A assistência técnica nos habitats do MST e o papel do arquiteto e urbanista

This dissertation is about Architect and town planner inserts in the technical support of the Rural establishment and of the possibilities of changes in their habitat. It also looks for its participation through the production of those spaces with or without its performance through two references cases, in Rio Grande do Norte , one called settlement Eldorado de Carajás and another one called Maria da Paz. At first the process represents the model that was adopted systematically by Incra until the middle of the year 2000 with the sub-contracting of their construction work through small companies. These standardized projects which are executed without registration in the system CONFEA/CREA without demand of professional authorship and of technical responsibility of the work. But the process taken place at Maria da Paz s area was configured as one of the first initiatives that stopped with those practices. Consolidated through a partnership among UFRN MST and INCRA/RN, the Architect s technical support and town planner brought new technician-scientific organization and execution of the soil parcels and its habitat. The participation of UFRN was done through a group of studies in land reform and Habitat (GERAH) being this author and coordinator of the methodological proposal, based on the regressive-progressive method and in the inclusion of the conflict as responsible of the ruptures and transductions both done by Henry Léfèbvre and in the research action approached by Carlos Brandão. Therefore it included the process of social learning and collective production of new knowledge and attitudes in relation to the environment in the process called as attended self management in spite of the transformations happened with this new agent s participation. The people re-located to the new areas that got involved in the process and finished their constructions reelaborating the daily practice of the collective effort passed to the self management without technical support. Years later the implantation of those two experiences our research verified that there is a positive image concerning the Architect and town planner, related, most of all to the conception of the activities, orientation and execution of constructions projects and of acceptance of those professionals to the processes of implementation of the Habitats of the Rural establishments. This dissertation analyses this form of performance, from and beyond these images trying to find the professional, specificities or methodological in such a way to demonstrate the importance of its insertion in the formulation and attendance of the more of 100.000 habitats of Rural establishments of the land reform of the country that correspond to most of the housing social interest in the country side

Corpo e escrita: linhas e entrelinhas da produção de conhecimento em sala de aula

Body and writing: Lines and between-lines of production of knowledge in the classroom it is an ethnographic research, longitudinal character, based on experience while experienced educator of the Escola Municipal Professor Amadeu Araújo, located in the city of Natal-RN, from which are made reflections about texts written by students who have distorted age/education level, in the process of literacy. Here as initial goal: to discuss the production of students writing as a process body, considering the record of experiences and the impressions they have made during the teaching process. We initially by a conception of phenomenological body, by understanding it in its complexity, a phenomenon that is made from its relationship with the world and with the Other. The records examined were produced between the year 2000 and 2005 involving writings of 106 students, constituting a universe of 136 texts, from which, delimited a corpus of 27 texts. The relevance with respect to the theme and recurrence in which they were detected, were up to elements that allowed a systematization methodology, defining the following units of analysis: Body, written in everyday; body, written and sexuality; body, written and enjoyment poetics; body, writing and other stories. We used the techniques of search, participant observation, based on the actions and interactions body expressed during the experiment and the analysis of documents that consisted of students in the texts and secondary sources, among them, the records of daily class, reports and projects developed, as well as reports of my pedagogical practice, as a researcher inserted in the investigative process. The experience developed, showed a writing school able to express nuances of human complexity, showing that learning is made in the action body, crossed by various forms of language and pointing to the relevance of a pedagogical work able to articulate the dialogue between the written and registrations body of the students, as subjects of learning

Um sistema para gestão do conhecimento em ameaças, vulnerabilidades e seus efeitos

Attacks to devices connected to networks are one of the main problems related to the confidentiality of sensitive data and the correct functioning of computer systems. In spite of the availability of tools and procedures that harden or prevent the occurrence of security incidents, network devices are successfully attacked using strategies applied in previous events. The lack of knowledge about scenarios in which these attacks occurred effectively contributes to the success of new attacks. The development of a tool that makes this kind of information available is, therefore, of great relevance. This work presents a support system to the management of corporate security for the storage, retrieval and help in constructing attack scenarios and related information. If an incident occurs in a corporation, an expert must access the system to store the specific attack scenario. This scenario, made available through controlled access, must be analyzed so that effective decisions or actions can be taken for similar cases. Besides the strategy used by the attacker, attack scenarios also exacerbate vulnerabilities in devices. The access to this kind of information contributes to an increased security level of a corporation's network devices and a decreased response time to occurring incidents

Desenvolvimento de um middleware para comunicação via web services e sua aplicação em sistemas de aquisição de dados industriais

The control of industrial processes has become increasingly complex due to variety of factory devices, quality requirement and market competition. Such complexity requires a large amount of data to be treated by the three levels of process control: field devices, control systems and management softwares. To use data effectively in each one of these levels is extremely important to industry. Many of today s industrial computer systems consist of distributed software systems written in a wide variety of programming languages and developed for specific platforms, so, even more companies apply a significant investment to maintain or even re-write their systems for different platforms. Furthermore, it is rare that a software system works in complete isolation. In industrial automation is common that, software had to interact with other systems on different machines and even written in different languages. Thus, interoperability is not just a long-term challenge, but also a current context requirement of industrial software production. This work aims to propose a middleware solution for communication over web service and presents an user case applying the solution developed to an integrated system for industrial data capture , allowing such data to be available simplified and platformindependent across the network

Prevalência de doença arterial obstrutiva periférica (DAOP) e alterações sensoriais em pacientes diabéticos tipo 2: impacto da DAOP sobre a qualidade de vida, nível de atividade física e composição corporal

Diabetes Mellitus (DM) affected approximately 171 million people in the world in the year 2000 as described by the World Health Organization (WHO). Because DM is a multisystem disease it can cause several complications especially those related to the cardiovascular system. The Peripheral Arterial Disease (PAD) of the lower limbs and the Diabetic Distal Symmetric Polyneuropathy (DDSP) can affect the DM patient causing consequences as the diabetic foot and eventually amputations. The main objective of this study was to determine the prevalence of PAD and sensorial impairment in 73 type 2 DM (DM2) patients and also assess the impact of PAD on quality of life, level of physical activity and body composition. For clinical assessment it was used: the ankle-brachial index (ABI); quantitative sensorial test for tactile sensibility (ST), pain (SD), vibration (SV); Achilles tendon reflex (RA); quality of life questionnaire (SF-36); modified Baecke physical activity questionnaire and bioelectric impedance. Prevalence of PAD in the studied population was 13.7%. ABI was inversely correlated to age (p=0,03; rhô= -0,26), diabetes duration (p=0,02; rhô= -0,28) and blood pressure (p= 0,0007; rhô= -0,33). There were lower scores for physical health summary on the SF-36 in DM2 patients; however, the presence of PAD predominantly mild did not significantly impact quality of life, body composition or physical activity level assessed by questionnaire. Fourteen patients (19.2%) present bilateral and symmetrical alterations in two or more sensorial tests compatible to DPN diagnosis. Abnormalities in ST, SD and SV were present in 27.3%, 24.6% and 8.2%; respectively. There was association of results from ST abnormalities with RA and mainly with SD, suggesting the importance of 10g monofilament use in DM2 routine assessment. In conclusion, the prevalence of PAD in subclinical DM2 was slightly higher compared to the general population and in agreement to previously published data in DM patients. The PAD severity was predominantly mild and still without repercussion on quality of life and body composition. Our study demonstrated a significant prevalence of both PAD and DPN in DM2 without previous diagnosis of these complications and indicates the necessity of early preventive and therapeutic interventions for this population

Nos tempos do blackout: cena musical, práticas urbanas e a ressignificação da Rua Chile, Natal-RN

This study aims to analyze the process of resignification of Chile Street, in Natal, from the development of a music scene in the late 1990s. Chile Street, as part of the Historic Centre of Natal, had its images constructed from the discursive practices and everyday life of its regular visitors, leading to a series of symbolic and imaging transformations throughout the twentieth century. Initially transformed into glamorous space as a result of urban actions of the new republic of Albuquerque Maranhão, in the early twentieth century, Ribeira and Chile Street, specifically, came to be seen as bohemian area, during the war time"; followed by a marginal phase, it was eventually transformed into the main rocker area of Natal, with the development of a musical scene in the second half of the 1990s. This music scene, its practices, economic interests, cultural events and identity ties created among their practitioners made Chile Street, "in the time of Blackout night club", an "alternative" space. As the historic centers, inserted in the logic of postmodern city marketing, both spaces are dynamic in their practices, as in their images, Chile Street also suffered changes in its meanings and symbols, around the year 2000 when the alternative-underground space became a pop space, where people from various parts of the city began attending its events and places, transforming it into a point of very heterogeneous sociability

A humanização no parto e no nascimento: os saberes e as práticas no contexto de uma maternidade pública brasileira

The practice of medicine related to the gestational processes tend to be organized according to the context and the place of work, being thus dependent of the conditions both social and economical, and of the physical structure and the functionality of the services. The high mortality rate in this process has diminished, since 1986, the study made by the World Health Organization (WHO) as to the technical aspects and the social inequalities that influence this situation in different geographical contexts. This culminated recommendations that proposed the reorientation of the dynamical practice of medicine, with a focus on the safety of maternities. Brazil adopted, in the year 2000, the suggestions of the OMS, emphasizing the humanization as the main reason for these actions. However, this discussion tends to not consider the problems caused by the social inequalities and the epidemiological and social conditionings that define the actions of the Unified Health System (Sistema Único de Saúde SUS). In this area, this research seeks to analyze the practices, cares taken, and the universal symbol that promotes and rewards the assistance to the birth of children by the SUS. Besides the analysis of the public documents that deal with this subject, an ethnographic study was developed in a maternity in Natal/RN, considered a model of humanization after receiving the Galba de Araújo prize in 2002. In this stage, the methodological strategies were observed, and the focus of the individual interviews with workers and users of this service. In the analysis of the data, it became evident that the different professional workers and women who gave birth, tend to show concern of the standards the delimit production and reproduction of the practice of medicine, as they favor the absence of a critical posture of the actions destined to the population. Besides this, if became evident that the institutional difficulties associated to the economical, cultural, and political problems also difficult the involvement and the reflection of the workers in favor of assisting changes of the process. There is also a utilization of a perspective prescriptive of humanization in the everyday life of the social workers, without reflection of its meaning. Some workers present, in their statements, a preoccupation with the social and economical aspects that affect the practice of medicine, and with the limitations of the humanization discourse that disarticulates the necessities of those involved in the process of formation, and soon tend to return to the discussion of humanization while a kind practice characterized by the minimization of the interventionist actions. Now the users of the system show themselves before the dynamic of the services, submitting themselves to what is offered while assistance, without questioning and/or reflecting about their usual shortages. Therefore, to think of changes in the know and do of the practice of medicine destined to the birth of children implies reflection on the quotidian production of these practices and of the social contexts that influence the process of assistance in the practice of medicine. Herein it would be possible to predict the appropriation, by different workers concerning their exasperations and necessities, making them active in the pursuit of their rights as citizens

BMMobile: uma linha de produtos para dimensionamento de bombeio mecânico em dispositivos móveis

With the increase of processing ability, storage and several kinds of communication existing such as Bluetooth, infrared, wireless networks, etc.., mobile devices are no longer only devices with specific function and have become tools with various functionalities. In the business field, the benefits that these kinds of devices can offer are considerable, because the portability allows tasks that previously could only be performed within the work environment, can be performed anywhere. In the context of oil exploration companies, mobile applications allow quick actions could be taken by petroleum engineers and technicians, using their mobile devices to avoid potential catastrophes like an unexpected stop or break of important equipment. In general, the configuration of equipment for oil extraction is performed on the work environment using computer systems in desktop platforms. After the obtained configuration, an employee goes to equipment to be configured and perform the modifications obtained on the use desktop system. This management process equipment for oil extraction takes long time and does not guarantee the maintenance in time to avoid problems. With the use of mobile devices, management and maintenance of equipment for oil extraction can be performed in a more agile time once it enables the engineer or technician oil can perform this configuration at the time and place where the request comes for example, near in the oil well where the equipment is located. The wide variety of mobile devices creates a big difficulty in developing mobile applications, since for one application can function in several types of devices, the application must be changed for each specific type of device, which makes the development quite costly. This paper defines and implements a software product line for designing sucker-rod pumping systems on mobile devices. This product line of software, called BMMobile, aims to produce products that are capable of performing calculations to determine the possible configurations for the equipment in the design suckerrod pumping, and managing the variabilities of the various products that can be generated. Besides, this work performs two evaluations. The first evaluation will verify the consistency of the products produced by the software product line. The second evaluation will verify the reuse of some products generated by SPL developed

STREAM-AP: um processo para sistematizar a escolha de padrões arquiteturais baseado em requisitos não-funcionais

The importance of non-functional requirements for computer systems is increasing. Satisfying these requirements requires special attention to the software architecture, since an unsuitable architecture introduces greater complexity in addition to the intrinsic complexity of the system. Some studies have shown that, despite requirements engineering and software architecture activities act on different aspects of development, they must be performed iteratively and intertwined to produce satisfactory software systems. The STREAM process presents a systematic approach to reduce the gap between requirements and architecture development, emphasizing the functional requirements, but using the non-functional requirements in an ad hoc way. However, non-functional requirements typically influence the system as a whole. Thus, the STREAM uses Architectural Patterns to refine the software architecture. These patterns are chosen by using non-functional requirements in an ad hoc way. This master thesis presents a process to improve STREAM in making the choice of architectural patterns systematic by using non-functional requirements, in order to guide the refinement of a software architecture

Coeficientes de incidência do dengue e sua relação com os diferenciais intra-urbanos segundo condições de vida no município do Natal, Rio Grande do Norte

This study sprang from the hypothesis that spatial variations in the morbidity rate for dengue fever within the municipality of Natal are related to intra-city socioeconomic and environmental variations. The objective of the project was to classify the different suburbs of Natal according to their living conditions and establish if there was any correlation between this classification and the incidence rate for dengue fever, with the aim of enabling public health planners to better control this disease. Data on population density, access to safe drinking water, rubbish collection, sewage disposal facilities, income level, education and the incidence of dengue fever during the years 2001 and 2003 was drawn from the Brazilian Demographic Census 2000 and from the Reportable Disease Notification System -SINAN. The study is presented here in the form of two papers, corresponding to the types of analysis performed: a classification of the urban districts into quartiles according to the living conditions which exist there, in the first article; and the incidence of dengue fever in each of these quartiles, in the second. By applying factorial analysis to the chosen socioeconomic and environmental indicators for the year 2000, a compound index of living condition (ICV) was obtained. On the basis of this index, it was possible to classify the urban districts into quartiles. On undertaking this grouping (paper 1), a heterogeneous distribution of living conditions was found across the city. As to the incidence rate for dengue fever (paper 2), it was discovered that the quartile identified as having the best living conditions presented incidence rates of 15.62 and 15.24 per 1000 inhabitants respectively in the years 2001 and 2003; whereas the quartile representing worst living conditions showed incidence rates of 25.10 and 10.32 for the comparable periods. The results suggest that dengue fever occurs in all social classes, and that its incidence is not related in any evident way to the chosen formula for living conditions

Análise do fluxo d’água na barragem Engenheiro Armando Ribeiro Gonçalves - Açu/RN

The solution of partial differential equation of seepage problems is difficult to find analytically, especially for situations that involve great complexity. To overcome this problem, software based on finite differences and finite elements are usually used. This work presents the use of a finite element software, the GEO5, to solve the seepage problem at a dam of very complex section, the dam Eng. Armando Ribeiro Gonçalves, which at the end of its construction suffered rupture of the upstream slope at the central dam and then went through a process of reconstruction and auscultation. The analyses were performed for the operating condition of the reservoir, with an established flow. A numerical model was developed based on the level readings of the reservoir water and their piezometric readings as a proposal for the evaluation and future behavior prediction of the dam on established flow conditions. The use of constitutive models with the aid of computer systems is reflected in a way to predict future risk situations so they can be prevented

Sistema inteligente para o processamento de imagens digitais intrabucais oclusais

Several are the areas in which digital images are used in solving day-to-day problems. In medicine the use of computer systems have improved the diagnosis and medical interpretations. In dentistry it’s not different, increasingly procedures assisted by computers have support dentists in their tasks. Set in this context, an area of dentistry known as public oral health is responsible for diagnosis and oral health treatment of a population. To this end, oral visual inspections are held in order to obtain oral health status information of a given population. From this collection of information, also known as epidemiological survey, the dentist can plan and evaluate taken actions for the different problems identified. This procedure has limiting factors, such as a limited number of qualified professionals to perform these tasks, different diagnoses interpretations among other factors. Given this context came the ideia of using intelligent systems techniques in supporting carrying out these tasks. Thus, it was proposed in this paper the development of an intelligent system able to segment, count and classify teeth from occlusal intraoral digital photographic images. The proposed system makes combined use of machine learning techniques and digital image processing. We first carried out a color-based segmentation on regions of interest, teeth and non teeth, in the images through the use of Support Vector Machine. After identifying these regions were used techniques based on morphological operators such as erosion and transformed watershed for counting and detecting the boundaries of the teeth, respectively. With the border detection of teeth was possible to calculate the Fourier descriptors for their shape and the position descriptors. Then the teeth were classified according to their types through the use of the SVM from the method one-against-all used in multiclass problem. The multiclass classification problem has been approached in two different ways. In the first approach we have considered three class types: molar, premolar and non teeth, while the second approach were considered five class types: molar, premolar, canine, incisor and non teeth. The system presented a satisfactory performance in the segmenting, counting and classification of teeth present in the images.
