HTML that is language that web technology is center expression these day that use of internet and quantity of information by fast development increase rapidly brought limit to use information of web and XML that express meaning or corelation of data itself in W3C by standard for free document transmission and exchange in World Wide Web by the alternative as long as is deviation appeared. There is many efforts to use storing this XML document in RDBMS but to relation style DB because XML document is tree structure structurally data SQL and perfect disaster caused by things that is language to ask a question accomplish. In this paper XML document XML informations that is stored to RDBMS via Parsing and DOM tree process SQL quality through converter called XQuery2SQL of by change and embody XQuery2SQL conversion algorithm that draw information in RDBMS.

XML Schema which enables the second revolution of Internet with XML rapidly emerging as a standard for XML document structure modeling. XML Schema modeling has more complex structures and information than DTD modeling. In this reason, XML Schema modeling tool which has some more specialized functionalities others is needed. In this paper, we have developed the XML application development method called \"Design and develop\" and implemented the prototype system named XSD4j which supports UML based XML Schema modeling and provides a XML application development platform. Using XSD4j, developers can get an easy and conceptual schema modeling method, XML storage schema for XML document, and persistent DOM API which is a standard interface between document and application program.n program.

after using dom die, this sheet pressed from a variation condition of size, of die holder power,of rpm speed, accordingly the kind of material, the conditionof deformation movement between both sheets is analyzed, is investigated in the Press machine. even if the change quantity which formed raises a blank holder pressure, the change quantity which is special is not visible from the segment where there is not a bead, the segment where there is a bead to the other side does change quantity schedule to initially and the features of press holding power which the change quantity diminishes is showed consequently from pressurization change quantity it is visible but until a rupture territory from the rpm, it goes but the features where the change quantity does not change a lot is observationd, from the CR2-sheet the quality comes out though well but a possibility of getting a result under same conditions of AL-sheet does not become the formation which stands is. It is like that though press-die which uses the drawing-sheet it exchanges the sheets, when AL-sheet with doing, the conclusion for maintain which have a formation sincerity healthy characteristic is same with afterwords.

Detailed survey of the rock mass is essential for design, construction and maintenance of rock slope. However, geological survey of poor outcrops and various geophysical aids provides limited information for slope engineering. Remote measurement system for excavation surface (Surface Mapper) and projection s/w for borehole data (Fracjection) are developed for further support of slope surveying. The Surface Mapper measures orientation of joint, fault, foliation on excavated rock surface and database the measured data. The Fracjection projects measurements in boreholes, which are obtained by BIPS, Televideo and DOM operation, to any expected excavation space. These methods promise new approaches for surveying, designing, constructing and maintaining processes of slope.

Can speak that DTD is meta data that define meaning of expressed data on XML document. Therefore, In case DTD information is damaged this information to base security of XML document dangerous. Not that attach digital signature on XML document at send-receive process of XML document in this research, proposed method to attach digital signature to DTD. As reading DTD file to end first, do parsing, and store abstracted element or attribute entitys in hash table. Read hash table and achieve message digest if parsing is ended. Compose and create digital signature with individual key after achievement. When sign digital, problem that create entirely other digest cost because do not examine about order that change at message digest process is happened. This solved by method to create DTD's digital signature using DOM that can embody tree structure for standard structure and document.

Many types of information provided through the web including news contents contain unnecessary clutters. These clutters make it difficult to build automated information processing systems such as the summarization, extraction and retrieval of documents. We propose a system that extracts and summarizes news contents from the web. The extraction system receives news contents in HTML as input and builds an element tree similar to DOM tree, and extracts texts while removing clutters with the hyperlink attribute in the HTML tag from the element tree. Texts extracted through the extraction system are transferred to the summarization system, which extracts key sentences from the texts. We implement the summarization system using co-occurrence relation graph. The summarized sentences of this paper are expected to be transmissible to PDA or cellular phone by message services such as SMS.

The objective of this research is to develop a new module which can reuse XML data by modifying the property of satellite images through the client's GUI at remote site. In order to implement this functionality, we used DOM interface which increases the efficiency of accessing the document structure, and loaded the developed GUI that could resort, retrieve and manage the satellite image list as converted XML data. The system was applied to the management system of satellite images in the Research Institute of SFC at Keio University which results in the confirmation of the technical functionalities.

PKI provides good resolutions for the authentication of user in the situation not to meet each other, but it is not enough to provide the resolution of authorization in distributed computing environments. Especially, we offer a variety forms of the user Authentication, the Integrity and a security service of the Non-Repudiation, but an authorization Policy, because of the complexity with a lot of information, using m understandable XML, makes a simple and easy certificate to read, and we get the information from DOM fee and do a XML analysis and stardardized-method usage easily In this paper, we provide the AAS model being able to use with the solution of the distributed users' authorization, and we implement an authorization policy module, using XML. in the Linux-based Apache Web server.

In this paper, we proposed an efficient document conversion mechanism to provide a adaptive web document to mobile terminals. We also proposed a RHTML(Reduced HTML) to archive the adaptive tag reduction. Markup error correction process in the proposed adaptive document conversion mechanism converts a HTML(HyperText Markup Language) document into a XML(Extensible Markup Language) application document. This. process makes web document easy to handle with a DOM (Document Object Mode)) as the tree model and removes the hardware overhead in mobile terminals. Also, tag reduction process provides the adaptive web document with three DTD(Document Type Definition)s in the RHTML.

XML will be used in lots of areas in the Web environment as a method of information exchange, We have to use dat'abases to manipulate lots of XML documents efficiently, When we use database to manipulate XML, not only type of database but also its interface is important We develop a system using relational database, object-oriented database and wrapper to store XML data, of which interfaces are XML-View, ODMG C++ binding, OQL and DOM, We discuss pros and cons of each method by the implementation of the system, and propose an efficient manipulation method of XNIL documents.
