A interação nas distâncias: a análise de um processo

Education and technology have always walked side by side. The Information and Communication Technologies are inserted in education as a profile of people from the new era. This research has the objective of understanding the insertion of the use of the Technologies of Information and Communication within the educational context, from the analysis of the process of interactivity among students and teachers of the Portuguese distance course of the Tiradentes University (Unit). For such, the empiric investigation was based on the analysis of academic documents, such as: the Course Pedagogical Project and Class Planning of regular classes, in regular classrooms, as well as interviews, focal groups, and pictures with people who live the history of the course. Direct observations were also conducted. The methodology applied was bibliographic and qualitative research of the exploratory type, using the information that was collected through the interviews. The results of this research demonstrated that the interaction promoted by the ICT represents a process of social change, and therefore, of development for education. It was concluded that the Distance Education has to overcome some fragilities, aiming at contributing to the educational field and to the promotion of interactions among students

The object of this study is the organizational management, particularly the relational processenvironment organization focused on the survival of the space Department of the Arts and Crafts Mestre Raimundo Cardoso linked to the structural arrangement of the Liceu do Paracuri.. Aimed to understand the ways of organizational survival, from the actors' perception of the Center for Arts Career Workshops and Lais Aderne, with investments that discuss the theoretical models of management, institutional theory, cultural organization and institutionalization of public education requirement of the municipal light LDB. (1996) used a qualitative approach with a view to RICHARDSON (1985). The data generated were analyzed based on the technique of content analysis, the thematic type [categorical] Bardin (1977). The results indicate that the institutionalization of the arrangement of the Liceu do Paracuri emerges meet the legal requirement of the autonomy of municipal educational administration under the aegis of sustainable development, quality of life and basic education from the municipal Hélio Gueiros (1993-1996 ). More specifically the Center for Arts and Crafts Laís Aderne, the unit of analysis, the subjects said that this space is designed as a link between the demands of school and community searching through interdisciplinary activities educate and train manpower mainly potter. They did mention the existence of institutional factors (history, culture, habits, values) represent a strong socio-cultural element to the actors belonging to the core that guides behavior and actions of these individuals, fueled by a sense of hope, inclusion of future artisans in culture ceramist. It made a shared management, the existence of a unique work through cultural revival. However, over the course of time, the core is faced with dilemmas of managing transitions mainly regarding governmental, technological beyond endurance by the craftsmen for the optimization of their work. The conclusion - that the paths chosen for the organizational survival of the core meaning and guiding their actions in the systematization of conduct, representations, memories and traditions through habits and choices of consensus, the viewpoint of the actors

O Litoral e a metrópole dinâmica imobiliária, turismo e expansão urbana na região metropolitana de Natal-RN

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

Plano setorial: a construção de estratégias para implementação do plano diretor de Natal

The Sectoral Plan was inserted as an urban instrument in Master Plan of Natal (LC82/07), since then it has been deepened. It is guided to the equitable distribution of the benefits of urbanization, aimed the efetivation of the Right to the City and the Environmental function of property in the context of urban planning. Thereby, the Sectoral Plan was inserted into the perspective of promoting a favorable field for applying articulated of instruments defined in the Master Plan, and them with urban interventions, through the deepening of macrozoning - coming out of dimension of the city and going to a small fraction of the urban by reducing scaling - facilitating democratic management in accordance with the City Statute. However, the absence of regulation and the conceptual and operational fragility of the instrument, approached it of other existent experiences and instruments, limiting its application and evaluation. Considering the innovative nature of the instrument and the intense social participation, we inquire about conceptual and operational elements which could give greater effectiveness to Sector Plan in construction? Guided by that question, this dissertation aim to understand the nature and operational procedures of Sectoral Plan, seeking to do indications about the conceptual and operational aspects of implementing a Sector Plan. The neighborhood of Ponta Negra was selected as empirical universe because it was the first sector defined in the Master Plan. This research adopts reference authors who´s make reflection and insights about the matrix of Urban Reform, whose principles constitute the basis of the trajectory of revision of urban planning in Brazil since the 1980s, highlighting Raquel Rolnik, Nelson Saule Júnior and Orlando Alves dos Santos Júnior. For the local monitoring, we use the authors Alexsandro Ferreira Cardoso Silva, Rosa Maria Pinheiro Oliveira e Marise Costa da Souza Duarte, in order to understand the growth dynamics of Natal, lawfully and urbanistically

Obtenção de polímeros de LCC para aplicação como antioxidante de biodiesel de soja

Biodiesel is a fuel obtained from vegetable oils, such as soy, castorbean, among others. The monoester of fatty acid of these oils have chains with mono, di and tri double connections. The presence of these insaturations are susceptible to oxidization. Antioxidants are substances able to prevent oxidization from oils, fats, fat foods, as well as esters of Alquila( biodiesel). The objective of this work is to summarize a new antioxidant from the Cashew Nut Shell Liquid (CNSL) using the electrolysis technique. A current of 2 amperes was used in a single cell of only one group and two eletrodos of stainless steel 304 in a solution of methanol, together with the eletrolits: acetic acid, sodium chloride and sodium hydroxide, for two hours of agitation. The electrolysis products are characterized by the techniques of cromatography in a thin layer, spectroscopy of infrared and gravimetric analysis. The material was submitted to tests of oxidative stability made by the techniques of spectropy of impendancy and Rancimat (EN 14112). The analyses of characterization suggest that the polimerization of the electrolytic material ocurred. The application results of these materials as antioxidants of soy biodiesel showed that the order of the oxidative stability was obtained by both techniques used

Auta de Souza, a poeta de pele clara, um moreno doce : memória e cultura da intelectualidade afrodescendente no Rio Grande do Norte

In the first half of the twentieth century different groups of intellectuals were engaged in the pursuit of an ideal of Brazility. Thereon, two currents are perceived. The first was marked by a nostalgic bias about the past, being formulated by intellectuals from the region that was turning as Northeast. This group of intellectuals emphasized values and traditions of the agrarian aristocracy of the region that was losing visibility in the political and economic Brazil scene. Already the other current has a more modern and industrial feature, was formed by intellectuals from the Southeast that in detriment of the first, was rising. This group, on the other hand, was intended to give a new face to Brazil and break with the "roots" of our delay that in their view were linked to our agrarian past. This resulted in different perceptions and interpretations of our historical past, and the construction of different profiles to the Brazilian. Accordingly, our work seeks to understand how was produced the writing that silenced the mixed ancestry of Auta de Souza (1876-1901) considering the position that she should occupy in the intellectuals projects who were in charge of forming a memory for our state. Auta as a relevant historical character in this project of potiguares intellectuals, she was raised to the condition of a model woman and elected in the pantheon of the most beloved poets of Rio Grande do Norte, however, to occupy such prestigious position she had her racial ancestry concealed in the writings that these same intellectuals had written about her, what is still spreaded in memory and rituals places of religious and civic features

ELOY DE SOUZA: UMA INTERPRETAÇÃO SOBRE O NORDESTE E OS DILEMAS DAS SECAS

The thought of Eloy de Souza is studied (1873-1959), that left a significant intellectual production in the journalistic, cultural and politicial scope on the Northeast and the dilemmas of the droughts. Through the method of content analysis, his journalistic and literary speech is investigated, looking at to understand the elaboration and/ or reiteration of categories, of representations and of values; it is verified how was conceived the constitution of the political thought and which is it´s principal slopes; the parliamentary speech, present in his interventions is analyzed in plenary session, participation in commissions and in his projects, particularly in the thematic area of the droughts. It is verified that his work is built in a political and ideological perspective inserting the bourgeoisie landowner's interests and Northeastern commercial and of it´s political strata, inside the historical block of agro-industry power that has as irradiation focus the area of the coffee represented politically by the oligarchies person from São Paulo and Minas Gerais. In that sense, two crucial categories emerge: the droughts and the country, as the Northeastern and Brazilian man's synthesis, with their resistance capacity and adaptation, and their creative effort in an adverse enviroment, that Eloy de Souza started to insert in his political speech. However, the vision that he passes of the "country suffer", expresses a certain idealization of a lifestyle that corresponds to a traditional dominance, that he want´s to be reproduced. Although it looked for the solution for the drought through the modernization of the economy by the adoption of advanced methods as the irrigation, his concern went back to the conservation of the economical and cultural political hegemony of that elite. Thus, his inquietude with the process of integration of the subordinate sections, justifies his consensual speech, harmonic as organic intellectual of the agrarian-commercial bourgeoisie of the Brazilian Northeast

Nas asas de Ícaro: uma análise da Pedagogia Freinet do 2º ao 5º ano do Ensino Fundamental na perspectiva da ação docente continuada

Célestin Freinet was one of the most memorable educators of the twentieth century. He presented some educational alternatives that had the objective of stimulating the construction of pedagogic actions to promote the social development of the student based upon a work centered on the free expression as the way to self-structure the knowledge. With a permanent proposal of research based on the enquiry-based learning, Freinet set human capacity (cognitive, social-affective, psychometrical) taking cooperation in consideration on the processes of knowledge construction. Based on this referential, this present work has the objective to show Freinet s pedagogy in a continuous teaching action from 2nd to 5th grade focusing the teacher s discourse and also the educative practice of the students of a city public school in Natal. The observed work revealed the teacher s discourse and educative experience and delineated the students development while immersed into Freinet s educational practice. By virtue of the nature and specificity of the theme that guided our research, we chose a qualitative approach to it, as a way of conducting ourselves during our investigative process. We observed and analyzed the method that was used to conduct the activities in the classroom, as well as the ways of expression that the children used through drawings, words (oral text), or through writing. We highlight, among the written texts, the individual and collective texts, and also letters and notes, which during some moments served as a base to express a diversity of languages. The results, after a analyzing the research data, point towards a teaching practice that favors the construction of a significant learning process through the grasping of the school environment, on which all these factors are based: society, knowledge acquisition, abilities, attitudes and values. This learning process also strengthens human solidarity bonds and mutual tolerance, on which the student s social life is seated.

Efeitos agudos da aplicação do laser de baixa potência sobre o desempenho neuromuscular do sóleo em sujeitos saudáveis

A laserterapia de baixa potência (LBP) tem demonstrado recentemente ser capaz de aumentar a resistência à fadiga, bem como potencializar o desempenho neuromuscular através de seus efeitos metabólicos e fotoquímicos. Estudos anteriores mostraram que o LBP reduziu o estresse oxidativo do exercício, promovendo um retardo da fadiga muscular e minimizando seus efeitos deletérios. O objetivo desse estudo foi avaliar se a aplicação do LBP antes de um protocolo de fadiga teria efeito sobre o desempenho neuromuscular nas variáveis eletromiográficas e dinamométricas do músculo sóleo em sujeitos saudáveis. Esta pesquisa caracterizou-se como um estudo experimental do tipo ensaio clínico controlado, randomizado e cego, no qual participaram 60 voluntários de ambos os sexos, com faixa etária entre 18 e 28 anos e fisicamente ativos, segundo o questionário internacional para a prática de atividade física (IPAQ). Os sujeitos foram alocados randomicamente em três grupos: Controle (G1), Placebo (G2) e Laser (G3) e todos os voluntários foram submetidos a uma avaliação inicial (AV-1), um Protocolo de Fadiga e uma avaliação final (AV-2), compostas por contrações isocinéticas para flexão plantar a uma velocidade de 90°/s. Os resultados encontrados nesse estudo mostraram que não houve diferença estatística entre os três grupos da pesquisa nas variáveis eletromiográficas de RMS e Frequência Mediana, contudo, em relação à dinamometria, o grupo que recebeu a aplicação do Laser obteve um índice de fadiga significativamente menor (p=0,04) quando comparado aos grupos Controle e Placebo. Além disso, a aplicação do laser pré-exercício também resultou em um aumento nas variáveis de desempenho potência e trabalho. Com isso, pode-se concluir que o LBP foi capaz de melhorar o desempenho do sóleo em sujeitos saudáveis, justificado pelo aumento da resistência à fadiga

Reinternações psiquiátricas no Rio Grande do Norte: implicações e impacto das novas estratégias de atenção à saúde mental

The Brazilian Psychiatric Reform based on the desinstitucionalization of the assistance, translated to the emphasis on community/territorial treatment and in the social inclusion of the mental suffering, promoted advances in the psychiatric restructuring. In the Rio Grande do Norte (RN), we can enumerate as advances of the Brazilian Psychiatric Reform the expansion of the mental health care chain and the implementation of some strategies that, together, aims to further the psychosocial attention of the individual with psych suffering and to reduce the indices of psychiatrics readmissions in the state. In the current Brazilian‟s mental health situation we were interesting in answered the following question: what the impact of the substitutes services‟ extension in the revolving door phenomenon? This search aims to analyze the revolving door phenomenon occurrences based on the news strategies of mental health care in the Rio Grande do Norte. This is a descriptive-exploratory study with a qualitative approach, oriented by the theoretical framework of critical-dialectical approach about the Brazilian Psychiatric Reform and using the thematic oral history as method of information collects. The search was realized on the Hospital João Machado (HJM), estate reference in psychiatric treatment, and the participants was 20 professionals that work on it. The collection of information had started after the approval of the UFRN Research Ethics Committee with the opinion number 216/2011 and CAAE number 0021.0.051.000-11 and was realized using the direct observation and semi-structured interview. The study‟s results were categorized in two categories and five subcategories of analysis. CATEGORY 1) Current situation of the mental health care chain in the RN, with the subcategories: 1.1 Impact of the new services of mental health care in the revolving door phenomenon in the RN; 1.2 Implications of the new services of mental health care in assisting user to the HJM; 1.3 Issues the permeate the mental health care chain in the RN. CATEORY 2) Main causes of the revolving door phenomenon in HJM, with the categories: 2.1 Family problems; 2.2 Lack of assistance after discharge from psychiatric hospital. In summary, we conclude that the extension of the mental health care chain contributed for the reduction of the psychiatrics re-hospitalization‟s indices in RN. However, we realized that territorial services of mental health care are not the only responsible for the revolving door phenomenon. Factors as family problems and the disarticulation of the assistance after the discharge from hospital influence on the perpetuation of hospitalizations and re-hospitalizations in the local scenario. To study the revolving door phenomenon that occur in the psychiatrics‟ assistance considering the news strategies of mental health care allowed us to approach the advances and challenges brought by the RPb and by the desinstitucionatization in the state, indicating the need for further discussions and problem-solving strategies of psychosocial care.

Determinação de dados de equilíbrio de fases para sistemas aquosos com eletrólitos

In the present work are established initially the fundamental relationships of thermodynamics that govern the equilibrium between phases, the models used for the description of the behavior non ideal of the liquid and vapor phases in conditions of low pressures. This work seeks the determination of vapor-liquid equilibrium (VLE) data for a series of multicomponents mixtures of saturated aliphatic hydrocarbons, prepared synthetically starting from substances with analytical degree and the development of a new dynamic cell with circulation of the vapor phase. The apparatus and experimental procedures developed are described and applied for the determination of VLE data. VLE isobarics data were obtained through a Fischer s ebulliometer of circulation of both phases, for the systems pentane + dodecane, heptane + dodecane and decane + dodecane. Using the two new dynamic cells especially projected, of easy operation and low cost, with circulation of the vapor phase, data for the systems heptane + decane + dodecane, acetone + water, tween 20 + dodecane, phenol + water and distillation curves of a gasoline without addictive were measured. Compositions of the equilibrium phases were found by densimetry, chromatography, and total organic carbon analyzer. Calibration curves of density versus composition were prepared from synthetic mixtures and the behavior excess volumes were evaluated. The VLE data obtained experimentally for the hydrocarbon and aqueous systems were submitted to the test of thermodynamic consistency, as well as the obtained from the literature data for another binary systems, mainly in the bank DDB (Dortmund Data Bank), where the Gibbs-Duhem equation is used obtaining a satisfactory data base. The results of the thermodynamic consistency tests for the binary and ternary systems were evaluated in terms of deviations for applications such as model development. Later, those groups of data (tested and approved) were used in the KijPoly program for the determination of the binary kij parameters of the cubic equations of state original Peng-Robinson and with the expanded alpha function. These obtained parameters can be applied for simulation of the reservoirs petroleum conditions and of the several distillation processes found in the petrochemistry industry, through simulators. The two designed dynamic cells used equipments of national technology for the determination of VLE data were well succeed, demonstrating efficiency and low cost. Multicomponents systems, mixtures of components of different molecular weights and also diluted solutions may be studied in these developed VLE cells

Avaliação de bactérias nitrificantes em filtros biológicos submersos aerados

This study investigates a new treatment system of wastewater by anaerobic and aerobic biological filters for nitrogen modification. The main objective of this study was evaluate, on a pilot scale, quantitatively and qualitatively the bacterian nitrifying community in a experimental sewage treatment system made by aerobics biological filters in series, in search of figure out the dynamic of nitrogen modification process. It was collected and laboratorial analysed microbiologically, regarding NMP of Nitrosomonas e Nitrobacter, and physical-chemically considering nitrogen sequence. We conclude that: the association in aerobic biological filters under nutrition controlled conditions and oxygen level allows the appearance of bacterian community responsible for the nitrogen modification; the method used, despite its limitations, provided the selection of autotrophic nitrifying microorganisms, allowing the identification of Nitrosomonas and Nitrobacter; the flow direction tested in the experimental unit did not affect the nitrifying bacterial community, certainly because they were kept drowned and did not occur flow speed that could breake the formed biomass; the nitrification process happened in aerated biological filters in all phases of the research, comproved by microbiological tests; in the third phase of the research the increase of the oxygen rate was significant for the nitrificant bacterian community in the aerate biological filters, allowing its growth, occurring relation between the efficiency of nitrification system and the quantity of organisms responsible for this process; the conduit used in aerated biological filters showed satisfactory performance support material to the nitrifying bacteria development

Centros de especialidades odontológicas: avaliação da atenção de média complexidade na rede pública da Grande Natal

The Specialized Dental Care Centers (CEO) were developed to provide specialized dental care to the population, given the accumulated needs of health since the past. They must operate as units of reference for the Oral Health Team of the Primary Care, complementing the dental procedures performed at this level of attention. This study aims to assess the performance of CEOs of the Grande Natal Health Region as a strategy of Secondary Care consolidation in oral health through users, dentists and managers. For this to try to identify factors about access, hosting and satisfaction with the service, the actions developed in these centers, integration between the CEOs and the Basic Health Units (UBS), considering the reference and counter reference. Data were collected through semi-structured interview, conducted in four CEOs, among 253 users, 31 dentists and 4 managers. It was submitted to descriptive statistical analysis and to content analysis by software ALCESTE 4.5. The results revealed that the specialties of prosthesis, endodontics and surgery were the most sought by 38.2%, 23.7% and 21.7% of respondents, respectively. It was noticed that among users aged 18 to 30 years-old the greatest demand is for the specialty of endodontics (44.4%) and over 50 years for prosthesis (76.4%). There is a weakness in the reference and counter reference between UBS and CEO, because part of users goes directly to the centers without going before to the Primary Care and the majority does not want to return to the dentist of Health Unit. Satisfaction with care was reported by 90.9% of users, because they resolved the problems needed and were welcomed by the team. But the delay in care was the main factor for not satisfaction. For most dentists, some users could solve their problems completely in Primary Care, which shows the existence of unnecessary referrals to the CEOs, however they consider the existence of limiting factors in UBS that compromise the service. Most dentists revealed that some users do not get to CEOs with the basic dental treatment done, and some of them do not counter reference users. It can be concluded that the studied CEOs are being resolutive for those who access them, offering necessary care for the population, and if they don t account with this service, will encounter obstacles to resolution of problems, ranging seek care service in particular, in another public sector, or even giving up treatment. However, it is perceived the need of professionals training to understand the importance of the reference and counter reference, to that they can better serve and guide users. It is also important that cities offer better conditions to UBS and CEOs, so they can work together, with complementary actions of oral health, seeking full care, aiming for better resolution to the users' health problems
