도시의 외연적 확산은 도시 주변부의 농지나 녹지지역을 도시적 용도로 전환시킨다. 도시주변부의 개발은 도시기반시설의 설치비용 및 교통비용 등 여러 가지 사회적 비용을 수반한다. 도시의 확산과정에서 새롭게 개발되는 도시 주변부의 개발특징을 파악하고 이를 합리적으로 관리하는 것은 지속가능한 도시발전을 위한 중요한 과제이다. 본 연구는 대구광역시를 대상으로 1990년과 2000년 사이 도시주변부의 신개발지를 대상으로 위성영상, 토지관리정보시스템, 인구 및 주택총조사 자료 등을 GIS로 구축 활용하여 토지이용전환에 영향을 주는 요인, 토지이용현황 및 공간적 분포, 개발 밀도 등을 중심으로 개발특성을 도출하였다. 분석결과 대구광역시의 도시지역의 확장은 주거지 개발이 주도한 가운데 지역에 따라 산업단지 및 유통단지 등의 형태로 토지이용의 차이를 보였다. 이러한 결과를 기초로 도시개발의 입지, 규모, 밀도 등의 도시성장관리에 필수적인 다양하고 유용한 정보를 제공할 수 있었다.

Polymer electrolyte fuel cells(PEFC) have been considered to be a suitable candidate for residential, portable and mobile applications, due to their high efficiency and power density, even at low operating temperature. KIER developed a 5kW class PEFC system for residential application and operated the system for over 1,000 hours. To develop a 5kW PEFC system, performance of a cell was improved through successive tests of single cell of small and large area. Fabrication of three 2,5 kW class stacks, design and fabrication of natural gas reformer, design of auxiliary equipments such as DC/DC converter, DC/AC inverter and humidifying units were carried out along with integration of components, operation and evaluation of total system. During the development period from 1999 to 2001, MEA(membrane electrode assembly) fabrication technologies, design and fabrication technologies for separators, stacking technologies and so on were developed, thereby providing basis for developing stacks of higher efficiency and power density in the future. Experience of development of natural gas reformer opened possibilities to use various kinds of fuels. Main results obtained from the development of a 5kW class PEFC system for residential application are summarized.

Proton Exchange Membrane Fuel Cell (PEMFC) is an attractive candidate for residential power generator due to fast start-up and stop, high efficiency, low emission, and high power density. In this study, we employ short module stack to understand the performance of the unit cell of the stack in terms of operating temperatures. To simulate the practical fuel cell stack of residential power generator, the structure and active area of the short module stack is kept the same as that of the practical fuel cell. The results shows that the electric potential of short module stack is different from the number of cells times the potential of unit cell because of cell-to-cell variation.

In the modern city in which the high-density and complex land use is needed, high-rise residential-commercial buildings appeared as a scheme to arrange a metropolitan residence with multiple high-techs and to induce activation of the city with leading the settled population to flow into the city. And the need of the times is to actively apply the eco-friendly notion to the architecture. In this study, the works of Ken Yeang who is regarded as an eco-friendly architect to make high-rise residential-commercial buildings ecological should be focused on with analyses of eco-friendly characteristics in inside, intersection between inside and outside, and outside of his works. The result o the study would be the suggestion to design eco-friendly high-rise buildings which make the city rise in quality.

This study is about occurrence pattern of vacant spaces as a urban decline indicator to consider a decline of old hillside residential area from spatial structure perspective. For investigation based upon vacant space and the street structure, this study selects Ami Chojang-dong in Seo-gu, Busan, of which 79.7% of total area is over a gradient of $10^{\circ}$. Focused on relationship between occurrence pattern of vacant spaces and 'vertical alleys(link)' serving as main movement path of local residents in hillside residential area, the length, numbers, slopes, and use characteristic of vertical alleys were analyzed using Arc GIS 9.3 program to classify characteristic zone types of spacial structure in hillside residential area. After the occurrence pattern of vacant space are interpreted in relation with building density, vertical alleys' number length slope, the social and economic issues have been considered as well. After analyzing the occurrence pattern of vacant space, this study argues that the occurrence pattern of vacant space in old hillside residential area is rather affected by street structure system consisting of vertical alleys than the impacts of social economical issues.

To accomodate increasing housing shortage in many cities, Korean Government has implemented various residental land development projects to provide more land for new housing construction. Most of the residential areas developed by these projects were used for multi-family housing units. Under this process, the size and location of the neighborhood service facilities in the development area were regulated by uniform standards. For this reason, the neighborhood service facilities were not able to be provided according to the household density but provided in minimum status required by these standards. Based on these considerations, this study aimed to evaluated residential land development project conducted by pubilc authority, one of the residential land development projects in Korea. Results of the case studies confirmed findings from literature review and proposed that existing regulations applied to these projects need to be amended not only to accomodata unique situation of each development area but also to enhance level of the dwelling environment. As ways to resolve these problems, this study suggests followings: (1) more flexible operation of the regulations, (2) inclusion of the socio-economic characteristics of the perspective resident in planning process, and (3) introduction of design techniques in the project. Finally, this study proposed future study directions in relation to this issue.

본 연구에서는 두루미류의 개체군 및 서식밀도에 영향을 주는 요인 중 자연적 요인과 함께, 인간에 의한 직 간접적인 교란의 영향에 의한 서식분포모델을 도출하고자 하였다. 대상지역은 강원도 철원군의 민간인통제지역이며, 2009년부터 2014년까지 매년 1월의 두루미와 재두루미의 분포를 대상으로 하였다. 두루미류의 서식밀도는 거주지, 군사시설, 통행량이 빈번한 도로와 가까울수록 서식밀도가 감소하였고, 거리가 멀어질수록 서식밀도는 증가하였다. 통행량이 적은 도로, 잠자리와의 거리 및 비닐하우스의 밀도가 증가할수록 두루미류의 서식밀도는 감소하는 경향을 보였다. 또한, 두루미류의 서식밀도는 민간인통제지역 외부보다 내부의 밀도가 높게 나타났다. 전체 요인을 이용해 단계적 진입을 통한 회귀분석의 결과, 두루미는 $3.4{\times}$AV_FE (이용이 가능한 농경지의 면적 ha)+$1.27{\times}$N_RES (거주지와의 거리 km)-$0.54{\times}$CCZ_0 (민통선 내:0-외:1)+$0.4{\times}$N_HTR (통행량이 많은 도로와의 거리)-1.40이었다. 재두루미는 $9.0{\times}$AV_FE-$5.47{\times}$N_LTR (통행량이 낮은 도로와의 거리 km)+$0.49{\times}$N_Lake (저수지와의 거리 km)+1.02이었다. 두루미와 재두루미 모두 공통적으로 이용 가능한 농경지의 면적이 중요하였고, 두루미에서는 거주지와의 거리 및 통행량이 많은 도로와의 거리가, 재두루미에서는 통행량이 낮은 도로와의 거리가 중요한 요인으로 나타났다. 두 가지 종 모두에서 모델에 의한 추정값과 실제 분포를 이용한 밀도 사이에 유의미한 상관관계가 나타났다.

The purpose of this study is to identify the characteristics of young farmers' residential location characteristics. Based on residential location theory and previous studies on the stated preference for residential environment of young farmers, this study develops a spatial econometrics model using housing and neighborhood variables, accessibility variables, natural environment variables and farm economics and management variables. The findings suggest that the higher rate of young farmers has a positive relationship with higher population density, higher housing price, closer distance to city centers and Eup districts compared to Myeon districts. In addition, areas which have higher rate of farmers with high sales and growing certain crops such as fruits and vegetables are revealed to have higher rate of young farmers. This study presents that maintaining rural vitality is also crucial for attracting young farmers to rural areas and remaining them in the farm as active agricultural workforce.

Since the middle of 1990, "High Rise Residential Complex" has been started to construct to fulfill the use of high density land use. In addition, it bacame a major solution for a rehabilitation project to achieve a high volume ratio, which in turn brings a good business. In this study, POE is applied to secure residential satisfaction level between Apartment and High Rise Residential complex. Also life style differences are investigated between the two type of complexes. It was resulted that recent High Rise Residential Complex is quite acceptable in most respects, however interior vetillation and direct wind flow from living space through dining - kitchen to ease the cooking scent is not a satisfactory level. These two factors are most highly demanded for future design of High Rise Complex in considering specialties in our cultural life style.
