Torsional vibrations of a rotating viskoelastic rod
A homogeneous and isotropic round viscoelastic rod rotating around its axis of symmetry with a constant angular velocity is considered in a cylindrical coordinate system. It is believed that the behavior of the rod is described within the framework of the linear theory of viscoelasticity, where the relationship between stresses and deformations is given in the form of relations Boltzmann-Volterra. In this case, the condition of its reversibility is imposed on the kernel of the integral operator. The equations of motion of the rod concerning non-zero stress components are written, taking into account the centrifugal force caused by the rotation. It is assumed that torsional vibrations are caused by given stress on its surface. A general equation of torsional vibrations of such a rod is obtained, which is an integral-differential equation of infinitely high order for the main part of the torsional displacement. Limiting the general equations to the zero and first approximations, the equations of the second and fourth orders are obtained, which, in the case of the absence of rotation, exactly coincide with the known equations of other authors. The resulting refined equation of the fourth order in its structure considers the angular velocity of rotation, the deformation of the transverse shear, and the inertia of rotation. Based on the derived oscillation equations, a particular problem is solved to study the influence of rotation and viscoelastic properties of the material on the stress-strain state of the rod, according to the results of which graphs of the dependencies of elastic and viscoelastic changes on time at points of three different sections of the rod are constructed. A comparative analysis of the results obtained with the results of other authors is performed

MEDICAL EDUCATION: FEATURES OF THE COURSE SIMULATION EDUCATION
The research includes the study and analysis of the implementation of simulation training. The effectiveness of the integration of distance and simulation education. Creation of a center for simulation training and the work done in the process of teaching students. The objective of the study is to provide data on simulation education, on the features and problems of the implementation of simulation education and the main tasks assigned to teachers. Also, the purpose of the study is to determine the features of the organization of the theoretical content and methods of teaching influences of the online course Simulation Education . Material and methods. The research materials are based on the experience of creating and teaching the course (in the MOODLE system) Simulation Education at the Tashkent Medical Academy, on the results of research work related to finding ways to modernize modern higher medical education, as well as on a sociological survey of students. The object of the research was the undergraduate and graduate students of TMA. The study involved 192 students: 80 students studying in the specialty General Medicine , and 67 students of the medical and pedagogical faculty, 45 graduate students studying in various specialties. Conclusion. Thus, the experience of creating a course in simulation education indicates that the distance teaching format does not always contribute to the achievement of the set goals for the development of practical skills, the formation of competencies related to knowledge and skills in using modern international and legal documents, as well as principles, rules, approaches to solving urgent problems in the field of medicine
ALGORITHM OF COMPUTER PROGRAM FOR PERSONALIZED DYNAMIC OBSERVATION OF HYPERTENSIVE PATIENTS IN PRIMARY HEALTH CARE
Introduction. The present research covers data and analysis on implementation of the Algorithm of computer program for personalized dynamic observation of hypertensive patients in primary health care . In the health care system of Uzbekistan, as well as in the systems of other countries throughout the world, AH is a topical issue. Study objective: To increase the effectiveness of treatment and clinical observation of patients with hypertensive disease (HD) in primary health care settings. Material and methods: In the process of research data (for the past five years) of 222 randomly selected medical histories of patients with arterial hypertension, being under regular medical examination in family polyclinics (n=54) and in some rural health clinics of the Republic of Uzbekistan (n=168), was analyzed. Results of the analysis of the medical histories were compared with the results of examination of patients (questioning, medical examination, anthropometry, measurement of blood pressure, cholesterol test, etc.). Results and discussion: All the patients have been under the supervision for 2 years with subsequent repeated check-up and medical examination. In the core group (patients aged from 45 to 71 years, average age - 51.75 + 1.85 years; 29.5% males, 70.4% females), the patients were broken down by stages as follows: Stage I hypertensive disease - 45 (36, 8%) patients; Stage II hypertensive disease - 62 (50.8%) patients; Stage III hypertensive disease - 15 (12.2%) patients. Hypertensive crisis was observed in 40 (32.7%) patients. The experimental group consisted of 114 patients (80 (70.1%) females and 34 (29.8%) males, aged 44-75 years, average age - 52.6 ± 1.62 years), they were treated by the traditional method and did not participated in the training. In the core group, as opposed to the experimental group, there were positive changes in the lipid profile: the number of arterial hypertension patients with hypertriglyceridemia decreased from 19.6% to 11.4% (p \u3c0.001); the number of arterial hypertension patients hypercholesterolemia decreased from 56.5% to 27.0% (p \u3c0.001). Taking into account the peculiarities of the existing model of prophylactic medical observation and using the accumulated data of numerous evidence medicine-based scientific studies of recent years, we have improved (personalized) and implemented into the inpatient practice of PHC physicians the individual tactic to observe hypertensive patients. For this purpose, there was developed the algorithm of a computer program to identify and individual tactic for dynamic observation of hypertensive patients, adjusted to PHC settings. Conclusions: The organization of training at the school for hypertensive patients led to a significant increase in the number of hypertensive patients with constant self-monitoring of blood pressure. The algorithm of electronic program for personalized dynamic observation of hypertensive patients was created on the base of obtained results of anamnesis, anthropometry, and laboratory and instrumental tests. Implementation of the algorithm of electronic program creates the possibility of routine detection of abnormal changes in the health status of hypertensive patients in the early stages of their development and the reasons of inadequate disease control. This increases the effectiveness of HD prevention and treatment at the primary health care level
