Purpose. The objective of this study was to investigate factors influencing turnover intention index of work environment, emotional labor by hospital nurses Methods. A survey was conducted with 290 nurses who were working hospital. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients and multiple regression with SPSS window 18.0 program. Result. Findings revealed that; 1) The mean scores were 2.81 [range : 1-5] for work environment, 3.24 [range : 1-5] for emotional labor, 3.43 [range : 1-5] for turnover intention. 2) Pearson's correlation revealed work environment was negatively correlated with turnover intention but emotional labor positively correlated with the turnover intention. 3) Hrarchical multiple regression analysis showed work environment, ages, assign ward, period in current hospital, emotional labor significantly influenced turnover intention in hospital nurses. Conclusion. These findings can be utilized to development of strategies to improving the work environment, managing the emotional labor for decreasing turnover intention of hospital nurses so that can be long time.

The purpose of this paper is to provide a review of the background information regarding to the impact of personal control over the physical work environment on satisfaction with work environment and creativity at work. Today creativity has a significant and special place in business especially in innovative organizations which need creative people to generate new, and useful ideas for produce new products, services, work methods, systems etc. Moreover the design and appearance of workspace and individual ability to control the ambient conditions of the workplace have significant effect on their behavior, satisfaction and overall outcome including creativity. So the result of this study will contribute towards enhancing the understanding of the effect of office design to enhance employees' creativity.

The purpose of this paper is to propose a method of rest to reduce work load of night shift workers for night shift work. The experiment was carried out 10minutes preparing time, 45minutes first work, 10minutes first rest, 45minutes second work, 10minutes second rest between 2 and 4 o'clock that the lowest physiological function of workers. The methods of rest set up as four patterns (1) non-action rest (2) non-action rest + listening music (3) action rest + non-action rest, (4) action rest + non-action rest + listening music. For the measurements of experiment, heart rates(R-R interval), critical flicker fusion frequency(CFF), blood pressure, oral temperature, reaction time and error rates were considered as criteria for work performance. As a result, action rest + non-action rest and action rest + non-action rest + listening music were more effective to reduce work load additional work than non-action rest and non-action rest + listening music.

Study was made for the work study application in industry by sampling one thousand manufacturing companies. Small and medium industries are far behind in systematic application of the work study technique. Large industries are gradually introducing the work study technique systematically in line with the nation-wide quality control movement. Major sessions that the industries feel important in IE curriculum were QC, Work study and Cost accounting followed by the Organization theory, Industrial psychology, and Labor relations. Most of the industries were still less aware of the sophisticated fields such as OR, SE and Simulation. They put more emphasis on QC and TQC and as a result, work study should be closely bounded to TQC in order to systemize the work study application in the future.

Work related musculoskeletal disorders became a hot issue in Korea since many workers reported musculoskeletal disorder problems. Korean government enacted a law to require companies to take measures to prevent musculoskeletal disorders at work. This study found workers' WMSDs symptoms in squatting work posture which the rate of the occurrence was relatively high among work types to bring about WMSDs in railroad cars maintenance works and analyzed to compare the hazardous jobs in the industrial safety health law in South Korea with the caution jobs in Washington State in U.S. The hazardous jobs in South Korea were more effective in squatting work posture from this study result and this study data will be a great help to plan and carry out an effective prevention program about WMSDs.

In order to conduct construction projects effectively, the work delay factors would be managed by planned construction schedules. As construction works are delayed ceaselessly, the solution is to select and manage the key factors which delay the work ceaselessly. The subjects of this study were an apartment houses of reinforced concrete structure. Hidden work delay factor were extracted, the surveys were conducted and occurrence, severity and detection of each factor were analyzed. With this result, final orders of priority were fixed and key management factors were deducted and presented.

When PCB soldering is performed with microscope due to the electronic components' microminiaturization, workers' awkward upper body postures and difficulties being in focus among lens, object and eyes are one of reasons for productivity decline. The object of this study is to investigate the level of difficulties of work and the extent of productivity improvement by changing work interfaces from the work using microscope to the work using LCD monitor. Independent variables was usage of microscope and image system and dependent variables were upper body segments including neck, shoulder, back, and waist, task convenience and eye fatigue. The Visual Analogue Scale (10cm) was used for questionnaire and one way ANOVA (two levels) and two sample t-test were conducted. In addition, RULA rating was conducted for working postures. The result showed that interface changes of LCD monitor, suggested by productivity comparison per one Man Hour, highly contributed to work convenience and productivity improvement.

The work plate in a construction sites is a frequent cause of falling. But the bulk of the work plates lent to the construction site are handled carelessly by workers. There is general concern about performance declining by repetitive use. However, there is not a accurate guide, research and study on reuse work plate. This study was conducted in order to judge the classification guide to reuse work plate and measure the performance of classified reuse work plates. It is the result that even the A-grade plates classified to be in good shape by workers are below the performance standard. This means that the guide and classification are ineffective.

This study aims for determination of cutting work envelope of an articular robot for H-beam cutting. The robot has its own work envelope. The cutting of piece with groove requires the specific position of the torch which contracts the work envelope. This study suggested the new method to determine the cutting work envelope for this case. The method simplified the problem by use of the combination of inverse kinematics and forward kinematics. The method was used for cutting the H-beam with groove. The cutting work envelope was determined easily. The result was verified by 3D simulation system which implements the articular robot with 6 axes and the H-beam in the virtual shop.

Firefighters are exposed to extreme stress and risk owing to the nature of their work. This can lead to psychological burnout, and work overload can result in lethargy and depression. This study aims to analyze the mediating effect of depression on the impact of heavy workloads on psychological exhaustion among firefighters. We conducted a survey among firefighters in various regions of Korea to analyze the levels of work overload, depression, and psychological burnout. The analysis yielded the following results. First, work overload, depression, and psychological exhaustion showed positive correlations. Second, the mediating effect of depression on the relationship between work overload and psychological exhaustion was verified. This study confirms the necessity of the systematic management of psychological exhaustion by addressing the mediating role of depression in the context of heavy workloads. This study is expected to serve as foundational data for policy measures aimed at reducing the burden on firefighters, and maintaining their mental health.
