The area of business applications in the internet are extended enormously in result of fast development of computing and communication technologies, increase of internet use, and use of intranet/extranet in enterprise information system. In recent days network computing technologies have been developed rapidly and the extended use of Internet applications for enterprises such as intranet/extarnet in and between enterprises has been increased enormously. Therefore the business in the future will be executed by Electronic Commerce based on Business to Business(B2B). <중 략) This paper introduce the design and implementation of the data sharing support system that can be accessed data transparently by the users of participated enterprises in the integrated data environment supporting B2B Electronic Commerce. The system uses Java/CORBA technology in Web environment, relational and object-oriented database system, Object Query Language (OQL) to process the queries of the file information.

This paper gives a comprehensive overview of the SSO solution design on the intranet. SSO described in this paper is based on LDAP, PKI and CA. We designed the data structure to hold many various application services by changing the attribute and DN of LDAP DB. We built LDAP DB using the employee records stored in our organization database. LDAP DB is routinely updated from the database. CA Server that depends on PKI is used to issue the certificates. SHTTP based on SSL is used to protect the data between certificate server and the intranet users.

With the growing usage of the networks, the users in the Internet uses some kinds of web server. They confused that each web server uses the different user ID and passwords. To solve these problems, SSO (Single Sign-On) solution is introduced. We presents the modeling methods which are efficiently constructed the network management models. We constructed the intrusion detection systems and firewalls using the SSO. This architecture is efficient to manage the network usage and control. SSO solution designed on the small scale Intranet. CA server in the 550 that depends on PKI (Public Key Infrastructure) is used to issue the certificates. SHTTP based on SSL (Secure Socket Layer) is used to protect the data between certificate server and the intranet users.

The specific objectives of the study were as follows: 1) To investigate the composition system (design, usability and interactivity) of web sites of textile exchange of B to B 2) To examine and valuate contents and marketing (announcement, satisfaction and variety of contents) of web sites of textile exchange of B to B. The data were collected from search engine, portal sites of evaluation, direct contact, interview over the phone with web master of concerned web sites and the result of analytical valuation of web sites. The results of this study were as fellows: 1) The Dongsung trading intended to mainly use their homepage as a inside communication place by intranet network. The Daechang trading was mainly using their homepage as a tool of expansion of their outside export market. The etextiler was selling their web solutions through homepage. The texcom was offering the web place and useful informations to trading companies in Asia. 2) The texcom consisted text with little image to speed up for loading and navigation for usability of users. The Dongsung trading made intranet network for communication and exchange of informations of company inside. The etextiler offered a booking menu to inquiry in homepage. The Daechang trading tried to give good impression from the introduction page at homepage.

This paper presents research in intelligent massenger technique for Cyber University to support accessing university database. Proposed techniques enables better communication between students and professons by using intelligent messenger. Intranet based massenger support simple message transfer and multimedia chatting service within homogeneous network or members in same group. Using niversity database it provide personalize information for each different user demand needs and through managing technique user could effectively organize members of group. To embody intelligent massenger, JMF(Java Media Frame Work), RMI(Remote Method Invocation), XML techniques were proposed and in result constructing effective community.

Recently, design patterns have been known to be highly effective and practical. Design pattern is a collection of collaborating classes that captures the application independent behavior of system in a particular domain. By using design pattern, the development time and software quality can be greatly increased. However, systematic development process and detailed instructions of building design patterns have not been studied enough. In this paper. we propose practical intranet structure modeling technique that are based on design pattern. The proposed process consists of the four typical software development phases; analysis, navigation, interface, behavior domain design, and each phase is defined as a logical sequence of development tasks. Since the proposed process is based on design pattern foundation, and can be efficiently produced by applying this process.

This research is on the study of integrating internet and intranet that was built for their own enterprise into one network system that promises a more economic and secure use. Compared to this system, the traditional network conversion device not only has its mechanical limits, but also requires a separate network set up. This raises both interoperability and security problems and results in a higher cost. Therefore, I propose dual defence system based on the inverse multiplexing of ATM Forum and IPSec to improve network ability and deliver enhanced system reliability while reducing cost. Furthermore, I also addressed some of the weaknesses of the Scanning Attacking Method, SNMP and Spooler Port and proposed counter measures that will deal with these weakness at the dual defence system.

We developed a HPMA Information System to establish the voluntary safety management for the Paint Industry. HPMA System means that manager, supervisor and worker on the process-line find out the hazardous and/or unsafe potentials, make improvement of the field safety by the cooperation with top manager, safety staff and eventually put in the practice. HPMA Information System consists of functions to suggest and evaluate the safety concerns hierarchically from top manager to workers on internet or intranet. We establish the safety management and sharing of the safety information and are able to find the unsafe potentials by the HPMA Information System. Also We are able to mine new safety information and establish accident prevention model by the Safety DATABASE.

In order to provide real-time data from sensors and instruments at manufacturing processes on web, we proposed a communication service model based on XML(eXtensible Markup Language). HTML(Hyper Text Markup Language) is inadequate for describing real-time data from manufacturing plants while it is suitable for display of non-real-time multimedia data on web. For applying XML-based web service of process data in Intranet environment, real-time performance of communication services was evaluated to provide the system design criteria. XML schema for the data presentation was proposed and its communication performance was evaluated by simulation in terms of transmission delay due to increased message length and processing delay for transformation of raw data into defined format. For transformation of raw data into XML format, we proposed two structures: one is the scheme where transformation is done at an SCC(Supervisory Control Computer) after receiving real-time data from instruments. the other is the scheme where transformation is carried out at instruments before the data are transmitted to the SCC. Performances of two structures were evaluated on a testbed under various conditions such as six packet sizes and offered loads of 20%, 50% and 80%, respectively. Test results show that proposed schemes are applicable to the systems in Ethernet 100BaseT network if total message traffic is less than 7 Mbps.
