Geographic Disparities in Hospice Quality and Family Caregiver Experience: The Roles of Ownership, Social Vulnerability, and Workforce Capacity
Jinho Cha, Misun Roh
Hospice quality should be interpreted in relation to both provider organization and the local conditions under which care is delivered. This study develops a provider-county perfor…
Inverse Behavioral Optimization of QALY-Based Incentive Systems Quantifying the System Impact of Adaptive Health Programs
Jinho Cha, Justin Yu, Junyeol Ryu +2
This study introduces an inverse behavioral optimization framework that integrates QALY-based health outcomes, ROI-driven incentives, and adaptive behavioral learning to quantify h…
Curriculum Learning with Synthetic Data for Enhanced Pulmonary Nodule Detection in Chest Radiographs
Pranav Sambhu, Om Guin, Madhav Sambhu +1
This study evaluates whether integrating curriculum learning with diffusion-based synthetic augmentation can enhance the detection of difficult pulmonary nodules in chest radiograp…
Mechanism design and equilibrium analysis of smart contract-mediated resource allocation
Jinho Cha, Justin Yu, Eunchan Daniel Cha +4
Decentralized coordination and digital contracting are becoming essential in complex industrial systems, yet existing approaches often rely on ad-hoc heuristics or purely technical…
FOSSIL: Regret-Minimizing Curriculum Learning for Metadata-Free and Low-Data Mpox Diagnosis
Sahng-Min Han, Minjae Kim, Jinho Cha +4
Deep learning in small and imbalanced biomedical datasets remains fundamentally constrained by unstable optimization and poor generalization. We present the first biomedical implem…
Doubly Robust Estimation with Stabilized Weights for Binary Proximal Outcomes in Micro-Randomized Trials
Jinho Cha, Eunchan Cha
Micro-randomized trials (MRTs) are increasingly used to evaluate mobile health interventions with binary proximal outcomes. Standard inverse probability weighting (IPW) estimators…
Modeling ROI in chronic disease management: a simulation-based framework integrating patient adherence and policy timing
Jinho Cha, Eunchan D. Cha, Eunchan Daniel Cha +3
Background: Chronic diseases impose a sustained burden on healthcare systems through progressive deterioration and long-term costs. Although adherence-enhancing interventions are w…
