전자책(eBook)은 디지털 매체를 이용해 책의 내용을 저장 및 가공한 출판물을 의미하며 저장의 용이성과 휴대가능성 및 검색 등의 장점을 가지고 있다. 이러한 장점을 가진 전자책은 아직 전용 소프트웨어가 미비한 상태이며 먼저 전자책을 저작하는 전용 편집기의 개발로 먼저 전자책의 저작이 이루어져야 한다. 본 논문은 장르별 구조를 제공하는 폼 기반(Form-based)의 전자책 편집기를 제안하며 특히 전자책의 특성상 사용자가 기본적으로 제공되는 폼에 더하여 구조를 동적으로 추가할 수 있는 유연성 있는 폼을 지원하는 시스템을 구현하였다. 본 편집기는 국내 전자책의 표준 포맷인 XML(extensible Markup Language)을 기반으로 하였다. 따라서 본 시스템에서 제공되는 폼으로서 사용자는 XML 구조의 숙지 없는 쉬운 인터페이스와 사용자의 의도에 따른 구조 제공으로 장르별 전자책을 작성하기에 용이하였다.

북한에서 운영하고 있는 오피스 프로그램인 서광사무처리 3.0은 ODF(Open Document Format) 파일 포맷을 입력으로 받아 문서를 처리한다. ODF는 여러 개의 XML(Extensible Markup Language) 파일로 구성되어 있고, 하위 노드들을 통해서 파일 구조를 정의한다. 이러한 서광사무처리 3.0의 ODF 파일 구조를 하위 프로그램별 입력받는 파일 확장자에 따라 공통 영역과 가변 영역으로 비교하고, CVE(Common Vulnerabilities and Exposures)를 통해 ODF와 XML 주요 취약점을 분석한다.

Today's computing system has expanded its application to business trade and distributed work transactions using the Internet. As the demand for more flexible, adaptable, extensible, and robust web-based enterprise, these application development has been gradually expanded based on reusable, independent, and portable components. Component Based Development (CBD) works by developing and evolving software from selected reusable software components and then assembling them within appropriate software architecture. However, it requires an increase in cost to build new components as well as the necessary effort to develop of the business requirement these components. Standardized component models are required as well from the perspective of systems in order to support rapid and exact component information transmission on the web. In this paper, we describe the e-Business Component Development with agent for rapid application development on the web that correspond to the demands of users in the business domain. We design and implement the specifications of e-business components by combining these demands. In order to improve the agent register and retrieval, we propose the intelligent search and register agents, which can conduct more precise searching and specializing for components. The system enables the locating of user's frequently used components through an agent involving register and retrieval, as well as rapid procedures for registers The e-BCOS (e-Business Component System) is the agent system for the user to register distributed components and to search for components Information. The e-BCOS increases reusability through the e-business component development of distributed components in the business domain. For the share and delivery, specification with XML is acceptable to user's variable order e-BCOS Includes the effective investment, timeliness, reliability, efficiency, and maintenance effort by with agent.

The success of XML(eXtensible Markup Language) is primarily based on its flexibility : everybody can define the structure of XML documents that represent information in the form he or she desires. XML is so flexible that XML documents cannot be automatically provided with an underlying semantics. Different tag sets, different names for elements or attributes, or different document structures in general mislead the task of classifying and clustering XML documents precisely. In this paper, we design and implement a system that allows checking the semantic-based similarity between XML tags. First, this system extracts the underlying semantics of tags and then expands the synonym set of tags using an WordNet thesaurus and user-defined word library which supports the abbreviation forms and compound words for XML tags. Seconds, considering the relative importance of XML tags in the XML documents, we extend a conventional vector space model which is the most generally used for document model in Information Retrieval field. Using this method, we have been able to check the similarity between XML tags which are represented different tags.

This paper presents the development method of educational simulator for Power System Analysis. The developed simulator can be made the students to model, analysis of power systems by drawing the system and performing the load flow, fault analysis by themselves under window environment. The simulator has developed by using the language based on XML(extensible Markup Language). Therefore, we determine that this simulator is useful to educate the load flow and fault analysis.

With the advent of the international standard IEC 61850 for communication networks and systems in substations, utilities are beginning to implement substation automation systems (SAS) that can give support to interoperability, interchangeability and self-description features. This paper describes with the SAS design accordance with this new standard. After a brief introduction of IEC 61850 SCL, this paper addresses some issues related to the specification of an IEC 61850 based SAS, and describes the Substation Configuration Language (SCL) based on Extensible Markup Language (XML). The SAS design process is explored with examples including the Intelligent Electronic Device (IED) selection, Logical Nodes (LN) allocation and the related services and the SAS communication architecture.

XML(extensible Markup Language) is effective to information retrieval and sharing but has defects related to the data security. And, as a solution of this problem, the current XML security researches such as XML digital signature, XML data encryption, and XML access control exclude the validation property of XML document. The validation of XML should be considered for the secure information sharing in the XML-based environment. In this paper, we design and implement the system to support both security and validation to XML document. Our system performs data encryption and maintenance of valid status of XML document by referencing new XML schema namespace. In addition, it also provides the XML schema security function through the XML schema digital signature. During generating XML schema digital signature, DOMHash method which has the advantage of the faster speed than canonical XML method is applied to XML schema. In conclusion, our system shows the improved functions in flexibility, scalability, and reliability compared with the existing XML security researches.

Recently, business integration and interoperability of between the heterogeneous applications are requested by rapid growth of web. Web Services that self-contained for platform and programming language is appeared used to XML of standard data format. Such amid Fast Web Services attract attention at fields necessary to bring rapid communication like Mobile and RFID. In this paper, we inquired about ASN.1 of ITU-T and IS0/IEC standard that a central role of data transform. And we studied encoding process of between ASN.1 and XML for transform SOAP massage of a massage transfer mode of Web Services to binary data.

In this paper, we focus on efficient construction of tightest matched subtree (TMSubtree) results, for keyword queries on extensible markup language (XML) data, based on smallest lowest common ancestor (SLCA) semantics. Here, "matched" means that all nodes in a returned subtree satisfy the constraint that the set of distinct keywords of the subtree rooted at each node is not subsumed by that of any of its sibling nodes, while "tightest" means that no two subtrees rooted at two sibling nodes can contain the same set of keywords. Assume that d is the depth of a given TMSubtree, m is the number of keywords of a given query Q. We proved that if d ${\leq}$ m, a matched subtree result has at most 2m! nodes; otherwise, the size of a matched subtree result is bounded by (d - m + 2)m!. Based on this theoretical result, we propose a pipelined algorithm to construct TMSubtree results without rescanning all node labels. Experiments verify the benefits of our algorithm in aiding keyword search over XML data.
