Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.

Abstract: Provided is a geothermal heat system having reduced heat source residual heat of a geothermal heat pump. The geothermal heat system includes a ground heat exchanger unit, a geothermal heat pump, and a residual heat storage tank. A portion of heat source residual heat remaining in the geothermal heat pump is transferred on a geothermal heat exchange medium passing through the geothermal heat pump so as to be stored in the residual heat storage tank. As the internal temperature of the residual heat storage tank gradually becomes the same as the temperature of the underground, the thermal load of the underground is removed. At least a portion of the heat source residual heat produced during provision of cooling/heating to the location of use is processed, thereby improving the operating efficiency of the geothermal heat system having reduced heat source residual heat of a geothermal heat pump.

Abstract: The present invention relates to a composition comprising adiponectin-derived peptide fragments and, more specifically, to a cosmetic composition and pharmaceutical composition for promoting hair growth comprising, as an active ingredient, one or more adiponectin-derived peptides selected from the group consisting of amino acid sequences of SEQ ID NOS: 1 to 21. The adiponectin-derived peptides activate the cell division of dermal papilla cells and outer root sheath cells of hair follicles, promote hair growth in the hair follicles, and also increase the expression of hair growth factors in the dermal papilla cells, and thus a composition of the present invention comprising the adiponectin-derived peptides can be effectively used to promote hair growth and inhibit hair loss.
