This study was investigated the marital satisfaction of expanding dual-earner couples and it’s influential variables. The sample consisted of 226 husbands and wives in dual-earner families living in Seoul. The data were analyzed by various satistical methods such as Frequency, Percentile, One-way analysis, t-test and Multiple Regression Analysis. The results of this research were as follows: 1. The level of marital satisfaction was higher for husbands than wives. 2. Husbands’marital satisfaction was significantly affected by husbands’age, husbands’sex role attitude, wives’occupation, flexibility of wives’work. 3. Wives’marital satisfaction was significantly affected by husbands’income, husbands’sex role attitude, husbands’participative times of household labor and wives’participative time of household labor.

In this study, we investigated the characteristics of labor of water management and maintenance, water requirement, water quality(T-N, T-P, COD) in the paddy plot irrigated by pipeline with two types of hydrants: automatic and manual. The automatic hydrant have been introduced to the paddy field to save water and reduce the labor for water management. The automatic hydrant is automatically opened and closed according to the water depth of a paddy plot. The automatic hydrant generally developed more troubles than the manual hydrant. The water requirements are 2.7mm/d for the automatic hydrant plot and 17.6mm/d for the manual hydrant plot. The concentrations of pollutants in the two plots are higher in the ponded water than in the irrigation water and are highest after fertilizer application.

Although the Pontryagin's maximum principle theory is widely applied in control problems, its contribution to the solution procedure have been restricted just to figure out the rough picture of true solutions, probably due to the complexity of the two-point boundary value problems. This paper discusses a numerical approach to solve the control problems in connection with the two -point boundary value problems. A model of labor management negotiation during a strike has been constructed and solved explicitly by us of DVCPR subroutine introduced in IMSL. The results have been turned out that the management is better increase wage very slowly during the strike period, while , on the labor side, it is more effective to show the high intensity of demonstration against the company at the outset and gradually decrease it.

It compared subcontractor with contractor that are wages, the labor hour and labor condition of the work environment back are inferior relative. The subcontractor which basically the contract workers evade the dangerous process or the difficult work, the dirty work back what is called 3D the case which does to keep a business is many. so With life it will be threatened consequent health directly. The possibility where the subcontractor will be exposed to danger work came to be high. Consequently it prevents the subcontract which danger work is insensitive from this research and immediacy of the subcontract workers who is weak hygiene circumstance complement the plan it will be able to secure the immediacy safety&health subcontract workers, substantially to prepare in the hazard subcontract proprietor. Thus, this paper aims at presenting countermeasures to substantially secure safety and health of subcontractors by preventing ill-advised subcontracting of harmful and hazardous operations and imposing partial occupational safety and health responsibility to employers to enhance safety and health environment of subcontractors.

Scheduling of dismantling old research reactor need to consider time, cost and safety for the worker. The biggest issue when dismantling facility for research reactor is safety for the worker and cost. Large portion of a budget is spending for the labor cost. To save labor cost for the worker, reducing a lead time is inevitable. Several algorithms applied to reduce read time, and safety considered as the most important factor for this project. This research presents three different dismantling scheduling scenarios. Best scenario shows the specific scheduling for worker and machine, so that it could save time and cost.

사업의 지속적인 성장을 위해서, 생상성의 향상은 필수적인 요소이다. 건설업은 노동집약적인 산업이고 그래서 건설기능인력은 생산성에 영향을 미치는 가장 중요한 요인이다. 그러나 매해 건설기능인력은 감소하고 있는 추세이다. 따라서 이러한 문제는 반드시 교육체계와 직급체계의 제안을 통해 관리되어져야 한다. 이 연구의 목적은 기존의 문헌고찰을 통하여 현재의 교육체계와 직급체계의 연관된 문제를 찾아내고 이러한 문제를 해결하기 위하여 교육체계와 직급체계를 제안하는데 목적이 있다. 또 이러한 교육체계와 직급체계의 타당성 검증을 위하여 건설 기능 인력의 설문조사와 건설 실무자의 면담, 조사를 통하여 타당성을 도출해낸다. 좀 더 세부적인 사항이나 결론은 아래의 글에서 알아보기로 한다.

After Asian financial crisis hit the Korea, Korean government and Korean firms need to restructure their system. Specially financial sector has to renew its system. One way renew its system was adjust company's labor system. The forms of labor adjustment are external numerical flexibility, externalization, internal numerical flexibility, functional flexibility and wage flexibility. These five forms based on two big categories which are wage flexibility and employment flexibility. This study only focus on th effect of employment flexibility in financial sector in Korea. Employment flexibilities can be practice as employment adjustment. Also we concentrate on separation and re-accessors to other financial institute after the separation. The result shows that Korean financial sector are in the range of 10.78% and the job destruction rates are about 11.26%.

Interest about the effect of military service is increasing because of the renewal of military service incentive system in Korea. In the background, men has been experienced which suffer monetary and non-monetary damages through the compulsory military service in Korea. However there are few studies that analyze the labor market effect of military service. This study takes advantage of male worker's data of 10th KLIPS(Korea Labor & Income Panel Survey) in 2007 and analyze the wage effect of military service. According to empirical result using Mincerian earnings function, the positive effect of military service appeared. These result shows men who finished military duty have an monetary advantage in Korean labor market unlike general perceptions on military service.
