This study was designed to investigate the differences in the mediation effects of cognitive emotion-regulation in the relationships between family stress and marital satisfaction of middle-aged husbands and wives. The data were underwent through the SPSS 19. Win for frequency, paired-t-test, multiple regression analysis, and for the further analysis of hiearchical multiple regression and the analysis for the mediation effect proposed by Baron & Kenny(1996) and Sobel test(Sobel, 1982). The results were as follows. First, hiearchical multiple regression analysis showed that education level, couples' problems, replanning strategies were proved to be significant for the marital satisfaction of the husbands, while age, couples' problems, acceptance strategies were significant for the marital satisfaction of the wives.

Objectives : QTc prolongation due to antipsychotics is of major concern because it may lead to fatal ventricular arrhythmia such as torsade de pointes. However, few studies have been conducted on QTc prolongation due to antipsychotics, especially in South Korea. This study aimed to investigate how demographic and clinical variables affect QTc interval in patients with schizophrenia. Methods : By retrospectively reviewing medical records, we assessed QTc interval, demographic data and clinical features of 441 (175 males) patients with schizophrenia who admitted to the psychiatric ward of a general hospital. To explore the predictive factors for QTc interval, hierarchical regression analysis was performed with QTc interval as the dependent variable. Results : The mean QTc interval was 417.2±28.4 ms. In the hierarchical regression analysis, the use of short-acting antipsychotic injection was the strongest predictor of the QTc prolongation. Conclusions : This study demonstrated that the use of short-acting antipsychotic injection may affect QTc prolongation in patients with schizophrenia. This result suggests that more attention should be paid to the use of short-acting antipsychotic injection in the treatment of schizophrenia.

The purpose of this study was to explore the mediating effect of emotional dysregulation on the relationship between the specific domains of self-esteem and aggression. Three questionnaire were administered to 287 individuals and the multiple regression analyses and Baron and Kenny's hierarchical regression analyses were used. The result shows that social and objective ability and positive character had significant influence on aggression, while impulse control difficulties, lack of emotional clarity and limited access to emotion regulation strategies largely contributed to aggression. Moreover, emotional dysregulation functioned as a significant mediator variable for explaining the link between self-esteem and aggression. Impulse control difficulties have fully mediated positive personality and hostility, limited access to emotion regulation has partially mediated social and objective ability and hostility, respectively.

A total 300 students of middle and high school located in Chungcheongbuk-do completed the questionnaires to assess school stress, anger expression styles, and interpersonal problem during September to October, 2015 and 261 data were used in this report. Using multiple and hierarchical regression analysis, the results indicated that school stress, anger-in and anger-out significantly contributed to interpersonal problem. The interaction effect of school stress and anger expression styles were not significant. But anger-out significantly moderated the impact of school stress on domineering/controlling of interpersonal problem.
