This study examined the influences of parent-child conflict and conflict resolution on behavior problems experienced in early adolescence by both boys and girls, and investigated whether conflict resolution had any moderating effects upon the relation between parent-child conflict and these behavior problems. The participants of this study were 397 first and second graders (193 boys and 204 girls) from three middle schools located in Seoul and Gyoung-gi province. To measure the research variables, the Korean-Youth Self Report by Oh et al. (2010), the short version of Conflict Behavior Questionnaire (Homes, 2012), and the Thomas Kilman Conflict Mode Instrument (Cha & Cheon, 2011) were used. The data were analyzed by means of descriptive statistics, t-test, multiple regression analysis, and hierarchical regression analysis. The results indicated that both for boys and girls, the level of parent-child conflict increased the levels of both externalizing and internalizing behavior problems whereas conflict resolution had no significant effect on behavior problems. In addition, in the case of boys only, conflict resolution moderated the effect of father-child conflict on internalizing behavior problems.

Purpose: This study analyzes the effects of smoking behaviors of women of reproductive ages in terms of maternal conditions and conditions arising during the perinatal period in Korea. Methods: We used the National Health Insurance Corporation's medical panel data. Subjects included 382 individuals suffering from maternal conditions and conditions arising during the perinatal period from 2013 to 2014. A t-test was used to analyze the individual differences between maternal conditions and conditions arising during the perinatal period-A hierarchical regression analysis was performed in two steps to measure the effects of smoking behaviors on diseases. Results: The amount and duration of smoking are significant factors causing maternal conditions and conditions arising during the perinatal period. In the regression analysis, the explanatory power of model was significantly increased by adding smoking behavior to the maternal conditions and conditions arising during the perinatal period. Smoking behavior during pregnancy displayed a significant influence on diseases. Conclusion: Results of this study showed that the effects of smoking behavior on maternal conditions and conditions arising during the perinatal period were significant. Therefore it is necessary to develop a smoking cessation education program for pregnant women in Korea.

Purpose: We investigated the relationship between patient safety culture and safety care activity, and identified factors for safety care activity of entry-level nurses. Methods: The subjects of the study were 204 entry-level nurses working at five general and advanced hospitals with over 500 beds located in C and D City. The data were analyzed using descriptive analysis, t-test, ANOVA, Pearson's correlation and hierarchical multiple regression with SPSS/WIN 18.0 program. Results: Perception of patient safety culture had significant correlations with safety care activity. Multiple regression analysis showed that demographic variables of quality of nursing on patient safety and health state of entry-level nurses affected safety care activity. In addition, patient safety culture in ward and communication affected safety care activity. These factors explained 38% of variance. Conclusion: Based on the results of the study, patient safety culture promotion strategies to facilitate supportive work environment and effective communication are needed.

Purpose: Optimism is an important psychological variable that functions positively in stress adaptation process. The purpose of this study was to identify either a mediating or moderating effect of optimism in the relationship between stress and well-being among mothers of children with diabetes mellitus. Methods: A sample of 109 mothers of children with diabetes mellitus was recruited in a tertiary hospital in B city and they completed self-reported questionnaires. Multiple regression analysis models were used to test the mediating and moderating effects of optimism in the relationship between stress and well-being. Results: The results of the multiple and hierarchical regression analysis showed that the role of optimism was examined a partial mediator of the relation between stress and well-being, not a moderator. Increased stress was associated with decreasing optimism and well-being, and increased optimism predicted increased well-being among mothers of children with diabetes mellitus. Conclusion: Optimism is more likely to play a role as mediator, rather than as a moderator. This finding suggests the importance of optimism in improving the well-being of mothers of children with diabetes mellitus.

The purpose of this study is to find determinants for service mind and skills of hospital employees to seek ways to improve the service level of hospitals. The past studies focused on the perspectives of customers in finding the solutions for service improvement. However, the existing approach failed in delving into the whole picture of service system. The behind operation of service system(e.g., selection and training of employees, support system) needs to be examined to have a balanced solution of service improvement. The personal characteristics, organizational characteristics, and customer experience were considered as the independent variables in predicting service mind and skills. The data collected in this study was gathered through questionnaire survey with 291 employees in five hospitals - from Sept. 10 to Oct. 16 in 2004. The results are as follows. 1. The regression analysis showed that job satisfaction and service commitment of organization were statistically significant in predicting service mind and skills. 2. The hierarchical regression analysis showed that the effect of hospital type on service mind was explained by service commitment of organization.

Purpose : This study aimed to identify the moderating and mediating effects of resilience on the relationship between role conflict and job satisfaction among nurses working in a comprehensive nursing care service ward. Methods : Participants were 130 comprehensive nursing care service ward nurses from four hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and hierarchical multiple regression analysis, using SPSS 25.0. The mediating effect of resilience on the relationship between role conflict and job satisfaction was analyzed using multiple regression analysis according to Baron and Kenny's procedure. Results : Statistically significant negative correlations were found between role conflict and resilience (r=-.25, p<.007) and between role conflict and job satisfaction (r=-.38, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.54, p<.001). A partial mediating effect of resilience was found between role conflict and job satisfaction (Z=-2.53, p=.012) but no moderating effect was found. Conclusion : To improve the job satisfaction of comprehensive nursing care service ward nurses, interventions for alleviating role conflict and improving resilience as well as evaluations of the two variables are necessary.

After experiencing school closures and online learning caused by COVID-19, the important role of school education was reinforced. Elementary school is the foundation of life and allows students to develop both social and academic skills. The purpose of this study was to examine the mediational role of Self-Regulatory Skills (SRS) on the relationship between Maternal Parenting Attitude (MPA) and School Adjustment (SA) of elementary school students. A total of 99 students enrolled in an international school in Seoul, Korea from grades 3 to 6 participated in this study. Data were analyzed through Independent Sample T-Test, one way ANOVA, Multiple Regression Analysis, and Hierarchical Regression Analysis using the SPSS 23.0. The findings of the study were as follows. First, there is a difference between genders and among grades. Second, only acceptance was significantly related to school adjustment. Third, acceptance, strict control, and accepted control are significantly related to SRS. Fourth, Self-Regulatory Skills (Sustained Attention) fully mediate the relationship between Maternal Parenting Attitude (Acceptance) and School Adjustment (Academic Attitude/ Rule compliance). Educational implications for understanding the role of parenting attitude and future directions are discussed.
