제2차 세계대전 이후, 후진국의 폭발적인 인구 증가는 세계적인 근심을 야기했다. 하지만 출산율을 낮추려는 가족계획 사업의 효과는 이러한 정부 계획이 내생적으로 결정되기 때문에 측정하기 힘들다. 이 논문은 고정효과 모형을 써서 가족계획 사업의 출산율 저하에 대한 영향이 통계적으로 유의한지 밝혀내고자 한다. 고정효과 추정에 따르면 가족계획 사업이 출산율에 미치는 영향은 극히 미미하다. 그 중 1인당 소득이 높은 편인 국가들만이 유의한 음의 효과를 보여준다.

주5일 근무제도의 노동시장 외적 효과를 개인-일자리 고정효과 모형을 이용하여 추정한 결과 직장에서 주5일 근무제도의 실시는 근로자의 주관적 건강상태를 향상시키고 운동 횟수를 늘렸으며, 직업훈련 외의 교육이나 연수를 받을 확률을 늘리고 근로자의 주관적 삶의 질을 향상시킨 것으로 나타났다. 또한 문화 활동이나 여가에 사용하는 지출을 늘렸으며 근로자가 일과 직장에 대해 갖는 만족도도 높인 것으로 나타났다. 효과의 상당 부분은 단순한 근로시간의 단축보다는 휴일이 추가된 것에 기인한 것으로 추정되었다.

A study on the structural change in the U.S. textile industry. The U.S. textile industry has undergone significant changes over the last fifty years, including a steady decline in the relative scale of domestic production, employment reduction, and increased competition from imported products. In order to weather a crisis, the responses of the U.S. textile industry have been made such as investment in technology, specalization in the textile and apparel industries. The textile and apparel industries have taken steps to increase labor productivity through automations to speed management to create and introduce new products and new methods, and have lowered indirect overhead costs. Regarding these response of the U.S. and other situation of world textile and apparel trade market, much of the sense of crisis that pervades korean textile and apparel industries has to do with the problem of adjusting corporate policy.

Noise can make surrounding environments inferior and deteriorates operation efficiency, and it can bring aural damage as well as give a person psychological stress. Therefore, necessity of study about noise control is increased for better labor conditions and agreeable habitat. In this paper, implementation of active mufflers using active noise control techniques is presented. The LMS algorithm is used for adaptive filter algorithms. Computer simulations and experiments using TMS320C32 digital signal processor have performed to show the effectiveness of a proposed algorithm.

The purpose of this study is to review current home-based work study and identify factors associated with the choice of home-based work. Home-based work as an alternative form of employment is being sought today by both workers and business. The information age with its empasis on the recoding and transfer of information along with the technology of telectommuting has increased potential for and attention to home-based work. Home-based work seems to have several advantages particulary for women who carry the double burden of household work and paid work. The reduction in traffic congestion and demand of fossil fuels that accompanies the elimination of commuting has also been seen as a important social benifit. Home-base work has potential that can improve women's labor force participation. Further study is needed to evaluate home-based work and critical advice to current and prospect workers.

Characteristics of the motivation and performance of Enterprise Resources Planning (ERP) adoption in university organization are explored through case studies in this study. Generally, the modules for production, sales, and logistics management in a manufacturing company are substituted with new modules for student support, lecture operations, and research management in ERP for university organization. The motivation of ERP adoption is closely related to the purpose of improvement of business process operations and information system control rather than the environmental factors such as inter-organizational competition or increase of market uncertainty, differentially from enterprises cases. In addition, the financial performance such as cost reduction, labor substitution, and increase of productivity is relatively lower evaluated than the performance on organizational aspects or information system control.

Purpose - Transnational corporations (TNCs) have influenced drastic changes (financial services, manufacturing, labor, technology transfer) in Central Eastern Europe (CEE). This paper examines the indirect changes in the CEE pattern of industrial development and market distribution. Research design, data, and methodology - Over 25 years, neighboring (or rival) countries competed to attract TNCs as a double-edged strategy for privatization and debt reduction. Through their experience attracting foreign direct investment (FDI), many countries started to reflect aspects of national capitalism. Countries also began to realize in 2010 that TNCs sought to enter markets with more favorable conditions for export-oriented manufacturing. Results - The analysis reveals that TNC investment strategies were aimed at eliminating local competition to acquire industrial "brown fields" to convert into "green fields." CEE countries have since strengthened their national systems and the support of large-scale state-owned enterprises and small and medium-sized start-up enterprises. Conclusions - CEE has changed based on industrial development and a regional structure of TNC market distribution and associated government policies. The pattern toward flexible markets gives countries the ability to further their economies.

In order to improve the loading efficiency in bulk dryer for the flue-cured tobacco leaves, a new hanger device was developed. It consists of two layers frame, in which large volume of the harvested leaves could be simply loaded. As the results of experiments with new hanger device, labor hours for loading could be saved by 34 % as compared with those in conventional 3 layers hanger, and loading capacity increased by 36%. The weight of hanger could be also reduced by 0.6kg compared to conventional 3.4kg, showing possibility of cost reduction for the developed hanger device with saved number of punching the rolled steel panels.

Domestic construction industry has experienced many difficulties as it has been on a downward. It's a way that active modular structure market to solve this problem. However, as Modular structure technical standard in Korea is in the early stages, our modular factory maufactured rate is almost 40% lower than overseas. Besides, there is less design diversity so it just applies for a few buildings like low-rise building and general group barrackes. To deal with these problems, it is essential to modulating the equipment which can improve the production rate. This will help to ensure the quality, shortening of the construction period, the reduction of labor costs. We have defined the name of segmented by each installation location of the equipment to modulating equipment. And it was examined the suitability of the modulating of the location-specific utility system. The results of the analysis are discussed on the page.

Reduction of labor hour for cleaning up of the used abrasives after blasting. is attempted by improving the efficiency of abrasive recovery process in the protective coating of ship's block, For this purpose, the theoretical background for pneumatic transport technology in the abrasive recovery system as well as experimental evaluation on the effect of design parameters such as flow pattern, saltation velocity and pressure drop on the efficiency of the abrasive recovery system are employed . By optimizing the operating parameters such as the length and diameter of the suction hose, specification of recovery device and recovery mouth, a new method which can dramatically increase the efficiency of abrasive recovery system, is proposed.
