  • PVA blend films were prepared by solution blending method for the purpose of useful antibiotic polymers. Characteristics properties of blending films such as elongation and tensile strength were determined. Tensile strength and elongation were rapidly reduced as increasing the blending ratio of natural polymer. Blend films were found that phase separation was occured as more than 25wt% increasing the blend ratio of chitosan. Also, The antibiotics of blend films were examined against gram(+) and gram(-) by disk susceptibility test. As a result, kind of blending films to show the highest antibiotics was chitosan 20wt% and the selectivity of mold strain was observed.

  • 1. Objectives The pesent study purposed to examine Dongmu Lee Je-Ma's Sasang philosophy from the viewpoint of Che-Yong relation and to understand the effect of Che-Yong relation on Dongmu philosophy. 2. Methods First, we briefly compared the concept of Che-Yong relation in Jeongju philosophy, which has a dualistic philosophical structure, with the concept of Han Suk-Ji's harmonious Che-Yong relation, which has a monistic philosophical struaure and, based on rhe result, analyzed the characteristics of rhe concept of Che-Yong in Dongmu philosophy focused on Seongmyeong rheory, Sadan rheory and Hwakchung theory in ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$. 3 Results and Conclusions Jeongju philosophy is different from Dongmu philosophy in irs philosophical struaure characterized by Che-Yong relation, and the concept of Che-Yong in Dongmu philosophy forms the characteristics of Han Suk-ji's monistic harmonious Ole- Y ong relation. This produces results as follows. (1) Form a universal view of human beings centering of man's autonomous will and possibility. (2) Have a philosophical structure understood nor as a partial thought but as a total thought. (3) Assert that man has a good nature fundamentally and is obliged to practice goodness. (4) Assume that all human beings are equal. (5) It is assumed that the structural characteristics of harmonious Che-Yong relation in Dongmu philosophy can be the ground of definition of Silhak (practical science) in Oriental philosophy. It can be said that the realities of the universe and human beings can be discussed in philosophical structure with the logic of harmonious Che-Yong relation based on the unity of time and space. The philosophical logic based on the tealities can be defined as Silhak.
