We have sent the 1000 hair samples to USA and received the results from USA because the programs for the interpretation of Tissue Mineral Analysis (TMA) result is not opened yet in Korea. Therefore, the study will analyze the relationship between the hair for Korean and minerals and make a classification system. To achieve the goal, first of all, we coded the results of patients and classified the analyzed results which are the interrelationship between the minerals and dietary situation and the heavy metals and diseases through the statistical methods. Finally we classified 8 metabolic type using decision tree classifier.
