An Application of the Grid-Based Two-Step Floating Catchment Area Method to Assess the Spatial Accessibility of Green Spaces in Seoul, South Korea
The conventional Two-Step Floating Catchment Area (2SFCA) method treats large-scale facilities as single centroids, leading to systematic under- and overestimation of spatial accessibility measures. To address this limitation, this study proposes a Grid-based G2SFCA methodology that disaggregates supply facilities into grid cells to better capture their shape and assigns them as multiple access points. Using green spaces in Seoul, South Korea, as…
Customized decision-making support per location's characteristics of spatial accessibility: A case study of emergency healthcare in New York City
Locations can be classified based on the different characteristics (the combination of temporal changes and different levels) of their accessibility. • These clusters can identify diverse needs across locations to effectively reduce access inequality. • Our work can facilitate the optimal resource allocation and support customized and flexible policy responses
An Areal Approach to Spatial Accessibility Analysis
Place‐based spatial accessibility quantifies the distribution of access to goods and services across space. The Two‐Step Floating Catchment Area (2SFCA) family of methods have become a default tool for spatial accessibility analysis in part due to their intuitive approach and interpretability. This family of methods relies on calculating catchment areas around supply locations to estimate the area and population that may utilize them. However, th…
Parental Intention for Health Promotion in Children with Disabilities: Extending the Theory of Planned Behavior with Parenting Stress
Background/Objectives : This study applies an Extended Theory of Planned Behavior, integrating parenting stress to examine factors influencing parental intentions to participate in health promotion programs for children with disabilities. Methods : Data ( n = 345) were collected and analyzed using Structural Equation Modeling. Results : Results indicated that parenting stress affects intention indirectly through subjective norms and perceived beh…
Ending the HIV Epidemic: Development and Evaluation of CyberGIS-HIV, a Web-Based Prediction Application
Officials from US state and county health departments perceive the need to adopt new methods for making epidemiological decisions about HIV. Hence, a web-based prediction modeling application, CyberGIS-HIV, was developed and systematically compared with currently used approaches (e.g., community consultation) in a sample of 42 state and federal public health officials as well as senior and junior modelers. Overall, CyberGIS-HIV had more favorable…
Evaluating the impacts of supply-demand dynamics and distance decay effects on public transit project assessment: A study of healthcare accessibility and inequalities
Exploring Spatial Mismatch between Primary Care and Older Populations in an Aging Country: A Case Study of South Korea
With the rapid growth of aging populations in South Korea, it is important to assess spatial accessibility to healthcare resources as older adults may need frequent visits to hospitals. Healthcare spatial accessibility is measured based on available resources (e.g., physicians, beds, services), demands (e.g., population), and travel costs (e.g., distance or time). In this study, we employed an Enhanced Two-Step Floating Catchment Area (E2SFCA) me…
Daily changes in spatial accessibility to ICU beds and their relationship with the case-fatality ratio of Covid-19 in the state of Texas, USA
An Examination of the Stochastic Distribution of Spatial Accessibility to Intensive Care Unit Beds during the Covid ‐19 Pandemic: A Case Study of the Greater Houston Area of Texas
Sufficient and reliable health care access is necessary for people to be able to maintain good health. Hence, investigating the uncertainty embedded in the temporal changes of inputs would be beneficial for understanding their impact on spatial accessibility. However, previous studies are limited to implementing only the uncertainty of mobility, while health care resource availability is a significant concern during the coronavirus disease (COVID…
A Preliminary Study on the Loss of Iron and Arsenic in the Re-Melting of Iron-Bearing Arsenical Copper: Loss of iron and arsenic in re-melting of iron-bearing arsenical copper
Re-melting experiments were conducted with specimens made of high-arsenic copper alloys containing lead, iron and sulphur. The melting treatment at 1000°C in ambient conditions for 5 min was found to cause an almost complete removal of iron and sulphur along with a notable reduction of arsenic levels. Evidence was found that the preferential oxidation of iron and arsenic was responsible for this change in composition. The treatment also brought a…
