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: The present invention relates to a culture medium composition for culturing keratinocytes, and more specifically, to a culture medium composition for establishing or culturing keratinocytes, comprising calcium, an epidermal growth factor, and albumin According to the present invention, when keratinocytes are cultured using the culture medium of the present invention, the keratinocytes can be effectively proliferated within a short time, thus making it possible to more quickly obtain a desired number of the cells during the development of a therapeutic agent using the keratinocytes, and the activity of the keratinocytes is improved, and thus the culture medium of the present invention can be useful in the fields of keratinocyte research and the development of therapeutic agents.

Abstract: Disclosed herein is a method of securing keyboard input information by directly controlling a keyboard controller of a keyboard. The keyboard includes the keyboard controller, an interrupt controller, an input information processing module and a keyboard security module. The method includes a status information checking step of enabling the input information processing module to check status information of the keyboard controller; an interrupt inactivation step of inactivating an interrupt request function of the keyboard controller; an input information encryption step of encrypting the keyboard input information written to the keyboard input/output ports; a transfer step of transferring the encrypted input information to the keyboard security module; and an input information deletion step of deleting the keyboard input information remaining in the keyboard controller.
