Abstract: A power-generating method of generating power from a power-generating element. An electric polarization state in the power-generating element is changed by phase transition. First, an electric field is applied to the power-generating element to change a phase transition temperature of the power-generating element by an electric-field application unit for applying the electric field to the power-generating element without changing a temperature of the power-generating element. Then, the electric polarization state in the power-generating element is changed by application of the electric field and control of the application, so that the power from the power-generating element is generated.

Abstract: A treatment course determination assistance system is configured to perform the steps of: allowing a review applicant to input details to be reviewed through use of an input unit; displaying, by a processing server, a designated reviewer candidate involved in treatment of the patient based on information read from the patient information database; allowing the review applicant to select a designated reviewer candidate desired to perform review based on professions of displayed designated reviewer candidates; selecting, by the processing server, one or more anonymous reviewer candidates extracted randomly based on professions and/or specialties relating to the details to be reviewed from the reviewer information database; and asking the designated reviewer candidates selected by the review applicant and the one or more anonymous reviewer candidates selected by the processing server whether or not to accept a request for cooperation on review.
