Published: September 2024

The research aims to develop and evaluate a model for Internet of Things (IoT) attack identification utilizing IoT data from the Global Cyber Alliance’s (GCA) Automated IoT Defense Ecosystem (AIDE). In the growing landscape of IoT security, the need for enhanced predictive solutions is vital. Our research leverages an enormous dataset, overall historical data from various IoT devices and network interactions, to develop a model to identify potential security threats. The key to our methodology concerns exploratory data analysis, which is focused on understanding complex patterns and anomalies in IoT data. This step is vital for feature engineering, where we meticulously select and transform data attributes to advance the model’s predictive strength. The data pre-processing stage further improves the dataset, ensuring the model training and testing on high-quality, relevant data. Model development is a composite process in this research. We tried out a few machine-learning algorithms, finally selecting the one that exhibited outstanding performance in preliminary tests. The chosen model endured strict training, with a basis on balancing accuracy and validity to effectively predict IoT attacks in various scenarios. The evaluation of our model is as durable as its development. We utilized a range of metrics, including accuracy, precision, recall, and F1 score, to evaluate the model’s behavior overall. The results show that our model not only attains high accuracy but also maintains a notable level of precision in predicting IoT attacks, which is crucial in minimizing false positives. In conclusion, our research contributes to the enhancement of IoT security by providing a very effective predictive model for IoT attack detection.

Quantitative Analysis of the Subsidence Trough of the Barapukuria Coal Mine, Bangladesh
Authors: Malek Md. Abdul , Ahmed Mushfique , Kabir Sohail
Published: September 2024

Subsidence has been an ever-increasing concern of the Barapukuria coal mine for nearly two decades and has indeed called for quantification to predict the expansion of surface subsidence. The study has been undertaken to address this issue. Earlier studies only dealt with the horizontal expansion of the subsidence trough and were calculated based on a rudimentary rule of thumb. On this basis, about 646 acres of land have been acquired and marked as the Influence zone of the mine. However, the extension of the subsidence trough has moved further beyond the Influenced-zone boundary, severely damaging several houses around the mine . This study empirically measures the spatial extension of the subsidence trough identifying mining-induced cracks and joints in 37 affected houses around the mine that emphasized the modification of the rule of thumbs, particularly the angle of draw. It is revealed that the minimum and maximum limit angles are 42o and 60o respectively, and a distance of 378m to 727m (average 552m) must be considered to mark the influenced-zone boundary of the mine while the mining depth is 420m. To precisely quantify and predict the increasing progression of subsidence trough, it is imperative to determine an angle of draw, spatial and areal expansion, and the geotechnical properties for this specific mine.

Published: September 2024

Several studies have been conducted to identify the potential impact of landfills on groundwater resources. This study evaluates the impact of landfills on groundwater resources in Mohammedia prefecture, Morocco. The groundwater was analysed from 2015 to 2022. The groundwater quality was evaluated based on electrical conductivity, pH, biological oxygen demand, chemical oxygen demand, total Kjeldahl nitrogen, phosphate, suspended solids, dissolved oxygen, ammonia, and total hydrocarbon, aluminium, iron, cadmium, chromium, copper, iron-nickel, zing, and mercury. The assessment was based on the water quality index, leachate pollution index, non-carcinogenic risk assessment, and carcinogenic risk assessment. A leachate pollution index <5 indicates that it poses a severe risk to groundwater resources. The non-carcinogenic risk HQ was determined to be <1, which infers no potential risk. The carcinogenic risk index value of 10-4 indicated that it is within the threshold of acceptable limit. The current study concludes that leachate from the analysed landfills does not infiltrate the groundwater resources of Mohammedia prefecture. However, the leachate pollution, even though it varies, is increasing over time. This is validated by the fact that the landfill is protected with a membrane covering the ground, which inhibits any possible infiltration of soil or water resources. Hence, this study calls for continuous monitoring of groundwater resources in the region. Future studies are required to investigate the groundwater in Mohammedia prefecture in terms of emerging pollutants to identify any potential risk.

Constructing and refining a model of antecedent mechanisms of parental educational anxiety in the context of General and Vocational Segregation: A mixed study based on an exploratory sequential design
Authors: He Zhen , Liang Bingbing , Ye Jian-Hong
Published: September 2024

General and vocational education segregation at the high school level has long been a hot topic in China's education system. To contribute to addressing parental educational anxiety in such a context by enhancing its causal mechanism model, this study utilized an exploratory time-series research design and a mixed research method. Initially, in-depth interviews were conducted, followed by coding analysis. They revealed that parents' educational anxiety is characterized by "insufficient information and elevated anxiety", and its main factors were identified as the parents' level of policy understanding, environmental modeling, family support, and perception of educational fairness. A questionnaire was then created to investigate educational anxiety as a variable, and the results were analyzed using fuzzy set qualitative comparative analysis to conduct a configurational analysis. Parental educational anxiety was categorized into three fundamental modes: the policy-information-driven mode, the information-consumption-driven mode, and the subject-information-driven mode. The results of the analysis indicate that the level of parents' understanding of educational policies influences their educational anxiety level, their orientation on media communication affects their recognition of the educational ecology, and their image of vocational education exacerbates their internal anxiety.

Published: September 2024

Due to the development of higher-education marketization, colleges and universities in China's provinces, cities, and regions are facing fierce competition and significant challenges, and vocational universities are no exception. In order to further enhance their visibility and social recognition, vocational universities have adopted various publicity strategies, especially utilizing social media platforms such as WeChat, Weibo, TikTok, and XiaoHongShu. Using the framework of visual grammar analysis, this paper investigates the identity construction in the discourse of vocational universities on social media by analyzing images posted on social media platforms by 33 vocational universities in China. The research findings show that vocational universities use visual content on social media to construct their identities as being skilled, service-oriented, regional, international, employment practice-oriented higher-education institutions that are equal to those in general higher education. This reflects the value of vocational education in today's Chinese society and the realistic difficulties and development challenges faced by higher-vocational colleges and universities.
A posse comitatus intézményének történeti áttekintése az angol gyökerektôl a Posse Comitatus Actig
Authors: Kelemen Roland
Published: September 2024

A posse comitatus ősi angol intézmény, amely lehetővé tette, hogy a sheriff a tizenöt évesnél idősebb férfiakat felkérje (felhívja) a béke megőrzésére, a törvények betartatására, zavargások leverésére, bűnözők elfogására.
Az intézmény tradíciói szerint a helyi közösséget megilleti annak a joga, hogy a közösség békéjét zavaró egyéneket közös erővel elfogják és bíróság elé állítsák. E jogot használták fel a feudális kor uralkodói arra, hogy rendészeti szervek hiányában a polgárok ezen jogát többször megerősítve a közbiztonságot fenntartsák. A posse comitatus intézménye azonban az évszázadok során más jelentéstartalmakat is felvett, így például a Magna Charta ellenállási záradéka végrehajtásának szükségképpeni alapját jelentette a fegyverviselési jog, illetve az Egyesült Államokban a szökött rabszolgák elfogásának szigorítását biztosította.
Vallási türelem a török hódoltság idején
Authors: Falus Orsolya , Lengyel Zsolt
Published: September 2024

A törökökkel vívott háborúk után a 17. század végére a magyar etnikum kisebbségbe került a Magyar Királyságban. Míg a déli szerbek továbbra is ortodoxok maradtak, az erdélyi románok és a Kárpátok ruszinjai nagy számban csatlakoztak a Habsburgok által favorizált katolikus egyházhoz. A 17. század folyamán a protestáns nemesség jelentős szabadságot nyert Magyarországon. A Habsburg uralkodók újrakatolizáló erőfeszítései miatt azonban ezt a szabadságot fokozatosan korlátozták. Az állami befolyás a katolikus egyház ügyeiben is erős volt, különösen a felvilágosult abszolutista jozefinista (II. József 1780–1790) korszakban, amikor feloszlatták a szerzetesrendeket. A református és az evangélikus vallás a 18. század végén nyerte vissza szabadságát. Abban az időben, bár e vallások szabad gyakorlása megengedett volt, státuszuk messze nem volt egyenlő a katolikus egyházéval. Annak ellenére, hogy az 1848-as forradalmi jogszabályok minden bevett vallás egyenlőségét deklarálták, a zsidó vallás elfogadása csak 1867-ben következett be az 1867. évi XII. tc. hatálybalépésével (izraeliták egyenjogúságáról polgári és politikai jogok tekintetében). Világosnak tűnik, hogy a Habsburg Birodalomban a magyar liberális politikai elit, hasonlóan az osztrák liberálisokhoz, megoldásokat keresett egy sokvallású és multikulturális társadalomban, amely a török hódoltság után jellemezte hazánkat. Ezt a folyamatot árnyalta azonban az uralkodók elkötelezettsége a katolikus egyház mellett.

How Performance Management Enhances Employee Job Performance? “Finding the Silver Lining”
Authors: Parent-Lamarche Annick , Fortin-Bergeron Chloé
Published: September 2024

Purpose of this paper: Employees’ job performance is considered essential to the survival and success of organizations. Building on the Job Demands-Resources (JD-R) model, this multilevel cross-sectional study aimed to examine the direct effects of performance management (PM) on employees’ job performance, as well as the moderating role of PM practices in the relationship between recognition and employees’ job performance and in the relationship between psychological well-being and employees’ job performance.

Design/methodology/approach: Multilevel regression analysis was executed with Stata 16 software. The data were processed according to their hierarchical structure (i.e., 251 employees nested in 18 organizations).

Findings: Although PM do not directly influence employees’ job performance in this study, it interacts with recognition and psychological well-being to accentuate their effects on job performance.

Research limitations/implications: This study is cross-sectional and relies on employees’ self-report questionnaires. PM does not appear to be the cure for all ills, but still seem to be resourceful to employees, showing that every cloud has a silver lining.

Practical implications: Performance management should be considered by HRM professionals and promoted among managers and employees as an organizational tool for orienting and optimizing employees’ resources that contribute to good functioning and goal attainment at work.

Originality/value: These results extend the literature by illustrating that performance management is still useful in organizations when combined with other organizational and individual resources, such as recognition and employees’ psychological well-being. Specific practical implications for HRM professionals are discussed.
Research on China-Laos Cooperation to Combating Cross-Border Telecom Network Fraud
Authors: NAMNOUVONG Souksavanh
Published: September 2024

Telecom network fraud has arisen as a significant transnational crime impacting China and Laos, capitalizing on legal, jurisdictional, and technical discrepancies between the two nations. This paper analyzes the collaborative initiatives between China and Laos to address cross-border telecom network fraud, highlighting significant joint operations carried out from 2016 to 2024. The magnitude of telecom network fraud is shown by the extradition of over 2,500 criminals from Laos to China, which has averted millions of dollars in financial damages via collaborative law enforcement initiatives. The study analyzes significant hurdles, including jurisdictional limitations, technology inadequacies, and political factors that influence the effectiveness of joint operations. This paper proposes improved strategies for real-time digital evidence-sharing, the formation of joint task forces, enhanced financial intelligence monitoring, and expedited extradition processes through the analysis of case studies and ongoing collaborative efforts. By enhancing technological capabilities, offering training, and bolstering political support, China and Laos can establish a more robust framework for addressing telecom network fraud and ensuring regional security.
A New Approach to the Solution of Facility Layout Problems with Filled Function Method
Authors: Sahiner Ahmet , Başağaoğlu Fındık Ayşe , Kocaer Emine Rumeysa , Özdemir Gültekin
Published: September 2024

Facility layout problems are generally solved by stochastic methods in the literature. The large number of iterations used in these methods is quite costly in terms of solution time. In this study, in order to get rid of this disadvantage, the facility layout problem was solved using the filled function method, which is known to be very successful in solving global optimization problems. In order to demonstrate the effectiveness of the filled function method, the classical linear facility layout problem was handled in a non-linear manner and the problem was deliberately made more difficult. In order to use the filled function method, the facility layout problem was transformed into an unconstrained and multimodal (including more than one local minima) global optimization problem by using the hyperbolic smoothing technique and the penalty function method. Thus, in this first study in the literature where a deterministic method is combined with the solution of the facility layout problem, it is shown that the non-convex facility layout problem can be solved with the filled function method with very few iterations and short solution times.

Authors: İmak Andaç
Published: September 2024

In today’s world, the rapid development of photovoltaic (PV) power plants has facilitated sustainable energy production. Maintenance and defect detection play crucial roles in ensuring the continuity of energy production. The manual inspection of electroluminescence (EL) images of PV modules requires significant human power and time investment. This study presents a method for the automatic fault detection of PV cells in EL images using hybrid deep features optimized with a principal component analysis (PCA) feature selection algorithm. A lightweight and high-performance model that combines the strengths of convolutional neural network (CNN) architectures was proposed. First, data augmentation techniques were employed owing to the imbalance between the defective and functional classes in the dataset containing EL images. In experimental studies conducted by integrating the PCA algorithm into MobileNetV2, DenseNet201, and InceptionV3 CNN models, accuracy, precision, recall, and F1-score values of 92.19%, 92%, 90%, and 91%, respectively, were achieved. When the results were analyzed, it was observed that the proposed method was effective in detecting faults in PV panel cells.

La producción de cacao en Ecuador es fundamental tanto económica como culturalmente, pero enfrenta serios problemas debido al hongo Moniliophthora roreri, causante de la moniliasis. Se evaluó la eficacia de los agentes de biocontrol Trichoderma harzianum y Bacillus subtilis para controlar M. roreri en cacao CCN-51. La investigación se realizó en la finca "San Pedro" en Bolívar, utilizando un diseño de bloques completos al azar con cuatro tratamientos y tres repeticiones, totalizando 12 unidades experimentales. Se aplicaron diferentes dosis de biocontrol y un tratamiento convencional a intervalos regulares usando una bomba fumigadora. Los datos de rendimiento y fitopatología se analizaron con ANOVA y la prueba de Tukey, con un error tipo del 5%. Los resultados preliminares no mostraron diferencias significativas en mazorcas enfermas, sanas e incidencia de M. roreri, pero hubo variaciones en peso de mazorcas, rendimiento por hectárea y severidad de la moniliasis. El tratamiento con T. harzianum (T2) mostró menor severidad de la enfermedad. Estos hallazgos ayudarán a los productores a implementar estrategias de manejo más sostenibles, reduciendo el impacto de la moniliasis en la producción de cacao.

La efectividad de la política pública en la cooperación de la universidad ecuatoriana en ciencia y tecnología para el sector de la defensa. Un enfoque metodológico
Authors: Tamayo-Herrera César , Andrade-Pazmiño Luis
Published: September 2024

La presente investigación aborda con agudeza la situación de las políticas públicas en Ecuador destinadas a promover la colaboración entre las universidades y el sector defensivo en el ámbito de ciencia y tecnología (C&T), destacando la notable precariedad en el desarrollo de C&T para defensa en el país. Esta condición ha inducido una preocupante dependencia internacional, exacerbando los costos en defensa y restringiendo la inversión en la producción nacional. El estudio critica la ausencia de políticas enfocadas en investigación y desarrollo (I+D) para tecnologías militares, fundamentales para amplificar las capacidades operativas de las Fuerzas Armadas. Se propone un modelo para evaluar la efectividad de estas políticas, subrayando la urgencia de fomentar una cultura de defensa que aligere la dependencia tecnológica exterior y reduzca costos, robusteciendo la capacidad de respuesta del Estado ante amenazas. Se examinan detalladamente las políticas de I+D+i en defensa, resaltando la necesidad de un sistema de I+D+i que, alineado con el (Plan de Investigación, Desarrollo Tecnológico e Innovación Militar, 2023), aproveche recursos existentes para un desarrollo futuro. La comparación con Brasil y México pone en relieve la estructura organizativa de Ecuador y la colaboración entre gobierno, academia e industria como claves del éxito de la política pública en defensa.

Os polímeros são macromoléculas formadas por monômeros repetidos, podendo ser homopolímeros ou copolímeros, dependendo do tipo de monômeros envolvidos. Esses materiais apresentam diferentes propriedades conforme sua estrutura molecular, que pode ser linear, ramificada ou reticulada. Polímeros naturais de origem animal, conhecidos como biopolímeros, têm atraído interesse por suas características como biodegradabilidade, não toxicidade e viabilidade econômica. Eles podem ser classificados como polissacarídeos, proteínas ou polinucleotídeos, dependendo da unidade de repetição. Exemplos de biopolímeros animais incluem quitina, quitosana, colágeno e gelatina, amplamente utilizados em diversas aplicações industriais, como na farmacêutica, cosmética e biomédica. A escolha do biopolímero adequado para cada aplicação depende de seus critérios físico-químicos. Desta forma, o presente estudo realizou uma análise aprofundada com base na literatura atualizada, destes critérios, bem como o levantamento de diversas aplicações dos biopolímeros de origem animal.
Mineral Signatures in Oued K’sob River (Algeria): Highlighting Geological Variations and Potential Anthropogenic Impacts

This study examines the mineral composition of sediment samples collected from five distinct zones along the Oued K’sob River in Bordj Bou Arreridj, Algeria using scanning electron microscopy (SEM). The analysis revealed intriguing patterns, the Zone 5 emerged as a distinct outlier, exhibiting significantly lower calcium (29.32% vs. 53.25% in Zone 1) and iron (14.94% vs. 6.31% in Zone 1) content compared to other zones, while displaying a higher silicon content (28.82% vs. 25.27% in Zone 1). This suggests a unique geological origin or specific weathering processes shaping the mineral fingerprint of Zone 5. Interestingly, Zones 1, 2, and 3 displayed a relative consistency in silicon content (around 25%, with pairwise comparisons exceeding p > 0.05), suggesting potential similarities in mineral sources or enrichment mechanisms within their watersheds. However, Zone 4 deviated slightly, showing a higher calcium content (64.18% vs. 29.32% in Zone 5) and lower silicon content (17.99% vs. 28.82% in Zone 5), indicating potential differences in its geological makeup or weathering processes. Furthermore, all zones exhibited trace amounts of elements like lead (Pb) and cadmium (Cd) (ranging from 0.76% to 2.16% for Pb and 0.000% to 0.114% for Cd) (Please recheck these values They are very high). This warrants further investigation to understand their potential anthropogenic origins and impact on the river ecosystem. Further investigations incorporating detailed geological surveys, isotopic analyses, and expanded sampling strategies are recommended to gain a more comprehensive understanding of the complex factors shaping the sediment chemistry within the Oued K’sob River system.

The study was intended to mitigate the destructive after-effects of erosion, where runoff water erodes the arable layers through the increased transport of soil particles. The study was conducted in Ain Zerga across 40 plots, covering an area of 405 hectares, during 2023 and 2024, with a focus on the dimensional evaluation of cereal beds. The evaluation mainly focused (a) on the durability of the structure, including the measurement of settlement, which indicates distribution and strength of resistance to climatic hazards, and (b) proportional sustainability and the interbank aspects. The height of benches, at 0.481± 0.086 m, and the length of 82.583 ± 24.203 m were influenced by height differences and the intensity of water flows. The retention of runoff water was influenced by the slope toward the natural spillway. Furthermore, the destructive intensity of the runoff, amplified by the sharp increase in altitude, was confirmed by statistically significant differences in the length, height, and number of cracks between the study sites (p-value = 0.000). The number of cracks per breach at the Gastel site (4.25 units) and Kef Mebdoua (3.917 units) was higher compared to Ain Zerga, Berket Frass, Ouled Mebarek, and Zlassde, where the number ranged from 0.750 to 1.583 units. The statistical significance in the number of cracks (p<0.001) signified that variation in cracks between the locations was due to the topographic steep slopes on site. The non-significant difference in width suggests that the observed differences could be due to the phenomenon of compaction following the annual infiltration of water on the ridges of cereal bench, plus the act of trampling constantly exercised by sheep and cattle herds when passing to the paths. This work proposed in this article is an attempt to structure a chain of impact analysis of risks and vulnerability of intensity via the sustainability of cereal bench carried out in the Tebessa region.

Este artigo apresenta uma investigação sobre as percepções de professores da Educação Básica acerca da integração das Tecnologias Digitais da Informação e Comunicação (TDIC) em suas práticas pedagógicas. A pesquisa parte da constatação de que, embora as TDIC ofereçam grande potencial para a inovação no ensino, sua implementação enfrenta diversos desafios. Objetiva-se: analisar como os professores percebem esses desafios; e identificar os benefícios proporcionados pelas tecnologias digitais no processo de ensino-aprendizagem. A pesquisa utilizou uma abordagem qualitativa, baseada em entrevistas com um grupo de professores, cujas respostas foram analisadas por meio da técnica de análise de conteúdo. Os resultados revelaram que, apesar das dificuldades estruturais e da necessidade de maior suporte institucional, os docentes reconhecem o impacto positivo das TDIC, sobretudo em termos de personalização do ensino, aumento do engajamento dos alunos e desenvolvimento da autonomia. Conclui-se que a efetiva integração das TDIC no contexto educacional depende de políticas públicas mais efetivas e robustas, que garantam a equidade no acesso às tecnologias e proporcionem uma formação docente contínua e contextualizada.
Reviews on the Land Use and Land Cover Changes in Bangkok

Published: September 2024

Remote sensing has been a highly effective and efficient method for spatial and socio-political analyses for several decades. It utilizes satellite images to map land use and land cover (LULC) and detect changes in this regard. One of Southeast Asia’s megacities, Bangkok has undergone significant land use dynamics and related socioeconomic activity changes. Recently, the new Land and Buildings Tax Act B.E. 2562 (A.D. 2019) has been implemented, which could impact land-use changes, particularly in vacant lands. This study aims to review the literature on LULC changes in Bangkok since the implementation of the land tax and to provide a summary of the main findings. The reviews indicate that previous literature on LULC in Bangkok has primarily focused on environmental or spatial factors, rather than socio-economic ones. This highlights a gap in our understanding of the socio-economic and LULC impacts of land taxation.
