Abstract: The present invention relates to a method for preparing a polyamide resin, comprising the steps of: (a) preparing a polyamide polymer by anionically polymerizing a monomer including 2-pyrrolidone; (b) refining an unreacted monomer and a catalyst in the polyamide polymer with water; (c) pH-controlling through an ion exchange of the refined water; and (d) recovering the unreacted monomer by concentrating the pH-controlled water.

Abstract: The present invention relates to a microorganism producing inosine, which is one of purine nucleoside, an important material for 5?-inosinic acid synthesis, and method for producing inosine using the same. More particularly, the present invention relates to a recombinant microorganism of Corynebacterium genus producing inosine at high concentration by inactivating the gene encoding nucleoside hydrolase II and by enhancing the expression of the gene encoding 5?-nucleotidase, which still retains the characteristics of Corynebacterium ammoniagenes CJIP2401 (KCCM-10610).

Abstract: A color lighting apparatus and method which has a small optical apparatus or method illuminating color beams with a high optical efficiency and an image projection apparatus and method using the same. The color lighting apparatus includes a light source, a color beam separating unit for separating incident light according to predetermined wavelength bands, a first condensing lens which condenses the light separated by the color beam separating unit, and a scrolling unit which changes the travel paths of beams separated according to the predetermined wavelength bands, forms color bars at different locations, and scrolls the incident light so as to periodically scroll the color bars.

Abstract: An apparatus and method for automatically tracking an object is provided. The apparatus for performing the method includes a camera having a zoom lens, an automatic focus lens, and a charge coupled device for converting an image of an object input via the lens into electrical signals. The camera is mounted on a camera supporter to rotate the camera around a first axis and the axis perpendicular to the first axis. The supporter includes holes and sensors for detecting the rotational limit of the camera in the horizontal and vertical directions. A pan/tilt controller detects a motion vector of the object, and controls the camera to move in the direction and degree corresponding to the detected motion vector. A zoom focus controller performs a zooming operation to expand an object search region of the camera whenever the camera reaches the limit of the rotational range in at least one direction, and adjusts an automatic focusing lens.

Abstract: An apparatus and method for retrieving image information in a computer. A controller receives a schematic image inputted by a user and normalizes the input image to an image of a constant size. A feature vector of each sub block of the normalized image is extracted, and the extracted feature vector is quantized to one of representative values of a determined number within feature vector space. An image profile indicating the frequency of occurrence of the feature vector of the input image is generated with respect to a quantizing level. A profile of the input image is compared with a profile of each image in an image data base part. An image corresponding to a profile whose similarity is within a reference value is displayed.

Abstract: A video conference system includes terminals where each terminal extracts only an object image from a picture that includes an object and a background. The extracted object image signal is transmitted to a controller to be synthesized on a background image, and a synthesized image is simultaneously transmitted to a plurality of terminals. Each of the plurality of terminals encodes only an object image signal corresponding to a conference participant out of a photographed video signal to output an encoded object signal. Each terminal receives and decodes a compression-encoded image signal to display a compressed image. A multi-point controller receives and decodes the encoded object signals from the plurality of terminals to restore object images, adjusts the size of the object images, synthesizes a background image with the size-adjusted object images, and compression-encodes the synthesized image to output the compression-encoded image signal to the plurality of terminals.
