Development of Web service application requires the interoperability between various heterogeneous systems, extensibility to allow modification of business environment not of user interface, maintainability, flexibility and reusability As the properties of CBD (Component Based Development) have gradually become clear, attention has started to turn the smooth technology and methodology to solve the existing problems and issues the dynamic responds for the distributed web environments. In this paper, we identify some of the major architectural affecting CBD and describe the Design and Implementation of Security Framework for Application Server with Components. We identify the candidate components, model it using UML and layer it on the architecture. The frameworks will Provide the various security functions, such as incorporating with legacy security systems, supporting of J2EE, JAAS and Kerberos and assisting in increasing the tailorability of component.

Recently, the world's Information Society, already central to humankind, is rapidly changing towards a fully ubiquitous computing society through the development of USN technology. USN application web services provide convenience through environment recognition as well as automatic recognition of specific situations all through the use of USN technology. It has been proven that it can also enable the safety of human life by providing an optimal service through real-time management. Therefore, USN application web services using such technology can be applied to various aspects of life. In this paper, we have implemented a scenario of with a specific user requirement regarding collected meta-data and sensing data based USN technology. We have implemented a visualization of the solutions suitable for each scenario.

This paper describes the developmnet of a web-based boiler controller which can be in parallel operated with an existing boiler controller. The web-based boiler controller mainly consists of RTL8019AS NIC and TS80C32 microcontroller. In order to communicate over the Internet, we need to develop network driver, IP, TCP, UDP, ICMP, and HTTP. For a specific application like web-boiler controller, we have proposed a common global data buffer algorithm to minimize the RAM memory usage. Finally, the correctness and performance of the protocols are tested and verified using CommView and Dummynet. The development is satisfactorily operated only for few hundreds of bytes of RAM usage without sacrificing interoperability between hosts.

웹을 이용한 클라이언트-서버 데이타베이스 시스템은 웹의 서비스 능력과 데이타베이스 시스템의 데이타 관리 기능을 상호 보완적으로 통합함으로써 인터넷과 같은 대규모 환경에서 데이타베이스 업무 환경을 구축하는 데 매우 적합한 것으로 알려져 있다. 데이타베이스 통로는 이러한 통합의 가장 핵심적 구성 요소이다. 본 논문에서는 먼저 클라이언트-서버 데이타베이스 응용을 위한 데이타베이스 통로의 고려사항으로서, 고성능 실행구조, 응용 프로그램 개발 환경, 그리고 상태 및 트랜잭션 관리에 대해 기술하고, 이어서 UniSQL/X용 데이타베이스 통로인 UniWeb 2.0의 설계와 구현에 대하여 소개한다. UniWeb 2.0은 CGI 응용 서버 방식을 채택하여 다양한 플랫폼을 지원하고, 고성능 그리고 확장성을 제공한다. 또한 프로그래머가 HTML 문서에 SQL/X문장이 포함된 Tcl 스크립트를 끼워 넣을 수 있도록 하여 응용 프로그램 개발 생산성을 향상시키고 있다. UniWeb 2.0은 여러 웹 페이지에 걸친 상태 와 트랜잭션을 지원하고 있다.

Web-based learning is currently an active area of research and a considerable number of studies have been conducted on its application in the learning environment. However, in spite of many advances in the research and development of the educational contents, questions about how the environment affects learning remains largely unanswered. In this article, we propose a Web-based learning environment to improve the educational effect. The goal of this article is not to provide a complete system to support Web-based learning but rather to describe some meaningful strategies and fundamental design concepts that utilize information technologies to support teaching and learning.

XML Web Service based on internet can cause problems on transmission speed and data error. Also system analysis results simulated by several different research groups can hardly have reliability because of error data that come from improperly managed files. In order to solve this problems, algorithm sever using XML Web Service is shared on the internet so widely that various application programs based on basic analysis module with a united IO can be developed. And also XML Dataset DB is interacted with XML Web Service, which prevents propagation of error data. It causes to improve reliabilityon the load flow analysis result and solve the problems on data error or transmission speed that can possibly come from internet.

As the interest in internet business increases, effective web site evaluation is in order. While web site evaluation is supposed to be based on feasible applicability and trust-worthy criteria. many researches on web site evaluation fails to rover the various business models and consider corporate-activity-related features. Besides, dealing with the limited aspects such as design and cognitive science is something to be desired on the previous researches. Therefore, This paper presents internet web site evaluation framework not only based on existing researches and analysis but also reflecting corporate strategies. The framework includes web sites contents, design, operation and management-related factors, and it is applied to companies to validate its applicability.

사물인터넷(Internet of Things)의 도래와 함께, 무선공유기(wireless access point)들의 보안이 심각한 문제로 대두되고 있다. 연구진은 대부분의 무선공유기들이 제공하는 웹 기반 관리 인터페이스들에 웹 어플리케이션 취약점(web application vulnerability)들이 존재할 수 있다는 점을 착안, 국내 주요 무선공유기들에 대한 웹 어플리케이션 취약점 점검을 수행하였으며, 악용이 가능한 여러 취약점들이 존재함을 확인하였다. 본 논문에서는 연구진이 무선공유기 대상 웹 어플리케이션 취약점 점검에 보조적으로 사용하기 위하여 개발한 3종의 모바일 앱(mobile app)들을 설명한다.

Finding publications that propose alternative methods to animal experiments is an important but time-consuming task since researchers need to perform various queries to literature databases and screen many articles to assess two important aspects: the relevance of the article to the research question, and whether the article's proposed approach qualifies to being an alternative method. We are currently developing a Web application to support finding alternative methods to animal experiments. The current (under development) version of the application utilizes external tools and resources for document processing, and relies on the PubAnnotation ecosystem for annotation querying, annotation storage, dictionary-based tagging of cell lines, and annotation visualization. Currently, our two PubAnnotation repositories for discourse elements contain annotations for more than 110k PubMed documents. Further, we created an annotator for cell lines that contain more than 196k terms from Cellosaurus. Finally, we are experimenting with TextAE for annotation visualization and for user feedback.

The purpose of this study is to analyze the needs of mathematics learning program using web or application for the development of adaptive mathematics learning program. For this study, a questionnaire survey was conducted for middle school students. The results of the 290 responses were analyzed to identify students' needs for adaptive mathematics learning. As a result, learners wanted functions to design their own learning and to support self-directed learning. The results of this study are expected to be used as basic data for the development of a adaptive mathematics learning program reflecting students' needs.
