For any organization, it is vital to obtain value from anything it can and having huge amounts of data, Big Data,_pushes them to do so. But only having Big Data is not enough. The most important thing is to use it smartly in order to gain valuable decision support. Making sense of Big Data would happen when we are able to use all the data we have and get important hints and directions. The impediment in the Big Data concept is to obtain support as fast it can be obtained, in real time if possible and the solution used needs to be very malleable because of information technology evolution. Because of this evolution and because of the ease in managing data with Elastic Stack we chose to use Elastic Stack to manage Big Data. The process of making sense of Big Data is based on three big steps: collect, process and use. In order to do so and to make sense of all of this, this paper proposes to use an Elastic Stack solution, also known as ELK (Elasticsearch, Logstash and Kibana), to easily and rapidly manage the Big Data problem. The purpose of making sense of Big Data is succeeding to extract valuable information to stand as decision support. In order to achieve that purpose and obtain valuable information from Big Data all components are used to process data and analyze the result to offer support for decision making.

As it may involve a significant decrease in the quality of life, health status and independence of the elderly, the early diagnosis and a personalized assistance become crucial in this ageing worldwide context. Current and emerging technologies provide the needed support for implementing appropriate new models of healthcare delivery. This paper highlights how RO-SmartAgeing system, which aims to provide customized monitoring and assistance for an elderly in his home, is designed for addressing a particular health condition as MIC. The associated smart environment is presented, together with the data flow chart and architecture, with an emphasis on MIC approach.

The disruptive potential of this paradigm is based on the inherent complementarity of Cloud computing and Internet of Things technologies. This particularity generates mutual benefits for both technological domains and provides a significant potential for developing complex, value added services. Considering the multi-source specificity of these services, their integration in a coherent offer with the "single point of contact" principle in mind is expected to facilitate the market penetration of these services. The paper proposes the Cloud-IoT service offer integrator role implementing this principle. Its business profile is outlined and its interactions along the supply chain are identified. Based on this information the business model specifications are presented in terms of customer segments, value propositions, channels, customer relationship, revenue streams, key resources, key activities, key partnerships, and cost structure.

Five papers provided by authors of Universities and R&D Institutes from different countries bring their contributions to this theme. In particular, the need of supply chain management models and tools is the main focus addressed by these authors. Almost all of them consider the current Production Planning and Control (PPC) systems quite inflexible to directly support the complexity of managing a cooperative enterprise network. In addition, they propose alternatives to overcome the difficulties involving planning aspects of a supply chain, and discuss possible directions to improve the supply chain management as a whole.

The global ageing population puts a burden on healthcare systems not only from the point of view ... more The global ageing population puts a burden on healthcare systems not only from the point of view of cost-related aspects, but also from the senior patients' point of view who tend to be predominately empowered regarding their own health management, digitally-skilled and demanding for personalized health protocols and solutions. Silver Digital Patients can be defined as seniors that master improved abilities of using digital technology in their daily activities, including in monitoring their health, who prove increased interest in having access to the best healthcare to preserve as much as possible their independence and health. An active, decent and safe life for seniors is at its best in their own homes; therefore, a remote health monitoring represents the most appropriate way to smooth the disruptive degenerative age-related factors, together with the important benefit of relieving the expenditures for senior institutionalizations. In this respect, emerging senior-centered technologies have the potential to provide a reliable support for building the most appropriate healthcare provision and environment. Internet of Health Things (IoHT) is a concept for a great variety of devices connected to the Internet that are able to gather a huge amount of diverse data - like health or environmental parameters - in order to keep a close remote watch on the patient, to improve the diagnose of his/her health status and to establish a better preventative healthcare. Edge computing brings the potential of improving the performance and responsiveness of IoHT by allowing the real-time collected data to be pre-processed closer to the source, which can be extremely important for time-sensitive health data in order to identify and trigger anticipatory or reactive health actions. This paper presents a case study -" Non-invasive monitoring and health assessment of the elderly in a smart environment (RO-SmartAgeing)" project - that evaluates the opportunities brought by IoHT and edge computing for a monitoring application. The general objective of this project is to demonstrate the potential of some emerging technology for the positive transformation of how healthcare services are provided to the seniors and to healthcare provider. According to its current development state, a proposed IoHT-based architecture of the monitoring application and a data analytics demo for a health parameter is presented.

The Cloud-IoT architecture integrates cloud computing and Internet of Things technologies to highlight the advantages derived from their complementarities. The sensing service is aimed at improving the sensor data accessibility and usage. Starting from the overall scenario of this service, the paper proposes an HM oriented Sensing Service scenario (HM-SS) with the aim to improve the service quality and accessibility, considering the increasing interest for this service which comes not only from large medical facilities but also from small ones (clinics, general practitioners) where the outpatient setting is specific. The interaction of the medical staff with the sensing service provider for the service setting up and its operation is detailed and main implementation rules are formulated.
