Increasing urban sprawl and climate changes have been causing unexpected high-intensity rainfall events. Thus there are needs to enhance conventional disaster management system for comprehensive actions to secure safety. Therefore long-term and comprehensive flood management plans need to be well established. Recently torrential snowfall are occurring frequently, causing have snow traffic jams on the road. To secure safety and on-time operation of the Bi-modal tram system, well-structured disaster management system capable of analyzing the urban flash flooding and snow pack melt/freezing due to unexpected rainfall event and snowfall are needed. To secure safety of the Bi-modal tram system due to torrential snowfall, the snow melt simulation capability was investigated. The snow accumulation and snow melt were measured to validate the SWMM snow melt component. It showed that there was a good agreement between measured snow melt data and the simulated ones. Therefore, the Bi-modal tram disaster management system will be able to predict snow melt reasonably well to secure safety of the Bi-modal tram system during the winter. The Bi-modal tram disaster management system can be used to identify top priority area for snow removal within the tram route in case of torrential snowfall to secure on-time operation of the tram. Also it can be used for detour route in the tram networks based on the disaster management system predicted data.

Life Environment is rapidly changing and large scale disasters are increasing from the global warming. Although the disaster repair resources are deployed to the disaster fields, the prevention of the disasters is the most effective countermeasures. the disaster sign data is based on the rule of Heinrich. Automatic extraction of the disaster sign data from the web is the focused issues in this paper. We defined the automatic extraction processes and applied information, such as accident nouns, disaster filtering nouns, disaster sign nouns and rules. Using the processes, we implemented the disaster sign data management system. In the future, the applied information must be continuously updated, because the information is only the extracted and analytic result from the some disaster data.

This paper examines the social development process of technological innovation for national emergency management. There are relatively few studies on how technological innovations are developed and deployed within social context. This paper investigates innovation processes within social contexts and the role of innovation actors such as citizens, government, and private sector. The the Real-time Disaster Management System (RDMS) is an innovation for citizens to transmit digital images and video clips on disaster toward professional organizations to respond to disasters. This case shows how an innovation in disaster management was developed by social interactions, how open innovation mechanism was deployed, and how end-users involved in innovation processes for disaster management. Finally this paper suggests implications to accelerate innovations for social welfare and social change.

New governance in the area of disaster management(New Governance) of the Safety Building in the form of public-private network as required in this era, SWOT can provide a strategic way to build public-private partnership recognized the necessity for a more efficient way. Between government agencies, private organizations and government and private organizations for the network between the systematic approach based on mutual trust, and participation by the activation of the meaning of seeing places studied. Partnership for Disaster Management as a result of the settlement than if the existing disaster management system for disaster response system more effective and efficient functioning in reducing human and material damage is expected to contribute are getting out.

Damage on assets and lives caused by natural disasters can be minimized by the provision of early warning information and preventive activities. In this sense, the importance of a disaster early warning system continues to increase. This study specifies the kinds of early warning systems depending on the type of natural disasters such as typhoon, flood and heavy snow. The mechanism for information transmission and status of early warning operations are analyzed. Through this analysis, the urgent need to establish a national integrated early warning transmission system is emphasized. In addition, this study offers methods to prevent unnecessary overlapping of investments by establishing an organic mechanism among individual early warning systems. Based on the standardization of disaster-related information, this study also provides methods to improve the efficiency of disaster early warning systems by organizing a permanent team for handling the systematic management and operation of the system.

Korea has faced with the problem of the whole national disaster safety due to the Sewol-ho and it reminded people and government of the importance of national safety. It is needed to establish the national unified network especially focused on the disaster site and also improved in the fields of law, system and organization related to the management of disaster. To do this, PS-LTE technology must to be adopted to the network and 700MHz is the most efficient bandwidth for the network. At the same time, we have to improve the management system for the response of disaster including standard procedure and the platform of disaster response system. In order to establish realistic and efficient emergency communications network, it is effective to build own network and use leased networks together. And the cost is estimated about 5.2 trillion won.

Most of steep slope failures occurring in Korea have appeared during the localized heavy rain period, whereas the evaluation model of a disaster vulnerability analysis that has been proposed to date, has been prepared in consideration only of external factors comprising geographical features. This study calculated a wetness index and a contributory area which delivers moisture to the upper slant surface during the rainfall period, and also conducted a disaster vulnerability analysis in consideration of the convergence of surface water as well as the water system created during the occurrence of rainfall by including a curvature that shows a close relevance with the shape of the minute water system that is created temporarily during the occurrence of rainfall and with the convergence and divergence of surface water. When compared with a steep slope failure occurring within a selected model district in order to verify the prepared disaster analysis, a landslide occurring in the model district had emerged in a region in which the disaster vulnerability analysis was high and the density of the minor water system was also high. If these research results are extended nationwide, it is the most effective to use a disaster vulnerability analysis and the density of the minute water system; and it is supposed to be the simplest and the most effective method for preparing a disaster analysis of mountainous land shape such as the model district.

In recent years, lots of damages appear frequently due to cyber terrorism and natural disasters such as typhoon 'Chaba', earthquake at Kyeongju. The damages lead to people's anxiety and public institutions connected directly with them also can't be free from the threat situation. In addition, public institutions must prepare business continuity issues with the highest priority in the event of disasters because they are closest with people's safety. However, preceding researches suggest needs of disaster mitigation activities management system or central office oriented top-down BCP establishing system. In this study, We grasp the current status of public institutions's business continuity plan(BCP) against disaster and we propose an efficient bottom-up method for structuring the BCP of public institutions.
