The background of the study is to experiment with the color glass plaster technique and the resist printing technique which are newly developed with the motif of natural leaves, and to make an interior vase added with new and unique decoration by fusing with ceramic vases. First research and development method is to describe the color glass plaster technique. Second is to explain the resist printing technique and study the decoration method. Third is to examine the history and kinds of vase. And lastly, it is to design 16 vases contemporarily, and use the leaves to experiment with oxidation and reduction of white porcelain and celadon. This experiment acquired the unique color expression by yaobian, and the soft, warm brown resist printing gradation was formed around the leaves. It will get good effects and results by expanding and applying the unique experiment effects to living interior porcelain, molding porcelain, and industrial porcelain.

방염제품의 내구신뢰성은 국민의 화재 안전성 확보를 위한 필수 불가결의 요소로 이들 제품의 내구성능 예측은 방염성능의 지속적 유지를 위한 방염시설물 유지 관리 측면에서도 상당히 중요하다. 본 논문에서는 방염도료의 내구신뢰성 예측 및 확보를 위한 방염도료 가속수명법에 관한 연구로써, 방염도료의 고장 원인분석을 진행하였으며, 현장시험 및 현장 모사 실내 가속촉진시험을 진행하였다. 실내 가속촉진시험은 방염도료의 현장 주고장모드인 온 습도 사이클 시험으로 진행하였으며, 시험 척도로서 화학발광을 분석하여 적용하였으며 현장 데이터와 실내 촉진데이터와의 상관성 규명을 위하여 Mitab 등의 통계적 기법을 이용하여 고장유형 및 상관성을 규명하였다.

Flame resistant treatment has been applied since 1973 for fire prevention in historical wooden buildings, but several problems, such as whitening and discoloration are constantly occurring in some Dancheong, in spite of evaluation criteria. It is supposed that these phenomena are caused by the stability issue of flame retardant, Dancheong production methods, the residue of chemicals, which were applied in the past, building location environments, etc., but no evaluation and cause inspection has been performed. Therefore, this study aims to verify the effect of flame retardant on Dancheong by producing Pseudo-samples and setting spatial and temporal environment conditions. Pseudo-samples of Dancheong were produced using three methods; the method specified in the Standard Specification of Properties; the method, which is generally used in the site and the traditional method. For different environment conditions of pseudo-samples, the areas were classified into a coastal area and an inland area and the places were classified into a sunny place and a wetland. After applying a flame retardant, annual variations were inspected for 12 months and change aspects were observed through scan and regular observation. In annual variation inspection, various variations like whitening, decolorization, dissolution and exfoliation were found and especially, whitening was most dominant. When the effect of flame retardant depending on the production methods was analyzed, whitening occurred in all the three production methods. It is supposed that this is because calcium(Ca) was contained in the coloring material of each production method and it reacted with phosphorous(P) of flame retardant. When the effect of flame retardant depending on the environment conditions was analyzed, whitening occurred more in the coastal area than in the inland area and it reduced in the building in a sunny place, which was constructed using the traditional method. It is supposed that this results from the humidity change and the difference of glue used in each production method. In conclusion, for using a flame retardant containing phosphorous(P), there is a need to check if calcium components including Oyster Shell White were used in Dancheong in advance and to conduct various preliminary studies on place conditions and Dancheong construction conditions.

Opportunistic mycotic infection of mammary gland due to Candida tropicalis is described in a 7-year-old Holstein Friesian cow with a history of prologned use of antibiotics and corticosteroids. C. tropicalis was repeatedly isolated from the mastitic milk on simplified sunflower seed medium at 30$^{\circ}C$. The pathogen was directly detected in the infected milk by 'PHOL' technique. Microscopic examination of Gram stained smears of milk sediment revealed numerous yeast cells and hyphae morphologically consistent with Candida spp. In vitro drug sensitivity test indicated that C. tropicalis was sensitive to nystatin. Chemotherapy with intramammary infusion of nystatin was successful as evidenced by clinical and mycological observations. It emphasizes the growing significance of Candida spp. and other opportunistic fungal pathogens in Veterinary medicine.

In modern life, interior decoration has been transformed into a psychological synergistic effect of space, greatly affecting human sensibility. The main point of view in this paper is to study the discovery of new decorative effects and the possibility of products that can replace imported tiles, which account for more than 60% of the walls of indoor spaces closely related to daily life. The solution is to create point tiles using color glass plaster techniques developed in 2018 and to explore the possibility of decorating art walls to meet consumers' purchasing needs using simulations. The four patterns applied to the a paintbrush, resist printing, cutting technique, and inlaid patterns, and the traditional color development effect of the medium color suited to our sensibilities was studied. In addition, through simulation, art walls and acrylic using color glass styles were also used in the kitchen, living room and empty space of the bathroom. Based on this research, ceramic point tiles with a new perspective will be explored and the interior using walls will be activated.

Clamp resist dyeing is a resist dyeing technique in which a fabric is sandwiched between two or more pieces of woodcarving and then a pattern is expressed by dyeing. Records from nine years of King Heungdeok's reign during the Unified Silla dynasty show that the use of the clamp resist dyeing technique was banned for different garments. This was only for garments of YOOKDUPUMNYEO (六頭品女) or OHDUPUMNYEO (五頭品女). Given this, it can be assumed that clamp resisted fabrics were widely used, and the technique had been established during the Unified Silla dynasty or before. However, only the term can be found in the records. Neither its definition nor how this technique was used is explained. Also, it is difficult to assume the types and features of clamp resist dyeing due to a lack of materials. A small number of relics from the Goryeo dynasty still remain, though. Craft techniques have developed through international exchanges and have changed according to respective nations' circumstances including politics, economics, society, and culture. Hence, this research analyzed documents and relics from China and Japan, two countries neighboring the Republic of Korea, and studied the different types and features of clamp resist dyeing techniques. Clamp resist dyeing techniques were divided into monochromatic or multichromatic according to the number of colors that represented patterns, rather than according to the respective nations' features. They were also classified into mono, bilateral symmetry, or vertical-bilateral symmetry according to the structure of the patterns. Through the study of examples of inherited or reproduced dyeing techniques in China and Japan, it was confirmed that different engraving techniques, including relief, openwork, intaglio fit for the feature of a pattern and the number of colors, were applied in order to vividly represent patterns on fabric. Using small flower pattern clamp resist dyed fine tabby in Amitabha of 1302, the only relic showing its patterns and colors in Korea, as the experiment subject, this research successfully reproduced a clamp resist dyeing technique through a successful experiment based on the basic materials from the dyeing technique case study. Due to the significance of the experiment on a clamp resist dyeing technique that stopped its transmission and shows the features of the technique, this study is expected to be a basic resource that can be used for future reproductions of multichromatic clamp resist dyeing techniques. Also, it is expected to be helpful in widening and recreating the world of Korean pattern dyeing with modern dyeing techniques.
