Human capital for digital economy modernization

The article outlines the scientific approaches to the formation of digital technologies of the ecosystem of professional education and management of the formation of human capital for the real sector of the Russian economy. It has been proposed to highlight specific competences as training units (quantums), digitize them, create a level classifier and build an ordering system, a system of choice used for order fulfillment, a continuous (from general education to professional education for a given position) professional education system based on individual educational trajectories with well-defined (digitized) parameters and focused investments in human capital. Using the formed systems, it has been proposed to provide digital modernization of the main didactic processes with guaranteed achievement of specific diagnosed learning outcomes in accordance with the order.For new competencies it is possible to develop ontological models of employee professional activities. Herewith it is planned to solve several important tasks, including the development and adoption of a general concept of continuous professional education, the selection and classification of didactic units for specific professions, the development and introduction of a classification system for educational organizations according to their levels of competence, the development and introduction of a system for qualifying teachers, formation of a system of educational trajectories (necessary competencies) for business, development of pedagogical technologies standards that guarantee the achievement of results (the right people - in the right place - at the right time). It has been offered to select several branches of the real sector of the economy for the implementation of pilot projects with the subsequent dissemination of experience throughout the Russian economy

It provides separation of mineral complexes according to magnetic properties, density and size. Magnetic-gravity separators (MGS) have been designed and their parameters are defined, It has been shown that MGS enables to obtain 1.5-3.0% improvement in Fe content in concentrates and to produce super concentrate (72% Fe, 0.2-0.3% SiO2). MGS also provides for intensification of thickening and desliming of ferromagnetic suspensions.</span

Supplementary Material for: Admission Hypocalcemia and the Need for Endoscopic and Clinical Interventions among Patients with Upper Gastrointestinal Bleeding

Introduction: Calcium is an essential co-factor in the coagulation cascade and hypocalcemia is associated with adverse outcomes in bleeding patients, including trauma patients, women with postpartum hemorrhage, and patients with intracranial hemorrhage. In this retrospective, single-center, cohort study, we aimed to determine whether admission ionized calcium (Ca++) is associated with higher rates of therapeutic interventions among patients presenting with acute non-variceal upper gastrointestinal bleeding (NV-UGIB). Methods: Adult patients admitted due to NV-UGIB between 1/2009-4/2020 were identified. The primary outcome was defined as a need for clinical intervention (two or more packed cell transfusions, need for endoscopic, surgical, or angiographic intervention). Univariate and multivariable logistic regression analyses were performed to determine whether Ca++ was an independent predictor of the need for therapeutic interventions. Propensity score matching was performed to adjust the imbalances of covariates between the groups. Results: A total of 434 patients were included, of whom 148 (34.1%) had hypocalcemia (Ca++<1.15mmol/L). Patients with hypocalcemia were more likely to require therapeutic interventions than those without hypocalcemia (48.0% vs. 18.5%, p<0.001). Specifically, patients with hypocalcemia were more likely to require endoscopic intervention for control of bleeding (25.0% vs. 15.7%, p=0.03) and require multiple packed cell transfusions (6.8% vs. 0.3%, p<0.001). Additionally, they had significantly longer hospital stay (5.0 days [IQR 3.0-8.0] vs. 4.0 days [IQR 3.0-6.0], p=0.01). After adjusting for multiple covariates, Ca++ was an independent predictor of the need for therapeutic intervention (aOR 1.62, 95% CI 1.22–2.14, p<0.001). The addition of Ca++ to Modified Glasgow Blatchford score improved its accuracy in the prediction of therapeutic intervention from AUC of 0.68 (95% CI 0.63-0.72) to 0.72 (95% CI 0.67-0.76), p=0.02. After incorporation of the propensity score, the results did not change significantly. Conclusion: These findings suggest that hypocalcemia is common and is associated with an adverse clinical course in patients with NV-UGIB. Measurement of Ca++ on admission may facilitate risk stratification in these patients. Trials are needed to assess whether correction of hypocalcemia will lead to improved outcomes
