(((A subtropical island the size of Hong Kong marooned in the midst of the Yellow Sea, yet it nevertheless features testbeds for green energy, wideband broadcasting, and ubiquitous RFID fish-farming. Plus the august presence of the "Jeju Cultural Technology Education Center," the "Jeju
Knowledge Industry Promotion Agency," "Cheju National University"
and the "Jeju Free International City Development Center.")))
(((Every tiny, quiet place out on the fringes is always at the "center" or the "heart" of something.)))
