The study originated in finding the way to improve the job satisfaction and job involvement of care worker, who work in the Elderly Care Facilities, by researching and analysing the influences on the job satisfaction and job involvement of their self-efficacy and empowerment directly or indirectly. The result from the influences on empowerment of care worker self-efficacy was that the higher the self-confidence and self-control efficacy were, the higher the empowerment was. And the influence on job involvement of self-efficacy was that the higher the self-control efficacy and job preference were, the higher the job involvement was. The influence on job satisfaction of care worker was that the higher the self-confidence, self-control efficacy, and job preference were, the higher the job involvement was. The higher care worker individual empowerment and environmental empowerment were, the higher their job involvement and job satisfaction were. We can find out that there is a mediated effect as an influence on job involvement and job satisfaction of self-efficacy.

The regulatory recognition, regulatory approval, and observance for employer, inspector, and worker groups were investigated for the Korean measurement system in working environments. The employer, worker, and inspector showed an agreement of 90~97 % for the measurement of working environments. This survey showed that the measurement system of working environments has been settled in Korea. However, this survey showed an agreement of 81~87 % for reporting the results of working environment, involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement. The employer recognized well for the measurement of working environments, involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement, but the employee did not recognize well them as much as the employer did. Thus, the improvements for the recognition for involvement of worker representative, improvement of working environment, and holding presentations for working environment measurement by the employee are needed.

Community involvement is to be the keystone of primary health care, Unfortunately, efforts to promote it failed in many countries. Author inquired into the reasons why such efforts fail, and the alternative strategies for effectively promoting it in Korean situation today. In doing so, the concept of community involvement is clarified as an amalgamation of two different concepts; one is that of the community development, and the other is that of approaches for overcoming the alienation of the people from the health care process. Stategies of community involvement in Korea so far followed the line of the community development, e.g. village health worker. It loses, however, the feasibility as Korea has experinced so cial and economic developpment. The strategies of the second line of thought is now more feasible; empowering the people by providing more information and enhancing comitment to health, improving acceptabilty of community involvemt on the part of the health professionals and the bureaucrats, and building the mechanism of community involvement into the health policy-making process.

The main purpose of this paper is to examine the relationship between employment relations characteristic and job involvement according to employment type in hotel corporations. Using data from 238 employees from hotel corporations, this research shows the results in the below. First, there is a significant difference in the employment relations characteristic(employment security and peer relationships) and job involvement. Second, the employment type does not moderates the relationships between employment relations characteristic and job involvement. Third, employment security and peer relationships are powerful factors to predict job involvement in both form of worker.

The Semiconductor industry in Korea has achieved a great contribution to the growth of its economy for the last 20 years with its product export ranked to #1 nowadays. However, the working environment in semiconductor industry is always exposed to a potential risk of critical safety issue for workers with many kinds of utilities used such as toxic chemicals, gases, high vacuum and high voltages of electricity. This study is focused on empirical research to find out the factors on safety climate and to examine the relationships of safety climate and safe work behaviour in the work site of Korea semiconductor industry. As a result of simulation, a strong positive relationships and safe work behaviour have been identified in this study. Its result and implications has been discussed and suggested further studies on its limitation from this study.

Previous work measurement methods need much time and effort of time study analysts because they have to measure required time through direct observations. In this study, we propose a method which efficiently measures standard times without involvement of human analysts using digital image processing techniques. This method consists of two main steps: motion representation step and cycle segmentation step. In motion representation step, we first detect the motion of any object distinct from its background by differencing two consecutive images separated by a constant time interval. The images thus obtained then pass through an edge detector filter. Finally, the mean values of coordinates of significant pixels of the edge image are obtained. Through these processes, the motions of the observed worker are represented by two time series data of worker location in horizontal and vertical axes. In the second step, called the cycle segmentation step, we extract the frames which have maximum or minimum coordinates in one cycle and store them in a stack, and calculate each cycle time using these frames. In this step we also consider methods on how to detect work delays due to unexpected events such as operator's escapement from the work area, or interruptions. To condude, the experimental results show that the proposed method is very cost-effective and useful for measuring time standards for various work environment.

Recent world-wide interest in activity-based travel behavior modeling has generated an entirely new perspective on how the profession views the travel demand process. This paper seeks to further promote the case of activity-based travel behavior models by providing some empirical evidence of relationship between travel time and activity duration decision for worker with transportation panel data. The travel time from home to work and from work to home, without activity involvement, is estimated by the Ordinary Least Squares (OLS) method. And, the travel time to and from the selected activity and the activity duration are modeled simultaneously by the Three Stage Least Squares (3SLS) method due to the endogenous relationship between travel time and activity duration. Two kinds of models, OLS and 3SLS, include selectivity bias corrections in a discrete/continuous framework, because of the inter-relationship between the choice of activity type/travel mode (discrete) and the travel time/activity duration (continuous). Estimation is undertaken using a sample of over 1300 household two-day trip diaries collected from the same travelers in the Seattle area in 1989. The behavioral consequences of these models provide interesting and provocative findings that should be of value to transportation policy formulation and analysis.

Purpose: To demonstrate arthroscopically the presence of bilateral shoulder "mirror lesions" due to overhead work. Materials and Methods: A cross-sectional study was performed in a historical cohort of 10 male tire plant workers who underwent MRI studies of both shoulders. Bilateral intraarticular shoulder pathology was diagnosed by magnetic resonance imaging and confirmed by arthroscopy. "Mirror lesions" were defined as similar pathology between an individual patient's two shoulders. Results: We report on ten patients who had bilateral "mirror lesions." The most common mirror lesions were tears of the rotator cuff. Most patients (7 of 10) had more than one mirror lesion in their shoulders. There were two bilateral full thickness tears involving the supraspinatus and infraspinatus, four bilateral partial thickness supraspinatus tears, six bilateral partial or upper corner lesion complete subscapularis tears, and one bilateral complete supraspinatus tear. Conclusion: Occupational overhead work with simultaneous use of both arms is associated with bilateral shoulder lesions verified by arthroscopy. By demonstrating the work-related bilateral shoulder involvement, this study suggests an etiopathogenesis for these lesions and provides rational for developing worksite prevention strategies.

This study is to investigate determinants of social workers' career commitment, compare the level of career commitment of social workeks by social work organization, and analyze the effects of career commitment on job attitudes. Social workers working for government agencies and community welfare centers and institutions in Busan city and Gyeongnam province were surveyed using structured questionnaires and 326 usable questionnaires were obtained. The questionnaires were analyzed for job, career, role, and organizational justice characteristics models and comprehensive model using SPSS/PC+.. The results are as follows; the level of social worker's career commitment was relatively high but the level of career commitment of social workers working for government agencies was slightly lower than that of social workers working for private agencies. According to the demographic characteristics, the level of career commitment of males was higher than that of famales. That of older workers was higher than that of younger worker, that of 2nd rank workers was higher than that of 1st rank workers. Task significance, task identity, feedback for the job done, career satisfaction, low role conflict, high distributive justice and interactive justice were related to higher level of career commitment while the skill variety was related to the lower level of career commitment. However, the main determinants differ according to the social work organization. Career commitment affected negatively on the career turnover intention while it affected positively on organizational commitment, organizational citizenship behavior, job involvement, and intrinsic job satisfaction. Therefore, different approaches and systematic measures are needed according to the organization.

Background: The surface mining industry has one of the highest fatality rates among private industries in the United States. Despite recent decreases in the fatality rates of comparable industries, the fatality rate in the surface mining industry has increased. Meanwhile, a lack of safety research in surface mining has hindered efforts to improve safety strategies in the surface mining workplace. Method: This study examined quarry workers' hazard identification skills by conducting a case study of a surface mining facility in the Mid-Atlantic region of the United States. Semistructured interviews were conducted with eight quarry workers who were employed at the mine facility. In addition to the interviews, data were collected through field notes, notes from an expert meeting with safety managers, and site photographs to explore quarry workers' safety behaviors in the workplace. Results: The results showed that quarry workers identified hazards and improved their safety performance by translating safety knowledge learned from training into practice, acquiring hands-on work experience, learning from coworkers, and sharing responsibilities among team members. Conclusion: This study contributes to understanding quarry workers' safe performance beyond what they have learned in safety training to include their interaction with other workers and hand-on experience in the workplace. This study informs practitioners in the surface mining industry to build a safe work environment as they design effective safety programs for employees.
