Physicochemical properties of defatted and 1% palmitic acid reincorporated rice starch were investigated comparing with nondefatted starch. Amylose content of defatted starch was higher than that of nondefatted and reincorporated starch. Transmittance, swelling power and solubility of nondeffated and reincorporated starch exhibited two stage behavior but these behaviors were disappaered by defatting. All starches showed a typical A type in X-ray diffraction but relative crystallinity was decreased by defatting. Also by defatting, peak viscosity and break down of amylogram were disappeared and set back was increased.

Rheological propreties of defatted and 1% palmitic arid reincorporated rice starch solutions were investigated, comparing with nondefatted starch. Flow behavior of gelatinized starch solutions(3-7%) revealed pseudoplastic behavior with yield stress, but yield stress was decreased by defatting. Relationship between logarithmic consistency index and concentration of nondefatted starch solution was linear with single slope, but the slopes for defatted and reincorporated starch solutions were different at 3-5% and 5-7% starch concentration. The activation energies for 7% starch solutions were estimated to be 3.14-4.76 kcal/g mol and increased slightly by defatting. All thre starch solutions above 4% concentration exhibited hysteresis phenomena, but by defatting, humping phenomena was observed and thixotropic behavior were increased slightly.

In terms of world system theory, the historical period of Yanbian area was divided into 3 parts: Japan colonial period which was assigned to the periphery of world system, socialist period which escaped from the world system, and the reform-open period that was reincorporated to world system. The cultural character of each period was studied. The conclusions are as follow. During the period of periphery of world system, Yanbian area as an area where the massed Korean people lived, was dominated by Korean peninsular culture. However, Yanbian area was also affected by the Japanese and Chinese cultural assimilation policy. During the period that Yanbian area aparted from the world system, it was affected by the requirement of unique socialist culture assimilation, and traditional cultures were hard to keep. During the period of reincorporation to the world system with lighten of minority policy by Chinese government, traditional national culture begin revived, but due to extend intercourse of Yanbian with China mainland and Republic of Korea, China-Korean culture of Yanbian area was strongly affected by Chinese and Korean culture too.
