Hong Kong is one of the cities with the highest penetration rate of mobile devices in the world. There is the potential for Hong Kong to be a leader of mobile commerce. Recently, the six local mobile network operators stimulated usage of SMS to promote mobile Internet markets. In addition, the Hongkong Post launched the mobile digital certificates for community-wide adoption of mobile commerce. However, the customers are not buying what might be expected, and mobile commerce is a relatively new concept to most of Hong Kong people. The initial consumers are fundamentally committed to new technology and like getting their hands on the latest innovations. They should be the major market segment in this early phase of development. Hong Kong is an international financial center, and the premier gateway for trade and investment moving into and out of China. This offers an opportunity that the information and news provides a valuable market to mobile commerce. This paper will discuss these factors and analyze the mobile commerce market in Hong Kong.

This chapter proposes the hybrid inquiry-based learning (HIBL) model, a novel pedagogical model based on inquiry-based learning (IBL). In IBL, learning is achieved by questioning and learners are encouraged to invent new hypotheses instead of investigating questions posed by the instructor. This chapter first provides a holistic description of IBL. It begins with a brief history and survey on learning perspectives, pedagogical background of IBL is also provided. The IBL model, its implementations and variations, as well as the comparison of its pedagogical features against traditional teaching approaches are also given. This chapter further contributes the hybrid inquiry-based learning (HIBL) model, a new IBL model that integrates traditional and ICT-based implementations of IBL. By leveraging on the advantages of both classroom-based and web-based learning, the best sides of IBL can be elicited. A detailed example in Information Security education is also provided to illustrate the HIBL model.

Background:An in-house self-held respiration monitoring device (SHRMD) was developed for providing deep inspiration breath hold (DIBH) radiotherapy. The use of SHRMD is evaluated in terms of reproducibility, stability and heart dose reduction.Methods and materials:Sixteen patients receiving radiotherapy of left breast cancer were planned for treatment with both a free breathing (FB) scan and a DIBH scan. Both FB and DIBH plans were generated for comparison of the heart, left anterior descending (LAD) artery and lung dose. All patients received their treatments with DIBH using SHRMD. Megavoltage cine images were acquired during treatments for evaluating the reproducibility and stability of treatment position using SHRMD.Results:Compared with FB plans, the maximum dose to the heart by DIBH technique with SHRMD was reduced by 29·9 ± 15·6%; and the maximum dose of the LAD artery was reduced by 41·6 ± 18·3%. The inter-fractional overall mean error was 0·01 cm and the intra-fractional overall mean error was 0·04 cm.Conclusion:This study demonstrated the potential benefits of using the SHRMD for DIBH to reduce the heart and LAD dose. The patients were able to perform stable and reproducible DIBHs.
