  • Some chromophores that can undergo a pronouncend colour change when acted upon an extenal agency, such as light, heat, pH, or chemical agents, have many potential applicationa as functional dyes. They may be used as indicators, optical sensors, biochemical probes, optical and thermal recording materials. The results will investigate donor-acceptor chromophores which have the potential for such colour change processes. In particular, cross-conjugated donor-acceptor chormophores, analogous to indigo and squarylium-type chromophores, will be examined for pH sensitizing and for their oxidation-reduction colour change behaviour.

  • This study was aimed at giving help to the people intending to change their hair fashion feeling for changing their own hair colour design and also providing the guide line to the cosmetic circles for developing new hair colour design and promoting sales by statistically analyzing hair colours and the other factors(demographic characteristics, hair styling, total fashion feeling, hair style) of capital area women in their twenties based on the theoretical study on tatal fasion feeling & hair fashion feeling, and hair trend. The researching methods were composed of prior theoretical research, statistical analysis. The prior theoretical research was accomplished by analysis of literatures, magazines and internet sites about total & hair fashion feelings and hair trend. The statistical analysis used a questionnaire composed of 33 questions in 5 categories. The survey of the questionnaire had been conducted from June 15 to June 28 in 2005 on the 600 women in the capital area, investigated by a group of experts on cosmetics or clothing from academic or business society. The analysis of materials from the survey was done by SPSS program(ver. 12.0) using frequency analysis, $x^2$-test and cross tabulation analysis specified on high significant values. Based on the above results of $x^2$-test and cross tabulation analysis, categorized the characteristics of the hair fashion feeling groups, especially hair colours in the order of percentage. This study would be very helpful to the people trying to change their own hair fashion feeling and be useful to the cosmetic circles for developing new hair colour design and promoting sales by comprehending hair colour market and also be valuable to develop the analysis methodology of hair colour and hair fashion trend.

  • The purpose of this design is to find out the design for an ophthalmic hospital focusing on the patient needs and changed healthcare environment. A cellularized hospital system appears variety design. This space needs well-balanced and ease of mind, because of ophthalmic needs a clear description attention. The concept of this design is to give human colour intellect and rich colour-sense. The waiting area wall is finished the graphic design sheet of leaves, which is covered with the fluting glass and indirect lighting. The colour is extracted in nature. The colour techniques of graphic design is gradation, the colour plan select from Y to G-GB. The material is selected within natural colour. The treatment area is functional space and the waiting area is sensitivity space. The hospital design must change with user as a leader.

  • Colour consistency is an important consideration when selecting pigments used on works of art. In this study, we analyse the colour difference between two sets of synthetic blue glass pigments acquired at least 8 years apart from the same manufacturer in Japan. The old pigment set (unused, dry powder with four different grain sizes) appears faded compared to the new set. These pigments are made available for artistic use, commonly in Nihonga or Japanese paintings. Raman spectroscopy and SEM-EDS results characterize these pigments as cobalt aluminate spinels dissolved in leaded glaze, a special class of complex coloured inorganic pigments that is not well-understood in the field of conservation. Colour difference between the old and new pigments with four different grain sizes were quantified by analysing photomicrographs with image analysis software. Blue pigments with coarse and extremely fine grains showed significant colour change compared to pigments with medium and fine grain sizes. The high occurrence of crystallites in the finer grains give a final colour that is bluer and lighter. Possible causes for the colour difference including manufacturing methods and storage environment are discussed.

  • Twelve new species of two genera Smenospongia and Cacospongia (Demospongia: Dictyoceratida: Thorectidae) are described from Gageodo Island and Ulleungdo Island, Korea. Of these, ten new species of the Smenospongia are distinguished from the other nine reported species of the genus by the skeletal structure and sponge colour. Primary fibres of the genus Smenospongia are mostly dense, dark colour, and invisible inside of fibres, but they are mostly cored detritus and echinated with spicules. Especially, the end of primary fibres at the surface shows densely cored with spicules. All these new species changed the colour. Two new species of the genus Cacospongia are compared with nine other reported species. In skeletal structure, primary fibres of the genus Cacospongia are light colour, visible inside and more heavily cored with spicules and sands. The skeleton of this genus has large meshes. The colour of the genus Cacospongia does not change.

  • The purpose of this study was to identify the change and characteristics of 20th Korean women's make-up the result of the study as follows: In the period 1920's 1. The drastic social changes such as civilzation and revolution together with the in troduction of western culture affected make-up and clothes. New women and high school girls wore the modified costume make-up hair style But general public women keep to traditional skin care style and white skin colour was popular. 2. In recent year after 1960's economic de-velopment the women's social status were pormoted after 1970's various colour em-phasize lip eye there by resulting in remark-able modification in the Korean women's apperance. In those days there was the large cosmetic producst of vavious colour 3. The result of this study indicated that the value of recognize the importance of total fashion is the harmonization of clothes and make-up 4. It was also suggested Korean beauty in the future should be achieved in accordance with tradition and modern sense.

  • The intensity-hue-saturation (IHS) technique has become a standard procedure in image analysis. It enhances the colour of highly correlated data. Unfortunately, IHS technique is sensitive to the properties of the analyzed area and usually faces colour distortion problems in the fused process. This paper explores the relationship of colour between before and after the fused process and the change in colour space of images. Subsequently, the fused colours are transformed back into the 'simulative' true colours by the following steps: (1) For each pixel of fused image that match with original pixel (of the coarse spectral resolution image) is transformed back to the true colour of original pixel. (2) The value for interpolating pixels is compensated to preserve the DN ratio between the original pixel and it's vicinity. The 'compensative matrix' is constructed by the DN of fused images and simulation of scaling process. An illustrative example of a Landsat and SPOT fused image also demonstrates the simulative true colour fusion methods.

  • Black-dyed PET fabrics were sputtered with stainless steel through DC-magnetron type device to investigate the possibility of coloration effect, and then considered the morphological structure and physical characteristics such as water permeation ability and washing fastness. Change in color was estimated on the basis of CIELAB color system. The color coordination of metal plated PET was shifted to yellow-red from red-blue. Colour difference$({\Delta}E^*)$ was increased by sputtering conditions with increasing ion current and treatment time. Especially, $Lightness(L^*)$ value of PET was remarkably increased by sputtering, whereas $Chroma(C^*)$ increased gradually. From SEM analysis, rough and uneven craters were found and thickened on the fiber surfaces with longer sputtering time. And washing fastness was a little poor and absorption ability slightly decreased. There were little changes of breaking load and breaking extension. It was evident that observed uneven craters in the plated thin layer resulted in the colour change of PET fabrics by sputtering treatments.

  • 적, 녹, 청색 3파장 LED를 적용한 LCD 백라이트 조명은 백색 LED를 적용한 것에 비해 넓은 색재현성과 LCD 투과율을 실현할 수 있으나, 온도 변화에 따른 휘도 저하와 색좌표 변동 문제 등의 신뢰성을 확보하지 않으면 안된다. 본 논문에서는 정전류 전원을 사용하는 소형 3파장 LED 백라이트 조명에 온도 보상 소자로서 써미스터를 사용한 저가형 온도 보상 장치에 대해 소개하고, 설계 및 실험 결과를 나타내었다. 이 방법에 의해 휘도 저하율을 54% 개선하였고, 색좌표 변동율을 51% 줄일 수 있었다.
