Abstract: The present invention relates to a composition comprising a Moutan root bark extract as an active ingredient, and particularly to a composition for the prevention and treatment of athlete's foot, osmidrosis, or acne; a composition for oral cleansing; a bactericidal/disinfectant composition; a composition for eliminating dandruff-causing pathogens and controlling odor, and a functional kitchen detergent composition. The compositions comprising the Moutan root bark extract as an active ingredient of the present invention have superior bactericidal effects against bacteria including athlete's foot-causing pathogens, skin eczema-causing pathogens and skin flora, and fungi, and they can be easily and simply applied to medicines, cosmetics, or cleansing agents.

Abstract: A virtual reality embodying system uses 2D images and HDRI data taken of a target object through a camera to embody virtual reality. A modeling unit compares the 2D image's coordinate with a real coordinate to calculate a transform matrix, calculates a vanishing point of a reference vector, uses the vanishing point to calculate a camera matrix, uses the camera matrix and the transform matrix to calculate a rotation matrix and a translation matrix, and uses the rotation matrix and the translation matrix to model the 2D image into a virtual model. A rendering unit uses the HDRI data as texture to render the virtual model, and embodies the HDRI into an extended VRML node to apply the virtual model to the VRML environment.

Abstract: The method of the present invention includes the first step of applying power to a character and/or image display apparatus and setting up input/output port values and initialization values, the second step of initializing all LED values and clearing a screen, the third step of reading initial picture data from a nonvolatile backup memory, the fourth step of writing the data read from the backup memory into a working memory, the fifth step of reading initialization data from the working memory, the sixth step of displaying an initial picture and performing a still mode until a rotation speed of a motor becomes stable, the seventh step of reading data other than the initialization data from the working memory, the eighth step of sequentially performing modes corresponding to commands contained in the read data, and the ninth step of repeating the above seventh and eighth steps until all commands stored in the working memory are processed.
