Abstract: A polymer capable of securing pattern uniformity in a photoresist pattern, the polymer containing a photoacid generator by including a structure unit represented by Chemical Formula 1a; and a structure unit represented by Chemical Formula 1b as shown in the specification.

Abstract: A clothes treating apparatus including a housing; a tub inside the housing; a drum configured to be rotated inside the tub; a spin-drying shaft connected to the drum; a motor assembly including a rotor configured to be rotated; a coupler: a first element; and a second element inside the coupler, wherein the coupler is positionable in a first position in which the coupler is coupled to the spin-drying shaft and the rotor, the coupler is positionable in a second position in which the coupler is coupled to the spin-drying shaft and disengaged from the rotor, and with the coupler being positioned in the second position, the first element and the second element are configured to interact to move the second element away from the first element and thereby move the coupler from the second position to the first position.

Abstract: The present disclosure relates to an image processing device including: a memory configured to store one or more instructions; and a processor configured to execute the one or more instructions stored in the memory to: extract one or more input patches based on an input image; extract one or more pieces of feature information respectively corresponding to the one or more input patches, based on a dictionary including mapping information indicating mappings between a plurality of patches and pieces of feature information respectively corresponding to the plurality of patches; and obtain a final image by performing a convolution operation between the extracted one or more pieces of feature information and a filter kernel.

Abstract: Provided is a display apparatus including: a liquid crystal panel; a source driver configured to output a grayscale voltage to the liquid crystal panel; a timing controller configured to transmit a source control signal to the source driver; a scaler configured to transmit image data corresponding to content received from an external source to the timing controller; and a controller configured to adjust a driving scan rate of the liquid crystal panel to correspond to a set scan rate of the content, and control at least one of the scaler or the timing controller to adjust a data rate of an output signal based on the driving scan rate.

Abstract: A washing machine includes a tub, a drum, a pulsator, a motor assembly, including a rotor, to supply a driving force, a reduction gear module couplable to the rotor of the motor assembly so that a portion of the reduction gear module is rotatable at an angular velocity less than an angular velocity at which the rotor is rotated, a washing shaft couplable to the pulsator and the portion of the reduction gear module so that the pulsator is rotatable at an angular velocity less than the angular velocity at which the rotor is rotated, a spin-drying shaft couplable to the drum, and a coupler configured to be couplable to the spin-drying shaft and the rotor so that the spin-drying shaft is rotatable at the angular velocity at which the rotor is rotated, where the coupler includes a coupler body having a receiving space to receive the reduction gear module.

Abstract: A mobile terminal includes a main body; a front camera disposed at a front side of the main body; a display disposed at the front side of the main body; and a controller configured to control the display such that the display displays a preview image within a first portion of the display, wherein the preview image is obtained via the front camera; displays the preview image within a second portion of the display in response to an input, wherein the first portion includes the second portion and further includes a remaining portion; and displays a second image within the remaining portion of the first portion in response to the input.
