INCOTERMS have been changed almost every 10 years since ICC established INCOTERMS as trade terms for International transaction. Recently transportation has become bigger, and modernized by means of electronic appliances such as RFID, IT, and containerization. FRC, FOR/FOT, FOA were added in INCOTERMS1980 and every conditions are unified into three alphabets in INCOTERMS1990. The best features of INCOTERMS2000 are that FCA substitute FRC, FOR/FOT, FOA and customs formalities were simplified to make clear for each party of contract. It seems that business circles still stick to old customs of their trade like FOB or CIF not only in Korea but in an international practice even though there have been several revisions of INCOTERMS until now. ICC have tried to provide INCOTERMS3000 to solve problems between a theory and an actual condition of international trade. This study has tried to suggest opinions against INCOTERMS3000 and has surveyed a recognition, an actual using situation and issues of INCOTERMS to get improvements. For a recognition of INCOTERMS has been spread as you can find at tables many kinds of business circles still stick to old customs of their trade terms FOB and CIF. Now there are two alternative plans. Firstly, we need to suggest improvements against inconsistency of INCOTERMS to be applied on newly revised INCOTERMS3000 and educating business circles to use proper conditions of INCOTERMS for their doing business. Secondly, we shall participate in revising INCOTERMS to activate multimodal transport conditions of INCOTERMS and provide solutions to fill gap between a theory and an actual condition of international trade. It seems that terms of multimodal transport such as FCA, CPT, or CIP can be a perfect condition for each party of contract. We have examined the inconsistent features of Ship's rail and notions of on board, and observed how to activate multimodal transport terms. These would be hot issues of next revision of INCOTERMS and we provided improvements on each trade terms, THC charges, or others against INCOTERMS.

This study aimed to identify new routes for transporting automobiles from Korea to Mongolia by comparing them with the existing route. At present, a route from the Incheon Port through the Tianjin Port to Zamiin-Uud is commonly used to transport containerized cargo from Korea to Mongolia. This study examined five possible logistics routes from Korea to Mongolia using a time/cost-distance methodology based on real data. Through consecutive discussions with importers and freight forwarders in Mongolia, the potential routes were selected and costs, distance, and lead time were evaluated to provide additional route options for automobile logistics from Korea to Mongolia. The results indicated that each route could be ranked in terms of the total cost while the lead time for all options in the present COVID-19 period is 2 - 4 months, with no difference among the routes. In addition, although the confidence index of all routes was not impressive, route 3 was the most preferred option, followed by route 1. However, the study results cannot provide the answer to the question of "which route is more attractive for transporting automobiles from Korea to Mongolia." This limitation notwithstanding, this study provides real information on the critical factors of distance, cost, and lead time in terms of the selected transportation routes so that importers and exporters can compare the routes in terms of the priority of each factor in uncertain logistics environment.

이 연구는 우리나라에서 현재까지 사용되어 온 (수단O/D기반)화물수요추정법의 문제점 인식을 바탕으로 P/C기반 화물수요추정법과 비교 분석을 수행하였다. 우리나라 화물수단O/D는 화물의 최초기점과 최종종점 간 운송을 수단별 통행으로 나누어 인식하면서 접근트럭통행(Access/Egress Truck Trip)에 대한 정보가 누락되어있다. 이러한 이유로 수단O/D기반 화물수요추정법은 화물의 복합수단운송을 반영하지 못하는 단점이 있다. 이에, 본 연구는 우리나라 컨테이너 화물을 중심으로 P/C표와 복합수단선택모형을 추정하여 P/C기반 화물수요추정법을 제시하고, 기존 사용되어 오던 수단O/D기반 화물수요추정법과 기종점쌍 간 전환량, 수단통행물동량, 링크물동량을 비교하였다. 비교 결과 P/C기반 화물수요추정법은 복합운송을 제대로 모사하지 못하는 기존 수단O/D기반 화물수요추정법의 문제점을 해결할 수 있는 것으로 평가되었다.

Purpose - As economic activities between different countries have rapidly spread in a world of free trade, it is inevitable that a large volume of cargo will be carried between countries. It is natural, then, that CO2 emissions and other environmental pollutions have followed, which exposes people and society to serious environmental problems and social costs, and so on. Therefore, the need to understand logistics is not only a matter of transportation but also an environmentally oriented matter. The purpose of this study is to look at some lessons and implications from the European case in terms of green logistics matters. Research design, data, and methodology - In order to look into this matter, first, it has to be established that some cargo transport volumes using different transportation modes have clearly declined because of previous economic recessions. Some transport policies produced by the European Union (EU) are based in a long history of struggling to cope with transport matters in European countries. In its recent transport policies, the EU has provided greener transportation alternatives, realizing that pollution matters affect the European transport market. This study tries to determine what policies the EU has implemented to deal with green logistics matters. This study concentrates in particular on the Marco Polo program in the EU. Results - This study found that the EU seems to consider these kinds of matters, that is, transport and the environment in the context of green logistics. The EU launched some policy instruments to solve this matter relatively earlier than other countries and reviewed them as necessary. In order to make these policy tools work, the EU provided PACT for combined transport, and then the Marco Polo I and II European transport white paper packages. These European policies deal with green logistics matters in two ways. First, some restrictions have been imposed, especially taxation, and so on. Transport subsidies are also powerful means of handling green logistics matters in Europe. Along with these two means of dealing with transport and the environment, the EU eventually targeted integration of different transport modes. Instead of employing only a single transport instrument mode to deliver the cargo to be carried, such as trucking, rail, ocean-going carrier, flight, or inland waterway transport, the EU has proposed that combining transport modes is the best alternative for transport and the environment. That is, the EU is pursuing the adoption of multimodalism as an answer to the green logistics challenge as it provides a more cost efficient and more productive means of transport. Conclusions - In conclusion, multimodal transport should be considered when applying green logistics, as it can provide an alternative way to achieve transport and environmental solutions together at the present time. Two methods can be used to encourage multimodal transport: restrictions and subsidies. These are the lessons and implications from European green logistics policies.

Due to the significant increase in the use of autonomous car technology, it is essential to integrate this technology with high-precision digital map data containing more precise and accurate roadway information, as compared to existing conventional map resources, to ensure the safety of self-driving operations. While existing map technologies may assist vehicles in identifying their locations via Global Positioning System, it is however difficult to update the environmental changes of roadways in these maps. Roadway vision algorithms can be useful for building autonomous vehicles that can avoid accidents and detect real-time location changes. We incorporate a hybrid architectural design that combines unsupervised classification of vision data with supervised joint fusion classification to achieve a better noise-resistant algorithm. We identify, via a deep learning approach, an intelligent hybrid fusion algorithm for fusing multimodal vision feature data for roadway classifications and characterize its improvement in accuracy over unsupervised identifications using image processing and supervised vision classifiers. We analyzed over 93,000 vision frame data collected from a test vehicle in real roadways. The performance indicators of the proposed hybrid fusion algorithm are successfully evaluated for the generation of roadway digital maps for autonomous vehicles, with a recall of 0.94, precision of 0.96, and accuracy of 0.92.
