Abstract: Disclosed are new polymeric materials that respond to a mechanical force. The novel polymeric compounds contain an isomer of aziridine, a three-membered N-heterocyclic compound. Also disclosed are methods for preparing the polymeric compounds. Mechanical force-induced cycloaddition of aziridines as mechanophores yields stereospecific products without covalent bond cleavage of aziridines. That is, a mechanical force makes the mechanochemical products stereospecific. The stereospecific products prepared from the isomeric mechanophores by a mechanical force can be widely used in various industrial fields, including new materials.

Abstract: In a software watermarking method according to an embodiment, a watermark is embedded into an executable binary file by compiling a source code to generate the executable binary file and rewriting the executable binary file while reordering two or more functions included in the executable binary file. At the time of compiling the source code, metadata including information related to positions of functions in the executable binary file is generated and included in the binary. The executable binary file is rewritten by reflecting change in positions of the two or more functions using the metadata without recompiling the source code. Information related to the changed function location is stored in a separate ledger.
