This research is a case study about the personnel management policy of Bachae co., Ltd. Bachae Co., Ltd. suggests as a successful model that by implementing the pro-active personnel management strategy eliminated the seniority, age-limit, academic snobbism, the qualities critical for managerial success are leadership, motivation, decisiveness, flexibility. It gives a solution especially to medium-sized companies suffering the manpower shortage, that the adequate motivation through strong leadership to employee results in not only job satisfaction but also organization absorption. The fact that company care about even the failure staying at their jobs longer without hurting their self pride to be loyal employee is a very demonstrative and great method which motivates middle & midium size of companies how to manage and utilize the human resources.

We investigate the scheduling problem for periodic job shops with blocking. We develop Petri net models for periodic job shops with finite buffers. A buffer control method would allow the jobs to enter the input buffer of the next machine in the order for which they are completed. We discuss difficulties in using such a random order buffer control method and random access buffers. We thus propose an alternative buffer control policy that restricts the jobs to enter the input buffer of the next machine in a predetermined order. The buffer control method simplifies job flows and control systems. Further, it requires only a cost-effective simple sequential buffer. We show that the periodic scheduling model with finite buffers using the buffer control policy can be transformed into an equivalent periodic scheduling model with no buffer, which is modeled as a timed marked graph. We characterize the structural properties for deadlock detection. Finally, we develop a mixed integer programming model for the no buffer problem that finds a deadlock-free optimal sequence that minimizes the cycle time.

This study estimates the influence of organizational-level factors on work motivation and job performance of middle managers of small and medium enterprises (SMEs) in Vietnam. A 5-point-Likert-scale structural questionnaire consisting of 36 observation variables was used to survey middle managers of Vietnamese SMEs. 425 out of 500 responses collected were valid for multivariate data analysis. The results of confirmatory factor analysis and structural equation modeling reveal three main findings. First, philosophy and policy, compensation and benefits, goal system, and leadership have positively significant impacts on the work motivation of middle managers under investigation. Second, there is a significantly positive influence of work motivation on job performance. However, there is no indication that growth opportunities, work environment, evaluation system have significant impacts on the work motivation of respondents. Based on the findings, the study suggests four recommendations for Vietnamese SMEs to improve motivation and job performance of middle managers, which are (1) ensuring the clarity and soundness of the organizational policies and philosophies, especially human resources policy that boosts employees' work motivation; (2) building a comprehensive compensation and benefit system to attract and retain talented employees; (3) developing a clear and adequate goal system; (4) enhancing top-level managers' leadership abilities.

Recently, honorary retirement is spreading like a fashion among teachers. This was due to rapid environmental changes and stress. Therefore, in this study, we examined the relationship between teachers' stress and job exhaustion. The study was conducted for middle school teachers in Changwon city. The results of this study were as follows: First, job stress of middle school teachers affected emotional exhaustion. Second, job stress of middle school teachers had an effect on impersonation. Finally, job stress of secondary teachers did not affect the reduced individual achievement. The results of this study suggest that job stress of middle school teachers is closely related to job exhaustion. Therefore, it is urgent to improve the administrative simplification based on the analysis of the teacher 's stress factors and the immersion into the class.

This study analyzed the effects of job characteristics and empowerment on job satisfaction of ERP system users of small/medium manufacturing & service businesses. In the results of analysis, the detailed factors of job characteristics such as efficiency, authority delegation, and complexity were significant influence factors on ERP users' job satisfaction while the factors of empowerment such as task impact, self-determination, and task meaning had positive effects on users' job satisfaction. However, competence did not have positive effects on job satisfaction. The results of this study showed that most of the ERP system users of small/medium businesses were satisfied with their own jobs.

This study aims at examining the extent to which older people participating in the Seniors' Job Programme do involve in policy-making and implementation processes of the programme. The study is based on qualitative interviews with seven experts among those involved in the policy process in District A of Seoul. They include civil servants of central and local governments and social workers of implementing bodies such as seniors' welfare centres and job centres. The results show that firstly, practically no direct involvement of participants is being made at the policy-making level, due mainly to the traditional top-down approach of policy process in Korea and also to prejudices of public servants concerned on the current senior citizens' capability as contributor to public policy-making. User-involvement is being made, however, at the implementation level: participants are making, although minor, suggestions for improvements of working conditions and they are being listened to by frontline social workers. Support by the implementing institutions turns out to be necessary for this. Lastly, in contrast with the present, many interview participants are expecting a more active participation from the future generation, i.e. the baby-boom generation when they would have retired. The study concludes by calling for enhancement of institutional and capacity-building support for active user involvement in the future.

The main objective of this study was to investigate how people prepare for old age by looking at financial statements from single-person households in Gyeonggi province; the policy implications regarding low fertility and population aging are considered. The subjects were members of 600 households who were aged 26 to 44 years old and not married. The data were analyzed by t-test, ANOVA, and dichotomous logistic regression using SPSS WIN 12.0. Respondents pointed out that financial problems are the greatest challenges for those facing old age in single-person households; they said that a stable job is the most important factor for secure living. About 57% of household residents responded that they have prepared for retirement, and a majority of them said they hoped to spend their elderly years with a marriage partner. The financial statements from single-person households were inferior to those from other types of households. The assets of single-person household members were less than those of other households. Only 10.5% of respondents have owned homes. The study discusses policy implications for those who want marriage and for those who don't want it. For those who want marriage, job-seeking support was proposed, and for the others, tax deductions and family programs for single-person households were proposed.

we model communication and computer systems that process interactive and several and several types of background jobs. The scheduling policy in use is to share the processor among all interactive jobs and, at most, one background job of each type at a time according to the process sharing discipline. Background jobs of each type are served on a first-come-first-served basis. Such scheduling policy is called Processor Sharing with Background jobs (PSBJ). In fact, the PSBJ policy is commonly used on many communication and computer systems that allow interactive usage of the systems and process certain jobs in a background mode. In this paper, the stability conditions for the PSBJ policy are given and proved. Since an exact analysis of the policy seems to be very difficult, an approximate analytic model is proposed to obtain the average job sojourn times. The model requires the solution of a set of nonlinear equations, for which an iterative algorithm is given and its convergence is proved. Our results reveal that the model provides excellent estimates of average sojourn times for both interactive and background jobs with a few percent of errors in most of the cases considered.

This study was conducted to obtain meaningful information about job management of child care center teachers, who take charge of child care policy at the front line, social meaning of which is being greatly highlighted these days. Especially, the research was designed with causal relationships in mind, in which certain job-related thoughts or consciousness forms attitudes, thus leading to behavior. In this light, the present study selected the following variables for analysis: job attitudes including job calling, job engagement, and job burnout; and job behavior such as creative behavior, active behavior, and ethical behavior. Data collected from 209 child care center teachers' response to structured questionnaires was analyzed, using t-test, one-way analysis of variance (one-way ANOVA), and hierarchical regression analysis. The results indicate that job burnout increased at a statistically significant level as extra workhours increased, and that only job engagement, among job attitude variables, and creative behavior and active behaviors, among job behavior variables, had significant effects. Moreover, job engagement was the only variable that was found to work as a mediator in relationships between job calling and active behavior.
