위성의 수와 복잡도가 증가함에 따라서 다양한 고장이 생기는 경우를 예측하고 고장이 발생한 경우 이를 감지하여 신속히 감지하여 처리하는 노력의 필요성이 증가하게 된다. 현재는 위성 관제소의 전문요원들이 이러한 작업을 수행하고 있지만, 많은 부분이 일상적인 작업이므로 이러한 진단 작업을 자동화할 필요성이 있다. 즉, 일상적인 작업은 전문가시스템이 수행하고, 보다 복잡하고 고차원적인 문제는 전문요원이 해결하는 방식이 바람직하다. 이 논문에서는 이러한 노력의 일환으로 인공지능의 사례기반 방식을 도입한 위성 고장진단 전문가시스템을 구축하기 위한 방법론과 이에 따른 프로토타입 시스템을 설계하고 구현하였다. 사례기반 시스템은 과거의 사례를 기억하고 있는 사례베이스를 구축하고 고장의 증상이 발생한 경우에 이러한 사례베이스로부터 가장 근사한 경우를 인덱스하여 처리하는 기능을 가지고 있다. 이 논문은 이러한 기능을 가지는 사례기반 시스템의 구조와 활용방안에 대해서 서술하고자 한다.

This research reviewed literatures on proof in mathematics education. Several views of proof can be classified (and identified) such as psychological approach (Platonism, empiricism), structural approach (logicism, formalism, intuitionism) and social approach (ontology, axiomatic systems). All these views of proof are valuable in mathematics education society. The concept of proof can be found in the form of analytic knowledge not of constructive knowledge. Human beings developed their knowledge in the sequence of constructive knowledge to analytic knowledge. Therefore, in mathematics education, the curriculum of mathematics should involve the process of cognitive knowledge development.

In this paper we describe an approach to coordinating the motion of a human with a mobile robot moving in a populated, continuously changing. natural environment. Our test application is a wheelchair accompanying a person through the concourse of a railway station moving side by side with the person. Our approach is based on a method for motion planning amongst moving obstacles known as Velocity Obstacle approach. We extend this method by a method for tracking a virtual target which allows us to vary the robot's heading and velocity with the locomotion of the accompanied person and the state of the surrounding environment.

Since the Human Genome Project(HGP) has begun in the mid 1980s, the sequencing of the human genome has been finally completed in 2001. The knowledge developed from the HGP has revolutionized how health care professionals think about patient care, mandating a new paradigm of patient care in totally inconceivable ways from the past. For instance, the patients at risk for disease can be identified early enough for intervention; the medicine can be tailored for individual patients based on their own genetic information ; the gene therapy could be a common procedure in the near future. The advancement in genetics, therefore, requires the shift of paradigm not only in nursing education, practice, but also in nursing research. It is attempted, in this article to introduce briefly the basic knowledge of genetics, the pharmacogenomics, and the overview of national genetic research initiated and organized by the Center for Functional Analysis of Human Genome in Korea. The current state of nursing genetic knowledge and its implications on nursing education, practice, and research has examined. Furthermore, the visions and the opportunities for nursing science and practice to participate in this genetic revolution were also explored.

지식기반사회로 진전됨에 따라 경제성장의 원동력으로서 인적자본(human capital)의 중요성이 부각되면서 인적자본의 외부효과에 대한 관심이 매우 높아지고 있다. 본 연구는 근로자의 임금에 영향을 주는 결정요인을 개인 수준, 기업 수준, 지역 수준별로 위계선형모형을 구축하여 인적자본의 외부효과를 분석하는데 목적을 두었다. 또한 지식확산의 강도가 학력그룹별로 다를 것이라는 가설 하에서 고학력자 그룹과 저학력자 그룹의 인적자본의 외부효과를 비교하였다. 3단계 위계선형모형 추정 결과 지역의 평균 교육수준이 1년 증가할 때 근로자의 평균 임금이 4.4% 상승하는 것으로 나타나, 인적자본의 외부효과가 있음을 말해준다. 이러한 인적자본의 외부효과는 학력수준 집단별로 차이를 보이는 것으로 나타났다. 즉, 학력수준을 고졸 이하와 전문 일반대 졸업, 그리고 석 박사 졸업으로 그룹화하여 인적자본의 외부효과를 산출한 결과 각각 3.0%, 4.7%, 11.8%로 나타나, 고학력으로 갈수록 인적자본의 외부효과가 더 크게 나타나고 있다. 이와 같이 학력 수준별 인적자본의 외부효과가 상이하게 나타나며, 고학력으로 갈수록 외부효과가 더 커지고 있다는 점을 고려해 볼 때 지방의 경쟁력을 살리기 위해서는 인적자본의 외부효과를 높일 수 있는 방안을 적극적으로 모색하여야 할 것이다.

Development of human-system interfaces (HSI) supporting the interaction between human and automation-based systems, particularly safety-critical sociotechnial systems, entails a wide range of design and evaluation problems. To help HSI designers deal with these problems, many methodologies from traditional human-computer interaction, software engineering, and systems engineering have been applied; however, they have been proved inadequate to develop cognitively well engineered HSI. This paper takes a viewpoint that HSI development is itself a cognitive process consisting of various decision making and problem solving activities and then proposes a design requirements-driven process for developing HSI. High-level design problems and their corresponding design requirements for visual information display are explained to clarify the concept of design requirements. Lastly, conceptual design of software system to support the requirements-driven process and designers' knowledge management is described.

The purpose of this study was to investigate nutrition knowledge, dietary attitude and a food habits of middle school students. The study was carried out through questionnaire. The subjects were 431 middle school students (boys 298, girls 133) in Chonbuk area. In nutrition knowledge, there were no significant differences in total scores between boys and girls. However, the girls showed higher score in knowledge of weight control than boys did (p<0.05). In dietary attitude, there were significant differences in attitude of 'balanced meal (p<0.05)', 'sufficient protein intake (p<0.01)', 'food diversity (p<0.001)' and 'overeating(p<0.00)' between boys and girls. The boys showed better dietary attitudes than the girls did. In food habits, there were significant differences in the rate of skipping breakfast (p<0.05), the rates of skipping dinner (p<0.001), the frequency of snacks (p<0.05), the type of snacks (p<0.05) between boys and girls. The girls showed higher rates of skipping a meal and frequency of snacks than the boys did. It suggests that gender should be considered for an effective and practical nutrition education for middle school students to improve dietary attitudes and food habits.

Most of expert systems use the text-oriented knowledge bases. However, knowledge management using the knowledge bases is considered as a huge burden to the knowledge workers because it includes some troublesome works. It includes chasing and/or checking activities on Consistency, Redundancy, Circulation, and Refinement of the knowledge. In those cases, we consider that they could reduce the burdens by using relational database management systems-based knowledge management infrastructure and convert the knowledge into one of easy forms human can understand. Furthermore they could concentrate on the knowledge itself with the support of the systems. To meet the expectations, in this study, we have tried to develop a general-purposed knowledge conversion tool for expert systems. Especially, this study is focused on the knowledge conversions among text-oriented knowledge base, relational database knowledge base, and decision tree.

As a work analysis technique, Work Domain Analysis (WDA) aims to identify the design knowledge structure of a work domain that human operators interact with through human-system interfaces. Abstraction hierarchy (AH) is a multi-level, hierarchical knowledge representation framework for modeling the functional structure of any kinds of systems. Thus, WDA based on AH aims to identify the functional knowledge structure of a work domain. AH has been used in a range of work domains and problems to model their functional knowledge structure and has proven its generality and usefulness. However, many of researchers and system designers have reported that it is never easy to understand the concepts underlying AH and use it effectively for WDA. This would be because WDA is a form of work analysis that is different from other types of work analysis techniques such as task analysis and AH has several unique characteristics that are differentiated from other types of function analysis techniques used in systems engineering. With this issue in mind, this paper introduces the concepts of WDA based on AH and offers a comprehensive list of references. Next, this paper proposes a set of principles for effectively applying AH for work domain analysis, which are developed based on the author's experiences, consultation with experts, and literature reviews.
