Abstract:
The present invention relates to nanomicelles composed of a complex of a lipophilic compound and a poly-gamma-glutamic acid wherein a portion of carboxyl groups are substituted with an amine group, and more particularly, to nanomicelles composed of a complex of a lipophilic compound and a poly-gamma-glutamic acid wherein a portion of carboxyl groups are substituted with an amine group, a preparation method thereof, and a drug delivery system employing the mucous membrane-adhesive property of the nanomicelles. According to the present invention, the nanomicelle drug delivery system based on poly-gamma-glutamic acid that is a natural biopolymer can be used for the delivery of a drug to mucous membranes to thereby increase the in vivo stability and effectiveness of the drug.
Abstract:
Method and apparatus for providing traffic information to personal mobility (PM) vehicle are provided. A computer implemented method includes receiving, from a PM vehicle, at least one of Received Signal Strength Indicators (RSSIs) or Time-of-Flight (ToF) values of vehicle-to-everything messages (V2X messages) generated from roadside units (RSUs) and received by the PM vehicle, and receiving identification information and transmission time points included in the V2X messages. A position and a prediction route of the PM vehicle are deduced based on at least one of the RSSIs or the ToF values, the identification information, and the transmission time points. Then, one or more essential traffic lights among a plurality of traffic lights are determined according to the position and the prediction route of the PM vehicle and identification information of the one or more essential traffic lights is transmitted to the PM vehicle.
