Volume 5, Issue 5 - 3 Articles

This issue presents a collection of research addressing healthcare monitoring, mathematics education, and intelligent environmental sensing systems. The published papers examine the use of wearable acceleration sensors and time-series classification techniques for identifying walking balance and supporting fall-risk assessment, the hierarchical development of the triangle concept in mathematics education through the framework of geometric thinking levels, and an anomaly-detection-based early warning system for maritime storm formation using temporal autoencoders and meteorological sensor data. Collectively, these contributions highlight the growing role of intelligent sensing technologies, machine learning, educational analytics, and data-driven monitoring systems in improving healthcare outcomes, strengthening learning processes, and enhancing environmental awareness and operational safety in real-world applications.

Identification of Walking Balance using Acceleration Sensors
by Junyu Chen, Michiyuki Hirokane and Yukio Horiguchi
Journal of Engineering Research and Sciences, Volume 5, Issue 5, Page # 1-11, 2026; DOI: 10.55708/js0505001
Abstract: The risk of falling increases with age, affecting approximately one in three individuals over 65 and one in two over 80 annually. In Japan, the fall rate among older adults ranges from 8.5% to 25.3%, and falls are a major cause of fractures and long-term care needs. Balance impairment is one of the key factors… Read More

A Study on the Hierarchical Expansion of the Triangle Concept in Mathematics Education
by Hyeseong Kang and Eunsung Jekal
Journal of Engineering Research and Sciences, Volume 5, Issue 5, Page # 12-18, 2026; DOI: 10.55708/js0505002
Abstract: This study aims to analyze the hierarchical development of the triangle concept across elementary and secondary mathematics curricula through the theoretical lens of Van Hiele’s geometric thinking levels. The triangle is introduced in elementary school as a visual and perceptual object, reinterpreted in middle school as a structure involving relationships among sides and angles, and… Read More

Early Warning for Maritime Storm Formation Using Temporal Autoencoder-Based Anomaly Detection
by Snehashish Srivastava, Haiping Xu, Donghui Yan and Ramprasad Balasubramanian
Journal of Engineering Research and Sciences, Volume 5, Issue 5, Page # 19-39, 2026; DOI: 10.55708/js0505003
Abstract: Storms remain a serious hazard at sea, exposing vessels to rapidly changing conditions that endanger human life and result in substantial economic losses. Satellite-based detection methods are widely used but require significant computational resources and depend on land-to-sea communication links, which may become unreliable during severe weather. Machine learning approaches offer strong potential for early… Read More
