Detecção de botnets baseada na análise de fluxos de rede utilizando estatística inversa
Authors: Lopes Daniele A. G. , Marotta Marcelo A. , Ladeira Marcelo , Gondim João J. C.
Published: August 2022

Botnet é uma rede de computadores infectados, os quais são controlados remotamente por um cibercriminoso, denominado botmaster e que tem como objetivo realizar ataques cibernéticos massivos, como DDoS, SPAM e roubo de informações. Os métodos tradicionais de detecção de botnets, normalmente baseados em assinatura, são incapazes de detectar botnets desconhecidas. A análise baseada em comportamento tem sido promissora para a detecção de tendências atuais de botnets, as quais estão em constante evolução. Este artigo propõe um mecanismo de detecção de botnet baseado na análise do comportamento de fluxo de rede. A técnica utilizada para detecção de botnets foi recentemente desenvolvida e é denominada Energy-based Flow Classifier (EFC). Essa técnica utiliza estatística inversa para detecção de anomalias. Dois conjuntos de dados heterogêneos, CTU-13 e ISOT HTTP foram utilizados para avaliar a eficiência do modelo gerado e os resultados foram comparados com diversos classificadores tradicionais, de uma e de duas classes. Os resultados obtidos mostram que o EFC obteve resultados mais estáveis, independente do domínio, ao contrário dos demais algoritmos testados.

Published: August 2022

Este artigo apresenta o protocolo CodeTSCH, que utiliza a Codificação em Rede (Network Coding) em redes TSCH (Time-Slotted Channel Hoping) para otimizar a entrega de mensagens e diminuir o número de slots utilizados. Esse processo possibilita que duas mensagens sejam combinadas em apenas um pacote, possibilitando uma menor quantidade de mensagens circulando na rede, bem como uma maior robustez à perda de mensagens. Comparou-se o CodeTSCH em simulações com o protocolo estado da arte TSCH. Os resultados demonstram que o CodeTSCH permite uma entrega das mensagens com melhoria de até 50% em comparação com o protocolo estado da arte TSCH em redes com perdas de pacotes.

Published: August 2022

As redes ópticas metropolitanas (MON) estão passando por grandes transformações para continuar a oferecer serviços que atendam aos requisitos das aplicações do futuro. O tráfego dessas aplicações apresenta um comportamento diferente em cada horário do dia e em cada área específica da rede. As soluções agnósticas desse contexto não consideram tal distribuição desigual de tráfego. Este trabalho apresenta uma solução de roteamento e alocação de espectro ciente da área no contexto de redes ópticas metropolitanas elásticas (MEON). Tal proposta alcança o dobro de redução do bloqueio de largura de banda na rede como um todo, e pelo menos 1% de redução nas áreas compreensivas (CA) e residenciais (RA) existentes na metro.

Authors: M. e Silva Gabriel Lucas F. , Neira Anderson Bergamini de , Nogueira Michele
Published: August 2022

Dentre as ameaças existentes no ciberespaço, o ataque de negação de serviço distribuído (DDoS) destaca-se por interromper serviços essenciais, negando o acesso a usuários legítimos e causando prejuízos econômicos. A literatura apresenta mecanismos para defender as vítimas. Contudo, os ataques DDoS nem sempre são detectados a tempo para que os mecanismos de defesa evitem os prejuízos. Para aumentar o tempo que a defesa terá para reagir ao ataque, este trabalho propõe um sistema baseado no aprendizado profundo supervisionado para identificar sinais da orquestração de ataques DDoS. Transformando o tráfego de rede em sinais precoces de alerta, este trabalho treinou uma rede neural profunda para identificar anomalias e predizer os ataques DDoS. O sistema proposto foi avaliado no conjunto de dados CTU-13 que contém o tráfego de dois ataques de DDoS. O modelo predisse o lançamento do ataque com 46 minutos de antecedência e uma baixa quantidade de erros.

Background: The time of urination control varies in chHildren with environmental, genetic, geographical, and other factors. Objectives: We examined factors affecting urination control in children. Methods: We enrolled children aged over five years at Amirkabir hospital and Imam Reza pediatric clinic, Arak, Iran. They were divided into two groups with and without urinary incontinence. Demographic, epidemiological, clinical, and urinary factors in children were gathered in questionnaires. Data were analyzed in the SPSS program by chi-square and t-test. Results: The mean age was 6.45 ± 1.96 years. There were 436 (44.2%) males and 550 (55.8%) females. Anatomic and functional bladder disorders, UTIs, and organic disorders were the most common genetic factors, and toilet training neglect was the least common etiologic factor. Factors such as gender, living area, father, and mother education significantly differed between the two groups (P < 0.05). Conclusions: Proper and timely urination regarding personal, familial, and environmental factors plays a vital role in urination control in children.

Published: August 2022

Background: Restrictive measures caused by the COVID-19 have exposed the families' structure to some critical issues such as reduced quality of life and increased domestic violence. For this reason, the study of psychological factors are essential in this regard. Objectives: The study aimed to predict the quality of life and violence against women during COVID-19 quarantine based on resilience and coping styles. Methods: This descriptive correlation study was conducted on all married women in Karaj from October 1 to November 30, 2020. A total of 241 people were randomly selected as the sample and answered the questionnaires about coping styles, quality of life, violence against women, and resilience scale. The data were analysized by Pearson correlation test and regression analysis. Results: There was a significant positive relationship between resilience, efficient coping style, and quality of life, as well as a significant negative relationship between inefficient coping style and quality of life (P < 0.01). A significant negative relationship was observed between coping style with domestic violence, as well as a significant positive relationship between dysfunctional coping style and domestic violence (P < 0.01). Resilience and effective coping style predicted the quality of life, domestic violence, and ineffective coping style of domestic violence against women (P < 0.01). Conclusions: According to the results, individual and psychological factors of people could play a significant role in the occurrence of violence and thus reduce their quality of life. In educational-therapeutic sessions, counselors and family therapists increased the quality of life and reduced violence by examining coping styles and resilience to use educational strategies in this area.

The maturation of librarianship as a profession and science in Serbia after World War II
Authors: Grujić Dragana
Published: August 2022

The aim of the paper is to present the development of librarianship in Serbia in the period after the Second World War until today, in the period when there is a sudden professionalization and when librarianship through institutionalized education grows into a recognized social and humanities science. Based on the hitherto insufficiently known and little used archival material, the development of professional and competent staff in Serbia is highlighted as a precondition for the development of library science. It was noticed that in the period under review, librarianship developed rapidly. Special merits for that initially belong to the Serbian Library Association, and then to the Department for Librarianship and Information Science at the Faculty of Philology, University of Belgrade. The paper combines both historical and current efforts to improve librarianship and to keep up with the sciences of postmodern society.

Differentiated thyroid carcinomas is associated with an excellent prognosis. The treatment of choice for differentiated thyroid carcinoma is surgery, followed by radioactive iodine ablation (iodine-131) in select patients and thyroxine therapy in most patients. Surgery is also the main treatment for medullary thyroid carcinoma, and kinase inhibitors may be appropriate for select patients with recurrent or persistent disease that is not resectable. Anaplastic thyroid carcinoma is almost uniformly lethal, and iodine-131 imaging and radioactive iodine cannot be used. When systemic therapy is indicated, targeted therapy options are preferred. This article describes NCCN recommendations regarding management of medullary thyroid carcinoma and anaplastic thyroid carcinoma, and surgical management of differentiated thyroid carcinoma (papillary, follicular, Hürthle cell carcinoma).

Background:Polypharmacy and potentially inappropriate medications (PIMs) are common among older adults with blood cancers, but their association with frailty and how to manage them optimally remain unclear.Patients and Methods:From 2015 to 2019, patients aged ≥75 years presenting for initial oncology consult underwent screening geriatric assessment. Patients were determined to be robust, prefrail, or frail via deficit accumulation and phenotypic approaches. We quantified each patient’s total number of medications and PIMs using the Anticholinergic Risk Scale (ARS) and a scale we generated using the NCCN Medications of Concern called theGeriatric Oncology Potentially Inappropriate Medications(GO-PIM) scale. We assessed cross-sectional associations of PIMs with frailty in multivariable regression models adjusting for age, gender, and comorbidity.Results:Of 785 patients assessed, 603 (77%) were taking ≥5 medications and 421 (54%) were taking ≥8 medications; 201 (25%) were taking at least 1 PIM based on the ARS and 343 (44%) at least 1 PIM based on the GO-PIM scale. Among the 468 (60%) patients on active cancer treatment, taking ≥8 medications was associated with frailty (adjusted odds ratio [aOR], 2.82; 95% CI, 1.92–4.17). With each additional medication, the odds of being prefrail or frail increased 8% (aOR, 1.08; 95% CI, 1.04–1.12). With each 1-point increase on the ARS, the odds of being prefrail or frail increased 19% (aOR, 1.19; 95% CI, 1.03–1.39); with each additional PIM based on the GO-PIM scale, the odds increased 65% (aOR, 1.65; 95% CI, 1.34–2.04).Conclusions:Polypharmacy and PIMs are prevalent among older patients with blood cancers; taking ≥8 medications is strongly associated with frailty. These data suggest careful medication reconciliation for this population may be helpful, and deprescribing when possible is high-yield, especially for PIMs on the GO-PIM scale.
EUROPEAN QUALITY OF LIFE IN RETIREMENT - Analyzing Personal Differences based on SHARE data
Authors: Vaskoevi Agnes , Kovacs Erzsebet , Szanyi-Nagy Sara
Published: August 2022

Background Population ageing is one of the greatest challenges of the 21 century. While in 1996 the number of retirees to the total population in the European Union was 14.97%, by 2020 this number had risen to 20.6%. Numerous studies talk about different aspects of ageing, however the European economic and demographic literature do not pay enough attention to the quality of pensioners’ life. Objective In this paper, we provide a wide picture of their life exploring the individual differences. We used data from the 2017 wave of the multidisciplinary database Survey of Health, Aging and Retirement in Europe (SHARE), including personal data on 17,726 retired people from 24 European countries by demographics, education, health status, and their finances. Method We examined the differences with Principal component analysis and OneWay ANOVA evaluating the F-test significances. Results We found that (i) the health status of European pensioners depends mainly on their age and gender, (ii) investment habits are most significantly connected to education level and the region, (iii) happiness is particularly defined also by education and the region.
Regional Models of Corporate Sector Development in Russia: Where Does Family-Friendly Policy Matter Most? (A Study based on Cluster Analysis)
Authors: Bagirova Anna , Shubat Oksana
Published: August 2022

Despite being popular across the world, the concept of family-friendly policy is not associated with business in Russia. Our research focuses on the corporate sector and its potential to change the demographic context in Russia. The aim of the study is to identify regional models of the Russian corporate sector development and suggest pilot regions to start family-friendly policies aimed at increasing the birth rate. We used variables which characterise the corporate sector development in Russian regions and applied the hierarchical cluster analysis. Regional values of the indicators for all 85 Russian regions were analysed. We revealed 5 clusters and then additionally profiled the clusters selected according to the Total Fertility Rate. The analysis allowed us to identify two clusters of Russian regions which may become pilot ones when promoting family-friendly policy practices in their enterprises. We argue that a family-friendly policy in these clusters’ enterprises might become: relevant for employees; quite affordable for enterprises; a new effective tool of the demographic policy since the birth rates here are the lowest in Russia.

Taking randomness for granted: the complexities of applying random number streams in simulation modelling
Authors: Selmair Maximilian
Published: August 2022

Uncertainty, as a constant companion of our world, is one major reason why simulation modelling takes precedence over static calculations to achieve accurate predictions. Computational random number generators are able to algorithmically determine values on the basis of random distributions, which utilise seed values to calculate streams of random numbers. This deterministic approach to replicating seemingly non-deterministic numbers ensures stochastic models to be reproducible at any time – one of the major requirements of simulation models. However, there are some pitfalls in the application of random number streams in modelling and simulation, which may even mislead experienced developers. In addition to a general introduction of the history of random number generators, this article shares empirical considerations and means by which the utilisation of random number streams can be improved to deliver valid and reliable results.

Predicting Performance of Heterogeneous AI Systems with Discrete-Event Simulations
Authors: Zhdanovskiy Vyacheslav , Teplyakov Lev , Grigoryev Anton
Published: August 2022

In recent years, artificial intelligence (AI) technologies have found industrial applications in various fields. AI systems typically possess complex software and heterogeneous CPU/GPU hardware architecture, making it difficult to answer basic questions considering performance evaluation and software optimization. Where is the bottleneck impeding the system? How does the performance scale with the workload? How the speed-up of a specific module would contribute to the whole system? Finding the answers to these questions through experiments on the real system could require a lot of computational, human, financial, and time resources. A solution to cut these costs is to use a fast and accurate simulation model preparatory to implementing anything in the real system. In this paper, we propose a discrete-event simulation model of a high-load heterogeneous AI system in the context of video analytics. Using the proposed model, we estimate: 1) the performance scalability with the increasing number of cameras; 2) the performance impact of integrating a new module; 3) the performance gain from optimizing a single module. We show that the performance estimation accuracy of the proposed model is higher than 90%. We also demonstrate, that the considered system possesses a counter-intuitive relationship between workload and performance, which nevertheless is correctly inferred by the proposed simulation model.
Agent and Evolutionary-based Modelling and Simulation of a Simplified Living System
Authors: Sosnicki Adrian , Grzonka Daniel , Gaza Lukasz
Published: August 2022

Modelling artificial life has been an issue explored for several decades. However, science continues to surprise us with novel approaches to this problem. The aim of this paper is to innovative model a simplified living environment based on the agent paradigm and genetic algorithms. This paper also proposes a novel way of defining agent systems and artificial life embedded in a genetic approach. In the modelled and implemented environment there is one species of fauna and a simple species of flora that serves as food for the fauna. The fauna is implemented using agents inscribed in a genetic representation. The experimental part of the work includes calls to the simulator and the study of the dependencies resulting from the simulation mechanisms.
The Dutch East India Company (VOC) Tasman Map and Australia: Competing Interests, Myth Making, and an Australian Icon
Authors: Stevens Leonie , Russell Lynette
Published: August 2022

The floor of the entrance to the Mitchell Library vestibule, which is part of the State Library of New South Wales, displays a stunning mosaic 1939-1941 reproduction of a seventeenth century map recording Abel Tasman’s two journeys of 1642 and 1644. It charts the west, north and southern coasts of the Australian continent, but is incomplete, thus representing the historical moment between an imagined Terra Australis Incognita, and the final survey of the east coast which presaged British colonisation. The original Tasman map, also held by the Mitchell library and currently undergoing restoration, has a strange and chequered biography. This paper explores the myths associated with what is known colloquially as the Bonaparte Tasman map, in honour of its last owner Prince Roland Bonaparte, a nephew of Napoleon. We examine its contested origins and role as an agent of Dutch East India Company imperial ambitions, relegation to forgotten cast-off when that empire collapsed, Bonaparte’s desire to gift it to the nascent Australian Commonwealth as a symbol of new nationhood, and the international subterfuge involved in its acquisition by not by the nation, but the State Library of NSW. Analysis of what was known of the map in the decades prior to its arrival in Australia challenges the conventional narratives, and we propose the biography of the Tasman map (and its embodiment in the Mitchell Library vestibule mosaic) is a study in imperialism, colonialism, federation, and power.
On the question of the valence of emotive verbs in the Russian dialects of the Amur region
Authors: Fang Haixu , Sadchenko Valentina Tarasovna
Published: August 2022

The subject of the study is the valence characteristic of a group of verbs in the Russian dialects of the Amur region, characterized by secondary formation and localization in the territory of late settlement. Russian Russian dialects The relevance and novelty of this work lies in the fact that the specificity of verbal valence in Russian dialects remains poorly understood; for the first time an attempt has been made to study the valence properties of one of the lexico-semantic groups of dialect verbs, which are recorded in the second edition of the "Dictionary of Russian Dialects of the Amur region". Using the methods of continuous sampling, descriptive-analytical and comparative analysis, the classification of the studied linguistic units was developed and the valence properties of emotive verbs were revealed.   In the course of the study, 62 verbs with the meaning of an emotional state were identified, of which 31 verbs are actually lexical dialectisms. The material allowed us to distribute the selected emotive verbs into 3 lexico-semantic groups: monovalent, divalent and trivalent. The observations have shown that the valence properties of a dialect verb are due to the component composition of its lexical meaning and may differ from their literary counterparts. Russian Russian dialects of the Amur region can contribute to the construction of a general characteristic of the valency properties of the morphological class of verbs, as well as to the identification of differences in the combinational possibilities of the verbs of the Russian language in the aspect of its regional existence.
On edge irregularity strength of line graph and line cut-vertex graph of comb graph
Authors:   Department of Science & Humanities, PES University, Nagesh H. M. , Girish V. R. ,   Department of Science & Humanities, PES University
Published: August 2022

For a simple graph $G$, a vertex labeling $\phi:V(G) \rightarrow \{1, 2,\ldots,k\}$ is called $k$-labeling. The weight of an edge $xy$ in $G$, written $w_{\phi}(xy)$, is the sum of the labels of end vertices $x$ and $y$, i.e., $w_{\phi}(xy)=\phi(x)+\phi(y)$. A vertex $k$-labeling is defined to be an edge irregular $k$-labeling of the graph $G$ if for every two different edges $e$ and $f$, $w_{\phi}(e) \neq w_{\phi}(f)$. The minimum $k$ for which the graph $G$ has an edge irregular $k$-labeling is called the edge irregularity strength of $G$, written $es(G)$. In this paper, we find the exact value of edge irregularity strength of line graph of comb graph $P_n \bigodot K_1$ for $n=2,3,4$; and determine the bounds for $n \geq 5$. Also, the edge irregularity strength of line cut-vertex graph of $P_n \bigodot K_1$ for $n=2$; and determine the bounds for $n \geq 3$.

Evaluation of colonization and mutualistic endophytic symbiosis of Escherichia coli with tomato and Bermuda grass seedlings
Authors: Verma Satish K. , Chen Qiang , White James Francis
Published: August 2022

Escherichia coli is generally considered a bacterium associated with animal microbiomes. However, we present evidence that E. coli may also mutualistically colonize roots of plant species, even to the extent that it may become endophytic in plants. In this study we used GFP tagged E. coli to observe its colonization and effects on tomato (Solanum lycopersicum) and Bermuda grass (Cynodon dactylon) seedling development and growth. Inoculation with the bacterium significantly improved root development of both seedlings tested. Treatment also increased the photosynthetic pigments in Bermuda grass seedlings. However, effects on shoot length in both seedlings were not significant. This bacterium was found to produce indole acetic acid (IAA) up to 8.68 ± 0.43 µg ml−1 in the broth medium amended with tryptophan. Effects on seedling root growth could, in part, be explained by IAA production. Bacteria successfully colonized the root surfaces and interiors of both seedlings. Tagged bacteria expressing the GFP were observed in the vascular tissues of Bermuda grass seedling roots. Seedlings with bacteria showed greater survival and were healthier than seedlings without bacteria, indicating that E. coli set up a successful mutualistic symbiosis with seedlings. E. coli is not commonly considered to be a plant endophyte but is more generally considered to be a crop contaminant. In this study we show that E. coli may also be an endophyte in plant tissues.
Fused Cervical Vertebrae: A Case Series
Authors: Saminathan Suganya , Govindarajan Amudha
Published: August 2022

Vertebral fusion is the fusion of bodies and the various elements of the vertebral arch of adjacent vertebrae. Such vertebral fusion usually is seen in cervical and lumbar region, more so between the second and third cervical vertebrae, usually asymptomatic; but may also result in features suggestive of neurological compression and might also present difficulty in procedures like endotracheal intubation. This present case series involving three cases discusses the presentations and possible consequences of such vertebral fusions. The three Fused Cervical Vertebrae (FCV) studied were all different with respect to the degree and site of fusion. With respect to fusion of vertebral bodies, complete fusion was seen in two specimens and the other had only partial fusion. This series aimed at documenting the varied spectrum of vertebral fusions and the need for earlier detection so as to avoid the anticipated age related complications like degeneration of adjacent segments and neurological deficits. The observations made in this series and the comparative analysis with other articles show that the mode of vertebral fusions are very different in each specimen and thus their clinical presentations might also vary across numerous signs and symptoms for each individual and hence cannot be generalised.
A NATURALIZAÇÃO DA EXCLUSÃO/INCLUSÃO SOB O OLHAR DE UMA PESSOA CEGA: UMA DESCONSTRUÇÃO URGENTE E NECESSÁRIA
Authors: Leal Daniela
Published: August 2022

Ao longo da história, as pessoas cegas foram vistas e pensadas das mais diversas formas. No entanto, não é porque as concepções a respeito das mesmas transformaram-se, assim como as oportunidades de inclusão ampliaram-se com o passar do tempo, que essas deixaram de enfrentar condições estruturais que as oprimem e negligenciam. Pelo contrário, ainda hoje, as pessoas cegas são significadas de forma extremamente negativa e segregatória. Diante desse cenário, ao tentar compreender a história de Wagner, ex-aluno e ex-professor da Escola para Cegos “Helen Keller” de Ribeirão Preto (1950-1970), por meio de uma pesquisa de caráter historiográfico em triangulação com a pesquisa documental e a história oral, buscou-se apresentar como o fenômeno da exclusão/inclusão tornou-se naturalizado na constituição de Wagner enquanto aluno e professor cego.

Australia’s 2019–20 mega-fires burnt 79% of the Greater Blue Mountains World Heritage Area, prompting an urgent need for rapid on-ground post-fire assessments of flora and fauna to aid in post-fire recovery. This project aimed to determine spatial patterns in populations and assemblages of vertebrates, vertebrate temporal activity, and the diet of the invasive Red Fox Vulpes vulpes, across burnt and unburnt sites. Using remote camera traps we surveyed 12 unburnt and 10 burnt sites approximately 12 months after the fires. We detected 41 species (11 mammals, 28 birds and 2 reptiles), with different species composition, but similar vertebrate species richness across both unburnt and burnt sites. The relative abundance of the Eastern Grey Kangaroo Macropus giganteus, Common Wombat Vombatus ursinus and Australian Magpie Gymnorhina tibicen was higher in burnt sites, while small mammals (< 500 g) had higher relative abundance at unburnt sites. There was no difference in the relative abundance of the Superb Lyrebird Menura novaehollandiae across burnt and unburnt sites, and although 11 species of bird were only detected at unburnt sites, the numbers were too low for reliable estimates of differences. Red Fox scat analysis (n=23) revealed that invertebrates and plant material were the dominant prey items in both burnt and unburnt sites, but medium-sized mammals increased in Red Fox diets in burnt sites, and reptiles were consumed disproportionately more by Red Foxes in burnt compared to unburnt sites. Although the short-term nature of this study and low scat sample size limited detailed insights, our rapid survey was an effective tool to gain preliminary data on species responses to the 2019–20 megafires in the Blue Mountains and contribute to a baseline for understanding species recovery.

Nriman adalah proses di mana manusia menerima sebuah keadaan yang ada tanpa berani berargumen untuk melawan dan membantah. Keadaan nriman itu sendiri merupakan warisan tradisi adat ketimuran yang sudah mendarah daging. Proses nriman sendiri menggiring manusia mengikuti arus, tanpa ada pegangan. Sama halnya dengan benda cair yang selalu mengikuti bentuk sesuai wadahnya. Proses nriman dicoba diangkat oleh penulis dengan memvisualisasikan-nya sebagai seni ekspresi visual dengan teknik fotografi makro. Dengan memanfaatkan sifat benda cair, penulis mengombinasikan beberapa medium untuk menghasilkan sebuah tampilan visual menarik dan penuh makna, untuk merepresentasikan proses nriman tersebut.
GUAYRÁ
Authors: Soares Isabelle
Published: August 2022

Marco Aurélio Cremasco, autor de Guayrá (2017) é paranaense natural de Guaraci-PR. A maioria de suas obras literárias são livros de poesias. Como ficcionista, além de Guayrá, destaca-se a obra Santo Reis da Luz Divina (2007) cujo enredo trata da Guerra do Paraguai, um período histórico marcante e bastante lembrado na América Latina. Já a história do Guayrá e das missões jesuíticas no território que hoje é grande parte do Paraná caiu no esquecimento popular. Nesse sentido, o romance Guayrá se torna um “lugar de memória”, pois fez ressurgir, de forma inusitada, esse momento histórico à memória paranaense. Contudo, ao iniciarmos a leitura do que aparenta ser um romance histórico sobre um período já esquecido da história do Paraná, percebemos que as intenções do autor vão muito mais além do simples gesto de lembrar.
CONTATO LINGUÍSTICO EM CONTEXTO DE OBSOLESCÊNCIA LINGUÍSTICA
Authors: Gomes Simone Fonseca
Published: August 2022

Discute-se os desafios teórico-metodológicos da abordagem do contato linguístico em contexto de revitalização de línguas ameaçadas sob a ótica da sociolinguística. Línguas minoritárias com baixo prestígio social em intenso contato com uma língua dominante passam por processos de mudança linguística que podem levar à substituição linguística, na medida em que a língua dominada perde gradualmente suas funções comunicativas e entra em desuso. Estuda-se o caso do francoprovençal, língua regional falada na França, onde a expansão do francês, língua dominante de prestígio, resultou no confinamento dessa língua aos pequenos vilarejos e à vida rural, ocasionando perdas em termos linguísticos. Atualmente, movimentos de revitalização empreendem ações de valorização da língua e buscam difundi-la e conferir-lhe nova função na comunidade. Surgem, então, novos falantes os quais aprenderam a língua como segunda língua e que apresentam um desempenho fortemente marcado pelo contato com o francês, criando uma oposição em relação aos falantes nativos ou tradicionais que veem na performance dos primeiros uma versão corrompida da língua, afrancesada. O contato e seus efeitos aparecem assim como um fator perturbador, e a mudança linguística é vista como interferência da língua dominante e perda da língua minoritária, criando um impasse para a tarefa de revitalização.
O EXAGERO QUE PRECEDE O REAL: UMA RESENHA DE PRAÇA DOS HERÓIS, DE THOMAS BERNHARD
Authors: Schargel Sergio
Published: August 2022

Praça dos heróis, de Thomas Bernhard, foi lançado ao final da década de 1980, mas permanece mais atual do que nunca. Em resumo, a peça traz o suicídio de um professor, que se jogou de sua janela na Praça dos Heróis, em Viena. Através da uma estética pautada por proposital hipérbole, o objetivo de Bernhard é claro: mostrar, com o exagero da ficção, que o fascismo não morreu em 1945. E, mais do que isso, como o fenômeno de negação e o revisionismo da participação dos perpetradores acaba por facilitar a sua ascensão em novas vestes. Esta resenha discute a obra de Bernhard, em diálogo com outras obras do subgênero da literatura política, à luz dessas questões. A intenção é mostrar, através de uma discussão sobre a ficção, o perigo de se interpretar levianamente o nazifascismo como um fenômeno limitado ao início do século XX.
¿Qué llevar y qué no llevar a la clase?
Authors: Paula Vanderlei Andrade de
Published: August 2022

Es de sentido común que una de las ideas que más se difunde en el imaginario popular con respecto a la enseñanza de lenguas extranjeras es que esta actúa como una herramienta para que los aprendices de un idioma en particular lo dominen, lo que incluye el dominio de habilidades comunicativas como hablar y escribir, por ejemplo, así como la cultura relacionada. Tales concepciones no son incorrectas. Sin embargo, la enseñanza de lenguas extranjeras va más allá de la competencia o la inmersión cultural que ella misma proporciona. También puede ser un instrumento para fomentar la producción crítica de pensamiento en los alumnos. Bajo una metodología de alfabetización crítica, la enseñanza de una lengua extranjera también es un compromiso con el cambio social (TAGATA, 2018). En este artículo presentamos relatos de experiencias a partir de la enseñanza de español en el Curso de Línguas Aberto à Comunidade (CLAC / UFRJ), destinado a aprendices brasileños. Exponemos esos relatos con el objetivo principalmente mostrar algunas reflexiones que hicimos después de algunas clases en las que leemos algunos textos en español y mostramos algunos videos, que tenían temas que podemos considerar "espinosos", aunque que hubieral el compromiso de producir un pensamiento crítico que provoca el cambio social. Lo que nos llevó a reflexionar sobre tales prácticas se refiere a los resultados producidos en la clase: unos esperados, otros no. Creemos que esta reflexión es válida no solo para la enseñanza de español, sino también para la de cualquier otra lengua extranjera.

Purpose

This study aimed to evaluate the feasibility of defining an in vivo dosimetry (IVD) protocol as a patient‐specific quality assurance (PSQA) using the bead thermoluminescent dosimeters (TLDs) for point and 3D IVD during brachytherapy (BT) of gynecological (GYN) cancer using 60Co high‐dose‐rate (HDR) source.

Methods

The 3D in vivo absorbed dose verification within the rectum and bladder as organs‐at‐risk was performed by bead TLDs for 30 GYN cancer patients. For rectal wall dosimetry, 80 TLDs were placed in axial arrangements around a rectal tube covered with a layer of gel. Ten beads were placed inside the Foley catheter to get the bladder‐absorbed dose. Beads TLDs were localized and defined as control points in the treatment planning system (TPS) using CT images of the patients. Patients were planned and treated using the routine BT protocol. The experimentally obtained absorbed dose map of the rectal wall and the point dose of the bladder were compared to the TPSs predicted absorbed dose at these control points.

Results

Relative difference between TPS and TLDs results were −8.3% ± 19.5% and −7.2% ± 14.6% (1SD) for rectum‐ and bladder‐absorbed dose, respectively. Gamma analysis was used to compare the calculated with the measured absorbed dose maps. Mean gamma passing rates of 84.1%, 90.8%, and 92.5% using the criteria of 3%/2 mm, 3%/3 mm, and 4%/2 mm were obtained, respectively. Eventually, a “considering level” of at least 85% as pass rate with 4%/2‐mm criteria was recommended.

Conclusions

A 3D IVD protocol employing bead TLDs was presented to measure absorbed doses delivered to the rectum and bladder during GYN HDR‐BT as a reliable PSQA method. 3D rectal absorbed dose measurements were performed. Differences between experimentally measured and planned absorbed dose maps were presented in the form of a gamma index, which may be used as a warning for corrective action.
