Purpose: This study was intended for the enhancement of the elderly's quality of life helping them overcome their physiological changes about aging and reinforcing their vitality. Methods: An nonequivalent control group post-test design was used for the study. The methods to perform the abdominal respiration exercise and to blow the pan-flute were demonstrated to 31 experimental subjects and 36 control subjects. The eight-week 30 minute daily home respiration exercise recipes were prescribed to the subjects. Mobile spirometers were used to measure FVC, $FEV_1$, $FFV_1$ / FVC, $SaO_2$, breathing discomfort. Daily life satisfaction scores were recorded. Music therapy accompanied the eight-week respiration program. A post-test was performed in the same manner as the pre-test. The gathered data were analysed by SPSS/WIN program. Results: 1) The pulmonary function and daily life satisfaction were significantly improved in the experimental group. 2) Both the experimental and control groups did not show significant differences in $SaO_2$. 3) The breathing discomfort was significantly reduced in the experimental group. Conclusion: The respiration exercise program for the elderly through the pan-flute improves the respiration activity of the elderly and enhances their daily life satisfaction scores. Therefore, this program produces effects in enhancing the quality of life for the elderly.

에탄올은 금속, 고무 수지를 부식시키고 열화시키기 때문에 FFV 등 알코올 대응차량이 아닌 경우 에탄올 허용도가 제한되고 있으며, 물과의 상호용해성과 흡습성으로 수분혼입에 의한 상분리가 발생하여 혼합가솔린의 유통에서의 취급에 어려움이 야기되고 있다. 또한, 에탄올은 가솔린과 혼합되면 공비현상으로 인하여 50% 유출온도가 크게 떨어지고 증기압이 7kPa 정도 상승을 초래하는 점도 간과하지 않을 수 없다. 따라서, 자동차용휘발유에 에탄올을 혼입하여 사용할 경우, 가솔린기재를 적절히 선택하여 적정품질을 유지하여야 하며 무엇보다도 에탄을 혼입농도에 따른 저장탱크와 주유기 등의 부품에의 영향과 저장시의 상분리 문제를 충분히 규명하여 유통인프라에서의 적절한 대응책이 마련되어져야 한다. 유통 인프라 대응을 위해서는 우선 생산단계에서 수분 혼입을 최소화하기 위하여 저유소의 출하지점에서 서브옥탄가솔린과 에탄올을 라인브랜딩에 의해 제조하는 방법이 가장 타당하며, 수송부문에서는 탱크로리 등의 공급라인인 파이프와 실링 재질 등에 대해서 면밀한 검토가 필요하다고 할 수 있다. 주유소에서의 대응은 에탄을 혼합연료와 직접 접촉하는 연료계 등 부품재질을 내부식성의 재질로 변환시켜야 하며, 수분혼입을 최소화하기 위한 이중탱크 설치, 지하탱크 환기구내의 대기벨브 설치 등이 필요하며, 기타, 품질 및 수분관리 대책 등도 마련되어야 할 것이다.

The purpose of this study was to determine whether respiratory physical therapy might increase the pulmonary function of the patients with stroke or not. Twenty patients with stroke were randomly assigned to experimental and control group. During four weeks, both groups participated in the conventional physical therapy and only the experimental group added in a program of respiratory physical therapy. Respiratory physical therapy consisted of chest mobilization, resistive ventilatory muscle training used the method of PNF technique and relaxed diaphragm breathing. Baseline and post-test measurements were made of vital capacity. inspiratory capacity, expiratory reserve volume, farced vital capacity, forced expiratory volume at one second, $FE1/FVC(\%)$ and maximal voluntary ventilation. Ater four weeks, the experimental group showed the significant improvement in VC(p<.05). FVC(p<.05), FFV1(p<.05) md MVV(p<.05). However, the controll group showed no significant differnece. As compared th the relationship of dependent variables between the experimental group and control group. experimental group showed the significant difference in VC(p<.01), FEV1(p<.05) and MVV(p<.05). These findings suggest that respiratory physical therapy can be used to improve pulmonary function in stroke patients. Also, respiratory physical therapy should be performed for at least four weeks and be followed by the continuous respiratory exercise programs.

The permeation properties of $O_2\;and\;N_2$ were measured for bromobisphenol A polysulfone(BPSf), bisphenol A trimethylsilylated polysulfone(TMSPSf) and their blend membrane to investigate the structure-properties relationships. BPSf shows relatively high permselectivity. It can be explained that the strong polarity of bromine in BPSf increases chain packing ability. In this case the distance of polymer chains is reduced by increasing of interchain interaction by induced dipole. TMSPSf shows relatively high permeability. The higher value of permeability coefficients for TMSPSf is due to the substitution of very bulky trimethylsilyl groups. The replacement of phenyl hydrogens of bisphenol A polysulfone(PSf) with trimethylsilyl groups results in higher fractional free volume(FFV). In this work, taking into account the complimentary features of BPSf and TMSPSf, BPSf/TMSPSf blend was prepared and the compatibility in mixing are examined. The BPSf/TMSPSf blend shows higher permeability than commercial PSf, with minimum loss of selectivity. The miscibility of the BPSf/TMSPSf blend is confirmed by the single glass transition temperature.
