Self-esteem as a Moderator of the Effects of Happiness, Depression, and Hostility on Suicidality Among Early Adolescents in Korea / 예방의학회지

OBJECTIVES: The purpose of this study was to investigate the role of self-esteem as a moderator of the factors influencing suicidality among middle-schoolers. METHODS: Moderated multiple regression analysis was applied to assess the influence of happiness, depression, and hostility on suicidality and to determine the degree to which self-esteem served as a moderator of those relationships. Data were collected from 268 students at a middle school in Busan, Korea, using a self-administered structured questionnaire. RESULTS: Happiness, depression, and hostility had significant direct effects on suicidality. Self-esteem showed no direct effect, but had a significant moderating effect on the relationship between hostility and suicidal behavior. CONCLUSIONS: These results suggest that various interventions, such as counseling programs, should be designed to alleviate hostility and depression and to enhance happiness and self-esteem among early adolescents.

Affecting Factors on the Willingness to Platelet Apheresis / 대한수혈학회지

BACKGROUND: The purpose of this study is to empirically find out the affecting factors on the willingness to platelet apheresis. METHODS: Data were collected from 505 platelet apheresis donors and college students of major cities in Korea using the self-administered questionnaire. RESULTS: First, the level of positive cognition and affectivity to platelet apheresis donation and satisfaction for service during donation process among platelet apheresis donors were significantly higher than that among students only experiencing whole blood donation and students never experiencing blood donation. Second, valence for external and internal reward and knowledge of platelet apheresis among platelet apheresis donors were significantly higher than that among students only experiencing whole blood donation and students never experiencing blood donation. Third, platelet apheresis donors and students experiencing whole blood donation were more sound in character and more active in volunteer works, and had healthier behavior than students never experiencing blood donation. Fourth, the results of multiple regression analysis showed a statistically significant positive relationship between the willingness to platelet apheresis and valence for internal and external reward, satisfaction for service during donation process, and health behavior. CONCLUSIONS: These findings suggest that strategy for effective public relation and improvement of blood donor satisfaction should be developed in order to enhance willingness to platelet apheresis.

Geographic variations in tonsillectomy and adnoidectomy (T & A) and appendectomy in Korea / 예방의학회지

The objectives of this study are two-fold : to identify geographic variations in the rate of tonsillectomy and adenoidectomy(T and A) and appendectomy and analyze the socioeconomic variables and health resources which affect geographic variation in the rate. The nationwide three month's cases of the two surgical procedures in 1991 are obtained from the record of the National Federation of Medical Insurance. The analysis shows two to ten-fold variations in the regional rates for the performance of two common procedures such as T and A and appendectomy. T and A shows a bigger regional variations than appendectomy. As a result of multiple regression, the factor of bed supply has been found significant for the dependent variable of the rate of T and A. The findings of large variations in the rate of surgical procedures throughout the country would have important implications for allocating scarce resources and managing quality of care. Further analysis is needed for the elaboration of the above implications.
