Purpose: The purpose of this study was to identify the effects of violence experience, emotional labor and job stress on clinical nurses' depression and to provide suggestions for improving the quality of patient care. Methods: This research involved 257 clinical nurses who were working at an acute care hospital with at least 200 beds in S city and K province. Data were collected from May 23 to June 7 in 2014 and were analyzed using IBM SPSS version 21.0. Results: The results show that 98.1% of subjects had violence experience in the past year and the violence experience included 44.4% physical threat, 37.5% verbal violence and 18.1% physical violence. The average scores were emotional labor 3.57, job stress 3.54 and depression 21.16. There were positive correlations among violence experience, emotional labor, job stress and depression (p<.01). There were also significant co-relationships between depression and violence experience (r=.21, p=.001), between depression and emotional labor (r=.48, p<.001) and between depression and job stress (r=.31, p<.001). Conclusion: The results suggest that it is necessary to set up guidelines for clinical nurses to manage violence, emotional labor and job stress in order to create better working environment and to improve quality of patient care.

Purpose: This study was to explore factors affecting musculoskeletal symptoms of the child care centers' teachers in Korea. Methods: This study was a descriptive research, using a cross-sectional survey. Convenience samples of 230 child care centers' teachers aged 20 to 65 were selected. A self-administered questionnaire was used to measure general characteristics, job-related characteristics, exercise habit, fatigue and musculoskeletal symptoms of the body parts. The data were analyzed with the SPSS/WIN 21.0 program. Results: Shoulder pain (73.5%), low back pain (72.6%) and wrist/hand pain (57.8%) were the most common musculoskeletal symptoms. Shoulder pain significantly differed depending on the age of children in charge at the child care center (p<.047). The exercise habit was related to low back pain (p<.028) and the career was linked to wrist/hand pain (p<.046). The logistic regression analysis revealed exercise habit and fatigue were the risk factors on musculoskeletal symptoms of many body parts. Conclusion: These results suggest that interventions targeting the child care centers' teachers should be considered job-related characteristics and fatigue in order to prevent musculoskeletal disorder. Thus, there continues to be a need to develop exercise program for the child care centers' teachers.

Purpose: This study was performed to investigate the present condition of drug abuse and its association with depression, self-rated health and health behaviors by job status in Korean adults. Methods: Data were derived from the study on four addiction problem and suicide in 2014. Multiple logistic regression was used to analyze patterns of drug abuse according to depression, self-rated health and health behaviors. Results: The prevalence of drug abuse during the past year was 17.1% of the 4,018 subjects. About 3.3 times risk for drug abuse was found among individuals who had high depression scores. The risk of drug abuse was higher among those who were smoking (OR:1.46, 95% CI:1.17~1.83), drinking more frequently (OR:1.30, 95% CI:1.07~1.58), sleeping insufficiently (OR:1.31, 95% CI:1.03~1.67), eating irregularly (OR:1.45, 95% CI:1.19~1.76). Drug abuse problem was detected more seriously among employed than unemployed adults. Conclusion: Health-related behaviors, such as smoking, drinking, sleeping, eating should be considered simultaneously when designing strategies to deal with drug abuse problem, and it is important to understand the interaction between drug abuse and mental health.
