  • This paper briefly summarizes the basic concepts and main characteristics of seismic design of New Zealand Standards(NZS) with regard to reinforced concrete(RC) structures. NZS used the concept of the capacity design and the limit state design to satisfy the requirements of serviceability and safety. Plastic mechanisms and details with respect to the limit state of safety are briefly presented in this paper. The understanding of this advanced seismic design concept will enable us to implement the basic theory of capacity design and contribute to the development of Korean seismic code in new generation,

  • This paper is to refine the concept of utilizing natural energy, and to introduce new technologies of building energy control. For the global environment protection, it is essential to turn attention to latent capacity of natural renewable energy. Especially the concept of 'Environmental Architecture' is very important from this viewpoint. This paper reviews many of new technologies for environmental architecture developed recently : TIM, high effective solar radiation control strategy of glazing, new passive cooling and heating system etc. The design application of the technology has been introduced.

  • Many tools in classical type for the production management have been used in industrial cells. In spite of their powerful logic and historical success, many appliers could not take but a little effectiveness in current economic conditions. The major reason is that the chronical production control methods are too narrow in its applicability to cover the problems occurred under such a high-speed changes. Therefore we need to develop the new concept of production management for the higher adaptability and outcome which can support vitablities to enterprises in severe condition. The essential points in changing the viewpoint of new production management concepts are valuable to the group of new management.

  • In this paper, the new approach and technique are introduced and derived from the original Lyapunov direct method which is used to decide the stability of system conveniently. This proposed technique modifies the formal concepts of the sufficient conditions of Lyapunov stability and is able to generate the methods for the robust design of control systems. Also, it applies to the dynamic systems with bounded perturbations and the results of the computer program using the new concept are compared with those of previous research papers and conventional Lyapunov direct method. It is possible to recognize the practical improvements of the estimation of robustness bounds of the systems.

  • This paper presents the new concept in ac power theory with non-sinusoidal waveform. It will be shown that there is discrepancy in the definition of active and complex power in the time and frequency domains when the conventional power theory is considered It will also be shown that the new power theory consistently defines the power quantifies in the time domains.

  • Reduced life-cycle and scale of electronic products make the conventional automated manufacturing system difficult to keep on competitiveness in these days. Reduced life-cycle requires an agile adaptation of manufacturing to new products and reduced scale requires enhanced precision as well as high speed. In this research, We propose a new concept called as "One-Cell Minifactory" in which various processes are combined to produce final modules or products and human interaction can be combined easily. We hope the proposed concept can guide new developments of automated manufacturing in electronics, optics and bio-engineering.

  • Based on the creative education theory, the study of the symmetric coordinated use of both hands is the application of both the quality education ideal and the understanding principles of the creative education to the training of using hands. In the light of relevant concepts of the 'Domain' theory and the expertise of both the Chinese and foreign specialists in this field, this article discusses the relation between the tapping of mental creativity, scientific use of hands and the animation of the right hemisphere of the brain with the aim of constructing a new concept of the symmetric coordinated use of both hands.

  • This study presents a new design method of courses and programs for interdisciplinary or customized education in university organizations. The concept of modular design in manufacturing industry is employed for the development of new courses and programs design in university education. Diverse customization methods in service processes or service delivery channels in education are excluded in this study to focus on the research purposes. The results of this study can contribute to the development of a new education system for customized or interdisciplinary education in universities.

  • In this study, a new teaching model was developed using concept maps and applied to the Earth Science I unit on diastrophism. We analyzed the effects of this model on students' scholastic achievement, ability to construct concept maps, and attitudes towards concept map lessons, in comparison to traditional teaching methods. The data was sampled from 128 second-year male high school students in Gyunggido, Korea. Although the results are not statistically significant, the new teaching model seems to have contributed to an increase in scholastic achievement as opposed to the traditional teaching models. We also found that the students to whom the new teaching model was applied showed both significant and positive effects in terms of scholastic achievement, the ability to construct a concept map, and changes in attitudes towards concept map lessons.

  • In this thesis was conducted to propose a method for efficient information retrieval using concept lattices. Since this thesis designed a new system based on ordinary concept lattices, it has the same approach method as ontology, but this thesis proposes new concept lattices to be used by establishing collaborative relations between objects and concepts that users are likely to search information more efficiently. The system suggested by this thesis can be summarized as below. Firstly, this system leads to a collaborative search by using Three kinds of concepts, such as keyword concept lattices, which focus on input key words, expert concept lattices recommended by experts and theme concept lattices, and based on these 3 concept lattices, it will help users search information they want more efficiently. Besides, as the expert concept and the keyword concept become combined, further providing users with the frequency of keyword and the frequency of category, this system can function to recommend key words related to search words entered by users. Another function of this system is to inform users of key words and categories used in users' interested themes by using the theme concept lattices. Secondly, when there is not keyword entered by a user, it is possible for users to achieve the goal of search through the secondary search when this system provides them with key words related to the input keyword. Thirdly, since most of the information is managed while being dispersed, such dispersed and managed information not only has different expression methods but changes as time goes. Accordingly, By using XMDR for efficient data access and integration of distributed information, this thesis proposes a new technique and retrieval system to integrate dispersed data.
