Published: June 2024

The study focuses on utilizing digital technologies within the context of preschool education in the Czech Republic, as viewed through the lens of kindergarten teachers. The objective was to find out teachers' perspectives on using digital technologies with a focus on language development in preschools from the point of view of Czech teachers. The survey method was used for data collection. Responses were collected from 80 preschool teachers from the Czech Republic using an online questionnaire; data was analyzed and discussed quantitatively in descriptive analysis. The study revealed that preschool establishments demonstrate a relatively commendable level of digital technology provisioning, which has grown recently with the help of financial subsidies from the government. However, teachers state that there is a lack of management support for effectively integrating them into the curriculum. The survey revealed that they also have to deal with the organizational arrangements of children when using digital technologies, given the number of children in classes. In our study, we paid special attention to areas of language competence that had developed. It was found that teachers prefer applications with simple language development competencies as opposed to complex language skills. They also prefer to use applications that children can use independently. In conclusion, teachers mostly have a positive attitude towards their utilization, under the condition of limiting their use in time and type of content.

The production of a standard and reproducible experimental mode of peripheral nerve injury, has been a long-time quest in nerve regeneration research. The aim of this pilot study was to reproduce sciatic nerve crush injury model in Wistar rats and also use the established method for broader and future research. Materials and Methods: twenty (20) rats grouped into five (5) of five (5) rats each. Normal control (G1), the sciatic was not exposed nor crushed; Sham (G2), the sciatic nerve were surgically exposed but not crushed; Crushed (G3), the sciatic nerve were surgically exposed and uniformly crushed, using a non-serrated heamostatic forceps that exerted a compressive force of 33N for a duration of 30 seconds and Transected (G4), the sciatic nerve were exposed and completely transected. Sciatic nerves were harvested at seven (7) days (post-injury) for histological evaluation and the groups were compared for histopathological changes. Results: Transverse sections of toluidine blue (TB) stained sciatic nerve micrograph, showed degenerative changes in the axons, myelin ballooning and surveiling white blood cells, all of which were consistent with Wallerian degeneration in G3, when compared with groups G1 and G2. The G4 group showed more severe degenerative changes when compared with group G3. Conclusion: The histopathological analysis suggest that the modified induction method used in this study, caused Axonotmetic lesion in the crushed sciatic nerves of the Wistar rats.

External and Internal Attribution in Human-Agent Interaction: Insights from Neuroscience and Virtual Reality
Authors: Lauharatanahirun Nina , Wom Andrea , Hwang Angel
Published: June 2024

Agents are designed in the image of humans, both internally and externally. The internal systems of agents imitate the human brain, both at the levels of hardware (i.e., neuromorphic computing) and software (i.e., neural networks). Furthermore, the external appearance and behaviors of agents are designed by people and based on human data. Sometimes, these humanlike qualities of agents are purposely selected to increase their social influence over human users, and sometimes the human factors that influence perceptions of agents are hidden. Inspired by Blascovich’s “threshold of social influence’, a model designed to explain the effects of different methods of anthropomorphizing embodied agents in virtual environments, we propose a novel framework for understanding how humans’ attributions of human qualities to agents affects their social influence in human-agent interaction. The External and Internal Attributions model of social influence (EIA) builds on previous work on agent-avatars in immersive virtual reality and provides a framework to link previous social science theories to neuroscience. EIA connects external and internal attributions of agents to two brain networks related to social influence. the external perception system, and the mentalizing system. Focusing human-agent interaction research along each of the attributional dimensions of the EIA model, or at the functional integration of the two, may lead to a better understanding of the thresholds of social influence necessary for optimal human-agent interaction.

Kedun (National Technical University "Kharkiv Polytechnic Institute", 2, Kyrpychova str., Kharkiv, 61002, Ukraine) The article shows that ensuring energy security requires an integrated approach, including the search for and implementation of new sources of boiler fuel. Coke production and pyrolysis of coal coking by-products are among the promising areas that can balance the requirements of energy efficiency and environmental sustainability and can play a key role in ensuring a sustainable energy future for Ukraine. It has been demonstrated that intermediate products obtained in the process of coke production represent a promising source of furnace fuel. The development of new formulations allows not only to increase energy efficiency but also to reduce the negative impact on the environment. The pyrolysis of secondary resources opens up opportunities for expanding energy sources, which is becoming a key aspect of ensuring the energy security of the state. Relevant studies are highlighted. A sample of coal tar, which is not used for the production of electrode pitch grades in coke production, and pyrolysis liquid formed in the process of recycling rubber car tyres were taken for their analysis. The compatibility of these materials was assessed based on the presence or absence of sediment at the bottom of the container after thermostatting. The results showed that the compatibility of pyrolysis fluid and coal tar is quite low, with the maximum co-dissolution observed when mixing 20 % pyrolysis tar and 80 % coal tar. The flocculation coefficient was determined to be 0.7 units. This characterises the system as more prone to sedimentation. The inapplicability of the formula for calculating oil incompatibility (API MPMS 12.3) indicates a different mechanism of solvation of coal and pyrolysis resins than that of petroleum materials. Keywords: coal tar, boiler fuel, quinoline insoluble substances, pyrolysis liquid, compatibility, solvation. Corresponding author T.M. Kedun, e-mail: tatanakedun07@gmail.com
Children's evaluations of empathizers
Authors: Smith-Flores Alexis Sierra , Bonamy Gabriel , Powell Lindsey J
Published: June 2024

Children’s evaluations of empathizers were examined using vignette-based tasks (N = 159 4- to 7-year-old U.S. children, 82 girls). Similar to adults, children typically evaluated empathizers positively compared to less empathic others. They rated empathic responses as more appropriate, selected empathizers as nicer, and inferred positive relationships between empathizers and the targets of empathy. However, when empathy was contrasted with helping behavior, or when empathy was directed toward an immoral actor, children’s evaluations of empathy were more negative. Older children weighed helping and empathy more equally and shifted their evaluations more when considering responses to immoral acts. These results show that children use empathy in their social evaluations and that contextual influences on these evaluations strengthen with age.
Modeling Dependent Group Judgments: A Computational Model of Sequential Collaboration
Authors: Mayer Maren , Heck Daniel W.
Published: June 2024

Sequential collaboration describes the incremental process of contributing to online collaborative projects such as Wikipedia and OpenStreetMap. After an initial entry is created by a first contributor, subsequent contributors create a sequential chain by deciding whether to adjust or maintain the latest entry which is updated if they decide to make changes. Sequential collaboration has recently been examined as a method for eliciting numerical group judgments. It was shown that in a sequential chain, changes become less frequent and smaller, while judgments become more accurate. Judgments at the end of a sequential chain are similarly accurate and in some cases even more accurate than aggregated independent judgments (wisdom of crowds). This is at least partly due to sequential collaboration allowing contributors to contribute according to their expertise by selectively adjusting judgments. However, there is no formal theory of sequential collaboration. We developed a computational model that formaluzes the cognitive processes underlying sequential collaboration. It allows modeling both sequential collaboration and independent judgments, which are used as a benchmark for the performance of sequential collaboration. The model is based on internal distributions of plausible judgments that contributors use to evaluate the plausibility of presented judgments and to provide new judgments. It incorporates individuals’ expertise and tendency to adjust presented judgments as well as item difficulty and the effects of the presented judgment on subsequent judgment formation. The model is consistent with previous empirical findings on change probability, change magnitude, and judgment accuracy incorporating expertise as a driving factor of these effects. Moreover, new predictions for long sequential chains were confirmed by an empirical study. Above and beyond sequential collaboration the model establishes an initial theoretical framework for further research on dependent judgments.

In area mining are quite extreme, where the level of safety from high temperatures and toxic gases which are explosive as well as well flow pressure is also high and can damage production equipment. Therefore, it is very necessary to install reliable electrical power, starting from analyzing the selection of cable types that used, voltage drop, power losses and transformer selection. The problems mentioned previously, this research carried out an analysis of improvements to voltage drops and power losses that occurred in the ESP motor installation system. The method used is to replace the type of cable used in three scenarios with three different types of cable. The installation system data obtained from this company was then processed using software which was then validated with theoretical calculation results. The result of voltage drops and power losses in ESP cables according to standards using scenario 3, replacing AWG 2/0 type with a voltage rating of 5 kV, diameter of 11.709 mm and has a KHA of up to 210 A. The voltage drop value after repairs are carried out based on theoretical calculation results has an average percentage index value of 4.5% and power losses of 4.6%. This shows that in the condition after repairs, both the results of simulation calculations and theoretical values have met the IEEE std 141-1993 standard which states that the value of voltage drop and power losses in industrial plan distribution systems must be below 5%.

Authors: Bhusal Gaurav , Koirala Badal , Kharbuja Sunita
Published: June 2024

Plastic is everywhere, and its use in different forms is increasing day by day despite discouragement from the government. Plastic waste disposal is a global issue since they are non-biodegradable and toxic in burning. Plastic pollution threatens food quality, human health, sanitation, and the ecosystem and contributes to climate change. The usage of plastic waste in elements (bitumen and aggregate) used in road construction was the main objective of this study. With use of appropriate plastic waste in building of road would not only reduce material cost but also contributes in solving plastic waste management issue. Nepal being a developing country with low Gross Domestic Product (GDP) where most of the districts are still deprived of good flexible pavement networks, plastic modified roads could be a value engineering and economic solution. The paper highlights by which method plastic waste can be used effectively in road construction by performing different experimental tests reflecting the characteristics of bitumen and aggregate on addition of plastic. The study has determined the penetration, softening point, ductility values of bitumen and impact and abrasion values of aggregate in addition to different percentage of plastic waste. According to the study, bitumen's penetration and ductility value drop with increasing plastic content, making it better suited for usage in warmer climates, but its softening point rises, ensuring a stronger resistance to flow in services. Comparably, when in aggregate plastic content rises, both its AIV value and its LA abrasion value fall, enhancing the aggregate's toughness and ability to endure greater wear and tear.

The majority of Nepal’s National Highway and feeder road system comprises two-lane highways with heterogeneous traffic conditions. Factors such as lane width, gradient, lateral clearance, and shoulder conditions can influence the passenger car unit (PCU) and roadway capacity. Recognizing that grade magnitude (%) is an important yet unexplored roadway factor in Nepal, and the present study primarily aims to estimate the passenger car unit on two-lane undivided hilly roads with gradients under prevailing heterogonous traffic conditions.
This study aims to determine the PCU values and roadway capacity at grade under mixed nature traffic flow for a two-lane undivided highway. In this research, the necessary data were collected at five sections of BP highways using a digital video recorder, which was then analyzed to assess traffic characteristics and calculate PCU values. Using the PCU values, the road capacity was estimated using Greenshield’s model. For capacity estimation, flow and density were addressed using dynamic PCU values.
This study reveals that the PCU of all categorized vehicles increases linearly with the increase in gradient while roadway capacity decreases with an increase in grade. It was observed that PCU values obtained for two-wheelers in all sections are smaller than the PCU values specified in NRS 2013, whereas for buses, trucks, and LCVs, they are higher than the PCUs given in NRS 2013. The study highlights the impact of road grade on the PCU for different vehicle categories on a highway. Additionally, the study demonstrates that the developed capacity values are realistic and consistent with the values presented in the Highway Capacity Manual (HCM) of developing countries such as Indonesia and China. These results are expected to be beneficial for practitioners and the ongoing effort to develop a highway capacity manual.

Authors: Limbu Binod , Chaudhary Birochan Kumar , Jha Suraj Kumar
Published: June 2024

This is a literature review on the role of serum vitamin D levels in dengue viral illness as a potential immunomodulator. The dengue virus is an RNA virus that causes many symptoms, from asymptomatic phases to severe forms like dengue hemorrhagic fever and dengue shock syndrome. The review methodology was based on evidence-based rapid review, and the review's objectives are to scrutinize all the available articles on dengue virus and vitamin D from standard databases and literature searches. It was found that there are no specific antivirals for the definitive management of the dengue virus, and vitamin D, with its potential antiviral and immunomodulatory effects, can play a significant role against the dengue viral illness. It was also found that there are limited reviews on the association between dengue virus and vitamin D. The review concludes that there is a possible association between supplementing with vitamin D and lowering the risk of progression to severe dengue viral illness and that regular testing of serum vitamin D levels is highly encouraged during the illness as vitamin D levels get depleted with the progression of the illness.

Purpose: Familial Mediterranean fever (FMF) is the most common inherited autoinflammatory syndrome throughout the world. The most frequent genotype-phenotype correlation is in a certain part of exon 10, especially M694V mutation. There are also a group of patients with non-exon 10 mutations, who have a similar clinical spectrum of the disease. We aim to investigate the genotype-phenotype differences between M694V heterozygote mutations and non-exon 10 mutations.

Materials and methods: Data charts of children (n=431) with FMF from two tertiary hospitals were reviewed. Patients were divided into two groups with regard to having M694V heterozygote or non-exon 10 mutations. Genotype-phenotype features and response to treatment were compared.

Results: There were M694V heterozygote mutations in 128 (29.7%) patients and non-exon 10 mutations in 303 (70.3%) patients. The follow-up period was 54.5 (33-105) months. There was no difference between the age of symptoms onset, the age of diagnosis, and the diagnosis delay time. The family history in patients with M694V heterozygote mutation was statistically positive compared to non-exon 10 mutation group (p=0.001). The symptoms of joint involvement as arthritis and PRAS scores were significantly higher in the M694V heterozygote group (p=0.026 and p=0.001). Additionally, biological agent need due to colchicine unresponsiveness was statistically higher in M694V heterozygote group than group with non-exon 10 mutation (p=0.004).

Conclusion: There is a significant difference between children with M694V and non-exon 10 mutations, even when the M694V mutation is present in one allele only. Family history with FMF, musculoskeletal symptoms, and unresponsiveness to colchicine are main parameters.

Published: June 2024

The unstable yield of agricultural crops arises due to insufficient soil moisture supply at crucial moments of plant emergence and growth, complicating agriculture and exposing it to the risk of crop losses. The purpose of the study is to determine the impact of the soil tillage system and previous crops on the productivity of spring barley plants. This was a long-term stationary experiment (2021-2023) with the application of statistical data processing. The influence of four previous crops was investigated – grain maize (control), soybeans, winter rapeseed, and sunflower – and three main soil tillage methods. It is established that the highest significant moisture reserves in the 0-100 cm soil layer at the sowing period were formed when spring barley was placed after soybeans, exceeding the control variant (grain maize) by 3.2 mm in 2021, 3.6 mm in 2022, and 3.4 mm in 2023, and after winter rapeseed by 8.5 mm, 6 mm, and 5.7 mm, respectively, over the years. The use of shallow no-till cultivation provided an advantage over the control (ploughing) in all years of observation: by 2.2 mm in 2021, 1.8 mm in 2022, and 8.8 mm in 2023. During the sowing period of the studied crop, the control surpassed only surface no-till cultivation by 2.7 mm in 2022. The optimal option should be considered the combination of soybeans as a previous crop with shallow no-till soil cultivation at 14-16 cm, which ensured moisture reserves during the earing period of the crop in 2021 – 75.1 mm, in 2022 – 93.2 mm, and in 2023 – 92.2 mm, and at the time of harvest, these indicators were 60.7 mm, 67.3 mm, and 60.0 mm, respectively. The grain yield of spring barley under this option was the highest in the experiment, averaging 7.26 t/ha, which is 27.3% higher than the control. The results of the study can be used to realise the genetic potential of spring barley plants to form stable productivity
