Abstract: Provided is a technology for executing information processing with respect to a risk calculated in order to grasp a frequency at which an accident occurs in equipment included in a plant, in a manner that facilitates utilization in safety management of operation of the plant. With regards to processing of maintenance management information of a plant for processing fluid, a plan view of the plant is displayed divided into a plurality of blocks, based on risks of a plurality of accidents assumed to have a possibility of occurring in a plurality of pieces of equipment included in the plant. The plan view is displayed on a monitor with assessment information indicating a result of assessing a risk level attached to each of the blocks. A three-dimensional image about equipment included in a block selected from the plurality of blocks is further displayed on the monitor.

Abstract: The present invention is a heterocycle-containing amino acid compound represented by a general formula (1): wherein R1 and R2 are identical with or different from each other, and each represent a hydrogen atom or a carboxy-protecting group; R3 represents a carboxyl group or a hydroxyl group; and n is 1 or 2, or a salt thereof.
