Purpose
This study explored the influence of verbal violence experience, surgical teamwork, and resilience on burnout among operating room nurses. Methods: Data were collected from 135 operating room nurses who had worked for more than 6 months in the tertiary and general hospitals in two metropolitan cities. The IBM SPSS Statistics 27.0 program was used for descriptive statistics, independent t-tests, one-way analysis of variance, Pearson correlation coefficients, and stepwise multiple regression. Results: Burnout showed a significant positive correlation with verbal violence experience (r=.38, p<.001) and significant negative correlations with surgical teamwork (r=-.41, p<.001) and resilience (r=-.60, p<.001). Verbal violence experience was negatively correlated with surgical teamwork (r=-.38, p<.001), whereas surgical teamwork was positively correlated with resilience (r=.51, p<.001). Multiple regression analysis revealed that resilience (β=-.46, p<.001), verbal violence experience (β=.26, p<.001), subjective health status (β=-.18, p=.010), and satisfaction with operating room work (β=-.16, p=.022) significantly influenced burnout and explained 50% of the variance. Conclusion: These findings indicate that resilience, verbal violence experience, subjective health status, and work satisfaction are significant factors associated with burnout among operating room nurses. Therefore, targeted interventions focused on strengthening resilience, preventing verbal violence, and enhancing work satisfaction are needed to reduce burnout.

Purpose
This study aimed to investigate the effects of job characteristics and professional self-concept on competency in forensic nursing among operating room nurses at university hospitals. Methods: Data were collected from 164 operating room nurses employed at university hospitals. The collected data were analyzed in SPSS 23.0, using the mean, standard deviation, independent t-test, one-way analysis of variance, Scheffé post-hoc test, Pearson correlation coefficients, and multiple regression analysis. Results: Professional self-concept showed a statistically significant positive correlation with forensic nursing competency (r=.60, p<.001). The following factors significantly influenced forensic nursing competency among operating room nurses: professional self-concept (β=.69, p<.001), total career lengths of <5 years (β=.21, p=.006) and 5-9 years (β=.20, p=.011), and job characteristics (β=.19, p=.007). A three-step regression model was statistically significant (F=29.74, p<.001) and the total explanatory power of the regression model was 41.4%. Conclusion: This study identified that professional self-concept, total career years, and job characteristics as the most significant factors influencing operating room nurses' forensic nursing competency. Therefore, it will be necessary to develop educational programs to improve professional self-concept and job characteristics.
