Health Institutions use the EHR (Electronic Health Record) for many years to register the patients’ information electronically. On the other hand, this data is still in many different systems of the health institutions, which the patient interacted over life. During a medical appointment, one does not have a current view of the patient's health history. One of the goals of the PHR (Personal Health Record) concept is to obtain a unified view of the records scattered in various health organizations. Many experts now believe that blockchain technology allows storing a patient's pertinent medical information where needed, allowing both the patient and health care professionals to have access to up-to-date information. However, among the challenges to achieve the goal of an interoperable PHR model is the choice of a blockchain platform that supports the storage of this data in a secure, transparent, and decentralized manner. This article proposes an architecture model for health records based on blockchain. The main outcome is storing part of an electronic medical record in the proposed solution. It aims to process and store medical data, which comes from different health institutions safely inside the blockchain network. Then the EHR data is available to authorized stakeholders in a unique viewpoint through a decentralized blockchain application. After experimenting with two different blockchain frameworks, we decided to implement the prototype in a permissioned blockchain. We created and deployed a business network composed of two different organizations, which stored and shared EHR data among the network participants. Performance tests while retrieving EHR data from the blockchain showed an average response time in milliseconds of 201.08 with 500 users and 15,402.9 with 1000 users. Our proposed solution was able to address the main challenge faced by patients that have EHR data scattered in many distinct locations. The prototype supplies a unique view of this data where the participating organizations accessed the EHR data. However, a more robust hardware setup is necessary to test the blockchain solution in future works. Additionally, our intent is to focus on internal aspects of HIS, especially on how to convert the current EHR data from any health data standard to HL7 FHIR, as this would allow many different health institutions, which are using different data standards to take part in the network.

This paper presents a research project that used eye tracking technology to study optionality within the online transactional process. The focus was on how micro-decisions can be framed: the option type; the impact of decision default values; and the types of decision constructs. It elaborates and improves on a pilot study that was used to test the experiment design. Prior research that identified problematic decision constructs informed the types of decisions studied. The main findings relate to participant task error rates.

Structured data on the Web has become very important over the last few years. Schema.org has proven to be the most recognized vocabulary for structuring data on the Web. However, most annotations using Schema.org's vocabulary describe exclusively content on websites. Today, these structured content data are mainly consumed by search engines to automatically browse websites with high speed and accuracy and to take over search efforts for humans. Annotated web user interfaces can hardly be found on websites or applications. Schema.org’s offered vocabulary to describe actions in a structured way plays a minor role on websites or applications and is mainly applied on rich emails. Also most structured data tools and platforms do not support the annotation of actions triggered via the user interface of a website or application. In this paper we motivate the importance of a semantic description of web user interfaces and present possible application areas to consume these structured data. Thereon, we investigate the suitability of Schema.org for the semantic enrichment of web user interfaces. Since there are hundreds of classes and properties in Schema.org, we present a conceptual model of Schema.org classes and properties suitable to annotate user interfaces of websites or applications. We also show to what extent interactive elements on HTML5 websites or applications can be automatically mapped to these model elements. As a proof of concept we introduce Schemator , our WYSIWYG tool to support the semantic enrichment process of web user interfaces. Schemator is not only a comfortable structured data tool but acts also as a SAAS platform to store and manage structured web interface data separated from the underlying websites and applications.

The study focuses on the sociocultural aspects of urban development. Paper presents the complete deterministic concept of service oriented Sociocultural Information Urban Space (SIUS), considered as a logical development of the intercultural-communicational, technical-resource approaches and social machine concept in order to studying and understanding the features, possibilities, and base information flows of the Smart City sociocultural face. The SIUS idea helps to recognize or improve the data driving city concept because of smart technology use, so that greater range of digital services related to the sociocultural city facets can be provided to different stakeholders. The study includes exploring the interaction of pervasive processes of the urban space, specification of the SIUS architecture and concept. Based on principles and practices of the pervasive approach, the main mechanisms of citizens’ involvement into the active creative development of the SIUS are identified. Moreover, the study discusses two application scenarios which demonstrate how pervasive processes of sustainable development and pervasive self-regulation mechanisms of SIUS can be used in order to consider the factual needs of citizens and decision-making.

Information Communication Technology is identified by Uganda government as a key priority sector that will spur socio-economic transformation in the country. Unfortunately, ICT use for e-participation remains a challenge in Uganda. A pertinent issue with e-participation is e-consultation where citizens are expected to use ICT to access and participate in government programs. Despite government’s efforts to increase ICT use by integrating it into its operations, minimal progress is recorded as e-consultation level remains low resulting in increase in corruption, lack of transparency and accountability. This study presents the prominent role of digital crowdsourcing in improving e-consultation in Uganda to be implemented using the ten-phase digital crowdsourcing implementation process with social media (Facebook) as a digital crowdsourcing tool. Using National Environmental Management Authority Facebook account to make an open call, randomly sampled participants will be availed self-administered, semi-structured, close-ended online questionnaires to identify the challenges and critical success factors for e-consultation. The participants will engage in the digital crowdsourcing process to address the problem of plastic waste pollution, a major eyesore globally. The major research outcome will be a consistent crowdsourcing implementation process that can be used to improve e-consultation in Uganda.

Navigating and performing different tasks on the Web can be frustrating for blind users. This is related to different aspects including a linear nature of navigation through the content, the issues of contemporary web pages not following accessibility guidelines, and limitations of assistive technologies trying to keep pace with a constantly changing web stack of technologies. Web automation tools help users to automate tasks and ease the navigation to a desired content. However, most of existing approaches are based on the web browser and, therefore, have some requirements on the hardware and software used, its performance. Furthermore, they have to take into account complex sequences of DOM events which reflect different changes and states on a web page, such as completion of the content loading or reaction on user actions. These non-trivial conglomerates of events often considerably reduce the robustness of web automation. In this paper we introduce a new approach, FastWrap4A, which can analyse user interactions and transpose the automation from the UI level directly to the level of data-focused interactions with web servers. This approach does not require a browser or an integrated web page rendering engine and can be executed on different devices.
