Abstract: A hybrid catalyst composition containing a heterogeneous transition metal compound, a catalyst for olefin polymerization containing the heterogeneous transition metal compound, and a method for preparing an olefin-based polymer in which generation of a gel is suppressed using the catalyst are disclosed. The method for preparing an olefin-based polymer can provide an olefin-based polymer in which non-uniformity of the olefin-based polymer, and in particular, generation of a gel is suppressed.

Abstract: Disclosed is a method of operating a storage device which includes a storage controller and a non-volatile memory device. The method includes providing a first request indicating a word line sequential read operation of a target memory block of the non-volatile memory device, providing first word line read data corresponding to memory cells of a first word line of the target memory block based on the first request, providing second word line read data corresponding to memory cells of a second word line of the target memory block based on the first request, the second word line being adjacent to the first word line, calculating a first word line gap value based on the first word line read data and the second word line read data, and performing a first reliability operation of the target memory block based on the first word line gap value.

Abstract: The present invention relates to an animal model for oxidative stress research and use thereof, and more specifically, the present invention can utilize a mutant of RCAT having a regulatory function for an antioxidant stress regulator in Caenorhabditis elegans and a human cell line expressing RCAT as animal and human cell line models for oxidative stress research, using the mutant and the human cell line.

Abstract: An audio record management method includes linking an app dedicated for audio record management installed in a first device and a website dedicated for audio record management connected to a second device; displaying an audio file being recorded or being played back in the app on a file list on the website through linkage between the app and the website; and providing a memo creation screen for the audio file on the website in response to a selection of the audio file from the file list.

Abstract: The present disclosure relates to a power seat integrated control method. One embodiment of the present disclosure includes: a signal input step of receiving a power seat operation signal input that a user inputs through an interface of a vehicle; a determination step of determining an operating condition for operating a motor module that is built into the power seat and moves a specific area of the power seat; and an information transmission step of transmitting driving information for controlling the motor module in accordance with a type of the operation signal. The motor module includes a driving motor and a motor controller which controls the driving motor, and one LIN communication bus is provided between the integrated controller and each power seat. In the information transmission step, the integrated controller transmits the driving information to the motor controller through the LIN communication bus.

Abstract: Provided is a method, system, and non-transitory computer-readable record medium to record a conversation, between multiple users, in connection with a video communication service. An audio record management method includes creating an audio record by converting an audio of a video communication channel to a text; and providing the audio record to a user that participates in the video communication channel.
