El principal reto en los sistemas de educación superior en los dos últimos años, a raíz de la pandemia mundial de COVID-19, ha sido el poder mantener la calidad de la educación impartida con las restricciones de movilidad y aforos impuestas por las autoridades. Es por el ello que la transformación hacia actividades docentes no presenciales supone uno de los principales objetivos del sistema educativo. Con todo ello en mente, en este artículo se presenta una experiencia docente basada en la virtualización de procesos industriales y la aplicación de sistemas de control en el marco de prácticas de asignaturas de ingeniería de control en tiempo real. Para poder logarlo y además disponer de un sistema con gran realismo, se han integrado los softwares de virtualización de componentes “Factory I/O”, junto con softwares de control como “Matlab” a través de Node-RED, todo ello en tiempo real. Con esto, se consigue emular con gran realismo las plantas de control de nivel disponibles en los laboratorios de la Escuela Universitaria Politécnica de la Universidade da Coruña.

Published: November 2021

Neste traballo reflíctese unha experiencia de asistencia remota nunha asignatura base dunha enxeñería. Trátase da asignatura Resistencia dos Materiais, impartida no segundo cuatrimestre en distintos graos no ámbito da enxeñería industrial. A teoría, boletíns de exercícios e prácticas de laboratorio impartíronse en modalidade asíncrona mediante videos breves realizados con ScreenCastOMatic, usando como repositorio a páxina de Moodle da asignatura. Asociado a cada tema había un cuestionario Moodle para reforzar a teoría. Realizouse unha programación síncrona de casos prácticos con un foro de dúbidas asociado. A avaliación constaba de exame final, cuestionarios e práctica de laboratorio. Os exercicios do exame abríanse paulatinamente en Moodle e resolvíanse a man para ser posteriormente escaneados e enviados via correo electrónico. As tutorías, resolvéronse síncronamente por correo electrónico. As incidencias foron pouco significativas, debidas maioritariamente á entrega do exame fóra do prazo establecido. Os resultados, vistos coa perspectiva de anos anteriores, foron excelentes non só pola elevada taxa de éxito, senon tamén pola baixa taxa de non presentados.

A situación derivada da pandemia provocada pola COVID-19 transformou substancialmente as metodoloxías de ensino-aprendizaxe. Unha mudanza moi evidente deuse nos instrumentos de avaliación ao teren que se adaptar ás modalidades de ensino online e semipresencial. O grupo de innovación GIPED-INNOVA deseñou unha investigación có obxectivo de coñecer os instrumentos de avaliación que se empregaron durante o curso académico, o valor que lle dan os estudantes e como este varía en función da motivación académica destes. No estudo participaron 178 estudantes das materias que imparten os docentes de GIPED-INNOVA. Para a recollida da información, elaborouse un cuestionario online ad hoc no que se incluíron os distintos instrumentos que se poden empregar para avaliar o rendemento do alumnado na Universidade da Coruña. Por outra banda, para coñecer a motivación dos estudantes utilizouse o Cuestionario de Metas Académicas. Segundo os resultados, os participantes consideran que os docentes de GIPED-INNOVA empregan en maior medida instrumentos de avaliación relativos ás prácticas de aula. Ademais, os estudantes que adoptan metas de aprendizaxe valoran especialmente estas ferramentas xunto a asistencia a clase. Non obstante, nin os estudantes con metas de rendemento nin aqueles con metas de aprendizaxe valoran os instrumento tipo proba.

Published: November 2021

A mortalidade das Micro e Pequenas Empresas (MPEs) tem sido alvo de estudos no meio acadêmico, contudo, pouco se pode afirmar sobre a relação existente entre a contabilidade, a formação acadêmica do profissional, a consultoria e a sobrevivência das MPEs. Desta forma, o presente estudo objetivou avaliar a percepção dos contadores acerca da sustentabilidade em MPE e como a consultoria contábil poderia auxiliar estas empresas na manutenção de suas atividades. Foram realizadas 12 entrevistas semiestruturadas com profissionais representantes de escritórios contábeis e a análise dos dados captados nas entrevistas se deu por meio de técnicas de análise de conteúdo. Os resultados apontaram como as 6 principais causas dos altos índices de mortalidade enfrentados pelas MPEs, na visão dos entrevistados: burocracias relativas ao mercado; dificuldades financeiras enfrentadas pelas empresas; alta carga tributária; incapacidade de gestão do empreendedor; situação econômica do país; e mudança de ramo e/ou porte da entidade. Ainda, observou-se que estes índices podem ser amenizados por meio da prestação do serviço de consultoria contábil, principalmente no que tange ao planejamento prévio, antes da abertura da empresa.
Evaluation of Printing Parameters on 3D Extrusion Printing of Pluronic Hydrogels and Machine Learning Guided Parameter Recommendation
Authors: Fu Zhouquan , Angeline Vincent , Sun Wei
Published: November 2021

Bioprinting is an emerging technology for the construction of complex three-dimensional (3D) constructs used in various biomedical applications. One of the challenges in this field is the delicate manipulation of material properties and various disparate printing parameters to create structures with high fidelity. Understanding the effects of certain parameters and identifying optimal parameters for creating highly accurate structures are therefore a worthwhile subject to investigate. The objective of this study is to investigate high-impact print parameters on the printing printability and develop a preliminary machine learning model to optimize printing parameters. The results of this study will lead to an exploration of machine learning applications in bioprinting and to an improved understanding between 3D printing parameters and structural printability. Reported results include the effects of rheological property, nozzle gauge, nozzle temperature, path height, and ink composition on the printability of Pluronic F127. The developed Support Vector Machine model generated a process map to assist the selection of optimal printing parameters to yield high quality prints with high probability (>75%). Future work with more generalized machine learning models in bioprinting is also discussed in this article. The finding of this study provides a simple tool to improve printability of extrusion-based bioprinting with minimum experimentations.

Published: November 2021

Current research of designing prosthetic robotic hands mainly focuses on improving their functionality by devising new mechanical structures and actuation systems. Most of existing work relies on a single structure/system (e.g., bone-only or tissue-only) and ignores the fact that the human hand is composed of multiple functional structures (e.g., skin, bones, muscles, and tendons). This may increase the difficulty of the design process and lower the flexibility of the fabricated hand. To tackle this problem, this paper proposes a three-dimensional (3D) printable multi-layer design that models the hand with the layers of skin, tissues, and bones. The proposed design first obtains the 3D surface model of a target hand via 3D scanning, and then generates the 3D bone models from the surface model based on a fast template matching method. To overcome the disadvantage of the rigid bone layer in deformation, the tissue layer is introduced and represented by a concentric tubebased structure, of which the deformability can be explicitly controlled by a parameter. The experimental results show that the proposed design outperforms previous designs remarkably. With the proposed design, prosthetic robotic hands can be produced quickly with low cost and be customizable and deformable.
As Aproximações Teórico-Práticas entre a Gestalt-terapia e a Comunicação Não-Violenta
Authors: SPINDOLA, Jusedna; , MAES Karol , TESSARO Luiz Gustavo Santos
Published: November 2021

This article aims to investigate the theoretical-practical approaches of Gestalt-therapy (GT) and Nonviolent Communication (NC) in order to theoretically support possible psychological practices to use them simultaneously. The investigations started from the history of both and their respective founders. Through historical analysis, the influence of the Person-Centered Approach in the dialogues between GT and NC is perceived. Then, the investigations take place on an epistemological basis, addressing Phenomenology, existential assumptions and Humanistic Psychology. Finally, we discuss the main concepts and how they come together. Regarding the GT, the concept of Creative Adjustment and its forms of confluence, introjection, projection, retroflection and egotism are approached; and, regarding NC, the components of observation, feeling, need and request are addressed. Finally, the Grok game is cited as a practical approach. In view of such approaches, it is evident that the GT and the NC value the individual's potential and believe in his inseparability with the environment. From this point of view, both defend the importance of the human being's awareness of the feelings and needs that arise in and around him, in order to promote a more empathic and, therefore, less violent society.

To get an objective picture of the state of near-earth space, it is necessary to update the fleet of information tools in a timely manner, which is characterized by the introduction of new tools and the modernization of old tools, while changing the system in stages as the funds are ready. The continuous build-up of the system's assets as they are ready allows us to improve its performance without waiting for all newly introduced and upgraded assets to be ready. To test monitoring systems in conditions of a large number of heterogeneous elements combined in a system to achieve a single goal, an experimental and theoretical method of evaluating effectiveness based on mathematical modeling is used. The essence of this method is to simulate information at the input of programs of the system tools using mathematical models implemented directly on the system tools themselves. In this case, the quality of test trajectories that would allow evaluating the characteristics of radar information tools and the capabilities of monitoring systems is of particular importance. The purpose of the study is to increase the reliability of the results of tests of radar information tools for monitoring space debris by selecting a rational set of trajectory options that allow for the worst possible implementation of the capabilities of radar information tools, taking into account the functioning of each specific radar information tool participating in the tests. Based on the features of the factor space for finding solutions to the problem of forming test trajectories, the algorithm for forming the initial population and the algorithm for generating a new generation should be supplemented with blocks for checking the observability and feasibility of trajectories. The developed method of forming a rational set of variants of test trajectories using genetic algorithms differs from the known ones in that it generates a set of variants of test trajectories optimized from the point of view of obtaining the worst implementations of the capabilities of radar systems during its testing, under conditions of restrictions on the feasibility and observability of trajectories, the application of the methodology allows automating the process of preparing initial data for testing space debris monitoring systems in order to evaluate their characteristics. The application of the developed method allows to obtain the maximum errors in determining the parameters of the trajectory of space debris elements.
Low-frequency ultrasound bactericidal capacity study in intermittent ultrasonication process
Authors: Sabelnikov V.V. , Sabelnikova T.M. , Goryacheva V.N.
Published: November 2021

The low-frequency ultrasound (f = 26.5 kHz) was found to have a bactericidal effect upon the main representatives of bacterial flora: Staphylococcus, Proteus, E-coli and Pseudomanas aeruginosa. However, ultrasound suppresses bacterial flora during a comparatively long ultrasonication time ranging from 18 to 27 min. It was found that the determinant factor ensuring the bactericidal effect of low-frequency ultrasound is cavitation. To reduce the required ultrasonication time, while maintaining the high bactericidal effect, Bauman Moscow State Technical University (BMSTU) has developed a new ultrasonic treatment method designed for infected wounds and patented in the RF [8]. When implementing this method, it is proposed to intensify the cavitational effect of ultrasound through complementary physical and chemical factors: low-concentration antiseptic agents, excessive external static pressure, and optimum temperature of ultrasonicated solution. The proposed intensification of ultrasonic effect was found to reduce the sterilization time of bacterial suspensions from 5 to 7.2 times, while keeping the maximum required ultrasonication time within 5 min. The article considers further potential reduction of cavitational exposure time for tissues on the basis of earlier found aftereffect of ultrasound. This aftereffect means that a pre-sonicated solution has higher bactericidal properties than non-sonicated solutions and preserves its bactericidal capacity for specific time [11]. The article demonstrates the efficacy of the continuous ultrasonication process replacement by the intermittent process, which follows the cycle: ultrasonication – pause – ultrasonication. Experiments proved that, with optimum temporal relationship between the periods of ultrasonic exposure and rest, the complete sterilization end-time of bacterial suspensions can be reduced still more by 20…30%. Thus, the proposed intermittent ultrasonication process is an effective instrument of reducing the cavitational exposure of an organism, while maintaining its high bactericidal effect no worse than that of the continuous ultrasonication process. The research findings were successfully tested in the Traumatology department of N.N. Burdenko Main Military Clinical Hospital during the trial of the proposed method for ultrasonic treatment of infected wounds.
Investigation of the effect of doping the GaN buffer layer with carbon on the avalanche breakdown effect of normally open HEMT AlGaN/AlN/GaN transistors
Authors: Phyo Kyaw Than
Published: November 2021

The influence of the GaN buffer layer doped with carbon on the avalanche breakdown effect of normally open HEMT AlGaN / AlN / GaN transistors was studied. The avalanche breakdown was simulated in a structure where the gate length is LG = 0.3 mkm, the distance between the source and gate is LSG = 1.5 mkm, and the distance between the gate and drain is LGD = 2.2 mkm. For modeling, consider a layer doped with carbon, the thickness of which is 0.3 mkm, and the layer is located at a distance of 20 nm from the channel. The Simulation showed that with an increase in the concentration of carbon doping of the buffer, the breakdown voltage increases in the range UB = 225 – 360 (V). When the layer thickness changes to 0.4 mkm, the breakdown voltage increases in the range UB = 230 – 446 (V). For a structure where the gate length is LG = 0.8 mkm, the distance between the source and the gate is LSG = 1.0 mkm, the distance between the gate and drain is LGD = 3.0 mkm, the breakdown voltage increases in the range UB = 300 – 622 (V).

Published: November 2021

The paper deals with the dynamic process of local destruction of an object of armor protection. It is modeled as an object of destruction in the form of a spherical shell, and the threat is represented in the form of a metal round bar. Formulas are given and an estimate of the acceleration rate at which the object of armor protection is guaranteed to lose continuity is made. It is shown that if the rod has a tip covered with a layer of iridium, then under certain conditions, due to the fact that this metal has a high dynamic viscosity under intense loads, the object of armor protection is highly likely to be hit.

Published: November 2021

In this paper, we consider the problem of maintaining the energy balance of the power supply system of the Earth remote sensing spacecraft in critical operating conditions with the most intense cyclogram of the spacecraft operation, the maximum state of degradation of energy sources and storage devices, as well as with the minimum time to replenish useful energy.The problem of maintaining balance is formulated as a problem of nonlinear mathematical programming with functional constraints. Goal of the work is improving the efficiency and survivability of the remote sensing spacecraft and maintaining the energy balance of the power system in critical operating conditions by transferring the storage devices of the accumulating subsystem of the spacecraft to a given level of charge in the minimum charge time. An algorithm for controlling the accelerated charge of the rechargeable battery with the analysis of the Nickel-hydrogen battery temperature and its time derivative is developed.in some cases, the rechargeable battery replenishment time was reduced by 12−20%. The proposed algorithm for maintaining the energy balance can be used to select the stages of the accumulating subsystem charge current and transition from the current stage to the next one in a minimum time, providing flexibility in managing the modes of electricity storage with the adaptation of the charging current profiles to changing critical operating conditions.

Published: November 2021

The article deals with the issue of stealth of radio-electronic means, energy and structural, radio-electronic masking and ways of its implementation. The structure of the unknown signal for exploration and its parameters, as well as the a posteriori probability of each signal associated with the a priori likelihood function and the cases of its solution. The advantages and disadvantages of broadband signals and their characteristics used in modern radars are considered. On the basis of which conclusions are drawn: LFM radio pulse and a single FCM pulse, used in target tracking modes, has high resolution capabilities in range and radial velocity. The ACF of the FCM pulse has side lobes that raise the target detection threshold, as a result of which radar targets with a weak echo signal can be missed. The considered signals do not provide energy and structural stealth of the radar operation.

Published: November 2021

Third quarter of 2021 was marked by the appearance of technologically mature augmented reality (AR) equipment, which is positioned by the leaders of all leading IT companies as the next wave of radical changes in digital technology after the spread of smartphones. The process is accompanied by the beginning of the introduction of AR in education, applications of this kind are becoming widespread. Due to the comparative novelty and attractiveness for users, the educational practice of AR is ahead of the accompanying research activity. Despite the already existing large volume of publications on this topic, most of them are preliminary, dedicated to certain private aspects. A very problematic, although natural for a new technology, circumstance is the lack of publications on the consequences of long-term use of this tool in training. At the same time, there is no doubt that there is a significant potential for improving the efficiency of educational processes via AR, especially in university practice and when teaching students of radio engineering specialties. In the Russian Federation, there is a noticeable lag in the application of augmented reality technology in educational practice for students of specialties that are not directly related to software development. The purpose of this paper is to fill in this didactic gap in radio engineering education. The paper highlights the practice of using an augmented reality application for smartphones in the educational process for three months in 2021 at Moscow State Technical University of Civil Aviation. The specific capabilities of virtual and augmented reality technologies are correlated, the expediency of their use in education compared. The results of a long-term educational application of augmented reality are shown. The paper allows to identify promising problems of using augmented reality technology in radio engineering education from a research perspective, as well as to formulate didactic recommendations.

Published: November 2021

Problem formulating. The quasi one-dimensional conductor TaS3 of the orthorhombic modification shows strong electromechanical coupling of the sliding charge density wave (CDW) with the lattice of crystals. However, until now the effect of the dynamic deformation of the sample on the CDW sliding has not been studied. Goal. Search and study of a new effect: the influence of sample vibration on CDW dynamics. Result. The conductivity of TaS3 samples is studied as a function of the electric field and the frequency of mechanical deformation of the sample. It is found that when the vibration frequency of the piezoelectric actuators deforming the sample coincides with one of the mechanical resonances of the sample, suppression of the threshold field and features in the form of Shapiro steps are observed on the I–V characteristics. The effect is similar (though not equivalent) to that of RF voltage applied directly to the sample at the same frequency. Evidence is provided that these features are not coupled with the effect of electrical interference. Practical meaning. The result opens up a new area of electromechanical effects in quasi one-dimensional conductors with CDW and can be used for detecting and processing of mechanical oscillations in the microwave range.

Published: November 2021

Non-Communicable Diseases such as stroke, diabetes mellitus, heart attack, and hypertension have increasingly lurked in Indonesia. The excessive consumption of sugar, salt, and fat (SSF) is the trigger for that case, and the government tries to take precautions for people from 13 to 18 years of age. Emphasizing on preventive health communication efforts, this study intended to assist the health promotion program of Puskesmas Purwokerto Utara 2 to apply Public Relations functions by providing IEC (Communication, Information, and Education) on controlling SSF in adolescents. This research used in-depth interviews and observations as data collection techniques, with qualitative descriptive methods to analyze the data. The result showed that this Puskesmas (district clinic) is identified as not implementing the SSF Control Program since its health promotion function is still more focused on routine programs. Meanwhile, 1.021 students in this work area need to prevent threatening diseases. Making collaboration with competent partners, Puskesmas may apply the functions of Public Relations in implementing the preventive programs by providing sufficient information about the danger of the excessive consumption of SSF, inviting people to change attitudes and actions, and representing the organization’s attitude towards society.

Enhancing Peer Learning through Online Placements for Health and Social Care Professions
Authors: Taylor Lisa , Salmon Gilly
Published: November 2021

This article reports on the innovative design and the delivery of an online placement for university students, in response to the suspension of face-to-face placements due to COVID-19 restrictions in April 2020. A high quality, evidence-based and pedagogically sound experience was built, delivered and reviewed. The online placement not only met the professional standards and demonstrated equivalence in achieving placement learning outcomes, compared to traditional face to face placements, but also offered emergent benefits. The online placement showed enhanced peer learning and improved professional reasoning development by the students. In view of the interest and need for alternative placements, online placements were explored further, contextualised and built into a model which came to be known as Peer-Enhanced E-Placement (PEEP). Throughout 2020, and into 2021, the ‘logjam’ of increased student numbers and reduced placements, dramatically increased the interest in alternative placement learning and the PEEP model. A PEEP professional development acquisition experience was developed and piloted, to disseminate, scale and contextualize the approach by health and social care teams. Feedback from the pilot acquisition experiences indicated that the participants were able to design and implement PEEPs in their own contexts with their students. The scaling up and roll out of the PEEP acquisition experiences now extends to over fifteen professions. Conclusions include that the PEEP model offers a viable, acceptable and successful online practice-based learning option for health and social care students, achieving equivalence in placement learning outcomes and enhanced peer learning.
(Re)conceptualizing Difference in the Context of the Acting Subject’s Identity
Authors: Walczak Anna
Published: November 2021

What is the source and the effect of the acting subject’s identity? This question refers to difference, but not in its usual conceptualization, synonymous with a border and the need to maintain or transcend it. By reconceptualizing difference, which I see as “re-creating” the meaning and linking it with “added” meanings, this article restores its original load (importance) in being an acting subject, mediated in otherness. For this purpose, the différance of Jacques Derrida is invoked and his statements about it combined with those of other philosophers, in whom I found what is related and/or complementary and extends not only Derrida's thought, but that which constitutes the main theme of this article. On the one hand, otherness is an impulse to the “work” of the difference, and on the other hand, it is its effect. What is the role of the “work” of the difference in creating the identity of the acting subject? In connection with the “shift” of the effect of its work – otherness, into the area of the identity of the acting subject, can this subject say about itself: this is still me? In this context, what is responsive ethics, which, I believe, should be included in the contemporary humanistic and social discourse about the subject?
El impacto de políticas diferenciadas de cuarentena sobre la mortalidad por COVID-19: el caso de Brasil y Perú
Authors: Cozzubo Angelo , Herrera Javier , Razafindrakoto Mireile , Roubaud François
Published: November 2021

Según la Universidad Johns Hopkins, Brasil y el Perú se encuentran entre los cinco países con el mayor número de infectados en el mundo (octubre 2020) y donde la letalidad por COVID-19 ha sido de las más elevadas. Este estudio propone determinar el impacto del COVID-19 sobre la mortalidad, considerando las medidas de confinamiento, la pobreza y la movilidad residencial; ello contrastando Perú y Brasil como dos casos de políticas de emergencia contrarias. Para responder a la pregunta de investigación, el análisis emplea información de mortalidad de actualización diaria y desagregada a nivel municipal para ambos países. El análisis aplica un conjunto de medidas de relación y heterogeneidad espacial local y global entre los niveles de sobremortalidad subnacionales considerando datos armonizados. Complementariamente, se plantea un modelo de estudio de eventos de fallecimientos distritales para ambos países entre 2019-2020, y se miden impactos heterogéneos por edad, sexo, pobreza y movilidad residencial. El análisis espacial muestra que el patrón de muertes dista de ser aleatorio en el espacio; y que los hotspots de sobremortalidad comienzan en las “grandes ciudades” y se diseminan en el tiempo. Del mismo modo, el estudio de eventos muestra que el efecto no es lineal, sino que hay una evolución de corto y largo plazo de las muertes donde los grupos más afectados resultan ser los hombres y adultos mayores. Finalmente, considerando el caso de Lima, es posible verificar que la movilidad tiene un efecto significativo y positivo en la sobremortalidad, particularmente en distritos pobres, lo cual se condice con el final de la cuarentena.

The study sample consisted of (214) EFL teachers at Irbid Governorate selected using random sampling method. To achieve the study objectives, a questionnaire consisted of (36) items was distributed on the study sample. The study showed that knowledge level of language assessment among Jordanian EFL teachers was low. The study revealed statistically significant differences in the knowledge level of language assessment among Jordanian EFL teachers due to years of experience, in favor of more than 10 years and due to qualification, in favor of PhD, while there were no statistically significant differences in light of gender. In light of the results the study suggests to pay more attention by university administrations to design training programs able to fulfill the actual needs of EFL pre-service teachers in Jordan.

IMAGINARNI PRIJATELJI KAO PRODUKT DEČJEG STVARALAŠTVA
Authors: Bogdanović Ana , Klemenović Jasmina
Published: November 2021

Stvaralaštvo predstavlja najslobodniji oblik samoizražavanja. Sposobnost stvaralaštva i stvaranje nečega iz ličnih osećanja pozitivno se odražava na dečje emocionalno zdravlje. Ono je opšteljudski potencijal čije je ispoljavanje i razvijanje važno podržati. Sloboda sadržana u stvaralaštvu omogućava detetu da upozna sebe, da deluje unutar svoje ličnosti, da se suoči, da razume i da se odupre svojim različitim unutrašnjim porivima. Stvaralački čin proističe iz unutrašnjih želja i potreba deteta i predstavlja odraz njegove mašte i imaginacije. Jednim od njenih ishoda može se smatrati i pojava imaginarnog prijatelja. Predškolci vole da stvaraju razne situacije i isprobavaju različite uloge u igri, te nije neobično da stvore imaginarnog prijatelja. Imaginarni prijatelj je nevidljiv lik kojeg dete imenuje i govori o njemu i sa njim, u periodu od najmanje nekoliko meseci. On omogućava detetu da istražuje stvari, materijale, prerađuje iskustva na jedan sasvim novi način, kao i da stvara imaginarne svetove. Ovim putem dete slobodnije istražuje svet oko sebe, oslanjajući se na svoju kreativnost i maštu.

Authors: Pacheco Katiucy Besen Pedroso
Published: November 2021

O sistema eleitoral sofreu diversas modificações através dos tempos, o que gerou alterações na legislação e novas soluções para problemáticas envolvendo a arrecadação e os gastos de campanha. Com este artigo busca-se apresentar a legislação envolvendo o tema, bem como discorrer sobre o tipo de financiamento de campanha adotado no Brasil, com as respectivas alterações legislativas. Tendo ainda por fito, identificar as dificuldades decorrentes da análise das prestações de contas, inclusive no que tange os recursos humanos envolvidos no processo de análise, bem como os efeitos da sentença de julgamento dos processos de prestação de contas. Utilizando-se como metodologia de pesquisas bibliográficas e normativas e método teórico bibliográfico, dividiu-se o presente artigo em três partes, sendo primeiramente abordada a evolução do financiamento de campanha, tendo-se como pergunta a ser problematizada: A Justiça Eleitoral é capaz de cumprir sua função Constitucional de fiscalizar a arrecadação e os gastos de campanha eleitoral? Desta forma, identificaremos as formas de fiscalização exercidas através das inovações tecnológicas e a efetividade da prestação jurisdicional dada à sociedade.
NOTAS PARA UM MODELO DE RACIONALIDADE LEGISLATIVA EM MATÉRIA PENAL
Authors: Johner Marcos Afonso
Published: November 2021

Este artigo objetiva verificar como tornar mais racional o processo legislativo em matéria penal, de modo a responder ao seguinte problema: quais os parâmetros adequados para racionalizar o processo legislativo em matéria penal? O texto seguirá o método de abordagem hipotético-dedutivo, mediante pesquisa bibliográfica, reunindo livros jurídicos e artigos acadêmicos relacionados ao tema estudado. Ao final constatar-se-á que um processo legislativo que se pretenda racional deve ser guiado por três níveis distintos: um relativo à fase pré-legislativa, contendo as causas do problema; outro, correspondente ao processo legislativo propriamente dito, reunindo os critérios de elaboração da lei; e, por fim, um relacionado à fase pós-legislativa, que avalie se a lei cumpriu os objetivos aos quais se propunha.
A VALORAÇÃO DA PALAVRA DA VÍTIMA NOS CRIMES CONTRA A DIGNIDADE SEXUAL COMO PRINCIPAL MEIO DE PROVA
Authors: Ortiz Denize Dos Santos , Amaral Priscilla Honorato do
Published: November 2021

No Brasil não há, em tese, hierarquia entre as provas no processo penal, como regra, as provas produzidas em um processo, possuem o mesmo valor probatório, porém, excepcionalmente, nos crimes cometidos contra a dignidade sexual, que, na maioria das vezes, são consumados na clandestinidade, há grande dificuldade em sua comprovação, o que permite que a palavra da vítima ganhe relevância para o deslinde processual. Entretanto, existem problemas no que tange a valoração da palavra da vítima, quais sejam, as falsas memórias, a mentira, pois existem casos em que a vítima, ao ser rejeitada pelo parceiro, imputa a ele um crime que jamais cometeu, movimentando todo Poder Judiciário a fim de alcançar uma condenação daquele acusado, como forma de punição pela rejeição. Seria justo valorar a palavra da vítima? Ao fazer a valoração não se estaria ferindo o princípio do in dubio pro reo? Portanto, a palavra da vítima só possui um valor probatório maior nesse tipo de delito se estiver em conformidade com as demais provas dos autos, para evitar o cometimento de injustiças.

Published: November 2021

O presente artigo objetivou correlacionar Justiça Animal e pandemias zoonóticas, mais especialmente, a COVID-19. A metodologia versada fora uma Pesquisa teórica. A dominação e a opressão a que submetemos os animais não humanos, concretizados nos inimagináveis maus-tratos, não somente os fere e mata, mas também repercute negativamente em nossas vidas e no meio ambiente sob a noção de One Health. A COVID-19 expõe outra vez o perigo letal do desrespeito ao Bem-estar Animal. A urgente conscientização da sociedade sobre a importância da Defesa Animal traduz-se como imprescindível na tentativa de reduzir os riscos de novas pandemias.

Bacteria need a medium that can play an important role in their growth. One example of a medium is the medium De Mann Rogosa and Sharpe (MRS) which is a specific medium for the growth of lactic acid bacteria. The use of MRS media on an industrial scale is ineffective due to its relatively high price. The purpose of this study was to find out the effect of skim milk media enriched with green coconut water and cornstarch on the growth of Lactobacillus casei bacteria. The type of research conducted is experimental research with post test only control group design where there are two groups, namely the control group and the experimental group. The experimental group consisted of 3 types of samples, namely skim milk and green coconut water, skim milk and cornstarch, as well as skim milk and green coconut water and cornstarch. The comparison of treatment levels for each sample was 1:2 and 1:3 and analyzed, including bacterial growth curves, growth speed and bacterial generation time. From each concentration, the results found that the addition of green coconut water and cornstarch had a significant effect on the growth of Lactobacillus casei (P˂0.01) to the speed of growth and generation time. It was concluded that the higher the concentration added it can accelerate the growth of Lactobacillus casei.
