In this paper, the types of the data exchange between a cell site and a cobile phonefor the call processing on the AMPS(Advanced Mobile Phone Service) are investigated, and the circuit for processing the wideband data stream according to the data types is designed and implemented. The circuit for detecting the Busy / Idle bit which is needed for determining the channel access, the circuit for detecting the word sync and the circuit for transmitting and receiving the wideband data is designed. The 3-out-of-5 majority vote of the 5received data is performed to reduce error and an algorithm requiring a small buffer size for real time processing of voting process is proposed. The method to overcome the computational complexity and the real time constraint of the conventional BCH decoding is proposed.

Currently, Price comparison sites receive inputs of product information and price manually after being joined by releted shopping mall companies, and can't support automatically price fluctuation of products in real time. Therefore, this paper designs and implements web service system based on SOAP for interactive product order and price comparison dynamically using web service technologies in real time. This web service system composes web service client module including functions of product search, sort and order, and server module including functions of remote procedure call for product search and order. This web service system implements interchanging product information based on SOAP messages and can support independence of platform and flexible potability in environment conforming to SOAP, WSDL and UDDI standards.

In this thesis we present the way of visually intuitive interface to the web site users through the comparison of NIN web site with clearly intuitive web site. Improving the web site which has NIN problem to visually intuitive we can achieve web site's visitors who want to buy something got a feeling of graphical excellence and understand web site navigational structure easily through the intuitive navigational design and complete purchasing easily therefore these are to be the basis of the internet business systems goal which is assumed as business success. In a experiment we examine web site's case study and to make an implementation we use flash to solve NIN problem which is improved in a visually intuitive.

The group is one of the hobbies and other life groups, and each person in the group directly attends the meeting and works on the topic of the group. In this paper, we implemented voting, announcements, surveys, and suggestions, which are necessary functions for similar groups including group. We also provide web sites based on Apache web server for convenience of Android smartphone applications, OS except Android, Group management can be managed by using the manager's website which can manage the whole group management. It is designed with Apache web server, web communication language PHP, MySQL database, and Android.

Most of information in Web2.0 is constructed by users and can be classified by tags which are also constructed and added by users. However, as we known, referring by the related works such as automatic tagging techniques and tag cloud's construction techniques, the research to be classified information and resources by tags effectively is to be given users which is still up to the mark. In this paper, we propose and implement a clustering system that does mapping each other according to relationships of the resource's tags collected from Web and then makes the mapping result into clusters to retrieve images. Tn addition, we analyze our system's efficiency by comparing our proposed system's image retrieval result with the image retrieval results searched by Flickr website.

지역 사업에 있어서 주문 배달 시스템은 고객의 편의 제공 및 Franchise의 수익 구조에 큰 영향을 준다. 주문 배달 시스템에 있어서 중요한 점은 다양하게 존재하는 지역 정보들을 효과적으로 이용하는데 있다고 할 것이다. 현재 국내 사이트에서 구축되어 있는 지역 정보 관리 시스템은 분리된 해당 지역 정보만 제공하고 있는 실정이다. 즉, 통합된 체계의 정보 서비스가 되지 않고 있는 실정이다. 전국의 모든 지역 정보 관리를 시행하는 사이트는 전무한 상태이다. 본 논문의 부 프로세스에서는 지역 사업을 하는 데 있어 필요로 하는 다양한 지역 정보를 데이터베이스화하고 그에 따라 여러 가지 형태의 UI(User Interface)를 제공하고, 또한 상점에서 사용하는 사용자 프로그램의 개발과 상점의 특성을 파악하여 그에 맞는 컨텐츠를 제공한다. 본 논문에서는 이러한 부 프로세스의 개발의 기반 구조가 되는 관리자 시스템을 설계 및 구현한다. 즉, 지역 사업을 합에 있어 초기 데이터 구축 및 사업권 영역의 확장 및 관리라는 측면을 고려할 때 각 지역을 관리하게 될 MF(Master Franchise)와 F(Franchise)가 협력하여 현지의 현실감 있는 정보를 즉시적으로 반영하며 구축해 나갈 수 있는 관리자 시스템을 개발한다.

This paper presents ENIG Agent can gather distributed educational newspaper information in the web as well as provide teachers and student those information for the NIE. ENIG Agent gleans newspaper headline of appropriate educational news portal site for real-time provision of those information. The optimized extraction of headline is performed through the pre-process of educational news site, information noise filtering, pattern matching. The educational newspaper headline information that is gotten through previous process will be shown to students by web-browser. To increase the usage of those information, intelligent education methods and visualized classification techniques are used. By experiment, the performance of this ENIG Agent was evaluated.

The purpose of this study is to design the classification system for christian information resources on the internet in Korea. For this purpose, the study is investigated the divisions of Christianity of (1) library classifications: KDC, DDC, LCC, (2) portal sites: Daum, Empas, Naver, (3) Christianity Portal sites GodPeaple, Kidok, Godpia. And it compared the classification systems of KDC, DDC and GodPeaple. This study selected criteria as follows: comprehension, logicality, definiteness, efficiency and current topics. It suggested the classification system(draft) for christian information resources on internet which are composed of 10 classes.

Grid makes a virtual high-performance computing resource by connecting geographically distributed heterogeneous resources. Building access control system is an important factor In the grid environment In this paper, we design and implement a grid access control system based on Globus Toolkit, which is one of the popular grid middleware. Especially, to guarantee the site autonomy for resource provider, we use several environment configuration files. Moreover, we design and implement PGAM to produce more detail and diverse information to ease the development of value added services.

인터넷이 정보사회의 핵심 역할을 담당하면서 각 산업별로 생성되는 방대한 양의 콘텐츠들이 디지털화 되고, 각 인터넷 사이트는 고객의 수요에 따라 다양한 콘텐츠 선점을 통한 사이트의 경쟁력을 높이려 경주하고 있으나 자체 생산과 관리의 한계로 콘텐츠 신디케이션이 등장하였다. 그러나 산업기술 콘텐츠 신디케이터의 입장에서는 다양한 분류와 콘텐츠 제공업체(CP)에 따라서 서로 다른 데이터 표현으로 인하여 정보 수집에 있어 표준화된 프레임웍이 요원하였다. 따라서 이러한 문제점에 기초하여 관련 산업과 국제표준을 고찰해보고 융화시켜 국내 현실에 맞는 범용의 메타정보 프레임웍 구축을 통한 산업기술 콘텐츠 신디케이션 시스템을 설계 및 구현하고자 한다.
