Abstract: A sharing system includes an operation channel of a block chain that shares operation data including information on a construction failure of a resource used in a service provided to a customer among a plurality of nodes, a provision channel of the block chain for sharing provision data used for providing information on a predetermined construction failure for the resource to the customer among a plurality of nodes, a monitoring unit that participates in the operation channel and the provision channel and monitors for construction failures of the resource, a maintenance node including an update unit configured to update a detection state of construction failures in the provision data when detecting update of the state of the construction failure related to the provision channel to be participated, and a provision node that participates in the provision channel and includes a notification unit.

Abstract: The present invention provides an apparatus for extracting nucleic acid from a specimen, including traditionally difficult specimens, in preparation for polymerase chain reaction (PCR) analysis. The apparatus includes: a shaker, a centrifugal separator, a particle supply mechanism for supplying particles of different sizes, a liquid chemical supply mechanism, a conveyance arm for transporting the specimen or tube-containing specimen, and a control means. The control means is designed to shake tubes containing large and small diameter particles and transport the tubes through a centrifuge in order to separate the nucleic acid-containing material from the remainder of the specimen and crush the material to extract the nucleic acid.

Abstract: An object of the present invention is to provide a nucleic acid extraction apparatus which extracts a nucleic acid from a specimen from which it has conventionally been considered difficult to extract the nucleic acid, such as feces or sludge, and thereby allows analysis in accordance with a PCR method (analysis using the polymerase chain reaction) to be performed successfully.
