Generator is the main equipment of a power plant that generates electric power. The line frequency is 60Hz, since that is operated at 3600rpm in fossil power plant. Therefore, the specific frequency 120Hz by the electromagnetic excitation force is generated inherently. If the looseness of stator at generator happens, abnormal sound that has 120Hz and the harmonic frequency is emitted from generator frame. In that case, binding of end-winding or re-wedging is needed for the reduction of sound level. In case of severe level of sound, belly band can be additionally installed at core. In this paper, the characteristics of generator sound is described and modal data is analyzed after installation of belly band.

In order to study the anti-stress effect of Bunsimgieum, the changes of plasma catecholamine, aldosterone and cortisol levels were measured. In this study author gave immobilization stress to rats, and got the following results: 1. The contents of NE and EPI control group were $2.67{\pm}0.53$, $1.90{\pm}0.22\;ng/ml$, but in sample group the contents were $1.93{\pm}0.67$, $1.15{\pm}0.28\;ng/ml$. The real significance lies in thet only NE show the difference. 2. The contents of aldosterone in control group were $440.69{\pm}37.82\;Pg/ml$, but in sample group $174.64{\pm}42.41Pg/ml$ of aldosterone was measured. The difference was obvious. 3. The cortisol contents in control group were $0.17{\pm}0.03\;ug/dl$, but in sample group $0.28{\pm}0.03 \;ug/dl$ of cortisol was measured. Base on the results above, it may be concluded that Bunsimgieum is effective to prevent to prevent the changes by stress.

신체의 활력을 측정하는 혈압은 다른 어느 측정치보다 변동이 심하고 정상적으로 변할 수 있는 생리적 현상이어서 정확하게 측정하기란 쉽지 않다. 1mmHg 차이의 혈압일지라도, 특히 큰 집단일 경우, 연구목적에서 그 결과를 크게 왜곡 시킬 수 있다. (Wright & dore, 1970). 혈압 측정에는 직접적 방법과 간접적 방법이 있다. 이 중 간접적 방법은 임상분야와 연구분야에서 실제로 넓게 사용되고 있을 분만 아니라 신체로의 직접적 침투하는 방법도 아니고 가격 또한 비싸지 않다. 그러나, 간접적 측정 방법은 혈압에 영향을 끼치는 많은 요인들인 관찰자 편견, 확장기음의 청취음 선택, 관찰자와 환자 사이의 상호관계 때문에 방법론적으로 문제제기가 되기도 한다. 이런 요인을 최소화하기 위하여 가장 타당도가 높은 측정도구의 선택이 필요하다. 도시지역의(Ease Baltimore) 고혈압을 가진 젊은 흑인 남성(연령별/성별/종속별/거주지역) 중 수축기 혈압이 140mmHg 이고 확장기 혈압이 90mmHg인 사람, 또는 확장기 혈압이 90mmHg인 사람, 또는 혈압하강제를 먹고 있는 사람 200명을 대상으로 훈련받은 community health worker(CHW)에 의해 Random-Zero Sphygmdmanometer(RZS)와 Digit Automatic Device(DAD)로 혈압을 측정하게 하였다. 이 중 36명을 무작위 추출하여 regular Mercury Sphygmdmanometer (RMS)로 혈압을 측정하게 했다. Bland 와 Altman에 의해 제기된 두측정값의 차이에 대한 scattergram(일치도 검증법)과 AAMI(Association for the Advancement of Medical Instrument) 기준, BHS 기준, Central Tendency와 숫자선호도로 검증되었다. AAMI와 BHS 기준에 의하면 확장기 혈압에서 RZS와 DAD의 일치도와 평균을 중심으로 더 넓게 퍼져있어 낮은 일치도를 보였으며 또 DAD와 RMS의 혈압치는 숫자 선호도를 볼 수 있는데 특히 RMS는 더 뚜렷하게 나타났는데 확장기 혈압의 최빈치(30.6)는 100mmHg이었다. 혈압치들이 가장 가까이 "0"점으로 치우쳐져 있었다. RZS의 Central tendency는 DAD와 RMS보다 뚜렷하였다. 결론적으로 RZS는 이 연구목적으로 가장 적절함을 보여준다.

This study was performed to investigate the effect of Bunsimgieum on antitumor effect after sarcoma-180 cells transplantation into peritoneal cavity or left groin and immune responses on the depressed immunity induced by methotrexate in mice. The Bunsimgieum extract of 10mg/kg was orally administered 14 days for antitumor effects and 21 days for immune responses. 50% inhibitory concentration($IC_{50}$) of SUN-1, SUN-C4, and SUN-396 cancer cell, mean sunvival days and body weight of tumor bearing mice, and growth of tumor mass for antitumor effect; delayed type hypersentivity, hemagglutinin titer, hemolysis titer, rosette forming cells, natured killer cell activity, lymphocyte transformation, productivity of interleukin-2, and phagocytic activity for their immune responses were measured in ICR mice. Significance in antitumor effect is noted in the enlongation of mean life days and inhibition of tumor growth(p<0.01, respectively). Significance of immune responses is also noted in hemolysis titer, lymphocyte transfumotion, IL-2 productivity, phagocytic activity, and natural killer cell activity at E/T ratio 100:1(p<0.01, respectively). Significant in rosette cell formation was seen at dosage of 20mg/kg(p<0.01). However, Difference of body weight as antitumor effect, delayed type hypersensitivity, and hemagglutinin titer were not shown significantly. According to the above results, it could be suggested that Bunsimgieum has prominent antitumor and immunity enhancing effect.

Objectives: The purpose of this study was to confirm the anti-amnesic effects of Bunsimgieum (BSGE) through its favorable acetylcholine (ACh) and, acetylcholinesterase (AChE) activity, choline acetyltransferase (ChAT) mRNA expressions, and antioxidant effect on scopolamine (Sco)-induced memory impairment in C57BL/6 mice. Methods: Six groups, a total of 20 intact or 100 Sco-induced mice were used in this study, based on their body weight. Half of each group underwent passive avoidance tests and the measurement of hippocampus AChE activity, ACh content, and ChAT mRNA expression, The remaining half of each group underwent a Morris water-maze test and antioxidant defense system measurement as well. Results: Significant reductions in the step-through latency times from the passive avoidance test and reductions in the escape latency times from the Morris water-maze test were observed with increases of hippocampal AChE activities and, reductions in ACh contents and ChAT mRNA expression in hippocampus, as a result of Sco intraperitoneal treatment, in this study. Additionally, the increases in cerebral cortical MDA levels and, reductions in GSH contents, SOD activities, and CAT activities were demonstrated in the Sco control mice compared with the intact vehicle control mice, respectively. However, 28 days of consecutive oral pre-treatment of BSGE hot water extracts of 400, 200, and 100 mg/kg, respectively, markedly and dose-dependently inhibited Sco treatment-related amnesia. Conclusions: The results demonstrate that the oral administration of BSGE hot water extracts reduces Sco-induced memory impairment, through preserving ACh, related to ChAT mRNA expressions, causes AChE inhibition, and enhances the cerebral antioxidant defense system.

Background: The aim of this study is to investigate the use of heart rate variability on a stroke patient with autonomic dysfunction and the effectiveness of Bunshimgi-eum. Case report: The patient showed autonomic dysfunction, including chest discomfort, 煩燥 (sweating, anxiety, insomnia, nausea, lightheadedness), and abdomen discomfort (dyspepsia, heartburn) after ischemic stroke. She was treated with a herbal medicine (Bunshimgi-eum) through complex Korean medicine treatment. The effect was evaluated using heart rate variability (HRV), Mini-Mental State Examination-DS (MMSE-DS), mean pulse rate, and subjective percentage of symptoms. After treatment, the HRV score, MMSE-DS score, and subjective percentage of symptoms improved, and the pulse rate decreased from the upper boundary value. Discussion: The results suggest that HRV may be useful in evaluating stroke patients with autonomic dysfunction and that Bunshimgi-eum is suitable for treatment.

In this case report, we describe the effects of Korean Medicine therapies, including Bunshimgi-eum, on a patient hospitalized with insomnia due to fibromyalgia in a Korean Medicine Hospital. We treated the patient with Bunshimgi-eum for 21 of 27 hospital days. Post-treatment, we used the Insomnia Severity Index (ISI) to measure the severity of insomnia. To determine the severity of multiple pain, including neck, low back, Lt. shoulder, Lt. elbow, Rt. knee, and hand, we used the Numerical Rating Scale (NRS). For evaluation of generic health status, we used the European Quality of Life-5 Dimensions (EQ-5D) scale. After the treatment, the patient's clinical symptoms improved, according to the ISI, NRS, and EQ-5D. The results of this case study suggest that Korean Medicine therapies, including Bunshimgi-eum, may have positive effects as a treatment for insomnia related to fibromyalgia.

Objectives : The purpose of this research is to examine the effect of Bunsimgi-eum on the chest discomfort of Hwa-byung's major symptom. Methods : In this randomized, double blinded, placebo-controlled study, we planned to give Bunsimgi-eum or controlled medication for major symptoms of Hwa-byung. As preparatory research, 100 mm Visual Analogue Scale(VAS) for chest discomfort, the Hwa-byung' major symptom was measured as the 1st evaluative instrument, and Likert scale for major symptom of Hwa-byung, Korean State-Trait Anger Expression Inventory(STAXI-K), Korean State-Trait Anxiety Inventory(STAI-K), Korean Beck's Depression Inventory(BDI-K) and Heart Rate Variability(HRV) were also measured as the 2nd evaluative instrument at the before treatment. Results : Clinical characteristics-vital signs & demographic characteristics showed no significant difference between both groups. The characteristics of disease-chief complaint, pattern Identification, period, etiological factor, etc, also showed no significant difference between both groups. There were almost no Coincidence between pattern identification & weight of Hwa-byung's major symptoms. The results of Chest PA, EKG and clinicopathologic examination showed no significant difference between both groups. There were no significant difference between both groups in all valuation scales; 100 mm Visual Analogue Scale for chest discomfort, the Hwa-byung' major symptom was measured as the 1st evaluative instrument, and Likert scale for major symptom of Hwa-byung, STAXI-K, STAI-K, BDI-K and HRV. Conclusions : We considered that establishment of experimental group and controlled group was objective and worth conducting this research. And this methodology is expected to be applied to the subsequent research. And also, we hope to make up for this study through various study and discussion.

Object : This study was designed to research whether the protection and inhibitory effects of cardiovascular diseases in L-NAME induced rat or ECV 304 cell lines through the Cell morphological pattern, Tunel assay, LDH activity, heart rate, blood pressure and immunohistochemistric analysis by Boonsimgieum water extract Methods : Nitric oxide(NO) play an important role in normal and pathophysiological cells including as a messenger molecule, neurotransmitter, microbiocidal agent, or dilator of blood vessels and artheriosclerosis, hypertension, myocardial infarction, respectively. Endothelial cell products can modulate the magnitude of a response to a vasoconstrictor, as evinced by the greater constriction after endothelium removal or NO synthesis blockade. To investigate that Boonsimgieum in the potential contribution of the levels of nitric oxide generated by endothelial nitric oxide synthase (eNOS) and the mechanisms of protection against NG-nitro-L-arginine methyl ester (L-NAME), human ECV 304 cells, which normally do not express eNOS, were expressed by L-NAME. L-NAME stimulated rat or cells were found to be resistant to injury and delayed death following the Boonsimgieum. Inhibition of nitric oxide synthesis abolished the protective effect against L-NAME, thrombin and collagen exposure. Interestingly, such effects have been observed during stimulation with agents such as phenylephrine and KCl on L-NAME mediate rats, were damaged by the NOS inhibitor L-NAME. Result : As the result of this study, In group, the anti-apoptosis and necrosis in the cardiovascular system have a potential capacity for prevented, protected and treating the diseases of cardiovascular system, against the necrosis of rat and ECV 304 cells with Caspase 3 and calpain expression by L-NAME is promoted. Conclusion : these results demonstrate neuroprotective and memory enhancing effects of ZIBU, suggesting its beneficial actions for the treatment of AD.
