The employment permit system for foreigners, which stresses introduction of foreign work force in a legal manner rather than in the position of being trainees, is anticipated to efficiently improve introduction and the overall management system of foreign work force and related difficulties such as illegal alien problems, absurdity on sending laborers overseas. In this paper, a prospective model of supply and demand of work force has been developed basing on various categories of industries and patterns about nationally practical foreign employees to look over efficient supply and demand of work force suiting employment of foreigner among foreign work force policies. To propose the prospective model, we have derived industry- and pattern-related matrixes of foreign laborers basing on Inter-Industry Analysis Method put forth by Professor Leontiyef in 1930, and through the derived matrix assessed repercussions concerning overall domestic industries and foreigner types and decided yearly weight; the capacity of supply and demand of foreign laborers can be compared through proposed statistical estimation and government estimation by combining the determined weight with yearly incomes of foreign laborers. This paper has thoroughly considered the particularity of our employment permit system for foreigners and applied the Weibull distribution and incorporated the dependence of foreign laborers during the limited period of 3 years to the industry relation analysis, ultimately proposing an efficient supply and demand method about domestic foreign work force.

Mothers with cerebral palsy children have much stress that is related to the care of children with cerebral palsy and to other household duties, and this state of the mother has an effect on the cerebral palsy child and on other household member. Mothers in such stressful situations use various coping patterns. The purpose of this study was as follows : to develop instruments that can be used for measuring the stress and coping patterns of mothers with cerebral palsy children, and to test a hypothetical model on the relationship between the mother's stress, her coping patterns and the variable affecting the stress and coping patterns. The results of this study can be summarized as follows : 1. The stress scale was composed of 44 items and Cronbach's ${\alpha}$ was .94, and the coping pattern scale was composed of 19 items and Cronbach's ${\alpha}$ was .80. The mean score of stress scale was 136.12 out of a total of 220, and the mean score of the coping scale was 72.87 in a total of 95. 2. In test of the hypothetical model, it was found that extra-care demand, the support of the husband, the degree of handicap, health status and self-esteem had statistically significant influence on the mother's stress(r=.285, -.262, -.133, -.126). And the support of the husband, formal support, informal support, and economic status were found to have statitically significant influence on the mother's coping patterns(r=.412, .178, .178, .138).

나전도안은 작품을 완성하는 데 필요한 모든 공정이 들어있는 것으로 기물의 종류와 형태, 크기, 장석과 나전 문양에 대한 내용이 포함되어 있다. 또 일부는 제작시기와 제작자를 비롯하여 작품 제작을 주문한 수요자에 대한 정보가 남아 있다. 본고에서는 송방웅(중요무형문화재 제10호 나전장) 소장 나전도안 도안 1,700여 점을 중심으로 일제강점기부터 현재에 이르는 기간 동안 시대별로 유행했던 문양과 기물, 그리고 수요자와 수급형태에 대해 알아보고자 한다. 도안의 대표적인 문양으로는 화조, 사군자, 문화재, 풍속인물, 수복자, 산수 등이 있다. 문양도안은 시대에 따라 변화하는데 근대를 대표하는 일제강점기에는 일본에 의해 작품제작과 수급이 통제되었던 배경과 맞물려 일본의 취향을 따른 문양 도안이 많다. 수요층도 일본인을 중심으로 일본과 친분이 있는 계층이 주를 이루었던 것으로 보인다. 도안의 중요성에 대한 인식도 시대적인 정황과 관계된 것으로 보이는데, 송주안이 일본에 거주하였던 시기와 남아있는 도안 중 가장 이른 것의 시대가 일치하는 것으로 보아 일찍이 공예 도안연구가 활성화되었던 일본의 영향을 받았던 것으로 추정된다. 그러나 일본과는 소재, 제작방식, 수급체제가 달랐던 만큼 일본과 한국의 도안에는 큰 차이가 있다. 해방 이후 현대로 접어든 1950년대에는 6.25 전쟁 이후 미군이 새로운 수요층으로 출현하여 이들이 선호하였던 소품을 장식하기 위한 한국적인 문양도안이 주를 이루게 된다. 1960년대 후반부터 1970년대까지는 외국산 자개가 수입되고 사용량이 증가하면서 도안의 크기와 내용, 종류가 다양해지며 조각법, 부식법 등의 새로운 기법도 등장하게 된다. 1970년대에는 경제성장과 맞물려 나전공예품에 대한 관심과 인기가 높았기 때문에 수요층이 다양하였다. 나전공예품은 전적으로 주문에 의해 생산되었는데, 수요층은 각종 단체와 가구 중개상, 그리고 개인으로 분류된다. 이 시기의 수요층 가운데 주목되는 것은 도안에 '부산 좌천동'과 '점촌'으로 표기된 가구 중개상과 개인 수요자인 '진범모친'이다. 부산 좌천동은 1970년대 자개골목으로 유명했던 곳으로 이곳의 상인들은 통영으로부터 다양한 종류의 나전공예품을 납품받아 재판매하였으며, 점촌은 문경의 탄광촌으로 이곳의 "김씨"가 광부들을 상대하던 접대부를 상대로 통영에서 만들어진 나전공예품을 조달하였다. 진범모친은 나전공예품을 소유하기 위해 개인들이 모여 만든 계의 대표로서 부산 대신동에 살았으며 통영에 삼층장을 비롯한 각종 나전공예품을 주문하였다. 1980년대에는 아파트 문화의 정착으로 붙박이장과 거실장, 주방기구, 소파 등 새로운 양식의 가구가 사용되면서 자개장의 입지가 크게 좁아졌다. 한때 통영에서는 끊음질이 크게 유행하여 나전공예품 제작이 활성화되는 듯하였으나 1980년대 말 이후, 사회 전반적으로 나전공예에 대한 선호도가 떨어져 수요자가 감소하였고, 이에 따라 나전 작품의 제작도 자연스럽게 줄어들게 되었다. 현재는 몇몇 장인들에 의해 명맥만이 유지되고 있다.

As the interests in eco-friendly energy has increased, the interests in Electric Vehicles(EVs) are increasing as well. Moreover, due to the government's economic support for EVs, penetration level of it has rapidly increased. These sharp increases, however, induce various problems in distribution system, such as voltage/frequency variations, peak demand increasement, demand control, etc. To minimize these possible matters, lots of research have conducted. Nevertheless, most of it assumed extremely important factors, such as numbers and charging patterns of EVs. It inevitably results in errors in their research, and thus make it difficult to prevent the possible matters from EVs. In this paper, therefore, we use actual EVs charging data from KEPCO, and analysis and deduction of it were conducted. The simulations were carried out for four aspect(season, region, purpose).

A system called demand response programs (DRP) is being introduced among various countries owing to the lack of new generation capacity and the higher fuel generation cost. It is a program which provides for the end-users to select their consumption of electricity by recognizing the value of their consumption in real time. That is, Demand Response can be defined as the changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity or other signals. It is expected that the effects of DRP are preventing price spike, improving supply reliability and social welfare and increasing option of customers. Considering the customer's thermal comfort zone, this paper determines the most profitable combination of optimal incentives and amounts of load reduction for a retailer to maximize profits according to predicted outdoor temperatures while implementing DRP.

The demand for coverall-type protective clothing are increasing in many industrial fields; however, it is impossible to evaluate the wearers' apparel fit because there is no commercialized pattern in the market. This study produces a manual for the process of acquiring patterns by separating PPE products into pieces to provide information on acquiring patterns. The analysis was on coverall-type non woven protective clothing in the domestic market, and 4 panels examined the validity, reliability, and efficiency of various possible methods on each step of process. Five steps were conducted to acquire patterns removing wrinkles, marking seams lines, separating seams, and pattern completing. The process of converting these into pattern files was designed through three procedures of digitizing, editing, and exporting and detailed stages. Fitting tests were undertaken, real patterns by actual modeling and pattern files by virtual modeling; all showed similar forms with outfits wearing ready-made protective coveralls. This study sought the most efficient and objective method of virtual modeling and proposed it as a manual. It is expected for the pattern reverse-designing manual through products analysis presented in this study that would be a helpful addition of information to the pattern tracing of pattern-less clothing products.
