Background and purpose : Stroke is a leading cause of death in Korea. Early measures to prevent stroke are extremely important since it has no cure. Korean might have different risk factors since their dietary habits and socio-economical status differ from most western countries. However, the risk factors for stroke in Korea have not yet been identified. Moreover, the lifestyle of healthy Korean adults has not been investigated. In this study we investigate the lifestyle of healthy adults living in Seoul and rural areas and compare the lifestyles of the two. Methods : One hundred seventy one subjects were studied. Among the subjects studied, 128 were from Seoul, the other 43 were from the country area. The age of the subjects was limited to over 40 years. Blood pressure, fast blood sugar, and cholesterol were measured. The subjects' height, weight, body mass index, total body fat, skinfolds thickness of triceps, subscapular and abdomen were measured to determine obesity. Using a structured interview, we assessed : sodium intake, physical activity and exercise, consumption of vegetables, fat, fish and fruits. The results of the two groups were compared. Results : There were no statistical differences in age and education between the two groups of subjects. The mean age of the subjects were 66 years old. The subjects residing in rural areas had a higher intake of sodium(p<0.05), lower physical activity(P<0.05), and higher BMI and body fat (p<0.05) as compared to the subjects in Seoul. Subjects with hypertension were between 24% and 33% and the prevalence of hypertension was the highest when compared to the prevalence of DM or hypercholesterolemia. However, the prevalence of hypertension, DM, hypercholesterolemia, were not significantly different in these areas. Conclusion : Our results show that subjects living in rural areas eat more salty food, exercise less, and tend to be obese. The finding of this study lead to speculation that Korean living in rural areas have less information about the effects of diet on health than city dwellers do. General health and nutrition education programs aimed at the prevention of stroke and other such conditions for rural area Koreans may close the risk factor gap between rural and urban dwellers.

This study explores the effects of rural migrant characteristics and conjugal communication on life satisfaction of baby boomer rural migrants. A total of 205 Korean baby boomers, who are living in rural areas in the year of 2013 that had migrated from cities back in 2003 with their families, were analyzed. Their age ranged from 49 to 57 years. The statistical methods used for data analysis were descriptive statistics, t-test, and hierarchical regression analysis, with SPSS Win 20.0 program. The results of this study are summarized as follows: the reasons these baby boomers chose a rural lifestyle were 'for life after retirement,' 'because rural life is good,' 'for health reasons,' and 'for chosen profession.' The level of conjugal communication (M=3.69) and life satisfaction (M=3.23) were higher than average (M=3.0). The variables influencing life satisfaction of baby boomer rural migrants were 'increased property size,' 'better conjugal communication,' 'better health condition,' 'lower levels of money,' and 'length of time spent farming.' Furthermore, in terms of life satisfaction, the relative contributions of these variables are as follows: general characteristics 20%, rural migrant characteristics 10%, and the level of conjugal communication 6%. These results show that conjugal communication is a very important variable, as well as a rural migrant characteristic when it comes to life satisfaction of these baby boomers. Therefore, to improve life satisfaction of baby boomer rural migrants, support programs need to focus on both farming and conjugal relationships.

The purpose of this study was to examine the correlation between self-efficacy and self-care of hemodialysis patients. The subjects consisted of 140 hemodialysis patients who underwent hemodialysis at 2 university hospitals. The data were collected by questionnaires and chart review. The questinnaire used the self-efficacy tool developed by Kim Ju Hyune(1995) and the self-care tool developed by literature review and indepth open openended questions to 10 patients. Also, the questionnaire included physiologic data which collected through review of the patients' charts. The statistical analysis was used the SPSS program for frequency, mean, t-test, ANOVA and Pearson correlation. The results were as follows : 1. The mean score for general self-efficacy of hemodialysis patients was 3.103(1-4point) and there were significant differences according to percieved health. The mean score for specific self-efficacy of hemodialysis patients was 3.113 (1-4point) and there were significant differencies according to percieved health, side effects and complications which related hemodialysis. 2. The mean score for self-care of hemodialysis patients was 3.822(1-5point) and there were significant differencies according to marital status and economic level. 3. The relationship between general self-efficacy and self-care was a positive correlation(P＝.000). The relationship between specific self-efficacy and self-care was a positive correlation(P＝.000). In conclusion, this study revealed the level of self-efficacy and self-care, and the positive correlation between self-efficacy and self-care in hemodialysis patients. Therefore, intervention is needed to promote self-efficacy for self-care of hemodialysis patients. Considering the vulnerable self-care area same as checking blood pressure and weight, fluid restriction, social adjustment, exercise and rest, luther studies should develop self-efficacy promoting programs for self-care of hemodialysis patients.
