The elderly are an age group that experiences the aging process with various physical, mental and social changes that affect their quality of life. As the number of elderly people increases in various countries, it is important to have a clear understanding of the scope of the needs and conditions of the elderly from a social, health and economic perspective. The aim of this research is to determine the scope of the needs and conditions of the elderly. This research method uses a qualitative approach and involves literature study, data collection techniques using interview methods and literature research. This research discusses the health needs and conditions of the elderly, with a focus on medical aspects of care, including ongoing care and management of chronic conditions (such as diabetes, cholesterol and high blood pressure). Elderly people also experience several challenges, such as accessing health care facilities which is often difficult due to distance, physical limitations, or dependence on family for care. Therefore, researchers hope to provide a deeper understanding of the challenges and needs of the elderly, as well as families spending more time providing care.
 

In the context of rapidly evolving mobile technology, memory management has become an important aspect that determines the efficiency and effectiveness of Android operating systems, particularly on mid- range smartphones. The objective of this research is to identify, analyze and develop memory management strategies that can improve the performance of the Android operating system on resource-constrained devices. Using an experimental approach, this study evaluates various memory management techniques, including the use of optimized caches, memory compression, and page replacement algorithms, to determine the most effective combination to improve system responsiveness and performance. The results show that the implementation of appropriate memory management strategies can significantly improve operating system performance and user experience while extending battery life. These findings provide valuable information for application developers and device manufacturers to optimize their products for mid-range smartphone competition.
