Caracterização macro, meso e microscópica das estruturas frágeis do corpo arenítico conglomerático da região de Santana do Acaraú (CE) e seu embasamento circundante

The structural framework of the sedimentary basins usually plays an important role in oil prospects and reservoirs. Geometry, interconectivity and density of the brittle features developed during basin evolution could change the permo-porous character of the rocks involved in generation, migration and entrapment of fluid flow. Once the structural characterization of the reservois using only sub-surface data is not an easy task, many studies are focused in analogous outcrops trying to understand the main processes by which brittle tectonic is archieved. In the Santana do Acaraú region (Ceará state, NE Brazil) a pack of conglomeratic sandstone (here named CAC) has its geometry controlled mainly by NE trending faults, interpreted as related to reactivation of a precambrian Sobral Pedro II Lineament (LSP-II). Geological mapping of the CAC showed a major NE-SW trending synform developed before its complete lithification during a dextral transpression. This region was then selected to be studied in details in order of constrain the cretaceous deformation and so help the understanding the deformation of the basins along the brazilian equatorial margin. In order to characterize the brittle deformation in different scales, I study some attributes of the fractures and faults such as orientation, density, kinematic, opening, etc., through scanlines in satellite images, outcrops and thin sections. The study of the satellite images showed three main directions of the macrostructures, N-S, NE-SW and E-W. Two of theses features (N-S and E-W) are in aggreement with previous geophysical data. A bimodal pattern of the lineaments in the CAC´s basement rocks has been evidenciated by the NE and NW sets of structures obtained in the meso and microscale data. Besides the main dextral transpression two others later events, developed when the sediments were complety lithified, were recognized in the area. The interplay among theses events is responsible for the compartimentation of the CAC in several blocks along within some structural elements display diferents orientations. Based on the variation in the S0 orientation, the CAC can be subdivided in several domains. Dispite of the variations in orientations of the fractures/faults in the diferents domains, theses features, in the meso and microscopic scale, are concentrated in two sets (based on their trend) in all domains which show similar orientation of the S0 surface. Thus the S0 orientation was used to group the domains in three major sets: i) The first one is that where S0 is E-W oriented: the fractures are oriented mainly NE with the development of a secondary NW trending; ii) S0 trending NE: the fractures are concentrated mainly along the trend NW with a secondary concentration along the NE trend; iii) The third set, where S0 is NS the main fractures are NE and the secondary concentration is NW. Another analized parameter was the fault/fracture length. This attribute was studied in diferent scales trying to detect the upscale relationship. A terrain digital model (TDM) was built with the brittlel elements supperposed. This model enhanced a 3D visualization of the area as well as the spatial distribution of the fault/fractures. Finally, I believe that a better undertanding of the brittle tectonic affecting both CAC and its nearby basement will help the future interpretations of the tectonic envolved in the development of the sedimentary basins of the brazilian equatorial margin and their oil reservoirs and prospects, as for instance the Xaréu field in the Ceará basin, which subsurface data could be correlated with the surface ones

Humanização do atendimento à criança na atenção básica: visão dos profissionais

Objetivou-se compreender a humanização do atendimento à criança na Atenção Básica na visão dos profissionais. Estudo qualitativo, realizado em uma Unidade de Saúde da Família de Natal-RN, Brasil. Dezesseis profissionais responderam a um formulário contendo questões referentes ao atendimento à criança, à humanização e às práticas realizadas para humanizar o atendimento. Os dados foram categorizados por temas e analisados a partir dos princípios da Política Nacional de Humanização. Para os profissionais, humanizar o atendimento envolve acolher, escutar, aconselhar sobre o que está sendo realizado com a criança, valorizar a família, e tornar o sujeito ativo no atendimento, mesmo que de forma incipiente. A maioria dos profissionais descreveu atendimento que valorizava parte dos princípios da política de humanização, mesmo com dificuldades para implementá-los na rotina. Requer, portanto, estímulos e atualização dos profissionais para uma postura autocrítica sobre o atendimento

Gestão da cadeia de suprimento e vantagem competitiva: uma análise em setores industriais a partir da visão relacional

This work has as its main purpose to investigate the contribution of supply chain management in order to obtain competitive advantage by companies from the textile industry and from Ceará footwear industry, focusing its analysis mainly in the interorganizational relations (dyadic). For this, the theoretical referential contemplates different explanatory streams of the competitive advantage, detaching the relational perception of the resources theory, as well as, the main presuppositions of the supply chain management which culminates with the development of an analysis sample that runs the empirical study; the one which considers an expanded purpose of the supply chain which includes the government and the abetment institutions as institutional environment representatives. Besides supply chain management consideration as a competitive advantage source, the work also tried to identify other possible competitive advantage sources for the companies of the investigated sectors. It represents a study of multiple interpretive cases, having four cases as a total; meaning two cases in each one of the sectors, which used as a primary data collecting instrument a semi-structured interview schedule. Different methods were used for the data analysis, the content analysis and the constant comparison methods, the analytical procedure originated from the grounded theory research strategy, which were applied the Atlas/ti software recourse. Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

Marketing de relacionamento em um provedor de internet: um estudo comparativo que considera a visão gerencial e a percepção dos clientes

The current paper aims at analyzing customer retention in Internet provider services. For this study, we sought to understand what are the client's expectations regarding the services available and compare them with management perception in relation to the use of those services. Identifying the coherence level between the two points of view, management and client, it is possible to pinpoint how service is assessed in real conditions. Then, from this point on, a new vision can be implemented on available services, and new customer service strategies aiming at best serving to their expectation and need, can be rethought. The exploratory research was utilized. It was based on case study, and quantitative and qualitative methods were used. The quantitative method was done by applying the cluster technique with six variables of control derived from the six main services, whose definition was done through qualitative survey of the internal management team. Then, an structured interview with 443 clients, from a probabilistic sample of 800 costumers. The total number of active clients of the internet provider is of 10.677. Client perception in relation to services varied, if compared with the four services that were under the managerial metric method, this comparison showed a more positive evaluation than the real use of the service. Thus, it was observed that the value of each service available for the client depends on his/her perception of it, regardless of using or not the offered service. As a result, it is possible to understand which services offered by the company under study effectively contribute to a good client-company relationship, and the upkeep of those clients

Do modelo geométrico ao modelo físico: o tridimensional na educação do arquiteto e urbanista

In the teaching practice of architecture and urbanism in Brazil, educational legislation views modeling laboratories and workshops as an indispensable component of the infrastructure required for the good functioning of any architectural course of study. Although the development of information technology at the international level has created new possibilities for digital production of architectural models, research in this field being underway since the early 1990s, it is only from 2007 onwards that such technologies started to be incorporated into the teaching activity of architecture and urbanism in Brazil, through the pioneering experience at LAPAC/FEC/UNICAMP. It is therefore a recent experiment whose challenges can be highlighted through the following examples: (i) The implementation of digital prototyping laboratories in undergraduate courses of architecture and urbanism is still rare in Brazil; (ii) As a new developing field with few references and application to undergraduate programs, it is hard to define methodological procedures suitable for the pedagogical curricula already implemented or which have already been consolidated over the years; (iii) The new digital ways for producing tridimensional models are marked with specificities which make it difficult to fit them within the existing structures of model laboratories and workshops. Considering the above, the present thesis discusses the tridimensional model as a tool which may contribute to the development of students skills in perceiving, understanding and representing tridimensional space. Analysis is made of the relation between different forms of models and the teaching of architectural project, with emphasis on the design process. Starting from the conceptualization of the word model as it is used in architecture and urbanism, an attempt is made to identify types of tridimensional models used in the process of project conception, both through the traditional, manual way of model construction as well as through the digital ones. There is also an explanation on how new technologies for digital production of models through prototyping are being introduced in undergraduate academic programs of architecture and urbanism in Brazil, as well as a review of recent academic publications in this area. Based on the paradigm of reflective practice in teaching as designed by Schön (2000), the experiment applied in the research was undertaken in the integrated workshop courses of architectural project in the undergraduate program of architecture and urbanism at Universidade Federal do Rio Grande do Norte. Along the experiment, physical modeling, geometric modeling and digital prototyping are used in distinct moments of the design process with the purpose of observing the suitability of each model to the project s phases. The procedures used in the experiments are very close to the Action Research methodology in which the main purpose is the production of theoretical knowledge by improving the practice. The process was repeated during three consecutive semesters and reflection on the results which were achieved in each cycle helped enhancing the next one. As a result, a methodological procedure is proposed which consists of the definition of the Tridimensional Model as the integrating element for the contents studied in a specific academic period or semester. The teaching of Architectural Project as it is developed along the fifth academic period of the Architecture and Urbanism undergraduate program of UFRN is taken as a reference

Processos carioevolutivos na ordem tetraodontiformes: uma visão através de suas diferentes linhagens

Given the great diversity of fishes, the Order Tetraodontiformes stands to show genetic and morphological characteristics enough singular. The fishes of this order have a compact DNA which favors molecular studies, as well as comparisons with more basal species. Model of genome evolution, there are still many gaps in knowledge about their chromosomal patterns and how evolutionary rearrangements influence the marked variation in DNA content of this order. In view of this, we present cytogenetic analyzes of the species Acanthostracion quadricornis (Ostraciidae), A. polygonius (Ostraciidae) Melichthys niger (Balistidae) Cantherhines macrocerus (Monacanthidae) and C. pullus (Monacanthidae), Lagocephalus laevigatus, Colomesus psittacus and Canthigaster figueiredoi (Tetraodontidae), to contribute with cytogenetic data for this group. The analysis was performed by C-banding, Ag-RONs, coloring with base-specific fluorochromes DAPI-CMA3, restriction enzymes AluI, EcoRI, TaqI, PstI and HinfI and in situ hybridization with probes for ribosomal DNA 18S and 5S. The heterochromatic ultrastructure of A. quadricornis and A. polygonius revealed a outstanding heterochromatin content, which may indicate that the accumulation or loss of extensive heterochromatin content could be responsible for large variations in genomic content displayed in different Tetraodontiformes families. The species Cantherhines macrocerus, C. pullus (Monacanthidae) and Melichthys niger (Balistidae) shows a huge karyotypic similarity both numerically and structural. L. laevigatus showed similar cytogenetic features (2n = 44 and single RONs) to the species of the genus Takifugu, which reinforces the idea of their phylogenetic relationships. C. psittacus presented the highest diploid number described for the family (2n = 56) and large amount of HC, features that related with its sister family Diodontidae. Cytogenetic analysis in C. figueiredoi revealed heterochromatic polymorphisms, RONs multiple and Bs chromosomes. These events are rare in marine fishes, and are possibly associated with the strong restructuring and genomic reduction that this family has been suffered. These features, plus the morphological and molecular data suggests that these species share the same ancestral branch, with a possible monophyletic origin. In this study, new contributions to the knowledge of evolutionary patterns facing by Tetraodontiformes are provided and discussed under cytotaxonomyc, genomic and evolutionary perspectives.

A formação do pedagogo-professor no curso de pedagogia: limites e possibilidades na visão de professores formados no campus avançado de Patu da UERN

The inconclusive policies regarding the teaching background, specifically the Pedagogy Course, whose National Curricular Directives DCN were ratified by the Ministry of Education on April 4th 2006, have been causing protest from the various forces within the scope of the university, specifically in the Pedagogy Departments in which, through their professionals, express the several stands about the pedagogue profile, his/her professional acting field and a curriculum that meets the background needs of this professional. This paper tried to assess, from the viewpoint of the student who graduated from the Pedagogy Course and who acts in classroom in the first years of the Elementary School, to what extent this course meets the background needs of the professional who works as teacher. In specific terms it was this paper's objective to identify the most important background needs of teachers who graduated in Pedagogy, who act in the first years of the Elementary School; To list the contributions and limitations of the Pedagogy Course of CAJIM/UERN in the teachers' background, outlined by the graduates of the course; to raise suggestions for the improvement of the teachers' background in the Pedagogy Course of the CAJIM/UERN. In order to turn these objectives viable we opted for the qualitative approach in research, more precisely for the case study methodology, from which we used as instruments for the execution of the field work the observation in classrooms, semi-structured interviews which became the main instrument used for the data construction and analysis. The data analysis process took place through the content analysis technique based in Bardin (2000). The theoretical line is based on the studies from Schön (2000), Nóvoa (1997), Perrenoud (1993), Alarcão (2003), Ramalho (2003) we also used the National Curricular Directives which serve as current Parameter for the Pedagogy courses. The study indicated that the Pedagogy Course contributed for the personal and professional enrichment, however, difficulties in the theory-practice articulation are still present in the everyday life. The theoretical knowledge assimilated, though represent increments to the professional practice, are not enough to enable a pedagogical practice with excellence. There is a need to consider a curriculum in a dialectic perspective, configurator of social and cultural practices sustained by the reasoning as praxis, thus it must not be seen solely in a theoretical plan, mas as a process that builds itself between the acting and the reasoning.

Uma visão local de um projeto nacional: o curso mídias na educação

The essay "A local view of a national project: the course in Media Education" presents a research aimed at analyzing how the course Media in Education is being implemented by both Federal University of Rio Grande do Norte and State University of Rio Grande do Norte, with the intention of pointing out weaknesses in its use, which should be resolved in order to contribute to the design of other courses along these lines. Therefore, we performed a survey in which data collection, have used open questionnaires available in online pages created specifically for this purpose and administered to alumni and former participants, course participants and tutors from the two universities involved in the research. Through these questionnaires, we identified, especially, those aspects that negatively affect the provision of course related to the student's profile, the virtual learning environment where the course is hosted, the meetings, the contents and activities, the mentoring and the dropout, and the changes to improve the implementation of the course. The research collaborators are professors of public basic education. To understand the continuing education of teachers, conducted through distance education, using the virtual learning environment, we contextualize this from the nineties, in the context of the Brazilian educational reform took place in that decade. The Media in Education course is presented as a different proposition because it allows teachers to follow different pathways, materialized in the learning cycle. At the end of the study, we conclude that the implementation of this course, of the RN, the conditions for dialogue to happen, specifically, are not given

O acolhimento no ambulatório de um hospital universitário na visão de usuários

This present study of quantitative/qualitative approach, aims to analyze the outpatient care at the Hospital Universitário Onofre Lopes (HUOL), and, having as guide, the reception of the user. In this regard were invited and interviewed 20 users. Besides the interviews, conducted in a period of 45 days, in this same period of time was used a field diary for more significant notes of observations more significant. In the analysis, we drafted the socio-demographic profile of the group and identified their main complaints, problems and suggestions. For this, we have built graphics, tables and pictures, in addition to standing out their testimony, as a resource for better understanding of the subjective aspects. The theoretical reference consisted of documents from the Ministry of Health about the reception and humanization, and the studies of Merhy, Franco, Pinheiro, Matumoto, Mariotti, Teixeira, among others. The results show the ambulatory of HUOL as a privileged space and of credibility, where users commonly, find answers to their problems. However, these same users were unanimous in saying the difficulties they face in obtaining consultations, from the basic unit, until the hospital. Regarding the service, although they feel satisfied as for the assistance received, they list a series of problems, of structural relationship order: lack of visual signalling, information, wheelchairs, hygiene, in the waiting rooms that offer some comfort, besides the inattention of some professionals. In summary, in the study, undertaken now, we cannot say that there is in the reality studied, the reception, in its full meaning, but the HUOL as hospital-school, has all the potential to accomplish it

Articulação ensino/serviço na visão de discentes de enfermagem

It is a descriptive study with a qualitative approach aimed at understanding the impact of the teaching / service between the Nursing College of University of Rio Grande do Norte (FAEN / UERN) and health services in the city of Mossoró / RN on student s learning process. Hence, it was inquired to rescue and over-elaborate the trajectories experienced by students who were graduating in the year of 2009 the Nursing graduation course. It was used, as guidance tool a questionary with both open and objective questions to support the data collection. The data analysis was accomplished based on the precepts proposed by Bardin. The research revealed a clear need of bond establishments with the involvement of the students on services as well as professionals inserted on Academy, in a way that knowledge can be built collectively and the difficulties can be eased.

O projeto politico pedagógico de enfermagem e o sistema único de saúde: a visão de discentes

This research aims to analyze, in the view of students, the pedagogic project of undergraduate nursing course, of UFRN, and its articulation with the SUS, in an attempt to understand the issues that permeate the teaching and learning of nursing. This is a qualitative study that used the focus group technique as a tool to collect empirical data. There were three meetings, where we had the collaboration of 23 graduating students from the eighth period of the semester 2009.1. For the analysis of information, we use a theoretical framework based on curriculum guidelines and basic principles of the SUS, making the analogy of the results with the metaphor of Greek mythology, Ariadne's thread, in dialogue with authors who discuss education as a transformative practice. Thus, the texture of the yarn was built of five thematic fields: joint the pedagogic project with the SUS; the teaching/service and theory/practice relation; interdisciplinarity or transdisciplinarity; didactic/methodological and relational approaches; and co-participation of students in the pedagogic project. According to the discussions, we find many difficulties in the teaching and learning process of undergraduate nursing in UFRN to strengthen the SUS, including: dislocation of educational institutions with services, professionals, managers and community; dichotomy between theory and practice; reality of services as a learning field and working process in health; posture adopted by professionals, teachers and other subjects included in the process of health education; decontextualization and fragmentation of teaching with the practice in health and nursing; excessive use of very illustrative methodologies, but little problem-solving; difficult and precarious situation in the relations between teachers and between teachers/students, regarding the acceptance of differences; absence of participation of students in the evaluation process and conduct of the educational project in progress. In this sense, we understand the need an auto-reflexive act of teaching and conducting collective pedagogical course with a view to achieving the SUS. Thus, it is necessary to support practices motivated by the polyphonic dialogue and the exercise of symbiosis and autopoiesis of subjects/actors jointly responsible for the ongoing process of learning for life.

A violência no contexto de um serviço de urgência: análise do processo de cuidar na visão das vítimas e profissionais de saúde em Natal/RN

Exploratory descriptive study, with a quantitative approach and prospective data, performed in Pronto Socorro Clóvis Sarinho (PSCS), in Natal/RN, aiming to analyze care given by the nursing and medical staff to victims of violence attended to in an emergency hospital in Natal/RN; to identify care given by the nursing and medical staff as viewed by the victims; to compare data observed during the process of care with the victim s view on the care given by the nursing and medical staff; to identify the existing knowledge on violence and the process of caring for victims and its relation with prejudice; to identify obstacles and perspectives for prevention during the process of caring for victims in the emergency services. The population consisted of 97 physicians, 16 nurses, 75 nursing technicians and assistants and 365 victims of violence, with data collected from April to May 2009. Out of 188 professionals, 52.1% are female; 32% were aged 41 to 50; 99.5% had given care to a victim of violence; 90.4% reported to have given care to patients under custody; among these, 17.3% felt prejudice; 55.3% stated they don t provide different care for assaulted victims and assailants, however 44.7% stated they do; 86.7% feel their workplace is unsafe; 61.7% denied the existence of any obstacle and 38.3% reported the existence of obstacles; among these, 26.1% referred to inadequate facilities; 37.8% believe reinforcing security and professional training are the main solutions. Among the 365 researched violence victims, 82.2% were assaulted; male (69.6%); aged 18 to 24 (24.9%); hailing from the Greater Natal area (89.9%); on 19.7% the event happened on Saturday; during the night (48.8%); victim of physical assault (61.4%); produced by body force (27.7%); 24.4% were injured in the head and neck. 57% had used some drug, among which alcohol was predominant (75.5%). On 621 observations performed during the victim care process, when compared to the report of assaulted victims, there was a statistical difference, at 5% significance level, regarding reception, resistance from the professionals, questioning about the violent event, providing of guidance, interaction with the patient and the understanding of receiving proper care, and care resolution. In comparisons involving the observed and the assailant victims reports, there was a statistical difference regarding the resence of resistance from the professionals, performance of necessary procedures and the nteraction with the patient and the understanding of receiving proper care and 58.1% reported the nursing team was the one that provided the best care. We conclude that professionals had lready given care to assailant patients, acknowledge the importance of knowing how the vent took place and acquired this preparation during their practice. The most often referred bstacles that hinder assistance were: inadequate facilities, material deficit and lack of rofessional preparation. As solutions for these problems, they cited the reinforcement of ecurity and professional training

Tuberculose: conhecimentos, representações sociais e experiências da doença na visão do portador

Tuberculosis is considered one of the most ancient human diseases, cases were registered 3900 years before Christ, and it is currently regarded as a serious public health problem in the world due to several factors such as income mismanagement, precarious standard of life and some sort of prejudice comprised by the word tuberculosis. Taking this into consideration, it was developed a descriptive and exploratory study aiming at analyzing the social representations of tuberculosis made by its patient from the Unidades de Saúde da Família (Family Health Units a public health program) in Campina Grande City PB, in relation to the decentralization of the policies that administrate the disease. It was interviewed 34 tuberculosis patient that were being treated from 2007 to 2008. The age group of the interviewees varied from 10 to 60 years old, but most of them were between 36 and 60 years old (58,8%, n=20), some were young adult and adult (21 35 years old), with 11 (32,3%) respondents, and, less frequent, children and teenagers (11 20 years old), with 03 (8,8%) participants. Data was collected through semi-structured interview. The questions that guided the research were elaborated based on the operational recommendations of DOTS strategy; that is: access to laboratory examinations; medication guarantee; directly observed treatment. Besides that, the experiences of the patient were considered in their relation with the family and the different social groups. The analysis of the discursive material was submitted to the Analyse Lexicale par Context d un Ensemble de Segments de Texte software - ALCESTE 4.7. Data interpretation showed five categories for the social representations of the tuberculosis patient that participated in DOTS strategy: 1) the accessibility of the health assistance service; 2) the patient perspective of the disease; 3) the change in the operation of the productive life; 4) the signals and symptoms of the tuberculosis disease; 5) the rearrangement and mechanisms used to face the disease. The Central Nucleus reveals that tuberculosis is a transmissible disease that can be prevented by people through educational practices, health promotion, active search for symptomatic respiratory and control of the carriers communication; these mechanisms should be incorporated to the routine of all participants of the family health groups. The Intermediate Elements, based on quotidian life, as well as the individual experiences of the tuberculosis patient, reveals prejudiced attitude and beliefs that lead to isolation and restriction of interpersonal relationship. Peripheral Elements were constituted by themes that showed the patient feelings of indignation because of the social barriers they had to face in the Family Health Units during the treatment. These elements demonstrate a negative perspective of the representation concerning the accessibility, i.e. inadequate structure of the health service; long distance to the Health Centre, this factormakes it difficult for the patient to continue the treatment; scheduling delay; and limited service regarding other requests (doctor, dentist etc). One expects to contribute for the construction of a new perspective of the health question between the different agents who make the assistencial institutions and formation of professionals, either in central or local scope
