The present dissertation describe the studies conducted on the synthesis and photophysical properties of phthalocyanine dyes. The main propose of this work was to produce amphiphilic structures with low aggregation in solution. These properties are relevantfor photodynamic therapy (PDT) applications. The first synthetic methodology involved the preparation of two phthalonitriles which were previously prepared in our research group (3 and 6) (SCHEMES 1 and 2). Phthalonitrile 3 was synthesized from anhydride 1 by conversion to its corresponding tetraimide and subsequent transformation into the desired compound 3... (continue)

This dissertation was written in the form of a compendium of six scientific texts, which are articulated in order to discuss the impacts of partner physical violence on mother-child relationship. The first two papers present literature reviews. The first one revieweb the impact of domestic violence on mothering skills. The second one, the association between intimate partner violence and child maltreatment, two phenomena commonly associated, but which are commonly analyzed separately. The third paper aimed at comparing the dimensions of discipline practices of mothers victims and not victims of physical partner violence. The fourth article sought to examine the motherchild relationship in a situation of controlled observation laboratory, to investigate the specific impact of partner violence on the mother-child interaction. The fifth paper presents a review of a new cognitive construct to analyze the mother-child relationship, metaparenting, and the state of art about such constructo. Finally, the sixth paper compares the behaviors of metaparenting of female victims and not victims of physical violence. Overall, the data indicated that, when compared in relation to dimensiono of discipline and metaparenting, mothers victims of domestic violence and mothers without such a history, did not show statistically significant differences. When analyzing the impact of different variables on the mother-child relationship (Article 4), it was noted that the historical mother of child maltreatment and family income appear to be important variables to consider when analyzing the mother-child relationship.

This thesis approaches an ordinary practice by the State: public homages, like medals of honor, honorific titles and denomination of public areas. From an ethnographic research of three municipal Legislative Councils, the dynamics of these homages, the actors and factors involved were investigated. It was observed both the bureaucratic and "political" aspects of such homages. An important characteristic of these processes is that they are treated by the politicians themselves as an irrelevant assignment. However, the ethnographical data shows that these activities constitute the majority of projects presented by the council-men. In the interviews granted by council-men, officers and NGO´s members that "observe" the politicians, central terms to think about these practices, such as agreement and blandishment were noted. These terms seem to show a way of interpretation for the high number of homages. There is a pre-established agreement in the Councils to let the homages pass, because they are usually approved as blandishments to a potential or actual electorate. This thesis tries to show the subtleness and the details involved in such cases of public homag.

The goal of this work was describe and interpret the representation that prosecutors, judges and defenders of adolescents who engaged in illegal acts, and the rationalization process of the judiciary, specifically the Court of childhood and adolescents. The cases involving children in conflict with the law from 1970 to 2008, which are on the file of the county court of Rio Branco, at Acre state, have been studied. The cases were divided into four periods within which three laws has operated: in the first period of the 1970s, the Code Mello Mattos of 12 October 1927 was in force (Decree No. 17 943 A), which lasted until 1979; in the second period, the 1980s, the Juvenile Code (Law 6697 of 10/10/79); and after 1990, when the Statute of Children and Adolescents (Law 9.069/90) was enacted, two periods were studied: the third period comprises the years between 1990 and 2005, shortly after the SCA entered into force; and the fourth period, between 2006 and 2008, when the SCA had been in effect for over fifteen years. Having available for research processes within a period of nearly 40 years, it was possible to conduct a study of the changes which have happened in the representation and in the process of rationalization. It was observed that rationalization was higher each period. The representations, which were expressed in judgments and opinions, were easily identified in the cases from the 1970s, and have been becoming more difficult to be detected as the process of rationalization has made the judgments and opinions more objective, impersonal, and technical. There are no opportunities for judges, prosecutors and defenders to express their thoughts and personal opinions. Thus the representations are expressed in the laws, and are then assumed by the operators of the law, namely judges, prosecutors and defenders.

The present work investigated high school students about the elaboration of conceptual maps and the resolution of their problems related to the topic intermolecular interactions. For that we based upon Ausubel's theory of meaningful learning, Concept Maps and troubleshooting. To carry out this research we use the elaboration of Concept Maps using a list of concepts extracted from their problems and that are relevant to their resolution, and the construction of the "Reference Map" according to the proposal of Joseph Novak. To make the maps the students organized hierarchically the listed contents and in accordance with the principle of progressive differentiation we determined the major conceptual deficiencies. The resolution of the problems constituted another tool for the cognitive mapping, as the students show how the concepts are organized in their minds through the application in solving the problem. The results obtained with the conceptual maps were used to trace the cognitive structuring and compared to analyzes of the resolutions of problems determining qualitative and quantitative aspects in relation to structuring and conceptual similarities in results between the two instruments. It was determined the Pearson s correlation between the results of the maps and the resolution of problems, resulting in a weak correlation between the two instruments. The reason for this is not conclusive in the extent of this research and relevant discussion originates later works. Qualitative analyzes show that the two instruments are able to determine cognitive structuring concepts and indicate their shortcomings.

to teach and the importance of the teacher to keep learning are highlighted themes in order to comprehend the professional development and the teacher s education, although the aspects of caring and educating are still disconnected when we think about the pedagogical practices in kindergarten. Considering this, a qualitative approach of researching was adopted in three municipal kindergarten educational centers in the countryside of São Paulo, involving three beginner teachers, who work with children from zero to three years old. Considering the research question How is the beginning teachers` teaching knowledge configured to act in nursery care? , we tried to characterize the knowledge owned by the teachers who work with children from zero to three and how they learn to be nursery care teachers. In order to develop this study, field observations, diary registers, documental analyses and semi structured interview were undertaken. The collected data were organized in five axes of analyses in order to achieve the research s specific objectives: a) the teachers´ conception of nursery care and children; b) the kindergarten institutions´ pedagogical propose; c) the actions of educating and caring; d) the contents taught to children from 0 to 3; e) the learning of teaching in the nursery care. The analyses according to authors as Abramowicz, André, Cerisara, Bondioli, Faria, Garcia, Huberman, Lüdke, Mantovani, Nóvoa, Oliveira, Rosemberg, Tardif, among others, show that teachers are not able to name the knowledge they own, but they know what to teach the children and know where to find activities to be executed with them. Generally speaking, the teachers outlined the importance of executing an educative work and a necessary care of these children. Concerning the nursery care undertaken activities, the teachers reported they are not organized according to the contents. But concerning the degree of difficulty and the intentionality, which guides the age level of the nursery care children, the demands must be according to the child s development and the child´ s age specificity. A common aspect in the three teachers´ speech refers to the knowledge acquired in the professional practice by the exchange of knowledge with more experienced teachers, the main source of learning to teach in the nursery care.

In contemporary marketing structure notices the growing quest for competitive advantage of organizations. In this context, we highlight the performance management that can assist in the search for competitiveness and dairy industry marked by specificities to produce and offer products with quality and consumer safety. To achieve this success, dairy rely on performance measurement systems to assist in its production process, management and distribution of products. Being that there are factors that can shape the use of performance measurement. From this backdrop, this paper aims to examine the prospect of multicase, the internal and external factors affecting the use of performance measurement in dairy industries in Sorocaba-SP. The relevance of this research proposal is to contribute to the theoretical aspect in the development of knowledge about performance measurement and practical aspect to making a diagnosis of the factors that influence the performance measurement in the dairy study, resulting in a major material for understanding and improving the everyday reality of collaborating companies. To develop this study, we carried out a field survey with managers of three quality dairy products in Sorocaba-SP. It is used as a research tool, a semi-structured, with a qualitative approach, aiming at deepening the knowledge about a given reality. Factors identified with exploitation cases were internal factors: organizational culture, management style, organizational structure, competitive strategy, resources and capabilities, IT infrastructure and external factors: integration between the different links in the chain and government regulations (IN62 ).

Aluminium alloys of the 7000 series are widely used in structural components in the aircraft industries due to their high strength and low density. However, a large amount of scraps is generated by the machining of the components, which achieves almost 90% of the alloy s initial mass. These wastes are normally used in low performance application, despite of the high quality of the AA7050 alloys. It occurs because is not possible to keep the good mechanical properties of the alloy when it is recycled by conventional casting, which generates high level of segregation of the alloy elements and a coarse microstructure. In this sense, the present work aims the recycling of the aluminium scraps by spray forming and hot extrusion. The spray forming process provides a rapid solidification, making possible to obtain a refined microstructure and a low level of segregation. The hot extrusion closes the pores arising from the previous process and increases the strength by reducing the grain size. After the spray forming the material was hot extruded in a industrial scale equipment in order to close the pores arising from the previous process and improve the strength. A combination of heat treatments concerning homogenization, solution and aging heat treatments were imposed during the process in order to optimize the mechanical properties. The microstructure characterization was carried out in a scanning electronic microscope (SEM) and in a transmission electronic microscope (TEM), combined with x-ray diffraction (XRD) and differential scanning calorimetry (DSC) . The mechanical properties were evaluated by tensile tests. By the analysis of the results we can conclude that the spray forming is a viable route to recycle the Al AA7050 alloys because it can generate refined microstructure and better mechanical properties than the original material.

Refractory masses for lost wax casting process of steel and alloys, especially for dental devices are constituted basically of silica (quartz and / or cristobalite). In these materials, the binding agent is generally based on magnesium phosphate cements, produced by acid-based reaction of NH4H2PO4 with MgO. The main product of the reaction is struvita (MgNH4PO46H2O). The presence of phosphates together with retarders, necessary to control the reaction kinetics, contributes to the sintering and adhesion of the silica investment to the metal material after solidification. Recently it was developed a consolidation process of ceramic powders by direct coagulation (DCC) of a stabilized slurry of high solids content and low viscosity. The direct coagulation is achieved by controlled destabilizing (flocculation/ coagulation) of the suspension either through the gradual change of the pH towards the isoelectronic point or increasing the ionic strength of the medium. In this work the change in pH was accomplished by two different routes. The first one by the use of buffer solutions whose pH controll was close to the one of silica IEP (innovative methodology). The second was made by using citric acid and sodium trypolyphosphate in a competing reaction changing slowly the medium pH towards the silica IEP. Both routes promoted the direct coagulation of silica refractory masses without the presence of phosphates or any other binder. The results were very satisfactory, since in all silica refractory masses (>99% SiO2) used, the coagulation occurred rapidly, at low initial viscosity, and low final water content to be eliminated. The masses kept the required refractory properties for high temperature castings, presenting excellent properties such as high expansion at the metal casting temperatures, excellent surface finishing, low adherence to the cast part and easiness upon demolding. This whole set of properties are ideal for lost wax investment casting processes.

The discovery of the Human immunodeficiency virus (HIV) during pregnancy drives woman to experience prejudice, discrimination and the possibility to infect her child, promoting an existential reflection. Suffering is present, conducting to a hope experience. Hope is a dynamic and multidimensional process, focused in the possibility to achieve what is desired. Incorporate bases and force to exist, being reached in the moments of difficulty. Therefore, the routine with HIV during pregnancy connect itself to the experience of hope, for that reason the present study has hope as its component. The objective was to explore and describe hope experiences during pregnancy of woman that discovery her HIV seropositive at prenatal. This study had as theoretical reference the Symbolic Interactionism and narratives research as methodological reference. The strategy to data collection was semi-structured interview associated with hope s genogram and ecomap. It was part of this study seven pregnant women who discovered their HIV seropositivity during prenatal. The results are present and organized in the following thematic units: Life review ; be a mother , care of herself , surrender to divine intervention , social interaction and hope . The main phenomenon identified was fight against the lack of hope . It was conclude that the tendency to lack of hope is strongly present in the gestational routine of these women and that exist interactions that are hope promoters and others that restrict it. Woman try to valorize those that are hope promoter to reach what It was established as a goal in that period: contribute with her child s seronegativity.

In this work we seek to observe the discursive representations of contemporary reading practices. In view of the technological changes that have been presenting since the end of the 20th century, which configure what has been called digital culture, we seek to observe the impact of the strength of this culture on contemporary writing and reading practices. To this end, we define as an object of analysis the literary mashups, which are the result of a culture of the mix of today's own mix. This practice of mashup, quite common in relation to other artistic languages, such as music, has developed in relation to texts, and presents itself as an interesting change in writing and reading practices nowadays. In order to understand some of these mutations, we raise some discursive representations present not only in the texts produced according to the practice of mashup, but also those apprehensive through the polarization of discourse about this recent editorial phenomenon. We will constitute our corpus with two copies of mashups of Brazilian classical literature, namely, Dom Casmurro and the Flying Saucers and The Alienist Hunter of Mutants, both originating from the works of Machado de Assis. Thus, we will observe what are the linguistic and stylistic choices that define the degree of maintenance or change of narratives. We also seek to highlight the discursive formations for and against the practice of mashup. To undertake this analysis, we focus on the articulation between the assumptions of the Cultural History of reading as presented by Roger Chartier (1999) and on the concepts of French Discourse Analysis, mainly on the work of Michel Foucault (2008; 2009). Observing such changes that occur in the linguistic structures of the text, as well as in the manifestations of readers regarding the editorial dissemination of these books (from comments on blogs), we seek to discuss the principle that governs the appropriation of the editorial market of this mash-up practice, based on the assumption that it began with the spontaneous production of remixes, and that today it offers itself as an editorial line of some publishers that focus on the consumer market for children and youth.

This research has focused on exploring the possibilities and limitations of a WebQuest as an educational tool implemented to cover different topics of Organic Chemistry related to plague insects and their biological control in crop management, Controle Bioracional de Insetos Praga (CBIP), a research program linked to the National Institute of Science and Technology (INCT) at UFSCar. This case study dealt with the controversial socioscientific issue that represented the control of fall armyworm (Spodoptera frugiperda) which caused damage on local corn crops, and was performed by a high school class in the Junqueira Educational Center, located in Morro Agudo, SP. The relationships among science, technology and society (STS) and central dimensions to make decisions regarding the addressed problem, as well as the learning possibilities offered by the WebQuest could be understood in a broader context. In order to evaluate the student s performance, their whole textual production towards the resolution of the problem was considered (questionnaires, reports, power point presentations etc.), exposing the alternatives found for this particular plague control in corn crops (mechanical, biological and chemical methods), pretending for that matter to be a fictitious company responsable for the optimization of its corn production. It was possible to verify that the students previously divided into three groups managed this particular task successfully which required analytical and scientific judgement.

The precarious nature of brazilian logistics infrastructure, technologically outdated, has been facing with a scenario marked by food global demand increase, a fact that may reflect in the country's economic development delays. Considering the important Brazil agribusiness nature and the participation in agricultural production expansion opportunities, it is necessary that national forces both public and private assess the possibility of performing logistical adjustments, so that the country can align its production capacity with the international consumption agribusiness demands In addition, it may be noted that, in 2011, logistics represented 10,6% of the national GPD (Gross Domestic Product), also considering that transport and storage stand out as factors that have an important influence over supply chains dynamics. In grain production chains, these logistics activities may involve intermodal terminals that may be suitable for storage and transhipment of these grains. The Southeast region plays an important role in grain production and handling processes in Brazil, distinguishing by its grain productivity (kg/ha) in 2011/2012 season, second only to the South in the 2010/11 season. Thus, this study aims to investigate Southeast intermodal terminals performance checking their levels of efficiency in brazilian grain harvest flow logistics operations. The research approach was defined as qualitative and quantitative or mixed with exploratory purposes. The research method was the case study (multicases) and data collection was conducted through interviews, using a structured questionnaire and nonprobability sampling, for convenience. Initially, the process was carried out to characterize the terminals, through the establishment of the frequency distribution and then, quantitative data were evaluated from Data Envelopment Analysis (DEA) technique. The application of both models of Charnes, Cooper and Rhodes (1978) constant returns to scale BCC - and Banker Charnes and Cooper (1984) variable returns to scale CCR - showed that only three (4, 7 and 11) of the twelve analyzed decision making units (or terminals), also known as DMUs, have got overall technical efficiency, ie, can use their inputs efficiently, without incurring on huge wastes. In addition, these terminals are the only ones with pure technical efficiency. On the other hand, the three inefficient DMUs (1, 2 and 12) showed pure technical efficiency, suggesting that these terminals could present presumable scale operation inefficiency, an aspect not addressed in this paper. The logistics terminals analysis allowed the understanding of the grain movement context from the brazilian intermodal transport perspective as well as iv it was possible to verify that a greater operational productivity can be obtained regarding the use of the structure and resources available.

Over past years, in the period of greatest rainfall - between december and march the cities suffer from floods. There are various motives for the urban floods, including the changes in the hydrological cycle and the disordered process of urban land use and occupation. Floods cause impacts to the population subject to the phenomenon, whose mitigation is fundamental and is based an action that balances urban development with environmental conditions. The present work aims to identify the main factors which act directly or indirectly in floods from the perspective of the areas vulnerable to flooding, with case study in the city of Sao Jose do Rio Preto-SP. From the analysis of the literature review were selected four parameters related to the areas vulnerable to flooding: the use and occupation of urban land, the river basin, the urban drainage, and the vulnerability. A method of evaluation of areas with the main features to be parsed assigning scores to the same, with the intention of quantifies and qualifies them. As a result were obtained a diagnoses form the selection area with their respective scores, degree of vulnerability, recommendations and suggestions, as well as map overview and representation schematic of the area.

Brazil is the world's largest producer of sugarcane and the leading exporter of its derivatives (sugar, alcohol, energy etc.). One of the main waste generated in the manufacturing process of this sector is the sugarcane bagasse ash sand (SBAS), produced from the burning of bagasse into boilers to produce electricity (cogeneration). This ash sand is composed of a high amount of silica and it is also currently discarded in cane plantations as organic fertilizer, despite the fact that it is poor in nutrients. This research proposes to provide an alternative application of SBAS in concrete as a replacement material for fine aggregate. Furthermore, the durability of concrete with alternative materials demands a special attention, especially regarding reinforcement corrosion. This is a major concern of the use of wastes on the degradation of concrete structures. The process begins with the despassivation of steel reinforcement, and it propagates in a suitable environment. The aim of this study was to evaluate the potential occurrence of reinforcement corrosion in concrete made with SBAS as a partial replacement material for fine aggregate. The ash sand samples were collected in a plant in the State of São Paulo, and standardized through a sieving and grinding. The SBAS was subjected to physical and chemical characterization, by its chemical composition, sieve analysis, powdery material, absorption, bulk density and true density. Mortars and concretes were produced with levels of substitution of 0% (reference), 30% and 50% of SBAS. In mortars, tests of compressive strength, porosity (void index and pores analysis by optical microscopy), water absorption, accelerated carbonation, chloride penetration and electrical conductivity of the aqueous solution were performed. The concretes were submitted to tests of compressive strength, void index, absorption, chloride penetration, potential and rate of reinforcement corrosion. Thus, the results indicated that substitution of 30% and 50% by SBAS can increase the compressive strength of concrete and the resistance to attack by chlorides, and decrease the despassivation probability of reinforcement. However, with the content of 50% of SBAS, the corrosion rate was significantly higher in comparison to other samples, and it was similar between the concretes with 30% of SBAS and reference. Thus, it was possible to conclude that the concrete with 30% of SBAS as a substitute of fine aggregate may be applied in conventional structural elements without loss of mechanical and durability performance.

The emergence of new technologies and process automation of libraries and information centers open new possibilities for studies of uses and users within these environments. The aim of this study was to know the users' reading behaviors and how these behaviors are related to each other, based on records from the library home loans. The research method was the case study, the unit should the Community Library of Federal University of São Carlos, São Carlos campus. The techniques used was the analysis bibliometric of information and analysis of social networks, with support from VantagePoint® software. The data sample analyzed comprised 119,720 records related to the circulation (borrowing, renewal and reserves) of the collection in 2011. The results were prepared and analyzed indicators on the use of the acquis by the community: 1] Indicators related to movement; 2] Indicators on lending activity; 3] Indicators on lending activities of the Literature; 4] Indicators on the lending activities of the collection of Library and Information Science; 5] Indicators on renovation activity, and 6] Indicators on the activity of booking. Based on the obtained results it can be stated that the use of bibliometrics for conducting user studies predicted by the theory of studies of uses and users, was efficient in developing a set of indicators for the profile of users and uses of the collection, in an automated method and without direct contact with users. It was also possible to reaffirm the importance of studies of uses and users through a quantitative approach with new information technologies that open up new possibilities for this type of study.

La difusión y proliferación del uso didáctico de ordenadores conectados a Internet han proporcionado un nuevo contexto de acción para los profesores de idiomas. En este nuevo panorama, las clases en el aula no consisten en el único espacio de interacción de los cursos y muchos profesores utilizan también Entornos Virtuales de Enseñanza- Aprendizaje (EVE/A) como apoyo y complementación al trabajo que desarrollan en la modalidad presencial. En rechazo a la práctica de transponer el modelo de enseñanza presencial a los medios digitales, los expertos sugieren que la adopción de nuevas tecnologías en el aula debe basarse en prácticas pedagógicas apropiadas a este contexto (KENSKI, 2008; SILVA, 2003). El interaccionismo social de Vigotsky (1988) se encuentra en la base de la pedagogía de la enseñanza ministrada en entornos virtuales de enseñanza-aprendizaje por defender que la construcción del conocimiento está condicionada a la mediación social - que, a su vez, ocurre a través de la lengua en interacción. Esta investigación se centra en el estudio de las interacciones que ocurren en los foros en línea de un curso de Español para Turismo - ofrecido en la modalidad a distancia en el entorno virtual Moodle. Su objetivo es problematizar la influencia de los andamios (WOOD, BRUNER, ROSS, 1976) en la construcción del conocimiento en lenguas extranjeras. Esta es una investigación cualitativa y interpretativa, cuyos análisis se basan en estudios sobre la interacción en foros en línea (PAIVA y RODRIGUES JR., 2004; LUCENA FILHO y OLIVEIRA, 2006; GREGOLIN, 2008) y sobre la enseñanza mediada por nuevas tecnologías (KENSKI, 2008; BARBERÁ, 2006). Nuestro objetivo fue comprender el funcionamiento de los foros, delimitando los tipos de andamios más recurrentes y sus funciones en el contexto de un curso de español para el turismo. También se buscó, a través de la investigación, aportar datos que puedan contribuir en la formación de profesionales capaces de actuar en el escenario educativo que se define a partir de la masificación del uso de las nuevas tecnologías. Los resultados mostraron un amplio uso de ayudas pedagógicas o andamios por el profesor y por los propios estudiantes, lo que explicita el papel fundamental de los foros en línea como un lugar de socialización y nos permite concluir que la educación virtual basada en la interacción es capaz de impulsar el desarrollo de los aprendices en la construcción de conocimiento en lengua extranjera, potencializando los espacios de interacción de los cursos.

This dissertation aimed to understand the relationship between public school and democracy, mediated by democratic management, the perspective of school managers, believing that democratic development in society comes through participation spaces, with decisions. It reflected on the importance of democracy and its significance in the context of school relations, taking into account that it is an epistemological problem as much as a political enigma seizing axes articulators of public policy. Had the mainspring three concerns: the extent to which the managers interviewed established democratic practices in school management? In what areas? How these practices were considered democratic, and how they strengthened? In the empirical part we selected a city located in São Paulo, midsize, called Rio Claro. It set up a sample of ten managers, with whom semi-structured interviews were conducted. Presented a study on democracy, from the economic, political and social that characterize modernity, with reflections on modern liberal democracy; Theory of Communicative Action and the transformations that characterize modernity, according to Jurgen Habermas, and a panorama of relations that characterize the formation of the state and of Brazilian politics. It was understood that the managers interviewed were creating democratic practices in school management, to stimulate dialogue and hosting, while listening demands, respect for differences, singularities and interests in the school daily, to share decisions and responsibilities to respect the limits of the functions and duties of a member in the hierarchy of the workplace, to pursue work together, the use of "instruments" as simple questionnaire for families of students, the flexibility of schedules to attendance of parents and family, participation and training partnership between school and family for the benefit of students, the collective construction of PPP as an approximation between the school and community. These actions allowed us to understand how managers understood to be enabling democratic practices in school, the school administration and school linking democracy. The spaces for these actions were: meetings HTPC; APM meetings, meetings with parents or guardians; "politics of coffee" etc.. Despite the respondents did not indicate a reference or a theorist of democracy in particular, it was possible to see that realized, procedurally, a democratic relationship within the school and interpersonal relationships.

The present thesis has a result three studies in which the aims were: Study I To propose an assessment method of inspiratory muscle endurance (IME) using the traditional manuvacuometry and the PowerBreathe® device. Moreover, the aim was to verify its viability in patients with Chronic Obstructive Pulmonary Disease (COPD) and healthy. Study II To compare the inspiratory muscle training (IMT) and respiratory exercise (RE) effects associated with physical training (PT) regarding to strength and endurance gain of inspiratory muscles, thoracoabdominal mobility, physical exercise capacity and dyspnea during physical efforts in patients with COPD. In additional, it was to verify if there is a relation of changing gained post training among these variables. Study III To verify if the IMT and/or RE modality associated to PT can provide changes in inspiratory muscle strength, in thoracoabdominal asynchronism and dyspnea at rest and during unsupported upper limb (UL) exercises. Additionally, it was to verify if there is a difference between these both technics modalities. The total sample was composed of 19 healthy subjects and 25 patients with COPD; 13 in the GPT+IMT group and 12 in the GPT+RE. All subjects were assessed before and after training by spirometry; measures of maximum inspiratory (MIP) and expiratory pressures (MEP), IME test, in which was determined the sustained maximum inspiratory pressure (SMIP) and the limit time (Tlim), cirtometry, sixminute walking test (6MWT) and treadmill exercise test (TT). Moreover, reported the modified Medical Research Council (mMRC) and the assessment of respiratory inductance plethysmography (RIP). The IME test was well tolerated. The MIP, MIP %pred, SMIP and SMIP/MIP values were significant lower (p<0.05) in patient with COPD. There was no significant difference between COPD and healthy subjects regarding to Tlim. In the GPT+IMT the MIP, SMIP, abdominal mobility values were significant higher (p<0.05); and, the dyspnea was significantly lower in the 6MWTpeak, TT and mMRC post treatment. However, in both groups there was a significant rise of MIP and SMIP, thoracoabdominal mobility, 6MWD and inclination at TT; and, fall of dyspnea at 6MWTpeak (p<0.05). Only in the GPT+IMT there was a decreased of thoracoabdominal asynchronism at rest and during UL exercises. The PowerBreathe® device associated with the manovacuometry makes acceptable the IME test in patients with COPD and healthy subjects, specially using the incremental load. Both technics increased the exercise capacity and decrease dyspnea at efforts clinically significant. Although, due to the training specificity, only the IMT group was able to improve the inspiratory strength and endurance, which results in a pronounced reduction of dyspnea and thoracoabdominal asynchronism at rest and during UL exercises.
