Remote response technology has advanced to the extent that a robot system, if properly designed and deployed, may greatly help respond to beyond-design-basis accidents at nuclear power plants. Particularly in the aftermath of the Fukushima accident, there is increasing interest in developing disaster robots that can be deployed in lieu of a human operator to the field to perform mitigating actions in the harsh environment caused by extreme natural hazards. The nuclear robotics team of the Korea Atomic Energy Research Institute (KAERI) is also endeavoring to construct disaster robots and, first of all, is interested in finding out to what extent safety benefits can be achieved by such a disaster robotic system. This paper discusses a new approach based on the probabilistic risk assessment (PRA) technique, which can be used to quantify safety benefits associated with disaster robots, along with a case study for seismic-induced station blackout condition. The results indicate that to avoid core damage in this special case a robot system with reliability > 0.65 is needed because otherwise core damage is inevitable. Therefore, considerable efforts are needed to improve the reliability of disaster robots, because without assurance of high reliability, remote response techniques will not be practically used.

Natural disasters can cause major accidents in chemical facilities where they can lead to the release of hazardous materials which in turn can result in fires, explosions or toxic dispersion. Technological disasters triggered by natural disasters are referred to as NaTech(Natural Disaster Triggered Technological Disaster). These trends increase the probability of catastrophic future disasters and the potential for mass human exposure to hazardous materials released during disasters. In the present study, we proposed some methods for effective disaster management by conducting case study of major NaTech. First, establishing information sharing system of chemical accident for stakeholders and improving disaster manuals and standards of central and local government and co-operation support system. Second, activating information service of emergency planning and community right to know. Third, improving the integrated chemical accident database including NaTech accidents.

Disadvantaged from disaster response training and disaster safety education who people are vulnerable to disasters when faced with disasters. The vulnerability of these disaster response will be linked to the desire for disaster information. Therefore, using smartphone to provide timely disaster information will be an effective disaster response service that enables disaster vulnerable people to avoid disaster efficiently. In particular, the importance of using smartphone as a part of the body will become more and more important in everyday situations when information is acquired through smartphone. In this study, Through a survey of traditional market traders, I can find out that the desire of elderly women, who are weak in disaster, to receive disaster information through smartphone text service is relatively strong. Based on the results of this study, I expect that the opportunity to improve disaster response capability through smartphone text service will be provided to elderly women who are weak in disaster.

Previous disaster management system in Korea was focusing on post-disaster, recovery phase. However, modern disaster management system should be focusing on the mitigation activities to minimize human and property damages based on the proper prediction and forecast of various natural disasters and timely dissemination of disaster information to the people. Recently, more frequent and larger scaled disasters have been reported around the globe, mainly due to the environment change not only by physical anomalies such as climate change but also by socio-economic transformations such as urbanization and industrialization. This study describes current practices in disaster management for climate change adaptation of advanced countries and a possible disaster management standard system that can be applied in Korea, based on the case studies on the European countries who are improving their disaster management systems against climate change.

Compound disaster is the type that increases the impact affected by two or more hazard events, and attention to compound disaster and multi-hazards risk is growing due to potential damages which are difficult to predict. The objective of this study is to analyze the possible impacts of post-fire landslide scenario quantitatively by using TRIGRS (Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Analysis), a physics-based landslide model. In the case of wildfire, soil organic material and density are altered, and saturated hydraulic conductivity decrease because of soil exposed to high temperature. We have included the change of soil saturated hydraulic conductivity into the TRIGRS model through literature review. For a case study, we selected the area of $8km^2$ in Pyeongchang County. The landslide modeling process was calibrated before simulate the post-wildfire impact based on landslide inventory data to reduce uncertainty. As a result, the mean of the total factor of safety values in the case of landslide was 2.641 when rainfall duration is 1 hour with rainfall intensity of 100mm per day, while the mean value for the case of post-wildfire landslide was lower to 2.579, showing potential landslide occurrence areas appear more quickly in the compound disaster scenario. This study can be used to prevent potential losses caused by the compound disaster such as post-wildfire debris flow or landslides.

In the case of Korea, research on traffic management is insufficient to cover the increasing incidence of disaster. Furthermore, many of the traffic management manual does not touch up on how to administer/manage in case of disaster, except for the one made by 'Korea Expressway Corporation.' In response to this issue, this research is based on a thesis to establish concept of guideline for traffic management in the case of an disaster. In order to achieve this goal, there has been an analysis of the American's manual, molded and changed to be Korea-specific. In the future, based on the u-T circumstances are established, traffic management will become much more efficient. This paper presents important details and ways of management for each step of an disaster event: prevention, preparation, response and restoration.

Purpose: The fields manuals which is managed by the each disaster types are the integrated guideline. When the disaster occurred, all kinds of SOPs which are described in the manual does not need. Therefore, the person in charge is confused which SOP is executed. In this study, we propose the disaster response process model based on the specific disaster situation case. Method: Firstly, we define the disaster situation cases which is mentioned in the field manual, and then, we develop the disaster response process model including indispensible SOPs for the specific disaster situation case. As a verification and feedback process, we apply the model to Safety Korea Exercise scenario. Result: We developed SOP model and disaster response process model reflecting the concept of the disaster situation case. Conclusion: Safety Kore Exercise scenario reflecting the developed model may continuously upgrade the field manual.

This study demonstrates a basic concept and designing direction for the realisation of disaster prevention planning in u-City(u-BangjaeCity) that is from establishing a planning system in terms of the areas of professional disaster and safety management for the national disaster management. and designing disaster or safety management system via using ubiquitous technology for the scientific disaster management. In order to realise u-City it is necessary to maps out interrelation amongst various services such as traffic, environment and disaster prevention. Domestic and international case studies regarding the tendency of disaster prevention planing in u-City and its analysis could be the fundamental resource in order to develop the standard model of u-BangjaeCity.

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.
