최근 감성연구의 한 측정 방법으로 의미변별 기법을 이용해 형용사를 제시하는 연구가 증가하고 있다. 본 연구는 의미변별 기법을 사용하는 감성 연구의 기초적인 연구로서 우리말 형용사의 전체적인 의미구조를 분석해 보았다. 우리말 형용사의 의미구조는 기존의 다른 언어권에서 얻은 연구결과와 거의 일치하는 것으로 나타났다. 전체 형용사의 의미구조는 다섯 요인으로 나타났으나, 기존 연구들과 마찬가지로 세 요인이 주요 요인으로 작용했다. 한편, 이러한 의미구조가 색채라는 특정 자극과 관련해서 나타나는 의미구조를 파악하기 위해 NCS단색과 형용사 쌍을 사용하여 측정하였다. 색채 이미지와 관련된 형용사의 의미구조도 세부적인 차이는 있으나, 첫 연구에서 발견된 결과와 크게 다르지 않았다. 감성의 표현수단으로서 어휘를 고려할 때, 이 결과는 사용하는 어휘가 다를지라도 기저에 있는 의미구조는 문화에 상관없이 보편적이라는 것을 제시한다. 다시 말해 어휘로 표현되는 감성의 기본구조가 공통적일 수 있음을 제시한다.

본 연구는 색 조명 시각 자극이 정상인의 기억작용에 어떠한 영향을 미치는가를 평가해보고자 하였다. 피험자는 대학생 성인 남, 여 20대 (20-30세) 각각 10명을 대상으로 실시하였으며 자체 제작한 기억 테스트(Memory test)를 활용하였다. 색채 환경은 방음 암실에서 백색광원을 파장대별로 필터링한 색 조명을 사용하여 제시하였으며 실험 측정 파라미터로서는 정확도(accuracy), 반응시간(Response time) 그리고 학습시 주로 활성화 되는 뇌파인 알파와 세타파의 주파수 대역을 측정하여 기억기능을 수행하는 대뇌의 기억 활성화 상태를 색 조명에 따라 비교 분석 하였다. 측정결과 각각의 색조명에 대한 정확도는 파랑색에서 증가하고 반응시간을 노랑과 파랑에서 감소했다. 뇌파의 활성화에서도 흥분이나 긴장을 상징하는 빨강의 색보다는 파랑색과 보라색과 같은 단파장의 색이 알파파나 세타파를 활성화 시키는데 영향을 줌을 알 수 있었으며 이러한 연구가 감성적 색 조명 디자인의 응용이나 색 관련 제품 계발에 적극 활용될 수 있을 것이라 기대된다.

If color and motion direction of random dots in the central region was combined in opposite fashions with those of random dots in the peripheral region, the color of dots with a particular direction in the peripheral region is perceived as that of dots in the central region, known as color-motion mis-binding phenomenon. In the present study, it is investigated whether mis-binding would happen even if the central and peripheral region do not have a common three-dimensional surface. In the first experiment, the dots in the peripheral were presented in a different depth plane with use of binocular disparity, and in the second experiment the disparity of dots in the peripheral region was randomly selected from a given range. The results showed that the magnitude of mis-binding was weakened, but not completely disappeared even when two regions did not have a common 3D surface. These results indicate that the surface information from motion and stereodepth may influence in the process of color-motion mis-binding.

특정 대상 또는 외부 자극에 대해 반사적이고 직관적으로 발생하는 느낌으로 정의되는 감성은 자신의 경험을 바탕으로 개개인이 서로 다른 반응을 보이는 특징을 가진다. 이러한 감성은 맞춤형, 적응형 및 개인화된 서비스를 요구하는 현대사회에서 반드시 필요하고 연구되어야 하는 대상이다. 하지만, 감성은 외부 자극에 따라 빠르게 변하고 객관성을 유지하기 어려울 뿐 아니라 복합적으로 나타나기 때문에 측정하거나 표현하기가 매우 어렵다. 시각정보는 감성을 이해하고 전달하는 데 큰 비중을 차지하며, 대상에 대한 종합적인 정보를 전달하여 빠르게 인지하고 이해하는데 많은 도움을 준다. 그 중 색채정보는 대상의 객관적인 특정, 심리적 속성 및 사회적 배경을 반영할 수 있어 복합적인 감성을 효과적으로 표현하고 전달한다. 많은 연구를 통해 감성과 색채정보 간의 관계를 생성하고 정의하였지만, 단일 시각정보로 감성을 표현하는 것은 한계가 있다. 본 논문에서는 종합적인 시각정보를 고려한 감성연구를 제안하기 위해 대용량의 감성어휘와 이미지를 수집하였다. 감성어휘는 The Center for the Study of Emotion and Attention(CSEA)에서 생성한 균형 감성어휘 중 273개를 사용하였고 감성이미지는 객관성과 공통성을 유지하기 위해 사용자의 참여가 활발하고 이미지에 부착된 태그가 비교적 정확한 Flickr를 사용하여 수집하였다. 감성어휘 당 약 500개의 이미지를 수집하고자 시도하였고, 총 130,944개의 감성이미지 후보를 수집하였다. 한 번 수집된 이미지는 중복을 피하였고, JPEG형식으로 저장되어 있다. 또한, 각 이미지에는 사용자 태그가 평균적으로 약 25개가 포함되어 있고, 총 2,l47,645개의 태그를 수집하였다.

This paper proposes a Image retrieval system that searches the closest images to the user's emotional need and displays images with higher ratings of color harmony from Moon-Spencer's Color Harmony Theory first. Once an emotional adjective is placed, the system searches for images with colors that contain more elements derived from Aesthetic Measure results and displays in such order. In order to test reliability of the proposed emotion retrieval method based on Moon-Spencer's Color Harmony Theory, this study compared the order of Aesthetic Measure results with the user satisfaction ratings using 200 sample images. The analysis demonstrated that the participants' average satisfaction on 15 emotion adjectives selected for the study was 5.0 on a 7-point Likert scale. Correlation analyses were performed to test the consistency the orders between Aesthetic Measure values and user satisfaction ratings. Positive correlations above R=.5 were observed in all 14 emotion words except "Clear". These findings prove the potential of the proposed emotion retrieval system based on Moon-Spencer's Color Harmony Theory to effectively reflect user emotion in such visual stimulus search as image database.

The aim of this research is to find out the flows of mega-trends and design trends by analyzing the factors that influence trend and design trends in the late 20th century. Moreover, it is to forecast and recommend design color trends by evaluating color trends in design trends for the near future. Secondary and primary research were used in parallel. In the late 20th century, mega-trends were analyzed from secondary research based on PEST. Design trends were analyzed from case studies in fashion, space, product and visual design. On this basis, design color trends were analyzed. Also, color trends were forecast for the near future. The results are as follows. Firstly, the main trends in the late 20th century were 'female thinking', 'back to the nature' and 'heaven of peace'. Second, main design trends in the 1970s were modernism, post-modernism and high-tech. In the 1980s, with those of the 1970s, ecology was introduced In the late 1980s. In the 1990s, modernism rose again and ecology had an influence. The trends of 'female thinking' and 'back to the nature' controled the design in the early 2000s. Third, design colors in the late 20th century changed from Red to Purple Blue. Tones changed from 'grayish' to 'dull' Finally, it was forecast that Purple Blue, Yellow Red and Green colors with 'grayish', 'dull' and 'deep' tones were going to be used mainly in the near future. Also, achromatic colors with female and warm nuances would be reflected in design parts. This research will be very useful in that it has built a concrete database reflected on design trends forecasting in the near future by organizing academically a methodology to identify trends reflected on design and identifying relation between mega-trends and design trends based on analyzing factors that influence trend.

Though human being has ability to percept a full colored vision, the technology of early photography only can produce black and white images. For cinema filming imagery also captured mono tone with black and white, until developed a color film technology. The desire for presenting color imagery and the technique for producing film and color ink, photography and print utilize color on it with noticeable color impact to viewers. It, however, abusing fun colors image each and every printed and filmed imagery, the freshness of eye catching power diminished now. On contrast, color becomes black and white or partially used for making discrepancy among full colored images. This image detected commercial and music video, and it spread to film. To use those bleached color images is for evoking a nostalgia and a visual differentiation. Especially, it can be provocative images brought to audience with that. such as "Anycall", "Dimchae" for CF, and "Schindler's list," and "Sin city" for movie. It is hard to investigate on the color studies for partially used images. Therefore, this study is to research that through CF and film, base on it, to investigate the application for this image. To collect data from survey, it will be established a basic concept for understanding the partial color applying.

In this paper, we estimated the effects of different color stimulation on the cognitive function of human quantitatively. For the stimulations we used color lights with 6 color filters such as red, yellow, green, blue, violet and white. The experiment was performed in a soundproof chamber. 50 young male and female subjects were participated in the experiment. To find the appropriate color cognitive function, the endogenous visuospatial attention task(EVAT) and one back working memory task(OWMT) were performed. The reaction time and accuracy degree were measured. The results showed that the reaction time of EVAT was the fastest and the accuracy degree of attention task was the highest in green environment. The reaction time of OWMT was the fastest in yellow and the accuracy degree of memory task was the highest in blue. For physiological parameters, we measured electrocardiogram(ECG) and HRV spectrum analysis, HF/LF color environment. These results can be used as an indicator in the design of color environment and clinical applications.

This study, under the assumption that there may be a difference in colours recognized depending on background lightness and colour stimulus size, applied background lightness in a differential way and conducted an experiment by comparing the sizes of stimuli equivalent to $2^{\circ}$ and $10^{\circ}$. Based on the results, by reflecting the results of this experiment as a difference in colour recognition, which may occur when the input image is converted from a large-sized screen to a mobile-sized screen, power efficiency, one of the biggest issues, can be reflected in mobile devices and may contribute to effective three-dimensional image reproduction and image quality in 3-D or hologram as well as 2-D images.
