Authors: Elizabeth Atieno Otieno
Published: October 2024

Cognitive Radio (CR) technology offers dynamic spectrum access, allowing for more efficient use of the radio frequency spectrum. While this innovation addresses spectrum scarcity, it introduces significant security and privacy concerns. This paper examines key vulnerabilities in cognitive radio networks (CRNs), including spectrum sensing data falsification, primary user emulation attacks, and denial-of-service attacks, which exploit the adaptive and opportunistic nature of CR systems. In addition, privacy challenges arise from the frequent sharing of location, identity, and spectrum usage data. This paper explores existing security frameworks, mitigation strategies, and privacy-preserving techniques, emphasizing the need for robust cryptographic methods, trust management, and real-time intrusion detection systems. The paper concludes by identifying open research areas that need attention to develop secure, resilient CRNs while preserving user privacy.

Published: October 2024

Acinetobacter baumannii (A. baumannii) is an opportunistic bacterium that has emerged in recent decades as a major cause of potentially epidemic nosocomial infections. This bacterium has impressively developed resistance to most antibiotics, which explains the therapeutic challenges encountered. The aim of this study is to determine, through a retrospective analysis, the epidemiological profile and antibiotic resistance of A. baumannii strains isolated from diagnostic samples collected at Avicenne Military Hospital in Marrakech (HMA), and to track their evolution over the past 3 years (2020-2023). During our study, 105 strains of Acinetobacter baumannii were isolated from various samples received in the laboratory, with a male predominance of 74%. The results show that A. baumannii was identified in 48% of cases from bronchoalveolar lavage, 13% from blood cultures, 11% from sputum, 6% from urine cultures, 5% from bronchial aspiration, 8% from venous catheter samples, 4% from pus samples, 3% from protected distal samples, and 2% from biopsies. The isolates exhibited a high level of resistance to tested beta-lactams: 88.57% for piperacillin-tazobactam, 89.52% for imipenem, and 77.14% for ceftazidime. Regarding other classes of antibiotics, 75.23% of strains were resistant to trimethoprim-sulfamethoxazole, 81.9% to amikacin, and 91.42% to ciprofloxacin. These results confirm the multidrug-resistant nature of A. baumannii and its nosocomial character. This resistance poses a serious therapeutic and epidemiological problem, underscoring the need for a microbial environmental monitoring system in the hospital and the strict implementation of preventive measures.

This study was conducted with the aim of describing and explaining in detail the strategic competencies in mathematics possessed by grade VIII students who have mathematical abilities at high, medium and low levels after they learned independently using electronic modules (e-modules). It focused on Kilpatrick's theory of strategic competence, specifically examining students' strategies for formulating, representing, and solving math problems. The qualitative descriptive research involved 3 students from class 8B at Manbaul Ulum Islamic Junior High School - one each with high, medium, and low math ability based on their daily assessment and midterm exam scores. The instruments used were SPLDV (System of Linear Equations) e-modules for self-learning, strategic competence tests, and interview guidelines. The results showed that students with high and medium math abilities fulfilled all strategic competence aspects - formulating problems through reading and verbal approaches, representing problems by making equations and using symbols, and solving problems analytically. However, students with low math abilities could only fulfill the formulating aspect by reading and verbal approaches. They struggled with representing the problem, and as a result could not solve it. In summary, math ability level impacted students' strategic competencies, with higher abilities correlating to stronger skills across all three aspects examined after e-module based self-learning.

De burgués a caballero: efectos de la guerra en La tierra fértil de Paloma Díaz-Mas
Authors: Lacalle Juan Manuel
Published: October 2024

El artículo aborda un episodio central de la novela histórica La tierra fértil (1999) de la autora española Paloma Díaz-Mas. Se trata del vínculo entre Arnau de Bonastre y su vasallo Joan Galba, antecedido y continuado por distintos tipos de enfrentamientos bélicos. Las problemáticas individuales se entrecruzan con las colectivas, lo que servirá de pretexto o justificativo para la guerra. A través de esta representación, la novela ofrece una imagen más bien negativa de la guerra en el siglo XIII, conectada con la construcción de una Edad Media oscura, cruda y realista, y busca evidenciar y concientizar sobre los antecedentes necesarios de un presente de bonanza construído sobre sangre, violencia y exclusión.

Authors:   Korean Society for Educational Evaluation, Na Wooyoul , Kim Kyunghee
Published: October 2024

The purpose of this study is to explore the risk of grade inflation in high school grading system from a data-driven empirical approach. Specifically, a series of indicators for detecting the risk of grade inflation were derived from high school assessment result data including there were related with the grade inflation such as achievement level ratio, GPA, and the cutoff score by achievement levels. Furthermore, data analysis was performed to identify the characteristics of the indicators derived from this study and to comprehend the the assessment results of the high school in terms of the risk for grade inflation. Consequently, approximately one to five percent of the result of the high school assessment during 2022 were classified as “cautionary” with regard to achievement assessment monitoring. These cases were displayed a high A grade level percentage and GPA, coupled with lower cutoff scores for A grade levels in comparison to those of typical high schools. Furthermore, the high school assessments in which an extremely high percentage of A grade level tend to be characterized as very high GPA or very low cutoff scores for A grade. Based on these results, the implications of applying indicators for monitoring achievement assessment were discussed in order to prevent the phenomenon of grade inflation and to reinforce the achievement standard-based assessment system.

Authors:   Korean Society for Educational Evaluation, Kim Minjung , Yi Hyun Sook
Published: October 2024

In this study, we conducted a time-series clustering analysis based on dynamic time warping distance to understand learners’ behaviors observed in an online learning environment. We used log data from an English e-book learning system and compared the characteristics of learners in clusters derived from the analysis. Additionally, we compared the results of our analysis with those of aclustering analysis that did not reflect the time-series information of the log data. The main findings of this study are as follows: First, through a preprocessing process that focuses on the fluctuations in learning behavior observed over continuous time-series, we identified time-series patterns of learning behavior reflecting individual variability: one with high completion rates on weekdays, another with consistently low performance, and a third group exhibiting highly distributed patterns. Second, no significant differences in learning time and performance were found between the consistently low-performing group and the distributed group. Third, by comparing the clustering results with those obtained from the monthly average learning behaviors, the study highlighted the importance of this approach in terms of information retention. Based on these findings, the study discussed the need for alternative methods and methodological implications in processing and analyzing log data, where online learning behaviors are recorded in real-time.

This is a case study that establishes a sample survey design plan for all grades in elementary, middle, and high schools in Korea for the purpose of representing population at the national level. The main purpose is to provide academic and practical implications for survey-based education data collection by reflecting the structure and characteristics of school data. To this end, based on cases of survey design at the national level in Korea and abroad and the results of simulation experiments to secure representativeness of the results by grade for all elementary, middle, and high schools, a two-stage stratified cluster systematic sampling scheme was derived, and a plan for obtaining results at the national level and by grade was presented, and the main issues in the process were discussed.

The article examines the graphic, orthographic and linguistic features of the Varsonofevskaya Kormchaya of the 14th century, which belongs to the Kormchaya Books of the Early Russian version. The manuscript is in the State Historical Museum, Chudovskoye collection No. 4. According to the research of E. V. Ukhanova, it was written by 6 scribes, 3 of whom were responsible for the great part of the text. The spelling of the copy is Old Russian, with characteristic East Slavic features. The manuscript is characterized by a rare method of abbreviating words by letter names. In the spelling of the manuscript, Novgorod dialect features can be traced, which might indicate the potential Novgorod origin of the manuscript itself or, rather, of its protograph.
Integration of Deterministic Seismic inversion with Machine Learning for Reservoir Characterization
Authors: Farfour Mohammed
Published: October 2024

Seismic inversion plays a key role in reservoir characterization. The inversion allows interpreters to transfer data from interface properties to layers and physical properties. Various deterministic approaches are available for interpreters to achieve this objective, including model-based, trace-based, recursive approaches, etc. Machine learning methods are increasingly adopted in reservoir characterization workflows to identify nonlinear and complicated relationships between various parameters, helping to predict one parameter from another or combine one with others. In this study, we employ pre-stack model-based inversion to invert seismic data for P-wave and S-wave impedances. We extract numerous seismic attributes from the seismic data and use them to train a Feedforward Neural Network to predict the computed impedances at well locations. We compare the impedance models from deterministic inversion with those produced by the ANN. The resulting models are validated using wells that were not included in the inversion or ANN training. The ANN demonstrates good capability to reproduce results close to the inversion results. Next, the P-wave and S-wave impedance models are used for a detailed characterization of the fluvial-deltaic reservoir in the study area. Various quantities are derived, including Poisson ratio, Bulk modulus, Shear modulus, Lambda-Rho, and Mu-Rho. All models are combined using another ANN that has been trained to classify the area of interest into reservoir and non-reservoir facies. The trained ANN allows us to delineate potential reservoir facies and identify some new zones that are not drilled. In conclusion, the ANN emerges as a key player in reservoir characterization. The above study's methodology can be applied to other fields. As the proposed workflow is data-driven, better results can be achieved than those in the present study.
Action plan diversity in children during control exploration: Link between action and sense of agency

The sense of agency refers to the subjective feeling of controlling one’s own actions and, through them, external events. It is a crucial aspect of consciousness, indicating that an agent can understand the causal relationship between their actions and environmental changes and, more importantly, voluntarily influence the environment through their actions. There has been extensive debate about when children and which animals possess the sense of agency, primarily because they cannot easily report it. Observing actions might be a promising way to estimate the sense of agency without relying on introspection. However, despite actions containing rich information about human subjective feelings, there are very few ways to abstract such information. In the present study, we aim to clarify the relationship between actions and the sense of agency during control exploration using a dataset of 167 children (6-16 years old) acquired by Nobusako et al. (2022). We employ action plan analysis developed by Chang et al. (2024) to analyze motion sequences data which was self-generated by participants during a control detection task. The action plan analysis uses transformer-LSTM-based autoencoders to capture high-level, abstract representations of sequences of motor commands (referred to as action plans). This approach allows us to quantify action plan diversity that reflects control exploration behaviors. The results showed that action plan diversity can be a promising way to measure the sense of agency both within individuals and among them. This suggests that simply observing how actions change under different control conditions can quantitatively reflect the emergence of the sense of agency in children. The findings and methodology provide a highly novel and useful tool for studying the sense of agency in broader populations and species in future studies.
Truth Wins: True Information is More Persuasive and Shareable than Falsehoods

The English poet John Milton portrayed truth as a powerful warrior capable of defeating falsehood in open combat. The spread of false information online suggests otherwise. Four experiments, involving human participants and Large Language Models (combined N=4607), are reported that compare the persuasive impact and transmission potential of true and false information. The results consistently showed that messages created with the intent of being true were more persuasive and more likely to be shared than those created to be false. While perceived message truth was the primary driver of persuasion, positive emotion and social engagement were the primary drivers of message transmission. Our findings indicate that in the marketplace of ideas, truth wins.
A new method for calculating the food self-sufficiency ratio: Supply-side food self-sufficiency ratio
Authors: Takahashi Goro
Published: October 2024

Background: The conventional formula for calculating food self-sufficiency cannot cover all the food we eat on a daily basis, and the food self-sufficiency ratio (FSSR) of each country cannot be calculated. The conventional food self-sufficiency ratio (CFSSR) can only calculate the FSSRs of each country for grains. To determine the actual state of food insecurity worldwide as accurately as possible, a method for calculating the FSSR of each country for all the foods we eat on a daily basis is needed. To address this situation, this study proposes the supply-side food self-sufficiency ratio (SSFSSR), which can be used to systematically calculate the self-sufficiency ratio of all foods in all countries/regions.Results: We compared the results of both calculations under the same conditions and used the same data to determine whether the CFSSR or the SSFSSR is a more suitable method for obtaining basic information and formulating measures of global food security. The results showed that the SSFSSR has advantages and practicality over the CFSSR. The SSFSSR can calculate self-sufficiency ratios for all foods in all countries/regions of the world, and the figures for various statistical tests are better. The food that is the subject of the calculation in the SSFSSR formula is the entire supply from production, distribution, storage, and consumption, excluding duplication in the calculation, and includes primary products required to produce secondary products, such as livestock products and edible oils. The study also highlighted the value of reducing the amount of primary products used to produce secondary products such as livestock and edible oils, thereby lowering the primary product conversion rate (PPCR).Conclusion: This study used actual data to estimate the SSFSSR for each country/region to demonstrate the applicability of this method and that lowering the PPCR would lead to an increase in the food self-sufficiency ratio. To further refine this methodology, we find that the most important tasks for the future are to collect more reliable data on calories per weight for a large number of foods, expand the number of types covered by more reliable PPCRs, and analyze those data.
Leveraging Multimodal LLMs for Plant Species Identification and Educational Insights

Published: October 2024

In this study, we investigate the potential of multimodal large language models (LLMs) for plant species identification and educational enrichment. Using an annotated dataset focused on fungi, particularly those classified as edible or non-edible, we implement a practical application that allows users to upload plant images. The LLM then identifies the species, determines its edibility, and provides detailed information on its characteristics. For edible species, the model offers culinary insights and preparation methods, while also delivering comprehensive educational content on plant ecology and cultural significance. Our approach showcases the ability of LLMs to bridge image recognition with rich, text-based knowledge, facilitating an interactive learning experience that promotes plant literacy and practical understanding. This study highlights the effectiveness of LLMs in educational tools and their potential to enhance public awareness of plant species, including fungi, through visual and contextual data fusion.
