Desenvolvimento motor de criança com paralisia cerebral: Avaliação e intervenção

The objective of this study was to analyze the motor development of a ten year old child with ataxic cerebral palsy and the effects of a motor activities program in the swimming pool. Motor development was measured according to the motor assessment and the intervention program of motor activities in the swimming pool conducted at Sesi/Londrina, twice a week, during 45 minute sessions over a 2 month period, with an attendance rate of 87%. Data was analyzed descriptively comparing the results with before and after tests. Generally, the motor quotient regarding all items was classified as very low, characterizing motor deficit, with exception of temporal organization, presented as normal low. After intervention, the only area that showed positive change was balance; this result showed that the child gained 12 months in motor age, without corresponding alterations in the other areas.

Comparison between protocols for the determination of anaerobic threshold in adolescent swimmers

Aim. The purpose of this study was to compare the anaerobic threshold speed (AT) obtained from fixed lactate blood concentrations (AT 4 mM and AT 3.5 mM), lactate minimum speed (LM) and critical speed (CS), determined from different distances in fifteen Brazilian national level swimmers (10 boys = 14.8 ± 0.6 years old and 5 girls = 14.6 ±0.8 year-old). Methods. The tests to determine the AT 4 mM, AT 3.5 mM, LM and CS were performed in a 25 m swimming pool and consisted of 7 or 8 evaluations separated by 24-48 h intervals. Data were submitted to analysis of variance (ANOVA) for repeated measures, followed by the post hoc Scheffé test and Pearson correlation coefficients. Significance was set at P<0.01. Results. There were no significant differences among the values for AT 4 mM and CS1 (1.34 ± 0.05 vs. 1.33 ± 0.05 m.s -1, respectively). However, AT 4 mM and CS1 were significantly higher than AT 3.5 mM (1.28 ± 0.04 m.s -1), LM (1.27 ± 0.05 m.s -1), CS2 (1.26 ± 0.06 m.s -1), CS3 (1.27 ± 0.06 m.s -1) and CS4 (1.25 ± 0.07 m.s -1). There were no significant differences among the values for AT 3.5 mM, LM, CS2, CS3 and CS4. Conclusion. The results obtained in this study suggest that the anaerobic threshold determined by a fixed lactate concentration of 3.5 mM, as well as the LM and the CS methods determined by different distances, seem to be the most appropriate indexes for the evaluation of aerobic capacity in adolescent swimmers.

Natação Adaptada: análise da função pulmonar de pessoas com deficiência

The research discusses the pulmonary function of the students of SORRI that are part of the Project for the extension of the Department of Physical Education in Bauru Swimming for People with Disabilities during the aquatic activities, noting the changes in efficiency class of breathing with the practice of aquatic activity, by the analysis of the volume and respiratory capacity. The respiratory control is essential in the process of adaptation to the liquid medium, because a student who fails to immerse the face in the water will not be able to adopt a horizontal position sufficiently stable. The practice of aquatic activities requires a great effort of breathing. Therefore, the practice of aquatic activities influence favorably the breathing, because the movements performed in the water tone the diaphragm, which is the essential muscle of the breathing, allowing an improvement in pulmonary ventilation. For the purposes of this study, the sample was composed of 10 students of the SORRI of the city of Bauru forming part of the project Swimming for People with Disabilities, practicing swimming once a week for 1 hour. For the collection of lung volumes and capacities was used a transducer of air flow and a unit of data collection, model MP36, both of the brand Biopac connected to a computer, where the data were collected and recorded for later analysis. Two tests were carried out in a day with each participant in the project of swimming, and a test at the beginning of the lesson, at rest, and another after a series of 10 breaths carried out within the swimming pool. These tests were performed in the months of March and April. The analysis of the data was through the medium of the figures and also individually, noting the changes in respiratory function of students practicing aquatic activities, without which there would be no comparison between the participants. The measurements of the scores on the pre- and post-exercise show that the...

Variáveis determinantes do desempenho em provas de curta duração em nadadores masters

Twenty-four masters swimmers participated in the study (42.0 ± 7.4 years, 1.74 ± 0.09 m, 74.8 ± 14.1 kg). Countermovement jump (CMJ) and 3 kg medicinal ball throwing (BM) were performed. At a 25 m swimming pool, each subject completed a maximal 50 m front crawl swim with in water start, 25 and 50 m performances (T25, T50) were recorded. Anaerobic critical velocity (AnCV) was determined by the slope of the distance-time relationship (Dd-t) in the two swimming distances. T25 and T50 (respectively 19.0 ± 2.7-sec and 38.8 ± 6.4-sec) were correlated with CMJ (27.2 ± 5.0 m) (respectively, r = -0.78 and -0.73, p < 0.01), and BM (4.3 ± 1.0 m) (r = -0.68 and - 0.58, p < 0.01). AnCV25,50 (1.31 ± 0.23 m.s-1 ) was correlated with T25 (r = -0.92, p < 0.01 ) and T50 (r = -0.98, p < 0.01). The strength parameters turn out to be important in aquatic performance in masters swimmers and AnCV may be relevant in the training of masters swimmers.

Disseminated Mycobacterium marinum infection with extensive cutaneous eruption and bacteremia in an immunocompromised patient

Mycobacterium marinum can cause fish tank granuloma (or swimming pool or aquarium granuloma) in immunocompetent patients. Dissemination of Mycobacterium marinum-infection is a rare condition which occurs mainly in immunocompromised patients and can be life-threatening. We report the case of an 87-year-old woman who was treated with oral corticosteroids for polymyalgia rheumatica for many years and developed erythema nodosum-like lesions on the right forearm and arthritis of the right wrist. By increasing the steroid dosage and adding methotrexate only short-term remission was achieved. Seven months later painful erythematous nodules occurred on all extremities which became necrotic, ulcerative and suppurative. Ziehl-Neelsen staining revealed acid-fast bacilli and Mycobacterium marinum was cultured from skin biopsies, blood, and urine. The critically ill patient was treated with clarithromycin and ethambutol resulting in a dramatic improvement of the general condition. After four months, doxycycline had to be added because of new skin lesions. This case illustrates the impact of Mycobacterium marinum infection in immunocompromised patients.

Körper im Kulturkonflikt. Zur Vermittlung und Aushandlung von Normen und Werten in Schwimmkursen für Frauen mit Migrationshintergrund

Ausgehend vom Körper als Vermittler zwischen Subjekt und Gesellschaft wird die Frage beantwortet, wie Migrantinnen auf diskursiv erzeugte Normen und Werte der schweizerischen Mehrheitsgesellschaft im Kontext von Schwimmkursen als Integrationsmaßnahme reagieren. Die Feldaufenthalte und Interviews erlauben eine Analyse dominanter Macht- und subversiver Selbstermächtigungsprozesse innerhalb eines körperzentrierten, religiös-kulturell pluralisierten und ethnisch differenzierten Feldes. Hierbei werden Divergenzen in der verkörperten und objektiven Sozialstruktur sichtbar, was sich beispielsweise in den kontrovers geführten Debatten zur Wahl der Badekleidung und Badnutzung verdeutlicht. Bei den Aushandlungen um die Durchsetzung von Deutungs- sowie Ordnungsmustern lassen sich Prozesse der kulturellen Anpassung, Anknüpfung und des Neuentwurfs beobachten.

Pollen analysis of soil samples from the A.D. 79 level. Boscoreale, Oplontis, and Pompeii

Fifty samples of Roman time soil preserved under the thick ash layer of the A.D.79 eruption of Mt Vesuvius were studied by pollen analysis: 33 samples from a former vineyard surrounding a Villa Rustica at Boscoreale (excavation site 40 x 50 m), 13 samples taken along the 60 m long swimming pool in the sculpture garden of the Villa of Poppaea at Oplontis, and four samples from the formal garden (12.4 x 17.5 m) of the House of the Gold Bracelet in Pompeii. To avoid contamination with modern pollen all samples were taken immediately after uncovering a new portion of the A.D. 79 soil. For comparison also samples of modern Italian soils were studied. Using standard methods for pollen preparation the pollen content of 15 of the archaeological samples proved to be too little to reach a pollen sum of more than 100 grains. The pollen spectra of these samples are not shown in the pollen tables. (Flotation with a sodium tungstate solution, Na2WO4, D = 2.05, following treatment with HCl and NaOH would probably have given a somewhat better result. This method was, however, not available as too expensive at that time.) Although the archaeological samples were taken a few meters apart their pollen values differ very much from one sample to the other. E.g., at Boscoreale (SW quarter). the pollen values of Pinus range from 1.5 to 54.5% resp. from 1 to 244 pine pollen grains per 1 gram of soil, the extremes even found under pine trees. Vitis pollen was present in 7 of the 11 vineyard samples from Boscoreale (NE quarter) only. Although a maximum of 21.7% is reached, the values of Vitis are mostly below 1.5%. Even the values of common weeds differ very much, not only at Boscoreale, but also at the other two sites. The pollen concentration values show similar variations: 3 to 3053 grains and spores were found in 1 g of soil. The mean value (290) is much less than the number of pollen grains, which would fall on 1 cm2 of soil surface during one year. In contrast, the pollen and spore concentrations of the recent soil samples, treated in exactly the same manner, range from 9313 to almost 80000 grains per 1 g of soil. Evidently most of the Roman time pollen has disappeared since its deposition, the reasons not being clear. Not even species which are known to have been cultivated in the garden of Oplontis, like Citrus and Nerium, plant species with easily distinguishable pollen grains, could be traced by pollen analysis. The loss of most of the pollen grains originally contained in the soil prohibits any detailed interpretation of the Pompeian pollen data. The pollen counts merely name plant species which grew in the region, but not necessarily on the excavated plots.

Great marquee in the new railway station on Málaga

The commercial centre VIALIA and the new railway station of the AVE (high speed train) in Malaga was inaugurated in November 2006, just on the place of the former railway station. The new railway station with an investment of 134,7 million Euros occupies a surface of 51.377 m2, five times the surface of the former station. The enclosure is the biggest intermodal and commercial centre of Spain which comprises a parking of 21.000 m2 for 1300 parking places, one commercial area and a hotel with a total extension constructed of approximately 100.000 m2. The spaces of leisure contain cinemas, shops, restaurants, bowling, gymnasium, swimming pool and zones of passenger's traffic.

Evolução das doses no ambiente do Reator IEA-R1 e tendências com base nos resultados atuais

O Ipen/Cnen-SP possui um Reator de Pesquisa(IEA-R1) em operação desde 1957. Ele utiliza água leve como blindagem, moderador e como fluido refrigerante, o volume desta piscina é de 273m3. Até 1995 a operação do Reator era descontinua, ou seja, operava diariamente sendo desligado no final do dia, a uma potência de 2,0 MW. A partir daquele ano, após algumas modificações de segurança, o Reator passou a operar de forma continua, ou seja, de segunda-feira a quarta-feira sem ser desligado, totalizando 64 horas semanais. A potência também foi aumentando até 4,5 MW em 2012. Em virtude dessas alterações, a saber, operação contínua e do aumento da potência, as doses dos trabalhadores aumentaram e por isso foram realizados vários estudos para diminui-las. Estudos demonstraram que uma das principais limitações para operação de um reator em potência elevada, provém das radiações gama emitidas pelo sódio-24. Outros elementos como magnésio-27, Alumínio-28, Argônio-51, contribuem de forma considerável para a atividade da água da piscina. A introdução de uma camada de água quente em sua superfície, estável e isenta de elementos radioativos com 1,5m a 2m de espessura constituiria uma blindagem às radiações provenientes dos elementos radioativos dissolvidos na água. Estudos de otimização provaram que a instalação da camada quente não era necessária para o regime e potência atual de operação do Reator, pois outros procedimentos adotados eram mais eficazes. A partir desta decisão o serviço de Proteção Radiológica do Reator IEA-R1, montou um programa de avaliação das doses para certificar-se de que elas se mantinham em valores razoáveis baseados em princípios estabelecidos em normas nacionais e internacionais. O intuito deste trabalho é realizar uma análise das doses individuais dos IOE (Individuo Ocupacionalmente Expostos), considerando as mudanças no regime de operação do Reator e sugerir opções de proteção e segurança, viáveis em primeira instância, para reduzir as doses analisadas, visando se chegar aos níveis de referencia de 3 mSv/ano adotados pela instalação em apreço.

Integration of Sustainable Development Principles into a Community Park

Characteristics of six operating hot spring recreational facilities were reviewed to identify opportunities for integrating a range of sustainable design and operation approaches into a community park. Potential operating cost savings were evaluated for a conceptual landscape project, bathhouse project, and swimming pool project that reduced the use of electricity, natural gas, water, the discharge of water, and solid waste generation. The projects showed a combined cost savings of approximately $40,000 per year by adopting passive solar design, energy efficient lighting, native vegetation, water efficient fixtures, and a natural swimming pool. The greatest potential operating cost reductions were observed for cutbacks in the use of swimming pool water and reductions in natural gas needed for building and swimming pool heating.
