Investigation on the Integration of “Gao” in Hong Kong Chinese and Mainland Mandarin

From the diachronic dimension,this paper makes a two-way interactive investigation on the integration of Hong Kong Chinese and Mainland Mandarin.“Gao”is a delexical verb in contemporary Chinese.In different words and expressions related to“gao”character,there are mutual absorptions between Chinese mainland and Hong Kong,which is characterized by starting from nothing to something and from less to more.

Doubling over ten years of central obesity in Hong Kong Chinese working men

Obesity is now an epidemic in most parts of the world. In this cross sectional study, we report the most recent data on obesity in Hong Kong Chinese working population and compare the changes over 10 years. Methods Between July 2000 and March 2002, 5882 adult subjects from the working class in Hong Kong were recruited （2716 men （46.2%） and 3166 women （53.8%））. They were randomly selected using computer generated codes according to the distribution of occupational groups. Results of this study were compared with the data collected from a prevalence survey for cardiovascular risk factors in a Hong Kong Chinese working population conducted in 1990 （1513 subjects, 910 men （60.1%） and 603 women （39.9%））. Results Standardized percentages of overweight, obesity, and central obesity, in Hong Kong Chinese working population were 59.7%, 35.0%, 26.7% in men and 32.0%, 21.7%, 26.7% in women. Compared to the data collected in 1990, the percentage of obesity increased by 5% in men and reduced by 6% in women. The percentage of central obesity doubled in men （from 12.2% to 26.7%） but remained stable in women.Conclusions There is a doubling of the percentage of central obesity in Hong Kong Chinese working men over previous decade. Education and proper lifestyle modification program to tackle this social health issue are urgently indicated.

S. E. M. analysis of quartz sand grains from selected Hong Kong and Chinese littoral environments

This pilot study attempts to demonstrate some underlying scanning electron microscopy themes of quartz grain surface textures. A variety of textural patterns and individual features are described for grains selected from various littoral environments. An attempt was made to differentiate samples on surface textures alone, but limitations of using this technique in sedimentological isolation were apparent. Statistical analysis of checklist data and photographic evidence revealed some of the more important feature combinations used in environmental diagnosis. The use of discriminant analysis provided quantitative sample separation.

THE CENTRE FOR ENVIRONMENTAL STUDIES THE CHINESE UNIVERSITY OF HONG KONG

Over the years,population growth and industrial development in Hong Kong has caused serious pollution of the environ-ment.To ensure that we will live in a healthy environment,we need to have a broader view of economic efficiency that incor-porates environmental quality as one of the dimensions of"economic success".This has become an acute problem for theworld in general and Hong Kong in particular.

Chinese Nation Joins in Jubilation for Hong Kong's Return

On July 1, 1997, Hong Kong finally returns to the motherland. July 1 was a day of Chinese national pride. Looking back, Hong Kong experienced great changes and the Chinese nation was subjected to humiliation during the 156 years. The Chinese nation had expected and made unremitting efforts to become stronger for more than 100 years. After resuming sovereignty over Hong Kong, the Chinese government will bring a brighter future to Hong Kong under the policies of "one country, two systems," and "Hong Kong people governing Hong Kong, with a high degree of autonomy." Hong Kong and the mainland will conduct more economic and cultural exchanges and create a more splendid future for the motherland.

Phot2-regulated relocation of NPH_3 mediates phototropic response to high-intensity blue light in Arabidopsis thaliana

Two redundant blue-light receptors, known as phototropins （phot1 and phot2）, influence a variety of physiological responses, including phototropism, chloroplast positioning, and stomatal opening in Arabidopsis thaliana. Whereas photl functions in both low- and high-intensity blue light （HBL）, phot2 functions primarily in HBL. Here, we aimed to elucidate phot2-specific functions by screening for HBL- insensitive mutants among mutagenized Arabidopsis photl mutants. One of the resulting phot2 signaling associated （p2sa） double mutants, phot1 p2sa2, exhibited phototropic defects that could be restored by constitutively expressing NON-PHOTOTROPIC HYPOCOTYL 3 （NPH3）, indicating that P2SA2 was allelic to NPH3. It was observed that NPH3-GFP signal mainly localized to and clustered on the plasma membrane in darkness. This NPH3 clustering on the plasmamembrane was not affected by mutations in genes encoding proteins that interact with N PH3, including PHOT11, PHOT2 and ROOTPHOTOTROPISM 2 （RPT2）. However, the HBL irradiation- mediated release of NPH3 proteins into the cytoplasm was inhibited in photl mutants and enhanced in phot2 and rpt2-2 mutants. Furthermore, HBL-induced hypocotyl phototropism was enhanced in photl mutants and inhibited in the phot2 and rpt2-2 mutants. Our findings indicate that photl regulates the dissociation of NPH3 from the plasma membrane, whereas phot2 mediates the stabilization and relocation of NPH3 to the plasma membrane to acclimate to HBL.
