Eco postal: um programa socioambiental com gera????o de emprego e renda

Na Empresa Brasileira de Correios e Tel??grafos (ECT), um grande n??mero de empregados recebe uniformes com periodicidade semestral, o que inclui tamb??m a troca peri??dica dos malotes inutilizados pelo desgaste. Por quest??es de seguran??a, todo esse material inserv??vel era destinado ao aterro sanit??rio. Mas, desde 2004, foi encontrado um novo destino para esses objetos a partir das cooperativas formadas em conv??nio com a Universidade Federal do Paran??, Associa????o Comercial do munic??pio de Toledo e Organiza????es N??o-Governamentais (ONGs). As cooperativas transformam artesanalmente esse material em v??rios produtos que geram emprego e renda, especialmente para as fam??lias que, em muitas situa????es, viviam do subemprego. Isso demonstra a import??ncia que a empresa confere ??s a????es de responsabilidade social que ultrapassam a oferta de servi??os com qualidade ?? comunidade, assegurando que todo o processo de trabalho seja feito de forma socialmente respons??vel. Este programa gera emprego e renda para aproximadamente 50 fam??lias em todo o estado, com projeto de amplia????o para outras regi??es

Are public officials really less satisfied than private sector workers?A comparative study in Brazil

This research aims to compare the public and private sectors with regard to satisfaction at work. We conducted a survey with 670 professionals from both sectors in Brazil. The results of variance analysis confirm previous researches indicating that public officials are less satisfied with their work than private sector workers. However, this result does not repeat when we evaluate the satisfaction dimensions. For instance, public officials reported being more satisfied than private sector workers with regard to social environment and work stability. Unexpectedly, the results suggest that there is no difference between these sectors when we analyze the satisfaction with supervision. Therefore, this article is relevant for Brazilian managers, by offering an empirical research on the distinction between public and private. The article also discusses the theoretical implications, since Brazilian findings do not completely support the international literature.

O sistema postal brasileiro em transformação: propostas e mudanças na regulação do mercado e na reestruturação do modelo organizacional da Empresa Brasileira de Correios e Telégrafos (1994-2011)

Objetiva-se neste artigo responder a seguinte questão: quais foram as propostas e as mudanças nos mecanismos de regulação do mercado postal brasileiro e na estrutura organizacional da Empresa Brasileira de Correios e Telégrafos (ECT) entre 1994 e 2011? Verifica-se que, entre 1994 e 2002, a proposta do governo federal, apresentada em 1999 por meio da "Nova Lei postal", previa a criação do Sistema Nacional de Correios, liberalizando o mercado postal, criando um órgão regulador e transformando a ECT em uma empresa de economia mista. Apesar da não aprovação do projeto de lei, algumas de suas propostas foram retomadas, a partir de 2008, pelos diagnósticos e propostas do governo Lula para reestruturar o setor postal brasileiro. As propostas subsidiaram a aprovação da Lei nº 12.490 de 2011, que internacionalizou a ECT, ampliou os segmentos de mercado da empresa e a reestruturou com base no modelo das sociedades anônimas.

Análise do produto "Plano Poupança Reforma" na óptica do particular: Abordagem através de instituições bancárias, sociedade financeira postal e uma sociedade de seguros

As nossas reformas estão cada vez mais em risco devido ao progressivo aumento da esperança média de vida da população. Sendo cada vez mais escasso o tributo dos contribuintes líquidos, prevê-se assim que dentro de 25 a 30 anos a Segurança Social não terá capital para pagar a totalidade das reformas. Ainda será possível contar com as pensões do Estado? Seguramente! Mas serão suficientes para assegurar um nível de vida aceitável aos futuros pensionistas? Muito provavelmente não! Antecipando esta realidade é tempo de começarmos a pensar na nossa reforma procurando as melhores soluções para constituir uma complemento de reforma. Constituir um Plano de Poupança Reforma (PPR) pode revelar-se difícil nos dias de hoje devido pouco rendimento disponível, mas quanto mais cedo começar a poupar para a reforma, mais fácil será, face a um futuro incerto. Apurou-se que existem disponíveis, vários tipos de PPR, que diferem no capital e na rentabilidade, consoante o horizontal temporal e o objectivo do investidor. Se a estratégia se baseia no futuro, faz todo o sentido o investidor seleccionar investimentos de longo prazo e que ofereçam possibilidades de rentabilização superiores à média. Se o investidor pretender uma rentabilidade a curto prazo através de investimentos diversificados, não encontra vantagens em optar por investimentos a longo prazo, porque estes possuem limitações nas questões de liquidez ou acarretar encargos significativos (comissões). O objectivo principal deste trabalho é conhecer e perceber a estrutura conceptual do objecto, nomeadamente através da aprendizagem de conceitos e cálculo; identificação dos problemas do produto; estratégia de escolha do produto; a capacidade de decisão.

XRCC3241 Polymorphism influence on genotoxicity biomarkers frequency in workers occupationaly exposed to formaldehyde

Formaldehyde (FA) is ubiquitous in the environment and is a chemical agent that possesses high reactivity. Occupational exposure to FA has been shown to induce nasopharyngeal cancer and has been classified as carcinogenic to humans (group 1) on the basis of sufficient evidence in humans and sufficient evidence in experimental animals. The exposure to this substance is epidemiologically linked to cancer and nuclear changes detected by the cytokinesis-block micronucleus test (CBMN). This method is extensively used in molecular epidemiology, since it determines several biomarkers of genotoxicity, such as micronucleus (biomarkers of chromosomes breakage or loss), nucleoplasmic bridges (biomarker of chromosome rearrangement, poor repair and / or telomeres fusion) and nuclear buds (biomarker of elimination of amplified DNA). The gene X-ray repair cross-complementing group 3 (XRCC3) is involved in homologous recombination repair of cross-links and chromosomal double-strand breaks and at least one polymorphism has been reported in codon 241, a substitution of a methionine for a threonine.

Evaluation of the influence of the ADH3 ILE349VAL polymorphism in the frequency of genotoxicity biomarkers in workers exposed to formaldehyde and tobacco smoking

Formaldehyde (FA) is a colourless gas widely used in the industry and hospitals as an aqueous solution, formalin. It is extremely reactive and induces various genotoxic effects in proliferating cultured mammalian cells. Tobacco smoke has been epidemiologically associated to a higher risk of development of cancer, especially in the oral cavity, larynx and lungs, as these are places of direct contact with many carcinogenic tobacco’s compounds. Genetic polymorphisms in enzymes involved in the metabolism are very important and can make changes in the individual susceptibility to disease. Alcohol dehydrogenase class 3 (ADH3), also known as formaldehyde dehydrogenase dependent of glutathione, is the major enzyme involved in the formaldehyde oxidation, especially in the buccal mucosa. The polymorphism in study is a substitution of an isoleucine for a valine in codon 349. The cytokinesis-blocked micronucleus assay (CBMN) in human lymphocytes is one of the most commonly used methods for measuring DNA damage, namely the detection of micronucleus, nucleoplasmic bridges, and nuclear buds, classified as genotoxicity biomarkers.

Lyme Disease: antibodies against Borrelia burgdorferi in farm workers in Argentina

Lyme Disease is a tick-borne (specially by Ixodes ticks) immune-mediated inflammatory disorder caused by a newly recognize spirochete, Borrelia burgdorferi. Indirect fluorescent antibody (IF) staining methods and enzyme-linked immunosorbent assay are frequently relied upon to confirm Lyme borreliosis infections. Although serologic testing for antibodies has limitations, it is still the only practical means of confirming B. burgdorferi infections. Because we have no previous report of Lyme disease in human inhabitants in Argentina, a study was designed as a seroepidemiologic investigation of the immune response to B. burgdorferi in farm workers of Argentina with arthritis symptoms. Three out of 28 sera were positive (#1,5 and 9). Serum # 1 was positive for Immunoglobulin G at dilution 1:320, serum # 5 and # 9 both to dilution 1:160; while for Immunoglobulin M all (#1, 5 and 9) were positive at low dilution (1:40) using IF. The results showed that antibodies against B. burgdorferi are present in an Argentinian population. Thus caution should be exercised in the clinical interpretation of arthritis until the presence of B. burgdorferi be confirmed by culture in specific media.

Effects of the interaction of tobacco smoke and alcohol consumption on buccal micronucleus in workers exposed occupationally to formaldehyde

Occupational exposure to formaldehyde (FA) has been shown to induce nasopharyngeal cancer and has been classified as carcinogenic to humans (group 1) on the basis of sufficient evidence in humans. Tobacco smoke has been associated to a higher risk of development of cancer, especially in the oral cavity, larynx and lungs, as these are places of direct contact with many carcinogenic tobacco’s compounds. Alcohol is a recognized agent that influence cells in a genotoxic form, been citied as a strong agent with potential in the development of carcinogenic lesions. Epidemiological evidence points to a strong synergistic effect between cigarette smoking and alcohol consumption in the induction of cancers in the oral cavity. Approximately 90% of human cancers originate from epithelial cells. Therefore, it could be argued that oral epithelial cells represent a preferred target site for early genotoxic events induced by carcinogenic agents entering the body via inhalation and ingestion. The MN assay in buccal cells was also used to study cancerous and precancerous lesions and to monitor the effects of a number of chemopreventive agents.

Micronuclei in peripheral blood lymphocytes in formaldehyde occupationally exposed workers

Formaldehyde (CH2O) the most simple and reactive of all aldehydes, is a colorless, reactive and readily polymerizing gas at normal temperature. It has a pungent, suffocating odour that is recognized by most human subjects at concentrations below 1 ppm. According to the Report on Carcinogens, formaldehyde (FA) ranks 25th in the overall U.S. chemical production with more than 11 billion pounds (5 million tons) produced each year. Is an important industrial compound that is used in the manufacture of synthetic resins and chemical compounds such as lubricants and adhesives. It has also applications as a disinfectant, preservative and is used in cosmetics. Estimates of the number of persons who are occupationally exposed to FA indicate that, at least at low levels, may occur in a wide variety of industries. The occupational settings with most extensive use of formaldehyde is in the production of resins and in anatomy and pathology laboratories. Several studies reported a carcinogenic effect in humans after inhalation of FA, in particular an increased risk for nasopharyngeal cancer. Nowadays, the International Agency for Research on Cancer (IARC) classifies FA as carcinogenic to humans (group 1), on the basis of sufficient evidence in humans and sufficient evidence in experimental animals. Manifold in vitro studies clearly indicated that FA is genotoxic. FA induced various genotoxic effects in proliferatin cultured mammalian cells. A variety of evidence suggests that the primary DNA alterations after FA exposure are DNA-protein crosslinks (DPX). Incomplete repair of DPX can lead to the formation of mutations.

Biological monitoring of aflatoxin (AFB1) in workers of swine and poultry production

Although a great body of literature exists concerning the ingestion of food contaminated with aflatoxin, there are still few studies regarding mycotoxin inhalation in occupational settings. Since mycotoxins are relatively non-volatile, inhalation exposure is cause by inhalation of airborne fungal particulates or fungi-contaminated substrates that contain aflatoxin. We intend to know if there is occupational exposure to aflatoxin in Portuguese poultry and swine production. A total of 19 individuals (11 swine; 8 poultry) agreed and provided blood samples during the course of this investigation. Measurement of AFB1 was performed by ELISA. The samples were treated with pronase (Merck), wash in a Column C18 and purification was made with immunoaffinity columns (R.biopharma), specific for AFB1. It was applied statistical test (Mann-Whitney) to verified statistical difference in AFB1 results between the two settings. Results varied with concentrations from workers have higher aflatoxin values, probably because poultry activities are promoter of particles exposure. Only women’s in both settings have results
