These days, most of electric power facilities need high stability. Therefore integrated system has been required to monitor and control electronic power distribution system in fields at all times when the interruption of electric power has occurred. To construct this system, unit that convert and process the input signal from fields needed. And for control and monitoring from remote place MMI software is required. Lastly network equipments are required for real-time communications. So, in this paper, units for control and monitoring of emergency power generator and for electric power monitoring in normal electric power and interruption of electric power are developed. Also integrated remote system for monitoring in remote is developed.

This paper introduces an approach to the realization of an ICT-based bridge remote monitoring system that enables real-time monitoring and controlled adjustments for unexpected heavy loads and also for damaging earthquakes or typhoons. In this paper, an integrated bridge remote monitoring system called the "Intelligent Bridge", which consists of a stand-alone monitoring system (SMS) and a web-based Internet monitoring system(IMS), was developed for not only bridge maintenance but also as an application for a para-stressing bridge system. To verify the possibility of controlling the actual structural performance of an "Intelligent Bridge", a model 2-span continuous cable-stayed bridge with adjustable cables was constructed. The experimental results demonstrate that the implemented monitoring system supplies detailed and accurate information about bridge behaviour for further evaluation and diagnosis, and it also opens up prospects for future application of a web-based remote system to actually adjust in-service bridges under field conditions.

Remote Sensing Monitoring and Loss Estimated System of Flood Disaster based on GIS is an integrated system comprised flood disaster information receiving and collection, flood disaster simulation, and flood disaster estimation. When the system receives and collects remote sensing monitoring and conventional investigation information, the distributional features of flood disaster on space and time is obtained by means of image processing and information fusion. The economic loss of flood disaster can be classified into two pus: direct economic loss and indirect economic loss. The estimation of direct economic loss applies macroscopic economic analysis methods, i.e. applying Product (Industry and Agriculture Gross Product or Gross Domestic Product - GDP) or Unit Synthetic Economic Loss Index, direct economic loss can be estimated. Estimating indirect economic loss applies reduction coefficient methods with direct economic loss. The system can real-timely ascertains flood disaster and estimates flood Loss, so that the science basis fur decision-making of flood control and relieving disaster may be provided.

원격탐사 기술의 발전과 활용 가능한 위성의 증가로 재난의 예방, 대비, 대응, 복구 등에서 위성영상자료의 활용에 대한 요구가 높아지고 있다. 위성영상은 센서의 특성에 따라 적용 가능한 재난의 모니터링을 위해 활용되고 있지만, 통합된 모니터링 시스템의 구축을 위해 기존 시스템을 평가하고 이를 바탕으로 실현 가능한 준실시간 통합 재난모니터링 시스템 구축을 위한 구체적인 청사진을 제시한 연구는 국내뿐만 아니라 국외에서도 그 사례가 확인되지 않는다. 본 연구는 원격탐사를 통한 재난모니터링의 개념화를 통해 준실시간 재난모니터링 시스템 구축의 장애요인들을 확인하고, 실제로 활용 가능한 영상자료와 실현 가능한 재난모니터링 시스템을 제시하였다. 원격탐사를 통한 준실시간 재난모니터링은 다양한 요인들에 의해 통합시스템의 구축이 제한되며, 시스템 구축을 위한 기술적, 경제적 요인과 함께 위성영상 확보의 적시성을 가로막는 정책적 요인과 일관성 있는 정보생산을 위한 영상분석에 대한 제도적 요인에도 크게 영향을 받는 것으로 나타났다. 이러한 제약들은 AWS(Amazon Web Services)와 같은 위성영상의 저장, 취득, 분석에 활용되는 컴퓨팅 플랫폼과 같은 통합서버의 확보와, 재난의 종류와 상황에 부합하는 활용 가능 위성의 궤도분석을 가능하게 하는 분석도구의 개발에 의해 극복될 수 있을 것으로 판단된다. 본 연구는 이러한 제도적, 경제적, 기술적, 정책적 제약들을 극복할 수 있는 위성영상 기반 통합 재난모니터링 시스템 구축을 위한 프레임워크를 제시하였으며, 재난의 종류와 단계에 따른 AI 기반 위성영상 분석 방법론을 제안하였다. 이러한 결과는 원격탐사와 재난관리 분야에 학술적 시사점을 제공하고, 재난모니터링 분야에 실무적 기여를 할 것으로 판단된다.

Today, most of elevators have an emergency call facility for emergency situations. However, if the network installed in the elevator is also out of power, it cannot be used for the elevator remote monitoring and management. So, we develop an integrated and unified emergency call system, which can transmit not only telephone call but also data signals using PSTN(Public Switched Telephone Network) in order to remote monitoring and management of elevators, even though a power outage occurs. The proposed integrated emergency call system to process multiple data such as voice and operational information is a multi-channel board system which is composed of an emergency phone signal processing module and an operational information processing module in the control box of elevator. In addition, the RMS(remote management server) systems based on the Web consist of a dial-up server and a remote monitoring server where manages the elevator's operating information, status records, and operational faults received via the proposed integrated and unified emergency call system in real time. So even if there's a catastrophic emergency, the proposed RMS systems shall ensure and maintain the safety of passengers inside the elevator. Also, remote control of the elevator by this system should be more efficient and secure. In near future, all elevator emergency call system need to support multifunctional capabilities to transmit operational data as well as phone calls for the safety of passengers. In addition, for safer elevators, it is necessary to improve them more efficiently by combining them with high-tech technologies such as the Internet of Things and artificial intelligence.

14 Pressurized Water Reactors (PWR) in Korea use a remote monitoring system (RMS), which have been used in Korea since 1998. A Memorandum of Understanding on Remote Monitoring, based on Enhanced Cooperation on PWRs, was signed at the 10th Safeguards Review Meeting in October 2001 between the International Atomic Energy Agency (IAEA) and Ministry Of Science and Technology (MOST). Thereafter, all PWR power plants applied for remote monitoring systems. However, the existing method is high cost (involving expensive telephone costs). So, it was eventually applied to an Internet system for Remote Monitoring. According to the Internet-based Virtual Private Network (VPN) applied to Remote Monitoring, the Korea Atomic Energy Research Institute (KAERI) came to an agreement with the IAEA, using a Member State Support Program (MSSP). Phase I is a Lab test. Phase II is to apply it to a target power plant. Phase III is to apply it to all the power plants. This paper reports on the penetration testing of Phase I. Phase I involved both domestic testing and international testing. The target of the testing consisted of a Surveillance Digital Integrated System (SDIS) Server, IAEA Server and TCNC (Technology Center for Nuclear Control) Server. In each system, Virtual Private Network (VPN) system hardware was installed. The penetration of the three systems and the three VPNs was tested. The domestic test involved two hacking scenarios: hacking from the outside and hacking from the inside. The international test involved one scenario from the outside. The results of tests demonstrated that the VPN hardware provided a good defense against hacking. We verified that there was no invasion of the system (SDIS Server and VPN; TCNC Server and VPN; and IAEA Server and VPN) via penetration testing.
