Background: Hong Kong's construction industry currently faces a manpower crisis. Blue-collar workers are a disadvantaged group and suffer higher levels of chronic diseases, for example, cancer, than the wider population. Cancer risk factors are likely to cluster together. We documented prevalence of cancer-associated lifestyle risk behaviors and their correlates among Hong Kong construction workers. Methods: Data were collected from workers at 37 railway-related construction worksites throughout Hong Kong during May 2014. Tobacco use, alcohol consumption, unbalanced nutrition intake, and physical inactivity were included in the analysis. Latent class analysis and multivariable logistic regression were performed to identify the patterns of risk behaviors related to cancer, as well as their impact factors among construction workers in Hong Kong. Results: Overall, 1,443 workers participated. Latent class analysis identified four different behavioral classes in the sample. Fully adjusted multiple logistic regression identified age, gender, years of Hong Kong residency, ethnicity, educational level, and living status differentiated behavioral classes. Conclusion: High levels of lifestyle-related cancer-risk behaviors were found in most of the Hong Kong construction workers studied. The present study contributes to understanding how cancer-related lifestyle risk behaviors cluster among construction workers and relative impact factors of risk behaviors. It is essential to tailor health behavior interventions focused on multiple risk behaviors among different groups for further enlarging the effects on cancer prevention.

This paper explores the effects of the 1997 economic crisis on the pattern of socioeconomic differentials in fertility. Based on analysis of data from the 2003 Korea National Fertility Survey, this study focuses on recent changes in the level of fertility according to socioeconomic status of the couple including educational level, occupation, working status, income, etc. Results reveal that the level of fertility of those with the highest education, most prestigious occupation, and employer status are higher than those of the next group in the socioeconomic hierarchy. These findings imply that the straight line inverse pattern of socioeconomic differentials in CEB yielded to a reversed J-shaped curve. However, recent differentials of fertility after the economic crisis were found to contrast with the pattern above. Decrease in fertility has been most drastic among those with a high level of fertility, and relatively slow for those with a low level of fertility. The level of recent fertility turns out to be highest among those with upper-middle socioeconomic status, followed by those with the highest socioeconomic status and those with the lowest status. Policy implications and some comments on current population policies of the Korean government are also presented in this paper.

The purpose of this study was to examine dental hygienist's emotional labor, burnout and turnover intention. Data were collected from 215 dental hygienists working at hospitals and dental clinics through self-administered questionnaire, and analyzed by statistical analysis using t-test, ANOVA, Pearson's correlation coefficient and multiple regression analysis. The main findings of the study are as follows: the higher the educational level of dental hygienists, and the bigger the size of dental institutions they work, and the lower the monthly income of dental hygienists, the higher the level of emotional labor of dental hygienists. Burnout was influenced on emotional labor and turnover intention. Emotion labor and turnover intention were influenced on burnout. Tenure under 5 years, five-day workweek (non), emotional burnout were found to have significant effects on the turnover intention. Dental hygienists were doing relatively high emotional labor, and it influences his burnout experience and turnover intention. It is needed to make the workplace better environment which can secure appropriate work load and rewards, and education programs etc.

Currently, patrol officers dispatched are required to work in pairs, and are assigned individual duties. However, despite these rules, there are still inappropriate combat education centered around dangerous weapons and arresting technique training being taught in the police system. The human rights problems resulting from excessive responses, the damages done to the patrol officers due to insufficient responses, and the judicial issues that many officers who have justly arrested face, reveal the ultimate problem of the decrease in reliability of the police. Considering this problem, there is a need for change in the current training system. Specifically, in the current dispatch rule, assignment of individual duties, and training methods, realistic improvements must be made. Having understood the arrest technique training problem and reviewed case studies of the police training in South Korea and other countries, I plan to analyze the effects of implementing a realistic and professional training system, and propose a systemic solution according to the results. By effectively discussing the various issues of the proposed training and police education, I intend to propose a realistic teamwork training for paired patrol officers, enabling them to work well together in practice and theory, hence increasing the effectiveness in crime situation.

This study examines the sustaining power of program effects of Reading Comprehensive Strategy Program, for underachieving gifted students in middle schools, which was developed and applied by Choi(2015). The study was a kind of follow up study of Choi(2015) as this study traced and collected all data from the same samples that Choi(2015) used since Choi(2015) stopped his program and data collection from 31 participants for 9 to 12 months. As the results, Among 11 subjects, who overcome underachievement through Choi(2015)'s Reading Comprehensive Strategy Program, 5 subjects could consistently maintained their performance level. However, 3 subjects could not maintain their performance and went back to the underachieving level, and another 3 showed instability as they went up and down around the border line. And among 20 subjects, who could not help the underachieving level through Choi(2015)'s program, 5 subjects could reach the achieving level. But 15 subjects still remained in their underachieving level. In conclusion, we may say that at least 16.1%(5 among 31) of underachieving gifed students could overcome their underachiving issue by Choi(2015)'s program even in the most pessimistic view, and 51.6%(16 amoung 3) in the most optimistic view. After all, at least about 50% cases could not be explained only by cognitive factors such as absence of reading comprehensive strategy. We suggest that we should handle the underachieving issues of gifted students by more comprehensive approaches.

The Tandong-cheon stream is a 7.4 km long small urban stream that passes through Daeduk Science Town in Daejeon Korea. Despite the stream has great potential as an educational and recreational site due to its central location in the science town and science museums nearby, environmental aspect especially for water quality has not been evaluated properly. Through field survey, major pollution sources of the stream were identified and effect of water quality improvement alternatives were evaluated using a QUAL2K water quality model for the stream. The study indicated that controlling major pollution sources of the stream alone may not be sufficient for reaching the water quality target. Therefore, additional pollution control methods are necessary. We applied the developed model to evaluate the effects of a constructed wetland on the terrace land, and analyzed whether the water quality target can be met at the outlet of the stream. It is expected that this study would provide a good reference for environmentally sound management of small urban streams in Korea.
