Next generation displays show a trend of evolving from the display device environment (represented by existing televisions) to the mobile environment. The mobile display corresponding to the personal display is similar to a home theatre; however, they are advantageous because they are small and have a relatively lower weight. Therefore, the display industry has an interest in diverse product applications of displays, reproducing more accurate colours, and offering improved image quality from display devices of various sizes. To address these interests, a psychophysical experiment was conducted in this research. The experiment compared the size of the colour stimulation corresponding to foveal vision by gradually increasing the lightness of the background. This was based on the assumption of possible differences in colours being recognized by the lightness of the background and the size of the colour stimulation. Contrary to the results of previous studies, where the colours are identified more clearly as the size of the colour stimulation increases (assuming that the lightness of the background is not considered) here the results of the experiment showed that the attributes of the identified colours were different depending on the lightness of the background and the size of the colour stimulation. Based on the experimental results, it is possible to resolve errors in colour conversion that can occur when the input image is switched from a large screen size to a mobile size display, and to reproduce the colours more accurately and improve the image quality.

Originally the COS system was developed based on fashion colors. But in interiors many other color groups are used frequently, so the COS system is somewhat insufficient for interior design work. The purpose of this study is to verify the pratical use of the COS system in finishing colors of housing interiors and to propose the additional colors based on interior finishings. The COS system and the NCS color system were used for color measurement. The results was as follows. In the hues, Y.YR.GY.PB.B.BG color groups were used for interior material more frequently. And regardless of hues, low saturation and high value colors were used. Most of the colors were inscribed as the COS system and the NCS color system simultaneouly, but muted and grayed color tones like pale.light.grayish.soft cannot be founded in the COS system. Therefore more subdued and soothing tones of Y.YR.GY.PB.B.BG color groups should be added to the COS system.

This study suggests story telling-based scenery color plan that uses local story resource in order to raise possibility of success in making characterized town implemented by Ulju-gun, Ulsan Metropolitan City. Characterized town making project of Eoeumhari Town is the first in Ulsan, and detailed project planning is going underway to transform it into story telling street by providing local story to the resource of Eoeumhari Town. Ulju-gun expects big help in luring tourists and activating local economy by maintaining these towns. As in this way, local marketing that uses story telling is recently being taken as a desirable way of overcoming the limit of local development, and it suggest new possibility of scenery color plan. Therefore, I attempted to extract Brand Story from story resources based on climatic color of Eoeumhari Town and apply them to the color plan in order to unique color identity with a town as a unit. It is significant to study as it suggests a direction to discover values of color which can be used for establishing local identity and activating local community breaking from current color plan by large-scale maintenance implemented by each local government.

In this paper we propose symbol decision method reflecting the color non-uniformity in 3-dimensional color space. By comparing with 2-dimensional color space decision method, we show the superiority of BER performance of the proposed method. Proposed method may reflect the non-uniformity since the symbol decision boundary in color space is transformed from 3D RGB space, and one dimension corresponding to Y value is added. Therefore, we can obtain the better BER performance by using the symbol decision method in 3D color space. In this paper, through numerical simulation, show the superior BER performance of 3D color space symbol decision method compared with 2D color space symbol decision method under AWGN and common mode noise channel.

본 연구의 목적은 한국의 전통음식 중의 하나인 비빔밥의 재료들의 색채 범위를 분석하여 메뉴북에 인쇄되어지는 재료별 색채범위를 제시하고자 하였다. 본 연구의 목적을 달성하기 위하여 다음과 같은 과정을 통해 진행하였다. 먼저 한국의 전통음식에 근거한 비빔밥 사진과 레시피를 확정하였으며, 요리 전문 사진가를 통해 메뉴북에 가장 보기 좋게 인쇄되어질 수 있는 촬영 기준을 선정하였고, 위의 환경에서 비빔밥 사진을 촬영하였다. 세부적으로 3회 정도의 사진 촬영을 한 후 가장 좋은 상태의 사진을 선정하여 이 때 각 재료들의 색채 값을 측정하였다. 색채 범위 측정을 위해서 Lab 값과 CMYK 값을 적용하였는데, Lab 값은 밝기, 붉은색, 황색을 측정하는 값으로 육안으로 표현되어지는 색이며, CMYK 값은 메뉴 북에 인쇄되어지는 색의 값을 의미한다. 본 연구의 결과, 육안으로 보여지는 색깔과 메뉴북에 인쇄되어지는 값이 다르게 보여진다는 결과를 보였다. 최적 상태 각 재료별 인쇄 값은 다음과 같다. 청포묵은 C23 M5 Y8 K0였고, 호박은 C75 M24 Y100 K9였으며, 고사리 C64 M55 Y76 K55였다. 콩나물은 C38 M24 Y55 K1였고, 당근은 C12 M75 Y87 K2였으며, 표고버섯은 C45 M37 Y78 K11였다, 시금치는 C82 M44 Y100 K48였으며, 도라지는 C25 M5 Y24 K0였고, 계란은 C26 M19 Y100 K0였으며, 마지막으로 쇠고기는 C66 M5 Y72 K0였다.

This study examined whether the combination of the indoor temperature on the learning environment and the colors of the learning materials affect the learning performance. To do this, the condition of indoor temperature was divided into three conditions: the neutral condition which is the appropriate temperature condition of the learning activities ($22.5{\sim}24^{\circ}C$), the high-temperature condition (> $24^{\circ}C$), and the low-temperature condition (< $22.5^{\circ}C$). In addition, colors of red, blue, black, and green were used as the warm, cold, and neutral colors, and the verbal-working memory task was used as the learning task. As a result, it was not significant differences in the response time of the learning task, whereas, in the accuracy rate of the learning task, the performance was more accurate in red- and black-color conditions. These results could be interpreted as the saliency and color-temperature of the red color, and the familiarity and specificity of the black color.

In this paper, we study the bus stop shelters, one of the public facilities, revised by the development plan of Seoul city. Dark gray and brown are dominant colours for the shelters. As representative colours, designated by Seoul city, dark gray and brown can be harmonious naturally with urban environment. However, in view of universal design, those colours have some problems to be recognized and to be used for handicapped groups, olds and childens especially. For analysis, investigating proposition and circumstance of two groups living in the city is the first place. This study is for building proper colour domains of universal design for public facilities and for recognizing that the way of public facilities should be that the ambit of public space is not regarded as a facility but recognized easily in accordance with environment including a facility. we hope that this paper is practically used as a reference for coming studies are the purposes of this study.

Color can stir up the feeling and the thinking of the human inside, and heals human's illness. The color of architecture is a systematic physical space of shape and color. In other words, color is a kind of visual language organizing a structure and interact with human. The color of hospital can be specially effective to heal the elderly. This study intends to help geriatric hospital in future to elevate remedial value and indicate basic data for adapted the elderly environment. NCS is a kind of color system based on the human psychology and nature. This study researched the color of geriatric hospital with NCS and annualized the color nuance of each spaces. As a result the distribution of color nuance show the present of the geriatric hospital's color planning.

항만은 해륙교통의 요충지로서 그리고 국토의 균형적인 발전과 지역진흥의 기반으로서 중요한 역할을 담당하고 있지만 노후항만시설 및 쇠퇴공간에 대한 유지 및 보수가 효과적으로 이루어지지 않아 기능의 상실은 물론 재해와 우범화의 대상이 될 수 있다. 특히, 항만의 활성화를 위해 중요한 부분인 항만고유의 기능인 생산 및 물류의 지원과 아울러 소득수준 향상에 따른 풍부한 생활공간으로의 환경 친화적인 정비와 항만재개발이 필요하며, 미래지향적 종합항만공간으로의 기능전환이 이루어지고 있다. 국내 최초로 대규모 항만재개발이 추진되고 있는 부산북항재개발 사업에서도 항만도시의 경쟁력을 위해 국가차원에서의 경관계획을 반영하고 있으며, 해양도시 이미지 개선 및 가치향상을 위한 노력의 일환으로 고유의 자연, 역사, 문화적 자원과 함께 각종시설, 건축물, 상징물, 생태 녹지의 상황과 특성에 맞는 경관조성에 노력을 하고 있다. 본 연구에서는 부산북항재개발 사업에 대한 경관색채계획 사례분석을 통해 경관조성방안에 대해 향후발전방향에 대한 기초자료로 활용 할 수 있으리라 판단된다.
