Depuis plus d'une vingtaine d'années, la qualité de l'éducation au Vietnam est souvent remise en cause et le système éducatif fait l'objet de plusieurs débats et initiatives de rénovation, sans pour autant atteindre les résultats attendus. Innover par le numérique et intégration internationale figurent parmi les priorités fixées dans la politique nationale, notamment au niveau d’enseignement supérieur. Beaucoup de programmes d’enseignement supérieur au Vietnam ont été évalués par l'ASEAN University Network (AUN). Parmi de nombreux critères de cette démarche d'évaluation, 15 sous-critères concernent de près ou de loin l'usage des TIC dans les formations. L’analyse des résultats de quatre programmes vietnamiens évalués en 2009 et 2011 montre qu'il existe une différence dans la perception réelle des sous-critères liés aux TIC entre les parties prenantes internes et les évaluateurs externes de ces programmes. À partir de ce constat, nous élaborons un instrument de mesure susceptible de permettre à tous les acteurs internes et externes d’un programme de formation d’identifier ce qui contribue à la satisfaction des étudiants vis-à-vis de l’usage des TIC dans les cours dispensés. Différents modèles existants (TAM, CEQ, SCEQ, eLEQ) ont été intégrés et adaptés dans le contexte de l’évaluation des programmes par l’AUN. Des enquêtes ont été menées auprès de plusieurs centaines d’étudiants de cinq programmes évalués en 2009, 2011 et 2014. Les résultats permettent de confirmer la validité et l’ajustement du modèle que nous proposons. / Since more than twenty years, the educational quality has been subject to lots of public debates in Vietnam. Several renovation solutions was adopted without achieving the expected results. As the country has strongly integrated the international market, ICT-based innovation and international quality assessment become first priorities fixed in the national educational policies. A lot of training programmes have been assessed by the ASEAN University Network (AUN). Among the criteria used in this quality-assurance assessment, encompassing 15 sub-criteria that relate more or less to the use of the ICT in the educational activities. We analyzed the results of four Vietnamese programmes assessed in 2009 and 2011 and founded that there is a significant difference of the perception about the ICT use quality between the internal stakeholders and the external assessors in these programmes. From this revelation, we aim to elaborate a measurement instrument which may help all of the programme’s internal or external stakeholders to identify the factors contributing to the students’ satisfaction about the ICT use in their degree courses. Some existing models such as TAM, CEQ, SCEQ, eLEQ were integrated in the context of AUN-QA assessment at the programme level. The survey was conducted at five Vietnamese programmes assessed in 2009, 2011 and 2014, with 453 full responses. The data analysis confirms the validity of our proposed measurement model.

O dermatófito Trichophyton rubrum é um fungo filamentoso, antropofílico, que invade tecidos queratinizados causando infecções superficiais e cutâneas. Algumas drogas são usadas para o tratamento das dermatofitoses, sendo o ácido undecanóico (AUN) uma delas. O AUN é o mais tóxico dos ácidos graxos saturados de cadeia média, utilizado como medicamento de uso tópico. O estudo de expressão gênica e mecanismos regulatórios são fundamentais para ampliar o conhecimento dos mecanismos moleculares envolvidos na resposta à exposição a estes agentes citotóxicos. Portanto, o objetivo deste trabalho foi caracterizar os mecanismos moleculares envolvidos no processo adaptativo da exposição ao ácido undecanóico, através da análise global do transcriptoma e mecanismos regulatórios como o processamento alternativo. Para tanto o micélio de T.rubrum foi submetido ao ácido undecanóico por 3 e 12 h de exposição, em triplicata biológica, e o RNA resultante foi submetido ao sequenciamento por RNAseq. O sequenciamento gerou aproximadamente 58 milhões de reads por biblioteca, as quais foram filtradas e alinhadas com o genoma de referência utilizando-se os softwares FASTQC e bowtie2, respectivamente. A análise de expressão gênica diferencial foi feita por meio do pacote do Bioconductor DESeq e, para esta análise, foi utilizada a amostra de 0h como referência. Foram identificados 492 genes diferencialmente expressos em resposta ao AUN, sendo 385 e 210 genes modulados em resposta a 3 e 12 horas de exposição, respectivamente. Estes genes estão relacionados a vários processos celulares envolvendo transporte transmembrana, degradação de xenobióticos, metabolismo de lipídeos e aminoácidos, secreção de enzimas proteolíticas e patogênese, sugerindo que o AUN ativa duas principais vias de sobrevivência em resposta a este agente estressor, a degradação e o efluxo da droga. Posteriormente, foram realizadas as análises de processamento alternativo quanto ao uso diferencial de exons por meio do algoritmo HTSeq e DEXSeq e retenção de introns utilizando-se algoritmos construídos na linguagem Perl. Os genes envolvidos em algum tipo de processamento alternativo estão relacionados com funções metabólicas variadas como tradução, transporte vesicular, metabolismo lipídico, biogênese ribossomal, sequência de ligação ao DNA, regulação da transcrição e processamento do pré-mRNA. Estes resultados contribuem para uma melhor compreensão dos mecanismos moleculares envolvidos na resposta de sobrevivência perante a exposição ao AUN. / The dermatophyte Trichophyton rubrum is a filamentous fungus, anthropophilic that invades keratinized tissue causing superficial infections on the skin. Some drugs are used for the treatment of dermatophytosis, being the undecanoic acid (AUN) one of them. The AUN the most toxic of the saturated medium chain fatty acids, is used as a topical medicine. The study of gene expression and the regulatory mechanisms are fundamental to understand the molecular mechanisms involved in response to exposure of these cytotoxic agents. So, the aim of this study was to characterize the molecular mechanisms involved in the adaptive process of the exposure to undecanoic acid, by the global analysis of the transcriptome and regulatory mechanisms such as alternative splicing. To this end, the mycelium of T. rubrum was exposed to undecanoic acid for 3 or 12 hours in biological triplicate, and the resulting RNA was sequenced by RNA-Seq. The sequencing generated approximately 58 million of reads per library, which were filtered and aligned with the reference genome using the softwares and Bowtie2 and FASTQC, respectively. The analysis of differential gene expression was performed through the Bioconductor package DESeq and, for this analysis, we used as reference sample the 0h time. We identified 492 differentially expressed genes in response to UDA, being 385 and 210 genes modulated in response to 3 and 12 hours of exposure, respectively. These genes are related to various cellular processes involving the transmembrane transport, xenobiotics degradation, lipids and amino acids metabolism, secretion of proteolytic enzymes and pathogenesis, suggesting the activation of two major survival pathways in response to this stressor, degradation and drug efflux, by UDA. Also, the alternative splicing analysis was performed through the differential use of exons using the algorithms HTSeq and DEXSeq and intron retention using algorithms built in Perl language. The genes involved in some kind of alternative splicing are associated with various metabolic functions such as translation, vesicular transport, lipid metabolism, ribosomal biogenesis, DNA binding sequence, transcription regulation and processing of pre-mRNA. These results contribute to increase the knowledge of the molecular mechanisms involved in the survival response upon exposure to the AUN.

Abstract. The overall aim of this study is to examine the Neo-Gnostic teachings of Samael Aun Weor (1917-1977). The research question will inquire his main ideas in relation to syncretism, cosmology, and sexology. Accordingly, based on the theoretical perspectives of Antoine Faivre, the gnostic doctrine of Samael Aun Weor is summarized, compared and examined in the light of the definitions of western esotericism. The purpose is on one hand to make an exploration of a relatively unknown esoteric author and on the other hand to place his vast teachings and interpretations within the esoteric context and in relation to the new era discourse. Methodically, a qualitative text analysis will be used to explore several books written by Samael Aun Weor which are further analysed with the help of secondary sources. The study concludes that the Neo-Gnostic ideology of Samael Aun Weor, despite being placed by scholars within the new era discourse, additionally matches within the framework of classical esotericism and that furthermore reveals revived and combined perspectives with interpretations that have seldom been transmitted before.
