An embodiment of the present disclosure provides an extrusion device 100 capable of employing a composite input method, wherein the device 100 includes: a main body unit 110 that forms an exterior and has a material input unit 120 formed at an upper portion thereof; an extrusion unit 101 including a pair of extrusion screws 155 provided inside the main body unit 110; and a conical extrusion unit 102 that is movably provided on one side of the main body unit 110 and selectively enables a raw material input into the material input unit 120.

Provided are a method and device for processing ambient Internet of Things (IoT) data in a wireless communication system. The device receives a paging message including first device identification information, and checks whether the first device identification information matches second device identification information stored in the device. Further, based on a result of the checking, the device transmits a medium access control (MAC) message including upper layer data, wherein the paging message includes a first security parameter and information indicating presence of the first security parameter.

Provided are a method and device for ambient IoT communication in a wireless communication system. The device receives a paging message including first ambient internet of things (AIoT) device identification information, and forwards the first AIoT device identification information included in the paging message to an upper layer. Further, the device receives, from the upper layer, an indication regarding whether the first AIoT device identification information matches. The paging message includes a predetermined field, and based on the predetermined field, the first AIoT device identification information may be forwarded to the upper layer.

Provided are a method and device for processing a medium access control (MAC) message in a wireless communication system. The device receives a first MAC message for paging, and after receiving the first MAC message, transmits a second MAC message including device to reader (D2R) upper layer data. Further, after transmitting the second MAC message, the device receives a third MAC message including reader to device (R2D) upper layer data. Here, the first MAC message includes device identification information and information indicating presence of the device identification information, and the third MAC message includes information indicating presence of the R2D upper layer data.
