A funcionalidade da política social e os limites da emancipação humana na ordem do capital
Authors: Oliveira Ednéia Alves
Published: May 2019

Este texto é resultado de uma pesquisa teórica construída ao longo do meu percurso acadêmico e que objetiva compreender a natureza das políticas sociais e do direito social na ordem burguesa. Para tanto faz-se necessário resgatar algumas premissas importantes presentes na obra marxiana, tais como mais valia, acumulação de capital, superpopulação relativa, o que inclui também a discussão presente em Marx sobre a questão da emancipação política e da emancipação humana. Neste sentido buscamos analisar, ainda que de forma sumária, como as políticas sociais são um elemento de manutenção e funcionalidade da ordem, podendo ser, de acordo com as interpretações comuns, um entrave para a emancipação humana e não uma forma objetiva de alcança-la. Portanto a desmisitificaçao destas categorias e sua funcionalidade na ordem burguesa é questão fundamental para superação do capitalismo e a construção de uma nova sociabilidade, o comunismo.

Authors: Santos Gabrielle Dos , Freitas Leana Oliveira , Gomes Crisanvania Luiz
Published: May 2019

O texto em tela toma como objeto de reflexão a educação superior no Brasil à luz da perspectiva teórica crítica. Busca empreender uma caracterização de como tem se desenvolvido as políticas públicas para este nível de ensino na particularidade histórica brasileira, o que exige a retomada de contexto em que se desenvolvem estas políticas, sobretudo, pós anos de 1970/80. Contexto em que as orientações dos organismos internacionais se intensificam no processo de desenvolvimento dos países periféricos. Busca-se, ainda, analisar dados estatísticos que revelam de que modo está configurado o acesso à educação superior no momento atual. Conclui-se que a emancipação humana corresponde a um estágio material e socialmente avançado de desenvolvimento de forças sociais humanas e somente sob uma nova ordem societária poderá ser a educação a forma de reciprocidade mutuamente benéfica entre os indivíduos particulares e sua sociedade.

Authors: Mendes Viana Buenos Aires Fábia de Kássia , GUIMARÃES SIMONE DE JESUS
Published: May 2019

O artigo discute a participação social sob a perspectiva de seu potencial emancipador, bem como sua utilização no Brasil, considerando seus avanços e retrocessos a partir da redemocratização do país face ao avanço do ideário neoliberal.A diversificação de espaços participativos é analisada sob a perspectiva de sua contribuição para o fortalecimento democrático das relações entre Estado e sociedade civil. Mediante uso de metodologia qualitativa, realizou-se uma revisão bibliográfica acerca do tema. Os resultados apontam para a relevância da participação da sociedade civil enquanto instrumento de emancipação, contudo revelam o seu desvirtuamento face ao ideário neoliberal, que a utiliza em prol de uma despolitização da sociedade e um engessamento de sua atuação.

Para tanto, o artigo analisa os diferentes projetos de industrialização em disputa no contexto pré-1964 e as suas consequências para a conformação da modernização conservadora brasileira.
DIREITOS, LUTAS SOCIAIS E “QUESTÃO DEMOCRÁTICA” NO BRASIL CONTEMPORÂNEO
Authors: Pereira Evelyne Medeiros , Elias Michelly Ferreira Monteiro
Published: May 2019

O artigo pretende desenvolver uma reflexão em torno dos principais aspectos do debate sobre direitos em Marx e na tradição marxista e sua relação com a particularidade da “questão democrática” na formação sócio-histórica brasileira, com destaque para seu caráter dependente em meio ao processo de desenvolvimento desigual e combinado do capitalismo. Sabendo que existem diferentes concepções e polêmicas sobre o tema em questão, foi priorizado um diálogo entre as elaborações clássicas sobre Estado, sua dimensão jurídica e política, e os fundamentos da realidade brasileira a partir de interpretações de relevância no âmbito do pensamento crítico no país. Atentou-se para as contradições que permeiam o Estado, os direitos e a democracia no capitalismo, considerando a luta de classes, suas expressões contemporâneas e o significado sócio-histórico dos direitos no Brasil. Para isso, desenvolveu-se um estudo bibliográfico, priorizando a perspectiva crítico-dialética e um caminho que confirma a vivacidade do tema em questão.
Trabalho escravo e atuação da CPT no sul e sudeste do Pará
Authors: Da Silva Lima Cristiane , Faria Pinheiro Luci
Published: May 2019

O presente artigo tem como objetivo analisar as transformações na economia agrária do sudeste do Pará que levaram à introdução do trabalho análogo ao escravo, a lógica que segue e a importância da atuação da CPT, Comissão Pastoral da Terra em seu combate. Utilizam-se fontes documentais e observações diretas como instrumento de pesquisa. Conclui-se que embora o controle do Estado seja insuficiente e isto confirme sua corresponsabilidade nessas relações, as unidades móveis de fiscalização têm efeitos positivos. Contudo, a participação da CPT tem sido historicamente a força mais importante na luta dos trabalhadores rurais frente aos conflitos de terra e à exploração do trabalho na economia agrária de capitalismo periférico na região.
Nova morfologia do trabalho, crise do sindicalismo e emancipação humana na contemporaneidade
Authors: Guarany Alzira Mitz Bernardes
Published: May 2019

Este artigo é parte de um estudo mais amplo acerca da saúde mental e do trabalho, de caráter bibliográfico e empírico. Tem a intenção de discutir a crise do capitalismo, a nova morfologia do trabalho promovendo inovações em suas formas de gestão e os rebatimentos desta conjuntura no movimento sindical e no projeto de emancipação humana. Ele se propõe a realizar uma análise crítica das lutas sociais históricas e dos processos organizativos da classe trabalhadora que vem sofrendo na contemporaneidade violentas ofensivas em diversas dimensões, dificultando a consecução de um projeto societário alternativo de emancipação humana ao mesmo tempo em que reafirma sua necessidade na medida em que assistimos nos últimos tempos a uma das mais nefastas tragédias sociais da humanidade, dando sinais da falência do projeto civilizatório proposto pela sociabilidade burguesa.
Educação, Inclusão Precária e a Politecnia como Estratégia Política dos Trabalhadores
Authors: Lima Jacqueline Aline Botelho
Published: May 2019

No presente texto, apresentamos a política de educação profissional no Brasil num contexto em que as políticas sociais públicas sofrem os impactos das alternativas neodesenvolvimentistas à crise capitalista. As políticas de alívio à pobreza e de inclusão precária imprimem direção à educação básica brasileira numa privatização do espaço público, operada em nome da democracia e da participação popular e numa formação aligeirada dos estudantes, em nome das necessidades de inserção da juventude no mercado de trabalho e de redução do desemprego. Neste contexto, a educação profissional é disputada por diferentes projetos de classe: os setores dominantes, representados pelo Sistema S e pelo agronegócio, defendem uma formação estritamente técnica, e os trabalhadores, representados por Movimentos Sociais como o MST nos apresentam um projeto de educação tecnológica, articulado à cultura e à ciência, cuja síntese encontra-se nas formulações de Marx sobre Politecnia.

Published: May 2019

O século XXI tem apresentado uma potencial crise do capital e mudança brusca nas relações de trabalho, com grande retração do emprego nos últimos dois anos. Tomando o estresse como manifestação do sofrimento humano no trabalho, esta pesquisa objetivou analisar os fatores relativos à incapacidade para o trabalho em uma amostra de trabalhadores, do setor privado, em licença saúde. Participaram 116 trabalhadores afastados por distúrbio osteomuscular e avaliou-se o estresse, o contexto de trabalho e a percepção da condição de afastamento, no período 2015 a 2016. A análise dos dados tomou como referência a Classificação Internacional da Funcionalidade-Incapacidade e Saúde e demonstrou que a incapacidade para o trabalho advém da relação entre condição de afastamento e contexto de trabalho. O sofrimento pela incapacidade se mostrou vinculado à manifestação do estresse. Conclui-se que os dados permitiram uma compreensão do cenário de incapacidade e sofrimento desta parcela da população.

Published: May 2019

Проаналізовані виробничі можливості сучасного парку промислових, фермерських та домашніх інкубаторів; визначені основні технічні проблеми їх конструкції. Недосконале обладнання вітчизняних побутових та практична відсутність фермерських інкубаторів а також відносно висока їх енергозатратність суттєво стримують виробництво продукції сільського птахівництва. На основі аналізу рівняння теплопередачі через стінки огороджувальної конструкції інкубатора визначені основні чинники, що суттєво впливають на втрати теплової енергії ним. Зроблений висновок про зменшення теплових втрат шляхом виготовлення огороджувальної конструкції інкубатора на основі сучасних теплоізоляційних матеріалів та заміни електромеханічної системи обертання інкубаційного матеріалу. Описано конструкцію оригінального енергоефективного інкубатора, що може бути виготовлений як у фермерському так і побутовому виконаннях і використаний на малих фермерських та присадибних господарствах. Для автоматичного локального та дистанційного керування параметрами мікроклімату інкубатора розроблена «інтелектуальна» автоматична система. Використання персонального комп’ютера в комплексі з мережею приладів «ТРЦ 02 Універсал+» вітчизняного виробництва дозволяє представляти вимірювані значення параметрів технологічного процесу інкубації в цифровій і графічній формах, а також локально та дистанційно керувати параметрами.

Published: May 2019

Предметом вивчення в статті є процеси побудови рекомендацій споживачами щодо вибору товарів та послуг, які реалізуються в рекомендаційних системах на основі врахування вибору схожих користувачів та відповідних властивостей товарів. Особливість таких процесів, полягає в тому, що при побудові рекомендацій враховуються інтереси схожих користувачів, але недостатньо уваги приділяється зміні патернів поведінки таких користувачів з часом. Мета полягає в розробці ситуаційного представлення користувацького вибору у вигляді багатошарового графу, кожний шар якого відображає об’єктну складову, а послідовність шарів – часову складову ситуації, що дозволяє врахувати зміни об’єктів інтересу споживачів. Задачі: виділити особливості вибору об’єктів користувачами рекомендаційних систем з урахуванням явного та зворотного неявного зв’язку; розробити ситуаційну модель користувацького вибору, що враховує зміни інтересів споживачів. Методами, що використовуються, є: методи побудови рекомендацій щодо вибору товарів та послуг на основі колаборативної фільтрації, методи побудови рекомендацій на основі контентної фільтрації. Отримані такі результати. Виділені особливості графового представлення взаємодії «користувач-обєкт» з урахуванням об’єктного та часового аспектів в рекомендаційних системах. Розроблено графову багатошарову ситуаційну модель користувацького вибору, яка враховує зміну потреб у виборі товарів та послуг у часовому аспекті. Висновки. Наукова новизна отриманих результатів полягає в наступному: Запропоновано ситуаційно модель користувацького вибору в рекомендаційній системі у вигляді багатошарового графу. Кожен шар моделі задається дводольним графом, вершини якого відповідають користувачам та об’єктам їх інтересу. Такий шар відображає зв'язок між користувачами та об’єктами на визначеному інтервалі часу. Ваги дуг графу відображають кількість вибраних користувачами об’єктів або рейтингову оцінку цих об’єктів для неявного або явного зворотного зв’язку відповідно. Послідовність шарів графу визначає зміну вподобань споживачів з часом. Зв’язки між шарами графу задаються через зв’язки між відповідними споживачами. Запропонована модель користувацького вибору дає можливість виділити ситуацію, в якій був здійснений вибір споживачами, схожими на поточного користувача рекомендаційної системи. Така ситуація характеризується підмножиною пар «користувач-обєкт». Відібрана підмножина пар в подальшому може бути використана для проведення колаборативної фільтрації, що дає можливість підвищити точність рекомендацій на основі врахування зміни інтересів споживачів у часі.

ADDITIONAL VALUE OF QUANTIFICATION OF MYOCARDIAL FIBROSIS BY CONTRAST-ENHANCED MRI TO IDENTIFY SUBJECTS WITH HYPERTROPHIC CARDIOMYOPATHY AND SUDDEN CARDIAC DEATH RISK
Authors: Komissarova S. M. , Zakharova E. Yu. , Ilyina T. V. , Vankovich E. A.
Published: May 2019

Background. A 5-year sudden cardiac death risk model in line with ESC-2014 (HCM Risk-SCD score) Guidelines assesses the risk of sudden cardiac death in individuals with hypertrophic cardiomyopathy using clinical parameters without taking into account magnetic resonance imaging indices including myocardial fibrosis.

Aim. To compare subjects with low, moderate, and high sudden cardiac death risks, identified based on HCM Risk-SCD score, with delayed enhancement magnetic resonance imaging-evidenced fibrosis and to assess the role of fibrosis in identification of patients with sudden cardiac death risk.

Material and Methods. A total of 98 patients with hypertrophic cardiomyopathy underwent an integrative examination including cardiac echocardiography, 24-h electrocardiography monitoring, delayed gadolinium-enhanced magnetic resonance imaging, and an assessment of a 5-year sudden cardiac death risk by HCM Risk-SCD score.

Results and Discussion. Out of 98 patients, 45 (46%) patients had low risk of sudden cardiac death, 26 (26%) patients had intermediate risk, and 27 (28%) patients had high sudden cardiac death risk by HCM Risk-SCD score. During the follow-up period, (mean 41 months; 25 to 58 months), 16 adverse events were registered: sudden cardiac death occurred in 9 patients while 7 patients had been successfully resuscitated and implanted with implantable cardioverter defibrillator for secondary prevention of sudden cardiac death. The risk assessment using HCM Risk-SCD score showed high risk in 8 out of 16 (50%) patients; 2 (12.5%) patients had moderate risk, while 6 (37.5%) patients had low risk. High-risk patients demonstrated significantly (p<0.001) larger fibrosis (mean 28.5%; quartiles 21.9%; 44.1%) compared to those with moderate risk (mean 17.6%; quartiles 8.0%; 22.5%) and low risk of sudden cardiac death (mean 11.7%; quartiles 5.8%; 17.6%). The volume of fibrosis by delayed contrast-enhanced magnetic resonance imaging was associated with the adverse outcomes rate, which was 15%. A Log rank test in the KaplanMeier survival analysis showed statistically significant differences (p=0,002) in groups with fibrosis <15% and≥15%. The regression analysis showed that myocardial fibrosis was more significant factor associated with sudden cardiac death (OR 12; 95% CI 1.6–91) compared to SCD ESC-2014 score (OR 2.8 95% CI 1.1–7.5).

Conclusion. Therefore, based on regression analysis, patients with hypertrophic cardiomyopathy who had myocardial fibrosis volume ≥15% were identified as a group with risk of sudden cardiac death and adverse arrhythmic events.

Published: May 2019

Aim of the study was to identify the effects of myocardial revascularization on the prognosis in patients with altered coronary blood flow detected by transthoracic ultrasound.

Material and Methods. Four hundred and twelve (412) patients were included in the study. The inclusion criterion was coronary velocity more than 70 cm/s during echocardiography. The study population was divided into three groups: Group 1 comprised patients with high velocities in the coronary arteries detected by ultrasound, in whom myocardial revascularization was performed; Group 2 comprised patients with high velocities in the coronary arteries, in whom myocardial revascularization was not performed and; the Control Group comprised patients with normal coronary blood flow according to ultrasound. The follow-up period was 10–11 months.

Results. Seventeen (17) deaths (4.7%) occurred during follow-up. Death rates were 1.6 vs. 8.1 vs. 0% in Group 1, Group 2 and the Control Group, respectively, with a p-value for the difference between Group 1 and Group 2 (p1) of <0.009; and a p-value for the differences compared with the Control group (р2) of <0.03. Death, myocardial infarction, pulmonary edema, and acute coronary syndrome were observed in 27 patients (7.7% of the study group with accelerated blood flow). The rates of these outcomes were 4.9 vs. 11.0 vs. 0% in Group 1, Group 2, and the Control Group, respectively (p1<0.05; p2<0.006). Discussion. The study showed high rates of mortality or acute coronary events in the group of patients with pathologically high coronary flow velocities. The positive effects of revascularization on survival in this group were verified.

Conclusions:

1. Left artery coronary flow velocities over 70 cm/s indicate a high probability of death or acute coronary events within 10.5 months.

2. Myocardial revascularization has a significant positive effect on the survival rate and incidence of acute coronary events in patients with coronary artery flow velocities greater than 70 cm/s.

Este artigo apresenta procedimentos para montagem e calibração de cinco sensores termohigrométricos, que foram desenvolvidos para a medição e estudos em ambientes urbanos, especificamente em transecto móvel utilizados em pesquisa de tese de doutorado. Os sensores utilizados nessa pesquisa foram do modelo DHT22 (medem a temperatura do ar e a umidade relativa do ar). O datalogger (registrador de dados) foi programado em placa microcontroladora Raspberry Pi 3. Observando-se a necessidade de aferição, os sensores foram registrados nas mesmas configurações e condições ambientais que o sensor padrão (HOBO U12-012). Foram realizadas análises estatísticas (comparações múltiplas) que constaram a real necessidade da calibração dos cinco sensores. Conclui-se que o termo-higrômetro confeccionado neste trabalho, após ser calibrado, apresentou medidas confiáveis e de boa qualidade. E que a metodologia se mostrou eficaz e confiável para o desenvolvimento e calibração dos sensores utilizados, contribuindo para que em outros estudos relacionados às medidas de variáveis da microclimatológicas sejam empregados e utilizados.

Geometry teaches us not only about how to give appreciation for something, but also how to find connections that occur between geometry material and other lecture material. In addition, geometry also trains communication through exploration, discussion, conjecture and investigation. The problems that exist in basic geometry skills in a row are problems related to logic skills, drawing skills, visual skills, verbal skills, and applied skills. Based on geometric learning using analytical presentation, the problem of using axiomatic deductive is at the top, then the problem of perception. Misconceptions about visual processes and activities, and finally problems with the use of procedures, concepts, and principles
