Transporte longitudinal de sedimento na zona costeira de Natal/RN

The longshore sediment transport (LST) is determinant for the occurrence of morphological changes in coastal environments. Understanding their movement mechanisms and transport is an essential source of information for the project design and coastal management plans. This study aims to characterize, initially, the active hydrodynamic circulation in the study area, comprised of four beach sectors from the south coast of Natal, assessing the average annual LST obtained through three proven equations (CERC, Kamphuis and Bayram et al.), defining the best formulation for the study area in question, and analyze the seasonal variability and the decadal transport evolution. The coastal area selected for this work constitutes one of the main tourist corridors in the city, but has suffered serious damage resulting from associated effects of hydrodynamic forcings and their disorderly occupation. As a tool was used the Coastal Modelling System of Brazil (SMC-Brazil), which presents integrated a series of numerical models and a database, properly calibrated and validated for use in developing projects along the Brazilian coastline. The LST rates were obtained for 15 beach profiles distributed throughout the study area. Their extensions take into account the depth of closure calculated by Harllermeier equation, and regarding the physical properties of the sediment, typical values of sandy beaches were adopted, except for the average diameter, which was calculated through an optimization algorithm based on equilibrium profile formulation proposed by Dean. Overall, the results showed an intensification of hydrodynamic forcings under extreme sea wave conditions, especially along the headlands exist in the region. Among the analyzed equations, Bayram et al. was the most suitable for this type of application, with a predominant transport in the south-north direction and the highest rates within the order of 700.000 m3 /year to 2.000.000 m3 /year. The seasonal analysis also indicated a longitudinal transport predominance in the south to north, with the highest rates associated with the fall and winter seasons. In these periods are observed erosive beach states, which indicate a direct relationship between the sediment dynamics and the occurrence of more energetic sea states. Regarding the decadal evolution of transportation, it was found a decrease in transport rate from the 50’s to the 70’s, followed by an increase until the 2000’s, coinciding with the beginning of urbanization process in some stretches of the studied coastline.

Vulnerabilidade socioambiental no bairro de Mãe Luíza, Natal – RN/Brasil

This work has as object the elaboration of social environmental indicator of disaster risk that are present in precarious areas of human occupation, related to intense environmental dynamic from the perspective of the studies about the subject in Geography. The District of Mãe Luiza in Natal, capital city of Rio Grande do Norte, was defined as the study area. The place was chosen because it presents –historically- several vulnerability conditions and exposure to disaster risk. After a local social environmental description, two indexes were elaborated: the Social Vulnerability Index (SVI or IVS in Portuguese), based on 17 (seventeen) variables arranged on a questionnaire addressed to the population nucleus of the district, on regular grid (systematic sampling), classified into 5 (five) levels of SV from the weighted average; and the Physical and Natural Exposure to the Mass Movements Index (EMMI or IEMM in Portuguese) which had 16 (sixteen) variables that feature conditions of exposure to the mass movements in the district with classified levels from the weighted average of 1 (one) to 5 (five). The relationship between these two results, specialized in the district map, produced the Social Environmental Vulnerability Index (SEVI or IVSA in Portuguese) of Mãe Luiza, also classified into 5 (five) levels, following the Boolean logic correlation for cartographic overlay with use of computer software ArcGIS v.9.3, being named as: Very Low; low; average; high; and Very High Environmental Vulnerability in District. The study is based on the methodology proposed by Guerra et al (2009) for EMMI and by Almeida (2010) for SVI. They were modified and adapted according to the local reality, producing a new methodology in this study area. It was concluded that the neighborhood has most of its area with High and Very High Socio-environmental vulnerability to disasters, defined seven (7) critical areas, with Very High IVSA, and hazards associated with mass movements or flooding. In the end, the main issues that were found, such as generating elements for proposing mitigation measures and/or the proposed interventions were enumerated, related to structural order of vulnerability factors: how low constructive pattern of households; poor urban drainage; Real Estate forsaken in landslide routes; infrastructure ready access roads and slope containment. And social: as a lack of education about environmental risk; income and education of residents; presence of persons with limited mobility and/or those with special needs. This reality highlights the need for urgent action applied to the resolution and/or reduction of these problems, which is focusing the end of this work.

Música em projetos socioassistenciais governamentais: práticas e concepções culturais no Serviço de Convivência e Fortalecimento de Vínculos em Natal/RN

This present research focus at the teaching of music in social programs, it discuss about the teaching concepts that permeates the educational-musical practice presents in Serviço de Convivência e Fortalecimento de Vínculos (SCFV), of Complexo Dom Bosco, in Natal-RN. The Objective is to reflect upon the music teaching concepts and the relations between musical knowledge and culture. For this, it was problematized the concepts of music teaching and learning in governmental social projects through theoretical and empirical research. After this step, it was studied the cultural aspects involving the routine in the institutions the influenced the music learning at Serviço de Convivência e Fortalecimento de Vínculos, furthermore, and how these aspects are present in the constitution of the paradigms that involve music teaching. For this, it was used a qualitative approach and a case study as type of research. As data capture tool it was used the ethnographic write, photography, interviews as a Facilitator of music with the students of the program, and video recordings of musical learning situations. Theoretical support it was used authors who study the complexity, culture and music teaching in social projects. Finally, the conclusion is that musical learning, in the SCFV context, is involved of cultural conceptions steeped to the Oratório Dom Bosco space and the same time the Brazilian Social Assistance Policy. Sometimes these concepts are contradictory: discipline, leadership and combat social exclusion refer to dialogical cultural hologram of the institutions involved in the music education process.

O teatro musical enquanto prática pedagógica no meio eclesiástico: ressignificando o fazer artístico na Igreja Batista da Esperança, Natal-RN

The churches in Brazil have shown themselves as a very important space in the musical training of many individuals. However, we perceive in many of them an excluding and merely performatic musical posture. Their argument is the fact that they want to give worship to the Divine Being and, for that, they must always offer their best. Besides that, the culture of the talent and the gift has provoked the selection of people in the ecclesiastical musical practices. The musical theatre, also practiced in this context, has been following the same principles. Understanding that musical practices must be accessible to all people, we have seen, through the studies of Amelia Santa Rosa, 2006 and 2012, the musical theatre, for its various possibilities, as an important tool for the music teaching in this context in an integrating, motivating, interdisciplinary and liberating way. For this reason, through an action research, this work has aimed to investigate the applicability of the musical theatre as a pedagogical practice in the context of the Igreja Batista da Esperanca (Hope Baptist Church), in Natal-RN, verifying the impact of this experience to the ones involved. In order to accomplish this, we carried out the construction of a musical with all of the ones who wanted to be a part of this research, having or not having previous musical experiences. The data collection was made through the field diary, semi-structured interviews with the cast of the musical and pictures and videos of rehearsals and presentations. The main issues highlighted were categorized and properly analyzed, which showed us how much the musical theatre can be used as a musical pedagogical tool also effective in the ecclesiastical context. Thus, another conception of artistic endeavor could be brought to churches, contributing to the inclusion of new participants in their musical practices, expanding the studies on the musical theatre and the presence of music in these spaces a bit more, causing other future studies.

Templo Central da Igreja Evangélica Assembleia de Deus do Natal/RN: um estudo sobre música e educação musical

This study aims to investigate the music and the existing music education in Central Temple of the Evangelical Assembly of God Church of Natal/RN. The research question asks how are the musical practices, teaching and learning music that happens in this place. I used the qualitative approach conducting a case study. The theoretical framework were Arroyo (1999, 2000a, 2000b, 2002), Kraemer (2000), Souza (1996), Souza (2000, 2008, 2009), Green (1997), Queiroz (2004a, 2004b, 2005, 2007, 2010, 2011, 2013), Geertz (1989), Nettl (1992) and Merrian (1964). I conducted semi-structured interviews and participant observation with the direction of the music department, teaching coordination, students, teachers, musicians and conductors of the church. The study revealed that the relationship between music and education is beyond just a musical training, there are many relationships established as faith, belief in God and devotion. It was found that the views of musicians and conductors think the music teaching in the church to play in worship and praise God. In the musical training of students, he was working not only musical content; It was understood that music is a mediator of meanings that go beyond experiences and musical practices. The worship of God and the worship featuring musical practices and their effects are direct music classes. The research contributes to reflection and understanding of music and music education happens in the evangelical church and a greater understanding in the relationship between music education and the cultural context where it happens.

Preceptoria em profissionais de saúde: viabilizando meios para uma formação pedagógica em hospitais públicos em Natal-RN

This study aimed to construct and carry out a distance course of pedagogical training for health professional performing preceptorship functions in public health institutions. The preceptorship in health is a pedagogical practice that occurs in workplace, led by assistance professionals with teaching position or not, where the vast majority of these acts intuitively, reproducing their own training, confusing transmitting information with education. These preceptors often do not dominate the pedagogical knowledge, necessary for the organization of training activities, such as the various teaching-learning processes and the different assessment types. Student supervision is essential in the training process of students in the health field, and on the occasion of supervised internships that the teaching-learning process is based on practical experience with participation in real life situations and professional work. It was realized an exploratory study, descriptive with qualitative approach, with the development of tutoring teaching course in health as final product. Applied semi structured research instrument from may to july 2014. It were evaluated 162 health professionals who perform the preceptorship, which made it possible define the preceptor's profile and identify the educational requirements related to the educational process, which justified the construction of the program content and the professionals’ perception analysis about preceptorship through identification of three categories: clinic knowledge valuation; valuation of professional orientation and valuation of professional future. The course was available on distance mode through Moodle platform with forty hours of work load from October to November 2014. With the aim of capacitate the health professionals to development of necessary abilities and skills to tutoring performance through thoughts about tutoring concepts, professional training within the curricular guidelines and SUS precepts, the role of health professionals as educators, application of active teaching methodologies, and evaluation methods. The applications were done online through the provided link; 300 vacancies offered, 243 professionals applied, chosen 134 that works on tutoring, where 49 represented professionals that works on the location of the study. The course lasted 45 days, and counted with tutors responsible to interact and evaluate the students. 28 professionals joined the course, 12 concluded. Opportunities were identified to stimulate the involvement, however the professionals’ satisfaction shows that, make an investment on tutors education, starting from the Permanent Education precepts, will provide a bigger appropriation of the knowledge to the education and therefore the awareness of their role as an educator on work ambit, proportioning essential tools to tutors act while enabler of integration between theory and practice and result better teaching-learning process.

A releitura de um documento: o processo de tombamento do centro histórico de Natal (RN)

During over seven decades of institutionalizing the national heritage protection legal instrument it can be noticed the many ways of the instrument application, according to the approaches that were assigned to the spaces with heritage values and the dynamic of the elaborated thoughts within this theme. For the application of the instrument effectively, there is a long process that is carried out. This process begins with the study elaboration that aims to subsidize and justify the motivation of property protection, as well as the proposal of buffer zones and national protection areas delimitations, completing the process with the denial of the request or with the publication of the definitive national protection area at the Official Gazette. Starting with the relation between the existing heritage values identification into the historical centres and the definition of its protection areas that the area management will be done, based as well into the management intervention norms established for the protection area perimeter. From this context, the present essay has as porpoise to discuss the approach used for the identification and selection of a historical centre liable for national protection and the repercussion of this identification into the national protection area the was established, using a case study of the national protection of the historical centre of the city of Natal. Starting from the assumption that there are inconsistences and distortions about the text speech of the written document and the spatial delimitation of this document, motivated by an area that privileges the edifications rather than the urban space. Beginning with the urban history methodology, we are based on the precepts of Rossi (2011), Lamas (2010) and Cullen (2009) for that space reading, along with what Sant’Anna (2004) defines as “city-document” to make a new reading of this “heritage value space” verifying if the proposed protection area reflects what is defined as motivation for the national protection area process during the recognizing process. Therefore, it is concluded that it is essential that the buffer zones and the national protection areas are aligned with the text presented at the national protection area instruction, so the norms and criteria definition management process are established. We highlight that a site management and the identified values protection become very difficult without a specific law that beacon the decisions that should be taken.

Uso e ocupação do solo e a transformação da paisagem na faixa litorânea da Via Costeira, município de Natal/RN

The coastal area of the city of Natal due to its location and natural potentialities has been an area where we have experienced big changes in its environment, at the expense of several forms of use and human occupation. On the coast of Via Costeira beach the process of use and land occupation was structured at the end of 1970s and early 1980s, as a result of the government policy which has developmental essence, based on the settlement of plenty big enterprises by the Parque das Dunas/Via Costeira Project. This project was created to install in Natal, capital of the state, infrastructure equipment on this stretch of coastline consisted of dune fields and many parts of ecosystems which have high natural relevance and fragility that used to present a semi-isolation in the urban city, for the development of tourist activities, which is considered as a viable economic solution capable of setting right serious socioeconomic problems that had persisted there. According to what was said so far, this study aimed to analyze the forms of use and land occupation besides the change of the landscape along the Via Costeira coast in the city of Natal/RN. These changes often take place without considering the complexity and fragility of natural ecosystems involved. The geoenvironmental study was based on the geosystemic theory, thus It was possible to analyze the human interventions in the superficial aspects of landscapes holistically. The practical procedures were contemplated with literature searches, followed by field work where were fulfilled the recognition and general characterization of the area in order to investigate and analyze the main types of land occupation and its use that have taken place there since big buildings began to come out, being supported by the legislation whose laws are about protection and conservation of coastal natural resources. The research also includes the identification and evaluation of the main types of negative impacts caused due to different forms of use that induce environmental and social conflicts nearby this shore. Thus, It was carried out a spatial and multitemporal analysis from orthophotos, aerial photographs and others taken during the field work besides satellite images too. The information which is taken out from these instruments was used to draw maps related to land occupation, spatial impacts and other thematic maps. We worked on a hypothesis that the implementation of mega enterprises on Via Costeira and many different forms of intensified use by human actions, has not considered the natural aspects and restrictions of use in this area, these ones would be the main factors that brought on the suppression and degradation in this environment and consequently the transformation of the natural landscape.

Estudo sobre a relação entre a atividade geomagnética e cintilações de sinais de GPS em Natal-RN (Brasil)

To identify the relationship between GPS scintillation in Natal-RN (Brazil) and geomagnetic disturbances of any intensities and variations, this work made analysis of the ionospheric behavior and magnetic indexes (Dst , AE and Bz of the interplanetary magnetic field) concerning to different periods of the solar cycle between 2000 and 2014. Part of the data of this research originated at the UFRN observatory, from a GEC Plessey board connected to an ANP -C 114 antenna, modified by Cornell University’s Space group Plasma Physics in order to operate the ScintMon, a GPS monitoring program. This study, therefore, found several cases of inhibited scintillations after the main phase of magnetic storms, a fact that, along with others, corroborated with categorization of Aarons (1991) and models of disturbed dynamo (according to Bonelli, 2008) and over-shielding penetration, defended by Kelley et al. (1979) and Abdu (2011) [4]. In addition to these findings, different morphologies were noted in such disruptions in the GPS signal in accordance with previous magnetic activities. It also found a moderate relationship (R2 = 0.52) between the Dst rate (concerning to specific time) and the average of S4 through a polynomial function. This finding therefore, corroborating Ilma et al. (2012) [17], is an important evidence that the scintillation GPS are not directly controlled by magnetic induction of storms. Completing this work, this relation did show itself as a way of partial predicting of scintillations.

Inclusão social de catadores de materiais recicláveis: estudo da política nacional de resíduos sólidos e da efetivação do trabalho decente em Natal/RN

The integrated management of municipal solid waste in Brazil is held legally responsible by the city council administration. This is done since the year 2010 with the publication of the National Solid Waste Policy term. According to the policy and law, each city must encourage the implementation of selective collection and the participation of waste picker´s entities aiming social inclusion. However, these actions haven’t yet reached its legal aims. These workers are considered regarding collection actions but are stripped of certain basic labor rights not in conformation with the Decent Work concept. This type of work, according to International Labour Organization, must be seen as work that is properly paid for and must be done regarding conditions of freedom, equity, security and able to provide workers with a dignified life conditions. Thus, this work aims to investigate the implementation process regarding the Solid Waste National Policy in Natal-Rio Grande do Norte in Brazil. This is done considering socio-productive insertion of recyclable material collectors. The research is substantiated by a qualitative approach as well as documental and bibliographical research. A field research considering the cooperatives as well “in locco" observation and semi-structured interviews were carried out between the time span of 2013 and 2014. In order to investigate decent daily working conditions the research emphasized municipal management actions in Natal towards social inclusion that aim to reflect on the progress and difficulties experimented. It is seen that even when these cooperatives receive government support there are still important struggles that need to be overcome. The worker´s tasks are risky, the work environment in not safe or is adequate in terms of health issues. There is the stigma of it being considered an occupational task, the low individual income distancing the activity regarding parameters of the Green Employment and Decent Work concept. On the other hand, the survey showed potential as the relentless pursuit on behalf of the cooperatives that still search better work condition improvement.

A gestão do programa saúde na escola no município de Natal/RN: um estudo de caso

The current conception of health deals with several influential factors, having education among them. Intersectoral organization is essential for Young and adult healthcare services. In this context the Healthcare in School Program was created which foresees a continuous articulation between health and education aiding the effectuation of the Healthcare Single System. The objective of this research is analyze the Healthcare in School Program (HSP) in Natal city in Rio Grande do Norte State taking into consideration the Intersectoriality of actions from the standpoint of the management. The chosen method was the case study, with qualitative approach. The sample was of the intentional kind including all components of the Natal city Intersectorial work group, composed by representatives of the Municipal Education Bureau, the State Education Bureau and Healthcare Municipal Bureau. The collecting data technique was the semi-structured interview. The data analysis was performed through the analysis of contents technique. For Data Show the following analysis categories were considered: Meaning of Intersectoriality; Actions Planning; Permanent and ongoing training for autonomy regarding to Healthcare Promotion; Difficulties and Potentials for actions operationalization. The outcomes allow us to indentify in Natal HSP intersectoral practices not developed yet. The manager professionals of Healthcare and Education do not get to acknowledge the power of Intersectoriality yet. The lack of commitment of some professionals stands out, planning is performed in a sectorial basis and without active participation of learners and community, there is duties accumulation and discouragement group, structural inadequacy and difficulty on the ongoing of the program actions. Despite the existing fragmentation, the program has contributed to the professional qualification and development of education actions regarding to healthcare along with learners. Therefore we conclude that healthcare, education and society have lots of challenges to face in order to consolidate Intersectoriality and the Healthcare in School Program and the and the implementation of the guidelines of the Healthcare Single System in Natal city in the state of Rio Grande do Norte.

O registro de procedimentos metodológicos em projetos de intervenção arquitetônica no patrimônio edificado: o caso de Natal-RN

In the midst of growing preservationist awareness, regarding methods of architectural intervention of buildings with a recognized heritage value, there are numerous approaches on how the original heritage value can be protected. However, can these intervention projects be differentiated? Is it possible to identify how they differ (if in fact they do) from an architectural project not related to preservation? Although there are numerous theoretical studies regarding methods utilized in architectonical projects, there appear to be a lack of studies focused on an architectural intervention exclusively focused on areas or edifications that have a recognized heritage value, thereby requiring a reflection on which methodological procedures in an architectonical project serve the purpose of the preservation of the historical aspects. This discussion is of even greater importance because, at the national level, some recent discussions on this type of architectural design seem arbitrary and lack methodological rigor. Therefore, this research attempts to focus equally on the theoretical-methodological practices of preservation as well as the architectural project methods. In an attempt to address these aspects, the focus of this research centers on the case studies of the intervention projects of the maritime passenger terminal of Natal (Terminal Marítimo de Passageriros de Natal), the old government hall (Palacio do Governo - EDTAM) and the old central hotel (Hotel Central) which are situated in the area known as the historic downtown of the city of Natal, within the federal heritage protection polygon. The analyses of these is intended to identify what methodological procedures were recorded in the final product (in the graphical representation of the architectural design and other documents) delivered to IPHAN / RN, the body responsible for review and approval of these architectural projects, noting whether such procedures appear, in some way, in the final product, and if an understanding of the complexity of preservation is evident. The analyses of these projects corroborate the hypothesis that there are unique characteristics, which must be addressed in the intervention project for preservation when compared to new project design. The main characteristic to be addressed is related to the very nature of the project. It is inherent in the dialectical relationship between the need to preserve (the identified heritage values) and the need to modernize (making adaptations to contemporary life). This relationship, denominated in this dissertation as "radical restraint", must, or at least should, guide the actions in the project as well as the technical analyses of the preservationist organization. However, this radical restriction appears more evident in the guidelines put forth by legislators than in the decisions of designers. These legislators require the presentation of documents, aimed at identifying and contextualizing intervention (Ordinance No. 420 of December 22, 2010), that grant (or should grant) assistance in the decision making process. It was evident in the analyses of these documents that there existed a disconnect between the documents produced and the decisions made in the project. This fact can be seen in the total absence of dialogue about theoretical-methodological preservationist principles, which, in our view, is an essential element of the methodological procedures of the intervention project needed to guide the legislative and project design discussions.

Escolarização de surdos no ensino médio em Natal/RN: vendo e ouvindo vozes

La Escuela Secundaria es la etapa final de la Educación Básica y su objetivo es profundizar los conocimientos adquiridos anteriormente, con vistas tanto a la continuidad de los estudios por parte de los alumnos como también a su formación profesional. Considerando el carácter excluyente y elitista de la Escuela Secundaria brasileña, solo recientemente las matrículas de los estudiantes sordos comienzan a ampliarse, y los profesores se deparan con el desafío de lidiar con ese tipo de discente en aulas regulares. Tanto la política de educación especial, desde una perspectiva inclusiva, como la Ley nº 10.436/2002 – reglamentada por el Decreto nº 5.626/2005 – posibilitaron un gran salto para la educación de los sordos en el país. La primera, por la defensa de una escuela atenta a las peculiaridades y demandas de sus discentes; la segunda, por reconocer la Lengua de Señas Brasileña como medio de comunicación y expresión legítimo de la comunidad de sordos y por indicar medidas que garanticen el derecho al acceso y al éxito escolar de la población sorda dentro de la escuela. Amparado en esas discusiones, este estudio tuvo como objetivo analizar el proceso de escolaridad de alumnos sordos de una Escuela Secundaria pública y estatal del municipio de Natal, Rio Grande do Norte. Se realizó un estudio de caso de tipo cualitativo. Los sujetos fueron tres discentes sordos que estaban terminando la Escuela Secundaria, una profesora de Portugués y dos intérpretes de Lengua de Señas Brasileña. Como procedimiento de investigación, se utilizaron entrevistas (grabadas en audio y video), observaciones y análisis de documentos. La participación de los sujetos sordos demandó cuidados éticos adicionales, tales como la traducción del Término de Consentimiento Libre y Aclarado y del guion de la entrevista a la Lengua de Señas Brasileña. Los resultados apuntan que el acceso y la permanencia en la escuela secundaria fueron garantizados, no obstante había poca participación en las clases y el aprendizaje de los contenidos escolares estaba comprometido. Había traductores/intérpretes de Lengua de Señas Brasileña, los cuales, sin embargo, solo iniciaron sus actividades tres meses después del comienzo del periodo lectivo. La profesora y los intérpretes no mantuvieron interacciones que facilitasen el aprendizaje o la participación de los estudiantes, quienes se encontraban siempre juntos y en un lugar determinado del aula, sin mayores interacciones con sus pares normo-oyentes. Los discentes sordos estaban terminando la Escuela Secundaria con edades superiores a 17-18 años, los cuales revelaron no tener perspectivas de continuidad en sus estudios o de inserción en el mercado laboral. Se concluye que la escolaridad de los alumnos sordos en la escuela investigada apunta a la necesidad de una reorganización curricular que atienda a las especificidades lingüísticas y sociales de esos estudiantes.

A reportagem nas rádios comerciais de Natal-RN

This thesis aims to investigate the space of radio reporting and production conditions in radio newscasts in commercial stations operating in modulated frequency (FM) in the city of Natal, Rio Grande do Norte. Through preliminary empirical observation, it was observed that this journalistic style (radio reportage) is hardly present in the schedule of local commercial radio stations, with a lack of in-depth news coverage. The research is based on the content broadcast in four daily radio news programs transmitted by commercial stations. It raises the hypothesis that the crisis that cuts across journalistic companies could be justified by the lack of financial funding in in-depth news reporting. The starting point for the case study (Yin, 2005) was a bibliographical research, for building a theoretical model of reference for the studied style, based on Prado (1989), Bespalhok (2006), Meditsch (2007), Lopes (2013) and Ferraretto (2014). The methodology also included listening to content broadcast during a week in the four analyzed news programs, participant observation and interviews with professionals who produce these programs. There were eight events with similar characteristics to radio reporting, all broadcast in just one of the analyzed programs. According to the interviewees, the format is rarely used because it would generate high businesses costs, which are prohibitively high for the stations. The research also inferred that besides the lack of entrepreneurial vision, there is accommodation of the professionals who could produce news stories even with little structure available. Finally, this work points out the need to invest more on local radio journalism to improve the quality of the information provided on commercial broadcasters in Natal and the training of journalism students to use radio's potential to maximum use.

Estudo da variabilidade da deriva vertical do plasma ionosférico sobre a região de Natal/RN, Fortaleza/CE e Cachoeira Paulista/SP para alguns casos de tempestades magnéticas de abril a setembro de 2000

In this work are presented the results of research on the variation of vertical plasma drift from the F layer that commonly occurs during the period close to the going down of the sun (between 21UT - 22UT), and consisting of an increase in the F layer in time of day and a drop at night on the cities of Natal / RN (The 33.7º, 5.6º S), Fortaleza / CE (38.45º O, 3.9º S) and Cachoeira Paulista / SP (45.0ºO, 22.7º S ). Thus, data was used (ionograms) virtual height t ( h' ) as a function of the frequency F for the layer of the ionosphere. These data were collected through ionossonda type CADI (Canadian Advanced Digital Ionosonde) to the cities of Natal and Fortaleza, and the Digisonde DPS to the town of Cachoeira Paulista. They considered only the data available 2000 maximum solar year. With the virtual height ( h' ) data reduced in the frequencies of 6MHz and 5MHz, the next step was to calculate. The results showed that the variability of the vertical drift rate F ionospheric layer periods of magnetic storms is related both to the penetration of the electric fields as the disturbance dynamo electric fields.
