The purpose of the study was to clarify the views of the authors on the substantive features of the selection of educational materials in the context of prioritizing their presentation in lecture presentations, to highlight key topics for discussion at seminar classes, and to outline practical tasks for creating pedagogical conditions for the formation of students' competent abilities to use the acquired knowledge in their own life and professional activity. The paper provides a theoretical analysis of the meaningful characteristics of the terms and concepts of the discipline, presents a vision of logical connections between them and the relevance of students' awareness of such dependencies. The results of empirical studies of students' conscious understanding of the essence of concepts are considered, and the authors' vision of the cause- and-effect relationships of false awareness and motivational attitudes to motor activity is illuminated. The novelty of the study should be considered the forms and methods proposed by the authors of introducing educational elements of theoretical familiarization into methodically grounded practical studies of one's own indicators of physical development and the dynamics of functional states in the conditions of extremity of the military state and distance learning. The conclusions point to the understanding of the contents defined by the topic, emphasize the views on the main directions of the selection of educational materials, the development of tools and methods of systematic training of students of the pedagogical profession for the assimilation of knowledge from the educational discipline "Culture of personal health" (in the part of the "Motion Technologies" Program). The authors classified the thematic areas into three groups: General theoretical (definition of terms and concepts and clarification of historical stages of development of the field of Physical Culture); Mastering knowledge about the peculiarities of health training and the basics of self-control; Mastering knowledge of methodological features of the organization of motor activity of schoolchildren.

CT scans vary from manufacturer to manufacturer. There are several generations of CT. The concept of CT generation is not so much related to the time of its birth, but to the use in the scanner of the type of motion of the emitter-detector system. The generation number (first, second, third, fourth, etc.) is related to the type of tube-detector system design. Three types of scanners are now available: third, fourth and fifth generation. The life of the first generation of CT was fleeting: the duration of the scan did not suit – about 20 minutes. and the computer reconstruction of the image took too long. Only the brain could be examined on such devices. As for the human body, the image turned out blurry, blurred. But the process of improvement continues. Today, research is being conducted on fourth- and fifth-generation devices. They have not one, but many X-ray emitters, up to 200. It uses a very powerful processor with high-speed information processing – up to 10 million operations per second. As a result, the scan time was reduced to 40-50 milliseconds. It is now possible (here is a scientific idea!) To see on the telemonitor the reduction of certain transverse layers of the heart 1-2 millimeters thick. At spiral CT in the course of research with simultaneous constant rotation of system “tube – detectors” the table constantly moves and thus there is a spiral movement of a fan-shaped beam through a patient’s body. Spiral CT makes it possible to examine the anatomical region in one period of respiratory arrest, and the thickness of the reconstructed layer is not related to the original width of the tomogram. Obtaining thin conjunctival sections, which are tightly arranged in a spiral, allows you to get three-dimensional reconstructions. In combination with intravenous bolus contrast and subtraction data processing, CT angiograms can be obtained, which reproduce images of large vessels. In recent years, multispiral (multislice) CT has been used, which is based on the principles of imaging as in spiral CT, but due to multi-row detectors for full rotation of the system “tube detectors” can display more than one slice (currently from 2 to 16 images). This has made it possible to perform studies of the heart, study a large anatomical area, such as the lungs, thin sections in one breath hold, and significantly improve the quality of multiplanar and three-dimensional reconstructions. In electron beam tomography, the source of X-rays is a large electron gun with several massive parallel anode targets located in semiconductor rings around the patient. The intense anode beam is directed along the tungsten anode rings. The electron beam thus obtained passes through the patient’s body and is received by a fixed array of detectors. This achieves a high tomography rate, which is sufficient for the study of a moving heart: clearly delineated images can be obtained without the use of synchronization with the ECG. With the help of electron-beam tomography it is also possible to perform CT angiography and construction of high-quality three-dimensional reconstructions. Thus, modern medicine is impossible without CT. For example, in neurology, computed tomography, in addition to skull bones, well identifies the ventricles of the brain, venous sinuses, subarachnoid cisterns, interhemispheric fissure, cortex, basal nodes, inner capsule, trunk, cerebellum and other structures. The radiation load does not exceed the level usual for X-ray examination. At the same time, CT scans provide 100 times more information about the brain than conventional skull x-rays. But its importance is not limited to use only for the diagnosis of various diseases. Under the control of CT perform punctures and directed biopsy of various organs and pathological foci. The role of CT in the control of conservative and surgical treatment of patients is extremely important. CT is a valuable method of accurate localization of tumors and directing the radiation source to the focus when planning radiation treatment of malignant tumors.

Goal. It consists in substantiating the rational design of the vibroconveyor as a component of the vibroconveyor line of length , which will provide the necessary technological parameters for the transportation of artificial cargoes. The difficulty of this task is that the speed of transporting goods by mass should be at least . Topicality. The need for these studies is due to the fact that the vibration machine interacts with the parameters of the oscillation system, the main of which are inertial, rigid and power. If they are correctly calculated and implemented in the design of a vibration machine, it will be robust. Failure to consider one type of parameters causes an error in the calculation. Method. The refinement of analytical expressions is carried out using the classical approaches for linear vibrational systems with harmonic perturbation. For this the physical model of the two-mass resonance oscillation system is considered and its mathematical model is developed as a system of linear differential equations. On the basis of this the solution is formed (the values of the amplitudes of oscillations). Unknown parameters remain rigid, provided that the inertia is constructed. Therefore, using the determinants of the matrix of coefficients for unknowns, the necessary mathematical operations are performed that satisfy the imposed conditions for the establishment of rigid parameters. Results. In the paper a series of analytical expressions are obtained that examine the mutual influence of rigid parameters in the system. A comparison of the obtained results according to the specified expressions with classical analytical expressions is made. It is established that the values according to the proposed expressions do not differ significantly from the classical approaches, and therefore, in the case of in-energy calculations, it is sufficient to use existing expressions. The proposed expressions are more precise and therefore recommended for scientific research. Scientific novelty. For the first time, we succeeded in synthesizing analytical expressions for the establishment of inertia-rigid parameters that allow more accurate calculation of two-mass resonance oscillation systems. It is established that for the correct choice of resonant alignments in the system, the mutual influence of rigid parameters in the system is not significant, and therefore it is scientifically grounded to use classical approaches. Practical significance. Established analytical expressions can be widely used in the design of vibration process equipment. The transparency of the output and the relative simplicity of the proposed analytical expressions allows for their widespread use in practice.

The European Green Deal is the latest climate and environmental protection program launched by the EU. This is a strategy to transform the EU into a resource-efficient economy, in which in 2050 there will be zero greenhouse gas emissions and economic growth will be decoupled from the use of natural resources. After approving the National Economic Strategy for the period until 2030, Ukraine joins and focuses on the European Green Deal and aims to achieve climate neutrality in 2060 (Natsionalna ekonomichna stratehiia, 2021). Such ambitious goals can become a huge challenge for our country, in particular, in environmental projects of recycling in construction. Popularization of the principles of the circular economy and the introduction of the best European experience in the reuse of industrial waste is not only a requirement for the successful accession of Ukraine to the EU, but also a prerequisite for the effective implementation of infrastructure projects, especially the post-war reconstruction of the country.
