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.

This study tried to identify the job stress characteristics of female bank workers and the relationship between their stress and symptoms associated with musculoskeletal disorders(MSDs). The total number of 587 female bank tellers have been participated in this study. Specifically, questionnaire surveys regarding job stress and MSDs symptoms were conducted. On the basis of the results from the survey using Korean version of job stress questionnaire with 24 questions, stress scores associated with job requirement and job flexibility were relatively high. The job stress levels regarding job demand, organizational system, occupational climate at the work place were relatively high for the full time workers while the job stress levels regarding insufficient job control, job stability, interpersonal conflict, lack of reward were relatively high for the part time worker. The workers with longer total work years had relatively high job stress associated with interpersonal conflict, and organizational system while the workers with longer work years at the current job had relatively high job stress associated with occupational climate. Also, the workers with longer working hours a day had relatively high job stress associated with job demand, interpersonal conflict, organizational system, and occupational climate. According to the relationship identified in this study, symptoms at the neck, shoulder, hand, low back. leg were associated with the stress levels in terms of job flexibility, interpersonal conflict, job requirement, job stability. In conclusion, female bank workers are exposed to job stress due to their specific job characteristics and there has been certain relationships between their job stress and MSDs symptoms.

Although there are numerous studies that address the problem of optimal machine grouping and part family classification for cellular manufacturing, little research has been reported that studies the conditions where cellular manufacturing is appropriate. This paper, in order to evaluate and compare the job shop with the GT cellular shop, the performance of those shops were simulated by using SIMAN. We tested the effect of independent variables including changes of product demands, intercell flow level, group setup time, processing time variability, variety of material handling systems, and job properties (ratio of processing time and material handling time). And also performance measures (dependent variables), such as machine utilization, mean flow time, average waiting time, and throughput rate, are discussed. Job shop model and GT cellular shop written in SIMAN simulation language were used in this study. These systems have sixteen machines which are aggregated as five machine stations using the macro feature of SIMAN. The results of this research help to better understand the effect of production factors on the performance of cellular manufacturing systems and to identify some of the necessary conditions required to make these systems perform better than traditional job shops. Therefore, this research represents one more step towards the characterization of shops which may benefit from cellular manufacturing.

이 글에서는 2000년대 중반 이후 한국의 임금불평등을 지니계수의 변화와 이를 초래한 요인들의 기여도를 분석하였다. 자료와 임금 지표에 따라 추세가 달라지지만, 주당 35시간 미만 일하는 파트타임의 증가로 전체근로자 임금총액의 지니계수는 증가하는 추세를 보여주는 반면, 시간당임금 지니계수와 풀타임근로자의 임금총액 지니계수는 하락하는 추세를 나타냈다. 파트타임 증가가 임금총액 기준의 불평등은 높였지만, 파트타임의 시간당임금 증가는 시간당임금 기준의 불평등을 낮추었다. 풀타임 노동자만을 대상으로, 지니계수 감소 요인을 분해한 결과, 불평등 감소에 절대적으로 기여가 큰 요인은 근속, 경력, 직종 등의 변수였고, 고용형태 변수는 불평등 감소에 미미하게 기여하는 것으로, 사업체 규모 변수는 불평등을 오히려 높이는 것으로 나타났다. 업종이나 연령, 교육 등의 변수는 불평등 변화에 유의미한 크기의 기여를 하지 못한 것으로 분석되었다. 여기에는 장기근속과 관리전문직종에 대한 임금프리미엄의 감소와 대규모사업체의 임금프리미엄 증가 등이 작용한 것으로 분석되었다.

The purpose of this study is developing scheduling logic and program for machining scheduling of automobile part production line with unbalanced processing time. Three rules are developed to minimize slack and effect on other job. Fourth rule is suggested which considered weighted sum of three factors. schedule is generated totally 1, 000 times and then optimal weight parameter is selected. The program is developed to schedule situation to compare with the performance measure, total finish time of machine and total tardiness of part. As a result, the rule which considered weighted sum of three factors is effective for both measure.

This study aims to analyze teachers job satisfaction according to the working environment of teachers working in child-care centers and to investigate which variables of the working environment relate to job satisfaction of child-care teachers. The main results of this study were as follows. First, married teachers are more satisfied with the job itself, supervision, and colleague relations compared to teachers who are not married. Teachers with certificates are more satisfied with the job itself compared to teachers without certificates. Second, teachers's job satisfaction is significantly correlated with their salary, welfare, and colleague relations. Also teachers' job satisfaction is correlated with responsibility in the case that teachers have a good relation with their principal and child-care parents. Third, the results of this study show that teachers consider substitute teachers, vacation systems, day care systems, compliant with the ratio of teacher and children, job security, order of legal status as important. With regard to external compensation, teachers want salary increase, payment on overtime labor, flexible work-time, use of both full-time and part-time teachers, expansion of educational materials, increase on purchasing cost for textbooks and materials. To improve the quality of child-care teachers' working environment as well as their satisfaction, practical policies need to be implemented.

In the era of 'Untact', virtual reality-based job training platforms are actively being used as part of non-face-to-face education for students with developmental disabilities. Because the people with developmental disabilities may lack sufficient cognitive abilities, it is difficult to conduct untact training seamlessly without the help of a third party. Therefore, it is necessary for training programs to identify the right timing to provide help so that the training can be continued. This research analyzed the visual attention of students with developmental disabilities in virtual reality-based job training program in order to determine the point of time when an intervention is required by the trainee. Results showed that students who completed the mission tended to have intense visual attention on a small number of objects for a certain period of time; the visual attention of the students who failed tended to shift erratically among multiple objects.

The purpose of this study is to survey job stress and Musculoskeletal Disorder(MSDs) of workers in small plants with agricultural products. The subjects were comprised of 69 workers participated in "Helping the rural women to get the small businesses" project. The questionnaire surveys were Korean Occupational Stress Scale(KOSS), and Legal Risk Assessment of Musculoskeletal Disorders(KOSHA CODE H-30-2003). As a result of the survey, scores of KOSS 8 sub-items except for job demand were similar to that of Korea workers. Prevalence of MSDs symptoms of small plants workers was high percent (44.9%). And the rate according to kinds of product was significant difference at neck (p<0.01), lumbar (p<0.01), and leg (p<0.01). There was no significant difference between view person sign of MSDs and non MSDs according to sex, year, the number of workers, working years, working time per one day, rest time per one day, and subjective working intensity, but there were significant difference between high stress group and low stress group about MSDs at interpersonal conflict(p<0.05). Job stress and MSDs were important factor to workers of small plants producted agricultural products. Therefore, starting a business with small plats, workers consider interpersonal conflict and body part showing MSDs.

본 논문은 파트타임근로를 통해서 짧은 시간 내에 높은 고용률 향상이라는 성과를 달성한 네델란드에서의 파트타임근로의 현황과 전망, 제도와 정책 등을 종합적으로 살펴보는 글이다. 네델란드는 파트타임근로를 통한 고용률 제고뿐만 아니라 양질의 파트타임을 만들어냈다는 점에서 주목받고 있다. 네델란드에서 파트타임근로가 증가한 것은 시장, 제도, 정책, 그리고 노사관계 등 다양한 요인들이 파트타임근로를 촉진하는 방향으로 서로 보완하면서 발전하였기 때문이다. 노동시장에서는 여성의 경제활동참가 증가와 기업의 파트타임수요의 증가라는 선순환 구조가 형성되었고, 파트타임근로를 보호하고 파트타임에 유리하도록 인센티브 구조를 재설계하며 근로시간선택권을 보장하며 보육시스템을 강화하는 제도나 정책이 지속적으로 강화되었다. 그러나 이러한 시장에서의 수요-공급의 선순환 구조와 파트타임을 촉진한 제도와 정책도 노사정 사이의 사회적 합의라는 커다란 틀 속에서 그에 기초해서 이루어진 것이었다는 점이 중요하다. 또한 거의 30년 가까지 지속된 네델란드모델은 노동시장의 문화와 관행으로 정착되어 풀타임근로나 노동시간 확대의 방향으로 전환하기는 어려운 것으로 평가된다. 따라서 네델란드 모델은 네델란드의 사회적 조건 하에서 성립한 특수한 모델이고 높은 수준의 사회적 합의를 기초로 하여 제도와 시장이 보완적으로 잘 결합되어 있는 모델이기 때문에 여타 국가가 부분적인 제도 이식을 통해서 성과를 내기는 어렵다고 판단된다.
