In order to improve an efficiency of education and acquisition of PACS administor in Radiological technologist, we implement an e-Learing databank system providing more efficiently provide medical questions set for the integrated education and PACS administor without the limitation of time and space based on XML that is the standard of exchange and transmission of Web documents via Internet. The proposed system is composed of administration module and user module. The former supports some functions: a creation, classification, and management of Radiological question set. Our system can elevate ability of learning and interchange of information among Radiological technologist making preparation of PACS administor for Radiological technologist examination. Finally, our system can maximize an effectiveness of education by evaluating and training users individually with various level according to the user's ability of learning and realization.

A standard Web server or web application servers require the Web Servlet container to execute SOAP messages. But it requires additional process to make web service modules and need communication port. Also, Recently many web applications is becoming increasingly demand against the dynamic document than the static documnet. But a recent study has found that Apache Web Server always does not show the better performance. The more it have the dynamic documents, rather it can show worse performance. To solve this problem, we propose a new High-Speed Message Processing System, in which the SOAP_MP and the WSDL builder are used. The WSDL builder convert HTML/XML to WSDL files automatically and the SOAP_MP minimize SOAP massage processing time by eliminating the Tomcat Servlet container in the mobile Web Services implementation. We compare and analyze the System, which was proposed by us, with the standard Web Service system.

To automate nuclear design works which are time-consuming and man-power intensive, Innovative Design Processor ($IDP^{TM}$) is being developed. Two basic principles of IDP are the document-oriented design and the web-based design. The document-oriented design is that, if the designer writes a design document called active document and feeds it to a special program which has a robust parser, the finai document with complete analysis, table and plots is made automatically. The active documents can be written with ordinary HTML/XML editors or created automatically on the web, which is another framework of IDP. Using the proper mix-up of server side and client side programming under the LAMP (Linux/Apache/MySQL/PHP) environment, the design process on the web is modeled as a design wizard style so that even a novice designer makes the design document easily.

In this paper, we propose a system for analyzing documents in XML format and in reports. The system extracts the paper or reports of keywords, shows them to the user, and then extracts the paragraphs containing the keywords by inputting the keywords that the user wants to search within the document. The system checks the frequency of keywords entered by the user, calculates weights, and removes paragraphs containing only keywords with the lowest weight. Also, we divide the refined paragraphs into 10 regions, calculate the importance of the paragraphs per region, compare the importance of each region, and inform the user of the main region having the highest importance. With these features, the proposed system can provide the main paragraphs with higher compression ratio than analyzing the papers or reports using the existing document analysis system. This will reduce the time required to understand the document.

We present X-tree Diff, a change detection algorithm for tree-structured data. Our work is motivated by need to monitor massive volume of web documents and detect suspicious changes, called defacement attack on web sites. From this context, our algorithm should be very efficient in speed and use of memory space. X-tree Diff uses a special ordered labeled tree, X-tree, to represent XML/HTML documents. X-tree nodes have a special field, tMD, which stores a 128-bit hash value representing the structure and data of subtrees, so match identical subtrees form the old and new versions. During this process, X-tree Diff uses the Rule of Delaying Ambiguous Matchings, implying that it perform exact matching where a node in the old version has one-to one corrspondence with the corresponding node in the new, by delaying all the others. It drastically reduces the possibility of wrong matchings. X-tree Diff propagates such exact matchings upwards in Step 2, and obtain more matchings downwsards from roots in Step 3. In step 4, nodes to ve inserted or deleted are decided, We aldo show thst X-tree Diff runs on O(n), woere n is the number of noses in X-trees, in worst case as well as in average case, This result is even better than that of BULD Diff algorithm, which is O(n log(n)) in worst case, We experimented X-tree Diff on reat data, which are about 11,000 home pages from about 20 wev sites, instead of synthetic documets manipulated for experimented for ex[erimentation. Currently, X-treeDiff algorithm is being used in a commeercial hacking detection system, called the WIDS(Web-Document Intrusion Detection System), which is to find changes occured in registered websites, and report suspicious changes to users.

Development of hospital information system and Picture Archiving Communication System is not new in the medical field, and the development of internet and information technology are also universal. In the course of such development, however, it is hard to share medical information without a refined standard format. Especially in the department of radiology, the role of PACS has become very important in interchanging information with other disparate hospital information systems. A specific system needs to be developed that radiological reports are archived into a database efficiently. This includes sharing of medical images. A model is suggested in this study in which an internal system is developed where radiologists store necessary images and transmit them in the standard international clinical format, Clinical Document Architecture, and share the information with hospitals. CDA document generator was made to generate a new file format and separate the existing storage system from the new system. This was to ensure the access to required data in XML documents. The model presented in this study added a process where crucial images in reading are inserted in the CDA radiological report generator. Therefore, this study suggests a storage and transmission model for CDA documents, which is different from the existing DICOM SR. Radiological reports could be better shared, when the application function for inserting images and the analysis of standard clinical terms are completed.

Web applications based on J2EE($Java^{TM}$ 2 Platform, Enterprise Edition) were occurred for solution to overcome the limitations in time and space that the former applications had. Recently, lots of solutions using frameworks are being suggested to develope applications more quickly and efficiently. In this paper, we propose the template for several processes and types, which should be taken in presentation layer of web applications. This idea was based on the fact that web applications developers can concentrate on their specific tasks with independent manner in layered architecture. This template is XML-typed document that shows information about presentation layer of Web applications, which the user wants to compose. This template is inputted to the code generator. After then, the code generator generates skeleton code in presentation layer automatically after parsing information of XML documents. It means that we can develope Web applications more efficiently, by constructing skeleton code which inherits from hot spot classes of framework. Using this template and code generator, developer can develop Web applications with little practice and also is easy to cooperate with other developers to develop them just in time with distributing the standard development process.

The National Education Information System (NEIS), one of ERP systems developed by Ministry of Education & Human Resources Development, has been utilized in primary and secondary schools. In this paper, we considered the NEIS should be used not only for educational administration affairs, but also for a lifelong management of National Human Resource. The current School Information Management System (SIMS) is unsatisfactory due to the insufficiency of actual field suitability and user's conveniency. For solving such problems, the system rebuilding or revision should be accompanied by. As a guideline of revision and supplement of the SIMS, we suggest an application useful in both schools and clinics by the integrating healthcare management information of people. For this, we propose a lifelong healthcare information management by integrating Student Health Records of the NEIS with Electronic Medical Records of doctors' offices. The healthcare information is designed and represented in XML. We applied different XSL style-sheets to XML documents in order to offer a view suitable for demands of schools and clinics. The healthcare information can be managed and utilized efficiently by using the view. We ascertained that the lifelong Healthcare Information Management System is an improvement to overcome the inefficiency of healthcare information management and the connection inadequacy between schools and medical institutions, and is desirable for a lifelong management of the National Human Resource.

The Web plays an important role as information source and most Web applications are document-centric. A document implies an intention of its own designer, which can be utilized actively in automation of business processes. Through an understanding of an intrinsic nature of a document function, we can see a document as an executable computer program in a special case. For this approach, we propose an active document model that is composed of form, knowledge base, rules, and queries. For reusability and interoperability of a document, each component of the proposed model is uniformly represented in XML. The proposed active document not only plays a passive role in providing user interfaces, but also is a document that a machine can infer and process with reading a procedure of document processing and business rules intended by document designers. Through this approach, document can interact with machines and can cooperate with other applications. For applicability of our active document, we show a case study for the processing of purchase orders in a B2B e-Commerce system. This paper is expected to provide the framework of accelerating the development of intelligent applications through our approach regards form document as a computer program. In short, the proposed active document contains knowledge representation and processing method, consequently our document will play an important role in providing a concept of document of pursuing in Semantic Web.

SOAP using WSDL(Web Service Definition Language) was proposed for effective integration of distributed objects. But the SOAP message and WSDL document automatically generated from development tool are fully dependent on the development environments. So the dependency of SOAP messages and WSDL documents for objects to the development environment is still a big problem to be solved for the integration of heterogeneous distributed objects. In order to support integration of heterogeneous distributed object, we implemented SOAP Bridge called WBSB(WSDL Based SOAP Bridge). As service request message for a particular service object is translated into appropriate SOAP message for the selected service object by WBSB using WSDL repository, a client can use service object without considering the development environment of the service object.
