Abstract: The present disclosure relates to a polycarbonate resin composition, and more particularly, to a polycarbonate resin composition containing 90 wt % to 99 wt % of a polycarbonate resin, 0.3 wt % to 0.7 wt % of an anthraquinone-based black dye, and 0.2 wt % to 1.0 wt % of an acrylic polymeric chain extender, and a molded article containing the same.

Abstract: According to one embodiment, a method by which a device provides a service so as to enable cognitive function rehabilitation by using a virtual object model comprises the steps of: generating a virtual object model in a virtual space matched to correspond to a real space where a subject is located; generating a plurality of first preliminary stimuli for identifying egocentric neglect in the visual range of the subject on the basis of the virtual object model; obtaining and collecting first reaction information about whether the subject has recognized the first preliminary stimuli; determining an egocentric cognition range in which the subject can egocentrically recognize visual stimuli on the basis of the first reaction information; sequentially generating a plurality of second preliminary stimuli for identifying allocentric neglect in the egocentric cognition range on the basis of the virtual object model; obtaining and collecting second reaction information about whether the subject has recognized the secon

Abstract: The present disclosure relates to an authentication device using DNA base sequence information, the authentication device including an authentication means, in which a plurality of DNA base sequence information are included in authentication information derived by reading out the authentication means composed of a plurality DNAs.

Abstract: The present disclosure relates to an authentication device related to an NFT using DNA base sequence information, the authentication device including: an authentication means provided in a medium; a Non-Fungible Token (NFT) in which an inherent recognition value about the medium is stored; first authentication information input to the NFT; and second authentication information derived by reading out the authentication means composed of a plurality of DNAs, in which an authentication value authenticated on the basis of the second authentication information to an authentication value authenticated on the basis of the first authentication information is in a predetermined range.

Abstract: The present invention relates to a method for giving points according to virtual currency remittance, the method comprising the steps of: (a) withdrawing a virtual currency having a certain value from a virtual currency remittance account of a sender on an exchange server and then depositing a virtual currency having a value equal to the certain value into a virtual currency receiving account of a recipient on the exchange server; and (b) calculating points by applying a preset point ratio to the virtual currency having the certain value in step (a) on the exchange server and depositing a variable virtual currency for points corresponding to a value equal to the value of the points into a variable virtual currency receiving account of the sender, wherein the variable virtual currency for points is a variable virtual currency selected from various kinds of variable virtual currencies preset on the exchange server.

Abstract: A navigation terminal includes a path controller configured to identify moving trajectories reaching respective points of interest, to cluster the identified moving trajectories into at least one moving section, to reflect a road correction mechanism in the at least one clustered moving section and to cluster the at least one clustered moving section into at least one moving path, and to extract one moving path, in which time sequential position information received from a GPS is corrected, from the at least one clustered moving path. Thereby, the navigation terminal is resistant to error of a GPS sensor, error generated due to a collection cycle, or error generated in correction, and precisely predicts a moving path.
