The tradition of vocal music made from epic stories is commonly found in both illiterate and literate societies in the world. However. the epic musics of the literate societies have been widely favoured by the academics for their interesting topics. One of them. p ansori (representative Korean epic song) has largely been attracted by a number of researchers and been studied in terms of a variety of angles and approaches. This paper is not based on a new research on p ansori. but it attempts to reconsider its values at the wider range of contexts with which a comparison can be made. I have chosen four representative epic musics such as Punlaku of Choruli (songs and stories performed during Japanese puppet play). Wayang (Indonesian dance and drama), Gusle music (Yugoslavian epic music with the accompaniment of the gusle) and the music performed by Jali (Gambian secular musician) in order to understand their individual characteristics of the genre. The approach is based on the observation of their performances rather than looking in their historical sources. My findings derive from the fact that there are differences and similarities among these individual narrative musics in a number of aspects. For instance, the p ansori itself is considered as uniquely Korean and traditional. but it also possesses universal qualities which are widely shared with the same genres. The focus of the studies of p ansori on its unique aspects is certainly valuable. However, at the same time. I would argue that it needs a redefinition in terms of universality, thus identifying p ansori in the world perspectives of epic songs.

This study was conducted to explore the quality characteristics of colored rice depending on the cultivars (Jeogjinu, Josaengheugchal, Joeunheukmi, Heukjinjubyeo, Hongjinju, Heukjinmi, Geongganghongmi) for porridge. The moisture, crude protein, lipid, ash, amylose and damaged starch contents of colored rice ranged from 10.05~11.23%, 7.72~8.69%, 2.68~3.26%, 1.62~1.88%, 6.29~20.31% and 5.06~8.26%, respectively. The highest moisture (11.23%), crude protein (8.69%), lipid (3.26%) and ash (1.88%) contents of colored rice were detected in Heukjinjubyeo, Joeunheukmi, Josaengheugchal and Heukjinmi, respectively. The lowest amylose and damaged starch contents of colored rice were detected in Josaengheugchal and Joeunheukmi, respectively. In general, the water binding capacity, water solubility and swelling power of Heukjinmi were greater than those of the other cultivars. The investigation of the pasting properties (peak, trough, break down, final and setback viscosity, peak time, pasting temperature) of colored rice indicated a low value in Josaengheugchal. The lowest hardness (13,673.25 g) of colored rice was observed in Heukjinjubyeo while the highest digestibility (5.44 glucose mg/g) of colored rice was observed in Josaengheugchal. These results indicated that Josaengheugchal are suitable cultivars for porridge.

The objective of this study was to evaluate quality properties of high quality rice. Seven rice varieties, Dabo, Daebo, Samkwang, Sindongjin, Sukwang, Jinsumi, and Haiami, were investigated for proximate contents and physicochemical characteristics. Moisture content was highest in the Jinsumi (13.13%). Protein and lipid content was highest in the Haiami. The amylose content of the rice cultivars was 20.15~22.51%. The degree of amylopectin polymerization (DP) was analyzed, and in all cultivars, DP 13-24 content was found to be highest, at more than 53%, whereas DP ${\geq}37$ content was lowest, at less than 5.81%. With regard to free sugar, maltose content in rice was the highest (${\geq}46%$). Toyo value of rice was highest in Samkwang, Daebo, and Jimsumi. Palatability characteristics were highest in Daebo and Jimsumi. Thus, the results of this study suggested that Samkwang, Daebo, and Jinsumi can be effectively used as processed cooked rice, though further studies should be required regarding changes in the quality of rice after cooking.

용도별 동부가루 품질평가 기준 설정을 위한 일환으로 발아와 볶음처리 후 동부가루의 품질과 이화학적 특성을 분석한 결과 발아 및 볶음처리에 따른 동부가루의 수분 함량은 볶음 온도와 시간에 따라 유의적으로 감소하였으며, 조회분, 조단백질 및 조지방 함량은 유의적으로 약간 증가하였으나 큰 차이가 없었다. 발아시키지 않은 동부와 발아시킨 동부로 제조한 볶음 동부가루의 수분결합력은 볶음 온도와 시간에 따라 유의적으로 증가하였고 용해도와 팽윤력은 감소하였다. 볶음 동부가루의 명도는 볶음 온도와 시간에 따라 유의적으로 감소하였고, 적색도와 황색도는 증가하였다. 발아시키지 않은 볶음 동부가루와 발아시킨 볶음 동부가루의 총 폴리페놀 함량은 각각 4.27~6.17 및 2.84~4.83 mg GAE/g, 총 플라보노이드 함량은 각각 3.22~4.67 및 2.47~3.07 mg CE/g으로 볶음 온도와 시간이 증가함에 따라 증가하였다. DPPH 라디칼 소거 활성은 각각 272.14~460.47 및 198.04~344.10 mg TE/100 g, ABTS 라디칼 소거 활성은 각각 367.71~531.35 및 219.93~416.30 mg TE/100 g으로 볶음 온도와 시간이 증가함에 따라 활성이 증가하였다. 이상의 결과에서 볶음 동부가루의 품질 및 항산화 특성을 고려하여 고물이나 앙금 등 용도별 품질평가 기준 설정이 필요할 것으로 생각된다. The change in quality and physicochemical characteristics of cowpea flour after a germination and roasting treatment were evaluated. The moisture content of roasted cowpea flour decreased significantly with increasing roasting temperature and time, and the crude ash, protein, and fat contents increased. The water binding capacity of the roasted cowpea flour without and with germination increased significantly according to the roasting temperatures and times, but the water solubility index and swelling power decreased. The lightness of the roasted cowpea flour decreased significantly, and the redness and yellowness increased. The phenolic compounds and radical scavenging activity of the roasted cowpea flour increased with increasing roasting temperature and times. The total polyphenol contents of the roasted cowpea flour without and with germination were 4.27∼6.17 and 2.84∼4.83 mg gallic acid equivalents/g, respectively, and the total flavonoid contents were 3.22∼4.67 and 2.47∼3.07 mg catechin equivalents/g, respectively. The 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity of roasted cowpea flour without and with germination was 272.14∼460.47 and 198.04∼344.10 mg Trolox equivalent (TE)/100 g, respectively, and the 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity was 367.71∼531.35 and 219.93∼416.30 mg TE/100 g, respectively. Therefore, it is necessary to set quality standards for each application considering the quality and antioxidant properties of roasted cowpea flour.

쌀보리를 식품 및 공중보건산업에서 기능성 소재로서의 활용가능성을 알아보고자 쌀보리 품종(새찰쌀, 흰찰쌀, 새쌀) 및 도정률(95%, 85%, 75%)에 따른 항산화 및 tyrosinase 저해 활성을 평가하였다. 각각의 시료를 70% 에탄올에 1:10의 비율로 48시간 추출하여 여과 후 동결건조 하여 실험에 사용하였다. 95% 도정률을 기준으로 한 쌀보리 추출물의 DPPH 라디칼 소거능이 각각 5.90, 4.63 및 17.57 mg TE/g sample로 나타났으며, FRAP 값을 측정한 결과 새쌀보리 추출물이 1,041.53 μM로 가장 높은 환원력을 가지는 것으로 확인되었다. 새찰쌀, 흰찰쌀 및 새쌀보리 추출물의 tyrosinase 저해 활성이 각각 30.64, 38.62 및 60.64%로 새쌀보리 추출물이 가장 높은 활성을 보였다. 총 폴리페놀 함량 측정 결과 새쌀보리 추출물은 172.51 μg GAE/g sample, 새찰쌀보리 48.87 μg GAE/g sample, 흰찰쌀보리 44.58 μg GAE/g sample로 높은 수치를 나타냈으며, 품종 및 도정률에 따른 플라보노이드 함량 측정 결과 총 폴리페놀 함량 결과와 경향이 동일하게 나타났다. 쌀보리의 도정률이 증가할수록 맥강에 함유되어 있는 폴리페놀 및 플라보노이드 등과 같은 기능성분이 제거됨에 따라 항산화 및 미백 등의 생리활성에 영향을 미친 것으로 판단된다. 이상의 결과를 종합하여 볼 때 쌀보리의 품종 및 도정률에 따라 항산화 및 tyrosinase 저해 활성의 차이를 보였으며, 쌀보리를 이용한 기능성 제품의 개발에 있어서 중요한 기초자료로 활용될 수 있을 것이라고 판단된다. The purpose of this study was to evaluate the effects of barley cultivars [Saechalssalbori (SC), Huinchalssalbori (H), and Saessalbori (S)] and different milling recovery rates (95%, 85%, and 75%) on antioxidant and tyrosinase inhibitory activities. Results show that the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities of SC, H, and S extracts based on 95% coverage were 5.90, 4.63, and 17.57 mg Trolox equivalent/g sample, respectively. The ferric-reducing antioxidant potential (FRAP) value of S extract with 95% milling recovery was the highest at 1,041.53 μM. Tyrosinase inhibitory activities of SC, H, and S extracts were 30.64, 38.62, and 60.64%, respectively. Total polyphenol contents of SC, H, and S extracts based on 95% coverage were 48.87, 44.58, and 172.51 μg gallic acid equivalent/g sample, respectively. The total flavonoid content was highest in S extract with 95% milling recovery. The DPPH radical scavenging activity, FRAP value, tyrosinase inhibitory effect, total polyphenol, and flavonoid contents of barley extracts were reduced as milling recovery rate decreased. The results of this study suggest that milling recovery and cultivar of barley are important factors to improve the antioxidant and tyrosinase inhibitory activities of barley.

본 연구에서는 국내에서 육성된 조와 손가락조의 식품 및 공중보건산업 소재로서의 이용 다양화를 위한 기초자료를 확보하고자 작목 및 품종별 일반성분, 기능성분을 검정하고 에탄올 추출물을 이용하여 생리활성을 분석하였다. 일반성분 분석 결과 단아메가 조단백 함량이 다른 품종들에 비해 유의적으로 높았다. 무기성분 함량을 검토한 결과 칼륨은 삼다찰, 칼슘의 경우 손가락조인 핑거1호가 가장 높은 함량을 보였다. 기능성분 함량을 분석한 결과 손가락조인 핑거1호의 총 폴리페놀 함량이 30.64 mg/g으로 가장 높았고 피틴산은 단아메, 감마오리자놀은 황금이 유의적인 차이를 보이며 높았다. 항산화 활성의 경우 DPPH와 ABTS 라디칼 소거능, 그리고 FRAP 값 모두 핑거1호가 모든 조 품종에 비해 활성이 크게 높았음을 확인하였다. 효소저해 활성 결과에서는 핑거1호가 가장 높은 α-glucosidase 저해 활성을 보였으며, 다황메와 조황메는 다른 조 품종들에 비해 높은 tyrosine 저해 활성을 보였다. 이상의 결과를 종합해볼 때 손가락조인 핑거1호와 조는 다황메 및 조황메 등이 식품 및 공중보건산업 소재로서의 활용성이 높을 것으로 판단된다. 아울러 본 결과는 국내산 조와 손가락조를 식품 및 공중보건산업 소재로 활용하기 위한 기초자료로 활용이 가능할 것으로 생각되며 추후 각 활성에 대한 기능성분과 메커니즘 구명에 대한 연구가 지속적으로 요구된다. The purpose of this study was to investigate the physiological activities and the functional components of foxtail millet (FM, Setaria italica) and finger millet (FGM, Elusine coracana). Nine cultivars of FM (namely Keongkwan 1ho (KK1), Keongkwan 2ho (KK2), Dahwangme (DHM), Daname (DAM), Samdamae (SDM), Samdachal (SDC), Chohwangme (CHM), Hwanggeum (HG), Hwangmeechal (HMC)) and one cultivar of FGM (namely Finger1ho (FG1)) were cultivated and compared with respect to their physicochemical characteristics. The calcium content of FG1 was 11.6 times higher than the average calcium content of the FM cultivars, while the potassium and phosphorus content of the FG1 was the lowest among all cultivars at 2,582 and 2,511 ppm, respectively. The cultivar with the highest total polyphenol content was FG1 at 30.64 ㎎/g. The cultivars with the highest phytic acid and γ-oryzanol content were DAM (1.13 g/100 g) and HG (2.05 ㎎/100 g), respectively. FG1 showed the best antioxidant activities with the highest level of DPPH, ABTS radical scavenging capacities, and FRAP at 23.98 mg Trolox equivalent (TE)/g sample, 17.14 ㎎ TE/g sample, and 216.82 mM, respectively. FG1 also showed the strongest α-glucosidase inhibition activity at 89.64%. The cultivars showing higher tyrosinase inhibition activities were DHM and CHM at 67.21% and 62.82%, respectively. From these results, it could be concluded that FG1 would be highly useful as a functional agent and a good source for nutrients such as calcium and total polyphenols.
