Funcionalidade e qualidade de vida : um estudo no processo de envelhecimento em portadores e não portadores da diabetes tipo 2

RESUMO: Introdução: A diabetes é uma patologia crônica que vêm crescendo exponencialmente em países desenvolvidos e, principalmente, naqueles em desenvolvimento, como é o caso do Brasil. Além de gerar importante custo aos sistemas públicos de saúde, sabe-se que as consequências do mau controle da diabetes tem impacto importante na vida de indivíduos que apresentam a doença, como a perda precoce da funcionalidade e a reduzida qualidade de vida. Nesse sentido, o governo federal brasileiro estabelece em 2002 o Programa Hiperdia, que prevê educação terapêutica e a assistência multiprofissional como estratégias na prevenção e controle das consequências geradas pelo mau controle da diabetes. Objetivo: O estudo aqui proposto tem como objetivo avaliar de que modo a presença e o tempo de diagnóstico da diabetes do tipo 2 (DM2) estão associados à funcionalidade e qualidade de vida de indivíduos assistidos pelo Programa Hiperdia. Metodologia: Foram avaliados indivíduos com idade igual ou superior a 40 anos, residentes na cidade de Viçosa-Minas Gerais/Brasil, distribuídos em diferentes grupos conforme as perspectivas de análise 1 (estudo da presença da DM2) e 2 (estudo do tempo de diagnóstico da patologia). Para a perspectiva 1 dois diferentes grupos foram comparados: controle (CTL), indivíduos sem DM2 ou qualquer patologia em órgãos alvo da doença; e DM2, indivíduos diagnosticados com diabetes do tipo 2. Já para a perspectiva 2 de análise pessoas diagnosticadas com DM2 foram distribuídas em dois diferentes grupos: G1, indivíduos com tempo de diagnóstico da DM2 ≥ 1 ano e ≤ 5 anos; e G2, indivíduos com tempo de diagnóstico da DM2 ≥ 10 anos. Previamente, avaliamos o estado cognitivo dos participantes por meio do Mini Mental State Exam. Dados sociodemográficos e clínicos (rastreio de sintomas depressivos, sonolência diurna excessiva e antropometria) também foram avaliados, além da verificação do perfil bioquímico por meio de informações provenientes de prontuários médicos. Para o estudo da funcionalidade, os instrumentos Activities of Daily Living, Instrumental Activities of Daily Living e o Life Style Questionnaire foram utilizados, assim como o SF-36v2 para a avaliação da qualidade de vida. Por fim, outras variáveis como conhecimento sobre a DM2 e gestão da patologia também foram investigadas. 10 Resultados: 198 indivíduos (CTL: 81; DM2: 117) com idade ≥ 40 anos foram avaliados, dos quais 55,5% apresentaram idade igual ou superior a 60 anos. A maioria corresponderam ao sexo feminino (62,6%). Foram verificados similares resultados para o estado cognitivo em ambas as perspectivas de análise. Pode-se dizer que, para a perspectiva 1 (CTL vs. DM2), os grupos apresentaram diferenças estatísticas significantes para a maioria das variáveis estudadas e tendência para a variável estilo de vida, com resultados desfavorecedores ao grupo DM2. Para a perspectiva 2 (G1 vs. G2), nossos resultados não evidenciam diferenças significantes para o tempo de diagnóstico em nenhuma das variáveis estudadas. Conclusões: Os resultados do estudo mostram que a presença da DM2 em situação de inadequado controle, bem como o insuficiente conhecimento sobre a patologia entre os indivíduos assistidos pelo Centro Hiperdia podem representar um importante fator para a verificação da reduzida funcionalidade e qualidade de vida. Isto sugere a necessidade de ajustes na execução do Programa, de modo a tornar possível o alcance dos objetivos propostos pelo mesmo. Referente ao tempo de diagnóstico da DM2, em nossa amostra, os resultados indicam que este parece não representar um fator desfavorecedor da funcionalidade e qualidade de vida.---------------------------ABSTRACT: Introduction: Type 2 diabetes (DM2) is a chronic disease that has been growing exponentially in developed countries, and even more so in developing countries such as Brazil. In addition, the pathology generates a significant cost to public healthcare systems. It is well known that the poor control of diabetes has important consequences on the lives of individuals diagnosed with the disease, such as the early loss of functionality and a reduced quality of life. In this sense, the Brazilian federal government established the Programa Hiperdia in 2002, a program that provides therapeutic education and multidisciplinary care in order to prevent and control the consequences of diabetes. Objective: The aim of this study is to evaluate how the presence and the diagnosis time of DM2 are associated with the functionality and quality of life of individuals assisted by the Programa Hiperdia. Methodology: We evaluated individuals aged 40 years or older living in Viçosa, Minas Gerais/Brazil, and divided them into different groups according to the analytical perspectives 1 (the study of the presence of DM2) and 2 (the study of the diagnosis time of DM2). For perspective 1, two different groups were compared: the DM2 group, which consisted of individuals diagnosed with type 2 diabetes, and the control group (CTL), which consisted of individuals without type 2 diabetes or any disease in the target organs. For perspective 2, people diagnosed with type 2 diabetes were divided into two different groups: G1, individuals with diagnosis time ≥ 1 year and ≤ 5 years; and G2, individuals with diagnosis time ≥ 10 years. Prior to group assignment, we assessed the cognitive status of all participants with the Mini Mental State Exam (MMSE). Sociodemographic and clinical data (i.e. screening of depressive symptoms, excessive daytime sleepiness and anthropometry) were also evaluated, as well as the biochemical profile based on information from the local Hiperdia center. To study functionality, Activities of Daily Living, Instrumental Activities of Daily Living and Life Style Questionnaire were administered. Quality of life was assessed via the SF-36v2 Health Survey. Finally, variables such as knowledge about DM2 and disease management were also verified. Results: 198 subjects (CTL: 81; DM2: 117) aged ≥ 40 years were evaluated, of whom 55.5% were aged 60 years or older. The majority of subjects were women (62,6%). Cognitive status scores were similar amongst both analytical perspectives. In terms of perspective 1 (DM2. vs. CTL), it showed statistically significant differences between the groups for the most part of the variables studied, and poorer results in the DM2 group. Regarding perspective 2 (G1 vs. G2), our results did not show significant differences for the diagnosis time in any of the variables studied. Conclusions: Our findings show that the presence of DM2 with inadequate control of the condition, as well as lack of knowledge about the disease among individuals assisted by the Hiperdia center may represent an important factor in the poor functionality and reduced quality of life when compared to the control group. This suggests that the Program likely needs some adjustments on its implementation in order to make possible the achievement of the objectives proposed. With respect to the diagnosis time for DM2 in our sample, the results indicate that it does not seem to be a factor in poor functionality nor quality of life.

Peer interaction and learning opportunities in cohesive and less cohesive L2 classrooms

The present study investigates peer to peer oral interaction in two task based language teaching classrooms, one of which was a self-declared cohesive group, and the other a self- declared less cohesive group, both at B1 level. It studies how learners talk cohesion into being and considers how this talk leads to learning opportunities in these groups. The study was classroom-based and was carried out over the period of an academic year. Research was conducted in the classrooms and the tasks were part of regular class work. The research was framed within a sociocognitive perspective of second language learning and data came from a number of sources, namely questionnaires, interviews and audio recorded talk of dyads, triads and groups of four students completing a total of eight oral tasks. These audio recordings were transcribed and analysed qualitatively for interactions which encouraged a positive social dimension and behaviours which led to learning opportunities, using conversation analysis. In addition, recordings were analysed quantitatively for learning opportunities and quantity and quality of language produced. Results show that learners in both classes exhibited multiple behaviours in interaction which could promote a positive social dimension, although behaviours which could discourage positive affect amongst group members were also found. Analysis of interactions also revealed the many ways in which learners in both the cohesive and less cohesive class created learning opportunities. Further qualitative analysis of these interactions showed that a number of factors including how learners approach a task, the decisions they make at zones of interactional transition and the affective relationship between participants influence the amount of learning opportunities created, as well as the quality and quantity of language produced. The main conclusion of the study is that it is not the cohesive nature of the group as a whole but the nature of the relationship between the individual members of the small group completing the task which influences the effectiveness of oral interaction for learning.This study contributes to our understanding of the way in which learners individualise the learning space and highlights the situated nature of language learning. It shows how individuals interact with each other and the task, and how talk in interaction changes moment-by-moment as learners react to the ‘here and now’ of the classroom environment.

Role of Intersectoral Collaboration in Mental Health Policy Formulation And Service Delivery in Saint Lucia

RESUMO: Santa Lúcia pequena ilha de país em desenvolvimento com recursos limitados e é confrontada com uma série de desafios socioeconômicos que exigem soluções criativas e inovadoras. É comprovado que a combinação de recursos entre setores para estabelecer os determinantes social, econômico e ambiental da saúde são uma estratégia útil para melhorar a saúde da população, principalmente a sua saúde mental. Este estudo, o primeiro do seu tipo em Santa Lúcia, procurou examinar até que ponto a disponibilidade de uma política nacional de saúde mental levou a ação intersetorial para o fornecimento de serviços e promoção da saúde mental. Além disso, o estudo examinou o nível de colaboração intersetorial que existe entre as agências que prestam cuidados diretos e serviços de suporte para pessoas com doenças mentais e problemas sérios de saúde mental. O estudo também teve como objetivo identificar os fatores que promovem ou dificultam a colaboração intersectorial e gerar recomendações que possam ser aplicadas para países muito pequenos e com perfis socioeconômicos semelhantes. Os dados gerados a partir de três (3) fontes foram sintetizados para formar uma visão ampla das questões. Uma avaliação da política de saúde mental de 2007, uma avaliação que identifica até que ponto a ação intersetorial atualmente deixa a prestação de serviços de saúde mental e a administração de entrevistas semiestruturadas nas mãos de gestores do programa de diferentes agências em todos os setores. O estudo concluiu que, apesar da disponibilidade de uma política de saúde mental, que articula clara e explicitamente a colaboração intersetorial como área prioritária para ação, quase não existe no sistema de fornecimento atual do serviço. Os provedores de serviços em todos os setores reconhecem que há os benefícios da colaboração intersectorial e com entraves significativos em relação à colaboração intersetorial, que por sua vez, impede uma abordagem nacional para o planejamento e o fornecimento do serviço. A colaboração intersetorial não será possível se os próprios setores dependerem da abordagem direta do setor da saúde ou se a atmosfera geral for ofuscada pela estigmatização das doenças mentais.------------------------------------------------------------------------ABSTRACT: Saint Lucia a small island developing country with limited resources, is faced with a number of socio-economic challenges which require creative and innovative solutions to address. Combining resources across sectors to address the social, economic and environmental determinants of health has proven to be a useful strategy for improving population health in particular mental health. This study, the first of its kind for Saint Lucia sought to examine the extent to which the availability of a national mental health policy led to intersectoral action for mental health promotion and service delivery. In addition the study examined the level of intersectoral collaboration which actually exist between agencies which provide direct care and support services to people with mental illnesses and significant mental health problems. The study also aimed to identify the factors which promote or hinder intersectoral collaboration and generate recommendations which can be applied to extremely small countries with similar socio-economic profiles. Data generated from three (3) sources was synthesized to form a broad picture of the issues. An evaluation of the mental health policy of 2007, an assessment of the extent to which intersectoral action currently exist in mental health service delivery and the administration of semi-structured interviews with program managers from different agencies across sectors to identify implementation issues. The study concluded that despite the availability of a mental health policy which clearly and explicitly articulates intersectoral collaboration as a priority area for action, very little exists in the current service delivery system. Services providers across sectors acknowledge the benefits of intersectoral collaboration and that there are significant barriers to intersectoral collaboration, which in turn hinders a national approach to service planning and delivery. Intersectoral collaboration is not possible if sectors themselves are dependent on a top-down health sector driven and dominated approach, or if the general atmosphere is clouded by stigmatization of mental health illnesses.

Community indentification in peer-t-peer collaborative consumption services

Even though collaborative consumption (CC) is gaining economic importance, research in CC is still in its infancy. Consumers’ reasons for participating have already been investigated but little research on consequences of participation has been conducted. This article examines whether interactions between customers in peer-to-peer CC services influence the willingness to coproduce service outcomes. Drawing on social exchange theory, it is proposed that this effect is mediated by consumers’ identification with the brand community. Furthermore, continuance intention in CC is introduced as a second stage moderator. In a cross-sectional study, customers of peer-to-peer accommodation sharing are surveyed. While customer-to-customer interactions were found to have a positive effect on brand community identification, brand community identification did not positively affect co-production intention. Surprisingly, the effect of brand community identification on co-production intention was negative. Moreover, continuance intention of customers did not moderate this relationship. Bearing in mind current challenges for researchers and companies, theoretical and managerial implications are discussed.

Implementation of a probabilistic based framework for safety assessment of existing timber elements

The assessment of existing timber structures is often limited to information obtained from non or semi destructive testing, as mechanical testing is in many cases not possible due to its destructive nature. Therefore, the available data provides only an indirect measurement of the reference mechanical properties of timber elements, often obtained through empirical based correlations. Moreover, the data must result from the combination of different tests, as to provide a reliable source of information for a structural analysis. Even if general guidelines are available for each typology of testing, there is still a need for a global methodology allowing to combine information from different sources and infer upon that information in a decision process. In this scope, the present work presents the implementation of a probabilistic based framework for safety assessment of existing timber elements. This methodology combines information gathered in different scales and follows a probabilistic framework allowing for the structural assessment of existing timber elements with possibility of inference and updating of its mechanical properties, through Bayesian methods. The probabilistic based framework is based in four main steps: (i) scale of information; (ii) measurement data; (iii) probability assignment; and (iv) structural analysis. In this work, the proposed methodology is implemented in a case study. Data was obtained through a multi-scale experimental campaign made to old chestnut timber beams accounting correlations of non and semi-destructive tests with mechanical properties. Finally, different inference scenarios are discussed aiming at the characterization of the safety level of the elements.

The tutor's role in student learning

Higher education in Portugal, in the last forty years, has undergone profound changes with the enlargement of public higher education network, the appearance of new institutions, the quantity and the heterogeneity of students. The implementation of the Bologna Process in European community countries led to the redesign of higher education Portuguese courses as well as their corresponding curricula. In recent years, the use of Project-led education was one of the most significant changes in teaching and learning, particularly in engineering in higher education in Portugal. This teaching methodology encourages students and teachers to undertake new roles, new responsibilities and a new learning perspective. This study aims at understanding whether the role of the tutor is to be suitable to the needs and expectations of Project-led education students. These changes however are not only structural. At the University of Minho, new teaching and learning methodologies were adopted, which could guide the training of professionals on to the twenty-first century. The opportunity arising from the implementation of Project-led education in Engineering methodology was used in the University of Minho’s courses. This teaching method is intended to provide students with educational support programs that benefit the academic performance, allowing the opportunity to upgrade, train and develop the ability to study and learn more effectively. Through the Project-led education it is possible to provide students with techniques and procedures and develop the ability to communicate orally and in writing. Students and teachers have assumed new roles in the teaching-learning process allowing in one hand the students to explore, discover and question themselves about some knowledge and on the other hand the teachers to change to a tutor, a companion and to a student project guide. Therefore, surveys were analyzed, comprising questions about the most significant contribution of the tutor as well as if there are some initial expectations that have not been foreseen by the tutor.

Conceptual-physical bridging – From BPMN models to physical implementations on kettle

Developing and implementing data-oriented workflows for data migration processes are complex tasks involving several problems related to the integration of data coming from different schemas. Usually, they involve very specific requirements - every process is almost unique. Having a way to abstract their representation will help us to better understand and validate them with business users, which is a crucial step for requirements validation. In this demo we present an approach that provides a way to enrich incrementally conceptual models in order to support an automatic way for producing their correspondent physical implementation. In this demo we will show how B2K (Business to Kettle) system works transforming BPMN 2.0 conceptual models into Kettle data-integration executable processes, approaching the most relevant aspects related to model design and enrichment, model to system transformation, and system execution.

Using a domain-specific language to enrich ETL schemas

Today it is easy to find a lot of tools to define data migration schemas among different types of information systems. Data migration processes use to be implemented on a very diverse range of applications, ranging from conventional operational systems to data warehousing platforms. The implementation of a data migration process often involves a serious planning, considering the development of conceptual migration schemas at early stages. Such schemas help architects and engineers to plan and discuss the most adequate way to migrate data between two different systems. In this paper we present and discuss a way for enriching data migration conceptual schemas in BPMN using a domain-specific language, demonstrating how to convert such enriched schemas to a first correspondent physical representation (a skeleton) in a conventional ETL implementation tool like Kettle.

Automatic generation of ETL physical systems from BPMN conceptual models

ETL conceptual modeling is a very important activity in any data warehousing system project implementation. Owning a high-level system representation allowing for a clear identification of the main parts of a data warehousing system is clearly a great advantage, especially in early stages of design and development. However, the effort to model conceptually an ETL system rarely is properly rewarded. Translating ETL conceptual models directly into something that saves work and time on the concrete implementation of the system process it would be, in fact, a great help. In this paper we present and discuss a hybrid approach to this problem, combining the simplicity of interpretation and power of expression of BPMN on ETL systems conceptualization with the use of ETL patterns to produce automatically an ETL skeleton, a first prototype system, which has the ability to be executed in a commercial ETL tool like Kettle.

Implementation of a lean six sigma project in a production line

Companies from the motorcycles components branch are dealing with a dynamic environment, resulting from the introduction of new products and the increase of market demand. This dynamic environment requires frequent changes in production lines and requires flexibility in the processes, which can cause reductions in the level of quality and productivity. This paper presents a Lean Six Sigma improvement project performed in a production line of the company's machining sector, in order to eliminate losses that cause low productivity, affecting the fulfillment of the production plan and customer satisfaction. The use of Lean methodology following the DMAIC stages allowed analyzing the factors that influence the line productivity loss. The major problems and causes that contribute to a reduction on productivity and that were identified in this study are the lack of standardization in the setup activities and the excessive stoppages for adjustment of the processes that caused an increase of defects. Control charts, Pareto analysis and cause-and-effect diagrams were used to analyze the problem. On the improvement stage, the changes were based on the reconfiguration of the line layout as well as the modernization of the process. Overall, the project justified an investment in new equipment, the defective product units were reduced by 84% and an increase of 29% of line capacity was noticed.

Implementation and comparison of different switching techniques for shunt active power filters

This paper presents a comparison between three switching techniques that can be used in three-phase four-wire Shunt Active Power Filters (SAPFs). The implemented switching techniques are: Periodic-Sampling (PS), Triangular Carrier Pulse-Width Modulation (TC-PWM) and Space Vector PWM (SVPWM). The comparison between them is made in terms of the compensated currents THD%, implementation complexity, necessary CPU time and SAPF efficiency. To perform this comparison are presented and analyzed several experimental results, obtained with a 20 kVA Shunt Active Power Filter prototype, specially developed for this purpose. The control system of the developed SAPF is based in the p-q Theory with a grid synchronization algorithm p-PLL.
