Background Bacterial virulence is a key factor determining the outcome of each bacterial infection and virulent bacteria are often associated to high-risk infections. Extraintestinal pathogenic Escherichia coli (ExPEC) is the most implicated bacterium in human bacterial infections and its virulence factors are classified into five categories: adhesins, toxins, iron capture systems, protectins and invasins. Furthermore, bacterial biofilms are the main cause of hospital-acquired infections like urinary catheter-associated infections, valve endocarditis, Otitis and cystic fibrosis.Results For the sixteen virulence genes sought by standard polymerase chain reaction (PCR), all the 78 ExPECs isolates carried at least four virulence genes. Following prevalences of virulence genes were reported: adhesins genes fimH (98.7%), mrkD (98.7%), papC (46.2%), afaC (9%), sfa / focDE (1.3%); iron acquisition systems genes entB (98.7%), fepA (98.7%), ybtS (93.6%), fyuA (91%), iucA (91%), iucB (91%), iutA (34.6), iroB (6.4%), iroN (6.4%) and toxins genes hlyA (10.3%), cnf (1 & 2) (10.3%). Seventy-five out of 78 isolates (96.2%) carried at least the combination of two adhesins genes and two iron capture systems genes whereas 8 out of 78 (10.3%) harbored the combination of (adhesins genes + iron acquisition systems genes + toxins genes). Among the 78 strains studied, one hospital-acquired strain isolated from urine harbored 15 virulence genes out of 16 sought. The evaluation of biofilm-formation capacity revealed that all (29/29) hospital-acquired isolates were biofilm producers with (6/29; 20.7%) strong biofilm producers, (15/29; 51.7%) moderate biofilm producers and (8/29; 27.6%) weak biofilm producers. Isolates carrying papC had greater biofilm formation capacity than those not carrying papC (p < 0.001).Conclusions Most of our strains had moderate biofilm-formation capacity and carried an average of 9 virulence genes out of 16 sought. These eight strains carrying a combination of genes (adhesins + iron acquisition systems genes + toxins genes) may be hypervirulent isolates. Additional studies may confirm this. The deepening of this kind of study on bacterial virulence and hospital bacterial biofilms could lead to the improvement of infections investigation, prevention and therapeutic protocols.

Published: May 2023

Introduction
Excessive dietary sodium (Na) consumption is a major health care issue in the developed world and linked to many poor health outcomes. Elevated urinary Na may lead to hypercalciuria and an increase in urinary stone risk. Our study aimed to assess the impact of targeted dietary counseling, and its effect on normalizing urinary Na levels in hypercalciuric stone patients.
Methods
A retrospective analysis of a prospectively collected metabolic stone clinic database was performed. Patients with hypercalciuria and elevated urine Na on 24-hour urine collection (24-HUC) were counselled by the attending nephrologist, urologist or a registered dietician to limit their intake of dietary Na to < 2g/day in addition to receiving general dietary advice. Repeat metabolic testing was performed at least 6 months later. Logistic regression was used to determine correlations between elevated urinary Ca and Na to other urinary abnormalities and to evaluate the effect of normalizing urinary Na on other urinary parameters.
Results
Metabolic evaluations from 1184 patients were analyzed. The ninety-eight patients with concomitant hypercalciuria and hypernatriuria were predominantly male (67.3%) and had a higher median BMI than the entire cohort. The presence of elevated urinary Na was also associated with hyperuricosuria (p < 0.001) and hyperphosphaturia (p < 0.001). In follow-up, 59.4% corrected their urinary Na, and 43.8% also had their urinary Ca corrected. Patients who corrected their urinary Na were also more likely to have normal urinary values for volume (p = 0.045), oxalate (p = 0.004), and urate (p = 0.008).
Conclusions
Targeted dietary counseling can be effective in normalizing both elevated urinary Na and Ca levels in stone patients and may obviate the need for pharmacotherapy for the treatment of hypercalciuria in some patients.

Authors: Zeng Li , Zhang Xiangeng , Liu Dong , Li lan , Jin Man , Li Xin , Wang Jialin
Published: May 2023

Background
Nurses' secondary traumatic stress, compassion satisfaction and posttraumatic growth are closely related, but for newly graduated nurses, there are few reports to evaluate the specific path between these three. The aim of this study was to investigate examine the mediating role of compassion satisfaction in secondary traumatic stress and posttraumatic growth among newly graduated nurses.
Methods
From March 2021 to May 2021, a total of 330 newly graduated nurses from five tertiary hospitals in China were enrolled, and asked to complete questionnaires regarding secondary traumatic stress, compassion satisfaction and posttraumatic growth. Descriptive statistics, independent-samples T-test, one-way analysis of variance (ANOVA), Pearson correlation analysis and structural equation model were used in this study. A STROBE checklist was used to report findings.
Results
The scores of secondary traumatic stress, compassion satisfaction and posttraumatic growth of newly graduated nurses were 27.11 ± 4.94, 31.89 ± 6.22 and 56.47 ± 20.41, respectively. Additionally, structural equation modeling showed that compassion satisfaction mediated the relationship between secondary traumatic stress and posttraumatic growth with the partial mediating effect of 0.089.
Conclusions
Newly graduated nurses may experience moderate secondary traumatic stress, but their posttraumatic growth is at a low level, and compassion satisfaction significantly affects the relationship between the two. Nursing managers should strengthen psychological evaluation, and promote their posttraumatic growth by improving their level of compassion satisfaction.
The urinary metabolites of volatile organic compounds and asthma in young children: NHANES 2011-2018
Authors: Xiong Yixiao , Li Tao
Published: May 2023

Background: Volatile organic compounds (VOCs) are synthetic chemicals that are broadly used in the production of numerous day-to-day products for residential and commercial-based applications. Evidence evaluating the prospective association between volatile organic compounds (VOCs) exposure and asthma in the U.S. children is limited. This study aimed to explore the associations between metabolites of VOCs (mVOCs) in urine, a representative of the internal exposure level of VOCs, and childhood asthma.
Methods:We conducted the cross-sectional analysis in 1559 children aged 3-12 years who participated in the National Health and Nutrition Examination Survey (NHANES) 2011-2018. In this study, we investigated the relationship between childhood asthma and urinary concentrations of five volatile organic compound metabolites, including N-Acetyl-S-(2-carboxyethyl)-L-cysteine (CEMA), N-Acetyl-S-(3-hydroxypropyl)-L-cysteine (3HPMA), N-Acetyl-S-(3-hydroxypropyl-1-methyl)-L-cysteine (HPMMA), N-Acetyl-S-(benzyl)-L-cysteine (SBMA) and 2-Methylhippuric acid (2MHA). These metabolites correspond to the parent compounds acrolein, crotonaldehyde, toluene and xylene, respectively. Adjusted logistic regression models were used to assess the relationship between mVOCs and childhood asthma, followed by a stratified analysis.
Results: Urine measurements of mVOCs were weakly associated with an increased odds of childhood asthma, including 2MHA (OR:1.1; 95% CI:0.8, 1.6), SBMA (OR:1.2; 95% CI:0.8, 1.7), CEMA (OR:1.1; 95% CI:0.6, 1.7), 3HPMA (OR:1.1; 95% CI:0.7, 1.8), and HPMMA (OR:1.2; 95% CI:0.7, 2.0). Among female children, 2MHA in urine was significantly associated with the prevalence of asthma (OR: 1.8 95% CI: 1.1, 3.1)). Gender modified associations between urinary 2MHA, but not other urinary mVOCs concentrations, and odds of childhood asthma (gender x 2MHA interaction term p-value = 0.02). Age and race/ethnicity did not modify these associations.
Conclusion: We observed some evidence that urinary mVOCs concentrations are associated with increased asthma prevalence in US children, especially urinary 2MHA is significantly associated with the prevalence of asthma in female children. Further studies are needed to fully understand the potential role of VOCs in childhood asthma

Published: May 2023

For a wide range of people, including malnourished adults with non-communicable diseases (NCDs), micronutrient deficiency, underweight and overweight people, pregnant and lactating women, and adolescents, the current research aimed to present innovative nutraceutical formulations devoted to improving the quality of life (QoL) while promoting health. The novel nutraceutical formulations were structured on a scientific basis with evidence-based health benefits, with daily values (DVs) according to the Food and Drug Administration (FDA), containing a high-quality whey protein concentrate (WPC 70%), skim milk powder (SMP 34%), vitamins (folic acid, B12, C), minerals (iron, zinc), natural flavors (vanilla, cinnamon, coffee, chocolate), and stevia leaf extract sweetener. The novel formulations were subjected to the physicochemical, microbiological, and sensory evaluation. The results showed significant differences (P < 0.05) among formulations with natural flavors added in different amounts to provide 10 g of protein (20% DV), elemental iron and zinc, vitamin C, folic acid, and vitamin B12 (25% DV), with elemental calcium (20% DV) emerged from milk derivatives. The serving sizes of the four formulas were different according to the difference in the amount of natural flavor while keeping the same amounts of the other ingredients. Following the chocolate-flavored formulation as the first in order of overall acceptability, were coffee, cinnamon, and vanilla-flavored formulation, according to the sensory evaluation.

Published: May 2023

Rock types are the reservoir's most essential properties and show special facies with a defined range of porosity and permeability. This study used the fuzzy c-means clustering technique to identify rock types in 280 core samples obtained from one of the wells drilled in the Asmari reservoir located in the Mansouri field. Four hydraulic flow units were determined for studied data after classifying the flow zone index with histogram analysis, normal probability analysis, and the sum of square error methods. Then the two methods of flow zone index and fuzzy c-means clustering were used to determine the rock types in given wells according to the results obtained from the implementation of these two methods in-depth, and continuity index acts, the fuzzy c-means methods with continuity number 3.12 compared to flow zone index with continuity number 2.77 shows more continuity in depth. Amounts of porosity and permeability of the different reservoir rock samples have high dispersion; the relationship between these two parameters improves by using hydraulic flow unit techniques significantly. In this study, the relationship between porosity and permeability of correlation coefficient improves and increases in each hydraulic flow unit by using the flow zone index method so that in the general case for all samples increased from 0.55 to 0.81 in the first hydraulic flow unit, 0.94 in the second hydraulic flow unit, 0.85 in the third hydraulic flow unit and 0.94 in the fourth hydraulic flow unit that this is because the samples were characterized by similar flow properties in a hydraulic flow unit. In comparison, the correlation coefficient is obtained less than the general case in the fuzzy c-means method in all hydraulic flow units.
Effect of stacking position on drying rate during radio-frequency vacuum combined with mechanical press drying of Douglas-fir and Radiata pine
Authors: Lee Changjin
Published: May 2023

In this study, the effect of stacking position in the chamber on the drying rate during radio-frequency vacuum combined with mechanical press (RF/VP) drying was investigated for Douglas-fir and Radiata pine. Drying test was performed at a temperature of 40°C using RF/VP dryer with approximately 3m³. The results showed that the stacking position has a significant effect on the drying rate, with a more pronounced decrease in drying rate as the number of layers increases. Moisture content (MC) on day n-1 was important factor in determining the drying rate in both species. The MC distribution of specimens in the chamber before drying was very irregular, but over time, specimens stacked on the RF charge plate side in the chamber tended to have lower MC distributions than those stacked on the ground plate side, which was serious at the layer-10. In addition, as the MC decreases below the fiber saturation point during RF/VP drying, the difference in MC according to the stacking position became more prominent. These findings provide new insights into the effect of wood dielectric properties on drying rate and are expected to improve RF/VP drying technology.
Dynamics of a Two Species Model with Holling Type III Functional Response and Harvesting using Trapezoidal Fuzzy Numbers [TFN]
Authors: P.Vinothini  , K.Kavitha
Published: May 2023

Fuzzy dynamical modeling plays a major role in various fields, especially in biology. In our paper, we can formulate two species models with Holling type III functional response and harvesting as trapezoidal fuzzy numbers. Boundedness and positivity are found using a dynamic system. The existence of equilibrium points is existing in both crisp and fuzzy forms. Additionally, the parameters were defuzzed using a Graded Mean Value approach, and the dynamical system was reduced at various pessimistic levels. Equilibrium points and stability analysis are determined using a variational matrix in both crisp and fuzzy environments. Numerical simulations are carried out using MATLAB software.

Systematic analysis of crystalline phases in bosonic lattice models with algebraically decaying density-density interactions
Authors: Koziol Jan Alexander , Duft Antonia , Morigi Giovanna , Schmidt Kai P.
Published: May 2023

We propose a general approach to analyse diagonal ordering patterns in bosonic lattice models with algebraically decaying density-density interactions on arbitrary lattices. The key idea is a systematic search for the energetically best order on all unit cells of the lattice up to a given extent. Using resummed couplings we evaluate the energy of the ordering patterns in the thermodynamic limit using finite unit cells. We apply the proposed approach to the atomic limit of the extended Bose-Hubbard model on the triangular lattice at fillings f=1/2f=1/2 and f=1f=1. We investigate the ground-state properties of the antiferromagnetic long-range Ising model on the triangular lattice and determine a six-fold degenerate plain-stripe phase to be the ground state for finite decay exponents. We also probe the classical limit of the Fendley-Sengupta-Sachdev model describing Rydberg atom arrays. We focus on arrangements where the atoms are placed on the sites or links of the Kagome lattice. Our method provides a general framework to treat cristalline structures resulting from long-range interactions.
Unintended transnationalism of Ukrainian military migrants in Poland: Socio-cultural aspect
Authors: Burliai Alina , Demianchuk Maryna , Burliai Oleksandr
Published: May 2023

The full-scale military invasion of Ukraine by the Russian Federation in 2022 triggered a massive wave of forced migration to Poland. This has resulted in the phenomenon of ‘unintended transnationalism.’ Transnational migrants do not part with their country of origin forever but live a double life, act as members of two socio-cultural communities and become carriers of a double culture. This study aims to systematize the socio-cultural peculiarities of the unintended transnationalism of military migrants from Ukraine to Poland.The theoretical foundations of migrants’ transnationalism are systematically analyzed and its main characteristics are systematized. The emergence of the so-called unintentional transnationalism of military migrants is revealed. A comparative analysis made it possible to compare transnational processes in Poland and Ukraine. The study found that migrants’ transnationalism is manifested through sharing their cultural values, traditions, and customs in a new cultural environment. The culture of migrants includes elements of the host country’s culture, elements of the culture of the migrants’ homeland, as well as new elements arising from the interaction of these two cultures. The main manifestations of migrants’ culture are language and communication, education, religious practices, intercultural dialogue, relations between representatives of different cultures, and other aspects of their daily lives. The study has shown that the transnationalism of military migrants can generate various cultural processes, including multilingualism, hybridization, cultural diffusion, cultural preservation, and intercultural dialogue.
DISTRIBUTION OF THE FRENCH COORDINATION DONC IN DIACHRONY
Authors: Auseichyk Yulia V. ,   Minsk State Linguistic University
Published: May 2023

The work is devoted to the development of the distributive properties of the French polyfunctional item donc ‘therefore, so’ in a broad diachronic perspective, from the 11th century to the present. As a result of accessing the data of the National Corpus of the French language Frantext and the French corpus of the Google books Ngram Viewer system, the trajectory of the development of donc as a coordinator is determined. It is concluded that the long-term variability of the donc written forms, which differ in distributive properties in texts of different genres, leads to multidirectional trends in its use as a coordinator. As a result of comparing the contexts in which donc shows its conjunctive properties and establishes the logical-semantic relations of the consequence, the following is established. The share of donc usage as a coordination unit of two independent sentences in the initial position has been significantly reduced over more than a thousand years of the French language development. This way of donc use is not predominant. The use of donc in the postposition to the personal form of the verb to establish a connection, with the exception of the imperative mood, tends to gradually increase. The donc use in cooccurrence with other coordinating conjunctions (et donc, ou donc, mais donc, etc.) is a special case of it’s functioning. The results obtained complement the previous scientific knowledge about the functioning and syntactic mobility of donc and are necessary for comparison with information of this kind about other linking words.

Published: May 2023

Game is an important cultural phenomenon, whose impact on social life and personal development cannot be overestimated. The topic of the game is the basis for the plot and problem formation in many fiction works. The article aims to identify and analyse the structure of the concept-sphere “game” in texts by American writers who reflected this phenomenon in their works. The research tasks are to reveal the micro-contexts referring to the game and to describe the nucleus, the co-nuclear area, the near periphery and the further periphery of the concept-sphere. This article is the first to examine the cognitive- propositional structure of the concept-sphere “game” in the texts under analysis. As a result the analysis of each constituent of the concept-sphere is conducted. The nucleus is presented by the cognitive-propositional structure, including the subject, the predicate, the reason, the purpose, the result, the consequence and the locative of the game. The co-nuclear zone is formed by lexical representations, revealing the contents of the above-mentioned components. The near periphery includes artistic images of the game. The further periphery reflects social and cultural aspects of the game and the personal attitude of the characters to this phenomenon. The research combines linguistic and literary approaches. The basic method is conceptual analysis, a combination of various techniques used to analyse concepts. The descriptive method and the method of contextual analysis are also applied. The latter enables to investigate the concept-sphere “game” on all levels of the text structure as well as to consider the message of the analysed works.
VISUAL PERCEPTION ACTS: SOME ASPECTS OF LINGUISTIC REPRESENTATION IN LANGUAGES WITH DIFFERENT CODING STRATEGIES OF CHARACTERIZATION SEMES

Published: May 2023

This article deals with the description of the specifics of representing the semantic field of visual perception by English, German, French and Russian verb lexemes. The emphasis is on “basic” lexemes, those ones that denote the ability to perceive information visually without having the intentionality component in their semantic structure. These verb lexemes are “see,” “sehen,” “voir,” and “видеть.” Their semantic structure consists of two components: “visual perception” and “ability.” In German, a third component, “intentionality,” can also be activated, although, it changes the lexeme’s status, because it is the absence of the “intentionality” component that distinguishes the “basic” verbal predicates of visual perception from a large group of other lexemes in which this component is mandatory. In verbs like “look,” “regarder,” “watch” and others it occupies one of the central places in the seme structure of the word. This ability to have such a component can be presented implicitly or explicitly, depending on various factors, including the linguistic tradition.

One of the topical areas of study of modern Russian sociolinguistics is the theory of language activism, which, as a rule, correlates with the activities oriented towards languages that are not supported de jure or are not efficiently supported de facto to maintain their functioning in various areas of communication. The article discusses approaches to the definition of the concept of language activism, analyzes the prerequisites for the emergence of the language activism in the Russian Federation and the forms of its existence. In this analysis, the author relies on the field sociolinguistic research conducted within the period of 2021–2022 on the territory of the Republic of Tyva and Sakha (Yakutia).
PRAGMATEMES IN THE SITUATION OF EDUCATIONAL BILINGUALISM
Authors: Kayumova Albina R. ,   Kazan (Volga Region) Federal University, Pakhomova Elizaveta G. ,   Kazan (Volga Region) Federal University
Published: May 2023

The article focuses on the peculiarities of understanding and translating pragmatemes in the situation of educational bilingualism. We conducted a questionnaire [Pragmatemes] among 37 1–4 year students of the Bachelor Programme Philology: English Language and Literature, Translation Studies in order to find out students’ knowledge of English pragmatemes. The results of the analysis of the questionnaire show that in most cases students, when translating a pragmateme, choose a false literal counterpart; they lack knowledge about synonymous pragmatemes and their communicative register. In addition, comprehension and usage of pragmatemes becomes more complicated if they reflect national or cultural specifics. The results of the research indicate that students find it difficult to choose an adequate translation of pragmatemes and recognize their semantic, stylistic and semantic-stylistic features. Students become hostages of both purely linguistic and linguistic-cultural interference. Therefore, it is necessary to pay more attention to the study of pragmatemes in the situation of educational bilingualism.

Authors: Mikhalkova Nadezhda V. ,   Minsk State Linguistic University
Published: May 2023

Motivational features that determine the choice of the main semantic component of complex Chinese characters with object semantics are established and described in this article. The analysis of the determinatives that are included in multicomponent characters of various semantic types (nominations of clothing, transport, furniture, weapons, containers, etc.) made it possible to reveal their frequency regarding of different thematic relevance. The material of the study based on the group of compound characters (structurally including from two graphemes in a sign, one of which is a determinative), denoting object names selected according to the principles of classification of lexical units, undertaken when compiling the semantic dictionary ed. N. Yu. Shvedova, dissertation research by M. I. Oleinik, as well as the described classes of object nouns (物品类名词) in the study of Zhang Daoxin, Zhang Jiahua. The total volume of the analyzed characters with object semantics amounted to 967 units. The analysis of the selected signs showed that the choice of the determinative of the complex Chinese character with object semantics is based on the relevance of the material as the most significant historically or functionally characteristic of the described representation of objects that are spatially limited, can be identified and counted. The evolution and development of the basic graphemes of Chinese writing determine, at the same time, the relevance of such motivational features as category, form and object, as well as their different frequency within different semantic groups of complex signs with object semantics.
HOW LEXICAL MEANS OF GRADUATION CONTRIBUTE TO EVALUATION IN RUSSIAN AN GERMAN SCIENTIFIC TEACHING PRACTICE
Authors: Stepanov Evgenii S. ,   St. Petersburg State University
Published: May 2023

The present article examines evaluation strategies in scientific teaching practice and focuses on graduation as an evaluative tool. Graduation is thought of as an additional qualificative meaning which is superimposed on the main evaluation component and aims at intensifying or down-toning the degree of author’s intent. The textual analysis is carried out within the framework of the theory of communication practices. It allows to distinguish the text type of university textbook which is a basis for the empirical material of the study. The linguistic methodology of the theory of evaluation is chosen to examine the manifestation of evaluative strategies in university textbooks. The analysis of German- and Russian-language textbooks on sociology shows that the use of graduation in the evaluative function is a common evaluation strategy (20 % of all evaluative acts in German-language textbooks and 19 % in Russian-language textbooks). Three groups of graduators are emphasizers, intensifiers, and hedgers. Intensifiers have similar use frequency both in German and Russian scientific teaching practice whereas emphasizers are spread more widely in Russian textbooks. Russian and German authors in scientific teaching practice tend to graduate knowledge according to its relevance emphasizing most important information and intensifying their evaluative judgements. The use of mitigation markers is rather uncommon here since the goal of scientific teaching practice is to provide students with most relevant information.
Hematopoietic stem cells from umbilical cord blood (placenta) as an object of civil rights

Published: May 2023

The article examines the problems of civil law regime of hematopoietic stem cells of umbilical cord (placental) blood. Currently, hematopoietic stem cells of umbilical cord (placental) blood, as well as other human biological objects are not legally classified as objects of civil rights. As part of the study, the author conducted an analysis of hematopoietic stem cells of umbilical cord (placenta) blood in the context of their attribution to civil rights objects, for which they were studied in the refraction of such properties (attributes) of civil rights objects as discreteness, legal binding and consistency. Based on the analysis, it was found that the examined cells correspond to the properties (attributes) of objects of civil rights and therefore can be classified as such. One of the key problems arising in law enforcement is the determination of the owner of these cells. To answer this question, the author has analysed the legal position of the child’s father, the child’s mother and the child himself, taking into account medical advances. It is concluded that both mother and child have rights to these cages and they are subject to the regime of joint ownership. It is argued that the ownership of hematopoietic stem cells arises at the time of isolation of their concentrate from the umbilical cord (placental) blood. Considering the contractual regulation of legal relations in the use of hematopoietic stem cells of umbilical cord (placenta) blood, taking into account that their collection, transportation and storage are types of works (services) constituting medical activities, it is concluded that these activities should be carried out in accordance with Chapter 39 “Gratuitous provision of services” of the Civil Code. In terms of storage of isolated cells, the rules of Chapter 47 “Storage” of the Civil Code of the Russian Federation may be applied subsidiarily.

This article reveals one of the facets of a big topical topic formulated in the form of a radical transition of digitalization of transport engineering in Kazakhstan, to electric mobility, autopilot of its products, which should be disclosed through national and international legal decisions. This approach is expedient, because thanks to it, Kazakhstan’s transport engineering receives accelerated development. The purpose of this article is to conduct a systematic analysis of national and international legal problems of the transformation of today’s transport engineering into a digitalized one, in the production process of which various digital technologies, artificial intelligence technologies, robot manipulators at all production sites, automated mechanisms that allow the production of electric vehicles, autopilot-intelligent vehicles for various purposes will be involved. In this regard, researchers pay special attention to the legislative acts of the Republic of Kazakhstan, legislative acts of developed countries, as well as international conventions and agreements ratified and initiated by the Republic of Kazakhstan on the radical transition to a qualitatively new level of the above-mentioned branches of mechanical engineering, electric mobility and autopilot of transport vehicles produced by it. On this basis, the researchers in this article formulated legislative, organizational-legal, managerial- legal and practical proposals for the real provision of the radical transition of the studied branches of transport engineering through 5G technology. The authors use the method of comparative legal analysis of the legislation of different countries with the transport and production legislation of Kazakhstan. The method of scientific forecasting allows researchers to formulate new Kazakh laws and new international conventions relevant to the analyzed topic. The practical and theoretical significance of the study is related to the improvement of transport production and legal ways of digital export of products of Kazakhstani transport engineering enterprises on the basis of the World Trade Organization law.

The subject of legal science manifests itself as a result of the study of its object by methods suitable for the study of the object. A legal scholar must operate not only with formal legal research methods, but with other methods that allow one to understand the purpose and means of activity of a participant in digital relations, and then also the environment (digital technologies and regulatory frameworks) as an external factor influencing the behavior (will) of participants in digital relationships. These methods imply a difference in the types of human activity and relations, as well as their legal regimes: private and public digital relations and methods of their regulation. From a theoretical point of view, digital law is not a separate subdivision in the legal system, but a digital form of private and public digital relations, which requires new approaches to their regulation, but not replacing the content of digital relations with their form. Private digital relations are the result of legal communication (self-regulation) of participants in digital relations. Public digital relations are not relations of law, but relations of power and subordination (power relations). The constitutional aspects of the legal study of digital relations make it possible to find a balance in matters of state support for the development of digital technologies and ensuring human rights and freedoms in his digital relationship with the state. The digitalization of relations is only one of the means used by society and its public entities for the good of man, as his highest value. The state should not so much regulate technological processes as exercise state control over the activities of technology developers and protect the rights of participants in digital relations.
Enhancing College Students’ Intercultural Competence through International Electronic-Service-Learning
Authors: Weng I-Jane Janet ,   Department of English, Wenzao Ursuline University of Languages, Taiwan
Published: May 2023

International Electronic-Service-Learning (eSL) is regarded as a pedagogical innovation, yet very few research studies focus on it. During COVID-19, seventeen Taiwanese student volunteers joined an international e-service-learning program, taking turns teaching English online for one semester to one year to primary school students in a remote village in Cambodia. This study employed a qualitative case study research design. It analyzed how an eSL program impacted Taiwanese students regarding intercultural communicative competence development. Research data included in-depth interviews, student reflection journals, bi-weekly meeting minutes, voice recordings of final presentations, and teacher’s field journals. Byram’s intercultural communicative competence framework was adopted to code the data and establish learning outcomes. Results found that the college student-volunteers enhanced their intercultural competence; this ranged from understanding real-life situations in Cambodia to empathizing with others, making cultural comparisons, and developing better interaction and communication. Most importantly, it showed that it had the potential to transform the student volunteers into intercultural citizens who began to question the taken-for-granted convention in their own life experiences critically. They became more willing to take responsibility for their own lives and those of the global community.

This study aimed to explore the impact of the LearnEnglish Grammar app on the grammatical accuracy of 10th-grade students at a gifted high school. Utilizing a quasi-experimental design, the researchers randomly assigned students to either an experimental group that used the app for grammar lessons or a control group that received traditional grammar instruction. The results revealed that the LearnEnglish Grammar mobile app significantly enhanced the experimental group’s grammar competence compared to the control group. Most learners demonstrated a positive attitude towards the app and expressed an interest in incorporating it into their language studies. These findings support the comprehensive integration of mobile learning in English grammar education to improve student achievement and lay the groundwork for future research on the effectiveness of mobile learning applications across various school subjects.

In the call for diversity and social justice in language teacher education, it is necessary to explore the identities and pedagogies of LGBTQ+ identified language teacher educators. In this article, we (two teacher educators, one from Chile and the other from the United States), through a testimonio-based duoethnographic study, explored our LGBTQ+ identities and pedagogies, and our experiences in initial teacher education. From our experiences and reflections shared through conversations and writings, we identified themes to envision LGBTQ+ initial teacher education: pedagogies from identities, making visible as LGBTQ+ teacher educators, intersectionality of LGBTQ+ with other issues of oppression, and non-LGBTQ+ allies and teachers. We conclude that initial teacher education must make LGBTQ+ more visible in education and the school curriculum. We further pose an ethical responsibility on LGBTQ+ language teacher educators as agents of change toward achieving social justice. Finally, recommendations for further research on LGBTQ+ language teacher identities are presented.
Manifestation of HIV stigma and stigma-reducing interventions among service providers

Published: May 2023

The stigma associated with HIV/AIDS (H/A) and persons living with H/A (PLWHA) continues to pose significant barriers to accessing services and has a deleterious effect on the quality of care. Lack of H/A knowledge and awareness, cultural beliefs, misinformation, and stigma-enhancing policies have been linked with HIV-related stigma at the service provider level; however, research focusing on provider-level stigma and its effects on PLWHA is scarce. This study aims to address this critical gap in research, specifically in understanding how stigma manifests, what kinds of HIV stigma interventions exist, what best-practices are recommended to reduce HIV stigma and what the impact of service provider stigma is on the community. Study aims were investigated through a systematic literature review using the PRISMA protocol. Findings suggest that HIV-related stigma is still common among health care providers and is the product of a synergistic cooccurrence between deeply held personal beliefs and values. Findings also suggest that this stigma is propagated through lack of training and education on H/A and PLWHA populations, lack of experience, wide-ranging societal stigma, and biased individual views. We recommend an increase in psychosocial trainings for service providers. Practice interventions at the micro, mezzo, and macro levels are also recommended.

Entre Ciberfeminismo e Artivismo: Feminismo em Portugal no Dia Internacional Para a Eliminação da Violência Contra as Mulheres
Authors: Lamartine Camila , Cerqueira Carla
Published: May 2023

A modalidade visual é um recurso imprescindível para as ciberfeministas desde a sua origem. A união entre o artivismo e o movimento feminista visa descolonizar os saberes artísticos e exclusivistas, além de propiciar visibilidade às temáticas das mulheres, especialmente em relação às múltiplas formas de violência de género. Assim, este artigo tem como principal objetivo perceber de que forma as ciberfeministas recorreram ao artivismo feminista para assinalar o Dia Internacional para a Eliminação da Violência contra as Mulheres, em 2021, em Portugal. Recorrendo a análise de conteúdo, observamos as publicações do Instagram de 10 associações e coletivos feministas portugueses no dia 25 de novembro, separando os dados em intervenções online e offline, na constatação de que o ciberfeminismo articula fronteiras que interconectam esses espaços de forma permanente. Destacamos que o artivismo opera no atual movimento feminista português como uma ferramenta estratégica e política para disseminação e propagação do ciberfeminismo.

Cooperative learning has become a fundamental teaching-learning strategy for the social construction of knowledge. This methodology is ideal for students at kindergarten in regions such as Latin America and the Caribbean, where the effects of learning poverty condition socioeconomic development. Therefore, the objective was to evaluate the incidence of cooperative learning in the teaching of geometry in 5-year-old students belonging to educational institutions of the kindergarten in the three natural regions of Peru. This was qualitative, descriptive-correlational research. Two data collection instruments were applied to 78 students who served as a sample. To analyze the relationship between the variables, Spearman's Rank-Order was used, which confirmed the positive relationship between them; therefore, the influence of incorporating this type of learning does have an impact on the logical development of children. Quality education with optimal learning strategies will lead these students in the future to a good level of performance in academic tests such as PISA.

A good sport learning planning could minimize injury risk in sports learning. The study aimed at finding out the preparation process of sport learning planning and the number of injury cases. It used a cross-sectional design with a quantitative approach. It was conducted in April-October 2022 at junior high schools in the Special District of Yogyakarta. Its samples were drawn from 20,401 students and 33 physical, sports, and health education teachers using a random sampling technique that gave 400 samples (171 males and 229 females). The validity test of the student questionnaire gave r-count r-table (0.235) and alpha Cronbach of 0.928 0.655, while the validity test of the teacher questionnaire gave r-count r-table (0.344) and alpha Cronbach of 0.737 0.655. Results: There were 158 students (39.50%) who got cervical vertebrae injuries, 193 students (48.25%) who got shoulder injuries, 133 students (33.25%) who got elbow injuries, 182 students (45.50%) who got wrist injuries, 163 students (40.75%) who got finger injury, 198 students (49.50%) who got waist injury, 170 students (42.50%) who got pelvis injury, 202 students (50.50%) who got knee injury, 170 students (42.50%) who got ankle injury, and 165 students (41.25%) who got toe injury. Concerning sports learning planning, there were 2 teachers (6.1%) who never planned sports learning, 8 teachers (24.2%) who rarely planned it, 13 teachers (39.4%) who occasionally planned it, 9 teachers (27.3%) who often planned, and 1 teacher (3.0%) who always planned it. Conclusion: Knee injury was the most common one and teachers have not well-planned sport learning. It was necessary to conduct further study of the correlation between sports learning planning and the injury

The objective of this research is to examine senior high school students’ perception in Indonesia in defining physical education teachers’ competence. The research used a qualitative method and metaphor analysis concept. The metaphor concept was used to collect and analyze the data. The data were collected from questionnaire with the question “How are my physical education teachers …?” The respondents were totally 237 students in Indonesia who were chosen randomly based on their willingness to fill in the questionnaire prepared. The results show the frequently used words as follows: ‘kind’, ‘cool’, ‘cheerful’, ‘friendly’, and ‘firm’. The other results show some words with negative meaning, including: 'infrequently present', 'annoying', 'difficult', and 'fierce'. The term 'ex' shows non-professional competence. This research finds that the Physical Education teachers were kind, friendly, and patient in delivering lesson passionately and with fun and showed discipline, showing that they had the four core competences. However, the negative words appearing limitedly in the questionnaire still require more attention.
