The article considers the effect of cross-linked copolymer of potassium and ammonium salts of acrylic acid "Aquasin" on grapevine plants that were freed from contamination through the cul-ture in vitro. The study was held on the basis of Ya.I. Potapenko All-Russian Research Institute for Viticulture and Winemaking on the native Don variety Krasnostop zolotovsky. The aim of the work was to study the effectiveness of the use of hydrogel for the post vitro stage. The ways of its application were investigated. Hy-drogel was added to the soil substrate in a dry form and in a gel-like form saturated with nu-trients. As a result, it was noted that the hydro-gel does not affect survival. For all variants of the experiment, it was 98‒100 %. There was a positive effect of adding the water-retaining drug Aquasin to the substrate on the growth and development of plants. This was especially reflected in such indicators as leaf surface area, maturation and diameter of shoots. The positive effect was achieved on the 80‒90 day of adap-tation. In addition, the possibility of pre-saturation of the superabsorbent with im-munostimulants or fertilizers is of interest. Plant height and leaf area were maximal in the vari-ant with the addition of hydrogel saturated with an aqueous solution of minerals

Published: September 2022

In Chungcheong-do, a warehouse was operated to store Gunhyanggok. A total of five grain warehouses were operated. Each was founded at a different time, but its roles were similar. It was operated to prepare for unexpected expenditures or to stockpile in capacity during the war. However, Gunhyanggok could not be stocked for a long time. Since it is grain, it was difficult to store for a long time because it could easily rot. The positions of the government and local governments were different in Gunhyanggok, which was provided to the people for relief. The government wanted to operate it as a stockpile, and the provinces wanted to use it as a grain of relief. The Chungcheong provincial governor faithfully played a role in coordinating conflicts between the government and local governments.
The Process of Internationalisation of Polish Higher Education in Transition
Authors:   Korea Association of World History and Culture, Lee Ok-Jin
Published: September 2022

Jagiellonian University, the oldest university in Poland, was established in 1364, there were only seven universities until the 19th century. Even 21 universities were founded in the interwar years. Ups and downs of educational functions in Polish universities were due to Partitions of Poland, twice of World Wars and the socialist government.
Since the transition in 1989, Poland has experienced political and economic transformation. These transformations also took place in higher education and allowed Polish universities to ensure autonomy from political control. The internationalisation of higher education is one of the pivots of the changes that Polish universities had undergone over the past 30 years. As a result, many changes have occurred in the educational environment, research, and university administration. During the transition period of the 1990s, the internationalisation process was insignificant. Since the 20th century, Polish universities and academics have been gradually opened to the Western world. Also, Poland has experienced the process of internationalisation through the ERASMUS/SOCRATES Programme. On the other hand, Polish universities have to actively attract international students due to the decline of domestic students. The Polish government and universities continued their efforts to reform the system. In addition, the emergence of the World Academic Ranking of Universities (ARWU) and the influence and support from the European Commission, the OECD, and the World Bank have impacted on internationalisation of higher education and education reform in Poland. Through this process, higher education in Poland was able to enter the transnational education and research system, the European order.

Theoretical and methodological basis of financial risk management of a strategic enterprise
Authors:   Taras Shevchenko National University of Kyiv, MOTASHKO Tatiana , MARTYNIUK Viktoriia ,   Taras Shevchenko National University of Kyiv
Published: September 2022

Abstract. The approaches given in national and foreign scientific literature to the definition of the essence of financial risk management of strategic enterprises through the concepts of "financial risk" and "risk management" have been summarized. It has been identified that the category "financial risk" was considered by the authors from different angles and using different approaches. At the same time, in the economic literature, risks were mostly considered as the probability of financial losses. Accordingly, the main goal of risk management was aimed at managing the potential financial result, that is, at minimizing, limiting or neutralizing risks. It has been determined that financial risk management is a system of organizational and financial measures aimed to preventing, eliminating and limiting financial risks, as well as minimizing the cost of their financing. After all, the consequences of the existence of financial risks might be negative for any activity. It has been found that the financial risks of strategic enterprises do not differ from the risks of ordinary commercial enterprises. However, they are more potentially dangerous and require attention primarily from the state regulator. The drivers of the emergence of financial riskhave been identified, among which are: the dynamism of the country's economic sector; inflation; changes in market conditions; consumer demand; the emergence of new monetary instruments; market development; expansion of sales markets. The necessity of managing the financial risks of strategic enterprises has been substantiated. Also, the stages of financial risk management of a strategic enterprise have been considered, namely, risk analysis, control and financing. It has been established that a feature of modern financial risk management is a combination of qualitative and quantitative analyses. Approaches to the quantitative assessment of the strategic enterprises’ financial risks have been considered and the advantages of each of them have been indicated. Directions for improving the financial risk management of strategic enterprises in Ukraine have been proposed, namely: setting clear goals and forming a list of desired results of financial risk management; reforming the risk management strategy, the main goal of which should be risk prevention; investigation of all possible factors affecting the financial condition of the enterprise; introduction of a diversified assessment for each type of risk; improvement of the assessment stage through the formation of expert groups; development of an action program to reduce the degree and magnitude of risk; development of financial risk insurance, which in turn will reduce the burden on the state. Key words: financial risk; risk management; strategic enterprise; financial risk management; stages of risk management; qualitative risk analysis; quantitative risk analysis; drivers.

The ordering of relative clauses and determiner phrases in Chinese interlanguage: a multifactorial study
Authors: Xu Jiajin , Liu Zhaoxia
Published: September 2022

In English, a relative clause (rc) follows the head noun phrase (np). Conversely, the rc in Chinese precedes the head np directly before it or is separated by a determiner phrase (dp). This is uncommon in the subject-verb-object order language and results in two types of constructions. For Chinese as foreign language (cfl) learners, this construction alternation is complex to acquire and is dependent on many factors. This study aims to explore the underlying factors influencing cfl learners’ outer modifier nominal (omn)/inner modifier nominal (imn) alternation and whether they have multiple interactions. A multifactorial exploration of the significant predictors of the omn/imn alternation in Chinese interlanguage data, taken from the International Chinese Interlanguage Corpus, was conducted. Conditional inference trees and random forests were used to analyse the data. The predictors studied consist of head np animacy (HeadNPAnimacy), head np length (HeadNPLength), grammatical roles of head nps in matrix clauses (HeadNPMatRole), grammatical roles of head nps in rcs (HeadNPRelRole), length of rcs (RCLength), types of native languages (NLType), and learners’ Chinese proficiency (CHProficiency). Examinations of omn/imn alternation show predictors’ significant effects in descending order of their effect size: HeadNPRelRole, HeadNPMatRole, RCLength, NLType, and HeadNPAnimacy.
Material Green Entanglements: Research on Student Teachers’ Aesthetic and Ecocritical Engagement with Picturebooks of Their Own Choice
Authors: Campagnaro Marnie , Goga Nina
Published: September 2022

This article reports on a course module designed to promote an ecocritical and new materialist approach to children’s literature and to support student teachers’ skills regarding sustainability. The course module was offered in autumn 2020 and was completed by 260 students of children’s literature with no previous scholarly knowledge about ecocriticism prior to the course. Building on basic ecocritical theory, posthuman perspectives on humans’ intra-actions with material entities, and the students’ previous experiences with didactic tools for developing sustainability competencies through literature, the course module aimed to critically contribute to the implementation of the UN’s Sustainable Development Goals in teacher education. The research material consists of fifty-three video assignments by groups consisting of three to four students. The material has been analysed in line with the methodological implications of video content analysis, focusing on three aesthetic and material entanglements – that is, entanglements with picturebooks, with peers, and with the environment.

Cell-based tissue engineering approaches have emerged as a realistic alternative for regenerative disc tissue repair. The multidirectional differentiation potential of bone marrow mesenchymal stem cells (BMSCs) to treat disc degeneration intervertebral disc degeneration has also become a viable option. We used 1% HAMA hydrogel as a carrier and co-encapsulated BMSCs and Salvianolic acid B (SalB) into the hydrogel to reduce the apoptosis of the transplanted cells. The protective effect of SalB on BMSCs was first verified in vitro using the CCK8 method, flow cytometry, and Western-Blotting, and the physical properties and biocompatibility of HAMA hydrogels were verified in vitro. The rat model was then established using the pinprick method and taken at 4 and 8 W, to examine the extent of disc degeneration by histology and immunohistochemistry, respectively. It was found that SalB could effectively reduce the apoptosis of BMSCs in vitro by activating the JAK2-STAT3 pathway. 1% HAMA hydrogels had larger pore size and better water retention, and the percentage of cell survival within the hydrogels was significantly higher after the addition of SalB to the HAMA hydrogels. In the in vivo setting, the HAMA + SalB + BMSCs group had a more pronounced delaying effect on the progression of disc degeneration compared to the other treatment groups. The method used in this study to encapsulate protective drugs with stem cells in a hydrogel for injection into the lesion has potential research value in the field of regenerative medicine.
Inferring causal gene regulatory network via GreyNet: From dynamic grey association to causation
Authors: Chen Guangyi , Liu Zhi-Ping
Published: September 2022

Gene regulatory network (GRN) provides abundant information on gene interactions, which contributes to demonstrating pathology, predicting clinical outcomes, and identifying drug targets. Existing high-throughput experiments provide rich time-series gene expression data to reconstruct the GRN to further gain insights into the mechanism of organisms responding to external stimuli. Numerous machine-learning methods have been proposed to infer gene regulatory networks. Nevertheless, machine learning, especially deep learning, is generally a “black box,” which lacks interpretability. The causality has not been well recognized in GRN inference procedures. In this article, we introduce grey theory integrated with the adaptive sliding window technique to flexibly capture instant gene–gene interactions in the uncertain regulatory system. Then, we incorporate generalized multivariate Granger causality regression methods to transform the dynamic grey association into causation to generate directional regulatory links. We evaluate our model on the DREAM4 in silico benchmark dataset and real-world hepatocellular carcinoma (HCC) time-series data. We achieved competitive results on the DREAM4 compared with other state-of-the-art algorithms and gained meaningful GRN structure on HCC data respectively.
The deer play in Wuqinxi and four-point hand−knee kneeling positions for training core muscle function and spinal mobility

The four-point kneeling exercise is a core stabilization exercise that provides the spine with dynamic stability and neuromuscular control. In the traditional Chinese exercise Wuqinxi, deer play is performed in a hand−foot kneeling (HFK) position, which is remarkably similar to the four-point hand−knee kneeling (HKK) position. However, the differences in spinal function promotion between these two positions are poorly understood. The aim of this study was to investigate muscle activation patterns and spinal kinematics during specific core stabilization training to provide evidence for selecting specific exercises. A total of 19 healthy adults were recruited to perform HFK and HKK. The rotation angle of the C7–T4 vertebra and the surface EMG signals of abdominal and lumbar muscles on both sides were collected. The paired t-test showed that the vertebral rotation angles were significantly higher during HKK than HFK, and the intra-group differences mainly occurred at the level of the thoracic vertebra. The muscle activation of both sides of the rectus abdominis and external oblique in HFK was significantly higher than in HKK when the upper limb was lifted (p < 0.05). The activation of the ipsilateral lumbar multifidus and erector spinae muscles was significantly higher during the HKK position than during HFK when the lower limb was lifted (p < 0.05). HFK provided more training for strengthening abdominal muscles, while HKK could be recommended for strengthening lumbar muscles and increasing spine mobility. These findings can be used to help physiotherapists, fitness coaches, and others to select specific core exercises and develop individualized training programs.

Tunneling nanotubes (TNTs) are thin membrane tubular structures that interconnect physically separated cells. Growing evidence indicates that TNTs play unique roles in various diseases by facilitating intercellular transfer of signaling and organelles, suggesting TNTs as a potential target for disease treatment. The efficiency of TNT-dependent communication is largely determined by the number of TNTs between cells. Though TNTs are physically fragile structures, the mechanical properties of TNTs and the determinants of their mechanical stability are still unclear. Here, using atomic force microscope (AFM) and microfluidic techniques, we investigated the mechanical behavior and abundance of TNTs in human embryonic kidney (HEK293) cells upon the application of forces. AFM measurements demonstrate that TNTs are elastic structures with an apparent spring constant of 79.1 ± 16.2 pN/μm. The stiffness and membrane tension of TNTs increase by length. TNTs that elongate slower than 0.5 μm/min display higher mechanical stability, due to the growth rate of F-actin inside TNTs being limited at 0.26 μm/min. Importantly, by disturbing the cytoskeleton, membrane, or adhesion proteins of TNTs, we found that F-actin and cadherin connection dominantly determines the tensile strength and flexural strength of TNTs respectively. It may provide new clues for screening TNT-interfering drugs that alter the stability of TNTs.

Published: September 2022

Layered transition metal dichalcogenides (TMDs), such as molybdenum ditelluride (MoTe2), have attracted much attention because of their novel structure-related physicochemical properties. In particular, semi-metallic-phase MoTe2 (1T′) is considered as a competitive candidate for low-cost electrocatalysts for water splitting. However, there are few reports on the simple hydrothermal synthesis of MoTe2 nanostructures compared with other layered TMDs. In this study, a facile one-step hydrothermal process was developed for the fabrication of layered MoTe2, in which uniform nanotubes with a few layers of 1T′ MoTe2 were fabricated at a lower temperature for the first time. The as-obtained MoTe2 nanotubes were fully characterized using different techniques, which revealed their structure and indicated the presence of layered 1T′ nanocrystals. The efficient activity of MoTe2 nanotubes for the electrocatalytic hydrogen evolution reaction (HER) in 0.5 M H2SO4 was demonstrated by the small Tafel slope of 54 mV/dec−1 and endurable ability, which is attributed to the abundant active sites and remarkable conductivity of 1T′ MoTe2 with a few-layer feature. This provides a facile method for the design and construction of efficient layered MoTe2 based electrocatalysts.
