Efeitos do laser de baixa intensidade em780nm sobre a performance muscular aeróbica de ratos em treinamento físico em esteira
(Universidade Federal de São Carlos, 2004-12-14) Vieira, Wouber Hérickson de Brito; Parizotto, Nivaldo Antonio; https://lattes.cnpq.br/5527703735628408
The purpose of this study was to evaluate relative the physiological adaptation the activities of enzymes Lactate Dehidrogenase LDH (glycolytic) e Citrate Synthase CS (oxidative) and to the Anaerobic Threshold (AT), to the exercise in treadmill in rats submitted to the photostimulation for low-intensity laser (780 ηm) in the main participant muscles of the march. Fifty-four male Wistar rats had been part of the study. These animals were divided in four groups: Two had remained in rest (1) GRC, being one of them irradied (2) GRL, and other two were submitted to an aerobic treadmill training program during 5 weeks and to a multistage treadmill test of increasing intensity (3) GEC, being one of them irradied (4) GEL. The irradiation for infra-red laser (780 ηm) was made daily in number of four (quadriceps, maximum glúteo, soleus, tibialis anterior) in each back leg of the animals, totalizing 8 applications for animal/day, using (dose, 3,8 J/cm2; power, 15 mW; time, 10 s, continuous) during 5 weeks consecutives. The multistage treadmill tests of increasing intensity were made once a week totalizing 5 evaluation, in order to obtain blood samples for determination of the AT. In the analyses electrophoretics and spectrophotometic of the LDH and CS muscles samples (soleus, TA and cardiac) were removed 48 hours after the last exercise bout. The laser to promote increase in the oxidative metabolism of 2% a 78%, the exercise of 18% a 75%, and action combined of 43% a 92%; Apparent systemic action of the laser was detected in cardiac muscle with increase in the activity of the CS and reduction of the LDH. The group GEC and GEL showed increase in the maximum speed, in the speed corresponding to the AT and a trend reduction of the blood lactate concentration during the training period. However, no significant difference occurred between two groups though the GEL had shown higher values. These data suggest that the aerobic treadmill-training partner to the low-intensity laser can to promote physiological adaptation in the direction of increase oxidative capacity in the animals, represented by increase of the CS, reduction of the LDH and by the higher degree of effort to reach the Anaerobic Threshold. This similarity has a utility therapeutic practical.
Incorporação e apropriação dos resultados de uma intervenção ergonômica: um estudo de caso
(Universidade Federal de São Carlos, 2004-12-14) Cockell, Fernanda Flavia; Camarotto, João Alberto; https://lattes.cnpq.br/1427853773681255
The recent changes in the work s world have modified and amplified the performance field of the ergonomics. Through a brief methodological discussion about the Ergonomic Work Analysis and a bibliographical revision about undertaken ergonomic interventions, it was verified that the results of work transformation through Ergonomic Work Analysis not always will be positive. Consequently, this work had an objective of analyzing an ergonomic intervention accomplished in a powdered detergent company, due to understand how ergonomic actions are incorporated for the different social actors and how the company, through the management, could appropriate of the results in behalf of the production. The process of activity transformation of the Vincador, from the initial demand for recommendations implemetation and validation, as well as the established social relationships and the Vincadores roles, managers, Internal Committee of Ergonomics and the company were analyzed under the Ergonomic Work Analysis point of view. The results showed that Vincadores work rhythm has increased after the ergonomic recommendations implemetation as a consequence of management s appropriation of regulations margins, whose intention was to increase the process effectiveness without considering the balance between health versus productivity. The non-incorporation of the activity point of view helped, therefore, that changes of interests, values and the involved actors logic s, lead to commitment break, before firmed among those, turning the new situation noxious for the Vincadores health.
A política municipal de habitação na cidade de Santos – SP na década de 1990
(Universidade Federal de São Carlos, 2004-12-14) Braga, Rosana Aló Maluza; Francisco, José; https://lattes.cnpq.br/0330065027402518; https://lattes.cnpq.br/9578662465540379
This paper aims to show the governmental action on the Housing Municipal Policy implementation on the 1990´s within Santos City, São Paulo State. To do so, it was made a research about the Federal Housing Policy on the BHN period and also on the posterior period till 2000 in order to verify the trajectory of the federal policy on the housing field. The Municipal Housing Policy conquered special importance after the promulgation of the 1988 Constitution when the Federal Government gave to the municipalities the responsibility for their own urban policies. Within this research, we aim to present the factors that influenced the formulation and implementation process and the results of such policy in this period. We presented this policy content on three distinct administrations associated with the instruments which made the implementation possible: The ZEIS law – Special Zones for Social Interest, the FINCOHAP – Popular Housing Construction Incentive Fun, Municipal Housing Council and the Municipal Housing Conferences. This choice for Santos City is due to the master student has been a participant person on the Santos Housing Policy process. The used methodology was based on gaining information through out the hypotheses made for this research. It has been verified, with this study, that Federal Government on the BNH age had the same housing policy for many Brazilian cities, not considering the specificities of each one, conceiving resources for housing constructions. On the post 1988 Constitution period, the municipalities began an autonomy process of their urban politics. On the Housing field, the Federal Government gave the responsibility for the federative institutions in order to formulate their policies without conceiving resources. Generalizing, so these new policies let the cities economically dependent on the Federal Government which don’t have federal channel to redirect resources like for Health and Education, making impossible the municipality to supply its housing deficit by their own.
