This paper describes a study to determine proper escape way interval for the design phase of single bored double track tunnel. Among many methods which determine escape way interval, we choose a QRA(Quantitative Risk Analysis) method. But a different method must be chosen differ from other country because of special design situation of Korea. So, it is necessary to develop a method which considers a special design condition of Korea. Because fire accidents of railway tunnel are a rare event, simulated situation can be produced by CFD simulation and evacuation analysis simulation. However, it is generally difficult to estimate of fatalities from these methods, so a concept of FED is introduced to estimate of fatalities. Quantification process provides effective results for practical design stage and the result were employed in design.

All passenger ships aboard more than 36 passengers are to be able to easily find escape routes when the escape way by fire with flame spread were onboard vessel (incl. Ferry, Passenger, Ro-pax, Inland Ferry) It should be impossible by ordinary emergency lights. The international Maritime Organization (IMO) gives special requirement for luminescent evaluation onboard test procedure and applicable location of low location lighting. In order to maintain the residual light source for a certain time in the low location lighting with a strip-shaped light source, the light source material must be sufficiently exposed to the light due to the proper placement of the escape route. The lighting arrangement influence how maintain low location lighting strip luminescent which measured onboard in connection with what elements are mainly sustain luminescent.

The purpose of this study is to examine that the escape stair of high-rise buildings has to be designed as a left-handed stair(a stair being designed to turn left whicle we go down the ground floor) judging from fire-safety point of view. Most of Korean people are right-handers. In case of right-handers it was found that the occupant's escape speed using a left-handed stair is more convenient and fast than of a right-handed stair(a stair being designed to turn right while we go down the ground floor). But most of the escape stair of high-rise buildings in Korea was designed as a right-handed stair. The fire code therefore should be provided that the escape stair of high-rise buildings should be a left-handed stair.

Owing to increase of the large-scaled, high-raised and complexed building construction, the escape design of the building became very important issue to insure the safety of occupant. Specially, it is demanded to have building escape regulation considering for inconvenient movers such as disables elders pregnant women. However, building regulations for inconvenient movers are divided into "Regulation of Escape and Fire-prevention of Building" and "Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information". But, for the escape security of inconvenient movers, the connection of each regulation are necessary. So this study suggested the improvement direction of the building escape regulation considering inconvenient movers through the compared analysis on the "Regulation of Escape and Fire-prevention of Building" and "Act on the Promotion and Guarantee of Access for the Disabled, the Aged and Pregnant Women to Facilities and Information".

With the increase of apartments and expansion of balcony areas, fire safety issues are becoming more important. Many researchers have conducted a lot of researches to reduce vertical flame spread in the balcony when an apartment unit is in fire. However, there have rarely been studies to use balcony area as a space for fire escape and evacuation. The study aims to examine the conditions of balcony use in apartments in order to find out prevention elements from fire escape and evacuation, and to investigate residents' satisfaction with balcony. For this study, questionnaires were collected from apartment residents and workers of architectural planning and construction companies. The findings show as follows: first, the balcony is generally used as a storage in each apartment unit nowadays. Second, when fire breaks out, many storage items could disturb residents' safe escape by blocking escape route, and easily promote to spread flame vertically in the balcony.

As virtual reality drew attention, VR room escape games were based on the most popular and successful VR content. This study was based on the survey results of citizens who experienced actual VR room escape and field-type room escape. It clarifies the parts that can be implemented and the parts that have technical limitations. And the factors that can increase the immersion of VR room escape games are analyzed. It is hoped that the significance of the research can contribute to the production of more advanced VR escape games and further VR contents.

The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.

The purpose of this paper is to present refernce data to be considered in designing for the fire safety of high-rise office buildings. This paper deals with the characteristics of high-rise office buildings in the fire safety aspects, the basic principles for the fire safety of high-rise office building design, and this study is focused particularly on the location of the escape route of core plan for fire safety in high-rise office buildings.

There have been the current controversy over effectiveness of the pressurized smoke control systems, which are installed within escape shaft to provide 'smoke-free' access for escaping peoples. Therefore, many effective measures were given in this paper by means of the production of a design guide for various types of escape routes used in domestic buildings. The solutions were established on basis of both an investigating current door closing device application in existing facilities and global standardization for pressurized smoke control system, especially in British Standard. Finally, the design guidance for open door air velocity with introduction to three door protection clauses was presented on the basis of consideration of the safety and economical factor,

In this parer, we design the artificial intelligent direction escape light control system to improve/complete the defects of the existing fire fighting system, and sketch an optimum escape guide algorithm for its implementation. It intends to minimize human casualties and injuries by calculating/predicting moving line of the optimum emergency escape, by means of interlocking the sensor and the reception group and analyzing the data of the combustion point and the smoke movement. The optimum escape algorithm is designed by FLOYD algorithm which calculates the shortest distance. It consists of the measuring method which calculates the shortest distance by using hazardous factors for each condition in danger which is judged by the sensor installed in each area.
