Abstract
In a competitive business environment, strongly supported on Information and Communication Technologies (ICT), organizations increasingly need to be prepared to cope with disruptions in their activity and business processes. Business Continuity Management (BCM) encompasses effective planning for the relaunch of business processes in the short term, through the implementation of a Business Continuity Plan (BCP), which constitutes a decisive management factor for the continuity of value creation or guarantee of delivery of goods or services, to safeguard the business survival. This work addresses this issue, supported by a preliminary literature review oriented to identify and relate the common basis of components and activities of the BCM in the normative references, models and libraries of good practices, in order to explore the identification of its gaps in driving an achievable instrument to all organization sizes, considering each component of the BCM, allowing to assess the stage of preparedness, implementation and appraisal of the essential elements, with greater focus on ICT systems, that guide the BCM and the design of a BCP tailored to an organization.

Abstract
Data visualization is key in the Big Data context, enabling different cognitive perspectives over large datasets. These visual perspectives can prompt relevant advantages with regard to healthcare records, because they may contribute to a faster, more understandable, and adequate way to capture patients' health history and overall condition, thus improving healthcare quality. Timelines are well-known visual artifacts that help healthcare professionals to visualize patients' electronic health records (EHR) over a time period. As data stored in EHR tend to quickly grow with each interaction between patient and healthcare system both number and size, traditional linear timelines are can increasingly become more difficult to manage visually, as they often span over different screens. Considering that a holistic analysis is desirable to provide proper and quality health services, data visualization should enable a seamless understanding of patients' health history and overall condition. When dealing with critical episodes - such as an emergency - where time is an important factor, this is even more decisive. Furthermore, traditional timelines do not support multidimensional data representation. This paper presents a new visual model of time-dependent EHR based on radial models. It is capable of simultaneously displaying several data categories that characterize patients' medical history, enabling medical professionals to be aware of different data categories over time in a single display, without the need to scroll between screens.

Abstract
This research addresses the benefits of ISO 9001 to understand the reasons behind its worldwide adoption. By applying principal component analysis to the results of a survey encompassing 526 valid responses (24.4% response rate), a more business-oriented scale than the traditional internal/external type of motivation with three main categories of benefits is proposed: operational improvement benefit (regarded as the most relevant), profitability and, market. The internal benefits related to the operational improvement are the benefits most felt by organizations, highlighting the contribution of ISO 9001 to improve learning processes and knowledge generation. Concerning the organization size, medium-sized organizations attribute greater importance to the market and competitiveness. However, there are no statistical differences in the reporting of benefits felt in operational improvement and profitability. In relation to the year of certifcation, organizations certified before the year 2000 report higher market benefits when compared to those certified later. The investigation of ISO 9001 within Industry 4.0 and digital processes are suggested for future research.

Abstract
Integration of distributed generation in power distribution networks provides many advantages and challenges to electric power system. Among challenges are the increase in levels of short-circuit currents and changes of power flow direction. These characteristics can interfere in the interruption capacity of protection devices, which are responsible for maintaining the integrity of distribution networks. Therefore, it is essential to understand the effects of distributed generation on protection systems to determine strategies that aim to solve the challenges imposed by this technology. The present work, first, proposes the mathematical formulation to coordinate overcurrent relays and fuse links, considering permanent and temporary faults. The solution is obtained through a dedicated genetic algorithm. Subsequently, this solution method is analyzed under different levels of penetration of distributed generators, allowing to identify points most susceptible to loss of coordination.

Abstract
This paper presents ongoing research aiming at the automatic assessment of simple web applications, like those used in introductory web technologies courses. The distinctive feature of the proposed approach is a web interface matching procedure. This matching procedure verifies if the web interface being assessed corresponds to that of a reference application; otherwise, provides detailed feedback on the detected differences. Since web interfaces are event-driven, this matching is instrumental to assess the functionality. After mapping web interface elements from two applications, these can be targeted with events and property changes can be compared. This paper details the proposed matching algorithm and the current state of its implementation. It also discusses future work to embed this approach in a web environment for solving web application exercises with automatic assessment.
