World practice is evidence of that computer systems of an intellectual support of medical activities bound up with examination of patients, their diagnosis, therapy and so on are the most effective means for attainment of a high level of physician\`s qualification. Such systems must contain large knowledge bases consistent with the modern level of science and practice. To from large knowledge bases for such systems it is necessary to have a medical ontology model reflecting contemporary notions of medicine. This paper presents a description of an observation ontology, knowledge base for the physician of general tipe, architecture, functions and implementation of problem independent shell of the system for intellectual supporting patient examination and mathematical model of the dialog. The system can be used by the following specialist: therapeutist, surgeon, gynecologist, urologist, otolaryngologist, ophthalmologist, endocrinologist, neuropathologist and immunologist. The system supports a high level of examination of patients, delivers doctors from routine work upon filling in case records and also automatically forms a computer archives of case records. The archives can be used for any statistical data processing, for producing accounts and also for debugging of knowledge bases of expert systems. Besides that, the system can be used for rise of medical education level of students, doctors in internship, staff physicians and postgraduate students.

의료 분야에서는 질병의 진단과 치료를 목적으로 하는 지식베이스 구축에 관심이 높다. 이러한 목적의 지식베이스를 구축하는데 가장 중요한 것은 정확하게 지식을 표현하는 것이다. 본 논문에서는 온톨로지를 이용해 최근 의료 분야에서 많은 관심을 받고 있는 알츠하이머 질병과 관련한 국내 논문들을 대상으로 지식을 표현하는 방법을 제안하였다. 본 논문에서 제안한 온톨로지 기반 지식 표현 방법은 저자, 발행기관 등과 같은 서지 정보에서 추출한 클래스들은 물론 논문의 제목, 초록, 키워드, 결론에서 추출한 연구 주제와 관련된 클래스들을 모두 정의하고 프로퍼티를 통해 클래스들간의 다양한 의미적 관계를 포함하고 있다. 그리고 클래스들간의 계층 관계와 프로퍼티의 이행적 특성도 포함하고 있기 때문에 이를 이용한 추론을 지원한다. 따라서 단순한 키워드 검색뿐만 아니라 의미에 기반을 둔 지식 검색이 가능하다. 또한 온톨로지 검색 언어인 SPARQL을 이용해 추론을 통한 지식 검색 요청을 보다 쉽게 표현할 수 있다.

U-Healthcare는 홈 네트워크, 휴대용 장치 등에 기반한 정보통신기술과 의료시스템이 서로 융합되어 개인의 생체정보 등을 실시간으로 모니터링하고, 자동으로 병원 및 의사와 연결되어 시공간의 제약을 줄임으로써 언제 어디서나 건강을 관리하고 질병을 예방하는 새로운 형태의 의료서비스이다. 본 논문에서는 진료 중심에서 예방 중심으로 변화되어가고 있는 최근의 U-Healthcare 시스템의 기술 발전 추세에 맞추어 조기 대응이 가능한 Healthcare 정보시스템 구축을 위한 요구분석 사항들에 대해 정리하고, 이를 기반으로 u-Healthcare의 실현을 위한 기존의 단위 시스템인 PACS, OCS, EMR, 응급의료시스템을 통합한 환자중심의 클라이언트 시스템을 설계한다. 특히, 온톨로지는 특정분야의 정보 모델에 이용되어 그 분야에서 공통의 어휘를 제공하고, 그 용어의 의미와 용어간의 관계를 다양한 수준의 형식성을 가지고 제공한다. 본 논문에서는 이러한 온톨로지 및 무질서한 데이터에 대한 관계를 정의하고, 보다 체계적으로 데이터를 군집화하는 클러스터링의 개념을 포함한 환자중심의 서비스를 위한 온톨로지 기반의 시스템을 제안한다.

This paper proposes an ontology-based context-aware home healthcare platform employing environmental factors obtained from home. The proposed platform manages the health of home residents, and notifies relatives or a medical team of critical condition through context-awareness based on home ontology by using information sensed from various sensors. The ontology definition of context-awareness from the sensed information provides technically more precise decision for us. Therefore the platform can be aware of the health state of residents and environment by reasoning exactly from data gathered from various sensors and heterogeneous devices. The platform also can individually provide the customized service for users by setting priority for critical status that can be occurred in the health state of residents.

With the development of information technology, knowledge information-oriented and information systems are being rapidly paced. In addition, doctor's needs of the system that assist decision making is gradually increasing. Because the complex process of decision-making should be a lot. We propose a web based system for supporting medical treatment based on Korean medicine ontology. There are three kinds of processes. First, a pattern is decided for patient' symptoms, a formula for the pattern is selected and medicinal materials constituting the formula is added or removed. Second, a formula is decided for patient' symptoms, medicinal materials constituting the formula is added or removed. Third, a Treat method is decided for patient' symptoms, medicinal materials constituting the formula is added or removed. We have designed and implemented the clinical decision support system that supports flexible processes and necessary information and functions. The system shows the appropriate form of ontology knowledge as interrelated and provide analysis and processing, does not show simply search. The system is one of the systems utilizing ontology and a web based system that can be used in anywhere. Therefore, This system Will be useful as for doctors to make decision.

Purpose: The influence of dietary composition on blood pressure is an important subject in healthcare. Interactions between antihypertensive drugs and diet (IBADD) is the most important factor in the management of hypertension. It is therefore essential to support healthcare providers' decision making role in active and continuous interaction control in hypertension management. The aim of this study was to implement an ontology-based clinical decision support system (CDSS) for IBADD management (IBADDM). We considered the concepts of antihypertensive drugs and foods, and focused on the interchangeability between the database and the CDSS when providing tailored information. Methods: An ontology-based CDSS for IBADDM was implemented in eight phases: (1) determining the domain and scope of ontology, (2) reviewing existing ontology, (3) extracting and defining the concepts, (4) assigning relationships between concepts, (5) creating a conceptual map with CmapTools, (6) selecting upper ontology, (7) formally representing the ontology with Protege (ver.4.3), (8) implementing an ontology-based CDSS as a JAVA prototype application. Results: We extracted 5,926 concepts, 15 properties, and formally represented them using Protege. An ontology-based CDSS for IBADDM was implemented and the evaluation score was 4.60 out of 5. Conclusion: We endeavored to map functions of a CDSS and implement an ontology-based CDSS for IBADDM.

Background : Currently, ontology research has led the trend of technical development in medical informatics area. For Korean medicine, the reference terminology should be developed to facilitate the ontology research. Objective : This research aimed to design the management system for traditional Korean medical terms. Method :We built the internet-based system in which multi-users work simultaneously by using the relational database system(SQL Server2005) and visual studio 2005. Result : By this system, researchers can collect, refine, and inspect Korean medicine terms efficiently, and the terms can be transcribed into synonym, Korean, Chinese, and simplified Chinese. It enables the terms be input into the system accurately and managed by its classification. Conclusion : We developed the concept groups and its hierarchy system for Korean medicine terms which provides the basis for ontology system.

Objectives: This research presents the design and development of a software architecture using natural language processing tools and the use of an ontology of knowledge as a knowledge base. Methods: The software extracts, manages and represents the knowledge of a text in natural language. A corpus of more than 200 medical domain documents from the general medicine and palliative care areas was validated, demonstrating relevant knowledge elements for physicians. Results: Indicators for precision, recall and F-measure were applied. An ontology was created called the knowledge elements of the medical domain to manipulate patient information, which can be read or accessed from any other software platform. Conclusions: The developed software architecture extracts the medical knowledge of the clinical histories of patients from two different corpora. The architecture was validated using the metrics of information extraction systems.
