Abstract: There is provided a biliary atresia diagnosis support management system including a server, the server including a transmission/reception unit receiving an image of stool from a living body and a determination unit determining whether biliary atresia is contracted or not from the image, wherein the server further includes: a management unit including a usage fee saving unit saving received usage fees and a donation sending unit for sending a donation from the saved usage fees; and a doctor's determination request processing unit requesting a determination by a doctor if the determination unit determines that there is a suspected positive result; and if it is diagnosed that the living body needs treatment for biliary atresia as a result of a thorough examination, the server pays a donation for the treatment from the usage fees saved in the usage fee saving unit via the donation sending unit.

Abstract: A polymer pyroelectric infrared sensor having an improved sensitivity and an improved heat resistance is formed by disposing a pyroelectric film having electrodes for taking out a pyroelectric output on both sides so as to face a window for introducing infrared rays. The pyroelectric film comprises a pyroelectric film of vinylidene fluoride copolymer having a crystallinity of 60% or more and a relative dielectric constant of 10 or below at 25.degree. C. and in a low frequency region of 0.1-10 Hz.

Abstract: A pyroelectric infrared detector or infrared ray receiving element comprising a plurality of pyroelectric operating areas, utilizing one of the operating areas as an infrared radiation detection area having a light-transmissive surface electrode. The electrical signal produced in the signal detection area is compensated by an electrical signal produced in another pyroelectric operating area having a light-reflective surface electrode. Temperature drift and noise due to vibration are drastically reduced through the compensation.
