The purpose of this study was to investigate the influences of 5 intrinsic and 5 extrinsic factors on technology teachers' job satisfaction and commitment. The collected data from 108 technology teachers in Gwangju city and Jeolla Nam-do, were analyzed and tested at p<.05 or more by using Multiple Regression through SPSS program. The levels of the teachers' job satisfaction and commitment were respectively M=3.91 and M=3.69 at Likert scale. Among 5 intrinsic and 5 extrinsic factors, other factors except for two factors-work environment and salary were, even if a little, satisfied to the teachers. They were more satisfied with the intrinsic factors than the extrinsic. $R^2$=.515 was found between teachers' job satisfaction and the combination of 10 factors-achievement, work itself, responsibility, opportunity for growth, recognition, job safety, work environment, salary, supervision skill, human relation. $R^2$=.616 was between teachers' commitment with the combination of the factors. The combinations were respectively accountable for 51.5% of the job satisfaction change and for 61.6% of the commitment change. The relative importances of the factors were salary first, achievement second and others not for the job satisfaction, and achievement first, opportunity for growth second and others not for the commitment. The generalization of the above results is limited to improving technology teachers' job satisfaction and commitment at the secondary level in Gwangju city and Jeolla Nam-do.

The present study examined the causal relationships among nurses' job environment /job characteristics(work overload, lack of autonomy, professional role conflict, interpersonal relationships), maturity, job stress, job satisfaction and turnover intention by constructing and testing a theoretial framework. Based on Katz and Kahn's (1978) theory of organizational open system and Kahn, Wolfe, Quinn, and Snoek's (1964) theory of stress, nurses' turnover intention, job satisfaction and job stress were conceived of as outcomes of the interplay between personal characteristics and work environment. Personal aspects associated with outcome variables included professional knowlege and skill, and maturity(challenge, commitment, control, responsibility). The work environment factors involved work overload, lack of autonomy, professional role conflict, and interpersonal relationships (social support). Three university hospitals located in Seoul were selected to participate. The total sample of 443 registered nurses represents a response rate of 96 percent. Linear structural relationships (LISREL) technique was used to test the fit of the proposed conceptual model to the data and to examine the causal relationships among variables. The result showed that both the proposed model and the modified model fit the data excellently, revealing considerable explanatinal power for job stress and job satisfaction. The explanatory power of turnover intention was relatively lower than those of stress and satisfaction. In predicting nurses' stress, satisfaction and turnover intention, the findings of this study clearly demonstrated that professional role conflict might be the most important variable of the all the environmental variables and personal characteristics. The results were dis-cussed, including directions for the future research and practical implications drawn from the research were suggested.

Purpose: This study aimed to analyze factors that influence the job satisfaction of physical therapists working in hospitals. Methods: The study was done using a self-administered questionnaire associated with job satisfaction, which was completed by 352 physical therapists working in hospitals. Results: The average job satisfaction score was 3.16. Sub-items scores for job satisfaction were higher for overall satisfaction (3.21) and lower for job satisfaction of achievement (3.12) than the average score. Job satisfaction of subjects showed statistically significant differences with regard to differences in sex, marriage, type of hospital, year of total career, type of patients and motivation level (p<0.05). The average job stress score was 2.38. The sub-items of job stress consisted of problems pertaining to physical environment (2.28), job demand (2.54), job autonomy (2.31), social support (2.14), job instability (2.36), organized management system (2.44), inner motive (2.24), and job culture (2.26). Multiple regression analysis revealed that job satisfaction became significantly lower with increasing levels of job stress. Conclusion: These results suggest that the job stress of physical therapists is closely related to their job satisfaction. An effort to reduce job stress may be helpful in improving the health and quality of life of physical therapists who work in hospitals.

This paper discussed motivation, some theories of motivation and motivation of library personnel. The most important aspect of any organization is its workforce. Motivation arouses, energizes, influences and sustains behaviour and performance of employees. Motivating factors include extrinsic factors which pertain to the conditions under which a job is performed and intrinsic motivators which contribute to job satisfaction and subsequently increase productivity. Two levels of motivation were identified in the library: the need-factor motivation and the profession-related motivation. Need-factor motivation is well-pronounced in the lower cadre of library staff such as library assistants, clerical staff, and porters who set their priority on economic needs. The profession-related motivation occurs among professionally trained librarians whose motivation hinges self-fulfillment derived from professional growth and development. Other motivating factor in the library is job design which includes job rotation, job enlargement, and job enrichment. Job design specifies the contents or methods of any job in such a way that various requirements of a job can be effectively satisfied. Adequate motivation of library employees lies with the managers because they generally control work distribution, freedom and autonomy, work challenge Remove, staff development and training, and advancement opportunities. The managers are urged to create enabling environment to ensure improved commitment, satisfaction, and productivity of employees in the library.

The study aims were to verify the influences of job environment factors and work attitude on turnover intention of school foodservice employees, and then to verify the mediating effect of organization commitment between six areas of worklife and turnover intention so that organizations can intervene to reduce the turnover intentions of employees. The subjects were 205 employees who were working in the school foodservice field. The job environment factors were measured by six areas of worklife (workload, control, reward, fairness, community, value) and the organizational commitment was measured by two types of commitments (affective, continuance). The results were as follows. First, workload, reward, community and value of six areas of worklife reduced affective commitment, control and fairness increased continuance commitment, and affective commitment reduced turnover intention. Second, only reward and community showed direct effect on turnover intention, but all six areas of worklife had a statistically significant indirect effect on turnover intention through affective commitment. These results showed that job environment factors had both direct and indirect effect on employees' behavior through employees' affection. These findings imply that organizations can control employees' turnover intention by providing education or social support to maintain their affective commitment even when organizations cannot change job environment.
