A Study of Product Trade Service using Mobile Agent
Journal of the Korea Society of Computer and Information, volume 6, issue 3, 2001, Pages 1~10
Recently, way of Electronic Commerce is changing with increment of Internet users. In the previous way of commerce, users used to search for information by themselves. However, for user's convience, it can be done for users from one site. Mobile in order to provide users with such service. By the mobile agent-based Electronic Commerce system, users can get information from one site, and service companies can provide various and useful information to users. This is very important for construction of reliable Electronic Commerce environment, However, in generally used mobile agent-based platforms, the user should know URL information. and it is based on search engines. And as user's requirement levels become higher, they want to be provided with integrated and summarized service. In this paper, we implement product-trading system by applying mobile agent concept in order to satisfy user's requirement of getting required information from one site with minimal mouse click. For implementing the product trading system, E-speak, which is a platform for E-Service, is used And contents are saved as XML documents and data are shared based on these documents.

A Study on the referential Component Architecture and UML Specification
Journal of the Korea Society of Computer and Information, volume 6, issue 3, 2001, Pages 23~28
There has been several meaning full efforts to save costs on system development and expand the life-time of a system in changeful IT circumstance. It was a module-based architecture that empower productivity at structured programming era. But it couldn't grow nor evolve, but could raise only calling frequency of module. But OOP or OO-method overcome limit of structured programing by class inheritance and/or overloading and/or over-riding. A component centric architecture, what is mixture of distributed systems, like CORBA or DCOM with OOP, can support not only high reusability or expansion of life-time but also Plug-&-Play between them. To assemble these component to build a new system in easy way, the well-formed specification of a component is highly required. At this study, the enhanced referential component architecture and its UML specification will be suggested.

The Method of Handoff Using CLP on the WATM Network
Journal of the Korea Society of Computer and Information, volume 6, issue 3, 2001, Pages 44~49
In general. requirements for QoS are different according to the type of services in wireline and wireless ATM, and real-time video service is more sensitive to cell transmission delay than to cell loss. Existing handoff schemes emphasizing prevention of cell loss had limitations in cell transmission delay to satisfy QoS. In this paper, a novel scheme to transmit ATM cells with low CLP (when CLP = 0) prior to others and discarding cells with high CLP (when CLP = 1) in ATM cell header among cells to be forwarded during handoffs in real-time VBR service is proposed. The proposed scheme is proven to be suitable for the satisfaction of QoS and appropriate for fast handoffs by giving high CLP value to less meaningful MPEG frames through simulations.
