Educational software and improvement of first grade school students’ knowledge about prevention of overweight and obesity
To evaluate the effects of educational softwareto improve first grade school students’ knowledge aboutprevention of overweight and obesity. Methods. Thisnon-controlled trial with a before-and-after evaluationwas carried out in an school located in the municipalityof Divinópolis (Brazil) among 71 students aged 6 to10 years. The educational software about preventionof overweight and obesity was designed and thenvalidated. The educational intervention comprised theuse of the software. Before and after of the interventionwe applied a questionnaire based on the Ten Steps toHealthy Eating for Children, proposed by the BrazilianMinistry of Health. Results. Comparing the times beforeand after application of the educational software,we observed statistically significant differences inproportion of questions answered correctly by firstgrade school students, mainly concerning daily eatingof healthy and unhealthy food, adequate preparationof food and importance of exercise. Conclusion. Thisstudy highlights the importance of educational actionsusing software to build knowledge of first grade schoolstudents about prevention of overweight and obesity.Objetivo.

Ensaio não controlado com avaliação antes e depois,
realizada em uma escola municipal de Divinópolis
(Brasil). Participaram 71 escolares com idade entre
6 e 10 anos. O software educativo sobre prevenção
de sobrepeso e obesidade foi construído e validado. A
intervenção educativa foi constituída pela utilização deste
software. Antes e depois da intervenção foi aplicado um
questionário baseado nos Dez Passos da Alimentação
Saudável da Criança, proposta pelo Ministério da Saúde.
Resultados. Comparando os momentos antes e depois
da utilização do software educativo se observaram
diferenças estatisticamente significativas na proporção
de perguntas respondidas corretamente pelos escolares,
especialmente no que se refere à ingesta diária de
alimentos saudáveis e não saudáveis, preparação
adequada de alimentos e importância da atividade física.
Conclusão. O presente estudo ressalta a importância das
ações educativas por meio de um software na construção

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network
International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
