e number of carbon atoms in alkyl group from 10 to 18 and with higher yields than in the previous methods. The reactivities of antimicrobial agents onto cellulose were examined by Shake Flask Method and by Degree of Luminescence from Inductively Coupled Plasma. Ammonium salt having 16 carbon alkyl group exhibited the maximum activity. The optimum treatment conditions of these ammonium salts were : concentration 1.0% (o.w.f.), treating temperature 3$0^{\circ}C$, and treating time 30 min. Si contents of treated fabrics showed the same result. Hand of the treated fabrics manifested by H.E.S.C., that is, water repellency, flame retardancy, and antistatic property was also evaluated. The results are as follows : Hand of the treated fabrics became softer and bulkier. Water repellency and flame retardancy were not changed but antistatic property became poor.

This study was conducted to evaluate blood pressure associated with body mass index and blood lipids. Study subjects were 3,076 persons (1,623 males and 1,453 females) who visited to General Health Screening Center located in Chonan. Data were collected from 2001 to 2003. Height, weight and blood pressure were measured by a trained nurse. The level of total cholesterol, HDL cholesterol, triglyceride, and fasting blood sugar were selected as biometric test variables. Statistical analysis, such as t-test, simple correlation, and stepwise multiple regression were performed using SAS package program. The mean (standar deviation) of age, BMI, systolic blood pressure, diastolic blood pressure, fasting blood sugar, triglyceride, total cholesterol, HDL cholesterol, and LDL cholesterol in study subjects were 48.4 ±11.8 years, 23,7 ± 3.2 kg/m^(2), 124.6 ± 16.3 mmHg, 80.9 ± 10.7 mmHg, 97.6 ± 24.9 mg/㎗, 154.4 ± 105.6 mg/㎗, 203.2 ± 39.2 mg/㎗, 51.0 ± 12.8 mg/㎗, and 121.8 ± 35.6 mg/㎗, respectively. In multiple regression analysis of BMI and blood lipids on systolic blood pressure after controlling for confounders (age, sex, and fasting blood sugar), BMI, HDL cholesterol, and triglyceride were found to be significant positive independent predictors of systolic blood pressure. In multiple regression analysis of BMI and blood lipids on systolic blood pressure after controlling for confounders (age, sex, and fasting blood sugar), BMI, triglyceride, HDL cholesterol, and LDL cholesterol were found to be significant positive independent predictors fo systolic blood pressure. With above results, it was found that BMI and blood lipids were significantly associated with blood pressure.

3-(Trimethoxysilyl)propylmethyl-S-alkyl sulfonium iodides salts and 4-(2-Trimethoxysilyl)ethyl-N-alkyl pyridinium bromides salts were synthesized with varying the number of carbon atoms in alkyl group from 10 to 18 and with higher yields than previous methods. The reduction rates in no. of colonies and the reactivities of antimicrobial agents onto cellulose were examined by Shake Flask Method, and by Degree of Luminescence from Inductively Coupled Plasma, respectively. Sulfonium salt having 16 and pyridinium salt having 12 carbon alkyl group exhibited the maximum activity. The optimum treatment conditions of these sulfonium salts and pyridinium salts were: concentration 1.0%(owf), treating temperature 30$^{\circ}C$, and treating time 30min. Si contents of treated fabrics showed the same result. Hand of treated fabrics was examined by the Kawabata Evaluation System. Water repellency, flame retardancy, and antistatic property were also evaluated. The hand of the treated fabrics became softer and bulkier.
