With their widespread use and their features such as mobility, localization, and personalization, mobile phones offer a great potential for out-of-class learning. Yet, there is scarce research on the use of mobile phones in language learning contexts nor any on using multimedia messages via mobile phones to improve learners&#039 / vocabulary acquisition. The major aim of this study was to investigate the potentials and effectiveness of using mobile phones in foreign language education. In particular, the effects of using multimedia messages via mobile phones for improving language learners&rsquo / acquisition of words were explored. A mixed method approach involving both quantitative and qualitative components was employed in this study. The quantitative part of the study followed a pre-test/post-test quasi-experimental design. The qualitative part of the study included post-study semi-structured interviews with the students, and a questionnaire involving open ended items. The participants of this study were a group of students attending the English Preparatory School of an English-medium university in Turkey. Three different groups were formed in order to investigate the comparative effectiveness of supplementary materials delivered through 3 different means: mobile phones, web pages, and printed. Analyses of the quantitative data showed that using mobile phones had positive effects on students&rsquo / vocabulary learning. The qualitative data collected through the questionnaire and the interviews supported this finding. All participants provided positive feedback about the mobile learning application used in this study.

This thesis will bring up whether responsive navigations is useful and which strategies users might have when they browse on a mobile website. The purpose is to shed some light on the subject of responsive navigations that it is something one need to take a closer look at. It plays an important role when you develop responsive websites. In this thesis there will be a study with experimental elements. The participants are going to test a few types of menus that is available on responsive mobile sites today. The participants in the study will also be part of a short interview after they have completed the study. The result shows that users have different strategies when they are on a mobile website. There were for example some who wanted filters that made it easier to find on the website. It also shows that the websites that are in this study have some problems that you as user come across when you visit the site. In the conclusion you can see that there are a few things you need to consider when one creates a website for mobile phones. There are some theories that indicates that the website needs to be obvious in how you use it. / I det här arbetet kommer det att tas upp hurvida responsiva navigeringar är användbara och vilka strategier användare kan tänkas ha när de surfar på en webbsida i mobilen. Syftet är att belysa ämnet responsiva navigeringar att det är något man behöver titta närmare på då det är en viktig del i att utveckla responsiva webbsidor. I arbetet så kommer det att genomföras en studie med experimentellt inslag där deltagarna ska testa några av de menytyper som finns på responsiva mobilsidor idag. Deltagarna i studien ska även få vara med på en kort intervju efter de har genomfört studien. Resultatet visar på att användare har olika strategier när de är inne på en mobil webbsida. Som till exempel fanns det de som ville ha filterfunktioner som gjorde det lättare att hitta. Det visar även på att de webbsidor som är med i studien har vissa problem som man stöter på som användare när man besöker den. I slutsatsen kan man se att det finns en del att tänka på när man skapar webbsidor för mobiler och att det finns teorier som pekar på att sidan behöver vara tydlig i hur man använder den.

Η Τηλεϊατρική τα τελευταία χρόνια αναπτύσσεται ραγδαία. Η άσκηση και η παροχή ιατρικών υπηρεσιών από απόσταση με τη χρήση της πληροφορικής και των τηλεπικοινωνιακών τεχνολογιών μπορεί να αποβεί σωτήρια για την ανθρώπινη ζωή, κυρίως σε περιπτώσεις απομονωμένων περιοχών (π.χ. νησιά, ορεινά χωριά), όπου η πρόσβαση σε ιατρικές υπηρεσίες είναι χρονοβόρα ή ακόμη και ανέφικτη. Ισχυρές γλώσσες προγραμματισμού, όπως η JavaME, οι οποίες υποστηρίζονται από τα σύγχρονα κινητά τηλέφωνα, δίδουν τη δυνατότητα σχεδιασμού και ανάπτυξης χρήσιμων εφαρμογών Τηλεϊατρικής. Στην παρούσα εργασία θα παρουσιαστεί η τεχνογνωσία που απαιτείται προκειμένου να μετατραπεί το κινητό τηλέφωνο σε μια συσκευή καταγραφής, επεξεργασίας, απεικόνισης και αποστολής του ηλεκτροκαρδιογραφικού σήματος. Tο ηλεκτροκαρδιογραφικό σήμα μετατρέπεται σε ηχητικό, μέσω της διαμόρφωσης εύρους, προκειμένου να αναγνωρισθεί από το κινητό τηλέφωνο και έπειτα μετατρέπεται πάλι σε ηλεκτροκαρδιογραφικό, μέσω της αποδιαμόρφωσης, προκειμένου να απεικονισθεί και να επεξεργαστεί περαιτέρω από το κινητό τηλέφωνο. Τέλος, θα παρουσιαστεί το αντίστοιχο λογισμικό που κατασκευάστηκε ώστε να επιτελεσθούν οι παραπάνω λειτουργίες. / Telemedicine is being rapidly developed. Practice and provision of medical services from distance via the use of information and telecommunication technology can prove lifesaving, especially in cases of isolated places (i.e. islands, mountainous villages), where access to medical services is time-consuming or infeasible. Powerful programming languages, such as JavaME, which are supported by the modern mobile phones, gives the possibility for designing and developing of useful telemedicine applications. In this thesis, it will be presented the know-how that is required in order to transform the mobile phone into a device able to capture, process, display and transmit the electrocardiographic signal. The electrocardiographic signal is transformed into a sound signal, through modulation, with a view to be recognizable by the mobile phone and then it is transformed again into an electrocardiographic signal, through demodulation, with a view to be further processed by the mobile phone. Also, it will be presented the software that has built so as to carry out these functions.

Mobile technologies are the latest technologies in the realm of communication media. They have the potential to flatten the world by making it a place where gender, age, class, race and nationality can no longer hold us back from being heard and being informed. We have learned that these technologies can help to liberate and empower us, and they can lead to a collective cognition as much as they can distract us from what we need to know about the world we live in. In Greece thousands of years ago, a selected number of Greeks had a public space called the Agora to discuss the issues that concerned the public, meaning each and every citizen. They were the first to be able to create the space and place were the word “democracy” could be brought into language; the very word that was used to start a new war in the era of a communication revolution in the 2003 invasion of Iraq. There are still issues that concern the public today such as wars, global warming, homelessness or human rights which are all matters of our collective cognition. However, today in an age of information revolution the public life of people and their collective cognition is being exercised mostly in the virtual spaces of the Internet. Simultaneously, some physical spaces are being abandoned by people. This thesis investigates the possibility of having physical public spaces that are enriched with communication media and not weakened by it. If architects rethink their designs based on a new understanding of the networked society it might be possible to turn this “networked individualism” into a networked collectivism. However, most designed public spaces fail to offer new possibilities that can transform space for the new generation of users. Here, the aim is to understand a new generation of users. Who have they become as a result of new communication media? And how can architects design in a way that responds to this new subject in architecture?

Eksportavimo priemonė turi galimybę įkrauti eksportuotą M3G failą į mobiliąją aplikaciją ir atidaryti ją Java emuliatoriuje – mobiliajame telefone. Eksportavimo priemonė palyginta su kitomis eksportavimo priemonėmis eksportavus skirtingus 3D modelius į M3G formatą bei palyginus gautus rezultatus pagal 3D objektų savybių bei transformacijų atitikimą pradiniam 3D modeliui, eksportavimo priemonės patikimumą bei kitus kriterijus. / In the master thesis the M3G standard for 3D graphics in mobile phones, its compatibility and possibilities of exporting 3D models to M3G format are investigated. Most popular 3D modelling and exporting to M3G format tools are analyzed. Blender was selected as main master thesis modelling tool for possibility to reach 3D model data using Python scripts. An exporting scheme from Blender to M3G format was created and realized using Python and Java programming languages. The exporter works as a plug-in for the Blender modelling tool. It can be accessed in the main Blender menu. The Python programming language in the exporter was used for extracting data from 3D scene and saving it in XML format. The Java programming language was used for reading 3D data from XML file, making hierarchical 3D elements tree, creating 3D elements tree, constructing data arrays and sectors, where 3D data arrays and sectors are kept and exporting data to M3G file. The exporter can load an exported M3G file to mobile application and show it in Java emulator – mobile phone. On the basis of several 3D models, the created exporter was compared to other exporters using the quality of performance, reliability and other criteria.

Mokslininkai akcentuodami teigiamą mobiliųjų telefonų išplitimo aspektą pažymi, kad mobilieji telefonai leidžia sukurti ir palaikyti įvairius socialinius ryšius (Katz, 2006), kurti asmeninį ir grupinį tapatumą ir jų socialinius tinklus (Castells ir kt., 2007), pagerina ryšius tarp bendraamžių, tėvų ir vaikų, suteikiant didesnes galimybes vaikų priežiūrai ir kontrolei (Ling, Heather, 2011). Tačiau paauglių žavėjimasis mobiliaisiais telefonais ir nekontroliuojamas, netinkamas ir intensyvus naudojimasis jais gali sukelti rimtų socialinių problemų: neigiamai paveikti santykius su tėvais, pakeisti tarpasmeninio bendravimo taisykles su bendraamžiais, apriboti tiesioginę socialinę veiklą, neigiamai paveikti paauglių sveikatą ir psichosocialinę gerovę. Tyrimo objektas - paauglių naudojimasis mobiliaisiais telefonais socialinio elgesio kontekste. Tyrimo hipotezė - intensyvesnis naudojimasis mobiliaisiais telefonais paauglystėje lemia retesnius tiesioginius kontaktus su socialinės aplinkos dalyviais. Tyrimo tikslas - išanalizuoti paauglių naudojimosi mobiliaisiais telefonais ypatumus socialinio elgesio kontekste. Tyrimo uždaviniai: 1. Išanalizuoti mokslinę literatūrą, atskleidžiant priklausomybių nuo mobiliųjų telefonų teorinius aspektus paauglystės raidos ypatumų kontekste. 2. Remiantis mokslo literatūros analize, parengti tyrimo instrumentą, leidžiantį nustatyti: - naudojimosi mobiliaisiais telefonais dažnį ir pobūdį. – paauglių naudojimosi mobiliaisiais telefonais dažnio...

They allow to create personal and group identity and their social network (Castells and others, 2007). They improve relations between persons of the same age, parents and children's, give better opportunities to children's supervision and control (Ling, Heather, 2011). However, teenagers fascination in mobile phones is uncontrolled. Wrong and intensive usage of them can cause serious social problems: they make negative relations between children and parents, they can influence and change rules of interpersonal communication with people of the same age, they can restrict direct social activity, can badly influence teenagers health and psychosocial welfare. The object of the investigation – teenagers usage of mobile phones in the context of social behaviour. The hypothesis of investigation – a very intensive usage of mobile phones in adolescence predetermines rarer contacts with members of social environment. The aim of investigation – to analyse teenagers use of mobile phones peculiarities in the context of social behaviour. The goals of investigation: 1. To analyse scientific literature revealing addiction to mobile phones theatrical aspects in the context of teenagers development peculiarities. 2. Basing on the analysis of scientific literature to arrange the investigation instrument, which allows to... [to full text]

Dažniausiai patiriami sveikatos sutrikimai buvo šilumos pojūtis aplink ausį, odos niežėjimas aplink ausį, odos paraudimas bei galvos skausmas. Vertinant naudojimosi įpročių ir sveikatos būklės sąsajas, nustatyta, kad kalbėjimas mobiliuoju telefonu daugiau nei 1 valandą per parą lėmė beveik 2,9 karto, o mobiliojo telefono nešiojimas arti kūno net 6,5 karto didesnę galimybę turėti prastą sveikatą. / The most common experienced health problems are the warmth around the ear, itching of the skin around the ear, skin flushing and headache. Assessing the links between the mobile phone using habits and health status we found that speaking on mobile phone for more than 1 hour per day resulted in almost 2.9 times, and carrying a mobile phone close to the body even 6.5 times higher chance to have poor health.

Αρχικά θα μελετήσουμε κάποιες έννοιες σχετικές με το δίκτυο της κινητής τηλεφωνίας και θα ασχοληθούμε πιο συγκεκριμένα με τα υποσυστήματα που μεταφέρουν τα γραπτά μηνύματα κινητής τηλεφωνίας. Κύριο μέλημά μας όμως αποτελεί η ανάλυση του τρόπου αποθήκευσης των μηνυμάτων σε συσκευές κινητής τηλεφωνίας και πιο συγκεκριμένα σε συσκευές που έχουν εγκατεστημένο το λειτουργικό σύστημα Android. Θα μελετήσουμε το λειτουργικό σύστημα Android και θα δούμε ποια είναι τα σημαντικότερα πλεονεκτήματά του, ώστε ένας χρήστης να επιλέξει το συγκεκριμένο λειτουργικό σύστημα για τη συσκευή του, αλλά και γιατί αποτελεί πλέον κυρίαρχο λειτουργικό σύστημα για την ανάπτυξη μικροεφαρμογών από τους προγραμματιστές. Ως προς το λειτουργικό Android θα αναλύσουμε εκτενέστερα τον τρόπο αποθήκευσης των γραπτών μηνυμάτων και θα δούμε πως το Android δομεί το κείμενο των μηνυμάτων και τις διάφορες πληροφορίες που παρέχονται από το ίδιο το δίκτυο της κινητής τηλεφωνίας. Θα αναλύσουμε τα σύντομα γραπτά μηνύματα κινητής τηλεφωνίας, γνωστά και ως sms, που είναι η υπηρεσία σύμφωνα με την οποία οι χρήστες ανταλλάσσουν αποκλειστικά κείμενο διατυπώνοντας συναισθήματα, σκέψεις, καθώς και σημαντικές πληροφορίες. Οι πληροφορίες αυτές αποθηκεύονται στη συσκευή κάθε χρήστη και κάθε συσκευή αποτελεί το μοναδικό οικιακό αποθηκευτικό μέσο σε όλο το δίκτυο της κινητής τηλεφωνίας. Οι πληροφορίες που αποθηκεύεται στα sms, αποτελεί σύνθετο πρόβλημα ανάλυσης, καθώς απαρτίζεται από ελλιπής προτάσεις, μεικτό περιεχόμενο ελληνικών και greeklish γραμμάτων, καθώς και συντομογραφίες που ακολουθούν ένα προσωπικό τρόπο γραφής κάποιων λέξεων δίχως να ακολουθείται κάποια νόρμα σύνταξης, ορθογραφίας και συλλαβισμού στο κείμενο. Θα δούμε πως μπορούμε με κατάλληλο φιλτράρισμα της πληροφορίας των γραπτών μηνυμάτων να προσεγγίσουμε όσο το δυνατόν περισσότερο την ανθρώπινη λογική γραφής. Θα αναλύσουμε τα φιλτραρισμένα δεδομένα και θα περιγράψουμε πως μπορεί και ο ίδιος ο χρήστης να συμβάλλει σημαντικά στο φιλτράρισμα αυτό αποκλείοντας λέξεις της αρεσκείας του από τα σύνολο των δεδομένων που θα χρησιμοποιηθούν για ευρετηριοποίηση και πως αυτό επηρεάζει σημαντικά την απόδοση της αναζήτησης. Θα επικεντρωθούμε στις πιο διαδεδομένες δομές δεδομένων που χρησιμοποιούνται για ευρετηριοποίηση και θα αναλύσουμε ποια είναι η κατάλληλότερη δομή που πρέπει να χρησιμοποιηθεί στην περίπτωσή μας και πως αυτή τροποποιήθηκε για το σκοπό της μελέτης μας. Θα αναλύσουμε πως η μετατροπή αυτή αποτέλεσε σημαντική εξέλιξη στην απόδοση του ευρετηρίου μας και πως η αναζήτηση με τη χρήση του ανεστραμμένου ευρετηρίου που αναπτύξαμε απογειώνει την ταχύτητα ανάκτησης των δεδομένων των μηνυμάτων. Τέλος, παραθέτουμε την εφαρμογή που αναπτύξαμε με τη χρήση της γλώσσας προγραμματισμού Java για το λειτουργικό σύστημα Android που ενσωματώνει το ανεστραμμένο ευρετήριο που αναπτύξαμε και βοηθά στην αναζήτηση οποιασδήποτε πληροφορίας από τα γραπτά μηνύματα είτε απευθείας από τη βάση των μηνυμάτων του Android είτε χρησιμοποιώντας το ευρετήριο. / In the current thesis an inverted index was designed for Adroid sms messages which is speeding the information retrieval from the sms database.

No. of bitstreams: 1 Ana Graciela Mendes Fernandes da Fonseca Voltolini.pdf: 3241377 bytes, checksum: 25fd43a67cfbf4260a323ff1fff1e3e9 (MD5) Previous issue date: 2016-04-11 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The research considers the propagation of mobile phones and smartphones and the consequences of this fact on possibilities for teaching and learning. Communication apparatus have always been linked to the teaching-learning process. However, with the most intense development, in recent decades, of the Information and Communication Technologies (ICT), this relation has gained new contours. The Internet arises, the evolution of computing machines and, recently, the explosion of mobile devices, providing new products and converged services. In this context, mobile and smartphones have been used and recommended for support and complement of the teaching-learning process: the so-called Mobile Learning. This segment grows due to the rapid expansion and cheapening of these technologies in society. To scientifically verify this relation, a qualitative research was performed, exploratory type, with two projects of mobile learning underway in Brazil, the Palma - Literacy Mother Language Program and School with Cell Phone. So, from the data from the research, we have identified some aspects related to the use of mobile phones and smartphones for the process of teaching and learning that contribute to the understanding of this field still under construction in Brazil. The use of these devices as support for teaching and learning processes in the studied projects is outlined by aspects technology, public and context and new technologies and mobile learning. The device aspect unfolds in dimensions as dissemination, multi-functionality and accessibility support the proposals, still favor characteristics identified as important to the process of teaching and learning nowadays, as mobility and portability. The projects analyzed show potential and appropriate methodology to the context for which they were created and applied. However, the research indicated that while cellphones and smartphones represent the pinnacle of technological convergence and are considered extremely popular and accessible in contemporary society, with concrete possibilities as in the analyzed projects, failed to gain a solid position as a tool for teaching and learning. Such indication is due, according to the research, to lack of: support, practices show extremely dependent on public or private initiative for its extent and continuity; awareness for the use of available technologies, do not consider the device of the students and a plan that that includes, enables and encourages the use of these devices. Moreover, the research also highlights the need for a critical view of the use and function of technology in these processes. / A pesquisa considera a difusão de celulares e smartphones e as consequências deste fato em possibilidades para o ensino-aprendizagem. Aparatos de comunicação sempre estiveram ligados ao processo de ensino-aprendizagem. Entretanto, com o desenvolvimento mais intenso, nas últimas décadas, das Tecnologias de Informação e Comunicação (TIC), essa relação vem ganhando novos contornos. Surge a Internet, a evolução das máquinas computacionais e, recentemente, a explosão dos dispositivos móveis, fornecendo novos produtos e serviços convergentes. Nesse contexto, celulares e smartphones tem sido utilizados e recomendados para apoio e complemento do processo de ensino-aprendizagem: a chamada Aprendizagem Móvel. Esse ramo cresce devido à rápida expansão e barateamento dessas tecnologias na sociedade. Para verificar cientificamente essa relação foi realizada uma pesquisa de natureza qualitativa, do tipo exploratória, com dois projetos de Aprendizagem Móvel em andamento no Brasil, o Palma – Programa de Alfabetização na Língua Materna e o Escola Com Celular – ECC. Assim, a partir dos dados provenientes da pesquisa, identificamos alguns aspectos relacionados ao uso de celulares e smartphones para o processo de ensino-aprendizagem que contribuem na compreensão desse campo ainda em construção no Brasil. O uso desses dispositivos como suporte para processos de ensino-aprendizagem nos projetos estudados é delineado pelos aspectos tecnologia, dispositivo, público e contexto e novas tecnologias e Aprendizagem Móvel. O aspecto dispositivo desdobra-se em dimensões como disseminação, multifuncionalidade e acessibilidade que embasam os projetos, ainda favorece características apontadas como importantes para o processo de ensino-aprendizagem na atualidade, como mobilidade e portabilidade. Os projetos pesquisados demonstram potencial e metodologia adequada aos contextos para os quais foram criados e aplicados. Entretanto, a pesquisa indicou que ao mesmo tempo em que celulares e smartphones representam o ápice da convergência tecnológica e são considerados extremamente populares e acessíveis na sociedade contemporânea, com possibilidades concretas como nos projetos estudados, não conseguiram conquistar uma posição sólida como suporte para o ensino-aprendizagem. Tal indicação se deve, de acordo com o corpus, à carência de alguns fatores, como: fomento, as práticas se mostram extremamente dependentes da iniciativa pública ou privada para sua extensão e continuidade; sensibilização para o uso de tecnologias disponíveis, não consideram o aparelho dos próprios alunos e um planejamento que inclua, capacite e incentive o uso desses dispositivos. Além disso, a pesquisa também destaca a necessidade de uma visão crítica do uso e papel da tecnologia nesses processos.
