Introduction. Since the registration of the first cases of COVID-19 in the PRC, due to the high migration activity of the population, the new coronavirus infection has spread throughout the world, including the Russian Federation.Aim. To establish the features of the spread of a new coronavirus infection in the Rostov Region. Materials and methods.The analysis of 81 cases of the importation of a new coronavirus infection by persons who arrived in the Rostov Region from abroad or other regions of the Russian Federation was carried out based on the data of the Rostov Region office of the Federal Service for Supervision of Consumer Protection and Human Welfare. The dynamics of the spread of COVID-19 in the administrative territories of the Rostov Region has been analyzed. The data of viral genome-wide sequencing (n = 155) carried out in the Rostov-on-Don Research Anti-Plague Institute were used in this study.Results. In the period from 03/21/2020 to 03/28/2020, cases imported both from abroad and from other regions of the Russian Federation were registered in the Rostov Region, , mainly on the territory of the Rostov urban agglomeration. The vector of the spread of the disease was directed from the administrative center of the region to the periphery. The emergence of a new genetic line B.617.2 (Delta) probably led to a significant increase in the incidence in the Rostov Region.Conclusions. The spread of a new coronavirus infection in the Rostov Region was facilitated by the one of the main social factors of epidemiological risk, the population migration, which led to the importation of the infection to the administrative center of the subject, Rostov-on-Don city. Taking into account peculiarities of the Rostov region, the largest proportion of COVID-19 cases was recorded in the Rostov urban agglomeration. Against the background of the dominance of the “Delta” variant of the virus on the territory of the Rostov region, there was a tendency towards an increase in the number of cases.

Introduction. Klebsiella pneumoniae in human microbiota may appear as a part of commensal microbiota, and as hypervirulent pathogen, for example, hypermucoid pathotype. This pathotype is characterized by certain genetic determinants, leading to the possibility of detecting the pathogenic potential of isolates by PCR. Aim of the study: to evaluate and compare pathogenic potential of K. pneumoniae isolates from practically healthy people, patients with inflammatory bowel disease (IBD) and extraintestinal infections (ExII).Materials and methods. Testing was performed with the set of nucleotides for multiplex PCR analysis targeting eight potentially virulent genes with the following functions: ferrum uptake (ybsT, kfu, iutA), adhesion and invasion (mrkD), hypermucoid phenotype and virulent serotypes (mrkD, magA, rmpA, k2) and metabolism of allantoin (allS). PCR assay was used to screen Klebsiella pneumoniae isolates from feces of patients with IBD (69 isolates) and of practically healthy people (68 isolates), and multiresistant isolates from biological material (blood, urine, surgical wounds, bronchoalveolar lavage) of patients with extraintestinal infections (mrExII, 25 isolates).Results. Results of the testing demonstrated association of four of targeted determinants with the patients diagnoses. YbtS gene was significantly more often found in isolates from IBD (р = 0.024) and mrExII (p 0.001) groups. RmpA gene was significantly more often detected in IBD group (р = 0.038). Extraintestinal infectious isolates were significantly (р ≤ 0.001) enriched with mrkD and allS genes (р = 0.032).Conclusion. The most potentially virulent group was isolated from patients with extraintestinal infections, the least virulent — isolates from feces of practically healthy people. The most frequently detected virulence genes were involved in adhesion and hypermucoid phenotype formation.

Introduction. Currently, there is an increasing importance of microbial associations in the pathogenesis of genital inflammatory diseases. However, the issues of deciphering the taxonomic affiliation and the diagnostic significance of the bacteria detected in this case remain unresolved.The aim of the study was to review the diagnostic significance of the quantitative approach in determining the etiological role of microorganisms in andrology.Materials and methods. For the study, samples of ejaculate and/or discharge from the urethra from 15 men who were in infertile marriages, 12 with a confirmed diagnosis of "acute genital gonococcal infection" were used. The testing included a classic bacteriological study and the metagenomic analysis of 16S ribosomal RNA samples carried out at the Department of Collection Cultures of the State Research Center for Applied Microbiology (Obolensk). To standardize the distribution of samples into groups based on the indicators of alpha diversity and the concentration of putrescine, the range of variation and the average linear deviation were used. Statistical analysis of the obtained data was carried out using Excel software (MS Office package).Results. The microbial landscape of the ejaculate was characterized by the predominance of representatives of the genera Enterococcus, Neisseria, Lactobacillus, Corynebacterium, Prevotella, Bacteroides. Stable associations of E. faecalis and M. osloensis were detected in the ejaculate. When using the cultural method, representatives of the genus Moraxella were not isolated in any sample. It was shown that discrepancies can affect not only quantitative indicators, but also reveal inconsistencies between the qualitative assessment of detected genetic markers and the results of identification in a bacteriological study of individual representatives of similar or phenotypically similar taxa.Discussion. The results of this study indicate that the lesser diversity of opportunistic pathogens gives them more opportunities to realize their pathogenic potential. On the other hand, in a complex community with greater alpha diversity, its realization is hindered by a complex intermicrobial relationships and the need to survive.Conclusion. As a result, it seems that the most promising approach is the integrated use of cultural methods and metagenomics with a comparative statistical analysis of the obtained qualitative and quantitative indicators.

Introduction. Listeria monocytogenes is an important human pathogen causing various forms of listeriosis, including foodborne infections, meningitis, neonatal sepsis, and abortion. Listeria are common all over the world.The purpose of the study was to conduct microbiological monitoring of L. monocytogenes in water reservoirs near livestock premises in the Vologda district of the Vologda region.Materials and methods. Bacterial cultures were isolated using two methods, titration and filtration, followed by analysis using methods of conventional bacteriology, serotyping, and species identification by instrumental procedures such as whole genome sequencing, and bioinformatic analysis.Results. Three isolates of L. monocytogenes and one isolate of Listeria innocua were isolated from 12 analyzed water samples (wastewater — 6, river water — 4, and storm water — 2 samples). whole genome sequencing of three L. monocytogenes strains attributed them to the evolutionary line II, and to three sequence types and two serogroups ST425(1/2a-3a), ST20(1/2a-3a), ST7 (4a-4c). The strains are shown to belong to multiple drug resistant ones conferring resistance to three functional groups of antibacterials such as tetracyclines, macrolides, and sulfonamides. Antibiotic resistance genes (fox, psp-like, lin,norB,sul), virulence Islands LIPI-1 and LIPI-2, and virulence genes inlABCJ, oatA, ami, gtcA, vip, and lisK in genomes of the strain were identified. Stress tolerance Island SSI-1 was identified in one strain.Conclusions. The data obtained indicate contamination of water sources near the livestock premises with L. monocytogenes strains possessing high pathogenic potentiality for outbreaks of listeriosis in humans. This shows the necessity of careful monitoring of water sources for the presence of the causative agent of listeriosis as well as the implementing of anti-epidemic measures.

The aim: In vitro identification of targets for antagonism factors in klebsiellas and enterococci for Candida albicans isolated from the intestinal microbiome of HIV infected patients.Materials and methods. The tests were performed using 38 Candida albicans strains, 28 Klebsiella pneumoniae strains, and 30 Enterococcus faecalis strains isolated from the intestinal microbiome of 89 HIV infected children. The mean age of the patients was 24 ± 2 months; the group consisted of 49 (55%) boys and 40 (45%) girls. Microorganisms were isolated from the intestinal biotope using such selective media as HiChrome Candida Agar, HiChrome Klebsiella Selective Agar Base, and Enterococcus Agar; the study included identification of species. Model experiments were performed to study anti-catalase activity of E. faecalis exometabolites and the impact of K. pneumoniae on morphological transformation of C. albicans fungi.Results. Klebsiellas decrease the intensity of germ tube formation in C. albicans by 58.7% (p 0.01). When cocultured, 12.3% of the yeast cells produce germ tubes, while 29.8% of transformed cells was detected in the fungal monoculture. It has been found that exometabolites of 65.7% of E. faecalis strains decrease production of catalase in C. albicans. The initial catalase level in untreated cultures of C. albicans averages 1.02 µmol/min of optical density; after they are treated with E. faecalis exometabolites, the level decreases to 0.55 µmol/min, i.e. by 46.1% (p 0.05).Conclusions. K. pneumoniae and E. faecalis demonstrate antagonism of different intensity toward C. albicans. Morphological transformation and catalase production are targets for antagonism factors of facultative microbiota in C. albicans.

Introduction. The emergence of new epidemiologically significant variants of SARS-CoV-2 has shifted emphasis to development of a live vaccine, which would be able to provide protection against a wide range of antigenic variants of the virus. The aim of the study was to obtain SARS-CoV-2 variants attenuated through cold adaptation and to provide their biological characterization.Materials and methods. The Dubrovka laboratory strain of SARS-CoV-2 and its variants were cultured on Vero and Calu-3 cells. The virus quantification was performed by virus titration in Vero cells and by real-time reverse transcription-polymerase chain reaction. SARS-CoV-2 virions were analyzed using transmission electron microscopy. Genome sequences of the virus were identified by nanopore sequencing. The attenuation (att) phenotype of SARS-CoV-2 variants was identified using Syrian hamsters as an animal model for COVID-19. Results. Cold-adapted (ca) SARS-CoV-2 variants – Dubrovka-ca-B4 and Dubrovka-ca-D2 were produced by continued passaging of the Dubrovka strain in the Vero cell culture at the temperature being gradually decreased to 23ºC and by subsequent cloning. Up to 20 nucleotide substitutions and 18 amino acid substitutions were detected in genomes of ca-variants. Ca-variants, as distinct from the parent Dubrovka strain, actively replicated at 23ºC, while the Dubrovka-ca-D2 variant had a temperature-sensitive (ts) phenotype (did not replicate at 39ºC). Ca-variants of the virus replicated poorly at 37ºC in the Calu-3 human lung cell culture, which, along with the ts-phenotype, can be a marker of virus attenuation for humans. In the intranasally infected Syrian hamsters, ca-variants of the virus demonstrated an attenuation phenotype: they did not cause loss of appetite, fatigue, drowsiness, did not slow down weight gain, replicating much more slowly in the lungs and brain compared to the virulent Dubrovka strain. Conclusion. The obtained attenuated SARS-CoV-2 ca-variants, Dubrovka-ca-B4 and Dubrovka-ca-D2, should be studied further as candidate vaccine strains for a live attenuated vaccine against COVID-19.

Published: September 2022

In a situation where metaverse is regarded as a new benchmark of platform economies and vast investment on metaverse is needed in and out of country, this paper proposes the direction of public support for metaverse-related technologies based on the support direction of national R&D budget projects and the understanding of metaverse technology and market environments.
We investigate the current situation of R&D supports in the national level and admit the necessity of increasing CT(culture technology) investment. Furthermore, we find the R&D support principle that the direction of public supports in R&D investment be more desirable in indirect and ex post tax supports than in direct and ex ante fiscal supports, even in metaverse technology and market cases.
It is needed, firstly to increase tax supports for metaverse-related technologies by adding those to immersive contents or culture contents technologies in new-growth engine and proprietary technologies, and secondly to focus on global standardization for mega investment in the infrastructure area of metaverse value chains, and thirdly to promote small investment on creative and immersive innovations in the service area of metaverse value chains through deregulation and public private partnership. Therefore, in the short-run viewpoint and for the long-run performance of metaverse tech and market environments, the evaluation framework and tax expenditure evaluation is timely for the addition of metaverse-related technologies into new-growth engine and proprietary technologies in tax supports.

Published: September 2022

Culture & Arts centers have been dramatically increasing due to the governmental policies and increasing demands of using them for the recent years. However, there have been some problems from the central and local governments’ manipulations for achievements or patronization that they can’t play a role not fit to their original purposes. As reflecting the fact, the operating status by culture & arts centers are different, and it is expected that such institutes shall be built strictly based on the social economy in future. This study aims at presenting the analysis of social economy using real option method could be usefully utilized with considerations on irreversibility and uncertainty of investment on culture & arts centers, and convenience of investment. Therefore, the binomial option model of real option methods was applied for simulation on the culture & art center in Daejeon. As a result of the analysis, in the case of the culture & arts center, when considering its ‘operational expansion option’ at specific time, its economy would be highest with accomplishment of the economies of scale.
Maurice Hauriou’s Theory of the Institution: Legal Institutionalism and the Science of the State
Authors: Węgliński Cezary
Published: September 2022

The aim of this paper aims is to reconstruct the original context,  the characteristics and the main assumptions of M. Hauriou’s theory of the institution as one of the most coherent and comprehensive examples of legal institutionalism. By means of critical source analysis, the paper presents the basic elements of the notion of the institution together with its ontological and epistemological assumptions concerning both the very concept of law and legal methodology. The second part of the paper presents the critical approach expressed in Hauriou’s theory towards some core concepts of public and constitutional law by opposition to traditional, normativist and positivist approaches to constitutionalism. Hauriou’s work, despite its importance as indirect inspiration for contemporary doctrines of constitutional pluralism, is nowadays barely present in European legal science discourse. The last part of the paper is therefore dedicated to some closing remarks on current relevance of the theory of the institution with particular focus on the challenges of increasing pluralism of legal orders.

Published: September 2022

ZnO semiconductors are good photocatalysts for degrading volatile organic pollutants into CO2 and H2O. Activated carbon has a high absorption capacity, and contains amorphous carbon. The purpose of this study was to determine the effect of variations in the concentration of ZnO on activated carbon on the band gap after impregnation. Determination of Bandgap value was determined using UV-DRS with the Tauc Plot method. The effect of variations in ZnO concentration on activated carbon on the band gap after impregnation shows the band gap value. The change in band gap value is caused by electron resonance when electrons from ZnO interact with polycyclic aromatic activated carbon. At the 20% variation there is a widening of the band gap value caused by a short wavelength shift. The conclusion obtained is that the characteristics of the AC-ZnO catalyst have band gap values ​​for each variation, namely 2.69 eV, 2.7 eV, 2.97 eV, 4.85 eV and 3.0 eV. The band gap values ​​increased with increasing concentrations of ZnO 5%, 10% and 15%.

O presente trabalho teve como objetivo avaliar o efeito dos brassinosteróides no crescimento de mudas de pinhão sob déficit hídrico. O experimento foi realizado na Universidade Estadual de Goiás, Unidade de Ipameri- Goiás, em casa de vegetação com 100% de interceptação da radiação solar. As mudas de Jatropha curcas, foram plantadas em vasos de cinco litros, contendo uma mistura de solo, areia e esterco na proporção de 3:1:0,5, respectivamente. O experimento foi conduzido em um delineamento inteiramente casualizado, no esquema fatorial 3x5 [hormônio (0,0, 0,25 e 0,50mg L-1) x restrição hídrica (níveis de suprimento hídrico: 20%, 40%, 60%, 80% e 100% da evapotranspiração diária)] em três repetições. Após 15 dias de imposição dos tratamentos foram avaliadas características morfofisiológicas, transpiração, teor relativo de água, pigmentos fotossintéticos e extravasamento de eletrólitos. Os dados foram submetidos à análise de variância, com médias comparadas empregando-se o teste de Newman-Keuls ao nível 5% de probabilidade. A aplicação de brassinosteróides via foliar não amenizou os efeitos do déficit hídrico nas plantas, interferindo decisivamente no crescimento do pinhão manso. Houve menor área foliar com a pulverização com solução de 0,25mg L-1 associado a menor evapotranspiração.

The intercropping of maize with forage plants is a farming technique aimed at producing grains and grazing, with beneficial results for the sustainability of production. Most of the research carried out with maize (Zea mays) intercropped with palisadegrass (Urochloa brizantha) has evaluated the agronomic performance of the crops. Therefore, there is a lack of research on the effects of this technique on the soil hydro-physical characteristics. For this reason, the objective of this study was to evaluate the effects of the cultivation of maize intercropped with U. brizantha on the soil hydro-physical characteristics. The study was conducted in an experimental area at Faculdade Católica of Tocantins, in Palmas/Tocantins, Brazil; using a randomized complete block design, in a 4x2 factorial scheme, with three repetitions. The study comprised four types of intercropping: i) maize with U. brizantha cv. Marandu sown by broadcast; ii) maize with U. brizantha cv. Marandu sown between the maize rows; (iii) maize with U. brizantha cv. Piatã sown by broadcast; iv) maize with U. brizantha cv. Piatã sown between the maize rows; and two implantation periods: v) simultaneous sowing; vi) sowing 20 days after the maize. The hydro-physical properties evaluated were soil density, total soil porosity and soil water holding capacity. There was a significant interaction between the type of intercrop and the sowing time in the soil density and total soil porosity, but no significant differences in soil water holding capacity. Results show that the intercropping of maize with U. brizantha sown simultaneously improves the physical properties of the soil such as density and porosity, in comparison to the U. brizantha implantation 20 days after sowing maize. The intercrop of i) maize with U. brizantha cv. Marandu sown between the maize row and ii) maize with U. brizantha cv. Piatã sown by broadcast between the maize row (in simultaneous sowing) improvedthe soil physical attributes.

Published: September 2022

In the feed industry raw material, grinding is an integral part of the production cycle. However, this process is characterized by significant energy consumption – from 3 to 100 kW * hour per ton of finished goods, and only a part of it is directly spent on grinding. Therefore, this scientific research is aimed at minimizing the consumption of energy resources by technological machines – crushers and improving the energy efficiency of the process in general is an urgent issue.
A powerful modern research method of studying complex objects is system analysis, which enables to modernize existing machines and design new ones without conducting a large number of expensive physical experiments. Unfortunately, this method is not yet widely used in the research and design of new machines for processing agricultural products, since there are no developed and substantiated engineering theories describing the behaviour of the processed material in the workspace of the technological machine.
Grinding grain with a moisture content indicator at the level higher than the base condition, there is a low efficiency of the method of impact grinding, that is determined by the increased plasticity of the material and an increase in the value of the marginal deformation, which can lead the grain towards destruction. A partial solution of this problem is possible when combining the method of cutting and hammering, which has formed the basis of a technical solution implemented in the scientific laboratory of Vinnytsia National Agrarian University, where the design has been developed and experimental verification of the vibrating crusher have been carried out. Further improvement of the energy efficiency of the technological operation of grain grinding requires theoretical researches of the dynamics of the process, and determining the minimum amount of energy required for destruction.
The article deals with the laws of solid mechanics and the use of rheological methods in researching disperse systems, it presents the values of absolute deformation and the work that is carried out during the destruction of maize grain under the influence of applied impact-cutting load in analytical and graphic form. Moreover, the results of this research help us to establish the marginal values of plastic and elastic absolute deformations occurring in the material, which is a prerequisite for the theoretical substantiation of the grinding law.

Authors: Matviychuk Viktor , Mikhalevich Volodymyr , Kolisnyk Mykola
Published: September 2022

The article presents the results of development and research of technological schemes of planting flanges on tubular (ring) workpieces by stamping by rolling cylindrical and conical rolls. It is shown that the achievement of significant dimensions of the various elements of the workpiece is possible by providing a directed flow of metal by changing the relative position of the roll and the workpiece. Planting of external flanges is one of the most effective operations of stamping by rolling, as it allows you to form a wide range of products with advanced geometric elements. To assess the technological capabilities of the flange landing operation, the most dangerous from the destruction positions of the workpiece zone was identified and the analysis of the stress-strain state of the material using the method of grids, hardness measurement and microstructural analysis. According to the results of the research, the ways of deformation of the particles of the material of the peripheral surface of the flange in the coordinates "intensity of deformations - an indicator of the stress state" are schematically constructed. These deformation paths are given against the background of curves of ultimate deformations of steels, which are built on the results of uniaxial compression and torsion of cylindrical specimens and using tested approximations. A mathematical model of deformation trajectories is constructed, for which a one-parameter function is taken as a basis, which is "glued" from the elementary function of the sine and tangent to it at some point in the line. To determine the used plasticity resource, a damage summation model with a power approximation of the damage function was adopted. As a result, we have for the first time described the general expression of the linear damage summation model for the case of the parametric deformation path problem. The graphical representation on the constructed model of accumulation of damages in material of a dangerous zone of a flange at landing by a method of SHO is resulted. Based on the constructed model, it is possible to model the accumulation of damage by changing the values of the model parameters for different materials and deformation paths, which, in turn, depend on the relative geometric parameters of the workpiece and its location relative to the rolling roll.

Introduction. Serological tests have been a valuable tool during the SARS-CoV-2 pandemic, supporting molecular methods for detection, and monitoring the immune response, caused by vaccination or by natural infection. Within all these techniques, rapid tests are interesting due to their ease of use, rapid response and low cost. Methods. Two different immunological techniques were evaluated: Realy Tech and Mikrogen Diagnostik recomLine SARS-CoV-2 IgG. SARS-CoV-2 IgG II Quant antibody test and SARS-CoV-IgG assay, both from Abbott Diagnostics, were used as reference techniques. Results. Mikrogen Diagnostik recomLine SARS-CoV-2 IgG shows the best results (S=0.985; E=0.839). Three techniques offered good positive predictive values, but Realy Tech and Healgen negative predictive values left to be desired. Conclusions. Mikrogen Diagnostik recomLine SARS-CoV-2 IgG showed good results in the detection of antibodies against SARS-CoV-2 and could be used as an alternative to automated techniques.

Published: September 2022

While some research has been conducted in sub–Saharan Africa on the alien invasive Parthenium hysterophorus, little work has assessed whether it is poses negative impact on native forages. A field survey was carried out to study the dominant co–existing plant species, and its impact on plant abundance, species, and native forage cover. We found that non–natives were the dominant co–existing plants with P. hysterophorus compared to natives. Plant species (r = -0.889, P = 0.043) and abundance (r = -0.968, P = 0.007) decreased with increasing invasive percent cover. Moreover, native forage plant (Brachiaria reptans; r = -0.922, P = 0.026), Cynodon dactylon; r = -0.972, P = 0.006, Digitaria milanjiana; r = -0.938, P = 0.018, and Indigofera spicata; r = -0.977, P = 0.004) percent cover decreased with increasing invasive percent cover. The study concludes that P. hysterophorus negatively affects plant diversity, and thus, should controlled.

Published: September 2022

In the year of the centennial of Sophia de Mello Breyner, we accessed to numerous initiatives that have the intent of honoring the author. Among them, we name the edition of “A Menina do Mar”, “A Floresta”, “A Fada Oriana” and “O Menino de Bronze”, that have always inspired the imagination of children. We also find numerous proposals that shows the inspiration of the composers and artists on the author’s texts, namely “A Menina do Mar”. The metamorphosis into a musical short story in Ayres de Abreu’s 2019 version was for us the starting point for a broader search for other versions of the work. It should be noted that not only Ayres de Abreu is interested in the work, but Sassetti and Raposo, as well as Lopes-Graça, understand the treasure of its speech and imaginary sound, musical, plastic and visual richness.In this context, we intend to reflect on the way how Lopes-Graça approaches the text, but also Sassetti and Raposo, as well as Ayres de Abreu. We want to know how they inform it, through conceiving different performance registers of the work. From its analysis, we intend to assess the solutions, as well as the evolution proposed in them. How are the successive episodes of the narrative treated? How are the speeches in the text informed? Faced with an intense and peculiar language like Sophia’s, we expect to find out to what extent A Menina do Mar (re)says and (re)interprets itself in the proposed performative versions.
Florida extension agents’ perceived level of trust with their county extension director
Authors: Benge Matt , Cash Elisha
Published: September 2022

County Extension Directors (CEDs) act as the administrative leader of the county Extension office and implement their own educational program. County Extension agents act as the leader of their program area and corresponding community audience. Because of the autonomous nature of the agents’ work, it is imperative that Extension agents trust their CEDs. The Trust in Leaders Scale (TLS) was created to measure person-based trust between leaders and followers through four constructs: competence, integrity, benevolence, and predictability. A census study was conducted by distributing the TLS to the UF/IFAS Extension agents that report to a CED. Results indicated perceived moderate levels of trust between agents and CEDs, and demographic variables did not impact whether agents trusted their CED. UF/IFAS Extension should seek to understand the impact of moderate trust between county Extension agents and their CED, as research show low trust typically leads to lower job satisfaction and higher employee turnover.

En la sociedad actual, los conocimientos se generan y emiten utilizando múltiples canales y códigos que el alumnado universitario no siempre domina. La investigación realizada pretendía conocer las carencias que presenta este alumnado en el desempeño de la competencia comunicativa. En este artículo presentamos la situación de partida en la que se encuentran los futuros docentes de dos universidades españolas, Jaén (149 alumnos) y Oviedo (125 alumnos), con respecto a la competencia comunicativa. Para ello, se elaboró un cuestionario, cuyos resultados muestran diferencias significativas entre el alumnado de ambas universidades sobre todo en la dimensión socio-lingüística.
A robust Bayesian test for identifying context effects in multiattribute decision-making
Authors: Katsimpokis Dimitris , Fontanesi Laura , Rieskamp Jörg
Published: September 2022

Research on multiattribute decision-making has repeatedly shown that people’s preferences for options depend on the set of other options they are presented with, that is, the choice context. As a result, recent years have seen the development of a number of psychological theories explaining context effects. However, much less attention has been given to the statistical analyses of context effects. Traditionally, context effects are measured as a change in preference for a target option across two different choice sets (the so-called relative choice share of the target, or RST). We first show that the frequently used definition of the RST measure has some weaknesses and should be replaced by a more appropriate definition that we provide. We then show through a large-scale simulation that the RST measure as previously defined can lead to biased inferences. As an alternative, we suggest a Bayesian approach to estimating an accurate RST measure that is robust to various circumstances. We applied the two approaches to the data of five published studies (total participants, N = 738), some of which used the biased approach. Additionally, we introduce the absolute choice share of the target (or AST) as the appropriate measure for the attraction effect. Our approach is an example of evaluating and proposing proper statistical tests for axiomatic principles of decision-making. After applying the AST and the robust RST to published studies, we found qualitatively different results in at least one-fourth of the cases. These results highlight the importance of utilizing robust statistical tests as a foundation for the development of new psychological theories.
Object memory is multisensory: Task-irrelevant sounds improve recollection
Authors: Duarte Shea E. , Ghetti Simona , Geng Joy J.
Published: September 2022

Hearing a task-irrelevant sound during object encoding can improve visual recognition memory when the sound is object-congruent (e.g., a dog and a bark). However, previous studies have only used binary old/new memory tests, which do not distinguish between recognition based on the recollection of details about the studied event or stimulus familiarity. In the present research, we hypothesized that hearing a task-irrelevant but semantically congruent natural sound at encoding would facilitate the formation of richer memory representations, resulting in increased recollection of details of the encoded event. Experiment 1 replicates previous studies showing that participants were more confident about their memory for items that were initially encoded with a congruent sound compared to an incongruent sound. Experiment 2 suggests that congruent object-sound pairings specifically facilitate recollection and not familiarity-based recognition memory, and Experiment 3 demonstrates that this effect was coupled with more accurate memory for audiovisual congruency of the item and sound from encoding rather than another aspect of the episode. These results suggest that even when congruent sounds are task-irrelevant, they promote formation of multisensory memories and subsequent recollection-based retention. Given the ubiquity of encounters with multisensory objects in our everyday lives, considering their impact on episodic memory is integral to building models of memory that apply to naturalistic settings.

This study aims to review the use of data analytics and artificial intelligence in fraud detection to support internal audits. This study employs a qualitative method with a scoping review approach. The research data comprised 24 online journal articles indexed by Scopus and Sinta, which were used as the basis for scoping reviews. The stages carried out in this study consisted of identifying research questions, using keywords, selecting literature, mapping the results of research data, and compiling a summary of research results. This study concludes that the fraud detection model based on data analytics and artificial intelligence has a high accuracy value in improving audit quality. This study indicates that the Indonesian Financial and Development Supervisory Agency needs to increase the use of technology, including data analytics and artificial intelligence, to detect fraud optimally.
The Effect of Team Efficacy and Perceived Loafing on Team Satisfaction and Individual Academic Achievement in Team-Based Learning of General Education
Authors:   Korean Association for Literacy, Yu Kyong Ae
Published: September 2022

This study analyzed the correlation and interaction effect of each variable from 106 students to examine how team efficacy and perceived loafing affect team satisfaction and individual academic achievement in team-based learning of general education. The results showed that team efficacy had a significant effect on learning outcomes, but perceived loafing was not significant to learning outcomes. Gender analysis revealed that male students had higher team efficacy and rated higher in team satisfaction and academic achievement than females. This suggests that higher team efficacy leads to higher team satisfaction and academic achievement. In an analysis by majors, science engineering students who showed higher team efficacy and lower perceived loafing rated higher in task performance and ability both by their team members and themselves. This suggests that when team efficacy is higher and perceived loafing is lower, learners are more dedicated to team assignments. In this study, however, the interaction effect of team efficacy and perceived loafing on learning outcomes was not significant unlike in the two previous studies (Yu Ji-won, 2014; Jwa Hyun Suk, 2020). It might be because of other factors, such as differences in intimacy among team members and learner perceptions between major education and general education. In future studies, the relationship between variables should be identified from a more multifaceted perspective, with the hope that the results of the study can be utilized in teaching and learning strategies in the field of education.
Case Study of Process-Oriented Writing Course Development: Focusing on the  Course at UNIST
Authors:   Korean Association for Literacy, Jeong Yun Na
Published: September 2022

This study presents a writing education model based on a process-oriented approach that can be integrated in college writing courses and to confirm the significance of education. This paper introduces the process of developing the course structure and curriculum on , a liberal arts subject at Ulsan National Institute of Science and Technology. Next, learner response and the significance of education were examined, focusing on the postscript and review sections of the task activity written by learners in the expressive writing phase, i.e., the first half of class.
In the  course, which consists of two phases: expressive writing and academic writing. Learners write two articles during one semester, learning theory and practice simultaneously. In the expressive writing stage of the first half of this class, which is the focus of this paper, learners learn and practice the process and method of writing and the basic principles of writing experientially. At this time, they practice applying their writing knowledge - which has stayed only at the level of knowledge - to actual writing performance, and they are trained to observe and check their writing process and adjust their writing activities by writing a review of the activities prescribed in all practice courses.
The significance of writing instruction presented in this paper is that it enables learners to apply their writing knowledge to actual writing performance, to understand empirically the process and method of writing that they knew only superficially, and to convey the importance of all the stages of writing and to understand the sequence of these steps recursively. Moreover, it helped learners to develop the power to control and direct their writing activities by understanding their own writing process. In this way, it was possible to confirm the importance of providing an actual writing experience in the writing classroom and the usefulness of continuously observing and communicating about learners' writing processes.
The Practice and Effect of Dictogloss for Teaching Migrant Workers’Korean Writing
Authors:   Korean Association for Literacy, Nam Hyeon-jeong , Kim Jinung
Published: September 2022

This study aims to apply the Dictogloss teaching method, which can efficiently promote various language areas for migrant workers who have difficulty securing sufficient learning time, to actual classes and confirm its effectiveness. Specifically, a research class was conducted on 16 migrant workers to find out whether Dictogloss affects the improvement of Korean language skills of migrant workers.
First, in order to find out the change in writing skills of the study participants, a pre/post writing evaluation was conducted to confirm that the average score was 17 points or more different in post-writing compared to pre-writing. Second, surveys and post-interviews were conducted to find out the study participants’ perception of Dictogloss. Through the survey, it was confirmed that participants had a positive perception of Dictogloss and had high preference. Through the post-interview, it was confirmed that Dictogloss’ cooperative learning increased the participation of migrant workers in classes, which led to the improvement of Korean language skills. In addition, it was confirmed that vocabulary skills were improved as well as listening and speaking skills, including writing. However, the limitations of Dictogloss could be confirmed due to the lack of Korean language skills and difficulty in discussion due to differences in academic background.
