Among many design processes such as learning, storing, retrieving and applying, the process that learns design knowledge is very important for producing creative results that solve design purposes in design computations. The computer should have the ability similar to human in learning design knowledge. It should recognize not only physical properties but also high level design knowledge constructed from the first level physical properties. The high level design knowledge are recognised in terms of isometric translation relationships. This paper explains properties of isometric translation and methods how the computer can recognize high level shape design knowledge using shape pattern representation.

인터넷 등 각종 미디어의 발달은 정보에 대한 접근과 취득을 용이하게 만들었고 교육내용의 유용한 전달수단으로 자리 잡았다. 그러나 인터넷의 수많은 정보 중에서 단순한 정보의 취득만으로는 비구조적이고 복잡 다양한 여러 문제를 해결하는데 큰 효과를 발휘하지 못하므로 정보를 가공하여 도출되는 결과물인 지식을 취득하고 활용하여 문제를 해결하는 방안을 제시하였다. 인터넷의 엄청나 정보량은 어떤 정보가 학습자에게 필요한지 파악하기 어려우며 또, 원하는 정보를 적시에 손쉽게 취득하여 학습자가 원하는 지식으로 조합할 수 있는 방법에 익숙치 못하다. 지식검색 서비스는 간단한 키워드의 사용만으로 다양한 지식을 정보의 형태가 아니라 지식의 형태로 제공하기 때문에 빠르고 간편하게 문제를 해결하는 방법으로 지식검색 서비스 활용도는 매우 커지고 있다. 그러나 새로운 지식습득 방법으로 제시되는 지식검색 서비스가 과연 문제중심학습 등에서 문제를 해결할 수 있을 정도로 제공되는 지식이 정확성을 가지고 있는지, 다양한 범위를 가지는지, 손쉽게 사용할 수 있는지 등을 검증할 필요가 있다. 따라서 본 연구에서는 기존의 전통적인 검색방법을 이용한 지식습득과 지식검색 서비스를 이용한 지식의 습득에서 오는 차이를 분석하여 문제중심학습 등에 적용 가능한 현실적인 지식습득 방법과 개선책을 제시하고자 한다.

This study investigates how learners extract their implicit knowledge into explicit form of the knowledge. The process of implicit-explicit transfer is known to help learners to reconstruct and refine their knowledge which was constructed before in some ways. Also we investigate which types of explicit form are more effective when it is delivered to other learners. In a classroom-based learning environment, students take educational content that is delivered by instructor and go through the process in which they try to fit the content into their cognitive structure by reconstructing the knowledge into their cognitive model. When they try to deliver their own cognitive model for the knowledge to other learners, they have to transform it into explicit form, and through the process, they reconstruct and refine the cognitive model of the knowledge, and find effective and appropriate way to express it. In this research, we experimented the process on a group of 77 college students and analyzed the results. We also did peer evaluated experiments to see which types of explicit format and factors are more effective than others. The results indicate that the types of explicit form of implicit knowledge play an important role in effectiveness of learning.

A window presentation style, either tiled window or single page design, determines the spatial arrangement of information in a modern computer-based instructional design. This study investigates the interaction between spatial ability and window presentation style in terms of student's achievement of cognitive knowledge through Web-based instruction. Seventy-one students from the Falk School in Pennsylvania were pre-tested to determine their level of spatial ability, then randomly divided into two treatment groups in order to study a Web-based instructional unit on flowering plants. The Web-based instructional package was organized with either tiled window presentation or single page presentation. A posttest measured participants'acquisition of the instructional content. Posttest and spatial ability test scores were analyzed using multi-variate linear regression for the full sample (n=71) and three sub-samples: (a) 4th and 5th grade students only, (b) female students only, and (c) 4th and 5th grade female students only. The goals of the data analysis included the examination of (i) the correlation between spatial ability and posttest scores; (ii) the correlation between window presentation style and posttest score; and (iii) the interaction between spatial ability (aptitude) and presentation style (treatment).The data from all four sample groups showed a significant relationship between spatial ability and achievement of cognitive knowledge at the 1% level of significance. The aptitude-treatment interaction between spatial ability and style of window presentation was not significant in the full sample, but was significant in the sub-samples either at the 10% or 5% level. In neither the full sample nor any sub-sample data did window presentation style have an impact on average posttest score. In all analyses, the higher the level of spatial ability, the higher the posttest score. The sub-samples revealed that students with low spatial ability performed better with the tiled window presentation, while those with high spatial ability did better with the single page presentation. Neither window presentation style was shown to better foster learning by children of all levels of spatial ability.

Art historians and critics have defined the style as common features appeared in a class of objects. Abstract common features from a set of objects have been used as a bench mark for date and location of original works. Commonalities in shapes are identified by relationships as well as physical properties from shape descriptions. This paper will focus on how the computer and human can recognize common shape properties from a class of shape objects to learn design knowledge. Shape representation using schema theory has been explored and possible inductive generalization from shape descriptions has been investigated. Also learned shape knowledge can be used. for new design process as design concept. Several design process such as parametric design, replacement design, analogy design etc. are used for these design processes. Works of Mario Botta and Louis Kahn are analyzed for explicitly clarifying the process from conceptual ideas to final designs. In this paper, theories of computer science, artificial intelligence, cognitive science and linguistics are employed as important bases.

In comparison with the acquirement of knowledge by expression of symbol or numerical formula, the experience based knowledge acquirement give stable and clear understanding of information to a learner. Various educational systems based on computer such as virtual reality, intelligent learning system, visualization of concept, simulation-based system, and microworld have so far been developed. In this paper, a method of two dimensional visualization of a physical law by simulation has been suggested to educate a learner. Especially, learning the law of gravity by simulation based educational method gives a learner indirect experience that enhance the efficiency of knowledge acquirement clearly. The visualization methods of a real-time physical law and a virtual anomalies' physical law by simulation are proposed in this paper to deliver information or knowledge clearly. Then we show that a learner can acquire some knowledge effectively by the proposed method.

오늘날 딥러닝은 교육을 포함한 다양한 분야에서 세상의 패러다임을 바꿀만큼 발전하고 있다. 그러나 딥러닝 모델이 어떤 지식을 습득하였는지 파악하기 어려워 딥러닝 시스템을 무조건적으로 신뢰할 수 없다는 것이 문제로 남아있다. 이 문제를 해결하기 위해 기존에 딥러닝이 학습한 결과를 If-then과 같은 형식의 규칙으로 추출하는 방법이 제안되었지만, 이러한 규칙은 사람이 이해하기에는 직관적이지 못하다는 단점을 가지고 있다. 본 논문에서는 이러한 문제를 해결하고자 딥러닝 모델이 습득한 지식을 규칙 형태로 추출하고 이를 시각화하여, 사람이 직관적으로 이해할 수 있는 형태로 표현하는 방법을 제시한다.

21세기 정보화 사회는 방대한 양의 정보가 다양한 형태로, 언제, 어디서나 손쉽게 구해질 수 있으며, 인간의 지적 기능을 정보통신기술이 대신할 수 있게 되어 우리의 경제 행위, 사회 생활, 가치관도 크게 변화될 것으로 전망된다. 그 중에서도 가장 두드러진 변화는 지식의습득보다는 지식을 이용하여 새로운 지식을 창조할 수 있는 능력이 중요한 가치로 인식되고 있다는 점이다. 정보화 사회에 부응하여 새로운 과학기술, 새로운 지식 그리고 새로운 문화의 창조력을 갖는 국민의 지적 능력을 개발하고, 교육의 틀을 바로 세우기 위한 교육개혁이 추진되고 있다.(중략)

This study investigated the effects of an Augmented Reality(AR) implemented book on flow of reading, interest in history, and acquisition of history knowledge. Perceptions of AR infused books were investigated as well. Researchers provided a history book implementing AR and the same book without any AR content respectively to an experiment group(n=15) and a control group(n=15) composed of $3^{rd}$ and $4^{th}$ grade elementary school children. Results indicate that AR implemented reading had a positive effect on the flow of reading and interest in history, but not on acquisition of history knowledge. Also, AR-based contents were attractive to learners due to its amusing characters, sound, realistic visual motions, and vivid three-dimensional effects. Lastly, students preferred amusing interesting characters, lengthier animations and subtitles, and AR that could be seen without holding smart devices for a long while.

이 연구는 환자의 치위생학적 지식 및 실천 정도가 구강건강과 관련된 삶의 질에 미치는 영향을 측정하고자 평가도구중 하나인 구강건강 영향지수(OHIP)를 사용하여 평가하였다. 그 결과 예방적인 지식이나 일상에서 매일 사용하는 구강용품지식 및 사용방법 지식이 높아야 주관적으로 느끼는 삶의 질이 높게 나타났다. 그리고 진료 형태별 지식과 같이 경험으로 습득한 지식은 높을수록 주관적으로 느끼는 삶의질이 낮게 나타났다. 반면 심미치료중의 하나인 미백치료지식은 높을수록 주관적으로 느끼는 삶의 질이 높게 나타났다. 즉 예방적이고 심미적인 지식이 구강건강영향지수에 영향을 미치는 것으로 분석된다.
