Roofing tiles are very important archaeological artifacts which show science, architecture of that time, as well as information about the culture. It has been studied by many researchers steadily, but only focusing on archaeological, art historical and architectural study, so it is very difficult to find natural science research. Gyeongbokgung's roofing tiles were excavated from the ruins of same site, however glaze, body colour and shape of tiles are very diverse with the naked eye. Through natural science research which analyze the chemical composition and physical characteristics of roofing tiles's body and glaze examine the physical and chemical characteristics of each roofing tiles. the result of analazed roofing tiles is following. when roofing tiles were classified by 전암대자율 and chromaticity, each group has part of some matches. When you compare with green gazed traditional brick's glaze of Silla period, Gyeongbokgung roofing tiles have more $Al_2O_3$ and less PbO than Silla period's. We can see the technology of increasing firing temperature is better. and glaze colour depends on content of $Fe_2O_3$ and CuO. A lot of CuO tend to be more blue.

This study was conducted for the histological observation of the infundibulum of the oviduct of the laying Korean native pheasants. The results are as follows : 1. The infundibular wall is composed of the epithelium, lamina propria, muscle layer(inner circular and outer longitudinal muscle), and serosa. The funnel lip is divided into the inner, and outer lip of the epithelium and muscle layer. 2. The epithelium of the funnel lip and most region of the cranial part of the funnel are composed of ciliated columnar cells. In the surface and lateral part of the folds, ciliated cells and non-ciliated secretory cells tend to alternate in the epithelium of the caudal funnel and the necks, but are also found in groups of the simple cuboidal epithelium at the bases of the grooves between the ridges and tubular glands found in the subepithelium. 3. The secretory material of the non-ciliated secretory cills contains PAS-positive and alcian blue-positive granules, and these materials show purple colour in the basic fuchsin-methylene blue stain. 4. The cells of the glandular groove and tubular gland of the neck portion of the oviduct mostly show weak PAS-positive, and alcian blue stain negative reaction. The tubular gland cells of the infndibulum contain pink of purple colour granules, and without reaction in the anterior neck portion of the infundibulum in basic fuchsin and methylene blue stain.

Different papers such as toilet and towel tissue, newsprint and copy paper made from reclaimed fibres were characterized using UV-VIS reflectance and fluorescence spectroscopy. The emission properties of the extracts of the papers were also evaluated. Photochemical irradiation at ambient temperatures, and thermal aging of the copy papers at 105$^{\circ}C$ and 150$^{\circ}C$ were performed. Post-colour numbers (PC) were calculated from the reflectance values measured from the corresponding UV-VIS reflectance spectra. Light absorption coefficient spectra were calculated before and after irradiation, and the changes in absorption coefficient were related to the content of chromophores in the papers. Photochemical and thermal discolouration of the copy papers, similar to that of virgin fibres, was readily observed. The influence of changes in the concentrations of fluorescent brightening agents and dyes on the spectral properties was also assessed. Photostabilization studies of the copy papers were performed with the use of polymer additives polyethylene glycol (PEG) and polytetrahydrofuran (PTHF).

We have performed a spectroscopic study of globular cluster (GC) system associated with the Virgo cD galaxy M87 using the Subaru/FOCAS MOS mode. We derive ages, metallicities and abundance ratios from the GC spectra using Simple Stellar Population (SSP) models. The metallicity distribution function (MDF) obtained empirically based on Milky Way GCs is consistent with the MDF derived from SSP models. A comparison with a meta-analysis using literature data sample of 15 other GC systems shows good agreement with our results. The properties of GCs acquired from the spectra will be used to test the recent theoretical prediction of a significant inflection along the colour-metallicity relations (Yoon et al. 2006). If confirmed, the non-linearity of the relations would shed new light on the interpretation of the GC colour bimodality. The robustness of our results is being tested against the choice of a SSP model, measurement errors and sample selection towards the goal of better understanding the formation history of GCs and host galaxy.

The dress and ornaments in the Taijiang were fashionable, which were densely populated with Miao nationality. Women's traditional festive dress in Taijiang included an embroidered blouse and a pleated skirt. The garments are decorated with plenty of ornamental designs. The colours of festive dress were as rich and gorgeous as those of fashinable desses. Embroidery was very popular in Taijiang and its principal feature is embroidery with loose, coloured floss silk. The image of patterns changed ingeniously and colourfully but do harmony. In the using of colour, one kind of the festive dress was in the main red, which means a bright dress. The colour of another kind of festive dress was blue, which means a dark dress. There were many kinds of silver ornaments for women. Taijiang was most outstanding in this respect. The great variety of silver ornaments was a unique feature of women's dress in Taijiang.

The purpose of this study was to analyze the form and meaning of shaman's costumes worn by each gutgeori in Seoul jaesugut and to derive the characteristics of Shaman's costume at gutgeori. Observational research was conducted for three years by participating in the site of two types of gut, which are divided into local jaesugut for the well-being of the region and individual jaesugut that takes place based on personal request. Seoul jaesugut consists of 12 different gutgeori according to the deity it serves and meaning: Bujeongcheongbae, Gamangcheongbae, Bulsageori, Sangeori, Josanggeori, Sangsangeori, Byulsanggeori, Sinjanggeori, Daegamgeori, Seongjugeori, Changbugeori, and Duitjeon. The shape and colour of the shaman's costume worn in each gutgeori are related to the meaning of the gutgeori. Followings are the characteristics of the shaman's costume from gutgeori. First, shaman's costume adopted traditional costumes that symbolized the characteristics of god represented in each gutgeori. Second, gutgeori consists of multiple gods, and shaman's costumes were adopt to represent the superior god among these gods. Third, sometimes the costumes were adopted according to the characteristic of the god instead of its divinity. Fourth, even if the gods were different, if the roles of the gods were the same, the same form of shaman's costume could be taken. Fifth, the process of gut showed the harmony of yin and yang using the principle of five elements through the colour of shaman's costume.

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 the study is to give new aesthetic values of black dress one of the important items in contemporary women＇s fashion. Through the work, to give the new aesthetic characteristics that women really needed can be found. This study was processed by fashion books and articles, literal material with fashion photos which were related fashion trend from 1920 to the present. The results are as follows: In early 20th century, the black dress, which had simple form pursuing function like little black dress. In the middle of the 20th century, elegance and minimalism was represented by black dress, expressed erotic images together with see-through fabrics. In the end of the 20th century, body conscious style of black dress expressed sensual images of women. Modem black dress has design characteristics of the form: simple, close, exposure type and of the materials: matte, transparent and dazzling etc. Simple type emphasizes feminine elegance, while close type and exposure type disclose woman body curve to express erotic images. Matte materials made black dress express feminine elegance while transparent materials and dazzling materials made black dress express erotic and sensual beauty. The aesthetic characteristics of black dress were as followings: Sensualism expresses sexual attractiveness of women-close type and exposure type black dress and see-through materials and dazzling materials made black dress. Simplicity of extreme decoration effects are expressed through black dress having temperate and simple form. Femineity expresses traditional femineity to emphasize chaste, modest and elegant women images-the black dress, which is made of simple form, velvet and satin materials. Modernism combines black colour, which is called modem colour, with simplicity and function factors and pursues simple form. Ascetic practice controls mental and physical desire of the individuals, simple form without decoration covering up woman body and box type silhouette of black dress. Therefore, the study on image of the black dress, which have made appearance at modern fashion, is thought to help develop fashion trends and design, through which modern women express themselves and their beauty.

PVC를 염색하는 방법에는 분산염료, vat 염료, 함금속염료, 산성염료 등이 보고되고 있다. 그러나 PVC는 의류용 사로 적용되는 예가 적기 때문에 이의 염색에 대한 연구 결과도 상대적으로 드물다. 가발용 사를 만드는 공정의 경우 PVC 방사 시 안료를 배합해 유색 PVC를 얻는 방법에 대한 문헌이 약간 있을 뿐 PVC의 염색에 관한 자료는 거의 찾아보기가 힘들다. 최근 PVC 사의 용도가 다양해지고 있고, 가발용 원사로 이용되는 경우 안료를 배합한 방사법만으로는 two tone colour 등 가발용 원사로서의 다양한 요구에 부합되지 못하므로 후염색에 의해 PVC를 염색하는 방법의 필요성이 요구된다.
