Publication number: 20220034872Abstract: The present invention relates to a composition for repressing the sternness of stem cells, which comprises a material for regulating OCT4 modification. The material for regulating OCT4 modification according to the present invention may regulate the phosphorylation or methylation of OCT4 and inhibit Wnt signaling, thereby effectively reducing the sternness of various stem cells. Therefore, since it can be effectively used in inhibition of proliferation, recurrence and metastasis of cancer, and inhibition of resistance to an anticancer agent, and can reduce sternness even in normal stem cells, it is expected that the time for differentiation of embryonic stem cells into specific cells is shortened, and efficiency is increased.Type: ApplicationFiled: December 6, 2018Publication date: February 3, 2022Applicant: NATIONAL CANCER CENTERInventors: Hyonchol JANG, Dong Keon KIM

Publication number: 20160133206Abstract: A display device capable of substantially preventing a bruising phenomenon and a driving method thereof are provided. The display device includes a display panel which displays an image and a signal controller which controls signals for driving the display panel. The signal controller includes a first accurate color capture (“ACC”) unit which performs ACC correction on input image data to generate first correction image data; a second ACC unit which performs the ACC correction on the input image data to generate second correction image data; and an ACC selection unit which selectively applies the input image data to the first ACC unit or the second ACC unit. A maximum gray of the second correction image data is lower than a maximum gray of the first correction image data.Type: ApplicationFiled: January 5, 2016Publication date: May 12, 2016Inventors: Myoung-Chul KIM, Dong Keon KIM, Bo-Ram KIM, Tae Eun KIM, Seoung Bum PYOUN

Patent number: 8897474Abstract: Provided is a synchronization system and method for acoustic communication in audible frequency range, and an apparatus applied thereto. The synchronization system for acoustic communication in audible frequency range is configured to prevent deterioration of a synchronization performance and to reduce an amount of calculation by calculating a correlation based on a few samples as opposed to calculating a correlation for each sample when a receiver of the acoustic communication performs synchronization while the acoustic communication is performed in the audible frequency range through modification of an audio signal or adding of a predetermined signal to an audio signal.Type: GrantFiled: June 18, 2012Date of Patent: November 25, 2014Assignees: SK Telecom Co., Ltd., SNU R&DB FoundationInventors: Dong Keon Kim, Moon Kee Kim, Keun Hwan Choi, Jae Hwang Yu, Min Seok Kim, Nam Soo Kim, Hwan Sik Yun, Ki Ho Cho
