Abstract: The present application relates to a method of generating a downlink frame. The method of generating the downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by the first short sequence and a fourth scrambling sequence determined by the second short sequence; scrambling the short sequences with the respective scrambling sequences; and mapping the secondary synchronization signal that includes the first short sequence scrambled with the first scrambling sequence, the second short sequence scrambled with the second scrambling sequence and the third scrambling sequence, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled by the second scrambling sequence and the fourth scrambling sequence to a frequency domain.

Abstract: An attack tracking system includes multiple hosts in which first event data concerning object behavior are collected and pieces of host-based event information are created therefrom; a tracking information database server storing the pieces of host-based event information; a tracking information analysis server creating behavior events by defining malware behavior from the pieces of host-based event information, retrieving targets to be analyzed from the pieces of host-based event information and the behavior events based on a preset input value, creating first tracking contexts for identifying the malware behavior by analyzing the relationship between the pieces of host-based event information and the relationship between a set of the pieces of host-based event information and a set of the behavior events, and creating second tracking contexts tracking malware routes and behavior events between the multiple hosts by analyzing the correlation between the first tracking contexts.

Abstract: An organic light-emitting display apparatus including emitting pixels including drivers for displaying gradation by making a light-emitting device selectively emit light according to a logic level of a data signal transmitted to each of the sub-fields forming a frame, and dummy pixels coupled to a repair line that is coupled to a light-emitting device of a first emitting pixel from among the plurality of the emitting pixels, wherein the dummy pixels include a first dummy driver for making the light-emitting device of the first emitting pixel emit light by charging the repair line when a data signal having a first logic level is transmitted, a second dummy driver for discharging the repair line when a data signal having a second logic level opposite to the first logic level is transmitted, and a boost capacitor coupled to the repair line and for controlling a charging/discharging speed of the repair line.
