A Fibrose Cística é uma doença crônica que grande impacto exerce sobre a vida familiar. A experiência da doença é a maneira pela qual os indivíduos respondem à doença, atribuindo significados e buscando maneiras para lidar com ela no seu cotidiano. O estudo teve como objetivo compreender a experiência da Fibrose Cística a partir do contexto familiar. Estudo de caso etnográfico, realizado com famílias de crianças com a doença atendidas em um hospital escola do interior do estado de São Paulo. Os resultados foram divididos nos temas: passado, presente e futuro e permearam essas fases a busca pelo significado da doença e pelo suporte social, a importância da religião e espiritualidade e a centralidade da socialização da criança. Conhecer a experiência na doença e a rede social torna-se imprescindível para o planejamento de um cuidado integral. Essa abordagem mostrou-se inovadora para o cuidado à doença crônica.

The deep drop of the fertility rate in Italy to among the lowest in the world challenges contemporary theories of childbearing and family building. Among high-income countries, Italy was presumed to have characteristics of family values and female labor force participation that would favor higher fertility than its European neighbors to the north. We test competing economic and cultural explanations, drawing on new nationally representative, longitudinal data to examine first union, first birth, and second birth. Our event history analysis finds some support for economic determinants of family formation and fertility, but the clear importance of regional differences and of secularization suggests that such an explanation is at best incomplete and that cultural and ideational factors must be considered.

Trata-se de um relato de experiência vivenciada com usuários de crack sob tratamento de desintoxicação, na qual se buscou alcançar o cuidado integral ao ser humano por meio de oficinas de espiritualidade. Cultivadas e dinamizadas a partir de inspirações dos próprios integrantes, as oficinas se constituem em estratégias capazes de estimular o repensar de atitudes e comportamentos, bem como reassumir a vida com base em novos valores e ideais. O relato visa, em suma, contribuir para a ampliação das discussões sobre o tema, oferecendo subsídios para o repensar da prática do enfermeiro no tratamento de desintoxicação, além de assinalar a necessidade de condução de pesquisas nessa área.

The use of precast, prestressed concrete piles in the foundation of bridge piers has long been recognized as a valuable option for bridge owners and designers. However, the use of these precast, prestressed concrete piles in integral abutment bridges has not been widespread because of concerns over pile flexibility and the potential for concrete cracking and deterioration of the prestressing strands due to long-term exposure to moisture. This report presents the details of the first integral abutment bridge in the state of Iowa that utilized precast, prestressed concrete piles in the abutment. The bridge, which was constructed in Tama County in 2000, consists of a 110 ft. long, 30 ft. wide, single-span PC girder superstructure with a left-side-ahead 20º skew angle. The bridge was instrumented with a variety of strain gages, displacement sensors, and thermocouples to monitor and help in the assessment of structural behavior. The results of this monitoring are presented, and recommendations are made for future application of precast, prestressed concrete piles in integral abutment bridges. In addition to the structural monitoring data, this report presents the results of a survey questionnaire that had been mailed to each of the 50 state DOT chief bridge engineers to ascertain their current practices for precast, prestressed concrete piles and especially the application of these piles in integral abutment bridges.

Decline in gait stability has been associated with increased fall risk in older adults. Reliable and clinically feasible methods of gait instability assessment are needed. This study evaluated the relative and absolute reliability and concurrent validity of the testing procedure of the clinical version of the Narrow Path Walking Test (NPWT) under single task (ST) and dual task (DT) conditions. Thirty independent community-dwelling older adults (65-87 years) were tested twice. Participants were instructed to walk within the 6-m narrow path without stepping out. Trial time, number of steps, trial velocity, number of step errors, and number of cognitive task errors were determined. Intraclass correlation coefficients (ICCs) were calculated as indices of agreement, and a graphic approach called "mountain plot" was applied to help interpret the direction and magnitude of disagreements between testing procedures. Smallest detectable change and smallest real difference (SRD) were computed to determine clinically relevant improvement at group and individual levels, respectively. Concurrent validity was assessed using Performance Oriented Mobility Assessment Tool (POMA) and the Short Physical Performance Battery (SPPB). Test-retest agreement (ICC1,2) varied from 0.77 to 0.92 in ST and from 0.78 to 0.92 in DT conditions, with no apparent systematic differences between testing procedures demonstrated by the mountain plot graphs. Smallest detectable change and smallest real change were small for motor task performance and larger for cognitive errors. Significant correlations were observed for trial velocity and trial time with POMA and SPPB. The present results indicate that the NPWT testing procedure is highly reliable and reproducible.

La presente tesis abordó un tema de gran actualidad y pertinencia social: la superación profesional de los docentes de la Enseñanza Básica Integral en atención a la diversidad de niños con necesidades educativas especiales en la República de Cabo Verde, da una respuesta encaminada a la atención a la diversidad en la escuela regular, esta como la diferencia entre culturas, lenguas, valores, sexualidad, género, religión, desarrollo y necesidades educativas especiales asociadas a una discapacidad. Esta necesidad ha sido reconocida en documentos nacionales e internacionales como la Ley General de Educación la Declaración Universal de la UNESCO. Se asume como el proceso de atención psicopedagógica encaminada a los alumnos con necesidades educativas especiales y se considera como uno de los principales retos que la sociedad actual, creciente en su pluralidad, plantea al sistema educativo, y en concreto a las instituciones escolares. Es objetivo del trabajo proponer un sistema de talleres dirigido a la superación profesional de los docentes en la atención a la diversidad de niños con necesidades educativas especiales. Desde el enfoque general dialéctico materialista y los métodos teóricos y empíricos de investigación se modela la solución del problema. Los datos obtenidos revelan las posibilidades de cambios y transformación en el objeto de estudio: la superación de los docentes en la atención a la diversidad necesidades educativas especiales regular.
