From sellers' screens to buyers' screens: Screen-to-Screen Smartphone App to digitize all types of print receipts, invoices and paper documents for sustainability and green development
Authors: Moustafa Khaled
Published: December 2022

Billions of purchasing receipts, invoices and bills are printed every year worldwide. Manufacturing paper and printing involve large quantities of natural resources (trees, water and energy) while producing large amounts of chemical pollutants and greenhouse gases in the atmosphere. If visual smartphone-scannable codes (VSC) can be developed to encrypt and store large amounts of texts such as purchasing receipts and invoices, and if a smartphone application (App) is developed to scan such codes “from screen-to-screen” (sellers’ screens to buyers’ screens), substantial amounts of environmental resources can be saved and considerable amounts of chemical pollutants and green gas emissions can be avoided. For this purpose, a smartphone App, called “Screen-to-Screen” (STS) is proposed to transfer purchasing receipts and invoices directly from sellers’ monitor displays (i.e., supermarkets, stores, restaurants, pharmacies, etc.) to customer smartphones’ screens without the need to print them anymore. Customers should need only to scan visual scannable codes (VSC) that encrypt purchasing details to convert them into digital formats on the customers’ smartphones screens. As a result, significant amounts of energy, trees, and water can be protected, and important amounts of environmental wastes and chemicals (inks, plastics) used in paper manufacturing and printing can be saved for more vital needs than for printing.

Published: December 2022

The paper studies the establishment of work experience programs in the context of the Greek Higher Education Institutions (HEIs) and connects it with the attempts to include Work-Based Learning (WBL) in the education system on a large scale. Emerging challenges caused by two significant recent changes in the Greek Higher Education landscape set the aim of this study. The integration of Technological Education Institutions in Higher Education Institutions and a significant financial change initiated by the new law which transfers the cost of compensation for traineeships to host institutions and not to Operational Programs. The paper presents the current state of the art in the Greek Higher Education and provides a detailed analysis of the existing barriers. The particular study acquires special interest in light of the intensification of the efforts made all over the world aiming to improve the organization and implementation of such interventions. Work experience programs offered by HEIs are required to be better adjusted to the special educational and labor market characteristics of each country and to become more effective. In Greece, the educational and the labor market policy framework recognizes the significant contribution of WBL in general and of traineeships in particular to the development of the appropriate professional knowledge and competences by higher education students. At the same time, traineeships can operate as a communication channel between educational institutions, businesses and social partners, which facilitates their multifaceted information exchanges. Considering, however, the operational autonomy that has been granted to HEIs in Greece, each University develops its own strategy as regards the connection between higher education studies and the labor market. The research presented in the paper constitutes a quantitative analysis of all the types of traineeships implemented by the Greek HEIs with special reference to certain axes, the optional or mandatory character of WBL, the awarded ECTS, similarities of WBL within the same scientific field in different HEIs, the possibility to undergo a WBL placement abroad.
How to get from ‘AI Tools’ to ‘AI Selves’
Authors: Gabora Liane
Published: December 2022

Recent programs such as ChatGPT and Dall E-2 are captivating, the AI powering them is impressive, and their outputs are creative. However, there is a tradition of defining creativity in terms of, not external products, but internal transformation during a creative task. This kind of creativity requires selfhood not just at the bodily level, but at the level of one's thoughts, beliefs, and ideas. Both levels of selfhood have been modelled using autocatalytic networks. The paper discusses how he architecture of autocatalytic networks allows the emergence of a ‘self,’ and notes that current AI programs do not possess this kind of structure.
Distribution-dependent representations in auditory category learning and generalization
Authors: Gan Zhenzhong , Zheng Lurong , Wang Suiping , Feng Gangyi
Published: December 2022

A fundamental objective in Auditory Sciences is understanding how people learn to generalize auditory category knowledge in new situations. How we generalize to novel scenarios speaks to the nature of emergent category representations and generalization mechanisms in handling perceptual variabilities and novelty. The dual learning system (DLS) models propose that auditory category learning involves an explicit, hypothesis-testing learning system, which is optimal for learning rule-based (RB) categories, and an implicit, procedural-based learning system, which is optimal for learning categories requiring pre-decisional information integration (II) across acoustic dimensions. Although DLS describes distinct mechanisms of two types of category learning, it is yet clear the nature of acquired representations and how we transfer them to new contexts. Here, we conducted three experiments to examine differences between II and RB category representations by examining what acoustic and perceptual variabilities affect learners’ generalization success. Learners can generalize to different sets of untrained sounds after only eight training blocks for both II and RB categories. The category structures and novel contexts differentially modulated the generalization success. The II learners significantly decreased generalization performances when categorizing new items derived from an untrained perceptual area and in a context with more distributed samples. In contrast, RB learners’ generalizations are resistant to changes in perceptual regions but are sensitive to changes in sound dispersity. Representational similarity modeling revealed that the generalization in the more dispersed sampling context was accomplished differently by II and RB learners. II learners increased representations of perceptual similarity and decision distance to compensate for the decreased transfer of category representations, whereas the RB learners used a more computational cost strategy by default, computing the decision-bound distance to guide generalization decisions. These results suggest that distinct representations emerged after learning the two types of category structures and using different strategies and flexible mechanisms in resolving generalization challenges when facing novel perceptual variability in new contexts. These findings provide new evidence for dissociated representations of auditory categories and reveal novel generalization mechanisms in resolving different variabilities to maintain perceptual constancy.
The effects of life experiences and polygenic risk for depression on the development of positive and negative cognitive biases across adolescence: The CogBIAS hypothesis
Authors: Zavlis Orestis , Parsons Sam , Fox Elaine , Booth Charlotte , Songco Annabel , Vincent John Paul
Published: December 2022

Background: Little is understood about the development of cognitive biases, despite their influential role in psychopathology and wellbeing. The Cognitive Bias (CogBIAS) hypothesis proposes that cognitive biases develop as a function of environmental influences (which determine the valence of biases), and the genetic susceptibility to those influences (which determines the potency of biases). The current study employed adolescent data from the CogBIAS Longitudinal Study to examine the CogBIAS hypothesis, using a polygenic-by-environment approach. Methods: Measures of life experiences and polygenic scores for depression were used to examine the development of memory and interpretation biases in a three-wave sample of adolescents (12-16 years). Mixed effects modeling was used to examine whether (negative and positive) life experiences, polygenic scores, and their interaction predicted various forms of the memory and interpretation biases. Results: Positive life experiences were shown to, respectively, diminish and enhance the negative and positive forms of memory recall and interpretation biases. Against expectation, negative life experiences and depression polygenic scores were not significant predictors of any cognitive outcomes, upon adjusting for psychopathology. Nonetheless, the interaction between polygenic risk and positive life events predicted a stronger positive social interpretation bias. Conclusions: These results provide the first line of polygenic evidence to support the CogBIAS and vantage sensitivity hypotheses, by demonstrating that polygenic risk for depression could interact with positive environmental influences to produce positive psychological outcomes during adolescence.
Dealing with Crucial Aspects of Action Research
Authors: Sharma Lok Raj
Published: December 2022

Action research, which is a dynamic iterative process, is a deliberate and solution-oriented investigation accomplished collectively or personally in order to solve an existing problem. It entails the participants who scrutinize their own instructive practice systematically and cautiously. It is characterized by spiraling cycles of problem identification, systematic data collection, reflection, analysis, actions taken based on data, and finally problem redefinition. It is an applied form of inquiry useful in divergent situations. It involves such people who keep working to improve their performances, skills, strategies and techniques. The prime objective of this article is to deal with the crucial aspects of action research, such as definitions of action research, field of action research, process, steps, principals, characteristics, benefits and demerits of action research. This article has been prepared on the basis of secondary data gathered from research books and journal articles. It is useful especially to the researchers, because it focuses on the indispensable aspects of action research, and it is undoubtedly necessary for them to have basic ideas about its underlying facets to carry out action researches in their real life situations.

Published: December 2022

Organic manure contributes carbonaceous matter to soil, which when decomposed, offers mineral nutrients to plants, also acts as a base exchange material, and helps to improve the physical, chemical, and biological aspects of soil. This study was conducted to assess the amount of total nitrogen, available phosphorous, available potassium, pH, under various organic manure sources. Collected organic matter samples were tested for total nitrogen, available phosphorus, available potassium, soil organic matter, and pH at the soil laboratory of Nepal Polytechnic College, Bharatpur-11, Chitwan, using the NARC, Soil Science Research Centre, Khumaltar, Lalitpur standard rating. The overall nitrogen concentration of goat dung was 1.667%, whereas buffalo manure had the lowest at 0.665%. The available phosphorus content of organic manure in the research area ranged from 0.732% in vermi-compost to 0.432% in compost, with substantial differences amongst manure samples. The goat manure had the highest potassium level (0.853%), whereas buffalo manure had the lowest (0.513%).  The pH value of goat manure was 8.4 while the pH content of compost manure was 7.567. The maximum amount of organic matter (54.8) was found in buffalo manure, while the lowest (46.3) was found in vermi compost. The maximum amount of organic matter (54.8%) was found in buffalo manure, while the lowest (46.3%) was found in vermi compost. Modern technology must be adapted for successful and improved manure production. To increase the availability and maintenance of nutrients in organic manure, methods such as covering the manure to protect it from rain and sun, avoiding waterlogged conditions, and correct manure decomposition can be implemented.

Published: December 2022

Lentil collar rot disease caused by Sclerotium rolfsii Sacc. is an  important disease causing significant yield loss in Nepal. Seven Trichoderma spp. isolates collected from different regions of Nepal were tested for their capacity to inhibit mycelial growth of Sclerotium rolfsii in in-vitro condition. Experiment was conducted in Completely Randomized Design with four replications in the plant pathology laboratory of Grain Legumes Research Program, Khajura, Banke during 2020. Dual culture method was performed to assess the efficacy of Trichoderma isolates. Trichoderma spp. isolates inhibited mycelial growth of S. rolfsii to various degrees ranging from 48.33-72.47% after 120 hours of inoculation. Maximum colony inhibition of S. rolfsii (72.47%) was obtained by Kapilvastu isolate followed by Nepalgunj isolate (67.72%). Minimum colony inhibition of S. rolfsii (48.33%) was obtained by Mangalpur, Chitwan isolate followed by Rampur, Chitwan isolate (49.33%). Among seven Trichoderma isolates, two isolates (Kapilbastu and Nepalgunj) showed good antagonistic activity against S. rolfsii and were also highly competitive in in-vitro condition. These isolates would therefore be useful in biological disease management.
Factors Affecting Investment Decisions of Employees Working on Financial and Non-Financial Sectors: A Case of Pokhara Metropolitan City, Nepal
Authors: Chapagain Ramkrishna , Dhungana Bharat Ram , Karmacharya Bibek
Published: December 2022

The emergence of the financial market favorably influences the economy. The choices of an individual engaging in the financial market have a crucial part in setting the market trend, which subsequently affects the economy. This research seeks to examine the variables impacting the investment choices of people functioning in financial and non-financial sectors. The research employs a social survey design, based on 280 samples obtained by a structured questionnaire employing a convenience sampling approach. The study was restricted to the Pokhara metropolitan city of Nepal. Descriptive Statistics, Chi-square test, t-test, ANOVAs, Confirmatory Factor Analysis and Structural Equation Modeling were utilized to fulfill the study goals. The study demonstrates that there is no substantial difference between personnel working in the financial and non-finance industries on herding, market, heuristic and demographic component. However, people working in the financial industry examine more economic aspects and the total investment performance is greater for employees working in the financial sector. Further, the research reveals that self-confidence, market information, the recommendation of professionals, minimization through portfolio diversification and high-income level increases in interest in investment were the significant influential factors affecting investment decisions of an employee working in financial and non-financial institutions. The CFA establishes a significant link between observable variables and their fundamental constructs. The path analysis demonstrates that Market, Herding, Knowledge and Economic factors has a favorable influence on investment choices. The regulatory authority and related institutions should equip investors in respect of both economic and behavioral elements to make a smart investment choice.

The implementation of Value Added Tax (VAT) policy in Nepal has completed almost 24 years. The paper intends to assess the VAT performance in terms of revenue collection over the past two decades of its implementation. An econometric modeling and descriptive analysis methods have been applied to analyze secondary time series data extracted from Economic Survey 2021. The revenue growth model is applied to calculate the ratio of change in VAT revenue in the current year over the total VAT revenue of the previous year. The data show that VAT collection has been consistently increasing and the collection gap has been decreasing over the years. The major contributing factors are burgeoning import, soaring private consumption, and newly introduced VAT withholding system.

Authors: Bhandari Stallin
Published: December 2022

Kathmandu Valley has been susceptible to surface displacement due to natural as well as anthropogenic causes since a long time. Previous studies till 2017 suggest that displacement (specially subsidence) with rates of several centimeters per year have occurred in the Kathmandu Valley indicating uncontrolled groundwater withdrawal as the major cause. Owing to the history of surface displacement, this study aims at detecting the nature of land subsidencein Kathmandu for years: 2017 (18th January to 26th December) and 2019 (2nd January to 28th December) based on Persistent Scatterer Interferometry (PSI) technique using Synthetic Aperture Radar (SAR) datasets from Sentinel 1. PSI is able to detect persistently backscattering targets and evaluate respective displacements from the backscattered signal. The results of 2017 and 2019 revealed significant displacement of -100.54mm and -129.19mm along Line Of Sight (LOS) of radar during the study period at Baluwatar and Lazimpat area of Kathmandu district respectively. Similarly, New Baneshwor, Bode and Imadol exhibited a substantial displacement of -88.81mm,-103.55mm, -127.35mm respectively for year 2019.

Monosodium glutamate is a common food additive that belongs to the group of flavor enhancers used in a wide range of food products. The potentially negative impact of monosodium glutamate on human health prompts us to question the safety of its widespread use. The article presents and analyzes the data of an experimental study conducted on 40 white male and female rats of reproductive age (2.5-3.5 months old) weighing 120-190 g. The purpose of the study is to study histological, morphometric, and ultrastructural changes in the lymph nodes of rats under conditions of short-term exposure to monosodium glutamate. An experimental group of animals (10 male rats, 10 female rats), which was on a standard vivarium diet, was given monosodium glutamate at a dose of 0.07 g/kg of rat body weight by pipette every day at the same time for four weeks, followed by free access to water and food. In animals of the intact group, the structure of mesenteric lymph nodes corresponded to the species norm. In the experimental group of animals, after four weeks of monosodium glutamate exposure, it was found that the paracortical area contained a g larger number of post-capillary venules with a high endothelium compared to the intact and control groups of animals. Changes in the vascular bed were established, in particular, the arteries both in the thickness of the organ and in its hilum contain a thickened wall, their lumen is full of blood. Veins are also full-blooded, dilated and deformed. Swelling of the parenchyma of nodes and signs of immune activity are observed. There is a significant decrease in the relative area of lymphoid nodules and the mantle zone, an increase in the relative area of the medullary substance of the node, corticomedullary index, germinal centers, paracortical area, and medullary cords. Part of lymphocytes of all populations with signs of apoptosis. The other part has an uneven karyolemma contour, the nucleolus is not visualized in all lymphocytes, the cytoplasm is clear and contains organelles. Mitochondria are hypertrophied with a light matrix. Therefore, even a short-term daily exposure to monosodium glutamate, namely four weeks, causes changes in the structural organization of mesenteric lymph nodes.
F. Dostoevsky’s image in T. de Banville’s poem Les Petits Lapins
Authors: Artemiev M. A.
Published: December 2022

In the mid-1880s, the French came to discover Dostoevsky’s works. Yet neither Russian nor foreign scholars have attempted to fnd out when exactly his name was frst mentioned in French fction. This article represents the frst such study. The author believes that Théodore de Banville was the frst French author who introduced Dostoevsky’s name to the poetry of the late 1880s, or can at least be credited with one of the earliest mentions of the Russian writer’s name in French verse. For authors of de Banville’s generation, Dostoevsky remained a trendy foreign writer whose opinions and manner of writing stood in stark contrast with traditional French literary, aesthetic and ethical values. De Banville’s lines about the Russian author are full of irony and mock what the poet views as Dostoevsky’s exaggerated ‘psychologism.’ The article also describes the context for Dostoevsky’s reception, drawing comparisons with other foreign authors who became known to French audiences around the same time. The study contains a comparison between G. Flaubert’s response to L. Tolstoy’s War and Peace [Voyna i mir] and de Banville’s reception of Dostoevsky.
On the genealogy of the ‘Russian nihilist.’ A. Herzen’s and D. Pisarev’s literary-anthropological studies
Authors: Vyazinkin A. Y.
Published: December 2022

In each historical period, starting from the mid-19th c., Russian nihilism represents an uncompromising social and aesthetic response to challenges of political and cultural reality. In order to fully appreciate the phenomenon of Russian nihilism as an inexhaustible supply of literary and philosophical ideas and social and political activism, it is necessary to identify and defne the subject of nihilistic discourse and then trace its genealogy. In their studies, the prominent Russian thinkers A. Herzen and D. Pisarev proposed their original genealogical concepts of the ‘Russian nihilist.’ Their comparative analysis reveals a number of converging points with regard to the artistic and anthropological types preceding the ‘Russian nihilist.’ However, while Pisarev insisted on a continuous, linear and inevitable process that brought about the ‘Russian nihilist,’ Herzen’s historic-philosophical views determined his theory of a more sporadic process.
The religious subtext of A. Chekhov’s Ward No. 6 [Palata nomer shest] and K. Kesey’s One Flew over the Cuckoo’s Nest
Authors: Skvortsova A. V.
Published: December 2022

The article explores the religious subtext of Chekhov’s Ward No. 6 [Palata nomer shest] and K. Kesey’s One Flew over the Cuckoo’s Nest. Both depict a psychiatric facility that can be regarded as a model of a society oppressive to human individuality. The author analyses the portrayals of the main characters, both of whom represent the type of a saviour. One of them, doctor Ragin, fails his ‘soteriological mission,’ whereas the other, McMurphy, succeeds. McMurphy seems to share some features with Christ, and yet others — with an anthropomorphic trickster from Hindu mythology as well as a character of the French carnival theatre, a vestige of medieval festivities partially rooted in Christianity. Both Ragin and McMurphy are tragical characters, but while the former’s death does not bring about any positive change, the latter’s demise results in a spiritual transformation of those around him. The author argues that the compared books describe two diﬀerent reactions to violence: passive submission to circumstances, followed by social and personal degradation, and active defance of abuse, which results in an improved ‘world order.’
Poor Orick! A story of a misprint
Authors: Liutova S. N.
Published: December 2022

The author conducts a case study with the aim of discovering what tends to cut short the careers of promising young writers of every epoch. The paper oﬀers a study and partial reconstruction of the life of the now obscure writer Boris P. Markov, whose works were published in the early 20th c. and whose pen-name B. Orik appears in reference books on literature, albeit misspelt due to a misprint — therefore, a ‘pseudo-pseudonym.’ Markov’s later life, already unconnected to literature, is known to the researcher, who happens to be his great-granddaughter. In order to glean information about his earlier life, S. Liutova pored over archives in Moscow, Saratov, Tambov, Veliky Novgorod,as well as Łowicz and Łodź in Poland, piecing together a comprehensive view of life in Russia at the dawn of the 20th c. The author discovers that a writer’s silence can be a form of unconscious protest. The article’s most intriguing suggestion is that the memories of Markov’s literary circle (the paper infers his connection with Acmeists) and the social context of his early journalism were intentionally suppressed by the family.
John Donne. A growing love: A hundred and twenty best poems translated and retold by Yury Klyuchnikov
Authors: Egorova L. V.
Published: December 2022

Yury Klyuchnikov is a prolifc author who has published a series of translations of French, Suf, Chinese, Indian, and English poetry into Russian. To Donne’s hundred and twenty ‘best’ poems, selected as such by the volume’s compilers, the book does little justice. The review points out the flaws of the dilettante approach adopted by  the translator and the authors of the foreword and aferword alike. The loose retellings of the poems in the book hardly merit the term ‘translations.’ Indeed, Klyuchnikov does not pretend to try to be faithful to the original. The notes and comments in the volume leave the impression of shoddy work. The aferword entitled ‘John Donne — A great English poet and spirit seer’ is authored by S. Klyuchnikov, the translator’s son. His essay reeks of unprofessionalism in the treatment of critical works and various misrepresentations. The book’s co-creators show reluctance in pondering the metaphysical complexity of Donne’s legacy and the multiple levels of meaning contained in his works, compounded by their open mistrust of professional scholars and commentators.
Dostoevsky’s themes in Tolstoy’s The Forged Coupon [Falshiviy kupon]
Authors: Matveeva I. Y.
Published: December 2022

The novella The Forged Coupon [Falshiviy kupon] can be considered one of the most compelling illustrations of the core principle of Tolstoy’s religious philosophy: ‘nonviolent resistance to evil.’ While Tolstoyan anthropology consistently views human nature as inherently good, the novella oﬀers a not unambiguous view of the human soul, which can harbour evil as well. The Forged Coupon is a fascinating example of the indirect dialogue between Tolstoy and Dostoevsky. Dostoevsky’s anthropology and his idea of human nature as a struggle between good and evil appears to play a significant role in Tolstoy’s contemplations. An evil feeling is indeed engendered in the human soul, but with an important caveat that this evil feeling always interacts with external evil. Such an evil combination invariably occurs in the context of broken-off connections, when humanity’s original spiritual integrity is disrupted. In addition, Tolstoy’s later philosophy converges with Dostoevsky’s ideas about the good being a result of the irrational and mystical influence of one man’s spiritual nature on that of another, in a true manifestation of the Christian spirit.
On bounded solutions of linear systems of differential equations with unbounded coefficients
Authors:   International Information Technology University, Uteshova R.Ye. , Kokotova Ye.V. ,   K. Zhubanov Aktobe Regional University
Published: December 2022

This paper deals with a problem of finding a bounded solution of a system of nonhomogeneous linear differential equations with an unbounded matrix of coefficients on a finite interval. The right-hand side of the equation belongs to a space of continuous functions bounded with some weight; the weight function is chosen taking into account the behavior of the coefficient matrix. The problem is studied using a modified version of the parameterization method with non-uniform partitioning. Necessary and sufficient conditions of well-posedness of the problem are obtained in terms of a bilaterally infinite matrix of special structure.

The paper studies a two-point boundary value problem with unlimited boundary conditions for a linear singularly perturbed differential equation. Asymptotic estimates are given for a linearly independent system of solutions of a homogeneous perturbed equation. Auxiliary, so-called boundary functions, the Cauchy function are defined. For sufficiently small values of the parameter, estimates for the Cauchy function and boundary functions are found. An algorithm for constructing the desired solution of the boundary value problem has been developed. A theorem on the solvability of a solution to a boundary value problem is proved. For sufficiently small values of the parameter, an asymptotic estimate for the solution of the inhomogeneous boundary value problem is established. The initial conditions for the degenerate equation are determined. The formula is determined; the phenomena of the initial jump are studied.

Multiparametric difference schemes of the finite element method of a high order of accuracy for the Sobolevtype equation of the fourth-order in time are studied. In particular, the first boundary value problem for the equation of ion-acoustic waves in a magnetized plasma is considered. A high-order accuracy of the scheme is achieved due to the special discretization of time and space variables. The presence of parameters in the scheme makes it possible to regularize the accuracy of the schemes and optimize the implementation algorithm. An a priori estimate in a weak norm is obtained by the method of energy inequality. Based on this estimate and the Bramble-Hilbert lemma, the convergence of the constructed algorithms in classes of generalized solutions is proved. An algorithm for implementing the difference scheme is proposed.
Systems of integral equations with a degenerate kernel and an algorithm for their solution using the Maple program

In the mathematical literature, a scalar integral equation with a degenerate kernel is well described (see below (1)), where all the written functions are scalar quantities). The authors are not aware of publications where systems of integral equations of (1) type with kernels in the form of a product of matrices would be considered in detail. It is usually said that the technique for solving such systems is easily transferred from the scalar case to the vector one (for example, in the monograph A.L. Kalashnikov "Methods for the approximate solution of integral equations of the second kind" (Nizhny Novgorod: Nizhny Novgorod State University, 2017), a brief description of systems of equations with degenerate kernels is given, where the role of degenerate kernels is played by products of scalar rather than matrix functions). However, as the simplest examples show, the generalization of the ideas of the scalar case to the case of integral systems with kernels in the form of a sum of products of matrix functions is rather unclear, although in this case the idea of reducing an integral equation to an algebraic system is also used. At the same time, the process of obtaining the conditions for the solvability of an integral system in the form of orthogonality conditions, based on the conditions for the solvability of the corresponding algebraic system, as it seems to us, has not been previously described. Bearing in mind the wide applications of the theory of integral equations in applied problems, the authors considered it necessary to give a detailed scheme for solving integral systems with degenerate kernels in the multidimensional case and to implement this scheme in the Maple program. Note that only scalar integral equations are solved in Maple using the intsolve procedure. The authors did not find a similar procedure for solving systems of integral equations, so they developed their own procedure.
CONCEPTUAL FOUNDATIONS OF SELF-SIGNIFICANCE IN THE CONTEXT OF THE REFLEXIVE «SELF-CONCEPT»
Authors: Livandovska Inna , Kominarets Alexander
Published: December 2022

The article considers the category of self-importance in the context of the reflexive «Self-concept». This definition is considered as a symbiosis of reflection and the affective sphere, which coordinates a number of functions: self-determination, linking and organizing the external and internal perception of reality by a person. Concepts of self-importance, showing possible inconsistencies and intersections between its elements in the context of a reflexive «Self-concept» are structured. In the article, the authors tried to generalize and supplement the opinions of researchers regarding this phenomenon.
The discovery of such a category as an image of one's own self was a significant event in the field of psychology. Each person has a subjective, mental image or portrait of himself. However, there is a problem of its perception by the individual. Sometimes the projection of the Self is not consciously perceived, but remains at the level of the unconscious in the smallest details.
The concept of self-importance is a component of the reflexive «Self-concept», the study of this phenomenon is one of the most pressing problems of the present, because it allows you to better understand how exactly the formation of personality occurs, and what factors influence this formation, and if necessary, make adjustments.
Speaking about present science development, the problem of significance is actively studied by both foreign (A.Bandura, Y.Zaitseva, D.Bujenthal, M.Kagan, E.Erikson, X.Kohut, K.Rogers, V.Frankl,) and domestic scientists (O.Furman, G.Chaika, K.Fomenko, K.Gavrilovskaya, O.Kondratyuk, E.Kalyuzhnaya). In their research, scientists described in detail the phenomenon of «Self-concept», drawing attention to the main problems faced by the emerging individual and possible ways to solve them.
Based on the described understanding of PVZ, we have opened up new perspectives for understanding what and how determines a person's behavior and life activity. This allows us to take a fresh look at the fact that not only inconsistencies, but also contradictions are possible between significance for oneself, for others, and significance in oneself, to highlight the internal work for combining external and internal perception of reality, as well as to empirically investigate the mechanisms of self-determination, protection, and human development both in ontogenesis and in phylogenesis in the context of this problem.
Key words: reflection, «Self–concept», affective sphere, significance, concept of self-significance.

The paper analyses the results of experimental studies of samples of rectangular plates working in two directions while resting them inthecorners.Thespecimenscombinewithdifferent materials: heavy monolithic concrete, prefabricated blocks of lightweight concrete, metal and composite reinforcement. The combined reinforcement allows to reduce weight of the specimens and gives new properties for structure during the operation. These properties are caused by different combinations of materials, their rational placement and peculiarities of physical and mechanical characteristics. Analysis of the results (indicators of strength, cracking resistance, deformability, schemes of fracture) was carriedoutbycomparingthetypesofreinforcement, its amount, as well as changes in the strength of heavy concrete. It has been found that partial swap metal reinforcement (in the middle zone of slabs) for the composite reinforcement slightly reduces the strength, decreases rigidity and cracking resistance, and changes the mechanism of specimen failure.

Heat supply networks in Tyumen region are characterized by a high damage rate, and as a result increase heat losses and reduce operating efficiency of heat supply networks. Reducing the reliability of heating networks increases the cost for their operation, for the elimination of the consequences of accidents and the restoration of the urban environment. The authors of this article consider that the cause of increased pipeline failure is internal corrosion damage and its consequences, detected in the operation at the resource supply company in Tobolsk during the heating periods of 2018-2022. An analysis of the source of the internal corrosion appearance on steel pipelines of different diameters and different types of laying was carried out, an attempt to determine the correlation between external corrosion layer and internal one was made, the influence of the oxygen content in the heat transfer fluid was taken into account. During preparing the article, different variants to minimize the corrosion damage of the internal pipeline surface and to reduce the level of oxygen dissolved in the aqueous environment have been considered.

Тhe article reviews examples of design and comparison of supply, exhaust and supply-and-exhaustvent il ationsystems inparticularrooms of the office center in the city of Tobolsk. The advantages of the device of supply-and-exhaust units with a heat recovery in rooms with excess heat are considered. The design schemes of two variants of ventilation systems are given: autonomous and supply-and-exhaust. Aerodynamic calculations of ventilation systems were performed and presented in the form of tables. A technical and economic comparison of the version of the ventilation system with a plate heat recovery and the version without it was carried out. The ventilation equipment was selected. Summing up the results, it can be concluded that it is advisable to use the option of designing a supply-and-exhaust ventilation system with a plate heat recovery. Besides, the authors consider the methods of heat energy recovery in the supply-and-exhaust ventilation systems in particular office premises, which significantly reduce the consumption of thermal and electrical energy. Designs with a heat recovery eliminate unnecessary costs for heating the outside air. Due to the constant increase in tariffs for basic energy resources, air recovery becomes necessary and uses in the design of ventilation systems.
