This paper studies a periodic review inventory model with an e-MarketPlace transaction in reconfigurable manufacturing system(RMS). A decision maker can expand/reduce production capacity/quantities and/or replenish/dispose inventories from/to e-MarketPlace urgently to satisfy the stochastic demands. If inventories are replenished or disposed through e-MarketPlace, this leadtime is shorter than the production leadtime, but unit purchasing or selling cost is more expensive than that of expanding capacity or reducing production quantities respectively. Henceforth, trade-off on these alternatives is considered. In addition to this, in order to consider the economy of scale, our model includes the fixed cost for purchasing from e-MarketPlace and capacity expansion. We use dynamic programming and K convexity methods to characterize the nature of the optimal policy. Finally, We present the optimal inventory control policy which is composed by the combinations of a base stock and (s,S) type policy.

Internet-based electronic trade has been growing fast. But most users are not yet familiar with the system and find it very difficult to purchase and sell the products in the cyber market place. To handle these problems, agent-based virtual market place system has been proposed where agents instead of individuals participate in trading of goods. Most of the proposed models have been in the two general categories. The first is the direct transaction among sellers and buyers, and the second is the agent-based transaction. However, the transaction is not fair and the best deal can't be guaranteed for both models. In this paper, we propose a new broker based synchronous transaction algorithm which is fair to both parties and guarantees the best deal. Our algorithm is implemented using Visual C++ and the experimental results show that our method is better than the two traditional transaction models in every performance metrics, Number of transactions are increased up to 21% and price adjustment is up to 280% better for some transactions.

It has been talked about the responsibility of the South-North Korean e-market place(e-MP) collaboration project every you since 2003. However, the feasibility as the business has not been dealt with in detail due to the uncertain environment as well as the complicated procedures of the project. The research focuses on the workable mechanism of the South-North Korean E-Market Place collaboration project. The feasibility of the project results from the newly installed fiber telecommunication network as well as the 1 billion dollars of the trading volume between South and North Korea. The research analyzes on the capabilities as well as willingness of the South and North Korea for the e-MP, and concludes with two paradigms of the future tasks. First, the unified but step-wise structure should be made to promote the project by the political committee (South and North Korea EC Committee) and the economical administration body (South and North Korea EC Corporation). Second, the market-oriented resolution system such as South and North Korea Arbitration Body should be involved to create legal environment. Above all, the discussion should be on the main body of e-MP settlement to abolish the psychological as well as practical barriers to enter the South-North Korean electronic commerce.

Due to the changes in market place, new business types(e.g. e-business} have been rapidly emerged and increased. However, those new business types have not much been emerged in port and logistics related industries, and adoption rate of e-business in this area is very low, compared to other industries. Thus, to promote e-business in this area, many policies have been studied. However, most of previous studies have not been based on industrial structure, and results of these studies have mostly been case by case. Further, there have been no research based on the related theories. As a result, despite many of research and project for shipping and port related e-business, prominent achievements in this area have never to be presented. For these reasons, it am be stated that, first of all, basic studies related to new business types in shipping and port are needed, and then, various policies based on results of those basic studies should be discussed. The aim of this study is to classify business types existed (or expected) in a port related industry, ship bunkering. This taxonomy was based on theories related to business layer(BL) and value chain(VC), and these BL and VC combination enabled to acquire all possible business types.

The main objective of this study is to examine the mediating effect of 'e-trust' on the relationship between the antecedents related to e-marketplace and the intention of using e-marketplace. Data was collected from a survey of 169 exporting firms in Gwangju, Korea. The results of the study are as follows ; First, 'e-trust' is produced a mediating effect when technology and government factors affect the intention of using e-marketplace. However, "e-trust" does not play a mediating role in the relationship between company factor and the intention of using e-marketplace. Second, technology factor, government factor and company factor have a positive impacts on the intention of using e-marketplace. Accordingly, in order to enhance the intention of using e-marketplace, small & medium exporting firms in Korea should try more to prepare for factors related to technology and company. In addition to these, government should give full support to be prepared for regulations and systems related to e-marketplace. If e-trust were properly built, the enhancement of using e-marketplace would be taken place more smoothly. So most of exporting firms can participate in e-marketplace more actively.

The purpose of this study was to identify the current situation of textiles and apparel firms in the overseas markets and to examine the relationship between firms' characteristic(i.e., sales volume) and international marketing strategies. A random sample of 311 textiles and apparel firms were selected. The survey design method was used to test conceptual framework. Adjusted response rate was 33.4%(n=115). Descriptive analysis (i.e., frequency, percent) and $\chi$$^2$-test were used for data analysis. About the current situation of textiles and apparel firms in the overseas markets, the motivation for international market entry was highly found to expand their operation from domestic to international market, and most firms were found to be involved with OEMs(Original Equipment Manufacturers) as an entry mode for international market. China and US market were the most popular market among Korean textiles and apparel firms. Product differentiation strategy, pricing strategy based on manufacturing cost and buyer's offering price, place strategy using foreign buyers and participating a few international exhibition were frequently used among Korean textiles and apparel firms for international marketing. Among textile firms, sales volume was related to product strategies(product development), price strategy(buyer's offer) and place strategy(channel). Among apparel firms, product strategy(product labeling), price strategy(price satisfaction). The findings of this can be used when Korean textiles and apparel firms do strategic planning and evaluate the international marketing strategies. Also information and results of this study may assist policy makers to develop better ideas and strategies for textiles and apparel industry.
