Bacillus amyloliquefaciens FSE-68 isolated from meju, a Korean soybean fermentation starter, was identified on the basis of biophysical tests and 16S rRNA gene sequence. A neutral metalloprotease (NPR68) and an alkaline serine-protease (APR68) were purified by ammonium sulfate precipitation and cation exchange chromatography and identified on the basis of(More)
Numerous attempts have been made to find the mechanism and component of the cholesterol lowering activity of soybean. In this study, it was proved that the peptides in soybean protein hydrolysate (SPH) made by certain proteases have a hypocholesterolemic effect. Among the mechanisms suggested, that is, blockage of bile acid and/or cholesterol absorption,(More)
Soybean protein and its hydrolysate have been reported to have cholesterol-lowering property, but the responsible components are still largely unknown. In previous study, we found that soybean protein hydrolysate (SPH) prepared with the protease from Bacillus amyloliquefaciens FSE-68, strongly stimulates transcription of low density lipoprotein receptor(More)
Rice bran protein (RBP) was prepared by alkali extraction and isoelectric precipitation from defatted rice bran. The protein quality of RPB was evaluated and compared to two vegetable proteins [soy protein (ISP) and rice endosperm protein (REP)] and two animal proteins [whey protein (WPI) and casein]. RPB contained 74.93% of protein and its pepsin(More)
The Korea Institute of Geoscience and Mineral Resources (KIGAM) and Kangwon National University (KNU) GB-SAR team have been developed a fully polarimetric and interferometric GB-SAR system over past several years. The main objective of this study is to analyse a polarimetric characteristics of various terrain targets measured by a polarimetric GB-SAR system(More)
In order to apply to land mine detection effectively, bistatic GPR using an optical electric field sensor as a receiver has been developed. The optical electric field sensor is very small and uses optical fiber instead of metallic coaxial cable. With the combination of these advantages and the bistatic radar system, it can be possible for an operator to(More)
This paper presents the variation of the radar backscattering of intertidal mudflats in the west coast of Korea observed by Radarsat-1 synthetic aperture radar (SAR) images and investigates the related factors by an indoor experiment and a field experiment using a ground-based C-band scatterometer. The 15 Radarsat-1 SAR images of the intertidal mudflat near(More)
The main objective of this study is to analyse the polarimetric characteristics of the various terrain targets by ground-based polarimetric SAR system and to confirm the compatible and effective polarimetric analysis method to reveal the polarization properties of different terrain targets by the GB-SAR. The fully polarimetric GB-SAR data with HH, HV, VH,(More)
We made a ground-based synthetic aperture radar (GBSAR) system and tested its interferometric SAR (InSAR) measurement on the displacement of a trihedral corner reflector with atmospheric correction in terms of humidity and range. The GB-SAR worked at C-band with the synthetic aperture length of 5 m. Fully-polarimetric images were obtained with resolutions(More)
This paper presents the development of a ground-based arc-scanning synthetic aperture radar (ArcSAR) system mounted on a truck. ArcSAR formulates synthetic aperture by a horizontal circular motion of antennas attached at the end of an extendable boom. The ArcSAR system is designed to operate in two different imaging modes: the spot mode and the scan mode.(More)
