Recently, researches for the integration and standardization of clinical data in the Western medicine and Korean medicine is in progress. If an integration of similar clinical data as well as heterogeneous clinical data is possible based on one standardization, we can able to derive implicit medical knowledge from integrated clinical data. In this paper, we implemented Korean clinical database based on internationally known CDISC standardization to efficiently store Korean clinical data and constructed E-CRF system for convenient data input in clinical sites. Furthermore, we showed example of an integration of Korean clinical data from 4 clinical sites. The results of our study will help to establish the foundation for the extraction of implicit medical knowledge from integrated clinical data. Also, our results may support efficient management through data integration, prevention of repetitive or unnecessary clinical trials, facilitation of collaborative study and convenient research through the distribution of refined clinical data.

The recently many corporations are using Decision Support System, such as on-line meetings. Those on-line meetings are getting grown .Because the on-line meetings with messenger and chatting are the best examples for overcoming space But, the on-line meetings have unavoidable weak points. The more a meeting is processed, the more point of argument is out of focus and perception of current situation is reduced. Therefore, this thesis proposes and describe that in think that pre-defined things , analysis and direction of Ontology ,then draw up a plan how to make ontology to knowledge, and, how to get out of bounds limitation that as make ontology to knowledge. And, design and implementation actual system that organize this ontological Knowledge, and then managing and summarizing visualizing them. Last after remark and consider this system in which using the ontology based on XML, and proposes conclusion and directional development point.

Software change is an essential operation for software evolution. To maintain the system competently, managers as well as developers must be able to understand the structure of the system but the structure of software is hidden to the developers and managers who need to change it. In this paper, we present a system (OntCIA) for supporting change impact analysis for rating and billing domain based on the semantic web technology. The basic idea of OntCIA is to build a domain knowledge base using an OWL ontology and RDF to implement change impact analysis system that would support the managers and software developers in finding out information about structure of large software system. OntCIA allows users to incrementally build an ontology in rating and billing domain and provides useful information in response to user queries concerning the code, such as, for example 'Find the modules which have a role for confirming new subscription'. The strengths of OntCIA are its architecture for easy maintenance as well as semantic indexing by automatic reasoning.

Purpose: This study was conducted to examine the changing patterns of knowledge related to disease, medication adherence, and self-management and to determine if outcomes were more favorable in the experimental group than in the comparison group through 6 months after providing a web-based self-management intervention. Methods: A non-equivalent control group quasi-experimental design was used and 65 patients with gout, 34 in experimental group and 31 in comparison group, were selected from the rheumatic clinics of two university hospitals. Data were collected four times, at baseline, at 1 month, 3 months, and 6 months after the intervention. Results: According to the study results, the changing patterns of knowledge and self-management were more positive in the experimental group than in the control group, whereas difference in the changing pattern of medication adherence between two groups was not significant. Conclusion: The results indicate that the web-based self-management program has significant effect on improving knowledge and self-management for middle aged male patients with gout. However, in order to enhance medication adherence, the web-based intervention might not be sufficient and other strategies need to be added.

A digital content have been utilized extensively without being limited to one territory of communication, computer, broadcasting, Mobile etc. A digital contents industry have been raised to a key point industry of a knowledge information society. An information infra setup of a global unit was processing to the development of Internet therefor copyright protection a digital contents and system for the officer have been desired. Like this, according as digital contents do fetters to MPEG-4 is circulated, copyright problem was risen. So, people had a lot of interests to protect and manage copyright. Hereupon, MPEG of the IS0/IEC established IPMP(Intellectual Property Management and Protection) standard, and supplements and corrects continuously standard. Therefore, existing system does fetters to MPEG-4 need system that process IPMP information. Hereupon. in this paper, designed system module that is processed by IPMP extension standard that progress now, and embodied copyright protection and management system that user can insert and update IPMP information efficiently within whole or specification part of MPEG-4 digital contents.

Shipping companies have become interested in the development of strategic ship assets management systems which are implemented for high competitiveness and business rationalization to meet the tough business environment of high oil prices and decrease in cargo. In this paper we introduce a ship assets management system that is suitable for the SAN(Ship Area Network) environment. This system is designed to execute business strategy of ship owners giving consideration to requirements of shipping stakeholders. In addition we have implemented it in a web-based ERP system (SHERP) which separates user interface and business logic. The SHERP is based on STEP and PLIB, which are international standards for data exchange of mechanical devices and parts. It also adopts a ship ontology to manage the ship information and knowledge during its life-cycle. The SHERP will be a concrete example of servitization of shipbuilding, as an information system which is used in ships and ship groups.

Purpose: The rapid change to an aging society generates an increase in the incidence of chronic diseases. Many chronic patients have been facing their illnesses without enough preparation. In order to solve these problems, we designed and tested a public healthcare service based on ubiquitous technology. Method: Telemedicine has emerged as new medical care system of chronic disease. However, public potential of its technology is difficult to know under current traditional health care system. In this work, we developed a Personal Digital Access (PDA) phone based healthcare system by trained visiting nurses for elderly patients. A field test was performed by SeongBuk Public Health Center in Seoul, Republic of Korea (ROK). Result: Surveys were generated to assess the effects of this system compared to conventional public health system. Findings of trials demonstrate that healthcare coordination enhanced by PDA phone technology is satisfactory to the patients and nurses compared to previous one because prompt responses arouse their recognition of health. Conclusion: Ubiquitous healthcare system applied to public health service proved to be efficient and time-saving to monitor and control the chronic illnesses of large population.

One of the important elements for improving academic achievement of learners in education through e-learning is to support learners to study by finding questions they want with providing various evaluation questions. However, most of question retrieval systems usually depend on keyword search based on only a syntactical analysis and/or a hierarchical browsing system classified by the topics of subjects. In such a system it is not easy to find integrative questions associated with each other. In order to improve this problem, in this paper we proposed a question management and retrieval system which allows users to easily manage questions and also to effectively find questions for study on the Web. Then, we implemented a system that gives to access questions for the domain of C language programming. The system makes it possible to easily search questions related to not only a single theme but also questions integrated by interrelationship between topics and questions. This is done by supporting to be able to retrieve questions according to conceptual interrelationships between questions from user query. Consequently, it is expected that the proposed system will provide learners to understand the basic theories and the concepts of the subjects as well as to improve the ability of comprehensive knowledge utilization and problem-solving.

The Semantic Web is a new technology that attempts to achieve effective retrieval, automation, integration, and reuse of web resources by constructing knowledge bases that are composed of machine-readable definitions and associations of resources that express the relationships among them. To have this kind of Semantic Web in place, it is necessary to have the following infrastructures: capability to assign unchangeable and unique identifier (URI) to each resource, adoption of XML namespace concept to prevent collision of element and attribute names defined by various institutions, widespread use of RDF to describe resources so that diverse metadata can be interoperable, use of RDF schema to define the meaning of metadata elements and the relationships among them, adoption of DAML+OIL that is built upon RDF(S) to increase reasoning capability and expressive power, and finally adoption of OWL that is built upon DAML+OIL by removing unnecessary constructors and adding new ones based on experience of using DAML+OIL. The purpose of this study is to describe the central concepts and technologies related to the Semantic Web and to discuss the benefits of metadata interoperability based on XML/RDF schemas and the potential applications of diverse ontologies.
