Purpose: This study was conducted with the aim of presenting spatial planning directions for evacuation spaces based on an analysis of the performance of horizontal evacuation during the early stages of fire incidents in a geriatric hospital. Methods: Based on a review of previous studies, the research model was designed by establishing occupancy conditions, evacuation, and fire scenarios. The analysis model was developed by considering vulnerable areas in terms of evacuation movement and analyzing the results of evacuation performance. Furthermore, the study analyzed the improvement in evacuation performance by arranging refuge areas. Results: The results of the study are as follows. Firstly, vulnerability spots were identified in terms of evacuation performance by schematizing Required Safe Egress Time, Available Safe Egress Time, and their differences. Secondly, the Required Safe Egress Time in the adjacent public spaces along the escape routes of occupants was found to be higher compared to the Available Safe Egress Time. Thirdly, the results of the correlation analysis between the difference in Available Safe Egress Time and Required Safe Egress Time during the early stages of a fire, as well as their constituent factors, demonstrated that user congestion is a more significant factor in compromising evacuation safety than the physical changes in the fire condition. Fourthly, the analysis of evacuation time was conducted by designating refuge areas where occupants can evacuate within a sufficient timeframe. This led to a decrease in the Required Safe Egress Time. Implications: This study is expected to be used as data on the direction of evacuation space planning to improve the evacuation performance of Geriatric Hospital.

This study aims to clarify how commissioned welfare volunteers could play a role of evacuation assistance for people with special needs in case of flood disaster which occurred in Sayo-cho, Hyogo prefecture by Typhoon 9th in August, 2009. Both questionnaire research and interview was conducted to commissioned welfare volunteers. As a result we found that the delay of official evacuation council caused some confusion. As commissioned welfare volunteers had not got enough information on evacuation assistance from local government it was difficult to decide and initiate early evacuation against flood disaster. Development of collaboration with community manpower is inevitable for effective evacuation assistance on elderly and disabled people.

The purpose of this study is to present the possibility of adopting beacons to implement the fire evacuation guidance system in order to reduce the evacuation time for a fire in complex buildings. A beacon-based evacuation system can quickly detect a fire's origin, optimal path of evacuation involved with the exits and the location of evacuees using information collected by the proposed system. The assessment is conducted by integrating different scenario models including fire simulation. Based on the research result, beacon is an effective tool to warn potential hazards or to provide early detection and a safe escape.

Early evacuations reduce the damage caused by catastrophic events such as terrorism, tsunamis, heavy rains, landslides, and river floods. However, even when warnings are issued, people do not easily evacuate during these events. To shorten the evacuation time, initiative-evacuation and its executors, initiative evacuees, are crucial in inducing other evacuations. The initiative evacuees take the initiative in evacuating and call out to their surroundings. This paper proposes a fast method to induce initiative-evacuation based on social graphs. The candidates are determined in descending order of the number of links for each person. The proposed method was evaluated through simulations. The simulation results showed a significant reduction in evacuation time.

The purpose of this study is to investigate specific crowding areas resulted from diverse physical factors of multi-plex theaters in a fire evacuation, and more accurately predict the evacuation route of people. To achieve these purpose, the architectural characteristics of three multi-plex theaters in Jinju have been chosen, and the evacuation experiments through the computer simulation called Simulex were carried out for each on the these theaters. The conclusions from this study are as follows: (1) Crowding usually happens cross areas between theater inside and corridors, and Crowding rate depending on the number of cross areas. (2) It is necessary to design the escape routes being employed ordinary times. And the egress routes planning should be integrated into space programming at the early stage of building design.

맞벌이 부부가 계속 늘어나고 조기교육의 열풍 흐름에 따라 이제는 어린이집도 안전한 보육환경 개선과 보다 효율적이며 질적으로 우수한 서비스를 운영하고자 급속히 변화하고 있다. 건축물 내에서 화재나 재난 발생 시 가장 중요한 것은 재실자의 안전한 피난(evacuation)으로, 이를 위한 '안전한 피난로'의 확보는 최악의 위기상황에서 발생할 수 있는 여러 재난피해를 줄이는데 중요한 선결조건이다. 또한 이러한 재해약자의 피난을 성공적으로 수행하기 위해서는 환경적 요인뿐만 아니라, 피난자를 조력하는 보육교사의 안전의식 및 역할 등이 영유아들의 피난안전을 좌우하는 중요한 요소이며, 이에 따른 올바른 피난시설에 대한 지속적이고 반복적인 교육 훈련도 이루어 져야 한다. 본 연구에서는 어린이집 피난 관련 시설에 대한 보육교사 설문지법 등을 통하여 기존 설치되는 피난설비의 효율성을 검증하고 활용방안을 제시하고자 한다.

This paper studied on the performance variation depending on using period of ionization smoke detector. In korea, there were a lot of loss of lives and property because of fire. In many cases, an alarm equipment didn't operate though it was set up, so it causes the failure of early evacuation and fire suppression. Accordingly, an experiment on the change of ionization smoke detector in capacity performed with ionization smoke detector which is set up with fire objects.

In early 2011, the Fukushima nuclear power plant had greater damage due to earthquake in Japan, and the awareness of safety has increased. In particular, special response systems should be required to handle disaster situations in plant sites which are likely to occur for large disasters. In this study, a program is designed to set up optimum escape routes, by a smart phone application, when a disaster situation occurs. This program could get information of the cumulative damage from sensors and display the escape route of the smallest damage in real-time on the screen. Utilizing our application in real-time evacuation has advantage in reducing cumulative damage. The optimal evacuation route, focusing on horizontal path, is calculated based on getting the data of fire, detected radioactivity and hazardous gas. Thus, using our application provides information of optimal evacuation to people who even can not hear sensor alarms or do not know geography, without requiring additional costs except fixed sensors or server network deployment cost. As a result, being informed of real-time escape route, the user could behave rapidly with suitable response to individual situation resulting in improved evacuation than simply reacting to existing warning alarms.

최근 보육시설의 확충과 보육환경의 개선, 보육서비스 질 향상에 대한 사회적 욕구는 급속히 증가하고 있으며, 특히 화재 등으로부터 안전환경 확보가 범국가적 이슈로 대두되고 있다. 보육시설은 영유아 등 재실자의 대부분이 피난능력이 떨어지는 재해약자로 구성되어 건물 내 설치층수, 피난시설의 설치 적정성 등이 피난안전을 좌우하는 중요한 요소이다. 본 연구에서는 보육시설 설치현황, 국내외 관련 기준의 비교분석, 피난 관련 시설의 실태조사 등을 통하여 보육시설 피난안전성 측면에서의 문제점과 개선요소를 파악하였다. 그 결과 화재안전 관련 법규정의 체계화, 비상재해대비시설의 설치기준 및 관리에 대한 소방기관과의 연계, 스프링클러 등 보다 강화된 소방설비 설치규정의 개선, 화재위험시설과 동일 건물 내 설치금지 등이 필요한 것으로 분석되었다.
