Abstract: An atelocollagen according to an embodiment is characterized in that, when analyzed by high-performance liquid chromatography (HPLC), a peak area (S?) for a ? chain is larger than a second peak area for an ? chain (S?2) so that, when a physiologically active material is loaded therein, the atelocollagen may decrease rapid initial release of the physiologically active material or may control reduction in effects of the physiologically active material due to too slow initial release. Further, the atelocollagen of the present invention may exhibit excellent cancer metastasis inhibitory effects.

Abstract: One aspect according to the present disclosure relates to a novel nucleic acid ligand which is a new class of nucleic acid compound, the existence of which was considered impossible in the prior art. The novel nucleic acid ligand has specific binding affinity with respect to at least two different targets having three-dimensional structures, and the binding sites for the at least two targets are formed in or from a single nucleic acid ligand. The novel nucleic acid ligand according the present disclosure can simultaneously solve several problems of existing aptamers that the prior art could not solve. One aspect according to the present disclosure relates to a novel screening method for identifying the above-mentioned novel nucleic acid ligand. The novel screening method uses a step for sequentially contacting at least two different targets having three-dimensional structures to screen a novel nucleic acid ligand that was previously thought impossible.

Abstract: Security check methods and systems over a user on a vehicle may be provided. The security check method including checking an allowed security right to a destination of a vehicle for entry, detecting a security right of a user on the vehicle, and performing a security process related to getting off the vehicle, based on the security right of the user and the allowed security right may be provided.
