To get a variety of colors on silk fabrics with natural dyes, mordanting and combination dyeing were carried out. Gromwell, sappan wood, safflower were used as the three primary colors for combination dyeing. Metal compounds containing alum and iron were used as mordanting agents. In combination dyeing of safflower and sappan wood, safflower and gromwell, gromwell and sappan wood, various colors were obtained according to the content of dyes used. Safflower/sappan wood dyeing showed different colors between yellow red and red purple of Munsell color circle such a YR, R and RP. And safflower/gromwell dyeing showed R, RP, P and PB Munsell color circle and then gromwell/sappan wood showed R, RP and P. As the result of these experiments, wide range of colors (YR-R-RP-P-PB-B) were obtained according to various mixing portion of safflower, gromwell, sappan wood, dyebath pH and repetition dyeing.

The aim of this study was to elucidate the difference in the amount of phytochemicals and anti-oxidant activities of the freeze-dried 5th instar 3rd day silkworm powder (FDSP) and 7 HongJams (HJs). Three primary colors of light of 8 silkworm powders revealed why each sample had unique color. The visual and absorption spectrum analyses of 80% methanol (MeOH) extracts of 8 silkworm powders revealed that white jade (WJ)-FDSP extracts showing strong forest-green colors had different absorption spectrum from 7 HJs. Among 7 HJs, the absorption spectrum of light green silkworm (LGS)-HJ extract was different from those of other HJ extracts. The amounts of total flavonoids and phenolic compounds of WJ-FDSP were 423.0±9.21% and 252.3±12.86%, respectively, more than those of WJ-HJ. Among 7 HJs, the amounts of total flavonoids and phenolic compounds in LGS-and red silkorm (RS)-HJ extracts were significantly more than those of WJ-HJ extract. Consistent with the amounts of phytochemicals, radical scavenging activity and reducing ability of WJ-FDSP extract were significantly higher that other HJ extracts. Among 7 silkworm powder extracts, LGS-HJ extract showed significantly higher radical scavenging activity and reducing ability than those of WJ-HJ extract. But, RS-HJ extract only showed significantly higher radical scavenging activity than that of WJ-HJ extract. Taken together, the amounts of phytochemicals in 8 silkworm powders contributed on their colors and anti-oxidant activities.

People are making multilateral efforts to create beautiful agricultural landscapes. In farming villages, however, large-scale facilities or houses do not blend in with the natural environment because of their outer colors, which are mostly primary colors that are not chosen in consideration of the natural environment. This was addressed in the three following steps: 1) Research tool was used to identify predominant colors and images that represent various types of rural areas; 2) landscape experts conducted a feasibility study and pilot study on using these colors; and 3) the main study was done by investigating how local people and out-of-town visitors perceive the colors. The villages involved in the development projects were mostly represented by achromatic colors, meaning white, black, and variations of gray. Also, adjectives such as "modern" were shown to be keywords that symbolize the atmosphere. Less developed villages had more greenish colors and "natural" as their keyword. Developed villages in suburban areas were mainly represented by shades of blue and green, while less developed ones were mainly represented by green and yellow. In special types of rural areas, developed and developing were represented by achromatic and green colors, whereas less developed ones were represented by green and blue. Respondents were also asked 1) whether they were satisfied with their village's current overall color scheme and 2) whether they thought there was harmony between the surrounding natural environment and artificial structures. People responded with "so so" for the first question, while some answered "not good enough" and "no" for the second.

The internal core material and external color of a sandwich panel have a significant impact on the performance of the sandwich panel. For use on roofs and walls, the internal core material and external color must be considered. Therefore, the surface and back side temperatures were measured for each exterior color and inner core material type. For the internal core materials, urethane foam and Expanded Poly Styrene(EPS), which are core materials mainly used in sandwich panels, were selected. As colors, black and ivory were selected according to brightness, and a total of five colors were selected: red, blue, and green, which are the three primary colors of light. As a result, there were differences in surface and temperature depending on the external color and type of internal core material. Regardless of the color, the temperature was measured lower for panels with urethane foam than for panels with an internal core of EPS. This is believed to have been influenced by the difference in thermal conductivity of urethane foam being 0.023W/(m·K) and that of EPS being 0.032W/(m·K). In addition, panels with a black exterior color were found to have higher surface and back temperatures than panels of other colors, and ivory-colored panels had lower back temperatures regardless of the core material. This is proportional to the brightness and light-absorbing characteristics.

본 연구는 조선시대의 대표적 별서정원인 소쇄원을 사례로 전통 공간에서 나타나는 기호 및 기표로서의 상징적 색채발현 분석 및 그 의미 해석을 통해 작정 의도와 색채와의 관련성 분석을 목적으로 수행하였다. 전통 색채 및 소쇄원의 작정배경 등에 대해서는 관련 문헌연구를 통해 수행하였으며, 실증적 분석 대상으로서의 내용은 소쇄원도와 소쇄원 48영 시문에서 나타나는 경관 및 공간 요소 그리고 음양오행사상(陰陽五行思想)에 근거한 오정색과 관련한 작시의 내용을 대상으로 하였다. 특히, 소쇄원에서 나타나는 공간적 요소를 크게 시각적, 공감각적, 상징 인식적 공간 요소로 구분하여 시각적 공간으로 공간 및 경물의 위치와 방위, 공감각적 공간으로 계절과 시간 및 오관, 상징 인식적 공간으로 칠정과 사단 등으로 구분하고 각각의 공간요소에 대해 오정색 체계 분석을 통해 작정 의도와 공간 의미의 상관성 여부를 분석하는 방법을 통해 연구를 진행하였다. 소쇄원의 3개 공간 구성을 기준으로 색채를 분석한 결과, 모두 74개의 오정색 항목이 도출되었다. 첫째, 시각적 공간 구성요소에서는 청색 2회, 적색 1회, 황색 6회, 백색 4회, 흑색 5회 등 모두 18회의 오정색 요소가 나타났다. 이 분석 결과에서 자연과 생명을 상징하는 청색과 적색보다도 만물의 근본을 상징하는 황색과 깨끗함과 순결을 상징하는 백색이 상대적으로 높게 나타난 것은 양산보의 소쇄원 작정 의도가 자연을 즐기는 데 우선을 두기보다는 오히려 정의롭지 못한 세상에 대한 작정자의 순결한 의지를 상징하기 위한 의미와 연결되어 있는 것으로 해석될 수 있었다. 둘째, 소쇄원 48영에서 주로 추출된 공감각적 공간 구성 요소에서는 청색 11회, 적색 8회, 황색 4회, 백색 5회, 흑색 10회 등 38회의 오정색 요소가 나타났다. 여기서는 자연과 생명을 상징하는 청색과 적색이 세상의 근본과 순결 그리고 지식을 상징하는 황색과 흑색보다 높게 나타남으로써 비록 작정자의 세상에 대한 순결성을 지키고자한 의지로 공간을 작정하였지만, 별서정원에서 자연 즐김과 지식 탐구에 대한 감정을 누리려는 별서 고유의 기본적 기능에 충실하고 있음을 의미하고 있는 것으로 해석되었다. 마지막으로 역시 48영에서 주로 추출된 상징 인식적 공간 요소에 대한 오정색은 청색 4회, 적색 5회, 백색 9회 등 18회가 나타나는 것으로 분석되었다. 이 색채 분석 결과에서는 정치적 순결을 상징하는 백색이 자연과 생명을 상징하는 청색과 적색과 같은 빈도로 출현하고 있음으로써 소쇄원의 작정 의도가 시를 통해 정치적 순결성 강조와 자연 즐김을 동일한 비중으로 감정적으로 드러내고 있는 것으로 해석되었다. 특히, 이 3종류의 분석에서 공감각적 공간 구성요소에 대한 오정색의 빈도가 38회로 약 51%로 가장 높게 나타나고, 시각적 공간 구성 요소와 인지 상징적 공간 구성 요소가 각각 18회로 각 24.5%의 빈도 분포를 보이고 있다. 이러한 현상은 양산보의 소쇄원 작정 의도는 전체적으로 보면, 정의롭지 못한 세상에 대한 작정자의 순결성을 지키고자 함과 함께 별서정원의 기본인 자연과 자연의 생명력을 즐기려는 의도가 같은 비중으로 숨어있음을 상징하고 있다고 해석을 될 수 있었다. 본 연구는 소쇄원 작정의 상징적 의미와 공간 구성 요소와의 상관성을 음양오행설(陰陽五行說)에 근거한 오정색을 기준으로 분석함으로써 전통 별서정원에서 숨어있는 전통 색채를 밝히고자 하였지만, 이러한 이론이 다른 별서정원에서도 일반적으로 적용될 수 있을 것인지를 탐색하는 것은 소쇄원과는 다른, 순수한 자연 즐기기나 강학, 기능 등 뚜렷한 작정 의도가 숨어 있는 다른 사례의 별서정원에 대한 연구를 통해 밝혀질 수 있을 것으로 사료된다.

In order to realize full color display, two approaches were used. The first method is the patterning of red, green, and blue emitters using a selective deposition. Another approach is based on a white-emitting diode, from which the three primary colors could be obtained by micro-patterned color filters. White-light-emitting organic light emitting devices (OLEDs) are attracting much attention recently due to potential applications such as backlights in liquid crystal displays (LCDs) or other illumination purposes. In order for the white OLEDs to be used as backlights in LCDs, the light emission should be bright and have Commission Internationale d'Eclairage (CIE) chromaticity coordinates of (0.33, 0.33). For obtaining white emission from OLEDs, different colours should be mixed with proper balances even though there are a few different methods for mixing colors. In this study, we will report a white organic electroluminescent device using exciton diffusion length concept.

In this paper, we propose impr oved binary tree vector quantization based on spatial sensitivity which is one of the human visual properties. We combine the weights based on spatial masking effect according to changes of three primary colors in blocks of images with the process of splitting nodes using eigenvector in binary tree vector quantization. The test results show that the proposed method generates the quantized images with fine color and performs better than the conventional method in terms of clustering the similar regions. Also the proposed method can get the better result in subjective qualify test and PSNR.
