Purpose: This study was conducted to investigate, through experimental methods, the efficiency of passenger movement and evacuation in the event of an emergency situation on an aircraft. Method: The experiment was conducted a total of 4 times, including 3 scenarios. The three situations were evacuation without luggage, evacuation with carry-on baggage, and evacuation with carry-on baggage and carrier. In the experiment, time was measured based on recorded video. Result: The total evacuation time was found to be approximately 1.5 times higher for the evacuation with luggage, and approximately 3.5 times higher for the evacuation with luggage and 3 carriers compared to the evacuation result in a situation where nothing was carried. As a result of applying the evacuation simulation, it was found that there was a difference from the experimental results. In particular, consideration of complex situations such as carrying out and moving carriers is considered to be a situation that requires more technical research. Conclusion: Quantitive data was obtained to determine how carry-on luggage and carrier affect evacuation.

In this paper, the methodology to predict the number of deaths and possible fire propagation scenarios will be described in case of fire on a train in a tunnel. We use a probabilistic analysis method for the evaluation of possibility for each scenario and the deaths tolls are calculated with the help of the passenger evacuation simulation program. The resulting safety of passengers is displayed on a F/N graph, which could be used in part as a guideline to predict the safety level of the tunnel in fire.

In this paper, the trend of evacuation path providing or guidance systems for safety on disaster situation is analyzed. For trend analysis, 31 papers of domestic and international, 29 patents of domestic, and the finished 9 national funded projects, which have been performed for recent 15 years are analysed. As the results of analysis, the previous researches were performed in the view of the guidance systems, but there is no study that can be used for peoples in dangerous situation until now. Also it has technical limitations in using indoor positioning technology for peoples. In this paper, therefore, we propose to use the indoor positioning technology for developing a novel evacuation guidance system for peoples in dangerous situation. It can be utilized to develop a novel evacuation guidance system which is considered indoor disaster situations.

우리나라는 국제해사기구(IMO)에 "여객선 탈출지도체계의 기술개발에 관한 정보"라는 안건(IMO SSE4/INF2)을 2017년에 제출한 바 있다. 이 의제에 소개된 지능형 선박 및 인명대피 안내시스템(SEGA)은 한국해양과학기술원의 주관으로 한국해양수산부의 지원을 받아 2016년부터 2020년 3월까지 약 4년간의 프로젝트로 개발 중에 있다. SEGA는 데이터 수집과 분석, 정보 표시의 프로세스를 자동화하여 우리나라 연안에서 항해 중인 선박에 비상상황이 발생할 경우 항해자의 의사결정을 지원하는 시스템이다. SEGA 시스템을 지원하기 위해 구축된 SEGA 서버와 데이터베이스는 해양기상정보, 수심정보, 해상교통정보를 처리 한다. 또한 비상상황 시 2차 사고를 방지하기 위해 선박이 대피 할 수 있는 장소에 대한 정보를 사용자가 확인할 수 있도록 알고리즘이 설계되어 있다. 인명안전을 위해 SEGA는 비상상황 시 선박내부 구조정보와 화재 등 변수사항들을 고려하여 승객들에게 빠른 탈출을 위한 최적대피경로를 제공하며, 원격탐사기술을 이용하여 선박주변의 익수자를 탐지하도록 개발 중에 있다. 보다 상세한 내용은 항해항만학회 VTS 특별세션에서 발표할 예정이다.

We propose an emergency rescue support communication system to quickly rescue passenger ships, such as large cruise ships, when a ship sinks or a disaster such as a fire occurs. A beacon is installed in the inside of the vessel, and the position and the status of the passenger are detected in real time through the Bluetooth communication in the mobile terminal carried by the passenger and transmitted to the server. When an emergency occurs, the server sends information on the passenger to the rescue agency, informs the passenger of the emergency, and guides evacuation. As a result of simulations using the designed system, it was confirmed that the server immediately notifies all terminals when an emergency occurred in more than half of the area. This system, which detects the accident in real time and notifies all terminals in the vessel, unlike the existing system that notifies the position of the accident vessel or simply the position of the passenger in the vessel, will be helpful for the rapid evacuation and rescue of the passenger.

Concentration of people in urban areas and development around Metro make exceed the passenger number which was calculated when the Metro station was built, in the result the Metro stations are crowed this is the study on the improvement of Metro station's congestion in urban areas for ensuring the passenger safety, the space of evacuation path and promoting the more pleasant riding environment with an environmental- friendly approach.

After DAEGUE disaster, there are a lot of studying is focus on the safety of fire in korea. and Now there are taking place the modification of Urban Railway vehicle over the country. It is usually about the ability of fire resistance. But most of victims of this fire disaste in train on underground railway platform are because they could not leave the train in time and were trapped by hot gases. This study will investigate the plan of guide and evacuation plan of DAEGUE modification project and It will be compared with Madrid 8000 series metro's. and looking for reasonable and practical solution for Urban railway vehicle in Korea.

최근 포화된 도시 인구와 교통량에 대응하기 위하여 기존의 버스, 지하철 등의 대중교통 수단 이외에 광역화된 도시 영역을 빠른 시간 내에 대량의 승객이 이동할 수 있는 신개념의 교통체계로서 대심도 철도가 소개되고 있다. 철도가 광역화되고 인구 밀도가 높은 도시 영역을 빠르게 대량의 승객을 수송하기 위해서 지하 깊이 철도가 다니게 하는 것이 경제성, 효율성 측면에서 합리적일 수 있으나 편리성과 도입에 초점을 맞추다 보니 여기서 발생할 수 있는 여러 가지 안전 문제에 대한 체계적인 검토가 간과되고 있다. 대심도 터널 내에서의 다양한 교통사고와 화재를 포함하여 각종 자연 재해와 인적 재난이 대심도 교통수단의 안전에 영향을 줄 수 있다. 방재 측면에서 대심도 터널 자체의 구조와 기능, 교통수단의 기능 측면을 강조하다 보니 인명 피해, 즉 인간 그 자체의 안전에 대하여 간과하는 측면이 있어 본 내용은 국내 유사 교통 수단인 고속철도에서 심장마비 환자의 응그브이료 구축 사례와 대구 지하철 화재의 초기 응급의료 대응을 통하여 대심도 철도 사고나 응급환자 발생 시 대피와 구조의 어려움을 적절히 대처하고, 인명피해 저감 대책과 대심도 철도의 특성에 맞는 응급의료체계를 개발 방향에 대하여 제시하고자 한다.

Passenger casualties in the case of ship accidents have increased because of the increase in size and complexity of current ships (such as cruise ships). Therefore, in recent years, emergency evacuation systems are receiving increased interest so as to ensure the safety of passengers. Currently, there are only basic instructions provided, such as announcements regarding the situation, alarms, and exit signs; however, no guidance toward a proper escape route has yet been provided. To solve this problem, several emergency guiding schemes have been proposed. However, these systems ignore some of the realities of ship accidents and are impractical because various risk factors are not considered. Therefore, this paper proposes an optimal route guiding system based on an $A^*$ algorithm for emergency escape during disaster situations. This system takes into account various possible risk factors. Performance evaluation using computer simulations showed that the proposed scheme is effective and leads to safe escape routes.

Notifying emergency evacuation methods, accurate disaster location and evacuation route guidance can be very active alternatives to quickly minimize evacuation and casualties in disaster situation in the development of subway disaster prevention detection system that detects the disaster signs at the subway station early on the basis of Internet of things and leads passengers to evacuate. It's not easy to ensure perfect functioning of fire fighting facilities and equipments due to underground space structure with narrow exits. Therefore, we developed disaster provision EL Display integrated board that can induce the most efficient evacuation and the field experiment was conducted to examine the practical application in this study. Especially the applicability was verified by field application test because there is no case in which EL panels are used to evacuate disasters.
