In a competitive and globalized business environment, the need for the green products becomes stronger. To meet these trends, the environmental assessment besides delivery, cost and quality of products should be considered as an important factor in new product development phase. In this paper. a knowledge-based approximate life cycle assessment system (KALCAS) for the collaborative design environment is developed to assess the environmental impacts in context of product concept development. It aims at improving the environmental efficiency of the product using artificial neural networks consisting of high-level product attributes and LCA results. The overall framework of the collaborative environment including KALCAS is proposed. This architecture uses the CO environment to allow users on a wide variety of platforms to access the product data and other related information. It enables us to trade-off the evaluation results between the objectives of the product development including the approximate environmental assessment in the collaborative design environment.

This study investigates the dynamic effects of economic development, international cooperation, electricity consumption, and political risk on the escalation of CO₂ emission in Vietnam. We adopted autoregressive distributed lag model and Granger causality method to examine the interaction between CO₂ and various economic and political factors, including foreign direct investment, trade openness, economic growth, manufacture, electricity consumption, and political risk in Vietnam since the economic revolution in 1986. The findings reflect opposite influence between these factors and the level of CO₂ in the intermediate and long-term durations. Accordingly, foreign direct investment and CO₂ emission have a bidirectional relationship, in which foreign direct investment accelerates short-term CO₂ emission, but reduces it in the long run through an interactive mechanism. Moreover, economic development increases the volume of CO₂ emission in both short and long run. There was also evidence that political risk has a negative effect on the environment. Overall, the findings confirm lasting negative environmental effects of economic growth, trade liberalization, and increased electricity consumption. These factors, with Granger causality, mutually affect the escalation of CO₂ in Vietnam. In order to control the level of CO₂, more efforts are required to improve administrative transparency, attract high-quality foreign investment, and decouple the environment from economic development.

Korea is facing great threat from other countries as a major global sourcing site for textile and apparel products. The threat has been augmented by changes in external environment such as advents of Trading Blocs and Free Trade Area(FTA) as well as internal environment such as hikes in labor cost and lack of flexibility in accommodating international buyers' needs. This study analyzed international buyers' sourcing activities in Korea for the purpose of developing strategies to enhance competitiveness of the Korean textile and apparel industries in the global market. The data used in this study were gathered by surveying 52 non-Korean textile and apparel product buyers with cooperation of the Korea Federation of Textile Industries (KOFOTI). The data were analyzed by mean, frequency, Pearson correlation coefficient, and ｘ$^2$ analysis. The results indicated that Korea is still attractive to many international buyers especially to those who have been engaged in global sourcing for longer periods of time with bigger purchasing budgets. However, in order to expand and solidify their customer bases, Korean companies should focus more on developing competitively priced value added products a step ahead of their foreign competitors, diversifying their marketing channels including internet.

The world is now meeting the era of e-commerce by development of information technology and the fast increase of use of internet. So, Korean government prepared "the colligation plan for electronic commerce activating" and WTO decides to prolong no custom on e-commerce till November 2001 when the fourth WTO Ministerial Conference holds a meeting. OECD discussed the construction of intellectual property rights of the global dimension at the Global Forum on January 2001 and reached to research the social influence of B-to-B e-commerce and to pursue the acceleration of e-commerce. UNCITRAL(United Nations Commission on International Trade Law) enacted UNCITRAL Model Law on Electronic Commerce in order to activate e-commerce, and Bolero.net serves electronic Bill of Lading to facilitate cyber trading. The purpose of this paper is to present the direction of confrontation to the these internal and external changes of business environment to Korean enterprises. Off-line enterprises should move fast to e-commerce on the condition that the existing trading at the original markets runs parallel with e-commerce. n needed, off-line enterprises should consider M&A with existing on-line firms. Also, off-line firms make use of Bolero system so that they can carry through paperless trade which means the achievement of efficiency in trading, On-line enterprises should advertise in the form of banner by combination of push and pull styles. B-to-B e-commerce firms should not depend on only the commissions, but they should create characteristic earnings by their peculiar services.

Purpose: This paper examines the theoretical grounds for the disclosure of the Korea Fair Trade Commission. Three central measures of the disclosure are scrutinized: The interconnected status of affiliate companies, the important matters of private affiliates, and the large internal transactions. Contemplating on three measures, respectively, we review the rationale and derive policy implications. Research design, data, and methodology: Collecting the data of violation rates and remedial measures, we analyze the intensity of the disclosure enforcement. These statistics are critically reviewed by the economic literature of mandatory disclosure. Results: Statistics evince that the Korea Fair Trade Commission has enforced the regulatory disclosure quite successfully. Violation rates of the disclosure has declined from the outset. It demonstrates that the Korea Fair Trade Commission has enforced those measures satisfactorily for about a decade. But we cannot ascertain empirically whether the regulatory disclosures are socially and economically beneficial. To evaluate the effect of the regulatory disclosures precisely, we need a further empirical investigation. Conclusions: Despite the lack of policy evaluation, this study suggests complementary measures for current disclosures. First, disclosure of executive compensation in privately held subsidiaries must be introduced. Second, the controlling shareholder/manager should be responsible for information disclosure on foreign subsidiaries.

This research examined the mediation effect of Workforce Agility (WA) on the relationship between environmental uncertainty and operational performance. We manipulated the control variables that are known to be affected by employment flexibility. Employment flexibility is caused by idiosyncratic characteristics of Korean port system. The analysis was tested by Baron & Kenny's method. The result indicates that each path of the proposed model is significant. Furthermore, the mediation effect was checked with the Sobel Test. The research revealed that environment uncertainty poses an indirect effect on operational performance. Both supply/demand uncertainty and technological uncertainty affected operational performance through the mediation effect of WA. Most of the distribution centers located in Busan Newport Distripark are operated in a bimodal labor (human resource) system which includes both permanent employees (workers) and temporary employees (workers). This empirical research provides theoretical and managerial implications by suggesting ways to increase efficiency in distribution center operation through WA enhancement, and to improve the unloading labor system.

As Korea's steel industry exports 38 percent of its total steel production, the future management environment of the steel industry will change depending on the outcome of the FTA negotiations. The overall industrial structure of the domestic steel industry depends on the rules of origin, which are directly linked to the effect of concessionary tariffs. Therefore, negotiations on rules of origin are as important as tariff liberalization for Korea's steel industry. Korea's cold-rolled and plated companies are expected to be negatively affected as the country of origin standards of steel products have not considered the steel production processes in Korea. In future FTA talks, the country of origin rules should be agreed on a change of tariff classification basis. This result would secure a stable export market through increased predictability of steelmakers and reduce the risk of increased costs of oil and intangible products. In addition, the government should consider the structure of domestic supply and demand so that it does not impose constraints on the change of tariff classification. Finally, participants in the negotiations should consider the opinions of the domestic steel industry.
