  • The purpose of this study is to determine the rapid saving of life through the drones when natural disasters such as earthquake and fire occur. Drones are equipped with riders, temperature, hazardous gas sensors and wireless cameras are registered with the application server for monitoring the disaster site and real-time monitoring functions are performed to identify the situation on site before rescuing personnel are active. When monitoring finds a person to save, the application server provides real-time image information for effective life-saving.

  • The LTE system decided to build an integrated disaster safety communication network in order to cope with disasters quickly after the April 16, 2014 disaster, and 333 agencies in 8 areas will build a unified disaster safety communication network. It plans to integrate LTE-R, a railway integrated wireless network, and LTE-M, a land-based communication network, in the 700MHz band. LTE-R, a wireless integrated network, and the Ministry of Land, Transport and Maritime Affairs, are currently using VHF and TRS, which are voice communication-oriented communication systems, in order to cope with demand for high-speed railway service, With this possible LTE-R, it is possible to provide advanced services such as radio-based train control and improve railway safety. The company plans to invest KRW 1.1 trillion in new routes to be launched in 2018 and the existing route to be improved in the future, and to build up all routes of general and high-speed railways to LTE-R by 2027.

  • This paper presents a novel driving system by the humanoid robot to drive a vehicle in disaster response situations. To enhance robot's capability for substituting human activities in responding to natural and man-made disaster, the one of prerequisite skills for the rescue robot is the mounted mobility to maneuver a vehicle safely in disaster site. Therefore, our driving system for the humanoid is developed in order to steer a vehicle through unknown obstacles even under poor communication conditions such as time-delay and black-out. Especially, the proposed system includes a tele-manipulation interface and stable navigation strategies. First, we propose a new type of path estimation method to overcome limited communication. Second, we establish navigation strategies when the operator cannot recognize obstacles based on Dynamic Window Approach. The effectiveness of the proposed developments is verified through simulation and experiments, which demonstrate suitable system for driving a vehicle in disaster response.

  • This study compared news coverage of national and international disasters, Hurricane Katrina and the Haiti Earthquake, using textual analysis of The New York Times and The Washington Post. The results reveal that media framing of the historical cases developed in three stages upon the development of post-disaster relief: (1) Call for humanitarian assistance; (2) New Orleans under anarchy and hopelessness vs. Haiti under scrutiny with hope; and (3) Katrina effects. By framing the outcomes of the hurricane as the "Katrina effect," the media used the disaster as a reference point to explain other economic and political issues. In addition, analysis of relevant statements and press releases confirmed that different social actors involved in the relief process, such as donors, facilitators, and beneficiaries, contributed to the media framing of the issue, although the facilitators were most successful in transferring their own frames to media frames. This study makes important contributions to the field as it looks beyond traditional relationships between quantitative measures of media attention and aid allocation. For governmental and nongovernmental organizations in the area of humanitarian assistance, the findings of this study will assist them in media-relations in the future.

  • This research paper surveyed the awareness of general administrative officials who oversee the disaster management and firefighting officials who take part in emergency rescue work in local governments on disaster response exercises. The result of the survey showed that both officials acknowledged the need of the equipment used in disaster response exercises, securing the budgets for exercises, establishing a network among related institutions, reflecting actual conditions and local characteristics to the exercises, reflecting the result of exercise evaluations to the disaster response manual and next exercises, and securing a command communication system required for exercises.

  • Until now, Korea carried out disaster management under the perception that the central government or the local government bodies are totally responsible. However as the size of disasters become larger, the capacity of the public disaster management did not live up to the expectations. To analyze this issue, this research conducted interviews on disaster response readiness by "individual resident-residents cooperation-public/private collaboration" according to each preparedness-response-recovery stage, as resident representatives (Head of Ri, Head of Tong) as subjects. Based on the interviews, surveys were conducted to deduct the necessary factors needed for the general residents to exhibit disaster prevention capabilities. The surveys consist of 6 factors-risk perception, evacuation inductively, individual evacuation response, disaster prevention system, lookout & precaution, information communication.

  • Earthquake disaster frequently happens in Shizuoka Prefecture and it is commonly predicted that a giant earthquake(Tokai Earthquake) could occur in the near future. When a giant earthquake happens, extensive damage of lifelines will be expected. It is considered that the collection of damage information and the establishment of a communication network system are very important in order to restore lifelines quickly. And geographic information system(GIS) might playa very important role to grasp the spatial information of lifeline damage in a natural disaster. The authors' group had a research project to study a lifeline restoration support system with image processing and ad hoc networking in a natural disaster. The objectives of this presentation are to introduce our project and to show some results of our study. The authors finally constructed the GIS for the integration of damage information acquired by image processing and ad hoc networking.

  • Twitter is a microblogging service that allows its user to share short messages called tweets with each other. All the tweets are visible on a public timeline. These tweets have the valuable geospatial component and particularly time critical events. In this paper, our interest is in the rapid detection of disaster events such as tsunami, tornadoes, forest fires, and earthquakes. We describe the detection system of disaster events and show the way to detect a target event from Twitter data. This research examines the three disasters during the same time period and compares Twitter activity and Internet news on Google. A significant result from this research is that emergency detection could begin using microblogging service.

  • There was heavy rains that happened for 23 days consecutively in 2006. Many regions have suffered because of rains and among them In-Je and Pyung-Chang area are the most suffered areas at that time. I conducted field survey at those two regions. The case of other damaged regions also reviewed in this paper and volunteer activity of volunteer groups is reviewed. I intended to make clear the volunteer activity system through analysing need capacity of volunteers. Main suggestions are as below. In management system, the nexts are discussed. Improving the ability of village headmen and volunteer groups that manage relief stuffs at the first level and cooperating method with companies are discussed. Supporting system for isolated regions and necessity about developing operating manual are suggested. In education system, specialized education for different disaster areas, field orientation education, and training managerial positions are suggested. In supporting system, improving NDMS(National Disaster Management System), computerized program for volunteer management, insurance for volunteers, issuing a confirmation of volunteering activity, securement of emergency communication system, budget for prevention and donation are also suggested.
