Метакогнитивные стратегии в текстовой деятельности (на примере англоязычных научных текстов)

Globalization on the one hand and border closure on the other hand spur communication process participants in all areas of human activities and especially young researchers into foreign language learning which is currently focused on foreign professionally-oriented texts. Traditional methods of teaching a foreign language based on grammatical approach are not effective in solving the problem of language competence development when working with professionally-oriented texts. The objective of this work is to assess the effectiveness of the method of legal texts concept analysis using a technique of metacognitive strategies in reading activity. Several groups of law students, Southwest State University (Kursk, Russia) took part in the experiment based on the above-mentioned method. Students performed both conventional (skimming, key words finding) and specially developed tasks (constructing a text compositional structure model, plotting a text graphical representation, etc.). Original criteria were used to evaluate the performance. The experiment showed a persistent significant difference in learning indicators and students’ behaviour in the control and experimental groups. The technique contributed to the development and enhancement of students’ skills improving their foreign language competence. The obtained skills facilitated communication and contributed to students’ satisfaction with the learning process, increased their creative and professional potential, students’ sustainable intrinsic motivation.

Using Fuzzy Mathematical Model in the Differential Diagnosis of Pancreatic Lesions Using Ultrasonography and Echographic Texture Analysis.

Malignant tumors of the pancreas are the fourth leading cause of cancer-related deaths. This is mainly because they are often diagnosed at a late stage. One of the challenges in diagnosing focal lesions in the pancreas is the difficulty in distinguishing them from other conditions due to the unique location and anatomy of the organ, as well as the similarity in their ultrasound characteristics. One of the most sensitive imaging modalities of the pancreas is endoscopic ultrasonography. However, clinicians recognize that EUS is a difficult and highly operator-dependent method, while its results are highly dependent on the experience of the investigator. Hybrid technologies based on artificial intelligence methods can improve the accuracy and objectify the results of endosonographic diagnostics. Endoscopic ultrasonography was performed on 272 patients with focal lesions of the pancreatobiliary zone, who had been treated in the surgical section of the Kursk Regional Clinical Hospital in 2014-2023. The study utilized an Olympus EVIS EXERA II video information endoscopic system, along with an EU-ME1 ultrasound unit equipped with GF UM160 and GF UC140P-AL5 echo endoscopes. Out of the focal formations in the pancreatobiliary zone, pancreatic cancer was detected in 109 patients, accounting for 40.1% of the cases. Additionally, 40 patients (14.7%) were diagnosed with local forms of chronic pancreatitis. The reference sonograms displayed distinguishable focal pancreatic pathologies, leading to the development of hybrid fuzzy mathematical decision-making rules at the South-West State University in Kursk, Russian Federation. This research resulted in the creation of a fuzzy hybrid model for the differential diagnosis of chronic focal pancreatitis and pancreatic cancer. Endoscopic ultrasonography, combined with hybrid fuzzy logic methodology, has made it possible to create a model for differentiating between chronic focal pancreatitis and pancreatic ductal adenocarcinoma. Statistical testing on control samples has shown that the diagnostic model, based on reference endosonograms of the echographic texture of pancreatic focal pathology, has a confidence level of 0.6 for the desired diagnosis. By incorporating additional information about the contours of focal formations obtained through endosonography, the reliability of the diagnosis can be increased to 0.9. This level of reliability is considered acceptable in clinical practice and allows for the use of the developed model, even with data that is not well-structured.

Linguodidactic Testing in the Digital Environment as a Tool for Teaching and Controlling the Formation of Language Competence of Foreign Speakers

The article analyzes the system of test tasks in Russian as a foreign language at the stage of pre-university training, designed to control the language competence of students.The aim of the study is to provide high-quality test technologies that contribute to the formation of language competencies of foreign speakers in the conditions of distance and blended learning formats, to analyze their effec-tiveness in study monitoring, self-control and corrective measures.The test materials and the results of the current, interim and final test control in Russian as a foreign language serve as the material of the study. The test materials were created by the authors on the Moodle platform for teaching foreign citizens at the stage of pre-university training at Southwest State University and were uploaded to SWSU’s electronic information educational environment.The Moodle platform has a wide range of tools for designing test tasks, statistical processing of test results, which allow teachers to get information about the quality of tests.The authors of the study conducted a selective statistical analysis of the tests for the current, interim and final control, followed by the adjustment of certain test questions. Statistical analysis took into account such parameters as ease index, standard deviation, random guess score, target weight, effective weight, discrimination index, discrimina-tion efficiency.Automated control at the initial stage of learning Russian as a foreign language is systematic and regular and makes it possible to check the knowledge and skills in vocabulary and grammar acquired in the process of learning, allows the teachers to objectively evaluate and compare the successes and shortcomings in the educational activities of foreign stu-dents, to identify the level of language proficiency, excluding the teacher’s subjective opinion of the student and provides for the possibility of feedback, significantly reduces the time spent on checking and analyzing the results.The authors came to the conclusion that the analyzed tests optimize the learning process and objectify control, give students the opportunity of self-control and teachers the opportunity of varying ways to control and manage stu-dents’ independent learning activity.

The Experimental Study of the Image of Russian Color Term Blue in the Consciousness of Russian Culture Bearers

The article is devoted to the study of the color term blue. This color occupies an important place in the color picture of the world of representatives of Russian culture, which determines the relevance of the empirical study of the image of this color term from the point of view of psycholinguistics. The theoretical basis of the study was the work of A.A. Zalevskaya, A.P. Vasilevich, E.I. Goroshko.When organizing and conducting the research, we assumed that individual and cultural knowledge about color are united in the linguistic consciousness. So, any image in the consciousness of an individual has its cultural and personal component. The main methods used in the work are associative experiment, semantic differential, factorial and definitional analyses. We used the data from related sciences in the process of analyzing the results of the study. The study was conducted on the basis of Southwest State University among full-time and part-time students.The work shows the structure of the associative field of the color term blue in different time periods, which al-lows us to clearly demonstrate the dynamics of changes in this field over the past thirty years.The article also examines the gender structure of the associative field of the color term blue, highlights general gender-neutral associations, as well as associations that are typically female or typically male. In addition, a factor analysis of the results of the semantic differential is carried out from the point of view of the gender characteristics of the perception of color term blue.The methodology of organizing and conducting experimental research described in the paper can be success-fully used for psycholinguistic research of images of various stimulus words. The data obtained during the experiment can be used not only in linguistics, but also in marketing, psychology and advertising.

Aspects of implementation of models of interaction between career centers of universities and industrial enterprises in the conditions of labor market transformation

Today universities are creating all conditions for successful training, improving the graduates’ competitiveness at the labour market and employment according to the qualification received. In the conditions of social and economic transformations a significant number of young specialists are not able to adapt to the labor market. This is caused by lack of practical experience and the resulting low professional status. The balance between the labor market needs for young specialists and the universities’ ability to educate them can be achieved by close interaction between the professional educational institutions and potential employers. To coordinate the interests of both experts apply various interaction models able to ensure harmonization of the process.The article in hand deals with four models of interaction between the university career centres and partner companies which use two models of such interaction in the Southwest State University. The authors analyzed the level of integration of the career centres with other structural departments of the university showing the link between the interaction model implemented in the university and the level of integration. The research allowed to make a conclusion about sufficient influence the university career centres’ activities on the graduates’ competitiveness at the labour market.Cooperation of universities and employers is aimed at implementing a complex of measures, means and methods which ensure providing the appropriate level of professional education. Also it contributes to solving the following tasks: engagement of the companies in the graduates’ employment according to their qualifications, participation of the university staff in scientific research activity within the topics suggested by the companies, involvement of the partner companies to career guidance activities and events aimed at developing the information environment in the labour market and increasing the attractiveness of the employer’s brand in the eyes of graduates.Regional universities are facing the problem of the graduates’ employment in the city – forming enterprises and companies operating in the region. Taking into account that young specialists tend to migrate to the regional centres, it is essential to take measures to increase the attractiveness of work conditions with the emerging trend of staff outflow. Promotion of employment of young specialists can be effective only in case of establishing long-term “university-student-employer” partnership.

Main results of experimental studies of reinforced concrete structures of high-strength concrete B100 round and circular cross sections in torsion with bending

Aim of the research to verify the proposed calculating apparatus and accumulate new experimental data on the complex resistance of reinforced concrete structures, experimental studies of such structures made of high-strength concrete of circular and circular cross-section were conducted at the testing base of the South-West State University. Method is experimental-theoretical. Results of experimental research the plots of the deflections and rotation angles, the dependency of deformations of concrete according to the testimony of the outlets of electrodesorption with respect to the calculated cross section 1-1. The main deformations of elongation and shortening of concrete were determined; the reinforcement was selected in such a way that in the stage preceding the destruction, it reached fluidity, so the stresses in the reinforcement are known. It is established that for reinforced concrete structures made of high-strength concrete of circular cross-section, as a rule, there is the development of two cracks, i.e. the round shape of the cross-section slightly reduces the concentration due to the structure of high-strength concrete. For the annular section there were several cracks, of which stands out the one on which the destruction occurs. On the steps preceding the destruction, this crack begins to prevail over the rest and has a maximum opening width. On the basis of experimental studies of reinforced concrete structures made of high-strength concrete of square and box sections, reliable data on the complex stress-strain state in the studied areas of resistance, such as: the values of the generalized load of cracking , and destruction ,, its level relative to the limit load; the distance between the cracks at different levels of cracking (up to the moment of destruction, as a rule, two or three levels are formed); crack widths at the level of the axis of the working armature, at a distance of two diameters from the axes of the armature and along the entire crack profile at various stages of loading, from which it follows that the crack opening at the level of the axis of reinforcement in 2-3 times less compared with the crack opening on the removal of 1.5-2 diameters of the working axis (longitudinal and transverse) reinforcement; the coordinates of the spatial formation of cracks; schematic drawings on tablets of education, development and opening of cracks of reinforced concrete constructions in torsion with bending. Thus, the experimental studies and the result provide an opportunity to test the developed computational model and its working hypotheses for assessing the resistance of reinforced concrete structures made of high-strength concrete in torsion with bending.

Increasing indicators of effectiveness of the higher educational institution by regulation of the threshold scores of the unified state examination

The paper describes improving the efficiency of educational activities of higher education institutions on the example of enrollment to the South-west state university in 2015-2017. The main efficiency criterion of educational activity is grade-point average evaluation of persons accepted for full-time study. This criterion is set by the Ministry of Science and High Education of the Russian Federation. It is shown on the example of statistical data of the unified state examination in Kursk region in 2015-2018. The implementation of this criterion is determined by admission structure of higher education institutions (the list of specialties, entrance tests, state-funded places). Increasing of grade-point average is possible by threshold scores increasing for one or several subjects (entrance tests). The analysis shows that such approach allows GPA increasing of enrolled students but at the same time leads to income decrease of the educational organization due to the reduction of accepted students. There are diagrams that show dependence of GPA from threshold score change of such subjects as Russian language, Mathematics and other subjects. The diagrams also show income decline at increase in threshold scores in specified cases. GPA increase of the unified state examination by changing the threshold score is economically inappropriate as it influences other efficiency indicators (assessment of financial and economic activity, average salaries).
