Abstract: Disclosed herein are a decoding method and apparatus and an encoding method and apparatus for deriving an intra-prediction mode. An intra-prediction mode may be derived using a method for deriving an intra-prediction mode based on a neighbor block of the target block, a method for deriving an intra-prediction mode using signaling of the intra-prediction mode of the target block, or a method for deriving an adaptive intra-prediction mode based on the type of a target slice. An MPM list may be used to derive the intra-prediction mode, and a temporal neighbor block or the like may be used to configure the MPM list.

Abstract: Disclosed herein are a decoding method and apparatus and an encoding method and apparatus that perform inter-prediction using a motion vector predictor. For a candidate block in a col picture, a scaled motion vector is generated based on a motion vector of the candidate block. When the scaled motion vector indicates a target block, a motion vector predictor of the target block is generated based on the motion vector of the candidate block. The motion vector predictor is used to derive the motion vector of the target block in a specific inter-prediction mode such as a merge mode and an AMVP mode.

Abstract: A ventilation sole for shoes is disclosed. The ventilation sole of the present invention has a vent hole (110), which is formed in a sidewall of the sole, an air supply hole, which is formed in the upper surface of the sole (100), and an air passage, which communicates the air supply hole with the vent hole, such that outside air is supplied into the shoe. Furthermore, the present invention is characterized in that a vent hole control device (200), which is opened or closed by a knocking operation, is installed in the vent hole (110) such that part thereof protrudes outside the sole (100), thus making it possible for a user to selectively open or close the vent hole (110), as necessary.
