Modeling On-road Trajectories with Multi-task Learning
Authors: Liu Kaijun , Ruan Sijie , Long Cheng , Yu Liang
Published: November 2024

With the increasing popularity of GPS modules, there are various urban applications such as car navigation relying on trajectory data modeling. In this work, we study the problem of modeling on-road trajectories, which is to predict the next road segment given a partial GPS trajectory. Existing methods that model trajectories with Markov chain or recurrent neural network suffer from various issues, including limited capability of sequential modeling, insufficiency of incorporating the road network context, and lack of capturing the underlying semantics of trajectories. In this article, we propose a new trajectory modeling framework called Multi-task Modeling for Trajectories (MMTraj+), which avoids these issues. Specifically, MMTraj+ uses multi-head self-attention networks for sequential modeling, captures the overall road network as the context information for road segment embedding, and performs an auxiliary task of predicting the trajectory destination information (namely the ID and bearing angle) to better guide the main trajectory modeling task (controlled by a carefully designed gating mechanism). In addition, we tailor MMTraj+ for the cases where the destination information is known by dropping its auxiliary task of predicting the trajectory destination information. Extensive experiments conducted on real-world datasets demonstrate the superiority of the proposed method over the baseline methods.

Published: November 2024

The control of antibiotic resistance is at an alarming stage, making the detection of antibiotics as utmost importantance. A sono-chemically-synthesized reduced-graphene oxide-yttrium oxide nanocomposite (rGO@Y2O3 NC) was used to develop an effective electrochemical immunosensing platform for gentamicin detection. The rGO@Y2O3 NC was characterized using different techniques, providing insights into its structural and functional properties. The detection was carried out on a carbon screen printed electrode modified with rGO@Y2O3 NC using differential pulse voltammetry technique. The rGO@Y2O3 NC helped to enhance the electrochemical activity and the functional groups present on rGO helped in efficient electrostatic immobilization of the antibody. Protein kinase A triggered the immunologic interaction and hence helped in achieving higher sensitivity. The developed immunosensor exhibited an impressive limit of detection of 0.457 pM, with a wide range of detection from 1 pM to 100 μM with a sensitivity of 7.03 μA pM−1 cm−2, representing a substantial enhancement over current technologies. Furthermore, the immunosensor demonstrated practical applicability by effective performance in spiked milk and tap water samples. This highlights its potential for real-world applications in monitoring antibiotic use and ensuring water and food quality control according to regulations.

Authors: Dadi Sri Satya Omkar , Gururani Chaitanya , Garg Girish Kant , Patel Divyansh
Published: November 2024

The study demonstrates an in-house developed eco-friendly vibration-assisted electrochemical polishing (ECP) process, where the electrolyte flushing with the squeezing action of the vibrating tool eliminates the electrolytic by-products in the inter-electrode gap (IEG). A two-dimensional numerical model is developed to study the squeezing effect on changing bubble faction, anodic dissolution, and current density distribution. The effect of process parameters such as current density, electrolyte flow velocity, IEG, vibration amplitude of the tool, and vibration speed is analysed based on the experimental design matrix of response surface methodology (RSM) for minimising average surface roughness (Ra) of SS 304 component fabricated by electrical discharge machining. The numerical results indicated an increased flow velocity at IEG due to the vibration, resulting in an effective flushing of generated gasses. Current, IEG, vibration speed of the tool, vibration amplitude, and interaction between current-IEG, current-vibration speed, and IEG-vibration speed are identified as the most influential parameters by implementing the analysis of variance. The parameters are optimised using RSM, leading to a 96.71% reduction in Ra value and a 62.54% lower Ra value than the ECP without vibration, indicating the effectiveness of vibration-assisted ECP to achieve a high surface finish using eco-friendly electrolytes.

Authors: Yamamoto Rei , Natsui Shungo , Ito Akihisa , Hayasaka Miho , Nogami Hiroshi
Published: November 2024

A rotating basket cathode improved the TiO2-reduction efficiency by 6.5-fold and accelerated the electrolysis of molten CaCl2-CaO at 1173 K in an Ar atmosphere. Promoting dissolution of the CaO byproduct and mass transfer near the cathode was effective for TiO2 reduction and α-Ti deoxidation. The reduction efficiency can be predicted by optimizing the rotational speed and pulse rotation.
Understanding Early Failure Behavior In 3D-Interconnects 2: Empirical Modeling of Broadband Signal Losses In TSV-Enabled Interconnects
Authors: Coakley Kevin J. , Kabos Pavel , Moreau Stéphane , Obeng Yaw S.
Published: November 2024

We present empirical models for measured frequency-dependent insertion loss (|S21|) in a prototypical through silicon via (TSV) enabled 3D-IC from Sematech for characterization of defects formation due to thermal treatment. We measure |S21| on TSV-interconnects, as a function of the extent of thermal annealing. The model parameters are determined with a stochastic optimization implementation of the Levenberg-Marquardt method. Experimental results indicate that loss mechanisms vary with frequency. Hence, we fit our models to a low-frequency (below 3.2 GHz), and to a high-frequency (above 3.2 GHz) subset, respectively. At low frequencies, we attribute variations in frequency-dependent insertion loss to variations in the silicon oxide that isolates the coaxial TSV metal core from the silicon substrate. At frequencies above 3.2 GHz, we attribute variations in insertion loss to other mechanisms including, but not limited to, thermo-mechanical damage concentrated at the surface of the core metal fill and skin effects in the barriers in the TSV. Together with previously published work, we expect this paper to lay the foundation for assessment and improvement of process stability, product reliability, diagnostics, and lifetime predictability. Specifically, we expect the empirical models described in this work to facilitate materials selection and workflow optimization of 3D– interconnect in the semiconductor industry.

Published: November 2024

Carbon quantum dots are activated carbon particles with a size of 1–10 nm that have unique properties such as stable temperature, high stability in the environment, and special chemical properties. Their emission spectrum is always wide and towards long wavelengths with a sharp decrease in intensity. In this work, carbon quantum dots with long emission wavelengths and productivity improvements for biological applications are investigated. In order to reduce the experiments and obtain the best method, the experiment is designed with a mini fever and screened between different factors. In addition, complete factorial screening is performed between three factors (time, OPDA, and ALCL3) and the results demonstrated that time factor and OPDA are more effective. Using a UV–vis fluorescence device, the samples were examined and with the software (Origin Probe), the diagrams of each sample are drawn and their quantum efficiency is recorded. Quantum efficiency is evaluated at 575 nm and 618 nm. Then, the TEM test examined the synthesized nanoparticles’ size. The average particle size synthesized in this project is reported to be about 3 nm. The effect of synthesized carbon quantum dots on fibroblast cells is investigated and the results demonstrated that the survival of these cells after 24 h of incubation with synthesized carbon dots could be more than 90%. As a result, these nanoparticles can be used in biological applications such as bioimaging as a diagnostic sensor for methylene blue. On the other hand, it was found that the nanoparticles synthesized in the presence of HCL have higher strength and wavelength.

Published: November 2024

As the Internet of Things (IoT) advances, low‐cost, intelligently networked wireless sensor networks (WSNs) are being developed and deployed at cloud edge locations to enable new Internet‐based services. However, energy consumption in these networked smart sensors is a significant concern. This work focuses on using an ultra‐wideband (UWB) multiple‐input‐multiple‐output (MIMO) antenna sensor printed on optically transparent polydimethylsiloxane (PDMS) material to reduce energy consumption in WSN nodes. The antenna sensor structure consists of two rectangular‐shaped printed monopole antenna elements (AEs) and four PIN diodes used for switching purpose. A narrow strip is also integrated in the AE to notch WLAN band. The antenna sensor operates in a variety of modes, achieved by varying the ON/OFF states of PIN diodes. The frequency range covered by the antenna is 3.2–11 GHz when all four PIN diodes are turned ON. The overall measurements of the suggested antenna are 31 mm × 31 mm × 1.5 mm. It performs well in terms of diversity, with a minimum isolation of 20.7 dB over the whole operating band. The outcomes of the simulation and the measurements agree fairly well.
An Ensemble Method for Soil Parameter Prediction Based on Multisource Data Fusion
Authors: Wang Mingyuan , Zeng Shaoxiang , Zhang Zuguo , Chen Songting , Wang Jun
Published: November 2024

Site investigation is crucial in geotechnical engineering. The cone penetration test (CPT) and the multichannel analysis of surface waves (MASWs) are widely used as geotechnical and geophysical methods, respectively. CPT offers high precision but requires a high cost and only provides soil information at limited locations. In contrast, MASW covers a broad range of soil information but has less accuracy compared to CPT. This study proposes a novel ensemble prediction method that fuses both CPT and MASW data to overcome the limitations of using either dataset alone. The method employs random forest (RF) and gradient boosting decision tree (GBDT) to achieve the transformation between the shear velocity and cone tip resistance (Vs–qc) and the prediction of qc at unknown locations. Unlike traditional empirical regression models, this method provides more accurate and reliable predictions by leveraging the complementary strengths of CPT and MASW. The proposed RF‐GBDT ensemble model is validated using data from the New Zealand Geotechnical Database. The results show that the established RF‐GBDT ensemble model outperforms simple empirical regression models and various popular machine learning models in the Vs–qc transformation and in predicting qc at unknown locations. Specifically, integrating MASW data increases the R2 at location CPT3 from 0.477 to 0.758, demonstrating that the proposed method can improve the predictions of soil parameters in areas with sparse data.

Published: November 2024

The bearing capacity of traditional prestressed high‐strength concrete (PHC) pipe pile is hampered by the poor mechanical properties of surrounding soil in soft soil areas, and the PHC nodular pile can improve the behavior of pile foundation in soft soils. The PHC nodular pile installation process will induce larger disturbance to the surrounding soil compared to the PHC pipe pile, and there is little research on the installation effect of the PHC nodular pile. In this paper, the coupled Eulerian‐Lagrangian (CEL) finite element method was adopted to simulate the penetration process of PHC nodular piles and pipe piles in soft soil. The radial stress and displacement in soil induced by the PHC nodular pile and pipe pile and the soil resistance at different parts of the PHC nodular pile were analyzed. The simulation results showed that the penetration resistance of the PHC nodular pile was larger than that of the PHC pipe pile. The penetration resistance of PHC nodular piles was mainly provided by the pile shaft resistance. The uplift height of soil surface caused by the PHC nodular pile and pipe pile penetration was approximately the same. The influence range of compaction effect for PHC nodular pile and pipe pile was both concentrated on 10R (R is the pile diameter).

Published: November 2024

Aflatoxin contamination in food poses a significant health risk, especially in low‐ and middle‐income nations. While there is a need to increase food safety, there is a lack of aflatoxin‐related sociodemographic factors, knowledge, attitudes, and practices (KAPs) among aflatoxin‐risk populations. The study is aimed at collecting information from the vendors and consumers of maize grains to investigate their sociodemographic factors and KAPs of aflatoxin contaminations in Kenya’s small‐ and medium‐sized informal markets. A cross‐sectional survey using a simple random sampling approach was conducted from July 2022 to August 2022 in Meru County, Kenya. Vendors and consumers of maize grain markets were interviewed using face‐to‐face interviews and semistructured questionnaires. Females were the predominant gender among the maize grain vendor (82.7%) and consumer (83.72%) participants. Most vendors (95.7%) and consumers (94.2%) have formal education. Almost all vendors (96.2%) and consumers (95.3%) check for maize selling and purchasing quality. The proportion of visibly mouldy grains (25.5%, 29.0%), moisture level (20.2%, 12.9%), and size of grains (11.4%, 14.8%) were the commonest quality dimensions checked by vendors and consumers, respectively. Most vendors (86.8%) and consumers (70.9%) have heard about aflatoxin, but only 48.2% of the vendors and 52.1% of the consumers were aware and could mention the correct aflatoxin health effects. Vendors’ and consumers’ KAPs on aflatoxin varied significantly (p < 0.05) across subcounties, education levels, genders, and ages. Promoting public awareness, building capacity, and implementing aflatoxin‐related policies at all levels are crucial to ensure food safety.

Published: November 2024

Erythropoietin (Epo), a glycosylated protein categorized as a member of the cytokine family, is responsible for the modulation of erythrogenesis. Besides this, the nonhaematopoietic effects of Epo are associated with tissue‐protective activity via an antiapoptotic pathway. This function of Epo is linked with its heterodimeric form, i.e. EpoR/βcR belonging to the cytokine family as well. Both receptors are dissected into three domains: extracellular (also known as ligand‐binding domain), transmembrane and cytoplasmic domain. The transmembrane and cytoplasmic domains are assumed to play a paramount role in dimerization and tissue protection. However, the tertiary structure of cytoplasmic domains of both EpoR and βcR was not reported in the literature. Inspired by the potential therapeutic applications, we aimed to investigate the interaction pattern of EpoR/βcR using in silico tools. Cytoplasmic domains of EpoR and βcR were modelled, structural refinement was carried out through Rosetta, and these were then quality verified by well‐known quality matrices. The observed results were found to be structurally consistent with the amenable geometry showing stereochemical sustainability. The modelled cytoplasmic domains were then successfully merged with the remaining domains (extracellular and transmembrane domains) of the respective receptors through MOEv2019.01 and Modeller. The complete structures of EpoR and βcR were subjected to geometry optimization and energy minimization via dynamic studies. The refined structures were subjected to protein–protein docking to yield the heterocomplex. Here, we report on the optimized structure coordinates of EpoR/βcR, the plausible electrostatic interactions involving G191, V206, T214, S241, T244, E336, R337, M342, G348, T349, E362 and K373 of EpoR and D336, S337, Y338, K333, R391, M426, H494, Q495, S717, S722, Y750 and G758 of βcR. Subsequently, we performed screening utilizing the StraPep database to identify Epo mimetic agents with the potential to enhance their tissue‐protective effects. Following the virtual screening, four hits (4HQX, 4XO8, 1TPO and 3EZM) were obtained based on the binding affinity and protein–ligand interaction fingerprinting (PLIF). The stability exhibited by the four selected peptides in the binding site of the EpoR/βcR heterocomplex became visible during visual inspection. We propose that the presented model can be harnessed for future characterization studies.

Published: November 2024

Introduction: A minority of addiction patients receive appropriate treatment directly from trained professionals in addiction medicine. Most countries have not recognized addiction medicine (AM) as a specialty in its own right or within psychiatry/other specialties. Therefore, the effectiveness and organization of AM training around the world need to be improved. Unfortunately, standard instruments are rarely used in most studies to assess training needs. This study aimed to determine international competencies in AM among professionals in as many countries as possible using a standard instrument such as the AM Training Needs Assessment (AM-TNA). Method: We examined competencies in AM with the AM-TNA using an online survey. A General Competency Level in Addiction Medicine (GLOCIAM30) was calculated by dividing the total score by the number of 30 items. This GLOCIAM30 was used to measure the general level of competency in AM and to compare individual competencies. Results: One hundred ninety-nine respondents from 45 countries completed the survey. Ninety-five of the 199 respondents (49.0%) had a GLOCIAM30 higher or equal to 4 (fairly competent). The highest skill level was found for the competency “Assessing substance use problems by taking the patient’s history.” Nine of the 45 countries had 8 or more respondents (n = 129). After post hoc analysis, there was no difference between these countries. Respondents could reasonably estimate whether the competency level in their country was higher or lower than the world average. Conclusions: This study is the first international attempt to examine competencies in AM. Although a much larger study population is needed to establish an overall goal for competencies in AM, our study provided an initial direction for such a gold standard in benchmarking procedures.

Introduction: The natural history, the progression of a disease process in an individual over time, has not yet been fully elucidated in hidradenitis suppurativa (HS).
In this large multicenter study, we aimed to investigate the natural history of HS and its gender differences.
Methods: This cross sectional study included 827 patients. The chronological order of the clinical manifestations for each patient were recorded retrospectively. Sociodemographic characteristics, triggering factors, clinical, treatment, and prognostic features were also evaluated.
Results: The mean age of disease onset was significantly younger in women than in men (22.42±9.28 vs. 27.06±20.56, p<0.001) and those with a family history (p<0.0001). The mean disease duration was 91.17±83.64 months. The most common symptom was purulent discharge (81%). The mean duration of abscess was shorter in women than in men (3.11±2.65 vs. 3.75±3.75, p=0.01). The axilla was the most common onset area followed by the inguinal and gluteal regions. The disease ran a more severe course in men. Abscess/inflammatory nodule was defined in the last 6 months in 88.6% of the patients; however, the first 5 years of the disease were the most active disease period in 67.5% of the patients. Multivariate analysis revealed being male, older age, family history, involvement of the axillary, inguinal and perianal regions independently associated with HS severity. While antibiotic use was the most important factor in improving the disease symptoms, stress was the most common aggravating factor. Biological therapy in men, laser epilation and pregnancy in women were significant alleviating factors. Whereas, weight gain was a more common aggravating factor for women.
Conclusion: HS shows a relentlessly progressive course with inflammatory attacks, but the first years of the disease are the most active period. This study confirms that environmental and hormonal factors may play an important role in the disease course, probably with other endogenous or exogenous factors.

Malaysia’s education development plan 2013-2025 promotes 21st-century learning. Instruction, learning, and school assistance are the key focus. This study selected Rompin State instructors to assess their 21st-century education ability, perspective, and application. The questionnaire was the main data-gathering tool in this quantitative investigation. Standard random sampling chose 152 school teachers. This study used Pearson correlation and t-test for descriptive and inferential analysis. The results showed reasonable knowledge, attitude, and practices (mean=2.95, standard deviation=0.22, 2.94, 0.23, 2.90, 0.29). The t-test showed significant differences in knowledge (t=-2.11, df=157, p 0.05) and attitude (t=-2.26, p 0.05) but not in practice (t=-1.81, p>0.05). Using Pearson correlation analysis, knowledge, and behaviors were moderately positively correlated (r=0.677, p<0.01), whereas attitudes and practices were strongly positively correlated (r=0.837, p<0.1). Teachers have modest knowledge, attitudes, and practices. Teachers must frequently take short courses to improve their 21st-century education. Mandatory authorities and scholars will help instructors professionally grasp 21st-century education. This study found that teachers with 21st-century education literacy can improve their knowledge, attitude, and practice and regularly apply it to their teaching.

The current research aims to assess the psychometric properties of the emotional intelligence scale among university students in Indonesia. This research used a survey design. The current research participants were 288 university students in Palembang, West Nusa Tenggara, Kupang, Yogyakarta, and Jakarta, Indonesia. Two procedures were used to analyze the data: exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The results showed that EFA with comprehensive techniques that compromise parallel analysis yielded a 5-factor solution: empathy with five items, handling relationships with five items, motivation for oneself with six items, self-awareness with seven items, and managing emotion with eight items. The five factors solution was confirmed through CFA with the value: Chi square=2.631, Tucker-Lewis’s index (TLI)=.804, comparative fit index (CFI)=.823, root mean square error of approximation (RMSEA)=.075, and standardized root mean residual (SRMR)=.743. The scale validation and reliability were tested through average variance extracted (AVE) with the value ranged from 0.271 to 0.594, construct reliability (CR) with the value ranged from 0.706 to 0.879, and Cronbach’s alpha with the value ranged from 0.706 to 0.879. Therefore, based on psychometric analysis, the scale is valid and reliable to be used in measuring emotional intelligence among university students in Indonesia.

Published: November 2024

Vocational education (VE) is one of the institutions that must answer environmental problems by providing green job skills to its students. However, VE in Indonesia still experience various obstacles in providing this provision, so the aim of this research aims to analyze the extent of the level of green skills (GS) in teachers and students in this country, which includes the dimensions of cognitive, interpersonal and intrapersonal competence as an illustration for developing a priority scale for improvement. In addition, examining the differences and correlations between dimensions and the contribution of dimensions to GS as a whole is an additional goal. The survey method was carried out using a generic GS questionnaire instrument in VE that have Adiwiyata status. Data were analyzed using three stages: descriptive analysis, ANOVA-post hoc Tukey test, and path analysis. As a result, students’ GS still show a low category, while teachers get a high category. Between dimensions show no significant differences. Finally, all competencies have a significant relationship and can construct overall GS. These results indicate that there is still a need to strengthen teacher competencies in GS-based learning management and strengthen collaboration with all levels of society.

Published: November 2024

Algebra is the major branch of mathematics that deals with numbers, and symbols are mostly used in problem-solving. Students often struggle to learn mathematics due to the difficulties of solving algebraic problems at the secondary level. Several factors affect student problem-solving achievement (PSA). The present study aims to examine the mediating effect of study habits (SH) in the relationship between parental involvement (PI) and algebraic PSA. For this purpose, a study habits scale and a parental involvement scale are used, and a problem-solving test is done for algebraic problem-solving. In this correlational study, Baron and Kenny’s series of regression models is used to test the mediating effect of SH. The findings revealed that that PI, SH and algebraic PSA are positively correlated. Also, it is confirmed that SH mediates the relationship between PI and algebraic PSA because there is no longer any significant effect of PI on PSA after SH is included in the model. It is recommended that students’ problem-solving skills be developed through their better study habits. Increasing parental support may promote students better SH, which in turn better achievement in problem-solving. Parents and teachers should monitor and encourage students’ study habits for better performance in problem-solving and mathematics as a whole.

Positive psychology is transformative in developing individuals’ self-esteem, life satisfaction, subjective happiness, and social competence. The objectives of the present study were to investigate the impact of self-esteem and overall life satisfaction on perceived social competence in university students while measuring subjective happiness as a mediator and gender differences across variables. A sample of 1,168 participants was selected using purposive and random sampling techniques across universities in Pakistan. The study design was correlational with a quantitative method. Four scales, the Rosenberg self-esteem scale (RSE), satisfaction with life scale (SWLS), subjective happiness scale (SHS), and perceived social competence scale (PSCS), were administered to measure the variables. Pearson correlation and mediation models were used to test the hypotheses. The analysis indicated that subjective happiness mediated the relationship between self-esteem, perceived social competence, life satisfaction, and perceived social competence. Moreover, the results showed that males scored higher than females in terms of levels of self-esteem. No significant gender difference existed in life satisfaction, subjective happiness, and perceived social competence. These findings may significantly enrich the literature on positive psychology in Pakistani university students and can assist universities in their mental health programs and sustain students’ healthier well-being.

From a preliminary analysis of the scientific literature, it can be seen that knowledge of science, technology, engineering and mathematics (STEM) has a positive impact on the development of necessary skills in students’ professional activities. However, there are very few studies on the effectiveness of using STEM elements in developing the creativity of future physics teachers in specialized fields. The aim of this study was to develop digital resources as a basis for STEM knowledge and to assess their impact on the development of students’ creativity. Based on special principles of education, constructive method in teaching, modeling methods, digital educational resources were developed and an evaluation experiment was conducted. The experiment involved 86 students (40 in the control group and 46 in the experimental group), and compared the results of traditional learning and STEM learning by using digital resources. The results of the questionnaire assessment showed that STEM education can be very effective in developing students’ creativity. The pedagogical experiment was implemented during the teaching of the author’s course entitled “The physical foundations of tribology.” The results of the study contribute to finding solutions to scientific problems in the field of teaching tribology.

In this study, it was aimed to determine the pedagogical principles for building functional science literacy of school children in line with the Program for International Student Assessment (PISA) by examining the performing countries in PISA. The statistical results of the PISA results reports of China, Singapore, Hong Kong and Estonia were compared with the results of Kazakhstan. It was concluded that students in the top-ranked countries actively participate in scientific activities, enjoy practicing scientific activities, exhibit high-level cognitive skills, test and monitor the results of scientific research, and compete in national and international activities. The economic status of the family, learning environment, discipline, school equipment, and the number of teachers in the school are among the factors affecting children’s science literacy. Teachers’ continuous participation in in-service trainings, keeping their motivation at a high level, choosing different teaching methods, encouraging students to conduct research and activating high-level cognitive skills were considered among the most important reasons for good results in science PISA research. It is recommended that countries that want to rank higher in an international platform such as PISA should implement student-centered activities in their educational reforms and create educational environments where students can test their high-level skills.

Authors: Jiang Jinchuan , Abu Ziden Azidah
Published: November 2024

This paper conducts a need analysis study to identify the requirements for developing a competency model for teachers implementing game-based learning (GBL) in Chinese secondary schools. Additionally, it investigates the practices and challenges of teachers while implementing this pedagogical approach. Through a quantitative survey involving 384 teachers, key findings reveal significant challenges, such as technological issues, limited instructional time, a lack of high-quality games aligned with the curriculum, and inadequate teacher training. The majority of teachers expressed a positive attitude towards game-based learning but reported limited classroom usage due to these obstacles. The results highlight the need for the development of a competency model tailored to game-based learning teachers, emphasizing the importance of structured training opportunities. Such a model would provide essential guidance and support, enabling teachers to enhance their competencies and effectively integrate game-based learning into their teaching practices. Consequently, the next step of this research is to design and develop a comprehensive competency model that encompasses both technological and pedagogical skills, which will aim to enhance teacher preparedness and improve the integration of game-based learning in education, ultimately benefiting student engagement and learning outcomes.
