El proceso de investigación que se propuso en este documento aportó una descripción del impacto que tiene el uso de herramientas digitales que han logrado envolver al estudiante y a su vez, permitió establecer si además de elevar los niveles motivacionales pudo influir en el desarrollo de habilidades relacionadas con procesos de comprensión lectora. Por ello, el objetivo general plantea: “Describir el impacto del uso de las TIC en los niveles de comprensión lectora en estudiantes del grado 5°JM del Colegio Nicolás Gómez Dávila”. Para ello, fue necesario ahondar en las siguientes categorías de análisis: Comprensión Lectora, Herramientas TIC y Acompañamiento familiar en procesos de comprensión lectora. El enfoque de la investigación fue de carácter cualitativo y el diseño de la investigación estuvo bajo las premisas de la investigación – acción. Para dar cuenta del objetivo de la investigación se aplicaron los siguientes instrumentos validados por un experto: una encuesta a los padres de familia, tres pruebas de entrada y tres pruebas de salida de comprensión lectora a 15 estudiantes del grado 5°JM. Esto permitió generar algunas recomendaciones dirigidas al fortalecimiento de la compresión lectora mediada por las TIC.

The recent implementation of the General Data Protection Regulation (GDPR) establishes a set of formal requirements that reinforce personal data protection, namely, those concerning the collection, treatment, and dissemination of data on research participants. With the application of this new legal provision at the European level, new types of restrictions are emerging, whose nature and reach intensify the tension between demands for privacy and scientific freedom in research. In this article, we take as a reference an ongoing research taking place in Portugal, in the field of Sociology of Health, concerning the consumption of medicines by professionals exposed to high-performance pressure. Our main objective is to identify and analyse the implications of regulatory challenges faced in the research process and how the researchers managed and overcame them. We present a critical narrative that sheds light on the nature of the choices taken while also assessing the practical implications for the operationalisation of the research. We conclude by noting that, despite the benefits that may flow from the application of GDPR, the new requirements regarding the protection of personal data may override the ethical principles of scientific research and strengthen regulatory restrictions on conducting research. In the research concerned, the significant practical implications were indirect access to participants, a more time-consuming process in terms of participant adherence and a temporal discrepancy between the different stages of recruitment.

Background People with COPD have been reported to bear a distinct airway microbiota from healthy individuals based on bronchoalveolar lavage (BAL) and sputum samples. Unfortunately, the collection of these samples involves relatively invasive procedures and is resource-demanding, limiting its regular use. Non-invasive samples from the upper airways could constitute an interesting alternative, but its relationship with COPD is still underexplored. We examined the merits of saliva to identify the typical profile of COPD oral bacteria and test its association with the disease. Methods Outpatients with COPD and age-sex matched healthy controls were recruited and characterised based on clinical parameters and 16S rRNA profiling of oral bacteria. A clustering analysis based on patients’ oral bacteria beta-diversity and logistic regressions were performed to evaluate the association between oral bacteria composition and COPD. Results 128 individuals participated (70 patients and 58 controls). Differential abundance analyses showed differences in patients comparable to the ones previously observed in samples from the lower respiratory tract, i.e., an increase in Proteobacteria (particularly Haemophilus) and loss of microbiota diversity. An unsupervised clustering analysis separated patients in two groups based on microbiota composition differing significantly in the frequency of patients hospitalized due to severe acute exacerbation of COPD (AECOPD) and in the frequency of GOLD D patients. Furthermore, a low frequency of Prevotella was associated with a significantly higher risk of recent severe AECOPD and of being GOLD D. Conclusion Salivary bacteria showed an association with COPD, particularly with severe exacerbations, supporting the use of this non-invasive specimen for future studies of heterogeneous respiratory diseases like COPD.

Pensar em fluxos e deslocamentos de um devir crianceiro. Quais são os novos territórios capazes de serem compostos em oficinas realizadas com migrantes e refugiados, adolescentes alunos de escolas públicas e crianças? Que imagens brotam como potências de tais encontros? Este artigo organiza-se em três diferentes extratos a partir dos quais as representações de crianças migrantes e refugiadas compõem planos de pensamento e experimentação entre palavras e imagens. Apostando em algumas disjunções entre imagem e representação, consideraremos que esses planos, tais quais o objeto mundo ou qualquer objeto que seja capturado e transformado em imagem, poderá se subjetivar. À diferença do visual, que remete a figura a si mesma, as imagens criam remissões a uma outra coisa, trabalhando significados que supõem a relação entre todo e partes, as expectativas de preenchimento e as relações entre visibilidade e os seus significados. Os resultados das oficinas oferecem perspectivas de distintos modos de as imagens habitarem e instaurarem mundos outros.

Loneliness is a subjective experience escalating worldwide and affecting older adults. Digital solutions can play a major role in addressing loneliness, although its use has been facing resistance due to scarce involvement of older adults in its design. MOAI LABS is an ongoing European project that adopts a co-design process to develop digital solutions to address loneliness in older adults. This study reports the experience of loneliness shared by a group of eight community-dwelling older Portuguese adults (aged 64 to 86 years old), who are "experts by experience" (who feel alone). Findings were obtained from two co-creation sessions that were audio-recorded, and transcribed. The data analysis was performed involving the research team and the "experts by experience." Three themes emerged: 1) loneliness as a detrimental "state of the soul"; 2) loneliness reinforced by features of the aging process; and 3) loneliness builds more loneliness. MOAI LABS co-design process of digital solutions will embrace these experiences and involve frontline gerontological social workers who have experience with older adults' loneliness.

People with COPD present microbiota dysbiosis. Clinical implications of this finding are still unknown and need validation. Here, we tested the association between salivary microbiota and COPD and its ability to discriminate different types of patients. 67 patients with COPD (57male, 68±9y, FEV1pp 48±19, GOLD A-12, B-31, C-5, D-19) were characterised based on sociodemographic, anthropometric, clinical data and 16S rRNA profiling of their salivary microbiota. An unsupervised clustering analysis based on patients’ beta diversity was performed to query its relationship with the disease. Two major clusters (comprising 90% of individuals) differing drastically in severity were observed. Cluster1 aggregated all patients hospitalized in the previous year due to acute exacerbations, 71% of GOLD D patients and included a higher frequency of patients under oxygen therapy and heavier smoking history than Cluster 2 (Fig 1A). Furthermore, Cluster1 had a lower microbiota diversity (MW-U, p=0.008) (Fig 1B) and was enriched in Proteobacteria or Firmicutes, particularly Streptococcus. In contrast, Cluster2 was significantly enriched in Bacteroidetes, particularly Alloprevotella and Prevotella (Fig 1C). Saliva’s microbiota showed a strong association with COPD, especially in terms of severe exacerbations, supporting the use of salivary microbiota for further studies in this population. published

Bronchoalveolar lavage (BAL) and sputum samples are commony used to provide valuable information on airway microbiota of COPD but they are too invasive to be routinely collected. An interesting alternative would be the use of non-invasive samples from the upper airways but its validation is still lacking. Here, we have explored the merits of saliva to identify the typical profile of COPD microbiota. 70 patients with COPD (60 male, 68±9y, BMI 25.5±3.5, FEV1pp 48±16, GOLD A-12, B-32, C-5, D-21) and 50 healthy matched controls (42 male, 67±8y, BMI 27.6±3.8, FEV1pp 103±17) were characterised based on sociodemographic, anthropometric, clinical parameters and 16S rRNA profiling of their salivary microbiota. Microbiota composition was significantly different between healthy individuals and patients with COPD and could also descriminate moderate from severe patients. Healthy individuals were enriched in Alloprevotella and Prevotella, both Bacteroidetes’ genera, whereas moderate patients were enriched in Granullicatella and Lachnoanaerobaculum (Firmicutes) and severe patients were significantly enriched in Haemophilus (Proteobacteria) (Fig1.A). Furthermore, patients showed a significantly less diverse microbiota than healthy individuals (MW-U, p=0.001) (Fig1.B). Our results corroborate the findings reported previously using BAL and sputum samples encouraging further exploration of salivary microbiota as a potential disease biomarker. published

A pesquisa científica e a prática profissional têm vindo a demonstrar que as diferentes formas de expressão artística (música, teatro, dança etc.) revelam-se instrumentos especialmente eficazes no que diz respeito à intervenção social, seja na prevenção, reabilitação e tratamento de pessoas que apresentam problemas psicossociais, seja no seu potencial para capacitar e fortalecer o desenvolvimento social e pessoal de indivíduos numa comunidade. Por esse motivo, formar interventores sociais com recurso à arte torna-se, na nossa perspetiva, uma condição imperativa. Neste trabalho dá-se a conhecer os dados para Portugal do projeto "El Uso del Arte en la Formación y en la Intervención del Trabajo Social: Estudio Comparado entre España y Portugal" (INATS). Recorrendo à pesquisa documental, analisaram-se os planos de estudos das licenciaturas em Serviço Social em Portugal, lecionadas em 16 escolas públicas e privadas. Do trabalho de análise dos planos de estudo pode concluir-se que a Arte ainda está muito pouco presente nesta formação. Scientific research and professional practice have shown that the different forms of artistic expression (music, theatre, dance, etc.) are particularly effective instruments for social intervention, whether in the prevention, rehabilitation and treatment of people with psychosocial problems, or in their potential to empower and strengthen the social and personal development of individuals in a community. For this reason, training social interventionists using art becomes, in our perspective, an imperative condition. This paper presents the data for Portugal from the project "El Uso del Arte en la Formación y en la Intervención del Trabajo Social: Estudio Comparado entre España y Portugal" (INATS). Using documentary research, the syllabuses of undergraduate degrees in Social Work in Portugal, taught in 16 public and public schools, were analysed. From the analysis of the syllabuses it can be concluded that Art is still very little present in this training.

Chronic obstructive pulmonary disease (COPD) is influenced by environmental factors, such as indoor/outdoor contaminants. However, patients’ views on environmental exposure are little-known and this is an often-neglected topic in psychoeducational sessions in pulmonary rehabilitation (PR). We explored the views of patients with COPD about indoor/outdoor environment and its influence on their health and the impact of an environmental educational session within PR, on their daily living. Focus groups were conducted before and after community-based PR. An educational session was designed and included in PR after the first focus group. Data were analysed with thematic analysis. Four focus groups were conducted with 31 patients with COPD (71±8y; 74%male; FEV1 48±17pp; 45% GOLD2; 58% GOLDB). Prior to PR, 3 themes emerged: 1) “just seeing the tip of the iceberg” since some awareness existed but a feeling of probably not knowing the real impact was shared; 2) “feeling resigned” where patients acknowledged having poor strategies to avoid contaminants and felt there was little they could do; and 3) “willingness to learn” as they reported the need for an educational session to improve their knowledge on environmental exposures. After PR, 2 themes were found: 1) “gratefulness” where patients shared that the session was helpful for themselves and significant others; and 2) “personal change”, where patients expressed how their behaviour changed towards more health-enhancing strategies to deal with contaminants. Environmental education within PR is valued by patients and leads to specific behaviour changes to deal with contaminants’ exposure. Further attention to this topic is warranted. published

Background: The attachment theory aims to explain how the biological predispositions and the earlier experiences influences the mental health and psychopathology. Aims: To present a clinical case about Obsessive-Compulsive Disorder in a male adolescent with an anxious attachment style. A review about Obsessive-Compulsive Disorder and Attachment is also presented. Methods: A case report about an adolescent with Obsessive-Compulsive Disorder with comorbid Restrictive Food Intake Disorder and Generalized Anxiety Disorder is presented. The Father and Mother Attachment Questionnaire was applied to clarify the attachment style. A review of the theme was made exploring the connection between attachment and Obsessive-Compulsive Disorder, its approach and treatment. Results: The Father and Mother Attachment Questionnaire revealed an anxious attachment style in the adolescent. Conclusions: This case might ilustrate how an anxious attachment style could influence the pychological development. A psychopharmacological approach together with psychotherapy, involving the patient and family, seems to be the more adequate approach as highlighted in this case.

Background: In view of the high mortality for cardiovascular diseases, it has become necessary to stratify the main risk factors and to choose the correct diagnostic modality. Studies have demonstrated that a zero calcium score (CS) is characteristic of a low risk for cardiovascular events. However, the prevalence of individuals with coronary atherosclerotic plaques and zero CS is conflicting in the specialized literature. Objective: To evaluate the frequency of patients with coronary atherosclerotic plaques, their degree of obstruction and associated factors in patients with zero CS and indication for coronary computed tomography angiography (CCTA). Methods: This is a cross-sectional, prospective study with 367 volunteers with zero CS at CCTA in four diagnostic imaging centers in the period from 2011 to 2016. A significance level of 5% and 95% confidence interval were adopted. Results: The frequency of atherosclerotic plaque in the coronary arteries in 367 patients with zero CS was 9.3% (34 individuals). In this subgroup, mean age was 52 ± 10 years, 18 (52.9%) were women and 16 (47%) had significant coronary obstructions (> 50%), with involvement of two or more segments in 4 (25%) patients. The frequency of non-obese individuals (90.6% vs 73.9%, p = 0.037) and alcohol drinkers (55.9% vs 34.8%, p = 0.015) was significantly higher in patients with atherosclerotic plaques, with an odds ratio of 3.4 for each of this variable. Conclusions: The frequency of atherosclerotic plaque with zero CS was relatively high, indicating that the absence of calcification does not exclude the presence of plaques, many of which obstructive, especially in non-obese subjects and alcohol drinkers. Resumo Fundamento: Diante da alta mortalidade por doenças cardiovasculares, faz-se necessária a estratificação dos principais fatores de riscos e escolha correta da modalidade diagnóstica. Estudos demonstraram que escore de cálcio (EC) zero caracteriza baixo risco de eventos cardiovasculares. No entanto, a frequência de portadores de placa aterosclerótica coronária com EC zero é conflitante na literatura especializada. Objetivo: Avaliar a frequência de pacientes com placa aterosclerótica coronária, seu grau de obstrução e fatores associados em pacientes com EC zero e indicação para angiotomografia computadorizada de coronárias (ATCC). Métodos: Trata-se de estudo transversal, prospectivo, com 367 voluntários portadores de EC zero, mediante a ATCC, no período de 2011-16, em quatro centros de diagnóstico por imagem. Foi assumido nível de significância 5% e intervalo de confiança de 95%. Resultados: A frequência de placa aterosclerótica nas artérias coronárias dos 367 pacientes com EC zero foi de 9,3% (34 indivíduos); neste subgrupo, a média de idade foi 52 ± 10 anos, 18 (52,9%) eram mulheres e 16 (47%) exibiam obstruções coronarianas significativas (> 50%), dos quais 4 (25%) apresentaram placas em pelo menos dois segmentos. A frequência de não obesos (90,6% vs. 73,9%; p = 0,037) e de etilistas (55,9% vs. 34,8%; p = 0,015) foi significativamente maior nos portadores de placa, apresentando, cada variável, odds ratio de 3,4 para o desenvolvimento das referidas placas. Conclusões: A frequência de placa aterosclerótica com EC zero foi considerável, evidenciando, portanto, que a ausência de calcificação não exclui placa, muitas das quais obstrutivas, principalmente nos não obesos e etilistas.

Chromosomal rearrangements have been associated with multiple congenital abnormalities, including malformative syndromes and global developmental delay. The aim of this study was identification of candidate genes for a complex phenotype characterized by cardiopathy and autism, identified in an individual with a chromosome translocation t(4;7)(q21.1;p21.2). Since classical and molecular cytogenetic analyses have low resolutions, large-insert whole-genome sequencing (liWGS) was applied for identification and mapping of structural chromosomal alterations. By this approach, the 4q21.1 breakpoint was identified between genomic positions chr4:73,918,924-74,049,529 on 4q13.3, whereas the 7p21.2 breakpoint between chr7:13,184,731-14,536,001 [GRCh38/hg38]; suggesting the occurrence of deletions at both breakpoints. Additionally, a 473Kb deletion on 2p16.3 was also identified in the proband. Nucleotide-level resolution of the breakpoints and familial segregation analysis were carried out by amplification of the junction fragments and Sanger sequencing. At the 4q13.3 breakpoint, the 130Kb deletion erases four genes PF4, PPBP, CXCL5 and CXCL3, whereas at 7p21.2, the 1351Kb deletion removes the entire ETV1 and disrupts DGKB and the long non-coding intergenic (Linc) RNA AC011288.2. Furthermore, at this breakpoint region, genomic array analysis identified in the proband’s father a 742Kb deletion comprising DGKB and ETV but not the LincRNA AC011288.2. The maternally inherited 473Kb deletion on 2p16.3 removes the first 5 exons of NRXN1, a gene associated with Pitt-Hopkins like syndrome (OMIM #614325), susceptibility to schizophrenia and chromosome 2p16.3 deletion (OMIM #614332). Similar deletions have been reported with incomplete penetrance and variable expressivity. Several genes from the 7p21.2 breakpoint region and especially those affected by the deletion, DGKB, ETV1 and LincRNA AC011288.2, have been linked with cognitive, speech, language and auditory disorders. In conclusion, coinheritance of the maternally derived deletion on 2p16.3 and the deletion at the breakpoint of the der(7) on 7p21.2 appear to be the most contributively alterations for the proband’s phenotype. At the time, NRXN1, DGKB, ETV1 and LincRNA AC011288.2 are the most likely genes to be responsible for the proband’s phenotype, being those mainly characterised by cardiopathy and autism.

Objectivos: Caracterizar as referenciações efectuadas pelos Cuidados de Saúde Primários (CSP) à consulta da Unidade de Psiquiatria da Infância e da Adolescência (UPIA) do Centro Hospitalar de Vila Nova de Gaia/Espinho (CHVNG/E); avaliar a comunicação entre os dois níveis de cuidados. Tipo de Estudo: Observacional descritivo transversal. Local: UPIA do Serviço de Psiquiatria e Saúde Mental do CHVNG/E. População: A amostra incluiu todas as referenciações dirigidas à referida unidade provenientes dos CSP, via ALERT P1®, durante os anos de 2010 e 2011. Métodos: Procedeu-se à análise descritiva das variáveis género, idade, motivo de referenciação, prioridade da referenciação, prioridade atribuída pelo triador, motivo de recusa/devolução do pedido, tempo de espera, comparência do utente e qualidade da carta de referenciação. Resultados: A análise incluiu 980 referenciações (61,5% do género masculino). A faixa etária entre os 6-10 anos foi a mais referenciada (41,4%). O motivo mais referenciado foi “Sinais/sintomas do comportamento da criança” (31,9%). De todos os pedidos, 16,9% foram considerados urgentes pelo médico de família. Destes, 11,6% foram considerados prioritários pelo triador. De todas as referenciações, 11,3% foram recusadas/devolvidas, maioritariamente devido a informação insuficiente (36,1%). Cerca de 90% das referenciações consideradas prioritárias foram agendadas num prazo = 60 dias e quase 100% das restantes referenciações foram marcadas num prazo = 150 dias. Das 853 primeiras consultas marcadas, 10,5% das crianças faltaram à consulta e não pediram remarcação da mesma. Cerca de 20% das referenciações foram consideradas de boa qualidade e cerca de 14% de má qualidade. Conclusões: Os resultados sugerem que a articulação e a comunicação entre o médico de família e o psiquiatra da infância e da adolescência são eficazes, embora alguns aspectos possam ser melhorados, nomeadamente a adequação das prioridades atribuídas e a qualidade da informação dos pedidos de consulta. Objectives: To characterize the referrals from Primary Health Care (PHC) to the child and adolescent psychiatry consultation unit of the Centro Hospitalar de Vila Nova de Gaia/Espinho (CHVNG/E) and to evaluate the communication between these two levels of care. Study design: Cross-sectional. Setting: Child and Adolescent Psychiatry Unit of Psychiatry and Mental Health Service of CHVNG/E. Population: Our sample included all referrals from primary care to the referral unit, using ALERT P1®, in 2010 and 2011. Methods: Descriptive analyses were performed regarding gender, age, reason for referral, priority of the referral, priority given by the psychiatrist, reason for refusal or return of referral, waiting time, patient attendance, and quality of the referral letter. Results: Our analysis was based in 980 referrals (61.5% male). Patients aged 6-10 years were the most commonly referred (41.4%). The most frequent reason for referral was ‘signs and symptoms of child behaviour’ (31.9%). Of all referrals, 16.9% were considered urgent by the family doctor. Of these, 11.6% were considered as urgent by the psychiatrist. Of all referrals, 11.3% were refused or returned, mainly because of insufficient information (36.1%). About 90% of the referrals considered as priorities were scheduled within = 60 days and almost 100% of the remaining referrals were scheduled within = 150 days. Of the 853 scheduled first consultations, 10.5% of the children missed the consultation and did not ask for another appointment. About 20% of the referral letters were considered of good quality and about 14% were considered of poor quality. Conclusions: Our results suggest that communication between family doctors and child and adolescent psychiatrists is effective. Some aspects need improvement, particularly the definition of urgency and the quality of information in the referral letters.

As crianças que vivem expostas a violência em relações de intimidade são muitas vezes consideradas “vítimas indiretas” e durante muito tempo foi difícil enquadrá-las em algum tipo de abuso. Atualmente considera-se que o abuso emocional inclui a violência interparental que é testemunhada pelos menores. Apresenta-se o caso de uma criança exposta de forma recorrente a violência física e emocional do pai dirigida à mãe. Pretende-se com o caso clínico alertar para a necessidade de desenvolver estratégias de sensibilização para o rastreio ativo ao nível da consulta de pediatria e dos cuidados de saúde primários de situações de abuso, nomeadamente de exposição a violência em relações de intimidade. A violência doméstica é um crime público e inclui as situações de exposição a violência nas relações de intimidade, sendo este um aspeto determinante na transmissão intergeracional deste tipo de comportamento. É urgente quebrar estes ciclos de violência e orientar quer as vítimas, quer os agressores., NASCER E CRESCER - BIRTH AND GROWTH MEDICAL JOURNAL, Vol 26, No 3 (2017)

This study is an analysis of the Brazilian production of open educational resources (OER) through the perspective of teacher and student authorship. Starting with a bibliographical inquiry on the theme and a mapping of OER importance and usage for basic education in Brazil, as well as leaning on the history of open education, OER public policies, copyright laws, and Creative Commons, the research proposes the production of a recommendation guide on proper OER use for new concept co-production and co-learning. The production of such a guide can contribute to facilitate OER adoption and implementation processes in basic education. The relevance of applying OER in basic education is justified by its importance as an instrument to improve teaching by favouring co-learning through experience exchanges between teachers and students, between students, and between students and resources, as well as by providing more autonomy to students by allowing them to decide what, when, and through which medium to study.

This is an open-access article distributed under the terms of the Creative Commons Attribution License., Necroptosis is a regulated necrotic cell death that involves receptor-interacting protein kinases RIPK1 and RIPK3. Here, we report that edelfosine triggers a rapid and massive cell death in human glioblastoma cells with characteristics of necrosis. Only a minor proportion of edelfosine-treated cells underwent caspase-dependent apoptosis. Autophagy and a rapid influx of extracellular calcium into the cells had little impact on cell death. Levels of procaspase-8 were very low in necroptosis-prone glioma cells compared with the levels in other cancer cell types that underwent apoptosis upon edelfosine treatment. The RIPK1-dependent necroptosis inhibitors necrostatin-1 (Nec-1) and Nec-1s as well as siRNA-mediated silencing of RIPK3 inhibited edelfosine-induced necroptosis, resulting in increased caspase-dependent apoptosis in edelfosine-treated glioblastoma U118 cells. Inhibition of the RIPK3 substrate MLKL with necrosulfonamide also increased apoptosis in edelfosine-treated cells. These data support a major role for RIPK1 and RIPK3 in the induction of necrotic cell death and in the switch from necrosis to apoptosis following edelfosine treatment. These results indicate that the ether lipid edelfosine exerts a rapid necroptotic cell death in apoptosis-reluctant glioblastoma cells, suggesting that induction of necroptosis could constitute a new approach for glioblastoma therapy., This work was supported by grants from the Spanish Ministerio de Ciencia e Innovación (SAF2011-30518), Spanish Ministerio de Economía y Competitividad (RD12/0036/0065 from Red Temática de Investigación Cooperativa en Cáncer, Instituto de Salud Carlos III, cofunded by the Fondo Europeo de Desarrollo Regional of the European Union), Fundação para a Ciência e Tecnologia (SFRH/BD/46330/2008, Portuguese Ministério da Ciencia, Tecnología e Ensino Superior), European Community's Seventh Framework Programme FP7-2007-2013 (grant HEALTH-F2-2011-256986, PANACREAS), and Junta de Castilla y León (CSI052A11-2).

CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior As emoções interferem diretamente no processo de aprendizagem. Estudantes que se encontram em uma emoção prejudicial ao aprendizado não conseguem assimilar, da melhor maneira possível, o conteúdo que lhe é proposto. Neste sentido, esta pesquisa propõe um Modelo do Estudante baseado em emoções e perfis de personalidade com a finalidade de desenvolver o perfil afetivo do estudante em Ambientes Virtuais de Aprendizagem. Para validação computacional desta abordagem foram desenvolvidas a classificação dos perfis de personalidade e a predição das estratégias pedagógicas. A classificação dos perfis de personalidade foi realizada através de uma Rede Neural Artificial. Além disso, foi realizada uma análise experimental para verificar a base de treinamento mais adequada a partir de três conjuntos de treinamento, bem como, simulações com diferentes arquiteturas de Rede Neural. Como resultados, tem-se uma precisão de 97,28% para o reconhecimento geral dos nove perfis de personalidade. A definição das estratégias pedagógicas foi realizada por meio da associação das emoções básicas com os conselhos ao educador propostos na teoria perfis de personalidade. Posteriormente, utilizou-se a técnica Árvore de Decisão para induzir as regras de classificação que determinam as estratégias pedagógicas adequadas a cada perfil de personalidade. Desse modo, ao detectar uma emoção prejudicial ao aprendizado, o módulo pedagógico executará instruções através das informações contidas no Modelo do Estudante oferecendo ao estudante estímulo e/ou motivação personalizados de acordo com suas características individuais e, consequentemente, a aproximação da emoção que promova à aprendizagem. Emotions affect directly in the learning process. Students who are in a harmful emotion to learning can not assimilate in the best possible way, the content that is offered. Thus, this research proposes a student model based on emotions and personality profiles for the purpose of developing the student affective profile in a Virtual Learning Environment. For a computational validation modeling the classification of Personality profiles and Prediction of Pedagogical Strategies were developed. The classification of personality profiles was performed by an Artificial Neural Network. Furthermore, an experimental analysis to verify the most appropriate training basis from three sets of training was carried out, as well as simulations with different architectures of Neural Network. As a result, there were an accuracy of 97.28 % for general recognition of the nine personality profiles. The definition of pedagogical strategies was conducted by the association of basics emotions with the advice to the proposed educator in Personality Profiles theory. Was used the Decision Tree technique to induce classification rules in order to determine the most appropriate teaching strategies every Personality Profile. Thus, if a harmful emotion to learning is detected, the pedagogical module executes instructions through the information contained in the custom Student Model providing the stimulus student and/or motivation according to their individual characteristics and thus bring it emotion that promotes the learning.
