세월호 참사보도는 오보와 왜곡 축소 보도, 그리고 언론 윤리에 어긋나는 자극적인 보도 등으로 인해 국민들로부터 많은 질책을 받은 바 있다. 따라서 본 연구는 우리나라 방송사들이 세월호 참사를 어떻게 보도 했는지 학술적인 분석을 시도해 보고, 재난보도가 지니는 의미를 조명해 보고자 했다. 연구결과, 우리나라 주류 방송사인 지상파 방송사들은 재난보도가 지켜야 하는 보도의 정확성과 객관성에 미흡함을 보였으며, 언론이 재난보도 과정에서 지양해야 하는 선정성과 오보 양산 등 재난보도의 문제점에서 벗어나지 못하고 있는 것으로 나타났다. 그러나 JTBC의 경우 주류 방송사들의 보도와 달리 재난보도 과정에서 사건 발생의 원인규명과 재발 방지를 위한 대안을 제시하고, 지속적인 사회적 이슈로 논의할 수 있는 장을 마련한 것으로 나타났다.

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.

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.

노년층뿐만 아니라 청년층에 속하는 성인들 사이에서도 병원 외 심장정지(OHCA)를 겪는 심장질환자의 수가 증가하고 있다. 자동심장충격기(AED)는 병원 외 심장정지 환자의 생존율을 개선하는 데 있어 긴요하다. 심장정지 생존율은 제세동 시간에 대하여 지수적으로 감소(decline exponentially)하는 것으로 밝혀졌으나, 자동심장충격기의 최적 배치에 있어 심장정지 생존율의 이러한 특성을 반영한 국내 연구가 미미한 상황이다. 본 연구에서는 자동심장충격기의 최적 입지를 결정하기 위하여 exponential decay coverage 함수를 갖는 최대 gradual coverage 입지 모델에 대하여 고찰하였다. exponential decay coverage 함수는 심장정지 환자의 생존율에 대한 과다추정을 완화한다. 향후 시뮬레이션을 통하여 랜덤한 행인 위치 및 이동을 반영함으로써 행인의 심정지 대응에 있어 창발적인(emergent) 특징을 식별할 수 있는 시설 입지 모델이 개발될 것으로 예측된다.

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.

본 연구는 세월호 참사 보도에 드러난 '가상성'을 중심으로 매개된 현실과 실제 현실의 간극을 조명하고자 기획되었다. 방송기자연합회 저널리즘 특별위원회는 한국 언론의 세월호 보도 양상을 가리켜 저널리즘의 침몰이라고 명명할 만큼 세월호 보도는 현실 반영에 커다란 문제점을 드러냈다. 언론 보도의 가상성이 문제가 되는 것은 실제 현실보다 보도된 현실, 즉 매개 표상들을 더욱 많이 접촉하고 경험할 때, 수용자는 '실제 현실'에 근거하여 행동하기보다는 '매개된 현실'로부터 받아들인 것을 실제 상황이라 여기고 이에 근거해 반응한다는데 있다. 많은 연구에서 매체의 수용자들은 매개현실을 실제 외부세계로 받아들이는 것으로 관찰된다. 본 연구는 선행연구와 사상사에서 다루어진 '가상' 개념에 대한 중요 담론을 검토하여 매개현실의 문제와 한계를 설명하고자 하였다. 매개현실의 가상성은 여론에 영향을 미칠 뿐만 아니라 권력의 사회화, 사회 통제, 사회주도권 개념들과도 쉽게 연결 지을 수 있었다.

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.

재난현장에서 신속한 애드혹 무선 백본망을 형성하기 위해서는 사전계획 없이 초동 대응요원들에 의하여 무선 애드혹 중계장치를 실시간으로 배치하는 기법이 필요하다. 그러나 이를 실현하기 위해서는 중계장치의 중복배치 최소화뿐만 아니라 통신권역 확장을 위한 중계장치의 최적 위치를 선정할 수 있어야 한다. 따라서 본 논문에서는 통신권역을 최적화하기 위한 새로운 중계장치 배치기법을 제안하고 모의실험을 통하여 알고리즘의 성능이 향상되었음을 보였다.

This study was conducted to improve the stability of cut slopes of forest roads in granitic weathered soil areas. The study area is a national forest road (road length 28.48 km) in Pyeongchang-gun, Gangwon-do. After data collection, a statistical analysis was performed using IBM SPSS (Ver. 26.0). First, the correlation analysis showed that structure, slope position, soil erosion, slope, and aspect (N, S) were correlated with vegetation coverage (p < 0.05). Elapsed years, slope distance, and aspect (E, W) were found to have no correlation with vegetation coverage. (p > 0.05) Second, one-way ANOVA and Kruskal-Wallis test results showed that vegetation coverage was worse when the slope was located at the top or the middle of the slope than at the bottom of the slope. In addition, the site with sheathing and gabions showed good vegetation coverage when compared with the site without structures. In the case of soil erosion, areas with severe damage and moderate damage showed worse vegetation coverage. Therefore, it is necessary to strengthen the slope angle of the cut soil of the granitic weathered soil area from 1 : 0.5 - 1.2 to 1 : 0.8 - 1.5. In addition, structures such as sheathing and gabions should be installed on granitic weathered land.
