Radon is a naturally occurring radioactive material formed when uranium and thorium found in the earth's crust or construction materials slowly decay. Internal exposure to radon accounts for about half of the natural background radiation dose of which humans are exposed to annually. Radon is a carcinogen and is the second leading cause of lung cancer following smoking. The association between radon and lung cancer has been consistently reported in epidemiological studies on mineworkers and the general population with indoor radon exposure...

The TB incidence rate and mortality rate in the Republic of Korea are 77 and 5.2 per 100,000 people respectively (2016), which are the highest among the Organization for Economic Co-operation and Development countries. Recently, the Republic of Korea's TB incidence decreased dramatically among people in their teens and twenties. This is largely attributed to the contact investigation efforts in targeting schools over the past few years. However, the TB incidence in the elderly still remains high and is even increasing compared to the past 10 years...

Electronic health records (EHRs) can provide researchers with extraordinary opportunities for population-based research. The National Health Insurance system of Taiwan was established in 1995 and covers more than 99.6% of the Taiwanese population; this system's claims data are released as the National Health Insurance Research Database (NHIRD). All data from primary outpatient departments and inpatient hospital care settings after 2000 are included in this database. After a change and update in 2016, the NHIRD is maintained and regulated by the Data Science Centre of the Ministry of Health and Welfare of Taiwan...

The value of using population data to answer important questions for individual and societal benefit has never been greater. Governments and research funders world-wide are recognizing this potential and making major investments in data-intensive initiatives. However, there are challenges to overcome so that safe, socially-acceptable data sharing can be achieved. This paper outlines the field of population data science, the International Population Data Linkage Network (IPDLN), and their roles in advancing data-intensive research...

OBJECTIVES: Previous studies have shown relatively low correlations between self-reported and accelerometer-assessed physical activity (PA). However, this association differs by socio-demographic factors, and this relationship has not been fully investigated in the general population. Thus, we investigated the correlation between self-reported and accelerometer-assessed PA and whether it differed by demographic and socioeconomic factors among the Korean general population. METHODS: This cross-sectional study included 623 participants (203 men and 420 women) aged 30 to 64 years, who completed a PA questionnaire and wore a wrist-worn accelerometer on the non-dominant wrist for 7 days...
