  • The nuclear design analysis requires time-consuming and erroneous model-input preparation. code run. output analysis and quality assurance process. To reduce human effort and improve design quality and productivity. Innovative Design Processor (IDP) is being developed. Two basic principles of IDP are the document-oriented desigll 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. the final document with complete analysis. table and plots is made automatically. The active documents can be written with Microsoft Word 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. it e design process on the web is modeled as a design wizard style so that even a novice designer makes the design document easily. This automation using the IDP is now being implemented for all the reload design of Korea Standard Nuclear Power Plant (KSNP) type PWRs. The introduction of this process will allow large reduction in all reload design efforts of KSNP and provide a platform for design and R&D tasks of KNFC.

  • XML is the new universal format for structured documents and data on the World Wide Web. As the Web becomes a major means of disseminating and sharing information and as the amount of XML data increases substantially, there are increased needs to manage and design such XML document in a novel yet efficient way. Moreover a demand of XML Schema(W3C XML Schema Spec.) that verifies XML document becomes increasing recently. However, XML Schema has a weak point for design because of its complication despite of various data and abundant expressiveness. Thus, it is difficult to design a complex document reflecting the usability, global and local facility and ability of expansion. This paper shows a simple way of modeling for XML document using a fundamental means for database design, the Entity-Relationship model. The design from the Entity-Relationship model to XML Schema can not be directly on account of discordance between the two models. So we present some algorithms to generate XML Schema from the Entity-Relationship model. The algorithms produce XML Schema codes using a hierarchical view representation. An important objective of this modeling is to preserve XML Schema's object-oriented concepts such as reusability, global and local ability. In addition to, implementation procedure and evaluation of the proposed design method are described.

  • 최근 다양한 분야에서 폭넓게 활용되고 있는 XML 문서는 유연하고도 개방적인 특성으로 인해 정보교환이나 전송을 위한 수단으로 널리 이용되고 있다. 한편 XML 문서를 위한 시각적, 직관적 질의 언어인 XML-GL은 질의에 대한 의미와 결과 문서의 구조를 시각적으로 표현할 수 있기 때문에 XML 문서에 대한 구조 검색과 정보의 공유가 용이하다. 그리고 UML은 정해진 표기법과 다양한 다이어그램을 이용하여 객체지향 분석과 설계를 위한 도구로 사용되고 있다. 따라서 본 논문은 XML-GL의 데이터 모델인 XML-GDM을 기반으로 표현된 XML 문서를 UML 클래스 다이어그램으로 사상하기 위한 새로운 객체 모델링 방안을 제안한다. 이를 통해서 XML 문서를 직관적인 방법으로 객체지향데이터로 변환하고 저장/관리할 수 있다. 또한 객체지향 검색방법을 적용하면 보다 효율적으로 XML 문서를 검색할 수가 있다.

  • Documents in a traditional PDM(Product Data Management) system have been managed in a form of scanned document files or electronic documents developed by specific tools. Though each tool manages documents with its own systematical methods, it has drawbacks in data search, data integration and interchange, etc. For this reason, in this research we propose an efficient document management system for PDM by using the SGML(Standard Generalized Markup Language), one of CALS and ISO standards for document interchanges. Among documents to be managed in PDM, the engineering change notification (ECN) is taken into account. The DTD (Document Type Definition) has been constucted based on the logical analysis of the documents format, In addition, based on the DTD, DB classes have been designed by object-oriented paradigms and a prototype for document input/output and search has been developed using UniSQL ORDBMS (Object-Relational DBMS) and PowerBuilder under the client/server environment.

  • As XML emerging as the Internet electronic document language standard of the next generation, the number of XML documents which contain vast amount of Information is increasing substantially through the transformation of existing documents to XML documents or the appearance of new XML documents. Consequently, XML document retrieval system becomes extremely essential for searching through a large quantity of XML documents that are storied in and managed by DBMS. In this paper we describe the design and implementation of BADA-IV/XML query processor that supports content-based, structure-based and attribute-based retrieval. We design XML query language based upon XQL (XML Query Language) of W3C and tightly-coupled with OQL (a query language for object-oriented database). XML document is stored and maintained in BADA-IV, which is an object-oriented database management system developed by ETRI (Electronics and Telecommunications Research Institute) The storage data model is based on DOM (Document Object Model), therefore the retrieval of XML documents is executed basically using DOM tree traversal. We improve the search performance using Node ID which represents node's hierarchy information in an XML document. Assuming that DOW tree is a complete k-ary tree, we show that Node ID technique is superior to DOM tree traversal from the viewpoint of node fetch counts.

  • 전자 문서로의 XML의 가치는 날로 증대하고 있다. XML 문서는 반구조적인 특징을 가지고 있으며, 객체지향 데이타베이스는 이를 모델링하기에 적합하다. 기존 데이타베이스 시스템에 저장하기 위하여 XML 문서의 DTD 정보를 이용하여 스키마를 생성하는 방법은 많이 연구되어 왔다. 본 논문에서는 XML 문서의 의미적인 정보를 보존하는 방법으로 XML 문서를 객체지향 데이타베이스에 저장하였다. 이를 통하여 OQL, C++ 바인딩과 같은 객체지향 데이타베이스의 기능을 활용하여 XML 문서에 대한 검색 등이 가능하게 되었으며, 기존 객체지향 데이타베이스 응용 프로그램을 그대로 사용할 수 있게 하였다.

  • 최근 인터넷의 폭발적인 성장과 인기로 인하여 인터넷을 통한 정보 교환이 극적으로 증가하고 있다. 또한 XML은 인터넷상에서 데이터를 교환하기 위한 표준인 동시에 중요한 수단이 되고 있다. 따라서 XML 문서를 검색하는데 있어서, 경로-지향 질의에 대한 평가 속도를 개선하는 문제는 중요한 이슈이다. 본 논문에서는 문서 데이터베이스에서 경로-지향 질의의 검색 성능을 개선하기 위한 새로운 인덱싱 방법을 제안하다. 새로운 인덱싱 방법에서는 경로-지향 질의를 효과적으로 수행하기 위해 단축-경로 파일을 생성하고 그것의 해시 코드 값을 인덱스 키로 사용한다. 또한 검색 평가 속도를 촉진시키기 위하여 단축-경로 파일을 확장성 해싱 기법과 결합하는 것으로 검색질의의 평가속도를 가속화하였다.

  • Development of IT technology, in combination with the medical area, a number of developments have been made of the digital advanced medical devices, also increased interest in health, sharing of medical information has become increasingly necessary. Standardization for medical information sharing to satisfy these requirements have been studied. However, the medical information system is to build a system independent hospital itself, is difficult to share and exchange medical data with other medical institutions. In this paper, we provide a medical cloud system that can share medical information. Use DBaaS of cloud services. And is an international standard to have a HL7 share information by forming a meta-schema, each of the data transfer, the format of the document oriented data solves the heterogeneity between hospitals. Extracts the required field name of examination information, to exchange information with each of the local information and mapping. Health diagnostic information in the present study and diagnosis through accurate information sharing and exchange is possible ongoing management.

  • Graph-based document models have good capabilities to reveal inter-dependencies among unstructured text data. Natural language processing (NLP) systems that use such models as an intermediate representation have shown good performance. This paper proposes a novel fuzzy graph-based document model and to demonstrate its effectiveness by applying fuzzy logic tools for text summarization. The proposed system accepts a text document as input and identifies some of its sentence level features, namely sentence position, sentence length, numerical data, thematic word, proper noun, title feature, upper case feature, and sentence similarity. The fuzzy membership value of each feature is computed from the sentences. We also propose a novel algorithm to construct the fuzzy graph as an intermediate representation of the input document. The Recall-Oriented Understudy for Gisting Evaluation (ROUGE) metric is used to evaluate the model. The evaluation based on different quality metrics was also performed to verify the effectiveness of the model. The ANOVA test confirms the hypothesis that the proposed model improves the summarizer performance by 10% when compared with the state-of-the-art summarizers employing alternate intermediate representations for the input text.
