The development of web-aware knowledge discovery system has received a great deal of attention in recent years. It plays a key-enabling role for competitive businesses in the E-commerce era. One of the challenges in developing web-aware knowledge discovery systems is to integrate and coordinate and coordinate existing standalone or legacy knowledge discovery applications in a seamless manner, so that cost-effective systems can be developed without the need of costly proprietary products. In this paper, we present an approach for developing a framework of web-aware interoperable knowledge discovery system to achieve this purpose. This approach applies RMI and high-level code wrapper of Java distributed object computing to address the issues of interoperability in heterogeneous environments, which includes programming language, platform, and visual object model. The effectiveness of the proposed framework is demonstrated through the integration and extension of the two well-known standalone knowledge discovery tools, SOM_PAK and Nenet. It confirms that a variety of interoperable knowledge discovery systems can be constructed efficiently on the basis of the framework to meet various requirements of knowledge discovery tasks.

최근 생물정보 기술이 암 진단의 새로운 방법으로 관심을 모으고 있다. 다양한 기계학습 기법이 적용되어 우수한 결과를 얻고 있지만 의학 분야에서는 정확률이 높은 분류기뿐만 아니라 획득된 분류규칙을 사람이 분석하고 이해할 수 있어야 한다. 생물정보 기술에서 많이 이용되는 유전자 발현 데이터는 데이타 내에 수천 내지 수만의 변수가 존재하며, 직접 이들 사이의 복잡한 관계를 표현하고 이해하는 것은 매우 어렵다. 본 논문에서는 이러한 어려움을 극복하기 위해 유전자 발현 데이타에서 분류에 유용한 특징들을 추출하고 산술 연산자 기반 유전자 프로그래밍으로 암 분류규칙을 생성하는 방법을 제안한다. 림프종 유전자 발현 데이타에 대하여 실험하여 96.6%의 인식률을 얻었으며, 획득된 분류 규칙을 분석하여 다양한 지식을 발견할 수 있었다.

지능 로봇은 복잡하고 동적인 환경 내에서 상황의 변화에 적절히 적응하여 사용자에게 다양한 서비스를 제공하는 지능 시스템이다. 따라서 로봇은 행위를 수행하는 동안 지속적으로 상황의 변화를 감지하여 변화에 적절히 반응해야 하며 주어진 상황에 대해 최선의 행위를 결정하여 수행할 수 있어야 한다. 또한 때때로 임의의 행동을 결정하여 보다 지능적인 행위를 수행할 수 있어야 한다. 본 논문에서는 이러한 지능 로봇의 복잡한 행위를 효과적으로 정의하고 구현하기 위해 Structured Circuit Semantics(SCS)에 기초를 둔 프로그래밍 언어(Structured Programming for Reactive Intelligent Tasks, SPRIT)와 SPRIT으로 작성된 프로그램을 다양한 로봇 환경에서 실행하고 검증하기 위한 작업 실행기(Task Executor)를 제시한다.

Purpose: This study was done to develop and implement the Nursing KMS (knowledge management system) in order to improve knowledge sharing and creation among clinical nurses in outpatient departments. Methods: This study was a methodological research using the 'System Development Life Cycle': consisting of planning, analyzing, design, implementation, and evaluation. Quality Function Deployment (QFD) was applied to establish nurse requirements and to identify important design requirements. Participants were 32 nurses and for evaluation data were collected pre and post intervention at K Hospital in Seoul, a tertiary hospital with over 1,000 beds. Results: The Nursing KMS was built using a Linux-based operating system, Oracle DBMS, and Java 1.6 web programming tools. The system was implemented as a sub-system of the hospital information system. There was statistically significant differences in the sharing of knowledge but creating of knowledge was no statistically meaningful difference observed. In terms of satisfaction with the system, system efficiency ranked first followed by system convenience, information suitability and information usefulness. Conclusion: The results indicate that the use of Nursing KMS increases nurses' knowledge sharing and can contribute to increased quality of nursing knowledge and provide more opportunities for nurses to gain expertise from knowledge shared among nurses.

A design system for mechanical components is being developed using an Object-Oriented Programming language Smalltalk to allow mechanical designers to use the experience of expert designers. The system is organized in such a manner that the expert knowledge stored in it could be easily retrieved by the junior designer. The experience and the knowledge of the expert are placed in the databases. Multiple design models, in this system, can be processed simultaneously, because the expert knowledge is broken down into elements which can be used by different design models. In this way the system proves more flexible and extendable. In this paper, the philosophy of the system and the databases involved in the system will be addressed.

Web2.0 refers to a new service models based by a community oriented philosophy. This creates new opportunities for technology providers and service. The agricultural technology information service in the base of open source technology provide opportunities for increased distribution and visibility to farmer and general user. We would like to find out vest service models and platform that will find new ways of agriculture technology information service. This study suggests that these new agriculture information service strategy in new paradigm of web 2.0. should be revised and adapted to Open API and new applied strategy in agriculture should be developed considering the impact of web 2.0.

구조물 모니터링 시스템의 전산환경을 구성하기 위해 필요한 지식 및 정보를 파악하고 이를 지식기반화하는 방법을 제시하였다. 전산환경의 구축을 위한 정보로는 센서 및 하드웨어, 신호처리, 그리고 손상발견/평가를 위한 지식등이 필요한데, 이들은 모두 다른 형태의 지식이므로, -즉 수학연산, 서술적 지식, 수치모델등- 어느 특정의 모델링 기법 단독으로는 이들을 효과적으로 수용하기가 매우 어렵다. 이를 해결하기 위하여 객체지향적 모델링기법과 논리언어를 혼합사용하는 방법 (Hybrid Modeling Paradigm)이 제시되었고, 이의 타당성 및 효율성 검증을 위해 모델구조물을 이용한 예제를 수행하였다.

Expert system is a practical application part of the artificial intelligence and can be generally described as a computer-based system designed to simulate the knowledge and reasoning of a human expert, and to make that knowledge conveniently available to other people in a useful way. Expert systems consist of three major components, knowledge base, inference engine and user interface. In this paper, it is aimed to construct a prototype system to design the horizontal-typed pressure vessel. To do this, a representative artificial programming language, Turbo Prolog, was employed, and the knowledge representation was mainly done by the production rule such as "If(condition), than (action)" style and by the predicate logic. In the developed system, it was quite easy to represent the knowledge of "If(condition), then (action)"style and by the predicate logic. In the developed system, it was quite easy to represent the knowledge of "If(condition). then(action)" style and the various table-like data. It was also effective to represent the graphics. Though this expert system is by now small and incomplete, it is possible to expand it to a larger and refined system later.rger and refined system later.

Using computer technology in teaching school mathematics creates new instructional environments. The emphases on the use of computer technology in the classrooms and in particular the use of computer-based exploration as a context of mathematics instruction have been reflected in the recommendation of the NCTM (Curriculum and Evaluation Standards for School Mathematics, 1989). Although the power of using computer technology in the exploration of mathematical problems has been recognized and stressed by many educators, we do not have many research studies on mathematics in computer-based explorations. Especially research has failed to clarify how computer technology can contribute to the construction of procedural and conceptual knowledge of mathematics. Up to now most researches on procedural and conceptual knowledge in computer environments have only focused on classifying programming languages which program language has more random access and rich interrelationship characteristic in relation to conceptual knowledge in humans, and which computer language has more characteristic flavor of procedural knowledge. How computer-based explorations affect the knowledge construction of mathematics, therefore, emerges as an issue of research on teacher education program for theoretical framework. This situation leads to do research on the effectiveness of using computer explorations in pre-service teacher education in terms of procedural and conceptual knowledge construction.

프로그래밍 언어 학습이 논리적 사고력에 미치는 영향에 대한 선행 연구는 부족한 실정이며, 각 연구 결과마다 연구 대상, 방법과 학습 주제 등에 따라 논리 향상 정도와 영역이 다르므로, 일반화 과정에 어려움이 있다. 또한 논리적 사고력의 향상이 학습자의 인지 발달에 의한 것인지 프로그래밍 언어 학습에 의한 것인지 분명하지 않아 프로그래밍 언어 학습의 필요성이 증명되었다고 할 수 없다. 본 연구에서는 초등 6학년생들에게 교육용 프로그래밍 언어 학습을 7차시 동안 실시한 후, 메타인지 수준별로 논리적 사고력에 미치는 영향을 조사하고, 컴퓨터 활용 교육의 효과와 비교하였다. 실험 결과에 따르면, 두리틀과 로고, 그리고 파워포인트 학습 집단 모두에서, 상위 수준의 메타인지를 지닌 학생들은 논리적 사고력에 유의미한 신장 효과를 나타낸 반면, 하위 수준의 학생들은 두리틀과 로고 학습 후에만 유의미한 논리적 사고력의 신장을 나타냈다. 그러나 메타인지 수준에 상관 없이 세 학습 집단 간에 논리적 사고력 향상 정도의 유의미한 차이는 없었다.
