A Reeducação Postural Global (RPG) e as Autoposturas Respiratórias de Philippe Souchard, implicações na prática vocal/coral

A Investigação científica que se apresenta enquadra-se no âmbito do Projeto Educativo, integrado no Mestrado em Ensino da Música, especialidade em Música de Conjunto, realizado no Conservatório Superior de Música de Gaia (CSMG). Esta Investigação-ação, de análise qualitativa, centrou-se na implementação de um Programa de Intervenção: A Reeducação Postural Global (RPG) e As Autoposturas Respiratórias, na Produção Sonora Musical no Canto (Philippe Souchard, 1987; 1997; 2011). Assente no modelo de Relação Pedagógica (RP) de Renald Legendre (2005), teve como Sujeitos (S) de aprendizagem dois grupos das Classes de Conjunto de Coro, da Fundação Conservatório de Música de Gaia: o Grupo de Ação (GA) e o Grupo de Controlo (GC). Aplicadas sessões de fisioterapia ao GA, ambos os grupos interpretaram a Obra Coral Pange Lingua, de Zoltán Kodály. Pelos registos apresentados na análise de dados, ditos em diários de bordo dos Sujeitos (S) e do Agente (A) professor da Classe de Conjunto, e em imagens fílmicas e fotográficas realizadas, verificamos a eficácia deste Programa. À luz dos exercícios da Reeducação Postural Global (RPG) e das Autoposturas Respiratórias, de Philippe Souchard, aplicados ao estudo da obra mencionada, pudemos verificar que os Sujeitos (S) do Grupo de Ação apresentaram progressos vocais de significativa importância.

Herramienta para mejorar la afinación vocal en Android

In this paper, a tool to improve vocal tuning in Android devices is presented. This application aims to offer exercises to practice and improve singing skills. The designed tool includes two main functionalities: sound synthesis, to provide with singing sound references, and fundamental frequency analysis, to analize the sound and check if the user sings the right musical note. The well-known Yin algorithm has been selected to perform the fundamental frequency analysis. Three different singing exercises are included: sing single notes, sing intervals and sing a note in order to complete a chord. The system also includes a graphical interface in which musical notation is employed to write down the singing sound. The system has been evaluated in order to test out its correct performance regarding both the analysis and synthesis of musical sounds.

A New Species Of Pseudopaludicola Miranda-ribeiro, 1926 (anura: Leptodactylidae: Leiuperinae) From Northwestern State Of São Paulo, Brazil.

A new species of Pseudopaludicola is described from human-altered areas originally covered by Semideciduous Forest in northwestern state of São Paulo, southeastern Brazil. Morphologically, the new species differs from four species belonging to the P. pusilla group by the absence of either T-shaped terminal phalanges or toe tips expanded, and from all other congeners except P. canga and P. facureae by possessing an areolate vocal sac, with dark reticulation. The higher duration (300-700 ms) of each single, pulsed note (9-36 nonconcatenated pulses) that compose the call in the new species distinguishes it from all other 14 species of Pseudopaludicola with calls already described (10-290 ms). Absence of harmonics also differ the advertisement call of the new species from the call of its sister species P. facureae, even though these two species presented unexpected low genetic distances. Although we could not identify any single morphological character distinguishing the new species from P. facureae, a PCA and DFA performed using 12 morphometric variables evidenced significant size differences between these two species. 

Dysphagia Progression And Swallowing Management In Parkinson's Disease: An Observational Study.

Dysphagia is relatively common in individuals with neurological disorders. To describe the swallowing management and investigate associated factors with swallowing in a case series of patients with Parkinson's disease. It is a long-term study with 24 patients. The patients were observed in a five-year period (2006-2011). They underwent Fiberoptic Endoscopic Evaluation of Swallowing, Functional Oral Intake Scale and therapeutic intervention every three months. In the therapeutic intervention they received orientation about exercises to improve swallowing. The Chi-square, Kruskal-Wallis and Fisher's tests were used. The period of time for improvement or worsening of swallowing was described by Kaplan-Meier analysis. During the follow-up, ten patients improved, five stayed the same and nine worsened their swallowing functionality. The median time for improvement was ten months. Prior to the worsening there was a median time of 33 months of follow-up. There was no associated factor with improvement or worsening of swallowing. The maneuvers frequently indicated in therapeutic intervention were: chin-tuck, bolus consistency, bolus effect, strengthening-tongue, multiple swallows and vocal exercises. The swallowing management was characterized by swallowing assessment every three months with indication of compensatory and rehabilitation maneuvers, aiming to maintain the oral feeding without risks. There was no associated factor with swallowing functionality in this case series.

Sintomas vocais e sensações laríngeas em trabalhadores de uma usina de álcool e açúcar expostos a riscos ocupacionais

OBJETIVO: Investigar os sintomas vocais e sensações laríngeas dos trabalhadores de uma usina de álcool e açúcar expostos a ruído e/ou substâncias químicas. MÉTODOS: Participaram 289 trabalhadores de uma usina de álcool e açúcar distribuídos em cinco grupos expostos (I- ruído; II- ruído, óleo, graxa, derivação de petróleo; III- ruído, ácidos, sulfatos, cloretos, nitratos; IV- ruído, poeiras respiráveis e sílica livre cristalizada; V- óleo, graxa, derivação de petróleo) e um grupo controle que responderam o questionário Condições de Produção Vocal - Professor adaptado à categoria profissional. Os grupos foram comparados em relação aos sintomas vocais, sensações laríngeas, tabagismo e riscos físicos e químicos. Esta comparação foi realizada por meio de análise estatística. RESULTADOS: O sintoma vocal e a sensação laríngea mais relatados pelos trabalhadores foram voz grave e tosse com catarro, respectivamente. Considerando o risco físico no ambiente de trabalho, os grupos I e IV foram os que mais citaram presença de ruído. Devido à sua exposição, os mesmos aumentavam a intensidade da voz (Efeito de Lombard-Tarneaud) e, assim, mencionaram sintomas vocais. Em relação aos riscos químicos no ambiente ocupacional, o grupo IV foi o que mais referiu presença de poeira e fumaça, e estas eram compostas por poeiras respiráveis e sílica. Tais exposições ocasionam sintomas vocais e sensações laríngeas e, consequentemente, alterações vocais. CONCLUSÃO: Sintomas vocais e sensações laríngeas podem estar relacionados a atividade profissional em que haja exposição a riscos físicos e/ou químicos.

HYBRID, SUBSPECIES, OR SPECIES? THE VALIDITY AND TAXONOMIC STATUS OF PHAETHORNIS LONGUEMAREUS AETHOPYGA ZIMMER, 1950 (TROCHILIDAE)

Phaethornis longuemareus aethopyga was described by John T. Zimmer in 1950 and treated as a valid subspecies until it was proposed that the three known specimens were hybrids between R ruber and P. rupurumii amazonicus. On the basis of some recently collected specimens, we reevaluated the validity of P. l. aethopyga. Despite showing some differences related to age and sex, all specimens agree in the general plumage pattern and are fully diagnosable when compared with any other taxon of the genus. The hypothesis of a hybrid origin becomes unsustainable when one notes that (1) P. l. aethopyga has characters that are unique and absent in the purported parental species, such as the white outer margins at the base of the rectrices; and (2) P. l. aethopyga occurs far from the distribution of one of the alleged parental species. Furthermore, field data show that P. l. aethopyga has attributes typical of a valid and independent taxon, such as lekking behavior. Therefore, given its overall diagnosis, P. aethopyga could at least be treated as a phylogenetic species. Yet its morphological and vocal distinctiveness with respect to other Phaethornis spp. in the ""Pygmornis group"" is greater than that observed between some species pairs traditionally regarded as separate biological species within the group, which supports its recognition as a species under the biological species concept.

Influence of anabolic steroid treatment associated to physical exercise in the ultrasonic vocalization of rats

Unlike humans, who communicate in frequency bands between 250 Hz and 6 kHz, rats can communicate in frequencies above 18 kHz. Their vocalization types depend on the context and are normally associated to subjective or emotional states. It was reported significant vocal changes due to administration of replacement testosterone in a trained tenor singer with hypogonadism. Speech-Language Pathology clinical practices are being sought by singers who sporadically use anabolic steroids associated with physical exercise. They report difficulties in reaching and keeping high notes, ""breakage"" in the passage of musical notes and post singing vocal fatigue. Those abnormalities could be raised by the association of anabolic steroids and physical exercise. Thus, in order to verify if this association could promote vocal changes, maximum, minimum and fundamental frequencies and call duration in rats treated with anabolic steroids and physically trained (10 weeks duration) were evaluated. The vocalizations were obtained by handling the animals. At the end of that period, rats treated and trained showed significant decrease in call duration, but not in other parameters. The decrease in call duration could be associated to functional alterations in the vocal folds of treated and trained animals due to a synergism between anabolic steroids and physical training.

Aerodynamic study of three-dimensional larynx models using finite element methods

The airflow velocities and pressures are calculated from a three-dimensional model of the human larynx by using the finite element method. The laryngeal airflow is assumed to be incompressible, isothermal, steady, and created by fixed pressure drops. The influence of different laryngeal profiles (convergent, parallel, and divergent), glottal area, and dimensions of false vocal folds in the airflow are investigated. The results indicate that vertical and horizontal phase differences in the laryngeal tissue movements are influenced by the nonlinear pressure distribution across the glottal channel, and the glottal entrance shape influences the air pressure distribution inside the glottis. Additionally, the false vocal folds increase the glottal duct pressure drop by creating a new constricted channel in the larynx, and alter the airflow vortexes formed after the true vocal folds.

Media influence to suicide: The search for solutions

This review explores the influence to suicide in print and electronic media, and considers both real and fictional deaths. The conclusion appears inescapable that reports about celebrities which are multi-modal, repeated, explicit, front page, glorify the suicide, and describe the method lead to an increase in deaths from suicide, particularly in the region in which reports are published. The paper argues that even if there was multi-national agreement to international guidelines, media will continue to report suicide when it is considered to be a matter of public interest. What appears crucial is a collaborative approach between professionals and the media to promote a negative attitude toward suicide without increasing stigma toward those with mental health problems.

Cultural revolution in whale songs

Humpbacks have picked up a catchy tune sung by immigrants from a distant ocean. The song patterns of humpback whales (Megaptera novaeangliae) depend on where they live, with populations inhabiting different ocean basins normally singing quite distinct songs. Here we record a unique and radical song change in the song of humpback whales in the Pacific Ocean off the Australian east coast. Their song was replaced rapidly and completely by the song of the Australian west coast population from the Indian Ocean, apparently as a result of the introduction of only a small number of 'foreign' singers. Such a revolutionary change is unprecedented in animal cultural vocal traditions and suggests that novelty may stimulate change in humpback whale songs.

T-Shaped Microsuture: A New Suture Technique for Laryngeal Microsurgery

To describe a new suture technique for laryngeal microsurgery and to test its applicability in human cadaver larynges. The new technique was experimentally tested in freshly excised human larynges fixed to a larynx holder appropriate for the simulation of laryngeal microsurgery. A mucosal flap was created in the vocal fold for the fabrication of a pocket for subepithelial fat implantation, and the wound edges were then brought together and sutured using the proposed technique. The time necessary for suture was measured with a stopwatch for five successive sutures performed by one of the surgeons. The presence or absence of mucosal rupture was determined for five sutures performed by two surgeons, for a total of 10 sutures. The sutures were performed without the help of an assistant, with no laceration of the mucosa being observed in any of the attempts, and within a relatively short period of time even without previous training. The sutures performed permitted the implanted fat to remain stable under the mucosal flap. Conclusions: the new suture technique is an easy procedure, which can be performed by a single surgeon under microscopic vision, with a low risk of tissue rupture. The technique does not markedly prolong the duration of surgery and a single suture thread can be used for the fabrication of more than one stitch.

Effects of proportional assisted ventilation on exercise performance in idiopathic pulmonary fibrosis patients

Background: Patients with idiopathic pulmonary fibrosis (IPF) present an important ventilatory (imitation reducing their exercise capacity. Non-invasive ventilatory support has been shown to improve exercise capacity in patients with obstructive diseases; however, its effect on IPF patients remains unknown. Objective: The present study assessed the effect of ventilatory support using proportional, assist ventilation (PAV) on exercise capacity in patients with IPF. Methods: Ten patients (61.2 +/- 9.2 year-old) were submitted to a cardiopulmonary exercise testing, plethysmography and three submaximal. exercise tests (60% of maximum load): without ventilatory support, with continuous positive airway pressure (CPAP) and PAV. Submaximal tests were performed randomly and exercise capacity, cardiovascular and ventilatory response as well as breathlessness subjective perception were evaluated. Lactate plasmatic levels were obtained before and after submaximal. exercise. Results: Our data show that patients presented a limited exercise capacity (9.7 +/- 3.8 mL O(2)/kg/min). Submaximal. test was increased in patients with PAV compared with CPAP and without ventilatory support (respectively, 11.1 +/- 8.8 min, 5.6 +/- 4.7 and 4.5 +/- 3.8 min; p < 0.05). An improved arterial oxygenation and lower subjective perception to effort was also observed in patients with IPF when exercise was performed with PAV (p < 0.05). IPF patients performing submaximal exercise with PAV also presented a lower heart rate during exercise, although systolic and diastolic pressures were not different among submaximal tests. Our results suggest that PAV can increase exercise tolerance and decrease dyspnoea and cardiac effort in patients with idiopathic pulmonary fibrosis. (C) 2009 Elsevier Ltd. All rights reserved.
