With the spread of internet, the digitalization and the knowledge informatization are in progress rapidly. Specially, numerous users make the various works and use the services on the web. For the most part, these works make use of the XML The XML shines the reusing of the documents because it is separated from contents and sues. Also, it can re-define the logic structure of the document for requirement of the developer. However, the XML document’s size is much larger than common text document because it handles the document type and adds numerous tags for representing structure of the document. To utilize the limited storage devices of Palmtop, PDA and so u, it is necessary to compress and handle the documents efficiently. Recently, the compression techniques for efficiently handling and compressing the XML documents are under way to solve this problem. But most of the existing researches don't support the query processing for the compressed XML documents. In this paper, we design and implement the XML compression algorithm that compresses the XML document and Processes the query of compressed XML document faster and more efficiently than previous techniques.

In this paper, we have studied the technical contribution of internet as a computer mediated communication(CMC) tool for collection management. A new communication process is appearing due to the development of information technology and telecommunications technology which enable users to have an access to information without the help of librarian. Also, internet makes collection management possible in the absence of vendors. This study found out that internet reinforces the traditional functions of collection management and enables librarians to better perform their roles. The future library manager should become actively involved in the development of technology in order to manage resources of internet focusing on the needs of user. Also, we have concluded that collection management should be modernized and transformed with its emphasis on the new evaluation method and assessment of quality when offering resources of internet in the communication process using computers.

The purpose of this study was to investigate the effect of mobile task information presentation using 3D multimedia on tooth carving knowledge, performance and class satisfaction for dentistry. To accomplish this purpose, we divided 66 dental students into the two groups: The experimental group was presented with mobile task information using 3D modeling. and the control group was presented task information using textbook. As a result for the study, First, Mobile task information presentation using 3D multimedia in class has significant effect on the tooth carving performance and class satisfaction. Second, tooth morphology knowledge in control group presenting task information using the text book showed relatively higher than in experimental group which presenting mobile task information using the 3D modeling. The conclusion of this study is that the class presenting mobile task information using 3D modeling can be enhances class satisfaction and, teaching and learning strategy to improve tooth carving performance.

The purpose of this study is to suggest a writing education paradigm appropriate for the ideology and ideal persons of Christian universities, and to show the effective application plan. For this, this study utilizes the ideas of digital writing in the concept of digital literacy education. The paradigm of "the digital writing education using bible storytelling" consists of two activities. The first one is 'bible listening and observation,' and the second one is 'media text creation and sharing'. In the first activity, there are two steps: 'listening and observation of bible storytelling' and 'exploration and meditation.' In the second activity, there are also two steps: 'application and action,' and 'sharing in communities.' After the suggestion, this study proposes the application plan for the paradigm. They are 'the utilization of various media and the merit of interaction,' healing effectiveness in an individual and a community,' 'building expertises in both letter writing and Christian education(Divinity),' 'building expertises in both letter writing and media literacy,' and 'expanded application toward diverse patterns of writing.'

This study examined contents of interaction that played an important role in learners' accomplishment of educational goals at web-based educational system. The purpose of the study was to find out design strategies of web-based education website that could give learners more satisfactory interaction. The study firstly investigated concept and values of web-based education as well as interaction by literature study to analyze web-based educational design principles at actual web-based education websites from point of view of interaction and to examine what factors should be used and reinforced at existing teaching. The findings were as follow: Web-based education websites made use of interaction with 'each design factor', such as colors, texts and images, etc that were based on communication designs to give 'information' by systematic interaction more than by social interaction.

The purpose of this study is to suggest web accessibility improvement direction through web accessibility evaluation of 16 local government education and training institutions. For this purpose, we evaluated the websites of 14 education and training institutions excluding some websites. The evaluation was conducted through automatic evaluation by Open-WAX and manual evaluation by three experts. As a result of the analysis, although the web accessibility compliance rate improved, problems such as alternate text, skip link, and markup error prevention were found. This study suggests the future direction of research and adherence to web accessibility of local governments.

In this paper, we propose a method of retrieving opinioned tweets in Twitter, which is the one of the popular Social Network Services and shares diverse opinions among various users. In typical opinion retrieval systems, they may consider the presence of sentiment phrases (subjectivity) as the important factor even if the subjective phrases are not related to a given query or speaker. To alleviate these problems, we utilized the syntactic structure of a sentence to identify the relationships between 1) subjectivity-query and 2) subjectivity-speaker and 3) the syntactic role of subjectivity. Besides, our learning-to-rank approach is trained to retrieve opinioned tweets based on query-relevance, textual features, user information, and Twitter-specific features. Experimental results on real world data show that our proposed method can achieve better performance than several baseline methods in terms of precision and nDCG.

Currently, oriental medicine research is focused with modern research technology and validate it's various biochemical effect by combining with molecular biology technology. But there are few searching system for finding biochemical mechanism which is related to major compounds in oriental medicine. In this research, we aimed developing korean herb database based on text-mining system by analyzing PubMed data. We have developed prototype system for searching chemical, gene and biological relation in oriental medicine. It is characterized by modern oriental medicine research trend with major chemical, gene and protein information. Analysis results can be searched on the prototype system with visualization of the biological interactions.

In this study, HRD-NET (http://hrd.go.kr), a vocational and training integrated computer network operated by the Ministry of Employment and Labor, is used to confirm whether job training information required by job seekers is being provided smoothly The question bulletin board was extracted using 'R' program which is optimized for big data technique. Therefore, the effectiveness, appropriateness, visualization, frequency analysis and association analysis of the vocational training system were conducted through this, The results of the study are as follows. First, the issue of vocational training card, video viewing, certificate issue, registration error, Second, management and processing procedures of learning cards for tomorrow 's learning cards are complicated and difficult. In addition, it was analyzed that the training cost system and the refund structure differentiated according to the training occupation, the process, and the training institution in the course of the training. Based on this paper, we will study not only the training system of the Ministry of Employment and Labor but also the improvement of the various training computer system of the government department through the analysis of big data.
