Vol. 7 No. 1 (2024): Journal of Advances in Military Studies

The April 2024 issue of the Journal of Advances in Military Studies (JAMS) published three studies.     Ra et al.(2024) explored the importance of improving PPG measurement accuracy in military smartwatches used by soldiers. It highlighted factors like physical condition and environmental influences that contributed to errors. Accurate health data is crucial for soldier safety and operational performance during intense activities, emphasizing the need for enhanced wearable technology.     Kim and Lee (2024) examined the use of 4th Industrial Revolution technologies like AI, IoT, and big data for smart underground ammunition depots. It prioritized factors such as safety and logistics through AHP analysis, emphasizing the need for strengthened safety systems and efficient monitoring.     Nam et al. (2024) investigated the effect of hair and beards on gas mask airtightness, using a SMARTMAN mannequin for testing. Results showed that the presence of hair and beards reduces the mask's effectiveness, with optimal sizing being crucial for maintaining airtightness. These findings contributed to improving gas mask performance and military readiness against chemical and biological threats.
