Nowadays, much attention is being paid to topic map - a kind of searching method based on meanings - for a solution which helps people manage and integrate huge amount of technical information and retrieve correct ones fast and effectively. In order to achieve win-win cooperations between the large enterprises and SMEs (Small and Medium Enterprises), engineering collaborative hub was developed and lots of CAE service - injection-mold flow analysis - were conducted. This paper proposed the integrated KMS(Knowledge Management System) of technical information needed when developing injection molds. Based on the results of injection-mold flow analyses and the use-case models of the people who develop injection-molds, the technical knowledge management system was designed and constructed in the engineering collaborative hub. This system consists of the integrated ontology model of technical information utilizing topic map approach and the retrieval system based on meanings in the field of injection mold development

국제환경의 변화와 한반도 통일 : 동북아 주변4강의 역학관계를 중심으로

이동윤 연세대학교 통일연구원 2000 통일연구 Vol.4 No.1

When the both extremity system, led by U.S.and Soviet, broke down and post cold war came, international society, getting out of military and securitary antagonistic relationship, entered into new competitions, which focused on economy, technology and information. It was thought that peace and security within the international society were naturally accomplished with post cold war, but the endless internal wars and external disputes are occurring and the mutual competitions to secure economic profits were deepening. Especially, when the consecutive economic crisis arises in East Asia, the World Powers are entering into severe competitions in having an important effect of themselves on East Asia.U.S., based on powerful economic strength, are spreading its economic profits and effects, and China and Japan are carring out the strategic foreign policy in order to show their leading role. In the past, as the division of the Korean peninsula was made by the 'Big Four', regardless of the Korean, the unification of the Korean peninsula couldn't be considered without the influence of the 'Big Four'. In order to move up the unification of Korea, weakening their effect on the unification of the Korean peninsula and showing the independent diplomatic ability, we must overcome the economic difficulties with which our country is confronted and draw up the independent unification plan through continuous communications and cooperations between North-South Korea.

선거제도의 변화와 민주화 이후 선거개혁 : 필리핀, 태국, 인도네시아의 사례 Cases of the Philippines, Thailand, and Indonesia

이동윤 서울대학교 국제지역원 2003 국제지역연구 Vol.12 No.1

본 연구의 목적은 동남아시아 국가들 중 민주화를 이룩한 필리핀, 태국, 인도네시아의 선거제도 변화과정과 민주화 이후 이들 국가들이 추진하여 온 선거개혁의 내용들을 살펴봄으로써 선거제도와 민주주의 사이의 관계를 고찰하는 것이다. 이를 위하여 본 연구는 민주주의의 기본 원리에 입각한 선거제도의 ‘경쟁성(competitiveness)'과 ’공정성(fairness)' 개념을 통하여 각 국가들의 선거제도 변화 과정을 검토하였으며, 민주화 이후 이들 국가들에서 진행되어 온 선거개혁의 내용들을 포괄적으로 비교하였다. 연구 결과 이들 세 국가들의 선거제도는 민주화 이전까지 경쟁성과 공정성의 차원에서 모두 미약한 수준을 표출하였으나, 민주화 이후 경쟁성을 회복하고 공정성의 수준을 향상시키는 방향으로 선거개혁이 추진되고 있다는 사실을 알 수 있었다. 또한 민주화 이후 이들 국가들의 선거개혁은 공통적으로 선거제도의 경쟁성과 공정성을 복원하고 증진시키는 방향으로 전개되고 있으나, 보다 세부적인 내용에서는 그들 국가들의 정치사적 경험에 입각하여 선거과정에서 나타나는 제반 문제점들을 해결하기 위한 제도적 처방을 달리 하고 있다는 사실을 알 수 있었다. The purpose of this paper is to review the changes of electoral system and the electoral reforms after democratization in the Philippines, Thailand, and Indonesia, and to compare similarities and differences of electoral reforms after democratization in each country. In particular, this study introduces the concept of 'competitiveness' and 'fairness' of electoral system. Based on these concepts, it also analyzes the changing process and the contexts if electoral reforms. This paper proposes that each country has experienced various changes of electoral system, and they similarly tried to elevate its competitiveness and the fairness by electoral reform after democratization. But the method of electoral reform is somewhat different in each country. The Philippines emphasized the competitiveness of electoral system by adopting the party list system and the guest candidate system. Thailand and Indonesia also improved the basic competitiveness of electoral system, and for the stability of party politics, limited the participation of non-partisan candidate in electoral process. Thailand made the distribution threshold of parliamentary seat in the party list system. Indonesia limited small parties, which received only small number of votes, to participate in next elections.

알루미나를 첨가한 Hydroxyapatite의 기계적 물성에 미치는 Ca/P 몰비의 영향

이동윤,이승규,박훈,김창은,Lee, D.Y.,Lee, S.K.,Park, H.,Kim, C.E. 한국세라믹학회 1991 한국세라믹학회지 Vol.28 No.5

The effect of Ca/P mole ratio (Ca/P=1.60, 1.67, 1.75) in the initial solution on the mechanical properties of alumina added hydroxyapatite was investigated. Hydroxyapatite was synthesized by precipitation method using Ca(NO3)2$.$4H2O and (NH4)2HPO4 as starting materials and 5 wt% of ${\alpha}$-Al2O3 was added to precipitation solution. The powder was calcined at 800$^{\circ}C$ and sintered at 1,150∼1,400$^{\circ}C$ under water vapor atmosphere. With the increasing of Ca/P mole ration in the initial solution, the amount of tricalcium phosphate formed from the decomposition of hydroxyapatite reduced and the sinterability and mechanical properties were increased. The bending strength and Vickers hardness of the specimen sintered at 1,300$^{\circ}C$ with the Ca/P mole ratio of 1.75 in the initial solution were 230 MPa and 650 kg/$\textrm{mm}^2$, respectively. The improvement of mechanical properties was attributed to not only the effect of Ca/P mole ratio but also the strengthening of sintered body by Al substitution for P ions.

公用收用과 行政상 損失補償

이동윤 大邱大學校出版部 1990 法政論叢 Vol.5 No.-

It is unavoidable that the imtervention of state in private life is gradually expanded by various reason in the contemporary state. And above all expropriation against private property is expanded. But despite of the public and social character of property, it is violation of the spirit of the guarantee of property that the loss of an individual caused by expropriation is left. That is to say. to guarantee the equal burden and realize the public welfare and regulate the public and private interest relevantly, it is adaquate to disperse and transfer the special sacrifice to the burden of the whole society by admitting the compensation against the special sacrifice in case that it is violation of justice or principle of equity to leave the accidental and special sacrifice of an individual encountered by public necessity. We can say that this is the very realization of social justice. The property is not guaranteed without just compensation. And it is difficult to expect the guarantee of the right of the freedom and the social right in the society which the property is not guaranteed. Because it will be gradually expanded to expropriate the property by public necessity, it is reguested to balance the public and private interest prudently for the realization of the principle of a social constitution state. To realize it. it is necessary to prepare the optimal countermeasure by the precedent and theory.
