To investigate the effect of hyperoxia on EKG findings and to evaluate the applicability of EKG as noninvasive monitoring index of oxygen toxicity, 38 rabbits were continuously exposed to 6 different conditions-3 hyperbaric oxygenations (HBO-2.5, 3.5 and 5ATA, 100% $O_2$), normobaric oxygenation (NBO,100% $O_2$), hyperbaric aeration (HBA-5ATA, 21% $O_2$) and normobaric aeration (NBA, 21% $O_2$)-for 120 minutes and their EKG and time to dyspnea and convulsion were recorded. Dyspnea and death were observed in exposure conditions of HBO-3.5 and HBO-5 (Positive rate of dyspnea 10%, 100%, death : 10%, 25%, respectively) only, and convulsion in 4 oxygenation groups (NBO;20%, HBO-2.5;20%, HBO-3.5;20%, HBO-5;88%). Abnormal EKG findings included arrhythmia and ST-T changes and the incidences was increasing with doses(partial pressure of oxygen). In addition to EKG change, findings observed during exposure were dyspnea and convulsion in the order of appearance and when non specific ST-T change was accepted as positive(abnormal) finding, the frequency of abnormal EKG was statistically significant(p<0.01), but when it was excluded from positive results, the frequency of EKG change was not significant(p>0.05). These results suggest that the effect of hyperoxia on heart is myocardial ischemia and arrhythmia, that oxygenation more than 3.5ATA causes myocardial damage in 120 minutes exposure, and that EKG is valuable as monitoring index of oxygen toxicity.

The effects of aerobic exercises and/or supplementation of kimchi on changes of the body composition and plasma lipids of obese middle school girls were studied. Thirty eight girls, 28 obese girls and 10 normal weighed girls, were paricipated. Among obese girls, 8 were assigned to exercise group (FG) 12 were grouped as kimchi group (KG) , and 8 were asked to practice excercise and to take kimchi simultaneously(excercise kimchi group, EKG). Ten girls whose weight is normal asked to remain o their own diet during 6 weeks of experiment (control group, CG)/ EG practiced jogging and rope-jumping for 60 minutes four times a week and KG took 3 g of freeze-dried kimchi packed in a 500 mg capsule daily which is equivalent to 30 g of fresh kimchi, EKC, EG and KG showed beneficial effects on changes of the body composition and plasma lipids compared to those of CG, EG showed greater effect than KG in reducing body fat resulted decrease in BMI, fat mas,. abdominal fat, and triglyceride concentration and increase in HDL-cholesterol. KG seemed to have greater effect on lowering plasma cholesterol and LDL-cholesterol than EG/ But the greatest effects in terms of reduction in weight, BMI fat mass, abdominal fat, total cholesterol, LDL-cholesterol, triglyceride, and increase in HDL-cholesterol were observed from EKG. These results indicate that kimchi supplemenation while practicing excercise might improve the obese state by reducing body fat content as well as reducing plasma lipids.

난간의 각 구성요소는 설치장소 및 용도에 따라 여러 설치 관련규정에 의해서 규제되어 있는데 이 규정은 난간의 높이에 대한 규정으로, 이러한 규제된 난간의 요소 중 하나인 난간 높이와 실지 소비자들이 느끼는 심리적 안정성이 일치하는가에 대한 여부는 여전히 의문으로 남아있다. 건물의 옥상에 설치된 난간에 대해서 난간의 높이가 아닌 다른 어떠한 구성요소가 실지로 소비자들에게 조형적 안정감을 주는지에 대한 부분은 연구가 상당히 미흡하다고 생각한다. 본 연구는 부산에 위치한 초등학교를 대상으로 4층 이상의 고층구조물에 설치되어 있는 난간을 범주로 하여 설문조사를 실시하고, 난간이 설치되어 있는 현장에서는 EKG(심전도 테스트)를 시행, 사용자들이 기존에 인지하고 있는 난간에 대한 느낌과 현장에서 실제로 느끼는 조형적 측면의 심리적 안정감 및 다른 요소를 분석하여 사용자가 안정감을 가질 수 있는 난간디자인에 필요한 구성요소를 발견하는 것이 본 연구의 목적이다. 또한 기존에 사용하고 있는 난간 설치의 규정의 정당성 여부를 고찰 및 재조명하여 사용자의 심리적 안정성을 충족시키는 가에 대한 자료 제시를 목적으로 한다.

Objective : The heart diseases are known as a major cause of sudden death, as well as a cause of poor life-quality of school-age children. But there have been few mass screening of heart diseases in these children in Korea. This study was done to estimate the prevalence of heart diseases of these population. Methods : We screened all elementary students(grade 1) in 12 cities and 16 counties(Gun) in Kyonggi province from 1992 to 1955. The first screening was done by auscultation of doctors and simultaneously by checking using 'auto-interpreter of EKG-cardiac sound' (Fukuda Densi ECP 50A). We conducted luther examinations to whom classified as being abnormal condition in first screening, by using EKG, chest x-ray, doppler echocardiograpy(if needed). Results : The total number of examined students was 161,308(92% of the population), the male were 83,238 and female were 78,070. The congenital heart diseases(CHD) patients were 290(18 per 10,000) - male 155(18.6 per 10,000) and female 135(17.3 per 10,000). The most frequent disease was ventricula septal defect(VSD, 45.5%), Atrial septal defect(ASD, 14.8%), Tetralogy of Follot(TOF, 11.7%), and Patent Dutus Arteriosis(PDA, 7.6%) in order. In female, the order was VSD(48.1%), ASD(13.3%), TOF(11.1%), and PDA(10.4%). The total number of EKG abnormality were 433(62.7 per 10,000) among 69,056 screened children in 1995. The complete right bundle branch block(CRBBB) and paroxymal ventricular contraction(PVC) were frequent(26.6%, 26.3% in each), and incomplete right bunddle branch block(IRBBB, 14.6%), paroxymal atrial contraction(PAC, 6.7%), abnormal Q(5.8%), Wolf-Pakinson-White syndrom (5.5%) in order. In female, the most frequent abnormality was PVC(29.8%), and CRBBB(19.9%) in order. Conclusion : We could present the stable prevalence of the rare heart disease. The prevalence of congenital heart diseases was 18.0 per 10,000 and of EKG abnormality was 62.7 per 10,000 among school children.

The ECG which used for this paper, is analysis result from alogrisms of arrythmia, and we have studied that how we could certain Cold(寒 )type or Heat(熱) type and that Deficiency(虛) type or Excess(實)type of organs from various special diseases, and we obtained like these results. 1. we depend on our examination about Pulse(脈) because we can't discriminate arrythmia using EKG analysis instruments. 2. We obtained that Cold(寒) type diseases had wave that prolonged above normal baseline and ST wave which had downward aptitude. 3. We obtained that Heat(熱) type diseases had the fibrillation which had shortend wave that compare to normal and had downward aptitude or negative aptitude. 4. We obtained that Respiratory system (肺) diseases had wave that is within normal or is short of normal range and had much fluctuation in potential difference or trans on P wave. 5. The character of EKG which presented about diseases of gastric systems is prolonged above narmal range of wave, and the EKG had represented mixed wave with Heat(熱) type when accompany inflammatory in gastric system. 6. The wave of Blood Stasis(瘀血) type had upward aptitude of QRS wave, and the wave of anemia or blood loss type(少血 ) had downward aptitude of QRS wave, the wave which had both Cold(寒) and Heat (熱) represented mixed waves. 7. The Knotted Pulse(結脈) and Intermittent Pulse(代脈) is corresponded with sinus brady cardia, and the Swift Pulsle(疾脈) is corresponded with fibrillation. 8. We pay attention to the relations of formations about pressures pulse from formations of EMD( electromechanical dissociation ). From these results, we will have to study about EKG which using in tests of change of Parkinsons disease.
