In this paper, a digital home electric overload alarm system based on DSP for smart home automation which can minimize electrical fire damage caused by an home electrical overload was made experimentally. To verify the validity of the home electrical overload alarm technology, an electric overload alarm performance evaluation system which can artificially generate the electrical overloads was designed, developed, and constructed, and the effectiveness of the overload alarm developed by the overload test was verified. In particular, an overload test EMTP model based on EMTP-RV was developed, and simulation and measurement results obtained from the overload test were compared, and the reliability of overload performance verification results was confirmed.

최근, 국내에서는 스마트홈 기술이 공동주택인 아파트를 중심으로 점차 도입되고 있는 실정이다. 스마트홈의 주거공간은 홈네트워크를 기반으로 하는 다양한 정보(가전)기기들이 활용되고 있다. 이러한 주거생활환경에 의해 전기에너지의 의존도가 지속적으로 증가하고 있어, 먼저 스마트 홈 환경하 수용가 변압기 2차측에서의 전기합선과 누전에 대한 전기안전 및 진단의 기반기술을 제시한다. 다음으로, 주거시스템이 지능형홈으로 발전함으로서, 소비 전기량이 급속히 증가하는 추세이다. 따라서 본 논문에서는 홈거주자의 정보가 전기기 사용유무에 따라서 전원상태를 지능적으로 차단/통전시켜 소비전력을 최소화할 수 있는 Auto 스위치에 대해 기술하고자 한다.

With the recent rise in nuclear families and single-member families, there is a need for the kind of home management unaffected by neither space nor time. Moreover, electronic devices in and around the home need to be managed efficiently and prevented from overheating, and there is an increasing risk of fire, theft, and leak of personal data with these devices, which is leading to an increase in the economic costs. Accordingly, there is a growing need for an efficient and secure smart home management system. This paper proposes a home management system that uses smart devices. This system has addressed the shortcomings of a conventional Internet-based home network. Furthermore, it communicates with IoT-enabled devices and features intelligent information home appliances that are isolated from personally identifiable information and which are secure against advanced persistent threats, a type of cyber-attack.

In 21 century, it is difficult to define the limit of home automation, Recently, based on the advanced digital communication technology and necessity, The scope of the home automation has widened to home energy management, integrated reading of home and home health care etc. beyond the existing home automation. However, those methodologies reduce the efficiency and economy, and make it harder to realize a compact home automation because those methodologies are proposed independently without a unified standard. Therefore, this paper investigates and analyzes these methodologies, and then proposes an advanced home automation system that enables a compact design and improves the efficiency and economics of the home automation system based on the analyzed result.

The purpose of this study is to provide implications for the demonstration and the spread of smart cities. For this, the European Lighthouse project, a well-known smart city initiative, is analyzed. This article investigates agendas, applied solutions, stakeholders and cooperation, and expansion strategies in the 18 Lighthouse projects implemented by the EIP-SCC Smart City Demonstration Project. Four implications are discussed for Korean smart city projects. First, in promoting smart cities, clear philosophies and principles should be established in response to global issues such as climate change. Second, smart cities should be understood as the approaches for problem-solving rather than simply applying advanced technology. Third, a business system should be established in a way to meet the needs of the actors participating in the smart city demonstration project. Finally, an evaluation framework should be established to verify the performance of the project. High-performing best-practice projects should be supported by articulating their standards for their lessons to be spread into other cities. The implications presented here can contribute to developing smart city models along with follow-up studies.

The National Housing Bond Information Relay System is a representative financial information relay system in which institutions are connected with center system. A centralized structure is expensive to construct and operate center, and there is a problem that all networks are disconnected when a failure occurs in the center system. In this paper, we propose the national housing bond information relay system model based on Blockchain technology that can process information safely and efficiently. The proposed model constructs a Blockchain network so that each institution that processes the national housing bond information can transmit information safely, and each institution manages the same distributed ledge by a smart contract. The proposed model can reduce the cost because it can process complicated national housing bond transaction information without a relay center, and a network usage and disk usage decreased by 1.7% and 8.53%.
