The article is devoted to the definition of the essential characteristics of economic security of private enterprises and its main components; it is proposed to expand the main structural elements of the system of economic security of private enterprises. The main functional objectives of economic security are: ensuring the high financial efficiency of work, financial stability and independence of private enterprises on a industry scale; ensuring technological independence and achieving the high competitiveness of the technical potential of small business enterprises; achievement of high efficiency of management; achievement of a high level of personnel qualification and its intellectual potential; Minimizing the devastating impact of the results of industrial and economic activity on the state of the environment; qualitative legal protection of all aspects of the activity of private enterprises, etc. It is proposed to consider the system of economic security of private enterprises as an integral set of subjects and objects of security, an environment that ensures their interaction and purposeful activity in the internal and external environment in relation to countering threats, protection of economic interests and, in general, creation of safe conditions for functioning at the planned level indicators. Attention is drawn to European experience and standards in the field of business security, but to take into account the fact that private enterprises of Ukraine are forced to operate in more difficult and dangerous conditions than in developed countries, therefore, during the period of the current stage of reforms in the sphere of private entrepreneurship, it is recommended to introduce normative and legal base which would fine-tune the peculiarities of functioning of private enterprises and create favourable conditions for the emergence of the economic crisis in order to create a reserve of strength in the event of unforeseen circumstances, as private enterprises are a significant component of the economic security of the state.

This chapter assesses Europe’s efforts in developing a full-fledged strategy on the human and ethical implications of artificial intelligence (AI). The strong focus on ethics in the European Union’s AI strategy should be seen in the context of an overall strategy that aims at protecting citizens and civil society from abuses of digital technology but also as part of a competitiveness-oriented strategy aimed at raising the standards for access to Europe’s wealthy Single Market. In this context, one of the most peculiar steps in the European Union’s strategy was the creation of an independent High-Level Expert Group on AI (AI HLEG), accompanied by the launch of an AI Alliance, which quickly attracted several hundred participants. The AI HLEG, a multistakeholder group including fifty-two experts, was tasked with the definition of Ethics Guidelines as well as with the formulation of “Policy and Investment Recommendations.” With the advice of the AI HLEG, the European Commission put forward ethical guidelines for Trustworthy AI—which are now paving the way for a comprehensive, risk-based policy framework.

Element Method

The inverse Finite Element Method (iFEM) is receiving more attention for shape sensing due to its independence from the material properties and the external load. However, a proper definition of the model geometry with its boundary conditions is required, together with the acquisition of the structure’s strain field with optimized sensor networks. The iFEM model definition is not trivial in the case of complex structures, in particular, if sensors are not applied on the whole structure allowing just a partial definition of the input strain field. To overcome this issue, this research proposes a simplified iFEM model in which the geometrical complexity is reduced and boundary conditions are tuned with the superimposition of the effects to behave as the real structure. The procedure is assessed for a complex aeronautical structure, where the reference displacement field is first computed in a numerical framework with input strains coming from a direct finite element analysis, confirming the effectiveness of the iFEM based on a simplified geometry. Finally, the model is fed with experimentally acquired strain measurements and the performance of the method is assessed in presence of a high level of uncertainty.

Abstract Background Children affected by Coronavirus disease 2019 (COVID-19) showed various manifestations. Some of them were severe cases presenting with multi-system inflammatory syndrome (MIS-C) causing multiple organ dysfunction. Case presentation We report the case of a 12-year-old girl with recent COVID-19 infection who presented with persistent fever, abdominal pain and other symptoms that meet the definition of MIS-C. She had lymphopenia and a high level of inflammatory markers. She was admitted to pediatric intensive care unit since she rapidly developed refractory catecholamine-resistant shock with multiple organ failure. Echocardiography showed a small pericardial effusion with a normal ejection fraction (Ejection Fraction = 60%) and no valvular or coronary lesions. The child showed no signs of improvement even after receiving intravenous immunoglobulin, fresh frozen plasma, high doses of Vasopressors and corticosteroid. His outcome was fatal. Conclusion Pediatric patients affected by the new COVID-19 related syndrome may show severe life-threatening conditions similar to Kawasaki disease shock syndrome. Hypotension in these patients results from heart failure and the decreased cardiac output. We report a new severe clinical feature of SARS-CoV-2 infection in children in whom hypotension was the result of refractory vasoplegia.

ABSTRACT The YadA protein is a major adhesin of Yersinia pseudotuberculosis that promotes tight adhesion to mammalian cells by binding to extracellular matrix proteins. In this study, we first addressed the possibility of competitive interference of YadA and the major invasive factor invasin and found that expression of YadA in the presence of invasin affected neither the export nor the function of invasin in the outer membrane. Furthermore, expression of YadA promoted both bacterial adhesion and high-efficiency invasion entirely independently of invasin. Antibodies against fibronectin and β1 integrins blocked invasion, indicating that invasion occurs via extracellular-matrix-dependent bridging between YadA and the host cell β1 integrin receptors. Inhibitor studies also demonstrated that tyrosine and Ser/Thr kinases, as well as phosphatidylinositol 3-kinase, are involved in the uptake process. Further expression studies revealed that yadA is regulated in response to several environmental parameters, including temperature, ion and nutrient concentrations, and the bacterial growth phase. In complex medium, YadA production was generally repressed but could be induced by addition of Mg2+. Maximal expression of yadA was obtained in exponential-phase cells grown in minimal medium at 37°C, conditions under which the invasin gene is repressed. These results suggest that YadA of Y. pseudotuberculosis constitutes another independent high-level uptake pathway that might complement other cell entry mechanisms (e.g., invasin) at certain sites or stages during the infection process.

Submerged Combustion

It is well known that high-level radioactive wastes (HLRAW) are usually vitrified inside electric furnaces. Disadvantages of electric furnaces are their low melting capacity and restrictions on charge preparation. Therefore, a new concept for a high efficiency combined aggregate – submerged combustion melter (SCM)–electric furnace was developed for vitrification of HLRAW. The main idea of this concept is to use the SCM as the primary high-capacity melting unit with direct melt drainage into an electric furnace. The SCM employs a single-stage method for vitrification of HLRAW. The method includes concentration (evaporation), calcination, and vitrification of HLRAW in a single-stage process inside a melting chamber of the SCM. Specific to the melting process is the use of a gas-air or gas-oxygen-air mixture with direct combustion inside a melt. Located inside the melt are high-temperature zones with increased reactivity of the gas phase, the existence of a developed interface surface, and intensive mixing, leading to intensification of the charge melting and vitrification process. The electric furnace clarifies molten glass, thus preparing the high-quality melt for subsequent melt pouring into containers for final storage.

The Impact

Purpose The American Society of Clinical Oncology (ASCO) Cancer Research Committee designed a qualitative research project to assess the attitudes of cancer researchers and compliance officials regarding compliance with the US Privacy Rule and to identify potential strategies for eliminating perceived or real barriers to achieving compliance. Methods A team of three interviewers asked 27 individuals (13 investigators and 14 compliance officials) from 13 institutions to describe the anticipated approach of their institutions to Privacy Rule compliance in three hypothetical research studies. Results The interviews revealed that although researchers and compliance officials share the view that patients' cancer diagnoses should enjoy a high level of privacy protection, there are significant tensions between the two groups related to the proper standards for compliance necessary to protect patients. The disagreements are seen most clearly with regard to the appropriate definition of a “future research use” of protected health information in biospecimen and data repositories and the standards for a waiver of authorization for disclosure and use of such data. Conclusion ASCO believes that disagreements related to compliance and the resulting delays in certain projects and abandonment of others might be eased by additional institutional training programs and consultation on Privacy Rule issues during study design. ASCO also proposes the development of best practices documents to guide 1) creation of data repositories, 2) disclosure and use of data from such repositories, and 3) the design of survivorship and genetics studies.

Dwarf Rootstocks

Columnar apple cultivars are optimally suited to lay apple tree plantings using intensive technology, which provides for super-dense placement of trees. The article considers a variant of growing columnar apple cultivars on inserts of dwarf rootstocks 3-17-38 and 62-396. The use of dwarf rootstocks 3-17-38 and 62-396 as intercalar inserts in the cultivation of columnar apple cultivars, along with good anchoring of plants, provides high precocity, productivity and economic efficiency of planting. All the costs of laying the orchard and annual works on agrotechnical care of the trees were paid off in the fourth year after planting.The economic and biological features of the columnar cultivars provided not only a quick return of the investments, but also a high level of profitability. The profitability of the studied columnar planting for the 6th year after planting (2020) on average for all cultivars was 106.0 % on the insert of the dwarf rootstock 62-396 and 104.7 % on the insert 3-17-38. The profit received on average for the plantings amounted to 2 378 661 rubles per ha. In the group of the studied cultivars, there is a difference in economic efficiency. The lowest level of productivity and profitability was in the Vostorg cultivar: on average, on two inserts, the yield in 2020 was 27.3 t/ha and the profitability was 66.6%. The Girlyanda cultivar was characterized by the maximum yield and profitability: 88.0 t/ha and 115.8%, respectively.

The famous anthropologist Pierre Bourdieu argued that there is an “unnatural idea of inborn culture, of a gift of culture, bestowed on certain people by Nature.” [1] Bourdieu is arguing that people, who have not been born into a higher class, or who cannot receive a high level of education, are unable to appreciate and understand art. The study of art history is expensive, and often involves extremely high travel costs, thus making it inaccessible to anybody who does not enjoy the means to pursue it. How can we address this accessibility problem in the study of art history? Is there any way to bring art to the people who do not possess “inborn culture?” Bourdieu wrote his book on art and class in 1984, at a time when the computer, and its democratizing potential, was a new and little -understood invention. My research proposes that modern technology provides an answer to this problem, which has plagued the discipline of art history. This presentation will examine three research projects that I’ve been working on at Queen’s. Each project uses digital technologies to improve the general public’s knowledge and access to art. The projects are all different: the first focuses on creating a digital model of 18th - century Canterbury Cathedral based on a book from W.D. Jordan Rare Books and Special Collections, the second project works on understanding Herstmonceux Castle and medieval England through technology, and the third involves image processing for art historical investigations. Despite their differences, each project makes art accessible to people who do not possess Bourdieu’s definition of “inborn culture.”

Background The uptake and utilisation of allied health assistants as professional support staff has been variable across disciplines and jurisdictions. Although they are potentially very important in the current health workforce context, there is little agreement on their roles or the most suitable methods to define these roles. Method Based on a review of literature, existing role descriptions and focus groups, a Delphi survey process was undertaken. This process comprising three rounds of discussion and clarification via email, with between 107 and 188 participants, was undertaken to define and establish consensus on allied health assistant roles at three levels. Results Three cycles of editing, qualitative feedback and rating of agreement with statements resulted in substantial clarification of roles and a meaningful degree of consensus regarding the role and scope of such positions. High levels of agreement were not reached for more high-level or contested clinical tasks. Conclusions The Delphi process resulted in key tasks and roles being defined and contentious aspects clearly identified. The process facilitated engagement with workforce members most closely affected by these questions. It was a useful means of drawing together the opinions of the workforce and informing implementation trials to follow. What is known about the topic? Allied health assistants are important members of health teams. Current developments in health services necessitate considerable growth in these positions. The role and scope of practice of allied health assistants is poorly defined and varies between disciplines, settings and facilities, which threatens the establishment of these positions. What does this paper add? This study describes a methodology used to define the role and scope of practice of allied health support staff, which resulted in high levels of consensus and documentation of concerns regarding these positions. Tasks and roles have been defined at different allied health assistant position levels. What are the implications for practitioners? The definition of roles and establishment of scope of practice of emerging positions can be substantially advanced by well researched and widely consultative methods. For more advanced allied health assistant positions to be effectively implemented, tasks relating to treatment, leadership, documentation, assessment and team participation must be clearly elucidated and agreed.
