Purpose: This study aimed to present an analysis model evaluating evacuation performance considering patient types and procedural evacuation in the medical facility. The user group of the medical facility, including users challenged in evacuation behavior, entails the risk of many casualties. Therefore, it is necessary to plan an evacuation procedure that considers the evacuation characteristics of users. Methods: Through the review of precedent studies, the evacuation procedure of the medical facility, the classification of patient types, and the evacuation procedure was set as conditions and variables for the analysis. The result caused by a variety of conditions and variables were explored. Results: 1) The total evacuation completion time and congestion time were shortened at the procedural evacuation. Moreover, it derived many users from evacuating at the initial phase. 2) The proposed model can provide a basis for proposing a space planning direction that considers the possibility of not carrying out the evacuation plan. 3) It supports safe evacuation by identifying variables that reduce overcrowding by comparing the congestion time of overcrowded spaces. 4) The analysis model can identify the overcrowded space through the evacuation route and suggest the basis for architectural improvements that reduce overcrowding. Implications: The study results can be used to analyze the performance of evacuation procedures and support the establishment of evacuation procedures and building plans for safe evacuation for medical facilities.

This study explored the fact that libraries can be used as evacuation facilities, suggesting that existing libraries built not only strengthen their role and function as evacuation facilities but also need to be constructed or remodeled to meet the criteria for designation and operation of evacuation facilities. The use of closed schools was proposed to pursue economic efficiency and regional effects in building or remodeling, and the status of the evacuation facilities and closed school in Chungju was evaluated to check the effectiveness of these proposals, and closed school was assessed based on the capacity of the shelter. The three main points of discussion in this paper are as follows: ① Reconfirm what functions and roles the library are performing as an evacuation facility, and explore the advantages of using the library as an evacuation facility is used as an evacuation facility. ② Review and discuss the synergy by the role of the library and the closed schools. ③ Examine and discuss the synergy between these roles of the library and the closed school.

Recently, Korea is constantly increasing its elderly care hospitals, and requires establishment of general evacuation plan considering old people's behavioral characteristics and physical states in emergency situations such as fire, and etc. In addition, because most of the facility users are patients under serious dementia and stroke, they feel difficulty evacuating by themselves, with differing evacuation time according to each walking status (bed, wheel chair, and various supplementary instruments), which is why it makes it difficult to have them all evacuate. This paper, in order to suggest data reference for designing on the basis of functionality, used various collected data utilizing Simulex to measure evacuation time through the model of elderly care hospital, a medical facility. During the study, several problems were found.

As environmental pollution becomes serious, natural disasters are frequent and damage is increasing. Also, due to population overcrowding, social disasters are frequent, and it is difficult to predict due to the variety of area, extent, and damage. As the disasters have diversified and the scale of the damage has increased, the scale of evacuees and the period of evacuation have diversified. Should be provide facilities that will be protected from second damages to victims who have lost their homes quickly. It supports a prefabricated house, but it is difficult to supply it. In this study, the ultimate goal is to plan an outdoor temporary housing facility that can supply quickly when the capacity of the evacuation facility is insufficient or the evacuation facility is insufficient.

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 analyzes the effects of personal lockers, drinking fountains, and all-in-one shutters (hereinafter referred to as "corridor walking obstacles") on evacuation safety to suggest the necessity of operating a more effective educational facility safety certification system. To achieve this purpose, the five-story high school building with the obstacles installed in the corridor has been chosen, and evacuation tests through the Pathfinder Simulation Program have been carried out. When the evacuation exit is designated in the current state, where the students are placed on the 2nd, 3rd, and 4th floors and the corridor walking obstacles are applied as a variable, the required safe egress time (RSET) is 322 seconds. This can lead to dangerous results in the event of a disaster by exceeding the available safe egress time (ASET) standard of 240 seconds by 82 seconds. When students are placed on the 1st, 2nd, and 3rd floors under the same conditions, the RSET is 214.5 seconds, 25.5 seconds lower than the ASET standard, indicating that it is effective in reducing the impact of walking obstacles on evacuation time. The safety management plan for walking obstacles in the corridors is discussed, considering the special characteristics of the school corridors. The results of this study can be used as the necessary data for optimizing evacuation routes in corridors and creating a safe, educational environment.
