Usually, for the numerical solution of elastoplastic boundary value problems based on deformation theory of plasticity is used an elastic solutions method proposed by A.A. Ilyushin. In literatures the method of elastic solutions relative to boundary value problems of the theory of plastic flow is called the method of initial stresses or the method of initial deformations. In this paper, to solve the boundary value problems of the deformation theory of plasticity of transversally isotropic bodies, it is used relatively “simple” finite-difference method considered in combination with the iterative method, that is, the elastic solution method. The essence of the method is to construct symmetric finite-difference equations, separately for internal and boundary nodes of the area under consideration, and to solve them with respect to “central” or boundary node displacements and the organization of the iterative process. Elastoplastic problems are solved numerically for isotropic and transversely isotropic parallelepipeds under various boundary and boundary conditions. The obtained results are consistent with the known solutions, which shows the validity of the applied methodology. It is explored the spreading of the zone of plasticity and the effect of anisotropy on their distribution.

An physicomechanical properties experimental study of the modern antifriction materials number was performed as part of the work. The 6 polymers and composites based on them having the greatest prospects for use as antifrictional coatings and interlayers in contact nodes are selected. The materials showed a nonlinear deformation behavior model in experimental study of samples. Therefore, the deformation theory of elastic-plasticity for the active loading case is chosen to describe the material behavior model in the framework of the first approximation. A numerical model of deformation of cylindrical samples under constrained compressionan experiment has been constructed. The optimal finite element mesh with a gradient decrease in the element size to the contact area of the cylindrical samples with the press plates has been selected. As part of the numerical experiments series, it was established: samples deformations from modern antifriction composite materials by 25–30 % more than other polymers considered, with one level of contact parameters; the modulus of the maximum contact tangential stress of all the materials examined is on average 25 times lower than the contact pressure.

This article describes a method for applying an encoded digital steganographic watermark to a digital image and its subsequent extraction using Haar wavelets. The method of applying a digital steganographic watermark by key, and highlighting this sign with a key, is considered. The relevance of this method of applying and highlighting a digital steganographic watermark is considered. A few words describe the method of splitting a signal into sub-signals using the Haar algorithm and how it is applicable in the context of digital images. The results of checking the application of a digital watermark for resistance to various transformations are presented, such as: blurring with a 3×3, 5×5 core, jpeg compression with a compression ratio of 50 and 70 %, deleting the 1 LSB, 2 and 4 LSBs. Corresponding images are presented that illustrate the results of tests for resistance to conversion of a digital steganographic watermark. A small, illustrative and easy to implement example of applying a digital steganographic watermark, as well as its extraction using a previously created key using simple coding, which consists in the fact that the columns of pixels of the original image are shifted by a certain number of positions, is presented. Also, the article provides a brief description of the LSB algorithm and considers the main advantages and disadvantages of the algorithm developed and presented in this article with the standard LSB algorithm. In conclusion, the corresponding conclusions were drawn about the applicability of the developed algorithm, about its shortcomings and advantages, described in this article.

New theorem on the controllability of linear functional-differential system of evolutionary type and algorithm for practical verification of controllability are obtained, which can be applied even in the case when the coefficients of system are not continuously differentiable over the time interval under consideration. Special cases of this system are nonstationary systems with distributed and concentrated delay, integro-differential systems with a Voltaire integral and ordinary differential systems. The main results obtained are formulated in the form of 12 theorems and 3 corollaries. On their basis an algorithm for practical verification of the controllability of the system under consideration using a computer is built. Examples illustrating the operability of the obtained theorems and the algorithm are given. The algorithm is implemented in the Maple 17 package for examples of second-order differential systems with delay.

Distributed fiber-optic sensors are becoming an increasingly common solution for monitoring and diagnosing extended information transmission lines, industrial devices, buildings and devices. One of the directions – Brillouin reflectometry, which allows diagnosing a fiber line for changes in ambient temperature or mechanical deformation, is becoming increasingly popular for engineers and researchers. However, modern standards impose increasingly strict requirements on diagnostic systems in terms of the accuracy of determined parameters. For Brillouin reflectometry, where the value of the environmental parameters is determined by the position of the maximum of the Brillouin gain spectrum, the task of more accurately determining this maximum becomes the main one. The paper considers modern computer-computational methods for detecting the maximum of the Brillouin gain spectrum in an optical fiber. The authors note that imperfections in the shape of the optical spectrum, such as the signal-to-noise ratio, as well as possible digital defects that occur during digitization, can significantly impair the accuracy of the system. The authors consider three approaches to detecting the maximum of the spectrum: the classical method of Lorentz curve fitting, the method of cross-correlation with the ideal Lorentzian function, as well as the method of inverse correlation developed by the authors earlier. To combine the results of the work of the three methods, a neural network model was developed that accepts the input data of each method, together with the parameters of noise and distortion of the spectrum. The model is presented in the form of a four-layer perceptron with two hidden layers. As a result, the authors achieved an increase in the accuracy of determining the position of the maximum of the spectrum by 10% on the model data.

Published: January 2022

This article is devoted to the study of changes in the main indicators of the level of the unemployed population. The dynamics of the officially registered number of unemployed aged 15–72 years is analyzed. The relevance of this work was that the problem of unemployment is a very important problem in our society. Without solving the problem of unemployment, it is impossible to find solutions to improve not only the economic, but also the moral, moral and spiritual situation in Russia. The purpose of this work was to build a forecast model for the development of the number of unemployed in the Perm Region. It is shown that there was a good correlation between the wages of employees, the number of the population, the growth of high-performance jobs, the cost of a fixed set of consumer goods and services, the age composition of the population older than the able-bodied, the migration growth of the population and the growth rate of the number of unemployed in the Perm Region. The analysis made it possible to construct a linear multivariate model and a model in the state space. It is shown that these models cannot be used to predict the number of unemployed, due to poor predictive properties (the sum of the squares of deviations for a linear multivariate model in this case is 0.295, for a model in the state space – 2.354). At the same time, a regression-differential model of the change in the number of unemployed aged 15–72 years in the Perm Region was built. The obtained data showed that for this model, the sum of the squared deviations is 0.091. This suggests that the regression-differential model best describes the number of unemployed people aged 15–72 years in the Perm Region. Based on the obtained model, a forecast of the distribution of the number of unemployed in the region under consideration for 2021 and 2022 was made. The results obtained indicate that there will be a positive trend in reducing the number of unemployed. Over 7 years, it will decrease by 21.8 %.

Neste artigo se expõe o resultado do estudo monográfico sobre a emergência das narrativas contra-hegemônicas no ciberespaço. Por narrativas contra-hegemônicas compreende-se aquelas que são produzidas por grupos que não se sentem representados na mídia ou que criam um discurso que vai de encontro com o que está presente na mídia hegemônica, como é o caso da narrativa da assexualidade. A hipótese que nos moveu é que essa emergência tem lugar em decorrência da processualidade da midiatização e, nela, o ciberespaço. Tratou-se de um estudo de caso, no qual o objeto de estudo teve por recorte dez excertos que nos permitem identificar a evolução da narrativa da assexualidade na mídia, no presente artigo haverá a exposição de dois deles.

Published: January 2022

Sem subtítulos e no estilo de uma conversa, em que assumimos conscientemente o propósito do ensaio de não se querer chegar nem de longe a conclusões finais sobre um assunto qualquer, o texto se ocupa com temas, questões e miradas teóricas e epistemológicas de interesse dos integrantes do grupo de pesquisa “Da Compreensão como Método”, instalado junto ao Programa de Pós-Graduação em Comunicação Social da Universidade Metodista de São Paulo. Alguns dos princípios epistemológicos em pauta, como os da incerteza e da complementaridade dos opostos, comparecem no texto, ao lado das demais temáticas, como um convite para uma troca compreensiva de ideias, mais do que como afirmação de uma ou de várias verdades. Um pensamento em movimento, a compreensão levanta a pergunta sobre os impactos de todo conhecimento na vida social e política: a epistemologia do conhecimento não abdica da sua condição de epistemologia pragmática.

Wayfinding in spatially complex public transit environments poses unique navigational challenges. Transfers, delays, barriers, and user capacity all influence the usability of a system. Because of the smartphone, how we navigate through these systems, and interact with the surrounding environment, is changing. The smartphone provides a spatio-temporal strategy that removes the reliance on our immediate environment and personalizes the wayfinding process -- unlike that of transit schedules, signs, and maps. How does smartphone usage influence performance and the wayfinding experience? This paper looks at smartphone usage of twelve participants through a shadowed commented walk, known as a Destination-Task Investigation, in Munich’s public transit system.  The study provides insights into the role and the influence of smartphones during the wayfinding process. Furthermore, it shows that Apps providing integrated spatio-temporal information, such as Google, were used most frequently, especially for confirmation during navigation.
Book Review / Art and Design in 1960s New York
Authors: Katz Kyle
Published: January 2022

In Art and Design in 1960s New York, Amanda Gluibizzi, explores the intersectionality of art, design, advertising, and signage during the period of great social unrest. The 1960s were a challenging time for New York. High poverty, widespread crime, and economic decline culminated in New York City defaulting on its credit in 1975. This social turmoil coincided with the flourishing of art and design in New York, as both fields responded to an urban environment in flux. It is within this context, a city in crisis, that Gluibizzi examines the ways in which artists began to incorporate elements of the city, its design, its civic and commercial signage, into their art. Fundamental to this analysis is how the fields of art and design responded to each other during that time, and how the lines between the two fields became increasingly blurred as artists and designers pushed the boundaries of their respective fields.

Introduction: Self-leadership is a psychological concept that display an impressive potential in the enhance of individual performance. The purpose of this study was to examine the perceived levels of use of self-leadership strategies by athletes and to explore the existence of potential individual differences in self-leadership strategies by athletes with and without physical disability. Material and methods: Participants were a sample of 469 athletes, 245 with physical disability and 224 without physical disability (n = 312 men, and n = 157 women). Participants’ ages were 16-51 years old (age 24.82±7.32 yrs). The subjects filled a validated Greek version of the Revised Self-leadership Questionnaire (RSLQ). Results: Results showed some positive self-leadership tendencies, and significant individual differences in the use of self-leadership strategies (self-reward p<0.001; ES=0.029, self-punishment p<0.01; ES=0.017, natural rewards p<0.001; ES=0.026, visualizing p<0.001; ES=0.023, and self-talk p<0.001; ES=0.032) between athletes with and without physical disability. Conclusions: In conclusion, the findings of the present study support that athletes with different physical abilities are not exactly alike in the self-leadership abilities. It is considered useful when a coach is concerned about their athletes’ self-leadership training.
The dangers in a globalising world – selected examples
Authors: Krzyżak Konrad
Published: January 2022

This paper deals with selected dangers in a globalizing world. It outlines the risks associated with socio-economics, culture and civilization. Such description is obviously incomplete and requires further research and deeper analysis. However, the hazards discussed here are definitely real and no solutions for preventing or at least diminishing them have been found so far. For some people globalization is a chance for development, multiplying profits or a decent life, whereas for others it may cause economic regression, poverty or a lack of perspective for a better future. It should all be remembered, the more so the world has never before been so “small”.
On the security of the Republic of Poland at the turn of the 20th and 21st century. It was, is and probably will be fine
Authors: Kościuk Lech
Published: January 2022

The author refers to his reflections from the period 1993–2009. They were included in the studies of the Polish Institute of International Affairs and the institutions of the Ministry of National Defense. He points out that the presented analyzes of the international security in Poland’s vicinity of that time led to the conclusion that the threat of war to Poland in the next 15–20 years is not very similar. Such a conclusion was also included in the penultimate Strategic Defense Review of the 2009–2011 edition of the Ministry of National Defense. The author is of the opinion that the situation of Poland and the political and military conditions mean that aggression against Poland will be tantamount to a conflict on a large scale. Political and military tsunami. A conflict that will involve key actors on the international scene. The author recalls the opinions expressed by Jarosław Kaczyński in 2016.: „(Russia’s) attempt to enter Kiev is definitely a war, and it is a global war. To enter Warsaw is a world war right away”. The study points out that in fact Poland is dominated by a high level of sense of security. Although the perception of the spreading threat from the East dominates the political narrative. Facts are the premises for such an assessment. The adopted program of modernization of the armed forces dates back to 2023. Small amounts of modern weapons are purchased. The implementation of already adopted programs is stretched over time. The amount of old weapons is still significant and will be in use for many years to come. The article indicates that the importance of cyberspace in shaping security and conducting armed struggle is growing. The possibilities of recognizing, using IT tools in targeting and increasing the effectiveness of combat management are dramatically increasing. There are many indications that the ability to recognize targets has gained an advantage over effectors. We are witnessing the development of the ability to act hostile in times of peace, but it is difficult to conclude that this is an indication of an increase in the threat of war.

Authors: Derigny Thibaut , Schnitzler Christophe , Gandrieau Joseph , Potdevin François
Published: January 2022

Purpose: The objective of this study was to examine how adolescents' physical activity (PA) changed during the COVID-19 crisis according to level of intensity and whether there are typologies of resilience based on individual and environmental characteristics. Methods: A longitudinal follow-up study of PA in a representative sample of French adolescents (n=808, 16.32±1.01 years old) was carried out. Two online surveys collecting reported data on amounts of PA were completed the week before and during the first week of the lockdown. Data related to individual and environmental characteristics were collected. A principal component method with qualitative and quantitative data (FAMD) for cluster analysis was performed to identify adolescent’s profiles according to their individual, interpersonal and environmental determinants. Two-way repeated measures ANOVA and a Bonferroni Post-Hoc test were performed to detect any significant effects of adolescents’ clusters on time and each intensity level of PA. Results: Three clusters were identified and characterized by a multifactorial process: active, studious and rural adolescents (37%) reported a significant increase in their MVPA (+707 Mets·week-1, p<0.05), inactive, underachieving and rural adolescents (32%) reported a stability in their MVPA (0 Mets·week-1, NS) and urban adolescents (31%) reported a significant decrease of MVPA (-237 Mets·week-1, p<0.05). Conclusion: This study investigated the multifactorial and temporal complexity of PA resilience according to a socio-ecological anchoring, suggesting that factors of resilience in PA are linked to availability of rural and green environments (environmental determinants), good pedagogical follow up (interpersonal determinant) and high initial involvement in PA (individual determinant).

Aim Present study was conducted with a theme to develop yoghurt spread from goat milk owing to its therapeutic significance and ameliorate nutritional value and quality of the finished product via supplementation of chia seed oil. Methodology Four treatments (T0, T1, T2 and T3) possessing varying concentrations of chia seed oil (0, 2, 4 and 6%) were formulated and the first was opted as control. Samples were evaluated on 0th, 10th and 20th day for physicochemical (pH, acidity, TSS, total protein, fat), microbiological (total plate count) and sensory acceptance. Results Significant changes (increasing or decreasing trends) were perceived in all physicochemical parameters as the storage span progressed however minute differences were observed among different treatments except moisture content which varied significantly among different formulations. Total microbial count also increased with increase in storage days however decreased with increase in concentration of chia seed oil. Sensorial attributes particularly product acceptability was considerably reduced at the end of storage period. Conclusion Generally, addition of chia seed oil at different concentration to yoghurt spread improves the sensory properties and overall acceptability, extends the shelf life and enhances nutrition values. Goat milk is preferable to cow milk owing to essential nutrients it provides to infants and substantial therapeutic significance.

This case report presents the diagnosis of superior mesenteric artery and nutcracker syndromes in a previously fit and well 14-yearold girl. Although these two entities usually occur in isolation, despite their related aetiology, our patient was a rare example of their occurrence together. In this case the duodenal compression of superior mesenteric artery syndrome caused intractable vomiting leading to weight loss, and her nutcracker syndrome caused severe left-sided abdominal pain and microscopic haematuria without renal compromise. Management of the superior mesenteric artery syndrome can be conservative by increasing the weight of the child which leads to improvement of retroperitoneal fat and hence the angle of the artery. The weight can be improved either by enteral feeds or parenteral nutrition. This conservative management initially helped but not in the long-term as the child started losing weight again. The next step in management is surgery (duodenojejunostomy – if the conservative management fails), which the child went through, remarkably improving their symptoms.

Published: January 2022

This study aims to examine the effect of technological innovations on the environmental quality in 1995-2017 for the selected OECD countries and to determine Environmental Kuznets Curve. While carbon emission is the dependent variable, patent applications, GDP per capita, energy use, and urbanization are used as control variables in the model. Second-generation panel analysis has been estimated to examine the link between technological innovations and environmental quality. According to the results obtained, Environmental Kuznets Curve is not valid in selected OECD countries. Technological innovation decreases environmental degradation while energy use and urbanization increase degradations.
Türkiye’de çubuk alüminyum giydirme cephe sistemlerinin tasarım ve uygulama süreçlerinde mimari tasarım – taşıyıcı sistem uyum sorunları
Authors: SABAN Müge , ÖZMEN Cengiz
Published: January 2022

Çubuk alüminyum giydirme cepheler (ÇAGC) Türkiye’de en yaygın kullanılan giydirme cephe sistemleridir. Bu sistemler mimari çeşitlilik sağlamaya elverişli doğaları, modüler yapıları, üretim ve montaj kolaylığı ile ekonomik olmaları gibi pek çok olumlu özellikler sunmaktadır. Mimari özelliklerinin yanı sıra ÇAGC sistemleri yapı taşıyıcı sistemine asılan elemanlar olarak yapılar üzerinde önemli yük etkileri oluşturmaktadır. Bu yük etkileri sadece durağan düşey yükler kadar rüzgar ve deprem gibi önemli dinamik ve yanal etkileri de içermektedir. Ayrıca yük aktarımı tek yönlü de değildir. Yapı taşıyıcı sistemlerinin düşey ve yanal yer değiştirmeleri de giydirme cepheler üzerinde yük etkileri oluşturmaktadır. Bu karşılıklı etkileşimin sağlıklı bir şekilde gerçekleşmesi ÇAGC tasarım ve uygulamalarında verilen mimari kararlar ile yakından ilişkilidir. Yaygın kullanılan giydirme cephe sistemleri oldukları için ÇAGC sistemlerin tasarım ve uygulamalarında mimari hatalara rastlanmaktadır. Bu hatalar genellikle inşaat süreçlerinin geç aşamalarında ortaya çıkmakta ve yapı mimarisi ile taşıyıcı sistem davranışlarını etkileyecek çözümlerin üretilmesini gerektirmektedir. Bu çalışma kapsamında ÇAGC tasarım üretim ve uygulama süreçleri incelenmiş, bu süreçlerde verilen mimari kararların giydirme cephe ile yapı taşıyıcı sistemini nasıl etkilediği araştırılmıştır. Türkiye’de gerçekleştirilen ÇAGC sistem uygulamaları arasından mimari hatalar içeren örnekler seçilerek bu örnekler bazında sorunların nedenleri ve çözüm yöntemleri incelenmiş, sınıflandırmaları yapılmıştır. ÇAGC tasarım ve uygulamalarında hataların önlenmesi için başta mimarlar ve mühendisler olmak üzere bütün paydaşların sürecin başından itibaren beraber çalışmaları gerekliliği vurgulanmıştır.
