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: Disclosed is a mobile terminal having a time shift function and a method of implementing the same. The mobile terminal includes: a transceiver unit for receiving multimedia data through a wireless channel; a control unit for controlling the mobile terminal to store the multimedia data and to transform stored multimedia data into image and voice data after passing a predetermined length of time; a display unit for receiving the image and voice data and displaying the image and voice data; a keypad input unit for receiving the time shift selection signal; and a memory unit for storing the multimedia data and transmitting stored multimedia data to the control unit by the control unit. The effect of the present invention is such that a motion picture and live broadcast can be watched on the screen of the terminal at a later time as if they are currently being broadcasted.
