About the Lab
Professor Hyojin Han's research lab focuses on health economics and public policy, particularly examining the socioeconomic impacts of healthcare reforms such as the Affordable Care Act's dependent mandate. The lab also investigates urban population dynamics and behavioral responses to public health interventions, especially during the COVID-19 pandemic. Additionally, the lab explores advanced oxide materials, including double perovskites like Ba₂FeMoO₆, for their magnetic and transport properties at room temperature. These diverse research directions reflect a strong interdisciplinary approach combining social science, public health, and materials science.

4The Affordable Care Act Dependent Mandate (ACA-DM) has increased young adults’ health insurance coverage through parents’ employer-sponsored health insurance. This could have increased employers’ labor costs and thus reduced parents’ wages. In this study, we examine the effects of the ACA-DM on family income and medical spending. Using a difference-in-differences approach, we find evidence that the ACA-DM decreased family income but did not increase young adults’ medical spending. The results im
Summary form only given. Ba/sub 2/FeMoO/sub 6/ (BFMO) shows room temperature magnetoresistance (MR) and ferrimagnetic phase transition with T/sub c//spl sim/320-340 K. This compound has an ordered double perovskite structure, in which the Fe and Mo ions are arranged alternatively with ideal saturation moment of 4 /spl mu//sub B//f.u. Low-field MR in BFMO can be explained by intergrain tunneling due to spin dependent scattering at the grain boundary and the degree of ordering.
본 연구는 COVID-19로 인한 사회적 거리두기 정책이 서울의 시간대별, 연령대별 생활인구 패턴에 미치는 영향을 분석했다. 분석 결과, 시간대별 생활인구 감소 효과는 야간보다 주간이 크게 나타났으며, 연령대별은 젊은 세 대가 다른 연령대에 비해 큰 것으로 나타났다. 사회적 거리두기 정책은 연령대별로 서울시 생활인구 이동패턴에 미치 는 영향에 차이가 나타났다. 구체적으로 청년층에서는 5인 이상 모임 금지와 영업시간 제한이 가장 큰 감소 효과를 보였고, 중장년층에서는 재택근무와 지하철 운행 단축이 가장 큰 감소 효과를 보였다. 이를 통해 시간대와 연령대를 고려한 구체적인 방안으로 추진되어야 함을 확인하였다. 특히 주간시간대를 중심으로 방역대책을 강화할 필요가 있 으며, 야간시간대 생활인구 감소 효과가 미미해 이를 보완하는 대책이 필요한 것으로 판단된다.
