A seismic isolation system is one of the most effective control devices used for mitigating the structural responses due to earthquake loads. This system is generally used as a type of base isolation system for low- and mid-rise building structures. If the base isolation technique is applied to high-rise buildings, a lot of problems may be induced such as the movement of isolation bearings during severe wind loads, the stability problem of bearings under large compression forces. Therefore, a mid-story isolation system was proposed for seismic protection of high-rise buildings. Residence-commerce complex buildings in Korea have vertical irregularity because shear wall type and frame type structures are vertically connected. This problem can be also solved by the mid-story isolation system. An effective analytical method using super elements and substructures was proposed in this study. This method was used to investigate control performance of mid-story isolation system for residence-commerce complex buildings subjected to seismic loads. Based on numerical analyses, it was shown that the mid-story isolation system can effectively reduce seismic responses of residence-commerce complex tall buildings.

Concerning the regulation of Internet service and the control of electronic commerce in China, It has not specific regulation and various rules or measures to enforce it yet. The common regulatory measures are that online business in some special areas must acquire a license or approval from relative agencies in advance. But whether licensing is an effect regulatory measure still takes time to verify. Accordingly these measures must be unified or coordinated to be enforced effectively. In order to encourage the development of E-Commerce, China will need to focus on developing rules that take advantage of the internet to encourage the economy, and establishing new legal rules or amending the traditional law to create a safe and secure legal environment for online transactions.

It is required the electronic commerce system for satisfying the various information needs of user groups on the high speed communication networking. However, its information amounts will be explosive, and make it difficult for users to locate information they are interested in. Therefore we have developed the architecture of information searching platform for electronic commerce which searches and gathers information about electronic commerce site on internet and builds the keywords index database for serving the client's requests in order to provide non-professionals and small companies etc., with access easily to retrieval information.

Because XML is a W3C standard and has characteristics like platform-independent, it has a critical role in e-commerce. Business rules and procedures should be standardized for efficient B2B integration. But a lot of companies has its own XML documents instead of standard documents. Therefore many organizations try to make standards for e-commerce based on framework. In this paper, n messaging system is designed and implemented. Client request service in a XML and server return response in XML in this system. So we can more easily and efficiently build e-Procurement system based on this XML messaging system.

With the advances of wireless technologies and mobile computing, m-commerce is being realized for several mobile devices such as PDAs and mobile phones. Currently, service contents in m-commerce are usually newly written to meet specific characteristics of the target mobile devices, thus requiring formidable efforts. Therefore, we should exploit the Internet product information currently being provided for e-commerce. However, bringing the Internet product to mobile devices is far from straightforward due to the many limitations of mobile devices such as little memory, small displays, low processing speeds, and so forth. In this paper, we first suggest a new model to effectively adapt the Internet product information for mobile phones. We then suggest a mobile system to implement the model. We then design and implement the system. Finally, we give experiments on the system.

This research has designed and implemented the standard conformance test system for e-Business solutions that supports the ebXML, which is currently being focused on as the leading electronic commerce framework. The adoption of standards such as ebXML is probably the best way to achieve interoperability among electronic commerce systems, and more and more e-Business solutions around the world are supporting ebXML. This research primarily discusses the concept and needs for the standard conformance tests on e-Business solutions. The standard conformance test system is developed based on the detailed specifications of the ebXML framework. This system was used to test commercial e-Business solutions supporting ebXML. The system implemented in this research will provide a significant basis for the standard conformance certification of e-Business solutions, and could also provide clear decision criteria for e-Business solutions currently in market, thus activate the overall e-Business market.

Legal rules applying to the commerce and international commerce in particular contracts, proper law, jurisdiction and so on, have improved with time and experience. Engaging in e-commerce on the World Wide Web may expose the company to the risk of being sued in any foreign country where Internet user can establish a legal claim. The modem law of contracts is highly sophisticated and difficult to understand. With contracts created in cyberspace, the basic rules are no difference that we can find. However, there are situations in e-commerce that are altogether new and to which the existing rules cannot apply. Here uncertainty and business risk is too high for trading partners to deal with certainty. Therefore existing law must change to e-commerce law so that it provides certainty and enforceability over e-commerce. UNCITRAL Working Group on Electronic Commerce prepared the Preliminary Draft Convention on [International] Contracts Concluded or Evidenced by Data Message from the thirty-ninth session in 2002 which applies to international contracts concluded or evidenced by means of data messages. An electronic contract is concluded when the acceptance of an offer becomes effective, and an offer becomes effective when it is received by the offeree, and an acceptance of an offer becomes effective when the indication of assent is received by the offeror according to this Convention. Electronic contract may be concluded by the interaction of an automated computer system and natural person or by the interaction of automated computer systems, and a contract formed by a natural person that accesses an automated computer system of another person has no legal effect in case the neutral person made a material error in a data message.

In this paper, we research a virtual card generation system to secure e-commerce. Network security has increased the need to meet rapidly growing trend. And the amount and quality of e-commerce expansion due to the need for secure commerce transactions has increased even more. Instead of exposing the actual credit card number, we expose a virtual card number on the network. It can prevent the risk of hacking. We proved that through various experiments.

Recently, as the number of used trading sites supporting used trading increases, users want to search for a variety of information in real time. This new change has enabled a new type of C2C (Commerce to Commerce) transaction in the e-commerce base. However, since each used trading site has its own characteristics, it is difficult to standardize the whole. Therefore, in this paper, we studied a system that provides the transaction data used by the user in real time and provides the desired information quickly. In this paper, we researched the crawler system necessary for the development of the integrated trading system for used goods through Internet e-commerce, and made it possible to provide information in the web environment desired by the user through the defined morpheme analyzer. Therefore, in this study, we designed a system that provides information desired by users without accessing various used goods sites.

The importance of electronic commerce system has been growing rapidly due to development of information technology and acceleration of enterprise e-business. Electronic commerce system must provide convenient interface, easy and fast searching function, and product information satisfied customer's. A study about the system that used a reasoning technique and an Agent technology for this is required. In this paper, we designs electronic commerce system with customer preference and sales agent which is composed of case-based reasoning and rule-based reasoning for high customer satisfaction. Also, we were shown on an appropriateness of a proposal system by an experiment.
