With Expo 2012 Yeosu to be held in 2012, this study intends to propose designs for fashion cultural products into which the characteristics of local cultures of Yeosu are fused. Using symbols of Expo 2012 Yeosu and cultural symbols of Yeosu City as motifs, this study will develop patterns and then, apply them to neckties, handkerchiefs, and T-shirts. Adobe Illustrator CS2 and Adobe Photoshop CS2 will be used. This study developed basic motifs so that cultural resources using camellia, Odong Island, and the Turtle Ship, which represent Yeosu City, could be well harmonized with the topic of Expo 2012 Yeosu. This paper set three basic motifs of new formative images, using graphic images that were made by omission of forms, simplification, overlap, repetition, and calligraphy of the name of Yeosu holding the event. Each set motif was expanded to three motifs again through change, conversion, and mixture of colors, and three types of repetitive applied patterns were developed through revolution, symmetry, repetition, and reversal of each motif. The modern and refined image for neckties, to which the developed motif was applied, was made by directly applying the repetitive pattern of each motif or by making $45^{\circ}$ revolution. For handkerchiefs, revolution, enlargement, reduction, and gradation were applied to the motif so the pattern could be highlighted to the maximum and finally, a colorful image was developed. For T-shirts, three designs-a half-sleeved box type, a sleeveless round neckline type, and a sleeveless V-neckline tight type-were developed, through which availability of the design was increased. Through enlargement, reduction, revolution, and repetition of each motif, this paper layout the pattern on the whole part of a T-shirt, pursuing a decorative and casual image.

일반적으로 근대 디자인의 역사는 19세기 중반 영국에서 시작된 것으로 이해되고 있다. 이 시기의 유럽은 프랑스 혁명과 한업혁명을 거치면서 성장한 부르주와 계층이 역사의 전면에 부상하며 과거 봉건적 전퉁사회와는 전혀 다른 근대사회를 성립해가고 있었다 새롭게 사회의 주역으로 부상한 부르주아 계층은 그들만의 고유한 새로운 미학을 확립하고자 했고 이러한 과정에서 근대 디자인이 탄생하게 되었다. 본 연구에서는 지난 150여 년간의 디자인의 역사를 근대 프로젝트로서의 디자인 혹은 모던 디자인 프로젝트라는 관점에서 파악하고자 한다. 초기 근대 디자인 이념의 형성과정에서부터 최근의 탈근대 논의에 이르기까지의 디자인 역사를 모던 디자인 프로젝트의 형성과 변질, 그리고 이에 대한 비판과 재평가라는 맥락에서 이해하고자 하는 것은 이ㅓ한 논의가 현재 진행중인 탈근대로의 급격한 전환과정을 이해하고 미래에 대한 전망을 갖게 하는데 도움이 되기 때문이다.

전도성 물질인 철 입자(iron particles)를 절연체로 코팅하여 제작한 압분자심(powder core)은 비저항이 작기 때문에 고주파 영역에서 와전류 손실이 크다. 이 결함을 해결하기 위해서는 압분자심의 비저항을 증가시킬 필요가 있다. 이 연구에서는 압분자심의 비저항을 증가시키기 위하여 유성볼밀을 사용하여 전기전도성 철 입자에 산화제2구리를 코팅하였다. 반응표면분석법을 사용하여 코팅변수를 최적화하였다. 최적화 시 인자는 CuO 질량분율, 밀 회전 수, 코팅시간, 볼 크기, 볼 질량, 시료 질량이며, 반응변수는 비저항이었다. 6인자-일부요인배치법에 의하면 주된 인자는 CuO 질량분율, 밀 회전 수, 코팅시간이었다. 3-인자 완전요인배치법과 최대경사법을 사용하여 3개 인자의 수준을 선정하였다. 최대경사법을 사용하여 최고의 비저항을 갖는 영역에 접근하였다. 최종적으로 Box-Behnken법을 사용하여 스크린한 인자들의 반응표면을 분석하였다. Box-Behnken법 결과에 의하면 CuO 질량분율과 밀 회전 수가 코팅공정 효율에 영향을 주는 주요 인자이었다. CuO 질량분율이 증가함에 따라 비저항은 증가하였다. 그에 반해서 밀 회전 수가 감소함에 따라 비저항은 증가하였다. 코팅공정을 최적화한 모델로부터 계산한 예측값과 실험값과는 통계적으로 유의하게 일치하였다($Adj-R^2=0.944$). 비저항의 최고값을 갖는 코팅조건은 CuO 질량분율은 0.4, 밀 회전 수는 200 rpm, 코팅시간은 15분이었다. 이 조건에서 코팅한 정제의 비저항 측정값은 $530k{\Omega}{\cdot}cm$이었다.

Increased internet use under a ubiquitous environment may be called as a great human information space revolution followed by Industrial Revolution. This revolution is exerting its significant influence over all the industry as a whole with speed faster than that of any other times. Along with this trend, if furniture design field that leads living culture should fail to jump on this main stream without noticing it, it may be reduced to a unpopular field some day without any sign of recovery. Under this background, this study is intended to recognize a goal aiming at understanding our rapidly changing living environment and leading our way positively. Currently, our surrounding living environment is immersed in computers here and there and Mark Weiser once defined a system that moves in advance before an action as ubiquitous computing and in this respect, I am going to observe a detailed transformation process of space. First nature of the space may be defined as atoms, a physical space equivalent to a spatial element and Bits space that is untouchable is usually called as 2nd space and a combination of atoms and Bits is an intelligent space - 3rd space - that can be intelligible without touching it and finally, this space is called as a ubiquitous space. This spatial transformation is developed by several changes of living environment and we may call it as living trend or interior design trend. Transformation in terms of social perspective, space structural perspective and digital technique perspective may be enumerated. These transformations were surveyed based on its contents being implemented at a future housing exhibition hosted by 5 construction companies along with fusion of information furniture and furniture depending on each housing space. In conclusion, it could be realized that most of the companies were decorating future space by implementing ubiquitous environment as a success factor of future housing market. It may be meaningful to note once again that under an interior environment, a fusion of furniture and information furniture is required considering interior trend elements.

The painting style has much influenced on the creativity of design in the developmental process of modern fashion. This fact tells that pure art and fashion design have the same purpose in the end. In this paper. the color Autonomy of Matisse was analyzed and how its result influences on modern fashion design was investigated. Matisse is, in fact. the leader of Fauvism and the painter who brought the Fauvism painting to its perfection in the purest state. Matisse achieved the revolution of new color with only the color in expressing formative factor. Matisse's color autonomy are fusion technique, flatness, decoration, simplicity, etc. To sum up the influence that this autonomy played on modern fashion design, intensive pure color expression, strongly-supplemented color effect among primary colors, decoration of color, simplicity of color, that is to say. he gave rise to the revolution of color, Many modern designers are applying this method to the theme of fashion and motive, color the technique of expression. Thanks to this. the new formative artistic expression could be adapted in fashion, and it also induced the inspiration of original design, with great contribution to bringing the era of its own distinct individualism in modern times.

Recently, the industry actively adopts the cutting-edge technologies of the fourth industrial revolution and uses them to enhance the productivity and service of mass-customization. The manufacturing industry is creating new processes and business models by achieving digital transformations through a lean start-up approach aimed at achieving the highest customer satisfaction with minimal resources. Although attempts are made to manufacture the building by introducing the latest technology in architecture, it is applied sporadically, not as an integrated system, in the entire phase of the architectural project. This paper analyzes the changes in the construction industry through the application of core technologies of the fourth industrial revolution. Design processes are analyzed for the digital transformation of the construction industry by case study of advanced architectural design practice. A novel design concept model 'Architectural lean startup' is proposed by combining the architectural process and the lean start up method. Through the design of the bus stop based on the architectural lean startup concept, it is confirmed that the designer repeats the 'Generate-Test-Analysis' to develop the design and generate the final result.
