UTILIZAÇÃO DO PBL (PROBLEM BASED LEARNING) COMO METODOLOGIA DE ENSINO APOIANDO-SE EM PESQUISA DE MESTRADO COMO EVIDÊNCIA PARA REFLEXÃO DOS OBJETIVOS DA AGENDA 2030
Authors: de Oliveira José Donizeti
Published: September 2021

Atualmente algumas escolas e professores, diante das dificuldades enfrentadas em sala de aula para conseguir a atenção e, consequentemente, os interesses de seus alunos, tem buscado algumas alternativas aos métodos convencionais de ensino, e uma delas é por meio da utilização do método Aprendizagem Baseado em Problemas, ou Problem-based Learning - PBL, em inglês. Desta forma este trabalho tem como objetivo mostrar a importância da aplicação desta metodologia de ensino, em especial, mostrar o que está pode trazer para todos os níveis da educação na busca de soluções para os 17 Objetivos de Desenvolvimento Sustentável da ONU, presentes na Agenda 2030, assim como os professores podem promover uma reflexão dos estudantes sobre essas propostas e buscar soluções. Os resultados esperados são aqueles que possam trazer para todos os níveis de ensino agregação de valores pessoais por meio de experiências vivenciadas nessas dinâmicas em sala de aula. Sabe-se que uma das metas do Centro Paula Souza é proporcionar aos seus alunos além de uma formação profissional, prever que este tenha oportunidades para, além do desenvolvimento científico e tecnológico, realizar exercícios de cidadania. A metodologia utilizada foi a de pesquisa bibliográfica em Teses, Dissertações e ou Artigos da história, origem, aplicações e resultados do PBL que possam servir de base para que se possa refletir como a educação pode contribuir para o conhecimento, disseminação dos objetivos da Agenda 2030, assim como evidenciar exemplo de pesquisa de mestrado em 2019 que mostra resultados obtidos de um estudo realizado sobre a formação da mulher em cursos técnicos. Com essa proposta, busca-se criar um ensino problematizador, que possa preparar o aluno não só para o mercado de trabalho, mas para uma sociedade melhor que busca diminuir as diferenças em todos os níveis. Para se conseguir ótimos resultados nos métodos PBL, serão necessários esforços de todos os atores envolvidos neste método, atuando como mediador, o professor, o estudante como principal responsável por sua aprendizagem e a escola colaborando para que a proposta de abordagem seja realizada.

Published: September 2021

Este estudo apresenta a utilização de agregados miúdos reciclados de resíduos de rochas ornamentais aplicados em concretos estruturais, tendo como objetivo avaliar as características físicas e mineralógica, tal como a influência da inserção desse tipo de agregado nas propriedades mecânicas de consistência e resistência à compressão axial dos concretos produzidos. Para tal, foram confeccionados concretos por meio de uma dosagem experimental, com um traço de referência com relação aglomerante: agregados secos de (1:5) e abatimento fixo de 100±20 mm. Para isso, foram produzidas três misturas com os teores de 10%, 20% e 50% de resíduos de rochas ornamentais em substituição ao agregado miúdo natural. A princípio, realizou-se a seleção e caracterização física dos materiais, para em seguida dar continuidade às etapas de dosagem, confecção, moldagem e cura dos concretos. Para os concretos produzidos, avaliou-se o índice de consistência e a resistência à compressão axial aos 7 e 28 dias de idade. Por meio da análise dos resultados, constatou-se que os concretos confeccionados com resíduos de rochas ornamentais apresentaram resistência à compressão simples maiores que o concreto de referência, com exceção do concreto com teor de 50% de substituição. Os concretos com teores de substituição de 10% e 20% apresentaram os melhores resultados de resistência à compressão axial em comparação ao concreto de referência, com ganhos médios ao 28 dias de idade de 6,02% e 0,24% respectivamente. Concluiu-se que, quanto às características estudadas, a utilização de resíduos de rochas ornamentais em substituição ao agregado miúdo, em até 10% de massa, melhora o desempenho mecânico do concreto.

Published: September 2021

The current-voltage and lux-ampere characteristics, as well as the photovoltage spectra and the lux dependence of the photovoltage in the gate and photodiode modes of the p-TlGaSe2 - p-CuInSe2 heterojunction obtained for the first time are studied. It was found that this heterostructure has a pronounced diode character. The I - V characteristic of the structure under study is characterized by the fact that at low voltages it obeys well the law I ~ exp (eU / βkT). The photovoltage spectrum covers a wide range of wavelengths (0.55 - 1.85 µm). In this case, pronounced maxima are observed at λ = 0.59 and λ = 0.95 μm. The relaxation time τ determined from the kinetics of the photo-voltage in the valve mode is ~ 20 μs.

The widespread spread of infection caused by the Epstein-Barr virus (EBV), the lack of registered vaccines, the possibility of implementing a transmission mechanism in medical organizations, determine disinfection as the main method of preventing this disease. The aim is to evaluate the effectiveness of chemical disinfection agents approved for use in the Russian Federation in relation to EBV-infected cell culture with quantitative DNA determination by polymerase chain reaction. Working solutions of complex disinfectants used for the treatment of medical devices were introduced into samples of EBV-infected B-cell culture in the concentration and exposure specified in the instructions (0.1 %; 60 min.). Then, the quantitative determination of the EBV DNA was performed. Chlorine-containing disinfectants, combined preparations based on aldehydes and guanidines per hour, as well as guanidines per hour and triamines, provided complete destruction of genetic material, while the combination of H with triamines led only to a decrease in the concentration of EBV DNA from 5.0 · 106 copies/ml to 2.4 · 106 copies/ml (by 2.1 times), which may not be enough to fully ensure biological safety when processing medical devices (sensors of ultrasound diagnostics devices, etc.), which are not subject to sterilization. The inability to determine the viability of EBV after treatment with disinfectants due to the initial presence of the virus in the B-cell culture makes the molecular biological method the only acceptable one at this stage and requires the search for new models – cell cultures intact to EBV or biological objects (laboratory animals). Keywords: Epstein-Barr virus, disinfection, quaternary ammonium compounds, triamines, aldehydes, guanidines, active chlorine releasing agents.

When eating poisoned baits based on 0.1–1.0 % pyriproxyfen, within 6 weeks killed up to 50 % of German cockroaches of the S-NIID strain, and 12 % of cockroaches of the OBN strain. The resulting oothecae turned out to be defective and the second generation of cockroaches did not hatch. Morphological changes consisted were in the deformation of the wings (rudimentary, curved, twisted) and in the inability of the larvae to transform into adults. In experiments with an alternative food, similar results were obtained, females formed more oothecae, but the emergence of new generation larvae was not recorded. The consumption of pyriproxyfen-based baits by Pharaoh ant led to the elimination of colonies. A significant decrease in brood number was recorded at 3–6 weeks, and complete death of brood was observed at 6–8 weeks in all treated colonies. The absence of brood can be explained by both mortality as a result of developmental disorders and the cessation of egg laying by queens. Keywords: insect growth regulators, German cockroach, Pharaoh ant, pyriproxifen, hydroprene.

Authors:   , Gutiérrez Carlos Abel
Published: September 2021

Esta tesis doctoral, dirigida por el Dr. Fernando Jaume y co dirigida por la Dra. Silvia Lázaro, es el resultado de un proceso de investigación de más de 10 años, que tiene como objeto de estudio el sector de la construcción en Misiones y la obra pública (OP), en las décadas de 1990 y 2000. A partir de la verificación cuantitativa de una expansión inédita de la actividad y la inversión pública en infraestructura, que transformó la élite económica local, se analiza la conformación del campo de la OP. Se verifica un cúmulo de reglas no formalizadas en una pirámide empresarial estratificada, dominada por firmas con trayectoria en convivencia con nuevos colegas, en muchos casos alentados políticamente. Pese a la gestación y consolidación de nuevos ámbitos privilegiados de acumulación, la agenda de obras es controlada desde el estado provincial, muy imbricado con gobiernos de un frente transversal notablemente exitoso en términos electorales.

Structural Distortions: Re-examining State Capture and Apprising its Persistence and Effects
Authors: Longhurst Kerry
Published: September 2021

Moldova is a textbook-plus case of a captured state, a condition synonymous with a number of post-Soviet countries. Moldova’s state capture resulted from its post-1991 partial reform path which enabled the emergence of oligarchs able to seize core state functions and distort business environments to the detriment of the public good. Moldova is significant because of the extremity of its state capture with a single oligarchic network shaping the rules of the game in political, economic, social and to a degree foreign policy terms. This situation created a vicious circle, which hindered Moldova’s development, reinforced poverty and the hollowing out of the state through mass migration. 2021 offers a vantage point to consider whether Moldova can shed its capture via the anti-corruption reform programme set out by president Maia Sandu or whether prospects for change are more likely to be impeded by persistent vested interests keen to keep the status quo. Future remedies for Moldova hinge on there being palpable socio-economic improvements to people’s lives, twinned with successful prosecutions of those responsible for large-scale acts of corruption and embezzlement. Aside from this, reforms need to hone in on improving the business environment, the weaving in of women’s empowerment and providing solutions to stem outwards migration.
Oligarchia a wybory parlamentarne w Republice Mołdawii w 2019 r.
Authors: Bacewicz Kinga
Published: September 2021

Parliamentary elections in the Republic of Moldova were held on 24 February 2019. According to domestic and international observers, the election results did not reflect the real preferences of Moldovan voters. This assessment was a result of numerous violations (such as buying votes and abusing administrative resources) and political manipulation made by Moldovan oligarchs and political parties, subordinated to the oligarchs. In this situation, establishing a majority government was impossible, leading to a temporary period of dual power. The political deadlock was finally broken by the unanimous efforts of the Russian Federation, the United States and the European Union. The international intervention deprived Vlad Plahotniuc of his hegemonic political influence. The oligarch left Moldova and the power in the country was taken over by a new coalition government composed of the socialists and the opposition bloc ACUM. However, this change did not lead to the democratisation of Moldovan political life. After only a few months, the role of the political hegemon was taken by the pro-Russian president Igor Dodon. Therefore, the postulate of the deoligarchisation of Moldova, which was used for several months by national and foreign media, only served to change the person in the position of the main political leader.

Published: September 2021

Aim. The presented study aims to harmonize the understanding of the innovative growth of the virtual economy within the framework of a regulatory approach from the perspective of the evolution of regulatory mechanisms.Tasks. The authors identify the major conditions and elements of the virtual economy; clarify the definition of the virtual economy; determine the essential characteristics of the innovative growth of the virtual economy; develop a multidimensional matrix of tools for measuring the innovative growth of the virtual economy within the framework of a regulatory approach.Methods. This study uses the methods of scientific analysis and synthesis as well as comparative and systems approach to examine the reflection of innovative growth in the evolution of regulatory mechanisms that determine economic behavior.Results. The acceleration of economic virtualization during the 2020–2021 pandemic has exacerbated the need for a scientific analysis of the ways and directions of innovative economic growth with allowance for intangible, primarily virtual factors, which include traditional symbolic components implemented on the basis of digital tools. The conducted analysis makes it possible to identify four main dimensions that determine directions for the innovative growth of the virtual economy: adaptation to new categories of entities to the extent of personification based on big data; development of new behavioral models; development of institutions and ecosystems; prioritization of a meaningful requirement for harmony and aesthetics on the part of users.Conclusions. A study of the multidimensional model of innovative growth of the virtual economy will make it possible to improve both the decision-making of individual and group entities, and the regulatory mechanisms used by the government.

Authors: Naugolnova I. A.
Published: September 2021

Aim. The author aims to develop an original methodology for a process approach to cost management at manufacturing enterprises. Its core idea is the possibility of increasing overall enterprise efficiency and reducing costs by using internal reserves identified as a result of business process optimization.Tasks. According to the author, a process approach to cost management is future-oriented and has not yet been properly developed — hence the goals of developing and improving the theoretical and methodological foundations of its implementation.Methods. The methodology for a process approach to cost management is based on the most effective (from the author’s perspective) elements of such methods as “ABC-costing”, “Value chain concept”, “Cost-drivers”, “Target-costing”, “Kaizen-costing” with the author’s additions.Results. The author’s methodology for a process approach to cost management with regard to manufacturing enterprises is presented in the form of a structural and logical scheme. Its elements allow the reader to understand which methods, means, principles, and techniques can be used for its introduction and implementation. The fundamental basis of the methodology for a process approach to cost management is the author’s vision and definitions of the “object” and “subject” of cost management. The conventional structure of the representation of elements in the methodology is supplemented by the following units: “The form of implementation and organization of a process approach to cost management” and “Periods”.Conclusions. A process approach to cost management combines several of the most effective methods of cost management and accounting, making it possible to bring the level of expenses of an enterprise down to a competitive level using the internal reserves of the enterprise.

Published: September 2021

Intent Based Networks (IBNs) are mainly used to transform a user's intent into network configuration, operation, and maintenance strategies. IBN is a prominent feature for designing the AI-enabled next generation networks. In this paper we propose intent-driven orchestration of cognitive autonomous RAN for managing network control parameters.

Our proposed design enables the Controller to detect and remove contradiction, which may arise from a single intent, in the runtime. We also provide a brief overview of existing standards on this aspect and standardization impact of our research to show that it conforms with the worldwide mobile network management standardization efforts.
On the integration of reconfigurable intelligent surfaces in real-world environments
Authors: Díaz-Rubio Ana , Tretyakov Sergei
Published: September 2021

The use of reconfigurable intelligent surfaces (RISs) for optimization of propagation channels is one of the most promising and revolutionizing techniques for improving the efficiency of the next generation of communications systems. In this work, we combine the physical optics approximation and the theory of diffraction gratings to study the scattering properties of finite-size metasurfaces mounted on partially reflecting walls and illuminated by directive antennas. We consider both reflective and refractive metasurfaces designed to control both reflection and transmission of waves. We start the analysis under the assumption of uniform, plane-wave illumination, and then discuss non-uniform illuminations by directive antennas.
Comprehensive Analysis On A New Type VR-Resolver with Toroidal Windings Under Healthy and Eccentric Cases
Authors: Naderi Peyman
Published: September 2021

A novel analysis for a new type Variable Reluctance Resolver (VR-Resolver) with toroidal windings is presented in this work. The resolver with various windings configurations as well as different rotor structures is considered for analysis. Position error of the resolvers in both healthy and eccentric cases are studied, where the effect of the eccentricity fault is analyzed for the resolvers with various windings configuration and rotor shapes. Hence, the analysis of the manufacturing tolerance due to the eccentric rotor is obtained by several analyses. Noticing the Magnetic Equivalent Circuit (MEC) method’s flexibility as well as in regards to the analysis of the several structures, a well-known flexible MEC-based method with adjustable accuracy is considered for modeling. Hence shorter processing time and more flexibility compared to Finite-Element-Method (FEM) are needed. Finally, the effectiveness of the presented works is proved by the performed validation via both FEM and experimental results.
Full-Page Wrapper Generation for Unsupervised Deep Web Data Extraction
Authors: Chang Chia-Hui
Published: September 2021

Web data extraction is a key component in many business intelligence tasks, such as data transformation, exchange, and analysis. Many approaches have been proposed, with either labeled training examples (supervised) or annotation-free training pages (unsupervised). However, most research focuses on extraction effectiveness. Not much attention has been paid to extraction efficiency. In fact, most unsupervised web data extraction ignores wrapper generation because they could work alone without any supervision.

In this paper, we argue that wrapper generation for unsupervised web data extraction is as important as supervised wrapper induction because the generated wrappers could work more efficiently without sophisticated analysis during testing. We consider two approaches for wrapper generation: schema-guided finite-state machine (FSM) approaches and data-driven machine learning (ML) approaches. We exploit unique mandatory templates to improve the FSM-based wrapper, and proposed two convolutional neural network (CNN)-based models for sequence-labeling. The experimental results show that the FSM wrapper performs well even with small training data, while the CNN-based models require more training pages to achieve the same effectiveness but are more efficient with GPU support. Furthermore, FSM wrappers can work as a filter to reduce the number of training pages and advance the learning curve for wrapper generation.

Metabolome profiling of 106 plasma samples and 24 swab samples from symptomatic patients in the Indian population of the Mumbai region was done. COVID-19 positive samples were further segregated under the non-severe COVID-19 and severe COVID-19 patient cohort for both plasma and swab.Results. After analyzing the raw files, total 7,949 and 12,871 metabolites in plasma and swab were found. 11 and 35 significantly altered metabolites were found in COVID-19 positive compared to COVID-19 negative plasma and swab samples, respectively. Also, 9 and 23 significantly altered metabolites were found in severe COVID-19 positive to non-severe COVID-19 positive plasma and swab samples, respectively. The majorly affected pathways in COVID-19 patients were found to be the amino acid metabolism pathway, sphingosine metabolism pathway, and bile salt metabolism pathway.Conclusion. This study facilitates identification of potential metabolite-based biomarker candidates for rapid diagnosis and prognosis for clinical applications.

The aim of the study was to conduct a comparative assessment of the optical density of bone tissue of the alveolar process of the jaws of rats in supraocclusive relationships of individual teeth in the age aspect.
Materials and methods: The study was performed on 60 white laboratory rats. Rats were divided into control (30 individuals) and experimental (30 individuals) groups. According to the age of rats each group was divided into 3 subgroups (10 animals): young, mature and senile. In the experimental group, the state of supraocclusion was modeled by increasing the height of the lower right second molars placing a seal 1 mm high. Experimental animals were removed from the experiment on the 15th day through decapitation. The lower jaws were skeletonized, jaw blocks were sawn in the molar area. Bone mineral density was determined using optical densitometry. The statistical processing defined the average (M) and its error (m). The statistical significance of the difference in two independent groups was performed according to nonparametric criteria (Mann-Whitney U-test and W-Wilcoxon test). Statistical processing was conducted with the help of integrated package of statistical program AtteStat 12.0.5 for MS Excel. Differences at p≤ 0.05 were considered statistically significant.
Results: Statistical discrepancy is present in rats of mature and senile age, as well as between the indicators of all rats of the control and experimental groups (≤0.05). No significant difference was observed in young rats, but the indicators of the experimental group were 3.82% worse than in the control group. In senile rats, the density of the alveolar process decreased by 26.6%, in adult rats by 17.5%.
Conclusions: The presence of supraocclusive relationships of individual teeth causes a decrease in bone density of the alveolar process of the jaws in rats. The greatest loss of density among age groups in elderly rats.

The aim was to determine the role of obesity in the development of fatal complications and deaths in victims with abdominal trauma.
Materials and methods: The study was conducted on the basis of the Department of Polytrauma at the Municipal Health Care Institution of Kharkiv City Council ”O.I. Meshchaninov City Clinical Hospital of Ambulance and Emergency Care”. The authors have analyzed the case histories of 240 patients with abdominal trauma depending on the presence of obesity, which was determined by BMI (body mass index) and/or waist circumference (WC).
Results: Complications were found in 93 (38.8%) victims, 34 (14.2%) victims died. It was found that the overall incidence of complications, respiratory and hemocoagulation complications, the incidence of multiple organ failure (MOF) and mortality significantly increased in obese victims. Determination of obesity by the value of the BMI during hospitalization was possible in 41.7% of victims. The identification of WC turned out to be no less informative, but more accessible.
Conclusions: Obesity increases the incidence of complications and mortality in victims of abdominal trauma, and is a marker of a negative prognosis. Traditional assessment of BMI during hospitalization in most victims with abdominal trauma is not possible due to the severity of the condition and/or the presence of combined injuries. A good alternative to determining obesity in victims with abdominal trauma is a WC (more than 88 cm in women and more than 102 cm in men).

The aim: Study of hemodynamics of the prostate and evaluation of the effectiveness of extracorporeal shock wave therapy (ESWT) in the complex treatment of patients with chronic prostatitis with non-inflammatory chronic pelvic pain syndrome (NCPPS), (NIH III B).
Materials and methods: There were 63 patients with NCPPS aged 29 to 45 years, with a disease duration of more than 3 years and low efficacy of treatment against the background of standard therapy. All patients received standard therapy according to the clinical protocol. The main group (33 men – group II), against the background of standard therapy, received a course of ESWT, followed by a comparative assessment of clinical results regarding to the group of patients (30 men – group I) who received only standard therapy after the course, and after 3 and 6 months after treatment.
Results: According to the results of transrectal ultrasonography in Doppler mode, a marked decrease in volumetric blood flow in the prostate gland of patients was observed. The use of ESWT against the background of standard treatment contributed to a longer and more stable clinical effect, with a significant improvement in hemodynamic parameters in the prostate unlike the results in the group of patients receiving only standard therapy.
Conclusions: Significant disorders of prostate hemodynamics were found in patients with NCPPS. Use on the background of standard treatment of ESWT in these patients is pathogenetically justified with a lasting and stable clinical effect.

The aim: To identify admission variables associated with Functional Ambulation Classification (FAC) 1 to 4 (unable to walk without assistance) at time of discharge (dFAC<5) from a comprehensive stroke unit (CSU).
Materials and methods: Patients admitted to CSU at Oberig Clinic, Kyiv, Ukraine, August 01, 2012 to July 31, 2018, were screened for study selection criteria. Association of qualifying patients’ data with FAC score at CSU discharge was retrospectively assessed by univariate and multivariate logistic regression, odds ratios (OR) and 95% confidence intervals (95% CI) using MedCalc v. 19.1.
Results: The study cohort (442 of 492 admitted patients) had median age: 65.8 years, gender: 43% female, stroke-type: 84% ischemic strokes, median baseline NIHSS total score: 10. Estimated time from stroke onset to CSU admission was from less-than-24-hours to over-180-days. The univariate logistic regression analysis, revealed 28 variables significantly (p<0.05) related to dFAC<5; while in multivariate analysis only 4 admission variables were significantly (p<0.05) associated with dFAC<5: age (OR= 1.07; 95% CI 1.03-1.10, on average, for each additional year, p<0.001), baseline NIHSS score (OR= 1.15; 95% CI 1.08-1.22, on average, with a 1-point increase in the total score, p<0.001), initial FAC score (OR= 0.40; 95% CI 0.31–0.52, on average, with a 1-point decrease in the score, p<0.001), and very late CSU admission (over 180 days; OR= 5.7; 95% CI 1.9–17.1, p=0.002).
Conclusions: Four admission variables may be independently associated with dFAC<5 and provide opportunity for improving CSU outcomes and mitigating risk for inability to ambulate without assistance after CSU discharge.

The aim: To study the structural and functional state of bone tissue in men with ankylosing spondylitis and to asses its relationship with the course of the disease.
Materials and methods: the study was conducted involving 105 men, aged 40.74 ± 0.87 years and 25 generally healthy individuals of the certain age and sex, who formed the control group. The functional ability was assessed by the BASFI index and the disease activity was calculated by ASDAS-CRP and BASDAI. Laboratory criteria for the activity of the inflammatory process were considered erythrocyte sedimentation rate and C-reactive protein. Bone mineral density of the lumbar spine and femoral neck was determined by dual energy X-ray absorptiometry.
Results: osteoporosis and osteopenic syndrome were identified in men with ankylosing spondylitis in 27,7% and 29,5% consequently. Disorder of the structural and functional state of bone tissue was closely related to the total indicators of inflammatory activity in ASDAS-CRP (r = –0,36), BASDAI (r = –0,51), the functional index BASFI (r = –0,30), C-reactive protein (r = –0,30) and the cumulative dose of glucocorticoids (r = –0.32). The comparative analysis of densitometric parameters in groups of patients depending on the form of the disease has not shown statistically significant differences.
Conclusions: The decrease in bone mineral density in patients with ankylosing spondylitis does not depend on age and duration of the disease, but is associated with the cumulative dose of glucocorticoids and high activity of the inflammatory process.

The aim: To analyse human right issues in health care during the SARS CoV-2 pandemic from the perspective of patients’ and medical practitioner’s rights. Materials and methods: Multidisciplinary research will be conducted as part of national as well as international health care policy documents, international human right instruments, including case law decisions, and also major scientific articles on human rights from the healthcare perspective will be analysed. The comparative, Research synthesis method and systemic analyses will be made during the research. Results: The study confirmed that human right issues in the context of health care in case of Patient triage become relevant and transformed. The situation of COVID-19 has created new precedents for human rights, with a particular impact on the rights of doctors and patients. Conclusions: Human rights from the healthcare perspective become the topical issue during the COVID 19 pandemic. The legal practice in human rights had several transformations and it provides new challenges from patients as well as medical practitioners’ rights. Important problem, from the ethical -legal perspective is the Patient‘s triage. The situation on patients triage or ranking shows importance and possibility of each member state to act fast, taking into consideration fast changing situation in medical health system. Sorting patients whose lives are at risk according to certain criteria for assessing their lives is not acceptable. In order to reduce events of violations of human rights during COVID 19 in healthcare, the emphasis should be placed for explanation of decisions made in state level.
