This study intended to exploratively testify human error causing factors for railway traffic controller, using AMOS structural equation model. Through literature survey, fatigue and stress as exogenous variable, errors in information process such as cognitive, memory, storage, and execution error as endogenous variable, and accident and incident(near-miss) as dependent variable were set up. Results based on AMOS using 201 railway traffic controllers' questionnaire showed that a clear causality loop like as 'stress ${\rightarrow}$ memory error ${\rightarrow}$ storage error ${\rightarrow}$ incident(near-miss) ${\rightarrow}$ accident' is formed. This result suggests that for the purpose of mitigation of traffic controller's accident, it is so necessary to reduce memory and execution error in the information processing process based on the effective management of stress, as the precedent of them.

This study suggests ubiquitous railway disaster prevention system that gearing Ubiquitous Sensor Network system information take to the subway fire accident information which emergency response procedure as occurring subway fire accident scenario. Also it is proposed that emergency response system though fire scenario. collected Information was analyzed each system over providing information and it is designed to exchanging information structure though relation system. The ubiquitous railway disaster prevention system basically consists by four unit stages as prevention, preparedness, response and recovery system. Especially, in this system can supply real time accident information to the relevant government offices and public through forecasting and warning system by utilizing recognition of the five senses in case of accident. also, it is build that to make decisions as linking 2-dimension and 3-dimension space information interface of ubiquitous sensor networks and expected scenarios.

As we learned in Daegu subway fire accident, fire in the railway tunnel is prone to develop to large disaster due to the limitation of smoke control and smoke exhaust. In railway tunnel, in order to ensure fire safety, fire prevention and fighting systems are installed by quantitative risk assessment results. Therefore, in this research, developed the program to establish quantitative risk assessment and suggested quantitative safety assessment method including fire scenarios in railway tunnel, fire and evacuation analysis model, fatality estimate model and societal risk criteria. Moreover, this method applys to plan preventing disaster for Honam high speed railway tunnel. As results, we presented the proper distance of escape route and societal risk criteria.

항공기 사고발생시 사고조사가 착수도 되지 않은 상태에서 노후 항공기를 사고원인으로 추정하여 보도하는 사례들이 발생되고 있다. 이러한 보도형태는 항공기 정비방식의 이해부족과 항공기 노후화와 사고의 연관성에 대한 연구의 부재로 나타나는 현상으로 볼 수 있다. 이에 따라 본 연구에서는 철도 항공사고조사위원회에서 사고조사가 완료된 조사보고서를 분석하여 노후 항공기가 항공사고에 미치는 영향을 연구하였다.

Even though accidents occurred inside urban railway stations demage not only one person, but also surrounding people, it can be prevented by cautious actions. This research aims at infants and children, which can maximize the educational impacts, to develop a safety textbook which can educate safety rules and behavioral know-how to reduce the accidents occurred in urban railway stations, and at parents and teachers to gather opinions through surveys on the research's future direction. This research conducts a case study and comparison analysis on domestic and foreign safety manuals, which is organized in a book form of fairy tales educating safety rules for readers to utilize the urban railway by steps from boarding to taking off. Through a survey we conducted for parents and teachers as providing the safety textbook developed through this research, we could get the positive evaluations and gather opinions on the future research direction. The safety textbook developed in a form of fairy tale book through this research is for infants and children to use the urban railway in a safe manner, which is expected to evoke the interests and curiosity and create the educational impacts on users.

현재 철도는 물류의 운송과 대중교통수단으로 다양하게 활용되고 있다. 또한 친환경적인 면에서 매우 중요한 교통수단으로 각광을 받고 있다. 이에 따라 철도의 안전은 고려해야 할 가장 중요한 부분 중에 하나이다. 특히 철도의 건널목과 역사 내의 플랫폼과 같은 개방된 공간에 대한 안전관리는 매우 중요하다. 개방된 공간에서는 사고발생의 위험요소들이 다수 존재하기 때문에 이러한 위험요소들을 줄이기 위해 열차의 1차적인 통제를 담당하는 기관사와의 상황인식 정보의 공유가 필요하다. 상황인식 정보는 특정 공간에 따라 다양하게 존재할 수 있다. 따라서 OSGi 플랫폼을 사용하여 다양한 상황인식 정보들을 공유하고 활용할 수 있도록 하는 것이 본 연구의 목적이다.

The railway accident is characterized by widespread and great(immerse) damage to our society when an accident occurred even if the probability of a railway accident is low. It is no doubt that the role of a rolling stock driver who are active in the first line of the rail safety driving is the most important to prevent an unexpected railway accident. Before new railway safety law being taken into effect, each railway operating organization had the responsibility of training a rolling stock driver by qualification criteria (the requirements or standards of competency), training period, probation period decided on their own standards. To train drivers driving same locomotive model, each railway operating organization had a variety of standards to draft and train trainees. Consequently, It was considered inefficient way to train and manage rolling stock drivers. However, after implementing the new railway safety law, a new system including training and evaluation process to issue driver's license on the condition that entire requirements are satisfied has been established. To prove the competency of the rolling stock driver objectively, training center and third-party evaluation center are divided individually and assigned by government office. Training center should design the training program to allot theatrical education time for different trainee group and to secure maximum practical training time utilizing simulator system to enhance the rolling stock driver's competency. This study analyzes certain conditions necessary to maximize the effectiveness and practical use of training for aquisition of a driver's license and the problems of the existing rail safety law and the ways to improve them.
