A matallo-organic solution was stamped from the channels of a polymer stamp onto a glass. The precursor solution consisted of copper 2-ethylhexanonate, 2-ethoxyethanol as a solvent and ethylene glycol to improve surface energies. The solution was deposited to the polymer stamp by spin coater. After drying the solution in channels of the stamp, the dried ink was transferred to a substrate by debonding from channels. The process parameters such as solution compositions and pressing methods were discussed experimentally to form a copper pattern whose morphology was excellent.

Pediococcus pentosaceus SA131 was isolated from jeotgal, is the bacteriocin producer against bovine mastitis pathogens, Streptococcus uberis E290, Enterococcus gallinarum E362, and Staphylococcus epidermidis ATCC 12228. The medium composition for pediocin SA131 production by P. pentosaceus SA131 was optimized using response surface methodology. Component of medium was studied as carbon source (glucose, fructose, lactose, glycerol, sucrose, maltose, and mannitol), nitrogen source (beef extract, yeast extract, peptone, malt extract, and tryptone), mineral and surfactant (MgSO4, KH2PO4, (NH4)2SO4, MnSO4, NaCl, sodium acetate, and Tween 80). Through one factor-at-a-time experiment, glucose, fructose, yeast extract, malt extract, NaCl, MgSO4, and Tween 80 were determined as the good ingredient. The effects of major factors for pediocin SA131 production were investigated by two-level fractional factorial designs (FFD). By a 2(4) FFD, fructose, yeast extract, and MnSO4 were found to be the important factors for the bacteriocin production. Subsequently, a 2(3) central composite design (CCD) was adopted to derive a statistical model for optimizing the composition of the fermentation medium. The estimated optimum composition for the production of pediocin SA131 by P. pentosaceus SA131 was as follows; 0.13% fructose, 1% glucose, 1.8% yeast extract, 2.58% MnSO4, 0.2% NaCl, and 0.2% Tween 80. The pediocin production under optimized medium was increased to 1,000 AU/mL, compared to the 400 AU/mL in MRS medium.

Menkes' syndrome is a neurodegenerative disease of copper metabolism, which is inherited by X-linked pattern. The clinical manifestations and laboratory deficits are mostly explicable in term of failure of the numerous copper-dependent enzyme systems. The incidence is presumably in the range 1 in 50,000 to 1 in 1,000,000. Survival varies between 3 months and 3 years, but is most often about 12 months. We experienced one case of Menkes' syndrome in 2 months old male who had frequent seizure, abnormal hair, hypopigmentation and low serum copper level. A review of literatures was also presented briefly.

Component of medium was studied as carbon source (glucose, fructose, lactose, glycerol, sucrose, maltose, and mannitol), nitrogen source (beef extract, yeast extract, peptone, malt extract, and tryptone), mineral and surfactant ($MgSO_4$, $KH_2PO_4$, $(NH_4)_2SO_4$, $MnSO_4$, NaCl, sodium acetate, and Tween 80). Through one factor-at-a-time experiment, glucose, fructose, yeast extract, malt extract, NaCl, $MgSO_4$, and Tween 80 were determined as the good ingredient. The effects of major factors for pediocin SA131 production were investigated by two-level fractional factorial designs (FFD). By a $2^4$ FFD, fructose, yeast extract, and $MnSO_4$ were found to be the important factors for the bacteriocin production. Subsequently, a $2^3$ central composite design (CCD) was adopted to derive a statistical model for optimizing the composition of the fermentation medium.

We developed a method for fabricating poly(ethylene glycol) (PEG) nanostructures using capillary lithography mediated UV exposure. A PEG dimethacrylate (PEG-DMA) was used for crosslinking, which could be applied to other PEG polymers having a crosslinking group. In comparison to unstructured, planar PEG films, the hydrophobicity was significantly enhanced on PEG nanostructures presumably due to embedded air in the nanostructures, as confirmed by contact angle measurements of water. A number of proteins and cells were tested to examine the effects of the modification of surface properties on protein adsorption and cell adhesion. It was found that proteins and cells adhered on a nanostructured PEG surface slightly higher than on a bare PEG film, but much less than on glass control, which could be attributed to the increased surface area and hydrophobicity.

<P>Visual inpainting is an interpolation problem that restores an image or a frame with missing or damaged parts. Over the past decades, a number of computable models of visual inpainting have been developed, but most of these models are based on the pixel domain. Little theoretical and computational work of visual inpainting is based on the compressed domain. In this paper, a visual inpainting model in the discrete cosine transform (DCT) domain is proposed. DCT coefficients of the non-inpainting blocks are utilized to get block features, and those block features are propagated to the inpainting region iteratively. The experimental results with I frames of MPEG4 are presented to demonstrate the efficiency and accuracy of the proposed algorithm.</P>
