Such technologies have helped incorporate semantics in varied contents made available on the Web, including educational portals that are repositories of differentiated Learning Objects (LO), including educational videos. The MPEG-7 standard supports this process by providing a range of standardized instruments for the design of audiovisual contents in several granularities. However, the literature review on this topic pointed out that the searches of those contents by the user still need to be facilitated. In this sense, this qualitative, exploratory and descriptive study aimed to investigate how the incorporation of metadata into audiovisual contents of an Educational Semantic Portal can help retrieve semantically those contents and ensure its reuse. Thus, a prototype of a Semantic Educational Portal that enables users to register and retrieve those semantic contents was designed and constructed. This portal was assessed as recommended for the user interaction design. The results of this study allow us to state that the incorporation of metadata in educational audiovisual contents through related descriptors makes easier and precise the semantic search and the retrieval of specific information contained in such contents. However, this registration done manually takes longer to be carried out than the registration of an audiovisual content that does not use metadata, which suggests future research that would consider the need for more efficient systems to facilitate the registration process of audiovisual contents on educational semantic portals. / O aumento significativo da quantidade de informações nos portais web implicou no surgimento dos portais semânticos, que se servem dos padrões de representação das informações da World Wide Web Consortium (W3C), fundamentados em ontologias que auxiliam na organização, compartilhamento e reutilização dos conteúdos nesses ambientes. Essas tecnologias têm auxiliado na incorporação de semântica em variados conteúdos disponibilizados na Web, inclusive em portais educacionais que se constituem em repositórios de diferenciados Objetos de Aprendizagem (OA), inclusive vídeos educacionais. O padrão MPEG-7 auxilia nesse processo, fornecendo uma gama de instrumentos padronizados para o delineamento de conteúdos audiovisuais em diversas granularidades. No entanto, a revisão da literatura sobre esse tema apontou que as buscas desses conteúdos pelo usuário ainda necessitam ser facilitadas. Nessa direção, este estudo qualitativo, exploratório e descritivo teve por objetivo investigar como a incorporação de metadados em conteúdos audiovisuais de um Portal Semântico Educacional pode auxiliar a recuperar semanticamente esses conteúdos e garantir a sua reutilização. Para tanto, foi arquitetado e construído um protótipo de um Portal Semântico Educacional que possibilita aos usuários o cadastro e a recuperação desses conteúdos semanticamente. Esse portal foi avaliado de acordo com o recomendado para o design de interação com o usuário. Os resultados deste estudo permitem afirmar que a incorporação de metadados em conteúdos audiovisuais educacionais por meio de descritores relacionados facilita e precisa a busca semântica e a recuperação de informações especificas presentes nesses conteúdos. No entanto, esse cadastro feito manualmente leva mais tempo para ser realizado do que o cadastro de um conteúdo audiovisual que não utiliza metadados, o que sugere futuras investigações que considerem a necessidade de sistemas mais eficientes que facilitem o processo de cadastro de conteúdos audiovisuais em portais semânticos educacionais.

[pt] Tecnologias de vídeos bidimensionais (2D) têm evoluído rapidamente nos últimos anos. Apesar disso, elas não permitem uma visão realista e imersiva do mundo, pois não oferecem importantes dicas de profundidade para o sistema visual humano. Tecnologias de vídeo tridimensionais (3D) têm como objetivo preencher essa lacuna, provendo representações que permitem a reprodução de informações de profundidade em displays 3D. Embora a representação baseada em vídeos estereoscópicos ainda seja a mais utilizada até o momento, novas representações de vídeo 3D têm emergido, tais como MVV (Multi-view video), 2D plus Z (2D plus depth), MVD (Multi-view plus depth) e LDV (Layered-depth video). A integração de aplicações multimídia com mídias 3D tem o potencial de permitir novos conteúdos interativos, novas experiências com o usuário e novos modelos de negócio. Nesta tese, duas abordagens para a integração de aplicações multimídia em cadeias de transmissão de vídeo 3D fim-a-fim são propostas. Primeiro, uma abordagem que é compatível com cadeias de transmissão de vídeo 3D baseado em vídeos estereoscópicos é discutida. A proposta consiste em extensões para linguagens multimídia 2D e um processo de conversão de aplicações multimídia 2D para sua versão estereoscópica. Essa proposta não requer nenhuma alteração no exibidor de linguagens multimídia 2D para a apresentação de mídias estereoscópicas. Em uma segunda abordagem, extensões adicionais a linguagens multimídia também são propostas visando a integração de aplicações multimídia em cadeias de vídeo 3D baseado em profundidade (2D plus Z ou LDV). Além disso, uma arquitetura para a composição gráfica dessas aplicações, baseada no conceito de LDV e que permite a integração de objetos de mídia baseado em profundidade em exibidores de aplicações multimídias é apresentada. Como um exemplo de aplicação prática das proposta desta tese, ambas são implementadas e integradas em um sistema de vídeo 3D fim-a-fim baseado no Sistema Brasileiro de TV Digital. / [en] Two-dimensional video technologies have evolved quickly in the last few years. Even so, they do not achieve a realistic and immersive view of the world since they do not offer important depth cues to the human vision system. Three-dimensional video (3DV) technologies try to fulfill this gap through video representations that enable 3D displays to provide those additional depth cues. Although CSV (Conventional Stereoscopic Video) has been the most widely-used 3DV representation, other 3DV representations have emerged during the last years. Examples of those representations include MVV (Multi-view video), 2D plus Z (2D plus depth), MVD (Multi-view plus depth), and LDV (Layered-depth Video). Although end-to-end 3DV delivery chains based on those 3DV formats have been studied, the integration of interactive multimedia applications into those 3DV delivery chains has not yet been explored enough. The integration of multimedia applications with 3D media using those new representations has the potential of allowing new rich content, user experiences and business models. In this thesis, two approaches for the integration of multimedia applications into 3DV end-to-end delivery chains are proposed. First, a backward-compatible approach for integrating CSV-based media into 2D-only multimedia languages is discussed. In this proposal, it is possible to add depth information to 2D-only media objects. The proposal consists of extensions to multimedia languages and a process for converting the original multimedia application into its stereoscopic version. It does not require any change on the language player and is ready-to-run in current CSV-based 3DV delivery chains and digital receiver s hardware. Second, extensions to multimedia languages based on layered-depth media are proposed and a software architecture for the graphics composition of multimedia applications using those extensions is presented. As an example, both proposals are implemented and integrated into an end-to-end 3DV delivery chain based on the Brazilian Digital TV System.

Magister Psychologiae - MPsych / South African adolescents are engaging in sexual activities at an early age and with numerous sexual partners. Various factors such as adolescent physiology, identity development, peer influences and parent-child relationship, play a contributory role in this aspect. However, one of the less explored factors is the role of exposure to information and communication technologies containing sexual content, such as television, internet, music videos and cell phones. Adolescents have been shown to be heavy consumers of these devices. The study aimed at exploring the extent with which sexual content from these digital devices influences adolescents’ sexual perceptions and sexual behaviours. Participants comprised of 18 Grade 10 and Grade 11 learners, between ages 14 to 16 years, conveniently selected from one of the high schools in the Cape Peninsula. Two focus groups were conducted with an equal distribution of males and females in each group. Thematic analysis was utilized to describe participants’ experiences as reported in the text. Results indicated that participants regard ICT as influencing sexual attitudes and behaviour. More specifically, they believed ICT contributes greatly to early sexual initiation. Whilst some participants suggested that ICT encourages them to have many sexual partners with a “certain” physical image, some participants regarded this as irrelevant, viewing it as an individual’s choice. It was also found that participants viewed ICT’s unsafe sexual practices as not impacting in their use of contraceptives, hence they would not imitate such behaviour. Moreover, some participants viewed ICT as impacting on the manner in which they express themselves sexually, whilst others regarded this as untrue since they decide which sexual activities to engage in. The study addressed paucity of information regarding ICT and adolescent sexuality. To be more specific, it is recommended that future investigations should focus on a particular technology such as cell phones and the internet. Research should also focus on a specific domain regarding adolescent sexual attitudes, for example attitudes towards sexual initiation or the use of contraceptives.

Ce travail de recherche doctoral en sciences de l'information et de la communication se propose de construire une problématique autour de la web télévision et d'y répondre en tenant compte des spécificités de cette innovation technologique. Notre recherche se base sur une approche diachronique qui consiste à saisir la façon dont, en moins d'un siècle et demi, la télévision a identifié le bon message devant les médias et le public, pour nous arrêter sur les caractéristiques d'une réalité émergente, la web TV. Nous cherchons à explorer en quoi ce nouveau média révolutionne les moyens de communication audiovisuelle. Depuis les années 1950 l'information et par extension les médias représentent un objet d'étude toujours en émergence. La télévision a été l'objet de nombreuses recherches qui visaient à connaître son impact sur la société, la manière dont elle pouvait être utilisée pour influencer, pour informer, pour divertir, pour consommer. Elle a vite fasciné le public tout d'abord avec cette possibilité d'assister à un certain nombre d'évènements, d'avoir un potentiel d'ubiquité, procurant la sensation de voir l'histoire se dérouler sous ses yeux. Actuellement suite au développement de la technologie numérique, la télévision, les médias de masse par excellence sont en train de subir un changement de nature qui n'est pas sans incidence sur ce que l'on a l'habitude d'appeler la «culture télévisuelle». La convergence en cours des médias, facilitée par l'universalité du langage binaire, provoque une évolution technique du média qui devient progressivement un nouvel objet high-tech. Cette évolution de la nature technique de l'objet présente nécessairement des conséquences dans plusieurs secteurs d'activités et de domaines de recherche: la production, la publicité, la législation, la recherche et le développement, l'industrie, la sociologie, la psychologie, l'analyse de contenu, l'éducation, etc. Historiquement, en sciences sociales, la recherche sur les médias aux Etats-Unis et en Europe s'est orientée dès les années 1930 vers des études sur le contenu dans la perspective d'une analyse des effets.Dans ce contexte, dans un premier temps, nous traitons les éléments spécifiques de la communication audiovisuelle sur le support numérique, visant à déterminer la quantité de fonctionnalités qu'un produit médiatique sur ce support doit combiner afin de pouvoir se déclarer web tv. Ensuite, en raison de la rapidité de l'évolution accélérée et du caractère expérimental des médias numériques, nous allons traiter l'identification de la substance commune qui a un degré de résilience en termes de pratiques journalistiques en ligne et moins de l'apparence éphémère de la diversité, qui, peut conduire à l'impression que nous assistons à un schéma de soufflage final. Certains traits des web tv sont communs à ceux de la télévision traditionnelle à l'ère du web 2.0, parce que la télévision classique n'est pas restée figée concernant sa capacité de réinvention. Enfin, nous nous sommes intéressés à surprendre quelles sont les différences pas rapport à la télévision classiques et à déterminer si la prétention des promoteurs de la web tv d'avoir inventé une modalité complètement nouvelle est soutenable.Nôtre approche est praxéologique. Nous avons utilisé des instruments de travail adéquats : suivi des médias, observation, entretien, analyse de documents, questionnaire (discours sur la TV elle-même). / This doctoral research paper in Information and Communication Sciences intends to build a research issue around Web-television and to respond to it by taking into account the specificities of this technological innovation. Our research is based on a diachronic approach understanding how, in less than one century and half, television identified the right message to deliver to the media and the public, ending up with the characteristics of an emergent reality, that is Web-television. We are interested to explore how this new media is revolutionising audio-visual communication media. Since the 1950s, information, and by extension, media has represented a study object always emerging. Television was the object to many research aiming at knowing its impact on society, how it could be used in order to influence, to inform, to entertain, to consume. It rapidly fascinated the public firstly due to this possibility to attend a certain number of events, to have a potential of ubiquity, getting the feeling that one could see the history unfold before them. Nowadays, based on digital technology development, television, mass media par excellence, are about to undergo a change having an impact on the nature of what we commonly call “television culture”. The on-going media convergence, helped by the universal binary language, generates a technical evolution of the media thus gradually becoming a new high-tech object. This technical evolution of the object has necessarily consequences in numerous activity areas and research fields: manufacturing, advertisement, legislation, research and development, industry, sociology, psychology, content analysis, education etc. Historically, in social sciences, research on the media in the U.S. and in Europe has been oriented since the 1930s towards studies based on content from the point of view of an analysis of the effects.In the light of this, at first, we analyse the elements specific to audio-visual communication on digital support, aiming at defining the amount of features that a media product of this type of support should combine in order to be able to call itself Web TV. Moreover, due to the rapid progression and to the experimental nature of digital media, we shall discuss about identifying the common substance having a degree of resilience in terms of online daily habits and less about the apparently short life of diversity that may lead to the impression that we are witnessing a one final breath. Some characteristics of the Web television are the same with those of the traditional television from Web 2.0, because the classical television didn't remain motionless in terms of its capacity to reinvent itself. Finally, we were interested in tracing the differences between Web television and classical television, and in determining whether Web television promoters are right when they claim having invented a completely new method.We used a practise-based approach. We used adequate research tools: media monitoring, observation, interview, document analysis, questionnaire (speech on television itself).

O tratamento é baseado em cirurgia, radioterapia e quimioterapia, isoladas ou em conjunto e, são responsáveis por importantes sequelas que afetam negativamente as atividades diárias dos pacientes, contribuindo para uma diminuição na qualidade de vida. Entretanto, as informações prévias ao tratamento e a compreensão destas complicações pelos pacientes são insuficientes para prepará-los para o tratamento. Na literatura médica a utilização de vídeos educativos é documentada como uma ferramenta importante na transmissão de informações prévias a tratamentos complexos, demonstrando resultados promissores na melhoria da compreensão dos pacientes. No entanto, a utilização de vídeos educacionais esclarecendo as complicações do tratamento direcionadas aos pacientes com câncer de cabeça e pescoço é escassa, não havendo nenhum artigo que se dedique exclusivamente a estes pacientes. Portanto, o objetivo deste estudo foi avaliar o efeito de um vídeo educativo sobre a melhoria da compreensão dos pacientes com câncer de cabeça e pescoço submetidos à radioterapia sobre as complicações do tratamento. Para isto, a equipe de oncologia multidisciplinar, composta por membros do Centro de Oncologia do Hospital dos Fornecedores de Cana (CEON-HFC) e da Faculdade de Odontologia de Piracicaba (FOP-UNICAMP), produziu um vídeo de 6 minutos sobre os efeitos colaterais da radioterapia na região de cabeça e pescoço. Um estudo clínico controlado foi realizado com dois grupos: o grupo controle (n = 19), que recebeu informação verbal, e o grupo de vídeo (n = 19), que recebeu informação verbal e assistiu ao vídeo. Para medir o nível de compreensão, bem como levantar dados socioeconômicos, dois questionários foram dados a ambos os grupos, um antes do início da radioterapia e outro após o término da radioterapia. Trinta e oito pacientes foram incluídos no estudo. Trinta e um pacientes (81,58%) tinham um nível de escolaridade inferior ao ensino médio. Todos os pacientes do grupo de vídeo responderam corretamente por que eles foram submetidos à radioterapia. Por outro lado, três pacientes (15,79%) do grupo do controle não conhecia o motivo para o tratamento. Apenas um paciente (5,26%) do grupo de vídeo tinha dúvidas sobre o tratamento, em comparação a sete do grupo de controle (36,84%). Como conclusão, o estudo demonstra que a utilização de vídeo educativo pode melhorar a compreensão do paciente com câncer de cabeça e pescoço sobre o tratamento com radioterapia e seus efeitos colaterais, independente de seu nível de escolaridade / Abstract: The head and neck cancer is the sixth most common type worldwide and is an increasing concern for public health agencies around the world. The treatment is based on surgery, radiotherapy and chemotherapy, alone or combined, and are responsible for important consequences that negatively affect patients' daily activities, contributing to a decrease in quality of life. However, the information prior to treatment and understanding of these complications by patients are insufficient to prepare them for treatment. In the medical literature the use of educational videos is well documented as an important tool in transmitting complex information prior to treatment, demonstrating promising results in improving understanding of the patients. However, the use of educational videos explaining the complications of treatment directed to patients with head and neck cancer is scarce, and there is no article devoted exclusively to these patients. Therefore, the aim of this study was to evaluate the effect of an educational video on improving the understanding of patients with head and neck cancer undergoing radiotherapy on complications of treatment. For this, the multidisciplinary oncology team, composed of members of the Oncology Center of the Hospital of Sugarcane Suppliers (CEON-HFC) and Piracicaba Dental School (FOP-UNICAMP), produced a 6 minute video about the side effects of radiotherapy in the head and neck. A controlled clinical study was conducted with two groups: a control group (n = 19) who received verbal information and the video group (n = 19) who received verbal and watched the video. To measure the level of understanding and raise socioeconomic data, two questionnaires were given to both groups, one before the start of radiotherapy and another after the end of radiotherapy. Thirty-eight patients were included in the study. Thirty-one patients (81.58%) had an education level less than high school. All patients in the video group answered correctly why they underwent radiotherapy. Furthermore, three patients (15.79%) in the control group did not know the reason for the treatment. Only one patient (5.26%) in video group had doubts about the treatment, compared to seven in the control group (36.84%). In conclusion, this study demonstrates that the use of educational video can improve understanding of the patient with head and neck cancer on treatment with radiotherapy and its side effects, regardless of their level of education / Doutorado / Patologia / Doutor em Estomatopatologia

Para utilizar um vídeo é preciso que o professor selecione e o avalie conforme as características pedagógicas e técnicas que são relevantes para o contexto de utilização em sala de aula. No entanto a seleção e avaliação dos materiais audiovisuais estão acontecendo intuitivamente pelos professores. Diante da ausência de mecanismos e critérios que contribuam para a seleção dos vídeos, construiu-se uma taxionomia para classificação de vídeos direcionados á educação matemática, que objetiva apoiar o professor na seleção destes materiais. Objetivou-se, também, investigar e compreender como ocorrerá a avaliação e seleção dos vídeos pelos professores de matemática através da taxionomia construída. Com tais objetivos, buscou-se responder a seguinte questão: como a utilização de uma taxionomia de vídeos pode apoiar a tomada de decisão na escolha e seleção de vídeos didáticos no contexto da educação matemática? No âmbito desta pesquisa, abordou-se como tema a inserção das Tecnologias de Informação e Comunicação no ambiente escolar, o vídeo na educação e especificamente na educação matemática, propostas de classificação e avaliação de vídeos didáticos. Devido às características e objetivos da pesquisa, adotou-se a abordagem qualitativa através de uma pesquisa de campo, onde colaboraram, como sujeitos da pesquisa, nove professores de matemática do ensino fundamental das escolas públicas de Juiz de Fora, realizando um experimento de avaliação de vídeos e entrevista. Com a análise dos dados obtidos no experimento, verificaram-se as dificuldades dos professores no uso de vídeos nas atividades matemáticas, bem como, o papel da taxionomia em um processo de avaliação de vídeos e sua contribuição para a construção do guia de seleção e avaliação de vídeos didáticos destinados aos professores de matemática. / In this study we investigated the organization of teaching practice math teacher of elementary school regarding the use of educational videos in the context of mathematics education. To play a video it is necessary that the teacher select and evaluate as the pedagogical and technical characteristics that are relevant to the context of use in the classroom. However the selection and evaluation of audiovisual materials are intuitively going by teachers. In the absence of mechanisms and criteria to support the selection of videos, constructed a taxonomy for classifying videos directed mathematics education, which aims to support the teacher in the selection of these materials. The objective was to also investigate and understand how occur evaluation and selection of videos by mathematics teachers through the built taxonomy. With these objectives, we sought to answer the following question: how the use of a taxonomy videos can support decision-making in the choice and selection of educational videos on mathematics education context? Within this research, we approached the theme of integration of Information and Communication Technologies in the school environment, the video in education and specifically in mathematics education, classification proposals and evaluation of instructional videos. Due to the characteristics and objectives of the research, we adopted a qualitative approach through field research, where cooperating as research subjects, nine math elementary school teachers from public schools in Juiz de Fora, performing an evaluation experiment videos and interviews. With the analysis of data obtained in the experiment, there were the difficulties of teachers in the use of videos in mathematical activities, as well as the role of taxonomy in a process of evaluation of videos and their contribution to the construction of the selection guide and review of educational videos aimed at math teachers.

The thesis deals with a topic of virtual relaxation and the contrast between idealized landscape and everyday reality. The theme of landscape compensation is very comprehensive and widely interacts with and impacts on psychological and cultural levels. For example, when images of nature represent a place of denied primary purity or the unreachable paradise. I draw my inspiration from YouTube channel phenomenon of relaxation videos which depict several hours’ long static views of the ideal landscape with authentic sound in the background. The aim of the work is to prepare a happening with a video recording, when the absurdly long journey in search of the ideal will not be transferable.

„Hast Du Schwierigkeiten, die richtige Ansprache für Millennials zu finden?“ Dann empfiehlt die Onlinemarketingplattform www.onlinemarketing.de sich die perfekte Videowerbung für die Generation Y anzusehen. Im Video sind „hippe, junge Menschen in Zeitlupe“ zu sehen, die fröhlich sind, sich frei fühlen, lachen, bunte Haare haben, gern mit Freunden zusammen sind und Spaß an der Konversation haben, fotografieren, posten, liken und teilen. Natürlich werden im Video die Klischees überzogen und auch aufs Korn genommen. Aber die Kernaussage stimmt mit der Definition der Millennials überein: Sie sind technikaffin, legen Wert auf ihre Selbstverwirklichung und verfolgen eine hohe Leistungsorientierung. Sie studieren und investieren in die Ausbildung. Es ist aber auch die Generation, die mit dem Smartphone groß geworden ist. Sie beziehen nahezu alle Informationen aus dem Internet und halten sich täglich über mehrere Stunden in den sozialen Medien auf. Die Autorin setzt sich in ihrer Dissertation mit dem Thema auseinander, wie diese Generation sich Wissen aneignet. Sie möchte in Experimenten nachweisen, dass die Millennials anders lernen, weil sie aus der Informationsflut selektieren müssen. Sie wollen ihr Wissen möglichst effektiv, auf das Wesentliche reduziert, präsentiert bekommen. Das sind Erfahrungen der Autorin aus der Lehre. Dieses Paper fasst Hypothesen und Gedanken zusammen, die provokant und als mögliches Zukunftsszenario beschrieben werden. Dabei geht es einerseits um die Distribution. Wo müssen Lehrvideos veröffentlicht werden, dass sie von der lernenden Zielgruppe wahrgenommen und angenommen werden. Auf der anderen Seite geht es auch um den Content selbst und wie er dargestellt wird – strukturell und visuell. Die Autorin zieht dafür Parallelen zum Journalismus sowie zum Marketing.

The method of physiological measurement of sexual arousal to erotic stimuli is often used in sexological research. However, there is no concept of form of these stimuli to induce maximum possible sexual response from a person. It seems that female static physical attractiveness is an important factor in perception of the female, but it could be also female nonverbal behavior, dynamic attractiveness, which could influence perception and which could either enhance of reduce the overall attractiveness of a female. In the whole concept of attractiveness, there could be two components: "physical attractiveness" and "sexual desirability". In this diploma thesis, we address this problem and we compared static and dynamic stimuli with focus on specific behavior. The study had two parts. We used photographs of clothed and naked women and videos of castings of potential actresses in erotic movies; materials are available online for free. In the study I we used 90 photographs of faces and clothed bodies and found that there is a difference between physical attractiveness and sexual desirability. Moreover, face was a predictor of physical attractiveness and body was a predictor of sexual desirability. In study II we used sexually explicit videos and found that nonverbal behavior has just a minor influence on...

In an organization such as a university with many institutions and new employees the onboarding process is a key activity for the employee life cycle. This study examines the possibilities and limitations of further digitalization of the process by including new formats for information.  The format in question is 360-videos. These videos can be viewed both on head mounted displays which are used to create a 3D environment but also on computer screens which allows the content to be accessible to those that lack the 3D equipment. Based on semi-structured interviews with HR-employees at the university the study has found there to be many activities that are suitable for the format but also a few limitations concerning planning for and executing the development of new content for the onboarding process. The conclusions drawn from the results in this study and previous studies on the topic shows that implementation of 360-videos would lead to standardized content concerning many of the activities that cannot be done digitally by conference calls or two-dimensional videos. These activities are today done in person and at the responsibility of the new hires closest manager which leads to the activities being time consuming and can vary in terms of content.
