喉部神經鞘瘤:一種造成聲帶癱瘓的罕見原因
We present a rare case of schwannoma of the larynx in a 26-year-old Chinese patient. The tumour was excised using a lateral thyrotomy approach, with satisfactory restoration of laryngeal function. The presentation, management, and outcome of treatment for this type of tumour are discussed.published_or_final_versio

Update on management of rhinitis
Rhinitis is common in Hong Kong. The aim of treatment is to control the symptoms and to allow an undisturbed lifestyle without the side-effects of therapy. A secondary goal is to prevent the complication of sinusitis and its sequelae. Most of these goals can be achieved by the combination of anti- allergy management, oral or topical medication and the occasional surgical intervention.published_or_final_versio

Piping classification to metamorphic testing: an empirical study towards better effectiveness for the identification of failures in mesh simplification programs
Mesh simplification is a mainstream technique to render graphics responsively in modern graphical software. However, the graphical nature of the output poses a test oracle problem in testing. Previous work uses pattern classification to identify failures. Although such an approach may be promising, it may conservatively mark the test result of a failure-causing test case as passed. This paper proposes a methodology that pipes the test cases marked as passed by the pattern classification component to a metamorphic testing component to look for missed failures. The empirical study uses three simple and general metamorphic relations as subjects, and the experimental results show a 10 percent improvement of effectiveness in the identification of failures. © 2007 IEEE.Link_to_subscribed_fulltextThis research is supported in part by a grant of the Research Grants Council of Hong Kong (project no. 714504), a grant of City

Finding failures from passed test cases: Improving the pattern classification approach to the testing of mesh simplification programs
Mesh simplification programs create three-dimensional polygonal models similar to an original polygonal model, and yet use fewer polygons. They produce different graphics even though they are based on the same original polygonal model. This results in a test oracle problem. To address the problem, our previous work has developed a technique that uses a reference model of the program under test to train a classifier. Using such an approach may mistakenly mark a failure-causing test case as passed. It lowers the testing effectiveness of revealing failures. This paper suggests piping the test cases marked as passed by a statistical pattern classification module to an analytical metamorphic testing (MT) module. We evaluate our approach empirically using three subject programs with over 2700 program mutants. The result shows that, using a resembling reference model to train a classifier, the integrated approach can significantly improve the failure detection effectiveness of the pattern classification approach. We also explain how MT in our design trades specificity for sensitivity. Copyright © 2009 John Wiley & Sons, Ltd.link_to_subscribed_fulltex
