Abstract: An audio signal processing method, which is executed by a processor electronically communicating with a deep neural network within a computing system, may comprise: acquiring, by the processor, an input signal before encoding and an output signal after quantization and decoding; calculating, by the processor, a perceptual global loss for a frame corresponding to the input and the output signals; acquiring, by the processor, a plurality of subframes corresponding to the input and output signals by applying a windowing function to the frame of the input and output signals; calculating, by the processor, perceptual local losses for the plurality of subframes corresponding to the input and output signals; and acquiring, by the processor, multi-time scale perceptual loss based on the perceptual global and local losses.

Abstract: The present disclosure relates to a method of preparing an organic zinc catalyst through solid phase blending that does not require a solvent and a washing process, and a method of preparing a polyalkylene carbonate resin by using the organic zinc catalyst prepared thereby.

Abstract: The present invention provides an organic compound represented by: an organic light emitting diode and an organic light emitting display device using the organic compound. The organic compound of the present invention is capable of reducing a driving voltage of an organic light emitting diode and improving an emitting efficiency and a lifetime of the organic light emitting diode and the organic light emitting display device including the organic compound.

Abstract: A method and apparatus for adjusting a screen. The apparatus for adjusting a screen includes an on screen display (OSD) adjusting unit and a screen dividing unit. The OSD adjusting unit is overlaid on a reproduced image for providing an interface to allow screen adjustment by a user. The screen dividing unit displays an area of the screen based on the adjusted screen state using the OSD adjusting unit, while keeping the other area of the screen intact.
