Today's health care environment is rapidly changing and nurse administrators' leadership styles need to identify in nursing organization to achieve organizational objectives. By Bass(1985), transformational leadership stimulates the subordinates to be creative and achieve organizational objectives and is related to job satisfaction, job involvement, productivity, and organizational commitment. Transformational leadership process consists of charisma, intellectual stimulation, individual consideration. The purpose of this study was to identify the effect of transformational leadership and personal characteries on nurses' job involvement. The subjects for this study consisted of 594 nurses from 8 University Hospitals and General Hospitals. The data were collected by personal characteristics scale, transformational leadership scale, and job involvement scale. The factor analysis, Cronbach's alpha analysis, Pearson correlation analysis, multiple regression analysis and hierarchical multiple regression analysis were used for the statistical method. The results of this study were found that (1) charisma dimension of transformational leadership has positive influence on nurses' job involvement ; but another two dimensions (intellectual stimulation and individualized consideration) did not showed significant effect on job involvement (2) nurses' personal characteristic (internal locus of control) moderated the effect of transformational leadership on job involvement.

This study was carried out to assess the relationship between jobstrain, psychosocial distress and homocysteine. The study design was cross-sectional, and included 152 industrial workers in middle sized city. A self-adminstered questionnaire measured general characteristic, job strain and psychosocial distress. Blood was drawn into EDTA tube, and total plasma homocysteine was measured by HPLC. Homocysteine in the high job demand group was sagnificantly higher than that in the low job demand. Cholesterol in the high job control group was significantly higher than that in the low job control. Homocysteine was significantly higher in the high job strain group than that in the other group. Folate and vitamin B12 showed a significantly negative correlation with homocysteine. Multiple regression analysis was used to determine whether the psychosocial distress and other variable contributed to explaining the homocysteine. Stress correlates with the homocysteine.

Objectives : The purpose of this study was to grasp association with dental hygienists' job expectation through correlation between curricular subjects for the department of dental hygiene and job. Methods : It carried out convenience sampling of dental hospitals where are located in Capital Area, and then conducted a self-administered questionnaire survey targeting 274 dental hygienists who are working here. The statistical program was analyzed by using PSAW 18.0. Results : Research subjects' 60.2% experienced turnover. Its reason accounted for 31.7% with the working condition. As a result of examining difference in experience of turnover according to dental hygienists' individual characteristic and working form, the significant difference was shown in age, marriage, annual salary, working institution, and career. In consequence of confirming association between curricular subjects and job, the majority showed high correlation. However, the correlation with oral physiology, clinical dental hygiene, and dental clinics showed low correlation as the insignificant variable. Conclusions : As a result of this study, the high correlation between curricular subjects and job can be considered to reflect dental hygienists' job expectation. On the other hand, the working condition, professional sense, and turnover experience, which are factors related to dental hygienists' job expectation, were indicated to fail to meet job expectation.

Present study conducted surveys and interviews to identify a solution to the issues concerning the work conditions, job satisfaction, and operational systems of archivists working in the Korean government agencies. Job characteristics were measured using the five-factor structures of Hackman and Oldham's(1976) Job Characteristic Models, professionalism, role conflict, stress, and turnover intentions. Job environment was measured in terms of communication, participation, social relations with coworkers and superiors, and job training. Job satisfaction was measured by general level of satisfaction, job meaningfulness, and commitment. Operational systems was analyzed in terms of organizational arrangement, role assignment, personnel management, and collaboration between the national archives and record centers. These analyses produced further implications and suggestions on personnel management of archivists and records managers.

The purpose of this study was to grasp the relationship among general characteristic, work characteristic, job stress and social psychological stress by targeting dental hygienists in a certain area. By using self-administered questionnaire, it was possible to get following results from 219 people. The total score of job stress of dental hygienist was $47.41{\pm}7.46$. The people who are younger, take lower positions at their workplace and not married showed higher stress about physical environment, autonomous work and improper compensation. The people with lower income showed higher stress about autonomous work and the people with lower academic background showed higher stress about physical environment and autonomous work. The people who spend more time at their workplace showed higher stress about autonomous work and showed lower stress about relational conflict, organization system, improper compensation and work culture. The job stress about physical environment, job request, autonomous work, unstable work, improper compensation and workplace culture had a positive correlation with social psychological stress. It was found that unstable work, organization system, improper compensation and higher position gave effects to social psychological stress.

The most difficult and time-intensive issue in the successful implementation of genetic algorithms is to find good parameter setting, one of the most popular subjects of current research in genetic algorithms. In this study, we present a new efficient experimental design method for parameter optimization in a genetic algorithm for general job shop scheduling problem using the Taguchi method. Four genetic parameters including the population size, the crossover rate, the mutation rate, and the stopping condition are treated as design factors. For the performance characteristic, makespan is adopted. The number of jobs, the number of operations required to be processed in each job, and the number of machines are considered as noise factors in generating various job shop environments. A robust design experiment with inner and outer orthogonal arrays is conducted by computer simulation, and the optimal parameter setting is presented which consists of a combination of the level of each design factor. The validity of the optimal parameter setting is investigated by comparing its SN ratios with those obtained by an experiment with full factorial designs.

In developing a regression relationship for a standard data system in work measurement, job characteristics are frequently measured with error when measurements are made in the field under less controlled conditions or when accurate instruments are not available. This paper concerns with the prediction of the total task time when job characteristics are measured with error. Integrated mean square error of prediction(IMSE) is developed as a measure of the effect of errors in job characteristics on the predicted total task time. By evaluating how IMSE is affected by the measurement error in each job characteristic, we can determine which error should be controlled to develop a desirable standard data system.

The purpose of this study was to identify the effect of job characteristics, job performance and organizational commitment on job satisfaction of hospital dietitians. The first survey was carried out on 74 hospital dietitians to determine their demographic characteristics, job characteristics, organizational commitment, and job satisfaction. The second survey was carried out on 47 hospital foodservice dietitians to determine their job performance. Thirty-two percent of the subjects were aged between 26 and 30, and 62.2% had Bachelor's degrees. The dietitians felt most satisfied by their co-workers, followed by the work-itself, supervision, pay, and promotion possibilities. Dietitians who had a higher education were satisfied with pay and supervision. The longer the length of employment, the more the satisfaction with the work-itself and pay, plus the higher the monthly wage the more the satisfaction with the work-itself, pay, supervision, and co-workers. lob satisfaction was high in the group that scored high on autonomy, feedback, task identity, and friendship of in the job characteristic inventory. The job performances of nutrition counseling(r= 0.469, p < 0.01), nutrition education(r= 0.446, p < 0.01) and management of therapeutic diet(r= 0.394, p < 0.01) were positively correlated with job satisfaction. The $R^2$for the multiple regression model was 0.677, indicating that 67.7% of the variance in job satisfaction could be accounted for by feedback, organizational commitment, nutrition counseling performance, and nutrition education performance. In conclusion, the level of job satisfaction for hospital dietitians would appear to improve with increased feedback, organizational commitment, and opportunity for nutrition counseling and nutrition education.
