In response to the government's recent attempts to introduce competition and efficiency criteria in the rural railway service provision, this study is to empirically estimate public service values on continuous operation of two rural railways-Young Dong Line (YDL) and Donghae Nambu Line (DNL)-that will be realized beyond the passengers' use values. Based on a contingent valuation survey conducted on 600 passengers and local residents, YDL respondents were willing to pay significantly higher amount compared to those of DNL respondents. Especially tourists traveling on YDL were willing to pay the highest amount, and local residents of DNL were willing to pay relatively high amount. The results will provide useful information in makings decisions on the selection of PSO railways, the amount of PSO compensation and which railways to close, so on.

Prior to the service evaluation, many kinds of its attributes must be identified on the basis of rational decision owing to complexity and ambiguity inherent in logistics service. there are so many evaluation methods but they are not applicable to logistics service the have property of non-additivity and overlapped attributes. Therefore, probability measure can not used to evaluate logistics service but Fuzzy Measure is required. And the method should be easy to calculate it Recently Fuzzy theory has been applied in Various evaluation problem. Fuzzy evaluation based on Fuzzy theory can accommodate fuzziness in judgement with people through introducing Fuzzy Measure. In this paper, Hierarchical Fuzzy Process is applied to evaluate level of logistics service in Korail and the biggest six logistics companies in the korea which is called 3PL Company. Also Fuzzy Relation Equation which is problem identifying evaluation value at these fuzzy evaluation is applied to verify relation between Input and Output data through @-operation. Therefore, we apply this Fuzzy Relation Equation to Hierarchical Fuzzy Process and verify evaluation value which objects of evaluation are able to possess.

Organizational abilities which assure human resource of excellent quality in enterprise and organization, manages human resource effectively and systematically will be depended on the performance and successful or not of enterprise. The organization which readies to accept changes will survive, the organization makes full use of changes to opportunity and strategy will be a winner. Now when the environment of enterprise is uncertain and environment of management changes, organization should manage HRM in strategic point of view to maintain persistent competition superiority. We investigated how outsourcing affected on organizational performance perception according to inducting BSC from the employees of metro. As a result of the investigation, outsourcing is perceived importantly in study, growth, internal process point of view, but didn't perceived in finance and customer. We guessed that outsourcing would be perceived importantly in financial point of view as a cost reduction. In 5 years from the beginning of metro, it seemed to be perceived importantly, as organizations grow older, perceptions of outsourcing are perceived low because of stabilization of organization and labor's resistance. It is why that the more outsourcing is performed, the more reduction of organization and decrease of employees is expected as much as cost reduction.

Competition between air transportation and railways has grown fiercer in major countries around the world with the rise of high-speed railways. In South Korea, air passenger travel has been rapidly decreasing since the initial launch of the Seoul-Pusan KTX line in 2004 and second opening that followed in 2010. Further expansion of the high-speed railway is expected. At present, research efforts to verify the validity of constructing an underwater express railway tunnel between Ho-nam and Jeju Island are taking place. Considering the possible high speed railway connection between Seoul and Jeju Island, this thesis has analyzed the choice behavior of existing passengers of the major and low-cost carriers. For this, Stated Preference (SP) research has been performed for three variables, including fare, travel time and the number of runs, to estimate the substitution rate of each of the three variables. Binomial Logit Model has been estimated with the obtained data. The estimation of the model has found that airline passengers of major and low-cost carriers are willing to pay approximately 7,200 KRW and 5,000 KRW, respectively, to reduce travel time by one hour. If the number of runs in one day increases, it has been estimated that the passengers are willing to pay additional fares of about 390 KRW and 30 KRW, respectively. On the other hand, the substitution rate between the number of runs and the travel time was found to be somewhat insignificant. If the construction of the Seoul-Jeju line progresses in the future, this study could be used as preliminary data for determining fares, travel time and the number of runs.

선로용량은 수요에 부합되는 최대열차횟수를 결정하고 수송력 증대에 필요한 투자우선순위 판단을 위한 중요한 척도이다. 특히 2016년 중반부터 고속철도노선에 두 철도운영자가 운송사업을 개시함에 따라 선로용량과 실제배정 가능한 최대열차횟수 간에 상충이 발생하지 않고 유효운송경쟁이 보증될 수 있도록 선로용량을 산정 관리할 필요성이 있다. 열차종별 운행횟수, 도중정차패턴과 착발시각, 운행시간, 열차의 대피 또는 교행, 열차간의 안전시격 등에 따라 선로용량이 크게 달라지므로 현재까지도 실제 적용에 많은 논쟁이 있는 것도 사실이다. 이러한 문제점을 극복하고자 철도운영자의 운송정책을 고려한 열차운행 스케쥴을 반영할 수 있는 시뮬레이션 기법에 의한 선로용량 산정방법을 제시하고자 한다.

This study aims to assess the potential competition among road, rail, and coastal transport under various scenarios concerning the future inland container transport systems in Pusan-KyungIn corridor. For this SP approaches are adopted to collect data from shippers and carriers, and multinomial logit models are estimated at disaggragate level. The results of the analysis indicate that the SP data are reliable, and that the mode choice models estimated are valid. The results also indicate that the most effective policy to divert the freight volume from road to other modes is to reduce freight rates for the railway, and is to transport time for the coastal water with improved reliability.

The study on the user-centered interior design of trains consists of the practice of sensitive technology for the management of customer's emotions and its harmonical use on design and it aims on the embodiment of new ergonomics design. In the center, it has analyzed the criteria and characteristics for the 'User First Design' and has concluded the design direction and components to a concrete idea and proposed prototypes, which may becomes a good example for train interior design later on. And not at least it proposes a direction which may become a guideline of ergonomic design to secure competition capacity.

In this study, market strategies for the HSR's fare system are suggested for successful operation of high speed train opened in April 2004. For price strategies, we suggested HSR's fare system considered competition with other transportation modals are supposed to be charged and some discount-fare policies compared to service distances are needed for the successful operation of high speed train after the train open. In addition, this study concludes that for non-price strategies, various services for customers driving for enough demand can provide the base for stable operation of high speed train in Korea by making balances or profitability.

Since the operation of subway line 1 between Seoul and Cheongryangri stations in 1974, the rail length and riderships have been increased during the three decades. Furthermore, it was a remarkable increase of line length between 1995 and 2004 by the operation of Lines 5, 6, 7, and 8 within Seoul metropolitan area. This study reports the variations of riderships by the changing urban spatial structure. According to analysis results by station-to-station origin-destination trip tables, there were increasing ridership changes in new stations within new subcenters, while there were little ridership changes in old stations within Seoul and existing subcenters. The levels of competition between the existing and new lines brought about the difference of ridership changes.

The purpose of this study is establishing effective multimodal logistics structure in northeast Asia. For this end, the interface between transport modes, construction method of rail-ferry transport system, system operation and implementation strategies by step were studied. Rail-ferry system have a competition over present transportation system in international cargo trade market between Korea and China. And, the operation of rail-ferry transportation system between Korea and China is meaningful project in the point of providing various choices to clients. Korea and China should have agreements in trade, customs duties, ports in the next year for the success of this project.
