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.

This study aims to establish the standards to give the design weight in case when developing equipment designs, by classifying products with similar purposes in accordance with the morphological characteristics and also extracting the typicality. Limiting the sampling group for the extraction of the typicality to a pendant-type and a ceiling buried-type through the preceding case study and consultation with experts, the survey was conducted for majors and relevant workers in six cities, sampling products released in Korea and Japan before May 2016. The 1st survey was about the Morphological classification, and the 2nd times about the extraction of the typicality while the 3rd one was about the classification of the morphological attributes. By drawing the design attributes based on the functional/morphological classification and formative principles, it aimed to establish the base of the future research on the measurement of design weight. The results of this study aim to efficiently establish the roles of design technology in accordance with changes in the lighting fixture market caused by the substitution of light sources, and also to draw the development direction to rapidly cope with the accelerated changes in lighting design types and corporate R&D.

This report is aimed to be used as the basic research resource about the various form expression about the picture books, based upon the analysis whether male and female children are different from their preferences to illustrations and whether the expression form between male and female children are different from the other. The objects of study are one hundred and sixteen's of 6 to 7 years old children (male 58 vs. female 58) who are able to understand the illustration. The two times of response surveys were done with one hand is to interview an individual child and the other hand is to fill out by children. The methods used in this study are composed of the representable, simple, exaggerated, and distorted form of expression in order to draw the detail and precise reactions of male and female children In the case of preference analysis of male and female about the illustration, both male and female prefer the distorted form which express contradictively rather than the real, representable, simple, and exaggerate form of expression or which expresses the distorted and the changed by the binding of different things. In the respect of the responses, the various responses were seen to the simple and the exaggerated form in comparative with the representable form. In the respect of the analysis of language response, the individual response was highly marked to the representable form, and the informational response, the heuristic response, and the imaginative response.

환경질 개선의 편익추정에 사용되는 헤도닉 가격모형에서 제1단계 헤도닉 함수 추정시 그 함수형태에 따라 결과가 편의를 가질 수 있다. 본 논문에서는 13가지의 각기 다른 비선형 및 선형 헤도닉 함수 등을 한국 주택시장에 적용하여 그 적합성을 이론 및 실증적 방법을 병행하여 검증하였다. 그 결과, 고전적으로 종속변수만을 변환시키는 Box-Cox 함수형태나 Box-Cox 변형계수가 사전적으로 0과 1사이에 있음을 가정하는 오목한(concave) 한 함수형태가 기존 연구와는 달리 한국시장에는 적합한 함수형태가 아니라는 결과를 이끌어 냈다. 나아가 서울 주택시장에 가장 적합한 함수형태는 종속 및 독립변수를 각각 다르게 변환시키는 헤도닉 함수형태임을 보여 주었다. 아울러 본 연구는 간접적으로 헤도닉 가격모형 적용시 그 지역의 주택시장 특성에 관한 연구가 선행되어야 함을 시사하고 있다.

Univariate and multivariate analyses of morphometric characters were performed with samples of three subspecies of striped field mice (Apodemus agrarius coreae, A. agrarius pallescens, and A. agrarius chejuensis). It was found that the samples of A. agrarius chejuensis from Jeju-Do were distintc from those of the other two subspecies from the Korean peninsular, whereas subspecies coreae was similar to subspecies pallescens: it is concluded that A. agrarius pallescens is a synonym of A. agrarius coreae. Further analyses will be needed to clearify the subspecific status of A. agrarius chejuensis.

Bridge design is a problem-solving process whose level of design quality strongly depends on how to relate design constraints with feasibile design objectives in conceptual design stage. This paper has focused on how to create bridge shapes using creativity toward better looking bridge appearances in conceptual design stage. The term creativity in this study does not refer to the creation of something from nothing but to the reorganization of existing concepts. Such creativity includes not only enlarging the number of structural forms which is established based on the relationship between form and statics but also combining bridge design with artistic components like an architectural style. Also, this study has investigated the usefulness of graphic statics as a structural analysis tool showing the analysis results visually to generate bridge forms in conceptual design stage. It is expected that the proposed way of generating bridge forms in this study to be used not only for practical purpose but also for educational purpose regarding the aesthetic bridge design serving as a new education paradigm.

자바 프로그램은 클래스의 집합으로 이루어지며 클래스는 필드와 메소드로 구성된다. 필드는 힙 메모리에 저장되므로 필드의 사용 형태는 힙 메모리의 사용 형태에 직접적인 영향을 미친다. 즉 자바 힙 메모리의 사용을 분석하기 위해서는 필드의 사용 형태를 분석해야 한다는 것이다. 본 논문에서는 전형적 자바 프로그램에서 필드가 어떻게 사용되어지는지를 정성적으로 분석하고 실험을 통해 확인하였다. 본 연구의 결과는 자바가상기계의 힙 메모리 구조 개발에 도움을 줄 것이며, 나아가 효율적인 자바가상기계의 개발을 가능하게 할 것으로 기대된다.

지금까지 국내에서 개발된 반사판 설계툴은 2차원적인 형태를 고려하여 만들어졌다. 그러나 가로등이나 투광기 같은 형태의 반사판을 설계할 때에는 2차원이 아닌 3차원적인 형태를 고려하여 설계되어져야하고, 반사광이 램프에 흡수되는 것을 고려하여 설계해야 한다. 본 논문에서는 3차원 형태의 반사판을 여러 방향으로 잘라서 먼저 2차원적으로 설계하고, 이를 연결하여 3차원 형태의 반사판을 만드는 방법을 제시하고자 한다.
