Sono e percepção visuoespacial em trabalhadores de uma empresa petroquímica submetidos a esquemas de trabalho em turnos alternantes

Shift work consists of an array of unusual work hours, such as evenings and weekends, and increasing workload, in order to meet the uninterrupted production, which leads to changes in the quality, duration and regularity of sleep. Research indicates that sleep alteration cause cognitive processes to become slower, unstable and prone to errors, leading to loss of cognitive functions such as visuospatial perception. In this sense, this research aimed to evaluate sleep quality and its relation to visuospatial perception in workers in alternating shifts. Participants were 21 panel operators in a petrochemical company, male, aged 19-53 years. All participants were subjected to schedules of alternating shifts (day and night) of 12 nonstop hours and data were collected from 10 workers who were assigned to the day shift and 11 workers assigned to the night shift. For the sleep evaluation were used the Sleep Diary, the Sleep Habits Questionnaire, the Chronotype Identification Questionnaire and the Pittsburgh Sleep Quality Index (PSQI). The visuospatial skills were assessed using the Rey Complex Figure Test and attention was assessed using a portable version of the Psychomotor Vigilance Task (PVT). The results showed that the general sample of workers obtained poor sleep quality on working days and good sleep quality during the work break. There was shortened sleep duration in the work week and appropriate duration in the work break. No losses were found in the workers visuospatiality, but the good quality of sleep during the work break was correlated to adequate visuospatial performance, for the day shift workers. The attention performance oscillated throughout the work hours, especially on the night shift. It is concluded that the alternating shifts work scheme can be detrimental to the sleep quality workers and a good sleep quality can contribute to a better visuospatial performance

Diagnóstico ambiental das águas do estuário Jundiaí-Potengi pela determinação dos índices de qualidade da água e toxidez

This study is an environmental diagnosis of the Jundiaí-Potengi/RN estuarine system waters, using calculations of pollution indicator indices such as the Water Quality Index (WQI) and the Toxicity Index (TI). The samples were collected at twelve points on the estuary, at high and low tide, between August and November 2007, over four campaigns. The study area, located in a high impact region, has various activities on its banks such as: discharge of untreated or undertreated domestic and industrial sewage, shrimp farming, immunizer stabilization lakes, riverside communities, etc. All the parameters analyzed were compared to the limits of CONAMA Resolution No. 357 of 2005 for healthy and saline Class 1 waters. The results found prove the impact caused by various activities, mainly the parameters related to the presence of organic material, such as DQO, DBO, COT and thermotolerant colliforms. The IQA for most of the collection points was of medium quality. For the metals, although values above the Resolution limits were found, most of them were lower than the detection limits of ICP-OES used, indicating that they tend to be transported by the dynamic of the tides or rainfall and are deposited in bottom sediments, resulting in a TI of 1.0 in this water, when they are absent, which occurs in most cases, or 0.0, when heavy metals are found in these waters

Monitoramento das águas da bacia hidrográfica pirangi pela determinação dos índices de qualidade da água-iqa e índice de toxidez-it

The problems of water supply in Northeast Brazil are severe and require more focused studies. This work was intended to assess water quality in the watershed Pirangi, located in the Northeastern state of the newborn using the Water Quality Index, AQI associated with the Index of Toxicity-IT. The data presented in this study were collected in November 2008, June 2009 and March 2010 at eight sampling stations distributed throughout the basin. The study covered nine parameters, based on guidelines established by CETESB, and seven members of Metal Toxicity index-IT. These waters are framed in the classification between GOOD and BAD showing AQI 41.34 minimum and a maximum of 76.23. Virtually all seven metals analyzed were below the detection limits of ICP-OES giving IT a water equal to one when they are absent and 0 when there are levels of trace metals

Gestão por Competências em Organizações Públicas: O Processo de Transformação Organizacional e seus Impactos Junto aos Servidores na Secretaria Estadual de Administração e Recursos Humanos (SEARH/RN)

The state has changed over time in order to meet a society with increasingly stringent demands. Techniques of private means begin to be employed in an attempt to overcome the dysfunctions entrenched bureaucracy, making the machine faster. By federal law by the People Management Skills was established as a reference for the administration of Human Resources of the public sector in an attempt to develop professionally servers, based mainly on the three pillars of the model: the knowledge, skills and attitudes. This thesis aims at understanding, in the view of employees, the perceived impacts on the organizational changes occurring in the Department of Administration and Human Resources of the State of Rio Grande do Norte in order to implement a People Management Skills-based. It is a simple case study, characterized by the research during a certain period of time, collecting data in a real environment of an organization, in this case SEARH/RN. The procedures used in collecting data were the literature review, documental research and field research. We used a qualitative approach with exploratory and descriptive approach. Every reform was implemented in the institution and reported from there analyzed the impacts observed by the servers. As a result we observed a considerable advance in institutional activities, mainly relating to physical structure / organizational and human resource policies, with minor advances on labor policies, in much the result of the guiding focus of the reform on SEARH/RN. The impacts in total were more positive than negative and direct paths to improvement in public organizations. Making a general analysis of the modernization program implemented in SEARH/RN, we can conclude that there was a distinct change in all dimensions studied, mostly pointing out positive aspects, and contrary to the opinion of some authors, who claim to be very difficult to implement reforms in public organizations, since they are highly institutionalized environments. What was found was a big organization, with gaps and weaknesses, but with a much larger number of hits and recognition from institutional actors

Ambiente institucional e desempenho diferenciado na agropecuária norte-rio-grandense: quais as relações?

MÉTODOS: Inquérito sobre o impacto na qualidade de vida infligido pela urticária crônica a partir do questionário DLQI validado para a língua portuguesa. Pacientes foram entrevistados durante suas consultas em ambulatório especializado, entre maio de 2009 e maio de 2010, em serviço público brasileiro (Botucatu-SP). Os escores do DLQI foram analisados segundo subgrupos: idade, gênero, escolaridade, tempo de doença e presença de angioedema. RESULTADOS: Foram entrevistados 100 pacientes com urticária crônica. Predominou o gênero feminino (86%), a idade média foi de 41,8 anos, duração média da doença foi de seis anos e angioedema ocorreu em 82% dos pacientes. O escore médio do DLQI foi de 13,5, caracterizando grave impacto à qualidade de vida, superior a hanseníase, psoríase, eczema atópico e carcinoma basocelular. Presença de angioedema se associou a maiores escores: 14,5 x 9,9 (p < 0,01). Pacientes do gênero feminino referiram maior impacto quanto ao vestuário, já o gênero masculino referiu quanto ao tratamento, trabalho e estudo (p < 0,05). CONCLUSÃO: Urticária crônica inflige grave comprometimento da qualidade de vida nos pacientes avaliados em serviço universitário brasileiro, especialmente nos portadores de angioedema.

As praças públicas de Natal/RN no âmbito dos problemas socioambientais urbanos

This paper presents the public square as a subsystem of the city for the potential integration of elements 'natural' and built environment. But sometimes the suitability of projects and the social processes involved are not compatible and favorable to their real functions in urban space. The city of Natal, with a population of 803,739 inhabitants has 253 public parks not uniformly distributed in the urban area, but mostly in central areas and their absence in some peripheral neighborhoods. In this sense, the objective of this paper is to analyze the quality and spatiality of the city's public squares within the urban socio-environmental problems. For this, use of simple random sampling to define the sample and the proportional allocation of districts, totaling 168 squares to be raised. We prepared a form to collect data on the field that includes aspects of leisure, infrastructure and environment. For each square sampled was calculated Square Quality Index (PQI), then calculating the average per IQP neighborhood. The rates found were crossed with census data and Municipal Public Administration by neighborhood, using multivariate analysis. We generated maps, charts and tables, considered appropriate to each question format, focused comparison. The public square appears as an indicator of environmental challenges present in intra-urban spaces of the city. Their spatial distribution is not consistent demand population, both by disposition and by how much. In terms of quality are characterized by different levels of inadequacy and degradation aspects of leisure, environmental and infrastructure, often causing disfigurement, abandonment and improper occupation in such spaces. Multivariate analysis point to a central concentration and their problems in certain administrative units, not only as regards the public squares, but also to aspects of education, income, and other violence, perpetuating the problem. The various levels of inadequacy and degradation of public squares have been more blatant in the poorest neighborhoods of the city, pointing to a structural pattern associated with the intrinsic characteristics of the neighborhood and the socioeconomic profile of the local population. These are problems of social and environmental dimensions, threaded in and influenced the political, economic and broader social process of transformation of the city and the urban. Based on an uneven process in which space necessarily reflect the contradictions inherent in the active forces and interests. Thus evidencing the importance of managing the necessary public effectively engaged with the problems that are present there, in order to equate them, without being prioritized certain areas of the city at the expense of others

Thermal behavior of residues (sludge) originated from Araraquara water and sewage treatment station

The number of the cities with canalized water and sewage treatment stations has increased lately and consequently having in mind the great concern on environment preservation and the quality of the water used by society. However, these stations are nowadays causing another kind of problem: a huge quantity of sludge as residue. Due to the implication of the residue on the environment and, consequently, to human life quality, performing of an accurate investigation about the components of such sludge, as well as the thermal stability of this residue in the environment become necessary. This paper presents a study on sludge from water and sewage treatment station, as well as the thermal characterization of residue. Such study was performed through FTIR, atomic absorption, thermoanalytical (TG/DTG, DTA) techniques, that made it possible to observe that the main components of the sludge are clay, carbonates and organic substance, presenting a low rate of metals and a unique thermal behavior since the sludge from the treatment station has a higher thermal stability.

Relações da atividade agropecuária com parâmetros físicos químicos da água

Water Quality Index (WQI) was used during summer and winter of 1994 and 1995 in the final section of Onça and Feijão streams, downstream Broa Reservoir (São Carlos/SP) to evaluate agricultural and catlleman effects. In Onça stream water quality was acceptable in winter and inappropriate to conventional treatment in the summer. In Feijão stream the water had an excellent quality in winter and good in the summer. A MANOVA (Multivariate Analysis of Variance) has used to discriminate seasons and streams. Correlation (p<0,05) among the variables was tested. Water temperature, turbidity, pH and fecal bacteria are highly correlated and can be one of the factors that cause WQI change by seasons.

Padrão de qualidade de mudas de Trema micrantha (L.) Blume, produzidas sob diferentes períodos de sombreamento

O objetivo deste trabalho foi verificar a influência do período de permanência das mudas sob sombreamento nos parâmetros empregados na avaliação da qualidade das mudas de Tremamicrantha (crindiúva). O delineamento experimental foi o inteiramente casualizado, com quatro repetições por tratamento, contendo 88 plantas cada. Foram realizadas três avaliações, aos 90, 120 e 150 dias após a emergência. Os tratamentos na avaliação I foram 45, 60, 75 e 90; na avaliação II, 45, 60, 75, 90, 105 e 120; e na avaliação III, 45, 60, 75, 90, 105, 120, 135 e 150 dias de permanência sob sombreamento com 48% de retenção da radiação, respectivamente. Foram avaliados os parâmetros morfológicos das mudas, suas relações e o índice de qualidade de Dickson. As mudas desenvolvidas sob maiores períodos de sombreamento, embora tenham alcançado maiores alturas das partes aéreas e áreas foliares, apresentaram as piores qualidades, com redução do diâmetro do coleto, da massa seca do sistema radicular e do índice de qualidade de Dickson e aumento da relação altura da parte aérea/diâmetro do coleto e da relação parte aérea/sistema radicular. Nas três avaliações, o período de permanência das mudas sob sombreamento não influenciou significativamente os parâmetros área foliar, massa seca das folhas, massa seca da parte aérea e massa seca total. As mudas apresentaram melhores padrões de qualidade e condições de plantio no campo a partir dos 120 dias de idade, quando crescidas sob 45 e 60 dias de sombreamento. O índice de qualidade de Dickson foi bom indicador do padrão de qualidade das mudas.

Condições e relações de trabalho no serviço público: o caso do governo Lula

Cet article a l'objectif de détailler les diverses initiatives du gouvernement Lula (2003-2010) par rapport à la mise en forme d'une politique de ressources humaines et, de cette façon, vérifier s'il y a eu une amélioration des conditions et relations de travail dans le secteur public brésilien. À partir des années 1990, et dans le sens contraire de la grande croissance de l'emploi public dans les six décennies précédentes, l'adhésion des gouvernements brésiliens aux principes du « Consensus de Washington » souligne le fonctionnalisme comme point fondamental dans l'agenda des réformes nécessaires à la reprise de la croissance économique. Ces gouvernements là se sont penchés sur le traitement de l'emploi public comme étant un problème fiscal et ont agi pour restreindre sa dimension. Simultanément, les conditions et relations de travail se sont présentées plus fragilisées (rendues évidentes par l'absence de réajustement de salaire; la croissance de formes variables de rémunération ; l'élargissement du cadre de travailleurs temporaires et externes, e avec l'attitude autoritaire devant la représentation syndicale). Avec une recherche documentaire et bibliographique, on pourra remarquer que la restructuration de nombreuses carrières, la reprise des concours, la création de la « Réunion Nationale de Négotiation Permanente », la réforme de la sécurité sociale et les réajustements selectifs des rémunérations manifestent l'ambiguïté comme une marque fondamentale des politiques de ressources humaines. Cela parce que, au même temps, les progrès des conditions de travail du serviteur public ont toujours été accompagnés par l'entretien d'une partie de l'agenda conservatrice des années 1990, surtout par rapport à la reproduction de limites fiscaux rigoureux.

Gestão de recursos humanos e desempenho operacional: evidências empíricas

A gestão de recursos humanos é frequentemente apontada como uma variável que influencia positivamente no desempenho das organizações. Enquanto argumentos e proposições teóricas de teor similar se multiplicam na literatura especializada, ainda são raras as pesquisas que lançam luzes sobre essa relação para empresas brasileiras. Nesse sentido, foi realizada uma pesquisa com o objetivo de verificar, empiricamente, se a gestão de recursos humanos influencia de maneira positiva o desempenho de empresas do segmento de autopeças e componentes automotivos em suas operações. Metodologicamente, realizou-se um survey com 75 empresas do setor mencionado, cujos dados foram analisados por meio de modelagem de equações estruturais, uma análise multivariada de segunda geração. A principal hipótese da pesquisa foi confirmada, revelando que, de fato, a gestão de recursos humanos está positivamente relacionada com o desempenho operacional das empresas analisadas.
