GERAÇÃO “Z” E AMIZADE VIRTUAL

Introdução: Às relações sociais são próprias da vida do ser humano, quer elas aconteçam de maneira presencial, com pessoas que conhecem por toda uma vida ou de forma virtual com desconhecidos e referidos por apelidos, os quais são seus nomes na Internet e podem, ou não, os ser na realidade. Mas afinal, será mesmo que o mundo virtual não é também a realidade e não tem, possivelmente, impacto na formação subjetiva do ser, sua socialização e relações de amizade? Em específico dos chamados nativos digitais da Geração Z. Objetivo Geral: Entender como a Geração “Z” tem a sua formação subjetiva através das relações de amizade virtual. Objetivos Específicos: Conhecer os hábitos da Geração “Z” no que diz respeito a redes sociais; verificar qual o papel a proximidade física tem aos olhos dessa geração quanto à amizade; definir como ocorre a relação entre Gen Z e tecnologia em seus relacionamentos e estabelecer como os tratos de amizade virtuais impactam na formação do indivíduo. Metodologia: Foi realizada uma pesquisa bibliográfica descritiva, por meio de abordagem qualitativa, utilizando de fontes secundárias, através do método indutivo, efetuando coleta bibliográfica, nas plataformas: Google Acadêmico e Scielo. Foram utilizados artigos do ano de 2017 a 2021, através das palavras chaves: “amizade”, “geração Z”, “mídias” e  “sociais”. Foram encontrados 15 (quinze) artigos, os quais serão a base do estudo desta revisão literária. Considerações Parciais: A presente pesquisa encontra-se em andamento com os seguintes resultados parciais: as mídias sociais converteram a humanidade em seres altamente conectados, com algumas pessoas se viciando em seu uso, enquanto coincidiu com o declínio aparente da saúde mental humana. Esse tipo de socialização não parece ser o suficiente para saldar a necessidade de contato frente a frente com outro humano, observa-se que os adolescentes podem ser mais suscetíveis a esse vício e que a forma de contato majoritariamente online pode estar diminuindo a habilidade humana de comunicação presencialmente e essa falta de contato humano real pode levar ao adoecimento físico e psicológico

Effect of a gel containing pilocarpine on vaginal atrophy in castrated rats

OBJECTIVES: To evaluate the effect of Carbopol gel formulations containing pilocarpine on the morphology and morphometry of the vaginal epithelium of castrated rats. METHODS: Thirty-one female Wistar-Hannover rats were randomly divided into four groups: the control Groups I (n=7, rats in persistent estrus; positive controls) and II (n=7, castrated rats, negative controls) and the experimental Groups, III (n=8) and IV (n=9). Persistent estrus (Group I) was achieved with a subcutaneous injection of testosterone propionate on the second postnatal day. At 90 days postnatal, rats in Groups II, III and IV were castrated and treated vaginally for 14 days with Carbopol gel (vehicle alone) or Carbopol gel containing 5% and 15% pilocarpine, respectively. Next, all of the animals were euthanized and their vaginas were removed for histological evaluation. A non-parametric test with a weighted linear regression model was used for data analysis (

A social and ecological assessment of tropical land uses at multiple scales: the Sustainable Amazon Network

Science has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazonia Sustentavel, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers three advantages for addressing land-use sustainability problems: (i) the collection of synchronized and co-located ecological and socioeconomic data across broad gradients of past and present human use; (ii) a nested sampling design to aid comparison of ecological and socioeconomic conditions associated with different land uses across local, landscape and regional scales; and (iii) a strong engagement with a wide variety of actors and non-research institutions. Here, we elaborate on these key features, and identify the ways in which RAS can help in highlighting those problems in most urgent need of attention, and in guiding improvements in land-use sustainability in Amazonia and elsewhere in the tropics. We also discuss some of the practical lessons, limitations and realities faced during the development of the RAS initiative so far.Keywords: Social–ecological systems, Tropical forests, Land use, Interdisciplinary research, Sustainability, Trade-off

The use of Facebook in health education: perceptions of adolescent students

ABSTRACT Objective: understand the perceptions of adolescent students regarding the use of Facebook social media in sexual and reproductive health learning in the Family Health Strategy. Method: a qualitative, descriptive study developed with 96 adolescents from a public school and a private school in Fortaleza-CE who concluded an educational intervention using Facebook. The information was collected in the online environment itself, as well as in a questionnaire applied in person. For the collection and analysis of this information, netnography was used. Results: Facebook contributed to the sexual and reproductive health education in an interactive, playful and practical way, reducing the embarrassment of some adolescents to converse on the subject, and brought adolescents closer to the health service, by strengthening their bond with Health professionals. Final considerations: health professionals should recognize that such virtual spaces on the Internet offer potential for the production of health care, especially among adolescents

Persistent estrus (Group I) was achieved with a subcutaneous injection of testosterone propionate on the second postnatal day. At 90 days postnatal, rats in Groups II, III and IV were castrated and treated vaginally for 14 days with Carbopol gel (vehicle alone) or Carbopol gel containing 5% and 15% pilocarpine, respectively. Next, all of the animals were euthanized and their vaginas were removed for histological evaluation. A non-parametric test with a weighted linear regression model was used for data analysis (p<0.05). RESULTS: The morphological evaluation showed maturation of the vaginal epithelium with keratinization in Group I, whereas signs of vaginal atrophy were present in the rats of the other groups. Morphometric examinations showed mean thickness values of the vaginal epithelium of 195.10±12.23 μm, 30.90±1.14 μm, 28.16±2.98 μm and 29.84±2.30 μm in Groups I, II, III and IV, respectively, with statistically significant differences between Group I and the other three groups (p<0.0001) and no differences between Groups II, III and IV (p=0.0809). CONCLUSION: Topical gel formulations containing pilocarpine had no effect on atrophy of the vaginal epithelium in the castrated female rats
