In the globalization era, in the 20th century, the development of Information and Communication Technology is very rapid. Even in the educational process, the teacher must be intelligent and able to choose the type of educational material he uses in the teaching and learning process. Educational materials play an essential role in the educational process and have an individual contribution to education, which impacts students. The problem in Wahid Hashim Balung Jember Islamic high school was the lack of unique education materials for reading skills. This study aims: 1) to determine the steps of developing reading materials for teaching Arabic through Android and 2) to determine the effectiveness of teaching reading materials for teaching Arabic through Android. This study uses the model approach proposed by Borg and Gall, and researchers use pre-test and post-test to develop reading materials. The results of this study showed that reading materials using Android developed by researchers effectively improve students ' reading skills.

Introduction. Packed red blood cells (pRBCs) are the most required component of blood used for transfusion. Storage of erythrocytes in blood bank conditions causes a disruption of the molecular structure of long-stored pRBC membranes. This “disruption” can affect the quality and safety of transfused red blood cells.Aim — to analyze the dynamics of pathological changes in the morphology, nanostructure, cytoskeleton network, and mechanical properties of RBC membranes during long-term storage of pRBCs, and the relationship of these changes with storage time.Materials and methods. Hermetic bags of pRBCs with anticoagulant CPD in resuspending solution SAGM were stored for 42 days at +4 °С. Samples were taken on days 3, 12, 19, 21, 24, 28, 35, and 42 of storage and images of morphology, nanostructure, and cytoskeleton were obtained by atomic force microscopy. Young’s modulus was used to assess the stiffness of native cell membranes using atomic force spectroscopy.Results. During storage of pRBCs, their cell morphology changed. After 20–24 days of storage an irreversible transformation of discocytes into echinocytes, spheroequinocytes and other cell forms occurred. It was found that during storage of pRBCs, topological defects in the form of domains with grains appeared on the surface of RBC membranes, the configuration of the cytoskeleton network transformed structurally, and the Young’s modulus increased.Conclusions. During long-term storage of pRBCs (up to 42 days, 4 °С, CPD/SAGM) the molecular structure of RBCs undergoes irreversible disorders. These changes occur, as a rule, after 20–24 days of storage.

Introduction. Acquired hemophilia is a rare autoimmune disease caused by an inhibitor to clotting factor VIII (FVIII). It complicates the course of many diseases, in particular autoimmune diseases, and in women is often associated with pregnancy.Aim — to present a case of successful treatment of a patient with acquired hemophilia using long-term continuous infusion of rFVIIa and inhibitor eradication as a result of immunosuppressive therapy.Main findings. A clinical observation of severe hemorrhagic syndrome in a patient with acquired hemophilia associated with pregnancy is presented. Uterine bleeding in the patient after spontaneous delivery, refractory to standard hemorrhagic syndrome treatment, required multiple surgical interventions. Laboratory tests showed prolongation of APTT, CT in the INTEM rotational thromboelastometry test, a decrease in plasma FVIII activity and presence of inhibitor to FVIII. Vacuum-assisted closure was applied to treat infected laparotomy wound. Therapy for acquired hemophilia consisted of hemostatic therapy and the inhibitor eradication. Hemostatic therapy included a continuous infusion of rFVIIa at a rate of 30 μg/kg/h with a gradual decrease up to 9.6 μg/kg/h, as well as its fractional administration before every surgery at a dosage of 80 μg/kg. The effectiveness of the therapy was assessed by the dynamics of CT in the INTEM test and the shortening of the APTT. The inhibitor eradication was achieved by prednisolone therapy, combined immunosuppression with rituximab and azathioprine, followed by its replacement with cyclophosphamide. As a result, the hemorrhage was stopped, reference plasma activity of FVIII and eradication of the inhibitor were reached.
Electrical properties of ferroelectric Y-doped Hf–Zr–O thin films prepared by chemical solution deposition
Authors: Sasaki Keisuke , Mohit  , Hashiguchi Sho , Tokumitsu Eisuke 
Published: July 2022

Abstract
Y-doped Hf–Zr–O (Y-HZO) films have been prepared by chemical solution deposition. It is shown that good ferroelectric property can be obtained for the Y-HZO film with a Y concentration of 3.2% after 800 °C crystallization annealing at a reduced pressure of 50 Pa. It is also demonstrated that the reduced pressure pre-annealing at temperatures as low as 400 °C is effective to obtain good ferroelectric properties, regardless of the crystallization annealing ambient. This is presumably because the pre-annealing under reduced pressure promotes the formation of nuclei in the orthorhombic phase.
Building a model of image formation of a higher education institution in Ukraine
Authors: Vasylenko Valeriia 
Published: July 2022

The article determines that to create a positive image, higher education institutions need to have a clear idea of what image they need, in this regard, the model of image formation is determined. The concept of the model of image formation of a higher education institution, which is a system of interconnected components of internal and external images of higher education, as well as the means of their formation and implementation to match the image markers of the audience that has a direct (static) impact on performance HEI for a long time. To create a model of image formation of the Ukrainian institution of higher education, three models were presented and characterized: model of the process of image formation of A. Rotovsky; model of corporate image formation B. Ji; model of image formation of I. Vikentyev. As a result of the analysis of the specified models the general recommendations on their improvement are presented.
The expectations of first-year higher education students of Ukrainian higher education institutions from the provided educational services in the 2017—2018 and 2018—2019 academic years were monitored. It was found that the main features that applicants paid attention to when choosing a higher education institution are: the quality of educational services with the necessary specialties, the possibility of internships abroad, employment with high wages, as well as the presence of well-known graduates and teachers. The most popular sources of information about the activities of higher education institutions for higher education seekers (acquaintances (relatives) studying at universities and official representations of the institution on the Internet (official website, social networks) are identified. A six-component model of image formation of a Ukrainian higher education institution is schematically presented; possible options for determining the expected effect (calculation of efficiency) of the implementation of image strategies in the activities of higher education institutions are considered.

Published: July 2022

The article considers the preconditions and possibilities of creating the Digital Platform of the Book Industry (DPBI) on the basis of the databases of the Book Chamber of Ukraine, formed during the years of independence, given the ecosystem of information interaction in the publishing industry.
It is emphasized that the digitalization of many processes in the publishing business, the COVID-19 pandemic and related quarantine restrictions have made significant adjustments to the technological structure of the industry, accelerating the process of book internetization. These factors are the main prerequisites for building a single information platform that unites publishers, libraries and users, providing them with quality information content and modern analytical services.
The branch tools which will form a basis of DPBI are considered. These are numerous resources of the Book Chamber of Ukraine, covering electronic catalogs: books, music, art, cartographic and electronic publications; UDC information arrays and UDC and BBK comparison tables; databases: retrospective bibliography, publishers, ISBN and ISMN agencies, print statistics and others.
The urgent problems that hinder the creation of the DPBI, in particular the modernization of the local computer network of the Book Chamber of Ukraine, the purchase of modern software, as well as a number of organizational issues.
