This research focuses on the development of a foot-worn device to assist individuals with limited mobility in walking. The device aims to reduce the risk of accidents by closely moni-toring the wearer's movements and detecting potential hazards. It incorporates sensors, in-cluding the MPU6050 gyro sensor and KY-031 vibration sensor, to track the wearer's walking behavior. In case of abnormalities, such as falls, the device triggers an auditory alert and noti-fies the caregiver via LINE Notify. The system is controlled by the Node MCU ESP8266, enabling seamless integration with the Internet of Things (IoT). The objective of this study is to design an IoT system for medical assistance. The researchers created a prototype of a smart ankle device capable of detecting falls and sending notifications to the user's smartphone. The effectiveness of the notification system was evaluated using the Line Notify application. Re-sults demonstrated a successful detection of falls in 48 out of 50 trials, with two instances of false alarms during normal walking. The overall efficiency of the smart ankle device was 98%. In summary, the proposed smart ankle device demonstrates promising potential for var-ious applications in fall detection and safety alert systems. Further improvements and collab-orations with healthcare experts are recommended to enhance its performance and make it commercially viable. The device's connectivity and responsiveness to IoT systems are vital aspects to be considered. Future research should aim to develop additional features in collab-oration with physiotherapists and healthcare professionals to meet user requirements. The de-vice holds significant benefits in terms of fall detection and safety alerts, and efforts should be made to enhance its durability, robustness, and commercialization prospects.

Fatal motorcycle accidents on- and off-road continue to be overlooked in the literature. Research is scant on morbidity and mortality due to neck injury, which leaves patients and their families debilitated chronically. Great Lakes EMS Inc. conducted a 10-year retrospective case study, which highlighted that motocross riders who do not wear a neck brace are at an 89% higher risk of a critical cervical spine injury; highly unstable cervical spinal fractures have a sustainably higher risk of morbidity and mortality. Proposed mechanisms of motocross neck braces displace the forces on the neck onto the helmet of the rider to provide a smooth distribution of forces, whereas lack of neck brace use places riders at risk for upper cervical spine fractures such as Jefferson fractures, Hangman's fractures, and Odontoid fractures. Further, evidence suggests the use of back protectors may increase the risk of thoracic and upper spine injuries during a motorcycle crash. The limited data on this topic continues to be a challenge, as there is a lack of understanding of the nature of these injuries, which are likely preventable with proper neck protection.

Background: Adolescent Idiopathic Scoliosis (AIS) patients have been found to exhibit cortical asymmetry. This study aimed to examine the impact of conservative treatments on perceptual and cognitive asymmetry in the auditory system of AIS patients with thoracic major curve. Method: The study involved 30 AIS patients and 21 healthy subjects. The intervention group used a Cheneau brace and performed 18 Schroth Best Practice (SBP) exercise sessions. Auditory lateralization was assessed with a Dichotic Listening Paradigm (DLP) in both groups before and after the intervention. Results: The six-week intervention resulted in a significant increase in left ear responses in the force-left condition in the AIS (p<0.05). Left ear responses were lower in AIS at baseline (p<0.05). Sixth-week results were similar in all conditions (p>0.05). Conclusion: The results of this study demonstrated that SBP exercises and Cheneau brace treatment can improve perceptual and cognitive asymmetry in the auditory system in AIS patients with thoracic major curve. Scoliosis-associated changes in the spine and postural control may affect auditory perception by causing adaptations in sensory and motor networks. Future studies are needed to examine the connectivity in brain regions related to motor control and auditory processing after conservative treatment.

To solve the problem of complex sensor installation and easy damage in contact displacement measurement, a non-contact measurement method of brace displacement in bridge swivel construction based on binocular vision is proposed in this study. Combined with monitoring data in a swivel construction interchange project, binocular vision system was compared and analyzed with the traditional displacement meter and total station. Results showed that force versus displacement variation plots were obtained by binocular visual measurement in the weighing test, the inflection point can be clearly distinguished, and the position of the inflection point was the same as that of the displacement meter; monitoring data of binocular vision measurement and total station were compared and analyzed in the bridge swivel process, the average error was no more than 0.18 mm, the maximum error was no more than 0.42 mm, and the standard deviation was no more than 0.12. The method proposed in this study can be used as an alternative to displacement meter and total station measurement methods in bridge swivel construction, the problem of complex sensor installation and easy damage is solved in brace displacement measurement, equipment and labor costs can be effectively saved.

A high-voltage transmission tower consists of structures to avoid the risk of electric shock and to prevent the risk of collapse. Hence, towers are generally designed to be high-rise for efficiency. The main posts of the tower are primary structural members that resist loads under various load conditions. Therefore, the contribution of the secondary member to securing the stiffness and strength of the main posts by reducing the effective buckling length is important. However, there are no detailed design criteria for secondary members. In this study, the structural effects of horizontal members and braces on the torsional stiffness, elastic buckling strength, and load-carrying capacity of transmission towers were observed through various structural analysis methods including linear-elastic, eigenvalue, and geometric nonlinear and inelastic analyses under governing load combinations. According to the analytical study, rather than the horizontal members, the brace spacing significantly affects the structural performance. Therefore, the number of horizontal members can be minimized if sufficient brace members are erected. If the brace spacing is wide, it is recommended that the horizontal members be erected to create K bracing, and the buckling resistance of the main posts can be thus enhanced.
