On January 28, 2023, the IV meeting of the All-Russian Scientific webinar “Connecting Spaces” with international participation took place. Two reports were presented for discussion. The report “The Russian Federation in the International Decade of Indigenous Languages” was made by L. A. Ulyanitskaya and A. A. Shumkov. L. A. Ulyanitskaya reported that 155 indigenous languages are represented in Russia, but some of them are on the verge of extinction. Based on the analysis of successful cases of the revival of indigenous languages taking place in the world practice, the speakers proposed a number of measures to change the situation in Russia. A. A. Shumkov described the problems and historical dynamics of the Baltic-Finnish languages in the North-West of Russia, pointed out its connection with the policy of the Russian state at different stages of its existence, gave a characteristic the current state of languages and linked the content of the report with the problems of translation. J. V. Kosheleva in her report “Unbearable ease of translation in psychoanalysis”, referring to the history of the development of the ideas of psychoanalysis, described a number of mechanisms of the human psyche and psychoanalytic techniques of influencing it, showed the proximity of the subject area of linguistics and psychoanalysis. This perspective allowed the participants of the webinar to see the problem of the resurrection of the “fallen asleep” language not only as a socio-cultural one, usually affecting only the aspect of creating external conditions for the salvation of endangered languages, but as a psycholinguistic one, which implies taking into account intrapsychic processes.

Authors: Utomo Andrean
Published: July 2023

This study aims to analyze the effect of the Capital-Labor Ratio, Mean Years of Schooling, Corruption Perception Index, FDI to GFCF Ratio, and Trade Openness on the Incremental Capital-Output Ratio (ICOR) as a measure of investment efficiency in 8 ASEAN countries. The results of this study indicate that Capital per Worker, Corruption Perception Index, FDI to GFCF Ratio, and Trade Openness have a significant effect on ICOR in 8 ASEAN Countries. While the Mean Years of Schooling have no significant effect on ICOR in 8 ASEAN Countries. Suggestions in this study to create investment efficiency in 8 ASEAN countries are to maintain and select the growth of Capital per worker by recognizing that increasing investment in the capital-intensive sector is a critical sector with a large spillover effect on the economy, increasing the quantity and quality of education, eradicating corruption, increasing FDI flows by increasing the country's competitiveness through the creation of a conducive business climate and providing various monetary and fiscal incentive, lowering export trade barriers, and attempting to limit and substitute imported consumptive and high-dependence products by developing and producing them domestically.

Purpose

The aim of this study was to evaluate the prevalence of autonomous cortisol secretion (ACS) in patients with primary aldosteronism (PA) and its implications on cardiometabolic and surgical outcomes.

Methods

This is a retrospective multicenter study of PA patients who underwent 1 mg dexamethasone-suppression test (DST) during diagnostic workup in 21 Spanish tertiary hospitals. ACS was defined as a cortisol post-DST >1.8 µg/dL (confirmed ACS if >5 µg/dL and possible ACS if 1.8–5 µg/dL) in the absence of specific clinical features of hypercortisolism. The cardiometabolic profile was compared with a control group with ACS without PA (ACS group) matched for age and DST levels.

Results

The prevalence of ACS in the global cohort of patients with PA (n = 176) was 29% (ACS–PA; n = 51). Ten patients had confirmed ACS and 41 possible ACS. The cardiometabolic profile of ACS–PA and PA-only patients was similar, except for older age and larger tumor size of the adrenal lesion in the ACS–PA group. When comparing the ACS–PA group (n = 51) and the ACS group (n = 78), the prevalence of hypertension (OR 7.7 (2.64–22.32)) and cardiovascular events (OR 5.0 (2.29–11.07)) was higher in ACS–PA patients than in ACS patients. The coexistence of ACS in patients with PA did not affect the surgical outcomes, the proportion of biochemical cure and clinical cure being similar between ACS–PA and PA-only groups.

Conclusion

Co-secretion of cortisol and aldosterone affects almost one-third of patients with PA. Its occurrence is more frequent in patients with larger tumors and advanced age. However, the cardiometabolic and surgical outcomes of patients with ACS–PA and PA-only are similar.
The roles of anti-Müllerian hormone in breast cancer
Authors: Chen Xuan , Liu Sixuan , Peng Xue , Zong Xiangyun
Published: July 2023

Anti-Müllerian hormone (AMH) is produced and secreted by granulosa cells of growing follicles, and its main role is to inhibit the recruitment of primordial follicles, reduce the sensitivity of follicles to follicle-stimulating hormone (FSH), and regulate FSH-dependent preantral follicle growth. It has become an effective indicator of ovarian reserve in clinical practice. Research on AMH and its receptors in recent years has led to a better understanding of its role in breast cancer. AMH specifically binds to anti-Müllerian hormone receptor II (AMHRII) to activate downstream pathways and regulate gene transcription. Since AMHRII is expressed in breast cancer cells and triggers apoptosis, AMH/AMHRII may play an important role in the occurrence, treatment, and prognosis of breast cancer, which needs further research. The AMH level is a potent predictor of ovarian function after chemotherapy in premenopausal breast cancer patients older than 35 years, either for ovarian function injury or ovarian function recovery. Moreover, AMHRII has the potential to be a new marker for the molecular typing of breast cancer and a new target for breast cancer treatment, which may be a link in the downstream pathway after TP53 mutation.

Published: July 2023

Removal of detrimental contaminants from paper machine circulation waters is known to benefit process runnability and paper quality. The applicability of selective flotation to remove substances of a hydrophobic nature from paper machine circulation waters was investigated in laboratory-scale experiments. The separation efficiency of ink, stickies, and wood extractives was studied by using a flotation scheme in which the froth was generated by the white water’s inherent surface active components without any chemical addition. The removal efficiency of detrimental contaminants was considered in relation to total losses of solid materials. The results showed that while not all white waters were able to produce stabile froth, those that generated froth also exhibited substantial separation of contaminants in the froth. With a moderate removal of 10% of total solids from white waters, removal of 45% of stickies, 27% of ink, and 20 to 50% of wood extractives was observed. Higher removal of contaminants resulted in solids losses at levels that are not economically feasible in paper production. The results showed that selective white water flotation can have beneficial results for papermaking processes.
The peroxymonocarbonate anions as pulp bleaching agents. Part 2. Mechanical pulp brightening and effects of metal ions
Authors: Attiogbe Francis K. , Wang Wei , McNeillie Alastair , Francis Raymond C.
Published: July 2023

The peroxymonocarbonate mono-anion (HCO4─) is generated in solutions containing bicarbonate anions (HCO3─) and hydrogen peroxide (H2O2). The mono-anion is believed to have a pKa value of ca. 10 and as such would start dissociating to the di-anion (CO42─) at pH ca. 8. The mono-anion should demonstrate electrophilic properties, while the di-anion should be a nucleophile. Results that appear to be due to electrophilic reactions of HCO4─ were presented in Part 1 of this series for lignin model compounds (LMCs) and chemical pulps. Some evidence was also observed for nucleophilic reactions with LMCs in the pH range of 8.8 to 9.5. Results are now being presented for mechanical pulp brightening, where nucleophilic reactions were observed. Hydrogen peroxide decomposition in the HCO3─ solutions was significant on some occasions, and Fe catalyzed decomposition was the most significant contributor in both pulp slurries and pulp-free solutions.
Prospectivity of the Biostromna Zone (Northwestern Shelf of the Black Sea) for hydrocarbon exploration according to density modeling
Authors: KOZLENKO M.V. , KOZLENKO Yu.V.
Published: July 2023

In order to determine the hydrocarbon prospectivity (HC-potential) of the Biostromna zone, located on the northwestern shelf of the Black Sea, a systematic two-dimensional density (gravity) modeling was carried out along 8 submeridional profiles. Particular attention was paid to determining the location of deep faults that could be the source of methane and other hydrocarbon jets that penetrated to the earth's surface. To calculate the fluctuations in the magnitude of the gravity effect associated with changes in the density of sediments, models with minimum and maximum values of this parameter were calculated for each layer separately and for the entire sedimentary cover of the Biostromna zone. It is determined that variations in the density of the sedimentary cover lead to fluctuations in the values of model anomalies up to ±2 mGal. The conducted density modeling has shown a wide variety of basement structure within the Biostromna zone with alternating uplifted and submerged areas of the crystalline crust with a significant change in the structure of the study area in the longitudinal direction. The HC-potential of local structures of the Biostromna zone was assessed by four criteria: 1) by the distance between the base of the sedimentary cover and the roof of the granodiorite layer, since the smaller the value of this parameter, the less the dispersion of mantle material and the greater its flow to potential hydrocarbon traps; 2) by the provision of local structures with deep faults as channels of mantle fluids; 3) by the age of basement formation, which determines the time interval from tectonic activity to the formation of the sedimentary cover; 4) by the level of adjusted gravity difference, which fixes the deconsolidation of certain areas of the sedimentary cover as a factor in improving reservoir properties. Based on the results of the research, the scheme of the Biostromna zone's HC-potential was drawn up. A multi-component analysis of the results of gravimetric studies is proposed, which significantly increases the reliability of selecting priority structures for the search for hydrocarbons from the multitude of objects tracked by seismic exploration.

Published: July 2023

The Osnytsky block is a constituent part of the Osnytsky-Mikashevytsky volcano-plutonic belt. The leading place in the geological structure of the Osnytsky block is occupied by the rock association, which includes a number of plutonic formations from gabbro to leucocratic granites (gabbro-diorite-granodiorite-granite association), formed in the Paleoproterozoic — 1,98—1,95 Ga. The results of lead-lead isotope dating of titanites from diorites, opened by the RPZ-5 quarry, located in the northwestern vicinity of the village Tomashhorod. Diorites were formed in the second phase, after gabroids, before the beginning of the formation of granitoids. The age of 1975 ± 9,1 Ma was obtained for them. The age calculated based on previously published data is 1973 ± 8,3 Ma, which is in good agreement with the U-Pb isotopic age of the zircons of these diorites 1974 ± 1,2 Ma. It was found that to determine the isotopic age of titanites with a high content of ordinary lead, it is enough to use only the isotopic composition of lead, calculating the age in the coordinates of the graph 207Pb/204Pb — 206Pb/204Pb, by the tangent of the angle of inclination of the regression line.
Entanglement Dynamics Induced by a Three-Level Laser Coupled to the Squeezed Vacuum Reservoir
Authors: Alemu M.
Published: July 2023

We have studied the squeezing and entanglement properties of the light induced by a three-level laser coupled to the squeezed vacuum reservoir. Applying the pertinent master equation, we have obtained the evolution equations for the cavity mode variables. Using the solutions of the resulting equations, the squeezing properties, entanglement amplification, and the normalized second-order correlation function of the cavity radiation are described. We have seen that the light generated by a three-level laser is in a squeezed state, and the squeezing occurs in the plus quadrature. In addition, we have also established that the effect of the squeezed parameter increases the mean and variance of the photon number. It is found that the squeezing and entanglement in the two-mode light are directly related. As a result, an increase in the degree of squeezing directly leads to an increase in the degree of entanglement and vice versa. This shows that, whenever there is squeezing in the two-mode light, there exists an entanglement in the system.

Strömungsmechanik zwischen Mathematik und Ingenieurwissenschaft
Authors: Eckert Michael
Published: July 2023

Hydrodynamik galt lange als Fach für Mathematiker und theoretische Physiker. Das Ingenieurfach Hydraulik bietet zwar für viele praktische Probleme brauchbare Formeln an, doch diese konnten nur empirisch begründet werden. Im Wintersemester 1907/08 veranstaltete der Mathematiker Felix Klein an der Universität Göttingen ein Seminar mit dem erklärten Ziel, diese Kluft zu überwinden. Die Beiträge der Teilnehmer zeigen, wie die Kluft zwischen theoretischer Hydrodynamik und praktischer Hydraulik mit der modernen Strömungsmechanik überbrückt wurde.

Purpose - to assess the effectiveness and scope of infusion and transfusion therapy for wounded with penetrating head wounds at the stage of stabilization and preparation for aeromedical evacuation. Materials and methods. A retrospective analysis of the medical records of 122 servicemen who were injured during combat missions was conducted. The Group 1 included 52 servicemen with mine blast thoracoabdominal wounds; the Group 2 - 40 servicemen with penetrating head wounds; the Group 3 - 30 servicemen with combined penetrating head wounds and mine blast thoracoabdominal wounds. The study shows the median and interquartile range of the values of the studied indicators. The Kruskal-Wallis test was used to analyze the data, and a posteriori comparisons were made using the Dunn’s test. Results. A retrospective analysis of the medical records of 122 servicemen who were injured during combat missions was conducted. The total volume of haemotransfusion in the victims of the Group 1 was 1525 (445-2325) ml, in the Group 2 - 0 (0-0) ml, in the Group 3 - 1150 (0-1800) ml. The volume of infusion therapy at the stabilization stage in the Group 1 was 3150 (2450-4200) ml, in the Group 2 - 1200 (800-1400) ml, in the Group 3 - 1400 (880-3200) ml. In the Group 1, the shock index (SI) decreased to 0.67 (0.61-0.71), in the Group 2 - to 0.58 (0.55-0.66), in the Group 3 - to 0.66 (0.61-0.71). The correlation analysis in the Groups 1 and 3 revealed a negative correlation of medium severity between the amount of haemotransfusion and the change in SI (ρ=-0.353 at p=0.01; ρ=-0.525 at p=0.003). Conclusions. Infusion and transfusion therapy in the prescribed volumes allowed to reduce the rate of SI in wounded servicemen by 23.7% (95% CI: 19.2-29.5%). Victims of the Group 3 required a greater volume of infusion and transfusion therapy, which affected the time required to prepare for aeromedical evacuation.

The issue of acute appendicitis remains extremely relevant today, as it is the most common inflammatory disease of the abdominal cavity. Despite significant advances in pediatric surgery in recent decades, when mortality from acute appendicitis is an exceptional event, the number of complicated forms in children is observed in 26.4% of cases, and morphologically unconfirmed appendectomies in 8.8% of cases. In girls, the rates are higher at the age of ≤10 years. Acute appendicitis has been and remains a very common disease in underdeveloped countries. In industrialized countries, the incidence of acute appendicitis ranges from 4-6% to 12-23%, in Ukraine - 20-21 cases per 10 thousand population, mostly young people. Purpose - to state the peculiarities of differentiation of surgical pathology of the abdominal cavity and pelvic organs in girls using ultrasound examination; to develop an algorithm for diagnosing surgical pathology in girls. Materials and methods. The study was conducted on the basis of the at the Vinnytsia Regional Children's Clinical Hospital, National Pirogov Memorial Medical University (Vinnytsia, Ukraine) for the period 2019-2021. For visual differential diagnosis, girls aged 4-16 years were involved in the study: 100 healthy children (the Group 1), 100 children diagnosed with acute phlegmonous appendicitis (the Group 2), 100 children with bulky uterine appendages of various types of pathology (the Group 3). Results and conclusions. The following advantages of ultrasound have been established: high specificity of the study, low cost and absence of ionizing radiation. Ultrasound of the abdominal cavity makes it possible to diagnose acute surgical and gynecological pathology, as well as to carry out differential diagnosis of diseases simulating acute appendicitis. An algorithm for diagnosing surgical pathology in girls has been developed. Such an algorithm increases the effectiveness of ultrasound of acute appendicitis and neoplasms of the pelvic cavity, and this allows the doctor to establish the correct diagnosis in time and choose the appropriate treatment tactics. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of the participating institution.

Útilização do osso úmero para estimativa de sexo: uma revisão integrativa
Authors: De Paiva Gomes Fernandes Eder Akydawan , Adas Saliba Tânia , Martins Schmidt Cristhiane
Published: July 2023

Resumo - Introdução: Estimar o sexo é o primeiro passo para identificação em ossadas humanas, geralmente essa estimativa é realizada em ossos classicamente mais dimórficos como crânio e púbis, porém nem sempre os mesmos estão disponíveis ou estão em condições de serem analisados. Os estudos demonstram que ossos longos do esqueleto são geralmente bem preservados durante os casos forenses e mais fáceis de definir metricamente sendo uma boa alternativa para estimativa sexual. Dentre os ossos longos, o úmero se mostra como um excelente substituto, sua resistência garante que permaneça intacto mesmo com intempéries, sendo possível sua análise mesmo em estado fragmentário. Objetivo: Identificar na literatura os estudo mais recentes que utilizaram o úmero para estimar o sexo. Métodos: Foram utilizados nas principais bases de dados os descritores: Humerus; Sex Characterists; Sex Estimation; Sex Determination Analysis e Sex Characteristics. Após leitura dos artigos, uma tabela de sinóptica foi elaborada com os principais achados dos artigos selecionados. Resultado e Discussão: A maioria dos trabalhos mostraram que o úmero é um osso válido para estimar sexo em diferentes populações, mas fica claro que essas medições devem ser adaptadas para cada amostra individualmente, pois as diferenças físicas e de ancestralidade de determinadas populações impedem a utilização de uma fórmula única universal. Conclusão: O úmero apresentou taxa de sucesso para estimativa sexual superior a 80% em grande parte dos artigos, provando-se uma excelente alternativa na ausência de ossos mais dimórficos.
Processos de Classificação e de Categorização da Diversidade Cultural e Migratória das Populações no Contexto Europeu
Authors: Cândido Ana , Seabra Teresa
Published: July 2023

O debate em torno da classificação e da categorização da diversidade cultural e migratória das populações que vivem no espaço europeu tornou-se mais relevante e complexificou-se na presente década. Este debate é marcado por falta de consenso sobre que indicadores devem ser recolhidos para caracterizar a origem das populações. A falta de orientações específicas e as diferentes formas de classificação contribuem para uma heterogeneidade de categorias utilizadas para caracterizar a origem das populações, concebendo-se diferentes formas de ler e observar a realidade da diversidade cultural e migratória em cada país. Neste quadro, o principal objetivo deste documento de trabalho é proceder ao levantamento dos processos de classificação e de categorização da diversidade cultural e migratória das populações, em curso nos países europeus. O texto está organizado em três secções. Na primeira analisam-se os indicadores recolhidos nas estatísticas oficiais (censos) dos países europeus para classificar e categorizar a origem das populações. Na segunda alarga-se a análise aos modelos de classificação e de categorização das populações de origem imigrante utilizados na produção de conhecimento científico. Por último, considerando que todos estes processos analíticos transportam desafios, dilemas e problemas, sintetizam-se os principais problemas presentes nos esquemas de classificação e de categorização, organizados em quatro dimensões: (i) os problemas político-jurídicos; (ii) os problemas de reducionismo; (iii) os problemas de comparabilidade; e (iv) o problema da exterioridade.

Published: July 2023

This article presents the results of an expert survey aimed at identifying competencies that are significant for the career self-determination of young people in the digital environment as a psycho-reflexive activity aimed at finding their own way of building a career and creating its image. Teachers and students of Pskov State University (n = 120) acted as experts. The expert survey was conducted in two stages. At the first stage, each respondent had to make a list of 5 indicators that are significant for career self-determination in the digital environment. As a result, a general list was formed, including 23 items. At the second stage of the expert survey, the respondents were asked to evaluate the significance of each indicator for career self-determination. As a result of the survey and factorization of the data obtained, six complex competencies were identified: special IT competencies, general user IT competencies, general career-relevant personal competencies, special career-relevant competencies, competencies in the field of internal analysis, competencies in the field of external analysis. At the same time, in the ranking of these competencies, personal indicators come first, and competencies in the field of IT technologies are in the closing position. It was also found that the key indicators for career self-determination of young people in the digital environment are a sense of humor, strong-willed qualities (persistence, purposefulness, initiative), the ability to quickly search for information, communicative competence and creativity. At the same time, students, unlike teachers, emphasize the great importance of acting abilities, a sense of humor and the level of general erudition for career self-determination in the digital environment.
Dynamics of causes and factors of obtaining secondary vocational education: the situation of «college at the university»
Authors: Karpikova Irina , Khitrova Elena
Published: July 2023

The article is devoted to the results of a sociological study of the causes and factors determining the educational trajectories of students of secondary vocational education. The trend of recent years in the field of vocational education has been a gradual increase in the number of school graduates entering secondary vocational education institutions, while at the same time reducing the number of graduates entering higher education programs. The above explains the relevance of studying the dynamics of the structure of causes and factors that determine professional and educational trajectories. The authors also substantiate the need to take into account the factors associated with conducting such studies of the characteristics of a particular category of secondary vocational education institutions, one of which includes colleges at universities. The authors conducted two rounds of a questionnaire survey in 2018 and 2023 of senior students of all specialties of the Baikal State University College. The monitoring nature of the survey made it possible to consider the dynamics of the structure of the reasons and factors of admission to the «ollege at the university» and to determine changes in the preferred professional and educational trajectories of students after they receive secondary vocational education. There are significant differences in the studied issues between students studying on the basis of basic and secondary general education. In general, there is a general decrease in the importance of the factor of the possibility of entering a university without passing a unified state exam after graduation from college. For students on the basis of 9th grades, the importance of factors related to the possibility of obtaining a profession and a workplace more quickly has increased. The analysis of the dynamics of educational intentions revealed a significant decrease in interest in further education at the university both in the near and long term, which is especially pronounced among those enrolled in college on the basis of basic general education. In general, the data obtained confirm the general trend of strengthening the importance of secondary vocational education as an independent educational level.

Natural kaolinite obtained from Share, Nigeria was treated with ammonium carbonate to enhance the adsorption capacity. The optimum operating conditions for the adsorption of metal ions on the natural clay (SK clay) were employed on the ammonium carbonate-treated clay (SK-AC clay). The adsorption data were analysed using adsorption isotherm and kinetic models. The statistical p-values were less than 0.05, indicating that the model terms are significant for the adsorption of the metal ions. The pseudo-second-order kinetic model best describes the metal ions adsorption mechanism. The activation energy values less than 40 kJ mol-1 obtained indicated physisorption. Langmuir adsorption isotherm model fitted the adsorption data for Fe2+, Zn2+ and Cr6+ ions while the Freundlich model fitted Pb2+ ions adsorption. Analysis of thermodynamic parameters shows the adsorption is spontaneous and endothermic. The ammonium carbonate-modified clay exhibited an increase in adsorption capacity from 10.74 to 13.60 mg g-1, 16.48 to 17.38 mg g-1 and 11. 96 to 13.8 mg g-1 for Fe2+, Pb2+ and Zn2+ ions while uptake of Cr6+ decreased from 8.75 to 7.25 mg g-1. The results showed that the adsorption of Fe2+, Pb2+ and Zn2+ ions onto kaolin-containing cowlesite can be enhanced by treating it with ammonium carbonate.

The South African grade 9 Natural Sciences curriculum suggests the use of everyday science to introduce the usefulness and the relatability of science to learners. Many learners, however, seem to have a negative attitude towards science learning and science as an entity. This study is an intervention that sought to ascertain the attitudes of grade 8 and 9 learners in under-resourced schools in South Africa after they had carried out kitchen chemistry hands-on practical activities at science clubs in under-resourced township schools. The learners were interviewed about their experiences, and university student volunteers at the science clubs were also interviewed. An inductive-deductive thematic approach was used to analyse the qualitative interview data. The findings of the study revealed that the learners had a more positive attitude toward science after they had been engaged in the kitchen chemistry hands-on practical activities. Additionally, the integration of everyday knowledge promoted conceptual understanding and improved the performance of the learners. The interviews with the student volunteers revealed aspects that they thought would improve learners' attitudes to science. Science clubs run by university student volunteers could assist in promoting a positive attitude to science among learners.

Предложено решение задачи оптимального проектирования электромагнитов левитации разработанным методом решения обратных задач. На его основе в программной среде Octave на языке Lua создан комплекс программ для проектирования п-образного электромагнита с двумя управляющими катушками. Сокращение времени решения обратных задач достигнуто преобразованием ограничений в целевые функции и последовательной минимизацией этих функций по ограниченному числу переменных. Комплекс программ позволяет определить начальные приближения искомых параметров аналитическим решением обратных задач на основе моделей эквивалентных магнитных цепей, вызвать пакет FEMM для численного решения прямой краевой задачи расчета плоскопараллельного магнитного поля и силы левитации, выполнить минимизацию функционалов задачи, найти искомые параметры при выполнении заданных ограничений. Разработанный метод и комплекс программ могут быть использованы для проектирования различных электротехнических устройств.

Рассмотрены теоретические аспекты применения асинхронных электродвигателей серии ДАТ (ДАО) в промышленных приводах с частотным преобразователем: принципиальная схема, Т-образная схема замещения и механические характеристики тягового электропривода в диапазоне 40…120 Гц. Проведены экспериментальные исследования значений виброскорости (частотный диапазон 10…1000 Гц), виброускорения (частотный диапазон 10…10000 Гц) в контрольных точках корпуса статора при изменении частоты питания в диапазоне 60…120 Гц и соответственно частоты вращения 1800…3600 об/мин. При обработке данных использованы аппарат спектрального состава и анализ временных реализаций вибрационного сигнала. Выявлена неравномерность вибрационных и тепловых полей. Полученные диагностические признаки нарушения равномерности воздушного зазора и магнитных полей могут служить основанием для проверки электрической части двигателя на испытательном стенде.
A Sociologia como disciplina escolar no Brasil: uma leitura a partir das reformas educacionais
Authors: Dos Reis Neuhold Roberta
Published: July 2023

Este artigo recupera alguns marcos legais do processo de inclusão e exclusão da Sociologia no ensino médio brasileiro para analisar sua história enquanto disciplina escolar. Inicialmente, dialoga com estudos da história da educação para sugerir que os conflitos em torno da introdução e permanência da Sociologia no currículo exemplificam as relações e embates entre o campo científico e escolar, de um lado, e a esfera política, de outro. Em seguida, a partir de um esforço de revisão bibliográfica e de uma pesquisa documental cuja principal fonte é a legislação educacional, prossegue com a periodização da Sociologia no currículo, desde 1890 até 2017.

This study aims to investigate the relationship between primary school administrators' technological leadership self-efficacy and 21st century skills. Employing descriptive (survey) research method, the opinions of the primary school administrators working in the state primary schools in the districts of Konya were examined. The Education Administrators Technological Leadership Self-Efficacy Scale and the 21st Century Skills and Competences Scale Directed at Teaching Candidates were administered. In order to analyse the data collected in the study, in which 272 questionnaire responses were collected, arithmetic mean, standard deviation, percentage, t-test, one-way analysis of variance (ANOVA) and correlation test and Cohen's d test were performed. The results revealed that primary school administrators' perceptions of technological leadership self-efficacy turned out to be at adequate level. It was also seen that there was no significant difference in terms of technological leadership levels of administrators in line with gender and professional experience. It was seen that school administrators' consider 21st century skills important. The results also indicated that there was no significant difference between primary school administrators' perception of 21st century skills and gender, experience, and age. In addition, there is a significant difference between primary school administrators' perceptions of 21st century skills and the variables of position and educational status. The findings also showed that there is a positive, moderate, and significant relationship between the sum and dimensions of primary school administrators' technological leadership behaviours and the sum and dimensions of 21st century skills.

Authors:   HSE University, Zolotareva Alena A.
Published: July 2023

During the COVID-19 pandemic, researchers recorded the growth of cyberchondria as a tendency to excessive and repetitive search on the Internet for information about the symptoms of various diseases. The objective of this study was to adapt the Russian version of the Cyberchondria Severity Scale-12 (CSS-12). It measures the structure of cyberchondria: compulsion, i.e. searching online interrupts daily activities; distress, i.e. the negative emotional consequences of the search behavior; excessiveness, i.e. repeated health-related research that may escalate search behavior; reassurance, i.e. desire to consult with a health care provider after searching online (McElroy, Shevlin, 2014). The crosssectional study involved 624 respondents who completed the Russian-language versions of the CSS-12 and the Symptom Check List-90-Revised (SCL90-R). The confirmatory factor analysis revealed the bifactor structure of the Russian CSS-12, suggesting both the general factor of cyberchondria and specific factors of excessiveness, distress, reassurance, and compulsion. The Russian CSS-12 demonstrated high internal reliability with an α-Cronbach coefficient of 0.95 for the total score. The convergent validity of the Russian CSS-12 was confirmed through its positive correlations with the SCL-90-R scores. Results of the sociodemographic analysis showed that cyberchondria was not associated with gender, but excessiveness, distress, reassurance, compulsions, and total CSS-12 score were negatively associated with age. The findings showed that the Russian CSS-12 is a reliable and valid instrument for population-based research of cyberchondria and needs further psychometric examination on various clinical samples.

Our study is dedicated to the development and the psychometric properties evaluation of the short Russian version of Barratt Impulsiveness Scale (BIS11). The sample included 303 healthy young adults: 116 (38.28%) women and 187 (61.72%) men. The mean age was 23.22 (SD = 3.28) years. Exploratory and confirmatory factor analyses, reliability assessment (McDonald’s omega (ω) and Greatest Lower Bound (GLB)), correlation analysis (between subscales of the inventory), gender differences analysis (U Mann–Whitney) were conducted. Additionally, we proposed normative intervals. The short 3-factor version consisted of 14 items, and the total score as a second-order factor was obtained (2 = 151.647; df = 76; CFI = .914; TLI = = .896; RMSEA = .057; SRMR = .075). According to the factors' items, subscales were named “Motor Impulsive ness”, “Attentional Impulsiveness”, “Non-Planning Impulsiveness”, which is close to the original version. The scales shown satisfactory reliability level (ω/GLB): Total Score — .724/.843; Motor Impulsiveness — .713/.715; Attentional Impulsiveness — .712/.773; Non-Planning Impulsiveness — .636/ .685. Gender differences were found on the Total Score and on the Motor Impulsiveness scale. Hence, we've received the model of the Russian version of Barratt Impulsiveness Scale with good psychometric properties. The text of the questionnaire, scoring, and norms are provided in the appendix. However, to confirm this version, additional research is required.
