The analysis of frequency, cross table, the difference of mean was practiced. The focus of the analysis was to find the difference of attitudes between Korean Oriental medical doctors and Western medical doctors. The results of the analysis showed that Korean Oriental medical doctors are more active to the cooperated medical treatments than Western medical doctors. They also have more experience. And both of Korean Oriental medical doctors and Western medical doctors agree to the necessity of the cooperated medical treatments. But the preferred combination pattern of Korean Oriental medicine and Western medicine was different between two medical groups. Korean Oriental medical doctors prefer the one to one combination pattern. But Western medical doctors prefer to Western medicine centered combination pattern.
