A Study of Evidential Particles in Cantonese: the case of wo3 & wo5

The study of evidentiality, which has become an indispensable part of linguistic studies, has had a rapid development in the past few decades. However, studies of evidentiality in Cantonese, one of the major dialects spoken by some 70 million people in Hong Kong, Macau and most of the Guangdong province of China, are relatively few. This paper will firstly introduce evidentiality and its derived concept, mirativity, and subjectivity. Then the features of the Cantonese evidential particles wo3 (mid-level tone), which indicates unexpectedness and noteworthiness, and wo5 (low rising tone), which expresses hearsay information, will be analyzed, and a discussion on how a speaker expresses his or her understanding of the objective world through language will be given

Urban Planning & Development of Kai Tak Area

This project investigated how the land in Kai Tak should be best developed to serve the Hong Kong community based upon our assessments of public needs and interests. Analysis was accomplished by evaluating historical data, obtaining professional opinions, and visiting existing facilities similar to those under discussion for development. The study concludes that proper planning of facilities such as a cruise terminal, sports complex, and metro park is necessary to utilize this substantial area located on Victoria Harbor's waterfront.

Delivery Vehicle and Mechanism for Human Mesenchymal Stem Cells

Several studies have shown that human mesenchymal stem cells (hMSCs) have the potential to be the futute of regenerative medicine based on their ability to rebuild diseased or damaged tissues. The difficulty involved with hMSCs is delivering these cells to the injured tissue site. Injection is the preferred method, but it has been shown that simple injection of hMSCs in media results in extreme turbulent flow, thus killing the cells. Hydrogels have been researched as a form of vehicle for hMSC transport. However, the delivery of the gel and cell viability remain a problem.  This project aims to seek the best overall hydrogel to act as the vehicle as well as a delivery mechanism that allows for simple, safe and convenient transport of hMSCs

Effect of Helicobacter pylori Infection on Symptoms of Gastroenteritis Due to Enteropathogenic Escherichia coli in Adults

Helicobacter pylori can cause hypochlorhydria in some hosts and predispose to diarrheal infections. We tested the hypothesis that chronic H. pylori infection increases the risk of diarrheal illness due to an acid-sensitive organism: enteropathogenic Escherichia coli (EPEC). After testing healthy adult volunteers for H. pylori, 19 infected and 26 uninfected subjects had gastric pH probes placed and were given 5-10 x 10(9) EPEC organisms; six had previously received a proton pump inhibitor. We measured diarrhea and created a composite gastroenteritis severity score based on symptoms in the 48 h following exposure. Outcomes were compared using logistic regression and analysis of covariance. More H. pylori-infected (36.8%) than H. pylori-uninfected subjects (7.7%) were hypochlorhydric (P = 0.02). Six (31.6%) H. pylori-infected and five H. pylori-uninfected subjects (19.2%) developed diarrhea (P = 0.34). Hypochlorhydria was a strong risk factor for diarrhea [odds ratio (OR) 6.25, confidence interval (CI): 1.29-30.35]. After adjusting for hypochlorhydria and EPEC dose, H. pylori was not associated with diarrhea (OR 0.89, CI: 0.17-4.58). Among those with symptoms, H. pylori-infected subjects had lower gastroenteritis severity score than did H. pylori-uninfected subjects (2.6, CI: 1.9-3.4 versus 1.5, CI: 1.1-1.9, P = 0.01), particularly if they were also hypochlorhydric (3.8, CI: 2.3-5.3 versus 1.9, CI: 1.3-2.5, P = 0.02). In adults, H. pylori infection was associated with hypochlorhydria but had no detectable effect on occurrence of diarrhea. Among symptomatic subjects, H. pylori infection decreased severity of gastroenteritis
