To assess the degree of inheritance in plum genotypes of the trait of resistance to the effects of damaging environmental factors of the cold season (after a thaw and after a thaw with subsequent hardening) and to identify forms with high resistance to low negative temperatures, in 2019-2020 an experiment on freezing under controlled conditions was set up (climatic chamber TH-6 (JEIO TECH, Korea)). The objects of the experiment were one-year shoots of seedlings of three hybrid families obtained as a result of controlled hybridization in 2016 (UB 8 × Smolinka, Kubanskaya Kometa × Utro, Kubanskaya Kometa × Smolinka), as well as parental varieties: Kubanskaya Kometa, Smolinka, Utro and hybrid UB 8 with various forms of field resistance to low negative temperatures (based on average long-term observations in 2007-2015) and with high indicators of agronomic valuable traits. For each component of the study of winter hardiness, the temperature regimes of freezing were selected: -22 °C for 15 hours after 5 days of thaw +3 °C (III component); -34 °C after 5 days of thaw and subsequent hardening at -5 °C within 5 days, then at -10 °C for 5 days (IV component). As a result of assessing the resistance of the hybrids to low negative temperatures, it was noted that after the thaw 73 % of the hybrids showed no damage; after a thaw followed by hardening, the total degree of freezing of hybrids varied from 0.5 points (UB 8 × Smolinka, form No. 10) to 4 points (UB 8 × Smolinka, form No. 4). Genotypes resistant to temperature changes from positive to negative with hardening from families UB 8 × Smolinka (forms No. 1, 10), Kubanskaya Kometa × Utro (form No. 3), Kubanskaya Kometa × Smolinka (form No. 2) are of interest for further breeding research. Assessment of the influence of the genome of parental forms on inheritance in hybrids of resistance to low negative temperatures according to component IV using the Spearman rank correlation method revealed an average direct insignificant correlation between winter hardiness in parental forms and hybrids.

The aim of the study is to determine the psychological mechanisms of the connection between emotional and volitional self-regulation and role competence of students.Methods. Analysis of average data and correlation (by Spearman’s rank correlation method) between scales of 5 methods of research: 1) study of features and levels of development of role competence of students was carried out with use of “Questionnaire of role competence” by P. Gornostay; 2) to clarify the features of emotional-volitional regulation of role behavior, the level of emotional intelligence and its parameters such as: awareness of emotions, the ability to recognize emotions, self-motivation, empathy and emotion control were used: “Methods of diagnosing emotional intelligence” N. Hall, adapted by E. Ilyin and test-questionnaire “Study of volitional self-regulation” (A. Zverkov and E. Eidman); 3) “Methods of diagnosing the level of reflexivity” by A. Karpov was used by us to determine the level of development of the mechanism of reflection.Results. The study found that students in higher education have developed role competence at the secondary level. They have a low level of development of the integrative indicator of emotional intelligence; low level of development of ability to control one’s emotions and self-motivation, average level of development of emotional awareness and empathy, ability to recognize emotions of other people. The average general level of volitional regulation and such volitional qualities as persistence and self-control were revealed; medium and high levels of development of reflection.It is determined that the higher the level of emotional and volitional self-regulation, the higher the level of role competence. It is established that the positive factors in the formation of role competence of students of psychological and pedagogical specialties are: emotional intelligence (emotional awareness, self-motivation, emotional identification, empathy) and reflection.Conclusions. The results of the research determine the goals and objectives aimed at developing emotional and volitional components of the structure of role competence of students, which will consist in the formation of emotional and volitional characteristics connect with role competence (ability to emotional and volitional regulation, empathy, reflectivity, volitional qualities).Key words: role competence, psychological mechanisms, emotional-volitional self-regulation, empathy, reflection, student.

The purpose of this article is to analyze the effect that halving has on the fair market value of bitcoins. The main hypothesis of the study is that the decline in the cost of miners’ remuneration for mining is a significant factor that affects the price of cryptocurrencies. The article examines the factors that regulate the issuing process. The significance of a limited supply of bitcoin is detailed in the article, as well as the mechanism for the implementation of the issue of new bitcoins. The study compares the historical inflation data of the US dollar and the projected data on the inflation of bitcoin. The article analyzes the main technical element of cryptocurrency – halving – when the miner’s reward is halved. This analysis includes the mathematical methods of statistical data processing. Research results show that reducing remuneration by half every four years leads to an increased market value of the cryptocurrency. This relationship is clearly illustrated by the Kendall rank correlation method. The results of the study can have a significant impact on the fundamental assessment of bitcoin and can also enable investors to assess any of the existing and operating cryptocurrencies according to this method.

Abstract Introduction Studying the state of the nasal cavity and its sinuses and the morphometric parameters of the inferior nasal conchae, as well as a comparative analysis of obtained values in patients with primary (PANDO) and secondary acquired nasolacrimal duct obstruction (SALDO), is relevant. Objective To study the rhinological status of patients with PANDO) and SALDO). Methods The present study was based on the results of computed tomography (CT) dacryocystography in patients with PANDO (n = 45) and SALDO due to exposure to radioactive iodine (n = 14). The control group included CT images of paranasal sinuses in patients with no pathology (n = 49). Rhinological status according to the Newman and Lund-Mackay scales and volume of the inferior nasal conchae were assessed. Statistical processing included nonparametric statistics methods; χ2 Pearson test; and the Spearman rank correlation method. Results The difference in values of the Newman and Lund-Mackay scales for the tested groups was significant. A significant difference in scores by the Newman scale was revealed when comparing the results of patients with SALDO and PANDO. Comparing the scores by the Lund-Mackay scale, a significant difference was found between the results of patients with SALDO and PANDO and between the results of patients with PANDO and the control group. Conclusion It was demonstrated that the rhinological status of patients with PANDO was worse than that of patients with SALDO and of subjects in the control group. No connection was found between the volume of the inferior nasal conchae and the development of lacrimal duct obstruction.

D-Dimer assays measure specific breakdown products of crosslinked fibrin whereas FDP assays are not specific for these products. We have, therefore, measured D-Dimer levels (MabCo Dimer Test) semi-quantitatively in patients with clinical and laboratory evidence of disseminated intravascular coagulation, acute and chronic liver disease, acute leukaemia at presentation and acute venous thrombosis at diagnosis. We have also measured D-Dimer in the 3rd trimester of normal pregnancy and in pregnancies with complications. We compared these levels with F.D.P. levels measured by the Thrombo-Wellcotest. Patients with liver disease comprised mainly cirrhosis and acute viral hepatitis; those with venous thrombosis had this diagnosis confirmed by venography. Pregnancy complications included mainly pre-eclampsia, ante-partum haemorrhage and intra-uterine foetal death. D-Dimer levels were elevated ( 200ng/ml) in all 31 patients with D.I.C., in 34 of 40 with liver disease, in 13 of 16 with acute leukaemia, in all 10 patients with D.V.T., in 9 of 16 normal pregnancies and in 29 of 39 complicated pregnancies. Using a rank correlation method, there was correlation between D-Dimer and F.D.P. levels (Normal 8ug/ml) in the following groups of patients as follows (r is the correlation coefficient, levels of significance are shown in brackets):D.I.C. r=0.72(0.2%), liver disease r=0.56(0.2%), acute leukaemia r=0.72(0.2%), D.V.T. r=0.83(1%) and complicated pregnancy r=0.42(1)6). There was no correlation between D-Dimer and F.D.P. levels in normal pregnancy. Very rarely were D-Dimer levels elevated when F.D.P. levels were normal and vice-versa. We conclude that a close relationship does exist between D-Dimer and F.D.P. levels in the clinical conditions that we have studied. We note the high incidence of elevated D-Dimer levels and the close correlation with F.D.P. levels in patients with liver disease and the high incidence of elevated D-Dimer levels suggesting increased activity of the coagulation system in patients with acute leukaemia.

The purpose of the study: to analyze the methods of treatment of deep caries by dentists of the Samara region.Materials and methods. In 2021, 220 specialists of the Samara region were surveyed on the treatment of deep dental caries on the bases of budgetary and extra-budgetary organizations. The questionnaires contained 20 questions that provided information about the level of professional training of specialists, the degree of their awareness of quality criteria and standards, the use of modern technologies and the implementation of each stage of deep caries treatment. The statistical significance of the obtained results (p) was calculated using the Student’s criterion (t) and its interpretation based on the standard table of critical values of the Student’s coefficient. Spearman’s rank correlation method was used to determine the strength and direction of the correlation.Results. The majority of dentists – 89.9% use a medical pad in the treatment of deep caries, of which 38.7% of respondents use this pad only when accidentally opening the tooth cavity. Based on the answers to the questionnaire, 77.0% of respondents prefer calcium-containing self-hardening medical pads and only 4.6% use MTA-based pads. A comparative analysis of doctors with rare early complications and doctors with frequent early complications showed that doctors of the second group apply a medical pad when opening the tooth cavity 25% more often than doctors of the first group when performing necrectomy in full volume in both groups. A comparative analysis of doctors with rare late complications and frequent late complications did not reveal a statistical significance between the imposition of a medical pad and the opening of the tooth cavity during a complete necrectomy in doctors of the first and second groups. Complications after the treatment of deep caries may be due to an incorrect interpretation of reversible and irreversible changes in the pulp, and in this regard – incorrectly chosen treatment tactics.Conclusion. The success of the treatment of deep carisea largely depends on the correct determination of reversible and irreversible changes in the pulp of the tooth.

The role of Information Technology based decision models for sustainable agriculture has gained immense prominence in recent years. Ranking of agriculture farms based on their yield plays a vital role in sustainable agriculture. In this work, an ensemble decision-making model, namely VIKOR (Vlsekriterijumska Optimizacija I Kompromisno Resenje), TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution), entropy, and standard deviation (VTOPES), is proposed for ranking the sustainable sugarcane farms. VTOPES system model comprises of four significant steps: (i) determination of significance scores of the sub-parameters, (ii) transformation of sub-parameter sequences into main parameter values, (iii) computation of significant scores of main parameters, and (iv) generation of assessment values and deploying it for ranking the sugarcane farms. The ranking results of the proposed VTOPES model are compared with the ranking patterns obtained from five years average yield data acquired from the selected sugarcane farms. Moreover, the outcomes of the VTOPES model are also compared with other prevalent methods. Subsequently, Spearman’s rank correlation method is applied for evaluating the impact of correlation of VTOPES ranks in comparison with the average yield ranks. Thus, it can be noticed that the empirical results of the VTOPES model provide reliable and sustainable results. Therefore, it suffices to be a sustainable decision model for any problem where multiple parameters are involved.

The elements determining the meteorological conditions are the main parameters in processes of airborne pollen modeling. In modern research the influence of different meteorological element or their complex is analyzed basing upon the statistic methods or using dispersion models in which the possible influence of meteorological parameters upon airborne pollen is described in equations. The correlation of meteorological indicators and pollen concentration in the atmosphere fixed in Klaipėda Aerobiological Station is analyzed in this article. The coefficients of correlation of meteorological parameters and pollen concentration are calculated basing upon the Spearman's rank correlation method. The analysis of various factors was used for determining the complex influence of meteorological parameters upon the pollen concentration in the air. After evaluation of influence of meteorological parameters as separate factors one has determined that more than a half of analyzed pollen types showed statistically reliable (p < 0.05) correlation of pollen amount in the air and relative air humidity (89%), air temperature (74%) and amount of precipitation (52%). The investigation results showed that 37% of pollen amount of indicated plants genera and families in the atmosphere was determined by wind velocity. After evaluation of complex influence of meteorological factors on the concentration of pollen spread in the air one has determined that relative humidity and/or air temperature are one of the most significant environmental factors determining the amount of pollen in the atmosphere during the vegetation. Their influence was determined for all the three cases under study. Santrauka Meteorologines sąlygas nusakantys elementai yra pagrindiniai parametrai modeliuojant žiedadulkių sklaidą.

The article presents the results of an experimental test of the author's program of psychocorrection of emotional states of elderly women with coronary heart disease. The main psychophysiological indicators of the emotional state of elderly women, which affect the development of coronary heart disease, are determined. These include: alexithymia, depression, openness, anxiety, neuroticism, sociability, emotional lability. The following methods of processing the obtained results were chosen, in view of the small number of respondents: Spearman's rank correlation method, Student's T-test; T - Wilcoxon test). Methods used: "Toronto Alexithymic Scale", "Hamilton Scale for Depression", "Hamilton Scale for Anxiety", "Asthenic Scales", "Neuropsychiatric Stress Questionnaire", "Aggression Questionnaire", "FR Questionnaire , according to theoretically determined indicators of the emotional sphere of elderly women with coronary heart disease. It was found that for psychophysiological indicators of depression, anxiety, neuroticism, openness, emotional lability, significance was recorded using Wilcoxon's T-test, which indicates that the change in these indicators occurred as a result of our method with a probability of more than 99%. It is noted that the level of psychophysiological indicators of alexithymia and sociability did not change significantly. We explain the weak influence of the proposed method on these indicators by objective factors. Correction of alexithymia should include a focus on the patient's awareness of their feelings and the ability to express them and should be carried out on the patient comprehensively and over a long period of time. We have identified an important cause of coronary heart disease in elderly women, which is a combination of elevated levels of negative emotions with an intense tendency to suppress their expression in social contacts and interpersonal interaction. The effectiveness of the correctional program has been proved, which can be further used by psychologists as a psychocorrectional component of the general set of measures during outpatient treatment of coronary heart disease and its psychoprophylaxis. We see the prospect of further research in the improvement of the author's comprehensive program, expansion of its corrective spectrum of action and further testing.

Introduction. The relevance of studying the emotions of employees in organizations is due to the economic and psychological crisis, as a result of which many managers are trying to cope with their stress at work and, in some cases, their job duties remotely. The study aims to examine the relationship between emotional intelligence and individual characteristics of self-actualization in managers of a large trading company. Materials and methods. Forty employees from various trade organizations took part in the study. The following methods were used: the emotional intelligence assessment technique (N. Hall) and the self-actualization test (SAT) (E. Sjostrom). Spearman rank correlation method was used. Research results. A reliable direct relationship between self-motivation and contact was obtained (rs = 0.460; p ≤ 0.05). Self-motivation, defined as managing one’s emotions, determines a person’s ability to quickly establish contacts with people and communicate. The feedback of self-motivation and self-esteem was revealed (rs = -0.555; p ≤ 0.05). According to the respondents’ evaluations, social success is not affected by a person’s ability to manage emotions and feelings. An inverse relationship of empathy and self-esteem was also revealed (rs = -0.463; p ≤ 0.05). Respondents believe that empathy with others can hinder the achievement of social success, recognition, and self-esteem. Conclusion. Emotional intelligence of employees: contributes to developing their leadership skills, increases stress resistance at work, job satisfaction, motivation, interest in organizational learning, reduces emotional exhaustion and fatigue, and is a means of conflict resolution. All this has a positive effect on the company’s efficiency.
