People have more expectations for arts and design and accordingly, various artworks were combined with fashion to meet the consumer needs. As people live a decent life, the development of leisure activities and industry has a much effect on apparel. With this phenomenon, a free and active casual look is making progress centering around the practical apparel, pursuing diversified efficiency irrespective of a season and considering sensibility not formality. In this study, paintings of Henri Matisse were analyzed in every respect and were applied in apparel design with diverse color arrangement and a motif originating in the phenomenon of modern fashion design which leads to the integration of arts and design. Painting image and color of Henri Matisse were used. Sportive casual and cultural casual was used in design as well. Originality of its color in the paintings which were used an a motif is coming from Gauguin and Gogh. Henri had influenced to the next generation with pursuit of violent color. The following conclusions were drawn from this study. First, the color of Henri Matisse's paintings has a strong contrast effect. It combines notable violent color with a simple yet decorative motif. Therefore color from Matisse's paintings suit for apparel of marked individuality with its free color arrangement. Second, free and active image in Henri Matisse's paintings is easy to express efficiency and popularity. It accords with the feature of casual wear. Third, through adding a flowing curved line in Henri Matisse's paintings to materials and applying various colors putting into a curved line image to a rib section, a decorative effect which goes with the whole shape is obtained. This study presents possibility of emergence of unique design using free color arrangement and motif from the image of paintings and aims development of modern fashion design in accordance with modern fashion giving importance to the difference and sensibility by integration of modern garments and artworks.

This research aims to design a new style jacket by developing patterns with dart manipulation, to achieve a tailored jacket which has been familiar to us, but with a more creative design. Tailored jackets has been widely worn both by women and men, and used to create various fashion styles. Generally the classic design with a basic lapel and collar is worn the most, and this shows demonstrates an importance of its design. Giacomo Manzu's work of relief art inspired for a creative design of tailored jackets. As a result of the analysis on the visual properties of the relief sculptures, it was found that an omissions of line for cubic effect and dramatized expression give an illusion effect. Based on the illusion effect shown in the case of a relief design, it was patterned and designed with dart manipulation. Through dart manipulation, the shape of a lapel was designed to meet the rear collar, which corresponds to a background plane, by making it like a sculpture at the front background pattern. Then it was found through dart manipulation could be extensively applied for various designs, as well as used to generate massing. Hopefully this creative pattern and design development would be helpful not only in diversification of consumer's needs, but also in the educational field for pattern and development of the fashion design industry.

최근 국내에서 장대교량의 건설이 증가함에 따라 그에 대한 내진설계의 중요성도 증대되고 있다. 이와같은 여건을 반영하여 새로 개정된 케이블 강교량 설계지침(안)의 내진설계편에서 지진파의 파동전달효과와 지반특성효과를 일부 반영하였다. 본 연구에서는 국내 설계규정에 따라 사장교(주경간500m)의 다양한(균등입력, 파동전달효과, 파동전달효과+지반특성효과) 지진응답해석을 수행하여 설계적용시 문제점에 대하여 검토해 본 결과 장대교의 파동전달효과는 지지점간 거리가 짧은 경우에도 지반이 연약한 경우 큰 영향을 받는 것으로 나타났다. 한편 지반의 종류에 상관없이 파동전달효과와 함께 지점별로 지반특성을 고려한 해석이 그렇지 않은 해석결과보다 큰 값이 산출되었다. 따라서 장대교의 지진응답해석시 파동전달효과 및 지반특성효과의 적용에 대한 세심한 고려가 필요한 것으로 판단된다.

A kind of Subjective Imaging Effect Assessment (SIEA) method and its applications on intelligent imaging terminal design in engineering site are presented. First, some visual assessment indices are used to characterize the imaging effect: the image brightness, the image brightness uniformity, the color image contrast, the image edge blur, the image color difference, the image saturation, the image noise, and the integrated imaging effect index. A linear weighted function is employed to carry out the SIEA computation and the Analytic Hierarchy Process (AHP) technique is used to estimate its weights. Second, a SIEA software is developed. It can play images after the settings of assessment index or assessment reaction time, etc. Third, two cases are used to illustrate the application effects of proposed method: the image enhancement system design for surveillance camera and the imaging environment perception system design for intelligent lighting terminal. A Prior Sequential Stimulus (PSS) experiment is proposed to improve the evaluation stability of SIEA method. Many experiment results have shown the proposed method can realize a stable system design or parameters setting for the intelligent imaging terminal in engineering site.

In may experimental situations, whenever a block design is used, the block effect is usually considered to be fixed. There are, however, experimental situations in which it should be treated as random. The choice of a blocking arrangement for a response surface design can have a considerable effect on estimating the mean response and on the size of he prediction variance even if the experimental runs re the same. Therefore, care should be exercised in the selection of blocks. In this paper, in the presence of a random block effect, we propose a graphical method or evaluating the effect of blocking in response surface designs using cuboidal regions. This graphical method can be used to investigate how the blocking has influence on the prediction variance throughout all experimental regions of interest when this region is cuboidal, and compare the block effects in the cases of the orthogonal and non-orthogonal block designs, respectively.

디자인에 대한 중요성에도 불구하고 제품디자인에 대한 소비자의 행동적 반응과 관련된 연구는 상당히 부족한 실정이다. 특히 제품디자인에 대한 소비자의 심리적 반응에 대한 실증적 연구는 매우 부족하다. 따라서 제품디자인에 대한 반응과 브랜드 이미지나 브랜드 자산간의 관계에 대한 이해가 매우 제한적이라 할 수 있다. 본 연구는 제품 디자인에 대한 소비자의 심리적 반응을 통해 형성되는 디자인 이미지가 브랜드 이미지와 브랜드 자산에 어떠한 영향을 미치는지를 두 가지 제품 범주(효용제품과 상징제품)를 이용하여 검증하였다. 연구결과 두 가지 제품 범주 모두에서 제품 디자인 이미지는 브랜드 이미지에 긍정적인 영향을 미치는 것으로 나타났다. 또한 상징적 제품에서 디자인 이미지가 브랜드 자산에 영향을 미치는 것으로 나타났다. 그러나 효용 제품의 경우에는 제품 디자인 이미지가 브랜드 자산에 유의적인 영향을 미치지는 못하는 것으로 나타났다. 또한 두 제품군 모두에서 브랜드 이미지는 브랜드 자산에 유의적인 영향을 미치는 것으로 나타났다.

Many thermal-hydraulic tests have been conducted at the Korea Atomic Energy Research Institute for verification of the SMART (System-integrated Modular Advanced ReacTor) design, the standard design approval of which was issued by the Korean regulatory body. In this paper, the contributions of these tests to the standard design approval of SMART are discussed. First, an integral effect test facility named VISTA-ITL (Experimental Verification by Integral Simulation of Transients and Accidents-Integral Test Loop) has been utilized to assess the TASS/SMR-S (Transient and Set-point Simulation/Small and Medium) safety analysis code and confirm its conservatism, to support standard design approval, and to construct a database for the SMART design optimization. In addition, many separate effect tests have been performed. The reactor internal flow test has been conducted using the SCOP (SMART COre flow distribution and Pressure drop test) facility to evaluate the reactor internal flow and pressure distributions. An ECC (Emergency Core Coolant) performance test has been carried out using the SWAT (SMART ECC Water Asymmetric Two-phase choking test) facility to evaluate the safety injection performance and to validate the thermal-hydraulic model used in the safety analysis code. The Freon CHF (Critical Heat Flux) test has been performed using the FTHEL (Freon Thermal Hydraulic Experimental Loop) facility to construct a database from the $5{\times}5$ rod bundle Freon CHF tests and to evaluate the DNBR (Departure from Nucleate Boiling Ratio) model in the safety analysis and core design codes. These test results were used for standard design approval of SMART to verify its design bases, design tools, and analysis methodology.
