In this study, the nuances of salicus flexus resupinus were composed using the break of neuma suggested by Dom Euge´ne Cardine. As a result, 19 cases available out of the total 31 nuances could be found in manuscript St. Gall, one of the chironomic neuma system. When they were analyzed, it was found that each desirable nuance could be created through the break of neuma, and particularly, the tones, which the effect of neumatic break took place, were always such as finalis, dominant and mode relative in their modes. It was also disclosed through this study that nuances of more diverse rhythms could be created by expanding the tones before or alter neuma which was composed. Such results may suggest that the nuance composition using the effects of the neumatic break would be applied to express the nuances of certain or desired rhythms and therefore, that it would possibly contribute to the precise revival for performance and melodic analysis of Gregorian chant.

This study was performed to evaluate the possibility of application of lactic acid bacteria fermentation to increase the anti-allergic activity of the extracts from Houttuynia cordata Thunb. H. cordata Thunb was fermented on 25, 30, 35 and 40℃ for 5 days by two species of lactic acid bacteria, Leuconostoc mesenteroides 4395 and Lactobacillus sakei 383. The anti-allergic activity of water extracts of H. cordata Thunb was then analyzed both before and after fermentation. Anti-allergic activity was determined in vitro assays by using 5-lipoxygenase (5-LO), cyclooxygenase-2 (COX-2) and β-hexoseaminidase release of RBL-2H3 cells (degranulation marker). The extracts fermented at 35℃ by both bacteria had the highest inhibitory activities against 5-LO, and also higher than the control, and the one fermented at 30℃ by both bacteria had the highest inhibitory activity against COX-2. The degranulation of RBL-2H3 cells induced by IgE-antigen complex was estimated as β-hexoseaminidase release rate as reference of 100%, the release rates were inhibited in 25 μg/ml of the extracts fermented at 30, 35 and 40℃ only by L. mesenteroides 4395. These results indicate that anti-allergic activity of H. cordata Thunb is increased by lactic acid bacteria fermentation.

미국이나 일본 같은 외국의 사례와는 달리, 한국에서는 음식물 분쇄기의 사용이 법적으로 허용되지 않고 있다. 음식물 쓰레기의 성상과 특징상 다른 종류의 그것과는 그것을 일일이 분류하여 일정한 장소에 갖다놓고 수거하는 것에 대한 번거로움과 어려움이 있다는 것은 주지의 사실이다. 또한 많은 사람들이 해외에서 합법적으로 사용되고 있는 주방용 오물분쇄기의 합법화를 원하고 있는 실정이다. 본 연구는 2007년도에 이루어진 가정용 오물분쇄기의 도입에 대한 제주지역 주민들을 대상으로 실시한 설문 분석을 토대로 WTP를 추정하고 이에 영향을 끼치는 요인을 분석한다. 나아가 본 분석을 토대로 현재까지도 논의중에 있는 우물분쇄기 전면허용에 대한 함의점을 찾고 정책적 시사점을 제공 하는 것이다. 제주시의 사례에서 나타난 바는 응답자의 WIP가 초기 제시가격이 높고 환경친화성향이 강할수록 높았으며 비용편익비율이 1.09로 나타났다.
