Abstract: Provided is a method of creating digital twin content for a space based on object recognition in the space. A method of creating digital twin content includes identifying, by a computer system, an object in a space using a camera, determining a value of a parameter associated with the camera to define (or display) the identified object with a predetermined first size at a predetermined location on an image captured by the camera or a screen on which the image is displayed, and using a control result value based on the determined value of the parameter and the location information of the identified object to create the digital twin content for the space.

Abstract: Disclosed is a method of diagnosing a vehicle including an electric motor performed in the vehicle. The method includes acquiring first to third measurement values for a temperature, a voltage, and a current associated with the electric motor from one or more sensors installed for the electric motor, calculating first to third scores for a predetermined diagnostic factor based on each of the first to third measurement values, reading a weight for each of the temperature, the voltage, and the current with regard to the predetermined diagnostic factor from a database installed in the vehicle, and calculating a comprehensive diagnostic score for the predetermined diagnostic factor based on the weight for each of the first to third scores and the predetermined diagnostic factor.

Abstract: Disclosed are a method and an apparatus for an instant messaging service to provide a schedule service. A schedule management server according to an example embodiment includes receiving a schedule creating request, selecting any one of a first type of calendar belonging to a chatroom in which the schedule creating request is created and a second type of calendar belonging to a user account which creates the schedule creating request, according to a schedule type included in the schedule creating request; and creating a schedule corresponding to the selected type of calendar.
