Purpose: This study aimed to examine the effects of a public health home care simulation for frail older adults the clinical practice skills, communication skills, critical thinking, and learner satisfaction of nursing students. Methods: A quasi-experimental design was employed with 82 fourth-year nursing students from two universities. All students received training on topics related to the public health home care simulation for frail older adults. The experimental group participated in a role-play simulation, while the control group engaged in a Nursing Lab virtual simulation. the WIN SPSS 25.0 program provided data analysis using chi-square tests, independent t-test, and paired t-test. Results: Both groups demonstrated significant improvement in clinical performance, and no significant difference was found between groups (t=0.66, p=.515). Although communication skills significantly improved in the experimental group (t=3.03, p=.004), there was no significant change in the control group (t=-0.75, p=.459). A significant difference in communication skill changes was observed between groups (t=2.73, p=.008). Critical thinking skills were significantly improved in both groups, and no between-group difference was found (t=-1.51, p=.136). There was no significant difference in level of program satisfaction between the two groups (t=0.69, p=.492). Conclusion: The results of this study suggest the necessity of developing a public health center home-visit simulation education program for all nursing students caring for frail older persons. Future research should focus on the development of a hybrid simulation education program that integrates virtual simulation and face-to-face simulation for frail older persons and the further evaluation of its effectiveness.

Purpose: The objective of this study is to determine the extent to which role conflict, the nursing work environment, and positive psychological capital of physician assistant nurses affect the work performance of physician assistant nurses. Methods: A structured questionnaire from 145 physician assistant nurses employed at one tertiary general hospital in D metropolitan city and one general hospital in S autonomous city was used for collection of data between July 22, 2024, and August 30, 2024. IBM SPSS/WIN program ver.29.0, employing descriptive statistics, t-tests, ANOVA, Pearson's correlation coefficient, and multiple regression analysis were used for collection and analysis of data. Results: Factors that significantly influenced nursing work performance included positive psychological capital (β=.57, p<.001) and assignment to a clinical department as a physician assistant nurse (β=-.17, p=.010), with an explanatory power of 47.6% (F=14.07, p<.001). Conclusion: Nursing work performance increased as positive psychological capital increased, and when the department of the physician assistant nurse was the clinical department, nursing work performance decreased compared to when the department was the nursing department. Therefore, in order to improve the work performance of physician assistant nurses, increased positive psychological capital is required and physician assistant nurses should belong to the nursing department.

Purpose: This study was conducted in order to examine the effects of death anxiety, family support, and knowledge of advance directives on the attitudes toward advance directives of aged patients with a coronary artery disease. Methods: The study subjects included 187 coronary artery diseased patients over the age of 65 who had received inpatient and outpatient treatment at a general hospital located in 'D' Metropolitan City. Data collection was conducted from July 8, 2022 to August 31, 2022. Results: The general characteristics of subjects who showed statistically significant differences in their attitude toward advance directives were as follows. The attitudes toward advance directives of subjects who were high school graduates and college graduates or higher, had a religion, and regarded their subjective health status as 'low', and had experienced thoughts about their own deaths were positive. In addition, the results showed a statistically negative correlation with death anxiety, while a positive correlation with family support and knowledge of advance directives. The results of regression analysis showed that the lower the death anxiety, the more religious, the higher the knowledge of advance directives, the higher family support, and the more 'low' the subjective health status, toward advance directives. The explanatory power was 31.3%. Conclusion: In order to improve the attitude of elderly coronary patients toward advance directives, reduction of death anxiety, strengthening of family support, and providing education regarding advance directives is required.

Purpose: This study was conducted to examine the influence of workplace bullying (WPB), bystander types, and psychological safety on the intention of advanced beginner nurses to report medication errors. Methods: A cross-sectional survey conducted from July to November 2024 used a structured questionnaire covering WPB bystander type, psychological safety, and intention to report medication errors. Data were collected from 188 advanced beginner nurses employed at two tertiary hospitals in South Korea. A multiple regression model, controlling for gender and the number of medication errors experienced, was used to assess the effects of WPB, the four bystander types (abdicators, facilitators, active defenders, supportive defenders), and psychological safety. Results: The model explained approximately 19.0% of the variance in the intention of advanced nurses to report medication errors. Supportive defender behavior and psychological safety had significant positive impacts, while workplace bullying had no significant effect. Conclusions: Strategies such as supportive defender behavior should be developed to promote positive bystander behaviors and enhance psychological safety for improved patient safety.

Purpose: This study was conducted to identify suicide risk factors among out-of-school adolescents and to explore variations in these factors according to suicide risk levels by employing multiple regression and quantile regression analyses. Methods: Data analysis was conducted on information obtained from 752 out-of-school adolescents to examine general characteristics, self-esteem, childhood abuse and neglect, social support, depression, and suicide risk. Results: Multiple regression analysis demonstrated that depression and self-esteem were significant predictors of suicide risk. Quantile regression revealed that all percentiles were consistently influenced by depression, while self-esteem showed a negative association at the 25th and 75th percentiles. Social support demonstrated a positive effect at the 25th and a negative effect at the 75th percentile. Although childhood abuse was significant only at the 75th percentile, childhood neglect was not found to be significant across any percentile. Conclusion: This study identified the differential effects of factors influencing the level of suicide risk among out-of-school adolescents. Suicide prevention strategies should be tailored to reflect the specific needs of each at-risk group.

Purpose: This study aimed to identify factors associated with pre-diabetes, focusing on types of obesity, and dyslipidemia indicators in community-dwelling Korean adults. Methods: Participants were adults (≥35 years) who understood the purpose of the study, had no cognitive impairment, and were able to communicate. Body mass index (BMI), abdominal obesity (AO) measurements, and blood tests, including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), were performed. Data were analyzed using t-test, chi-square test, Pearson's correlation coefficient, and multiple logistic regression analyses. Results: BMI, WC, TG, age, drinking status, age at drinking onset, and drinking frequency are predictors of pre-diabetes. The risk of pre-diabetes was 7.83 times higher in the obese group and 11.0 times higher in the highly obese group as compared to the normal control group. Participants with AO had a 9.42 times increased risk of pre-diabetes. For each 1-unit increase in TG levels, there was an associated 1.97 times increased risk of pre-diabetes. Those individuals aged 50-64 years and ≥65 years had a 5.97 times and a 7.87 times higher risk of pre-diabetes, respectively, as compared to those aged 35-49 years. Drinkers had a 5.37 times higher risk of pre-diabetes than non-drinkers. The risk of pre-diabetes was 35.02 times higher for those who started drinking under the age of 18, and 6.21 times higher for those who drank more than five times a month. Conclusion: This study will contribute to the early detection and prevention of type 2 diabetes by identifying risk factors for pre-diabetes in community-dwelling adults.

Purpose: This study aimed to investigate the mediating effect of meaning in work in the relationship between perceived organizational support, nursing work environment, and retention intention among hospital nurses. Methods: Participants included 105 nurses working in hospital setting. Using SPSS/Win 29.0, data analysis was conducted through descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression analysis. The significance of the indirect effects of the mediator was verified by the PROCESS Macro 3.4 (Model 4). Results: Perceived organizational support had a significant positive effect on meaning in work (𝛽=.36, 95% CI=0.16-0.57, p=.001). Consequently, meaning in work had a significant positive effect on retention intention (𝛽=.55, 95% CI=0.66-1.25, p<.001). Work environment also demonstrated a significant positive effect on meaning in work (𝛽=.58, 95% CI=0.39-0.67, p<.001), resulting in a significant influence on retention intention (𝛽=.57, 95% CI=0.66-1.32, p<.001). Furthermore, neither perceived organizational support(𝛽=.03, 95% CI=-0.12-0.18, p=.732) nor work environment(𝛽=-.02, 95% CI=-0.32-0.24, p=.812) showed a significant direct effect on retention intention when observed without the effect of meaning in work. Meaning in work was found to mediate the relationship between perceived organizational support, nursing work environment, and retention intention. Conclusion: These findings suggest that enhancing organizational support and improving the work environment can foster a greater sense of meaning in work which, in turn, increases the nurses' intention to remain in their current positions. Interventions aimed at strengthening the meaningfulness of nursing work may be effective in improving nurse retention rates.

Purpose: This study aimed to identify the impact of attitudes toward suicide attempt patients and suicide literacy on professional quality of life among clinical nurses. Methods: A cross-sectional descriptive study was conducted with 164 nurses working in emergency centers and trauma centers. Data were collected from June 17-23, 2024, using structured questionnaires. Statistical analyses included independent t-test, one-way ANOVA, Pearson correlation coefficient, and stepwise multiple regression analysis. Results: The mean scores were: attitudes toward suicide attempt patients 2.70±0.35 (5-point scale), suicide literacy 0.87±0.13 (1-point scale), compassion satisfaction 3.30±0.59, burnout 2.98±0.50, and secondary traumatic stress 2.44±0.36 (5-point scales). For compassion satisfaction, department satisfaction (β=.53, p<.001) and suicide literacy (β=.16, p=.012) were significant predictors (Adj R²=.328, F=40.75, p<.001). For burnout, female gender (β=.18, p=.017), department satisfaction (β=.22, p=.003), and attitudes toward suicide attempt patients (β=.25, p=.001) were significant predictors (Adj R²=.115, F=8.05, p<.001). For secondary traumatic stress, trauma center assignment (β=.18, p=.016) and attitudes toward suicide attempt patients (β=.28, p<.001) were significant predictors (Adj R²=.101, F=9.30, p<.001). Conclusion: Department satisfaction and suicide literacy positively influenced compassion satisfaction, while negative attitudes toward suicide attempt patients increased both burnout and secondary traumatic stress. These findings suggest the need for educational interventions to improve nurses' attitudes and understanding of suicide patients.
