Abstract: A method for encoding that adaptive intra prediction based on a mode of variable size partition is applied in a macro block, includes calculating average values of the macro blocks to set the representative values of the macro blocks; and generating minor macro blocks by partitioning the macro blocks based on partition of the exceeded portion and calculating average values of each of the minor macro blocks and then, setting representative values of each of the minor macro blocks using the calculated average values. Further, the method includes generating minor macro blocks by partitioning the macro blocks based on partition of horizontal and vertical directions, calculating average values of each of the minor macro blocks and then, setting representative values of each of the minor macro blocks using the calculated average values.

Abstract: Disclosed is a method for manufacturing a nano wire grid polarizer, including: applying a curable resin on a glass substrate, and then forming a nano pattern by pressurizing the curable resin with a nano imprint mold; processing a surface of the nano pattern in which an upper part of the nano pattern is hydrophobicized and an inside of the nano pattern is hydrophilicized; filling the inside of the nano pattern with nano metal particles; and forming a nano wire grid polarizer by removing the nano pattern.

Abstract: A method of manufacturing a transparent film for reducing electromagnetic waves includes forming a first dielectric layer and forming a pattern layer on the first dielectric layer. The pattern layer is made of a transparent electrode material having surface resistance.

Abstract: A technology enabling a base station to transmit acknowledgement (ACK)/negative ACK (NACK) information about data received from a terminal is provided. A cyclic shift value difference of each terminal may be maximized and a radio resource for transmitting the ACK/NACK information may be assigned without collision.
