  • 전력 텔레매트릭스 시스템은 전력계통의 사고에 신속하게 대처하고 계통설비의 합리적인 유지보수 및 운영을 통해 계통의 신뢰도를 높이고자 고안된 시스템이다. 이 시스템의 상위 HMI 부분은 MMS, CMD, FEA 등으로 나뉘어져 있는데 그중 CMD(Condition Monitoring Diagnosis) 시스템은 전력설비의 상태를 감시하고 진단하여 설비 유지보수에 도움을 주는 부분으로서 MMS과의 데이터 공유를 통하여 전력설비를 더욱 합리적으로 유지보수 및 운영할 수 있도록 하여주는 시스템이다. 본 논문에서는 이러한 CMD 시스템을 이루고 있는 핵심 알고리즘에 관하여 논할 것이다. 또한 개발된 알고리즘이 실제로 전력텔레매트릭스 시스템의 CMD 시스템에 삽입되어 현장 센서 테이터가 어떻게 이동이 되는지 보여 줄 것이다.

  • Images of TV that crossed the reality & the virtual reality have been discussed for a long time, Then, With what feature can TV make messages of the reality & the virtual reality maintain to achieve such a target, and in which situation will the feature be exposed? One who answered first about these questions is a German critic, G$\ddot{u}$nter Anders. Anders called the reality confused with the reality and the confused world of the virtual reality Phantom, and thought human beings would live in the reproduced world created by media machine in the long run as a world that the Phantom created would be gloomy and confusing. The media, themselves, become images, and an image creates another image. Through this process, human beings became unaware of which image the reality was indeed. As TV often created these situations, we have been already seduced into the deep Phantom world before discussing right or wrong of the situation. Of course, the media reality & the reality can't be strictly distinguished. Because the means that help to form judgement of viewers is the media. The subject of practical judgement is the media reality not human beings.

  • As modern megalopolises become more complex and huge, convenience and safety of citizens are main components for a welfare state. In order to make safe society, telemetrics technology, which remotely measures the information of target system using electronic devices, is an essential component. In general, telemetrics technology consists of USN (ubiquitous sensor network) based on a wireless network, smart sensor, and SoC (system on chip). In the smart sensor technology, the following two problems should be overcome. Firstly, because it is very difficult for transducer manufacturers to develop smart sensors that support all the existing network protocols, the smart sensor must be independent of the type of networking protocols. Secondly, smart sensors should be modular so that a faulty sensor element can be replaced without replacing healthy communication element. To solve these problems, this paper investigates the feasibility of an IEEE 1451 based ZigBee smart sensor system. More specifically, a smart sensor for large network coverage has been developed using ZigBee for active telemetrics.

  • Nowaday, television is evolving in an irreversible direction of algorithmic media in accordance with intelligence on the $4^{th}$ Industrial Revolution. From the viewpoint of the $4^{th}$ Industrial Revolution, this article aims to discuss the new modes of television, their cultural impact, and the changes in the nature and value of television (media). With these aims, this article considers how the concept of algorithm can be defined in new domain of digital media and how this definition would be applied in the industry fields of media by examining the Netflix's content-based filtering system, known as Netflix Quantum Theory. This article also explains based on remediation theory, how these algorithmic media are following an evolutionary course. Using this explanation, we elucidate the concept of intelligence worked by the algorithm in terms of computability, and we present the criticism that the 'optimization society' produced by using the algorithmic culture of the $4^{th}$ Industrial Revolution era has two facets, efficiency and surveillance.
