Escape distance and escape barrier are critical elements for the quantitative evaluation of escape safety. Through theoretical demonstration and modeling in precedent studies, they have been analyzed for their generality and applicability. To make more practical evaluation method, we should quantitatively analyze the influence of each barrier and escape condition on escape safety considering various barriers in escaping routes. In this study, to develop more accurate and applicable escape analysis model, we have focused on three research methods as below: First, we derived quantified function to predict various escape barriers in escaping routes by theoretical analyses of the escape barriers and conditions. Second, we substituted the derived quantified function for an evaluation tool of escape safety suggested by precedent studies. Third, we examined applicability and feasibility of the developed method by modeling with the consideration of the escape conditions and barriers.

This study investigates concept of escape room game and sorting story type based on 428 games at 141 escape room actually played. The classification were processed by Act 3 of Trottier, and as a result of the investigation, result shows three story types in offline room escape games. As for the types shown as, reason, condition and purpose of escape are guided before entering the room; a+b+c, purpose of escape is guided before entering the room but conditions for escape should be determined through play; a+b(c), and finally figure out the condition, purpose of the game during the play;(a+b+c).

This study represents a fundamental research for a passenger-ship escape guidance system that is a ship-borne agent, and it is for the support of escape decision-making by providing accurate maritime safety information in real time. We conducted a passenger escaping experiment on a training ship, SAEYUDAL, using the situation-aware escape guidance system, which has been developed for on-board application based on products for buildings. It is shown that the system contributes to the shortening of the escape duration and the dispersion of the escaping persons by generating and guiding the safe escape routes which dangerous areas are considered. From the experiment on ship's heeling condition, it is revealed that the heeling angle is linearly related to the escape duration. Therefore, this study shows that the shortening of the escape duration enables a safe and rapid mustering that is the most important process under emergency and appropriate incident responses to minimize loss of lives.

The purpose of this paper is to improve the evacuation stability of residents in apartment fire. For this purpose, the actual condition survey about the obstacles was conducted on 3,056 escape stairs in the 183 apartments. In addition, the questionnaire investigation was carried out a survey targeting the residents of apartments about their experience of fire safety education, perception on safety management of escape stairs, and perception on fire safety. As a result of investigation, we confirmed that the obstacles were formed in the 1,916 escape stairs among the 3,056 escape stairs of the 183 apartments (percent of barricades in escape stairs: 62.70%). Furthermore, it showed that fire safety education experience was found to be 83.10% of subject. The perception on safety management of the subjects in the escape step and the perception on fire safety were $3.84{\pm}0.75%$, and $3.49{\pm}0.61$, respectively. In the results, most of the subjects had a fire safety education and knew how to safety management the escape stairs but, the practice of the safety management action was low. Based on the results in the paper, the policy proposal is that the fire safety education is emphasized to change from the perception to action.

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.

In this study, we have survey of the actual smoke exhaust condition and improvement program in special escape stair. We have collected and analysed the survey view take 50 professional advice. Domestic a technical and legal standard is rated as compared with an advanced countries to $40{\sim}60%$. Hazard must be improved a security with the evacuation where the standard of present time is safe the reply with 64% to appear it was analyzed with the fact that the improvement which it follows hereupon is necessary.

It presented the approach method for the station braking noise present condition and a braking noise reduction plan escape of the KTX train. The research which it sees the technical ground it will be able to accomplish the station braking noise reduction of the KTX vehicle with base the questing matter where the escape one thing is big there is a possibility of doing.

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.

The present paper questionable matter and necessity of real estate information ethics, triangular position method etc. is an escape and for is. And currently the real estate information ethical violate action where becomes the problem the plan which raises an ethical level is an escape and for is. Preceding research led first of all and justice a real estate information ethics and necessity, scope, function and basic principle escape. Also at current law escape sent 'accidental incorrect reports', 'preservation of the list must erase', 'light plagiarism' and 'information is inappropriate managed' in the object of the real estate information ethics which excepts the illegal act. With the real estate relation specialty led interview together and currently actual condition real estate current price information where becomes the problem and article for sale information type nonly-ethical and also the cause analyzed together. This led and also the real estate information ethical raising plan did escape together.

In this paper, we present Emergency exit signs are installed to provide escape routes or ways in buildings like shopping malls, hospitals, industry, and government complex, etc. and various other places for safety purpose to aid people to escape easily during emergency situations. In case of an emergency situation like smoke, fire, bad lightings and crowded stamped condition at emergency situations, it's difficult for people to recognize the emergency exit signs and emergency doors to exit from the emergency building areas. This paper propose an automatic emergency exit sing recognition to find exit direction using a smart device. The proposed approach aims to develop an computer vision based smart phone application to detect emergency exit signs using the smart device camera and guide the direction to escape in the visible and audible output format. In this research, a CAMShift object tracking approach is used to detect the emergency exit sign and the direction information extracted using template matching method. The direction information of the exit sign is stored in a text format and then using text-to-speech the text synthesized to audible acoustic signal. The synthesized acoustic signal render on smart device speaker as an escape guide information to the user. This research result is analyzed and concluded from the views of visual elements selecting, EXIT appearance design and EXIT's placement in the building, which is very valuable and can be commonly referred in wayfinder system.
