A Beoseonbongip is a pouch that holds patterns for making Beoseons. This study aimed to identify the aesthetic and symbolic contents of the embroidery patterns by analyzing the kind, combination types, expression and arrangement types of patterns. In total, 140 Beoseonbongip artifacts, which were mostly made in the Joseon Dynasty, were quantitatively and qualitatively analyzed. The results indicated that about 83% of the total had flower patterns. Various kinds of embroidery patterns used for Beoseonbongips were newly identified. About 73% of the total had different kinds of patterns. Pattern combination types were identified by the kinds of patterns, the number of paired patterns, and the traditional painting styles used. The patterns of Beoseonbongips were expressed schematically more than realistically or abstractly. Beoseonbongips with different patterns on the four triangle tips of the front face and Beoseonbongips with the same/similar patterns on two opposite tips of the front face were observed more than the other types. On the back face, the embroidery patterns were symmetrically arranged, showing various division structures. It was inferred that wishes (e.g., marital harmony, fertility, good health and longevity, happiness, and wealth and fame) were expressed through the symbolic patterns embroidered on the Beoseonbongips. In terms of Korean traditional beauty, the union with nature, the harmony of yin and yang, symmetric balance, and neatness were also emphasized as a esthetic characteristics of Beoseonbongips.

Vickers hardness is an important material in the design and reliability is required. Therefore, these values are very important as the basic data for design, manufacture and development, and the identification of quantitative probability distribution characteristics such as mean and dispersion is a very important parameter in design. In this study, Vickers hardness was measured after artificially heat-treated in the temperature range 753K, where chrome depletion near the grain boundary occurred for three kinds of stainless steels, and the Vickers hardness were evaluated. From the results, Vickers hardness increased with increasing heat treatment temperature. In Weibull distribution for Vickers hardness, the dispersion of STS310S at 813K and 873K was small, and the dispersion of STS316L at 753K, 933K and 993K was small. Also, STS347H exhibited the lowest dispersion at 753K in three kinds of stainless steels. The scale parameter increased with increasing heat treatment temperature in three kinds of stainless steels.

2매 접합렌즈와 단렌즈로 구성된 2군 렌즈계의 구면수차, 코마, 종색수차 보정을 위한 3차수차 전개식을 얇은렌즈 근사를 이용하여 해석적으로 유도하였다. 유도된 3차수차 전개식은 telephoto렌즈계의 설계에 적용되었다. 초기설계에서 광학유리 조합은crown-flint-crown조합과 flint-crown-flint 조합에 관하여 조사하였다. Crown-flint-crown조합의 경우 2가지 형태의 achromatic aplanat 존재하였다. Flint-crown-flint조합의 경우에서도 2종류의 해가 존재하였으나, 해의 형태가 유용하지 못하였다.

In this study, a change of hand of fabrics dyed with persimmon juice was measured using Kawabata Evaluation System. Using various cotton fabrics, linen fabric and silk fabric used frequently for persimmon juice dyeing, we examined the changes of physical properties and hand according to persimmon juice dyeing and washing. The dynamic characteristics of hand were measured tensile, shear, bending, compression, surface properties, thickness and weight. Linearity of load-extention and tensile resilience were increased in all kinds of fabrics after dyeing. Tensile energy decreased in cotton fabric 2(gauze), cotton fabric 3(muslin) and linen fabric. Shear stiffness and hysteresis of shear increased in most of fabrics. Bending rigidity of the bending property and hysteresis of bending, linearity of compression of the compression property, compression energy and compression resilience increased in all kinds of fabrics after dyeing. Thickness and weight increased much in all kinds of fabrics after dyeing. In the primary hand value, stiffness and anti-drape stiffness increased in all kind of fabrics after dyeing. The fullness and softness, crispness, scrooping feeling and flexibility with soft feeling decreased. As the stiffness after persimmons dyeing increased, it was suitable for clothes material of summer.

This is a study about Jangs presented in the Cheminyosul. Scattered yeast and purified salts are used as ingredients of Jangs. Hwangeui, Hwangjeung and Eol are scattered yeast, and Sangmanyom, Hwayom and Inyom are purified salts. According to their main ingredient, Jang can be classified Kokjang, Yukjang and Eojang. Kokjang was made from soybean and/or wheat, Yukjang made from meat, and Eojang made from fish and crustacea. Eojang is similar to Korean fish sauce, Jeot. Three kinds of Kokjang, four kinds of Yukjang and seven kinds of Eojang are described in the Cheminyosul. Generally, Jangs were fermented and ripened for one day to one hundred days. Also, most of Jangs were made in cold season except Keonjeeojang and Janghae.

The Kinds of soy sauce were prepared using the brick type of conventional meju(A), the brick type of meju of Aspergillus oryzae(B), and the grain type of meju of Aspergillus oryzae(C). Free sugar and alcohol were analyzed in accordance to aging time of those products. Galactose, glucose, arabinose, xylose, and mannose were detected in all kinds of soy sauce. In soy sauce 4 galactose, glucose, arabinose, and xylose were shown in the order of content. The content of galactose in soy sauce A and soy sauce C were shown higher than that in soy sauce B alt during the time. The content of glucose was highest among that of all kinds of free sugars at the beginning of preparation, but the content of glucose was lower than that of arabinose and xylose after 60 days. The contents order of total free sugar was soy sauce C > soy sauce B > soy sauce A. The content of ethyl alcohol was shown 6.23∼19.10mg%, and that of isobutyl alcohol was 8.70∼ 169.03 ppm in all soy sauces, but those of soy sauce C was higher than those of other soy sauces.

Three kinds of soy sauce were prepared using the brick type of conventional menu(A), the brick type of meju of Aspergillus oryzae (B) and the grain type of menu Aspergillus oryzae (C). Organic acid and fatty acid were analyzed In accordance to aging time of those products Citric acid, lactic acid, acetic acid, malonic acid, butyric acid, oxalic acid, and propionic acid were dejected in all kinds of soy sauce. The content of lactic acid was shown higher than those of any other organic acids. The content of lactic acid was much higher at beginning of preparation and at 180 days in soy sauce B than any other conditions. The content of acetic acid was much higher at beginning of preparation, at 120 days in soy sauce C and at 180 days in soy sauce B than any other conditions. The content of citric acid was highest at beginning preparation in soy sauce C, and that was highest in soy sauce B except beginning preparation to 120 days. Myristic, palmitic, stearic, oleic, linoliic, linolenic, arachidonic acid were detected in all kinds of soy sauce after 180 days. The content of oleic acid were shown 32.59∼53.79% in soy sauce B and in soy sauce C. The content of stearic acid was shown 49.7oA In soy sauce A. Linolinec acid and arachidonic acid were detected in only soy sauce C.

In recent years, numerous studies have been carried out to find out the possible substitution of PE-coated paperboards used in packaging of watery or oily foods. Accordingly, this study was carried out to obtain the basic data for producing higher functional coating agents for pulp mold by evaluating various kinds of mixed coating agents. At that time, two kinds of synthetic coating agents(AKD, PYA) and three kinds of natural coating agent(CMC, corn starch, oxidized starch) were used for making the mixed coating agents respectively. Physical properties of coated paperboards were tested. Conclusions obtained from this study were as follows. Based on concentrations, the proper mixture ratios were 10:90(AKD:CMC), 10:90(AKD:corn starch), 10:90(AKD:oxidized starch), 40:60(PVA:CMC), 20:80(PVA:corn starch) and 20:80(PYA:oxidized starch). The mixed coating agent of PYA:corn starch(20:80) was the most efficient coating agent. Consequently, water and oil resistance were improved even with much addition of natural coating agents. We consider that they can be suitable for the packaging used in the storage of higher moisture vegetables and other food, and also can be suitable for oily fried food.

몇 종의 식물자료에서 추출한 염액으로 견을 염색하여 색채를 조사하고 염색견에 3종의 매염제처리를 한 후 세탁 및 내광견도를 조사한 결과는 다음과 같다. 1. Tannin계 및 뽕나무뿌리로 염색한 견포의 색채는 연한 다색계통이었으며 염색견포에 황산동 및 황산제일철로 매염처리하면 색상(Hue)은 염재의 종류에 따라 각각 다르게 변화되었고 명도 및 채도(V/V)는 모두 감소되었다. 2. Tannin계 및 뽕나무뿌리로 염색한 견포에 황산동 및 황산제일철로 매염처리하면 미매염견에 비하여 세탁견도가 1급내외 향상되었고 매염처리견의 자외선조사에 의한 dye-loss율이 미매염처리 견보다 크게 감소되어 내광견도가 향상되었다.
