Tempo para acesso ao tratamento do câncer de mama no Distrito Federal, Brasil Central

PURPOSE: To analyze the time between the first symptom and treatment in patients treated for breast cancer in public hospitals in the Federal District. METHODS: This was a cross-sectional analysis. We interviewed 250 women diagnosed with breast cancer treated in six hospitals of the State Department of Health of the Federal District from November 2009 to January 2011. The time intervals studied were the time between the detection of the symptoms and treatment subdivided into intervals until and after the first medical appointment. The variables were: age, menopausal status, color, educational level, average monthly household income, origin, reason for the initial consultation, staging, tumor size, laterality, metastasis to axillary lymph nodes, neoadjuvant chemotherapy, and type of surgery. The Mann-Whtney test was used to assess the association of these variables with the time intervals until treatment. RESULTS: The mean age was 52 years, with a predominance of white women (57.6%), from the Federal District (62.4%), with a family income of up to 2 minimum wages (78%), and up to four years of schooling (52.4%). The staging of the disease ranged from II to IV in 78.8% of the women. The time between the first symptom and treatment was 229 days (median). After detection of the first symptom, 52.9% of the women attended a consultation within 30 days and 88.8% took more than 90 days to start treatment. Women with elementary school education had a greater delay to the start of treatment (p=0.049). CONCLUSIONS: There was a significant delay to start treatment of women with breast cancer in public hospitals of the Federal District, suggesting that efforts should be made to reduce the time needed to schedule medical appointments and to diagnose and treat these patients.

Expõem ainda, quais foram os fatores preponderantes para a escolha do uso dessa técnica: a rede de persuasão e controle criada e coordenada pela Monsanto e a redução do custo de produção, através da diminuição do uso de herbicidas

Análise e redução de custos e peso em veículo rodoviário de carga reboque linha de eixos

Load transportation in brazilian territory is made difficult by a deficient highway network, result of low maintenance and lack of government supervision. The problem aggravates when we consider the transportation of indivisible loads, mainly because the brazilian highways are not prepared for such task and few companies in Brazil have the necessary equipment suited for this kind of transport. In this dissertation it will be shown the analysis of a specific equipment to transport overweight indivisible loads, called hydraulic modular multi axle trailer. From an existing project (RB.04LE-01), manufactured and homologated in Brazil, it has been studied how the components in this trailer work so it could have been possible to elaborate a new model (RB.04LE-02), with two main objectives: reduction of costs and weight with subsequent increase in the liquid load for roadway transportation. The trailer’s components analyses were made utilizing the theory of fatigue strength of materials and finite element method with the von Misses criteria for a more safety when realizing the calculations

Estudo sobre os fatores que explicam e influenciam a taxa de natalidadade no Brasil

O movimento de controle de natalidade mundial já ocorreu em diversos países desde os séculos passados, principalmente naqueles considerados do primeiro mundo. Os dados obtidos no Brasil demonstram a redução sensível dessa taxa de natalidade, porém de maneira distinta comparada aos dos países tidos como desenvolvidos. Dessa forma, estudou-se a taxa de natalidade brasileira e suas variações ao longo dos anos, no período de 1940 a 2000, tendo em vista as mudanças de fatores no âmbito econômico, social, político e cultural. Esse estudo se fundamentou numa base bibliográfica em que as atividades desenvolvidas foram pautadas na metodologia científica. Os dados de crescimento populacional foram analisados à luz das Teorias Demográficas Malthusiana, Neomalthusiana e Reformistas ou Marxistas, fazendo um comparativo com a Teoria da Transição Demográfica de Thompson. Além disso, o estudo fez uso da pesquisa quantitativa para compreender o seu objeto de interesse, pois os dados e as evidências coletados foram quantificados, organizados, tabulados e preparados para serem submetidos a análises estatísticas e econométricas. Para o estudo foram utilizados dados obtidos no IPEADATA, nos anos de 1991 e 2000, explicados por meio de uma regressão, tendo como variáveis independentes o analfabetismo, o número de domicílios com televisão e energia elétrica, a esperança de vida ao nascer, a freqüência escolar, o número de médicos por habitante, a mortalidade infantil, o número de homicídios por município, a participação da mulher no mercado de trabalho, a população rural, o percentual de pobreza, a renda per capita e a renda de transferências governamentais. Assim, foi possível elaborar um modelo de regressão com dados em painel que mediu a influência dessas variáveis sobre a taxa de fecundidade brasileira. Os resultados indicaram o impacto dessas...

Amostragem de poluentes gasosos e particulados emitidos pela queima de biomassa vegetal

The use of biomass as an energy source has been increasing in Brazil, with emphasis on the use of wood biomass, such as bark, wood chips and sawdust, that after receiving the appropriate treatment can be used in burners for power generation. However, from this burning are emitted fine particles known as particulate matter and a wide range of toxic organic and inorganic components in the form of gases that contribute greatly to air pollution and global warming, affecting human health, the environment and climate. The objective of this project was the quantification of gaseous and particulate, using and evaluating the equipment DR4000 ( Dataram 4 ) sampling of particulates smaller than 2.5μm and EUROTRON ( Ecoline 4000 ) when sampling gaseous pollutants, emitted from the burning of biomass in real time in the firing burner to a chimney attached biomass . We note that there are no specific rules that establish emission limits for particulate matter with diameter less than 2.5μm that are most harmful to human health and the highest concentrations reached about 800000μg/m3, for smaller diameters. It is noticeable the need for sampling of pollutants especially in industries that use biomass to fuel that could be implanted emission control equipment

Ecotécnicas aplicáveis á construção civil no Brasil

This work approaches the main eco-efficient techniques and materials that can be used to ensure the proper functioning of the habitat with the main objective of preserving energy and reducing the ecological impact. The harnessing of energy to run a house using materials in a correct way makes it possible to achieve the goals related to its rational use. So, the more consolidated techniques need to be studied separately to determine the global effect on housing. The results obtained, with the aid of standard NBR15220 ABNT, were a series of ecotécnicas that can be used in 8 relatively homogeneous zones. This study was made to create a public awareness of the current environmental problems that society is facing nowadays and the urgent need to practice responsible use of energy

Reformas estruturais no Brasil na década de 1990 e seu impacto sobre o emprego

O país passou por um período de grandes transformações no último quarto do século XX, os quais afetaram em grande medida a esfera social, política e econômica da sociedade. Dado o enfraquecimento do Estado de Bem Estar Social, e a ascensão do pensamento neoliberal nos anos 1970, houve a revisão do papel do Estado em todo o globo. As reformas neoliberais durante a década de 1990 tiveram um impacto significativo sobre os níveis do produto, e refletiram na redução do emprego até o fim da década, além do surgimento de novas formas de precarização do trabalho. Este trabalho tem como principal objetivo elucidar o impacto destas reformas estruturais sobre o emprego e seus desdobramentos na sociedade

Estudo de caso: aplicação do método DMAIC-White Belt- na redução de latas amassadas em uma produção de leite em pó

This work consists of the implementation of the steps Define, Measure , Analyze , Improve and Control ( DMAIC ) to develop a Six Sigma project in an industry the food industry. The objective was to demonstrate a potential for reducing the occurrence of crushed cans in potting milk powder industry in a White Belt project. The food industry accounts for about 9 % of Brazil's gross domestic product ( GDP ), generating thousands of jobs . Among the major sectors of the food industry is the manufacturing sector of milk , occupies approximately 10 % of the total turnover of the food industry . Brazil is considered today one of the eight largest producers of milk powder in the world. The milk powder is packed , mostly for aluminum cans that are lined internally with varnishes and other materials to protect the milk of metals from aluminum. When the cans are dented food protection is compromised and may lead ingestion causing dis-eases such as botulism. Aiming to solve the problem of dented cans methodology was used as a case study with a quantitative approach through the DMAIC method. Some quality tools used in each step of the project as brainstorming , cause and effect diagram , flowchart , ef-fort and impact matrix, 5W1H , among other Pareto diagram is presented . A survey about the disposal of cans in the company verifying a mean loss and, from this histor-ical , a goal loss was calculated was performed . With the target set we calculated the annual saving design . During application of DMAIC was found that the highest rate of loss occurred in transportation between the factory and the factory that fills cans milk . Several actions were taken to resolve problems that resulted in dented cans and the first two months of phase control it was found that the smaller losses calculated target resulting in a saving for the company. The short time of implementa-tion of the Improve phase did not allow a more detailed a ...
