A method for performing transposition of second-generation superconducting wires, and a superconducting coil manufactured using the same are disclosed. The method for manufacturing a second-generation superconducting wire comprises: slitting a multiple-layered thin superconducting wire film, obtained by epitaxial growth, to form a zigzag-shaped slit portion which includes a plurality of sections each having a predetermined first length and a bent portion having a predetermined second length; continuously and repeatedly processing each section of the slit portion of the superconducting wire film until a desired length is processed to obtain first and second wires using two superconducting wire films; positioning the first and second wires so their bent portions face each other; and interweaving the first and second wires together so the first wire passes over the second wire at their first overlapped portion and below the second wire at their second overlapped portion, to couple the first and second wires.

Disclosed herein is a method of manufacturing a continuous disk winding for high-voltage superconducting transformers that has special features of no joint and low loss, which are advantages of a layer winding, while being formed in the shape of a disk winding, which is advantageous in voltage distribution and insulation. The method includes lapping a high-temperature superconducting wire using Kapton films to apply multiple layers of insulation around the high-temperature superconducting wire, fixing one end of the high-temperature superconducting wire to a current inlet terminal of a bobbin, to the lower end of which is attached a fixing plate, which has the current inlet terminal, and winding the high-temperature superconducting wire on the bobbin by the predetermined number of turns, fitting a disk having a slit formed therein onto the bobbin to form high-temperature superconducting wire layers, inserting the high-temperature superconducting wire into a front end of the slit of the fitted disk and moving high-temperature superconducting wire to a rear end of the slit such that the high-temperature superconducting wire can be wound on the next layer by the predetermined number of turns, fitting a plurality of disks, each of which has a slit formed therein, onto the bobbin at predetermined intervals to form a plurality of high-temperature superconducting wire layers, and repeatedly winding the high-temperature superconducting wire for each disk such that the high-temperature superconducting wire is wound from one end of the bobbin to the other end of the bobbin, and, after the winding operation is completed, fixing the other end of the high-temperature superconducting wire to a current inlet terminal of another fixing plate attached to the upper end of the bobbin.

A mirror package is provided which can reflect a laser to an external screen according to a video signal when the laser enters from outside, and a method of manufacturing the mirror package. The mirror is packaged with a glass to protect from external contamination, an inlet and an outlet are formed by, for example, an anisotropic etching on the glass and blocks a reflected light reflected from the glass. The mirror package is formed as a set, combined on a wafer using a wafer level package and diced to individual chips. Subsequently, a productivity is improved and a ghost image or phenomenon is removed.

A method and apparatus for generating discriminant functions for distinguishing obscene videos by using visual features of video data, and a method and apparatus for determining whether videos are obscene by using the generated discriminant functions, are provided. The method of generating discriminant functions includes: creating a first frame set by extracting a predetermined number of frames for each video data unit from a group of video data classified as obscene or non-obscene, and creating a second frame set by selecting the frames; generating a frame based discriminant function by extracting visual features of frames of the second frame set, and then generating a first discriminant value by determining whether each frame of the first frame set contains obscene video data; generating a group frame based discriminant function by extracting visual features of a group of frames of the first frame set, and then generating a second discriminant value by determining whether the frames of the group contain obscene video data; and generating a synthetic discriminant function by using the first and second discriminant values as a representative value of the video data. Accordingly, obscene video data stored in a computer system can be automatically and accurately distinguished.

An image preprocessing function for improving a hot code recognition rate. To implement this function, when a hot code pattern is input, by making a dark portion darker and a bright portion brighter so that an edge portion between black and white is more clearly identified, a difference between the hot code pattern and its background is clarified. Accordingly, an improved hot code recognition rate can be obtained.
