Uso de plantas medicinais em comunidades religiosas no Brasil: conhecimento tradicional & riscos potenciais

O Brasil caracteriza-se pela pluralidade cultural e religiosa. Muitas religiões, como a Umbanda, o Candomblé e o Espiritismo, utilizam plantas em rituais ou com o intuito de combater doenças. No combate das doenças, as plantas medicinais são utilizadas com base no conhecimento tradicional, muitas vezes distorcido pela sociedade moderna. Portanto, há um risco inerente nesta prática, pois o efeito das plantas medicinais está relacionado à presença de substâncias químicas, geralmente metabólitos secundários, as quais exercem ação farmacológica de forma análoga aos fármacos sintéticos, bem como podem produzir reações adversas ou intoxicação. Além disso, o uso adequado das plantas medicinais envolve conhecimento sobre seu cultivo, colheita/coleta, modo de preparo, posologia e indicação. O objetivo deste trabalho foi realizar uma revisão bibliográfica sobre o uso de plantas medicinais por comunidades religiosas e avaliar o risco de sua utilização com base em evidências científicas. Concluiu-se no trabalho que a maioria das plantas utilizadas está de acordo, totalmente, ou em parte com as indicações de uso na medicina popular ou respaldadas por estudos científicos. Porém, algumas das plantas medicinais utilizadas apresentam alta toxicidade e a indicação de uso de algumas outras, não condiz com estudos científicos ou uso na medicina popular

Gêneros do discurso, ciência e mídia: a divulgação científica em questão

This work’s main purpose is to research how the scientific speech is outlined on the Revista Língua Portuguesa in statements made by linguists. Statements issued in the previously mentioned magazine have been analyzed. In order to achieve the proposal, the research was based on the following questions: how both the scientific and the scientific divulgation speeches are formed in the magazine, and whether the opinion texts written by scholars and researchers in the linguistic field identify themselves with opinion articles, scientific articles or scientific divulgation texts. Those questions were discussed from the theoretical-methodological bakhtinian perspective, taking the notion of dialogism, the human activity sphere, genres of discourse and style as conceptual elements. It has been detected that there is a complexity in the construction of the genres in the magazine, always taking into account the journalistic and scientific spheres of circulation. The analyzed statements presented themselves as a confluence of many genres’ characteristics, showing a point of view, a scientific subject, a researcher-author and a language adjustment to the magazine reader, making it more accessible. The analysis showed that the discussed statements resemble opinion articles, scientific articles, and reviews, besides being scientific divulgation at the same time

Avaliação da Taxa de Exposição em Exames Radiológicos Realizados em Procedimentos Cirúrgicos - Minimização dos Riscos em Indivíduos Ocupacionalmente Expostos

This paper consists in the evaluation of the exposure rate to ionizing radiation to which professionals working in surgical procedures which require radiological examinations are subjected. Were initially performed real-time readings of exposure rate within four distinct operating rooms during the execution of four surgical procedures that made use of fluoroscopy equipment (including three orthopedic surgeries, one in the shoulder, one in the arm, another for deployment of metal pin in the leg region, and a fourth for vascular procedure); in these surgeries were used ionization chamber detector and an electrometer. In order to check the values achieved, was made a re-evaluation of the distribution of the rate of exposure to radiation, from the surgical procedures, now with thermoluminescent dosimeters (TLDs). For this, thirty TLDs were distributed in the operating rooms, arranged in points of interest as occupation by professionals. The TLDs were prepared for thirty consecutive days, after which they were removed and replaced with new dosimeters not exposed yet. The dosimeters were subjected to reading of the rate of exposure; this procedure was repeated for four months without interruption. The quantification of the results sought primarily to convert the rate of exposure for equivalent dose rate, both in measurements with ionization chamber as in measurements with TLDs, in order to highlight the presence of the biological effect of ionizing radiation for comparisons within scientific context. Then, the results were plotted to establish the relationship between the values of equivalent dose and the distance to the central axis of the x -ray source, confirming the inverse square law for distance. Finally, the values were associated with the maximum limit recommended by the legislation for occupationally exposed individuals. The methodology for the analysis and quantification of the data in this work aims at implementing a work plan that meets ...

A divulgação do pensamento saussuriano no Brasil

The ideas of Ferdinand de Saussure (1857-1913) still stimulate keen interest among language scholars today, be it complementary or contradictory. Saussurean thought has become widespread, in a more or less explicit manner, in undergraduate and graduate education in the humanities. Since the mid-1950s, Saussure’s ideas have been introduced and debated as part of the training of first-language and foreign-language teachers, communicators, anthropologists, sociologists and psychologists. In the majority of undergraduate and graduate disciplines in the areas of Linguistics and Communication, from the moment academics begin to address the nature of human signification and communication, it is impossible to ignore Saussure’s reflections on language and parole. The aim of this study is to reflect on the transmission of the general lines of Saussurean thought in Brazil. For this purpose, an inventory and analysis are carried out of Linguistics manuals originally published in Brazil since the 1970s, with the aim of reflecting on their construction in terms of programming and persuasion, categories of analysis of didactic speech proposed by A. J. Greimas.

Obesidade infantil: etiologia, consequências e formas de intervenção

Obesity is defined as excess body fat. It is considered today a serious public health problem and has reached high proportions in childhood and adolescence. Among factors highlight the lifestyle, poor diet and little physical activity for their development. Childhood obesity is not treated can become permanent in adulthood increases the risk of several diseases such as cardiovascular, metabolic and other disorders such as depression, low self-esteem among others. It's extreme need multidisciplinary intervention to prevent it, with guidelines on healthy eating habits and regular physical activity. Treatment is necessary in a multidisciplinary team of doctors, nutritionists, physical educators, psychologists and family that has a decisive weight in the treatment of obese children. The media could give more space for the disclosure of childhood obesity, so that the population is aware of this epidemic in a more serious understand its risks and health effects. This bibliographic study has character and aims to seek the causes of obesity, its consequences in adulthood and possible forms of intervention

Construção de instrumentos técnicos de astronomia para a divulgação científica: telescópio fotométrico de grande abertura e baixo custo

Although the popularization of astronomy in the last decade and the International Year of Astronomy, celebrated in 2009, there's a great lack in respect of quality instruments for astronomical disclosure. Thinking in this research about it, we intend to recuperate and elucidate a technique long forgotten: the metal mirror amateur telescope, once was done in the first reflecting telescopes. However, with the resources available today and given the high purity of the materials, our results were better than that obtained by the pioneers. We developed and built a large aperture telescope (250 mm diameter) and very bright (focal ratio = 4.0), versatile and portable. In our study was described step by step the process to fabricate the telescope. Through its first images captured of the Moon, we can illustrate its versatility both for use in outreach events and for use in amateur astronomy, because it is a primary focus capture system and can run registration of various astronomical events

En este trabajo se propone una secuencia de actividad laboral (gimnasia) en el intervalo de tiempo pequeño, respetando las instalaciones y el espacio físico disponible en el ambiente del trabajo, como una estrategia para mejorar la calidad de vida laboral, para aumentar la productividad, mejorar la disposición a trabajar y para aumentar el conocimiento del cuerpo y de la interacción social.

Elementos sociais para a compreensão do prestígio científico e de seus riscos

Natural sciences have an enormous status in public opinion. Their achievements, which become known mostly by means of technology, give to them social credibility, unconditional support and positive social expectances. Further, their social images, generated by the success of their products, tend to lead people to develop only favorable ideas about scientists and about how science works, which are even more reinforced in the schools. By another side, the history of science has been allowed us to comprehend the internal and external social relations concerning to science, showing it as a field of disputes, interests and contradictions as many other fields which comprise human relations. Therefore, the objective of this text is to present social elements of the construction and impacts of natural science, aiming at putting in evidence the importance of the social studies of the scientific world for the courses of education of science teachers.
