尹馨培,黃迪駿 고려대학교 의과대학 1991 고려대 의대 잡지 Vol.28 No.1

In order to classify the type of the urine by using of the inhibition effect of Sophola japonica which acts as pan-phytagglutinin, to human red blood cells. Compared the relationship between the type of urine classified in this study and the types of other specimens which are already proven by other methods. There are two types of human urine : one with sub-stances that inhibit the agglutination of Sophola Japonica extract to human red blood cells and the other without those substances. Among 300 human urine specimens involved In the present study, 12% (36 specimens )were shown to have those inhibition substances in their urine. The types of urine classified in this study showed no relationship with those classified by the Agastache rugosa extract. Neither the known type of saliva nor the type of experimented by the Sophola japonica extract had any relationship with the type of urine determined in this study. No significant relationship could be found between the various type of blood and Serum types such as ABO, MN, H, Cl, IPO, NPO, ICO, NCO and the urine type.

Most clinicians agree that the group of disorders called schizophrenia is heterogeneous. Since Kraepelin described dementia praecox, various attempts have been taken to subdivide schizophrenia into several homogeneous subtypes. Recently some investigatiors were interested in the division of schizophrenia by use of positive & negative symptomatology that Hughlings-Jackson had tried. Crow especially hypothesized that there were some differences between the tow prominent symptoms(negative & positive) in respect of premorbid adjustment, response to neuroleptic therapy and underling pathologic process etc. But this hypothesis remains largely untested. Using Andreasen & Olsen's criteria for negative, positive and mixed schizophrenia, we subdivided a consecutive sample of 67 schizophrenic patients into 3 subtypes (negative 21, positive 23, mixed 23). We then evaluated some characteristic aspects among these 3 subtypes. The results are as follow : 1) There was s significant difference in mean age among the three subtypes. In the negative group, the mean age was most high and this was followed by the positive group(p<0.05). 2) There was a significant difference in the duration of education among the three subtypes. In the negative group, the duration of education was least and this was followed by the positive group(p<0.05). 3) There was a significant difference in premorbid adjustment among the three subtypes. The level of premorbid adjustmentwas lowest in the negative group and this was followed by the positive group.(p<0.005). 4) There was a significant difference in the number of previous hospitalizations among the three subtypes. In the negative group, the number of hospitalizations was lowest and this was followed by the positive group.(p<0.005). 5) The experience of previous modern psychiatric treatment was more reare in the negative group and this was followed by the positive group.(p<0.05). 6) The score of mini mental status for evaluation of cognitive function was significantly lower in the negative group and this was followed by the positive group.(p<0.001). 7) The scores of the BPRS for evaluation of psychotic symptoms at the times of admission and 4 weeks later were significantly most high in the positive group and this was followed by the mixied group (p<0.05, respectively). The therapeutic response rated on the BPRS after 4 weeks, was significantly prominent in the positive & mixed groups(p<0.05, respectively), but not in the negative group. 8) Besides these, there were no significant differences in occupation, onset of age, duration of illness and family history among the three subtypes. .

We study the methods to calculate the bound-to-continuum transition amplitudes in a biased GaAs/AlGaAs quantum well detector structure. First we apply the complex energy method to evaluate the energy levels of meta-stable states. We also present how the coefficients of the travelling waves change with the complex value of energy. Transition amplitudes to each continuous scattering states are also calculated. The transition peaks evaluated agree well with the energy levels of the meta-stable states found using the complex energy method.

유럽통합의 공법적 영향에 관한 연구 : 유럽통합이 독일행정법에 미친 영향을 중심으로

홍준형 서울대학교 국제지역원 2001 국제지역연구 Vol.10 No.4

유럽통합의 진전에 따라 진행된 법의 유럽화(Europ"isierung) 현상은 다소 뒤늦게 일반행정법분야에서도 시작되었다. 유럽행정법의 국제화를 가져온 계기는 유럽공동체 소속기관들의 실무를 통해 주어졌다. 그러나 유럽사법재판소(EuGH)의 판례와 문헌에서 단일한 유럽행정법의 요소들로 추상화되었던 회원국들의 법체계들로부터 단일한 공동체 고유의 행정법이 생성되는 과정은 10여 년 전부터는 법통일의 그것과는 상반된 방향으로 전개되고 있다. 그 결과 유럽행정법이란 개념을 유럽공동체기관들을 통한 단일한 행정법이라는 의미로는 더 이상 사용하기 어렵게 되었고, 오히려 공동체관련 사안에 적용가능한 개별국가의 행정법을 포함하는 의미로 외연이 확대되게 되었다. 역사적 근원을 존중하여 유럽공통의 행정법(gemeineuropa"isches Verwaltungsrecht)을 이야기할 경우 그것은 이 두 가지의 발전방향을 뜻하는 것으로 이해된다. 법리적 측면에서 유럽법의 영향은 직접적 효력(Direktwirkung)과 법원리적 계수(prinizipiengeleitete Rezeption)라는 두 가지 상이한 경로를 통해 독일법에 영향을 미치고 있다. 유럽통합이 독일행정법에 미친 영향을 이해하지 않고서는 더 이상 독일 행정법의 형성 및 작동원리를 정확하게 파악할 수 없게 되었다고 해도 지나친 말은 아니다. 특히 독일의 국내행정법과 함께 독일에서 국내법과 동등하게 적용되는 또 다른 유럽행정법의 형성과 규범적 내용(Hypothese von der Zweiteilung des o"ffentlichen Rechts)을 이해하는 것은 독일행정법으로부터 적지 않은 비교법적 자양분을 공급받아온 우리나라 행정법의 이론과 실천에 있어 매우 중요한 의미를 가진다. 유럽행정법의 영향을 제대로 반영하지 않은 독일행정법에 대한 비교법적 참조는 이제 더 이상 적실성을 상실하게 된 것이다. 이러한 관점에서 유럽행정법의 발전이 독일행정법에 끼친 영향을 법형식론(법원론과 행위형식론을 포함), 주관적 공권론, 판단여지 및 재량 이론, 행정규칙론 등의 문제영역에 초점을 맞추어 분석, 평가하였다. Impact of the European Integration on national public laws of member states truns out to be unique and remarkable, which this article analyzes with its influence upon the German Administrative Law. European Administrative Law, which emerged originally as a discrete body of those special laws governing the organs of the European Community encompasses now broader elements like public laws of each member state to be applied to the Community relevant issues and cases as well as those public laws formed by various instances of the European Union like the Commission, Court of Justice of the European Communities etc. It exercises great influence upon the German administrative law primarily through the direct effect (Direktwirkung) and principle-guided reception of european laws and legal doctrines (prinzipiengeleitete Rezeption). At this moment it is almost impossible to understand the German administrative law without comprehending the influence of the European Integration upon it. So long as German administrative law plays a role as a reference model for Korean Administrative law, still in many ways, the changes in its legal doctrines and theories brought about by the European integration need to be correctly reviewed and analyzed with its current statuts of development. This article reviews those changes, especially in those legal doctrines and theories regarding legal forms of administrative activity (Rechtsformenlehre: including source of law and forms of administrative acts: Rechtsquellenlehre αnd Handlungsformenlehre), subjective public rights (subjective o˝ffentliche Rechte), administrative discretion (Beurteilungsspielraum und Ermessen) and Administrative Guidelines and Standards (Verwaltungsvorschriten).

This study examined the physiological and histological changes in Sprague-Dawley rats with induced hypertension by chronic treatment of NG-nitro-L-arginine methyl ester(L-NAME), nitric oxide synthesis inhibitor. Systolic blood pressure of L-NAME treatement experimental group was significantly higher compared with untreated control group by 28.5%(44.2mmHg)(p<0.001). Changing rates on systolic blood pressure of L-NAME treated groups according to during L-NAME treatment period were significantly higher than control groups by 16.1% in 2weeks, 15.1% in 4weeks(p<0.05), 29.1% in 6weeks(p<0.01) and 28.5%(p<0.001). However, heart rate and body weight did all not significant differ between L-NAME treated group and control group, between L-NAME posttreated rats and pretreated rats. Systolic blood pressure had each low correlation with heart rate and body weight. In conclusion, chronic inhibition of nitric oxide by L-NAME treatment had significant effect on systolic blood pressure, but not affect on heart rate and body weight. Thus, this study suggested that nitric oxide had important role to control for blood pressure and to modulation for function of organs associated with blood pressure.

This study investigated mean airborne CO concention of 15 workplaces, suspected of CO exposure and conducted self-reported questionnaire completion and indirect COHb concentration measure using Micro II Smokerlyzer to healthy 702 adult subjects from 1999 May to 1999 September in order to find a relation of CO exposure and occupational factors, socioeconomic factors, and health related behaviors and confirm the related conditions in the screening test for CO exposure. The results of this study were summarized as follows : 1. In the CO exposed and non exposed group, COHb concentrations of the smokers were 2.55±0.96% and 2.21±0.97% and that got a statistically significant difference, There were not statistically significant differences in the age and total smoking index. Passed times after the last smoking, Working time/day, and working duration were statistically significant difference (p〈0.05). 2. In the CO exposed and non exposed group, COHb concentrations of non-smoking group were 0.94±0.35% and 0.68±0.47% and that got a statistically significant difference. There were not statistically significant differences in the age and working duration but Working time/day was a statistically significant difference(p〈0.05). 3. In the CO exposed group, r-square of multiple regression of the smokers was 38.5 % and passed time after the last smoking, working time/day, and job category were statistically significant differences (p〈0.05). And r-square in the CO non-exposed group was 38.3 % and age, passed time after the last smoking, and total smoking index were statistically significant difference. 4. In the CO exposed group, r-square of multiple repression of the non-smokers was 66.3% and job category and airborne CO concentration were statistically significant differences(p〈0.05). But r-square of non-smokers in the CO non-exposed group was 1.0% and there was not a statistically significant difference(p〈0.05). 5. In the smokers of CO exposed and non exposed groups, relation of COHb concentration and passed time after the last smoking was expressed as exponential function, Y = 2.9182e-0.0083x and r-square of this function was 37.4%. Therefore it was more than 150 minutes that passed time after the last smoking was when COHb concentrations were measured as less than 1%. In conclusion, variable, that was statistically significant to COHb concentraion in the both CO exposed and non-exposed smokers, was a passed time after the last smoking. We suggest that you have to restrict the smoking of smokers at least 150 minutes in the exposed and non exposed group before COHb concentration measure in order to exclude smoking effects

We examined adult patient l,000cases be questionable as coronary artery disease by treadmill exercise test, and the following results were obtained. 1. Total positive rate was 10.1%, and it was significantly differ between male and female(p<.05), and it was significantly differ as increase of age(p<.00l). 2. The stop reasons of treadmill exercise test were significantly differ between male and female, because of chest pain of female higher than male (p<.00l), and it was significantly differ as increase of age(p<.05), and it was significantly differ between positive and negative groups, because of most frequent stop reaseons were chest pain in the positive group and dyspnea in the negative group(p<.001). 3. Average maximum workload level of male was significantly higher than female(p<.001), and it was significantly decresed as increase of age(p<.001), and it was significantly differ between the total positive groups(81±2.7METS) and negative groups(9.3±2.4METS). And performance degree of maximum workload level in the positive group was most frequent as stage 3(42.6%). 4. Average maximum heart rate was not significantly differ between sexual groups in the positive group, but it was significantly differ between sexual groups in the negative groups(p<.001), and it was significantly decrease-as increase of age(p<.001), and it was differ between the total positive groups(158.5±23.0bpm) and negative groups(162.7±20.5bpm)(p<.0.1). 5. The reaching level of target maximum heart rate was not significantly differ as between sexual groups, as between age groups in the positive groups, but it was significantly differ in the negative groups, and it was not significantly differ between the total positive groups (93.2±l1.6%) and negative groups (94.2.±l0.l%). 6. Decreased cases of systolic blood pressure were 28cases in the toal positive groups, and most decreased as stage 2, and most frequently decreased level was lower than l0mmHg. 7. Decreased cases of ST segment were 93cases in the total positive groups, most frequently decreased level was higher than 1 mm under the baseline.
