Recently, as the proportion of the elderly population in Korea has increased rapidly, it has entered an aging society. As the scope of social activities of the elderly increases, the risk of safety accidents is also increasing. The traffic accident rate of elderly pedestrians is higher than ordinary people. Although various smart devices for the elderly are researched and developed, electronic components are often used. Electronic devices may not be able to be used if charging is not regularly. In this paper, a smart hat, a smart system for the elderly and the weak, was implemented using solar panels. The system uses solar energy to provide reliable use of smart devices. It is believed to be helpful not only for the elderly but also for the weak people by easy to wear the hat.

Recently, novel viral infections such as COVID-19 have spread and pose a serious public health problem. In particular, these diseases have a fatal effect on the elderly, threatening life and causing serious social and economic losses. Accordingly, applications such as telemedicine, healthcare, and disease prevention using the Internet of Things (IoT) and artificial intelligence (AI) have been introduced in many industries to improve disease detection, monitoring, and quarantine performance. However, since existing technologies are not applied quickly and comprehensively to the sudden emergence of infectious diseases, they have not been able to prevent large-scale infection and the nationwide spread of infectious diseases in society. Therefore, in this paper, we try to predict the spread of infection by collecting various infection information with regional limitations through a virus disease information collector and performing AI analysis and severity matching through an AI broker. Finally, through the Korea Centers for Disease Control and Prevention, danger alerts are issued to the elderly, messages are sent to block the spread, and information on evacuation from infected areas is quickly provided. A realistic elderly support system compares the location information of the elderly with the information of the infected area and provides an intuitive danger area (infected area) avoidance function with an augmented reality-based smartphone application. When the elderly visit an infected area is confirmed, quarantine management services are provided automatically. In the future, the proposed system can be used as a method of preventing a crushing accident due to sudden crowd concentration in advance by identifying the location-based user density.

In this study, the process of providing information necessary to remove physical barriers such as road slopes that obstruct the activities of the disabled is in progress. Through experiments, we implement a quantified road surface roughness index that enables the implementation of IoT-based systems necessary for the elderly and the disabled to safely move to their destination. As a preliminary study, a road surface measurement device using a gyroscope was devised. To check the roughness and flatness of the road surface, X, Y displacement, and acceleration displacement were measured using a gyroscope. By calculating the measured data, the roughness and flatness of the road surface were quantified from 0 to 100. We implemented an algorithm that divides this index into 4 stages, displays it on a map, and provides it to users. Finally, a system for the disabled and elderly electric wheelchair users to secure basic mobility was established.

4차 산업혁명의 기술이 발전함에 따라 세계는 눈부시게 발전하고 있다. 그러나 그와 동시에 어르신들의 치매로 인한 사회적 비용의 증가로 발생하는 문제점 또한 무시하지 못할 수준에 이르렀다. 이에 조기에 치매를 선별하여 예방하는 것이 중요시되었으며 다양한 연구기관에서는 빠르고 쉽게 치매의 전 단계인 경도인지장애를 선별하고자 여러 선별 검사지를 제작하여 경도인지장애 선별을 통한 치매를 예방하는 데 노력하는 중이다. 하지만 다양한 상황으로 각각의 효율성이 경도인지장애 선별에 대한 기대에 미치지 못하고 있다. 그리하여 본 연구는 기존에 개발된 경도인지장애 선별지 들을 비교 분석 및 코로나 상황에 적합하게 비대면 방식으로 경도인지장애 선별이 가능하도록 보다 효율적으로 개선하였으며 이를 IoT 기기에 접목하였다. 또한 IoT 기기는 어르신들의 경도인지장애 선별검사에 대한 부담감을 줄이고자 친근한 인형 형태로 개발하였으며 상호작용을 위한 기능 제작을 통하여 마음 돌봄 서비스를 구현하였다.

최근 실내에서 아동 및 치매노인의 실종사고가 빈번히 발생함에 따라 안전에 대한 관심이 높아지고 있다. 이에 아동 및 치매노인의 위치를 알 수 있도록 GPS를 활용한 제품들이 출시되고 있다. 하지만 GPS단말기는 실내에서 위치추적이 불가능하다는 단점이 있다. 따라서 본 논문에서는 실외뿐만 아니라 실내에서도 대상자의 위치를 실시간으로 파악할 수 있는 위치추적 시스템을 개발한다. 개발된 시스템을 이용하여 피보호자가 이동한 경로를 실시간으로 추적하는데 도움을 줄 수 있다.

Korea is rapidly becoming an aging society due to lower birth rate and longer life expectancy. As elderly diseases are of a serious concern, the number of patients with dementia has been increasing significantly. For now, it has become a nationwide problem, as dementia is difficult to manage and requires a lot of social costs. To solve this, an IoT device has been devised that efficiently screens Mild Cognitive Impairment(MCI), the early stage of dementia. To design and implement the device, the latest IoT technology is introduced, the optimized Korean Version of Hasegawa Dementia Scale Revised(K-HDS) is utilized, and convenient service scenario with user-friendly design is applied. As a result, the symptoms of MCI have been screened quickly with convenient operation, which lead to the healthier society by the prevention of dementia.

Bluetooth low energy (BLE) beacon is an actively push-to-broadcast electronic signal and can be used for object identification. This paper uses such beacon-based identification and Internet of Things (IoT) technologies for the elder health management service system to simplify the user interfaces and steps for preventive elder care. In the proposed system, an elder's family member, caregiver, or medical worker can conveniently and quickly record daily health management information. Besides, through the statistics and analysis of the data on the back end of the system, it is helpful for the elderly to refer to the data of daily care management and future management trends. Similarly, it is also an essential reference data for system maintenance and the new preventive health care services development.

The Socialist Republic of Vietnam has become one of the top ten nations with the highest aging rate. The proportion of their aging population increased from 7.2% to 10.95% from 1989 to 2017 and entered into the aging society six years earlier than what had been anticipated in 2011. The main issues in such a society are the problems associated with the elderly living by themselves and their solitary deaths. This study attempts to find a solution which would mitigate the burdens of aging or aged population who are living in a lonely and solitary living condition focusing on the system used for the purpose of managing or monitoring of their daily lives to prevent any undesirable outcomes including solitary deaths. The study also discusses the possibility of introducing the system into Vietnam.

As increasing the number of the elderly people, various IT-based home systems for the elderly are actively studied. However, while most systems for the elderly focus on systems detecting emergency cases, systems considering energy reduction in the elderly housing are rarely found. In fact, the systems for the elderly housing consumes rather more electric power for their functions. In this paper, a emergency monitoring system including the functions to reduce energy useage is studied and it is implemented. Though the system, we can achieve both of future-oriented functions for the aged and green society, which are emergency monitoring and energy reduction.

Our society is aging rapidly. In this super-aged society, the increase in healthcare costs are considered a national problem that undermines the sustainability of social security. Various services for healthcare for the elderly have been promoted to address this. However, most of them have focused on healthcare after the outbreak of chronic diseases and lack preventive healthcare. Most of the preventive healthcare projects are only pilots. In this paper, the current status of health care services for senior citizens at home and abroad was analyzed and based on this, the limitations and improvements were analyzed to propose the establishment of IoT-based Total Silver Care Center. IoT-based Total Silver Care Center may be conveniently monitored the health status of the elderly through various sensors, medical devices, and smart bands. And based on this, it can improve the quality of nursing services through time-saving and work efficiency of nursing providers. In addition, health care interventions may be provided in a timely manner if there is a change in the health status of users. And real-time imaging systems can help overcome mental difficulties.
