For monitoring the fecal pollution at Nak-Dong River, one of the eutrophicated rivers, the differences between total coliforms (TC) and fecal coliforms (FC) using both of membrane filtration (MF)/MPN method, and also fecal streptococcus (FS) by MF-method was investigated. To evaluate the correlation between TC, FC, and FS statistical analyses were performed by using Minitab. And a part of the presumptive TC/FC and background colonies was purified and identified using API 20E kit (Biomeriux). As results, most (89%) of presumptive FC by MF was identified as Escherichia coli while only 14% (MPN) and 11% (MF) of TC were identified as E. coli. Furthermore, FC by MF was correlated significantly with other fecal indicators (TC/FS by MF and FC by MPN), while TC by MPN was not correlated with any other indicators. Thus, the detection of FC by MF-method may be the most reasonable for monitoring the fecal pollution.

Purpose: The purpose of this study was to determine the time and content of dietary education by analyzing the physiological indicators of hemodialysis patients during their first year and to present baseline data related to dietary education for patients on hemodialysis. Methods: For this retrospective study physiological indicators for 73 patients on hemodialysis were analyzed. Data included levels of potassium, phosphorus, albumin and the IDWG rate, and Kt/V during the first year after starting hemodialysis. Repeated-measure ANOVA was used for statistical analysis. Results: Serum levels of phosphorus (p<.006), albumin (p<.001) and the IDWG rate (p<.001) increased significantly in the 7 months from the start of hemodialysis. Conclusion: The results indicate that the period in which diet related educational intervention is necessary is before physiological changes, that is, after 6 months of dialysis. The contents for effective education should include phosphorus-limited and weight control dietary restrictions at 6 months.

Purpose: To compare the effects of the Interaction Model of Client Health Behavior (IMCHB)-based oral health program (OHP) and walking exercise program (WEP) on oral health behaviors, periodontal disease, physical activity, and psychological indicators (depression, stress, and quality of life) in pregnant women. Methods: A nonequivalent control group pretest-posttest design was adopted to compare the effects of a 12-week OHP and WEP on pregnant women (n=65). Pregnant women were randomly assigned to the oral health group (OHG; n=23), walking exercise group (WEG; n=21), or control group (CG; n=21). Data were analyzed by the ${\chi}^2-test$, Fisher's exact test, Scheffe test, and repeated measures ANOVA, using the Statistical Package for the Social Sciences for Windows (version 21.0). Results: The OHG and WEG showed significant improvements in oral health behaviors, periodontal disease, and psychological indicators as compared to the CG. The WEG showed significant improvement in physical activity as compared to the OHG and CG. Conclusion: These findings indicate that the IMCHB-based OHP and WEP were effective in improving periodontal disease, physical activity, and psychological indicators. However, further studies are needed to identify the positive effects of the OHP and WEP on birth outcomes.

Fisheries policies are diversifying, including welfare programs for fishermen, revitalization of earfish and villages, and support for the sixth industrialization of fishing villages. In response to these policy changes, the purpose of this study is to categorize the fishing village fraternity, which is a local community, a fishery production organization, and a basic unit of a fishing village, and compares the characteristics of each type A number of indicators were selected by collecting data on the Categorization and evaluation of fishing villages fraternity and the statistical geographic information service. A number of indicators were extracted as representative factor variables using the principal component analysis, and then cluster analysis was performed to categorize the fishing village fraternity. This study was the first to attempt a comprehensive approach to revitalize the fishing village economy by using not only demographic and social characteristics, industrial and economic characteristics, but also regional characteristics. The characteristics of each type of fishing village fraternity find its significance in that it provides basic information that can be used in policy decisions. In order to strengthen the sustainability of the fishing community in the future and contribute to the sustainable development at the national level, the development of sustainable fishing village fraternity development indicators and follow-up studies on fishing village regeneration strategies will be needed.

Objectives: The aim of this study was to characterize the community health indicators affecting standardized mortality rate of cerebrovascular diseases(CVD) and to identify the relationship between CVD mortality and community health indicators in Gangwon-do. Methods: The community health indicators included material deprivation index, medical resource, rates of road pavement and local tax. CVD mortality and the material deprivation index were calculated in the registered death data and the 2000 census which were obtained from the Korean National Statistics Office. The community health indicators were measured using 2001 statistical year book of Ganwon-do. Data were analyzed by using Excel 2003, SAS 9.1. CVD mortality and material deprivation index were visualized by Arcview 9.1. Results: CVD mortality varied by region and sex in Gangwon-do. The highest CVD mortality in male and female were noted at Goseong-gun, the lowest CVD mortality in male was at Yangyang-gun as it of female at Pyeongchang-gun. In Taebaek city where material deprivation index was also the highest; in Pyeongchang-gun was the lowest. Also the higher material deprivation index in some regions was the higher CVD mortality was. CVD mortality was not related with community health indicators. Conclusions: The results showed the regional difference of mortality of CVD among counties and cities in Gangwon-do. It is recommended that other community health indicators besides material deprivation index, road pavement rate, medical resources and local tax affecting CVD mortality need to be considered to improve the preventive strategies.

Purpose - This work aims to study the existing management process and methods of statistical evaluation of personnel mobility management, and propose improvement measures. This is particularly relevant in today's market economy because proper organization of personnel movement affects the availability and effective utilization of human resources in enterprises. Hence, it influences the volume, timely execution of work, equipment efficiency, and consequently the volume of production, its cost, profit, and other economic indicators. Research design, data, and methodology - We investigate the indicators that measure staff mobility, and their dependent consequences. Further, it analyses the factors influencing high staff turnover, which is a main indicator of staff mobility. Results - Measures for staff mobility development and prevention of turnover are proposed. Micom Systems is a sample case that has developed special programs to reduce staff turnover. Conclusions - Staff mobility leads to additional costs, significant loss of working time, and increase in defects. However, the advantages of staff mobility outweigh these negative factors. The role of staff mobility in a market economy cannot be overestimated.

To evaluate the biological water quality, diatom-based biological indices (DAIpo and TDI) were examined in the Sum-River and the Dal-stream. Having BOD concentrations below $2mg{\cdot}L^{-1}$ in most sites, water quality of both rivers was good. The DAIpo and TDI values ranged from 29.8 to 91.4 and from 38.7 to 93.0 respectively. From the biological water quality assessment, DAIpo and TDI for both rivers displayed fair to fairly poor water quality levels. However, the two indices showed more polluted conditions than expected from the BOD vlaues. In addition, DAIpo, having wider range of differences, appears to be more sensitive to the change in water quality when compared to TDI values. Statistical analysis using principal component analysis showed that Nitzschia palea and Diatoma vulgare might not be the appropriate indicators due to their low correlations with other indicators.
