[Global demographic problem and active aging (literature review)].

The article presents an overview of foreign sources devoted to the problems of population aging as a significant phenomenon that has become the most important medical and socio-demographic challenge in the world. The review provides global data on this problem and shows the need for elaborating and implementing active aging strategies, optimizing opportunities for health, participation and safety in order to improve the life quality as people age. The paper employs the method of content analysis of scientific publications retrieved in PubMed database by keywords - «aging¼, «population aging¼, «demographic trend¼, «longevity¼, and «life expectancy¼. Scientific publications for the period 2018-2023, WHO and UN materials, statistical data, and popular scientific publications have been studied. The purpose of the review was to analyze trends and global nature of aging based on scientific publications and open sources, and to highlight the most promising areas of the demographic policy on the older adults. In the time of rapid demographic changes, it is extremely important to use all available opportunities that maximize healthy aging with the participation of the older adults. We should remember that aging is a natural process and it is better to accept it, both psychologically and physically, rather than ignore. Healthy aging should become and has become the main principle of life, suggesting a longer healthy life of the older adults, who, in turn, should understand how to accept and implement this principle in their lives.

[DETERMINING THE LEVEL OF TECHNOLOGICAL READINESS OF DEVELOPMENTS IN MEDICINE BASED ON THE TRL METHODOLOGY].

The article discusses an approach to assessing the level of maturity of medical technologies based on the TRL (technology readiness level) methodology. The author presents a tool for planning scientific results and developments in the direction of «medical sciences¼ with a clear description of the expected results at each level of research and development. The levels of technological maturity of developments in the field of healthcare are described in detail, possible results and reporting forms for each level are presented, their differences are analyzed depending on the planned final product. Also presented are proposals for the distribution of powers between the state and business to finance the process of creating and implementing a new medical technology, depending on its stage of maturity.
