Abstract: According to one embodiment, a processing system estimates a pose of a worker based on a first image in which the worker and an article are visible. The processing system estimates at least one selected from a state of the article and a work location of the worker on the article, based on the first image. The processing system generates first graph data including a plurality of nodes and a plurality of edges, based on the pose and the at least one selected from the state and the work location. The processing system inputs the first graph data to a neural network including a graph neural network (GNN). The processing system estimates a task being performed by the worker, by using a result output from the neural network.

Abstract: According to one embodiment, a processing system generates first graph data based on a pose of a worker. The pose is estimated based on a first image of the worker. The first graph data includes a plurality of first nodes corresponding respectively to a plurality of joints of the worker, and a plurality of first edges corresponding respectively to a plurality of skeletal parts of the worker. The processing system inputs the first graph data to a neural network including a graph neural network (GNN). The processing system estimates a task being performed by the worker, by using a result output from the neural network.

Abstract: The present invention is a process to express a target peptide in a large amount and accumulate the target peptide in host cells in the form of inclusion bodies. The process comprises:A) culturing host cells transformed with a plasmid able to express a gene coding for a fusion protein represented in the formula A--L--B, wherein B is a target peptide, A is a protective peptide comprising a 90-210 amino acid fragment E. coli .beta.-galactosidase, and L is a linker peptide positioned between the C-terminus of the protective peptide and the N-terminus of the target peptide and selected so that when the fusion protein is treated by an enzyme or chemical substance, the target peptide is separated, and wherein the protective peptide and linker peptide are selected so that the isoelectric point of the fusion protein in between 4.9 and 6.
