Various art trends of the 20th century that contributed to the creation and development of abstract art had showed the transition from the convention of mere representation of the object to the formative sensitivity emphasizing self-expression. Noticing that such trends had influenced the fashion industry to move toward a free and individualized style, this study attempts to express the formative way from the existing art to wear, especially, based on early 20th century paintings, 5 casual wears were made which applied korean materials and silhouettes that are functional, sample and show traditional korea beauty. The purpose of this study is to search for a solution to expand the world market by producing dresses utilizing our own tradition that can be distinguished in the global market and that derive inspiration from the formative of the sensitivity of the paintings during the first half of the 20th century. It also aims to let national economy as a high-added industry. The result of this study are as follows: First, the expression method and element of various styles of art such as Fauvism, Expressionism and Cubism, during the period of transition to abstract art, clearly presented the direction toward the artistic liberation and made possible a new formative artistic expression of dress in the early years of the 20th century. Their ideas inspired the dress designers of the time with a reformative and creative sense of fashion and have greatly contributed to the development of a new era of uniqueness and individuality. Second, the color and the simplicity of form of the early 20th century paintings are suitable fro utilizing a motive of functional dresses and express unique and concise modern beauty. Third, it was confirmed that utilizing our tradition in contemporary dress can be a significant method of creation in which the uniqueness and creativity of Korean dress can be expressed, distinguishing it on the global scene, as well as inspire the originality and pride of our culture. Fourth, a possibility has been discovered. It is the functionality and uniqueness of aesthetic expression technique of the contemporary arts that can contribute to the fashion of tomorrow, by searching a modern fashion which was affected by the past and also by taking a look at the trend of modern fashion as the same field as casula wear.

Cobalt aluminate ($CoAl_2O_4$) is a highly stable pigment with excellent resistance to light, weather, etc., which has resulted in widespread use as a ceramic pigment. Due to the unique optical characteristics, $CoAl_2O_4$ is generally used as a coloring agent to decorate porcelain products, glass, paints and plastics. Here, $CoAl_2O_4$ pigments were synthesized by polymerized complex method and solid state reaction. Then $CoAl_2O_4$ pigment were grinded using the attrition milling with 1 mm size zirconia ball for 3 hours. The attrition milling process was performed at the constant speed of 800 rpm and ball to powder weight ratio (BPR) was 100 : 1. The characteristics of synthesized pigment were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), particle size analyser (PSA) and CIE $L^*a^*b^*$. The XRD patterns of $CoAl_2O_4$ show single phase spinel structure. The particle size of $CoAl_2O_4$ measured by FE-SEM, TEM and PSA analysis was in the range of 100~200 nm. The blue color of obtained $CoAl_2O_4$ pigments could be confirmed through CIE $L^*a^*b^*$ measurement.

UV irradiation causes a variety of biologic effects on the skin. These effects can be devided to acute reactuons and chronic reacxtions by duration of UV irradiation. Acute reactions are erythema reaction, pigment reactions and changes in epidermal thickness. Among them erythema reaction is most common and conspicuous acute effects of the skin. Upon exposure to sun or artificial UV soures, a faint redness response of skin may begin. Larger exposure causes sunburn reaction which is exaggerated erythema reactionassociated with pain, swelling, vesicle and dulla. Extent and time course of erythema reaction depend upon several factors including wavelength and dose of UVR, skin conditions likeas skin type, site, color, temperature, humidity and environmental factors. Evaluation of erythema erythema induced by UV irradiation is difficult to quantify. Degree of redness of skin are usually estimated by subjective visual evaluation. The lowest exposure dose required to protuce erythema is called minimal erythema dose (mod). Repeated exposures of UVR result in photaging skin. In this condition we can see wrinkling, skin atrophy, dilated blood vessels and keratoses. In sensitive persons photocarcinogenesis is can Be developed on exposed area of skin. Recently skin canser is increasing now in our country. An effective public education and photopreventive method must be developed.

The purpose of this study was to investigate the fatty acid profiles in 18 soybean cultivars grown in Korea. A total of eleven fatty acids were identified in the sample set, which was comprised of myristic (C14:0), palmitic (C16:0), palmitoleic (C16:1, ${\omega}7$), stearic (C18:0), oleic (C18:1, ${\omega}9$), linoleic (C18:2, ${\omega}6$), linolenic (C18:3, ${\omega}3$), arachidic (C20:0), gondoic (C20:1, ${\omega}9$), behenic (C22:0), and lignoceric (C24:0) acids by gas-liquid chromatography with flame ionization detector (GC-FID). Based on their color, yellow-, black-, brown-, and green-colored cultivars were denoted. Correlation coefficients (r) between the nine major fatty acids identified (two trace fatty acids, myristic and palmitoleic, were not included in the study) were generated and revealed an inverse association between oleic and linoleic acids (r=-0.94, p<0.05), while stearic acid was positively correlated to arachidic acid (r=0.72, p<0.05). Principal component analysis (PCA) of the fatty acid data yielded four significant principal components (PCs; i.e., eigenvalues>1), which together account for 81.49% of the total variance in the data set; with PC1 contributing 28.16% of the total. Eigen analysis of the correlation matrix loadings of the four significant PCs revealed that PC1 was mainly contributed to by oleic, linoleic, and gondoic acids, PC2 by stearic, linolenic and arachidic acids, PC3 by behenic and lignoceric acids, and PC4 by palmitic acid. The score plots generated between PC1-PC2 and PC3-PC4 segregated soybean cultivars based on fatty acid composition.

An experiment was conducted to examine the performance and carcass characteristics of Hanwoo (Korean native beef cattle) heifers and the fatty acid composition of muscle tissues of the heifers when the animals fed diets containing four levels of dried wormwood (Artemisia sp.). For the experiment the animals were given a basal diet consisting of rice straw and concentrate mixed at 3:7 ratio (on DM basis). The treatments were designed as a completely randomized design with two feeding periods. Heifers were allotted in one of four dietary treatments, which were designed to progressively substitute dried wormwood for 0, 3, 5 and 10% of the rice straw in the basal diet. There was no difference in body weight gain throughout the entire period between the treatment groups. Feed conversion rate was improved (p<0.05) only by the 3% dried wormwood inclusion treatment compared with the basal treatment. Carcass weight, carcass yield and backfat thickness of all treatment groups were not altered by wormwood inclusion. The 5% dried wormwood inclusion significantly increased (p<0.05) the size of loin-eye area over the other treatments. The higher levels (5 and 10%) of dried wormwood inclusion resulted in the higher (p<0.05) water holding capacity (WHC) in loin than the lower levels (0 and 3%) of wormwood inclusion. The redness ($a^*$) and yellowness ($b^*$) values of meat color were significantly lower (p<0.05) in the top round muscle of heifers fed the diet containing 3% dried wormwood. There was a profound effect of the progressively increased intake of dried wormwood led to the linear increase of unsaturated fatty acid content and the linear decrease of saturated fatty acid content in the muscle tissues of Hanwoo heifers. It is concluded that the feeding diets containing dried wormwood substituted for equal weights of rice straw at 5% levels would be anticipated to provide better quality roughage for beef heifer production and economical benefits for beef cattle producers.

This experiment was conducted to develop control method for Bemisia tabaci (Gennadius) on eggplant using sticky trap method. According to the color of the sticky traps, the attractiveness of the B. tabaci was the highest in the yellow trap, followed by the green and orange. However, white, blue, red, black and green sticky traps have reduced attractiveness of B. tabaci. In order to improve the efficiency and attractiveness of sticky trap to the B. tabaci, the different kinds of sugars such as glucose, fructose, oligosaccharide, starch syrup and pure sugar were added to sticky traps respectively. However, the effect of B. tabaci attractiveness was low in starch syrup, pure sugar, and non-treated sticky traps. The attracting effect of B. tabaci was depending on the location of sticky trap. The highest value was obtained where sticky traps were located in the top of the eggplant, followed by 30 cm above from the top level. In addition, we were installed up to 40 sticky traps to determine the optimal amount of sticky traps to control B. tabaci in eggplant. When increasing the sticky traps, the number of adult and nymphs of B. tabaci were tended to be decreased significantly. This tendency was more effective in the latter stages than in the early stages. As the number of sticky traps increased, not only the growth rate of eggplant, leaf length, and stem diameter were to be better. But also number of fruits and product marketable value were increased at the early stage of growing as well. The study had proven that the sticky traps had an effect on increasing the yield at the early stage of growth, but the efficiency of controlling decreased due to the high density of B. tabaci of the next generation.

An analytical method of nine synthetic food colors in Korea, Japan, Joint FAO/WHO Expert Committee of Food Additives (JECFA), and USA were compared. Contents of water insoluble matter in synthetic food colors tested were not different by general test methods of various organs. Contents of chloride and sulfate salts in Food Green No.3, Food Red No.3, Food Blue No.2, and Food Yellow No.4 slightly differed in various methods, and but up to the standard, and general test methods of JECFA and USA needed far more time. For the measurement of arsenic contents in food colors, colorimetric method in Korea and Japan, and silver diethyldithiocarbamate colorimetric method in USA and JECFA were used, but the standards of them were different. Content of heavy metals was up to the standard, but the methods were used colorimetric method in Korea, atomic absorption method in Japan, and both methods in JECFA and USA.

The present study evaluated the difference in objective and subjective meat quality properties among the pure-breed boars of Duroc, Berkshire and Yorkshire. Ten longissimus lumborum (LD) muscles were collected from each breed after 24 h slaughtering. The breed type showed a significant effect on intramuscular fat content, moisture (p<0.01), pH, sarcoplasmic protein solubility and color (p<0.05), whereas cooking loss and Warner Blazer shear force (WBsf) did not differ among the breeds. The Yorkshire breed showed significant (p<0.05) lower sarcoplasmic protein solubility, pH and CIE $a^*$ value when compared with other breeds. The sensory panels identified Duroc as having greater overall acceptability and higher rating values than other breeds. The oleic acid content was significantly lower in the Berkshire (29.85 %) than in the Duroc (40.19 %) and Yorkshire breeds (38.18 %, p<0.05). The Yorkshire breed showed the most desirable ratio of polyunsaturated and saturated fatty acids (0.31) than the Berkshire (0.16) and Duroc breeds (0.15, p<0.05). 40 volatile compounds have been identified and quantified, while aldehydes were the most abundant among flavor substances. Aldehydes were negatively correlated with oleic acid content (p<0.05). Current data indicated that each breed had their own merits and deficiencies in terms of meat qualityThe Yorkshire breed showed a greater number of weak points. Furthermore, this study indicated that individual fat-driven flavor components were greatly influenced by fatty acid composition. The polyunsaturated fatty acids did not show any negative effects on meat flavor if cooked meats were consumed soon after cooking.

In recent years, printing paper with a function of information delivery and aesthetic value has attracted a great attention with increasing market demand for coated paper that is capable of high quality printing. The coated paper for inkjet printing with high-quality of photorealistic grades requires the coating layer with a good wettability and porous surface structure in order to improve the printability of ink. In this study, the coated paper was prepared using polyvinyl alcohol (PVA) and surface treated nano silica sol with silane coupling agent. It was confirmed that the coating layer with surface treated nano silica sol showed a uniform pore distribution and flat surface roughness. Glossiness of the prepared printing paper was similar to that of commercial high quality photo paper. Especially, the coated paper with surface treated nano silica sol showed improved printability with excellent roundness of the printed dot of ink. These results indicates that the coating layer with excellent wettability and uniform pore distribution can be formed by using the nano-silica particles with improved dispersibility through the surface treatment of the silane coupling agent.

Fluorescence in situ hybridization with chromosome-specific probe has been shown to be a valid and rapid method for detection of chromosome rearrangements induced by radiation. This method is useful for quantifying structural aberrations, expecially for stable ones, such as translocation and insertion, which are difficult to detect with conventional method in human lymphocyte. In order to apply FISH method for high dose biological dosimetry, chromosomal abberations by radiation at doses of 1, 3, 5, and 7Gy were analysed with whole chromosome-specific probes by human chromosome 1, 2 and 4 according to PAINT system. The frequencies of stable translocation per cell equivalent were 0.04, 0.33, 1.22, 2.62, and 5.58 for the lymphocyte exposed to 0, 1, 3, 5, and 7Gy, respectively, and those of dicentric were 0.00, 0.06, 0.52, 1.19 and 2.44, respectively. Significantly more translocation of t(Ab), a translocated chromosome with a piece of painted acentric matrial 'b' attached to unpainted piece containing centromere 'A', than reciprocal chromosome t(Ba) was observed. The frequencies of all type of chromosome rearrangements increased with dose. From above result, FISH seemed to be useful for radiation biodosimetry by which the frequencies of various types of stable aberrations in human lymphocyte can be observed more easily than by conventional method and so will improve our ability to perform meaningful biodosimetry.
