Abstract: this article discusses families with per capita income of up to ? of the minimum monthly wage in brazil. the conditions of participation in the labor market and the influence of social security benefits on the pattern of income earned are analyzed. the concern, therefore, is with the importance of social security benefits in attenuating the fragility of the income of these families and the consequences of the gap between their income and the minimum wage for this pattern of income. characteristics of the members of low-income families showed that, in view of the structural changes in the production process and the current juncture of the brazilian economy, persons of active working age lack the pre-requisites for participating with dignity in the world of labor. a study of the composition of the income of the poorest families shows that the income of inactive members (retired persons and pension receivers) is essential in preventing these families from falling below the poverty line. the profile of the members of such families is analyzed on the basis of microdata from the national household survey by sample (pnad/ibge) of 2004, according to age, educational level, color or ethnic group, and participation in the labor market, strictly speaking. factors studied include the type of work exercised and the position in the occupation. the comparison of the profile of members of the poorest families with that of all families shows that the income of retired members and pension receivers are essential not only in reducing the fall in inequality, but basically in reducing poverty itself.

Abstract: Cuando aumenta la percepción ambiental de las personas, tambien se reduce el grado del vandalismo contralos bienes públicos, jardines y plazas, entonces la creencia popular es una inportante estrategia para losplaneamentos y mantenimientos de la arborización urbana. Este estudio tiene como objetivo diagnosticar laopinión de la población de Campos dos Goytacazes (RJ), sobre la forestación de la Plaza Barón del RioBranco. Se hizo un levantamiento cuantitativo de los arboles y se realizó una encuesta a la población (N=175personas). Fueron registrados 40 indivíduos de 10 especies distribuídas en las famílias Anacardiaceae,Combretaceae, Chrysobalanaceae, Fabaceae, Lythraceae y Moraceae. En relacion al origen geografico, 6 delas especies fueron nativas (Brasile as) y 4 fueron exóticas. La Licania tomentosa (oiti) predomino en lademonstración (55%), seguida de la Schinus terebinthifolius (aroeira-mansa) (15%) y Senna siamea (cássiasiamesa)(7,5%). La población utiliza la plaza para relajamiento (54,28%) y socialización (31,44%), por serconsiderada muy forestada (60%) y su principal ventaja es el sombreamiento (57%). Sugún la población, laforestación de la plaza no presenta desventaja (51%), a no ser por la suciedad de tallos y hojas (23%). Laplaza fue considerada sin importancia para la fauna urbana (100%). El mantenimiento de la plaza es buenasegún la mayoría (75%), todavía la administración debe mejorar el jardin (100%), la seguridad (69%), cuidarde personas que viven en la calle (26%), mejorar la recogida de basura (23%) y recoger los perros callejeros(23%). Las personas no son favorables a la tributación pública para la forestación o jardinamiento (60%). Lamajoria cree que el mantenimiento de la plaza es responsabilidad de la administración municipal (93%), y esresposabilidad de la población el no vandalismo contra la vegetatación (68,6%). La población sabe de laimportancia histórica del local, mas desconoce la própria historia, pero reconoce la importanciaarquitectónica y el potencial turístico.

Abstract: La arborización urbana forman parte del ecosistema de las ciudades, promoviendo beneficios que merecen laatención del poder público. La arborización sin planeamiento genera serios problemas de incompatibilidad conlos paseos y equipamientos públicos, muros, redes hidráulicas, eléctricas y de telecomunicaciones. Este estúdiotiene como objetivo hacer el levantamiento e identificar las condiciones de la arborización en las inmediacionesde la Plaza Bar o do Rio Branco (Plaza del Liceo de Humanidades) en el Barrio Jardín Maria de Queiroz,Campos dos Goytacazes, Rio de Janeiro, Brasil. Los parámetros para la recopilación de datos fueron, laidentificación de las especies, origen, situación de la raíz, área libre del entorno de la raíz, altura de la primerabifurcación, tipo de poda y situación de conflicto de la copa con la red de cables eléctricos del área. Fueronregistrados 151 indivíduos pertenecientes a 25 especies, distribuidos en 21 géneros y 15 familias botánicas. Seconstató una relación de 1 especie nativa para 1,5 especies exóticas. Los árboles que presentaron raícesexpuestas que da aban las aceras totalizaron 59%. La disponibilidad del área del entorno de las plantas no fuerespetada (no existe) en 84,11% de los casos, el 8,61% de los árboles de esa área era ≥ 1,00 m2, y en el 7,28% delos casos era < 1,00 m2. En el 33% de los árboles a la altura de la primera bifurcación estaba por encima de 1,80m del suelo; 50,33% presentaban algún tipo de poda y de esas fueron consideradas mutilaciones el 15,23%. En el10,60 % de los casos, los árboles impedian el paso de los peatones en las aceras y el 31,79 % estaban enconflicto con los cables eléctricos del área.

Abstract: Beyond the production of silk thread, there are several studies showing that the silk is a great biomaterial for surgical sutures and grafts. This paper shows a new technique to produce silk thread changing the natural cycle of silk production, which is the production of cocoons. This new method has the purpose of producing a silk fabric free of impurities, through flat surfaces. Six different surfaces were tested: Glass, Formica Surface, Steel and Zinc Sheets, Cotton tissue and Burlap Bag. The first five surfaces had not presented enough larvae alive for statistical analysis, because there were several damages in silkworms larvae that resulted in mortality and low silk production. On the other hand, the burlap bag surface presented good results for web construction by biospinning and its use was indicated for silk industry focused on biomaterials. The present study suggested the potential of naturally biospun web, using Bombyx mori, to develop a new technique to produce silk thread matrices that will have several applications at the industry and production of biomedical materials.

Abstract: gait is the most common activity performed by humans, being a fundamental motor ability to locomotion. however, ageing is characterized by a gradual reduction of the locomotor apparatus efficiency which occurs by the decrease in strength, muscle mass and flexibility. this study aimed to verify the transient effect of a single session of hip extensor and flexor muscles stretching exercises over gait in elderly subjects. five elderly ladies (67.0 ± 3.8 years 1.59 ± 0.07 m; 64.3 ± 15.3 kg) volunteered to participate in the study. gait analysis was performed before and after stretching exercises. the stretching protocol was applied in a single session and consisted of three static stretching exercises conducted during 30s for the hip joint flexor and extensor muscles. after the stretching session, participants' gait showed reduced pelvic anterior tilt peak, greater hip range of motion and extension peak, greater knee range of motion, greater knee peak flexion angle during the mid swing and greater toe clearance (28.6%). results showed that immediately after a stretching session, the elderly women presented alterations in the gait pattern in which some variables suggest a reduced risk of fall. the effects of ageing over some variables were partially reversed and the participants presented a gait pattern more similar to young adults than before stretching.
