<p dir="ltr">Experiments were performed in the Boeing/AFOSR Mach-6 Quiet Tunnel to study the effect of flight-derived discrete roughness elements repeated in an axisymmetric pattern near the nose of a sharp 7° cone. The aim of the roughness array was to simulate natural vehicle roughness and attempt to introduce a deterministic roughness pattern with the ability to cancel out the instabilities caused by the natural roughness. The cone was pitched at a 6° of attack to determine the three-dimensional flow field effects of the roughness elements. Tests were also ran at 0° of attack for comparison. Quiet flow testing included the designed-for freestream unit Reynolds number of 10.8x10⁶, and Reynolds numbers above and below. In noisy flow, comparable Reynolds numbers were also tested at to isolate the effects of noise in a conventional flow wind tunnel.</p><p dir="ltr">Infrared thermography and surface pressure sensors were used to document the behavior of the boundary layer. It was found that the roughness pattern was in general unsuccessful in controlling the added boundary layer instabilities as intended at 6° of attack, but it did create different instability amplitudes and heating patterns. Additionally, it was determined to reduce Mack's second-mode instability amplitudes at 0° of attack.</p><p dir="ltr">Additionally, work was done to document and characterize the roughness patterns found on samples of hypersonic glide vehicles PRIME (SV-5D or X-23) and ASSET (ASV-3). These samples were taken in the form of molded impressions of the surface which were able to be analyzed with an optical profilometer and considered for future experimental distributed roughness studies.</p>

<p dir="ltr">The Boeing-AFOSR Mach-6 Quiet Tunnel (BAM6QT) was used for a set of experiments aiming to characterize the stability regimes of stagnation point injection in noisy and quiet flow across an array of different injected gases. Four gases were used in this experiment: air, helium, carbon dioxide, and argon. These gases were injected at varying thrust coefficients, ranging from 0.0516 to 0.5666, using a 7 degree half-angle cone with a 19 mm radius spherical nose and a single 1.93 mm-radius sonic jet in the center of the model. The primary data collected consists of schlieren images gathered at a sample rate of 76 kHz. These data were then analyzed using a shock tracking software to measure the physical locations of flow features as well as through spectral proper orthogonal decomposition (SPOD) to analyze specific modes in the flow.</p><p dir="ltr">Through this analysis, it was observed that three principle modes exist in stagnation point injection regardless of the injecting gas: a high frequency vortex-coupled mode, a low frequency Mach-shock-rigid mode, and a hybrid mode residing between these two modes. The first two modes were observed in all stability regimes, whereas the hybrid mode was only observed in the bifurcated regime. Furthermore, the unsteady regime was observed to be mostly characterized by this first, vortex-coupled mode. Conversely, the steady regime was observed to be driven by the Mach-shock-rigid mode instead. This transition was measured to occur as the thrust coefficient was increased.</p><p dir="ltr">This research also found that freestream noise resulted in an amplified and widened frequency range within the Mach-shock-rigid mode. This same freestream noise did not appear to have an impact on the other two principle modes; however, in some cases the noise produced in the Mach-shock-rigid mode due to this freestream noise did in fact mask the other principle modes.</p><p dir="ltr">Lastly, it was observed that the thrust coefficient, in and of itself, is not the sole indicator of stability in stagnation point injection. Across the different injected gases in this research, transition between the stability regimes did not in fact occur at a constant thrust coefficient value. Additionally, even within the same injected gas, this transition did not occur at the same thrust coefficient value between noisy and quiet runs—indicating an effect of freestream noise on stability.</p>

Of all children in the US born with Cerebral Palsy (CP), 30-40% of them will be diagnosed with Hemiplegic CP (HCP), presenting with one side of the body weaker than the other. The resulting asymmetries impede the ability of children with HCP to distribute weight evenly between their lower limbs. This often contributes to poor postural control and 'favoring' of their uninvolved side for stability during balance and gait. Much is still unknown about the biomechanical characteristics of asymmetry in the lower limbs. There are a few previous research studies completed in biomechanics labs that highlight some gaps in knowledge regarding our understanding of posture and balance in this population of children, but the availability of clinical assessments that help inform the implementation and impact of treatment targets for posture and balance are sparse. This dissertation showcases two independent studies aimed at some of the gaps in knowledge for posture and balance in children with HCP. The first study in this dissertation presents and tests the reliability when a clinical measure, the Posture and Postural Ability Scale (PPAS) was modified for use in children with HCP going through a therapeutic process. The PPAS was originally developed and tested with adults in controlled settings, often with individuals being placed in postures for examination. For the study presented here, modifications focused on scoring postures when children with HCP naturally assumed various sitting and standing postures during treatment. Researchers and an experienced therapist video-coded the modified PPAS. Intrarater and interrater reliability was calculated via Cohen's kappa, percent agreement and Intraclass Correlation Coefficients. Although reliability amongst and between researchers were weak (kappas < 0.7), videos were successfully scored, demonstrating the tool is feasible. In addition, some high levels of intrarater reliability was obtained by a more experienced clinician. Suggestive that this modified PPAS could serve as a potential tool for qualified clinicians to collect meaningful posture and postural control data. The second study addressed a specific gap in knowledge about the characteristics of gait anticipation (GA, i.e., expectation of initiating a step) in children with HCP on balance. Balance and limb symmetry metrics were compared during standing in three children with HCP and typically developing (TD) peers that were matched by age and sex, alongside a third (independent) sample of 12 unmatched TD children. Motion capture analysis and force plate technology were utilized to record and follow how center of pressure (COP) and center of mass (COM) move during quiet standing (without anticipating gait) and standing with GA. This study applied a Symmetry Index (SI) to COP displacement and COP velocity allowing for quantification of asymmetries between the lower limbs during standing with and without the anticipation of gait. Children completed multiple standing trials where they were ask to stand for 35 seconds (5 seconds to obtain balance and 30 seconds of data collection). Standing trials, involved sets where children were instructed that they would not walk forward and GA trials where they were asked to stand knowing that a light would indicate they should walk forward. The light also indicated which limb (i.e. right or left) the child should step forward with first. Limb designation for stepping forward was randomly generated. Data was examined across and within (15 second blocks) 30 seconds of standing. We had the following hypotheses: 1) GA would increase COP displacement and COP velocity for children with HCP greater than TD peers who would have no change; 2) children with HCP would have different levels of symmetry between the lower limbs when expecting to walk than TD peers; and 3) children with HCP would have different reaction times based on the limb (i.e., involved versus uninvolved) they were asked to start walking with. The HCP group showed the largest increase in COP displacement when comparing standing with no expectation of walking where they had an average of 22.0 ± 10.0 mm over 30 seconds of standing to an average of 24.5 ±9.90mm during GA. The matched group average was 11.3 ±8.87mm with no expectation of walking and 4.6 ±12.6mm with GA. The TD group's COP displacement remained relatively similar with an average of 8.04 ±6.40mm during when not expecting to walk and an average of 8.29 ±6.70mm with GA. Similar increases were seen for COP velocity. Comparisons for symmetry between limbs showed that COP was displaced more underneath the uninvolved side (first 15s was 79.52%) for children with HCP, and that COP displacement asymmetry switched to become larger underneath the involved side over time (the latter 15s was -82.81%) when there was no expectation for walking. This was inverted during GA, where children with HCP initially had more COP displacement on the involved side (-72.68%) and transitioned to higher levels on the uninvolved side (99.66%) as they prepared for gait initiation. Children with HCP took 0.2 seconds longer to initiate gait with their uninvolved (not preferred) side and also took twice as long to initiate gait overall in comparison to TD peers. Our data suggests that our listed hypotheses may be correct. However, this study has limitations to sample size, demographics and biomechanical metrics. Future studies should replicate these findings and include larger, more diverse samples with further metrics such as load. If findings are confirmed, this data suggests that therapies should consider that children with HCP might change postural strategies during standing when they are anticipating walking forward in comparison to simply standing in place. This dissertation seeks to set a foundation for collaborations between biomechanists and therapists alike, potentially highlighting novel opportunities to develop more innovative treatment options for children with HCP. / Doctor of Philosophy / Children with hemiplegic cerebral palsy (HCP) show limitations in coordination and activation of muscles on one side of their body; additionally, clinicians report an asymmetrical distribution of weight in their legs during standing and walking based on observation. This lower limb asymmetry is often paired with poor coordination and is believed to negatively impact posture and balance. Children with HCP often have difficulty starting and stopping walking, altered balance during sitting and standing, and challenges completing everyday activities such as navigating around or across obstacles and climbing up steps. I have worked together with my committee members to complete two independent projects measuring posture and postural control. The first project is a reliability study where researchers tested the utility of a modified measurement tool that could be used to score postures and postural control of children assuming natural postures during therapy sessions. The modified tool was based on a previously developed tool called the Posture and Postural Ability Scale (PPAS). The study had multiple researchers and a therapist score previously recorded treatment videos. Outcomes suggest that our modified PPAS could be used to score postures from video recordings of therapy session, but that increased modifications in the tool and scoring protocol are needed to improve the reliability of the tool. The second project funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development involved children with HCP and typically developing (TD) peers. The goal of the project was to understand if children with HCP change characteristics of standing when they know they will begin to walk. We also wanted to better understand issues surrounding how symmetrical (or not) children with HCP were with the use of both their involved and uninvolved legs. We found that children with HCP do alter characteristics of standing when they anticipate walking much more that TD peers. We also found asymmetries between the two limbs during standing that differed based on children with HCP's anticipation of walking.

Hovedproblemstillinga i denne undersøkelsen er ” Hvordan oppfatter musikk- og kulturskolelærerne den stille eleven og hvordan legger de opp gruppeundervisningen for å nå denne typen elever i gruppesituasjoner?” For å finne svar på dette brukte jeg kvalitativt forskningsintervju som metode. Fem strykelærere med minimum ti års fartstid og med erfaring fra både individuell- og gruppeundervisning har deltatt. Disse ble håndplukket fra mitt kontaktnett. Resultatet av undersøkelsen viser at lærerne ser på den stille eleven som en som ikke sier så mye og er veldig forsiktig. Utover dette kan det se veldig ulikt ut. For å nå den stille eleven kom det fram at det er viktig å arbeide med hele gruppa for å skape en fellesskapsfølelse, og at de som lærere ser og bekrefter elevene. I diskusjonen har jeg med utgangspunkt i teorier om gruppeprosesser og lederskap, diskutert hvilken betydning musikkundervisning i gruppe og hvilken rolle læreren har i forhold til den stille elevens atferd. / The main question in this survey is "What are experienced music and art teachers’ opinions on the quiet learner, and how do they reach this group of students in group teaching?" To answer this, I used qualitative interviews. Five string teachers with a minimum of ten years of experience and with experience in both individual and group teaching participated. The teachers were handpicked from my contacts. The results of the survey show that teachers see the quiet student as a person who does not say much, and is very careful. Beyond this, every quiet student can look very different. To reach the quiet student, it became apparent that it is important to create a group atmosphere, and that the teachers see and acknowledge the students. During the discussion, I have raised the importance of group teaching in music and the vital part the teacher plays, in relation to the development of quiet students, based on theories about group processes and leadership.

Football penalty kicks are having increasing influence in today’s professional game. Despite this, little scientific evidence currently exists to ascertain the mechanisms behind performance failure in this task and/or the efficacy of training designed to improve penalty shooting. In a football penalty kick it has been reported that the majority of kickers do not look to the area they wish to place the ball; preferring to focus on the ‘keeper and predict anticipatory movements before shooting. Such a strategy seems counterproductive and contradictory to current research findings regarding visually guided aiming. Coordination of eye and limb movements has been shown to be essential for the production of accurate motor responses. A disruption to this coordination not only seems to negatively affect performance, but subsequent motor responses seem to follow direction of gaze. Thus, where the eyes lead actions tend to follow. In study 1, ten participants were asked to kick a standard sized football to alternate corners of a goal, whilst looking centrally and whilst looking where they intended to hit. This disruption of eye-limb coordination brought about a 15% reduction in kicking accuracy. When participants were asked to fixate centrally, their shots hit more centrally (17cm) than when they were allowed to look where they intended to hit. These results were in spite of no significant differences between the number of missed shots, preparation time and ball speed data across conditions. We concluded that centrally focused fixations dragged resultant motor actions inwards towards more central target locations. Put simply, where the eyes looked shots tended to follow. The second study sought to test the predictions of attentional control theory (ACT) in a sporting environment in order to establish how anxiety affects performance in penalty kicks. Fourteen experienced footballers took penalty kicks under low- and high-threat counterbalanced conditions while wearing a gaze registration system. Fixations to target locations (goalkeeper and goal area) were determined using frame-by-frame analysis. When anxious, footballers made faster first fixations and fixated for significantly longer toward the goalkeeper. This disruption in gaze behaviour brought about significant reductions in shooting accuracy, with shots becoming significantly centralized and within the goalkeeper’s reach. These findings support the predictions of ACT, as anxious participants were more likely to focus on the “threatening” goalkeeper, owing to an increased influence of the stimulus-driven attentional control system. A further prediction of ACT is that when anxious, performers are more likely to be distracted, particularly if the distracter is threat related. When facing penalty kicks in football (soccer), goalkeepers frequently incorporate strategies that are designed to distract the kicker. However, no direct empirical evidence exists to ascertain what effect such visual distractions have on the attentional control, and performance, of footballers. In the third study, eighteen experienced footballers took five penalty kicks under counterbalanced conditions of threat (low vs. high) and goalkeeper movement (stationary vs. waving arms) while wearing eye-tracking equipment. Results suggested that participants were more distracted by a moving goalkeeper than a stationary one and struggled to disengage from a moving goalkeeper under situations of high threat. Significantly more penalties were saved on trials when the goalkeeper was moving and shots were also generally hit closer to the goalkeeper (centrally) on these trials. The results provide partial support for the predictions of attentional control theory and implications for kickers and goalkeepers are discussed. The previous studies showed that anxiety can disrupt visual attention, visuomotor control and subsequent shot location in penalty kicks. However, optimal visual attention has been trained in other far aiming skills, improving performance and resistance to pressure. In study 4, we therefore asked a team of ten university soccer players to follow a quiet eye (QE; Vickers, 1996) training program, designed to align gaze with aiming intention to optimal scoring zones, over a seven week period. Performance and gaze parameters were compared to a placebo group (ten players) who received no instruction, but practiced the same number of penalty kicks over the same time frame. Results from a retention test indicated that the QE trained group had more effective visual attentional control; were significantly more accurate; and had 50% fewer shots saved by the goalkeeper than the placebo group. Both groups then competed in a penalty shootout to explore the influence of anxiety on attentional control and shooting accuracy. Under the pressure of the shootout the QE trained group failed to maintain their accuracy advantage, despite maintaining more distal aiming fixations of longer duration. The results therefore provide only partial support for the effectiveness of brief QE training interventions for experienced performers. This series of studies are the first to explore the gaze behaviour of football penalty takers in a quest to uncover and understand anxiety’s negative influence on attentional control and performance. They are also the first to explore the efficacy of goalkeeper distractions and training in improving performance from both the goalkeeper’s and kicker’s perspective. The results of these studies conclude that when anxious, penalty takers show an attentional bias toward the ‘threatening’ goalkeeper that can be increased and utilised by a goalkeeper employing distraction techniques and that penalty takers do benefit, to some extent, from a gaze-based pre-shot routine

Depuis 2002, la directive européenne 2002/49/CE demande aux grandes villes de définir des zones calmes dans leur P.P.B.E. (Plan de Prévention du Bruit dans l'Environnement) dans le but de les préserver. L'utilisation de l'indicateur acoustique Lden est suggérée mais les états membres sont libres d'en proposer d'autres. Afin d'aider les autorités en charge de l'application de cette directive, ce travail de thèse propose une approche multidisciplinaire pour mieux définir cette notion de zone calme en milieu urbain. Une étude historique du mot calme a été réalisée à travers un corpus de dictionnaire du XVIe siècle à nos jours, pour mettre en évidence les différents sens rattachés à ce mot. Il est apparu que le lien vers le domaine sonore est tardif. De plus, la notion de calme est relative ce qui la différencie de la notion de tranquillité. Pour faire émerger les représentations actuelles, des ateliers de concertation ont été réalisés à Cergy-Pontoise et Paris. Ces deux approches ont permis de proposer des critères de caractérisation des zones calmes. Une enquête de portée nationale a ensuite été menée. Elle a permis de révéler 3 types de points de vue partagés par différents groupes de population. Pour certains, une zone calme est une zone de partage, pour d'autres une zone calme est un espace naturel et pour les derniers, une telle zone doit être silencieuse. La notion de contraste qui a émergé tout au long de ce travail a été étudiée plus en détails, à partir de test d'écoute en laboratoire et à partir des cartes de bruit. Un indicateur de contraste inspiré de la détection de contours en analyse d'image a été proposé. / Since 2002, European directive 2002/49/EC asks big cities to define quiet areas in order to protect them. The use of Lden indicator is suggested but member countries are free to suggest others. In order to help authorities in charge of directive application, this PhD work proposes a multidisciplinary approach to better define the quiet area notion in urban context. An historical study of the “calme” word was carried out through a dictionary corpus from the sixteenth century to nowadays to highlight the different meanings of this word. It appeared that the link to the sound field is late. Moreover, calm notion is relative what differs of tranquility concept. To highlight current representations, workshops with inhabitants were carried out in Cergy-Pontoise and Paris. These two approaches allow us to propose criteria to characterize quiet areas. Then, a national survey was conducted. It allowed to reveal 3 types of points of view shared by different groups of people. For some, a quiet area is a sharing zone, for others, a quiet area is a natural area and for the lasts, such area must be silent. The contrast notion that emerged throughout this work has been studied in more details, using listening tests in laboratory and, using noise maps. A contrast indicator inspired from edge detection in image analysis was proposed.

The increasing number of electric and hybrid vehicles in urban areas has shown to be beneficial in reducing both air and noise pollution. However, the lack of sound when driving at low speed has negatively affected the pedestrian safety since many rely on the vehicle sound for orientation. Regulatory bodies have therefore introduced minimum sound requirements for all silent vehicles, which has resulted in a key challenge for car manufacturers to develop external warning signature sounds. The objective of this project has been to study how these signals should sound in order to fit the image of electric and hybrid vehicles and minimize noise and annoyance. To complete the study, five sound concepts with different characteristics and rhythms were developed using the concept generation process. In order to gain subjective impressions of the sounds, three measurement methods were utilized. The first listening test was performed to eliminate the possibility that the sound samples would be perceived variously loud in the upcoming tests. The second listening test was performed to gain information on how suitable the signals are for electric and hybrid vehicles, and the third listening test was conducted to obtain information on how much annoyance the signals contributed with. A reference signal representing an internal combustion engine was included in the tests as well. The results of the measurement methods showed that the sound samples with long tone sequences were more preferred than those with short tone sequences, and that the artificial approach was more popular than the sound of an internal combustion engine vehicle. It was also established that additional tests need to be performed in order to confirm that these results are valid. It was suggested that field tests should be conducted and that new sound concepts should be developed based on the results of these tests.

I min uppsats fördjupar jag mig i arbetet kring de som i allmänna ord benämns för blyga barn. Vad innebär det egentligen att vara blyg, är det ett personlighetsdrag som är svårt att ändra på, eller ett tillstånd som behöver bearbetas för att nå utveckling? Eller kan det rentav vara något som är ärftligt och därmed inte påverkbart? Vad innebär blyghet i förskolan för barnet och pedagogen och hur kan pedagoger lyfta de barn som inte syns eller hörs. Är det överhuvudtaget något att oroa sig över och isåfall vad kan man göra för att stötta de blyga barnen i deras fortsatta utveckling. Genom att använda mig av sociokulturella och normkritiska perspektiv försöker jag tolka hur dessa två aspekter påverkar synen på blyghet. I denna uppsats utgår jag från mina egna erfarenheter för att i efterhand reflektera över hur min egen syn, förskolans och samhällets syn påverkar oss i det dagliga bemötandet. / In my essay I try to get a better understanding of those who in general words are called shy children. What does it really mean to be shy, is it a personality trait that is difficult to change, or is it a condition that needs to be processed to further development? Or could it perhaps be something that is hereditary and thus impossible to affect? What exactly does shyness mean in the preschool for the child and the teacher, and how can the teachers try to reach children who are not usually seen or heard. Is it at all something to worry about, and if so, what can you do to support them in their continued development. Through the use of different perspectives such as the socio-cultural and norm-critical, I try to see how various aspects influence the view on shyness. In this essay, I use my own knowledge and previous experiences in order to reflect on how my own, the preschool and society's view affects us in the daily approach.

Para sistematizar a produção, majorar a produtividade, suprimir gastos e economizar tempo, empresas aderiram ao telemarketing, principal atividade terceirizada no Brasil e uma das maiores empregadoras do país (665 mil teleoperadores). Todavia, doenças desencadeadas pela atividade laboral são freqüentes em teleoperadores, fato que tem motivado empresas a buscarem recursos no próprio ambiente laboral, como a implementação de uma sala de descanso para seus funcionários, para atender ao recém aprovado Anexo II, da Norma Regulamentadora 17, que instituiu a obrigatoriedade da realização do intervalo para refeição/descanso fora do posto de trabalho. O presente trabalho teve por objetivo verificar, junto a teleoperadores e supervisores de telemarketing, o uso da sala de descanso implementada na empresa e suas opiniões sobre a relação entre uso e afastamentos por motivo de saúde, promovendo uma intersecção entre Psicologia Ambiental e Direito Ambiental do Trabalho. Realizou-se, primeiramente, um estudo piloto com 15 teleoperadores (10 mulheres e 5 homens) e 1 advogado da empresa, resultando em algumas alterações no questionário para teleoperadores. Participaram da pesquisa, fora do ambiente e expediente de trabalho: 80 teleoperadores (48 mulheres e 32 homens), 56% entre 18-25 anos; 73% solteiros; 59% do turno manhã/manhã-tarde; 74% sem ou cursando nível superior, sendo 39% de indicações de ensino médio completo e 35% de ensino superior incompleto; 56% iniciaram na atividade de telemarketing entre 2004-2007 e, nesse mesmo período, 60% ingressaram nessa empresa em que atualmente trabalham; e três supervisores de telemarketing do sexo masculino, entre 26-28 anos, nível superior completo, turno M/M-T, dois solteiros e um casado, contratados entre 2000-2001. Evidenciou-se que: (1) tanto teleoperadores (97%) como supervisores (100%) consideram a atividade parcialmente ou plenamente estressante; (2) durante as curtas pausas, a maioria freqüentemente permanece no refeitório (teleoperadores 71%, supervisores 100%); (3) seja antes (50%), durante (43%) ou após o expediente de trabalho (74%), a maioria nunca utiliza a sala de descanso; (4) relaxamento (41%) e interação (teleoperadores 31%, supervisores 100%) são as atividades mais realizadas pelos teleoperadores, quando do uso da sala; (5) cerca da metade dos teleoperadores (53%) nunca se afastaram, embora 75% dos supervisores indicassem certa freqüência de afastamentos na empresa, porém 60% dos participantes entraram na empresa entre 2004-2007; (6) a maioria atribui fatores positivos à sala (76%) e acredita em sua influência na saúde e bem-estar (teleoperadores 84%, supervisores 75%); (7) 67% dos teleoperadores e 100% dos supervisores julgam necessário ou relevante a implementação de políticas de saúde na empresa, para estimular o uso da sala de descanso e reduzir afastamentos por doenças ocupacionais. Em suma, os resultados evidenciaram o não uso dessa sala de descanso por diversos fatores (ambientais, cultuais, sociais e econômicos), embora os participantes a considerem relevante para a questão da saúde do trabalhador, sugerindo a necessidade de se repensar este espaço, bem como a organização do trabalho, observando-se as sugestões dos participantes apontadas neste estudo, como recreação e interação, atividades que se contrapõem às características rígidas e penosas do telemarketing. (CAPES/CNPq) / To systematize the production, increase productivity, eliminate costs and save time, companies has joined to telemarketing, the main activity outsourced in Brazil and one of the largest employers in the country (665 thousand teleoperators). However, occupational diseases are common in this context, motivating firms to seek resources in this own workplace, such as the implementation of a quiet room for its employees, to mut the newly approved Anexo II, of the Norma Regulamentadora 17 (rule), wich established the obligatory completion of break for meal/rest off workplace. This study aimed to check, next to the teleoperators and supervisors of telemarketing, the use, for teleoperators, of the quiet room implemented in the company and its opinions about relation between use and removal for reason of health, proposing an intersection between Environmental Psychology and Enviromental Labour Law. There was a pilot study with 15 teleoperators (ten women and five men) and a lawyer of the company, resulting in some changes in the final questionnaire for teleoperators. Participated on the survey, out of the company and expediency of work, 80 teleoperators: 48 women and 32 men; 56% between 18-25 years; 73% single; 59% of the turn morning/morning-late; 74% without or taking higher level, with 39% of indications of complete average education and 35% of incomplete higher education; between 2004-2007, 56% had started in the activity of telemarketing and 60% joined the company in wich they work. Three male supervisors had also participated, between 26-28 years, higher level complete, turn morning/late-morning, two singles and one married, recruited between 2000-2001. The results showed no significant differences between the teleoperators (sex/shift of work) and had showed that: (1) 97% of the teleoperators and all the three supervisors had considered the activity partially or fully shessful; (2) during short breaks, 71% of the teleoperators had indicated the frequent use of the cafeteria, also indicated for the three supervisors; (3) the majority of the teleoperators never uses the quiet room, either before (50%), during (43%) or after hours of work expedient (74%); (4) when the use of the room, activities were held more relaxing (indicated by 40% of the teleoperators) and interaction (indicated by 29% of the teleoperators and two supervisors); (5) 54% of the teleoperators has never moved away for health reason, however two supervisors had indicated frequent removals and one, sometimes; (6) 84% of the teleoperators and two supervisors had indicated the influence of the use of the quiet room in health; (7) 67% of the teleoperators and all the supervisors had judged necessary or relevant the implementation of politics of health in the company, to stimulate use of the quiet room and reduce injuries by occupational diseases. In conclusion, although the results showing the non-use by teleoperators of the quiet room, which had the many factors (environmental, personal, cultural, social, economic, etc.), the participants had considered it excellent for the health of the worker, suggesting the need to reflect about this space and the organization of the work, in compliance with the suggestions of participants, such as the need for recreation and interaction, activities no common on the rigid and heavy context of telemarketing.
