탐색자가 정보 요구를 정보검색시스템에 표현하는 능력은 검색과정의 기본이다. 시각적 예시에 의한 질의는 내용기반 이미지 검색환경에서 질의 표현을 위한 중요한 패러다임이다. 하지만, 이 방법이 질의 구성의 편의성에 있어 얼마나 효과가 있는지에 대한 실험적 입증은 아직 미미하다. 이 연구의 목적은 다양한 정보요구와 효율적이고도 효과적인 시각적 질의 구성을 지원하기 위해 탐색자의 정보요구와 질의 방법 사이에 발생하는 지식 격차를 고려하여 색을 이용한 질의 방식의 사용성을 조사하기 위한 것이다. 본 연구결과를 통하여 색을 이용한 질의 방법이 시각적 질의 구성을 적절히 지원하지 못한다는 것과 탐색자의 정보요구와 검색 패러다임의 표현력 사이에 뚜렷한 불일치가 있다는 것을 알 수 있다.

The purpose of this study is to analyse the fashion image behind the colour black formed by existentialism in the 20th century. Human beings started to ask themselves questions about their nature and existence by undergoing two world wars in the 20th century. Existentialism was born out of these philosophical thoughts and in particular, French existentialists led the public discourse of the time and expressed their philosophical thoughts and ideas through black fashion. Therefore we revealed the existentialistic meanings of black by studying the French existentialist ideology and their black fashion. The thoughts of existentialism became popularized in France by French philosophers. Sartre especially played a big role in the popularization of existentialism in France. The black fashion worn by existentialists became popularized along with the ideology that it expressed. Sartre's thoughts on existentialism are summarized in existence Precedes Essence, self-reliance, and engagement. From these, the fashion image behind the colour black formed by existentialism was analogized to resistant image, nihilistic image and self-reliance image.

After drawing the sensory images from the color green, the difference of sensory images and the difference of the color green according to demographic characteristics and which factors affect the preference have been analysed. The thirty six-photos of 2013 women fashion show on the STYLE.COM were used for the stimuli of green colour fashion for the questionnaire. The people surveyed were adults in their 20s to 50s. The 123 copies of the questionnaire were used for the statistical analysis of this study. Factor analysis, Cronbach's ${\alpha}$ test, t-test, ANOVA, Duncan test and Regression analysis test were carried out by SPSS 19 for the statistical analysis of collected data. The results were as follows. The sensory images of green fashion were drawn in six types. The sensory images of green fashion according to demographic characteristics showed a significant difference depending on martial status, age, monthly income and occupation. The preference of green colour fashion according to demographic characteristics showed a significant difference depending on sex, age, monthly income, occupation. The variables affecting the preference of green fashion were identified as four types, and the most affecting variable to the preference was the favorable and familiar factor. These research results will become available on selecting the target customer and making the marketing differentiation strategy when planning fashion products.

A study was made on the feature extraction for non-metallic one deposits and their related geology using the Remote Sensing and Airborne Radiometric data. The area chosen is around the Haenam area, where dickite and Quarzite mines are distributed in. The geology of the area consists mainly of Cretaceous volcanics and PreCambrian metamorphic. The methods applied are study on the reflectance characteristics of minerals and rocks sampled in the study area, and the feature extraction extraction of histogram normalized images for Landsat TM and Airborne Radiometric data, and finally evaluation of applicability of some useful pattern recognition techniques for regional lithological mapping. As a result, reflectances of non-metallic minerals are much higher than rock samples in the area. However, low grade dickites are slightly higher than rock samples, probably due to their greyish colour and also their textural features which may scatter the reflectance and may be capable of capturing much hychoryl ions. The reflectances of rock samples may depend on the degree of whiteness of samples. The outcrops or mine dumps in the study area were most effectively extracted on the histogram normalized image of TM Band 1, 2 and 3, due to their high reflectivity. The Masking technique using the above bands may be the most effective and the natural colour composite may provide some success as well. The colour composite image of PCA may also be effective in extracting geological features, and airborne radiometric data may be useful to some degree as an complementary tool.

Image quality analysis has been carried out for both monochrome and colour print images obtained by a calibrated low-end scanner. The analysis method is based upon ISO13660 for monochrome images and additional criteria for colour quality that we have defined. We have compared performance of the calibrated scanner with that of a high-end spectrophotometer in terms of several aspects such as line and large area. They have provided similar results without significant discrepancy.

'Naturalness'의 경우 화질 평가에 있어서 중요한 요인으로 여겨진다. 'Naturalness'는 다른 감성이 부여되는 이미지의 컨텐츠에 의존하는 중요한 요인이다. The Image Quality Circle은 한 단계에 해당하는 'ness' 단계를 두 가지로 나누었다. 두 단계 중 하나는 lightness, colourfulness, hue and contrast와 같은 지각 속성을 예측하는 단계이다. 다음 단계는 이미지의 컨텐츠에 따른 SSE를 찾는 단계이다. 이 연구에서 이미지들은 TV장르로 분류해 놓았다. 각각의 이미지들은 lightness, colourfulness, hue and contrast를 단계별로 변형시켰다. 각 변형된 이미지의 화질 점수와 SSE의 점수를 실험 참가자들에게 물었다. 정성적 항목에 7 점 단계의 정량적 평가를 실시하였다. 각 장르에 따른 세 가지 SSE를 변수로 이용하여 화질 평가 모델을 수립하였다. 생생함 (vividness)은 모든 장르에 공통으로 존재하는 SSE이고 나머지 SSE들은 모두 모델에서 독립변수로 취급하였다. 그 후 색 속성을 이용하여 각 장르에 따른 생생함을 예측하는 모델을 수립하였다. 생생함은 각 장르에 따라 의미가 다르며 화질 평가와 자연스러움(Naturalness)룰 연결하는 중요한 요인이다. 각 장르마다 생생함이 다른 의미로 여겨지기 때문에 각 장르에 생생함을 최적으로 표현하는 색 속성 또한 장르마다 다를 것이다.

Although upper respiratory tract infections (URTIs) are common diseases, there have been no studies of their relationship with the indices obtained from tongue image analyses. The purpose of this study was to identify a tongue index through an analysis of tongue images (TIs) showing significant changes before and after treatment in patients with URTIs. A computerized tongue image acquisition system was developed to acquire TIs from subjects in the same environment. An image was taken from each of 39 URTI patients and 39 healthy controls. For the patients, images were acquired before and after treatment to identify changes. The tongue area was classified into a tongue body and a tongue coating, and the coating ratio between the two areas, the average value of the colour of each area, and teeth marks were calculated. No significant difference was observed in age or sex between the URTI patients and control participants. Heart rates were slightly different. The analysis of TIs showed that the luminance of the tongue coating and the coating area ratio were decreased, while the reddish value of the tongue body at the centre area increased as the treatment progressed. Tongue coating and body in URTIs had different colour and shape from those in the normal. It is expected that this result will contribute not only to the objectification of traditional Chinese medicine but also to diagnostic methods that do not involve face-to-face physician visit during the pandemic.

The purpose of this study was to analyze the expressive characteristics of Chinese shadow puppetry costumes. Literature study and case analysis were conducted using books, research papers, and materials from the Xi'an shadow puppetry museum. Based on the Chinese traditional costumes, the shape characteristics are utilized with the intaglio and embossing techniques, and the complex and unnecessary details are omitted to express the costume image in a characteristic and simple manner. Second, colour was used according to the traditional Chinese symbolic colour concept, and the brighter the colour, the higher the role's status. The colour was also used to express identity and character. In addition, relatively vivid and highly saturated colours were used for the transparent effect of the shadow puppetry. Third, a role's status is indicated by the density and completeness of the patterns; the higher the role's status, the more complex and sophisticated the patterns, and the lower the status, the simpler the patterns or no patterns are used. Fourth, the faith for blessing expressed in the shadow puppetry is a representative folk auspicious culture. The repertoire of the shadow puppetry and the patterns on the costumes worn by the puppets, express the culture in an implicit way to symbolize the meaning of auspicious things.
