As part of the Fire Evacuation Service scenario using mobile applications, this study aims to find the appropriate colors to be used in the interface of the application and to define and apply colors that can positively and reliably affect human unstable psychology in the course of evacuating the room in case of fire. In the situation of fire, proper design and placement of the colored escape guidance interface is important, taking into account the psychology of the occupants. However, literature and previous research have shown that colors used to induce evacuation are not suitable for effective evacuation in case of fire. In this study, the purpose of the study was to provide a color that would provide psychological stability in the event of a evacuation in consideration of the psychological issues of those who are still in need of shelter, and to use it to help induce an efficient evacuation in the event of a disaster. Using the image evaluation method, the form and color of images have been derived through frequency analysis to a number of unspecified people, and the main and secondary colors of images were analyzed through KSCA color analysis. Finally, the final application color was constructed through mutual verification between the results by comparing and analyzing the colors obtained through the image evaluation analysis results and the KSCA color analysis results. The results of the study showed that the green line can help stabilize the human mind through comparative analysis with prior research. Therefore, the main color for guiding calm and calm applications in case of fire escape is proposed in the green line. In this study, the experiment with image evaluation cannot accurately measure the effect of factors on color among complex factors. A subsequent study of this will help quantify images if it allows the subject matter of color and image to be defined to some extent through factor analysis.

Through the use and development of underground spaces, subways have become a representative means of transportation in the city center. Due to the extension of subway lines and the increase in the number of subway users, there is a risk that safety for evacuating human lives in case of fire will not be secured. Therefore, this study tried to identify citizens' perceptions of evacuation facilities through questionnaires and find alternatives. An online survey of 115 subway passengers was conducted to learn about citizens' awareness of subway evacuation facilities. As a result of the survey, awareness of evacuation facilities was high in the order of guidance lights, life-saving devices, emergency lights and portable lights, special evacuation stairs, and evacuation stairs. In addition, the majority of the respondents said they were not well aware of evacuation facilities, and people's indifference was the most common cause. As a solution to the lack of awareness, responses to active advertising and promotion, education and experience activities were the highest.

When the fire in the high-rise building was not extinguished in its early stage and propagated over its origin, safe egress becomes one of the most important factor to minimize the casualties. Recently fire protection for high-rise building has been reinforced after experiencing the series of disastrous fires. But, we still find many high-rise buildings do not comply with those reinforcement. And also there is a possibility of failure of reinforced fire protection system. Under these situation safe egress guide would be the final layer of protection. In this study existing egress methods were identified and evaluated. According the result of study, priority in egress should be given to the tenants on the floor of fire origin and floors exposed to the risk of fire. Then, the rest of the tenants can be evacuated simultaneously. Floors exposed in fire risk shall be determined by fire tests and/or fire simulations. But, the result of fire monitoring shall override preliminary estimations. Egress time for each algorithm was estimated by egress simulation and the result was compared. There was a little difference in egress time between total egress and phased egress, and a big difference between using stairs only and using elevators and stairs together. to a constant thickness between layers constituting a firefighter's protective clothing should be considered in the future.

Most of the sign systems involved in evacuation are not useful in seismic situations where people have to evacuate with their heads bowed, given that they are at the top of the wall. Based on the analysis and understanding of seismic evacuation situations, this study proposes a sign system as a measure for rapid seismic evacuation. First, understand the seismic situation based on the video analysis of the earthquake evacuation situation. Second, the need for a sign system to help secure evacuation in earthquake situations was derived. Third, the on-site survey examined the suitability of the Sine system installed in Korea as an escape facility for the earthquake evacuation situation. Based on the video analysis and on-site survey, it was concluded that the installation of escape guidance lamps alone could not induce rapid evacuation in the earthquake situation. In this study, a sign system is proposed to help the use of doors by installing a sign system near an emergency exit light.

본 연구에서는 시각장애인 복지관에서 시각 장애인 이동형태에 따른 속도를 대피 실험을 하여 비 장애인과의 비교 분석 실험을 통해 시각 장애인 시설 피난 안전에 관한 기준을 제시하고자 한다. 시각장애인 들은 정상인들과 달리 비해 소리와 감각으로 판단하기 때문에 이동속도가 느리고 피난유도가 어렵기 때문에 대피시의 피난 성공을 위한 피난 안전에 관한 기준 마련을 위한 기초데이터를 제공한다.

This study is intended to examine the effect of the evacuation guidance that used phosphorescent material for stairs in the event of smoke and failure of both the power to the lighting and illuminated sign. To achieve the purpose, the test stairs was established and 35 students(1st 20, 2nd 15) were examined the visibility, the convenience and the comfort of going up and down of stairs. The results of this study are as follows; The evacuation from stairs showed that the stair nosing and landing used phosphorescent material for was very effective in dark conditions(0 lux) because of the high visibility of stair nosing and the convenience and the comfort of going up and down of stairs. The phosphorescent material located on the stair nosing and stair landing will aid in evacuation from stairs in the event of failure of both the power to the lightings and illuminated sign.

This study analyzes the efficient floor layout plan of classrooms for securing evacuation stability in school in case of fire by using the Pathfinder simulation program. Efficient evacuation methods and safety were evaluated by analyzing REST (Required Safe Egress Time) according to the allocation of personnel by floor targeting a high school 5-story building equipped with a ramp and stairs. The current status of personnel assignments exceeded the Required Safe Egress Time(RSET), resulting in a problem with evacuation safety. When students were placed on the 3rd, 4th, and 5th floors, the result was that the time exceeded RSET the most. When students were placed on the 1st, 2nd, and 3rd floors, the result was that they completed evacuation in the shortest time, less than RSET. In the current state, when evacuation was guided by designating an evacuation exit depending on the location, the result of shortening RSET was obtained. As a result, it is effective to put the students on the lower floors when placing students in high-rise school buildings in terms of evacuation safety, and in the preliminary training, it is required to designate evacuation exits so that they can use the nearest exit for each location in case of a fire. As a future research project, additional research is needed on the RSET when a fire occurs in a specific location according to whether the automatic fire door at that location is opened or closed.
