Abstract:
PURPOSE: An operation method of a terminal and the terminal for performing a communication with a signal transmitter in consideration of the capacity of a battery in wireless network is provided to extend the lifetime of a cooperation group by selecting the terminal based on a channel gain between the terminal and a target terminal. CONSTITUTION: A channel gain measurer(211) measures a channel gain between a target terminal and a terminal(210). A transmission power decision unit(212) determines transmission power satisfying the demand data rate of the target terminal. A report unit(213) generates a report message by using the remaining battery capacity and transmission power of the terminal. The report message is transmitted to a signal transmitting unit. The signal transmitter receives the report message from two or more terminals.

Abstract:
A photoresist composition, a method for forming a pattern by using the composition, and an ink-jet print head using the composition are provided to inhibit the generation of crack due to internal stress and to improve heat resistance, chemical resistance and adhesion. A photoresist composition comprises an oxetane-containing compound represented by the formula 1 or 2; an oxirane-containing compound represented by the formula 3 or 4; a photoinitiator; and a solvent, wherein Q1 to Q8 and Z1 to Z8 are independently H, a hydroxyl group, a carboxyl group, a substituted or unsubstituted C1-C30 alkyl group, a substituted or unsubstituted C2-C30 alkenyl group, a substituted or unsubstituted C2-C30 alkynyl group, a substituted or unsubstituted C1-C30 alkoxy group, a substituted or unsubstituted C4-C30 aliphatic hydrocarbon ring, a substituted or unsubstituted C6-C30 aryl group, a substituted or unsubstituted C3-C30 heteroaryl group, a substituted or unsubstituted C6-C30 aryloxy group, a substituted or unsubstituted C6-C30 acyl group, or a substituted or unsubstituted monovalent group containing an ether bond.
Abstract:
PURPOSE: A method for servicing an album preparation using a communication line is provided to produce a digital album in an opened site and to publicize the album for other person to read the album by using a communication network. CONSTITUTION: A user connects to the Internet through a dedicated line and a telephone line and connects to a photo zoom site providing an album production service. The user is authorized by a user certification program(S604). An album is produce using an album production tool being provided from the photo zoom site(S606). A memory space is allocated to a member for storing the produced album. The album production tool includes a user certification, a possibility of a preparation of an album, outputting and modifying initial album information, preparation of a page format, an album displaying selection, a photograph up-loading, a photograph deleting, a sound up-loading, a memo up-loading, a lay-out changing, and a background selection. The produced album is stored(S608). The stored album is read(S610).
