Bioclimatic design as a large city urban structure reorganization factor
Authors: Zharkova Maria , Paramonova Oksana , Yudina Natalia
Published: June 2021

The modern landscape of a large city is a complex, dynamically changing environment with a constant influence of environmental, social and economic factors. The gradual historical development of the territory and the change in urban processes led to the formation of a city containing mixed-type areas, i.e. border territories and separate zones - industrial, residential, intermediate. In Russia, the improvement of coastal zones in large cities has become an urgent task when adjusting master plans for the development of territories [1-5]. The main component of such projects is the development of a concept for the renovation of coastal zones into generally accessible natural and recreational recreation areas based on water bodies within the urban planning. The creation of recreations, recreation areas, the formation of a system of pedestrian communications, the opening of residential complexes to the water, the integration of water into public urban spaces [2-6]. A comprehensive analysis of theoretical studies and design experience made it possible to highlight the properties of water used in architecture and urban planning. Thus, the development of a promising bioclimatic model of urban settlements of the third millennium will be based on ecological design, which includes part of the processes of the circulation of substances and energy, as well as harmony in the environment [6-9].

Published: June 2021

The dehydration parameters (temperature, thickness, and mass load) statistically significantly (p<0.05) affect the thin-layer convective dehydration of potato slices. The slices with thicknesses of 3, 5, and 8 mm were dehydrated as monolayers at different temperatures (30, 50, and 70 °C) and mass load (1.00, 0.63, and 0.38 kg m-2). The results showed that the shortest dehydration time (183 minutes), the smallest energy consumption (0.176 kWh), and the smallest emission of carbon dioxide (0.17 kg) had the dehydration model of potato slices with a 3 mm thickness, 0.38 kg m-2 mass load, dehydrated on the temperature of 70 °C. Dehydration of potato slices of 8 mm slice thickness dehydrated at 70 °C, with 0.38 kg m-2 mass load, showed the highest resistance to mass transfer (the maximum effective moisture diffusivity 2.3761 × 10-7 ± 4.45646 × 10-9 m2 s−1) and the minimum activation energy (27.02 kJ mol-1). Data obtained from these mathematical models could predict and optimize the thin layer dehydration of potato slices, with a dominant influence of temperature and potato slice thickness parameters as variables.

Mortgage and mortgage lending as a tool for financial recovery of the modern Russian economy
Authors: Rybak Svetlana
Published: June 2021

The article is devoted to the institutional analysis of the problem of improving the legal regulation of mortgage relations in Russia in modern conditions in the presence of a rather limited financial capacity of the population in modern conditions to purchase real estate or housing. In this regard, the mortgage becomes the most necessary tool to ensure the socio-economic development of society, its stable and sustainable development. The formation of the property base currently generates a corresponding demand in the real estate market, and develops a corresponding interest among consumers in mortgage lending. At the same time, the emerging financial mechanism of mortgages also ensures the formation of the solvency of not only the population, but also other market participants, so that this market segment becomes not only in demand, but also successfully developed. Considering this problem, the author sought to update the scientific, theoretical and practical interest in this topic and to reveal the problems that hinder the development of mortgages as an important factor in the financial recovery of the modern market economy.
Ideas about difficult situations and other people among students with social frustrations
Authors: Alperovich Valeriya , Korochentseva Anna
Published: June 2021

The article describes the problem of psychosocial personal characteristics as predictors of the coping behavior. Over the past few decades, the world has changed beyond recognition, the current generation of students has changed, and therefore the strategies that they use to cope with the difficulties that have appeared in their lives have also changed. The ways of their adaptation to modern reality have changed in comparison with the older generation. In this regard, the study of various predictors of coping behavior, which today prevail in the modern student environment, becomes relevant. The authors used content-analysis of metaphors, tests and methods of mathematical statistics (quartiles, regression analysis, Kruskal-Wallis H-test) and discovered the dependence between social frustration, metaphors of difficult life situations and coping-strategies. So, a high level of social frustration is connected with low rational and adaptive coping strategies in difficult life situations. Various coping strategies are associated with different metaphors of difficult life situations and of their participants: “friends” and “aliens”. The metaphors reflect personal perception of these situations based on scales “short distance-long distance”, “rational value-emotional value” and on parameters “undertaking the responsibility – placing the responsibility with others”, “stereotypical or differentiated image of the situation”.

Application of information technologies for the development of communication skills
Authors: Golovina Аlfina , Feofanov Vasily
Published: June 2021

The goals of modern preschool education imply the creation of conditions for promoting the development of the child's personality, including his communication skills. Their lack of development creates barriers in the process of relationships between preschoolers with peers and adults, and can also lead to problems of self-development, social maladjustment and personal isolation. In children with disabilities, persistent violations of all components of the communication process are observed, which manifest themselves in a decrease in the communicative and cognitive need for interaction with peers and adults. They acquire many skills, including communication, much later, compared to a normally developing peer. In this regard, the need for purposeful development of communication skills in preschoolers with disabilities is becoming increasingly clear. The research methods used were "Observation of the manifestations of communicative abilities in preschoolers" (A.M. Shchetinina, M. A. Nikiforova), the sociometric method "Two Houses" (T. D. Marcinkovskaya), "Diagnostics of the child's communicative abilities "Plot pictures" (N. E. Verax), "Plot pictures" (R. R. Kalinina), "Observation of the manifestation of independence" (A.M. Shchetinina). The data was processed using the Statistica 6.0 software package and the Mann–Whitney U-test and Wilcoxon signed-rank test. Based on the data obtained, it can be concluded that the hypotheses that children of older preschool age with disabilities who attend a group of combined orientation have disorders in the development of communication skills, as well as a correctional and developmental program based on the method of fairy-tale therapy, can overcome the existing communication disorders in preschoolers with disabilities. As evidenced by the results obtained using the methods of mathematical statistics.
The dynamic specificity of interlingual interference within the context of virtual space: towards the theoretical framework of the phenomenon (by the example of political discourse)
Authors: Nikolaev Sergey , Sarkisov Emil
Published: June 2021

This paper deals with the problem of interference within the context of language convergence in virtual space. The study aims to analyze in detail the role of virtual space communication as a new favorable environment for interferential processes not just on the structural level, on the conceptual level too, since deviation from language norms as a serving instrument in terms of formation of the linguistic picture of the world results in changing the way one conceptualizes reality. The major research methods are contrastive analysis and conceptual analysis. The practical significance of the research is determined by the fact that its results can be used in the educational process, for example, when teaching various courses in intercultural communication, political psychology, sociology, cultural and contact linguistics, (foreign) language teaching, cross-cultural pragmatics, etc. The authors come to a conclusion that significant modifications on the conceptual level occur due to language contacts intensification and because of a stable interference pattern in speech and affect communicants’ behavior. This in turn leads to conceptual transformation in language and, as a result, in the way of thinking. The most significant manifestation of this phenomenon can be seen in the political life of the society.

Published: June 2021

The purpose of the study is to analyze the experience in organizing the learning process at a university using digital technologies, aimed at realizing the content of pedagogical education in the context of its structural components and indicators of students’ readiness to work in an educational institution. The positive and negative aspects of the use of IT- technologies in the formation of the experience of professional and pedagogical activities of students in the direction of “Pedagogical education” are noted. The relevance of using digital technologies in the educational process is dictated by the prevailing socio-cultural conditions, the development of information and communication means of transmission and information. At the same time, the problem is the unwillingness of the faculty, students, to their use for several reasons: news, illiteracy, lack of equipment in detail-spatial environment of technical means, the quality of Internet connection. And technologies which provide ability to save dialogicality pedagogical culture, allowing to establish a dialogue in the systems “teacher-student”, “student-teacher” and the polylogue “student-teacher-students” are particularly in demand. The use of the technology “Immersion in professional and pedagogical activity through culture with the support of the teacher” allows the teacher to conduct a dialogue with students and purposefully form their readiness for pedagogical activity in modern conditions based on the acceptance of the values of pedagogical culture and identification in her, personal and semantic attitude to labor functions for the provision of educational services for the main educational programs of educational organizations of different levels.

Authors: Abashina Natalia , Berdnikova Natalia
Published: June 2021

The article discusses the psychological and pedagogical approach to accompanying young children with delayed speech development (delay in speech development manifests itself in a slower pace of mastering native speech by children under three years of age, underdevelopment of the vocabulary, lack of formation of expressive speech, lack of phrasal and coherent speech etc.). The purpose of the study is to develop a program of psychological and pedagogical support for young children with delayed speech development. During the testing of the program, special attention was paid to the processes of development of fine, general and articulatory motor skills of young children in various types of activity (play, cognitive, productive, communicative, etc.); the formation of mental processes (perception, thinking, memory, etc.); speech development of children (understanding of an adult’s speech, development of auditory perception, correction of sound pronunciation, formation of a passive vocabulary, an increase in the volume of an active vocabulary, development of coherent speech, grammatical structure of speech, etc.); interaction of specialists and parents of young children (teacher-psychologist, speech therapist, teachers, educators, medical personnel, etc.) using offline and online technologies (consultations, workshops, seminars, open classes, etc.). As a result of approbation of the program in young children with delayed speech development, there were positive changes in the formation of speech and non-speech functions (understanding of the speech of others, the formation of a dialogue form of speech, the development of the motor sphere, etc.).
The role of real humanism in the digitalization of schools: methodological aspects
Authors: Eroshenko Tatyana , Melnik Anastasia
Published: June 2021

The introduction of digitalization in the educational space causes anambiguous reaction. Some consider it a tool for solving the problems accumulated in school, while others openly define it as a factor in the school dehumanization. In order to understand what digitalization brings to the schools, you need to know the goal of implementing it. The author believes that in the broadest sense school and society form a single whole. In connection with the rapid update of technologies in the production and non-production spheres, there is a need to add managerial relations in the labor sphere with pedagogical ones. Complicated out-of-school conditions for younger generationeducation force the school itself to work more closely in synergy with society, and for this a democratic public schoolmust exist. A school that uses the “digitalization of the educational space” tool will have to implement the function of connecting with the past, determining its place in the present and future. Consequently, the school also performs the function of spiritual confrontation in hybrid wars. Skilful use of the “digitalization of the educational space” will create conditions in which the school can be useful for production and vice versa. The role of school in interaction with society is increasing due to the transformation of the cognition process into the main type of human activity. The tool of digitalization should be used in the environmental education and the entire society, since ecology currently includes all the pressing problems of humanity.
Metaconvergence as a methodological strategy of education in information culture
Authors: Andreeva Olga , Eldarion Artur
Published: June 2021

The aim of the study is to formulate a methodological education strategy that is adequate to the modern socio-cultural situation, which will allow, when using the achievements of digital technologies, to maintain the humanistic dimension of the student’s consciousness. The scientific novelty of the research lies in the proposed methodological educational strategy – meta convergence. Metaconvergence is a way of realizing an educational co-being that initiates the reproduction of cultural matrices in the “sphere of one’s own” subject of education. Metaconvergence, forming the ontological prerequisites of knowledge, makes it possible to organize pedagogical communication in a special way, which is capable of synthesizing educational, personal and cultural dimensions into a single tissue. The research methods were phenomenological and systemic approaches. The phenomenological method made it possible to structure the problem of the methodology of education in the context of the premiselessness, as well as to thematize education in terms of the ability to form meaning within the boundaries of the subject knowledge. The use of the procedures of the systemic method made it possible to build the realizable tasks of the educational process into a system, the core of which is the concept of metaconvergence as a methodological educational strategy. As a result the use of the declared methodological educational strategy, educational tasks of the humanitarian, communicative, motivational and axiological spectrum are solved. It is shown that meta convergence makes it possible to overcome the boundaries of disciplinary paradigms and to approve the need for a humanitarian attitude at an interdisciplinary level.

Published: June 2021

Today, both in science and in everyday life, there is an increased interest in the concept of the human body. For a modern person, his body becomes that essential condition that largely determines professional, social and even personal success. It can even be said that the concept of the body is today one of the aspects of the social concept of a person and his place in society. Indeed, there is a clear trend towards an increase in the consumption of services aimed at meeting the need for the formation of a healthy and beautiful body: sports clubs and gyms, home exercise equipment, diet food, body shaping services in a variety of ways, etc. The conducted research has shown that despite the elaboration of the question of self-physical in theoretical terms, there is a certain lack of research in this area with a practical focus. Today, in state policy, the priority is to orient the population towards a healthy lifestyle. Consequently, for psychologists, the targeting of psychotherapy methods should be to help people with different attitudes to a healthy lifestyle. In order for such recommendations to be really useful and scientifically substantiated, it is advisable to identify significant differences in the understanding of the physical self by people with different attitudes towards a healthy lifestyle.
The discrediting strategy in the pre-election political discourse (based on the example of debates between Donald Trump and Joe Biden)
Authors: Abdurakhmanova Diana , Redkozubova Ekaterina
Published: June 2021

Speech manipulation in the pre-election discourse aims to influence the audience in order to increase the number of the electorate and present their political activities in a more favorable way. This article is devoted to the study of ways to achieve this goal using strategies of self-presentation and discrediting. It is known that the political struggle for power at the stage of debate is carried out mainly through a strategy of discrediting. The task of belittling the opponent's status comes to the fore. Such activity involves a set of certain tactics that help to implement it: from the most common tactics of accusation and ridicule to less frequent tactics of exaggeration and unproven undermining of authority. This analysis demonstrates the variety of tactics used by Donald Trump and Joe Biden in the 2020 political debate as part of a discrediting strategy. The result of the study showed that politicians resort more to tactics of open speech influence, which takes place in offhand speech. In addition, the efficiency of the strategy of discrediting in political discourse was revealed.

Authors: Ignatova Svetlana , Bobykina Irina , RKoleeva Elmira
Published: June 2021

The article reveals the influence of extracurricular projects in a foreign language on the students’ motivation in non-linguistic areas of university education for learning a foreign language. Extracurricular projects include Olympiads, conferences and various competitions for translation, essays, videos and similar types of extracurricular activities. The article reveals the illumination of the problem of motivation in the psychological and pedagogical community and gives various points of view on the factors that contribute to increasing motivation for learning a foreign language through extracurricular projects. A survey of students with non-linguistic specialization of the university revealed the key positive and negative factors that determine the attitude of students to such projects. The insignificant number of project participants is explained by the lack of awareness among students and fear of failure. The factors encouraging participation were the interest in the format of the event, the expected benefits for professional development, the support of the environment and a sense of belonging to the faculty. On the basis of the results obtained, recommendations are given to increase the motivation of students to learn a foreign language through participation in projects in foreign languages, and the need to integrate extracurricular academic activity into the educational program is substantiated.

Authors: Luchinskaya Elena , Volkova Rosa , Kabanyan Bella , Luchinsky Yury
Published: June 2021

The article is devoted to the study of polycode in academic discourse. The purpose of the article is to describe polycode as one of the parameters of academic discourse, understood as a complex social and communicative activity in education. Academic discourse includes subjects, objects, and products of communication in a particular social environment. The article raises the question of the use of polycode in the educational environment at the university. Polycode is understood as a strategy, or a technique by which participants of communication are influenced by complex code systems. It is proved that in the terms of modern technological progress, new technologies help to use the effective ways of presenting information during academic discourse based on computer technologies, various resources and services, that is a combination of various semiotic codes. Linguocognitive and linguopragmatic approaches are actual in the determination and selection of semiotic codes, both verbal and non-verbal and necessary for certain educational situation. The study emphasizes that most modern texts are multimodal, created and represented by various semiotic codes and channels, as well as modes (image, writing, speech, etc.) of communication.
Innovative methods of providing food security of the penitentiary system
Authors: Firsova Irina , Pyrchenkova Galina , Radchenko Elena
Published: June 2021

The objective need to reduce the budget expenditures on food for persons held in correctional institutions forces us to find ways to use the available resources more effectively. When dealing with food provision issues, it is necessary to keep in mind food security, that is, the stability of supplies and the availability of stocks in the required volume. Increasing the level of self-sufficiency in food in the penitentiary system of the Russian Federation with the simultaneous optimization of production costs for manufactured products looks like an obvious way to reduce budget expenditures. In the authors’ opinion the presence of own agricultural producers (correctional institutions, as well as their subsidiary farms, federal state unitary enterprises engaged in agricultural activities) makes it possible to manufacture products with a minimum cost close to the production cost. In this aspect, it becomes very important to improve the organization of production processes through the use of software products. The article considers the advantages of using information and communication technologies in crop production and defines ways to optimize costs and reduce budget expenditures on food provision for convicts.

Published: June 2021

Eine 6 Monate alte Französische Bulldogge wurde aufgrund von chronischem Dickdarmdurchfall über 4 Monate vorgestellt. Die Diagnostik des überweisenden Tierarztes hatte Hinweise auf eine chronisch entzündliche Darmerkrankung ergeben, doch war die Therapie (Futtermittelumstellung, antibakterielle, anthelminthische, antiinflammatorische und immunsuppressive Medikation) erfolglos geblieben. Mittels Endoskopie sowie histologischer Untersuchung entnommener Gewebeproben wurden ausgeprägte Erosionen und Ulzerationen der Kolonschleimhaut detektiert. Durch Fluoreszenz-in-situ-Hybridisierung ließen sich invasive Escherichia coli-Bakterien in der Kolonschleimhaut und in Kolonmakrophagen nachweisen und damit eine granulomatöse Kolitis diagnostizieren. Der Hund zeigte unter 8-wöchiger Therapie mit Enrofloxacin eine vollständige Remission der klinischen Symptomatik. Diese Kasuistik beschreibt die erste erfolgreiche Behandlung einer granulomatösen Kolitis mit Enrofloxacin bei einer vergleichsweise jungen Französischen Bulldogge in Deutschland und soll den Leser für diesen Erkrankungskomplex bei (jungen) Hunden sensibilisieren.

Published: June 2021

An efficient and straightforward approach has been established for the preparation of a new class of depsipeptide structures via isocyanide-based consecutive Bargellini–Passerini multicomponent reactions. 3-Carboxamido-isobutyric acids bearing an amide bond were obtained via Bargellini multicomponent reaction from isocyanides, acetone, and chloroform in the presence of sodium hydroxide. Next, via a Passerini multicomponent-reaction strategy, a new class of depsipeptides was synthesized using the Bargellini reaction products, isocyanides, and aldehydes. The depsipeptides thus prepared have more flexible structures than their pseudopeptidic analogues.

Objective Previous work categorized skull base chordoma (SBC) into three genetic risk groups based on 1p36 and homozygous 9p21(p16) deletions, accounting for a wide variability in prognosis (A = low-risk, B = intermediate-risk, C = high-risk). However, it remains unclear how these groups could guide management.

Study Design By integrating surgical outcome and adjuvant radiation (AdjXRT) information with genetic data on 152 tumors, we sought to develop an evidence-based management algorithm for SBC.

Results Gross total resections (GTRs) were associated with improved progression free survival (PFS) in all genetic groups. For Group C tumors, GTR and AdjXRT independently contributed to PFS (multivariate Cox proportional hazard ratio [HR] = 0.14, p = 0.002, and HR = 0.40, p = 0.047, respectively). For Group B tumors, AdjXRT improved outcomes only when GTR was not feasible (log-rank p = 0.008), but not following GTR (log-rank p = 0.54). However, 24 of 25 Group A tumors underwent GTR, and AdjXRT for these did not confer any benefit (log-Rank p = 0.285). The high GTR rates in Group A could be explained by smaller tumor sizes (mean = 0.98cc/4.08cc/4.92cc for Group A/B/C, respectively, p = 0.031) and lack of invasiveness. Group A tumors were also more frequently diagnosed in young people (p = 0.002) as asymptomatic lesions (p = 0.001), suggesting that they could be precursors to tumors in higher risk groups.

Conclusion Genotypic grouping by 1p36 and homozygous 9p21(p16) deletions can predict prognosis in SBC and guide management. GTR remains the cornerstone of SBC treatment and can be sufficient without AdjXRT in low and intermediate risk tumors. Low-risk tumors are associated with a less invasive phenotype, which makes them more amenable to GTR.

Traumatic groin pain syndrome is the result of an acute trauma, usually an indirect muscle injury (i.e., an overstretching of the muscle fibers). The most affected muscles in traumatic groin pain syndrome are rectus abdominis, adductors, and iliopsoas. The internal obturator muscle lesion is very rare. The internal obturator muscle externally rotates the thigh and contributes to the stabilization of the hip joint and its indirect injury may cause the onset of traumatic groin pain syndrome. This case report describes a rare indirect injury of internal obturator in a 29-year-old professional male soccer player.

Purpose The aim of this article is to illustrate the recent framework necessary to standardize studies on groin pain and review the existing literature on groin pain in football.

Methods The common pathological processes underlying groin pain such as muscle, tendon or ligament strain, bone injury or fracture, sport hernia, bursitis, osteitis pubis, and hip-related diseases have been reviewed and current management options have been considered.

Results Groin pain is considered a pain in pubic or lower abdominal or adductors region which can be monolateral or bilateral. It is common in high-intensity team sports and can negatively affect an athlete's professional carrier, causing serious disruption in the performance. Despite a high prevalence of groin pain in athletes, diagnosis and management of the underlying pathological processes remain a challenge for surgeons, radiologists, and physiotherapists alike.

Conclusion A multidisciplinary approach is essential for patients with groin pain allowing prompt diagnosis and initiation of treatment thus facilitating more rapid return to play and preventing potential long-term sequelae of chronic groin pathology.

The study aimed to evaluate the ocular motility and visual and optic disc abnormalities in children diagnosed with periventricular leukomalacia (PVL). A retrospective analysis was performed on 51 consecutive children who had ophthalmic symptoms and were diagnosed with PVL by using magnetic resonance imaging. The patients were assessed for visual function, strabismus, cycloplegic refraction, fundus examination, and if appropriate, spectral-domain optical coherence tomography and visual field testing were applied. The primary outcome measures were the prevalence and visual and ocular motility dysfunctions. Mean age was 5.72 ± 2.6 years (range = 1–12), median birth weight was 2,740 g (range = 1,240–3,460), and median gestational age was 34 weeks (range = 28–38). In total, 21 patients (39.6%) had neurological deficit, 11 (21.5%) had intellectual disability, and 19 (37.2%) had no neurological symptom. In the spherical equivalent refractive error and cylinder power analysis, 10 patients had ≥3.0 D myopia, 15 had ≥3.0 D hyperopia, and eight had ≥2.50 D astigmatism. Thirteen (25.4%) children had a best-corrected visual acuity between 20/40 and 20/20 for Snellen card, while 9 (17.6%) had strabismic amblyopia and 6 (11.7%) had anisometropic amblyopia. Manifest strabismus was present in 35 patients (68.6%); of whom 12 had esotropia (23.5%), 16 had exotropia (31.3%) and 6 had vertical deviation (11.7%). Manifest or latent nystagmus was detected in 14 patients (27.4%). In 28 patients (54.9%), there was optic nerve abnormality. Two patients had hypoplastic disc, 14 had optic disc pallor, 7 had large cupping, and 5 had total optic atrophy. Six subjects underwent reliable visual field (VF) examinations, and all six had abnormal VFs, with inferior fields being most affected. Ocular motility disorders, optic nerve abnormalities, VF defects, and low visual acuity are common findings in this cohort of PVL patients and maybe the only presenting signs of the disease. The recognition of the visual disabilities and implementation of early rehabilitation may have a significant benefit in these children.
Current Treatment Guidelines of SARS-CoV-2 Related Multisystem Inflammatory Syndrome in Children: A Literature Review and Expert Opinion

Multisystem inflammatory syndrome in children (MIS-C) is a systemic disorder that seems to be associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Since April 2020, there have been multiple reports about children with this new condition worldwide, including Europe, Asia, Latin America, and North America. The symptoms of this syndrome mimic the clinical manifestations of Kawasaki disease; therefore, the treatment of Kawasaki disease, as well as supportive care, was the management of choice in children with MIS-C in the early days of recognizing it. It is important to precisely ascertain the risk of COVID-19 infection and its severity in children and to acknowledge the management of this syndrome, with reliable data from cohorts, trials, and experts' opinions. In the current review, we summarize the current management guidelines for MIS-C and present our own protocol to answer some clinical questions regarding MIS-C management during the COVID-19 pandemic.
