  • Two-color 적외선 탐색기는 표적의 대응 능력과 배경 잡음이 존재하는 상황에서 효율적인 표적 추적을 위해 두 개의 검출 대역을 사용한다. 본 논문은 Two-color 탐색기의 검출 대역 선정에 관한 연구이다. 검출 대역을 선정하기 위해, 표적, 섬광탄, 및 배경 잡음의 적외선 방사 특성을 분석하고, 수신 전력과 깊이 관련된 대기 투가 특성, 검출 가능 거리, 배경 잡음의 영향, 신호 대 잡음비 등의 특성을 분석한다. 분석 결과, two-color 적외선 탐색기의 적절한 대역은 표적 검출을 위한 3$\mu\textrm{m}$~5$\mu\textrm{m}$ 대역과 반대응 능력을 위한 $1.5\mu\textrm{m}$~1.7$\mu\textrm{m}$ 대역으로 나타났다. 본 논문의 연구 결과는 two-color 탐색기의 추후 연구에 중요한 역할을 할 것이다.

  • The property changes of 18, 14, and 8K green gold alloys for jewelry are observed by adding 0.0, 3.0, and 5.0 wt% of indium (In), respectively. To check the composition of the alloys, an energy dispersive spectroscopy (EDS) analysis is conducted. Color and microstructure analysis is executed through bare-eye, macro camera, UV-VIS-NIR-colormeter, and optical microscope. The melting point, wetting angle, and hardness are measured using TGA-DTA, a wetting angle tester, and a Vickers hardness tester. The EDS analysis result demonstrates that each of the green gold alloys was manufactured with purposed contents. The color analysis result shows that the color of the alloys is similar to the color of the conventional 4 wt%-Cd 18K green gold, and the green color improves as the In content increases. The micro structure analysis result demonstrates that grain refinement improves as the amount of In increases. Enhancements in the melting point, wettability, and Vickers hardness changes appear as the In content increases and Au content decreases. The hardness is up to 260, which implies good durability. Therefore, the results suggest that the proposed 18, 14, and 8K In-added green gold alloys enhance the properties of jewelry products with regard to the green color, castability, and durability.

  • 색체이미지의 가치평가를 위한 객관적이고 구체적이며 우리나라 실정을 반영할 수 있는 평가척도의 개발은 색채기획의 중요성과 함께 시급한 문제임에도 아직 활발한 색체기획의 중요성과 함께 시급한 문제임에도 아직 활발한 연구가 이루어지지않고 있다. 따라서 본연구는 색채이미지의 척도 개발을 위한 기초연구로서 선행된 연구들을 수집하여 색채이미지의 개념 및 연구경향과 연구방법론에 대해서 연구대상 및 표집, 자극도구 및 분석방법, 평가척도의 측면에서 종합적으로 분석하였다. 의류상품의 색채기획을 위하여 색채 이미지에 대한 다양한 주제의 연구와 연구대상 선정을 여러계층으로 확대시켜 볼 필요가 있다. 연구내용에 따라 자극도구의 신중한 작성과 적절한 분석방법의 선택이 요구되며, 분석방법은 주로 이미지의 인자를 추출하는 요인분석이 사용되었다.

  • Most important step for the color matching in scanner is the color coordinate transformation from the scanner RGB space to device independent uniform color space. A variety of color calibration technologies have been developed for input device. Linear or nonlinear matrices have been conveniently applied to correct the color filter\`s mismatch with color matching function in scanners. The color matching accuracy is expected to be further improved when the nonlinear matrices are optimized into subdivided smaller color spaces than in single matrix of the entire color space. This article proposed the scanner calibration method using subspace division regression analysis and it were compared with conventional method.

  • The purpose of this research is to analyze the manifestation of children's color education in the software in order to evaluate conditions of color education as well as improvement of its direction. The procedure and method of the research is begun from evaluating the characteristic of children's developmental stage, content analysis of the nation's organization of color education and analysis and evaluation of education program through the investigation on 8 different softwares in reward for the tournament. The results are as followings; First, the research shows that the elementary school stage of color education is inadequate in comparison to children's cognitive developmental stage. Second, most of the color theory was composed of characteristic of a color, stimulation of emotion and effects of psychology. Considering of children's cognitive development, it is necessary to make up for the basic of color theory and the system of color. Third, Softwares of color education program for 1 st. and 2nd grade in elementary school was so rare that it should be properly developed and made for systematic contents. Fourth, color education for the 5th and 6th grade children remained in understanding basic characteristics of the color which is below the par and brings the necessity for more professional and structural contents.

  • 캐릭터(Character)는 풍부한 스토리텔링과 다양한 디자인 요소를 지니고 있다. 국내캐릭터는 오프라인과 SNS를 통해 다양한 형태로 변화 발전하고 있으며 콘텐츠 산업적인 측면에서 발전하고 있다. 본 연구의 목적은 캐릭터 이용자들이 어떠한 스토리텔링 요인과 색채 요인으로 국내 캐릭터들을 이용하고 만족하는지에 대해서 요인을 발견하고 논의하는데 있다. 스토리텔링 측면에서는 모험, 판타지, 황당하고 익살스러운 스토리를 선호하는 것으로 나타났다. 색채 측면에서는 단순하고 심플한 주요색과 난색으로 구성되어 따뜻하고 귀여운 느낌의 색채 구성을 지닌 캐릭터를 선호하는 것으로 나타났다. 반면에 스토리텔링 측면에서는 단순한 소재의 유아 교육, 패션이나 완구가 주목적으로 되어 있는 단순한 스토리를 지닌 캐릭터는 비 선호하는 것으로 나타났다. 색채 측면에서는 주요색이 없이 4개 이상의 색들로 조합이 되어서 복잡한 느낌을 주는 캐릭터를 비 선호하는 것으로 나타났다. 스토리텔링 측면에서는 모험, 판타지 구조를 지닌 스토리 전개를 통해 OSMU의 콘텐츠로 변화 발전시킬 필요가 있다. 색채 측면에서는 이용자들이 선호하는 단순하고 심플한 난색으로 구성할 필요가 있으며 조립 로봇완구 캐릭터도 단순한 색상 구성을 통해 캐릭터의 이용 만족도를 높일 필요가 있다. 본 연구결과 스토리텔링과 색채 측면에서 이용자들이 만족하는 요인을 도출하였으며 이러한 결과들이 이론적 측면, 스토리텔링 측면, 캐릭터 디자인, 산업적인 측면의 발전에 도움이 될 것이다. 위와 같은 논문의 의의에도 불구하고 구체적인 캐릭터 대상의 스토리텔링의 분석틀과 색채분석틀을 통한 연구, 색채분석에 대한 정확한 데이터분석 제시, 캐릭터 하나에 대한 단순 비교 분석을 연구의 한계점으로 지니고 있다.

  • This study was done to define the color range, images and color characteristics of beige in fashion by analyzing the characteristics of beige that appears in contemporary fashion. In reference research, the general characteristics, the color name and range of beige was examined. In investigation research, color characteristics and images of beige that appear in contemporary fashion was defined, and it was discovered that the cases that the use of beige took more than 50% of the entire in the major collection from S/S season in 2007 to F/W season in 2010 as the subject of color analysis. The result of the study could be summarized as follows: First, the color range of beige consisted of the standard color from 2.5YR to 5YR, and color tone was pale and light gray. Second, the analysis of color beige that appear in contemporary fashion didn't show big differences according to year, season, and region. The color tones consisted of light grayish, pale, light, soft focusing colors from 5YR to 10YR. As for the arrangement of colors, it was arranged with black and it was used with the affiliation of YR, R, Y in many cases. Third, beige monochromatic image appeared soft, plain and classic. The arrangement of the image, modern, feminine, luxurious, gentle, intelligent five types were derived. Arrangements with achromatic colors were expressed in contemporary and sophisticated styles and arrangements with chromatic colors appeared to be soft, feminine and luxurious. This study draws the result to apply the fashion image of beige that was insufficient in other various color researches to design various color aspects by defining the image of beige that appears in contemporary fashion. Based on practical analysis for the color beige, it is evident that beige is an important factor and a powerful influence on fashion images.

  • The purpose of this study is to classify Avatar fashion style through analysis of on-line Avatar Mall and to propose color pallette and fashion contents from fashion color analysis. The literature research focused on investigating the notion, characters and types of Avatar and relation of Avatar and self-image, clothing image and color image. In data research, 4 on-line portal sites Avatar Malls were analyzed and Avatar fashion style was classified. In addition, Avatar clothing color was analyzed. The research of this study are as follows: Firstly, Avatar in the cyber space represents 'me' of the real states. Avatar fashion helps to represent Avatar Image and clothing makes human image and identity as a social sign. Color helps to constitute clothing impression and human image, therefore clothing and color are the important elements to express self-image through Avatar in the cyber space. Secondly, Avatar Malls of 4 on-line portal sites are very similar and confuse Avatar users because of no standard of fashion style classification. Accordingly, the standard of fashion style classification should be made by a fashion expert, and the specific characters of every on-line portal site should be emphasized. Thirdly, as a result of the analysis of Avatar's clothing, the clothing is divided into a real world clothing and an imaginary world clothing. There are daily clothes, uniform, event clothes, story clothes and fantasy clothes. As a result of the color analysis of Avatar clothing, White, Red, Red Purple colors and bright and vivid tone are generally used for Avatar clothing. This study is significant to classify Avatar fashion style systematically, to notify sensitive and delicate users' sign and to make Avatar fashion image emotional and high-quality.
