정무일,탁인자,이근무,Moo Ill Chung,In Ja Tak,Kun Moo Lee 대한화학회 1975 대한화학회지 Vol.19 No.6

Dodecyl pyridinium chloride(DPC)와 tetradecyl pyridinium chloride(TPC) 水溶液의 0~70mM 濃度領域에서의 光散亂硏究로 각각 약 17mM과 3.5mM에 있는 第一 cmc外에 제이 cmc가 각각 약 43mM과 8mM에 있음을 알 수 있다. 第二 cmc는 添加物 KCl에 依하여 크게 영향을 받고 이로 因하여 第二 cmc는 低下된다. 第一 cmc에서의 DPC와 TPC 水溶液의 미셀分子量은 각각 20,800과 15,600이었고 그들 미셀의 이온化度는 각각 0.092와 0.226이었다. The light scattering studies of the aqueous solution of dodecyl pyridinium chloride (DPC) and tetradecyl pyridinium chloride (TPC) over the concentration range of 0~70 mM revealed that there exists a so-called 2nd critical micelle concentration (cmc) at about 43 mM and 8 mM respectively in addition to their 1st cmc at 17 mM and 3.5 mM. The 2nd cmc was greatly influenced by additives KCl, which lowered the 2nd cmc. The micelle molecular weight of DPC and TPC solutions at 1st cmc were 20800 and 15600 and the degree of ionization of their micelles at 1st cmc were 0.092 and 0.226 respectively.

정무일,이창석,Jeong, Moo-Il,Lee, Chang-Suk 한국전자파학회 2007 한국전자파학회논문지 Vol.18 No.1

LDR(Low Date Rate) UWB(Ultra Wide Band) 시스템에서 chaotic 신호를 이용한 OOK(On Off Keying) 통신 방법이 선택적 사항으로 채택되어 있다. 이 시스템에서 중요 회로 중에 하나인 chaotic 신호 발생 회로는 현재 대부분 아날로그 형태의 피드백 구조를 이용하고 있으나, 아날로그 형태의 피드백 구조는 공정 변화에 대한 취약점이 있어 양산성에 어려움이 있다. 이를 해결하기 위해 본 논문에서는 0.18 um CMOS 공정을 이용하여 디지털 구조의 PN-sequence를 응용하여 중심 주파수 4 GH에서 2 GHz의 대역폭을 갖는 Quasi-chaotic 신호 발생 회로를 설계 및 검증하였다. Chaotic OOK(On-Off Keying) modulation method can be used in LDR(Low Data Rate) UWB systems. The chaotic generator in one of the most important circuit in this system. The traditional chaotic generator circuits using analog feed back technique have low yield characteristic due to the process variation. A novel quasi-chaotic signal generator using digital PN-sequence in proposed in this paper and verified in 0.18um CMOS teleology.

정무용,Chung, Moo-Yong 한국기술사회 2006 技術士 Vol.39 No.6

The important role of canal is moving goods and the canals from all over the world has contributed much to method of transporting goods. But, the canal system accounts rfor 25% of the total moving goods. One of its main goals is to reduce overland transportation costs were 30% more expensive than moving goods over water. We plan to build a Korea inland canal system and need to from a scheme of building a multi canal. We should consider positive aspect of this plan, on the other hand a study of the conal's environmental impact is required prior to beginning any construction. Finally, offer our opinion on the vision of Korea inland canal that aspect5 of national land development.

학습자의 특성과 이러닝 시스템이 강의만족에 미치는 영향에 관한 연구 : 강의몰입의 매개효과를 중심으로

정무관,최항석,이해영,김민지 한국상업교육학회 2014 상업교육연구 Vol.28 No.3

본 연구는 이러닝의 학습효과를 향상시키기 위한 방안을 모색한 것으로, 기존의 연구들의 문제점 을 해결하고자 하였다. 즉, 기존 연구들은 특정 요인만을 독립변수로 고려하여 이러닝 학습효과에 대한 종합적인 시각을 제공하지 못하였다는 점과 특정 요인이 어떠한 과정을 거쳐 이러닝 학습효과 에 영향을 미치는지를 고려하지 못하였다는 문제가 있었다. 이를 고려하여 본 연구에서는 학습자의 셀프리더십, 학습자 특성, 그리고 이러닝 시스템 환경 및 컨텐츠를 통합적으로 고려하여 매개변수인 강의몰입에 어떠한 영향을 미치는 지 분석하고, 종속변수인 강의만족과에 미치는 영향을 알아보았 다. 국내 서울소재 여자대학교의 학생 200명을 대상으로 설문을 통한 실증 분석을 실시한 결과, 학습 자의 특성 중 학습능력, 자기유능감과 이러닝 시스템의 컨텐츠가 매개변수인 강의몰입에 긍정적인 영향을 미치는 것으로 나타났다. 또, 강의만족에 있어서는 학습자의 특성 중 학습능력과 이러닝 시 스템의 컨텐츠가 긍정적인 영향을 미치는 것으로 나타났다. 하지만, 학습효과에 영향을 미칠 중요 요인으로 고려한 학습자의 셀프리더십은 강의몰입과 강의만족에 유의한 관계를 나타내지 못하였다. The purpose of this study is to examine what components related to e-learning affect learning effects, synthetically. We focus on the effect of learner's characteristics and e-learning system in the e-learning effectiveness. We collected the subjects who were 200 female undergraduate students and had taken an e-learning course. The results of an analysis show the following: First, learning ability, self-efficacy considered as learner's characteristics, and e-learning system contents considered as e-learning system affect lecture commitment of learners. And then, learning ability and e-learning system contents affect lecture satisfaction of learners. In cases of mediating effects of lecture commitment, learner's characteristics have effect on lecture satisfaction through lecture commitment. However, this study does not show the relationship between self-leadership and lecture commitment and satisfaction. The implications and limitations of this study were discussed.

한국전쟁과 서구미술

정무정(Chung Moojeong) 서양미술사학회 2000 서양미술사학회논문집 Vol.14 No.-

Ever since its outbreak. the Korean War has been the object of scholarly attention to reveal its military, political, diplomatic, and cultural aspects. A recently published book 1he Korean War: Handbook of the Literature and Research (1996) introduces major works on several topics associated with the Korean War. Unfortunately, however, the response of the art world to the war seems to have rarely been discussed. In this paper, I will examine the MOMA’s 1951 exhibition Korea: The Impact of War in Photographs, Pablo Picasso’s Massacre in Korea of 1951 and War of 1952, and David Smith’s Parallel 42 of 1953. Interestingly, these works, all done during the war, reveal polarized attitudes toward it and have a lot to do with the war situation at the moment. On February 13, 1951, when American forces were struggling to recapture the city of Seoul in Korea, the MOMA opened a photography exhibition entitled Korea: The Impact of War in Photographs with photographs from newspapers and popular magazines which were reporting on the very war on a daily basis. An examination of photographs included in it reveals that the exhibition was filled with scenes of soldiers and civilians dying and wounded, withdrawing and fleeing. In particular, it focuses on the critical moment of the Korean War when MacArthur’s ‘home-by-Christmas’ attack was frustrated, when American forces were forced to withdraw hurriedly to the south. Given that public opinion on the Korean War was getting worse at the moment, the MOMA’s focus on the image of losing American forces can be seen as a way to reveal the sufferings caused by the Chinese Communists, thereby condemning their intervention in Korea and enhancing the public support for the war. It is quite consistent with the past activities of the MOMA that tried to serve as a cultural weapon for national defense and engaged in a number of wartime cultural programs. Inspired by reports of American atrocities during the Korean War, Pablo Picasso as a declared Communist produced Massacre in Korea which showed a group of naked women and children facing execution by heavily armed soldiers. However, the Communists dismissed the work as ‘politically incorrect’ because they could not ascertain whether the victims were North or South Koreans, and the soldiers were Americans or Chinese. In the middle of 1952, Picasso again took up the Korean War as his subject for War, thereby making another bid for winning the recognition and approval of the French Communist Party. This time, he carefully brought to the fore two crucial events of the war, which the Communists could exploit as propaganda materials: MacArthur’s “home-by-Christmas” offensive and germ warfare. And the Communists were so satisfied that they hailed it as ‘symbol-studded mural.’ David Smith produced Parallel 42 on 26 February 1953, when the peace talks at Panmunjom, Korea, were at a standstill. Executed in steel, the sculpture shows a small silhouette of the Korean peninsula at top surrounded by a couple of ominously protruding shapes. Considering that the 38th parallel was almost the symbol of the Korean War, Smith’s sudden attention to the 42nd parallel means that he studied the war and sought to address it in his own terms. In this context, it is significant that the 42nd parallel refers to the latitude of the source of the Yalu River. During the Korean War, the Yalu River was frequently associated with aggressiveness of American forces. Thus Smith’s Parallel 42 can be interpreted as an indictment of American forces. The Korean War was a touchstone by which believers in the two world systems could demonstrate their loyalty and affirm their support of the side they had chosen, or had felt compelled to choose. The art world was no exception to this. Under the intense ideological passions of the Cold War, artists sought to win the sympathy of mankind or to condemn their ideological enemies. Alth
