At present, electronic commerce is relatively small, but it may crease on a large scale in the near future, the increasing use of electronic commerce over Internet raises question about issues in cyberspace, For that reason this study I identified several problems which currently represent an obstacle for the wider use of electronic commerce mechanisms over Internet and contemplated the international movements and Korea's response of electronic commerce on major issues, Eventually, in order to cope with Internet Round and ensure the stable growth of Electronic Commerce in Korea, the government needs to construct a predictable standards and Commercial environment, suitable to the both the situations of Electronic Commerce, for business conduct on the Internet.

We have performed Liquid Chromatography-Solid Phase Extraction-NMR (LC-SPE-NMR) analysis for liquid crystalline mixture and elucidated the structures of selected components by NMR spectra. Combining the results of one-dimensional 1H experiments as well as homonuclear and heteronuclear two-dimensional experiments, we could analyze the molecular structure of the liquid crystal singles whose structure had not been interpretable by mass spectrometry alone.

This paper intends to describe the concepts and historical development of information resources in the digital library, to analyze the different types and characteristics of electronic information resources, and to comment the cases of electronic information resources-especially electronic books, electronic journals, and electronic newspapers. Over the centuries, since the introduction of the printing press, conventional books have played a fundamental role in a wide range of information dissemination and knowledge transfer activities. But, I have mentioned some of limitations of conventional books and electronic information resources in this article. In order to overcome some of them, I think that we should introduce the idea of electronic information resources as a means of storing, sharing and communicating large volumes of dynamic multimedia information.

Recently mechanical watt-hour meters are being replaced by electronic watt-hour meters. The replacement period of mechanical watt-hour meters is 7 years. This period is based on long term historical data. The replacement period of electronic watt-meters is also 7 years. This period is determined using the replacement period of mechanical watt-hour meters. However lifetime of mechanical watt-hour meters is different from the lifetime of electronic meters. In order to determine desirable replacement period of electronic watt-hour meters, accelerated life tests of major components in electronic watt-hour meters were performed. The test results showed that LCD was the component which had the shortest lifetime. In this paper, lifetime of electronic watt-hour meters manufactured by 3 company was estimated and life test standard for LCD was developed.

This study is to implement electronic catalog that is necessary for Web-based electronic commerce and one of many application areas in digital libraries technologies. According to development to digitize various type of paper documents that are used at electronic commerce. We demonstrated limitations of HTML and XML that are being used for current electronic catalog, and introduced newly developed cXML. We have also implemented new electronic catalog using cXML in order to develop and research standardized and secured electronic commerce.

This paper intends to describe the concepts and historical development of electronic library, to examine some of information technologies such as CD-ROM, electronic books, multimedia and networks, and to analyze cases of electronic library. Electronic library is able to offer many services in digital form, ranging from bibliographic databases on CD-ROM running on standalone computers, to fully networked abstracts and texts, available inside and outside the library. For users, the electronic library is a means of improving the speed of access to library materials, of providing a simple means of the selecting materials amid the glut of information available, and of eliminating the need to visit a library for many information inquires. In summary, electronic library has the potential to give scholars better service than conventional libraries, at a lower cost. However, remember that, today, almost all these benefits are still potential.

Trajectory modeling is foundational for 4D-Route modeling, conflict detection and air traffic flow management. This paper proposes a novel algorithm based Vincenty's fomulas for trajectory calculation, combined with the Dijkstra algorithm and Vincenty's formulas. Using flight plan simulations our experimental results show that our method of En-route trajectory calculation exhibits much improved performance in accuracy.

The development of information & telecommunication technology and internet-based electronic commerce helps to create a new economic environment. Such an economic environment requires the companies to change themselves, while providing unlimited potential and opportunities to them. Thus, in order to help the companies engaged in a fair and free competition in the electronic market, a fair competition policy needs to be designed and operated. The electronic commerce has not only promote the competition but also impede it. The electronic commerces tend to violate the fair trade than the conventional commerces in terms of differentiation, monopoly, conference, limited competition and intellectual property rights, schumpeterian competition, Alliance competition. With such basic concepts in mind, this study was aimed at reviewing the economic effects of the electronic commerce in the market and addressing the problems involving the application of the fair trade code to the electronic commerce, and thereby, suggesting the insights into our fair competition policy and reform measures.

There is a big change in Electronic Commerce. With little or no profit projected for the foreseeable future with the dotcom companies, Internet venture capitalists are looking for new business models. They are now turning to B to B Electronic Commerce. It is expected that B to B Electronic Commerce will be more active than B to C in the very near future. In the future B to B Electronic Commerce will move to include collaborative Electronic Commerce which includes product development, engineering, material procurement, and management. Even though the solution to this multidimensioal and complicated process may take some time, a total solution to this will dramatically change the landscape of Electronic Commerce. Thus the various corporations must work together to find the total solution that will build this infrastructure.

China has recently (28 August 2004) adopted a new act legalizing the electronic signature. This new act provides electronic signatures with the same legal status as handwritten signatures, and states that on-line certification providers will have to be created in order to ensure the security of on-line operations made using said signatures. This new act is intended to increase Chinese electronic business, and thus to raise the revenue China can expect from said business. And the law grants electronic signatures the same legal effect as handwritten signatures and seals in business transactions, and sets up the market access system for online certification providers to ensure the security of e-commerce. As Internet trade requires a reliable third party to identify the signers, the credibility of online certifying organizations is significant for the transaction security. So, considering the weakness of China's social credibility system, the law regulates that the online signatures certification providers should be approved and administered by governments.
