  • The news coverage of Sewol Ferry catastrophe has reprimanded from numbers of people because of false reports and mediamorphosis such as distorted news. Thus, the purpose of this study is to examine the news coverage of television news programs about the Sewol Ferry catastrophe. Specifically, this study was conducted to figure out problems with the disaster news reports of several broadcasting stations such as, KBS, MBC, SBS and JTBC. Furthermore, the study also explores about how they reported without following the rules of disaster news coverage and policy of disaster news coverage by content analysis.

  • In this study, take a look at natural disasters and technical characteristics such as frequency, bandwidth, transmission power, and service coverage of mobile communication and terrestrial broadcasting are compared as a means to provide disaster warning service in case of natural disaster, which is increasing in recent years. In the event of a disaster, mobile communication systems that take high frequency bands, low power transmission and narrow coverage can be disabled, but terrestrial broadcasting, which uses VHF and UHF with good frequency characteristics and high transmission power and wide service coverage provides stable services. As result terrestrial broadcast is useful as emergency warning or information in case of disaster.

  • Purpose: This study analyzes the current status of open coverage of commercial mobile communication networks, which is an indicator for determining whether the disaster safety communication network call area is secured in mountainous areas, with the aim of more stable operation of the disaster safety communication network. Method: We measured the perceived communication quality on forest roads in a large mountainous area in Samcheok City and compared it with the publicly available commercial cellular network coverage data of three telecommunications companies after spatial overlapping, and found that there was a spatial mismatch between the publicly available commercial cellular network coverage and the perceived communication quality measurement results. Result and Conclusion: Therefore, for the stable operation of the disaster safety communication network in mountainous areas, it is necessary to secure additional PS-LTE mobile base stations and take measures to improve the accuracy of publicly available commercial mobile network coverage.

  • 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.

  • The number of patients with cardiovascular diseases who experience an out-of-hospital cardiac arrest (OHCA) are increasing among young adults as well as the aged population. An automated external defibrillator (AED) is vital in improving survival rates of OHCA victims. Survival rates of OHCA were shown to decline exponentially in time to defibrillation, yet studies in Korea are uncommon that captures the properties of their survival rates in examining optimal locations of AEDs. In this study, we worked on the maximal gradual coverage location problem (MGCLP) with exponential decay coverage function to decide on their optimal locations. The exponential decay coverage function mitigates the drawback of over-estimating survival rates of OHCA patients. It is expected that a more sophisticated facility location problem will be developed to identify the "emergent" characteristics of pedestrians who responds to the OHCA occurrence by incorporating random pedestrian locations and movement through simulation.

  • Purpose: Disaster as traffic accident, industrial disaster, high voltage electrical bum and flame burn of extremity have a destructive effect because of the involvement of deep structure. Generally, such injury may result in decreased function or loss of limb. In this study the successful use of the combined scapular/parascapular flap as microsurgical transfer to cover extensive defect of electrical and flame bum is reported. Material and Method: Between January 2000 and June 2001, the combined scapular and parascapular flap was used for the coverage of soft tissue defect for 7 patients were admitted to our department with high voltage electrical bum and flame burn. The recipient site were the wrist joint in 2 cases, the forearm in 1 case, the ankle joint in 1 case, the foot dorsum in 1 case, the heel in 1 case. Result: Flap survival was complete in all patients. The result of flap coverage for these deep wound was successful. Conclusion: The advantages of scapular/parascapular combined flap were coverage of the large defect, easy shaping of the flap to fit the required three dimensional configuration around the joint, non hair bearing skin of uniform thickness, minimal donor site morbidity.

  • This study was designed to look at a gap between what is reported and what is real, based on 'virtuality' shown in the media coverage of the Sewol ferry disaster. The way the Korean media reported the disaster raised serious concern in describing realities as the coverage was dotted with omitted, diluted, misleading, false and biased information, dubbed as the sinking of journalism by the Special Committee of the Korea Broadcasting Journalist Association. Virtuality can be problematic in journalism since users, when frequently exposed to 'mediated reality' or mediated presentment, often consider it actual and respond to it, rather than reacting to 'actual reality'. Many studies have found that media users tend to perceive mediated reality as an actual outside world. This paper aimed to explain signification of media reporting and limitations of user perception by reviewing major discussions and arguments on virtuality in previous research and history of thoughts. It was easy to link virtuality of mediated reality to the role of the media, which impact public opinion and change the flow of an event, and to other concepts such as the socialization of power, social control and social hegemony.

  • 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.

  • For rapid formed the ad hoc wireless backbone network in disaster scene, It is necessary for real-time deployment scheme of wireless ad hoc relay devices by first responders without pre-planning. However, in order to realize this scheme, redundant deployment should be minimized, as well as optimal location of relay devices should be selected to expand communication coverage. Therefore, in this paper, we propose a new deployment scheme of relay devices to optimize communication coverage and then through simulations showed that improved performance of algorithm.
