Published: October 2024

The rapid growth of AI-generated images, especially with techniques such as Generative Adversarial Networks (GANs), has complicated the ability to tell apart genuine content from artificial creations. This issue is vital for preserving the authenticity of visual media, where conventional detection methods often struggle. Current detection approaches concentrate on machine learning and deep learning techniques, including neural networks (CNNs). These methods aim to reveal subtle flaws and irregularities in images, like inconsistencies in pixel distribution and lighting, which serve as critical signs of AI involvement. The research emphasizes the necessity for ongoing development in detection technologies to keep up with the quick progress of AI advancements. Ensuring that these detection methods are accurate and dependable is crucial for protecting against misinformation and maintaining confidence in digital content.

Introduction. The study of nanoparticles for potential cardiotoxic effects is a comprehensive multi-stage process based on an integrated approach. Along with generally accepted research methods, molecular biology techniques using modern highly sensitive equipment are being actively introduced into toxicology testing.
The aim of the study was to describe a novel approach to assessing cardiotoxic effects of nanoparticles, from the molecular level to the functional response of the whole organism.
Materials and methods. Our new approach to assessing cardiotoxic effects of nanoparticles in rats included the examination of changes at the molecular (e.g., the ratio of myosin heavy chains), subcellular (by electron microscopy), cellular and tissue (by histological testing), system and organ (by non-invasive recording of electrocardiogram and blood pressure parameters and biochemical testing of blood serum) levels. We have tested the proposed approach by evaluating lead (PBO) and cadmium oxide (CdO) nanoparticles in rats.
Results. Hypotension observed after PbO and/or CdO nanoparticle exposure indicates to the damage to the vascular bed due to penetration and accumulation of the nanoparticles in vascular cells, as well as direct damage to the endothelium, increased oxidative stress, and inflammation. In accordance with the system for assessing nanoparticle-induced cardiotoxicity developed on the basis of toxicology test results, lead and cadmium oxides, both separately and combined, have a pronounced cardiotoxic effect.
Limitations. Our work was limited to examining the main indicators of the cardiotoxic effects of nanoparticles in a toxicological experiment on one animal species (rats).
Conclusion. The data analysis revealed varying degrees of manifestation of nanoparticle cardiotoxicity, both at the molecular level and at the intracellular, cellular, tissue, organ, and body levels. The use of this approach will allow a better in-depth assessing effects of nano-sized particles on the heart and blood vessels for identification of risks for cardiovascular disease.

Authors: Sosedova Larisa M. , Vokina Vera A. , Rukavishnikov Viktor S.
Published: October 2024

Introduction. Long-term smoke from landscape fires causes various health problems, primarily affecting the respiratory, cardiovascular, and nervous systems.
To substantiate safe levels of exposure to smoke from landscape fires, it is necessary to create an adequate biological model for smoke that is close to natural conditions.
The aim of the study is to develop and test methodological approaches to creating a biological model for smoke during landscape fires to substantiate safe levels of exposure.
Materials and methods. Using the developed biological model, we studied the effects of smoke from landscape fires on white rats. We assessed the functional state of the central nervous system based on rat behaviour and EEG examination results, conducted a morphological study of the cerebral cortex and testes of white rats, and examined the offspring immediately after birth and at puberty.
Results. We studied the biological response of white rats exposed to inhalation smoke from landscape fires for different durations. The main criterion indicators of health disorders in the central nervous and reproductive systems of animals were identified.
Limitations. The study is limited by the lack of data on safe levels of exposure to smoke from landscape fires on the central nervous system and reproductive toxicity.
Conclusion. Testing of the developed method allowed identifying the exposure load of carbon monoxide and ultrafine particles PM2.5, at which changes in the nervous and reproductive systems are minimal. A method for calculating safe levels of exposure for the central nervous and reproductive systems, as well as for the effect on offspring, is proposed. An algorithm for conducting research in studying the effect of smoke from landscape fires on the body has been developed.

Authors: Fedorova Natalia E. , Dobreva Natalia I. , Kozak Daria K. , Ivanov Aleksandr A. , Sobolev Dmitriy N. , Panchenko Mihail N.
Published: October 2024

Introduction. Trifluralin is a systemic herbicide of the chemical class of dinitroaniline derivatives. During monitoring studies, trifluralin was detected in carrots produced in the Russian Federation. Since trifluralin-based pesticides are not approved for the use in the Russian Federation, residual amounts of the substance are not typical for this crop. To check the contamination of carrots with a pesticide not typical for this crop, confirmatory qualitative and quantitative studies were carried out.
Purpose of the work. Increasing the efficiency of identification and reliability of quantitative results when monitoring food products for safety when performing confirmatory analytical studies using the example of determining trifluralin in carrots to assess the safety of food products intended for the consumer.
Materials and methods. Gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) was used to identify and quantify trifluralin. Samples were prepared for analysis using the QuEChERS method. Identification was carried out by multiple reaction monitoring (MRM) using a triple quadrupole mass spectrometer using two to four MRM transitions (m/z): 306,1→264,0; 264,0→206,0; 264,0→188,0; 264,0→160,1. Matrix-matched calibration was used for quantitation.
Results. The effectiveness of screening studies when monitoring food products using the GC-MS/MS method can be significantly elevated by increasing the number of MRM transitions (at least 3), controlling the reference retention time of the substance, and maintaining the ratio of confirmatory ions. To obtain a reliable quantification of trifluralin content in carrots, the use of a matrix-matched calibration is recommended.
Limitation. In the study, only carrots were considered as food products.
Conclusion. Confirmation of test results is especially important when determining pesticide residues that are not normally found in a given matrix, or when it is suspected that the maximum permissible level may be exceeded. When conducting a screening study and detecting a food contaminant, contamination of the product can only be reported in advance. Next, a confirmatory analysis is required using a validated quantitative method, including an appropriate calibration procedure. In quantitative analysis, the presence of matrix sample components can cause problems due to sample suppression/enhancement phenomena. Matrix-aware calibration has been shown to be effective in compensating for matrix effects.

Introduction. According to the results of medical examinations of metallurgists, in the structure of newly identified somatic morbidity, circulatory system diseases (CSD) are one of the leading pathologies. To assess the prevalence of CSD in workers in harmful working conditions, it is possible to use various mathematical solutions as a tool.
The objective of the study was to substantiate the possibility of using variance analysis and classification tree (CT) methods to assess the prevalence of circulatory diseases in industrial workers.
Materials and methods. Data of medical examinations and a questionnaire-based survey of three hundred eight workers of steel production were input into a database. The interrelationship between CSD and individual and occupational risk factors was examined using a one- and two-way ANOVA. The classification tree method was used for a multivariate analysis.
Results. The one- and two-way ANOVA revealed a statistically significant correlation between the CSD family history (p=0.001) and age, years of occupational exposure, overweight, blood glucose level, total cholesterol (p<0.05) and the CSD prevalence in the steel workers. We applied the classification tree method to make decisions on referring the subjects to potentially “healthy” and “sick” workers by determining the CSD prevalence in relation to various combinations of risk factors.
Limitations. This study is limited to the results of medical examinations of the workers collected over a one-year period.
Conclusions. Our experience in using the analysis of variance and classification tree to evaluate the CSD prevalence in ferrous industry employees allows recommending them for use in assessing the prevalence of various diseases in workers exposed to occupational hazards.
Bioelectric brain activity in workers with hand-arm vibration in dynamics
Authors: Kuleshova Marina V. , Pankov Vladimir A. , Katamanova Elena V. , Kuptsova Natalya G.
Published: October 2024

Introduction. A few neurophysiologic studies have shown that changes of the bioelectrical brain activity are observed in hand-arm vibration syndrome (HAVS) patients. There is practically no information about the state of bioelectrical brain activity in the hand-arm vibration.
The purpose is to study the dynamics of the formation of neurophysiologic changes in workers exposed to hand-arm vibration.
Materials and methods. Electroencephalography (EEG) and registration of evoked potentials (EP) was carried out in workers exposed to hand-arm vibration (practically healthy workers, HAVS individuals who continue to work in their occupation), twice in a connected sample. The results are presented as median, upper and lower quartiles, and extensive indicators. The significance of differences was assessed using Pearson’s χ2 test, Fisher’s angular transformation, and Wilcoxon T-test.
Results. In dynamics, there is a change in the EEG pattern from disorganized with a predominance of alpha activity to disorganized with a predominance of delta, and theta activity; a decrease in the spectral power of the main EEG rhythms in all main functional leads in both examined groups. Diffuse changes in the EEG indicate a multisystem nature of bioelectrical brain activity disorders with involvement of the cerebral cortex, stem, and diencephalic structures of the brain. Changes in the amplitude-temporal parameters of EP manifested by an excess of the latency of the main peaks and a decrease in amplitude, indicate an imbalance in the central nervous system, general modulating influences on the cerebral cortex of the thalamocortical systems of the brain.
Limitations. One occupational group with different levels of health status – practically healthy workers, HAVS individuals who continue to work in their occupation – was enrolled in the study.
Conclusion. The one-direction and progressive development of changes in the bioelectrical brain activity has been established, manifested by a restructuring of the electrical activity of the brain, desynchronization of neuronal activity, an increase in the level of functional activity of the brain, and an imbalance of general modulating influences on the cerebral cortex. The identified changes are a manifestation of the nonspecific part of the pathogenesis of HAVS.
Ethnic Peculiarities and Inter-ethnic Parallels in the Traditional Material Culture of the Hungarians of Ugocsa
Authors: Kész Barnabás
Published: October 2024

The Hungarians living in the present-day Transcarpathian region have lived peacefully for centuries together with the majority Ruthenian/Ukrainian population, as well as with the Romanian, German, Roma and other ethnic groups, who live in a similar minority to the Hungarians. Ethnographers and tourists visiting the region are convinced that these nationalities have retained the characteristics of their culture to this day. At the same time, it is worth observing how this long historical coexistence is reflected in the way of life and mentality of these people. The parallels between Ruthenian and Hungarian language and folklore, folk customs are excellent examples of interethnic relations, but I have also encountered similar examples when researching the traditional material culture of the villages in Ugocsa. In the field of folk architecture, for example, the gate called tőkés kapu, as well as the abora, aszaló [the dryer] and the barn. Interethnic phenomena between Hungarians, Ruthenians and other nationalities of the region can also be observed in folk costumes (the guba, or the shoes called bochkor). Throughout history, in Transcarpathia, which belonged to different state formations, it was noticeable that culture was not strictly tied to peoples. Thanks to the tolerance shown towards each other, the nationalities of the region have preserved their ethnic and religious characteristics and identity, but we can also find many similarities in their cultures. When studying the interactions that mutually enrich each other's culture and provide a colorful and attractive image to the region, it is often impossible to find out who borrowed from whom and when. During the ethnographic research of the local communities, the main point is to take into account the ethnic interaction of the nationalities living here, as the folk culture of the local Hungarians is determined by the aggregation of the cultures of different ethnicities.

Among several authentication problems, preventing social engineering attacks using behavioural biometric approach has not received the required attention especially with focus on keystroke dynamics. This study aims to leverage the power of deep learning for more accurate and robust continuous authentication based on typing patterns. The proposed framework for this study utilized deep learning algorithm for behavioural biometrics authentication using Keystroke dynamics. The deep learning model was developed using Recurrent Neural Network (RNN) algorithm and was optimized was to obtain a better performance with Bayesian optimization which, eventually enhanced the model's accuracy. The dataset was split into training and testing in the model design phase and some hyperparameters such as dense, activation, batch size, sigmoid, filament, input size and epoch were used and optimized for building the deep learning algorithm. The RNN model is used to generate the evaluation metrics such as log loss, accuracy, precision and recall. The result presented the accuracy, precision, recall, and loss function as 100%, 100%, 100%, and 36% respectively for optimized model. The cost metrics yielded 0.0032, 0.0032, and 0.0006 MAE, MSE, and RMSE respectively. The developed KBB shows high level of social engineering attacks mitigation in comparison with the existing solution from the performance measure results.
Economics of Education: Examining from Different Perspectives
Authors: Oltulular Sabiha
Published: October 2024

To ensure sustainable economic growth and development, human capital is an essential factor of production that should be addressed at least as much as physical capital. Human capital is essential for better regulation, planning, and implementation of physical capital. Economic growth and development are the cause as well as the result of education. As the quality of education increases, economic growth will increase, and the effect of increasing economic growth will be reflected in the education sector. These two values not only positively influence each other, but also feed each other. In this study, which started with the definition and importance of education and education economics, the research continued by explaining the economics of education in detail through various items. It is aimed to examine the economics of education, the historical dimension of education economics, education supply-demand, education in the labor market, and essential education indicators using country data. Human capital is necessary for realizing sustainable growth and development in the long term, and to ensure this process is effective, human capital training can only be achieved through education. It is necessary to invest in quality education. These investments return by increasing the country’s social and economic welfare in the long run. It was observed that education investments in OECD countries and Turkey have increased significantly in recent years. Education should be increased both quantitatively and qualitatively. More effective and efficient educational policies should be determined and implemented without compromisese.

This study addresses the ongoing challenge of maintaining student engagement and motivation in English language learning, particularly among primary school students. With traditional methods proving less effective in sustaining interest, this study aims to explore the impact of gamification on improving students’ engagement and language acquisition. Specifically, the research investigates how the integration of a giant Snake and Ladder game, focusing on vocabulary and grammar, influences students’ learning experiences. The study was conducted with 103 standard six students from a primary school in northern region, Malaysia who played the game in groups and completed a post-game survey. The survey included nine items that assessed the students’ experience and motivation, using a 3-point Likert scale (Disagree, Neutral, Agree). Descriptive statistics, including percentages, mean, and standard deviation, were used to analyse the data. The findings revealed that the majority of students reported enhanced motivation and a better understanding of English, with 76% agreeing that moving around as a token made the game more fun, and 67% stating they learned many new things. The study supports the notion that gamification, particularly through physical activities, can effectively foster engagement and improve language learning outcomes. The implications suggest that educators can integrate similar game-based approaches to enhance motivation and comprehension, especially in language subjects. However, future research should consider larger sample sizes and assess the long-term effects of gamified learning on language retention.
Electoral Conflicts in Cameroon: Causes, Consequences and Remedies
Authors: Njume Ndille Ndille
Published: October 2024

The advent of multiparty politics in Cameroon in the 1990s meant the acquisition of state power was to be achieved through competition, this saw the creation of political parties, birthing a pluralist democracy and shifting the paradigm of partisan politics from the one-party system to a multiparty dynamic. Elections were thus the only means through which these parties had to compete for state power, although it instilled hope in many, this phenomenon was accompanied by much more worrying issues in the name of electoral conflicts. From 1990 till present, elections in Cameroon have always been marred by conflicts. This paper examines the causes and impact of these conflicts on Cameroonians and proposes remedies to optimise the electoral landscape.

Synthesis of Nodupetide Analogue: Substitution of β- to α-hydroxy Acid
Authors: Farah Harra Ismi , Supratman Unang , Hidayat Ace Tatang , Maharani Rani
Published: October 2024

Nodupetide, a cyclodepsipeptide with the potential as an antimicrobial agent, was isolated from the fermentation of the fungi Nodulisporium sp strain IFB-A163. It possessed antibacterial activity against Pseudomonas aeruginosa and revealed an insecticidal activity. In our effort to synthesized nodupeptide, the preparation of the (3S,4S)-3-hydroxy-4-methylhexanoic acid (HMHA) as one of the nodupetide residue was found to be challenging, where it is not commercially available and the synthetic trial of the HMHA was not successful. This led us to synthesize nodupetide derivative by replacing HMHA with its a-hydroxy acid to give the analogue [(2S,3S)-Hmp]2-nodupetide. A combination of solid- and solution-phase peptide synthesis was applied in the synthesis nodupetide analogue. Esterification on the resin for synthesis [(2S,3S)-Hmp]2-nodupetide was achieved by placing the reaction at the last stage of the linear peptide synthesis and obtained in overall yield of 4.3 %. We also conducted antimicrobial activity screening for [(2S,3S)-Hmp]2-nodupetide and its linear precursor, showing inactive activity. The alter of hydrophobicity on the nodupetide analogue has very important role in the difference of bioactivity compared to their parent compound.
HIGHLIGHTS

The synthesized analogue compound has not been reported previously
we studied the synthesis strategy of cyclodepsipeptide.
We studied the change of beta hydroxy carboxylic acid residue to alpha hydroxy carboxylic acid, which has a very significant effect on biological activity.

Authors: Duengo Suleman , Hidayat Ace Tatang , Musa Weny J. A. , Maharani Rani
Published: October 2024

Anticancer peptides (ACPs) is a potential alternative for future cancer therapy. ACPs specifically inhibit cancer cells through a non-enzymatic membranolysis mechanism. One potential anticancer peptide worthy of investigation is BZR-cotoxin IV. Currently, research on BZR-cotoxin IV is limited to isolation, making it an interesting area for further development. One approach to developing BZR-cotoxin IV is through chemical synthesis techniques. This compound belongs to the group of cyclodepsipeptides that are naturally produced by the fungus Bipolaris zeicola Race 3. The synthesis of BZR cotoxin IV involves 3 steps: (1) Synthesis of the hydroxy acid precursor by conversion of L-valine amino acid to (2R)-hydroxyisovaleric acid, (2) synthesis of the linear depsipeptide using solid-phase peptide synthesis on 2-chlorotrityl chloride resin and (3) cyclization of the linear depsipeptide using solution phase synthesis to produce the BZR cotoxin IV compound with a purity of 11.7 %. BZR-cotoxin IV was characterized using HR-TOF-MS and 1H and 13C-NMR to validate the desired product. Anticancer activity testing was performed using the Resazurin assay on the HeLa cancer cell line, resulting in an IC50 of 187.50 μg/mL (214.014 μM) categorized as moderate.
HIGHLIGHTS

The chemical synthesis of BZR-cotoxin IV compounds has not been firstly reported.
The synthesis of BZR-cotoxin IV was accomplished through a combination of solid-phase and solution-phase peptide synthesis.

This study focused on synthesizing fatty acid ethyl esters (FAEE) from Krabok (Irvingia malayana) seed oil via transesterification for use as the primary ingredient in herbal massage oil production. Optimal conditions included 5 wt.% of KOH catalyst compared to the oil weight, 15:1 molar ratio of ethanol to Krabok seed oil, 60 min for reaction time and reaction temperature of 78 ± 3 °C, resulting in FAEE yields as high as 99.83 ± 0.17 %. Analysis using FT-IR, 1H and 13C-NMR, and GC techniques revealed FAEE as ester-type compounds, primarily comprising lauric acid (C12:0) and myristic acid (C14:0), constituting 97 wt.% saturated fatty acids and 3 wt.% unsaturated fatty acids. Physicochemical properties indicated clear yellow liquids with viscosity of 1.73 ± 0.03 cSt/s, density of 0.8199 ± 0.0049 g/cm3, cloud point of +4 °C, and pour point of –1 °C. Acid value, free fatty acid content, iodine value, water content and oxidation stability were measured at 0.703 ± 0.001 mg KOH/g of oil, 0.354 ± 0.001 wt.%, 0.59 ± 0.04 g I2/100 g of oil, 1482.3 ± 6.15 ppm, and greater than 12 h, respectively. When the synthesized FAEE was used to produce herbal massage oil products, the results showed that the herbal massage oil products were characterized as a clear yellow liquid with no sediment, low viscosity, and pH in the range of 5 - 6, meeting standard criteria. Thus, FAEE derived from Krabok seed oil is suitable as a primary ingredient for herbal massage oil production, enhancing the value of local resources within the community.

Accepting Gender
Authors: Stitt Alex
Published: October 2024

Sometimes it is difficult to identify and express our genuine gender identity. When we don't fit the ideal, the gender role, or the social script, we can feel trapped in ourselves. This “stuck” feeling is often reinforced by intrusive thoughts, mental rigidity, and self-judgement. Where do you even begin?

Non-binary counselor, Alex Stitt, lays the foundations for addressing these feelings with reflective exercises and activities rooted in acceptance and commitment therapy (ACT) that help you understand what gender is, the spectrum of different gender identities, how to identify and accept your gender, coming out, self-actualization and much more.

This interactive and humanizing workbook will help you identify your values so you can accept and embody what’s most important to you in your gender exploration.
The Educator’s Experience of Pathological Demand Avoidance
Authors: Kerbey Laura
Published: October 2024

I realised EVERYTHING I was doing was wrong.

I needed to learn.

I needed to change.

During Laura Kerbey's time teaching autistic children, she had a sudden realisation that those with Pathological Demand Avoidance (PDA) are children like no other! None of her tried and tested autism strategies would work to help them focus or learn and most of her time was spent wondering, what am I doing wrong?

If you feel the same, this short, easy-to-read guide is here to teach you everything you need to know from one educator to another. With an introduction to what PDA is followed by PDA tailored advice on how to connect with your student and create an autonomous, spontaneous environment that is personalised for you both, this guide is here to ensure that you and your PDA student thrive!

Illustrated by the popular Eliza Fricker and packed with entertaining anecdotes (including one about Jabba the Hut's poo), this go-to-guide contains everything you need to start implementing PDA friendly learning to help you connect with your student and help them make the most of their learning experience.

Teknoloji ve Tasarım Dersinde Harmanlanmış Öğrenmenin Öğrencilerin Tutum, Öz Düzenleme, Bilimsel Yaratıcılık ve Akademik Başarılarına Etkisi
Authors: Sağlık Mehmet Aydın , Özaydınlık Kevser
Published: October 2024

Bu araştırmanın amacı, Teknoloji ve Tasarım (TT) dersinde proje tabanlı öğrenmeye dayalı olarak geliştirilmiş harmanlanmış öğrenme ortamının öğrencilerin; derse yönelik tutumlarına, öz düzenleme becerilerine, bilimsel yaratıcılıklarına ve akademik başarılarına etkilerini araştırmak ve bu ortama yönelik öğrenci görüşlerini belirlemektir. Araştırmada model olarak karma araştırma yaklaşımlarından iç içe karma desen seçilmiştir. Çalışma grubu, 2021-2022 eğitim öğretim yılında öğrenim gören 40 yedinci sınıf öğrencisidir. Nicel verileri toplamak için; “TT Dersi Tutum Ölçeği”, “Algılanan Öz Düzenleme Ölçeği”, “Bilimsel Yaratıcılık Ölçeği” ve “Başarı Testi” kullanılmıştır. Nitel veriler, öğrenci günlükleri ve yarı yapılandırılmış görüşme formuyla toplanmıştır. Nicel veriler SPSS 22 ile analiz edilmiştir. Nitel verilerin analizinde içerik analizi yapılmıştır.
PTÖ destekli HÖ etkinliklerinin, öğrencilerin TT dersine yönelik tutumları üzerinde istatistiksel olarak anlamlı derecede bir etkisinin olmadığı görülmektedir. Algılanan öz düzenleme becerileri, bilimsel yaratıcılık ve başarı değişkenlerinde ise deney grubu lehine olarak anlamlı bir fark olduğu belirlenmiştir. Öğrencilerin, PTÖ destekli HÖ ortamını eğlenceli, farklı bakış açıları kazandıran, kolay, faydalı, yönlendirici, iş birliğine açık, tek başına öğrenmeyi de destekleyen ve etkili buldukları; olumsuz olarak teknik sorunların ön plana çıktığı tespit edilmiştir.
Bu sonuçlar doğrultusunda gelecek araştırmalara yönelik, harmanlanmış öğrenme ortamlarının farklı öğrenme yöntemleri ile desteklenerek ve diğer derslerde de çalışmalar yapılması; uygulamalara yönelik ise harmanlanmış öğrenme etkinlikleri ile desteklenen içeriklerin oluşturulması getirilen önerilerden bazılarıdır.
