Abstract: Provided is a robot working in shifts, the robot including a storage unit configured to store received work plan information including a work position, work information, and workload information, and a work log created and received by a preceding work robot, a work processing unit configured to move to a work area and then work on the basis of plane information when only the work plan information is present in the storage unit, a log creation unit configured to detect workload performed through the work processing unit and work position information regarding a work position to which the robot has moved for work, create a work log including the detected workload and work position information, and store the created work log in the storage unit; a rotation determination unit configured to determine a shift rotation cycle; and a communication unit configured to establish a communication link with a subsequent robot and transfer the work log stored in the storage unit to the subsequent robot when the rotation dete

Abstract: The vehicle route prediction apparatus includes a lane recognition unit configured to recognize a type of each of a left lane and a right lane with respect to a driving vehicle, a position recognition unit configured to obtain latitude and longitude coordinates of the driving vehicle, a storage unit configured to store map data, including road information, and a route prediction model, and an arithmetic operation unit configured to check an identifier of an intersection which the driving vehicle intends to enter, based on a position of the driving vehicle and the map data stored in the storage unit, check a position of a lane, based on the type of each of the left lane and the right lane recognized by the lane recognition unit, predict a route of the driving vehicle by using the route prediction model corresponding to an ID of the intersection.

Abstract: The present invention relates to a steering control apparatus and a method of operating the apparatus. The steering control apparatus of the present invention includes a sensor unit for sensing movement of an autonomous driving vehicle or a limited autonomous driving vehicle, and calculating movement information. A determination unit determines a driver's steering intention using an actual steering torque value of the vehicle, calculated based on the movement information, and a reference value corresponding to speed of the vehicle, and decides on a driving control agent. A control unit transfers a driving control authority of the vehicle depending on the driving control agent.

Abstract: Provided is an application program launching method and system for improving security of an embedded Linux kernel by distributing superuser privileges. The method includes: searching security set information on an application program selected by a user; changing a user account for a processor of the application program to a user ID associated with the application program in the security set information; setting a capability for the processor according to setting information for the capability in the security set information; changing a basic directory for the processor according to a basic directory in the security set information; and launching the application program.

Abstract: Provided is a method capable of providing an improved response property appropriate for the characteristics of a system by automatically choosing an interrupt handling mode used for each device. The method is a method in which the embedded operating system kernel determines a handling mode for all individual interrupts, the method includes: dividing interrupt handling modes into a first interrupt handling mode and a second interrupt handling mode which has a different process speed from the first interrupt handling mode, and variably determining a distribution ratio in which each of the interrupts are distributed to the first interrupt handling mode or to the second interrupt handling mode according to a predetermined process condition during boot-up.

Abstract: Provided is a method for transmitting contents with limited system permissions. In the method, a content request is received from a client terminal. A download descriptor is transmitted to the client terminal in response to the content request, the download descriptor including information about the authentication and permission of the client terminal system that can be managed in the contents. A content transmission request is received from the client terminal that has received the download descriptor. Contents are transmitted to the client terminal in response to the content transmission request.

Abstract: A method of task assignment in a distributed processing system including a plurality of processors is proposed. The method of task assignment includes calculating utilities of tasks to be processed in execution units included in each processor and arranging the calculated results in descending order; calculating utility difference values between the execution units included in each processor and outputting a highest difference value; comparing a utility of the task with the output highest difference value; designating the task to be assigned to the execution unit having the lowest utility in a processor in which the highest difference value is generated when the utility of the task is less than or equal to the output highest difference value; repeating the calculating, comparing, and designating in the order of the arranged tasks; and assigning the tasks to the designated targets.
