PolyU’s master programme in nutrition with register system helps boost professional level

Launched last year, PolyU's MSc in Nutrition and Healthy Ageing programme has introduced the registered nutritionist system, which not only enhances the professional level of graduates, but also ensures the quality of service of the industry. Professor Wong Man-sau of Department of Applied Biology and Chemical Technology at PolyU said the programme is the first in Hong Kong that provides workplace learning in the community to its students. The programme aims at providing a unique and profession-oriented education opportunity for bachelor degree holders with relevant backgrounds, who want to contribute to the health and well-being of the ageing population. The curriculum design is based on the requirements of the UK Association for Nutrition for programme accreditation. Graduates can apply for direct entry as Registered Associate Nutritionists, with the prospect of becoming Registered Nutritionists with three years' experience. Professor Wong said currently there is no law in place regulating the qualification of nutritionists. Registered Nutritionists will become a new professional qualification in Hong Kong, which will help improve the graduates' status as well as regulate the industry.   明報 F22 理大「營養與健康活齡理學碩士課程」致力培育營養學家 推廣社區營養為公眾健康把關 5 February 2021

Prof. Jintu Fan introduces future fabrics in TVB programme

Prof. Jintu Fan, Chair Professor and Head of Institute of Textile and Clothing at PolyU, was featured in TVB programme Futurescope (看出個未來) to introduce the future fabrics developed by PolyU. PolyU has cooperated with various brands to launch series of functional clothing, including the sportswear worn by Hong Kong athletes in the Winter Olympics. Prof. Fan believes integrating smart devices into sportswear will become the trend in the future. He pointed out that while wearable electronic devices has increased by 28% per annum in the past decade, they anticipated that the growth will reach 40% per annum in the next ten years. He revealed that his team is conducting a research on "skin-like" fabric. Unlike the existing breathable fabrics in the market, the "skin-like" fabric even mimics the sweating glands underneath our skin, as such the water transmission rate is much higher than the commercial breathable fabrics. Apart from human body, animals and plants are also the imitating targets when designing fabrics. One of the PolyU's invention is a thin membrane that imitates leaves. Like a leaf, there are pores on the membrane which will open under humid environment, so provides a better ventilation and hence comfortability to the wearer. It is believed that amid the pandemic, the use of such future fabrics will be widely extended, including personal protection gears. Prof. Fan also expects that the weather will be getting more and more extreme in the future, and these fabrics will help our body maintaining normal biological status under these extreme circumstances.

PolyU launches first real-time remote laboratory in Asia

PolyU and the secondary school users recently shared the benefits of the "Borderless Lab 365", developed and launched by PolyU in 2019 and is also the first real-time remote laboratory in Asia. The Lab allows both university and secondary students to perform experiments remotely anywhere and anytime. Dr Mak Chee-leung, Associate Professor of the Department of Applied Physics, said after logging in, students can control remotely the equipment in PolyU's laboratory and adjust the parameters themselves to perform experiments and collect data for scientific analysis. With over HK$5 million funded by the Quality Education Fund, the platform has benefitted more than 350 secondary students from about 20 secondary schools. Over 350 PolyU students have used the platform as well. Six experiments are available currently in the platform. Dr Mak said they are targeting at increasing the number of experiments to 15 by the end of this year, and planning to cover more subjects and other elements like virtual reality. 香港新聞網 港理大建亞洲首個“遙控”實驗室 25 January 2021 香港01 理大團隊研實時遙距實驗平台 疫情下助學生無需返校亦可做實驗 25 January 2021 經濟通 理大網上科學平台 中學生全天候遙距實驗 25 January 2021 教育家報 理大研發「全天候科學實驗室」亞洲區首個同類型實時遙距實驗平台 25 January 2021 looop.hk 理大建「全天候實驗室」中學生可遙距操作 25 January 2021 中國新聞網 香港理工大学研发出亚洲首个远距离“遥控”实验室 25 January 2021 封面 香港理工大学研发出亚洲首个远距离“遥控”实验室 25 January 2021 東方網 香港理工大学研发出亚洲首个远距离“遥控”实验室 25 January 2021 光明網 香港理工大学研发出亚洲首个远距离“遥控”实验室 25 January 2021 中新網 香港理工大学研发出亚洲首个远距离“遥控”实验室 25 January 2021 東方日報 A13 亞洲首個理大實時遙距平台 學生隔空做實驗 25 January 2021 蘋果日報 理大全天候科學實驗室 讓中學生家中上實驗課 25 January 2021 明報 A08 理大遙距實驗平台 教師薦SBA疫下採用 25 January 2021 經濟日報 A15 理大全天候實驗室 提升教學效益 25 January 2021 星島日報 F01 理大遙距平台升級 助高中生疫下做實驗 25 January 2021 AM730 A12 理大創遙距實驗室 中學生「隔著螢幕」做實驗 25 January 2021 大公報 A07 理大“全天候实验室” 中学生可遥距操作 25 January 2021 文匯報 A07 理大建亞洲首個「遙控」實驗室 25 January 2021 經濟一周 理大創遙距實驗室 中學生「隔著螢幕」做實驗 25 January 2021 晴報 P09 理大網上科學平台 中學生全天候遙距實驗 25 January 2021

凍牆搶走體溫 腹額冰冷 低溫症響警號

天文台上周發布「新界多處地區有顯著的輻射冷卻」，部分地區氣溫降至3℃或以下。原來不止戶外地方，連家中都會出現輻射冷卻，再加上傳導效應，不但令室溫下降，還吸走人體熱量。 英國國民保健服務（NHS）建議，冬天時室內溫度應不低於18℃，是否適用於香港？近期持續寒冷，室溫隨時跌破18℃，即使關緊門窗仍然凍入心脾，如何保暖？ 熱力有3種傳播方法，包括傳導（conduction）、輻射（radiation）和對流（convection）；香港理工大學應用物理學系副教授曾遠康表示，「輻射冷卻效應」及「對流冷卻效應」都會引致室溫下降，令人寒冷。 他解釋，根據熱力學第零及第二定律（zeroth and second law of thermodynamics），能量傾向平均分佈達到平衡（thermal equilibrium），以及熱量會由高溫傳向低溫。故當天氣寒冷，氣溫長期維持在10℃左右時，室內牆壁會因為傳導效應，由標準室溫約20℃慢慢冷卻至10℃左右。「輻射冷卻效應」指的就是人體表面溫度（約36℃）與室內牆壁表面溫度（約10℃）出現溫差，人體熱量於是經輻射傳給環境，令人寒冷。 香港理工大學屋宇設備工程學系副系主任及副教授梅國威補充，熱輻射是物體用電磁波（electromagnetic wave）將熱能向外散發的傳熱方式，如暖爐向人體散發熱量，人會溫暖；相反，當人的熱量被其他物件吸收，便有「輻射冷卻」。 心臟血流量增多 可致心臟病 長期處於寒冷環境，可引起各種疾病。香港急症科醫學院院長胡詠儀表示，在低溫環境下，為減低熱量流失，身體會減少血液流至四肢，導致手腳冰冷；同時，流到心臟的血流量增多，增加心臟負擔，導致因急性心臟病、低溫症而送到急症室的個案增加，長者更是低溫症的高危族。胡解釋，連接腦下垂體的下丘腦負責控制對冷熱溫度的感覺，但長者調節體溫、感覺冷熱的能力較低，未必有足夠判斷力適時添加衣物，建議大家多關心和探望長者，尤其是獨居的長者。留意他們的精神狀態，如果對答如流，代表血液循環到腦部充足，便毋須太過擔心。若長者手腳太冰冷，應開暖爐、穿上手套及襪子保暖。 徵兆：發抖、精神紊亂 人體具有體溫調節機能，一般維持在37℃左右，稱為核心溫度。若接近人體核心溫度的額頭、腹部等部位持續冰冷，並同時出現發抖及精神紊亂，則需要特別留意，可能是低溫症徵兆。 詳情轉載自明報 > 副刊 > 健康

Two PolyU projects secure UGC’s COVID-19 research funding

The funding results of the One-off Collaborative Research Fund (CRF) 2020/21 and One-off CRF COVID-19 and Novel Infectious Disease Exercise (One-off CRF exercise) allocated by the University Grants Committee (UGC) and Research Grants Council (RGC) was released recently. 27 COVID-19 related collaborative research projects led by various local universities will share an additional HK$150 million. Among them, two projects coordinated by PolyU have secured about HK$13 million in total. One of the PolyU projects, multi-level synergistic COVID-19 point-of-care diagnostics based on upconversion luminescence biosensing platform, will receive a funding of over HK$8.4 million. Led by Professor Hao Jianhua, Associate Head and Professor of Department of Applied Physics, the project aims to provide multi-level synergistic diagnostics platform and reflect full spectrum of infected patients’ information for point-of-care diagnostics, which could help avoid false-positive or false-negative results. Another project Effective Ventilation Strategies for Mitigating Infection Risks in Hospitals, led by Dr Mui Kwok-wai Horace, Associate Head and Associate Professor of Department of Building Services Engineering, is allocated a funding of over HK$4.4 million. The project aims to evaluate the infection risk of various ventilation strategies in hospitals with the aid of computational modelling. The One-off CRF was launched last year in view of the COVID-19 outbreak. The University of Hong Kong and City University share the funding with 15 and four projects respectively, while the Chinese University, the Hong Kong University of Science and Technology, the Baptist University and the Education University have one to two projects each.
