  • Wireless Video Sensor Networks (WVSNs) have become a leading solution in many important applications, such as disaster recovery. By using WVSNs in disaster scenarios, the main goal is achieving a successful immediate response including search, location, and rescue operations. The achievement of such an objective in the presence of obstacles and the risk of sensor damage being caused by disasters is a challenging task. In this paper, we propose a fault tolerance model of WVSN for efficient post-disaster management in order to assist rescue and preparedness operations. To get an overview of the monitored area, we used video sensors with a rotation capability that enables them to switch to the best direction for getting better multimedia coverage of the disaster area, while minimizing the effect of occlusions. By constructing different cover sets based on the field of view redundancy, we can provide a robust fault tolerance to the network. We demonstrate by simulating the benefits of our proposal in terms of reliability and high coverage.

  • Purpose: In this study, a strong wind damage prediction function was developed in order to be used as a contingency during disaster management (preventive-preventive-response-recovery). Method: The predicted strong wind damage function proposed in this study took into account the re-enactment boy power, weather data and local characteristics at the time of damage. The meteorological data utilized the wind speed, temperature, and damage history observed by the Korea Meteorological Administration, the disaster year, and the recovery costs, population, vinyl house area, and farm water contained in the disaster report as factors to reflect the regional characteristics. Result: The function developed in this study reflected the predicted weather factors and local characteristics based on the history of strong wind damage in the past, and the extent of damage can be predicted in a short time. Conclusion: Strong wind damage prediction functions developed in this study are believed to be available for effective disaster management, such as decision making by policy-makers, deployment of emergency personnel and disaster prevention resources.

  • Purpose: In South Korea, as growing the need of psychological support in disaster situation psychological assessment on stress after disaster is important to find out the factors affecting coping, and to plan intervention in the community. Method: The volunteers of Korea Redcross who live around K city, and the research team visited all homes at Jirye town, one of the high-impact area, 4 month after the typhoon. One of the family members who is over 18 years old, answered the self-report questionnaire composed of disaster experience, damage, exposure to traumatic event, and posttraumatic stress with IES-K (Impact of Event Scale-korea) He also, described his family members symptom related to re-experiencing, hyper-arousal, and avoidance. Six hundreds households were surveyed. Result: The prevalence of moderate to severe PTSD symptom was 36% of the subjects. The severity of PTSD was affected by gender, economic status and affected by damaged property, physical injury, worsening existing disease, getting infectious disease, amount of experienced traumatic event before disaster, warning, taking shelter, and subjects revealed differences in somatization as severity of PTSD. According to the description, community members had re-experiencing, hyper-arousal and avoidance. Conclusion: At a rural area, South Korea, community members have suffered from psychological distress after disaster. So psychological interventions are required as affecting factors and also to plan for warning and shelter in disaster situation is needed for preventing PTSD.

  • In Korea, There are many disasters, like the collapse of Sampung department store, the strike of severe typhoon 'Rusa' and the subway tragedy in Taegu, because of global warming, urbanization, high-density and high-rise of buildings. So, the government made 'The Framework Act' on the safe and management of disaster and 'The National Emergency Management Agency' was established. But emergency medical service systems in Korea is not growing so much. The purpose of this research is to give basic data for the development of emergency medical service systems in Disaster by comparing of disaster management systems and emergency medical systems among the nations of the world, analysing emergency medical systems in disaster in Korea and suggesting some improvement methods. The improvment methods are like this ; First, establishing the National Disaster Medical System in Korea, making the good triage by EMT, expansion of EMT's working area, developing protocols and framing of medical director increasing the working force of EMT, broad inner cavity of ambulance for treatment of patientent, supplement of professional equipments, active using of helicopters are needed in prehospital are. Second, equal establishment of emergency medical center and increase of working force of emergency medical team are needed in hospital area. Finally, enforcement of the dispatcher's qualification, smooth communication among EMSS systems and actualization of medical direction through screen are needed in the Telecommunication system.

  • This study analyzes the current status of Korea's legal system was a disaster in the rural region and to identify problems. There are many problems in rural region despite the specificity and uniqueness of the area significantly as compared to the city did not receive such consideration as to distinguish the area as part of the institutional election strategy. Through this study, we analyze the problem more effectively and to respond proactively to the disaster in the rural region. And it sought a solution to the problem and its legal system.
