Purpose: This study was done to examine the effects of using standardized patients in psychiatric nursing practical training for nursing college students. Methods: This research design was a quasi-experimental pre-and-post-test control and experimental group methodological comparison study. Forty-four (Exp.=23, Cont.=21) nursing college students in G city participated in the study. The experimental group received psychiatric nursing practical training using standardized patients, and the control group received traditional practice. Data were collected between October 1 and 15. 2011 through self-report structured questionnaires and were analyzed with the Kolmogorov-Smirnov test, x 2 -test, Fisher's exact test, and t-test using the SPSS/WIN 17.0 program. Results: After the treatment, there were significant differences in the level of motivation of transfer (t=1.71, p=.047), and learning self-efficacy (t=4.70, p<.001) between the experimental and control groups. The mean score per item for learning satisfaction was 4.28. Conclusion: The above findings indicate that psychiatric nursing practical training using standardized patients is a useful method for practical ability. Therefore, enhancement of performance ability related to practice can be done by developing psychiatric nursing practical training programs with various cases and content.

Purpose:In this study an examination was done of the effects of a team-based learning program on enhancement of communication competence for undergraduate nursing students in South Korea. Methods: A quasi-experimental method with a non-equivalent control group pre-and post-test design was used. Participants were 68 undergraduate nursing students recruited from two universities. The experimental group (n=35) received a 5-week team-based learning program on enhancement of communication competence, while the control group (n=33) received traditional lectures. Data were collected using self-report structured questionnaires before and after the intervention, and were analyzed using x 2 tests, Fisher's exact tests, and t-tests. Results: Compared to the control group, the experimental group reported significant positive changes in communication efficacy (t=2.58, p=.012), communication ability (t=12.01, p<.001), and learning satisfaction (t=2.11, p=.039). Conclusion: The findings indicate that this program is an effective intervention strategy to enhance communication competence for nursing students.

This study examined the mediating effect of psychological capital in the relationship between job stress and burnout of psychiatric nurses. The participants were 108 psychiatric nurses working in three psychiatric hospitals located in South Korea. Data were collected from 10 August to 15 September 2018 using self-report questionnaires. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson’s correlation coefficient, and multiple linear regression by IBM SPSS 24.0 program. In addition, a bootstrapping test using the SPSS PROCESS macro was conducted to test the statistical significance of the mediating effect. There was significant correlation between job stress, psychological capital, and burnout. Psychological capital showed partial mediating effects in the relationship between job stress and burnout. Job stress explained 29.7% of the variance in burnout, and the model including job stress and psychological capital explained 49.6% of the variance in burnout. The bootstrapping showed that psychological capital was a significant sub-parameter and decreased job stress and burnout (LLCI = −0.1442, ULCI = −0.3548). These findings suggest that psychiatric nurses’ burnout can be reduced by implementing various health care programs designed to increase psychological capital.

Purpose: The purpose of this study was to investigate factors predicting internet game addiction in higher grade elementary schoolers by gender in a city. Methods: The participants were 356 elementary school students who were in the 5th or 6th grade. Data were collected by structured questionnaires from March 15 to May 10 2011, and analyzed using descriptive statistics, x 2 -test, t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression with the SPSS/WIN 17.0 program. Results: Prevalence rate of internet game addiction for elementary school students was 10.1% (boys 17.2%, girls 2.4%). School adjustment showed a negative correlation with internet game addiction by gender (boys: r= -.36, p<.001, girls: r= -.21, p=.005). In boys, variables that predicted internet game addiction were academic activity, amount of time for internet gaming per week, conforming to school norms, and parents' child-rearing attitudes (54.0%). In girls, variables that predicted internet game addiction were academic activity and amount of time for internet gaming per day (33.0%). Conclusion: The findings from this study indicate the need to develope school adjustment enhance programs, particularly for boys, to prevent internet game addiction in higher grade elementary school students.

Purpose: This study was done to identify protective factors which predict internet game addition in middle school students using data mining decision tree analysis. Methods: The participants were 557 (Male=233, Female=324) middle school students from G city. Data were collected using structured questionnaires from March, 25 to May, 4, 2013, and analyzed using the descriptive analysis, t-test, ANOVA, decision tree, using SPSS 20.0 program. Results: The result of this research showed the prediction model for protective factors related to internet game addiction. Causative factors included gender, family support and father's attitude as the family protective factor, and planning ability as the personal protective factor. Level of accuracy of the decision tree was 70.6%. Conclusion: The different rules classified by the decision tree model in this study should contribute as baseline data for discovering informative knowledge and developing interventions tailored to gender and planning ability in internet game addiction.

Purpose:The purpose of the study was to investigate the psycho-social factors such as self-esteem, stress, and family support that affect the depression in pregnant women. Methods: The participants were 149 pregnant women who were seen at the urban G and M woman hospital. Data were collected using structured questionnaires from January 10 to May 20, 2011, and were analyzed using descriptive statistics, t-test, ANOVA, Pearson Correlation Coefficients, and Stepwise Multiple Regression with SPSS/WIN 17.0 program. Results: Mean age was 31 years, and 28.9% of the participants reported depression. Depression in the pregnant women showed a negative correlation with self-esteem (r=-.47, p<.001) and family support (r=-.38, p<.001), but a positive correlation with stress (r=.42, p<.001). In addition, variables that predicted depression in pregnant women were general health condition, stress, self-esteem, communication with husband, and planned pregnancy (39.0%). Conclusion: The findings from this study indicate the need to screen pregnant women for depression. There is also a need for programs to prevent depression in pregnant women and assess risk considering psycho-social factors.
