A Literatura de Cordel como recurso didático na orientação de usuários em uma biblioteca universitária

A Literatura de Cordel consiste numa forma de conhecimento que produz conteúdos importantes para serem inseridos nos mais diversos contextos educacionais. Através de sua linguagem simples, o cordel versa sobre os mais variados temas, proporcionando uma leitura prazerosa. Assim, o objetivo geral desse trabalho é utilizar-se do cordel, com sua característica lúdica, para educar usuários e funcionários de bibliotecas, promovendo um espaço de formadores de habilidades e competências no uso consciente do acervo. A metodologia constou de abordagem aos alunos durante a visita guiada à Biblioteca Central da Universidade Federal do Rio Grande do Norte, onde são prestadas informações dos serviços oferecidos e da importância do acervo de uma biblioteca na sua vida acadêmica, bem como de sua preservação. Ao final da visita, cada aluno recebe um folheto de cordel contendo informações sobre o uso consciente do acervo, além da recomendação de que após a leitura do cordel, o mesmo seja repassado sucessivamente para outros membros da comunidade, de forma a alcançar uma maior parcela de leitores. Os resultados apontam que o cordel destaca-se como um poderoso instrumento didático-pedagógico e disseminador de informações. Ademais, ele tem a facilidade de alcançar desde os mercados e feiras, que divulgam a ciência e a arte, bem como as tradições populares. Conclui-se que o uso do cordel, numa perspectiva educativa, permite transmitir para os usuários de uma biblioteca, bem como à comunidade em geral, as boas maneiras de utilização dos suportes informacionais.

Cordel Informativo: serviços oferecidos aos usuários de uma biblioteca universitária

Na observação prática cotidiana da Biblioteca Central Zila Mamede (BCZM), procurou-se identificar o comportamento dos usuários com relação ao uso das informações disponibilizadas. É bem possível que os usuários não se interessem pelos serviços por não conhecê-los plenamente. Tais observações levaram aos seguintes questionamentos: a) a comunidade acadêmica da Universidade Federal do Rio Grande do Norte (UFRN) sabe da existência de todas as fontes de informação disponibilizadas para pesquisa nessa unidade informacional? b) O desinteresse por algumas dessas fontes de informação tem relação com o desconhecimento das mesmas? Estes questionamentos motivaram a realização de um projeto que tem como objetivo divulgar as formas de acesso à produção científica da UFRN. Esse artigo descreve os serviços oferecidos pela BCZM, através da Literatura de Cordel, com a finalidade de estimular e sensibilizar os alunos de graduação, pós-graduação, professores e funcionários sobre a importância do acesso ao conhecimento científico disponíveis na biblioteca, acredita-se que a Literatura de Cordel, por ser um suporte informacional que alcança desde mercados e feiras, divulga a arte, a ciência e as tradições populares, ajuda, também, na disseminação das informações e estimula o prazer pela leitura. Tais requisitos capacita a nossa Comunidade Acadêmica, bem como o público em geral, o qual terá acesso às informações relevantes que servirão de insumos na construção do conhecimento. Neste artigo, serão apresentados em versos e estrofes escritos em forma rimada, os serviços que a BCZM oferece à sua comunidade. Posteriormente, serão divulgados outros serviços e as formas de acesso à produção científica da UFRN.

Potencial larvicida de extratos de plantas regionais no controle de larvas de Aedes aegypti

Dengue, amongst the virus illnesses one can get by vectorial transmission, is the one that causes more impact in the morbidity and mortality of world s population. The resistance to the insecticides has caused difficulties to control of vector insect (Aedes aegypti) and has stimulated a search for vegetables with larvicidal activity. The biodiversity of Caatinga is barely known and it is potential of use even less. Some plants of this biome are commercialized in free fairs northeast of Brazil, because of its phytotherapics properties. The vegetables in this study had been selected by means of a questionnaire applied between grass salesmen and natives of the Serido region from Rio Grande do Norte state; culicids eggs had been acquired with traps and placed in container with water for the larva birth. Thirty larvae had been used in each group (a group control and five experimental groups), with four repetitions four times. The vegetables had been submitted to the processes of decoction, infusion and maceration in the standard concentration of 100g of the vegetable of study in 1l of H2O and analyzed after ½, 1, 2, 4, 8, 12, 24 and 48 hours for verification of the average lethal dose (LD50) from the groups with thirty larva. The LD50 was analyzed in different concentrations (50g/l, 100g/l, 150g/l, 200g/l e 300g/l) of Aspidosperma pyrifolium Mart. 48 extracts of rind, leaf and stem of the seven vegetal species: Aspidosperma pyrifolium Mart., Mimosa verrucosa Benth, Mimosa hostilis (Mart.) Benth., Myracrodruon urundeuva Allemão, Ximenia americana L, Bumelia sartorum Mart Zizyphus joazeiro Mart, had been analyzed. The extracts proceeding from the three methods were submitted to the freezedrying, to evaluate and to quantify substances extracted in each process. The results had shown that Aspidosperma pyrifolium Mart. and Myracrodruon urundeuva Allemão are the species that are more distinguished as larvicidal after 24 hours of experiment, in all used processes of extraction in the assays. The Zizyphus joazeiro Mart species has not shown larvicidal activity in none of the assays. In relation to the extraction method, the decoction was the most efficient method in the mortality tax of the A. aegypti larvae

Fé & Cia. LTDA: consumo religioso na sociedade contemporânea

The present work is an exercise of analysis from the cultural exercises related to movie high one of its raised status more with the deity, the human being surrenders it Religion leaving puzzleds the prophets of its end. The purpose of this work is to show that the religious phenomenon is one of the essential components of the socialization human being. The religious dimension, although to have been kept out of society in modernity - it was cybernetics, is an indispensable compassing to guide the human being in the discovery of its true existencial direction. For this, to attenuate the legacy without appropriate title, overwhelming and despairing of the producing and consumer goods society, it is indispensable to add as basic part to the practical one of the religion. And this practice is specify at the acquirement as of commodities objects , than it is to they are consecrate, exercising um magical power under the assistants from the religion. The fair religious Expo Religious, like the Expo Crest (fair as of commodities and service of the Evangelist) and the one Expo Catholic (fair as of commodities and service of the Catholics), appears at the I initiate from the century 21 at the association Brazilian about to cater the litigation of the market religious at every their segments. The and objective of this research is bring forward those two fairs in the format as of Expo and your contribution at the dynamic from the religion crest at the association he acts

Direção espiritual na TV canção nova: análise do discurso do Padre Fábio de Melo

The aim of the research is to analyze Direção Espiritual a TV program produced by Catholic Church and presented by Canção Nova Channel. The program is presented by Father Fábio de Melo, a catholic priest that also is a famous religious singer and writer. The analyses included not only some TV programs, but also interviews with some of the viewers and Fabio de Melo himself. The results points out the emergence in Brazil of a new religious speech from Catholic Church founded in comprehension path, dissociated from punishment and guilty. This religious speech is more like a self help speech rather than a tradicional religious discourse itself, very similar to psychotherapeutic speech. The TV program presented by Fabio de Melo is guided in tiny line of sacre and profane which announces contradictions but also a new blend of religious approach in contemporary days

Limites e possibilidades do programa nacional de alimentação escolar enquanto estratégia de promoção da segurança alimentar e nutricional no municipio de Macaíba/RN

This dissertation aims to understand the importance of the National School Feeding as a strategy for ensuring the promotion of food and nutrition security in the municipality of Macaíba / RN, taking into account the implementation of the Law School Feeding, 11,947, 2009. The program was extended to all public basic education, youth and adults, in addition to ensuring that 30% of transfers from FNDE, were intended for the purchase of products from family farms. The survey was conducted with 160 students from public schools and farmers nesting Quilombo dos Palmares II, who produce on their land vegetables, fruits and cereals for their own consumption, for sale in local markets, in addition to providing for PNAE. The reciprocity between neighbors, such as mutual aid and sharing of common goods was noticeable in this group of farmers, since it was necessary to meet weekly deliveries of products to schools. As students, we applied a test of acceptability in two schools located in rural and in urban areas, to learn the opinion of ourselves in relation to school food consumed. It was concluded that to be most effective program in the region, there must be a better match in school menus, so that it can be attractive to students and to ensure greater use of fresh food, the main ingredient of same, practice of nutrition education in schools, to teach students the importance of food to health. In relation to local management, noted the need for adjustments bureaucratic as hiring staff for the departments, in order to be more agile in releasing payments to farmers, in addition to hiring assistants general services for schools, one Since the cooks exert dual role, the cooking while being responsible for cleaning the entire school environment. Government investments in the rural sector would be extremely valuable for farmers, since they need financial resources to purchase inputs, irrigation projects for gardens, availability of land for planting, transportation to facilitate the delivery of its products to schools and technical assistance more frequently

Ação social da Rede Caritas de Empreendimentos de Economia Solidária - EES: um estudo sobre valores e dinheiro

This study seeks to analyze the relationship between values and economic practices in social actions developed by the Caritas Network northeastern in projects linked to the Solidarity Economy over the last decade. This link between economic values and practices is discussed in relation to both Weber (Economy and Society) and Simmel (The Philosophy of Money) with a treatment of the affinities between both the economic sphere and religious ethics and the forms of sociability that bring individuals into contact with the circulation of money. The research scope was comprised of businesses monitored by Caritas in four northeastern states (Pernambuco, Paraíba, Alagoas and Rio Grande do Norte where we sought investigate the influence of ethical values, religious networks, and the economic practices of associations, groups and cooperatives. The field research took place over nine months with visits to local groups in their production areas, participation in trade fairs, training, exchanges, forums and regional meetings. Through this research we saw that money, the symbol and instrument of utilitarian reason, shapes individual behavior and socialization conditions since in business practices it is permeated by religious and ethical values when confronted by their experiences, values and neoliberal practices. The data and conclusions and relates to the overall research of the regional Caritas Network, the place it occupies in the Solidarity Economy and its influence on the sociability of business

Um estudo de estruturas com PBG e fotônica

One of the objectives of this work is the ana1ysis of planar structures using the PBG (photonic Bandgap), a new method of controlling propagation of electromagnetic waves in devices with dielectrics. Here the basic theory of these structures will be presented, as well as applications and determination of certain parameters. In this work the analysis will be performed concerning PBG structures, including the basic theory and applications in planar structures. Considerations are made related to the implementation of devices. Here the TTL (Transverse Transmission Line) method is employed, characterized by the simplicity in the treatment of the equations that govern the propagation of electromagnetic waves in the structure. In this method, the fields in x and z are expressed in function of the fields in the traverse direction y in FTD (Fourier Transform Domain). This method is useful in the determination of the complex propagation constant with application in high frequency and photonics. In this work structures will be approached in micrometric scale operating in frequencies in the range of T erahertz, a first step for operation in the visible spectra. The mathematical basis are approached for the determination of the electromagnetic fields in the structure, based on the method L TT taking into account the dimensions approached in this work. Calculations for the determination of the constant of complex propagation are also carried out. The computational implementation is presented for high frequencies. at the first time the analysis is done with base in open microstrip lines with semiconductor substrate. Finally, considerations are made regarding applications ofthese devices in the area of telecommunications, and suggestions for future

Avaliação econômica das perdas de banana no mercado varejista: um estudo de caso

O objetivo do presente estudo foi a determinação das perdas físicas e econômicas de banana em diferentes equipamentos varejistas na Cidade de Botucatu - SP e suas possíveis causas. Os equipamentos foram sorteados aleatoriamente. As informações foram coletadas através da aplicação de questionário para a determinação das perdas de três variedades de banana. O resultado mostrou perda global de 39 toneladas, correspondente a 11,1% da quantidade comercializada, sendo 10,5% em supermercados, 15,0% em quitandas/sacolões e 10,6% em feiras livres. O valor total das perdas anuais atingiu R$ 35.038,00, em valores de maio de 2002. A manipulação excessiva do cliente, excedente de oferta, uso de embalagem inadequada e baixa qualidade da fruta foram as principais causas de perdas. Conclui-se pela necessidade de conscientização do cliente, do uso de embalagens plásticas e de cuidados no manuseio da fruta durante toda pós-colheita.

Eletrofiação e caracterização de membranas biopoliméricas a base de quitosana extraídas dos exoesqueletos de crustáceos

Chitin and chitosan are nontoxic, biodegradable and biocompatible polymers produced by renewable natural sources with applications in diverse areas such as: agriculture, textile, pharmaceutical, cosmetics and biomaterials, such as gels, films and other polymeric membranes. Both have attracted greater interest of scientists and researchers as functional polymeric materials. In this context, the objective of this study was to take advantage of the waste of shrimp (Litopenaeus vannamei and Aristeus antennatus) and crabs (Ucides cordatus) from fairs, beach huts and restaurant in Natal/RN for the extraction of chitin and chitosan for the production of membranes by electrospinning process. The extraction was made through demineralization, deproteinization, deodorization and deacetylation. Morphological analyzes (SEM and XRD), Thermal analysis (TG and DTG), Spectroscopy in the Region of the Infrared with Transformed of Fourier (FTIR) analysis Calorimetry Differential Scanning (DSC) and mechanical tests for traction were performed. In (XRD) the semicrystalline structure of chitosan can be verified while the chitin had higher crystallinity. In the thermal analysis showed a dehydration process followed by decomposition, with similar behavior of carbonized material. Chitosan showed temperature of maximum degradation lower than chitin. In the analysis by Differential Scanning Calorimetry (DSC) the curves were coherent to the thermal events of the chitosan membranes. The results obtained with (DD) for chitosan extracted from Litopenaeus vannamei and Aristeus antennatus shrimp were (80.36 and 71.00%) and Ucides cordatus crabs was 74.65%. It can be observed that, with 70:30 solutions (v/v) (TFA/DCM), 60 and 90% CH3COOH, occurred better facilitate the formation of membranes, while 100:00 (v/v) (TFA/DCM) had formation of agglomerates. In relation to the monofilaments diameters of the chitosan membranes, it was noted that the capillary-collector distance of 10 cm and tensions of 25 and 30 kV contributed to the reduction of the diameters of membranes. It was found that the Young s modulus decreases with increasing concentration of chitosan in the membranes. 90% CH3COOH contributed to the increase in the deformation resulting in more flexible material. The membranes with 5% chitosan 70:30 (v/v) (TFA/DCM) had higher tensile strength

Diagnóstico regional do processo de queijo coalho comercializado em Natal/RN

Coalho cheese is a typical product of the Northeastern Brazil, which is consumed both raw and cooked. The present work aimed to study the characteristics of artisanal and industrial processes in the production of coalho cheese sold in Natal / RN in order to evaluate its quality and consumer s profile. Four artisanal cheeses plants were monitored and a questionnaire was sent to different cheese industries. Besides this, eight cheese samples (four artisanal and four industrial) were evaluated in regard to the microbiological quality, physical-chemical and sensory attributes. The sensory acceptance was evaluated by using 108 non-trained panelists by using the hedonic scale. The consumer s profile survey was applied to 400 consumers of coalho cheese. The lack of hygiene control was detected at the artisanal cheese production, which uses raw milk as its raw material. Research has shown that the industrialized cheeses are made from pasteurized milk provided by their own production or by a third party, as observed in cheese making dairies. In general, the results indicate variation in the manufacturing process of coalho cheese, which results in the lack of product standardization. Regarding the physical-chemical analysis, most artisanal and industrial samples presented moisture content between 36 and 40 %, classified as medium moisture cheese, which is the only parameter that showed no significant difference (p>0.05). However, the water activity (Aw), pH and acidity results differed significantly. All artisanal samples showed coliform contamination at 35 °C, which confirms the poor hygienic conditions. In regard to coliforms at 45 °C, 75 % of artisanal coalho cheese samples had value higher than 103 MPN / g, a value above the lawful limits determined by RDC nº 12. Fifty percent of industrial coalho cheese samples showed coagulase-positive Staphylococcus values above the limit allowed by the RDC nº 12, indicating poor handling. The sensory evaluation revealed that the taste was the only parameter that showed significant difference, and this difference was only between two industrial brands. The consumer s survey showed that the coalho cheese flavor is the most important reason for buying this kind of cheese. Although coalho cheese is mainly bought in supermarkets, open street markets and country shops are still important selling points. It is concluded that there is no coalho cheese standardization in the RN state, which leads to variations in physical-chemical and sensory attributes. Moreover, it is necessary greater hygiene control in the production and handling procedures of coalho cheese.
