Abstract: A system, method, and computer readable medium for assembling a target assembly such as a vehicle utilize a computer-aided design (CAD). The method for assembling the target assembly includes determining a disassembly sequence of the target assembly based on a CAD assembly that modeled the target assembly, determining an assembly sequence of the target assembly based on a comparison between the disassembly sequence and an assembly sequence of a pre-stored reference assembly, and generating an operation path of an assembly machine configured to assemble the target assembly based on the assembly sequence of the target assembly.

Abstract: The current disclosure relates to a composition for promoting bone regeneration, preventing or treating bone diseases using a composition containing a hydrogel and a stem cell spheroid and a use thereof, and a method for preparing the same, wherein the composition for bone regeneration has the effect of promoting bone regeneration of injured bone tissue and alleviating pain while promoting the differentiation of the injected mesenchymal stem cells into osteoblasts and osteocytes at the same time, and thus, can be used for the prevention or treatment of bone diseases.
