Quantitative RAM (Reliability, Availability, Maintainability) is the one of the important indicator that shows the quality of rolling stock. It is usually required in the domestic and abroad purchase specification of rolling stock. And achieving and demonstrating the quantitative RAM goals is also required. In this study, the method to set up these goals will be proposed in the aspects of service and logistic reliability, operational, achievement or inherent availability and maintainability. And we apply this proposed method to the real operation data.

One of railway communication technology, LTE(Long Term Evolution) based LTE-R(LTE-Railway) is rapidily adopted to supply various control signal and to supply diverse communication service be needed for safety operation of train. In this paper, railway communication technology and service based on LTE-R is studied. And domestic an international standardization trends of related on railway communications are investigated. Results of this study can be used as basic data for research of railway communication based on LTE-R and development of railway communication systems.

1899년 9월 18일 경인선 철도가 개통된 이래 우리철도는 100년이 넘는 역사를 가지고 있다. 1970년대 경부선 최고속도를 140km/h로 향상시킨데 이어 현재 우리나라는 건국이래 최대규모의 사회기반시설인 경부고속전철 사업을 추진중이며, 2004년에 300km/h급 고속철도 서비스가 개시될 예정으로 경부축의 상대적 거리는 더욱 가까워지면서 발전이 촉진되지만, 타 지역의 개발은 상대적으로 지체됨에 따라 국토의 편중개발로 인한 지역적 불만을 초래하게 될 것으로 예상된다.(중략)

국내 철도사업은 1899년 경인선이 개통된 이래 1970년대까지 지역 간 수송수단으로써 여객은 물론 산업물자 수송 등을 통해 국가 경제 발전의 초석이 되었으나, 1970년대 이후 고속도로의 투자와 함께 자동차 대중화 시대를 맞이하면서 철도는 도로교통에 지배적 위치를 내어 주게 되었으며 계속되는 투자부족과 수송시장의 변화에 대처하기 어려운 철도운영체계로 인해 서비스 수준 저하, 수요감소, 수입 감소로 이어지면서 경영적자를 야기하고, 이러한 재정적 어려움은 재투자를 어렵게 하는 등의 구조적 악순환이 반복되고 있다.(중략)

The purchasing behavior of consumers is related to service quality and corporate social responsibility (CSR). Therefore, CSR is recognized as an important factor in company strategies. This study determines the relationship between the CSR activities of KORAIL and the reuse intention and recommendation intention of the consumer. CSR is composed of economic, legal, philanthropic, ethical, and environmental responsibilities. In the results of the structural equation modeling analyses, legal responsibility and economic reliability affect the reliability of KORAIL and this reliability affects the customers' reliability and loyalty. This paper proposes a compliance program, wagon safety information, customized tour packages, and communication strategy that will increase customer's reliability and loyalty.

After the railway reform in 2004, Korea National Railroad was divided into two separate organizations. The Korea Railway Network Authority is responsible for the construction of new line. Korea Railroad corporation is a public-owned railway operator. The compensation for the loss of rail operator from the Public Service Obligation(PSO) observance is specified in the Law of Rail Industry Development No.32, No.33. However, it is necessary to revise the compensation criteria of PSO after the actual enforcement of the law for more efficient rail operation. This study aims for revising compensation criteria of PSO. In this study, we suggested a revised compensation criteria. The scope of compensation for the loss of regional line operation was adjusted by new criteria considering the characteristics and the business results of the line. The compensation rate is linked with the actual business results of the line for giving motivation to the rail operator.

Reliance on road transport in domestic logistics can lead to intensified congestion and greenhouse gas emissions due to the rise in oil prices, any increase in logistics costs can have a high social cost. The government policy on Low Carbon Green Growth is seeking to take advantage of the railway system. However, existing railway transport logistics systems, for reasons such as low speed, low track capacity constraints, and the impossibility of implementing a Door to Door system, make it difficult to activate a railway logistics program. As a result of this study, a national R&D project to develop a High-Speed Passenger/Baggage Mixed Train(Hy-SoBex) utilizing the rail capacity constraints to overcome the difficulties of linking an air cargo and freight railway logistics system, we propose a variety of service models and select the optimal service model.

This Paper presents a concert of Public Service Obligation related with validity, suitability and rationality. As we know, The Public Service Obligation of KNR is a largest factor of loss in the Railroad Industry. In the future, PSO concept and Calculating methods have to be changed for providing rational Public service based on the various focus.
