Purpose: The purpose of this study was to identify the relationship of nurses' job performance with job embeddedness, self-leadership and social support and the role of self-leadership and social support in the relation between job embeddedness and job performance among general hospital nurses. Methods: The participants for this study were 244 nurses from 3 general hospitals in Seoul and Gyunggi Province. Data were analyzed using frequency, percentage, mean, standard deviation, t-test, ANOVA, $Scheff\acute{e}$ test, Pearson correlation and Hierarchical Multiple Regression. Results: Job performance showed positive correlations with job embeddedness (r=.56, p<.001), self-leadership(r=.68, p<.001), organizational support (r=.30, p<.001), supervisors' support (r=.31, p<.001) and colleagues' support (r=.31, p<.001). Job embeddedness and self-leadership had significant influence on nurses' job performance. However self-leadership and social support did not show moderating effects of job embeddedness on nurses' job performance. Conclusion: These findings indicate that job embeddednes and self-leadership are important factors to enhance nurses' job performance. Therefore, promoting activities for job embeddedness and self-leadership might be a way to increase nurses' job performance. As there was no moderating effects of self-leadership and social support on job embeddedness and job performance, further studies are necessary to refine these findings in different environments.

안드로이드 기반 스마트폰 플랫폼에서 사용하는 온디맨드 거버너 (Ondemand Governor)는 CPU 사용률(Utilization)에 따라 CPU 동작 주파수를 조절한다. CPU 사용률의 변화량은 작업 스케줄링에 의해 영향을 받으며, CPU 동작 주파수 증감에 따라 스마트 폰의 전력 소비량도 증감한다. 따라서 작업 스케줄링 방식에 따라 변하는 CPU 사용률 및 동작 주파수는 스마트폰의 전력 소비에 영향을 미친다. 이에 온디맨드 거버너 정책을 작업 스케줄링 기법에 적용시켜 CPU 사용률 및 전력 소비, 그리고 작업 마감시한 측면에서 비교 분석하였다.

Purpose: The purpose of this study was to analyze emotional labor factors influencing job satisfaction, intent to leave, and nursing performance of clinical nurses. Method: The participants were 384 clinical nurses working in a hospital. Study design was cross sectional survey. Subcategories of emotional labor (frequency of emotional labor, attentiveness of emotional display, mismatch of emotions) of emotional labor were dependent variables. Job satisfaction, intent to leave, and nursing performance were independent variables. Data were analyzed by hierarchial multiple regression. Results: The strength of emotional labor of nurses was similar for all participants in spite of differences in age, position, and clinical career. Total score for emotional labor was 3.21, frequency of emotional labor 3.34, attentiveness of emotional display 3.41, and mismatch of emotions 2.87. Mismatch of emotions influenced job satisfaction (F=12.53, p<.001) $R^2$ 27%, intent to leave (F=8.51, p<.001) $R^2$ 19%, and nursing performance (F=5.80, p<.001) $R^2$ 15%, Conclusion: These findings indicate that the factor (mismatch of emotion) is an important variable for clinical nurses in human resource management.

The data were collected by administering a questionnaire to fashion brand salespeople in Gwangju from September to October 2020. Using 235 responses, the data were analyzed with SPSS 27.0 for frequency analysis, reliability analysis, t-test, factor analysis, and regression analysis. The research results were as follows. First, the basic services of the salesperson comprised factors such as 'consideration and convenience', 'appearance and dress', and 'kindness and greeting', which are considered better variables to explain job performance than job satisfaction. Second, the salesperson's professional service consisted of 'fashion product knowledge', 'professional self-management', and 'store display technology' factors, which are good variables to predict job performance. Third, the relationship between the members of a salesperson's organization consists of factors such as 'headquarters relations', 'colleague relations', and 'emotional labor', which was better for explaining job satisfaction than job performance. Fourth, depending on the position, professional salespeople exhibited significantly higher values in job performance, basic and professional services of salespersons, and 'headquarters relations' factors, whereas there were no significant differences in job satisfaction, 'colleague relations' and 'emotional labor'. Lastly, the more sales career, the higher the job performance, and the basic services, professional services, and 'headquarters relations' factors of salespeople were also good.

Objectives: This study was conducted to investigate general characteristics, job characteristics, characteristics of hospitals, and hospital coordinators, and to investigate the factors affecting the job satisfaction of medical workers. Methods: The data was collected through a self-reported questionnaire among 435 workers in plastic surgery and dermatology clinics in metropolitan city G. We investigated general characteristics, job-related characteristics, characteristics of medical institutions and hospital coordinators, job performance of hospital coordinators, and job satisfaction of medical workers. T-tests, ANOVA, correlation, and multiple regression analyses were conducted to investigate the factors related with job satisfaction. Results: The job satisfaction of the medical workers and the perceived job performance of hospital coordinators were $3.55{\pm}0.40$ and $3.74{\pm}0.43$, respectively. In multiple regression analysis, drinking frequency, number of night shifts, number of work days, and hospital coordinator introduction years were associated with the job satisfaction of medical workers. The more the overall job performance of hospital coordinators increased, the higher was job satisfaction(B=0.458, p<0.001). In detail, the more job roles(B=0.218, p<0.001), core competency(B=0.145, p=0.005), and leadership(B=0.099, p=0.037) increased, the higher was the job satisfaction of medical workers. Conclusions: The job satisfaction of the medical institution workers was associated with the perceived job performance of the hospital coordinator. In order to increase the job satisfaction of medical institution workers, a hospital coordinator with specialized job performance will be able to improve job satisfaction by carrying out efficient work in the medical institution.
