Due to the current seriousness of environmental pollution and the eco-friendly movement of the fashion industry, research on sustainable fashion design is being actively conducted. In this study, consumer perception of upcycling products, are divided into image, function, and meaning; and image is further divided into shape, color, and material. It was redefined as pattern, and image recognition was evaluated among men and women in their 20s and 30s, and men and women in their 40s and 50s used as subjects. First, factors that determine each image were extracted based on qualitative analysis of the precedent cases of upcycling bags, and quantitative analysis of the subjects was induced through a questionnaire. As a result of the analysis of evaluation items related to image association, the average frequency analysis of all subjects for each stimuli and the cognitive variance of the frequency analysis by generation by gender were found to be similar. However, awareness of some stimuli by generation showed a significant difference. Overall, in the three stimuli with high overall preference, common features, such as the basic box-shaped symmetrical structure, the monochromatic color of the Munsell system, solid and practical texture, and appropriate use of patterns were identified. In addition, it was confirmed that there was a difference with factors such as femininity, simplicity, touch, and splendor in the measurement factors. In conclusion, it is considered that the main significance of this study is that it excluded the recognition and meaning of upcycling products and explored the original design and image elements of products. Therefore, it is expected that this study will be used as a basic data for responding to the gender image of each generation as an alternative method of sustainable fashion design, and it will be an opportunity to expand the scope of the study to a detailed study beyond the biased topic.

Nitrogen fertilization and cutting practice were studied on turfgrasses and cover plants to investigate the possibility of maintaining green color during the growing season. Research also involved the effect of the nitrogen on a few morphological characteristics of leaf performance elements which might give an information to coloration and life-span of turf leaves. Treatments in the first experiment undertaken on pot included one N level: 350kgN /ha applied as compound fertilizer in split applications of one-half in mid-May and the rest both in late June and August, and four spring-summer cuts: late May, late June, late July and late August. The soil filled in pot a moderately well-drained sandy loam. In the second experiment(field observation) leaf length and width, inflorescence and flowering, and color performance were also investigated. With nitrogen fertilizer applied on turfs, desirable turf color was maintained during a period of poor coloration in specific seasons such as mid-summer for cool season grasses and late fall for warm season grasses comparing to the non-treatment. However, this was not stimulated by cutting treatment to nitrogen status existed. Cutting effect on coloration was more remarkable in both Korean lawngrass and Manilagrass than in cool season turfgrasses such as Italian rye-grass, perennial ryegrass and tall fescue. Especially down-slide of leaf color in cool season turfgrasses could he detected in mid-summer /early fall season ranging up to mid-September. In early November as well as mid-September, Italian ryegrass, perennial ryegrass and tall fes-cue retained a high level of green color as followed by nitrogen application and cutting treatment, and little detectable variation of leaf color notation between cool season turfgrasses was obtained. However, Korean la'vngrass and Manilagrass failed to retain the green color until early November. Color notations in cool season turfgrasses investigated early November on the final date of the experiment ranged from 5 GY 3/1 to 4/8 in 'Ramultra' Italian ryegrass, 'Reveile' perennial ryegrass and 'Arid' tall fescue, but those in Zoysiagrasses were 7.5 YR 4/8 in Korean lawngrass and 2.5 y 5 /6 in Manilagrass. Life-span of leaves was shorter in Italian ryegrass, perennial ryegrass and tall fescue than in beth Korean lawngrass and Manilagrass with and without nitrogen application. In general, leaves appeared in early May had a long life-span than those appeared in late April or mid-June. Nitrogen application significantly prolonged the green color retaining period in perennial ryegrass, Italian ryegrass, Korean lawngrass and Manilagrass, and this was contrasted with the fact that there was no prolonged life-span of leaves emerging in early May and mid-June in tall fescue. SPAD reading values in 48 turfs and cover plants investigated in the field trial were increasing until late June and again decreasing till September. Increasing trends of reading value could be observed in the middle of October in most of grasses. On the other hand, clovers and reed canarygrasses did not restore their color values even in October. Color differences between inter-varieties, and inter-species occurred during the growing season under the field condition implicated that selection of species and /or cultivars for mixture should be taken into consideration. In Munsell color notation investigated in the final date in the middle of November, 32 cultivars belonged under the category of 5 GY and 10 cultivars under the category of 7.5 GY. This was implying that most of cool season turfs and cover plants grown in the center zone of Korean Peninsula which are able to utilize for landscape use can bear their reasonable green color by early or mid-November when properly managed. The applicable possibilities of SPAD readings and Munsell color notation to determine the color status of turfgrasses and cover plants used in this study were discussed.

The purpose of this study is to provide basic information to improve competitiveness of Korean fashion brands in the Chinese fashion market by taking photos of street styles in Seoul that is the hub of Korean fashion and in Dalian, the northeastern district where Korean fashion brands are launched as a test market China to compare and analyze the clothing colors preferred mostly by young women in their twenties and thirties who have the highest purchasing power. The study methods used literature review and empirical study simultaneously. Dalian and Seoul are two fashion cities in northeast of China and Korea where street fashion was photographed. Clothing colors that were mainly worn by young women in their twenties and thirties were qualitatively analyzed using the photos taken. Color analysis was based on the Munsell Color Order System to grasp general preferences of colors on the basis of previous researches, and color tones were based on the ISCC-NBS System. In order to grasp the basic materials on Seoul, the Korean fashion city and Dalian, the northeastern fashion city in China, street fashion styles of 2010/11 F/W season were compared and analyzed. As a result, black and deep tone PB color appeared most frequently. The vivid and strong tone of R, YR, Y color showed high frequency of clothing colors. For the top wear, women in both areas preferred similar tones in the YR color category and Dalian women preferred vivider and brighter S tones in the R color category. For the bottom wear, women in both areas highly preferred achromatic colors and colors in the PB color category. For bags, women in both areas preferred black and colors in the YR color category. Finally, for the shoes, while women in both areas preferred black in the achromatic color category, they showed different color preferences in the chromatic color category. R color categories were preferred by the women in Seoul and the YR color categories were preferred by the women in Dalian. Conclusively, women in both cities highly preferred achromatic colors especially black for the top and bottom wear, bags, and shoes. It may reflect their desire to look refined and slender through colors. Moreover, continuous and steady research on fashion trends in Seoul and Dalian may have positive effects on Korean fashion businesses that plan to be launched in China, the area of competition for global brands.

The textile industry is petting increased effort to manufacture the value-added products that gives the differentiated characters at every level of fiber and fabric production. The color is an important element to be used strategically in order to push up the value-added design. The colors of apparel products have a close relationship with the skin colors of consumers and their preference colors. This study was carried out to cluster the skin colors of the Korean women into several similar skin colors and to analyze their preference colors by the classified groups. We measured the skin colors of 354 Korean women. With color spectrometer, JX-777, we measured 4 points of the body; cheek with removing cosmetics off, forehead, rear neck and arm on the interior part near elbow. All subjects had been shown with 40 color chips and answered the preference colors and preference colors of apparel. Data were analysed to classify skin colors using K-means Cluster Analysis and Duncan test, Frequency and Chi square test on the preference colors about the clustered 3 groups. In doing so, we used in SPSS Win 10 statistical package. Findings were as fellows: 1) The skin colors of the Korean women were clustered into YR, R, and Y skin colors. The majority of the subjects, 324 observations had YR skin colors and the subjects were classified into 3 kinds of skin color groups who had YR skin colors. 2) The average skin colors of total 324 subjects was 5.23YR 6.49/4.09 in Munsell Color System(MCS), 66.56 in L value, 10.53 in a value, and 20.67 in b value. 3) The average skin color of Type 1 was 7.98YR 6.24/4.14 in MCS, 64.10 in L value, 15.05 in a value, and 24.0 in b value. For Type 2 was 7.30 YR 6.56/3.28 in MCS, 67.24 in L value, 6.89 in a value, and 18.4 in b value, and Type 3 was 7.01 YR 7.20/4.38 in MCS, 73.53 in L value, L 16.04 in a value, and 24.87 in b value. 4) The average face color of total 324 subjects was 7.31YR 6.65/3.56 in MCS, 68.13 in L value, 9.53 in a value, and 20.18 in b value. 5) The average face color of Type 1 was 4.19 YR 6.92/5.05 in MCS, 70.78 in L value, 13.2 in a value, and 25.32 in b value. For Type 2 was 5.24YR 6.33/3.79 in MCS, 64.94 in L value, 9.84 in a value, and 19.08 in b value. Type 3 was 5.4YR 6.85/4.68 in MCS, 70.1 in L value, 11.73 in a value, and 23.92 in b value. 6) The difference of mean values between the clustered 3 skin color groups showed significantly different except the a value of neck and H value of cheeks and H value of foreheads. 7) All 3 groups showed that the most preference colors and the most preference colors of apparel was 5R 4/14. and their preference colors were much more than the preference colors of apparel.

As information-communication network has been developed rapidly, internet users' circumstances also have been changed for the better, in result, more information can be applied than before. At this moment, there are many differences between real color and reappeared color on the CRT. When we observe a material object, our eyes perceive the multiplied form of light sources and nature spectral reflection. However, when the photographed signal is reappeared, illumination at that time of photographing and spectral reflection of a material object are converted into signal, and this converted RGB signal is observed on the CRT under another illumination. At this time, RGB signal is the reflected result of illumination at that time of photographing Therefore, this signal is influenced by the illumination at present, so it can be perceived another color. To accord the colro reflections of another color source, the study has been reported by S.C.Ahn$^{[1]}$, which study is about the color reapperarance system using neuron network. Furthermore, color reappearing method become independent of its circumstances has been reported by Y.Miyake$^{[2]}$. This method can make the same illuminations even if the observe circumstances are changed. To assume the light sources of observe circumstances, the study about color reappearing system using CCD sensor also have been studied by S.C.Ahn$^{[3]}$. In these studies, a population is fixed, first, on ab coordinates of CIE L${\ast}$a${\ast}$b${\ast}$. Then, color reappearing can be possible using every population and existing digital camera. However, the color is changed curvedly, not straightly, according to value's changes on the ab coordinates of CIE L${\ast}$a${\ast}$b. To solve these problems in this study, first of all, Labeling techniques are introduced. Next, basis color-it is based on Munsell color system-is divided into 10 color fields. And then, 4 special color- skin color, grass color, sky color, and gray-are added to the basis color. Finally, 14 color fields are fixed. After analyzing of the principle elements of new-defined-color fields' population, utility value and propriety value are going to be examined in 3-Band system from now on.

교통사고의 주된 원인은 자동차 주행 중 운전자의 시각적 주의 분산이다. 본 연구에서는 운전자의 시선을 도로에서 벗어나지 않게 하면서 주행정보를 제공하는 HUD(Head Up Display)시스템을 이용해서 자동차 앞 유리(windshield)에 투영된 주행정보의 색채감성을 평가하였다. 주행정보는 전방시선 $0^{\circ}$에서 약 하방 $9^{\circ}$에 위치하도록 설치하였고, 실험실의 형광등, 5개의 LED 조명등과 TV출력 영상을 통해 25[lux]의 야간 운전 시 조도 환경, 100,000[lux]의 주간 운전 시 조도 환경을 재현하였다. 먼셀 표색계의 기본 5색(R, Y, G, B, P)과 신호등의 색 YR, W 총 7색의 단일 색과 W를 제외한 6개 글자에 각각 흰색 글자 외곽선, 회색 글자 외곽선을 주어 외곽선 있는 글자 12개를 만들었다. 총 19개의 실험 자극물을 주간과 야간 환경에서 각각 주행정보의 컬러 시인성, 피로도, 선호도, 방해 정도를 평가하였다. 실험결과는 시인성이 유의미하게 나왔는데, 첫째, 주간에서는 Y와 G 색상같이 색상 자체의 휘도가 높은 경우 시인성이 높았다. 둘째, 텍스트의 외곽선이 있는 경우, 외곽선이 배경색으로 작용하여 색상과의 휘도대비를 일으켜 시인성에 영향을 준다. 셋째, 외곽선이 없는 경우에는 차량 전면 유리의 휘도가 배경색 휘도로 작용하여 글자의 휘도와 큰 대비를 이룰 때 시인성이 높은 것으로 나타났다. 이처럼 운전자의 주시야를 고려해 전방에 제공되는 가상의 영상, HUD의 상용화를 위해서는 주행정보의 색채시인성이 중요한데 이를 높이기 위한 방안으로 배경과 글자의 휘도대비를 고려해볼 수 있다.

The purpose of this study is to provide the basic information necessary to develop sports uniform design by comparing and analyzing the color features and images of professional football uniforms in Korea and foreign countries. The subjects of this study were limited to 5 top leagues in Europe (Premier League, Primera Liga, Bundesliga, Serie A, and Ligue 1) as well as J-League, and K-League. This study was done using the 2012/2013 season home and away uniforms for European leagues and 2013 season home and away uniforms for Korean and Japan leagues. Using the Adobe photoshop CS2 eyedropper tool, color chips and RGB values were extracted from digital images and converted into HV/C of Munsell Conversion. Finally, a total of 735 colors were used for the analysis. The color image scale by Shigenobu Kobayashi was used to position the color images. The results are as follows. First, the color analysis of professional football uniforms in leagues suggested that chromatic color (53.7%) was more prevalent than achromatic color (46.3%). The two most common colors of the ten chromatic colors were R(19.7%) and PB(18.0%), followed by Y(5.4%), RP(2.0%), G(1.9), GY(1.8%), B(1.6%), YR(1.5%), P(1.1%), and BG(0.7%). Second, for the color tone comparison and analysis of professional football uniforms in leagues, the most commonly used color tone was W(28.4%), followed by v(25.5%), Bk(16.3%), s(5.8%), dk(5.2%), b/lt(5.2%), dp(3.0%), sf(2.0%), ltGy(1.0%), p(0.5%), G/dkGy(0.4%), and ltg/mGy (0.1%). Third, for the comparison and analysis of color and color tone of professional football uniforms in leagues, W(28.4%), R(v)(17.7%), and Bk(16.3%) were commonly used. Finally, for the comparison and analysis of color images of professional football uniforms in leagues, the most commonly used color image was a casual image(31.8%), followed by modern image(26.5%), dynamic12.8%), cool casual(12.0%), gorgeous(9.3%), clear(6.6%), chic(3.5%), and elegant images. Dandy, classical, romantic and pretty images(0.4% respectively) were also used.
