This study measured the smouldering temperature of dust layer for various combustible natural polymer material by practical apparatus. The dust layer was either put on the preheated plate of constant temperature, or formed with cylinderical metal sleeve of various diameters and depths at room temperature and then heated up to a pre-determined smouldering temperature. Plots of arrival times versus smouldering temperature were made to compare the smouldering characteristics with kinds of dusts. The natural polymer material was divided into theree groups by characteristics of smouldering mechanism. This groups are cellulose group, lipide group and glucose group.

This investigation was performed to study the antioxidant activities of Hovenia dulcis THUNBER var. koreana Nakai fruits extracts and the effect of Hovenia dulcis fruits extracts on glucose, lipid metabolism in diabetic rats. DPPH free radical scavanging activitiy and superoxide anion radical Scavenging of Hovenia dulcis fruits $80\%$ methanol extracts were $0.06\pm0.002mg$ polyphrnol/ml and $0.l2\pm0.00lmg$ polyphmol/ml, respectively. Hovenia dulcis fruits $80\%$ methanol extracts were partitioned into hexan, dichloro methane, ethyl acetate and butanol, successively. Ethyl acetate fraction were good antioxidant activity. Streptozotocin (45 mg/kg body weight, i.p.) induced diabetic rats showed a significant increases of plasma glucose, triglyceride and total cholesterol. Concomitantly significant decrease of plasma high density lipoprotein. Glutathione level were decrease in cytosol of liver. Lipid peroxide were increase in microsome of liver. Group 1 and 2 were treated with Hovenia dulcis fruits ethyl acetate extracts 50 mg/kg body weight and 20mg/kg body weight for 24 days, individually. Group land 2 rats showed decreased plasma glucose, triglyceride, total cholesterol and lipide peroxide in microsome of liver tissue of rats, and increased plasma high density lipoprotein and glutathione in cytosol of liver tissue rats. The result suggest that Hovenia dulcis THUNBER var. koreana Nakai fruits extracts may effectively normalize the impaired antioxiants status in streptozotocin induced diabetic rats. Hovenia dulcis fruits ethyl acetate extracts were used to improve the imbalance between free radicals and antioxidant system due to the diabetes.

Purpose: This study was to develop and prove the effects of aself management compliance promotion program for primary hypertension patients who reside in rural communities. Method: The content of the self management compliance promotion program developed by this study was as follows: A leader trains patients as a group or individually, in walking, education and green tea therapy from the first to twelfth week. From the thirteenth to twenty fourth week, the patients should perform walking and green tea therapy by themselves. One hundred twenty subjects volunteered to participate in the study, who were among those registered as hypertension patients in the 14 community health clinics located in Chungcheongbuk-do. Result: Systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol, triglyceride, step width, and degree of obesity decreased significantly. High-density lipoprotein cholesterol, step length, knowledge of hypertension, and self management compliance significantly increased, Conclusion: A self management compliance promotion program for primary hypertensive patients enhances biophysical index and knowledge on hypertension, thus ultimately suggesting a nursing intervention for promoting self management compliance.
