Background: This study purposed to compare the difference on medical utilization and health expenditure of baby boomer generation by depression between gender. Methods: Korea Welfare Panel Survey 2016, provided by the Korea Institute for Health and Social Affairs, was used for the analysis. For the research, we used the two-part model, yes or no of use (part 1), and frequency of use (part 2) for medical utilization. The dependent variables are the whether or not to use of hospitalization services, outpatient services, length of stay, outpatient service visits, and health expenditure. And the independent variables are used as the predisposing (education, spouse presence), enabling (insurance type, private insurance, economic activity, income), and need (chronic disease, self-rated health, disability) factors in the Andersen behavior model. Depression was used as intervening variables. Structural equation model and multiple group analysis by gender were used. Results: There were differences in the medical care usage and cost between men and women in baby boomer. For men, mediating effects of depression were present at the hospitalization (yes/no), length of stay, and health expenditure. On the other hand, for women, the mediating effect of depression was found only at the outpatient visits. Specially, depression was working at the medical services by the different way between gender. The size of effect (multiple group analysis) was affected by significant differences between men and women. Conclusion: This study found that the mediating effect of depression is increased medical usage and health expenditure and the effect factors are different by gender. Therefore, it is necessary to establish a medical care policy considering the socio-economic characteristics of baby boomers.

Objective : Hyperhomocysteinemia has been proven to be an independent risk factor for stroke. The genetic mutation of methylenetetrahydrofolate reductase(MTHFR) elevates serum homocysteine level, but it still remains controversial whether the MTHFR gene mutation could be a predictor of ischemic stroke. Therefore, we studied if this genetic defect could cause ischemic stroke independently. Methods : We gathered ischemic stroke subjects and age, sex-matched controls. Age, gender, past medical history, smoking habit, serum homocysteine level, and the MTHFR genotype were recorded. General characteristics of ischemic stroke subjects were compared to the controls. We classified the stroke according to the related vessels(small and large artery infarction) and single lesion and multiple infraction. Relevant risk of the MTHFR genotype was evaluated in each stroke subtype with multiple logistic regression analysis. Results : When the controls were compared to the whole ischemic stroke, there was no specific difference except some medical histories. However, further analysis based on stroke subtypes showed important results. The small artery infarction group, multiple infraction group had significant odds ratio of the MTHFR TT genotype adjusted for age, gender, medical history and smoking habit. Conclusions : The MTHFR TT genotype is an independent risk factor for certain types of ischemic stroke, small artery infarction and multiple infarction.

Purpose. to help them find mental rest and improve school life adjustment by way of a fine art cure program. Methods. two primary schools in Gyeongsangnam-do were chosen where there are plenty of multiple-family kids. 13 children from the families between Korean husbands and foreign wives were divided into 2 groups: experimental group (7, C School), control group (6, H School). The two groups took the KSD (Kinetic School Draw), while the experimental group received a fine art cure program (40 minutes, once a week, 10 times in total). After the program, the KSD was given again to both groups. To prove the effects of this study, the picture projection test KSD was given before and after the experiment. For comparison and analysis, the changes in each individual's attitude, behavior, responses, and emotions were observed and recorded. Results. The fine art treatment program had some effects on the psychological rest of the elementary school children from multiple-culture families. In the pretest before the art cure program, the subjects shrank and cared a lot about others. According to the progress of the program, however, their worries and anxiety began to be gone. They had confidence through mental ease and self-respect. Therefore, the fine art cure program had a positive effect on the improvement of self-respect and sociality of multiple-culture family kids. Their school life was influenced by the newly-attained confidence, achievement, and peer relationship. Conclusions. This research is of some significance in that the fine art cure program was held to reveal its effects on the school life adjustment of the elementary school kids from multiple-culture families, especially because worries grow about the possibility of their maladjustment in the era of multiple-culture families. In addition, this program is expected to give some basic information about the development of programs to make friendly relations and smooth communication among the multiple-culture parents and teachers as well.

Objectives: To study symptom differentiation for yang deficiency and blood heat based on 117 psoriasis patients. Methods: Obtained frequency analysis (%), mean (%), and OR, CL(P-value) with prospective pre-post intervention design and multiple regression analysis. Results: There were no statistically significant differences as to sex, BMI, smoking and marital status, but there were statistically significant differences in variables of average age, family history, and alcohol consumption (P<0.05). There were no statistically significant differences in psoriasis symptoms as to initial age of onset, morbidity span, area of the initial onset, and the progression of psoriasis during the last three months of each patient. However, the type of psoriasis showed a statistically significant difference (p=0.011). While there were no statistically significant differences as to common cold, condition of psoriasis after recovering from the cold, skin condition, exercise, and seasonality, irregular perspiration showed significant difference (p<0.00). When confounding factors have been controlled the blood heat patient group as the comparison group, multiple regression analysis showed OR, CI(95%) of 1.06(0.31-3.63) for men, 0.28(0.08-1.06) for aged 30 to 49,0 and 0.18(0.04-0.80) for aged 50 and older. it was 0.06(0.01-0.7) for family history, 1.06(0.29-3.88) for drink alcohol, 19.90(2.53-156.7) for seasonality, and 10.28 (3.19-33.11) for perspiration problems. In these variables, Sex, age, smoking, and alcohol consumption showed no statistically significant results, but family history(p=0.049), seasonality(p=0.005), and irregular perspiration (p=0.017) were statistically significant. Conclusion: Family history, seasonality and irregular perspiration are the determining factors for yang deficiency and blood heat in psoriasis.

Purpose: This study was done to examine not only the relationships between body mass index (BMI), self-esteem, body image dissatisfaction (BID) and mental health, according to gender, but the mediating role of BID on mental health in relation to BMI and self-esteem among early adolescents. Methods: Data from 576 (296 boys and 280 girls) elementary school students in grades 5 to 6 were collected. A multiple-group path analysis was utilized to examine the relationships between BMI, self-esteem, BID and mental health by gender. Results: In the path analysis for all students, poor mental health was related directly to BID, while it was indirectly related to BMI and self-esteem. In the multiple-group path analysis of both genders, BID was found to have a significant direct and indirect effect on mental health for girls alone. Conclusion: The findings suggested that BID should be examined early to prevent poor mental health in early adolescent girls. This study helps to elucidate the role of early adolescent BID on mental health and provides insight for further prevention and intervention programs in school and community mental health settings.

Purpose: This study was conducted to investigate the influence of emotional labor, emotional dissonance, and burnout on nurse's turnover intention and examine the effect of job satisfaction on the relationships among emotional labor, emotional dissonance, burnout, and turnover intention. Methods: The sample consisted of 350 nurses recruited from 6 general hospitals in 2 cities in Korea. A multiple-group analysis was utilized. Data were analyzed using SPSS statistics 23 and AMOS 20. Results: In the path analysis, turnover intention was directly related to burnout in clinical nurses who had a high job satisfaction (${\beta}=.24$, p=.003), while it was indirectly related to emotional dissonance (${\beta}=.13$, p=.002). In the multiple-group path analysis, turnover intention was directly related to emotional dissonance (${\beta}=.18$, p=.033) and burnout (${\beta}=.26$, p=.002) for nurses with low job satisfaction. Conclusion: These results indicate that manuals and guidelines to alleviate the negative effects of emotional labor, emotional dissonance, and burnout, and to increase job satisfaction are strongly required to reduce turnover intention in nurses at the organizational level as well as at the individual level.
