The constant evolution of society, culture and scientific technology, coupled with changes in life style and behavioral patterns, has led mankind to peroeive diverse needs for space. Particularly, the rapid structural change in the field of marketing has entailed changes in techinques for construction and presentation of space for an improved marketing environment. To satisfy such new, diverse needs for space, interior designers will have to redefine the "mankind and environmen( concept and examine their design methodology anew. The question of how to design available space for a certain purpose will remain a daunting task for designers in the future, as it has been in the past. In the pursuit of convenience and conformity to mankind's surroundings, every nation has, in common with other nations, basic design elements, design skills and other factors. In designing camercial space in a particular region, it is essential, however, to have a proper understanding of the social economic and cultural context indigenous to that region, as well as the impact on environmental and ecological change and marketing strategy. This study discusses design metholdology for the comming camercial space on the basis of the space concept and current status in Korea, with major emphasis on Korea's regional characteristics.

An experimental feasibility study of the E3.9 engine with CP3.3 and EDC7C was conducted to understand the initial performance and the possibility for EURO-III regulation. ID cycle simulation for concept study was conducted using the BOOST. Also, some basic investigations through such various parameters as injection timing and rail pressure have been carried out to find the feasibility on EURO-III ESC mode. Based on the results, the feasibility of the E3.9 engine for EURO-III characteristics such as performance, emissions, and fuel economy was demonstrated.

The purpose of this study was to introduce the concept of social capital to the studies of human ecology in Korea. Social capital theory provides a framework for analyzing well being of families because the concept of social capital can be understood as an important family resource, including social networks, social supports, and family structure. The utilization of the social capital theory, considering both positive and negative effects on equality, in the studies of human ecology is expected to contribute to the social understanding of the characteristics of households as a system that are related with environments, and provide a basic theoretical framework for discussing family structure, human capital development, poverty, and healthy families.

Fibro-osseous lesions are composed of connective tissue and varying amount of mineralized substances, which may be bony or cementum-like structures. It is necessary for oral radiologist to differentiate due to the tendency of these fibro-osseous lesions to show similar histopathologic appearances, while the management of each lesion is different. However we often encounter a little difficulty in judgement because there are some overlaps between concept of each lesions. So recently I suggest, we face a need to review basic concept and classification of several fibro-osseous jaw lesions. In this article, several fibre-osseous lesions, such as fibrous dysplasia, cemento-ossifying fibroma and cemento-osseous dysplasia, will be discussed basing on the review of literature. particular emphasis will be made on the nomenclature revision of WHO's classification in 1992.

In early 1970s, open education was introduced with drastically changing educational concept. Since then, open education has brought about new concept and variations in curriculum, schools have adopted open education since mid 1980s. Open education which has advanced in foreign countries, how-ever, do not fit to the Korean educational situation without some modification in educational facilities. This education in Korea faced and making some suggestions on educational facilities for the effective open ducation in Korea. After briefly reviewing the conceprs of open education. I introduced educational facilities for open education regarded as basic in advanced countries, then I analyzed through questionaire current status of educational facilities of 23 Korean schools which have adopted open education. Finally I made some suggestions to improve educational facilities for effective open education of Korea.

The purpose of this study was to analyze basic conditions for the demand estimation erection of lifetime sports facilities. This is described the whole concept of lifetime sports(sport for all) for helping the understanding of its concept correctly. Firstly, second chapter was examined the significance, function and role of lifetime sports in modern society. Secondly, third and forth chapter was examined demand and participation of lifetime sports activities for demand estimation of lifetime sports facilities. Participation rate is on the rise by the increase in income and leisure time to some extent, but after that it stops rising. In other words, the same participation rate persists without additional increase in participation by the changes in time deepening and in the patterns of demand for lifetime sports activities.

The purpose of this paper is to develop an integrated environment system for finite element structural analysis using OOA(Object-Oriented Analysis) and OOD(Object-Oriented Design), with may reduce inconveniencies in use such as file input of macro command and improve lacks of graphic presentation in the established finite element analysis program. This paper is attempted to suggest an easy approach to object-oriented concept and convenient programming. Two languages are used together in this paper instead of single C++ language for the development of object-oriented program. : Visual Basic with CDK(Custom Development Kit), and Borland C++ with OWL(Object Windows Library).

A general concept on the definition of the second law efficiencies of thermodynamic cycles is introduced. The efficiency is defined to be proportional to the entropy generation divided by the maximum possible entropy generation. This way of definition of the cycle efficiency is clear and concise and, moreover, follows faithfully the concept of the second law of thermodynamics. This definition is applied to heat engine, refrigerator and heat pump. The second law efficiencies of heat engine and refrigeration cycles are derived, which are the same as the existing ones, respectively. The second law efficiency of heat pump, however, finds to be different from the existing one. Discussion is given about the difference and its cause.

We introduce the concept of fuzzy $r$-minimal ${\beta}$-open set on a fuzzy minimal space and basic some properties. We also introduce the concept of fuzzy $r-M$ ${\beta}$-continuous mapping which is a generalization of fuzzy $r-M$ continuous mapping and fuzzy $r-M$ semicontinuous mapping, and investigate characterization for the continuity.

The purpose of this study was the identifying differences between physicists' expectations and teachers' representations about the primary physics concepts in elementary schools. For this, the material subjects analyzed were the 7th curriculum, the textbooks of elementary school and the texts using at the department of physics in many universities. The primary physics concepts extracted from the texts were to be fundamental and basic. Also, they were restricted to the domain of dynamics. And besides, the human subjects were physicists, professors and students majoring physics of the graduate school, researchers of institutes or laboratories and elementary school teachers. At the result of this study showed the scholars and teachers have the different opinions.
