In this paper, we study the methodology for the measurement and integration of market risk and credit risk using Copula. We apply the methodology of Rosenberg, and Schuermann(2006) to the assets of pension system. Firstly we estimate dynamics of risk factors and their effects on investment returns, then use the estimated result to simulate future movement of risk factors and distribution of investment returns. Finally we measure integrated risk using integrated return distribution by Copula and simulated future investment return distributions. We found the integrated risk changing with the correlation of risks and investment weights of risks and confirmed the diversification effect of risks. This result is consistent when we use normal Copula and normal marginals, t-Copula and t(3) marginals, and normal Copula and non-parametric marginals. And in the case of non-parametric maginals, larger integrated risk is calculated. It means that use of non-parametric marginals is more conservative.

Purpose: The purpose of this study was to identify predictors of eating disorders in adolescents with type 1 diabetes, with the goal of providing data in support of nursing interventions to improve their health. Methods: A total of 136 adolescents aged 13-18 years with type 1 diabetes completed the Diabetes Eating Problem Survey-Revised, Rosenberg Self-Esteem Scale, and the Beck Depression Inventory-II, using structured self-reported questionnaires. The collected data were analyzed using the t-test, $x^2$ test, and binominal logistic regression with SPSS version 23.0 for Windows. Results: The prevalence of eating disorders in adolescents with type 1 diabetes was 39%. Four significant predictors of eating disorders were identified; absence of body satisfaction (odds ratio [OR]=3.87, 95% confidence interval [CI]=1.55~9.65), depression (OR=2.87, 95% CI=1.13~7.28), female gender (OR=2.67, 95% CI=1.09~6.54), and glycosylated hemoglobin type A1c levels (OR=1.47, 95% CI=1.10~1.97). Conclusion: In order to prevent eating disorders among adolescents with type 1 diabetes, programs for managing adolescents' depression and improving their body satisfaction should be developed. Futhermore, more attention should be directed towards programs aiming to prevent eating disorders in female adolescents.

Purpose: The aim of this study was to examine the effects of a music-based group reminiscence program on interpersonal relationships, self-esteem and depression in elderly people who are hospitalized. Methods: A quasi-experimental research was implemented, and a nonequivalent control group pre-posttest design was used. The participants were 52 elders who met the selection criteria and were assigned to the experimental group (26) and the control group (26). Both groups took the pre and posttest at the same time, and both groups received regular hospital care with the experimental group participating in the program for 12 sessions over six weeks. The instruments used in the study were, for interpersonal relationships, the Interpersonal Change Scale by Schlein and Guerney (1971), for self-esteem, the Self-Esteem Scale by Rosenberg (1965) and for depression, the Depression Inventory by Zung (1965). The collected data were analyzed with the SPSS 15.0 program. Results: Compared to the control group, the experimental group had significantly better interpersonal relationships and significantly higher self-esteem and less depression. Conclusion: The findings of the study suggest that a music-based group reminiscence program is effective in improving the interpersonal relationships, self-esteem and depression of hospitalized elders.

The purposes of this study were to investigate stress responses of senior high school students(examines) preparing for college entrance examination and to identify the relationship between stress responses and self-esteem. The subjects of this study were 261 senior high school students from three high schools located in three different Gu Seoul Korea. Data were collected from 19th to 27th march, 1998. Stress responses were measured by SOS (symptoms of stress) inventory and self- esteem was measured by Rosenberg's self-esteem scale. The data were analyzed with descriptive statistics, t-test, ANOVA and Pearson's correlation coefficient. The results were as follows : 1. The mean SOS score of subjects was 1.22 and that showed statistically significant according to gender difference (t=-6.00, P<0.0001) and father's occupations (F=3.10, P=0.006). 2. The mean self-esteem score was 2.77 and that showed statistically significant difference according to economic status(F=3.96, P=0.02) and father's occupations (F=2.71, P=0.01). 3. There was significant negative correlation between the mean SOS score and the mean self-esteem score(r=-0.31, P=0.0001). In conclusion, the examines had very high physiological and psychological stress responses and especially female showed higher stress responses than male. For this reason, school nurses are recommended (1)to develop appropriate stress management technique, (2) to provide more intensive care for health of female examines Nursing intervention should be developed for enhancing self-esteem of examines because self-esteem is negatively correlated with SOS.

Objectives : Psychological comorbidities are high in patients with obesity and are associated with a variety of medical and dietary problems. This study aims to examine the association between psychological factors and obesity. Methods : This study was performed in pre-menopausal obese($BMI{\geq}25kg/m^2$, waist circumference ${\geq}85cm$) women in Seoul, in 2008 (n=35). Every patient underwent the obesity treatment program. The program included dietary and exercise education, and abdominal mesotherapy for 6 weeks. Simple anthropometry including weight, BMI and Computed Tomography (CT) including Subcutaneous adipose tissue (SAT), Visceral adipose tissue (VAT) and Visceral adipose tissue/Subcutaneous adipose tissue ratio (VSR) were done. To assess psychological factors, the Rosenberg self-esteem scale (SES) questionnaire, Beck depression inventory (BDI) questionnaire and stress response inventory(SRI) questionnaire were administered. Results : 1. All of the obesity indicators (except VSR) decreased significantly after the obesity treatment program. 2. There was a significant relationship between self esteem (SES score) and visceral obesity (VAT and VSR) measured at the end of the program. 3. During the intervention, the more weight, BMI, and subcutaneous adipose tissue decreased, the more self-esteem (SES) increased. There was no relationship between depression (BDI) and obesity. And the change in stress response (SRI) was associated with the change of deep subcutaneous adipose tissue and total abdominal adipose tissue. Conclusions : This study proves that visceral obesity may contribute to low self-esteem, and there is a possibility that the other psychological factors could also be related with obesity in Korean obese women. Individualised antiobesity therapy may be required depending on the patient's psychological characteristics and weight loss could be helpful in order to treat psychological problem in obese patients.

This study was conducted to investigate the relationship among body image Perception, eating behavior and health status in young females. The survey was carried out by self-questionnaires for 293 female high school students(HS) and 164 female college students(CS) living in Daegu and suburbs of Daegu. For the perception of body image, 9-grade body figure drawings were used based on average Korean body size. EAT-26 and Rosenberg Self-Esteem Scale were used to measure the tendency of eating disorder and self-esteem. It appeared that 40.5% of the subjects were off the normal range of body weight; especially 34.2% of the subject were underweight. The subjects' perception about current body image was within normal range. Almost of all the subjects believed that the ideal body image was thinner than their own current body image, and they wanted to be thinner than their current body image. The change of eating behaviors related to weight control of CS was significantly higher than that of HS students. EAT-26 score, self-esteem score, and subjective health status score were no difference between groups. The cut-off point of the eating disorder in this study was equal to or greater than 20 in EAT-26 score. The rates of the eating disorder were very high as 9.6% of HS and 8.5% of CS. Eating disorder was positively correlated with BMI, current body image, dissatisfaction of body image and the change score of eating behavior. But eating disorder was negatively correlated with health status. From the results of this study, we suggested that one of causes related to the eating disorder behaviors in adolescent females was resulted from misperception about ideal body image. There is a great need to provide nutrition educations concerning appropriate perception of body image and weight control among adolescent females.

Objectives: This study aims to investigate the attitude toward smoking and knowledge on smoking, self-efficacy, and self-esteem among high school students, and examine the moderate effects of gender on the differences in those variables between smoking and non-smoking students. As the result of investigation, it would suggest useful information for those who want to provide interventions of smoking prevention and smoking cessation to adolescents. Methods: Participants were 1,117 high school students (511 males, 584 females), whose mean age was 16.38 (SD=.87). To identify whether participants were smoking or not, bogus-pipeline was used. The data was collected with questionnaire include Smoking Attitude Inventory, General Self-Efficacy Scale, and Rosenberg's Self-Esteem Scale. A Pearson chi-square test and 2-way MANOVAs were performed with SPSS 11.5 for Windows. Results: With bogus-pipeline, one hundred thirty five (26.0%) of male students and 125(21.4%) of female students reported as they were smoking, while 115(22.2%) of male students and 78(13.3%) of female students reported as they were smoking at unidentified survey which was performed one week before bogus-pipeline. Results revealed that students who smoked had more positive attitude toward smoking and more knowledge on smoking than those who didn't smoke. Difference in knowledge on smoking between smoking and non-smoking students only existed in female students. Female students who smoked had lower self-esteem than female students who didn't smoke, but this difference didn't exist in male students. Conclusion: With the results of this study, it is considered smoking rates of adolescents surveyed with unidentified self-report questionnaires as underestimated. Health practitioners might consider female smokers' attitude toward and knowledge on smoking and self-esteem, especially for high school students. Despite of limitation of this study, it might help those who want to prevent initiation of smoking and give up smoking in adolescence.
