Introduction. In the context of the current postmodern upheaval, the need to define each trend and field in sciences dealing with the past gains special significance. The article attempts an analytical review of achievements in the study of the ‘women’s theme’ in contemporary historical sciences of Mainland China between 1949 and 1999. Goals. The work aims to examine the accumulation of knowledge concerning the ‘second sex’ (long considered non-principal); review the history of how previously unknown sources or overlooked aspects and plots relating to legal, family, social statuses of Chinese women have been introduced into scientific discourse; identify prerequisites and causes for the emergence of new fields in disciplines dealing with the past (women’s history of China and anthropology of gender); explore main stages in the development of the research trend to determine its significance for contemporary Chinese and world science. Results. The paper proves that the Fourth World Conference on Women (Beijing, 1995) served a dividing line in the shaping of the new history research agenda. It was after 1995 that corresponding academic endeavors were launched in various cities and universities, scientific schools formed, and their leaders came forth. Conclusions. The emergence of the new field in China’s science was inevitable since it had been predetermined by a change in cognitive orientations. Women’s history brought together those who were ready to combine Marxist methodology (with its deliberate attention to socioeconomic problems) with the concept of gender (which allowed an introduction of topics never studied by Chinese historians).

Published: June 2023

Abstract: This report shows the advancement of flight control systems, from the old human controlled mechanical systems to the modern fly by wire systems in use today. It also compares the two systems, and investigates the reasons behind the change. This change is a significant and an extraordinary representation of the advancements made in the avionic industry and of the development of aeronautical technologies. The fly-by wire system represents a large fast forwarding in the industry, from complex mechanically controlled systems, to large hydraulically controlled systems, to computer assisted fly by wire system. The use of fly-by wire systems has significantly reduce the weight of the flight control systems, while increasing the scope to add multiple redundancy flight control systems, which can increase the safety in case of failures in a particular system. Further development in fly-by wire systems comes in the form of advancing from analog to digital computing systems
A Study to Evaluate the Effectiveness of Planned Teaching Program Regarding Occupational Health and Hazard in Terms of Knowledge among Workers Working in Modi Continental at Modipuram Meerut, UP
Authors: Chaudhary Mrs. Monika
Published: June 2023

Abstract: Background of the study: Occupational health is a multidisciplinary activity aimed at the protection and promotion of the health of workers by preventing and controlling occupational diseases and accidents and by eliminating occupational factors and conditions hazardous to health and safety at work. Occupational risks and hazards are the health problems employees’ face in their work environment and how those health problems affect the health status of employee and their family. It can also be defined as diseases, accidents and other hazards arising from the work environment or situations that arise in the attempt to perform tasks in any occupation. It is a compensable disease that arises out of and in the course of employment. The process of rubber manufacturing is complex and continually changing, thus making the study of occupational exposures in the rubber industry difficult. Rubber workers’ route and compounds of chemical exposure depend largely on the specific employee work task and environment. In 1994, the Centers for Disease Control and the National Institute for Occupational Safety and Health summarized these various exposures. Thus this study was needed for the assessment of knowledge of factory workers so that they can be work in a safe and healthy working environmen

Anti-Soviet Speeches of the Khrushchev “Thaw” Period as One of The Results of Ill-conceived Managerial Decisions
Authors: Lushin A. I.
Published: June 2023

Goals. Based on the analysis of a Note to the Presidium of the Central Committee of the CPSU and a number of other sources, to show the causes and results of ill-conceived managerial decisions of the party and Soviet authorities that led to tragic consequences at the construction of the Karaganda Metallurgical Plant in Temir-Tau, Kazakh SSR in early August 1959.Materials and methods. As the basic materials of the work, the main provisions of the “Notes. The main method of working with sources and scientific literature is the retrospective method, which is traditional for this kind of research, which, in turn, allowed us to consider the causes and origins of a specific anti-Soviet speech, its development and historical finale. In addition, the study used a problem-chronological approach, which contributed to the study of specific aspects of the activities of party, Soviet, trade union, Komsomol organizations that somehow allowed the development of negative trends in the construction of the Karaganda Metallurgical Plant, to identify the causes of the origin and development of anti-government, and essentially anti-Soviet, speeches of workers who participated in the construction of the combine.results. One of the negative results of the policy of attracting significant masses of young people for the construction of “shock buildings of communism” was the unpreparedness of the party and Soviet local authorities to work in extreme conditions and constant overstrain of forces, their ability to create elementary conditions, not only for work, but also for catering, recreation, leisure of large masses of people focused on insignificant, in size, territories.Conclusions. The “shock construction of communist construction”, the construction of which attracted large masses, primarily young people, for almost all the years of Soviet power, allowed for almost three decades to erect a significant number of the largest industrial enterprises and facilities. The people who worked on their construction suffered a huge amount of inconvenience and deprivation, however, in the conditions of a rigid command and directive system and the absence of a developed civil society, it was extremely problematic to protect their civil rights. However, with the onset of the Khrushchev “thaw”, when terror and repression significantly decreased, there was some hope for solving many emerging issues, but the lack of a clearly working feedback between the government and society did not allow them to be solved by civilized means. The accumulated “combustible material”, one way or another, often resulted in mass open demonstrations against inept and ill-considered decisions of the authorities, which often ended in extremely tragic consequences, including the death of people.
On the Perceptions of Russia as an Educational Destination by the Students at German University
Authors: Savelchev L. А.
Published: June 2023

Purpose. The purpose of the article was to explore how Russia is perceived as an educational destination among undergraduate (B. A.) and postgraduate (M. A.) students at Rhine-Waal University of Applied Sciences (Kleve, Germany) during the summer semester 2022.Methods. The research was conceived as a reflective study based on the case-oriented research design and with a single case examined: the Rhine-Waal University of Applied Sciences (Kleve, Germany) and its undergraduate (B. A.) and postgraduate (M. A.) students. To address the research question: “How is Russia being perceived as an educational destination by undergraduate (B.A) and postgraduate (M.A) students at Rhine-Waal University of Applied Sciences in Germany?”, a mixed method was selected with archival and document-based research which was paired with a survey as a data collection technique; and a content analysis as a strategy for data analysis.results. Results of this survey have showed that 79% of respondents would like to visit Russia, but only 18% of respondents may consider Russia as a place to go studying (results are based on 33 replies out of 7390 students in total — the justification of small sampling is explained in the Methods part). Strikingly low interest to study in Russia was explained by 1) other educational destination preferences; 2) language barrier, and 3) lack of information on the Russian study programs and 4) insufficient financial support of studying in Russia. In addition, the survey results indicated that the negative perceptions of Russia as an educational destination could be related to the different values held by the students at the Rhine-Waal University of Applied Sciences, and those held by general population in Russia (as perceived by the students), but this would require further investigation.Conclusions. There are three major findings resulting from this study. Firstly, there is an inadequate attention in International Relations’ literature on the influence of international student mobility and change in students’ worldview and values. Secondly, higher education and international student mobility are considered as one of the instruments for value promotion and factors contributing to the soft power of the states. Thirdly, the results of Rhine-Waal University of Applied Sciences case seem to confirm Sylvie Lomer’s hypothesis that students are already positively predisposed to the country where they intend to go studying.
Development of the St. Petersburg Tourism Cluster in the Framework of Creating New Attractiveness Factors for the Hotel Chain Through Mid-Range Apartments
Authors: Podolskaya E. А. , Misko О. N.
Published: June 2023

The purpose of this study is to identify the characteristic features of the process in which the tourism industry of St. Petersburg is becoming more popular due to the spread of middle-class apartments. The article considers the problems of the tourism industry associated with the consequences of the pandemic, as well as with the political and economic pressure of other countries. Possible solutions are proposed due to concessional lending for the construction of hotels and apart-hotels. As a result, the reasons why apartments are in high demand in the Russian Federation were revealed. We believe that the analysis carried out indicates the expediency of investing in the construction of apartments and bringing the lease into an official type of activity. In the future, this will lead to an increase in the quality of service to tourists, an increase in the level of satisfaction and an increase in the income of the industry. It is also necessary to introduce concessional lending programs, which in the long term will lead to the stimulation of the tourism industry, as well as related industries, including construction. The latter, in turn, is a driver of economic processes taking place in the Russian Federation.
Employment Strategies for Refugees and Forced Migrants: A Regional Aspect
Authors: Kolesnik E. А.
Published: June 2023

The movement of people from one place to another can be caused by a variety of factors, including conflicts in the military, political or socio-economic sphere, natural disasters and other situations that force people to seek safety in other countries. As a result, there is a change not only of the country of residence, but also of lifestyle, social status, place and type of employment. The situation, which is quite difficult for migrants, forces them to change and build employment strategies in proportion to the possibilities of labor realization in the country (region) of residence — labor market conditions, established labor regimes, peculiarities of remuneration and labor incentives, etc. The purpose of the article is to conduct an empirical study of the employment strategy of refugees and forced migrants. The object is refugees and forced migrants from Ukraine who arrived on the territory of the Tyumen region. The relevance of the topic is due to the fact that forced migration is a global problem, and the possibility of “embedding” migrants, especially forced ones, has a decisive impact on the economic aspects of the country and the development of its regions. The significance of this study is particularly high and on the basis of the fact that there is a shortage of qualified specialists in various industries in the Tyumen region and the labor market is characterized as labor deficient.The consideration of the problem is based on the use of various methods of scientific analysis, the main of which are survey and statistical methods, methods of generalization, systematization and grouping; official data of international organizations dealing with the problem under consideration, official statistics of the Russian Federation and Tyumenstat, official data of the Federal Migration Service of Russia and the Migration Department of the Ministry of Internal Affairs of Russia are reflected in the work in the Tyumen region. The results consist, firstly, in the study of common problems faced by refugees and forced migrants in the labor market of the Tyumen region, secondly, in the study of the features of labor integration of migrants from Ukraine, thirdly, in the consideration of employment strategies for refugees and forced migrants for their successful integration into the regional labor society.

Introduction: In fatal accidents during scuba diving, it is necessary to differentiate a death from primary drowning from a secondary drowning death that is primarily due to other etiopathogenetic factors. The inhalation of water can only be the end point of a series of events capable of causing the diver’s exitus. This study aims to demonstrate that even low-risk heart disease in daily life become potentially fatal during scuba diving. Methods: In this case series, we describe all cases of deaths in the course of diving that came to the observation of the Forensic Institute of the University Bari over 20 years (2000-2020). A judicial autopsy was performed on all subjects, with ancillary execution of histological and toxicological investigations. Results: The results of the medicolegal investigations carried out in the complex identified heart failure with acute myocardial infarction as the cause of death in four cases characterized by severe myocardiocoronarosclerosis, a primary drowning in a subject without previous pathological substrate in one case, and a terminal atrial fibrillation induced by acute dynamic heart failure due to functional overload of the right ventricle in one case Conclusion: Our study demonstrates that lethal events during diving are often related to the presence of unrecognized or subclinical cardiovascular diseases. Such deaths could be prevented and avoided if a greater regulatory sensitivity to preventing and controlling diving was encouraged, considering both the inherent risks of this activity and the possible unrecognized or underestimated pathologies.

Background: This study sought to investigate therapeutic effects of hydrogen-rich saline (HRS) combined with hyperbaric oxygen (HBO2) in an experimental rat model of acute lung injury (ALI). Methods: Forty male Sprague-Dawley rats were randomly divided into sham, LPS, LPS + HBO2, LPS + HRS, and LPS + HBO2 + HRS groups. After an intratracheal injection of LPS-induced ALI, the rats were given a single-agent HBO2 or HRS or HBO2 + HRS treatment. The treatments were continued for three days in this experimental rat model of ALI. At the end of experiment, the lung pathological, inflammatory factors, and cell apoptosis in the pulmonary tissue were detected by Tunel method and cell apoptosis rate was calculated accordingly. Results: In the groups treated with HBO2 + HRS, pulmonary pathological data, wet-dry weight ratio, and inflammatory factors of pulmonary tissues and alveolar lavage fluid were significantly superior to those of the sham group (p<0.05). Cell apoptosis detection revealed that no single agent treatment of HRS or HBO2, or combination treatment , could alleviate all cell apoptosis. HRS combined with HBO2 treatment was superior to single treatment (p<0.05). Conclusion: HRS or HBO2 single treatment could decrease inflammatory cytokines release in lung tissue, reduce the accumulation of oxidative products and alleviate apoptosis of pulmonary cells, then lead to positive therapeutic effects on ALI induced by LPS. Furthermore, HBO2 combined with HRS treatment presented a synergy effect on cell apoptosis decrease and a decline in inflammatory cytokine release and related inflammatory product generation, compared with a single treatment.

Published: June 2023

Background: The pathophysiology of traumatic brain injury (TBI) is caused by the initial physical damage and by the subsequent biochemical damage (secondary brain injury). Oxidative stress is deeply involved in secondary brain injury, so molecular hydrogen therapy may be effective for TBI. Hydrogen gas shows the optimal effect at concentrations of 2% or higher, but can only be used up to 1.3% in the form of a gas cylinder mixed with oxygen gas, which may not be sufficiently effective. The partial pressure of hydrogen increases in proportion to the pressure, so hyperbaric hydrogen therapy (HBH2) is more effective than that at atmospheric pressure. Methods: A total of 120 mice were divided into three groups: TBI + non-treatment group (TBI group; n = 40), TBI + HBH2 group (n = 40), and non-TBI + non-treatment group (sham group; n = 40). The TBI and TBI + HBH2 groups were subjected to moderate cerebral contusion induced by controlled cortical impact. The TBI + HBH2 group received hyperbaric hydrogen therapy at 2 atmospheres for 90 minutes, at 30 minutes after TBI. Brain edema, neuronal cell loss in the injured hippocampus, neurological function, and cognitive function were evaluated. Results: The TBI + HBH2 group showed significantly less cerebral edema (p < 0.05). Residual hippocampal neurons were significantly more numerous in the TBI + HBH2 group on day 28 (p < 0.05). Neurological score and behavioral tests showed the TBI + HBH2 group had significantly reduced hyperactivity on day 14 (p < 0.01). Conclusion: Hyperbaric hydrogen therapy may be effective for posttraumatic secondary brain injury.

Published: June 2023

In immunocompetent patients with liver inflammation, the detection of
IgG and IgM antibodies against the hepatitis E virus (HEV) is important
for the diagnosis. Recently, fully automated chemiluminescence
immunoassays (CLIAs, LIAISON® Murex anti-HEV IgG/anti-HEV IgM test,
DiaSorin) have become available for this purpose. The diagnostic
suitability of these CLIAs was determined by comparison with a
combination of plate-based enzyme immunoassays ( recomWell HEV
IgG/IgM ELISA, Mikrogen) and immunoblots ( recomLine HEV IgG/IgM,
Mikrogen), which served as a reference for the characterization of sera.
Samples with a deviating result were retested with an alternative test
(WANTAI HEV IgG/IgM ELISAs). The anti-HEV IgG CLIA had a sensitivity and
specificity of 100% (100/100; 49/49) each when the recomWell HEV
IgG ELISA served as a reference. The anti-HEV IgM CLIA had a sensitivity
of 67.9% (36/53) and a specificity of 100% (49/49). When IgM
immunoblot results were considered, sensitivity and specificity were
88.9% (24/27) and 53.8% (14/26), respectively. The WANTAI test
confirmed 52.9% (9/17) of negative CLIA IgMs that differed from the
recomWell HEV IgM result. The CLIA revealed an isolated and thus
probably non-specific HEV IgM in one of 17 patients with acute
Epstein-Barr virus infection. The automated CLIAs are well suited for
HEV diagnostics.
Balancing between predation risk and food by boreal breeding ducks

Published: June 2023

1. Wetlands belong to the globally most threatened habitats, and
organisms depending on them are of conservation concern. Wetland
destruction and quality loss may affect negatively also boreal breeding
ducks in which habitat selection often needs balancing between important
determinants of habitat suitability. In Finland duck population
trajectories are habitat-specific, while the reasons behind are not
known. 2. In this research, the balance of nest predation risk and
invertebrate food abundance in boreal breeding ducks was studied in
Finland at 45 lakes and ponds in 2017 and 2018. Nest predation
experiments were conducted with artificial nests followed by wildlife
cameras during seven days. Invertebrates were sampled from the study
water bodies using emergence and activity traps. Duck pairs and broods
were also surveyed from these and 18 additional water bodies. 3. The
wildlife camera results indicate that predation risk was higher in the
water bodies surrounded by agricultural land than forestland. Ponds
(seasonal, beaver and man-made) had lower nest predation risk and they
were also more invertebrate-rich habitats than permanent lakes. In
addition, artificial nests further away from water bodies had higher
survival than shoreline nests. Habitat use of duck pairs (prior to
nesting) was not associated with invertebrate food, but duck broods
preferred habitats rich in food. 4. High nest predation pressure in
shorelines of especially agricultural landscapes may contribute the
declining population trends of ducks in Finland. Controlling predators
would be an important conservation action to improve duck breeding
success. This research underlines the benefits of the availability of
different water body types for the breeding ducks. There is an urgent
need to pay attention to protecting seasonal ponds, while the lack of
flooded waters may be mitigated by favouring beavers or man-made ponds.

MXenes are mentioned in many applications due to their unique
properties. However, the traditional etching method has a long synthesis
time, dangerous process and high cost. Molten salt etching is not only
short in time, but also safe and simple, laying a good foundation for
industrialization. Here, we compare the traditional F–containing
etching method with the molten salt etching method. TEM elemental
mapping images and XPS show that the Ti3C2Tx surface end of traditional
etching is terminated by –F, while the Ti3C2Tx surface end of molten
salt etching is terminated by –Cl. Finally, the sodium–ion batteries
is fabricated and the performance difference of the three etching
methods is compared, the results show that the capacity of 102.1 mAh
g–1 can still be reached when the molten salt etching MXene material
returns to 0.1 A g–1 after the current density of 5 A g–1. After 500
cycles at 1 A g–1, there is no significant loss of capacity and the
coulomb efficiency is close to 100%. This work describes that molten
salt etching MXene has comparable sodium storage capacity to
conventional F–containing etched MXene, making it a potential candidate
for large–scale sodium–ion batteries production.

Authors: Mahmood Munazza , Aziz Dr.Shamsa , Bibi Dr.Memoona
Published: June 2023

Teaching practice gives a chance to prospective teachers to acquire professional skills, teaching methods, and different techniques of teaching. The main objectives of this study were to find out the effect of teaching practice in shaping prospective teachers’ professional identities and to compare prospective teachers and cooperative teachers’ perceptions about effects of teaching practice on professional identities. Research questions and hypothesis were formulated to achieve the main objectives of the research.  Data were collected from 45 cooperative and 80 prospective teachers selected through the purposive random technique. Data were collected through a questionnaire based on six main components of teaching practice contributing to shaping professional identities. Mean score was calculated to answer the research questions and t-test was applied to compare prospective and cooperative teachers’ perceptions. It is inferred from the findings that teaching practice plays an important role to overcome future classroom challenges. t-test results show a significant difference between prospective and cooperative teachers’ perceptions about teaching practice components. It is recommended that proper evaluation of teaching practice must be done, and prospective teachers’ feedback must be considered essential to overcome challenges of the teaching and learning process for future practices.

Published: June 2023

The aim of this study was to compare the number of Professional Development (PD) activities the teachers attended, compare them by demographic variables, and investigate the relationship between these activities and teacher leadership and life satisfaction. The study sample was determined by the simple random sampling method and consisted of 821 teachers working in various provinces in Turkey. The results of the study are summarized as follows: A significant weak positive correlation was found between the teachers' beliefs regarding the function and importance of PD activities and the total number of PD activities they attended in 2020. It was found that the teachers' monthly income and the PD activities they attended per week and per year had a significant positive effect on their leadership behavior and that the leadership behaviors of teachers had a significant positive effect on their life satisfaction.
Comparison of Economic Geography Contents in Turkey and Turkmenistan Geography Curriculum: Grades 10th, 11th and 12th
Authors: Sahin Vedat
Published: June 2023

Education curricula are programs that include topics for students’ academic achievement and individual development. Geography curricula cover many subjects such as physical, human, economic and environmental issues. In this study, the economic geography contents of Turkey and Turkmenistan high school geography curricula were compared in the study. Firstly, the content of 10th, 11th and 12th grades in the geography programs of both countries was investigated and evaluated. The study is qualitative in nature as it is mainly based on document analysis. Economic geography topics in geography programs according to grade levels were examined and the similarities and differences between the economic geography subjects in the geography programs of both countries were determined. In both countries, economic geography subjects are included in the 12-year compulsory education, especially after the 10th grade. Moreover, both programsinclude economic geography topics from a local to global scale.
Changes in the Vegetable Oil Market, with Particular Emphasis on Market Instability in Relation to the War in Ukraine
Authors: Sobczak-Malitka Wioleta , Sobczak Emilia
Published: June 2023

In the 21st century, the global production and consumption of oilseeds and their processing products are growing dynamically as a result of the globally growing demand for food and renewable energy. Globally, supply and demand factors have changed the edible vegetable oils industry. The production of vegetable oils is characterized by one of the highest dynamics among all agricultural raw materials, which results from the growing demand for vegetable oils for food, industrial purposes and the growing demand for protein feed. The cultivation of oilseeds plays an important role in Polish agriculture. On an industrial scale, the production of rapeseed oil dominates in Poland, and is a strategic product of the Polish agri-food sector. Sunflower and soybean oils are also of market importance. The scale of crude rapeseed oil production ranks Poland third in the European Union (after Germany and France) and sixth in the world. The country's share in EU rapeseed oil production is about 13%. Poland, despite the dynamic development of rapeseed production and processing which took place after 2004, has low self-sufficiency in the field of oilseed products, especially low in the field of oilseed meals (self-sufficiency at the average level of approx. 43% in 2018-2020) and oils vegetable crops (self-sufficiency at the average level of approx. 63%); therefore, it remains a permanent, large net importer.
Simulations and bisimulations for fuzzy multimodal logics over Heyting algebras
Authors: Stankovic Marko , Ciric Miroslav , Ignjatovic Jelena
Published: June 2023

In the present paper, we study fuzzy multimodal logics over complete Heyting
algebras and Kripke models for these logics. We introduce two types of
simulations (forward and backward) and five types of bisimulations (forward,
backward, forward-backward, backward-forward and regular) between Kripke
models, as well as the corresponding presimulations and prebisimulations,
which are simulations and bisimulations with relaxed conditions. For each
type of simulations and bisimulations an efficient algorithm has been
provided that works as follows: it computes the greatest
presimulation/prebisimulation of that type, and then checks whether it meets
the additional condition: if it does, then it is also the greatest
simulation/ bisimulation of that type, otherwise, there is not any
simulation/bisimulation of that type. The algorithms are inspired by
algorithms for checking the existence and computing the greatest simulations
and bisimulations between fuzzy automata. We also demonstrate the application
of these algorithms in the state reduction of Kripke models. We show that
forward bisimulation fuzzy equivalences on the Kripke model provide reduced
models equivalent to the original model concerning plus-formulas, backward
bisimulation fuzzy equivalences provide reduced models equivalent concerning
minus-formulas, while regular bisimulation fuzzy equivalences provide
reduced models equivalent concerning all modal formulas.
Solid Cauchy transform on the weighted poly-Bergman spaces
Authors: El Harti , Elkachkouri A. , Ghanmi A.
Published: June 2023

In the present paper, we deal with the weighted solid Cauchy transform C?s
(from inside the unit disc into the complement of its closure) acting on the
weighted true poly-Bergman spaces in the unit disc introduced and studied by
Ramazanov and Vasilevski. Mainly, we are concerned with the concrete
description of its range and its null space. We also give the closed
expression of their reproducing kernels. To this end, we begin by studying
the basic properties of C?s such as boundedness for appropriate probability
measures. The main tool is an explicit expression of its action on the
so-called disc polynomials which form an orthogonal basis of the considered
weighted true poly-Bergman spaces.
Estimates on some functionals over non-linear resolvents

Published: June 2023

Estimation of linear and quadratic functionals over different classes of
univalent functions is one of the classical problems in geometric function
theory. In this paper we solve the problem over some classes of so-called
non-linear resolvents, which arise as a fruitful tool in dynamic systems.
Sharp estimates on early Taylor coefficients and the Fekete-Szeg?
functional are established.

Stability of relative essential spectra involving relative demicompactness concept in Banach subalgebra
Authors: Chelly Slim
Published: June 2023

This paper develops the notion of relative demicompact elements of an algebra
with respect to a Banach subalgebra as a generalization of relative
demicompact linear operators acting on Banach spaces. Drawing on this novel
notion, we build a new class of Fredholm perturbation regarding a given
Banach subalgebra B which contains its inessential ideal kB and the set of
left Fredholm perturbations suggested in [6]. The developed class of
Fredholm perturbation exhibits that is a two-sided closed ideal of B that is
key in the characterization of the weyl spectrum of elements affiliated with
B.
