Authors: Silva Fernanda Oliveira da , Velasco Giuliana Del Nero , Longo Mariana Hortelani Carneseca , Amaral Raquel Dias de Aguiar Moraes
Published: April 2023

As árvores exercem papel fundamental na qualidade ambiental e seus benefícios são indiscutíveis para a vida nas cidades. A expansão e crescimento urbanos sem fundamentação no planejamento arbóreo geram prejuízos na provisão desses serviços ambientais. O presente estudo teve como objetivo conhecer a composição florística e caracterizar a heterogeneidade e similaridade entre os indivíduos arbóreos de diferentes bairros do município de São Paulo. Os resultados indicaram alta similaridade de espécies entre bairros, conforme índice de Jaccard, e alta diversidade de espécies segundo índice de Shannon Weaver (H’) para os sete bairros avaliados na cidade de São Paulo, SP. Analisar a diversidade arbórea na cidade e planejar novos plantios atentando-se para a manutenção equilibrada de árvores da mesma espécie, gênero e família é primordial quando se almeja um planejamento arbóreo coerente e que considera a restauração dos ecossistemas degradados.

Authors: Paula Franklin Roberto Ferreira de , Imbronito Maria Isabel
Published: April 2023

This article aims to explore the green areas of the Encosta Norte Housing Complex, located in the Itaim Paulista district, East Zone 2 of the city of São Paulo, in order to figure out how the local community perceives those spaces from the identification of existing weaknesses and potentialities, as well as to recall the indications of wishes for improvements in its extensions. In addition to the technical field visits to the territory, some activities with the residents and other local agents were proposed as a methodology for the construction of this cartography. The methodological instrument applied to the population was the walkthrough analysis, or route-interview, that took place on 09/17/2022, aiming to record, through notes, audio recordings and photographs, the perceptions of the community about the inhabited place. The achieved results demonstrate that the participants of the activity relate to the place through affective memories of how the territory used to be, just before the urbanization process that began to be implemented in the mid-1980s. Some problems such as lack of maintenance of open spaces and springs and water courses were also pointed out as weaknesses. The researchers, proponents of the dynamics, reinforce the potential of transforming these available public areas belonging to CDHU as a strategy for the requalification of the area and for the improvement of the quality of life of local population.

Authors: ÖZKAR Şerife
Published: April 2023

In this study, a production inventory model with phase type service times where customers join the system occur according to a Markovian arrival process is discussed. When the inventory level is positive, if an arriving customer finds the server idle gets into service immediately. Served customer leaves the system and the on-hand inventory is decreased one unit of item at service completion epoch. Otherwise, the customer enters into a waiting space (queue) of infinite capacity and waits for get served. The production facility produces items according to an (s,S) policy. The production is switched on when the inventory level depletes to s and the production remains on until the inventory level reaches to the maximum level S. Once the inventory level becomes S, the production process is switched off. Applying the matrix-geometric method, we carry out the steady-state analysis of the production inventory model and perform a few illustrative numerical examples includes the effect of parameters on the system performance measures and an optimization study for the inventory policy.
Lakes ABPS Protocol - Optimized protocol for the extraction of fish DNA from freshwater sediments (Thomson-Laing et al., 2022) v1
Authors: Thomson-Laing Georgia
Published: April 2023

DNA was extracted from lake sediment samples by an alkaline lysis method with ethanol precipitation adapted from method described by Kuwae et al. (2020); Sakata et al. (2020b); Sakata et al. (2020a). In a comparison of multiple sedDNA extraction methods, the ABPS (Alkaline buffer - power soil) protocol yielded the highest concentrations of target genets across a range of lake sediments. This protocol was further optimized (65C incubation temperature, pooling of multiple PowerSoil extractions) to overcome technical challenges related to co-precipitation of organic content in lake-surface sediments. The optimized ABPS protocol is called the "Lakes ABPS protocol" This protocol has proven to be successful at detecting fish sedDNA from surface sediments in multiple systems for multiple species.

Authors: Derman Mustafa
Published: April 2023

The importance of biodiversity is one of the most critical issues today, and intense efforts are being made to protect and maintain biodiversity. In this study, biodiversity, which is related to many disciplines, was evaluated in terms of education. A bibliometric analysis was used. The bibliometric method is widely used to reveal the relationship between scientific studies, the effect of the studies, and the effect of the researchers and journals in a particular field. Research findings showed that many articles have been published on biodiversity recently. In education, out-of-school learning activities are used more widely today. Moreover, the USA, China, and Germany are among the countries that publish more articles about biodiversity. Based on the research findings, it was determined that combining the formal education process with out-of-school activities will help students exhibit positive behavior about the environment and biodiversity. Considering the trend in recent years, studies related to climate change, ecosystem service, sustainability, and citizen science can be carried out.

Published: April 2023

Precast concrete has been used for many decades with optimized consumption of concrete and reinforcement. The use of monolithic reinforced concrete in the Russian Federation cannot be called balanced in terms of its material consumption. One of the design ideas for creating lightweight slab reinforced concrete structures in monolithic construction is the BubbleDeck technology. Spherical bushings are located in places of the least stresses in the structure, which leads to a significant reduction in the own weight. The article presents the results of assessing the strength, stiffness and crack resistance of a reduced model of a reinforced concrete slab in comparison with similar parameters of a solid section slab.
Improving the thermal protection characteristics of building enclosing structures of the Samara Academic Drama Theater building
Authors: Saparev Mikhail Y. , Vytchikov Yuri S. , Chulkov Aleksandr A. , Dyadin Andrey A.
Published: April 2023

Preservation of the architectural appearance of buildings of historical and cultural heritage is a prerequisite for their energy modernization when performing major repairs or reconstruction. In this regard, it is not possible to use facade systems to reduce heat losses by external walls. The use of internal insulation, as construction practice has shown, quite often led to a violation of the humidity regime of enclosing structures and, as a result, to the formation of dark spots and mold fungi on the internal surfaces. To prevent moisture accumulation in enclosing structures, with internal insulation, only thermal insulation materials with a low coefficient of vapor permeability should be used. The article presents the results of a thermal imaging survey of the facades of the Samara Academic Drama Theater building, which indicate increased heat loss in the basement of the building and the exterior walls made of silicate bricks after reconstruction in 1967. In order to meet modern regulatory requirements for the thermal protection of buildings of historical and cultural heritage, it was proposed to additionally insulate the exterior walls from the inside above the zero mark with foam glass, as well as warm plaster in the basement and basement of the building. Solutions are proposed for the replacement of window structures, entrance doors, coverings and ceilings to increase the energy efficiency of the operated building. When performing the thermophysical calculation of the above-listed enclosing structures, the authors methodology for estimating the plane of possible condensation was applied, which allows for a higher probability of assessing moisture accumulation in them.

Retrospective Study of the Efficacy and Safety of Laser
and Oral Combination Therapy for Non-responders to
Neodymium-doped Yttrium Aluminum Garnet Laser:
A Review of 20 Patients with Onychomycosis
Authors: Lee Sang-Doo , Shin Min Kyung
Published: April 2023

Background: Oral antifungal drugs are the primary treatment for onychomycosis. However, there are few studies on the effectiveness and safety of oral combination therapy after laser treatment.
Objective: We sought to contrast the efficacy and safety of laser and oral combination therapy with that of oral monotherapy for non-responders to laser treatment.
Methods: We retrospectively evaluated the medical charts and photographs of 20 patients who received four sessions of Nd:YAG laser. Among these patients, 11 were "laser non-responders" and 9 were "laser partial responders". Afterward, 10 patients received oral drugs in addition to laser treatment (combination therapy) and the other 10 were completely altered to oral drugs, with no laser treatment (oral monotherapy). Clinical evaluation was conducted at baseline and 3 months after treatment. Recurrence was evaluated 3 months after the final evaluation.
Results: Clinical evaluation revealed that combining or switching to oral antifungal drugs was substantially effective in the laser non-responder group (Z = -2.481, p = 0.013). Combination therapy was more effective than oral monotherapy (Z = -1.324, p = 0.247). Furthermore, positive baseline mycological results demonstrated a higher
possibility of laser monotherapy failure (χ2 = -5.089, p = 0.024). There were two cases of recurrence in the oral monotherapy group and no adverse effect was discovered in any patient.
Conclusion: This study highlighted that the combination of oral drugs with laser therapy could be beneficial
regarding efficacy, recurrence, and safety in the treatment of patients who are refractory to laser therapy.
A Case of Oral Candidiasis Treated with
Fluconazole (Diflucan®) Mouthrinse
Authors: Yoo Dong-Wha , Park Kyung-Deok , Kwon Hyeok-Jin , Seo Jeong-Wan , Yoon Jung-Ho , Kim Ki-Ho
Published: April 2023

Oral candidiasis, a common fungal infection in humans, is characterized by the overgrowth of Candida species in the superficial oral epithelial mucosa. The condition is associated with multiple risk factors, including impaired salivary gland function, oral mucosal damage, and long-term antibiotic or corticosteroid use. Several treatment
options are available; nystatin and amphotericin B are the most widely used local medications. Recently, fluconazole has emerged as the preferred systemic treatment. We report a case of oral candidiasis in an 83-year-old male diagnosed with bullous pemphigoid in 2017 and previously administered methylprednisolone. He developed oral
candidiasis a few months before presentation and was treated with 10 mL nystatin suspension three times daily; unfortunately, the disease was recalcitrant to this treatment and his symptoms showed no improvement over two months. We discontinued nystatin in favor of fluconazole syrup (Diflucan®) administered by rinsing, then swallowing, 5 mL syrup once daily. The lesion improved after one month of treatment. This case demonstrates the efficacy of fluconazole as a primary treatment for oral candidiasis. The act of rinsing the mouth with syrup exposes the oral
mucosa to drug, potentially producing a better treatment response than taking the syrup orally without rinsing.

Published: April 2023

Severe pneumonia is a condition with a high risk of death and mandatory hospitalization in the intensive care unit. The incidence of severe pneumonia has increased dramatically during the pandemic of new coronavirus infection. Timely diagnosis and early initiation of adequate treatment of severe pneumonia are crucial for improving survival of critically ill patients.

The aim of this review was to analyze published scientific research on molecular markers that allow to objectively assess the severity of pneumonia and to determine treatment tactics based on the predicted outcome upon admission to the hospital. A systematic search was conducted in the electronic databases PubMed, Medline, Web of Science for the period 2019 - 2022.

Conclusion. The review focuses on the prognostic role of a number of markers of immune response, vascular transformation, as well as angiotensin II and angiotensin converting enzyme-2. Further prospective studies of potential predictors of severe pneumonia will enable using marker molecules in a comprehensive clinical and laboratory diagnosis for early prediction of the hospitalized patient’s condition and expected outcome.

Published: April 2023

Birt - Hogg - Dubd (BHD) disorder is a rare inherited autosomal dominant disorder caused by germline mutations in the tumor suppressor gene FLCN, which encodes the protein folliculin. BHD disorder is characterized by benign skin hamartomas, kidney cancer, pulmonary cysts, and spontaneous pneumothorax. Currently, more than 600 cases of this disease have been described worldwide. Diagnosis of BHD disorder is based on clinical manifestations, family history, and genetic testing. We describe two patients (43 and 51 years old) who presented with a history of longstanding dyspnea and spontaneous pneumothorax. Based on the radiological characteristics and skin lesions, the patients were referred for genetic testing to confirm the diagnosis of BHD disorder.

Aim. To study the current management of adult patients with BCD disorder. Timely diagnosis of BHD disorder has important preventive value because patients with this disease are at much higher risk for kidney cancer.

Conclusion. The presented clinical cases demonstrate typical manifestations of BCD disorder with predominant involvement of the lungs and skin. The final diagnosis is confirmed by genetic testing of the coding sequence of the FLCN gene by direct automated sequencing. To date, there are no specific therapies for BCD disorder and treatment of the respiratory manifestations is limited to prevention and treatment of pneumothorax.

Authors: Masroor Safina , Nagaveni N.B  , Poornima P
Published: April 2023

Sex determination is an important aspect in identification of individuals especially in cases of identifying victims of mass disasters, organised crimes etc. Odontometry is the measurement and study of tooth size. Cranial anthropometry is the measurement of skull dimensions and is considered to be a versatile technique in the investigation of the craniofacial skeleton because of its validity and practicality.

To assess tooth crown area of the deciduous molar teeth, to assess head size, to evaluate the extent of sexual dimorphism using head and dental dimension

: This study was done in 150 boys and 150 girls. Maxillary and mandibular arch impressions were made, casts were made with dental stone. A vernier calliper was used for obtaining the measurements. Mesiodistal width and buccolingual width of all the molars were measured in millimetres, tooth crown area (TCA) was calculated. Head dimensions were measured using Martin spreading calliper, Cephalic Index (CI) was calculated. Statistical analysis was done using unpaired “t” test, and logistic regression analysis was performed.

: The highest tooth crown area was shown by mandibular left second deciduous molar for both boys and girls (p<0.05). Boys showed higher cephalic index compared to girls (p<0.05). The highest percent dimorphism was obtained for maxillary left first deciduous molar.

Tooth crown area and head size can serve as a valuable aid for sex determination in pediatric population.

: To compare the efficacy of active oxygen - containing mouthwash (BlueM) with chlorhexidine mouthwash (Hexidine) and its effect on plaque, calculus, and gingival inflammation.

A Double blind parallel study was done on 20 systemically healthy patients with the presence of generalized chronic gingivitis in the age group of 20-45 years. Each subject will rinse their mouth with the mouthrinse assigned to them, or twice daily for one minute in the morning and before going to bed. They will be instructed to swish it properly around the mouth and avoid its ingestion.

Descriptive statistics was performed by calculating mean and standard deviation for the continuous variables. Intergroup and intragroup comparisonbetween chlorhexidine and Blue M at baseline (To) and at the end of 3 weeks (T1) showing no statistical differences between the two groups.

Blue M can be used as a safe alternative to chlorhexidine in reducing the microbial load. But when compared to each other there wasn't a significant change between them. Chlorhexidine has the edge in being very cheaper compared to Blue M. Further studies are required with conclusive evidence to be able to determine whether oxygen enriched mouthwashes can replace chlorhexidine in the future.

Authors: Badhan Tejal , Shah Kanchan M , Landge Jayant S , Sindhuja K
Published: April 2023

Ossifying fibroma (OF) is classified as, and behaves like, a benign bone neoplasm. It is often considered to be a type of fibro-osseous lesion (FOL). It can affect both mandible and the maxilla, particularly the mandible. This bone tumour consists of highly cellular, fibrous tissue that contains varied amounts of bone or cementum resembling calcified tissue. Present case is an unusual report of ossifying fibroma involving the left side of maxilla in a 13-year old male patient, who presented to the department with a painless hard swelling. The lesion was treated by surgical enucleation and curettage.

Surgical enucleation and curettage was performed.

: Healing was uneventful, patient has been kept on a regular follow-up regimen.

The case report and treatment of an unusual case of Ossifying fibroma in the maxilla of a paediatric patient has been described. Based on our experience, we suggest that proper correlation of the clinical, radiological and histological features is necessary to establish a definitive diagnosis, as well as for proper surgical intervention. As reported in the literature, the rate of recurrence is not very high, but long term periodic follow-up is warranted.
Managing leukoplakia with diode laser: A report of two cases
Authors: Bacholkar Smita Ajit , Navalkar Amita
Published: April 2023

Oral leukoplakia is the most common precancerous lesion of the oral mucosa. WHO defined it as a lesion which has a white patch or plaque on the oral mucosa that cannot be removed by scraping and cannot be classified clinically or microscopically as another disease process. Management of oral leukoplakia should begin with elimination of predisposing habit. There are currently different approaches in the management of Leukoplakia such as scalpel surgery, systemic carotenoids and antioxidants, electro cauterization, cryotherapy and Lasers. Even though on-surgical options are preferred choice of treatment, it takes time to achieve complete regression of lesion and sometimes may not achieve complete resolution. On the other hand, conventional surgical techniques are invasive and cause trauma to the patient. Excision of precancerous oral lesions using LASER offers comparative advantages over traditional scalpel excision. Laser is an acronym for Light Amplification by stimulated emission of radiation. It is surgical technique which excises the targeted tissue using emission of a monochromatic light of specific wavelength. Because of this property, laser excision of the tissue results in complete bloodless field of surgery, reduced chances of post-surgical inflammation and infections and hence better treatment compliance of the patients towards the surgery. This is one of the important goals for management of oral potentially malignant disorders. We present two case reports of homogeneous leukoplakia treated using diode lasers of wavelength 810nm with follow-up. Both cases did not report any post-operative discomfort or inflammation. The aim of this case report is to highlight the importance of laser excision with minimal complications and better treatment outcomes.

Published: April 2023

Skeletal class III malocclusion in adult patients are generally managed by orthognathic surgery. However, the prognosis is poor when the patient refuses surgical line of treatment. In such cases orthodontic camouflage through dentoalveolar compensation may be attempted. Presently, with the advent of stationary anchorage, en mass distalization appears to be a common choice. This article demonstrates an en mass distalization carried out in the upper and lower arches in a class III skeletal case, refusing surgery. After initial levelling and alignment, TADs (temporary anchorage devices) were placed bilaterally mesial to the first molars in upper and lower arches. After a month, distalization was initiated with 300 gms force applied per side using elastomeric chain. At the end of the treatment, the anterior cross bite and crowding was resolved and the patients profile improved. Thus, en masse distalization with TADs appears be a good choice in class III skeletal cases refusing surgery. It is minimally invasive and cost effective.

The aim of research was to study the distribution of mast cell populations in the lungs and spleen depending on their expression of proteases in normal conditions and different periods of simulated hypoxic hypoxia.Material and methods. Hypoxic hypoxia was modeled on 87 outbred male rats using 200 liter chambers. The animals were under experimental conditions for four months. Rats were removed from the experiment after 30, 60, 90 and 120 days. After the animals were removed from the experiment, the lungs and the spleen were removed and fixed in 10% neutral buffer solution of Labiko formalin. Lung and spleen preparations were stained with hematoxylin and eosin and according to Van Gieson. For immunohistochemical studies, a panel of monoclonal antibodies was used: Anti-Mast Cell Tryptase antibody, Anti-Mast Cell Chymase antibody.Results. When modeling hypoxia in the structures of the lungs at the terms of 30 and 60 days, the content of predominantly tryptase-positive cells increased, and by the 90th and 120th days, the content of chymase-positive cells increased. By the end of the experimental exposure, the number of tryptase-positive cells increased by 3 times, and chymase-positive – by 7,7 times compared with the control. As the duration of the experiment increased, the presence of tryptase-positive cells in the spleen increased by 3,5 times, chymase-positive cells – by 7 times in the structures of the red and white pulp.Conclusion. During the formation of chronic hypoxic hypoxia in the body of laboratory animals, there is a redistribution of mast cells expressing tryptase and chymase. The most significant increase in the number of chymase-positive mast cells was noted both in the lungs and in the spleen.

O presente artigo é resultado da pesquisa de iniciação científica intitulada “Os conteúdos étnicoraciais nos livros didáticos de Manaus/Am: representações de mulheres negras e indígenas”, apoiada pela Universidade Federal do Amazonas - UFAM e financiada pela Fundação de Amparo a Pesquisa do Amazonas - FAPEAM. A pesquisa teve por objetivo discutir a Lei 11.645/2008 em vigência, analisando sua aplicação nos livros didáticos, e como as representações de gênero e raça se constroem nesse instrumento. O estudo constatou que muitas mudanças qualitativas ocorreram no que diz respeito à representação das populações negras e indígenas, mas que, ao buscarmos encontrar as mulheres pertencentes a esses grupos étnicos, ainda lidamos com um vazio, com uma invisibilidade e um silenciamento que lhes reduz quaisquer possibilidades de voz, nas Ciências, Artes, História, entre outras áreas.
A Igualdade de Gênero. Do Sonho Possível à Realidade Vivida: as contradições presentes na cooperativa das mulheres de Cametá/PA
Authors: Aquime Maria Salete Pantoja
Published: April 2023

O presente texto versa sobre a história de luta e resistência das mulheres do município Cametá, Estado do Pará, que criaram, no ano de 2004, uma Cooperativa formada só por mulheres produtoras, buscando caminhos de resistência contra o patriarcado e o machismo presentes nas organizações sociais. Trazem para um debate mais amplo a luta pela igualdade nas relações de gênero, dentro dos movimentos sociais, a fim de perceber que são, junto com os homens, peças fundamentais no processo de desenvolvimento social. O texto relata a história de luta dessas mulheres desde a década de 1980, onde buscam o empoderamento feminino, até os conflitos e contradições presentes atualmente na Cooperativa, como a presença masculina na organização, a venda dos produtos para os atravessadores e a dificuldade em ter a sua luta reconhecida, visível, sobretudo em espaços ligados às representações sociais, como os sindicatos e em outras cooperativas de produção.
Para além do Arco-íris: a relação dos homens gays com a cultura material na 18ª Parada do Orgulho LGBTI de Belém

Published: April 2023

Estudar os objetos que fazem parte das sociedades na contemporaneidade ajuda a compreender como a cultura material está inserida na vida das pessoas, fortalecem os seus processos de sociabilidades e contribuem com a ideia de pertencimento a um determinado coletivo social. Isso se torna mais complexo quando observamos essas materialidades em sua relação com as categorias de sexualidade entre homens gays belenenses. Essa pesquisa decorre de uma etnografia realizada durante a 18ª Parada do Orgulho LGBTI de Belém e teve como propósito analisar as vestimentas, calçados, marcas, cortes de cabelo e acessórios que foram utilizados por esses homens durante o evento, a partir do conceito do agenciamento dos objetos sobre as pessoas.
Cidadania Negada pela Torneira ou pelo Poço: mulheres marajoaras e suas dificuldades para acessar a água em Breves-PA
Authors: Santos Ana Maria Smith , Lima Elizandra Gomes de
Published: April 2023

Este artigo objetiva refletir sobre as dificuldades das mulheres marajoaras residentes no núcleo urbano de Breves-PA de acessar a água, compreendendo tal problema como uma negação de uma cidadania plena. É resultante do estudo de doutoramento em Antropologia Social de uma das autoras e do projeto de pesquisa PIBIC – Prodoutor. As metodologias aplicadas foram a Etnografia e a História Oral, respectivamente, realizadas junto às idosas participantes dos Centro de Referência de Assistência Social municipais nos anos de 2014 a 2018 e em 2019. O debate interpreta o acesso à água como um direito humano e que as mulheres de periferia são as mais atingidas com a água de péssima qualidade. Foi possível identificar as estratégias diárias para adquirir água e realizar suas tarefas, constituindo-se numa problemática constante em suas vidas.
O Perfil das Vítimas de Feminicídio na Região Metropolitana de Belém do Pará a partir das Reportagens do Caderno Policial do Jornal “Diário do Pará”, no Período de 2006 a 2015
Authors: Dias Ana Doroteia Santos
Published: April 2023

O artigo analisa o crime de Feminicídio a partir da análise do jornal Diário do Pará, entre os anos de 2006 a 2015. Os estudos sobre Feminicídio destacam que esse crime geralmente faz parte do estágio final do histórico de violência doméstica. Sendo assim, o objetivo é traçar o perfil das vítimas encontradas no caderno policial do jornal e relacioná-las às estatísticas computadas pelo Mapa da Violência, visando entender como as mulheres amazônidas são representadas nos discursos jornalísticos e até que ponto o jornal contribui para a perpetuação das estruturas de opressão feminina. O recorte temporal do estudo é demarcado a partir da implantação da Lei nº 11.340 “Lei Maria da Penha”, em vigor a partir do dia 22 de setembro de 2006, e a Lei n° 13.104 sancionada no dia 09 de março de 2015, que criminaliza o Feminicídio.
Uma Reflexão Sociológica do Desemprego entre as Mulheres no Brasil
Authors: Amaral Ivanete Modesto do
Published: April 2023

Este artigo procura refletir o desemprego definido inicialmente como uma categoria social objetiva – que se materializa em dados estatísticos institucionais/oficiais – e subjetiva – de percepção da realidade, onde esse fenômeno não afeta os indivíduos de maneira homogênea no espaço econômico da experiência de trabalho. É constituído pelas relações sociais, sobretudo pelas relações de gênero. Buscou-se estatísticas de órgãos oficiais como o IBGE e Ministério do Trabalho que, baseados na PNAD Contínua e Caged, mostram a vulnerabilidade das mulheres como as mais afetadas entre o contingente de desempregados no Brasil, nos anos 2017/2018. Os resultados apresentam o maior índice do desemprego recaindo sobre as mais jovens e com baixa escolaridade.

Published: April 2023

Este trabalho analisa a cartilha “O dia em que a Mata Sumiu”, do Programa de Apoio à Conservação Ambiental Bolsa Verde (PBV), com o objetivo de verificar a dimensão socioambiental da desigualdade e como esta se manifesta no discurso presente na cartilha e nas implicações direcionadas à população, sobretudo às mulheres, figuras centrais da política pública. Para isso, utilizamos a metodologia qualitativa baseada na leitura e observação crítica do seu discurso, articulada à literatura sobre desigualdade ambiental e estudos pós-coloniais, além de análises sobre o PBV e políticas afins. Argumentamos que os riscos ambientais afetam predominantemente grupos socialmente vulneráveis, configurando a distribuição desigual das consequências do desenvolvimento econômico. As dimensões da desigualdade de saber/poder identificadas são barreiras ao acesso dos direitos sociais, afetando a constituição da cidadania plena dessas populações, com importante reflexo sobre as mulheres

Published: April 2023

Este artigo objetivou conhecer o perfil das mulheres em situação de rua acolhidas no Abrigo João de Deus. Realizou-se análise documental em 08 prontuários referentes ao período de janeiro a agosto de 2019. O estudo teve abordagem quantitativa e qualitativa que permitiu caracterizar e analisar o perfil dessas mulheres. Os resultados apontaram que 63% das mulheres acolhidas são idosas, 62% não são alfabetizadas, 62% faziam uso de álcool e outras drogas, o conflito familiar com 50% dos motivos que levaram à situação de rua, 50% estão há mais de cinco anos institucionalizadas e 63% não possuem vínculo familiar. A análise dos dados evidenciou que essas mulheres passaram por um processo gradativo de perda de direitos e que a questão de gênero se constituiu em um agravante à situação de rua vivenciada por elas.

“Que Mulher Capoeira!”: trajetórias de resistência feminina na capoeira no Pará do século XXI
Authors: Camões Luciane De Sena
Published: April 2023

Este artigo intenciona discutir a trajetória de algumas capoeiristas no Pará, mulheres de diferentes lugares, espaços e estilos, interlocutoras de minha pesquisa de mestrado realizada entre os anos de 2017 e 2019. O título “Que mulher capoeira”, trata-se de um dos indícios históricos mais antigos de mulheres como capoeiras. Atualmente há um número significativo de capoeiristas ocupando esses espaços, entretanto a luta por visibilidade, protagonismo e lugar de fala continua constante. Neste trabalho, analiso as trajetórias de resistência de algumas capoeiristas atuantes no Pará e as relações de gênero evidenciadas. De modo específico, busco refletir sobre suas experiências na capoeira e as ações de fortalecimento. Com a pesquisa, nota-se avanços quanto ao reconhecimento e graduações, mas as mulheres continuam vivenciando situações de violência e reprodução do machismo e sexismo.

Published: April 2023

O serviço doméstico no Brasil é historicamente executado, em sua maioria, por mulheres negras, em muitos casos com idade elevada e com doenças crônicas, colocando este grupo, além de exposto ao novo coronavírus, em maior risco. Este artigo se propõe analisar impactos da pandemia da COVID-19 na categoria das trabalhadoras domésticas, apoiando-se em matérias jornalísticas nacionais e locais, e em entrevistas realizadas com uma doméstica residente na cidade de Belém/PA, com o intuito de apurar possíveis mudanças ocorridas na vida e no cotidiano de trabalhadoras durante esse período. Ao longo desta pesquisa, foi identificado elevada perda de postos de trabalho para a categoria; no caso da interlocutora, há o aumento da jornada de trabalho somada à constante preocupação de perder o emprego e a proteção de sua família.
