System interface of scientific services of a digital platform for multiscale modeling
Authors: Kondrashev V. A. , Denisov S. A.
Published: August 2023

The paper deals with the formation of system interfaces of a digital platform for managing the process of providing scientific services, including the integration of scientific services for solving a complex research problem, for example, multiscale modeling of the properties of new materials or conducting interdisciplinary research. On the basis of the functional structure of the integration of scientific services of a digital platform (in relation to multiscale modeling) presented in the work, requirements for the system interface are formulated, and the architecture of the system interface for the integration of scientific services of a digital platform is proposed. The proposed model of a system interface for information interaction with services and datasets of a digital platform in management processes for the provision of scientific services is based on modern solutions for managing virtual infrastructure, based on container processing technologies and microservices, as well as container orchestration and communication (service mesh), flexible technologies (agile) integration. Taking into account that the main function of the digital platform is to provide processes for the preparation and conduct of research by formalizing the interaction scenarios of researchers, suppliers (sources) of initial data, consumers of the results, along with tools for supporting system interfaces to the catalogs of the digital platform, the project offers means for organizing the interaction of services, registered on the platform in order to ensure the execution of scientific research. Synchronization of the processes of providing services, ensuring the transfer of data between services and obtaining the final result are also ensured by implementing the control processes of the digital platform, which is based on the proposed system interface. The developed model of system interfaces is new in the work. The proposed interaction interface allows you to effectively consolidate high-performance computing resources and mathematical models based on digital platform technologies. This is especially important for organizing the solution of multiscale modeling problems as a complex of models, each of which operates on the same space-time scale.

Authors: Uvarova O. V. , Uvarov S. I.
Published: August 2023

In the process of modeling multilayer semiconductor nanostructures, it is important to quickly obtain accurate values the characteristics of the structure under consideration. One of these characteristics is the value of the interaction energy of atoms within the structure. The energy value is also important for obtaining other quantities, such as bulk modulus of the structure, shear modulus etc. The paper considers a machine learning based method for obtaining the interaction energy of two atoms. A model built on the basis of the Gaussian Approximation Potential (GAP) is trained on a previously prepared sample and allows predicting the energy values of atom pairs for test data. The values of the coordinates of the interacting atoms, the distance between the atoms, the value of the lattice constant of the structure, an indication of the type of interacting atoms, and also the value describing the environment of the atoms were used as features. The coordinates of the atoms, the distance between the atoms, the lattice constant of the structure, an indication of the type of interacting atoms, the value describing the environment of the atoms were used as features. The computational experiment was carried out with structures of Si, Ge and C. There were estimated the rate of obtaining the energy of interacting atoms and the accuracy of the obtained value. The characteristics of speed and accuracy were compared with the characteristics that were achieved using the many-particle interatomic potential — the Tersoff potential.

Published: August 2023

This paper presents the a study about the emission of greenhouse gases - GHG resulting from the final disposal of urban solid waste - USW in the State of Pará. The research was qualitative and quantitative, applied in nature and with exploratory and descriptive objectives, having as object of study the solid waste sector in the State of Pará. The activities carried out were divided into 3 stages, with the verification of the amount of GHG emissions in the State of Pará (Stage 1), the contribution of the sectors responsible for the state's emissions (Stage 2) and the analysis of GHG emissions in the USW sector (Stage 3). The survey results show that Pará is the state that emits the most GHG in Brazil (447,927,368 tons of CO2e). Although the USW sector accounts for only 1% of GHG, it was found that 138 of the 144 municipalities in Pará still send USW to dumps and controlled landfills. With the research, it was verified the need to adapt the environmentally-appropriate final destination of USW, as an alternative to reduce GHG emissions in the State of Pará.

los gestos no políticos son políticos: la traducción al portugués del Brasil de Giovanni's Room, de James Baldwin, y la cuestión de la homosexualidad
Authors: Amorim Lauro
Published: August 2023

Este trabajo hace parte de un proyecto de investigación sobre el papel de las traducciones de literatura afro-americana en el Brasil y su relación con cuestiones de identidad, discurso y estética. Se analiza la traducción que hace Affonso Blacheyre de la novela Giovanni's room (1956) de James Baldwin, publicada en 1967. Baldwin es aclamado por su participación en el Movimiento por los Derechos Civiles, habiendo producido trabajos que retratan las contradicciones de una sociedad democrática y al mismo tiempo racista. Giovanni's room fue rechazado por su editora por abordar la homosexualidad. El texto publicado en la solapa de la carátula del libro  elogia el trabajo de Baldwin con el "lenguaje", en contraste con el anti-racismo de muchos otros de sus trabajos. El elogio concerniente a la estética de Giovanni's room es notorio,  en contraste con la ausencia de comentarios sobre su crítica de la marginalización de la homosexualidad. El enfoque en la estética del trabajo llevó incluso a una sofisticación del registro del habla de los personajes en la traducción. Los discursos en torno a la formación de identidades eran menos evidentes en el Brasil de los años 60 en comparación con la actualidad. El énfasis en la naturaleza estética de la obra representa un gesto aparentemente "no-político", menos chocante en el contexto de la dictadura militar vivida en el país en la época.

Authors: Pérez Juan Pedro
Published: August 2023

Tras su llegada a las costas de Brasil en 1553, el misionero jesuita y humanista José de Anchieta ejerció de arquitecto, médico, ingeniero, maestro, intérprete, lingüista, dramaturgo y poeta, además de proteger y atender a las comunidades indígenas y ser cofundador de diversas ciudades, entre ellas la de São Paulo en 1554. Cuatrocientos años después, el compositor brasileño Heitor Villa-Lobos escribe su sinfonía nº 10 “Amerindia”, en la que incluye algunos versos de Anchieta extraídos de su poema De Beata Virgine Dei Matre Maria, que sirvieron para conmemorar el IV centenario del nacimiento de São Paulo y como homenaje al poeta y taumaturgo tinerfeño.
Classification of Myopathy and Normal Electromyogram (EMG) Data with a New Deep Learning Architecture
Authors: TUNCER Erdem , DOĞRU BOLAT Emine
Published: August 2023

Electromyograms (EMG) are recorded movements of nerves and muscles that help diagnose muscles and nerve-related disorders. It is frequently used in the diagnosis of neuromuscular diseases such as myopathy, which causes many changes in EMG signal properties. The most useful auxiliary test in the diagnosis of myopathy is EMG. Therefore, it has become imperative to identify computer-assisted anomalies with full accuracy and to develop an efficient classifier. In this study, a new machine learning method with a deep learning architecture that can score normal and myopathy EMG from the EMGLAB database is proposed. Using the discrete wavelet transform Coiflets 5 (Coif 5) wavelet, the EMG signals are decomposed into subbands and various statistical features are obtained from the wavelet coefficients. The success rates of the decision tree C4.5 algorithm, which is one of the traditional learning architectures, and the Long Short-term Memory (LSTM) algorithm, which is one of the deep learning architectures, were compared. Unlike the studies in the literature, with the LSTM algorithm, a 100% success rate was achieved with the proposed model. In addition, a real-time approach is presented by analyzing the test data classification time of the model.

Published: August 2023

Wireless sensor networks (WSNs) are widely used in various fields, and their deployment is critical to ensure area coverage and full network connectivity to achieve the maximum network lifetime. In this study, we present a mixed-integer programming (MIP) model that deeply investigates deployment parameters to optimize lifetime and analyze network connectivity. We further analyze the obtained results using Deep Belief Network (DBN) and Deep Neural Network (DNN) algorithms to achieve higher accuracy rates. Our evaluation shows that the DBN outperforms the DNN with an accuracy rate of 81.2%, precision of 81.2%, recall of 99.1%, and an F1-Score of 0.78. We also utilize two different datasets to justify the efficiency of the DBN in this research. The findings of this study emphasize the validity of our DBN algorithm and encourage further research into lifetime optimization and connectivity analysis in WSNs.

Published: August 2023

This paperconsidersthe applicationfeatures of Federal Law No. 223-FZ by organizations that fall under its action. Since its entry into force, this Federal Law has undergone many changes and additions, which, on the one hand, is an advantage and leads to an improvement in the law, but on the other hand, this leads to a complication of the procedure for its implementation, due to the emergence of additional requirements for customers that fall under the regulation of this law. The paperalso discussesthe importance and necessity of introducing electronic document management in the organization, which in turn will lead to the convenience of work in the field of procurement and the exclusion of the human factor. One of the most significant elements of the proper organization of an electronic document management system is the development of the necessary databases, which include a diversity ofinformation, but at the same time theyare easily consistent with each other. Possible design methods and ways to automate the procurement process are considered. Methods for creating an information system are proposed, which include the entire complex of processes related to procurement activities, using the Structured Query Language (SQL), which is used to develop databases and organize work with them

Exploring teachers’ perceptions towards dialogic teaching in primary science classrooms in Saudi Arabia
Authors: Alharbi Alruways , Johnston-Wilder Sue
Published: August 2023

This purpose of this study was to investigate teachers’ perceptions of the implementation of the dialogic teaching approach in primary science classrooms in Saudi Arabia. Semi-structured interviews were conducted with 12 primary school science teachers to collect the qualitative data. The interviews were video recorded, and the collected data were analyzed using NVivo software. The majority of primary science teachers demonstrated positive attitudes towards the use of dialogic teaching in science lessons, citing a number of associated advantages of dialogic teaching such as supporting students' learning, attracting students' attention, creating a positive learning environment, developing students' characteristics and developing a culture of dialogue in the classroom. However, despite employing a number of dialogue activities including teacher-student dialogue, student-student dialogue, question and answer, group discussion, and teacher-led class discussion, the results indicated that the teachers tended to control the use of dialogue, due to the challenges they encounter in their teaching practice. This paper discusses the implications of six main challenges identified as hindering dialogic teaching, related to: teachers; students; schools; class sizes; the science curriculum; and lack of time. Accordingly, a number of suggestions were concluded that could address the challenges and improve the quality of the implementation of the dialogic teaching approach in Saudi schools.
Platelet-Rich Plasma Intrauterine Infusion as Assisted Reproduction Technology (ART) to Combat Repeated Implantation Failure (RIF): A Systematic Review and Meta-Analysis
Authors: Huang Chunling , Ye Xiaohui , Ye Lifang , Lu Lunyuan , Liu Fengxiang
Published: August 2023

Background: Repeated implantation failure (RIF) is considered one of the major challenges facing clinician in assisted reproduction technologies (ART) despite the significant advances that have been made in this field. Platelet rich plasma (PRP), also known as autologous conditioned plasma, is a protein concentrate with anti-inflammatory and pro-regenerative characteristics. The use of PRP in women undergoing ART has been studied in the past, with varying degrees of success. The goal of this trial was to see if injecting PRP into the uterus improves pregnancy outcomes in women receiving ART.
Methods: PubMed, Embase, Scopus, Web of Science, and the Cochrane Database of Clinical Trials were among the databases searched (CENTRAL), from 2015 to 2021. The pooled estimates were calculated using a meta-analysis with a random-effects model. There were 14 studies with a total of 1081 individuals (549 cases and 532 controls).
Results: There was no difference in miscarriage rates between women who got PRP and those who received placebo (P≤0.90). Chemical pregnancy (P≤0.00), clinical pregnancy (P ≤0.001), and implantation rate (P≤ 0.001) were all significantly higher in women. Endometrial thickness increased in women who got PRP vs women who received placebo after the intervention (P ≤0.001).
Conclusion: PRP may be an alternate therapeutic approach for individuals with thin endometrium and RIF, according to the findings of this comprehensive study. To determine the subgroup that would benefit the most from PRP, more prospective, big, and high-quality randomized controlled trials (RCTs) are needed.

Published: August 2023

Over the last decade, we were facing medical struggle by the emergence of multi-resistant bacteria, especially methicillin-resistant Staphylococcus aureus (MRSA). MRSA infections are still causing a growing global concern due to the rapid adaptive multidrug resistance to conventional antibiotics in human, community and veterinary medicine. Here we provide an overview about MRSA epidemiology, transmission and alternative potential treatments particularly new discovered phytochemicals with biological activity. In this narrative review, bibliographic data was collected from literature search databases: Google Scholar, web of science and PubMed/MEDLINE during recent years (2016 to 2021). MRSA is responsible of wide spectrum life threatening infections such us septicemia, endocarditis, and wound infections. It has epidemic potential in hospitals, that is responsible of most nosocomial infections leading to mortality and constitute a real burden for the healthcare systems. Effective preventive strategies for management of MRSA are highly required moreover, the identification and development of novel drugs or active biomolecules through phytochemicals are time challenging to face new resistant strains.

Published: August 2023

Background: Non-alcoholic fatty liver disease (NAFLD) is the world's most common etiology of chronic liver disease. In this systematic review and meta-analysis, we estimated the prevalence of NAFLD in the Iranian children and adult population.
Methods: A comprehensive search of five international databases, including PubMed, ISI/WOS, ProQuest, Scopus, and Google Scholar, was done from inception to Nov 2022. Studies on NAFLD patients and their risk factors were selected for meta-analysis. The quality of the included studies was assessed by The Joanna Briggs Institute (JBI) Critical Appraisal Checklist for cross-sectional, and cohort studies. The heterogeneity between studies was investigated using Cochran test and I2 statistics. Random and fixed effect models were used for heterogenic and non-heterogenic studies, respectively. We used Comprehensive Meta-Analysis version 3 for conducting meta-analysis.
Results: Twenty studies were finally included. The total prevalence of NAFLD in children, boys, and girls was 6.7% (95% CI: 0.02-0.18), 12.5% (95% CI: 0.04-0.29) and, 10.1% (95% CI: 0.04-0.21), respectively. The total prevalence of NAFLD in obese children, obese boys, and obese girls was 42% (95% CI: 0.18-0.69), 44% (95% CI: 0.13-0.80), and 33 % (95% CI: 0.13-0.62), respectively. The total prevalence of NAFLD in adults was 36.9% (95% CI: 0.31-0.42). The prevalence of NAFLD in men and women was 33.8% (95% CI: 0.27-0.41) and 29.9% (95% CI: 0.21-0.40), respectively.
Conclusion: NAFLD prevalence in Iranian adults and obese children is considerable; however, data about the children population was insufficient.

Authors: Someah Mirghani Seyed , Golbabaei Farideh , Arjomandi Reza , Semiromi Farzam Babaei , Mohammadi Ali
Published: August 2023

Background: Asbestos is one of the most important environmental and occupational carcinogens. Nevertheless, the mechanisms by which asbestos fiber exposure causes chronic diseases are not fully understood. We performed the first systematic review on the epidemiological evidence to examine the association between occupational exposure to asbestos and oxidative stress and DNA damage.
Methods: In this systematic review study, the PubMed and Scopus databases were searched for English-language publications. Eleven cross-sectional studies were included in the systematic review. A literature search was conducted by the main keywords including "Asbestos", "crocidolite", "chrysotile", "amphibole", "amosite", "Oxidative Stress", "DNA Damage", and "DNA injury". To evaluate the quality of studies, the "Newcastle-Ottawa Quality Assessment Scale" (NOS) was used.
Results: Overall, 1235 articles were achieved by searching in databases. Finally, by considering the inclusion, and exclusion criteria, 11 articles were conducted for this study. These studies were published between 1986 and 2020. Oxidative stress and DNA damage can occur in exposure to asbestos. Among various biomarkers, 8-OHdG is the best. The analysis of 8-oxodG in asbestos workers can help identify subjects with a higher level of genotoxic damage.
Conclusion: This systematic review suggests that oxidative stress and DNA damage are two main outputs of asbestos exposure. Therefore, oxidative stress and DNA damage biomarkers can be used for identifying subjects at higher risk of cancer. These findings support policy initiatives aimed at detecting and eliminating asbestos fiber exposure and preventing potential health hazards in occupational settings.

Published: August 2023

Background: Scant information exists on Iranian women's protective behaviors mainly constant condom use. Inconsistent condom use seems prevalent among women with substance use problems. We aimed to investigate risky sexual behaviors (RSBs) and condom use barriers in Iranian women with substance use disorders (SUDs).
Methods: In our cross-sectional study, we recruited 300 women who sought treatments for their SUDs from the active outpatient drug free (ODF) and Methadone Maintenance Therapy (MMT) centers in Tehran, Iran during 2017-2021. We used three batteries including demographic questionnaire, the Risky Sexual Behavior Questionnaire (RSBQ); and the Condom Barriers Scale (CBS). The statistical software R, analysis of variance post hoc and multivariate analysis of variance (MANOVA) logistic regression tests were used in data analysis
Results: The majority reported at least one lifetime experience of RSBs. Our results show that only 22% of the participants 'always' use condom in their sexual encounters. The lowest and highest subscale scores of the CBS were related to Sexual Experience (SE) (2.47 ± 0.86) and access/availability structure (3.52 ± 0.7), respectively. RSBs had negative significant association with Partner Barrier (PB) subscale scores (OR = 0.4; 95% CI: 0.22 to 0.73) and effect on SE subscale scores (OR= 0.54; 95% CI: 0.31 to 0.94).
Conclusion: RSBs was prevalent among our study population. RSBs and condom use barriers are significantly interwoven. The condom use barriers were highly associated with the types of sexual encounters such as group sex or casual sexual relations than specific mean of sexual performance (i.e. anal sex). Gender-specific RSBs, STIs/HIV/AIDS prevention program is recommended for women with SUDs.

Authors: Karimi Zahra , Ranjbar Reza , Najafi Ali
Published: August 2023

Background: Salmonella is one of the most leading causes of food-born infection and death among infants and people with the poor immunity system. Because Salmonella spp. have diversity in the genome composition and pathogenicity, access to rapid identification and genotyping is necessary to control of salmonellosis. The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) typing is a genotyping method that checks these variable sequences in the bacterial genome in a specific species. This study aimed to differentiate Salmonella strains using CRISPR region.
Methods: Salmonella isolates, previously identified via standard microbiological and molecular tests, were subjected to the study. Bacterial DNA was extracted and PCR was done using specific primers. The different PCR products were sequenced and the repeats patterns were used to identify additional or degenerate repeat clusters in the CRISPR region. All different sequences were analyzed using CRISPRtionary tool for dendrogram generation using the binary file.
Results: Overall, 119 strains of various Salmonella serovars were used. The result showed unique CRISPR and diversity in spacer both in sequence and the number. Analysis of the extracted sequence and band patterns illustrated that, except for S. infantis, both S. enteritidis and S. typhimurium isolates were classified as a separate cluster.
Conclusion: CRISPR genotyping could provide serotype/spacers dictionary and it is performed at low cost and high speed in comparison to the other typing methods. Therefore, the assessment of CRISPR and spacer content can be considered as a powerful and practical discriminatory method for subtyping of Salmonella isolates.

Authors: Mahusay Joren Raña , Sepelagio Elma Gubaton
Published: August 2023

The threat of antibiotic residues imposes a great concern in public health and at the same time in food safety. This study was conducted to screen antibiotic residues in retailed meats and evaluate the antibiotic sensitivity of indicator test organisms (Bacillus subtilis & Staphylococcus aureus). A total of 125 samples from three different types of meats (beef, chicken, and pork) were collected from the Public Market of Kabacan, Cotabato. Microbial Inhibition Assay utilizing B. subtilis and S. aureus were used for screening antibiotic residues. The total percentage of positive samples was 14.4%. The highest percentage was detected in chicken (22%) followed by beef (16%) and pork (6%), respectively. In evaluating the antibiotic sensitivity of test organisms, Bacillus subtilis detects Amoxicillin, Enrofloxacin, Tetracycline, and Oxytetracycline up to its maximum residual limits. There was no significant difference in beef (p > 0.05) and pork samples (p > 0.05) for the detection of antibiotics by the indicator organisms, while in chicken, the analysis revealed that the antibiotic sensitivity of test organisms was significantly different (p = 0.021). Hence, B. subtilis was ideal test organism than S. aureus (p<0.05). The binomial Logistic regression model also further suggests that B. subtilis was likely to be sensitive in detecting antibiotic residues in all meat types ( = -1.23, OR = 0.29, p = 0.013).

Methods & Materials: PubMed, Web of Science, Google Scholar, EMBASE, and the Ethiopian University online library were searched. The review took place between November 15, 2022, and December 15, 2022. Data were extracted using Microsoft Excel and analyzed using STATA statistical software version 14. The pooled prevalence of sexual and reproductive health service utilization was computed with 95% CI, whereas a log odds ratio was used to declare the statistical significance between associated factors and sexual and reproductive health service utilization.
Results: There were 1520 research articles retrieved, but 18 articles with 12,338 participants were met the inclusion criteria and included in this systematic review and meta-analysis. The pooled estimates of sexual and reproductive health service utilization among students was 42.606% (95% CI: 32.917%–52.295%; I2 = 88.3%). Discussion with families/friends  (OR=3.033, 95% CI=2.217-4.150, P-value<0.001, I2=75%) and knowledge  (OR=2.215, 95%CI=1.105-4.515, P-value=0.025, I2= 85%) were predictors of sexual and reproductive health service utilization among students.
Conclusion: In relation to the data from the studies under analysis, below half percent of students in Ethiopia utilized sexual and reproductive health services. Further health education and communication are crucial to improving knowledge about sexual and reproductive health services among students in Ethiopia.

Background & Aim: Healthcare workers are exposed to certain infectious diseases through needlestick injuries and exposure to blood and other bodily fluids. This study aimed to determine the prevalence of needlestick injuries and blood and other body fluids exposure among healthcare workers at Namazi Hospital in Shiraz, Iran.
Methods & Materials: This cross-sectional study was conducted on 656 Healthcare workers, including students and staff in medical, nursing, laboratory, service, and operating room groups, at the Namazi Hospital, in 2019. A questionnaire with four parts, including demographics, questions about using sharps containers, needle recapping, masks, and glasses, and the experience of sharps injuries or blood and body fluid exposure and reporting them, was distributed using the quota sampling method. To analyze the results, the T‑test and Chi-square test were performed.
Results: Nearly 75.2% of the participants always used sharps containers, and 21.7% never recapped syringes. Sharps injuries and blood and body fluid exposure occurred in 40.7% and 39.8% of the participants. Occupation (P<0.001), being a student (P: 0.048), and age (P: 0.008) were associated with sharp injuries. Occupation (P: 0.001), gender (P: 0.016), and age (P<0.001) differed in exposed and no exposed participants to blood and body fluids. The prevalence of reporting exposure was not significantly different between men and women, occupation groups, students and staff, and different ages (P> 0.05).
Conclusion: Hospital managers should provide effective educational interventions to protect against occupational hazard exposures. Also, they should provide protective equipment for Healthcare workers.

Published: August 2023

Background & Aim: Nursing staff are exposed to high-stress levels daily due to the demanding work environment. This study examined nursing staff occupational stress and coping mechanisms during the COVID-19 pandemic.‎
Methods & Materials: A cross-sectional study with a sample of 108 nursing staff was carried out. The Expanded Nursing Stress Scale (ENSS), the Brief Coping Orientation to Problems Experienced (Brief COPE) Scale, and constructed questions were used for data collection. Data were analyzed using chi-square (χ2), Pearson methods, and Multiple linear regression analysis. Statistical significance was determined at p-value ≤ 0.05.
Results:  Overall Occupational stress was assessed with a mean score of 146.8 (SD±35.3). In Brief COPE Scale, a higher mean was assessed for “social support - information seeking” and lower for “substance use” or “withdrawal” (p<0.001). A significant difference in response distributions was observed regarding their degree of concern or fear about COVID-19 (p<0.01). Increased levels of Overall Occupational Stress (ENSS) were associated with higher levels of BCOPE. Emotional Focus and Venting and Diffusion of Emotions (β=5.15, p=0.026), younger age of the participants (β=-5.78, p=0.033), years of working in the healthcare sector (β=14.46, p=0.004) or the highest fear/concern about being infected and infecting their patients (β=6.22, p=0.032).
Conclusion: Nursing staff experienced moderate levels of occupational stress, while challenges raised by the pandemic were handled through seeking social support, positive reframing and acceptance, taking protective measures, and turning to religion. Developing meaningful administrative and educational strategies for staff empowerment and resilience may reduce anxiety and occupational stress for nurses.

Background & Aim: Hungary started to administer several COVID-19 vaccines; however, attitudes toward COVID-19 and vaccination are still poorly understood. This study aimed to explore how the attitudes toward COVID-19 disease are associated with the attitudes toward COVID-19 vaccination in Hungary and compare the attitudes of health and non-health workers toward COVID-19 disease and vaccination in Hungary.
Methods & Materials: Using a descriptive, cross-sectional design, we recruited a sample of 1820 persons through an electronic survey. In addition to the sociodemographic questions, the attitudes towards COVID-19 disease and vaccination were assessed through self-developed, literature-based questionnaires. Principal component analysis, Spearman's correlation, linear regression, and the Mann-Whitney test were used in the data analysis.
Results: The mean age for the study participants (n=1735) was 43.8 ± 6.2 years, and females were the majority (84.6%). Overall, participants showed good attitudes toward COVID-19 disease (mean score= 3.48, SD= 0.43) as compared to their attitudes toward COVID-19 vaccination (Mean score= 2.67, SD=  0.44). A positive correlation was found between the attitudes toward COVID-19 disease and attitudes toward vaccination in Hungary (r= 0.247, p< 0.01). Nurses and other health workers showed more positive attitudes toward COVID-19 vaccination than non-health workers.
Conclusion: Hungarian decision-makers should intervene to improve the public's willingness to be vaccinated against COVID-19 or future pandemics. Health workers' knowledge and positive attitudes should be utilized in the media to encourage the general population to be vaccinated. The suggested questionnaires need to be validated for future pandemics' use.

Background & Aim: Establishing strategies to enhance evidence-based practice (EBP) requires a reliable instrument for assessing EBP competency. This study focused on translating and validating the Evidence-Based Practice Competency Questionnaire for Registered Nurses (EBP-COQ Prof©) in the Vietnamese context.
Methods & Materials: Through a methodological approach, this study performed cross-cultural adaptation and psychometric validation. The study involved 372 nurses selected through convenience sampling. Content validity was established using the Content Validity Index for Items (I-CVI) and the Content Validity Index for Scales (S-CVI). Construct validity was assessed via exploratory (EFA) and confirmatory factor analysis (CFA). Reliability was determined using Cronbach's alpha and the intra-class correlation coefficient (ICC). Criterion validity was examined by comparing EBP-COQ Prof© competency between nurses with and without prior EBP education.
Results: The Vietnamese version of EBP-COQ Prof© maintained consistency with the original version following cross-cultural adaptation. Content validity was confirmed with I-CVI> 0.78 and S-CVI/AVE= 0.97. EFA and CFA revealed consistent components with the original version: attitude (8 items), knowledge (11 items), skills (6 items), and utilization (10 items). Cronbach's alpha values were high: attitudes (0.965), knowledge (0.962), skills (0.909), and utilization (0.926). ICC values were also significant: attitudes (0.754), knowledge (0.895), skills (0.823), and utilization (0.966). Nurses with prior EBP education demonstrated higher EBP-COQ Prof© competency.
Conclusion: The translated and validated EBP-COQ Prof© provides a robust tool for assessing EBP competency among Vietnamese nurses. Its reliability, validity, and sensitivity to educational effects underscore its potential for promoting EBP in nursing.

Published: August 2023

The article presents research results performed using automotive spark ignition engine run on methyl and ethyl alcohols as well as gasoline as reference fuel. The research was performed on automotive engine of Fiat 1100 MPI type. The subject of the performed analysis was to compare operational parameters of the engine such as: engine power output, overall efficiency, emission of toxic components of exhaust gases, as well as comparison of course of combustion process calculated on the basis of recorded and averaged indicator diagrams, and on the basis of individual combustion cycles. The averaged diagrams were used in analysis of the pressure course during combustion, in analysis of pressure growth rate and heat release rate. Diagrams of individual combustion served for assessment of operational smoothness of the engine when fueled with alcohols. As the reference, parameters measured in case of gasoline fueling were used.
The experiments have confirmed stable engine operation on methyl and ethyl alcohols. Increase of engine power output with o 3.8-7.7% was confirmed for methanol and with 1.7-3.3% for ethanol, while increase of the efficiency with 1.5-7.5% was confirmed for methanol and with 1.2-2.5% for ethanol, comparing with gasoline fueling. Obtained results are pointing at possibilities of fueling of modern SI engines with alcohols only, especially including water-logged ethyl alcohol, obtained directly from distillery. This should increase share of alcohols in overall balance of consumed engine fuels.

The paper is focused on presenting a methodology for measuring power and torque based on diagnostic equipment available in most diagnostic workshops, such as OBD interfaces or the CAN Bus on-board data transmission network, under real-world road conditions. The publication presents an algorithm for calculating the powertrain’s torque and power based on measurements of changes in vehicle speed or acceleration recording during a two-phase road test. The results presented, based on the method described, apply to both the internal combustion and electric vehicle. Common powertrain operating parameters, such as maximum power, maximum torque and the powertrain’s flexibility parameters described in the literature are proposed for the final evaluation of the vehicle’s traction system.
Review of Interdisciplinary Approach to Swarm Intelligence
Authors: Kano Takeshi
Published: August 2023

Swarm intelligence is intelligence produced by multiple agents interacting with each other according to a simple set of rules, resulting in a system-wide intelligence. Such intelligence is found in a wide range of biological and social systems, and attempts have been made to understand the underlying principles through analytical approaches by biologists and sociologists and synthetic approaches by mathematical scientists and engineers. On the other hand, there are also attempts to construct artificial swarm intelligence systems that are not necessarily based on real-world phenomena. This review describes recent interdisciplinary research on swarm intelligence and its future prospects.
