Caracterização da água da microbacia do córrego rico avaliada pelo índice de qualidade de água e de estado trófico

A avaliação do índice de qualidade da água (IQA) e do índice de estado trófico médio (IETm) pode subsidiar a formulação de planos de manejo e gestão de sistemas aquáticos. Neste trabalho, foi avaliada a qualidade da água da microbacia do Córrego Rico, que abastece a cidade de Jaboticabal (SP), utilizando o IQA e IETm. As amostragens de água foram realizadas entre setembro-2007 e agosto-2008, em três pontos: a) em uma das nascentes; b) após a Estação de Tratamento de Esgoto de Monte Alto, e c) na captação de água para abastecimento público de Jaboticabal. As amostras foram analisadas quanto aos parâmetros físicos, químicos e microbiológicos: temperatura, oxigênio dissolvido, pH, DBO5, nitrogênio total, fósforo total, turbidez, resíduo total, ortofosfato, clorofila-a e Escherichia coli. de acordo com os resultados obtidos, concluiu-se que: a) as atividades antrópicas às margens do Córrego Rico reduzem a qualidade de sua água, durante os diferentes períodos do ano; b) os valores médios de IQA nos três pontos analisados apresentaram relação direta com os valores médios de IETm, porém ocorreu maior discriminação da qualidade da água pelo IETm, identificando diferentes graus de trofia para os pontos e períodos de amostragens; c) o IQA apresentou melhor diferenciação da qualidade da água entre pontos no período seco e o IETm diferenciou melhor no período chuvoso; d) o processo de autodepuração e/ou a confluência do Córrego Tijuco com o Córrego Rico contribuem para melhor qualidade da água, tornando-a adequada ao abastecimento urbano após tratamento convencional.

Protagonismo silencioso: a presença da OPAS na formação de recursos humanos em saúde no Brasil

The aim of this study is to assess the contribution of the Pan American Health Organization (PAHO) to the field of human resources for health in Brazil. The assumption is that this organization not only influenced the development of this field, but but that it was also influenced by Brazilian institutions and by national political movements, through the interaction of its consultants with these movements. Four projects were selected, through which the contribution of PAHO was evaluated: the Program for the Strategic Preparation of Health Personnel (PPREPS), the Project for the Large Scale Formation of Middle and Low Level Personnel (Large Scale Project), the Project for Qualification in the Development of Human Resources in Health (CADRHU) and the Project for the Managerial Development of Basic Units of the National Health System (GERUS). To operacionalize the study, we used three basic complementary procedures: a bibliographic research, documental research and an interview. The time frame considered was from 1975, the year an agreement was signed between PAHO, the Ministry of Health and the Ministry of Education and Culture, establishing PPREPS. It was through this program that the first PAHO team of national human resource consultants was contracted. The period between 1975 and 1999 was marked by political and social movements that changed the course of health in the country; among these was the Movement of Sanitary Reform in Brazil, which culminated in the implementation of the National Health System (SUS). This paper shows the connections of the PAHO consultants with this movement and the implications that this had for the Program of Cooperation in the Development of Human Resources of PAHO/Brazil. It also demonstrates that as the program became contaminated by national movements of health system reorganization and of democratization of Brazilian society, it proposed, in cooperation with national institutions, an organization of determinate areas of operation of these same institutions. The manuscript further reveals that, with the Large Scale Project, the human resources program determined the pedagogical and methodological option that would be the model for various other educational projects undertaken by a number of Brazilian institutions with the technical cooperation of PAHO. And finally, the repercussions and contributions of these projects, which strengthened the the field of human resources in the public health services of the country, are identified. Data analysis was based mainly on the theories of Bourdieu, Gramsci and Freire

Trânsito de saberes e campo representacional na visão dos profissionais da saúde da família e do programa de educação pelo trabalho e para a saúde

The Family Health Strategy (ESF) is emerging as a possible restructuring of services and new practices of intervention in health care; it requires skilled professionals to work with that framework. Within this purpose, we established the Education Programme for Work and Health (PET-Saúde), in order to integrate teaching and service activities, focusing on primary care. On this basis, the aim of this work is to apprehend the social representation of nurse, doctor and dentist (Project PET-Natal Health RN preceptors) on the ESF, while practice field of them. It is a descriptive and exploratory study, with a qualitative approach, carried out in 07 Family Health Units (USF) included in the PET-Saúde Natal (RN). The population was composed of 35 professional components of the primary care team with bachelor's degree of the USF linked to this project. The sample was composed of 05 nurses, 05 physicians and 05 dentists, for a total of 15 subjects. Data were collected through three instruments: the drawing-themed story, a semi-structured individual interviews and field diary. The data relating to the identification of the subjects were entered and tabulated by the Microsoft Excel software 2007 version. The drawing analysis and interpretation is given by the significance attributed to the resource chart from title and keywords assigned by the subjects, considering the ESF as an inductive term. The stories and interviews were transcribed and typed and then subjected to read/listen the material and a lexical analysis through Alceste. After this process, the discursive material was analyzed and discussed by theoretical and methodological feature of the Social Representations theory. The majority of health professionals were female, aged between 46 and 52 years old, married, income less than six minimum wage, time since graduation ranged from 22 to 29 years and working time in the ESF range from 02 to 11 years. From the classification system ALCESTE were selected categories identified by: Category 1 - ESF: relations and territory; Category 2 - Training and bond profile; Category 3 - Working process in the ESF; Category 4 - Articulation between teaching and service; Category 5 - Health care and disease prevention. The representational field construction, while a process, followed the logic of structural cores in existing categories. In this sense, it is clear that the ESF is an environment rich in diversity, experience and relationships with potential such as the relationship "very subject-subject" and the link established between professional-community, but also has some weaknesses such as poor working conditions, lack of popular participation and management support, thus difficulties in the achievement of teamwork. Being essential to that end, the teaching-service aimed at the formation of a new health professional able to work in the ESF. In this research, the training of the representational field encountered a diversity of structural cores, or thoughts on training, about the ESF because of the greater emphasis on the here and now of the interaction between health professionals, the ESF, the community, PET Health-UFRN and students, emphasizing that such proposals are still considered as concepts in the context of recent health and that, therefore, are not fully realized in the social imaginary

Adubação com nitrogênio e potássio em mudas de goiabeira em viveiro comercial

The fertilization takes key role at the production of fruit seedlings in order to ensure a good development and early production. The aim of this study was to evaluate the effects of nitrogen and potassium on the growth of guava seedlings. Herbaceous stakes of guava, Paluma cultivar, were rooted in a mist room, in polyethylene bags containing substrate. The experiment was conducted in a commercial nursery, in randomized blocks and a factorial scheme 4x4, with four doses of nitrogen (0, 552, 828 and 1104 mg dm(-3)) and four doses of potassium (0, 726, 1,089 and 1,452 mg dm(-3)) in three replications and three plants for parcel. During the filling of the bags (1,5 dm(-3)), were added 100 mg dm(-3) of superphosphate, while fertilizers containing nitrogen and potassium were split into three times. After 120 days, the seedlings were evaluated. There was a significant effect of nitrogen in the variables height, stem diameter, number of leaves, SPAD index, dry weight of leaves, stems, total, Dickson quality index, and nitrogen accumulation. The fertilization with potassium did not influence the biometric parameters, SPAD index and Dickson quality index.

Seedlings production of Tabebuia heptaphylla in different substrates and levels of irrigation, in greenhouse conditions

The objective of this research was to evaluate the growth of Tabebuia heptaphylla seedlings in distinct substrates with different amounts of urban waste compost and the relation between this growth and irrigation. A completely randomized experimental design was used, with a factorial arrangement of 15 substrates and 2 irrigation levels. The substrates were composed by the combination of different materials: urban waste, tanned cattle manure, vermiculite, soil and the commercial form Plantmax (R). For the study of the seedlings development, the following characteristics were evaluated: plant height, stem diameter at soil level, number of leaves, above ground dry matter, root system dry matter, relation between plant height and stem base diameter, Dickson quality index and relation between plant height and above ground dry matter. Evaluations of plant height, stem diameter at soil level and number of leaves were made at 75, 90, 105, 120, 135 and 150 days after sowing. According to the results, it was concluded that urban waste compost does not increase plant development. Significant differences in relation to the irrigation levels were found, with better results for the 150% irrigation level compared to 100% evapotranspiration.

Análise da situação de trabalho do motorista em uma empresa de ônibus urbano da idade de Natal (RN)

The problem dealt with in this study concerns the analysis of bus drivers' working situation. It stemmed from the need to identify the difficulties faced by these professionals in accomplishing the results expected by the company. A case study was carried out in a public transportation company in the city of Natal. Records and observations made in the workplace, alongside perfomance indicators, such as absenteeism tax, staff turnover and traffic accidents, revealed problems in their activity. It was made clear that, in the company being studied, absenteeism was related to health problems, particularly psychiatric and musculoskeletal disorders, and that although the indicators of traffic accidents and staff turnover have declined over the years, they are still elevated. The interviews involved 50 of the 124 drivers who worked directly in the service, and contained questions covering eleven factors related to the drivers' work. They indicated a gap between the prescribed work and the work actually done, in that there were a series of embarassing or stressful situations involving traffic, itinerary length, road conditions, vehicle maintenance, physical environment (bus terminus), job post and supervision policies. On the other hand, factors such as enjoying driving, the work itself and being with workmates positively influenced the drivers' working conditions. In the propositions of the administration and human resources subsystems, some alternatives were found in order to remodel this activity

Análise comparativa dos métodos de fatores ponderados na seleção de áreas para aterros sanitários

This study presents a comparative analysis of methodologies about weighted factors considered in the selection of areas for deployment of Sanitary Landfills, applying the methodologies of classification criteria with scoring bands Gomes, Coelho, Erba & Veronez (2000); Waquil et al, 2000. That means, we have the Scoring System used by Union of Municipalities of Bahia and the Quality Index Landfill Waste (IQR) which are applyed for this study in Massaranduba Sanitary Landfill located in the municipality of Ceará Mirim /RN, northeastern of Brazil. The study was conducted in order to classify the methodologies and to give support for future studies on environmental management segment, with main goal to propose suited methodologies which allow safety and rigor during the selection, deployment and management of sanitary landfill, in the Brazilian municipalities, in order to help them in the process to extinction of their dumps, in according of Brazilian Nacional Plan of Solid Waste. During this investigation we have studied the characteristics of the site as morphological, hydrogeological, environmental and socio-economic to permit the installation. We consider important to mention the need of deployment from Rio Grande do Norte State Secretary of Environment and Water (SEMARH), Institute of Sustainable Development and Environment of RN (IDEMA), as well, from Federal and Municipal Governments a public policies for the integrated management of urban solid waste that address environmental preservation and improvement of health conditions of the population of the Rio Grande do Norte

Qualidade da silagem de grão úmido em função da temperatura ambiente e pressão interna de armazenagem

Visando estabelecer a contribuição dos parâmetros físicos na qualidade final da silagem de grãos úmidos de milho, foi conduzido experimento, no interior de câmara climatizada, simulando cinco condições de temperatura ambiente (5ºC 24h-1 por dia; 25ºC 24h-1 por dia; 40ºC 24h-1 por dia; 20ºC 16h-1 por dia + 5ºC 8h-1 por dia; 30ºC 16h-1 por dia + 20ºC 8h-1 por dia) e duas condições de pressão no interior dos tambores de armazenagem (com e sem pressão interna). Para se determinar os efeitos sobre o grau de disponibilidade do amido na silagem pronta, procedeu-se a análises para avaliar a qualidade final da silagem (teor de umidade, pH, ácidos orgânicos, amido total e granulometria). O delineamento estatístico utilizado foi o inteiramente ao acaso, num fatorial 5 x 2, com três repetições. Os resultados obtidos indicaram influência significativa tanto da temperatura quanto da pressão, sendo os efeitos mais benéficos verificados nos tratamentos '30ºC 16h-1 por dia + 20ºC 8h-1 por dia', '25ºC 24h-1 por dia' e 'ausência de pressão'.

Limonologia e qualidade ambiental de um corpo lêntico receptor de efluentes tratados da indústria de petróleo

Environmental pollution has become a subject of public interest throughout the world. Not only have developed countries been affected by environmental problems but also the developing nations have started to suffer from the serious impacts of pollution. Within this context it is necessary to collect simplified environmental data to assist in the management of water resources by the appropriate authorities. These data are obtained through an environmental index that allows a space-time comparison of points distributed in the same aquatic body, or between different water bodies, for physico-chemical and bacteriological parameters. The aim of this present study was to determine the environmental status of the Lagoa de Baixo at Guamaré/RN, where a production unit of PETROBRAS RN/CE is located. For this purpose the Water Quality Index (WQI) was used in both an add and multiply form, the Trophic State Index (TSI) and the Environmental Quality Quotient (EQQ), as well as determining the concentrations of metals. The average values obtained for the WQI, in its two forms were 68,67 and 62,76 respectively which were inside the good qualification. According to the TSI the lagoon showed characteristics of a middle trophic state, and an impact level of regular as determined by the EQQ

Qualidade de mudas clonais de Eucalyptus urophylla x E. grandis em função do substrato

Considering the increasing demand for seedlings of plants for aforestation and the scarcity of raw materials for the substrates used for plant growth, it is necessary to evaluate new components and formulations that ensure the quality of seedlings. In this experiment the development and quality of production of Eucalyptus urophylla x E. grandis seedlings was studied through vegetative propagation, as a function of nine compositions of substrate, produced from fine-grained vermiculite, carbonized rice chaff and coconut fiber in hard plastic tubes of 50 mL as containers. The physical properties of substrates and morphological development and the quality of the root system of seedlings were evaluated at 90 days after staking. The substrates with higher total porosity promotes better quality of the root system, which consequently results in cuttings with larger diameter, shoot and root dry weight and Dickson Quality Index. Other properties for the physical characteristics of substrates other than mentioned in literature can also be considered adequate.

Influência das águas da Bacia Hidrográfica Pirangi na balneabilidade das praias de Pirangi, nos municípios de Nísia Floresta e Parnamirim Rio Grande do Norte, Brasil

The Pirangi beach is located in the eastern coastline of Rio Grande do Norte state, in the municipality of Parnamirim and Nísia Floresta. In it flow into Pirangi Watershed (PW), whose water receives large amounts of pollutants, mainly domestic and industrial sewage from districts where pass the rivers that consist it, compromising, thus, the bathing water quality of the Pirangi beach. Bearing in mind the importance of water sanitary quality to ensure an environment that no present risk to the bathers s health, this work had as main objective to assess the influence of the PW s waters in the bathing water quality of the Pirangi beaches. To that end, were made collections of water in the beaches and in the rivers with the intention of quantify the fecal contamination indicators thermotolerant coliforms and enterococci, to then classify the conditions of bathing water quality according with the CONAMA Resolution number 274 of 2000. For the purposes greater knowledge about the health conditions of the Beaches Pirangi and about the influence the PW s waters exert on it, was done parallely to the study of the water quality, an investigation of the sand sanitary quality. Furthermore, it was made an evaluation of the PW s Water Quality through Water Quality Index (WQI). Starting from the results obtained in the research present was possible to verify, among other aspects, that the entry of the PW s waters in the Pirangi beaches exerts direct influence in the bathing water quality of the same ones, being the North Pirangi beach (point tracking PA-02) the most influenced. There was noticed also a significant reduction in the conditions of bathing water quality of the beaches in the rainy season. However, the precariousness do sewerage system of the Natal metropolitan region and the absence of a right system of treatment an final disposal of domestic sewage and industrial are the main factors responsi le for deterioration of the PW s Water Quality, and as a consequence, compromising the bathing water quality of the Pirangi beaches

Funcionalidade em pacientes após acidente vascular encefálico: relação com o sono e ritmo de atividade-repouso

It is known that sleep plays an important role in the process of motor learning. Recent studies have shown that the presence of sleep between training a motor task and retention test promotes a learning task so than the presence of only awake between training and testing. These findings also have been reported in stroke patients, however, there are few studies that investigate the results of this relationship on the functionality itself in this population. The objective of this study was to evaluate the relationship between functionality and sleep in patients in the chronic stage of stroke. A cross-sectional observational study was conducted. The sample was composed of 30 stroke individuals in chronic phase, between 6 and 60 months after injury and aged between 55 and 75 years. The volunteers were initially evaluated for clinical data of disease and personal history, severity of stroke, through the National Institute of Health Stroke Scale, and mental status, the Mini-Mental State Examination. Sleep assessment tools were Pittsburgh Sleep Quality Index, the Questionnaire of Horne and Ostberg, Epworth Sleepiness Scale, the Berlin questionnaire and actigraphy, which measures were: real time of sleep, waking after sleep onset, percentage of waking after sleep onset, sleep efficiency, sleep latency, sleep fragmentation index, mean activity score. Other actigraphy measures were intraday variability, stability interdiária, a 5-hour period with minimum level of activity (L5) and 10-hour period with maximum activity (M10), obtained to evaluate the activity-rest rhythm. The Functional Independence Measure (FIM) and the Berg Balance Scale (BBS) were the instruments used to evaluate the functional status of participants. The Spearman correlation coefficient and comparison tests (Student's t and Mann-Whitney) were used to analyze the relationship of sleep assessment tools and rest-activity rhythm to measures of functional assessment. The SPSS 16.0 was used for analysis, adopting a significance level of 5%. The main results observed were a negative correlation between sleepiness and balance and a negative correlation between the level of activity (M10) and sleep fragmentation. No measurement of sleep or rhythm was associated with functional independence measure. These findings suggest that there may be an association between sleepiness and xii balance in patients in the chronic stage of stroke, and that obtaining a higher level of activity may be associated with a better sleep pattern and rhythm more stable and less fragmented. Future studies should evaluate the cause-effect relationship between these parameters

Sono e síndrome da fragilidade em idosos residentes em instituições de longa permanência

Introduction: The aging process causes quantitative and qualitative changes in sleeping. Such changes affects more than half of the adults above 65 years old, that live in the community and 70% of the institutionalized, a great negative impact in their quality of life. One of the pathological displays of aging, that share some characteristics with sleeping disorders and predict similar results, is the Frailty Syndrome, that characterize the most weakened and vulnerable elderly. The way sleeping disorders play a role in the frailty pathogeneses remains uncertain. Objective: Evaluate the relation between the sleeping and the frailty syndrome on institutionalized elderly. Methodology: A transversal study was performed with 69 elderly in institutions in the city of João Pessoa PB. Were used the Pittsburgh Sleeping Quality Index and actigraphy to subjective and objective variables, respectively, and questionnaires and specific tests to frailty phenotype variant (Fried Frailty Criteria). In the statistic analysis were used the Pearson correlation test, Chi Square and One-way ANOVA test, with Tukey-Krammer posttest. Subsequently, a Simple Linear Regression model was built. On every statistical analysis were considered a confidence interval of 95% and a p < 0,05. Results: The sample was characterized by the prevalence of the frail (49,3%), women (62,3%), single (50,7%) and 77,52 (±7,82).The frail elderly obtained the worst sleeping quality 10,37 (±4,31) (f = 4,15, p = 0,02), when compared with the non-frail. The sleep latency influenced more the frailty (R2 = 0,13, β standard = 1,76, β = 0,41, p = 0,001). Weren t found differences between the standard resting-activity variable and the frailty phenotype categories. Conclusion: Sleeping alterations, including bad sleeping quality, prolonged sleep latency, low sleep efficiency and day drowsiness, influenced the frailty in institutionalized elderly

Qualidade subjetiva do sono e queixa de insônia em pacientes com Acidente Vascular Cerebral

Brain injury can be associated with changes in the sleep-wake cycle. However, studies about sleep disturbances and their relationship with quality of sleep are scarce. Besides, it remains to be known how stroke affects the mechanisms of sleep. The aim of this study was to investigate quality of sleep, complaints of sleep disturbances and associated factors in stroke patients from the Physical Therapy services in Natal -RN. This was a cross-sectional descriptive study involving 70 individuals (aged 45-65 years), 40 patients (57 ± 7 years), 11 ± 9 months after injury, and 30 healthy individua ls (52 ± 6 years), evaluated with the Pittsburgh Sleep Quality Index (PSQI) and Sleep Habits Questionnaire. The data were analyzed by Chi-square test, t Student test and logistic regression. Poor quality sleep was found in 57,5% of the patients (6,3 ± 3,5) and was significantly higher than in the control population (3,9 ± 2,2) (t Student test, p=0,002). The patients showed significantly higher value of PSQI than controls: sleep latency (p=0,019), length of sleep (p=0,039) and dysfunction during the day (p=0,001). Regarding complaints of sleep disturbances (dyssomnias and parasomnias) analyzed by Chi-square test, the complaint of insomnia was the most prevalent (patients: 37,5%; healthy subjects: 6,7%; p=0,007). Regression analysis showed that sl eep latency (p=0,036) and complaint of insomnia (p=0,036) were associated with quality sleep. In addition, female gender (p=0,036) and complaint of broken sleep (p=0,003) were considered risk factors for the presence of insomnia. Our results show that stroke affects the homeostatic process of sleep. Shorter sleep latency and the absence of insomnia are considered protective factors for good sleep quality and this should be taken into consideration in the diagnostic and therapeutic strategies

Trajetória de carreira do profissional de recursos humanos

The idea that the career consists in a linear path throughout the individual s professional life structured by the company where he or she works has been changing to a new reality in which the career is seen as a journey, open to possibilities and uncertainties. Several models have come up as an attempt to comprehend and analyze this journey. Among them, there is the model of career narrative, which assumes that, while narrating, individuals give meaning to their own path, and at the same time they consider personal factors and the environment that act on their professional biography. This paper aimed to explore and articulate issues related to the environment and career paths of the human resource professionals working in the Greater Natal. For this purpose, the model of career narrative was used. From the methodological viewpoint, the project was divided in two stages. The first was characterized by conducting a survey with the intention of mapping professionals socio-occupational characteristics, through the application of a semi-structured questionnaire. The data was analyzed by descriptive statistical techniques and cluster analysis. The descriptive statistical analyses included 117 participants. The results indicated that HR professionals of Greater Natal have different functions, develop activities focused on different subsystems, have an increasing career path, and focus their professional formation in Business Administration and Psychology. The second stage of the study was characterized by the use of 17 narrative interviews, whose participants, in the process of nonprobabilistic sampling, were identified based on their belonging to the three clusters: Group 1, HR and public administration; Group 2, HR experts; and Group 3, HR beginners. Analyzing the results of the qualitative phase, it was found that the identification with the activity practiced is a deciding factor for choosing and remaining in the HR field. The lack of professional recognition appears as the main difficulty faced by professionals, as well as the lack of employment opportunity in the Greater Natal. The results analysis leads to a series of discussions on the career path in HR and reflections for this professional category, its representative bodies and educational institutions
