Abstract:
This study presents a novel active vibration control (AVC) system on motor driven power steering (MDPS) to reduce interior noise reduction caused by operating the MDPS in an electric vehicle. MDPS is electronic power steering (EPS). The MDPS attached to the rack gear of power steering system is called R-MDPS. Operating of the R-MDPS generates a structural vibration of R-MDPS, and the vibration is transmitted to car body through mounts of car subframe. The vibrating body of car becomes a monopole and dipole sources of vibroacoustic noise generated inside car. This vibracoustic noise is a structure borne noise and makes passenger annoyance. To reduce interior noise inside a car directly, active noise control (ANC) has been used as active method and is a useful method for active cancellation of the low frequency noises less than 400Hz. However, in this study, because the frequency range of interior noise due to operation of R-MDPS is higher than 400Hz, the AVC system is employed and is applied to active cancellation of the vibration transmitted to car body through the subframe mounts. For application of AVC to test car, the control force is required and the actuator for generation of control force should be install on the mounts. For application of AVC to test car, the control force is required and the actuator for generation of control force should be inserted in the mount between subframe and R-MDPS. It requires an extra rework of test car. In this study to study the feasibility for the application of AVC system to R-MDPS, the test jig, which composes of R-MDPS and subframe of test car, is made and is set up in the laboratory. All study on AVC is performed in the laboratory. The proposed method is successfully applied to the active cancellation of vibration at target point of subframe. The developed method is going to be applied to the AVC of real test vehicle.

Abstract:
Abstract Objective The aim of this work was to study serum sclerostin levels in patients with chronic kidney disease (CKD) not on dialysis and those on regular hemodialysis and its role in vascular calcification. Background CKD, whether starting hemodialysis (HD) or not, is associated with an increase in the risk for vascular calcification, which can only be partially explained by known classical risk factors. Sclerostin is an osteocyte-derived inhibitor of the Wnt pathway and has been shown to play a key role in vascular calcification in patients with CKD. Patients and methods This cross-sectional study was carried out on 80 patients with CKD attending Menoufia University Hospital. Patients were classified into 40 patients with CKD who were not on HD (group I) and 40 patients with CKD on regular HD more than 6 months (group II), who were compared with 15 controls (group III). Abdominal aortic calcification (AAC) was assessed using lateral lumbar radiography. Echocardiography was used to assess aortic valve calcification (AVC) calcification. Patient’s basic clinical and biochemical data were recorded. Serum sclerostin level was measured using commercially available enzyme-linked immunosorbent assay kits. Results Sclerostin levels among the patients with CKD on HD (116.8±0.103.69 Pmol/l) was significantly higher than that of CKD predialysis group (28.63±0.36.26 Pmol/l), which in turn was statistically higher than control group (6.6±0.2.9 Pmol) (P=0.000). AAC was observed in 16 (40%) patients in CKD predialysis group, whereas in CKD on HD group, 26 (65%) patients had AAC. AVC was observed in 14 (35%) patients in CKD predialysis group, whereas in CKD on HD group, 21 (52.5%) patients had AVC. Using binary regression analysis, sclerostin was identified as an independent predictor for the presence of AAC (OR: 1.017; P=0.000) and AVC (OR: 1.013; P=0.001) in patients with CKD. Conclusion Patients with CKD (predialysis and on HD) exhibit an increase in sclerostin levels. Sclerostin expansion correlated positively with vascular and valvular calcification. Sclerostin is an independent risk factor for heart valve calcification and AAC in patients with CKD.

Abstract:
Introduction: A link between full blood count (FBC) parameters with the severity and prognosis of individuals with coronavirus disease 2019 (COVID-19) infection is shown. We aim to identify changes in FBC parameters depending on patients’ characteristics, the severity of the disease and vaccination status. Methods: A cross-sectional retrospective laboratory study is done on 208 respondents who were selected from February 2021 to December 2022 in the Pathology Department of the Tuanku Ja’afar Hospital in Negeri Sembilan. All patients are confirmed COVID-19 positive by real-time reverse transcriptase-polymerase chain reaction (RT-PCR) of pharyngeal and nasal swab specimens. Patients are further classified based on their COVID clinical stages, severity, vaccination status and outcome. The statistical data are analysed using IBM SPSS version 27. Results: Severe patients have significantly lower absolute lymphocyte count (ALC), absolute monocyte count (AMC), absolute eosinophil count (AEC) and absolute basophil count (ABC) but higher mean platelet volume (MPV), absolute neutrophil count (ANC), neutrophil to lymphocyte ratio (NLR) and immature granulocytes (IG) compared to non-severe patients (p < 0.05). Similar findings are seen among non-survivors (p < 0.05). Fully vaccinated patients have significantly lower NLR and MPV but higher ALC, AMC, AEC and ABC than unvaccinated or partially vaccinated patients (p < 0.05). Conclusion: Selected FBC parameters of COVID-19 patients (platelets, ANC, NLR, MPV, ALC, AMC, AEC, and ABC) are significantly different depending on patients’ severity, outcome and vaccination status. These results might give a clear insight for clinicians to anticipate the severity and outcome of patients based on the patient’s FBC parameters.

Abstract:
O Acidente Vascular Cerebral (AVC) é uma condição médica crítica caracterizada pela interrupção súbita do fluxo sanguíneo para uma parte do cérebro, resultando em danos neurológicos que podem variar em severidade. A definição moderna do AVC evoluiu com os avanços na neuroimagem e na compreensão patofisiológica, que agora permitem distinguir de maneira mais precisa entre AVC isquêmico e hemorrágico. A revisão sistemática envolveu uma análise detalhada de estudos selecionados com base em critérios rigorosos e uma estratégia abrangente de busca em bases de dados acadêmicas. Essa abordagem meticulosa permitiu a extração e avaliação minuciosa dos dados, com o objetivo de sintetizar as tendências atuais e identificar lacunas na literatura. Tradicionalmente, o AVC é definido pela Organização Mundial da Saúde (OMS) como uma síndrome clínica com sintomas neurológicos focais. No entanto, a definição moderna incorpora o uso de técnicas de neuroimagem para diferenciar entre AVC isquêmico, resultante de infarto cerebral devido a obstrução do fluxo sanguíneo, e AVC hemorrágico, causado por sangramentos no cérebro. Globalmente, o AVC continua a ser uma das principais causas de mortalidade, com alta prevalência no Brasil, onde é a principal causa de morte. A patogênese do AVC inclui diversos mecanismos, como infarto lacunar, aterotrombótico e cardioembólico, enquanto a hemorragia subaracnóidea frequentemente resulta da ruptura de aneurismas. O diagnóstico do AVC envolve uma combinação de avaliação clínica e técnicas de neuroimagem para confirmar o tipo de AVC e orientar o tratamento. As estratégias de tratamento variam de acordo com o tipo de AVC: o AVC isquêmico pode ser tratado com trombólise e controle rigoroso da pressão arterial, enquanto o AVC hemorrágico e a hemorragia subaracnóidea exigem abordagens específicas para controlar o sangramento e tratar suas causas subjacentes. A revisão sistemática destaca a necessidade de estratégias eficazes de prevenção e tratamento, assim como a importância de políticas de saúde pública e pesquisa contínua para melhorar os resultados clínicos e a qualidade de vida dos pacientes. O AVC isquêmico é predominante, exigindo atenção especial para aterosclerose e embolias cardiogênicas, enquanto a hemorragia subaracnóidea e cerebral demanda monitoramento rigoroso e manejo especializado.

Abstract:
Background. Aortic valve calcification (AVC) is a common feature of aging and is related to coronary artery disease. Although abdominal visceral adipose tissue (VAT) plays fundamental roles in coronary artery disease, the relationship between abdominal VAT and AVC is not fully understood.Methods. We investigated 259 patients who underwent cardiac and abdominal computed tomography (CT). AVC was defined as calcified lesion on the aortic valve by CT. %abdominal VAT was calculated as abdominal VAT area/total adipose tissue area.Results. AVC was detected in 75 patients, and these patients showed higher %abdominal VAT (44% versus 38%,p<0.05) compared to those without AVC. When the cutoff value of %abdominal VAT was set at 40.9%, the area under the curve to diagnose AVC was 0.626. Multivariable logistic regression analysis showed that age (OR 1.120, 95% CI 1.078–1.168,p<0.01), diabetes (OR 2.587, 95% CI 1.323–5.130,p<0.01), and %abdominal VAT (OR 1.032, 95% CI 1.003–1.065,p<0.05) were independent risk factors for AVC. The net reclassification improvement value for detecting AVC was increased when %abdominal VAT was added to the model: 0.5093 (95% CI 0.2489–0.7697,p<0.01).Conclusion. We determined that predominance of VAT is associated with AVC.

Abstract:
Introdução: O acidente vascular cerebral hemorrágico pela sua epidemiologia, e pelos seus altos índices de mortalidade, exige uma resposta rápida e incisiva para que os doentes recebam o melhor tratamento possível. Para que a resposta seja efectiva, há que reconhecer os factores de risco e os factores passíveis de alterar a mortalidade precoce (primeira semana) por esta causa. Foi neste sentido que o estudo foi desenhado, para identificar factores de risco passíveis de alterar o resultado final perante doentes com acidente vascular cerebral hemorrágico, dando especial atenção ao volume inicial de hemorragia e edema como factores de mau prognóstico. Métodos: Recolheram-se os dados do suporte informático da tomografia computorizada crâneo-encefálica de entrada e dos processos clínicos dos doentes internados na Unidade de Acidentes Vasculares Cerebrais do Hospital Pêro da Covilhã entre o dia 1 de Setembro de 2007 e o dia 31 de Agosto de 2008. Resultados: O estudo envolveu 45 doentes, 33 destes sobreviveram e 12 resultaram em óbito. A mortalidade deste grupo de estudo foi de 26,7%. Os doentes que faleceram apresentaram um valor médio de volume de hemorragia de 31,4cc, enquanto os restantes doentes tinham um valor médio de 15,7cc. O valor médio de volume de edema nos doentes que faleceram foi de 31,4cc, e nos outros doentes a média foi de 12,8cc. Discussão: Maior volume inicial de edema nas primeiras 24 horas está associado a risco independente de mortalidade precoce por acidente vascular cerebral hemorrágico. Contagem de plaquetas e nível aumentado de glicemia à admissão hospitalar, bem como história de diabetes mellitus, de fibrilhação auricular e de uso prévio de medicação antiagregante, estão também independentemente associados a pior prognóstico.
Introduction: Taking into account hemorrhagic stroke epidemiology, and its high mortality rate, a quick and incisive response is needed so that patients can receive the best possible treatment. In order to do so, it’s vital to recognize risk factors and the factors that can alter early death (first week) in this context. This study was designed to respond to that need, to identify risk factors capable of altering the outcome of hemorrhagic stroke patients, with special attention given to initial hemorrhagic volume and initial oedema volume as poor prognostic factors. Methods: The data was collected from the digital support of the cranial computerized tomography and from the clinical records of the patients admitted on “Unidade de Acidentes Vasculares” of Pêro da Covilhã Hospital between September 1, 2007 and October 31, 2008. Results: The study included 45 patients, 33 of which survived and 12 died. The mortality of the group was 26,7%. The patients that died showed a mean volume of haemorrhage of 31,4cc, while the others stayed with a mean volume of 15,7cc. The mean value for oedema volume in the deceased patients was 31,4cc, and 12,8 in the ones who survived. Discussion: Higher volume of oedema in the first 24 hours is associated with independent risk for early mortality following hemorrhagic stroke. Platelet count and higher glucose level on admission, as well as history of diabetes mellitus, atrial fibrillation and prior use of antiplatelet agents are also independently associated with worst prognosis.

Abstract:
Introdução: Os Acidentes Vasculares Cerebrais são um grave problema de saúde pública em Portugal e em todo o mundo. Níveis elevados de glicose no sangue são comuns na fase inicial do AVC. A prevalência de hiperglicémia, definida como o nível de glicose no sangue >6,0mmol/L (108mg/dl), foi observada em mais de 50% dos pacientes, independentemente do subtipo de acidente vascular cerebral. Este trabalho pretende estudar a relação entre os níveis de glicemia na admissão e o prognóstico à alta dos doentes com o diagnóstico de AVC. Secundariamente, pretende estudar a relação entre o prognóstico destes doentes com outras variáveis. Métodos: Realizou-se um estudo retrospectivo dos pacientes internados na U-AVC do CHCB com o diagnóstico de AVC. Os dados colhidos são referentes aos pacientes internados no período compreendido entre 1 de Junho de 2009 e 30 de Maio de 2010. Para a recolha de dados (níveis de glicémia capilar, HbA1c, PCR, fibrinogénio e D-dímeros medidos na admissão, pontuação da escala de NIHSS admissão, bem como pontuação na ER e IB à alta), procedeu-se à consulta dos processos clínicos. Resultados: Estudaram-se 297 pacientes sendo que 31,3% eram diabéticos e 73,7% apresentavam valores de glicémia superiores aos considerados normais. Em relação aos pacientes com Hiperglicémia na admissão, 19 faleceram e 114 foram classificados como dependentes enquanto que dos pacientes sem Hiperglicémia na admissão, 2 faleceram e 34 foram classificados como dependentes. As relações entre Hiperglicémia na admissão com a mortalidade e com o prognóstico não foram estatisticamente significativas (p=0,71 e p=0,199, respectivamente). Conclusão: Os resultados deste trabalho sugerem que tanto a hiperglicémia na admissão como a própria Diabetes sejam achados frequentes na população vítima de AVC. Os pacientes com Hiperglicémia na admissão apresentaram uma maior mortalidade e um pior prognóstico (maior número de pacientes classificados como dependentes).
Introduction: Stroke is a serious public health problem in Portugal and the entire world. High levels of glucose in the blood are common in the early phase of stroke. The prevalence of hyperglycemia, defined as a level of blood glucose >6.0mmol/L (108mg/dl) was observed in more than 50% of patients, regardless of the subtype of stroke. The main aim of this work was to evaluate the relationship between blood glucose levels on admission and prognosis on discharge in patients with diagnosis of stroke. The secondary aim was to study the relationship between the prognoses of these patients with other variables. Methods: We conducted a retrospective study of patients admitted to the CHCB’s U-Stroke with the diagnosis of stroke. The study took place during the period from June 1, 2009 and May 30, 2010. To collect data (level of blood glucose, HbA1c, CRP, fibrinogen and D-dimmers measured on admission, the score of NIHSS on admission and also, the scores of Barthel Index and Rankin Scale on discharge), we proceeded to query clinical processes. Results: We studied 297 patients. The 31.3% were diabetic and the 73.7% had blood glucose levels above the values considered normal. Nineteen patients with hyperglycemia on admission died and 114 were dependent. However 2 patients without hyperglycemia on admission died and 34 were dependent. The relationship between hyperglycemia on admission with dependence and mortality was not statistically significant (p=0.71 and p=0.199, respectively). Conclusion: These results suggest that hyperglycemia on admission and Diabetes are a common finding in stroke patients. Patients with hyperglycemia on admission had a higher mortality and a worse prognosis (higher number of patients classified as dependent) compared with patients without hyperglycemia on admission.

Abstract:
Introdução: Ser um sobrevivente de um Acidente Vascular Cerebral (AVC) é uma realidade pessoal, económica e social que leva a uma reflexão sobre quais os tratamentos de reabilitação, recursos existentes e custos envolvidos, na realidade portuguesa comparando com outras. Assim, a evidência proveniente de revisões sistemáticas e trabalhos de investigação sobre esta temática demonstra que existem várias opções com evidência efetiva de serem custo-efetivas, não havendo no entanto consenso na comunidade científica em todos os pontos. Objetivos: A perceção de quais os tratamentos de reabilitação, estratégias e recursos disponíveis, assim como os custos envolvidos, na população portuguesa e em outras realidades, percebendo na revisão sistemática da literatura quais os fatores neste âmbito que se tornam efetivos e produtores de outcomes. Material e Métodos: A pesquisa foi efetuada nas bases RIHUC, B-on, Cochrane Database, Evidence-Based Medicine, Web of Science, Medline, E-Books e E-Journals. Tal conhecimento foi cruzado com a experiência da prática de reabilitação de doentes com AVC. Pesquisa efetuada de artigos posteriores a 1997 até 2012, em metanálises e estudos randomizados retrospetivos e prospetivos. Critérios de seleção: Estudos de investigação com resultados acerca de tratamentos, planos e recursos de reabilitação, que mostrem boa relação custo-eficácia, nos doentes sobreviventes a um Acidente Vascular Cerebral. Foram ainda incluídos um pequeno número de artigos que descrevem as práticas em algumas instituições. Resultados: Na identificação dos tratamentos e planos de Reabilitação aos doentes com AVC, encontrou-se forte evidência científica de que os planos efetuados por equipas pluriprofissionais e intensivos, têm ganhos na independência funcional dos doentes. Não se encontrando tratamentos nem planos sistematizados e guidelines de reabilitação, como se esperava. Nos recursos, as Unidades de AVC demonstram ser custo eficazes, pois apesar de despenderem elevados recursos, diminuem a mortalidade e a institucionalização. Na avaliação dos custos, os resultados não são completos, apenas identificando uma parte. Conclusões: As sequelas de AVC variam consoante o tipo de AVC, o local afetado e a extensão, sendo estas as variáveis que definem o plano de Reabilitação a seguir, diferente de doente para doente. Os recursos indicados como a melhor opção custo-eficácia, variando entre a UAVC, as equipas multidisciplinares em internamento ou ao domicílio. Variando assim, os outcomes obtidos e os custos despendidos. Nem todas as questões da reabilitação nos doentes de AVC têm resposta em estudos de investigação, pois existem fatores pessoais de cada indivíduo, doente, cuidador e profissional, que podem ser variáveis que alteram todo o processo, assim tornando difícil optar pelos que representam o melhor “Value for Money”. No futuro estas e outras questões necessitam de respostas baseadas em investigação efetuada com base na evidência das práticas.

Mestrado , Enfermagem de Reabilitação, 2013, Escola Superior de Enfermagem de Lisboa
O aumento da esperança de vida, a diminuição da mortalidade e o decorrente aumento do envelhecimento da população portuguesa traduz-se no aumento do número de pessoas com Acidente Vascular Cerebral (AVC), sendo atualmente em Portugal a principal causa de morte e de incapacidade tendo as suas sequelas grande impacto na dinâmica de vida da pessoa, confrontando-se esta com um súbito défice no autocuidado na realização das Atividades de Vida Diária (AVD). Tornando-se cada vez mais premente uma resposta eficaz por parte dos profissionais de saúde, onde se insere a intervenção especializada do enfermeiro de reabilitação. Por todo o impacto que esta patologia tem na sociedade atual e na minha práxis, esta problemática constituiu um foco de interesse e motivação. Sendo a hemiplegia ou hemiparesia a alteração mais manifesta do AVC, traduzindo-se num compromisso no autocuidado das AVD, das quais se destacam a higiene e vestuário, defini como objetivo central a desenvolver no estágio “promover o autocuidado da pessoa com AVC nas atividades de vida diária de higiene e vestuário”. Constituiu-se como fundamental a compreensão das principais dificuldades enfrentadas no internamento pela pessoa com AVC, de entre as quais as que se prendem com a realização das referidas AVD. Esta identificação das principais condicionantes para o autocuidado, permitem ao enfermeiro de reabilitação através de um processo educativo, dinâmico, continuo e progressivo, no qual se destaca a centralidade do utente nas decisões, a adequação dos cuidados ao contexto domiciliário da pessoa, a individualidade dos mesmos, o estudo da inclusão de possíveis produtos de apoio e o envolvimento precoce da família no processo de cuidados visando um planeamento de alta atempado, promover o autocuidado da pessoa. Tendo como principal objetivo da sua recuperação funcional, a reintegração na família, comunidade e sociedade, tendo as suas intervenções especializadas um papel essencial na limitação do impacto da incapacidade da pessoa com AVC.

Abstract:
INTRODUÇÃO: A Diabetes mellitus é uma entidade patológica que atinge 171 milhões de pessoas em todo o mundo, prevendo-se 330 milhões de doentes em 2030. De entre as suas inúmeras complicações conhecidas, as doenças macrovascular e microvascular são objecto crescente de estudo. O acidente vascular cerebral é uma das principais causas de morte nos países desenvolvidos. No entanto, existem ainda poucos estudos que relacionem estas duas entidades, no que à patogénese de doença vascular pela Diabetes mellitus diz respeito, e da sua relação com o tipo de acidente vascular cerebral e com o seu mecanismo específico. OBJECTIVO: O objectivo deste estudo é caracterizar o perfil de risco e o perfil de acidente vascular cerebral de doentes diabéticos, em contraponto com doentes não-diabéticos. MÉTODO: A presente investigação é um estudo retrospectivo. A amostra corresponde aos doentes que sofreram um acidente vascular cerebral no ano de 2008 e que recorreram ao Centro Hospitalar Cova da Beira, tendo ficado internados na unidade de acidente vascular cerebral. Os dados foram recolhidos da base de dados e dos processos clínicos e analisados estatisticamente. Foram analisados o perfil de risco e o perfil de acidente vascular cerebral, dividindo a amostra consoante o tipo de acidente vascular cerebral (isquémico/hemorrágico) e a presença/ausência de Diabetes mellitus. RESULTADOS: Os diabéticos apresentaram apenas acidente vascular cerebral isquémico, revelando um perfil com tendência a dislipidémia, a hiperglicemia crónica, hipertensão arterial e cardiopatia isquémica. O mecanismo mais frequente foi o de causa indeterminada (42,55%), seguido do lacunar (21,28%) e do aterotrombótico (19,15%). Os não-diabéticos revelaram um perfil com tendência dislipidémica, de hipertensão arterial e de fibrilhação auricular. O mecanismo mais frequente de acidente vascular cerebral isquémico foi o cardioembólico (41,67%). Os não-diabéticos com acidente vascular cerebral hemorrágico revelaram uma grande frequência relativa de hipertensão arterial e hábitos alcoólicos, sem outros factores de risco relevantes. CONCLUSÃO: Os diabéticos apresentaram apenas acidente vascular cerebral isquémico, com os mecanismos de causa indeterminada e de doença macro e microvascular a serem os mais importantes. Os não-diabéticos apresentaram acidente vascular cerebral isquémico (com o mecanismo cardioembólico a ser o mais preponderante) e hemorrágico (com a hipertensão arterial a constituir o principal factor de risco detectado).
INTRODUCTION: 171 millions around the world are affected by Diabetes mellitus, with an expectance of 330M in 2030. Diabetes mellitus causes many complications, but macro and microvascular diseases are growing in interest and study. Stroke is one of the main causes of death around the world. This data confirms the crucial importance of the investigation of these pathologies, as well as of their relationship. Nevertheless, few studies evaluate this association. GOAL: The goal of this study is to characterize the risk profile for stroke in diabetic patients who had suffered stroke and their stroke profile. METHODS: This study is a retrospective one. The sample was integrated by patients admitted to stroke unity of Centro Hospitalar Cova da Beira with diagnosis of stroke in 2008. Data was obtained from the stroke unity database and from the patients’ files. Statistic analysis of data was made. Several cardiovascular risk factors were analyzed, as well as the stroke profile. The sample was divided by the type of stroke (ischemic/hemorrhagic) and by the presence/absence of Diabetes mellitus. RESULTS: There were diabetic patients only in the ischemic stroke group. All hemorrhagic strokes belonged to non-diabetic subjects. The diabetic group revealed a dyslipidemia tendency, chronic hyperglycemia, arterial hypertension and ischemic heart disease. The most frequent mechanism was the undetermined cause (42,55%) followed by the small (21,28%) and the large (19,15%) arteries diseases mechanisms. Non-diabetic group revealed dyslipidemia, arterial hypertension and atrial fibrillation. The most frequent mechanism was cardioembolism (41,67%). The non-diabetic hemorrhagic group showed higher frequency of arterial hypertension and alcohol consumption, with no other relevant risk factors. CONCLUSION: The diabetic group suffered only ischemic strokes. The most important mechanisms were undetermined cause and both large and small artery disease. The non-diabetic ischemic group presented a different main stroke mechanism: cardioembolic. The non-diabetic hemorrhagic group presented arterial hypertension as the main risk factor.

Abstract:
The present thesis addresses the MPEG-4 AVC stream watermarking and considers two theoretical and applicative challenges, namely ownership protection and content integrity verification.From the theoretical point of view, the thesis main challenge is to develop a unitary watermarking framework (insertion/detection) able to serve the two above mentioned applications in the compressed domain. From the methodological point of view, the challenge is to instantiate this theoretical framework for serving the targeted applications. The thesis first main contribution consists in building the theoretical framework for the multi symbol watermarking based on quantization index modulation (m-QIM). The insertion rule is analytically designed by extending the binary QIM rule. The detection rule is optimized so as to ensure minimal probability of error under additive white Gaussian noise distributed attacks. It is thus demonstrated that the data payload can be increased by a factor of log2m, for prescribed transparency and additive Gaussian noise power. A data payload of 150 bits per minute, i.e. about 20 times larger than the limit imposed by the DCI standard, is obtained. The thesis second main theoretical contribution consists in specifying a preprocessing MPEG-4 AVC shaping operation which can eliminate the intra-frame drift effect. The drift represents the distortion spread in the compressed stream related to the MPEG encoding paradigm. In this respect, the drift distortion propagation problem in MPEG-4 AVC is algebraically expressed and the corresponding equations system is solved under drift-free constraints. The drift-free shaping results in gain in transparency of 2 dB in PSNR

Abstract:
La présente thèse aborde le sujet de tatouage du flux MPEG-4 AVC sur ses deux volets théoriques et applicatifs en considérant deux domaines applicatifs à savoir la protection du droit d’auteur et la vérification de l'intégrité du contenu. Du point de vue théorique, le principal enjeu est de développer un cadre de tatouage unitaire en mesure de servir les deux applications mentionnées ci-dessus. Du point de vue méthodologique, le défi consiste à instancier ce cadre théorique pour servir les applications visées. La première contribution principale consiste à définir un cadre théorique pour le tatouage multi symboles à base de modulation d’index de quantification (m-QIM). La règle d’insertion QIM a été généralisée du cas binaire au cas multi-symboles et la règle de détection optimale (minimisant la probabilité d’erreur à la détection en condition du bruit blanc, additif et gaussien) a été établie. Il est ainsi démontré que la quantité d’information insérée peut être augmentée par un facteur de log2m tout en gardant les mêmes contraintes de robustesse et de transparence. Une quantité d’information de 150 bits par minutes, soit environ 20 fois plus grande que la limite imposée par la norme DCI est obtenue. La deuxième contribution consiste à spécifier une opération de prétraitement qui permet d’éliminer les impactes du phénomène du drift (propagation de la distorsion) dans le flux compressé MPEG-4 AVC. D’abord, le problème a été formalisé algébriquement en se basant sur les expressions analytiques des opérations d’encodage. Ensuite, le problème a été résolu sous la contrainte de prévention du drift. Une amélioration de la transparence avec des gains de 2 dB en PSNR est obtenue

Abstract:
L’accident vasculaire cérébral (AVC) peut entraîner d’importantes séquelles, notamment au niveau cognitif. De plus, il est très fréquent que les victimes d’AVC souffrent de troubles du sommeil. À ce sujet, de nombreuses études ont démontré le rôle crucial du sommeil pour les fonctions cognitives, par exemple au niveau de la consolidation de la mémoire et des capacités attentionnelles. De plus, des chercheurs ont démontré qu’après un AVC, les fonctions cognitives sont améliorées conjointement à l’augmentation de la qualité du sommeil, de la phase aiguë à celle de récupération (Siccoli, Rolli-Baumeler, Achermann, & Bassetti, 2008). Or, ces données concernent des sujets d’âge moyens, ce qui donne peu d’informations sur la population la plus à risque de subir un AVC, soit les personnes âgées. Ainsi, les objectifs du présent projet de recherche sont d’une part de décrire les modifications dans le temps des paramètres de sommeil et de cognition en phase de réadaptation post-AVC chez des personnes âgées, et d’autre part de vérifier la relation entre les modifications de la qualité du sommeil et de la cognition chez ces personnes. Pour ce faire, un groupe de huit sujets âgés, hospitalisé à l’unité de réadaptation fonctionnelle intensive (URFI) du CSSS-IUGS, a participé à l’étude. Leur sommeil et leur cognition ont été évalués à deux temps de mesure : tout d’abord lors de leur admission à l’URFI, en moyenne 14 jours après leur AVC, et ensuite à la fin de leur séjour en réadaptation, en moyenne 33 jours après le premier temps de mesure. Leur sommeil a été évalué à l’aide de l’actigraphie et leur cognition à l’aide d’une batterie de tests neuropsychologiques. Les résultats actigraphiques démontrent tout d’abord que la qualité du sommeil des sujets ne s’est pas améliorée de manière significative dans le temps. Au niveau de la cognition, la mémoire, l’attention, le langage et les fonctions exécutives se sont améliorés de manière significative entre les deux temps de mesure. De plus, les résultats pointent vers une corrélation encore inédite entre l’amélioration de la qualité de sommeil et l’amélioration de la cognition dans le temps, selon la latérisation de l’AVC. En dépit du caractère exploratoire des ces résultats en raison du petit nombre de sujets dans chacun des sous-groupes (AVC gauche et AVC droit), il ressort que : a) chez les sujets ayant subi un AVC droit, plus la diminution des éveils après endormissement est importante du T1 au T2, meilleure est la récupération de la cognition globale, et que b) chez les sujets ayant subi un AVC gauche, plus la diminution des éveils après endormissement est importante du T1 au T2, meilleure est la mémoire épisodique. Ces résultats démontrent l’importance d’un sommeil de qualité dans la récupération cognitive des personnes âgées ayant subi un AVC. Ils démontrent de plus qu’une importante récupération cognitive est possible après un AVC, malgré un âge avancé. Ainsi, il apparaît très pertinent de traiter les troubles du sommeil des patients âgés après un AVC.

Abstract:
AbstractClimate change contributes significantly to the looming food insecurity in the rain-fed agricultural countries of Africa, including Nigeria. There is a gender dimension in climate change impacts and adaptation strategies along Agriculture Value Chain (AVC) in Nigeria. The chapter gender analyzed the aspects of climate change impacts; identified the indigenous and expert-based artificial adaptation strategies; assessed the gender differences in the adaptation strategies; and provided the gender implications of the indigenous adaptation strategies among actors along the AVC. The chapter adopted a value chain-based exploratory design with gender analysis as the narrative framework with Gender Response Theory as the theoretical background. There were gender differences in the production, economic, and social dimensions of the climate change impacts along the AVC. The indigenous climate change adaptation strategies were availability, low cost, and easily accessible; hence they were popularly adopted by male and female AVC actors. The adopted indigenous adaptation strategies challenged the social relations, influenced reordering of social and gender relations, participation, and power relation among the male and female actors along the AVC.

Abstract:
Introduction: Cannabis is frequently used to cope with anxiety symptoms (Sexton et al., 2016). Unfortunately, individuals with anxiety are also at greater risk for developing probable cannabis use disorder (CUD; Marel et al., 2019), although mechanisms are not well understood. Previous literature suggests avoidant coping styles (AVC) are associated with higher anxiety levels, whereas action oriented coping styles (AOC) are associated with lower anxiety levels (Ribadier & Varescon, 2019). While cannabis coping motives are a significant predictor of probable CUD for those with anxiety (Buckner & Zvolensky, 2014), no research has identified how anxiety and specific coping styles predict probable CUD. The aim of the present study was to determine how AVC and AOC interact with anxiety to predict the presence of probable CUD. It was hypothesized that overall individuals with high anxiety would be more likely to endorse probable CUD than low anxiety. Among both anxiety levels, AVC would be more likely to have probable CUD than those with low AVC. Furthermore, individuals with high anxiety and high AOC would be less likely to have probable CUD, compared with those with low AOC, even when anxiety is high. Methods: College students (N = 371; 72.2% female) who used cannabis in the past six months were recruited as part of a study examining the influence of cannabis use on academic success. Participants completed self-report measures to assess anxiety (DASS-21), coping (B-COPE), and probable CUD (CUDIT-R). A confirmatory factor analysis was used to derive coping subscales using items from the B-COPE (Grosso et al., 2014). Results: The data was analyzed through a logistic regression conducted in HAYES Process Macro. Even after controlling for gender, anxiety (b = .032, SE = .016, p = .046) was a positive significant predictor of probable CUD, however neither AOC (b = .030, SE = .025, p = .221) or AVC (b = .048, SE = .056, p = .392) were significant predictors of probable CUD. The interaction between Anxiety X AVC on probable CUD was significant (b = -.011, SE = .005, p = .026), indicating that those with low anxiety and high AVC were more likely to have probable CUD than those with low anxiety and low AVC; however, this interaction did not apply when anxiety levels were high. The interaction between AOC and anxiety was not significant (b = .004, SE = .003, p = .134), which did not support our initial hypothesis. Discussion: Even when anxiety levels are low, individuals with higher AVC are more likely to endorse probable CUD. In contrast, individuals with higher anxiety are more likely to exhibit probable CUD, regardless of AVC levels. Interestingly, anxiety and AOC did not interact to predict probable CUD, suggesting that risk for CUD may be more about what people avoid than what they do to actively cope. These findings emphasize the importance of targeting both anxiety and AVC when considering risk for probable CUD. Longitudinal data are needed to examine how anxiety and AVC contribute to the development of CUD over time.

Abstract:
As doenças cerebrovasculares são uma grande fonte de mortalidade e o Acidente Vascular Cerebral (AVC) é uma das principais causas de incapacitação no mundo. Estima-se que 80% dos AVCs primários podem ser prevenidos. É preciso, no entanto, conhecer os diversos fatores de risco associados a essa doença. Uma vez conhecidos os fatores de risco, o profissional de saúde pode adotar as medidas mais adequadas para minimizar a probabilidade de ocorrer um AVC. Este trabalho tem como objetivo realizar avaliação do preditor de risco da Rede Brasil AVC e proposição de um novo modelo. Desta forma, apresenta a experiência realizada para a modelação de um software para avaliação do risco de AVC através de um algoritmo determinístico. Com base nos resultados deste estudo, foram propostos requisitos para uma ferramenta computacional dirigida à prevenção de AVC. Um sistema preditor da avaliação do risco de AVC pode ser uma importante ferramenta de apoio na tomada da decisão compartilhada na área de saúde.

Abstract:
Introdução: A Fibrilação Atrial (FA) é considerada a arritmia cardíaca sustentada mais comum, assim como também é o fator preditivo mais importante de Acidente Vascular Cerebral isquêmico (AVC). Diversos estudos têm sugerido que curtas salvas de taquicardia atrial (TA) ou extrassístoles supraventriculares (ESSV) frequentes podem traduzir um estágio inicial de remodelamento do átrio esquerdo e seriam preditores de FA e risco aumentado de AVC. Considera-se que risco de AVC não depende do modo de apresentação da FA e alguns estudos recentes mostram que até 30% deles têm a arritmia diagnosticada antes, durante ou após o evento isquêmico inicial. De modo geral, na américa latina, o aumento da prevalência da FA tem sido associado com o envelhecimento da população geral, juntamente com um mal controle dos principais fatores de risco, incluindo a hipertensão arterial. Como resultante deste processo, a prevalência do acidente vascular cerebral (AVC) e a mortalidade associada tem aumentado dramaticamente no decorrer dos anos. Objetivo: Analisar a correlação entre fibrilação atrial como fator de predição para acidente vascular cerebral isquêmico. Métodos: Foi feita uma busca qualitativa nas plataformas Scientific Electronic Library Online (SCIELO), na Biblioteca Virtual em Saúde (BVS) e na plataforma Google Acadêmico, no intuito de buscar artigos no idioma português e inglês, bem avaliados, com os descritores acidente cerebrovascular, fibrilação atrial e prevalência, para realizar a revisão de literatura. O eixo temático é a clínica médica. Resultados: Foram selecionados 4 artigos para realização do trabalho e, a partir destes, observou-se que o AVCI pode ser definido por um déficit neurológico, geralmente focal, de instalação súbita e de rápida evolução, causada pela lesão de uma região cerebral decorrente da redução local da oferta de oxigênio, em razão do comprometimento do fluxo sanguíneo tecidual (isquemia). Dentre os fatores de risco modificáveis para o AVCI, a FA encontra-se como umas das principais, pois tem destaque como componente de gatilho tanto para o primeiro acidente quanto para episódios isquêmicos subsequentes. Observou-se também que pacientes com AVCI e com FA são, em geral, mais velhos do que aqueles sem diagnóstico de FA, e que a prevalência nas mulheres acaba sendo maior, tendo em vista que a representatividade feminina apresenta expectativa de vida superior à masculina e, por isso, podem ser mais expostas ao fator de risco idade. Ademais, verificou-se que a detecção precoce de FA tem grande importância, haja visto que o pronto início de anticoagulação pode diminuir em até 40% o risco da recorrência do AVC. Conclusão: A partir disso, pode-se perceber que os episódios de AVCI relacionados à FA podem ser considerados mais graves do que episódios não relacionados à FA devido à grande extensão do infarto associado com a oclusão de uma artéria proximal, a um maior risco de morte hospitalar e recorrência de AVC. Portanto, o AVC relacionado à FA parece ser um problema importante, uma vez que o conhecimento dos fatores de risco para AVC permite que se elaborem estratégias de prevenção primária e secundária para estes eventos vasculares.

Abstract:
Manufacturers and developers of automated vehicles (AVs) often maintain that no new infrastructure enablers are needed to achieve full AV deployment aside from existing infrastructure investments (e.g., connected traffic signals, designated stops, booking software, mobile applications, separated lanes). These groups hold that a state-of-good-repair and clean lane markings are sufficient; however, much of the US receives poor grades when it comes to these features. What do infrastructure owners and operators need to know about what constitutes effective lane markings or what to prioritize in terms of safety and mobility? How do policy considerations effect these choices? Automated Vehicles and Infrastructure Enablers the first in a series on AVs and infrastructure—considers ways in which infrastructure can speed or delay deployment, mitigate hazards, and capture benefits related to AV roll-out. Some of these benefits include accessibility, safety, reduced climate impacts, and integrated supply chain logistics.

Abstract:
This study attempts to answer the question of how a narrow (9-ft) lane dedicated to Automated Vehicles (AVs) would affect the behavior of drivers in the adjacent lane to the right. To this end, a custom driving simulator environment was designed mimicking the Interstate 15 smart corridor in San Diego. A group of participants was assigned to drive next to the simulated 9-ft narrow lane while a control group was assigned to drive next to a regular 12-ft AV lane. Driver behavior was analyzed by measuring the mean lane position, mean speed, and mental effort (self-reported/subjective measure). In addition to AV lane width, the experimental design took into consideration AV headway, gender, and right lane traffic to investigate possible interaction effects. The results showed no significant differences in the speed and mental effort of drivers while indicating significant differences in lane positioning. Although the overall effect of AV lane width was not significant, there were some significant interaction effects between lane width and other factors (i.e., driver gender and presence of traffic on the next regular lane to the right). Across all the significant interactions, there was no case in which those factors stayed constant while AV lane width changed between the groups, indicating that the significant difference stemmed from the other factors rather than the lane width. However, the trend observed was that drivers driving next to the 12-ft lane had better lane centering compared to the 9ft lane. The analysis also showed that while in general female drivers tended to drive further away from the 9-ft lane and performed worse in terms of lane centering, they performed better than male drivers when right-lane traffic was present. This study contributes to understanding the behavioral impacts of infrastructure adaptation to AVs on non-AV drivers.
