The purpose of this study is to identify the influence of the high performance and the work system recognized by the organizational members participating in the NCS enterprise utilization consulting on the organizational effectiveness and the influence of the organizational performance. In order to achieve the purpose of this study, the research hypotheses were verified by applying multiple regression analysis and co-integration regression analysis on the 145 usable results from using the statistical program of SPSS 24.0. The results of this study are as follows. First, hypothesis 1, the analysis of positive(+) influence on organizational effectiveness on the characteristics of the system (selection system, evaluation and compensation, education and training opportunity, member participation system, job stability) was adopted due to its' positive(+) and significant relationship. Second, hypothesis 2, an analysis that the organizational effectiveness would have a positive impact on organizational performance was adopted due to its' proven work. However, its' effectiveness will need verification. Third, regression analysis was conducted to confirm the role of the hypothesis 3, personnel management effectiveness, between the high performance and the work system (selection system, evaluation/compensation, education/training opportunity, member participation system, job stability). As a result, Hypothesis 3 showed that the selection system (H3-1), evaluation and compensation(H3-2), education and career opportunities(H3-3), member participation system(H3-4), job stability(H3-4) showed that organizational effectiveness has a moderating role in HR effectiveness. The main implication of this study is that the positive and working system recognized by the organizational members has positive affects on organizational effectiveness and organizational performance. In order to enhance the substantiality management system through improvement of organizational performance, a regular implementation plan on a high-performance working system along with education & training system to improve organizational effectiveness is required so that the members of the organization could form a consensus. Second, as a result of confirming the moderating effects of HR management effectiveness, the moderating role of HR management system and organization effectiveness was verified positive. Therefore, this study shows that the part that verifies both organizational effectiveness and organizational performance through high-performance working system and the part that confirmed the role of control between high-performance work system and organizational effectiveness are the biggest difference from the previous research.

The chaperone practices is being applied to solve the problem of sexual harassment in clinics in medical institutions. Therefore, considering the characteristics of the radiation work and the application of the chaperone practices in the radiation work, this study is to analyze the requirements for the application of the chaperone practices and the impact that may occur on the job. From the end of 2021 to the beginning of 2022, a survey was conducted targeting radiologists in Daegu and Gyeongbuk, and about 52.9% of the surveys were analyzed. As a result of the analysis, the demand for the application of the chaperone practices was higher among women than men, the younger the age, the higher the degree, and the lower the age. Also, as for the job impact of the application of the chaperone practices, the higher the demand, the greater the reduction in sexual harassment and credibility. In other words, the younger the age and the higher the education, the higher the need for the chaperone practices, but it is thought that it is necessary to supplement the policy for job security and Employment stability before applying it. Therefore, when considering the application of the chaperone practices to radiation work in the future, it is judged that it is necessary to sufficiently collect opinions in advance to guarantee the job in the relevant occupation.

This paper describes the Flight Dynamics Automation (FDA) system for COMS Flight Dynamics System (FDS) and its test result in terms of the performance of the automation jobs. FDA controls the flight dynamics functions such as orbit determination, orbit prediction, event prediction, and fuel accounting. The designed FDA is independent from the specific characteristics which are defined by spacecraft manufacturer or specific satellite missions. Therefore, FDA could easily links its autonomous job control functions to any satellite mission control system with some interface modification. By adding autonomous system along with flight dynamics system, it decreases the operator's tedious and repeated jobs but increase the usability and reliability of the system. Therefore, FDA is used to improve the completeness of whole mission control system's quality. The FDA is applied to the real flight dynamics system of a geostationary satellite, COMS and the experimental test is performed. The experimental result shows the stability and reliability of the mission control operations through the automatic job control.

This paper examines the changes in early reemployment bonus system in Korea and investigates its effects on job finding rates of the unemployed and on their reemployment outcomes. The analysis on the characteristics of the recipients reveals that, after the policy change, the probability of receiving the bonus increases among female, older, and less educated job seekers. This paper also shows that exit hazard from unemployment has not changed significantly while the stability of the subsequent jobs has been substantially improved.

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.

Semiconductor research and development(R&D) fabs are very different than production fabs in many ways such as the scales of production, job priority, production methods, and performance measures. Efficient operations of R&D fabs are very important to the development of new product, process stability, high yield, and ultimately company competitiveness. This paper proposes the fab-wide scheduling method for operational optimization of the R&D fabs. Most scheduling systems of semiconductor fabs have only focused on maximizing throughput of each separated areas without considering WIP(works in process) flows of entire fab. In this paper, we proposes the a fab-wide scheduling system which schedules all lots to entire fab equipment at once. We develop the MIP(mixed integer programing) model which allocates the lots to production equipment considering many constraints of all processes and the CP(constraint programming) model which determines the sequences of the lots in the production equipment. The proposed FAB-wide scheduling model is applied to the newly constructed R&D fab. As a result, we have accomplished the system based automated job reservation, decrease of the hot lot delay, increase of the queue time satisfaction, the high throughput by maximizing the batch sizes, decrease of the WIP TAT(Turn Around Time).

The purpose of this study was to examine how sociodemographic status, family-related influences, and perceived future economic prospects were associated with the possibility of getting married and having children in a sample of 607 single young Korean adults. The sample comprised unmarried men and women in their 20s and 30s taken from the 2021 Seoul Family Report survey, and descriptive statistical and multiple regression analyses were conducted on the data. The results indicated that age, non-traditional marriage/childbearing values, parents' marital relationship during childhood, and the prospect of having a stable job and owning a home were significantly related to the possibility of marriage. With regard to the possibility of having children, a significant relationship was found with age, level of education, non-traditional marriage/childbearing values, recognition of the importance of family, parents' marital relationship during childhood, and the prospect of having a stable job and owning a home. The study also examined the importance of policies that make the possibility of marriage and having children more appealing to young unmarried adults in Korea by providing a positive outlook for the economy, a sense of stability, and a supportive approach to the value of having a family.

This study examines attitudes among nursing student, attitudes that give direction in life and effect the decision-making process when seeking employment. The exigency of which derives from the need to design a proper guidance program to assist students in their search for employment. Data was collected from a survey conducted between November 20 and November 25, 1995, the respondants of which were 120 nursing students without jobs. The data was analyzed by examining frequency, percentage, average, Chi-square, one-way ANOVA and t-test through an SPSS $PC^+$ program. The results of the study can be summarized as follows : 1) There are positive relationship between a student's academic major and employment(So responded 84.3% of the subjects with only 2.5% claiming that his major didn't matter). 2) Students believe that 'good jobs' are secured through aptitude. 'Good jobs' are seen as ones which develop an individuals abilities and which offer the opportunity for advancement. However they do not believe that 'good Jobs' contribute to society 3) Students have not been supplied the proper guidance and information necessary for finding employment. The student's life research institude, professor and assistants provide Insufficient information and counseling. Personal goals are decisive factors in determining what direction a student may take as well as the kind of employment he will seek. However, advice from parents, siblings, friends, alumni, professors, assistants and counselors is also considered. 4) Students do not think it reasonable to base their career decisions on one factor only(33.9% responded that aptitude and personal interests were the most important factor, and 14.9% that income was the key determinant). 5) Location and size of the hospital are important considerations when choosing a job. There is a preference for larger hospitals. 6) A lack of stability and few opportunities for advancement are perceived as the primary reasons for the possibility of leaving one's job.

This study tried to develop a basis for quantitative index of working postures associated with WMSDs (Work-related Musculoskeletal Disorders) that could overcome realistic restriction during application of typical checklists for WMSDs evaluation. The baseline data(for a total of 603 jbs) for this study was obtained from automobile manufacturing company. Specifically, data for back posture was analyzed in this study to have a better and more objective method in terms of job relevance than typical methods such as OWAS, RULA, and REBA. Major statistical tools were clustering, logistic regression and so on. The main results in this study could be summarized as follows; 1) The relationship between working posture and WMSDs symptom at back was statistically significant based on the results from logistic regression, 2) Based on clustering analysis, three levels for WMSDs risk at back were produced for flexion as follows: low risk(< $18.5^{\circ}$), medium risk($18.5^{\circ}{\sim}36.0^{\circ}$), high risk(> $36.0^{\circ}$), 3) The sensitivities on risk levels of back flexion was 93.8% while the specificities on risk levels of back flexion was 99.1%. The results showed that the data associated with back postures in this study could provide a good basis for job evaluation of WMSDs at back. Specifically, this evaluation methodology was different from the methods usually used at WMSDs study since it tried to be based on direct job relevance from real working situation. Further evaluation for other body parts as well as back would provide more stability and reliability in WMSDs evaluation study.

The purpose of this study is to investigate the structural relationships among frontline hotel employees' core-self evaluations (self-esteem, generalized self-evaluations, locus of control, and emotional stability) as personal resources, customer verbal aggression as a job stressor, and turnover intention as a job outcome. Data were gathered from a sample of frontline employees of 10 five-star hotels in Busan via self-administered questionnaires. A total number of 405 questionnaires were utilized. This study used structural equation modeling to verify the research model and hypotheses. As hypothesized, the results demonstrated that core-self evaluations reduced customer verbal aggression and turnover intention, and customer verbal aggression amplified turnover intention. Finally, practical implications were discussed in detail and limitations of the study and future research directions were also suggested.
