  • This study evaluated the functional components of barley bran with different particle sizes and cultivars (Dahan, Hinchalssalbori, Heukgwang, Huknuri, and Boseokchal). Barley bran divided into fractions I (<60 mesh), II (60~100 mesh), and III (>100 mesh) was collected as pearling by-products produced by an industrial process consisting of consecutive barley pearlers. Total ${\beta}-glucan$ contents of all cultivars were especially highest in fraction II. Total arabinoxylan was the highest in barley bran from Boseokchal in fraction II. Total polyphenol contents were the highest in bran from Boseokchal and Hinchalssal in fraction II, and contents ranged of 5.61~7.00 and 4.24~6.58, respectively. Total flavonoid contents of all cultivars were especially highest in fraction II. 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities ranged from 2.78~7.53 mg L-ascorbic acid (AA) eq/g and 2.24~4.83 mg AA eq/g, respectively. ABTS and DPPH radical scavenging activities were the highest in barley bran from Dahan in fraction II. In this study, fraction II showed enriched functional components and has the best particle size range for enriched antioxidant activities. These results provide useful data for selection of appropriate cultivars and particle size of bran to achieve high quality barley processing.

  • This study was designed to elucidate the effects of mugwort powder supplemented to high fat diets on blood components levels in rats. The levels of mugwort content in the experimental diets were divided into 12, 21, 28% and the fat levels in high fat diet was 30% of total caloie intake. Forty-nine male Sprague-Dawley rats weighing 72.5$\pm$0.3g were divided into group I(add mugwort during 8 weeks), group II(add during 4 weeks) andcontrol group. The results of this study were summarized as follows : 1. There were no difference in body weight gain and FER throughout eight weeks of experiment. The organ weights were somewhat higher in control group, but not significant. 2. The mugwort groups(I, II) were significantly higher than control group in RBC. This result showed that the mugwort affect the content of RBC. Author would like to conclude this result that the RBC content of experim-ental animal was affected by the iron in the mugwort. There were no difference among experimental groups in Hb, Hct. 3. It was noteworty that the concentration of serum glucose and triglyceride in the mugwort groups(I, II) was significantly lower than the control group. This result concluded that concentration of serum glucose and triglyceride which had become high by high fat diet were affected by the calcium or dietary fiber in the mugwort. There were no difference among experimental groups in albumin, total cho-lesterol, HDL-cholesterol.

  • NGC 2024 FIR 6 is a star formation site in Orion and may contain a hypercompact H II region, FIR 6c, and a low-mass protostar, FIR 6n. The FIR 6 region was observed in the water maser line at 22 GHz and the methanol class I maser lines at 44, 95, and 133 GHz, using KVN in the single-dish telescope mode. The water maser spectra displayed several velocity components and month-scale time variabilities. Most of the velocity components may be associated with FIR 6n while one component was associated with FIR 4, another young stellar object in the 22 GHz beam. A typical life time of the water-maser velocity-components is about 8 months. The components showed velocity fluctuations with a typical drift rate of about 0.01 km/s/day. The methanol class I masers were detected toward FIR 6. The methanol emission is confined within a narrow range around the systemic velocity of the FIR 6 cloud core. The methanol masers did not show a detectable time-variability. The methanol masers suggest the existence of shocks driven by either the expanding H II region of FIR 6c or the outflow of FIR 6n.

  • The finite element modeling of small female occupant for crash simulation is presented in this paper subsequently to the part I of articulated rigid body model. The limbs and internal components are additionally modeled by joining them to the articulated rigid body model for predicting the crash injuries such as bone fractures and joint dislocations. The behavioral characteristics of each limbs and internal components were validated against available cadaveric test results. Accordingly, the human model proposed in this paper could be utilized for the investigation of impact injury mechanism and further complement the lacking biofidelity of current crash dummy.

  • The propose of this study was to investigate the changes of available components in Chajogi (Perilla sikokiana B.) by different harvest periods. The Chajogi samples were divided into four groups by harvest period. The four groups were divided into I (harvesting sample at 14, July, 2005), II (harvesting sample at 25, July, 2005), III (harvesting sample at 15, Aug, 2005) and IV sample (harvesting sample at 2, Sept, 2005), and then analysed with regard to the content of proximate compositions, minerals, amino acids, perillaldehyde and anthocyanin. The contents of reducing sugar increased with increasing harvesting periods, while those of crude protein, crude lipid and total amino acids decreased for IV sample as compared to the other samples. The levels of heavy metals in all samples were not detected. The Zn, Fe and Mg contents of IV sample decreased sharply. The perilladehyde contents were 0.36%, 0.42% 0.45%, and 0.35% for I, II, III, and IV products, respectively. III sample as contented to the other samples was shown to have the highest anthocyanine content (1.21% in dry basis). In conclusion, the date of harvesting Chajogi affects the contents of available components.

  • Glycyrrhizin (GA) content in licorice was determined by a couple of methods using HPLC, respectively. In Method(I), GA content itself was determined from the licorice aqueous extract, while in Method (II) glycyrrhetinic acid (GHeA ; the aglicone of GA) content corresponding to the quantity of GA was measured from the chloroform extract of the hydrolyzed product of licorice aqueous extract. A reverse phase column Hibar Lichrosorb RP-18 (E. Merck) was used as the stationary phase. As the mobile phase MeOH: $H_{2}O$(0.05M-$NaH_{2}PO_{4}$)=58 : 42 solution in Method (I), and MeOH: $H_{2}O $: AcOH=78; 19: 3 solution in Method (II) were suitable, respectively. The value obtained by Method (II) appeared slightly higher than that by Method (I). The effect of some other herbal drugs on the assay of GA quantity in mixed sample was also observed in both above two methods. By Method (I) Cassiae Cortex, Rehmaniae Rhizoma, Paeoniae Radix, and Angelicae Radix gave the subtractive effect on the amount of GA compared with the value from licorice alone. In the case of Method (II) Cassiae Cortex and Rehmaniae Rhizoma appeared to have subtractive effect but Paeoniae Radix and Angelicae Radix scarcely showed any influence. Pachymae Fungus did not affect the GA content at all. It seems that glycyrrhizin in licorice interacts with certain components of other herbal drugs.

  • Streptomyces albus wild type ATCC 21838 produced salinomycin, polyether antibiotic. To clone genes related salinomycin production, a genomic library was screened using actI as a DNA hybridization probe. pWHM 210 was isolated, which contained an approximately 24 kb of insert DNA. A 3.8 kb region in the 24 kb insert DNA was hybridized to actI and the nucleotide sequence of this region was determinied. Two open reading frames found in the same direction were homologous to genes for $\beta$-keto acyl synthase/acyl transferase and chain length determining factor in type II PKS (polyketide synthase). The genes were components of minimal type II PKS genes, highly conserved and showed the strong simiarity to other type II PKS genes known today.

  • Mineral chemistry of talc from the Dongyang talc deposits was studied to characterize the differences between dolomite-origin talc (talc I) and tremolite-origin talc (talc II). Average iron and aluminum contents are higher in talc II, 2.18 wt% FeO and 0.31 wt% $Al_2$O$_3$), than in talc I, 1.48 wt% FeO and 0.08 wt% $Al_2$O$_3$). Consistently lower Mg/(Mg+Fe+Mn) ratios and higher AI concentrations with uniform values of talc II compared to talc I seem to reflect the compositional differences of the original materials, tremolite and dolomite, respectively. Relative enrichment of Al as well as Fe in talc II compared to tremolite can be attributed to their immobile behaviors during alteration process and the rapid diffusion of hydrothermal fluids, which can accelerate instantaneous nucleation with immaturity growth of talc II. Increase in the concentrations of talc II can lower the ore grade by increasing concentrations of impure components such as AI and Fe, and by abundant presence of tremolite as well.
