Do olhar inquieto ao olhar comprometido: uma experiência de intervenção voltada para a atuação com alunos que apresentam paralisia cerebral

Compte tenu de l importance de la formation des enseignants pour répondre, de nos jours, aux besoins des élèves dont les caractéristiques marquantes sont la diversité et la différentiation, desquels nécessairement font partie , à un échelon croissant, des personnes atteintes d une déficience quelconque ; devant le constat que les actuelles politiques d éducation, en fonction de leurs limitations, peuvent être considérées comme un des principaux facteurs qui entravent la concrétisation d un vrai processus d inclusion de ces personnes ; compte tenu, encore, que le confront des situations éducatives concernant le processus d inclusion de ceux ayant des déficiences physiques, notamment lorsqu il s agit d élèves atteints de paralysie cérébrale, engendre chez les enseignants un état de troublante inquiétude du fait de ne se sentir convenablement préparés pour se confronter avec des situations pareilles, cette recherche, centrée sur cette problématique, a chosi comme objectif planifier, mettre en marche et analyser un programme d intervention pédagogique dans une école régulière de la ville de Natal/RN, auprès de quatre enseignants de l école fondamentale (7e Série) qui avaient reçu, dans leur classe, deux élèves atteints de paralysie cérébrale. S utilisant comme recours méthodologique de la recherche-action, le programme d intervention s est structuré autour de troix axes thématiques : l attitudinal, le pédagogique et le vécu en milieu scolaire, sous la forme de discussions théoriques et la mise en oeuvre de ces thématiques. Les données qui devraient être soumises à l analyse ont été collectées à partir des procédés d observation, d entretiens avant et après l intervention, du régistre de photos et d un questionnaire. Les interprétations faites, basées dans la comparaison du discours des sujets ont signalé que les enseignants ont progressé dans la maîtrise des savoirs scienfiques concernant la paralysie cérébrale et dans la connaissance des personnes atteintes par cette déficience. Par rapport aux valeurs et significations attribuées par les enseignants à ce programme d intervention à partir de leur choix des photos dans l ensemble du déroulement de ce processus formatif, elles s expriment par une prise de conscience très marquée, de la part des enseignants, par rapport :aux besoins éducatifs des élèves atteints de paralysie cérébrale ; à l importance et au vrai rôle que l école doit jouer face aux politiques d éducation inclusive ; aux difficultés vécues par ces personnes, qui réclament le plus profond respect de leurs ingularités ; la reconstruction d une nouvelle image concernant ces personnes ; la constatation qu il est possible aux enseignants d adapter et même de créer à l école des ressources et matériaux pédagogiques envisageant la qualité du processus d enseignement et apprentissage de l élève atteint de paralysie cérébrale ; finalement, la perception de l importance du travail en équipe, d un milieu scolaire accessible à ces personnes et de l appuis de la famille dans le contexte de l éducation inclusive. Les résultats obtenus, issus de ce programme d intervention, d après l évaluation finale des sujets, de part de témoigner de son efficacité, montrent que l intervention a été une excellente opportunité d habiliter ces enseignants et d améliorer le processus d enseignement à l école choisie comme le locus de cette recherche

Estratégias de intervenção utilizadas por enfermeiros da ESF do município de Natal/RN no controle do câncer do colo de útero

Cancer of the cervix (cervical cancer) is the second most prevalent cancer among Brazilian women. The high rates of cervical cancer in Brazil justify the implementation of effective strategies to control this, which include actions to promote health, primary prevention, early detection, screening, treatment and palliative care. Despite the existence of the National Programme for Control of the CCU there was no reduction in the incidence and mortality of this disease in Brazil. The Family Health Strategy (FHS) has the potential to facilitate such control and, in this context, one should consider that nurses play a central role. The study aimed to know the general intervention strategies used by nurses FHS of Natal / RN in CCU control, and how specific: analyzing the knowledge of these nurses on the CCU, the actions developed in the ESF for the control of CCU and identify the difficulties faced by them to perform it. This is a descriptive exploratory quantitative developed through a structured interview guide with 106 nurses who have experience in controlling the CCU in FHS teams of Natal / RN. Data analysis was performed using descriptive statistic s. The results pointed to actions taken in the FHS to control the CCU, collection of cervical cancer screening, health education activities, nursing consultation, referral of suspected cases for medical monitoring and active women with abnormal test result . The actions that were not mentioned by the nurses included: forming groups of prevention and health promotion; expand coverage of exams and office hours of consultations, establishment of alternatives to end the pent-up demand in the health units, participation in treatment or rehabilitation process users with the CCU; interventions for pain management, alliances and partnerships with schools, in dustry and the use of protocols. This study can be seen that the practice nurses partially shares to the CCU in Natal / RN. The participants of this study, when asked about the CCU, specifically for signs and symptoms of disease and risk factors in general showed important gaps. Difficulties such as lack of materials for collection of Pap smear; inadequate physical space in the Health Units; pent-up demand in the service, delay in arrival of the test results; obstacles in the actions of referral and counter-referral and cultural factors make the CCU control is compromised. It is believed in this research contributed to a reflection on the importance of the role of nurses in the development of the ESF control actions CCU, pointing out the factors that affect these. It is important to involve all nurses who comprise the ESF as knowledgeable of the risk factors, signs and symptoms, and existing tools for the early detection of cervical cancer in the pursuit of quality improvement actions to promote women`s health, contributing in planning future interventions that may reduce mortality from this disease in Natal / RN.

Simulação de reservatórios não convencionais para armazenamento de gás natural veicular

The investigation of viability to use containers for Natural Gas Vehicle (NGV) storage, with different geometries of commercial standards, come from necessity to join the ambient, financial and technological benefits offered by the gas combustion, to the convenience of not modify the original proposal of the automobile. The use of these current cylindrical models for storage in the converted vehicles is justified by the excellent behavior that this geometry presents about the imposed tensions for the high pressure that the related reservoirs are submitted. However, recent research directed toward application of adsorbent materials in the natural gas reservoirs had proven a substantial redusction of pressure and, consequently, a relief of the tensions in the reservoirs. However, this study considers alternative geometries for NGV reservoirs, searching the minimization of dimensions and weight, remaining capacity to resist the tensions imposed by the new pressure situation. The proposed reservoirs parameters are calculated through a mathematical study of the internal pressure according to Brazilian standards (NBR) for pressure vessels. Finally simulations of the new geometries behavior are carried through using a commercially avaible Finite Element Method (FEM) software package ALGOR® to verify of the reservoirs efficincy under the gas pressure load

Avaliação da remoção de sulfeto de hidrogênio do gás natural em uma coluna de absorção

Natural gas, although basically composed by light hydrocarbons, also presents in its composition gaseous contaminants such as CO2 (carbon dioxide) and H2S (hydrogen sulfide). Hydrogen sulfide, which commonly occurs in oil and gas exploration and production activities, besides being among the gases that are responsible by the acid rain and greenhouse effect, can also cause serious harm to health, leading even to death, and damages to oil and natural gas pipelines. Therefore, the removal of hydrogen sulfide will significantly reduce operational costs and will result in oil with best quality to be sent to refinery, thereby resulting in economical, environmental, and social benefits. These factors highlight the need for the development and improvement of hydrogen sulfide sequestrating agents to be used in the oil industry. Nowadays there are several procedures for hydrogen sulfide removal from natural gas used by the petroleum industry. However, they produce derivatives of amines that are harmful to the distillation towers, form insoluble precipitates that cause pipe clogging and produce wastes of high environmental impact. Therefore, the obtaining of a stable system, in inorganic or organic reaction media, that is able to remove hydrogen sulfide without forming by-products that affect the quality and costs of natural gas processing, transport and distribution is of great importance. In this context, the evaluation of the kinetics of H2S removal is a valuable procedure for the treatment of natural gas and disposal of the byproducts generated by the process. This evaluation was made in an absorption column packed with Raschig ring, where natural gas with H2S passes through a stagnant solution, being the contaminant absorbed by it. The content of H2S in natural gas in column output was monitored by an H2S analyzer. The comparison between the obtained curves and the study of the involved reactions have not only allowed to determine the efficiency and mass transfer controlling step of the involved processes but also make possible to effect a more detailed kinetic study and evaluate the commercial potential of each reagent

Balanço energético de um forno túnel de cerâmica estrutural convertido de lenha para gás natural

In energy systems, the balance of entrances, exits and losses are fundamental to rationalize the energy consumption, independently of the source (sun, natural gas, wind, water, firewood or oil). This estimate is important so much in the phase of project of the facilities, as in the exploration or operation. In the project phase it indicates the energy needs of the process and the contribution of the energy in the cost of the product and the capacity of storage of the fuel and in the operation phase it allows to evaluate the use of the energy in the process of it burns, showing the weak points that should suffer intervention to improve the efficiency. With this tool, it can be implemented routines of calculation of thermal balances in ovens of it burns of structural ceramic, in way to generate an optimized mathematical model for application in the current and promising structural ceramic brazilian industry. The ceramic oven in study is located in the metropolitan area of Natal (Rio Grande do Norte) and it is a continuous oven of the type wagons tunnel, converted of firewood for natural gas and it produces blocks of red ceramic. The energy balance was applied in the oven tunnel before and after the conversion and made the comparisons of the energy efficiencies (it burns to the firewood and it burns to natural gas), what showed that the gaseous fuel is more efficient when we burn structural ceramic in ovens tunnels. When we burn natural gas, the requested energy is smaller and better used. Tests were accomplished in the burned product that showed the best quality of the burned brick with natural gas. That quality improvement makes possible to accomplish new interventions for the most rational use of the energy in the oven tunnel of the Ceramic in study and in the industries of structural ceramic of the whole Brazil, that need control tools of burning and of quality

Estudo de uma coluna de absorção recheada para desidratação do gás natural utilizando microemulsão como absorvente

During natural gas processing, water removal is considered as a fundamental step in that combination of hydrocarbons and water favors the formation of hydrates. The gas produced in the Potiguar Basin (Brazil) presents high water content (approximately 15000 ppm) and its dehydration is achieved via absorption and adsorption operations. This process is carried out at the Gas Treatment Unit (GTU) in Guamaré (GMR), in the State of Rio Grande do Norte. However, it is a costly process, which does not provide satisfactory results when water contents as low as 0.5 ppm are required as the exit of the GTU. In view of this, microemulsions research is regarded as an alternative to natural gas dehydration activities. Microemulsions can be used as desiccant fluids because of their unique proprieties, namely solubilization enhancement, reduction in interfacial tensions and large interfacial area between continuous and dispersed phases. These are actually important parameters to ensure the efficiency of an absorption column. In this work, the formulation of the desiccant fluid was determined via phases diagram construction, employing there nonionic surfactants (RDG 60, UNTL L60 and AMD 60) and a nonpolar fluid provided by Petrobras GMR (Brazil) typically comprising low-molecular weight liquid hydrocarbons ( a solvent commonly know as aguarrás ). From the array of phases diagrams built, four representative formulations have been selected for providing better results: 30% RDG 60-70% aguarrás; 15% RDG 60-15% AMD 60-70% aguarrás, 30% UNTL L60-70% aguarrás, 15% UNTL L60-15% AMD 60-70% aguarrás. Since commercial natural gas is already processed, and therefore dehydrated, it was necessary to moister some sample prior to all assays. It was then allowed to cool down to 13ºC and interacted with wet 8-12 mesh 4A molecular sieve, thus enabling the generation of gas samples with water content (approximately 15000 ppm). The determination of the equilibrium curves was performed based on the dynamic method, which stagnated liquid phase and gas phase at a flow rate of 200 mL min-1. The hydrodynamic study was done with the aim of established the pressure drop and dynamic liquid hold-up. This investigation allowed are to set the working flow rates at 840 mL min-1 for the gas phase and 600 mLmin-1 for the liquid phase. The mass transfer study indicated that the system formed by UNTL L60- turpentine-natural gas the highest value of NUT

Avaliação e modelagem da absorção de H2S do gás natural em coluna de leito estagnado

Natural gas, although basically composed by light hydrocarbons, also presents contaminant gases in its composition, such as CO2 (carbon dioxide) and H2S (hydrogen sulfide). The H2S, which commonly occurs in oil and gas exploration and production activities, causes damages in oil and natural gas pipelines. Consequently, the removal of hydrogen sulfide gas will result in an important reduction in operating costs. Also, it is essential to consider the better quality of the oil to be processed in the refinery, thus resulting in benefits in economic, environmental and social areas. All this facts demonstrate the need for the development and improvement in hydrogen sulfide scavengers. Currently, the oil industry uses several processes for hydrogen sulfide removal from natural gas. However, these processes produce amine derivatives which can cause damage in distillation towers, can cause clogging of pipelines by formation of insoluble precipitates, and also produce residues with great environmental impact. Therefore, it is of great importance the obtaining of a stable system, in inorganic or organic reaction media, able to remove hydrogen sulfide without formation of by-products that can affect the quality and cost of natural gas processing, transport, and distribution steps. Seeking the study, evaluation and modeling of mass transfer and kinetics of hydrogen removal, in this study it was used an absorption column packed with Raschig rings, where the natural gas, with H2S as contaminant, passed through an aqueous solution of inorganic compounds as stagnant liquid, being this contaminant gas absorbed by the liquid phase. This absorption column was coupled with a H2S detection system, with interface with a computer. The data and the model equations were solved by the least squares method, modified by Levemberg-Marquardt. In this study, in addition to the water, it were used the following solutions: sodium hydroxide, potassium permanganate, ferric chloride, copper sulfate, zinc chloride, potassium chromate, and manganese sulfate, all at low concentrations (»10 ppm). These solutions were used looking for the evaluation of the interference between absorption physical and chemical parameters, or even to get a better mass transfer coefficient, as in mixing reactors and absorption columns operating in counterflow. In this context, the evaluation of H2S removal arises as a valuable procedure for the treatment of natural gas and destination of process by-products. The study of the obtained absorption curves makes possible to determine the mass transfer predominant stage in the involved processes, the mass transfer volumetric coefficients, and the equilibrium concentrations. It was also performed a kinetic study. The obtained results showed that the H2S removal kinetics is greater for NaOH. Considering that the study was performed at low concentrations of chemical reagents, it was possible to check the effect of secondary reactions in the other chemicals, especially in the case of KMnO4, which shows that your by-product, MnO2, acts in H2S absorption process. In addition, CuSO4 and FeCl3 also demonstrated to have good efficiency in H2S removal

Educação científica no contexto pós-ontológico: por uma concepção plural de conhecimento e educação

The development of this work arises from the research of sociological and philosophical characters contemplating also other approaches which aims to answer the followingquestions: what is the responsibility of science teaching for the image one has about science? ; which scientific education should be designed for nowadays? . After considering the assumptions brought along by rationalism and the criticisms to the illuminist model proposed by sociology and philosophy of science, as well by the biology of the knowing process, going through discussions concerning post-modernity issues, one is given to understand that the image of science has become the central point of discussion in the last hundred years, including what concerns the area of science teaching, and that practically none of those discussions really reached natural science classes indeed. We adopt the term postontological to characterize the recent proposals on philosophy and sociology, because we evaluate that this term allows a better identification of the scientific realism crisis, which supports the existence of an ontological domain which science, and only science, is able to understand. One notices that the general public is not aware of those discussions, mainly if they are science teachers and students. So we believe that discussing the logic in which science is structured, the new understandings concerning the scientific undertaking, especially those of an externalist character, and the relationship between science and society, all of this contributes to build up a science teaching which contemplates a reflective contribution, besides allowing the inclusion of the study of other epistemologies in the educational practice. We argue that a revisionist posture seems to be the most appropriate for the contemporary scientific education, contemplating, besides the teaching of the usual science contents, discussions on the issues involving that knowledge, as well as respecting epistemologies alternative to the modern Western scientific one, in order one can work on the perception of local knowledge generated from other epistemological bases. We describe here practical activities we did involving teachers (short-term courses) and high-school students in an inland school in the Rio Grande do Norte state, in Brazil, as a way to demonstrate the possibility of interventions which can take those conceptions, discussions and changes to the classroom

A formação pós-graduada em ensino de ciências naturais e matemática de docentes do IFRN: implicações na atuação docente

This research part of the educational context of the Federal Rio Grande do Norte, through the resumption of legal frameworks that characterize it as an institution belonging to the Federal Network of Professional Education and Technology Brazilian, with a focus on continued education policies for the servers who work there specifically teachers, especially those who have their work in the Teaching of Natural Science and Mathematics. To do this the cut in an agreement between the IFRN and UFRN PPGECNM through the professional master's degree Teaching of Natural Sciences and Mathematics. This agreement as we have research collaborators 08 master teachers who graduated in the period 2004 to 2010, so we undertook a qualitative and quantitative research aimed to conduct the study in general terms of description and analysis of the impacts caused by the formation of masters IFRN in PPGECNM UFRN, taking into account the production of the same academic (dissertation), his performance in the context of the institution and the historical, social, economic and political aspects involved, and also meet the guidelines of the project at the Observatory in 2008 - MEC / CAPES / BSD-P. We used the theoretical options methodological elements of Comprehensive Interview and multireferentiality, our data collection instrument was the main interview, we also performed the analysis of dissertations by lecturers and teachers featured, from the specific descriptors used in catalogs USP / IFUSP (1992, 1996) and UNICAMP / FE / CEDOC (1998) and by other researchers. In analyzing and understanding the speech of the interviewees were able to identify the implications of teacher education in the school context, the motivation to seek the Master; how was the construction of the object of study of the educational product and its use in teaching practice and intervention, the question of the role of master teachers in the school environment to the post master taking into account changes in professional performance and influence in the working groups, how does the use of research and investigation in the classroom after training and between training and educational quality in the context of IFRN. In reading and analysis of the dissertations were able to identify the main focus and under-explored thematic focus as well as the theoretical methodological references. At the end of the research developed a product that could be used for technical analysis studies and assessment in quantitative terms the results achieved by the master teachers IFRN through his training in PPGECNM UFRN

A etnomatemática dos trabalhadores das cerâmicas de Russas-Ce e o contexto escolar: delineando recomendações pedagógicas a partir de uma experiência educacional

It is still common among contemporary educational proposals an overemphasis abstraction, to the formalism and symbolism of mathematical knowledge at the expense of the sociocultural aspects of Mathematics. Coming up by questioning some academic mathematical tenets and valuing knowledge developed in different sociocultural contexts within Mathematical Education, the Ethnomatematics is consolidating itself as a research field. Despite its contributions to the educational context, because its philosophical character and the paucity of debates about the subject, the implementation of educational proposals for basic education are scarce. Given this situation, this dissertation comes up with a view to develop an educational intervention in the light of Ethnomathematics in a class of 6th grade of an elementary school from a red ceramic industries workers community, located in a countryside from Russas-CE and from this intervention, to develop a set of pedagogical recommendations aiming basic education teachers. Adopting a perspective of qualitative research, particularly guided by action research, this study used observation, field diary, interviews and activities with students as tools for data collection. It was found that the use of field research as part of teaching and learning favored the placement of students as critical subjects of their own reality . Furthermore, the educational experience culminated in the development of a method of teaching based on a relationship between protocooperational Ethnomatematics and the Resolution of Problems. It is necessary to broaden the debate about the ways in which the Ethnomatematics can contribute to the school context, bringing proposals closer to the reality of basic education teachers in order to help the promotion of an education which values cultural diversity without taking away the students from the access of the academic knowledge

Um enfoque psicológico da educação ambiental no contexto da gestão: uma experiência de Fernando de Noronha

Currently, many companies pay attention to the necessities of change of attitude in relation to the use of the natural resources and the environment quality of its products, mainly to keep a positive and competitive image in the market. This new concept of management associates the productive activities to the care with environment using the education of environment as a tool of programs of qualification directed toward the promotion of pro-environment behaviors. For effectiveness of this management it is essential the attachment of the employees and the major understanding of the importance of the preservation of the environment. This was the objective of the qualification process carried out in a lodge in Fernando de Noronha island. The purpose of this study, therefore, was to verify the power of this management system which fulfills the objectives of the environmental education. It was applied questionnaires to employees of three Inns and carried out a interview, in one Inn, with the participants of the program of qualification. The analysis of the data showed that the actions as care with the environment are strongly associates to the management system, which includes garbage control, as well water economy. It was observed that the environment accomplishment (EcoAntro) of the employees with environment decreases in proportion to their qualification. In the same way, as higher the instruction level, of the speaker and/or of the father, less is the apathy for environmental questions. It was also noticed that the knowledge about the development sustainability was very poorly used by the interviewed. The pro-environment behavior mentioned before, is not necessarily related to a local autonomy posture that could express a behavior related to job but not to environment it self. Therefore, a complete understanding about the reverberation of environment information an all the placed factors in a life stile facing a construction of sustainability remains as a question to be studied in future researches

Interfaces cultural, política e organizacional do projeto caminhos do frio rota cultural no contexto da regionalização do turismo no brejo paraibano

This study is the analysis of cultural, political and organizational interfaces of "Caminhos do Frio Rota Cultural" Project in the context of tourism regionalization in Brejo Paraibano and it presents the characterization, routing and inventory of six municipalities of the Project, as well as the identification of cultural elements used for tourist in the routing of the pond, the investigation of political and organizational articulation and the verification of participation of each producing agent in the development of tourism resulting from the swamp of Paraiba. This is a qualitative descriptive and exploratory study, which makes use of the interpretive paradigm to perform an analysis of the environment where occurs the regionalization of tourism in Brejo of Paraíba and the social actors involved in this process in order to pursue development of the region through culture and tourism, with the collection spot in the six counties of the Project participants collected through interviews with managers, community, government agencies and tourist trade, and the use of the technique of direct observation. This time, with the data analysis it was possible to establish the production situation and its cultural and tourist development in the region of Brejo (PB), where culture has become a developmental tool within the tourism industry due to its innovation potential. It was possible to ratify the undisputed vocation of cultural tourism in the region in question, since other projects being developed with the use of cultural resources with a strong influence on the policies of regional tourism. Thus, the main result was that was seen is that the regional development has triggered a refunctionalisation / reappropriation of space just rebuilding a new territorial organization through the development of a regional autonomy of management, a capacity of collective ownership and the use of economic surplus, a spontaneous process of social inclusion as well as awareness and mobilization tourist (even if initial and shy), an appreciation of natural and cultural assets for all stakeholders and especially identification of the population with its region and its culture, as to achieve regional development is not enough to increase the economic, but above all the promotion of endogenous social factors such as changes in social and cultural values and the integration of social actors in this process. Finally, taking into account the definitions of sustainability, it is considered that cannot be said that the development model seen in the swamp of Paraiba is sustainable, but it is a model of regional development based on the unique characteristics that each municipality has and create a regional identity and have correponded expectations / desired results and therefore the viability of the region through the development of cultural tourism was proven

Turismo, capital social e produção do espaço: uma leitura a partir do município de Natal/RN no período de 1980 a 2012

Nowadays, there is a tourism phase in the city of Natal/RN called internationalization of tourism , which shows a tourism model with a planning and an administration, based on the needs of the visitors. Such process shows that the production as well as the reproduction of the city spaces with the goal of favor tourism excludes of its composition the effective participation of local subjects. Thus, the research is a result of the perception of tourism as an activity with a meaningful power of transformation of the social and natural space taking into account the low participation of the residents in the decisions of the tourism activities in the city of Natal/RN. Despite that reality, it is possible to note Natal that civil society, starts to mobilize its citizens trying to develop collective actions to low the negative impacts caused by the bad planning as wells not efficient tourism administration, trying to put in action the right of the local population to take part in the decisions of the city activities. Having this panorama as background, this paper aims at investigating in which way the mobilizing action of the social capital in Natal has contributed to change the spatial production which is part of the process of expansion of tourism in Natal/RN? The research presents a temporal picture which starts in the year of 1980, when occurs the first effective state intervention aiming to develop tourism in the capital, taking into account an analysis of 2012. Concerning the spatial picture, the research investigates the beaches of Natal which concentrates criteria and actions such as: visitation, tourism appeal and focus of investments, highlighting the following beaches: Ponta Negra, Areia Preta, Praia dos Artistas, Praia do Meio, Praia do Forte and Redinha. This study is of a descriptive and exploratory nature concerning its goals. With respect to the treatment of its object it is a qualitative research. The data was collected through structural interviews, with open questions. Regarding the methodological choices, it was used the content analysis proposed as well as the collective discursive subject methodology. The results show that there´s not yet in Natal a meaningful social capital related to tourism, capable to change the spatial production related to the activity. It should be stressed that Natal social capital presents difficulties concerning the incentive to trust, spontaneous cooperation and the civic participation, which are the foundation for the development of an effective social capital, which makes it harder for a more expressive articulation in the reality in Natal/RN. It should be stressed, as an answer to the research questions, that tourism in Natal/RN is represented by social and spatial segregation. In other words it emphasizes mainly the action of hegemonic agents (State and market), leaving little room for the participation of society. It can be noticed that the actions related to tourism in Natal keeps the popular participation out of the way. Thus, it can be said that the social capital in Natal/RN does not yet contribute to a more fair spatial production related to the expansion of the tourism as well as the well being of the population of Natal/RN. In conclusion, it should be taken into account that this participation do exists but not in a meaningful way. In other words, it´s not enough yet to cause meaningful changes in the actions which tourism needs nowadays in Natal/RN

Colonização natural por espécies nativas e exóticas das encostas degradadas da Serra do Mar

Os deslizamentos são eventos inerentes à dinâmica da Serra do Mar, nos trechos mais declivosos. Contudo, devido a alguns fatores de intervenção, como a poluição atmosférica, ocupação da base dos morros e outros, a incidência desses eventos tem aumentado. Diante disso, este estudo objetivou avaliar a dinâmica de colonização de áreas de encosta degradadas, como forma de subsidiar ações de recuperação. Para tanto, foram adotadas duas áreas experimentais, localizadas em trechos da serra do Mar próximos à Baixada Santista, onde foram lançadas parcelas de 1 m² e obtidos dados fitossociológicos. em seguida, as áreas foram limpas e os mesmos parâmetros da avaliação inicial, registrados, mensalmente, ao longo de um ano. Foram encontradas 20 espécies, pertencentes a 14 famílias botânicas, em sua maioria espécies exóticas ou nativas não regionais.
