Purpose: This descriptive study was to examine the effect factors on health promotion lifestyle of shift work nurses. Methods: The 418 working nurses who completed questionnaires with consent were analysed. Results: The average level of health promotion lifestyle of shift work nurses was 2.21 and it was significantly lower than 2.36 of fixed work nurses. In shift work nurses, the highest health promotion lifestyle was personal relationship of 2.79 and the lowest was physical activity of 1.58. The young, shorter shift work duration, unmarried and general nurses were evaluated as not-healthy diet. The old, longer shift work duration and married showed less physical activity. Less self-efficacy and more job stress, depression, fatigue showed lower health promotion lifestyle. Conclusion: Self-efficacy on health behavior of shift work nurses was the most effective factor on all areas of health promotion. Therefore, we need to develop a health promotion program including self-efficacy encouragement. We suggest that this program be more effective when more precisely characterized according to age, marital status, shift work duration, job position, and psychological problems such as depression and fatigue.

Psychological stress is a growing issue in work stress research because work stressors are closely related to depression； and depression, in turn, decreases organizational effectiveness. Considering such causal relationships of work stress, a comprehensive source to control work stress is needed for worksite mental well-being. This study was conducted to identify how social support at work controlled work stress and which characteristics of social support were effective on work stress reduction. The study participants were 240 workers employed in a public hospital in Georgia, U.S.A self-administered survey was given to employees with their pay slips, and followed by a hospital wide voice reminder for 7 days. Surveys were conducted over a 20-day period. The questionnaires asked about job demands, job control, social support at work, depression, job performance, absenteeism, and demographics. The social support construct was structured on the source of support at work and the kinds of support were provided. Statistical analyses were conducted in the structural equation modeling approach. Social support at work was directly related to high job control, low depression, and high job performance. High score of social support at work were significantly associated with high job control, low depressive symptoms, and high job performance. By source of support, only organizational support was positively related to high job control. Organizational support was more effective than supervisor and coworker support. Any stressors and their outcomes were not differenciated by the kinds of support. This result indicated that job control was influenced more by the source of support than the kinds of support provided at work； and the most efficient source of support was the organization. Organizational support was a strong factor in improving workers" perceived controllability of their jobs from a work stress reduction perspective.tive.

To understand the high expansion effects by adopting intake closing time in the cases of compensating intake air-mass and effective compression ratio simultaneously, fundamental study was carried out by using RICEM realizing Atkinson cycle. Intake air-mass and effective compression ratio were compensated by increasing supercharged pressure and geometric compression ratio. The results showed that the increasing rates of expansion ratio and expansion-compression ratio were increased by compensating both a intake air-mass and effective compression ratio the same tendencies were obtained with the increases of compression ratio and cut off ratio It was also found that LIVC has more advantages in expansion ratio and effective work than those of EIVC under above conditions.

The Performance of Pre-combustion Chamber Diesel Engine mainly depends upon the compression, combustion and Expansion Processes. The analysis of varying tendency of the work factors for crank angles during these processes, which are consisted of 5 items such as exothermic energy, flow work, work in nozzle part, kinetic energy and cooling energy, are considered important as basic elements for effective combustion and performance improvement. In this paper, varying tendencies of the theoretical factors are investigated with pressure data through experiments. By the results, the trends of work factors are presented as basic data for comparing the influencing effects on work.

Purpose: This study is to investigate the effect of nurse's competency empowerment and boss' job competency recognition on work performance. Methods: 216 nurses participated for data collection which was conducted from September 1, 2011 to September 10, 2011. The collected data were analyzed with SPSS/WIN 16.0 and with frequency test, ANOVA, Scheff$\acute{e}$ test and Multiple regression. Results: Firstly, the work performance in accordance with subject's general characteristics was found to be significant in the 50s, graduate school or higher education, Roman Catholic, charge nurse and 21-years or older. Secondly, the correlation among nurse's competency empowerment, boss' competency recognition and work performance was found to be positively related (r=.501~.639, p<.001). Thirdly, competency empowerment was found to be the most effective factor for work performance, followed by boss' competency recognition and career year, and these factors accounted for 63.5%. Conclusion: As the results show that the work performance is highly affected by the nurse's competency empowerment, boss' competency recognition level and career level in clinical environment, effective education programs are required to provide an appropriate experience to both entry-level and experienced nurses, as well as to enhance boss' competency empowerment at the same time.

The objective of this study is to analyze the research articles on clinical social work practice effectiveness to build a scientific and scholaristic image of clinical social work practice. The data for analysis were the articles published in 13 professional journals including Korean J. of Social Welfare in the period of 1979 to 1999. The appearance rate of effectiveness studies was 1.28% with only 18 articles. Experimental studies consisted only 4 out of 18, and there were only 10 Quasi-experimental studies. Statistical errors were observed in most studies, so it is too early to call that the clinical social work practice is either effective or not effective. In order to see the comprehensive trends of the clinical social work practice, other clinical papers were also examined. The appearance rate was also as low as 8.75% (effectiveness studies included). While 18 articles were about the therapy model, other clinical papers were about generic practice models. However, those newly developed generic practice models had not yet been widely used nor tested for effectiveness. Thus, the followings were suggested: active research activities with solid methodology, team work with the field, theory and method development, education and re-education, and collaborative team work with other related fields. It was also pointed that the cross analysis of research papers by the publishing period, authors major and other background variables would be useful.

There are insufficient models that find problems and solutions for accident prevention through risk assessment and suggest safe work process and work instruction from foundation works to finish work for accident decrease. This paper presents a quantitative risk assessment model by analysis of risk factors in each process such as foundation, erection, structure, equipment finish and etc based on accident examples and investigation on actual condition in building. In addition, the safety management system was developed to perform risk assessment of construction and use it for effective safety training for labor.
