The sanitizing effect of irradiation on the fresh vegetable extract juices was investigated. Total bacteria, coliform bacteria and total ascorbic acid were determined during the storage periods at 4oC. Chlorophyll, carotenoid, tannin, electron donating ability and peroxidase activity were determined immediately after irradiation. Results showed that the viable cells were detected below the level of 105 CFU/ml during 12 days with doses of 3 and 5 kGy. Total ascorbic acid and tannin contents increased immediately after irradiation. However, irradiation didn't affect chlorophyll and car otenoid contents, electron donating ability, and peroxidase activity. It was considered that irradiation was effective in sanitizing fresh vegetable extract juices.

In this study, ten different bio-adsorbents were prepared by immobilization of vegetable tannins such as mimosa(Catechol Tannin) and chestnut(Pyrogallol Tannin) on the collagen matrix which was derived from during leather manufacturing processing. Removal efficiency of Cu(II), Cd(II), Zn(II), Pb(II), Cr(III) by each bio-adsorbent in synthetic wastewater was evaluated by a laboratory-scale batch reactor at different reaction conditions. When mimosa was used as a vegetable tannin, the penetration efficiency of mimosa into the inner bundle of fiber depended on the dose of the naphthalene condensated penetrant; 3% ${\geq}$ 1.5% > 0%. For all bio-adsorbents, removal of heavy metal ions was not observed below pH 3.0 but was rapidly increased between pH 3.0 and 6.0, showing near complete removal of all heavy metal ions except Zn(II) above pH 6.0. Removal of Cr(III) was quite similar for all bio-adsorbents while removal of Cu(II), Zn(II) and Pb(II) was higher by bio-adsorbents immobilized with chestnut than that by mimosa. Adsorption of Pb(II) and Cu(II) by S10 bio-adsorbent was little affected by the presence of monovalent and divalent electrolytes as well as variation of 1000 times ionic concentration with $NaNO_3$.

From the ancient Korea to the late Joseon Korean fur and leather had been preferred in and out of Korea for their good quality and excellent manufacturing skill. Since Unified Silla (A.D.676${\sim}$A.D.936) Korean fur and leather were manufactured divisionally by workmen specialized in materials and products, and such manufacturing process was succeeded to Goryeo and Joseon. Manufacturing of fur and leather was consisted of as follows: hunting and butchering - peeling - beating with a paddle and removing fat - oil manufacturing - drying - tanning, then cutting and sewing, and there was a special caring method. In order to make good fur and leather, each process of manufacturing needed particular techniques and all available methods were tried to have tender fur and leather by using smoking, excrement, lime, vegetable tannin and even cerebral liquid. And also required mouth-chewing and hand-pounding with a lot of time and of labor Keeping furs resilience and flexibility, sowing several skins together, even when the after-all-process skin was converted into clothes, was much more difficult than sewing fabric. Thus, the manufacturing cost was as much expensive as skin materials, and the volume of manufacturing of fur and leather was also limited. Therefore, fur and leather must have been popular for scarcity value in the manufacturing process, and this scarcity must have caused an extreme luxury of fur.

Four bacteria producing viscous exopolysaccharides (EPSs) were isolated from Korean fermented vegetables (Cucumber kimchi, Young radish kimchi, Green onion kimchi) using a selection medium intended for isolating bacteria with tannin-degrading activity. They were identified phylogenetically by 16S rDNA sequence analysis and found to be very close to Enterobacter cowan ii, Escherichia senegalensis, Enterobacter asburiae, and Enterobacter ludwigii. Strain CK31, the most efficient EPS-producer, produced a heteropolysaccharide with an approximate molecular weight of 420 kDa. The neutral sugar fraction of the EPS was composed of rhamnose, fucose, arabinose, mannose, galactose, and glucose.

A new peanut variety "Seonan" (Arachis hypogaea ssp. hypogaea L.) was developed at the Yeongnam Agricultural Research Institute, NICS, in Milyang in 2007. It was developed from the cross between the erect short stem cultivar "SP9128" and the high-yielding cultivar "Daekwang". "Seanan" which is Virginia plant type has 18 branch number per plant with early maturing and long-ellipse shaped large kernel. Each pod has two grains with brown testa and 100 seed weight was 87 g in the regional yield trials (RYT). Especially this variety has resistance to lodging owing to short stem. The free sugar and tannin content of fresh peanut are 3.7% and 0.48%, respectively, similar to check variety. In the regional yield trials "Seonan" was outyielded than check variety by 14% with 8.59 MT/ha for fresh pod and by 7% with 3.75 MT/ha for grain.
