The article presents the results of the questionnaire interview designed for the purposes of this particular study. The authors chose to reveal the multi-facetedness of the theme in question, i.e. focus on the possibilities and the future that computer-based etertainment offers, leading to transformations both externally and internally.
How the analytical hierarchical process and revitalisation work together: A case study of Poland
Authors: Rogatka Krzysztof , Starczewski Tomasz , Kowalski Mateusz
Published: January 2023

Due to the multifaceted nature of the revitalisation process, its evaluation and monitoring, as well as possible comparisons, are complex and difficult to carry out. Evaluation of the revitalisation process currently poses a challenge for all municipalities. The article aims to compare the revitalisation process in the two Polish cities of Toruń and Bydgoszcz. The analysis was based on two financial perspectives: 2007–2015 and 2016–2023. The authors chose a multi-criteria analysis method based on the analytical hierarchical process (AHP) as the main research method. The results show that the Local Revitalisation Programme of the City of Toruń for the years 2007–2015 had the best impact on the revitalisation process. Using the AHP method, we could carry out a multidimensional evaluation of the revitalisation process. Moreover, it allowed us to combine different elements of the evaluation of the revitalisation process and transform them into one synthetic result, ranking each programme in a hierarchy. At the methodological level, the article presents a new approach to conduct research in socio-economic geography, using the tool of multi-criteria analysis derived from the disciplines of economics and management sciences. Until now, the AHP method has not been used in the analysis of the revitalisation process, which confirms the innovative character of the conducted research.

Published: January 2023

In this study, the influence of crumb rubber added by dry process on the dissipative properties of bituminous mixtures has been investigated. Six mixtures were tested: two reference mixtures without crumb rubber were produced, one containing a pure binder and the other one containing an SBS-modified binder. Four other mixtures containing 2 % and 4 % (in mass) of crumb rubber and the same two mentioned binders were also produced. First, complex modulus tests were carried out at different frequencies and temperatures and for an axial strain amplitude of 50 μm/m. The 2S2P1D analogical linear viscoelastic model was used to model experimental data. From these results, the dissipated energy during one sinusoidal loading cycle was calculated, both for constant strain amplitude loading and for constant stress amplitude loading. Simulations at constant strain amplitude show lower energy dissipation for bituminous mixtures containing 2 % and 4 % CR and the SBS-modified bitumen with respect to the corresponding reference mixture without CR. However, the opposite is found at constant stress amplitude. Mixtures containing pure bitumen and CR show lower dissipated energy for any loading mode. Numerical simulations were carried out to determine energy dissipation at the scale of a pavement structure. The linear viscoelastic properties determined experimentally for the different materials were implemented in a finite element model to perform the calculations in the frequency domain. Results show that pavements made with bituminous mixtures containing CR added by dry process dissipate more energy with respect to the reference mixtures without CR.
Thermal Performance of Wall Systems Utilizing Radiant Barriers
Authors: Huygen Nathaniel , Sanders John
Published: January 2023

Typical brick veneer wall assemblies contain an air space to provide drainage inside the wall. This air cavity results in heat transfer through the wall via conduction, convection, and radiation, with radiation typically being the dominant heat transfer mechanism across the air space. Due to the significance of radiative heat transfer, any modification to the surface properties of the wall facing the air space can result in significant energy savings if the radiation heat transfer can be reduced. Radiation heat transfer can be minimized by installing a radiant barrier in the brick veneer wall. A radiant barrier is a thin metallic foil whose surface has an average emissivity of around 0.05. In this research study, first several commercially available radiant barriers were characterized using a heat flow meter apparatus. The thermal emissivity was estimated indirectly by measuring the thermal resistance of a known air space. Second, small-scale hot box testing was carried out to determine if the radiant barriers performed as expected in a more complex wall assembly. Third, full-scale hot box testing was carried out using one of the commercial radiant barriers. Finally, finite element models were verified against experimental results to allow for predicting the performance of radiant barriers in other wall systems. It was found that installing a radiant barrier in a typical residential brick veneer wall resulted in an increase in the R-value of the system and a significant increase in the dynamic thermal performance of the wall.
Impact of Wall Ties on the Steady-State Thermal Performance of Wall Systems
Authors: Huygen Nathaniel , Sanders John
Published: January 2023

Wall ties or masonry veneer anchors are a common part of brick veneer wall assembly construction. They serve to anchor the brick veneer to the backup wall, whether that is a wood-stud, steel-stud, or concrete block wall. They provide structural support and keep the brick veneer from moving. However, since wall ties are made from steel, they have a significantly higher thermal conductivity than the surrounding materials in the building envelope, and this difference may cause thermal bridging. The overall impacts of several common types of wall ties in residential and commercial construction were tested using a small-scale hot box apparatus under steady-state conditions. Each test panel was first tested without any wall ties and then subsequently tested with wall ties present. This procedure allowed for direct measurement of the impact of the wall tie while holding all other factors constant. In the case of a typical residential wall without continuous insulation, both types of wall ties tested were found to have no measurable impact on the overall thermal performance. In the commercial walls that contained continuous insulation, the walls ties were found to have a minor impact on the overall thermal performance. Wall systems with significant thermal mass, such as brick veneer, have better performance under dynamic thermal loading, which is not reflected in steady-state measurements. This paper focused on steady-state worst-case results, and future work will address dynamic performance.
The Effect of Slot Length on Masonry Stresses in the C1197 Flatjack Test and the Use of the Ka Reduction Factor
Authors: Citto Carlo A. , Harvey Donald W.
Published: January 2023

The flatjack deformability testing described in ASTM C1197 has been used effectively for over 25 years to evaluate compressive stiffness and strength of in situ masonry assemblies. The test method is used most frequently at historic masonry structures where the mechanical properties of the masonry are unknown. The test involves cutting vertically aligned horizontal slots into the masonry assembly, inserting hydraulic bladders (flatjacks), and inflating these bladders while monitoring displacement of the masonry. This procedure produces a stress-strain curve that can be used to determine the assembly stiffness and often its strength. In the current standard, the pressure applied by the flatjack is adjusted by an area reduction factor, Ka. This factor effectively reduces the calculated pressure applied by the flatjack by the ratio of the flatjack surface area to the area of the slot. This reduction factor assumes that the pressure from the flatjack will be spread evenly over the slot area, both through the wall thickness and along the slot length. If the area reduction factor is analyzed for an extreme condition, cutting a slot two times the length of the flatjack will result in calculated compressive stresses in the test area of one-half the magnitude of the stresses under the same pressure with a tightly fitted slot. Clearly, this would not be the case. The length of the slot can reasonably be expected to have some impact on stress levels near the edges of the test specimen, but the effects of longer slots on stress levels near the center of the test area are less obvious. This paper describes the numerical results of the finite element model analysis associated with parametric studies of slot length and displacement measurement locations for ASTM C1197 testing. Recommendations for modifications to the Ka factor are also provided.
A Look to the Past: Reevaluation of the Performance of Tall Slender Concrete Masonry Walls

Published: January 2023

Slender masonry walls (SMWs) with a slenderness ratio (kh/t) over 30 have stringent design requirements in North American codes (TMS 402/602-16; CSA S304-14). As a result, in some design scenarios masonry struggles to be a competitive option compared to other systems. The limits and requirements for tall walls are largely based on a comprehensive investigation conducted by the American Concrete Institute and the Structural Engineers Association of Southern California 41 years ago. Since then, understanding of these slender elements has advanced, and the tools for a more refined analysis have become easily available to practicing engineers. Furthermore, recent studies highlight the need to reevaluate the performance of these walls and the requirements in the design standards. In this study, a full-scale SMW built using concrete masonry units subjected to eccentric axial and cyclic out-of-plane loads was tested, the first of a series of tests conducted at the University of Alberta to reevaluate the strength and behavior of tall concrete masonry walls; the test aimed to generate a rational design procedure for modern SMWs.

Published: January 2023

Fast and sustainable lunar exploration under the National Aeronautics and Space Administration's Artemis program or commercial efforts will require an affordable, reliable, low-risk approach for reaction control, as demonstrated by the Apollo program in 1969. Fifty years later, in 2019, Aerojet Rocketdyne undertook an advanced propulsion development effort to combine modern additive manufacturing (AM) techniques with scalable hypergolic MON-25 propulsion technology to create a high-performance reaction control system (RCS) at a fraction of the heritage production cost. Newly developed AM processes in titanium and niobium are used to fabricate a near net shape lightweight and efficient “quad” RCS (i.e., four thrusters in a single integrated package). Manufacturing is enabled by advances in industrial metal printing capabilities, such as noncontact recoaters, to produce AM overhangs down to 0°. Cost is lowered by the integration of parts and functions that reduces the bill of materials, touch labor, and assembly time. Affordability is further enhanced when AM also leverages software advancements of the last 50 years. Employing multidisciplinary design and optimization (MDAO) techniques in integrated environments, such as Phoenix Integration's ModelCenter and nTopology, the engineer is able to evaluate complex designs against system requirements within a matter of minutes. This allows for the creation of complex gyroid features and a generative design that could not have been manufactured in the past yet increase performance (e.g., increased thrust to weight). Further utilizing the ModelCenter environment, performance parameters are also easily traded to mission requirements by creating a digital twin anchored to combustion analysis tools and previous bipropellant test experience. This allows the printable additive design to be adaptable and scalable. This paper also details the impact of nTopology MDAO on the final design when structural loads and operational considerations are accounted for beyond combustion performance. Reduction to practice results are presented with the creation of material test demonstrators.
Design and Manufacture of Precast Concrete Formworks Using Polymer Extrusion-Based Large-Scale Additive Manufacturing and Postprocessing
Authors: Bhandari Sunil , Lopez-Anido Roberto A. , Rojas Felipe Saavedra , LeBihan Alan
Published: January 2023

Large-scale thermoplastic polymer extrusion-based additive manufacturing (AM) has been used to fabricate precast concrete formworks. There are some limitations inherent to the large-scale AM process that need to be overcome to design complex, multipart additively manufactured formworks to be used for precast concrete. This research work uses a large-scale polymer composite AM process to manufacture two-part formworks. Postprocessing was used to repair imperfections, create smooth casting surfaces, achieve precise dimensional tolerance, and incorporate assembly mechanisms for multipart formwork. Two biodegradable polymer composites (wood-fiber polylactic acid and wood-fiber amorphous polylactic acid) and a conventional polymer composite (carbon fiber acrylonitrile butadiene styrene) were selected to manufacture four sets of two-part formwork. Design details, including the cellular infill pattern, continuous toolpath, and layer time selection, are presented. Postprocessing and repairs performed on the manufactured formworks to get the required dimensional tolerance and surface smoothness are discussed.

Published: January 2023

In powder bed additive manufacturing part production, test coupons are often printed together with the actual parts. However, the amount of material required for the tensile test coupons based on current standards are large compared with typical powder bed component sizes. The shortest gauge length for rectangular tensile specimens is 25 mm for the ASTM E8/E8M subsize specimen 6 mm wide. In this work, a scaled-down version of the subsize specimen 6 mm wide with a gauge length of 12.5 mm was tested in a commercially available universal testing frame. The tensile results of this specimen were validated against the standard specimen using clip-on and video extensometers. The thickness range and width tolerance range of the specimen was also investigated. The usage of this specimen was demonstrated in capturing the orientation effects on tensile properties in a laser powder bed fusion machine.
Designing effective knowledge transfer in an organisation - a case study based on migration projects implemented in two SSC organisations
Authors:   Wyższa Szkoła Bankowa w Poznaniu, Tomala Anna
Published: January 2023

This article deals with the subject of knowledge transfer in an organisation, with particular emphasis on the description of tools used for knowledge transfer, as well as the possibility of using theoretical models to design effective knowledge transfer in organisations, such as shared services centres (SSCs). The main objectives of this research were to identify knowledge transfer tools used in SSC companies and check the possibility of using the Knowledge to Action (KTA) model to design effective knowledge transfer in an organisation. The analysis was based on qualitative research carried out in two SSC organisations, with the results showing that both organisations use a variety of knowledge transfer tools, such as in-house training or development programmes using new technologies, and confirmed that the KTA model can be used to design the knowledge transfer process. As the data analysis shows, the human factor plays a very important role in the transfer of knowledge - primarily the skills of people involved in the transfer of knowledge and their motivation to transfer it and share it with other employees. The obtained results can be treated as an indication for organisations in the area of knowledge management, and in particular in the field of designing effective knowledge transfer. Creating an effective knowledge management strategy allows a company to retain knowledge, and as a result contributes to strengthening its market position.

Published: January 2023

The rapidly advancing digitisation and modernisation of information technologies are an impulse to use innovative solutions proposed by the broadly understood financial sector. The presented work presents the development of the banking system in Poland, the perspective of the FinTech phenomenon, with focus on operating bank branches in Poland, as well as innovative solutions. The aim of the article is to analyse the impact of FinTech development on traditional branches of banking institutions in Poland. The authors look at today's behavior of bank account holders with regard to everyday activities, such as withdrawing cash. At the same time they make suggestions as to the reason for the presented results, in order to clearly formulate the final conclusions. The authors also discuss areas analogous to the main topic, such as cashless payment methods, with a closer analysis of their real impact on the banking structure. The main source of information for this article are results obtained from the authors' own research. The considerations lead to the conclusion that in today's banking environment bank branches are somewhat unnecessary and unprofitable, and will slowly decrease in number year by year. The results of the study highlight the amazing BLIK phenomenon, which is increasingly replacing payment methods offered by banks.

Authors:   Uniwersytet Gdański, Müller Marta
Published: January 2023

Nowadays, a challenge faced by all entrepreneurs is acquiring the ability to function in the reality of recurring economic crises, while at the same time obliging company management entities to verify the current methods of operation and their effectiveness in terms of crisis resilience. The purpose of this article is to present a created model of organisational culture characterised by a high degree of resilience to crisis, and then to demonstrate the possibility of its application in economic reality by entrepreneurs and stakeholders. The research process focuses on demonstrating the interdependencies between selected cultural features (dependent variables) and crisis resilience (dependent variable). As part of the model, the most important features of organisational culture have been distinguished, understood as the basic predictors of the resilience of organisational culture to crisis, such as: customer orientation, employee trust, transparency of activities, employee well-being, supporting managerial staff, creativity, employee loyalty, respect for others. The use of the model boils down not only to enabling verification of whether the current organisational culture of a given company can be considered resilient, but also indicates the direction of changes (desired culture) in the case of the willingness to transform in terms of shaping the culture of an organisation aiming at a culture of resilience.

Authors: Kozyr Svitlana V. , Molokanova Valentina M.
Published: January 2023

The article aims to present a method of specialties cases management based on models of system evolution within the frame-work of a pilot projectin institutions of professional pre-higher and higher education of Ukraine for the training of specialists in the dual form of education. The obtained data allowed determining that the methodology of project management can be successfully implemented in Ukrainian dual education. However, the Ukrainian system of dual education still lacks many elements, and some of them cannot be reproduced in the national environment, because the student himself can choose a form of education. The article pre-sents a simulation of the dual education system evolution in a specific specialty in the form of a multicriterial optimization problem. Well-known McKinsey model is adapted to determine the variant of the strategy for managing the dual education system. With the help ofsuch model, the specialties of the educational institution were ranked as candidates for investment according to the criterion of future profit. The trajectory of the specialty evolution has been developed by means of the method for assessing of qualitative factors, such as the attractiveness of the labor market and the competitive status of the educational institution. The inclusion of the specialty evolution trajectory in the integral criteria of the McKinsey model, made it possible to not onlyestablisha competitive sta-tus for the current period, but also extrapolate it without significant changes to the entire strategic period to predict the competitive status of a particular specialty. It is proposed to apply a decision support system based on the useof an apparatus of fuzzy sets and fuzzy logic to formalize decision-making in an intelligent system. The using of the fuzzy logic apparatus made it possible to adjust and clarify the strategic positions of each business unit of the dual education project portfolio. Thus, a significant practical effect was obtained, since the using of this fuzzy system allows to quickly assessingthe forecast positions of dual education projects, to evaluate the future competitive status of the educational product and the management strategy of this project.

Published: January 2023

Tumour microenvironment has been recognized as a crucial factor influencing disease progression. However, relevant features and functions are insufficiently understood in parathyroid neoplasia. Single-cell RNA sequencing was performed to profile the transcriptome of 27,251 cells from 4 parathyroid adenoma (PA) tissue samples. External transcriptomic datasets and immunofluorescence staining of a tissue microarray were set for expression validation. Eight major cell types and various subpopulations were finely identified in PA. We found that a subcluster of tumour endocrine cells with low copy number variation probably presented as a resting state. Diverse infiltrating immune cell subtypes were identified, constructing an immunosuppressive microenvironment. Tumour-associated macrophages, which indicated an anti-inflammatory phenotype, were significantly increased in PA. Inflammatory tumour-associated fibroblasts (iTAFs) were newly verified and highlighted on the role of stromal-immune crosstalk. Positive correlation between iTAFs and increased CD163+ macrophages was uncovered. Moreover, CXCL12 receptor signalling is important for tumour angiogenesis and immune infiltration. Our findings provide a comprehensive landscape interpreting tumour cell heterogeneity, cell diversity, and immune regulation in parathyroid neoplasia. The valuable resources may promote the understanding of parathyroid tumour microenvironment.
Modulatory role of mTOR in trophoblast adaptive response in the early stage of placentation in sheep

Published: January 2023

During the early stage of placentation in sheep, normal conceptus development is affected by trophoblast cell functionality, whose dysregulation results in early pregnancy loss. Trophoblast metabolism is supported mainly by histotrophic factors, including fibroblast growth factor-2 (FGF2), which are involved in cell differentiation and function through the modulation of specific cellular mechanisms. The mechanistic target of rapamycin (mTOR) is known as a cellular ‘nutrient sensor’, but its downstream regulation remains poorly understood. The hypothesis was that during trophoblast development the FGF2 effect is mediated by mTOR signalling pathway modulation. Primary trophoblast cells from 21-day-old sheep placenta were characterised and subjected to FGF2 and rapamycin treatment to study the effects on cell functionality, gene and protein expression profiles. The model showed mainly mononuclear cells with epithelial cell-like growth and placental morphological properties, expressing peculiar trophoblast markers. FGF2 promoted cell proliferation and migration under normal culture conditions, whereas mTOR inhibition reversed this effect. When the mTOR signalling pathway was activated, FGF2 failed to influence invasion activity. mTOR inhibition significantly reduced cell motility, but FGF2 supplementation restored motility even when mTOR was inhibited. Interestingly, mTOR inhibition influenced endocrine trophoblast marker regulation. Although FGF2 supplementation did not affect ovine placenta lactogen expression, as observed in the control, interferon-tau was drastically reduced. This study provides new insights into the mechanism underlying mTOR inhibitory effects on trophoblast cell functionality. In addition, as mTOR is involved in the expression of hormonal trophoblast markers, it may play a crucial role in early placenta growth and foetal–maternal crosstalk.

The nanocomposites based on polyurethane matrix and multicomponent polymer matrices consisting of polyurethane and poly(hydroxypropyl methacrylate) with different contents of the last, and 1,2-propanediolisobutyl polyhedral oligomeric silsesquioxane (1,2-propanediolisobutyl-POSS), which was used as a functionalized nanofiller, were synthesized. The influence of the content of 1,2-propanediolisobutyl-POSS on intermolecular interactions and structural features of the nanocomposites was investigated by the method of IR-spectroscopy with Fourier transformation and attenuated total reflection (FTIR-ATR). The study of thermal curing of the model system, which consists of the adduct of trimethylolpropane with toluene diisocyanate and 1,2-propanediolisobutyl-POSS, made it possible to conclude that 1,2-propanediolisobutyl-POSS participates in the reaction of urethane formation using of one of the terminal hydroxyl groups, and it is incorporated into the polymer chain between cross-linking of polyurethane networks. The investigation of multicomponent polymer matrices by FTIR-ATR spectroscopy was done and was shown that photopolymerization of second polymer poly(hydroxypropyl methacrylate) in the matrix of polyurethane was completed by the opening of a double bond and the formation of a linear polymer in the composition of semi-IPN. Studies of nanocomposites based on multicomponent polymer matrices consisting of polyurethane and poly(hydroxypropyl methacrylate) with 15 and 30 % of the last by FTIR-ATR spectroscopy demonstrated the presence of POSS in the nanocomposites and the influence of POSS content on the structure of the studied systems and on the degree of phase separation. The POSS is "embedded" into the polymer chain between cross-linking of the polyurethane networks, with the additional formation of a complex system of intermolecular hydrogen bonds between the carboxyl and amine components of urethane groups in the nanocomposites.
Ukrainian language policy in the 1920s and after 1991: Development stages and present trends
Authors:   University of Macerata, Orazi Laura
Published: January 2023

This article is an attempt to offer a survey of the language policy adopted in Soviet Ukraine in the 1920s and in contemporary Ukraine after 1991 highlighting the crucial notion of language as a national treasure for Ukrainian identity. First of all, the Romantic or German model of ‘nation’ is discussed. The paper also deals with the main premises, choices, and outcomes of the ‘Ukraini zation’ language policy of the 1920s: although the Bolsheviks considered language as a mere tool, noteworthy results were achieved in education, print media, and, to a lesser extent, among the officials. After 1991, Ukrainian language policy faced the complexity of a formal definition of the status of the Ukrainian and Russian languages, as well as a need for the reaffirmation of the state language (Ukrainian) in the spheres previously dominated by the Russian language. The 2012 lan guage law represented a new form of Russification, whereas the 2019 language law focused more on the needs of the Ukrainian society, and promoted a new ‘Ukrainization’ in the spheres of public administration, media, and science.

Formation of the language identity of the residents of Central and Southern Ukraine in the conditions of tricodalism (Ukrainian Language – Russian Language – Ukrainian-Russian mixed speech)
Authors:   Carl von Ossietzky University of Oldenburg, Germany, Palinsʹka Olesia
Published: January 2023

This article aims to analyze the features of linguistic socialization and formation of the language identity of the residents of central and southern regions of Ukraine, which are normally considered as a territory of Ukrainian-Russian bilingualism and Ukrainian-Russian code-mixing, i.e., so-called Surzhyk. The relation between the dominant language of the respondents and the factors of formation of their speech competence is described in four contexts as follows: 1) a parent’s language and communication in a family; 2) a close environment language; 3) a school language; 4) a language of books, television, and the Internet. Being conducted on the basis of sociolinguistic data obtained from the 2014—2020 survey in the region and semi-structured in-depth interviews with mixed-language speakers, the research combines quantitative and qualitative research methods. In families, respondents mostly use their main language with their children. In Ukrainianspeaking families, there is a partial shift toward mixed speech (Central Ukraine) or Russian (Southern Ukraine). In Russian-speaking families, this shift is toward Ukrainian with respect to mixed speech. The influence of the school language on respondents’ speech shall be differentiated. While the school language is quite significant for the skills formed during school education, e.g., reading and writing, it much less determines the choice of the respondents in their everyday speech. The peer environment also defines the development of children’s/teenagers’ speech competencies. According to the respondents, Ukrainian prevails in peer groups. This is determined by a number of factors, e.g., the spread of Ukrainian-language education and preschool education, the increasing number of books in Ukrainian, television products and Internet content in Ukrainian, the increasing use of Ukrainian in culture, and public services. Keywords: language socialization, language identity, Ukrainian-Russian code-mixing
The local dialect of Zaderi¿vka (Ñhernihiv region) in the east Slavic context
Authors:   Institute of Philology, Borys Hrinchenko Kyiv University, Gaudio Salvatore Del
Published: January 2023

Chernihiv) represents a minor segment of a larger research project devoted to the study of the local dialects spoken in the uttermost northwestern area of the region of Chernihiv. These dialects, according to a largely accepted classification, are attributed to the northeastern Ukrainian (or Polissian) dialectal territory and are more specifically known as “transitional from Ukrainian to Belarusian”. Because of the predominantly descriptive character adopted in this paper, some theoretical implications and debatable issues will not be discussed here. The most significant geo-historical facts about this rural village, in line with the dialectological practice and the methodology applied for the collection of data, are delineated in the introductory sections. Central to this study is the description and analysis of the most substantial dialectal features of this local dialect. Their characteristics are examined considering the usual linguistic parameters: phoneticphonology, derivation (to a minor extent), morphology, syntax, and lexis. The fact that Zaderi¿vka is reported (point number 65) in the Atlas Ukraїns’koї Movy [Atlas of the Ukrainian Language] favours comparison with other local varieties, and it is useful to identify recent trends and possible undergoing changes in the examined dialect. The dialectal data analyzed in this paper aim, on the one hand, to increase the already available factual material and, on the other, to foster further theoretical reflections about the origin of these border dialects. Keywords: East Slavic dialectology, North Ukrainian (East Polissian) dialects, Zaderiїvka, local dialect, border dialects

ABSTRACTThis study aims to find out the use Google Meet Automatic Caption feature to assist teachers of non-native English to assess their students' English pronunciation. We used a mixed-method with the explanatory-sequential approach following it. This research study was done at Tidar University with 12 participants, further reduced to 4 in the participant selection step. As the data were both quantitative and qualitative, we used the Word Error Rate (WER) formula quantitatively and Qualitative Content Analysis qualitatively. The findings show that Artificial Intelligence (AI) has a very sensitive system in transforming sounds into written forms. It also has an auto-correction system that sometimes can substitute a word with a meaningless one if a speaker pronounces the word unclearly or to the nearest word if a speaker mispronounces it. Even though it does not accurately process the punctuation and there is no sufficient correction on grammar, we believe the AI can help teachers in a pronunciation assessment.ABSTRAKPenelitian ini bertujuan untuk mengetahui penggunaan fitur Teks Otomatis pada Google Meet untuk membantu para guru Bahasa Inggris bukan penutur asli saat menilai pengucapan bahasa Inggris siswa mereka.

BACKGROUND AND OBJECTIVES

Acute hematogenous musculoskeletal infections (MSKI) are medical emergencies with the potential for life-altering complications in afflicted children. Leveraging administrative data to study pediatric MSKI is difficult as many infections are chronic, nonhematogenous, or occur in children with significant comorbidities. The objective of this study was to validate a case-finding algorithm to accurately identify children hospitalized with acute hematogenous MSKI using administrative billing codes.

METHODS

This was a multicenter validation study using the Pediatric Health Information System (PHIS) database. Hospital admissions for MSKI were identified from 6 PHIS hospitals using discharge diagnosis codes. A random subset of admissions underwent manual chart review at each site using predefined criteria to categorize each admission as either “acute hematogenous MSKI” (AH-MSKI) or “not acute hematogenous MSKI.” Ten unique coding algorithms were developed using billing data. The sensitivity and specificity of each algorithm to identify AH-MSKI were calculated using chart review categorizations as the reference standard.

RESULTS

Of the 492 admissions randomly selected for manual review, 244 (49.6%) were classified as AH-MSKI and 248 (50.4%) as not acute hematogenous MSKI. Individual algorithm performance varied widely (sensitivity 31% to 91%; specificity 52% to 98%). Four algorithms demonstrated potential for future use with receiver operating characteristic area under the curve greater than 80%.

CONCLUSIONS

Identifying children with acute hematogenous MSKI based on discharge diagnosis alone is challenging as half have chronic or nonhematogenous infections. We validated several case-finding algorithms using administrative billing codes and detail them here for future use in pediatric MSKI outcomes.

Hydroxyapatite (HA) is an alloplastic material that is commonly used as a substitute for bone grafts or bone grafts because it has bioactive properties, namely osteoconduction. This study aims to improve or develop the function of hydroxyapatite to become a strong and resilient biological device that can withstand loads for appropriate functions such as bone implants. Therefore, it is necessary to modify the structure, among others, by the reinforcement process (composite formation) with other materials.The doping of hydroxyapatite/Al2O3 in this study was carried out using the hydrothermal method. The hydrothermal method is one of the hydroxyapatite synthesis methods carried out at high pressure and temperature to achieve equilibrium. The material used in this study was papai shrimp as a source of calcium. The temperature has an effect in this study where the higher the doping temperature used, the higher the degree of crystallinity, particle size homogeneity, and porosity value. From the doping results, it is known that a temperature of 300°C produces a degree of crystallinity of 54.32% and a crystal size of 3.75 nm with a porosity value of 99.38%. This result is much better than the undoped hydroxyapatite in the previous study.

Currently in Indonesia, propellant research is still rarely carried out due to bureaucratic and budgetary problems. This study aimed to determine the optimum composition of propellant using local sources of nitrate compounds based on its combustion heat value and to study the effect of the composition on its combustion heat value. The propellant composition used in this study consists of oxidizing agents (local nitrate compounds), fuel (Aluminium), binder (polyester-based resin), and additive (catalyst). A bomb calorimetry method (ASTM D5865/5865-19) was used to determine the combustion heat value of the propellant. The results showed that the heat of combustion of local content nitrate compound-based propellants was high (> 1500 cal/g), adding binder to the propellant composition increases the heat of combustion. Ammonium nitrate-based propellant has the highest heat of combustion value of 3,788 cal/g. The optimum binder composition in the propellant was 33% (w/w). Based on this study, local source of nitrate compounds has potential to be used for development of propellant, especially in Indonesia. Therefore, it can encourage rocket research in Indonesia as a capital for the development of defense equipment to be less expensive.

Published: January 2023

The modern Islamic movement is a movement that existed in the early 20th century. This term is often used to describe the change in life systems from the traditional Islamic system to a more modern system. This movement is characterized by Islamic activities through modern organizations, newspapers, modern education, new ideologies and re-questioning the position of women in religion. Arabs living in the Dutch East Indies participated in the process of this movement, especially in Solo in the early 20th century. Therefore, this paper aims to explain how the process of the modern Islamic movement carried out by Arabs in Solo in 1912 -1942. This study uses historical methods, sociological approachment, and modernitation theory. The results of this study indicate that Arabs in Solo were initially involved with the local movement in 1912-1930. Then After "hitting" with the local movement, Solo Arabs took part internally among themselves which was marked by the PAI movement in 1934-1942.
Sacrum w twórczości Janusza Szubera

Published: January 2023

Janusz Szuber was considered by some to be a local poet, but it is now known that he is part of the canon of writers belonging to outstanding authors of contemporary Polish literature. He created poetry in such a way that the reader could not only get to know the reality in which the author lived, but also was introduced to a world full of the spirit of philosophy, deep intellectualism and language virtuosity. The sacral sphere in Szuber’s poetry is, first of all, where life itself is found as the time that has been given to him and the environment in which he lived. The author, although disease-stricken, does not complain about his fate; on the contrary, he appreciates this experience as it allows him to reflect more deeply on the condition of man in the world. His poetry, devoid of moralizing, is unusual because it shows how to look at one’s own existence in order to be a happy person.
„Antywyraizacja” w [„Dziadach”] Juliusza Słowackiego
Authors:   Uniwersytet Warszawski,Polska, Hanuszewicz Zuzanna
Published: January 2023

The author of the paper aims to indicate a new way of interpreting Juliusz Słowacki’s [“Dziady”] by using a new aesthetic-literary trend known as the Slavic anti-twist. So far, literary scholars have analyzed this dramatic fragment mainly from the genesis perspective or the antagonism of the bards. They believed that through the greatest works of Adam Mickiewicz, such as “Dziady”, “Pan Tadeusz” and “Konrad Wallenrod”, Słowacki expressed his own mystical intentions. During the period of [“Dziady”] creation, the poet was keenly interested in the Slavic culture, references to which often appeared in his genesis texts. The situation is similar with [“Dziady”] where one can find elements of the Slavic anti-subjugation.
