The purpose of this study is to obtain the symbolic meaning of the priestly costume through the Bible. Based on corroborative the Bible, this thesis analyzes the costume of priest. This compares the two onyx stones on the shoulder pieces with four rows of precious stones on the breastpiece. This era falls on about from the 15th century before Christ. It was found that the breastpiece was a piece of the same multicolored linen as in the ephod, a span square when folded double. It symbolizes righteousness. It hung on the high priest's chest, supported by two golden chains attached to the shoulder clasps. It symbolizes love. On the breastpiece were twelve beautiful jewels, arranged in four rows of three jewels, each jewel symbolizing one of the tribes of Israel. The variety of jewels on the breastpiece suggests the variety of people. Urim is the Hebrew word for 'lights' and therefore would logically be associated with bright or white stones. Thummim is the Hebrew word for 'perfection'. The high priest's ephod was made of gold, and of blue, purple, and scarlet yam, and of finely twisted linen. The golden yam symbolizes faith. The robe of the ephod was made entirely of blue cloth. The blue color symbolizes an obligation and life. The robe of the ephod symbolizes calling and dignity. The woven tunic symbolizes holy duty.

This experiment was conducted to determine effects of trenching depth on characteristics and yield of tubers in Chinese yam (Dioscorea opposita Thunb). Self-propelled trencher, ‘NF-827H’ produced by KAWABE company, was used for trenching. When trenched, tuber's length and weight were longer and heavier, tuber's shape was better, and marketable tuber yield was remarkably increased than those of conventional plowing and soil preparation by a tractor. The size and yield of tubers were greatly enhanced by trenching in long-tuber variety than that in short-tuber variety. The depth of trenching is recommended to be more than 60cm for short-tuber variety and more than 80cm for long-tuber variety considering the size, shape and yield of the tllbers.

This study was conducted to further characterize mucilages from Dioscoreae Rhizoma, which have been known to be proteoglycans. We chose the two types of yams, Dioscorea batatas Dec. (club-like) and D. japonica Thunb. (cane-like). Repeated gel filtration of a dialyzed water extract of each fresh yam on Bio-gel P-100 and then Sephadex G-150 columns completely separated the mucilage from protein. Furthermore, gel filtration of a water extract from each yam processed by steaming and drying on the Bio-gel P-100 column gave only one polysaccharide peak without protein. These results revealed that the mucilages of yams were only composed of polysaccharide. Then we assessed some properties of the mucilages under three kinds of criteria: a complex-forming capacity between mucilage and alcian blue, mannose content in the mucilage, and viscosity. The complex-forming capacities of two types of fresh yams were closely similar with each other, but the processing of two types of the fresh yams greatly lowered the complex-forming capacity and viscosity.

And also, the thermal insulation value of the bedding were measured by warmth retaining tester. In addition, this paper examines the influence of varying materials, structural factors and blanket layers on the thermal insulation effect of the bedding. The main results obtained from this study are as follow : 1. The design of lightweight blankets make an attempting with a varying materials and structural factors such as yam count, fabric densityarn. 2. Almost, the design of lightweight blankets for polyester/cotton blended blanket and down quilt make an attempting without reduction in thermal insulation values. 3. The 6 layers of blanket have less thermal insulation value than the 6 times of blanket for under a layer have. About 27~32% decrease is observed in thermal insulation value of blanket for under 6 layer. 4. The thermal insulation value and areal weight of blankets have a positive relation between the thermal insulation value(Y) and areal weight(X) is based on the following equation. wool blanket : Y = 1.0850X + 0.4188 (r = 0.9992) PIC blended blanket : Y = 0.8845X + 0.3034 (r = 0.9999)

The study was carried out to evaluate the affect of proton beam radiation on production of bulbil and tuber including change of endogenous gibberellins, of Dioscorea opposita Thunb. The yield of bulbils and tubers from non- and irradiated D. opposita Thunb at doses of 5, 10, 15 and 20 Gy were determined. Endogenous gibberellins were also quantified by GC/MS analysis. D. opposita tubers irradiated at 15 Gy produced higher bulbil production than non-irradiated plants. Enlarged bulbil (above size diameter 4 mm) was significantly increased at 15 Gy. Bioactive endogenous $GA_4$ was dominant in bulbils and tubers irradiated with proton beam rather than $GA_1$. Major gibberellins biosynthetic pathways in bulbils and tubers of D. opposita plants were non C-13 hydroxylation route. From the results of this study, 15 Gy proton beam radiation was suggested as an optimal dose that can produce high amounts of bulbil for mass production of D. opposita plant.

The 18th Winter Universiade will be held in Muju in 1997. It is a good opportunity to inform the local foods of Muju to the inside and outside of Korea. First of all, we carefully investigated the quantity of all kinds of food material, their circulation ability, and cookery per year in Muju. We found about sixty kinds of food as many as restaurant. We presented how to improve such kinds of food as O-Chunk (fish porridge), Minmulmaeuntang, Kochunaengi chungsik, etc. and how to use the special products of Muju such as yam, kochunaengi, wasabi and wild herb. The many kinds of cookery were specialized to cooks through manual and actual skills. And then we held a food contest that twenty-two cooks took part in the contest and there were exhibitted forty-two kinds of foods. Finally, through discussion and food contest, Muju Sanchae Bibimbap (meal which mixed rice with wild plants), Muju Sanchae chungsik (meal which has various wild plants with rice), Muju Kochunaengi Chungsik (meal which has various wild plants and wasabi with rice), Ma Naengmyun (cold yam noodle) and Muju Minmulmaeuntang (hot fish porridge) were recommended.

Excess use of chemical fertilizer causes soil acidification and accumulation of salt, and thus might bring to desertification of soil. To overcome this problem, it needs limited usage of chemical fertilizer and increased usage of natural fertilizer as an alternative. In this study, dry soil-borne Bacillus sp. SHL-3, which was isolated from arid and barren soil, with plant growth promoting activity was isolated for identification and to determine optimal culture condition. A bacterial strain SHL-3 had the IAA productivity ($5.16{\pm}0.10mg\;L^{-1}$), ACC deaminase activity ($0.36{\pm}0.09$ at 51 hours) and siderophore synthesis. It was identified as genus Bacillus sp.. Also, optimal culture condition of SHL-3 were $20^{\circ}C$ and pH 7 in LB medium. Bacillus sp. SHL-3 had up to 4% salt tolerance in the medium. We evaluated the plant growth promotion ability of SHL-3 using yam (Dioscorea japonica Thunb.). As a result, Bacillus sp. SHL-3 was effective on the increase of the shoot length (202.4% increase for 91 days). These results indicate that Bacillus sp. SHL-3 can serve as a promising microbial resource for the biofertilizers of soil.

Dimensional constants (k values) of single jersey fabrics made from $LincLITE^{(R)}$ and conventional yams are calculated under dry, steam, full relaxation treatments. Fabrics were made under different tightness factors such as high, medium and low with different twist factors, twist directions and feeder blending. $LincLITE^{(R)}$ yarns made to get soft and bulkier effects with yam count of 39 tex and conventional yams made into 39 tex and 48 tex yam counts. Various effects on K values are analysed using correlation coefficients. K-values are increased with relaxation progression and have shown some differences between in $LincLITE^{(R)}$ and conventional fabrics, and feeder blended fabrics. Loop shape factor is highly affected by tightness factor, relaxation and feeder blending in $LincLITE^{(R)}$ fabrics, whereas twist factor not significantly effects on loop shape factor in conventional fabrics. Stitch density significantly increases with relaxation in conventional fabrics and no significant effect shows with $LincLITE^{(R)}$ fabrics.

This study was carried out to investigate the quality characteristics of snow crab cream soup in order to seek the possibility of using fresh yams and potatoes instead of roux as thickening agents. The highest crude lipid(p<.05) and moisture(p<.001) were examined for the snow crab cream soup with yams and with potatoes as thickening agents($S_1$),($S_2$). The highest pH levels of $S_2(5.75)$ for the snow crab cream soup with yams and with potatoes were 75% and 25%. respectively. The highest lightness of 71.51(L value) was found in the 100% potato as a thickening agent($S_5$)(p<.001). The redness(a value) and yellowness(b value) were increased by adding potatoes to the snow crab soup(a=p<.001), (b=p<.01). Viscosity was increased by potato contents, and highest for the snow crab cream soup($S_5$) (p<.001). In sensory evaluation, the highest sensory scores for flavor and texture(p<.001) of mean 5.11 and 5.05, respectively, were obtained from the snow crab cream soup with yams(75%) and with potatoes(25%)($S_4$). The highest overall acceptability of mean 5.11 was found in the snow crab cream soup with yams(50%) and with potatoes(50%) as thickening agents($S_3$)(p<.001).
