The main purpose of this article is to describe the importance and the challenges of digital health literacy as recognized during the COVID-19 pandemic. First, basic definitions of health literacy and digital health literacy are provided, followed by, and matched against digital competence frameworks, and health literacy skills content and scales. Based on that, a compatibility analysis is provided, against the expectations for satisfactory levels definition for the respective competences and skills. For the approbation of the approach, results received from the participation of computing students at the Sofia University St. Kliment Ohridski in the COVID-19 Health Literacy Survey are used.

Big data challenges different aspects of storing, processing and managing data, as well as analyzing and using data for business purposes. Applying Data Mining methods over Big Data is another challenge because of huge data volumes, variety of information, and the dynamic of the sources. Different applications are made in this area, but their successful usage depends on understanding many specific parameters. In this paper we present several opportunities for using Data Mining techniques provided by the analytical engine of RDBMS Oracle over data stored in Hadoop Distributed File System (HDFS). Some experimental results are given and they are discussed.

In the software industry there are new major technology trends - i.e. Service Oriented Architecture (SOA), Business Process Management (BPM) and Enterprise Architecture - that had already gained enough popularity and adoption to have a stance on their own in the community of practice, but that have not been successfully incorporated into the standard set of software development practices. This creates a window of opportunity for the Software Engineering (SE) researchers to evaluate the inclusion of these new concepts into the existing software development process. This paper introduces the idea of an integrated framework with the aim of supporting the inclusion of SOA, BPM and EA into the Rational Unified Process (RUP). We expect that the current work will support future researchers in finding the proper path to achieve consensus for the inclusion of the mentioned topics into a common framework.
