  • New cities and industrial complexes are being developed actively according to the government's policy. To determine the size of investment, number of power lines and substations for stable power supply to newly developed industrial complexes, the accurate estimation of power demand is necessary. "The standards for the estimation of power demands in newly developed residential and industrial complexes" established by KEPCO in 1991 have been used up to now. But the background for the estimation of power demands is weak and the accuracy has not been verified. Also, it has been passed above 10 years since their establishment and the social & economic situations have changed a lot, which requires an urgent revision. Through this survey and analysis of existing areas, new standards that will enable more accurate estimation of power demands in new cities and industrial complexes to be developed in the future are established by calculating the some kinds of power demand factors.

  • The objective of this study is to provide new direction on house design in consideration of the user's life pattern. To this end, pc usage status at home, demand for pc using space, and requirements for pc room interior were analyzed. A survey was taken by parents and the SPSS win.10 was applied for analysis. The survey was conducted for 2 months, starting May 2004 to see the computer usage at home, demand and satisfaction for the computer's room. The results of this study were as follows; The oldest son or daughter in a family was the main user of the computer, posting 71%. 42percent of respondents said they used the pc in their son's and daughter's room while 36% answered living room. It reflects that the whole family want to use the pc in their sharing room, or for their children's convenience. Currently, inconvenience of space-related constraints for using the pc was not that high, which possibly stems from a lack of awareness of inconvenience in using the pc. However, the need for furniture and space for refreshment was suggested. Through this study, it is expected that new housing designs need to be made to reflect these requirements into interior design and building plan for user's convenience.

  • 본 연구는 한국노동연구원의 사업체패널에 새롭게 포함된 스마트공장 관련 정보들을 활용하여 스마트공장이 노동수요에 미칠 영향을 추정했다. 스마트공장의 도입은 전반적으로 생산직의 업무량을 감소시키며, 스마트공장 수준이 고도화 될 수록 업무량 감소 정도는 더욱 커진다. 특히 동일제품을 반복 생산하는 공정에서 두드러진다. 반대로 스마트공장이 표방하는 지능화 및 연결성과 관련된 관리직, 기술전문직 등의 직종이나, 다양한 제품의 혼류 생산을 구현하는 과정의 생산직의 경우 업무량이 늘어나는 것이 관찰된다. 이는 기존 연구에서 제시한 결과와 전반적으로 부합한다. 본 연구의 의의는 최종 노동수요가 아닌 스마트공장이 표준적인 업무량에 직접적으로 미치는 영향을 추정했다는 데 있다.

  • 가구의 지속적인 승용차 보유 증가로 인한 승용차 이용 증대는 교통부문에서의 온실가스 감축 목표 달성에 큰 장애요인으로 작용하고 있다. 특히 가구의 승용차 통행수요는 가구원수, 가구소득, 거주지역 등 다양한 가구특성에 의해 결정되기 때문에 이러한 가구특성 변수들이 승용차 통행수요에 미치는 영향, 즉, 가구의 승용차 통행수요에 대한 탄력성 분석이 필요하다. 본 연구에서는 1995부터 2007년까지의 가계동향조사 자료를 활용하여 가상패널자료를 구축하고, 이 자료를 토대로 패널모형을 추정하여 가구의 승용차 통행수요에 대한 장 단기 가격 및 소득탄력성을 추정하였다. 실증분석결과, 승용차 통행수요의 단기 가격탄력성은 0.2974~0.4280, 장기 가격탄력성은 0.4087~0.6275로 분석되었고, 단기 소득탄력성은 0.3364~0.6281, 장기 소득탄력성은 0.7098로 분석되었다. 본 연구에서 도출된 승용차 통행수요에 대한 장 단기 가격 및 소득탄력성 추정결과는 향후 교통수요관리 정책의 효과를 분석하는 데 정량적 기초자료로서 활용될 수 있다고 판단된다.

  • This study aims to build a model dealing with the location decision of new manufacturing firms and their land demand. The model is composed with 1) the binary logit model structure identifying a future probability of manufacturing firms to locate in a city and their land demand; and 2) the land use suitability of the land demand. The model was empirically tested in the case of Anseong City. We used establishment-level data for the manufacturing industry from the Report on Mining and Manufacturing Survey. 48 industry groups were scrutinized to find the location probability in the city and their land demand via logit model with the dependent variables: number of employment, land capital, building capital, total products, and value-added for a new industry since 2001. It is forecasted that the future land areas (to 2025) for the manufacturing industries in the city are $5.94km^2$ and additional land demand for clustering the existing industries scattered over the city is $2.lkm^2$. Five industrial complex locations were identified through the land use suitability analysis.

  • 이 논문은 한국 노동시장의 수요구조에 관한 기존 연구들을 서베이한 것이다. 한국 노동수요의 특징을 보면 노동과 자본 간에 대체재 관계가 성립하며, 노동을 사무직과 생산직으로 세분해도 대체관계는 변함없다. 대체탄력성의 크기는 0과 1 사이에 있다. 고용과 근로시간은 대체/보완 관계가 명확하지 않다. 법정 근로시간 단축은 실 근로시간을 단축시켰으나 고용은 늘지 않았다. 노동수요 탄력성은 단기에 0.5 미만으로 작다. 기술변화는 1980년대 중반 이후 노동절약적으로 변하였고 1990년대 중반 이후 숙련편향적 성격으로 숙련노동 수요를 늘렸다.

  • The main purposes of this article are to introduce the theoretical backgrounds and empirical application methods of two different Models for the function of expenditure, and to compare the goodness-o(-fit of the two models: a single-equation model and a complete-system-of-demand-equation model. For the empirical analysis of the single-equation model, a linear formula and a double-leg formula were employed. In order to test the complete-system-of-demand-equation model empirically, the \"Linear Approximation/Almost Ideal Demand System (LA/AIDS)" was used. The independent variables were the total living expense and expenditure categories Price index. The data used in this study were obtained from the quarterly statistics of "The Annual Report on the Urban Family Income and Expenditure Survey (Dosigagyeyonbo)" and "The Annual Report on the Consumer Price Index (Sobijamulgajaryo)," for the years 1994 to 1997. The goodness-of-fit (R-square) was higher with the complete-system-of-demand-equation model than with the single-equation model for the budget share on food (excluding eating-out expenses) and for the share on cultural and recreational activities. However, there was no difference between the two models in terms of the proportion of the expenditure on automobile fuel.fuel.
