經濟發展과 農業生産力의 問題

鄭雲溶 空軍士官學校 1966 論文集 Vol.1 No.-

This thesis aims to analyse the interrelation of the economic development and agricultural productivity in Korea. Today, underdeveloped countries in cluding Korea, which gained political freedom from colonial and absolute govern, endeavour to gain economic freedom from poverty. The freedom from poverty in undeveloped countries will be achieved by establishing of self-sustained economy and the self-sustained economy will be supported by organizing of Neo-Nationalism. We can devide various theories of underdeveloped countries into three parts. First, The Pure Economic Approach which developed by post-keynsian. Second, The Socio-Economic Approach which is theorized by J. H. Boeke and S. H. Frankel. Third, The Politico-Economic Approach or International Relations Approach which is theorized by H. Myint, E. Staley, M. Dobb. I think that when the combination of the politico-economic approach and Noe-Natienalism result in the mixed economic system, It is possible to establish self-sustained economy. From this view of point, I try to review the method of economic organization of Neo-Nationalism through analyzing the agricultural problems and the disguised unemployment in Korea. The contents are as following: Chap. I. Introduction Chap. II . The Development of Underdeveloped Countries Chap. III. The Industry Structure and Economic Development in Korea

순차적 수치해석기법을 이용한 교량 거더의 플러터 발생풍속 예측

정운용,권순덕 한국풍공학회 2002 한국풍공학회지 Vol.6 No.2

A sequential numerical procedure for predicting the flutter onset velocity of bridge girders without wind tunnel tests is presented. The proposed procedure consists of two phases. In the first phase, the unsteady aerodynamic forces acting on moving rigid bodies are evaluated from the finite element analyses. In the second phase, the flutter onset velocities are estimated by solving the aeroelastic equations. The results of numerical simulation for the two generic bridge deck sections show fairly good agreement with those of experiments. 교량 데크의 플러터 발생풍속을 예측할 수 있는 순차적 수치해석 방법을 제안한다. 제안된 방법은 두개의 단계로 이루어져 있다. 첫번째 단계에서는, 진동하는 강체에 작용하는 비정상 공기력을 산정하고, 두번째 단계에서는, 공탄성방정식을 풂으로써 플러터 발생풍속을 산정하는 것이다. 두개의 교량 데크에 대한 수치해석 결과는 실험과 비교적 잘 일치하는 결과를 보인다.

STEP AP214 에 근거한 자동차 PDM 의 구현 방안

정운용,한순홍 한국자동차공학회 1996 한국자동차공학회 춘 추계 학술대회 논문집 Vol.1996 No.11_2

The exchange of product data becomes a key issue in globalized enterprise environment. But there is no clear solution to share heterogeneous information reside in diverse information resources. To share automotive product information among diverse organizations, a reliable neutral information standare and communication the standard for exchanging automitive product model through its whole life cycle. This paper suggests an automotive PDM implemented on the intemet based on STEP AP214 physical files containing differnt kinds of data can be shared on the internet using JAVA applet.

南雲 李弘稙의 韓國古代史 認識

Hong-jik Lee made his studies into two books Studies on the Ancient Culture of Korea and Studies on the Ancient Korean History. I aimed to investigate his understanding in the ancient Korean history by studying the latter book. Several outcome has been gained through the study. Firstly, started study of the ancient history with a paper using Nihon-Shogi, he is a thorough scholar who insist that the use of document sources is the basic of studying history. Secondly, he empathizes that perfect positive criticism on historical records should be a prerequisite for records-based study of ancient Korean history. Thirdly, he usually compares Korean cases to Chinese or Japanese cases as choosing comparative case study. Forthly, he understands the importance of linking ancient history to mythology, anthropology, archeology, art history, the science of religion and so on. Fifthly, he intends to clear up the interrelationship between the different parts of the ancient Korean history by studying those parts synthetically. Sixthly, he believes study of history must contribute to the development of human society and eventually enlighten the public. To Hong-jik Lee, after all, studying history is a trial to overcome the limitation of records and to depict a extended historical view by adapting results of fields of various studies. His passive attitude toward the early ancient history, however, due to the restraint of the times, makes one feel the miss.

Background : A mummy is a dead body of a human being or an animal that has been preserved artificially or naturally from decaying. Because the natural environment of Korea isn't appropriate for mummification and Korean people haven't artificially made mummies, mummies were rarely studied in Korea. Methods : On September 6, 2002, a well-preserved female mummy was found in the grave of a family in Kyunggi-do. She was submitted to a thorough autopsy examination along with the review of genealogical documents. Results : The mummy died in winter. She was pregnant and the fetal head was observed at the vaginal orifice. The uterine wall was ruptured, and the peritoneum was discolored, probably by hemorrhage. Histologically, the gastric mucosa was well preserved. On the smear cytology of gastrointestinal material and the fluid from the coffin, pollens and parasitic eggs were observed. The woman seemed to be death from hypovolemic shock due to uterine rupture during the 2nd phase of labor. Conclusions : From this case, we concluded the causes of the woman's mummification included the cold and dry circumstance at the time of her death, and the thick mortared wall of the grave that completely isolated the body from the outside.

『三國史記』交聘 紀事를 통해 본 羅濟同盟時期의 再檢討

정운용 충남대학교 백제연구소 2006 百濟硏究 Vol.44 No.-

The most approved periods of Silla­Baekje Alliance has been from A.D. 433 to 554. Such approval, however, was made before the discovery of Jungweon Koguryo Monument, which contents how matters stood in 449. As so, this article is to review the compromise and rupture of Silla­Backje Alliance. Having reviewed texts related to the exchange of envoys in Baekje­bonki, {Samguk Sagi(History of the Three Kingdoms)}, the exchanges of envoys in 433 and 434, which the academic world has focused on, were also found during 1stC∼4thC. This proves that the periods of Silla­Baekje Alliance existing in records should be understood by their efforts to keep the alliance and their performing concerted operations when it is needed. In conclusion, the compromise of Silla­Baekje Alliance is assumed to be made in early 455 based on the fact that Silla aided Baekje defeating Koguryo, although the war is supposed to be a limited warfare. In addition, the rupture is understood to be made in 554 when Baekje failed the attack to the Kwansan Fortress, as the academic world has understood. 기왕에 학계에서 이해하여 온 羅濟同盟의 시기는 433∼554년이었다. 그러나 이러한 이해는 449년의 상황을 전하고 있는 中原高句麗碑의 발견 이전에 형성되었던 것이다. 따라서 이 글은 나제동맹의 성립 및 결렬 시기를 재검토해 보고자 하였다. 이 글은 『三國史記』 百濟本紀의 交聘 관련 기사 내용에 대한 검토를 통해, 기왕에 학계에서 주목하여 온 433ㆍ434년의 百濟와 新羅 사이 交聘과 같은 내용은 1∼4세기에서도 찾아짐을 확인할 수 있었다. 따라서 사료 상 實在하는 나제동맹의 시기는, 관련 당사국 사이에 그의 유지를 위한 노력과 유사시 상호 공동 작전을 수행하는 것을 통해 파악해야 할 것임에 有意하였다.그 결과, 비록 소규모의 局地戰이라 판단되나, 455년 10월 백제를 도와 고구려를 물리치는 신라의 군사행동과 그 해 9월 백제의 왕위 계승을 주목하여, 나제동맹의 성립은 455년 上半期로 추정하였다. 아울러 나제동맹의 결렬은 기왕의 통설적 이해대로 554년 管山城 전투에서 백제가 패배함으로써 초래된 것으로 파악하였다.
