Abstract: An active energy ray-curable lithographic printing ink including a rosin-modified resin (A), an active energy ray-curable compound (B), a photopolymerization initiator (C), and an extender pigment (D), where the active energy ray-curable compound (B) includes dipentaerythritol hexaacrylate (B1), and an amount of the dipentaerythritol hexaacrylate (B1) relative to a total mass of the active energy ray-curable lithographic printing ink is within a range from 20 to 37% by mass. The photopolymerization initiator (C) includes at least two types of compounds selected from acylphosphine oxide-based compounds (C1), thioxanthone-based compounds (C2), and oxime ester-based compounds (C3), an amount of the extender pigment (D) relative to a total mass of the active energy ray-curable lithographic printing ink is within a range from 0.1 to 10% by mass, and a viscosity of the ink at 25° C. is within a range from 10 to 120 Pa·s.

Abstract: A failure sign detection system 100 includes: a data storage unit 160 that retains data at the time of normal operation of each action, as learning data, with respect to a manufacturing operation of a manufacturing apparatus 2 composed of a plurality of actions; a sensor (acceleration sensor 6) that measures the manufacturing operation of the manufacturing apparatus 2; an action detection unit 110 that detects an action start of each action in the manufacturing operation; a divided data collection unit 180 that divides measured data, which is measured by the acceleration sensor 6, into divided data for each action and collects the divided data; and a data analysis unit 140 that analyzes an abnormality of each action on the basis of a comparison between the divided data and the learning data of each action.

Abstract: To design parameters for building a system quickly, it is provided a design assisting system, comprising: a processor configured to execute a program; and a memory configured to store the program to be executed by the processor. The memory is configured to store a plurality of parameter sets for defining usage of resources of a computer system on which a business operation is run. The processor is configured to: calculate a resource value score of each resource for each of the plurality of parameter sets, based on information for defining items to be taken into account in system designing; sum up the calculated resource value scores for each of the plurality of parameter sets separately; and determine a priority level of each of the plurality of parameter sets, based on the resource value scores summed up for each of the plurality of parameter sets separately.
