The elderly population in Korea is constantly increasing. As the number of Long-Term Care hospitals increases, many fires have occurred in related facilities. In this facilities, due to the characteristics of the occupants, self-evacuation is difficult, resulting in a number of casualties. It is necessary to Life safety design that reflects the characteristics of the occupants of domestic long-term hospitals. The study attempted to suggest improvements to the standards of evacuation behavior model for occupants of domestic and overseas long-term care hospitals. As a result of the study, patients living in long-term hospitals have a problem that is difficult to evacuate on their own. It is judged that there is a need to present an evacuation behavior model database by setting evacuation priorities and evacuation plans. In addition, it is necessary to more the design factors that affect the evacuation model as well as the characteristics of the occupants of the long-term care hospital.

Fire safety management on any construction site should start with recognizing fire risks in the workplace, understanding the extent of the risks, and proper assessment of the controls necessary to reduce the risks. However, the most important step to prevent fire-related accidents on jobsites is the constant review and monitoring of processes and controls by all individuals involved. This study was conducted to analyze the effectiveness of using computer simulation as an addition to maps or floor plans in safety training and management. Simulex was used on a real project to model various egress routes and to identify potential problem areas of the evacuation strategy. This study highlights the efficacy of simulated emergency evacuation as a training tool that visually shows constantly altering means of egress.

This study also conducted T-test and Anova to find the different perceptions of the lightweight partition walls and the evacuation space, and the different perceptions of related laws according to the characteristics of the residents and managers. The findings and suggestions were as follows. Firstly, strengthening of the Senior Fire Safety Manager system to prevent the insolvency of fire safety management due to the affiliate. Secondly, implementing enhanced penalties in accordance with not implementing residents education, in order to prevent not smoothly delivering manager trained education to residents. Thirdly, adjusting hands-on training time according to the gender of the managers to supplement women's relatively low perceptions of lightweight partition. Fourthly, mandating evacuation guidance stickers on the evacuation space for residents to remove obstacles in the evacuation space. Finally, establishing regular residents education system in order to improve the awareness of the related laws for residents residing over 16th floors.

Although the school-age population is continuously decreasing, the number of people eligible for special education is increasing every year. Special schools, which are comprised entirely of students with special education needs, are vulnerable due to restrictions on evacuation in the event of a fire. However, the characteristics of special schools are not reflected in the plans related to firefighting and safety in special schools. In this study, essential items such as placement of helpers were selected through analysis of firefighting and school safety plans and collection of faculty and staff opinions. Afterwards, through analysis of experts' opinions, a basic fire evacuation scenario was presented that reflected the characteristics of special schools. We hope that this scenario will contribute to the development of customized fire evacuation scenarios for each special school in the future.

Recently, property and life loss is increasing internally and externally, due to fire spread in high-rise buildings which results from a variety of disasters like fire and terror. In this study, therefore, an evacuation simulation was performed to predict escape behaviors of occupants and assess escape safety in high-rise office buildings after setting up each scenario, as part of safety measures for high-rise buildings. Based on the results and data obtained, escape safety was assessed, finally. The results and suggestions of this study are as follows. Firstly, most of the present researches on high-rise building and multiple-use facilities are weighted towards qualitative perspectives. It is, therefore, considered that we have to establish concrete, practical, systematical and rational safety measures to minimize damages in dangerous situations, by analyzing security plans for high-rise buildings in depth and preparing for those situations from various angles. Secondly, setting up evacuation sections in security plans for high-rise buildings is an important factor which influences refuge. Thirdly, in relation to security plans for high-rise buildings, it is possible to reduce the entire time for escape, by setting up escape exits of each floor in consideration of a simultaneous evacuation situation.

Using elevators for emergency evacuation has been a controversial topic during the past few years. Generally, elevators are not allowed to be used in the event of a fire or emergency situations all around the world. However elevators assisted emergency evacuation procedures are considered and some of the plans are developed and accepted by the building management and local authorities after 9/11 WTC tragedy. The aim of this study is to quantify the benefit of elevator assisted emergency evacuation based on an actual super high-rise building design.

This study chiefly aims to clarify optimize evacuation circulation which can be applied to architectural planning through the analysis of educational facilities. On the planning phase, the evacuation circulation of buildings are defined through the zoning of plans and sections based on the functions and purposes. It is very important to consider efficient evacuation circulation under the circumstances of disasters such as fire and earthquake etc, and it is directly related with the lives of people in the educational facilities. This study tries to find out methods can be applied to architectural planning and architectural design through optimized circulation after the analysis and understanding of behavioral characteristics of human.

Accidents on offshore oil and gas platforms (OOGPs) usually cause serious fatalities and financial losses considering demanding environment platforms locate and complex topsides structure platforms own. Evacuation planning on platforms is usually challenging. The computational tool is a good choice to plan evacuation by emergency simulation. However, the complex structure of platforms and varied evacuation behaviors usually weaken the advantages of computational simulation. Therefore, this study developed a simulation model for OOGPs to evaluate different evacuation plans to improve evacuation performance by integrating building information modeling (BIM) and agent-based model (ABM). The developed model consists of four parts: evacuation model input, simulation environment modeling, agent definition, and simulation and comparison. Necessary platform information is extracted from BIM and then used to model simulation environment by integrating matrix model and network model. During agent definition, in addition to basic characteristics, environment sensing and dynamic escape path planning functions are also developed to improve simulation performance. An example OOGP BIM topsides with different emergent scenarios is used to illustrate the developed model. The results showed that the developed model can well simulate evacuation on OOGPs and improve evacuation performance. The developed model was also suggested to be applied to other industries such as the architecture, engineering, and construction industry.

Korea faces The 2014 Incheon Asian Games and 2018 Pyungchang Winter Olympics. It is imperative to hold a safe event for the economic benefits, enhancing Korea's image, social integration, national harmony and unity in order to be evaluated as a successful international event. Furthermore, since the international event tends to draw many spectators, the host country must be ready to accommodate a large number of injured people in the event of an accident or terror attack. As stadiums for international events are where a large number of spectators gather in, a large refuge is essential, when dangerous situations happen. In this study, evacuation simulation was conducted using three scenarios in order to predict escape behaviors of spectators during the large escape by destruction of safety systems of stadiums and assess escape safety. As the result, the following results and proposals were extracted. Firstly, it is considered that dangerous situations during the security of stadiums should be predicted in advance and concrete plans for a large refuge of spectators have to be established to minimize damage. Secondly, it was found that the reduction in evacuation exits has an important impact on evacuation in an emergency situation. It implies that securing escape exits are quite important. Thirdly, there were areas where spectators stayed, due to blocked escape exits, while they were dispersed and concentrated at once. It demonstrates that security plans considering properties of facilities are required to solve these problems.
