The aim of this study was to investigate the relationship between job stress and smoking behaviors among small scale manufacturing male workers. A self administered questionnaire was given to 856 male workers employed in 24 work places under 50 members of manufacturing industries. As a results, the smoking rates of small scale manufacturing male workers was 35.2%. In the results of multiple logistic regression analysis to know the relationship between job stress and smoking behaviors, the Odds ratio of the total score of Korean Occupational Stress Scale(KOSS) and its subarea(physical environment, job demand, organizational system, lack of reward and occupational climate) were significantly increased in high risk group than normal group. These results suggested that job stress may play a significant role in the smoking behaviors in the high risk group than normal group of small scale manufacturing male workers.

Objectives: This study was conducted to investigate the association between job stress and mental health among male and female workers in a large electric manufacture company. Methods: A cross-sectional study was carried out on 3,228 employees who participated in annual medical check-up working in a large electric manufacture company in Gyeonggi Province. Medical check-up and self-administrated questionnaire were performed at the same time. Korean Occupational Stress Scale Short Form (KOSS-SF) and Psychosocial Wellbeing Index Short Form (PWI-SF) were applied to assess occupational stress and mental health. Hierarchical multiple linear regression and multiple logistic regression were performed to estimate the association between job stress and mental health. Results: The proportion of high risk of mental health was 17.1% in male, and 46.9% in women. Job stress had a greater effect on mental health than other general and work characteristics. All subscales of job stress were revealed to affect mental health. Bad occupational climate and lack of reward are the strongest risk factors in mental health of male and female respectively. Conclusions: Our results suggest that job stress could affect mental health among large electronic manufacture workers.

Purpose: The purpose of this study aimed to investigate job stress levels of occupational health managers and whether job stress levels were affected by various factors such as size and types of company and work-related characteristics of occupational health managers. Methods: The study was conducted from May to September 2011 in the chemicals manufacturing factories in Korea and total subjects were 59 occupational health managers. We measured job stress levels of occupational health managers using Korean occupational stress scale (KOSS) questionnaires and the information of company characteristics was obtained using a self-reported questionnaire. Results: The characteristics of company such as type, size and industries and job characteristics of occupational health managers were significant factors in job stress. Job demand, job control, job insecurity, organizational system and occupational environment scores were significantly associated with type, size and industries of company. In multiple regression analyses, we found that job demand was significantly associated with occupational position and type of company, and job insecurity was significantly associated with working hour. Also, we found that lack of reward was significantly associated with education level, speciality, duration of work and hour and type of company. Conclusion: These results indicate that job stress of occupational health managers is significantly associated with work-related characteristics and company's characteristics.

The ultra hard X-ray band (14-195 keV) provides an important and unbiased way to understand black hole growth and relationship to the host galaxy. The Burst Alert Telescope (BAT) instrument on the Swift satellite has surveyed sky to unprecedented sensitivity, improving the number of known hard X-ray sources by more than a factor of 20 to 836 nearby AGN. The BAT AGN Spectroscopic Survey (BASS) is a study for the first large (N>600) and complete sample of ultra hard X-ray selected AGN with optical spectroscopy. In this talk, I present the observed relationship between black hole mass, bolometric luminosity, and Eddington ratio with optical emission line ratios. We show that [NII]/Ha ratio exhibits a significant correlation with Eddington ratio. We propose that the [NII]/Ha ratio is a useful indicator of Eddington ratio with 0.6 dex of scatter, and that it can be used to measure Eddington ratio and thus black hole mass from the measured bolometric luminosity, even for high redshift obscured AGN.

Purpose: The purposes of this study were to identify musculoskeletal symptoms and to investigate factors associated with musculoskeletal symptoms in small and medium sized hospital nurses. Methods: The data were collected from 206 nurses working in Jeonnam. We used self administration questionnaires of KOSHA GUIDE H-9-2012 for musculoskeletal symptoms, PWI-SF for psychosocial stress, KOSS for job stress, and HPLP-II for health behaviors. The collected data were analyzed using the $x^2$, t-test, and logistic regression analysis in SPSS Ver. 23.0. Results: Sixty-six percent of the subjects had musculoskeletal symptoms. The shoulder had the highest symptom at 38.3%, followed by lower back at 32.5%, and neck at 29.1%. The mean and standard deviation score of psychosocial stress were $24.06{\pm}6.01$, those of job stress were $2.38{\pm}0.23$, and those of health behaviors were $2.14{\pm}0.39$. The items that were significantly different according to musculoskeletal symptoms were career ($x^2=6.67$, p<.036), one week overtime ($x^2=7.27$, p<.026), subjective health status ($x^2=4.29$, p<.038), and psychosocial stress ($x^2=7.99$, p<.010). In logistic regression analysis, career, and psychosocial stress were found to affect musculoskeltal symptoms. Conclusion: It is necessary to conduct preventive intervention to reduce musculoskeletal symptoms according to career and psychosocial stress for small and medium sized hospital nurses.

To improve work environment for health managers, it was investigated about effect of job stress, psychosocial stress and job satisfaction of health managers on job commitment. The sample used in this study consisted of 166 persons of industrial health managers. The data were collected with self-administered questionnaires between November 2007 and January 2008, and the results analyzed with ANOVA and multiple regression analysis. Job stress was evaluated by using a Korean Occupational Stress Scale(KOSS), and Psychosocial wellbeing index-Short Form(PWI-SF) was used for a psychosocial stress level evaluation. Organized commitment evaluated loyalty, compensation, welfare, job immersion, external employment opportunity, total agreement with employer and personal ability development. In path analyses, interpersonal conflict, lack of reward, psychosocial distress were associated with job satisfaction. And psychosocial distress, job demand, job insecurity, organizational system, occupational climate were associated with organizational commitment. In considering above findings, the health program for psychosocial distress, improvement of job demand, job insecurity, organizational system, occupational climate would be implemented to increase organizational commitment of Health manager.

Objectives: The purpose of this study was to identify the effects of sleep quality and occupational stress on health-related quality of life among a university's security workers. Methods: 128 security workers voluntarily participated in the study. The survey asked demographic, health related, job related factors, the Korean Occupational Stress Scale Short Form(KOSS-SF), sleep quality questionnaire, and 12-Short Form Health Survey version 2.0(SF-12v2). The data were analyzed by using descriptive analysis, t-test, ANOVA, multiple linear regression, and multiple logistic regression. Results: The interrupted rest time was significantly negatively related to occupational stress. The occupational stress significantly affected sleep quality. The significant variable affecting Physical Component Score(PCS) and Mental Component Score(MCS) was sleep quality and occupational stress, respectively. Conclusions: HRQOL was founded to be affected by occupational stress and sleep disorder among the security workers. Based on this study, we suggest that the management of both occupational stress and sleep quality is crucial to improve the HRQOL.

Objective : The purpose of our study was to investigate the relationship between job stress and depressive disorder among emotional laborers in a city. Methods : A total of 677 emotional laborers living in Jeonju-city participated in this study. The participants completed survey questions regarding demographic characteristics, job stress (using the Korean Occupational Stress Scale-24, KOSS-24), and depression (the Patient Health Questionnaire-9, PHQ-9). Logistic regression was performed to estimate the association between job stress and depression. Results : Our results indicated that 34.9% of the participants had a high risk of total job stress and 21.7% of participants had depression. In the multivariate logistic regression analysis, female sex (OR=1.66, 95% CI=1.01-2.72) and total job stress (OR=3.84, 95% CI=2.57-5.75) were significantly associated with depression after adjusting for confounding factors. Among the subscales of job stress, job demand (OR=3.06, 95% CI=1.99-4.72) and occupational climate (OR=1.88, 95% CI=1.19-2.97) were significantly associated with depression. But insufficient job control, interpersonal conflict, job insecurity, the organizational system and lack of rewards were not. Conclusion : Among the emotional laborers, job stress, particularly job demand and occupational climate, were major contributing factors associated with depression. Early screening and preventive strategies focusing on job stress could reduce the impact of depression in emotional laborers.

This study was conducted to compare differences in dietary habits and snack consumption behaviors according to level of job stress among 20- to 30-year-old office workers. Subjects were 205 office workers working in companies located in Seoul and the metropolitan area. Self-administered questionnaires written by the subjects were statistically analyzed by the SPSS 20.0 program. Subjects were classified into a high-risk job stress group (n=102, High-RSG) or low-risk job stress group (n=103, Low-RSG) by level of job stress. For dietary habits, the duration of meal time before suffering from job stress in High-RSG was significantly faster compared to Low-RSG. Appetite after suffering from job stress in High-RSG was significantly higher compared to Low-RSG. For snack consumption behaviors, the reason for snack intake was 'job stress' for 42.2% in High-RSG and 'hunger' for 31.1% in Low-RSG (p<0.05). Energy intake in the form of chocolates, castellacakesmuffins, and flavored milk during working hours was significantly higher in High-RSG compared to Low-RSG (p<0.05). Therefore, this study suggests that dietary guidelines to ameliorate job stress should be developed in order to manage and improve dietary habits caused by suffering from job stress among young office workers at companies.
