A significant set of information stored in different databases around the world, can be shared through peer-topeer databases. With that, is obtained a large base of knowledge, without the need for large investments because they are used existing databases, as well as the infrastructure in place. However, the structural characteristics of peer-topeer, makes complex the process of finding such information. On the other side, these databases are often heterogeneous in their schemas, but semantically similar in their content. A good peer-to-peer databases systems should allow the user access information from databases scattered across the network and receive only the information really relate to your topic of interest. This paper proposes to use ontologies in peer-to-peer database queries to represent the semantics inherent to the data. The main contribution of this work is enable integration between heterogeneous databases, improve the performance of such queries and use the algorithm of optimization Ant Colony to solve the problem of locating information on peer-to-peer networks, which presents an improve of 18% in results. © 2011 IEEE.

Há três teorias distintas que buscam explicar a origem da postura invertida (INV) em canhotos. O Modelo genético de McKeever postula que o traço esteja ligado ao sexo, sendo transmitido via cromossomo X, através das mães, o que explica a prevalência maior da postura INV entre o sexo masculino. De acordo com o modelo patológico a postura invertida decorre de fatores neuropatológicos, enquanto a teoria de adaptação técnica considera a postura INV como um ajuste manual para enfrentar as exigências abdutivas implícitas no sistema ortográfico romano. Muitos partidários da última teoria julgam a postura INV como prejudicial, resultando em problemas físicos e em escrita ilegível, recomendando que a mesma seja substituída pela postura não invertida (NI). Um estudo prévio foi realizado entre 96 adolescentes de classe socioeconômica (CSE) baixa, sendo 48 canhotos e 48 destros, subdivididos por sexo e postura para escrever. A presente investigação representa uma extensão deste estudo, através da avaliação de 106 alunos da CSE média, sendo 68 destros e 66 canhotos. Os objetivos principais foram averiguar se a postura invertida estava associada a problemas físicos, complicações no parto, padrões diferentes de direção grafológica, desempenho caligráfico inferior e verificar se as mesmas características variavam em função do nível da CSE. Os resultados não indicaram nenhuma relação entre postura invertida e problemas físicos e pré-natais no estímulo grafológico. Os canhotos com postura INV mais do que os canhotos NI e destros tenderam a desenhar as linhas horizontais na direção direita para esquerda; nas outras tarefas de desenhos grafológicos não diferiram dos outros grupos. Nas tarefas cursivas e letras de forma o desempenho das alunas foi consistentemente superior ao dos alunos de modo geral. Os canhotos emitiram mais erros quando escreveram em letras de forma, mas não na escrita cursiva. O tempo de resposta foi à única variável dependente relacionada a CSE: alunos da CSE média escreveram as frases em letras cursivas e letras de forma mais rapidamente do que os alunos da CSE baixa. De modo geral, esses resultados não apóiam a afirmação de que a postura invertida acarreta problemas físicos, desempenho caligráfico inferior e não justifica a prática pedagógica em desencorajar o uso da postura INV.

This study aimed to verify the effects of a metatextual intervention program, in the elaboration of stories written by students with learning difficulties. Four students were included in the sample of both genders, with ages ranging between eight years and four months and ten years and two months of age. The program was implemented at the participant schools, using an approach of multiple baseline within-subjects, with two conditions: baseline and intervention. Data analysis was based on the classification of stories produced by the students. Mann-Whitney testing was also applied, to analyze whether there have been significant changes in these productions. The results indicated that all students have improved performance in relation to the categories of produced stories, from elementary schemas (33%), for a more elaborate scheme (77%), with a better structuring of the elements that constitute a story. Statistical analysis also showed that the intervention has produced significant results for all variables analyzed. The data obtained have shown that the program was effective.

Periodontitis is a chronic inflammatory disease that results in the destruction of teeth and their supporting tissues with subsequent tooth loss. The replacement of missing teeth for implant-supported restorations has proven to be a highly predictable treatment method with good long-term prognosis. However, some consequences of tooth loss prevents dental implant placement in an ideal position, where regenerative procedures are necessary for this type of rehabilitation. Less invasive procedures such as conventional prosthesis emerge as a therapeutic option in cases where there is enough bone structure for implants and patient´s non-acceptance for invasive procedures. Thus, this paper aims to present the resolution of rehabilitation through a noninvasive and multidisciplinary treatment. One female patient referred to the clinic presented maladaptive bilateral mandibular fixed prostheses, endodontic lesions, gingival recession, and root sensitivity. For proper resolution of this case, an association among osseointegrated implants, fixed partial prosthesis, tooth extraction, and aesthetic periodontal procedures with the use of subepithelial connective tissue graft was proposed. After two years, the patient shows excellent aesthetics and chewing. Within the limits of this scenario, this paper discusses the various factors that may affect the choice of a particular treatment modality for the rehabilitation of edentulous single spaces.

Objective: Obesity and renin angiotensin system (RAS) hyperactivity are profoundly involved in cardiovascular diseases, however aerobic exercise training (EXT) can prevent obesity and cardiac RAS activation. The study hypothesis was to investigate whether obesity and its association with EXT alter the systemic and cardiac RAS components in an obese Zucker rat strain. Methods: The rats were divided into the following groups: Lean Zucker rats (LZR); lean Zucker rats plus EXT (LZR+EXT); obese Zucker rats (OZR) and obese Zucker rats plus EXT (OZR+EXT). EXT consisted of 10 weeks of 60-min swimming sessions, 5 days/week. At the end of the training protocol heart rate (HR), systolic blood pressure (SBP), cardiac hypertrophy (CH) and function, local and systemic components of RAS were evaluated. Also, systemic glucose, triglycerides, total cholesterol and its LDL and HDL fractions were measured. Results: The resting HR decreased (, 12%) for both LZR+EXT and OZR+EXT. However, only the LZR+EXT reached significance (p, 0.05), while a tendency was found for OZR versus OZR+EXT (p = 0.07). In addition, exercise reduced (57%) triglycerides and (61%) LDL in the OZR+EXT. The systemic angiotensin I-converting enzyme (ACE) activity did not differ regardless of obesity and EXT, however, the OZR and OZR+EXT showed (66%) and (42%), respectively, less angiotensin II (Ang II) plasma concentration when compared with LZR. Furthermore, the results showed that EXT in the OZR prevented increase in CH, cardiac ACE activity, Ang II and AT2 receptor caused by obesity. In addition, exercise augmented cardiac ACE2 in both training groups. Conclusion: Despite the unchanged ACE and lower systemic Ang II levels in obesity, the cardiac RAS was increased in OZR and EXT in obese Zucker rats reduced some of the cardiac RAS components and prevented obesity-related CH. These results show that EXT prevented the heart RAS hyperactivity and cardiac maladaptive morphological alterations in obese Zucker rats.
