The reasons are varied and consequential. Even if the settings of the courses of technical education institutions may suffer considerable changes, especially in provision of Law No. 11. 741 (2008). In this meaning, there is the importance of knowing the possible barriers traveled by students invested in this course and its dropouts them. Enabling new endowments in avoiding these outputs in order to search the interaction school community and technical student, stating that each member in their functions, have their responsibilities with this student body, their job prospects and even the contribution of the environment of pedagogical actions in Resolution of the problem avoidance. Postulating on the objectification of check truancy as a major challenge put to Codai in terms of access and permanence in Agricultural Technician course students, so that, to achieve this objectification leaned in targeted theoretical knowledge the topic and arranged in books, scientific articles, and electronic search, above all, support in the annotated in laws, decrees and resolutions that address the permeate of Brazilian education. Theoretical support that was the basis for general observations from the perspective of a documentary research on dropout cases occurring between 2010 and 2014, the technical agronomy course offered by the Agricultural College Dom Augustine Ikas - Codai / UFRPE. Located in the municipality of S?o Louren?o da Mata - PE. In addition to field research involving managers, teachers and alumni (escaped) this educational institution. So that the results may contribute to the existing research on the subject involved, but also be supportive knowledge of school life and the barriers faced as the causes of evasion, to take certifications as the school context and the challenges of young people are confronted in their professional preparation and factors such as economic issue; work and help the family; lack of motivation; the unsuitability for the course; lack of reconciliation between work and progress; Course expectations do not reach the expected, among others. Above all, the recognition that evasion back losses to the students, society and the public coffers / A evas?o como problem?tica do ensino brasileiro, vem se estendendo em todos os n?veis educacionais, inclusive em cursos t?cnicos em Agropecu?ria. Os motivos s?o variados e consequentes. Mesmo que as configura??es dos cursos das institui??es de Ensino T?cnico venham sofrer transforma??es consider?veis, em disposi??o principalmente da lei n? 11. 741 (2008). Nessa significa??o, verifica-se a import?ncia de se conhecer as poss?veis barreiras percorridas pelos alunos investidos nesse curso e suas desist?ncias dos mesmos. Possibilitando novas investiduras no evitar dessas sa?das com vista ? busca ? intera??o comunidade escolar e o estudante t?cnico, afirmando que cada membro, em suas fun??es, possui suas responsabilidades com esse alunado, suas perspectivas profissionais e at? mesmo a contribui??o da conjuntura de a??es pedag?gicas na resolu??o do problema evas?o. Postulando-se na objetiva??o de verificar a evas?o escolar como um dos grandes desafios posto ao Codai, em respeito ao acesso e perman?ncia de alunos do curso de T?cnico em Agropecu?ria, de forma que, para o alcance dessa objetiva??o debru?ou-se em conhecimentos te?ricos direcionados ao tema e dispostos em livros, artigos cient?ficos, e pesquisa eletr?nica, sobretudo, com apoio nos averbados em leis, decretos e resolu??es que contemplam o perpassar da educa??o brasileira. Suporte te?rico que foi a base para considera??es gerais sob a ?tica de uma pesquisa documental sobre casos de evas?o ocorridos entre os 2010 e 2014, no curso t?cnico de agropecu?ria oferecido pelo Col?gio Agr?cola Dom Agostinho Ikas ? Codai/ UFRPE. Situado no Munic?pio de s?o Louren?o da Mata ? PE. Somado-se a uma pesquisa de campo envolvendo gestor, professores e ex-alunos (evadidos) dessa institui??o de ensino. De forma que, os resultados obtidos venham contribuir com as pesquisas j? existentes quanto ? tem?tica envolvida, mas tamb?m ser suporte de conhecimentos da viv?ncia escolar e as barreiras enfrentadas como as causas da evas?o, no sentido de levar certifica??es quanto o contexto escolar e os desafios de jovens em defrontarem-se em sua prepara??o profissional e fatores como: quest?o econ?mica; trabalhar e ajudar a fam?lia; falta de motiva??o; a n?o adequa??o ao curso; falta de concilia??o entre trabalho e curso; expectativas do curso n?o alcan?am o esperado, entre outros. Sobretudo, o reconhecimento de que a evas?o tr?s preju?zos aos pr?prios alunos, a sociedade e aos cofres p?blicos

Altera??es do ciclo sono-vig?lia moduladas por Dopamina e suas consequ?ncias Mnem?nicas

No. of bitstreams: 1 ArthurSCF_DISSERT.pdf: 1292069 bytes, checksum: 075e39981847ff7574f2e91e90afcba3 (MD5) Previous issue date: 2012-04-09 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Neuroscience is on a rise of discoveries. Its wide interdisciplinary approach facilitates a more complex understanding of the brain, covering various areas in depth. However, many phenomena that fascinate human kind are far from being fully elucidated, such as the formation of memories and sleep. In this study we investigated the role of the dopaminergic system in the process of memory consolidation and modulation of the phases of sleep-wake cycle. We used two groups of animals: wildtype mice and hiperdopaminergic mice, heterozygous for the gene encoding the dopamine transporter protein. We observed in wild-type mice that the partial blockade of the D2 dopamine receptor by the drug haloperidol caused deficits in memory consolidation for object recognition, as well as a significant reduction in the duration of rapid eye movement sleep (REM). We also found a mnemonic deficit without pharmacological intervention in hiperdopaminergic animals; this deficit was reversed with haloperidol. The results suggest that dopamine plays a key role in memory consolidation for object recognition. The data also support a functional relationship between the dopaminergic system and the modulation of REM sleep / As descobertas da neuroci?ncia est?o em franca ascens?o. A sua grande interdisciplinaridade facilita uma abordagem mais complexa do c?rebro, abrangendo com profundidade diversas ?reas. No entanto, muitos fen?menos que fascinam a humanidade est?o longe de ser completamente elucidados; nesse contexto se encontra a rela??o entre a consolida??o das mem?rias e o sono. Nesse trabalho investigamos o papel de parte do sistema dopamin?rgico no processo de consolida??o de mem?rias e na modula??o das fases do ciclo sono-vig?lia. Utilizamos dois grupos de animais: camundongos selvagens e camundongos hiperdopamin?rgicos, heterozigotos para o gene que codifica a prote?na transportadora de dopamina. Observamos em camundongos selvagens que o bloqueio parcial dos receptores dopamin?rgicos da fam?lia D2 pela droga haloperidol provocou d?ficits na consolida??o da mem?ria de reconhecimento de objetos, bem como uma redu??o significativa do tempo de dura??o do sono de movimento r?pido dos olhos (MRO). Observamos tamb?m um d?ficit, sem interven??o farmacol?gica, em animais hiperdopamin?rgicos; tal d?ficit foi revertido com a droga haloperidol. Os resultados indicam que a dopamina desempenha um papel importante no processo de consolida??o de mem?rias de reconhecimento de objetos. Os dados tamb?m corroboram uma rela??o funcional entre o sistema dopamin?rgico e a modula??o da fase do sono MRO
