Introduction. Unfavorable tendencies in the health of the working population, especially those with high neuro-emotional stress in professional activities, the scarcity of information about the impact of professional factors on the health and performance of police officers, which is characterized by nervous and hard work, determine the relevance of this study.The aim of the study is to study the biological age with an assessment of the rate of aging of individual body systems and the level of somatic health of police officers.Materials and methods. We examined 110 men — police officers. Biological age was determined by an automated expert system of diagnostics of aging by the method of A.A. Podkolzin, V.N. Crutko. To quantify the level of somatic health the method of G.L. Apanasenko was used. We used clinical, physiological and computational methods to study the state of the cardiovascular and respiratory systems, static balancing, interviewing methods and mathematical statistics.Results. The accelerated rate of aging was revealed in 65.4% of the examined patients. Accelerated aging of the neuropsychic, respiratory and cardiovascular systems was the most common (97.3%, 94.6% and 75.5%, respectively). A decrease in functional activity of blood circulation was revealed in 70.9%. The coefficients of endurance of cardiac activity and efficiency of blood circulation exceeded the norm, which indicates a possible weakening of the activity and the state of fatigue of the cardiovascular system, myocardial weakness. The ratio of pulse wave velocity in the vessels of muscular and elastic types below the norm was determined in 40.9% of the surveyed, which may indicate the presence of transitional and late-stage hypertension, 62.2% of such persons have an accelerated type of aging of the cardiovascular system. The proportion of persons with accelerated type of aging of the respiratory system significantly (p<0.05) exceeded the proportion of persons with normal and delayed type of aging. The proportion of persons with an accelerated rate of aging was significantly higher in persons with a duration of static balancing below the standard (79.1% [71.5–86.7] versus 20.9% [13.3–28.5], p=0.009).Conclusions. Accelerated rates of aging of cardiovascular, respiratory and neuropsychic systems, low functionality of the body can be regarded as a manifestation of occupational stress. The discrepancy between the subjective assessment of their health and objective indicators of the rate of aging, the level of somatic health can be caused by the socio-psychological characteristics of the service and the tightening of medical requirements for police officers.

Постоянно растущий интерес к разработке новых неинвазивных и безманжетных методов измерения параметров сердечной деятельности, использование которых давало бы возможность непрерывного и удаленного контроля сердечно-сосудистой системы, обуславливает актуальность данной работы. В многочисленных публикациях продолжаются обсуждения преимуществ и недостатков различных методов ранней диагностики сердечно-сосудистых заболеваний. Однако артефакты движения являются сильной помехой, мешающей точной оценке показателей функционирования сердечно-сосудистой системы. Одним из перспективных методов контроля является метод оценки физиологических параметров с использованием фотоплетизмографии. Данная статья посвящена разработке устройства для фотоплетизмографических исследований и алгоритмических методов обработки регистрируемых сигналов для обеспечения мониторинга сердечного ритма с заданной точностью. В работе используются технологии цифровой адаптивной фильтрации полученных сигналов для мониторинга сердечного ритма в условиях внешних механических и электрических помеховых воздействий, ухудшающих точностные характеристики системы, а также разработана архитектура системы и изготовлен макет устройства, который позволил провести измерения для определения оптимального алгоритма цифровой обработки сигналов. При использовании устройства применялись методы адаптивной фильтрации на основе фильтров Винера, фильтров на основе метода наименьших квадратов и Калмановской фильтрации. Разработанное устройство для фотоплетизмографических исследований обеспечило возможность мониторинга сердечного ритма с заданной точностью, контроля текущего состояния организма и может быть использовано в качестве средства диагностики заболеваний сердца The constantly growing interest in the development of new non-invasive and cuff-free methods for measuring the parameters of cardiac activity, the use of which would give the possibility of continuous and remote monitoring of the cardiovascular system, determines the relevance of this work. Numerous publications continue to discuss the advantages and disadvantages of various methods of early diagnosis of cardiovascular disease. However, motion artifacts are a strong hindrance to the accurate assessment of the performance of the cardiovascular system. One of the promising control methods is the method for assessing physiological parameters using photoplethysmography. This article is devoted to the development of a device for photoplethysmographic studies and algorithmic methods for processing recorded signals to ensure monitoring of the heart rate with a given accuracy. The work uses technologies of digital adaptive filtering of the received signals to monitor the heart rate in conditions of external mechanical and electrical interference, which worsen the accuracy characteristics of the system, as well as the architecture of the system and a prototype of the device, which made it possible to carry out measurements to determine the optimal algorithm for digital signal processing. When using the device, the methods of adaptive filtering based on Wiener filters, filters based on the least squares method and Kalman filtering were used. The developed device for photoplethysmographic studies provided the ability to monitor the heart rate with a given accuracy, control the current state of the body and can be used as a means of diagnosing heart diseases

PurposeTo add to the existing body of knowledge on the relationship between stress and job performance in policing, we monitored police officers' physiology using Hexoskin shirts while they responded to simulated scenarios.Design/methodology/approachWe employed mixed repeated measures (baseline, intervention, post-intervention), between groups (treatment vs control group) design. Using this approach, our aims were (1) to determine whether an individualized physiological stress profile—a combination of heart rate (HR), heart rate variability (HRV), sympathetic nervous system (SNS) index and parasympathetic nervous system (PNS) index—could be developed for each participant; (2) to investigate the association between physiological stress and scenario performance and (3) to pilot test an intervention for decreasing physiological stress in real time.FindingsWe found that it was possible to individualize physiological stress profiles for each participant that alerted us when the participant was becoming stressed. We also found that physiological stress was significantly and negatively/inversely associated with scenario performance. However, our intervention to try and decrease participants' stress in real time was not successful. Several key lessons can be taken from our attempt that could inform future efforts in this area.Research limitations/implicationsThis was a small pilot study, precluding generalizability of results. Furthermore, our intervention was simplistic and potentially affected by an experimenter effect. Future research should explore better ways to intervene when officers are becoming physiologically stressed to help them overcome stress in real time and safeguard against the cumulative effects of stress on health and performance.Originality/valueThis research adds to the body of knowledge on physiological stress and job-task performance in police officers.

Of all the methods of studying cranial blood circulation, which I will not list here, the best is the one in which the state of cranial blood circulation is judged by the blood pressure in the two ends of the carotid artery. Hrthle was the first to observe this method, and therefore the method itself is often called the Hrthle method. However, as Hrthle himself says, the idea of ​​a method existed before. So, A. Dastre and J. Morat, for the purpose of proving the existence of vasomotor fibers for the lower limb in n. ischiadicus, determined the blood pressure in the central end of one a. cruralis and in the peripheral end the other; on the side last n. ischiadicus overcame. With irritation of a peripheral nerve cut, the pressure increased in the peripheral end of the а. cruralis, remaining unchanged in the central cut. This increase in pressure in the operated limb, which coincides with the unchanged pressure in the rest of the body, proves that (with the indicated irritation) there is a reduction in small arteries.

Abstract The aim of this study was to test the impact of the Grasping Test (GT) on the female cardiovascular system and to ascertain the possibility of using this to replace the Orthostatic Tolerance Test (OT). In this study, 15 volunteer female students were examined, and their physiological parameters - their systolic (SBP) and diastolic blood pressures (DBP), and their heart rates (HR) - were compared. We found that the Orthostatic Tolerance Test (changing the position of the body from recumbent to upright) and the Grasping Test induced meaningful but similar changes in the functioning of the women’s cardiovascular system. The results confirm that there were significant similarities between the cardiovascular system measurements as produced through the Orthostatic Tolerance Test and the Grasping Test. The possibility of introducing the procedure into clinical practice is a crucial factor for continuing our research in the wider population.

Taxes<em> have been the bedrock of revenue generation to any government. The administration of tax is very important to any government as it is the body responsible for implementing and governing the tax laws and other tax related to assessment, collection and remittance of tax. This study is aimed at ascertaining the effect of tax administration on revenue generation in Gombe state. The study uses survey research design. The primary source of data collection was adopted, which analysed using descriptive statistics was made up of frequencies and simple percentages. Cronbach's Alpha diagnose was carried out to seek for reliability of the questions contained in the questionnaire Three Hypotheses were presented in this research and were tested using Spearman’s Rank correlation, Pearson correlation and linear regression. Research findings indicated that Tax Administration in the state is not efficient and effective. The study revealed further that revenue generated in the state is low to meet its objectives due to low level of enlightenment of tax payers and incidents of tax evasion and tax avoidance. To this end, the study recommends, among others, that authorities should embark on more enlightenment campaign of citizens on the significance of paying Personal Income Tax, the quality and efficiency of tax workers should be improved so that more effective administration will be achieved and automation of the system.</em>

The condition of the cardiovascular system is one of the important criteria for assessing the impact of sports training on the human body. According to the indicators characterizing the state of the cardiovascular system, it is possible to trace the changes associated with fluctuations in the level of training, as well as to identify signs of overload as early as possible. The study of adaptive reactions of the cardiovascular system in athletes under physical activity is an important indicator for sports practice. The purpose of the study was to investigate the quantitative criteria for assessing the state of the cardiovascular system and approaches to correct the functional state of qualified athletes specializing in table tennis. Materials and methods. Studies of heart rate variability, quantitative and qualitative indicators that sufficiently reflect the autonomic functions of the body were used in order to assess the state of autonomic regulation in highly qualified athletes. Systematic physical activity causes a significant restructuring of the cardiovascular system and leads to morphofunctional changes in the mechanisms of the heart. Depending on the autonomic regulation of heart rhythm, there are different ways of myocardial adaptation processes. The balance of sympathetic and parasympathetic links of autonomic rhythm regulation is reflected in the activation of the left ventricle. Results and discussion. Adaptive changes of the cardiovascular system to competitive and training loads in the competitive period in qualified athletes are characterized by a significant decrease in heart rate (from 84.75±1.74 beats / min to 74.8±0.38 beats / min). In addition, a significantly faster process of restoring heart rate was established after exercise in the group of qualified athletes, compared with athletes of the category 1 at 4 (p >0.05) and 5 (p >0.05) minutes, respectively. According to the indicators of autonomic regulation of heart rhythm, activation of the parasympathetic link prevails in athletes of the category 1 in comparison with qualified athletes activation (according to high-frequency component, p <0.05). Significantly higher rates of individual parts of the body compared to low-skilled athletes were found out: the hormonal system (the indicator responsible for the hormonal part of the body – very low-frequency component) and the nervous system (indicators of the sympathetic nervous system – low frequency component). There are significantly higher values of the magnitude of the heart rate spectrum and high-frequency component at p <0.05, which indicates a higher power of all units of the parasympathetic regulation in the category 1 in relation to masters of sports and candidates masters of sports. Conclusion. Systematic physical activity causes a significant restructuring of the cardiovascular system and leads to morphofunctional changes in the mechanisms of the heart. Depending on the autonomic regulation of heart rhythm, there are different ways of myocardial adaptation processes. The balance of sympathetic and parasympathetic links of autonomic rhythm regulation is reflected in the activation of the left ventricle. The analysis showed that the spectral characteristics of heart rate variability significantly differ between groups of athletes with different dominance that are observed only in terms of high-frequency component, which in turn led to a change in the sympathetic-vagal balance

The aim of the research is to examine the relationship between the integral parameters of respiratory function, the values of LPO-AOD system and NO level at bronchopulmonary pathology in individuals living in different ecological areas of the city of Vladivostok. 206 patients living in different ecological conditions (healthy individuals, patients with respiratory disorders) were examined. Lung function and the state of LPO-AOD system were studied; the concentration of NO metabolites was assessed in blood serum. The nature and strength of the impact of environmental factors on respiratory function, the state of LPO-AOD, NO level were studied by the method based on correlation analysis. There was calculated power index (D) which was differentiated into power within the system (Ds) which in its turn reflects the in-system interrelationship tension (LPO-AOD, respiratory) and power between systems (Dm) characterizing the activity of interconnections and response to an external stimulus. Intra-system dependences typical for the unfavorable zone were viewed in relation to the favorable zone. It was found out that in ecologically unfavorable regions in individuals with different bronchopulmonary pathologies the value of Ds increases. This indicates that the pathogenic influence of environmental factors increases. In healthy people living in ecologically unfavourable area physiological adaptive-compensatory reaction of the body was revealed, which was proved by high power interconnections (Dm). In the patients with chronic bronchitis there was maintained an adequate level of functioning of the body systems studied. In patients with COPD living in an unfavourable zone there were found strong links between the indicators of the system of LPO-AOD and of NO, and in patients with bronchial asthma - supplementary relationship between lung function and NO. At the same time pathologic changes in the system of LPO-AOD and NO depend on the general pollution, metal and gas components contained in the air. Thus, the people with respiratory diseases being in environmentally unfavorable conditions have the most negative influence. The analysis of the activity of relationships proved that violations of interaction of LPO-AOD systems and NO in ecologically unfavorable regions may contribute to the occurrence and progression of bronchopulmonary diseases.

Sport has accompanied mankind since ancient times. It is thanks to sport that we are healthier and can enjoy life. The smallest sporting effort causes the body to produce endorphins that make us feel happy. Not without significance is the fact that sport, but in its professional dimension, prepares people who practice it to a great effort. In the face of threats, unforeseen events, people who practice sports can find their way around the situation and take appropriate actions. Therefore, just as police officers face difficult service in the present day, police officers had to face up to the challenges posed in the interwar period. In 1918 Poland regained its independence, and the authorities were responsible for ensuring the security of the country. Therefore, on 24 July 1919, the State Police was established by law. Due to the nature of the tasks performed, the police officers were required to be physically fit. In order to meet this challenge, pro-sports organizations were established, which by their actions were to raise the level of sports skills of both the society and the officers. The factor which was to motivate uniformed officers to work on their physical fitness was the introduction of the National Police Sports Competitions, which were nationwide in scope. Undoubtedly, this form of competition, as well as mobilization, led to the fact that on the basis of Police Sports Clubs, physical culture in the State Police significantly developed. The article presents the face of sport in the interwar period in the Polish State Police, its development and influence on the officers themselves, as well as its further importance in the history of sport in Poland.
