Abstract: The present disclosure relates to a method for carrying out dose delivery quality assurance for high-precision radiation treatment, in which parameters affecting a pass rate of dose delivery quality assurance can be derived through regression analysis, which is a known statistical analysis method, and a pass rate prediction model capable of predicting each parameter and the pass rate of dose delivery quality assurance can be derived, and accordingly, it can be predicted in advance whether dose delivery quality assurance will be passed according to the parameters through the above prediction model, without repeatedly carrying out dose delivery quality assurance according to a patient's treatment plan, and as a result, the efficiency of dose delivery quality assurance can be enhanced, and the time or capacity required for such quality assurance is reduced, such that radiation treatment for an actual patient can be quickly and precisely carried out.

Abstract: A fuel cell system includes at least one electricity generating unit for generating electric energy through an electrochemical reaction between oxygen and hydrogen, a reformer for reforming fuel to generate hydrogen gas to be supplied to the electricity generating unit, a fuel supply apparatus for absorbing a liquid fuel stored in a fuel reservoir and supplying the fuel to the reformer and an oxygen supply source for supplying oxygen to the electricity generating unit. The fuel supply apparatus employs an absorber with capillary channels in which osmotic pressure is produced due to a concentration differential caused by thermal energy. The osmotic pressure allows the fuel to flow.
