Abstract: A log management device includes one or more memories configured to store management information indicating each relationship between identification information of each virtual machine and identification information regarding each environment in which the each virtual machine operates, and one or more processor coupled to the one or memories and configured to, by referring to the management information, obtain a first log regarding a first environment operating a first virtual machine on the basis of identification information of the first virtual machine, perform generation of a second log in which specific information included in the first log is changed to a specific identifier regarding the first environment, and output the second log in response to receiving a request for a log regarding the first virtual machine.

Abstract: An X-ray imaging device 1 includes a back-illuminated solid-state image pickup element 10 including an X-ray detection section having a plurality of detection pixels arrayed for detecting incident X-rays formed on one surface 11 side, and an X-ray incident surface on the other surface 12, and a shielding layer 20 provided on the incident surface 12 of the image pickup element 10 and to be used for blocking light rays with wavelengths longer than the wavelength of X-rays as a detection target. The shielding layer 20 includes a first aluminum layer 21 provided directly on the incident surface 12, a second aluminum layer 22 provided on the first aluminum layer 21, and an ultraviolet light shielding layer 25 that is provided between the first and second aluminum layers 21 and 22 and is used for blocking ultraviolet light rays. Accordingly, an X-ray imaging device capable of suppressing the influence of detection of noise light in X-ray detection is realized.
