Abstract:
PURPOSE: An organism adhesive composition and a manufacturing method thereof are provided to remarkably reduce the side effect such as inflammation by hindering the penetration of adhesive ingredient into the injury. CONSTITUTION: An organism adhesive composition comprises highly polymerized compound and cyano acrylate which indicated as below chemical formula 1. In the formula, R1 is H or COOH, R2 is H or C1-4 alkyl, and n is an integer from 10 to 1000. The R2 is H or methyl. The cyano acrylate is selected from the group which is consisted of methyl 2- cyano acrylate, ethyl 2-cyanoacrylate, butyl 2- cyano acrylate, iso-hexyl 2- cyano acrylate, 2- cyano acrylate, octyl 2- cyano acrylate, ethoxyethyl 2- cyano acrylate, isobutyl 2- cyano acrylate, and hexyl 2-cyano acrylate.
Abstract:
PURPOSE: A diffraction grid base X-ray device is provided to increase spatially coherent X-ray beams and to transmit inphase X-rays by an interference effect and the diffraction of X-rays, thereby obtaining images with high resolution and a low amount of the X-rays. CONSTITUTION: A diffraction grid base X-ray device comprises an X-ray source(100), diffraction grids, and an X-ray detector(10). The X-ray source comprises one or more insulating columns and radiates X-rays in a vacuum condition. The diffraction grids generate coherent X-rays by receiving the radiated X-rays and transmits the X-rays penetrated through an inspection object arranged in an inner side by forming a phase difference. The X-ray detector receives the transmitted X-rays and converts the same into electrical signals, thereby transmitting as digital image information.
Abstract:
PURPOSE: A multiple array X-ray system is provided to successively or simultaneously take a photograph of a patient or an object by using a plurality of unit X-ray sources. CONSTITUTION: An X-ray director(10) visualizes a discharged X-ray. A main vibration chamber(20) is separated from the X-ray director. A unit X-ray source(100) discharges electrons in a vacuum to generate the X-ray. The unit X-ray source is attached to one side of the main vacuum chamber at regular distance.

Abstract:
PURPOSE: A three dimensional image compensation method is provided to effectively offer orthodontic treatment by accurately analyzing the location change of teeth. CONSTITUTION: A compensation target image(200) and a reference image(100) are located at three reference points. A line which connects two points among the tree reference points in the compensation target image is established. A line which connects two points among the tree reference points in the reference image(101-103) is established. The compensation target image is rotated in order to match the line of the compensation target image with the line of the reference image.
