The features of tolerance to acute hypoxia by individuals with different levels of trait anxiety are presented. It was established that changes in such physiological parameters as heart rate in individuals with a high level of personal anxiety are more pronounced in hypoxic conditions. In particular, in this group, by the 25th minute of lifting in the altitude training chamber to a height of 5000 m, the heart rate increased by an average of 38.1% (p<0,01) of background values. In persons with a low level of trait anxiety, an increase in heart rate does not exceed an average 32% (p<0,01). However, in subjects with a high level of trait anxiety, compared with people with a low level of trait anxiety, a more pronounced increase in the Rufie index at an average of 18,2% (p<0,01). In addition, in individuals with a high level of trait anxiety, a more pronounced slowing-down time of a complex sensorimotor reaction by 33,0 ms (p<0,05) from the background value was observed, while in people with a low level of trait anxiety, on average, only by 20,2 ms (p<0,05). Thus, changes in individual physiological parameters in individuals with a high level of trait anxiety are more pronounced, their functional state is less tolerant to the hypoxia effect, and the level of physical performance is lower on average in this group.

Features of hypoxia tolerability by persons with different levels of neurotism are presented. It was found that changes on physiological parameters such as heart rate, arterial pressure and saturation of arterial blood in persons with a high level of neurotism are more pronounced in conditions of hypoxia. In particular, to the 25-30th min. when they stay in altitude chamber, heart rate is enlarged by 38% (p0,01) from initial. The persons with the low level of a neyrotizm, the augmentation of heart rate doesn’t exceed 28% (p0,01). This compensatory physiological reaction helps maintain arterial blood saturation in people with high neurotism by 5,3% (p0,05) more, at people with a low degree of neurotism. However, at the same time at examinees with a high level of neurotism, in comparison with persons with the low level of a neyrotizm more expressed decrease of working capacity of a myocardium on 23,4%. In addition, in persons with a high degree of neurotism, there is a more pronounced negative dynamics of an increase in the time of a complex sensomotorny reaction to 41,57 ms (p0,05) from background level, while in persons with low neurotism only by 26,19 ms (p0,05). Thus, at assessment of an acceptability of a hypoxia, it is necessary to take into account the dependence of changes physiological and psychophysiological indicators and also physical effeciency of heart from degree neyrotizm.

An increase in the prevalence of insulin resistance in the elderly, associated with physiological changes in carbohydrate metabolism during the aging process, is associated with a high risk of cardiovascular accidents and endocrine diseases. This problem requires a solution by healthcare professionals with medication and non-medication. The purpose of the study was to determine the effectiveness of the program of physical therapy by the dynamics of indicators of the cardiovascular system, carbohydrate and lipid metabolism, psychoemotional status of elderly people with frailty and metabolic syndrome. Material and methods. 96 elderly people were examined. The control group consisted of persons without metabolic syndrome and without frailty. The main group 1 consisted of patients with metabolic syndrome and frailty with a low level of therapeutic alliance who did not want to cooperate with a physical therapist and / or actively improve their health on their own. The main group 2 included patients who agreed to undergo a developed program of physical therapy (a high level of therapeutic alliance) using kinesitherapy, massage, nutritional correction, education of the patient and his family, elements of cognitive training and occupational therapy for 1 year. The effectiveness of the program was assessed by the dynamics of systolic and diastolic blood pressure, heart rate, Kvass endurance coefficient, Baevsky's adaptive potential, Robinson's index, physical performance (based on the results of a 6-minute test), carbohydrate parameters (fasting blood glucose and after glucose load) and lipid (concentration of cholesterol, triglycerides, high density lipoproteins) metabolism, the level of depression according to the GDS-15 questionnaire. Results and discussion. In elderly people with frailty and metabolic syndrome, a statistically significant (p <0.05) deterioration in the parameters of the functioning of the cardiovascular system (according to the levels of DBP, heart rate at rest, Kvass endurance coefficient, Baevsky's adaptive potential, Robinson's index), physical performance (according to the results of a 6-minute test - distance, severity of fatigue, shortness of breath, cardialgia), biochemical parameters (fasting hyperglycemia, impaired glucose tolerance, atherogenic dyslipidemia), psycho-emotional state (depression) from their peers. The use of physical therapy tools led to a statistically significant improvement (p <0.05) of all the studied parameters of the functioning of the cardiovascular system, biochemical parameters in elderly people with metabolic syndrome and frailty, an increase in their physical performance, and an improvement in psycho-emotional status. A low level of therapeutic / rehabilitative alliance led to unsatisfactory fulfillment or non-fulfillment of the recommendations provided by patients and is associated with a lack of improvement in the state of the cardiovascular system, physical performance, age-associated depression. Conclusion. It is advisable to include physical therapy means in the rehabilitation programs for elderly patients with comorbid pathology like frailty and metabolic syndrome for the prevention of cardiovascular accidents

We tested the hypothesis that individual differences in the effect of acute hypoxia on the cardiovagal arterial baroreflex would determine individual susceptibility to hypoxic syncope. In 16 healthy, nonsmoking, normotensive subjects (8 women, 8 men, age 20–33 yr), we assessed orthostatic tolerance with a 20-min 60° head-upright tilt during both normoxia and hypoxia (breathing 12% O2). On a separate occasion, we assessed baroreflex control of heart rate (cardiovagal baroreflex gain) using the modified Oxford technique during both normoxia and hypoxia. When subjects were tilted under hypoxic conditions, 5 of the 16 developed presyncopal signs or symptoms, and the 20-min tilt had to be terminated. These “fainters” had comparable cardiovagal baroreflex gain to “nonfainters” under both normoxic and hypoxic conditions (normoxia, fainters: −1.2 ± 0.2, nonfainters: −1.0 ± 0.2 beats·min−1·mmHg−1, P = 0.252; hypoxia, fainters: −1.3 ± 0.2, nonfainters: −1.0 ± 0.1 beats·min−1·mmHg−1, P = 0.208). Furthermore, hypoxia did not alter cardiovagal baroreflex gain in either group (both P > 0.8). It appears from these observations that hypoxic syncope results from the superimposed vasodilator effects of hypoxia on the cardiovascular system and not from a hypoxia-induced maladjustment in baroreflex control of heart rate.

Effects of hypothermia on the character of changes in central hemodynamics, heart rate variability (HRV) and EEG were studied during an experimental whole-body cooling of 30 healthy male subjects at the age of 18–20 years. The subjects were divided into 2 equal groups by the median body temperature in the total sample (34.1 °С) during cooling. The experiment consisted of 3 steps: rest at +20 °С, 10-min exposure to -20 °С in a hypothermal chamber and rewarming at +20 °С. The parameters registered at each step included EEG, blood pressure (BP), heart rate (HR) and temperature in the external auditory meatus. In the cooling chamber, body temperature lowered reliably by 1.4–3.1 °С on the average. In both groups hypothermia reduced the index of regulatory systems strain, increased total HRV power and BP, and decreased HR. During rewarming all these parameters tended to return to baseline values. Subjects with a more distinct hypothermia (33.1 °С) displayed a weakened baroreflex reaction (slight HR reduction) accompanied by a stronger vascular reaction (significant BP rise). High baroreflex stability in the subjects with low-level hypothermia (35 °С) was evidenced by a significant HR decrease in response to the BP rise. Changes in the EEG amplitude and frequency patterns during cooling declared themselves by enhancement of the subcortex regulatory activity (reliable rise in the theta-activity). Also, the alpha-activity was increased in the subjects with high-level hypothermia and decreased in 73 % of the subjects with a low-level hypothermia which points to desynchronization of the main rhythm.

The study involved 32 children aged from 11-12 who were receiving training in sports schools in Sumy .The children were divided into three study groups with high, medium and low levels of sensorimotor reactivity, defined in terms of complex visual-motor response. The study methods were psychophysiological, cardiointervalography, mathematical and statistical. We found that the majority of individuals with a medium level of sensorimotor reactivity possessed vegetative tonus, characterized by background emphotony, while sympathicotonia was prevalent in the group of athletes with a high level of sensorimotor reactivity, in comparison with those with medium and low levels of sensorimotor reactivity. Vegetative imbalance that manifests via hypersympaticotonic reactivity occurred among athletes with high and medium levels of sensorimotor reactivity, which is the evidence of stress on the cardiovascular system, decline of adaptive capacity of the organism in the individuals investigated. Shorter latent periods of complex visual-motor responses (LP SR 1–3 and LP SR 2–3) were observed among athletes with hypersympaticotonic vegetative reactivity, compared to sportsmen with normal type of vegetative reactivity (P < 0.05). Analysis of indicators of heart rate variability revealed an increased activity of the sympathoadrenal system in athletes with a high level of sensorymotor response, which is confirmed by significantly lower values of SDNN and RMSSD in comparison with athletes with a low level of sensorymotor response. The activation of central regulation in athletes with a high level of sensorimotor responses also show significantly higher values IN and Amo, in comparison with athletes with a low level of sensorymotor response. The figures IN (47.7%), and Amo (45.3%) were those most effected by the level of sensorimotor reactivity. Less effected were figures of SDNN (43.1%), which reflects general heart rate variability and RMSSD (43.1%), which reflects high frequency components of heart rate. Analysis of change in dynamics of figures of heart rate variability provides evidence of higher activity of the sympathoadrenal system in athletes with a high level of sensorimotor reactivity, which facilitates increased stress on heart rhythm vegetative regulation mechanisms, accompanied by decline of parasympathetic influences of the vegetative nervous system.

Oligohydramnios is an obstetric pathology being one of the most common perinatal diseases. In 70% of cases, its causes are unclear which requires further improvement of diagnostics and treatment tactics. The objective of the research was to examine psychoemotional state in pregnant women with oligohydramnios.Materials and methods. 120 pregnant women with oligohydramnios diagnosed at 27-29 weeks of gestation were examined. The control group included 30 somatically healthy women with physiological course of pregnancy. Psychoemotional state of women was evaluated using the survey and the scale proposed by S.D. Spilberg and adapted by Yu.A. Khanin. Results. When studying psychological peculiarities, we did not reveal realiable differences in the level of trait anxiety between women with oligohydramnios and pregnant women without it. Moreover, there was observed a similar division of patients by the low, medium and high levels of this indicator among patients of both groups. However, the analysis of the obtained data showed the increase in the level of state anxiety in the main group (43.28±1.36 points) compared to the control one (35.30±2.22 points, p<0.01). Among women with oligohydramnios, an increase in the proportion of individuals with a high level of this parameter (p<0.01) as well as a decrease in the proportion of individuals with a low level of this parameter was observed.Conclusions. The level of trait anxiety in pregnant women with oligohydramnios did not differfrom that in healthy women and corresponded to the average value, while the level of state anxiety which corresponded to the average values as well, significantly increased compared to pregnant women with physiological gestation (p<0.01). Among this category of patients, a statistically significant increase in the proportion of individuals with a high level of this parameter was observed (p<0.01).

Milk is an important intake to meet nutritional needs. Both consumed by children, and adults. Indonesia has many producers of fresh milk, but it is not sufficient for national milk needs. Data mining is a science in the field of computers that is widely used in research. one of the data mining techniques is Clustering. Clustering is a method by grouping data. The Clustering method will be more optimal if you use a lot of data. Data to be used are provincial data in Indonesia from 2000 to 2017 obtained from the Central Statistics Agency. The results of this study are in Clusters based on 2 milk-producing groups, namely high-dairy producers and low-milk producing regions. From 27 data on fresh milk production in Indonesia, two high-level provinces can be obtained, namely: West Java and East Java. And 25 others were added in 7 provinces which did not follow the calculation of the K-Means Clustering Algorithm, including in the low level cluster.

The author analyzes definitions of the concepts of determinants of crime given by various scientists and offers her definition. In this study, determinants of crime are understood as a set of its causes, the circumstances that contribute committing them, as well as the dynamics of crime. It is noted that the Russian legislator in Article 244 of the Criminal Code defines the object of this criminal assault as public morality. Despite the use of evaluative concepts both in the disposition of this norm and in determining the specific object of a given crime, the position of criminologists is unequivocal: crimes of this kind are immoral and are in irreconcilable conflict with generally accepted moral and legal norms. In the paper, some views are considered with regard to making value judgments which could hardly apply to legal norms. According to the author, the reasons for abuse of the bodies of the dead include economic problems of the subject of a crime, a low level of culture and legal awareness; this list is not exhaustive. The main circumstances that contribute committing abuse of the bodies of the dead and their burial places are the following: low income and unemployment, low level of criminological prevention, poor maintenance and protection of medical institutions and cemeteries due to underperformance of state and municipal bodies. The list of circumstances is also open-ended. Due to some factors, including a high level of latency, it is not possible to reflect the dynamics of such crimes objectively. At the same time, identification of the determinants of abuse of the bodies of the dead will reduce the number of such crimes.
