O Plano Diretor como instrumento de gestão da cidade: o caso da cidade de Fortaleza/CE

According to article 182 of the Brazilian Federal Constitution, cities should perform social function, what brings the concept that the city should be a place for one to live well. For that to happen, it should be well administered by its public managers. However, so that there is a sound administration, one that really performs that social function, there must be, first, an efficient planning. We understand that such a thing occurs when the master plan is the main planning instrument of a city and serves as basis for its administration. We notice, however, that in most of the cities the master plan is formulated as a law that regulates urban planning but that both the population and the government most of the times are not aware of its importance concerning the relevant issues related to municipal administration, such as its relationship with the economy, taxation, the social issue, land use regulation, and, in summary, with all the aspects that constitute and that a municipal government should manage in the best possible way. One also knows that, in general, the attempt of city planning has always been connected to the duration of a mandate and that way public managers many times implement restricted measures aiming to just attain a political-electoral objective and publicizing their administration. That implies actions and works that in some cases have negative impacts or ones that cannot be removed from the cities. This study intends to show that the master plan should be the planning instrument guiding the municipal administration but that, however, what we note is a lack of connection between that instrument and the government guidelines of the municipal managers. In order to study what happens to the cities that have a planning which is not taken into account in its administration, we will use the city of Fortaleza, capital of the State of Ceará as a case study. Historically, in Fortaleza the public managers have seldom decided to administer the city in according to the master plans developed for it. We should emphasize that planning begins in the city quite late and until the current days it is being substituted by temporary measures. Through the analysis of the planning process and of the urban management of the city of Fortaleza, especially the master plans predicted since 1933, we explain that if such plans had been implemented, they could have been important tools for its administration to attain a social function, becoming therefore a place for one to live well

Entre o cartão-postal e a cidade real: um estudo sobre paisagem e produção imobiliária em Natal/RN

Recent studies concerning the landscape have investigated the most important activities that contribute for its modification and have tried to better understand the society through the marks left by its quotidian. It is understood that singular landscapes constitute the cultural patrimonies of the cities, once they are part of the daily life of the citizens and are present in their social representations. Some contemporary authors defend the preservation of the natural and urban landscape trying, specially, to keep its importance for the local population. Natal is a city where the ambient qualities are well defined and known by the beauty of the area where it is located. Situated just between a river and the sea, the city grew following its geographic characteristics. The Potengi River, the Atlantic Ocean and the vast dunes ecosystem represented natural limits to the urban expansion; at the same time they have favored the development of a landscape pattern marked by the dialectic between the natural elements and the human interventions. However, this relationship changed after the intensification of the high rising development process that took place since the 1960s. The urban legislation tried to preserve the features of the local landscape delimiting Areas for Controlling Building High , destined to protect the scenic value of some parts of the city. On the other hand, the civil construction sector has made constant pressure in sense to abolish or to modify this legal instrument, aiming profits that have increased, in the 1990s, because of the consumption and the qualification of the urban space for tourist activities. It is necessary the raising of new elements to stimulate the quarrel about the landscape preservation, the process of the urban space production and the best way for the legislation implementation. This work tries to raise elements about the subject at local level, in sense to use Natal City experience to contribute for the formulation of indicators to raise the question about the lack of measure for subjective values, for example the cultural and affective value of the landscape. The natural elements inserted in the urban profile, represent strong visual references and supply identity to the town; they are part of the collective imaginary and are detached in the social context of the city. Then, why the preservation of the landscape, that estimates the improvement in the quality of life, is not enough to justify the controlling building high already previewed as part of Natal City Legislation? These questions send us to the approach of the landscape, as a community patrimony, alerting that some of its significant esthetics attributes must be preserved as a legacy for the future generations

Feiras livres : cidades de um só dia, aprendizados para a vida inteira

La tesis problematiza constelaciones creativas de saberes marcados por múltiples subjetividades en un espacio singular de las ciudades: la feria libre. Lugar de cambios financieros, pero también afectivos, simbólicos y míticos, ese espacio se mantiene al lado de los lugares comerciales asépticos y climatizados como son los supermercados e hipermercados de los espacios urbanos y de las metrópolis. Las ferias, por su carácter itinerante y sus personajes nómades modernos, son capaces de suscitar múltiples observaciones, divagaciones, afecciones y construcción de conocimientos. En la feria libre del barrio de Alecrim en la ciudad de Natal-RN/Brasil, principal contexto de referencia de esta investigación, en medio de tantos estímulos movilizadores de los órganos de los sentidos, salta a los ojos el elevado contingente de niños y adolescentes ejerciendo las múltiples actividades laborales. En Brasil el trabajo infantil es encajado en prohibiciones prescritas por leyes que recubren singularidades. Sin la pretensión de negar la importancia de tales convenciones y reglas, las reflexiones aquí puestas ultrapasan las amarras homogeneizantes del discurso oficial instituido de prohibición, problematizando a partir de la feria la idea de una caótica y pulsante aula al aire libre en la cual se construyen saberes más próximos de una lógica del sensible (Claude Lévi-Strauss). La feria es un laboratorio de construcción de conocimientos pertinentes (Edgar Morin), aquellos que religan fenómeno y contexto sin oponer manipulación y tiempo real de aplicabilidad de los saberes construidos. En esa escuela sin paredes, puertas, ventanas, cuadros negros o programas, los saberes de la tradición (Conceição Almeida) son probados y compartidos por niños y adolescentes que viven constantemente con un tipo de cambio de bienes y palabras en permanente construcción. En los puestos de la feria y para más allá de ellos encontramos sujetos híbridos (Bruno Latour) que se estructuran por medio de mecanismos creativos capaces de hacerlos navegar en las incertidumbres caóticas de sus vidas. Los aprendizajes de la feria fueron o son la pulsión de reinvención de esos sujetos aparentemente encarcelados en el conformismo como fatalidad última, portadores de historias embarazadas de simbologías tristes y felices que exponen la cara de un humano en permanente combustión, construcción e incertidumbre

Cidades e turismo sustentável:a cooperação interinstitucional no Conselho de Desenvolvimento do Turismo do Pólo Costa das Dunas/RN

It treats tourism as part of the places urban development dynamics and the touristic urbanization process as a strategy of cities international competitiveness strengthen, detaching institucional agents role as promoters of this process. It aims to understand how happens the interinstitucional cooperation existing between the agents (Estate, private initiative and third sector) that composes the Development Council of Pólo Costa das Dunas/RN, littoral potiguar region, where are invested the resources deriving from the Program of Development of Tourism in the northeast of Brazil (PRODETUR/NE). Making use of economy referencials, urban sociology and urban geography, as a possibility of a more consistent theoretical construction, capable to accomplish the sustainable development and sustainable tourism concepts amplitude, this work brings out an experience of interinstitucional cooperation, where it glimpses itself the possibility of implementation of a alternative development model, based on the sustainability principles

As cidades medias no desenvolvimento regional: um estudo sobre Pau dos Ferros (RN)

Esta tese versa sobre as cidades médias no atual contexto do desenvolvimento urbano brasileiro e nordestino. Na região Nordeste, o processo de urbanização foi lento, atomizado, geográfico e economicamente disperso, o que resultou numa rede urbana truncada, constituída principalmente por suas nove capitais regionais e cerca de duas dezenas de cidades de porte médio, em sua maioria, interiorizadas. Foi a partir dessa rede urbana nordestina interiorizada que nos propomos a estudar Pau dos Ferros, no Rio Grande do Norte e o papel que ela desempenha na rede urbana nordestina e potiguar. Compreender os determinantes da produção do espaço urbano-regional de Pau dos Ferros que o caracterizam como cidade média, com fins a refletir sobre o seu papel no desenvolvimento regional foi o objetivo geral desta pesquisa. Nossa hipótese é que, a despeito de um contingente populacional pequeno, Pau dos Ferros vem desempenhando na rede urbana do Nordeste e do Rio Grande do Norte as funções de cidade média, particularmente, na oferta dos serviços de educação superior e saúde, além da oferta de empregos, notadamente no comércio e nos serviços públicos, o que nos permitiu tratá-la à priori, a partir do conceito de cidade (inter) média. Para esta investigação, partimos da proposta de estudo e do pensamento de autores como Faria (1978), Benko (1999) e Brandão (2007), os quais propõem o estudo do urbano a partir de situações concretas que permitam compreender os fenomenos em sua múltiplas causalidades. Dessa forma, o fio condutor desta análise foi o modo como vem se reconfigurando as cidades médias e como essa reconfiguração tem afetado de diferentes formas as relações entre as cidades e entre as cidades e as regiões. Os resultados das análises apontaram que os investimentos públicos em saúde e educação têm contribuído para a atração de investimentos privados em suas respectivas áreas, e também em outras, o que tem ajudado a dinamizar a economia da cidade, inclusive modificado parcialmente sua estrutura ocupacional. Pau dos Ferros se destacou como um polo comercial e de serviços na rede urbana potiguar, formando um outlier no Alto Oeste, organizando uma bacia de empregos na sua área de influência que constatamos ser composta por 55 municípios do RN, CE e PB. Ao se consolidar como polo regional na oferta dos serviços de saúde e de educação superior, ampliou-se o fluxo de pessoas que realizam movimento pendular para trabalho e estudo. Em síntese, constatou-se que, a despeito do pequeno contingente populacional, a configuração urbano-regional de Pau dos Ferros, tanto em termos de sua dinâmica urbana, como de sua abrangência regional, fazem dela uma cidade média na rede urbana nordestina interiorizada

Desenvolvimento Urbano e Cidades Inclusivas: Estudo Analítico do Princípio Constitucional da Função Social das Cidades

The reality of Latin America points out that the industrialization and urbanization are complementary processes associated each other. Thus, by consequence of the demographic growth, observes the aggravation of an urbanization completely disordered and without infrastructure capable of guaranteeing rights and basic services to the population. In parallel, the dissemination of information, the valorization of human dignity, promoted by social welfare, and expectations of consumption aggravates the tensions among social actors, leading to the Theory of the Right to Development to worry about the (re)construction of cities. Before this reality, the Federal Constitution of 1988 proposed a participatory urban policy, grounded in the ideal of confrontation of social exclusion of a more comprehensive, represented by the principle of the social function of cities, which must be stratified into four inclusion´s central axes, namely: the social in the strict sense, the economic, the cultural and the policy. The Analysis of each of these dimensions, keeping the focus on reality and the Brazilian legal system, composes specific objectives of this work. Thus, through deductive research, with use of technique bibliographical and interdisciplinary, this dissertation aims to make connections between social function and development, proposing an analytical concept for the proposing an analytical concept for the principle of social function of cities, through the study of its basic elements. With this, purports to demonstrate how results, firstly, that the juridical study, to fully understand the process of marginalization, must maintain multidisciplinary perspective, own social sciences. Also aims to demonstrate that the dimensions of inclusion are formed by fundamental rights, individual and collective, of liberties and of social guarantees and that without respect to all of them there is no way to talk about implementation of urban development and nor, consequently, about inclusive cities. At the end, after checking the main legal instruments of urban policy that emphasize the community participation, provided for in the Statute of the Cities, and that potentiate the breakup of the circles of exclusion, the work want contribute to the clarification and the awaken to the importance of a new perspective democratic of development in the country, grounded in the appreciation of the individual for realization of modern management, decentralized and that, therefore, inserts the effective participation of urban communities in the acting of the State

Direito à moradia em cidades sustentáveis: parâmetros de políticas públicas habitacionais Natal 2013

The right to housing is included in several international human rights instruments and in Brazilian legal system integrates the constitutional catalog of fundamental social rights (art. 6) and urban development policy (art. 182 and 183). Besides, it is for all federative governments its effectiveness by building programs and improvement of housing conditions and sanitation (art. 23, IX), which justifies the investment in urban planning and public policy of housing affordability because they are tools for achieving this right. Newer strategies in this area have been based on tax incentives, combined with the mortgage as a way to induce the construction of new housing units or reform those in a precarious situation. However, there is still a deficit households and environmental soundness, compounded with the formation of informal settlements. Consequently, we need constant reflections on the issue, in order to identify parameters that actually guide their housing policies in order to meet the constitutional social functions of the city and ensure well-begins of its citizens (art. 182). On the other hand, the intervention of the government in this segment can not only see the availability of the home itself, but also the quality of your extension or surroundings, observing aspects related to environmental sanitation, urban mobility, leisure and services essential health, education and social assistance. It appears that the smoothness and efficiency of a housing policy condition to the concept of adequate housing, in other words, structurally safe, comfortable and environmentally legally legitimate, viable from the extensive coordination with other public policies. Only to compliance with this guideline, it is possible to realize the right to housing in sustainable cities

A evolução do emprego formal industrial nas cidades médias do estado do Ceará (Juazeiro do Norte, Crato e Sobral) no período de 1990 a 2010

The work consists in a discussion of the evolution of formal employment in the industrial cities of Ceará state averages from 1990 to 2010, since this period was marked by important changes. It is emphasized that in order to achieve this aim, the present study was based on a survey of relevant literature on the subject, as well as the use of the Annual Report of Social Information (RAIS), published by the Ministry of Labour and Employment (MTE) and the Brazilian Institute of Geography and Statistics (IBGE). The central question to be considered in this study is how we evolved formal employment industry in medium-sized cities (Juazeiro do Norte, Crato and Sobral) of Ceará? The assumption that guides this work is that given the economic policies of the 1990 and 2000 these policies encouraged the relocation, thus implying significant growth in the formal manufacturing employment in these cities. Regarding the results obtained in the survey, it was found that the industrial sector of these cities, showed considerable dynamism in what refers to the expansion of establishments. When observed in percentage terms medium-sized cities (345.5%) had the highest growth in number of establishments in the 1990s with rates higher than the Northeast region (285.9%) and Brazil (167.5%). The highlight was the city of Juazeiro, with the highest concentration of micro and small footwear companies in the state. Regarding the number of formal jobs created in medium-sized cities, it went from 6.596 in 1990 to 41.660 million formal jobs in 2010, with a growth rate of 532%. The sector contributed most to employment generation was the footwear. Although the levels of minimum wages, the 1990 recorded the lowest levels. In the 2000, there were real gains in levels of minimum wages in all cities, however, it may be noted that over the decades there has been significant momentum. However, this momentum was not enough to prevent the end of the study period CMs-Ceará present low wages

Currículo e arquitetura escolar: concepções de professoras e equipe gestora do Colégio Nossa Senhora das Neves-Natal-RN

The present study aims to investigate the conceptions of teachers and management team of the Colégio Nossa Senhora das Neves - Natal / RN about curriculum, school architecture and possible relationships established between these components. To develop the study, we rely on the theoretical contributions of Viñao Frago (2001), Escolano (2001); Benconstta (2005), among others, about the architecture school, and with regard to curriculum, ancoramo us in theoretical reflections Silva (2000, 2006, 2008). We assume that the school place is a social construct and as such, reflects the interests of certain groups, to organize, establish ways to condition their unctions and uses. In this space, people's lives is planned, both those who work there, as those who study there. Thus, the architecture school promotes, through representations, signs, symbols and shapes, certain charges that impact the ways of being and acting subjects by establishing appropriation and expropriation of rights and legitimate forms of inclusion and exclusion. Thus, it is an expression of power. A power that is expressed in the form of lead the way people should behave in a certain space. Clarity on these aspects of the architecture school is important, since in the same way that the opinion of several experts is important to discuss the adequacy of school architecture (environmentalists, architects, engineers, planners), the / the teacher / and the / as managers / must also meet the educational nature of the architecture school, so as to present its share of contribution in order to make the post-school conducive to learning multiple. From this perspective, we analyze the concepts of four teachers and eight individuals who are part of the management team of the CNSN, whose views were seized through participant observation, semi-structured interviews and documentary analysis. The construction of the data indicated levels of conceptual curriculum varied, ranging from those rooted in traditional theories of curriculum as those regarding the curriculum tied to discursive and contextual aspects. The conceptions of architecture school, predominantly focused on the aspects of the architecture school materials and most established subject, differently, relations between curriculum and school architecture

H-N2N : uma arquitetura hierárquica escalável para ambientes de realidade mista de grande porte

In this work, we propose a solution to solve the scalability problem found in collaborative, virtual and mixed reality environments of large scale, that use the hierarchical client-server model. Basically, we use a hierarchy of servers. When the capacity of a server is reached, a new server is created as a sun of the first one, and the system load is distributed between them (father and sun). We propose efficient tools and techniques for solving problems inherent to client-server model, as the definition of clusters of users, distribution and redistribution of users through the servers, and some mixing and filtering operations, that are necessary to reduce flow between servers. The new model was tested, in simulation, emulation and in interactive applications that were implemented. The results of these experimentations show enhancements in the traditional, previous models indicating the usability of the proposed in problems of all-to-all communications. This is the case of interactive games and other applications devoted to Internet (including multi-user environments) and interactive applications of the Brazilian Digital Television System, to be developed by the research group. Keywords: large scale virtual environments, interactive digital tv, distributed

Uma arquitetura baseada em agentes para configuração dinâmica de aplicações inteligentes em ambiente foundation fieldbus

The industrial automation is directly linked to the development of information tecnology. Better hardware solutions, as well as improvements in software development methodologies make possible the rapid growth of the productive process control. In this thesis, we propose an architecture that will allow the joining of two technologies in hardware (industrial network) and software field (multiagent systems). The objective of this proposal is to join those technologies in a multiagent architecture to allow control strategies implementations in to field devices. With this, we intend develop an agents architecture to detect and solve problems which may occur in the industrial network environment. Our work ally machine learning with industrial context, become proposed multiagent architecture adaptable to unfamiliar or unexpected production environment. We used neural networks and presented an allocation strategies of these networks in industrial network field devices. With this we intend to improve decision support at plant level and allow operations human intervention independent

Arquitetura inteligente fuzzy para monitoramento de sinais vitais de pacientes: um estudo de caso em UTI

The area of the hospital automation has been the subject a lot of research, addressing relevant issues which can be automated, such as: management and control (electronic medical records, scheduling appointments, hospitalization, among others); communication (tracking patients, staff and materials), development of medical, hospital and laboratory equipment; monitoring (patients, staff and materials); and aid to medical diagnosis (according to each speciality). This thesis presents an architecture for a patient monitoring and alert systems. This architecture is based on intelligent systems techniques and is applied in hospital automation, specifically in the Intensive Care Unit (ICU) for the patient monitoring in hospital environment. The main goal of this architecture is to transform the multiparameter monitor data into useful information, through the knowledge of specialists and normal parameters of vital signs based on fuzzy logic that allows to extract information about the clinical condition of ICU patients and give a pre-diagnosis. Finally, alerts are dispatched to medical professionals in case any abnormality is found during monitoring. After the validation of the architecture, the fuzzy logic inferences were applied to the trainning and validation of an Artificial Neural Network for classification of the cases that were validated a priori with the fuzzy system

Uma arquitetura P2P baseada na hierarquia do endereçamento IP com roteamento unificado

There are some approaches that take advantage of unused computational resources in the Internet nodes - users´ machines. In the last years , the peer-to-peer networks (P2P) have gaining a momentum mainly due to its support for scalability and fault tolerance. However, current P2P architectures present some problems such as nodes overhead due to messages routing, a great amount of nodes reconfigurations when the network topology changes, routing traffic inside a specific network even when the traffic is not directed to a machine of this network, and the lack of a proximity relationship among the P2P nodes and the proximity of these nodes in the IP network. Although some architectures use the information about the nodes distance in the IP network, they use methods that require dynamic information. In this work we propose a P2P architecture to fix the problems afore mentioned. It is composed of three parts. The first part consists of a basic P2P architecture, called SGrid, which maintains a relationship of nodes in the P2P network with their position in the IP network. Its assigns adjacent key regions to nodes of a same organization. The second part is a protocol called NATal (Routing and NAT application layer) that extends the basic architecture in order to remove from the nodes the responsibility of routing messages. The third part consists of a special kind of node, called LSP (Lightware Super-Peer), which is responsible for maintaining the P2P routing table. In addition, this work also presents a simulator that validates the architecture and a module of the Natal protocol to be used in Linux routers

Uma arquitetura de software baseada em componentes visualização de informações industriais

Due to the current need of the industry to integrate data of the beginning of production originating from of several sources and of transforming them in useful information for sockets of decisions, a search exists every time larger for systems of visualization of information that come to collaborate with that functionality. On the other hand, a common practice nowadays, due to the high competitiveness of the market, it is the development of industrial systems that possess characteristics of modularity, distribution, flexibility, scalability, adaptation, interoperability, reusability and access through web. Those characteristics provide an extra agility and a larger easiness in adapting to the frequent changes of demand of the market. Based on the arguments exposed above, this work consists of specifying a component-based architecture, with the respective development of a system based on that architecture, for the visualization of industrial data. The system was conceived to be capable to supply on-line information and, optionally, historical information of variables originating from of the beginning of production. In this work it is shown that the component-based architecture developed possesses the necessary requirements for the obtaining of a system robust, reliable and of easy maintenance, being, like this, in agreement with the industrial needs. The use of that architecture allows although components can be added, removed or updated in time of execution, through a manager of components through web, still activating more the adaptation process and updating of the system

Uma arquitetura distribuída de hardware e software para controle de um robô móvel autônomo

In this work, we present a hardware-software architecture for controlling the autonomous mobile robot Kapeck. The hardware of the robot is composed of a set of sensors and actuators organized in a CAN bus. Two embedded computers and eigth microcontroller based boards are used in the system. One of the computers hosts the vision system, due to the significant processing needs of this kind of system. The other computer is used to coordinate and access the CAN bus and to accomplish the other activities of the robot. The microcontroller-based boards are used with the sensors and actuators. The robot has this distributed configuration in order to exhibit a good real-time behavior, where the response time and the temporal predictability of the system is important. We adopted the hybrid deliberative-reactive paradigm in the proposed architecture to conciliate the reactive behavior of the sensors-actuators net and the deliberative activities required to accomplish more complex tasks
