Abstract: Provided is a resource label retrieval method in a one M2M system. A resource information retrieval method according to an embodiment of the present disclosure includes retrieving, by the M2M system, labels of resources when a label retrieval request regarding resources is received, determining, by the M2M system, whether to return an interworking information label on which information regarding data interworking with another system is recorded, among the retrieved labels of the resources, and returning a label of a resource retrieved according to a result of the determining. Accordingly, when retrieval of a resource label is requested, an interworking information label is selectively/restrictively returned based on a type of an AE which requests or a type of a retrieval request, so that a service error caused by provision of unnecessary information can be prevented and information security can be strengthened.

Abstract: A seat for a vehicle having a fold-and-dive function is proposed. When a seatback is rotated forwards and folded, a seat cushion is moved down, so the fold-and-dive function of the seat is realized. When a full-flat mode is realized by the reclining operation of the seatback, a rear end of the seat cushion is moved up, so a step between the seat cushion and the seatback can be significantly reduced or eliminated. Furthermore, a front link connecting a back cushion interlocking frame and a cushion fixing bracket to perform the fold-and-dive function is installed to have directivity where it is inclined rearwards, thus preventing a submarine phenomenon of the seat in the event of a forward collision.
