研究室紹介
Professor Jeong-Won Park's research spans international law and mechanical engineering, with a focus on the intersection of legal principles and technical systems. His legal research examines self-determination, minority protection, and the normative foundations of political participation, particularly in post-Cold War and WTO dispute settlement contexts. In engineering, his work centers on structural dynamics, vibration analysis, and non-destructive testing using wave propagation and dynamic characteristics in railway and plate structures. His interdisciplinary approach integrates legal theory with applied mechanics, especially in assessing structural integrity through vibro-acoustic and dynamic response methods.

8It is generally accepted that self-determination will be effectuated through the formation of an independent statehod in its external aspect. However, as son as a self-determining regime attains independent statehood, internal self-determination primarily operates as a governing and organising principle of the State. A people within a State, as holders of the right to self-determination under international law should have the right to choose their form of government, and their economic, social,
If the feature of the debate on the right to political participation in international law during the Cold War era was ideological rather than substantive in its nature, it appears now to be moving in the direction of seeking substantive normative aspects for political participation. It is true that even today as the ideological conflicts between capitalism and communism have ended, the essence of the principle of democracy may be debatable depending on value judgments and unique political tradit
굽힘파 전파 특성을 이용하여 지지강성을 도출하고 이를 이용한 레일체결장치의 결함 검출 시험법을 제안하였다. 점탄성 패드로 지지되고 체결장치로 고정된 레일의 진동 응답은 주파수에 따라 지지단 동특성에 크게 영향을 받는다. 체결장치에 결함이 발생할 경우에는 구조적인 불연속성으로 인해 굽힘 파동의 전파 특성이 변화하게 된다. 이러한 변화를 감지하기 위해서 전달함수법을 이용해 주파수에 따라 변화하는 레일 지지단 동특성을 측정하였다. 연속 스프링으로 지지된 레일 응답으로부터 예측한 레일의 보존에너지를 이용해 결함에 대한 파동 전파의 민감도를 해석하였다. 민감도 해석 결과와 동적지지강성 변화를 측정하여 손상지수를 계산하고 결함 위치를 추정하였다.
The Panel report of the EC-Biotech Case, GMO dispute before the WTO, contains many noteworthy findings. The most extraordinary and potentially far-reaching are those regarding the scope of the SPS Agreement. The Panel report of the case has vividly illustrated that its interpretation of international treaties can be problematic in the process of judicial review in the WTO dispute settlement mechanism. What is critically important point is that the Panel has ignored the external sources of public

복합 구조물의 충격 진동 특성을 이용한 취약성 분석 기법을 제안하였다. 프레임 요소로 구성된 구조물의 충격 거동을 파악하기 위해서 스펙트럴요소법을 적용하였다. 티모센코 보함수를 이용해 고속 충돌에 의한 고주파 성분을 포함하는 충격파 전파 특성을 시뮬레이션하였다. 구조물의 결합부분에서는 종방향과 횡방향 파동의 상호 작용을 고려한 파동 전달을 해석하였다. 충격력이 구조물에 작용할 경우 주파수 및 시간 응답을 얻고 전체 구조물에서 충격에너지 전파 특성을 파악하였다. 구조물의 위치별로 계산된 최대가속도 크기와 시스템을 구성하는 주요 부품의 허용 가속도 기준에 의한 취약확률 함수를 정의하고 시스템의 취약 확률을 계산하였다. 제안된 취약성 분석 절차를 이용해 3 차원 전투 차량의 충격 응답을 얻고 충격에 취약한 구조물 위치를 파악하였다.
The dynamic mechanical properties of different high-strength steels were measured and comparedbased on their respective microstructures. Beam-shaped test specimens were excited using anelectric shaker while vibration responses were measured using a non-contact laser sensor. Flexuralwave propagation was analyzed to precisely determine material damping. Measured propertieswere compared to those of carbon steels. In addition, the effects of grain size determined by opticalmicrographs on the dynamic
The purpose of this study was to analyze the vibro-acoustic characteristics of a stiffened rectangular plate at high frequencies. The stiffeners attached along the plate surface were assumed to have rotational and translational stiffness and inertia. The harmonic response of the stiffened plate were predicted and compared using the Rayleigh-Ritz method with two different trial functions – polynomial and beam functions. The variation of the spatially averaged mean square velocity and the modal ch
