Purpose - The purpose of this paper is to aim to stress the importance of doing business environment in South Korean economy. The theoretical justification is based on neo-institutional theories and new business management including Porter's Model as main justifications of state intervention due to the market failures to promote a competitive environment of doing business. Research design, data and methodology - The methods to be taken is to provide a comparative performance analysis, and offer in terms of doing business and economic freedom sub-index complemented by Korean reforms diagnostics. Results - The main results underlined the key factors explain the success of business environment in South Korea such as: a simplified registration procedures, a target tax incentives, the removal of business barriers, the improvement of legislative and regulatory framework, target reforms, property right and technical norms, good governance and the quality of institution, a role of a well-functioning legal framework, a strong competition framework, and the transparency of regulation, etc. Conclusion - A competitive environment of doing business is based on the target national strategies, appropriate reforms responding to national needs and good governance system.

In the Reporting Cell Location Management (RCLM) system, a subset of cells in the network is designated as the reporting cells. Each mobile terminal performs location update only when it enters one of these reporting cells. When a call arrives, the paging is confined to the reporting cell the user last reported and the neighboring bounded non-reporting cells. Frequent location update may result in degradation of quality of service due to interference. Miss on the location of a mobile terminal will necessitate a search operation on the network when a call comes in. We must decide the number of reporting cells and which cell should be reporting cell to balance the registration (location update) and search (paging) operations to minimize the cost of RCLM system. This paper proposes a simulated annealing (SA) for optimization of RCLM system.

When mobile node moves into the different IP address area, the mobile node can be set the proper environment parameters automatically by DHCP. If we extend the DHCP option field to support the roles of home agent and foreign agent in mobile IP protocol, mobile node can perform the foreign address registration process of mobile IP protocol when DHCP IP environment is achieved automatically, too. DHCP is supplied in the PC with a series of Windows NT. This paper proposes and implements the functional blocks of extended DHCP nodes and this enables the DHCP node have a role of mobile IP agents without another protocol functional blocks.

In this paper, we analyze the DF's problem and propose the solution. We describe the service reservation and Reputation function for searching these services for late registration. Reputation function assume the presence of other agent who can provide ratings for other agents that are reflective of the performance or behavior of the corresponding agents.

Realtime applications like VoIP(Voice over IP) in All-IP networks need smooth handoffs in order to minimize or eliminate packet loss as a Mobile Host(MH) transitions between network links. In this paper, we design a new dynamic buffering(DB) mechanism for IPv6 by which an MH can request that the router on its current subnet buffers packets on its behalf while the MH completes registration procedures with the router of a new subnet. Performance results show that our proposed buffering scheme with a dynamic buffer space allocation is quite appropriate for mobile Internet, or the All-IP environment in terms of the datagram loss rate.

Dynamic (On-line) signature verification system consists of preprocessing, feature extraction, comparison and decision process for internal processing, and registration and verification windows for the user interface. We describe an implementation and design for an advanced dynamic signature verification system. Also, we suggest the method of feature extraction, matching algorithm, efficient user interface and an objective criteria for evaluating the performance.

A standardized communication protocol is required to exchange the data of electric charge and current-using electric power through the two-way communications between the smart meter and electric power supplier. In this paper, a two-way communications technologies is designed for control technologies and de/registration services of electric equipment, and the international communication protocols is applied to the communications technologies.

In this paper, we propose new concepts that the distributed counter value with the distributed EC system identify each user who users the distributed system. The web user should register his/her own user ID in the cyber shopping mall system. Instead of registration, this paper proposes the proprietary mechanism that is distributing counter. The counter assigns the distinguished number to each client. The distributed lock algorithm is used for mutual assignment of the counter to each client. The proposed algorithm is the best solution in the distributed environment system such as cyber shopping mall. If a user should register his/her own ID in every EC system, he/she may not try to use these uncomfortable systems. The mutual counter is used to identify each client. All of these features are designed and implemented on Windows NT web server. Also these features were experiments with 5 clients for 300 times. According to the experiments, clients have their own mutual counter value. The proposed algorithm will be more efficient in internet application environment. Moreover, it will improve the number of internet users.

기존의 제안서 접수 및 평가 방식은 수작업이 대부분을 차지하여 많은 인력과 시간이 소요되며 정확성도 완전히 보장할 수 없는 단점을 가지고 있다. 이러한 비효율적인 방식을 개선하기 위해서 접수 및 평가과정을 웹상에서 자동화하여, 문서 작성자, 접수자, 평가자 및 관리자들이 좀 더 편리하게 관련 작업을 처리할 수 있게 하였다. 자동화를 도입하기 위한 방법으로 HWP 문서의 구조 정보를 표현할 수 있는 마크업(markup) 언어인 HWPML(HWP Markup Language : 이하 HML)을 사용하였으며, HML 문서를 파싱(parsing)하여 필요한 정보만을 추출하여 XML(eXtensible Markup Language) 문서를 생성하였다. 이렇게 생성된 XML 문서는 논리적인 구조 정보를 가지고 있고 플랫폼 및 소프트웨어 중립적이기 때문에 효과적인 검색, 관리 및 공유가 가능한 시스템 환경을 제공한다. 이 기법으로 표준 언어로 부각되고 있는 XML 형태의 문서 관리를 기존의 워드 프로세서 형태의 문서 관리에 확장 적용할 수 있다. 본 논문에서는 이러한 자동화 시스템의 구조와 문서 변환 기법을 제안하였다.
