Brief summary: After administration of besifovir preparations different from each other to healthy subjects, the investigators evaluate equivalence of bioavailability of LB80331.

Detailed description: The purpose of this study is to evaluate equivalence of bioavailability of LB80331 preparations different. Following the randomly allocated sequence group administer the relevant test drug for 1 time according to the determined schedule of Treatment A and Treatment B in each of the periods.
