Article Synopsis
- Flight accidents triggered by spatial disorientation (SD) pose significant risks to aviation safety, yet research on this issue is limited.
- An experiment involving 10 pilots and 10 non-pilots aimed to evaluate SD by inducing it through video stimuli, gathering subjective feedback and center of foot pressure (CoP) data.
- Results showed pilots experienced fewer self-reported SD events compared to non-pilots, and their CoP variability was significantly lower, highlighting their better ability to recognize and manage SD, which could help decrease flight-related accidents.
This paper employs low-field nuclear magnetic resonance (LF-NMR) technology to meticulously analyze and explore the intricate soybean infiltration process. The methodology involves immersing soybeans in distilled water, with periodic implementation of Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence experiments conducted at intervals of 20 to 30 minutes to determine the relaxation time T2. Currently, magnetic resonance imaging (MRI) is conducted every 30 minutes.

Background: Spatial disorientation (SD) is a problem that pilots often encounter during a flight. One reason for this problem is that among the three types of SD, there is no validated method to detect the Type I (unrecognized) SD.
Objective: In this pursuit, initially we reviewed the problems and the evaluation methods of associated with SD.
Design of automatic urine collection system for medical system applications.

Background: The results of urine tests are often affected by improper midstream urine collection time, urine spilling, and urine pollution, all of which can lead to an increase in the test error.
Objective: To solve this problem, aiming at improving the toilet environment at the hospitals and public physical examination centers, this paper designs an automatic urine collection system. It can automatically adjust the position of the urine cup with an infrared remote controller, or manually, adjust the position of the urine cup in special situations according to the needs of the user.
