Facial information is, however, easy to capture and reproduce, making face authentication systems vulnerable to attack. The System Security Lab led by Prof. Zhang Kehuan (right) of the Department of Information Engineering has designed a new challenge-response protocol for liveness detection, Face Flashing. Light from a display screen will be projected onto a human face and the reflected light will be captured by a camera for analysis, enabling the system to differentiate real human faces from fake ones. 睡一睡，心血管病莫伴隨 Catch Some Z’s to Avoid Cardiovascular Disease 醫學院研究團隊為一百四十二名青少年量度「頸動脈 內膜－中膜厚度」（簡稱CIMT），並記錄他們的平均 睡眠時數，發現近四成參與研究者每日平均睡眠時數 少於美國全國睡眠基金會建議的最少八小時，更發現 青少年睡得愈少，他們的CIMT便愈厚，意味着他們日 後罹患心血管疾病的風險愈高。研究結果已發表於 The Journal of Pediatrics 。 The researchers of the Faculty of Medicine measured the Carotid Intima-Media Thickness (CIMT) of 142 adolescents and recorded their mean sleep duration. Results showed that almost 40% of participants did not get at least eight hours of sleep as recommended by the National Sleep Foundation. It was also seen that shorter sleep duration is associated with increased CIMT, which implies higher risk of cardiovascular disease in the future. The study results have been published in The Journal of Pediatrics . 孕育年輕社會創業家 Young Talent, Big Business 社創領袖獎頒獎典禮2018暨尤努斯社會事業講壇於 7月23日在中大舉行，2006年諾貝爾和平獎得主穆罕 默德·尤努斯教授（中）於典禮擔任頒獎嘉賓，並於社 會事業講壇中分享他對「三零世界」（零貧窮、零失業 和零淨碳排放）的盼望。中大社會及公民參與督導委員 會聯席主席沈祖堯教授（右二）希望大學可以培育和幫 助年輕人創辦社會事業，為有志之士提供訓練及實踐 的機會。 The S.I. Leadership Award Ceremony 2018 and Yunus Social Business Seminar were held at CUHK on 23 July. Prof. Muhammad Yunus (centre), Nobel Peace Laureate in 2006, presented the awards at the ceremony and delivered a speech at the seminar. He shared his hopes for the ‘world of three zeros’ (zero poverty, zero unemployment and zero net carbon emissions). Prof. Joseph J.Y. Sung (2nd right), co-chairman of the Steering Committee for Promoting Personal Development through Social and Civic Engagement of CUHK, hoped the University would be a platform which incubates and assists young people in starting their social enterprises. 中大（深圳）成立世界級運籌科學研究院 CUHK (SZ)’s World-class Institute for Data and Decision Analytics 中大（深圳）於7月20日宣布成立資料與運籌科學研究院，由世界 知名學者戴建崗教授和張寅教授擔任共同院長。研究院將與該校 理工學院和經管學院密切合作，專注於運籌學、資訊工程、統計 學、運營管理和決策科學等研究領域，以及相關交叉領域的科學研 究與人才培養工作。 CUHK (SZ) announced the establishment of the Institute for Data and Decision Analytics on 20 July, with two world-renowned scholars Prof. Jim Dai and Prof. Zhang Yin serving as co- directors. Working closely with the School of Management and Economics, the Institute will focus on scientific research and talent development in research areas such as operations research, information engineering, statistics, operations management and decision science. 文憑試優秀學生加入中大 Outstanding HKDSE Students Admitted 中大今年共取錄二千八百八十六名文憑試考生，99.5%為Band A 考生。繼去年錄取全港成績最佳考生，中大今年再創佳績，共錄取 三位考獲七科5**的考生，以及十一位考獲六科5**的考生。考獲七 科5**的三人將分別入讀醫學（環球醫學領袖培訓專修）、環球商 業學及環球經濟與金融跨學科主修課程。 CUHK has admitted 2,886 HKDSE students, 99.5% of which were Band A students.
