Produção enxuta aplicada à construtoras de pequeno e médio porte

Against the current need of improvements in construction processes and increased competitiveness on Construction Industry in Brazil, lean construction concepts have spread all over the market, achieving small and medium enterprises. In reason of this, the monograph it is a research based on interviews of small and medium construction enterprises from Vale do Paraíba, São Paulo, Brazil, that focus in identify practices of lean construction implementation and barriers to incorporate these concepts on them. Besides the research, it will be done an analysis and some suggestions to overcome the obstacles appeared

O Ensino de Geometria por meio de atividades investigativas: uma experiência com alunos do primeiro ano do Ensino Médio

This qualitative nature of work was developed with the participation of a group of students enrolled in the first year of high school from a public school of the state of São Paulo, in the city of Taubaté. Their goal was to determine how students deal with geometry tasks in investigative classes. To guide this research was drawn up the following question: As students of the first year of high school express their knowledge of building triangles and quads in classes of investigative activities?. The choice of investigative nature of this activity occurred by enhancing student participation and thus generate a greater chance of it not be guided only by what the teacher wants, but by his own curiosity and using their own tools for this. In the data analysis process stands out the interest generated in students for this type of activity and posture maintained throughout the work, mobilizing their expertise to answer the questions posed

CONFLITOS TERRITORIAIS, RELAÇÕES DE TRABALHO E SAÚDE AMBIENTAL NO AGROHIDRONEGÓCIO CANAVIEIRO NO PONTAL DO PARANAPANEMA (SP)

Essa pesquisa tem como objetivo a análise do conflito pela terra no Pontal do Paranapanema (Estado de São Paulo, Brasil), considerando a disputa pelos recursos hídricos e a degradação da saúde ambiental na área denominada do agrohidronegócio canavieiro. Os resultados da pesquisa indicam que a expansão do cultivo da cana nessa região está provocando o agravamento da saúde dos trabalhadores. Por outro lado, a pesquisa também procura identificar modelos alternativos ao projeto hegemônico de desenvolvimento regional baseado na matriz agrohidroenergética. Para isto, a pesquisa tem como interlocutores diversos tipos de movimentos sociais, como o Movimento dos Trabalhadores Sem Terra e o Movimento dos Atingidos por Barragem, além de lideranças sindicais.

Ecological aspects of the sandfly fauna (Diptera, Psychodidae) in an American cutaneous leishmaniasis endemic area under the influence of hydroelectric plants in Paranapanema river, State of Parana, Brazil

Introduction: An epidemiological study was undertaken to identify determinant factors in the occurrence of American cutaneous leishmaniasis in areas under the influence of hydroelectric plants in Paranapanema river, State of Parana, Brazil. The ecological aspects of the phlebotomine fauna were investigated. Methods: Sandflies were sampled with automatic light traps from February 2004 to June 2006 at 25 sites in the urban and rural areas of Itambaraca, and in Porto Almeida and Sao Joaquim do Pontal. Results: A total of 3,187 sandflies of 15 species were captured. Nyssomyia neivai predominated (34.4%), followed by Pintomyia pessoai (32.6%), Migonemyia migonei (11.6%), Nyssomyia whitmani (8.8%), and Pintomyia fischeri (2.7%), all implicated in the transmission of Leishmania. Males predominated for Ny. neivai, and females for the other vector species, with significant statistical differences (p < 0.001). Nyssomyia neivai, Pi. pessoai, Ny. whitmani, Brumptomyia brumpti, Mg. migonei, and Pi. fischeri presented the highest values for the Standardized Species Abundance Index (SSAI). The highest frequencies and diversities were found in the preserved forest in Porto Almeida, followed by forests with degradation in Sao Joaquim do Pontal and Vila Rural. Conclusions: Sandflies were captured in all localities, with the five vectors predominating. Ny. neivai had its highest frequencies in nearby peridomestic environments and Pi. pessoai in areas of preserved forests. The highest SSAI values of Ny. neivai and Pi. pessoai reflect their wider dispersion and higher frequencies compared with other species, which seems to indicate that these two species may be transmitting leishmaniasis in the area.

Study of postures in sugarcane cutters in the Pontal of Paranapanema-SP, Brazil

The expansion of sugarcane monoculture in Brazil in the last decades has pointed out to the necessity of considering the question of sugarcane cutters occupational health. In this work we present a cross-sectional study aiming to examine the occupational posture of a group of sugarcane cutters, which work in a cane field located in the region of Pontal do Paranapanema-SP, Brazil. The study was made using the Ergonomic Analysis of Work - EAW methodology and the postural analysis method by Win-OWAS. Through the obtained records of postures, it was observed that during a workday the sugarcane cutters remain standing erect on two legs or in one leg 66% of the time and that their trunk remain tilted and in rotation, according to 63% of the positions categorized. It was also observed that the sugarcane cutter trunk performs repetitive and boundless movements during his routine of work, which can expose this individual to additional wear of their musculoskeletal functions. The activities in which the individual engages have favorable or adverse influence on his posture. The repetitive movements involved in specialized occupations are equivalent to repeated exercises, thus may be responsible for the excessive development of certain muscle groups. The study suggests that the postures adopted by sugarcane cutters can overload their musculoskeletal system and predispose the cutters to work-related musculoskeletal diseases.

The fish fauna in the fish passage at the Ourinhos Dam, Paranapanema River

The composition and abundance of the fish assemblage were evaluated in the fish ladder of Ourinhos Dam, the newest dam (closed in 2005) in the cascade of dams constructed on the Paranapanema River. Samplings were carried out three times on a diel cycle, in three sampling periods, two in the warm season and one in the cold season of 2008 - 2009. The ladder was closed and emptied and the entire fish assemblage was sampled and identified. Most individuals were released alive downstream of the dam. The assemblage found in the ladder was compared with the fish fauna sampled in the reservoir and in downstream sites, in the same period. Twenty seven species and a total of 4682 individuals were caught in the ladder. Pimelodus maculatus was the only migratory species, which was caught in low number in the ladder (0.04% of the total captured), where small sedentary species predominated. The most abundant species were the non-migratory Apareiodon affinis, Bryconamericus stramineus, Astyanax fasciatus and Parodon nasus. Individuals observed in the ladder's window were moving up-and down the passage. The fish ladder is a microhabitat inhabited by an abundant association of benthic organisms that is probably used as a food resource for the fish assemblage in the ladder. The similarity between the fish fauna in the ladder and that of the Ourinhos Reservoir was low (26%). The species richness of migrants in the stretch between the uspstream reservoir (Chavantes) and the downstream one (Salto Grande), before the Ourinhos dam closure (23 species) was reduced to 16 and 12 species in Salto Grande and Ourinhos reservoirs, respectively, after the dam closure, and to a single species in the ladder.

Fatores de risco para hipertensão arterial entre estudantes do ensino médio

OBJETIVO: Identificar os valores pressóricos e estimar a frequência de fatores de risco para a hipertensão arterial entre estudantes do ensino médio. MÉTODOS: Estudo descritivo de corte transversal, desenvolvido em escolas da Região Sudeste brasileira. Fizeram parte da amostra 184 adolescentes matriculados na segunda série do ensino médio, em 2009. Além da mensuração das variáveis clínicas, foram aplicados instrumentos para identificação de fatores de risco associados à doença hipertensiva. RESULTADOS: A alteração pressórica foi um parâmetro detectado em 22,3% da amostra. Dentre os fatores de risco investigados, o histórico familiar de doenças cardiovasculares e o consumo de álcool foram os mais prevalentes. CONCLUSÃO: Há necessidade de valorizar as medidas de prevenção primária e detecção precoce da hipertensão arterial entre adolescentes, com especial atenção para a avaliação dos antecedentes familiares e adoção de hábitos de risco.
