Abstract: The present invention provides a novel copolymer available for a drug delivery technique. More particularly, a novel copolymer for a drug delivery carrier targeting a tumor is provided. The present invention relates to a copolymer comprising structural units represented by the following formulas (A), (B), and (C): wherein R1, R2, and R3 are the same or different and represent a hydrogen atom or a C1-3 alkyl group, R4 represents a C1-3 alkyl group, R5 represents a hydrogen atom, a C1-18 alkyl group, a 3- to 8-membered cycloalkyl group optionally having a substituent, an adamantyl group, a C6-18 aryl group optionally having a substituent, or a 5- to 10-membered heteroaryl group optionally having a substituent, X1, X2, and X3 are the same or different and represent an oxygen atom, a sulfur atom, or N—R7, R6 represents a hydrogen atom, a leaving group, or a linker, R7 represents a hydrogen atom or a C1-3 alkyl group, m represents an integer of 1 to 100, and n represents an integer of 0 to 3.

Abstract: An information processing apparatus includes a processor configured to: obtain plural first document images; execute classification processing for classifying each of the plural first document images, based on reliability of each of plural second document images in relation to each of the plural first document images, each of the plural second document images being preset in accordance with a classification type; and perform display control to display a first group of the plural first document images and a second group of the plural second document images on an identical screen and also to display results of the classification processing on the identical screen.

Abstract: An information processing apparatus includes a processor configured to: display on a screen a form image serving as a target that a form type is to be set to, multiple registration images, each registration image pre-registered on a per form type basis, and a setting control used to set a form type to the form image; and set on the form image a form type that a user having referenced the registration images associates the setting control with.

Abstract: A document processing apparatus includes a processor configured to: display one or more documents stored in a specific document storage area on a first screen; display a first document selected on the first screen on a second screen that receives an operation for certain document processing; and in response to storage of a new document in the document storage area during execution of the document processing, display a second document which is the new document on the second screen without receiving selection of the second document on the first screen.
