Expansão imobiliária na cidade de João Pessoa, no período de 2009-2013: um caso de formação de bolha?

The housing boom recorded in recent years in the city of João Pessoa contributed decisively to the increase in housing supply across the all territory. This advance, however, was accompanied by a significant increase in property prices, which in itself generates enormous expectations on the support of the same medium and long term. From this apparent frame heating the housing market of this Capital. This study empirically examined whether this enhancement configured a typical process of bubble formation between the years 2009 and 2013 in this part of Capital. The empirical price dynamics of the housing market , was based on the indicators of price, rent and cost developed by Bezerra et al. (2013). The results of these local indicators increase the degree of confidence in the hypothesis seen, whatever, that the movement of prices in the main districts of the city of João Pessoa is a real estate bubble

Avaliação da conformidade dos blocos cerâmicos produzidos em algumas cerâmicas no Rio Grande do Norte

The final quality of the works accomplished by the building construction industry depends directly on the quality of the materials supplied and used during all their phases of execution. The federal government participation and several state programs have established conditions to stimulate and require the increment of the quality level in the building construction industry´s product chain. These programs aim at the product conformity to the technical standards. Within this context, the evaluation program of the ceramic product conformity in Rio Grande do Norte state is assessing the conformity degree to Brazilian Technical Standards of ceramic bricks and tiles made in the ceramic production area in the state. In this work, is determine the degree of conformity of the sealing ceramic bricks made by some companies in different areas of the state, such as Assú, São Gonçalo do Amarante, Apodi, Parelhas, São José do Mipibu e Macaíba. Using the technical standards as a point of reference, we attempted to reproduce in the laboratory the experimental procedures to the analysis execution, according to the specifications. It was possible to determine that none of the evaluated samples are in strict conformity with the current technical standards, what reflects the real situation of the products available on the market.

Análise do processo de avaliação de desempenho ambiental face às diretrizes da ISO 14031: um estudo de caso

The present dissertation aims to analyze the evaluation process of environmental performance inside an organization from the building construction section of civil construction based on the NBR ISO 14031 guidelines, which provide orientation regarding the implementation of this project towards the internal organizational management. The theoretical research has addressed concepts and historical development of environmental management inside organizations, from the emergence of the first models to the strengthening of environmental management through the standardization of the Environmental Management System caused by the publication of ISO 14001. It has also addressed the evaluation of environmental performance, the NBR ISO 14031 (concepts, types of indicators of evaluation of environmental performance, the elaboration process of such indicators, as well as its use and evaluation by the high administration). The research has an applied character, with exploratory and descriptive goals, and a qualitative approach based on case study. The data collection will be made through questionnaires, interviews, and documental analysis. Through the present research project, one expects to learn the elements taken into consideration by the organization for the elaboration and selection of indicators; to identify which interested parties contribute in the aforementioned process; to discover which sources are taken into consideration by the organization while establishing its environmental performance goals; to learn how the different kinds of environmental indicators are handled by organizations on daily basis, considering the existence of interferences on the decision making process, whether or not the interested parties are integrated, and if there is an periodical evaluation of environmental performance and how it is handled. One also expects to identify the opportunities for improvement regarding the organization that is object of study.

Revestimento decorativo monocamada pigmentado, com resíduo de vidro temperado, para aplicação em fachadas

Although efficient from a technical point of view, mortar layers that make up the traditional masonry coating (slurry mortar, plaster and plaster) have to be in contradiction with the new construction technologies and more efficient methods of consumption and work rationalization. From an environmental point of view, the recovery of waste into new composites for the building has been a growing strand of studies in the scientific community, may prove to be a cost-effective solution in some cases. Thus, this research proposes the development of a mortar Decorative Coating Monolayer (RDM), for use in facades, produced on site, incorporating tempered glass waste (RVT) in the cement matrix, as a partial substitute for aggregate. Therefore, we adopted the binder respect / aggregate of 1: 6 (by volume), consistency index 250mm ± 20, sand substitution levels of glass waste 20%, 50% and 80% and relative water / cement varied in many traits. Two additives were used, a polymer, styrene-butadiene-based, and other chemical, besides mineral and silica fume inorganic pigment in colors red, yellow and blue. Mechanical tests were carried out on fresh pasta and hardened, as well as for the applied coating on masonry, so as to demonstrate the feasibility of the material. In addition, it verified the adequacy of the RDM built environment by means of thermal tests. The results demonstrated the feasibility of the proposed RDM with significantly higher values when compared to norms, especially the dash-added replacement content of 20% and addition of pigment in red. Therefore, the study shows the scientific community as an incentive to the use of technological innovations in construction, increasing the range of alternatives available for housing production, with the proposition of a material that achieves the desired functionality and obtain environmental gain, and may be adopted on construction sites as an alternative industrialized mortars.

Esquina edifício: uma proposta arquitetônica para um edifício misto

Natal, como outras cidades metropolitanas brasileiras, sofreu nas últimas décadas uma forte transformação impulsionada pelo mercado imobiliário e pela indústria da construção civil. A produção de apartamentos em condomínios fechados vem crescendo e tornando cada vez mais comum, no cenário urbano, a presença de torres residenciais (com extensos muros e grades, fachadas cegas e guaritas) que favorecem o “desurbanismo”. Por outro lado, este tipo de empreendimento, o edifício multifamiliar, apresenta plantas baixas padronizadas as quais frequentemente são incoerentes com a diversidade de perfis dos usuários. A consequência disso são reformas e adequações nos apartamentos após a entrega da obra. Diante deste contexto, elaborei uma proposta arquitetônica, que é apresentada nesta dissertação, como alternativa a essa modalidade de produção que está se tornando dominante no Brasil e em outros países. Dois conceitos nortearam esta proposta: a) o conceito de urbanidade cujo objetivo no projeto arquitetônico é favorecer a percepção do outro (por copresença e/ou cociência) através da permeabilidade, acessos e passagens entre o edifício e o entorno. A maneira como os cheios (barreiras) se estruturam com os vazios foi trabalhada de modo que definissem propriedades espaciais cuja intenção é facilitar o encontro e a diversidade entre moradores e entre estes e os de fora, no entanto sem desconsiderar o problema da violência urbana e, consequentemente a importância da promoção de segurança para os usuários. b) o conceito de flexibilidade a fim de possibilitar ao consumidor final o desmembramento da unidade habitacional em duas e, em especial, a participação e ou escolha na concepção do arranjo interno e da definição dos acabamentos do seu apartamento. Tudo isto durante a construção do empreendimento e ao longo da sua vida útil, favorecendo assim o potencial de diversidade (grupos sociais), adaptabilidade a fases distintas da vida e durabilidade do edifício.

Análise das LER/DORT notificadas no Rio Grande do Norte de 2010 a 2014

The increasing prevalence of Repetitive Strain Injury / Work-Related Musculoskeletal Disorders (RSI / MSDs) has been explained by changes in the work that has been characterized by setting goals and productivity. This fact does not take into account the psycho-physiological characteristics of workers who become ill as a result of professional activities engaged in and also the adverse conditions in which his work was done. This study aimed to analyze the RSI / MSDs reported in the state of Rio Grande do Norte, Brazil, 2010-2014 compared to the profile of the population, epidemiological aspects and features of these diseases. It is a descriptive epidemiological cross-sectional study using secondary data obtained in the Notifiable Diseases Information System (SINAN) in May 2015 was used as the area covered by the Rio Grande do Norte. Data were collected regarding the grievances of work-related RSI / MSDs, assigned by the Worker's Health Reference Center (CEREST) of the State Health Department. Data were processed with the help of Microsoft Excel® 2013 and presented in tables in absolute frequency (n) and relative frequency (%). The results showed a total of 403 notifications of RSI / MSDs, where the vast majority 72% (290) was recorded in Natal. Regarding the profile of notified employees, 88.59% (357) have aged between 25 and 54 years, 62.78% (253) were female, and in relation to education, 31.51% (127) had high school complete. The most affected occupations were seamstresses (the clothing industry) with 24.97% (97), followed by masons, construction with 3.23% (13) and cashiers with 2.99% (12). About the work situation, 75.93% (306) had a formal contract, however, were sent to Communications Occupational accidents (CAT) only 67% (270) of the cases. Regarding the signs and symptoms, pain and limitation of movement were the most mentioned respectively with 98.01% (395) and 95.04% (383) of notifications. Notifications, 94.29% (380) showed exposure to repetitive movements in their workplace. The most frequent specific diagnoses were synovitis and tenosynovitis (CID F 65), with 30.02% (121) of notifications, followed by back pain (CID F 54) to 19.35% (78) and shoulder injuries (ICD M 75) with 15.88% (64). They were away from work 81.64% (329) of workers reported with RSI / MSDs. Evolution more prevalent among cases was temporary disability with 75.68% (305). It was concluded that the SINAN is a database of potential to characterize the profile of RSI / MSDs, requiring, however, an improvement in the coverage of records and data quality. In addition, this study reflects the need to implement protection strategies to workers by companies, signaling promotion, prevention and rehabilitation aimed at reducing these injuries and the improvement of occupational health indicators in Rio Grande do Norte.

Magnitude da morbidade relacionada ao trabalho no Rio Grande do Norte

Diseases and disorders related to work sets up an important public health problem in Brazil and worldwide. However, the reality of these diseases still constitutes a gap with regard to its characterization and epidemiological situation, especially in Brazil. In this context, this study aims to analyze the magnitude of morbidity related to work from the injuries and illnesses reported by Health the Diseases Notifiable of Health of the State Public River Health Department worker Reference Center Information System services Grande do Norte from 2007 to 2014. It is ecological study, quantitative cross-sectional study in which the analysis unit of the municipalities of Rio Grande do Norte. Data were collected from the state base of Diseases Notifiable Information System Centre of the Secretariat of State Workers' Health Reference Public Health of Rio Grande do Norte, between March and June 2015, after the approval of the Committee of Ethics in Research of the Federal University of Rio Grande do Norte, Opinion 014/2014. The population was represented by the universe of cases of diseases and disorders related to work that were reported and shut down the system from 2007 to 2014. Data were analyzed using descriptive and inferential statistics, presented in tables, graphs, charts and figures. For this, we used the Microsoft Excel 2007 and SPSS version 20.0. To check the significance level we opted for the application of the chi-square or Fisher tests. We adopted the significance level of p <0.05. Of the 10,161 cases of diseases related to the reported work, the biological work accidents had the highest percentage (52.84%) followed by serious occupational accidents (37.49%). For diseases, the highlights were musculoskeletal (4.82%), mental disorders (2.19%) and exogenous intoxication (1.97%). Among men, there was a predominance of major accidents (91.80%), mental disorders (70.00%) and exogenous poisoning (52.84%). Women were most affected by biological accidents (77.50%) and musculoskeletal diseases (64.10%). Among workers who have suffered injuries predominated mulatto (%), mean age of 35.86 years, low education (%) and workers in the formal sector (%). Among the accidents, biological (n = 5,369) accounted for 52.84% of cases occurred predominantly among nursing professionals (48.31%). The percutaneous exposure was the most frequent (73.05%) and the occurrence of circumstances was improper disposal of sharps (45.28%), the needle the most common agent (66.62%) and the organic material was blood (72.99%). Most injured workers were vaccinated against hepatitis B (68.13%), but no information as to the assessment of the vaccine response. In the course of the disease predominated ignored the situation with loss of monitoring of clinical follow-up (55.62%). There was also an increase in the notification of serious industrial accidents predominantly male (91.80%) workers aged 25-44 years (54.3%) and typical accidents (76.3%). The temporary disability was the most common outcome (55.53%) and hand the most affected part (33.00%); the mining and construction industry had the highest number of cases (25.1%) in registered employee (34.2%). The findings of this study show a positive result in relation to increased mandatory reporting of injuries and illnesses related to work together to health services that meet victimized workers, towards the occurrence of knowledge of these accidents for decision making in public plans and policies of health. However, the information system still needs improvement in both the coverage and the quality of the data to demonstrate with greater reliability the magnitude of events to support the planning of workers' health into shares in the state.

Metodologias de determinação de alturas de onda para dimensionamento de obras marítimas

O clima marítimo ao longo da costa da Região Autónoma da Madeira (RAM) apresenta algumas diferenças, sendo para isso fundamental efetuar uma análise das características oceanográficas e geotécnicas do Arquipélago da Madeira. A referida análise tem como pressuposto retratar, o mais fiável possível, as diferenças, incidindo especialmente nos Portos do Funchal, Caniçal, Porto Moniz e Porto Santo. A caracterização e simulação da propagação da agitação marítima, aplicada a estruturas portuárias da RAM, representam o cerne desta dissertação, sendo os seus objetivos primordiais: a definição da onda de projeto de uma obra marítima; a descrição da metodologia de determinação de estimativas de longo prazo; a análise comparativa; a definição de metodologias de cálculo e a aplicação a registos da costa da RAM. Numa primeira fase procedeu-se à recolha de informação bibliográfica e de todos os registos informáticos disponibilizados pelas identidades responsáveis, nomeadamente a Administração dos Portos da Região Autónoma da Madeira (APRAM). Posteriormente efetuou-se um registo fotográfico das estruturas portuárias de modo a poder enquadra-las geograficamente na região. Com recurso aos dados fornecidos pela APRAM e a folhas de cálculo desenvolvidas no programa Microsoft Excel foi possível efetuar uma análise das alturas de onda significativa, do período de pico e da direção de ocorrência, por forma a poder caracterizar a agitação marítima que ocorre em cada um dos locais alvo deste estudo, sendo esta complementada pela análise das variáveis oceanográficas através do programa Carol. O passo seguinte incidiu sobre a análise da propagação da agitação marítima em cada um dos locais analisados, com recurso ao programa Mopla e à caracterização supracitada, por forma a conseguir definir a altura de onda que ocorre na estrutura portuária em causa. Como tarefa final são expostas as principais conclusões, algumas considerações finais e alguns objetivos que deveriam ser alcançados num futuro próximo.

Avaliação do ciclo de vida de um pavimento flutuante de cortiça

A consciencialização ambiental vem assumindo um papel preponderante na construção civil. Nesse sentido, o desenvolvimento de materiais sustentáveis e ecológicos é essencial para a satisfação de fabricantes e consumidores, respeitando diversos requisitos: níveis reduzidos de poluição e toxicidade, durabilidade dos materiais, possibilidade de reutilização e/ou reciclagem, a proveniência das matérias-primas e a possibilidade de contaminação do ar no interior dos edifícios. As declarações ambientais de produto (DAP) permitem informar o consumidor do desempenho ambiental dos materiais dos produtos. Assim, ao longo de todo o processo de fabrico são registados os consumos de recursos e emissões ambientais e, através da metodologia de avaliação de ciclo de vida, é quantificada a contribuição resultante para impactes ambientais. Esta dissertação visa analisar os possíveis impactes ambientais no decurso do processo de produção de um pavimento flutuante de cortiça, constituído por cortiça, High Density Fibreboard (HDF) e acabamento de superfície, denominado Artcomfort Floating NPC e elaborar de um relatório de suporte, que servirá de base para a DAP do pavimento Artcomfort Floating NPC do sistema do Institut Bauen und Umwelt (IBU). Esta dissertação inclui um relatório de fundo, para a avaliação do ciclo de vida do pavimento flutuante Artcomfort Floating NPC da empresa Amorim Revestimentos, que servirá de base para a elaboração da declaração ambiental de produto (DAP) do mesmo. Para tal, recorreu-se ao software SimaPro para análise dos impactes ambientais das várias fases do processo de fabrico do pavimento em estudo, sendo as fases consideradas, a produção da camada base de cortiça aglomerada, camada backing de cortiça aglomerada, montagem da sanduiche, placa pintada, placa acabada e corte e embalagem. A fase que tem maior contribuição para os impactes ambientais do processo de fabrico do produto, em todas as categorias de impacte analisadas, com exceção da depleção dos recursos abióticos sem combustíveis fósseis, foi a fase de montagem da sanduiche.

A internacionalização de PME: o caso da Carvalheira, Bastos Lda.

Atualmente, a internacionalização é uma estratégia adotada por muitas empresas, independentemente da sua dimensão com o intuito de enfrentar o abrandamento económico no seu mercado doméstico e impulsionar o seu crescimento. No caso das PME, as principais razões que as levam a sair do seu mercado doméstico e a arriscar em mercados externos prendem-se com motivações reativas e muitas vezes exógenas, como sejam a saturação do mercado doméstico, as pressões da concorrência e as relações com os clientes. Assim, a crise financeira no país, aliada à crise no setor da construção civil, leva esta PME portuguesa, do ramo da carpintaria de limpo, a procurar novas oportunidades no exterior. No entanto, como tem consciência da falta de experiência e conhecimento nos mercados internacionais, começa por abordar os mercados numa lógica de procura de novas oportunidades, aproveitando as oportunidades que lhe são dirigidas e vendo nestas uma forma de aprofundar relacionamentos e ganhar experiência neste âmbito. Posteriormente, este conhecimento e experiência permitir-lhe-á enveredar por uma estratégia de internacionalização mais ativa, abandonando/diminuindo a lógica de oportunidade e apostando numa lógica mais estruturada e planeada. Este trabalho, ao tirar proveito de um único estudo de caso, pretende analisar a perspetiva evolutiva da empresa, e como uma estratégia empreendedora, a confiança e a incorporação em redes de relacionamentos facilitam o processo de abertura aos mercados externos.

Natureza morta...edifício com vida: uma arquitetura sustentável para o Serviço de Verificação de Óbitos

Sustainability in buildings, while reducing the impact on the environment, contributes to the promotion of social welfare, to increase the health and productivity of occupants. The search for a way of build that meets the aspirations and development of humanity without, however, represent degradation of the environment, has become the great challenge of contemporary architecture. It is considered that the incorporation of principles that provide a sustainable building with careful choices of design solutions contribute to a better economic and thermal performance of the building, as well as functional and psychological comfort to its users. Based on this general understanding, this paper presents an architecture project aimed to health care whose the solutions adopted follow carefully the relevant legislation and sets his sights on the theme of sustainability. The methodology began with studies on the themes of verification service of deaths, sustainability and those application in construction developed through research in academic studies and analysis of architectural projects, using them like reference for the solutions adopted. Within the project analysis was performed a visit to the verification service of deaths in the city of Palmas in Tocantins, subsidizing information that, plus the relevant legislation, led to functional programming and pre-dimensional of the building to be designed. The result of this programming environments were individual records with information from environmental restrictions, space required for the development of activities, desirable flow and sustainability strategies, that can be considered as the first product of relevance of the professional master's degree. Finally we have outlined the basic design architecture of a Verification Service of Death SVO/RN (in portuguese), whose process of projecting defined as a guiding line of work four points: the use of bioclimatic architecture as the main feature projectual, the use of resources would provide minimal harm to the environment, the use of modulation and structure to the building as a form of rationalization and finally the search for solutions that ensure environmental and psychological comfort to users. Importantly to highlight that, besides owning a rare theme in literature that refers to architectural projects, the whole project was drawn up with foundations in projective criteria that contribute to environmental sustainability, with emphasis on thermal performance, energy efficiency and reuse of rainwater

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
