For the characteristics of the concrete using Hwang-Toh aggregate, thermal Insulation capacity test, absorption capacity of heavy metals several test were performed. The study found that the Hwang-Toh concrete could improved the characteristics of conventional normal concrete. The Hwang-Toh concrete shows 67.7% lower thermal conductivity than normal concrete, so it shows good thermal insulation capacity. And the leaching test results showed that 96% of heavy metals such as Pb, Zn, Mn were absorbed by the Hwang-Toh concrete.

세계화의 비판적 고찰과 대안의 모색 : 정치경제학적 접근 Political Economy Approach

황준성 한독경상학회 2003 經商論叢 Vol.21 No.2

20세기 냉전체제 종식과 함께 세계의 주된 관심은 이념구현에서 경제번영으로 바뀌었다. 이러한 변화의 가장 주요한 원리는 세계화(Globalization)라는 이데올로기이다. 본 연구는 '세계화 이데올로기가 세계경제를 번영시키는 유일한 패러다임인가, 아니면 다른 대안적 패러다임의 모색이 필요한가'라는 질문에 대한 해답을 찾는데 그 목적이 있다. 세계화를 지지하는 입장에서는 세계화가 자유로운 시장의 교환을 보장함으로써 개별 경제주체의 이익의 극대화, 높은 효율을 통한 수익의 증가, 소비자 만족 증대 등을 통해 궁극적으로 세계경제 전체를 번영시킨다는 소위 positive-sum game으로 이해하고 있다. 반면 세계화를 부정적으로 보는 입장에서는 세계화가 매우 효율적인 자본시장만을 보장함으로써 세계경제를 더욱 불평등하게 하고, 세계경제의 불안정성을 초래하는 zero-sum game으로 평가하고 있다. 본 연구는 한국을 비롯한 세계 대부분의 국가들이 세계화를 선택의 문제가 아니라, 생존의 전략으로 인식하는 현 상황에서 세계화가 초래하는 부정적 영향을 고찰하고, 그에 대응하기 위한 적절한 대안을 모색한다. 세계화는 거스를 수 없는 대세이다. 문제는 어떻게 세계화를 저지하느냐 하는 것이 아니라 어떻게 세계화를 모든 국가가 win-win 하는 게임으로 작동 시킬 것인가 하는 것이다. 이러한 관점에서 한국은 세계화에 따른 비용을 최소화하고, 세계화 속에 필요한 국제경쟁력을 확보하여 지속적인 경제발전을 추진하는 새로운 패러다임을 정립하고 이에 따른 세계화 전략을 수립해야 한다. Globalization has received a great deal of attention recently, both in the scholarly and journalistic press. globalization is defined as the ongoing process of international economic integration, through which various forms of interactions between national economies are increasing. The primary indicator of the extend of globalization is the proportion of national economies that is accounted for by international economic transactions, including primarily international flows of trade, capital, and labour. Globalization is very controversial. optimists believe that globalization has opened the way variously to worldwide liberal democracy, huge efficiency gains, enhanced consumer satisfaction, enabled greater intercultural communication. Eventually optimists understand the globalization as a positive-sum game. In contrast, critics have faulted contemporary globalization for in one way and another impeding democracy, imposing a post-colonial imperialism, deepening social inequalities, suppressing vulnerable cultures, massively aggravating ecological degradation. With such claims and counterclaims, the stakes in globalization debates are clearly high. The arguments can understandably become passionate. Especially this paper will analyse the negative effects of globalization. And it attempts to seek after it's alternatives.

Background and Objectives: We previously reported that, compared with standard cardiopulmonary resuscitation(S-CPR), better hemodynamic effects could be achieved by simultaneous sterno-thoracic cardiopulmonary resuscitation(SST-CPR) in which we compressed the sternum and constricted the thorax circumferentially during the systolic period by using a device. This study was designed to assess whether SST-CPR, compared with S-CPR, improve the survival rate of dogs with cardiac arrest. Subjects and methods: Twenty-five mongrel dogs(19∼31㎏) were enrolled in this study. After four minutes of ventricular fibrillation induced by an AC current, animals were randomized to resuscitate with either S-CPR(n=13) or SST-CPR(n=12). Epinephrine(1 ㎎) was injected into the right atrium every three minutes after the beginning of CPR. Defibrillation was attempted after 6 minutes of CPR. Standard advanced cardiac life support was started if defibrillation was not successful. Results: SST-CPR resulted in significantly(p<0.001) higher systolic arterial pressure(91±47 vs 47±24 ㎜ Hg), diastolic pressure(43±24 vs 17±10 ㎜ Hg), coronary perfusion pressure(35±25 vs 13±9㎜ Hg), and end tidal CO2 tension(9±4 vs 3±2 ㎜ Hg). Two of 13 animals(15 %) resuscitated with S-CPR and six of 12 animals(50%) resuscitated with SST-CPR survived until 12 hours after cardiac arrest(p<0.05). Donclusion: SST-CPR, compared with S-CPR, improves the short-term survival rate in canine cardiac arrest.

청피홍심무우를 재료로 A. rhizogenes A₄균주를 접종하여 hairy root를 유도하였으며 유도된 hairy root는 paper electrophoresis를 통하여 mannopine과 agropine이 검출되어 형질전환 되었음을 확인하였다. Hairy root는 MS의 기본염을 1/2로 희석시킨 1/2 MS, sucrose 3%, pH 5.2로 조성된 배지에서 최적인 성장을 보였다. 유도된 hairy root는 각 strain사이에 색소능에 다소간의 차이를 보였으며 2, 4-D kinetin의 적절한 조합의 처리구에서는 탈분화와 더불어 색소가 형성되었고, 그 중 2, 4-D와 kinetin을 각각 1 ppm, 5 ppm 처리하였을 때 최대 색소능을 보였다. hairy root의 탈분화시 형성되는 색소는 원 식물 뿌리의 주 색소인 pelargonidin 계열의 색소로 추정되며 총 색소량은 49mg/100g(F.W.)로 잠정 계산되었다. Hairy root induced following inoculation of the root disc and plantlet fragment of R. sativus Var Chungpihongsim with A. rhizogenes A₄. The hairy root contained agropine and mannopine. Medium contained 1/2 MS salt, sucrose 3%, pH 5.2 was optimized to growth of hairy root. Depending on the hairy root line, the level of pigment in hairy root varied somewhat . When 2, 4-D and kinetin were added in hairy root, the synthesis of pigment induced with deorganization of hairy root. Especially, addition of 2, 4-D 1 ppm and kinetin 5 ppm showed the maximum synthesis of pigment. Compared with anthocyanin extract of mature root three pigments were assumed to acylated pelargonin. The content of anthocyanin in these sample was 49mg/100(F.W.).

경골 Pilon 골절의 수술적 치료 : 제한적 내고정술을 겸한 외고정술과 관혈적 정복 및 내고정술의 비교 Comparison of Limited Open Reduction and External Fixation with Open Reduction and Internal Fixation

황득수,양준영,정제택 충남대학교 의과대학 지역사회의학연구소 1998 충남의대잡지 Vol.25 No.2

The pilon fracture result from axial compression and rotational forces causing variable degrees of metaphyseal disruption, articular damage and malleolar displacement. It's managements are closed reduction and plaster immobilization, skeletal traction, fibular stabilization alone, limited open reduction and external fixation, open reduction and internal fixation, primary arthrodesis, and even immediate amputation. Recently limited open reduction and external fixation has been proved to provide good clinical results for the severely comminuted or open pilon fractures. Authors reviewed eighteen cases of the pilon fractures from March 1991 to February 1997. Among them eight cases were treated with limited open reduction and external fixation, and ten cases were treated with open reduction and internal fixation. In conclusion, limited open reduction and external fixation has shown better results than open reduction and internal fixation in severely comminuted or open pilon fractures for wound healing and preventing of other complications.

'거주지 기준 고교입학제한 정책'에 대한 법적 고찰 : 학교선택권을 중심으로 Centered for the right of school choice

황준성 연세대학교 교육연구소 2002 연세 교육연구 Vol.15 No.1

'학교선택권'은 우리 헌법이 명시하고 있는 ‘교육기본권’의 핵심적 내용임과 아울러 헌법 이전의 자연법으로부터 유래되는 ‘기본적 인권으로서의 교육권’을 실질적으로 보장하고 실현하기 위한 중요한 기재의 하나이다. 그러나 ‘고교평준화정책’과 함께 우리나라 고등학교 진학제도의 근간을 이루고 있는 ‘거주지기준 고교입학제한 정책’은 거주지라는 부모의 사회·경제적 지위가 개입되는 요소에 의하여 국민의 학교선택권을 심각하게 제한하고 있다. 이와 관련하여 헌법재판소는 지난 1995년 관련 판례에서 고교진학제도의 근거법령에 대하여 합헌 판결을 내린 바 있으나, 이는 다시금 재고되어야 한다. 거주지 기준의 고교입학제한 정책은 학교선택권과 함께 교육기회의 실질적 평등을 침해하는 것이며, 기본권제한의 한계로 일반적으로 논의되는 목적상의 한계, 형식상의 한계, 내용상의 한계, 방법상의 한계를 모두 일탈한 것이기 때문이다. The purpose of this article is to investigate the legitimacy and constitutional compatibility of the policy which restricts peoples' highschool entrance on the basis of residence. For this purpose, this paper analyzes current Korean highschool admission system, clarifies the origin and meaning of the right to choose the school where people or there children will go, and decompose the Constitutional Court's ruling concerned. Finding results are as follow. First, the main point of the current choice of our high schools and entrance system for schools is based on residence related with the social, economical backgrounds of students' parents rather than their abilities to study. And especially in academic high schoolㄴ, the allocation system by drawing lots which is based on students' school district puts severe restriction on the right to choose the school of people in Korea. Secondly, the right to choose the school is a kind of essential content of both "The Right of Education in Constitution" and "Educational Human Right Guaranteed with Natural Law" before constitution. Also it means the right to enter a school in which students want to be educated and learn what they want. In addition, it should not be trespassed by a country or any disinterested parties. Thirdly, Constitutional Court said that "Education Law's enforcement ordinance", which is fundamentals of the entrance system of schools at that time, doesn't violate Constitution, even though the right to choose the school is admitted as "the right in Constitution" in the ruling concerned[91헌마204]. However, the restrictive policy of high school entrance, of which standard is students' living places, and the relating laws to it are invading the right to choose the school and the actual equality of educational opportunities as well. Moreover, it is logically right that this is against Constitution because the limitations of the purpose, the formality, the content and the manner are deviated completely. In conclusion, the policy of high school entrance of which standard is students' living places never fail to be abolished because it trespasses on the right to choose the school severely, and the current entrance system of high schools should be investigated again entirely, in order to protect the right to choose the school and raise the educational power of local schools with much induction of their competitions.

한국산 부산입술대고둥(Euphaedusa fusaniana)의 아이소자임 변이

황보학,이준상,조등현 江原大學校 附設 環境硏究所 1994 環境硏究 Vol.11 No.-

Electrophoretic variations in isozymes encoded by 16 loci were studied to estimate genetic variation and to assess phyletic relationships, and biogeographic pattern of distribution of the Euphaedusa fusaniana collected from Sehwa, Aeweol, Samchuck, Tongdosa, Gernundo, and Y?su areas in Korea was discussed with respect to the isozyme variation. The 180 apecimens were examined. Means of allele per locus(?) and polymorphism(?) were 1.528 and 45.5%, respectively and hetrozygosity (?_(D)) was 0.205. Samchuck population showed lower mean value of allele per locus(?=1.46). Higher polymorphism(P=57.14%) was observed among Tongdosa popualtion. Aeweol population showed slightly lower genetic variation (H_(D)=0.15) than others. Average genetic similarities(?) among the six populations was 0.716 Aeweol and Samchuck populations were genetically closer(S=0.903) than others. However the S value between Y?su and Samchuch populations was low(S=0.562). Average genetic distance(?) among the 6populations were 0.267. Both Aeweol and Samchuck populations have closer genetic distance (D=0.067). Genetic distance pattern was similar to genetic similarity pattern.
