If one express the basio equations of electromagne tics in terms of differential form, one can have many physical meanings. To obtain this advantages in Finite Element Method, we should use new element. In this study, we select degree of freedom as circulation A along edges of the mesh, and use Egde Element because A is i-form. We apply this method to some examples of the 3-D magnetostatics, and obtain decrease of total nonzeros and increase of accuracy.

In this paper, we address the development of magnetic levitation positioning system. This planar magnetic levitator employs four permanent magnet liner motors. Each motor generates vertical force for suspension against gravity, as well as horizontal force for driving levitation object called a platen. This stage can generate six degrees of freedom motion by the vertical and horizontal force. We derived the mechanical dynamics equation using Lagrangian method and used coenergy to express an electromagnetic force. We proposed a control algorithm for the position and posture control from its initial value to its desired value using sliding mode control. Some simulation results are provided to verify the effectiveness of the proposed control scheme.

Flapper fashion style is focused on completely denying outdated fashion worn by women in the age right before. Second, pursuit of mature, graceful and classical beauty that had continued in previous ages has gone through complete changes in the flapper era in the name of pursuit of youth, and the flapper fashion expresses sensual image through the exposure of slim arms and legs of a young girl. In the formative characteristics, aesthetic sense of youth and sensuality inherent in the flapper fashion was generated. Third, women's free-spirited lifestyle at that time and 'aesthetic sense of freedom and amusement that reflected the speed of machine civilization could be found in the flapper fashion. Material and decoration of the flapper fashion pertained to clothing that enabled a free expression through rapid movements. Aesthetic sense of the flapper fashion generated in the process could be defined as women's internal determination to express individual and free-spirited ideas through the use of fashion when tradition and order of the old age were torn down.

The purpose of this study is to develop high-valued added socks by utilizing consumer design preference research in design. The study was performed by investigating literatures including previous studies, and researching the recognition and design preference of consumers. As a final step, socks designs were developed to reflect the results of the research. Gender differences have been found in the choice of socks. Women put more importance to the design, color and trend and prefer geometric, animals and plants patterns, and unique images compared to men. In terms of fashion interest level, 'high' group preferred design, color, and trend than 'middle' and 'low' group, and also preferred geometric, abstract patterns. Women's and unisex socks were designed for people in their 20s, the age group with the highest level of interest in fashion, after taking results of the consumer design preference research into account. Main themes for the lady's socks are 'Soft Shape' and 'Line Composition' in order to express delicate, soft sensibility. For the unisex socks, 'Daydreamer' and 'Free Zone' are the themes used to express young energy and the sense of freedom. 12 styles were developed by creating 3 styles per theme using Photoshop CS5 and Illustrator CS5 programs. As a result, it is confirmed that design strategies in segmented market are necessary for the high-valued added products. Also, the understanding of changes in consumer's tastes and needs through regular market research is needed for the competitive socks design planning.

디지털 공간에 익숙한 동시대 관람자들은 자기표현 욕구를 드러내며 의사표현 도구로 음성, 텍스트와 제스처를 많이 이용한다. 본 연구의 목적은 발화한 관람자의 내러티브를 관람자의 모습을 이용하여 콜라주 형식으로 표현하고, 관람자의 움직임에 의한 스토리를 재생산하고 확장하는 인터랙티브 아트의 창작이다. 제안된 인터랙티브 아트는 관람자로부터 획득한 음성, 영상 정보를 텍스트 콜라주로 시각화하고, 제스처 정보와 자연스러운 사용자 인터페이스(Natural User Interface)를 이용하여 쉽고 간편하게 실시간으로 상호작용하며 개인화된 감정을 표현할 수 있도록 한다. 관람자로부터 획득한 세 가지 정보는 서로 연결되어 관람자의 현재 일시적 감정을 표출한다. 텍스트의 경직된 내러티브는 관람자의 초상 이미지와 제스처를 통하여 약간의 자유도를 가지게 되고, 동시에 현실과 밀착된 스토리의 구조를 생산하고 확장해간다. 이렇게 창조된 작품 공간은 실시간으로 관람자의 내러티브를 반영하고 갱신되며 창작되는 체험 공간이며, 자신의 반영이다. 또한 관람자의 능동적인 개입과 행위를 통해 적극적인 감상 행위를 유도해낸다.
