ABSTRACT
The monograph, based on the analysis of statistical data, establishes the wave-like nature of changes in the demographic situation and its periodization in Ukraine. The dependence of the birth rate on changes in GDP is formalized. An assessment of the volume of the educational market and forecasting changes in the contingent of applicants for secondary and higher education are evaluated. A quantitative analysis of the labor market in terms of groups of specialties and educational programs, and a quantitative assessment of the compliance of the popularity of entrants in specialties and educational programs to the demands of the labor market are conducted. It is conducted a quantitative analysis of employers' requirements for candidates for a job, the availability of higher education and work experience. The demand of employers for soft skills job seekers and professional competencies in terms of specialty groups are estimated. The impact of the COVID-19 pandemic on the structure of the labor market is studied. The clustering of specialties and educational programs by the criterion of similarity of demand for personal and professional competencies is conducted. The achievements and shortcomings of the functioning of the system of external independent evaluation (EIE) of learning outcomes in Ukraine are formulated. The possibilities of using the psychological characteristics of entrants, the scores of their EIE certificates to assess future learning outcomes and to assess career prospects after graduation are researched. A quantitative analysis of the system of financing higher education in Ukraine, including the current system of distribution of budget funds between of higher education institutions is conducted. The shortcomings of the current system and ways to eliminate them are substantiated. © 2021 V. Ponomarenko.
ABSTRACT
In this paper, we compare four methods of extracting the sequence of intervals between heartbeats from the photoplethysmogram signal to estimate the total percentage of phase synchronization of autonomic regulation circuits of blood circulation that are designed to operate in real time. In the analysis of the experimental ensemble of records of healthy subjects, the optimal parameters for the used approaches were selected. We compared cardiointervalograms obtained from photoplethysmogram signals with cardiointervalograms isolated from simultaneously recorded electrocardiogram signals during the analysis of phase synchronization between the phases of the extracted signals in the low-frequency range (0.04–0.15 Hz), which reflects the element activity of autonomic control of blood circulation. The operability of the approaches used in the analysis of the total percentage of phase synchronization of the autonomic regulation circuits of the cardiovascular system based on the photoplethysmogram signal for groups of healthy people and patients during COVID-19 was demonstrated.
