A concepção desse tipo de narrativa estende-se, do meio impresso até a plataforma móvel tablet, graças aos autores Muniz Sodré e Ferrari (1986), Benjamin (1994), Díaz Noci (2011), Rita Paulino (2012) e Suzana Barbosa (2013). Essa fundamentação teórica vai ao encontro do objetivo de compreender como as narrativas são construídas no tablet, a partir de características peculiares aos meios digitais e móveis: multimidialidade, hipertextualidade, gênero e tactilidade. Para tanto, lançou-se mão de dois produtos: a revista digital O Globo a Mais e o aplicativo do Jornal do Commercio de Pernambuco, observados em diferentes períodos de 2013. O corpus de análise é composto de 10 narrativas do O Globo a Mais e quatro do Jornal do Commercio. A hipótese norteadora subentendia que os produtos analisados utilizariam os recursos multimídia pertinentes ao tablet. Envidencia-se, desta forma, pelo menos dois produtos distintos: o shovelware, cuja ideia é apresentada por Fidalgo e Canavilhas (2009); e o autóctone, conceituado por Barbosa, Silva e Nogueira (2012). De forma generalizante, ressaltam-se alguns aspectos estruturais das narrativas apresentados nos dois produtos: narrativas lineares com algumas variações; convergência de conteúdos; o processo de remediação e a apropriação da subjetividade, utilizada com maior intensidade em reportagens em profundidade dos autóctones, representados aqui por O Globo a Mais, o que permite fazer uma analogia ao jornalismo de revista desenvolvido pela revista O Cruzeiro nas décadas de 40, 50 e início de 60 (CASADEI, 2013). / The guiding problem of this study looked for the characteristics which could be identified, in the journalistic narratives written for the tablet platform. The conception of this type of narrative extends from the printed media to the tablet mobile platform, thanks to authors like Muniz Sodré and Ferrari (1986), Benjamin (1994), Díaz Noci (2011), Rita Paulino (2012) and Suzana Barbosa (2013). This theoretical fundamentation meets the objective of comprehending how the narratives are constructed on the tablet, based on characteristics which are peculiar to digital and mobile media: multimediality, hypertextuality, genre and tactility. Therefore, two products were analysed: the digital magazine O Globo a Mais and the application of the Jornal do Commercio of Pernambuco, observed in different periods in 2013. The corpus of the analysis is composed of 10 narratives from O Globo a Mais and four from the Jornal do Commercio. The guiding hypothesis implies that the analysed products would use multimedia resources pertinent to the tablet. We evidence, therefore, at least two distinct products: the shovelware, the idea of which is presented by Fidalgo and Canavilhas (2009); and the autochthon, conceptualized by Barbosa, Silva and Nogueira (2012). In a general way, we highlight certain structural aspects of the narratives presented in both products: linear narratives with some variations; convergence of content; the process of remediation and the appropriation of subjectivity, used more intensely in deep news in the autochthones, represented here by O Globo a Mais, which allows us to make an analogy to the magazine journalism developed by the magazine O Cruzeiro in the 40s, 50s and early 60s (CASADEI, 2013).

Die Inzidenz und Prävalenz von Krebserkrankungen präsentiert sich in den vergangenen Jahren ungebrochen hoch. Durch die stetige Optimierung der Versorgung werden Betroffenen neuartige Optionen offeriert. Moderne Onkotherapie zeichnet sich durch sektorenübergreifende Kooperation aus. Diese komplexen Versorgungskonzepte können durch innovative Technologien simplifiziert werden. Vorliegende Arbeit erörtert die Frage nach der Umsetzbarkeit Tablet-gestützter Screenings in der Routine der Strahlenmedizin. Die Erfassung der ESAS-Items und des Unterstützungsbedarfs ermöglichte nach dem Vorbild kanadischer Versorgungskonzepte definierte Aussagen zur Qualität der medizinischen Versorgung. Im Rahmen der Studie erhielten Tumorpatienten vor der perkutanen Radiotherapie (T1) ein Tablet-gestütztes Symptom-Screening. Das Tablet-Screening wurde von den Teilnehmern bezüglich Bedienung und Nutzerfreundlichkeit evaluiert. Nach Abschluss der Radiotherapie erfolgte eine telefonische Nachbefragung der Teilnehmer (T2). Insgesamt partizipierten 332 Krebspatienten am Tablet-Screening. 79 potentielle Studienprobanden nahmen nicht teil. Als Hauptursachen zeigten sich fehlende Zeit (21,5%), die Teilnahme an sonstigen Studien (20,3%) und zu hohe psychische Belastungen (17,7%). Der Anteil der Screening-Teilnehmer mit fundierten Vorkenntnissen im Umgang mit Tablet-PCs (15,7%) war gering. Probanden mit Tablet-Vorerfahrungen waren signifikant jünger als Unerfahrene. Anwendung und Nutzerfreundlichkeit erlangte hohe Zustimmung. Die wenigen (21,7%) Befürworter konventioneller Stift-Papier-Fragebögen waren signifikant älter. 219 Screening-Teilnehmer stellten ihre ausgewerteten Symptom-Fragebögen weiteren Auswertungen zur Verfügung. Der Performance-Status wurde von Patient und Mediziner eher divergent bewertet (ĸ=0,254). Von T1 zu T2 nahm der Anteil positiv gescreenter Probanden ab. Kurativpatienten markierten bei den ESAS-Items Müdigkeit, Kurzatmigkeit und Sonstiges signifikante Symptomverbesserungen. Bei Palliativpatienten zeigte Kurzatmigkeit signifikante Verbesserung, Depressionen hingegen signifikante Verschlechterung. Der schwächste Unterstützungsbedarf (23,3%) wurde beim ,,Bedarf an Informationen beim Erstellen von Patientenverfügungen‘‘ registriert. Die BUKA-Studie konnte die Chancen Tablet-gestützter Befragungen in der Routine der Radioonkologie darstellen. Das Screening markierte durchgängig positive Bewertungen sowie große Akzeptanz. Die positiven Ergebnisse deckten sich mit denen anderer Studien bezüglich EDV-gestützter Datenerhebung. Die oftmals nicht ausreichendende Zeit zur Studienteilnahme war jedoch nicht auf eine zu zeitintensive Bedienung von Tablet-PCs zurückzuführen. Die Anzahl der Screening-Items sollte der kurzen Wartezeit der Strahlenambulanz angepasst werden. EDV-Screenings sollten darüber hinaus zukünftig bereits von zuhause absolviert werden. Die zunehmende Technisierung des Alltags lässt den Anteil PC-erfahrener Patienten weiter ansteigen. Die Einführung EDV-gestützter Versionen bietet eine effektive Möglichkeit des Patienten-Monitoring als Grundlage multidisziplinärer onkologischer Versorgung. Infolge der zunehmenden PC-gestützten Verarbeitung hochsensibler Patientendaten ist die Gewährleistung vollkommener Datensicherheit dringend notwendig. Im Gegensatz zu anderen Arbeiten präsentierte das Studienkollektiv überwiegend Kurativpatienten mit gutem Allgemeinzustand. Trotz geringerer Symptombelastung konnten auch hier die positiven Effekte der Radiotherapie dargestellt werden. Der hohe Unterstützungsbedarf erschien oftmals dem mangelnden medizinischen Verständnis der Betroffenen geschuldet. Kurativpatienten äußerten deutlich mehr Interesse aktiv an der Therapie teilzuhaben. Palliativpatienten erschienen durch das Übermaß an Therapien entkräftet. / In recent years the incidence and prevalence of carcinosis remained unchanged high. The continous improvement of patient centred care offers unknown possibilities. Modern cancer therapy is distinguished by overlapping cooperation. These extensive treatment options can be simplified by innovative technology. The study in hand investigates the implementabilitiy of a tablet screening in the field of radiooncology. Aquiring data on the ESAS Items and on the individual request of support as done in the Canadian cancer support system enables us to give evidence. In the present study tumor patients were screened before receiving percutane radiotherapy (T1) on a special symptom screening scale via tablet. The participants also evaluated the tablet screening on handling and usability. After the radiotheray the participants were questioned again via phone interview. In total 332 cancer patients took part in the tablet screening. 79 potential participants didn’t participate. The main reasons were the lack of time (21,5%), the participation in other studies (20,3%), and the high psychic strain (17,7%). The the number of participants with a previous knowledge in the use of tablet-computer was low (15,7%). Furthermore, they were significantly younger than the participants with that hat no previous knowledge in the use of a tablet. Handling and usabilityshowed high acceptance. The few supporters of conventional paper-pencil -quetionnaires were significantly older. In total 219 screening patients did consent the further evaluation and analysis of their screening results. Patients and physicians showed divergent results in theassessment of the patient’s performance status (k=0,254). The rate of participants with positive screening results decreased from T1 to T2. In the ESAS items fatigue, dyspnoea and other problems curative patients showed significant symptom improvement. Patients with palliative treatment also represented with significant improvemet in dyspnoea whereas the rate on depression increased significantly. Patients showed the lowest interest in the provision on information on making an advance health care directive (23,3%). The BUKA study was able to represent the opportunities of tablet screening in the routine of radiooncology. The tablet screening did resilt in an overall positive feedback and demonstrated high rate of acceptance. Similar positive results were also showen in several previous studies concerning the use computerized questionnaires. The participants complaints on the lack of time did not refer to the use of the computerized questionnaire itself but on the provided amount of time for the questionaire itself. In the future, the amount of screening items should be adjusted to the amount of waiting time in the ambulance of the radiooncology. Furthermore, computerized screening should be considered to be already done at home. The upcoming computerization in the daily routine will increase rate people with previous knowledge on computerized systems and applications even further. The implementation of computerized systems provides the opportunity of a very effective patient monitoring as a foundation vor multidisciplinary oncological treatment. As a result of the increasing digitalization of patient data the data protection is extremely important and future challenge but must be basic prerequisite. In contrast to other studies our patients predominantly represented a good performance status. Despite the low symptom stress the positive effects of a radiotherapy could be illustrated here as well. The high demand of support seemed to be due to the lack of understanding of medical information. Curative patients showed significantly more interest in taking actively part in their therapy whereas patients with palliative treatment seemed to be rather exhausted with the excess of palliative treatment options.

The human mind is a churning engine, processing all forms of sensory input. Information that reaches these senses is powerful, facilitating and deepening understanding. Animations access sight. They provide a rich visual model that portrays not only information about the system graphically, but they also present information about the relationships and interactions in that model over time. However, the complexity of today's software for constructing animations limits their use and isolates animations to a small set of scenarios. One such eliminated scenario is being able to create and manipulate animations in real time, while a conversation takes place. The human mind comprehends from manipulation, trial, and error. Animations are productions. Instructors cannot manipulate and recreate animations within the time constraints of a classroom. Developers cannot recreate animations within the time constraints of a meeting. This thesis explores the engineering of a modeling environment prototype for creating animated models. By building an environment designed to leverage the capabilities of Microsoft's Tablet PC operating system, this thesis contributes a new approach to creating animations and visualizations. This prototype demonstrates a pen-based user interface that decreases the time and effort required to create an animation by enabling users to create an animation by simply drawing a model and animating it. The Tablet PC hardware and software provide developers with the capabilities necessary to create software that works as naturally as the pen and paper. With the Tablet PC's Ink technology, users can draw models and simply draw the paths where the objects in that model should follow. This thesis explores the design of the environment, the research prototype named Model Pad, and explores its importance, its contribution, and its unique design based on the capabilities of the Tablet PC. As mobile computers become increasingly central to the workplace, the ability to create animations quickly and easily while talking with others, while presenting in front of an audience or a class, or while working with a team of engineers allows animation to become a natural part of the way we visually communicate information. The Model Pad environment is merely a first step in the direction of creating fully pen-based modeling and animation tools. The concepts it builds form the foundation of understanding how to express animations that are more complex. This thesis and the Model Pad environment provide the initial framework for building pen-based animation tools on the Tablet PC, allowing simple models to be expressed in methods as simple as using a pen and paper. This solution enables people to construct simple models in real time, enabling a rebirth of the power of animation for education and engineering design. / Master of Science / The human mind is a churning engine, processing all forms of sensory input.

Electronic textbooks are different from ebooks (electronic books) in that they allow the user to go beyond just reading material on a computer screen. Electronic textbooks encourage the user to accomplish all of the operations typically performed with a hardcopy text in addition to some functions not possible with paper books. With electronic textbooks users can make annotations in the textbook with e-ink; mark important sections; search over the ink, the text, or even the scanned images; look up items in online dictionaries or encyclopedias; perform interactive reinforcement drills; view simulations; and many other operations afforded by the computing power of the underlying computer and the reach of the Internet connection. These operations encourage students to engage in active reading. The VText framework is designed to provide many of the desired features of an e-textbook in such a way that it produces pedagogical value rather than just convenience for students. Many so-called e-textbook solutions available today provide few features beyond those possible with hardcopy textbooks. The VText framework is built as an add-in to Microsoft's note-taking program, OneNote. The add-in provides features that facilitate the use of OneNote as a reader and as an educational tool while leaving in place OneNote's strengths in note-taking, collaboration, and search. / Master of Science

Seit Beginn des neuen Jahrtausends haben Tablets in der medizinischen Lehre zunehmend an Bedeutung gewonnen. In dieser Studie wurden ein Tablet-basiertes und ein Dozierenden-zentriertes Lehrformat im Rahmen eines Radiologie-Seminars verglichen. Ziel war es, vergleichende Erkenntnisse über selbsteingeschätzten und objektiven Lernzuwachs und empfundene didaktische Qualität zu erlangen und mögliche Einflüsse des Charismas der Dozierenden sowie der studentischen Technikaffinität auf diese Variablen zu untersuchen. Von n=366 Studierenden wurden über drei Semester hinweg Daten zu studentischer Technikaffinität generell sowie didaktischer Qualität und Zufriedenheit mit den Seminaren abhängig vom Lehrformat erhoben. Im letzten Studiensemester nahmen die Studierenden zudem eine Selbsteinschätzung ihres Lernzuwachses vor und legten ein Wissens- und Bildinterpretationstestat sowie eine Einschätzung des Charismas der Dozierenden ab. Mittels Maximum-Likelihood Faktorenanalyse erfolgte eine Strukturaufklärung der didaktischen Qualität und des Charismas. Pearson-Korrelationskoeffizienten wurden zur Untersuchung möglicher Korrelationen zwischen den Variablen berechnet. Ein Strukturregressionsmodell des Charismas der Dozierenden, der studentischen Technikaffinität und der didaktischen Qualität wurde erstellt und daraus eine lineare Regressionsgleichung abgeleitet. Dem Tablet-basierten Lehrformat wurden signifikant höhere Werte in didaktischer Qualität und studentischer Zufriedenheit zugeschrieben. Das Dozierenden-zentrierte Format schnitt hingegen in selbsteingeschätztem und objektivem Lernzuwachs signifikant besser ab. Ausschließlich im Tablet-basierten Unterricht korrelierte das Charisma der Dozierenden mit dem selbsteingeschätzten Lernzuwachs. Die studentische Technikaffinität wirkte sich in diesem Format stärker auf die didaktische Qualität aus. Zudem wurden gute Organisation, eindeutige Lernziele und adäquate Lernformvariation als bedeutsame Faktoren identifiziert. Diese Studie hebt die Relevanz des dozentischen Charismas und der studentischen Technikaffinität für die Sicherstellung hoher didaktischer Qualität in Tablet-basiertem Unterricht hervor. Sie zeigt zudem die Wichtigkeit der Kongruenz von Lernzielen, Lehrkonzept und Prüfungsmethode dieses Lehrformats auf, um hohe Studienleistungen sicherzustellen. Die untersuchten Faktoren sollten bei Entwurf digitaler Lehrkonzepte über spezifische Messinstrumente objektiviert und bei Bedarf geschult oder angepasst werden, um eine erfolgreiche Integration digitaler Medien in die medizinische Lehre zu gewährleisten. / Since the beginning of the new millennium, tablets have become increasingly important in medical teaching. In this study, a tablet-based and a teacher-centred teaching format were compared in the context of a radiology seminar. The aim was to gain comparative insights into estimated and objective learning gain and perceived didactic quality, and to investigate possible influences of teacher charisma and student digital affinity on these variables. Data on student digital affinity in general as well as didactic quality and satisfaction with the seminars depending on the teaching format were collected from n=366 students over three semesters. In the last semester, students also estimated their learning gain, completed a knowledge and image interpretation test and rated teacher charisma. Maximum likelihood factor analysis was used to provide a structural elucidation of didactic quality and charisma. Pearson correlation coefficients were calculated to investigate possible correlations between the variables. A structural regression model of teacher charisma, student digital affinity, and didactic quality was constructed and a linear regression equation was derived. The tablet-based teaching format was attributed significantly higher values in didactic quality and student satisfaction. The teacher-centred format, on the other hand, performed significantly better in estimated and objective learning gain. Only in tablet-based teaching did teacher charisma correlate with estimated learning gain. Student digital affinity had a stronger effect on didactic quality in this format. In addition, good organization, clear learning objectives, and adequate variation of learning activities were identified as important factors. This study highlights the relevance of teacher charisma and student digital affinity in ensuring high didactic quality in tablet-based teaching. It also shows the importance of congruence of learning objectives, teaching concept, and assessment method of this teaching format to ensure high academic performance. The factors examined should be objectified via specific measuring instruments when designing digital teaching concepts and trained or adapted as necessary to ensure successful integration of digital media in medical teaching.

RetaLac® contains α-lactose monohydrate and hypromellose in the identical proportion. The same parameters were tested in the corresponding physical mixtures of FlowLac® 100 with various types of hypromellose (Metolose® 100 SR, Metolose® 4000 SR, Metolose® 100 000 SR) and compared with the substance RetaLac® . Compressibility was evaluated by means of the energy profile of compression and tensile strength of tablets. Salicylic acid was used as the model active ingredient. Dissolution testing was performed using the method of the rotating basket.

Os livros digitais interativos sao presencas cada vez mais constantes no cotidiano das criancas. Diante desta tendencia, esta dissertacao tem como objetivo analisar a nova forma de apresentacao das historias infantis nos tablets, um suporte midiatico que completa em 2014 quatro anos de existencia. A pesquisa compreende o contexto historico das plataformas de leitura, as origens dos recursos interativos ainda em papel, as funcionalidades presentes nos livros digitais ampliados, tambem conhecidos como enhanced e-books, suas caracteristicas, seu processo de producao, as mudancas provocadas na narrativa e uma analise de tres casos para compreensao mais aprofundada do funcionamento do livro no tablet \"A Menina do Narizinho Arrebitado\", \"Quem Soltou o Pum?\" e \"Dans Mon Reve\". Esta dissertacao oferece um breve panorama dos livros digitais interativos para as criancas, que nao elimina o livro impresso, como se chegou a cogitar no inicio, mas oferece uma nova experiencia de leitura multimidia, sem deixar sua essencia de lado: a de continuar sendo um livro. / The interactive digital books are constantly increasing presence in childrens quotidian. In the face of this trend, this thesis aims to analyze the new way of presenting childrens stories in tablets, a media support that completes in 2014 four years old. The research comprises the historical context of reading platforms; the origins of the interactive features still on paper; the features present in extended digital books, also known as enhanced e-books; its characteristics; production process; the changes induced in the narrative; and an analysis of three cases for further understanding of the functioning of the book in the tablet \"A Menina do Narizinho Arrebitado\", \"Quem Soltou o Pum?\" e \"Dans Mon Reve\". This dissertation provides a brief overview of interactive digital books for children, which does not eliminate the printed book, as it was considered at first, but offers a new multimedia reading experience, without leaving aside their essence: to remain a book.

The purpose of the study is to highlight educators' preferences and attitudes towards tablet in preschool by describing the use of this digital tool in the preschool educational activities. The use of tablet in preschool is in the study looked upon as a phenomenon. The description of the phenomenon is built on the analysis and interpretation of educators' statements about it. The research questions focus on the following aspects: educators' attitudes towards the tablet and its use in pre-school educational activities, the tablet's current area of use, the culture surrounding the use of this digital tool and the educators’ statements about advantages and disadvantages of tablet's use in preschool. The survey’s data collection method is qualitative interviews and the analysis is based on the phenomenological approach. The survey results are discussed related to previous research on children's digital skills at an early age as well as recent research on the tablet and its use in pre-school educational activities. In the final description of the phenomenon it is clear that the educators, who participate in this study, have a generally positive attitude towards using the tablet in preschool. However, according to the interviews, the use of this digital tool seems to be both multifaceted and a complex phenomenon.
