Regarding language,what is the percentage of English, Konglish,Korean andChinese in the signs?Regarding location, does the percentage change according to locale (main streets, alleys, inside stores and on street vendor signs)? Does it change in relation to various districts in Seoul (specifically, Gangnam, Sadang, Ttukseom, Itaewon, Insadong, Namdaemun and Dongdaemun markets)? Does it change in relation to cities in Korea (Bundang, Suwon, Shinduri and Busan)? Does it change in relation to other sites (Everland [theme park in Yongin], public transportation and bridges)? Regarding domains, are there certain domains where English can be expected to either exist or be absent? At the theoretical level, are the social stratification, gravity or cascade models supported by the data?
