Published: October 2023

The aim of this study was to determine the effects of backfat thickness (mean standardised measurement fromin vivoassessment) of Polish Large White (PLW) gilts on their reproductive performance and productive lifespan. The study included 5,122 PLW gilts from 160 breeding herds in Poland, which reproductive performance was analysed on the basis of the rearing results of 20,662 litters. The gilts were divided into two groups differing in mean standardised backfat thickness (P2+P4/2) on the performance test day: I≤10 mm, II>10 mm. Sows in group I vs II had a three month shorter herd life (P≤0.001), gave birth to fewer litters and piglets (P≤0.001), but the average number of piglets born alive and reared to 21 days of age/litter was higher in them (P≤0.001). The number of live-born piglets per 100 days of reproductive life in group I was greater than in group II (P≤0.001). When culling sows in cycles 1–8 and later, there was more intensive culling in group I vs II from cycle 1 to 6 and a lower percentage of sows remaining in the herd. In group I vs II, the proportion of sows with a lifetime productivity of fewer than 30 piglets was 5.5 percentage points higher and that with a production of more than 100 piglets was 1.9 percentage points lower. Our results indicate that the level of fat reserves determined in vivo in breeding gilts can be a preliminary information about the reproductive potential of sows and their predisposition to longevity.
Resilience and Vulnerabilities Related to Russia’s Invasion of Ukraine: The Emergence of a New Club of Nato and EU Members
Authors: Ivanov Ivan Dinev
Published: October 2023

Тhis article compares and contrasts macro- and micro-foundational explanations about disinformation and resilience in Europe as a result of Russia’s war in Ukraine. It presents micro-level data about the shifting public opinion in Europe after Russia’s invasion in Ukraine on Feb 24, 2022 on the topics of NATO and EU support and favorability, sympathy for Ukraine and condemnation of Russia, including support for sanctions against Moscow (Pew Research Center 2021, 2022). The study compares and contrasts traditional macro-level analytical frameworks such as deterrence, institutionalization and adaptation. I argue that a combination of macro- (or institutional) and micro-level factors (associated with the idiosyncrasies of the domestic public opinion) best explain the shifting attitudes since the beginning of the War in Ukraine. Against the backdrop of NATO and the EU’s increased resilience, a new group or sub-club of “vulnerable” allies has emerged among some central and east European nations. The article evaluates different constraints and vulnerabilities and makes recommendations how to reduce misinformation and contestation in these states.
The Analysis of Masculinity in Advertising: A Qualitative Study Based on Consumer Perceptions
Authors: Kreicbergs Toms
Published: October 2023

The aim of the research was to explore Generations Z’s perceptions of masculinity in advertising and determine which type of masculinity and which masculinity characteristics consumers favor in a masculine character or the advertising message centered around masculinity. The author conducted three focus groups with a demographic: Latvian Generation Z. Qualitative content analysis of the focus group interview transcripts was conducted using Nvivo 11 qualitative data analysis software. The research concluded that Latvia’s Generation Z preferred modern masculinity depictions in advertising over traditional ones, and advertisers should not depict masculinity with stereotypes but rather emphasize diversity, self-acceptance, and emotionality and depict masculinity as an important topic.
Internal Direct Products and the Universal Property of Direct Product Groups
Authors: Nelson Alexander M.
Published: October 2023

This is a “quality of life” article concerning product groups, using the Mizar system [2], [4]. Like a Sonata, this article consists of three movements.

The first act, the slowest of the three, builds the infrastructure necessary for the rest of the article. We prove group homomorphisms map arbitrary finite products to arbitrary finite products, introduce a notion of “group yielding” families, as well as families of homomorphisms. We close the first act with defining the inclusion morphism of a subgroup into its parent group, and the projection morphism of a product group onto one of its factors.

The second act introduces the universal property of products and its consequences as found in, e.g., Kurosh [7]. Specifically, for the product of an arbitrary family of groups, we prove the center of a product group is the product of centers. More exciting, we prove for a product of a finite family groups, the commutator subgroup of the product is the product of commutator subgroups, but this is because in general: the direct sum of commutator subgroups is the subgroup of the commutator subgroup of the product group, and the commutator subgroup of the product is a subgroup of the product of derived subgroups. We conclude this act by proving a few theorems concerning the image and kernel of morphisms between product groups, as found in Hungerford [5], as well as quotients of product groups.

The third act introduces the notion of an internal direct product. Isaacs [6] points out (paraphrasing with Mizar terminology) that the internal direct product is a predicate but the external direct product is a [Mizar] functor. To our delight, we find the bulk of the “recognition theorem” (as stated by Dummit and Foote [3], Aschbacher [1], and Robinson [11]) are already formalized in the heroic work of Nakasho, Okazaki, Yamazaki, and Shimada [9], [8]. We generalize the notion of an internal product to a set of subgroups, proving it is equivalent to the internal product of a family of subgroups [10].
How to do languaging(s), language games and languages
Authors: Ilyin Mikhail
Published: October 2023

The article elaborates on substance-form aspects of integral communicative practices. Respective substance matters emerge with their shaping into formative and formal modes within the integral bio-social existence and experience of humans. Instrumentally modes help humans to shape or form their irregular substance matters into in-formed mental, behavioral and communicative practices.

The article outlines interpretations of respective transformations and processes from Aristotle, Descartes and Kant to Russell, Wittgenstein, Austin and theoreticians of ongoing cognitive and languaging revolutions. The rigid opposing of the ultimate substance/form abstractions provokes conceptual impediments that result in the notorious pseudo-Cartesian mind-body problem. It is possible to overcome it by refocusing on actual middle ground integral developments including actual psychosomatic and mental processes, human communicative interactions and their pragmatic activities. A promising way to do that is to develop intellectual instruments similar to accommodating Hjelmslevean distinction of content and expression planes or relatively integral substance-form complexes.

The article suggests a range of instrumentalities to methodologically reinterpret actual middle ground practices of languaging and language games. To that effect, it suggests a few complementary ways of their embedding and enacting, particularly new modes and procedures to conceptualize prerequisites and outcomes, externalities and affordances of the matching middle ground practices.
In Search of a Head Start: Marketing Opportunities in the Metaverse
Authors: Dwivedi Yogesh K. , Hughes Laurie
Published: October 2023

The concept of the metaverse, a virtual world with immersive 3-D environments, has gained significant attention and is expected to affect how we interact and communicate. While there is no consensus on its future, many brands are preparing for its potential. The metaverse offers unique marketing opportunities, enabling brands to provide offerings that are impossible in the real world. It can serve as a third space for retailing, where brands can create immersive experiences and overcome physical limitations. Metaverse advertising should be interactive and immersive to maximize its potential, while brand communities and events in the metaverse offer new avenues for engagement. The metaverse also allows companies to unlock new revenue streams through virtual products, NFT collections and digital twins. However, the metaverse brings challenges, including technical issues, privacy concerns, avatar misbehavior and the need for virtual and real coexistence. Brands must navigate these challenges and conduct further research to understand and maximize the benefits while minimizing risks in the metaverse.
Eye Contact Matters for Consumer Trust – Even with Robots
Authors: Kaiser Carolin , Schallner René , Manewitsch Vladimir
Published: October 2023

The integration of AI into consumer services is transforming the way people make decisions. AI is becoming more human-like, with chatbots, voice assistants and robots adopting human features and behavior. Consumers react differently to assistants with a human-like appearance than to advice from a web page, and the behavior of AI advisors influences consumer trust and decision-making. The results of an experiment comparing human advisors, robotic advisors with and without eye contact, and text-based services show that human advisors are trusted the most, but robotic advisors are preferred over text-based services. Human-like advisors increase trust and satisfaction. Extended human features like eye contact are essential for establishing trust and positive consumer responses. Companies should consider using humanoid advisors and incorporating eye contact to enhance customer experience. Consumers should be aware of the influence of human-like AI and stay informed about AI developments.

Immersive technologies such as augmented reality (AR) ) and virtual reality (VR) enable memorable experiences along the entire customer journey as the combination of real and virtual elements creates innovative forms of consumer-brand interaction. Read in our interview how to implement successful immersive campaigns that people care about and share on social media. Julian Weiss, co-founder and CEO of Hamburg-based agency headraft, expects many more XR (extended reality) applications as “retailing will increasingly become an experience space.” He sees their greatest potential in a symbiosis of real and virtual elements.
Chancen für mehr Wachstum durch eine mutige Steuer- und Finanzpolitik
Authors: Hüther Michael
Published: October 2023

Germany’s manufacturing sector still shows gross fixed capital formation below pre-coronavirus levels and has been stuck in a recessionary trend since 2018. The advantages of German industry are at risk. Therefore, the federal government has to i) ensure that time is bridged and companies are supported until cheap energy is available, ii) improve investment conditions, iii) eliminate locational disadvantages (tax burdens, energy costs) and strengthen advantages (R&D, human capital) and iv) reduce bureaucratic costs. There is need for tax and growth policy reform. In this regard, the debt brake turns also acts as an effective brake on tax cuts and is thus questionable in terms of growth policy.
Die Investitionswende braucht eine mutigere Wirtschaftspolitik
Authors: Bauermann Tom , Dullien Sebastian , Rietzler Katja
Published: October 2023

Aggregate investment in Germany has developed much less dynamically than forecast prior to Russia’s invasion in Ukraine. The reasons for the subdued investment dynamic are uncertainty about future energy prices, increased interest rates and – in the case of housing investment – increased construction costs. The recently propsed Wachstumschancengesetz is insufficient to fundamentally alter these obstacles. Bolder policy measures are needed.
Die Verlängerung einer modifizierten Strompreisbremse zur Stärkung der deutschen Wirtschaft
Authors: Krebs Tom
Published: October 2023

This article summarises the results of a study on the Germany energy crisis and the need for an extension and modifications of the electricity price break. The study shows that the energy crisis led to a short-run output loss comparable to the output losses associated with the COVID-19 crisis in 2020 and the financial crisis in 2008/2009. In addition, real wage losses during the energy crisis are the largest losses on record. Finally, there is the risk of permanent economic damage leading to a period of economic stagnation. The extension and modification of the electricity price break until 2030 is an important policy instrument to help the Germany economy avoid economic stagnation. The argument in favour of such price controls is that the energy crisis has pushed the electricity price above its long-run equilibrium value.economic stagnation. The economiy argument in favor of such price controls is that the energy crisis has pushed the electricity price above its long-run equilibrium value.
Konjunkturbereinigung in der Schuldenbremse bei überraschend hoher Inflation
Authors: Kremer Jana , Kuckuck Jan , Wendorff Karsten
Published: October 2023

The recent high level of inflation temporarily eased government budgets. As a result, conventional estimation methods for cyclical adjustment are likely to temporarily paint an overly favourable picture of the underlying budgetary situation. This also applies to the cyclical adjustment in the German Federal Government’s debt brake, as we argue below. We compare this with our proposal for cyclical adjustment reform: it is likely to be too optimistic in the face of surprisingly high inflation. However, it is very unusual that inflation is underestimated so much. Overall, we continue to consider our proposed reform to be advantageous compared with the current approach.
Was können frühere Arbeitszeitverkürzungen für die Debatte um die 32-Stunden-Woche lehren?
Authors: Seifert Hartmut
Published: October 2023

This article asks what lessons can be learned from the introduction of the 35-hour week for the current debate in the steel industry. In retrospect, it can be shown that a compromise in collective bargaining policy cleared the way from the 40- to the 35-hour week. A package of shorter and more flexible working hours could also make the 32-hour week possible in the steel industry in a similarly cost- and distribution-neutral way, especially as large sections of the workforce there already work less than 35 hours.

Published: October 2023

The Objective was to improve medical and diagnostic care for patients with obstructive jaundice of tumor genesis.

Methods and Materials. Retrospective analysis of the treatment results of 309 patients with obstructive jaundice of tumor genesis. We studied the results of endoscopic transpapillary and/or percutaneous transhepatic antegrade endobilliary minimally invasive surgical interventions of 307 (99.3 %) patients. We carried out the analysis of complications, reasons and possible elimination path. A new, more effective method of trepan-biopsy of tumors of the pancreatic head and distal choledochus and devise for it implementation were developed (patent № 2722655, 2747591).

Results. Minimally invasive decompression interventions at the first stage of treatment of patients with obstructive jaundice of tumor genesis reduced the percentage of fatal postoperative complications to 1.3 %. The first results of the application of the developed trepan-biopsy method showed their high efficiency, reliability and safety.

Conclusion. The differentiated approach to the choice of the method of decompression of the biliary tract at the first stage is important for improving the results of treatment. The use of the method of simultaneous puncture transhepatic billioduadenal drainage with trepan-biopsy of tumors of the pancreatic head and distal choledochus is, as it seems to us, a new, promising adjustment in solving the problem of morphological verification of tumors of the hepatopancreatoduodenal zone and reducing the time of diagnosis and treatment of patients with obstructive jaundice of the tumor genesis.

Authors: Yuldashev R. Z. , Aliev M. M. , Shokhaidarov Sh. I.
Published: October 2023

The objective of the work was to study the efficacy of minimally invasive endoscopic treatment of esophageal varices (EV) in children with extrahepatic portal hypertension (EHPH).

Methods and Materials. Eighty children aged 3 to 17 years of age with EHPH included in this study. The patients were divided into three analysis groups. The group I (n=14) included children with EHPH who had not previously undergone any surgical interventions and endoscopic ligation of EV was performed against the background of acute bleeding or after medical hemostatic treatment. The group II (n=37) included patients who had undergone the endoscopic treatment of EV after an unsatisfactory outcome of previously performed surgical interventions. The group III included 29 children who underwent only azygos-portal disconnection procedures. We performed the comparative analysis of the severity of EV before and after sessions of the endoscopic treatment of EV, as well as the analysis of the frequency of recurrent bleedings in comparison groups.

Results. According to the research results, recurrent gastroesophageal hemorrhages were noted in 44.4 % of cases in the group I. In the group II, 37 patients underwent a total of 68 sessions of the stage endoscopic treatment of EV. According to the control endoscopic examinations, there was a significant reduction in the risk of bleeding from EV between ligation sessions (p=0.001) of the endoscopic treatment of EV. During the follow-up period, in the group II, recurrent bleedings from EV were noted in 6 (16.2 %) patients. Whereas in 10 (34.5 %) children of the group III, recurrent gastroesophageal hemorrhages were noted in the postoperative period. The analysis showed a significant correlation of the presence of «red flags» with recurrent episodes of bleedings in children of the group II after the endoscopic treatment of EV (r=0.32 p=0.05). Analysis of the causes of recurrent gastroesophageal bleedings in children of the group III did not reveal significant differences in such parameters as the degree of EV and «red flags».

Conclusion. Thus, the endoscopic treatment of EV is a safe and effective method of secondary prevention of bleedings from EV. The question concerning the primary prevention of gastroesophageal hemorrhages require further study.

La recepción mexicana de Hipólito de Eurípides en Fedra y otras griegas de Ximena Escalante
Authors: Gutiérrez Francisco
Published: October 2023

La obra de la dramaturga mexicana Ximena Escalante Fedra y otras griegas (2002) se enmarca en el diálogo fructífero que ha existido entre la dramaturgia latinoamericana y la tragedia ática, el cual ha adquirido un nuevo impulso gracias a las perspectivas de las dramaturgas del siglo XXI. En este artículo, abordaremos a la autora mexicana y su recepción de la tragedia Hipólito de Eurípides. Para analizar dicha recepción se hará énfasis en dos aspectos presentes en ambas obras. Por una parte, la construcción de la figura de Fedra a partir de su adecuación a lo que se espera de su rol como mujer y, por otra, cómo el argumento en la obra de Escalante invita a reflexionar la influencia de los roles de género en las relaciones sexoafectivas.
The Mexican reception of Hippolytus by Euripides in Fedra y otras griegas by Ximena Escalante
Abstract
The play Fedra y otras griegas (2002) by Mexican playwright Ximena Escalante exemplifies the fruitful dialogue that has existed between Latin American theatre and Greek tragedy. This relationship has acquired a new impulse due to the perspective of the female playwrights of the XXI century. The article addresses the Mexican author and her reception of the tragedy Hippolytus by Euripides. Emphasis is placed on two aspects of both works: the construction of Phaedra’s character based on what is expected of her role as a woman, and how Escalante’s play invites us to reflect on the influence of gender roles in sexual-affective relationships.

Correlation and variability analysis for yield and related traits of sweet corn in backcross populations
Authors: Abikkumar C. , Senthil N. , Mohanapriya B. , Parathasarathi G. , Sivakumar S. , Gurusamy K. , Sudha M.
Published: October 2023

The 14 biometrical traits of sweet corn were studied in BC2F2 and BC2F3 generations of SCM-Se-Y-1 x UMI 1230β+ to analyse the mean performance and frequency distribution patterns to select potential individuals with high yielding agronomic traits. The mean, GCV, PCV, heritability, and GAM were calculated for all the recorded traits. The Pearson correlation coefficient revealed the strong and positive association of cob weight with cob length, number of kernels in a row and number of kernel rows per cob. Similarly, single plant yield shows positive correlation with number of kernels per row, number of kernel rows per cob, cob length and cob weight. The populations exhibit high PCV than the GCV, which reflects the direct influence of environments on trait performance. The BC2F2 generation exhibits greater trait variability, while BC2F3 shows signs of stabilization. Both generations display high heritability, indicating strong genetic influences for yield related traits. Heritability and GAM for the trait cob weight and single plant yield were higher, which gives added advantage for isolating the superior individual. The results of this study suggest that the selection of agronomical traits to enhance yield in sweet corn is of utmost importance due to its far-reaching economic, nutritional, and environmental implications.

Considering the current context of the coronavirus 2019 (COVID-19) pandemic, people should equally comply with both vaccines and non-therapeutic health protective behaviors. This study investigated public adherence to vaccination, behavioral changes against COVID-19, and their determinants in Bangladesh during the pandemic. The study was conducted during March and April 2022 among 940 Bangladeshi adults selected by multi-stage sampling, and data were collected through face-to-face interviews using questionnaires. Significant determinants and their relationships were described through hierarchical regression and structural equation modeling (SEM) based on the theory of planned behavior (TPB). Nearly half of the subjects (48.2%) showed poor vaccine adherence and COVID-19 prevention practices. During the pandemic crisis, the majority of the respondents (86.7%) used face masks, but only 12.7% of the respondents used them regularly. Less than half (44.9%) received COVID-19 vaccines regularly. Along with some sociodemographic factors, knowledge (p < .001), attitude (p < .01), and intention (p < .001) regarding COVID-19 prevention were significant in predicting vaccine adherence and healthy practices in a hierarchical regression. Self-control was highly significant in SEM, showing the highest effect (p < .001). Policies based on the TPB model could be adopted to improve preventive behaviors against COVID-19.
The problem of freedom in the philosophy of John Locke: semiotic interpretation
Authors: Ukhov Artem Evgen'evich , Kovrov Eduard Leonidovich , Simonyan Eleonora Gamletovna
Published: October 2023

The article shows the connection between the social constructions of political liberalism and its ontological justification in the system of J. Locke. With the help of semiotics and comparative philosophical analysis of the views of modern philosophers B. Spinoza, T. Hobbes, J. Locke, R. Filmer, J.-J. Rousseau, I. Kant, such problems as the nature of state power, the concept of freedom, natural law, social contract, the right of the people to revolution are analyzed. The semiotic context of natural law is revealed, and it is concluded that happiness, as the goal of New Age individual’s quest, according to Locke, is thought to be a rational and, therefore, a free being. Linking the natural need to be a free being not only with the organization of state power, but also with religious need, Locke concludes that political participation itself can be considered not just as a way to achieve freedom, but also as the purpose for a person to improve themselves morally and politically. For Locke, state power turns out to be an integral part of society, and the balance between them always shifts towards society as the source of the social contract. At the same time, the negative meaning of freedom in Locke prevails over the positive, saving the latter from sliding into totalitarianism of the Jacobin type, as in Rousseau. The conclusion is drawn about the relevance of ideas about the need for free choice of citizens to build a rule of lawful state and develop democracy.
Toward an Efficient Method for F-16 Limit Cycle Oscillation Prediction
Authors: Kariv Daniel , Kunz Donald L. , Iovnovich Michael
Published: October 2023

This study presents the development and validation of a computationally efficient prediction framework for the well-known nonlinear F-16 limit cycle oscillation (LCO) phenomenon. The framework relies on a simple physical working model that has been suggested and demonstrated in the past according to which LCO is primarily a flutter instability that is bounded by the existence of nonlinear structural damping (NSD), although potentially affected by nonlinear aerodynamic effects as well. In the framework developed herein, the NSD model is derived and calibrated using a novel method that simplifies the process and allows applicability of the derived NSD models for multiple aircraft download cases. Good LCO prediction capabilities are obtained using the suggested method in terms of LCO levels and trends with flight conditions, as demonstrated using four F-16 test configurations. This framework also allows several practical benefits, which makes it particularly suitable for industrial-level applications.

An analysis of studies and publications on the issues of determining the stress-strain state of constituent structures has shown that the problems of choosing and modeling the operation of structures in the form of infinitely long cylindrical shells with a soft, weightless elastic layer have not received enough attention in the scientific literature today. The use of modern approaches to the construction of mathematical models and algorithms makes it possible to take into account various kinds of dynamic loads that are transferred to structural elements in the form of cylindrical shells.The aim of the article is to develop an analytical method for calculating cylindrical shells with a weightless soft elastic layer under the action of a moving radial load.Based on the principles and approaches to the analysis of non-stationary dynamic processes in complex shells, the paper presents an algorithm based on the application of the integral Fourier transform along the axial coordinate, as well as the use of the Runge-Kutta numerical method for integrating the transformed differential equations of shell motion in the image space. Cases of load movement with different speeds and uniform pressure wave movement are considered. The dependence of the radial displacements of the shell on the reaction of the elastic layer, represented by an approximate model, taking into account only the radial displacement, is determined. The cases of motion of a radial axisymmetric load both with constant and with varying speed are investigated. The distribution of shell deflections along the length is given for different moments of time during the movement of the load at a constant speed, as well as for the slow movement of the ring load.In this work, for the first time, a mathematical model of the non-stationary behavior of a shell with an outer layer under the action of a moving load is constructed. A comparative analysis of various shell models has been carried out and deformation patterns of both accelerated and slow motion have been constructed. The transient processes that occur at the moment of load application and the subsequent time intervals immediately after this moment are considered. The presented materials can be used for dynamic modeling of the operation of structures in the form of plates and shells.

Recently, low-power CNC machines for processing wood, plastic and soft metals have become very popular. They found their application not only in large productions, but also in home use in small workshops. The total processing time is signifi-cantly increased due to the time spent on fixing the workpiece to the table. In addition, this type of machine is used for cutting and processing sheet materials, during fixing of which deformation occurs due to their insufficient rigidity and, as a result, low processing accuracy and increased processing allowances. Therefore, there is a need to increase the clamping area of such workpieces, and since the use of clamps is possible only along the perimeter of the workpiece, there is a need to search for new, effective methods of fixing. The basic equipment of woodworking machines with CNC includes only standard clamping devices. Equipping with more modern and efficient clamping systems is made to order and requires additional resources, as the machines have different working fields and cutting power. The article shows the results of the design of a vacuum table for a CNC milling machine, which was developed at the Department of Mechanical Engineering and Woodworking Technologies of Chernihiv Polytechnic National University. The necessary equipment has been selected; efforts and fixing time have been calculated; a CAE analysis of the deformations of the workpiece with different fixing methods was performed.

Plastics are one of the most common materials. Due to its high technical and economical characteristics, this class of materials is used in almost all industries, that is why further growth of the production of plastic products is predicted. Today, the biggest problem in the field of polymer processing by extrusion is to ensure the best possible parameters of resource-energy efficiency of equipment. At the same time, the creating of compounds based on polymers is developing very actively, which requires more flexibility from extrusion lines, since a large number of compositions which differ in their characteristics can be developed on the base of a polymer. The factors listed above have led to cascade extrusion lines become increasingly wide-spread in industry today. Analysis of the extrusion equipment market showed that the schemes with a high-speed double-string extruder at the first stage is more popular. However, the desired mixing quality can be achieved by using a much simpler disc extruder. The article is a review that aims to determine the possibility and feasibility of more efficient arrangement of a cascade scheme for processing composite materials using a disk extruder. Theoretical and experimental studies have shown that melting processes are more efficient in the field of high shear rates at low pressures. Disk extruder is great option for that objective. In this scheme, it is proposed to use a dose feed disk extruder as a homogenizer, and a gear pump as a metering device which allows to reduce pressure and capacity fluctuations before forming device to less than 1%. As a result, it has been determined that the proposed design of the extrusion plant will be more energy efficient than the options on the market and will be able to significantly reduce pressure and performance fluctuations at the inlet to the forming device.

Currently, the processing of a large amount of data, which have a different physical or biological nature, remains an important task, since all parameters have their own distribution laws, which in general differ from the Gaussian one. Such a set of data does not make it possible to apply standard methods of statistical processing. There is no general classificationmethod either.The analysis of research and publications made it possible to formulate the tasks of the research presented in the work, how to choose a relevant statistical approach that would optimally take into account the peculiarities of endocrinological research, which include anthropological, biochemical and other indicators. The paper proposes an approach based on image classification using distance functions.The purpose of the article is to compare methods of treating obesity and hypertension using statistical data processing methods, namely by calculating the Mahalanobis distance between groups of patients and to prove the effectiveness of the new proposed method of treatment.The article proposes a new approach to the statistical processing of a large amount of diverse data, based on the use of the Mahalanobis distance. The ways of decision-making based on the Mahalanobis distance measurement between a sample of relatively healthy patients and two samples of patients were considered: the main - a group of patients receiving a new treatment, and an experimental - a group of patients receiving standard treatment for excess weight and arterial hypertension.Therefore, the paper proposes for the first time the use of the Mahalanobis distance as a criterion for evaluating a large number of diverse physical indicators taken from a biological object.

Calculation of elastic structures for strength and stiffness is important for their safe operation. The need for calculations is caused by structural deformations under the influence of external forces or temperature.The objects of our research are the equation of the axis of an elastic beam during its flat bending, as well as the equation of the angle of rotation of the beam section. These equations are differential. A certain complexity of their solution led to the simplification of equations in classical sources of information. Approximate solutions of these equations are considered there.But when using approximate calculation methods, you need to be able to assess their accuracy, that is, the degree of approximation to the exact result.The goal of our research was to obtain exact solutions. The exact solution of the beam equations is important to avoid its critical deformations.The article presents the exact analytical solutions we obtained for the exact equations of the bent axis of the beam and the angle of rotation of the beam section. The advantage of the exact solution was revealed, in particular, in the fact that the largest value of the deflection and angle of rotation of the beam section can be obtained directly from the properties of thefunctions that describe the solution.Another advantage of the exact solution was the possibility of obtaining an approximate solution with a predetermined accuracy. In the mentioned classical sources of information, the assessment of accuracy was derived from the range of the maximum deflection of the axis during practical calculations of structures.We have obtained a method of analytical assessment of the accuracy of the obtained solutions. The ability to assess the accuracy of calculation results is an important aspect of their practical application. This is important, in particular, for check-ing and clarifying the safe range of movements of beam points during its operation.An example of calculating the deflection and angle of rotation of the beam cross-section with a given load on the axis of the beam is shown
