Rural youth welfare was defined to provide the preventive services as well as the protective and curative services such as education, job training, youth activity, delinquency prevention, etc. for rural youth who live in rural society, including who go out to metropolitan city for study. Based on this concept, the rural youth related facilities and problems were investigated in the area of education, culture and leisure, career, and problematic behavior. The results were identified that the efforts of government and rural related institutions were in sufficient to establish and improve the facilities for rural youth, and the gap between rural and urban youth facilities was extended increasingly, in spite of seriousness of those rural youth problems. Some of policies and programs were proposed in order to improve rural youth welfare; 1) To establish at least one activity facility in every Eup ; 2) To convert the public culture facilities such as museums, fine art museums, exhibition facilities, etc. into the culture and art facilities for rural youth; 3) To establish rural youth job information center in the agricultural technology and extension center; 4) To convert school to rural youth education and cultural center; 5) To establish the comprehensive welfare facilities for rural youth in metropolitan city.

Long-term care Insurance system for the Elderly was started to respond to the aged society on July 2008 in Korea. So responsibility of the care for the old is being changed from the family to the society. The introduction of that insurance system has brought the growth of demand for care service. To improve the level of quality for care service providers in long-term care, the role of care worker in providers is recognized as important. But welfare system for the care worker seems to be poor. So the Seoul Metropolitan Council is preparing an ordinance for the care worker and the purpose of this study is for the ordinance as well. Questionnaires, interviews, documentary surveys were used to carry out this study. The results of this study are summarized as follows. The job stability is the most important thing for the care worker, so local government has to make efforts to promote the job stability of care worker. A welfare center for care workers is needed for the health for care workers in the local government. And the local government has to supervise service providers more strictly and evaluate them in treatments of care worker.

Many dispatching rules have been developed for the on-line control of product flow in a job shop. The introduction of a flexible manufacturing system (FMS) has added a new requirement to classical job shop control problem : the selection of machines by parts of different types. An FMS can keep a great deal of information on the status of the system, such as information on what is scheduled in the near future, with great accuracy. For example, the knowledge of the time when the next part will arrive at each machine can be neneficial for the routing. This paper tests the effects of the use of this knowledge for part routing on the parts flow time (sum of the time for waiting and service) under a simple routing procedure- a look-ahead routing procedure. A test under many operating conditions shows that the reduction of part flow time from the cases without using this information is between 1% and 11%, which justifies more study on this routing procedure at real production sites when machine capacity is a critical issue. The test results of this paper are also valid for other highly automated systems such as the semi-conductor fabrication plants for routing when the arrivals of parts in the near future are known.

The purpose of this study was to explore the institutional protection scheme to identify the factors influence physician turnover of social workers. The main reference comes from the 2014 research on wages and work conditions of Korea Institute for Health and Social Affairs. The result of the analysis shows that 33.7% of the social workers intend to change jobs and that the possibilities of changing jobs have factors in gender, age, education levels, job satisfaction, wage, and contractual factors. This result shows that in order to enhance support of underprivileged, the treatment of social workers needs to be improved. This research proposes settings of switching job position system through facility M&A and institutional development.

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.

Purpose: To identify the importance and performance levels of health management duties, work-related and general attributes of health managers in medical institutions and analyze their impact on the performance of managing health-care related tasks. Methods: This research identified the performance levels of 150 health managers who have been executing industrial health-related duties for more than six months as nurses in medical institutions with more than 30 hospital beds. The variables which affect their performances were then analyzed. Results: The average importance of health care duties was 8.1 out of 10 and 5.5 for performance levels. Multi-regression analysis on the variables affecting performance levels of health managers in medical institutions showed that health managers exhibit higher numbers under the following conditions: over 300 full-time employees, more than 1 year but less than 3 years of experience, positions above section chief level, affiliation to the safety and health department, and high perception of duty importance. Conclusion: Improved cognizance of health manager importance should occur initially; then, health-care center setup, assigning of exclusive occupational health managers, and organizational efforts to improve the working environment in tandem with the provision of educational training programs to improve work quality are necessary.

This study was conducted with 375 workers in Changwon to examine the effects of working patterns on dietary habits and health. A self-administered questionnaire was conducted July 22 October 30, 2019. According to the results of the dietary habits and health related factors analysis, non-shift administrative workers showed significantly higher rates of green tea intake (p<0.05), and shift production workers showed significantly higher smoking rates (p<0.001) and waist circumferences (p<0.01). According to the results of the Pearson's correlation coefficient analysis, work hours showed negative correlations with job satisfaction (r=0.22, p<0.01) and positive correlations with perceived stress level (r=0.14, p<0.01). Temporary workers showed negative correlations with feel job satisfaction(r=0.14, p<0.01), perceived stress level (r=0.12, p<0.05), and concern about health (r=0.13, p<0.05). Diabetes showed positive correlations with hypertension (r=0.20, p<0.01), low HDL cholesterolemia (r=0.22, p<0.01), abdominal obesity (r=0.13, p<0.05), and hypertriglyceridemia(r=0.22, p<0.01). Based on these results, this researcher proposes that continuous attention and support of industries and communities are necessary for nutritional education and counseling relative to improving workers' dietary lives as well as disease prevention and control.

The purpose of this study is that problems caused by labor environment of cuisiniers in hotels need to be considered and studies regarding a part-time cuisinier in a special-grade hotel need to be conducted. This study analyzes the influence of labor conditions and organizational commitment of a part-time hotel cuisinier on duty satisfaction. It consists of two parts: a research based on the review of the literature and empirical study methods. The method of human resource management in hotels such as treatment of a part-time cuisinier in a special-grade hotel and the way of management as a result of an empirical study are proposed. First, as a result of conducting research on duty satisfaction to part-time cuisinier, most of them are highly satisfied with their duty regardless of their age and academic backgrounds. Second, men hold a majority; woman staffs tent to have a had time working overtime considering the situation that hotels run for 24 hours. That is the main reason why less woman staffs work in hotels than man staffs do. Part-time staffs would like to work consistently after they get upgraded to a regular worker. Forth, it is considered to break down into detailed sectors and speciality is highly demanded.

The purpose of this study is to suggest the grid search method for selecting an optimal decision tree model. It chooses optimal values for the maximum depth of tree and the minimum number of observations that must exist in a node in order for a split to be attempted. Therefore, the grid search method guarantees building a decision tree model that shows more precise and stable classifying performance. Through empirical analysis using data of job satisfaction of workplace reserve force commanders, we show that the grid search method helps us generate an optimal decision tree model that gives us hints for the improvement direction of labor conditions of Korean workplace reserve force commanders.
