This research provide a general model for viscosity curve. The rheological behavior of cement-based materials has been described by a flow curve. The flow curve helps intuitive understanding to explaining the flow of concrete. However, in this study, the rheological behavior of cement paste was analyzed using different approach called the viscosity curve. In this study, Sisko model for viscosity curve is used to indicate the rheological behavior of cement paste. Also relaxation process is analyzed by exponential model.

Rice is the most important crop as the staple food and two priorities in rice production are high yield and good quality in Korea. Far more improvements in grain quality, especially eating quality are required to meet the demand of consumers in rice producing areas. In the study presented here, a recombinant inbred lines (RILs) population derived from a cross between a temperate japonica and a tropical japonica and its genetic linkage map were employed to locate the QTL locus underlying six parameters of RVA profiles. Out of six RVA profile parameters, two characteristics, breakdown viscosity (BDV) and setback viscosity (SBV) are more correlated to eating quality of cooled rice. A total of four QTLs for two RVA profile parameters were identified. Two QTLs, qBDV-6 and qBDV-9 for BDV were detected on chromosomes 6 and 9. These QTLs increased the BDV by 26.2 and 16.4 from Ilpumbyeo allele, respectively. A QTL, qBDV-6 in the interval RM540-RM587 of the wx gene on chromosome 6 was reacted as a major QTL which could explain 26.2% of the total phenotypic variation. A QTL, qBDV-9 in the interval RM5688-RM444 explained 7% of the total variation as a minor QTL. Two QTLs, qSBV-6 and qSBV-9 for SBV also identified at the same region with QTLs of BDV on chromosomes 6 and 9. A QTL, qSBV-6 in the interval of the wx gene on chromosome 6 could explain 24.4% of the total phenotypic variation. A QTL, qSBV-9 in the interval RM5688-RM444 explained 8.2% of the total variation. These QTL region on chromosomes 6 and 9 would be use as useful marker to select elite lines of good eating quality in early generations in japonica rice breeding.

천연색소를 함유한 유색식물체 분말(울금, 복분자, 백련초, 홍피망, 녹차, 단호박, 뽕잎)과 찹쌀분말에 1, 3, 5% 첨가하여 호화시켜 L. lactis 젖산균으로 배양한 약초부각용 발효 찹쌀풀의 품질특성을 조사하였다. 총당과 환원당은 젖산균으로 발효시킨 발효찹쌀풀이 대조구인 생찹쌀풀에 비하여 높은 경향이었다. 총산도는 유색식물체 분말농도를 증가시킨 젖산균 발효풀에서 점진적으로 증가되었는데, 단호박(), 홍피망()에서 배 크게 나타났다. 점도는
