National Immunization Program: Computerized System as a tool for new challenges

The scope and coverage of the Brazilian Immunization Program can be compared with those in developed countries because it provides a large number of vaccines and has a considerable coverage. The increasing complexity of the program brings challenges regarding its development, high coverage levels, access equality, and safety. The Immunization Information System, with nominal data, is an innovative tool that can more accurately monitor these indicators and allows the evaluation of the impact of new vaccination strategies. The main difficulties for such a system are in its implementation process, training of professionals, mastering its use, its constant maintenance needs and ensuring the information contained remain confidential. Therefore, encouraging the development of this tool should be part of public health policies and should also be involved in the three spheres of government as well as the public and private vaccination services.

Use of the Brazilian People’s Pharmacy Program by older adults

ABSTRACT OBJECTIVE To assess the prevalence and factors associated with the use of the expanded Brazilian People’s Pharmacy Program among older adults and the reasons for not using it. METHODS In this population-based cross-sectional study conducted in the urban area of Pelotas, RS, Southern Brazil, we evaluated 1,305 older adults (aged 60 years or over) who had used medication in the last 15 days. Independent variables were socioeconomic factors, economic status, household income in minimum wages, educational attainment in years of schooling and occupational status. Demographic variables were sex, age, marital status, and self-reported skin color/race. Poisson regression was employed to analyze the factors associated with the use of the program. RESULTS The prevalence of use was 57.0% whilst the prevalence of knowledge of the program was 87.0%. In individuals aged 80 years or over, use of the program was 41.0%. As to the origin of the prescriptions used by older adults, 46.0% were from the Brazilian Unified Health System. The main reasons for not using the program were: difficulty in getting prescriptions, medication shortage, and ignorance about the medications offered and about the program. Higher age, lower income, presence of chronic diseases, and use of four or more medications were associated with use of the program. CONCLUSIONS It is necessary to expand the knowledge and use of the Brazilian People’s Pharmacy Program, especially among older adults, and to improve the dissemination of its list of medications to users and physicians. Thus it will be possible to reduce spending on long-term medications, which are especially important for this population.

A contribution to the e-framework: a specification of a programming exercise evaluation service

This work is a contribution to the e-Framework, arguably the most prominent e-learning framework today, and consists of the definition of a service for the automatic evaluation of programming exercises. This evaluation domain differs from trivial evaluations modelled by languages such as the IMS Question & Test Interoperability (QTI) specification. Complex evaluation domains justify the development of specialized evaluators that participate in several business processes. These business processes can combine other type of systems such as Programming Contest Management Systems, Learning Management Systems, Integrated Development Environments and Learning Object Repositories where programming exercises are stored as Learning Objects. This contribution describes the implementation approaches used, more precisely, behaviours & requests, use & interactions, applicable standards, interface definition and usage scenarios.

Modelling an e-learning environment for learning programming languages

It is widely accepted that solving programming exercises is fundamental to learn how to program. Nevertheless, solving exercises is only effective if students receive an assessment on their work. An exercise solved wrong will consolidate a false belief, and without feedback many students will not be able to overcome their difficulties. However, creating, managing and accessing a large number of exercises, covering all the points in the curricula of a programming course, in classes with large number of students, can be a daunting task without the appropriated tools working in unison. This involves a diversity of tools, from the environments where programs are coded, to automatic program evaluators providing feedback on the attempts of students, passing through the authoring, management and sequencing of programming exercises as learning objects. We believe that the integration of these tools will have a great impact in acquiring programming skills. Our research objective is to manage and coordinate a network of eLearning systems where students can solve computer programming exercises. Networks of this kind include systems such as learning management systems (LMS), evaluation engines (EE), learning objects repositories (LOR) and exercise resolution environments (ERE). Our strategy to achieve the interoperability among these tools is based on a shared definition of programming exercise as a Learning Object (LO).

Testes de endurance do tronco: diferenças entre indivíduos com e sem dor lombo-pélvica e o efeito de programas de exercício de controlo motor

Introdução: em indivíduos com dor lombo-pélvica (LPP), parece existir uma alteração de controlo motor e diminuição da endurance dos músculos do tronco. A realização de exercícios de controlo motor pode melhorar a endurance dessa musculatura e consequentemente o controlo motor. Objetivos: detetar diferenças nos tempos e rácios de endurance dos músculos do tronco em indivíduos com e sem dor lombo-pélvica e avaliar o efeito de dois programas de exercícios de controlo motor (segundo Richardson e segundo McGill) nos mesmos outcomes em indivíduos com LPP. Métodos: estudo transversal com uma amostra de 111 indivíduos, 52 para o grupo sem dor (NLPP) e 59 para o com LPP e estudo experimental, constituído pelos indivíduos LPP (59), alocados nos grupos de Pilates (20), McGill (20) ou no grupo controlo (19). Avaliaramse os tempos obtidos nos testes de endurance para os músculos extensores, flexores, flexores laterais direitos e esquerdos do tronco e respetivos rácios, tendo em conta o modelo de McGill. As avaliações dos grupos do estudo experimental realizaram-se antes e após as 8 semanas de exercício. Resultados: os indivíduos com LPP apresentaram tempos e rácios de endurance significativamente inferiores aos indivíduos NLPP (p<0.001). Após as 8 semanas de exercício, registaram-se diferenças estatisticamente significativas entre os grupos em todos os testes de endurance, sendo que o grupo de McGill apresentou tempos significativamente superiores aos do grupo de Pilates para os músculos flexores (p=0.001), flexores laterais direitos (p=0.002) e esquerdos (p=0.009). Quanto aos rácios de endurance, não se detetaram apenas diferenças estatisticamente significativas no rácio flexão lateral esquerda/extensão. Conclusão: os indivíduos com LPP apresentaram tempos e rácios de endurance do tronco inferiores aos dos indivíduos sem dor. Ambos os programas de exercícios melhoraram os tempos e os rácios de endurance, tendo existido uma tendência para melhores resultados na abordagem segundo McGill

CodeSkelGen: a program skeleton generator

Existent computer programming training environments help users to learn programming by solving problems from scratch. Nevertheless, initiating the resolution of a program can be frustrating and demotivating if the student does not know where and how to start. Skeleton programming facilitates a top-down design approach, where a partially functional system with complete high level structures is available, so the student needs only to progressively complete or update the code to meet the requirements of the problem. This paper presents CodeSkelGen - a program skeleton generator. CodeSkelGen generates skeleton or buggy Java programs from a complete annotated program solution provided by the teacher. The annotations are formally described within an annotation type and processed by an annotation processor. This processor is responsible for a set of actions ranging from the creation of dummy methods to the exchange of operator types included in the source code. The generator tool will be included in a learning environment that aims to assist teachers in the creation of programming exercises and to help students in their resolution.

Lean and quality management integration: improvement program implementation in a service company

Lean Thinking is an important pillar in the success of any program of continuous improvement process. Its tools are useful means in the analysis, control and organization of important data for correct decision making in organizations. This project had as main objective the design of a program of quality improvement in Eurico Ferreira, S.A., based on the evaluation of customer satisfaction and the implementation of 5S. Subsequently, we have selected which business area of the company to address. After the selection, there was an initial diagnostic procedure, identifying the various points of improvement to which some tools of Lean Thinking have been applied, in particular Value Stream Mapping and 5S methodology. With the first, we were able to map the current state of the process in which all stakeholders were represented as well as the flow of materials and information throughout the process. The 5S methodology allowed to act on the wastage, identifying and implementing various process improvements.

China's space program : a new tool for PRC "soft power" in international relations?

When China launched an anti-satellite (ASAT) weapon in January 2007 to destroy one of its inactive weather satellites, most reactions from academics and U.S. space experts focused on a potential military “space race” between the United States and China. Overlooked, however, is China’s growing role as global competitor on the non-military side of space. China’s space program goes far beyond military counterspace applications and manifests manned space aspirations, including lunar exploration. Its pursuit of both commercial and scientific international space ventures constitutes a small, yet growing, percentage of the global space launch and related satellite service industry. It also highlights China’s willingness to cooperate with nations far away from Asia for political and strategic purposes. These partnerships may constitute a challenge to the United States and enhance China’s “soft power” among key American allies and even in some regions traditionally dominated by U.S. influence (e.g., Latin America and Africa). Thus, an appropriate U.S. response may not lie in a “hard power” counterspace effort but instead in a revival of U.S. space outreach of the past, as well as implementation of more business-friendly export control policies.

Metedologia de avaliação da ingestão nutricional e comportamentos alimentares associados num programa de tratamento de obesidade

Resumo: últimas décadas, sendo já considerada uma doença crónica. Ao longo dos anos, ainvestigação desenvolvida nessa área permitiu definir com maior rigor a sua forma de avaliação. Relativamente à avaliação do processo de ingestão alimentar no tratamento da obesidade, e com o objectivo de se obter uma perspectiva completa e contínua, não será suficiente avaliar apenas variáveis nutricionais, mas devem também constar variáveis relacionadas com o comportamento alimentar. O presente trabalho irá enquadrar as áreas fundamentais a avaliar nas componentes da ingestão nutricional e dos comportamentos alimentares associados, e, mais especificamente, apreciar a metodologia de avaliação usada nesse domínio, num programa de tratamento comportamental da obesidade, randomizado e controlado ‐ o programa PESO (Promoção do Exercício e Saúde na Obesidade). Embora este Programa não tenha sido especificamente concebido para avaliar as componentes acima referidas como variáveis‐alvo principais, os dados são relevantes para avaliar o impacte do Programa. Os principais resultados sugerem melhorias evidentes nas variáveis críticas na gestão do peso, tanto na componente da ingestão nutricional como no comportamento alimentar.-----------ABSTRACT: The prevalence of obesity has increased significantly in the last decades and is now considered a chronic disease. Over the years, the research undertaken in this area allowed to define more rigorous ways to assess it. To evaluate dietary intake process in the treatment of obesity, and to achieve a more complete and continuous measurement, it’s not enough to assess the nutritional variables, it’s also necessary to include eating behavior related variables. This work will focus in key areas to evaluate nutritional intake and eating behavior variables, and also in the methodology assessment used in this domain, in a behavioral treatment program of obesity, a randomized controlled trial, named PESO (Promotion of Exercise and Health in Obesity). Although this program was not specifically designed to assess the above components as variables main target, the data are relevant to assess the Program impact. The main results suggest an obvious improvement in weight management critical variables, both in nutritional intake component and eating behavior.
