Evaluation and utilisation of privacy enhancing technologies-A data spaces perspective.

Data sharing has facilitated the digitisation of society. We can access our bank accounts or make an appointment with our doctor anytime and anywhere. To achieve this, we have to share certain information, whether personal, professional, etc. This may seem like a minor cost for an individual user, but actually the data economy as the backbone of a digital transformation that is reshaping all aspects of human life. However, one of the major concerns arises regarding what happens to such individual data; once shared, control over it is often lost. For that reason, users and companies are reluctant to share their data. The European Union, through its European Strategy for Data, is establishing a policy and legal framework for establishing a single market for data in Europe by improving the trust and fairness of the data economy. Data spaces are a commitment to sharing data in a reliable and secure way, but this endeavour should, of course, not be at the expense of privacy rights. In recent years, Privacy-Enhancing Technologies (PETs) have emerged to achieve data sharing and privacy preservation that can address the requirements of data spaces around sensitive citizen and business data. In this work, we review existing PETs and assess their relevance, technological maturity, and applicability in the context of common European data spaces. Finally, we illustrate the benefits of secure data sharing via Federated Learning in a healthcare use case, where the preservation of privacy is a primer requirement and is therefore to be guaranteed.

[Bronchoscopic assessment algorithms for the practical evaluation of the rheological properties of the tracheobronchial secretion and the classification of the degree of the disordered drainage function of the tracheobronchial tree (TBT) in chest and combined trauma with chest trauma as the leading injury]. / Bronkhoskopski otsenuchni algoritmi za prakticheska otsenka na reologichnite svoistva na trakheobronkhialniia sekret i klassifikatsiia na stepenta na narushena drenazhna funktsiia na trakheobronkhialnoto durvo (TBD) pri grudni i suchetani travmi s vodeshta grudna travma.

Ventilation impairment, due to ineffective elimination of the mucous-hemorrhagic content from the tracheobronchial tree (TBT), obstructs the upper airways with the ensuing ventilation reduction giving rise to atelectases and progressive alveolar block. There is evidence of transudation and exudation into the pulmonary pathways and pleural cavity. A series of 276 patients presenting closed chest trauma are subjected to fibrobronchoscopy (FBS) and follow-up study. In 92 of them bronchoscopy is performed 2 to 15 times per patient, accordingly: in 75-twice, in 10-five times and in 15-twice. One-hundred twenty-nine of the total of 276 cases under study are on mechanical ventilation. In 56 instances FBS is carried out through a tracheostomy cannula, in 73-by intubation, in 18-through the mouth, and in two--through the nose. Based on the obtained results, algorithms for assessment of the rheological properties of tracheobronchial secretion and degree of impairment of TBT drainage function during emergency FBS in closed chest injuries are worked out, having an essential practical bearing on the diagnostic and therapeutic approach to closed thoracic trauma.
