Authors: Kravcheniuk Rostyslav , Stadnyk Ihor
Published: September 2024

In connection with the deterioration of the health of the population of Ukraine, the primary task should be to enrich the usual diet with products of functional purpose and to add natural biologically active additives that contribute to the removal of radionuclides, toxins, normalization of the body's systems and increased immunity. This work is devoted to the study of the process of beet processing and its further use in the bakery and confectionery industries. The refractometric method was used to determine the content of soluble solids. The content of trace elements was determined using the atomic adsorption method. When preparing kvass from table beets, additional raw materials were added: sprouted flax seeds, whey, yeast, viburnum powder, rye bread crackers. It was established that the variety of the Dutch selection Roket differs from the varieties Bordeaux 237 and Cylindra in terms of dry matter, organic acids, dyes and sugars. It is important to note that when improving kvass preparation technology, optimal fermentation conditions and dosing of additives are taken into account in order to maximize the shelf life of the product without losing its quality. In view of the increase in the number of genetic and complicated diseases, it is worth noting the introduction of specialized dietary programs, which are gaining more and more relevance. Such programs have been found to ensure food security and meet all essential nutrient needs. Considered the problem of the need for constant improvement of recipes of food products, study of new gluten-free alternatives and provision of access to high-quality gluten-free products. Studies have proven that the use of natural raw materials in the production of beet kvass is an effective means of improving its quality characteristics. Therefore, a promising direction in the production of flour products is the improvement of the recipe of the existing assortment due to the use of natural plant components of increased biological value. Kvass from table beet can be a source of natural biologically active substances (BAR). Table beets have a rich chemical composition. The nutritional value of beets is additionally balanced by the content of sugars and acids (citric and oxalic), the content of organic substances, minerals and vitamins. The production of bakery products using kvass from table beet as a natural food additive is relevant today.

Published: September 2024

The need for consumption of fruit products, in particular sweet cherries and cherries, is growing every year in Ukraine. This is driven by national traditions, stakeholder needs, and the population's demand for healthy eating. Cherries are a nutritious fruit that contains such functional ingredients as essential amino acids, vitamins, minerals, dietary fiber, etc. Unfortunately, in terms
of long-term storage, cherries quickly lose their quality and have a short harvest and processing period. To increase the shelf life of products, it is advisable to develop and improve methods of storage and processing of cherries. Optimisation of chilling methods for cherries before storage increases the shelf life of fresh fruit and the suitability for fresh consumption. Improving the methods of chilling cherries will help to increase the demand for its fruits by all stakeholders in the European market.

The aim of the research was to establish the optimal concentration of acetic and lactic organic acids, which are included in the protective composition for processing cherry fruits, and to determine the level of daily losses of cherry fruits during hydrocooling while maintaining the global optimum point.

To establish an effective cooling method, fruit losses caused by diseases of microbiological origin and physiological disorders were determined. During storage, the effect of the concentrations of the protective composition on the indicators of weight loss and the average level of daily fruit loss was studied.

A regression model was built and the optimal values of the indicators were determined by stages: a regression model was built on the basis of experimental data and the global optimum point was determined on the basis of the model and a confidence interval for the optimum was built.

According to the results of the research, the lowest rate of daily fruit losses at the level of 0,117%-0,121% was recorded during hydrocooling of cherry fruits using organic compositions of lactic and acetic acids in the ratio of their components of 1,25-2,25:1,50-2,25 and 1,75-2,25% with the amount of acetic acid at 1,25%, respectively.

The regression analysis showed the optimal value of the average level of daily losses during storage of cherry fruits of the model variety ‘Vstrecha’ – 0,106% at the value of factors x1=2,217 and x2=1,966.

Wolfgang Streeck on the Origins of Capitalist Crisis
Authors: Sadian Samuel
Published: September 2024

Shortly after the financial crisis of 2008, Wolfgang Streeck emerged as a highly influential and ambitious critical theorist of capitalism and crisis. Streeck's crisis theory of capitalism is built around an account of neoliberal policy reform as a family of responses to economic upheavals that first emerged during the 1970s. Based on an analysis of four major shocks all occurring in that decade, I argue that Streeck's crisis theory is excessively economistic in its understanding of the crisis tendencies that first propelled neoliberal reform and insufficiently attentive to the global context of their emergence. Theorising the significance of this pivotal historical moment requires more attention to the conflictual entanglements between societies of the Global South and North in the context of decolonisation, war and revolution, and a more nuanced appreciation of the political context of economic reform.
Revisiting Badiou's Theory of the Political Subject
Authors: Rech Walter
Published: September 2024

This article argues that Alain Badiou's theory of the subject offers conceptual resources that help make sense of ordinary life-experiences of ‘evental moments’ and enable the critique of hypertrophic forms of political or corporate agency. The article identifies a set of ideas through which Badiou's philosophy contributes to much-needed emancipatory thinking today. As it investigates the notions of horlieu and the event, the article stresses that true political change requires the emancipation of the ‘quasi-totality’, something that ‘reactive’ political or corporate subjects would not be able to deliver. The piece emphasises that, for Badiou, universalist equality is the indispensable game-changer of politics, and that every single person can contribute to genuinely egalitarian projects. In Badiou's view, there are no meta-subjects and meta-events. Everyone can experience truth in their lives.

Levodopa-resistant parkinsonism developing after ventriculoperitoneal shunting for obstructive hydrocephalus and improving after endoscopic third ventriculostomy, with specific consideration of brainstem morphology: illustrative case
Authors: Morisue Yoshihiko , Osawa Shin-ichiro , Niizuma Kuniyasu , Kanno Shigenori , Suzuki Kyoko , Endo Hidenori
Published: September 2024

BACKGROUND

Parkinsonism has been reported in patients with obstructive hydrocephalus (OH) following ventriculoperitoneal shunting (VPS). While levodopa works well, some cases are drug resistant. A few case series have reported that endoscopic third ventriculostomy (ETV) is beneficial, though its mechanism remains unclear. The use of a pathophysiology-reflected marker can aid in the diagnosis and treatment strategy. The authors report a case of parkinsonism due to OH after VPS that improved after ETV in a patient taking levodopa, which was subsequently discontinued.

OBSERVATIONS

A 52-year-old man who had undergone VPS for OH caused by aqueductal stenosis with a tectal tumor presented with severe consciousness disturbance due to acute hydrocephalus and levodopa-refractory parkinsonism after multiple episodes of shunt malfunction. Magnetic resonance imaging showed an elevation of the floor of the third ventricle. ETV was performed to stabilize the pressure imbalance across the stenosis, and his parkinsonism symptoms improved after long-term rehabilitation, resulting in levodopa discontinuation. His pontomesencephalic angle, the angle between the anterior surface of the midbrain and upper surface of the pons in the midline of the sagittal plane, was significantly decreased.

LESSONS

The focus in such cases should be on the essence of the pathophysiology for improving the symptoms rather than on easy-to-understand indicators such as ventricle size.

Spontaneous asymptomatic common carotid artery dissection resembling a carotid web: illustrative case
Authors: Takahashi Toshihide , Yanaka Kiyoyuki , Aiyama Hitoshi , Saura Minami , Kajita Michihide , Takahashi Nobuyuki , Marushima Aiki , Matsumaru Yuji , Ishikawa Eiichi
Published: September 2024

BACKGROUND

Carotid artery dissection is a common cause of ischemic stroke, predominantly affecting the internal carotid artery, with rare involvement of the common carotid artery (CCA). The limited literature makes diagnosis and management challenging, particularly in asymptomatic patients. In this report, the authors present a unique case of spontaneous, asymptomatic CCA dissection that resembled a carotid web, shedding light on its clinical spectrum and management.

OBSERVATIONS

A 70-year-old man was diagnosed with an intimal flap in the left CCA. Although the findings resembled those of a carotid web, cerebral angiography confirmed the presence of an intimal flap and arterial wall irregularities indicative of vascular dissection. Endarterectomy successfully prevented the stroke, and the postoperative recovery was uneventful. Pathological examination confirmed the diagnosis of CCA dissection.

LESSONS

Spontaneous CCA dissection, though rare, presents significant diagnostic and therapeutic challenges. Because of morphological similarities, differentiating the diagnosis from a carotid web can be difficult. Available treatment strategies include antiplatelet therapy and surgical intervention. In this case, endarterectomy was chosen to avoid antithrombic treatment in anticipation of further invasive treatments for other conditions. The successful outcome highlights the potential as a treatment option, emphasizing the need for an individualized approach to each patient.

Authors: Harary Paul M , Hori Yusuke S , Persad Amit R. L , Tayag Armine , Ustrzynski Louisa , Emrich Sara C , Rahimy Elham , Park David J , Li Gordon , Chang Steven D
Published: September 2024

BACKGROUND

While genetic testing of tumors is commonly used to inform the selection of systemic therapies, there is limited evidence for the application of radiotherapy for brain cancer. Recent studies have shown that Kelch-like ECH-associated protein 1 (KEAP1), a key regulator of cellular responses to oxidative and electrophilic stress, is associated with radioresistance in multiple cancer types. Several studies have reported the clinical significance of KEAP1 mutation in brain metastasis; however, the effect of KEAP1 mutations on radioresponse in meningioma has never been reported.

OBSERVATIONS

The authors present the case of a 40-year-old female with a KEAP1 mutation–positive atypical meningioma that was initially treated with resection followed by intensity-modulated radiation therapy (IMRT). Recurrence was observed at 15 months, requiring reoperation and adjuvant stereotactic radiosurgery (SRS). An excellent treatment response was observed at 7 months post-SRS with an improvement in reported symptoms, although bevacizumab was required for the resolution of radiation necrosis observed 2 months post-SRS.

LESSONS

To the authors’ knowledge, this is the first report of KEAP1-mutant meningioma, including its clinical course after comprehensive management. Notably, treatment included multimodal radiotherapy with IMRT followed by SRS. SRS led to an excellent treatment response at the 7-month follow-up. However, radiation necrosis developed after both radiotherapy treatments, suggesting that radiological modification can be beneficial in patients with KEAP1 mutations.

Published: September 2024

The work aims to fabricate Zinc Sulphide (ZnS) and tin-doped ZnS (ZnS: Sn) nanostructures via an easy and affordable chemical co-precipitation process, and then examine the optoelectronic applications for these materials. Xray diffraction (XRD) provided a detailed structural characterization of ZnS and ZnS: Sn nanostructures. Pristine ZnS and ZnS: Sn nanostructures with an average crystallite size in the 2.14–2.71 nm range were seen to develop during this study. A field emission scanning electron microscope was employed to examine the nanostructures' morphology (FESEM). Particle size was investigated using Dynamic Light Scattering and found to range from 26.26 nm to 50.8 nm. Studies using FTIR spectroscopy were used to get the functional groups of the nanostructures. Photoluminescence studies were done to find considerable emission bands. UV-Vis analysis indicated a band gap of 3.45 eV and 3.25 eV for ZnS and Sn-doped ZnS nanostructures respectively.

Published: September 2024

Chalcone derivatives have been proven and documented as non-steroidal anticancer agents. A study of chalcone can be performed as an aromatase inhibitor. One crucial strategy for managing estrogen-positive breast cancer is aromatase inhibition. A total of 13 derivatives of chalcone were synthesized by the aldol condensation reaction and characterized by FTIR, MS, and NMR. Molecular docking was performed by the maestro Schrodinger Suite. In silico ADME study was executed by the QikProp software. All 13 compounds were assessed for the cytotoxicity study in human cancer cell line MCF-7 and are subject to further aromatase inhibition assay on selected chalcone derivatives. Four compounds, 3gA, 3jA, 3kA, and 3lA were found to be more potent chalcone derivatives with their IC50 values of 18.13±1.19 µM, 21.71±1.61 µM, 16.36±1.47 µM and 21.06±1.87 µM, respectively. Using a fluorogenic test kit, the in vitro aromatase inhibitory activity of four drugs (3gA, 3jA, 3kA, and 3lA) was investigated. The values of IC50 for compounds 3gA, 3jA, 3kA, and 3lA were found to be 2.76±0.83 µM, 6.45±3.38 µM, 4.82±1.52 µM and 3.00±1.63 µM, respectively. Lastly, QikProp 4.8 software was used to calculate the ADME parameters (absorption, distribution, metabolism, and excretion) of synthesized compounds. It was concluded that 3gA is the most potent compound having potent aromatase inhibitory activity in comparison to Letrozole with an IC50 value of 2.76±0.83 µM. At the same time, 3jA and 3lA have good aromatase inhibitory activity. Therefore, For the identification of aromatase inhibitory activity, these compounds make good lead compounds for further study as anticancer agents.

Authors: Gryzunov V. V. , Krjukov A. S. , Shestakov A. V. , Zikratov I. A.
Published: September 2024

Relevance. Information systems are integrated with each other, which leads to the need to ensure the protection of the integrated system. The level of trust requires formalizing the concept of trust and studying its nature and structure.

The purpose of the article is to remove the contradiction between the needs to provide access to the resources of the resulting integrated system and ensure compliance with the information security requirements of each of the integrated systems by formulating the concept of trust from the information security perspective.

Methods used: systems analysis, risk management theory, resolutions, iSoft operator equation synthesis method.

Results. Main shortcomings of existing approaches to the formalization of the concept of “trust” are identified. Based on the FIST information system model, a functional trust structure has been developed and formalized in IDEF0 notation for all levels of integrated information systems: supporting level, personnel level, hardware and software levels. Examples of violation of trust and examples of tools for creating trust for each level of the information system are given. The adequacy of the model is illustrated by the example of real integration of information systems. Application of the proposed trust model made it possible to identify features that increase information security risks for the integrated information system from the example.

Novelty. An interpretation of trust as a measure of information security is proposed, in contrast to “risk” as a measure of danger. A tool for quantitative assessment of trust is proposed. A necessary and sufficient condition for creating maximum trust in an information system is formulated and proven by the resolution method

 

Practical significance. The proposed trust model can be used in the development of guidance documents regulating the process of integration of information systems, in setting requirements for service personnel and creating training programs for them, for developing information security tools and methods for their application.

Stress-strain state of building structures taking into account possible local failure of the element
Authors: HAVRYLIUK Oleksandr , NECHYPORENKO Dmytro , ZHUK Veronika
Published: September 2024

The issue of choosing a structural design and material for supporting structures is an important technical and economic task at the stage of developing a design solution. It depends on a number of factors: consequence class of the structure, reliability of the design solution, savings in basic building materials.
The publication provides a classification of design schemes and types of load-bearing structures used in the corresponding solutions. The disadvantages and advantages of using prefabricated and monolithic structures for the installation and subsequent operation of the structural scheme of buildings and structures are considered.
Modern design requirements include ensuring the ability of a damaged structure to adapt to new conditions while continuing to function while ensuring the integrity of human life, property and equipment. New conditions mean the consequences of the occurrence of a certain emergency situation, accompanied by weakening or overloading of the load-bearing structures of a structure or soil foundation: a change in the structural design, a combination of new existing loads and a redistribution of internal forces.
The publication reflects the results of assessing the redistribution of the stress-strain state of the elements of the “base - foundations - load-bearing structures” system as a result of the implementation of a hypothetical emergency situation with the exclusion of the load-bearing structure from operation.
The case of the collapse of one of the vertical load-bearing elements (local failure of the pylon) of an underground floor, which can be used as a dual-use structure, is considered.
Calculations for the stability of the structure against progressive collapse were carried out by numerical modeling in the LIRA SAPR-2019 software using a quasi-static calculation and the method of direct integration of dynamics over time.
It has been demonstrated that the method of numerical modeling the joint work of a building with a soil base affects the results of a calculation of the progressive collapse of the building frame.
The influence of local collapse of a vertical load-bearing element on the redistribution of stresses and strains in the foundation structures of a building section is assessed.
The load on the piles under the pylons around the element removed under the local failure scenario is expected to increase by 15...25%.
A soil base model of adjacent various story structures
Authors: SAMORODOV Oleksandr , TABACHNIKOV Sergii
Published: September 2024

In modern geotechnical engineering, owing to the development of information technology and availability of powerful packages for the calculation of the entire base - foundation - structure system, one of the main research areas is to develop, improve and investigate soil base models to ensure the adequate interaction between the components of the system during the construction and operation of buildings and structures (hereinafter referred to as the “structures”).
The paper proposes an improved soil base model in the form of a continuous layer of finite distribution capability to simulate and calculate adjacent multistory structures in the base - foundations - structures system using powerful calculation packages such as SOFiSTiK, ABAQUS, PLAXIS, SCAD, Lira and others. The improved model considers the parameters of the stress-strain properties of the soils of the bases, the geometric profile taking account of the distribution capability of the base and different boundary conditions, but differs from the existing models in that it has a stepped geometric profile at the lower boundary of the model because of different compressible layer depths under each foundation of the structures. The use of this model improves the accuracy of simulating a soil base for large-sized foundations of adjacent structures to obtain reliable results of the stress-strain state of the base - foundations - structures system.
An example demonstrates how to simulate and calculate raft foundations of a two-section multistory building in the base - foundations - structures system that interacts with an improved soil base model (linear strains of soils under loads are considered here) with reference to different numbers of stories of the sections. The numerical study results show on a specific calculation example that considering different compressible layers depths in the model under differently loaded foundations results in an increase in moment forces of up to 65% as compared with simulating the whole compressible layer, which may lead to the disruption of large-sized raft foundations.
Geotechnical issues of investigation of the technical condition of the structure on weak soils according to the boundary element method
Authors: MORGUN Alla , MET Ivan
Published: September 2024

The article considers the controversial issue of the need to take into account the increasing coefficient to the soil deformation modulus obtained on the basis of compression studies for the design of loess frozen soils. It is well known that weak soils can have low bearing capacity and high compressibility, which makes them difficult to construct and operate structures.
It is known that in laboratory conditions, the modulus of soil deformation is usually determined by compaction with a static load without the possibility of lateral expansion in a rigid ring. The disadvantage of the compression device is the low accuracy of measurements, which is emphasised by many researchers due to the fact that the friction forces of the soil sample on the ring walls reduce, depending on the moisture content and soil type, the vertical pressure applied to the sample during the test. This leads to a false decrease in the actual value of the soil deformation modulus.
To determine the reliability of the two approaches to determining the soil deformation modulus, the settlements of the foundations of grain storage silos on dangerous degraded loess soils were calculated by the numerical method of boundary element (MBE) using an elastic-plastic model, with and without taking into account the soil deformation modulus.
It has been found that solving the problems of assessing the technical condition of a building is associated with geodetic and engineering-geological surveys and the analysis of these results, since the stress-strain state of the building-foundation system and the peculiarities of deformation of the soil base depend on them. After all, the problem of protecting a building from rolling is quite relevant. The design or reconstruction of structures on foundations with weak soils (with a deformation modulus E < 5 MPa) is also associated with the problem of ensuring that the calculated deformation values do not exceed their maximum permissible values for the experimental structure.
The results of numerical studies are compared with the method of finite element (MFE) calculation and experiment.
Interpretation of the data of modern methods of field soil research
Authors: Bondareva Liudmyla , ZIMENKO Ivan , BONDAREV Kostiantyn
Published: September 2024

This study examines modern in-situ testing methods for soils; it investigates the impact of interpreting these methods on the calculated strength and deformation parameters of soils and compares them with tabulated values according to the DSTU (Standard of Ukraine).
In today's world, there is an urgent need for accurate and prompt soil investigations, which are crucial for design and construction. Although laboratory methods are reliable, they often require significant time and resources. The advantage of in-situ methods lies in the fact that testing is performed directly in the soil mass, meaning that the results are not influenced by the transportation and preparation of samples. Conducting tests directly in the soil massif allows for the acquisition of information about soil characteristics and their classification, providing data on soil stratification.
This publication reviews modern methods of in-situ soil investigations, specifically CPTu (Cone Penetration Test) and DMT (Dilatometer Test) [1, 2]. These methods are widely used in Europe, while in Ukraine, they are relatively new and are just beginning to gain popularity. Therefore, it is relevant to compare these methods with the tabulated values provided in Ukrainian reference guides.
The deformation and stress values were compared using three calculation models based on CPTu, DMT, and DSTU data. A comparative analysis of the foundation slab deformations was conducted using models with elastic and elastic-plastic model.
For this purpose, a foundation slab was designed, and a finite element model of the building was developed, examining the foundation on a soil massif with inclined stratification, using both elastic and elastic-plastic soil models.
No Drone’s Sky: Full Spectrum Drone Surveillance and Neutralisation Concept for Enhanced Counter-UAS Framework
Authors: Horváth Gábor
Published: September 2024

Unmanned Aircraft Systems (UAS), commonly known as drones, have witnessed substantial global proliferation in the past decade. Their constructive applications hold the promise of being a useful, yet critical component in creating a more efficient society with the enhancement of safety, efficiency, and facilitating advancements in various domains, ultimately contributing to our modern daily lives. However, the escalating dependence on computer and communication technologies renders, especially small, UAS susceptible to various threats, posing risks to public safety, national security, and individual privacy. Addressing these concerns necessitates the development of innovative technologies designed to detect, track, identify, and eliminate UAS in a manner that upholds safety, security, and privacy. A Counter-Unmanned Aircraft System (C-UAS) is defined as a system or apparatus capable of legally and securely incapacitating, disrupting, or assuming control over an UAS. Recent years have witnessed significant research endeavours aimed at detecting and eliminate drone threats. Detection methodologies encompass acoustic, visual, passive radio frequency, radar, and data fusion techniques, while neutralisation strategies encompass physical capture and jamming approaches. This paper, delving into the realm of small drone surveillance, is the opening segment of a three-part series aims to envision a C-UAS framework; it provides an exhaustive review of existing literature in the domain of UAS surveillance, delineating the challenges associated with countering unauthorised or unsafe drone operations, and evaluating the trajectory of detection to prepare against UAS-induced threats. Therefore, the fundamental objective of this paper is to offer a comprehensive surveillance baseline for a structured vision to a C-UAS framework, thus fostering a research community dedicated to the secure integration of drones into the airspace system.

Published: September 2024

The melting point is an important property that helps generate specific compounds with desired thermos-physical properties. Much work has been done applying quantitative structure-property relationships to improve the melting-point correlations, but they are unreliable. This gap might come from the melting point's sensitivity for small molecular variations and descriptors, which currently do not fully consider all factors determining melting behavior. In this work, we provide a QSPR model for predicting the melting point of a heterogeneous polycyclic aromatic hydrocarbons dataset. The model was generated using a robust hybrid linear approach (Genetic Algorithm-Multiple Linear Regression) and a nonlinear approach named Artificial Neural Network (ANN). Three descriptors were chosen to explain the influence of molecular weight and symmetry on melting point. The resulting QSPR model can model melting-point behavior with an RMSE of 34.88K, a coefficient correlation value of R²=0.887, and a prediction coefficient of Q²LOO= 0.863. This study reveals that the results produced by MLR were appropriate and served to predict melting points. However, compared to the results obtained by the ANN model, we conclude that the latter is more effective and better than the MLR model. Based on the results, our suggested model may be effective in predicting melting points, and the selected descriptors play essential roles in determining melting points.

The problem and the aim of the study. Teachers as key holders of student success must have selfefficacy so that the learning process goes well and gets optimal results. In other words, teachers who have good self-efficacy will be able to foster students' self-efficacy in working on math problems. Researchers propose to analyze the influence of mathematics education students' self-efficiency in solving geometric problems. Participants and Research methods. This research uses a combination of quantitative and qualitative methods, which aims to analyze the self-efficacy of mathematics education students in solving geometry problems. This research was conducted on 43 students STKIP YPUP Makassar, which consisted of 7 boys students and 36 girl students. Two instruments were used in this study, namely the Self-Efficacy Questionnaire (SEQ) and The Geometry Problem Solving Test (GPST). Forty-three students in the research sample. were asked to complete SEQ and GPST-1 with a time duration of 30 minutes and 80 minutes respectively, the implementation of which was directly supervised by the researcher and assisted by lecturers who taught geometry courses. The results were grouped into low, medium and high mathematics ability groups. Then one student from each group was selected to be the research subject. Results. Data analysis for the influence test obtained: (i) F count 56,863 with a significance of 0.001 < 0.05, meaning that students' self-efficacy and Geometry Values simultaneously have a significant influence on the geometry problem solving, and (ii) For SEQ, t count was 3,480. with a significance of 0.001 < 0.05, meaning that the self-efficacy partially has a significant influence on the geometry problem solving, while for GV, the t count is 8.775 with a significance of 0.001 < 0.05, meaning that Geometry Values partially has a significant influence on the geometry problem solving. LS can complete the understanding of aspects of the problem, MS is able to solve problems by understanding the problem and formulating a plan, and HS is able to solve problems on all indicators. Conclusion. Quantitatif: Self-efficacy and geometry values has a significant influence on students' geometry problem-solving. Qualitative: Each subject in each group has a different geometry problem solving process at each stage of problem solving.

Published: September 2024

Introduction. The problem of studying ways and means of educating the younger generation of high moral ideals is an acutely urgent task of modern science, since it is a response to the challenges of the time, laid down in the basis of state policy to preserve and strengthen traditional Russian spiritual and moral values. The purpose of the article is to present the results of a study of the educational impact of a modern children's and youth book on the example of Elena Mamontova's novella "The White Owl" on understanding and strengthening such a traditional Russian spiritual and moral value as mercy. Materials and methods. The tools for socio-pedagogical research were 26 children's books – winners of literary prizes over the past ten years, from 2013 to 2023, and presented on official websites. Among them, the books most in demand by the children's readership were highlighted. The selection was carried out using the methods of analyzing readers' reviews, readers' forms of children's libraries and literary analysis of the ideological and artistic merits of the works. Based on the ideological and substantive criterion, the expert evaluation method selected E. Mamontova's novel "The White Owl" as having a spiritual and moral educational potential. Results. The author summarized the results of the experimental study. The subjects, 22 students of the 7th grade, teenagers of 13-14 years old, first independently, and then together with the teacher discussed traditional Russian values, primarily charity. After the initial independent reading of the book, 82% were able to understand the main idea of the work – the importance of mercy, which indicates the accessibility of the ideological and artistic system of the teenage book to readers. At the same time, special work in the lesson deepened and enriched the students' ideas about mercy: 100% realized the concept of mercy not just as a synonym for kindness, but as the ability to forgive out of compassion, humanity, and show leniency. 60% of the subjects somehow compare themselves with the characters of the story, noting a similar experience in their lives, which indicates a meaningful reading. In addition, some young readers, after special work with the book, were able to go beyond the specific situation and see the problem of mercy in a broad life perspective, talking about the fate of future generations. Conclusion. On an experimental basis, a conclusion is formulated about modern adolescent literature as an important resource for the spiritual development of the younger generation and the strengthening of its national identity. The conclusion is confirmed by the analysis of students' feedback on E. Mamontova's story "The White Owl", which contains moral lessons that allow preserving Russian national identity and help to educate a spiritually developed personality of a teenager.

Introduction. Currently, higher education is considered as one of the drivers of the socio-economic development of the country, in connection with which continuous transformations are taking place in the higher education system, management mechanisms are being formed that can ensure that the results of the activities of universities correspond to their goals, which consist not only in training highly qualified specialists, competitive in the labor market, but also in strengthening university science, including applied scientific research. Achieving these goals directly depends on the readiness of employees, primarily university teachers, to participate and actively contribute to the implementation of adopted development programs. Research aim: a study of the degree of involvement of university employees in the implementation of current trends in the development of higher education, as well as their readiness to contribute to ongoing programs within the framework of their activities. Materials and methods. A survey of university staff was conducted using a questionnaire developed by the author. The sample consisted of 100 people. The research base is the Federal State Budgetary Educational Institution of Higher Education, Moscow State Psychological and Pedagogical University. The questionnaire included 22 questions related to determining the involvement of university employees in the higher education development programs it implements, as well as identifying problems that reduce their willingness to participate in these programs. Results. The survey made it possible to note the need to improve the mechanisms of coordination and involvement of university staff in order to increase the efficiency of activities in achieving development targets determined by the state. Thus, 67% of respondents named the lack of a clear and understandable strategy as the main problem in the development of higher education, and 54% drew attention to the need to improve coordination and communication between levels of higher education management. At the same time, a fairly high degree of staff readiness to take part in the higher education development programs proposed by the university management was noted. Conclusion. Based on the conducted research, it is concluded that special attention should be paid to involving university staff in the development of their development strategies, stimulating their innovative activity and willingness to participate in the implementation of development programs.
