항만분야 공적개발원조(ODA)의 딜레마 해소를 위한 제도 개선방안
국제화 시대에 발맞추어 세계 각국은 국가 간 빈익빈 부익부 현상을 해결하고 개발도상국의 경제발전 및 복지수준 향상을 위해, 공적개발원조(ODA; Official Development Assistance)를 통한 그들 간의 협력에 힘쓰고 있다. 과거 수원국에서 공여국의 입장으로 위상이 변화된 우리나라 역시 아직 초기단계에 머물러 있지만, OECD의 회원국으로서 ODA 사업에 적극 동참하고 있다. 특히 최근 들어 우리나라에서는 항만과 관련된 분야에서 ODA의 중요성이 부각되고 있다. 따라서 본 연구는 신제도주의와 사마리아인의 딜레마 게임의 관점에서, 우리나라 항만분야 ODA의 현황 및 관련 제도를 분석하여 사마리아인의 딜레마 상황을 발생시킬 수 있는 구조를 찾아내고, 이러한 딜레마를 해소하기 위한 제도적 방안을 모색하는 것을 연구목적으로 하였다. 분석을 통해서 항만분야 ODA 제도와 관련된 딜레마 구조를 확인하였다. 그리고 분석결과는 현장 중심 원조체제의 강화, 수원국의 협력을 유도하는 보상체제 확립, 신뢰할 수 있는 협박의 제도화 등과 같은 제도개선방안들을 제안하였다. 이와 같은 연구의 분석결과는 ODA 연구의 이론적 모형을 개발하고 항만분야 ODA의 효과성을 제고시키는데 기여할 수 있을 것이다. 【In accordance with the global age, countries in the world try to dedicate to collaboration among them through ODA (Official Development Assistance), in order to solve the-rich-get-richer and the poor-get-poorer problems among countries, to develop the developing countries' economies, and to improve their level of social welfare. Also, Korea is so active in ODA as a member of OECD, even if it is in the initial process. Nowadays, in Korea, the importance of ODA in the field of port has been brought into relief. Accordingly, the paper intends to analyze the dilemma structure of port ODA from the perspectives both of new institutionalism and Samaritan's dilemma game, and it tries to seek the improvements of ODA institutions to create effective outcomes based on the analysis. Through the analysis, dilemma structure was identified regarding the institutions of port ODA. And the results of the analysis suggested the improvements of port ODA institutions including strengthening of on-the-spot aid system, establishment of payoffs system for inducing recipient countries' efforts, and institutionalization of reliable threat. It would contribute to develop the theoretical model of ODA analysis and create effective outcomes of ODA in the field of ports.】
Critical resistance for multi-phase composite materials
The effect of interfacial resistance on the effective conductivity of a multi-phase composite material was studied. The composite under study is composed of a matrix surrounding different types of circular cylinders arranged in rectangular order. It was assumed that the interfacial resistance is concentrated on the surface of the cylinders. For any direction of calculating the effective conductivity of the system, a condition was found in which the effect of cylinders of one type can be neglected. This condition may be estimated by R k − 1, where R and k are the non-dimensional interfacial resistance and the relative conductivity of the neglected cylinders, respectively. The case R = k − 1 applies when the same relation exists between the interfacial resistance and conductivity of all types of cylinders.  2003 Elsevier Science B.V. All rights reserved.
Computer Simulation Modeling
Computer simulation as a research methodology is presented as the intersection of modeling, simulation, and computer analysis. Five component parts of simulation models are identified: input variables, output variables, assumptions, algorithms, and parameters. Computer simulation (CSM) has two primary uses for those interested in the study of organizations or who work within them: theory development and policy planning. The advantages and disadvantages of CSM for each of these purposes are examined and recent examples for each are explored.
