본 연구에서는 사용자 의도를 의도 범위(intention range)에 따라 정의하고, 이를 다양하게 변화시켜 반영한 인터렉티브 사운드 인스톨레이션을 제안한다. 사용자 의도는 요소(element), 부분(part), 전체(entire) 등의 다양한 계층 범위로 분류하여 정의되었다. 또한, 분류된 각 범위는 서로 소속/포함 관계로 정의되었다. 요소 의도를 반영하기 위해 우리는 사용자의 반응에 따라 색과 음이 인터렉티브하게 표시되는 Color note 라는 인터페이스를 제작하였다. 부분 의도를 반영하기 위해 요소 의도를 화성학 규칙으로 보정하기 위한 화성 정리 방법(HD)을 제안한다. 마지막으로 전체 의도는 요소 의도의 거시적 방향성으로써 추정된다. 추정 기법으로서 칼루엔-뢰브 변환(K-L Transform) 등과 같은 통계적 기법을 적용하였다. 제안한 인터페이스인 Color note와 다양한 기법들의 유효성을 확인하기 위해, 전시설치가 되었고, 다양한 사용자에게 평가 설문을 시행하였다. 또한, 전체 의도를 표현하기 위해 사용된 다양한 통계적 기법의 만족도를 조사하였다.

Most people have to deal with color and color problems occasionally. There are many strange things about color and color vision that most people do not notice. Even though color seems intuitive and simple it is not. In this paper, we modeled the color using fuzzy set theory. The proposed fuzzy color model is based on the Munsell color space. We defined several fuzzy color terminologies, and proposed a extended center of gravity defuzzification mthod for fuzzy color set. Finally, three distance measures between fuzzy colors were also formulated.

We have developed the 12.1" SVGA reflective type color TFT-LCD(Thin Film Transistor - Liquid Crystal Display) with the high aperture ratio and well designed reflector for the applications such as mini note PC, Note PC and electronic book. The panel shows the high reflectance(30%) and contrast ratio(20:1) resulted from optimizing the optical films and designing the embossing shaped reflector. By improving the chromacity, the color reproducibility was increased up to 20%. As removing the backlight unit, we reduced the power consumption, thickness and weight of the panel to 0.8W, 2.2mm, and 250gram, respectively. According to the above performances, we have obtained fabrication process for mass production, and furthermore, could have access to fast market launching.

An image obtained from a low light environment results in a low-exposure problem caused by non-ideal camera settings, i.e. aperture size and shutter speed. Of particular note, the multiple color-filter aperture (MCA) system inherently suffers from low-exposure problems and performance degradation in its image classification and registration processes due to its finite size of the apertures. In this context, this paper presents a novel method for the color enhancement of low-exposure images and its application to color shift model-based MCA system for image refocusing. Although various histogram equalization (HE) approaches have been proposed, they tend to distort the color information of the processed image due to the range limits of the histogram. The proposed color enhancement algorithm enhances the global brightness by analyzing the basic cause of the low-exposure phenomenon, and then compensates for the contrast degradation artifacts by using an adaptive histogram specification. We also apply the proposed algorithm to the preprocessing step of the refocusing technique in the MCA system to enhance the color image. The experimental results confirm that the proposed method can enhance the contrast of any low-exposure color image acquired by a conventional camera, and is suitable for commercial low-cost, high-quality imaging devices, such as consumer-grade camcorders, real-time 3D reconstruction systems, digital, and computational cameras.

We have developed 14.1" XGA transflective panel for both transmissive mode and reflective mode. We designed new panel structure, optimized optical films and adopted pixel with high aperture and high transmittance color filter. This can be applied for mobile tool and sub-note without regard to environment.

Pro-environmental life styles, foundations of a collective civilization and preservation of our tradition at rural communities hold a great public profit value, of which importance has been strongly emphasized during last decade. Here, the environmental color is one of the most influential elements that determine the image of the rural landscape. Whenever an alternative color element is introduced to rural town, it is very important to examine its effect on the existing environmental color. Typically, a preference-surveying method has been used to evaluate the suitability of such environmental color balance. However, we note that the reliability of this method is limited by the subjectivity of a respondent. And thus, it is highly desirable to develop a more objective method. We propose a feasibility study for using an aesthetic-measure to evaluate the environmental color of a rural town. In this work, we looked into the validity of our approach by comparing its result with that of the preference-based-method as a way to determine the environmental color. Our study is based on 20 photo images from Ansung-city Yangsung-myeon Donghang 2ri Kyo-dong town in Kyongki Province.

The purpose of this study is that translates ${\ulcorner}$Sun Gi Il Il Bun Wi Sa Si${\lrcorner}$ in the ${\ulcorner}$Young Chu(靈樞)${\lrcorner}$ as a modern words because it is hard to understand which was written by classical words. We revised the original text with the 7 other classic books and classified annotations of the 6 annotated books according to the similar contents. We classified this volume by 3 chapters, and added Hangul suffixes to the original text. The Five types of changes(五變) in the second chapter is meaning to the mutual relationships among the Five viscera and Color, Time, Day, Note, Taste. The word order of contents in the second chapter must be unified follow the Color, Time, Day, Note, Tastes. The Five types of changes in the third chapter must be revise the Five types of diseases(五病) on the bases of the ${\ulcorner}$You Kyoung(類經)${\lrcorner}$.

The authenticity of bank note is threatened by increasing a counterfeit note with development of the information industry, recently. The importance of counterfeit discrimination is stressed, but there is a limits to popularization. Because usually, the existing counterfeit discriminator uses invisible ray zone like UV, IR, etc. The purpose of this paper is the construction of counterfeit discrimination system for \50,000 won bills. This system is used optical fiber sensor with excellent confidence as well as easy way of using in wave length of a visible ray zone. The light was altered by lightening optical fiber sensor to particular part of bank notes in order displacing response of optical fiber sensor. The experiment was processed with data of 100 bank notes on manufacture optical fiber, probe, jig. As a result, the discrimination conuterfeit was verified when the experiment was processing with hologram or CSI on the bank notes with three kinds of color printer.

아티스트에게 음악적 정체성을 가지고 있는가의 여부는 상당히 중요하다. 현재 국내의 대형기획사는 치밀한 기획력과 자본을 바탕으로 음악적 정체성이 없는 아이돌이라는 문화 상품을 만들어내고 있다. 이러한 상황 속에서 자신의 사상과 정체성을 명확하게 드러냈던 아티스트 프린스를 주목해야 할 필요가 있다. 그의 음악적인 천재성과 독특함에 대한 많은 연구는 음악의 본질에 대해 다시금 생각하게 하는 자극제가 될 것이다. 편곡자로의 프린스는 텐션 노트를 효과적으로 활용하고 어보이드 노트마저도 음악적인 색깔로 표현할 수 있다는 것을 보여주었다. 그가 가지고 있는 음악적인 천재성과 독특함에 대한 더욱 많은 연구가 앞으로도 계속 이루어져야 하며, 이러한 연구는 음악공부를 하는 사람들을 비롯하여 대중에게도 음악의 본질에 대해 다시금 생각하게 하는 자극제가 될 것이다. 음악에는 정답이 없고, 그 본질에는 예술이라는 근본이 있어야 한다.

The 1,3-bis(4-aminoaryl)squaraines showed color, change behavior, they were found to undergo reduction with sodium borohydride in solution to give colorless leuco compounds, which oxidized readily in air back to the colored squaraine dye. We have shown that initial observations indicated that the derivatives synthesized gave new donor-acceptor chromophores. It is also interesting to note than the oxidation of the leuco squaraines did initially produce a species absorbing about 630-680 wavelengths. The 1,3-squaraines have found many uses as near-infrared absorbers, laser dyes and photoconductive materials. Furthermore their color-change redox behavior has potential in the area of peroxidase-based bioassaysas oxidation sensitive indicator systems were investigated.
