Noise pollution includes undesired sounds that lead to negative physiological and psychological outcomes in individuals. Areas with a unique ergonomic design when compared to other work environments, such as ships, are risky. Identification and limitation or minimization of the impact of noise pollution in ships would directly affect crew health and maximum efficiency of the operation of the systems. Thus, the exposure of the ship crew to noise pollution was measured in the current study. Furthermore, the measurements conducted on the ships were compared to the International Maritime Organization (IMO) A.468 (XII) international standards. In the study, noise measurements were conducted with 72 crew members who met certain criteria in nine ships with different properties to determine noise pollution in these ship environments and the exposure of the crew. The current study analyzed the effects of ship-borne noise pollution on the crew and certain solutions were proposed.

Hypertrophic cardiomyopathy (HCM), including obstructive HCM and non-obstructive HCM, can lead to sudden cardiac arrest in adolescents and athletes. Early diagnosis and treatment through auscultation of different types of HCM can prevent the occurrence of malignant events. However, it is challenging to distinguish the pathological information of HCM related to differential left ventricular outflow tract pressure gradients.

Metal-oxide thin-film semiconductors have been highlighted as next-generation space semiconductors owing to their excellent radiation hardness based on their dimensional advantages of very low thickness and insensitivity to crystal structure. However, thin-film transistors (TFTs) do not exhibit intrinsic radiation hardness owing to the chemical reactions at the interface exposed to ambient air. In this study, significantly enhanced radiation hardness of AlO-passivated ZnO TFTs against high-energy protons with energies of up to 100 MeV is obtained owing to the passivation layer blocking interactions with external reactants, thereby maintaining the chemical stability of the thin-film semiconductor.

Introduction: High occupational stress is generally associated with poorer mental health and reduced performance in military personnel, whereas access to support resources is associated with positive outcomes. However, little research has examined the unique stressors and supports experienced by sailors on ships while underway at sea. The objectives of this study were to (1) identify sailors' underway stressors and supports and (2) examine how these differ as a function of demographic and operational factors.

The screening of chemical libraries is an essential starting point in the drug discovery process. While some researchers desire a more thorough screening of drug targets against a narrower scope of molecules, it is not uncommon for diverse screening sets to be favored during the early stages of drug discovery. However, a cost burden is associated with the screening of molecules, with potential drawbacks if particular areas of chemical space are needlessly overrepresented.

A novel all-fiber optic current sensor (FOCS) is designed specifically for the measurement of large transient currents based on the Faraday effect. A reciprocal symmetric structure is incorporated into the optical sensing loop, and the current dependent phase demodulation is achieved by using a passive optical fiber coupler and the homodyne detection scheme. This design offers several advantages, including structural simplicity, high voltage insulation, low noise, high linearity, and excellent frequency response, and is highly suitable for use in any system of high-voltage, high-power, and high-frequency in nature.
