Padrão alimentar, perfil antropométrico e lipídico em uma amostra de indivíduos com e sem câncer de próstata ou hiperplasia prostática benigna

Santos, Jacqueline Schaurich dos January 2007 (has links)
Patologias prostáticas como a Hiperplasia Prostática Benigna (HPB) e o Câncer de próstata (CaP) apresentam alta incidência, morbidade e mortalidade em indivíduos a partir de 40-50 anos. Fatores ambientais e nutricionais são possíveis fatores envolvidos no desenvolvimento destas doenças. Este trabalho tem por objetivo avaliar o padrão alimentar, perfil antropométrico e perfil lipídico em homens com e sem HPB e CaP e verificar se existe associação entre as variáveis consideradas e a presença de HPB ou CaP na amostra estudada. Foram entrevistados pacientes provenientes do ambulatório de Urologia do Hospital de Clínicas de Porto Alegre (pelo médico da equipe) e preenchida ficha para coleta de dados pessoais e demográficos, história médica e familiar, idade, estágio e grau do tumor, volume da próstata e valor do PSA na época do diagnóstico. Após, os pacientes foram encaminhados à nutricionista para avaliação nutricional (peso, altura, dobras cutâneas, relação cintura/quadril e Recordatório de 24h). O consumo alimentar foi avaliado pelo Recordatório de 24h e analisado pelo programa de apoio à nutrição da Escola Paulista de Medicina – EPM (DIS-EPM, versão 1.5, 2002, UNIFESP). Os pacientes foram orientados a procurar o laboratório de análises clínicas do mesmo hospital para coletar uma amostra sangüínea para dosagem sérica de testosterona total, colesterol total, colesterol HDL e triglicerídeos. O IMC e a circunferência da cintura não apresentaram diferença estatística entre os grupos avaliados. O grupo HPB apresentou consumo menor (p<0,05) de calorias e carboidrato (1875 ± 635 Kcal/dia e 253 ± 105 g/dia) quando comparado ao grupo CaP (2017 ± 476 e 283 ± 75) e ao grupo controle(2179 ± 565 e 302 ± 91). O consumo de fibra alimentar (g/dia) foi significativamente menor (p=0,01) nos grupos HPB (27 ± 12) e CaP (28 ± 10) em relação ao grupo controle (34 ± 15). O consumo aumentado de fibras parece estar relacionado a menor incidência de HPB e CaP. O consumo de calorias e demais nutrientes, o perfil antropométrico e o perfil lipídico não demonstraram relação com estas doenças. / Prostatic pathologies such as Benign Prostatic Hyperplasia (BPH) and Prostate Cancer (PCa) present high incidence, morbidity and mortality among individuals at the age of 40-50 years. Environmental and nutritional factors seem to be involved in the development of these diseases. The objective of the present study is to assess the alimentary pattern, anthropometric and lipid profiles in men with and without BPH and PCa and to verify whether there exists an association among the considered variables and the presence of BPH or PCa in the studied individuals. Urology outpatients from Hospital de Clínicas de Porto Alegre were interviewed by a physician who collected personal and demographic data, medical and familiar history, age, stage and degree of tumor, prostate volume and PSA value at diagnosis. Patients were directed to a nutritionist for nutritional evaluation (weight, height, skin folds, waist/hip ratio and 24-hours recall). Alimentary intake was assessed by 24-hours recall and analyzed by the nutrition support program of Escola Paulista de Medicina – EPM (DIS-EPM, version 1.5, 2002, UNIFESP). Patients were asked to return to the clinical analysis laboratory at the same hospital the following week, in order to collect another blood sample to dose serum total testosterone, total cholesterol, HDL cholesterol and triglycerides. Body Mass Index and waist circumference did not show statistical difference among the assessed groups. The BPH group presented with lower intake (p<0.05) of calories and carbohydrate (1875 ± 635 Kcal/day and 253 ± 105 g/day) when compared tothe PCa group (2017 ± 476 and 283 ± 75) and the control group (2179 ± 565 and 302 ± 91). Fiber intake (g/day) was significantly lower (p=0.01) on BPH (27 ± 12) and PCa groups (28 ± 10) when compared to control group (34 ± 15). Higher intake of fibers seems to be related to lower BPH and PCa incidence. Calories and other nutrients intake, anthropometric profile and lipid profile did not show relation to these diseases.

Professores de piano : um estudo sobre o perfil de formação e atuação em Porto Alegre/RS

Oliveira, Karla Dias de January 2007 (has links)
Esta pesquisa teve como objetivo geral investigar o perfil de formação e atuação dos professores de piano de Porto Alegre/RS. Os objetivos específicos procuraram caracterizar a formação dos professores de piano, caracterizar a atuação dos docentes e identificar as razões e/ou motivações da escolha profissional. Para analisar os dados, este trabalho se apoiou em alguns princípios teóricos baseados na profissionalização do ensino, de acordo com Ramalho, Nuñez e Gauthier (2004). Como método de pesquisa, foi realizado um survey interseccional com professores atuantes no ensino de piano em Porto Alegre e a amostra “bola de neve” foi a estratégia utilizada para se obter as indicações desses professores. Os dados foram obtidos através de um questionário auto-administrado que foi respondido por 104 professores. Os resultados revelaram que os professores que estão atuando com o ensino do piano, em Porto Alegre, parecem aproximar-se dos modelos de professor improvisado, professor artesão e professor como profissional, segundo os modelos baseados em Ramalho, Nuñez e Gauthier (2004). / The purpose of this study is to investigate the profile of piano teachers in Porto Alegre/RS, as to their formation and performance. Other goals include the characterization of these teachers’ formation and their involvement as teachers, identifying the reasons and/or motives of this professional choice. For the analysis of the data, this research is sustained by established theoretical principles in the professionalization of education according to Ramalho, Nuñez and Gauthier (2004). As for the research method, an intersectional survey with active piano teachers in Porto Alegre was conducted; the sample “snow ball” was employed as the strategy to obtain indications from these teachers. The data was gathered through an automanaged questionnaire which was answered by 104 teachers. The results showed that the teachers who are active as piano teachers in Porto Alegre seem to approach the models for the improvised teacher, the teacher craftsman and the professional teacher, according to models based on Ramalho, Nuñez and Gauthier (2004).

No. of bitstreams: 1 dissertao - francisco-1.pdf: 1598375 bytes, checksum: 011e4e3014589fe2de68fb5af51b8aaf (MD5) Previous issue date: 2010 / A crescente demanda de energia em tempos de diminuição no fornecimento de combustível fóssil tem atraído a atenção para a busca por fontes alternativas, que venham a substituir o uso do petróleo, do carvão e do gás natural. Neste contexto, o biodiesel produzido a partir de óleos vegetais aparece como uma alternativa para substituição ao óleo diesel. Esta possibilidade de utilização de combustíveis de origem agrícola vem apresentando um potencial promissor no mundo inteiro, sendo um mercado que cresce aceleradamente devido à sua enorme contribuição ao meio ambiente, com a redução qualitativa e quantitativa dos níveis de poluição ambiental, principalmente nos grandes centros urbanos, e também servindo como fonte estratégica de energia renovável em substituição ao óleo diesel e outros derivados do petróleo. A produção de biodiesel a partir dos óleos vegetais fornece um sistema bifásico, sendo uma fase não polar de ésteres de ácidos graxos e outra mais densa constituída por glicerina e outros componentes residuais do processo. Considerando que na produção de biodiesel há geração de aproximadamente 10% de glicerina, com a mistura constituída de 5% de biodiesel ao diesel (B5) estimativas apontam, em 2013, uma geração de cerca de 150 mil toneladas por ano de glicerina. Uma vez que os mercados tradicionais de glicerina não conseguirão absorver esta oferta de produto neste cenário, este trabalho vem contribuir em inovações tecnológicas relacionadas ao aproveitamento da glicerina, mais especificamente na conversão por via biotecnológica da glicerina gerada na síntese de biodiesel em biomassa de interesse comercial, como fonte de nutrientes. Os efeitos da composição do meio de preparo de inóculo e da temperatura de incubação sobre o crescimento da levedura Yarrowia lipolytica NRRL YB – 423, cultivada em meio à base de glicerina residual, foram estudados em incubadora rotatória, verificando-se que a temperatura de 25°C e utilizando um meio de inóculo com mesma composição do meio de produção foram mais adequados ao crescimento microbiano, atingindo uma concentração de biomassa de 17,7 g.L-1. Em biorreator de bancada, um planejamento fatorial para avaliar a aeração e agitação (22 ensaios mais 3 pontos centrais) foi realizado. Os ensaios indicaram agitação de 200 rpm e aeração de 1 vvm como a melhor condição de cultivo, atingindo 19,14 g.L-1 de concentração de biomassa máxima média, conteúdo protéico médio de 13,55% e teor lipídico de 7,87%. Nestas condições, o cultivo em biorreator de bancada, em relação ao cultivo em frascos agitados, levou a incrementos significativos na biomassa máxima, velocidade específica máxima de crescimento celular e produtividade, respectivamente de 1,22, 1,53 e 2,36 vezes. Com base na determinação do perfil de ácidos graxos e aminoácidos, a biomassa mostrou-se fonte promissora de ácidos graxos essenciais, em particular o ácido linoléico (49,16%) e aminoácidos essenciais como isoleucina, valina, treonina e lisina, que apresentaram escores químicos superiores ao padrão FAO/WHO, respectivamente 1,42, 1,42, 1,30 e 1,17. Portanto a biomassa mostrou-se promissora para utilização como fonte de nutrientes, em particular para alimentação animal. / The crescent demand of energy in times of decreasing in the supply of fossil fuel has been attracting the attention for the search for alternative sources, which will come to substitute the use of the petroleum, coal and natural gas. In this context, the vegetable oils appear as an alternative for substitution to the diesel oil. This possibility of using fuels from agricultural sources has shown a promising potential in the whole world, with a market that is growing rapidly because of its enormous contribution to the environment, with the qualitative and quantitative reduction of the levels of environmental pollution, mainly in the great urban centers, and also serving as strategic source of renewable energy in substitution to the diesel oil and others derived of the petroleum. The production of biodiesel from vegetable oils provides a biphasic system, being a non-polar phase of esters of fatty acids and other more dense consisting of glycerin and other waste components of the process. Considering that in the biodiesel production there is a generation of approximately 10% of glycerin, with the mixture consisting of 5% of biodiesel to diesel (B5) estimates indicate, in 2013, the generation of 150,000 tons per year. Since the traditional markets of glycerin can not absorb this additional supply of product on this scene, this work will contribute in technological innovations related to the use of glycerin, more specifically in the biotechnology conversion of glycerin generated in the synthesis of biodiesel in biomass of commercial interest, as source of nutrients. The effects of temperature and inoculum medium composition on the performance of yeast Yarrowia lipolytica NRRL YB – 423, growing on a glycerin-based medium, were studied in shaken flasks, verifying that the temperature of 25°C and the inoculum medium with the same composition of production medium were the most appropriate conditions for microorganism growth, reaching a biomass concentration of 17.7 g.L-1. In the bioreactor bench scale, a factorial design involving two variables (22 assays plus three central points) was performed, where the studied variables were agitation and aeration. The assays showed agitation of 200 rpm and aeration of 1 vvm as the best culture conditions, reaching a concentration of 19.14 g.L-1 of biomass with protein content of 13.55% and lipid content of 7.88 %. In these conditions, the cultivation in the bioreactor, in relation to the shaken flasks cultivation, leaded to significant increases in the maximum biomass concentration, maximum specific growth rate and productivity, respectively 1.22, 1.53 and 2.36 times. Based on the fatty acid and aminoacid profiles, the biomass showed to be a promising source of essential fatty acids, in particular linoleic acid (49.16%), and essential aminoacids such as isoleucine, valine, threonine and lysine, which presented chemical scores superior than FAO/WHO standard, respectively 1.42, 1.42, 1.30 and 1.17.Therefore biomass showed to be promise for use as a source of nutrients, particularly for animal feed.

Avaliação do perfil do aluno baseado em interações contextualizadas para adaptação de cenários de aprendizagem. / Evaluation of learner profile based on contextual interactions to adaptation of learning scenarios.

Luciana Aparecida Martinez Zaina 18 March 2008 (has links)
A identificação de características que sejam importantes sobre um dado estudante durante o processo de ensino-aprendizagem tem sido alvo de muitos estudos nos últimos tempos. Docentes, coordenadores e pedagogos têm defendido que cada indivíduo possui características particulares e importantes dentro do processo de desenvolvimento do conhecimento. A necessidade de adaptar as estratégias de ensino de acordo com as preferências do aprendiz é uma realidade dentro das salas de aula, sejam estas presenciais ou virtuais. Porém, isto não significa que numa sala de aula deva haver criação de um método para cada aluno, mas sim que se aponte qual a melhor forma de interação para cada um deles construindo grupos de aprendizes com características comuns. Trabalhando desta forma se torna possível identificar perfis de aprendizes dentro de um conjunto de estudantes, possibilitando que se possa trabalhar com conteúdos e ambientes de aprendizagem mais adequados aos aprendizes.O objetivo deste trabalho é apresentar a arquitetura de um sistema que possibilita a criação de cenários de aprendizagem baseados no perfil do aluno. O docente deve indicar as características que devem ser observadas durante as interações do aprendiz em um dado ambiente de aprendizagem eletrônica. Estas características serão modeladas como informações de contexto, permitindo que os pontos definidos como observáveis sejam organizados e modelados de forma a facilitar a monitoração das interações. A classificação do aluno em um determinando tipo de perfil de aprendizagem, previamente definido pelo docente, é realizado considerando-se as informações sobre o contexto da interação e os tipos de perfis de aprendizagem. Para que seja possível construir os cenários de aprendizagem considerando o perfil do aluno este trabalho propõe criar um relacionamento entre os tipos de perfis de aprendizagem e as estratégias de ensino através das categorias descritoras dos objetos de aprendizagem. / The identification of characteristics of a given student that are important during the teachinglearning process has been the focus of numerous studies in recent years. Teachers, coordinators and pedagogues have defended the notion that each individual presents particular and important characteristics in the developing knowledge process. The need to adapt teaching strategies to the student\'s preferences is a reality in classrooms, being physical or virtual classrooms. However, this does not mean that a method should be created for each student in a classroom, but that the best form of interaction for each of them be identified, building groups of learners with common characteristics. Working in this way makes it possible to identify learner profiles within a group of students, allowing one to work with learning contents and environments more suited to the learners. The objective of this work is to present the architecture of a system that allows for the creation of learning scenarios based on the studen profile. The teacher should point out the features which may be observed during the student interaction in a given e-elearning environment. These features are designed as context information, allowing defined observation points to be organized and modeled for facilitating the monitoring of interactions. The student classification in a given learning profile type, defined previously by the teacher, is realized considering information about the context of interaction and the learning profile types. For the learning environment to build the learning scenarios according to the student profile, this work proposes to create a relationship between the learning profile types and the teaching strategies through the description of learning objects categories.

Users from a role perspective : A model to provide a user-centered system development process

Johansson, Ida, Johansson, Stina January 2007 (has links)
Today there exist several systems that lack usability. The reasons are, among others, the pressure to add more features in the system, but also that focus has been earlier on technology and functionality. It becomes more important to think of the user, so that systems can be more usable. By focusing on the user, the user experience can enhance, which results in more satisfied users. User involvement in the system development process is one way to learn and receive information about the user. There are several ways of doing that. One way is to create user portraits from existing user models. We have studied different user models and lack a model that includes both tasks and goals; for example one of the existing models focus on user goals and another on relations with the system. The purpose with this final thesis is to create a model to describe users as roles providing a more effective and generalized user-centered system development process. To create this model, the role profile model, we studied existing theories. By them we were influenced both by good and less good things. The theoretical study resulted in a tentative model that we tested by interview and observe six buyers within the manufacturing industry. This resulted in two role profiles; the strategic buyer and purchase planner. From the result of the interviews and observations, we improved the tentative role profile model to our final model. There were some factors that did not fit in the tentative model and some that we added. The role profile model contains three elements; objectives, requirements and context. These elements consist of a number of attributes that are important when surveying a role profile. The uniqueness with the role profile model is the fact that it includes both role specific attributes and attributes that puts the role profile into a context. The model contains for example work process, system requirements, responsibility and authority. The role profile is at part of a greater context. There are design philosophies that concern the whole system development process; from survey the user to design and test. Our role profile model only handles the first parts, the user and tasks, due to the time limitations. We have created a practical procedure that we recommend to facilitate the usage of the role profile model. The practical procedure is based on our choices of method when testing the tentative role profile model. The central in our practical procedure are interviews and observations. It is important to plan the company visits so that all necessary information is received. The usage of the role profile can for example contribute with: knowledge and understanding of the users, structured work procedure, a generally accepted terminology and a user-centered design process. This final thesis has been performed on commission of Lawson Software. We had continuously discussions with them about usability and the role profile model. We have studied fields of applications for the role profile model at Lawson. We think they can use the model in the product requirement process, design and evaluation, work with composite applications, user understanding and user priority and introduction of new employees. / Idag finns det ett flertal system som har bristande användar¬vänlighet. Detta beror bland annat på påtryckningar att lägga till fler funktioner i systemen, men också på att det bakåt i tiden har fokuserats på att utveckla system utifrån teknologi och funktionalitet. Det blir allt viktigare att tänka på användaren så att systemen blir mer användarvänliga. Genom att fokusera på användaren kan man öka användarupplevelsen i systemet och det medför att användarna blir nöjdare. Att involvera användaren i utvecklingsprocessen är ett sätt att lära känna och få information om användaren. Det finns många sätt att göra det på. Ett sätt är att skapa användarporträtt med hjälp av olika befintliga användarmodeller. Vi har studerat olika användarmodeller och sett att det saknas en användarmodell som inkluderar både fokus på användarens arbetsprocess och dess mål; till exempel en av de existerande modellerna fokuserar på användarens mål och en annan på relationer med system. Syftet med detta examensarbete är därför att skapa en modell som beskriver användare som roller, som bidrar till en effektivare och bredare användar¬centrerad systemutvecklingsprocess. För att ta fram denna modell, rollprofilsmodellen, studerade vi som sagt existerande teorier. Från dem påverkades vi både av delar som vi tyckte var bra och mindre bra. Vi kom fram till en hypotesmodell som vi testade genom att intervjua och observera sex inköpare på tillverkande företag. Detta resulterade i två rollprofiler; den strategiska inköparen och inköpsplaneraren. Utifrån resultaten av intervjuerna och observationerna förbättrade vi hypotesen till vår slutliga modell. Det fanns vissa faktorer som vi inte tyckte passade in, men även attribut som borde läggas till. Rollprofilsmodellen innehåller tre delar; mål, krav och kontext. Dessa delar består av ett antal attribut som är viktiga att undersöka hos den rollprofil som ska skapas. Det som utmärker rollprofilsmodellen är att den inkluderar både roll¬speci¬fika mål och attribut som sätter rollprofilen i en kontext. Modellen innehåller till exempel relationer, krav, ansvar och befogenheter. Rollprofilen är en del av en större kontext. Det finns designfilosofier som berör hela systemutvecklingsprocessen; från att kartlägga användaren till att designa och testa. På grund av tidsbegränsningar har vi enbart berört de första av dessa delar; användaren och arbetsuppgifter. För att underlätta användandet av rollprofilen har vi skapat ett rekommenderat praktiskt tillvägagångssätt. Detta är baserat på våra egna metodval när vi testade vår hypotesmodell. Det centrala i det praktiska tillvägagångssättet är intervjuer och observa¬tioner. Det är viktigt att planera noggrant så att all nödvändig informa¬tion erhålls. Användandet av rollprofilen kan till exempel bidra till: kunskap och förståelse av användaren, ett strukturerat arbetssätt, en allmänt accepterad terminologi samt en användar¬centrerad utvecklingsprocess. Detta examensarbete har utförts på uppdrag av Lawson Software, med vilka vi kontinuer¬ligt har fört diskussioner om användbarhet och rollprofilsmodellen med mera. Vi har även utforskat vilka potentiella användningsområden som rollprofilen har på Lawson. Lawson skulle kunna använda modellen i kravhanteringsprocessen, design och utvärdering, arbete med komposita applikationer, användarförståelse och priori¬teringar samt intro¬ducerande av nyanställda.

Bioinformatický nástroj pro odhad abundance bakteriálních funkčních molekul v biologických vzorcích na základě metagenomických dat 16S rRNA / Bioinformatic Tool for Estimation of Abundances of Bacterial Functional Molecules in Biological Samples Based on 16S rRNA Metagenomic Data

Bieliková, Michaela January 2019 (has links)
Ľudské telo je prostredím pre život neuveriteľného množstva mikróbov. Niektoré z nich môžu spôsobovať rôzne choroby, ale ďalšie, napríklad črevný mikrobióm, sú pre život a zdravie človeka nepostrádateľné. Nanešťastie, črevný mikrobióm nie je detailne preštudovaný, pretože obsahuje tisíce rôznych druhov baktérií, z ktorých väčšina sa nedá kultivovať v laboratórnych podmienkach. Riešením tohto problému sú nové rýchle metódy sekvenovania v kombináciou s bioinformatickými nástrojmi na výpočet funkčného profilu baktérií vo vzorke. V tejto práci si predstavíme existujúce nástroje predpovedajúce funkčný profil, a následne navrhneme nový nástroj, ktorý môže implementovať konsenzus nad výsledkami existujúcich nástrojov, alebo sa môže jednať o úplne nový nástroj.

The Contribution of Couple Leisure Involvement, Leisure Time and Leisure Satisfaction to Marital Satisfaction

Johnson, Heather Ann 28 July 2005 (has links) (PDF)
The purpose of this study was to further clarify the relationship between couple leisure patterns and marital satisfaction by examining the contribution of joint couple leisure involvement, leisure time, and leisure satisfaction to couples' satisfaction with married life. The sample consisted of 48 married couples (N = 96). The Marital Activity Profile (MAP), a modified version of the Family Leisure Activity Profile (FLAP) was used to determine couple leisure involvement in core and balance leisure activities and leisure satisfaction. The Satisfaction With Married Life (SWML), a modified version of the Satisfaction With Life Scale (SWLS) was used to measure marital satisfaction. Blocked multiple regression analyses indicated a positive relationship between satisfaction with couple leisure and marital satisfaction, specifically satisfaction with core leisure activity patterns. Implications and recommendations for further research are discussed.

Wheel Wear Simulation of the Light Rail Vehicle A32

Robla Sánchez, Ignacio January 2010 (has links)
During the last decade, a novel methodology for wheel wear simulation has been developed in Sweden. The practical objective of this simulation procedure is to provide an integratedengineering tool to support rail vehicle design with respect to wheel wear performance and detailed understanding of wheel-rail interaction. The tool is integrated in a vehicle dynamicssimulation environment.The wear calculation is based on a set of dynamic simulations, representing the vehicle, the network, and the operating conditions. The wheel profile evolution is simulated in an iterativeprocess by adding the contribution from each simulation case and updating the profile geometry.The method is being validated against measurements by selected pilot applications. To strengthen the confidence in simulation results the scope of application should be as wide aspossible in terms of vehicle classes. The purpose of this thesis work has been to try to extend the scope of validation of this method into the light rail area, simulating the light rail vehicleA32 operating in Stockholm commuter service on the line Tvärbanan.An exhaustive study of the wear theory and previous work on wear prediction has been necessary to understand the wear prediction method proposed by KTH. The dynamicbehaviour of rail vehicles has also been deeply studied in order to understand the factors affecting wear in the wheel-rail contact.The vehicle model has been validated against previous studies of this vehicle. Furthermore new elements have been included in the model in order to better simulate the real conditionsof the vehicle.Numerous tests have been carried out in order to calibrate the wear tool and find the settings which better match the real conditions of the vehicle.Wheel and rail wear as well as profile evolution measurements were available before this work and they are compared with those results obtained from the simulations carried out.The simulated wear at the tread and flange parts of the wheel match quite well the measurements. However, the results are not so good for the middle part, since themeasurements show quite evenly distributed wear along the profile while the results from simulations show higher difference between extremes and middle part. More tests would benecessary to obtain an optimal solution.
