After the "Landscaping Law" was enacted in 2007 Korea, national and local governments has been responding swiftly by seeking various methods. Seoul Metropolitan City and other municipalities have established "Seoul Coloring and Systematization" project, which analyzes and extracts the humanities, humanities and natural environments in 2007 as an opportunity to recognize the importance of environmental color. However, it is necessary to slightly supplement the color scheme created by the observer's concept. In this way, you have to find the color of the environment in a city where real life takes place. The city's environmental color has the concept of "walking" as the basic human behavior. Because the average speed is 4km, it differs from that of a vehicle that travels more than 60km per hour. Also, most of the frontage zone is used except for special cases. Therefore the characteristics of the environmental color and frontage zone on the road side were concluded in this paper as Single Type, Connection Type, and Extension Type. In addition, the principle of environmental color of city was established by the change of texture according to space of time and the characteristics of urban scale, and new media characteristics were found in various interactions. The results of this study suggest an environmental coloring strategy for workability such as hue continuity, hue harmonization and integrated design.

This study examined types and color conditions of street views through relationship of high-storied apartment house to street components which has great visual influence on urban street view and requires harmony with street environment as background factor and conducted positive experiment with high-storied apartment houses located at housing site development districts in Gwangju Metropolitan City since 1990s in order to set applicable color ranges in designing external colors of high-storied apartment houses which became background of street view by types. Consequently, in image changes of four factors of main colors in classified street types, P, RP, R and YR colors showed high average values in naturalness, harmony and unity and GY, G, BG and B colors showed dichotomy with low average value, but image of personality showed generally low average value. RP, R and YR colors showed higher adaptability and GY, G and BG colors showed lower adaptability. It was confirmed that according to adaptability of main colors used in high-storied apartment houses by street types, there was difference of appropriate color range in street components and external colors of high-storied apartment houses by street types.

위성화상 또는 항공사진을 이용하여 산화지를 탐지하고 정량화하기 위한 여러 가지 방법적인 시도가 있었다. 보다 정확한 산화지 탐지를 위해, 본 연구에서는 기존의 고해상도 범색화상과 중 저해상도 다중분광 화상의 융합(fusion)에 주로 이용되었던 IHS(Intensity, Hue, Saturation) 색채변환을 산화지 탐지와 정량화에 적용하였다. IHS 색채변환을 이용한 Hue 조합화상의 산화지 최대우도분류 결과는 Landsat-7 ETM+ 7:4:1 조합화상보다 놀은 사용자분류 정확도를 나타냈으며 색상(Hue)과 채도(Saturation)가 명도(Intensity)에 비해 ETM+ 화상의 분광특성을 잘 반영하였다.

In this study, convergence art education which Based on the overall understanding of color, which is a field of science, the lecture model was constructed in order to operate a fusion curriculum which can be practically expressed by applying it to the artistic field of floral design. The learner was satisfied with the composition of the two lectures (floral design, color) and the way of conducting theory and practice. In addition, they felt that was able to access various areas through one subject. This indicates that learners themselves perceive the purpose and necessity of this study. On the other hand, it is pointed out that the background knowledge level between the majors and the non - majors is different. therefore Continuous feedback and adjustment of the degree of difficulty of the training seems to be necessary to enhance the learner's understanding. In order to develop the floral design, the curriculum development and education model should be built through convergence of various sciences. It is expected that this study will be used as basic data for the development of the curriculum for the artistic design education.

LED technology offers versatile lighting control while having a very low environmental impact. Consequently, increasing attention is being paid to the emotional impact of LED lighting. This study investigated whether the chromacity of LED lighting influences people's time perception. To this end, two empirical studies were conducted: First, in experiment I(N=28), the subjects compared their perception of the time duration, which was varied from 3s to 20s, for 6 chromatically nuanced lighting conditions, respectively, with that under a daylight condition. The results showed that, in warm-color nuanced lighting conditions, the subjects perceived time to pass more slowly than in the daylight condition. On the contrary, in cool-color nuanced lighting conditions, the subjects perceived time to pass more rapidly than in the daylight condition. Then, in experiment II(N=39), the subjects were asked to count for 90 seconds while simultaneously performing some cognitive tasks. Confirming the results found in experiment I, the subjects perceived time to pass more rapidly in cool-color nuanced lighting conditions than in warm-color nuanced lighting conditions, although the difference was not statistically significant(p>0.05). In addition, the subjects tended to perceive the time to be shorter when the nuanced color of the light was closer to their preferred color.

South Korea is an aging society with 10.9 percent of its population over 65 years of age, and the aging population naturally leads to a surge in elderly care costs. Compared to general hospitals and other hospitals that have systematic management strategies in an environment of intensifying hospital competition, the design and management strategies of nursing hospitals are insufficient due to the hospital's characteristics of long-term hospital admission and treatment. In this study, We conducted a symbol mark color and form analysis of nursing hospitals to establish a design strategy to meet the increasing demand on nursing hospitals. The subjects of the study were 131 hospitals that received the first grade of nursing hospitals in Korea, and each symbol mark was collected to analyze its form and color. Analysis of the form of symbol revealed that the most anthropogenic symbols were made with artificial objects, and among them, the number of symbols with crosses, hearts and human forms were higher. The color analysis showed that more than 50% of symbols consisted of two colors and the main colors were blue and green. It is expected that this research data will be used as a reference in the design of the symbolism of nursing hospitals, which will help consumers choose and develop strategies for hospital management in order to compete with the ever-increasing demand of nursing hospitals and hospital competition.

Color is a sense signal for human to perceive being through light, and the color is divided into chromatic color and achromatic color. Chromatic color has hue, intensity, and saturation, but achromatic color has only intensity among the properties of chromatic color and doesn't have hue and saturation. Therefore it is important to split colors of image into area for human to perceive colors and not to perceive ones based on vision of human being. In this paper, we find a function to split colors of image into chromatic region of chromatic color region and achromatic region of achromatic color region. First, the input image of RGB color space is converted into the image of HSI color space in consideration of human vision and get a binary image from the converted image. After then, a function to split colors into ROC(ROC: Region of chromatic.) and ROA(ROA:Region of achromatic) is yield. It is difficult to split color of a general image into ROC and ROA. Therefore, to get the chromatic area and achromatic area, we make gradient images to have all range of intensity and range of saturation and to have a little range of hue and yield the function. The evaluation is tested using subjective-quality by 50 non-experts for result images of test images and general images. The results of the proposed method get better 27.5~32.96% than these of the conventional method

Cityschumers experience the urban with the visual perception while walking an average speed of 4km per hour. At this time, recognition of the color field accounts for more than 70%. Therefore, in this paper the environmental color of urban street is examined by dividing the pedestrian visual field area. In the urban street, the area of the visual field area of the pedestrian is divided into Ground Plane, Roadside, Canopy and Building Wall. In addition, we observe and color survey the environmental color of Exhibition Road, which is the northern side space of South Kensington in London, which adopted the world's first shared space. The color of the visual filed area was dominated as YR, GY, Y, PB. The Ground Pland was dominated by the YR. The reason for this is that the color of the floor has changed due to the shadows of surrounding architecture and facilities. Roadside was dominated in various ways such as GY, BG, PB, B and P. Canopy was mainly composed of PB, GY, etc. It was found that the material color of the lower part of the architecture was reflected. The architecture wall was affected by the reflectance and absorption rate of the transparent material. The first image that comes to mind when thinking about the urban is the street where pedestrians walk, feel and enjoy themselves. Therefore, it is suggested that various policy frameworks for managing and managing urban planning professionals may be different from the perceptions of pedestrians active in mega cities.

대중적 건설중장비로서의 유압굴삭기는 1990년대 이후로 탈산업화(post-industrialization)의 영향을 받아, 형태나 색채에 있어서 변화를 시작한다. 이는 일반 소비재 분야에 비하여 다소 늦은 편이라 할 수 있다. 그 이유는 건설중장비 특성상 제한된 사용 충과 사용환경으로 인한 제품개발기간(PDT)과 제품수명주기(PLC)가 길고, 제품개발 비용이 상대적으로 거대하기 때문이다.(중략)

소비자는 상품을 구매하는 데 있어 기능이나 성능이 '우수하다', 값이 '싸다', '비싸다'가 아닌 선호의 관점에서 의사결정을 하고 있다. 소비자의 선호와 취향을 전략화한다는 것은 단순히 무엇을 만들 것인가를 떠나 어떤 이미지론 전달하는 상품을 만들 것인가 혹은 어떤 이미지로 소비자의 감성을 파고들것인가 하는 문제를 바탕으로 하게 된다. (중략)
