The idea I set my thesis upon was to develop a methodology for the visually impaired to perceive an environment through their other senses. Since the Blind perceive spatial relationships by combined association of their other senses, it was essential to create a setting where their senses can be amplified. Thus this garden was designed to accommodate two or more of blind person's senses at once to provide more of '3-D' spatial relationship. The main goals of this thesis are, first, to create a place where the Blind can enjoy and nurture their own specific interests. Second, to reveal the nature in its allowing individual analysis and interpretation of a garden. Third, to move away from the prejudice of gardens for the Blind being made of only touching and smelling. To achieve these goals, the most important task was to establish a sense of space. In order to do so, five principles were used; Perspective, Enclosure, Light/Shade, Form, and Environment. After all, the garden for the Blind does not proclaim its purpose in loud terms nor in obvious manner. It should attempt to provide joy, serenity, and activity; a freedom to choose, recognize and analyze nuances of garden, the rhythm of enclosure and openness to experience variety, also to delight in subtle changes and to just imagine.

In this paper, It is examined the patterns of fashion style in the history of subcultural clothing from 1930s to 1960s, focusing on the way each generation resisted the main stream through its styles. The subcultural styles examined and classified in this study are mainly British and American, with a few European and Western Indian styles included. This study understands subcultural style as a way of deviate or resistant expression within a society. The patterns of subcultural styles presented in this study are based on their form of resistance, and they are classified as follows: The pattern is revision, which tries to revise and change the given form by adding new elements. There are two kinds of revision, one is dressing up, which dresses for success, and the other is minimal dressing. Zoot, caribbean, western, teddy boy, rockabilly style are included here. As minimal dressing, there are hipster, beatnik, modernist, mod, rude boy style. In conclusion, it can be said that subcultural style puts the foremost importance on individual freedom. The new and significant development can be found in the fact that subcultural style emerges as a dominating force in our culture. This implies that the energy of a subculture is essential as a formative force of a fashion world.

This paper addresses the issue of position control of a chain of multiple mass-spring-damper (CMMSD) units which can be found in many physical systems. The dynamic model of a CMMSD system with any degrees of freedom is expressed in a closed-form for the convenience of the controller design. Backstepping and model reference adaptive control (MRAC) approaches are then used to develop two adaptive output feedback controllers to control the position of a CMMSD system. The proposed controllers rely on the measurements of the input (force) and the output (position of the mass unit at the end of the chain) of the system without the knowledge of its parameters and internal states. Simulations are used to verify the effectiveness of the controllers

The purpose of this study was to find out the correlation between the spirit of the times and the characteristics of each eras fashionable silhouette and clothing in Gothic and Modern Period. Theoretical studies about the spirit of times, and the characteristics of clothing about each times were preceded. The results were as follows: The similarities of spirit of times were 1) emphasis on reason and rationality 2) centralization by christianity in Gothic Period, and modernism theory in Modern Period 3) times of the nobility and the churchman in Gothic, and elite class in Modern era. The similarities of characteristics of clothing were 1) preference of slim body form as the ideal body figure, 2) emphasis on convenience and function for freedom in action, 3) discontinuation of traditional way of clothing attitude, 4) emphasis on straight and simple on the silhouette and design, 5) tendency of eliminating ornaments on clothing.

In this paper, a geometrically nonlinear meshfree analysis of 3D various forms of shell structures using the double director shell theory with finite rotations is proposed. This theory is introduced in the present method to remove the shear correction factor and to improve the accuracy of transverse shear stresses with the consideration of rotational degrees of freedom.The present meshfree method is based on the radial point interpolation method (RPIM) which is employed for the construction of shape functions for a set of nodes distributed in a problem domain. Discrete system of geometrically nonlinear equilibrium equations solved with the Newton-Raphson method is obtained by incorporating these interpolations into the weak form. The accuracy of the proposed method is examined by comparing the present results with the accurate ones available in the literature and good agreements are found.

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.

Chair is one of objects which are closely connected with human body and is a symbol which represents human essence and culture. Symbolism embodies the meaning of expression through transfering the immaterial structure to tangible form. Therefore chair embodies the essential internal desires of human by means of its symbolic representation. In order to understand the essential human desires included in the symbolism of chair it is necessary to consider these desires with respect to cultural and historical context. in this study four essential internal desires of human are investigated through the symbolic representation of chair that is the desires on human psychological comfort authority freedom and eroticism. The purpose of this study is to emphasize the necessity of the design approach based on the understanding of essential internal desires of human which is pursued from the object by user.

This paper adopts autoregressive (AR) model to simulate the wind velocity of spatial three-dimensional fields in accordance with the time and space dependent characteristics of the 3-D fields. Based on the built MATLAB programming, this paper discusses in detail the issues of the AR model deduced by matrix form in the simulation and proposes the corresponding solving methods: the over-relaxation iteration to solve the large sparse matrix equations produced by large number of degrees of freedom of structures; the improved Gauss formula to calculate the numerical integral equations which integral functions contain oscillating functions; the mixed congruence and central limit theorem of Lindberg-Levy to generate random numbers. This paper also develops a method of ascertaining the rank of the AR model. The numerical examples show that all those methods are stable and reliable, which can be used to simulate the wind velocity of all large span structures in civil engineering.

In the process of die manufacturing, according to increasing demand of die and molds, the efficient machining of dies and molds has been increased. However, while the cutting process has been automated by the progress of CNC(computer numerical control) and CAD/CAM, the polishing process still depends on the experienced knowledge of an expert. Also, even when workers are skilled in polishing dies. it takes much time to obtain the required roughness and smoothness on the surface of a die. Moreover, many workers gradually avoid doing polishing work because of the poor working conditions caused by dust and noise. Therefore, to improve productivity and to solve the potential shortage of skilled workers, a user-friendly automatic polishing system was developed in this research. The developed polishing system with five degrees of freedom is able to keep the polishing tool normal to the die surface during operation and is able to maintain a pressure constantly by the developed pneumatic system. Also, to evaluate polishing performance of the developend system and find the polishing conditions, the various polishing experiments were carried out.
