전자상거래는 많은 오프라인 상업적 거래를 대신 처리하기 위해 널리 사용되어진다. 그러나 전자상거래를 통한 거래를 시도하는 사람들은 상품의 기능, 가격에 대한 문의, 구매 후 절차 등 상품 및 구매에 대한 정보를 획득하는 방법에 대하여 어려움을 느끼는 수가 많다. 본 시스템은 온라인 상에서 상품을 선택하고 구매하는 것에 대해 도움을 원하는 구매자들에게 대화형 상담 도구를 제공한다. 도구는 고객들과 판매 상담자들 사이에 대화형 상담을 지원하며, 특히 판매 상담자들은 브라우저 에스코팅과 텍스트 채팅을 통하여 다수의 고객들과 실시간 동시 통신을 하게 된다.

XML is a standard for data expression and conversion on internet, and we need a XML document search system to find necessary information contained in XML documents. In this research, we developed a XML document searching system that find the most similar documents both in structure and content for given XML documents while making the best use XML structure. The search metrics used considers the similarity for each of tag's name, the similarity for the values included each tag, and the similarity for the structure among tags of XML documents. After searching, it displays a ranking of the calculated similarity result. The system provides three query methods of a search method using keyword,using tags and values, using a XML document. The three query methods support the choice of user search requirements to promote the usefulness of our system. We tested our system for XML documents provided by INEX.

Extensible Markup Language (XML) is an Internet standard that is used to express and convert data. In order to find the necessary information out of XML documents, you need a search system for XML documents. In this research, we have developed a search system that can find documents that matches the structure and content of a given XML document, making the best use of XML structure. Search metrics take account of the similarity in tag names, tag values, and the structure of tags. After a search, the system displays the ranked results in the order of aggregate similarity.

With internet technology, e-learning gradually replace the off-line learning. For an e-learning class, many voice and video technics for enhancing student teacher interaction. But for programming exercise courses, it's very difficult to add interactive components via web browser. In this paper, we make and online algorithm bank to manage and search algorithms, build and programming exercise interface on web. Students can edit, compile and execute programs included in online algorithm bank. We also animated some representative programs like sorting, tree traversal, graph traversal, to help student understand those algorithms easily. Online program compile and execution enhance e-learning effectiveness for programming courses and make students feel ease for computer algorithms.

Reverse gyrase is a hyperthermophile specific protein which introduces positive supercoils into DNA molecules. Reverse gyrase consists of an N-terminal helicase-like domain and a C-terminal topoisomerase domain. The helicase-like domain shares the three-dimensional structure with two tandem RecA-folds (H1 and H2), in which the subdomain H2 is interrupted by the latch domain (H3). To understand the physical property of the hyperthermophile-specific protein, two subdomains af_H1 and af_H23 have been cloned into E. coli expression vector, pET28a. The 15N-labeled af_H1 and af_H23 proteins were expressed and purified for heteronuclear NMR study. The af_H1 protein exhibits the well-dispersion of amide signals in its 1H/15N-HSQC spectra and thus further NMR study continues to be progressed.
NMR Study on the Preferential Binding of the Zα Domain of Human ADAR1 to CG-repeat DNA Duplex

The Z-DNA domain of human ADAR1 (ZαADAR1) produces B-Z junction DNA through preferential binding to the CG-repeat segment and destabilizing the neighboring AT-rich region.9 However, this study could not answer the question of how many base-pairs in AT-rich region are destabilized by binding of ZαADAR1. Thus, we have performed NMR experiments of ZαADAR1 to the longer DNA duplex containing an 8-base-paired (8-bp) CG-repeat segment and a 12-bp AT-rich region. This study revealed that ZαADAR1 preferentially binds to the CG-repeat segment rather than AT-rich region in a long DNA and then destabilizes at least 6 base-pairs in the neighboring AT-rich region for efficient B-Z transition of the CG-repeat segment.
