이 연구에서는 국가지정 목조건축문화유산 현장에서 수습한 등황 채색시료를 분석하여 특성을 규명하고 이를 근거로 채색기법을 재현하여 채색 기법에 따른 발색 및 색 안정성을 평가 하였다. 문화유산 현장에서 확인된 전통 등황 단청의 채색기법은 주로 백색 안료로 밑칠을 하고 등황을 중첩 채색하였다. 백색 안료에는 연백, 백토가 단독 또는 혼합 사용되었다. 이를 근거로 재현시편은 등황 하부에 연백과 백토 안료를 단독 또는 혼합하여 밑칠한 중첩채색 기법으로 제작하였다. 또한 대조군으로 백색 안료와 등황을 혼합하여 칠한 혼합채색 기법을 제작하고 재 현시편을 대상으로 촉진내후성시험을 실시하였다. 이 결과, 등황 채색시편은 색차값(ΔE)이 모 두 40이상으로 색 보존성이 취약하여 유기안료의 재료적 한계를 확인할 수 있었다. 그러나 시험 전후 모두 혼합채색에 비해 중첩채색의 황색도가 높고 특히 중첩채색 중에서도 밑칠로 연백을 사용할 때 황색도가 높았다. 이를 통해 밑칠로 연백을 사용하고 등황을 중첩채색한 기법의 발색 과 보존성이 좋은 것을 알 수 있었다.

This study, analyzed painted pigment samples to investigate the coloring characteristics of the organic pigment Deunghwang. In particular, reproduction specimens were prepared using traditional Dancheong samples, and color development and accelerated weathering tests were conducted to evaluate the color stability of Deunghwang as per different coloring techniques. The traditional painting technique of Deunghwang confirmed that cultural heritage sites primarily involved the application of a base coat with white pigment followed by an overlapping paint of Deunghwang. In terms of white pigment, either Yeonbaek, Baekto, or a combination of both was used. Consequently, the reproduction specimens were created using the overlapping coloring technique wherein either of Yeonbaek, Baekto, or a combination of both was applied on the lower part of Deunghwang. Further, a mixed coloring technique was developed by mixing a white pigment and Deunghwang as the control group. Thereafter, an accelerated weathering test was performed on the reproduction specimens to evaluate the coloring layer preservation. The weathering test results indicated that, the color difference value of the Deunghwang specimens exceeded a vlaue of 40(ΔE), indicating poor color stability, and confirming the material limitations of organic pigments. However, both before and after the test, the yellowness of the overlapping coloring was higher than that of the mixed coloring, particularly when using the Yeonbaek pigment as an undercoat in the overlapping coloring, Thus, we conclude that the technique of using the Yeonbaek pigment as a base coat for overlapping with Deunghwang facilitates good color development and preservation properties.

Background: The poultry industry suffers losses from problems as pale, soft and exudative (PSE), and dark, firm and dry (DFD) meat can develop in meat as a result of short- and long-term stress, respectively. These abnormalities are impacted by pre-slaughter animal welfare. Methods: This work evaluated the effects of open vehicle container microclimate, throughout the 38 ± 10 km journey from the farm to the slaughterhouse, on commercially turkey transported during the Brazilian winter season. The journey was initiated immediately after water bath in truck fitted with portable Kestrel anemometers to measure air ventilation, relative humidity, temperature and ventilation. Results: The inferior compartments of the middle and rear truck regions showed highest temperature and relative humidity, and lower air ventilation. In addition, the superior compartments of the front truck regions presented lower temperature and wind chill, and highest air ventilation. The breast meat samples from animals located at the inferior compartments of the middle and rear truck regions and subjected to with water bath (WiB) treatment presented highest DFD-like and had lowest PSE-like meat incidence than those from animals located at other compartments within the container. Lower incidence of PSE-like meat was observed in birds without water bath (WoB). Conclusions: Assessment on turkeys transported under Brazilian southern winter conditions revealed that breast meat quality can be affected by relative humidity, air ventilation, temperature, and transport under subtropical conditions promoting color abnormalities and the formation of simultaneously PSE-like and DFD-like meat.

For the purpose of preparation of monodispersed spherical zinc oxide fine particles, and experimental research on the preparation of zinc oxide particles from zinc salts solutions by high temperature precipitation reaction was performed. Zinc oxide particles were precipitated from all the precipitation solutions tested if the precipitation temperature was higher than 60C. As the precipitation temperature increased until 80C, the average particle diameter of zinc oxide particles decreased and the narrower particle size distribution were obtained. Spherical zinc oxide fine particles with relativeyl narrow particle size distribution were precipitated from the ZnSo4 solutions with NaOH as precipitant. Final pH of precipitation solution had an effect on the amount of zinc oxide precipitated, but had no effect on the their particle size or size distribution.

In recent year, many imaging systems have been developed, and it became increasingly important to exchange image data through the computer network. Therefore, it is required to reproduce color image independently on each imaging device. However, even if the image are same, perceived color is not always same under different viewing conditions. On the other hand, even if the image are different, we want to perceive same color under different viewing conditions. Therefore we must know the spectral reflectance information of object. We measured many reflectance human skin can be estimate using only three principal component. For Munsell color patches, five principle components were necessary to estimate the reflectance spectra. For that purpose, we have developed color image acquisition system that is composed of five band filters and CCD camera. Improved spectral reflectance of object is predicted by five band images taken by color image acquisition system and then we take account of camera's noise and component of object image for predicting accurate spectral reflectance of object. In the results, we confirmed that color difference and MSE(Mean Square Error) between measured and predicted spectral reflectance of object decreased into 0.0071 and 7.72 respectively.

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, 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. 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. In these studies, a population is fixed, first, on ab coordinates of CIE Lab. 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 Lab. 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.

This study aims to develop and propose new hair color design trends by hair length using generative AI, focusing on the 2026 Pantone colors, the global standard for color. Methodologically, prompts were structured by extracting core keywords aligned with the design concepts. These prompts were iteratively refined to correct morphological errors and color distortions from the AI, thereby producing highly complete final images. Specifically, the ombre dyeing technique was applied to long hair to create a sophisticated and elegant look. For medium-length hair, the dip-dye technique was utilized to project a sporty and lively vibe. For short hair, the weaving technique was employed to realize a luxurious image by enhancing three-dimensional depth through tonal contrast. The findings of this study are as follows: First, generating hair designs that perfectly align with the intended concept via AI requires the user’s expertise in professional beauty terminology and precise prompt control capabilities. Second, the hair color designs derived from this study harmoniously integrate color, hair cut, and styling, presenting practical and aesthetically appealing trends that satisfy consumer needs in the contemporary beauty market. Third, generative AI serves as a powerful tool capable of intuitively visualizing planning intentions, suggesting its significant potential as a visual communication medium for marketing content planning and customer consultations in the future beauty industry. However, as this study relied on specific Pantone color names, visual discrepancies may exist between the AI-generated colors and the actual results achieved with chemical hair dyes in a salon environment. To narrow this gap, subsequent studies incorporating actual chemical hair dye data are necessary. Furthermore, future research should focus on systematizing generative AI prompts to develop an 'AI-based hair color design and content production guide' that beauty professionals can easily apply in practical settings.

The tooth colorant of chemical sanctions currently in use raises controversy over the risk of colorants, and it is also difficult to supply and demand as it is classified as a non-medical product. Therefore, in this paper, a dental colorant was developed using natural materials and implemented to find out the sense of use and efficacy thereof. The composition of the natural coloring agent was prepared by mixing gardenia seeds pigment, xanthangum, stevia, and food blue no.1, and after performing a functional test, one was selected and the effectiveness was compared by coloring the subject before prophylaxis. As a result, it showed a similar effect to the tooth coloring agent currently used, and it was derived that the aroma and taste should be supplemented. It is hoped that it will help the development of dental colorants using natural materials in the future, and that it will be a draft for the commercialization of natural coloring dyes.

최근 3D프린터의 발전에 따라 실제 제품과 유사하게 제작하고 싶은 니즈가 늘어가고 있다. 이에 따라 FDM 풀 컬러 3D프린터가 개발되어 활발하게 보급되고 있으나, GUI디자인은 그에 미치지 못하여 사용자로 하여금 혼란을 야기한다. 이에 따라 본 연구는 문헌조사를 진행하였고, 사례 조사를 통하여 FDM 풀 컬러 3D프린터의 현황을 파악하 고 선행연구를 바탕으로 GUI디자인의 구성요소를 분석하였다. 도출한 GUI디자인의 구성요소에 맞춰 체크리스트 초안 을 도출하였으며, 세 차례의 델파이 조사를 통해 초안 50항목 중 24항목을 삭제하였으며 나머지 26가지 항목에 대한 타당성을 검증하였다. 그 결과 레이아웃은 직관적인 화면 구성과 사용빈도가 높은 메뉴 위주로 구성하여야 하며, 텍스트 는 직관적으로 눈에 띄며 기능을 명확하게 전달하여야 한다. 또한 아이콘은 눈에 잘 보이는 위치에 위치하고 실생활에서 차용하여 이미지화하여야한다. 마지막으로 컬러는 강조색을 사용하여 사용자에게 피드백을 주고, 출력물과의 색상이 겹 치지 않도록 하여야 함을 알 수 있었다.

With the recent development of 3D printers, there is a growing need to make them similar to real products. As a result, FDM full-color 3D printers have been developed and actively distributed, but GUI design has fallen short of that, causing confusion among users. Accordingly, this study conducted a literature survey, and through a case study, the current status of FDM full-color 3D printers was identified and the components of GUI design were analyzed based on prior research. The draft checklist was drawn up according to the components of the derived GUI design, and 24 items were deleted through the three Delphi surveys and the validity of the remaining 26 items was verified. As a result, the layout should consist of intuitive screen configuration and menus with high frequency of use, and the text should be intuitive and clearly communicated. In addition, the icon should be placed in a visible position and used in real life to image it. Finally, we could see that the color should be used to give feedback to the user using the highlight color and not overlap the output.

The CMS(color management system) software was to enable consistent color reproduction from original to reproduction. The CMS was to create RGB monitor and printer characterization profiles and then use the profiles for device independent color transformation. The implemented CMM(color management module) used the CIELAB color space for the profile connection. Various monitor characterization model was evaluated for proper color transformation. To construct output device profile, SLI(sequential linear interpolation) method was used for the color conversion from CMYK device color to device independent CIELAB color space and tetrahedral interpolation method was used for backward transformation. UCR(under color removal) based black generation algorithm was used to construct CIELAB to CMYK LUT(lookup table). When transforming the CIE Lab colour space to CMYK, it was possible to involve the gray revision method regularized in the brightness into colour transformation process and optimize the colour transformation by black generation method based on UCR technique. For soft copy colour proofing, evaluating several monitor specialism methods showed that LUT algorithm was useful. And it was possible to simplify colour gamut mapping by constructing both the look-up table and the colour gamut mapping algorithm to a reference table.

For this, a simulated environment was created, and LD values of red, green, and yellow color were collected by increasing the luminance. From the test results, the LDs for red at luminance levels of 2,000 cd/m2 and 20,000 cd/m2 and a visibility distance of 10m were 10.2m and 18.8m, respectively, which was an improvement of 84%. The LD was improved by 34% and 17% at a visibility distance of 20 m and 30 m, respectively. For green, the LD was improved by 69%, 63%, and 19% at visibility distance of 10m, 20m, 30m, respectively. For yellow, the LD was improved by 100%, 47%, and 36% at visibility distance of 10m, 20m, 30m, respectively. The LD models for three colors were developed by using two independent variables, luminance value and visibility distance. The adjusted coefficients of the red, green, and yellow model equations were calculated as 0.982, 0.978, and 0.915, respectively, and the explanatory power of all models was very high.

A novel device for foot reflexology that utilizes color light stimulation has been developed and the efficacy of the device has been tested as a basis study. The new foot color reflexology device is designed in a way so that color light can separately project red, orange, yellow, green, blue, and violet color lights to various neural reflex points on foot for a certain amount of time. The efficacy of the device was studied with seven young healthy subjects by measuring various physiological signals and foot related parameters before and after the treatment of the foot color reflexology. The measured physiological signals were bodily temperature, blood pressure, pulse rate, and heart rate variability(HRV). The measured foot related parameters were foot surface temperature, foot instep circumference, volume and peripheral plethysmograph(PPG). The results showed increase in bodily temperature, foot surface temperature and decrease in pulse rate, HRV, foot instep circumference, and foot volume. Therefore, the foot color reflexology seems to be effective in reducing stress and relaxing mind and body.
