Tecnologia social para autogest��o: um estudo em empreendimento econ��mico solid��rio do Rio Grande do Norte

The theme of this dissertation is social technology for self-management: a study in economic enterprise supportive of Rio Grande do Norte. The research aimed to obtain evidence that the reapplication of technology management, basic economic-financial and pricing, as production costs, has the potential to contribute to the self-management of APABV. The social technology and self-management are theoretical frameworks used and where workers are central figures in both the generation and replication of technologies that are compatible with their realities, as in the conduct and management approach adopted by them in their venture, they are makers decisions. To achieve the proposed objective was accomplished participatory research, which was used in addition to document analysis, participatory methodologies such as the construction of the DRP, group interview, experience in the production environment and family of entrepreneurs APABV. This research allowed the management technologies such as spreadsheets controls basic economic and financial costs, when socialized and understood by workers has the potential informational and become part of their daily decision-making process of the project, making up social technology

Caracteriza����o parcial e atividades farmacol��gicas do extrato rico em polissacar��deos sulfatatos da angiosperma marinha Halodule wrightii

Sulfated polysaccharides (PS) are biomolecules with a great biotechnological potential. There are few data about PS from high plants. In addition, pharmacological activities of PS from plants have not been carrying out. The aim of this work was extract PS from the angiosperm Halodule wrightii and study their anticoagulant and antioxidant activities. Histological analysis showed the presence of the PS manly in the roots. A polysaccharide-rich extract was obtained from H. wrightii by proteolysis followed by methanol and TCA precipitation. Chemical, infra-red analysis and agarose gel electrophoresis in 1.3 diaminopropane acetate buffer confirmed the presence of sulfated polysaccharides made by glucose, galactose, xylose and sulfate residues in the proportion 1: 0,9: 1: 1. In addition polyacrilamide electrophoresis have shown that extract is mainly compose by 11kDa sulfated polysaccharides. Pharmacological analysis have shown total antioxidant capacity (CAT) that resulted in 15,21 μg for equivalent of ascorbic acid, scavenging activity of the DPPH radical with 41,36 % of scavenging, activity of reducing power with the maximum of 0,290 nm (50 % of vitamin C activity) and scavenging activity superoxide radical (O2-) with a maximum of 32,23 %. Chelating activity of metal less than 4% and scavenging activity of the radical hydroxyl (OH-) less than 2%. Time of activated partial tromboplastin (aPTT) doubling the time of coagulation from 20μg of and protrombin time (PT) was not present. The data indicate that PS from Halodule wrightii could be considered for future applications in medicine, food production or cosmetic industry

Reestrutura����o do setor industrial e transforma����o do espa��o urbano de Campina Grande PB : a partir dos anos 1990

The central objective of this thesis is studying the changes in the industrial sector of Campina Grande-PB, in the years 1990, about the size of that space and urban sector. The hypothesis that guides this work is that there was a reconfiguration and industrial space in recent years, the result of the restructuring of productive capital and, secondarily, public policies - economic, urban etc. - implemented in the municipality in the years 1990. This reconfiguration industrial meant thepredominance of certain productive segments of the industry and the shift towards urban-industrial areas (industrial districts). This work is guided in these two axes to explain the changes in the industrial campinense and its consequent impact on the urban development of Campina Grande. It is understood by reconfiguration industrial changes in industrial structure, namely the preponderance of one or more productive segments on the other, changing the scenario of production, employment and the number of establishments. In this study, are considered as institutional structures of support and assistance to industry, the various institutions that directly and indirectly, contribute to the development of productive activity. These structures are the first to undergo institutional changes, physical and policies because of intrinsic connection with the industry. The institutional structures contribute to the development of industrial activity and urban development. In Campina Grande, these institutions are important for facilitating the development of certain segments. In this work, sought to identify the current configuration industrial campinense, explaining how the restructuring of production transformed the industry, modifying the urban space in Campina Grande - PB, to direct itself to specific urban areas, from the early 1990

Suplementa����o como estrat��gia de produ����o de carne de qualidade em pastagens tropicais

O manejo do pastejo e a suplementa����o estrat��gica permitem maximizar a produ����o de carne bovina em pastagens de forma sustent��vel. A intensidade de pastejo influencia diretamente o crescimento individual, taxas de aparecimento e mortalidade de perfilhos, a determinar o ac��mulo de forragem e a estrutura do dossel. Dessa forma, nas ��guas, �� fun����o do manejo do pastejo adequar a frequ��ncia e intensidade de desfolha����o para que o animal possa colher forragem com idade fisiol��gica e valor nutritivo adequados. A idade e tamanho dos perfilhos determinam a propor����o de tecidos de suporte lignificados que reduzem a digestibilidade da forragem. No per��odo seco, o manejo do pasto e a estrat��gia de diferimento, ao final do per��odo das ��guas, s��o determinantes na obten����o de forragem de melhor valor nutritivo. Assim, o manejo das pastagens visa, primeiramente, �� produ����o de forragens com altos teores de fibra potencialmente digest��veis. A partir de ent��o, a caracteriza����o da quantidade e qualidade da forragem s��o primordiais �� adequa����o dos nutrientes fornecidos, via suplementos, para otimizar a utiliza����o dos recursos forrageiros basais. A suplementa����o da dieta dos animais em pastejo, com concentrado, permite aumentar o desempenho dos animais, o que reduz a idade de abate e melhora a qualidade da carca��a e da carne obtida, al��m dos benef��cios na prepara����o dos animais terminados em confinamento. Portanto, o manejo do pastejo e a suplementa����o da dieta dos animais permitem aumento de produtividade e maior qualidade dos produtos.

A minera����o artesanal e de pequena escala em pegmatitos e cer��mica no munic��pio de Parelhas, regi��o do Serid��/Rio Grande do Norte

The working conditions, occupational health, occupational illness and workers quality of life, usually referring to the artisanal activities and the workers with a poor professional support. Because this reality is still present in locals without good infrastructure of social and economic attention, there is a need for a broad knowledge of problems related to the productive processes that include features of unsanitary and unhealthy. Despite the intense process of industrialization promoted by globalization and the growth of developing nations like Brazil, the activities of artisanal and small-scale mining are still suffering from the marginalization of their production processes and their workers. This dissertation deals with the description of mineral-based activities (MBA), especially the activities related to production processes of extraction and processing of red pottery and minerals in pegmatites in Parelhas city, Serid��, Rio Grande do Norte, which are conducted by small mining companies or artisanal miners. The study of the work process was based on direct observation, photographic documentation, ergonomics, health and occupational safety analysis, interviews and structured questionnaire with workers of the two activities. The results indicate the need for improvement in both workplaces (red pottery and pegmatites), adaptation of workers to safety standards specific to the workplace, more attention and care related to ergonomics and occupational safety, greater importance to economic and social relations among performed activities, workers and firms of mineral branch and better and greater integration of social policies, supported by different sectors of society with the intention of transforming the current social, cultural, labor and education situation

Pol��ticas p��blicas e trabalho no transporte alternativo na Amaz��nia: moto t��xi

Analisa a problem��tica dos transportes urbanos, no contexto da Regi��o Amaz��nica. O estudo tem o objetivo de descrever e analisar o transporte de moto-t��xi nas cidades de Castanhal, no estado do Par��, e Tef��, no estado do Amazonas, como uma amostra de uma realidade dessa Regi��o, frente ��s necessidades da produ����o (ind��stria privada de motocicleta) e da reprodu����o (grupo de pessoas). O estudo foi: a) explorat��rio, porque h�� pouco conhecimento acumulado e sistematizado sobre o tema; b) explanat��rio, em raz��o da busca de rela����es entre as vari��veis; e c) descritivo, pelo motivo de que se estimou freq����ncias de elementos com determinada propriedade ou caracter��stica quantitativa. A pesquisa emp��rica obedece a um plano amostral. A busca por conhecimento sobre o transporte alternativo se deu por meio da pesquisa bibliogr��fica. A conclus��o desta exposi����o cient��fica �� que a aus��ncia de pol��ticas p��blicas de transporte urbano em um contexto de desestrutura����o do mercado de trabalho contribui para o surgimento de servi��os de transportes inadequados. Esses servi��os t��m se constitu��do, muitas vezes, numa ��nica alternativa de transporte urbano, inadequado pela perspectiva da seguran��a, e tamb��m numa ��nica oportunidade de trabalho, por��m excludente do rol de benef��cios capaz de reduzir os riscos sociais dos trabalhadores. Neste sentido, aceita-se a hip��tese de que a crescente necessidade por transporte alternativo tem se justificado pela aus��ncia de adequadas pol��ticas p��blicas de transporte e emprego.

Vulnerabilidade de agricultores familiares da cadeia de produ����o de biodiesel de dend�� �� extremos de precipita����o na comunidade ��guas Pretas, Moju (PA)

Os extremos clim��ticos impactam negativamente o agroneg��cio brasileiro e amea��am o desenvolvimento das comunidades rurais que s��o altamente dos recursos naturais. Por isso �� fundamental estudar-se a cadeia produtiva de dend�� (Elais guineensis Jacq.) de ��leo diante de futuros riscos clim��ticos, devido o Estado do Par�� ser o maior produtor nacional de dend�� e a cadeia ser estruturada com a integra����o da agricultura familiar �� cadeia agr��cola. O objetivo desta pesquisa foi de analisar as vulnerabilidades dos agricultores familiares da Comunidade ��guas Pretas do munic��pio de Moju, Estado do Par��, inseridos na cadeia de produ����o de biodiesel de dend��, diante dos extremos de precipita����o. A pesquisa foi desenvolvida em dois momentos: o primeiro analisou os extremos clim��ticos da s��rie temporal de precipita����o de 1981 a 2009 empregando o m��todo descritivo e dos quantis, e o segundo momento analisou a vulnerabilidade dos agricultores atrav��s de vari��veis/indicadores de desvantagem socioecon��mica, tecnol��gica e de percep����o, que representavam situa����o de vulnerabilidade. Para a identifica����o de vulnerabilidade dos agricultores foi utilizado a an��lise fatorial por componentes principais, a elabora����o de ��ndices de vulnerabilidade clim��tica e a an��lise agrupamento, onde foram alocados 22 agricultores em cinco categorias de classifica����o r��definidas. Os resultados obtidos mostraram que a ocorr��ncia de extremos muito secos e muito chuvosos na s��rie de dados entre os anos de 1981 a 2009 do munic��pio de Moju (PA). O risco clim��tico identificado no munic��pio representa grande amea��a �� produ����o de dend��, uma vez que os impactos dos extremos de precipita����o sobre a planta v��o desde dist��rbios nas fases de desenvolvimento at��, a redu����o parcial e total da produ����o dos cachos de dend��. Estes impactos em longo prazo, afeta diretamente os agricultores familiares que s��o dependentes da venda exclusiva dos cachos de dend�� �� agroind��stria, assim como compromete aos objetivos de inclus��o social e produ����o de energia renov��vel do Programa de biodiesel. Os agricultores familiares da comunidade ��guas Pretas integrados a cadeia de produ����o de biodiesel de dend�� reagiram de formas distintas, considerando fatores socioecon��mico, tecnol��gico e de percep����o, sendo distribu��dos em cinco categorias de vulnerabilidade (alta, m��dia alta, m��dia, m��dia baixa e baixa). Os grupos de vulnerabilidade de maior interesse na pesquisa foram de alta e baixa vulnerabilidade, correspondentes a 14% (3 agricultores) e 18% (agricultores), respectivamente, do total de agricultores entrevistados. O grupo de alta vulnerabilidade foi caracterizado por agricultores que utilizaram com baixa efici��ncia a maior parte das vari��veis de desvantagens, indicando dificuldades de competir e adaptar-se, em caso de extremos clim��ticos. No grupo de baixa vulnerabilidade foi caracterizado por agricultores que usam com efici��ncia todas as macrovari��veis estudadas, mostrando vantagens socioecon��micas, tecnol��gicas e de percep����o. Este grupo se mostrou mais adaptado em caso de extremos de clima, dentro da cadeia de biodiesel, podendo ser par��metros para elabora����es de estrat��gias de adapta����o local. A percep����o do risco e os fatores levantados mostraram-se ser um forte recurso para analisar a situa����o de vulnerabilidade dos agricultores locais. A percep����o do agricultor �� orientada segundo suas convic����es e experi��ncias di��rias, sendo determinantes para elabora����o de estrat��gias adaptativas para enfrentar extremos clim��ticos.

Cria����o e implanta����o de procedimentos log��sticos em uma ind��stria de m��veis: estudo de caso

The Brazilian construction is with high production which resulted in many service industries and also for businesses that work in conjunction with it. For the furniture industries would not be different, since they are intimately involved with the construction. To meet the demand for furnishings in Brazil, some clusters of industries have developed in recent years, as in the case of Uba (MG), Arapongas (PR) and Bento Gon��alves (RS). For industries sector can always increase its production combining quality and customer satisfaction, is necessary for their production procedures are studied and improved every day. The aim of this research is to propose a solution for simple information system involving the issue of tracking parts of the furniture produced in an industry custom furniture that depend on outsourced services. The research occurred during four months of the year 2013 for the observation of the production of the industry, where possible observing interference could be carried out with the aim of obtaining improvements in the production line. It is concluded that control of the finished product in a custom furniture industry is a very complex work, because the information system must transmit information faithful, which has not happened formerly, but after the implementation of the identification system was significant improvement the transfer of information between sectors mounts internal and external furniture
