As the importance of strengthening the competency of managers who are in charge of cash collection and disbursement, and preparing for financial statements becomes more visible, this study examined the competency of middle-level managers of accounting department in general hospitals in Korea. Based on the literature, competency was measured by seven components: achievement and action, service, influence, management, cognition, individual effectiveness, and change management. Survey questionnaires included the respondents' perceived importance and performance of each of the seven components of competency. A total of 84 managers from 29 general hospitals responded to the survey between October 2015 and November 2015. Descriptive statistics, mean comparison (t-tests and ANOVAs), and multiple linear regression were conducted. The results of this study are as follows. Overall perceived importance of the competency was 4.16, while the performance was 3.87, and thus, the difference was 0.29. Among the seven components of the competency, cognition and change management had higher scores in terms of difference between the importance and performance. The regression analyses found that female managers had higher perceived importance and performance of competencies in achievement and action, and influence compared to male counterparts. In addition, participants in this study responded that main reasons for the gap between the perceived importance and performance are low compensation, lack of support, lack of knowledge, insufficient technical experience, excessive workload, and regulations. The results of this study can be used when designing capacity building training opportunities for the hospital accounting department. Also, the managers may evaluate themselves and look at the areas where they can narrow the gap between the perceived importance and performance of the competency that is required for today's leading managers.

Adults in their middle age are being held back by their roles through economic activities, but their rapid retirement and job sharing are adding to their anxiety. Also, it is very important to establish welfare policies for the elderly in the future because it can predict the economic situation in the old age through the economic activities of middle-aged adults. My study analyzed the 6th data of Kreis of the National Pension Research Institute's. The number of people studied is 2,552 employed people aged 40 or over 64 across the country. According to the analysis, there were more men than women. There were many high school graduates and 50s. There were many people who had spouses and who lived in the province. Wage workers represented 53.1% of the total. The lower the age, the higher the level of education, the higher the number of wage earners. Only 29% of standard workers and 30.8% of regular workers were employed. There were many economically unstable middle-aged adults. Economic instability in the middle age requires social attention because it can lead to poverty in old age. Therefore, measures should be taken to ensure stable jobs for middle-aged adults, whose spending increases more than their income.

The major purpose of the present research was to examine the effect of adolescents's perception of parents' marital relationship and attachment with their parents on school adjustment. This study also tried to investigate the inter-relationship among related variables, and the differences in the level of school adjustment according to adolescents' general characteristics. The participants were 355 middle and high school students who lived in Chollabuk-Do province. The major results of this research were as follows. First, there were significant differences in the level of school adjustment according to sex, age, and grade point. average That is, the level of school adjustment was higher for males, for older adolescents, and for those recording higher grade point, than for females, for younger, and for those recording relatively lower grade point. Second, parents' marital relationship was positively correlated with positive aspects of attachment with their parents(i.e., communication and trust), and with school adjustment. but negatively correlated with negative aspect of attachment(i.e., alienation from their parents). Finally, multiple regression analyses were performed to analyze the relative significance of the related variables influencing on school adjustment after controlling the effect of sex, age, and grade point. It was found that communication with fathers was the most powerful predictor of school adjustment, while attachment with mothers was not found to be a significant predictor of school adjustment.

Purpose: Adolescent obesity is a growing problem. This study examined the relationships between different types of physical activity and obesity in male and female middle and high school students. Methods: This study used the Korea National Health and Nutrition Examination Survey data of 2007. The study included 282 male and female middle and high school students who completed health survey questionnaires regarding physical activity. Physical activity was measured with vigorous and moderate activity and walking. BMI was used as an obesity indicator. Analyses were done using descriptive statistics, ANOVA, and chi-square test. In addition, multiple logistic regression were conducted to investigate the relationship between physical activity and obesity when adjusting for covariates. SAS/WIN 9.1 was used. Results: Boys spent more days in vigorous and moderate physical activity than girls (p for vigorous activity: <.001, for moderate activity: <.001). There was no significant difference in walking activity between boys and girls and between middle and high school students. Only days spent in vigorous activity was significantly higher in middle school student compared with high school students (p=.013). According to the relationship between physical activity and obesity, moderate physical activity was significantly related to BMI for high school boys (p=.041). However, when adjusting for age, sex, school, parental income, daily caloric intake, physical activity was not significantly related to obesity. Conclusions: The results showed that male and female middle and high school students spent not enough days in doing low moderate and vigorous physical activity. Thus, this strengthens the need to increase physical activity level in these populations. In spite of non-significant relationship between physical activity and obesity from multivariate analysis, increasing moderate physical activity for high school boy could be effective to prevent and manage obesity, since significant difference between moderate activity and obesity in this population.

The purpose of this study was to analysis the sanitary management performance based on HACCP system for school foodservice. This study was carried out from September 2008 until December 2008 and is targeted towards schools' dietitians that work at schools with school foodservice. The regional distribution of this research is as follows; 377 schools in Seoul, 648 schools in Gyeonggido, 160 schools in Kangwondo, 438 schools in Choongchungdo equaling 1,623 schools in total. When school foodservices were put through sanitation management achievement level analysis applied by the HACCP system, results displayed that management of temperature (3.96 points), time (4.08 points), and cross-contamination (4.07 points) were all below the average achievement level. HACCP system's achievement level based on the TQM showed that areas for strategy development, leadership, information and analysis had low achievement levels. Achievement levels for CCP are quality check, delivery/distribution process, sterilization/cleansing of food's contact surface. As a result of multiple regression analysis of the factors that influenced sanitation management achievement level of school foodservice HACCP system; sanitary job standard showed 35.6% and CCP achievement levels showed 26.8% explanatory rate. In particular, Kangwondo's number of foodservice provided to per cook was small. Also, the better the processing management was assessed, the higher the sanitary job standard achievement level became resulting to a explanatory rate of 39.5%. Elementary schools showed a higher explanatory rate of 37.0% than middle and high schools. CCP achievement levels in middle and high schools with self-operated foodservice had a 28.0% variable explanatory rate, which was the highest. The better the drainage system, leadership and assessments turned out to be, the higher the CCP achievement levels became. In summary, to revitalize HACCP system that is based on the TQM, it is considered that proper database of HACCP system for school foodservice's sanitation management be constructed and more emphasis should be put on strategy development to improve customers' satisfactory level. In addition, improvements in achievement levels of time, temperature, and cross-contamination for sanitary job standard and CCP achievement level are essential.
