Authors: Barulin A. E. , Klauchek S. V. , Klauchek A. E.
Published: December 2021

Purpose of the study. To establish the relationship between neurophysiological status and the level of efficiency in young people with bruxism.

Materials and methods. Two groups of 64 and 53 subjects (males and females) aged 20–35 years old with bruxism and non-bruxers were formed according to questionnaire results and physical examination. The level of efficiency was assessed by the results of sensorimotor tracking of a moving object (the ‘Smile’ model). Spectral analysis was performed for evaluation of the baseline electroencephalograms. Microsoft Excel and Statistica 10.0 programs were used for statistical data processing.

Results. The level of efficiency was statistically significantly lower in the hardest test of Smile model among the individuals with bruxism (p < 0.05). The bruxers also demonstrated a significantly lower dominant frequency and maximum amplitude of alpha-rhythm (p < 0.05), and significantly higher dominant frequency of beta2 rhythm (p < 0.05). The dominant frequency and the maximum amplitude of the alpha-rhythm are parameters corresponding to significant coefficients of the regression analysis. A negative relationship was found between the degree of error during sensorimotor tracking and the frequency and amplitude of alpha-rhythm.

Conclusion. Regression models present the relationship between the level of efficiency and the alpha-rhythm severity. The regression equations make it possible to determine the functional state of the subject using an electroencephalogram.

Published: December 2021

Dysfunction of the pelvic organs in tumor lesions of the spinal cord is up to 20%. Registration of the bulbocavernosus reflex is performed to assess the integrity of the segmental apparatus of the spinal cord. Polymodal neurophysiological monitoring includes registration of the bulbocavernosus reflex during surgery of spinal cord tumors. The effect of the components of general anesthesia on the parameters of the bulbocavernosus reflex varies significantly according to various medical sources. The aim of the work was to compare the effect of inhalation anesthesia (sevoflurane) and total intravenous anesthesia (propofol) on the parameters of the bulbocavernosus reflex in the surgical treatment of spinal cord tumors. Thirty patients with intradural extramedullary and intramedullary tumors of the spinal cord at the level of Th11–S2 vertebrae were included in the study. The amplitude-frequency parameters of the bulbocavernosus reflex and the threshold intensity of stimulation were assessed in the study. The results of the study demonstrate that intraoperative registration of the bulbocavernosus reflex during resection of tumors of the distal spinal cord can be performed both with inhalation and total intravenous anesthesia. A sustained motor response of the bulbocavernosus reflex requires a higher intensity of stimulation with inhalation anesthesia with sevoflurane than with total intravenous anesthesia. If during the operation the depth of propofol's anesthesia increases by 1 mg/kg/h, then it is necessary to increase the current strength during stimulation by 10–11 mA.

Based on the example of seasonal epidemics of respiratory viral infections, it is partially possible to model the outcomes of neurological complications from Covid‑19, taking into account the pathogenetic features of the virus effect on the vascular wall and nerve cells. The accumulated experience of doctors of various specialties makes it possible to prevent such life-threatening complications as ACVA, PATE, intoxication, and sepsis. From the first days of the disease, it is necessary to conduct dynamic monitoring of blood rheology, the level of systemic oxygenation, use anticoagulants in preventive doses in patients at the early stages of the disease, conduct therapy aimed at reducing the risk of cytokine storm development.

Authors: Korotysh M. A. , Svetozarskiy S. N. , Kopishinskaia S. V.
Published: December 2021

Sarcopenia is a progressive generalized muscle disorder, associated with an increased risk of falls, fractures, physical disability, and mortality. Sarcopenia criteria are based on an assessment of a triad of symptoms – a decrease in muscle mass, muscle strength, and impaired physical performance. The most common diagnostic methods are handgrip dynamometry, densitometry, bioimpedansometry, and gait speed measurement. These methods have high accuracy and prognostic value, but are not always applicable to neurological patients. The article discusses sarcopenia detection in neurological practice, as well as its connection with neurodegenerative disorders – Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis. Having a number of common pathophysiological mechanisms, each of the diseases is characterized by a specific phenotype of muscle atrophy. The high incidence of sarcopenia symptoms in neurodegenerative diseases and the common mechanisms of their development allow us to treat sarcopenia as an overlap syndrome of neurodegenerative disorders.

The relevance of the article is connected with the emergence of such a scientific category in law as «digitalization». Digitalization processes are being actively introduced into public, political, economic and legal life directly by authorities, for example, the Government of the Russian Federation, which by 2021 is moving from «electronic Government» to «Digital Government», introducing digital technologies into the system of executive authorities as digitalization tools for fast and effective digital interaction both among themselves and to optimize interaction with citizens and organizations. This issue requires a scientific analysis. Therefore, the main purpose of the article will be to study the problems, scientific research of the current state and prospects of mutual influence of digitalization and digital space in the law of the modern Russian state, analysis of the role of digitalization in law as a legal category. The article also analyzes the legal concepts of digitalization, it is noted that the Concept of Government will be transformed into a Digital Government in 2021. The implementation of this transformation is carried out by the Government of the Russian Federation itself, the Ministry of Digital Development of the Russian Federation on behalf of the President of the Russian Federation. At the same time, this concept does not aim to replace the traditional system of state authorities or transform bodies, but is aimed at increasing the accessibility and quality of interaction between the population of the state and the authorities, as well as digital interaction between the state and municipal authorities themselves. It is noted that there is a tendency to transform public power into the mainstream of digital technologies and digital interaction, for this purpose a number of legal documents have been created - concepts, in particular, the concept of the digital economy, implemented on behalf of the President of the Russian Federation.
WILLIAM JETHRO BROWN'S CRITIQUE OF JOHN AUSTIN'S LEGAL THEORY AS A STAGE IN THE DEVELOPMENT OF LEGAL POSITIVISM
Authors:   Moscow State Institute of International Relations (University) MFA Russia, Moscow, Russia, KORZHENYAK ANASTASIA , MIKHAILOV ANTON
Published: December 2021

The purpose of the research. This article analyses the main points of the legal teaching of the Australian jurist William Jethro Brown (1868-1930), which the authors of this study regard as forming one of the significant stages in the evolution of Anglo-American legal positivism. Along with his contemporaries, a New Zealand lawyer John William Salmond (1862-1924) and British jurists Thomas Erskine Holland (1835-1926) and John Mason Lightwood (1852-1947), Brown was among the first critics of the «command theory of law» of the founder of the analytical school of jurisprudence John Austin (1790-1859). The authors of this article prove that the ideas, including those of W. Brown, play the role of a link between the founders of the analytical school of law (J. Bentham, J. Austin), the teachings of William Markby, Sheldon Amos, and subsequent generations of English legal scholars of both positivist and neo-positivist direction. Many provisions of Brown's legal doctrine became the basis for criticism of Austin's command concept and legal understanding in the teachings of H. L. A. Hart, the central figure of English neopositivism of the 20th century. As a result of the research the authors conclude that there are comparative similarities between W. J. Brown's conception of «rules of external action», J. W. Salmond's idea of «ultimate legal principles» and H. L. A. Hart's legal doctrine on the «rule of recognition».
FOR A DISCUSSION ABOUT THE “MUNICIPAL FILTER”
Authors:   Lipetsk State Pedagogical P. Semenov-Tyan-Shansky University, Lipetsk, Russia, MARKOV ROMAN
Published: December 2021

The model for elections of top officials of the constituent entities of the Russian Federation, which was restored by amendments to the federal legislation in 2012, differs significantly from the previous regional election campaigns and establishes special conditions for the participation of candidates. These include support for the nomination of a candidate for the post of head of a constituent entity of the Russian Federation by representatives of local authorities elected by the population - municipal deputies and heads of municipal formations, which very quickly received the informal name “municipal filter” among lawyers, political scientists and publicists. Among other novelties of electoral legislation, it is this requirement that has been the subject of sharp criticism for ten years. Materials and methods. In preparing the article, the authors analyzed federal legislation, by-laws, election campaign materials, and judicial practice of the Constitutional Court of the Russian Federation. The main methods used are technical-legal, formal-legal, comparative-legal. Results. The requirement to support the nomination of a candidate for the post of the highest official of a constituent entity of the Russian Federation can be assessed as a complex and contradictory procedure. It performs important functions in controlling the electoral process, ensuring the unity of the Russian public power system, developing local self-government, and strengthening the political and party systems. However, in modern Russian political conditions, the prevalence of a certain political force in local self-government bodies, the “municipal filter” is being transformed from a legal procedure into an instrument of unfair political struggle. Conclusions. The study substantiates the need to preserve and reform the “municipal filter” in terms of reducing the minimum and maximum levels of support for candidates and reducing the territorial coverage of municipalities in the region.
ADMINISTRATIVE REGULATIONS OF STATE FUNCTIONS AT THE PRESENT STAGE: DYNAMICS OF CHANGES IN THE APPROACH TO THE CONCEPT AND VARIETIES AT THE LEGAL REGULATORY
Authors:   Tambov State University named after G.R.Derzhavin, Tambov, Russia, ZELEPUKIN ROMAN
Published: December 2021

In this article the author analyses the development of administrative regulations in the system of modern public administration. The state of administrative regulations and their institutionalisation as a result of the administrative reform is noted. It has been identified and found that there has now been a change in the approach to the delineation of the administrative regulations of the executive authorities - before 2018, administrative regulations were divided into service regulations and function regulations, where service regulations are related to requests by private persons to the state represented by its bodies and officials - and function regulations are related to the implementation of continuous activities to perform assigned powers and exercise the established competence, after 2018, administrative regulations are divided into service regulations and control (supervision) regulations. According to the author, the established approach has allowed the above varieties of regulations to be merged into such a group of types of administrative regulations as administrative regulations for the implementation of state functions. Also the author concludes that it is necessary to adopt a special legislative act systemising the functions of the executive authorities and the administrative procedures they carry out in a single logical connection.

Authors:   Peoples` Friendship University of Russia (RUDN University), BELIKOVA KSENIA
Published: December 2021

Based on the legal material of the BRICS countries the article touches upon the issue of legal responsibility of a scientist, creator, operator, etc. for the implementation of the results of his scientific activities in the field of new military technologies. Interest is caused by the impact on legal and military science, as well as on the ideas of both ordinary people and specialists (lawyers, military, sociologists, etc.) provided by new technologies that currently allow to do things that previously could not even be imagined otherwise than in imaginative literature, films, etc. In this way, the current provisions of normative acts (in the field of legislation on intellectual property), ethical codes, etc., and doctrines (works of specialists who give arguments "pro" and "contra" giving legal personality to artificial intelligence) are examined. Scientific novelty is due, firstly, to the choice of countries - these are the BRICS countries, secondly, the subject of the study is the legal responsibility for the implementation of the results of scientific activity of a scientist in the field of new military technologies, thirdly, the analysis of a selected range of issues in an interdisciplinary aspect - from the standpoint of jurisprudence, military science, ethics. Among the conclusions reached by the author, the inevitability of ethical problems when using AI in civil (for example, transport) and military autonomous systems. In this regard, attempts have been made to solve these problems in the BRICS countries in various ways: from declarative limitations in patent legislation to the development of guidelines and ethical principles that meet the realities. The need to develop a single document with an international legal status on the issue of AI-human interaction, based on the opinions and ideas about the principles of such interaction of more than eighty subjects from around the world is also showed.

Published: December 2021

In addition to the devastating effects of anxiety and stress on the development and exacerbation of the cardiovascular disease, lack of stress control increases drivers' risk of accidents. This paper aims to identify the stress of drivers in various driving situations to warn the driver to control the tense conditions during driving. In order to detect stress while driving, we used the heart signals in the Physionet database. To analyze the conditions of the electrocardiogram (ECG) under various driving situations, linear and non-linear features were used. The characteristics of the RRIs are the only able to identify driver stress in different driving modes relative to rest periods, while the return mapping features, in addition to identifying driver stress while resting, have the ability to identify stress between different driving positions also brought. The results showed that driver's stress level during driving in city 1 and highway 1 with a P-value of 0.028 and also in city 3 and highway 2 with a P-value of 0.041 can be distinguished. The accuracy obtained from the proposed detection method is 98±2% for 100 iterations. The result indicated an efficiency of our proposed method and enhanced the reliability.
Ensemble based on Accuracy and Diversity Weighting for Evolving Data Streams
Authors: Sun Yange , Shao Han , Zhang Bencai
Published: December 2021

Ensemble classification is an actively researched paradigm that has received much attention due to increasing real-world applications. The crucial issue of ensemble learning is to construct a pool of base classifiers with accuracy and diversity. In this paper, unlike conventional data-streams oriented ensemble methods, we propose a novel Measure via both Accuracy and Diversity (MAD) instead of one of them to supervise ensemble learning. Based on MAD, a novel online ensemble method called Accuracy and Diversity weighted Ensemble (ADE) effectively handles concept drift in data streams. ADE mainly uses the following three steps to construct a concept-drift oriented ensemble: for the current data window, 1) a new base classifier is constructed based on the current concept when drift detect, 2) MAD is used to measure the performance of ensemble members, and 3) a newly built classifier replaces the worst base classifier. If the newly constructed classifier is the worst one, the replacement has not occurred. Comparing with the state-of-art algorithms, ADE exceeds the current best-related algorithm by 2.38% in average classification accuracy. Experimental results show that the proposed method can effectively adapt to different types of drifts.

Published: December 2021

Global Software Development (GSD) involves multiple sites which comprise of different cultures and time zones apart from geographical locations. It is a common software development approach adopted to achieve competitiveness. However, due to multiple challenges it can result in misunderstandings and rework. Rework raises the chance of project failure by delaying the project and increasing the estimated budget. The aim of this study is to identify and categorize the rework causes to reduce its frequency in GSD. To identify the empirical literature related to causes of rework, we performed a Systematic Literature Review (SLR). A total of 23 studies are included as a result of final inclusion. The empirical literature from the year 2009 to 2020 is searched. The overall identified causes of rework in GSD are categorized into 6 major categories which are communication, Requirement Management (RM), roles of stakeholders, product development/integration issues, documentation issues, and differences among stakeholders. The most reported rework causes are related to the category of communication & coordination and RM. Moreover, an industrial survey is conducted to validate the identified rework causes and their mitigation practices from practitioners. This study will help practitioners and researchers in addressing the identified causes and therefore reduce the chances of rework.

Published: December 2021

In the ubiquitously connected world of IT infrastructure, Intrusion Detection System (IDS) plays vital role. IDS is considered as a critical component of security infrastructure and is implemented either through hardware or software devices and can detect malicious activities in a networked environment. To detect or prevent network attacks, Network Intrusion Detection (NID) system may be equipped with machine learning algorithms to achieve better accuracy and faster detection speed. Analyzing different attacks effectively through Dimensionality Reduction Algorithms is an efficient mechanism. The significance of these algorithms is they improvise feature selection from huge datasets. Also through this the learning speed is enhanced. Speed is a crucial parameter in the success of network intrusion detection systems for defending reactions. In this paper open source datasets Knowledge Discovery in Databases (KDD CUP) dataset and 10% KDD CUP dataset are employed for experimentation. These datasets are provided to Dimensionality Reduction Algorithms like Principal Component Analysis (PCA), Linear Discriminate Analysis (LDA) and Kernel PCA with different kernels and classified with Logistic Regression classification algorithm for procuring accurate results. Further to boost up the accuracy achieved so far K-fold algorithm is utilized. Finally a comparative study of different accuracy results is done by using K-fold algorithm and also without the usage of this algorithm. The empirical study on KDD CUP data confirms the effectiveness of the proposed scheme. In this paper we discovered the combination of multiple dimensionality reduction algorithm such as PCA , LDA and Kernel PCA with classification algorithm and this combination of algorithm gives best result. Our study will help out the researchers to uncover critical area such as intrusion detection in network traffic environment. The results what we identified will be very much helpful for researchers for their future research on KDD CUP dataset. In this the new theory will be arrived by this research that the best accuracy achieved by PCA with 10% KDD CUP dataset experimental results without KFold attained 98% and with KFold attained 99%. LDA with 10% KDD CUP Dataset experimental results without KFold attained 98% and with KFold attained 99%.

Authors: Majrashi Khalid
Published: December 2021

Voice User Interfaces (VUIs) are increasingly popular owing to improvements in automatic speech recognition. However, the understanding of user interaction with VUIs, particularly Arabic VUIs, remains limited. Hence, this research compared user performance, learnability, and satisfaction when using voice and keyboard-and-mouse input modalities for text creation on Arabic user interfaces. A Voice-enabled Email Interface (VEI) and a Traditional Email Interface (TEI) were developed. Forty participants attempted pre-prepared and self-generated message creation tasks using voice on the VEI, and the keyboard-and-mouse modal on the TEI. The results showed that participants were faster (by 1.76 to 2.67 minutes) in pre-prepared message creation using voice than using the keyboard and mouse. Participants were also faster (by 1.72 to 2.49 minutes) in self-generated message creation using voice than using the keyboard and mouse. Although the learning curves were more efficient with the VEI, more participants were satisfied with the TEI. With the VEI, participants reported problems, such as misrecognitions and misspellings, but were satisfied about the visibility of possible executable commands and about the overall accuracy of voice recognition.

Authors: Chinnaiah Valliyammai , Kiliroor Cinu C
Published: December 2021

Spam is an undesirable content that present on online social networking sites, while spammers are the users who post this content on social networking sites. Unwanted messages posted on Twitter may have several goals and the spam tweets can interfere with statistics presented by Twitter mining tools and squander users’ attention.. Since Twitter has achieved a lot of attractiveness through-out the world, the interest towards it by the spammers and malevolent users is also increases. To overcome the spam problems many researchers proposed ideas using machine learning algorithms for the identification of spam messages. Not only the selection of classifiers but also the variegated feature analysis is essential for the identification of irrelevant messages in social networks. The proposed model performs a heterogeneous feature analysis on the twitter data streams for classifying the unsolicited messages using binary and continuous feature extraction with sentiment analysis on social network datasets. The features created are assessed using significant stratagems and the finest features are selected. A classifier model is built using these feature vectors to predict and identify the spam messages in Twitter. The experimental results clearly show that the proposed Sentiment Analysis based Binary and Continuous Feature Extraction model with Random Forest (SA-BC-RF) approach classifies the spam messages from the social networks with an accuracy of 90.72% when compared with the other state-of-the-art methods.
Energy Heterogeneity Analysis of Heterogeneous Clustering Protocols
Authors: Hassan Shahzad , Ahmad Maria
Published: December 2021

In Wireless Sensor Networks the nodes have restricted battery power and the exhaustion of battery depends on various issues. In recent developments, various clustering protocols have been proposed to diminish the energy depletion of the node and prolong the network lifespan by reducing power consumption. However, each protocol is inappropriate for heterogeneous wireless sensor networks. The efficiency of heterogeneous wireless sensor networks declines as changing the node heterogeneity. This paper reviews cluster head selection criteria of various clustering protocols for heterogeneous wireless sensor networks in terms of node heterogeneity and compares the performance of these protocols on several parameters like clustering technique, cluster head selection criteria, nodes lifetime, energy efficiency under two-level and three-level heterogeneous wireless sensor networks protocols Stable Election Protocol (SEP), Zonal-Stable Election Protocol (ZSEP), Distributed Energy-Efficient Clustering (DEEC), A Direct Transmission And Residual Energy Based Stable Election Protocol (DTRE-SEP), Developed Distributed Energy-Efficient Clustering (DDEEC), Zone-Based Heterogeneous Clustering Protocol (ZBHCP), Enhanced Distributed Energy Efficient Clustering (EDEEC), Threshold Distributed Energy Efficient Clustering (TDEEC), Enhanced Stable Election Protocol (SEP-E), and Threshold Stable Election Protocol (TSEP). The comparison has shown that the TDEEC has very effective results over other over two-level and three-level heterogeneous wireless sensor networks protocols and has extended the unstable region significantly. From simulations, it can also be proved that adding node heterogeneity can significantly increase the network life.
User-Centric Adaptive Password Policies to Combat Password Fatigue
Authors: Al-Slais Yaqoob , El-Medany Wael
Published: December 2021

Today, online users will have an average of 25 password-protected accounts online, yet use, on average, 6.5 passwords. The excessive cognitive burden of remembering large amounts of passwords causes Password Fatigue. Therefore users tend to reuse passwords or recycle password patterns whenever prompted to change their passwords regularly. Researchers have created Adaptive Password Policies to prevent users from creating new passwords similar to previously created ones. However, this approach creates user frustration as it neglects users’ cognitive burden. This paper proposes a novel User-Centric Adaptive Password Policy (UCAPP) Framework for password creation and management that assigns users system-generated passwords based on a cognitive-behavioural agent-based model. The framework comprises a Password Policy Assignment Test (PassPAST), a Cognitive Burden Scale (CBS), a User Profiling Algorithm, and a Password Generator (PassGEN). The framework creates tailor-made password policies that maintain password memorability for users of different cognitive thresholds without sacrificing password strength and entropy. The framework successfully created 30-40% stronger passwords for Critical users and random (non-mnemonic) passwords for Typical users based on each individual’s cognitive password thresholds in a preliminary test.
The Delay Measurement and Analysis of Unreachable Hosts of Internet
Authors: Gezer Ali
Published: December 2021

Delay related metrics are significant quality of service criteria for the performance evaluation of networks. Almost all delay related measurement and analysis studies take into consideration the reachable sources of Internet. However, unreachable sources might also shed light upon some problems such as worm propagation. In this study, we carry out a delay measurement study of unreachable destinations and analyse the delay dynamics of unreachable nodes. 2. Internet Control Message Protocol (ICMP) destination unreachable Internet Control Message Protocol-Destination Unreachable (ICMP T3) packets are considered for the delay measurement according to their code types which shows network un reach ability, host un reach ability, port un reach ability, etc. Measurement results show that unreachable sources exhibit totally different delay behaviour compared to reachable IP hosts. A significant part of the unreachable hosts experiences extra 3 seconds Round Trip Time (RTT) delay compared to accessible hosts mostly due to host un reach ability. It is also seen that, approximately 79% of destination un reach ability causes from host un reach ability. Obtained Hurst parameter estimation results reveal that unreachable host RTTs show lower Hurst degree compared to reachable hosts which is approximately a random behaviour. Unreachable sources exhibit totally different distributional characteristic compared to accessible ones which is best fitted with Phased Bi-Exponential distribution.
GPS Receiver Position Augmentation Using Correntropy Kalman Filter in Low Latitude Terrain
Authors: Pagoti Sirish Kumar , Vemuri Bala Sai Srilatha Indira Dutt , Laveti Ganesh
Published: December 2021

If any Global Positioning System (GPS) receiver is operated in low latitude regions or urban canyons, the visibility further reduces. These system constraints lead to many challenges in providing precise GPS position accuracy over the Indian subcontinent. As a result, the standalone GPS accuracy does not meet the aircraft landing requirements, such as Category I (CAT-I) Precision Approaches. However, the required accuracy can be achieved by augmenting the GPS. Among all these issues, the predominant factors that significantly influence the receiver position accuracy are selecting a user/receiver position estimation algorithm. In this article, a novel method is proposed based on correntropy and designated as Correntropy Kalman Filter (CKF) for precise GPS applications and GPS Aided Geosynchronous equatorial orbit Augmented Navigation (GAGAN) based aircraft landings over the low latitude Indian subcontinent. The real-world GPS data collected from a dual-frequency GPS receiver located in the southern region of the Indian subcontinent (IISc), Bangalore with Lat/Long: 13.021°N/ 77.5°E) is used for the performance evaluation of the proposed algorithm. Results prove that the proposed CKF algorithm exhibits significant improvement (up to 34%) in position estimation compared to the traditional Kalman Filter.
Evaluation of Regeneration and Apoptosis in Experimental Hepatic Resection of Rats
Authors: ÖZTÜRK Şamil , İRKİN Latife Ceyda
Published: December 2021

Objective: Apoptosis and accompanying regeneration begins immediately after liver resection and transpalantation. It is known that DNA synthesis reaches its maximum level in the first 24-48 hours after resection. This study was carried out to examine the regeneration and apoptotic process in the liver of rats that underwent 70% liver resection on days 3 and 7.

Materials and Methods: 21 adult male Wistar Albino rats were used. The laparotomy with an upper midline incision was performed on the subjects for liver resection. Three groups were formed as the control (Group I), the group that was sacrificed 3 days after resection (Group II), and the group that was sacrificed 7 days after resection (Group III).

Results: Sinusoidal dilatation and vacuolization in hepatocytes were observed in the liver tissues of all experimental groups except the control group. However, these histopathological findings were observed more in group II than other groups. It was observed that the apoptotic index and proliferation index values reached the maximum level in the group II. In group III, it was observed that these index values gradually decreased. Values of these parameters were found to be quite low in control group.

Conclusion: As a result, comparisons of the mechanisms accompanying the regeneration occurring after resection were determined by immunohistochemical and TUNEL methods, and findings that shed light on clinical applications were obtained day by day.

Published: December 2021

Este texto cartografa encontros de um grupo de estudos e pesquisas em uma universidade pública. Leituras e abertura de mundos, gerando possibilidades de-formativas entre educadoras/pesquisadoras. Cartografia (ROLNIK, 2007; DELEUZE; GUATTARI, 1995) que, variando entre imprevistos, desimportâncias e aspectos comumente desconsiderados nos processos formativos, convoca outros movimentos de atenção e presença. E, também, experimentações com a escrita, que se alinhava em multiplicidade, ativando vozes e derivações. Encontros pensados como acontecimentos que produzem efeitos e convidam a desaprender (BARTHES, 1989). Deslocamentos em direção ao desconhecido. Desaprendizagens entre anotações de cadernos, conversas de corredor, danças, telas de computador, espantos, perplexidades e vizinhanças. Vivendo a educação como criação de circunstâncias (DELIGNY, 2018). Corpo coletivo produzido na ressonância dos encontros. Ao longo do tempo, os espaços se alteram, passando pela mudança de campus da universidade e posteriores efeitos pandêmicos contagiando o tecer da narrativa.
Literaturas indígenas, educação e sonho
Authors: Wunder Alik
Published: December 2021

Como as palavras e imagens dos diferentes povos poderiam intensificar nossas micropolíticas inventivas na educação? Procuro pensar com as micropolíticas indígenas dos processos de criação literária, como “gérmens de mundos” (ROLNIK, 2019, p.26), como nos convida Suely Rolnik. Este texto se faz impulsionado pelo desejo de encontrar palavras que germinem mundos, desejo de que nossos movimentos na educação e na pesquisa em educação sejam de resistência a qualquer intenção de dominação dos corpos, de desprezo à vida, vidas humanas e não-humanas e de aniquilação da diferença. Busco pensar as potencialidades das histórias dos povos indígenas, desdobradas em literaturas, para trazer à educação uma conversa sobre o sonho. A literatura indígena contemporânea como um modo de encontrar e aprender com os sonhos ancestrais de diversos povos. Sonhos que sustentam as diversas estratégias de existência na floresta e de resistência destes povos às violências secularmente disparadas sobre eles. Sonhos que fazem parte da educação dos escritores e escritoras indígenas e que compõem seus modos de ver, criar e inventar novas histórias.

Os trânsitos para a cultura impressa. Marín, Avellaneda e a escritura pública no século XIX hispano-americano
Authors: Correa Chiarotti Guadalupe
Published: December 2021

Ao longo do século XIX, as mulheres travaram lutas tenazes em várias frentes. Talvez uma das mais sutis –mas também uma das mais implacáveis– tenha sido o campo da cultura e, mais especificamente, aquela parte que corresponde à literatura. Se se encontravam com mil objeções na leitura feminina, se até a escrita privada trazia perigos de todos os tipos; quantos riscos as mulheres não encontraram na publicação e na consequente exposição pública? Nas páginas que se seguem, vamos nos deter em alguns trechos editoriais em que são ensaiadas estratégias argumentativo-editoriais capazes de converter os preconceitos masculinos em condições de possibilidade para aceder ao mundo das letras.
O uso de fantoches e suas contribuições para a narrativa de crianças
Authors: Araujo Marcela A Moreira , Rocha Maria Silvia Pinto de Moura Librandi da
Published: December 2021

Resumo. Este artigo aborda parte dos resultados de pesquisa desenvolvida em uma turma de Educação Infantil de uma escola privada, visando estudar a possível contribuição do uso de fantoches para a construção de narrativas por crianças. Desenvolvida em 2017 a pesquisa compôs-se por conjunto de procedimentos metodológicos, dos quais destacamos dez encontros com a professora e a turma estudada. As análises do material empírico permitiram evidenciar que os fantoches, além de aumentarem a motivação das crianças para recontarem as histórias, afetaram, positivamente, a estrutura das narrativas: as crianças usam-nos para sustentar os enredos; criam e incluem mais personagens; experimentam diferentes vozes; constroem diálogos entre personagens e/ou atribuem características psicológicas a eles. Com este estudo, pretende-se contribuir para reflexões sobre a importância da construção de práticas pedagógicas diferenciadas relacionadas à literatura infantil e seus efeitos sobre o desenvolvimento das crianças.
Hierarchical Hydrogels with Ordered Micro-Nano Structures for Cancer-on-a-Chip Construction

Published: December 2021

In the drug therapy of tumor, efficient and stable drug screening platforms are required since the drug efficacy varies individually. Here, inspired by the microstructures of hepatic lobules, in which hepatocytes obtain nutrients from both capillary vessel and the central vein, we present a novel hierarchical hydrogel system with ordered micro-nano structure for liver cancer-on-a-chip construction and drug screening. The hierarchical hydrogel system was fabricated by using pregel to fill and replicate self-assembled colloidal crystal arrays and microcolumn array template. Due to the synergistic effect of its interconnected micro-nano structures, the resultant system could not only precisely control the size of cell spheroids but also realize adequate nutrient supply of cell spheroids. We have demonstrated that by integrating the hierarchical hydrogel system into a multichannel concentration gradients microfluidic chip, a functional liver cancer-on-a-chip could be constructed for high-throughput drug screening with good repeatability and high accuracy. These results indicated that the hierarchical hydrogel system and its derived liver cancer-on-a-chip are ideal platforms for drug screening and have great application potential in the field of personalized medicine.

X-ray imaging is a low-cost, powerful technology that has been extensively used in medical diagnosis and industrial nondestructive inspection. The ability of X-rays to penetrate through the body presents great advances for noninvasive imaging of its internal structure. In particular, the technological importance of X-ray imaging has led to the rapid development of high-performance X-ray detectors and the associated imaging applications. Here, we present an overview of the recent development of X-ray imaging-related technologies since the discovery of X-rays in the 1890s and discuss the fundamental mechanism of diverse X-ray imaging instruments, as well as their advantages and disadvantages on X-ray imaging performance. We also highlight various applications of advanced X-ray imaging in a diversity of fields. We further discuss future research directions and challenges in developing advanced next-generation materials that are crucial to the fabrication of flexible, low-dose, high-resolution X-ray imaging detectors.
“For know, alas, I’m dumb, alas I love": Rhetoric of disability, female agency and tragedy in ‘The Dumb Virgin’
Authors: Torralbo Caballero Juan de Dios
Published: December 2021

This essay will focus on the two sisters of “The Dumb Virgin; or, The Force of Imagination,” addressing the crossover between disability studies, feminism and aesthetic theory. It will examine how art has the capacity to manipulate nature and how nature may be improved by the intervention of human industry. With this aesthetic duality, it will suggest that the writer reframes the concept of the ‘normal’ body, establishing a rhetoric of deformity and disability through the characters of Belvideera and Maria, both of whom overcome their natural disabilities by means of personal effort. Lastly, it will investigate the ‘misfortunes’ of several characters, paying particular attention to the educated nature of the two protagonists and how this poses a threat to the established order of society. The conclusion to be drawn from this is that their challenge to the social construct is directly responsible for the tragic climax of the narrative.
