The Impact of Port Total Factor Productivity on Carbon Dioxide Emissions in Port Cities: Evidence from the Yangtze River Ports
Autor: Xingong Ding, Yong-Jae Choi
Publikováno v: Applied Sciences, Vol 14, Iss 6, p 2406 (2024)
This paper investigates the relationship between port productivity and carbon dioxide (CO2) emissions in port cities. The study initially employs the global Malmquist productivity index (MPI) to measure productivity growth in 16 major inland ports al

A model of COVID-19 pandemic with vaccines and mutant viruses.
Autor: Young Rock Kim, Yong-Jae Choi, Youngho Min
Publikováno v: PLoS ONE, Vol 17, Iss 10, p e0275851 (2022)
This paper proposes a compartment model (SVEIHRM model) based on a system of ordinary differential equations to simulate the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Emergence of mutant viruses gave rise to multiple pe

Electrochemical Properties of Silver Nanoparticle Doped Aminosilica Nanocomposite
Autor: Yong-Jae Choi, Tzy-Jiun M. Luo
Publikováno v: International Journal of Electrochemistry, Vol 2011 (2011)
The electrochemical properties of silver nanoparticle (d∼ 5 nm) synthesized within aminosilica film from spontaneous reduction reaction were examined using cyclic voltammetry and the results show that the nanocomposite film exhibits similar redox p
