Abstract The project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers. The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group. The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy. The project began with an extensive research, including a visit to one of the world's largest toy fair in Nürnberg, Germany, and a comprehensive survey of parents' attitude to sound toys. Based on the first sketching phase three concepts where chosen; Module Cars, Beat Box and Record Player. Module Cars was a concept where you could replace parts of the car and in that way get different sounds. Beat Box was a box of three cylindrical blocks which consisted of various surfaces and materials. While they were spinning in the box they would hit different materials and in that way create different sound and rhythms. The construction of the idea meant that over a thousand different sounds and rhythms could be created. Record Player was a similar concept in which the child could change the discs and in that way create different rhythms and sounds. Together with the product development department, I decided to keep working with the Modul Car concept. Within this concept, I chose to work on two different tracks, different fronts and figures. By changing the front of the car it would get a new sound or by changing the driver in the car it would also get a new sound. After several weeks of shaping digital 3D models and many ideas and thoughts later I finally reached a solution that was built as a prototype. The result is a vehicle where the front can be replaced by two other fronts. Depending on which, the system will give you different sounds. This is because each front has a plastic flap placed underneath that hits a piece of plastic stuck to the wheel axle. Nine children play tested the toy and their parents were responding to questions about the outcome. The play tests went well and it turned out to be a suitable toy from one year and up to about five years. The play takes various forms in different ages which is good since this means that the toy may last longer. The response among the parents was also very positive. I am very pleased with the outcome and hope to see it in store shelves one day and also that it becomes played with in homes. / Sammanfattning Projektet "Sound and Play" har genomförts i samarbete med leksaksföretaget BRIO i Malmö. Syftet med projektet var att undersöka hur BRIO i framtiden skulle kunna utveckla leksaker kring ljud i ålderskategorin 12-36 månader. De problemformuleringar som skulle besvaras efter slutfört projekt var "På vilket sätt skulle BRIO kunna bredda sitt sortiment med hjälp av ljudleksaker?", "Hur kan man kombinera leksaker och ljud på ett intressant sätt för barn?", "Hur skapar man en leksak med ljud som är rolig för barnet, men samtidigt inte är irriterande för föräldrar?". BRIO har i dagsläget endast två leksaker med ljud i denna ålderskategori. Leksakens uttryck skulle vara en mix av klassiskt och coolt och den övergripande känslan skulle vara upptäckande samt väcka nyfikenhet. Känslan skulle förmedlas genom enkelhet och glädje. Projektet inleddes med en omfattande research med bland annat ett besök på en av världens största leksaksmässor i Nürnberg, Tyskland samt en omfattande enkätundersökning av föräldrars attityd till ljudleksaker. Utifrån en första idégenereringsfas valdes tre koncept ut; Modul Cars, Beat Box och Record Player. Modul Cars byggde på att man skulle kunna byta ut en del på bilen och på så sätt få olika ljud, t.ex. att man skulle kunna byta hjul eller underrede. Beat Box var en låda med tre cylinderformade klossar i. Dessa bestod av olika ytor och material som i lådan slog emot tre olika material. Konstruktionen av idé innebar att över tusen olika ljud och rytmer skulle kunna skapas. Record Player var ett liknande koncept där barnet skulle kunna byta "skivor" och på så sätt skapa olika rytmer och ljud. Tillsammans med produktutvecklingsavdelningen bestämde jag mig för att arbete vidare med modul cars. Inom detta koncept valde jag att arbeta vidare med två olika spår; olika fronter och gubbar. Antingen skulle man genom att byta fronten på bilen få olika ljud eller att man istället hade en bil med gubbar och där den som var föraren bestämde ljudet. Efter flera veckors caddande och många idéer och tankar senare så hade jag till slut tagit fram ett koncept med tre fordon som jag skulle bygga modell på. Resultatet är ett fordon som är bussliknande och där fronten går att byta ut. Beroende på vilken front man använder så låter leksaken olika. Detta beror på att varje front har en plastflärp undertill som träffar var sin plastbit som sitter fast på hjulaxeln. Modellen lektestades på nio barn och deras föräldrar fick även vara med och svara på frågor kring resultatet. Lektesterna gick bra och det visar sig vara en passande leksak från ett år och upp till cirka fem år. Leken tar sig olika uttryck i de olika åldrarna vilket är positivt då detta gör att leksaken får en längre livslängd. Mottagandet av leksaken bland föräldrarna var också mycket positivt. Jag är mycket nöjd över resultatet och hoppas att den någon dag i framtiden står i butikshyllor runt om i Sverige och även att den blir nött och vällekt med i hemmen.

The study of visual ability is of great importance, especially in the manifestations of senile cataracts, and their implications on body imbalances that can compromise the static and dynamic control of the elderly. Objectives: To evaluate the influence of visual conditions in patients with senile cataract with increasing imbalances in the body, and compare them with gender, age, education, physical activity, falls and fear of falling. Methodology: A descriptive and analytical study using a quantitative longitudinal cohort study was conducted. The statistical analysis program used was the chi-square or Fisher's exact test, the Student test and the Mann-Whitney test. Values of p <0.05 were considered. The study included 30 individuals, 15 men and 15 women, were evaluated before surgery for senile cataract, 30 and 60 days after surgery. Were used for data collection, the Mini Mental State Examination (MMSE), the Berg Balance Scale (BBS), the Short Physical Performance Battery (SPPB), International Falls Efficacy Scale adapted to Brazil (FES-I-BRAZIL) and medical history questionnaire. Results and Discussion: Of the 15 elderly women, by SPPB, after 60 days postoperatively, it was noted that 13 women (87%) have achieved a moderate performance and 2 (13%) remained poor performance of lower limbs. Assessing the FES-I-BRAZIL test, it was observed that after 60 days post-surgery, 3 (20%) elderly remained mild concern with falls. Of the 15 elderly men subjects evaluated by BBS test, before and after 30 and 60 days after surgery, it was observed that 1 (7%), manages to maintain some balance but needed assistance; and 14 (93%) seniors have maintained a good balance or are independent for Daily Life Activity (DLA). Evaluating the SPPB test, it was observed that 60 days after surgery, the elderly 5 (33%) had moderate performance and 9 (67%), good results SPPB. Conclusion: The senile cataract surgery can offer positive prevented effects on the performace of inferior members, balance and fear of falling in elderly functioning as an important tool for preventing unbalance and reducing the risk of falls, common in the physiological process of aging. / A preval??ncia de desequil??brios e de quedas em idosos tem persistido nas ??ltimas d??cadas devido a fatores do envelhecimento populacional.

The aged of Centro de Conviv??ncia do Idoso were selected for carrying out measurement of thoracic kyphosis angle from Flexicurve method. The postures of 153 elderly women were evaluated, using at least 25 with kyphosis and 25 with normal standard curve for the study follow-up. Following, physical therapy evaluation was performed to identify the elderly ineligible for the study, then the balance tests were conducted static and with functional reach test (FRT) associate with baropodometry platform. Also, elasticity tests were performed with Well???s bank. The Mann-Whitney test was used to establish the comparison of variables: age; anthropometric data; FRT; Well???s bank; and data obtained by the F-Scan. Also Pearson correlation was performed to correlate the degree of thoracic kyphosis with the results of FRT; and to establish the correlation between the thoracic kyphosis and the data obtained with the F-Scan. And also for correlate the result of the FRT with Fscan data. Statistically significant differences between the variables in comparison tests were not observed; for correlation tests, we found significant correlation only between FRT and the pressure center shifts in the anteroposterior direction of the dynamic tests. The study concluded that the achievement of TAF was not influenced by increased thoracic kyphosis angle. / O objetivo do trabalho foi avaliar a influ??ncia do ??ngulo da cifose dorsal no deslocamento do centro de press??o em idosas durante a realiza????o de uma atividade funcional.

Utifrån temat Hållbart Samhälle och aspekten Socialt Hållbart Samhälle, är denna uppsats en berättelse om ett examensarbete som tagit sig an leken i förhållande till funktionsnedsättningen autism hos barn och där frukten av examensarbetet blivit en leksaksprodukt. Med hjärta, hjärna och engagemang har jag undersökt utifrån mina användare hur jag kan skapa en artefakt med potential att ge mina användare förutsättningar som de behöver för att leka, samspela och kommunicera. Men även andra barns behov i lek, samspel och kommunikation har varit viktiga att tillgodose då målet har varit att möjliggöra det sociala samspelet mellan båda dessa parter. Med andra barn menas barn oavsett funktionsnedsättning eller ej. Målet har därmed även varit att formge en leksaksprodukt som möter dessa två parters behov, såväl till form som funktion. Visuellt ska leksaksprodukten inte ge något uttryck av hjälpmedel, utan ska snarare vara en leksak som dolt kan tillgodose behoven hos barn med autism. Examensarbetet har även varit en möjlighet för mig som designstudent att få lära mig om hur företag arbetar med design för barn, vilket har lett mig till företaget BRIO AB som givit sina erfarenheter samt åsikter till leksaksprodukten. Leksaksprodukten har även på så sätt haft utgångspunkten i vad jag som designer tror skulle kunna passa in i BRIOs sortiment av leksaker. Som designer har jag ambitionen att arbeta med lekfull och hållbar design för barn. Barn med autism var ett steg för mig att ge mitt område större komplexitet för att ge mig en möjlighet att utvecklas. / Kiwi Bird Box - Leksaker för alla

Pesquisa do estado de Minas Gerais (FAPEMIG) / Com este trabalho, objetivou-se estudar os efeitos do balan?o eletrol?tico (BE) em ra??es para su?nos na fase de crescimento. O experimento foi conduzido no Setor de Suinocultura da Escola Estadual Jer?nimo Pontello em Couto de Magalh?es de Minas, MG, durante os meses de fevereiro e mar?o de 2011. Foram utilizados 36 leit?es h?bridos comerciais, 18 machos castrados e 18 f?meas, em fase de crescimento, com peso inicial 23,48 ? 1,68 kg, distribu?dos em delineamento experimental inteiramente casualisados, com cinco tratamentos e tr?s repeti??es, sendo a unidade experimental composta por dois animais (um macho e uma f?mea), na baia. Os animais permaneceram em experimento recebendo ra??o e ?gua ? vontade at? atingirem o peso de 55,98 ? 4,05 kg. As condi??es ambientais do galp?o foram monitoradas diariamente, utilizando termo-higr?metro, a leitura dos equipamentos foi utilizada para caracterizar o ambiente t?rmico da instala??o. Os animais receberam cinco ra??es, sendo: 100, 150, 200, 250 e 300 mEq/kg. Para corre??o do BE, foram utilizadas inclus?es de bicarbonato de s?dio e, ou, cloreto de c?lcio em substitui??o ? areia lavada. Durante o per?odo experimental, as vari?veis avaliadas foram consumo de ra??o di?rio (CRD), ganho de peso di?rio (GPD), convers?o alimentar (CA), temperatura retal (TR) e superficial (TS), frequ?ncia respirat?ria (FR) e n?vel dos eletr?litos no sangue. A temperatura observada foi 25,89 ? 1,53 ?C com UR do ar de 78,5 ? 11,15 %, temperatura de globo negro de 26,1 ? 2,64 ?C e ITGU calculado em 75,0 ? 2,69, condi??es estas consideradas como moderado desconforto t?rmico para su?nos em crescimento. O BE n?o influenciou o desempenho (CRD, GPD, CA) de su?nos em crescimento, no entanto, promoveu altera??es na consist?ncia f?sica das fezes para as caracterizadas como pastosas e diarreicas. N?o houve efeito do BE na frequ?ncia respirat?ria, assim como para as demais caracter?sticas fisiol?gicas. N?o houve diferen?a estat?stica para os n?veis de eletr?litos no sangue dos animais. A corre??o do BE da ra??o n?o se faz necess?ria, visto que o desempenho n?o ? alterado dentro da faixa de 100 a 300 mEq/kg, faixa na qual se encontra o BE de ra??es pr?ticas e daquelas com teores reduzidos de prote?na bruta. / Disserta??o (Mestrado) ?

The experiment was conducted in Couto Magalh?es de Minas, MG, during the months of February and March 2011. Were used 36 commercial hybrid swine, 18 males castrated and 18 females in the growth phase, with initial body weight 23.48 ? 1.68 kg, distributed in a completely randomized experimental design with five treatments and three replications, and the experimental unit composed of two animals (one male and one female), in the box. The animals were fed diets in an experiment and water ad libitum until they reach the average weight of 55.98 ? 4.05 kg. The environmental conditions were evaluated, characterizing the thermal environment of the installation. The animals received five rations, as follows: 100, 150, 200, 250 and 300 mEq/kg. For correction of EB, inclusions were used sodium bicarbonate and either calcium chloride to replace the washed sand. During the experimental period, the variables analyzed were daily feed intake (DFI), daily gain (DG), feed conversion (FC), superficial and rectal temperature, respiratory frequency and level of electrolytes in the blood. The average temperature was 25.89 ? 1.53 ?C with relative humidity of the air 78.5 ? 11.15 %, black globe temperature of 26.1 ? 2.64 ?C and BGT estimated at 75.0 ? 2.69, conditions considered as moderated thermal discomfort. The EB didn?t influence on performance parameters (DFI, DG, FC) for growing swine, however, led to changes in the stools of growing swine to diarrhea and loose stools. The EB didn?t influence on respiratory frequency and others physiological parameters. There wasn?t statistical difference for levels of electrolytes in the blood of animals. The correction of EB ration isn?t necessary, the performance isn?t changed in the range 100 to 300 mEq/kg, range of the feed practical and with low levels of crude protein.

Para isso, o estudo foi dividido em duas etapas. Na primeira etapa 17 indiv?duos sedent?rios foram submetidos a uma sess?o de exerc?cio intervalado de alta intensidade (HIIE, do ingl?s high intensity interval exercise), no cicloerg?metro, composta por 8 est?mulos, a 90% da pot?ncia m?xima, intercalados por 75 segundos de recupera??o ativa a 30 watts. Antes e, imediatamente, ap?s o exerc?cio amostras de sangue foram coletadas para a avalia??o da concentra??o de subst?ncias reativas ao ?cido tiobarbit?rico (TBARS) e da capacidade antioxidante total do plasma; e a concentra??o de TBARS e atividade das enzimas antioxidantes super?xido dismutase (SOD) e catalase (CAT), no lisado eritrocit?rio. Agudamente, o HIIE n?o alterou a concentra??o plasm?tica de TBARS, embora a capacidade antioxidante total do plasma tenha sido significativamente menor (p=0,05) imediatamente ap?s o exerc?cio. N?s eritr?citos, a concentra??o de TBARS foi significativamente menor (p=0,03), enquanto a atividade da SOD foi significativamente maior (p=0,04), imediatamente ap?s o exerc?cio. Na segunda etapa 9 indiv?duos, que participaram do HIIE, foram submetidos a um programa de treinamento intervalado de alta intensidade (HIIT, do ingl?s high intensity interval training), 3 vezes por semana, durante 4 semanas (12 sess?es de treinamento). Par?metros do estado redox foram avaliados antes e ao final do treinamento. O HIIT aumentou (p=0,05) a capacidade antioxidante total do plasma, e, nos eritr?citos, a concentra??o de TBARS foi menor (p=0,03) e a atividade da catalase foi maior (p=0,04) ap?s o treinamento. As modifica??es do estado redox sangu?neo alcan?adas em curto prazo com o programa de HIIT utilizado neste estudo podem ser consideradas uma resposta ben?fica adicional para a esta modalidade de treinamento, e neste contexto o HIIT pode ter um papel terap?utico nas condi??es cl?nicas decorrentes ou associados a um quadro de desequil?brio redox. / Disserta??o (Mestrado) ?

First, 17 sedentary subjects underwent a session of high intensity interval exercise (HIIE), on a cycle ergometer, consisting of 8 stimuli, at 90% of maximum power, with intervals of active recovery of 75 seconds, at 30 watts. Before and immediately after exercise, blood samples were collected to evalute plasma thiobarbituric acid reactive substances (TBARS) concentration and plasma total antioxidant capacity; and TBARS concentration and activity of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT), at erythrocyte lysate. Acutely, HIIE did not alter plasma TBARS concentration, although plasma total antioxidant capacity was significantly lower (p=0,05) immediately after exercise. In erythrocytes, TBARS concentration was significantly lower (p=0,03), while SOD activity was significantly higher (p=0,04) immediately after exercise. In the second moment, 9 individuals, who participated in HIIE, underwent a high-intensity interval training (HIIT) program, 3 times a week, during 4 weeks (12 training sessions). Redox state parameters were evaluated before and at the end of training. HIIT increased (p=0,05) plasma total antioxidant capacity and, in erythrocytes, TBARS concentration was lower (p=0,03) and catalase activity was higher (p=0,04) after training. Changes on blood redox state promoted by HIIT can be considered an additional beneficial response to this type of training, and HIIT may have a therapeutic role in clinical conditions associated with redox imbalance.

O CO2, por exemplo, estar presente em mais de 25% do ?leo extra?do da camada do pr?-sal entre as bacias de Campos e Santos. Estimativas apontam que somente nas duas ?reas com reservas delimitadas - os campos de Tupi e Iara, onde h? um ac?mulo de at? 12 bilh?es de barris de ?leo e g?s - existam 3,1 bilh?es de toneladas de CO2, um dos gases que contribuem para o aquecimento do planeta. Devido a essa grande quantidade de contaminantes (CO2, N, S, etc.) presente na mistura de hidrocarbonetos extra?da dessas bacias, ? preciso buscar novas pr?ticas de separa??o deste contaminante. Para tal desenvolvimento de novas pr?ticas ? importante um estudo constante sobre o equil?brio termodin?mico entre os constituintes do petr?leo e seus contaminantes. Com isso o objetivo ? construir um equipamento que gere condi??es suficientes para poder verificar o comportamento de fase de v?rios sistemas de interesse da ind?stria do petr?leo com seus contaminantes mais comuns, por exemplo: CO2 a alta press?o utilizando o conhecimento pr?vio do grupo Neto, 2010 de pesquisa, que deve operar em press?es e temperaturas de at? 300 bar e temperatura at? 100 graus Celsius. Alguns sistemas de interesse s?o: CO2 e alcanoaminas (monoetanolamina, dietanolamina, trietanolamina). ?gua e ?lcool laur?lico etoxilado e CO2 e alcanos com leve contamina??o de ?gua. / Oil is a complex mixture having predominantly paraffinic hydrocarbons, naphthenic and aromatic (Freitas and Costa, 1969) and other constituents (sulfur, nitrogen and oxygen) that normally occur in the form of organic compounds. The CO2, for example, be present in over 25% of the oil extracted from the pre-salt layer of the Campos and Santos basins. Estimates suggest that only in two areas with defined reserves - the Tupi and Iara, where there is an accumulation of up to 12 billion barrels of oil and gas - there are 3.1 billion tons of CO2, one of the gases that contribute to warming. Because of this large amount of contaminants (CO2, N, S, etc.) present in the mixture of hydrocarbons extracted these basins, it must find new ways of separation of this contaminant. For such development of new practices is important a constant study of the thermodynamic equilibrium between oil constituents and their contaminants. Thus the goal is to build a device that generates enough conditions to check phase behavior of various oil industry's interest systems with their most common contaminants, eg CO2 at high pressure using prior knowledge of Guerra-Neto, 2010, which must operate at temperatures and pressures up to 300 bar and temperatures up to 100 degrees Celsius. Some systems of interest are: CO2 and alcanoaminas (monoetanolamine, dietanolamine, trietanolamine). Lauryl alcohol ethoxylate and water and CO2 and alkanes with mild contamination of water.

A pr?tica de atividade f?sica ? considerada uma interven??o tanto terap?utica, quanto preventiva, que ? capaz de evitar muitas altera??es relacionadas ao processo de envelhecimento. Assim, o objetivo do estudo foi investigar a associa??o entre a pr?tica de atividade f?sica, equil?brio, funcionalidade e quedas em idosas institucionalizadas e n?o institucionalizadas. M?todos: estudo transversal e observacional, onde foram avaliadas idosas da Comunidade (praticantes de atividade f?sica regular) e idosas residentes em uma institui??o de longa perman?ncia para idosos (ILPI) quanto ? idade, escolaridade, hist?rico de quedas, fraturas, n?vel de atividade f?sica (International Physical Activity Questionnaire - IPAQ), desempenho nos testes funcionais timed up and go (TUG), de agilidade e equil?brio din?mico (AGIL), Senta/Levanta e na Escala de Equil?brio de Berg (BBS). Resultados: foram avaliadas 81 idosas, sendo 50 (61,7%) da ILPI e 31 (38,3%) da Comunidade. A m?dia da idade foi de 75,5?10,4 anos. Nas idosas da ILPI, foram observados resultados significativos em rela??o ? idade, baixa escolaridade e a menor ?ndice de atividade f?sica (p<0,001). N?o se observou diferen?a estatisticamente significativa em rela??o ?s quedas nem ?s fraturas. As idosas da Comunidade tiveram melhor desempenho em todos os testes funcionais (p<0,001). Observou-se que todos os testes de equil?brio e funcionalidade apresentaram uma correla??o significativa e de grau forte na amostra geral. Estas correla??es mantiveram-se significativas, por?m em magnitude menos expressiva entre as idosas da ILPI. J? nas idosas da Comunidade, observaram-se apenas duas correla??es significativas e moderadas (AGIL x Senta/Levanta e Berg x TUG). O teste TUG foi o ?nico que se mostrou significativo para predizer a ocorr?ncia de quedas (idosas com TUG?11 segundos tinham aproximadamente 4 vezes mais chance de apresentar quedas). Conclus?o: o n?vel de atividade f?sica e o desempenho nos testes de equil?brio est?tico e din?mico de for?a de membros inferiores foram significativamente inferiores nas idosas da ILPI. O teste que mais se mostrou eficiente para a predi??o de queda foi o TUG
