An avatar creation method according to example embodiments includes analyzing an image including a human face and automatically creating an animal-shaped avatar corresponding to the human face.

Abstract: A non-transitory computer-readable recording medium may storing instructions that, when executed by a processor, cause the processor to set a communication session for a conference in which a plurality of users participates through a server, transmit, to the server, an identifier of an avatar to be represented on a virtual space for the conference and coordinate information of the avatar in the virtual space, receive, from the server, resources of neighboring avatars selected based on the coordinate information, transmit, to the server, motion data of the avatar through the communication session, receive, from the server, motion data of the neighboring avatars through the communication session, and represent the neighboring avatars on the virtual space based on the resources of the neighboring avatars and the motion data of the neighboring avatars.

Abstract: A semiconductor device includes a first interlayer insulating film disposed on a substrate and having a first trench. A first lower conductive pattern fills the first trench and includes first and second valley areas that are spaced apart from each other in a first direction parallel to an upper surface of the substrate. The first and second valley areas are recessed toward the substrate. A second interlayer insulating film is disposed on the first interlayer insulating film and includes a second trench that exposes at least a portion of the first lower conductive pattern. An upper conductive pattern fills the second trench and includes an upper barrier film and an upper filling film disposed on the upper barrier film. The upper conductive pattern at least partially fills the first valley area.

Abstract: The present invention provides wear-resistant steel which has high hardness while having wear resistance and high impact toughness at low temperature, and a manufacturing method therefor.

Abstract: A non-transitory computer-readable recording medium storing instructions that, when executed by a processor, cause the processor to set a communication session in which a plurality of users participate through a server, generate data for a virtual space, share motion data related to motions of the plurality of users through the communication session, generate a video in which avatars following the motions of the plurality of users are represented in the virtual space, based on the motion data, and share the generated video with the plurality of users through the communication session.
