Abstract: The composition of the present invention induces changes in the composition of gut microbiota, particularly changes in the composition of Desulfovibrionasaceae strains, in a high glucose diet environment, so it has no toxicity to the body and has excellent brain tumor inhibitory activity, and thus it can effectively prevent, improve or treat brain tumors. Furthermore, such changes in the composition of gut microbiota in a high glucose diet environment induces a synergistic effect with anticancer drugs, particularly immune checkpoint inhibitors, and thus it can ultimately contribute to improving the survival rate of brain tumor patients.

Abstract: An image encryption method. The method includes generating an adjusted secret image by adjusting an intensity range to be the same for each RGB channel of a secret image; generating a modulated image by repeating pixel modulation in block units on the adjusted secret image; and generating an interlaced image by interlacing odd-numbered lines of the adjusted secret image with even-numbered lines of the modulated image or interlacing even-numbered lines of the adjusted secret image with odd-numbered lines with the modulated image.
