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 investigate the relationships among nursing skill mix, missed nursing care, and adverse events according to the nursing skill mix and the factors influencing.
Methods
This study is a descriptive survey that used survey data were collected from 158 nurses working in comprehensive nursing care wards in small and medium-sized hospitals. The data were analyzed using the t-test, analysis of variance, and multiple regression analysis.
Results
The average age of the study participants was 37.9 years, and they had over 10 years of experience. The average mean ratio of nursing skill mix 1 was 69.98. For nursing skill mix 2, the average mean ratio was 68.44%. The mean score for missed nursing care was 1.33, and the mean score for adverse events was 1.90 points. The factors affecting adverse events experience were missed nursing care, total work experience of >3 years, number of beds between ≥200 and <300.
Conclusion
Our findings suggest that patient safety and management education should consider the nurses’ age and total work experience. Furthermore, nursing workforce management, particularly focusing on nursing assistants in small- and medium-sized hospitals, is essential for fostering a safer healthcare environment.
