ABSTRATO
Introdução: A fadiga é uma condição comum durante a atividade física, resultando em redução da força muscular, controle motor, equilíbrio e coordenação. Mudanças na pressão plantar muitas vezes estão relacionadas à fadiga também podem aumentar o risco de lesão. Hipótese/Objetivo: Avaliar as alterações na baropodometria durante o movimento de agachamento. A hipótese é que a pressão e a carga serão maiores na perna não dominante pós-fadiga Metodologia:Foram recrutados 28 voluntários de ambos os sexos, todos participantes ativos da equipe universitária de vôlei. A distribuição da pressão plantar foi medida durante três movimentos de agachamento. A avaliação foi realizada antes e após o protocolo de fadiga, que consistiu em quatro séries de quinze segundos de salto com dez segundos de descanso entre as séries. A análise estatística foi realizada por meio do pacote estatístico PASW 19.0 (SPSS inc.) com nível de significância adotado de 5% (p ≤ 0,05). Resultados: Para o sexo feminino, houve redução significativa de 12% na pressão média do membro dominante. Para o sexo masculino, reduções significativas na pressão média do membro dominante (7,1%) e membro não dominante (9,5%) e pico de pressão do membro dominante (13,8%) e não dominante (10,1%) . Conclusões:Os processos de fadiga reduziram a pressão plantar durante o movimento de agachamento, apresentando diferentes repercussões entre os sexos, mas ambos capazes de predispor a lesões.

Published: March 2022

La convivencia es un aspecto esencial en los centros educativos por su contribución a la creación de un clima de trabajo adecuado para el alumnado y profesorado. Desde una propuesta que integra la elaboración democrática de normas, los equipos de resolución de conflictos y un marco protector de la convivencia, se busca diseñar y validar un instrumento para medir su percepción en el profesorado. Se aplicó un cuestionario a 432 profesores de Educación Infantil, Primaria y Secundaria Obligatoria de la Comunidad de Madrid, cuyos datos fueron sometidos a análisis factorial exploratorio y confirmatorio. Los resultados configuraron un instrumento de valoración en torno a cuatro factores: Marco protector de la convivencia, Programa de Mediación, Programa de Alumnos Ayudantes y Proceso democrático de elaboración de normas. Dichos factores fueron capaces de explicar el 62,78% de la varianza como indicador de la validez de constructo. La fiabilidad resultó adecuada para la totalidad del cuestionario (α = ,810). La validez de constructo quedó confirmada en análisis posteriores (CMIN/DF = 2,597; CFI = ,926; RMSEA = ,061). Aquí se ofrece un instrumento con valores adecuados de fiabilidad y validez que posibilita la valoración de la convivencia por parte del profesorado desde una perspectiva integrada.

Combined damage to the knee ligaments and the coxofemoral nerve
Authors: Sukhonosenko V. M. , Міan A. A.
Published: March 2022

The examination and treatment of 25 patients with chronic combined damage to the knee ligaments and the coxofemoral nerve have led the authors to the conclusion that many patients are not diagnosed as having nerve injury in the early period. Early diagnosis of combined damages makes it possible to perform treatment in time in recovering the ligaments and nerve function and to rule out intricate reconst motive operations in the late period of injury. In chronic combined damages to the ligaments and the nerve, the most justifiable therapeutical method is surgery: plastic recovery of the ligaments and revision of the nerve, which is expedient to make simultaneously, the scope of an operation on the nerve is determined by the nature of a damage. Positive clinical results seen among most patients confirmed the efficiency of the therapeutical method.

Published: March 2022

The diagnostic potentialities of coronary computed tomography (CT) (23 patients) and zonography (25 patients) were evaluated by analyzing the results of examinations. Zonography is largely indicated in limited mobility of the neck. Coronary CT requires sufficient cervical mobility. The latter method has a high resolution and allows one to diagnose abnormalities undetectable during routine X-ray examination. Zonography and coronary CT substantially elevate the quality of diagnosis in various injuries and diseases of the upper spine.

The results of testing the hypotheses put forward in the work suggest that, firstly, foreign measures are poorly applicable to eliminate sabotage by Russian officials and there is a need to develop individual measures to combat sabotage in the Russian civil service. Secondly, purposeful work on a systematic fight against sabotage of civil servants is not yet being carried out. The extremely poor knowledge of the identified problem set tasks aimed at expanding the objects of research, drawing conclusions about the current state of sabotage in the domestic civil service. The main results were obtained by analyzing the literature and researching surveys of civil servants at the federal and regional levels, conducted by other scientists. At the same time, the emphasis is on studying the opinions of experts, former and current officials, and on their basis, conclusions are drawn about the current state of sabotage in the Russian civil service. As a result, new and refined measures are proposed to combat sabotage of Russian civil servants (organize courts of honor; eliminate overtime unpaid work of civil servants; adjust the regulations for the work of officials; provide non-material benefits to civil servants that reduce the value of rest for them; introduce classical schemes for combating shirking in the civil service, borrowing them from commercial structures; to reduce staff turnover; to increase the attractiveness of the civil service; to establish standards for anti-sabotage behavior). It seems that the questions raised in this article will allow future researchers to better understand the directions of potential research in the field of sabotage of officials, to compose representative questionnaires and identify the right questions for in-depth interviews of civil servants in this area, to develop other measures to improve the management of civil service in the Russian Federation.

Authors:   Southern Federal University, Nikitaeva Anastasia Y. , Salem Abdel-Badeeh M. ,   Ain Shams University
Published: March 2022

The article is devoted to the institutions of dissemination and application of artificial intelligence in industry. Artificial intelligence (AI) is currently one of the most dynamically developing technologies and outcomes of the Fourth Industrial Revolution with a huge transformational impact on the economy. The article further confirms the inclusion of this technology in all industrial frontiers of recent years. In industry, artificial intelligence has a high potential of use with prodigious positive effects, but this potential and positive results are limited by insufficiently designed institutional framework for the development of artificial intelligence. To establish a way of institutionalizing AI in industry, the article systematizes the drivers and limiting factors of its cost-effective deployment in industrial companies. Based on this, the authors outlined a conceptual institutional framework for artificial intelligence in industry, including institutions of different levels as well as formal and informal institutions. The stimulating and limiting function of institutions in the deployment of AI is considered from the strategic perspective and operational regulation. The article substantiates the priority of artificial intelligence legislation, which goes beyond both individual countries and institutional conditions focused on a specific technology. It is necessary to develop the digital economy, activate innovations, create a competitive environment, etc. The authors have confirmed the importance of a broader institutional context of economic and technological development in the context of Industry 4.0. The article also pays attention to industry standards and ethical standards for the dissemination of artificial intelligence. At the same time, the influence of the institute of trust, partnerships, and digital corporate culture on the adoption and deployment of artificial intelligence technologies in industrial companies is taken into account. It is determined that, to understand and accept AI (include it into decision-making processes and business practices), institutions are required to make technologies more understandable for perception.
The Multitaper Spectrum Analysis Package in Python
Authors: Prieto Germán A.
Published: March 2022

Spectral analysis has been a fundamental tool in analyzing seismic signals for studying the earthquake source, propagation of seismic waveforms through the Earth, and even monitoring changes in Earth’s structure. I present an open-source Python package, multitaper, for spectral analysis using the multitaper algorithm. The package not only includes power spectral density estimation (with confidence intervals) but also includes bivariate problems such as coherence, dual-frequency correlations, and deconvolution estimation. Implementation of the sine and quadratic multitaper algorithms is also available. For the reader to quickly learn how to use the package, I briefly present several examples using earthquake records from the 2019 Mw 6.0 Mesetas, Colombia, earthquake and its aftershocks recorded at regional distances for estimating time–frequency spectrograms, spectral ratio and source time functions, and correlations between neighboring frequencies. Jupyter Notebooks are shared to reproduce the figures.

Authors: TURGUT Oğuz Emrah , ASKER Mustafa
Published: March 2022

In this study, convective boiling behaviors of refrigerants (R22, R134a, R290, R404a, R410a, R600, R507, R717, and R744) are compared with existing flow boiling correlations. Flow boiling heat transfer rates under the primary influences of vapor quality and mass flux are plotted and compared with the experimental results that are extracted from the literature. A statistical approach is introduced for error analysis and a valid correlation is proposed for each refrigerant. Correlation of Wojtan et al. with 30% of experimental data in 20% error region is selected as the best correlation while Shah Correlation with 10% of experimental data in 20% error regions performs the worst. The result of the analysis indicates that flow boiling heat transfer values are strongly dependent upon mass velocity and heat flux. It is observed that existing correlations are in good agreement with experimental works at low heat flux rates whereas deviations are getting bigger for high heat flux rates.

Authors: Çetiner Mustafa , Akdağ Gönül , Akkoyun Arikan Fatma , Canbaz Kabay Sibel
Published: March 2022

Myasthenia gravis (MG) is an autoimmune disease that is characterised by the formation of antibodies against acetylcholine receptors in the postsynaptic membrane of the neuromuscular junction. The course of the disease cannot be predicted during pregnancy. A subtype of MG with positive muscle-specific receptor tyrosine kinase (anti-MuSK) antibodies exhibits more localised clinical characteristics and a poor response to treatment compared with the disease subtype that involves positivity for acetylcholine receptor antibodies. Myasthenic crisis is more frequently observed in anti-MuSK-positive myasthenia patients. Anti-MuSK-positive myasthenic crisis management is very difficult and a risky situation during pregnancy. The reported case was 30 years old, female, 9 weeks pregnant and musk antibody positive. She stopped her treatment without asking her doctor because she was planning pregnancy in the 6-month period before her hospitalization. She was intubated for a long time in the intensive care unit due to myasthenic crisis and was very resistant to treatment. During this period, her pregnancy was terminated due to fetal anomaly. Plasmapheresis, IVIg and immunosuppressive treatments were applied. Our patient was discharged after a period of about 10 weeks. We share our treatment management.

Published: March 2022

This paper presents a pedagogical study on the need for applying a "Handbook of reference points" in undergraduate midwifery students’ theoretical material in a digital learning environment. Although interactive learning methods in a digital environment are evaluated as fully effective, we demonstrate the necessity of using paper-based information resources. By means of an entry and a final test control, the success rates of the observed student groups are summarized and compared, which are transformed from the student's obtained grade. Statistical processing was performed with the STATISTICA 10 package (with the ANOVA module). Analysis of variance was performed on the collected data. The findings are significant for health care educators who face many challenges in a digital learning environment. It is concluded that with the use of the "Handbook of reference points" in the virtual room, students increase their practical training com petencies.
Mathematical delay model based on QS with hyperexponential and Erlang distributions
Authors: Tarasov Veniamin N.
Published: March 2022

This article is devoted to the study and obtaining a closed-form solution for the average delay of claims in the queue for a queuing system formed by two flows with hyperexponential and Erlang distributions of intervals. The combination of these distribution laws provides the coefficient of variation of the input flow intervals large units, and for the service time - less than unity. Considering the coefficients of variation as numerical characteristics in the queuing theory is important, because the main characteristic of the queuing system is that the average delay is related to these coefficients of variation by a quadratic dependence. In queuing theory, studies of G/G/1 systems are relevant due to the fact that they can be used in modeling data transmission systems for various purposes. To solve the problem posed, the method of spectral decomposition of the solution of the integral Lindley equation was used. This method made it possible to obtain a spectral decomposition, and through it a solution for the average delay of requests in the queue for the system under consideration in a closed form. For the practical application of the results obtained, the method of moments of the theory of probability was used.

Authors: Zuev Maxim Yu.
Published: March 2022

This article presents the results of modeling a communication system with OFDM using the methods of scrambling the transmitted signals and masking the transmitted information. The paper considers a method of scrambling the transmitted information with pseudo-random sequences obtained by a generator built on the basis of modified dynamic systems. Estimates of the probability of a bit error of the communication system under consideration are obtained, the peak-factor of signals, the correlation characteristics of the scrambled and initial information are estimated, and the entropy of the transmitted information. The results of the article can be used in the design of modern communication systems in order to increase the security of transmitted information and reduce the peak to average power ratio of the generated signals.

Authors: PARLAK Ayşe Eda , YAĞCI Buket
Published: March 2022

Objectives: The purpose the study was to evaluate the role of diffusion weighted magnetic resonance imaging (DW-MRI) in diagnosis of benign and malignant breast lesions, to calculate a cut-off apparent diffusion coefficient (ADC) value and to explore use of relative ADC (r ADC) for improving sensitivity and specificity of MRI in diagnosis of breast cancer.
Methods: This retrospective study based on a cohort of patients who underwent dynamic contrast enhanced (DCE)-MRI having suspicious breast mass by ultrasonography and mammography to whom DWI sequence was added to the routine diagnostic MRI. ADC and r ADC (lesion/normal breast tissue) values of breast masses were calculated. The threshold ADC values used to differentiate benign and malignant lesions were determined using receiver operating characteristic analysis, sensitivity, specificity, positive predictive value and negative predictive value were calculated.
Results: Malignant masses had significantly lower ADC (mean: 1.03 ± 0.36 × 10-3 mm2/s) and r ADC (mean: 0.66 ± 0.22 × 10-3 mm2/s) values than those of benign masses with ADC (mean: 1.50 ± 0.56 × 10−3 mm2/s) and r ADC (mean: 0.97 ± 0.31 × 10-3 mm2/s) values, respectively (p = 0.001 for both). The best cut-off value for the lesion ADC was 1.09 × 10-3 mm2/s with a sensitivity of 72.73%, and specificity of 79.17%. The best cut-off value for r ADC was 0.83 with sensitivity of 78.79% and specificity of 70.83%.
Conclusions: DWI has high diagnostic value with high sensitivity and specificity differentiating benign and malignant breast lesions. ADC and r ADC values can improve the diagnostic accuracy of differentiating benign and malignant breast lesions.
Z klasy robotniczej do pomocy społecznej. Biograficzne doświadczenia dawnych „beneficjentów socjalizmu” w postindustrialnym polskim mieście
Authors: Golczyńska-Grondas Agnieszka , Potoczna Małgorzata
Published: March 2022

Od początku lat 90. socjologowie z Uniwersytetu Łódzkiego prowadzą wielowymiarowe badania biedy i wykluczenia społecznego. W latach 1997–1999, w ramach projektów „Formy ubóstwa i zagrożeń społecznych i ich przestrzenne rozmieszczenie w Łodzi” (1997–1999) oraz „The Social Cost of Economic Transformation in Central Europe: Social History of Poverty in Central Europe – The Polish Case” (1999), przeprowadzono wywiady typu family life histories z trzema generacjami rodzin wspieranych przez pomoc społeczną. W PRL-u narratorzy reprezentujący „podstawową” generację badanych (40–50-latkowie) zaliczani byli do klasy robotniczej i reprezentowali zbiorowość, którą w pewnym sensie określić można mianem „beneficjentów socjalizmu”. W okresie realizacji badań przeżywali oni traumatyczne trajektorie wywołane przez procesy pauperyzacyjne. W artykule powracamy do danych sprzed prawie 20. lat i przedstawiamy biograficzne doświadczenia narratorów w odniesieniu do ich subiektywnego rozumienia procesu transformacji. W ostatniej części artykułu odwołujemy się do badań powtórzonych, przeprowadzonych w latach 2008–2010, wskazujemy na makrostrukturalne uwarunkowania losów badanych rodzin i na czynniki znaczące dla podtrzymywania błędnego koła biedy i marginalizacji społecznej.
Participatory Methods: the Exemplary Case of the Bela Vista “Island” in Porto (2013-2017)
Authors: Silva Manuel , Rodrigues Fernando , Fontes António Jorge , Fontes André
Published: March 2022

The authors summarize the origin and evolution of the urban “island” of BelaVista in Porto, Portugal, since the 19th century. Despite local residents mobilizing in the wake of the revolution of April 25th 1974 in the context of the urban housing and design initiative (Local Ambulatory Support Service — Serviço de Apoio Ambulatório Local, SAAL), they were unable to renovate the crumbling neighbourhood. The Residents’ Association, resisting the onslaught of demolition strategies that were driven by real estate interests, eventually managed, with the support from a technical team of architects, social scientists and activists, to mobilize residents and ensure the political commitment of an independent parliamentary candidate in order to rehabilitate the “island” of Bela Vista. The project was also subsequently supported by the Councillors of Culture and Urbanism. Though various quantitative (survey) and qualitative (interviews, life stories) methods were applied in the study, the article highlights and expands on the action-research method opposite to positivist assumptions.
Phenomenological Enthymeme in V.N. Voloshinov’s Marxist Sociology of Poetics. Using the Example of an Article titled “Word in Life and Word in Poetry...”
Authors: Malinkin Alexander
Published: March 2022

On the example of the article “Word in Life and Word in Poetry. On the Issues of Sociological Poetics” (1926), the author analyzes the sociological methodology used by V.N. Voloshinov (M.M. Bakhtin) in a number of publications in the 1920’s and first utilized in this article. The methodology is declared to be Marxist. It is proven that it cannot be unequivocally identified with the Marxist variety, since it does not fully correspond to the fundamental principles of the teachings of K. Marx and F. Engels. The Voloshinov-Bakhtin methodology reveals a conceptual and subject-thematic affinity with Max Scheler’s phenomenological sociology. The author believes that the article attempts to combine two philosophical methodologies within a single humanitarian-scientific study. A double comparative analysis is conducted by the author in the context of the results of researching the life and work of M.M. Bakhtin in order to expand the cultural and scientific research space in the history of Russian philosophical sociology.

Published: March 2022

Everybody has the right to get an education; a student with autism spectrum disorder (ASD) is no exception. The researcher had an ASD student in his Curriculum and Material Development class. It turned out that the student struggled to comprehend and memorize the materials. Therefore, the researcher decided to use mind maps to assist him. Action research was conducted to investigate the challenges and benefits of using mind maps. The research employed three gathering techniques namely, observations, content analysis, and an interview. The findings suggest that the ASD student often forgot how to make an effective mind map and he found it difficult to make a mind map without getting any help. Hence, repetitions and assistance from lecturers in making mind maps are of utmost importance. With the help of the lecturers, the ASD student found it easier to comprehend and memorize the materials.

Numerical Simulation and Mechanism Investigations of Cavitating Noise Around a Two-Dimension Valve Pilot Stage
Authors: Yonghua Zhao , Jian Ruan , Qianqian Lu
Published: March 2022

The two-dimensional valve integrates the pilot stage and the power stage on one spool, which makes it easy to achieve a fast valve operation and a high frequency response. It has the advantages of simple structure, stable performance and high power to weight ratio. In this paper, the fluid flow in the pilot stage of a 2D valve is analyzed by computational fluid dynamics, and the influence of cavitation on the flow field in the valve is the main study objective. The result shows that the throttling action of the valve port forms a high-speed jet in the chute area of the valve sleeve, and a large area of cavitation cavitation is generated at the same time. The velocity vortex and cavitation work together to intensify the pulsation of the fluid in the valve and become the main source of the noise. In the 2D valve pilot stage, the sound pressure level at the back of the chute of the valve sleeve reaches 175dB, and the maximum sound pressure level at the middle and outlet reaches 168dB. The sound pressure level at the back and middle of the chute decreases first and then increases, and the sound pressure level at the outlet of the chute decreases slowly. In the range of 0 - 5000Hz, the noise energy is concentrated in the low frequency band of less than 1000Hz, showing typical cavitation noise characteristics. The numerical result is favorable with the experimental result.

The suspension system plays a major role in automobiles to improve passenger comfort, passenger safety and road handling. It isolates the body of a vehicle from road disturbances. The full vehicle would be subjected to disturbances from all four wheels or a full suspension model of the vehicle and, thus, a full-suspension model of the vehicle should be added to the idea of an enhanced control preview. The input data for the fuzzy logic controller (FLC) is the velocity and acceleration of the front and rear wheels. Controller outputs are considered to be active forces that improve driver comfort, safety and road handling characteristics. The objective of this work is to model and analyse an active full vehicle suspension. The model is optimized using advanced FLC to improve driver comfort, safety and road handling. The mathematical model for the active full vehicle suspension model has been derived. The necessary background for the Simulink fuzzy logic and FLC has been presented. All the simulations are carried out using MATLAB/SIMULINK, a high-performance numeric computation and visualization software package. The fuzzy logic-controlled active values have been compared with ordinary passive simulated values for road profiles. The result of the simulation show that the designed advanced FLC has improved ride comfort by effectively reducing the vehicle body displacement. There is also an appreciable reduction in velocity and acceleration with no increase in suspension travel.

To achieve good performance of fault feature extraction for a rolling bearing, a new feature extraction method is presented in this paper based on local maximum synchrosqueezing transform (LMSST) and global fuzzy entropy (GFuzzyEn). First, targeting the time-varying features of the vibration signals of the rolling bearing, the LMSST algorithm, which is a newly developed time-frequency method and allows for adaptive mode decomposition, is used to preprocess the vibration signals into a number of mode components. Then, as a modification of FuzzyEn, GFuzzyEn is adopted to evaluate the complexity of these mode components. Compared to FuzzyEn, which focuses mainly on the local characteristics of the short-term physiological time series, the GFuzzyEn emphasizes the global characteristics of the signal considering that the bearing vibration signals' global fluctuation may change as the bearing works under various conditions. Finally, the fault features of the bearing vibration signals are extracted by combining the LMSST and the GFuzzyEn. The experimental analysis shows that the proposed LMSST-GFuzzyEn method can extract rich fault-related information from the bearing vibration data and can achieve good classification performance for rolling bearing fault diagnosis.
Why Do Elementary Particles Have Such Strange Mass Ratios? - The Role of Quantum Gravity at Low Energies
Authors: Singh Tejinder P.
Published: March 2022

When gravity is quantum, the point structure of space-time should be replaced by a non-commutative coordinate geometry. This is true even for quantum gravity in the infra-red. Using the octonions as space-time coordinates, we construct a pre-spacetime, pre-quantum Lagrangian dynamics. We show that the symmetries of this non-commutative space unify the standard model of particle physics with $SU(2)_R$ chiral gravity. The algebra of the octonionic space yields spinor states which can be identified with three generations of quarks and leptons. The geometry of the space implies quantisation of electric charge, and leads to a theoretical derivation of the mysterious mass ratios of quarks and the charged leptons. Quantum gravity is quantisation not only of the gravitational field, but also of the point structure of space-time.

Published: March 2022

Objectives. To determine how harm reduction should be applied in low-resource countries such as Vietnam by exploring the perspectives of people who use drugs (PWUD), health care professionals, and policymakers regarding methadone treatment and harm reduction strategies.

Methods. We conducted 2 qualitative studies in Vietnam between 2016 and 2021. We interviewed 62 PWUD and 22 experts in drug policy development and drug treatment programs, conducted observations at methadone clinics and harm reduction program meetings, and analyzed drug policy documents.

Results. PWUD considered methadone treatment only as a transition to a drug-free life. Policymakers deemed harm reduction ineffective and continued to enforce arrest and incarceration of PWUD. Drug intervention programs are not yet geared to providing specialized services. Effective communication strategies and information on evidence-based harm reduction models are inadequate to help policymakers make the right decisions.

Conclusions. Harm reduction principles have not been fully adopted in Vietnam. A harm reduction strategy based on a more humanistic approach that goes beyond a biomedicalized approach is urgently needed in Vietnam and other countries in the Global South.

El Impacto de la Pandemia por COVID-19 en Población Infanto-juvenil española con Trastorno del Espectro Autista y en su familia
Authors: Prieto Navarro Irene
Published: March 2022

La pandemia causada por la enfermedad infecciosa por coronavirus-19 (COVID-19) desencadenó el aislamiento a nivel mundial, afectando en peor medida a las personas con Trastorno del Espectro Autista (TEA). El objetivo de esta investigación es conocer cómo ha sido este impacto a nivel conductual, emocional, social y comunicativo y la repercusión que ha tenido en sus familias. Para ello se utilizó un cuestionario “ad hoc” durante y después del confinamiento, el Cuestionario de Capacidades y Dificultades (Strengths and Difficulties Questionnaire, SDQ) (Goodman, 1997) y la Escala Miedo al COVID-19 (Martínez Lorca et al., 2020). Este cuestionario fue respondido por 140 padres y madres basándose en el comportamiento de su hijo o hija diagnosticado de TEA, con una edad media de 7,86 años, y procedentes de diferentes comunidades autónomas de España. Los resultados reflejan como los participantes, durante el periodo de confinamiento, han mostrado flexibilidad a los cambios de rutina, pero un alto nivel de estrés, irritabilidad, dificultades conductuales y sociales y regresión en las habilidades anteriormente adquiridas, presentando también dificultades para entender lo que ocurría y expresar lo que sentían. Además, presentaron dificultades para aplicar las medidas de seguridad impuestas, como el uso de la mascarilla, del gel hidroalcohólico y el distanciamiento interpersonal. Las familias han referido un excesivo estrés y miedo, así como han echado en falta algunos apoyos y servicios de ayuda.
