최근 여러 기업과 단체들은 전자상거래 관련 분야에 대한 연구개발을 활발하게 진행하고 있다. 새로운 비즈니스 프로세스가 제안되고 있으나 상거래 변화에 동반되어야 하는 물류 부분에 대한 연구는 상대적으로 미흡하였다. 구체적으로 화주와 운송업체의 물류정보를 통합 관리하고 거래 상대를 중개하는 중개 시스템에 대한 연구가 필요하다. 본 논문은 화주와 운송업체에게 거래 상대를 연계하는 물류정보 중개 시스템을 소개하고 중개 에이전트를 제안한다. 제안된 중개 에이전트는 화주와 운송업체의 요구사항을 가능한 만족하면서도 빠른 시간 내에 거래 상대를 찾기 위하여 휴리스틱 방법을 이용한다.

최근 물류 분야는 국가나 기업의 가치창출의 핵심동력으로 인식되고 있다. 하지만 내륙운송의 경우 정보화시스템의 현대화 및 정보연계는 미진한 실정이다. 국가물류의 효율화를 위해서는 물류흐름상의 정보 단절을 방지하는 것이 중요하며, 각 주체별 물류정보 연계/통합의 필요성이 확산되고 있다. 본 연구는 국가물류 효율화를 위해 각 물류 주체별 정보 현황 및 정보 통합의 문제점을 살펴보고, 물류 정보 표준화 방향성을 제시하고자 한다.

2000년 6월의 남북 정상회담과 동년 10월의 경의선 철도 복원을 위한 착공식을 계기로 남한과 북한은 실질적인 경제협력의 토대를 확고히 추진함과 함께, 화물 및 여객 수송에 대한 연계운행의 토대를 마련하고 있으며, 러시아는 이 기회에 서울-평양-원산-두만강-TSR로 이어지는 운송노선을 조기에 구축하고자 노력하고 있다. 그러나 이렇게 펼쳐지고 있는 정황 뒤에는 간과해서는 안될 기술적인 문제들이 있다. (중략)

Unsteady aerodynamic analysis of an air-pressure-levitated high-speed ground vehicle moving over the nonplanar ground surface are performed using the boundary-element method. The potential flow solution is included in a time-stepping loop and the wake is captured as part of the solution. When the vehicle moving inside the channel, the lift coefficient and the pitching moment coefficient of the vehicle are increased further because the air trapped by the channel increases the ground effect. In other words, the nonplanar ground surface such as the channel decreases further the longitudinal stability of the vehicle. On the other hand, there is little difference between the ground and the channel in the lateral stability of the vehicle because the lift increment due to the nonplanar ground surface such as the channel takes place on both sides of the wing with the same rate of increase.

The Northeast Asia has been the fastest growing region in the world for the past few decades. And now the economic bloc maintains its status as a major powerhouse of the world economy. On the way of its economic growth, Russia and Central Asian countries have emerged as major trading partners. The Trans-Siberian Railway(TSR) has been playing a pivotal role in promoting economic cooperation between the two regions. This paper investigates economic environment of the Korean TSR service operators through the SWOT analysis, then proposes management strategies for them. For this purpose, the authors analyze characteristics and roles of the TSR service operators. In addition, a comparison of difference between service operators and shippers about their recognition of economic environment of the TSR transportation service is also carried out.

Recently, the government of Russia has been cooperating with developed countries such as Germany, which have an advanced railroad system. They have been establishing a strategy to activate the Siberia Trans Railway. Thus, it is possible that a part of cargo will be transported by TSR (Trans Siberia Railway) instead of shipping. If there is a railroad system, connecting the North and the South Korea via the Busan port, a new freight route linking to Europe will be reached. This paper aim to investigate the intention of shipping companies, shipper, forwarders, who are prospective customers and/or competitors of TSR. An analysis of the competitiveness between TSR system and the waterway transportation will be also mentioned.

A rapid growth of interregional trade between China and Korea requires new development and expansion of ports. Currently, there is no rail-ferry system between China and Korea, however, a rapid growth of car-ferry industry shows possibilities. Several candidate cities and regions in East part of China and West part of Korea are selected. We identified times in clearance and station-to-station services as major benefits. We compared three transport modes including candidate cities and regions: container ships, car-ferry and rail-ferry. We used AHP (Analytic Hierarchy Process) as an evaluation method to select most competitive rail-ferry routes between two countries. We also used 7-point Likert scales to find out bottlenecks and factors to introduce rail-ferry services as other questionnaires. As a result, Rail Ferry System(RFS) is a little expensive due to wagon loading efficiency in cargo hold of the ship compared to Car Ferry System or Liner Shipping System. But RFS is recommendable in case of Block Train transport between Korea and EU area by may of TCR and TSR comparing Car Ferry System, because it can reduce total transport cost and connecting procedure at border lines of passing countries.

As the quantity of goods transported, port industry and inland transport industry have developing to transport 630million ton goods annually. And the inland transport industry consists of ground transport for almost 80% of total transported goods. But, ground transport causes some serious problems especially the emission of greenhouse gases from trucks. According to issue "global warming", many regulations and agreements with countries in the world are becoming necessary and it is being fulfilled now. It is sure that Korea will have duty to reduce CO2 emission from 2013. Thus inland transport must cut off CO2 emission level. Therefore this paper will address that the calculation of CO2 emission under route of transportation container from six major container ports in Korea. And then, it will predict CO2 emission of inland transport industry according to increasing container traffic rate at ports.

In recent years, the maritime industry system including port facilities, VTS(Vessel traffic service) is rapidly evolving with the development of technology. The connection between systems has been greatly expanded, and many research cases using this connectivity have been reported. This paper deals with the structural design of the arrival/departure support system for an autonomous ship. The system requires navigation data from the autonomous ship and radar/AIS data from the port. In this paper, design result on how the arrival/departure support system interacts with the autonomous ship and port system are addressed.

China is pushing a policy called China's Western Development in order to balance the continent's development level. They are connecting the rich natural resources of the mid-western areas and the capital of the eastern coastal areas of China. Since Korea depends on China the most for trade, it is necessary for Korea to always consider the trade scale and pattern changes of China. Response to changes in the transport and logistics system between the two countries is also demanded. This study aims to analyze the import and export trends between Korean and Chinese provinces of each item from the trade scale point of view. China's global trade routes reorganization and China's western development are considered and the corresponding direction is presented accordingly. The study also suggests strategies to expand the import and export scale with China based on the analysis.
