Abstract: A vehicle-to-everything (V2X) communication-based electronic toll collection system (ETCS) according to an embodiment of the present invention includes at least one roadside unit (RSU), a token issuer checking a de-identified token of a vehicle by communicating with an on-board unit (OBU) of the vehicle via the at least one roadside unit, and a clearing house communicating with the token issuer and charging a toll to a driver/owner of the vehicle. The token issuer generates toll information of the vehicle based on the de-identified token of the vehicle and location information of the at least one roadside unit involved in checking the de-identified token.

Abstract: Disclosed is a method and apparatus for detecting anomalies in a system log on the basis of self-supervised learning, using a language model. The method comprises performing preprocessing on the system log, generating a normal token sequence having a preset length by concatenating tokenized log lines of the system log, generating an abnormal token sequence using the normal token sequence, calculating an anomaly score for a determination target token sequence using a sentence classification model, and determining the token sequence as an abnormal system log when the calculated anomaly score is greater than a threshold value.

Abstract: A device for secure and automated enrollment-certificate bootstrapping on keys and certificates for a vehicle to everything (V2X) environment of a V2X end entity in a security credential management system (SCMS) for V2X communication, the device comprising: a processor; and a memory configured to store at least one instruction to be performed by the processor, the at least one instruction is configured to instruct the processor to perform steps of: by a secure bootstrapping service (SBS) agent, checking, for an SSB server, configuration information; by the SBS agent, making a request for bootstrapping data to the SBS server; and by the SBS agent, installing the bootstrapping data in the SBS server.

Abstract: A method for managing an enrollment certificate in an SCMS for V2X communication may comprise receiving a message requesting an authority for generating a CSR from a DCM; updating device certification data through a certification laboratory that manages performance and requirements of an EE, and verifying the EE that requested issuance of an enrollment certificate to the DCM by using the updated device certification data; transmitting response data indicating the authority for generating a CSR to the DCM based on a result of the verification; receiving a CSR generated according to the response data from the DCM; and verifying the received CSR, and requesting response data for the CSR to an ECA based on a result of the verification.

Abstract: The present invention relates to a shoe and a manufacturing method thereof, wherein the invention comprises: a shoe upper; a bottom sole for blocking the lower part of the shoe upper; and a sole cover which is extended from the lower part of the upper of the shoe, and enhance the circumference of a sole, wherein an edge of the bottom sole and a lower edge of the sole cover are connected along a lower edge of the upper of the shoe by backstitching, the sole is attached to a lower side of the bottom sole, the sole cover is turned inside out to face the sole such that the sole cover is attached to enclose an outer surface and a lower edge of the sole, and a window is attached to a lower side of the sole including the end of the sole cover.

Abstract: Provided is an error measurement and correction device of a stage of a wafer prober. The error measurement and correction device includes a jig member, a vision module, a central processing unit, and an interface unit. The jig member is disposed on a chuck on the stage, and the vision module is disposed on an upper plate of the wafer prober disposed at a position facing the jig member to enable the camera of the vision module to acquire images of the patterns of the jig member and transmits the acquired images to the central processing unit. The central processing unit acquires images of the patterns of the jig member disposed on the chuck by using the vision module to extract reference position information, moves the stage at a unit interval of the pattern, acquires images of the patterns of the jig member again to extract measured position information, and generates and stores mapping data by calculating difference between the measured position information and the reference position information.
