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 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. Nūdienos moksliniuose tyrimuose tam tikro meteorologinio elemento ar jų komplekso poveikis analizuojamas statistiniais metodaisarba taikant sklaidos modelius, kuriuose pagrindinėmis lygtimis aprašoma galima meteorologinių parametrų įtaka žiedadulkių sklaidai. Straipsnyje analizuojama meteorologinių rodiklių sąsajos su Klaipėdos aerobiologinėje stotyje fiksuota žiedadulkių koncentracija ore.

Atskirai įvertinus įvairių meteorologinių parametrų įtaką, nustatyta statistiškai patikima (p < 0,05) daugiau nei pusės analizuotų žiedadulkių tipų žiedadulkių kiekio ore ir santykinės oro drėgmės (89 %), oro temperatūros (74 %) ir kritulių kiekio (52 %) sąsaja. Tyrimo rezultatai rodė, kad vėjo greitis turi įtakos 37 % identifikuotų augalų genčių ir šeimų žiedadulkių kiekiui ore. Įvertinus kompleksinę meteorologinių veiksnių įtaką oru sklindančių žiedadulkių koncentracijai, nustatyta, kad santykinis drvgnumas ir/arba oro temperatūra yra vieni reikšmingiausių aplinkos veiksnių, lemiančių žiedadulkių kiekį atmosferoje vegetacijos metu. Резюме Элементы, описывающие метеорологические условия, являются основными параметрами в процессах моделирования дисперсии пыльцы. В современных исследованиях воздействие каждого метеорологического элемента илиих комплекса анализируется с помощью статистических методов и моделей распространения, в которых фундаментальными уравнениями описываются возможные эффекты воздействия метеорологических параметровна распространение пыльцы. Статья посвящена анализу соотношения метеорологических величин с концентрацией пыльцы, зафиксированной на аэробиологической станции Клайпеды. Коэффициенты корреляции междуметеорологическими параметрами и концентрацией пыльцы вычислены на основе метода ранговой корреляцииСпирмена. Анализ различных факторов был использован для определения комплексного влияния метеорологических параметров на концентрации пыльцы в воздухе. Оценка метеорологических параметров как отдельныхфакторов показала, что более половины анализируемых типов пыльцы свидетельствует о статистически значимой(р < 0,05) связи между пыльцой в воздухе и относительной влажностью (89%), температурой воздуха (74%) иосадками (52%). Результаты исследования показали, что скорость ветра оказывает влияние на количество ватмосфере 37% определенных семейств и родов пыльцы. Оценка комплексного влияния метеорологическихфакторов на концентрацию пыльцы в воздухе показала, что относительная влажность воздуха и(или) температуравоздуха являются одними из наиболее важных экологических факторов, определяющих количество пыльцы ватмосфере в течение вегетационного периода.

Background Anastomotic leaks significantly affect hospital stay after esophageal surgery. Here, we investigated the efficacy of early endoscopy for predicting anastomotic healing and leaks after esophageal reconstruction. Methods A total of 65 consecutive esophageal cancer patients treated by cervical esophagogastrostomy underwent routine endoscopy between postoperative days 5 and 7. The anastomosis was scored for the degree of ischemia, stenosis, and torsion of the anastomotic axis. Independent associations between ischemia, stenosis, and torsion of the proximal esophagus and the risk of the anastomotic leak were examined using Spearman's rank correlation method. Results Assessment of the degree of mucosal ischemia in 65 patients shows well healing in 35, patch ischemia in 20, diffuse ischemia in 10, no necrosis in any patient. Stenosis was classified as 0 to 10% in 40 patients, 11 to 20% in 12, 21 to 80% in 11, and 81 to 100% in 2. The degree of torsion of the anastomotic axis was classified as 0 to 10 degrees in 52 patients, 11 to 90 degrees in 8, and 91 to 180 degrees in 5. With rising endoscopy scores, there was an increase in risk for leaks (score > 4.5, sensitivity 100%, and specificity 83.8%). Conclusions Early postoperative endoscopy facilitates the management of esophagogastrostomy anastomosis to predict leaks.

The contractors sector is considered to be one of the most important sectors in terms of its effects on economic development, stabilization, and urbanization. The main objective of this study was to explore and analyze the obstacles facing the contractors sector in Saudi Arabia from the contractors’ point of view using Spearman’s rank correlation method, where the dimensionality of ordinal data was reduced by factor analysis. This required a comprehensive investigation of the obstacles that prevented contractors from completing their jobs on time, or that led to them completing a lower quality job and losing money. This study only included Saudi contractors involved with building activities and it was based on data collection using comprehensive questionnaires that defined five main factors: managerial, financial, expansion, environmental and technical. Contractors who were qualified and registered by the Ministry of Municipal and Rural Affairs (MOMRA) were considered in this study. The study concentrated on the building sector, specifically the fields and activities defined by MOMRA. Identifying the obstacles that affect professional and technical activities should help to improve performance and address various problems. A digital interactive structural questionnaire was designed and distributed via the internet to collect responses from the participants where a Likert scale-based method was used. The results obtained using the questionnaires are presented as tables and figures.

The current study aims to distinguish objects and events, which teens and adolescents include in their life's spaces, explore differences in attitudes towards life spaces, and determine the level of life's space satisfaction of the youth via narrative psycholinguistic research. Methods: Methodological approaches inhered in interviewing and content analysis of the texts by calculating the frequency and investigating the components of the life's space category references that were defined based on the narrative compositions. The validity of categorisation was proved by propositional analysis. Spearman's rank correlation method was used. Results: The research results showed that stories people tell us holds powerful sway over their memories, behaviours, and identities. The youth's space was analysed within three content blocks: structural, interpretational, and evaluative. The structural block defined categories: people; city; habitable space; educational institution; social environment and information; activity; nature; state and patriotism; the inner world. The interpretational block analysis defined interpretational judgments and attributions of the responsibility for actions and changes in the participants' lives. The evaluative block analysis revealed the significant differences between teenagers and adolescents and between females and males in terms of life's space evaluation. Conclusions: The structure of teens’ and adolescents’ live space is similar, but its interpretation and evaluation are significantly different. Proceeding from teenage to adolescence is followed by such changes as growing dissatisfaction of the existing life's space and the wish to change it; growing internality, i.e., understanding personal responsibility of the life's space formation.

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.

Abstract The supplementary old-age pension system in Poland consists of group and individual plans. This research covers the latter, namely the individual retirement accounts and individual retirement security accounts that were introduced in 2004 and 2012 respectively. The main aim of the paper is to conduct a multidimensional comparative analysis of bank retirement products including the linguistic complexity of documents creating the retirement contracts offered to individuals by banks, and the costliness and profitability of such products in the period 2012-2019. Moreover, it identifies the dependencies between the linguistic and economic traits of retirement contracts offered by banks. The correlation analysis conducted using the Spearman’s rank correlation coefficient showed that the more readable a document of a bank contract is, the higher the interest rate is and the higher the cancellation fees. The results of the study are relevant for both financial institutions and public bodies as they show the key characteristics that may influence the demand for individual retirement products in Poland and may serve as either a stimulator or a barrier in the development of supplementary old-age pension provision.

Intracerebral hemorrhage (ICH) is the second most common subtype of stroke, and it is often associated with a high mortality rate and significant morbidity among survivors. Recent studies have shown that bilirubin, a product of heme metabolism, can exhibit cytoprotective, antioxidant and, anti-inflammatory properties. However, little is known about the role of bilirubin in combating several pathophysiological pathways caused by intracerebral bleeding in patients with ICH. In this study, data were collected retrospectively on 276 patients with ICH who were admitted to a university hospital between 5 January 2014 and 31 December 2017. We assessed the relationship between levels of total, direct, and indirect serum bilirubin and assessments of initial stroke severity and clinical outcomes by using Spearman’s rank correlation and Kruskal-Wallis H tests. A secondary examination of the carrier protein albumin was also undertaken. Our study found that higher levels of direct bilirubin were correlated with worse admission Glasgow Coma Scales (GCS) (rs = −0.17, p = 0.011), worse admission ICH Scores (rs = 0.19, p = 0.008), and worse discharge modified Rankin Scales (mRS) (rs = 0.15, p = 0.045). Direct bilirubin was still significantly correlated with discharge mRS after adjusting for temperature at admission (rs = 0.16, p = 0.047), oxygen saturation at admission (rs = 0.15, p = 0.048), white blood cell count (rs = 0.18, p = 0.023), or Troponin T (rs = 0.25, p = 0.001) using partial Spearman’s correlation. No statistical significance was found between levels of total or indirect bilirubin and assessments of stroke severity and outcomes. In contrast, higher levels of albumin were correlated with better admission GCS (rs = 0.13, p = 0.027), discharge GCS (rs = 0.15, p = 0.013), and discharge mRS (rs = −0.16, p = 0.023). We found that levels of total bilirubin, direct bilirubin, and albumin were all significantly related to discharge outcomes classified by discharge destinations (p = 0.036, p = 0.014, p = 0.016, respectively; Kruskal-Wallis H tests). In conclusion, higher direct bilirubin levels were associated with greater stroke severity at presentation and worse outcomes at discharge among patients with ICH. Higher levels of albumin were associated with lower stroke severity and better clinical outcomes. Future prospective studies on the free bioactive bilirubin are needed to better understand the intricate relationships between bilirubin and ICH.

Background. Breastfeeding is the most common way of feeding infants. Human milk contains nutrients which are necessary to provide proper growth of a child. Nowadays there aren't any recommendations to follow elimination diet in order to decrease the risk of allergy or baby colic. Only the occurrence of health problems such as lactose intolerance or cow's milk protein allergy in breastfeeding mother or infant should be a reason for eliminating dairy products from diet. It seems to be important to explore the reasons and the frequency of following milk-free diet by breastfeeding women. Objectives. The main purpose of the study was to find the reasons for following milk-free diet by breastfeeding women and making an assessment of their nutrition knowledge and food habits. Material and methods. Thirty-three breastfeeding women following milk-free diet took part in the project. The women were interviewed by the Computer Assisted Web Interview (CAWI) method with an original questionnaire. The results were developed with Spearman's rank correlation, Chi2 test and the gamma coefficient. The statistical significance level for the p-value was <0.05. Results. The main reason for following milk-free diet by the breastfeeding women was the occurrence of hypersensitivity reactions of the children's gastrointestinal system after consuming milk by mother (72% responses). After excluding milk from diet only 42% respondents declared consuming new food products or dietary supplements in order to refill the potential deficiency of nutrients. The majority of respondents also eliminated from diet highly processed food products, fast-food and the carbonated drinks. The most often declared source of information about lactation was Internet (85%). Only 12% respondents asked a nutritionist in order to get the information about breastfeeding. Conclusions. It's necessary to promote a specific nutritional advice about following milk-free diet in breastfeeding women group in order to decrease the health risk connected with low calcium diet.

Aim. To assess the clinical and immunological features in patients with chronic opisthorchiasis, depending on the duration of the infection. Methods. The first group consisted of 19 patients with the duration of the infection up to 1 year, the second group consisted of 21 patients with the duration of the infection between 1 and 5 years, the third group was formed of 23 patients with the duration of the disease more than 5 years, the control group 20 healthy individuals. Immunological research was carried out at the Clinical Diagnostic Center. Statistical processing was performed using Microsoft Excel 2010 and Statistica 6.0 software. The statistical significance of differences was determined by using the MannWhitney test (U-test) at the level of significance of p 0.05. The correlations were assessed by calculating Spearman's rank correlation coefficients.Results Clinical features of chronic opisthorchiasis were revealed in the disease duration groups of up to 1 year, from 1 year to 5 years, more than 5 years: the subclinical course was most common in the group of up to 1 year; cholangiohepatitis prevailed in the group of between 1 to 5 years, allergic skin syndrome, cholangiocholecystitis and pancreatitis dominated in the group of more than 5 years. The immune response in chronic opisthorchiasis was characterized by: up to 1 year lymphocytosis, increased levels of immunoglobulins M (IgM) and circulating immune complexes (CIC), a decrease in the number of T-lymphocytes (CD3+), as well as an increase in bactericidal activity of leukocytes (BAL); between 1 and 5 years monocytosis, increased levels of immunoglobulins M, immunoglobulins G and circulating immune complexes, a decrease in T-cytotoxic lymphocytes (CD8+) and nitro blue tetrazolium (NBT test), as well as an increase in NK cells and phagocytic activity of monocytes, more than 5 years eosinophilia. Conclusion. Common features of rearrangement of the immune system in opisthorchiasis: inflammatory changes in the hemogram, activation of humoral immunity with parallel suppression of the cellular component of the immune system, and increased phagocytosis.

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. Мета статті полягає у вивченні психологічних механізмів взаємозв’язку емоційно-вольової саморе-гуляції та рольової компетентності студентів.Методи. Аналіз середніх даних і кореляція (методом рангової кореляції Спірмена) між шкалами 5 методик дослідження: 1) вивчення особливостей і рівнів розвитку рольової компетентності студентів здійснювалося із використанням «Опитувальника рольової компетентності» П.
