Zwycięstwo dotkliwsze od klęski. Udział wiedeńskiej 13. Dywizji Piechoty Landwehry w bitwie pod Limanową i Łapanowem
Authors: Woźny Tomasz
Published: February 2023

Viennese 13th Landwehr Infantry Division was one of the Austro-Hungarian divisions involved in the battle of Limanowa and Łapanów (December 1914). It consisted mostly of Austrian Germans and soldiers from Moravia. The division operated on the sector of the front, where toughest battles were fought. It attacked on Góra Świętego Jana and took part in the battle on the massif of Kobyła, and one of its regiments was also involved in the unsuccessful attack on Czyżyczka hill. The division was incomplete, with about 25% of its full strength, when it started to participate in the combat. It had not been able to top up the losses suffered in the previous battles.Participation in the victorious 10-day battle, resulted in a loss of 77% of the divisional infantry strenght. It was the highest percentage of losses among the Central Powers’ units in the battle of Limanowa and Łapanów. Despite that, the division retained its structures, technical units, rear and artillery which allowed to rebuild its combat potential in a short time.

Wyprawy Mścisława Mścisławowicza przeciw Węgrom i Polakom – wykorzystanie wsparcia oddziałów połowieckich w konfliktach zbrojnych
Authors: Michalski Michał
Published: February 2023

We know that Mstislav was married with the daughter of Polovtsian Khan Kotyan. His alliance with this Khan was one of the most important. Close contacts with Kotyan’s family had great influence on the opportunity to use the nomads in military expeditions. Polovtsian troops were used for the first time when the Alexander Prince of Belz moved to the enemy side (Leszek the White). Mstislav arrived in the company of the Polovtsian troops and supported Daniil and Vasilko. However, at this time he did not capture the Galich. Two years later Mstislav once again reached to the Polovtsian troops for help. In this case, nomads were used as reconnaissance troops (advance scouts) with the purpose to protect the main force and to recognize the situation at the place of the battle. The nomads arrived a day before the troops of Mstislav, their target was to “look” at the enemy troops. As we read in the Galician–Volynian Chronicle, Polovtsy completed their task superbly. Their help in the expedition contributed to the victory and enabled Mstislav to take control over the Galich.

Parents’ attitudes towards distance learning during the COVID-19 pandemic
Authors: Kolak Ante , Markić Ivan , Horvat Zoran
Published: February 2023

In this article we consider the applicability of distance education on the elementary level from parents’ perspectives and present the limitations stemming from the degree of support that students in elementary education need from their parents. The dilemmas regarding the possible levels of students’ development of independence and self-orientation, and the parents’ roles are highlighted. We believe that due to these limitations, distance learning has some of the characteristics of home-schooling. The subject of the research in the empirical part of this study focused on parents’ attitudes. Parental attitudes, based on a previously established multi-factor model, become clear from the parents’ experiences (Kolak, Markić & Horvat, 2020) where factors regarding the demands of teaching and the competence of parents as substitute teachers, were separated. Parents’ characteristics (e.g., gender, age, educational status and involvement) were found to influence their attitudes. The results of the research indicate the importance of parents in distance learning during the pandemic which adds a new and more significant role in the educational process of their children.
Approaches to early diagnosis and prevention of cardiovascular toxicity induced by targeted drugs and immune checkpoint inhibitors in oncohematology: a literature review

Published: February 2023

The development of targeted drugs and immune checkpoint inhibitors (ICIs), as well as their implementation into clinical practice has allowed increasing the overall and event-free survival of oncohematological patients. Currently, assessment of the efficacy of a therapeutic strategy in each specific case includes the evaluation of an acceptable tolerability profile. The subject of discussion includes cardiovascular complications induced by target drugs and ICIs. The review mainly presents the issues of cardiovascular toxicity (CVT) in certain groups of oncohematological patients (with chronic lymphocytic leukemia, chronic myeloid leukemia, multiple myeloma). The spectrum of cardiovascular adverse effects associated with targeted and ICI therapy in oncohematological practice is quite wide — coronary artery disease, peripheral arterial disease, myocarditis, heart failure, arrhythmias, hypertension. The high importance of the problem of using targeted and immunosuppressive therapy dictates the need to predict adverse effects. The diagnosis of heart failure (one of CVT manifestations) is based on determining the decreased left ventricular ejection fraction during echocardiography, less often — during cardiac magnetic resonance imaging; global longitudinal myocardial strain is a significant parameter of preclinical heart failure, which is determined using the speckle tracking technique. To determine vascular toxicity, a special attention is paid to the vascular wall structure and microcirculation parameters — capillary density at rest, percentage of capillary recovery and perfused capillaries, stiffness index for large blood vessels, reflection index for small arteries, laboratory markers of inflammation and endothelial dysfunction (C-reactive protein, fibrinogen, homocysteine, endothelin 1, vascular endothelial growth factor). CVT prevention presumes the determination of the risk group, correction of risk factors, and administration of protective therapy to very high and high-risk patients. One of the promising directions for preventing vascular toxicity is the use of sodium-glucose linked transporter-2 inhibitors.

A patent foramen ovale (PFO) is a fairly common mild cardiac defect that causes a shunting across the atrial septum. PFO is also a known risk factor for cryptogenic stroke. Much less frequently, PFO is associated with non-cerebral systemic embolic events. The article describes a case series of paradoxical embolism of the coronary arteries (CA), which caused myocardial infarction (MI). The presence of PFO was confirmed by imaging techniques. Subsequently, the patients underwent successful endovascular closure of the PFO. Thus, paradoxical CA embolism is a rare and underdiagnosed cause of acute MI. It should be considered in patients with MI and a low risk of atherosclerotic coronary artery disease. However, in most cases, it is not possible to verify the source of the embolism. The significance of occluder implantation as one of the treatment tactics requires further clarification.

Published: February 2023

Aim. To analyze the differences in detection rate of prefrailty and frailty syndrome (FS) in male and female patients with multivessel coronary artery disease (CAD) undergoing elective coronary artery bypass grafting (CABG).

Material and methods. The study included 387 patients admitted for elective primary CABG. Screening for prefrailty and FS in patients before surgery was performed using the questionnaire "Age is not a drawback".

Results. In the age group of 45 to 59 years, 25% of females and only 6% of males had signs of FS, while 25% of women and 34% of men did not present with signs of frailty and prefrailty. Half of middle-aged women and 60% of middle-aged men had prefrailty. Between the ages of 60 and 74, only 14% of women and 24% of men were not frail. Elderly women are more likely than elderly men to present with signs of FS (p=0,040). The symptoms of prefrailty in elderly patients were detected at equal rate in men and women (59% and 60%, respectively). All senile-aged patients presented with the signs of prefrailty or FS.

Conclusion. Patients with multivessel CAD present with manifestation of frailty in senile, elderly, and middle age. At the same time, middle-aged and elderly women with the higher rates of comorbid disorders require special attention.

Authors: Lukina Yu. V. , Kutishenko N. P. , Martsevich S. Yu. , Drapkina O. M.
Published: February 2023

Aim. To assess quality and adherence to pharmacotherapy (PT) based on the developed integrated indicators in a cohort of outpatients with stable exertional angina.

Material and methods. Using the expert evaluation method for main parameters of quality and compliance to PT, formulas were developed for calculating integrated indicators — the quality factor of PT (QFPT) and the rational PT index (RPTI). QFPT and RPTI are measured as a percentage; if the value is less than 50%, the parameters determined by them are considered unsatisfactory. In a cohort of 590 patients with stable exertional angina (men, 55,8%; mean age, 65,1±9,6 years), QFPT and RPTI were calculated. To assess the quality parameters of PT, data from patient registration forms were used, while adherence was determined using a 4-question validated score. After 21-month follow-up, primary composite endpoint was assessed: all-cause death, cardiovascular evens; an analysis of adverse outcomes was performed depending on QFPT and RPTI values.

Results. In patients with exertional angina, QFPT of 0% was determined in 8 (1,4%) people, while every sixth patient (16,4%) received unsatisfactory PT (QFPT <50%). In the majority of patients (419 (82,4%) people), RPTI was less than 50%. In subgroups of patients with RPTI <50% and >50%, there was a significant difference in the Kaplan-Meier survival curves, according to the log-rank test (p=0,006). The hazard ratio (RR) in the Cox regression model showed a threefold significant increase in the risk of adverse outcomes with RPTI <50%: HR=3,0, 95% confidence interval (1,14; 7,92), p=0,026.

Conclusion. The developed QFPT and RPTI make it possible to assess the quality of PT and performing a comprehensive assessment of the quality and adherence to PT, respectively. A relationship between low RPTI and a threefold increase in the risk of adverse outcomes in patients with stable exertional angina was revealed.
PARTNERING THROUGH IT: CONFRONTING THE INSTITUTIONAL CHALLENGES FACING DUAL-CAREER ACADEMIC COUPLES
Authors: Monahan Torin , Fisher Jill A.
Published: February 2023

Purpose: Meeting the needs of dual-career academic couples can be an important step in recruiting and retaining university faculty and researchers. The goal of this essay is to review the existing scholarship on dual-career hires and offer concrete recommendations for university administrators.

Background/Motivation: Attending to dual-career needs is especially relevant to efforts at diversifying the academic workforce, as multiple studies have indicated that faculty appointments are a major contributor to the so-called leaky pipeline causing attrition of women and scholars of color, particularly in biomedical and STEM fields. We take it as a feminist imperative to confront institutional discrimination against dual-career scholars and to intervene in the service of collective praxis.

Intended Audience: Scholars and administrators interested in understanding and overcoming institutional barriers to achieving diverse, inclusive, and family-friendly academic workplaces.

Contribution: This essay synthesizes the recent literature on dual-career hires and offers recommendations for university administrators.

Positionality: We approach this issue as a senior academic couple that has navigated dual-career job searches for close to twenty years and has held faculty positions together at three different academic institutions. We are a white, hetero dual-career academic couple interested in developing resources for individuals striving to activate change at their universities.

Gelation at a temperature below the freezing point of a solvent is known as cryogelation, which has attracted attention in regenerative medicine due to its improved mechanical and structural properties. This study focuses on using cryogelation as a versatile method for fabricating biomimetic scaffolds with improved mechanical strength and larger pore sizes with potential for bone tissue engineering applications. Scaffolds comprising carboxymethyl chitosan/gelatin/nano-hydroxyapatite were formed through cryogelation. The effects of three parameters – namely, cross-linker concentration, mineral content and gelatin-to-polymer ratio – on physical, chemical and mechanical properties were investigated. In this work, MG63 cells were used for an in vitro assay. In addition, an in vivo assay was conducted to investigate the biocompatibility of the nanocomposite scaffolds. The results showed that all scaffolds have a porous structure with interconnected pores with a morphology similar to bone structure. Their pore size, porosity and swelling ratio decreased with an increased cross-linker concentration, while nano-hydroxyapatite had the opposite effect. X-ray diffraction results also showed that the inorganic phase retained its crystallinity in the substrate with a slight decrease in crystal size. In addition, the scaffolds showed no toxicity in either in vitro or in vivo studies. The obtained results showed that biomimetic cryogels based on carboxymethyl chitosan/gelatin/hydroxyapatite have potential for bone tissue engineering.

Published: February 2023

Machine vision plays an increasingly important role in industrial product quality detection. During processing, scratches, dents and other defects are inevitable on the surface of a smooth part. Although surface defects do not affect the overall performance of the product, their existence
is unacceptable when a perfect product is required. The surface defect detection method based on machine vision and deep convolutional neural networks overcomes, to a certain extent, the problem of low detection efficiency, high false detection and missing detection rates in the traditional
detection method. In this paper, a multistream semantic segmentation neural network is proposed to identify defects on smooth parts. Taking a seatbelt buckle as an example, the scratch and crush defects on the surface are classified. The network takes DeepLabV3+ as the framework and three
types of image stream as the input of the network. In the backbone feature extraction network, the Xception structure is improved to MobilenetV2 and the convolutional block attention module (CBAM) is introduced into the decoding network, which improves the operational efficiency and accuracy.
Compared with other classical networks, this network demonstrates good performance in the image dataset of the seatbelt buckle and realises fast and accurate semantic segmentation and classification of surface defects. The evaluation results of the network model have been significantly improved.
Study on the steering capability of a meander-line coil EMAT
Authors: Hurrell S , Charlton P , Mosey S , Rees-Lloyd O , Lewis R
Published: February 2023

Electromagnetic acoustic transducers (EMATs) are well-established as a means of ultrasonic wave generation and reception without the use of a mechanical coupling. When comprising a bias magnetic field and a meander-line coil (MLC), these waves propagate at an angle normal to the emission
surface. With the appropriate frequency, the propagation pathway of these ultrasonic waves can be steered to a particular angle. This paper presents the methodology used to find the steering limit of an MLC EMAT and the results from simulations and experimental validations on aluminium. The
results show that the maximum shear wave amplitude occurred at around 30°, the steering limit was approximately 50° and the simulations were validated by the experimental set-up to a satisfactory degree.

Authors: Chandra Shekhar Majumder  , M. Shafiqul Alam  , Hosne Ara  , Robiul Islam  , Sheikh Mohammad Rashedul Haque
Published: February 2023

Background: A pterygium, known as surfer's eye, is a raised, wedge-shaped growth of the conjunctiva that extends onto the cornea, the outer layer of the eye. Aim was to compare the safety, efficacy and outcome of suture less technique with suture of conjunctival autograft in the management of pterygium.
Methods: This study was carried out in the department of ophthalmology, Sir Salimullah medical college and Mitford hospital, Dhaka. Study period was July 2019 to June 2020. Subjects for this study were divided into two groups, forty patients were enrolled in each group of the study population. Group I (control) comprised the subjects in whom suture was used following pterygium excision and conjunctival autograft and group II (experimental) comprised the subjects in whom no suture was used following pterygium excision and conjunctival autograft.
Results: In group I, 20% were 20-29 years old, 30% were 30-39, 27.5% were 40-49, and 22.5% were over 50, with 77.5% being male and 22.5% female. In group II, 22.5% were 20-29 years old, 27.5% were 30-39, 30% were 40-49, and 20% were over 50, with 72.5% being male and 27.5% female. The most common symptom was "foreign body sensation" in both groups. In group I, 5% experienced partial graft dehiscence, 2.5% a conjunctival cyst, 10% hyperemia, and 17.5% visual improvement. In group II, 2.5% had partial graft dehiscence, 2.5% hyperemia, and 22.5% visual improvement. Neither group had graft retraction or recurrence.
Conclusions: Postoperative presentation like hyperemia was significantly less in experimental group. Incidence of post-operative complications like graft dehiscence and conjunctival cyst were comparatively less frequent in suture less technique. Thus, suture less technique following pterygium excision and conjunctival autograft is a safer and less complicated than sutured technique.

Published: February 2023

The worldwide economy has been greatly impacted by COVID-19 pandemic, and it has had a huge impact on the capital markets. This paper aims to investigate the impact of COVID-19 on the performance of companies listed on the Stock Exchange of Thailand (SET) using quarterly financial data of listed companies from 2016 to 2021 to predict corporate performance. The results show that the COVID-19 outbreak negatively impacted Thai firm performance, especially in the service, resource, real estate, and manufacturing industries, due to the implementation of a wide range of policies to control the spread of the virus. The findings support earlier research that the pandemic has had a serious negative impact on firm performance. However, uncertainty will remain until COVID-19 ends; policy implementations should facilitate these suffering industries in the short and long runs. This study addresses the research gap regarding the impact of COVID-19 on emerging economic activity from a firm-level perspective.

Published: February 2023

Background: Genetic factors are significantly have important role in the etiology of the polycystic ovary syndrome (PCOS). This study examined the possible relation of rs1484215 and rs6495096 polymorphisms of CYP11A1 gene in Iranian women with PCOS.
Methods: The population of the case-control research included 100 women presenting with PCOS and 100 women as a control group who were referred to Infertility Center in Qom, Iran. The genotypes of rs1484215 and rs6495096 polymorphisms in CYP11A1 gene were detected with the tetra-ARMS PCR method. The independent segregation of alleles was tested for the Hardy–Weinberg equilibrium (HWE). Differences in quantitative traits were assessed between each group with a single PCOS feature and control group using Mann–Whitney U test for categorical variables and student’s t-test for continuous variables. Statistical analysis of allele and genotype frequencies between women with PCOS and control was performed using the chi-square test. Significance level was defined as p<0.05.
Results: There was a significant association of C with G alleles in rs6495096 polymorphism and susceptibility to PCOS (p=0.001), but no significant relation was found between C and T alleles in rs1484215 polymorphism and susceptibility to PCOS. Also, GG genotype of rs6495096 was significantly associated with the waist-to-hip ratio (WHR) and infertility duration compared to CG and CC (p<0.01). However, rs1484215 showed no association with these variables.
Conclusion: The results from the research indicated that rs6495096 polymorphism of CYP11A1 gene is related to the PCOS risk in Iranians women.

Published: February 2023

Background: Gestational trophoblastic neoplasia (GTN) is a group of tumors highly responsive to chemotherapy. It has been suggested that cancer therapies have detrimental effects on female fertility. Anti-Müllerian hormone (AMH) is considered fertility potential and ovarian reserves in women. The aim of this study was to compare serum AMH levels between the patients with GTN treated with chemotherapy and the patients with hydatidiform mole who underwent suction curettage without receiving any chemotherapy.
Methods: In 35 patients with GTN, serum AMH levels were measured before suction curettage and after the administration of chemotherapy and compared with serum AMH levels measured in 35 patients with hydatidiform mole, who did not receive any chemotherapy as a control. In controls, serum levels of AMH were measured before suction curettage and at the time when beta human chorionic gonadotrophin (ß-hCG) levels approached zero concentration.
Results: The mean serum AMH levels in the GTN group were significantly lower than those measured in the control group after chemotherapy. In addition, serum AMH levels measured after intervention in each group significantly decreased compared to the basal levels (p=0.034). Serum AMH levels showed significant differences between the patients who received chemotherapy regimens with methotrexate (MTX) alone, actinomycin-D (Act-D) alone, or the combination of MTX and Act-D (p=0.001).
Conclusion: Our study showed that fertility preservation is of great importance in patients with GTN treated with chemotherapy. Furthermore, both MTX and Act-D could have potential adverse effects on ovarian reserve.

Forage sorghum (Sorghum bicolor L.) has been grown in diverse climate variations, in warm and dry regions, or in regions with short drought periods. Thus, there is a need to select sorghum genotypes adapted to production systems under drought or rainy irregularities. This study evaluated the direct and indirect correlations among morphophysiological and productive characters of forage sorghum genotypes with Pearson’s correlation and path analysis. The experiment was designed under complete randomized blocks, with 25 treatments (genotypes) and three replicates. Analyzes of phenotypic correlation and the path analysis were done for plant height, panicle length, stem diameter, plant stand, green matter and dry matter yields, stem weight, plant weight, panicle weight, dry matter content, and forage mass. Plant weight presented the most significant direct effect on the forage mass (target variable), contributing to the increase in forage sorghum production. Therefore, heavier plants are more suitable to select forage sorghum genotypes indirectly, aiming to increase forage mass.

The appropriate arrangement of sorghum plants combined with the supply of nutrients increases grain yield. In this context, the objective was to evaluate the agronomic performance of grain sorghum grown under different plant arrangements and nitrogen fertilization levels. Experiments were carried out in Rio Verde and Montividiu in a 3 x 2 factorial randomized completely block design with six replications, with three spacing between rows (reduced, traditional and double row) and the use or not of 90 kg ha-1 topdressing nitrogen. There was a beneficial effect of topdressing nitrogen fertilization on grain yield when sorghum was grown in double rows in both locations, and for the reduced arrangement in Montividiu. However, the effect of topdressing nitrogen fertilization on grain yield in the traditional arrangement was not found. The dry shoot biomass of sorghum plants increased with nitrogen fertilization in Montividiu. The arrangement or topdressing nitrogen fertilization did not influence the thousand-grain weight of Sorghum.

Bei der Verifizierung der These vom grundsätzlich auf Kaszubsko-Krajeńskie Seenplatte beschränkten Auftreten der Kreise, wurden 8, in bisherigen Zusammenstellungen nicht notierten Fundstellen ausser diesem Gebiet festgelegt (Abb. 1). Auf Grund der Handschrift vom Jahre 1789 wurde ihre Anwesenheit in Biała, Kłoda und in der Gegend von Łomnica festgestellt. Der Kreis aus Grodno wurde auf Grund des beschreibenden Teils einer Sage von verzauberten Musikern und Tänzern, die gegen das Jahr 1837 (Abb. 3) abgefasst worden war, rekonstruiert. Der Bericht von Brummer aus Broczyn erlaubte, den Kreis und das Hügelgrab mit Steinkranz aus Swierczyna graphisch wiederherzustellen (Abb. 4). Informationen über solche Bauten wurden auch in den Berichten von Forschungen in Dorotowo (Abb. 2), Pawłówek und Krępsk notiert. Während der z eitgenössischen Terrainuntersuchungen wurden 2 Kreise im Zelgniewo lokalisiert (Abb. 5). Die Ergebnisse der durchgeführten Untersuchungen vergrösserten die Zahl der Fundstellen mit Kreisen bis 26 und die Zahl der Kreise selbst bis 45. (Tab. 1). Das Objekt aus Grodno ist zur Zeit der grösste Kreis von solchem Typ und hat etwa 38 m. Darchmesser. Die Kreise aus Zelgniew gehören zu den kleinstem und jeder hat etwa 12 m. Durchmesser. Mit den dargestellten Objekten aus Swierczyna und Biała können wahrscheinlich die aus Literatur bekannten Gräberfeldfunde verbunden werden.
Die dargestellten Objekte ändern die These vom Auftreten der ähnlichen hauptsächlich in der Zone der Kaszubsko-Krajeńskie Seenplatte. Neue Kreise werden weit südwestlich von dieser Anhäufung lokalisiert was sich deutlich mit maximalen Bereich der Вesiedlung der Wielbark-Kultur in der Unterstufe B2 und B2/C1 deckt. Man soll noch einmal auf grosse Möglichkeiten der Wiederherstellung vom Netz der Objekte mit Steinkreisen aufmerksam machen. Solche Möglichkeiten stecken in der Rundfrage des alten archäologischen Schifttums- darin der Sagen.

This research aims to comprehend the interconnecting threats and vulnerabilities facing underprivileged women from marginalised religious groups in Nigeria from the angle of gender discrimination from their neighbouring communities as well as their host societies. It also extends to discrimination shown to people on the basis of their religious background as well as socioeconomic biases endured by poor women from marginalised religious groups. The research also aims to exhume and illuminate the societal experiences of women as an undermined group compared to men of the same faith, including how discrimination from the wider society affects both groups. It looks at cultural and socioeconomic vulnerability of these women and aims to learn from their experiential knowledge by listening to their stories first hand.

Most of the research on school dropout has analytically privileged the subjects who drop out of school, thus relegating the subjects who remain. This has resulted in an empirical and conceptual vacuum in studies on school dropout and, finally, a biased view of the phenomenon. For this reason, the purpose of this article is to analyze the intra-family relationships that allow generating the conditions that make it possible for the student to stay in the schools of the telesecundaria subsystem. Qualitative research was carried out under a case study. The subjects of analysis were families whose children are in third grade in the telesecundaria subsystem. After analyzing the empirical evidence with a qualitative data analysis program, it was concluded that staying in school is associated with a nuclear family model. Likewise, it is shown that there is a causal relationship between the socioeconomic level of these families and the extracurricular investment in their children.

In this work new methods to obtain complexes from β-cyclodextrin and dehydroabietic acid with chromenol-triazol hybrid with the sizes limits of approximately 0.1-250 μm are reported. Kneading, co-evaporation and co-precipitation for the resolution of racemic 2-tert-butyl-3-(1H-1,2,4-triazol-1-yl)-2H-chromen-2-ol for obtaining micro- and nanoparticles have been optimized. In vitro dissolution studies of the synthesized compounds in phosphate buffer (pH 6.8) showed an improved dissolution rate of chromenol-triazol hybrid in the inclusion complexes compared to the free form. The obtained β-complexes of β-cyclodextrin loaded with dehydroabietitoic acid and chromenol hybrid showed good antibacterial activity with MIC and MBC values ranging from 0.72 to 44.45 μM.

Relevance. Computer simulation is a mathematical modeling process performed on a computer that is designed to predict the behavior or results of a real or physical system. Computer simulation has a number of advantages over classical models of animal experiments: the cheapness of the method (the need to acquire and maintain animals disappears by itself), the speed of obtaining results, the absence of bioethical problems, the ability to change the conditions of the experiment, etc.

he purpose of this study is to review the methods of computer simulation of the wound process, to identify the shortcomings of the models and propose ways to solve them, as well as to select the best existing model for describing wound regeneration.

Material and methods. In the course of this work, an analysis was made of foreign and domestic literature on the problem of computer modeling of the wound process.

Results. After analyzing the relevant literature on this topic, the problem is seen precisely in the insufficiently studied process of wound regeneration, since many different cells, cytokines, growth factors, enzymes, fibrillar proteins, etc. take part in it. The models that currently exist describe wound regeneration only in an extremely generalized way, which does not allow us to apply them in clinical situations. Analyzing literature sources, we came to the conclusion that both numerical approaches, both cellular-biochemical (the first type of models) and phenomenological (the second type) are applicable in the case of wound modeling and can be used very successfully. The problem is that on the basis of one approach it is impossible to display a complete picture of wound healing, in this way it is possible to predict only individual regeneration parameters necessary for certain purposes due to the complexity and versatility of this typical pathophysiological process.

Conclusion. Computer modeling of wounds is still a controversial and complex topic. Existing models are not intended to describe all the processes occurring in a healing wound. It is much more productive to describe the various phenomena during healing separately. This is due to the fact that many elements are involved in the regeneration of the skin, which are almost impossible to take into account in full. The available models are of exclusively scientific value, consisting in attempts to understand all complex processes and interactions. Practical application is difficult, since existing models require specific input data that require highly specialized equipment. If we abstract from all this, then the best existing model of the first type is the model of the authors Yangyang Wang, Christian F. Guerrero-Juarez, Yuchi Qiu and co-authors, in addition to it, any of the described phenomenological models will do.
Financial Crises and Financial Contagion in Latin America
Authors: Ovcharov A.
Published: February 2023

The article deals with modern financial crises and features of their spread in Latin America. The classification of crises and ways of their identification are presented. The interconnectedness of modern financial crises is emphasized, which leads to the emergence of double and triple crises. Such crises have been repeatedly recorded in Argentina, Mexico, Uruguay and other countries. Over a period of more than fifty years, Latin America experienced 165 financial crises, with the largest share of them occurring in currency crises. The article proposes the indicator “crisis burden on the countries of Latin America” – its calculation for the period 1970–2019 showed that the region is characterized by alternating growth and decrease in the burden from banking and currency crises with a relatively stable load from debt crises. The maximum intensity of financial crises was observed in the 1970–1980, and then it decreased, although there were isolated spikes. The interconnectedness of crises is analyzed in the context of the effects of financial contagion – the transmission of shocks through different channels from one country or region to another country or region. Two main approaches explaining the mechanisms of transmission of crises between countries have been allocated. The results of studies indicating the direction and extent of financial contagion in Latin America were discussed. In particular, it is shown that contagion in the crisis periods of 1990–2000 spread both within the region and from the United States through trade and financial channels. The article presents the results of its own empirical study, which also confirmed the existence of contagion in this region. For the calculations, daily data on the stock indices of 8 Latin American countries over a long period of time were used. With the help of econometric tests for shifts in correlations (Forbes-Rigobon test and coskewness test), it was found that the recipients of contagion that spread through the stock market channels from the United States during the global financial crisis of 2007–2009 were countries such as Argentina, Brazil, Colombia and Mexico. During the crisis caused by the spread of COVID‑19, only Mexico was susceptible to contagion. This made it possible to draw a conclusion about the resilience of Latin American economies to the pandemic shock and the effectiveness of restrictive government measures.
On China’s Modern Foreign Policy Through the Prism of the Concepts of “Dao” and “Shi”
Authors: Song Zhihao
Published: February 2023

China’s diplomatic approach under Xi Jinping is notably distinct from previous eras. Instead of pursuing the road of peaceful development, China appears to have abandoned its self-positioning as a “ancient civilized country” and has grown increasingly aggressive in the international community. Western academics and journalists have even coined the term “war wolf diplomacy” to characterize this trend. However, the author contends that this transformation is unavoidable since China is in the process of discovering itself, which implies that it is modifying its foreign policy in response to the genuine demands of its own development, defining its diplomatic “dao”. One of the most significant aspects in this procedure is the “shi” and only by accurately assessing, following, and planning the “shi” can the aforementioned duties be completed more effectively and finally achieve the aim of successful rising. In this paper, the author not only discusses classical Chinese philosophical writings in order to select key points from the sages’ thought for analyzing and explaining modern Chinese foreign policy, but also demonstrates some of the more successful theoretical constructions of the Chinese school of international relations theory. The author begins the first part by debating the “Way of the King” and “hegemony strategy”, pointing out that currently China’s foreign policy applies both concepts, with the former principle assisting China in implementing the fundamental principal of “not solving international problems by force”. While the “hegemonic” strategy is largely utilized to give a powerful reaction to external challenges, as indicated by the rising number of (counter)sanctions imposed in recent years. The author wants to present a reasonable explanation for China’s change in foreign policy style in the second half of the paper. According to him, this change represents a sound strategic decision by the Chinese leadership to “act in line with the ‘shi’”. However, because the transformation is still in its early stages, it is not yet feasible to foresee the eventual conclusion, therefore the overall trend in China’s foreign policy today should be judged in a way that does not unnecessarily laud or discredit it.

Published: February 2023

This study, titled The Effect of Computer Simulation on Grade 11 Learners’ Conceptualisation of Stoichiometric Chemistry, was carried out at a school in the Frances Baard District of the Northern Cape province of South Africa. Poor conceptualisation of stoichiometric chemistry by learners in Grades 10-12 in South Africa and, hence, their failure to apply the concepts to problem-solving in the same and other topics in chemistry, is a cause for concern. The study was conducted with the theoretical framework of activity theory. A mixed method design that consisted of a pre-test post-test experimental design, a questionnaire and interviews were used for the study. Two Grade 11 physical sciences classes which consisted of a control and experimental group were taught stoichiometric chemistry after the SCAT pre-test. The experimental group obtained an intervention comprising computer simulations during teaching, while the control group was taught using the lecture method. The ANOVA results showed that learners of the control and experimental groups were comparable in terms of prior knowledge of the topic of stoichiometric chemistry. The paired t-test showed that both groups improved their performance in stoichiometric chemistry. However, the ANCOVA results showed that the experimental group had a greater improvement in performance than the control group. The results of the SCAT post-test, observation of lessons, questionnaire and interviews showed that the experimental group conceptualised stoichiometric chemistry better than the control group. The quantitative and qualitative data was triangulated, and it also indicated that the experimental group conceptualised stoichiometric chemistry better than the control group. It is therefore suggested that using computer simulations for the teaching and learning of stoichiometric chemistry is a better method to improve its conceptualisation in the FET phase of schools in South Africa.
