In this paper, we designed a new type of X-internet framework by using Flash component and server service API and analyzed its performance. Proposed X-internet framework uses Flash MX Professional 2004, Java, and software which opened middleware and database. Since proposed framework use the server service API that we developed in this paper and Flash player, this framework does not need server module. Proposed framework enables to obtain design with dynamic user interface compare to Web application and enables to reduce development time. In analytical results, it has been shown that proposed x-internet framework have efficient characteristics such as network traffic, low development cost and dynamic user interface implementation. Since proposed X-internet framework can operate in environment of current developer friendly, it is useful for development of various new application programs and we confirm it through Flash web mail implementation by using proposed x-internet framework.

In this paper, we developed X-internet framework based on Flash and API for this framework. Proposed X-internet framework based on Flash enables to obtain design with dynamic user interface compare to web application and enables to reduce development time. Since this framework use the API that we developed in this study art flash player, this framework does not need server module. In analytical results, it has been shown that proposed x-internet framework have efficient characteristics such as network traffic, low development cost and dynamic user interface implementation.

The environment of If is, currently, on its developing process to the period of Web Service, Ubiquitous, and Telemetics which not only enable computer and internet to be utilized like the water or the air, but also be a new motivating force for its advance. In the respect of various interactions and User Interface, however, it is requiring more demands from its users, and additional functions which cannot be provided by the Web Browser. It is required a new model for supplementary of the limitation of Web_based according to their customers' requirement, to enrich the good aspects of Client-Server System, and accept such various intricate requirements. It is X-Internet, which has born with these requirements. In this study, therefore, it will be suggested a productive development framework and a method to perform the project on Rich-Thin Client Platform of X-Internet Based.

All industrial Products of today are various demand of customers and are switchovered the manufacturing system of a small quantity batch production. Its life cycle was very shortened. An enterprise is improved to satisfaction with external customers and internal customers of infinity competition time. They can exist on achieving customer satisfaction management. In this paper, a new implementation of service information system (SIS) with real time using RFID and X-Internet in Ubiquitous environments is proposed. The proposed SIS system has Web architecture based on XML and has a new X-Internet environment overcoming limitation of Client/server architecture. The service information system analyze its material data and suppress the same CLAIM creation. The implementation method of real time SIS system using RFID and X-Internet is proposed for contribution of business market reducing F-Cost.

이 논문에서는 디지털 시그널 프로세싱에 적합하지 않은 RISC타입의 DB-X 마이크로콘트롤러를 이용하여 MP3 플레이어를 구현한 방법을 제안한다. DB-X 에는 DSPA 모듈이 있어 FIR, FFT 등 계산이 많이 요구되는 부분을 DSP 수준으로 빨리 연산해 줄 수가 있으며 SSI 모듈이 있어서 44.1khz의 샘플링 주기를 가지는 D/A 코덱과 연결할 수가 있다. 또한 SSI와 음성 데이터가 저장되어 있는 메모리 사이를 CPU 부담없이 데이터를 전송하기 위한 DMA 모듈이 있어 MP3 데이터를 프레임 단위로 디코딩할 때 더블 버퍼링 기법을 쉽게 사용할 수가 있다.

최근 응용 프로그램은 대다수가 웹으로 이루어져 있다. 그것은 빠르게 변화하는 비즈니스 시장에서 살아남기 위해 기업들이 배포 및 유지보수가 쉬운 웹 응용프로그램을 선호했기 때문이다. 하지만 이제는 다양한 고객의 요구조건을 웹 응용 프로그램이 충족시키기에는 한계가 있다. 이런 문제를 해결하고자 많은 기업은 앞 다투어서 새로운 인터넷 구조인X-Internet기반의 응용프로그램을 출시하고 있으면 기업들도 도입을 서두르고 있다. 본 논문은 X-Internet 기반의 응용프로그램과 웹 응용프로그램의 성능을 비교 분석함으로써 X-Internet 기술의 가능성을 알아보고자 한다.

The aim of this research was performance of Web-based real time DGPS using MS visual basic 6.0 Active X control. This system supported the navigation of rover by transmitting the DGPS correction information of base station via internet and monitored the moving of rover by displaying the corrected results received from rover as well as permitting Web users monitoring for rover. The Web-based DGPS server and the client system using MS visual basic 6.0 Active X control for DGPS displayed on Web-browser with the pre analysis was constructed and the system loading test via Web-browser was performed after debugging this system through the static GPS test and publishing it on Web. Also, the wireless internet DGPS test on Web by changing the distance between a base station and a rover was carried out. As the result of the test, the real time DGPS could be performed by transmitting the correction message which calculated from the server system to the client system continually. The rover could be managed by displaying the location information which received from the client system. Other users also could monitor the rover by connecting with this system via internet in real time.

X-Internet 과 X-Forms 기반의 UI 소프트웨어 시스템은 개발이 완료되어 운영되는 과정에도 요구 사항의 변경, 성능 향상, 개발 과정 중의 오류 등의 다양한 이유로 변경될 수 있다. 기능 변경은 테스트 케이스 작성 시간과 비용의 증가로 이어진다. 본 논문은 소요되는 시간과 노력을 최소화하기 위한 테스트 케이스 작성 기법을 제안한다. 이를 위해 테스트할 기능을 분석하고 기존의 테스트 케이스에 새로운 기능을 접목하여 작성할 수 있는 테스트 케이스 재사용 알고리즘을 제안한다. 또한 오류가 전체 영역에 분포하지 않고 특정 영역에 분포하는 속성을 이용하여 모든 테스트 케이스를 생성, 실행하는 것이 아니라 오류를 잘 찾을 수 있는 테스트 케이스를 선정하여 테스트하는 기법의 효율성을 증명한다.

I propose adding users’Media Access Control (MAC) addresses to standard X.509 certificates to provide more secure authentication. The MAC address can be added by the issuing Certification Authority (CA) to the "extensions" section of the X.509 certificate. I demonstrate that when two users with MAC address information on their digital certificates communicate, the MAC address on the first user’s certificate can be easily verified by the second user. In this way, security can be improved without markedly degrading system performance and the level of initial trust between participants in virtual communities will be improved.
