Authors: Wadwekar Bhagwati , Punniamurthy Rajarajeswary , Srinivasan Renuka
Published: September 2024

: The change in the retinal thickness is the indicator of retinal disease. These changes can be measured with Spectral-domain optical coherence tomography (SD-OCT). This study was conducted to compare the central macular thickness (CMT), retinal nerve fiber layer (RNFL), and ganglion cell inner plexiform layers (GCIPL) thickness using SD-OCT in hypertensive and normotensives.

: All patients with systemic hypertension above the age of 18 years were included in Group A and the age-matched normotensive patients in group B. A history of hypertension was obtained and blood pressure was measured. A standard eye examination and retinal imaging were performed using SD-OCT. The main parameters studied were CMT, RNFL, and GCIPL. An odds ratio and t-test were performed. A probability value of <0.05 is considered significant.

: There were 60 eyes in each group. The mean age in group A was 52.43±10.35 years. The mean standard deviation of the duration of hypertension in group A was 6.41±6.28 years. The mean standard deviation CMT was 251.03±18.25µm and 256.77±15.09µm in group A and B respectively. There was no statistically significant difference in CMT of hypertensive and normotensives. The hypertensive patients had significant thickening of RNFL in the nasal quadrant compared to normotensive individuals.

: The present study supports the concept that CMT is less likely to be influenced by systemic HTN. RNFL thickness may increase in hypertensives compared to normotensives.

Published: September 2024

Eye inflammation has been described as a crucial prominent feature of several rheumatic diseases. Uveitis, conjunctivitis, and episcleritis have been reported in patients with known spondyloarthropathies or may be significant symptoms for the diagnosis of previously undiagnosed spondyloarthropathy.

A hospital-based, cross-sectional, observational study was conducted over twenty-one months, from January 2021 to September 2022. Patients aged more than 18 years with a definitive diagnosis of Spondyloarthropathy, attending the Department of Orthopedics outpatient clinics, SGMH, Rewa, were screened for presence of eye disorders.

A total of 100 cases were recruited in the study. The mean age of the study group was 34.58 years (female 33.5 years and male 35.6 years) with a majority of cases (72%) in the study group aged between 20 and 39 years. Ankylosing spondyloarthropathy was the most common diagnosis in the study, with 49% cases being diagnosed with it. Patients with Psoriatic arthropathy were also found to have a significant association with foreign body sensation and diminution of vision while ciliary congestion was significantly associated with ankylosing spondylitis. In addition, uveitis was observed to have a statistically significant association with incidence of ankylosing spondylitis.

The various manifestations of seronegative spondyloarthropathies include uveitis, which is a potentially blinding complication was noted in 19% of the patients, that needs to be identified early and treated right away to avoid irreparable vision loss.

Authors: Qayum Shazia , Jabeen Asma
Published: September 2024

Welders are at risk of developing dyschromatopsia, a color vision deficiency, due to occupational exposure, including welding arcs. This visual impairment can impact occupational safety and performance but has received limited attention in research.

: This study aimed to investigate the prevalence and characteristics of defective color vision among welders exposed to welding arcs.

A cross-sectional study was conducted with 52 male welders working in various industries. Demographic and occupational data were collected through a questionnaire. Color vision assessment was performed using Ishihara and Farnsworth Munsell test. Welding exposure data were collected through self-reporting and workplace observations. Chi-square test was used for data analysis. A p-value of less than 0.05 was considered statistically significant.

The prevalence of defective color vision among welders was 15.4%. Age, gender, years of experience, and types of welding performed did not significantly influence the prevalence. Welders in the age group of 31-40 years showed a higher prevalence. Inadequate use of eye protection was identified as a barrier to preventing color vision impairments.

Defective color vision is a prevalent occupational injury among welders exposed to welding arcs. The study underscores the importance of preventive measures, including proper eye protection and education programs, to reduce the risk of visual impairments and improve occupational safety. Further research is needed to understand the long-term consequences of welding arc exposure on color vision and its impact on worker performance.

Published: September 2024

Demand for cleaner energy sources both as additive and alternative fuels that can substitute or contribute to the usage of conventional fuels is growing. Researchers have mainly focused on improving or finding a renewable fuel from vegetable oil or addition of chemicals and alcohols for IC engine. This study analyzed the effects of a high percentage of dimethyl ether (DME) combined with biodiesel in a diesel engine. Transesterification method was selected for conversion of pure safflower oil to biodiesel. DME was blended with biodiesel at concentrations of 50% and 25% on a volume basis, respectively. Engine performance and emissions tests demonstrated that the thermal efficiency values were increased at high load operation when the engine was fueled with high percentage of DME. Furthermore, compared to conventional diesel, there has been a notable decrease in NOx emissions. Nevertheless, the introduction of DME blend had negligible effects on CO2 emissions. However, when using a high ratio of DME blend, HC emissions were found to increase, whereas a low ratio of DME blend resulted in decreased HC emissions. Apart from these, some irregularities were observed both on heat release rate and cylinder pressure especially for 50% of DME usage. Finally, the values for both brake-specific fuel consumption and mass fuel of DME-blended fuels were deteriorated.

Authors: Evdokimov Dmitry
Published: September 2024

The active use of simulation and agent-based models is reaching a fundamentally new level. A study of the development of this area in Russia from the perspective of publication activity was published in a previous paper. An approach using advanced tools provides advantages for developers of management mechanisms. Now, language models that are able to generate answers and solve problems at a high level of complexity are gaining popularity. Such developments are already being used together with an agent-oriented approach, which is of particular interest from the point of view of prospects for applied significance. Scaling of research using such a tool can be adjusted to the desired vector and adjusted to different levels of detail - from individual model objects in the form of entities to parametric features of each individual state along with global changes in the world economy.
The article is based on an overview of various models, which analyzes Russian and foreign developments constructed using the methodology of computer simulation models. This method allows specialists to introduce new approaches into the structure of public administration by analyzing and predicting challenges in various spheres of public life. In addition, popular software for working with models of this class is considered. In another block, a selection of applied models is presented with individual customization for each of the tasks, and demonstration of results that convey the specifics of different spheres of public life, from demographic assessment of the population of countries, planning in the health system to military clashes and ending with software products for analyzing the space situation. Examples are models that study the demographic situation in Russia, the spread of the COVID-19 pandemic, voter turnout, comparison of the armed forces of the parties, etc. In the experimental results of some models, it is possible to identify a social orientation that helps to understand the specifics of demographic and social problems well – population decline, the level of support for the political elite, the behavior of people in a stressful situation, government support measures that have a positive effect on the population.
Towards simulation of artificial societies of agents with a universal coordination instrument
Authors: Parinov Sergey
Published: September 2024

Developing the models of artificial societies with simulation of agents’ joint socio-economic activity a challenging task is to endow the agents with properties allowing them to mutually take into account each other's intentions and activities. The presence of such properties in agents creates conditions for the emergence of social organization in the modeled system, including processes of coordination and governance. In the proposed study, agents obtain the required properties due to their natural ability to create and use shared (collective) mental models under various modes of communication between them. On this basis, the concept of an agent with a universal coordination instrument (UCI) is substantiated. Agents optimize UCI settings to take full account of each other's activities and maximize the benefits of joint activities. UCI with settings is a common information environment for participants in joint activities, as well as a means of determining the optimal content of their joint activities. The main components and functions of UCI as a special type of agent-based simulation model are discussed. The necessary conditions for using the UCI are considered. From the results obtained it follows that individuals with UCI have both substantive and procedural rationality, which leads to the emergence of two types of equilibrium in the socio-economic system.

Knowing the population and habitat conditions of Timor Deer (Rusa timorensis), which is a protected animal, is very important to ensure the survival of this species. One of the most important habitats for Timor Deer is Menipo Nature Park, which must be well managed to support the welfare and sustainability of the species. Good management includes protection of natural habitats, regular population monitoring, and sustainable conservation efforts so that Timor Deer can survive in their natural environment. The purpose of this study was to estimate the population and habitat conditions of Timor deer in Menipo.  The method used is a combination of point and path, while the habitat is described descriptively. From the results of research on the 571 ha habitat area, the population of timor deer was estimated to be 399 individuals with a population range of 366 to 432 individuals at the 95% confidence interval with a population density of 1.14 individuals per hectare. The population structure showed an inverted pyramid, indicating less than optimal conditions in terms of population age distribution. The sex ratio was 2:5 for juveniles, 2:3 for adults, and 1:1 for the old age group. This sex ratio is not good for the timor deer population as 1:5 is good. The most common type of grass for deer is timor grass (Ischaemum timorensis). Other grass species are Microlaena stipoides, Paspalum scrobiculatum, Imperata cylindrical, and Desmodium capitulum shrub.  However, some areas of this habitat are covered by alien invasive species, Cromolaena odorata, which needs to be eradicated to maintain food availability.  Mangrove parts eaten by Timor deer (Rusa timorensis) include young leaves, young stems, and exfoliated bark. Mangrove species commonly found as food for deer include Rhizophora mucronata, Bruguiera parviflora, and Sonneratia alba.

This study develops roselle yogurt ice cream by combining the probiotic benefits of yogurt with bioactive compounds from roselle flowers. Yogurt is produced through milk fermentation by lactic acid bacteria, while roselle flower extract is rich in anthocyanins and flavonoids known for their antioxidant, antibacterial, and anti-inflammatory properties. The research methods included a comprehensive analysis of physicochemical properties, nutritional content, microbiology, antioxidant activity, and organoleptic characteristics. Using a randomized complete design, data analysis employed ANOVA and the Least Significant Difference tests (P < 0.05), with sensory evaluation conducted using the Kruskal-Wallis test. The results of exploring the synergy between roselle yogurt and ice cream in varying proportions (20:80, 30:70, 40:60) showed that the treatment with a 30:70 ratio of roselle yoghurt (P2) was optimal in physicochemical characteristics such as pH 5.47, total titratable acidity 0.74%, overrun 75.61%, and meltdown rate of 26.98 minutes. P2 also exhibited the highest total antioxidant activity at 137 µg/mL, with good sensory acceptance from consumers. This experiment provided an understanding of the potential of roselle yoghurt ice cream as a product that meets increasingly selective consumers' nutritional and health needs. It is hoped that these findings will stimulate the development of ice cream products that are not only commercially popular but also provide significant health benefits.

This study investigates the combined effects of standard soil fertilization, composted animal manure, and foliar fertilization on tomato yield, soil nutrient content, and soil biological properties under greenhouse conditions. The experiment was conducted from March to October 2023 using a completely randomized block design with four replications. The treatments included: 1) Control (no fertilization), 2) Standard soil fertilization (30 kg N/da, 8 kg P2O5/da, 40 kg K2O/da), 3) Standard soil fertilization + composted animal manure (2 t/da), 4) Standard soil fertilization + foliar fertilization (1 kg 17-17-17/100 liters of water every 20 days), and 5) Standard soil fertilization + compost + foliar fertilization. Tomato seedlings (Solanum lycopersicum L. cv. Roma) were transplanted into pots filled with clay soil. Throughout the experiment, soil moisture content was maintained at field capacity. Plants were harvested on October 30, 2023, and data on fruit yield, soil nutrient content (NPK), and soil biological properties (microbial biomass C, CO2 production, and dehydrogenase enzyme activity) were recorded. The highest yield (4.5 kg/plant) was observed in the treatment combining standard soil fertilization, composted animal manure, and foliar fertilization, representing a 275% increase compared to the control (1.2 kg/plant). The standard soil fertilization treatment alone yielded 2.8 kg/plant (133.3% increase), while the combination with composted animal manure yielded 3.5 kg/plant (191.7% increase), and with foliar fertilization, 3.9 kg/plant (225% increase). Soil analyses showed significant increases in available nitrogen, phosphorus, and potassium in the combined treatments. The highest biological properties were also recorded in the combined treatment.

Pro-drop in Farsi: A Case Study of Bilingual Speakers
Authors: Hajian Foroozan , Vargáné Nagy Anikó
Published: September 2024

This research is meant to uncover some of the internal grammatical structure of bilingual Farsi speakers who have English as their dominant language. Bilinguals, whose mother tongue is Farsi but whose dominant language is English, are influenced by their dominant language on their mother tongue concerning pro-drop. One of the issues often seen in bilingual speakers of null subject languages is the use of pro-drop in languages such as Hungarian, Japanese, Chinese, Slavic languages, and Arabic. This paper will demonstrate how these bilingual speakers incorrectly use the null subjects in their sentences and in addition, how SEN children i.e. Autism Spectrum Disorder (ASD) understand and use the pronoun-dropping phenomenon. Choosing a null pronoun in the non-dominant language seems unacceptable to some speakers because their dominant language lacks pro-drop; therefore, in certain situations, researchers might say that these bilingual speakers do not sound as fluent in their native language as they do in their dominant language. The main focus of this research is the investigation into the preference of bilingual speakers as well as ASD children of English and Farsi and their use of pro-drop

Published: September 2024

Anxiety is a prevalent mental health issue among children and adolescents, which can have a detrimental impact on their personal relationships and academic performance. This study aimed to identify the manifestations of anxiety in educational settings, the effects of anxiety on educational activities, and the types of support that should be provided to students with anxiety. The following research questions guided this study:  1) How is anxiety expressed among 13-14-year-old students when in school? 2)How does anxiety affect the 13-14-year-old students' educational activities? 3) What kind of support should be provided to students with anxiety at school? The participants were 26 students aged 13-14 from various Estonian schools. The data was gathered for analysis via interviews and a questionnaire. A mixed-methods approach was employed. According to the research, children experience anxiety both before and during a test or presentation. It appears that each student expresses fear at school in a different way. Students who learn remotely report feeling less anxious during class activities. This is because they do not have to answer in front of the class or turn on the camera when participating in online lessons. Furthermore, students aged 13-14 prefer to talk to their friends who are also experiencing anxiety than to adults who do not understand their anxiety. Finally, the students' answers revealed that the teacher should ask all the students with equal frequency to present their homework. It is also recommended that anxious students be supported by helping them recall what they have learned and use different methods to assess their knowledge. The students stated that they require a quiet and safe place to be alone at school. There is a need to raise awareness about anxiety symptoms and ways for teachers to support students.

The aimof the study is using experimental histological techniques to validate the beneficial potential of specific medical devices made of nanostructured titanium, and compare their effect with factorymade products currently applied in maxillofacial surgery.Material and methods.The study involved 50 sexually mature male Chinchilla rabbits. An open fracture of the lower jaw was simulated in the animals. In the 1st series of the experiment, the fragments were fixed using nanostructured miniplates and miniscrews made of Grade 4 titanium. In the 2nd series, they were fixed with standard miniplates and miniscrews from Konmet LLC. The material for the study was taken on the 7th, 14th, 21st, 28th and 40th days after the operation. In all series the object of the study was the extirpated lower jaw in the fracture area. The prepared histological sections were stained with Mayer's hematoxylin and eosin. The immunohistochemistry technique was used to identify cells with signs of proliferation (synthesizing the Ki67 protein), to assess the expression of the synthesis of proteins p53, caspasa 3 and the anti-apoptotic protein bcl-2. The surfaces of titanium structures were studied by scanning electron microscopy. The results were processed statistically.Results.The study investigated the effect of miniplates and miniscrews made of nanostructured and standard titanium on rabbits. The data obtained revealed the nature of the proliferative and apoptotic potentials of osteoblasts in the regenerate, and also indicated an increase in the ratio of the number of cambial cells and cells with an apoptotic dominant in the zone contacting with the nanostructured surface of the titanium screw compared to the titanium screw manufactured by Konmet LLC. Taken together, the obtained data indicate that the use of nanostructured titanium Grade 4 for the production of miniplates and miniscrews has an optimizing effect on reparative osteogenesis. The mechanism of this effect is determined by the presence of osseointegration properties of titanium.Conclusion.Nanostructured titanium is advisable to use for the production of implants, reconstructive titanium plates and other products for bone grafting.

Partial discharge (PD) detection is vital for evaluating the health of power cable insulation, where failure can lead to significant disruptions. This study investigates the use of Ultra-High Frequency (UHF) sensors to detect PD signals, which typically occur in nanoseconds. The sensors operate in the GHz range and minimize interference by selecting frequencies above 400 MHz, where background noise is reduced. Through comparison with other detection methods, UHF sensors demonstrate superior sensitivity in measuring minor discharges, providing a reliable means for on-site condition assessment of high-voltage equipment. The study concludes that UHF sensors offer a practical solution for improving PD detection accuracy, particularly in challenging field conditions.

Authors: Sharma Manju
Published: September 2024

Cyberbullying has been identified as a biggest problem for the last decade. In this paper we will discuss some recent findings and focus on general concepts within the area. This paper covers issues like repetition and power imbalance, types of cyberbullying, age, cyberbullying and traditional bullying, motives for and impact of cyber victimization, coping strategies, and prevention/intervention possibilities. Understanding the characteristics and methods of typical cybercrimes can help us better arm ourselves with the information and resources needed to reduce risks, improve cyber-security, and protect our online identities. However, hackers, phishing fraudsters, and other cybercriminals seized the chance to profit greatly from this chaos. Phishing assaults and cybercrime complaints have skyrocketed throughout the epidemic, putting a great deal of people & small organizations at danger of identity theft, credit card fraud, or data breaches.

Authors: Paras Negi  , Manoj Kumar Bisht
Published: September 2024

Machine learning is a type of artificial intelligence that allows applications to become more accurate at predicting results without being explicitly programmed to do so. Machine learning techniques such as Decision tree, K-Nearest Neighbors (KNN), Naïve Bayes, Support Vector Machine (SVM), Logistic Regression, Multi layer perceptron etc, are used to predict the heart attack. These studies offers an analysis of the existing machine learning algorithm and provides a comprehensive overview of the previous research and evaluate the accuracy of the machine learning modals. Both low and high-risk patients for a heat attack were evaluated for the study. The results indicate that methods Logistic Regression and Support Vector Machine algorithms outperform other traditional classifiers in terms of prediction accuracy and generalization.

Aim: Studies on obese individuals have proposed a correlation between weight loss and variations in mean platelet volume (MPV). Therefore, this study aimed to examine the changes in MPV in morbidly obese patients who underwent weight loss via bariatric surgery.
Material and Methods: A total of 328 morbidly obese patients who underwent sleeve gastrectomy (morbidly obese group) and were retrospectively evaluated from January 2010 to November 2014. The control group consisted of 53 non-obese patients who had laparoscopic cholecystectomy. Body mass index values and MPV values at preoperative (baseline), postoperative 1st month, 3rd month, and 12th month for both groups were documented.
Results: The baseline MPV values were comparable between morbidly obese group and control group (8.8 ± 1.8 vs. 8.6 ± 1.2, p = 0.283). In control group, there was no significant change in MPV levels during the 12-month follow-up. In morbidly obese group, mean MPV levels at the 1st and 3rd months post-surgery were similar, showing an increase compared to baseline levels. By the 12th month, mean MPV levels tended to decrease, becoming comparable to baseline values.
Conclusion: MPV levels increased in the early postoperative period following sleeve gastrectomy, they returned to baseline by the 12th month. These findings suggest that weight loss from bariatric surgery may influence MPV levels, but this effect normalizes over time.

The Innovativeness of the Economies of European Union Candidate Countries – an Assessment of Their Innovation Gap in Relation to the EU Average
Authors: Dworak Edyta
Published: September 2024

Innovation is nowadays seen as an essential success factor in achieving economic prosperity and competing in markets. It is one of the most important determinants of the competitive process throughout the world, helping economies catch up with developing and changing technologies while revealing those countries’ innovation perspectives.
The article assesses the innovativeness of the economies of selected European Union (EU) candidate countries based on the Summary Innovation Index (SII). It also estimates the innovation gap between these countries and the EU average of the SII between 2015 and 2022. The analysis is limited to Türkiye, Serbia, Albania, Montenegro, North Macedonia, Bosnia and Herzegovina, and Ukraine due to the availability of data that describes the SII. It provided for all the countries surveyed in the European Innovation Scoreboards, i.e., the reports of the European Commission, only from 2015. The presented analysis is based on a research hypothesis that suggests that the surveyed countries are characterized by a lower level of innovativeness of economies than the EU average, and therefore, they show an innovation gap compared to the average for EU countries in the analyzed period. The results of the analysis confirm this hypothesis – between 2015 and 2022, the economies of all the examined candidate countries recorded a lower level of innovativeness than the EU average. They showed a lower level of the SII than the EU average, and therefore, all these countries demonstrated an innovation gap compared to the EU average. Recommendations for increasing the innovativeness of those economies are formulated separately in the conclusions.
The article reviews the literature on the innovation and innovativeness of economies and the innovation gap. Descriptive analysis, statistical data analysis, and comparative analysis methods are applied, and statistical data from the European Innovation Scoreboard 2022 are used. The value added of the article lies in its comparison of the level of innovativeness of the economies of selected EU candidate countries to the EU average, as well as its estimation of the innovation gap between these countries and the EU average.
Consumer and Professional Inflation Expectations – Properties and Mutual Dependencies
Authors: Rutkowska Aleksandra , Szyszko Magdalena , Próchniak Mariusz
Published: September 2024

Inflation expectations are a crucial variable for central banks. However, empirically examining their properties is challenging. This paper juxtaposes the properties of consumer and professional expectations. It also assesses the degree of forward- and backward-lookingness and the information content of expectations. We apply entropy-based measures (common information and mutual common information) to capture nonlinear dependencies and dynamic time warping to account for different lags in the relationships. The study covers 12 inflation-targeting economies from the European region. The results suggest that in most countries, professionals are more forward-looking, and consumers follow professionals. Both groups of economic agents present expectations that are aligned in terms of information content. However, cross-country differences occur. These results imply that, from the central bank’s point of view, communication and practices designed to shape expectations, even if understood mostly by specialists, are effective also for consumers. The novelty of this study lies in its use of alternative methods to tackle the formation and dependencies between heterogeneous expectations. This avoids the drawbacks of a standard approach and allows broader conclusions to be drawn.
Exploring ESG Disclosure: What? And Why? A Study of Leading European Public Hospitals
Authors: Wójtowicz Katarzyna , Wójtowicz Jan
Published: September 2024

The purpose of the article. This article aims to examine the sustainability disclosure practices of public hospitals within the European Union. It aims to identify the scope and trends in environmental, social and governance (ESG) information reported by these hospitals on their official websites and analyze the influence of national frameworks on these practices.
Methodology. The study employs a manual content analysis of the official websites of 50 public hospitals from EU Member States, selected from Newsweek’s The World’s Best Hospitals 2024 list. An ESG Disclosure Index (ESG DI) was developed to evaluate the extent of sustainability information disclosed. The index includes 36 items across various sustainability dimensions.
Results of the research. The results show that the surveyed hospitals disclosed an average of 48% of the ESG metrics. Governance issues were disclosed the most (59%), followed by social (52%) and environmental (47%) dimensions. Scandinavian hospitals had a higher level of disclosure than their Southern European counterparts. The study highlights the fragmented nature of sustainability disclosure, which tends to report better performing indicators while selectively omitting others.
