Abstract: The present invention relates to an anti-inflammatory, skin-regenerative, whitening, antioxidant, or wound-healing composition containing a culture medium of adipose-derived stem cell-T (ADSC-T) cells as an active ingredient, in which T-antigen is introduced into an adipose-derived stem cell. The culture medium of ADSC-T cells, according to the present invention, has remarkable effects for treating or inhibiting inflammation by alleviating atopic dermatitis, which is an autoimmune disease, and inhibiting NF-?B activities through an increase of an I?b? expression. Additionally, the culture medium, according to the present invention, exhibits: excellent skin regenerative effects by having effects of enhancing skin collagen elasticity and reducing wounds, in a collagen culture; excellent skin whitening effects by inhibiting tyrosinase activities and melanin production; and excellent anti-oxidation effects by inhibiting DPPH radical activities.

Abstract: Dielectric ceramic compositions for microwave application which are expressed as (1-x)ZnNb2O6- xTiO2 and designed with mole fractions of TiO2 (x=0.2 to 0.8). CuO of 0.5 to 12.0 % by weight of the total weight of the compositions is added to the compositions. At least one additive oxide of 0.05 to 5.0% by weight of the total weight among V2O5, Sb2O5, Bi2O3, B2O3, NiO, WO3, AgNO3, ZnO, and MgO is added to the compositions. They have good sintering and dielectric characteristics and made through simple manufacturing processes, and lower the production costs.
