After reviewing existing methodologies, it was noted that some key aspects were under-utilized, including user participation and “real interaction” (i.e. monitoring of user interaction with a prototype site). This situation can lead to deficiencies in the resulting website and hence user frustration. A study was carried out to examine various methodologies, from different disciplines, and their integration, to select the strongest aspects of the various methodologies to be combined into a new methodology. This methodology was assessed by interviews and a questionnaire. Proposed further research will develop a website describing the new methodology; incorporate a software tool to assist in tailoring the methodology to a particular project.

Component-driven architectures also appear as an option for creating modern web and mobile applications. Dozens of frameworks appear each day, but they put a focus on the UIs, leaving the content in behind, therefore are not suitable for developing dynamic content-intensive applications. To address this challenge, in this paper we propose an architecture based on React framework, which provides cross-platform solution for dynamic applications that are manageable by external CMS systems. A prototype project is implemented, showing the benefits of the proposed architecture.

Serverless computing is one example of such an emerging paradigm, enabling faster development, more efficient resource usage, as well as no requirements for infrastructure management by end users. Recently, efforts have been made to utilize serverless computing at the network edge, primarily focusing on supporting Internet of Things (IoT) workloads. This study explores open issues, outlines current progress, and summarizes existing research findings about serverless edge computing for IoT by analyzing 67 relevant papers published between 01.01.2015 and 01.09.2021. We discuss the state-of-the-art research in 8 subject areas relevant to the use of serverless at the network edge, derived through the analysis of the selected articles. Results show that even though there is a noticeable interest for this topic, further work is needed to adapt serverless to the resource constrained environment of the edge.

By introducing the concept of e-readiness, which summarizes a broad set of characteristics of a given country, we were able to analyze the factors that drive the adoption of an innovative solution in a market. Our findings suggest that both environmental and firm level factors play an important role in the adoption of an innovative e-commerce solution.

From another point of view, there is a critical shortage of care staff, both in hospitals and for in-home care. Thanks to new technology trends such as Smart Homes and Smart Furniture, there is an opportunity for increased support for seniors by utilizing new technologies. This paper presents the current trends and possibilities in applying smart information and communications technology (ICT) solutions for in-home care concerning diseases in old age. The paper consists of a systematic review according to the PRISMA methodology of the available literature in Web of Science, IEEE Xplore, PubMed, Springer, and the Espacenet patent database. Publications report the usage of some types of artificial intelligence and their implementation and non-intrusive sensing technologies. The patents review identified solutions with a focus on monitoring the state of older adults and mobility improvement. Existing ICT smart solutions must address the following issues: (1) ease-of-use; (2) invisibility and disuse that isolate older adults; (3) privacy and security; (4) affordability of technology in terms of cost; and (5) supporting elderly individuals to stay in their homes or move in different environments independently. There is a significant gap between a large number of scientific publications and commercial solutions. The existing products reflect the specifics of the diseases in a rather wider context instead of the fulfilment of exact needs. It is often stated that such devices can be used across diseases, but the direct connection and benefits for the disease is still rather weak. The challenge remains to tap the existing potential of a large number of innovative ideas on the market and improve the quality of life.

The question raised is to what extent the central government institutions (CGIs) understand the functions and roles of ICT and how they should be utilized for both strengthening the public administration institution they represent and for building relationship with stakeholders and citizens, which will allow the emergence of the second generation of e-participation. This paper analyses the status and provides an initial assessment of eGovernment implementation at central level in the context of usage of social media (SM). The insights emerging from the review of 28 CGIs show a gradually increased use of social networking tools and indicate several differences and similarities in the use of Web 2.0 between different CGIs. Implications and importance of findings are discussed.

In this paper we propose a cloud-based system for recognition of complex activities by detecting series of atomic actions with non-invasive sensors. Collected data from non-invasive, non-intrusive and privacy preserving sensors is streamed into a cloud-based system, where automated feature extraction and activity recognition is performed. The prototype of the proposed system is evaluated with an experiment. Five activities performed by a person in a room were monitored by a sensor kit and streamed to the cloud, where the built classification models could recognize the activities with accuracy of 80% to 95%, depending on the length of segmentation windows which varied from 5 to 20 seconds, respectively.

Electronic health records are integrated with remote patient monitoring systems using various sensors. However, these ecosystems raise many privacy and security concerns. This paper analyzes and proposes a fog-based solution to address privacy and security challenges in connected health. Privacy protection is investigated for two types of data: less invasive sensors, such as sleep monitor; and highly invasive sensors, such as microphones. In this paper, we show how adding computing resources in the edge can improve privacy and data security, while reducing the computational and bandwidth cost in the cloud.

The threat became bigger with the use of social networks like Facebook and Twitter by the students, as a result of that these sites became forbidden in the schools. But when the students are already there, available in any time and place, why can't we try to direct these users for the benefits of innovative learning and to improve their motivation? The following text will try to investigate the possible answers of this question concerning the benefits from using Facebook and twitter in education as a media for communication between students and teacher. After reviewing the subject of research from the aspect of planned distance education or distance learning which will continue and after the end of the school year, desired data will be obtained. Using the WebQuest method will provide approach to learning from the source of the information distant from the students. Qualitative and quantitative indicators will be presented by the measurement of the achievements and by the students and teacher attitudes.

Quality, privacy, and safety, major elements of Connected Health, were evident policy concerns in the Connected Health context. Attention is paid as to how the healthcare systems are evaluated. Evaluation methods and responsibilities range from macro state-level evaluation to more dispersed local evaluation. The constant evolution of European healthcare is reflected in the changing methods of evaluation in countries such as Norway, Greece, Malta, and Serbia.
The vast majority (almost 80%) of respondent countries have eHealth strategies in place or are working on implementing such strategies. In general, e-prescribing and Electronic Health Records are the most common forms of Connected Health activities throughout Europe. There is a clear distinction between patient and consultant usages of these forms of Connected Health. A major issue, especially with the creation of Electronic Health Records, has been ensuring that they are safe and secure and that privacy is attainable. Health Insurance companies also make use of electronic patient records for the storage of and quick access to patient records.
Privacy is recognised as an important factor in the development of accessible patient databases. While two thirds of respondent countries rely on national data protection legislation to protect such databases, others have been more proactive and generated eHealth-specific legislation. Croatia, Germany, Slovenia, the UK, and Macedonia have all begun to recognise the need to draw up legislation which prioritises the protection of patient information recorded through these types of technologies. Public statements and political instruments directly address the topic of Connected Health, helping to protect patients while increasing their awareness of the Connected Health options. Websites and manifestos dedicated to health related activities in various countries are at the centre of this public awareness. Additionally, political parties in some of the respondent countries identify eHealth and Connected Health as an area for improvement in their own manifestos.
Of the nineteen respondents to the survey, fifteen countries contributed specific information on university based programmes that help to ensure that healthcare professionals are aware of and in a position to utilise Connected Health. While few of the programmes focus solely on Connected Health, its inclusion in health and biomedical informatics courses ensures that it will be a part of these future healthcare providers’ understanding of the provision of healthcare. Awareness of Connected Health and the development of health literacy is not solely a concern at third level. Health literacy is a challenge across Europe as a whole. Ad hoc health literacy programmes have been proven to work in some countries, but the public’s infrequent exposure to these forms of literacy, such as television and poster campaigns, means that their benefit is often not fully felt in the long term. The role that Connected Health can play in the improving health literacy does not seem to have been realised, with most countries still relying on leaflets and information booklets to improve patients’ understanding of medical and health related issues. For those countries who actively and regularly promote health literacy, this is done through school systems and specific research communities.
Presenting the business and health models of the healthcare systems in each of the ENJECT respondent’s countries helps to develop an understanding of the level of priority placed upon Connected Health. The majority of European healthcare systems are organised through cooperation between private and public bodies. Their funding and finances primarily come from the public sector, with revenue created through direct and indirect taxes. eHealth models within these healthcare systems’ business models vary significantly across the region and are gradually becoming an accepted part of a healthcare system’s general business models.
To attain an understanding of its healthcare model and patient care pathways, each country has provided a case study of common illnesses. The difference in each country’s method of treatment of the same illness shows how each of the systems operate, with a clear focus on the funding of the treatment in each of the instances.
eHealth Records and digital prescriptions top the list of technically integrated systems at national and
regional levels enabling electronic systems to work across a variety of healthcare contexts. The unification of language and classification systems emerged as a major issue when considering the interoperability of eHealth.
Generally, the level of patient involvement in the design, delivery, and development of health related research programmes is on the increase. With 30% of the respondent countries having a system in place which encourages the inclusion of patients in the design and development of healthcare, this can be seen as a clear starting point for creating even more connected healthcare systems throughout Europe.
In summary, confusion abounds in the area of Connected Health – around wording, application, models, and systems. It involves a complete transformation of the healthcare system in a long-term play that requires dedicated resources and political will. Many of these elements are difficult to capture with data points being largely qualitative and non-comparable. Different countries are at different stages of readiness in terms of Connected Health – both in terms of its research and its implementation. The evaluation criteria employed in different circumstances and different geographies across Europe are neither clear nor standardised. The majority of states and regions are so engaged in the process of ensuring interoperability at a regional or national level that they have little time or attention left to focus on the thorny issue of international interoperability.
We recommend an agenda for future research in Connected Health for Europe that creates a shared language around health records and a database that would facilitate the development of a Connected Health or eHealth scorecard. We would support a common evaluation framework for Connected Health implementations that is multi-faceted, ranging from technology robustness to regulatory compliance, from economic sustainability to user acceptance, and including both qualitative and quantitative measures. There is evident confusion as to the application of existing rights in the context of Connected Health. We recommend an approach specific to eHealth that helps citizens, researchers, companies, and healthcare providers to understand how we live safely and privately in an era of healthcare data. We suggest that studying how some of the ENJECT countries have done this and distilling learnings and best practice from their experience could help to better design future guidelines and interpretations.
