We study convergent influence on depression and its association with self-esteem, fatigue and psychosocial stress among General Hospital Administrative Staff(GHAS). The subjects were 201 randomly extracted GHAS from 9 general hospitals in J City, Data collection was carried out via a structured self-administered questionaries from Jul. 3rd, 2017 to Jul. 29th, 2017. Depression was positively correlated with three sub-domains of fatigue and psychosocial stress, and it was negatively correlated with self-esteem. With the analysis of covariance structure, depression was more influential on self-esteem than fatigue and psychosocial stress. The study found the higher fatigue and psychosocial stress, and the lower self-esteem tend to increase depression. The results indicate that the efforts, to increase self-esteem, and to decrease fatigue and psychosocial stress, are required to decrease the depression of GHAS. The results are expected to be useful for industrial health education and job management to decrease the depression of GHAS. In the following study, the analysis about convergent additional factors of influence on the depression of GHAS will be needed.

The purpose of this longitudinal study was to investigate confidence in core basic nursing skill each period of clinical practicum and discover the changes, depending on characteristics of periods. The data was collected for 94 nursing students attending a university located in J-do from Mar. 9 to Dec. 16 2016 for 4 times in total. For data analysis, the frequency analysis, descriptive statistics and paired t-test were used. The research findings showed that confidence in core basic nursing skill by each period of clinical practicum was lowest before clinical practicum in general but gradually increased depending on lapse of time and experience of clinical practicum. However, it decreased in all items after having first clinical practicum in the $2^{nd}$ semester, compared to after first clinical practicum in the $1^{st}$ semester. In addition, the difference of confidence in core basic nursing skill between clinical practicum periods was higher after the first clinical practicum in the $1^{st}$ semester and after clinical practicum at the end of school year, compared to before clinical practicum and after the first clinical practicum in the $2^{nd}$ semester respectively. Therefore, this study suggested that it's necessary to have efficient and systematic clinical practicum education strategy, reflecting the characteristics of periods in clinical practicum in order to improve the confidence in core basic nursing skill of nursing students.

This research derived sum of light (SOL) for Liaoning and Dandong, China, from DMSP OLS satellite images acquired at nighttime during 1992 to 2012 and investigated its potential association with economic status. The SOLs of Liaoning were found to be continuously increasing and higher than those of averages for the other provinces across the time period. The temporal pattern of SOLs would be interpreted to well reflect the economic status of this region based on real growth rate and average wage per capita. Nevertheless, the SOLs of Dandong were lower than the average of the other prefecture-level cities, which indicated the economic status of this city in China. Meanwhile, the average annual growth rate of SOLs for Dandong turned out to be increase for 1998~2007, compared with the previous years, and temporal patterns in the trade amount between North Korea and China and the export amount of North Korea to China were similar to those of SOLs in the same time period. The political association between South and North Koreas was improved with 'Sunshine Policy' during 1997~2007. Taking it into account, SOL is expected to be valuable spatial proxy index that could explain the geopolitcal and geoeconomic aspects of Dandong.

Population aging has been an increasing social issue and the elderly health has become one of the most urgent public attentions in Korea. The aims of this paper are to compare the subjective health status according to the personal characteristics, social networks, and daily leisure activities of the urban-rural elderly, and to analyze the influencing factors of their subjective health status. Using 2011 elderly survey data, ordered logit Model was established to extract influencing factors of the elderly health status. The results show that socioeconomic and demographic characteristics of individual as well as frequent social contacts and daily activities within neighborhood environments influence the level of health status of the elderly. The most significant factors affecting the elderly health are personal economic conditions such as the education achievement level and household income. The elderly who visit an elderly welfare center in Seoul has almost 1.82 times higher odds of increasing health status level than not to visit an elderly welfare center. This study may give some important policy implications of the elderly health promotion strategy in urban-rural communities.

Objectives: This study was conducted to investigate the effects of the sources of vitamin D (duration of exposure to sunlight, intake of major food sources for vitamin D or vitamin D supplements) on the serum 25-(OH) $D_3$ levels, and the physical growth of a child. Methods: Subjects were 296 children aged 1 to 5 years who visited S hospital located in Changwon City. Survey data collection was carried out by direct interview method, and the biochemical data were collected using hospital records. Results: The study subjects were divided into three groups according to their levels of serum 25-(OH) $D_3$ (deficient, relatively insufficient, sufficient) and their percentage were 48.3%, 44.3% and 7.4% respectively. The average concentration of serum 25-(OH) $D_3$ was $20.41{\pm}6.55ng/mL$, which was relatively insufficient. The average duration of exposure to sunlight was $58.86{\pm}49.18minutes/day$. A total score of vitamin D major food sources was 46.71 points (full marks 153), and the most frequently consumed food items were milk, eggs, and cheese. Thirty-four percent of the subjects took vitamin D supplements and their dose were $11.96{\mu}g/day$. Three vitamin D sources in sufficient group were higher than deficient or relatively insufficient group significantly. Intake of vitamin D supplements showed positive relation (+) and high explanation power ($R^2=0.288$) on serum 25-(OH) $D_3$ concentration, but intake of vitamin D major food sources (+) and the duration of exposure to sunlight (+) had a low explanation power ($R^2=0.068$). The relations between serum 25-(OH) $D_3$ concentration and physical growth (height and weight) were shown as negative (-), and their explanation powers were low as 7.3% and 5.9% respectively. Conclusions: This study results can be useful when discussing the intake standard of vitamin D and the effective intake method for children. In addition, it will be helpful to build the children's nutrition policy and to plan the nutrition education program to improve the vitamin D status in children.

Objectives: This study was performed to determine the relationships among health concern, health practice and health status of the disabled. Methods: A self-administered questionnaire survey was carried out for 1,662 disabled persons in Taegu city from April to July, 1997. Results: Health concern had a significant and positive relationship with health practice(p<0.05) and health practice also had a significant and positive relationship with self-rated health status(p<0.05) in men and women. To determine the structural model of the Health concern, health practice, health status and sociodemographic variables, the covariance structural analysis was used. In men, age, economic status, medical security type, educational level and type of disability had significant direct effects on Health concern(T>2.0). Educational level and type of disability had significant direct effects on health practice(T>2.0). And Economic status, medical security type and job status had significant direct effects on health status(T>2.0). In women, economic status and educational level had significant direct effects on Health concern(T>2.0). However there was no variable which had a significant direct effect on health practice. Job status had a significant direct effect or health status(T>2.0). In men and women, health practice was significantly increased with increasing health concern and the more health practice, the higher health status(T>2.0). Conclusions: It is recommended that the institutional approach which improve the economic status of the disabled with understanding their behavior and attitude should be established to increase health status, in addition, the health policy for encouraging the disabled, such as health education, consulting and health promotion program, should be done.

We evaluated the relationship between birth weight and mercury exposure levels in Seoul, Korea, by following a cohort of pregnant women and the outcomes of their pregnancies between 2001-2005. Eighty-five pregnant women were recruited into this study after obtaining informed consent. Samples were collected at delivery from normal pregnant women who were living in the city of Seoul, Korea. Mercury concentrations in 85 sets of maternal and cord blood samples were measured using a gold-amalgam collection method. We used multiple regression analysis to analyze the effect of mercury exposure on birth weight. The mean levels of total mercury concentrations were 5.41(ppb) in maternal blood of pregnant women and 3.58(ppb) in umbilical cord blood. The mean concentration of umbilical cord blood mercury exposures was higher than the level recommended by WHO. There was a significant correlation between maternal and cord blood mercury concentrations. Mercury concentrations of umbilical cord blood was associated with birth weight. In addition, after adjusting for potential confounding factors, we found that mercury exposure may reduce the birth weight. This study suggests that exposure to mercury concentration during pregnancy contributes to the risk of low birth weight. Therefore, prenatal and environmental education for various and possible sources of mercury exposure might be necessary for the good health of babies. The finding of this study supports the construction of national policy for environmental health management.

Objectives : The coverage of Korean National Health Insurance is limited to basic level. Korean government encourages private health insurance for covering medical securities. So, many studies examined the determinants of purchasing private health insurance. However, 11% of Korean population is older than 65 in 2011. Considering the elderly is important to establish a health policy. The aim of this study is to examine factors determining the purchase of private health insurance among middle-aged and elderly Korean adults. Methods : We used the second Korean Longitudinal Study of Ageing (KLoSA), selected 8,688 sample of the aged 47 or older for the analysis. KLoSA collected information on demographic characteristics, income, health- related factors. KLoSA data include in the number of outpatient, inpatient, oriental hospital visit, dental clinic visit for two years. Logistic regression was used to examine the relationship between the determinants of purchasing private health insurance and the factors which include age, gender, education, residential district, marital status, smoking, drinking, physical exercise, economic activity status, national health insurance type, income, the number of chronic disease, and the number of outpatient, inpatient, oriental hospital visit, dental clinic visit for two years. Results : People who were older, did not live in a city, had higher IADL, currently drunk alcohol, did exercise regularly and had chronic diseases more than three were inclined not to purchase private health insurance. Females, the married, well-educated, past & currently smokers, the employed, high income earners, national health insurers, metropolitan citizens and someone who got high MMSE were more likely to purchase private health insurance. The more people experienced outpatients, inpatients, dental clinics and Chinese medicine clinics, the more private health insurance was purchased. The elderly people over 75 had more private health insurance than the aged 65-74. The strongest factors for private health insurance is gender, and economic status such as income. Conclusion : In this study, we found healthy-high income people were more likely to purchase private health insurance. In contrast, unhealthy-low income and older people did not. The economic factors were strongly related with private health insurance in aged over 75. These mean inequality exists in the using private health insurance. Therefore, the government should consider vulnerable social group before expanding private health insurance.
