As chemistry dyes has considerably developed with industrial society, natural dyeing has gone out of people's head for a long time. But the serious problems from environmental pollutions and ecological damages make people look far Well-being. Natural dyeing also has concentrated again and the interests about it are growing larger and larger. Well-being that a modern person pursues and a Natural dyeing walk along a same string of connection. That is, people want their life to change from quantity matters into qualities. The relations of the natural dying which has the color of nature and Well-being phenomenons are analyzed through dissertations and references. The study about the correlations between natural dying and well-being shows that many advantages of natural dyestuff and the effects of dyestuff are definitely needed to people living in modern times. Also for the protection of an ecosystem, rapid popularization and the development of new design is completely required.

The purpose of this study is to propose a topological design principles and to analyze the space of digital architecture applying topological invariant expressive characteristics. As this study is based on topology as a science of true world's pattern, we intented to explain the concepts and provide some methods of low-level and hyperspace topological invariant Properties. Four major aspects are discussed. Those are connection theory, boundary concept, homotopy group, knot Pattern theory as topological invariant properties. Then we intented to make understand topological characteristics of the Algorithms, luring machine, cellular automata, string theory, membrane, DNA and supramolecular chemistry. In fine, the topological invariant properties of the digital architecture as genetic algorithms based on self-organization and heterogeneous networks of interacting actors can be analyzed and used as a critical tool. Therefore topology can be provided endless possibilities for architecture, designers and scientists intended in expressing the more complex and organic patterns of nature as life.

Emergent computing paradigms such as genetic algorithms have found increased use in problems in engineering design. These computational tools have been shown to be applicable in the solution of generically difficult design optimization problems characterized by nonconvexities in the design space and the presence of discrete and integer design variables. Another aspect of these computational paradigms that have been lumped under the bread subject category of soft computing, is the domain of artificial intelligence, knowledge-based expert system, and machine learning. The paper explores a machine learning paradigm referred to as teaming classifier systems to construct the high-quality global function approximations between the design variables and a response function for subsequent use in design optimization. A classifier system is a machine teaming system which learns syntactically simple string rules, called classifiers for guiding the system's performance in an arbitrary environment. The capability of a learning classifier system facilitates the adaptive selection of the optimal number of training data according to the noise and multimodality in the design space of interest. The present study used the polynomial based response surface as global function approximation tools and showed its effectiveness in the improvement on the approximation performance.

This study is to research the types and formation of the pieces for fastening the clothing in the western and oriental world from 18c to 19c. The pieces for fastening the clothing, depending on their formation, are classified as the ribbon type, the belt type, the button type, and the compound type. The ribbon type indicates fastening the clothing with the strips attached to the clothes. It is divided into the symmetry type and the asymmetry type by the looks of the ribbon alter it is tied. The belt type means fastening the clothing with a string or a belt, separated from the clothes. It is divided into the string type and the belt type. The button type is to fasten the clothing with buttons, button holes, and hooks. It is divided into the basic type, the wrapping type, and the knot type. The compound type is a mixture of two or three types out of the ribbon type, the belt type, and the button type. The pieces for fastening the clothing has aesthetic features as well as their functional characteristics. It has beautiful features like the harmonious beauty of Yin and Yen shown in the asymmetrical types, the beauty of spell wishing for health, long-life, wealth, wisdom, and so on, the beauty of decency showing the intention of refraining from exposing their body in public, the beauty of eroticism emphasizing the beauty of the human body, and the beauty of representing their social class, authority, affiliation, and so on.

딥러닝을 기반으로 한 음성 인식 기술이 상용 제품에 적용되기 시작했지만, 음성 인식으로 분석된 텍스트를 효율적으로 처리할 방법이 없기 때문에 VR 컨텐츠에서 그 적용 예를 찾아 보기는 쉽지 않다. 본 논문은 문장의 형태소를 분석하는 형태소 분석기와 챗봇 개발에 주로 이용되는 검색 기반 모델(Retrieval-Based Model)을 활용하여 명령어를 효율적으로 인식하고 대응할 수 있는 한국어 텍스트 명령 시스템을 제안하는 것을 목적으로 한다. 실험 결과 제안한 시스템은 문자열 비교 방식과 같은 동작을 하기 위해 16%의 명령어만 필요했으며, Google Cloud Speech와 연동하였을 때 60.1%의 성공률을 보였다. 실험 결과를 통해 제안한 시스템이 문자열 비교 방식보다 효율적이라는 것을 알 수 있다.

This thesis that is written by inquiring the shoes of 1990's, is written in order to propose the method of analyzing the changes of shoes design systematically. The picture to be gathered was a content analysis low at ARS and Accessory Collegioni since though the research method took shoes to $1990{\sim}1999$. I categorized the design factors into shape, material, color, decoration. by using those category, the result of analysis of design character. In 1,990's, boots, pumps and straps were the most popular in upper, point and rounded cuban and french were the most popular in toe, leather was the most popular in materiel, suede in F/W and patent in S/S. Black was the most popular color, brown in F/W and white/beige in S/S were the second. Re-created shape that was constructed through the reconstructions of structures and shapes of shoes, shape that was expanded to other genre were appeared in character of design factor. Material image was strengthened by varying patterns of unburned calf, leopard and zebra. Recognition of shoes color was expanded by using unique colorations and abstract, fresh figure colors. Post-modem tendency was appeared like using brassiere strap instead of back strap or using round string in elegant shoes.

This study focuses on the bag design as a creative design resource rather than on typical bag design as shown in previous research. 1'he purpose of this study is to develop creative and harmonious upper garments in good combination of bags and the sides of clothing. This study was performed with female college students whose age are front 18 to 24. The results of this study are as follows. First, bags are ideal for creative fashion in respect that they reflect modern trend. Second, ornamental materials such as string, chain, and buckle, which used to be details of clothing, are useful to present the characteristics of bags more effectively. This result has shown that details of bags are important determinant of entire fashion details. Third, it expands the sphere of expression of the bag, so the possibility of expansion to a distinguished expression of fashion design is recognized. From the study, we understood the structural characteristics and changes of detail of bags, proposing that the bags take important part in fashion design developments.

Evolutionary Algorithms (EAs) cover all the applications involving the use of Evolutionary Computation in electronic system design. It is largely applied to complex optimization problems. EAs introduce a new idea for automatic design of electronic systems; instead of imagine model, ions, and conventional techniques, it uses search algorithm to design a circuit. In this paper, a method for automatic optimization of the digital circuit design method has been introduced. This method is based on randomized search techniques mimicking natural genetic evolution. The proposed method is an iterative procedure that consists of a constant-size population of individuals, each one encoding a possible solution in a given problem space. The structure of the circuit is encoded into a one-dimensional genotype as represented by a finite string of bits. A number of bit strings is used to represent the wires connection between the level and 7 types of possible logic gates; XOR, XNOR, NAND, NOR, AND, OR, NOT 1, and NOT 2. The structure of gates are arranged in an $m{\times}n$ matrix form in which m is the number of input variables.
