Metodologia BIM: uma nova abordagem, uma nova esperança

A metodologia BIM (Building Information Modeling), tem vindo a ganhar grande importância na indústria da AEC (Arquitetura, Engenharia e Construção). Este conceito introduz alterações muito significativas na forma como atualmente se aborda a conceção, construção e manutenção de edifícios. Apesar da emergente utilização, não existem neste momento normas de boas práticas para a sua implementação em Portugal. O BIM tem como princípios a integração das fases do processo construtivo, a integração e trabalho colaborativo de todas as especialidades envolvidas na fase de projeto, sendo apoiada por aplicações de visualização tridimensional. O grande potencial do conceito BIM está também na normalização da informação, sendo suportada entre outros aspetos na normalização da forma como se devem modelar os objetos. Assente nesta base são várias as potencialidades que daqui decorrem. No âmbito desta dissertação pretende-se abordar e aplicar a metodologia BIM ao projeto de estruturas e de especialidades que foi previamente elaborado segundo a metodologia tradicional (CAD 2D). Pretende-se, clarificar a metodologia BIM e avaliar algumas das ferramentas computacionais disponíveis no mercado. O caso de estudo da presente dissertação, permitiu identificar algumas dificuldades e falhas existentes nos projetos a 2D, o que não acontece no caso da metodologia BIM.

Percepções de maturidade em gerenciamento de projetos à luz da nova gestão pública: uma investigação com gestores das secretarias estaduais do Rio Grande do Norte

This study aimed to measure the perception of maturity project management of state boards of Rio Grande do Norte by the perception of its managers. Argues that project management has been highlighted as a critical factor for the success of any organization, because the projects are directly related to the set of activities that result in organizational innovation as products, services and processes and the improvement of project management is directly aligned with the main pillars of the New Public Management. Methodologically, this is a quantitative research of a descriptive nature in which 161 forms were applied with coordinators and subcoordinators of state departments of Rio Grande do Norte, culminating in a sampling error of less than 6% to 95% confidence according to the procedures finite sampling. The process of tabulation and analysis was done using the package Statistical Package for Social Sciences - SPSS 18.0 and worked with techniques such as mean, standard deviation, frequency distributions, cluster analysis and factor analysis. The results indicate that the levels of maturity in project management in state departments of Rio Grande do Norte is below the national average and that behavioral skills are the main problem for improving management in these departments. It was possible to detect the existence of two groups of different perceptions about the management of projects, indicating, according to the managers, there are islands of excellence in project management in some sectors of the state departments. It was also observed that there are eight factors that affect maturity in project management: Planning and Control , Development of Management Skills , Project Management Environment , Acceptance of the Subject Project Management , Stimulus to Performance , Project Evaluation and Learning , Project Management Office and Visibility of Project Managers . It concludes that the project management in state departments of Rio Grande do Norte has no satisfactory levels of maturity in project management, affecting the levels of efficiency and effectiveness of the state apparatus, which shows that some of the assumptions that guide the New Public Management are not getting the levels of excellence nailed by this management model

Treinamento e desenvolvimento de pessoas e a nova gestão pública : o caso do projeto Formação de tecnólogos em gestão pública do governo do Rio Grande do Norte

This thesis aims to identify how civil servants perceive changes made inthe carrying out of their work after their taking part in the Course forTechnicians in Public Management of the Government of Rio Grande do NorteState. As for the methodological procedures, an exploratory-descriptivequantitative research has been carried out through structured questionnaires appliedto 118 civil servants from the first groups of the Course for Technicians, thusshowing a margin of error of 4.18% to 95% of confidence, according to theprocedures of finite sampling. The table processing and analysis rested uponthe Statistical Package for the Social Sciences SPSS and was carried outthrough univariate, bivariate and multivariate techniques with emphasis on thetechnique called Factor Analysis. It was possible to identify that the level ofsatisfaction of the students was high and there was a clear perception by themthat the course assisted to changes in their work. Through Factor Analysis itwas verified that the factors that may be related to changes in the work of thecivil servants are "Contribution to Society", "Efficiency andEfficacy in the Work Environment", "Applicability of Contents"and "Capacitating for Leadership". The conclusion of the studyindicates that the factors obtained are directly related to the basis of thenew public management by means of guidance toward efficiency and efficacy in aperspective of leadership, the contents of the course being thus made into newattitudes toward work which end up yielding better results for society

A verdade (des)construída: a inserção da homossexualidade na comunidade cristã Nova Esperança, em Natal

The religious plurality has been increasingly intense in Brazil, while it has served as an object of study in various fields of knowledge. In this context, this paper aims to point out the general heterogeneity among experienced growth of Protestant and evangelical denominations, especially those who claim to be inclusive by attending to human diversity, seeking to understand the relationship between religion and homosexuality. Specific objectives aim to understand the functioning and speeches produced by Comunidade Cristã Nova Esperança in Natal. The theoretical framework was seated in the works of Bento (2008), Lima (2009), Goffman (2001), Natividade (2008), Musskopf (2008), Helminiak (1998), Foucault (1997), among others. We tried to discuss the trajectory and how is the process of organization of the Comunidade Cristã Nova Esperança in Natal, the social advances that have reached homosexuals in our country, how this institution has contributed to the shift in paradigm in Christianity in respect to matters pertaining to religion and homosexuality, and the meaning of being a homosexual christian from the viewpoint perceived by social subjects living this experience

De gata borralheira a Cinderela :nova espacialidade decorrente do desenvolvimento turístico, diferenciada pelo estilo de vida em Ponta Negra, Natal, RN

The transformations economical, social and politics in you finish them decades of the century XX brought changes that didn't just limit to the production system. The flexible accumulation took many workers lost her/it their workstations and they look for her/it new survival forms, migrating for administrative activities, of services rendered and for the tourist activity of small and medium load. The State has been investing in the implantation of plans of tourist development in order to create favorable conditions for the reproduction of the tourist activity in Brazil, mainly in the Northeast. A space when it starts to present a predominant economical activity suffers a restructuring in their social and economical relationships. The restructuring of these relationships takes to the construction of a new espacialidade. In the city of Christmas, in Rio Grande do Norte, the neighborhood of Black Tip is the most representative of the public investments for the tourist development. After intense process of tourist urbanization, Black Tip passed interfering in the global context consolidating as the tourist locus in the city. The tourist urbanization of the neighborhood took to the transformation of the space in merchandise that is sold and consumed as such. The recreation of fragments of other cultures brought by social actors, resulting from migratory processes stimulated by the tourist development, it has been presenting ruled social relationships in the informational technology, consumption of global goods and in the fragmentation of the urban space characterized by the internationalization and cosmopolitização. That process has been masking the inequalities partners and cultural as well as the territorial appropriation for an economical elite. The spaces are being appropriate for investors of the tourist section, private investors, agents and real estate producers, where the inequality is not just economical, but also cultural. The local population, mainly of the urban fraction of the Town of Black Tip, it doesn't participate of the productive process in function of the little or any professional qualification and he/she doesn't also have access to the consumption process. To the native ones it remains the fight for the preservation of his/her cultural identity and for the survival

Análise dos efeitos da legislação urbanística na formação e crescimento do Bairro de Lagoa Nova: planos diretores de 1974, 1984 e 1994

Nitretação iônica sem efeito de borda :desenvolvimento e avaliação de uma nova técnica

The ionic nitriding process presents some limitations related with the control of the thickness of the layer and its uniformity. Those limitations that happen during the process, are produced due to edge effects, damage caused by arcing arc and hollow cathode, mainly in pieces with complex geometry and under pressures in excess of 1 mbar. A new technique, denominated ASPN (active screen shapes nitriding) it has been used as alternative, for offering many advantages with respect to dc plasma conventional. The developed system presents a configuration in that the samples treated are surrounded by a large metal screen at high voltage cathodic potencials, (varying between 0 and 1200V) and currents up to 1 A. The sample is placed in floting potential or polarized at relatively lower bias voltages by an auxiliary source. As the plasma is not formed directly in the sample surface but in the metal screen, the mentioned effects are eliminated. This mechanism allows investigate ion of the transfer of nitrogen to the substrate. Optical and electronic microscopy are used to exam morphology and structure at the layer. X-ray difration for phase identification and microhardness to evaluate the efficiency of this process with respect to dc conventional nitriding

Nova técnica para obtenção de fraturas com altíssima condutividade em poços de petróleo

Increase hydrocarbons production is the main goal of the oilwell industry worldwide. Hydraulic fracturing is often applied to achieve this goal due to a combination of attractive aspects including easiness and low operational costs associated with fast and highly economical response. Conventional fracturing usually involves high-flowing high-pressure pumping of a viscous fluid responsible for opening the fracture in the hydrocarbon producing rock. The thickness of the fracture should be enough to assure the penetration of the particles of a solid proppant into the rock. The proppant is driven into the target formation by a carrier fluid. After pumping, all fluids are filtered through the faces of the fracture and penetrate the rock. The proppant remains in the fracture holding it open and assuring high hydraulic conductivity. The present study proposes a different approach for hydraulic fracturing. Fractures with infinity conductivity are formed and used to further improve the production of highly permeable formations as well as to produce long fractures in naturally fractured formations. Naturally open fractures with infinite conductivity are usually encountered. They can be observed in rock outcrops and core plugs, or noticed by the total loss of circulation during drilling (even with low density fluids), image profiles, pumping tests (Mini-Frac and Mini Fall Off), and injection tests below fracturing pressure, whose flow is higher than expected for radial Darcian ones. Naturally occurring fractures are kept open by randomly shaped and placed supporting points, able to hold the faces of the fracture separate even under typical closing pressures. The approach presented herein generates infinite conductivity canal held open by artificially created parallel supporting areas positioned both horizontally and vertically. The size of these areas is designed to hold the permeable zones open supported by the impermeable areas. The England & Green equation was used to theoretically prove that the fracture can be held open by such artificially created set of horizontal parallel supporting areas. To assess the benefits of fractures characterized by infinite conductivity, an overall comparison with finite conductivity fractures was carried out using a series of parameters including fracture pressure loss and dimensionless conductivity as a function of flow production, FOI folds of increase, flow production and cumulative production as a function of time, and finally plots of net present value and productivity index

Prática desportiva e qualidade de vida de crianças do bairro de nova descoberta Natal / RN

Objective: This study aimed to investigate the contribution of sports activities for children participating in social programs. Method: It s dealt with in a survey of a descriptive nature. The sample was composed of 51 participants from the Project Nova Descoberta, ranging in ages from 8 to 17, males (n=29) and females (n=22). A semi-directed interview was applied with 10 items over a period of 2 consecutive years (2007-2008) with children and adolescents, besides obtaining documental data in the schools that have an agreement with the Project. Results: The performance of the participants in the groups that joined and did not join in terms of schoolwork production in the year 2007 did not present statistical differences (p<0,05). A significant difference (p<0,05) was observed in the discipline of Portuguese when compared between the groups, with a higher average for the students who joined in 2008. Discussion: In the face of the context found in social sports projects, emerges a series of indicators that contribute for a reliable evaluation. The manifestation of other characteristics in the environment could be interfering in the participation and involvement in physical activity and consequently in the health and quality of life situation of the children and adolescents. Conclusion: It was confirmed that the school work performance indicators can be taken together with other indicators, such as a development of various abilities, participation in other activities, motivation for the activities, behavior and attitudes at home and at school, for evaluation of social projects

Do lixo à solidariedade : avanços e perspectivas na busca de uma nova realidade

The dissertating study about the solidarity economy has the objective to analyze the four unions responsible for the selective municipal garbage collection in Natal. It aims at verifying the consolidation of these unions as solidarity economic undertakings, revealing which progresses they have made, as well as the social and economic insertion of the garbage collectors and their process of conquering citizenship. The referred four unions had been founded and are constituted, in their majority, by collectors coming from the Cidade Nova lixão (big garbage). As it was closed in August 2004, they decided to make a union in order to collecting garbage. As what concerns the methodic and theoretic proceedings, our research has been developed with a critical perspective and a qualitative approach without discarding and quantitative one. The central analytical categories of this paper are: association, work, social exclusion and citizenship. Our research has had three articulated axis which aim was to apprehend the subject, disclosing it. The exposition of the investigative results is subdivided in four chapters. The first one approaches the main aspects of the crisis of the capital and its reflexes in the world of work. Here we deal with the question the structural unemployment coming as a result of the present economic model, the mains changes verified in the Brazilian work market, as well as levels of unemployment affecting the work market in Natal s metropolitan region. The second chapter treats of the origin, concept and revival in Brazil concerning the tradition of thought and cooperative economic organization, which has recovered the central elements of the associative thought and is nowadays studied in Latin America under the name of solidarity economy. The third chapter deals with embodiment of the collectors unions, its history, appearing and development of each union. The fourth chapter presents the relative dimensions of the analysis categories supported in the reports of institutional actors as well as the perception collectors have about the recyclable stuffs, the way they face the daily life and so on, what brings about the contradictions present in their reality. The final comments sum up the main trends and particularities of the unions researched under the light of the solidarity economy and disclose the real perspectives of social and economic insertion of these collectors and the process they follow to conquest social recognition

Direção espiritual na TV canção nova: análise do discurso do Padre Fábio de Melo

The aim of the research is to analyze Direção Espiritual a TV program produced by Catholic Church and presented by Canção Nova Channel. The program is presented by Father Fábio de Melo, a catholic priest that also is a famous religious singer and writer. The analyses included not only some TV programs, but also interviews with some of the viewers and Fabio de Melo himself. The results points out the emergence in Brazil of a new religious speech from Catholic Church founded in comprehension path, dissociated from punishment and guilty. This religious speech is more like a self help speech rather than a tradicional religious discourse itself, very similar to psychotherapeutic speech. The TV program presented by Fabio de Melo is guided in tiny line of sacre and profane which announces contradictions but also a new blend of religious approach in contemporary days

Plano de Desenvolvimento da Escola (PDE): o processo de implantação de uma nova proposta de descentralização em duas escolas da rede municipal de ensino de Natal de 1999 a 2002

The 1988 Constitution was the legal marc to define changes in Brazilian State with major importance to the layout of public politician. In that moment of redefinitions e openness to new ways the redemocratization, participation and decentralization of public school had as their starter the elementary school. This work focus on the manage of FUNDESCOLA, particularly one of its politics called PDE (Educational Development Plan) wich purpose is guarantee a better quality in teaching and spread out democracy throughout its methodology. It was chosen two public schools: Professor Ulisses de Góis and Antonio Campos. The theoretical and methodological orientation is based on the theory of participative democracy developed by authors such as Putnam and Pateman. They says that a cultural background precedes individual participation in society. The collected data (educational legislation, surveys with all sectors of schools and technicians of Natal educational secretary, and relevant documents of de institutions) showed that PDE. Implementation had opposite runnings in the schools studied. In one, as a consequence of bad preparations of its teachers to absorve its methodology, PDE failed. In another way, PDE achieved its goals, especially helping the structure of action plans of the school and the administrative organization making possible several pedagogic activities planned. The work concludes that the main factor the failure or success of PDE relies on the organizational (both political and pedagogical) structure of each school. This discovery implies three important guidelines when comes to formulation of public politicians: a) Constitution of school; b) the local actors who manages the actions; c) the colletive interest in taking part of decisions

A ética econômica das classes trabalhadoras: a gramática social do comportamento econômico da nova pequena burguesia comercial de Natal/RN

Rogram relying on sociological interface between Economic Sociology, Sociology of Moral Theory of Socialization and Social Stratification, this dissertation research makes use of theoretical contributions Luic Boltanski, Charles Taylor, Axel Honneth, Pierre Bourdieu and Bernard Lahire to problematize the generally about the physical and symbolic production and social reproduction of the type of "economic ethics" predominant in the new petite bourgeoisie Brazilian. In other words, the goal is to explain and analyze the objective conditions (economic needs and moral grammar) and intersubjective (modes of socialization and social networks) and update the social genesis and contextual transcontextual beliefs, biases, inclinations and cultural regularities observed the economic behavior of individual profiles for the fractions of the urban petty bourgeoisie and commercial upward Natal / RN. With regard to methodological strategies adopted in data collection will be conducted qualitative interviews (semistructured) and ethnographic notes. In turn, the analytical treatment of the collected empirical content is based on the approach dispositionalist (Pierre Bourdieu, Loïc Wacquant and Bernard Lahire) that emphasizes the study of the past embedded agents and the different contexts of incorporation / activation / inhibition of "provisions" individual cultural

Entre a Anta e a Cruz: história e memória da cidade de Nova Cruz - RN

Dans ce travail, nous étudions la construction narrative du passé de la ville de Nova Cruz, dans l´agreste potiguar. Les récits soulignent l´existence d´un corpus narratif homogène qui fait référence à l´occupation du lieu et à l´évangelisation de ses habitants. Ainsi, les images des saints et des missionaires civilisateurs de l´espace qui domestiquent les manifestations d´un esprit autochtone sauvage, habitants du milieu naturel, sont recurrentes dans la description des personnages du passé. Observant la continuité sémantique des différentes versions de l´histoire de la ville, nous nous proposons d´analyser d´une manière conjointe les textes de l´historiographie locale et les témoignages oraux collectés. Comme il a été possible de le constater, les chemins de l´écrit et de l´oral se croisent en plusieurs occasions, obéissant à des logiques locales de représentations du passé. Ainsi, notre étude porte sur des champs communs à l´Anthropologie, à l´Histoire e à la Littérature. Les reconstructions narratives du passé local sont aussi activées par des faits plus récents, des "marques de la mémoire" comme le marché, le train, la croix et le réservoir, symboles d´une époque d´abondance qui suit l´action civilisatrice des personnages ancestraux

Utilização intracoágulo de espuma fibrinolítica - preparação, caracterização e atividade in vitro de uma espuma de estreptoquinase e proposta de uma nova abordagem terapêutica

Foam was developed as a novel vehicle for streptokinase with the purpose of increasing the contact time and area between the fibrinolytic and the target thrombus, which would lead to a greater therapeutic efficacy at lower doses, decreasing the drug s potential to cause bleeding. Fibrinolytic foams were prepared using CO2 and human albumin (at different v:v ratios), as the gas and liquid phases, respectively, and streptokinase at a low total dose (100,000 IU) was used as fibrinolytic agent conveyed in 1 mL of foam and in isotonic saline solution. The foams were characterized as foam stability and apparent viscosity. The thrombolytic effect of the streptokinase foam was determined in vitro as thrombus lysis and the results were compared to those of a fibrinolytic solution (prepared using the same dose of streptokinase) and foam without the fibrinolytic. In vitro tests were conducted using fresh clots were weighed and placed in test tubes kept at 37 ° C. All the samples were injected intrathrombus using a multiperforated catheter. The results showed that both foam stability and apparent viscosity increased with the increase in the CO2:albumin solution ratio and therefore, the ratio of 3:1 was used for the incorporation of streptokinase. The results of thrombus lysis showed that the streptokinase foam presented the highest thrombolytic activity (44.78 ± 9.97%) when compared to those of the streptokinase solution (32.07 ± 3.41%) and the foam without the drug (19.2 ± 7.19%). We conclude that fibrinolytic foam showed statistically significant results regarding the enhancement of the lytic activity of streptokinase compared to the effect of the prepared saline solution, thus it can be a promising alternative in the treatment of thrombosis. However, in vivo studies are needed in order to corroborate the results obtained in vitro
