COMS(Communication, Ocean and Meteorological Satellite) has multiple payloads; Meteorological Image(MI), Ocean Color Imager(GOCI) and Ka-band communication payloads. MI has 4 IR and 1 visible channel. In order to improve the quality of IR image, two calibration sources are used; black body image and cold space look data. In case of COMS, the space look is performed at 10.4 degree away from the nadir in east/west direction. During space look, SUN or moon intrusions are strictly forbidden, because it would degrade the quality of collected IR channel calibration data. Therefore we shall pay attention to select space look side depending on SUN and moon location. This paper proposes and discusses a simple and complete space look side selection logic based on SUN and moon intrusion event file. Computer simulation has been performed to analyze the performance of the proposed algorithm in term of east/west angular distance between space look position and hazardous intrusion sources; SUN and moon.

The purpose of this study is to understand of future image in fashion for 20C, to suggest a guideline's role in the development on fashion designs study. The methods of this study are used academic literatures as well as practical study. Futuristic image in fashion is to introduce about the future period, as fashion goes ahead times. Trends and formative characteristics of future image in 20C fashion are summarized as follows. First, futuristic images in fashion for 20C had emerged strongly futurism, space look, kinetic look, glitter look, techno look, cyber look. Second, perspectives on response for future society's changes are summarized as follows. Attitude of futuristic images of fashion, futurism, space look, kinetic look and glitter look, had been favorable about future society's changes until 1980. In 1990, techno look had been defensive and cyber look had been aggressive about future society's changes. Third, formative characteristics of future image in 20C fashion are studied shape, material, color, pattern. Shape was preferred linear and geometric form in the first half of the 20C, but body conscious type had appeared often in the second half of 20C. Material maintained the luster or the metal touch. Color was based image of colorless and preferred the gold, silver or color feels like metal. Pattern was preferred clarity with geometric type in the first half of the 20C. On the other hand in the second half of 20C pattern of future image was dominated by vague and abstract chaotic type.

In this paper, a new optical parallel binary arithmetic processor (OPBAP) capable of computing arbitrary n-bit look-ahead carry full-addition is proposed and implemented. The conventional Boolean algebra is considered to implement OPBAP by using two schemes of optical logic processor. One is space-variant optical logic gate processor (SVOLGP), the other is shadow-casting optical logic array processor (SCOLAP). SVOLGP can process logical AND and OR operations different in space simultaneously by using free-space interconnection logic filters, while SCOLAP can perform any possible 16 Boolean logic function by using spatial instruction-control filter. A dual-rail encoding method is adopted because the complement of an input is needed in arithmetic process. Experiment on OPBAP for an 8-bit look-ahead carry full addition is performed. The experimental results have shown that the proposed OPBAP has a capability of optical look-ahead carry full-addition with high computing speed regardless of the data length.

An Asian Ethnic Look is based on its own values of traditional costumes and the fashion accessories that are influenced by its own genre within their own culture. In this thesis, it contemplates the study of visual values and the traditional influences of the Modern Western Designers and Asian Designers' definitions and the considerations of an Ethnic look in the countries like Middle East, India, Korea, China and Japan. The standard procedure to understand their Visual and Aesthetic values is acknowledgement of body. From that foundation, an Asian Ethnic Look and its Visual and Aesthetic Values were researched through out the Middle East Asian Look, Indian Look, Korean Look, Chinese Look and Japanese Look which effective after 1990's. The studies are further researched to the comparisons and interpretations of the Western Designers and the Asian Designers, and the definitions of an Asian Ethnic Look and its Visual and Aesthetic Values in between those. According to each country's religious attitudes, a beauty of concealment and a beauty of negative space appeal which emphasize an ethics on humanity and non-materialistic attitudes. It takes meanings of a phenomenon of nature's worship, Yin-Yang five elements of principles, oneness of body-mind and oneness of universe-mankind. Following the studies of Visual and Aesthetic Values of an Asian Ethnic Look, in 1990's Western Designers' interpretations were prominent use of the Asian Traditional Motif3. However, the interpretations of the Asian Designers were based on their own traditional ethics and they minimized decorative elements but enhanced naturalism, feminism, calm and sober designs compare to the past. The Asian Designers' interpretations of their visual values were based on their Asian mentality, beauty and its straightforward genuine perspective and respects of their own culture.

[ $Courr{\grave{e}}ges$ ]Look style has been showing up continuously since 1980s in the fashion world. In response to that, this study aimed to look into the trend of design in 1960s and examine the formative artistic characteristics in $Courr{\grave{e}}ges$ Look in order to explore the $Courr{\grave{e}}ges$ Look of Andre Courregs. Following the flow of the times, the $Courr{\grave{e}}ges$'s design has transformed and developed through the styles of the pants suit look, the space age look, the mini look and the sporty look. His own style constructed by simple line like a mini skirts, accurate rates, geometric patterns, high tech materials, vivid color and etc, in 1960s. He has also innovated the fields of textile, garment cutting, details, and accessories. The $Courr{\grave{e}}ges$ Style was expressed by pure&avant-garde style, sporty&modern style, cheerful&reveal style and dynamic&funny style. Functionality with humor to $Courr{\grave{e}}ges$ was an important element that expresses both youth and casual. For the active, new woman, not only a funtional beauty but also a futuristic sensibility is expressed in the $Courr{\grave{e}}ges$ Style.

The purpose of this paper is to investigate the changing fashion image of the glossy materials including metal, leather, vinyl, latex, plastic etc. from 1960's to the present. Glossy materials used in the second half of the 20th century showed a restricted image combined with a specific social circumstance. They expressed a reflection of young and future-oriented space period of 1960s. Many designers like Paco Rabanne and Andre Courreges were concerned with the fashion of space age and expressed that image with leather and synthetic materials including silver leather, metal chain armor, and plastic appeared as the keynote of fashion. In 1970's, glossy material was the symbol of avant-garde and rebellious attitude by the punk fashion. They maximized glamourous look of 1980s, and cyber look with an expectation for a new millenium of 1990s. On the other side, glossy materials seem to be used as a source of various inspiration of fashion designer in the 21st century. Also, some of the past images, for example space look and glamourous look, are revived in the 21 st century by the form of modified design.

In this paper, we propose a guidance law to control Impact Angle in consideration of look angle limit of the missile with strapdown seeker on the non-maneuvering target. The proposed law is based on sliding mode algorithm and generates acceleration commands using look angle and line of sight information provided by the strapdown seeker and navigation system. And, target velocity and target path angle are provided by like TADS (Target Acquisition and Designation System) at launch time. We can confirm that the target interception and impact angle control are possible through the convergence of the proposed sliding surface. In addition, it is possible to confirm that the sign of derivative result of the look angle at the maximum and minimum look angle is opposite to the sign of the look angle, so the look angle limit is not exceeded.

This paper proposes a color-matching 3D look-up table that simplifies the complex color-matching procedure between a monitor and a mobile display device, where the image colors are processed in a device-independent color space, such as CIEXYZ or CIELAB, and gamut mapping performed to compensate the gamut difference. The transform from a device-dependent RGB color space to a device-independent color space is implemented by performing display characterization. The mobile LCD characterization error using the S-curve model is larger than the tolerance error since the mobile LCD has the channel-chromaticity-inconstancy and channel-dependence characteristics. In this paper we reduced the characterization error using the electro-optical transfer functions of X, Y, and Z value for R, G, B, C, M, Y, K components. Experimental results demonstrated that 64 ($4{\times}4{\times}4$) was the smallest size of color-matching look-up table that could produce an image with an acceptable reproduction error, based on a comparison of color-matched images resulting from the proposed color-matching look-up table and complex step-by-step color-matching procedures.

The purpose of this is to investigate the relation between Graffiti techniques and the contemporary dress. Graffiti is the internal expression of human potential desires which is composed of informative signs. As Graffiti have become the cross-cultural condition under the Hiphop culture, it makes the meaningless space into the characteristic space, and proposes the identities of graffiti ‘writes’. In the contemporary dress, Graffiti look has become means of communication and playfulness. Through the external forms like icon, index, and symbol, graffiti look expresses individual, social, and political identities, and aesthetic values of satirement and playfulness. It would be define graffiti look as postmodern characteristics, as it wee, which has collapsed between the mainstream, and anti-mainstream, and it contributes to spread streetstyle to catwalk.
