본 논문은 2015년에 발생된 의정부 공동주택화재와 같이 화재발생시 초기 피난실패로 안타까운 인명피해 발생을 최소화하기 위하여 피난성능향상을 위한 주소형 비상방송시스템의 필요성에 관한 연구이다. 특히, 현대 건축물과 같이 복잡한 내부구조에서 발생되는 화재피해를 최소화하기 위해서는 정확한 화재위치를 재실자에게 경보하여 초기 피난방향 오류방지를 통해 효율적인 피난이 가능한 적응성 있는 비상방송시스템의 도입이 필요하다. 이에 본 연구에서는 기 개발된 주소형 시스템을 이용한 주소형 비상방송시스템을 설계 제작하고, 기존 재래식 비상방송시스템과의 성능비교실험을 실시하여 피난성능향상을 위한 주소형 비상방송시스템의 필요성을 확인하였다. 실험결과 주소형 비상방송시스템이 재래식 비상방송시스템보다 축소모형 피난성능실험에서는 최대 30.3%, 복도 피난성능실험에서는 최대 54.6% 이상 피난완료시간이 단축시킬 수 있는 것을 확인할 수 있었다.

Nowadays, the most of commercial buildings are build-out with complex architecture and decorated with more complicated interiors of buildings so establishing intelligible escape routes becomes an important case of fire or other emergency in a limited time. The commercial buildings are already equipped with multiple exit signs and these exit signs may create confusion and leads the people into different directions under emergency. This can jeopardize the emergency situation into a chaotic state, especially in a complex layout buildings. There are many research focused on implementing different approached to improve the exit sign system with better visual navigating effects, such as the use of laser beams, the combination of audio and video cues, etc. However the digital signage system based emergency exit sign management is one of the best solution to guide people under emergency situations to escape. This research paper, propose an intelligent evacuation route GUIDE that uses the combination centralized Wireless Sensor Networks (WSN) and digital signage for people safety and avoids dangers from emergency conditions. This proposed system applies WSN to detect the environment condition in the building and uses an evacuation algorithm to estimate the safe route to escape using the sensor information and then activates the signage system to display the safe evacuation route instruction GUIDE according to the location the signage system is installed. This paper presented the prototype of the proposed signage system and execution time to find the route with future research directions. The proposed system provides a natural intelligent evacuation route interface for self or remote operation in facility management to efficiently GUIDE people to the safe exit under emergency conditions.

본 논문에서는 긴급 재해 발생 시 피난 지원을 목적으로 하는 긴급피난지원시스템을 구축하기 위하여 실내에서 화재, 테러 등의 재해 발생 시 탈출 경로 탐색 알고리즘을 구현하였다. 긴급 상황이 발생하면 알고리즘은 가장 빨리 탈출할 수 있는 비상구로 탈출 경로를 안내해 준다. 알고리즘은 비상구나 비상구 이외의 지역의 인구 밀도와 연령별 가중치를 적용하여 탈출 경로를 계산한다. 본 시스템은 혼잡한 비상구를 우회하게 함으로써 비상구의 과중한 혼잡과 탈출 경로 상의 혼잡을 감소시키면서 재해 발생 지역을 우회하여 탈출하도록 돕는다.

This study uses Pathfinder software to simulate and analyze the safe evacuation of university dormitory occupants. Fire safety issues in densely populated dormitory buildings are gaining increasing attention, and improving emergency evacuation efficiency is crucial for reducing the harm caused by fire incidents. The study focuses on a student dormitory building in a university, simulating different evacuation scenarios and analyzing the impact of factors such as evacuation routes, personnel distribution, exit width, and stair width on evacuation time. Based on the actual dormitory conditions, parameters such as gender ratio, height range, shoulder width, and walking speed of the occupants were set, and evacuation times in various scenarios were compared.The simulation results show that proper planning of evacuation routes and increasing stair width significantly reduced evacuation times. The study recommends that universities establish systematic emergency response plans, conduct regular evacuation drills, optimize student dormitory layouts, and consider increasing stair width in dormitory building designs to improve evacuation efficiency and safety.

Emergencies and disasters can happen any time without any warning, and things can change and escalate very quickly, and often it is swift and decisive actions that make all the difference. It is a responsibility of the building facility management to ensure that a proven evacuation plan in place to cover various worst scenario to handled automatically inside the facility. To mapping out optimal safe escape routes is a straightforward undertaking, but does not necessarily guarantee residents the highest level of protection. The emergency evacuation navigation approach is a state-of-the-art that designed to evacuate human livings during an emergencies based on real-time decisions using live sensory data with pre-defined optimum path finding algorithm. The poor decision on causalities and guidance may apparently end the evacuation process and cannot then be remedied. This paper propose a cloud connected emergency evacuation system model to react dynamically to changes in the environment in emergency for safest emergency evacuation using IoT based emergency exit sign system. In the previous researches shows that the performance of optimal routing algorithms for evacuation purposes are more sensitive to the initial distribution of evacuees, the occupancy levels, and the type and level of emergency situations. The heuristic-based evacuees routing algorithms have a problem with the choice of certain parameters which causes evacuation process in real-time. Therefore, this paper proposes an evacuee routing algorithm that optimizes evacuation by making using high computational power of cloud servers. The proposed algorithm is evaluated via a cloud-based simulator with different "simulated casualties" are then re-routed using a Dijkstra's algorithm to obtain new safe emergency evacuation paths against guiding evacuees with a predetermined routing algorithm for them to emergency exits. The performance of proposed approach can be iterated as long as corrective action is still possible and give safe evacuation paths and dynamically configure the emergency exit signs to react for real-time instantaneous safe evacuation guidance.

본 연구에서는 구미시 일부지역을 대상으로 소개(疏開, 혹은 대피) 계획(evacuation planning)수립 기초연구를 위해 가능한 한 실제 네트워크 및 교통특성 자료를 기반으로 미시적 교통시뮬레이션을 이용하여 대안별 특성을 분석하였다. 긴급 상황이 발생했을 경우를 가정한 시뮬레이션을 통해 기존 교통신호 체계를 그대로 유지하는 경우에서의 소개시간과 본 연구에서 제안한 차로기반 경로유도(lane-based routing) 방식을 비교한 결과, 긴급 상황이 발생했을 시 기존 신호체계를 그대로 유지하는 경우에 있어 소개명령의 차이는 모든 차량을 소개시키는데 거의 영향을 미치지 않는 것으로 나타났다. 그에 비해 본 연구에서 제시한 차로기반 경로유도 방식의 경우 기존 방식에 비해 소개시간과 총 통행시간에서 각각 28~54%와 82~90%의 단축효과가 있음을 확인하였으며, 특히 소개시간을 짧게 해야 하는 급박한 상황이 발생했을 때 소개를 위한 시간단축을 확인하였다.

The purpose of this study is to provide the school planning factors as emergency shelter after disaster. The school functions as the evacuation space areas could be classified into the evacuation center, education maintenance, and dwelling. Among these functions, the scopes of our study are limited to the functions of evacuation center and education maintenance. To carry out this purpose, we were comparative analyzed the shelter space problems of Korea and Japan's survey in the existing literatures. In results of our study, the evacuation center's functions are difficult to depending on the disaster types, such as the earthquake, tornado, and hurricane. On the other hand, the education maintenance functions are difficult to deepening on the victims occupied times in the school as emergency shelters. Based on these findings, the Korea school planning as the emergency shelters are desired to reflect that the evacuation's functions based on the disaster type of the damage from storms, and the education maintenance's functions based on the victim's occupied times in school for their safety.
