Modern challenges require effective methods for stress monitoring and management, which drive the implementation of innovative solutions. This article presents the development of a wearable device integrated with Internet of Things (IoT) technology, capable of detecting and quantitatively assessing stress levels in real-time. This technology enhances the accuracy of stress evaluation, enabling quick responses and the development of personalized stress management strategies. The device uses a Field-Programmable Gate Array (FPGA) as the main controller and includes nine sensors: Photo plethysmography (MAX30102), electroencephalography (EEG), electrocardiography (ECG), glucose level (GS), electromyography (EMG), temperature (TS), pressure (PS), heart rate (HRS), pulse (PS), and galvanic skin response (GSR). These sensors measure physiological parameters such as heart rate, skin conductance, and breathing rate, which are associated with stress. The collected data is transmitted via Wi-Fi to the Firebase platform. The article also discusses the benefits of IoT-enabled wearable devices, their versatility for use in various environments such as offices, educational institutions, and healthcare settings, where stress management plays a critical role. Continuous monitoring allows users to track stress levels and take timely actions to improve their well-being. Experimental data shows that the device achieves 85% accuracy in measuring heart rate and breathing. This device can be valuable in both everyday life and professional fields, including medicine, education, and work environments, where stress control is crucial for health and productivity).

The present study aims to unpack the university English as a foreign language (EFL) teachers' practices and attitudes towards intercultural approach (ICA) and identify the prospective EFL teachers' level of preparedness to implement ICA. For this purpose, 36 EFL teachers and 45 master students doing a program on TEFL (Teaching English as a Foreign Language) were chosen to collect data through a survey and project analysis. The research findings indicate that despite recognising the intercultural paradigm in teaching EFL, embedded in all Kazakhstani regulations and the increasing tendency to use authentic textbooks; there is a lack of sound preparedness to implement ICA for both pre-service and in-service EFL teachers. Furthermore, the results suggest that two-thirds (66.6%) of master students could not identify all intercultural attributes in the coursebook. In-service teachers' agreement level on the importance of ICA is high; however, they lack practical skills for nuanced integration of ICA in EFL classrooms. This article can serve as a discussion platform to tackle challenges associated with ICA implementation in higher education not only in Kazakhstan but in the international context, as this issue is topical for many countries in the world where English is taught as a foreign language.

This study aims to identify the most suitable IoT communication protocol for a digital twin architecture, focusing on meeting the demands of real-time data transmission with stability and security. The research methodology involves a comparative performance analysis of MQTT over TCP, MQTT over WebSocket, and HTTP protocols, evaluating their latency, connectivity stability, and IoT application feasibility using an ESP32 microcontroller and DHT22 sensor setup. The experimental results demonstrate that MQTT over TCP achieves the lowest average latency at 290.5 ms, while MQTT over WebSocket exhibits more stable latency profiles with a 193.2 ms standard deviation; HTTP, despite its broader compatibility, showed higher average latency of 342.6 ms with a 307.9 ms standard deviation. These findings provide valuable insights for digital twin implementations, enabling developers to make informed protocol selections based on specific requirements, whether prioritizing real-time performance through MQTT protocols or emphasizing system compatibility and simplicity through HTTP.
