This study was conducted the physicochemical and sensory characteristics of fish paste with yam powder(0~5%). The pH of the samples ranged from 6.89 to 7.02, and moisture content ranged from 79.53 to 80.44%. Increasing the amount of yam powder in the fish paste tended to decrease the lightness(L) in Hunter color value while increasing the redness(a) and yellowness(b). For the textural characteristics, the addition of yam powder increased strength, gumminess, cohesiveness and springiness. Fish paste with 3~5% yam powder had good flexibility and wasn't broken even after 4 times folds. In sensory evaluation, the addition of 2% yam powder had the best score in color, taste and overall preference. Therefore, this results suggest that 2% yam powder can be applied to fish paste for the purpose of high quality, preference and functionality.

This paper proposes an algorithm for odd, doubly even, and singly even magic squares. In constructing an odd magic square, de la $Loub{\grave{e}}re^{\prime}s$ method is widely known and used, but it has an inherent defect of executing $O(n^2)$ steps. 2 types of cross algorithms have been proposed to the double even magic square, and more to the singly even magic square based on the odd magic square of ${\frac{n}{2}}{\times}{\frac{n}{2}}$, the most popular and simple of which is one proposed by Strachey. The algorithm proposed in this paper successfully constructs odd and doubly even magic squares by undergoing 3 steps and 4 steps respectively. It also directly constructs a singly even magic square without having its basis on the odd magic square.

The characteristics of extracts and precipitates after extraction at different water temperature (25, 50, 75, 95℃), ethanol ratio (25, 50, 75, 100%), and extraction method (stir, soak, autoclave) of yam powder and raw yam were investigated. The total polyphenol content was the highest in the 50% ethanol extract of yam powder. The DPPH radical scavenging activity was the highest in the 75% ethanol extraction and the crude saponin content was the highest in the 95℃ water extraction. Tyrosinase inhibitory activity was the highest in 95℃ water extraction, low concentration of ethanol extraction, and autoclave extraction. The peak viscosity, trough, and final viscosity of the precipitates increased after ethanol extraction, whereas decreased after the 95℃ water extraction and the autoclave, indicating the destruction of starch granules. This was confirmed by observing the starch granules broken using the SEM. The significance of this study was to investigate the possibility of the use of yam resources as a material, processing product development, skin beauty functional food and cosmetic material.

The origin of Korean mime is traceable to sacred actions of prehistoric age. There are materials about mime of this age in the archeological materials of this age, oral literature/myth, and written literature about this age. There were traces of the most original form of mime in primitive ritual of tribal nation age. The mimes of Samkooksidae/Tree Nation Age of Korea were presented to forms of Kamoobekhee(歌舞百戱)/Sanakbekhee(散樂百戱). We can discover traces of mime of this age in Hosunmoo(胡旋舞), Gwangsumoo(廣袖舞), Kweraehee(傀儡戱), Keeak(伎樂), Kummoo(劍舞) Muaemoo(無㝵舞), and so forth. Especially, Keeak in Beckjae was mask mime of Buddhistic contents. We can recognize that secular theatres were more diversified and strengthened than sacred thaetres in Nambukgooksidae/South-north Nation Age. According to these changes, there were many changes in the mime of this age. We can concretely find traditions of mime of this age in Cheryongkamoo(處容歌舞), Hwangchanmoo(黃倡舞), Taemyun(大面), Wuljen(月顚), Sodok(束毒)', Sanyae (狻猊), and so forth. Mimes of Koreasidae/Korea Age take diverse forms of puppet play, mask play, dance play. Established traditional mimes as Cheryongkamoo(處容歌舞) were widely disseminated in society. And dance plays of mime form as Hunsundo(獻仙桃), Pokurak(抛毬樂), Yunhwadae(蓮花臺)' were imported from Song Nation of China. Mime of Chosundidae/Chosun Age were developed with changes of theatre that were divided into Kyusickjeehee[規式之戲] as Kwangdae(廣大), Ser-in(西人), Joojil(注叱), Rongryung(弄鈴), Kendoo(斤頭) and Sohakjihee[笑謔之戱] as Soochuk(水尺) Sengkwangdae(僧廣大). Styles of theatre in this age were specialized into mudangkuk, Pungmoolkut, Inhyunguk/Puppet play, Talnoree/Mask paly, Pansori, Kungjoong Kamuakguk. According to this changes, mime of this age were specialized into diverse aspects. Korean mime were specialized into Kutnorum-formed mime, Inhyungnorum-formed mime, Jabsaeknorum-formed mime, Talnorum-formed mime, Kungjoongmuyong-formed mime, Pansori-formed mime, and so forth.

The purpose of this study was to investigate the effects of adding various concentration of yam powder (Y0:0g, Y1:2g, Y2:4g, Y3:6g, Y4:8g, Y5:10g) on the physicochemical and sensory characteristics of jelly. The pH of the samples ranged from 5.61 to 5.70, and this pH range was stable. As for the viscosity of the jelly, the samples made with yam powder showed higher viscosities than the control. and the viscosity increased with increasing amounts of yam powder, viscosity was increased. The Hunter color L- and a-values decreased significantly (p<.001) by the addition of yam powder. For the textural characteristics, the addition of yam powder increased the cohesiveness and decreased the springiness and chewiness. In the sensory evaluation, the appearance and flavor acceptability of the jellies were in the order of Y0>Y1>Y2>Y3>Y4>Y5. The texture acceptability was highest in Y0 and Y1 and taste and overall acceptability were highest in Y1.

The objective of this study was to determine the proximate composition and antioxidant activities of Dioscorea spp. Samples were divided into Dunggeunma (D. bulbifra L), Danma (D. polystachya Turcz), Jangma (D. batatas Decaisne) and Danpungma (D. quinqueloba Thunb). The samples were extracted with 70% ethanol and analyzed for total flavonoid contents, polyphenol contents, DPPH radical scavenging activity, and ABTS radical scavenging activity. The moisture contents ranged from 11.96% to 15.01%. The crude protein contents were in the range of 7.86% to 11.55% (Dunggeunma 11.55%, Danpungma 10.48%, Danma 9.43%, Jangma 7.86%). The crude fat contents were between 0.37% and 0.43% (Danpungma 0.43%, Jangma 0.37%, Dunggeunma 0.37%, Danma 0.37%). In the antioxidant activities assay, total polyphenol content of Danma was significantly higher than those of other species at 115.47 mg/100 g gallic acid equivalent (GAE) (p<0.05), whereas it was significantly lowest in Jangma at 66.31 mg/100 g gallic acid equivalent (GAE) (p<0.05). ABTS and DPPH radical scavenging activities of Danma were significantly highest at 104.43 and 56.72 mg trolox eq/100 g (p<0.05). Therefore, antioxidant activities of Dioscorea spp. provide a possible scientific basis for assessing the performance of functional material of Dioscorea spp.
