China has increased 10 percent every year since 1978. In particular, development and growth of Chinese ports make a remarkable in that the marine and coastal transportation handles the 90 percent of export-import cargo. This growth is beginning to threaten Korea's ports which are striving to become the hub of Northeast Asia logistics. Furthermore, the hub strategy of Northeast Asia is closely related to transshipment cargo invitation. The results of documents research indicate Busan and Gwangyang ports play an important role as an intermediate stopover between China and America. The ways to achieve transshipment cargo invitation are the construction of transshipment system based on the supply chain between korea and china, the maximization of trading volumes creation, equipment of ports infrastructure, and the constructions of the rail, road, coastal transportation infrastructures.

With increasing uncertainty of energy market in the world, the policies for the energy resource security have become crucial Several countries with poor energy resource like Netherlands and Singapore have pursued the policy for becoming an oil hub in the region. Singapore has been an oil hub in East Asia for a long time not only because it is well located with a large number of countries exporting and importing oil but it has also pursued strong policies to become an oil hub while establishing favourable institutional, regulatory and business environment for accommodating major refineries and petro-chemical companies. However with growing trading volume of petroleum products in Northeast Asia and a record high price of oil in these days, the necessities of another oil hub in the region are considered in order to reap benefits of the security of economical and stable oil. South Korea is situated astride the main North Pacific shipping route, with deep water ports and proximity to Chinese and Japanese industrial centres that make tank terminal operators Ideal choices for the oil hub in Northeast Asia although it has several disadvantages such as lack of independent storage facilities, underdeveloped oil trading market and unfavourable business friendly climates etc. This study is focused on examining the globalization strategies of tank terminal operators such as Vopak, Oiltanking and Odfjell in order to suggest the policy implications for becoming an oil tub in Northeast Asia.

This study aims to develop the research model about the factors that have impact on uTradeHub users' acceptance and resistance to innovation. The followings show the research hypotheses and the results of test. i) The result of H1 empirical analysis confirmed that relative advantage and task adaptedness of e-Trade have more impact on acceptance of innovation than on resistance to it. And also perceived risk and complicity of e-Trade have more impact on resistance of innovation than on acceptance to it. ii) The result of H2 analysis confirmed that the characteristics of foreign trading companies (support by CEO and IT infra maturity) has more impact on acceptance of innovation than on resistance to it. iii) The result of H3 analysis confirmed that characteristics of uTradeHub user' resistance has more impact on resistance of innovation than on acceptance to it. And also, it was confirmed that acceptance of innovation has more impact on the diffusion of e-Trade than resistance to innovation. iv) The result of H4 analysis confirmed that the difference of the degree and factors that has impact on the user's resistance and acceptance by adoption stage of e-Trade. This study has significance in that it arranges the concept and stages of e-Trade systematically and, unlike other studies, it goes beyond the acceptance and diffusion of e-Trade to the inclusion of resistance together in the model.

This study proposes and verifies an integrated model that reflects and helps to explain complexities and comprehensiveness of e-Trade in practice. The primary objective was to widen and deepen our understanding about the phenomena of paperless trading which will enable us to formulate an effective means to promote the adoption and utilization of e-Trade infrastructure. This investigation combined and extended the theories and models of TAM, TOE framework, and TTF in order to identify and hypothesize the causal relationships between factors of technology, organization and environment, and the usage level and performance of e-Trade. The previous research on e-Trade was reviewed and incorporated into the extended model. The integrated model was tested based on the survey data collected from a sample of 417 trading firms. Overall, the regression and path analysis demonstrated the usefulness of the proposed model as a conceptual framework for better understanding and explanation of e-Trade. The result of the analysis implies the relevancy of the factors of technology, organization and environment for facilitating usage of and increasing performance of e-Trade. However, rejection of a few hypothesized relationships implies the necessity of extensive promotion and education about the related laws and regulations, and education, supervision and incentives for e-Trade practitioners.

Purpose - The Visegrád Group cooperation of the past 14 years and that of V4 for the past 20 years has very important significance in the 21st century that must be maintained. This cooperation is valuable because of the trade routes that connect northern Poland to the Balkans in southern Croatia, which forman important basis for the resuscitation of Central European development. Currently, because of the European manufacturing base and industrial development, an energy supply and stable energy distribution networks have been introduced to secure cooperation and not competition within the Visegrád Group. This paper's research emphasizes the supply chain hub in neighboring countries. Although Central and Eastern European countries are small, they can provide a competitive response to Western Europe if they collaborate with the V4 group and other countries. Research design, data, and methodology - The subjects of this study in the Visegrád Group area are related to the development of Marketing and Distribution Sciences in the integrated European Union. In relation to the existing energy infrastructure, construction companies and financial institutions benefit from large-scale construction projects. Existing or new infrastructure facilities among the V4 must comply with the preconditions of regional energy markets. The network of emerging markets is changing into a European-logistics hub of new markets. This hub is closely associated with the economic development of European self-sustainment given that energy for distribution and consumption is imported from Russia. Therefore, this paper indirectly provides data on the regional distribution of energy as alternative bases in Europe for market expansion to Asia. Results - As a result, it appeared unlikely that V4 failed to implement homogeneity following the standards of Western Europe, as proposed by the EU. Throughout European history, individuals have gathered in Central Europe as an innovation hub. Currently, the region is being established independently for energy industrial development and not for tourism development, and is expected to play a central role in innovation and distribution consumption. Therefore, similar to Western and Northern Europe, V4 only appears to engage in distribution consumption on the basis of the identity that it formed for itself. This area is expected to either create a regional platform or a voice over a single economic policy. Conclusions - To this end, regarding the distribution of consumer groups within and outside the region, the V4 group is expected to be established for various policy areas and as a Eurasian outpost of trade and distribution logistics. In addition, given its purpose of engaging in the distribution of energy cooperation and trade clusters, the Visegrád Group will be in charge of the center axis of the bridge for distribution logistics trading partners from the Western Balkans to Caucasus and Eastern Europe. Thus, the Visegrád Group is entering this region as a platform for market share by enabling all or any investor can gain greater industrial benefits.
