The purpose of this study was to examine the changes of phsical fitness, blood lipid, and lipoprotein before & after muscle endurance weight training of 12 weeks on the 8 middle-aged women of 39-51 years old. The method of muscle endurance weight training during 12 weeks was established to practice the training of 3 sets through repeated frequency of 30-35 times with the loading of the above subjects who retained 30-40 percentage of 1 RM. The results are as follows; 1. Weight, body fat, %fat, LBM, and BMI are founded to have a significant decrease. respectively, in the change of body composition(P<0.01). 2. Grip strength, back strength, trunk flexion, trunk extension, and vital capacity are founded to have a significant increase, respectively, in the change of physical fitness, while light reaction is founded to have a significant decrease(P<0.01). 3. HDL-C, APO-AI, APO-AII, AND FFA are founded to have a significant increase, while T-C, TG, LDL-C, APO-B, T-C/HDL, LDL-C/HDL-C, and AI are founded to have a significant decrease, respectively, in change blood lipid and lipoprotein(P<0.01). As the above results, muscle endurance weight training like aerobic exercise, especially, in middle-aged women, is demonstrated to have a positive effect in the improvement of body composition, the enhancement of physical fitness, and the metabolism of blood lipid lipoprotein.

The purpose of this study is to examine the changes of body composition, serum lipids and lipoproteins before & after circuit training of 12 weeks on the 7 middle-aged women 40-51 years old. The circuit training during 12 weeks was established to be 9 items, and then the training loading was practied to have 1/2 of maximum repeated frequency during 1 minute The results are as follows: 1. Weight, % fat, and BMI are found to have a significant decreased(p<0.05) of 3.0%, (p<0.01) of 4.30%, and(p<0.01) of 2.99%, in the change of body composition, respectively. LBM is found to have a significant increase(p<0.05) of 2.75% in the change of body composition. 2. TC and TG are found to have the decrease of 2.68% and 4.94% after training respectively in the change of serum lipids, but not to have a significance. And then also LDL-C is found to have the decrease of 10.54%, but not to have a significance. And then HDL-C and FFA are found to have a significant increase of 27.83% and 10.30%, respectively(p<0.01) 3. TC/HDL, LDL/HDL, and AI are founded to have a significant decrease of 25.08%, 31.25%, and 32.30%, respectively, in the change of arteriosclerosis index(P<0.01). As the above results, the circuit training like aerobic exercise, especially, in middle-aged women, is demonstrated to have a positive effect in the improvement of the beauty, body composition, arteriosclerosis, and the metabolism of serum lipid-lipoprotein.

Under lean burn condition region, main hazard exhaust components are NOx and abundant hydrocarbons. Therefore, NOx abatement using hydrocarbon reductant was most desirable. During last twenty years, NO direct decomposition reaction by Cu-ZSM-5 was suggested with strong possibilities. However, at actual engine exhaust condition(i.e. hydrothermal atmosphere) that wasn't work its own function. In this paper, we tried in order to overcome these disadvantages, other precious metal, especially Pt, Ir, Rh ion exchanged zeolite catalysts were used for lean deNOx catalysis.

The aim of this study is to analyse the acoustical characteristic of multi-purpose hall. The acoustic parameters and the subjective responses are compared and analyzed. The objective facilities used in this study are composed of four halls : BU, HN, JD, MP which are matte use of multi-purpose hall. The physical parameters compared and analyzed in this study are SD(standard deviation) of SPL(sound pressure level), RT(reverberation time), D_(50)(definition), C_(80)(clarity) and STI(speech transmission index), and the subjective parameters are about loudness, reverberation, intelligibility and satisfaction.
