A Differential Equation Model for the Dynamics of Youth Gambling
Tae Sug Do, Young S. Lee
Osong Public Health Res Perspect. 2014;5(4):233-241.   Published online August 31, 2014
Objectives We examine the dynamics of gambling among young people aged 16–24 years, how prevalence rates of at-risk gambling and problem gambling change as adolescents enter young adulthood, and prevention and control strategies. Methods A simple epidemiological model is created using ordinary nonlinear differential equations, and a threshold condition that spreads gambling is identified through stability analysis. We estimate all the model parameters...
Role of Active and Inactive Cytotoxic Immune Response in Human Immunodeficiency Virus Dynamics
Hernan Dario Toro Zapata, Angelica Graciela Caicedo Casso, Derdei Bichara, Sunmi Lee
Osong Public Health Res Perspect. 2014;5(1):3-8.   Published online February 28, 2014
Objectives Mathematical models can be helpful to understand the complex dynamics of human immunodeficiency virus infection within a host. Most of work has studied the interactions of host responses and virus in the presence of active cytotoxic immune cells, which decay to zero when there is no virus. However, recent research highlights that cytotoxic immune cells can be inactive but never...
A Note on Obesity as Epidemic in Korea
Mun Seok Kim, Chaeshin Chu, Yongkuk Kim
Osong Public Health Res Perspect. 2011;2(2):135-140.   Published online June 30, 2011
Objective To analyze the incidence of obesity in adults aged 19–59 years in Korea and predict its trend in the future. Methods We considered a two-compartmental deterministic mathematical model Susceptible-Infected-Susceptible (SIS), a system of difference equations, to predict the evolution of obesity in the population and to propose strategies to reduce its incidence. Results The prevention strategy on normal-weight individuals produced a greater improvement than...
Mathematical Modeling of Vibrio vulnificus Infection in Korea and the Influence of Global Warming
Chaeshin Chu, Younghae Do, Yongkuk Kim, Yasuhisa Saito, Sun-Dong Lee, Haemo Park, Jong-Koo Lee
Osong Public Health Res Perspect. 2011;2(1):51-58.   Published online June 30, 2011
Objectives To investigate the possible link between Vibrio vulnificus population size in seawater and water temperature. Methods We collected incidence and water temperature data in coastal regions of Korea and constructed a mathematical model that consisted of three classes; susceptible fish, infected fish available to humans, and infected humans. Results We developed a mathematical model to connect V. vulnificus incidence with water temperature using estimated...
