Inclusão via TV digital interativa brasileira: um estudo de caso no estado do Maranhão

Este trabalho discorre sobre o processo de implantação da TV digital interativa no Brasil, tendo como estudo de caso o estado do Maranhão e foca as possibilidades de inclusão social e digital em regiões com fragilidades de prestação de serviços públicos como Previdência Social, atendimento médico, bancário e de ensino a distância. Para tanto, aborda políticas públicas que conduziram ao SBTVD Sistema Brasileiro de Televisão Digital no país. O estudo apresenta as discussões na esfera pública e privada com a participação de organizações reconhecidamente qualificadas dentro e fora do país. Mostra também o complexo processo de articulação governamental com entidades da indústria eletroeletrônica e de grupos de telecomunicações privados instalados no Brasil, bem como a resistência de radiodifusores do setor privado em adotar o modelo proposto pelo Decreto 5.820/06 que prevê distribuição e acesso gratuito da população a serviços públicos essenciais por meio da televisão aberta. As consequências refletidas na permanência do atraso e baixo desenvolvimento do estado do Maranhão abrem possibilidades de superação com os novos programas disponibilizados pela Secretaria de Inclusão Digital (SID), do Ministério das Comunicações para responder à enorme demanda que priva regiões do Brasil como o Maranhão de desenvolvimento social e inclusão digital.

Utilizing ICT to prevent loneliness and social isolation of the elderly. A literature review

Ageing of the population is a worldwide phenomenon. Numerous ICT-based solutions have been developed for elderly care but mainly connected to the physiological and nursing aspects in services for the elderly. Social work is a profession that should pay attention to the comprehensive wellbeing and social needs of the elderly. Many people experience loneliness and depression in their old age, either as a result of living alone or due to a lack of close family ties and reduced connections with their culture of origin, which results in an inability to participate actively in community activities (Singh & Misra, 2009). Participation in society would enhance the quality of life. With the development of information technology, the use of technology in social work practice has risen dramatically. The aim of this literature review is to map out the state of the art of knowledge about the usage of ICT in elderly care and to figure out research-based knowledge about the usability of ICT for the prevention of loneliness and social isolation of elderly people. The data for the current research comes from the core collection of the Web of Science and the data searching was performed using Boolean? The searching resulted in 216 published English articles. After going through the topics and abstracts, 34 articles were selected for the data analysis that is based on a multi approach framework. The analysis of the research approach is categorized according to some aspects of using ICT by older adults from the adoption of ICT to the impact of usage, and the social services for them. This literature review focused on the function of communication by excluding the applications that mainly relate to physical nursing. The results show that the so-called ‘digital divide’ still exists, but the older adults have the willingness to learn and utilise ICT in daily life, especially for communication. The data shows that the usage of ICT can prevent the loneliness and social isolation of older adults, and they are eager for technical support in using ICT. The results of data analysis on theoretical frames and concepts show that this research field applies different theoretical frames from various scientific fields, while a social work approach is lacking. However, a synergic frame of applied theories will be suggested from the perspective of social work.

Digital Personal Assistant for Cognitive Cities: A Paper Prototype

This chapter presents an evaluation and initial testing of a meta-application (meta-app) for enhanced communication and improved interaction (e.g., appointment scheduling) between stakeholders (e.g., citizens) in cognitive cities. The underlying theoretical models as well as the paper prototype are presented to ensure the comprehensibility of the user interface. This paper prototype of the meta-app was evaluated through interviews with various experts in different fields (e.g., a strategic consultant, a small and medium-sized enterprises cofounder in the field of online marketing, an IT project leader, and an innovation manager). The results and implications of the evaluation show that the idea behind this meta-app has the potential to improve the living standards of citizens and to lead to a next step in the realization and maturity of the meta-app. The meta-app helps citizens more effectively manage their time and organize their personal schedules and thus allows them to have more leisure time and take full advantage of it to ensure a good work-life balance to enable them to be the most efficient and productive during their working time.

Personal Digital Assistant 2.0 - A Software Prototype for Cognitive Cities

This paper presents a software prototype of a personal digital assistant 2.0. Based on soft computing methods and cognitive computing this mobile application prototype improves calendar and mobility management in cognitive cities. Applying fuzzy cognitive maps and evolutionary algorithms, the prototype represents a next step towards the realization of cognitive cities (i.e., smart cities enhanced with cognition). A user scenario and a test version of the prototype are included for didactical reasons.

Quantifying urban attractiveness from the distribution and density of digital footprints

In the past, sensors networks in cities have been limited to fixed sensors, embedded in particular locations, under centralised control. Today, new applications can leverage wireless devices and use them as sensors to create aggregated information. In this paper, we show that the emerging patterns unveiled through the analysis of large sets of aggregated digital footprints can provide novel insights into how people experience the city and into some of the drivers behind these emerging patterns. We particularly explore the capacity to quantify the evolution of the attractiveness of urban space with a case study of in the area of the New York City Waterfalls, a public art project of four man-made waterfalls rising from the New York Harbor. Methods to study the impact of an event of this nature are traditionally based on the collection of static information such as surveys and ticket-based people counts, which allow to generate estimates about visitors’ presence in specific areas over time. In contrast, our contribution makes use of the dynamic data that visitors generate, such as the density and distribution of aggregate phone calls and photos taken in different areas of interest and over time. Our analysis provides novel ways to quantify the impact of a public event on the distribution of visitors and on the evolution of the attractiveness of the points of interest in proximity. This information has potential uses for local authorities, researchers, as well as service providers such as mobile network operators.

Cancer mortality inequalities in urban areas: a Bayesian small area analysis in Spanish cities

Intra-urban inequalities in mortality have been infrequently analysed in European contexts. The aim of the present study was to analyse patterns of cancer mortality and their relationship with socioeconomic deprivation in small areas in 11 Spanish cities

Relation between temperature and mortality in thirteen Spanish cities

In this study we examined the shape of the association between temperature and mortality in 13 Spanish cities representing a wide range of climatic and socio demographic conditions. The temperature value linked with minimum mortality (MMT) and the slopes before and after the turning point (MMT) were calculated. Most cities showed a V-shaped temperature-mortality relationship. MMTs were generally higher in cities with warmer climates. Cold and heat effects also depended on climate: effects were greater in hotter cities but lesser in cities with higher variability. The effect of heat was greater than the effect of cold. The effect of cold and MMT was, in general, greater for cardio-respiratory mortality than for total mortality, while the effect of heat was, in general, greater among the elderly

Análise da rede de atores na trajetória de implantação de lan houses no Brasil e seu possível papel de agente propiciador de inclusão digital

A Lan House, surgida no Brasil como um meio de entretenimento para os jovens, se tornou, em um curto espaço de tempo, uma febre nas periferias das grandes cidades brasileiras. Essa disseminação se deu, principalmente, após o programa “Computador para Todos” lançado pelo Governo Federal a título de política pública de inclusão digital. Assim, as Lan Houses se constituíram em uma oportunidade de acesso ao computador e à Internet para aqueles que não teriam ingresso à rede se não fosse a existência desse tipo de instituição comercial (CDI, 2010), sendo a segunda principal provedora de acesso público às TIC no país (CETIC, 2010). Diante desse cenário, este estudo se propõe a descrever a trajetória na implantação das Lan Houses no Brasil, sob a ótica da Teoria Ator-Rede, identificando os atores relevantes na formação de uma rede sociotécnica, por meio do método de estudo de caso único realizado no bairro Jardim Catarina, em São Gonçalo. O trabalho apresenta, ainda, o modelo heurístico de inclusão digital para avaliar se este tipo de estabelecimento apresenta fatores relevantes para fomentar a inclusão digital. O resultado desta análise revela que as Lan Houses não são um agente de inclusão digital, apesar de sua relevância para as regiões com menores índices de renda e, por conseguinte, restritas ao uso de computadores e Internet, como o bairro Jardim Catarina.

The new digital revolution: From the consumer Internet to the industrial Internet

The new digital technologies have led to widespread use of cloud computing, recognition of the potential of big data analytics, and significant progress in aspects of the Internet of Things, such as home automation, smart cities and grids and digital manufacturing. In addition to closing gaps in respect of the basic necessities of access and usage, now the conditions must be established for using the new platforms and finding ways to participate actively in the creation of content and even new applications and platforms. This message runs through the three chapters of this book. Chapter I presents the main features of the digital revolution, emphasizing that today’s world economy is a digital economy. Chapter II examines the region’s strengths and weaknesses with respect to digital access and consumption. Chapter III reviews the main policy debates and urges countries to take a more proactive approach towards, for example, regulation, network neutrality and combating cybercrime. The conclusion highlights two crucial elements: first, the need to take steps towards a single regional digital market that can compete in a world of global platforms by tapping the benefits of economies of scale and developing network economies; and second, the significance of the next stage of the digital agenda for Latin America and the Caribbean (eLAC2018), which will embody the latest updates to a cooperation strategy that has been in place for over a decade.

Modelagem paramétrica linear aplicada à faixa de sinal de televisão digital para cidades densamente arborizadas

Este trabalho apresenta uma modelagem paramétrica (auto-regressiva) linear aplicável a estudos de propagação de televisão digital e telefonia celular para cidades densamente arborizadas. A modelagem proposta apresenta um forte embasamento estatístico e depende apenas de dados provenientes de medição, no caso dados relativos a potência recebida e o valor de PSNR (Peak Signal-to-Noise Ratio). Um algoritmo genético é utilizado no cálculo dos parâmetros de ajuste do modelo a um conjunto de dados. O trabalho foi realizado na faixa de televisão digital e foram analisadas duas variáveis: a potência recebida do sinal e o valor de PSNR. Foram executadas campanhas de medição na cidade de Belém. Nestas medições foram coletados dados de potência e gravados vídeos da programação diária de uma emissora de televisão. Os resultados podem ser aplicados no planejamento de serviços de telecomunicações.
