Professor Juhwan Oh's research lab focuses on population health, with a strong emphasis on social determinants of health across the lifespan. The lab investigates health disparities related to socioeconomic status, family and peer influences, and employment insecurity, particularly in the context of public health crises like the COVID-19 pandemic and long-term developmental outcomes such as adolescent mental health and child growth. Research also extends to reproductive health and health behavior in low- and middle-income countries, especially Vietnam and South Korea, with policy-relevant interventions as a central goal.

In the first two months of the COVID-19 pandemic, the Republic of Korea (South Korea) had the second highest number of cases globally yet was able to dramatically lower the incidence of new cases and sustain a low mortality rate, making it a promising example of strong national response. We describe the main strategies undertaken and selected facilitators and challenges in order to identify transferable lessons for other countries working to control the spread and impact of COVID-19. Identified
The adolescent depression experience is not only an individual phenomenon but is highly associated with other factors such as parents, peers, academic achievement, and even gender mix in the school. Thus, prevention measures on youth depression need to focus on emphasizing less pressure from parents on academic performance, and establishing healthy inter-gender relationships within co-education schools.
Household wealth in early life matters for physical growth with conditions of poverty and deprivation influencing growth faltering even beyond the 1,000 days window. The influences of early childhood poverty, so prevalent among children in low- and middle-income countries, must be addressed by policies and programs targeting early life but also focusing on older children experiencing growth faltering.
Precarious workers were more likely to be smokers and heavy smokers than standard workers. Unemployment is also a significant risk factor for decreased quitting and smoking relapse. However, insecure employment was an even more consistent determinant of current smoking behavior than unemployment.
The study results call for health and education policies to encourage the postponement of early sexual activity in young Vietnamese women as protection against risky sexual behaviour later in life.
The proportion of women in Vietnam using modern contraceptive methods has remained relatively high in recent years with significant variation across Vietnam's 63 provinces. Women of lower SES are more likely to use modern contraceptive methods, especially in the poorer provinces. Achieving access to universal reproductive health is one of the Millennium Development Goals. Vietnam must continue to make progress in this area.
Higher educational attainment in women is an important predictor of women's attitudes toward domestic violence. To date, Doi Moi and the Vietnamese government's commitment to the Millennium Development Goals may have positively contributed to lowering the acceptance of domestic violence. Tailored interventions that focus on education will be important in further changing attitudes toward domestic violence.
Todd Lewis and co-authors discuss development and use of the People's Voice Survey for health system assessment.
Given the evidence from this study, actions to improve access to health care services among people with NCDs are clearly needed. The capacity of primary health care system for the prevention and control of NCDs should be ranked a top priority.
Interventions aimed at reducing use of chewing tobacco or other drugs among older adults in India should consider focusing on recently widowed men and women widowed for any amount of time.
This paper presents the design, optimization, and prototyping of a transverse flux-type-switched reluctance generator (TFSRG) with an integrated rotor consisting of the main and permanent magnet (PM) auxiliary poles. In the initial model, an integrated rotor has a simple structure, consisting of one magnet core and a yoke bar. The yoke bar was radially laminated and inserted in the rotor yoke to minimize loss of the magnetic flux, which flows along the axial direction. We analyzed the cogging to
This study investigated the determinants that made LFHC sustainable, and the findings suggested the importance of forming a cooperative community and implementing social rehabilitation for sustainable leprosy control. More exploration on transferring this model to other leprosy colonies will have great impact in maintaining sustainable care for leprosy patients. Furthermore, this research may highlight the importance of sustainable development in policies targeting neglected tropical diseases be
This paper proposes a novel transverse flux type permanent magnet reluctance generator (TFPMRG), which contains a permanent magnet (PM) in its U-shaped salient stator pole. A U-shaped stator core is designed with the short flux path to reduce the mutual effect between phases. Moreover, the proposed TFPMRG shape is designed for using PM instead of an excitation circuit to provide the field excitation, which increases the output power and efficiency. Both the transverse flux type switched reluctan
