The aim of this study is to thoroughly review prior literature related to electronic bill of lading and investigate the current state of electronification of operational processes of both major international and domestic shipping lines. In addition, this study examines the meaning of Electronic Bill of Lading; the perception on Electronic Bill of Lading; and the impediment to Electronic Bill of Lading in the perspective of shipping lines. As a result, following obstacles deter further development of e-B/L: negative attitude on the utilization of e-B/L; the matter of trust on the utilization of e-B/L; and technical issues in relation to the use of e-B/L.

This study criticizes the wave of liberalization, privatization, thoughtless and uncontrolled over-competition in the electronic communication networks area. This criticism is based on the 'transport economics' on one side, the 'network neutrality debate' on the other side. Through these standpoints, this study insists that it needs to deal with a social agenda related to the problems such as unplanned and unbalanced development of electronic communication networks, double/tripple-investment in the communication industry, conflicts among network companies and the decline of public values. Also does this study stress on the new ideas in the electronic communication network policy and planning to manage these problems. Electronic communication networks are converging and their borders are blurred. As a result of these flows, the field of information technology, media and contents is faced with radical changes. These changes could be so critical and complicated that nobody can diagnose their multi-level implications. However, the one thing sure is that we should start from the communication networks to think and control a communication system. Therefore, we should discuss and plan the now-and-future of communication infrastructure and its management. we need not only a market mentality but also a socio-cultural mentality. In this respect, this study does insist that it requires the vision of digital democracy and democratic communication ecology to put the steps toward social communication system.

LCD (Liquid Crystal Display) is widely used electronic product. It needs too many processes such as PECVD (Plasma Enhanced Vapor Deposition), Sputtering, Photo-lithography, Dry etch. Each process is important but inspection process is more important because most companies emphasis on the six sigma. Recently, LCD inspection system is composed with inlet, inspector, outlet air pads. LCD is inspected on air pad which is shooting air from air hole. This paper studies on pad design of air bearing for LCD inspection to minimize LCD fluctuation. This design is able to reduce fluctuation and then satisfies CCD inspectional range. Also inspection pad needs to adequate stable area.

This paper's objective is to provide insights about the problems and expansion strategies of electronic trade. Korean small and medium-sized firms have adopted the Internet since the end of 1990s in order to reshape their competitiveness, and it is now being utilized as a major export marketing instrument to develop new customers, save export transaction costs ad facilitate new work processes. However, at present, the use of the internet in the field of trading is limited to the collection of market information, owing to legal, technical and institutional restraints between countries. In addition to that, because firms have the difficulties in making the trade contract through the e-trade system, the negative recognition on its' utility has been spreaded gradually between companies. This is one of the barriers to block the expansion of e-Trade between Korean firms. Therefore, this paper points out the problems of e-trade in the environmental, institutional and strategic view and provides many considerations for establishing the expansion strategy of e-trade by the Korean government and trade supporting institutions.

Product catalog information is the most important factor to make customers purchase the product for various B2B or B2C businesses provided on the Internet. As catalog information differs from company by company, it cannot provide common criteria standard to customers to make decisions. Therefore, it is necessary to develop a platform independent system, which integrates incompatible data from each company' catalogs and manages its database. This paper describes the integrated E-catalog system made up DB module, catalog management module, and interface module. This system allows customers to view standardized product catalog information from different companies with real -time updates, and also provides extensibility, flexibility, and interoperability for the effective E-Business management.

To solve the problems of energy and environment conservation issued recently, mainly in mechanical engineering point of view, R&D's on the thermal, fluid and environmental engineering technology have been carried out by two R&D departments in the Korea Institute of Machinery & Materials (KIMM). Now there are 65 researchers in the two. The representative projects in the field of thermal and fluid engineering are development of an inactive gas generator and development of a cryogenic cooler for electronic sensors. Pyrolysis and melting of wastes, gas treatment using nonthermal plasma, and desalination are important technology to be developed in environmental R&D areas. To reduce the emission from the existing diesel engines for buses, an LPG direct injection type of bus engine is being developed supported by LPG supply companies. These several R&D projects which have been carried out in KIMM are introduced briefly.

Today, most companies are building up and using online communities on their websites. But there are few studies on forming and operating online communities. This study shows the influence of social presence on these factors like usefulness, ease of use, playfulness, satisfaction community trust, and its ultimate contribution to community flow. An Empirical results suggest as follows. (1) social presence has stronger effect on usefulness, ease of use, playfulness, (2) usefulness and playfulness has a positive influence on satisfaction, (3) ease of use doesn't have a significant impact on flow, (4) satisfaction is positively influences on community trust and flow, (5) community trust influences on flow. It is necessary to succeed with next studies following this one about online community in spite of its limitation. Finally, we present contribution and propose future research directions.

Electronic commerce (e-commerce) has seen as the potential to improve profitability and productivity in many areas as well as gaining notable attention in many countries. Despite, there has been some uncertainty about the e-commerce impacts for developing countries. The sufficient basic infrastructural deficiency, socio-political, economic and the lack of government public ICT policies have formed the significant barriers to the adoption and e-commerce growth in developing countries. Even though there are many researchers have found the common barriers to e-commerce in the developing nations, all business models targeting those countries are not equally successful. Small companies' persistence failed to challenge the e-commerce barriers in Cambodia because the firms didn't know the correct business model to succeed in this country online market. Therefore, this study will discuss the existing barriers which lead to limit e-commerce growth in Cambodia and the suggested solutions with the suitable business model for the e-commerce business in the country too.

Recently, a lot of domestic construction companies have implemented Knowledge Management System. However, most of the knowledge in the construction fields still cannot written down on papers, and it is just locked in people's heads. The purpose of this study was to analyze the current situation of knowledge sharing in the construction fields. For this research, questionnaires were distributed and the results of this study was as follows; the essential factor of successful knowledge sharing is not introducing a high quality of electronic system but developing culture of knowledge sharing. When positive culture of knowledge sharing is combined with technical infrastructure, knowledge sharing will be actively promoted.
