Abstract: A method of a first user equipment (UE) may comprise: receiving a downlink (DL) reference signal transmitted by a base station using a beam included in a beam candidate group to be used for sidelink (SL) communication with a second UE; measuring a DL reference signal received power (RSRP) of the DL reference signal; determining a transmit power of a beam included in the beam candidate group based on the measured DL RSRP; and transmitting SL data to the second UE with the determined transmit power.

Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

Abstract: Provided is an unconstrained vibration damping metal sheet with foam pores. The unconstrained vibration damping metal sheet of the present invention comprises: a metal sheet; an organic-inorganic pretreatment layer containing an acrylic resin formed on the metal sheet; and a foam resin layer formed on the pretreatment layer, the foam resin layer containing, based on weight % thereof, a thermoplastic polyvinyl chloride resin: 40-80%, a plasticizer: 5-40%, a foaming agent: 0.1-10%, an oxide-based crosslinker: 1-4%, and spherical silica: 1-10%.

Abstract: A transportation system of a cassette comprises a port and a system controller. The port accommodates a cassette carrying a glass substrate, and the port includes displacement sensors for sensing a position of a cassette. The system controller calculates a distortion amount of the cassette using sensed values of the cassette and determines if the cassette is in a normal settlement status by comparing the distortion amount with a tolerance value. Therefore, the position of the cassette can be automatically taught without clamping operation of a clamping device clamping the cassette disposed in the port, thereby preventing defects of the glass substrate by removing various defect-causing factors such as particles and static electricity that may occur during a conventional clamping operation. In particular, quality defects of OLED can be eliminated by preventing particles and static electricity that affect product quality defects in the OLED manufacturing process.
