Since the late 2000s, there has been growing preparation in South Korea for a sudden reunification of South and North Korea. Particularly in the power industry field, thorough preparations for the construction of a power infrastructure after reunification are necessary. The first step is to estimate the peak load demand. In this paper, we suggest a new peak demand estimation methodology by integrating existing correlation analysis methods between economic indicators and power generation quantities with a power supply interruption model in consideration of power consumption patterns. Through this, the potential peak demand and actual peak demand of the Nation, which experiences power supply interruption can be estimated. For case studies on North Korea after reunification, the potential peak demand in 2015 was estimated at 5,189 MW, while the actual peak demand within the same year was recorded as 2,461 MW. The estimated potential peak demand can be utilized as an important factor when planning the construction of power system facilities in preparation for reunification.

The purpose of this study was to analyze the demand estimation erection of lifetime sports facilities for making an accurate estimate of its demand on the basis of the rate of the people participating in lifetime sports activities. Participation rate was determined on the basis of the fact-finding survey [by the Ministry of Culture and Tourism(2000)] as a basis research on facilities demand, and its demand was calculated by making an estimate of facilities demand. An estimate of facilities demand was made in the equation by participation population, facilities demand for each person, sports space area for each person, time of sports, cycle of sports, possible time to use of sports space. Facilities demand for each person by sports event is the following: $swimming;0.03m^2$, $basketball;0.045m^2$, martial arts(taekwondo, judo, korean fencing);0.003 $75m^2$, $aerobics;0.0289m^2,\;health;0.00326m^2,\;badminton;0.00323m^2,\;tennis;0.01429m^2,\;soccer;0.1112m^2,\;squash;0.01323m^2$.

현재 우리나라는 치과의사 전문의제도가 도입되고 저출산 고령화 사회로의 급속한 이행 등 여러 이유로 소아치과 전문의 수급에 관한 연구가 절실한 실정이다. 본 연구는 소아치과 전문의 수요추계에 적합한 모형을 모색할 목적으로 의료인력 수급에 관한 타 분야의 기존 연구들을 고찰하여 다음과 같은 결과를 얻었다. 1. 소아치과 전문의의 수요추계는 의료수요에 근거한 방법을 적용하는 것이 적절할 것으로 사료되었다. 2. 추계 모형에 필요한 독립변수로는 크게 유병율, 수진율, 의뢰율 출산율, 생산성, 연간 진료일수 등이 있었으나, 이러한 변수들에 대입하기 위한 기초자료가 부족한 것으로 나타나, 이를 보완할 설문조사와 전문가 의견조사가 필요할 것으로 판단되었다. 3. 독립변수는 각 특성에 적합한 회귀모형을 설정하여 추계하고, 가중치를 주어 추계 모형에 반영해야 할 것으로 판단되었다. 향후 추계 모형에 대입하기 위한 독립변수의 생성과 추계연구, 전문가의 검증과정이 추가로 필요하며 이를 토대로 소아치과 전문의 수요를 추계하여야 할 것으로 사료된다.

This study is performed the multinomial logistic regression with the officials needs level about a component of knowledge administration for drawing a demand estimation model in the knowledge administration activities. This study is not that an activity and domain of knowledge administration is to apply and to operate uniformly it in public sector, one is suggested an application with a demand diagnose of knowledge administration in order to saw a course of the knowledge administration programs to suit a function and role of public administration. A result of this study is that an activity and domain of the knowledge administration is different from a component of it namely, knowledge creating, knowledge organizing, knowledge sharing and distribution, knowledge utility, and knowledge store. And the officials individual characteristics, administration agency, a kind of business, and a function and role of work are different from demand of knowledge administration. Also, the practical use of KMS (knowledge management system) is not so high in public sector. Accordingly, the tools of knowledge administration will deliberate on a consolidation with the existing system in the device.

1. Comparison of demand and supply A. Assumption of estimation of demand and supply we will briefly assumptions used for presumption once more before comparing the result of estimation of demand and supply examined previously 1) supply - The average applying rate for state. examination of graduate: ${\alpha}$=1.03109 - The ratio of successful applicants of state examinations: ${\beta}$=0.97091 - Mortality classified by age : presumed data of the Bureau of statistics - Emigrating rate: 0 % - Time of retire: unconsidered - An army doctor number: unconsidered and regard number of employed oriental medicine doctor. - Standard of 1995 : The number of survival oriental medicine doctor is 8195. the number of employed oriental medicine doctor is 7419. 2) demand - derivated demand method Daily the average amount of medical treatment: according to medical insurance federation data. there is 16 or 6 non allowance patient, we consider amount of medical treatment as 22 persons in practical because 21.94 persons (founded practical examination) are converted to allowance in comming demand. Daily the proper amount of medical treatment: 7 hours form -35 persons 5 hours 30 minutes form -28 persons. Yearly medical treatment days: 229 days. 255 days. 269 days . Increasing rate of visiting hospital days: -1996 year. 1997 year. 1998 year- . Rate of applying insurance: yearly average 71.51% (among the investigated patient) B. Comparison of total sum result 1) supply (provision) Table Ⅳ-1 below shows the estimation of the oriental medicine doctor in the future.
