Abstract: The present invention relates to an influenza virus production method using a disposable culture process system, and a test for quickly checking conditions for influenza virus antigen purification. According to the present invention, conditions for influenza surface antigen obtainment (purification) may be quickly and reliably checked according to the unique method of the present invention, even without using the single radial immunodiffusion technique which is conventionally used as a standard test method when producing influenza vaccines, and thus the production time for an influenza surface antigen subunit vaccine is notably reduced, thereby enabling quick response as a result of rapid vaccine development/manufacturing, even in a rapid novel influenza pandemic situation.

Abstract: Provides an apparatus for detecting variants of malicious code based on neural network learning, a method therefor and a computer readable recording medium storing a program for performing the method. According to the present invention, one-dimensional binary data is converted into two-dimensional data without separate extraction of features, and deep learning is performed through a neural network having a nonlinear multilayered structure, such that the features of the malicious code and variants thereof may be extracted by performing the deep learning. Therefore, since no separate feature extraction or artificial effort by an expert is required, an analysis time is reduced, and variants of malicious code that cannot be captured by existing malicious code classification tools may be detected by performing the deep learning.
