On 14 March 2020, Spain came to a standstill and the movement of people was restricted with the publication of Royal Decree (RD) 463/2020 and the education sector had to reinvent itself with new rules and procedures. The purpose of this paper is to analyse the impact of the different government regulations and their effect on university teaching planning. Since the approval of RD 555/2020, educational competences were returned to the autonomous communities and each of them implemented different public policies. We will analyse the specific impact on teaching planning and models applied in Catalonia and their development, which vary according to the evolution of the number of COVID-19 infections and which has been marking the political, economic and social agenda since the beginning of the pandemic. The university has moved from teaching in a face-to-face environment to a virtual or semi-virtual or blended learning environment. This change implies a paradigmatic transformation in communication, education, organisation, evaluation and planning, among others. At ESIC Business & Marketing School (ESIC) these pedagogical paradigm shifts have contributed to transform the learning processes in a context of pedagogical innovation.

Research presents an analysis of the most recent literature focused on digital transformation in business with special emphasis on the area of marketing. Within the framework of the changes that characterize the digital revolution in the Information Society, the use of Big Data is presented as the most important challenge and innovation of recent years. The use of massive data, only accessible to the largest companies, is seen as an effective tool for building customer loyalty by using data generated by the customers themselves to predict their behavior as consumers. However, this same use of data also raises ethical questions which should be explored.

The number of melanoma cancer-related death has increased over the last few years due to the new solar habits. Early diagnosis has become the best prevention method. This work presents a melanoma diagnosis architecture based on the collaboration of several multilabel case-based reasoning subsystems called DERMA. The system has to face up several challenges that include data characterization, pattern matching, reliable diagnosis, and self-explanation capabilities. Experiments using subsystems specialized in confocal and dermoscopy images have provided promising results for helping experts to assess melanoma diagnosis.

Some of the real-world problems are represented with just one label but many of today’s issues are currently being defined with multiple labels. This second group is important because multi-label classes provide a more global picture of the problem. From the study of the characteristics of the most influential systems in this area, MlKnn and RAkEL, we can observe that the main drawback of these specific systems is the time required. Therefore, the aim of the current paper is to develop a more efficient system in terms of computation without incurring accuracy loss. To meet this objective we propose MlCBR, a system for multi-label classification based on Case-Based Reasoning. The results obtained highlight the strong performance of our algorithm in comparison with previous benchmark methods in terms of accuracy rates and computational time reduction.

Even though there are many tutoring systems to help students achieve their goals in terms of theoretical knowledge, as yet there is no system to foment the acquisition of the competences which form an integral part of university degree programs. This issue is crucial because the Higher Education System is changing in Europe. New educational models are being created to introduce competences which correspond specifically to degree programs. In this work-in-progress the general framework to develop an Intelligent Tutoring System (ITS) based on competences is presented. The system monitorizes the acquisition of theoretical knowledge and also the assessment of the competences related to the subject and it takes corrective actions when needed to fix a negative evolution of the student. The framework is divided into four main phases based on artificial intelligence techniques: construction, location, prediction and reinforcement. The main feature of the proposed framework is the fact that it promotes the academic development of the student in the future educational context by providing guidance and supervision to ensure the successful acquisition of both theoretical knowledge and the corresponding subject-related competences.

Melanoma is one of the most important cancers to study in our current social context. This kind of cancer has increased its frequency in the last few years and its mortality is around twenty percent if it is not early treated. In order to improve the early diagnosis, the problem characterization using Machine Learning (ML) is crucial to identify melanoma patterns. Therefore we need to organize the data so that we can apply ML on it. This paper presents a detailed characterization based on the most relevant knowledge in melanomas problem and how to relate them to apply Data Mining techniques to aid medical diagnosis in melanoma and improve the research in this field.
