Abstract: An example electronic device includes a display, a communication circuit, a memory, and at least one processor configured to, based on a signal for requesting transmission of identification information including a call word for using first mode of an artificial intelligence assistant function of the electronic device being received, from another electronic device, through the communication circuit using first communication method, control the display to display a user interface for requesting user confirmation for transmission of the identification information; control the communication circuit to transmit the identification information to the another electronic device as a result of user confirmation through the user interface; and receive information for using a second communication method from the another electronic device.

Abstract: The present disclosure relates to a vibration control device and a frequency-sensitive shock absorber having the same. A vibration control device includes a sub-piston rod coupled to an end of a piston rod, a pilot valve unit penetrated by and coupled to the sub-piston rod, in which pressure is formed by a fluid introduced through the sub-piston rod, and a fixing member located in a lower portion of the pilot valve unit and fastened to the sub-piston rod to fix the pilot valve unit, wherein the pilot valve unit comprises a free-piston provided to reciprocate in a vertical direction according to a change in the pressure formed by the fluid.

Abstract: An apparatus for supporting learning of a user is provided. The apparatus extracts, from a problem image, a first layout including textual information and a second layout including illustrative information, determines a first similarity between the first layout and textual information of a second problem stored, determines a second similarity between the second layout and illustrative information of the second problem, determines a third similarity between the first problem and the second problem by combining the first similarity and the second similarity, determines whether the second problem corresponds to the first problem, and transmits information indicating an answer or solution corresponding to the second problem to the user device.
