The purpose of this study was to determine the effects of self-help management program which strengthens self-efficacy for post stroke elders who attend day care center in Chongju. One group pretest-posttest design was used, and the subjects were 7 post stroke elders with hemiparesis. The self-help management program consisted of 5 sessions and each session included group education on stroke, ROM exercise, recreation and self-care strategies. Those strategies for encouraging and reinforcing self-efficacy provided verbal persuasion, performance accomplishment and vicarious experience. All subjects were questioned before and after the program about ADLs, IADLs, self-efficacy, self-care behavior and depression. The analysis of data revealed that the program was effective to increase the IADLs, self-efficacy and self-care behavior. However, there was no significant difference between pre and post ADLs and depression. The results indicated that this program may be adopted to improve the physical and psychological function of post stroke elderly patients in community settings.

본 논문에서는 트랜스포머의 자가공진 특성에 대하여 분석하였으며, 부유용량과 권선량, 권선비에 따른 변화관계를 수식으로 정리하였다. 일반적으로 트랜스포머에서의 부유용량은 제작과 관련하여 불요인자로 간주되나, 모든 트랜스포머에서 내재하는 특성을 갖는다. 특히 고역의 구동 주파수에서는 해당 특성이 확연하게 나타남은 주지의 사실이며, 자기적 요소와 결합하여 특정주파수에서 공진형상을 유발한다. 출력이득 값이 높아야 하는 소형 고전압기기, 특히 의료용 응용전기기의 경우 트랜스포머의 자가공진 특성을 이용하면 트랜스포머 및 회로의 사이즈를 줄임과 동시에 시스템의 경량화가 가능하여 추가적 설계 기법으로 제안한다.

The purpose of this study is to develop a knitwear design with the potential for practical use through a combination of science and design by examining the concept and formative characteristics of fractal geometry and applying them to the development of 3D virtual clothing knitwear design. This study produced five main conclusions. First, the sub-concepts of "Repeatability," "Scale variability," and "complexity," which are based on self-similarity, appear together with simple regularity in the fractal formative characteristics shown in fashion design. Second, fashion fields apply fractal geometry in three-dimensional surface textures and optical textile patterns as a method of expression. Third, it was confirmed that various expressions can be created with fractal patterns by using the SDS-ONE APEX 3-4 design system; moreover, fractal patterns are a suitable design source for the development of Jacquard knitwear patterns. Fourth, in the development of knitted jacquard fractal patterns, by arranging the patterns in perspective, the effect of emphasizing or reducing the human body by optical illusion was shown. Fifth, a knit Jacquard structure with a pattern that exhibits fractal modeling characteristics and applying it to a 3D virtual clothing sample design reduces the time required for sample production while expanding the knit design's expression area and reducing costs. Thus, the clothing sample confirmed the effectiveness of practical knitwear design development.

In this study, a surrogate model is applied to multi-objective aerodynamic optimization design. For the balanced exploration and exploitation, each objective function is converted into the Expected Improvement (EI) and this value is used as fitness value in the multi-objective optimization instead of the objective function itself. Among the non-dominated solutions about EIs, additional sample points for the update of the Kriging model are selected. The present method was applied to a transonic airfoil design. Design results showed the validity of the present method. In order to obtain the information about design space, two data mining techniques are applied to design results: Analysis of Variance (ANOVA) and the Self-Organizing Map (SOM).

Frei Otto, who is called to be the father of the ecological architecture, has shaped a peculiar architectural form style. In distance from the formalistic persistence to the modernist form canon and the postmodern tendencies to the self-representation of architects, Frei Otto has taken a more fundamentalistic position. Through the interdisciplinary researches on the self-organizing processes in the nature and the technical world Frei Otto could reason with architects, engineers, biologists, historians and philosophers the principle and structure of the natural construction that is applicable to the morphological research and the architectural construction research. In the middle of his architectural and scientific works is the idea of 'the natural construction' situated, and the basic principle and instrument of this 'Die Prinzip der Selbstbildung, The Principle of Self-making'. Founding himself on this principle, Frei Otto seeks after the new architectural form that is light, natural, flexible and variable by reasoning the typical formation process which refers to the common denominator of the self-making processes in the nature, the technique and the architecture. Despite his architecture is to be called to the anonymous, his architectural vision is headed toward the rationalistic form in accord with the natural laws. This study is purposed to elucidate the constellation to which his scientific attempts belong and the theoretical and methodological foundations of his architecture of 'the natural construction'.

This study examined the effect of beauty involvement on self-satisfaction by conspicuous consumption tendency groups. A questionnaire method was used for this study. The subjects of this research were females in their 20s~50s. We distributed 580 questionnaires ets; constantly, 554 sets were used in the final analysis. Data were analyzed by factor analysis, ANOVA, cluster analysis, Cronbach's alpha coefficient and multiple regression analysis. Beauty consumption behavior factors were classified with hair styling, skin management, make-up and body shaping. Self-satisfaction factors were classified with living, appearance, economic and interpersonal relation. This study classified 4 conspicuous consumption groups (active, passive, syntonic and individuality & frugal group). The active conspicuous consumption group was unsatisfied with most of the self-satisfaction factors. The passive conspicuous consumption group was more interested in skin management factors than other factors. The syntonic conspicuous consumption group was interested in make-up, body shaping and skin management in order to provide a positive impression to other people. The individuality & frugal group was most interested in body shaping that could be achieved at low cost through exercise and diet.
