Abstract: The present disclosure relates to an image encoding/decoding method for a machine and a device therefor. An image encoding method according to the present disclosure includes extracting an encoding method feature from an encoding input signal; determining an encoding method that is optimal for the encoding input signal based on the encoding method feature; transforming the encoding input signal based on the encoding method; and encoding an encoding target signal generated by transforming encoding method information and the encoding input signal.

Abstract: The present invention relates to a Lactobacillus sakei CVL-001 strain and a method for isolating same, wherein the strain is lactic acid bacteria which can be isolated from kimchi, and thus can be effectively used as a probiotic or food additive. Furthermore, the present invention relates to a composition for improving, preventing, or treating bone diseases or metabolic diseases, including Lactobacillus sakei CVL-001 strain (Lactobacillus sakei) or a culture medium thereof, wherein the Lactobacillus sakei strain isolated from kimchi and the culture medium thereof exhibit the effects of suppressing osteoclast differentiation, improving osteoporosis, suppressing adipocyte differentiation, and suppressing weight gain, and thus can be effectively used for the improvement, prevention, or treatment of osteoporosis or obesity related diseases.

Abstract: Provided is a vehicle capable of efficient storage medium management by differentially storing images acquired by the vehicle on the basis of a surrounding environment of the vehicle and a vehicle state, and a control method thereof. The vehicle includes a storage, a camera configured to acquire a vehicle surrounding image of a vehicle, a sensor unit configured to acquired vehicle information of the vehicle, and a control unit configured to determine an accident occurrence probability of an accident occurring to the vehicle on the basis of at least one of the vehicle surrounding image and the vehicle information, and in response to determining that a collision has occurred to the vehicle on the basis of the vehicle information, determine a storage form of the vehicle surrounding image on the basis of the accident occurrence probability and store the vehicle surrounding image in the storage.

Abstract: A device-to-device (D2D) communication method is provided. According to an inventive concept, the method comprises, storing, by a first device, first authentication data including a hash chain, which is a sequential concatenation of hash values, and storing, by a second device, second authentication data including an initial hash value of the hash chain, transmitting, by the first device, a final hash value of the hash chain to the second device, determining, by the second device, whether authentication between the first and second devices has succeeded by repeatedly hashing the initial hash value stored in the second device until a hash value identical to the final hash value is returned, and if a determination is made that authentication between the first and second devices has succeeded, performing, by the first and second devices, a connection establishment process for establishing a connection between the first and second devices.
