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 ...

OBJECTIVE We aimed to analyze, from the data in a national survey, the use of oral care and the oral health status of patients living at home or in an institution. BACKGROUND Patients aged 60 years and older have important oral health needs, but their oral management may differ according to their immediate environment. The fact of living at home or in an institution can influence the use of c...

Broadband access service, including FTTH, is now in widespread use in Japan. More than half of the households that have broadband Internet access construct local area networks (home networks) in their homes. In addition, information appliances such as personal computers, networked audio, and visual devices and game machines are connected to home networks, and many novel service applications are...

This paper designs a portable smart home system which based on ARM embedded gateway and Zigbee wireless sensor network. With the low power consumption, ad-hoc network, scalability and high practicability of ZigBee technology, wireless sensor network is built in the home. The smart home system use S5PV210 processor as the core of Hardware platform and use embedded Linux operating system as real-...

Homes, offices and many other environments will be increasingly saturated with connected, computational appliances, forming the “Internet of Things” (IoT). At present, most of these devices rely on mechanical inputs, webpages, or smartphone apps for control. However, as IoT devices proliferate, these existing interaction methods will become increasingly cumbersome. Will future smart-home owners...

Cerebral palsy (CP) is one of the most severe childhood disabilities due to a lesion in the developing brain. Oral conditions often observed in this pathogenic are a tendency for the delayed eruption of permanent molars, higher percentages of malocclusion and parafunctional habits, including bruxism. The significance of oral conditions observed in CP patients demonstrates the need for intensive...

Appliance energy labels are gaining global recognition as policymakers increasingly prioritize measures to enhance efficiency and reduce carbon emissions. They serve effective tools in encouraging consumers choose appliances that more energy-efficient. This study investigated consumer preferences their willingness pay (WTP) for on rice cooker specifically. The data was surveyed through a choice...

In this paper, an Information Appliance Control Platform (IACP) is presented. In this platform, users monitor and control appliances through a network-connected mobile device at home, even on the Internet. This platform is effectively built by the technologies of agent, embedded system, networking, database and serial communication. Three subsystems developed in this platform are User Interface...

Non Intrusive Load Monitoring (NILM) is the method of obtaining information about appliance-level power consumption inside a building from voltage and/or current measurements made at a central location in the electrical system. The system that does this kind of power disaggregation typically relies on some sort of training step to help it recognize what types of changes in the observed signal c...

IoT service provides interconnection between ‘Things’ in many industry areas (home appliance, traffic, medical services, etc.). However, because of the IoT environment is consisted of various devices, network protocols, platforms, there are many security risks such as IoT device hacking, privacy infringement, information leakage, etc. Therefore, to make a secure and safe IoT environment, identi...
