Brief Description: The investigation of glomerular disease prevalence is vital for comprehending chronic kidney disease development, particularly in regions like Kazakhstan and Central Asia, where confirming data is lacking. This study focuses on the epidemiology of glomerular diseases, utilizing registered cases of glomerular diseases in the national electronic health system. Research Methods: The research involves data from 31,421 patients recorded in the Unified National Electronic Healthcare System database, covering glomerular diseases with ICD-10 codes N01-N08 between 2014 and 2019. Descriptive statistics encompass demographic characteristics, all-cause mortality, prevalence and incidence rates, and comorbidities. Results: Results reveal a substantial rise in diagnosed cases from 7,756 (2014) to 30,686 (2019), with corresponding all-cause mortality increasing from 254 to 1,025. Also, new cases went up from 4,875 (2014) to 6,320 (2019). Over the period, 51% were women, 49% were men, and 67% were of Kazakh ethnicity. Russian nationality constituted 16%, and other ethnic groups comprised 17%. Diabetes mellitus emerged as the primary comorbidity, associated with 20% of cases. Conclusion: This is the first descriptive study in Central Asia scrutinizing the epidemiology of patients with glomerular diseases (ICD-10 code N01-N08) using administrative healthcare data in Kazakhstan. The findings indicate an escalation in prevalence and mortality, coupled with a gradual increase in incidence among glomerular disease patients from 2014 to 2019. The study underscores the pivotal role of diabetes mellitus as a predominant comorbidity in this context.

This article deals with installations with complex and nonstandard executive instrument movement. Having analyzed the technical implementation and operational features of cold-rolling pipe mills, the research team formulated the problem of synthesizing electric drives of auxiliary mechanisms. It is shown that the conditions for choosing a mechanical converter are associated with the oscillation of the processes of the electric drive system. The finite element method and the gradient descent method are used for structural analysis of solids and electromagnetic calculations. The data of the specific cost of semiconductor converters were analyzed using a linear least-squares regression technique. The advantages of a synchronous reluctance motor of independent excitation for the electric drives of auxiliary mechanisms are given and substantiated. The optimization of the geometrical parameters of the electromechanical converter was carried out according to the maximum developed electromagnetic torque. Modern semiconductor technology in the design of special-purpose electric drives leads to a revision of the principles for determining the optimal number of phases and the structure of the motor power supply. The rationale for the use of multilevel frequency converters is given. Taking into account an in-depth preliminary analysis and an integrated approach, these tasks were successfully completed, which was confirmed experimentally at the implementation of the developed system.
