The reliability of medical Internet of Things (IoT) systems is critically dependent on network resilience, particularly in indoor hospital environments where conventional Wi-Fi infrastructures are vulnerable to single points of failure. Although ESP-Mesh has emerged as a promising self-healing communication protocol, its performance characteristics in medical IoT monitoring contexts remain insufficiently explored. This study aims to experimentally characterize the performance of ESP-Mesh networks for resilient medical IoT monitoring systems by analyzing multi-hop latency behavior, signal degradation, and communication stability under indoor medical-like conditions. A multi-parameter monitoring prototype integrating infusion volume, drip rate, and heart rate sensors was deployed as an experimental platform. Network performance was evaluated through controlled measurements of RSSI, end-to-end latency, and self-healing behavior, while MQTT was employed to assess cloud-based transmission efficiency. The results demonstrate that ESP-Mesh maintains stable self-healing communication with an average multi-hop latency of 0.714 s across distances up to 5 m, with latency increasing consistently as RSSI decreases. MQTT cloud transmission achieved a lower average latency of 0.247 s with zero packet loss, confirming its suitability for lightweight medical data delivery. Sensor evaluation revealed high accuracy for infusion volume monitoring (95.42%), while heart rate and drip rate measurements exhibited lower reliability due to signal interference and environmental sensitivity. These findings provide empirical insights into the performance limits and trade-offs of ESP-Mesh networks in medical IoT environments. The study confirms the feasibility of ESP-Mesh as a resilient communication backbone for medical monitoring, while highlighting the necessity of advanced signal processing to achieve clinical-grade sensing reliability.

Abstract: The development of digital technology has driven the transformation of educational services through the implementation of data-based learning systems and smart devices. One of the emerging approaches is the use of the Internet of Things (IoT) in building smart classrooms, which are classrooms capable of integrating physical devices, sensors, and information systems to improve learning efficiency and learning environment management. This study aims to analyze the implementation of IoT in the formation of smart classrooms, covering aspects of system design, device integration, and evaluation of its effectiveness in supporting the teaching and learning process. The research method used is a quantitative and experimental approach, by designing an IoT-based smart classroom prototype that integrates temperature, humidity, light intensity, and presence detection sensors, as well as device control such as lights, air conditioning, and projectors through an automatic system and remote control. Data was collected through device performance measurements, network stability tests, and questionnaires distributed to users (teachers and students) to assess the system's ease of use and usefulness. The results showed that the implementation of IoT in classrooms can improve the efficiency of facility management through device automation, facilitate real-time monitoring of classroom conditions, and provide a more comfortable and responsive learning environment. In addition, the developed system demonstrated stable data communication performance with low latency within acceptable operational limits. These findings indicate that the application of IoT in smart classrooms has the potential to contribute significantly to improving the quality of learning and classroom management, particularly in supporting a technology-based education ecosystem. This study recommends further development in the areas of data security, device interoperability, and integration with Learning Management Systems (LMS) to strengthen the sustainable implementation of smart classrooms.

The digital transformation of manufacturing companies has gained momentum, particularly through the implementation of Enterprise Resource Planning (ERP) systems. ERP systems are integrated software platforms that streamline core business functions, including finance, human resources, procurement, and production. These systems significantly improve operational efficiency, reduce costs, and enhance decision-making capabilities within manufacturing firms. The centralization of data and automation of routine tasks eliminate data silos and manual errors, leading to better coordination, real-time insights, and optimized resource allocation. However, ERP adoption comes with challenges, such as resistance to change, the complexity of system integration, and customization costs. Despite these hurdles, the long-term benefits, such as cost savings, improved collaboration, and enhanced customer relationship management, outweigh the initial investments. As ERP systems evolve with emerging technologies like artificial intelligence (AI) and the Internet of Things (IoT), they offer even more advanced capabilities in predictive maintenance, real-time monitoring, and automated decision-making. This paper concludes that ERP systems are crucial for the digital transformation of manufacturing companies, helping them become more agile, cost-efficient, and competitive in an increasingly digital world.

Advances in Natural Language Processing (NLP) in education have led to the development of decision support systems capable of processing textual data such as student essay responses, learning feedback, academic records, and evaluation documents. However, most previous research has focused on improving model accuracy, while aspects of trust, transparency, fairness, and human involvement in decision validation have not been a primary focus. This research aims to develop a framework for Trustworthy NLP Systems for Educational Decision Support based on a Human-Centered Artificial Intelligence approach that positions teachers, students, and educational policymakers as key actors in the system’s design, interpretation, and evaluation processes. The novelty of this research lies in the integration of four key dimensions explainability, fairness, reliability, and human oversight into the NLP system architecture to support more ethical, transparent, and accountable educational decisions. The research methodology employs an experimental approach involving stages of educational text data collection, data preprocessing, text representation, NLP-based modeling, model performance evaluation, and system trust analysis through Explainable AI and fairness evaluation. The developed system is not only designed to generate educational classifications or recommendations but also to provide explanations for the model’s decision-making basis, thereby enabling human verification. The expected outcome is the creation of a conceptual and technical NLP model capable of improving the quality of educational decision-making without compromising ethical principles, accountability, and user-centricity. This research contributes to strengthening the direction of educational NLP development that is not only computationally intelligent but also trustworthy, inclusive, and human-centered.
