Abstract: Provided is a method for generating a virtual environment to verify autonomous driving service, which is executed by one or more processors and includes generating a high-precision road map of a specific area using a Mobile Mapping System, generating a first mesh associated with a road in the specific area based on point cloud data of the generated high-precision road map, generating a second mesh associated with a terrain of the specific area, and generating a virtual environment by matching the first mesh and the second mesh.

Abstract: An example image forming apparatus includes a main body, a driving motor, a developing cartridge, and a clutch. The developing cartridge includes a toner container, a mounting portion to receive a toner refill cartridge, a toner inlet portion to connect the mounting portion to the toner container, and a toner inlet shutter to be switched between a blocking location for blocking the toner inlet portion and an inlet location for opening the toner inlet portion. The clutch is to selectively transmit a driving force of the driving motor to the toner inlet shutter.

Abstract: An online system uses a visual search query to identify physical objects received from a plurality of third-party systems that match component types specified in the visual search query. The online system receives physical object information from the plurality of third-party systems and determines component types associated with the received physical objects based on the physical object information. Based on neural networks, the online system determines an index that corresponds to a component type for each component of received physical objects. After receiving a visual search query specifying component types, the online system identifies physical objects that match the visual search query for displaying to a client device.

Abstract: Provided are an apparatus and a method for providing a book recommendation service which receives information about a reader and possessing books from a user to recommend books suitable for the reader based on a keyword extracted from a recommended book by education area for the reader and a keyword obtained from the possessing books. According to the present invention, unlike a conventional method of recommending only books corresponding to an interest field of the user based on purchasing books of the user, keywords are extracted based on recommended books by education area according to an education course and then subdivided into a plurality of groups by age group or grade group based on personal information and possessing book information collected from a plurality of individuals and attributes of each group are set based on the personal information.

Abstract: The present invention relates to a method for organizing a group icon in a messenger service and, more specifically, to: a method for organizing a group icon in a messenger service, the method enabling clear confirmation of information on group members by merging the information on the members, which participate in a group chat, so as to display the information through the group icon during group chatting through a messenger service; and an apparatus therefor.

Abstract: Methods for improving the functionality and/or fertility of sperm, for example, by enhancing motility and extending the lifespan of sperm in the FRT, by adding functional molecules of interest attached to a membrane anchoring agent-PEG conjugate to the surface of the sperm are provided. Such methods may be used in AI to reduce the number of sperm needed for insemination and to improve conception rates.

Abstract: Methods for improving the functionality and/or fertility of sperm, for example, by enhancing motility and extending the lifespan of sperm in the female reproductive tract, by adding PEG to the surface of the sperm are provided. Such methods may be used in artificial insemination to reduce the number of sperm needed for insemination and to improve conception rates.
