This paper examines the outcomes and tasks of U rail privatization especially focusing on the rail safety. Earlier research which focused on the rail safety had little knowledge of the explanations for recent changes of safety scheme. Moreover, they had difficulty making a direct comparison of safety between national rail and the privatized rail. Therefore we are left without a good explanation which has a comprehensive perspective. I attempt to show the outcomes of safety in the rail privatization process and its tasks focusing on the recent fatal accident. This paper argues that the UK's rail safety has a framework which is too complicated with overlapping responsibilities that brought about inefficiency, increasing costs. Especially infrastructure enterprise did not come to play an appropriate role. However, after 2000, the government took charge of setting the strategy for railway safety, and the Office of Rail Regulation covered safety, performance and cost. I explain that these changes present a good opportunity to solve the problem of passing the buck for rail accident. Through the analysis, I find that outcomes of rail privatization in safety are improved comparing the national rail. However, safety performance, for example the collision of structures of cars and looseness of rail should be improved. In future, the problems of fatal accident and a bit of duplicate safe system should be addressed.

해양사고로 인한 경제적, 환경적 피해가 커짐에 따라, 해양사고 방지를 위한 이슈가 크게 대두되고 있다. 발생된 해양사고 사례의 종류와 원인을 분석하여 구축된 DB가 해양사고 방지를 위한 연구에 널리 활용 되고 있으나, 하나의 종류 및 원인에 대해서만 DB가 구축되어 있어 일반적으로 복수의 원인에 의해 발생되고 복수의 종류에 해당하는 해양사고를 합리적으로 분류하지 못하고 다양하고 막연한 조건을 이용해 검색할 수 없다는 문제점이 있다. 따라서 본 연구에서는 FCM을 이용하여 복수의 해양사고 원인과 종류에 연계된 해양사고 DB를 구축하고 언어 레이블을 이용하여 다양한 원인과 종류에 의해 해양사고 사례추출이 가능한 검색 시스템을 제시하였다.
