Abstract: Disclosed is a method of manufacturing a polyurethane filter foam having excellent air permeability, elasticity, and restoring force. In the method of manufacturing the polyurethane filter foam, the cell size of the filter foam is made regular by controlling the pressure by adjusting the diameter of the foaming head of a foaming machine, rather than adding a cell opener, cell irregularity caused by poor dispersion of the cell opener is alleviated, and air permeability, porosity, and compression set are excellent.

Abstract: Disclosed are various methods for transmitting or receiving data or control information having high reliability conditions. A method for operating a terminal which transmits uplink control information (UCI) includes: a step of generating UCI; a step of comparing the priority of an uplink (UL) control channel for the transmission of the UCI with the priority of a UL data channel when some symbols of the UL control channel and the UL data channel overlap; and a step of selecting the UL channel having a higher priority among the UL control channel and the UL data channel, and transmitting the UCI to a base station through the selected UL channel.

Abstract: A display apparatus for searching and a control method thereof are provided. The method includes displaying an image content, determining whether a search function is performed while the image content is displayed, and in response to the determining that the search function is performed while the image content is displayed, transmitting information of the image content to an external server. The method further includes receiving, from the external server, information of a search record of one or more viewers of the image content, and providing information of one or more search terms that are related to the image content, based on the information of the search record.

Abstract: An apparatus and a method transact digital contents. More particularly, an apparatus and a method for inserting a purchaser's signature into digital contents and providing the same in a digital contents management system are provided. The apparatus includes a purchaser terminal, a contents server, and a receiver terminal. The purchaser terminal detects a user's input, writes a signature to be inserted into contents, and transmits the written signature to a contents server when purchasing contents. The contents server inserts the signature received from the purchaser terminal into original digital contents. The receiver terminal receives and reproduces the original digital contents to which the signature has been added.
