Recently, a massive loss of life and property is occurring in Korea due to traffic accidents, with the rapid increase in cars. For improvement of traffic safety, the Korea Transportation Safety Authority intensively analyzes accident data in local governments with low traffic safety index, performs a field investigation to extract problems and offers local governments improvements for problems, by conducting the 'Special Survey of Actual Conditions of Traffic Safety' each year, starting 2008. But local governments cannot strongly push forward the improvement projects due to the limited budget and the uncertainty of the improvement plan effects. Therefore, this study suggested a model which applied the Utility concept to the AHP theory, in order to efficiently decide a priority of the improvement plans in accident black spots in consideration of the limited budget of local governments. The number of accidents in each spot for improvement and accident severity, traffic volume, pedestrian volume, the improvement project cost and the accident reduction effect were chosen as evaluation factors for deciding a priority, and data about the improvement plan costs and the accident reduction effects, traffic accidents and traffic volume in the spots to undergo the special research on the real condition of traffic accident in the past were collected from the existing studies. Then, regression analysis was carried out and the Utility Curve of each evaluation factor was computed. Based on the AHP analysis findings, this study devised a priority decision method which calculated the weight and the utility function of each evaluation factor and compared the total utility values. The AHP analysis findings showed that among the evaluation factors, accident severity had the biggest importance and it was followed by the improvement plan cost, the number of accidents, the improvement effect, traffic volume and pedestrian volume. The calculated utility function shows a rise in utility, as the variables of the 5 evaluation factors; the number of accidents, accident severity, the improvement plan effect, traffic volume and pedestrian volume increase and a fall in utility, as the variables of the improvement plan cost increase, since the improvement plan cost is included in the budget spent by a local government.

본 연구의 목적은 독거노인의 안전의식과 주거환경의 연관성을 알아보고, 이들 간의 관계에서 독거노인의 사고 발생 빈도 및 유형을 통해 안전의식 증진을 위한 개선방안을 모색하고 도출하고자 함이다. 본 연구는 생활관리사 22분의 도움을 받아 성남시 수정구에 거주하는 노인 총 67명을 대상으로 설문조사를 실시하였으며, 연구에 필요한 20개의 논문을 정독한 후, 자체 제작한 주거환경 체크리스트 도구, 안전의식 진단 도구를 사용하여 설문지를 작성하였다. 독거노인들의 주거환경에 따른 사고 경험을 분석한 결과, 사고유형과 사고장소에 대한 유의한 차이가 있었다. 또한 독거노인의 안전의식에 대한 설문에 의해 외출 시간과 안전의식이 상당한 연관성이 있다는 사실을 새롭게 알아내었고, 그 결과 상대적으로 집에 머무르는 시간이 긴 노인이 안전의식 수준이 높았다.

Maritime transportation is one of the most complicated and hazardous business fileds. Maritime accidents still occur despite several precautions since maritime is exposed to natural factors more than any other industries. In this harsh environment as a part of their job, marine pilots often embark/disembark to/ from vessels and confront life-endangering personal accidents. In the maritime field, several risk assessments are applied. However, all of them could not evaluate occupational accident risk for maritime pilot specifically. This paper performs specific risk analysis using the bow-tie method based on past accident records. This paper aims to qualify root causes and quantify root causes by importance level according to occurrence probability. As a result of analysis, occupational accident occurrence probability is found to be 14%, indicating that accident occurrence rate is significantly high. Hence, the probability of root causes triggering accidents and accident occurrence probability can be ascertained so that preventive measurements can be implemented. Besides theoretical achievement, this paper provides safety awareness to marine pilots, Marine Pilot Organizations, and ship crew who play a key role during marine pilots' transfer.

Aging society may approached to our society during snatch very, and enter in super aging society for more span. Investment that we which live 21th century are many in people's quality of life elevation meantime did not consist, but stand in visual point that must improve many portions forward. For front, repletions for many equipments that consider aged on our society must consist, and much researches may have to be gone for this. According to traffic accident result, percentage of older pedestrian deaths was 46.5% as much in Korea. In particular, the crossing accidents by 59% or more of the older pedestrian traffic safety measures that target is an urgent situation. Therefore, in this study was to identify the domestic status and problem on no-sidewalk region for older pedestrians. In addition, side walk the installation and maintenance plan presented to prepare for aging society.

In order to reduce the damage of life and property caused by an automobile accident, we should design new car models and safety standard with reference to the data analysis and in-depth investigation of the accident. In-depth research and analysis of the current world other than the police investigation team (GIDAS, iGLAD, NHTSA, etc.) and collect in-depth data. Going to develop a safety policy to make it much safer cars based on this data. However, the country still does not have the advantage of KIDAS data Safety Policy Direction. In KNCAP tests, there is nothing in order to protect far side passengers even if far side impact causes approximately 50% injured people. Based on DBs like KIDAS (Korean In-Depth Accident Study) and GIDAS, far side passengers got injured as much as near side passengers did. So as to protect far side passengers, KNCAP has to change the test method of side crashes. In this study, injury severities to compare with ES-2, World SID and Thor dummies and the movements of far and near side passengers, SLED TEST was used.

The purpose of this study was to measure safety-awareness among elementary students, identify their safety-practices and actual status of accidents. The study was also done to acquire basic information on safety education to help students be more aware of safety, and more active in accident-prevention activities. A random sample was taken of 763 5th and 6th grade students in 4 different elementary schools in Seoul. Of the 735 questionnaires collected, 684 were complete and were used in the analysis. SPSS was used to analyze the questionnaires. The results are summarized as follows. First, the overall safety-awareness score was relatively high at 139.06 of a maximum of 164. and respondents were most conscious of the section on Home Safety. Second, the safety-practices of the respondents was at the middle level with a mean score of 56.01 of a maximum of 80. The factors affecting the safety-practice of the respondents were education of their parents, recognized learning proficiency, awareness of need for safety education, and level of safety-education conducted by parents. Third, $53.4\%$ of the respondents had experienced one or more accidents during the past year. Most of the accidents occurred during play and recreation and home accidents were the most frequently reported accidents. The risk factors related to the occurrence of accidents were gender, relationship with friends, recognized learning proficiency, and awareness of traffic safety. Forth, higher safety-awareness was found to be directly related to higher safety-practices. Respondents with lower safety-awareness reported higher rate of accidents. In view of the results so far achieved, habituation and formation of safety-oriented actions among students are highly required to prevent accidents. In order to do that, development of safety-awareness and in-life enforcement of safety-practice need to come first.

A railroad has a benefit of the mass transportation of a passenger and cargo, but just a time of accident could cause a huge loss of a human life and property. Especially, a typhoon and a localized torrential downpour usually happened in summer season have caused average 38.29 times of the missing roadbed which support the railroad in recent 7 years. If a train would pass on this railroad which the roadbed was missed, there could be a huge accident and many people will die. But, the security issue is not satisfied because the method of sensing the missing roadbed is depending solely on the naked eye inspection by a person in charge. So, in this study, I would like to suggest the missing roadbed real-time sensing and train operation system to reduce the possibility of the railroad accident by controlling the operation of train when the missing roadbed condition would be sensed in the real-time system.
