Recently, expected casuality or property damage, such as flood damage, environmental destruction, etc, is increased because of the local heavy rain or flood by climatic changes. Especially, there are lots of property damages caused by increase of flood frequency and expansion of flood area because impervious rate is increased by urban sprawling development. Therefore, this research intends to analyze reasons of flood damage by each form and suggest protective measures through the typology of flood area for Haeundae-gu, Suyoung-gu, Saha-gu in Busan Metropolitan City with Busan's inundation trace map which has made from 2009. To achieve them, flood area was divided into water flooding type, river flooding type and seawater flooding type. And, protective measures focusing on previous prevention gave the relationship by dividing into managing system aspect, infrastructure building aspect and system aspect, so it approached flooding problems more objectively and scientifically. And, this research intends to suggest vitalizing measures for the utilization of inundation trace map in the future.

Modern urban cities are experiencing various problems like chronic traffic congestion, environmental pollution, reduced open space, shortage of affordable housing, deterioration of old downtown and sprawl. Under these circumstances, the urban sustainability can be grasped in many view points. Among these view points, urban growth management is one of the most recent and important issues that should be implemented by local government for the urban sustainability. This study will investigate the concept of Smart Growth as an executable strategy for the realization of sustainable urban growth management. On the other hand, one of the most important problems that hinder the urban sustainability is the lack of consistency in driving the sustainable strategy originated from the fragility of virtuous cycle of internal organizations themselves. This study will suggest an alternative local government organization model that enables the consistency and virtuous cycle of sustainable urban growth management based upon Regional Innovation System concept.

IT technologies applied in the urban places are being promoted in each area. Especially infrastructure is performed in the central role of technical support in urban area. However, u-City infrastructure has lack of integrated way and concentrated on only feasible technology which cause frequent substitution and the nested technology in urban area. Therefore this study sheds light on infrastructure through a overall considerations of urban compositional elements and interactions, and apply technology in the process of the industrial era, the domestic supply of urban infrastructure and the cycle comparison-analysis deal with the domestic implications when applied. The results of the study, first, the u-City infrastructure should be supplied by public. Second, u-City infrastructure is in need of the agile character, and standardization of the subtleties is needed. Third, a new system of integrated-macroscopic perspective should be established by changes that influenced by convergences of IT technologies and infrastructures. Fourth, u-City infrastructures planning should consider interactions of services, devices and systems.

Basically a land parcel consists of a land parcel number, land category, land boundary and area, and land value is mostly determined by the land category. Generally people want to change their land use to increase their land value so that they can expect more benefits from the land. However, changing land use causes several problems with land properties, haphazard urban expansions and land category non-coincidences. Unfortunately, no effective solutions exist for land category non-coincidence problems. In this study, we proposed a methodology that can classify the land category based land covers using high resolution satellite images and digital topographic maps. For this, we obtained a parcel based land use/cover classification map. Using both this classification map and a digital cadastral map, we inspected land category non-coincidences. As a result, land category non-coincidence rates could be statistically measured and interpreted and demonstrate a possibility that we could quantitatively interpretate and measure cadastral non-coincidence automatically.

Cheju Island is the most attractive resort area in Korea for its exotic landscape, natural beauty, and traditional culture which is quite different from that of the mainland. Until now, most of the recreational facilities and accomodations have been constructed along the coastal areas. Recently, mid-mountain area has been under very heavy development pressure because it is suitable for new sites for tourism facilities and the land price in the coastal area is very high. The mid-mountain area is the land located 200-600m above the sea level. It is a major source of water supply for the island and has exotic scenic beauty, which cannot be found in mainland but it is the area very vulnerable to water pollution Therefore, it is very important to manage this area based on the concept of environmentally sound and sustainable development in order to meet ever increasing demand for the land development The purposes of this project are: 1) to establish Geographic Information System for the whole island, 2)to formulate environmentally sound landuse plat However, There has been accuracy of the original map, defining criteria of analysis, updating of the data were identified for future tasks to be studied.

2010년 12월 8일 국회 본회의에서 "친수구역 활용에 관한 특별법"(이하 친수법)이 통과되었다. 친수법은 국가하천의 양안 2km 이내의 지역을 엄격한 기준에 의해 친수구역으로 지정하여 체계적으로 개발하도록 제도화하였다. 또한 특히 사업시행자를 공기업 및 지방자치단체 등 공공기관으로 제한하고 개발이익도 하천정비에 재투입하여 개발이익이 사유화되거나 이윤추구의 장이 되지 않도록 하는 법적 토대를 마련하고 있다. 우리나라의 하천은 지난 수십 년간 개발일변도 정책으로 하천 본래의 모습을 찾기 어렵다. 인구의 도시집중, 지속적인 개발, 하천에 대한 기대치 증가 등으로 앞으로도 하천 자체의 자정능력에 의한 회복은 기대하기가 쉽지 않다. 4대강 살리기 사업(이하 4대강사업)은 국내 하천의 이러한 절실한 현실이 고려되었다고 한다. 그런데 4대강사업으로 조성되는 수변지역을 그대로 방치하면 무분별한 난개발과 토지투기의 장으로 전락할 가능성이 크다. 또한 수변구역 주변의 넓은 토지는 이미 농경지화되어 있어 비료, 제초제 등 비점오염원의 하천유입으로 수질을 지속적으로 위협하고 있다. 이러한 제반 여건들이 친수법 제정의 주요한 동기가 되었다고 한다. 그러나 친수법의 제정에는 수많은 우여곡절이 포함되어 있다. 친수법은 법안이 발의된 이래 법안의 취지를 둘러싸고 향후 법 실행과 관련된 논의가 첨예하게 대립하여왔다. 본 연구는 이미 제기된 특별법의 문제점에 대하여 법적인 관점에서 짚어보고, 그에 따른 개선방안을 모색해 보고자 한다. 친수법의 제정을 위하여 꼭 특별법이라는 입법과정을 거쳐야 했는지 그리고 친수법이 상정하고 있는 사업의 성격 및 내용에 대한 법적인 타당성을 살펴보고자 한다. 또한 친수법 제4장에서 규정하고 있는 하천관리기금을 법률 구성의 입장에서 어떻게 파악할 수 있는지에 관한 점도 고찰하였다. 즉, 친수법이 구상하고 있는 [특별법의 제정${\rightarrow}$친수구역 개발에 의한 수익 창출${\rightarrow}$하천기금의 조성${\rightarrow}$건전한 하천관리]의 구도가 법적으로 어느 정도 균형과 조화를 이룰 수 있는지 고찰하였다.

Ulaanbaatar city, the capital of Mongolia and the center of Mongolian economy, increasingly needs to have a long-term urban planning and a system to impose a tax on land effectively as insufficient development of land and the moving of nomad into urban areas increases during its rapid growth. Therefore, Mongolian government has to prepare a land management system which provides the infrastructure to improve work efficiency and service quality by integrating digitalized data about land and main facilities and sharing data between related departments. This research analyzed the environment to operate the existing land management system and working environment and redesigned database. Furthermore, it integrated all the existing systems, configured service network, and made working environment for land registration, land permission, land payment management to be processed online. With this, it provides the foundation to improve quality of people's life through the preparation of long term urban planning, clean tax administration of real estate, and reconsideration of efficiency about urban infrastructure investment.

Large pressure on the growing population has increased rapid change in the LULC (land use/land cover) patterns in the watershed area. Spatial distribution of LULC information and its changes are desirable for any effective planning, managing and monitoring activities. The aim of the study is to produce the 1,50,000 scaled LULC change map for the sub-watershed, Western Moyar, India using the multi-temporal satellite image dataset of IRS LISS III images for the year 1989, 1999, and 2002. About 9 classes are extracted using onscreen visual interpretation techniques for all the three years. The change detection analysis was performed using matrix method for period I (1989-1999) and period II (1999-2002). The study reveals that the changes noticed in period II (1999-2002) is comparatively more than period I (1989-1999), which is dynamic information to protect the sub-watershed area from the deterioration and paves the way to for the sustainable development.

This study was conducted to quantitatively analyze the temporal change of green space network at multi-scales from 1975 to 2006 with the application of graph theory in Seoul, Korea. Remarkable change of connectivity was detected in green space networks at the scale ranging from 1,000 ~ 1,600 m during 30 years. Green spaces and their networks have been restoring after 1990 since forest areas had been fragmented in 1975. In 2006, we identified the important core habitat areas that can sustain diverse wildlife species and stepping stones composed of small patches that can link these core habitat areas. Green spaces showed high correlation with the relative importance value of green space connectivity. So, this study could graphically represent green space networks of Seoul City. Green spaces of core areas distributed at the northern and southern boundary, and those of stepping stones possessing the high value of betweenness centrality consisted at the middle, eastern and western boundary. These results indicate that green space network can be graphically and quantitatively explained by degree centrality, betweenness centrality and relative importance value of connectivity with the application of graph theory.
