Various studies with regard to increasing the optical efficiency of plasmonic color filters have previously been conducted, such as mixing materials or applying diverse pattern shapes. Fundamentally, it is important to maximize the photonic crystal effect by finding the optimum periods of lattice as well as calculating the most efficient transmission area. In this study, we propose a technical method for optimizing the plasmonic color filters that have a high color gamut and luminance by analyzing the light spectrums based on the 1931 color coordinate system. Moreover, we suggest a calculation method in order to define the individual color purity of red and green and blue filters. Consequently, efficiency values are obtained independently from each color filter by evaluating the color purity and the luminance. The final result obtained from simulation are 27.6% of relative luminance and 25.3% of color gamut. The proposed optimization method is applicable to all plasmonic color filters having photonic crystal arrays.

This is a study on the status of color scheme of domestic office furniture. In order to pursue the planned and effective usage of color on office furniture, we investigate and analyze the status of used color based on products from four domestic office furniture companies. Once we review the definition and characteristics of office furniture, we theoretically investigate the importance of correct color planning and psychological effect based on the psychological theory as research methods. In addition, objective condition of color analysis is presented by clearly stating the color measurement which is used in this study and the NCS as analysis standards, and status of the usage of color is investigated and analyzed based on representative products from four domestic office furniture companies. Results showed that only five products which are 26.3% out of 19 products from four companies achieved a good balance based on both color harmony theories. We hope that studies to recognize the importance of usage of correct color on the office furniture, to improve the office environment and to increase the efficiency of work will be conducted continuously.

문과 스펜서의 색채 조화론은 먼셀의 색채 조화론을 바탕으로 한 이론이다. 이 조화론은 크게 조화와 부조화, 조화의 면적 효과, 그리고 조화화 부조화의 미도 계산의 3개로 성립된다. 여기서 미도는 조화의 정도를 정량적인 수식으로 구하고자 하는 방법이다. 미국의 학자 버크호프가 문 스펜서의 미는 복잡성 속의 질서성을 가진 것이라는 명제를 분석하였다. 본 논문에서는 배색의 좋고 나쁨은 질서의 요소와 복잡함의 요소로 나누었다. 미도는 질서의 요소를 복잡함의 요소로 나눈 것이다. 이를 영상의 미도 계산에 활용하여, 감성으로 취급되는 색채조화 및 부조화의 문제를 수치적으로 계산하였다. 그리하여 영상에서 색을 판별하여 미도가 좋은 배색인지 아닌지를 나타내었다.

The purpose of this study was to examine improvements in dye uptake, expression of various colors, and color fastness when washed or exposed to light. We examined these improvements by doing the combination dyeing of Juniperus chinensis heartwood and Alnus japonica heartwood extracts. In this study, two combination dyeing methods were used. One-bath dyeing involves combining Juniperus chinensis heartwood extract and Alnus japonica heartwood extract. Two-bath dyeing involves dyeing by sequence, which means that we dyed the Juniperus chinensis heartwood extract first and then dyed Alnus japonica heartwood extract sequentially (or in the opposite order). In terms of improving dye uptake, two-bath dyeing was more effective than one-bath dyeing. For cotton, dyeing Juniperus chinensis heartwood extract first and then dyeing Alnus japonica heartwood extract sequentially showed higher dye uptake in the two-bath method, while for silk, there wasn't much difference in the dyeing order. Through combination dyeing, red-violet color from Juniperus chinensis heartwood and brown color from Alnus japonica heartwood made various Y, YR, R series of color as a result. Moreover, combination dyeing improved fabric's fastness when washed or exposed to light. In the case of cotton, fabric dyed using two-bath dyeing, with Juniperus chinensis heartwood extract being the first dye, showed improvement in fastness to washing and light. And in the case of silk, fastness to washing and light improved regardless of dyeing order in two-bath dyeing.

The purpose of this study is to find out the effect of suit color, necktie color and necktie patterns on the men's suit image formation. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 28 color pictures manipulated with suit color, necktie color and necktie patterns by computer drawing. The experimental design consists of 3 factorial design; 1) suit color (navy blue, beige), 2) necktie color (analogous, complimentary color), 3) necktie patterns (plain, dot, stripe, check, paisley, floral, abstract) The 7-point semantic differential response scale designed for visual evaluation of men's suit image on suit color, necktie color and necktie patterns were composed of 34 bipolar adjectives. The subject are 150 female undergraduate students in Chin-ju city. They responded twice to 14 stimuli at random order The result of this study are as follows; 1. By analyzing the responses of the subjects, 4 factors emerged in the dimensional structure of the men's suit image formed by suit color, necktie color and necktie patterns. The 4 factors are charm, potency, uniqueness and tenderness. Among these, charming and potential factors proved to be more important. 2. necktie color, suit color and neckite patterns had the significant effect on the formation of men's suit image. In the charm image, only necktie patterns were proved to be the most dominant variable. The most dominant variable in the potencial and unique image was necktie color and second to it suit color was important. But suit color was most significant in the image of tenderness. 3. In the effects of interactions between each variables, the combination of suit color and necktie color wins more significant than that of suit color and necktie patterns and that of necktie color and necktie patterns, but in the image of tenderness, only the combination of suit color and necktie color was more significant. In the interaction of suit color, necktie color and necktie patterns, the potential factor didn't have the significant effect.

Cotton and silk fabrics dyed with brazilein(Caesalpinia Sappan), berberine (Phellodendron Amurense), and shikonin(Lithospermum Erythrorhizon) were stored in the air, in the water, and under the ground for about one year. The change of the color, the flexibility, and the breaking strength were measured at the intervals of few weeks. The results are as follows; 1. The color of the fabrics changed most extensively in the fabrics that were under the ground, then in the order of the ones that were in the water, and in the air. The color of the fabrics changed to the achromatic color over the time. 2. The flexibility change among the dyes was similar. All the fabrics became stiff under the ground and in the water over the storage time. 3. In general, cotton and silk fabrics dyed with berberine showed better strength retention than the fabrics dyed with other substances. 4. The strength retention of cotton fabrics was high in the order of the fabrics which were in the air, in the water, and under the ground. Only minuscule change occurred in the strength of the cotton fabrics. The strength of the fabrics that were in the water and under the ground decreased remarkably after 30 weeks and 20 weeks respectively. 5. The strength retention of silk fabrics was high in the order of the fabrics which were in the air, under the ground, and in the water. In the air, the strength on silk fabrics decreased rapidly after 30 weeks. In the water, the strength of silk fabrics decreased more rapidly than that of the cotton fabrics. Under the ground, the strength retention of silk was higher than that of cotton.

Recent beauty trends focus on suitability to individual features. A personal color system is a recent aesthetic concept that influences color make up and coordination. However, a personal color concept has several weaknesses. For example, type classification is qualitative and not quantitative because its measuring system is a sensory test with no industry standard of personal color system. A quantitative personal color type classification model is the purpose of this study, which can be a solution to above problems. This model is a kind of mapping system in a 3D Cartesian coordinate system which has own axes, Value, Saturation, and Yellowness. The cheek color of the individual sample is also independent variable and personal color type is a dependent variable. In order to construct the model, this study conducted a colorimetric survey on a 993 sampling frequency of Korean women in their 20s and 30s. The significance of this study is as follows. First, through this study, personal color system is established on quantitative color space; in addition, the model has flexibility and scalability because it consisted of independent axis that allows for the inclusion of any other critical variable in the form of variable axis.
