2005년 철도구조개혁 시행에 따라 한국철도공사가 출범하였고, 철도운영자가 제공하는 공익서비스비용에 대하여는 철도산업발전기본법 제32조 및 제33조에 의해 원인제공자가 보상토록 규정하고 있다. 이에 따라 공익서비스비용의 보상은 '05년도 처음 시행되었으나, 비용 산정의 적정성 및 기준 미비 등으로 보상규모의 공정성 객관성에 대한 외부기관으로부터 문제가 제기되었다. 따라서 본 연구에서는 국내외 유사사례를 검토하고, 공익서비스비용 보상의 주요항목인 벽지노선의 적정한 선정기준 및 비용 산출, 운임감면액 보상범위 등과 관련하여 문제점과 개선방안을 살펴보았다.

최근 건설시장 규모가 확대되고 교통산업이 발전하면서 지하철 및 터널 등과 같은 개착형 Box 혹은 Shield형 터널 구조물 등 지하구조물의 건설이 다양화되고, 그 수요도 점차 급증하고 있는 실정이다. 그러나 주로 지하에 건설되는 콘크리트 구조물은 시공시 신축이음 및 시공 조인트 등과 같은 다양한 형태의 조인트 발생과 구조물의 수축팽창에 따른 거동, 부동침하, 과다하중, 진동발생에 의한 균열로 인하여 누수가 발생되고 있다. 이에 다양한 방수공법 및 재료들이 현장에 적용되고는 있지만 지하철도, 지하철 등과 같은 진동 및 구조물의 거동이 상시적으로 발생되는 환경조건에서는 방수층의 성능이 저하되어 균열, 침식, 들뜸 등으로 물이 확산되어 재누수가 되는 악순환을 겪고 있는 실정이다. 따라서 본 연구에서는 진동 및 구조물의 거동에 대응 가능한 점착 유연형 복합방수공법을 대상으로 구조물의 거동 대응성 시험을 평가하고, 거동 및 진동이 상시적으로 발생되는 지하철, 터널 등을 대상으로 실제 현장에 적용 후 사례를 통해 구조물 거동에 대응 가능한 방수기술을 검토하였다. 이러한 거동 대응 특성을 검토한 결과 방수재가 기건 및 수중환경에서도 재료의 유연성과 부착성을 유지하여 물의 침투를 방지하고, 거동폭 $5.0mm({\pm}0.5)$ 범위에서도 거동에 대응 가능함을 알 수 있었다.

고속철도의 전차선로에 사용되는 유리애자는 국내에 적용 사례가 없으며 해외에서도 프랑스를 중심으로 한 정적으로 적용되는 품목으로서 국내 적용시 특성분석을 통한 적합성 평가가 요구된다. 본 논문에서는 2004년 이후 운영데이터를 바탕으로 유리애자의 현장 적합성을 평가하기 위해 전기적, 기계적, 외부적(환경) 요인의 3가지 대항목을 선정하여 분야별로 특성 분석을 수행하여 기초데이터를 축적하고 적합성을 평가하였다.

철도는 인터페이스 산업으로 철도차량 선로 관제 등이 유기적으로 맞물려야 움직일 수 있다. 이를 정상적으로 운영하기 위해서는 많은 유지보수 활동이 필요한데 이러한 활동과정에서 발생하는 데이터들은 각 분야별로 관리하고 있어 업무특성에 따라 위치, 시간 등 기준 데이터가 각각 상이하여 시 공간 기반의 통합 분석을 할 수 없는 실정이다. 각 분야별로 상이한 데이터를 통합 분석하기 위해서는 데이터마이닝 기법을 통해 유의미한 정보를 추출하여 분석하는데, 이러한 분석을 위해서는 데이터 유형의 상호관련성을 인지하기 위한 기준정보의 추출과 매핑이 반드시 필요하다. 본 연구는 서로 다른 분야에서 발생하는 안전과 관련된 데이터에 대한 매핑 툴 선정과 결과에 대하여 검증을 수행하고자 한다.

As of July 1999, i,185 lomocotives(excluding metropolitan area electric locomotives) are in Korean National Railroad(KNR). With this limited number of resources assigning locomotives to each trains of timetable is very important in the entire railway management point of view because schedule can be regarded as goods in transportation industry. On a simple rail network, it is rather easier to assign proper locomotives to trains with the experience of operating experts and get optimal assignment solution. However, as the network is getting bigger and complicated, the number of trains and corresponding locomotives will be dramatically increased to rover all the demands required to service all of the trains in timetable. There will be also numerous operational constraints to be considered. Assigning proper locomotives to trains and building optimal cyclic rotations of locomotive routings will result in increasing efficiency of schedule and giving a guarantee of more profit. The purpose of this study is two fold: (1) we consider a planning-level locomotive scheduling problem with the objective of minimizing the wasting cost under various practical constraints and (2) development of implementation prototype program of its assigning result. Not like other countries, i.e. Canada, Sweden, Korean railroad operates on n daily schedule basis. The objective is to find optimal assignment of locomotives of different types to each trains, which minimize the wasting cost. This problem is defined on a planning stage and therefore, does not consider operational constraints such as maintenance and emergency cases. Due to the large scale of the problem size and complexity, we approach with heuristic methods and column generation to find optimal solution. The locomotive scheduling prototype consists of several modules including database, optimization engine and diagram generator. The optimization engine solves MIP model and provides an optimal locomotive schedule using specified optimization algorithms. A cyclic locomotive route diagram can be generated using this optimal schedule through the diagram generator.

This study aims to analyze the characteristics of the management situation of the Korea Railroad Corporation(KORAIL) through the management innovation process of the KORAIL and to suggest its implications for military application. Despite stable demand, the railway passenger industry had the limitation of not being able to abolish deficit routes due to public service obligations. In addition, the launch of the Suseo High-Speed Line has introduced a competitive system, posing a threat to corporate management. KORAIL wanted to overcome this crisis by innovating its management through the utilization of big data, improvement of the freight business, decentralization of demand, the introduction of tourism railroads, and development of station influence areas. By utilizing big data, KORAIL was able to optimize the railway fare system while reducing fixed costs spent on railway maintenance. It also drastically reduced the station of cargo and created a base station to pursue economies of scale. On the other hand, the existing exclusive station system was abolished to solve the chronic saturation of the downtown area, and the railway demand was moved to Gwangmyeong Station and Suwon Station to optimize the passenger supply. In particular, it developed a new business model called the tourism railway by developing the mountain Byeokjin Line, which was a chronic deficit line, and sought to improve liquidity through the development of the station influence area. Such a process of innovation at KORAIL suggests an appropriate direction in seeking ways to innovate the military medical institutions. First of all, the necessity of improving organizational immersion through the development of a personnel structure suitable for the compulsory organization, while expanding the facilities of the division and corps, and reducing the time required for medical treatment and waiting through the establishment of a data-based medical system was suggested. Next, it was also discussed to integrate the National Health Medical College, which received accreditation as a medical facility through the designation of advanced general hospitals and is ultimately under discussion with the Medical Institution. Through this, we hope that the military medical institutions, which are facing various challenges, will overcome existing limitations and be re-lighted as innovative institution that provides comprehensive public health services.

The amended law of railway safety in Korea has recently come into effect in order to strengthen the railway safety management system. The new law, which took effect March 1, 2014, will implement stricter oversight of railway companies. As a result, a company that manufactures railroad system or components for domestic use must obtain an approval in accordance with the technical specifications of manufacturer approval. Although Korea had established the legal system in enforcing railway safety, the government wants the companies continue to develop the more improved safety systems until they gain competitive edge on the world class railway manufacturers. This paper presents an in-depth analysis of the technical specifications for manufacturer approval in International Railway Industry Standard (IRIS), which is the global standard. This paper also proposes measures and guidelines that would help Korean manufacturers those who want further develop their safety management systems, as a prerequisite for them to obtain the manufacturer approval.

이 논문은 프로젝트 관리 기법으로 널리 알려진 업무분담구조(WBS)에 관해 다루고 있다. 그러나 현재 국내산업에서 사용되고 있는 WBS는 잘못된 형식을 취하고 있다. 이러한 문제점은 WBS의 핵심요소인 물리적 계층 구조(PBS)가 공간 중심적으로 잘못 구축됨으로써 발생한다. 이 논문은 국내 철도 산업에서 작성된 PBS를 예제로 하용하여, 설계 구조 매트릭스(DSM)를 이용하여 기능 중심적 PBS로 새로이 구축하는 방법을 제시한다. 제안된 방법론과 프로세스는 빠른 시간 내에 올바른 PBS를 구축하는데 유용할 것이다.

Railway System has been developed by applying the advanced technology so that it reduces accident of hardware failure. But human error has been founded as important cause in railway accidents and safety. Medical condition is one of railway accident causes. Failure to recognize potentially incapacitating medical conditions can have serious safety consequences for railroad employees, the railroads and the public[1]. In order to find potential danger, we collect domestic/ foreign case for the medical examination and analyse characteristic/difference. The purpose of this study is to suggest information of employees' medical examination through comparing the current medical standard in railway industries.
