추운 겨울 퇴근 길에 자동차 안에서 간단히 보일러를 가동시키고 냉장고에 접속해 어떤 음식이 떨어졌는지 확인해 집 근처 쇼핑몰에 들르는 세상, 먼 미래의 이야기가 아닌 우리 눈 앞에 다가온 스마트 홈 시대의 우리 일상이다. '스마트 홈'은 현실과 거리가 먼 이야기 같지만 오는 2007년까지 전체 가구의 60%인 1000만 가구에 홈 네트워크가 보급되고 차세대 광대역통합망(BcN) 구축이 완료되면 '인터넷'만큼 우리에게 친근한 일상으로 자리 잡을 것이다. 2007년 어느 주부의 일상을 통해 홈네트워크가 변화시킨 스마트 홈 세상을 잠시 엿보자.

In South Korea, it has been increased the necessity of supplying housing services to meet the needs and desires of various residents by reflecting various demographic and social changes. In particular, various smart device has been widely utilized in South Korea and the smart technologies, such as artificial intelligence and the Internet of Things has been developed rapidly. These smart technologies could support smart housing that allows residents to easily and comfortably employ residential services. However, it is necessary to improve the awareness of users in order to spread the smart housing residential services connected to smart technologies. For this reason, this study observed changes in users' perceptions of smart housing residential service technology using Living Lab. As a result, after experiencing the Living Lab, users' awareness of smart housing housing service increased, and it was observed that the preferred housing service technology was more detailed than before the Living Lab experience. This study shows that it is important to raise users' awareness for the dissemination of smart housing residential service technology, and that Living Lab can be an effective means for this purpose.

전력계통해석 중 전력조류계산과 안정도 해석에서 부하모델이 필요하다. 부하모델을 만드는 방법 중 미시적 방법에 의한 부하모델 방법은 몇 개의 부하군으로 분류하고, 전압, 주파수 변화에 따른 특성 실험에 의해 부하군의 개별부하 모델을 구축하고 각 부하군이 시간별 구성 비율을 이용하면 합성된 부하모델을 얻을 수 있다. 이 ��, 부하구성비 추정이 필요로 하게 된다. 본 논문에서는 스마트그리드 환경에서 구성될 새로운 주택모습과 그 안에 구성될 부하기기를 추론하고, 10년전에 이루어 졌던 부하모델 방법의 부하구성비와 스마트 그리스환경에서 구성될 새로운 주택의 부하구성비를 비교함으로써 부하모델을 10년 주기로 새로 예측해야 할 이유에 대해 서술하도록 한다.

Today we have an obligation to pass the beautiful earth and enrich people's lives to next generations. According to the keynote, governments have a lot of resources to support the smart grid policies. Also the demand of the implementation of smart home applied the concept of smart grid is increasing rapidly. But the construction of smart home is centered on a new public housing except the pre-existing house which is counted for most of more than 90% of total. In this study, we suggest the implementation solution to make smart-homelike for the pre-existing houses without additional wiring or construction. We develop the technology reducing the unnecessary standby power 800mW to 20mW drastically. If we apply this technology, by the power off of main IC the actual power depends on the consumption of minimal devise located on the AC input side. Then the standby power becomes approximately 20mW(110ac).

Recently, apartment housing tends to increase 3-4% every year by economic growth and development of construction technology in domestic construction industry. According to this tendency, construction enterprises are providing high-quality and various residential space, and residents also want high-quality apartment housing without any defect. Construction company make efforts to decrease construction defects in order to satisfy all the residents, and to improve company value. However, it is impossible to have no defect in construction because construction works are combination of many different complicated process. Because of the responsibility for the defect, conflicts between construction company and residents have been occurred. This study suggests defects management method that can be used from defect register phase to defect repair phase with a function of smart-device of the high penetration rate. The effectiveness use of the suggested method might save defects maintenance time and improve resident satisfaction about construction quality.

This study investigates the demand management and energy saving plan of the apartment house based on the ESS (: Energy Storage System), which is the main equipment in the field of electric power energy efficiency, and suggests standardization for various technical factors and operation. It contributes to the spread of ESS industry. In addition, to create ESS market for apartment houses and smart homes, housing IoT technology is used to integrate apartment houses with smart home-based ESS and it is possible to achieve use efficiency and economic feasibility of power users, We will study a business model that can reconsider the acceptability of power users.

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.

Modular construction is popular as a smart building system because it can shorten the construction period. This study proposed a precast concrete (PC) core system that can further shorten modular construction time. The system was developed and its structural performance was verified through computational analysis. The proposed PC core system is a complete PC construction method using dry bonding. The results of the study indicated that the proposed PC core system has structural stability and performance suitable for modular housing.
