김동진 우송대학교 철도대학원 2012 국내석사
The Korea's railroad has continued making operational loss due to its public nature. In fact, the railroad is supposed to be run by the business operators with the strong nature of corporate management, but it has been organized as one of the government organizations where rigidity and publicness, instead of managerial flexibility and efficiency, are emphasized. However, such an organization is no longer suitable for managing the railway under the circumstance that the exclusiveness and the publicness are weakened due to the development of competitive means. Thus, the restructure of organization has been carried out as a new system where the responsibility management is possible with the autonomy of management, and Korea Railroad Corporation is established as a part of its privatization. In case of Japan, in the operational system of railroad, the factors for the private management are actively introduced to improve the management effectiveness while ensuring the publicness of railroad at maximum for the improvement of its productivity and the operational system of railroad is switched over to Responsibility Management System. Since the privatization, Japan considered that it was difficult for the railroad itself to make an operational profit, so the railroad expanded its business into the subsidiary businesses and operated its businesses in the black. Thus, Korea's railroad also has to pursues the publicness of railroad under the system of public corporation, a step towards the privatization, should prepare the foundation for the self-supporting management and the operation in the black. To do this, it was concluded that it is necessary to break from the railroad-centered business structure and diversify its business into the related business. On the same lines, Korea Railroad Corporation has made 12 subsidiary companies in 2004. However, they made a huge operational loss due to the poor management of its subsidiary companies and the lack of infra-structure and, as a result, many subsidiary companies were sorted out and integrated, and now there exist only 9 subsidiary companies. The current railroad business is in the transition to the relevant diversification based on its core competence rather than the business expansion through unreasonable diversification. However, the impractical advancement into many fields in such a short period of time was the reason for the huge loss without the support from internal competence and the investigation of the core competence. Railroad is no longer the transportation means transporting the passengers and the cargoes, but switches over to the center of our life. It is about time to seek for the suitable methods for our railroad business like the subsidiary businesses of the subsidiary companies of JR in Japan, through the analysis of internal competence and external environment. Thus, in Chapter 4, an analysis of the external environment and the core competence of Korea Railroad Corporation was performed. As a result of the investigation of the core competence of Korea Railroad Corporation, the operational techniques and the railroad facilities operating the nationwide railroad network have been found. When looking into the subsidiary business fields based on these competences, there are overseas' business, real estate development, and leasing business. Because they are associated with the railroad business, they can be called the related subsidiary businesses. Also, as the growth of the railroad will continue, above businesses will correspond to the medium-long term direction of Korea Railroad Corporation. To promote these businesses, it is needed to carry out the businesses successively according to the importance and the competence through considering the errors of Korea Railroad Corporation in the past, rather than carrying out them simultaneously, and provide the improved railroad facilities for the public through becoming a part of the life of the public through intimate approach.

TCIM 기법을 이용한 전기철도 급전시스템 해석 및 유․무효 전력보상장치의 최적 운영 방안에 관한 연구
이병곤 우송대학교 철도대학원 2022 국내박사
고속철도 건설에 따른 고속노선과 건설 후 수십 년 이상 경과한 기존선로가 병존하여 열차가 운행됨에 따라 속도 저하 및 경부․호남고속철도 열차 운행확대에 따른 선로용량 확충이 필요하다. 또한 전기를 공급하는 철도 급전시스템은 일반적으로 길이가 길고 변전소간 연장급전 운용할 때 부하의 증대에 따라 전압강하가 크며 역률 저하 등이 발생됨에 따라 이를 고려한 전력품질의 안정화 대책 수립이 필요하다. 본 논문에서는 전기철도 시스템 운용효율 향상을 위한 전기설비의 최적 시나리오 도출 및 운용기법 분석하여 성능을 검증하고자 총 다섯 가지 알고리즘을 제안하여 분석하였다.
