It is sharply decreasing from several hundred[lx] to 1.0[lx] when it turn on the emergency lamps. The sharply decreasing illuminance makes peoples to have dark adaptation for long time. And they were with fear and confused. It also causes secondary accidents by people who take a mistake. This paper studied the combination style emergency lighting fixture to improve a problem of dark adaptations. But it was made an assumption that same conditions of battery capacity and a number of emergency lamps.

This study intends to analyze the accessibility to the evacuation shelters according to pedestrian characteristics for Shinpo-district and Haewoon district, Masan Happo-gu, Changwon, designated as Disaster Risk Districts(Typhoon and Storm Surge Risk Zones) due to the typhoon and surge disasters of the past such as Typhoon RUSA or MAEMI. Evacuation speed was analyzed by dividing the types of evacuees into children, general adults, and the aged people by considering physical conditions. In the case of Haewoon district, currently designated evacuation shelters appeared to be appropriate. But in the case of Sinpo district, over 50% of designated Disaster Risk Districts appeared to be evacuation-vulnerable zones in the case of the aged. Therefore, three additional shelters were designated to complement these problems. The results reveal that the problems about the evacuation-vulnerable zones in the case of the existing designated shelters, appeared to be improved. It is expected that the results, obtained in this study will be utilized to establish the complementary measures to analyze the evacuation risk and solve the problems.

현대에는 건물이 대형화, 고층화되어짐에 따라 많은 재실자들을 수용함으로써 대형 재난의 잠재적인 가능성을 가지게 된다. 더욱이 건물의 미적인 면과 효율성이 강조됨에 따라 재난시 재실자의 대피에 영향을 주는 통로와 사무 시설 배치등과 같은 방과 건물구조의 용도 변경이 잦아지게 되었다. 그러나 안전적인 측면에서 특히 재실자의 대피는 피난 법규의 요구이외에는 설계시 특히 건물 내부의 용도 변경시 피난의 상황은 중요하게 고려되어지지 않고 있는 실정이다. 이에는 설계자나 건물 관리인에게 있어서 안전의 개념의식이 미비한 점도 있지만 대피시의 상황을 예측할 수 있는 효율적인 프로그램의 개발이 적절히 이루어지지 않았기 때문이라고 생각되어 진다. 이에 본 논문은 동일 건물 구조하에서 재실자들의 대피 상황을 프로그램을 통하여 미리 제시함으로서 설계 및 건물구조 변경시 건물 구조의 효율성과 안전성의 적절한 조화를 꾀하는데 목적을 두고 있다.

Purpose: In fire case, nursing hospitals are subject to considerable restrictions on evacuation due to the characteristics of occupants and vulnerable elements of buildings, it is important to make evacuation device for vulunerabale person, and need how to intend to increase the efficiency of evacuation by fire and evacuation simulation with helper Method: The smoke characteristics were analyzed by time through fire simulation, finally, the number of helpers according to the day and night was entered, and the evacuation completion time was compared and analyzed using the evacuation simulation. Result: It was found that the evacuation time was shortened by more than 20% when the evacuation assistance device was used for the vulnerable, and the evacuation time was delayed by almost 70% in case of a fire at night compared to the daytime. Conclusion: If the horizontal and vertical evacuation device are effectively utilized in actual fire situations, a strategy appropriate to the situation is deemed necessary. It is expected that evacuation efficiency will increase based on the use of horizontal evacuation evacuation device and vertical evacuation device by developing evacuation manuals

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.

The importance of "Golden time", the early hours for saving lives in case of an accident, is being increasingly recognized day by day. Especially for marine accidents, it may take several hours for a rescue team to arrive, depending on location. Therefore, captains should always be prepared to handle situations independently. In this paper, in order to make better use of Golden Time in an emergency, we determined what the first consideration should be when selecting a ship evacuation route from perspective of the ship operator. To achieve this, we used maritime accident judgments and ship emergency response manual to identify ship evacuation priorities. AHP analysis (decision-making hierarchy analysis) was conducted for ship operators to determine consideration priorities. As a result, it was found that ship operator consider the safety of people about 6 times more important than that of the actual ship. In order to select an evacuation route, the location of coast guard ships, port of refuge, emergency anchorage, surrounding vessels, drifting and beaching factor are taken into consideration. By using these priority considerations, the decision-making processes of ship operators in emergency situations can be improved.

This study introduce that we studied optimization and possibility of smoke spread prevention with air-curtain system in undersea tunnel named from Ho-Nam to Jeju line in domestic if a fire break out in train. To verify performance, air-curtain system is installed between rescue station platform and each door of passenger car to provide safety route to evacuator and we studied simulation model of various cases about 15 MW fire severity considering domestic specifications. As a result we verified the fact that CASE1(air jet with 15degree toward passenger car) and CASE 5 (air jet with 15degree toward passenger car and pressure air blast from cross passage) is best Smoke Spread Prevention and less inflow carbon monoxide. Through above results, we expect that air-curtain system is one of the facilities for fire safety and provide us safety platform route in undersea tunnel.

In this paper, a distributed evacuation system based on the positioning information of subway passengers is proposed. Recently, the subway station is becoming complicated by combining with shopping malls, and movie theaters. Compared to the increasing complexity of subway stations, evacuation systems are less complex. Subway passengers in each cell were estimated to use the access point in the subway cells and statistics information. The evacuation route is provided through a direction indicator and push alarm of a smart phone based on estimated the number of passengers and exit information of the subway station. Based on this schemes, a quick and safe evacuation system of subway passengers was proposed. The number of connection passengers was estimated using AP with OpenWrt embedded OS installed. The average error rate of the number of passenger was confirmed to be 15%, 17% and 23% at the confidence parameter of $1{\sigma}$, $2{\sigma}$, and $3{\sigma}$, respectively, through a simulation. The possibility of the system through a simple experiment was examined.

With emerging technologies on wireless networks and mobile computing environment, a number of researches have been carried out for ubiquitous computing. An important functional requirement of ubiquitous computing is to handle location data with ease. With the increase of accidents in large complex buildings. move attention is being paid to indoor spaces and evacuation. However, most currently used evacuation-related applications are simulation based on hypothetical data. Also, since they use non-georeferenced CAD data, it is not easy to integrate them with indoor positioning devices. With the recent progress of indoor positioning systems, the simulators can be enhanced to real-time evacuation systems. As a preliminary stage to make such systems possible, this study proposes using a georeferenced data and evacuation simulation. This study used GIS data and Cellular Automata theory an the algorithm for the movement of the evacuee.
