The purpose of this paper is to suggest a plan on promoting use of multimodal transport logistics terms in Incoterms, 2010. This study deals with the terms of three promotion factors which are a user's subjective factors, a trade transport logistics environment factors, and a term content factors. According to analysis results of the factors, a user's subjective factors(3.87 score) are scored the most ones of promotion factors of using multimodal transport logistics terms in Incoterms, 2010, to be compared with a trade transport logistics environment factors(3.60 score). with a term content factors(3.74 score). Therefore, first of all, it is important to promoting use of multimodal transport logistics terms in Incoterms, 2010 through as follows, a user's subjective factors : (1) to understand correlation of door to door multimodal transport and terms of Incoterms, 2010, (2) to promote use of multimodal transport logistics terms in Incoterms, 2010 in door to door multimodal transport, (3) to restrain customary use of FOB, CFR, CIF terms. And, the next, we have to promote use of multimodal transport logistics terms in Incoterms, 2010 through considering a trade transport logistics environment factors and a term content factors.

3자물류 시장의 급부상, 운송업계의 경쟁가열화, 운송경로의 다양화 및 글로벌화가 추구되면서 복합운송을 고려한 수송계획의 효율화가 필요한 실정이다. 본 연구에서는 국제물류에서 이루어지고 있는 복합운송을 고려한 최적수송계획 알고리즘을 제안하고자 한다. 화물과 경유지의 고려는 운송수단에 따라 동적으로 변화하는 NP-hard문제로써 가지치기 알고리즘(pruning algorithm)을 이용하여 문제를 단순화시키고, 운송수단을 제약조건으로 한 휴리스틱 최단경로 알고리즘을 제안하였다. 이를 부산항에서 로테르담항까지 실제로 사용되는 경로문제에 적용해 봄으로써 본 알고리즘의 효율성을 검증하였다.

As the development of Northeast Asian logistics hub becomes one of the national agenda for further development, the sea&Air transport around the Yellow Sea regions has drawn attention of many scholars and government officials. The Sea&air transport is a mode of transportation combining the advantage of high-speed in air transport with the advantage of low-price in sea transport. Hence the sea&air aims at a niche market between air and sea. This paper reviews the possibility of development of the sea&air transport in the aspects of competitiveness over other modes, future demand condition, and the change of the technology and transport environment. The result is that the sea&air is competitive in the aspect of time as well as cost, and sustainable in the aspect of future demand condition. But, it is not stable in the aspect of the conditions of technology or transport demand. Especially, the progress of air transport technology which is aiming at the door-to-door transport among mid- and small- cities, and the rapidly increasing strategic alliances of international airlines with Chinese airlines for the market of China will undermine the stability of the sea&air transport seriously As alternatives, this paper proposes the 3-stage development strategy of sea&air transport. First, at the stage of transshipement, the development of high speed vessels to reduce the time crossing the Yellow Sea and the proactive marketing strategy to induce Chinese-owned products should be emphasized. Second, the value added logistics activity which will secure the demand of the sea&air transport should be developed. Third, demand creation by developing the SCM hub in Incheon is final goal for the logistics hub strategy as well as the sea&air transport.

Recently, the transport quantity of goods between South and North Korea is rising rapidly by increasing of economical exchange between South and North Korea and growth of Gaeseoung industrial complex. In addition to a land transportation route, it is necessary to secure various logistics and transportation route for freight transportation between Incheon and Gaesung. In this paper, we investigated a construction of barge transportaion system between Incheon and Gaesung. The barge transportation system which has many merits such as a little initial investment and convenience of harbor loading/ unloading has been also used to transport freight widely in the EU and USA. Firstly, we investigated barge transport route, marine freight and barge fleet which consists of barge and pusher between Incheon and Gaesung. And next, we designed hull form and general arrangement of a barge and pusher based on shipping service condition, barge fleet, etc. Finally, a construction plans of barge transport system such as a operation of shipping service, berthing facilities, logistics center, intermodal transport are investigated.

China has recently advocated a national strategy called "One Belt One Road" and transferred to execution to refine it into detailed action plans and has continued to fix the complement. However, the Korean Peninsula, including the North Korea remains could not be included at all in the Chinese development policy and framework in terms of the International Logistics. Currently it is raised between Korea-China rail ferry system again and that is when we need to make effective policy development on international multimodal transport system in Northeast Asia. This paper introduces the K-LB (Korea LandBridge) as its execution plan and conducted a feasibility study on this. K-LB consists of a Korea-Russian train ferry system based in Pohang Yeongil New Port(light-wing) and a Korea-China train ferry system based in Saemangeum New Port(left-wing). These two wings are linked to the existing rail system in Korea. This study is convinced that the K-LB is an effective international logistics system in the current terms and conditions and also demonstrated that it is feasible to introduce th K-LB on the peninsula. More strictly speaking, through a linear programming under objective function that minimize the transport cost quantified prior to demonstrate the feasibility, the available ranges and conditions for the transportation costs that are ensured the effectiveness of the K-LB are presented as results. According to the results, if the transport cost of K-LB is cheaper about 34.5% than that of sea transport such as container transport, the object goods may be transported by K-LB on this route. It means that the K-LB system has a competitive advantage due to more rapid customs clearance as well as omitted loading and unloading procedures over container transportation system. It also noted that the threshold level may not be large. Therefore, K-LB has competitive enough to prove its introduction in the Northeast Asian logistics system.

The railway is widely used to transport passengers and freight due to its punctuality and large transport capacity. The recent remarkable development in construction technology enables various subsea railway tunnels for continent-continent or continent-island connectivity. In Korea, design and construction experience is primarily based on the successful completion of the Boryeong subsea tunnel (2021) and the Gadeok subsea tunnel (2010). However, frequent earthquakes with diverse magnitudes, globally induced and continuously increased the awareness of seismic risks and the frequency of domestic earthquakes. The effect of an earthquake on the subsea tunnel is very complicated. However, ground conditions and seismic waves are considered the main factors. This study simulated four ground types of 3-dimensional numerical models, such as soil, rock, composite, and fractured zone, to analyze the effect of ground type and seismic wave. A virtual subsea railway shield tunnel considering external water pressure was modeled. Further, three different seismic waves with long-term, short-term, and both periods were studied. The dynamic analyses by finite difference method were performed to investigate the displacement and stress characteristics. Consequently, the long-term period wave exhibited a predominant lateral displacement response in soil and the short-term period wave in rock. The artificial wave, which had both periodic characteristics, demonstrated predominant in the fractured zone. The effect of an earthquake is more noticeable in the stress of the tunnel segment than in displacement because of confining effect of ground and structural elements in the shield tunnel.
