In this study, we suggest the system to analyze network users' action patterns by using Data-Mining Technique. We installed Network Tap to implement the analysis system of network action and copied the network packet. The copied packet is stored at the database through MainMemoryDB(MMDB) of the high-speed. The stored data analyze the users' action patterns by using Data-Mining Technique and then report the results to the network manager on real-time. Also, we applied the standard XML document exchange method to share the data between different systems. We propose this action pattern analysis system operated embedded type of SetToBox to install easily and support low price.

As XML is becoming a de facto standard for distribution and sharing of information, the need for an efficient yet secure access of XML data has become very important. To enforce the fine-level granularity requirement, authorization models for regulating access to XML documents use XPath which is a standard for specifying parts of XML data and a suitable language for both query processing. An access control environment for XML documents and some techniques to deal with authorization priorities and conflict resolution issues are proposed. Despite this, relatively little work has been done to enforce access controls particularly for XML databases in the case of query access. Developing an efficient mechanism for XML databases to control query-based access is therefore the central theme of this paper. This work is a proposal for an efficient yet secure XML access control system. The basic idea utilized is that a user query interaction with only necessary access control rules is modified to an alternative form which is guaranteed to have no access violations using tree-aware metadata of XML schemes and set operators supported by XPath 2.0. The scheme can be applied to any XML database management system and has several advantages over other suggested schemes. These include implementation easiness, small execution time overhead, fine-grained controls, and safe and correct query modification. The experimental results clearly demonstrate the efficiency of the approach.

EXPRESS is product information description language. It is interpretable by human and software. Product data written in EXPRESS make it possible to exchange between heterogeneous systems. However, the number of software that can use EXPRESS is limited and it is expensive to use the software. XML makes it possible to update and manage data on the Web. Because the Web is easier to use and access than other tools comparatively, data represented by XML need not depend on specific applications or systems and it can be used for exchange of data. Therefore, if we represent EXPRESS-driven data in XML, there will be more active data exchange widely and easily In this work, a method of translation EXPRESS document to XML DTD and XML Schema is proposed. By classification all of EXPRESS syntax element and consideration complex cases caused by this syntax element, a translation rule that represent XML DTD and XML Schema is suggested. Also, a translator which is corresponding to this rule is implemented.

Recently, As the managing techniques of consuming method and transmission for the sharply increasing multimedia contents has been developed regardless of compatibility by each company, It is a serious obstacle to the development of the organized copyright techniques because nothing can be shared by each other. The MPEG committee under ISO established MPEG-21 framework for it and proposed the REL as the words taking care of copyright and standardized them. However, there seemed to be some problems that special knowledge such as Schema defining the structures of XML and REL should be necessary. Furthermore, There can be some obscurity when the authority of REL document and one of consumer side is different. Therefore, in this paper, we laid out and realized the copyright including consuming system to copyright and prove the REL documents more conveniently and RDD integration system using Web Services technology which can get rid of the vagueness of REL.

유비쿼터스 헬스케어는 생체신호 측정기술과 생체신호 측정기의 소형화 경량화로 인해 의료분야의 획기적인 변화를 가져올 것으로 기대된다. 그러나 생체신호 측정 기술의 발전에 비해서 대부분의 생체신호 데이터는 각 시스템 고유의 데이터 포맷을 사용하기 때문에 사용범위가 제한되고 데이터 공유 및 호환에 어려움이 있어 구조적이며 시스템 독립적인 XML을 사용하여 생체신호 데이터를 표현하는 방법이 필요하다. 본 논문에서는 XML 기반의 HL7 Annotated ECG(HL7 aECG) 표준을 이용해서 생체신호 데이터를 표현하고 저장하는 방법을 제시한다. 제시된 방법은 ECG, 심음의 두채널 파형 정보를 포함한 바이너리 포맷을 HL7 aECG 문서로 표현하며, HL7 aECG 문서의 특성을 고려하여 비분할 저장 방식을 사용하고 효율적인 검색을 위해 메타데이터를 추출하여 관계형 테이블에 저장하는 분할 저장 방식을 병행하여 사용한다. 또한 저장된 메타데이터를 효율적으로 검색 및 관리하는 메타데이터 시스템을 설계하며 설계된 구조는 향후 다른 시스템과 연계의 가능성을 제공한다.

The email system is one of the most popular internet applications used to transmit and exchange personal information. However, the pattern of existing email system is fixed, and the system cannot be expanded or re-used. This thesis has proposed the system which can provide the users with better e-mail data which is flexible, re-usable, and expandable XML data on the web-mail. The process of change is as follows: First, make the XML data to have a tree structure using DOM API and then bring the received messages of the users with the CDONTS. Last, transform the received messages into the element and element value. When the e-mail data is transformed t the XML data, 'the data' and 'the presentation' can be distinguished, which enables the users to see messages according to each individual's unique need. With this system, the user can not only convert data to XML, but also can combine the data segments to a form of letter box in order to manage data conveniently and search the data.

XML is the most popular platform-independent data expression which is used to communicate between loosely coupled heterogeneous systems such as B2B Applications or Workflow systems. The powerful query language XQuery has been developed to support diverse needs for querying XML documents. XQuery is designed to configure results from diverse data sources into a uniquely structured query result. Therefore, it became the standard for the XML query language. Although the latest XQuery supports heavy search functions including iterations, the grouping mechanism for data is too primitive and makes the query expression difficult and complex. Therefore, this work is focused on supporting the groupby clause in the query expression to process XQuery grouping. We suggest it to be a more efficient way to process grouping for restructuring and aggregation functions on XML data. We propose an XQuery EBNF that includes the groupby clause and implemented an XQuery processing system with grouping functions based on the eXist Native XML Database.

By effect of infinity internet market copyright connection skills for extent extension of digital contents and profit rescue through this impoliticly research and develop. Contents protection techniques, management techniques, circulation techniques etc. are becoming development by contents circulation company and developers but that there is no standard as problem advances soul between copyright managerial system by development competition and in reciprocity compatibility tell. ISO MPEG commission arrived that develop MPEG-21 framework to solve problem that do that is to copyright management's opacity province that non efficiency and standard of contents distribution structure that do that is by redundancy investment are not. Data structure in Framework interior is doing and propose copyright expression language of XML base of REL to establish copyright connection data standard and normalized based on no XML. But, a tool that can be easy as must understand whole framework and can have problem in to edit REL and create copyright document fast was required. In this paper, research about method that edit REL document and develop and spend a edit tool that tan be that expressing intuitionally.

Business Process Management (BPM) is an emerging trend of managing business process life cycles and integrating heterogeneous systems . Recently, BPM is considered as an essential element for automation of complex business processes involving many companies, particularly for those in an e-Business environment. In such an environment, it is very important for each business partner to trace history of resources. However, it has been a difficult problem for Workflow Management Systems(WFMSs) to support management of resource changes because of limited storage, complex process structure, and absence of formal change model. In this paper. a new framework is proposed, which can support change management for documents, one of core resources of business process. Under a traditional WFMSs framework, all workflow components belong to either build-time or run-time function, and executions of workflow processes are performed by the two functions . To manage changes of documents while process executing. a new framework with additional component modules are required. A version control method is introduced for the purpose of managing document changes. The proposed method includes five models for document structure, process structure, association between process and document, version management, and efficient version storage. A prototype system is developed to demonstrate the effectiveness of the proposed models.
