Recently, many kinds of XML based application services are widely used in internet. And the markets for mathml editor are needed for the technology combined with other text editor. We are developing a system for MathML based browser and editor for the service of internet application. MathML based browser is applicable for e-book service and many kinds of document system. This system is composed of document editing module and displaying processing module. This system isfor the processing of MathML tag by unexperienced users with MathML syntax. Users can edit the math tag's documentwith ease and efficiently. Based on XML, many parser's functions are optimized for the speed of document processing. This system ran afford to the development of internet world.

웹서비스에 대한 높은 관심과 함께 그 실현이 점차 가시화되고 XML로 이루어진 지원 기술들의 전폭적인 지지로 잠재력은 더욱 확대되고 있다. 웹서비스는 기존 웹 기반의 디스플레이에 그쳤던 단순정보 교환을 애플리케이션 차원에서 데이터를 통신할 수 있어 개발 가능성이 무한한 프레임워크로 각광받고 있다. 그러나 현재 자원 관리에서의 효율성 문제가 드러나게 되었고 인증분야와의 접목에서도 한계를 드러내고 있다. XACML은 리소스에 대한 미세한 접근제어를 할 수 있는 XML기반의 언어이다. 접근하려는 리소스는 XML을 사용하여 표현되는 어떠한 객체도 될 수 있으며 XPath나 LDAP과 같은 프로토콜과 함께 바인딩하여 사용될 수도 있다. 보다 효율적인 접근 제어를 위하여 XACML 적용 모델을 연구하였다.

기업간 전자상거래가 협업 모델을 통해 확산되는 가운데, 국제 표준으로 제정된 ebXML과 민간 컨소시엄 주도로 진행되고 있는 웹서비스는 협업 B2B 부문의 대안으로 강력히 부상하고 있다. 일반 기업 및 사용자들은 시스템을 도입함에 있어 비용 대비 효과라는 측면과 기간 시스템과의 연동이라는 아키텍쳐 측면에서의 고려가 다 필요한 만큼 두개의 B2B 프레임웍을 다각도로 비교/분석해 보는 것은 의미가 있는 일이라 하겠다. 본고에서는 업무 프로세스의 정의 방법, 표준 데이터 구성방안, 서비스 등의 측면에서 양 프레임웍을 비교해 보고 장단점과 한계점을 짚어 보며 향후 B2B 프레임웍이 나아가야 할 방향에 대해 고찰해 보고자 한다.

최근 웹 기반의 XML이 인터넷 전자거래 및 데이터 전송에 이용되고 있다. 인터넷을 통해 비즈니스 거래가 신뢰성 있게 수행되기 위해서 XML 키 관리의 중요성이 높아지고 있다. XKMS는 XML 문서를 교환하기 위해 보안을 목적으로 사용되는 암호화키의 안전한 관리를 위한 명세이다. 그러나 키의 분실 및 키 재발행 시 키의 변경에 따른 키 관리 방법에 대해서는 정의하지 않고 있다. 따라서 본 논문에서는 XKMS 표준 명세를 준수하는 키 변경에 따른 확장된 키 재발행(Extended-Reissue) 서비스를 제안한다. 제안하는 방식은 서버에 이전 사용자의 개인키를 저장하고, 키 분실 및 변경에 따른 키 재발행 시 분실키와 신규 키를 동시에 사용함으로써 효율적인 보안 서비스를 제공할 수 있다.

This paper suggests design and implementation of moving objects management system using GML which is the XML encoding standard of geographic data. The proposed system integrates spatial data and moving objects data, utilizing the concept of Web Feature Services. While integrating data, standard data model and interfaces, proposed by OGC, are used. Since GML is standard for storing and transferring spatial/non-spatial data, interoperability and extendibility can be obtained. In addition, we propose efficient developing environment for the moving object management system by providing components having Web/Mobile interface. If the proposed component be development methods are used, it is easy to add or modifyservices in the mobile system and pla

The rapid spread of Internet and network technology advances the current USN (Ubiquitous Sensor Network) in order to realize research is taking place. USN individual sensor information of the sensor nodes to provide the service is equipped with various kinds of sensors. To do this, you can use a service unspecified XML-based Web services to leverage in the standardized data representation language is needed. In this paper, the required sensor information expressed in a standardized form for USN application service was designed in the sensor data representation language. The USN-based technologies and services in the field will be utilized to activate.

Nowadays, the study is going on develop USN(Ubiquitous Sensor Network) with diffusion of the internet and development of computer network technology. USN sensor nodes equipped with various types of sensors provide sensor information to each individual sensors. To do this there needs standardized data description language for allowing many people to use based on XML in web services environment. In this paper, USN sensor information required for application services in a standardized form to describe the sensor data representation language was designed. USN-based technology utilized in the field, and will be utilized for service activation.

To access massive and various HTML documents that are in the web using wireless Internet equipments, another WML document that is equal to the HTML document must be written, In the case Web documents written by HTML are massive, the construction of a WML site with the same information needs much cost of space and time, This paper designs and implements the HTML-XML converter that alleviates such a problem. The HTML-WML converter translates the Web document written by HTML to the WML document for portable wireless equipments, The HTML-XML converter has advantages that it reconstructs WML document dynamically according to portable wireless equipments and processes various image formats such as GIF, JPG, BMP, and so on, The HTML-WML converter can be used as not only a utility of the WML editor but also a real-time converter on wireless Internet.
