Pulp hyperemia: analysis of treatment based on the results of a survey of dentists

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.

Rhinological Status of Patients with Nasolacrimal Duct Obstruction

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.

Relationship between emotional intelligence and self-actualization in managers of a trading company

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.

ASSESSMENT OF THE ENVIRONMENTAL SAFETY FACTORS OF PLAY-GROUNDS USING THE RANK CORRELATION METHOD

The process of rapid development in modern cities has led to a significant number of playgrounds being located in confined areas, near roads with heavy vehicle traffic (including tram tracks), next to short-term parking spaces and refuse containers. Particular attention is paid to unauthorised parking which is caused by a lack of designated parking spaces. In addition, in residential areas of modern megacities there is a lot of infill development, which is an additional source of noise and dust. Thus, a significant number of playgrounds are located in areas with excessive anthropogenic load. The materials presented in the article describe the current condition of playgrounds in most big cities of Ukraine. Particular importance is attached to the factors which are connected with vehicle traffic, for example noise pollution, air dustiness and pollutant emissions. At the first stage, a list of factors affecting the environmental safety of children's playgrounds in urbanised areas was compiled and analysed. The next stage involves the development of a questionnaire and the direct assessment of the influencing factors by the experts involved. The article considers the factors that are rarely considered in the study of the impact of individual anthropogenic factors of the environment on public health, however, in modern conditions they cannot be neglected. The final stage consists of data processing and formation of conclusions. Using the method of rank correlation, the main factors of influence on the objects of research are identified. The results of the research stated in the article can be used in further study of the subject and in the development of methods to eliminate the influence of the most significant factors affecting the ecological safety of children's playgrounds.

INVESTMENT ASPECTS OF CAPITALIZATION UNDER MODERN CONDITIONS OF ENTERPRISE ACTIVITY

The post-industrial specificity of social processes has led to significant changes in all spheres of economic activity, including capital formation. The immanent property of the processes and results of capitalization is their investment nature, which acquires significant changes in modern business conditions, which updated the implementation of this research. According to the results of critical analysis of the content of the category of «capitalization», scientific approaches to its definition were streamlined, which allowed further research to focus on more significant points that characterize the investment specifics of the studied phenomenon. Based on the current provisions of the theory of capitalization, which are determined on the basis of interrelated categories «Capital — Value — Growth» (in the classical interpretation of the theory of capitalization such concepts are «Capital — Cost — growth») it was found that the investment specifics of modern processes and results it is expedient to study on the basis of the concept of impact investment, which provides for the priority of investment not only in commercial but also socially oriented spheres of life, which provide socially significant and environmental effects. The study proved that the key cost results of capitalization in the current conditions of enterprises are dependent on the level of development of unfunded and dematerialized types of capital, areas of activity and investment. Based on the use of the rank correlation method, the relationship between capital formation factors and key cost indicators, calculated on the basis of the fundamental cost approach, was determined. According to the results of research of 19 industrial enterprises of Ukraine during 2009—2018, a high level of dependence between the volume of investments, value results of capital formation and indicators of the fundamental value of capital and its varieties was proved. It is determined that the consequences of investing in the development of management and communication technologies, digitalization of business processes have a fairly high level of connection with the fundamental cost of operating capital of the studied enterprises. The conclusion about strengthening of influence of intellectual and social factors on cost results of capitalization of the enterprises is made. Keywords: capitalization, investment impact, fundamental cost of capital, value results, invested capital, industrial enterprises. Formulas: 0; fig.: 3; tabl.: 0; bibl.: 15.

The Relationship Between the Strategies of Transferring the Meanings of Information Messages and the Meaning-of-Life Orientations of Social Networks Users

The aim of the work is to identify strategies for transferring the meanings of information messages used by students in social networks, and how these strategies are related to the students’ meaning-of-life orientations. The study was conducted with the use of a theoretical method, as well as a survey, a content analysis, an expert method, a psychodiagnostic method, descriptive statistics, and also nonparametric tests, the Kruskal-Wallis H-test and Spearman’s rank correlation method. Among modern youth, social networks are one of the most common sources of obtaining and distributing information. Therefore, it is important to find out what strategies for transferring the meanings of information messages are used by respondents. The expert method and content analysis allow us to identify 6 strategies for transferring meanings that students use in communication when transferring the meanings of various publications in social networks. Further analysis shows that each strategy has its own features of the meaning-of-life orientations components and significant relationships between the strategies of the meanings transferring and the components of the meaning-of-life orientations of social networks users are also revealed. Thus, we can conclude that the features of the transferring of meanings are significantly influenced by the meaning-of-life orientations, in particular, goals in life. Thus, the study emphasizes the importance of the semantic communication in social networks, the results of which can influence the effectiveness of communication, training, and the interaction among users.

The role of plum genotype in the inheritance of the trait of resistance to low negative temperatures

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.

Impact of Environmental Indicators on the COVID-19 Pandemic in Delhi, India

Currently, there is a massive debate on whether meteorological and air quality parameters play a crucial role in the transmission of COVID-19 across the globe. With this background, this study aims to evaluate the impact of air pollutants (PM2.5, PM10, CO, NO, NO2, and O3) and meteorological parameters (temperature, humidity, wind speed, and rainfall) on the spread and mortality due to the COVID-19 outbreak in Delhi from 14 Mar 2020 to 3 May 2021. The Spearman’s rank correlation method employed on secondary data shows a significant correlation between the COVID-19 incidences and the PM2.5, PM10, CO, NO, NO2, and O3 concentrations. Amongst the four meteorological parameters, temperature is strongly correlated with COVID-19 infections and deaths during the three phases, i.e., pre-lockdown (14 March 2020 to 24 March 2020) (r = 0.79), lockdown (25 March 2020 to 31 May 2020) (r = 0.87), and unlock (1 June 2020 to 3 May 2021) (r = −0.75), explaining the variability of about 20–30% in the lockdown period and 18–19% in the unlock period. NO2 explained the maximum variability of 10% and 7% in the total confirmed cases and deaths among the air pollutants, respectively. A generalized linear model could explain 80% and 71% of the variability in confirmed cases and deaths during the lockdown and 82% and 81% variability in the unlock phase, respectively. These findings suggest that these factors may contribute to the transmission of the COVID-19 and its associated deaths. The study results would enhance the ongoing research related to the influence of environmental factors. They would be helpful for policymakers in managing the outbreak of COVID-19 in Delhi, India.

EXPERIMENTAL VERIFICATION OF THE AUTHOR'S PROGRAM OF PSYCHOCORRECTION OF EMOTIONAL STATES OF ELDERLY WOMEN WITH PARTICULAR HEART DISEASE

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.
