Este artigo tem por objetivo analisar e discutir as questões tratadas no Espaço de diálogo e prática (EDP) “Gênero, sexualidade e diversidade na escola”, dentro do X Encontro Nacional de Ensino de Geografia - Fala Professor(a), que ocorreu em Fortaleza-CE, em julho de 2023, na Universidade Estadual do Ceará - Campus Itaperi. Foram apresentados nove trabalhos e as doze pessoas participantes do EDP trocaram impressões de que é preciso fortalecer nacionalmente os espaços de troca e ações coletivas acerca das questões de gênero e sexualidade, sobretudo no âmbito escolar. Esta discussão aqui não apenas destaca a necessidade, mas também demonstra a viabilidade de incorporar essas questões no currículo escolar. As experiências apresentadas no EDP reforçam a ideia de que esses assuntos são relevantes para a vida cotidiana e, portanto, devem ser abordados nas escolas como uma medida para combater a violência e as desigualdades. A promoção de uma educação não sexista representa um compromisso com a mudança e é ferramenta essencial com relevância social e política.

Published: March 2024

Objective: The objective is to utilize open-source artificial intelligence tool Teachable Machine to detect dental caries.
Subjects and Research Methods: cross-sectional description. The research involved analyzing a total of 2,063 digital images, comprising 1,563 images showing dental caries and 500 images depicting teeth without any signs of dental caries.
Results: Among the 1,563 images featuring dental caries, the recognition tool accurately identified 1,512 images (96%), while 51 images remained undetected, representing 4% of the total. Among the entire set of 2,063 images, encompassing both those with and without dental caries, 1,512 images were accurately identified (73.3%), while 551 images (26.7%) were not detected to have dental caries.
Conclusion: The study on 1,563 images with dental caries using the Teachable Machine learning tool yielded promising results, achieving a high accuracy rate of 96%. However, when applied to the mixed dataset of 2,063 images, the accuracy rate for identifying images with dental caries dropped to only 73.3. The variance is ascribed to the initial stages of dental caries, which closely resemble the color of healthy tooth enamel. Therefore, the research team proposes the necessity for additional data on this form of decay to enhance classification and identification accuracy.

Aims: The aim of this study is to assess people's perceptions of bamboo's potential to replace wood.
Study Design: Introduction, methodology, results, and conclusion.
Place and Duration of Study: This study was carried out between April and July 2022 in an agro ecological rainforest zone in Cameroon, more specifically in the Ebolowa 2 Council, where there are significant bamboo resources.
Methodology: 5 villages were chosen for the study, due to their accessibility and proximity to the urban centre. A purposive sampling based on proximity to bamboo stands was applied and 75 households were surveyed using a semi-structured questionnaire, with 30% of respondents being women. In addition, observations were made directly on the field to identify the uses made of bamboo by peasants in the various villages.
Results: The results show that the collection of firewood is the second greatest anthropogenic threat to the forest after agriculture. An analysis of wood energy requirements shows that they increase with household size. 51.8% of the households sampled consume an average of 2 to 5 50-cm steres, i.e. around 1.6 to 4 m³ of firewood/week. The landscape of the study area is marked by a strong presence of tree nurseries built using bamboo as a substitute for wood. Bamboo is used by 70.3% of the population sampled in the study area. However, the value of bamboo is still very low, given the 5 areas of use identified. Nonetheless, it is seen as a good alternative to wood by 75% of these households.
Conclusion: The results of this study provide a database that can be used to help promote and develop the bamboo sector in rural forest areas of Cameroon.

Integrating professionalism in early medical education: The theory and application of reflective practice in the anatomy curriculum
Authors: Lachman Nirusha , Pawlina Wojciech 
Published: May 2006

AbstractRenewed emphases on teaching professionalism require physicians to develop the ability to critically reflect upon their own decisions. Innovative programs that address teaching professionalism within medical curricula have been implemented in almost all medical schools. The foundation for many of these programs is “reflection,” which is regarded as a core skill in professional competence. In order to achieve the desired outcomes and meet the demands of a required curriculum, an understanding of educational concepts in the designing of medical curricula is essential. Educators recognize that, for most medical students, professional growth is initiated during the first year of the medical curriculum and, therefore, traditionally pure content delivery courses such as first year anatomy course are being utilized now in order to explore issues related to critical thinking and professionalism. As a result, learning strategies such as “reflective practice” are beginning to play an important role in curriculum design. This article provides an overview of the theory of reflective practice, and demonstrates how reflective practice may be integrated into the anatomy curriculum. In order to incorporate reflective exercises into a curriculum, the basic elements of a reflective process are defined, strategies to implement reflective exercises within the course are described, and the benefits of reflective practice are highlighted. Therefore, in creating an environment that fosters reflective learning, the gap between theory and practice may be consolidated, which in the context of anatomy promotes the issue of teaching for relevance and clinical application.

Mild Copper‐Catalyzed Vinylation Reactions of Azoles and Phenols with Vinyl Bromides
Authors: Taillefer Marc , Ouali Armelle , Renard Brice , Spindler Jean‐Francis 
Published: May 2006

AbstractAn efficient and straightforward copper‐catalyzed method allowing vinylation of N‐ or O‐nucleophiles with di‐ or trisubstituted vinyl bromides is reported. The procedure is applicable to a broad range of substrates since N‐vinylation of mono‐, di‐, and triazoles as well as O‐vinylation of phenol derivatives can be performed with catalytic amounts of copper iodide and inexpensive nitrogen ligands 3 or 8. In the case of more hindered vinyl bromides, the use of the original bidentate chelator 8 was shown to be more efficient to promote the coupling reactions than our key tetradentate ligand 3. The corresponding N‐(1‐alkenyl)azoles and alkenyl aryl ethers are obtained in high yields and selectivities under very mild temperature conditions (35–110 °C for N‐vinylation reactions and 50–80 °C for O‐vinylation reactions). Moreover, to our knowledge, this method is the first example of a copper‐catalyzed vinylation of various azoles. Finally, this protocol, practical on a laboratory scale and easily adaptable to an industrial scale, is very competitive compared to the existing methods that allow the synthesis of such compounds.

Published: May 2006

AbstractBACKGROUNDConcerns exist regarding the ability to select patients with lobular carcinoma for breast‐conserving therapy (BCT) using mammography. The purpose of this study was to compare the conversion rate from BCT to mastectomy among patients with lobular (ILC) and ductal carcinoma (IDC), and to compare the number of resections needed to obtain negative margins.METHODSIn all, 349 patients with pure or mixed ILC were identified from a database and 318 were successfully matched to 2 controls with IDC on the basis of year of diagnosis, menopausal status, and stage of disease. Conditional logistic regression was used to control for matching.RESULTSPatients with ILC were older, had larger tumors (2.6 vs. 2.1 cm; P<.001), and were more likely to have contraindications to BCT (25% vs. 20%). In patients thought to be candidates for BCT, no difference in success rate was noted on the basis of histologic type after controlling for age and stage. In those undergoing BCT, no difference in the number of procedures was seen on the bases of histology after adjustment for age and stage.CONCLUSIONSPatients with ILC are not more likely to fail BCT than those with IDC, nor do they require more operations to obtain negative margins. These results do not support the use of more extensive preoperative evaluation such as magnetic resonance imaging in patients with ILC. Cancer 2006. © 2006 American Cancer Society.
Vector valued Fourier analysis on unimodular groups
Authors: Lee Hun Hee 
Published: May 2006

AbstractThe notion of Fourier type and cotype of linear maps between operator spaces with respect to certain unimodular (possibly nonabelian and noncompact) group is defined here. We develop analogous theory compared to Fourier types with respect to locally compact abelian groups of operators between Banach spaces. We consider the Heisenberg group as an example of nonabelian and noncompact groups and prove that Fourier type and cotype with respect to the Heisenberg group implies Fourier type with respect to classical abelian groups.

Protein kinase Cε and development of squamous cell carcinoma, the nonmelanoma human skin cancer
Authors: Verma Ajit K. , Wheeler Deric L. , Aziz Moammir H. , Manoharan Herbert 
Published: May 2006

AbstractProtein kinase C (PKC) represents a large family of phosphatidylserine (PS)‐dependent serine/threonine protein kinases. At least five PKC isoforms (α, δ, ε, η, and ζ) are expressed in epidermal keratinocytes. PKC isoforms are differentially expressed in proliferative (basal layer) and nonproliferative compartments (spinous, granular, cornified layers), which exhibit divergence in their roles in the regulation of epidermal cell proliferation, differentiation, and apoptosis. Immunocytochemical localization of PKC isoforms indicate that PKCα is found in the membranes of suprabasal cells in the spinous and granular layers. PKCε is mostly localized in the proliferative basal layers. PKCη is localized exclusively in the granular layer. PKCδ is detected throughout the epidermis. PKC isozymes exhibit specificities in their signals to the development of skin cancer. PKCε, a calcium‐insensitive PKC isoform mediates the induction of squamous cell carcinoma (SCC) elicited either by the DMBA‐TPA protocol or by repeated exposures to ultraviolet radiation (UVR). PKCε overexpression, which sensitizes skin to UVR‐induced carcinogenesis, suppresses UVR‐induced sunburn (apoptotic) cell formation, and enhances both UVR‐induced levels of TNFα and hyperplasia. UVR‐induced sunburn cell formation is mediated by Fas/Fas‐L and TNFα NFR1 extrinsic apoptotic pathways. The death adaptor protein termed Fas‐associated death domain (FADD) is a common adaptor protein for both of these apoptotic pathways. PKCε inhibits UVR‐induced expression of FADD leading to the inhibition of both apoptotic pathways. It appears that PKCε sensitizes skin to the development of SCC by UVR by transducting signals, which inhibit apoptosis on one hand, and enhances proliferation of preneoplastic cells on the other hand. © 2006 Wiley‐Liss, Inc.
DSC perfusion MRI—Quantification and reduction of systematic errors arising in areas of reduced cerebral blood flow
Authors: Carpenter Trevor K. , Armitage Paul A. , Bastin Mark E. , Wardlaw Joanna M. 
Published: May 2006

AbstractDynamic susceptibility contrast (DSC)‐MRI is commonly used to measure cerebral perfusion in acute ischemic stroke. Quantification of perfusion parameters involves deconvolution of the tissue concentration‐time curves with an arterial input function (AIF), typically with the use of singular value decomposition (SVD). To mitigate the effects of noise on the estimated cerebral blood flow (CBF), a regularization parameter or threshold is used. Often a single global threshold is applied to every voxel, and its value has a dramatic effect on the CBF values obtained. When a single global threshold was applied to simulated concentration‐time curves produced using exponential, triangular, and boxcar residue functions, significant systematic errors were found in the measured perfusion parameters. We estimate the errors obtained for different sampling intervals and signal‐to‐noise ratios (SNRs), and discuss the source of the systematic error. We present a method that partially corrects for the systematic error in the presence of an exponential residue function by applying a linear fit, which removes underestimates of long mean transit time (MTT) and overestimates of short MTT. For example, the correction reduced the error at a temporal resolution of 2.5 s and an SNR of 30 from 29.1% to 11.7%. However, the error is largest in the presence of noise and at MTTs that are likely to be encountered in areas of hypoperfusion; furthermore, even though it is reduced, it cannot be corrected for exactly.
