Acompanha: Elaboração de um aplicativo para resolução de testes conceituais e envio das respostas ao professor / Este trabalho partiu do anseio em potencializar o Ensino de Física para estudantes trabalhadores de Ensino Médio noturno em uma escola do Município de Laranjeiras do Sul - Paraná. Observou-se que os estudantes apresentavam dificuldades de aprendizagem em vários tópicos da Física sendo que algumas delas persistiam durante as aulas. Não obstante, percebeu-se que a desmotivação para aprender também tem forte influência no desempenho estudantil, acentuando a evasão e a repetência escolar. Visando contribuir para a alteração desta situação, utilizaram-se as estratégias de ensino Peer Instruction (Mazur, 1997) e Just-in-Time Teaching (Novak et al., 1999) nas atividades escolares, buscando melhorar o ensino e a aprendizagem de Física. Durante as aulas de Física desenvolvidas nesta pesquisa, foi utilizado um aplicativo para smartphones como banco de questões de Física e como instrumento para envio da resposta durante a resolução de problemas em sala. Esta pesquisa objetivou identificar as potencialidades de um processo de Ensino com o Just-in-Time-Teaching e Peer Instruction, mediados pela interação estudante-App-professor, no ensino de Cinemática. A opção metodológica foi pela pesquisa qualitativa, já que almejávamos melhorias no ensino e na aprendizagem. Utilizou-se a Pesquisa-Ação e a Tabla de Invención como instrumentos para coleta e de análise dos dados. Durante o desenvolvimento foram lecionadas 12 aulas de Física no ensino médio, com 22 estudantes em uma turma de Física, em escola de EJA no município de Laranjeiras do Sul-PR. Como produto, foi desenvolvido um aplicativo para smartphone (App), que opera no sistema operacional Android, para ser utilizado nas votações das respostas dos Testes Conceituais durante as aulas. Um notebook e um roteador foram utilizados para estabelecer a rede wireless e a base de dados para o funcionamento do App. Os resultados mostraram que o aplicativo foi bem aceito pelos estudantes, tem potencial para melhorar a concentração nas atividades de resolução de problemas e para realizar o envio das respostas ao professor. O professor pode salvar as respostas dos estudantes no notebook e fazer uma verificação do aproveitamento de cada estudante. As estratégias de ensino Just-in-Time-Teaching e Peer Instruction mostraram-se como potentes ferramentas para estimular os estudantes a buscar conhecimento de forma autônoma, a reduzir receio que tinham das aulas de Física, a estimular a concentração na resolução individual de problemas e promover discussões em grupos na resolução coletiva. Este trabalho é acompanhado de um produto educacional, em um volume anexo. / This work was based on the yearning to enhance the teaching of Physics for night high school working students at a school in the municipality of Laranjeiras do Sul - Paraná. It was observed that the students presented learning difficulties in several topics of Physics and some of them persisted during the classes. Nevertheless, it was perceived that the demotivation to learn also has a strong influence over the student’s performance, accentuating evasion and grade retention. Seeking to contribute to the alteration of this situation, the teaching strategies Peer Instruction (Mazur, 1997) and Just-in-Time Teaching (Novak et al., 1999) were used in school activities, aiming to improve the teaching and learning of Physics. During the Physics classes developed in this research, a smartphone app was used as a bank of Physics questions and as an instrument to send the answers during the resolution of problems inside the class. This research aimed to identify the potentialities of a Teaching process with Just-in-Time-Teaching and Peer Instruction, mediated by the student-App-teacher interaction, in the Kinematics teaching. The methodological option was of a qualitative research, since we wanted improvements in both teaching and learning. The Research-Action and the Tabla de Invención were used as instruments for data collection and analysis. Through the development, 12 physics classes were taught in high school, with 22 students in a Physics class at an YAE school in the municipality of Laranjeiras do Sul. As a product, a smartphone application (App), which operates on the Android operating system, was developed to be used in the voting of Conceptual Testing responses during classes. A laptop and a router were used to establish the wireless network and database for the operation of the App. The results showed that the application was well accepted by students, have the potential to improve concentration in problem-solving activities and to perform sending of answers to the teacher. The teacher can save the students' answers in the laptop and verify each student's performance. Just-in-Time-Teaching and Peer Instruction teaching strategies proved to be powerful tools to stimulate students to seek autonomous knowledge, reduce fear of physics classes, stimulate concentration in individual problem solving and to promote group discussions in group problem solving. This work is accompanied by an educational product, that follows attached.

abstract: Advancements in mobile technologies have significantly enhanced the capabilities of mobile devices to serve as powerful platforms for sensing, processing, and visualization. Surges in the sensing technology and the abundance of data have enabled the use of these portable devices for real-time data analysis and decision-making in digital signal processing (DSP) applications. Most of the current efforts in DSP education focus on building tools to facilitate understanding of the mathematical principles. However, there is a disconnect between real-world data processing problems and the material presented in a DSP course. Sophisticated mobile interfaces and apps can potentially play a crucial role in providing a hands-on-experience with modern DSP applications to students. In this work, a new paradigm of DSP learning is explored by building an interactive easy-to-use health monitoring application for use in DSP courses. This is motivated by the increasing commercial interest in employing mobile phones for real-time health monitoring tasks. The idea is to exploit the computational abilities of the Android platform to build m-Health modules with sensor interfaces. In particular, appropriate sensing modalities have been identified, and a suite of software functionalities have been developed. Within the existing framework of the AJDSP app, a graphical programming environment, interfaces to on-board and external sensor hardware have also been developed to acquire and process physiological data. The set of sensor signals that can be monitored include electrocardiogram (ECG), photoplethysmogram (PPG), accelerometer signal, and galvanic skin response (GSR). The proposed m-Health modules can be used to estimate parameters such as heart rate, oxygen saturation, step count, and heart rate variability. A set of laboratory exercises have been designed to demonstrate the use of these modules in DSP courses. The app was evaluated through several workshops involving graduate and undergraduate students in signal processing majors at Arizona State University. The usefulness of the software modules in enhancing student understanding of signals, sensors and DSP systems were analyzed. Student opinions about the app and the proposed m-health modules evidenced the merits of integrating tools for mobile sensing and processing in a DSP curriculum, and familiarizing students with challenges in modern data-driven applications. / Dissertation/Thesis / M.S.

The Service Worker is a programmable proxy that allows the clients to keep offline parts of websites or even the whole domains, receive push notifications, have back-ground synchronization and other features. All of these features are available to the user without having to install an application - the user only visits a website. The service worker has gained popularity due to being a key component in the Progressive Web Applications (PWAs). PWAs have already proven to drastically increase the number of visits and the duration of browsing for websites such as Forbes [1], Twitter [2], and many others. The Service Worker is a powerful tool, yet it is hard for clients to understand the security implications of it. Therefore, all modern browser install the service workers without asking the client. While this offers many conveniences to the user, this powerful technology introduces new security risks. This thesis takes a closer look at the structure of the service worker and focuses on the vulnerabilities of its components. After the literature analysis and some testing using the demonstrator developed during this project, the vulnerabilities of the service worker components are classified and presented in the form of the vulnerability matrix; the mitigations to the vulnerabilities are then outlined, and the two are summarized in the form of security guidelines.

The purpose of this thesis is to study the level of understanding of e-health applications among users with diabetes in Bulgaria, to find out how they use those applications, and to provide knowledge on what m-health applications provide to people with diabetes, and what they actually need. This research used TAM variables combined with Innovation Diffusion Theory to produce knowledge on technology acceptance. Therefore, the factors of relative advantage, compatibility, complexity, trialability and observability will be used to determine perceived usefulness, perceived ease of use and behavior intention to use a technology. This research was intended to gather information on the use of diabetes self-management mobile apps in a standardized manner. The instrument used for the survey, a questionnaire, aimed to provide information on the use and experience of mobile health apps for managing diabetes. The final online survey was completed by 71 participants, 38 of which were female, 28 were male and 7 were of non-specified gender. The introductory stage of the survey showed that most of the respondents were between the ages of 31 to 40 years old (28.2 %), and that the largest part of the population sample has been diabetic for five years (32.4%). By taking into consideration the results, it can be said that 74.6% of relative advantage correspond to very high perceived usefulness on behalf of the respondents. And a score of 53.5% shows that the people who took part in the survey exhibit high perceived ease of use of the mobile applications.  This concludes that initially upon using diabetes self-management applications, the respondent’s exhibit high behavioral intention to do so and due to that the applications are not defined as complex, they are suitable for constant use.

In this research end user privacy preferences regarding online resources web and mobile applications and websites are investigated and design requirements needed for the development of a privacy focused, privacy enhancing technology tool are identified, as derived from the literature, the crowd source based solution is the most appealing solution so it is fully analyzed according to our research main focus.

A utilizaÃÃo dos recursos hÃdricos em suas mais distintas formas vem acarretando sÃrios impactos negativos para os reservatÃrios, tanto na exploraÃÃo de suas Ãguas quanto na ocupaÃÃo dos seus entornos. A lagoa costeira do Catà està localizada no municÃpio de Aquiraz-CE, caracteriza-se pela elevada beleza cÃnica, pelos atrativos turÃsticos e pela crescente especulaÃÃo imobiliÃria. A ocupaÃÃo indevida das Ãreas de ProteÃÃo Permanente (APPs) vem acarretando uma sÃrie de impactos ambientais negativos para a lagoa. O presente estudo teve por base estudar as alteraÃÃes morfolÃgicas e sedimentolÃgicas associadas aos impactos ambientais da Lagoa do CatÃ, em decorrÃncia do uso e ocupaÃÃo da sua bacia de contribuiÃÃo, verificando as mudanÃas ao longo dos Ãltimos 10 (dez) anos (2003 - 2013). Para tanto, utilizou-se mapeamento de imagens dos anos de 2007 e 2012 para a identificaÃÃo das atividades de uso e ocupaÃÃo da lagoa e de sua bacia de contribuiÃÃo direta, estimativas de contribuiÃÃo de sedimento das diversas atividades econÃmicas e da cobertura do solo e procedimentos de batimetria atual e comparativa ao ano de 2003, caracterizaÃÃo sedimentolÃgica de 49 amostras do fundo lacustre e relacionamento dos dados de contribuiÃÃo de sedimento com a ocupaÃÃo das APPs. Verificou-se que a bacia de contribuiÃÃo da lagoa à uma Ãrea fortemente influenciada pelos fatores naturais, a exemplo do Ãndice pluviomÃtrico da regiÃo e das atividades exercidas no seu entorno. Quanto a comparaÃÃo do relevo submerso atual com o ano de 2003, observou-se a variaÃÃo do nÃvel das profundidades, identificando um decrÃscimo de 2 metros, assim como a pontualizaÃÃo das maiores profundidades na porÃÃo ao norte da lagoa e das menores na dimensÃo mÃdia e nas suas margens, fato explicado pela constante movimentaÃÃo de sedimentos provenientes das mais diversas atividades. Por meio do mapeamento da regiÃo em anos distintos verificou-se o acrÃscimo e decrÃscimo de diversas classes de usos a nÃvel de Ãrea. Para as estimativas de sedimento as principais atividades que contribuem sÃo: Ãrea descampada, Dunas-paleodunas-planÃcie de deflaÃÃo, faixa de praia e Ãrea urbana. Quanto as caracterÃsticas sedimentolÃgicas hà uma predominÃncia da classe arenosa, principalmente de sedimentos finos e em seguida pela fraÃÃo lamosa. O sistema lagunar possui baixa energia ao norte, e de sul à porÃÃo mÃdia da lagoa hà considerÃvel energia. A geoquÃmica para o ambiente indicou valores baixos de carbonato de cÃlcio no geral, com picos em Ãreas com atividades urbanas intensas. Para os Ãndices de matÃria orgÃnica foram encontradas as maiores quantidades na porÃÃo ao sul, regiÃo caracterizada pela forte aÃÃo antrÃpica. Notou-se a supressÃo de grande parte da APP, sendo possÃvel relacionar os pontos com mais contribuiÃÃes de sedimentos e cargas geoquÃmicas em Ãreas desprovidas de vegetaÃÃo peculiar. AlÃm das vulnerabilidades sujeitas ao ambiente, como as ameaÃas de cheias quando em perÃodos chuvosos, assoreamento em diversas porÃÃes dado as atividades urbanas com contribuiÃÃes para os processos erosivos por meio das diversas construÃÃes e aterramentos. / Hydric resources using in it most different ways have been causing serious negative impacts for its depots, not only in its water exploration, but also in its borders occupation. Catà coastal lake is located in the city of Aquiraz, CearÃ, and itâs characterized by elevated scenic beauty, touristic attractives and increasing real estate speculation. The incorrect occupation of the Permanent Protection Areas (PPAs) is causing a series of serious negative impacts to the lake. This research has in its base the study of the morphological alterations in Catà coastal lake in recurrence of its contribution bay using and occupation, and also verifies its environmental support capacity by using its invested sediment cargo, verifying its changes by the last ten years (2003 â 2013), by image mapping of years 2007 and 2012 for identification of using and occupation activities of the lake and its direct contribution bay, sediment contribution estimation of various economical activities and soil covering and actual and comparative bathymetry procedures in the year of 2003, sediment characterization of 49 samples of lacustrine soil, and data relation of sediment contribution and with PPAs occupation. The identified characteristics belong to the bay as a natural factor influenced area, as instanced by the region pluviometric index and the man-made activities by the borders. As for the comparing of the actual submerged relief with the year of 2003, the biggest observed alteration was the deep level with the decreasing of 2 centimeters, as well as the pointing of the deepest areas in the north of the lake, and the smallest in the medium dimension and its borders, fact explained by the constant sediment moving originated from the most different activities. By the region mapping in different years, it was verified the increasing and decreasing of several using classes in an area level. For the sediment estimate, the most contributing activities are: wildness area, deflation-planed-paleaodunic Dunes, Beach Stripe and Urban Area. As for the sediment characteristics, there is a dominance of sandy class, mostly thin sediments, followed by muddy fraction. The estuarine system has low energy by the downstream, and upward at medium portion thereâs a considerable high energy. Geochemistry for the ambient has indicated low calcium carbonate values in general, with peaks in intense urban activities areas. For organic material index, the highest quantities were found by the south portion, a region with strong man-made action. It was noted the suppression of a biggest area of the PPA, being able to determine the points with more sediment contribution and geochemical cargos in areas without peculiar vegetation. Aside the environment vulnerabilities, like the floods in rainy periods, aggradations in different portions caused by urban activities with contributions for erosive process by different buildings and aggradations.

Recuperar as Áreas de Preservação Permanente (APPs) das bacias hidrográficas constitui-se numa necessidade urgente para que a água não venha a tornar-se mais escassa nos próximos anos. Este trabalho buscou, por meio de métodos, estimar o montante de investimento necessário para o repovoamento florestal das áreas de preservação permanente (APPs) da bacia hidrográfica do ribeirão Itaim, no município de Taubaté, SP. Foram utilizadas técnicas de geoprocessamento para a estimativa das APPs da bacia em atendimento ao Código Florestal (Lei 4771/65 e suas alterações). No plano cartográfico, este trabalho teve como base de dados o projeto Una, que por meio de técnicas de geoprocessamento, no programa SPRING, possibilitou o recorte dos mapas de APPs e de Uso e Ocupação do Solo da bacia do Itaim, cujo cruzamento gerou o mapa de áreas a serem reflorestadas na bacia. A quantificação dos custos de reposição florestal foi baseada em valores provenientes de projetos públicos e privados. Os resultados demonstram a necessidade de um investimento anual da ordem de R$ 846.637,80 (oitocentos e quarenta e seis mil seiscentos e trinta e sete reais e oitenta centavos) para o reflorestamento em um prazo de 30 anos. Concluiu-se que o custo para a reposição florestal da bacia hidrográfica do ribeirão Itaim é de aproximadamente R$ 25,6 milhões e que o uso de técnicas de geoprocessamento permite uma estimativa bastante realista das áreas de preservação permanentes a serem reflorestadas, na bacia hidrográfica do ribeirão Itaim, a qual foi estimada em 1947 ha. / Recover Permanent Preservation Areas (APP) of hydrographic basin is an urgent need to ensure that water will not become more scarce in the coming years. This study aimed to estimate the amount of investment needed for the forestation areas of permanent preservation (APP) in the hydrographic basin of ribeirão Itaim in the city of Taubaté, Brazil. Geoprocessing techniques were used to estimate the APPs for the basin, in response to the Forestry Code (Law 4771; 65 and its amendments). On the map, this work was based on data from the project Una, which, through techniques of geoprocessing in the program SPRING, allowed the statements clipping of APP and Use of Soil and occupation on the Itaim basin, whose cross led the map of areas to be reforested in the basin. The quantification of the costs of replacement forest was based on figures from public and private projects. The results demonstrate the need for an annual investment turns around R$ 846637.80 (eight hundred and forty six thousand, six hundred and thirty-seven reais and eighty cents) for reforestation in a period of 30 years. It was concluded that the cost for the basin forest restoration of Ribeirão Itaim is approximately R$ 25.6 million and that the use of techniques for geoprocessing allows a fairly realistic estimate of permanent preservation areas to be reforested in the basin that region, which was estimated in 1947 ha.

It analyses the migratory influences of the Petrobrás work front in two distinct moments: the first one during the Solimões Port construction and the second, during Coari-Manaus gas duct construction. That was intending to understand the backgrounds of the watershed occupation. The watershed was defined as a spatial unity of environmental planning which relates the physical, economical and social aspects. The aim of this study was to characterize the environmental impacts on that watershed and to analyze how the environmental and aquatic legislation are applied on the Permanent Preservation Areas PPA on the urban perimeter. Although Coari Municipality is a small town, with approximately 73,475 in habitants, it already presents relevant impacts concerning the aquatic supplies. The present study showed that the pH of 7 water sampling stations, out of 8, were between 7.06 and 6.63, which represent water contamination, according to the Water Quality Index. That may be related to the fact that 73% of the domestic effluents have no treatment. The majority of the population living on the PPAs has lived there for 1 to 10 years, totalizing 56% of the population in the Espírito Santo watershed. That population living in the PPAs corresponds to two migratory cycles of Petrobrás work front, in 1996 and 2008. Even though the PPAs are legally instituted as natural vulnerable areas, 54% of them were occupied during the last 20 years. The environmental impacts from this occupation have brought prejudices to the resident population and 52% of the most frequent illness is water-borne diseases. The flooding affect about 90% of the watershed population and, each year, the frequency of the river channel overflow has increased. Upon this background, this research uses the watershed as an environmental planning unity that integrates every constructor s agents from those natural risks susceptible areas. / Este trabalho contextualiza os antecedentes de ocupação na bacia hidrográfica do Espírito Santo, localizada no município de Coari no Estado do Amazonas, entre os anos de 1990 a 2010. Analisa, também, as influências do fluxo migratório oriundo das frentes de trabalho da Petrobrás, em dois momentos: na construção do Terminal Solimões e do Gasoduto Coari- Manaus, na perspectiva de entender como esta bacia vem sendo ocupada. Deste modo, a bacia hidrográfica é utilizada como unidade espacial de planejamento ambiental que interrelaciona aspectos físicos, econômicos e sociais. Tendo como objetivos caracterizar os impactos ambientais na bacia e como é aplicada a legislação ambiental e hídrica nas Áreas de Preservação Permanentes APPs, no perímetro urbano da cidade. Apesar da cidade de Coari ser de pequeno porte, com aproximadamente 73.475 habitantes, já apresenta impactos relevantes no que diz respeito aos seus mananciais hídricos. O presente estudo revelou que dos oito pontos de coleta de água, sete estão com pH entre 7,06 e 6,63, que indica, segundo o Índice de Qualidade da Água IQA, grau de contaminação. Tal dado pode estar relacionado ao fato de que 73% do esgotamento sanitário das águas servidas e dos banheiros não possui tratamento. A maioria dos moradores nas APPs reside nestas áreas há 1 a 10 anos, totalizando 56% dos moradores na bacia. Esta população assim localizada corresponde aos dois ciclos, ou fluxos populacionais oriundos das frentes de trabalho da Petrobrás, nos anos de 1996 e 2008. Mesmo que legalmente instruídas como áreas de vulnerabilidade natural, 54% das APPs foram ocupadas nos últimos 20 anos. Estes impactos ambientais já vêm causando prejuízos à população residente nestas áreas, sendo que 52% das doenças mais frequentes estão relacionadas à veiculação hídrica. Os alagamentos afetam aproximadamente 90% dos moradores da bacia, sendo que, a cada ano o transbordamento do canal de drenagem vem ocorrendo com maior frequência. Diante de tais fatos, esta pesquisa usa a bacia hidrográfica como unidade de planejamento ambiental que possam integrar todos os agentes construtores dessas áreas susceptíveis a riscos naturais.

Para isso, a partir dos estudos de Mattos (2002), Jambeiro (2008), Machado (2003) e Barbosa (2007), são apresentados tanto a evolução da TV, quanto as características que fazem da televisão, ainda hoje, o principal veículo de comunicação no Brasil. Após isso, a pesquisa volta-se para as propostas de interatividade da TV aberta, por meio dos aplicativos para outros dispositivos, com destaque para autores como Primo (2003) e Santaella (2010). Com a análise do funcionamento e dos conteúdos do aplicativo para as partidas de futebol exibidas pela TV Globo, a partir da Copa do Mundo de 2014, e também com a da apresentação de dois projetos desenvolvidos pelo grupo de pesquisa Laboratório de Mídia Digital da UFJF, o trabalho busca comparar o que se tem visto como estratégia das grandes produtoras de conteúdo televisivo e em trabalhos que se dedicam a essa temática, feitos em âmbito experimental e acadêmico. / The present work is a study on the Brazilian digital TV, especially regarding its proposals for digital inclusion, through the interactivity with the audience. To do this, from the studies of Mandy (2002), Jambeiro (2008), Machado (2003) and Barbosa (2007), are presented both the evolution of TV as the features that make television, the main vehicle of communication in Brazil still today. After that, the search turns to open TV interactivity proposals through the apps for other devices, especially for authors such as Primo (2003) and Santaella (2010). With the analysis of the functioning and contents of the application to the football matches shown on TV Globo, from the 2014 FIFA World Cup, and also with the presentation of two projects developed by the research group Digital Media Lab of Juiz de Fora Federal University, the work seeks to compare what's seen as a strategy of the major producers of TV content and in jobs that are dedicated to this subject, made in experimental and academic level.

This project proposes a user-focused approach to study the algorithm logic of on-demand apps, using Netflix as a case study. The main research interest is the perception that the user has about the suggestion and recommendation logic of Netflix. In order to gather the information, a walkthrough method on Netflix was applied as well as personal, in-depth think aloud interviews were carried out. The sample consisted on a selection of heavy users, millennials ex-pats living in Singapore and working in the creative industry to get specific insights on their relationship with the algorithm.  To analyze the gathered material, qualitative content analysis was carried out. This kind of study is important within today’s contemporary media environment to have integral approach to users perceptions instead of just analytical figures and numbers. The theoretical context used to enlight some of the conclusions discussed on this research were based on the study of media in everyday life, global cultural industry studies, as well as algorithm culture and the science and technology studies. How algorithms are perceived have major repercussions not only on on-demand apps, technology business models or entertainment industry but also an intense influence on the way people consume content. Re-thinking the user as a co-producer of information and knowledge, considering some of the implications this phenomenon might have on the creative industry and how that affects on our daily life are some of the issues this research elaborated on. It can be said that the selected sample appreciates the suggestion logics and it has multiple functionalities: recommendation, curation, entertainment, companionship and leisure. Netflix Originals are very well validated; being one of the main attractions of the app. Interface, functionality and features are also items that the sample positively highlights. The accuracy perception of the algorithm is good, although low when compared to other countries where the sample used the app. The same applies to the amount of content and titles available, being these last two, issues that Netflix could improve.   This research was conducted for 8 months, from October 2016 to May 2017, for Sodertorn University – Stockholm, Sweden, with the guidance and support of Associate Professor Anne Kaun.
