Análise cefalométrica: ortodontistas x radiologistas

Cephalometric analysis is the mensuration of linear and angular measures through demarcation points as distances and lines on teleradiography, and is considered of fundamental importance for diagnosis and orthodontic planning. In this manner, the objective of this research was to compare cephalometric measurements obtained by dentists and radiologists from the analysis of the same radiograph, in a computerized cephalometric analysis program. All research participants marked 18 cephalometric points on a 14-inch notebook computer, as directed by the program itself (Radiocef 2®). From there, they generated 14 cephalometric parameters including skeletal, dental-skeletal, dental and soft tissue. In order to verify the intra-examiner agreement, 10 professionals from each group repeated the marking of the points with a minimum interval of eight days between the two markings. The intra-group variability was calculated based on the coefficients of variation (CV). The comparison between groups was performed using the Student t-test for normally distributed variables, and using the Mann-Whitney test for those with non-normal distribution. In the group of orthodontists, the measurements of Pog and 1-NB, SL, S-Ls Line, S-Li Line and 1.NB showed high internal variability. In the group of radiologists, the same occurred with the values of Pog and 1-NB, S-Ls Line, S-Li Line and 1.NA. In the comparison between groups, all the analyzed linear values and two angular values showed statistically significant differences between radiologists and dentists (p <0.05). According to the results, the interexaminer error in cephalometric analysis requires more attention, but does not come from a specific class of specialists, being either dentists or radiologists.

Vorwort: Vom Medienprojekt zur nachhaltigen Mediennutzung auf dem Digitalen Campus

Digitale Medien haben sich durch verschiedene Initiativen als ein selbstverständlicher Bestandteil im Hochschulalltag etabliert, wie z.B. bei der Literaturrecherche und -beschaffung, bei der Dokumentbearbeitung und -distribution ebenso wie bei der Präsentation und Kommunikation und im weitesten Sinne: als Medien des Lehrens und Lernens. Die Entwicklung lässt dabei nicht erkennen, dass sich traditionelle Hochschulen auflösen und vermehrt „virtuellen Universitäten“ Platz machen, wie noch vor wenigen Jahren von manchen Enthusiasten vorhergesagt wurde.Mit den zunehmend verfügbaren Erkenntnissen aus einer Vielzahl von Projekten und Aktivitäten an Hochschulen geht es heute vorrangig nicht mehr um die Erprobung „neuer“ Ansätze mediengestützten Lernens, sondern um die (Weiter-) Entwicklung von Strukturen und Prozessen, um bestehende Ansätze auf der Basis solcher Erkenntnisse konsequent zu erweitern und die aufgezeigten Potenziale digitaler Medien in der Lehre gezielt zu nutzen. Zentrale Aufgaben werden die Umsetzung von Konzepten des Medieneinsatzes in der alltäglichen Lehre und deren dauerhafte Integration in den Hochschulalltag, in Studienrichtungen und Studiengänge.Dieser Band gibt einen Einblick in aktuelle Bemühungen an Hochschulen, diese Prozesse der Hochschulentwicklung mit und durch Medien zu gestalten. Er beinhaltet die Vorträge der GMW03 – Conference on Media in Higher Education, der 8. Jahrestagung der Gesellschaft für Medien in der Wissenschaft e.V., die vom 16.-19. September 2003 an der Universität Duisburg-Essen stattgefunden hat. (DIPF/Orig.)

Multimediale, interaktive und patientennahe Lehrszenarien in der medizinischen Ausbildung

MeduMobile ist ein im Rahmen der Ausschreibung „Notebook-University“ vom bmb+f gefördertes Projekt. Ziel des Projektes ist es, die Ausbildung am Krankenbett im Medizinstudium zu verbessern, indem bestimmte Lehrveranstaltungen mit Hilfe von WLAN und Notebook ubiquitär auf dem Campus verfügbar gemacht werden. Hierzu werden neue, so genannte OnCall-Lehrszenarien entwickelt und erprobt, bei denen die auf Abruf bereit stehenden Medizinstudierenden alarmiert und zur Teilnahme gebeten werden, wenn akute und/oder seltene Fälle in die Klinik eingeliefert werden. Die Studierenden nehmen aktiv an den vielfach interdisziplinären Lehrveranstaltungen teil. Der Unterricht findet vor, während und nach der Live-Session statt. Der Hochschullehrer und die Studierenden können den Fall gemeinsam besprechen und die Diagnose bzw. Therapie u.a. an Hand bildgebender Verfahren (CT, Mikroskop, Röntgen, Ultraschall, ...) erarbeiten. Parallel dazu können die Studierenden Lehrmaterialen aus multimedialen Datenbanken, Medline und Internet nutzen sowie eigene Videokonferenzen für die Gruppenarbeit einsetzen. Eine solche Lehrveranstaltung kann somit mehrere didaktische Elemente beinhalten: instruktives, konstruktives, kognitives und kooperatives Lernen. An der Erprobung nehmen etwa 80 Studierende an Veranstaltungen aus 8 Fachgebieten teil. Es werden Studien zur Evaluation des didaktischen Mehrwerts sowie technischer und organisatorischer Qualität durchgeführt. Endgültige Ergebnisse werden Ende 2003 vorliegen.(DIPF/Orig.)

Das Labor im Rucksack – mobile computing in der psychologischen Grundlagenausbildung

Mobile Notebooks, die einen campusweiten Zugriff auf das Hochschulnetzwerk erlauben, eröffnen neue Möglichkeiten der Integration netzbasierter Ressourcen in die reguläre Lehre. Es wird über Entwicklung und gebündelten Einsatz netzbasierter Tools in der psychologischen Grundlagenausbildung berichtet. Spezifische Funktionalitäten mobiler Notebooks wurden in vielfältigen Anwendungen – von Online-Feedback-Instrumenten bis zum virtuellen Experimentallabor – zur Förderung von Lehr-Lern-Prozessen nutzbar gemacht. Sie fördern die individuelle Wissenskonstruktion, indem sie selbstreguliertes und kooperatives Lernen vernetzen, unmittelbares Feedback gewährleisten sowie darüber hinaus die Entwicklung sozialer Bezugsnormen unterstützen. So schaffen sie einen Rahmen, in dem die Studierenden – dem Cognitive Apprenticeship Ansatz folgend – auf ihrem Weg in die wissenschaftliche Community experimentell arbeitender Psychologen von Mitlernenden und Lehrenden unterstützt werden. Innerhalb nur eines Semesters konnten mobile Notebooks und netzbasierte Tools erfolgreich in die reguläre Lehre integriert werden. Die kognitiven und affektiven Grundlagen einer nachhaltigen Verbesserung der Lehr-Lern-Qualität durch den Einsatz derartiger Instrumente werden diskutiert.(DIPF/Orig.)

Project work in a Basque L2 classroom: students’ perceptions

[EN] Project Work has been acknowledged as an efficient medium for language learning for more than two decades (Stoller, 2006) according to the numerous successful applications of project-based programmes that have been reported. In spite of the lack of sufficient controlled studies to assess the benefits of project work, and the existence of some studies giving evidence of students discontent with project work, the reports given by second language (SL) and foreign language students (FL) who have experienced project based instruction give support to the success attributed to project-based learning, as they recognised having improved language skills, learnt content, developed real life skills, as well as gained in self-confidence and motivation (Sierra, 2008 and 2011; Stoller, 2006). The aim of the present study is to explore some key issues involved in implementing a project-based programme focusing on the students’ perceptions of learning gains, their views on the collaborative assessment scheme used in the programme, and the students’ overall evaluations of the implementation of project work in a post-compulsory secondary education context in Navarre, Spain, with students learning Basque as a second language. A group of 12 students enrolled in a project work based programme participated in the study. Results showed that the students’ perceptions were very positive concerning doing projects, learning gains and group work, although more grammar instruction and teacher-fronted activities were requested by the students. However, the collaborative assessment process and the use of a Notebook/Diary as a reflection tool bore mixed evaluations.

The effect of mobile technology as an active student response system on the acquisition of U.S. history content of secondary students with specific learning disabilities

Students with specific learning disabilities (SLD) typically learn less history content than their peers without disabilities and show fewer learning gains. Even when they are provided with the same instructional strategies, many students with SLD struggle to grasp complex historical concepts and content area vocabulary. Many strategies involving technology have been used in the past to enhance learning for students with SLD in history classrooms. However, very few studies have explored the effectiveness of emerging mobile technology in K-12 history classrooms. ^ This study investigated the effects of mobile devices (iPads) as an active student response (ASR) system on the acquisition of U.S. history content of middle school students with SLD. An alternating treatments single subject design was used to compare the effects of two interventions. There were two conditions and a series of pretest probesin this study. The conditions were: (a) direct instruction and studying from handwritten notes using the interactive notebook strategy and (b) direct instruction and studying using the Quizlet App on the iPad. There were three dependent variables in this study: (a) percent correct on tests, (b) rate of correct responses per minute, and (c) rate of errors per minute. ^ A comparative analysis suggested that both interventions (studying from interactive notes and studying using Quizlet on the iPad) had varying degrees of effectiveness in increasing the learning gains of students with SLD. In most cases, both interventions were equally effective. During both interventions, all of the participants increased their percentage correct and increased their rate of correct responses. Most of the participants decreased their rate of errors. ^ The results of this study suggest that teachers of students with SLD should consider a post lesson review in the form of mobile devices as an ASR system or studying from handwritten notes paired with existing evidence-based practices to facilitate students’ knowledge in U.S. history. Future research should focus on the use of other interactive applications on various mobile operating platforms, on other social studies subjects, and should explore various testing formats such as oral question-answer and multiple choice. ^

Wayne McGregor's choreographic language agent

The paper notebook with its companion pencil or pen is a creative tool for many contemporary choreographers and their dancers. Using the notebook affords a relationship with a set of external objects inscribed “on the page” in the form of drawn sketches, notations, and diagrams combined with text (Blackwell et al.). This relationship can be described in cognitive terms, for example, where the page becomes a surrogate for working memory, or a way for seeing something new by modeling structures or processes. The notebook in this sense becomes a site for the encounter of cognition and creativity, providing a place for thinking generatively with external objects (sketches, notations, etc.), an idea this essay will revisit.

Retos en la implementación de las normas internacionales al interior de los estados. estudio de caso: la región del Mekong y el protocolo de Palermo contra la trata de personas. (2007-2014)

El presente estudio de caso tiene como principal objetivo el de analizar la manera como las características sociopolíticas de los Estados del Mekong, específicamente en el caso de Camboya y Myanmar, dificultan la implementación de las normas enunciadas en el Protocolo de las Naciones Unidas para Prevenir, Reprimir y Sancionar la Trata de Personas, Especialmente Mujeres y Niños, también conocido como el Protocolo de Palermo. En este sentido, se parte de las características principales del Protocolo y de la manera como el tráfico de personas se presenta en el Mekong para posteriormente analizar la forma como la corrupción, la impunidad y la desigualdad de género representan retos sociopolíticos que obstruyen la implementación de los mandatos internacionales enmarcados en este instrumento

Era uma vez...As sete casas da infortuna: relação actor - marioneta : Relatório de estágio

O presente relatório tem como objectivo analisar a realidade de uma Companhia de Marionetas em Portugal, Teatro e Marionetas de Mandrágora, incidindo sobre a relação entre o actor, marioneta e meio envolvente (site specific) no contexto de uma prática teatral concreta, a produção do espectáculo Era uma vez ...As Sete Casas da Infortuna, no Castelo de Santa Maria da Feira. Os resultados apurados acompanham os moldes em que se procurou passar de um actor convencional para a especialização de um micromundo teatral onde a aprendizagem foi, fulcral desde o processo de construção até, à manipulação em cena num universo de trabalho particularmente árduo e específico. A minha trajectória no seio da companhia começou pela familiarização e aprendizagem informal da prática das marionetas através da observação directa dos espectáculos e de diferentes projectos da companhia. A formação feita no local de estágio (atelier da Companhia) foi outra das modalidades de formação que acompanhou o meu trajecto ao longo do estágio através da minha colaboração em projectos como Teatro nas Instituições, sempre sob a égide da divisão de tarefas e de alguma autoaprendizagem com a devida supervisão e orientação de artistas especialistas, como o Director Criativo, enVide neFelibata. O laboratório de aprendizagem prosseguiu pela mão da marionetista Clara Ribeiro que orientou a minha formação no sentido de absorver princípios teórico-práticos como o Foco, o Movimento e o Olhar para uma melhor consciencialização do universo do teatro de marionetas e formas animadas. Ainda nessa aprendizagem, a figura de alguns artistas especialistas foi fulcral, nomeadamente a da cenógrafa Marta Fernandes da Silva, que revelou ser de extrema importância ao longo do estágio pois permitiu uma verdadeira intersecção entre as componentes teórica e prática. Dessa forma pude acompanhar todo o processo de criação do Era uma vez ...As Sete Casas da Infortuna, e colaborar na construção das marionetas que iria manipular como actor - marionetista. Relativamente à questão da componente da interpretação no estágio, esta foi assumida pela encenadora - marionetista, Filipa Alexandre que, com a sua orientação, permitiu um enfoque do grupo de trabalho num processo de criação colectiva. Assim, a nível pessoal, fui movido por uma necessidade premente de descodificar o papel do actor na sua relação com a marioneta e o meio envolvente (site specific). ABSTRACT: This study aims to examine the reality of a Puppet Company in Portugal, the Puppet Theater of Mandrágora, focusing on the relationship between actor, puppet and environment (site specific) in the context of an actual theatrical practice, Once upon a time ...Seven houses of infortune, in the Castle of Santa Maria da Feira. The results obtained follow the way in which one seeks to move from one "conventional" actor to the specialization of a micro theater where learning was central from the building process to manipulation on the scene in a universe of work particularly hard and specific. My initial course within the company began with the familiarization and informal learning of the practice of puppetry through direct observation of performances and various projects of the company. The training done at the company (workshop of the Company) was one of the training arrangements that accompanied my way along the training through assistance on projects such as Teatro nas Instituições, always under the auspices of the division of tasks and due self-teaching with appropriate supervision and guidance of expert artists, such as the Creative Director, enVide neFelibata. The learning laboratory continued by the hand of the puppeteer Clara Ribeiro who supervised my training in order to absorb theoretical and practical principles as the Focus, the Movement and the Look for better awareness of the world of puppetry and animated forms. Also at this level, the figure of some specialist artists were central, such as the scenographer Marta Fernandes da Silva, who proved to be extremely important during this training, allowing a true intersection between the theoretical and the practical components. I could experience the surroundings of the creation notebook of Era uma vez ...As Sete Casas da Infortuna, and collaborate in the preparation of puppets that would handle as an actor - puppeteer. As to the question of the interpretation component on training, this was in charge of stage director - puppeteer, and the Artistic Director, Filipa Alexandre, whose instructions allowed a focus of the working group in a process of collective creation. Accordingly, to a personal level, I was urged to decode the role of the actor in relation to the puppet and the environment (site specific).
