The Emergency Exit System is evacuation equipment that operated by crew or passenger when emergency state such as fire, accident, etc in the rolling stock. Generally front emergency exit is installed in the drivers area and it is isolated to passenger area, so its design is little big easy. But front emergency exit that is installed in driverless vehicle have to consider not only anti-vandalism and failure but also its design because it is installed in the passenger area. Therefore, we survey the characteristic, function and needed condition the emergency front exit of driverless vehicle and present the developing system that can be a help to make design.

Due to almost all tracks of new Kyoungbu high-speed lines(HSL) consisting of bridges and tunnels, HSR operational safety management is very important factor for passenger safety and preventing catastrophic event. Especially, it is important to approach the scene of the accident and assist in saving lives as soon as possible under emergency conditions. Therefore it is essential to prepare access methods and available resources in advance in order to support emergency correspodances promptly and effectively. This paper persents an application of geographical information system(GIS) for developing emergency management system as well as batabase system on tracks and facilities, electric/communication equipment and safety equipment required to support emergencies. The on-site information on the proximity of HSL is expressed on the numerical map, which can be helpful to call external supports such as medical service, local authorities, police offices, fire brigades, and etc. for the emergency situations.

It is natural that The government should be responsibility for the fulfillment of obligation to prevent a notional life, accurate rescue and first-aid from various calamities. Although, The government policy is established a foundation that is reventing a national life and a property from the calamity with deciding of the fire line, that is not satisfied with taking precautions against a calamity. In case of the calamity there is always pointed the confrontation procedures, especially, In case of crisis The government is lacking to come to an developed country on account of system of the emergency rescue and first-aid. The prevention and provision are the most important thing with reference to a confrontation of the calamity. But calamity is happened without warning, so We should establish line of prompt rescue and first-aid lately that is very important thing. The First, We should get the single line of the rescue and first-aid through a integration and elimination in terms of a law of the emergency rescue and first-aid, but also we strengthen a line of a scene confrontation ability and speciality. To raise awareness of improving a rescue and ability of first-aid, through reinforcing the human and material equipment of The 119 rescue party to charge of emergency rescue and first-aid in effect.

Purpose: This study is to examine the relationship between safety awareness and safety accident occurrence with elementary school students. Materials and methods: It selected 10 elementary schools under the supervision of Jeonnam Board of Education and sampled 700 students randomly from 2-3 classes in the 5th and the 6th grade. One preliminary survey was conducted to revise and complement the contents and forms of questionnaire with 70 students of a school from Apr. 1 to 6, 2004 and this study was conducted from Apr. 10 to 30, 2004. Total 700 questionnaires were distributed and 681 were collected (97%) and 602 were used for final analysis except 79 lacking responses. Data collected were analyzed with SPSS statistical program. Results: The average score of safety awareness of subjects by area was high as 2.72 points out of a possible 3. Area showing the highest safety awareness was safety from fire. Girl students had higher safety awareness than boy students. The fifth graders had higher safety awareness than the sixth graders. In safety awareness by the number of siblings, single son or single daughter showed the highest safety awareness. 53.2% of the subjects experienced accident for one year, the frequency of accident was mostly once and most of accidents were occurred at school. Accidents for the last year were higher in boy students, the sixth graders. According to relationship between safety awareness and safety accident, group with lower safety awareness in school safety(P < .022), traffic safety(P < .016), fire safety(P < .019), home safety(P < .007) and accident treatment and first aid(P < .003) had higher safety accidents than that with higher safety awareness. Conclusion: Development of safety education program by grade, that of parents safety education program, field experience and practice with students, teachers and parents and various safety education programs should be substantially and repeatedly accomplished for prevention education of safety accidents. In addition, to prevent and cope with safety accidents, safety education should be reflected on normal education, safety education textbook be developed, special safety education teachers be employed for safety education.

The ESS load test device (ELTD) can store and exchange electrical energy during the load test of an emergency generator. On the other hand, it is difficult to commercialize ELTDs based on Li-ion batteries because of the high initial cost, which is higher than a load bank test. If the trade of electrical energy stored in ELTD during the test of an emergency generator is considered, it may be possible to commercialize the ELTD. Therefore, this paper proposes an economic model of ELTD composed of the costs and benefits by considering electrical energy trade to perform accurately economic evaluations of an ELTD. From the simulation results of the economic evaluations of an ELTD and the load bank method, it was found that the commercialization of ELTD is possible when the trade in electrical energy in ELTDs is considered.

This paper is concerned with simulation exercises used to train key response agencies for crisis situations. While 'multi-agency' simulations are increasingly acknowledged as a necessary and significant training tool for emergency response organisations, many current crisis simulations are still focused on the revision of existing response plans only. However, a crisis requires a rapid reaction, yet in contrast to an 'emergency', the risks for critical decision makers in crisis situations are difficult to measure, owing to their ill-structure. In other words, a crisis situation is likely to create great uncertainty, unfamiliarity and complexity, and consequently should be managed by adaptive or second order expertise and techniques, rather than routine or structured responses. In this context, the paper attempts to prove that the current practices of simulation exercises might not be good enough for uncertain, unfamiliar, and complex 'crisis' situations, in particular, by conducting case studies of two different underground fire crises in Korea (Daegu Subway Fire 2003) and the UK (King's Cross Fire 1987). Finally, it is suggested that the three abilities: 'flexibility', 'improvisation' and 'creativity' are critical in responding to a crisis situation.

This paper proposed that the method be searched for optimal route of evacuation by algorithm using potential field in specific situation, fire. When robot met an obstacle to be indicated it to ignition point, the installed sensor could be detected the point in restricted area. In according as the data of a fire detection sensor and a sensor complex in a building, the information was transmitted to server which computed optimal route of evacuation by algorithm using potential field. After that, it was able to blow a siren and mark the safe-path with using wireless device such as smart-phone. It was confirmed that the proposed method in functional test, fire emergency evacuation algorithm using potential field, was advanced in circumstance of simulation.

Fire loading causes a critical collapse of RC (Reinforced Concrete) Structures since the embedded steels inside are relative week against high elevated temperature. Several numerical frameworks for fire resistance have been proposed, however they have limitations such as unstable convergence and long calculation period. In the work, 2-D nonlinear FE technique is proposed using Galerkin method for RC structures under fire loading. Closed-form element stiffness with a triangular element is adopted and verified with fire test on three RC slabs with different fire loading conditions. Several simulations are also performed considering fire loading conditions, water contents, and cover depth. The proposed numerical technique can handle time-dependent fire loading, convection, radiation, and material properties. The proposed technique can be improved through early-aged concrete behavior like moisture transport which varies with external temperature.

Purpose : This study is a descriptive research to provide basic factors of posttraumatic stress in Firefighters. This study was carried out to develop the effective program for the fire fighters to cope with the posttraumatic stress following the disasters. Methods : The questionnaires were collected among fire fighters who serviced in K and I community from April 1 to June 30 in 2008. Total 304 questionnaires were analyzed by SPSS WIN program for descriptive statistics, Pearson's correlation coefficient and t-test. Results : 1. 48.0% of 300 fire fighters were at the age of 31-40, and 42.3% were under 30. 2. Work burden had a significant difference of 2.30 in low-risk group, 2.60 in high-risk group(t-value=-3.85, p=0.00). However, life event had no significant difference 0.79 event in low-risk group, 1.41 event in high-risk group(t-value=-2.27, p=0.24). 3. Concerning posttraumatic stress factors, there was positive correlation between mobilization impact level r=0.38(P<0.01), work burden r=0.38(p<0.01), and life event r=0.27(p<0.01). 4. According to the Symptom Check List-Revised(SCL-90-R), somatization had a significant differences(t-value=5.46, p=0.00), obsessive-compulsive(t-value=7.16, p=0.00), interpersonal sensitivity(t-value=6.15, p=0.00), depression(t-value=6.62, p=0.00), anxiety (t-value=7.33, p=0.00), hostility(t-value=5.94, p=0.00), phobia anxiety(t-value=6.85, p=0.00), paranoid ideation(t-value=5.55, p=0.00), psychotism(t-value=6.52, p=0.00) in low-risk and high-risk group. Conclusion : As a consequence, mobilization impact, work burden, and life event were the influential factors on posttraumatic stress. Also, high-risk group revealed significantly higher score on all 9 scales. The information obtained from surveys made recommendation to develop the intervention of stress management to control mobilization impact and posttraumatic stress.
