The emergence of mass communication was seen as a development of human communication in the process of History until even a few years ago. But such a view is challenged, today, by the critical approach. In short, the critical viewpoint is based on the fact that the technological development of mass communication has not necessarily resulted in the free press. We can find many evidences in the communication history which prove this critical estimation right. If mass communication really develop, it must follow democratization of communication channel, and such a democratization must mean popular participation in the process of production as well as stpending of message. Thus we must focus on this aspect to study mass communication rationally.

The importance of wild plant resources along with the development of high biotecyhnology is highlighted for exploitation of new materials which can make the added value. The goal of this study is providing fundamental data bases for developing new materials through the analyses of morphological characteristics, antibiotics and molecular cytogenetics in Baegseon (Dictamnus dasycarpus Turcz.). Baegseon has several characteristics; there are two types of flower color, pink and white, the seed germination starts about February 20th, the maximum flowering season is around May 17th in southern Korea, the growth period is about 60 days. The number of chromosomes are 2n=2x=36, the size of chromosomes in metaphase is $4.2{\sim}8.1{\mu}m$. The amount of 2C nuclear DNA is 1.93pg, and there is no variation of genome size amoung varieties. The extraction juice of baegseon young roots has the excellent antibiotic activity against the mold (Botrytis cinerea).
