PURPOSES : The purpose of this study is to analyze the requirements of the road traffic safety moderator robot when road repairing. The road traffic safety moderator robot is road traffic safety equipment and to conversions mechanical engineering and IT when road repairing. METHODS: The study used AHP based on the survey from road repair related expert that field engineers, design engineers, public officials and professors. The survey used paired comparison. The survey items were safety, convenience and economics. The safety is classified as visibility or efficiency, the convenience is classified as utility or mobility and the economics is classified as initial investment cost or maintenance $ management cost. The survey alternatives were the road traffic safety moderator robot, traffic regulation by human, traffic regulation by mannequin and traffic signs. The software for AHP is Expert Choice 2000. RESULTS : The results of AHP analyze, the weighted value of safety was analyzed with the highest at 0.488 of survey items. The weighted value of convenience was analyzed at 0.295, the weighted value of economics was analyzed at 0.218. The results of the road traffic safety moderator robot, the weight value of efficiency and utility were analyzed with the highest at 0.284 and 0.259 of alternatives. The weighted value of initial investment cost and maintenance & management cost were analyzed with the lowest at 0.203 and 0.211 of alternatives. The consistency test results of each items, null hypothesis is rejected because the CR values were 0.000 respectively. Therefore, the study results are consistency.

해양안전심판원은 해양사고가 발생하면 그 원인을 규명하고 재결결과에 따 라 관련 당사자인 해기사들을 징계할 수 있다 이러한 해양안전심판원의 재결 은 사고관련 당사자에게 직접적인 효력을 미침은 물론이고 후속적인 민사 및 형사소송에까지 중요한 영향을 미친다 또한 재결은 해양안전심판원의 심판관 에 의하여 행하여진다 심판관은 재결을 행함에 있어서 증거를 기준으로 하여 심증을 형성하고 이는 현행 해양사고의조사및심판에관한법률 제 조의 규정에 의거하여 증거의 증명력은 심판관의 자유로운 판단에 따른다 는 규정을 근거 로 증거의 증명력을 인정한다 본 연구에서는 충돌사고와 관련하여 상반된 결과를 보여주는 중앙해양안전심판원과 부산지방해양안전심판원의 재결결과를 분석한 후 민사소송법과 형사소송법을 참고로 하여 심판관의 증명력 인정범위 에 대한 기준을 제시해 보고자 노력하였다 그 연구결과로서 해양안전심판의 특성에 비추어 기본적으로 의 증 명력 인정범위내의 증명력보강에 의한 상승가능성 포함 의 해석상의 기준을 제시하였다 다만 해양사고는 그 경중을 분리할 수 있는 뚜렷한 기준을 제시하는 것이 사실상 불가능하다 또한 본질적으로 행정심판의 성질을 가지는 해양안전심판 이 범죄에 대한 형벌을 부과하는 절차인 형사소송법과 동일한 정도로 증명력 인정범위를 강력하게 제한할 필요는 없다는 점과 직권주의에 의한 관여가 전 혀 없이 중립적인 입장만을 견지해야하는 민사소송법상의 입증보다는 더 엄 격해야 한다는 점은 인정해야 한다 이에 따라서 일단 자유심증주의가 규정되어 있는 이상 심판관의 증명력 인 정범위를 완벽하게 고정시키는 것이 어렵다고 할지라도 민사소송법과 형사소 송법의 증명력 인정범위에 대한 기준을 참고로 하여 증거의 확보가 어려운 해양사고에서 객관적인 사실인정을 위해서는 증명력 인정범위에 대한 기준으 로서의 수치화의 제시가 어느정도 필요하다는 점은 분명하다 이러한 관점에 서 본 연구의 증명력 인정범위에 대한 기준의 제시와 증명력 보강에 대한 해 석방향의 제시는 후속연구를 위해서도 필요하다고 판단된다

The goal of this paper is to suggest aircraft maintenance and its improvement for aviation safety. The purpose of aviation safety is to prevent aviation accidents resulting in damage to human life and property. Aviation safety relies heavily on maintenance. Human error is cited as a major causal factor in most aviation mishaps, including maintenance error. Errors can be described as active failures that lead directly to the incident, and latent failures whose presence provokes the active failure. Maintenance errors are parts installed incorrectly, missing parts, and necessary checks not being performed. In comparison to many other threats to aviation safety, the mistakes of an aviation maintenance technician(AMT) can be more difficult to detect. Often times, these mistakes are present but not visible and have the potential to remain latent, affecting the safe operation of aircraft for longer periods of time. State safety programmes is a system of activities for the aim of strengthening the safety and integrated management of the activities of government by standards of the ICAO. In summary, It is necessary to revise regulations on the basis of the aviation practice for aviation safety regulatory requirements. The goverment will eventually need to promulgate fatigue management standsrds for AMT also pay particular attention to the safety and education for small aircraft AMT.

Preschoolers are the most effective age to start fire safety education. But, if the education contents are inappropriate, they may form the wrong habit to preschoolers. Many educational contents of fire safety in Korea are not so obvious in the principle and order of priority about what to do during fire and they often contain unnecessary contents to preschoolers such as how to use fire extinguisher. This paper has analyzed fire safety awareness of preschoolers and teachers and, based on the results, has claimed unsuitability of training on how to use fire extinguisher and has suggested the improvement of fire safety education.

To assess the health risk for benzo(a)pyrene by the intake of edible oils, 288 cases of edible oils collected from food markets were analysed using the high performance liquid chromatography with fluorescence detector. The levels of benzo(a)pyrene were from non-detection to 4.78 μg/kg, and the average was 0.11 μg/kg. The chronic daily exposures of benzo(a)pyrene for total population group and consumer-only group were estimated using the food consumption data in the fifth Korea National Health and Nutrition Examination Survey in 2011. The estimated daily intake of benzo(a)pyrene was 4.26 × 10−3 ng/kg b.w./day for total population group and 7.64 × 10−3 ng/kg b.w./day for consumer-only group. The MOE (margin of exposure) of benzo(a)pyrene for total population group and consumer-only group was 7.28 × 107~1.74 × 108 and 3.95 × 107~9.42 × 107, respectively. Accordingly, the health risk from benzo(a)pyrene caused by the intake of edible oils was considered as a very low level.

The occupational injury and illness(OII) was influenced by the various factors. This study was planned to investigate the pathway of the activities of OSHM on the rate of OII via worker's participation. The survey on the trend of the activities of OSHM was used. The sample size of manufacturing industry was 3,000 enterprises and that of construction was 1,000 enterprises. The survey was done by interview method with structure questionnaire. Questions about the activities of OHSM were integrated into one category using factor analysis. The enterprises with OII has more activities of OSHM than that without OII. Among enterprises with OII, the level of the activities of OSHM was positively correlated with the rate of OII. The activities of OSHM has influenced on the rate of OII directly and indirectly via worker's participation and the activities of prevention of accident. Worker's participation also has the direct effect and indirect effect on the rate of OII. Worker's participation in construction sector has more effect on OII than that in manufacturing sector.

The disaster and safety accidents in any construction site occur inevitably. Since the on-site disaster and accident occurrence became one of major concerning factors in construction site, architects & building executers have been flooded with safety management advices. The purpose of this paper is to survey and analyze the effect of the application of Safety Patrol Management System(SPMS) upon the reduction of disaster & accident occurrences in construction site. In order to estimate and reduce the disaster and accident ratio in construction site, various surveyed data has been analysed. It will establish the suitable design standards and suggest the basic database for estimating disaster and accident ratio.

The rapid growth of complexity and scale can be witnessed in the design and development of modern systems. As such, the severity of damages in the occasional accidents has attracted great deal of attention lately. Although a variety of methods have so far been studied to overcome or reduce the disastrous results of hazards, the issues seem still persistent and even complicated due to the situation mentioned above. The concept of functional safety has been regarded as one approach to handling the matters by shifting up to the functions level from the consideration of each physical component itself. The outcomes of those efforts would be the international standards on functional safety such as IEC 61508 and its relatives including IEC 62278, EN 50128, ISO26262, and so on. In this paper, a method of how hazards can be analyzed to be coped with those standards has been studied. In the method proposed, the systems modeling language (SysML) is playing a key role to model and analyze the hazards from the viewpoint of functional safety. The approach taken has been applied in the analysis of the hazards in railroad systems. In spite of focusing on the individual components hazards, the method based on functional safety has analyzed them collectively with the added effect of identifying the cause originated from the interface between the functions.
