  • Among the fire incidents in Korea over the past decade, building fires are the most common, and property and human casualties are the most common. However, the existing fire fighting system does not only inform the location of emergency exits and guide safe routes to help casualties evacuate smoothly. A system was proposed to help successful evacuation by distinguishing vertical and horizontal characteristics using spatial characteristics. In this study, an effective evacuation system was proposed by predicting fires using temperature detection sensors and smoke sensor values, and calculating the optimal evacuation path through the Dijkstra algorithm.

  • 최근 풍수해 현황 분석(국민안전처, 2016)에서는 2003년 이후 태풍 루사와 매미와 같은 대형태풍이 최근에 발생하지 않아 대부분 하천급류로 인한 인명피해가 대부분이라고 언급하였다. 최근 풍수해로 인한 피해가 발생하지는 않았지만 호우/태풍이 발생할 경우 인명보호와 불편해소를 최우선에 두고 각종 정책들을 선제적으로 추진하고 있어 홍수범람발생 예상지역에 대한 인명피해 분석은 반드시 필요하다고 판단된다. 최근들어 인명피해를 평가하는 기술은 피해자료로부터 비교적 간단히 분석되는 경험적 방법에서 2차원 동적 수리모형과 연계, 그리고 정밀한 인구, 건물 등의 자료를 활용하여 대피율, 사전경보 등 인명피해에 영향을 미치는 다양한 요소를 복합적으로 고려하고 개념적이고 기계적 방법으로 발전하는 추세이다. 우리나라의 경우 인명피해 평가와 관련한 연구사례가 거의 전무한 상태이고, 치수경제성분석에서 제시하는 침수면적에 기반한 간략한 방법만이 실무에서 활용되고 있다. 최근 국외에서 제시한 접근방법은 본 연구에서의 개발하고자 하는 목적과 방향에 부합하지 않다고 판단되며, 국내 실정을 고려할 때 주요 영향인자를 추가하고, 특히 노출인구, 인명 인벤토리의 해상도를 높이는 데 주안점을 두고자 한다. 홍수로 인한 인명피해 발생확률은 사후분석의 일환으로 침수흔적도를 통해 총 2개의 침수구간을 설정한 후 Census data를 활용한 위험인구(Population at Risk, PAR)를 산정한후, NDMS 인명피해 자료를 활용하여 침수구간별 인명피해 발생확률을 제시하였다. 여기서 제시한 침수구간의 경우 데이터의 축적정도에 따라 구간을 세밀화 할 수 있는데, 본 연구에서는 총 2개구간(0-1m, 1m 이상)으로 계략화 하여 제시하였다. 본 연구에서는 4개의 지자체의 인명피해 자료를 통해 인명피해 발생확률을 산정하였으며, 해당내용을 시범유역의 빈도별 침수구역도에 적용하여 인명피해 발생을 분석하였다. 해당 연구결과의 경우 인명피해에 대한 명확한 결과를 유추하는데에는 한계가 있지만, 인명피해에 기반한 해당지역의 장래피해규모를 예측하는 데에는 기초가 될 수 있을 것으로 판단된다.

  • 화재 시에는 발생 유독가스와 연기로 인하여 많은 인명 피해가 날 수 있으며, 따라서 주요 건물이나 시설에는 국민의 생명을 보호하기 위한 화재용 긴급대피마스크를 갖추도록 권고하고 있다. 하지만 그 성능에 대한 의혹이 꾸준히 제기되고 있어, 사용자인 국민으로서는 늘 불안한 심정이다. 이에 본 연구에서는 현재 국내 시판되고 있는 화재용 긴급대피마스크 5종에 대하여 KS 주요 시험항목에 의거하여 성능시험을 실시하고, 문제점을 진단하였다. 실험 결과, 일부 제품에서는 성능기준에 미치지 못하는 경우가 발생하였으며, 이는 화재 시 국민의 안전을 크게 위협하는 중차대한 사안이므로, 시급히 부적격 제품의 판매를 제한하고 성능기준에 맞는 제품만이 판매될 수 있도록 법적인 보완이 이루어져야 하는 것으로 나타났다.

  • Lately, losses and damage from natural disasters have been increasing. Researchers across various fields in Korea are trying to come up with a response plan, but research for evacuation plans is still far from satisfactory. Hence this paper proposes a model that could find an optimized evacuation route for when disasters occur over wide areas. Development of the model used methods including the Dijkstra shortest path algorithm, feasible path method, genetic algorithm, and pareto efficiency. Computations used parallel computing (SPMD) for high performance. In addition, the developed model is applied to a virtual network to check the validity. Finally the adaptability of the model is verified on a real network by computating for Gumi 1stNational Industrial Complex. Computation results proved that this model is valid and applicable by comparison of the fitness values for before optimization and after optimization. This research can contribute to routing for responder vehicles as well as planning for evacuation by objective when disasters occur.

  • The purpose of this study is to reveal the effects of the number of users and their spatial distribution on the evacuation time in a road tunnel in the event of a fire. An agent-based evacuation model was implemented using Netlogo following the ODD protocol. The proposed model illustrates how the evacuation behavior of one can hinder others across different evacuation environments. Simulations show that evacuation time increases with the number of users when they are randomly located in a road tunnel.

  • In this study, a real-scale stairway model was constructed to analyze the evacuation safety of human life due to the change of flooded stair flow. In the experiment, the water depth and flow velocity at each stage of the stairs were measured and the specific force per unit width was calculated. Using the calculated the specific force per unit width, the evacuation safety of each steps of stairs according to the change of the flooded stair flow was presented. Finally, the depth of water measured by the experiment and the evacuation safety graph of "Ishigaki" by the specific force per unit width were combined to analyze the evacuation safety by depth. As a result, it has been found that evacuation of adult man is difficult without help at the flow depth of 0.20 m or more. And it has been found that evacuation of adult women and elderly men are difficult without help at the flow depth of 0.15 m or more. Finally, it has been found that evacuation of elderly women is difficult without help at depth of 0.13 m or more.

  • Flood damage is occurring all over the world, and the number of people living in flood-prone areas reached 86 million, a 25% increase compared to 2000. These floods cause enormous damage to life and property, and it is essential to decide on an appropriate evacuation in order to reduce the damage. Evacuation in anticipation of a flood also incurs a lot of cost, and if an evacuation is not performed due to an error in the flood prediction, a greater cost is incurred. Therefore, in this paper, we propose a flood risk determination model using the CNN model to enable evacuation at an appropriate time by using the time series data of precipitation and water level. Through this, it is thought that it can be utilized as an initial study to determine the time of flood evacuation to prevent unnecessary evacuation and to ensure that evacuation can be carried out at an appropriate time.

  • Recently, due to global warming, it is easily exposed to various disasters such as fire, flood, and earthquake. In particular, large-scale disasters have continuously been occurring in crowded areas such as traditional markets, facilities for the elderly and children, and public facilities where various people stay. Purpose: This study aims to detect a fire occurred in crowded facilities early in the event to analyze and provide an optimal evacuation route using big data and advanced technology. Method: The researchers propose a new algorithm through context-aware 3D object model technology and A* algorithm optimization and propose a scenario-based optimal evacuation route selection technique. Result: Using the HPA* E algorithm, the evacuation simulation in the event of a fire was reproduced as a 3D model and the optimal evacuation route and evacuation time were calculated for each scenario. Conclusion: It is expected to reduce fatalities and injuries through the evacuation induction technique that enables evacuation of the building in the shortest path by analyzing in real-time via fire detection sensors that detects the temperature, flame, and smoke.
