This paper is aimed at embodying the optimal system for foreign workforce supply of nation in order to introduce qualified foreign workers at the age of eleven thousand foreigners. It is difficult to employ foreign workers qualified and it makes job rosters' confidence fall down which is the supplementary resources when selecting due to the insufficient job seekers' detailed information. Therefore, the moving control system should be added in current system to deal with these problems. For this, in this paper, we propose that the moving picture embedded system applies to the current EPS utilizing multimedia, network and database technologies as regards adding the function of the moving picture synthesis to recent system. It also suggests the advanced foreign employment control system related to the advanced system which makes employers to hire foreign workers satisfying their requirements and demand.

In the construction project, construction supervisor influences greatly the construction managements such as process management, quality management, safety management, and cost management. Therefore, from the first stage of the project, the managing activities of the supervisor are consistently needed. But the assesment of supervisor's work and cost has not been made enough in the public construction project. And there have been doubts as to whether a supervisor can take a consistent managing activity from the early stage of the project. Accordingly, the works between Korean supervisor and foreign supervisor in their public corporations are analyzed and compared in this paper. And the evaluation is made each of the cost for supervisor and the cost for engineer as a substitute of supervisor in construction project. This study is believed to contribute to improving the supervisor's work and reducing the personnel expenses and construction indirect cost.

This study estimated indirect economic benefits of the introduction of Korean Spatial Information System. Korean academic society has been reluctant to consider indirect benefits as an item of benefits in cost-benefit analysis. Nevertheless, other countries including England recommend to consider some indirect benefits like option value as an important item of cost-benefit analysis, especially in the case of transportation projects. This study estimated indirect benefits of the introduction of Korean Spatial Information System using Contingent Valuation Methods: Indirect benefits of the project are so significant in terms of statistics and substantial in terms of magnitude that decision making can differ from the case without consideration of such indirect benefits.

CAD/CAM 시스템의 중요성에 대해서 많은 사람들이 인식하고 있으나, CAD/CAM 시스템의 장비 가격이 비싸고,시스템을 작동시키기 위해 전문인력도 필요하다. 대부분의 CAD/CAM 시스템에서 컴퓨터로는 Workstation을 이용하는 경우가 많아서 CAD/CAM 시스템의 유지 보수에많은 비용을 지출하여야하므로 중소업체에서는 시스템의 도입이 어려운 실정이다. 또한 CAD/CAM 시스템이 주로 외국에서 개발되었기에 모든 작동 명령어나 메시지도 외국어를 사용하고있다. 따라서 외국에서 개발된 CAD/CAM 시스템에 익숙해지는 데는 시간이 걸리며 자신이 사용하는 기능외에 다른 기능을 사용하지 않는 경우가 많다. 본 연구에서는 위의 문제점들을 다소나마 해결하기 위하여 다음과 같이 1) 저렴한 장비비 및 유지비를 위하여 IBM PC 호환기종을 사용하였으며, 2) 사용의 편리성을 위해서 사용자와의 대화에 있어한글과 그래픽을 이용하였고, 3) NC 코드의 생성에 있어 NC 기계에서 제공되는 기능들을 활용하여 NC 코드의 길이를 최소화 하였으며 4) 형상 입력, NC 코드 Download 등이 한 프로그렘에서 이루어 지도록 하였다.

본 논문의 목적은 첫째, 자본자유화로 인해 통화공급 구조가 이미 균형에서 이탈하여 심각한 수준의 불균형 상해에 있다는 점을 실증적으로 입증하고자 한다. 둘째, 자본유입에 따른 정책조정 비용을 감안한 통화정책 모형을 통해 주장에 대한 이론적 근거를 제시하고, 정책 조절에 수반되는 손실비용(損失費用)과 Mundell의 $\ulcorner$할당 문제(割當 問題)$\lrcorner$를 다시 조명해 보고자 한다. 세째, 자본유입에 따르는 문제점들을 해결할 수 있는 정책방안들을 Modigliani ar Miller의 명제(命題)에 입각한 새로운 각도에서 합리적 인 증시정책을 모색해 보고자 한다. 분석의 이론적 틀로서는 자본유입에 따라 수반되는 불확실성하의 정책조절 비용을 감안한 손실비용 최소화(loss cost minimization)를 통해, 통화 당국자는 총통화량을 정책적으로 내정된 목표값에 수렴시킨다고 가정하였다. 다른 한편, 자본유입에 따르는 문제점들을 통화시장에만 제한시키는 부분적(部分的) 균형분석(均衡分析) 대신, 이를 증권시장으로 직접 연계시켜 두 시장으로 확장된 틀을 활용하였다. 본 논문의 연구방법은 다음 두가지 측면의 접근식을 따랐다. 첫째, 자본자유화정책의 특성을 살펴보기 위해, 자본자유화 시점을 기준으로 삼아 과거 자본통제 시대의 $\ulcorner$사후적(事後的)인 중화정책(中和政策)$\lrcorner$에 의존하는 $\ulcorner$소극적(消極的)인 증권정책(證券政策)$\lrcorner$과 자본자유화시대의 $\ulcorner$사전적(事前的)인 상살정책(相殺政策)$\lrcorner$에 의한 $\ulcorner$거시적(巨視的)인 증권정책(證券政策)$\lrcorner$을 통해 고찰하는 비교분석론에 입각한 접근식을 택했다. 둘째, 외국자본의 유입동기(流入動機)를 문제해결의 시발점으로 삼아 이를 새로운 개방정책과 직결시켜 문제해결의 실마리를 풀어 보려는 선험적(先驗的) 접근식(接近式)을 택했다.

A multi-regression model was developed to estimate the decommissioning cost for Kori unit 1 using foreign nuclear power plant (NPP) decommissioning cost data. First, the decommissioning cost data were collected for 13 boiling water reactors and 16 pressurized water reactors and converted into the values as of November 2019. Then, for the regression model, the decommissioning cost was chosen as the dependent variable, and two variables were selected as independent variables: a contamination factor that was designed to reflect the operational characteristics of the decommissioned NPP and the decommissioning period. A statistical package in the R language was used to derive the regression model. Finally, the regression model was applied to estimate the decommissioning cost for Kori unit 1. The estimated decommissioning cost for Kori unit 1 was 663.40~928.32 million US dollars (782,812~1,095,418 million Korean won).

Analyzing the effects of information technology(IT) in the life insurance Industry is important in establishing the direction for future information technology investment. In this research, the cost-elasticity of IT capital stock was measured by the SUR technique, using the second-order translog cost function, which was drawn out by a Taylor expansion of the multi-product joint cost function. Analysis was made based on data from 1991 to 2003 collected from 33 life insurance firms. The results show that although the effects of information technology investment vary according to individual life insurance firms, half of the life insurance firms surveyed reduced their costs by investing in information technology. The research also revealed that although large life insurance firms reduced their costs by investing in information technology medium & small life insurance firms and foreign ,life insurance firms increase their costs. Additionally, although both information capital and information labor increase as the information budget increases, the increase in information capital is larger than one in information labor. Because the price of information capital is decreased rapidly more than one of information-related labor.

The construction industry is a labor-oriented and quality, cost, and schedule performance is effected by technicians. However, the construction industry have faced a labor shortage problem. Therefore, technician graying and no new workers inflow cause labor shortage and decline of worker's skill level. The utilization of foreign technicians instead of domestic technicians has been increased in the construction industry. This paper performed questionnaire survey for 43 managers on 14 project fields to determine the current status and problems of construction technicians and to propose a improvement plan. As a result, most foreign technicians are carpenters and iron workers, but the skill levels are generally lower than domestics. The major problems for foreign technicians are communication and non-skilled. Then, labor productivity and accident rates of foreign technicians are higher than domestics. This paper proposes that skill training programs, language lessons, and multi-cultural programs are effective to improve foreign workers' problems.

This study examines motivations for international students to study abroad at Korean universities. Employing qualitative and mixed methods, this study used grounded theory to analyse data obtained from student interviews, essays, digital storytelling videos, and student video representations to explicate the nature of study of six subjects. All subjects were enrolled in English Education courses during years 2014-2017. The researcher was the course instructor. Results from this study revealed that major codes that emerged from data analyses were those of economics, culture, language study, and personal development, corroborating with findings of most research literature regarding international students' motivations (OUSO, 2015). However, survey of professional literature and study data showed that motivational codes presented in the literature and this study, were discursive in nature in that each code was not only connected to all other codes, but also mutually co-constructive. As such, this study suggests that motivational codes found in study abroad literature were discursive in nature, resembling Bourdieu's (1991) theory of economic, social, and cultural capitals. Results of this study suggest that various motivations for studying abroad are subsumed under economic logic of expense and career development.
