Purpose
This study aimed to determine the effects of self-leadership on job performance competency and organizational commitment among insurance review nurses. Methods: A nationwide online survey was conducted using structured questionnaires. Participants included 189 insurance review nurses working in advanced general hospitals and general hospitals in South Korea. Data were collected through self-administered questionnaires between August 19 and September 17, 2021. Data analysis was performed using descriptive statistics, independent t-tests, one-way analysis of variance, Pearson’s correlation coefficients, and hierarchical multiple regression with IBM SPSS version 23.0. Results: The mean score for self-leadership was 3.64±0.43 out of 5, for job performance competency was 3.10±0.68 out of 5, and for organizational commitment was 4.38±1.09 out of 7. Statistically significant positive correlations were observed among self-leadership, job performance competency, and organizational commitment in insurance review nurses. Hierarchical multiple regression analysis showed that self-leadership explained an additional 13.9 percentage points of variance in job performance competency and an additional 5.3 percentage points in organizational commitment. Self-leadership emerged as a statistically significant predictor of both job performance competency and organizational commitment. Conclusion: This study empirically demonstrates that self-leadership has significant effects on job performance competency and organizational commitment among insurance review nurses. These findings provide empirical evidence relevant to human resource management strategies for insurance review nurses.

Purpose
This study investigates the mediating effect of job embeddedness in the relationship between nursing professionalism and turnover intention among clinical nurses. Methods: A nationwide online survey was conducted using a structured questionnaire. Participants included 204 clinical nurses from tertiary hospitals in South Korea. Data on general characteristics, nursing professionalism, job embeddedness, and turnover intention were collected through self-reported questionnaires from March 19 to March 22, 2024. The analysis involved descriptive statistics, independent t-tests, one-way analysis of variance, Scheffé test, Pearson's correlation coefficients, multiple linear regression analysis, and bootstrapping, using SPSS/WIN version 29.0 and the SPSS PROCESS macro 4.2 version programs. Results: The mean score of nursing professionalism was 3.48±0.45 out of 5, job embeddedness was 3.13±0.52 out of 5, and turnover intention was 2.80±1.00 out of 5. Nursing professionalism did not directly impact turnover intention (B=-0.07, p=.649). Job embeddedness acted as a mediating factor in the relationship between nursing professionalism and turnover intention (B=-0.46, p<.05). Conclusion: These findings suggest that increasing job embeddedness can reduce nurses' turnover intention. Therefore, to decrease nurses' turnover intention, it is essential to enhance nursing professionalism while simultaneously promoting job embeddedness.

Purpose
This study aimed to conduct a systematic review to explore leadership-related variables among nurses in the novice and advanced beginner stages, identify research trends, and analyze effect sizes to provide evidence for developing a nursing leadership program. Methods: A systematic review and meta-analysis were conducted according to PRISMA(Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and NECA (National Evidence based Healthcare Collaborating Agency) guidelines. Literature was searched from February 26 to April 26, 2024 using databases including KISS, KMbase, RISS, KoreaMed, Science ON, CINAHL, CENTRAL, Embase, PubMed, Web of Science, and Korean nursing journals. Meta-analysis was performed using R version 3.6.2. Results: From 589 articles, five studies were selected. Self-leadership was most frequently studied topic (80.0%). Leadership antecedents with k≥2 included preceptor’s clinical teaching behavior (correlation effect size [ESr], 0.34). For leadership outcomes, effect size analyses for cases with k≥2 indicated resilience (ESr, 0.72), nursing performance (ESr, 0.69), and organizational socialization (ESr, 0.31), with resilience demonstrating the largest effect. Conclusion: Preceptor’s clinical teaching behavior, resilience, nursing performance, and organizational socialization were identified as critical factors in leadership of the nurses at novice and advanced beginner stage. Enhancing leadership requires preceptor support, which can improve resilience and help early-career nurses overcome challenges. Therefore, strategies for leadership development must include specific measures to ensure preceptor support.

Purpose
This study aimed to explore customer perspectives of nursing services in tertiary hospitals.
Methods
The data comprised mobile Voice Of Customer (VOC) data related to “nursing” or “nurses” generated from June 25, 2019, to December 31, 2022, in a tertiary hospital. A total of 44,727 VOC data points were collected, of which 4,040 were selected for the final analysis. Text network analysis and topic modeling were conducted using NetMiner 4.5.1.
Results
Topic modeling identified five topics for positive aspects and four topics for areas requiring improvement. The positive aspects were: 1) sincere nursing care; 2) rapid response from professional medical staff; 3) teamwork for delivering customer-centric services; 4) provision and coordination of system-based healthcare services; and 5) customer-focused responsiveness. The areas requiring improvement were: 1) demand for skilled nursing care tailored to customer expectations; 2) demand for enhanced communication and reduced mechanical responses; 3) demand for appropriate handling of diverse situations; and 4) demand for overall improvements to the healthcare system, including reservation systems.
Conclusion
These results may be used to enhance customer and patient experiences in tertiary hospitals and are necessary for utilization from a hospital management perspective.
