The thesis presents two wireless technologies widely used in both everyday life and industrial area. Their working principles and utilization methods are explained, as well as devices which use these technologies and the possibilities of future implementation. The focus is on NFC (Near Field Communication) and RFID (Radio Frequency Identification). NFC is latter of the two, and it has become often used for communication and payments. RFID technology is widely used for personal identification and attendance systems, ACS (Access Control System). The thesis takes up the subject of identification from legislative and normative aspects. The RFID and NFC safety breach possibility is thoroughly discussed and analyzed. The practical part elaborates RFID chip copying possibilities using commonly available software and hardware. In the same part, there will be an employee identification access control system draft for a fictional company, considering cost and safety. In the conclusion, there are recommendations, safety advantages and disadvantages of each suggested systems and the technologies themselves.

Gifford Pinchot’s principles of conservation embody the democratic principles of the United States and how those principles remain relevant today. The three central characteristics of Pinchot’s principles of conservation are wise use, avoiding waste, and securing the autonomy of democratic citizens by preventing monopolistic control over our natural resources. Pinchot’s aim place democratic aspirations at the fore. A case study of the environmental degradation revealed throughout the life-cycle of the cellular phone exhibits how Pinchot’s principles are not only relevant, but sorely needed today. Furthermore, this case study also reveals how globalized corporatism has become the antithesis of the democratic aims of the global citizenry. Pinchot’s principles advise us to check the global monopolies of multinational corporations and greed for greed’s sake to secure a democratic future for the most people, in perpetuity. Though his principles are often neglected, they are more relevant now than ever.

De um lado professores, coordenadores e di-retores, muitas vezes despreparados para lidar com a avalanche tecnológica que sufoca o processo ensino-aprendizagem. Do outro, alunos cada vez mais conectados e deslum-brados com seus smartphones que disponibilizam inúmeras oportunidades de acesso à informação e à comunicação. Esta pesquisa busca discutir e vivenciar este embate atra-vés de uma sequência didática estruturada para utilização do smartphone em sala de aula, visando a aprendizagem significativa de conteúdos da Física. Para tanto, estrutu-ramos um aplicativo utilizando a plataforma MIT App Inventor, onde abordamos os conteúdos da eletrodinâmica. A elaboração dos instrumentos anteriores foi embasada por dados levantados através da aplicação de questionários, sendo que estes, tiveram como referencial teórico a Aprendizagem Significativa de David Ausubel. / Digital information and communication technologies has been the subject of much con-troversy in the school environment in recent years. On the one hand teachers, coordina-tors and directors, often unprepared to deal with the technological avalanche smothers the teaching-learning process. On the other, students increasingly connected and daz-zled with their smartphones that provide numerous opportunities for access to infor-mation and communication. This research aims to discuss and experience this clash through a structured instructional sequence to use the phone in the classroom with a view to significant learning of physics content. Therefore, we designed an application using the MIT App Inventor platform where we discuss contents of electrodynamics. The preparation of previous instruments was based on data collected through question-naires, and these as theoretical reference the Meaningful Learning of David Ausubel.

Utvecklingen av mobiltelefoner och mobiltelefonmarknaden ökar i snabb takt. Bara i Sverigesåldes ca 3.8 miljoner mobiltelefoner år 2011, över hälften av dessa var smartphones.Användning av en ny teknisk enhet kan i många fall vara problematisk till en början och olikastandarder kan utvecklas. Därför frågar vi oss hur lätt det är att byta mellan idag ledandesystem; hur användarvänliga är de för nya användare av andra system? Med hjälp avanvändartester testar vi systemen Android och iOS. Vi lyfter fram områden där systemenvisar brister samt lämnar förbättringsförslag, samt diskuterar om områden där det enasystemet gjort en lösning på ett mer välfungerade sätt. Datainsamlingen skedde genom attgöra användartester på våra testobjekt, HTC one X samt iPhone 4, en testperson i taget ochsammanlagt åtta personer. Testpersonerna fick en enkät med uppgifter att utföra påtestobjektet, denna uppgift fick sedan en svårighetsgradering samt om möjligt en kommentarav testpersonerna. Testerna resulterade i olika problem hos testobjekten, men det slutgiltigaresultatet visade i en hög användbarhet i båda fallen. Vi ser möjligheter till att förbättra bådasystemen men inom olika områden. / The evolution of mobile phones and mobile phone market is growing rapidly. Sweden alonesold approximately 3.8 million mobile phones in 2011, over half of which were smartphones.The use of a new technological device can often be problematic to begin with and differentstandards can developed. Therefore, we ask ourselves how easy it is to switch betweentoday's leading systems; how user-friendly are them for the new users of other systems?With the help of user testing, we test the systems Android 4 and iOS 6. We highlight areaswhere systems show deficiencies and provide suggestions for improvement; we also discussareas where one system has a solution to a more well-functioning manner. Data collectionwas done by usability testing on our test devices, the HTC one X and the iPhone 4, one testperson at a time and a total of eight people. The subjects were given a questionnaire withinformation to perform on the test object, this task were then given a difficulty rating and, ifpossible, a comment of the test subjects. The tests resulted in various problems of the testobjects , but the final result showed a high level of usability in both cases. We seeopportunities to improve both systems but in different areas.

Class of 2012 Abstract / Specific Aims: To assess the use of PDA/smartphone based electronic drug databases among pharmacists as it has changed over time. The working hypothesis is that the use of PDA/Smartphone based electronic drug databases has increased over time. Methods: A systematic review of the literature regarding the usage of PDA/smartphone based electronic drug databases among pharmacists using data that was obtained through literature searches. Main Results: Since 2006, the percentage of pharmacists that are using PDA/smartphone based electronic drug databases has increased. Conclusions: The usage of smartphones and PDA based electronic drug databases has increased among pharmacists since 2006 (p<0.05). Easier and cheaper access to the technology has likely led to the products being available to more pharmacists.

Background Active Learning using smartphone technology can be implemented as a tool for teaching medical students (MS) and residents (Rs). The use of technology would increase participation and enhance student learning by engaging them in solving ID clinical case scenarios. Our objective was to describe the methods used and to share the opinions of the users of such active learning methods. Methods The smartphone applications used were Socrative and WhatsApp. We used Socrative during the Universidad Peruana de Ciencias Aplicadas (UPC) ID course for MS in two different ways. In selected lectures (4 of 32), teacher paced questions were asked based on clinical scenarios related to the topic reviewed, and by voluntary homework questionnaires (student paced). At the British American Hospital (BAH) Medicine Department (MS and Rs) Socrative was used similarly: during some noon lectures (teacher paced questions) and during the baseline MS exam and Rs mid-year exam and voluntary homework questions (student paced). WhatsApp is currently used at the BAH with questions send from Monday to Friday. MS /Rs answer individually via WhatsApp to the mentor in charge. The right answer is given the next day. Questions using WhatsApp deal with recent cases seen at the Wards or in the outpatient clinic, and are designed so that the MS/Rs must do quick literature searches in order to provide the right answer. Results Forty-one MS/Rs answered the survey on Socrative use, 25 of 48 (52%) of UPC MS and 16 (89%) MS/Rs from the BAH. Forty (97%) believed using Socrative had influenced their learning and all but 2 believed it promoted participation from the class. 36 (87.8%) would like to have Socrative used in other lectures and 35 (85%) in other courses. Only one person voted against Socrative use in courses or lectures. With regards to WhatsApp use 16 MS/Rs from BAH answered the survey. Six had used before WhatsApp as a teaching tool. All felt the methodology was useful for learning and promoting reading and would recommend this methodology to promote learning on a student paced way. Conclusion Socrative and WhatsApp can be used for teaching ID through MS/Rs smartphones. Most MS/Rs who were surveyed recommended the use of such methods in their education.

Modern smartphones contain multiple sensors and long lasting batteries, making them ideal platforms for mobility monitoring. Mobility monitoring can provide rehabilitation professionals with an objective portrait of a patient’s daily mobility habits outside of a clinical setting. The objective of this thesis was to improve the performance of the human activity recognition within a custom Wearable Mobility Measurement System (WMMS). Performance of a current WMMS was evaluated on able-bodied and stroke participants to identify areas in need of improvement and differences between populations. Signal features for the waist-worn smartphone WMMS were selected using classifier-independent methods to identify features that were useful across populations. The newly selected features and a transition state recognition method were then implemented before evaluating the improved WMMS system’s activity recognition performance. This thesis demonstrated: 1) diverse population data is important for WMMS system design; 2) certain signal features are useful for human activity recognition across diverse populations; 3) the use of carefully selected features and transition state identification can provide accurate human activity recognition results without computationally complex methods.

Den givna studien undersökte experimentellt om att sova med sin mobiltelefon utanför sovrummet påverkar sömnkvaliteten, jämfört med mobiltelefonen bredvid sängen. Sömnkvalitet mättes genom total sömntid per natt samt en variabel för självskattad sömnkvalitet. Testdeltagarna sov fem vardagar i sträck med sin mobiltelefon bredvid sängen samt fem vardagar i sträck med mobiltelefonen utanför sovrummet och fyllde i data i en sömndagbok dagligen. Resultatet visade att testdeltagarna signifikant sov kortare tid - 21 minuter per natt - när de hade mobilen bredvid sängen. Vidare undersöktes deltagarnas nomofobigrad och hur denna eventuellt influerade resultatet av experimentet, men ingen signifikans fanns. Urvalet var ett bekvämlighetsurval N=25, 13 män och 12 kvinnor, i åldrarna 18–29 (n=14), 30–39 (n=8), 40–49 (n=1) och 50–59 (n=2). Data samlades in genom nomophobia questionnaire och the consensus sleep diary. / The present study experimentally investigated how one’s smartphone’s placement might affect sleep quality. Sleep quality was measured as the variables total sleep time and self-reported sleep quality. The participants slept five consecutive days with their phone by the bed and five consecutive days with their phone outside of their bedroom and filled in data in a sleep diary daily. The results showed that sleeping with the phone by the bed significantly decreased total time slept by 21 minutes per night. Further the study investigated if the participants’ nomophobia score influenced how much they were affected by the study; none of the variables showed significant results. The participants N=25, 13 male and 12 females, were recruited as a convenience selection and covered the ages 18–29 (n=14), 30–39 (n=8), 40–49 (n=1) and 50–59 (n=2). The data was collected using nomophobia questionnaire and the consensus sleep diary.
