Abstract: An image-based livestock inventory management device includes a data transmission and reception module, a memory storing an image-based livestock inventory management program, and a processor configured to execute the image-based livestock inventory management program stored in the memory, wherein the image-based livestock inventory management program detects each livestock individual by inputting, to a livestock individual detection model, an image collected by at least one camera that captures a doorway of each livestock room which is set as one region of interest (ROI), tracks a movement state of each livestock individual by accumulating and storing center coordinates of detected each livestock individual, generates entry and exit state information of each livestock room by counting an entry action and an exit action of each livestock individual at the doorway of each livestock room for the ROI, and provides inventory information.

Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.

Abstract: A tire includes a reinforcing rib formed on a groove to prevent irregular wear of a tread and including an auxiliary hidden groove formed in the groove to enhance capabilities of water absorption and drainage of the tire even when the reinforcing rib is formed on the groove. The tire can include a reinforcing rib coupled to a first sidewall, which is one of both sidewalls forming the groove, and protruding toward the groove from the first sidewall, a hidden groove formed in one portion of a second sidewall which is the other of the sidewalls forming the groove, and a remaining tread part protruding toward the groove from a side surface of the hidden groove, the remaining tread part being the other portion of the second sidewall.

Abstract: The hose clamp includes a clamp body formed by bending a resilient plate-shaped member of a stainless steel material, a fastening screw having a head and coupled with a fastening housing which is secured to one end of the clamp body, and a plurality of screw holes formed inwards at the other end of the clamp body to be engaged with the fastening screw, and a compensation bead integrally formed with the clamp body for restraining and firmly fastening the hose in an amount being reduced as the diameter of the hose is decreased due to long-term use, wherein the compensation bead further includes a plastic deformation prevention means, to prevent the compensation bead from not being restored to its original state due to loss of its elasticity by a plastic deformation.

Abstract: An address resolution protocol (ARP) processing method for Ethernet matching is provided in which a message authentication code (MAC) request message including IP information is received from another application module and provides a MAC corresponding to the MAC request message, the method including: determining whether a MAC matching the IP information included in the MAC request message is stored; determining whether the MAC request message includes Ethernet over synchronous optical network/synchronous digital hierarchy (SONET/SDH) (EoS) channel information; if it is determined that the MAC request message does not include EoS channel information, detecting EoS channel information that is previously stored and that matches the IP information; and broadcasting an ARP request message to an external host via an EoS channel. The ARP processing method is performed using the EoS channel, thereby reducing unnecessary broadcast traffic packets.
