우리나라와 같이 가용 국토면적이 좁은 상황에서 도시의 급격한 외연적 팽창은 여러 도시 및 환경문제의 원인으로 작용할 가능성이 커진다. 도시 스프롤로 인하여 발생하는 도시문제를 파악하고 이에 대한 대책을 마련하기 위해서는 그 양상에 대한 정확한 측정이 선행되어야 한다. 본 연구의 목적은 면적, 분포, 형태 등 공간구조 관점에서 수도권 스프롤 양상의 시공간적 변화를 파악하는 것이다. 이를 위하여 경관 분석 툴인 FRAGSTATS을 이용하였다. 주된 연구 결과는 다음과 같다. 첫째, 1980년대 말 이래 수도권의 스프롤은 지속적으로 심화되고 있으며, 그 경향은 1990년대 보다 분명하였다. 1990대에는 비지적 개발이, 2000년대에는 충진 개발이 상대적으로 강하였다. 둘째, 권역별로 보면, 스프롤 경향과 개발의 방식이 권역별로 상이하게 나타났다. 경관지수 측면에서 과밀억제권역의 스프롤 경향이 가장 강하지만 충진 개발이 우세한 반면, 성장관리권역1의 경우 1990년대는 비지적 개발이, 2000년대에는 충진 개발이 우세하였다. 성장관리권역2의 경우 1980년대 이후 비지적 개발이, 자연보전권역의 경우 스프롤의 수준이 가장 약하지만 점차 그 경향이 강해지고 있다. 셋째, 수도권 스프롤 양상은 서울로부터의 거리와 방향에 따라 상이하였다. 1980년대 말에는 서울에 인접한 시군에서, 1990년대 말에는 서울 인접 시군과 남부지역에서, 2000년대 말에는 서울의 남부지역과 북부지역에서 스프롤 현상이 뚜렷하였다.

본 연구는 도시재생 관점에서 입체도시의 효과를 밝히고, 국내 입체도시계획 관련 제도의 문제점과 한계를 고찰함으로써 제도적 개선방안을 제시하고자 수행되었다. 그리하여 사례 분석을 통해 도시공간 연결, 지역경제 활성화, 기반시설 확충, 주택 공급 등 입체도시의 도시재생 기능과 역할을 파악하였으며, 제도적 문제점으로 국유재산에 대한 사권설정 금지로 민간참여가 저해되고, 2차원적 토지이용계획에 의거한 획일적인 기반시설 설치 기준으로 일정비율 이상의 토지 확보가 없으면 입체공간 활용이 어려우며, 법률간 연계성이 미흡한 문제를 도출하였다. 결론적으로 지역기반 산업구조 다양화 및 도시기능 강화 등을 목표로 입체시설 추진을 적극 지원 유도하고, 구도심 구역을 대상으로 입체 복합개발을 추진하며, 노후주택가의 공원, 학교, 도로, 전통시장의 하부공간을 활용한 보행로, 지하상가, 주차장 등의 도시재생사업 실현을 위해 중앙정부, 지자체, 민간부문 간 협력이 이루어져야 한다.

Many administrative policies for regional activation have progressed the expansion and improvement of convenience institutions. Most appraisals about rural community influenced by urban life convenience are affirmative, but chasing urban life convenience is a cause of breaking out regional identity. Recently, new rising methods of theme and characteristic to imply regional identity, are ways of regional activation through neighboring network around satellite of rural community. In this study, I research and suggest applicable possible proposal of rural communities in Korea. by survey of neighboring network methods of Asan Live Museum in Japan applied ecomuseum concept for regional activation.

As the hydrologic cycle is transformed by the expansion of impermeable area as a result of the urbanization, the function of an ecosystem is deteriorated by the transformed hydrologic cycle. In this study, a SWMM code was modified to have a groundwater pumping option about rivers-aquifer interaction to be possible. The modified SWMM was applied to continuous simulations of urban runoff from Hakuicheon watershed and it was used to analyse the effect of a groundwater pumping. The modified SWMM overcame the limitation of the ground subroutine that it only simulate groundwater inflow from ground to rivers. The result of continuous simulation of groundwater pumping is that surface runoff, groundwater runoff and groundwater level are well simulated, and Modified SWMM expressed groundwater runoff by negative number (-) when groundwater level is less than river stage.

In order to improve the traffic enviroments in the urban streets of Seoul, the computer controlled traffic signal system was installed on 45 intersections at 1980. Afterward, yearly expansion was done to the numbers of 132 intersections and 232 loop detectors. The problems of timing plans were discussed, mainly pedestrian crossing timing as well as the generations of split and offset. The broad urban streets more than 30m require long phasing time of pedestrians, even though the equivalent or correspondent traffic volume is rare. The configuration of computer system for traffic control was disscussed in terms of control strategy. An overview also given. The improvements were measured at every quater. The travel speed improved to 42%, delay time reduced to 41% and number of stops to 43% respectively.

The full extent of damage depend greatly on the quick and rational decision making by the incident commander soon after the disaster. The decision that everybody should wait by the captain, not to enter into the ship by the first dispatched incident commander, broadcasting failure have brought about a huge loss of life at Sewol cruise ship incident. Thus this study reviews the training and education system supporting the rational crisis decision making performed by the incident commander to cut off the expansion of disaster which is caused by the failure of the incident situation awareness and the decision making described above.

The expansion of demand associated with leisure, which has resulted from the elevated standard of living, has made the domestic tourist demand diversified. Recently, people, especially urban population, show the higher interest and need for environmentally friendly rural tourism. This study aims to grasp the utilization of recreation roles of tourist farms and then to evaluate the economic value for recreation roles of tourist farm using Traveling Cost Method. Data were collected from a survey in 2003. The results show that its value is 62,037 won per head annually and so the tourist farms play their role of connecting the urban population with rural amenity.

Recently, with expansion and advent of the wire&wireless networks has been set up by various heterogeneous networks in urban transit networks. It's focussing on an interworking technology. As same as way, In a subway & railway monitoring system networks has been set up by various heterogeneous technologies such as IEEE802.11 WLAN, IEEE802.15 WPAN, DVBT, UWB, BinaryCDMA, ZigBee. These heterogeneous technologies is deeply investigating for the purpose of interworking and easy control as a research area. In this paper, we propose using VoiceXML based of XML for ensure interworking within heterogeneous subway & railway networks. Therefore It will be provide service for staff who has moving and anywhere, anytime in outside. Eventually, we expect that confirm efficiency of effective system through this study.

Many people think, in common that An expansion toward outer city is a development, and it can be a general trends in a new development in a growing city. But We can see many case which moving of a public building are considerate as a core element to promote the new development towards outer city, and that is a negative element of slum in central area and community making. There are many aspects to pursue sustainable urban structure of in a city, and public building is a very important element to manage deteriorate central area from social slum in a old town. In this presentation, three project, Local Authority office of Chonnam province, Kwangju Station, and Hyper Urbanity, and it shows sustainable concept of the public building as a core in a city development. The effect of the projects are expected sustainable development and community in terms of social, cultural and historical aspects.

The deterioration rate of concrete structures in urban area is accelerated due to rapid urbanization and environmental pollution. Repair materials and methods newly introduced in Korea should be investigated whether they are appropriate for the urban environment in Korea. The creek concrete structures are exposed in severe environmental condition than others. Based on these background in mind, the study is focused on evaluation of performance on repair materials used to rehabilitate creek concrete structures. To evaluate the performance of repair materials, four kinds of repair materials were selected based on polymer emulsion. This experimental study was conducted on fundamental performance such as setting time, compressive strength, bending strength, bonding strength, thermal expansion coefficient, and durability performance such as chloride diffusion, carbonation, chemical attack, and steel corrosion rate. On the basis of this study, the optimal repair material which is proper to the environment condition can be selected and service life of creek concrete structures can be extended. As a result, the life cycle cost can be reduced and the waste of material resources will be cut down.
