Abstract: The present invention provides a lactase-containing double microcapsule which includes; lactase provided as a core material; and a primary coating material and a secondary coating material, which are sequentially coated on the core material to be formulated, a method for preparing the lactase-containing double microcapsule, and a dairy product including the lactase-containing double microcapsule as a use of the lactase-containing double microcapsule.

Abstract: Electrodes in a plasma display panel are manufactured by (A) forming a pattern for electrodes on a substrate to be wider than a desired pattern, (B) coating photoresist on the electrode pattern, (C) disposing a photomask having the desired pattern on the photoresist and exposing the photoresist, and (D) forming electrodes having the desired pattern by developing and baking the exposed electrode pattern by using the photomask. Thus, the cost for a material for electrodes can be reduced, and short circuiting between the electrodes and the edge curl phenomenon can be prevented.

Abstract: A precursor composition for a metal oxide, and a preparation method therefor. The precursor composition contains metal alkoxide and aromatic hydrocarbon. The precursor composition for a metal oxide exhibits excellent stability to heat and moisture in air, and is easily mixed with various organic solvents and binders, and easily formulated in paste form. Also, various metals are evenly mixed in the paste, so the precursor composition is very useful in forming a composite metal oxide film. In the case where the composite metal oxide film is used as a protective film for a plasma display device, the composite metal oxide film can easily generate secondary electrons even at a low discharging voltage. Thus, the driving voltage of the plasma display device can be lowered. In addition, the precursor composition for a metal oxide can be used as an inorganic binder or for preparing a catalyst.
