Dentro desta abordagem buscou-se especificamente descrever as características pessoais e antropométricas dos participantes, seu nível de atividade física e de CM e a existência de relação entre estes aspectos. Na revisão de literatura realizada para a construção do marco teórico não foi encontrada informação suficiente sobre o desenvolvimento da CM em pessoas com SD na infância, dentro da faixa etária aqui estudada. Embora tenha-se encontrado vários pesquisadores do Brasil que publicaram sobre o desenvolvimento da CM em pessoas com deficiência intelectual e com SD, e utilizaram uma fermenta de reconhecido prestigio como o teste Kórperkoordinationstest für Kinder. Respeito ao método, desenvolveu-se um estudo de natureza quantitativa, de tipo descritivo com uma abordagem transversal. Foram utilizados um questionário exploratório, previamente validado; o Questionário de Atividade Física Infantil, Physical Activity Questionnaire for o/der Children (PAQ-C), para avaliar o nível de atividade física; o Teste de Coordenação Corporal para crianças, Korperkoordinationstest für Kinder (Teste KTK), para avaliar a CM; e, técnicas padronizadas de medição antropométricas para medir o peso a altura, que proporcionaram o Índice de Massa Corporal (IMC) e as dobras cutâneas tricipital e subescapular, que proporcionaram o índice de porcentagem de gordura. Participaram do estudo 17 crianças com SD de ambos gêneros, com idade entre sete e 10 anos, vinculados à fundações e centros escolares da província de Barcelona. Para o tratamento dos dados, utilizou-se os programas Microsoft Office Excel versão 2010 e IBM SPSS Statistics versão 23.0, bem como as técnicas paramétricas após a comprovação da normalidade dos dados. E foram realizadas estatísticas descritivas (media e desvio padrão), estatística comparativa através do teste "t" de Student para a comparação entre dois grupos e ANOVA de um fator (post hoc - Bonferroni) para mais de dois grupos e estatística correlativa para correlacionar as variáveis quantitativas através do teste de correlação de Pearson. O nível de significação assumido foi de 5% (p,0,05). Como resultados mais relevantes se conseguiu observar que as características pessoais dos participantes, em quanto a tipologia e doenças, são as mesmas apresentadas frequentemente. Observou-se que todos os participantes estavam estudando e que 24% sabem ler e escrever. Os participantes realizam atividades sedentárias (assistir televisão ou jogar videogame/computador/tablet) em quantidades aceitáveis, de maneira idêntica a população sem deficiência. Observou-se que 18% não participou de programas de estimulação precoce, fato que não apresentou relevância nas variáveis antropométricas nem nas variáveis coordenativas. Os participantes apresentaram altura, peso e IMC dentro da normalidade segundo os valores de referencia das tabelas de crescimento para população com SD. Com relação às tabelas de crescimento para pessoas sem deficiência se pode perceber que o peso estava dentro da normalidade e a altura se encontrava abaixo da esperada para a idade. Fato que contribuiu para que o IMC também apresentasse resultado alterado, com indicações de sobrepeso e obesidade. De todas as variáveis antropométricas pesquisadas, somente houve diferença significativa entre gênero na variável dobra cutânea subescapular, com resultado superior para as meninas. As meninas apresentaram uma tendência a alcançar uma maior porcentagem de gordura que os meninos. Os participantes deste estudo não seguem as recomendações da Organização Mundial da Saúde sobre a quantidade de atividade física. Esta constatação corrobora o resultado dos níveis de atividade física encontrados através do PAQ-C, entre moderadamente ativo, sedentário e muito sedentário. Os níveis de CM foram classificados abaixo da normalidades, mais específicamente com insuficiência coordenativa e perturbação na coordenação. Estes dados não demonstraram relevância quando foram comparados entre si, entretanto, houve correlação positiva, de intensidade fraca, entre a pontuação final do Teste KTK e do PAQ-C. Em quanto ao Teste KTK, em geral, os meninos apresentaram maior pontuação que as meninas em todas as tarefas, entretanto, não houve diferença significativa entre gêneros. Observou-se diferença significativa entre o nível de atividade física e as variáveis antropométricas somente no IMC. Esta diferença foi constatada entre os sedentários e os moderadamente ativos. não houve correlação entre as variáveis antropométricas e o resultado PAQ-C / Abstract: This doctoral thesis focused on the studies on motor coordination (MC) and its relationship with anthropometry and physical activity level in people with Down Syndrome (DS), mainly aged between seven and 10 years, a subject on which very little research has been done. Within this approach, it was specifically proposed to describe the personal and anthropometric characteristics of the participants, their level of physical activity and MC level and the existence or absence of a relationship between all these aspects. From the literature review conducted for the construction of the theoretical framework, no extensive information about the development of MC of DS in childhood within the age range studied here were found. Nevertheless have found several researchers from Brazil who have published on the development of MC in people with intellectual disabilities and DS, and have used a recognized prestige tool, the Test Korperkoordinationstest für Kinder. Regarding the method, a quantitative study of descriptive type with a transversal approach was developed. To carry out this research an exploratory questionnaire, previously validated, was used. Additionally, a Physical Activity Questionnaire for Children (PAQ-C) to assess the level of physical activity; a Body Coordination Test for Children - Korperkoordinationstest für Kinder (KTK Test) - to evaluate the MC, and standardized anthropometric measurement techniques to measure weight and height which provided the Body Mass Index (BMI) and the triceps and subscapular skinfolds, indicating the fat percentage index, were also applied. 17 people with DS of both sexes, aged between seven and 10 years, linked to foundations and schools in the province of Barcelona, participated in the study. For the data analysis, the programs Microsoft Office Excel version 2010 and IBM SPSS Statistics version 23.0 were used. After checking the normality of the data, parametric techniques were used. Descriptive statistics (mean and standard deviation), comparative statistics through Student's test for comparison between two groups and one-way ANOVA (post hoc - Bonferrori) for more than two groups and correlative statistics through the Pearson test were used. The level of significance was 5% (p <0.05). Among the most relevant results of the study, it was observed that the personal characteristics of the participants are the same ones presented frequently in terms of typology and illness. All the participants were studying and 24% were able to read and write. Participants engage in sedentary activities (watching TV or playing console/computer/tablet) in acceptable amounts, in a identically manner to the non-disabled population. It was observed that 18% did not participate in early care programs, a fact that did not show relevance in the anthropometric variables or in the coordinating variables. The participants presented height, weight and BMI within the normal range according to the reference values in the specific growth chart for population with DS. The analysis of the same variables from the growth charts for people without disabilities determined that the weight was within normal; however, the height was below the expected one for the age. It contributed to the BMI also being altered, with indications of overweight and obesity. In all the anthropometric variables investigated, there was only significant difference between genders in the variable subscapular skinfold, with girls reaching a higher value. Girls tend to present a higher fat percentage than boys. It was found that participants are not physically active as recommended by World Health Organization. This finding corroborates the results of physical activity levels found through the PAQ-C, between moderately active, sedentary and very sedentary. MC levels were classified below normal, more specifically with insufficient coordination and disturbance in coordination. These data were not relevant when compared to each other, however, there was a positive correlation, of low intensity, between the final score of the KTK test and the score of the PAQ-C. As for the KTK test, boys generally scored higher than girls in all tests. However, there was no significant difference between genders. There was a significant difference between the level of physical activity and the anthropometric variables only in the BMI. This difference was observed between the sedentary and moderately active. There was no correlation between the anthropometric variables and the PAQ-C result

The main objectives of this thesis are to determine if the addition of an energy wheel in an HVAC system can improve the indoor air relative humidity (RH), and perceived air quality (PAQ), as well as reduce energy consumption. An energy wheel is an air-to-air energy exchanger that transfers heat and moisture between the outdoor air entering and the exhaust air leaving a building. This thesis uses the TRNSYS computer package to model two buildings (an office and a school) in four different cities (Saskatoon, Saskatchewan; Vancouver, British Columbia; Tampa, Florida and Phoenix, Arizona).<p>The results with and without an energy wheel are compared to see if the energy wheel has a significant impact on the RH and PAQ in the buildings. The energy wheel reduces peak RH levels in Tampa, (up to 15% RH), which is a humid climate, but has a smaller effect on the indoor RH in Saskatoon (up to 4% RH) and Phoenix (up to 11% RH), which are dry climates. The energy wheel also reduces the number of people that are dissatisfied with the PAQ within the space by up to 17% in Tampa. <p>The addition of the energy wheel to the HVAC system creates a reduction in the total energy consumed by the HVAC system in Saskatoon, Phoenix and Tampa (2% in each city). There is a significant reduction in the size of the heating equipment in Saskatoon (26%) and in the size of the cooling equipment in Phoenix (18%) and Tampa (17%). A cost analysis shows that the HVAC system including an energy wheel has the least life-cycle costs in these three cities, with savings of up to 6%. In Vancouver, the energy wheel has a negligible impact on the indoor RH, PAQ and energy consumption.

With the proliferation of laptops, smart phones, sensors and other small devices, our physical environment is increasingly networked. Applications in a variety of problem domains (e.g., intelligent construction, traffic monitoring, smart homes, etc.) need to efficiently and seamlessly execute on top of such emerging infrastructure. Such infrastructure tends to be unreliable, and the network configuration changes constantly (network hosts depart and reemerge frequently). Consequently, software has to be able to react to these changes continuously and change its behaviors accordingly. In this dissertation, I introduce PAQ (Persistent Adaptive Query), a middleware designed to ease the programming burden associated with writing such applications. PAQ employs a novel style of query-driven application development that allows programmers to build pervasive applications by employing persistent queries--queries that continuously monitor the environment. The dissertation discusses the design and implementation of a new middleware model that allows programmers to write high level specifications abstracting away several tedious implementation details. PAQ employs both novel protocols that automatically tag the quality of information obtained from the network and statistical techniques to post-process and smooth the data. The goal of this research is to ease the software engineering challenges encountered during the construction and deployment of several applications in emerging pervasive computing environments thorough the use of a query-driven application development paradigm. / text

Anna Pavelková Title: Correlation of physical activity, motor skills and flat feet in children aged 7-15 years Objectives: The aim of the diploma thesis is to map the level of physical activity of selected age population of children that were indicated for physiotherapy, based on a questionnaire of physical activity PAQ-C. To monitor whether we find physical activity at levels 1 and 2 out (low physicalactivity)outof 5 levelspossible in children with flatfeet,on the basisof the PAQ- C questionnaire. Further objectify the flatfeet using a podoscope, and determine the level of the flatfeet according to Clement. Confirm / disprove the effect of the level of flatfeet on the achievement of the percentile (component and total) of the test battery MABC-2 in the evaluation of motor skills (especially balance and gross motor skills). Methods: A group of 15 children aged ± 10 years with diagnosed flatfeet (indicated for individual or group physiotherapy) formed a research sample for our study. Probands filled out an anamnestic questionnaire and a questionnaire on physical activity PAQ-C. Photographs of the plantogram of patients' were taken from the podoscope using a Huawei P9 Lite mobile camera (2017) placed on a tripod. The level of flatfeet was evaluated according to Clement based on the...
