Smart home and artificial intelligence technologies are developing rapidly, and various smart home systems associated with artificial intelligence (AI) improved the quality of living for people. In the present research, we examine the role of individuals' motivational system in their responses to the application of AI in smart homes. In particular, this research focuses on individuals' prevention motivational system and investigates whether individuals' attitudes toward the application of AI in smart homes differ according to their level of prevention motivation. Specifically, it is hypothesized that individuals with strong (vs. weak) prevention motivation will have more favorable attitudes toward the application of AI in smart homes. Consistent with the hypothesis, the results reveal that the respondents in the strong (vs. weak) prevention motivation reported significantly more favorable attitudes toward the six types of AI-based application in smart homes (e.g., AIbased AR/VR games, AI pet care system, AI robots, etc.). Our findings suggest that individuals' prevention motivational system may be an effective market segmentation tool in facilitating their positive responses to the application of AI in smart homes.

We present the motivation, design and implementation of a smart home system in Korea. Our system is open, extensible, integrated, intelligent, and usage-centric. We detail the challenges and key design requirements for the smart home system based on our past experiences, and show how convergence system design is a capable methodology for enabling an integrated and multi-faceted home management system that encompasses energy management, home appliance control, environment management, u-health, and living support functionalities under a single unified design. Using energy management as a specific case study, we demonstrate how convergence system design can encapsulate technology heterogeneity and hardware-software disparity without compromising simple yet powerful user interfaces.

Smart homes have become the state of the art in the reduction and monitoring of energy usage within a residential setting. Emerging threats such as climate change, global warming and volatility in energy prices have fuelled the interest in smart systems. Given that environmental sustainability has become a more significant factor for consumers, this research examines whether consumers' attitudes toward smart home services for efficient energy management differ according to their regulatory focus. Specifically, it is predicted that consumers will have more favorable attitudes toward smart home services for efficient energy management when they are promotion-focused (vs. prevention-focused). The results indicate that respondents with a promotion (vs. prevention) focus reported significantly more favorable attitudes toward smart home services for energy management (e.g., smart cooling/heating system, smart ventilation & air conditioning system, smart thermostats, smart plugs, and smart switches). We suggest that regulatory focus may be an effective marketing and segmentation tool in promoting smart home services for energy management and facilitating their receptiveness to the services.

This paper is intended to suggest some reference materials for future elderly housing design, especially smart home, in Korea, by reviewing the elements and applications of smart home concept for older adults in USA. Research method includes collecting materials by attending the regular SmartHome$^{(R)}$ part meeting, the navigation of related homepages, and the analysis of collected materials. Current researches in Korea look initial stage and show some general principles without practical concept & technologies of elderly facilities. SeniorSmart$^{(R)}$ Center in USA started on August 2007 with the 3 parts of SmartHOME$^{(R)}$, SmartWHEELS$^{(R)}$ and SmartBRAIN$^{(R)}$. The Center has been doing various multidisciplinary research projects but slowing down the planned processes due to national economic recession. The major researches of SmartHome$^{(R)}$ part can be summarized as follows; CS-PFP( Continuous Scale Physical Function Performance) laboratory is being in operation to help older adults and families make the difficult decision regarding the ability and safety to live independently. Three levels of necessary laboratories from uninhabited space to senior living environment were accommodated for field research. As core technologies of SmartHome$^{(R)}$, predicting & warning system of fall risk on recognizing gait signature patterns to identify any deviation from the normal patterns of the older adults, home monitoring system which will send alerts to a specified relative and/or health care professional when vital signs of the older adults will not be within normal parameters, and Mobility & Research Clinic for evaluating, treating the older adults & multidisciplinary research are under development. SmartHome$^{(R)}$ has made collaborative research agreements for field laboratory with various retirement communities and also is continuing to work for experimental software engineering with the Fraunhofer Institute, Germany.

Thanks to internet, as one of indispensable parts of our lives, many devices that we use in our daily lives like TV, air conditioner, refrigerator, washing machine, can be monitored and controlled remotely by becoming more intelligent via Internet of Things (IoT) technology. Smart Home applications as one of the elements of smart cities, are individually the most demanded application without question. In this study, Smart Energy Management (SEM) system, based on NodeMCU and Android, has been designed for SEM, which is a part of the smart home application. With this system, household energy consumption can be monitored in real time, as well as having the ability to record the data comprising of operation times and energy consumption information for each device. Additionally, it is ensured to meet the energy needs on a maximized level possible, during the hours when the energy costs are lower owing to the SEM system. The Android interface provides the users with the opportunity to monitor and change their electricity consumption habits in order to optimize the energy efficiency, along with the opportunity to draw up of a daily and weekly schedule.

Smart home systems for safety and security are in high demand and always needed for many reasons including people's desire to feel safe in their own houses and to avoid a high rate of crime. In the current research, we investigate the role of individuals' motivational orientation to prevention in their responses to smart home systems for safety and security. That is, this research examines whether individuals' attitudes toward smart home systems for safety and security vary depending on their level of prevention orientation. Specifically, it is hypothesized that individuals with strong (vs. weak) prevention orientation will have more positive attitudes toward smart home systems for safety and security. In support of the hypothesis, the results indicate that respondents in the strong (vs. weak) prevention orientation reported significantly more positive attitudes toward smart home systems for safety and security. Our findings imply that individuals' motivational orientation to prevention may be an effective marketing and segmentation tool in facilitating their favorable responses to the smart home systems for safety and security.

Recently, Smart Home System(SHS) is applied in order to provide comfort, energy efficient and better security to the residence. Thus, by introducing the SHS in the house of elderly people, it is possible to provide a convenient and safe life for old people especially living alone. This paper presents the design and implementation of a low cost but yet flexible and secure smart-phone based SHS. The design is based on inter-working between Arduino board with Bluetooth and Arduino board with Ethernet shield, and the home monitor/appliances are connected to the input/output ports of this board via sensors/relays. In addition, when the old man is put on an emergency, the proposed system will automatically notify it the family. Therefore, we have implemented an inexpensive and efficient SHS for the elderly living alone by inter-working smart phones, internet server and Arduino micro-controller.
