Entre produção, circulação e apropriação
Authors: Pinheiro Nara Vilma Lima
Published: July 2021

Por meio da reconstituição da trajetória profissional de Carleton Wolsey Washburne, este estudo procurou evidenciar as circunstâncias de produção suas ideias educacionais. Ao procurar saber mais sobre sua trajetória e suas ações educacionais, importantes redes de comunicação se revelaram, evidenciando que suas ações não foram isoladas, mas entrelaçadas a redes internacionais, cujos discursos e práticas foram incorporados por indivíduos e instituições adeptas da Éducation Nouvelle defendida pela New Education Fellowship [NEF]. De modo específico, interessa saber quais ideias de Washburne, os periódicos fundadores da NEF, fizeram circular internacionalmente. Para tanto, essa pesquisa se insere no campo da História da Educação e da História Cultural, utiliza-se da análise documental amparando-se nos estudos de Michel de Certeau e Peter Burke. Os resultados evidenciaram que a circulação das ideias de Washburne, via publicações da NEF, não privilegiou o conjunto de sua obra, mas os materiais autoinstrucionais, em especial os referentes ao ensino de aritmética.
Educação museal e produção de memórias
Authors: Farias Júnior José Petrúcio
Published: July 2021

O artigo discorre sobre a construção de memórias construídas pelo público-visitante a partir da narrativa museal, produzida pelo Museu Ozildo Albano (Picos/Piauí) e seus possíveis usos para o ensino de história. Para isso, faremos uso, de um lado, das representações sobre o passado veiculadas por essa instituição cultural; de outro, analisaremos as percepções de estudantes universitários que o visitaram. Sob esta ótica, relacionaremos o papel do museu ao âmbito da memória cultural, por meio da qual enfatizaremos a constituição da ‘memória protética’, tal como idealizada por Alison Landsberg (2009).
A temática da ‘educação pública’ na escrita da história da educação de Lorenzo Luzuriaga
Authors: Menezes Roni Cleber Dias de
Published: July 2021

O artigo trata do comparecimento da temática ‘educação pública’ na obra pedagógica do educador espanhol Lorenzo Luzuriaga, buscando uma compreensão acerca dos traços de sua escrita da história da educação que são dados a ver nos seus títulos que integram a Biblioteca del Maestro, coleção organizada por ele mesmo na Editorial Losada de Buenos Aires. Tais traços são pensados fundamentalmente a partir da análise do livro Historia de la educación pública, publicado em 1946, e também por intermédio da perscrutação da trajetória intelectual de Luzuriaga. Os procedimentos adotados intentam fornecer possíveis respostas às representações assumidas por uma noção cara ao seu professado escolanovismo, o da prerrogativa estatal na organização da educação, tomando-se por ângulo de observação uma das obras representativas do seu modo de escrita da história da educação. Os resultados da investigação apontam para o enquadramento da temática na perspectiva do internacionalismo que ganhava força com o final da Segunda Guerra Mundial e a criação de instituições de alcance global, como a Organização das Nações Unidas.
A Comissão Nacional de Moral e Civismo e a Mocidade Portuguesa
Authors: Gondim Amanda Marques de Carvalho
Published: July 2021

O artigo procura observar como aspectos da educação se apresentaram no Brasil e em Portugal em períodos históricos de regimes ditatoriais. Um dos discursos proferidos foi o que considerava a importância das tradições e sua manutenção para se atingir um estágio civilizacional superior ao vigente, tendo a educação escolar como principal dispositivo. A metodologia utilizada foi a observação de simetrias na categoria identidade nacional em textos do primeiro presidente da Comissão Nacional de Moral e Civismo [CNMC], no Brasil, e do primeiro comissário nacional da Mocidade Portuguesa [MP], em Portugal. Nos dois casos, foram encontradas afirmações acerca da produção da identidade nacional a partir da valorização das tradições, que deveriam ser preservadas e fomentadas na educação nos dois casos.

Authors: Garcia Gilberto Vieira , Silva Gustavo da Motta
Published: July 2021

O artigo pretende analisar as relações entre o ensino de música, de ginástica e de dança no contexto do ensino secundário, no Rio de Janeiro do século XIX. Para tanto, as análises centraram-se em torno do Imperial Colégio Pedro II, pela sua idealização como instituição modelar para o ensino secundário no país. A concepção das ‘Belas Artes’ que perdurou até o fim do oitocentos, integrando também a música, a ginástica e a dança, será uma base fundamental para as discussões desenvolvidas ao longo do texto. A categoria analítica ‘relação de vizinhança’, definida por André Chervel dentro do estudo da história das disciplinas escolares, foi relevante para o desenvolvimento dessas articulações, sobretudo, para se refletir sobre a importância dessas matérias no currículo escolar.

Temos como objetivos conhecer o impacto desses Congressos em Portugal; compreender a circulação e apropriação dessas ideias no contexto português - agentes ações e receção. O estudo situa-se entre 1872, ano da realização do I Congresso Penitenciário Internacional, pioneiro na atenção à problemática social da infância, e 1926, final da I República Portuguesa, momento de mudança de políticas sociais. Como fontes, recorremos a relatórios e obras produzidas por participantes nesses congressos, à Lei de Proteção à Infância, Portugal 1911, e suas alterações. Concluiremos com uma síntese das ideias divulgadas em Portugal e seus ecos nos normativos jurídicos até 1925.
Dificuldades de aprendizagem e de disciplina como constitutivas da escola moderna
Authors: Gualtieri Regina Cândida Ellero
Published: July 2021

Dificuldades de aprendizagem ou disciplina, que prejudicam o percurso escolar de crianças e resultam em repetência ou abandono, são aqui objeto de análise histórica. Verificamos como tais dificuldades são abordadas, nos anos 1930, na Revista de Educação, periódico criado pela Diretoria Geral da Instrução Pública de São Paulo em 1927. Identificamos, no corpus documental, que textos tratam dessas dificuldades e como são caracterizadas pelos autores. Nos textos, constatamos a existência de um ethos que culpabiliza a criança e seu entorno familiar e social por suas dificuldades. Em diálogo com a literatura, associamos a permanência desse ethos pedagógico com o modo de operar da escola moderna.
Fragmentos da história do ensino de sociologia no Brasil
Authors: Bodart Cristiano , Marchiori Cassiane da C. Ramos
Published: July 2021

Realiza-se a análise disposicionalista e contextualista do manual escolar Educação moral, noções de sociologia e direito usual, de Elpídio de Abreu e Lima Figueiredo, publicado em 1917. Trata-se, provavelmente, do primeiro manual escolar brasileiro de Sociologia destinado ao ensino secundário. O referido livro tinha por objetivo atender a legislação municipal do Rio de Janeiro, de 1916, que introduziu a disciplina ‘Educação moral, noções de sociologia e direito usual’ na Escola Normal daquele município. A análise volta-se para o manual escolar destacando o autor como ator plural, inserido em vários campos sociais e dotado de um estoque de habitus (Lahire, 2003) que auxilia a compreender, em algum grau, a produção de sua obra e, consequentemente, a história do ensino de sociologia no Brasil. Assim, observou-se uma proposta de ensino de sociologia imbricada com a moral, a psicologia e o direito, sem uma filiação teórica e, em muitos momentos, enciclopedista. A pesquisa destaca a importância da obra e suas características para a compreensão das bases históricas do ensino de sociologia no país.

Authors: Neves da Silva Carolina Mostaro
Published: July 2021

artigo analisa as discussões sobre educação nos trabalhos do Congresso Agrícola, Industrial e Comercial, ocorrido em Belo Horizonte, em 1903, evento significativo para a abordagem da interseção entre as demandas sociais, políticas, econômicas e educacionais dos produtores mineiros. Analisam-se as publicações, sobretudo da imprensa periódica, sobre a organização e a realização da reunião, e identificam-se várias propostas de instrução profissional, conforme níveis, métodos e finalidades. Essas propostas procuram responder à ausência de ensino profissional adequado, principalmente prático, tanto para produtores como para trabalhadores, e à convicção de que a educação desses últimos passaria pela organização das relações de trabalho e pelo combate à vadiagem.
High carriage rate of intestinal parasites among asymptomatic HIV-seropositive individuals on antiretroviral therapy attending the tertiary care hospital in Varanasi, India
Authors: Purbey Manish Kumar , Singh Aradhana , Kumari Simmi , Banerjee Tuhina
Published: July 2021

Introduction:

Infections by intestinal parasites (IPs) are prevalent among human immunodeficiency virus (HIV)-seropositive individuals. Although diarrhea is the usual manifestation, asymptomatic presentations are common. In such situations, the problem of parasitosis is often underestimated. This study was performed to assess the presence of IPs among asymptomatic HIV-seropositive patients.

Materials and Methods:

A case–control study was designed, including stool samples from 75 asymptomatic HIV-seropositive patients and 75 seronegative patients with gastrointestinal discomfort. IPs was identified by microscopy and polymerase chain reaction (PCR) for Entamoeba spp, Cryptosporidium and Microsporidium spp. The data were statistically analyzed using the Chi-square test.

Results:

The prevalence of IPs in HIV-seropositive cases (25.33%) was statistically significantly more (P < 0.05) than that of controls (4%). Helminths predominated in both the groups. PCR detected IPs in 5 (6.6%) additional microscopy-negative cases. The presence of IPs was associated with CD4 count <200 cells/μl.

Conclusion:

The asymptomatic carriage of IPs in HIV patients poses an important reservoir in the community. To prevent transmission, frequent screening is needed.
Assessment of preoperative thyroglobulin levels in papillary thyroid cancer
Authors: Melik Mehmet Ali , Baskonus Ilyas , Yilmaz Latif
Published: July 2021

Background:

The papillary thyroid cancers (PTCs) are the most common cancer of endocrine cancers. The primary treatment is surgery, and the prognosis is mostly well. In spite of many methods for the early diagnosis, the simpler and noninvasive methods are being sought. The aim of this study is to find out whether the value of thyroglobulin (Tg) is related with PTC.

Materials and Methods:

Prospectively; we measured the preoperative Tg value of 203 (159 females and 44 males) patients who underwent a total thyroidectomy with various indications in General Surgery Department of Gaziantep University. Tg values of 61 patients with benign lesions and 142 patients with PTC were compared.

Results:

In the patients with PTC, the mean preoperative Tg value was 105.05 ng/ml and 76.80 ng/ml in the benign patients. According to receiver operating characteristic analysis, the cutoff point was determined 102 ng/ml. There was a statistically significant difference in preoperative Tg values between benign group and PTC (P < 0.05).

Conclusion:

Patients with a preoperative Tg values above 102 ng/mL may more likely to have PTC. It is thought that Tg levels may be accepted as a criterion for distinguish malignant/benign situations that should be supported with new studies.

Authors: Moon Sun Young , Jo Yunhui , Seo Jaehyeon , Shin Dongho , Yoon Myonggeun
Published: July 2021

Introduction:

This study describes a simple method of inter-fractional photon beam monitoring to measure the entrance dose of radiation treatment using Gafchromic EBT3 film.

Materials and Methods:

The film was placed at the center of a 1-cm thick phantom shaped like a block tray and fixed on the accessory tray of the gantry. The entrance dose was measured following the placement of the film in the accessory tray. The dose distribution calculated with the treatment planning system was compared with the dose distribution on the irradiated EBT3 films. The effectiveness of this methodology, as determined by gamma passing rates, was evaluated for the 22 fields of eight three-dimensional conformal radiotherapy (3D-CRT) plans and the 41 fields of nine intensity-modulated radiotherapy (RT) plans. The plans for three-dimensional conformal RT included treatments of the rectum, liver, breast, and head and neck, whereas the plans for intensity-modulated RT included treatments of the liver, brain, and lung.

Results:

The gamma passing rates for 3D-CRT ranged from 96.4% to 99.5%, with the mean gamma passing rate for 22 fields being 98.0%. The gamma passing rate for intensity-modulated RT ranged from 96.1% to 98.9%, with the mean gamma passing rate for 41 fields being 97.7%. All gamma indices were over the 95% tolerance level.

Conclusions:

The methodology described in this study, based on Gafchromic EBT3 film, can be utilized for inter-fractional entrance dose monitoring as quality assurance during RT. Clinical application of this method to patients can verify the accuracy of beam delivery in the treatment room.

Authors: Koushik Kirthi , Janaki M. G. , Kumawat Rajesh , Paramesh Rangesh , Palaniyamma D
Published: July 2021

Introduction:

Oral mucositis is inflammation of the mucosa of the mouth which ranges from redness to severe ulceration. It results from the local effects of radiation to the oral mucosa.

Objectives:

The study is cumulative analysis of two studies (one comparative and the other open labeled) evaluated in individuals with oral mucositis during cancer radiotherapy and/or chemotherapy for the safety and efficacy of Oro-T mouthwash in a comparative design with normal saline.

Methodology:

Both the studies were similar with respect to clinical and laboratory parameters for analysis. The participants were advised to use 10 ml of Oro-T for 1 min 4 times daily for 6 weeks starting from day 1 of standard care. Patients were followed up, and the results were assessed from baseline on visit days: At entry and at the end of every week for 6 weeks. Clinical assessment of oral condition was done objectively (by the investigator) and also subjectively. Clinical symptoms such as sore throat, number of ulcer, burning sensation, pain, difficulty in chewing, difficulty in drinking, and mucositis grading along with Patient Reported Outcome Measures Scale were evaluated at each interval. Data was available for 40 subjects in Oro-T and 15 subjects in NS groups respectively.

Results and Conclusion:

The significant positive outcome was reported both subjectively and objectively in Oro-T group as compared to NS group with the delay in the onset of symptoms and less severe manifestation of oral mucositis with an improvement in quality of life. No adverse effects were reported that prompted discontinuation of study medication. Overall compliance to study medication was good.
Useful Health and Health Care Data from the Government
Authors: Baldwin Paul
Published: July 2021

We are constantly advised that intuition is a poor substitute for facts. While data and facts are not
always synonymous, most people will doubtlessly agree that data are generally more useful and
persuasive than opinion. Finding the data we need can be confusing and frustrating, but no entity
possesses and publishes more data than the US federal government. Some of these data are more
accessible than others, but if inquisitors are persistent and creative, then they can uncover a trove of information that can improve insights and increase contributions to organizations.
Microarray analysis of primary epithelial and fibroblast cells in chronic rhinosinusitis without nasal polyps
Authors: Ball S.L. , Cockell S.J. , Wilson J.A. , Mann D.A. , Fisher A.J.
Published: July 2021

Background: Chronic rhinosinusitis is an inflammatory condition with an as yet unknown pathophysiology. We aimed to detect clusters of differentially regulated genes in the epithelial and fibroblast cells of patients with Chronic Rhinosinusitis without nasal polyposis (CRSsNP) and healthy controls. Methodology: Carefully phenotyped CRSsNP and healthy control participants were recruited. Primary cultures of isolated epithelial and fibroblast cells were established. Whole transcriptome analysis of the cells was performed using microarrays and replicated with quantitative RT-PCR and immunohistochemistry. Results: Fibroblast cells from CRSsNP patients showed a significant upregulation (more than 2x) of the transcription factor NFE2L3 when compared to healthy controls by microarray with multiple hypothesis testing correction, qRT-PCR and immunohistochemistry. Conclusions: Here we have utilized microarray analysis to search for differentially expressed genes in isolated patient derived epithelial and fibroblast cells. The transcription factor NFE2L3 has been shown to be upregulated in fibroblast cells consistent with increasing evidence that fibroblasts play a key role in tissue specific inflammation within the paranasal sinuses.
Directional production of even carbon volatile fatty acids from peanut meal: effects of initial pH and hydraulic residence time
Authors: Chen Yujia , Fang Qian , Zhang Lu , Zhang Kequan , Wei Tong , Ping Qiqi
Published: July 2021

In this study, peanut meal was used as the substrate for the continuous production of even carbon volatile fatty acids (ECFA) through anaerobic fermentation. First, a continuous stirred reactor (CSTR) was started by adjusting the initial pH to acclimate the related bacteria, and then the hydraulic residence time (HRT) was optimized. The effects of different initial pH and HRT on the potential of ECFA production by peanut meal fermentation, the transformation and utilization of main organic compounds, and the composition and replacement of microbial community structure behind it were investigated. The results showed that ECFA was the dominant factor in the acid production of peanut meal fermentation, and alkaline pH and HRT = 6 d were the more favorable operating conditions for the hydrolysis and acidification of peanut meal. The average concentration of total volatile fatty acids (TVFAs) obtained was 15,249.50 mg/L, and the content of ECFA varied from 88.51% to 96.27%, with an average ratio of 92.55%. This operation condition drove the formation of microbial community structure, mainly including Prepotella, Tepididimicrobium, Anaerosalibacter, and Igatzschineria, which were favorable for ECFA production, reflecting the potential of using peanut meal for targeted production of ECFA.
Analysis of a mosquito life cycle model
Authors: Kouchéré Albert , Abboubakar Hamadjam , Damakoa Irepran
Published: July 2021

The gonotrophic cycle of mosquitoes conditions the frequency of mosquito-human contacts. The knowledge of this important phenomenon in the mosquito life cycle is a fundamental element in the epidemiological analysis of a communicable disease such as mosquito-borne diseases.In this work, we analyze a deterministic model of the complete life cycle of mosquitoes which takes into account the principal phases of female mosquitoes' gonotrophic cycle, and the Sterile Insect technique combined with the use of insecticide as control measures to fight the proliferation of mosquitoes. We compute the corresponding mosquito reproductive number N ∗ and prove the global asymptotic stability of trivial equilibrium. We prove that the model admits two non-trivial equilibria whenever N^{∗} is greater than another threshold, N_c, which the total number of sterile mosquitoes depends on. Numerical simulations, using mosquito parameters of the Aedes species, are carried out to illustrate our analytical results and permit to show that the strategy which consists in combining the sterile insect technique with adulticides, when it is well done, effectively combats the proliferation of mosquitoes.
A Multi Ant Colony Optimization Approach For The Traveling Salesman Problem
Authors: SOH Mathurin , Nguimeya Tsofack Baudoin , Tayou Djamegni Clémentin
Published: July 2021

In this paper, we propose a new approach to solving the Traveling Salesman Problem (TSP), for which no exact algorithm is known that allows to find a solution in polynomial time. The proposed approach is based on optimization by ants. It puts several colonies in competition for improved solutions (in execution time and solution quality) to large TSP instances, and allows to efficiently explore the range of possible solutions. The results of our experiments show that the approach leads to better results compared to other heuristics from the literature, especially in terms of the quality of solutions obtained and execution time.
French vital records data gathering and analysis through image processing and machine learning algorithms
Authors: Plateau-Holleville Cyprien , Bonnot Enzo , Gechter Franck , Heyberger Laurent
Published: July 2021

Vital records are rich of meaningful historical data concerning city as well as countryside inhabitants that can be used, among others, to study former populations and then reveal the social, economic and demographic characteristics of those populations. However, these studies encounter a main difficulty for collecting the data needed since most of these records are scanned documents that need a manual transcription step in order to gather all the data and start exploiting it from a historical point of view. This step consequently slows down the historical research and is an obstacle to a better knowledge of the population habits depending on their social conditions. Therefore in this paper, we present a modular and self-sufficient analysis pipeline using state-of-the-art algorithms mostly regardless of the document layout that aims to automate this data extraction process.

Research on De-noising of Downhole Engineering Parameters by Wavelet based on Improved Threshold Function
Authors: Luo Ming , Ge Liang , Xue Zhibo , Zhang Jiawei , LI Yanjun , Xiao Xiaoting
Published: July 2021

The measurement of downhole engineering parameters is greatly disturbed by the working environment. Effective de-noising methods are required for processing logging-while-drilling (LWD) acquisition signals, in order to obtain downhole engineering parameters accurately and effectively. In this paper, a new de-noising method for measuring downhole engineering parameters was presented, based on a feedback method and a wavelet transform threshold function. Firstly, in view of the mutability and density of downhole engineering data, an improved wavelet threshold function was proposed to de-noise the signal, so as to overcome the shortcomings of data oscillation and deviation caused by the traditional threshold function. Secondly, due to the unknown true value, traditional single denoising effect evaluation cannot meet the requirements of quality evaluation very well. So the root mean square error (RMSE), signal-to-noise ratio (SNR), smoothness (R) and fusion indexs (F) are used as the evaluation parameters of the de-noising effect, which can determine the optimal wavelet decomposition scale and the best wavelet basis. Finally, the proposed method was verified based on the measured downhole data. The experimental results showed that the improved wavelet de-noising method could reduce all kinds of interferences in the LWD signal, providing reliable measurement for analyzing the working status of the drilling bit.

Green Military New Deal
Authors: Castillo-Vinuesa Eduardo , Gankevich Iuliia
Published: July 2021

Among the most decisive challenges that the climate crisis will bring during up coming decades will be the necessity to overcome the current lack of planetary ecosystem governance. The void that exists where proper geopolitics should reside demands a recalibration of the focus of design towards the conception, implementation, and support of new institutional models capable of reconfiguring established infrastructural, ecosystem and governance structures.

The rising awareness of the lack of ecological agency has recently led to the emergence of several proto-policies branded under the name of “Green New Deals” (GNDs): the green proposals across the world that aim to address climate change and economic inequality. However, the implementation of the GND’s goals requires not only the necessary infrastructural means for decarbonisation but also a set of social insurance mechanisms able to guarantee social stability during the transition to a new energy regime.

The complexity that this task poses in relation to society, the economy, manufacturing industries and goods and information logistics will require the establishment of an institution capable of intervening in the regulation and coordination of all the parties involved.

Green Military New Deal (GMND) is a research proposal that lies between the legislative models of ecosystem governance and the institutions capable of enforcing them. It speculates about the military establishment as a proto-platform that could fulfil the institutional gap created by the GND’s demands. Would it be possible to reimagine the military establishment as a trans-national ecological force capable of mobilising and enforcing proper ecosystem management, conscious of its ability to act as a welfare provider while deploying its technological resources?

Our research offers an informed approach toward this counterintuitive premise, uncomfortable as it may be, by forcing us to question how certain existing institutions could be properly repurposed to address issues of global necessity.

FORMAÇÃO PROFISSIONAL EM SERVIÇO SOCIAL E POLÍTICA DE EDUCAÇÃO SUPERIOR NO ÂMBITO DAS IES DO PROCAD-AMAZÔNIA
Authors: Lúcia Batista Gomes Vera , Daltro Tavares Paiva Sara , Camille Marques Cezar Karina
Published: July 2021

Este artigo teve o propósito de analisar a formação profissional e a política de educação superior no Brasil, com breves destaques para o contexto da pandemia provocada pelo COVD-19. Foi baseado em análises sobre a produção de conhecimento de dissertações e teses sobre formação profissional e política de educação, desenvolvidas nos Programas de Pós-Graduação em Serviço Social das IES que integram o PROCAD/Amazônia (2018), assim como, de experiências vivenciada pelas autoras com o ERE. A luz da teoria marxista, os resultados apontam que tanto nas universidades públicas federais quanto nas privadas, devido ao sucateamento e a precarização do ensino superior, decorrentes das medidas ultraneoliberais expressas na restrição orçamentária para a política de educação superior e no contexto pandêmico, a formação em Serviço Social vem sendo ameaçada, tornando-se imperiosas as lutas coletivas para o acesso aos direitos da classe trabalhadora.
A EDUCAÇÃO SUPERIOR E A PESQUISA EM RISCO
Authors: Costa Ana Carla da , Caputi Lesliane , Silva Diego Tabosa da
Published: July 2021

Neste texto trazemos à baila reflexões desenvolvidas coletivamente para fins de subsidiar os debates travados em live realizada na Semana de Serviço Social da Universidade Estadual de Montes Claros/UNIMONTES em 2020. Na ocasião discutimos, levando em consideração o contexto da pandemia COVID-19, a importância de grupos de estudos e pesquisa na educação superior, em especial num momento de os ataques frontais que a pesquisa, em especial na área das ciências sociais tem sofrido no atual governo federal - de caráter ultraneoliberal, neoconservador e de características fascistas. A partir da realização de uma pesquisa bibliográfica, construímos este texto pautando a análise da realidade pelo método dialético-crítico e aqui forjamos nossa posição ético-política de compromisso com as trincheiras de lutas da classe trabalhadora, pelas quais seguem sendo ímpar as articulações com os movimentos sociais e os diversos coletivos de defesa desta classe sempre espoliada pela subalterna burguesia brasileira (subalterna ao grande capital estrangeiro).
TRANSFORMAÇÕES NO MUNDO DO TRABALHO E SERVIÇO SOCIAL
Authors: Costa de Souza Victor , Luzia Leite Janete
Published: July 2021

Este texto objetiva analisar os impactos da reestruturação produtiva nos espaços sócio-ocupacionais reestruturados dos assistentes sociais, buscando identificar os reflexos na saúde desses trabalhadores. Para tanto, utilizamos o Sistema Único de Assistência Social como exemplo. O ponto de partida é a compreensão das transformações no mundo do trabalho em curso desde a década de 1970 no plano internacional. No Brasil, as alterações nas formas de gestão e regulação do trabalho se mesclam às particularidades históricas do país, economicamente subordinado aos centros econômicos. A partir da corrosão do trabalho formal e regulamentado, ampliam-se as manifestações de sofrimento e adoecimento laboral. Parte-se do pressuposto de que os assistentes sociais atuam nessas refrações da “questão social” e, ao mesmo tempo, as experienciam na condição de assalariamento. Metodologicamente, revisamos a bibliografia de autores vinculados a teoria social de Marx que tratam sobre a reestruturação produtiva e as suas consequências. No que concerne ao debate sobre o Serviço Social, utilizamos como marco teórico as contribuições de Marilda Iamamoto, José Paulo Netto, Ana Elizabete Mota e Raquel Raichelis. A fim de contemplar a discussão sobre o SUAS como espaço sócio-ocupacional, recorremos a textos e pesquisas acerca da política de Assistência Social e as demandas postas aos assistentes sociais. Para refletir sobre as situações de sofrimento e adoecimento laboral utilizamos resultados de pesquisas anteriores. Verificou-se que a retração e desregulamentação do trabalho impactam na relativa autonomia profissional dos assistentes sociais, gerando conflitos éticos e sofrimento mental diante da impotência de exercer uma prática profissional digna.

Steganography uses a Pixel Algorithm to Hide Image
Authors: Kumar C Vijaya , Babu G S Udaya Kiran
Published: July 2021

Steganography is a way of hiding data in the context of an image, preventing a person from finding it by mistake. This is an explicit text file with an image file. Due to the need for steganography, we have proposed a new algorithm called the use of steganography. In our algorithm, we should have a cover and a message. It can be pixel-for-pixel in an image. In it, we will have to use every bit of encryption. This process will continue until the final track of encryption. After this step, the data is hidden in the image. We will send the image file to the client, and the client will need to change the process to download the source code to the image.

RESUMO

Este artigo apresenta uma proposta diferenciada de uma nova metodologia de ensino, apoiada por ferramentas computacionais que podem contribuir para a melhoria do aprendizado dos alunos do Curso Técnico em Informática do Instituto Federal do Norte de Minas Gerais (IFNMG), Campus Arinos. As dificuldades encontradas pelos alunos na elaboração de um raciocínio estruturado para a solução de um problema computacional, de compreensão de conceitos, e a complexidade dos ambientes de desenvolvimento são, frequentemente, obstáculos ao aprendizado. Tais problemas podem ser amenizados pelo uso didático de novas plataformas, construídas para facilitar à aprendizagem pela experimentação. Com o intuito de tornar as aulas atrativas, objetivas e com o foco no aluno, pretende-se aplicar a Plataforma Arduino que é uma excelente ferramenta para o ensino de conceitos de Lógica de Programação, além de ser um vasto repositório de recursos para experimentação prática, e um laboratório de baixo custo para testes de programas em C/C++. O Arduino une essas ferramentas, resultando num ambiente de aprendizado fácil, com recursos de interfaceamento para sensores e atuadores. A aplicação coordenada do Arduino, no contexto da disciplina Algoritmos, pode conduzir o aluno a um aprendizado facilitado, consistente e voltado a aplicações práticas.

 

ABSTRACT

This article presents a differentiated proposal of a new teaching methodology, supported by computational tools that can contribute to the improvement of the learning process of students of the Technical Course in Computer Science of the Federal Institute of Northern Minas Gerais (IFNMG), Arinos Campus. The difficulties faced by students in developing a structured reasoning to solve a computational problem, understanding concepts, and the complexity of development environments are often obstacles to learning. These problems can be alleviated by the didactic use of new platforms, built to facilitate learning through experimentation. In order to make the classes attractive, objective and student focused, we intend to apply the Arduino platform, which is an excellent tool for teaching Logic Programming concepts, besides being a vast repository of resources for practical experimentation, and a low cost laboratory for testing C/C++ programs. Arduino brings these tools together, resulting in an easy learning environment with interfacing capabilities for sensors and actuators. The coordinated application of Arduino, in the context of the Algorithms course, can lead the student to a facilitated, consistent, and practical learning experience.
"Quantification of Incremental Benefits and Change in Input Use Pattern under Laser Land Levelling in comparison with Conventional Land Levelling in Haryana"
Authors: Kumar Dinesh ,
Published: July 2021

The investigation aimed to find monetary benefits of Laser Land Levelling (LLL) compared to conventional land leveling (CLL) in Karnal and Sirsa district of Haryana. These two districts were selected purposively because these have the highest area under paddy-wheat and cotton-wheat cropping patterns, respectively. The equation of Aryal et al. (2014) was explicitly used to estimate incremental benefits from laser land leveling. Also, input use pattern of machine labor, seed, plant protection chemicals, human labor, yield, and irrigation was considered. In the paddy-wheat cropping pattern of Karnal district, the annual net benefits of using laser land levelling were estimated to be ` 11450.81. In contrast, per LLL operation, net benefits were estimated to be ` 34352. Similarly, on the same lines in the cotton-wheat cropping pattern of Sirsa district, the annual net benefits of LLL were estimated to be ` 7212.61. In contrast,per LLL operation, net benefits were estimated to be ` 28850. As far as the input use pattern is concerned, the study showed that machine labour and yield increased under LLL while in both districts. In contrast, all other inputs i.e., seed, fertilizer, human labor, plant protection, chemicals, irrigation, were reduced, showing resource conservation potential of LLL. Hence, the study recommended adopting this resource conservation technology and tapping its potential benefits so that farmers may get benefitted from this ultimate technology
"Perspectives Fiscal Policy as a Stabilization Tool: Discretionary and Non Discretionary Policies"
Authors: Yadav Swati
Published: July 2021

Global financial crisis of 2008 and the Covid 19 led slowdown have brought Keynesian fiscal stabilization policies back to the forefront of all academic debates. But what the world is experiencing should be treated as an exceptional situation that should not be used to advance the case to fine-tune the economy every time using discretionary fiscal measures. The pre-crisis broad macroeconomic consensus still holds, and stabilization should first be left to monetary policy. On the fiscal front government should rely more on rule-based inbuilt stabilizers for short-term management of cyclical fluctuations in case of demand shocks and long-run fiscal policy should focus more on growth and developing enabling factors to attract more investment. Fiscal stabilizers on the expenditure side should be strengthened to provide an adequate safety net to economically vulnerable sections of the society.

Authors: Singh Hari
Published: July 2021

The present study was conducted to evaluate the improved integrated farming system performance at the fields of 30 selected tribal farmers of three selected villages of Vallabhnagar tehsil of Udaipur district (Rajasthan) during 2018-19 and compared with the benchmark year 2015-16. Various interventions from MPUAT experts were provided regarding inputs and their timely use and the training programs for these farmers. It was concluded that during 2018-19 FS IV (Crop + Dairy + Vegetable) and FS V (Crop + Dairy + Vegetable + Fruit Orchard) were highly efficient as these systems gave the highest returns per rupee of investment. In contrast, FS VIII (Crop + Dairy + Goat + Vegetable + Fruit Orchard) was efficient in terms of employment generation as it leads to the generation of 463 man-days. As a result, higher profitability and productivity with the lesser cost of cultivation of improved integrated farming system were obtained compared to the existing integrated farming system during the benchmark year.

Published: July 2021

The present paper studies the growth and fruiting processes of two Aronia melanocarpa cultivars, ‘Melrom’ and ‘Nero’, in the pedo-climatic conditions of the Muntenia (Arges) area, Romania. On average, over the whole experience, the ‘Merlom’ cultivar recorded a bush volume of 0.72 m3, annual vegetative growth of 0.38 m3, productivity of 1.88 kg of fruit per plant, and a ratio between fruit yield and the annual vegetative growth of 6.54 kg/m3. In the ‘Nero’ cv., the volume occupied by the aerial part of the bush was 1.98 m3, with an annual vegetative growth of 0.43 m3, an yield of 3.14 kg of fruits per plant, and, reported to the annual vegetative, fruit production was 10.64 kg/m3. Although the volume of the aerial part of the plant and the fruit production per plant were significantly higher in ‘Nero’ cultivar, ‘Melrom’ was noted by a larger ratio of fruit production to the unit volume of the aerial part of the plant, of 3.28 kg/m3. As resulted from our study, both cultivars presented valuable yielding potential.
