As the number of elderly increased rapidly every year, many elderly still choose to stay independent despite of difficulties and challenges faced in their daily routine. Elderly has desperate needs for support for their living. Internet of Things helps to support and improve elderly's life in many ways to meet the needs and requirements. Home Automation Control (EHAC) is a research based system that support elderly with controlled automation solution that control and operates various home electrical appliances based on the measurement of heart pulse rate and environment temperature. This paper works on EHAC system to evaluate the performance of the system in elderly's daily routine. This paper presented experiments conducted with approach of IoT testing and discussion on analysis of the results.

In this paper, 1 examined role gratification and role strain of South Korean working mothers. The results show that South Korean working mothers experienced very similar level of role gratification and role strain as taking their multiple roles. The findings also show that the factors of caregiving demands, employment demands, caregiving resources, employment resources are not strongly related to role gratification and role strain. Among the 12 caregiving demand variables and employment demand variables, number of children, type of family, number of hours worked were significantly related to producing role gratification. Among the 12 caregiving demand variables, number of hours worked, number of husbands absence due to night work were significantly related to producing role strain. Among the 8 caregiving resources, participants satisfaction due to income contribution, look to make a purchase new electric home appliances were significantly related to produce role satisfaction.

The advent of Internet of Things(IoT) has increased the need for development of smart life based on Information and Communication Technology(ICT). By using IoT technology, we are able to control connected appliances using smart devices, such as smart phone. To support the smart life, there is a need to utilize emotion information for human behavior, based on both biorhythm and environment information. Research towards this goal suggests a smart lamp control system that has an effect on the human emotion. According to the PSI theory, the control system calculates the biorhythm with an algorithm that uses the human biorhythm, weather factors and walking amounts. The smart lamp works with the recommended color lights that can control the feelings and emotions of the user. Here, we will show the effect of physical and mental stability, health care, and accident prevention.

The purpose of this study is to explore the economic hardship experiences of low-income single-parent families by COVID-19 to find ways to improve after COVID-19. To this end, 10 single parents with children under the secondary school age were recruited through snowball sampling method and in-depth interviews with economic activities, income, expenditure, and economic life. As a result of the study, participants suffered from unemployment and the disappearance of extra income activities in the early stages of COVID-19, additional expenses incurred by children's food and increased utility bills. In addition, it was recognized that COVID-19 has come to be more difficult and unequal to single-parent families of low-income women. It was found that the temporary living difficulties were resolved with disaster support funds, and it was helpful in the short term by spending according to priorities such as overdue monthly rent, food expenses, children's academy expenses, and purchasing home appliances. However, it was recognized that disaster support funds were inappropriate for customized disaster support and long-term and selective support was necessary.

As the world becomes an aging society due to a decrease in the birth rate and an increase in life expectancy, a system for health management of the elderly population is needed. Among them, various studies on occupancy and activity types are being conducted for smart home care services for indoor health management. In this paper, we propose a random forest model that classifies activity type as well as occupancy status through indoor temperature and humidity, CO2, fine dust values and UWB radar positioning for smart home care service. The experiment measures indoor environment and occupant positioning data at 2-second intervals using three sensors that measure indoor temperature and humidity, CO2, and fine dust and two UWB radars. The measured data is divided into 80% training set data and 20% test set data after correcting outliers and missing values, and the random forest model is applied to evaluate the list of important variables, accuracy, sensitivity, and specificity.
