Bridging the urban–rural health divide through a comprehensive digital ecosystem — empowering older adults to live where they belong, healthier and longer.
Dr. Chang HeeKyung is a Professor at the College of Nursing, Gyeongsang National University, and a researcher at the Sustainable Health Research Institute. She earned her B.S.N. (1995), M.S.N. (2002) and Ph.D. (2013) from Seoul National University College of Nursing.
Her research centers on frailty, intrinsic capacity, and community-based digital health interventions that enable older adults to age in place with dignity. She is the Principal Investigator of the DREAMS project — an NRF-funded longitudinal study developing a comprehensive digital health ecosystem across urban–rural communities.
With over 50 peer-reviewed publications since 2009, her work spans healthy aging, frailty screening, sarcopenia, dysphagia, person-centered care, digital storytelling, and evidence-based nursing.
Our publications are organized into six thematic streams. Each card presents the research focus and all related publications.
Digital Rural-urban Ecosystem for Active Management & Successful Aging — a 3-year longitudinal study building a comprehensive digital health ecosystem for aging in place.
464 community-dwelling older adults (mean age 78.4; 67.9% female) recruited from 11 community-based sites in urban and rural Jinju — urban 268 / rural 196, March–December 2024. WHO ICOPE Step 1 validated against Korean reference standards (CIST, MNA-SF, GDS-15, SPPB); five analyses completed.
A two-tier design compared by intervention intensity, delivered with the Jinju City Public Health Center and 23 partner institutions. Tier 1 intensive intervention (n=100) runs alongside Tier 2 AI-based monitoring (1,000+ registered users), while the three-tier platform is built during the pilot.
Full operation of the three-tier platform: data collection → risk prediction engine → tailored intervention output. Cost-effectiveness analysis of each tier informs a scalable model, with longitudinal prediction and evidence-based policy recommendations.
DREAMS is grounded in the belief that healthy aging happens best where people belong — in their own communities, supported by a responsive digital ecosystem.
Beyond disease management — DREAMS promotes vitality, intrinsic capacity, and wellbeing across individual, community, and environmental levels.
Urban residents show multi-step sequential pathways; rural residents show simplified appetite-driven pathways. Bridging this gap is DREAMS' core mission.
Our poster on ikigai at UTNIC 2026 drew interest from researchers at the University of Tokyo, and correspondence is now underway toward a joint study of ikigai in later life. Exchange with Kyoto Prefectural University of Medicine is the most developed of the current links. Measurement harmonisation with TOOTH and TULIP/TULIPS was discussed at Keio University CSMR; a formal collaboration there has not yet been decided.

DREAMS supports healthy aging through an ecosystem in which the individual, family and care, community, institutions, and policy are organically connected — the structure carried in our logo.
The first Korean diagnostic accuracy study of the four assessable non-sensory ICOPE Step 1 domains (n=464). Front Public Health 2026;14:1897282.
Prevalence looked similar across urban and rural sites — almost nothing else did. Rural locomotion sensitivity was 85.5% against 53.2% in urban residents, using the same item and the same protocol.
Conversely, urban residents were far more likely to be detected for cognition (adjusted OR 4.82) and vitality (OR 4.10). A single uniform national screening protocol does not perform uniformly.
The Year 2 intervention is delivered where older adults already gather — the gyeongnodang (village senior centre). In partnership with the Jinju City Public Health Center, the programme runs at 15 village senior centres across rural Jinju with 177 participating older adults. The research team delivers the intervention directly at five of these centres; at the remaining ten it is delivered by interventionists employed by the public health centre, working from centre-specific guidance the team prepares from the baseline assessment.
Baseline assessment is returned to each centre as a profile of its own older adults — depression, cognition, fall risk, nutrition, grip strength, hearing and loneliness — so that every site emphasises what its participants actually need. One centre may be appetite-driven, the next dominated by fall risk.
Delivering at the centre removes the travel barrier a clinic-based programme would impose, and places the intervention inside an existing social structure, so taking part is a continuation of daily life rather than an appointment.
Each 12-week cycle closes with a graduation. Participants receive a certificate and a wall calendar made for their own centre, carrying photographs from their twelve weeks together and the activities they chose to keep doing. Four of the five centres the research team runs directly have now graduated; Motan 못안 follows on 29 October 2026.
With the Jinju City Public Health Center, the team has built a digital dashboard that brings the health status of 1,000 community-dwelling older adults onto a single screen. Built on the WHO ICOPE (Integrated Care for Older People) framework, it reads the five intrinsic capacity domains alongside physical, psychological and social frailty and activities of daily living, so that the public health centre can identify at-risk older adults early and prioritise who is seen first.
The intervention it feeds was designed from the team’s study of 464 older adults in Gyeongnam, which found that cognitive function and psychological capacity mediate the path from frailty to dependence in daily living. That is why the programme addresses cognition, nutrition and psychological domains alongside physical activity, rather than exercise alone.
The work sits alongside Korea’s Integrated Care Support Act, which took effect in March 2026 and links medical care, long-term care and community support around the local area. The dashboard is intended as the mechanism that detects health risk early and routes an older adult to the service they need.

“This dashboard and the integrated intervention are an attempt to analyse older adults’ health comprehensively, on the basis of data, and to deliver tailored care where it is most needed,” said Prof. Chang. “Through our partnership with the Jinju City Public Health Center, I hope the findings contribute in practical terms to the health of older adults in this community.”

Two international conferences and four institutional visits across Tokyo, Omuta and Kyoto, 19–31 July 2026.
An official overseas research visit funded by the National Research Foundation of Korea, undertaken to present the DREAMS project’s findings and to build the groundwork for Korea–Japan research collaboration. Alongside the two conferences, the team visited four institutions whose work bears directly on DREAMS — community-integrated dementia care, gerontological nursing, longitudinal ageing cohorts, and digital tools for older adults’ health.
These materials are being used to standardise instruments and harmonise data for the DREAMS cohort’s follow-up wave, and as the basis for designing joint Korea–Japan studies and for participating in international ageing-cohort consortia. Interpretation support made it possible to hold substantive discussions at each institution, and all of the hosts agreed to continue talks on joint research, data harmonisation and reciprocal visits.
Bringing together expertise in gerontological nursing, clinical evaluation, data analysis, and research administration.
We welcome collaborations with researchers, clinicians, and community partners committed to healthy aging and digital health innovation.
