Abstract: An augmented reality object management server is provided. The server includes a device registration unit configured to store user information and information of a plurality of devices mapped with the user information, a message reception unit configured to receive, from a device of a first user, a request message requesting to share video contents and an augmented reality object with a device of a second user, a mode selection unit configured to select a first mode for transmitting both the video contents and the augmented reality object to the device of the second user, or a second mode for transmitting only the augmented reality object to the device of the second user, and a transmission unit configured to transmit the augmented reality object to the device of the second user based on the selected mode.

Abstract: A sintered material for a thermal barrier coating is provided. The sintered material comprises Gd2Zr2O7 doped with yttria (Y2O3). The sintered material exhibits excellent thermal barrier characteristics and has improved durability and high hardness. Therefore, the sintered material is used to form thermal barrier coatings on the surfaces of a variety of machine parts, thereby achieving high reliability and increased lifetime of the machine parts.
