The employment of risk management theory in Urban Disaster Management System (UDMS) has become an important trend in recent years. The viewpoint of risk management is mainly a comprehensive risk assessment of various internal and external factors, and a subsequent handling of risks. Through continuous and systematic accumulation and analysis of risk information, disaster prevention and rescue system is established. Taking risk management theory as the foundation, Organization for Economic Cooperation and Development (OECD) has developed a series of UDMS in the mega-cities all over the world. With this system as a common platform, OECD cooperates with different cities to develop disaster prevention and rescue system consisting of vulnerability assessment methods, risk assessment and countermeasures. The paper refers to the urban disaster vulnerability assessment and risk management of OECD and the mega-cities of different advanced and developed countries in the world, and then constructs a preliminarily drafted structure for the vulnerability assessment methods and risk management mechanism in the metropolitan districts of Taiwan.

The damage scale and damage area in the coast have been increased dramatically because of calamities such as typhoon. tidal wave. flood and storm. Especially. 409 cases. which reach to about $40.9\%$ of natural disasters of 1,000 cases for the recent 15 years have happened on coast area. More than $40\%$ of natural disasters also occurred every year is happening in coastland. Therefore, there is a great need to construct all related GIS database such as atmospheric phenomena (typhoon. tidal wave, flood and storm). harbor facility, harbor traffic and ebb and flow. Furthermore. the certain system should be developed and integrated with NDMS (National Disaster Management System) by using 3D web GIS technology. In this study. the coast disaster area management system was designed and developed by using 3D web GIS technique so that the coast disaster area could be monitored and managed in real time and in visual. Finally. the future disaster in coast area could be predicted scientifically.

This study analyzed the current Urban Disaster Management System(UDMS) and proposed improvements, focusing on fire-fighting. We learned the problems with the UDMS empirically, conducting a survey intended for officials in fire station in various prefectures include big city, 6 metropolitan city and Gyeonggi-do. The problems with the UDMS were classified mainly into problems with law operating system, administration system and systematic countermeasures. As a result, it was found that regions that include Seoul and other big cities manage urban disasters better than the prefectures of which Gyeonggi-do and others are parts Consequently, it is desirable to cater appropriate Urban Disaster Management Systems into each of the two parts, one for big cities and the other for prefecture.

Recently, as a part of measures against large-scale natural disasters in Korea, disaster prevention matters are strengthened in urban planning. With the introduction of the disaster vulnerability analysis system, plans for disaster prevention are being reinforced in urban planning. However, there are many problems to be solved at the stage of operation and practical application of the law. When disasters occur, we are focusing on response and recovery plans. Therefore, it is not enough to construct a comprehensive disaster prevention system to prevent disasters in advance. The established disaster prevention plan is difficult to plan management centered on disaster prevention due to factors such as economic efficiency, convenience, and comfort. This study is a basic study for supporting disaster prevention mitigation plan. For this purpose, the analysis of the actual situation of disaster prevention plan at home and abroad and improvement plan were derived. ased on these improvement plans, we have developed a method to apply the element technology of urban design to the test bed to reduce sediment disaster. The test bed was investigated and examined in the disaster hazard area of Busan and Seongnam city. And the defense technology is applied to the selected site, and the basis of the disaster prevention plan and design is proposed. If the proven techniques are reflected from the urban planning stage, it will be possible to contribute to the mitigation of sediment disaster caused by the city.

The society increased interest because the scale and size of disaster is getting gradually large. However, urban hazard mitigation management of existing system had many problems about prompt hazard mitigation (prevention, provision, confrontation, restoration) in the event of disaster. For these reasons, this paper presents ubiquitous urban hazard mitigation management system of new ideas which are fusion ubiquitous technology and urban hazard mitigation management system to solve the existing system problems.

Disaster management in Korea so far was centered on recovery efforts rather than prior mitigations. Besides, there were no systematic attempts to assemble appropriate information for even for the past disasters. In this reason, the nation has been repeatedly suffered from similar disasters. To prevent and minimize damages from disasters, it is necessary to build an information system that can gather and organize proper information and that can analyze and visualize spatial patterns of past disasters. This research aims at proposing policy measures to foster a GIS based urban disaster management system. To do so, the paper firstly takes a close look at the FGIS in the City of Taegu as an example. Then it examines the effects of GIS based urban disaster management system and suggests future directions to promote it.

Today, because human settlements are concentrated into urban area, urban planning and management technique considering the complexity, diversity, and advanced situations of urban living space is being requested. Especially, to effectively respond to large and diverse climate change driven disaster, it is necessary to develop urban planning technique including land use, infrastructure planning based on disaster vulnerability analysis. However, because current urban climate change disaster vulnerability analysis system(UC-VAS) is using census output area as spatial analysis unit, it is difficult to utilize the analysis results for specific urban planning. Instead, this study applies the grid manner to two study areas. The analysis results show that it can generate more detailed results and it can be used for detailed zoning decision by comparing with areal photos. Furthermore, by describing the limitation of the grid manner and providing professional way to secure additional scientific character and objectivity of the future urban climate change disaster vulnerability analysis system, it is expected that this study contributes to the effectiveness of system management.

Urban flooding with surcharges in sewer system was investigated because of unexpected torrential storm events these days, causing significant amounts of human and economic damages. Although there are limitations in forecasting and preventing natural disasters, integrated urban flooding management system using the SWMM engine and Web technology will be an effective tool in securing safety in operating Bi-modal transportation system. In addition, the integrated urban flooding management system can be linked with general and transportation-related disaster management system in the future. In this study, With simulated values by the SWMM, which is a core engine of the Bi-modal disaster management system, flash flooding area estimation module was developed. Thus, the SWMM system codes were modified and new module was developed and integrated with the existing SWMM interface using the Delphi programming language. The flash flooding area estimation module is fully integrated with the SWMM interface, thus the area is estimated on-the-fly inside the system.

Coastal cities suffer a great deal of storm and wind damage. The storm and wind characteristics vary between cities. Therefore, a storm and wind damage management system suited for specific characteristics is required for each coastal city. In this study, we analyze the current situation and establish the problem of storm and wind damage management system in regards to urban management, coastal management and disaster management. We also review the storm and wind damage management system for the USA and Japan. We consequently propose a plan to improve the storm and wind damage management system. As a result of the study, in terms of city management, we recommend the compulsory identification of disaster prevention districts, implementation of the integrated coastal city management plan, designation of natural disaster risk mitigation area as disaster prevention district, the division of disaster prevention district into wind damage prevention district, storm damage prevention district, erosion damage prevention district, the building of restrictions at the disaster prevention district by ordinance, etc. In regards to coastal management, we suggest the delegation of authority to delegate coastal erosion management area to the local government, the subdivision of coastal erosion management area into erosion serious area, erosion progress area, erosion concern area, the building restrictions at coastal erosion management area by ordinance, development of erosion prediction chart, etc. In relation to disaster management, we recommend the integration of "countermeasures against natural disasters act" and "disasters and safety management basic act", the local government-led disaster prevention system, the local disaster management network, and the customized local disaster prevention plan, etc.
