Sure, no problem. There were two Korean studies I looked at:

Journal of Korean Society for Health Education and Promotion, Vol.24, №5, 2007. Study done by Min Seok Ko PhD course Student and Master Students’ team of the Graduate School of Health and Environment at WonKwang University for their collected Korean data

Kim JI. 2005. Social-environmental factors by region for cause of death of elderly people in Korea. Journal of the Korean Gerontological Society 25(2): 9–19.
