Os prolapsos dos órgãos pélvicos (POP) apresentam alta prevalência na população feminina, causando um grande impacto social e econômico negativo. Cerca de 11,1% das mulheres aos 80 anos têm indicação para a cirurgia de reparação de POP ou incontinência urinária. Há evidências de que o tratamento conservador, especificamente o treinamento dos músculos do assoalho pélvico (TMAP) é eficaz na redução dos sintomas do POP. No entanto, a literatura é escassa e controversa em relação à efetividade em associar-se o TMAP a procedimento cirúrgico quando há indicação cirúrgica. O objetivo primário deste estudo foi avaliar a eficácia em associar-se o TMAP a procedimento cirúrgico para correção de POP em relação aos seus sintomas. Os objetivos secundários foram verificar a capacidade de contração dos músculos do assoalho pélvico (MAP), a intensidade da contração voluntária máxima (CVM) dos MAP, percepção de melhora, a qualidade de vida, e função sexual. Foi conduzido um ensaio clínico randomizado e controlado com 96 mulheres com indicação médica para a cirurgia de reparação de POP em estágios II, III e IV alocadas em dois grupos: 48 no grupo submetido ao TMAP e 48 no grupo controle. O TMAP foi realizado em quatro sessões supervisionadas pré-cirúrgicas e sete sessões no pós-operatório. Todas as voluntárias foram avaliadas em três momentos: 15 dias antes da cirurgia e 40 e 90 dias após a cirurgia. O desfecho primário foi avaliado por meio do \"Questionário de desconforto no assoalho pélvico\" (PFDI-20) e os secundários por meio da Escala de Oxford Modificada, perineometria, \"Escala de impressão clínica global de melhora\" (PGI-I) \"Questionário de impacto no assoalho pélvico\" (PFIQ-7) e \"Questionário sexual para incontinência urinária e prolapso de órgãos pélvicos\" (PSIQ-12). Os dados foram analisados pela estatística descritiva por meio de frequências e porcentagens. Utilizou-se o teste t Student para verificar a diferença entre as médias dos dois grupos. Já o teste qui-quadrado para testar a diferença entre as proporções nas respostas dos dois grupos. Um modelo de regressão linear misto foi utilizado para verificar o efeito do tempo e dos grupos em relação aos desfechos. O nível de significância adotado foi p<=0,05. Ambos os grupos apresentaram melhora na sintomatologia após o seguimento. No entanto, não houve diferença significativa entre eles (4,3 IC 95%-14,4 a 23,2, p=0,65). Ambos os grupos apresentaram melhora na capacidade de contração dos MAP. Após 3 meses, a diferença entre os grupos em relação CVM foi -0,8 (IC 95% -8,1 a 6,4, p=0,81), em relação à percepção de melhora foi 0,4 (IC 95% -0,09 a 0,8, p=0,01), à qualidade de vida foi 2,7 (IC 95% -19,5 a 24,9, p=0,81) e em relação à função sexual -1,6 (IC 95% -7,6 a 4,4, p=0,59). Este estudo não demonstrou benefício adicional do TMAP em relação à sintomatologia de POP, capacidade de contração dos MAP, CVM dos MAP, qualidade de vida e função sexual. Entretanto, o grupo que recebeu o TMAP apresentou maior percepção de melhora / Pelvic organ prolapse (POP) has a high prevalence in the female population, causing a great negative social and economic impact. It is estimated that about 11.1% of women at age 80 are eligible for POP repair surgery or urinary incontinence. There is evidence that conservative treatment, specifically pelvic floor muscle training (PFMT), is effective in reducing POP symptoms. However, the literature is scarce and controversial regarding the effectiveness in associating PFMT with a surgical procedure when there is a surgical indication. The primary purpose of this study was to evaluate the efficacy in associating PFMT to a POP surgery in relation to its symptoms. The secondary purposes were to verify the capacity of pelvic floor muscles\' contraction (PFM), the maximum voluntary contraction (MVC) of the PFM, perception of improvement, quality of life and sexual function. A randomised controlled trial with 96 women with a medical indication for POP repair surgery in stage II, III and IV was conducted in two groups: 48 in the TMAP and 48 in control group. TMAP was performed in four supervised preoperative sessions and seven postoperative sessions. All volunteers were evaluated in three moments: 15 days before surgery and 40 and 90 days after surgery. The primary outcome was assessed using the \"Pelvic Floor Distress Inventory\" (PFDI-20) and the secondary endpoints using the \"Modified Oxford Scale\", perineometry, \"Patient Global Impression of Improvement\" (PGI-I), \"Pelvic Floor Impact Questionnaire\" (PFIQ-7) and \"Sexual Questionnaire for Urinary Incontinence /Pelvic Organ Prolapse\" (PSIQ- 12) and. Data were analyzed by descriptive statistics using frequencies and percentages. Student\'s test was used to verify the difference between the means in the groups. The chi-square test was performed to test the hypothesis whether there was a difference between the proportions of responses in both groups. A mixed linear regression model was used to verify the effect of time and groups on outcomes. The level of significance was set at p<=0.05. Both groups presented improvement in the symptomatology after the follow-up. However, there was no significant difference between them (4.3 95% CI -14.4 to 23.2, p=0.65). Both groups showed improvement in PFM contraction. After 3 months, the difference between groups in relation to MVC was -0.8 (95% CI -8.1 to 6.4, p=0.81), in relation to the perception of improvement was 0.4 (95% CI -0.09 to 0.8, p = 0.01), in relation to the quality of life was 2.7 (95%CI, p=0.81) and in relation to sexual function -1.6 (95% CI -7.6 to 4.4, p = 0.59) and This study did not demonstrated the additional benefit of PFMT on POP symptoms, PFM contraction, MVC, quality of life and sexual function. However, the group that received TMAP showed a greater perception of improvement

An increased share of construction with timber is one possible way of achieving more sustainable and energy-efficient life cycles of buildings. The main reason is that wood is a renewable material and buildings require a large amount of resources. Timber buildings taller than two storeys were prohibited in Europe until the 1990s due to fire regulations. In 1994, this prohibition was removed in Sweden.     Some of the early multi-storey timber buildings were associated with more complaints due to impact sound than concrete buildings with the same measured impact sound class rating. Research in later years has shown that the frequency range used for rating has not been sufficiently low in order to include all the sound characteristics that are important for subjective perception of impact sound in light weight timber buildings. The AkuLite project showed that the frequency range has to be extended down to 20 Hz in order to give a good quality of the rating. This low frequency range of interest requires a need for knowledge of the sound field distribution, how to best measure the sound, how to predict the sound transmission levels and how to correlate numerical predictions with measurements.     Here, the goal is to improve the knowledge and methodology concerning measurements and predictions of low frequency impact sound in light weight timber buildings. Impact sound fields are determined by grid measurements in rooms within timber buildings with different designs of their joist floors. The measurements are used to increase the understanding of impact sound and to benchmark different field measurement methods. By estimating transfer functions, from impact forces to vibrations and then sound pressures in receiving rooms, from vibrational test data, improved possibilities to correlate the experimental results to numerical simulations are achieved. A number of excitation devices are compared experimentally to evaluate different characteristics of the test data achieved. Further, comparisons between a timber based hybrid joist floor and a modern concrete floor are made using FE-models to evaluate how stiffness and surface mass parameters affect the impact sound transfer and the radiation.     The measurements of sound fields show that light weight timber floors in small rooms tend to have their highest sound levels in the low frequency region, where the modes are well separated, and that the highest levels even can occur below the frequency of the first room mode of the air. In rooms with excitation from the floor above, the highest levels tend to occur at the floor levels and in the floor corners, if the excitation is made in the middle of the room above. Due to nonlinearities, the excitation levels may affect the transfer function in low frequencies which was shown in an experimental study. Surface mass and bending stiffness of floor systems are shown, by simulations, to be important for the amount of sound radiated.     By applying a transfer function methodology, measuring the excitation forces as well as the responses, improvements of correlation analyses between measurements and simulations can be achieved / ProWood / Silent Timber Build / Urban Tranquility / BioInnovation FBBB

Nowadays the attention to the utilization of secondary raw materials as a component of building materials is being paid to in the Czech Republic and in the world. This thesis deals with possibilities of using secondary raw materials as partial cement substitutes in industrial floors. The aim of this thesis is to verify the influence of cement substitution amount with secondary raw materials and their fineness of grinding on the properties of the floor surface in time and on its structure. On the basis of the acquired knowledge, the influence of the pre-treatment of the secondary raw material on the properties of the floor ceiling with an emphasis on the economic aspect was assessed. After evaluating the results, some substitution of cement in the floor screed with secondary raw materials is beneficial. The significant influence of more intensive milling of the floor screeds base on the parameters of the final floor screed was not confirmed. It seems, that it is possible to achieve very good results even when using secondary raw materials with a lower percentage of fine particles. This brings together the economic benefits of lowering the cost of a lower dose of expensive cement by using cheaper secondary raw materials, because pre-treatment of such materials does not require the use of a large amount of energy.
