Avaliação de implementação da Educação Superior a Distância: o caso da Secretaria de Educação a Distância da Universidade Federal do Rio Grande do Norte SEDIS/UFRN

The considerable expansion of Distance Education registered in recent years in Brazil raises the importance of debate about how the implementation of this policy has been happening so that formulators and implementers make better informed decisions, maximizing results, identifying successes and overcoming bottlenecks. This study aims to evaluate the implementation process of Distance Education policy by Secretary of Distance Education of the Federal University of Rio Grande do Norte. For this, we sought to use an evaluation proposal consistent with this policy, and came to the one developed by Sonia Draibe (2001), which suggests an analysis called anatomy of evaluation general process. To achieve the objectives, we made a qualitative research, case study type, using documentary research and semi-structured interviews with three groups of subjects who belong to the policy: managers, technicians and beneficiaries. It was concluded that: the implementation process needs a open contact channel between the management and technicians and beneficiaries; the lack of clarity in the dissemination of information between technicians produces noises that affects the outcomes; the absence of dissemination of internal and external actions contributes to the perpetuation of prejudice in relation to Distance Education; using selection criteria based on competence and merit contributes to form a team of skilled technicians to perform their function within the policy; an institution that do not enable technicians generates gaps that possibly will turn into policy implementation failures; all subjects involved in politics need internal evaluations to contribute to improvements in the implementation process, however, a gap is opened between the subjects if there is no socialization of results; the existence of an internal structure that manipulates financial resources and balances the budget from different maintainer programs is essencial; the consortium between IES and municipalities in presential support poles are bottlenecks in the process, since beneficiaries are exposed to inconsistency and lack of commitment of these local municipalities

Diagnóstico do usuário no aprimoramento dos serviços de tecnologia da informação: um projeto de intervenção para o Ministério Público do Estado do Rio Grande do Norte

The information tecnology (IT) has, over the years, gaining prominence as a strategic element and competitive edge in organizations, public or private. In the judiciary, with the implementation of actions related to Judiciário Eletrônico, information technology (IT), definitely earns its status as a strategic element and significantly raises the level of dependence of the organs of their services and products. Increasingly, the quality of services provided by IT has direct impact on the quality of services provided by the agency as a whole. The Ministério Público do Estado do Rio Grande do Norte (MPRN) deployments shares of Electronic Government, along with an administrative reform, beyond these issues raised, caused a large increase in institutional demand for products and services provided by the Diretoria de Tecnologia da Informação (DTI), a sector responsible for the provision of IT services. Taking as starting point strategic goal set by MPRN to reach a 85% level of user satisfaction in four years, we seek to propose a method that assists in meeting the goal, respecting the capacity constraints of the IT sector. To achieve the proposed objective, we conducted a work in two distinct and complementary stages. In the first step we conducted a case study in MPRN, in which, through an internal and external diagnosis of DTI, accomplished by an action of internal consulting and one research of the user satisfaction, we seek to identify opportunities of change seeking to raise the quality perceived of the services provided by the DTI , from the viewpoint of their customers. The situational report, drawn from the data collected, fostered changes in DTI, which were then evaluated with the managers. In the second stage, with the results obtained in the initial process, empirical observation, evaluation of side projects of quality improvement in the sector, and validation with the managers, of the initial model, we developed an improved process, gazing beyond the identification of gaps in service a strategy for the selection of best management practices and deployment of these, in a incremental and adaptive way, allowing the application of the process in organs with little staff allocated to the provision of information technology services

Utilização de bagaço de caju desidratado e complexo enzimático na ração para codornas japonesas em postura

Given the significant share of food costs of poultry production, it is necessary to use strategies and techniques to maximize the utilization and biological value of the components of the diets, keeping constant or improving animal performance. In this context, seeking partial substitution of corn and the best use of the constituents of the diet, the present study aimed to evaluate the effects of inclusion of cashew pomace dehydrated (BCD) and enzyme complex (EC) in the diet on performance and quality eggs of Japanese quails. A total of 200 Japanese quail at 87 days of age, in 25 cages in a completely randomized design in a factorial 2 x 2 + 1 (two levels of cashew bagasse x two levels of enzymes) + control diet without cashew bagasse totaling five treatments with five replicates of eight birds each repetition. The experiment lasted 84 days, divided into four periods of 21 days. The treatments consisted of T1-Ration Control, T2-ration with 7.5% without EC BCD, T3-ration with 7.5% BCD with CE, T4-Ration with 15% BCD without EC and T5-Feed with 15% of BCD with EC. The enzyme complex (EC) is used fermentation product of Aspergillus niger, and cashew bagasse was obtained from the juice industry, passed through drying and crushing process for producing the bran. The performance and egg quality of quails, and performance variables: feed intake (FI), feed conversion ratio per dozen eggs (CAKDZ) and egg mass (CAMO), egg production (OP% bird / day), average egg weight (PMO) and egg mass (MO), and variables were egg quality, specific gravity (SG), Haugh unit (HU), yolk index, and the relationships between components eggs (%albumen,% yolk and %shell). Data were analyzed with the Statistical SAEG (2007). The 7.5 and 15% of cashew bagasse, independent of the enzyme complex decreased feed intake and improved the average egg weight. The two levels with the addition of EC showed significant differences for feed conversion by egg mass. The 7.5 with the addition of enzyme complex obtained the lowest average feed conversion per dozen eggs. The inclusion of up to 15% of cashew bagasse dehydrated with or without addition of enzyme complex in the diet of Japanese quails not interfere in the internal and external quality of eggs. The 7.5 and 15% BCD without added enzyme complex gave better means for specific gravity. Under conditions in which the experiment was conducted, it can be stated that the inclusion of up to 15% of cashew bagasse dehydrated with added enzyme complex feeding quail is economically viable, with the level of 7.5% with the addition of complex enzyme presented the best economic indices

Violência nas escolas: Um novo olhar ante as relações sociais

The most varied ways of manifestation of the violence phenomenon in the contemporary society are each time more found in the media spaces and among society discussions. It makes think about procedures to be taken before the growth and new outbreaks of such phenomenon. The violences manifestations in schools reveal themselves as a reflection of what happens in the scope of social violence. Its dynamics originates in society and reflects itself in scholl, that is, the violences in schools combine internal and external elements to school enviroment of many fields and spheres of which the individuals participate. To reflect about the violences in the schools requires, over all, to make a bridge with the categories: youth and violence. Violences in schools: A new look to the social relations, is a Ms. Sc. Dissertation that has as main objective: to analyze the main existing forms of violence in the school space. For its achievement, it was made a bibliographical survey, questionnaires application (annexed) and observation. Thus, this research articulated the two approaches: qualitative and quantitative. The questionnaires application happened in a state school of the Natal city and amongst yhe criteria for this choice there was the fact of the school had more than 500 pupils, to be located on a strategical place of the city, providing a subjects heterogeneity to be researched, deyond the limitations of available resources financial and material and the available time for the research accomplishment. The scool congregates objective conditions, specifically in what concerns the criteria previously defined: age range, socioenomical level and number of pupils. Amongst the main results obtained, it can be detached that the violence is a phenomenon seen, for the great majority of the research subjects, as a phenomenon connected to the most visible violence forms: the agressions. And a question always present in the public education institutions: infrastructures precariousness, high scool evasion índex and vulnerability among the pupils that makes possible to the pupil to see school as an home extension. Such dissertation concludes that the phenomenon of the violence in scools demands and requires of the most varied subjects involved in the processes na understanding of its determinants so that thus, one can intervene in such phenomenon that does not restrains itself to the physical acts of aggression, but that it is, over all, on a non respecting the different

Características físicas e químicas de frutos de maracujazeiro-amarelo enxertado em três porta-enxertos

O mercado de frutas frescas do maracujá-amarelo valoriza a qualidade interna e externa dos frutos. Assim, este trabalho teve o objetivo de avaliar o efeito do porta-enxerto e do tipo de enxertia na qualidade dos frutos de maracujazeiro-amarelo (Passiflora edulis Sims). O experimento foi conduzido no município de Adamantina-SP, no período de abril de 2006 a junho de 2007, adotando-se o delineamento em blocos ao acaso, em esquema fatorial 3 x 2 + 1 tratamento adicional, com quatro repetições. Os porta-enxertos avaliados foram: P. edulis (maracujá-amarelo), P. alata (maracujá-doce) e P. gibertii (maracujá-giberti), em dois tipos de enxertia: hipocotiledonar e convencional por garfagem tipo fenda cheia e um tratamento adicional, sem enxertia. Utilizou-se como copa o maracujazeiro-amarelo (Passiflora edulis Sims). Avaliaram-se o comprimento, o diâmetro, a massa fresca e a classificação dos frutos no período de novembro de 2006 a abril de 2007, a massa e a espessura da casca dos frutos, o rendimento do suco, o teor de sólidos solúveis totais (SST), a acidez total titulável (ATT) e o ratio (SST/ATT) dos frutos no mês de dezembro de 2006. O diâmetro e a massa fresca de frutos obtidos de plantas enxertadas sobre P. gibertii foram inferiores em relação aos de plantas pé-franco e aos de plantas enxertadas sobre P. alata. Os maiores comprimentos de frutos foram encontrados em plantas não enxertadas. Os porta-enxertos utilizados não influenciaram no teor de SST, na ATT e no ratio. O método de enxertia não interfere no diâmetro, no comprimento, na massa fresca dos frutos, na massa e na espessura da casca, no rendimento do suco e no teor de SST.

Modified 'Stent-Graft Sandwich' Technique for Treatment of Isolated Common Iliac Artery Aneurysm in Patient With Marfan Syndrome

Isolated iliac artery aneurysms are rare in the general population (0.03%) and represent 2% of all abdominal aneurysms, and the association with Marfan syndrome is even rarer. We report a Marfan syndrome case with an isolated common iliac artery aneurysm treated by using a modified 'stent-graft sandwich' technique, with preservation of the internal iliac artery perfusion. The modified 'stent-graft sandwich' technique involves building an appropriate proximal neck just in the common iliac artery for fittingly housing two new stent-grafts inside, both deployed simultaneously and each one going to both distal iliac arteries (internal and external).

Proposta metodológica para o imageamento digital e modelagem virtual 3d de um bloco de rochas travertinas

In this paper we present the methodological procedures involved in the digital imaging in mesoscale of a block of travertines rock of quaternary age, originating from the city of Acquasanta, located in the Apennines, Italy. This rocky block, called T-Block, was stored in the courtyard of the Laboratório Experimental Petróleo "Kelsen Valente" (LabPetro), of Universidade Estadual de Campinas (UNICAMP), so that from it were performed Scientific studies, mainly for research groups universities and research centers working in brazilian areas of reservoir characterization and 3D digital imaging. The purpose of this work is the development of a Model Solid Digital, from the use of non-invasive techniques of digital 3D imaging of internal and external surfaces of the T-Block. For the imaging of the external surfaces technology has been used LIDAR (Light Detection and Range) and the imaging surface Interior was done using Ground Penetrating Radar (GPR), moreover, profiles were obtained with a Gamma Ray Gamae-spectômetro laptop. The goal of 3D digital imaging involved the identification and parameterization of surface geological and sedimentary facies that could represent heterogeneities depositional mesoscale, based on study of a block rocky with dimensions of approximately 1.60 m x 1.60 m x 2.70 m. The data acquired by means of terrestrial laser scanner made available georeferenced spatial information of the surface of the block (X, Y, Z), and varying the intensity values of the return laser beam and high resolution RGB data (3 mm x 3 mm), total points acquired 28,505,106. This information was used as an aid in the interpretation of radargrams and are ready to be displayed in rooms virtual reality. With the GPR was obtained 15 profiles of 2.3 m and 2 3D grids, each with 24 sections horizontal of 1.3 and 14 m vertical sections of 2.3 m, both the Antenna 900 MHz to about 2600 MHz antenna. Finally, the use of GPR associated with Laser Scanner enabled the identification and 3D mapping of 3 different radarfácies which were correlated with three sedimentary facies as had been defined at the outset. The 6 profiles showed gamma a low amplitude variation in the values of radioactivity. This is likely due to the fact of the sedimentary layers profiled have the same mineralogical composition, being composed by carbonate sediments, with no clay in siliciclastic pellitic layers or other mineral carrier elements radioactive

O território das novas economias e suas implicações socioambientais na comunidade pesqueira de Barra do Cunhaú

This dissertation aims to analyze the territory of the new economies and their social implications in the district of Barra do Cunhaú / Canguaretama. We used techniques of qualitative research (document analysis, interviews and observations in situ). It was found that the changes occurring in the territory are linked to the pressures caused by factors internal and external orders, such as the deployment and expansion of projects for development of tourism and shrimp in place, which led to the advancement of real estate speculation and intensification of the deforestation of areas of mangroves along the estuary of the river Curimataú / Cunhaú, contributing to the abandonment of fishing and agriculture for livelihood in this community, therefore, the loss of traditional knowledge applied in the conduct of this activity. It was also found that changes in the use of territory and resources threaten biodiversity and have contributed to the reduction of fish stocks of the Municipality of Canguaretama and thus bar the Cunhaú, especially the stock of crab, Uca (ucides cardatus ). The results indicated that the production in large scale in a market economy, as is the shrimp, ignores the search for balance in regional settings. Thus the environmental disturbances resulting from the shrimp and tourism have consequences for social and cultural aspects, directly affecting the livelihood of the residents of Barra do Cunhaú. Companies of shrimp and related to tourism have absorbed the fishermen who are leaving the fishing activity. However, the low level of education associated with age are factors that make them far outside the framework of employees of these companies. Therefore, it is necessary to create conditions that allow the development of the shrimp and tourism without putting at risk the sustainability of the region

Emetofobia: revisão crítica sobre um transtorno pouco estudado

INTRODUÇÃO: A emetofobia ou fobia de vômitos - que inclui o medo excessivo de vomitar ou de ver outras pessoas vomitando e pode ser desencadeado por estímulos internos e externos - é um transtorno mental complexo e pouco conhecido. OBJETIVO: Este estudo teve como objetivo levantar os conhecimentos disponíveis sobre diversos aspectos do quadro. MÉTODO: Revisão convencional da literatura dos últimos 30 anos utilizando como estratégia de busca as seguintes palavras-chave: emetofobia, emetofóbico, medo de vomitar, fobia de vomitar efobia de vômito. Foram incluídos artigos sobre epidemiologia, fenomenologia, diagnóstico diferencial e tratamento da emetofobia, assim como artigos referidos nestes. RESULTADOS: Não há dados de prevalência na população geral e pouco se sabe sobre a etiologia da emetofobia. A maioria dos estudos aponta predominância no sexo feminino, início precoce e curso crônico. Os comportamentos de esquiva podem impactar negativamente a vida ocupacional, social e familiar. Os principais diagnósticos diferenciais são: transtorno de pânico com agorafobia, fobia social, anorexia nervosa e transtorno obsessivo-compulsivo. Estudos de tratamento se resumem a relatos de casos e não há ensaios clínicos controlados, mas intervenções cognitivo-comportamentais parecem ser promissoras. CONCLUSÃO: Mais estudos são necessários para melhor compreensão sobre a epidemiologia, o quadro clínico, a etiologia, a classificação e o tratamento da emetofobia.

Características de carcaça de caprinos de cinco grupos raciais criados em confinamento

Este trabalho foi realizado com o objetivo de avaliar a influência do grupo racial e da condição sexual nas características da carcaça de caprinos jovens criados em confinamento. Foram utilizados 91 animais, 52 machos e 39 fêmeas, pertencentes a cinco grupos raciais: Alpino, ½Boer + ½Alpino, ½Anglo Nubiano + ½Alpino, ¾Boer + ¼Alpino, e ½Anglo Nubiano + ¼Boer + ¼Alpino. Foi tomado o peso ao jejum, no dia do abate, após 24 horas de jejum de sólidos. Foram tomadas medidas biométricas e de carcaça, objetiva e subjetivamente. O grupo racial influenciou a altura de cernelha, o comprimento interno e externo da carcaça e o comprimento de perna, que foram maiores nos animais Alpinos, bem como a largura do peito, o escore corporal, os índices de compacidade da carcaça e da perna e a cobertura de gordura da carcaça, que foram melhores nos animais com grau de sangue Boer. Animais machos tiveram maior altura de cernelha, medidas da estérnebra com ultrassom, comprimento interno da carcaça, comprimento de perna, profundidade dos tecidos na altura da 3ª e 4ª estérnebras tomadas na carcaça. Nas demais características corporais avaliadas, não foram encontradas diferenças entre grupos raciais e sexo dos animais. O cruzamento do grupo Boer com Alpino reduz o comprimento das carcaças e aumenta a cobertura de gordura e a quantidade de tecidos depositados, mas não influencia o desempenho do animal.

Interface entre história da matemática e ensino: uma atividade desenvolvida com base num documento do século XVI

Este artigo propõe a construção de uma interface entre história e ensino de matemática a partir de um diálogo entre historiadores e educadores da matemática. Para tanto, consideramos aspectos epistemológicos e metodológicos ligados à história da matemática, pautada em tendências historiográficas atuais, juntamente com a metodologia baseada no movimento lógico-histórico. A interface contemplou o movimento do pensamento na formação dos conceitos e o contexto no qual tais conceitos foram desenvolvidos, de modo a conduzir à reflexão sobre o processo histórico da construção do conhecimento para a elaboração de atividade didática. Esta atividade teve por base um documento do século XVI dedicado à construção e uso de instrumentos matemáticos, e sua elaboração levou em consideração uma intencionalidade e um plano de ação que viabilizaram o seu desenvolvimento. A organização do ensino articulou as conexões internas e externas trazidas pela análise do documento e a forma do pensamento do desenvolvimento do conceito.

Desempenho de poedeiras alimentadas com rações suplementadas com ácido fumárico

Um experimento foi conduzido com o objetivo de verificar o efeito da adição de ácido fumarico às rações de poedeiras comerciais sobre o desempenho produtivo das aves. Duzentos poedeiras da linhagem Lohmann, com 36 semanas de idade, foram submetidas a um delineamento inteiramente casualizado, com cinco tratamentos, cinco repetições e oito aves por parcela. As aves receberam ração basal acrescidas ou não de ácido fumarico. Os tratamentos consistiram em adicionar 0, 0,25, 0,50, 0,75 e 1,00% de ácido fumárico à dieta basal. Os resultados de desempenho e qualidade interna e externa dos ovos, obtidos durante três ciclos de 28 dias, não apontaram diferenças significativas entre os tratamentos. Estes resultados indicaram que o ácido fumárico não teve efeito como potencializador dos nutrientes, não se justificando sua viabilidade de aplicação nos níveis estudados em rações de poedeiras.
