Growing attention of a society to protecting weak people leads an increase of various social welfare facilities. Therefore, safety of the occupants at emergency situations, such as fire, must be considered as an important factor during the design and operation of those facilities. In this paper an exploratory study is carried out on a method quantitatively assessing the human evacuation safety of social welfare facilities. A evacuation simulation method, being routinely used in the evacuation analysis of passenger ships deriving 'Evacuability' as a quantity of safety, is applied to assess the human safety of a facility for single-moms. Based on the simulation results, the main factors that must be considered while carrying out the evacuation simulation for the human safety assessment of the facility are investigated.

Lifts are used as an essential means of transportation within the building in an emergency situation, when used as a means of escape, so expect a lot of research has been conducted high effect. Number of stories in the Seoul-rise building guidelines underground 7th floor, 53 ground floor, floor area $6,800m^2$, floor area $127,050m^2$, use is cultural and convention facilities and sales facilities, business facilities and accommodation (hotel), the construction of public housing (apartments) hagieneun not efficient to install elevators for evacuation mothada was determined separately in designing the lift is designed according to the standards of passenger lifts installed under a judgment as to use for evacuation. However, this does not include detailed design guidelines so far.[1] We propose the Evacuee Guidance of Elevator System that can be used as entering air equipment, sprinkler and smart phone evacuation system.

The use of emergency escape breathing devices (EEBD) is strongly required to protect against toxic gas or flooding caused by ship fires or accidents. Recently developed domestic EEBD products only satisfy the basic performance requirements, but no wear fit and activity performance evaluation has been done for real usage. In this study, the global level test requirements for wear comfort and activity of EEBDs were developed and the open and closed type of domestic EEBD products were evaluated. Poor visibility, longer wear time, breathing resistance, and hose obstruction in an open type and canister obstruction, weight unbalance, and an invisible black breathing bag in the closed type EEBD were estimated to be the main problems that need to be improved.

해양구조물에서 헬리콥터는 주로 인력을 수송하지만 비상상황 발생 시 탈출수단 또는 수색 구조수단으로 이용되고 있으며, 자원을 찾아 깊고 먼 바다로 이동하는 해양구조물의 인력을 수송하기에 헬리콥터는 가장 빠르고 안전한 수단이지만 해상으로 추락과 같은 사고는 발생할 수 있다. 헬리콥터의 수중 추락 시 생존율을 높이기 위하여 헬리콥터 자체의 안전설비와 운용방식을 발전시키고 탑승자들에게 사전 브리핑을 실시하고 수중탈출 훈련을 실시하였다. 본 논문에서는 헬리콥터의 해상 추락 사고를 분석하고 탑승자의 생존율을 높이기 위한 헬리콥터의 안전설비 및 운용방식과 수중 추락 시 탑승자의 탈출요령에 대한 훈련에 대하여 소개한다.

In this paper, advanced evacuation analysis simulation on a passenger ship is performed. Velocity based model has been implemented and used to calculate the movement of the individual passengers under the evacuation situation. The age and gender of each passenger are considered as the factors of walking speed. Flocking algorithm is applied for the passenger's group behavior. Penalty walking velocity is introduced to avoid collision between the passengers and obstacles, and to prevent the position overlap among passengers. Application of flocking algorithm and penalty walking velocity to evacuation simulation is verified through implementation of the 11 test problems in IMO (International Maritime Organization) MSC (Maritime Safety Committee) Circulation 1238.

In the wartime, aircraft carrying out a mission to strike the enemy deep in the depth are exposed to the risk of being shoot down. As a key combat force in mordern warfare, it takes a lot of time, effot and national budget to train military flight personnel who operate high-tech weapon systems. Therefore, this study studied the path problem of predicting the route of emergency escape from enemy territory to the target point to avoid obstacles, and through this, the possibility of safe recovery of emergency escape military flight personnel was increased. based problem, transforming the problem into a TSP, VRP, and Dijkstra algorithm, and approaching it with an optimization technique. However, if this problem is approached in a network problem, it is difficult to reflect the dynamic factors and uncertainties of the battlefield environment that military flight personnel in distress will face. So, MDP suitable for modeling dynamic environments was applied and studied. In addition, GIS was used to obtain topographic information data, and in the process of designing the reward structure of MDP, topographic information was reflected in more detail so that the model could be more realistic than previous studies. In this study, value iteration algorithms and deterministic methods were used to derive a path that allows the military flight personnel in distress to move to the shortest distance while making the most of the topographical advantages. In addition, it was intended to add the reality of the model by adding actual topographic information and obstacles that the military flight personnel in distress can meet in the process of escape and escape. Through this, it was possible to predict through which route the military flight personnel would escape and escape in the actual situation. The model presented in this study can be applied to various operational situations through redesign of the reward structure. In actual situations, decision support based on scientific techniques that reflect various factors in predicting the escape route of the military flight personnel in distress and conducting combat search and rescue operations will be possible.

This paper presents simulations of advance evacuation analysis using a cellular automata model for passenger behavior in an emergency of passenger ship. The proposed cellular automata model divides the space in a uniform grid called "cell." Each passenger is located in a cell and moves to another cell according to a set of local rules assumed to be associated with the individual and crowd behaviors of the passengers. To verify the usefulness of the proposed cellular automata model, 11 tests, all of which are specified in International Maritime Organization Maritime Safety Committee/ Circulation 1238 (IMO MSC/Circ. 1238), were implemented, and it was confirmed that all the requirements of these tests had been met.

본 논문에서는 초중등학교의 조회 및 실내 집체 교육은 내용과 수준에 따라 학년별로 서로 다른 내용의 방송을 동시에 실시할 필요성이 요구되고 있다. 그러나 현재 사용 중인 방송 설비는 일방적으로 같은 내용의 방송을 전달하고 있고, 서로 다른 내용의 방송을 위하여 별도의 라인을 설비해야하는 번거로움과 비용부담을 안고 있다. 또한, 큰 건물의 재난 방송 시스템도 장소와 위치에 따라 서로 다른 내용의 방송을 동시에 실시해야 하는 필요성이 제기되고 있다. 즉, 위치에 따라 비상탈출 안내 방송을 실시하고 상황변화에 따라 장소에 맞는 방송을 전달하기 위한 시스템이 필요하다. 따라서 본 논문에서는 인터넷 망을 이용하여 미리 계획된 스케줄에 따라 동시에 청취자에 맞는 맞춤형 방송을 실시할 수 있는 인터넷 스케줄링 방송 시스템의 임베디드 시스템을 개발한다.

항공기 추락 시 충돌충격단계에서 사상자가 가장 많이 발생하는 것으로 나타나고 있다. 대부분의 경우, 승객들은 두부손상으로 의식을 잃게 되어 비상탈출에 실패하여 사망에 이르게 된다. 이에 대한 대응책으로 항공기 제작사들은 내구성이 강화된 항공기 좌석을 설계 및 제작하여 설치하고 있다. 객실에서는 승객들이 충격방지자세를 취함으로써 부상을 최소화할 수 있다. 승객들에 대한 충격방지자세 안내는 모든 항공사가 시간적 여유가 있는 비상상황에서만 객실승무원이 안내방송과 함께 시범을 보이도록 절차가 수립되어 있다. 그러나 갑작스런 사고의 경우 승객들은 충격방지자세에 대한 정보를 전달받지 못한 상태에서 사상의 위험에 직면하게 된다. 본 논문은 SHEL 모델을 적용하여 승객과 사상자발생 환경, 승객과 충격방지를 위한 안전절차, 승객과 승객안전정보 전달매체, 승객과 객실승무원등의 상호작용에 내재된 위해요소를 체계적으로 규명하고 객실안전에 대한 법규 및 절차 등의 개정을 제시함으써, 항공기사고로 인한 사상자 발생에 대한 근본적인 대안을 제시하여 항공안전 증진에 기여하고자 한다.
