Concepções e práticas de um centro de actividades ocupacionais

O presente trabalho tem como principal objectivo tentar conhecer e compreender as concepções educativas de um Centro de Actividades Ocupacionais face ao seu público-alvo em particular, as suas dimensões mais relevantes, os factores que as condicionam e os contextos que as limitam ou facilitam. Procurou-se conhecer as concepções e práticas dos actores educativos que intervêm na formação/educação junto de pessoas portadoras de deficiência mental adultas, clientes de um Centro de Actividades Ocupacionais, geograficamente situado em Lisboa. Para tal, elaborou-se um Estudo de Caso utilizando entrevistas semi estruturadas a sete profissionais do centro como técnica de recolha de dados, sendo estes posteriormente tratados através da análise de conteúdo. Assim, definiram-se como objectivos específicos do estudo: caracterizar as finalidades educativas do Centro de Actividades Ocupacionais; caracterizar as práticas de desenvolvimento para os adultos deficientes mentais; caracterizar o modo de participação dos clientes nas actividades: aspectos facilitadores e constrangimentos; identificar as dificuldades dos funcionários do Centro de Actividades Ocupacionais no atendimento aos clientes; caracterizar as iniciativas da instituição face à actualização profissional dos seus funcionários no sentido de fornecer respostas mais adequadas às necessidades dos clientes e, ainda, caracterizar de acordo com o ponto de vista dos actores educativos, a participação das famílias no processo de desenvolvimento dos clientes. Os resultados do estudo evidenciam que as actividades desenvolvidas no Centro de Actividades Ocupacionais se dividem entre as consideradas como socialmente úteis, como a montagem de material eléctrico, por exemplo, e as estritamente ocupacionais. Embora um dos objectivos do Centro de Actividades Ocupacionais seja a inserção do cliente na comunidade, da análise de dados ressalta que não existem muitas actividades que divulguem para o exterior o trabalho desenvolvido pelos adultos portadores de deficiência mental, promovendo pouca interacção dos indivíduos com a comunidade. As profissionais que participaram no estudo revelam motivação para trabalhar junto dos clientes e preocupação em melhorar o seu desempenho profissional, daí sentirem necessidade em adquirir formação contínua e partilhar experiências com outros profissionais. As famílias dos clientes são consideradas pelas participantes do estudo como sendo participativas no quotidiano do seu familiar, contudo existem factores que condicionam essa participação, como o envelhecimento dos progenitores. Abstract The present work aims to know and understand the educational conceptions of an Occupational Activities Center taking into consideration its target audience, particularly, its most relevant dimensions, the conditioning factors and its respective restrictive or facilitating contexts. The objective was to understand the concepts and daily practices of the educational actors that participate in the training/education of the mentally disabled adults who attend an Occupational Activities Center located in Lisbon. In that light, a Case Study was conducted using as the data collection technique semistructured interviews made to seven employees from the Center. This data was later on processed through content analysis. Thus, the following was defined as the study’s specific goals. To: characterize the educational purposes of the Occupational Activities Center; characterize development practices for the mentally disabled adults; characterize the clients’ participation process in the activities and the respective enabling and restrictive aspects; identify the Occupational Activities Center employees’ problems regarding client assistance; characterize the institution’s initiatives regarding the professional update of its employees in order to provide more adequate answers to its clients’ needs and, finally to identify from the educational actors’ perspective the participative role families’ take on when it comes to the clients’ development processes. The study results determine that the activities developed in the Occupational Activities Center are distinguished between the ones considered socially useful, such as the assembly of electric material, and the strictly occupational activities. Although one of the Occupational Activities Center goals is the insertion of the client within the community itself, the data analysis shows that there aren’t many activities that promote to the outside world the work performed by these mentally disabled adults, not advertising enough the individuals’ interaction with the community. The professional women who participated in the study show determination and motivation in working with the clients and also a concern in improving their professional performances, from this derives their need to attend continuous training and to share experiences with other professionals. The study's participants find the clients’ families involved in the daily routines of their relatives. Nonetheless, there are some factors that condition that involvement, such as the parents’ aging.

Effects of an exercise training program in physical condition after liver transplantation in familial amyloidotic polyneuropathy: a case report

Introduction: Familial amyloidotic polyneuropathy (FAP) is a neurodegenerative disease that leads to sensory and motor polyneuropathies as well as functional limitations. So far, liver transplantation is the only treatment for FAP because the mutated protein causing the disease is mainly produced in the liver. With the increasing survival of transplant recipients, functional and cardiovascular problems as consequences of immunosuppressant side effects are increasing associated with sedentary lifestyles and/or retransplantation status. We sought to analyze the impact of exercise training programs on 1 FAP patient’s course long-term after liver transplantation. Methodology. A FAP patient (female; 49 years of age; body mass index 18.8 kg/m2) underwent a liver transplantation 133 months before assessment. She was assessed for body composition, isometric quadriceps muscle strength, functional capacity, fatigue, and levels of physical activity before and after a 6-month period of combined exercise training. Results: After the exercise training program, almost all variables were improved, namely, total body skeletal muscle mass, proximal femoral bone mineral density, quadriceps strength, maximal oxygen consumption on 6 minutes walk test (6mwt) or VO2peak, total ventilation on 6mwt, and fatigue. The improvement in distance on 6mwt (69.2 m) was clinically significant. Preintervention the levels of physical activity were below international recommendations for health; after the program they achieved the recommendations. Conclusion: The results showed an improvement in functional capacity with a decrease in future disability risk associated with a better lifestyle with respect to physical activity levels in 1 patient.

New Technique for Uniform Voltage Sharing in Series Stacked Semiconductors

This paper describes the operation of a solid-state series stacked topology used as a serial and parallel switch in pulsed power applications. The proposed circuit, developed from the Marx generator concept, balances the voltage stress on each series stacked semiconductor, distributing the total voltage evenly. Experimental results from a 10 kV laboratory series stacked switch, using 1200 V semiconductors in a ten stages solid-state series stacked circuit, are reported and discussed, considering resistive, capacitive and inductive type loads for high and low duty factor voltage pulse operation.

The impact of exercise training on liver transplanted familial amyloidotic polyneuropathy (FAP) patients

Liver transplantation is nowadays the only effective answer to adjourn the outcome of functional limitations associated with familial amyloidotic polyneuropathy (FAP), a neurodegenerative disease characterized by sensory and motor polyneuropathies. Nevertheless, there is a detrimental impact associated with the after-surgery period on the fragile physical condition of these patients. Exercise training has been proven to be effective on reconditioning patients after transplantation. However, the effects of exercise training in liver transplanted FAP patients have not been scrutinized yet.

Radiographers and radiation protection: education, training and CPD

The increasing use of ionizing radiation for medical purposes emphasizes the concern about safety and justification of using ionizing radiation. This is linked with the use of new and high-dose X-ray technology (particularly CT). According to the UNSCEAR 2010 Report the total number of diagnostic medical examinations (both medical and dental) is estimated to have risen from 2.4 billion (period 1991–1996) to 3.6 billion (period 1997– 2008) - a marked increase in collective doses. An appropriate use of technology aiming diagnostic or therapy and respecting the ALARA principle is a mandatory requisite to safely perform any radiological procedure. Radiation protection is thus, a concern of all specialists in the radiology field ( radiologists, radiographers, medical physicists, among other professional groups). The importance of education and training of these professionals in reducing patients’ doses while maintaining the desired level of quality in medical exposures, as well as precise therapeutic treatments is well recognized. Education, training and continuing professional development (CPD) constitute a triad pointing towards the radiographers’ development of competences in the radiation protection field. This presentation excludes the radiographer role and competences in the fields of ultrasonography and MRI.

A model updating technique based on FRFs for damped structures

Model updating methods often neglect that in fact all physical structures are damped. Such simplification relies on the structural modelling approach, although it compromises the accuracy of the predictions of the structural dynamic behaviour. In the present work, the authors address the problem of finite element (FE) model updating based on measured frequency response functions (FRFs), considering damping. The proposed procedure is based upon the complex experimental data, which contains information related to the damped FE model parameters and presents the advantage of requiring no prior knowledge about the damping matrix structure or its content, only demanding the definition of the damping type. Numerical simulations are performed in order to establish the applicability of the proposed damped FE model updating technique and its results are discussed in terms of the correlation between the simulated experimental complex FRFs and the ones obtained from the updated FE model.

A hybrid MLS technique for room impulse response estimation

The measurement of room impulse response (RIR) when there are high background noise levels frequently means one must deal with very low signal-to-noise ratios (SNR). if such is the case, the measurement might yield unreliable results, even when synchronous averaging techniques are used. Furthermore, if there are non-linearities in the apparatus or system time variances, the final SNR can be severely degraded. The test signals used in RIR measurement are often disturbed by non-stationary ambient noise components. A novel approach based on the energy analysis of ambient noise - both in the time and in frequency - was considered. A modified maximum length sequence (MLS) measurement technique. referred to herein as the hybrid MLS technique, was developed for use in room acoustics. The technique consists of reducing the noise energy of the captured sequences before applying the averaging technique in order to improve the overall SNRs and frequency response accuracy. Experiments were conducted under real conditions with different types of underlying ambient noises. Results are shown and discussed. Advantages and disadvantages of the hybrid MLS technique over standard MLS technique are evaluated and discussed. Our findings show that the new technique leads to a significant increase in the overall SNR. (C) 2008 Elsevier Ltd. All rights reserved.

The influence of the blood pressure on the venous cerebral flow measured by magnetic susceptibility (SWI) technique

Susceptibility Weighted Image (SWI) is a Magnetic Resonance Imaging (MRI) technique that combines high spatial resolution and sensitivity to provide magnetic susceptibility differences between tissues. It is extremely sensitive to venous blood due to its iron content of deoxyhemoglobin. The aim of this study was to evaluate, through the SWI technique, the differences in cerebral venous vasculature according to the variation of blood pressure values. 20 subjects divided in two groups (10 hypertensive and 10 normotensive patients) underwent a MRI system with a Siemens® scanner model Avanto of 1.5T using a synergy head coil (4 channels). The obtained sequences were T1w, T2w-FLAIR, T2* and SWI. The value of Contrast-to-Noise Ratio (CNR) was assessed in MinIP (Minimum Intensity Projection) and Magnitude images, through drawing free hand ROIs in venous structures: Superior Sagittal Sinus (SSS) Internal Cerebral Vein (ICV) and Sinus Confluence (SC). The obtained values were presented in descriptive statistics-quartiles and extremes diagrams. The results were compared between groups. CNR shown higher values for normotensive group in MinIP (108.89 ± 6.907) to ICV; (238.73 ± 18.556) to SC and (239.384 ± 52.303) to SSS. These values are bigger than images from Hypertensive group about 46 a.u. in average. Comparing the results of Magnitude and MinIP images, there were obtained lower CNR values for the hypertensive group. There were differences in the CNR values between both groups, being these values more expressive in the large vessels-SSS and SC. The SWI is a potential technique to evaluate and characterize the blood pressure variation in the studied vessels adding a physiological perspective to MRI and giving a new approach to the radiological vascular studies.
