Application of Machine Learning Algorithms for Geogenic Radon Potential Mapping in Danyang-Gun, South Korea

open access: yesFrontiers in Environmental Science, 2021
Continuous generation of radon gas by soil and rocks rich in components of the uranium chain, along with prolonged inhalation of radon progeny in enclosed spaces, can lead to severe respiratory diseases.

On the setting of environmental noise and the performance of population dynamical models [PDF]

open access: yes, 2010
Background: Environmental noise is ubiquitous in population growth processes, with a well acknowledged potential to affect populations regardless of their sizes. It therefore deserves consideration in population dynamics modelling.

Pro-inflammatory effects of crystalline- and nano-sized non-crystalline silica particles in a 3D alveolar model

open access: yesParticle and Fibre Toxicology, 2020
Background Silica nanoparticles (SiNPs) are among the most widely manufactured and used nanoparticles. Concerns about potential health effects of SiNPs have therefore risen. Using a 3D tri-culture model of the alveolar lung barrier we examined effects of

A Strain Rate-Dependent Damage Evolution Model for Concrete Based on Experimental Results

open access: yesAdvances in Civil Engineering, 2021
There are various definitions of damage variables from the existing damage models. The calculated damage value by the current methods still could not well correspond to the actual damage value.

Soundscapes and environmental noise management

open access: yes, 2010
Despite the current expansion of interest in soundscapes, the roles and application of the concept, vis-୶is that of environmental noise management, have not been adequately articulated. Soundscapes and environmental noise management are complementary,

Nationwide distribution and factors related to indoor fine particulate matter concentrations in subway stations in Korea: Results of first-year measurement

open access: yesEnvironment International
This study assessed the seasonal distribution and factors associated with PM2.5 in nationwide subway stations in Korea. A total of 229,644 data points collected over one year were used to determine one-day PM2.5 concentrations from 642 subway stations ...

Quantitative Evaluation for Reinforcement Effect of Auxiliary Steel Beams Based on Running Safety and Dynamic Response

open access: yesShock and Vibration, 2021
Aiming at the existing heavy-haul railway, bridges hardly meet the transportation requirements. Based on the spatial vibration calculation model of the freight train–track–bridge (FTTB) system, the FTTB spatial vibration model under the condition of ...

Investigation and modeling of transport noise dependence on traffic speed and impact on population annoyance

open access: yesJournal of Environmental Engineering and Landscape Management, 2022
Transport noise is a serious problem in cities and has a negative impact on both health and economics. In addition to the aforementioned unnoticed health effects, traffic noise has also been identified as one of the leading causes of sleep disorders ...
