A REALIDADE AUMENTADA COMO OBJETO DE APRENDIZAGEM: AS NOVAS TECNOLOGIAS NA EAD

O presente estudo tem como objetivo verificar se a realidade aumentada (RA) pode favorecer, e de que forma, o desenvolvimento da autonomia e independência do aluno na educação a distância quando utilizada na criação de objetos de aprendizagem (OA). Para alcançar esse objetivo foi realizada uma pesquisa exploratória de caráter bibliográfico, a qual se baseou principalmente em artigos publicados em periódicos científicos e materiais disponibilizados na internet. Por meio dos exemplos apresentados observou-se que a realidade aumentada proporciona ao aluno maior interatividade com o conteúdo, como também, uma informação mais precisa e detalhada. Assim, pode-se concluir que a RA pode contribuir para o desenvolvimento da autonomia e independência do aluno na educação a distância. Contudo, para que se possa usufruir dos objetos de aprendizagem criados por meio da RA, é necessário suporte tecnológico específico, o que pode restringir o acesso a esse recurso inovador

Global conservation prioritization areas in three dimensions of crocodilian diversity

Lourenço-De-Moraes, R., Campos, F. S., Cabral, P., Silva-Soares, T., Nobrega, Y. C., Covre, A. C., & França, F. G. R. (2023). Global conservation prioritization areas in three dimensions of crocodilian diversity. Scientific Reports, 13(1), 1-13.

This study was financed in part by the 718 CAPES - Finance Code 001.Crocodilians are a taxonomic group of large predators with important ecological and evolutionary benefits for ecosystem functioning in the face of global change. Anthropogenic actions affect negatively crocodilians' survival and more than half of the species are threatened with extinction worldwide. Here, we map and explore three dimensions of crocodilian diversity on a global scale. To highlight the ecological importance of crocodilians, we correlate the spatial distribution of species with the ecosystem services of nutrient retention in the world. We calculate the effectiveness of global protected networks in safeguarding crocodilian species and provide three prioritization models for conservation planning. Our results show the main hotspots of ecological and evolutionary values are in southern North, Central and South America, west-central Africa, northeastern India, and southeastern Asia. African species have the highest correlation to nutrient retention patterns. Twenty-five percent of the world's crocodilian species are not significantly represented in the existing protected area networks. The most alarming cases are reported in northeastern India, eastern China, and west-central Africa which include endangered species with low or non-significant representation in the protected area networks. Our highest conservation prioritization model targets southern North America, east-central Central America, northern South America, west-central Africa, northeastern India, eastern China, southern Laos, Cambodia, and some points in southeastern Asia. Our research provides a global prioritization scheme to protect multiple dimensions of crocodilian diversity for achieving effective conservation outcomes.publishersversionpublishe

O princípio da autonomia como norteador das relações paciente-profissional em Odontologia: revisão da literatura

The understanding of bioethical principles is fundamental to guide clinical practice in the health area, and this includes dentistry. Autonomy, justice, beneficence, and non-maleficence determine the appropriate conduct, whether in the academic, research, or clinical care fields. Among them, autonomy is the most relevant principle in the context of oral health care, so that the disrespect to this guideline may cause serious consequences for the patient who may feel coerced to do something that is not in his interest, and for the professional who may incur in ethical infraction, or even suffer a civil or even criminal lawsuit. The aim of this study was to describe how the bioethical principle of autonomy can be applied in patient-professional relationships in dentistry. Autonomy is applied at all moments of the very personal relationship between patient and professional, from the reception of the patient to the determination of the treatment plan and the execution of the procedures. The informed consent seems to be the fundamental document to ensure that the patient can safely make his choice about the treatment plan. Social status and financial factors can have a direct impact on the selection of the procedure, which can compromise the patient's autonomy. Thus, this study described the ways in which the bioethical principle of autonomy is applied in patient-professional relationships in dentistry, and further studies in this field are suggested, to keep professionals updated in the field of bioethics.O entendimento dos princípios bioéticos é fundamental para nortear a prática clínica na área da saúde, e isso inclui a Odontologia. A autonomia, a justiça, a beneficência e a não-maleficência determinam as condutas adequadas seja em âmbito acadêmico, de pesquisa ou do atendimento clínico. Dentre eles, a autonomia é o princípio mais relevante no contexto da atenção em saúde bucal, de forma que o desrespeito a esta diretriz, pode ocasionar graves consequências para o paciente que pode se sentir coagido a fazer algo que não seja de seu interesse, e para o profissional que pode incorrer em infração ética, ou mesmo sofrer um processo na esfera cível ou até criminal. O objetivo deste trabalho foi descrever as formas de aplicação do princípio bioético da autonomia nas relações paciente-profissional em Odontologia, para tanto foi realizada uma revisão da literatura acerca da temática. A autonomia se aplica em todos os momentos da relação personalíssima entre paciente e profissional, desde a recepção do paciente, até a determinação do plano de tratamento e da execução dos procedimentos. O termo de consentimento livre e esclarecido parece ser o documento fundamental para garantir que o paciente possa fazer sua escolha acerca do plano de tratamento de forma segura. A condição social e fatores financeiros podem impactar diretamente na seleção do procedimento, podendo então comprometer o uso da autonomia por parte do paciente. Sendo assim, foi possível a partir deste estudo descrever as formas de aplicação do princípio bioético da autonomia nas relações paciente-profissional em Odontologia, e ainda se sugere que mais estudos neste campo sejam feitos, de forma a manter profissionais atualizados no âmbito da bioética

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
