PROFESSIONAL PRACTICE OF VISUALLY IMPAIRED EDUCATORS: SCRUTINIZING ACCESSIBILITY
Authors: OLIVEIRA MILENE DA SILVA , PIECZKOWSKI TANIA MARA ZANCANARO
Published: July 2024

ABSTRACT: In a society that is constituted by patterned looks and the logic of normality, visually impaired teachers distance themselves from the standards of body, behavior, and ways of being and doing teaching, which causes strangeness. This article is the result of research that aimed to understand how teachers with visual impairments (blind or with low vision) face the challenges of their professional practice by answering the following research issue: how do visually impaired educators narrate accessibility for professional practice? To do so, narrative interviews were carried out with seven visually impaired educators who work in the Basic Educational System in three Southern Brazilian states. The narratives were organized in thematic groups and examined based on the discourse analysis, supported by Foucauldian references. The study points out that the higher the social barriers imposed, the lower the inclusion possibilities for visually impaired educators in professional practice. It also reveals that inclusion and accessibility have been thought of more for students with disabilities and less for teachers, whose professional insertion is recent and still causes strangeness in school spaces.

Authors: Oliveira E Silva Pedro Ducatti de , Melo Renato Miranda de , Gontijo Cássio Eduardo da Silva , Oliveira Ênio Chaves de
Published: July 2024

ABSTRACT BACKGROUND: Maintaining normal intra-abdominal pressure (IAP) levels must be one major outcome of any ventral hernia repair, avoiding hypertension or abdominal compartment syndrome. AIMS: To evaluate IAP during ventral hernia repair using Lázaro da Silva’s procedure. METHODS: IAP measurements using intravesical pressure were performed during four crucial intraoperative moments. Twenty-eight patients submitted to incisional herniorrhaphy were analyzed. RESULTS: The IAP increased by 0.5 mmHg during the procedure, regardless of the type of prior laparotomy, sex, age, obesity, or hernia width. CONCLUSIONS: Despite the IAP increase observed, Lázaro da Silva’s procedure did not result in intra-abdominal hypertension or abdominal compartment syndrome.
Children between Judicialized Family Ties: A Psychoanalytical Reading on the Parental Alienation
Authors: Dias Júlia , Oliveira Cristiane
Published: July 2024

Abstract This article analyses the dynamics and psychological processes underlying judicialized conflicts that are known as parental alienation, examining three case studies in the light of psychoanalysis. The litigation experienced by the child reflects their embarrassments with the Other in their search for answers to their enigmas and affections, amid guerrilla warfare between those who occupy parental roles. The study pinpoints the pathways required to understand parental alienation: in a socio-historical journey through how parental and marital ties are conceived and recreated; in a passage through the grief that the subjects suffer during family reconstitution; and through a rereading of the phenomenon focused on the uniqueness of the symptom. We are hopeful that it will support a more critical and skilled praxis for those who work in the judiciary.
Filhos entre Laços Familiares Judicializados: Uma Leitura Psicanalítica sobre a Alienação Parental
Authors: Dias Júlia , Oliveira Cristiane
Published: July 2024

Resumo Este artigo analisa dinâmicas e processos psíquicos subjacentes aos conflitos judicializados sob a nomeação de alienação parental, através de três estudos de caso, à luz da psicanálise. O litígio vivenciado pela criança reflete seus embaraços com o Outro na busca por respostas aos seus enigmas e afetos, em meio à guerrilha daqueles que se ocupam das funções parentais. O estudo localiza travessias necessárias à compreensão da alienação parental: das formas sócio-históricas de se conceber e recriar os laços familiares; dos lutos no percurso da recomposição familiar; da releitura do fenômeno visando à singularidade do sintoma. Espera-se contribuir para uma práxis mais crítica e qualificada dos que atuam no Judiciário.
Different Family Arrangements from the Perspective of Pre-teens
Authors: Bastos Lyege de Lima Borges , Dessen Maria Auxiliadora
Published: July 2024

Abstract Economic and social transformations, in the second half of the 20th century, led to changes in concepts of family. This study aimed to investigate the conceptual perspective of 40 children regarding the new configurations of the contemporary family. The children were between 11 and 14 years old, belonged to nuclear and single-parent arrangements, and wrote their answers. The results indicate that the nuclear family continues to be seen as the ‘most perfect’ family. Remarried and single-parent families were classified as ‘not good’, while extended families were perceived with more positive qualifications than negative ones. The results suggest the need to investigate how new family configurations are perceived by children of different age groups and family arrangements.

Authors: Guimarães Maisa Campos , Zanello Valeska
Published: July 2024

Resumo Vivências subjetivas do ciúme são atravessadas por dimensões culturais e de gênero. Na perspectiva dos estudos das masculinidades, objetiva-se uma análise hermenêutica de como homens cisgênero entendem, nomeiam e experienciam esse afeto. Trata-se de pesquisa qualitativa com entrevistas narrativas e análise de conteúdo. Participaram do estudo 8 sujeitos em relacionamentos heteroafetivos com queixas sobre sentir e/ou receber ciúmes. Na categoria “elas ciumentas, eles fortalecidos”, analisa-se o ciúme recebido. Discute-se sobre o ciúme sentido em três categorias: “enciumar-se em meio às questões narcísicas da (im)potência”; “perceber e se esquivar: das ambivalências do afeto ciumento”; “um ciúme disfarçado, mas que exige delas submissão”. Uma leitura gendrada das questões emocionais e narcísicas evidenciaram como experiências ciumentas masculinas se articulam ao dispositivo da eficácia.

Resumo O objetivo deste estudo é apresentar as evidências de validade da Escala de Proteção e Risco de Superendividamento (EPRIS). O instrumento foi construído para avaliar aspectos atitudinais (comportamentais, cognitivos e afetivos) que previnem ou estimulam o superendividamento, considerado um grave problema social. Participaram 444 adultos na modalidade online. A análise Fatorial Exploratória revelou a presença de dois fatores: proteção ao superendividamento (13 itens) e risco de superendividamento (21 itens), com bons níveis de ajuste. A validade de critério mostrou que ambos os fatores diferenciaram grupos quanto ao estresse autopercebido, preocupação financeira, presença/ausência de dívidas e perfil de consumo. Considera-se que a EPRIS tem o potencial de contribuir na formulação de políticas públicas voltadas à abordagem do fenômeno do superendividamento.

Authors: Rozendo Adriano da Silva , Giacomozzi Andréia Isabel , Bousfield Andréa Barbará da Silva
Published: July 2024

Abstract The fires in the Amazon rainforest triggered a series of events with wide media coverage in 2019. This study aimed to analyze the social representations (SR) of the Brazilian people, from the analysis of 679 comments on news articles related to the wildfires, shared on the Facebook pages of the news outlets O Globo, El País Brasil, and BBC News Brasil, newspapers of great impact in Brazil. The Descending Hierarchical Classification of the IRaMuTeQ program produced three main types of SR from the comments, one being empirical, anchored in natural phenomena; a second being geopolitical and a third where controversies emerged in the SR that reflect the political polarization of the country. The debate mainly engages a polarized dispute between Internet users from the left wing and right wing.

Published: July 2024

Abstract This study aimed to identify sociodemographic and behavioral factors associated with the psychological well-being of university students at two distinct moments during the first year of the COVID-19 pandemic. It is an observational study with a cross-sectional design and convenience sampling, involving 2,808 university students who responded to a virtual form. The data were analyzed using descriptive and inferential statistics (Pearson's chi-square test, multiple binomial logistic regression with a significance level of 5%), after conducting normality tests. The results suggest negative impacts of the pandemic on the mental health of university students. A history of previous psychiatric alterations, having children, and having experienced financial difficulties were among the factors that contributed to the maintenance of some dimensions of psychological well-being.

Published: July 2024

ABSTRACT Vacuum is efficient for incorporating solutes of interest into fruits. In this study, the low glycemic and insulinemic index carbohydrate, isomaltulose, was incorporated into mangos slices by immersion with a vacuum pulse (VP). The influences of the combination of pulsed vacuum time at the beginning of the process (5, 10, 15, and 20 min) and vacuum pressure (24 kPa and 48 kPa, absolute pressure) in the incorporation were evaluated with the multidimensional scaling (MDS) statistical technique. Water loss (WL), solid gain (SG), water activity (aw), and color were also studied. The MDS effectively indicated that the vacuum incorporation (VI) with 10 min of VP at 48 kPa provided a product with higher SG (more enriched), WL, lightness, and lower aw and total color difference. Thus, the VI with intermediate conditions resulted in a high incorporated mango with good quality.

ABSTRACT Obtaining introgression lines of saladete-type dwarf tomato plants can provide several advantages in breeding programs. In addition to increasing productivity, the dwarf plant can produce metabolites that are important to resistance to biotic stress. However, there are no saladette-type dwarf tomato introgression lines. The objective of this study was to evaluate the agronomic potential, fruit quality, and secondary metabolites associated with pest resistance for the development saladette-type dwarf tomato introgression lines. The experiment was conducted with 23 treatments, including the UFU MC TOM 1 donor parent, the UFU TOM 5 recurrent parent, the Pizzadoro commercial cultivar (control), 5 populations from the first backcross, and 15 populations from the second backcross. Agronomic and nutraceutical characteristics of fruits and the acylsugar content in the leaflets were evaluated. The genetic dissimilarity was calculated using the generalized Mahalanobis distance (D2). Genetic gain through selection was estimated using the rank sum index and the genotype-ideotype distance index. The selection indices showed the importance of obtaining the second backcross. The populations UFU_13_1, UFU_17_1, UFU_10_1, UFUi_11_3, UFUi_10_3, and UFU_11_2 have the potential to obtain introgression lines as they present good agronomic and fruit quality characteristics and acylsugar content similar to UFU MC TOM 1. The dwarf tomato germplasm obtained has significant genetic variability and a saladette-type genetic background with the potential to develop introgression lines. The cultivar UFU MC TOM 1 is promising and can overcome the wild access Solanum pennellii for breeding programs aimed at pest resistance, increasing productivity, and biofortification of fruits to enhance carotenoids.
Artificial intelligence applied to the classification of greenish seeds and prediction of physiological quality in soybean

Published: July 2024

ABSTRACT The presence of greenish seeds represents an obstacle to the productive potential of soybean cultivation, causing significant impacts on the visual aspect and physiological quality of seeds. Traditionally, seeds are evaluated visually, a method that is subject to subjectivity and human error. This research proposes an innovative approach that integrates image analysis and artificial intelligence to develop a machine learning model capable of distinguishing greenish seeds from yellow ones based on color parameters. This study aims to enhance the accuracy of seed evaluation and expand understanding of the relationship between seed color tone and their physiological quality. The artificial intelligence was trained with 12,000 images captured and processed by the GroundEye® S800D. The methodology employed to train the system involved the use of a decision tree, utilizing the sklearn.tree library from Python. Each seed, after image capture, underwent a standard germination test. The normal seedlings were then reanalyzed using the GroundEye® S800D to determine their vigor through measurements of primary root and hypocotyl sizes. Yellow soybean seeds exhibit superior physiological quality compared to greenish ones, particularly in terms of germination and seedling growth. The hue angle (h) and luminosity (L) proved to be the most responsive criteria in the machine learning model, achieving an accuracy of 89.7%. The hue angle was demonstrated to be a robust predictor, correlating with higher germination rates in seeds with an angle less than 97.5°. The relationship between seed viability and hue angle was supported by a coefficient of determination (R²) of 73%.

Published: July 2024

ABSTRACT Implementing sustainable practices for using agricultural waste is urgent in the face of the challenges of climate change. This study aimed to investigate the application of carboxymethyl cellulose (CMC) derived from soybean hulls as a bioinput in the seed coat of beans. CMC was obtained after bleaching the pulp, alkalizing and etherifying it varying the chloroacetic acid concentration and the reaction time. The properties of CMC were compared to those of soybean hulls and bleached pulp. The CMC with the highest degree of substitution (DS) was chosen as bioinput. In addition to the control treatment, concentrations of 1%, 2%, and 3% CMC were used for coating, and the impact on the physiological quality of seeds was evaluated. CMC proved suitable as a coating agent for seeds, with a DS of 1.56 obtained with 1.2 g chloroacetic acid per gram of bleached pulp during 192 min at 63 °C. The 2% CMC solution proved to be effective, resulting in 93%, 94%, and 43.5% of germinated seeds at 5 days, 8 days, and after accelerated aging, respectively. Seedlings reached 34.2 cm in length and a dry mass of 0.05 g. Our results indicate that soybean hulls can be successfully used in the production of CMC as a coating material, improving the physiological quality of bean seeds and contributing to more sustainable agricultural practices.

Abstract The therapeutic potential of medicinal plants is known as an alternative in treatment of human affections; in effect, the conventional application of these medicinal sources has several limitations like low bioavailability, solubility and stability, which affect its pharmacological efficacy. In recent decades, extraordinary advances have been made in new drug delivery systems using nanocarriers. This work consisted in determining the in vitro antifungal activity of the methanolic extract of Euphorbia tirucalli formulated in polymeric nanoparticles. The antifungal activity was determined by the microdilution method in 96-well microplates, applying nanoparticles loaded with plant extract (NP-Ext) obtained by nanoprecipitation on clinical isolates of Trichophyton rubrum and T. interdigitalis. Regarding the nanoparticles, the lots used did not present significant differences in their physicochemical characteristics, with a size of 91.885 ± 1.621nm, polydispersity index of 0.152 ± 0.025 and Z-potential of -6.047 ± 0.987. The quantification of the extract in the polymeric matrix was determined by infrared spectroscopy (FTIR), where an efficiency and encapsulation percentage of 22.15 ± 0.82 and 2.95 ± 0.11, respectively, were obtained. The in vitro antifungal activity of the crude and formulated extract was obtained calculating the Minimum Inhibitory Concentration (MIC) of each one; a MIC of 125 µg/mL was obtained against T. rubrum and T. interdigitalis with the crude extract, while a MIC value of 55.55 and 0.1 µg/mL was obtained with NP-Ext, respectively, against these same. Conclusions: biological activity is closely linked to the phytochemical profile of the extract; while the improvement of said potential with the NP-Ext with the dosage form was directly related to the physicochemical characteristics of the nanocarrier.

Abstract This work presents the isolation of endophytic fungi from the leaves of Campomanesia adamantium (Cambess.) O. Berg (Myrtaceae), a native species found in Brazil and popularly known as “guabiroba-do-campo”, with abundant distribution in the Brazilian Cerrado. It has been popularly used for its anti-rheumatic, anti-inflammatory, antidiarrheal, blood cholesterol-reducing, urinary antiseptic, and depurative properties. Theese fungi are microorganisms that live inside higher plants, at least for a period of their life cycle, occupying the intercellular spaces of plant tissues such as leaves and stems. These fungi are harmless to the host plant, and their secondary metabolites promote protection, regulate growth, combat bacteria, viruses, and fungi, and promote resistance to abiotic stress, as well as insecticidal effects. Endophytic fungi associated with the leaves of C. adamantium were isolated using the culture medium isolation technique. After growth, the fungi were divided into groups based on morphotypes. Fungal genomic DNA was extracted, and a polymerase chain reaction (PCR) was conducted to amplify the ITS1-5.8S-ITS2 regions of rRNA, and the nucleotide sequences obtained were compared with those available in the GenBank database for molecular identification of the isolates. The phylogenetic tree was constructed using MEGA 11 software. The results showed representatives of the Ascomycota phylum, and it was possible to identify at the genus level 18 fungi of the genera Colletotrichum, Diaporthe, Epicoccum, and Neofusicoccum.

Published: July 2024

Abstract Fungi of the genus Trichoderma spp have been related to the production of hormones or correlated with growth factors, promoting greater efficiency in the use of some nutrients, thus allowing greater availability and absorption by plants. In this context, the objective of this study was to determine the dose of organomineral fertilizer from cupuaçu (Theobroma grandiflorum) residues and the efficiency of Trichoderma harzianum on the initial growth and morphophysiological quality of Mezilaurus itauba seedlings in the northern Amazon. Dose of 50% of the organomineral fertilizer from cupuaçu residues (ORFCup) with Trichoderma harzianum promotes better quality and robustness in Mezilaurus itauba seedlings. The presence of Trichoderma harzianum + 50% ORFCup promotes positive gains in the root biomass of Mezilaurus itauba seedlings. The presence of Trichoderma harzianum promotes an increase in chlorophylls a and b contents in Mezilaurus itauba seedlings. For the production of Mezilaurus itauba seedlings, it is recommended to use Trichoderma harzianum + 50% ORFCup, as it promoted increments in all physiological and morphological indices under the conditions of the present study.

Published: July 2024

Abstract The abundance of spiders in most terrestrial ecosystems makes them good indicators of habitat changes because they are common animals in most terrestrial ecosystems. Due to the importance of knowing the diversity of spiders for conservation efforts and the lack of studies on the spider fauna in urban parks, this work aimed to collect and identify the diversity of spiders present in an isolated fragment of native Atlantic Rainforest vegetation, in an urban area on Diadema, São Paulo. We used pitfall traps over 28 days and active nocturnal search for two hours per night over 6 nights as collection methods. We found a total of 328 individuals, of which 118 adult spiders were assigned to 13 families and 37 morphospecies. Species of families Nemesiidae, Theraphosidae and Deinopidae were found, which are not expected in urban areas. The highest values of abundance were found for the Theridiidae family, with 59 individuals and Araneidae with 28, totaling 73.7% of the total sampled, with Nephilingis cruentata and Parasteatoda tepidariorum being the most abundant morphospecies, with 15 and 11 adult individuals collected, respectively. The richness found in this work was 37 morphospecies and according to the diversity estimators Chao 1 and 2 and Jacknife 1 and 2, it was estimated that the richness of the Diadema Botanical Garden is between 44 and 54 species, a result close to the number of species collected, which indicates that the sampling effort of this work was satisfactory. This work is one of the few inventories of spider fauna in urban fragments of the Atlantic Rainforest and the first study in the Diadema city, one of the cities with the highest population density in the country. It is important to empathize that the results showed a rich and diverse araneofauna when compared with other similar studies, even in an extremely isolated fragment in one of the cities with the highest population density in the state. Public policies specifically aimed at the conservation of these areas should be encouraged so that their preservation is secured.

Published: July 2024

Abstract This study describes and illustrates the biodiversity of macroinvertebrates associated to Sargassum and Dictyota seaweed habitats in the Alcatrazes archipelago, the largest Marine Protected Area (MPA) in the state of São Paulo, southeast Brazil. Assemblages were sampled during the summers of 2018, 2019 and 2020 and winter of 2018 at two sites on the main island. Macroalgae containing the associated fauna were collected at approximately 10 meters deep, with six samples at each site and in each sampling campaign. Sargassum fronds prevailed during summer collections, whilst were absent in the winter campaigns, when Dictyota was the most frequent seaweed. Among invertebrates, 32 species were exclusively found on summer months, associated to Sargassum beds, while 12 species were only registered on winter collection, in association with Dictyota. In total, 91 species were identified, belonging to 60 families, 19 orders, 7 classes and 3 phyla, including Arthropoda (Malacostraca and Pycnogonida), Mollusca (Gastropoda, Bivalvia and Polyplacophora), and Echinodermata (Ophiuroidea and Echinoidea). Among the 91 species found, 73 species are new records for the Alcatrazes archipelago marine area, thus revealing the expressive invertebrate biodiversity living in association with macroalgae beds in that area, which has still been little explored. No significant difference in species diversity was found between the two sites of Alcatrazes. In addition, few specimens of two invasive species were found: Perna perna (Mollusca: Bivalvia) and Ophiothela mirabilis (Echinodermata: Ophiuroidea), which underscores the importance of monitoring different habitats within MPAs to check for possible changes in the fauna over the years. As far as our knowledge, this is the first illustrated inventory of the seaweed-associated macroinvertebrate fauna within the Alcatrazes Archipelago, one of the largest MPAs in the Brazilian coast; besides unravelling its notorious biodiversity, this can act as a reference for future monitoring of local coastal diversity.

Published: July 2024

ABSTRACT Outliers and inliers often arise during sample data acquisition. While outliers represent anomalous observations, inliers are erroneous data points within the main body of the dataset. It was aimed to conduct a systematic literature study (SLS) to survey methods and software employed for outlier and inlier removal, particularly within exploratory data analysis. The study was conducted in three phases: (i) systematic literature mapping (SLM), (ii) snowballing (SB), and (iii) SLR. Initially, 772 scientific studies were identified, subsequently narrowed down to 86 after applying selection criteria. Backward (BSB) and forward (FSB) snowballing further yielded 16 studies, resulting in a final pool of 102 studies for analysis. It was identified three outlier removal techniques (Chebyshev’s inequality, boxplot, and principal component analysis), one inlier removal technique (local Moran’s index), and thirteen commonly used software.

ABSTRACT Water is an essential resource in agriculture, and its efficient use is fundamental to ensuring the sustainability of the sector. The use of more rational and sustainable technologies is an important strategy for optimizing the use of water in agriculture. In view of the above, the aim of this study was to evaluate the effect of different irrigation depths on both chemical and physical variables of melon fruits, and yield, in plants grown with or without hydrogel application. The experiment was conducted in a randomized block design with ten treatments and four blocks. The treatments were arranged in a 5 × 2 factorial scheme, referring to five irrigation depths (50, 75, 100, 125, and 150% of crop evapotranspiration - ETc), and with or without hydrogel application (4 g L-1). The irrigation system used was drip irrigation. Irrigation depths positively influenced the variables evaluated, with the highest yield (39,075.69 kg ha-1) obtained with the highest water depth of 394 mm (150% ETc), while the use of hydrogel reduced the internal cavity of the fruit. The fruit physical characteristics (pulp thickness and internal cavity) showed positive linear increments within the interval of irrigation depth evaluated. Fruit electrical conductivity showed a linear decrease as the irrigation depths increased, while the pH was described by a quadratic polynomial equation. The use of hydrogel was not enough to mitigate the negative effects of deficit irrigation. However, the increase in irrigation depths improved the quality and yield of melon fruit.

Published: July 2024

ABSTRACT Despite highly efficient, the main limitation of using drip irrigation for fertigation with nitrogen (N) fertilizers is the sensitivity of emitters to clogging by contaminants. The objective in this study was to assess the effect of different sources of N fertilizer and different operation times on water distribution uniformity and emitter clogging using a localized surface drip irrigation system. A randomized block experimental design with three replicates was used, in a 5 × 6 factorial arrangement consisting of five N sources (potassium nitrate, ammonium sulfate, calcium nitrate, ammonium nitrate, and urea) and six operation times (100, 200, 300, 400, 500, and 600 hours). The same nitrogen (N) rate applied in all treatments was equivalent to 100 kg ha-1. The drip tubing used had a nominal flow of 2 L h-1, nominal diameter of 16 mm, internal diameter of 13 mm, operating pressure of 100 to 350 kPa, and spacing between emitters of 0.7 m. The variables evaluated were: statistical uniformity coefficient, absolute uniformity coefficient, and degree of clogging. The best absolute and statistical uniformity coefficients were found when using urea and ammonium nitrate for fertigation, mainly at the longest operation times, which presented the best water application uniformity (>91.72%).

Published: July 2024

Resumo: O objetivo deste estudo é apresentar razões para se arquivar sites por meio de casos de uso de arquivos da web e de arquivamento da web. Caracteriza-se como uma pesquisa exploratória que adota o método bibliográfico e documental a partir de uma revisão de literatura sobre o assunto. Aplicou-se a análise de conteúdo da revisão de produções científicas atuais nacionais e internacionais da Ciência da Informação, assim como, de sites oficiais, políticas e diretrizes de arquivos da web no mundo. Concluiu-se que há motivações mais abrangentes para que instituições desenvolvam os arquivos da web, incluindo-se, dentre tais motivações, a urgência de se preservar conteúdos web, devido ao risco de perda desse conteúdo, salvaguardando, dessa maneira, o patrimônio digital produzido por nações, e os inúmeros casos de uso dos arquivos da web. Complementarmente, no entanto, reconhece-se, efetivamente, a questão da legislação, que pode obrigar e estimular essas iniciativas, conferindo o direito e a proteção desses conteúdos às instituições, delegando-lhes as funções de captura, abrigo e arquivamento dos materiais web, seja no papel de um depositário legal, visando: preservação da memória social; ou, por conformidade normativa, e apoio em processos judiciais. Entender os insights providos pelos arquivos da web justificam, em certa medida, os futuros investimentos financeiros, políticos, científicos, etc., na preservação digital e arquivamento da web, sobretudo, em países que não detêm um arquivo da web nacional, como no caso do Brasil.

Published: July 2024

Resumo: A memória institucional objetiva assegurar a preservação e a transmissão da história, identidade e conhecimentos acumulados ao longo do tempo por uma instituição, através daquilo que é produzido pelos indivíduos que a instituem e de suas relações com a sociedade. No contexto das universidades, engloba um conjunto diversificado de materiais, representativos dessa produção, evidenciando as interações socioculturais e científicas que moldaram o percurso da instituição ao longo do tempo. Nesse sentido, entende-se que abrange não apenas a documentação oficial e acadêmica, mas também pensamentos e ideias retratados nos acervos pessoais de personalidades que ajudaram a construir essa memória, e que estão custodiados em bibliotecas nas universidades. Esta pesquisa surge da percepção de que alguns acervos pessoais, doados à Universidade Federal do Ceará, carecem de estudos e tratamento técnico, tanto em relação à sua representatividade social e preservação, quanto à gestão e ao acesso. O objetivo deste estudo é, portanto, promover uma discussão acerca das possíveis interseções entre memória institucional, representação da informação e gestão do conhecimento, destacando, de forma breve, dois acervos que são partes dessa memória. Em conclusão, se reconhece que são componentes integrantes do patrimônio documental acadêmico e desempenham um papel importante na contextualização da história social, cultural e científica da universidade.

ABSTRACT Objective: To explore the effects of electric stimulation and biofeedback therapy in patients with postpartum pelvic organ prolapse and to identify factors that can affect therapeutic efficacy outcomes. Method: This retrospective study analysed clinical data about patients with postpartum pelvic organ prolapse. A total of 328 women with pelvic organ prolapse at 6 weeks postpartum were recruited from one tertiary hospitals in Sichuan province in China, between March 2019 and March 2022. The prognostic factors of therapeutic efficacy were analysed using logistic regression and decision tree model. Results: Overall, 259 women showed clinical benefits from the treatment. The logistic regression model showed that parity, pelvic floor muscle training at home, and the pelvic organ prolapse quantitation stage before treatment were independent prognostic factors. The decision tree model showed that the pelvic organ prolapse quantitation stage before treatment was the main prognostic factor, followed by parity. There was no significant difference in the area under the receiver operating characteristic curve between the two models. Conclusion: Parity, pelvic floor muscle training at home, and the pelvic organ prolapse quantitation stage before treatment were important prognostic factors of electric stimulation and biofeedback therapy on postpartum pelvic organ prolapse.

Resumo No presente artigo revisitamos o Código das Águas da República, preparado por Alfredo Valladão em 1907, promulgado pelo Congresso Nacional, Decreto nº 24.643, somente a 10 de julho de 1934. Um dos principais marcos da regulamentação do setor no Brasil, não sem intenso dissentimento, engendrou a crescente presença do Estado a partir dos anos 1930, fundamental para o desenvolvimento do setor. Nos importa retratar o espírito que animou o seu autor e seus resultados na Primeira República (1889-1930), quando o monopólio estrangeiro se inseriu e passou a controlar por quase 80 anos boa parte do setor de serviços públicos, assim como algumas das consequências que perduraram ao longo do século XX. Esse domínio foi fruto da expansão do capitalismo financeiro dos países centrais e a ordenação criada no Brasil pode ter sido a reação possível. As principais fontes e documentos foram o Código das Águas da República, edição original de 1907, e a reedição do DNAEE em 1980, o Diário da Câmara dos Deputados, entre 1907 e 1915, para tentar retraçar as causas de seu longo embaraço, o Jornal do Commercio, entre 1901 e 1932 (ambos disponíveis na internet), além de obras e autores que fizeram comentários e censuras ao Código. O panorama dos serviços públicos vem mudando novamente nos últimos 40 anos, com setores estratégicos para o desenvolvimento do país destinados, mais uma vez, ao capital privado e estrangeiro, após o período de forte presença do Estado. Torna-se premente então suscitar reflexões sobre o tema.
Do trabalho de servir ao trabalho remunerado: definindo o serviço doméstico a partir da história (Brasil, Rio de Janeiro, c. 1850 a 1950)
Authors: Souza Flavia Fernandes de
Published: July 2024

Resumo Este artigo tem como objetivo refletir sobre o conceito de serviço doméstico a partir de uma perspectiva histórica, tendo como referência a história do trabalho realizado nos domicílios urbanos por trabalhadoras e trabalhadores escravizados e livres, especialmente na cidade do Rio de Janeiro, então capital brasileira, entre aproximadamente 1850 e 1950. Para isso, o texto problematiza, a partir de diversas fontes documentais e estudos sobre o tema, noções que costumam estar associadas às definições do trabalho doméstico, em sua face de prestação de serviços, como as que compreendem a natureza das atividades laborais, os espaços em que eram realizadas e o tipo de trabalhadores envolvidos. A hipótese defendida é a da existência histórica de uma grande complexidade nas relações de trabalho estabelecidas no âmbito da domesticidade, sobretudo no que se refere à integração de determinantes de classe, gênero e raça, bem como às características da organização da reprodução social em contextos como os da passagem do trabalho escravo/servil ao trabalho livre/remunerado na constituição do capitalismo no Brasil
“Uma expedição commercial Yankee vem estudar a carnahuba”: S.C. Johnson & Son., trabalho de campo e exploração científica e comercial da cera de carnaúba no Brasil (1935)
Authors: Moreira Paulo Italo
Published: July 2024

Resumo Este trabalho examina a Expedição Carnaúba, uma viagem de prospecção comercial e científica realizada pela companhia norte-americana S.C. Johnson & Son. no Brasil em 1935. A expedição teve como proposta investigar as maiores áreas de ocorrência da palmeira carnaúba (Copernicia cerifera Mart.), árvore nativa do semiárido brasileiro, como pontapé para exploração técnico-científica de uma matéria-prima produzida por esse vegetal: a cera de carnaúba. Por meio da análise do relatório da expedição e de documentos oficiais emitidos pelo governo brasileiro à época, verifica-se que a realização da expedição se tornou possível mediante estreita articulação entre a empresa e o governo brasileiro, permeada por interesses políticos, científicos e econômicos, numa conjuntura de cuidadosa fiscalização e controle das atividades de estrangeiros no país por meio do Conselho de Fiscalização das Expedições Artísticas e Científicas no Brasil (CFE). Lançar luz sobre a Expedição Carnaúba e o seu esforço para produção da cera de carnaúba em larga escala decorrentes da crescente aproximação entre ciência e indústria é evidenciar mais um episódio da história da exploração dos recursos naturais do Brasil na primeira metade do século XX.

Abstract Creutzfeldt-Jakob disease is a rare condition caused by prions. Although the infectious form of the disease is the most well-known, the most common form is the so-called sporadic type, where the transformation of cytoplasmic proteins from glial cells into prions occurs. The disease is characterized by rapidly progressive dementia whose diagnosis can be made with great accuracy based on clinical signs, typical changes on magnetic resonance imaging and real-time quaking-induced conversion (Rt-QuIC) testing in cerebrospinal fluid. We report a case of the disease without cognitive disorders in the initial phase, but with other common clinical signs including behavioral abnormalities, ataxia, extrapyramidal features, and myoclonus; typical changes on magnetic resonance imaging of the skull (signal alterations affecting parietal and temporal lobes areas) and strongly positive Rt-QuIC test. This case report can serve to alert other health professionals on recognizing the disease and contribute to a more accurate diagnosis in similar cases.

Resumo Objetivos estimar a prevalência de depressão em pessoas idosas do Brasil e os fatores associados, e descrever características do uso de serviços de saúde e tratamentos de saúde dispensados aos idosos com depressão. Método Estudo transversal, analítico, com 22.728 pessoas idosas participantes da Pesquisa Nacional de Saúde (PNS), selecionadas aleatoriamente no Brasil, no período de agosto de 2019 a março de 2020. O desfecho foi o autorrelato de depressão e as exposições foram as variáveis sociodemográficas e um escore de rede social. Foram empregadas análises descritivas e múltiplas por meio de regressão logística. Resultados A prevalência de depressão autorrelatada pelas pessoas idosas foi de 11,8% (IC95%: 11,1-12,57). Observou-se que 71,6% (IC95%: 67,9-75,0) da população idosa com depressão faz apenas tratamento medicamentoso. Houve maior chance de depressão entre idosas (OR=2,46; IC95%: 2,06-2,94), de 60 a 69 anos (OR=1,67; IC95%: 1,31-2,14); de cor de pele branca (OR=2,95; IC95%: 1,62-5,39), moradores da região Sul (OR=3,01; IC95%: 2,27-4,00) e com multimorbidade (OR=1,79; IC95%: 1,49-2,14). Conclusão A depressão apresentou-se com frequência considerável entre pessoas idosas, especialmente entre mulheres. Há necessidade de incentivo a adoção de medidas não farmacológicas para tratamento da doença, tais como, uso de práticas integrativas e complementares atividades físicas, mudanças no estilo de vida e fomento a atividades sociais.

Resumo Objetivo Verificar o impacto da participação de programas de exercícios físicos em pessoas idosas com doença de Alzheimer (DA) e os fatores que comprometem a sua prática. Método Trata-se de uma revisão sistemática nas bases de dados United States National Library of Medicine (PubMed), Web of Science, Scopus, Biblioteca Scientific Electronic Library Online (SciELO); LILACS e Embase, a partir de 2014. Utilizaram-se as diretrizes do PRISMA – 2020 e a análise de risco de viés com o apoio da ferramenta Cochrane (RoB2). Resultados Foram incluídos onze estudos para análise qualitativa. O comprometimento da memória episódica ocasiona um declínio na DA e envolve uma complexidade de processos cognitivos contendo múltiplos aspectos do sistema neural Conclusão A depressão, a ansiedade e a dificuldade de compreensão são os principais fatores que comprometem a participação da pessoa idosa com Alzheimer aos exercícios com o propósito de estímulo físico, e são os principais preditores que dificultam o desenvolvimento perceptivo-motor. Os protocolos com exercícios combinados parecem favorecer melhor a função executiva no paciente com DA. A conscientização do exercício físico é fundamental desde o início dos tratamentos, com a sugestão de se priorizar melhorias na atenção das pessoas idosas com DA. As particularidades da relação entre as atividades da vida diária e a capacidade funcional do paciente com Alzheimer ainda correspondem a uma lacuna a ser explorada, assim como a prescrição de exercícios específicos que considerem tanto o grau de atenção quanto o nível da doença.

Published: July 2024

RESUMO O artigo analisa o oferecimento de licenciaturas no estado de São Paulo após a ampliação de campi do Instituto Federal de São Paulo (IFSP). Tem como objetivo examinar o crescimento dos cursos destinados à formação de professores no modelo de IF e o seu alcance nesse estado em comparação às demais instituições de educação superior (IES). O texto é resultado de estudo que analisou dados estatísticos, documentos e entrevistas semiestruturadas. As entrevistas foram realizadas com gestores que participaram da elaboração do projeto de desenvolvimento dos Institutos Federais (IFs) em âmbito governamental. Verificou-se a concentração de cursos de licenciatura nas regiões metropolitanas, sobretudo via IES privadas, mas também se revelou a presença mais notável na atuação das instituições públicas em regiões do interior. Engloba, ainda, um balanço da avaliação de cursos de licenciatura ministrados em São Paulo, tomando-se como base o Conceito Preliminar de Curso (CPC), indicador do Sistema Nacional de Avaliação da Educação Superior (Sinaes). A abertura de novas licenciaturas do IFSP ocorreu sobretudo no interior paulista, o que permitiu a expansão da formação docente com padrão de qualidade referenciada em algumas regiões antes carentes de instituições públicas. Por fim, constatou-se destaque da instituição na oferta, principalmente, de licenciaturas em Física, Química e Matemática.
Influências da política educacional no sindicalismo docente brasileiro
Authors: Vaz Marta Rosani Taras , Masson Gisele
Published: July 2024

RESUMO O objetivo deste artigo é apresentar uma análise das relações entre o sindicalismo docente e a política educacional no Brasil, desvelando as determinações dessa relação na luta pela garantia de uma remuneração justa. Resultado de uma pesquisa mais ampla de Doutorado sobre sindicalismo docente, este texto se fundamenta nos pressupostos teóricos e metodológicos do marxismo e se caracteriza por ser um estudo bibliográfico e documental. Com base no estudo realizado, é possível indicar que a luta econômica sindical dos professores é mediada e influenciada pela política educacional, sobretudo aquelas que determinam o financiamento (como o Fundo de Manutenção e Desenvolvimento da Educação Básica e de Valorização dos Profissionais da Educação - Fundeb) e a valorização dos profissionais do magistério (como o Piso Salarial Profissional Nacional - PSPN), condicionando o caráter das lutas e o conteúdo das pautas reivindicativas. Se, por um lado, a aproximação do sindicalismo docente com as políticas educacionais representa um avanço, no sentido de uma carreira docente legislada; por outro lado, contraditoriamente, condiciona o sindicalismo ao ritmo das políticas do Estado.
