Reflexões sobre as interfaces entre ações formativas EDUSEX e as tecnologias digitais: um estudo de caso interpretativo-dialético

These are the first reflections of a case study on the formative actions experienced and carried out by the Educators Training and Sexual Education EDUSEX Research Group CNPq/UDESC - Brazil and in its current interfaces with digital technologies, as well as the progressive transit of training models and expository teaching and learning practices, towards more interactive possibilities, supported by new technologies, from a perspective of learning by doing. These are the guiding questions of this investigation: (a) What formative actions were developed by the Edusex Group, specifically those related to digital technology? (b) What are the characteristics of these formative actions and their interfaces with digital technologies? In this section, we seek to reflect on the actions taken and, with that in mind, we have recurred to some contemporary theorists who study the subject of sexual education. The study is qualitative and follows the socio-critical paradigm assuming a global and dialectical view of reality. In the case study we used the technique of dialectical hermeneutic analysis in the data analysis. The findings pointed out that the formative actions seek: (1) to publicize and facilitate access to research and knowledge of the theme of sexuality in a perspective; (2) to assist in the reflection of current approaches on the theme; (3) to equip undergraduate, masters and doctorate students to make didactic-pedagogical use of digital technologies and other formats; (4) to carry out the didactic transposition of the contents learned, transforming it into a formative tool, later used in the training of teachers and students of elementary schools.Se trata de las primeras reflexiones de un estudio de caso sobre las acciones formativas experimentadas y realizadas por el Grupo de Pesquisa EDUSEX Formación de Educadores y Educación Sexual CNPq/UDESC - Brasil y en sus interfaces hoy con las tecnologías digitales, así como, el tránsito progresivo de modelos de formación y prácticas de enseñanza y aprendizaje expositivas, para posibilidades más interactivas, apoyadas en las nuevas tecnologías, en una perspectiva de aprender haciendo. Son interrogantes orientadores de esta investigación: (a) ¿Cuáles son las acciones formativas elaboradas por el Grupo Edusex, más específicamente las relacionadas con la tecnología digital? (b) ¿Cuáles son las características de estas acciones formativas y sus interfaces con las tecnologías digitales? En este recorte, buscamos reflexionar sobre las acciones realizadas y para ello, recurrimos a algunos teóricos contemporáneos que estudian la temática de la educación sexual. El estudio es de cuño cualitativo y sigue pautado en el paradigma socio-crítico asumiendo una visión global y dialéctica de la realidad. En el estudio de caso utilizamos en el análisis de los datos la técnica de análisis hermenéutica dialéctica. Los hallazgos apuntaron que las acciones formativas buscan: (1) dar a conocer y facilitar el acceso a la investigación y a los conocimientos de la temática de la sexualidad em una perspectiva; (2) auxiliar en la reflexión de enfoques actuales sobre la temática; (3) instrumentalizar a los alumnos y alumnas, graduandos/as, maestrandos/as y doctorandos/as, a hacer el uso didáctico-pedagógico de las tecnologías digitales y de otros formatos; (4) realizar la transposición didáctica de los contenidos aprendidos, transformándola en una herramienta formativa, utilizada posteriormente para la formación de profesores y estudiantes de las escuelas de enseñanza básica.Trata-se das primeiras reflexões de um estudo de caso sobre as ações formativas experienciadas e realizadas pelo Grupo de Pesquisa EDUSEX, Formação de Educadores e Educação Sexual CNPq/UDESC – Brasil, em suas interfaces hoje com as tecnologias digitais, bem como o trânsito progressivo de modelos de formação e práticas de ensino e aprendizagem expositivas, para possibilidades mais interativas, apoiadas nas novas tecnologias, numa perspectiva de aprender fazendo.

Algumas reflexões necessárias sobre o fenômeno Sexting na busca de prevenção de riscos para adolescentes em suas relações com as mídias

Este artigo pretende levar o leitor a refletir sobre uma prática cada vez mais comum entre crianças, adolescentes e adultos, denominada Sexting e será dividido em três momentos. No primeiro, é realizada uma breve descrição do que representou a Modernidade em termos de transformações na humanidade e o momento atual, além de uma reflexão sobre a questão da individualidade. No segundo, são feitos alguns apontamentos sobre quem é o adolescente de hoje. No outro momento, é apresentada uma contextualização do fenômeno Sexting, por meio de uma breve revisão conceitual sobre ele apontando, inclusive, para a situação de riscos a que podem se expor os adolescentes ao praticá-lo. Para concluir, aponta-se um caminho a ser trilhado para um necessário estudo da compreensão de adolescentes sobre o Sexting.Palavras-chave: Sexting; Educação sexual; Adolescentes

Recogida y análisis de datos desde una perspectiva fenomenológica: registros de las redes sociales como corpus documental en una investigación en educación

A pesquisa fenomenológica numa investigação qualitativa é peculiar por trazer ao campo epistemológico a lógica da compreensão do fenômeno em si por meio de num exercício exaustivo de redução, na busca da essência do fenômeno no momento em que ele acontece. O desafio neste estudo ainda vai mais além: realizar as reduções por meio das primeiras recolhas e análises de dados de postagens realizadas em dois grupos criados no Facebook, de duas Turmas de escolares participantes de um Projeto Educativo intitulado Projeto Aprender a Conhecer: Pesquisar de Corpo Inteiro (PAC), que ocorre numa Escola Pública Brasileira, objeto desta investigação. Diante disso, este artigo apresenta um pequeno extrato de um doutoramento em curso. Os resultados apontaram que uma análise fenomenológica de documentos virtuais requer um olhar bastante criterioso, bem como a necessidade da utilização de um enxerto-hermenêutico, que no nosso ponto de vista, permitiu emergir as primeiras tendências da análise. Enfim, as asserções desvelaram a categoria participação como um dos elementos que poderá levar todos os envolvidos no projeto a aprender juntos, mas também, as contradições em relação ao entendimento e compreensão do tipo de participação dos estudantes no projeto, que ora parece tutelada/ restrita, ora parece plena/ativa. Tal tendência parece-nos essencial para a compreensão do PAC e sua influência na construção de num novo espaço/tempo de fazer escola.A Phenomenological research in a qualitative investigation is peculiar to bring to the epistemological field the logic of the understanding of the phenomenon in itself through an exhaustive exercise of reduction, in search of the essence of the phenomenon at the moment in which it happens. The challenge in this study goes even further: to carry out the reductions through the first collection and analysis of data from postings made in two groups created on Facebook, from two classes of schoolchildren participating in the Educational Project “Learning to Know: research with Whole Body”, which occurs in a Brazilian Public School, object of this study. Therefore, this article presents a small extract of an ongoing PhD. The results point out that a phenomenological analysis of virtual documents requires a very critical observation as well as the need to use a hermeneutic-graft, which in our view allowed us to emerge the first trends of analysis. Finally, the assertions revealed the participation category as one of the elements that could lead all involved in the project to learn together, but also, the contradictions regarding the understanding and comprehension of the type of students' participation in the project, which sometimes seems to be supervised / restricted , sometimes seems full / active. Such a trend seems to us essential for the understanding of the PAC and its influence on the construction of a new space / time to do school.La investigación fenomenológica en una investigación cualitativa es peculiar por traer al campo epistemológico la lógica de la comprensión del fenómeno en sí, por medio de un ejercicio exhaustivo de reducción, en la búsqueda de la esencia del fenómeno en el momento en que sucede. El desafío en este estudio va aún más allá: realizar las reducciones por medio de las primeras recogidas y análisis de datos de publicaciones realizadas en dos grupos creados en Facebook, de dos clases de escolares participantes en un proyecto educativo titulado: “Proyecto Aprender a Conocer: Investigar de Cuerpo Entero (PAC)”, que se desarrolla en una Escuela Pública Brasileña, objeto de esta investigación. Por lo que este artículo presenta un pequeño extracto de un doctorado en curso. Los resultados apuntan a que un análisis fenomenológico de documentos virtuales requiere una mirada bastante cuidadosa, así como, se refiere la necesidad de la utilización de un injerto-hermenéutico, que desde nuestro punto de vista, permitió emerger las primeras tendencias del análisis. Finalmente, los hallazgos revelaron la categoría participación como uno de los elementos que podría llevar a todos los involucrados en el proyecto, a aprender juntos, pero también, se desvelaron las contradicciones en relación al entendimiento y a la comprensión del tipo de participación de los estudiantes en el proyecto, que ahora parece estar supervisada / restringida, y completa / activa. Dicha tendencia nos parece esencial para la comprensión del PAC y su influencia en la construcción de un nuevo espacio / tiempo para hacer escuela.publishe

Preservation of bovine preantral follicle viability and ultra-structure after cooling and freezing of ovarian tissue

Bovine preantral follicles within ovarian fragments were exposed and cryopreserved in absence or presence of 1.5 M glycerol (GLY), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO), undergoing a previous cooling at 20 °C for 1 h (protocol 1) or at 4 °C for 24 h (protocol 2) in 0.9% saline solution. At the end of each treatment, preantral follicles were classified as non-viable/viable when they were stained/not stained with trypan blue, respectively. To confirm viability staining, ultra-structure of the follicles was evaluated by transmission electronic microscopy (TEM). Data were compared by Chi-square test (P < 0.05). The storage of the ovaries at 20 °C for 1 h (78%) and 4 °C for 24 h (80%) did not reduce significantly the percentage of viable preantral follicles when compared to the control (75%). Similar results were obtained when ovarian fragments, respectively, for protocols 1 and 2, were exposed to MEM (78 and 77%), 1.5 M EG (78 and 71%), as well as frozen in 1.5 M EG (74 and 77%). Percentages of viable follicles in control were similar to those observed after exposure (75%) and freezing (76%) in presence of 1.5 M DMSO only when protocol 1 was used. The increase of the concentration from 1.5 to 3.0 M, for all cryoprotectants, reduced significantly the percentage of viable preantral follicles after freezing. Ultra-structural analysis has confirmed trypan blue results, showing that not only basement membrane, but also organelles, were intact in viable preantral follicles. In conclusion, ovarian tissue cooling at 4 °C for 24 h before cryopreservation (protocol 2) does not affect the viability of bovine preantral follicles when 1.5 M EG is present in the cryopreservation medium

Toxicity test and cryopreservation of sheep isolated preantral follicles using glycerol, ethylen glycol, dimethil sulfoxyde and propanediol

O objetivo deste estudo foi avaliar folículos pré-antrais (FOPA) ovinos isolados após sua exposição e criopreservação utilizando glicerol (GLI), etilenoglicol (EG), propanodiol (PROH) ou dimetilsulfóxido (DMSO) a 1,5 e 3,0 M. Cada par ovariano de 5 ovelhas sem raça definida foi coletado em abatedouro local e submetido ao isolamento folicular. Da suspensão obtida, uma alíquota foi imediatamente destinada à análise da viabilidade folicular com o auxílio do corante vital azul de trypan. O restante da suspensão foi dividida em 16 alíquotas de 0,9 mL, suspensas (v/v) em MEM+ com EG, DMSO, GLI ou PROH a 1,5 ou 3,0 M, para teste de toxicidade e criopreservação. Após o término de cada tratamento, a viabilidade folicular foi analisada e os FOPA considerados viáveis se não corados ou não viáveis, quando corados. A análise dos dados mostrou que após o teste de toxicidade e criopreservação, em todos os crioprotetores e em ambas as concentrações, a percentagem de FOPA viáveis foi significativamente reduzida quando comparada ao controle. No teste de toxicidade, quando os crioprotetores foram comparados entre si nas mesmas concentrações, foram observadas percentagens significativamente menores de FOPA viáveis no PROH 3,0 M (38,9%), apresentando-se, portanto, mais tóxico quando comparado aos demais crioprotetores. Após criopreservação, obteve-se percentagens significativamente maiores de folículos pré-antrais viáveis quando o EG e o DMSO foram utilizados. Em conclusão, FOPA ovinos isolados podem ser criopreservados com sucesso utilizando-se DMSO e EG a 1,5 e 3,0 M.The aim of this study was to evaluate isolated sheep preantral follicles (PF) after exposure and cryopreservation using glycerol (GLI), ethylene glycol (EG), propanediol (PROH) or dimethyl sulfoxide (DMSO) at 1.5 and 3.0 M. Each ovarian pair from 5 mixed breed adult sheeps was obtained at a local slaughterhouse and submited to follicular isolation. From the obtained suspension, one aliquot was immediately analysed with trypan blue. The remaining suspension was divided in 16 aliquots of 0.9 mL, suspended in (v/v) in MEM+ with EG, DMSO, GLI or PROH at 1.5 or 3.0 M to the toxicity test and cryopreservation. After the end of each treatment, the follicular viability was analysed and the PF were classified as viable if not dyed or not viable if dyed with trypan blue. The analysis of the results showed that after the toxicity test and cryopreservation, using all cryoprotectants and at both concentrations, the percentage of viable PF was significantly reduced when compared to the control. At the toxicity test, when the cryoprotectants were compared at the same concentrations, the lowest percentage of viable preantral follicles was obtained when 3.0 M PROH (38,9%) was used, being, more toxic when compared to the others cryoprotectants. After cryopreservation, significantly higher percentual of viable PF was observed when the EG and DMSO were used. In conclusion, sheep PF can be cryopreserved successfully using DMSO and EG at 1.5 and 3.0 M

Global, regional, and national age-sex-specific mortality for 282 causes of death in 195 countries and territories, 1980-2017 : a systematic analysis for the Global Burden of Disease Study 2017

Background Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. Here we report an update to that study, making use of newly available data and improved methods. GBD 2017 provides a comprehensive assessment of cause-specific mortality for 282 causes in 195 countries and territories from 1980 to 2017. Methods The causes of death database is composed of vital registration (VR), verbal autopsy (VA), registry, survey, police, and surveillance data. GBD 2017 added ten VA studies, 127 country-years of VR data, 502 cancer-registry country-years, and an additional surveillance country-year. Expansions of the GBD cause of death hierarchy resulted in 18 additional causes estimated for GBD 2017. Newly available data led to subnational estimates for five additional countries Ethiopia, Iran, New Zealand, Norway, and Russia. Deaths assigned International Classification of Diseases (ICD) codes for non-specific, implausible, or intermediate causes of death were reassigned to underlying causes by redistribution algorithms that were incorporated into uncertainty estimation. We used statistical modelling tools developed for GBD, including the Cause of Death Ensemble model (CODErn), to generate cause fractions and cause specific death rates for each location, year, age, and sex. Instead of using UN estimates as in previous versions, GBD 2017 independently estimated population size and fertility rate for all locations. Years of life lost (YLLs) were then calculated as the sum of each death multiplied by the standard life expectancy at each age. All rates reported here are age-standardised. Findings At the broadest grouping of causes of death (Level 1), non-communicable diseases (NC Ds) comprised the greatest fraction of deaths, contributing to 73.4% (95% uncertainty interval [UI] 72.5-74.1) of total deaths in 2017, while communicable, maternal, neonatal, and nutritional (CMNN) causes accounted for 186% (17.9-19.6), and injuries 8.0% (7.7-8.2). Total numbers of deaths from NCD causes increased from 2007 to 2017 by 22.7% (21.5-23.9), representing an additional 7.61 million (7. 20-8.01) deaths estimated in 2017 versus 2007. The death rate from NCDs decreased globally by 7.9% (7.08.8). The number of deaths for CMNN causes decreased by 222% (20.0-24.0) and the death rate by 31.8% (30.1-33.3). Total deaths from injuries increased by 2.3% (0-5-4-0) between 2007 and 2017, and the death rate from injuries decreased by 13.7% (12.2-15.1) to 57.9 deaths (55.9-59.2) per 100 000 in 2017. Deaths from substance use disorders also increased, rising from 284 000 deaths (268 000-289 000) globally in 2007 to 352 000 (334 000-363 000) in 2017. Between 2007 and 2017, total deaths from conflict and terrorism increased by 118.0% (88.8-148.6). A greater reduction in total deaths and death rates was observed for some CMNN causes among children younger than 5 years than for older adults, such as a 36.4% (32.2-40.6) reduction in deaths from lower respiratory infections for children younger than 5 years compared with a 33.6% (31.2-36.1) increase in adults older than 70 years. Globally, the number of deaths was greater for men than for women at most ages in 2017, except at ages older than 85 years. Trends in global YLLs reflect an epidemiological transition, with decreases in total YLLs from enteric infections, respirator}, infections and tuberculosis, and maternal and neonatal disorders between 1990 and 2017; these were generally greater in magnitude at the lowest levels of the Socio-demographic Index (SDI). At the same time, there were large increases in YLLs from neoplasms and cardiovascular diseases. YLL rates decreased across the five leading Level 2 causes in all SDI quintiles. The leading causes of YLLs in 1990 neonatal disorders, lower respiratory infections, and diarrhoeal diseases were ranked second, fourth, and fifth, in 2017. Meanwhile, estimated YLLs increased for ischaemic heart disease (ranked first in 2017) and stroke (ranked third), even though YLL rates decreased. Population growth contributed to increased total deaths across the 20 leading Level 2 causes of mortality between 2007 and 2017. Decreases in the cause-specific mortality rate reduced the effect of population growth for all but three causes: substance use disorders, neurological disorders, and skin and subcutaneous diseases. Interpretation Improvements in global health have been unevenly distributed among populations. Deaths due to injuries, substance use disorders, armed conflict and terrorism, neoplasms, and cardiovascular disease are expanding threats to global health. For causes of death such as lower respiratory and enteric infections, more rapid progress occurred for children than for the oldest adults, and there is continuing disparity in mortality rates by sex across age groups. Reductions in the death rate of some common diseases are themselves slowing or have ceased, primarily for NCDs, and the death rate for selected causes has increased in the past decade.
