With a sample of 54 teachers, a structured questionnaire was administered to assess their competencies. The results revealed a direct positive correlation between the use of technologies and digital competencies, with a Spearman's Rho coefficient of 0.877, indicating a significant relationship. Correlations between the use of information technologies and the dimensions of digital competencies ranged from moderate to high. Significant correlations were observed in areas such as problem-solving (Rho=0.457), information and digital literacy (Rho=0.633), and security (Rho=0.743), among others. These findings suggest that, despite limited experience and limited knowledge of digital technologies among teachers in the institution, there is a notable relationship between the use of these technologies and their digital competencies. This study underscores the need for further training in information technologies for teachers in non-modernized urban contexts and for those who are older adults with limited prior experience in the digital domain. Enhancing digital competencies is crucial for adapting to the educational challenges in this new era of education</span></p> Lida Vásquez-Pajuelo Jhonny Richard Rodriguez-Barboza Karina Raquel Bartra-Rivero Edgar Antonio Quintanilla-Alarcón Wilfredo Vega-Jaime duardo Francisco Chavarri-Joo Copyright (c) 2024 Lida Vásquez-Pajuelo, Jhonny Richard Rodriguez-Barboza, Karina Raquel Bartra-Rivero, Edgar Antonio Quintanilla-Alarcón, Wilfredo Vega-Jaime, Eduardo Francisco Chavarri-Joo https://creativecommons.org/licenses/by/4.0 2024-02-09 2024-02-09 3 216 216 10.56294/dm2024216 Data lake management using topic modeling techniques https://dm.saludcyt.ar/index.php/dm/article/view/282 <p>With the rapid rise of information technology, the amount of unstructured data from the data lake is rapidly growing and has become a great challenge in analyzing, organizing and automatically classifying in order to derive the meaningful information for a data-driven business. The scientific document has unlabeled text, so it's difficult to properly link it to a topic model. However, crafting a topic perception for a heterogeneous dataset within the domain of big data lakes presents a complex issue. The manual classification of text documents requires significant financial and human resources. Yet, employing topic modeling techniques could streamline this process, enhancing our understanding of word meanings and potentially reducing the resource burden. This paper presents a comparative study on metadata-based classification of scientific documents dataset, applying the two well-known machine learning-based topic modelling approaches, Latent Dirichlet Analysis (LDA) and Latent Semantic Allocation (LSA). To assess the effectiveness of our proposals, we conducted a thorough examination primarily centred on crucial assessment metrics, including coherence scores, perplexity, and log-likelihood. This evaluation was carried out on a scientific publications corpus, according to information from the title, abstract, keywords, authors, affiliation, and other metadata aspects. Results of these experiments highlight the superior performance of LDA over LSA, evidenced by a remarkable coherence value of (0.884) in contrast to LSA's (0.768).</p> Mohamed CHERRADI Copyright (c) 2024 Mohamed CHERRADI https://creativecommons.org/licenses/by/4.0 2024-04-15 2024-04-15 3 282 282 10.56294/dm2024282 Optimizing Energy Consumption in 5G HetNets: A Coordinated Approach for Multi-Level Picocell Sleep Mode with Q-Learning https://dm.saludcyt.ar/index.php/dm/article/view/333 <p>Cell standby, particularly picocell sleep mode (SM), is a prominent strategy for reducing energy consumption in 5G networks. The emergence of multi-state sleep states necessitates new optimization approaches. This paper proposes a novel energy optimization strategy for 5G heterogeneous networks (HetNets) that leverages macrocell-picocell coordination and machine learning. The proposed strategy focuses on managing the four available picocell sleep states. The picocell manages the first three states using the Q-learning algorithm, an efficient reinforcement learning technique. The associated macrocell based on picocell energy efficiency controls the final, deeper sleep state. This hierarchical approach leverages localized and network-wide control strengths for optimal energy savings. By capitalizing on macrocell-picocell coordination and machine learning, this work presents a promising solution for achieving significant energy reduction in 5G HetNets while maintaining network performance.</p> Macoumba Fall Mohammed Fattah Mohammed Mahfoudi Younes Balboul Said Mazer Moulhime El Bekkali Ahmed D.

By eliminating redundant copies of data, it enhances storage efficiency, lowers costs, and minimizes network bandwidth requirements, thereby improving overall performance and scalability of cloud-based systems. The research investigates the critical intersection of data de-duplication (DD) and privacy concerns within cloud storage services. Distributed Data (DD), a widely employed technique in these services and aims to enhance capacity utilization and reduce transmission bandwidth. However, it poses challenges to information privacy, typically addressed through encoding mechanisms. One significant approach to mitigating this conflict is hierarchical approved de-duplication, which empowers cloud users to conduct privilege-based duplicate checks before data upload. This hierarchical structure allows cloud servers to profile users based on their privileges, enabling more nuanced control over data management. In this research, we introduce the SHA method for de-duplication within cloud servers, supplemented by a secure pre-processing assessment. The proposed method accommodates dynamic privilege modifications, providing flexibility and adaptability to evolving user needs and access levels. Extensive theoretical analysis and simulated investigations validate the efficacy and security of the proposed system. By leveraging the SHA algorithm and incorporating robust pre-processing techniques, our approach not only enhances efficiency in data de-duplication but also addresses crucial privacy concerns inherent in cloud storage environments. This research contributes to advancing the understanding and implementation of efficient and secure data management practices within cloud infrastructures, with implications for a wide range of applications and industries.</p> Rajendran Bhojan Manikandan Rajagopal Ramesh R Copyright (c) 2024 Rajendran Bhojan, Manikandan Rajagopal, Ramesh R https://creativecommons.org/licenses/by/4.0 2024-03-30 2024-03-30 3 245 245 10.56294/dm2024245 Social media and education: perspectives on digital inclusion in the university setting https://dm.saludcyt.ar/index.php/dm/article/view/299 <p>Social networks have become pivotal in education, offering opportunities for inclusive learning experiences.

However, scheduling workload in a heterogeneous multi-cloud environment is a complicated process. Users of cloud services want to ensure that their data is secure and private, especially sensitive or proprietary information. Several research works have been proposed to solve the challenges associated with cloud computing. The proposed Adaptive Priority based scheduling (PBS) focuses on reducing data access completion time and computation expense for task scheduling in cloud computing. PBS assigns tasks depending on its size and selects the minimum cost path for data access. It contains a task register, scheduler, and task execution components for efficient task execution. The proposed system also executes a double signature mechanism for data privacy and security in data storage. This study correlates the perfo}rmance of three algorithms, PBS, (Task Requirement Degree) TRD and (recommended a Risk adaptive Access Control) RADAC, in terms of task execution time and makespan time. The experimental results demonstrate that PBS outperforms TRD and RADAC in both metrics, as the number of tasks increases. PBS has a minimum task execution time and a lower makespan time than the othertwo algorithms</p> <p> </p> K.Prathap Kumar R. Rohini Copyright (c) 2023 K.Prathap Kumar, R.

The sample consisted of 55 university professors of both sexes who were administered a questionnaire to assess their level of knowledge about AI, which had adequate metric properties.<br />Results: The level of knowledge about AI was low for 41.8% of professors, regular for 40%, and high for 18.2%. This indicates that there is a significant gap in the knowledge of university professors about AI and its application in education, which could limit their ability to fully leverage AI tools and applications in the educational environment and could affect the quality and effectiveness of teaching. Likewise, it was determined that age and self-perception of digital competencies of professors were significantly associated with their level of knowledge about AI (p&lt;0.05).<br />Conclusions: Peruvian university professors are characterized by presenting a low level of knowledge about AI. Therefore, it is recommended to implement training and professional development programs focused on artificial intelligence, in order to update and improve their skills in this field.</p> Edwin Gustavo Estrada-Araoz Yesenia Veronica Manrique-Jaramillo Víctor Hugo Díaz-Pereira Jenny Marleny Rucoba-Frisancho Yolanda Paredes-Valverde Rosel Quispe-Herrera Darwin Rosell Quispe-Paredes Copyright (c) 2024 Edwin Gustavo Estrada-Araoz, Yesenia Veronica Manrique-Jaramillo, Víctor Hugo Díaz-Pereira, Jenny Marleny Rucoba-Frisancho, Yolanda Paredes-Valverde, Rosel Quispe-Herrera, Darwin Rosell Quispe-Paredes https://creativecommons.org/licenses/by/4.0 2024-04-24 2024-04-24 3 285 285 10.56294/dm2024285 Fuzzy Decision-Making Model for the inventory leveling under uncertainty condition https://dm.saludcyt.ar/index.php/dm/article/view/142 <p>&nbsp;&nbsp;&nbsp; The option to create inventory is not always the optimal choice due to the associated expenses and space requirements. Nevertheless, there are instances where a shortage of materials on customer lines can result in substantial financial penalties. This constant contradiction places supply chain managers in a perplexing predicament, especially when considering the amplification of inventory through the bullwhip effect as it moves across different stages. Moreover, the uncertain backdrop created by unforeseen events intensifies this already critical situation, compelling managers to seek novel decision-making approaches. These approaches should enable the simulation of risks and the selection of suitable scenarios, particularly within the intricate domain of stochastic and dynamically evolving supply chains. In this study, we introduce a new decision-making model rooted in the fuzzy logic concept introduced by Loutfi Zadeh in 1965. This model is applied to criteria assessed by experts, representing the most pertinent parameters for guiding inventory optimization. The chosen criteria encompass Lead Time, Equipment Production Reliability, and Warehousing Costs. This model exhibits the potential to unearth intricate patterns and associations among variables that conventional statistical methods struggle to reveal. Notably, the integration of fuzzy logic for inventory prediction yields promising outcomes, extendable to the realm of artificial intelligence, where comprehensive inference rules facilitate effective decision-making.</p> <p>&nbsp;</p> Hatim Lakhouil Aziz Soulhi Copyright (c) 2024 Hatim Lakhouil, Aziz Soulhi https://creativecommons.org/licenses/by/4.0 2024-01-11 2024-01-11 3 142 142 10.56294/dm2024142 Analysis of scientific information from a bibliometric approach between Chat GPT and Scopus: A comparative study https://dm.saludcyt.ar/index.php/dm/article/view/252 <p>One of the main challenges faced by teachers, researchers, and students today is efficiently filtering reliable and useful information available on the internet, as well as in scientific academic databases. To address this phenomenon, the bibliometrics tool is used, which involves understanding the number of publications, analyzing them, and determining their trend based on the application of filters and relationships of scientific concepts in specialized topics.

The pipeline includes a number of actions, such as removing social tags, normalizing whitespace, changing all lowercase letters to uppercase, removing stopwords, fixing Unicode issues, contraction unpacking, removing punctuation and accents, and text cleanup. These procedures work together to strengthen the integrity and quality of the input data, which will ultimately improve the efficiency and precision of LLMs. Extensive testing and comparisons with standard techniques show TextRefine's effectiveness with 99% of the accuracy.</p> Ekta Dalal Parvinder Singh Copyright (c) 2024 Ekta Dalal, Parvinder Singh https://creativecommons.org/licenses/by/4.0 2024-05-20 2024-05-20 3 331 331 10.56294/dm2024331 A Study of Factors Influencing Happiness in Korea: Topic Modelling and Neural Network Analysis https://dm.saludcyt.ar/index.php/dm/article/view/238 <p>The aim of this study is to derive the important factors that influence levels of happiness in Korea, and to identify which factors are particularly important among these influencing factors. To achieve this goal, topic modelling analysis, machine learning analysis and neural network analysis methods were utilized. The Netminer 4.5 program was used for topic modelling analysis and machine learning analysis, and SPSS MODELER 18 was used to perform neural network analysis. Two types of analysis data were used in this study. The first consisted of 1,000 papers relating to happiness published in academic journals managed by the Springer publishing company, which were used to derive happiness-influencing factors. The second consisted of a survey conducted in 2020 by the Community Well-being Center of the Graduate School of Public Administration at Seoul National University in Korea. A total of 16,655 people responded to this survey. The analysis results of the study are as follows. Important variables that affect the level of happiness of Korean residents are: family life, social status, income, health, and perceptions of inequality. Analysis using neural network analysis of the most important factors influencing happiness showed that satisfaction with family life had the most important influence. This suggests that policies that can improve the quality of family life, such as family-friendly work environments, childcare support, and domestic violence prevention and response programmes, will become important in the future.</p> Ji-Hyun Jang Nemoto Masatsuku Copyright (c) 2024 A https://creativecommons.org/licenses/by/4.0 2024-03-14 2024-03-14 3 238 238 10.56294/dm2024238 Real-Time Vehicle Detection for Traffic Monitoring: A Deep Learning Approach https://dm.saludcyt.ar/index.php/dm/article/view/295 <p>Vehicle detection is an essential technology for intelligent transportation systems and autonomous vehicles. Reliable real-time detection allows for traffic monitoring, safety enhancements and navigation aids. However, vehicle detection is a challenging computer vision task, especially in complex urban settings. Traditional methods using hand-crafted features like HAAR cascades have limitations. Recent deep learning advances have enabled convolutional neural networks (CNNs) like Faster R-CNN, SSD and YOLO to be applied to vehicle detection with significantly improved accuracy. But each technique has tradeoffs between precision and processing speed. Two-stage detectors like Faster R-CNN are highly accurate but slow at 7 FPS. Single-shot detectors like SSD are faster at 22 FPS but less precise. YOLO is extremely fast at 45 FPS but has lower accuracy. This paper reviews prominent deep learning vehicle detectors. It proposes a new integrated method combining YOLOv3 detection, optical flow tracking and trajectory analysis to enhance both accuracy and speed. Results on highway and urban datasets show improved precision, recall and F1 scores compared to YOLOv3 alone. Optical flow helps filter noise and recover missed detections. Trajectory analysis enables consistent object IDs across frames. Compared to other CNN models, the proposed technique achieves a better balance of real-time performance and accuracy. Occlusion handling and small object detection remain open challenges. In summary, deep learning has enabled major progress but enhancements in model architecture, training data and occlusion handling are needed to realize the full potential for traffic management applications. The integrated method proposed offers improved performance over baseline detectors. We have achieved 99 % accuracy in our project</p> Patakamudi Swathi Dara Sai Tejaswi Mohammad Amanulla Khan Miriyala Saishree Venu Babu Rachapudi Dinesh Kumar Anguraj Copyright (c) 2024 Patakamudi Swathi, Dara Sai Tejaswi, Mohammad Amanulla Khan, Miriyala Saishree, Venu Babu Rachapudi, Dinesh Kumar Anguraj https://creativecommons.org/licenses/by/4.0 2024-04-13 2024-04-13 3 295 295 10.56294/dm2024295 A Progressive UNDML Framework Model for Breast Cancer Diagnosis and Classification https://dm.saludcyt.ar/index.php/dm/article/view/198 <p>According to recent research, it is studied that the second most common cause of death for women worldwide is breast cancer. Since it can be incredibly difficult to determine the true cause of breast cancer, early diagnosis is crucial to lowering the disease's fatality rate. Early cancer detection raises the chance of survival by up to 8%. Radiologists look for irregularities in breast images collected from mammograms, X-rays, or MRI scans. Radiologists of all levels struggle to identify features like lumps, masses, and micro-calcifications, which leads to high false-positive and false-negative rates. Recent developments in deep learning and image processing give rise to some optimism for the creation of improved applications for the early diagnosis of breast cancer. A methodological study was carried out in which a new Deep U-Net Segmentation based Convolutional Neural Network, named UNDML framework is developed for identifying and categorizing breast anomalies. This framework involves the operations of preprocessing, quality enhancement, feature extraction, segmentation, and classification. Preprocessing is carried out in this case to enhance the quality of the breast picture input. Consequently, the Deep U-net segmentation methodology is applied to accurately segment the breast image for improving the cancer detection rate. Finally, the CNN mechanism is utilized to categorize the class of breast cancer. To validate the performance of this method, an extensive simulation and comparative analysis have been performed in this work. The obtained results demonstrate that the UNDML mechanism outperforms the other models with increased tumor detection rate and accuracy</p> <p> </p> G. Meenalochini D.

Artificial intelligence and machine learning algorithms have increased the CVD prediction capability of clinical decision support systems. However, the shallow feature learning in machine learning and incompetent feature selection methods still pose a greater challenge. Consequently, deep learning algorithms are needed to improvise the CVD prediction frameworks. Methods: This paper proposes an advanced CDSS for CVD detection using a hybrid DL method. Initially, the Improved Hierarchical Density-based Spatial Clustering of Applications with Noise (IHDBSCAN), Adaptive Class Median-based Missing Value Imputation (ACMMVI) and Clustering Using Representatives-Adaptive Synthetic Sampling (CURE-ADASYN) approaches are introduced in the pre-processing stage for enhancing the input quality by solving the problems of outliers, missing values and class imbalance, respectively. Then, the features are extracted, and optimal feature subsets are selected using the hybrid model of Information gain with Improved Owl Optimization algorithm (IG-IOOA), where OOA is improved by enhancing the search functions of the local search process. These selected features are fed to the proposed Chaotic Rat Swarm Optimization-based Convolutional Neural Networks (CRSO-CNN) classifier model for detecting heart disease. Results: Four UCI datasets are used to validate the proposed framework, and the results showed that the OOA-DLSO-ELM-based approach provides better heart disease prediction with high accuracy of 97.57%, 97.32%, 96.254% and 97.37% for the four datasets. Conclusions: Therefore, this proposed CRSO-CNN model improves the heart disease classification with reduced time complexity for all four UCI datasets.</p> D Sasirega V Krishapriya Copyright (c) 2024 Sasirega.

It influences patient care quality and staff retention and is shaped by the work environment, working conditions, managerial support, and interactions among colleagues. However, there is limited research specifically addressing the job satisfaction of nurses in Peru, a critical area in health administration. Objective: This study aimed to evaluate the metric properties of the S20/23 job satisfaction scale among Peruvian nurses. Methods: An instrumental research design was employed using a non-probabilistic sample of 325 nurses from two hospitals in Lima, Peru. The Chilean version of the S20/23 scale was used, comprising four dimensions of job satisfaction (relationship with supervision, physical work space, professional fulfillment, and training and decision-making opportunities). Data analysis included descriptive statistics, confirmatory factor analysis (CFA), and reliability tests using Cronbach's Alpha and McDonald's Omega. Results: The CFA revealed a satisfactory fit for the four-dimensional structure with 18 items (χ2 = 387.290, df = 124, p &lt; .001, CFI = 0.92, TLI = 0.90, RMSEA = 0.08, SRMR = 0.05). The scale also demonstrated high reliability for each dimension: relationship with supervision (α = 0.90, ꞷ = 0.87), physical work space (α, ꞷ = 0.92), professional fulfillment (α, ꞷ = 0.88), and training and decision-making opportunities (α = 0.88, ꞷ = 0.84), with acceptable factor loadings (&gt;0.70). Conclusions: The adapted 18-item S20/23 scale is a valid and reliable tool for assessing job satisfaction among Peruvian nurses. The study highlights the importance of specific job satisfaction dimensions, such as relationships with supervisors and professional development opportunities, in the Peruvian nursing context.</p> Allison Ramirez-Cruz Caleb Sucapuca Mardel Morales García Víctor D Álvarez-Manrique Alcides Flores-Saenz Wilter C.

Traditional data privacy measures predominantly focus on anonymizing sensitive attributes and exact identifiers, leaving quasi-identifiers in their raw form, potentially exposing privacy vulnerabilities.<br />Objective: The primary objective of the presented work, is to anonymise the quasi-identifiers to enhance the overall data privacy preservation with minimal data utility degradation.<br />Methods: In this study, the authors propose the integration of ℓ-diversity data privacy algorithms with the OPTICS clustering technique and data correlation analysis to anonymize the quasi-identifiers.<br />Results: To assess its efficacy, the proposed approach is rigorously compared against benchmark algorithms. The datasets used are - Adult dataset and Heart Disease Dataset from the UCI machine learning repository. The comparative metrics are - Relative Distance, Information Loss, KL Divergence and Execution Time.<br />Conclusion: The comparative performance evaluation of the proposed methodology demonstrates its superiority over established benchmark techniques, positioning it as a promising solution for the requisite data privacy-preserving model. Moreover, this analysis underscores the imperative of integrating artificial intelligence (AI) methodologies into data privacy paradigms, emphasizing the necessity of such approaches in contemporary research and application domains.</p> Sreemoyee Biswas Vrashti Nagar Nilay Khare Priyank Jain Pragati Agrawal Copyright (c) 2024 Sreemoyee Biswas, Vrashti Nagar, Nilay Khare, Priyank Jain, Pragati Agrawal https://creativecommons.org/licenses/by/4.0 2024-05-17 2024-05-17 3 287 287 10.56294/dm2024287 Applicable methodologies for business continuity management in IT services: A systematic literature review https://dm.saludcyt.ar/index.php/dm/article/view/182 <p>Introduction: Currently, information technologies have one characteristic in common: their volatility. This is why it is important that companies have methodologies that allow adequate management of the continuity of the services offered through them.<br />Objective: In this sense, the purpose of this systematic literature review is to identify the most appropriate methodologies that can be implemented in companies to deal with these unforeseen interruptions.<br />Method: With a study based on a PICO question, the search for relevant literature in a scientific database was proposed using a search equation based on keywords.<br />Results: The studies offer qualitative results that mainly allow reducing response times before incidents of unforeseen interruptions, among the most notable is that the proposed systems help increase the success rate of recovery procedures by 80%, allow identifying and apply integration technologies that allow improving business continuity systems, among others. However, there is a knowledge gap for which the implementation of these methods is suggested for future proposals in order to achieve quantitative results that can be presented through metrics.<br />Conclusions: In conclusion, the present systematic literature review carried out the analysis and a comparison of the methodologies proposed by the authors and analyzes the results achieved in each of them, suggesting that 69% of the articles mention an origin of the associated interruptions to logical failures, 75% of the studies indicate that business continuity plans mostly have a preventive focus and 44% suggest continuous testing of plans to ensure their effectiveness.</p> Renzo Huapaya-Ruiz Brian Meneses-Claudio Copyright (c) 2024 Renzo Huapaya-Ruiz, Brian Meneses-Claudio https://creativecommons.org/licenses/by/4.0 2024-01-08 2024-01-08 3 182 182 10.56294/dm2024182 Validation of an Organizational Climate Scale in health workers https://dm.saludcyt.ar/index.php/dm/article/view/257 <p>Introduction: Organizational climate is a key factor in employee performance and satisfaction. In this study, the validity and reliability of an organizational climate scale in agroindustrial companies in Peru was examined. Objective: To analyze the psychometric properties of an organizational climate scale adapted to Peruvian Spanish. Methods: A methodological study was carried out. Demographic data were collected, as well as responses to an organizational climate questionnaire. Results: The data were analyzed using confirmatory factorial analysis (CFA). The reliability of the instrument was high (α = 0.92). However, the factor loadings of several items were not adequate, so a unidimensional model was tested, then a model with adequate factor loadings, and finally an optimal model. In this last 9-item model, the fit was optimal, and the factor loading was adequate for all items. Conclusion: Overall, the organizational climate scale demonstrated good reliability and validity in this context of agroindustrial companies in Peru. However, some items needed to be revised to improve the scale's accuracy. These findings provide a valuable tool for measuring the organizational climate in these types of companies and pave the way for future research in this field.</p> Flor Damiano-Aulla Jeydi Raqui-Rojas Víctor D.

A non-experimental, quantitative methodology was employed, gathering data via standardized surveys such as the DigCompEdu Check-In and RED TIC. The participant group comprised 120 teachers, whose responses were analyzed using logistic regression in SPSS v27. Descriptive findings indicated that 55.6% of the teachers demonstrated a high level of professional commitment, and 58.9% showed proficient digital pedagogical skills. Inferential analysis showed a significant correlation between digital competencies and technostress, with a Nagelkerke index of 0.622, suggesting that about 62.2% of the variation in technostress could be explained by differences in digital competencies. The study concludes that enhancing digital competencies among teachers could substantially reduce their technostress, emphasizing the need to effectively integrate these skills into teaching practices to improve the educational experience in virtual settings.</p> Karina Raquel Bartra-Rivero Lida Vásquez-Pajuelo Geraldine Amelia Avila-Sánchez Elba María Andrade-Díaz Gliria Susana Méndez-Ilizarbe Jhonny Richard Rodriguez-Barboza Yvonne Jacqueline Alarcón-Villalobos Copyright (c) 2024 Karina Raquel Bartra-Rivero, Lida Vásquez-Pajuelo, Geraldine Amelia Avila-Sánchez, Elba María Andrade-Díaz, Gliria Susana Méndez-Ilizarbe, Jhonny Richard Rodriguez-Barboza , Yvonne Jacqueline Alarcón-Villalobos https://creativecommons.org/licenses/by/4.0 2024-04-30 2024-04-30 3 303 303 10.56294/dm2024303 Bibliometric Mapping of Trends of Project-Based Learning with Augmented Reality on Communication Ability of Children with Special Needs (Autism) https://dm.saludcyt.ar/index.php/dm/article/view/261 <p>This study aims to analyze the use of project-based learning with augmented reality (AR) on the communication skills of autistic children through systematic literature review and theoretical bibliometric analysis of research on autistic children's communication skills sourced from Scopus from 2013 to 2022. The research method is a systematic literature review with analysis theory and bibliometric analysis with VOSviewer and RStudio applications. This research was conducted in several stages, namely determining i) research questions; ii) inclusion and exclusion criteria; iii) quality assessment; iv) data collection; and v) bibliometric analysis. The results of this study note that research on the communication skills of autistic children is still a research trend that is of great interest to researchers with an increase in research occurring from 2015 to 2022. Countries from the Americas and Asia have contributed the most to research on the communication skills of autistic children. The subject areas of psychology and social science are the subject areas with the most contributions, namely 22% each of the 165 articles found. There is a relationship between the term project (P), communication skills (CS), and autism spectrum disorder (ASD). This relationship is shown by the link strength P→CS is 2 and the link strength CS→ASD is 4. The characteristic requirements for autistic children for project-based learning with AR are middle class autistic children. The characteristics possessed by project-based learning can help in training the level of communication skills of autistic children and it would be better if assisted with the use of AR.</p> Dwi Fitria Al Husaeni M.
