Purpose: This study was to examine the effects of foot reflexion massage on sleep disturbance, depression disorder, and the physiological index of the elderly in nursing homes. Method: The research design was a non-equivalent control group pretest-posttest quasi-experimental study. The subjects in this study were 50 elderly people who resided in two different nursing homes in the same region. An experimental group and a control group were organized with 25 subjects respectively, and foot reflexion massage was provided for 12 sessions, 30 minutes per session. The selected dependent variables were sleep disturbance, depression disorder, and physiological indices(blood plasma serotonin, serum cortisol), which were all measured before and after foot reflexion massage was offered. Data analysis included $x^{2}$-test, t-test, paired t-test, and ANCOVA, using the SPSS program package. Result: 1. The experimental group improved sleep quality more than the control group. 2. The experimental group had less depression disorder than the control group. 3. The experimental group had higher serotonin levels than the control group. Conclusion: It's necessary to give foot reflexion massage as a successful nursing intervention to elderly who undergo a change in sleep, and suffer from a depression disorder due to a deterioration in sleep.

Purpose: This study was to evaluate the effects of foot reflexology on blood pressure, serum lipids level and life satisfaction in essential hypertension patients. Method: The research design used was a nonequivalent control group pretest-posttest design. Foot Reflexology was used as the experimental treatment from June 23rd, 2003 until August 31st, 2003. Thirty-four subjects were assigned to an experimental group(18) and control group(16). Foot Reflexology was administered twice a week for 6 weeks and self foot Reflexology was administered twice a week for 4 weeks on the experimental group. Result: There was a significant decrease in systolic blood pressure but no significant decrease indiastolic pressure in the experimental group compared to the control group. The total cholesterol level in the experimental group compared to the control group was not significantly decreased after foot reflexology. However, the triglyceride level in theexperimental group compared to the control group was significantly decreased after foot reflexology. On the other hand, high density lipoprotein and low density lipoprotein levels in the experimental group compared to the control group was not significantly decreased after foot reflexology. Life satisfaction in the experimental group compared to the control group was significantly improved after foot reflexology. Conclusion: The results proved that foot reflexology was an effective nursing intervention to decrease systolic pressure, and triglyceride but not for the blood cholesterol and to improve life satisfaction. Therefore, blood cholesterol should be further evaluated in a larger group of subjects and for a longer period. Further research is regarded as necessary to evaluate and to compareeffects of self-foot reflexology and foot reflexology.

Axial type 가상음극발진기를 이용하여 전극의 기하학적 구조와 고출력 마이크로파의 출력 특성을 분석하고, 최대 파워의 조건에 대한 전자기기 효과를 알아보았다. 고출력 마이크로파 발생 장치인 Vircator는 강렬한 상대론적 전자빔 발생장치로 최대전압 600 kV, 최대전류 88 kA, 펄스폭 60 ns의 특성을 가진다. Anode와 cathode의 간격은 4 mm로 최적화 하였고, 이 조건에서 마이크로파의 출력 특성을 분석하여 보았을 때 WR-137 수신안테나에서 최대 출력143 MW와 5.4 GHz의 진동수를 측정하였다. 출력 효율을 증가시키기 위해서 도파관 중앙에 폭이 10 mm인 반사판을 사용하였고, 그 결과 반사판이 공진구조에 기여하여 정상파(standing wave)를 형성하여 마이크로파 출력 효율 향상하여 WR-137에서 최대 549 MW의 출력을 보였다. 향상된 마이크로파의 출력을 이용하여 각도와 거리를 변화해 가며 컴퓨터와 전자소자로 제작된 회로에 대해 전자기기 효과 실험을 실시하였다. 그 결과 컴퓨터의 경우 $0^{\circ}$ 1 m에서 hard kill 상태가 되었다. 전자소자 회로의 경우는 $0^{\circ}$ 30 cm에서 hard kill의 상태로 되었다. 또한 면적 대비 출력 파워로 비교 했을 경우 약 $0.484\;{\mu}J$의 마이크로파의 영향임을 확인할 수 있었다.
