Authors: Momeni Kasra , Ji Yanzhou , Chen Long-Qing
Published: October 2021

The exotic properties of 2D materials made them ideal candidates for applications in quantum computing, flexible electronics, and energy technologies. A major barrier to their adaptation for industrial applications is their controllable and reproducible growth at a large scale. A significant effort has been devoted to the chemical vapor deposition (CVD) growth of wafer-scale highly crystalline monolayer materials through exhaustive trial-and-error experimentations. However, major challenges remain as the final morphology and growth quality of the 2D materials may significantly change upon subtle variation in growth conditions. Here, we introduced a multiscale/multiphysics model based on coupling continuum fluid mechanics and phase-field models for CVD growth of 2D materials. It connects the macroscale experimentally controllable parameters, such as inlet velocity and temperature, and mesoscale growth parameters such as surface diffusion and deposition rates, to morphology of the as-grown 2D materials. We considered WSe2 as our model material and established a relationship between the macroscale growth parameters and the growth coverage. Our model can guide the CVD growth of monolayer materials and paves the way to their synthesis-by-design.

Authors: Olkhovska Viktoriia , Yeloyeva Zalina , Olkhovskyi Yevhen
Published: October 2021

The aim of the work was to study the characteristics of the response of non-specific protective factors in tonsillitis of streptococcal etiology in children infected and uninfected with HHV-6 infection at different periods of the disease.
Materials and research methods. In 78 children aged 3–15 years, inflammation markers and phagocytic activity of peripheral blood neutrophils (PAN) were determined using the nitroblue tetrazolium reduction test. The studies were carried out in the acute period and in the period of convalescence. Mathematical and statistical processing of the data obtained was carried out using Microsoft Excel 2003 and Statistica 6.0 programs. The significance of differences between the mean values was determined using the Student's test (t).
Results. It was found that infection of children with HHV-6 leads to a decrease in the functional activity of neutrophils in the onset of streptococcal tonsillitis compared with uninfected patients (p<0.05). Also, the acute period of streptococcal tonsillitis in patients with co-infection is accompanied by a violation of the functional reserve of the oxygen-dependent mechanism of bactericidal neutrophils: minimal opportunities were found in tonsillitis on the background of HHV-6 infection (p<0.05). By the period of convalescence, a decrease in the indicators of the functional activity of neutrophils, increased in the acute period, was recorded, but in children infected with HHV-6, a complete recovery of indicators to the physiological norm did not occur. One of the features of streptococcal tonsillitis in children with HHV-6 infection is an increase in serum gamma globulin level (p˂0.05), lack of significant dynamics of decrease in the ASL-O indicator.
Conclusions. The presence of VHL-6t infection in a child with streptococcal tonsillitis adversely affects the state of nonspecific protective factors, in particular PAN. The obtained data must be used to optimize the management of patients at different periods of the disease, including at the stages of dispensary observation
Development and use of the program of automatic problem solving when conducting practical classes in physics at the university
Authors: Shamshin Alexandr
Published: October 2021

The creation of a virtual educational environment, consisting of an information space that ensures the availability of unlimited educational material through communication means, a virtual or real communication channel between a student and a teacher, increases the role of self-education, the dominance of learning over teaching. Paraphrasing [1], we can say that physics is owned not by the one who knows the formulas and definitions, but by the one who, with their help, can solve physical problems (PP). Similarly to the words of E. Fermi [2]: "A person knows physics if he/she can solve problems." The ability to solve PP contributes to the concretization of students' knowledge; without it, there is a separation of theoretical, lecture, educational material from the main task of any learning process – the practical application of accumulated knowledge and skills. Solving of PP contributes to the development of mental activity, the formation of creativity, intelligence, observation, independence and accuracy, is one of the forms of repetition, control and assessment of knowledge. At the same time, it is the solution of problems that is the most difficult element of physical education, causing methodological, didactic, psychological, and mathematical difficulties.
It is known, that along with the traditional methods of solving PP: arithmetic, algebraic, geometric, graphic, experimental, since the beginning of the 2000s, information technology, computer technology, and programs - answer books have been actively used. The traditionally difficult issue of solving problems in physics requires both the improvement of classical methods and the development of new software tools for solving problems. The paper discusses the possibilities of using computers to solve various types of physical problems, the use of a site, created by the author, with considered examples of solving more than 2500 problems in physics, a developed program for automatic solution of problems in physics (APS - automatic physics solver) during practical exercises.
OPTIMIZATION OF TIMETABLE AT THE UNIVERSITY
Authors: Kosolap A. I. , Dubovik T. M.
Published: October 2021

Context. In this paper, we consider a well-known university scheduling problem. Such tasks are solved several times a year in every educational institution. The problem of constructing an optimal schedule remains open despite numerous studies in this area. This is due to the complexity of the corresponding optimization problem, in particular, its significant dimension. This complicates its numerical solution with existing optimization methods. Scheduling models also need improvement. Thus, schedule optimization is a complex computational problem and requires the development of new methods for solving it. 

Objective. Improvement of optimization models for timetabling at the university and the use of new effective methods to solve them.

Method. We use the exact quadratic regularization method to solve timetabling optimization problems. Exact quadratic regularization allows transforming complex optimization models with Boolean variables into the problem of maximizing the vector norm on a convex set. We use the efficient direct dual interior point method and dichotomy method to solve this problem. This method has shown significantly better results in solving many complex multimodal problems. This is confirmed by many comparative computational experiments. The exact quadratic regularization method is even more effective in solving timetabling problems. This optimization method is used for the first time for this class of problems, so it required the development of adequate algorithmic support.

Results. We propose a new, simpler timetabling optimization model that can be easily implemented software in Excel with the OpenSolver, RoskSolver, and others. We give a small example of building a schedule and describe step-by-step instructions for obtaining the optimal solution. 

Conclusions. An efficient new technology developed for university timetable, which is simple to implement and does not require the development of special software. The efficiency of the technology is ensured by the use of a new method of exact quadratic regularization.
COMPARISON OF TWO FORMS OF ERLANGIAN DISTRIBUTION LAW IN QUEUING THEORY
Authors: Tarasov V. N.
Published: October 2021

Context. For modeling various data transmission systems, queuing systems G/G/1 are in demand, this is especially important because there is no final solution for them in the general case. The problem of the derivation in closed form of the solution for the average waiting time in the queue for ordinary system with erlangian input distributions of the second order and for the same system with shifted to the right distributions is considered.

Objective. Obtaining a solution for the main system characteristic – the average waiting time for queue requirements for three types of queuing systems of type G/G/1 with usual and shifted erlangian input distributions.

Method. To solve this problem, we used the classical method of spectral decomposition of the solution of Lindley integral equation, which allows one to obtain a solution for average the waiting time for systems under consideration in a closed form. For the practical application of the results obtained, the well-known method of moments of the theory of probability was used.

Results. For the first time, spectral expansions of the solution of the Lindley integral equation for systems with ordinary and shifted Erlang distributions are obtained, with the help of which the calculation formulas for the average waiting time in the queue for the above systems in closed form are derived.

Conclusions. The difference between the usual and normalized distribution is that the normalized distribution has a mathematical expectation independent of the order of the distribution k, therefore, the normalized and normal Erlang distributions differ in numerical characteristics. The introduction of the time shift parameter in the laws of input flow distribution and service time for the systems under consideration turns them into systems with a delay with a shorter waiting time. This is because the time shift operation reduces the coefficient of variation in the intervals between the receipts of the requirements and their service time, and as is known from queuing theory, the average wait time of requirements is related to these coefficients of variation by a quadratic dependence. The system with usual erlangian input distributions of the second order is applicable only at a certain point value of the coefficients of variation of the intervals between the receipts of the requirements and their service time. The same system with shifted distributions allows us to operate with interval values of coefficients of variations, which expands the scope of these systems. This approach allows us to calculate the average delay for these systems in mathematical packages for a wide range of traffic parameters.

Educators as mediators in teaching English as First Additional Language in Grade 6 inclusive classrooms in South Africa
Authors: Chauke Margaret , Tabane Ramodungoane
Published: October 2021

Educators are one of the stakeholders in the education system working to ensure learner success. According to the Minimum Requirements For Teacher Education Qualifications, educators must fulfil 7 roles in their quest to impart education. In the study reported on her, we investigated Grade 6 educators’ knowledge and use of mediation as one of their roles in teaching English as First Additional Language (FAL) in Grade 6 inclusive classrooms. We further investigated how educators responded to learners who had diverse learning needs in English as FAL in Grade 6 inclusive classrooms. Six educators who taught English as FAL were purposively selected to participate in this study. Data were collected using qualitative research methods such as in-depth interviews and observations, in addition to document analysis. The participating educators indicated that large classes, a lack of training on inclusive education, and the scarcity of teaching resources made their mediation roles in teaching English as FAL in Grade 6 inclusive classrooms very challenging.
A case study of two teacher learning communities in KwaZulu-Natal, South Africa
Authors: Zulu Free-Queen Bongiwe , Mukeredzi Tabitha Grace
Published: October 2021

In the Integrated Strategic Planning Framework for Teacher Education and Development, a South African policy, the Department of Basic Education (DBE) and the Department of Higher Education (DHET) call for the formation of professional learning communities and envisage support for teachers and access to enhanced professional development opportunities at the local level. However, the formation and operation of professional learning communities in a South African context is still unclear. In this article we use the concept of professional learning communities to examine the extent to which 2 teacher learning communities operate as professional learning communities. We used interviews, observations, survey questionnaires and document analysis to generate data. The findings of the study reveal that the 2 teacher learning communities were initiated by the DBE and not by teachers. However, the size of 1 teacher learning community and the nature of its functioning seemed to adhere to the characteristics of a professional learning community while the other did not. The findings indicate that professional learning communities that operate in developing contexts might be functional when all the stakeholders play a meaningful role in supporting professional learning communities.
The influence of parental demographics on school choice decision-making in Western Gauteng, South Africa
Authors: Blake Beverley , Mestry Raj
Published: October 2021

Major political changes since 1994 have initiated the pace of change in the South African education system. Parents’ values, traditions and practices that served in the past were no longer relevant in the new dynamic educational environment. Parental school choice and “the right to choose” movement has subsequently come to the fore. The purpose of this article elucidates findings regarding the demographics of active school choice engagement among middle class parents in Western Gauteng, South Africa. The study, situated in the Gauteng province, South Africa, followed a conclusive research design with a post positivist paradigm. Parent questionnaires were distributed to different types of urban schools to establish the perceptions of parents regarding the factors, anxieties, aspirations and strategies influencing school choice decision-making. Findings reveal that language, income and education not only have a definitive influence on active school choice engagement but also affect the level of importance attached to specific school choice factors. Education in South Africa can thus be viewed as a unique complex system embedded in a political, cultural and economic context.

Published: October 2021

The present study is undertaken to study the economics analysis of onion seed production in washim district of Vidarbha.The study was based on primary data. Primary data of 90 farmers pertaining to the year 2018-2019 were collected from three villages and functionaries involved in onion seed procurement chain producer, seed company, retailer were selected for collecting information. The onion seed production is taken on small scale but it contributes sizable share in total earning of the cultivator. However, yield and profit from onion seed cultivation is uncertain because it is very sensitive, it require special attention. To study the economics of onion seed production, the standard cost concepts were used. In estimation of cost of cultivation, seed, rental value of land, human labour and interest on fixed capital were the major cost items.The gross cropped area was highest in large group i.e. 8.28 hectare followed by medium 5.27 ha and small group 2.93. The cropping pattern of onion seed was dominated by soybean, cotton and tur in Kharif season whereas gram and wheat was Rabi season. In Rabi season the contribution of area under onion seed was 12.62, 12.52 and 12.31 per cent by small, medium and large farmers. Per hectare total cost of cultivation of onion seed was highest in the medium group i.e. Rs. 167967.3 per hectare followed by large group Rs. 166102.74 and small group Rs.165161.53.The benefit cost ratio of onion seed at cost ‘C3’ was 1.70 in small group, 1.76 in medium group and 1.78 in large group.
Design peculiarities of pipeline support on landslide slopes
Authors: Leyer Darya , Seryi Dmitry , Lubarsky Nikolai
Published: October 2021

The pipeline construction in complex engineering-geological conditions requires a thorough initial data analysis, as well as complex slope modeling using modern software systems. The article discusses the features of the foundation construction for stand-alone supports for power lines and pipelines on landslide slopes composed of clay soils. Relevant Russian regulations documents administer above-ground pipelining, which significantly complicates the design process. However,
above-ground pipelining allows monitoring the slope condition (formation road edge breakaway), foundations (deviation from the design location), as well as the pipeline (displacement of the route axis, the state of welds). Timely detected deviations allow avoiding an emergency situation.
The author considers possible options for constructive solutions for support foundations, as well as protective structures exemplified by a real Krasnodar Krai object. The pipeline construction in active landslide displacements conditions, as well as the presence of seismic effects, requires not only ensuring the construction's economic feasibility, but also the work safety. In the developing process of optimal design solutions, slope computer modeling was executed both in two-dimensional and three-dimensional formulations based on the finite element method using the Plaxis 2D and Plaxis 3D programs. The considered design situations made it possible to take into account the worst load combinations possible during pipeline operation. According to the calculation results and a comprehensive engineering and geological conditions study at the site, as well as the construction organization peculiarities, a block diagram has been developed that makes it possible to determine the optimal design solutions for protective structures in relation to any landslide construction site.

Published: October 2021

Abstract The objective of this study was to describe and compare mothers’ and teachers’ reports concerning their educational social skills and negative practices and children’s behavioral problems and social skills. The mothers and teachers of 81 children participated in this study. The children were assigned to four groups depending on whether they presented problems exclusively at home, school, in both, or none of these contexts. Valid instruments measured educational practices and child behavior. The results show that: (a) mothers and teachers agreed that children with problems in both contexts presented the highest level of impairment; (b) the mothers more frequently reported skills such as affection, adopted negative practices, and identified problem behaviors; (c) the teachers reported more skills such as limit setting. The conclusion is that teachers’ and mothers’ practices differ, and such information can guide preventive programs and interventions.

Published: October 2021

RESUMEN En el presente trabajo se evaluaron residuos de rocas pizarras del depósito Tchihingue en Angola como posible fuente de materiales cementicios suplementarios, enfocado en la reactividad puzolánica y la composición mineralógica de los residuos de pizarra amarilla y pizarra parda. La caracterización química y mineralógica de residuos de pizarras sin calcinar y calcinados, se realizó por Espectrometría de Absorción Atómica (EAA) y difracción de rayos X (DRX), respectivamente. Ambos residuos de pizarras están compuestas por cuarzo y moscovita, y en la pizarra amarilla se identifica caolinita y en la pizarra parda hematita como fases secundarias. La reactividad puzolánica mediante solubilidad de sílice y alúmina en álcali y el índice de actividad de resistencia con cemento Portland, mostró que la pizarra amarilla calcinada presenta la mayor reactividad, lo cual está relacionado con la presencia de caolinita en la muestra, por ser la fase más activa entre los minerales arcillosos. Los residuos de pizarras evaluados cumplen con los requerimientos químicos y físicos-mecánicos, de acuerdo con la norma ASTM C 618, por lo que se considera que ambos residuos calcinados presentan perspectivas para ser empleados como materiales cementicios suplementarios.
Surface foundation subjected to strike-slip faulting on dense sand: centrifuge testing versus numerical analysis
Authors: Agalianos Athanasios , Korre Evangelia , Abdoun Tarek , Anastasopoulos Ioannis
Published: October 2021

The paper studies strike-slip fault rupture propagation through dense sand and its interaction with surface foundations, combining physical and numerical modelling. A series of centrifuge tests is conducted using a three-section split-box, which allows the modelling of two strike-slip faults per test. A free-field test is initially conducted, followed by four interaction tests. Eight different foundation configurations are studied, varying the foundation location, surcharge load, aspect ratio and rigidity. The experiments are numerically simulated employing three-dimensional finite-element modelling, combining periodic boundaries and a relatively simple yet efficient constitutive model, developed as part of this study. Based on a Mohr–Coulomb yield criterion, the model incorporates post-yield isotropic frictional hardening and softening (MC–HS). Carefully calibrated on the basis of triaxial tests, the model is validated against the centrifuge model tests, and exploited to derive further insights. The MC–HS model covers the entire range from elastic to fully softened response, capturing the deviatoric and volumetric behaviour of dense sand, and especially its pre-softening volumetric response, which is proven to be crucial for the simulation of the complex mechanisms of strike-slip faulting. Both physical and numerical modelling reveal the formation of diagonal shear ruptures at the ground surface (Riedel shears). These are complex helicoidal structures, formed due to the spatial variation of shear stresses. Foundation response is mainly governed by the kinematic constraint offered by its presence. Fault rupture locations close to its sides typically lead to a translational mechanism, whereas locations close to its centreline lead to a rotational one. Foundation rigidity is proven to be a prerequisite for the development of both mechanisms, which rely on the ability of the foundation to resist the developing normal and shear stresses.

Published: October 2021

Twice-exceptional individuals are those that have high cognitive ability in one or more areas, but also have a diagnosed disability. The needs of these individuals likely differ from those with high cognitive ability without a disability and those who solely have a disability. Intervening early can offer exceptional benefits for twice-exceptional individuals, but this has proved challenging due to the high cognitive abilities masking disabilities. This study explores if parent-reported developmental milestones can predict the number of disabilities diagnosed for an individual, including Autism Spectrum Disorder (ASD), Attention-Deficit/Hyperactivity Disorder (ADHD), and Specific Learning Disorder (SLD). Using a clinical sample of about 1,300 individuals, we used a Bayesian cumulative logistic model to explore if developmental milestones are able to predict the number of diagnoses after controlling for IQ and age. Study results show that when an individual began to count and read informed predictions for the number of future diagnoses in the clinical sample. Implications for future study and practitioners are discussed in further detail.

Determining the True Reason for an Alleged Section 187(1)(c) Dismissal: A Discussion of National Union of Metalworkers of South Africa v Aveng Trident Steel (a Division of Aveng Africa (Pty) Ltd) (2021) 42 ILJ 67 (CC)
Authors: Newaj Kamalesh
Published: October 2021

On 27 October 2020, the Constitutional Court handed down judgment in National Union of Metalworkers of South Africa v Aveng Trident Steel (A Division of Aveng Africa (Pty) Ltd) 2021 42 ILJ 67 (CC). Following the judgment, it is now commonplace that the amendment to section 187(1)(c) of the Labour Relations Act, 1995 does not preclude an employer from dismissing employees for a permissible reason, such as its operational requirements, should they refuse to accept a demand.
The court confirmed that in cases such as this where they are faced with two opposing reasons for the dismissal, an impermissible reason on the one hand and a permissible reason on the other, an enquiry must be conducted into what the true reason for the dismissal is. However, the approach to be followed in conducting this enquiry caused dissent. Half of the judges were of the view that the correct approach is to follow the causation test set out in SA Chemical Workers Union v Afrox Ltd 1999 20 ILJ 1718 (LAC), while the other half disavowed reliance on the causation test. Instead, they opted to support the enquiry conducted in Chemical Workers Industrial Union v Algorax (Pty) Ltd 2003 24 ILJ 1917 (LAC).
This case note seeks to establish which approach should be followed in determining the true reason for an alleged section 187(1)(c) automatically unfair dismissal.

Статья посвящена выбору подходящей модели для построения срочной структуры процентных ставок из наиболее популярных: бутстрэпа, различных сплайнов и параметрических моделей Нельсона-Зигеля и Свенссона. Изложены особенности их применения на финансовых рынках стран мира.

Задача моделирования срочной структуры процентных ставок имеет долгую историю и продолжает привлекать повышенное внимание учёных-теоретиков и специалистов-практиков. В разное время этой проблемой интересовались Дж. М. Кейнс, П. Самуэльсон, Р. Мертон, Ф. Модильяни, М. Шоулз, Е. Фама и др. Однако, несмотря на серьёзное продвижение в данной области, вопрос построения моделей, адекватных реальным условиям, всё так же далёк от окончательного решения и требует продолжения работы по их изучению.

Срочную структуру широко применяют для анализа цен и доходности облигаций, используют при оценке справедливости рыночных прогнозов. Кривые срочной структуры процентных ставок чрезвычайно важны при изучении процессов, происходящих в экономической сфере, поэтому они нуждаются в адекватных моделях оценки. В действительности процентные ставки по кредитам и займам в произвольный момент времени не наблюдаемы. А поскольку это так, то остаётся только смоделировать их, опираясь на имеющиеся данные по государственным или корпоративным облигациям, по другим доступным финансовым инструментам, исходя из поставленной перед исследователем задачи.

Все модели имеют свои достоинства и недостатки, поэтому специалисту необходимо определить цель исследования и под неё подбирать модель, учитывая её свойства. Модели рассматриваются в той хронологии, в какой они были разработаны. Каждая последующая модель из каждого класса была призвана устранить недостатки предыдущей версии, но это не всегда удавалось, и в новой модели или усиливались слабые стороны предшествующей, или появлялись новые.

Предложен алгоритм выбора модели, исходя из её основных свойств, которые могут стать наиболее важными для успешного решения поставленной перед специалистом проблемы.
Contemporary realities of communication ethics in the educational space
Authors: Ermolova Т.V. , Litvinov A.V. , Savitskaya N.V. , Krukovskaya O.A.
Published: October 2021

The article discusses the current ideas of the foreign scientific school about the specificity of the ethical filling of the educational space in conditions of multiple uncertainty. The destructive factors of modern times, including the pandemic, have created a living environment of increased moral and ethical complexity and new challenges to the education system. Ethical changes in the educational space, both traditionally present and new, lead to a decrease in the quality of education, dehumanizing and dissocializing the student who finds himself in impelled isolation. The working hypothesis of the review is that the spatial separation of participants in the educational process is especially dangerous for the ethical integrity of the educational environment. The problems of ethical deficits of the teacher and the student are deduced: bullying, destructive leadership, academic dishonesty (cheating). The article regards several conditions for creating an ethically normalized learning process that might appear helpful in distance learning of students and regular utilization of social networks.
Principal approaches to the classification of science in national, international, and European law. Part II. Subject (industry) classification. Classification by other criteria
Authors: Tchetverikov A. O.
Published: October 2021

Part II of the article deals with the approaches of modern legal sustems to the subject-matter (disciplinary) classification of science, as well as with the additional classification criteria such as mode of financing of scientific research and its importance for State and society which are employed in several legal systems.

Basing on practical examples, author demonstrates that, despite the equivalence of the main classification criteria, the modern law lack uniform approaches to subject-matter (disciplinary) classification of science. This state of play characterizes both inter-state context (different scientific disciplines in different legal systems) and intra-state context (different approaches in different legal sources of the same country).

Author concludes in favour of consideration of a legal recognition as a specific category of scientific research those conducted by means of megascience-facilities. The above-mentioned category can be further divided into subcategories corresponding to various types of megascience-facilities such as light-sources and neutron sources.

Objectives: In recent years, the harm of smoking has attracted more and more public attention. Creating a healthy smoke-free environment has been widely favored and supported by the public. Smokeless environment has a certain positive effect on the rehabilitation of dementia patients.
Sustained smoking cessation is associated with significantly decreased the future prevalence of dementia. Therefore, hospitals often establish a special organizational structure and management model for tobacco control, and carry out training and assessment for all staff. The nursing group
also took it as the basic nursing standard. The 2019 disease pandemic has posed unique health threats to people living with dementia (PLWD). Therefore, a strict smoke-free environment is more necessary for the nursing group. One of the key challenges is scaling up long-term care services to
meet the needs of the rapidly growing population of PLWD in developing countries. The aim of the study is to explore the care service needs, utilization and build an essential care service package (ECSP) for PLWD under the disease pandemic in China. Methods: From July 2018 to October 2019,
a total of 1255 elderly with dementia in six cities in China by a cluster sampling were investigated with the self-designed questionnaire. Care service needs and utilization for PLWD with different levels of cognitive impairment were summarized. Results: The ECSP for PLWD was composed of 30
service items (7 for core care) in order to guarantee that all PLWD enjoy equal care services, basing on public financing and implementing strategies and taking China's situations into account. The selection plan for ECSP at different levels is designed as 'General Care Services + Selective
Care Services ', in which respective service items for low, mid, and high-level care for PLWD are 7+3, 7+6, and 7+10, and requires 151.41 hours, 201.88 hours, and 252.35 hours per month, respectively. Conclusion: The present study provides the first large-scale data on care service needs and
utilization for PLWD in mainland China. The ECSP for PLWD based on the needs advanced in the paper was a practicable and effective quantitative management means that deserves a large-scale application. Some safeguard mechanisms and operational implementing pathways of ECSP for PLWD during
and after the disease pandemic in China are proposed.

Background: Perilla seeds are known to cause immediate allergic reactions. However, reports on perilla seed allergies are limited to a few case reports worldwide, and there is currently no diagnostic test for such allergies. Objective: Our objective was to analyze the clinical and immunological characteristics of perilla seed allergy and to identify allergens for the development of diagnostic methods. Methods: Twenty-one children with clinical perilla seed allergy were enrolled from two tertiary hospitals between September 2016 and June 2019. Using perilla seed extract, we developed a skin prick test (SPT) reagent and an IgE enzyme-linked immunosorbent assay (ELISA) for perilla seed allergy diagnosis. IgE immunoblotting was performed for identifying putative allergenic components, and amino acid composition analysis was performed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Results: The median age of children with perilla seed allergy was 3 years; the proportion of children with anaphylaxis was 28.6%. Perilla seed SPT was performed in 15 of 21 children, all of whom tested positive. On ELISA, 85.7% of children tested positive for perilla seed-specific IgE. Proteins with molecular weights of 50, 31–35, and 14–16 kDa showed binding with the sera of >50% of children with perilla seed allergy. LC-MS/MS analysis of these three protein fractions indicated 8 putative proteins, including perilla oleosin (Accession No. 9963891), to be allergens. Conclusion: This study documented the clinical characteristics and immunological profiles of 21 children with perilla seed allergy. Our results suggest that oleosin is one of the major allergens in perilla seeds.

Abstract. The purpose of the article is to identify the main factors that constrain lending to enterprises of the agro-industrial complex of Ukraine, to suggest ways to improve their lending system. A systematic approach was chosen as the methodological basis of the study, which provides for a comprehensive study of the bank lending system of the agro-industrial complex. Historical and structural-functional approaches were also used in its analysis. Methods of comparative analysis were used to consider some problems of bank lending to the agro-industrial complex. Of the general scientific methods in this study, methods of analysis and synthesis, induction and deduction were used. The article examines the dynamics and structure of loans to the agro-industrial complex in Ukraine for 2015—2020; the dynamics of interest rates on loans to the agro-industrial complex and the dynamics of agricultural production by UAH 1. credit provision of the agro-industrial complex in Ukraine for 2015—2020. During the analyzed period, these indicators increase or decrease proportionally, as evidenced by the importance of the efficiency of credit support of the agar sector. In 2020, the efficiency of credit provision of the agricultural sector amounted to UAH 11.64, which is UAH 0.4 more than in 2015. The analysis revealed that the agro-industrial complex today has a high need for financial resources. The characteristic of the main problems of the mechanism of crediting of an agro-industrial complex is given. The need to ensure the availability of bank loans has been identified. Stimulating investment lending to agricultural enterprises will have a positive impact on the development of the industry, as well as improve the existing economic situation of rural residents. High demand for credit resources from agricultural producers, the current state and dynamics of lending to the agro-industrial complex in Ukraine allow us to conclude that it is necessary to improve the mechanism of bank loans, develop effective credit products for the agro-industrial complex and strengthen state support for agricultural lending. Keywords: credit, banks, enterprises of the agro-industrial complex, credit programs for the agro-industrial complex. JEL Classification G21, Q14 Formulas: 0; fig.: 3; tabl.: 1; bibl.: 15.

Abstract. The article deals with the analysis of economic and legal aspects of rational nature management as a component of ecological safety. The ecological problems of the current state of the natural environment of the country are analyzed. It is stated that environmental security is one of the most important components of national security of Ukraine, which depends on the rational use and reproduction of natural resources. The concept of rational nature management is formulated, the concept consists in the sphere of production and scientific activity aimed at the study, development, protection and transformation of nature in order to ensure favorable conditions for human life. It was found out that the rational use of nature necessarily involves the economic and legal component, which lies in getting the most out of economic and other activities in the use of natural resources at economically reasonable costs. The concept of economic and legal mechanism of nature management is defined, which is enshrined in the system of economic and legal measures, incentives and other regulators aimed at ensuring environmental protection, environmental safety and organization of rational nature management and is based on the concept of payment for the use of natural resources, introduction of economic and legal responsibility. Proposals have been formulated as for the implementationof additional measures of fiscal regulationof nature use by Ukraine, granting tax benefits to enterprises implementing relevant environmental protection programs, insurance of environmental risks.

Published: October 2021

In contexts of protracted violent conflict, school environments play a key role in children’s psychological, social, and emotional wellbeing. Research by the REALISE education project in the Democratic Republic of the Congo (DRC) provides a better understanding of how violent conflict penetrates schools; the relationship between school staff, students, parents, and the local community; and the role of children’s social entourage. It identifies key considerations for education projects operating in these contexts and how they can best support the wellbeing of children, including those who are extremely isolated or experience marginalisation on the basis of gender or minority status.
