A diagnostic assistance system for assisting a person in performing diagnosis of an object includes target data storage means for storing target data indicating a state of the object, diagnostic task means for providing each of a first user and a second user with the target data to enable each of the first user and the second user to perform a diagnostic task of the object, diagnostic result means for receiving a result of diagnosis of the object by each of the first user and the second user, and sharing means for enabling the first user and the second user to share result of diagnosis by each of the first user and the second user. The diagnostic task includes a first sub-task of investigating the target data to output a first diagnostic result and a second sub-task of using the first diagnostic result to output a second diagnostic result.

Diagnostic assistance system and method therefor

The present invention makes an efficient diagnosis of an object. A general serverof a diagnostic assistance systemprovides data (a large volume of photographic images) concerning an object managed by each client, to said client and a plurality of analysts and experts, and allows such diagnosers to diagnose the object and enables sharing of diagnosis results among the diagnosers. The plurality of analysts each partially contribute in viewing the large volume of photographic images so as to find an abnormal site in the object. The client and the experts then conduct a more detailed diagnosis on the abnormal site discovered by the analysts. An AI serverof the diagnostic assistance systemcreates training data from the diagnosis results provided by the plurality of diagnosers, performs machine learning on the diagnosis results, and carries out automated diagnosis using the learned method.

A method for processing data performed in a data processing system having a storage unit is provided which includes: creating a spatial index comprising a leaf containing location information and attribute information with respect to a plurality of objects to be searched, and storing the spatial index in the storage unit; and referring to the spatial index stored in the storage unit in response to an input of a search request including location information and attribute information for searching the object to be searched, and extracting the object to be searched that agrees with the search request. With this configuration, a spatial search with subsidiary condition search can be processed at high speed, without merging results of both searches.

Method and system for data processing with spatial search

A conductive material and an oxazoline ring-containing compound or a high-molecular compound obtained by (graft) copolymerization of at least one 2-oxazoline ring-containing compound are added to an aromatic polycarbonate resin and optionally a polyester resin having mainly a skeleton of 1,4 cyclohexanedimethanol origin as a glycol component, thereby obtaining a conductive resin composition significantly improved in strength characteristics and further moisture absorbability without deterioration of heat resistance.

Conductive resin composition

A core construction of a nuclear reactor wherein the fuel charge in the core has 1/4 symmetry and fuel assemblies adjacent a control rod (10) constitute a core unit. In the central portion of the core, each core unit (12) is composed of one thrice burned fuel assembly (3), and three once (1) or twice (2) burned fuel assemblies. One of the two types of fuel assemblies which includes two fuel assemblies located on a diagonal line in the respective core unit. In the core as a whole, the fuel assemblies of the same type or the same burning cyclic period are located on a diagonal line (E,F,G).
