Purpose: The purpose of this study was to identify correlations among emotional labor, servant leadership, and communication competence in hospital nurses. Methods: A self-administrated survey was conducted with a convenient sample of 210 nurses, using a structured questionnaire. The data were analyzed by descriptive statistics, t-test, ANOVA, and Pearson’s correlation coefficient using SPSS/WIN 20.0 program. Results: The mean emotional labor score was 3.4±0.60. There was very strong and negative correlation between emotional labor and servant leadership (r=-.896, p<.001). Communication competence was positively correlated with servant leadership (r=.298, p<.001) and moderately and negatively correlated with both frequency of emotional labor (r=-.166, p=.016) and the degree of attention to emotional expression (r=-.143, p=.039). Conclusion: As a strategy to reduce emotional labor of hospital nurses, the findings suggest training programs for nurses to enhance servant leadership and communication competence.

Purpose: The objective of the present study was to evaluate the effects of occupational exposure to low dose organic solvents on the prevalence of cardiovascular risk factors. Methods: Study design was retrospective cohort study subjected on 191 exposures and 118 controls working in a petrochemical manufacture company. The eight indicators related to CVD risk were followed up for five years from 2008 to 2012. The risk level was compared during the follow up years and subject’s characteristics, and the change of risk level were analyzed with repeated measures ANOVA and multiple logistic regression analysis. Results: At the start year 2008, the rate over cutoff value (ROCV) of BS (p<.001) and mean systolic BP (p=.017) were higher in organic solvent exposure group and the others showed no difference. And by the subject’s characteristics, odds ratio of the ROCV of BS were higher in organic solvent exposure group and work shift group as 2.51 and 3.07. Comparing the results in 2012 to those of 2008, cardiovascular disease risk in organic solvent exposure group was about 1.5 times higher than that of in the control group. Conclusion: Gradual increase in the CVD risk was identified in organic solvent exposure group. However, the risk might be influenced by shift work and bad behaviors rather than organic solvent exposure.

Purpose: The purpose of this study was to identify knowledge structure of the Korean Journal of Occupational Health Nursing from 1991 to 2014. Methods: 400 articles between 1991 and 2014 were collected. 1,369 keywords as noun phrases were extracted from articles and standardized for analysis. Co-occurrence matrix was generated via a cosine similarity measure, then the network was analyzed and visualized using PFNet. Also NodeXL was applied to visualize intellectual interchanges among keywords.

Newly emerging topics for 4-year period units were observed as research trends. Conclusion: Through this study, the knowledge structure of the Korean Journal of Occupational Health Nursing was identified. The network analysis of this study will be useful for identifying the knowledge structure as well as finding general view and current research trends. Furthermore, The results of this study could be utilized to seek the research direction in the Korean Journal of Occupational Health Nursing.

Purpose: This study was to identify the factors determining the turnover intention of nurses in Emergency Department (ED). Methods: The subjects were 123 ED nurses working at 10 general hospitals in Busan, Korea. The data were collected from August 15th to September 22nd, 2013. The collected data were analyzed using the SPSS program through descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression. Results: There were positive correlations between traumatic events experience and post-traumatic stress (r=.416, p<.001), between depression and traumatic events experience (r=.212, p=.001), between traumatic events experience and turnover intention (r=.289, p=.001), between post-traumatic stress and depression (r=.251, p=.005), and also between depression and turnover intention (r=.315, p<.001). Factors influencing turnover intention were depression and traumatic events experience with R2 value 16.7%. Conclusion: Considering these results, it seems that the important factors determining the turnover intention of nurses in ED are depression and traumatic events experienced by nurses. Therefore, an active plan is needed to develop strategies for reducing nurses' depression and traumatic events experienced by nurses.

Purpose: The purpose of this study was to investigate Korean blue-collar workers’ Health-related Quality of Life (HRQoL) and influencing factors in Korean blue-collar workers. Methods: Participants in this study were 109 Korean blue-collar workers. The survey included health-related, work-related, and psycho-social factors. SF-36 was used to measure HRQoL. The data were analyzed using Pearson's correlation, and hierarchical multiple regression analysis. Results: In the hierarchical linear regression model, when subjects’ psycho-social variables were included in the regression model, R2 change was statistically significant. The significant predictors for HRQoL were education level (β=.26, p=.023), depression (β=-.38, p<.001), and self-efficacy (β=.23, p<.001). Conclusion: The results of this study indicate that health care providers must have priority to consider psycho-social variables, especially depression and self-efficacy to improve HRQoL in Korean blue-collar workers.

Purpose: This study was to construct a structural equational model for explaining and predicting job stress of intensive care unit (ICU) nurses based on the Integrated model of stress of Ivancevich and Matteson (1980). Methods: The subjects of this study were 220 nurses at ICU. The data were collected from August 5 to 30, 2013 through self-reporting questionnaire survey. Results: According to the hypothetical model of this study, perceived nursing practice environment, perceived role conflict, perceived transformational leadership and perceived self-esteem showed statistically significant effects on job stress of ICU nurses directly. Professional self- concept indirectly affect job stress of ICU nurses. In conclusion, job stress of ICU nurses was directly influenced by nursing practice environment, role conflict, transformational leadership and self-esteem. Professional self-concept of the relationships among variables did not have a direct impact on job stress. Conclusion: Based on the results of this study, it is needed to develop stress management measures and programs considering these variables in order to adequately manage job stress of ICU nurses.

Purpose: The purpose of this study was to assess the psychosocial work environment of hospital nurses to identify influences of psychosocial work environment on stress, depression, sleep disorder, and burnout. Methods: A total of 219 nurses working in one hospital were surveyed by using the Korean version of the Copenhagen Psychosocial Questionnaire (COPSOQ-K) mental health and psychosocial work environment. The impact of the psychosocial work environment on mental health was analyzed using multiple regression. Results: Mental health variables are correlated with each other. The psychosocial work environment variables and mental health variables are mostly correlated. To assess the psychosocial work environment that affects mental health the most, multiple regression was used. Work-family conflict was the most powerful explanation of all the mental health variables. Work pace, social community at work, mutual trust among employees, predictability, and influence were found to be affecting some mental health variables. Conclusion: To improve the mental health of nurses, it is necessary to consider work pace, social community at work, mutual trust among employees, predictability, influence focus on work- family conflict.

Purpose: The purpose of this study was to investigate what factors are affecting job-seeking stress in nursing students. Methods: Subjects were 463 students from two 3-year and two 4-year colleges of nursing in K- Province in Korea. Data was collected from self-administered questionnaires. t-test, ANOVA, Pearson's and Spearman's correlation coefficients, and hierarchical multiple regression with dummy variables were used for statistical analysis of data. Results: Job-seeking stress was significantly different by school system (t=2.76, p=.006), family economic status (F=3.40, p=.005), characteristics (t=1.99, p=.047), academic achievement (F=6.54, p=.002), current weight control status (t=2.23, p=.026), times of cosmetic surgery (r=.11, p=.022), self-esteem (r=-.47, p<.001) and appearance stress (r=.40, p<.001). However, after controlling for general characteristics, self-esteem, and perceived appearance stress, job-seeking stress was significantly different by grade (1st vs 3rd, β=0.163, p<.001), academic achievement (low vs. high, β=-0.121, p=.0321), self-esteem (β=-0.224, p<.001), and appearance stress (β=0.099, p<.001). The explanation power of self-esteem on job-seeking stress was greater compared with that of appearance stress. Conclusion: Results of this study suggest that it is necessary for nursing students to develop intervention program aimed at reducing job-seeking stress, and it would be effective to focus on improving self-esteem for them.

Purpose: The purpose of this study was to investigate the relationships between psychosocial working conditions and psychological well-being depending on the gender among Korean interactive service workers. Methods: This study was a secondary analysis of the data extracted from the 2011 Korean Working Conditions Survey. For the present analysis, 15,669 workers who interact with others at work were selected. Based on the existing literature, a set of variables was chosen from the KWCS. Psychological well-being was measured using the WHO-5 well- being index. Results: The prevalence of poor psychological well-being was significantly higher among men (43.1%) than women (39.6%). Women were more likely to be exposed to demands for hiding emotions, bullying, and discrimination, whereas men were more likely to be exposed to psychological job demands, cognitive demands, demands for responsibility, role conflict and long working hours. Most factors were associated with poor well-being among women and men except demands for hiding emotions, skill discretion and development, physical violence, and sexual harassment. Conclusion: Based on these results, some practical suggestions are offered to help interactive service workers adjust to their duties.

Purpose: The purposes of this study were to investigate the degree of presenteeism, which lowers productivity when call center workers come to work with illness, and analyze the factors influencing it. Methods: A survey was conducted for three months from July to September, 2013 to collect data. Questionnaires were distributed to 1,500 workers at 30 call centers in Seoul and Gyeonggi Province, of which were 1,274 returned and analyzed for the study. Results: The findings show that the call center workers scored 15.4 points out of the maximum 30 on presenteeism based on SPS-6. The study examined factors that affect the presenteeism of call center workers and identified inner emotional labor, depression, subjective health condition, age and turnover intention as those factors. Their presenteeism was low when they engaged in more inner emotional labor, and when they had a good subjective health condition. The presenteeism was high when they had a higher degree of depression, were young, and had a higher turnover intention. Conclusion: The findings call for a need to implement a mental health promotion program to resolve call center workers' depression at work, help them manage their emotional labor to lower their turnover intention, improve their subjective health conditions, and run a health management program to consider the uniqueness of the young age group in order to prevent their increasing presenteeism.
