Purpose
This study aimed to identify the influence of positive psychological capital, role conflict, and authentic leadership on burnout among nurses working in comprehensive nursing care service wards of general hospitals. Methods: A descriptive cross-sectional survey was conducted with 208 nurses from four general hospitals. Data were collected using structured questionnaires between September 26, 2024, and October 18, 2024, and were analyzed using descriptive statistics, independent t-tests, one-way analysis of variance, Pearson’s correlation coefficient, and hierarchical multiple regression analysis. Results: Burnout showed a correlation with role conflict (r=.45, p<.001), positive psychological capital (r=-.62, p<.001) and authentic leadership (r=-.24, p<.001). In the regression analysis, the factors significantly associated with burnout included conflict with patients/guardians (β=.24, p<.001) and conflict regarding nursing practices (β=.22, p<.001), which are subdomains of role conflict. Among the components of positive psychological capital, optimism (β=-.37, p<.001) was identified as a significant protective factor against burnout. However, authentic leadership was not found to be a statistically significant predictor. Conclusion: To effectively manage nurse burnout, it is essential to develop strategic programs that focus on enhancing optimism. Furthermore, establishing clear delegation guidelines between nurses and nursing assistants is recommended.

Purpose
This study examined the effects of role conflict, work environment, and meaning of work on job embeddedness among physician assistants to provide foundational data for their retention and professional development. Methods: A descriptive survey was conducted with 180 physician assistants from six tertiary hospitals in Seoul and Chungcheong Province. Data were collected from July to November 2022. Role conflict, work environment, meaning of work, and job embeddedness were measured using validated scales. Data were analyzed using SAS Enterprise Guide 7.1 with descriptive statistics, the independent t-test, ANOVA, Pearson correlation coefficients, and multiple regression analysis. Results: Job embeddedness correlated positively with meaning of work (r=.28, p<.001) and work environment (r=.22, p=.002) and weakly with role conflict (r=.14, p=.045). Multiple regression identified meaning of work (B=0.32, p<.001), role conflict (B=0.13, p=.005), work environment (B=0.14, p=.018), and work type (B=-3.95, p=.004) as significant predictors (Adj. R²=19.8%). Meaning of work had the greatest impact. Conclusion: Enhancing job embeddedness among physician assistants requires improving the work environment, clarifying professional roles, and strengthening professional recognition and organizational support.
