DEVELOPMENT OF AN ADJUSTABLE SUTURE TECHNIQUE FOR TRABECULECTOMY

This research presents a new design of an adjustable suture that could provide a better intraocular pressure (IOP) control in the post treatment of trabeculectomy surgery and limit associated complication with the current suturing techniques. A better control in tension suture brings a great deal of advantages to this surgical technique compared with the traditional adjustable suture. A length adjustment can be added in advance to a 10-0 nylon suture which enables suture tension to be released during the postoperative period of trabeculectomy surgery. This adjustment has a D-ring geometry made of 10-0 nylon suture adhered to a 10-0 nylon surgical suture which is used to close the scalar flap. The D ring was adhered with about 180 microdroplet of Loctite 4311that was found to form a strong joint to connect the D ring to the main 10-0 nylon suture and strong enough to carry the added tension instead after cutting the central suture between the two joints of the D ring. The geometry of adjustment is the key factor of maintaining the IOP at the normal range and keeping the scleral flap tight enough and secure so that aqueous humor continues to percolate under the subconjunctiva. It has been found that a 365, and 450 µm length extensions can release suture tension postoperatively and relieve the intraocular pressure within the eye by 33, and 66% respectively. The fabrication process of the new adjustable suture was divided into two steps: fabrication of micro jig and forming microdroplets. A micro jig was fabricated in order to form and bond a precise length extension to the new design of the adjustable suture. In addition, a new liquid separation technique has been followed in this study in order to generate micro adhesive droplets as small as 50µm for bonding the new adjustable suture structure.

Designing an interactive laboratory experiment to investigate buoyancy

Laboratory classes provide a visual and practical way of supplementing traditional teaching through lectures and tutorial classes. A criticism of laboratories in our School is that they are largely based on demonstration with insufficient participation by students. This provided the motivation to create a new laboratory experiment which would be interactive, encourage student enthusiasm with the subject and improve the quality of student learning.

The topic of the laboratory is buoyancy. While this is a key topic in the first-year fluids module, the laboratory has been designed in such a way that prior knowledge of the topic is unnecessary and therefore it would be accessible by secondary school pupils. The laboratory climaxes in a design challenge. However, it begins with a simple task involving students identifying some theoretical background information using given websites. They then have to apply their knowledge by developing some equations. Next, given some materials (a sheet of tinfoil, card and blu-tack), they have to design a vessel to carry the greatest mass without sinking. Thus, they are given an open-ended problem and have to provide a mathematical justification for their design. Students are expected to declare the maximum mass for their boat in advance of it being tested to create a sense of competition and fun. Overall, the laboratory involves tasks which begin at a low level and progressively get harder, incorporating understanding, applying, evaluating and designing (with reference to Bloom’s taxonomy).

The experiment has been tested in a modern laboratory with wall-mounted screens and access to the internet. Students enjoyed the hands-on aspect and thought the format helped their learning.

The use of cheap materials which are readily available means that many students can be involved at one time. Support documentation has been produced, both for the student participants and the facilitator. The latter is given advice on how to guide the students (without simply giving them the answer) and given some warning about potential problems the students might have.

The authors believe that the laboratory can be adapted for use by secondary school pupils and hope that it will be used to promote engineering in an engaging and enthusing way to a wider audience. To this end, contact has already been made with the Widening Participation Unit at the University to gain advice on possible next steps.

Constructive Synthesis of Memory-Intensive Accelerators for FPGA From Nested Loop Kernels

Field-programmable gate arrays are ideal hosts to custom accelerators for signal, image, and data processing but de- mand manual register transfer level design if high performance and low cost are desired. High-level synthesis reduces this design burden but requires manual design of complex on-chip and off-chip memory architectures, a major limitation in applications such as video processing. This paper presents an approach to resolve this shortcoming. A constructive process is described that can derive such accelerators, including on- and off-chip memory storage from a C description such that a user-defined throughput constraint is met. By employing a novel statement-oriented approach, dataflow intermediate models are derived and used to support simple ap- proaches for on-/off-chip buffer partitioning, derivation of custom on-chip memory hierarchies and architecture transformation to ensure user-defined throughput constraints are met with minimum cost. When applied to accelerators for full search motion estima- tion, matrix multiplication, Sobel edge detection, and fast Fourier transform, it is shown how real-time performance up to an order of magnitude in advance of existing commercial HLS tools is enabled whilst including all requisite memory infrastructure. Further, op- timizations are presented that reduce the on-chip buffer capacity and physical resource cost by up to 96% and 75%, respectively, whilst maintaining real-time performance.

Effekter av Internet of Things : Scenariobaserad studie som beskriver inledande effekter av Internet of Things i en verksamhet

Med begreppet "Internet of Things" menas att ett objekt ur den riktiga världen blir en del av internet. Tunabyggen i Borlänge planerar att implementera ett sådant informationssystem som med hjälp av sensorer och en ständig internetuppkoppling håller uppsikt över temperatur och luftfuktighet i utvalda lokaler. Det är ett enkelt system som till synes inte har så stora effekter på den nuvarande verksamheten. De ekonomiska effekterna går ofta att räkna på i förhand men effekterna på personal, miljö och rutiner kan glömmas bort. Vi har därför med detta examensarbete undersökt vilka inledande effekter som kan tänkas uppkomma efter implementering av ett nytt informationssystem med "Internet of Things" funktionalitet i en verksamhet. Detta sker inom kategorierna ekonomi, arbetsmiljö, miljöpåverkan och systemförvaltning. För att kunna besvara detta har vi gjort en fallstudie baserad på en scenariometodik som består av fyra faser. Fas 1, där vi fick vårt Case och skapade en förståelse för scenariofältet. Fas 2, där vi identifierade nyckelfaktorer. Detta har gjorts genom en litteraturstudie samt intervju med berörd personal på Tunabyggen. Fas 3, där analysen av dessa nyckelfaktorer skedde genom nulägesanalys och framtidsanalys av nyckelfaktorer. Fas 4, där vi genererade scenarier av de analyserade nyckelfaktorerna. Det har sedan gjorts en SWOT-analys för att belysa styrkor, svagheter, möjligheter och hot. Resultatet visar tydliga tecken på att det kommer att bli många effekter för Tunabyggen efter implementering av det nya informationssystemet som yttrar sig i alla kategorier. Slutsatsen är att vid implementation av ett informationssystem som detta är effekterna många. Detta är något som vi anser bör beaktas av alla verksamheter som har tankar på att införskaffa ett nytt informationssystem. De bör inte bara utvärdera informationssystem rent ekonomiskt utan borde ta i beaktning att det finns ett antal andra faktorer som har en avgörande roll om implementation av informationssystem ska bli lyckad.

Thesis (Ph.D.)--University of Washington, 2016-08

Estudios de predicción en series temporales de datos meteorológicos utilizando redes neuronales recurrentes

[ES] En los últimos años, en el campo de las energías renovables, la energía eólica ha sido una de las que mas se ha desarrollado e invertido. La importancia de las predicciones de viento radica en la ayuda que aportan para planificar y anticiparse a los valores futuros que afectarán al sistema, ayudando a gestionar la adquisición de los recursos necesarios con antelación suficiente. Recientemente se han desarrollado nuevas arquitecturas de redes recurrentes que resultan muy prometedoras para realizar predicción. En este trabajo se probará y experimentará con dichas arquitecturas para realizar distintas predicciones de la velocidad del viento en un horizonte de corto y muy corto plazo a partir de datos de series temporales de viento.

Markets, Depots and Sales Tables: The Women's Institute's Rural Retailing

In 1917 the Coventry Evening Telegraph noted that the problems of ‘surplus garden produce’ had arisen and that ‘smallholders were being encouraged to group together in order to bring their supplies in quantity to market. Women’s Institutes have been formed, and these arrange for the opening of a market for a certain number of hours one day a week’. WIs, which had begun being formed under the auspices of the Agricultural Organisation Society from 1915 could be seen to be one of the earliest examples of Farmers Markets. These rural women were to improve the food supply in wartime when there was a food crisis; shortages, queues, price rises and in 1918 the introduction of rationing. The WIs encouraged food saving and preservation their markets enabled small holders, cottage gardeners and allotment holders to find a financial non- exploitive outlet for their produce. Markets and retail outlets developed in a number of towns or even cities in rural areas: Worcester, Leamington Spa and Lichfield and in post-war Britain depot trading centres were set up in some county towns Maidstone in Kent in 1919, Winchester in 1920. Between them they provided rural women with a retail space initially for their garden produce and then in time for the preserves, baking and craftwork. Jam, cakes, toys, knitted toys and garments even a wedding trousseau were ordered or sold through these retail outlets. The Markets were not restricted to WI members and often sold work produced by small­holders, the disabled and ex-servicemen. Membership required buying at least one share; as they were a co-operative venture there was a limit on the number of shares it was possible to purchase. Sales tables at some monthly WI meeting provided yet another retail outlet for rural women. This paper will explore the significance of these retail opportunities to rural women: as a chance to earn much needed cash, in placing a value on domestic labour and as an indication that when looking at rural women’s lives, in first half of the twentieth century, divisions between being consumers and producers of food and domestic products may be more fluid than it is something assumed.

Os programas de incentivo à cultura e o processo de fomento às organizações culturais no Rio Grande do Norte: o caso da Casa da Ribeira em Natal

Since the emergence of the first demands for actions that were intended to give greater attention to culture in Brazil, came the first discussions which concerned the way the Brazilian government could have a positive influence in encouraging the culture, as is its interaction with the actors interested and involved with the cause. During the military dictatorship, there were programs which relied on the direct participation of the State to ensure that right, from the viewpoint of its support and implementation of public resources in developing the "cultural product" to be brought to society in its various forms of expression - all this, funded by the government. It is an example of "EMBRAFILMES" and "Projeto Seis e Meia", continued until the present day in some regions of the country, though maintained by entities not directly connected with the administration or the government. However, it was from the period of democratization and the end of the dictatorship that the Brazilian government began to look at the different culture, under its guarantee to the society. Came the first incentive laws, led by "Lei Sarney" Nº 7.505/86, which was culture as a segment which could receive foreign assistance in order to assist the government in fulfilling its public duty. After Collor era and the end of the embargo through the encouragement of culture incentive laws, consolidated the incentive model proposed in advance of Culture "Lei Sarney" and the federal laws, state and local regimentares as close to this action. This applies to the Rouanet Law (Lei Rouanet), Câmara Cascudo Law (Lei Câmara Cascudo) and Djalma Maranhão Cultural Incentive Law (Lei de Incentivo à Cultura Djalma Maranhão), existing in Natal and Rio Grande do Norte. Since then, business entities could help groups and cultural organizations to keep their work from the political sponsorship under control and regiment through the Brazilian state in the form of their Cultural Incentive Law. This framework has contributed to the strengthening of NGOs and with the consolidation of these institutions as the linchpin of Republican guaranteeing the right to access to culture, but corporate social responsibility was the one who took off in the segment treated here, through the actions of Responsibility Cultural enterprises arising from the Cultural Organizations. Therefore, in the face of this discourse, this study ascertains the process of encouraging the Culture in Rio Grande do Norte from the Deviant Case Analysis at the Casa da Ribeira, the main Cultural Organization that operates, focused action in Natal in order to assess the relationships established between the same entity and the institutions which are entitled to maintain the process of encouraging treated in this study - Enterprise, from the viewpoint of corporate sponsorship and Cultural Responsibility and State in the form of the Laws Incentive Funds and Public Culture Incentive

Disortografia

É significativo o número de alunos brasileiros que apresentam, em maior ou menor grau, problemas relacionados com a escrita, independentemente do seu ano de escolaridade ou formação. Dentro das salas de aulas essa é uma realidade que todos nós conhecemos. E por conhecer essa realidade é que reconhecemos que isto influencia de uma forma negativa a formação de nossos estudantes. Na verdade, se estas dificuldades não forem detetadas atempadamente, os custos serão enormes, quer em termos pessoais quer em termos sociais, já que essas dificuldades tendem a se manter na vida adulta. O papel do professor assume-se, deste modo, fundamental na identificação precoce destes casos e na adequação do processo de ensino-aprendizagem na senda do sucesso escolar. No entanto, não raras vezes o seu trabalho é dificultado ou pelo desconhecimento da problemática em questão ou pela falta de uma política educativa que, a nível dos gestores escolares, permita potenciar a sua atividade de docente. É neste contexto que surge o presente trabalho que tem por objetivo analisar as conceções e as práticas pedagógicas na área da disortografia. Para tanto, abordaremos o conceito de disortografia e suas implicações na leitura e escrita, com ênfase no último aspecto, já que a dificuldade se dá justamente na grafia. No sentido de melhor compreender a realidade de algumas escolas do ensino fundamental e médio do Brasil, foi conduzido um estudo exploratório, com recurso à técnica do questionário, tendo sido inquiridos 31 professores e 11 gestores de escolas públicas e privadas. Os resultados evidenciaram, entre outros aspetos, algum desconhecimento sobre disortografia bem como algumas divergências entre estes dois agentes educativos quanto às características desta perturbação e quanto às melhores estratégias e medidas educativas para crianças com este diagnóstico. Com base nestes resultados é proposto um esboço de um programa de intervenção junto da comunidade educativa.

Teaching down or learning up

Résumé : L'élément important que cette thèse sous-tend est que l'enseignement efficace n'est pas seulement constitué de techniques et de méthodologie, mais plutôt d'attitude et d'approche envers l'enseignement. Ceci ne veut pas nécessairement dire que plusieurs méthodes d'enseignement reçues dans un cours avec l'intention d'optimaliser les mécanismes de transmission et d'assimilation de la matière sont inappropriées. Cependant, l'absence de ce que nous pourrions définir comme un ton pédagogique est essentiel, c'est-à-dire, qu'une attitude positive à la productivité autant vis-à-vis de la matière à transmettre que vis-à-vis de l'individu impliqué dans "l'acte" de réception versus la découverte, aura davantage de succès. Toute autre méthode sera complètement inefficace, inaccessible, voire même inutile. D'emblée, dans l'hypothèse de départ, l'argument principal présente une attitude générale d'enseignement à divers échelons ; soit au niveau secondaire ou collégial qui est inappropriée, incomplète ou négative. En d'autres mots, cette approche thérapeutise l'éducation. Dans l'exercice de cette approche, l'enseignant ou l'enseignante adopte plutôt le rôle d'un thérapeute que celui d'un éducateur. De ce fait, le professeur en situation a une approche plutôt de thérapeute que celle de maître-précepteur et que la matière présentée est souvent diluée, et réduite à des niveaux d'apprentissage accompagnés de carences notoires et d'échecs académiques. Les attentes d'une performance dans le milieu académique sont souvent des plus modestes. Cette même tendance d'une éducation à la baisse est évidente aussi dans le processus d'évaluation. Il est certain que dans les disciplines non scientifiques, l'évaluation formative a grandement suivi l'évaluation normative conduisant le précepteur, tour à tour, dans une évaluation dormative dans laquelle l'effort et l'intention remplacent les aptitudes et les habilitées réelles. Si l'approche pédagogique est vraiment l'élément crucial de l'éducation, il Importe que l'approche générale influence le climat de l'éducation contemporaine, de fait, devienne un palliatif contre-productif souvent réhabilitant. De plus, cette pseudo-thérapie d'où d'écoule une attitude exigeante envers l'enseignant et l'apprenant dont le fondement est la reconnaissance des impératifs culturels qui en sont le reflet et le corps doit-être affirmé et transposé dans la réalité. Cette dernière comprend des attentes très poussées en ce qui concerne la performance en classe et aussi le respect de la matière qui contient la présentation routinière et fondamentale; renouveau intense du processus d'évaluation qui fournira des standards communs et des objectifs externes dans l'évaluation du travail de l'étudiant. Cette connaissance et domestication empirique que nous présente Vygotsky dans un climat contemporain qu'il a expliqué ces termes comme "des zones de développement proximales" basées sur la doctrine suivante que le bon apprentissage précède le développement et que conséquemment s'ensuit une pédagogie d'apprentissage plutôt qu'une pédagogie centrée sur l'apprenant. L'application significative de ces derniers principes ou de ces épistémologiques s'imbriquent dans une situation d'apprentissage ascentionnel dont la structure est détaillée et considérée par différentes perspectives de la recherche qui suit.||Abstract : The central tenet of this thesis is that effective teaching is not only and perhaps not primarily a matter of technique and methodology but of attitude and approach. This is not to say that diverse methods of classroom instruction intended to optimize the mechanics of transmission and the assimilation of data are inappropriate but that in the absence of what we might denominate as a certain pedagogical tone. that is, a productive attitude toward both the material to be conveyed and the individuel engaged in the 'act' of reception-and-discovery, even the most powerful methods will be differentially unavailing or, at best, inefficient. Given this initial assumption, the argument proceeds that the general attitude toward instruction currently in place at the secondary echelons, that is, on the high school and college levels, may be popularly represented as a 'teaching down' approach, in other words, as one which seeks to therapeuticize education. In practice this means that the teacher tends to manifest in situ more as a therapist than as a preceptor, that the material to be presented is frequently diluted or scaled down to perceived levels of cognitive (dis)ability (as is also the case with the rate of instruction), and that performance expectations in the current pedagogical milieu are commonly quite modest. The same downward trend is evident in assessment protocols as well. Certainly in the nonscientific disciplines, normative evaluation has been widely succeeded by formative evaluation, leading in turn to a peculiar kind of dormative evaluation in which intangibles such as effort and intention may deputize for realized ability. If pedagogical approach is indeed the crucial element in instruction, and if the general approach that pervades the contemporary climate of instruction is indeed counter-productively remedial or rehabilitory, that is, therapeutic, then it should follow that a more demanding attitude toward teaching and learning founded on the recognition of the culturel imperative which teaching both reflects and embodies needs to be re-affirmed and translated into practice. This latter would entail the maintenance of high expectations with regard to classroom performance, a respect for the material which precludes its routine mitigation or debasement, a renewed insistance on grading protocols that provide an external, 'objective' or communal standard against which the student's work can be measured, the empirical acknowledgment or domestication of what Vygotsky has termed "the zone of proximal development," based on the doctrine that good learning proceeds in advance of development, and conséquently, a learning-centered rather than learner-centered pedagogy. The meaningful application of this latter set of principles or epistemological gradients comprises the 'learning up' situation whose structure is excunined in some détail and considered from various perspectives in the ensuing.

Développement à visée clinique d’une prothèse vasculaire décellularisée de faible diamètre produite par génie tissulaire

Il existe un besoin clinique pour les prothèses vasculaires de faible diamètre (< 6 mm), notamment pour effectuer des pontages vasculaires. Les prothèses synthétiques de faible diamètre, n’ayant pas d’endothélium, sont sujettes à la thrombose. Ainsi les chirurgiens préfèrent utiliser les vaisseaux autologues des patients. Pour cela, la veine saphène est de loin la plus utilisée. Cependant, de nombreux patients n’ont pas de vaisseaux adéquats, soit parce qu’ils ont déjà été utilisés, soit parce qu’ils sont malades. Pour pallier ce manque, le LOEX a développé un substitut vasculaire reconstruit en laboratoire par la méthode d’auto-assemblage du génie tissulaire. Ces substituts, faits à partir de cellules humaines, ont une longue période de production et ne peuvent être faits à l’avance ni préservés. L’objectif principal de cette thèse est le développement d’une prothèse vasculaire de faible diamètre facilitant le transfert du laboratoire vers la clinique. S’inspirant de travaux antérieurs, les travaux focalisent sur des prothèses obtenues à partir de fibroblastes dermiques humains puis décellularisés. Comme la réponse immunitaire se fait principalement contre les cellules et non pas contre la matrice extracellulaire, la décellularisation permet de gagner une compatibilité immunitaire inter-individu, voire inter-espèce. Ainsi, des prothèses ont été implantées dans six rats pendant six mois sans immunosuppression avec un taux de succès de 83%. Les explants présentaient une infiltration cellulaire suggérant la formation d’une nouvelle media recouverte d’un endothélium. Par ailleurs, nous avons démontré qu’il était également possible de produire des prothèses de grandeur et diamètre adéquats pour une utilisation clinique. Ces prothèses ont été préservées durant trois mois sans altérer leurs propriétés mécaniques. Nous avons également endothélialisé des vaisseaux qui ont ensuite été conditionnés en bioréacteur durant une semaine. Le processus entraînait une compaction de la matrice extracellulaire et un gain dans la résistance à la traction du matériau. En conclusion, les prothèses vasculaires décellularisées offrent deux avantages majeurs facilitant ainsi les essais précliniques et accélérant leur transfert du laboratoire vers les patients.

Novas tecnologias para o controle da giberela do trigo na safra 2014 no sudoeste do Paraná

The work consists in wheat production system and the evolution of damage caused by wheat scab. The study considers the lack of resistant cultivars to the disease, the low efficiency of chemical control and the presence of mycotoxins in grains. The study aimed to confirm the effectiveness of fungicides prothioconazole and metconazole; prove the bar deposition efficiency with nozzles directed jets the side of the ear resulting in full coverage of trapped anthers; prove the viability of using a warning system (application after the start of flowering before the onset of rains provided for future 24-48 hours and try to improve the efficiency in controlling scab. The experiment was conducted in the experimental field of Technological University Federal do Paraná in the city of Pato Branco, Paraná, conducted in two seasons, the first established on May 6, 2014 and the second on 21 May 2014. It was used to cultivate Amethyst field of OR Improvement seeds, . Passo Fundo, Rio Grande do Sul Treatments consisted of a control without fungicide application and one and two applications of prothioconazole + 17.5% trifloxystrobin (Fox) 500 ml / ha; metconazole 8.0% + pyraclostrobin 13% ( Opera Ultra) 750 mL / ha In the evaluation, second season, metconazole + pyraclostrobin with two application statistically was the treatment that showed a lower incidence in spikes reducing from 100 to 63.3%;. metconazole + pyraclostrobin performed better also in reducing the incidence of spikelets, 80.3% to 34.7%; the control ears had better results in the second season with two applications of metconazole + pyraclostrobin; in spikelets, in his first season, metconazole + pyraclostrobin with two application resulted in better control with 67%; with two applications of metconazole + pyraclostrobin gave the highest yield even under climatic conditions favorable to disease; metconazole + pyraclostrobin in both seasons showed superior efficiency in controlling FHB giving greater weight gain; with two application of both fungicides, the hectoliter weight was 81 and 79, respectively, each fungicide; the application of fungicides was made in advance of expected rain, occurring seven days of rain and a total volume of 85,2mm the first time, and 16 days of rain and an accumulation of 400 mm in the second period; the test efficiency can be confirmed when the direction of the spray jets launched wings coupled in double nozzle bodies perpendicular to the target upright reaches the sides of the spike. The metconazole + pyraclostrobin proved the most effective fungicide against the prothioconazole + trifloxystrobin in wheat scab control in the 2014 harvest.

Impact of Thresholds and Load Patterns when Executing HPC Applications with Cloud Elasticity

Elasticity is one of the most known capabilities related to cloud computing, being largely deployed reactively using thresholds. In this way, maximum and minimum limits are used to drive resource allocation and deallocation actions, leading to the following problem statements: How can cloud users set the threshold values to enable elasticity in their cloud applications? And what is the impact of the application’s load pattern in the elasticity? This article tries to answer these questions for iterative high performance computing applications, showing the impact of both thresholds and load patterns on application performance and resource consumption. To accomplish this, we developed a reactive and PaaS-based elasticity model called AutoElastic and employed it over a private cloud to execute a numerical integration application. Here, we are presenting an analysis of best practices and possible optimizations regarding the elasticity and HPC pair. Considering the results, we observed that the maximum threshold influences the application time more than the minimum one. We concluded that threshold values close to 100% of CPU load are directly related to a weaker reactivity, postponing resource reconfiguration when its activation in advance could be pertinent for reducing the application runtime.

Dimensão intercultural da linguagem não-verbal em contexto de sala de aula: um estudo com uma turma de espanhol

O presente relatório tem como principal objetivo desenvolver a competência da interculturalidade no âmbito da linguagem não-verbal de alunos portugueses, do 3º ciclo do ensino básico, com frequência à disciplina de Espanhol. A Linguagem não-verbal tem um contributo preponderante na comunicação e, quando há a pretensão de se conhecer outra cultura, é forçoso que se interpretem os diferentes sistemas onde cada indivíduo se integra e interage, porque comunicar eficazmente com o outro implica um conhecimento das estruturas simbólicas e dos códigos culturais intrínsecos, não só à cultura de um outro específico, mas também ao seu próprio contexto sociocultural, histórico-cultural e económico-cultural. Este trabalho faz apologia de um ensino intercultural que promova o diálogo entre culturas, sabendo-se de antemão que há representações que devem ser desconstruídas, bem como uma linguagem não-verbal específica que pode interferir na pragmática da interculturalidade. Trata-se de uma investigação-ação demarcada por dois momentos distintos: um primeiro estudo vocacionado para a consciencialização dos alunos de que a comunicação não-verbal é uma competência que se ensina e se aprende e um segundo estudo dedicado a aspetos culturais diferenciadores, entre Espanha e Portugal, na linguagem não-verbal , com enfoque nos gestos culturais e no tratamento do tempo. Os dados a analisar são: a transcrição de uma aula gravada, onde foram aplicados vários recursos audiovisuais e escritos consentâneos com as unidades programáticas, e as respostas a um questionário dirigido à turma de intervenção e a uma turma de nacionalidade espanhola que com ela colaborou. A implementação destas atividades/estratégias didáticas permitiu concluir que, por um lado, os alunos interpretam os diferentes códigos não -verbais à luz de uma perspetiva universal, por outro, há uma forte influência de estereótipos herdados e filtrados, a partir de diferentes marcos histórico-temporais. Este estudo sobre o não- verbal também se traduziu num alicerce bastante hábil para motivar à aprendizagem em geral e para enriquecer o conhecimento sobre a cultura do outro e a sua própria cultura, através da aquisição de códigos não- verbais comunicativo-funcionais.
