The article is devoted to the study of the peculiarities of the Soviet national policy in the regions of the North, Siberia and the Far East. An important issue is the consideration of the actions of the Soviet government in relation to indigenous small-numbered peoples. The radical change of the state system led to the development of a new system of interethnic relations, new systems of interaction with the indigenous peoples of the North, Siberia and the Far East. New social technologies are being introduced in the fields of education, agriculture and national policy in general; local self- government bodies are being created. National policy is undergoing multiple changes, as is the history of the USSR as a whole. A special period is the war and post-war period. There are widespread changes in the economic life and culture of the peoples, their transition to a more sedentary lifestyle and, as a result, the loss of some skills of the traditional nomadic lifestyle.

With the use of special technological techniques (layer-by-layer spraying, air cooling and substrate temperature control), the technologically complex problem of applying plasma coatings of increased thickness with high adhesive strength has been solved. The difficulty of solving this problem is due to the occurrence of micro-stresses in the coating during spraying, the difference in the values of the coefficient of thermal expansion of the substrate and the coating, the accompanying heating during plasma treatment, as well as the warping of thin-walled parts during spraying. The regularities of the formation of a coating of zirconium dioxide with a thickness of ~1 mm during high-energy plasma spraying of a powder mixture ZrO2 +7% Y2O3 with a spherical morphology of particles have been studied. The structural-phase state of the coating is investigated. It is established that with this method of spraying, a layered hierarchy of the coating is formed with a columnar shape of zirconium dioxide grains in the interlayers. The effect of the plasma flow stimulates the partial phase transformation of the tetragonal phase T-ZrO2 into the cubic K-ZrO2. To study the adhesive strength of the coating, different methods were used: scratch test, Rockwell test and low-cycle fatigue tests. The high adhesive strength of the adhesion of the investigated coating to the substrate is shown since no detachment from the substrate occurred during any type of testing. In sclerometry, the cohesive mechanism of destruction due to microscopes prevails, affecting only the surface layers (5–10 microns thick) of the coating. The Rockwell test demonstrated the best crack resistance score and a sufficiently high plasticity of the coating. Cyclic vibration tests based on 250,000 cycles showed that microcracks are formed at the boundary with the sublayer. The coating of increased thickness can be used both for protection against high-temperature exposure and against mechanical wear of parts in power and aviation engineering.
THERMAL SIMULATIONS OF CONTACTING SOLIDS WITH CONTACT ENERGY RELEASE
Authors: Seryakov Yu.D. , Glazunov V.A.
Published: November 2021

The paper describes a numerical model simulating thermal conditions of contacting solids considering heat release in the contact region. The finite-volume model is implemented in the Logos Heat digital product within the Logos software package. Logos Heat serves for numerical simulations of heat transfer processes in solids and in air gaps without convective heat transfer. Its methods and algorithms enable thermal simulations of three-dimensional and two-dimensional (including axisymmetric) structures under steady and unsteady conditions using nonconformal mesh models considering contact energy release.

We selected and considered the most common ways to determine the heat partition coefficient for the energy released by two solids being at rest or in sliding contact. The methods and algorithms incorporated in the numerical scheme of the Logos Heat product to consider the contact energy release were assessed using a case with a known exact solution and numerical data reported in.

The analysis of the calculated data shows that the maximum error does not exceed 0.1% for the resting model and 8% for the sliding-contact model, which indicates that the methods and algorithms are appropriate for such simulations. However, it should be noted that, within the Logos Heat numerical scheme, the solution calculated by Charron's formula introduces an error, which is one order higher than the error associated with the temperature conduction method, and creates a temperature discontinuity at the contact.
DESIGN OF THE BOUNDARIES OF THE STABILITY REGIONS THE STATIONARY ROTATION MODE OF A ROTARY SYSTEM WITH A LIQUID, THE AXLE OF WHICH IS LOCATED IN ANISOTROPIC FIXINGS
Authors: Derendyaev D.N. , Derendyaev N.V.
Published: November 2021

Earlier, the authors generalized the original method for studying the stability of stationary rotation of rotor systems containing a viscous incompressible fluid, the axis of which is located in isotropic anchors, in the case when the viscoelastic anchors of the axis of the rotor system are anisotropic. The generalization is based on two theorems that say that finding the stability conditions of such systems is associated with the possibility of elliptical precession-type motion, and with such motion there is a special non-inertial reference frame in which the hydrodynamic elements of the system periodically change in time.

The study of such movements allows us to construct the boundaries of regions with different degrees of instability, in particular, the boundaries of the stability regions of the stationary rotation regime in the parameter space of the problem.

The boundaries of the stability regions are constructed for cases when the anchoring of the rotor axis is anisotropic. In the space of the anchorage parameters, a parametrically defined D-curve is obtained as a function of the dimensionless frequency of the rotor precession. The two most interesting cases are considered – anisotropic stiffness of anchors (damping is isotropic in this case) and the opposite situation: isotropic stiffness of anchors with anisotropic damping. The obtained results are compared with the known results for the case of isotropic anchoring of the rotor axis.

It is shown that the anisotropy of anchors, which is always present in real rotary systems due to the imperfection of technologies for the production of anchors, does not lead to negative effects. Moreover, using the obtained D-curves, it is possible to obtain technological tolerances for the production of fasteners, using what is known as the permissible deviation of the stiffness or damping value along the axes.

The article considers the essence and features of state regulation of land sales in Ukraine, it substantiates the need for a preparatory process for this work. The tools offered in this work in the economic space of our country are tested at such important for Ukraine's economy enterprises as Ukrtelecom and Ukrzaliznytsia, which have significant land resources, all technological processes of full range of works without which the sale of land is not advisable. It should be determined that land is real estate, which is taken into account on the balance sheet of the enterprise, is a business entity and is regulated by the requirements of applicable regulations, because the intangible assets of the enterprise are a very heterogeneous set. Therefore, users of financial statements, especially marketers, are interested in information about their composition to build an effective development strategy. It is concluded that for the formation of a marketing system of land management it is necessary to: determine and register the land plot (determine the property rights; analyze legal documents and accounting system; perform an inventory of both land and rights to it - rights to intangible asset).

Authors conducted review and analysis of regulatory and legal support of the inventory procedure, as a part of an effective marketing inventory, which still remains an understudied procedure because, normatively, was not provided by regulations. A clear system of land inventory, registration, and timely analysis will reduce risks that cannot be completely eliminated. Paper concludes with the list of works on reconciliation of inventory results with data of technical passports issued by BTI, which should be the basis for the formation of the List of real estate and rights to them, and error prevention, which is the basis for the formation of an effective land management system.
Synthesis of Arts in Soviet Architecture: stages of development, main directions, causes of their occurrence
Authors: Bachynska Liudmyla
Published: November 2021

The history of the Soviet Union, its socio-economic, socio-political and socio-cultural life is unique in comparison with other countries. The USSR was created on the model of social development, expressed by European and Russian Utopian socialists and was grounded in the classics of Marxism-Leninism. So, the system of government, economic conditions and cultural activities of a society built on the hegemony of the proletariat was a long-running social experiment that conditioned the life of the Soviet people and influenced other countries as well. The experiment of a country with total state property envisaged that the party leadership assumed responsibility for defining all spheres of political life - both internal and interstate relations - and inevitably formed unified programs of cultural activity and social development, managed them, and financed and tightly controlled their implementation. The Soviet people, the so-called "working masses", were forced to live and act under uniform rules. Depending on the planning of the political, economic and social life of the party leadership throughout the existence of the USSR, the country went through several stages, which differed in the directions of forming an architectural and urban planning environment that had to meet the tasks of state and ideological character. Familiarizing yourself with this unique experience and finding the reasons for its formation is important for understanding the trends of social development in the twentieth century.
One approach to the axisymmetric problem of impact of fine shells of the S.P. Timoshenko type on elastic half-space
Authors: Bogdanov Vladislav
Published: November 2021

Refined model of S.P. Timoshenko makes it possible to consider the shear and the inertia rotation of the transverse section of the shell. Disturbances spread in the shells of S.P. Timoshenko type with finite speed. Therefore, to study the dynamics of propagation of wave processes in the fine shells of S.P. Timoshenko type is an important aspect as well as it is important to investigate a wave processes of the impact, shock in elastic foundation in which a striker is penetrating. The method of the outcoming dynamics problems to solve an infinite system of integral equations Volterra of the second kind and the convergence of this solution are well studied. Such approach has been successfully used for cases of the investigation of problems of the impact a hard bodies and an elastic fine shells of the Kirchhoff-Love type on elastic a half-space and a layer. In this paper an attempt is made to solve the axisymmetric problem of the impact of an elastic fine spheric shell of the S.P. Timoshenko type on an elastic half-space using the method of the outcoming dynamics problems to solve an infinite system of integral equations Volterra of the second kind. It is shown that this approach is not acceptable for investigated in this paper axisymmetric problem. The discretization using the Gregory methods for numerical integration and Adams for solving the Cauchy problem of the reduced infinite system of Volterra equations of the second kind results in a poorly defined system of linear algebraic equations: as the size of reduction increases the determinant of such a system to aim at infinity. This technique does not allow to solve plane and axisymmetric problems of dynamics for fine shells of the S.P. Timoshenko type and elastic bodies. This shows the limitations of this approach and leads to the feasibility of developing other mathematical approaches and models. It should be noted that to calibrate the computational process in the elastoplastic formulation at the elastic stage, it is convenient and expedient to use the technique of the outcoming dynamics problems to solve an infinite system of integral equations Volterra of the second kind.
Investigation of mechanical properties and crack resistance parameters of steel reinforcements of reinforced concrete structures of long-term special term
Authors: Kulikov Petro , Makarenko Yulia , Khoruzhiy Victor , Makarenko Valeriy
Published: November 2021

It is known that the fatigue process begins with the plastic deformation of the surface layers of the metal fittings. Moreover, the displacement of dislocations under conditions of re-alternating loads is observed at loads below the elastic limit of the metal. The rate of local plastic deformation during cyclic deformation is several orders of magnitude higher than the rate of deformation under static loading. Dislocation slip begins in grains with a favorable orientation near stress concentrators. As the number of cycles in the surface layers increases, the density of dislocations and the number of vacancies increases. When the base number of NR cycles is reached, a surface reinforced layer of metal with a large number of germinal cracks is formed, the size of which does not reach a critical value. Increasing the number of cycles cannot cause further development of fracture in such a layer. Only when the stresses exceed the endurance limit of the crack reach a critical length, after which the process of their discharge into the main crack begins with the spread of the latter. The results of experimental studies indicate a strong effect of diffusion hydrogen on static and cyclic parameters of crack resistance. It was found that with increasing flooding, especially when the hydrogen content exceeds 5 cm3/100g, both static strength and long-term strength (fatigue) decrease sharply. Moreover, for these areas of hydrogen solution in reinforcing steel is characterized by a viscous nature of fracture, while for heavily flooded reinforcement (from 5 to 12 cm3/100g is characterized by brittle fracture by the mechanism of microfission in the hardened (martensite or troostite structure). allowed to determine the optimal hydrogen content in reinforcing steel (3…5 cm3 /100g), the excess of which will reduce the crack resistance of reinforcement during long-term operation, especially in corrosive environments. The results of the research confirm the above data. bainite structure y sharply reduces the crack resistance of reinforcing steel, which makes it impossible to use in the manufacture of reinforcement involved in reinforced concrete structures designed for long-term operation (more than 50…60 years). Thus, the obtained diagram can be recommended to designers of reinforced concrete structures for hydraulic purposes, as it greatly facilitates the reasonable choice of reinforcement in the development of reinforced concrete structures for responsible and long-term use.

Aim: to analyze the anterolateral thigh flap use to eliminate oncological defects in the head and neck area with an emphasis on the flap raising characteristics. Patients and Methods: 146 patients aged 33 to 80 y.o. underwent the surgery in the period from 2011 to 2020. Single-stage reconstruction (143 surgeries) of the various parts of the upper aerodigestive tract (142 surgeries) was mainly performed. Most of the patients (130 cases) underwent the surgery at the first stage of antitumor treatment. In 13 cases, surgical treatment was performed concerning tumor recurrences; in 3 — delayed secondary reconstruction was performed. Flap raising was conducted according to the generally accepted method without the use of preoperative mapping of perforators. The surgery protocols and medical histories were analyzed for the patterns of vascular anatomy and the number and nature of flap-related complications. Results: typical vascular anatomy was noted in 115 cases (78.8%). When raising 31 flaps, anatomical deviations of the course and origin of cutaneous perforators were noted, which can be divided into 4 types: oblique branch anomaly (11 cases), upper type of anterolateral thigh flap (11), anteromedial thigh flap (6) and the rectus femoris muscle (3), while the latter type is rarely mentioned in the literature. The descending branch was the source of cutaneous perforator in 133 cases (91.1%). In 6 cases (3.9%), unfavourable vascular anatomy forced the use of a contralateral hip as a donor area. The reason for the failure in one of these cases was hypoplasia of the descending branch. The primary wound closure of the hip was performed in 143 patients (97.9%), even though the flap width exceeded 8 cm in 7 cases. Postoperative mortality was 1.4%. The main complications associated with the flap included: total flap loss (9 cases; 6.2%), partial necrosis (6; 4.1%) and donor wound complications (8; 5.5%). Conclusion: the anterolateral thigh flap is an excellent plastic material, however, it requires knowledge of the vascular anatomy characteristics of adjacent hip zones.

Background: malignancies are a critical issue of healthcare worldwide and rank second among leading causes of death. Gastrointestinal (GI) cancer morbidity and mortality are different across national populations and even territories of one country. A set of factors affect GI cancer prevalence, e.g., social-economic, climatic geographical, ecological, behavioral, hereditary factors of the living environment, etc. Aim: was to analyze the rate of GI cancers among habitants of northern regions of Russia and its changes over five years and compare these data to the Russian population. Materials and Methods: official statistical data of the P.A. Hertsen Moscow Oncology Research Institute — Branch of the National Medical Research Radiological Centre (2016–2019) were used. In addition, published data on GI malignancies indexed in Medline, PubMed, Web of Science, Scopus, and Google Scholar databases were reviewed. Results: a higher rate of GI cancers among populations of northern regions of Russia (more remarkable than in Russia) was reported. Standardized incidence varied from 4.84±0.63 in the Murmansk Region to 12.72±4.64 in the Chukotka autonomous region. The exclusions were the Krasnoyarsk region and Khanty-Mansy autonomous region. In these regions, the incidence was similar to all-Russian incidence. In men, GI malignancies develop several years earlier than in women, i.e., the difference varies between 1.5 years (colon cancer) and 5.6 years (pancreatic cancer). The leading malignancies in Russia are gastric cancer and colon cancer. Conclusion: cancer prevalence and risk factors in populations of northern regions of Russia provide novel modalities to improve preventive and treatment strategies for malignancies.

Luminal B (HER2-negative) breast cancer is considered the most common type. The consistent prescription of hormone therapy lines for disseminated estrogen receptor-positive (ER+) HER2-negative breast cancer allows us to consider this variant of the tumor as a chronic disease with long-term oral therapy. Oral chemotherapy can improve the life quality of patients while ensuring the high efficiency of the treatment. If there is a standard for the first lines of hormone therapy, the optimal chemotherapy regimen of line 1 is not established and is determined individually in each case. The authors note that it is necessary to rely on the expected toxicity of therapy and the toxicity of previous treatment, as well as take into account the patient’s willingness to visit the clinic for intravenous infusions. The article presents a clinical case concerning a patient suffering from disseminated ER+ HER2-negative breast cancer. This clinical case shows how it is possible to postpone the prescription of intravenous chemotherapy as much as possible (with the rational use of hormone therapy regimens, as well as oral chemotherapy), thereby improving the patient’s life quality. In the context of the COVID-19 pandemic, which involves limiting visits to medical institutions, oral chemotherapy can be considered as the therapy of choice for such patients.

Authors:   Duke Kunshan University, Burns Allan
Published: November 2021

Anthropologists have worked in legal arenas as experts on civil, criminal, and asylum cases throughout the history of the discipline. Today expert witnesses give opinions on the conditions of countries where immigrants flee, and that work includes ethnographic interviewing, research into the causes of political and social violence, and appearing in court through written affidavits and personal testimony. Expert testimony today includes helping in the defense of people fleeing intimate partner violence, persecution based on sexual orientation, threats and violence by gangs, and those whose political opinions put them at risk. Immigrants in the United States face institutional culture shock, structural violence, and criminalization of their lives. Case studies of immigration, civil, and criminal cases illustrate how theory and practice intersect in the harsh light of court cases.

Introduction. Achieving a qualitatively new state of society largely depends on the formation of the creative potential of young specialists capable of transforming, developing and implementing original solutions to professional and personal tasks, in connection with which the development of mechanisms for the formation of a professional capable of transforming the world and oneself seems to be very relevant. The authors propose to organize joint activities to solve creative problems in the form of a system of training sessions for the development of the creative potential of the personality of students. Materials and methods. The study involved 200 junior students of Volgograd universities, boys and girls aged 18-20 years, humanitarian and natural science areas of training. The main statistical calculations were performed using the analysis of nonparametric data using the chi-square test for the analysis of frequency differences, as well as using the statistical Mann-Whitney U test. The results of the study. Statistically significant significant differences were revealed according to the Mann-Whitney U-test (at p <0.05) between the values of the scales of the experimental and control groups of students according to the following indicators: the index of verbal originality (p = 0.033); the index of verbal uniqueness (p = 0.026); the number of responses produced (p = 0.008); striving for creativity and creativity (p = 0.026), expert assessment of creative potential (p = 0.041). The diagnostic indicators allowed us to conclude that students in the humanitarian areas of training more often demonstrate a high level of originality and productivity of verbal constructions, they are characterized by the spontaneity inherent in a self-actualizing personality. Students of natural science areas of training are more often looking for new ways of thinking, they have a more pronounced desire for self-development. Conclusions. Purposeful, organized joint activities in the form of training aimed at the formation of knowledge, skills and abilities of collective solution of creative problems, has shown effectiveness in solving the problem of developing the creative potential of future specialists.

Introduction. Universities are looking for effective ways to recruit foreign citizens, but many factors influence the choice of university. The climatic conditions and geographic location of the region in which distant universities have to work and which they cannot change usually not considered as a significant factor. The purpose of the study is to identify the positive and negative aspects of studying in a remote university located in a region with difficult climatic conditions and the most effective methods of recruitment of foreign students. Materials and methods. The results of a survey of foreign students of the M.K. Ammosov North-Eastern Federal University were used as materials for the study. The survey involved 335 students enrolled in main professional educational programs, exchange programs, students of preparatory courses and courses of the Russian language. Results. The majority of respondents named the quality of education (21%), attitude towards foreigners (18%), the work of teachers (16%) and the infrastructure of the university (13%) as the advantages of studying. Most of the respondents (53%) did not indicate any disadvantages of studying at the university, 11% mentioned the geographical location of NEFU and 8% pointed climatic conditions of the region. The respondents first learned about the university from friends (25%), from the internet (23%) and Rossotrudnichestvo offices in the countries (14%). The results of the survey showed that 35% of students plan to return home or leave for another country. The dispersion of this answer across countries showed that representatives of almost every country are planning to go home or to another country, regardless of the period of study passed. 29% of the respondents would like to stay here and work in Yakutia after graduation. The poll showed that both representatives of the CIS countries and non-CIS countries wish to stay in Yakutia to work. Conclusion. Increasing university awareness through social media and partnerships with educational organizations, using various recruiting methods and involving students themselves in this process are key ways to increase the number of students.

Introduction. In recent years, the problem of training a new generation of mathematics teachers who have fundamental mathematical knowledge in combination with formed methodological competence and fluency in digital technologies has become topical. The purpose of the article is to present a scientifically based system for training future mathematics teachers, created at Donetsk National University, based on a comprehensive program for managing the project and heuristic activities of students for their productive work in a modern school. Methods. The study involved 125 people studying at Donetsk National University (65 students of the direction of training "Pedagogical education" (Profile: mathematics and computer science) – an experimental group, 60 people of the direction of training "Mathematics" – a control group). The effectiveness of a comprehensive program for managing students' project and heuristic activities was assessed according to three criteria: heuristic and didactic (HD); methodological and mathematical (MM); project and activity (PA). The meters selected: author's texts of control papers with heuristic tasks and computer testing systems (for HD and MM criteria), assignments for the development of author's educational projects using IT, students' term papers and theses (for PA criterion). To analyze the effectiveness of the complex program, the Student's t-test was used. Results. During the experiment, it was revealed that for each criterion, the average values of their indicators (in fractions of one) in the experimental group increased significantly. For the HD criterion, the level of heuristic skills formation among students of the experimental group increased from 0.51 to 0.65, for the MM criterion, the levels of mathematical and methodological competence formation increased from 0.67 to 0.753, for the PA criterion, the level of mastering the methods of project activities changed from 0.57 to 0.756. The empirical value of the statistics of the Student's criterion t = 2 (p < 0,05) obtained in the assessment procedure proves that changes in the results of training are not random, which means that the proposed comprehensive program is more effective than the traditional one. Conclusions. The preparation of a future mathematics teacher based on a comprehensive program for managing the project and heuristic activities of students ensures the formation of heuristic and didactic, methodical and mathematical, project components of the teacher's professional activity, which are necessary for teaching schoolchildren of the Z generation.

Introduction. For foreign students of Russian universities, the Russian language serves as a means of obtaining higher professional education. In this regard, one of the priority tasks of improving the quality of training specialists for foreign countries is the language training of foreign citizens in the Russian language for special purposes. Materials and methods. 126 foreign students of the first year of technical specialties of Peter the Great St. Petersburg Polytechnic University participated in the survey. The results of the study. The survey made it possible to identify the difficulties that foreign students have in the process of learning the language of their specialty and communicating in Russian in the educational environment of the university of the Russian Federation. Among the main difficulties affecting successful communication, foreign students noted communication with teachers of specialized disciplines (46.1%) and with employees of the dean's office (40.4%). The greatest difficulties in the training sessions are caused by understanding the lecture material (49.4%) and understanding the tasks for laboratory work (46.1%). Among the difficulties directly related to the study of the Russian language of the future specialty, the following types of tasks were noted: forming sentences (43.85%), grammar tasks (42.7%), writing dictations (36%). Discussion of the results. The results of the survey allow us to place methodological accents in the preparation of curricula, the creation of modern textbooks and tutorials; to take into account the communicative needs of foreign students who are starting to study on higher professional education programs in Russian technical universities; to implement the principle of continuity and interdisciplinary connections in the formation of the educational route of foreign students. Conclusion. Effective organization of teaching foreign students in the Russian language for special purposes contributes to improving the quality of training of highly qualified competitive specialists for foreign countries and the growth of the international authority of Russian higher professional education.

Introduction. The structure of the concept of "economic activity", in addition to the specific content related to empirical reality, includes philosophical content related to the scientific picture of the world. Hence the problem arises: in the process of the historical development of economic science, the semantic inertia of past ideas about the world and man, manifested in language constructions, remains in the concept of "economic activity". These changes should be taken into account in the educational process, since the concept of "economic activity" is one of the didactic units. Materials and methods. The research material is reference and educational literature, as well as economic classics (works of Aristotle, etc.). The article uses methods of philosophical analysis, primarily systematic and comparative. The systematic method allows us to identify the determinants of the philosophical content of the concept of "economic activity" associated with the scientific picture of the world. The comparative method allows us to assess the change in the philosophical content of the concept in the course of its historical development, to consider the commensurability of new and traditional meanings. The results of the study. The solution of the problem of the philosophical content of the concept of "economic activity" requires the elimination of the ideological heritage of past epochs, in particular, the ancient one (naturally, taking into account the historical value of this heritage). It is important to modernize the philosophical content of the concept of "economic activity" within the framework of the modern scientific picture of the world. In the latter, the understanding of economic activity is correct as not one of the types, but as one of the aspects of human activity, evaluating this activity from the point of view of value. Discussion and conclusion. The implementation of these theoretical and methodological procedures is expedient. The change of scientific pictures of the world, which occurs in the course of the development of science, leads to significant changes in the philosophical content of the conceptual apparatus of economic science. If these changes are not taken into account in the educational and reference literature, this negatively affects the quality of the economist's training.

Problem and purpose. Digital transformation is a key trend of the economic development. Russia still lags behind countries leading in the digitalization. Insufficient development of relevant skills is one of the constraints. The share of Generation Z (born in 1996 and later) will achieve 25% of the labor force by 2025. This statement emphasizes the need to develop competencies for the younger generation that respond to the requirements of the digital economy. The purpose of the study is to assess the contribution of the Russian higher education system to the reproduction of the juvenile potential of the economy in the context of its digital transformation, to identify constraining factors and develop basic recommendations aimed at eliminating them. Materials and methods. The study is based on the use of economic and mathematical methods, including factorial, correlation and regression analysis. The dynamic series of indicators characterizing the state of the investigated sphere in 2001–2019 have been studied. For analytical data processing, the software capabilities of the Statistica package are used. Research results. The author's system of indicators has been developed, which makes it possible to assess the role and capabilities of the higher education system for the reproduction of the juvenile potential of the digital economy – 18 indicators characterizing the financial and material-technical, intellectual, educational potential, the coverage of young people with higher education programs, the effectiveness system of higher education. The formula for calculating the integral indicator of the juvenile potential is mathematically substantiated. Modeling of the dependence of the integral indicator on a set of influencing factors has shown that with an increase in the number of teaching staff by 1 sigma, the integral indicator of juvenile potential will on average increase by 1.758 sigma while fixing other exogenous variables at a constant average level; with an increase in the number of personal computers used for educational purposes by 1000 students per 1 sigma, the integral indicator of juvenile potential will, on average, increase by 1.078 sigma, while fixing other exogenous variables at a constant average level. Discussion and conclusion. The study showed that for the formation of the juvenile potential of the digital economy of the Russian Federation, it is necessary to develop the human resources of higher education and its digital environment. To solve the designated tasks, a system of measures has been developed.

One major problem faced by network users is an attack on the security of the network especially if the network is vulnerable due to poor security policies. Network security is largely an exercise to protect not only the network itself but most importantly, the data. This exercise involves hardware and software technology. Secure and effective access management falls under the purview of network security. It focuses on threats both internally and externally, intending to protect and stop the threats from entering or spreading into the network. A specialized collection of physical devices, such as routers, firewalls, and anti-malware tools, is required to address and ensure a secure network. Almost all agencies and businesses employ highly qualified information security analysts to execute security policies and validate the policies’ effectiveness on regular basis. This research paper presents a significant and flexible way of providing centralized log analysis between network devices. Moreover, this paper proposes a novel method for compiling and displaying all potential threats and alert information in a single dashboard using a deep learning approach for campus network infrastructure.

The most important factor to ensure forest regrowth strongly relies on minimizing damage as well as maintaining an adequate quantity and quality of residual stands. Currently, most of the Malaysian concessions are applying the Selective Management System (SMS). The SMS had been introduced about 40 years ago and various studies discovered that it contributes a negative impact on the forest. Thus, revision and adoption of an appropriate harvesting method are required. The main objective of this study is to propose a new method that promotes forest regrowth and reduces damages due to logging activities for Sustainable Forest Management (SFM). The two primary elements introduce in this new method are 1) to determine the minimum damage cost/value to the residual trees according to tree felling direction and 2) on the division of logging area into clusters where only certain clusters will be affected in a logging operation and the rest are conserved. The overall results of this study proven that the analysis of potential logged value, productions, damage value, and damage volume by dividing forest into clusters able to minimize damage and maintain forest regeneration.
