이미지 영역 복제 (IRD)는 이미지 세그먼트를 복사하여 동일한 이미지에 붙여 넣어 생성됩니다. 영상에서 일부 요소를 숨기거나 강조하면 독자에게 잘못된 정보를 제공 할 수도 있지만 복사/이동/위조 탐지의 응용기술로 사용될 수도 있습니다. SIFT 및 SURF 기반 IRD 탐지 방법과 같은 일부 IRD 방법은 강력하고 성능이 매우 우수하지만 계산 속도가 매우 느리고 계산이 복잡합니다. 예를 들어, 이진 설명자(Binary Descriptor)를 기반으로 디자인 된 일부 모델은 매우 빠르며 메모리 사용량이 적습니다. 그럼에도 불구하고 감지 성능이 떨어집니다. 본 논문에서는 MPLBP (Multi-patch Local Binary Patterns)기반의 이미지 영역 복제 감지 방법을 소개합니다. MPLBP는 여러 패치 쌍을비교하여 식별 기능을 계산하는 이진 설명자 추출 기법의 확장기술입니다. 제안 된 방법은 각 그룹의 장점을 고려하여 위에서 언급 한 두개의 위조 탐지 그룹 간의 성능 격차를 최소화하기 위한 것입니다. 이 제안은 기존 IRD 감지 방법에 강력하고 히스토그램 기반 IRD 방법보다 훨씬 빠르다는 것을 보여줍니다.

In this paper describes a system that can monitor the energy usage of multiple loads through wireless communication in a low voltage distribution panel. These are basic data that can increase the efficiency of energy use of buildings and factories. However, the method using wired communication is expensive to construct and maintain. Instead of such wired communication, wireless communication is easy to install and expand can be an alternative. In this system, a measuring system is installed at each lower part of the distribution panel to measure the energy and a monitoring system capable of collecting and transmitting the measured values by wireless communication is constructed.

As power consumption has increased in recent years, switches have been developed to utilize systems for demand response (DR) that control supply by analyzing power demand predicted and predicted power demand through power monitoring. Existing switches can be controlled only when they are in the field by manually controlling them, but with developed switches, they can be controlled manually and remotely. The developed switch uses firmware based on the MQTT protocol to connect to and remotely control Ethernet over wireless communications such as WiFi. With its own monitoring program, switches can be controlled and maintained through real-time power monitoring.

More recently, HVDC's application to the power sector has been increasing. But clear maintenance standards have not been established. In addition, ICT facilities for HVDC-class converters need to be studied. In this paper, the availability of all stations considering the ICT facilities of BTB HVDC was evaluated. ICT facilities have a lower impact on availability than other subsystem facilities. In addition, the effects of each subsystem failure on the overall system and on the location of ICT equipment need to be studied.

Traditionally, the reliability of the power distribution system is calculated by considering the failure rate of the section and the outage duration time based on the switch that separates the load section. The on/off operation of the protection facility can be considered in a more advanced manner, but it is generally assumed that the operation of the protection facility is perfect.The power distribution system switch is an opening and shutting facility that does not shut down the fault current and operates after the protection facility operates. Therefore, on/off control through communication after protective equipment operation is important.In this paper, discuss the reliability calculation of the distribution system considering the failure of communication in the power distribution system.

Accordeing to the enforcement of the EU GDPR, General Data Protection Regulation, It is required to check the consent of the personal information items being kept, the acquisition procedure, the guarantee of the rights of information entities, and the measures to be taken in case of leakage. Furthermore, it is important to improve internal procedures to meet GDPR requirements. This study used DBSAT (Database Security Assessment Tool) to collect configuration information of database type of B shopping mall and check the current security status at A 's B shopping mall based on Oracle DATABASE. Based on this, we have created a report that can identify the GDPR compliance process by extracting identified risks and providing the recommendations. In the present study, we prepared confrontation and countermeasures to comply with the GDPR by changing the state that can be processed immediately.

As a core service of 5G, strategies are needed for more specific access through analysis of augmented reality services and technologies. AR is associated with a number of technologies(Display, Tracking, Graphic Rendering, Interaction, Contents, HW(3D/360 camera, Smart Device(SmartPhone, Smart Glass, HMD), IMU Sensor, Battery, Processor etc). In order to provide advanced AR services, trends in related technologies should be analyzed and applied according to the technology level.

In this paper, we introduce the communication system available in shielding environment using surface-wave. Surface-wave communication system is possible using special antennas. The antennas also attenuate radiation waves but strengthen surface-waves. In experiment results, this communication system can work at 14m distance

Siheung-si, Korea is nowadays facing severe threats, such as air pollution and rapid aging. As the solution to such problems, autonomous driving electric bus platform, and artificial intelligence health care based on citizen body data are being considered. In this paper, we introduce the two linving labs in order to solve the problems Siheung-si is faced. And also analyze the adequacy of deploying each living lab in Siheung-si in various perspectives.
