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.

Objective: Pain is very common in the elderly, so there is a high prevalence of analgesic use among this population. The purpose of this study was to assess patterns of analgesic use and evaluate factors associated with analgesic use in elderly patients. Method: The subjects of this study were patients over 65 years old hospitalized in a teaching hospital located in Chuncheon-si, Korea between January 1, 2014 and March 31, 2014. Data collection regarding analgesic prescriptions and baseline characteristics was conducted using computerized hospital database by medical information team. Logistic regression analysis was used to identify factors related to analgesic use. Results: A total of 2,394 patients were finally included. Among these patients, 700 (29.2%) took analgesics; 521 (74.4%) out of these 700 patients were received opioid analgesics and 179 (25.6%) were received only non-opioid analgesics. The most frequently prescribed opioid analgesic was pethidine (45.7%), and the most frequently prescribed non-opioid analgesic was acetaminophen (44.1%). Fracture was associated with increased odds of opioid analgesic prescriptions (OR = 2.766, 95% CI = 2.019-3.790, p < 0.001) and any analgesic prescriptions (OR = 2.394, 95% CI = 1.766-3.244, p < 0.001). Stroke or cerebral infarction was associated with decreased odds of opioid analgesic prescriptions (OR = 0.636, 95% CI = 0.471-0.858, p = 0.003). Conclusion: A significant proportion of hospitalized elderly patients use analgesics. Health care professionals should consider factors associated with analgesic use in this population to improve pain management.

Objectives: This study aims to investigate the estimated proportion for influenza vaccination and to identify factors associated with influenza vaccination in Korean adults aged 50 and older with asthma. Methods: Data from 2010-2015 Community Health Survey(n=23,662) was used. A chi-square test was performed to investigate the estimated proportion for influenza vaccination, and a multiple logistic regression analysis was used to identify the factors associated with self-reported influenza vaccination. Results: In men, 42.3-49.5% of asthma patients 50-64 years of age, and 78.5-90.2% of elderly (over 65 years of age) asthma patients received influenza vaccination. In women, 49.7-61.9% of asthma patients 50-64 years of age, and 82.7-89.7% of elderly asthma patients received influenza vaccination(p<0.0001). Low education level, non-smoking, non-drinking, hypertension, diabetes and use of public center were related to high influenza vaccination in 50-64 years old men with asthma. Low education level, non-smoking, bad health status, hypertension, diabetes and use of public center were related to high influenza vaccination in 50-64 years old women with asthma. Non-smoking and use of public center were related to high influenza vaccination in over 65 years old men with asthma. White-collar jobs, smoking, absence of hypertension and use of public center were related to low influenza vaccination in over 65 years old women with asthma. Conclusions: Influenza vaccination remains relatively low in asthma patients 50-64 years of age. It is necessary to recommend vaccination to asthma patients, provide them with information, and devise other strategies to improve vaccination.

Purpose: Non-Suicidal Self-Injury (NSSI), a highly prevalent behavior in adolescents, refers to the direct destruction of one's body tissue without suicidal intent. To date, the prevalence of adolescent self-injury in South Korea and its associated factors remain unknown. This study aims to determine the prevalence of self-injury in Korean adolescents as well as its associated factors. Methods: We assessed 717 middle school students by means of an anonymous self-report survey. Information about demographic characteristics, lifestyle, anxiety and depression, self-esteem, and parenting behavior was obtained. Data were analyzed using $x^2$ test, t-test and multiple logistic regression. Results: NSSI was reported by 8.8% of respondents. Univariate analyses showed associations of exposure to alcohol use, anxiety, depression, self-esteem, and parenting methods with self-injury. In multiple analyses, alcohol use, anxiety, and parental abuse were associated with lifetime self-injury. Conclusion: The rate of NSSI in the South Korea was found to be lower than those of other countries. As our study suggests that alcohol use, anxiety, and parental abuse are associated with lifetime self-injury, health care providers at school should take these factors into account when developing prevention and intervention programs for adolescents.

The purpose of this study was to investigate the actual state and problems of outlet stores. And examine store attributes shopping orientations information sources according to demographic characteristics for outlet store patronage group. The questionnaires were administered to 400 women living in Taegu. The data were analyzed by using Frequency Percentage Factor Analysis MANOVA. The results of the study were as follows; 1) Outlet stores in Taegu area were run as the type of agency and dealt in most brands of their own companies, There were plenty of as-sortment and merchandise. The discount rate was 50-60% Stores' locations were scattered which made shopping environment incon-venient. 2) The store attributes were composed of five factors such as fashion & products diver-sity service store reputation convenience and price. Shopping orientation were com-posed of six factors such as self-confidence for shopping brand oriented store loyalty & near-store oriented economical self-assumed shopping and difficulty of choice. Information sources were composed of four factors such as print media & display personal information advertising and store visit. 3) There were significant differences be-tween patronage group and non-patronage group in store reputation service fashion & products diversity. Patronage group is more satisfied with these three factors. There were significant differences between patronage group and non-patronage group in brand oriented and economical Non-patronage group was more brand oriented and patronage group was more economical. There were significant difference between patronage group and non-patronage group in print dedia & display factos. Non-patronage group made more use of print media& display than patronage group as information sources. There were significant differences between patronage group non-patrpnage group in age marital status and levle of education.

The purpose of this study was to identify the characteristics of coping behaviors of non-professional working mothers and find out the individual and situational factors which affect the degree of coping behaviors. For this research, the working mothers in non-professional job with children under age 18 answered the structured questionaire. The findings were as follows. First, the degree of coping behaviors was rather high in multiple role management strategies, strengthening family system and positive thinking, but rather low in housework socialization and role reduction/standard adjustment. Second, the effect of associated variables were different according to the subcategories of coping behaviors. So we conclude that, the coping behaviors of the non-professional working mothers were different from those of professional working mothers in some aspects, althought they have much similarities. The different aspects were 1) The relationship of family income and the degree of housework socialization was more evident. 2) The work-related variables did not affect the coping process significantly because of the conservative sex-role attitued of them. Second, non-professional working mothers should use coping behaviors such as housework socialization, role reduction/standard adjustment more for the more effective management of the role strain. Third, the attitude of occupational and parental role was one of the most important factors in using the role strain coping behaviors. And such an unconscious use of the coping behavior won't be helpful in the feeling of control over environment including role strain and active coping of working mothers.

The purpose of this study is to identify (1) the attitudes of seniors toward library digitalization, (2) factors that lead them to use digital information in libraries, and (3) factors that hinder or prevent them from using digital information in libraries. As a result of conducting 1:1 in-depth interviews with 20 senior users of the National Library of Korea, the majority of seniors had a favorable attitude toward library digitalization. 'Librarian' and 'vision and font size' were found to be the most important factors for seniors' use of digital information. These two factors are factors that enable the use of digital information, but they are also factors that prevent or hinder the use of digital information. In addition, factors for the use of digital information include 'characteristics of the content' and 'convenience', factors for non-use include 'attitude and psychological factors' and 'physical properties of books', and hindering factors include 'website usability issues'.

This study takes a holistic approach to understand the diffusion of IPTV services by combining the adoption-diffusion model and the use-diffusion model of innovation. IPTV service, a leading digital converged application coupling media content with telecommunications, has been recently launched commercially in Korea. We created a structural model of adoption-diffusion, using the perceived easeof-use and usefulness of TAM(Technology Acceptance Model) as mediating variables, and a structural model of use-diffusion, with the rate of use and the variety of use as mediating variables. To empirically analyze these models, non-users of IPTV were surveyed using the adoption-diffusion model to identify factors influencing their intention to subscribe to the service. Meanwhile, users of IPTV were surveyed using the use-diffusion model to determine the factors that influence their satisfaction with the service and their intention to re-use it. Under the adoption-diffusion model, we found that trialability, household innovativeness and perceived risk were the determinants of user satisfaction with IPTV, and perceived ease-of-use, the mediating factors. Under the use-diffusion model, complementarity and communication were shown to be the determinants of users' satisfaction with IPTV, and variety of use, the mediating factor. We also found that consumers' intention to re-use IPTV was strongly influenced by its relative advantage and perceived risk.
