Objectives: The purpose of this study is to analyze factors associated with depression among workers in South Korea by socio-economic factors, health behaviors, and working conditions. Methods: Study subjects include 4,251 adults (19 and older) who are currently working using the data from 2009 National Health and Nutrition Survey. Data were analyzed using frequency test, $X^2$ test, and multiple logistic regression. Results: Multiple logistic regression analysis showed that gender (OR=1.91, p<.001), age (OR=1.53, p=.030), marital status (31-39: OR=1.88, p=.029) were significantly related to depressing among socio-economic factors. Next, among health behaviors factors, perceived health status (Poor: OR=1.76, p=.049; Very poor: OR=3.46, p=.002) was statistically significant. Among characteristics of work environment, trust and respect (OR=1.34, p=.049) and working with hidden emotion (OR=1.88, p<.001) were significantly related to depression. Conclusions: In order to manage and reduce depression among workers, it is important to develop appropriate mental health promotion programs both in work places and in regulations.

Purpose: This study aimed to explore professional autonomy, nursing work environment, and clinical decision making ability and to determine predictors of clinical decision making ability among clinical nurses. Methods: A cross-sectional design was used in this study and 263 clinical nurses were selected from advanced-level hospitals with over 500 beds located in D metropolitan city. Independent t-test, ANOVA, Pearson's correlation coefficients and hierarchical multiple regression analyses were done with the SPSS/WIN 20.0 program. Results: Clinical nurses reported moderate levels of professional autonomy, nursing work environment and clinical decision making ability. Marital status, professional autonomy and nursing work environment accounted for 25% of variance in clinical decision making ability required in various clinical settings. Importantly, being married, higher level of professional autonomy, and greater satisfaction with work environment were significantly associated with better decision making ability. Conclusion: Findings indicate that improving the quality of decision making in the healthcare settings requires awareness of the multiple effects of individual, occupational and environmental features. Nurses' ability to make effective clinical decisions may rely on personal characteristics, the degree of autonomy in their job, and nurses' satisfaction with their work environment.

Purpose: The study examined core job characteristics and job preference to explain work performance among critical care nurses. The theoretical model was constructed based on the job characteristics model with core job characteristics as exogenous variables, and work performance and job preference as endogenous variables. Methods: A total of 228 hospital nurses participated in the study from May to September, 2015. Data were collected through structured questionnaires and analyzed using structural equation modeling. Results: The model showed a good fit to the data with $x^2/df=2.90$, goodness of fit index = .91, root mean square residual = .20, comparative fit index = .93, and incremental fit index = .93. The core job characteristics explained 64% of the variance in job preference. The core job characteristics and job preference explained 52% of the variance in work performance. Conclusions: The core job characteristics can explain the work performance among critical care nurses through job preference. Effective strategies to improve the work performance among critical care nurses should focus on the application of the core job characteristic into a productive work environment. Further studies are warranted to explore the role of job preference of critical care nurses in promoting their work performance.

The purpose of this study is to review the labor force partitpation rate and work environment characteristics of female workers to provide basic information for establishment and implementation of effective policies related to accident prevention and workers health protection for female workers. It was analyzed employment status, work environment and injuries and illnesses based on economic activity census results, compensation of industrial injury and the second working condition survey. According to economic activity census results, female labor force participation rate has been steadily increased, whereas male labor force participation rate has been decreased since 1970. Industrial accident rate has been declined in male workers but that in female workers has been steadily increased even though male workers were higher accident rate than female workers. It was evaluated that female workers are vulnerable to industrial injuries and illnesses in the aspect of their working environment and employment status. Also, Substantial differences between female and male workers in occupational exposure patterns, occupational disease and occupational environments were observed. Therefore it was recommended that special care programs for female workers such as a specialized monitoring and management program should be introduced in the near future.

Purpose: This study aims to assess the effects of psychosocial work environment and self-efficacy on stress, depression, and burn-out among office workers. Methods: Survey data were collected from 331 office workers who worked in one workplace from April 10 to 30, 2012. The impact of psychosocial work environment and self-efficacy on stress, depression, and burn-out was analyzed with hierarchical multiple regression using SAS version 9.3. Results: Work-family conflicts and emotional demands were identified as main factors influencing mental health. Other work environment factors influencing mental health were role clarity for stress, possibilities for development, meaning-of work, social support-from supervisors and job insecurity for depression, and social community at work for burn-out. Self-efficacy was correlated with most psychosocial work environment and factor with independent influence on stress and depression. The final models including general characteristics, psychosocial work environment, and self-efficacy accounted for 34%, 44%, and 36% for stress, depression, and burn-out respectively. Conclusion: To promote mental health in office workers, there is a need to decrease work-family conflicts and emotional demands and to improve work organization and job contents, social support, and self-efficacy.

As the environmental regulations become stricter, new machining technologies are being developed which takes envi ronmenta 1 aspects into account . Since cut t ing oi I has some impact on environment. many researches are being carried out to minimize the use of cutting oi I. The methods for minimizing cutting oil usage includes the following techniques: I ) Cooling of tools and work piece. 2) Useage of compressed cooling air for the removal of chip. 3) Minimal useage of environment-friendly vegetable cutt:ngoiI for lubrication between chip and tools. Since the turning machine is continuous, tools are under constant thermal load and tool wear increases as the lubricative performance degrades. Also surface roughnesses have a direct influence on turning. In order to examine the characteristics of turningmachining, this work investigates experimentally the degree of tool wear and characteristics of surface roughness in relation to machining conditions, supply methods, and cooling methods.
