One of the most well-known requirements in educational settings is the need to know what happens in a course, lesson plan or full academic programme. That is true for any type of education but in particular for Open Education with the multiple dimensions of openness. On the one hand, educators (i.e. teachers, professors, tutors, etc.) and practitioners in Open Education need to reshape the course plan according to the actual features of the learners (e.g., learning styles, motivation, performance, et cetera) and therefore they require real-time analytical information to supervise, assess, adapt and offer feedback to the learners. On the other hand, Open Education offers specific opportunities through online learning using Open Educational Resources (OER) and providing Massive Open Online Courses (MOOCs). The online environments and platforms provide huge amount of data on all activities (a huge Excel sheet, labelled as Big Data). More importantly, Open Education with open teaching and learning is now commonly shaped by a learner- centred approach that pushes the learners to be the driver of their own learning. That is, learners require awareness to self-assess their progress along the course and make decisions for their next steps. In short, Open Education is now an always changing process that requires effective support for the decision making process by the educators and the learners.

Open Education can benefit from Big Data and Learning Analytics used and analysed in the right way as well as Open Education can be the enabler for a broader implementation and acceptance of Big Data and Learning Analytics, again if realized in the correct way. Recent research shows the upcoming relevance of Big Data in Open Education through decision support systems aiming at learners and educators, usually representing the information with information visualization techniques and dashboards. There are a lot of on-going research projects related Learning Analytics and Open Education that are producing interesting results to improve learning quality and to achieve societal impact. In this special issue, we present just a selection of fine papers focused on analytics (Moreno et al.), an intelligent assistant, higher education, vocational education, employment, gamification, augmented reality and Open Educational Resources. We hope that the reader enjoys as much as we did, as editors of this double-blind, peer reviewed compilation.

Spatial and Textural Aspects for Arabic Handwritten Characters Recognition (Morocco), Boulid, et al. purpose was the recognition of handwritten Arabic characters in their isolated form, and had 2.82% error rate.

A Novel Smart Grid State Estimation Method Based on Neural Networks (Egypt) Abdel-Nasseret al. presents a novel method called SE-NN (state estimation using neural network) for smart grid state estimation using artificial neural networks (ANNs) and is a very fast tool to estimate voltages and re/active power loss with a high accuracy compared to the traditional methods.

Conceptual model development of big data (Malaysia) Adrian et al. aims to identify and analyze the affecting factors of BDA implementation and to propose a conceptual model for effective decision-making through BDA implementation assessment.

MSA for Optimal Reconfiguration and capacitor Allocation in Radial/Ring Distribution Networks (Egypt y Japan) Mohamed et al. presents a hybrid heuristic search algorithm called Moth Swarm Algorithm (MSA) in the context of power loss minimization of radial distribution networks (RDN). Results state that MSA can achieve optimal solutions for losses reduction and capacitor locations with finest performance compared with many existing algorithms.

IJIMAI 2018 - Special Issue on Big Data and e-health - Vol. 4 Issue 7

Year: 2018, Vol: 4, Number: 7         application/pdf icon

Data are becoming increasingly important in health management. Just think of the advantages that could derive from monitoring the vital signs of any person and their symptoms turning them into an online platform that, upon proper authorization, doctors could access at any time and from any place. This is just an example of the kind of transformation processes that health management is undergoing.

In this improvement of health services triggered by new technologies, Big Data is playing a prominent role. The benefits derived from Big Data are becoming a reality in health fields as diverse as: medical services, synthesis of data from medical histories and clinical analysis, management of health centers, hospital administration, distribution of material (especially relevant to specific epidemic needs), detection and prevention of possible side effects of drugs and treatments, scientific documentation (generation, storage and exploitation), medical research, fight against cancer or Pandemic prevention.

Big Data allows integrating structured and unstructured data effectively. Where Big Data can bring more value is in the analysis of unstructured data, in which there is more knowledge to be discovered and exploited. In addition to all this, there is data coming from social networks and those generated by the Internet of things; devices, sensors, medical instruments, fitness equipment, ...

But the important thing is not to have a lot of data, but the fact that Big Data tools contribute to the design and implementation of efficient processes that help us carry out health care policies based not only on the available data, but also on their interpretation and understanding. This is how it can effectively contribute to improving health care, saving lives, expanding access to health systems and optimizing costs. In this regard, the important role played by Big Data in genomic research and genome sequencing should be mentioned.

This special issue is designed with the primary objective of showing what we have just pointed out: the diversity of fields where big data is used and consequently, how it is increasingly gaining importance as a tool for analysis and research in the field of healing. In this sense there are papers related to the following topics: re-using electronic health records with artificial intelligence, big data analytics solution for intelligent healthcare management, development of a predictive model for successful induction of labour, big data and the efficient management of outpatient visits, development of injury prevention policies following a big data approach, generating big data sets from knowledge-based decision support systems to pursue value-based healthcare, the use of administrative records of health information both for diagnoses and patients, and an analysis of the European public health system model and the corresponding healthcare and management-related information systems, the challenges that these health systems are currently facing, and the possible contributions of big data solutions to this field.

IJIMAI 2017 - Special Issue on 3D Medicine and Artificial Intelligence - Vol. 4 Issue 5

Year: 2017, Vol: 4, Number: 5         application/pdf icon

Although Medicine has always been considered a Health Science, today it is not possible to obviate its relationship with other disciplines as Humanities and Basic Sciences. Doctors from everywhere and everyday work with the most sophisticated technology are trying to make their profession more accurate and precise, taking in consideration, at the same time, the human part of their daily labour.

In this volume of the Journal, we will try to explore the relation between different medical specialities, basic science and engineering. In fact, modern Medicine requires the participation of these professionals who are involved with doctors in multidisciplinary teams. In this sense, Medical Engineering, is a new degree that is offered in a vast number of Universities along the world.

This relationship between Medicine and Sciences can be found in any medical speciality so that, our aim in this volume, is to show different examples of doctors working together with other scientifics in any area of Medical sciences.

The volume consists on twelve papers. Each paper explores a particular area of this multidisciplinary approach.
