In this paper we analyze the effects of loading-unloading environments on the efficiency of freight railroad stations using a two-stage procedure for efficiency model estimation. And from the results we explore a way for efficiency improvement of freight railroad stations. Two-stage procedure is composed of data envelopment analysis and regression analysis. The results show that we could expect efficiency improvement through the government"s effort to make railway stations to be strategic position. Furthermore, they advocate policy-makers that efficiency can be improved by simplifying the kinds of freight items and increasing the scale.

The objective of this paper is to develop a stochastic inventory system model under the so-called continuous-review policy with a Poisson one-at-a-time demand process, iid customer inter-arrival times {Xi}, backorders allowed, and constant procurement lead time $\gamma$. The distributions of the so-called inventory position process {$IP_{(t-r)}$} and lead time demand process {$D_{(t-r,t)}$} are formulated in terms of cumulative demand by time t, {$N_t$}. Then, for the long-run expected average annual inventory cost expression, the "ensemble" average is estimated, where the cost variations for stock ordering, holding and backorders are considered stationary.

This study aims at surveying the current competitive position of our construction machinery industry in the international market. We will then reveal the critical issues by applying a SWOT analysis and a Delphi research from the viewpoint of strategic planning. At the same time, policy alternatives are also sought after as contributory tools to resolve the strategic issues demonstrated in this analysis and research.

This paper aims at analyzing the issues on how to improve UNEP's roles in international environmental governance context. Although UNEP has been presumed to play a leading role in addressing global environment problems, several problems (such as collective action problem, fragmentation, lack of authority and insufficient legitimacy) in its governance have led to losing its leadership to other entities such as the World Bank, OECD and CSD. While a position of changing UNEP's status to an independent international organization has not been developed enough, several efforts, which might not be sufficient to respond to the changing environment of international environmental governance, have been made to strengthen UNEP's roles in the short run. These include universal membership, strengthening the financing of UNEP, and issues concerning MEAs. Whether current efforts for enhancing UNEP's roles in international environmental governance will be successful or not, would rely on to what extent interested parties hold political wills for its reforms and how to draw a compromise on critical issues among those parties.

Currently, container transport services play a substantial role in global cargo transportation, by serving as an intermodal between exporter and importer. Container shipping has become increasingly important over the past few decades, due to obvious advantages. However, Vietnam's container market has shown severely ongoing competition among numerous domestic and foreign shipping lines, resulting in serious consequences occurring such as freight rates substantially decreasing within the last 10 years. Vietnam's sea lanes have become more defensive, to cover losses of shipping companies. Selection of criteria for competitive evaluation of container transport companies is necessary, to facilitate addressing the problems within the enterprise, especially relating to its position in the market and from here, business management can implement strategic plans and reasonable policy, to survive and grow.

Recent development of Taiwanese IT industry is one of the under-researched areas compared to their rapid development for last few decades. Especially Taiwanese IT industry has position themselves as leading technological power through cooperation with mainland China. For Korean IT industry, in order to compete against Taiwanese IT corporations, more researches need to be done how Taiwanese IT industry has evolved over the years. This research has analysed that Taiwanese IT industry has developed by specializing in OEM/ODM and nurturing small-medium sized corporations. Also the research describes the rold of government nurturing small/meduim sized IT companies and how effectively technologies are transferred to those companies.

Since 1979, the People's Republic of China has been opeining their marke tprogressively toward all over the world for developing its own domestic economy and international trade. China also has paid a great attention to the international maritime transport due to the fact that its volume of international trade has increased continuoulsy. Under such circumstance, the Chinese Maritime Code was issued in 1992 in which the regulation with regard to carrier's liability occupied an important position. The author, therefore, selected this issue for demonstration of the legal proinciples about carrier's liability which is provided in the Chinese Maritime Code. The study on the issue is under guidance of related international conventions. On the basis of the above, the differences between the Code and relevant conventions have been pointed out in order to make the people in the field of shipping understood for legal system with regard to carrier's liability in China which is a great potential partner of Korea in shipping and trade.

Recently policy and clouding system to mandate the introduction of BIM in construction industry, various sensors technology, BIM in ICT technology and fusion, such as 3D scanning and printing technology has been further activated. However, the expression level of diversification associated with it, plan within one of the BIM project, design, engineering, it is difficult to have a different application has been consistent for each field, such as construction. Thus fell the efficiency of BIM apply, it is difficult to determine the appropriate level of BIM in the business early stage in order destination of position. In this study, in order to solve this problem, by utilizing SLA used in the IT field, it attempts to explore scheme which can be evaluated targeted level of BIM suitable for business in the planning phase.

This paper aims to explore the strategic roles of information and strategic planning capabilities for firms' performance, and to examine the direct and indirect relationships between information capability, strategic planning capability, logistics performance and competitive advantage. The present research adopts resource based theory (RBT) to explore the relationships between a firm's specific capability and its performance and employs structural equation modelling (SEM) in order to test the validation of the measurement models and examine the relationships between construct variables. The current empirical test was conducted using the data collected from logistics managers of 101 Korean electronics companies. The empirical research presents positive influential relationships between (1) information/planning formality capability and strategic planning capability; (2) strategic planning capability and logistics performance; (3) logistics performance and competitive advantage; and (4) competitive advantage and competitive position in the market.

This study were conducted to reveal the awareness and competitiveness of Korean packaging industry in information technology(IT) and e-commerce. For the survey, 114 sample companies were selected representing all packaging materials, equipment and systems, institutes, consulting and trading companies. The trained interviewers spoke to the respondents who were at the position of packaging research and development and were considered knowledgeable about the level of IT in the company. The collected data were analyze in three major categories: IT fundamentals, usages, and company policy. From the results, packaging suppliers were at the very low level of IT fundamentals and uses compared to those of packaging users. The gap between packaging suppliers and users that access the Internet was seriously wide, and this trend was generally due to different size of company. Packaging suppliers were still at the basic level of information-oriented working environment.
