Children need oral care according to their developmental stage and accordingly, the appropriate dental treatment is different, which requires parents to have an active attitude and the applicable oral knowledge. As there is so much unreliable oral care information and PR, it is hard to find accurate information and parents are in need of a preventative oral healthcare mobile application for healthy oral care. Also, pediatric adolescent care should be focused on prevention rather than treatment and children should be instructed and educated to eat cariogenic foods as little as possible as well as told to brush before going to bed. This study designed a smart application for oral health care education to provide information and knowledge regarding oral health care for infants, oral health education, and oral health care prevention for parents of young children.

Although smart homes have been much developed in China, smart homes has been mainly towards the adoption of new technologies. There is little development of smart homes to consider and meet residents' needs in China. This study investigated residents' living in apartments in China using a questionnaire to identify their demands on smart homes. Through the survey, this study analyzed residents' space use patterns, daily living patterns etc. according to their ages. The results implied that there are significant differences in the use of spaces and demands on daily living within apartments. The results of this study should be considered for the development of smart homes in future. For example, it might be easier for people in the 20's to adopt Internet of Things (IoT) and environmental control systems compared to other age groups because most of them in the 20's use smart phones effectively without difficulties. In case of people in their 50's who stay home more times for taking a rest and eating meals compared to other age groups, smart technologies should be applied to support their health care and works in housings.

A smart home system improves the elderly's quality of life by monitoring and analyzing their movements and health conditions with better health-care and social support services. Therefore, there has been an effort to adopt a smart home system for the independently living elderly. However, to the best of our knowledge, no study has investigated the usability of a smart home system on actual independently living elderly housing in long-term settings. Thus, this study aims to demonstrate the usability of a smart home system on independently living elders in living lab conditions. The BLE smart band and the BLE receiver were chosen for the smart home system to monitor the movement of the participants in their homes as well as to monitor the heart rates, step counts, sleep index. Nine independent living elderly from the senior welfare center in Kimjae participated in this living lab demonstration experiment for ten months. This demonstration experiment confirmed the effectiveness of low-cost and easily adoptable IoT-based BLE sensor sets on independent living elders and discussed the troubles and limitations of the experiment. By grasping the pros and cons of IoT-based BLE sensor sets, this study seeks to improve the accessibility and usability of smart home systems for the elderly population in independent living arrangements.

China has already entered the aging society and is predicted to become a super-aged society in 2020. The recent studies identified that the elderly has more interest in 'Aging-in-Place' which emphasizes deinstitutionalization since welfare facilities such as care homes and silver towns have separated the elderly from their local communities where they used to live in. The aim of this research is to propose a promising way for smart housing services who support the elderly's living in their homes, China. This research is to investigate the elderly's life and to identify their demands on housings for implementing such smart services. The elderly's living in apartments in Luoyang city, China, were investigated through interviews using a questionnaire survey. The results show that smart housing services should be provided to support the elderly's health, safety, leisure activities, comfortable living, and social relationships sustainably. In addition, such smart housing services should be intuitive since the elderly need to use easily smart services for their autonomous life in their homes. The smart housing services should be developed in the direction of enhancing the elderly's healthy and desirable life, and lessening their discomforts due to aging.
