In this research, we determine the proper number of entrances in the evacuation facilities for civil and military personnel. The current standards on the emergency evacuation facility only sets the number of possible evacuees and the according architectural floor area since the evacuation have been completed. However, other than static standards such as the floor area, there is needs to consider the dynamic standards along with allowable evacuation time such as the number of entrance, staircases and so on. Therefore, we need to consider the number of entrances and their location in order to account for the allowed evacuation time of particular number of people in a set area. The outcome could be contributed to the standards which should contain the dynamic conditions associated with evacuation.

Background: Korea Atomic Energy Research Institute (KAERI) operates several nuclear research facilities licensed by Nuclear Safety and Security Commission (NSSC). The emergency preparedness requirements, GSR Part 7, by International Atomic Energy Agency (IAEA) request protection strategy based on the hazard assessment that is not applied in Korea. Materials and Methods: In developing the protection strategy, it is important to consider an accident scenario and its consequence. KAERI has tried the hazard assessment based on a hypothesis accident scenario for the major nuclear facilities. During the assessment, the safety analysis report of the related facilities was reviewed, the simulation using MELCOR, MACCS2 code was implemented based on a considered accident scenario of each facility, and the international guidance was considered. Results and Discussion: The results of the optimized protective actions were 300 m evacuation and 800 m sheltering for the High-Flux Advanced Neutron Application Reactor (HANARO), the evacuation to radius 50 m, the sheltering 400 m for post-irradiation examination facility (PIEF), 100 m evacuation or sheltering for HANARO fuel fabrication plant (HFFP) facility. Conclusion: The results of the optimized protective actions and its distances for the KAERI facilities for the maximum postulated accidents were considered in establishing the emergency plan and procedures and implementing an emergency exercise for the KAERI facilities.

This study compared evacuation effectiveness between the conventional school auditorium plan and a suggested hypothetical plan that was generated by a mathematical model, which is commonly applied in the field of industrial engineering. Recent school buildings became much more complicated in floor planning due to new social needs and modern curriculum than the old days. Nevertheless, architect's approach to floor composition in terms of fire emergency evacuation planning, still has no relation to optimized effective but relies more on an conventional school planning. Therefore, since school buildings are much more likely to be exposed to any fire related events than any other building types, emergency exit effectiveness based on spatial composition has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type(node) per floor and the minimum physical distance between spatial types(arc), can propose the most optimized spatial layout per floor regarding emergency evacuation event. Consequently, this study evaluated school's fire exit effectiveness focusing on auditorium area with the scientific tool and suggested the most reliable spatial layout regarding possibile emergency evacuation event.

This study compared evacuation effectiveness between the conventional school floor plan and a suggested hypothetical floor plan that was generated by a mathematical model that is commonly applied in the field of industrial engineering. Recent school buildings became much more complicated in floor planning due to the new educational system and modern curriculum than the old days. Nevertheless, architect's approach to floor composition in terms of fire emergency evacuation planning, still has no relation to optimized effective but relies more on a conventional school planning. Therefore, since elementary school buildings are much more likely to be exposed to any fire related events than middle school or high-school, emergency exit effectiveness based on spatial composition has to be seriously evaluated with a scientific method. The algorithm, which acquires the number of persons in each spatial type (node) per floor and the minimum physical distance between spatial types (arc), can propose the most optimized spatial compositing per floor regarding emergency evacuation event. Consequently, this study evaluated elementary school's fire exit effectiveness with the scientific tool and suggested the most reliable spatial composition per floor regarding possibile emergency evacuation event.

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.

This study developed an algorithm to predict the most efficient evacuation protocol in an elementary school that has an irregular type of architectural planning. The assumption of this study takes a stand point that today's elementary schools are designed in unusual and irregular floor type and, therefore, past architect's knowledge regarding efficient evacuation will no longer effective to save lives. In this regard, this study applied an algorithm that is especially designed to find appropriate locations in general in the field of industrial engineering, which has been proven for many decades. Furthermore, this study not only adapted an engineering model but also conversed to examine spatial relationship and added the concept of group evacuation, which will delay the whole evacuation process, in the tested algorithm to make it more architectural. Consequently, this study compared its outcome with an existing elementary school and questioned its effectiveness in evacuation process based on the algorithm.

본 연구에서는 비상대피시설의 출입구 개수 산정의 적정성을 평가하고자 하였다. 현행 민 관 군 대피시설의 기준은 대피 인원이 대피를 완료한 상황을 가정하여 적정 건축면적을 보유하도록 하는 정태적 기준만을 제시하고 있다. 그러나 실제 대피상황을 감안한다면 건축면적과 같은 정태적 기준보다는 출입구 개수, 대피인원, 대피시간 등과 같은 동태적 기준을 동시에 고려할 필요가 있다. 이를 위해 동태적 기준이 대피시간에 어떠한 영향을 주는지 대피 시뮬레이션을 통해 매개변수 연구와 회귀분석을 실시하였다. 그 결과를 대피시간에 대한 추정 모델을 개발하고 대피인원대비 적정 출입구 개수를 제시하였다.
