Objectives : Obesity is a chronic metabolic disease caused by disorder of energy balance and lipid metabolism. This study was conducted by histopathology and histomorphometry to investigate the anti-obesity effects of mixed water extract of Plantaginis Semen & Poria (CJB) on liver, epididymal fat pads and pancreas zymogen granules in obese rats induced with high fat diet, Method : Male Sprague-Dawley rats to be divided four groups were fed into four different treatments: normal (NOR) diet, high-fat (HF) diet, HF diet+CJB (100 mg/kg and 300 mg/kg, P.O.) for 8 weeks. The weekly body weights were measured in four experimental groups, respectively. Also histopathological and histomorphometrical changes of liver, epididymal fat pads and pancreas zymogen granules were observed in normal control and obese rats, respectively, Results : Adminstration of CJB significantly reduced body weights compared to those of HF group for experimental period. After 8 weeks, liver weights in the CJB groups were lower than those of HF group. In addition, HF diet related steatohepatitis, adipocyte hypertrophy, exocrine disturbances (decreases of pancreatic zymogen granules) were also dose-dependently inhibited by treatment of test material, CJB 100 and CJB 300 as compared with HF group, respectively, Conclusion : Based on the results, it is considered that CJB will be showed hepatoprotective and anti-obese effects, may be directly and/or indirectly mediated by pancreatic zymogen granules because they dose-dependently inhibited steatohepatitis, hypertrophy of adipocytes and decreases of pancreatic zymogen granules induced by HF diet supply, respectively.

불연속 지형을 지나는 천수 흐름을 해석할 수 있는 Hwang의 기법이 채택된 수치 모의를 댐 붕괴 흐름에 의한 직립 홍수터의 범람 실험과 비교하였다. 모의 결과는 저수지, 저수로, 홍수터로 이루어진 실험 수로에서 측정한 결과와 잘 일치하였다. 특히, 댐 붕괴 흐름이 직립 홍수터로 차고 빠지는 과정이 잘 모의되었다. 흐름 저항의 종류에 따른 모의 결과의 차이는 미미하였다. 이 연구를 바탕으로 도심 하천의 범람 예측에서 정확도를 높일 수 있을 것으로 기대된다. Numerical simulation with Hwang’s scheme, which can analyze shallow-water flow over discontinuous topography, was compared with a laboratory experiment of flooding on a perpendicular floodplain with dam-break flows. The simulation results were in good agreement with the results measured in an experimental flume with a reservoir, channel, and floodplain. The wetting and drying process on a perpendicular floodplain with a dam-break flow was particularly well simulated. The difference in simulation results according to the type of flow resistance was insignificant. The results of this study are expected to improve the accuracy of predicting inundation in urban rivers.

발전국가이론은 국가가 경제에 적극적으로 개입하여 경제성장에 성공할 수 있음을 일본을 비롯한 동아시아 국가 사례를 들어 보여주었다. 한국의 경제 발전 경험도 발전국가이론의 유용성을 보여주고 있다. 하지만, 경제성장을 설명하기 위해 필요한 변수를 경제성장 초기 전후에만 한정 짓는 것은 발전국가론의 한계이다. 한국의 경우 경제성장이 시작되기 전 이미 수백 년 이상 정교한 중앙집권적 국가를 경영했던 경험이 있으며, 상당한 수준의 교육, 일본 식민지하에서의 산업화 경험 등 발전에 필요한 조건의 상당 부분을 갖고 있었다. 당시 국제 정치경제적 요건도 발전국가가 작동하기에 유리한 조건을 형성하고 있었다. 한국 발전국가는 이처럼 선행했던 역사적 조건을 활용할 수 있었기 때문에 작동 가능했던 것이다. 이글은 한국 경제 발전 관련 변수를 시기적으로 확장하고 경로의존이론을 활용하여 발전국가이론을 보완, 확장하였다. 이를 통해 한국의 경제성장은 다양한 역사적 배경 요인에 힘입었으며, 사회구성원들의 행동 결과가 한국 발전국가 작동에 중요한 영향을 미쳤다는 점을 보여주고자 하였다. While the developmental state theory is known to successfully explain the East-Asian economic development, it has often been criticized for lacking a historical perspective. This paper attempts to overcome this shortcoming by examining the historical factors that preceded the development, which have influenced the working of Korean developmental state. Incorporating these historical factors, this paper takes a path-dependent approach to broaden the scope of the developmental state theory, so as to deepen our understanding of it.
제국주의자 사탄 : 신세계와 제국주의에 관한 밀턴의 견해

The image of the new world is presumed to be important in Milton’s poetry. In Milton’s Paradise Lost, the new world is important and the imperialistic threat of Satan to the new world is also one of the major interests in this epic. Satan launches into the chaos to find the new world with some curiosity for the new world and its dwellers. Satan, however, betrays his distorted view on the new world and its people, which we can find in the European new world explorers. Satan’s journey to the new world also looks like the explorer of the new world and merchants from the colonized land. Eden is described with realistic geographical details. With its firm root in geography Eden seems to be more real than just an imaginary paradise. Satan is looking at the garden of Eden with the eye of an imperialist. And we are introduced to Eden by and with Satan. Satan also sees beyond the outward meaning of Eden, which the residents seem to overlook. But his imperialistic insight deteriorates the meaning of Eden. Milton employs the image of the middle age maps which placed the world in the middle and with the outer world full of monsters and horrible things. Satan journeys from the monstrous world to the new, paradisiacal land. Satan is conscious of his journey to the new land. It means that he has the identity of the old world. Here, not only imperialism, in which Satan seems to believe, but also the old world, which supports the causes for the imperialism is heavily criticized. The new world in this epic which the imperialists want to colonize is in the religious and political level.
