O impacto das diferenças culturais na rotina de trabalho de uma tripulação marítima composto por brasileiros e estrangeiros

Trabalhar embarcado no mesmo navio, pode representar um desafio para os tripulantes estrangeiros e brasileiros da empresa Alfa Navegações, devido às diferenças de valores e crenças dessas culturas manifestas no dia a dia desta tripulação marítima. O principal objetivo nesta dissertação é sinalizar impactos na socialização do convívio a bordo entre tripulação mista. Esta pesquisa investigou a construção de um cotidiano intercultural a partir da convivência entre brasileiros e estrangeiros na filial brasileira da empresa Alfa Navegações. O marco teórico foi construído por meio de fundamentos sobre cultura organizacional, relações interculturais e cultura brasileira para compreensão e análise do cotidiano. A metodologia de pesquisa adotada neste trabalho foi o estudo de caso, com ênfase qualitativa. Foi utilizada a entrevista semiestruturada como instrumento principal de coleta de dados. Concluiu-se que as barreiras culturais na comunicação e na adaptação dos tripulantes no convívio intercultural recaem no idioma. Isto reforça os conceitos expostos no marco teórico sobre a necessidade do treinamento intercultural e aprendizagem de outro idioma para auxiliar o convívio entre culturas diferentes. Com isso, notou-se a necessidade de aprender a lidar com outras culturas, tendo em vista o novo cenário internacional, devido ao aumento do trânsito de pessoas e de ideias de fontes culturais diferentes, e que nas relações sociais a questão intercultural tornou-se crucial. Isto ocorre não somente com aqueles que aceitam o desafio de viver ou trabalhar no exterior, mas também com aqueles que recebem estes profissionais e com eles convivem no cotidiano.

Fisioterapia e sociedade: ações do Sistema Único de Saúde no Rio Grande do Norte

The work has objective to present actions of Physiotherapy, developed by SUS in the State of Rio Grande do Norte; discuss under the humanization point of view such actions of health; discuss the importance of physioterapy to the Norte-Riograndense, or maybe its role in the perpetuation of actions of health centered in the binomial cause/efect. The study was done in the State of Rio Grande do Norte. The data were obtained through public sources gathered in the health secretrary ship of this State. The collected data talks about physiotherapy sections developed by SUS in several areas of the State; such data was collected and analysed after the aproval of Ethic and Resarch Committee of Federal University of Rio Grande do Norte. Concerning the physiotherapy, along with the State Health Secretaryship of the State fo Rio Grande do Norte, there were only records of attending based on cure/rehabillitation, not being observed during the curse of study, any record or action of prevention, promotion and protection towards health. It s possible to notice that there is a highligth to the interventions focusing on the treatment of illness of rheumatic origin and general complaints related to the vertebral column. Such research evidenced that the Physiotherapy in the SUS in the State priorizes the individualized attending centered in the carteziano health/illness model, where the developde actions are turned to the curative and rehabilliting attention, with role fo some or no highligth in the primary attention

Liberdades possíveis em espaços periféricos: escravidão e alforria no termo da vila de Arez (séculos xviii e xix)

This paper discusses aspects of the slavery and emancipations in the village of Arez between the last quarter of the eighteenth century and the first decades of the nineteenth century. It seeks to identify the profile of the slaves and the emancipation possibilities in a peripheral region with few commercial activities, given that the most of the approaches about manumission consider towns and cities where the economic dynamics ware more pronounced, as places of higher possibilities of slaves working in diverse activities that allowed them to accumulate a reserve fund and thus buy their freedom. Therefore it was necessary to raise evidences of slavery in the case study, which was based on surveys of the eighteenth century, and the first decades of the nineteenth century and some population maps and civil records related to the early nineteenth century. The information about the manumission acts were analyzed based on writs of freedom registered in the village of Arez between 1774 and 1827 due to the absence of other documents about it. The registry books include all the documents of the Arez community; so, it was possible to observe what happened in rural localities, in the town, in the headquarters of the district and in the village of Goianinha. Based on information from the documents, it was possible to address some aspects of slavery like the predominant types of groups, the possible activities in which slaves were inserted and the profile of the freed slaves, the emancipation modes and, therefore, discuss the possible relations ship between the colonial space and manumissions and between masters and slaves

Avaliação da fissuração por fadiga em tubos durante transporte marítimo

Tubos de aço são transportados diariamente em todo o mundo, por caminhão, trem ou navio. Conseqüentemente, danos de transporte, podem ocorrer com freqüência e regularidade. O tipo de dano particular selecionado para este estudo foi o de trinca por fadiga, o qual é considerado como um dos mais críticos. Neste trabalho foram estudados tubos de aço fabricados de acordo com os requisitos da norma API 5L [1]. Foram efetuadas caracterizações químicas, mecânicas e metalográficas de um tubo com diâmetro 609,6 mm e espessura 15,87 mm grau X-65. A simulação do transporte por navio de tubos de aço foi feita submetendo-se seções de tubo com comprimento igual a 0,1 metro, a ciclos de fadiga por meio de máquina servo-hidráulica. Foi possível concluir que em tubos soldados, a região adjacente ao cordão de solda é a mais crítica, e que quando o posicionamento do tubo na carga é efetuado de maneira que a solda fique apoiada sobre alguma superfície rígida, a ocorrência de trinca por fadiga torna-se possível principalmente se os procedimentos de manuseio, carregamento e transporte não forem executados da maneira como recomendada pelos fabricantes de tubos e pela norma API [2].

Ballast water: a review of the impact on the world public health

Since the nineteenth century ships have been using ballast water (BW) for safety, stability, propulsion and maneuverability, as well as to redress loss of fuel weight and water consumption, and to maintain structural stress at acceptable levels. Ballast water has been spreading many non-native species around the globe, but little is known about the extent and potential significance of ship-mediated transfer of microorganisms. The global movements of ballast water by ships create a long-distance dispersal mechanism for human pathogens that may be important in the worldwide distribution of microorganisms, as well as for the epidemiology of waterborne diseases. Only a few studies have been carried out on this subject, most of them involving ballast water containing crustacean larvae and phytoplankton. Specialized microbiological studies on these waters are necessary to avoid a repeat of what happened in 1991, when epidemic cholera was reported in Peru and rapidly spread through Latin America and Mexico. In July of 1992, Vibrio cholerae was found in the USA and the Food and Drug Administration (FDA) determined that it came from ballast water of ships whose last port of call was in South America. In Brazil, just a few studies about the subject have been performed. An exploratory study by the Brazilian National Health Surveillance Agency (Agencia Nacional de Vigilancia Sanitaria - ANVISA) found in ballast water different microorganisms, such as fecal coliforms, Escherichia coli, Enterococcus faecalis, Clostridium perfringens, coliphages, Vibrio cholerae O1 and Vibrio cholerae non-O1. Until now, Brazil has been focusing only on organisms transported to its territory from other countries by ballast water, to avoid their establishment and dissemination in Brazilian areas. Studies that can assess the probability that water ballast carries pathogenic microorganisms are extremely important, as is the examination of ships that arrive in the country. Treatment of the human infections caused by BW exists but none is completely safe and efficient.

The invasion of five alien species in the Delta do Parnaiba Environmental Protection Area, Northeastern Brazil

Marine biological invasions have been regarded as one of the major causes of native biodiversity loss, with shipping and aquaculture being the leading contributors for the introductions of alien species in aquatic ecosystems. In the present study, five aquatic alien species (one mollusk, three crustaceans and one fish species) were detected during dives, shore searches and from the fisheries on the coast of the Delta do Parnaiba Environmental Protection Area, in the States of Piaui and Maranhao, Northeastern Brazil. The species were the bicolor purse-oyster Isognomon bicolor, the whiteleg shrimp Litopenaeus vannamei, the giant river prawn Macrobrachium rosenbergii, the Indo-Pacific swimming crab Charybdis hellerii and, the muzzled blenny Omobranchus punctatus. Ballast water (I. bicolor, C. hellerii, and O. punctatus) and aquaculture activities (L. vannamei and M. rosenbergii) in adjacent areas are the most likely vectors of introduction. All exotic species found have potential impact risks to the environment because they are able to compete against native species for resources (food and habitat). Isognomon bicolor share the same habitat and food items with the native bivalve species of mussels and barnacles. Litopenaeus vannamei share the same habitat and food items with the native penaeids such as the pinkspot shrimp Farfantepenaeus brasiliensis, the Southern brown shrimp Farfantepenaeus subtilis, and the Southern white shrimp Litopenaeus schmitti, and in the past few years L. vannamei was responsible for a viral epidemics in the cultivation tanks that could be transmitted to native penaeid shrimps. Charybdis hellerii is also able to cause impacts on the local fisheries as the species can decrease the populations of native portunid crabs which are commercialized in the studied region. Macrobrachium rosenbergii may be sharing natural resources with the Amazon River prawn Macrobrachium amazonicum. Omobranchus punctatus shares habit with the native redlip blenny Ophioblennius atlanticus and other fishes, such as the frillfin goby Bathigobius soporator. Some immediate remedial measures to prevent further introductions from ballast water and shrimp farm ponds should be: (i) to prevent the release of ballast water by ship/vessels in the region; (ii) to reroute all effluent waters from shrimp rearing facilities through an underground or above-ground dry well; (iii) to install adequate sand and gravel filter which will allow passage of water but not livestock; (iv) outdoor shrimp pounds located on floodable land should be diked, and; (v) to promote environmental awareness of those directly involved with ballast water (crews of ship/vessels) and shrimp farms in the region.

Determination of butyltin compounds in surface sediments from the São Paulo State coast (Brazil) by gas chromatography-pulsed flame photometric detection

Occurrence and the effects of butyltin compounds (BTs) have been studied for some years, mainly in countries of the Northern Hemisphere. Due to widespread use of tributyltin compounds (TBTs) and considering their deleterious effects, it is necessary to conduct studies on its occurrence, especially in the marine environment because of its excessive use in coatings of ship hulls to prevent fouling. Moreover, it was important to extend the evaluation to areas where there is no current information about their occurrence. The present work reports the occurrence of BTs in marine sediments of São Paulo state, Brazil. Commercial and leisure harbor sampling sites were selected because these areas are potentially exposed to BTs from antifouling paints used on ship hulls. Analytical conditions for organotin analysis in marine sediments were optimized for GC with pulsed flame photometric detection. Detection limits ranged from 8.4 to 66.3 ng g(-1) using a 610-nm filter, and the linearity range was 20-500 ng g(-1). Concentration levels of BTs were highest in Santos harbor (360 ng g(-1) TBT in average) and Guaruja marina (670 ng g(-1) TBT in average), which seems to be related to intensive boat traffic. Lower levels of BTs were observed in Cananeia, where only fishing boats are present (50 ng g(-1) TBT in average). (C) 2002 Elsevier B.V. B.V. All rights reserved.

Evaluation of a highly sensitive amperometric biosensor with low cholinesterase charge immobilized on a chemically modified carbon paste electrode for trace determination of carbamates in fruit, vegetable and water samples

A highly sensitive amperometric biosensor for determination of carbamate pesticides directly in water, fruit and vegetable samples has been evaluated, electrochemically characterized and optimized. The biosensor strip was fabricated in screen printed technique on a ceramic support using silver-based paste for reference electrode, and platinum-based paste for working and auxiliary electrodes. The working electrode was modified by a layer of carbon paste mixed with cobalt(II) phthalocyanine and acetylcellulose. Cholinesterase (ChE) enzymes with low enzymatic charge were immobilized on this layer. The operational simplicity of the biosensor consists in that a small drop (similar to 50 mu l) of substrate or sample is deposited on a horizontally positioned biosensor strip representing the microelectrochemical cell. The working potential of the biosensor was 370 mV versus Ag/AgI on a ship reference electrode preventing the interference of electroactive species which are oxidable at more positive potentials. The biosensor was applied to investigate the degradation of two reference ChE inhibitors in freeze dried water under different storage conditions and for direct determination of some N-methylcarbamates (NMCs) in fruit and vegetable samples at ppb concentration levels without any sample pretreatment. A comparison of the obtained results for the total carbamate concentration was done against those obtained using HPLC measurements. (C) 1999 Elsevier B.V. B.V. All rights reserved.

Air-sea interaction studies at the station occupied by R/V Sirius

The transfer formulas are used to compute hourly values of sensible and latent heat exchanges for the period July 29 to July 31, 1974. Also, values of eddy shearing stress at the sea surface, Bowen's ratio and dissipation of kinetic energy are computed. The data used cover part of the GATE period for station 20 occupied by the Brazilian Naval Ship R/V Sirius in the Equatorial Atlantic (0730 N 4000 W). The variations in the computed values are studied in relation to rainfall and the synoptic situation. © 1980 D. Reidel Publishing Co.
