Implementação de software livre na administração pública: um estudo de múltiplos casos no Estado do Rio Grande do Norte

New technologies appear each moment and its use can result in countless benefits for that they directly use and for all the society as well. In this direction, the State also can use the technologies of the information and communication to improve the level of rendering of services to the citizens, to give more quality of life to the society and to optimize the public expense, centering it in the main necessities. For this, it has many research on politics of Electronic Government (e-Gov) and its main effect for the citizen and the society as a whole. This research studies the concept of Electronic Government and wishes to understand the process of implementation of Free Softwares in the agencies of the Direct Administration in the Rio Grande do Norte. Moreover, it deepens the analysis to identify if its implantation results in reduction of cost for the state treasury and intends to identify the Free Software participation in the Administration and the bases of the politics of Electronic Government in this State. Through qualitative interviews with technologies coordinators and managers in 3 State Secretaries it could be raised the ways that come being trod for the Government in order to endow the State with technological capacity. It was perceived that the Rio Grande do Norte still is an immature State in relation to practical of electronic government (e-Gov) and with Free Softwares, where few agencies have factual and viable initiatives in this area. It still lacks of a strategical definition of the paper of Technology and more investments in infrastructure of staff and equipment. One also observed advances as the creation of the normative agency, the CETIC (State Advice of Technology of the Information and Communication), the Managing Plan of Technology that provide a necessary diagnosis with the situation how much Technology in the State and considered diverse goals for the area, the accomplishment of a course of after-graduation for managers of Technology and the training in BrOffice (OppenOffice) for 1120 public servers

Tempo livre de lazer e composição corporal de escolares do meio-oeste catarinense

The aim of this study was to investigate the relationship between free time for leisure and body composition of students in the crucial ninth year. (N = 228) of towns in the Midwest catarinense. We used the Adolescent Behavior Questionnaire of Santa Catarina (COMPAC) to assess lifestyle, considering that Active schoolchildren during the week, accumulated 300 or more minutes of moderate or vigorous physical activity (MVPA). Were used the time to 2 hours or more / day to determine the time of excessive use of TV and computer video game. To analyze body composition were used two criteria: the Body Mass Index (BMI) and sum of skinfolds (EDC). It was observed a proportion of 67.3% of girls and 68.7% of boys assets and more than 98% of students were using excessive TV time, computer and video game. In the classification by EDC, most of the boys showed great or low levels of body composition, while more than half of girls were classified at higher levels. As for BMI, most boys and girls had not overweight. Significant difference in the comparison of total minutes per week of MVPA reported between the groups, the second criterion of EDC and BMI for girls but not for BMI in boys. It is concluded that students with higher accumulation in minutes of MVPA showed better body composition indicators, but no significant difference was found when compared active groups with inactive, according to criteria used.

O princípio constitucional da livre concorrência como instrumento de desenvolvimento socioeconômico

The freedom of concurrence, firstly conceived as a simple market fundament in productive systems that recognized the productive forces freedom of action, appears as a clear instrument of protection and fomentation of the market, recognizing the importance of the simultaneous existence of various economic forces such the proper capitalism reason of constitution. It has, thus, a directly role linked to the fundamental idea that the market and its productive forces needed of a protection against itself, because it exists inside the market situations and circumstances, provoked or not, that could prejudice and even annihilate the its existence and functioning, whilst a complex role of productive forces presents at all economic creation space. It was the primacy of the classic liberalism, the first phase of the capitalism. The Constitutions, in that historic moment, did not proclaim any interference at the economic scenario, simply because it recognized the existence of an economic freedom prepared to justify and guarantee the market forces, with its own rules. Based on the structural changes that occurred at the following historic moments, inside the constitutionally recognized capitalism, it was verified changes in the ambit of treatment of the freedom of concurrence principle that, in a progressive way, passes to present a configuration more concerned with socialist and developing ideas, as long as not only a market guarantee. It emerges a freedom of concurrence which aim is instrumental, in relation to its objectives and constitutional direction as a role, and not anymore stagnant and with isolated treatment, in special at the constitutional systems the present s clear aspects of social interventions and guarantor of fundamental rights more extensive and harmonious. That change is located at a space of state actuation much more ample and juridical important, this time comprehending the necessity of managing the productive scenario aiming to reach a national social and economic development effectively guarantor of fundamental rights for all citizens. Those Constitutions take as point of starting that the social and economic development, and not only anymore the economic growth, is the effective way for concretization of these rights. In that way it needs to be observed and crystallized by political and juridical tools that respect the ideological fundamental spirit of the Constitutional Charters. In that scenario that seeks for solutions of rights accomplishment, in special the social rights, the constitutional principle of freedom of concurrence has been seen as an instrument for reaching bigger values and directives, such as the social justice, which only can be real at a State that can implement a comprehensive and permanent social and economic development. The freedom of concurrence tries to valorize and defend something larger and consonant to the political values expressed in the Constitutional Charters with social character, which is the right to a social and economical sustainable development, guarantor of more clear and compromised collective benefits with social justice. The origin of that constitutional imposition is not only supported by vague orientations of the economic space, but as integrated to it, with basis formed of normative and principles posted and prepared to produce effects at the proper reason of the Constitution

Paradigma constitucional brasileiro da livre concorrência e da defesa do consumidor face às estruturas de poder no mercado

The Federal Constitution of 1988, when taking care of the economical order, denotes special concern in the abuses of the economical power and the disloyal competition. The mark to mediate of all this is, in fact, the defense and the consumer's protection, once this is final addressee of whatever if it puts at the consumption market. The coming of the Law 8.078/90, Code of Protection and Defense of the Consumer, inaugurates a time of effective concern with the homogeneous individual interests originating from of the consumption relationships. In this point, the focus of main to face of the present work lives, in other words, the protection of the right to the individual property, especially manifests in the exercise of the trade freedom that keeps direct relationship with the respective social function the one that is destined. The code of the consumer's defense doesn't just take care of this, but also of the other star of the relationships of the consumption. When affirming in the interruption VI of the art. 4th that the national politics of those relationships, finds ballast in the prohibition and repression efficient of all of the abuses committed in the consumption relationships, keeping inherent relationship-causality in the economical order, sculpted for the article 170 in the Constitution of 1988. In the generic plan, the mark of the present work is to question concerning the limits of the trade freedom and previsible collisions with protection norms and the consumer's defense, as well as factual convergences of those small systems, especially in what he/she refers to the innate interests to the suppliers. In the specific plan, we aspirated to identify the protection device-commands to the actors of the trade relationship, capable to guarantee the free competition in a global economy of market, seeking especially the Well-being, for soon afterwards, in an analytical perspective, to discover the possible applications that it holds the Federal Constitution, in headquarters of economical freedoms. It was observed that the consumer today doesn't need only of laws that their needs, fruit of the vulnerability that it is him/her meditate innate. He/she lacks, yes, of effective mechanisms that prevent lesions that can be them impinged by the suppliers at the time in that you/they are useful to repair the damages when happened, punishing the author of the damage

O dumping ambiental no setor sucroalcooleiro à luz do princípio da livre concorrência

The goal of this study is to investigate about the existence or absence of environmental dumping in the production of fuel ethanol in Brazil, as well as identifying the reasons why the figure of ecological dumping is pernicious to the principles enumerated in constitutional economic order, in particular the principle of free competition. In the twenty-first century environmental issues gained momentum and importance in these terms, which was seen as a mere fallacy given the concern of governments of various countries, after all, environmental protection shows up as the only means of bringing about the maintenance of life at planet. Indeed, it is essential to halt the drastic effects of climate change, and think fast and efficient solutions. Undoubtedly, the contemporary requirements that resulted in the transition to a new economy brings with it the duty of enterprise search for sustainability, and this behavior can not be passive, otherwise it is imperative to work hard and incessant economic agents, even if initially costs are high, this step will ensure a production accountable, transparent and free from accusations of environmental degradation. It is also intended to study the importance of the sector not only as a source of economic growth, but mainly, its contribution to national development, without forgetting that this is devoted in the Constitution of 1988 as one of the objectives of the Federative Republic of Brazil. In fact, the criticism most common perceptions about the production of biofuels, said the interests of the countries producing them in large scale, will eventually generate a exhaustion of soil and a significant increase in food prices. However, the ethanol produced in Brazil is unique in that it is produced from cane sugar, a product is not intended for human or animal, not to mention that the recovery of land just to the rotation with the planting other cultures. It is expected that environmental certifications are useful to demonstrate the quality of ethanol for export and to refute unfounded criticism. Finally, this study will be analyzed further solutions for the plants to develop an economic activity without damaging the environment and in compliance with Brazilian law

Regulação do livre acesso no transporte de gás natural à luz da ordem econômica da Constituição de 1988

In the middle of modern social changes produced by globalization and capitalism, several markets have changed. States have left the direct coordination of these markets (chiefly public utility sector in the form of monopolies), introducing regulation in order to promote competition. These changes have affected natural gas industry by promoting competition as a key factor to the development and the increase of firms in this market. The regulatory reform of natural gas industry ocurred in EUA and Europe Union and it has produced its first results. In Brazilian context, Constitutional Amendment nbr. 09 and Federal Law nbr. 9.478/97 ( Petroleum Law ) opened the natural gas market to a broad range of private economic agents and they finished the monopoly over the industry before managed by Petrobras. The new regulatory framework of Brazilian natural gas industry has designed competition as a central element to the new form of managment of business and contractual relationships of this industry. Among the regulatory instruments, open access regulation in natural gas pipelines is directed to promote competition. The questions arised about its implementation in Brazilian context are studied in the present work, in which it is discussed the constitutional rules and principles are to be applied to the open access regulation within the theme of statal regulation of economy present in constitutional economic order

Livre expressão :para que te quero? o interesse público no ensino do Jornalismo

The main objective of this research was studying the meanings of the freedom of expression and what professors of Journalism think about the way those meanings are used in pedagogical practices. The term freedom of expression is commonly used in journalism even though it is not so studied, consequently we don t have a word to define it. Therefore, we related the term freedom of expression in Journalism teaching to the condition as the object of this study, aiming to establish a connection among the term, the right, free expression and the endurance of the right. The theorical support to understand the dynamic of the meanings of the freedom of expression in the social practice of Journalism teaching was based in the Hegeliana dialetic theorical principles and in the language philosophy more specifically in Bakhtin s perspective from which we can mention the social auditorium, immediate conditions of production and a wider social horizon as the main categories of analysis. This study is a qualitative research with an interacionist perspective anchored in a semi-structured interview as a privileged method of data collecting made with ten professors from Journalism graduation. The analysis reveals that, in the interviewers perspective, there would be a deceiving practice from freedom of expression in the journalism teaching in which emerges either in speeches with handbills spreading the fear and/or under a stimulus form to concealment

A Livre expressão na alfabetização de jovens e adultos: vivências em salas de aula

Cette étude a été faite à partir d une expérience d alphabétisation chez des jeunes et des adultes dans deux groupes du "Projet Réduction de l analphabétisme" realisé par l Université Fédérale du Rio Grande do Norte, le bureau du Ministere de l Éducation et la Préfecture Municipale de Natal-RN. Nous avons choisi la méthode qualitative de recherche, en utilisant l observation de la dynamique en salle de classe, considérant les acteurs sociaux comme étant le sujet actif du processus historique, culturel et politique. Nous avons voulu colaborer dans ce theme en proposant un référenciel théorique et pratique, en visant le dynamisme de la salle de classe, à travers la vision de I alphabétisation centrée sur les utilisations sociales de la lecture et de l écrit; la conception dialogique de Paulo Freire, basée sur la propre culture de l élève et sur sa valorisation en tant que sujet actif de l apprentissage ; la proposition pédagogique de Célestin Freinet dans son aspect de la dynamisation de la salle de classe renforçant le principe de la libre expression, de la colaboration, de l activité et le respect du rytme individuel, pour le succes scolaire. Nous avons rappelé que Célestin Freinet e Paulo Freire ont contribué dans la conscientisation individuelle, sociale, culturelle, politique, de l éleve par le processus scolaire. Nous avons séparé l intérêt et la participation de celles qui alphabétisent et des élêves dans ce processus éducatif. Nous avons constaté tout au long du travail des changements dans la posture de celles qui alphabétisent, surpassant les pratiques centrées dans le formalisme, et le verbalisme fruits de l Éducation traditionnelle. A vançant dans le sens de l Abordage Constructiviste de la connaissance, garantissant un climat de sécurité, de dynamisme et de respect en salle de classe

Aquelas leituras formadoras de culturas (Caicó-RN, século XIX)

La lecture faite du livre Seridó − XIXème siècle (Fazendas & livros), des historiens Medeiros Filhos et Faria, a été ce qui a déclenché l écrit de cette thèse de doctorat. La lecture intensive de ce livre a conduit au corpus documentaire de la recherche (livres scolaires, religieux et laïques, chronique, discours, documents ecclésiastiques, inventaires, testaments, mémoires d'enfance, articles journalistiques, rapports), et aussi au corpus du référentiel théorico-méthodologique de l'histoire culturelle de la lecture, en correspondance avec Roger Chartier et Robert Darnton. Dans la rigueur de l'écriture de la thèse, la recherche relative à la thématique lecture et absorptions culturelles nous a menés à définir comme objet d'étude les pratiques culturelles appropriées pertinemment aux lectures faites, entendues, murmurées, de nombreuses fois répétées et mémorisées, de livres scolaires imprimés, religieux et laïques qui circulaient à Caicó, dans les années mille huit cents. En vue de la lecture intensive et de l'extensive, l'objectif est d analyser, d'une part, des indices d'absorptions ou appropriations culturelles des enseignements de ces pratiques de lecture et, d'autre part, les entrelacements des enseignements relatifs à l'oralité, à la lecture, à l'écrit et à la scolarisation. La thèse défendue est que l'histoire de la lecture à Caicó, au XIXème siècle, est l'histoire de la lecture faite, entendue, murmurée, répétée et, encore, mémorisée, qui, soutenue par des textes de livres scolaires, religieux et laïques, se convertissait dans la production de biens culturels spécifiques, comme des cartes, inventaires, remèdes homéopátiques et faits maison, testaments, prières fortes de cure, vers de cordel, parmi beaucoup d'autres. En commençant avec l'intention d écrire une histoire de la lecture à Caicó, au XIXème siècle, nous comprenons que les pratiques culturelles, spécialement les pratiques des coutumes seridoenses, sont, excessivement, le résultat des appropriations de lectures de textes scolaires, religieux et laïques, stimulatrices d'autres pratiques de lectures intensives et extensives. Si la lecture faite, entendue, répétée, mémorisée et reconnue est liée à des pratiques de coutumes universelles et locales, malgré cela la force de l'oralité aurait été l élément essentiel de la reproduction et de la longévité de cette lecture, ainsi que de son passage du XIXème siècle au XXème et, encore, des vestiges de certaines permanences de ce XXIème siècle. En partie, ce réseau de pratiques culturelles, reproduit par la force de la transmission orale, persiste depuis l époque de nos arrière-arrière-grand-parents

Análise da indução de fluxo de ar por convecção livre em chaminé solar

Experiments were performed to study the effect of surface properties of a vertical channel heated by a source of thermal radiation to induce air flow through convection. Two channels (solar chimney prototype) were built with glass plates, forming a structure of truncated pyramidal geometry. We considered two surface finishes: transparent and opaque. Each stack was mounted on a base of thermal energy absorber with a central opening for passage of air, and subjected to heating by a radiant source comprises a bank of incandescent bulbs and were performed field tests. Thermocouples were fixed on the bases and on the walls of chimneys and then connected to a data acquisition system in computer. The air flow within the chimney, the speed and temperature were measured using a hot wire anemometer. Five experiments were performed for each stack in which convective flows were recorded with values ranging from 17 m³ / h and 22 m³ / h and air flow velocities ranging from 0.38 m / s and 0.56 m / s for the laboratory tests and air velocities between 0.6 m/s and 1.1m/s and convective airflows between 650 m³/h and 1150 m³/h for the field tests. The test data were compared to those obtained by semi-empirical equations, which are valid for air flow induced into channels and simulated data from 1st Thermodynamics equation. It was found that the chimney with transparent walls induced more intense convective flows than the chimney with matte finish. Based on the results obtained can be proposed for the implementation of prototype to exhaust fumes, mists, gases, vapors, mists and dusts in industrial environments, to help promote ventilation and air renewal in built environments and for drying materials, fruits and seeds

Relações entre mídia e lazer:o capitalismo, os meios e a apropriação do tempo livre nas sociedades industrial e pós-industrial

This research aims to understand the relationship between media, capitalism and ownership of free time for leisure practices in industrial societies and postindustrial. Searching is thus a conceptual framework that takes into account the kind of ideology that naturalizes the relationship of leisure with the foundations of contemporary media, and the media only with leisure, forgetting their insertion in the labor and industrial relations in society. We intend to demonstrate that every mode of production, in the capitalist system, entails a mode of reproduction. Methodologically, this is a first approximation, from theoretical concerns already performed, constituting a theoretical research, bibliographic and descriptive character. The results of the text drives us to the conclusion that the work and leisure spheres tend to be less and less differentiated, since both remain as activities of product management with the same intellective protocols, based on information and communication technology, and that accordingly, the media favors an expansion of productive activity even during leisure time

Liberdade e negação da vontade: análise do ser-livre como representação e na angústia

Common understanding about what freedom means has always been more or less related to the power to realize something intended, desired, a capability. Therefore, being free is commonly interpreted under the concept of free-will and the category of possibility to act. Although there are predecessors in History of Philosophy, Schopenhauer refuses the thesis of free will proposing otherwise the denial of willing (to live) as the ultimate possibility for human freedom, if not the only one left. The thesis that would make him famous was deeply misunderstood and so miscarried somewhat due to the way it was many times presented by the means of exotic examples wrapped in a mystical mood besides exaltations to Eastern traditions, which may satisfy anthropological curiosity instead of being capable to satisfy the reader in a philosophical way. It seems to result from Schopenhauer s thought a kind of pessimism against life. Otherwise, typical readings on the Schopenhauerian thesis are found full of inconsistencies once closely regarded, which blame does not belong to the author but to his interpreters. A new reading about the denial of willing as the ultimate possibility for human freedom demands a criticism on the inconsistencies and prejudgments deep grounded. For this, we firstly clarify the ways of understanding the willing nothing , which cannot be reduced to the mere refusal or conformism, being instead positively understood as a special manner of willing: the admission of oneself for the sake of one is. A few more than a century later The world as will and representation came to light, Heidegger proposes in his fundamental ontology that the proper being-free concerns to originary decision by which, in anguish of being suspended in nothingness, Dasein renders itself singular as the being who is in-a-world and to-death, concluding that the ultimate possibility of freedom is being-free-to-death. Developing the hypothesis that freedom, properly understood, concerns to nothingness as to indeterminate possibilities, we seek for a dialogue between Schopenhauer s thought and existential philosophy aiming to reconstitute and overcome Metaphysics tradition turning the question about freedom into a matter of Ontology. From the factual existence perspective, as we must show, every human activity (or inactivity) is ordinarily mediated by representations, in which me and world appear as distinct entities. So, each one among determininate individuals finds itself connected to the things in the world by interest, which proper concept must be sufficiently explored. Starting from this point, we may proceed to detailed analysis of usual representations of freedom aiming their destruction by Ontology and then reaching existential thesis according to Kierkegaard and Heidegger. Turning back to the analysis of Schopenhauer s work, we conclude existential understanding of freedom as will-to-be can also be found in Schopenhauer. In this way, denial of willing means ultimate freedom once the Will turns back to its own essence by suppressing the world as representation, which means the originary absolute indetermination of the extreme possibility to-be

Falhas e complicações com o uso de prótese parcial removível inferior de extremidade livre bilateral

Aim: To determine the frequency and type of complications related to removable partial denture (RPD) less, Kennedy Class I, over time . Materials and Methods: This observational study consisted of a sample of 65 users PPR lower arches in Kennedy Class I and dentures, rehabilitated in the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). Patients were followed through periodic controls during periods of 60 days, 6 months and 1 year from installation. After the first year of control had other returns annually. The occurrence of complications or prosthetic failure was observed and recorded in a specific clinical record over 39 months. The patterns of failures observed were classified in the following situations: occurrence of traumatic ulcers after 2 months of installation, lack of retention, fracture or caries in the rest, fracture or dislocation of the artificial teeth, the larger connector fracture, fracture clip fracture support, poor support (need to reline the denture) and prosthesis fracture. Results: The incidence of complications was low frequency, being higher in the second year of use of the prosthesis. Among the complications that occurred more is the loss of retention (31.57%). Failures more severe and difficult to solve as the fracture elements of the metal structure of the PPR had low occurrence and were represented by only one case of the larger connector (5.3%) fractures. Conclusion: Removable partial dentures mandibular free end opposing of the conventional dentures have a low complication rate after 39 months of use when subjected to periodic controls
