In this study, the effect of clothing color preferences of adolescents on their self expression desires and fashion interest were investigated. These investigations were intended to understand some psychological aspects of adolescents and to make a contribution to guiding them in forming self identities and expressing themselves confidently through clothing. This research was based on 452 copies of questionnaires distributed to middle and high school students living in Seoul and other metropolitan areas from the middle of March to the beginning of April, 2008. The results were as follows. First, there was a significant difference in clothing color preference and clothing color tone preference between male students and female students. Second, the factor analysis which has been performed by taking assimilation, individuality, recognition, and image management as composing dimensions of self expression desire shows significant differences between these dimensions. Third, the difference in the self expression desires according to clothing color preference showed that the group preferring cool colors and the group preferring warm colors possessed the same highest self expression desires. And, it was revealed that the clothing color preference was a significant variable influencing fashion interest. Fourth, the effect of self expression desire on the fashion interest degree showed that recognition was the most significant factor and image management was the next.

하나의 예술 작품에서 표현되는 정서적 분위기에는 그 작품 자체의 구조적 상황을 묘사하여 나타나는 것과 동시에 색채로 표현되는 것이 담겨 있다. 여기서 색채적 특성은 기쁨, 슬픔, 만남, 이별 같은 감성은 물론 구성의 무거움과 가벼움, 느리거나 빠름 등을 그림에 반영한다. 또한 색채표현의 대비, 조화, 색채의 강렬함, 수수함 등의 시각적인 향연을 통해 관찰자의 시선을 끌어들인다. 색채특성의 융합연구는 그림의 절대면적을 차지하는 색역(color gamut, 色域)이 주된 역할을 하고 그 밖의 다른 색들은 이 색역의 조영하에 빛을 발휘하는 것에 관한 연구이다.

This paper provides data for product development and improvement of grape varieties by analyzing the satisfaction-importance of the grape selection attributes from a consumer's perspective. A survey was conducted on consumers aged 19-59 living in Seoul, Gyeonggi and Incheon on their fruit consumption level, preferences according to the grape quality characteristics, importance, and satisfaction with the grape selection attributes. Three hundred and eighty two valid samples were collected and analyzed statistically using SPSS 23. In the preference according to the grape quality characteristics, consumers tended to prefer a sweet taste, black color, and seedless grapes. Regarding the importance of the grape selection attributes according to the level of grape consumption, the high consumption group considers texture, size, shape, color, ease of removing seeds, country of origin, area of production, certification, and brand to be more important. In satisfaction, the high consumption group rated satisfaction highly in texture, odor, size, shape, color, ease of removing peelings, ease of removing seeds, price, country of origin, area of production, certification, and brand. An analysis of the IPA of the grape selection attributes showed that improvement of price and shape attributes will be prioritized, and the development and management of properties, such as seeds, peelings, certification, and brand will be required. These results can be used to help improve the grape varieties and develop products that meet the consumer needs, secure the competitiveness of grape farmers, and revitalize the local economy.

This paper considers a six sigma project for reducing the color variation of the monitor materials in a chemical plant. The project follows a disciplined process of five macro phases: define, measure, analyze, improve, and control (DMAIC). A process map is used to identify process input variables. Three key process input variables are selected by using an input variable evaluation table; a melting pressure, a coloring agent, and a DP color variation. DOE is utilized for finding the optimal process conditions of the three key process input variables. The sigma level of defects rate becomes a 4.58 from a 2.0 at the beginning of the project.

Sulgidduk samples containing control, 0.5, 1, 1.5 and 2% black ginseng extracts and a control were examined for moisture content, color, textural characteristics, and sensory qualities to determine the optimal ratio of black ginseng extracts in the formulation. The moisture content of sulgidduk added with black ginseng extracts was 37~40%. Additionally, the lightness decreased and the redness and the yellowness increased as the black ginseng extracts content increased. Hardness, springiness, gumminess and chewiness increase with the addition of black ginseng extracts. however, adhesiveness did not differ significantly among the groups. Sulgidduk containing 1% black ginseng extracts received the highest scores for color, flavor, texture and overall preference. Based on the above results of sensory and texture analyses, sulgidduk containing 1% black ginseng extracts had the highest quality for commercialization.

In this paper, we propose a new color interpolation method based on trilateral filter approach, which not only preserve the high-frequency components(image edge) while interpolating the missing raw data of color image(bayer data pattern), but also immune to the image noise components and better preserve the detail of the low-frequency components. The method is the trilateral filter approach applying a gradient to the low frequency components of the image signal in order to preserve the high-frequency components and the detail of the low-frequency components through the measure of the freedom of similarity among adjacent pixels. And also we perform Gaussian smoothing to the interpolated image data in order to robust to the noise. In this paper, we compare the conventional demosaicing algorithm and the proposed algorithm using 10 test images in terms of hue MAD, saturation MAD and CPSNR for the objective evaluation, and verify the performance of the proposed algorithm.

The goal of this study was to contemplate the impact of visual formative elements on the satisfaction level of visitors in websites of toy-style products. To attain the goal, the visual element of motion graphics in websites of toy-style products, i. e., color, layout, illustration, and, typography, were independent variables and the satisfaction level of visitors as a dependent variable. The variables were analyzed objectively. First, it appeared that visual formative elements of motion graphics appeared in websites of toy-style products exerted statistically significant impacts on the satisfaction level of visitors. Second, the element exerting the most significant impact on the satisfaction level of visitors among the visual formative elements in websites of toy-style products were appeared as 'illustration' and 'color'. Thus, it was concluded that it is necessary to give priority in 'illustration' and 'color' to enhance the satisfaction level of visitors.

The extraction of attention NPC in a FPS game has emerged as a very significant issue. We propose an efficient FPS game operation method, using the attention NPC extraction with a simple arithmetic. First, we define the NPC, using the color histogram interaction and texture similarity in the block to determine the attention NPC. Next, we use the histogram of movement distribution and frequency of movement of the NPC. Becasue, except for the block boundary according to the texture and to extract only the boundaries of the object block. The edge strength is defined to have high values at the NPC object boundaries, while it is designed to have relatively low values at the NPC texture boundaries or in interior of a region. The region merging method also adopts the color histogram intersection technique in order to use color distribution in each region. Through the experiment, we confirmed that NPC has played a crucial role in the FPS game and as a result it draws more speed and strategic actions in the game.

텍스트 모드에서 흑백 데이터를 컬러 데이터로 변환시킬 때 하드웨어적인 방법을 이용하여 실시간적으로 변환할 수 있는 회로를 설계 및 구현하였다. Color Palette ROM에 화면을 구성하는 모든 페이지에 해당되는 색상 정보를 저장한다. 이 색상 정보는 8비트 단위로 출력이 되며 하위 4비트는 전경색, 상위 4비트는 배경색을 가지도록 지정한다. Address Reduction ROM을 두어 중복되는 어드레스를 배제하여 Color Palette ROM의 용량을 1/16로 감소시킬 수 있도록 하였으며, 다수 개의 D-FF을 두어 어드레스와 데이터 그리고 페이지 정보를 임시로 저장한 후에, Counter를 통해 실시간에 8회의 처리과정을 거친 후 Multiplex에서 전경색과 배경색을 구분하여 컬러 비디오 컨트롤러에 색상 정보를 보내도록 설계하였다. 기존의 흑백 LCD 디스플레이를 사용하고 있는 각종 제어장치 설비를 컬러로 변환함에 있어서 용이한 실시간 인터페이스로 활용될 것이다.

동일한 Display 장치를 인간의 눈으로 봤을 때와 카메라로 봤을 때 표현되는 Color는 너무나 다르다. 인간에게는 광원(光源)의 종류에 따른 색 분광에너지가 달라도, 그 차이를 적게 하는 색순응(Chromatic Adaptation)이라는 능력이 있는데 이것은 카메라에게는 없는 능력이기 때문이다. Display 장치에 어떤 영상신호를 띄우고 카메라로 Display 장치를 촬상했을 때 원본 영상과 카메라로 비춰진 영상의 Color와 계조를 일치시키기 위해서는 Display 장치와 카메라의 색온도를 맞추어야 하는데, 카메라와 Display 간(間) 색온도 차이가 발생한다면 Display 장치의 영상은 의도하지 않은 색으로 표현되어진다. 카메라 색온도는 사용되어지는 조명에 맞추어 조정되며, Display 장치의 색온도를 여기에 일치시키는 방법을 통칭 'CMS(Color Management System) for Display Equipment'라 하고 그 방법을 소개하고자 한다.
