The Ministry of Environment established a data base platform called environmental statistic portal. From there we collected environmental statistics including sulfurous acid gas, fine dust, carbon monoxide, nitrogen dioxide, household waste, domestic waste, construction waste, the number of factories, the amount of waste water, the amount of organic matter, etc. We collected the number of tuberculosis (TB) patients from National Health Service in Korean Statistical Information Service. We consider the number of TB patients and environmental statistics as a dependent variable and predictors, respectively. A multiple regression analysis is performed to find out significant predictors that affect the number of TB patients. A deep analysis is done to discover the relationship between significant predictors and the dependent variable depending on national district areas, i.e. Gu or Goon, by use of a multivariate analysis and a covariance analysis.
