The purpose of this research is to suggest a desirable framework to promote EDI system in the Korean trade and transportation industries. First, this thesis reviews the trend of introduction of EDI systems in foreign countries and investigates their characteristics by examining some cases. Then the problems, which the Korean industries would be confronted with during the course of introduction of EDI system, are identified and discussed. Finally, this thesis suggests that the logistics network should be developed as a main system of EDI to which sub-networks of trade and custom service are linked. This leading role of logistics metwork is necessary to the EDI system because logistics tasks for international movement of goods are expected to increase while tasks related to trade and custom services will decrease in view of recent changes in the world trade environments warning the unbounded competition in the global marketplace without border.

In the quality planning phase, the techniques for measuring cost-quality trade-offs are used for the selection of the optimal design specifications when design flexibility permits significant trade-offs to be made. But the product quality is not only depends on the developing cost, but also the time for developing that product. Therefor it is important to seek a methodology for estimating time-cost-quality trade-offs associated with the quality planning projects. This paper is aimed to find a methodology of time-cost-quality trade-offs and to develop a proper algorithm.

In a project schedule, it is possible to reduce the time required to complete a project by allocating extra resources for critical activities. However, accelerating a project causes additional expense. This issue is addressed by finding optimal set of time-cost alternatives and is known as the time-cost trade-off problem in the literature. The aim of this study is to identify the optimal set of time-cost alternatives using a multiobjective teaching-learning-based optimization (TLBO) algorithm integrated with the non-dominated sorting concept and is applied to successfully optimize the projects ranging from a small to medium large projects. Numerical simulations indicate that the utilized model searches and identifies optimal / near optimal trade-offs between project time and cost in construction engineering and management. Therefore, it is concluded that the developed TLBO-based multiobjective approach offers satisfactorily solutions for time-cost trade-off optimization problems.

The Kaes$\breve{o}$ng Industrial Park(KIP) is being developed in the region, as a collaborative economic development with South Korea. KIP construction started in June 2003, and in August 2003 North and South Korea ratified four tax and accountancy agreements to support investment. Pilot phase construction was completed in june 2004, and the KIP opened in December 2004. In the KIP's initial phase, 15 South Korean companies constructed manufacturing facilities. Three of the companies had started operations by march 2005. First phase plans envisaged participation by 250 South Korean companies from 2006, employing 100,000 people by 2007. Based on the 2009, 117 factories were employing approximately 41,000 north' workers and 1,000 south' staff. The industrial park is seen as a way for South Korean companies to employ cheap labour that is educated, skilled and speaks Korean which would make communication considerably easier. However the zone still faces a number of obstacles. In the view point of these obstacles, especially this study focused on the complementary issues for the improvement of trade goods management systems between South and North Korea. At the result of this study, it is suggested that, i) to establish portal system based on single window, ii) strengthen user-interface hands of logistic facilities, iii) stable foundations of trade and/or logistic management systems, iv) networking of IT infrastructure with South and North Korea, and so on.

The purpose of this paper is output oriented, in order to maximize the output level of sustainable development efficiency of foreign trade in western China with limited input. This paper adopts the relevant input-output indicators of sustainable foreign trade development of 11 provinces and cities in western China from 2016 to 2020, and uses DEA model to measure their technical efficiency, pure technical efficiency and scale efficiency. Malmquist index was used to calculate the total factor productivity change index of each province in western China from 2016 to 2020. We found that, on the whole, the average values of technical efficiency, pure technical efficiency and scale efficiency of provinces and cities in western China from 2016 to 2020 are greater than 0.8, indicating that the western region has high technical efficiency, relatively high management and institutional level and high existing scale level. Scale efficiency is lower than pure technical efficiency on the whole, indicating that the current sustainable development efficiency of foreign trade in western China is mainly limited by its scale level. The technological progress index is higher than the technological efficiency change index, indicating that the total factor productivity of the sustainable development of foreign trade in western China is mainly driven by technological progress and more influenced by external factors. We think the conclusion of this study can provide important reference information for the sustainable development of foreign trade of provinces and cities in western China.

This study investigated the effects of values towards Korea fair trade coffee consumers upon attitudes and behavioral intentions and verified the moderating effects of ethical consumption consciousness between relationships among values, attitudes and behavioral intentions. A total of 283 data were analyzed for consumers of fair trade coffee residing in Seoul. Structural equation models were used to identify the relationship between the variables. As a result of the analysis, Schwartz (1994)'s 30 value items were factored into four areas: openness to change, self-enhancement, conservation, and self-transcendence. The value of 'self-transcendence' showed a significant positive impact on attitudes toward fair trade coffee, whereas 'openness to change' had a significant negative impact. Positive attitude toward fair trade coffee showed a significant impact on intentions to buy fair trade coffee. In addition, a moderating effect of ethical consumption consciousness between attitude and behavioral intention was found. Limitations and future research directions are also discussed.

Recently open data has been spread rapidly in the world include Korea. Accordingly in international trade field open data and using it became a key point to get competitiveness. In this study, the author make an attempt to suggest the way for quality improvement of international trade information by looking for some problems with crating and using the information. Thus, the problems of using information are can be point out as follows. Firstly the range of open data is narrow. Secondly the management of the open data is not conducted properly. Thirdly the suppliers of the open data didn't prepare some investigation system for their data's usability for user. Expansion of the organizations who open data is one way to solve quantitative problem. There are four suggestions to solve qualitative problems. Firstly the guidelines should be established and operated in each organizations respectively. Secondly the criterion of expenses for open data should be arranged among the concerned parties. Thirdly the ability of the manpower and organization who charged in the quality improvement of information should be reinforced both quantitatively and qualitatively. Lastly the system for data usability for user should be equipped in early stages. Finally the author emphasize the establishment of total management system for using open data in international trade is not needed only the efforts of the specific parties but also all parties led by Ministry of Industry, Trade and Energy in order to carry out above suggestions successfully.

In this study, AHP analysis was conducted through a survey that was organized by 9 job categories. The results show that sustainable operation risks have the highest priority level among all criteria with management interest having the highest priority level within sustainable operation risks related attributes. The most important risk attributes among stakeholder risks appeared to be asset security and cargo and conveyance security, with education and training being the most important among regulatory risks. Effective management and response to the risks from export controls on strategic trade require an understanding of supply chain security and compliance programs, effective training programs, investments for development of security systems that meet international standards. In addition, the government needs to focus on developing professionals and providing support for companies with compliance programs, working closely with businesses.
