A new electric coil design methodology using the notion of topology optimization is developed. The specific design problem in consideration is to find optimal coil configuration that maximizes the Lorentz force under given magnetic field. Topology optimization is usually formulated using the finite element method, but the novel feature of this method is that no such partial differential equation solver is employed during the whole optimization process. The proposed methodology allows the determination of not only coil shape but also the number of coil turns which is not possible to determine by any existing topology optimization concept and to perform single coil strand identification algorithm. The specific applications are made in the design of two-dimensional fine-pattern focusing coils of an optical pickup actuator. In this method, the concept of equivalent magnetizing current is utilized to calculate the Lorentz force, and the optimal coil configuration is obtained without any initial layout. The method is capable of generating the location and shape of turns of coil. To confirm the effectiveness of the proposed method in optical pickup applications, design problems involving multipolar permanent magnets are considered.

Modern fashion can be expressed as 'pursuit of cocktail effect', which means not unformed, not bounded by a rule, and mixed with various styles. Among them, the most outstanding trend of style is the'infra-syndrome'which designs underclothes like a ordinary wear, which has outstood since early 1980s. In 1990s, this syndrome made active progress and now facing 21th century, it becomes one of the big trends in fashion. Clothes of infra syndrome are one of attempts for freedom expressed by progressive designers who pursuit new and surrealistic design. The purpose of this study is to maximize the aesthetic beauty of'infra-syndrome'apparel centering on dresses of which designs are notable derived from underclothes. With the sewing techniques using the special facilities of the lingerie-manufacturing industry and making use of new material which can be used far lingerie wear, this research strives to expand new ideas in the lingerie industry as well as to contribute to promoting the dress culture by developing novel lines from a new form of dress and lingerie-foundations of dress suitable for human body.

This study suggests a new paradigm of fashion merchandising as an environmental change of the fashion industry. The study has the pattern of a literature study and it is analyzed through journals, professional books, fashion magazines, and newspapers. Examined are the environmental changes of the fashion industry, the condition, and problems of the merchandising process that is executed currently, as well as an examination of the concept of fashion merchandising, Concepts and changes for new fashion merchandising strategies are suggested that are helpful for academics and fashion companies. This paper defines the concept of new fashion merchandising as the integrated management activity of planning, development, and selling fashion products to create a profit for the company with the satisfaction of the target customers. This study proposes the pursuance of integrated merchandising, the change of product planning and product development, and the strengthening of store-centered retail merchandising in order to change the direction of fashion merchandising.

We propose a new method to eliminate completely the redundant elements in a CDMA (code division multiple access) mobile system. First, we define multilevel logic operation (MLO), which is a new concept to deal with the multilevel logic signals. We prove that the conventional binary logic concept is a subset of the MLO concept. The multilevel logic signal can be directly controlled by using this MLO in place of the binary operation. We applied the MLO to the CDMA base station modulator (BSM) in order to reduce the hardware complexity. In the case of a 3-sectorized cell, this method helps reduce the complexity down the level of below 1% of the conventional CDMA BSM for spreading and filtering, and to 50% for Walsh covering.

Jacques Derrida, a leading theorist of the post-structuralism, has explicated how the material reality is subordinated to the ideality of form, by noticing the platonic concept, 'chora', which implicates the spatiality as the matrix and also by actualizing its essential meaning as the femininity. On the basis of the idea of the platonic 'chora', the Derridian deconstructive spatiality and its feminist oriented enlargement of Grosz this study is purposed to elucidate the architectural idea of Zaha Hadid that is located in the similar horizon with the deconstructionism. On the one hand it is focused on the explication of the new concept of space, which is dealt with the deconstruction of the traditional concept of space, on the other on the inference of the feminity of the originally understood spatiality. With this inference it is finally intended to reexamine the foundation of the discussion for the architectural space that must be ahead of the discussion for the difference between the masculine and the feminine space. If it is fundamentally and manifoldly executed, not only the architectural paradigm will enter into an renewed phase, but also the various ways toward the new direction of the architecture be explored.

There is so much difference in the way we perceive nature whether from eastern or western, present or past standpoint. however, awareness of coexistence between human beings and nature along with the concept that the most natural is th e most beautiful remain unchanged. The desire to describe the beauty of nature have existed all through the ages, but the (new) naturalism movement was spawned in our time when so much devastation and side effects took place for the expediency of nature, and field of display has been trying new interpretation of nature with direct or applied method. Naturalism trend is studied using the categories such as relationship between human and nature, space concept in western and eastern society, and the definition of view of nature in modern time. Elements of naturalism display are classified into the element of physical properties and element beyond the physical properties, and then methodology on naturalism display is investigated, using the illustration of display examples, in order to know the most essential elements of display, which are the physical properties such as space, light, object, glass, are expressed based on the elemental concept like nature, an accident, dynamic state, variability. As mentioned above, Naturalism display consists of physical properties and phenomenon. How to ive strong impression to a spectator depends on the ability to create effective space applying these elements. The significance of this study comes to surface in a time when the tremendous emphasis is put on the importance of nature and concerns about the role of display has become even greater.
