Objectives : The term ByunJeung is usually used to represent the characteristic of Korean Medicine. However the meaning of ByunJeung has not been consistent. After the 1980s when Traditional Chinese Medicine was introduced into Korea, the meaning of ByunJeung in Korea became diverse. In this paper, we aimed to research how the meaning of ByunJeung has been varied. Methods : We used four major journal database in Korea to search articles related to ByunJeung. Using the terms such as "변증" and "辨證", which mean ByungJeung in Korean and Chinese, we collected 500 articles in total. Among them, we chose only 61 articles selectively which mainly focused on the meaning of ByunJeung. We categorized those according to the specific meaning of ByunJeung which each article used, and qualitatively analyzed those articles. Results : Articles related to ByunJeung were categorized into three different groups. The first group was for the articles which dealt with changing meanings of ByunJeung. The second group was for the articles which focused on the modernized meaning of ByunJeung. The third group was for the articles which was on the traditional meaning of ByunJeung. Conclusions : The term ByunJeung holds a key concept in the current field of Korean medicine. Nevertheless, since the meaning of ByunJeung has been diverse, it often caused confusion among the people who used the term ByunJeung. Therefore we need to clarify the exact meaning when we intend to use the term. Also there should be a further discussion on the meaning of ByunJeung in the field of Korean medicine to facilitate better understanding on the characteristic of Korean medicine.
