  • This paper proposes the method to develop the fuel of suljigemi pellet using agricultural by-products the occurred during the manufacturing of alcohol. The goal of the development of suljigemi using biomass is to make the pellet fuel of high calorie. The suljigemi pellet is difficult to recycle waste in the manufacture company of alcohol. suljigemi pellet has the effect of zero emission as the soil conditioner using ash after burning. Also suljigemi pellet has the reduction effect of carriage fee, fuel economy and low-cost high-efficiency effects, environmentally clean fuel as CO2 emissions savings. So the technologies of the suljigemi fuel pellet are developing low carbon, green growth renewable energy fuel through futuristic energy system will be. In experiments, suljigemi pellets confirmed the calories by about 10% higher than wood pellets with the same conditions.

  • The catalytic effect of molybdovandophosphate heteropolyanion (HPAs) on the delignification of kraft bagasse pulp by hydrogen peroxide has been investigated. Very small amounts of the catalyst (0.05 0.3 mM/l) gave convenient results. Partial reduction of the catalyst was also studied. The effect of reaction medium (water, ethyl alcohol and acetone) on the bleaching was also studied. The results obtained show that the optimum condition for bleaching in presence of polyoxometalate were 0.05 mM/l catalyst concentration at $70^{\circ}C$ reaction temperature and $7\%$ consistency at pH 2 in aqueous medium. The ratio of water to solvent of 60:40 from acetone gives higher brightness than ethyl alcohol. The catalyst solution can be reused for 5 times without any reduction in brightness. ESR for the blank and exhausted solutions under different conditions was also carried out to find the relation between reduced metals and pulp brightness.

  • Effect of solution property on the weight varation and microstructural change of film was studied by electrophoretic deposition in order to obtain a homogeneous and dense zirconia film. As a result of weight kinetics of film which obtained in alcohol or aqueous solution having different polarity experimental data showed large deviation from theoretical ones calculated by Zhang's kinetic model. It had been shown that the weight affecting factors was largely dependent on properties other than dielectric constant and viscosity of solvent zeta potential appiled field and time. In initial stage a main factor of the drastic weight increase was the capillary drag of porous substrate. The cause of weight decrease with time in aqueous solution after 300 s was attributed to the defect of film by sagging and electrolytic reaction. The electrolyte film which prepared in alcohol solution with good wetting for substrate had better homogeneous and dense microstructure than one in aqueous solution with high surface tension.

  • Methanol extracts of five Berberidaceae species were examined against tissue factor inhibitory and tumour cell growth inhibitory activity. Methanol extracts of Berberis koreana Palibin showed a strong cytotoxicity activity against SK-MEL-2 (Melanoma) tumour cell lines with more than 90% in $25{\mu}g/m\ell$ and against A549 (Lung carcinoma), SK-OV-3 (Ovarian cancer), XF498 (CNS cancer) and HCTl5 (Colon cancer), other Berberidaceae species except B. koreana species have no effect on the tumour cells. Biologically active compound, therefore, was isolated through the activity guided fractionation and purification. The structure was confirmed by NMR. FT-IR and MS to 2-(3,4-dihydroxybenzyl)-ethyl alcohol. It showed cytotoxicity activity against SNU-C4 tumour cell lines with 50.7% in $50{\mu}g/m\ell$. Methanol extracts of 5 Berberidacae species have no effect on the tissue factor inhibitory activity.

  • This study was to evaluate the effect of isopropyl alcohol fraction of ultrasonication processed ginseng flower buds(GFB-IF) on the collagen synthesis activity and inhibition of MMP-1 suppression in UV-irradiated human dermal fibroblasts. The higher contents of ginsenoside Rg2(8.234%), Rh1(5.749%), F4(3.881%) in isopropyl alcohol fraction of ginseng flower buds obtained by ultrasonication process at 600W(100℃) for 16 hours. GFB-IF had collagen synthesis effect. GFB-IF induced a significant dose-dependent decrease in the expression for MMP-1 protein. These results suggest that GFB-IF is a potential candidate for the prevention and treatment of wrinkle improving.

  • Inonotus obliquus is a traditional medicine mushroom that was developed from traditional medicine originating in ancient. It has been applied for cancer or immunotherapy, but its effect on pulmonary tuberculosis is not reported. Therefore, we measured the pulmonary tuberculosis therapeutic effect of methyl alcohol extract from MGIT 960 system with fluorescent indicator. Inonotus obliquus extract showed 14 day more inhibitory activity than the positive control. In addition, the anti-pulmonary tuberculosis activity of Inonotus obliquus was $50{\mu}m$. These results suggest that Inonotus obliquus methyl alcohol extracts could contribute to inhibition of pulmonary tuberculosis.

  • To increase the skin permeation rate of flurbiprofen, fatty alcohols were added in propylene glycol vehicle containing 1% flurbiprofen. Their enhancing effect on the skin permeation of flurbiprofen was evaluated using Keshary-Chien diffusion cells fitted with excised rat skins. Lauryl alcohol and oleyl alcohol increased the skin permeation rate of flurbiprofen 11.3 and 8.5 fold, respectively, compared to the control vehicle.

  • The volatile flavor components in mash of nonglutinous rice Takju brewed with or without addition of the starter were determined by GC and GC-MS using polar column. Various kinds of volatile components including alcohols(10), esters(9), organic acids(2) and aldehydes(7) were found in mash of nonglutinous rice Takjus. At the beginning stage of fermentation, 3 to 7 volatile flavor components were detected. The number of volatile flavor components were increased to 26 of to 28 after 16 days fermentation. Early in the brewing, just 3 kinds of flavor components including ethyl acetate, ${\beta}-phenylethyl$ acetate and acetic acid were detected in mash of nonglutinous rice Takju without the addition of the starter, when starter is added additional compounds of alcohol including ethanol were detected, which is suggested to be the effect of flavors originated from the starter. The common flavor compounds through the entire process of fermentation in mash of nonglutinous rice Takju were ethyl acetate, ${\beta}-phenylethyl$ acetate and acetic acid. The relative amount(peak area %) of flavor components were changed with the fermentation period, but the major volatile flavor components were ethyl alcohol, iso-amyl alcohol, hexenyl alcohol, ethyl acetate, ${\beta}-phenylethyl$ acetate and ${\beta}-phenylethyl$ alcohol. The relative amount(peak area %) of ethyl alcohol was the highest in mash of nonglutinous rice Takju with addition of starter. When the starter was not added in the mash of nonglutinous rice Takju, any alcoholic components were not detected in the early stage of fermentation. But the percent of peak area hexenyl alcohol was the highest after 16 days fermentation. Especially few sorts of ester were detected in mash of nonglutious rice Takju without addition of starter by 3 days fermentation.

  • The present study was designed to examine the effect of tested preparation, WY-91 (consisting of ginseng extract, ganoderma extract and Royal jelly) on alcohol-induced unusual metabolism(such as blood glucose(BG), triBlyceride(TG), and blood urea nitrogen(BUN) level in blood) and nrperinlental liver injury($CCl_4$ and high fat diet) in mice. WY-91 lowered the level of blood glucose (BG),triglyceride(TG) and blood urea nitrogen(BUN) induced by alcohol in a dose-dependent manner. This preparation could protect hepatic function from a damages caused by high fat diet and $CCl_4$ administration(p.o.).

  • Poly(vinyl alcohol) (PVA), PVA/Montmorillonite (MMT), PVA/Silver (Ag), and PVA/MMT/Ag nanocomposite nanowebs were prepared by electrospinning technique in aqueous solution. In order to investigate the effect of inorganic materials on the morphology and thermal properties of PVA based nanocomposite nanowebs, experiments were performed with 5 wt.% of MMT and Ag. Field emission type scanning electron microscopy, transmission electron microscopy (TEM), reflection type X-ray diffraction (XRD), and thermal gravimetric analyzer were utilized to characterize nanocomposite nanowebs. TEM and XRD results show MMT and Ag were well dispersed in PVA nanowebs. Those inorganic nanoparticles enhanced thermal property of the nanocomposite nanowebs.
