Analog Spiking Neuron Model for Unsupervised STDP-based learning in Neuromorphic Circuits
Authors: Bossard Yannaël , JOUNI Zalfa , Wang Siqi , Ferreira Pietro M.
Published: January 2025

Neuromorphic computing has emerged as a promising solution to meet the computational demands of artificial intelligence and enhance the energy efficiency through spiking neural networks (SNNs). This paper models a previously published biomimetic electronic neuron (eNeuron), focusing on the effects of its random noise within an analog SNN framework. The analog SNN is trained via Spike-Timing-Dependent Plasticity (STDP) using unsupervised learning method. Its computational efficiency is evaluated against two benchmarks. Preliminary results have demonstrated that the analog SNN with either simplified or omitted random noise modeling perform better than those with full noise modeling. This highlights the significant impact that random noise of transistors in the eNeuron has on STDP learning processes. However, if random noise is neglected during the training phase, the reintroduction of noise modeling in the testing phase causes an average accuracy drop of only 0.2% for the simplified model of random noise and 4.5% for the full model.

Published: January 2025

Recent advancements in video encoding have enabled significant compression rates but at the expense of increased power consumption and computational demands. This trade-off has driven the need for dedicated accelerators capable of leveraging the parallelism inherent in computationally intensive encoding tasks, particularly through customized hardware solutions. In this work, we introduce a hardware accelerator specifically designed for Fractional Motion Estimation (FME), a key component in video encoding. Our approach leverages cross-layer approximate computing to bridge the gap between logic (arithmetic blocks), architecture, and software layers. The proposed architecture, named 4TAxA, employs an interpolation filter that supports various configurations of approximate adders. Synthesis results using ST 65nm technology demonstrate that the 4TAxA filter core achieves power savings of 69.20% to 90.64% and area reductions of 50.13% to 72.59%, compared to a precise implementation with equivalent throughput. Considering a complete FME unit and a fair or better image quality threshold, our method delivers up to 60.8% power savings and 28% area savings. We expect that our contributions help designers by enabling energy- and quality-efficient encoding systems, offering a promising direction for future cross-layer approximate computing strategies.

Published: January 2025

The importance of the availability of children's literature is currently a special concern in society, because children have the right to receive literature that is appropriate to their age and needs. The availability of children's literature in public libraries is an obligation and provides children's literature that is ready to be used to meet children's information needs. This research aims to determine the availability of picture story book collections, types of picture story books and the process of maintaining picture story book collections in the Aceh Library and Archives Service. This research uses qualitative research methods. The research instruments used were observation, interviews and documentation. The subjects in this research were 4 librarians and 4 deposit room staff who were selected using a purposive sampling technique because they could provide in-depth information needed by researchers. The research results show that the availability of picture book collections is not complete enough because the collection does not meet the five indicators of collection availability which are considered complete. The 5 indicators in question are: variety of types of collections, number of collections, update of collections, relevance of collections, and quality of collections. Of the 5 indicators, only 3 indicators are satisfactory, while the other 2 indicators still need improvement. There are 6 types of picture story book collections; classic fairy tales, educational books, stories about animals, adventure stories, friendship stories, family stories, and inspirational stories. The process of maintaining picture story books goes through 2 stages: 1.) Weeding, namely setting aside books that are damaged and unsuitable, then handing them over to the deposit room for follow-up. 2.) Fumigation, namely fumigation of the reading room to maintain the sterility and integrity of the books from pest attacks.

GENERATING AN IMAGE OF THE CITY STRUCTURE WITH THE USE OF MOCK-UPS, 3D MODELS AND ARTIFICIAL INTELLIGENCE ON THE EXAMPLES OF MODELS OF THE STRUCTURE OF SELECTED CITIES OF THE GZM METROPOLIS
Authors: Bradecki Tomasz , Bal Daria , Mól Błażej , Sanigórska Marta
Published: January 2025

Spatial analysis of cities and regions in the field of urban-architectural planning is usually presented in the form of drawings and diagrams. With the development of spatial information and the capabilities of GIS software and the use of database resources, the creation of illustrations of spatial analysis has become more accessible and easier. According to Kevin Lynch’s theory, the image of a city cannot be determined in an automated way, and their identification requires an authorial approach and research. The article presents a series of experiments series, in which an attempt is made to represent the image of the city using mock-ups, 3D models, using augmented reality, as well as artificial intelligence. The authors put forward the thesis that a contemporary, proprietary representation of the city image in the form of models can be an alternative to traditional diagrams representing the basic elements that make up the city image.
Characteristics of Voice Onset Time among Speakers of Jordanian Arabic with Parkinson’s Disease
Authors: Alfwaress Firas S. , Badarneh Muhammad A. , Mousa Rahaf A.
Published: January 2025

Background: The voice onset time (VOT) is an acoustic measure to assess speech neuroregulatory mechanisms. However, the VOT was not measured in individuals of Jordanian Arabic with Parkinson's Disease (PD). Therefore, this research aimed to measure the VOT using a cross-sectional design. Sixteen individuals with PD and 16 healthy controls had their VOT assessed under two treatment conditions (Off and On-medication). The VOT was measured in several phonetic contexts. The results revealed a higher VOT effect among voiceless consonants for the PD in both experimental conditions than controls. Whereas no effects were observed among the voiced consonants between the two groups. In comparison, no differences were observed in the VOT between the voiceless and voiced consonants among the PD group in the Off-medication condition. The administration of the levodopa affected the VOT measure; a significant decrease in VOT among the voiceless and voiced consonants was observed between the Off and On-medication conditions. Additionally, no significant impacts on VOT were found among the PD individuals when comparing front and back consonants, rounded and unrounded vowels, high and low vowels, and among words versus a sentence.  However, the VOT may vary according to the phonetic characteristics of speech and medication status among patients with PD. The VOT is still considered a sensitive acoustic measure to investigate speech production's neuroregulatory mechanisms and levodopa's effect among individuals with PD in Arabic. Notably, these acoustical markers only represent the first step in the objective biological screening of PD from speech signals.
Exploring EFL Learners’ Perceptions on the Use of AI-Powered Conversational Tools to Improve Speaking Fluency: A Case Study at Majmaah University
Authors: Mudawy Ammar Mohammed Ahmed
Published: January 2025

It is widely known that technology, especially artificial intelligence (AI), presents innovative opportunities for improving English language learning skills. However, little is known about the effect of AI-mediated activities on learners' speaking skills. This study, therefore, aims to explore the EFL learners' attitudes and perceptions of the use of AI-powered conversational tools to improve speaking fluency. Forty EFL learners at Majmaah University were randomly assigned to respond to a structured questionnaire to collect quantitative data, followed by an individual semi-structured interview in the qualitative phase. Thematic analysis was employed for qualitative data, while descriptive and inferential statistics through SSPS were used for quantitative data. The findings of the study indicate that EFL learners at Majmaah University have a positive attitude and perceptions toward using AI-powered conversational tools to enhance and promote their speaking fluency. Moreover, EFL learners at Majmaah University agreed that AI-powered conversational tools improved their speaking fluency, and they felt that their pronunciation was enhanced after using these tools. Additionally, the learners reported significant limitations and challenges, including technical difficulties, such as pronunciation recognition and cultural misinterpretations. In addition, most of the EFL learners in the interviews reported that the lack of personalized feedback was a crucial challenge. The study provides valuable insights for language educators and researchers regarding technology-mediated instruction in language classrooms.
Rebellious Facebook Texts: A Photographic and Stylistic Portrayal of Society Through Electronic Imagery by Harith Ma’ad & Manal Hamdi
Authors: Ismail Ismail Abdulwahhab
Published: January 2025

Facebook has become a vibrant platform for sharing short prose and poetry, offering writers a space to express themselves and seek feedback from a broad audience. While many users are content with "likes" on their posts, others yearn for more meaningful engagement and validation of their literary skills, which they often overestimate. Amid this digital cacophony, certain individuals genuinely stand out as poets and writers, leveraging Facebook to reach global audiences. The concise, high-quality nature of their texts resonates with the platform’s fast-paced environment, contrasting with the longer, traditional forms of print media that electronic platforms increasingly overshadow. This study focuses on the rhetorical imagery in the works of Jordanian poet Manal Hamdi and Iraqi poet Harith Ma’ad, whose poetic prose has earned them substantial followings. By delving into the stylistic and rhetorical elements of their writing, the research aims to reveal how their themes and content align with and contribute to current trends in world literature. Central to their works are concepts such as love, rebellion, societal liberation, and the existential experience of loneliness. These themes not only reflect contemporary cultural and social dynamics but also demonstrate how these writers are actively redefining the boundaries of literature in the digital age, merging tradition with modernity.

Published: January 2025

This paper examines grammatical transformations (translation techniques), in rendering the works of Akhmet Baitursynuly into Russian, using a corpus-based approach. The primary analysis is based on the Kazakh-Russian parallel corpus of Baitursynuly’s texts, created by the authors. This corpus serves as a foundational tool for identifying linguistic patterns, translation techniques, and stylistic nuances across the languages. The study focuses on selected texts by Baitursynuly in both Kazakh and Russian. Focusing on selected original texts and their translations, the identified key grammatical transformations include syntactic assimilation, sentence splitting and merging, and grammatical substitutions. These transformations are analyzed to uncover their role in adapting linguistic structures and preserving the stylistic essence of the source material. The study highlights the utility of parallel corpora in translation studies, demonstrating their effectiveness in analyzing linguistic and stylistic nuances. A frequency analysis of specific translation challenges, such as the causative conjunctions sebebі and üjtkenі (both meaning because) in Kazakh, reveals variations in their Russian equivalents influenced by linguistic constraints and Baitursynuly’s stylistic preferences. Corpus-based research methods enable sampling, comparative and contrastive text analysis, and detailed examination of grammatical transformations. The parallel corpus facilitates the alignment of source and target texts, offering quantitative and qualitative insights into the translation process. This approach also provides an empirical framework for examining recurring translation patterns and assessing the influence of language typology on grammatical adaptation. The study utilized exhaustive sampling of linguistic material from original texts and translations, comparative and contrastive text analysis, analysis of grammatical transformations, and text alignment.
Spatial analysis of reforestation sites in the far-north region of Cameroon
Authors: Samuel NTAMACK  , Haroun ALI ADANNOU  , Sylvain AOUDOU DOUA
Published: January 2025

Following the great drought which struck the Sahel countries including the northern part of Cameroon in the mid-1970s, Cameroon, like the other states of the sub-region located on the edge of the Sahara, decided to implement implement drought control activities. This study taking place in the Far North region of Cameroon, generally fits into the field of characterization of natural environments. It aims to structure and highlight the situation of certain reforestation sites in the far north region. Therefore, to achieve the expected results, we used two specific methods of data collection, namely: the in situ method (floristic inventories using the plot method) and the indirect method (downloading of iconographic data on the SOGEFI platforms, COPERNICUS, ATLAS and GEOFABRIK), for remote sensing analysis purposes with a Landsat OLI/TIR image from November 13, 2023 and photogrammetric shots with Pix4. The inventory data and measurements taken in the field were recorded in CSV and/or XLSX formats for the purposes of statistical analyzes (PAST, Excel) or cartographic operations (Qgis versions 3.22 and 2.18). To this end, the field surveys collected in situ made it possible to carry out thematic mapping using the inverse distance interpolation (IDW) method. The processing of remote sensing data consisted of assembling satellite images using “mosaicking”, radiometric and geometric corrections, and spatial filtering using ENVI and SAGA Gis software. The analysis of these images consisted of calculating vegetation indices (the NDVI adjusted to the ground). It thus appears that the reforestation sites have a deciduous population, a natural habitat composed of shrub savannah, tree savannah, grassy savannah, steppe and meadow. Reforestation sites are sometimes less drained, sometimes very poorly drained due to the unfavorable structure and texture of the soils, in certain sites in the region. In addition, only the sites of Djiddel and Gawel 2 among the Diamaré sites have a better level of canopy, with an average regeneration rate of 36.11%. In Mayo-Kani, only the sites of Moumour, Kéra, Bipaing, Piwa, Mindif and Laf have a better level of canopy, with an average regeneration rate of 47.70%. In Mayo-Tsanaga, only the Boula-Mokong site has a better level of canopy, with an average regeneration rate of 44.66%. In Mayo-Danay, only one site has a better level of canopy, namely the Daiba-Kalfou site. Furthermore, sites in this department have an average regeneration rate of 49.25%. In Logone and Chari, most of the sites have an acceptable level of canopy since no site in this department has a very appreciable level of canopy. However, sites in this department have an average regeneration rate of 39%.

Published: January 2025

Acute kidney injury (AKI) is a critical condition with delayed diagnosis when relying solely on plasma creatinine levels. This study investigates the role of soluble urokinase plasminogen activator receptor (SuPAR) as a biomarker for early prediction of AKI in ICU patients. Results from a prospective observational study of 30 patients indicate that elevated SuPAR levels at 24- and 48-hours post-ICU admission strongly correlate with the incidence of AKI, demonstrating superior predictive power compared to traditional markers. These findings suggest that SuPAR measurements could be instrumental in the early detection and management of AKI, potentially improving patient outcomes. The mean age of participants was 51.13 ± 5.61 years; 60% were male. Hypertension (HTN) was the most prevalent comorbidity (43.3%), and the mortality rate was 30% in the entire cohort. No significant differences in age, gender, or medical history were found between AKI and control groups. SuPAR levels were significantly elevated in the AKI group across all time points. At 48 hours, AKI cases had SuPAR levels of 7.25 ng/dL compared to 5.3 ng/dL in controls (p < 0.001). A strong positive correlation was observed between suPAR levels and serum creatinine at 24 hours (r = 0.62, p < 0.001) and 48 hours (r = 0.678, p < 0.001). suPAR showed potential as a predictive biomarker for AKI progression. Mortality was higher in the AKI group (45.45%) compared to controls (21.05%), but the difference was not statistically significant (p = 0.225). The BUN increased from 8.49 mmol/L at 12 hours to 9.21 mmol/L at 48 hours. Serum suPAR levels rose from 5.14 ng/dL to 6.01 ng/dL during the 48-hour interval. No significant differences were identified between the control and AKI groups for age, gender, or medical history. No significant difference was seen between the groups concerning TLC and PLT levels at different time periods. BUN levels were markedly elevated in the AKI group relative to the control group at all time intervals, with the most pronounced disparity after 48 hours (10.93 vs. 8.21 mmol/L), yielding p-values of 0.007, 0.006, and 0.005 after 12, 24, and 48 hours, respectively. Serum creatinine levels were markedly elevated in the AKI group relative to controls at all time intervals. At 12 hours, creatinine levels in the AKI group were 1.22 mg/dL, but in the control group they were 0.85 mg/dL (p<0.001). suPAR levels were markedly increased in AKI sufferers relative to controls at all time intervals. At 12 hours, AKI cases exhibited suPAR levels of 5.67 ng/dL compared to 4.84 ng/dL in controls (p-value = 0.008). The disparity escalated after 48 hours, with AKI cases exhibiting 7.25 ng/dL in contrast to 5.3 ng/dL in controls (p-value <0.001).

Toxic activity has been demonstrated in extracts of Myrica spathulata Mirb. (or Morella spathulata) stem bark, a Myricaceae endemic to Madagascar. A purification process involving ethanol precipitation, dialysis and n-butanol fractionation yielded a partially purified extract (E3) from a hot aqueous crude extract (CE). The purification yield from CE was 29.87%. The active principles were thermostable, soluble in water, ethanol, but not in butanol, precipitable by neutral lead acetate and did not pass through the dialysis membrane (15,000 Da). Phytochemical screening of the partially purified extract (E3) revealed the presence of tannins, phenolic compounds, deoxyoses, leucoanthocyanins and unsaturated sterols. Mice administered intraperitoneally E3 at a lethal dose of 1087.8 mg/kg developed symptoms suggestive of damage to the nervous system and kidneys. The LD50 (24 h) was estimated at between 875.99 mg/kg and 877.8 mg/kg. In vitro, active ingredients lysed sheep red blood cells. CE was also toxic to tadpoles (LC50 24 h = 1.89 mg/ml). Fish Cyprius carpio were highly sensitive even at very low concentrations (0.12 μg/ml). CE had no effect on Culex quinquefasciatus mosquito larvae. It inhibited the germination of various seeds, and the growth of young seedlings of Oryza sativa (Monocotyledon) and Phaseolus vulgaris (Dicotyledon). Both CE and E3 were active against Staphylococcus aureus and Klebsiella pneumoniae.

Abstract Observations at UPT SDN 51 Gresik obtained data from 20 students, only 2 students achieved the KKTP in the Javanese language subject with basic upload material. The reason is that there is no learning media that motivates students to participate in the learning process. Interesting learning media can motivate students to follow the learning process. The research aims to determine the level of effectiveness of PBL-based E-Book s in Javanese language learning in grade IV elementary schools. This type of research is mix methods. Quantitative data was collected using pretest-posttest questions, while qualitative data was collected using observation sheets. The design of this research is OneGroup Pretest-Posttest. 20 students in class IV UPT SDN 51 Gresik were the subjects of this research. Data were collected using pre and posttest questions and observation sheets. The research results indicate that there is a comparison of the average student learning outcomes before and after using PBL-based E-Book  media. This difference is shown by the value t = -18.242 and p = 0.000. A negative t value indicates that student learning outcomes after implementing PBL-based E-Book s have increased compared to student learning outcomes before implementing PBL-based E-Book s. A very small p value (<0.05) indicates that the difference in student learning outcomes is significant. The average Javanese learning outcomes for class IV students after implementing E-Book s is higher than the average learning outcomes for students before implementing E-Books. This proves that PBL-based E-Book s are effectively implemented in Javanese language learning in class IV elementary schools, proven by increasing student learning outcomes after using PBL-based E-Books.

Published: January 2025

This study explores the relationship between psychological well-being, self-compassion, and the experience of quarter life crisis (QLC) among students in the Department of Guidance and Counselling at the State University of Malang (classes of 2020 to 2023). QLC is a period of anxiety and uncertainty commonly faced by individuals transitioning into early adulthood, marked by fear of the future and indecision. The research aims to determine how psychological well-being and self-compassion can reduce the effects of QLC in university students. Using a correlational design, the study sampled 86 students, selected through proportionate stratified random sampling. The Psychological Well-Being Scale, Self-Compassion Scale, and Quarter Life Crisis Scale were used for data collection. Analysis showed that both psychological well-being and self-compassion had a significant negative impact on QLC. Higher levels of psychological well-being and self-compassion were linked to lower QLC levels, with psychological well-being contributing 53.8% and self-compassion contributing 49.1%. Together, these variables explained 59.8% of the variation in QLC. The findings highlight the need to promote psychological well-being and self-compassion in education to help students cope with QLC. Guidance and counselling programmes can focus on these areas to support students' emotional resilience, self-acceptance, and decision-making. This research adds to the understanding of protective factors against QLC, suggesting further exploration of additional variables and different student populations.

Adolescence is a critical developmental phase where career decision-making plays a pivotal role in shaping individuals’ economic stability, personal fulfillment, and societal contributions. This research addresses the challenges adolescents face in career planning, particularly in Indonesia, where structured career counseling frameworks are limited. Existing approaches often neglect the emotional and social dimensions of decision-making, resulting in increased career indecision and misalignment between aspirations and opportunities. While global research highlights the transformative potential of integrating social and emotional support into career counseling, these practices remain underdeveloped in Indonesian educational settings This study aims to fill this gap by developing a context-specific counseling module tailored to Indonesian high school students. Employing a Research and Development (R&D) methodology, the study integrated self-assessment tools, emotional regulation strategies, and goal-setting guidelines to address cognitive and emotional barriers in career decision-making. The module was validated through expert reviews and field testing with high school students, achieving high ratings for its relevance, clarity, and usability. The findings reveal significant improvements in students’ confidence, decision-making skills, and career readiness, underscoring the effectiveness of incorporating social and emotional competencies in career counseling. The research contributes to theoretical discourse by applying Social Cognitive Career Theory and Trait and Factor Theory to explore the interplay between individual attributes and environmental factors in career development. While the study demonstrates promising outcomes, it acknowledges limitations, such as its focus on a specific population and the absence of longitudinal assessments. The research provides a scalable framework that bridges critical gaps in Indonesian career counseling and offers valuable insights for global applications in similar contexts.

Tax information systems, such as e-Filing and e-Billing, are important innovations in modernizing tax administration in Indonesia. This study aims to analyze the role of these systems in improving taxpayer compliance. The method used is descriptive qualitative with a case study approach, using secondary data from official reports and scientific publications. The results show that e-Filing makes it easier to report tax returns online, reduces administrative errors, and speeds up the reporting process. Meanwhile, e-Billing facilitates electronic tax payments, increases efficiency, and ensures the accuracy of transaction data. Nevertheless, the implementation of these systems faces challenges such as low digital literacy, technical constraints, and access gaps in remote areas. These factors hinder equitable adoption, especially among MSMEs and rural communities. This study concludes that e-Filing and e-Billing systems contribute significantly to improving taxpayer compliance, provided that these challenges can be overcome through digital education, infrastructure improvements, and technical support. Thus, these systems not only support the achievement of tax revenue targets, but also increase taxpayers' confidence in the transparency and accountability of tax services in Indonesia.
Exploring the functionality and utilization potential of ChatGPT-4o in mathematics education: Focusing on 7th-grade mathematics
Authors:   The Korean School Mathematics Society, Park Jeongmin , Son Hongchan
Published: January 2025

This study analyzed errors and improvements in mathematical problem-solving using ChatGPT-4o to explore the potential applications of generative AI like ChatGPT in education. To achieve this, the research examined ChatGPT-4o’s accuracy across five major units of the 7th-grade ‘Mathematics 1’ textbook, identified error types based on unit characteristics, and evaluated the effectiveness of prompt engineering. ChatGPT-4o demonstrated an accuracy rate of 51.76% on major unit assessment problems from 10 versions of the 7th-grade ‘Mathematics 1’ textbook under the 2015 Revised Curriculum. Among the units, the ‘Expressions and Equations’ unit showed the highest accuracy rate, while the ‘Statistics’ unit had the lowest. In terms of error types, ‘problem recognition errors’ were most common in the ‘Numbers and Operations’ and ‘Expressions and Equations’ units. ‘Graph recognition errors’ were predominant in the ‘Coordinate Plane and Graphs’ and ‘Statistics’ units, while ‘diagram recognition errors’ were frequent in the ‘Geometry’ unit. Prompt engineering improved accuracy for identical problems but had little effect on similar problems. A comparative analysis with earlier models also revealed that ChatGPT-4o showed improved accuracy. Despite current limitations, the rapid development of ChatGPT suggests its potential for use in classroom settings in the near future, emphasizing the need for further research.

This study developed and validated affective domain assessment tools to enhance the programs at the GyeongNam Mathematics Culture Center. The affective domains included perception of mathematics, growth mindset, interest, sense of accomplishment, and self-efficacy, with key factors selected through the Delphi method. The developed tools were administered to elementary and middle school students through preliminary and main tests to verify reliability and validity. The results indicated positive changes in most affective domains, with particularly high scores in sense of accomplishment and situational interest. These results demonstrate that changes in students' affective domains through the Gyeongnam Mathematics Culture Center's summer camp and school experiential math programs can be revealed using the assessment tool developed in this study. However, some limitations were identified in the items measuring perception of mathematics, indicating the need for further revision. This study is expected to serve as a crucial resource for analyzing and improving the effectiveness of the programs at the GyeongNam Mathematics Culture Center.

Authors:   The Korean School Mathematics Society, Choi Jisun , Sunwoo Jin
Published: January 2025

Although the use of educational technologies in mathematics teaching is gradually increasing, research on teachers' perceptions of mathematics teaching using these technologies is limited. This study developed a professional development program to train in-service primary school teachers to effectively integrate educational technologies into their mathematics teaching. It analysed how teachers' professional noticing changed as a result of participating in this program. As part of the program, participants wrote an analysis paper after observing mathematics lessons before and after the program, and they compared their papers at the end of the program. The study found that the professional development program enabled teachers to focus more on the purpose and intention of using educational technology in mathematics teaching. However, there was a slight decrease in the tendency of teachers to propose new alternatives for the use of educational technologies or other teaching strategies. The main elements of teachers' change are teacher's considering the purpose of technology in mathematics teaching and focusing on students' mathematical thinking. Based on the findings of this study, implications for teachers' education in integrating educational technologies in mathematics teaching were discussed.
