自己生活得匆匆忙忙，還好心擠出時間 來幫助異鄉來客。 我想，聽我這樣回顧自己在香港的適應 過程，對於一個人離開祖國來到香港這樣 多彩多姿、令人興奮的異鄉的感受，你多 少能夠體會了吧。我期待在這個美麗的都 市再待四年，甚至更久。

Martial arts and yoga: the former is rumbustious and the latter pliable. How can one blend the two together? CityU alumna Ms Sally Chung Sau-yee did just that, creatively integrating yoga with martial arts.
By Cathy Lau
文：劉靜萍
“When I was young I was always bullied. When I was studying A-levels, I chose to learn Mi Zong Luo Han because it is more focused on body stretching and basic skills than other schools of martial arts. I hoped I would be able to protect myself with kung fu,” said Ms Chung who has a BSc (Hons) in Applied Physics, a postgraduate certificate in Hong Kong Law, and an MPhil in Applied Physics from CityU. Her school of martial arts, known as Mi Zong Luo Han (Lost Track Arhat), emphasises foot and legwork, and requires practitioners to maintain great resolve and perseverance during training.
