Abstract: The present disclosure relates to a brake disc including a braking part having a circular plate shape having a hollow portion and a plurality of coupling portions protruding and extending from an inner diameter surface thereof, and a hat part disposed in the hollow portion and having a plurality of insertion portions protruding laterally, in which the plurality of coupling portions is respectively coupled to the plurality of insertion portions, and the coupling portion of the braking part and the insertion portion of the hat part are joined to only one of an outboard portion or an inboard portion of the braking part. According to the present disclosure, it is possible to reduce noise occurring at a position at which the hat part and the braking part are coupled to each other and improve cooling performance.

Abstract: Disclosed are a matrix for restoring soft tissue and a method of producing the same, the method including: forming a sheet-type absorption layer (11) on one side of a double layer using biocompatible neutral collagen; forming a film-type support layer (12) on the remaining surface of the double layer by mixing collagen with a water-soluble polymer and a natural material; and forming a double layer-structured matrix (10) for restoring soft tissue by attaching the absorption layer (11) and the support layer (12) so as to treat damage to soft tissue of a mammal other than a human or restore damaged soft tissue. This invention pertains to the treatment of damage to soft tissue such as tendons, ligaments, and rotator cuffs or the restoration of damaged soft tissue, whereby the quality and reliability of products can be remarkably improved, thus satisfying various needs of consumers, who are the users thereof, and exhibiting a good effect.

Abstract: A method and an apparatus for supporting a discontinuous reception (DRX) operation in a Node B in a mobile communication system are provided. The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.
