Data collection was carried out by a questionnaire method using a direct survey of respondents. Anthropometry was performed with the subsequent calculation of the body mass index (BMI) of the respondents. The assessment of the quality of life was carried out using the SF-36 questionnaire on indicators of physical and mental components of health, general health, vital activity and mental health.   Results. The respondents were divided into 4 groups: 1 – boys studying at a university, 2 – girls studying at a university, 3 – boys studying at a college and 4 – girls studying at a college. It was found that the surveyed girls have a lower self-assessment of health, more than 30 % of university and college students rate their health as mediocre and poor, and among young men this indicator was 25,0 % and 20,0 %, respectively. The physical component of health differed slightly in the groups. The psychological component of health in girls was: 32,98 ± 1.35 (in high school) and 38,98 ± 1,14 (in college) versus 41,10 ± 2,22 for boys in high school and 44,61 ± 2,12 in college. The indicator of the general state of health was 66,50 ± 4,01; 58,12 ± 2,86; 65,40 ± 4,48 and 63,85 ± 1,95 in representatives of the analyzed groups, respectively; mental health – 63,38 ± 3,83; 49,09 ± 2,63; 64,6 ± 4,48 and 60,34 ± 2,21.   Conclusion. Analysis of the data obtained indicates that there are gender differences in self-assessment of health, represented by lower indicators in girls. Moreover, students at the university show this more clearly, which requires more in-depth study. It has been established that first-year students of KSMU have motivation to lead a healthy lifestyle and promote it among the population, and it can be traced more clearly among students of the university.","PeriodicalId":166124,"journal":{"name":"Proceedings of the Southwest State University.

The article considers mathematical methods of primary analysis of auscultative data. Recordings of normal and hard breathing were used for the experiment. Frequency, time-frequency and autocorrelation analysis of respiratory sounds was performed.   Methods. The research was based on the theory of digital signal processing. The study uses auscultative data obtained from an experimental sample of an electronic auscultation system. Electronic records of hard (pathological) and normal human breathing over the left middle lung were used. Respiratory noises were converted into digital form with the following parameters: sampling frequency fd = 48 kHz; bit depth n = 24 bits; number of channels 1. To analyze the frequency information content of the recordings, their spectra were constructed. A fast Fourier transform was used to calculate the values in the spectra.  Results. In the presented work, the frequency characteristics of recordings of hard and normal breathing are analyzed. The values of autocorrelation functions are obtained. An author-regression model of the process of normal breathing is obtained. The problem of analytical determination of the model order remains open and requires a separate solution. The resulting model allows you to generate an equivalent breathing noise of inhalation or exhalation when a signal with a uniform is applied to its input.   Conclusion. A sample of the electronic auscultation system has been tested, methods of simplified primary analysis of auscultative data have been proposed. The difference in the results of the treatment of hard and normal breathing has no statistical significance due to the small sample.","PeriodicalId":166124,"journal":{"name":"Proceedings of the Southwest State University.

When choosing performance indicators, the following basic requirements should be taken into account: the indicator should have a quantitative expression and be calculated simply enough; the indicator should be selected taking into account the specifics of the task being solved and reflect the main characteristics of the phenomenon being evaluated; theindicator should be representative and ensure comparability of the evaluation results by the degree of preference, i. e. to prevent incomparable (indifferent) decisions.   Results. A method for evaluating the effectiveness of monitoring the technical condition of a complex technical object is presented, taking into account an additional expanded information description with qualitative features (expert assessments).   Conclusion. The effectiveness of the control directly depends on the accuracy and completeness of the control. The accuracy of existing control systems is quite high, but the completeness of control does not always take into account qualitative (expert) assessments about the object of control. Improving the efficiency of control systems should go not only at the expense of accuracy and speed, but also at the expense of completeness of control. As a criterion for evaluating the effectiveness of the control system, an assessment of the probability of a functional state of a controlled complex technical object is proposed.

Special attention during respiratory rehabilitation is paid to the type of human breathing, as well as automated methods for analyzing breathing. At the moment, the problem arises that most of the developed methods for analyzing breathing do not work with types of breathing: they either determine only one type, for example, diaphragmatic, or simply analyze the condition of the lungs. In this regard, there is a need to develop a method for analyzing and determining directly the types of human respiration. This article discusses three methods for solving the problem of determining the type of human breathing using a motion capture system and machine learning. The first method is based on static characteristics, for which the Random Forest model was used. The second method, which is based on time characteristics, used the Catch22 model. The third method, which determines the type of respiration using the characteristics of the sinusoid, used a composite model based on two models of Hist Gradient Boosting.   Results. Three methods have been developed to determine the type of human breathing. Machine learning models were trained for each of the methods to find the best accuracy result.

The methods of multicriteria analysis, parametric and structural synthesis were used. The principles of transmitting video information from unmanned aerial vehicles used to monitor emergency situations are analyzed. A critical assessment of the maximum transmission range of video information from unmanned aerial vehicles during emergency monitoring has been made.   Results. Graphs of the dependence of the energy reserve in the radio communication line between the unmanned aerial vehicle and the ground control system have been obtained, allowing to estimate the maximum values of the transmission range of video information of various quality in the 2.4 and 5.8 GHz bands when monitoring emergencies. The maximum line-of-sight range between the UAV and the UAV slightly depends on the lifting height of the antenna of the mobile UAV and at the lifting height of the UAV from 100 to 500 m is from 40 to 85 km.
