The present invention relates to a method for producing a transgenic pig in which immune rejection response is inhibited, and in which human HO-1 genes and TNFR1-Fc fusion genes are simultaneously expressed. The present invention also relates to a transgenic pig for organ transplantation, which is produced by the method, and in which immune rejection response is inhibited. The present invention also relates to a somatic-cell-donating cell strain for producing the transgenic pig, and to a method for producing organs, from the transgenic pig, in which the immune rejection response is inhibited.

The present invention relates to an artificial wood production method in which a simple arrangement is employed to allow efficient continuous extrusion of artificial wood which is formed from a composite material comprising an outer layer and an inner layer and in which filaments are disposed continuously in the length direction in the inner layer. The present invention also relates to an artificial wood produced by this artificial wood production method. In the artificial wood production method according to the present invention, artificial wood is produced which comprises: an outer layer formed by mixing a wood fraction with an artificial resin; an inner layer formed integrally with the outer layer by means of co-extrusion; and a filament tow disposed continuously in the length direction in the inner layer. A characterising feature of the present invention is that the filament tow is disposed continuously in the length direction in the inner layer by being introduced, into the mould for forming the inner layer, through a filament-introduction pipe obtained by the integral formation of an inclined part, which is disposed at an incline from the outside of the mould towards the front inside the mould, and introduction guide parts, which are disposed in parallel inside the mould.

Disclosed are native rock combined with resin having multi-color vein by combining natural inorganic mineral with resin, thus obtaining a compound having a multi-color tone, which is then subjected to spraying of various pigments having different colors, and a manufacturing method thereof. The manufacturing method includes combining 88-89 wt% of a plurality of types of natural mineral powder with 11-12 wt% of resin, thus preparing a compound 13 having a multi-color tone and including bulk particles; feeding the compound having a multi-color tone in a sheet form on a stacking plate 14 without additional grinding, thus forming a compound sheet 15; spraying a plurality of pigments having different colors on the compound sheet, and then stirring the compound sheet throughout the entire thickness thereof, thereby forming the compound sheet having multi-color vein; and subjecting the compound sheet to compression molding under high pressure, thereby manufacturing native rock combined with resin having a predetermined strength.

A quasi-monochromatic x-ray optical filter according to the present invention is a device for filtering a polychromatic x-ray to obtain a quasi-monochromatic x-ray having a specific energy band. The quasi-monochromatic x-ray optical filter includes a plurality of reflecting mirrors on which respective multi-layer films for selectively reflecting x-rays based on Bragg's law are deposited, a reflecting mirror chamber for fastening the reflecting mirrors in a specific geometrical arrangement, and an alignment mechanism for aligning the chamber in a commercial x-ray generation device. Since a quasi-monochromatic x-ray multi-energy imaging system using the optical filter can clearly distinguish the spectrum regions of multi-energy from each other using a quasi-monochromatic x-ray having multi-energy, clear images can be acquired even after a small exposure in the case where adjustment is performed to use an optimal energy value.

Disclosed herein is a method of producing a coating agent for antireflection coating, comprising: mixing and stirring an organic solvent, a surfactant, and colloidal silica having a particle size of 2 ~ 50 nm and a concentration of 5 ~ 40% to form a solution including silica reverse micelles having a particle size of 10 ~ 100 nm; mixing and stirring a silane derivative in the solution including silica reverse micelles to surface-treat the silica reverse micelles; and removing the organic solvent and surfactant from the solution including silica reverse micelles to produce porous silica particles having a particle size of 10 ~ 100 nm. The antireflection film produced using the method has high transmissivity, low turbidity, and excellent antireflection.
