This study was carried out to evaluate the quality characteristics of Takju, Yakju, Spirit made by various cereal Nuruks which were made by Jokuk(whole wheat), Bunkuk(wheat flour), Maekkuk(whole barley). pH, Brix, cell number of yeast, alcohol content, flavors, organic acid, and sensory evaluation of brews were employed to analyze current study. Results showed that pH value of brews during fermentation decreased, while Brix value increased. In addition, alcohol contents increased up to 11 day's fermentation, but there were no significant differences among Jokuk, Bunkuk and Maekkuk(p<0.05). Cell numbers of yeast dramatically increased up to 5 day's fermentation, and then decreased. After 13 day's fermentation cell numbers of yeast were similar among Jokuk, Bunkuk and Maekkuk. In terms of analysis of flavor components, acetone and n-amyl alcohol were not detected in all brews, however fusel oil level was 494.65 mg/L in Maekkuk, and 525.4 mg/L in Bunkuk. Lactic acid showed the highest level in organic acid analysis. Furthermore, Jokuk and Maekkuk showed highest score in Takju, Maekkuk showed highest score in Yakju in sensory evaluation, although Jokuk, Bunkuk, and Maekkuk revealed similar score in spirit.

The developmental period(mean $\pm$ SE) of the red flour beetle, Tribolium castaneum was studied on brown rice at four constant temperature(25, 28, 34, $36^{\circ}C$ $\pm$ $0.5^{\circ}C$, RH 70%)conditions. Based on the results, the lower and the upper developmental threshold temperature for the beetle were also estimated. The duration of the egg stage was estimated to be 7.6 $\pm$ 0.25, 4.8 $\pm$ 0.10, 3.0 $\pm$ 0.03 and 2.5 $\pm$ 0.09 days at 25, 28, 34, $36^{\circ}C$, respectively. That of the larval stage was estimated to be 53.3 $\pm$ 1.49, 33.4 $\pm$ 0.57, 30.6 $\pm$ 0.70, 31.0 $\pm$ 1.18; that of the pupal stage to be 12.1 $\pm$ 0.17, 7.8 $\pm$ 0.09, 5.7 $\pm$ 0.09, 5.0 $\pm$ 0.07 ; that of the overall period which spans from eggs to the adult emergence to be 72.3 $\pm$ 1.67, 46.0 $\pm$ 0.55, 39.4 $\pm$ 0.64, 38.7 $\pm$ 1.15 days at 25, 28, 34, $36^{\circ}C$, respectively. The duration of the egg and the pupal stage were similar to those of the results reared on other diets such as wheat and maize. Fed on brown rice, however, the duration of the larval stage was significantly retarded than on wheat. The mortality of the beetle during ,development was higher on brown rice than on wheat reported, indicating that brown rice is a poor diet compared with wheat. The lower developmental threshold temperature was estimated to be $20.0^{\circ}C$ for all stages of the beetle. The upper one was estimated to be $40.2^{\circ}C$ for the overall stage. The modal value of the moulting times during the larval stage was 7. However, as temperature increased,.the frequency of the beetle that moulted more than 7 times became higher. The sex ratio of the beetle was not affected by temperature.

For the utilization of seaweed (Capsosiphon fulvecense, algae) powder as an ingredient of bread, the quality of bread made with different concentration of seaweed powder was evaluated with physical and sensory properties. The powdered algae was shown to have crude protein content at 25.38%. The major minerals were identified with calcium with 8.38 g/kg, potassium with 9.5 g/kg, and magnesium with 5.6 g/kg, which comprised to 19.08% of total mineral content. Amount of essential amino acids content was estimated to be 835 mg/100 g. Content of essential fatty acid was found to be 27,25% of total fatty acids. For the preparation of bread added with seaweed powder, the addition ratio of seaweed was set at 3, 5 and 7% versus wheat flour with same ratio of other ingredients. L value, lightness of bread, was proportionally reduced with increse of seaweed powder. However, b value, yellowness, was increased with the addition of the seaweed powder. Adhesiveness, cohesiveness, and springiness of the bread were reduced with the addition of the seaweed powder, however, hardness of the bread was vice versa. Texture, flavor, color, and overall acceptance of the bread added seaweed powder were shown up significant differences among all tested groups (P < 0.001), that is, more seaweed powder showed less favorable texture, flavor, color, and overall acceptance. Although the bread added with seaweed powder showed a less preference compared to control group, the bread with 3% of seaweed powder was favorable to other test groups, which might have a potential for the commercialization of functional breads using seaweeds.

This study investigated the quality characteristics and antioxidant activities of wet noodles as well as their cooking properties following the addition of peanut sprout extract (PSE) and powder (PSP), which are known to contain a significant level of resveratrol. Wet noodles were prepared with 0, 2.5, 5, 7.5 and 10% PSE and PSP. Quality characteristics such as increasing volume of noodle, water ratio, turbidity of cooking water and color, texture, and sensory evaluation were then assessed. Additionally, the total resveratrol content in the cooked noodles was analyzed by HPLC and DPPH free radical scavenging capacity. As the amount of PSE and PSP increased, the L value of wet and cooked noodles significantly decreased, whereas the a and b values increased (p<0.001). The L value of cooked noodles was significantly lower compared to wet noodles (p<0.001) whereas the a and b values were higher. For the cutting intensity properties of the cooked noodles, hardness was reduced with increasing amounts of PSE (p<0.001), and was significantly increased in proportion to the amount of PSP (p<0.05). Meanwhile, springiness was not significantly different in all groups. Total resveratrol content and free radical scavenging activity significantly increased in proportion to the amounts of PSE and PSP (p<0.001), especially in noodles containing 5%, 7.5% and 10% PSE and PSP. Finally, sensory evaluation of PSE noodle revealed that color, flavour, taste were significantly decreased (p<0.05). But there was no difference in overall acceptance among cooked noodles with 2.5% to 5% PSE comparison to the control. Sensory characteristics in the PSP noodle showed similar results. In conclusion, these findings suggest that peanut sprout extract and powder could be potentially used as functional food ingredients. In addition, up to 5% PSE and PSP can be substituted for wheat flour.

A 10-week feeding trial was carried out to investigate the feasibility of using spent coffee ground (CG) as a potential feed ingredient for olive flounder. Growth, feed utilization, body composition and antioxidant enzyme activity were examined. A control diet was formulated and three other diets were prepared to contain 5, 10 or 15% CG (designated as Con, CG5, CG10 and CG15, respectively) by replacing for wheat flour. Two hundred forty fish ($104{\pm}0.7g/fish$) were allotted to 12 circular tanks of 400 L capacity at a density of 20 fish per tank and fed the experimental diets twice daily. At the end of the feeding trial, fish fed the CG5 diet exhibited significantly (P < 0.05) higher growth performance than those fed the control diet. Also, fish fed the CG10 diet had a comparable growth to that of the control group, but further increase of dietary CG inclusion level to 15% resulted in significant decrease of growth performance. Fish fed the CG15 diet showed significantly lower feed efficiency and protein efficiency ratio than other treatments. Significantly lower muscle protein content was observed in fish fed CG15 diet compared to the control. Significant reduction in plasma cholesterol concentration was found in fish fed CG15 diet compared to control. No significant changes were found in alkyle and superoxide radicals scavenging activities of plasma, muscle and liver among dietary treatments. Also, liver total protein, total antioxidant capacity, catalase and glutathione peroxidase activities were not significantly influenced by dietary inclusion of CG. According to these results, we concluded that CG can be included up to 10% in the diet for olive flounder without any adverse effects on growth, feed utilization and antioxidant enzyme activity.

The purpose of this study is to look into dressing practices at the Woinarodo region in terms of ordinary and ritual clothes. Men wore Bqji(trousers) and Jeokori(jackets) as their plain clothes and sometimes Jangsam mid Durumaki(topcoat). During the period of Japanese colony, men wore Western-style clothes. For women it was basic to wear Chima(skirts) and Jeokori. And they preferred Momppe rather when in Japanese rule. In arrangements for their head, men put on gut, and had their hair cut during Japanese nile. Women laid a bundle of their braided hairs on the head or braided their hair, while married women did their hair up in a chignon during the ruling period People of the region put on straw and leather shoes, and then rubber ones since the late 1930s. Hand weaving was a major means of living for women at the region. Ramie, hemp and cotton were mainly weaved by hand. Starching was applied mainly to ramie and cotton. Glues for starching were made of raw rices, cooked rices, wheat flour or gloiopeltis tenax. For ritual clothes, especially in wedding, bridegrooms arranged themselves with Samokwandae and then Put on Baji, Jeokori, Durumaki and Danryung. But they Put on Western-style dresses as the liners of Danryung, and wear Nambawi Rather than the Samo after korean independence from Japanese rule. Bridges wore Chima, Jeokori and Wonsam and Chokdoori and covered their face with Hansam Wonsam did not be worn any longer after Korean independence from the rule. Shrouds for funeral ceremony were manufactured with silks, cotton and hemp, when the chief mourner wore hempen hoods and funeral robes, while women, Chima, made of hemp. and any type of Jeokori.

A feeding trial was carried out to investigate the effect of various fish meals as dietary protein source on growth, feed utilization and body composition of Juvenile flounder. Ten experimental diets were prepared to contain different fish meals: 4 kinds of white fish meal (WM-1, 2, 3, 4), 3 kinds of herring meal (HM-1, 2, 3), mackerel meal (MM), WM mixture and HM+MM mixture. Dietary energy and protein levels were designed to be isocaloric ($3.8 kcal g^{-1}diet$) and isonitrogenous ($46\%$) by adjusting the levels of fish meal, wheat flour and squid liver oil. Three replicate groups of fish (initial mean weight: 11.1 g) were hand-fed to visual satiety two times daily for 7 weeks. Survival was not significantly different among all groups. Weight gain of fish fed the HM-1 and HM-3 diets was the highest, but not significantly different from that of fish fed the either WM-2 or HM+MM diets. The lowest weight gain was found in fish fed the W-1 and WM-3 diets. Feed efficiency and protein efficiency ratio of fish fed the WM-2, HM-1, HH-3, MM and HM+MM diets were significantly higher than those of fish fed other diets. Daily feed intake of fish fed the WM-3 diet was highest, but not significantly different from that oi fish fed the either WM-4 or WMM diet. Significant differences were found in contents of moisture, crude protein, crude lipid and ash of whole body of fish. The results of this study indicated that growth of flounder can be affected by dietary fish meal source and quality, and WM-2, HM-1, HM-3 and HM+MM mixture are considered as useful dietary fish meal sources under these experimental conditions.
