This study aims to develop a curriculum for nurturing experts who perform agricultural safety and health management tasks. This study was conducted in three stages. First, job definitions and job models of agricultural safety and health managers were derived through job analysis using the DACUM technique. Second, job demand analysis was conducted by conducting a survey on the difficulty, importance, and frequency of each task. Third, IPA analysis was performed as the first priority tasks of job demand analysis to present the courses and subjects of the training course for safety and health managers in agricultural work. The job of the agricultural safety and health manager was defined as "to conduct guidance and advice on safety and health education, risk factors, and evaluation and management of harmful factors to protect farmers' professional health and safety." The job model consisted of 4 tasks, 31 core tasks, and 67 detailed tasks. As a result of job demand analysis, there were 39 tasks in the 1st priority, 22 in the 2nd priority, and 6 in the 3rd priority. As a result of the IPA analysis, there were 13 'capacity development focused areas', 4 'capacity development effort areas', 11 'low priority areas', and 3 'continuous maintenance areas'.

반도체 제조공정에 내재된 복잡성은 작업일정(job scheduling) 문제를 해석적 방법으로는 풀기 어렵기 때문에 보통 시스템 파라미터의 변화에 대한 효과를 이산사건 모델링 시뮬레이션에 의존하여 왔다. 한편 장비 고장 등 예측 불가능한 사건들은 고정된 작업일정 기법을 사용할 경우 전체 공정의 효율을 악화시킨다. 따라서 이러한 불확실성에 대해 최적의 성능을 내기 위해서는 작업일정을 실시간으로 대처 변경하는 것이 필요하다. 본 논문은 반도체 제조 공정에 대해 시스템 제어관점의 접근방법을 적용하여 이 문제에 적응형 실시간 작업제어 틀을 제안하고, DEVS 모델링 시뮬레이션 환경을 기반으로 제안된 틀을 설계 구현하였다. 제안된 방법은 기존의 임기응변적인 소프트웨어적인 방법에 비추어볼 때 전체 시스템을 이해하기 쉬우면서도 또한 추가되는 작업제어 규칙도 쉽게 추가 적용할 수 있는 유연성을 장점으로 가지고 있다. 여러 가지 실험결과 제안된 적응형 실시간 작업제어 프레임워크는 고정 작업규칙 방법에 비해 훨씬 나은 결과를 보여주어 그 효용성을 입증하였다.

Recently, the military service period has been shortened continuously. Meanwhile, more skilled airmen are needed as the complexity of weapon systems increase. This phenomenon could lead to a disastrous result such as deteriorating the level of the readiness and the fighting power. We suggest a method to improve recruit's maintenance capability rapidly by assigning airmen to jobs appropriate to their characteristics using Datamining methods (K-menas and CART). We focus on the assigning method for air force's air-munition maintenance airmen since they are requested more skilled than other airmen. Grouping airmen with k-means method and devising classification rule with CART algorithm, we found that airmen's proficiency arrival period could be shortened by 1.79 months when they are assigned in the suggested way.

The purpose of this study is to predict the roles of public social workers and clarify their job. There were a few studies concerning them, and they suggested that it was needed to reform the delivery system or to supplement personnel. But they were almost normative. This study, based on the literature, analyzed public social workers' daily works to suggest their desirable roles. Generally the job of public social workers consists of two functions. One is income maintenance function, the other is social services function concerned with economically disadvantaged. The result showed that these functions were meshed up to now. Especially, It also showed that although they performed mostly eligibility work related public assistance and general practices, they wanted to perform professional practices. Took into account their working conditions, it seemed to be desirable to clarify their job. Thus, several suggestions based on these results are as follows: First, while eligibility functions are the central aspects of the public social worker's roles, it is needed for them to provide selected access services. Second, if they wanted to perform social services, it would be needed to restrict their roles for case manager and broker.

Developed countries that have experienced decline in productivity due to the economic crisis in the past have come to recognize the smart factory as an important means to strengthen the competitiveness of the manufacturing industry due to the increase in labor costs, the avoidance of the manufacturing industry, and the resolution of the shortage of skilled manpower. The necessity of nurturing manpower for self-maintenance was felt through identifying factors for successful smart factory introduction by companies and providing smart factory education. Therefore, the effects of educational satisfaction and operational competency on self-efficacy as a parameter and self-efficacy as a parameter were analyzed using research models and hypotheses to determine whether there was an effect between job satisfaction as a dependent variable. As a result of the analysis, it was found that the mediating effect of self-efficacy and self-efficacy on job satisfaction was found to have significant effects on operational competency and self-efficacy as parameters, as well as educational satisfaction and operational competency. The implication of this study is that continuous education and innovation activities are important in order to increase the business performance of companies, and through this, the manufacturing competitiveness of SMEs can be improved.

Purpose of the study was to identify the relationship between job stress and health promoting behavior(HPB) among nurses. Samples were 426 nurses working in some university hospitals which were chosen by convenient sampling. Data was collected by using constructed questionnaires from March 28th to April 7th 2001. The instruments used for in the study were 'The Health Promotion Behavior' which was developed by Park(1995) and 'The Job Stress' modified by Kim(1998). The data was analyzed by mean, standard deviation, t-test, ANOVA, Duncan test and Pearson's correlation coefficient in the SPSS program. The results were as follows : 1. The mean score of job stress was 3.51 which is meant to be 'more than moderate' level of stress. 2. The total mean score of health promoting behavior was 2.44; 'Management of Sanitary life' 3.12, 'Harmonious relation-ships' 2.95, 'Emotional support' 2.71, 'Diet control' 2.59, 'Self-achievement' 2.57, 'Self-control' 2.31, 'Healthy diet' 2.29, 'Rest and sleep' 2.26, 'Exercise and activity' 2.12, 'Regular diet' 1.91 and 'Professional health maintenance' 1.61 were shown in each HPB category. 3. There were not any statistical differences between job stress and general characteristics of nurses. 4. The health promoting behavior was significantly influenced by factors of age, marital status, education level, religion, position, career and family income of nurses. 5. There was not any correlations between job stress and health promoting behavior.
