오진석(Jin-Seok Oh),장재희(Jae-Hee Jang) 한국항해항만학회 2018 한국항해항만학회지 Vol.42 No.3

해상에서 운용되는 일점계류형 해양플랜트의 태양광 발전 시스템은 독립 전원 체계를 가지고 있으며, 해상 환경, 부조일수 등의 영향으로 안정적인 전력을 공급하는 것이 중요하다. 이러한 이유로 태양광 패널을 여러 방향으로 설치하게 되는데, 이 때 각 패널마다 입사되는 광량이 달라지므로 부분음영현상이 발생하게 된다. 육상용 태양광 발전시스템의 발전량은 위도의 영향을 받으므로 우리나라의 경우 30~36° 사이의 각도로 설치하는 것이 일반적이나, 일점계류형 해양플랜트에 설치되는 태양광 발전 시스템의 경우 부분 음영 현상에 의해 최대전력점이 제어 가능 범위 밖에 존재하는 경우가 발생하게 되고 이는 전력 발전 손실이 된다. 이 때 두 패널의 광량차이를 줄임으로써, 최대 전력점을 MPPT 알고리즘이 추종 가능한 범위에 존재하게 하여 발전 효율을 더 높일 수 있으며, 시뮬레이션 결과 설치각도 20°에서 가장 높은 발전 효율 가짐을 확인하였다. A solar power generation system on single point moored offshore plant has independent power system In order to satisfy the maritime environment and account for the number of sunless days, it is important to supply stable electric power to the systems. For these reasons, solar panels are installed in multiple directions. However, a partial shading effect occurs because the amount of light incident on each panel is different. The generated power by the solar generation system installed on land is affected by the latitude, then it is installed at an angle of 30 to 45°. in the case of Korea. In the case of a solar power generation system installed in a mooring type of marine plant, there is a possibility that the maximum power point is outside of the controllable range due to the partial shading effect. Therefore, a power generation loss occurs. By reducing the light amount difference between both panels, the maximum power point can exist in a range where the MPPT algorithm can track the power. The purpose is so the power generation efficiency can be further increased. In this paper, simulation results show that the highest power generation efficiency is obtained at an installation angle of 20°.

해방 전후 최호진(崔虎鎭)의 학문세계와 학술활동

오진석 ( Jin Seok Oh ) 연세대학교 경제연구소 2014 延世經濟硏究 Vol.21 No.2

본고는 권력과 금전의 유혹에 초연한 자세를 유지한 채 오로지 강단과 연구실을 지키며 후학 양성과 연구에 매진해 한국 경제학의 발달과정에서 큰업적을 남긴 崔虎鎭을 대상으로 그의 학문세계의 형성과 전개과정을 검토한 논문이다. 그는 집안의 내력과 관련하여 일찍부터 투철한 배일의식을 가지고 있었는데, 보성전문 법과에서 수학하면서 김광진과 백남운의 아시아적 생산양식론을 둘러싼 논쟁을 지켜보며 경제사연구에 뜻을 굳히고 나름의 연구방향을 모색하였다. 이후 구주제대에 유학하면서 전공을 경제학으로 바꾸고 당대 세계학계의 유력한 경제이론들을 비교적 균형 잡힌 시각에서 체계적으로 배웠다. 특히 자본론과 국부론 모두를 정독시키며 좌우에 치우치지 않은 균형 잡힌 경제학 연구를 강조했던 지도교수 波多野鼎에게 큰영향을 받았다. 유학시절 형성된 열성적인 학업태도의 결과 그는 1942년에 『근대조선경제사』를 발간하기에 이르렀다. 해방 이후 그는 백남운의 영향 아래 학문과 지식을 활용해 신국가건설에 기여해야 한다고 생각해 조선학술원, 민족문화연구소 등에서 활약하고 신설된 경성대학 경제학과의 교수가 되어 이 학과를 한국 최고의 경제학 고등교육기관으로 만들기 위해 많은 노력을 기울였다. 한국어로 된 경제학 교과서 저술에 힘을 기울였고, 한국경제사연구에도 매진하여 『근대조선경제사연구 제1권』을 저술하였다. 그는 이 책에서 아시아적 생산양식론을 전면적으로 도입하여 한국사회의 ‘아시아적 정체성’을 해명하는 데에 연구의 목표를 두었다. 그러나 그의 ‘정체성론’은 ‘아시아적’이라는 특수성을 전제로 하기 때문에 특수성의 농도에 따라서는 보편적인 세계사적 발전법칙의 관철을 부정하는 이론으로 연결될 우려가 있었다. 이 때문에 1960년대에 들어서 신진 학자들에 의해 이른바 ‘내재적 발전론’에 입각한 연구들이 등장하면서 그의 연구는 극복대상으로 설정되었다. This paper examines the academic world and career of Choi Ho-chin, who had a profound effect on the development of both the field and the later scholars of Korean economics. Choi Ho-chin was well-known for keeping his research and lectures against the influence of both political power and money. Due to his family background, Choi had anti-Japanese sentiments from a young age and observed the debate between Kim Gwang-jin and Paik Nam-woon on the Asiatic mode of production while studying at Bosung College. He decided to study economic history and find his own research path. While studying at Kyushu Imperial University, he switched his major to economics and pursued a systematic, but comparatively balanced, study of the main economic theories of the day. Choi Ho-chin was particularly influenced by his academic adviser, Hatano Kanae, who required him to closely read The Wealth of Nations and Das Kapital, while maintaining a balanced perspective in his economic research. The results of his experience studying abroad were apparent in his work published in 1942, Modern Joseon Economic History. After Liberation in 1945, Choi was influenced by Paik Nam-woon to use his studies and knowledge in contributing to the establishment of the new nation. Choi Ho-chin participated in the Joseon Academy and the National Culture Research Institute, as well as becoming a professor in the department of economics at Gyeongseong University. He published various economics textbooks in Korean and continued with his research into Korean economic history, publishing volume one of his Studies of Modern Joseon Economic History. In this book, he used the Asiatic mode of production to explain the “Asian stagnation” of Korean society. However, his “stagnation theory” was based on a particularly Asian characteristic, which could be used to challenge the conventional perspective on the principles of global development. Consequently, his research influenced scholars in the 1960’s who advanced “internal development theory” in order to overcome his research.

Abrupt landslide might cause the loss of properties, casualties, and the block of traffic on the road especially during rainy season in Korea. In this paper, a method using Ground Penetrating Radar (GPR) is proposed for the purpose of sending an early warning prior to a possible landslide. The GPR system measures the change of moisture content in the soil until it reaches a threshold of initiating the failure. A metal target is used as a reflector while the soil sample is moisturized at different levels of moisture content. Then, the dielectric constant of the soil is obtained based on the time of returned signal from the reflector. The results showed that this method is possible in predicting the change of moisture content within the soil sample and for the application to the landslide warning system.

미술 비평가로서의 앙드레 브르통과 현대미술

오진경(Jin-Kyeong Oh) 서양미술사학회 1996 서양미술사학회논문집 Vol.8 No.-

Andre Breton was deeply aware of the problems of absurdity and contradiction in the real world after the First World War and participated in the Dada movement intending to revolt against the hypocrisy and the conventions. Dada emphasized on: ‘deny everything, destroy altogether and, not to believe all the instructions, even Dada’s lessons’. Therefore it was expected that the dadaist could not help giving up Dadaism itself from the beginning. Then Breton presented a more hopeful and concrete proposal to rescue the world than Dada. His new plan was to create a surrealistic world which can settle all the inconsistencies and absurdities of the real world and set free the human being from the traditions and taboos. It was to perform a total liberating movement conceming the intellectual, social, and artistic field. Breton’s writings on arts were based on his view of world, and his belief that one can reach the surreal world by means of poems or plastic arts. This conviction was never given up to the end of his life, and had a great influence on the history of modem art. Breton proposed “the communicating vessels” as a means to solve problems caused by conflicts of contradictions. This idea indicates the passage through which makes the contradictory elements in the real communicate freely each other. That is the surreal world in which it is possible to communicate without any problem. While Breton conveyed a spiritual and moral message to move forward to the ideal world in his critical writings on plastic arts, he did not suggest certain concrete styles. So artists who wanted to follow Breton’s message could search for or invent the methods to reach the desirable world for themselves. Breton’s message was not a specific form or method but a kind of goal and attitude. Therefore his selection of the art works for criticizing covered the various period and styles which range from past to present, no matter what it is figurative or abstract, subjective expressions or presentation of real objects. Breton surveyed artists and their work with a conviction that the art must realize the requirement of the times and society like other cultural activities. The reason why Breton rarely mentioned on the stylistic or plastic aspects in his critical writings is that he was particularly interested in subjects of works such as the views and attitudes of artists toward the world. From the beginning to the end of surrealist movement, the credo of Breton has often been criticized too strict and moralistic. But his fundamental belief on the total liberation of human being and the amelioration of the world has to be well understood. Also his missionary consciousness and humanistic stance deserve high evaluation. Andre Breton’s humanistic attitude with a historical view on the world could be a good lesson which makes us reflect on our art world where there are so many critical writings without any historical view or humanistic sense of responsibility.

This study was conducted to find out the paternal attachment to neonate, and to identify factors affecting paternal attachment. The purpose was to make the base data for nursing intervention to improve paternal attachment. The subjects of this study were 93 fathers whose partners have delivered normal neonate in 1 hospital in Busan. Data were collected from Sep. 1th to Oct. 31th 2005 by a self-report questionnaire. The instrument for this study was based on 7 kinds of characteristics of paternal attachment by Greenberg & Morris(1974), and modified by researchers. The statistical methods for data analysis were percentage, mean, standard deviation, t-test, ANOVA with SPSS program Ver 10. The conclusions are as follows. Fathers had the high degree of paternal attachment to neonate. But, there were not significant correlations between paternal attachment and the father`s demographic characteristics, pregnancy plan, delivery pattern, delivery order, sex of neonate and past experience. Also there were not significant correlations between paternal attachment and early visual contact frequency of father-neonate. Further research about factors affecting paternal attachment to neonate and high risk neonate as well as low birth weight neonate is required.
