최경임,이진태,안봉전,최은영,박찬익 경산대학교 생명자원개발연구소 2002 생명자원과 산업 Vol.6 No.-

지금까지의 발모관리는 의학적인 차원에서 원형탈모, 남성형 탈모증 및 약제에 의한 병리학적인 연구가 있었으나 미용적인 관리에 대한 연구가 거의 없었다. 따라서 본 논문에서는 약품을 사용하지 않고 순수한 발모촉진 화장품과 두피관리 프로그램을 중심으로 발모관리를 통해 탈모개선 효과를 비교검토하였다. 탈모자를 여러 그룹으로 선발하고 발모제를 달리 처방하여 모발의 굵기, SEM 촬영, 수분측정, 정상인의 모발상태와 탈모자의 모발상태를 TEM 촬영하여 비교 분석하였다. 먼저 두피관리 전과 후의 수분함량의 차이는 평균 16% 상승하였다. 발두께 비교실험에서는 정상모에 비해 탈모자의 모발이 최대 38.6%가 작은 것으로 나타났으며, 모유두와 모간의 촬영사진에서는 탈모자의 모유두는 덜 발달되어 있었고, 변형된 모유두 형태가 많았다. 전자현미경을 통한 모표피의 SEM촬영에서는 탈모자나 정상모나 표면적으로 큰 차이는 없었다. 오히려 탈모자의 경우에는 모발이 약하고 건강하지 못하기 때문에 화학적인 처방을 하는 염색이나 펌 등을 하지 않아서 모발의 큐티클 층은 정상인의 모발보다 건강한 상태로 보였다. 두피측정에서는 관리 후 A, B, C 군의 비교에서 세 그룹 모두 두피의 현저한 개선효과를 보였다. 육모제를 사용한 A, B, Group과 영양제를 사용하지 않고 스캘링과 관리를 한 C군 모두 발모효과가 있었으며, 두피관리를 전혀 하지 않는 D군은 발모효과나 두피의 개선효과는 전혀 없었다. 전자 현미경을 통한 모발의 단면 촬영에서는 정상모발이 탈모자의 모발보다 피질이 부드럽고 풍성하게 잘 형성되어 있었다. 탈모자의 경우는 매우 심각한 고민거리인데 본 실험의 결과 가장 효과적인 발모 관리는 육모제로 두피의 혈액순환을 도와주고 평소생활에서 Brushing으로 모공이 막히지 않도록 꾸준한 손질을 함으로써 발모 및 두피개선이 될 수 있다는 것을 확인할 수 있었다. Twenty working people from 30s to 50s whose hairs were in the process of losing were selected for this study. They were divided into four groups as A, B, C and D. Their hairs were sampled to compare the thickness of the hairs through a optical microscope. Using hair care products from two marketing companies, once a week, Group A and B were treated scalp scaling and steam treatment during ten minutes. After applying vitamin cream the scalp was examined using a bio-beam every 5 minutes. Group C did not receive any vitamin cream but had the same treatment as A and B. Group D used no vitamin cream and receives no treatment. The results were as follows: In Comparison losing hair surface with healthy hair surface by electronic microscope, losing hair took place when the scalp has keratin or too much fat. After comparing the amount of moisture before and after care by a moisture measurement instrument, the amount of moisture has been outstandingly increased. As a result of observing hair root and hair shaft, hair root appeared to be less developed than healthy hair. These results showed that hair care is need to be constantly research and illuminate with regard to the proper care.

韓國과 西洋體育의 歷史的 考察

崔昌俊,宋銀燮 群山大學校 1984 論文集 Vol.9 No.-

Both in oriental and occidental worlds physical education is so much related with developments of each country from the ancient till the present time. So the study of physical education is going with the study concerns with cultural and civilizational backgrounds. Occidental physical education in chronological order have something to study with oriental physical education, particularly in Korea. The origination of olympic games in Greece is so much related with politics, economics, and military power. We, in Korea, have similar motivations in the origination of physical activities. For example, the celebrations like in Greece, in May and October concerned with planting and harvesting. Dongmaeng, Yunggo, Moochon had some similar celebrations. And these celebrations included some physical activities. So we can find the present physical activities are rooted in such ones in ancient times. And we can find chronical power domonstrations and development in other sides are so much related with rise and fall of the concern in physical activities. I found that similarities between the celebrations of olympia in Greece and those of KokuRyu, Pu Yyu, Yae Ie and Mu cheon in Korean history. These celebrations in Korea is so much closed with military activities. We can see similarities of old Korean countries like Greak celebrations. And such similarties of some have been developed like those of present physical activities. Observing old plays historically ChukKuk played in 3 countries are similar to present soccer, Sael main Koryu Dynasty present ski, Keok gu Harkey resectively. But The traditional sports uttered above are not present in the present Korea, but exists only in the historical backgrounds. If we search and develop the traditional sports games. we can embody ourselves distinctively through our diverise sports games inherited from the ancient times, and contribute those backgrounds to the cultural stream so that we may bloom our own culture to be balanced with cultural factors outside. After coloney of Japan Korean physical activities are So much influened by those of America. But I think developing distinctive national physical activities is important burden to the enhancning of Korean physical education.

崔宗煐,李定均,徐維憲,朴贊雄 大韓神經精神醫學會 1981 신경정신의학 Vol.20 No.1

Plasma chlorpromazine level and some aspects of the clinical significane were studied with 20 schizophrenics. The results were as follows; The (so-called) steady state of plasma chlorpromanzine level was arrived at about 12th day of the drug administration in a dose of 300mg/day on a fixed maintenane regimen. Thereafter the level tended to decline slightly. After arriving at the steady state, a significant positive correlation was observed between the plasma level and the dose of the drug, both in intra-and interpatient comparisons (r=+0.5855, p<0.025). On a fixed chlopromazine dosage, the plasma levels showed marked interpatient differences both before and after the initial day of the steady state, though the differences were more marked before the period of steady state. No significant positive correlation could be identified between the plasma level and the drug side reaction, though 78% of the observed side reactions were positively related with the plasma level of 1.5 mcg/ml or above. And again, significant positive correlation was not observed between the plasma level and the clinical improvement. So-called 'therapeutic window' was considerably wide ranging between 0.5 to 2.45 mcg/ml of the plasma level.

A Study on the Oxidation of Cobalt Film

崔燦有 東國大學校 1975 論文集 Vol.14 No.-

The kinetics of the oxidation of Cobalt films have been studied using quartz microbalance from 600℃ to 900℃ under various oxygen pressures. The oxidations followed the parabolic rate law in all caces and the parabolic rate constant varied apporximately from 1.64×10^-12 to 1.11×10^-11 (g/cm^2)^2 sec^-1 The activation energies calculated from the plots of log K_p vs. 1/T varied between 0.08 eV and 0.3 eV in the above conditions. The 1/n values obtained from the plots of log K_p vs log Po_2 (or log K_p=1/n log Po_2) are about 1/5 to 1/3.7. The mechanism for the oxidation of the Cobalt film is discussed in accordance with other mechanisms such as nonstoichiometric mechanism, diffusion mechanism, and conduction mechanism, etc.

急性 Barbiturate中毒症의 臨床的硏究 : 第2編 Electrocardiogram 所見에 대한 觀察 (Ⅱ) Observations Electrocardiograms with Reference to the Alteration in Serum Transaminase, Serum Amylase, Coma & Liver function Tests

崔燦柱 고려대학교 의과대학 1964 고려대 의대 잡지 Vol.1 No.1

In cases of acute barbiturate poisoning, studies on the ECG changes with references to the alteration in serum transarninase and serum amylase are absent in the literatures, though a few studies have been reported on the ECG changes. So the author investigated ECG findings in 30 cases of acute barbiturate poisoning selected at random, with reference to the change of serum transaninase, serum amylase, grade and duration of coma and liver fution tests. Of the 30 patients, there were 9 males and 21 females ranging in age from 16 to 59 years. The degree of unconsciousness were graded I-V according to Reed, et al. There were 3 cases in grade I, 4 in grade Ⅱ, 10 in grade Ⅲ, 6 in grade Ⅳ and 7 in grade Ⅴ. The duration of coma was 6 to 181 hr. with the average being 37 hr. The serum transaminase (SGOT, SGPT) was determined by the Sigma-Frankel method and the serum amylase by the Somogyi's method. Six liver function tests were performed; serum total protein, A/G ratio, C.C.F., T.T.T., alkaline phosphatase and serum total bilirubin. The results were as follows: 1) Six varieties of ECG changes were regarded abnormal: sinus tachycardia, arrhythmia, prolongation of QT interval, depression of ST segment and T wave changes (flattening, biphasic and inversion). 2)Sinus tachycardia was observed in 43.3% of the cases and the majority were associated with depression of ST segment or T wave changes. They usually lasted for a day or so, but occasionally for 2 to 5 days. In some cases the appearance of depressed S-T segment and T wave changes was heralded by sinus tachycardia. 3) Arrhythmia was seen in 6.6% of the cases. In one case tachycardia developed into auricular fibrillation and in another case intraventricular conduction defect was suspected. 4) Prolongation of QT interval was noted in 13.3% of the cases. It appeared earlier than other ECG abnormalities and returned to normal 1∼2 days later. All cases were with abnormalities of S-T segment (2 of elevation and 2 of depression). 5) In 10% of the cases, elevation of ST segment, more than 1 mm. in L₁-L₃ and V₁-V_(6) was observed. Usually they appeared on the 1st day and returned to normal on the following day. 6) Depression of S-T segment, more than 1 mm. in L₁-L₃ and V₁-V_(6) was noted in 36.3%, lasting for 1 to 3 days. In all cases such depression appeared in combination with T wave changes or some of the other ECG abnormalities such as sinus tachycardia, prolongation of QT interval or arrhythmia. 7) In 33.3% of the cases, T wave changes (flattening, biphasic or inversion) were encountered in L₁,L₂ and V₃-V_(6)They appeared with depressed S-T segment in most cases. In only one case T wave change only occured. 8) Combined depressed S-T segment and T wave changes were observed in 30% of the patients, usually coma of higher grade. 9 ) Among the ECG changes, the elevation of the ST segment was the earliest in onset. It was encountered on the first hospital day in all cases. Prolongation of QT interval and sinus tachycardia were observed exclusively on the first or 2nd hospital day, while the depressed S-T segment and T wave changes appeared later on the 3rd day in some cases of coma of longer duration. The ECG changes found in later period of the poisoning were mostIy depression of S-T segment or T wave changes. 10) The incidence of the ECG changes, particularly, depression of the S-T segment, T wave changes or arrhythmia, were higher in the group of grade IV-V than in the group of grade Ⅰ-Ⅲ. While the ECG changes in former group were as much as 53.8% in sinus tachycardia, 61.5% in depression of S-T segment, 53.8% in T wave changes, 53.8% in depression of S-T segment plus T wave change and 23% in prolongation of QT interval, it was only 35% in sinus tachycardia, 17.6% in depression of S-T segment, 17.6% in T wave changes, 11.7% in depression of S-T segment plus T wave changes, and 5.8% in prolongation of QT interval in latter group. There was no relationship between elevation of S-T segment and grade of coma in the author's series. 11) Among the average duration of coma in each group of the ECG changes, the group of depressed S-T segment was the longest. The group of depressed S-T segment plus T wave changes and the group of T wave changes were the next in duration in average. In the group of sinus tachycardia, elevated S-T segment and prolongation of QT interval, the average duration was much shorter but stilI longer than the normal ECG group. Thus some relationship seemed to be indicated between the ECG abnormalities and the duration of coma. 12) Among the average value of SGOT and SGPT in each group of the abnormal ECG cases, the highest value was noted in the group of T wave changes. Another three groups, sinus tachycardia, depression of S-T segment plus T wave changes and depression of S-T segment, were lower than the group of T wave changes with similar abnormal levels. The average value of serum amylase was highest in the group of S-T segment depression plus T wave changes. 13) Cases of ECG abnormalities, particularly of depressed S-T segment and T wave changes, were tend to b e associated with abnormalities in many type of liver function tests. 14) As the causes of the ECG changes in acute barbiturate poisoning not only the myocardial anoxia, possibly of importance, but a direct barbiturate effects on cardiae muscels as well, possibly minor in role, are suggested.
