Abstract: An autonomous endoscopic system capable of controlling movement of an endoscope inserted into a protective sheath installed in the body of a patient includes: an endoscope operating device capable of operating a relative position of the endoscope with respect to the protective sheath, a rolling angle of the endoscope, and a bending angle of a bending portion which is located at the end of the endoscope and is bendable; and a control unit for controlling the endoscope operating device, wherein the control unit controls the endoscope operating device on the basis of a driving record of the endoscope.

Abstract: A renal surgery training system includes: an internal calyx fluid simulation device including a supply hose configured to supply fluid, a simulator connected to the supply hose and through which the fluid supplied by the supply hose flows, a fluid receiver connected to the simulator such that the fluid flows and in which the fluid moved from the simulator is received, and an outlet hose configured to discharge the fluid stored in the fluid receiver, the internal calyx fluid simulation device configured to simulate a flow of fluid in a kidney; and a translation device disposed below the internal calyx fluid simulation device and configured to perform a translational movement to translate the internal calyx fluid simulation device, the renal surgery training system configured to provide training on removing an object swimming inside the kidney by a flow of fluid in the kidney by using training equipment.

Abstract: A scheduling method of a system on chip including a multi-core processor includes receiving a schedule-requested task, converting a priority assigned to the schedule-requested task into a linear priority weight, selecting a plurality of candidate cores, to which the schedule-requested task will be assigned, from among cores of the multi-core processor, calculating a preemption compare index indicating a current load state of each of the plurality of candidate cores, comparing the linear priority weight with the preemption compare index of the each of the plurality of candidate cores to generate a comparison result, and assigning the schedule-requested task to one candidate core of the plurality of candidate cores depending on the comparison result.

Abstract: An electronic device includes a display, a communication circuit, a processor connected to the display and the communication circuit and including a plurality of cores, a volatile memory electrically connected to the processor, and a nonvolatile memory electrically connected to the processor, wherein the nonvolatile memory is configured to store at least one application program and store instructions that cause, when executed, the processor to execute a process of preloading shared classes and/or resources of an operating system for the at least one application program, and the executing of the process includes allocating a plurality of groups of the classes and/or the resources to two or more cores among the cores, and preloading the plurality of groups of the classes and/or the resources into the volatile memory in parallel using the two or more cores.

Abstract: Disclosed is an improved air suspension that prevents damage and/or failure of a component of an air spring, such as an air sleeve, by unwanted force or moment, such as rotational torque, applied to the air spring during vehicle traveling. The air suspension includes a damper including a cylinder and a piston rod, an air spring to which a canister and an air piston are hermetically connected via an air sleeve, an upper mount which secures the piston rod and the canister to a vehicle frame, a first bearing disposed at a connecting portion between the upper mount and the piston rod, and a second bearing disposed at a connecting portion between the air piston and the cylinder. Each of the first and second bearings is a thrust bearing.

Abstract: A rear wheel toe angle control system is used as an actuator for controlling rear wheels of a vehicle. The control system is an electric-powered for rapid operation thereof, thereby providing handling stability. The left and right rear wheels are operated by the single actuator to reduce weight and manufacturing costs of a vehicle, and toe angles of the left and right rear wheels are identically controlled to improve handling stability of a vehicle.
