De Facto population density and the location of AEDs: Are they proportional to each other?

Is the spatial distribution of AEDs proportional to the static population or the De Facto population? The purpose of this study is to investigate the correlation between the distribution of automated external defibrillators (AED) installed in public spaces and the population density in Seoul. Unlike the past, when the residential population could only be measuredContinue reading “De Facto population density and the location of AEDs: Are they proportional to each other?”

Analysis of Changes in the Number of Subway Passengers during the COVID-19 Pandemic Using the K-shape Clustering Algorithm

Since the first confirmed case of COVID-19 in South Korean in January 2020, there has been a great deal of fear and anxiety around the possibility of COVID-19 transmission when using public transportation, such as subways. In this study, I used the K-shape clustering algorithm to determine how public transportation users’ ridership changed in responseContinue reading “Analysis of Changes in the Number of Subway Passengers during the COVID-19 Pandemic Using the K-shape Clustering Algorithm”
