Objective: To investigate changes in the median nerve, retinaculum, and carpal tunnel on ultrasound after successful endoscopic carpal tunnel release (ECTR). Materials and Methods: This prospective study involved 37 wrists in 35 patients (5 male, 30 female; mean age ± standard deviation [SD], 56.9 ± 6.7 years) with primary carpal tunnel syndrome (CTS). An in-house developed scoring system (0–3) was used to gauge the clinical improvement after ECTR. Ultrasound was performed before ECTR, and at 1, 3, and 12 months post-ECTR. Changes in the median nerve, flexor retinaculum, and carpal tunnel morphology on ultrasound after ECTR were analyzed. Ultrasound parameters for different clinical improvement groups were compared. Results: All patients improved clinically after ECTR. The average clinical improvement score ± SD at 12 months post-ECTR was 2.2 ± 0.7. The median nerve cross-sectional area proximal and distal to the tunnel decreased at all time intervals post- ECTR but remained swollen compared to normal values. Serial changes in the median nerve caliber and retinacular bowing after ECTR were more pronounced at the tunnel outlet than at the tunnel inlet. The flexor retinaculum had reformed in 25 (68%) of 37 wrists after 12 months. Conclusion: Postoperative changes in median nerve and retinaculum parameters were most pronounced at the tunnel outlet. Even in patients with clinical improvement after ECTR, nearly all ultrasound parameters remain abnormal at one year post- ECTR. These ultrasound parameters should not necessarily be relied upon to diagnose persistent CTS after ECTR.

Wing Lam FOK,Jia Huan LIEW,Yik Hei SUNG 한국양서ㆍ파충류학회 2023 한국양서·파충류학회 학술대회 Vol.2023 No.07

Freshwater turtles and tortoises are one of the most threatened groups of animals in the world, with 60% of species being threatened. Hong Kong has five freshwater turtle species which are threatened due to illegal hunting and habitat loss. The conservation of freshwater turtles is important because overseas studies have showed that some species play important ecological roles, for example, facilitating storage and cross-ecosystem transportation of energy and minerals, acting as predators and prey, dispersing and enhancing germination rate of seeds, and assisting restoration of degraded ecosystems. Since turtles are rare across Asia, little is known about their ecological roles. In this study, we investigated the ecological roles of the critically endangered Big-headed Turtle (Platysternon megacephalum) using three approaches. First, we conducted behavioural experiments in the laboratory to test the predatory effect of P. megacephalum on the behaviour and growth rate of freshwater snails (Sulcospira hainanensis). Second, we used bulk stable isotope analysis to quantify the role of P. megacephalum in the food web, and used removal models to estimate how the ‘extinction’ of P. megacephalum may affect the food web. Third, we compared the macroinvertebrate community structure and ecosystem processes (leaf litter decomposition and primary production rates) between streams with and without turtles. Overall, the results of this study enhance our understanding of the ecological roles played by P. megacephalum and contributes to the conservation of endangered freshwater turtle species in Asia.

Reform Disconnections between the Free Quality Kindergarten Education Scheme and Kindergartens in Hong Kong

Wing Sze Carol Chan 환태평양유아교육연구학회 2020 Asia-Pacific journal of research in early childhoo Vol.14 No.1

National Association of Education for Young Children (NAEYC) (2009) stated early childhood education (ECE) practitioners are key agents who develop quality assured curriculum and conduct teaching through developmentally-appropriate practice (DAP). They play the vital role in providing quality education for enhancing children s whole-person development in early years, in the sense that, their importance and significance towards children’s development is an undeniable fact. In order to retain and maintain a stable teaching team in kindergartens, whether or not ECE practitioners’ salary could be guaranteed with statutory increment are the key concerns of different stakeholders in ECE, where appropriate, the Government of Hong Kong Special Administrative Region (HKSAR) plays a pre-dominant role in policy-making on the subsidy of ECE in Hong Kong. This paper therefore examined the key initiative on the salary adjustment for kindergarten practitioners through the implementation of the Free Quality Kindergarten Education Scheme (Scheme) starting from 2017/18 school year (Education Bureau, 2017b). The latest three policy addresses on the direct subsidy to kindergartens joining the Scheme (Scheme-KGs), announced by the Government of HKSAR in 2016, 2017 and 2018, were extracted for examining the fault-lines in terms of direct subsidies for Scheme-KGs via content analysis. Developed by Walker (2006), the Five Reform Disconnections were adopted as theoretical framework for analyzing the disconnection between the Scheme and teachers expectation on their salary adjustment. Practical recommendations were provided for alleviating the said disconnection.

釋論香港中學文言文的敎學難點及其策略

( Wing Tat Lee ) 한국한자한문교육학회 2014 漢字 漢文敎育 Vol.33 No.-

문언문의 한자·어휘 교육은 중학교 중문 교육의 필수적인 부분이다. 이전에 홍콩의 중학교에서 시험을 치르었던 아니던 간에, 문언문은 최근 중학교 졸업시험에서 그 지식과 이해가 포함되고 있으며, 중국 어문교과의 읽기 교과에서도 일정한 비율을 차지하고 있디 때문에 그 중요성은 소홓히 할 수 없다. 그러한 가운데 학생들이 효과적으로 문언문 한자·어휘를 분석하고 습득하게 교육시킬 수 있는 전략과 방법은 바로 학생들의 읽기 능력을 향상시키는 중요한 관건이 된다. 이를 위해 본고에서는 필자 개인의 경험과 홍콩의 문언문 읽기 교육의 실제를 결합하여 구체적이고 실천적인 교수-학습 방법을 탐구해본다. 우선 홍콩의 문언문교육의 발전을 회고하여 보고, 이전의 문언문 교육이 가졌던 난점을 개괄한 후, 고대 한어의 어법적 특징에 집중하여 몇 가지 문언문 교육에서 효과적인 방법과 전략을 제시하여 이를 통해 학생들의 문언문에서의 한자와 어휘와 대한 인식과 이해, 흥미를 증가시키고자 한다. Teaching of Classical Chinese Characters (Wenyan) is a crucial part of Chinese Language education in Hong Kong Secondary School. Be it the former Hong Kong Certificate Education Examination or the Hong Kong Diploma of Secondary Education, the reading comprehension of Classical Chinese passages remains a major section of the Chinese Language Examination, carrying a high assessment weightage. Thus, it is important to improve students` reading performance by equipping them with effective reading strategies and skills to grasp the meaning of Classical Chinese Characters and phrases. For this purpose, based on the situation of Hong Kong secondary education and the author`s teaching experience, this paper attempts to discuss teaching and learning strategies for Classical Chinese reading in a practical way. It will start by reviewing the development of Hong Kong Classical Chinese education, then trying to find out the teaching and learning difficulties faced by teachers and students. Based on the linguistic features of classical Chinese, discussions about teaching strategies will be followed by the review. Suggestions on effective teaching strategies to enhance students` reading literacy and interest will be made in this paper.

REVIEWS : Emerging strategies for the treatment of pulmonary tuberculosis: promise and limitations?

( Wing Wai Yew ),( Won Jung Koh ) 대한내과학회 2016 The Korean Journal of Internal Medicine Vol.31 No.1

A worsening scenario of drug-resistant tuberculosis has increased the need for new treatment strategies to tackle this worldwide emergency. There is a pressing need to simplify and shorten the current 6-month treatment regimen for drug-susceptible tuberculosis. Rifamycins and fluoroquinolones, as well as several new drugs, are potential candidates under evaluation. At the same time, treatment outcomes of patients with drug-resistant tuberculosis should be improved through optimizing the use of fluoroquinolones, repurposed agents and newly developed drugs. In this context, the safety and tolerance of new therapeutic approaches must be addressed.

Examining Students' Creative and Critical Thinking and Student to Student Interactions in an Asynchronous Online Discussion Environment: A Singapore Case Study

Wing Sum Cheung,Khe Foon Hew APEC국제교육협력원 2006 Asia-Pacific Cybereducation Journal Vol.2 No.2

In the last few years there has been a proliferation of asynchronous online discussion forums which have opened up the possibilities for people to exchange ideas at any place and at any time. The literature has documented that asynchronous online discussion has the following desirable characteristics: 1) it may help enhance the participation of students who might be less willing to participate in traditional face-to-face classroom settings due to shyness; and 2) it has the potential to encourage more thoughtful responses since participants can take their own time in composing their thoughts. Nonetheless, despite the promise of asynchronous online discussion to promote rich learning experiences, students do not always make use of its potential. The purpose of this study was to examine how a group of Singapore students interacted with one another, as well as the types of thinking skills, critical or creative thinking, and levels of information processing they exhibited during an asynchronous online discussion. This was an attempt to develop certain guidelines that would help facilitate students' in-depth thinking and promote student-to-student interaction in an online discussion environment.*

High System Performance with Plasmonic Waveguides and Functional Devices

Wing-Ying Kwong 한국전자통신연구원 2010 ETRI Journal Vol.32 No.2

Photonics offers a solution to data communication between logic devices in computing systems; however, the integration of photonic components into electronic chips is rather limited due to their size incompatibility. Dimensions of photonic components are therefore being forced to be scaled down dramatically to achieve a much higher system performance. To integrate these nano-photonic components, surface plasmon-polaritons and/or energy transfer mechanisms are used to form plasmonic chips. In this paper, the operating principle of plasmonic waveguide devices is reviewed within the mid-infrared spectral region at the 2 m to 5 m range, including lossless signal propagation by introducing gain. Experimental results demonstrate that these plasmonic devices, of sizes approximately half of the operating free-space wavelengths, require less gain to achieve lossless propagation. Through optimization of device performance by means of methods such as the use of new plasmonic waveguide materials that exhibit a much lower minimal loss value, these plasmonic devices can significantly impact electronic systems used in data communications, signal processing, and sensors industries.
