Background/Aims: To evaluate the effectiveness and safety of direct acting antivirals (DAAs) available in chronic kidney disease (CKD) patients with hepatitis C virus (HCV) infection in Korea.Methods: In a retrospective, multicenter cohort study, 362 patients were enrolled from 2015 to 2019. The effectiveness and safety of DAAs including glecaprevir/pibrentasvir, sofosubvir/ribavirin, ledipasvir/sofosbuvir, and daclatasvir/asunaprevir were analyzed for patients according to CKD stage. We evaluated sustained virologic response at week 12 after treatment (SVR12) as primary endpoint. The effectiveness and safety were also evaluated according to CKD stage.Results: Among 362 patients, 307 patients completed DAAs treatment and follow-up period after end of treatment. The subjects comprised 87 patients (62 with CKD stage 3 and 25 with CKD stage (4–5), of whom 22 were undergoing hemodialysis). HCV patients with CKD stage 1 and 2 (estimated glomerular filtration rate [eGFR] ≥ 60 mL/min/1.73 m2) showed SVR12 of 97.2% and 95.4% respectively. SVR12 of CKD stage 3 and 4–5 (eGFR < 60 mL/min/1.73 m2) patients was 91.9% and 91.6% respectively. Patients undergoing hemodialysis achieved SVR12 (90.9%). Treatment failure of DAAs in stage 1, 2, 3, and 4–5 was 2.8%, 2.7%, 1.6%, and 4%. DAAs showed good safety profile and did not affect deterioration of renal function.Conclusions: DAAs shows comparable SVR12 and safety in CKD patients (stage 3, 4, and 5) with HCV compared with patients with stage 1 and 2. The effectiveness and safety of DAAs may be related to the treatment duration. Therefore, it is important to select adequate regimens of DAAs and to increase treatment adherence.

Mice were divided in four groups: Control AIN-93, AIN-93+Madagascar cockroach flour (AIN93+CF), high-fat diet (HFD) and HFD+Madagascar cockroach flour (HFD+CF). The groups were treated for eight weeks (4 weeks of obesity induction + 4 weeks supplemented with CF isocaloric diet). Body composition, biochemical levels and molecular markers were evaluated. The main results showed a decreased fasting glucose, total cholesterol, triglycerides, and pyruvic transaminase/aspartate aminotransferase in the HFD-CF treated animals compared to HFD. Moreover, it was observed a decreased liver interleukin-6 (IL-6) and tumour necrosis factor alpha (TNF-α) inflammatory markers expression in HFD+CF mice. These data reveal that Madagascar cockroach flour may be a useful dietary supplement to improve biochemical and inflammatory obesity alterations.
Transformer with progressive sampling for medical cellular image segmentation
Authors: Jiang Shen , Li Jinjiang , Hua Zhen
Published: August 2022

The convolutional neural network, as the backbone network for medical image segmentation, has shown good performance in the past years. However, its drawbacks cannot be ignored, namely, convolutional neural networks focus on local regions and are difficult to model global contextual information. For this reason, transformer, which is used for text processing, was introduced into the field of medical segmentation, and thanks to its expertise in modelling global relationships, the accuracy of medical segmentation was further improved. However, the transformer-based network structure requires a certain training set size to achieve satisfactory segmentation results, and most medical segmentation datasets are small in size. Therefore, in this paper we introduce a gated position-sensitive axial attention mechanism in the self-attention module, so that the transformer-based network structure can also be adapted to the case of small datasets. The common operation of the visual transformer introduced to visual processing when dealing with segmentation tasks is to divide the input image into equal patches of the same size and then perform visual processing on each patch, but this simple division may lead to the destruction of the structure of the original image, and there may be large unimportant regions in the divided grid, causing attention to stay on the uninteresting regions, affecting the segmentation performance. Therefore, in this paper, we add iterative sampling to update the sampling positions, so that the attention stays on the region to be segmented, reducing the interference of irrelevant regions and further improving the segmentation performance. In addition, we introduce the strip convolution module (SCM) and pyramid pooling module (PPM) to capture the global contextual information. The proposed network is evaluated on several datasets and shows some improvement in segmentation accuracy compared to networks of recent years.
Musical Testimonies of Terezín and the Possibilities of Contrapuntal Listening
Authors: Wlodarski Amy Lynn
Published: August 2022

Taking my cue from the postcolonial cultural analyses of Edward Said, as well as a recent postcolonial turn in Holocaust studies, I define a practice of contrapuntal listening for the copious musical witness that constitutes the extensive Holocaust testimonial archive. Contrapuntal listening recognizes the inherent power dynamics and potential narrative desires present within the capture of testimony, a process that is never ideologically blank and is often driven by the explicit goals of the interviewers (amateurs and experts alike), whose relationship to the traumatized individual before them ranges from the empathetic to the antagonistic. This essay attempts to listen contrapuntally to one documentary source concerned with Viktor Ullmann’s musical activities in Terezín: Goethe och Ghetto (1996), the award-winning film directed by Peter Berggren and Göran Rosenberg. My analysis places the original witness testimonies collected for the project in contrapuntal conversation with the final documentary to illuminate its intentional “voicing” of three survivors as well as the power dynamics inherent in the testimonial exchange. My aim is not to cast aspersions, but to call for increased attention to these varied counterpoints as we expand our understanding of music’s roles in multivocal spaces like Terezín. To do so is to begin to enable a self-critical exchange with musical testimonies that considers their engagement within historical networks of power and authority.
Mixed Motives: Soviet Symphonies and Propagandistic Duplicity in The Iron Curtain (1948)
Authors: Platte Nathan
Published: August 2022

For Darryl Zanuck’s anti-communist film The Iron Curtain (1948), music director Alfred Newman compiled a score from the symphonic works of Shostakovich, Prokofiev, Khachaturian, and Myaskovsky. The Soviet selections remained even after legal efforts on behalf of the composers sought to remove them. Scholarship on The Iron Curtain has acknowledged the courtroom wrangling but not the capacity for outside music to sustain and complicate a propagandistic narrative. This article considers Newman’s setting of music within the film, which shifts from the spare, predominantly diegetic musical accompaniments used in Zanuck’s other “semidocumentaries” to a style patterned after pro-Soviet Hollywood films made during World War II in which Russian musical selections encouraged sympathetic audience responses. Drawing upon contemporary press coverage and production materials, this study shows how The Iron Curtain’s unusual compilation soundtrack both affirms and subverts ideologies imposed upon it.

Authors: Rangayya  , Virupakshappa  , Patil Nagabhushan
Published: August 2022

In this research, a new level set-based segmentation algorithm was proposed for human face segmentation. At first, the human facial images were collected from face semantic segmentation (FASSEG) dataset. After collecting the images, pre-processing was accomplished by utilizing contrast limited adaptive histogram equalization (CLAHE). The undertaken methodology effectively improves the quality of facial images by removing the unwanted noise. Then, segmentation was done by using adaptively regularized kernel-based fuzzy clustering means (ARKFCM) clustering with level set, which was a high-level machine learning algorithm for localizing the face parts in complex template. Simulation outcome shows that the proposed segmentation algorithm effectively segments the facial parts in light of precision, recall, Jaccard coefficient, dice coefficient, accuracy, and miss rate. The proposed segmentation algorithm enhanced the segmentation accuracy in face segmentation up to 4.5% compared to the existing methodology (pixel wise segmentation).

Published: August 2022

Self-adaptive mobile web service (MWS) discovery in Smart Systems depends on heterogeneous context-sensitive attributes that are composed dynamically to satisfy the user’s MWS request despite the constantly changing environment. Several ontologies are developed to deal with the issues of heterogeneous knowledge representation in smart systems. Unfortunately, these ontologies are mostly inexpressive, unextendible, constricted, and slightly fragmented due to a lack of socially focused ontology development procedures. In this paper, a context ontology for self-adaptive MWS discovery in smart systems is proposed to provide a better representation of the heterogeneous context for smart systems and facilitate the delivery of MWS. The lightweight unified process for ontology building (UPON Lite) is adopted for ontology development. The ontology is experimentally evaluated in protégé using real-world smart systems from the healthcare and agriculture domain. Consequently, the ontology was found to be more expressive, extensible, and support self-adaptive MWS discovery in Smart Systems.

Published: August 2022

Several parameters are required to improve Tire dynamic performances like high wet and dry traction (Grip), high wear resistance and high steering performance (handling). These performances depend on the physical properties of tire tread compound, tire construction, tread profile and road conditions. The most influential one is the reinforcing filler, which is responsible for inheriting the tread dynamic properties. Conventionally, carbon black is used as filler but it possesses a major hitch of CO2 emission during manufacturing as well as in service conditions. Its high rolling resistance is responsible for boosting the carbon footprint of a vehicle. In the past few decades, the focus has been shifting on silica fillers, an emerging technology to develop low rolling resistance tires resulting in low CO2 emissions thus contributing in the establishment of a healthy eco system. Design of Experiment (DOE) approach is used therefore, sixteen (16) variants of silica based compounds were prepared and properties of silica based samples were compared with that of carbon black compounds (conventional). The results revealed that this emerging silica filler showed promising results in giving the highest possible wet traction and lowest rolling resistance to minimize CO2 (Greenhouse gas) in the environment.

Published: August 2022

This paper introduces the braided helically wrapped yarns with negative Poisson’s ratio (NPR) exhibiting a stable structure and good practicability to avoid slippage of wrapped component from the core. The geometry and auxetic behavior of the braided helical structure for two different combinations of core materials with similar combination of wrap materials and different braiding angles have been analyzed. Two elastomeric materials i.e. Polyurethane (PU) and Polyester, were used as monofilament cores whereas two stiffer multifilament wrap yarns employed were, ultra-high molecular weight polyethylene (UHMWPE) and polyethylene terephthalate (PET). Multiple braided yarns were investigated to analyze materials’ behavior towards NPR. It was observed that the NPR strongly depended on the inherent properties of the core and wrap materials in addition to the braiding angle. The NPR value was higher for a core with relatively higher elasticity (e.g., PU elastomer compared with polyester). It was also noticed that a lower wrap angle and lower braiding speed exhibited higher NPR. The maximum NPR value using PU core wrapped at a low angle of 9° was-1.70, when tested at a low strain rate of 0.5%.

Published: August 2022

This study reports the ballistic penetration performance of a composite material composed of woven Kevlar® fabric impregnated with a colloidal shear thickening fluid (STF). STF comprised of Nanosized silica particles suspended in polyethylene glycol. The impregnated Kevlar fabric offers equivalent low velocity ballistic performance, on an areal density basis, to neat Kevlar fabric. Compared to neat Kevlar fabric, however, the STF-impregnated composites require fewer layers of Kevlar, resulting in a more flexible and less bulky body armor material. Possible mechanisms responsible for the enhanced ballistic and stab performance of the STF-Kevlar composite are identified.

Published: August 2022

Silver nanoparticles were synthesized using locally purchased honey and silver nitrate solution. This method provides a simplistic and straightforward approach to the formation of silver nanoparticles. The silver nanoparticles with varying amounts of silver nitrate solution were characterized using ultraviolet-visible spectroscopy and Fourier transform infrared spectroscopy. In addition, dynamic light scattering characterization was used to determine the average size and size distribution of silver nanoparticles. Experimental results revealed that varying the amount of silver nitrate solution can control the size and absorption spectra of silver nanoparticles. A large amount of silver nitrate solution will exhibit a peak in the higher wavelength. The shifting of the absorption peaks at 401, 406, 407, 408, and 409 nm are believed to be related to the wavelength of the surface plasmon resonance. Moreover, a larger amount of silver nitrate solution also results in an increasing size with 27.2, 57.9, and 63.4 nm as revealed in the size distribution via dynamic light scattering. This green synthesis method of silver nanoparticles will provide a cost-effective production as an alternative to commercial antibacterial agents.
Formation of Oxide Layer and Wettability on the Surface of Electrical Discharge Machining-Based Implant Engineered by Micro-Finishing
Authors: Qosim Nanang , Supriadi Sugeng
Published: August 2022

The ability to promote rapid osseointegration is an important criterion on the titanium implant surface. This performance is greatly determined by the roughness, wettability, and composition of the implant surface. This study aims to investigate the oxide layer formation and wettability on the EDM-titanium implant surface engineered by different micro-finishing methods (i.e. mechanical, physical, and chemical processes). The oxide layer formation was investigated by observing the wt% of oxygen formed while the wettability criterion was studied by determining the contact angle between the liquid and solid surface. The result reveals that the oxide layers formed on the sample surface, excepting Sulfuric acid (H2SO4) 95%-etched, show an interaction with the surface roughness and its wettability. The smoother the surface roughness of the sample, the lower the percentage of the oxide layer and the contact angle formed on the sample surface. In this aspect, the ultrasonic cleaning benchmark has the highest percentage by altering 18.84% of the oxide layer formed by the EDM process while the decrease of 75.89% generated by the H2SO4-etching is the lowest one. On the other hand, the higher the percentage of the oxide layer formation, the lower the wettability of the sample surface. In this aspect, the ultrasonic cleaning benchmark has the lowest wettability with a contact angle of 124º (hydrophilic) while HCl-etching is the lowest with 45º (hydrophobic). The results are notable that the ultrasonic cleaning method is able to alter wt% of the oxygen on the EDM-titanium implant surface, whereas the acid etching method can be recommended as a worthy method of the surface finishing for the semi-permanent type of implant.

Published: August 2022

Graphite is a versatile material which is also used in various load bearing applications such as thrust bearings and dies for mechanical pressing such as hot pressing. Natural graphite has anisotropic layered structure which reduces its (compressive) strength in axes which are not parallel to c-axis. To increase strength, isotropy is introduced in graphite structure by breaking down its layers and minimizing grain size. We performed an in-depth characterization of relative aniostropy in graphite using pole figure density mapping. Locally available graphite samples were characterized by XRD and pole figures/3-D orientation distribution function (ODF). SEM and hardness testing were also performed to substantiate the pole density method. Results show that it is possible to characterize (qualitative/quantitative) isotropy or lack thereof in graphite by correlating it with the distribution of crystallinity/pole density mapping of (002) poles and 3D ODF figures.

She underwent repair of the APF with a homograft patch reconstruction of the ascending aorta.
A catheter-based interventional strategy redirects hepatic vein flows after Fontan procedure in left isomerism to treat severe hypoxemia
Authors: Sivakumar Kothandam
Published: August 2022

Pulmonary arteriovenous malformations after the Kawashima procedure causing severe hypoxemia are treated by Fontan surgery that redirects hepatic venous blood to the pulmonary circulation. Alignment of the hepatic venous conduit toward both pulmonary arteries is crucial for their regression. Persistent hypoxemia due to nonregressed malformations in one lung often warrants a repeat surgery to redirect hepatic venous flows. Catheter-based redirection of Fontan flows is not commonly performed as metallic stents and devices may predispose to thrombus formation in the circuit. This report highlights a patient with persistent arteriovenous malformations in the left lung leading to severe disabling hypoxemia that was managed in the catheterization laboratory with an innovative strategy to redirect Fontan flows toward the affected left lung.

Enteropathogenic Escherichia coli (EPEC) is a Gram-negative pathogenic bacterium that causes diarrheal disease, especially in infants and children. Aptamers are short chain oligonucleotides that have high affinity, specificity, and selectivity to their targets, which have potential to be developed as a method for diagnosing pathogens. In this study, aptamer was isolated through the Systematic Evolution of Ligands by Exponential Enrichment (SELEX) method using whole cells bacteria (Bacterial-SELEX) for recognizing pathogenic E. coli EPEC K1.1 which was isolated from children with diarrhea in Indonesia. Ten rounds of bacterial-SELEX procedure were conducted with modification conditions by using Top10, DH5a E. coli cells, Listeria monocytogenes, and Lactobacillus plantarum S34 as counter-selections. The selection process was started with a pool of ssDNA random library consisting of a random base with 40-nucleotides long flanked with fixed primers sequence for aptamer amplification purpose. Short single-stranded DNA amplification was done by symmetric and asymmetric PCR. The highly enriched oligonucleotide pools (pooled 8, 9, and 10) were cloned and the resulting ssDNA aptamers were identified by Sanger DNA sequencing. Finally, twelve aptamers with unique sequences and various secondary structures including G-quadruplex sequence motif within aptamers were obtained as candidates specific aptamer for detection and capturing of EPEC K1.1.

Published: August 2022

Sorghum (Sorghum bicolor (L.) Moench) is a food security crop in sub-Saharan Africa, which requires constant breeding in response to changes in the fragility of agricultural production environments. Hence, understanding and tenacious use of genetic variation in sorghum germplasm is essential for improving the crop to cope with environmental changes. The objective of this study was to determine the levels of diversity and spatial distribution of sorghum on farmers’ fields in major sorghum growing regions in Uganda. A survey involving 180 fields was conducted in three districts, namely Agago and Apac (northern) and Serere (eastern) all in Uganda. Diversity was measured in terms of number of accessions per field, the Shannon-Weaver and Simpson diversity indices. In order to assess spatial distribution of sorghum diversity on the fields, correlation analysis was carried out between diversity and geographical distances between fields. Overall, Agago district had the highest number of accessions per unit area (4.47); while Apac had the lowest (1.62). The spatial distribution of sorghum diversity showed a positive correlation (r = 0.381 for Agago, 0.124 for Apac and 0.081 for Serere), between geographical distances and diversity across the three districts; implying that fields close together share similar sorghum varieties. This can be due to sharing seeds between farmers within a given location. Sorghum diversity was spatially distributed in the fields, with fields close to each other shared most sorghum types. The levels of sorghum diversity on fields were highest in Agago and lowest in Apac district. The existing on-farm sorghum diversity offers the opportunity for improving sorghum through natural breeding against biotic and abiotic stresses.

Tea ranks third after coffee and fish in terms of export value in Uganda’s crop sector. Smallholder productivity and efficiency in Uganda remains a paradox, especially in perennial crops, with past research presenting mixed results on allocative efficiency. The objective of this study was to determine allocative efficiency and its influencing factors among smallholder tea farmers in western-Uganda. A cross-sectional survey dataset was collected from a random sample of 170 tea farmers from Kabale and Kanungu districts in south-western Uganda. The study employed a Stochastic Frontier Approach and the Value of Marginal Product Approach in determining the input elasticities and allocative efficiency levels respectively. Results showed that average allocative efficiency scorers for land, fertiliser, labour and herbicides were 11.17, 1.68, 3.08 and 4.43, respectively; indicating under-utilisation of the inputs. Ordinary Least Squares estimates indicated that allocative efficiency score of fertiliser was positively related to farm size, herbicide type and extension visits. The allocative efficiency score for herbicides was positively influenced by extension access and herbicide type. Similarly, the allocative efficiency score for land was positively influenced by extension access while that of labour was positively influenced by farm size. The results indicate that increasing the scale of tea production in the region is likely to improve productivity and profitability since the average allocative efficiency scores were greater than unity.

Published: August 2022

Uganda’s wetlands, especially in south-western Uganda are increasingly being invaded by cattle herders, particularly during droughts. Such uncontrolled grazing is accelerating wetland degradation. The objective of this study was to assess seasonal forage availability on farms neighbouring Ekigaaga wetland in south-western Uganda, and to determine their optimum stocking for sustainable productivity and ecological stability. The grazed area on each side of the virgin wetland was taken as a block, giving two blocks. In each block, three square metre sampling plots were demarcated along a transect line cutting across farms adjacent to the wetland. Some of these plots were fenced and others were left open to grazing by livestock. Two months after setting up the study, vegetation samples were collected from the fenced and unfenced plots in each block once every month, for a period of six months. Livestock classes and numbers grazing on each block were established and standardised into Tropical Livestock Units (TLU); where one TLU is equivalent to a cow weighing 250 kg. During wet and dry seasons, Cynodon dactylon was the most abundant forage species in the unfenced plots in both blocks. Fencing increased the prevalence of Chloris gayana and Themeda triandra in block 2. Sporobolus pyramidalis was the most abundant weed in both blocks. Fenced and unfenced plots in block 1 had higher grazeable forage yields (488.05 and 399.97 kg ha-1, respectively) than block 2 (432.08 and 371.97 kg ha-1, respectively). The TLU that could be safely grazed on blocks 1 and 2 were 121 and 107, respectively compared to the TLU being grazed on blocks 1 (279) and 2 (381). Therefore, to sustain the productivity and ecological stability of these grazing areas, there is need to control weeds/thickets, improve forage resources by oversowing with quality forages, and to adjust livestock numbers to match with forage quantities available for grazing.

Published: August 2022

Ações de internacionalização são, geralmente, observadas como atividades restritas a uma mobilidade geográfica dos indivíduos. Contudo, em um cenário marcado pela era virtual, sobressai o questionamento se é possível desenvolver a internacionalização a partir da presença de ferramentas digitais. Neste artigo, busca-se analisar se seria possível desenvolver ações de incentivo à internacionalização no ensino médio, mais particularmente no contexto da Rede Federal de Educação Profissional, Científica e Tecnológica do Brasil, ao mesmo tempo em que se investiga de que maneira tais ações poderiam instigar um olhar mais plural sobre o ensino de línguas (tanto no que se refere ao vernáculo quanto às línguas estrangeiras). Para tanto, parte-se da observação do podcast Entrelínguas como uma ação de internacionalização, em que são discutidos os aspectos linguísticos do Português, do Inglês e do Espanhol, considerando-se as questões inerentes ao ensino de línguas em um mundo globalizado, por meio de um diálogo, inclusive, com membros da comunidade internacional. Para subsidiar o estudo, as leituras de Knight (2003; 2004; 2020), Freire (2013), Moita Lopes (2013), dentre outros, foram relevantes para refletir sobre os aspectos da internacionalização, da própria ferramenta do podcast e do ensino de línguas conectados com as demandas comunicativas da contemporaneidade. Procurou-se compreender de que maneira o Entrelínguas responderia aos questionamentos expostos, analisando-se a apropriação educativa de tal produção no cenário da educação profissional. Com um total de 690 reproduções, o Entrelínguas obteve audiência em países diversos e pôde ser visto como uma ponte linguística, um recurso para instigar a internacionalização a partir do ambiente escolar.

Den- tre seus eixos, englobavam-se o aumento do número de profissionais médicos na APS e a melhor distribuição destes pelo território nacional, objetivando a redução das desigualdades em saúde. Após aprovado como projeto de lei, sua implementação, em 2013, passou por desafios e conquistas, atrelando-se a opiniões divergentes sobre seus benefícios à saúde do país. Nesse sentido, a mídia teve papel importante, representando a principal fonte informativa e influenciando diretamente no significado que o programa possuiria. Objetivo: O presente estudo tem como objetivo abordar os pontos da concepção e implementação do PMM, bem como a relação deste com o poder midiático da época, analisando a importância da imprensa para a aceitação da população ao programa. Método: Realizou-se revisão bibliográfica que levantou estudos de mídia e de políticas públicas e compilou-se os resultados conforme as etapas do programa. Conclusão: A partir dos resultados, conclui-se que o processo de concepção foi regulamentado e embasado em indica- dores de saúde fidedignos, assim como sua implementação representou melhorias para a APS exercendo a mídia grande influência para o real significado que o programa obteve para a população.

A importância do futebol de várzea para a população negra de São Paulo (SP)
Authors: Pereira da Silva Roberta
Published: August 2022

O presente artigo apresenta o futebol de várzea da cidade de São Paulo, a partir da história do Negritude Futebol Clube, time criado na década de 1980, construído prioritariamente por homens e mulheres negras, que ocuparam o espaço do recém-inaugurado Conjunto Habitacional nomeado Cohab I. O texto articula o desenvolvimento do futebol de várzea com a organização da juventude negra, que foi capaz de fundar o MNU – Movimento Negro Unificado, e ao mesmo tempo apresentou diversas formas de resistência entre elas os bailes e o futebol, tão importantes para a demarcação da identidade racial e o combate ao racismo. Articulando passado e presente, o texto demonstra como a organização do futebol de várzea pode ser uma possibilidade democratizante frente aos processos de “arenização” do futebol.
A importância da oralidade para os estudos sobre a mulher no futebol baiano: Revisitando memórias
Authors: Vieira Moraes Enny , Pereira Coelho Nivalda
Published: August 2022

Os movimentos em torno da presença das mulheres nos diferentes espaços da sociedade, inclusive no futebol, têm gerado uma série de reflexões relacionadas aos espaços de lutas por reconhecimento e igualdade nos esportes. Desta forma, o presente artigo objetiva abordar aspectos que revelam e destacam a força da metodologia da história oral em estudos anteriores realizados pelas autoras e pelo autor. Estes estudos evidenciaram memórias de mulheres que contestaram uma lógica social preestabelecida dos lugares que elas devem ocupar na sociedade. Assim, revisitou-se aspectos presentes nos relatos de Maria Neide e Risalva, duas praticantes de futebol atuantes na década de 1980 no interior baiano, que assim como muitas mulheres carregam uma trajetória de vida permeada por lutas em busca de reconhecimento e visibilidade social. O uso da história oral possibilita um contato diferenciado com a história, já que utiliza da memória enquanto meio para se chegar aos resultados. Desta forma, conclui-se que os relatos orais, as narrativas e as histórias sobre o passado ajudam a compreender os processos que permeiam a vida das pessoas, das comunidades, das coletividades, permitindo desvelar a complexidade que marca a vida cotidiana e as contradições inerentes às relações de poder incorporadas aos processos sociais vigentes.
Dobras incômodas: Entre corpos gordos e práticas esportivas
Authors: Kessler Cláudia Samuel , Teixeira Silveira Viviane
Published: August 2022

O presente ensaio reflete sobre corpos gordos no esporte moderno, que extrapolam os padrões impostos por um sistema capitalista altamente regulador das subjetividades. Os corpos desejáveis não são apenas produtivos, mas também vendáveis e carregam consigo representações classistas e racializadas. Analisamos as pressões relacionadas à estética e à performance impostas a atletas na atualidade, questionando a ideia de performance ligada ao corpo magro e jovem. Consideramos que o corpo gordo historicamente passou não apenas por julgamentos morais relacionados à forma física, mas também relacionados a status social, sendo até o século XIX considerado símbolo de poder financeiro e político. A partir de casos amplamente divulgados na mídia, parte-se da análise de críticas a três futebolistas da seleção brasileira e, posteriormente, reflete-se sobre modalidades em que a gordura corporal pode ser considerada positiva ou até mesmo aceitável, como no handebol e jiu-jitsu.

Any learning, mediated by a computer and doesn’t require direct interaction between the user and
human instructor in order to run is called Computer Assisted Learning(CAL) .CAL also includes
online courses and supplemental course materials used in colleges, home schooling and distance
learning .Basically , any type of technology that can be used to learn most likely falls beneath the
umbrella of computer assisted learning. CAL makes learning more interactive and engaging. The
advancement in Computer Aided Learning doesn’t mean it will eventually replace the traditional
educational system. But in the situation of a pandemic like this we all are choosing computer assisted
education. It would have been very difficult for us to continue with our educational system in this
pandemic period without the facilities offered by CAL. In this paper, we examine the effect of
computer assisted learning in students’ deep-rooted development. According to the result it indicates
that education technology have long lasting positive effect on a variety of outcome and CAL should
be applied to improve teaching quality. By using CAL it will be possible to eliminate lingual, regional
and ethical biases between teachers and students. Also it can be effective in reducing the rural-urban
education gap.
