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.

Purpose
This descriptive correlation study was designed to identify the job characteristics of advanced practice nurses (APNs) and the degree of nursing professionalism as factors influencing the political competency of APNs. Additionally, the relationship between these two factors and political competency was analyzed.
Methods
Data were collected through an online survey of 118 APNs from June 16 to September 16, 2021. The data collected were analyzed using descriptive statistics, a t-test, ANOVA, Scheffé ́’s test, Pearson’s correlation, and a multiple regression analysis using SPSS/WIN 25.0.
Results
Statistically significant differences were noted in the political competency of APNs based on age, workplace, position, experience as an APN, political education, and political party membership. Furthermore, political competency positively correlated with job characteristics and nursing professionalism. The factors affecting the political competency of APNs included skill variety, workplace, political education, political party membership, and nursing professionalism.
Conclusion
Findings of this study confirmed the importance of the political competency of APNs. Furthermore, policy efforts to promote independent job development reflecting the job characteristics of APNs and improvement in nursing professionalism are required, and support from professional nursing organizations is needed.
