Abstract: The invention provides a method for producing a peptide by (1) removing the N-terminal protective group of an amino acid or peptide compound of formula (I): wherein Y represents a residue of an N-protected amino acid or an N-protected peptide, and each of R1, R2, and R3 independently represents an aliphatic hydrocarbon group which may have a substituent or an aromatic hydrocarbon group which may have a substituent, wherein the total number of carbon atoms in the R1R2R3Si group is 18 to 80, and the R1R2R3SiCH2CH2 group is bonded to the C-terminus of the amino acid or peptide residue in Y; and (2) causing condensation of an N-protected amino acid or an N-protected peptide and the N-terminus of the C-protected amino acid or C-protected peptide obtained in the step (1).

Abstract: A three-dimensional drawing display system includes: a storage unit configured to store three-dimensional data of components that configure a ship, design information of the components, and design information of the ship; and an image generation unit configured to generate a three-dimensional image that displays the ship as an assembly of the components on the basis of the design information of the ship along with a ship body coordinate system.
