Abstract: The present invention relates to a method for user image data matching in a metaverse-based office environment and, more particularly, to a method for user image data matching in a metaverse-based office environment, the method comprising: a chat group identification step of identifying a camera viewpoint of a target user in a virtual space, and identifying whether a chat group for users included in a virtual image of the camera viewpoint is included; and a user image matching step of matching user images to avatars of respective group users included in the chat group, the user images being obtained by image-capturing the group users in real time.

Abstract: The present invention relates to a method for user grouping in a metaverse-based office environment and, more particularly, to a method for user grouping in a metaverse-based office environment, the method comprising: a target user identification step of identifying a camera viewpoint of a local user in a virtual space, and identifying target users included in a virtual image of the camera viewpoint; and a user grouping step of grouping target users satisfying a configured grouping condition from among the target users, on the basis of avatar positions and gaze directions of the local user.

Abstract: Disclosed is a method for producing 3-fucosyllactose using a wild Corynebacterium glutamicum strain. In addition, using the Corynebacterium glutamicum strain, which is a GRAS strain, 3-fucosyllactose can be produced at a high concentration, high yield and high productivity.
