The IFIP AICT series publishes state-of-the-art results in the sciences and technologies of information and communication. The scope of the series includes: foundations of computer science; software theory and practice; education; computer applications in technology; communication systems; systems modeling and optimization; information systems; ICT and society; computer systems technology; security and protection in information processing systems; artificial intelligence; and human-computer interaction.Edited volumes and proceedings of refereed international conferences in computer science and interdisciplinary fields are featured. These results often precede journal publication and represent the most current research.The principal aim of the IFIP AICT series is to encourage education and the dissemination and exchange of information about all aspects of computing.

Massive hemoptysis and/or recurrent expectoration of measurable amounts of blood are common complications of chronic bronchopulmonary infections in cystic fibrosis (CF). When conservative treatment fails to control bleeding, surgery or bronchial artery embolization (BAE) is frequently considered. We present our experience and long-term follow up of BAE in 14 CF patients (age range 15-39 years) with massive (6 subjects) and/or recurrent (8 subjects) hemoptysis not responsive to medical treatment. Seven had chronic hypercapnic respiratory failure. After angiographic evaluation, polyvinyl alcohol particles (Ivalon) were injected to embolize obviously enlarged bronchial arteries. Seventeen procedures were performed in 14 patients and 36 bronchial arteries were embolized. All the patients stopped bleeding immediately upon BAE. Most of the patients had postembolization fever, dysphagia, and transient chest pain which were managed symptomatically. After a median follow-up period of 10.5 months (range 0.5-38 months), no recurrence of hemoptysis was observed in 8 patients who are still alive. In 3 patients hemoptysis recurred and they underwent reembolization after 3, 22, and 25 months, respectively. Three subjects died of respiratory failure within 5 months from BAE. Presently, 50% of patients studied had a > or = 1 year interval free of major hemoptysis after the first BAE. Our experience indicates that massive and/or recurrent hemoptysis in CF patients can be safety and effectively managed by BAE if the procedure is performed by a skilled practitioner. The procedure was well tolerated and resulted in prolonged and satisfactory bleeding control in most patients.

With the rapid development of manufacturing towards the vision of Industry 4.0, considerable efforts should be done in order to improve the manufacturing skills of young generations and to prepare them to the challenges of the new industrial world. For this reason, the paper first analyzes the learning requirements for the education and training about advanced manufacturing topics and the most suitable educational approaches to satisfy them, identifying digital game-based learning (DGBL) as one of the most promising. On this basis, the Life Cycle Assessment (LCA) Game, a digital game (DG) aiming at supporting the comprehension of LCA for sustainable manufacturing, is presented. Thanks to its high scalability and focus on the practical implications of the use of LCA in an industrial context, the suitability of LCA Game for both universities and companies is shown. Finally, the potentialities of digital game-based learning applications for manufacturing are discussed

A case of a 17-year-old boy presenting with a traumatic carotid-cavernous sinus fistula (CCSF), associated with an intracavernous pseudo-aneurysm, is reported. On angiography, the CCSF proved to be a direct and low-flow shunt. Conservative management was chosen and definitive closure of the fistula was obtained in two months by daily self-compression of the common carotid artery.
