The intestinal parasites are an important healthy problem to human population worldwide. The consumption of vegetables is one of the major routes of transmission of this pathogens. This study aimed to determine the frequency and diversity of intestinal parasites transmitted by vegetables sold in the metropolitan region of Belém-PA and its relation to the seasonal climate of the region. It was used 252 samples of three species of vegetables, of which 84 were of lettuce (Lactuca sativacurly variety), 84 were watercress (Nasturtium officinale) and 84 were coriander (Coriandrum sativum) purchased in open markets, gardens and in a supermarket, from November of 2008 to December of 2009. Each samples was washed with 500ml of PBS, permitting the spontaneous sedimentation and centrifuging 30 ml of the final sediment. The final sediment was analyzed in an optical microscope. The levels of contamination of the three species of vegetables were obtained by the monthly average of intestinal parasite structures identified in each vegetable and by the total number of parasites identified in the samples of each open market, garden and supermarket. In the results obtained in the microscopic analysis of samples were applied the Chi-square and Fisher's Exact Test to determine the existence or not of significant differences between these results. It was used the significance level α ≤ 0.05. This microscopic analysis showed a contamination of 100% of the samples at open markets, gardens and supermarket included in the study, there isn’t statistical difference in overall frequency of parasites among them. Strongyloides stercoralis was the most prevalent parasite, followed by complex Entamoeba histolytic / dispar and the hookworms, both in samples from the gardens, as in samples of the open markets and the supermarket. The cress and lettuce had higher rates of parasitic contamination that coriander. It had been characterized seasonal influence on the intensity of parasites in vegetables investigated because there was statistical difference between the results obtained with a higher prevalence of parasites in samples of summer, for the samples of winter. There wasn’t also statistically significant difference between the monthly averages of contamination of vegetables sold in open markets, gardens and supermarket, indicating that the hygienic conditions under which the vegetables are sold, although important to keep their flavors, have less influence on levels of parasitic contamination, which seems to be associated with the place and growing conditions these plants. These datas permit a good level of comparison to future studies.

“A gente tem uma vida lá fora...”: relações entre gestão de recursos humanos e sociabilidade das pessoas empregadas nos supermercados da Região Metropolitana de Belém
(Universidade Federal do Pará, 2009-05-04) GONÇALVES, Ida Lenir Maria Pena; MANESCHY, Maria Cristina Alves; http://lattes.cnpq.br/5129734199358770
The management of human resources (HR) represents a theorical approach of business management focused on organization of work to its best advantages and, in particular, the involvement of employees in the aims of the company. The management practices focus not only on the work itself, but also in complex way in social interactions occurred in the workplace, as well in the personal life of workers, in accordance with the assumptions and practices of the prevailing style f management. This work demand to know the nature of the correlations between management of human resources and sociability of workers, videlicet, their ability to make and keep various social ties, form the point of view of workers. To reach these aims, was taken as empirical reference four networks supermarkets from the urban region of Belém, Pará. This sector is a great employer, and has been modernized significantly in the last two decades, implementing some procedures in managements of humans resources and remains under strong competition from national and international groups that found in other capitals of the country. The methodology includes systematic observations, document analysis, general interview guide approach and deep-standardized open-ended interview, respectively with three hundred and eighty and fourteen workers, this last ones selected among those in the larger sample. The interviews versed about social and demographic attributes, occupational and career patterns of professional and personal relationship. Covered, too, the perceptions about rules and attitudes into workplace, based on the standards of the service manuals of business. This includes thirty-four items on a scale of Lickert. These items were arranged in factors, two on the management—quality of work (QW) and introjections of organizational standards (OS)—and three on sociability—trust, maintenance and usefulness of relations (UR) at work. The interviewed answered to items, adjusting the degree of their perception of each. These data were submitted to exploratory statistical technique Correspondence Analyses (CA) in order to verify the correlation between the factors of scale and characteristics of respondents. About the correlations between management and sociability, excel in first the work scheme. Long days of work, variables scale. Long daily breaks and the policy of in-service qualification (on the job) absorb nearly the entire time the employee to maintain personal relations and hinder or even extend those trained in the work environment beyond this space. Also hinder invest in studies, another area of sociability, what surprises in a sample whose predominant age range did not exceed thirty years and whose occupation has little chance of career. In this framework of restrictions, the condition of gender and family were relevant, because women, in particular mothers, reported less leisure activities, in little groups and with minimal presence of workmates, compared to men. Furthermore, we found some cases of people which made affective relationships into the workplace, even the coexistence is restricted to the company. Another striking feature was the dependence on family support for the exercise of labor activity and to face the vicissitudes of the labor market. The importance of family ties was reinforced by the long time of residence in the same neighborhood and, in significant proportion, in the same home, in several cases the housing was close or in the same house of parents or parents-in-law, facilitating the mutual aid. Another aspect that stood out the management of human resources was the perceived vagueness in the criteria for professional growth and application of standards, contributing to the existence of conflicts veil. To establish social ties, the employees place a selective trust, expressed in a few people who are confident in the work. It is worth noting here also a small variation between men and women, because men trust more than women in their workmates. The Correspondence Analysis showed sensitive differences of perception on quality of work and introjections of rules among workers with the first record in the labor book and those with previous experience in a formal work. The first notice a more effective control (surveillance) of management and express less agreement with organizational rules, while the others (the second) do not realize the control as the same way and is seen as complying with these rules. These results were interpreted as arising from different previous trajectories, in formal or informal labors, or because it is the first job. Cannot be said that the restrictions on sociability are due exclusively to characteristics of management in this sector, in view the incidence of another factors, as the social-economic condition of the family or the time of employment, on average two years among the respondents, which may have contributed to these results.
