Introduktion: Fysisk aktivitet är viktigt för både psykiskt och fysiskt välbefinnande. Idag är vi allt mer fysisk inaktiva och stillasittande ökar. Fysisk aktivitet minskar risken för bland annat hjärt- och kärlsjukdomar och typ 2-diabetes. För de som har typ 2- diabetes eller graviditetsdiabetes funkar fysisk aktivitet även behandlande. I takt med digitaliseringens framfart ökar hälsoappar. Dessa har potential att främja hälsosamma beteendeförändringar. Syfte: Syftet med studien var att utvärdera vad för faktorer i hälsoappar som gör att vissa hälsoappar är effektiva för att öka fysisk aktivitet hos vuxna individer med risk för typ 2-diabetes, diagnostiserad typ 2- diabetes eller graviditetsdiabetes. Metod: Studien genomfördes som en systematisk litteraturstudie med 12 vetenskapliga artiklar. Studien analyserades genom en tematisk analys. Resultat: Effektiva appar är multifaktoriella, fler faktorer påverkar. Analysen genererades i tre teman; användarupplevelse och engagemang, beteendeteorier och funktioner i hälsoappar. Dessa tre teman är viktiga för att lyckas med beteendeförändring i en hälsoapp. Användarupplevelse och engagemang kan främjas genom regelbunden feedback. Även individanpassade mål kan ge bra effekt på engagemanget för hälsobeteenden. Appdesign som integrerar beteende teorier kan stödja motivation och hjälpa användare att övervinna hinder för fysisk aktivitet. Slutsats: Effektiva hälsoappar är multifaktoriella och kräver integration av funktioner som förbättrar användarupplevelsen, inkorporerar beteendeteorier och anpassas efter målgruppen för att stödja beteendeförändring. Framtida forskning bör fokusera på att utvärdera del ångsiktiga effekterna av digitala hälsointerventioner för att främja hållbara beteendeförändringar över tid. / Introduction: Physical activity is crucial for both physical and mental well-being. Unfortunately, society is becoming increasingly physically inactive, leading to more sedentary lifestyles. Engaging in physical activity reduces the risk of diseases such as cardiovascular conditions and type 2 diabetes. For individuals with type 2 diabetes or gestational diabetes, physical activity can be an important part of treatment. The rise of digitalization has brought about a proliferation of health apps, which have the potential to promote healthy behavior changes. Purpose: The purpose of the study was to evaluate the factors in health apps that make some of them effective in increasing physical activity among adults at risk for type 2 diabetes, diagnosed with type 2 diabetes, or gestational diabetes. Method: The study was conducted as a systematic literature review with 12 scientific articles. The analysis was performed using thematic analysis. Results: Effective health apps are multifactorial, influenced by multiple factors. The analysis generated three themes: user experience and engagement, behavioral theories, and app functionalities. These three themes are crucial for achieving behavior change in a health app. User experience and engagement can be enhanced through regular feedback. Additionally, personalized goals can positively impact engagement in health behaviors. App design that integrates behavioral theories can support motivation and help users overcome barriers to physical activity. Conclusion: Effective health apps are multifactorial and require the integration of features that enhance user experience, incorporate behavior theories, and are tailored to the target audience to support behavior change. Future research should focus on evaluating the long-term effects of digital health interventions to promote sustainable behavior changes over time.

Sugere-se a hipótese de uma Cidade Instantânea identificada no cotidiano em situações condicionadas por tecnologias de comunicação e informação, e especialmente a computação ubíqua, também conhecida como computação pervasiva ou computação ambiente. A investigação aponta para o entendimento de uma Cidade Instantânea que emerge em coletivos sem escala, sem localização e com fronteiras e limites extremamente frágeis, fluidos e temporários. A Cidade Instantânea se infiltra em todas as formas de cidades existentes sem anulá-las; substituí-las. A Cidade Instantânea não tem um objetivo traçado, ela é pura subjetividade que ganha força e presença nas multidões de indivíduos conectados. / We suggest the hypothesis of an Instant City identified in everyday situations conditioned by information and communication technologies, especially the ubiquitous computing, also known as pervasive computing or ambient computing. The research points to the understanding of an Instant City that emerges in collectives without a precise scale or location, with extremely fragile, fluid and temporary boundaries and limits. The Instant City joins and infiltrate in all forms of existing cities without dismiss them; replace them. The Instant City is pure subjectivity that gains strength and presence in the crowds of connected individuals.

This study aimed to understand the relationship between mobile device screen display size (laptops and smartphones) and text segmentation (continuous text, medium text segments, and small text segments) on learning outcomes, cognitive load, and user perception. This quantitative study occurred during the spring semester of 2015. Seven hundred and seventy-one chemistry students from a higher education university completed one of nine treatments in this 3x3 research design. Data collection took place over four class periods. The study revealed that learning outcomes were not affected by the mobile screen display size or orientation, nor was working memory. However, user perception was affected by the screen display size of the device, and results indicated that participants in the sample felt laptop screens were more acceptable for accessing the digital chemistry text than smartphone screens by a small margin. The study also found that neither learning outcomes, nor working memory was affected by the text segmentation viewed. Though user perception was generally not affected by text segmentation, the study found that for perceived ease of use, participants felt medium text segments were easier to learn from than either continuous or small test segments by a small margin. No interaction affects were found between mobile devices and text segmentation. These findings challenge the findings of some earlier studies that laptops may be better for learning than smartphones because of screen size, landscape orientation is better for learning than portrait orientation in small screen mobile devices, and meaningful text segments may be better for learning than non-meaningful, non-segmented, or overly segmented text. The results of this study suggest that customizing the design to the smartphone screen (as opposed to a one-size-fits-all approach) improves learning from smartphones, making them equal to learning from laptops in terms of learning outcomes and cognitive load, and in some cases, user perspective. / text

Along with the smartphone’s increasing popularity around the world, there is an increasing development and popularity of power-hungry applications: applications that take advantage from these resources and may reduce the smartphones autonomy. This fact is known as one of the biggest to be solved when talking about nowadays smartphones. Considering this, many solutions were proposed and approach this topic in different ways. These solutions can be classified in two major groups: software layer solutions and hardware layer solutions. In one hand, the software layer solutions are the ones that try to reduce the smartphone’s energy drain by only changing the software that composes the smartphone. For example, by improving the Wi-Fi interface or managing the running applications of the smartphone. On the other hand, the hardware layer solutions are the ones that try to improve or increase the energy availability of the smartphone changing or improving only the physical components, for example evolving the technology regarding the batteries. This study presents an approach in software layer for this problem: a system for managing the states of the smartphone’s sensors and components, based on the user profile, aiming energy savings. This work consisted of three steps. In the first step the literature research was done and also a research of the existing solutions in the same area. In the second step the mechanism, called MyBatRecommender, composed by the server and client sides, was presented and developed for the Android operational system. In the last step some validation tests were applied aiming to verify the system efficiency. The results show that when applied to a controlled scenario, the MyBatRecommender achieves around thirty-two per cent of energy savings. / Os smartphones atuais são compostos por uma grande gama de sensores e componentes como GPS, Bluetooth e conexão com a Internet através das interfaces de rede Wi-Fi, 3G, entre diversos outros recursos. Junto com a crescente popularização dos smartphones ao redor do mundo está também o crescente desenvolvimento e popularização dos aplicativos que fazem uso desses recursos e tendem a diminuir a autonomia dos smartphones. Esse fato é considerado como um dos maiores problemas a ser superado no contexto de smartphones atualmente. Tendo esse problema em vista, diversas soluções abordam a questão de diferentes maneiras, e podem ser classificados em dois grupos: soluções em nível de software e soluções em nível de hardware. As soluções em nível de software são aquelas que procuram melhorar o consumo de energia dos smartphones apenas com alterações nos softwares que compõe o smartphone. Por exemplo, melhorando a eficiência da interface de rede Wi-Fi, controlando aplicativos que rodam no smartphone, entre outras. Por outro lado, as soluções em nível de hardware procuram melhorar ou ampliar a disponibilidade de energia nos smartphones através dos seus componentes físicos, como por exemplo evoluindo a tecnologia das baterias dos mesmos. Esta dissertação apresenta uma abordagem em nível de software para esse problema através de um sistema de gerenciamento dos estados dos sensores e componentes de um smartphone, baseado no perfil do usuário, visando a economia de energia. Esse estudo consistiu de três etapas. Na primeira etapa foi feito o levantamento bibliográfico e desenvolvida uma pesquisa de soluções existentes na área, identificando possíveis sistemas e aplicativos com a mesma proposição. Na segunda etapa foi elaborado o mecanismo denominado MyBatRecommender, composto pelas partes servidora e cliente, e implementado para o sistema operacional Android. Por fim, na última etapa, foram aplicadas algumas formas de validação no sistema proposto a fim de verificar a sua eficiência. Os resultados obtidos mostram que o sistema implementado, quando aplicado em cenário de testes controlado, apresenta um resultado que traz uma economia de energia de aproximadamente trinta e dois por cento em relação ao uso sem o mecanismo proposto.

This report describes the development of a RESTful web service for mobile applications. The web service makes resources from an existing system called kompetensdatabasen ("the competence database") available. Kompetensdatabasen holds information about the capabilities of consultants and about assignments carried out at the IT consultant business Nethouse AB. The web service was developed according to the principles of REST and ROA (Resource Oriented Architecture) which puts focus on making resources available. The resources are made available through the HTTP protocol and the methods associated with it. This means it was designed to use the same technologies as the world wide web. Following these principles when designing the system has been of great importance. To make sure that the service does not leak information to competing companies or violate the Personal Data Act some kind of solution for securing the service had to be implemented. A model for authentication was produced to make the system accessible only for employees of the company. / Rapporten beskriver utvecklandet av en RESTful web service för mobilapplikationer. Web servicen tillgängliggör resurser från ett befintligt system som kallas kompetensdatabasen. Kompetensdatabasen innehåller information om konsulters kompetenser och de uppdrag som utförts vid IT-konsultföretaget Nethouse AB. Web servicen utvecklades enligt principerna för REST och ROA (Resource Oriented Architecture) vilket innebär ett fokus på att tillgängliggöra resurser. Resurserna görs nåbara genom HTTP-protokollet och dess metoder, det vill säga samma tekniker som används på webben. Stor vikt har lagts på att designa systemet enligt dessa principer. För att servicen inte skulle läcka information till konkurrenter eller bryta mot personuppgiftslagen behövde någon form av säkerhetslösning implementeras. En autentiseringsmodell togs fram för att göra systemet nåbart enbart för anställda vid företaget.
