The problem of contamination by cadmium and lead in Santo Amaro, Brazil, has been studied since 1970 and the severity of this contamination case has been demonstrated by many authors. This study evaluates the persistence of the superficial soil contamination around the metallurgical plant and attempts to correlate the lead and cadmium concentrations to the past atmospheric emissions from the lead plant and with the presence of lead debris under urban road surface and in the backyards of homes. Past emissions still play an important role in soil contamination. In areas without debris, about 30% of the soil samples had lead concentrations above the agricultural use limit of 180 parts per million (ppm) (according to CONAMA 420, 2009), 20% of the samples had concentrations above 300 ppm (maximum for residential use) and 9.6% of the samples had concentrations above 900 ppm (maximum for industrial use). These concentrations are higher close to the chimney of the metallurgical plant. An average lead concentration of 1316 ppm was found in the backyard samples. About 80% of the houses had lead concentrations above 300 ppm and about 50% of the samples had values above 900 ppm, indicating the importance of the lead debris in the contamination scenario. Although a matter of concern, the cadmium concentrations seem to be less problematic than lead at the present time, probably due to the higher mobility of cadmium. The cadmium concentrations in the atmospheric dispersion and backyard samples showed similar trends, while the influence of the lead debris on the soil contamination is less evident. © 2013 Copyright Taylor and Francis Group, LLC.

Objective: To describe the quality of patients' continuity experiences in a population of outpatients receiving postacute rehabilitation care, and to check which elements and types of continuity most strongly determine their satisfaction with care and functional changes. Design: Cross-sectional self-report survey. Setting: Three postacute ambulatory centers in metropolitan areas. Participants: Outpatients (N=218; mean age ± SD, 38.5±11.7y). Interventions: Not applicable. Main Outcome Measures: The questionnaire included experiences regarding aspects of informational (transference of information, accumulated knowledge), management (consistency and flexibility of care), and relational (established relation and consistency of provider) continuity, as well as questions concerning patients' sociodemographic characteristics, satisfaction with care, and global rating change. Results: Respondents indicated more problems in terms of management and relational continuity than in informational continuity. For all patient groups, experiences regarding elements of management continuity (R2=15.3%-22. 4%), followed by relational continuity (R2=14.3%-25.2%), explained most of the variance of satisfaction. Consistency and flexibility of care, together with an established relation, were the most determining elements of satisfaction. Experiences regarding elements of management continuity explained most of the variance of change (18.5%), and flexibility was the most decisive element. Conclusions: Patient satisfaction and functional changes are related with experiences in aspects of management continuity, where there is room for improvement. Measures of management continuity may be promising as indicators of continuity, and they should be prioritized. © 2013 by the American Congress of Rehabilitation Medicine.

The characteristics of municipal solid waste (MSW) play a key role in many aspects of waste disposal facilities and landfills. Because most of a landfill is made up of MSW, the overall stability of the landfill slopes are governed by the strength parameters and physical properties of the MSW. These parameters are also important in interactions involving the waste body and the landfill structures: cover liner, leachate and gas collection systems. On the other hand, the composition of the waste, which affects the geotechnical behavior of the MSW, is dependent on a variety of factors such as climate, disposal technology, the culture and habits of the local community. It is therefore essential that the design and stability evaluations of landfills in each region be performed based on the local conditions and the geotechnical characteristic of the MSW. The Bandeirantes Landfill, BL, in São Paulo and the Metropolitan Center Landfill, MCL, in Salvador, are among the biggest landfills in Brazil. These two disposal facilities have been used for the development of research involving waste mechanics in recent years. Considerable work has been made in the laboratory and in the field to evaluate parameters such as water and organic contents, composition, permeability, and shear strength. This paper shows and analyzes the results of tests performed on these two landfills. The authors believe that these results could be a good reference for certain aspects and geotechnical properties of MSW materials in countries with similar conditions. © 2010 Elsevier Ltd.

The article aims to present particular views on family farm in economic and social thought, suggesting that this subject has been attracting growing interest in the research communities of these areas in Brazil, at different times. The trajectory seeks to highlight the way in which many authors emphasized, in their analysis, the nature, characteristics and fundaments of family farming. The research methodology is bibliographic and guided by economics and sociology comparative analysis, aiming a contextualized historical reconstruction, concerning theoretical and empirical approaches on family farming. This methodological procedure brought as a hypothesis that Chayanov's theory was seminal for countless approaches, with repercussions into different schools of thought, interested in family farming research. In addition, the research method also permits to conjecture about family farm specificities, to constitute, organize and survive throughout history. The text aims to bring some contribution to the current debate on the role and the importance of family farming in the Brazilian countryside, particularly on its resilience in a scenario of productive concentration and rural depopulation. It also suggests that the quality of this discussion depends on: 1) advances in the conceptual area, 2) more empirical research and 3) new looks on sectorial and regional diversity in Brazil and its influence on family farming varieties and arrangements.

The complexity involved in the collection, treatment and disposal of solid waste; the dimensions of this matter in relation to the various social, governmental, technical and territorial implications, and their potential for qualitative change of the environment require further studies of the management of landfills and their inter-relations with institutions linked to solid waste and the environment. The key question of this paper is: Would the development of a protocol for the installation of solid-waste disposal equipment, involving both environmental and management aspects, suit the specific needs and peculiarities of different municipalities? An explanatory and descriptive multi-case study was used to evaluate the technologies applied in the deployment and management of two landfills in the state of Bahia. A protocol for the management and installation of solid-waste equipment was also designed in this study, based on a theoretical and methodological construction that originated from questions that have also generated news questions and issues, such as how to measure and analyze possible behavioral changes towards sanitation according to the innovative procedures proclaimed throughout the country by the National Solid Waste Policy.

Objective: The present study aimed to identify the elements of the vulnerability of infection for HIV/AIDS among adolescents in an Institution of public education. Methods: It is a descriptive-exploratory study with a qualitative approach, with a random sample of 150 students, using a specifi c questionnaire as an instrument for the collection of information, in order to ensure understanding of adolescents vulnerable to AIDS. Results: After data collection, the tabulations were carried out based on the construction of graphs and/or tables that have helped in the understanding of the results which showed that although the majority of adolescents possess correct knowledge in relation to the prevention and/or transmission of AIDS, it is clear, from the data obtained that there is still a high level of vulnerability of students with respect to this disease, since the attitude on the non-use of condoms is generally favorable among the participants of this research on the susceptibility to the disease. Conclusion: After bibliographical study, data collection and analysis, it is concluded that the adolescents know only vaguely about the dangers of the disease and have limited capacity to assimilate and experience the information they received about it. © 2015, Nucleo de Estudos da Saude do Adolescente.

This study aims to deepen the understanding of the family dynamics of obese only children using a qualitative methodology. Its sample included eight families: four girls and four boys between 7 and 10 years old from high and low social-educational groups, with a nutritional evaluation for obesity:body mass index (BMI) > 97th percentile. The following instruments were applied at their homes: a semi- structured interview, the projective Scenotest and a nutritional evaluation. The analysis was based on the theory of bond configurations (Berenstein and Puget). Its results showed that family dynamics involving contexts of social, cultural and historical nature of the society seem to favor both conditions: child obesity and only child. Social elements emphasizing individualism reflect on the familial and intimate level. The child can face, as soon as he/she is born, conditions for an unsatisfactory basic bond with the mother. The lack of a bond drives the child's satisfaction to food. Besides, the consumer culture interferes with the kind of food that is offered and with the way it is offered, and with the child's social skills; furthermore, it interferes with the decrease in the creation of possible bonds: intrapersonal, interpersonal and transpersonal, in addition to the fact that the child does not have siblings. This study showed that, although not every only child is obese and although not every obese child is an only child, one condition can be a facilitator of the other, as the social, cultural and historical situation of the hypermodern consumer society seems to lead the family to both conditions.

Objective. Relate the case of a child with Duchenne Muscular Dystrophy (DMD) submitted to endurance exercise. Method. Child of the male sex, 6 years, with the medical diagnosis of Muscular Dystrophy, X-linked, of type DMD. The intervention took place in a physiotherapy clinic, totaling 10 consultations with each session lasting 60 minutes. The treatment followed a pattern in which the motivational agent of the procedures was the playing. However, the exercises to fill palm were used with a major emphasis & with the major degree of applicability. For the obtainment of data quantitative have been used: Ceremonious of assessment pre - treatment, Climbs of Vignos modified for Vignos & from measurement from FM at Dynamometer of fill manual. Result. the scale of Vignos haven't altered itself, since the child got maxim punctuation on the 2 appraisals and an amplification significant of the child force of fill palm was perceived: 67,7 % left hand & 33% on the no dominant hand, measured at dynamometer. Conclusion. That takes us to suppose what the proposed treatment didn't speed up the functional wastages, in addition to verify how much the endurance exercise can increase the FM in a patient with DMD.

Objective. To investigate the effects of dual task with cognitive demand on postural control of hemiparetic subjects post stroke. Method. 18 subjects (52.28±13.8 years) with chronic hemiparesis, able to walk with or without gait assistance device. The Timed Up and Go test was used (TUG)- it was requested the individual to rise from a chair, walk three meters, return to the chair and sit down, and the Dynamic Gait Index (DGI) where individuals performed eight tasks involving gait in different sensorial contexts, with and without associated cognitive demand, to assess the balance. Results. It was found that the cognitive demand influenced on the test results, the DGI showed a decrease in score (-3.05) and a time increase on the TUG (2.60) for holding both with a cognitive demand. But there was no difference in reducing the DGI score or increase the TUG time, in the dual task, compared to gender (p=0.860 and p=0.069), educational level (p=0.973 and p=0.571), type of stroke (p=0.408 and p=0.408), and affected hemisphere (p=0.798 and p=0.101). Conclusion. The realization of the dual task by inserting a cognitive demand influences on postural control of hemiparetic subjects post stroke. © 2015 Universidade Federal de Sao Paulo.
