Bakgrund: Många tonåringar lider av sömnbrist på grund av sen eller nattlig användning av smartphones, vilket kan påverka deras hälsa och skolprestationer. Skolsköterskans uppdrag är att arbeta hälsofrämjande. I mötet med tonåringar har skolsköterskan möjlighet att uppmärksamma sömn- och smartphonevanor. Syfte: Att belysa skolsköterskors erfarenheter av och arbete med tonåringars sömn i relation till användning av smartphones. Metod: En kvalitativ metod med induktiv ansats användes. Ett strategiskt urval gjordes. Inklusionskriterier var skolsköterskor med minst 1 års erfarenhet som arbetar med tonåringar. Nio skolsköterskor intervjuades via e-post och datamaterialet analyserades med hjälp av kvalitativ innehållsanalys. Resultat: Analysen resulterade i tre huvudkategorier : Hur smartphones påverkar tonåringars sömn, Att uppmärksamma, informera och motivera, Hälsofrämjande samarbete, och sju underkategorier: Att ha mobilen vid sängen, Konsekvenser i vardagen, Att inhämta kunskap om tonåringars smartphoneanvändning och sömn, Att informera, Att motivera, Samarbete med vårdnadshavare och Samarbete med övrig personal. Konklusion: Skolsköterskors hälsofrämjande arbete gällande sömn i relation till smartphones är beroende av varje enskild skolsköterskas kunskap, engagemang och intresse. Nationella riktlinjer för skolsköterskors arbete med sömn och smartphones samt en omarbetning av hälsoenkäten som används vid hälsosamtalet efterfrågas av skolsköterskorna. / Background: Many teenagers suffer from sleep deprivation due to late or nightly use of smartphones, affecting health and academic performance.

Teknikens snabba utveckling har förändrat hur människor använder teknik och hur vanor bildas kring den. Tidigare forskning visar att majoriteten av smartphoneanvändare ofta använder sin enhet under sociala aktiviteter, även om det inte anses vara socialt accepterat. Detta faktum gör det intressant att undersöka vilka faktorer och funktioner som påverkar användningen av smartphones under sociala aktiviteter samt om det finns några situationer som motiverar till eventuella undantag. I denna undersökning utforskas Medieteknikstudenters ställningstagande vad gäller användningen av smartphones under sociala situationer. De sociala situationerna har begränsats till en grupp bestående av tre till fem vänner i en café- eller restaurangmiljö. För att besvara frågeställningen har en studie genomförts i form av dels en kvantitativ enkät som skickades ut till studenterna, samt en kvalitativ studie i form av fokusgrupper. Resultatet av de båda visade att det inte fanns ett definitivt svar på studenternas inställning till användandet av smartphones i dessa situationer, utan de flesta studenterna ansåg vad som var acceptabelt eller inte var beroende av situationen. Majoriteten tyckte också att användande som inte var märkbar eller användning som bidrog till den sociala situationen var acceptabelt. / Technology’s swift development has changed the way people use it and the way habits form around it. Research has shown that the majority of smartphone users use their device during social activities, even though it is deemed unacceptable. This idea is what makes it interesting to investigate what factors, and if there are applications, that affect the use of smartphones during social activities and if there are any situations that warrants exceptions. The problem this essay will explore is:" What is Media Technology students’ stance on the use of smartphones during social activities?". The social activities were narrowed down to a group consisting of three to five friends in a café or restaurant setting. To answer the problem a quantitative survey was sent out to the target group and qualitative focus groups were conducted. The result of both showed that there was not a definitive answer on the students’ stance. Most students felt that whether something was acceptable or not was contingent on the situation at hand. The majority felt like unnoticeable use or use that contributed to the social activity was acceptable.

This thesis evaluates a hypothesis about how to implement a low cost Differential GPS (DGPS) solution, able to find a current location with a precision almost as good as more expensive DGPS solution.  For this purpose two Smartphone’s are used, one used as a fixed reference station and another used as a roving receiver. The reference station calculates the temporary error at its location at every second and transmits these errors to a server over the internet.  The roving receiver requests to the server to get the latest error from the reference station over the internet. By using these errors or differences, the roving receiver finds a corrected location. The results are in the same range as dedicated DGPS solutions.

Detta arbete avser redogöra om och hur kommuner och kommunala bolag använder sig av mobila GIS-appar i det dagliga arbetet. Det ska även ge en allmän beskrivning av hur teknologin fungerar och hur marknaden ser ut. Som det är just nu ökar användningen av smarta mobiler, så kallade "smartphones", hos allmänheten och även företag har börjat köpa in smartphones till kontoren. Även försäljningen av surfplattor har ökat och förväntas öka ännu mer de närmaste åren. Detta medför att marknaden för applikationer har ökat avsevärt. När det gäller användandet av mobila GIS-appar inom kommuner och kommunala bolag verkar marknaden just nu vara ganska liten men intresset ökar. Av de som svarat på vår enkät svarade en majoritet att de skulle kunna tänka sig att använda mobila GIS-appar och att de var intresserade av att utveckla egna applikationer specialiserade för deras behov. Teknologin utvecklas väldigt snabbt just nu och nya modeller av både smartphones och surfplattor kommer ständigt ut på marknaden. Modellerna blir tåligare och kraftfullare men än så länge är det en bit kvar innan de kommer ikapp den ruggade PC:n när det gäller funktionalitet. Just nu är det inte många av de kommuner och kommunala bolag som svarat på enkäten som använder mobila GIS-appar ofta i sitt dagliga arbete. Detta verkar bero på att informationen om vilka applikationer som finns och hur man använder dem inte når ut till organisationerna. Rädslan för att enheterna som applikationerna används på inte ska klara av fältarbete är också en av anledningarna till att andra metoder väljs. Vad vi kommit fram till efter sammanställningen av enkäten och de två telefonintervjuer som gjorts är att kommunerna och deras kommunala bolag är intresserade av mobila GIS-appar och vill kunna ta till sig tekniken men vet inte hur det ska gå till än. / The intention of this work is to describe whether and how municipalities and municipal companies make use of mobile GIS-apps in their daily work. It will also give a general description of how the technology works and what the market looks like. Right now the use of Smartphones is increasing with the public and even companies have started buying smartphones to their offices. The sale of Tablets has also increased and is expected to increase even more in the next few years. This means that the market for applications have increased considerably. The use of mobile GIS-apps by municipalities and municipal companies seems to be rather small right now but the interest is growing all the time. Of those who responded to our questionnaire the majority said that they would be willing to use mobile GIS-apps and that they were interested in developing their own applications specialized for their needs. The technology is developing very rapidly right now and new models of both smartphones and tablets are constantly on the market. The models are more durable and more powerful but as yet there is some way to go before they catch up with the rugged PC in terms of functionality. Right now not many of the municipalities and municipal companies that have answered our questionnaire are using mobile GIS-apps often in their daily work. This appears to be because the information about what applications are available and how to use them do not reach out to the organizations. The fear that the devices that the applications are used on will not be good enough for fieldwork is also one of the reasons why other methods are chosen. What we have found after compiling the questionnaire and conducted two telephone interviews is that municipalities and municipal corporations are interested in mobile GIS-apps and want to embrace the technology but do not yet know how.

The purpose of this study was to investigate the utility of mobile-assisted language learning (MALL) in Swaziland, mainly the use of smartphones for learning English. Because of the need to enable communicative language practice, and access to authentic content (Chinnery, 2006; Petersen & Divitini, 2004; Sole, Calic, & Neijmann, 2010) the use of MALL is currently the main focus in language learning and technology. Therefore, this study examined the utility of MALL in Swaziland, and students' beliefs about the potential benefits of using MALL for learning English in class. To achieve this goal, the main independent variables in the study were purposes for which students use smartphones out of class for learning English vis-à-vis their beliefs about the potential benefits of using smartphones in class for the same reason. The study also investigated students' reasoning for either believing that smartphones can be beneficial or not beneficial in class. To investigate these constructs, the study used two forms of data collection methods. First, a 23-item Likert scale was used to collect quantitative data, which were analyzed using both descriptive and inferential statistics. Second, telephone interviews were conducted to collect qualitative data, which were analyzed using both inductive analysis and creative synthesis. The results revealed significant differences among the purposes for which students use smartphones out of class for learning English and the potential benefits of using smartphones in class for the same reason. The results have implications for instruction and curriculum development in Swaziland.

Enquanto que na Europa já encontramos avanços nesta área, em Recife os celulares ainda permanecem banidos dos contextos educacionais. Em função disso, esta pesquisa objetivou mapear os usos dos smartphones para aprendizagem, por estudantes de Pedagogia da Universidade Federal de Pernambuco. A partir deste mapeamento pudemos analisar as estratégias de aprendizagem desses estudantes, em variados espaços e tempos, usos e ferramentas, configurando uma aprendizagem móvel centrada na cultura mobilidade no uso das redes sociais para a educação. Nos capítulos teóricos tratamos das relações entre os smartphones, as redes sociais e a educação. Além disso, conceituamos aprendizagem móvel e seus princípios básicos. A metodologia desta pesquisa se baseou no estudo de caso e desenvolveu-se através de um estudo piloto e um estudo final. O estudo piloto utilizou um questionário de apropriação tecnológica para mapeamento de uso e acesso dos alunos a dispositivos móveis e smartphones. No estudo final realizamos entrevistas semiestruturadas, com o intuito de entender qual as estratégias que esses estudantes utilizavam com seus smartphones. Os resultados nos permitiram identificar as ações que esses estudantes utilizaram como estratégias de aprendizagem, enquanto alunos do Ensino Superior em seus smartphones. O uso das redes sociais para fins educativos para as ações de pesquisa acadêmica e troca de informações foram as mais encontradas entre os alunos. As ferramentas que o smartphone possuem facilitaram a leitura e materiais de aula, o registro e estudo posterior, desses aprendizes. O tempo e o espaço que os mesmos utilizaram para estas ações nos smartphones dizem muito sobre os novos espaços e tempos para aprender: não foram os espaços institucionais tradicionais. Dessa forma, concluímos que os smartphones, podem ajudar os estudantes a aprender, respeitando seu ritmo de aprendizagem. A mobilidade que os mesmos proporcionaram também foram essenciais para que os estudantes escolhessem qual as melhores hora e local para estudar e aprender. Assim, os smartphones puderam proporcionar aprendizagem móvel aos estudantes, de acordo com as necessidades de cada um.

Inicialmente eles possuíam um número limitado de funções, voltados apenas para fazer e receber chamadas. Atualmente, contudo, eles se tornaram dispositivos de propósito geral, oferecendo diversos serviços como GPS, e-mail, jogos, vídeos, etc. Além disto, a cada ano cresce o número de sensores integrados ao smartphone. Essa alta quantidade de sensores possibilita que os atuais dispositivos móveis sejam sensíveis ao contexto, ou seja, entendam o contexto do usuário e adaptem-se a diferentes situações. Contudo, a coleta contínua de dados contextuais e associada ao uso exagerado de sensores consome muita energia. E infelizmente as baterias usadas nos smartphones não evoluíram no mesmo ritmo que os demais componentes. Desta forma, surge um novo desafio: Como prover mais serviços e de melhor qualidade sem desperdiçar energia? Por este motivo, diversos artigos sobre o hardware e o software em dispositivos móveis são voltados para desenvolver soluções em eficiência energética, ou seja, reduzir o consumo de energia sem que os dispositivos percam a performance e a qualidade dos serviços oferecidos. Este trabalho de mestrado propõe um método de redução de consumo de energia baseado em contexto para smartphones através da seleção de sensores. O objetivo é entender quais atividades o usuário executa e o ambiente onde ele se encontra para selecionar apenas os sensores mais adequados ao momento. Com isto evita-se o desperdício de energia causado por diversos sensores ativos sem deixar de atender correntamente ao usuário. Em nosso estudo usamos regras de associação para relacionar diferentes características do usuário, como sociabilidade, mobilidade, posição, etc, de modo a inferir todo o contexto do usuário de maneira simples e rápida. Para validar nosso estudo, desenvolvemos um serviço android e realizamos experimentos de energia. O protótipo conseguiu aumentar o tempo de vida das baterias dos smartphones estudados em mais de uma hora. / In the last years we observed a great change in the way how people interact with their cell phones. Initially, these devices had few functionalities, with receiving and making calls being their main purpose. Nowadays, however, they became general purpose devices, offering a diverse range of services, such as GPS location, e-mail, games, etc. Besides, the great amount of sensors embedded in smartphones enable them to be context aware devices, wich means they can understand the user context and adapt their services to diferent situations. However, the continuous acquisition of context data associated with the overuse of sensors causes high energy consumption. Unfortunately these devices depend on the battery and the battery technology used nowadays haven’t evolved in the same rate of the other components, like CPU and memory. Therefore we face a new problem: How can we provide more services with better quality without wasting energy? To answer this question, many papers in mobile devices hardware and software are focused in energy efficient solutions, in other words, how to reduct the energy consumption in mobile devices without losing performance or quality of service. This master thesis develops a new context aware method for energy consumption reduction in smartphones using sensor selection. The main purpose is to understand where the user is and what activity he/she is doing to select only the necessary sensors to each situation. With less sensor usage we can reduce the energy consumption and since these sensors are necessary we can provide better services to the user. We used association rules for relating diferent features, such as sociability, mobility, position, to better understand the whole user context. To validate our method, we developed an Android service and performed some energy experiments. This prototype was capable of increase the battery life-time in more than one hour.

This paper aims to explore and discuss the points found in published research articles addressing cellphone usage and addiction. The articles vary in their emphasis, methods, and conclusions, but all focus in one way or another on how the advent of cellphone usage has caused addiction in many cellphone and smartphone users. Many of these studies involve looking at college students and teenagers to see how addiction and cellphone usage has affected younger generations. The articles at hand include studies from many different parts of the world. Some of the studies focus on which smartphone activities are the most addictive, while some of the articles focus on addiction as a whole and its impact on the users. Many of the works done on this subject focus on how addiction to these devices compares to a traditional substance abuse. While cellphones and smartphones have had many positive impacts, these improvements do not come without psychosocial hazards and addiction potential. Society places a premium on the ability to better communicate and utilize cellphone technology, but do they truly know what costs these benefits come with?
