A marine helicopter should remain sufficiently upright to permit safe evacuation of all personnel with a flotation system. And the rule requires that after ditching in water, the adequate flotation time will allow the occupants to leave the rotorcraft. To this end, stability test of the emergency flotation system for Korean marine helicopter was performed by using "Froude scaling method" in water tank. Test configuration and conditions were determined in consideration of the helicopter loading condition and related specifications. Test results meet the stability requirements at sea state code 4 and sea state code 2 with puncture conditions.

Purpose: The purpose of this study was to investigate the disaster experience (accidents, education etc) and the concern for disaster preparedness of college students. Methods: This research design was a descriptive study. Data were collected from November 1, 2011 to December 30, 2011 and analyzed by the SPSS PASW statistics 18.0 program. Results: There were statistical significances in major (p<.050), grade(p<.001), and a completed disaster class(p<.001) between general characteristics and concern for disaster preparedness. The major disaster events that occurred from 2003 to 2010 in Korea were the 2007 Taean oil spill (85.4%), the 2003 Daegu subway fire (82.7%), and the 2008 Sungnyemun fire (62.9%). The possible disaster events in Korea were hurricanes, floods, fires (including wildfire), and the shutdown of communication lines. Subjects learned about cardiopulmonary resuscitation (18.2%), first aid for bleeding and fractures (17.8%), a fire drill (14.3%), and an escape drill for an earthquake (14.0%). They wanted to learn the fire drill (11.33%), the escape drill for an earthquake (9.7%), a war drill (9.0%), a disaster confrontation drill on the subway (8.6%), and a fire and explosion evacuation drill (8.4%). Half of subjects were not prepared with emergency supplies for disasters because they thought that a disaster would not occur. Conclusion: It is necessary to develop the disaster educational programs according to subject's demands in Korea.

Caused by the Cheonanham attack and the Yeonpyeongdo bombardment occurred a few years ago, and the recent North Korea's nuclear test, the war crisis between South and North Korea has been increasing. Accordingly, an interest in obtaining a temporary residential space, for the case of the outbreak of war, where people can reside safely over a period of time has been escalating. However, in the disaster relief planning guidelines of the National Emergency Management Agency, the standards on the temporary residential spaces in preparation for storm and flood or earthquake are included, but the standards on the ones in responding to war are not yet equipped. In particular, the standards on the underground temporary residential spaces that can accommodate massive victims should be developed in preparation. In this study, through a requirements analysis based on the survey of war victims and a comparative analysis between disaster-related laws and regulations, the direction of relevant system improvement for the utilization of temporary residential spaces in responding to war is established.

Many railway safety measures are carried out after Daegue subway fire accident. Such as replacement of train interior material, fire extinguish and toxic gas evacuation facilities, exercise on emergency response, setting up of national safety management system, and safety technology research. But these safety measures are not considered by system safety due to lack of risk and hazard information. In order to assess fire risk on system level, we proposed hazard events and causes classification for railway fire accident risk analysis.

We report a case of an acute spontaneous epidural hematoma (EDH) due to skull base metastasis in a 46-year-old male patient with hepatocellular carcinoma (HCC). The patient presented with the acute onset of severe headache followed by unconsciousness, and computed tomography showed a large EDH in the right temporal and parietal lobes with midline shift. Emergency evacuation of the EDH was performed, and the hemorrhage was determined to be secondary to skull base metastasis of HCC.

The possible air pollution problems in a proposed underground highway are discussed using carbon monoxide (CO) as an indicator. Carbon monoxide concentrations in the underground highway depend on several factors, including the size of tunnel, the number of automobiles, the CO emission rate, and the tunnel ventilation rate. Using the estimated values, CO concentrations in the underground highway can be predicted. Without proper ventilation system, CO concentration in the underground highway can be dangerous level. However, the cost of operating the mandatory mechanical ventilation system may be tremendouslyy high and may be technically unrealistic to implement. If the underground highway is constructed with proper ventilation system, a continuous air pollution monitoring system with alarming function must be installed to alert personnel of serious air pollution built up in the underground highway. Traffic must be restricted, whenever the inside air pollution levels exceed agreed values. Short distances between evacuation exits are necessary for emergency situations or malfunction of ventilation system.

방재계획의 하나인 대피장소 및 대피경로의 결정은 방재계획 중 가장 기본이 되는 사항으로 재해발생 시 대비가 적절치 못하면 대규모 인명피해가 발생할 우려가 있기 때문에 결정에 신중을 기해야 한다. 대피장소 및 대피경로의 결정은 직접 대규모 인원이 참여한 모의실험을 실시하여 효율적이고 안전한 방법을 찾는 것이 가장 바람직하다. 그러나 이러한 접근은 현실적으로 불가능하기 때문에 본 연구에서는 대상 지역의 지진해일 대피 시뮬레이션 모형을 제작하고 이를 적용하여 최적의 대피장소 및 대피경로를 지정할 수 있도록 하였다. 이러한 접근을 통하여 실제 지진해일 발생 시 주민들이 가장 빠르고 안전하게 대피하도록 할 수 있으며, 나아가 효율적이고 안전한 방재계획 수립에 큰 역할을 할 수 있을 것이다. 본 연구에서는 과거 지진해일로 인한 피해 경험이 있는 삼척항을 지진해일 대피 시뮬레이션을 위한 대상지역으로 선정하였다. 또한, 현장 조사를 실시하여 대상지역의 지형특성을 고려한 결과를 토대로 지진해일 대피 시뮬레이션에 앞서 필요한 가상 시나리오를 작성하였고 지진해일 대피 시뮬레이션을 통해 비상대처계획(EAP, Emergency Action Plan) 수립에 필수 사항인 대피계획을 검토하였다.

본 연구는 안전불감증으로 인하여 발생되는 인명피해 재난사고를 예방하고자 증강현실(Augmented Reality)기반 BLE 비콘(Beacon)을 사용하여 영화관 내 비상대피로 안내를 수행하는 시스템을 제안한다. 기존에 GPS를 사용하여 위치기반 증강현실 서비스가 제공되었다면 Beacon 위치정보를 탐색하는 것이 실내 위치기반 증강현실 서비스에서 더 정밀한 결과를 얻을 수 있다. 영화관 내에서 발생할 수 있는 화재, 가스, 붕괴 등 다양한 사건을 그래픽처리 하여 화면에 출력시키고 그에 따른 이벤트를 발생시켜 사용자가 가장 가까운 비상구의 위치로 대피할 수 있도록 네비게이션 역할을 하도록 하며, 사전에 실제 대피로를 체험할 수 있는 방안을 제시한다.

Many long railway tunnels without emergency evacuation system or ventilation system are under construction or in-use in Korea. In the case of tunnel-fire, many fatalities are occur in current condition. Current safety level is estimated in this study, for the efficient investment on safety. But so many uncertainties in major input parameters make the safety estimation difficult. In this study, probabilistic techniques are applied for the consideration of uncertainties in major input parameters. As results of this study, accident scenarios and survival ratio under tunnel fire accident are determined for various conditions.

The 2005 west off Fukuoka earthquake with Mjma 7.0 occurred in the vicinity of Fukuoka city with 1.4 million populations, which had been regarded as rather seismically inactive in Japan. The strong motion records by K-net indicated PGV of 64 cm/s in Fukuoka city and some condominium buildings sustained extensive non-structural damages. In this study, we conducted a questionnaire survey for residents of 8 condominium buildings located in the downtown area of Fukuoka city after the earthquake. The results indicate that damaged nonstructural walls and distorted doors disrupted evacuation route for many occupants, and furniture and content damage on upper floors became severer resulting in higher rates of human casualty. Earthquake preparedness for indoor safety was raised after the earthquake, though further safety measures can be advised. In the phase of post-earthquake emergency and restoration period, residents' management organizations play important roles, so that neighborhood activities to promote communication networks are important in urban environment with aging population.
