정태수 ( Tae Soo Jeong ) 한양대학교 현대영화연구소 2010 현대영화연구 Vol.6 No.2

The North Korean cinema after Liberation was substantially influenced by the Soviet cinema of the time, especially films of Stalin`s regime; it generally took on what the Soviet cinema mainly comprised, such as the clear narrative structure of discerning good from evil, the creation of heroic image, the mobilization and indoctrination of the populace in association with national policies, and the cult of personality. For the establishment of the North Korean state and consolidation of its political power, the inevitably necessary subsequence was the consolidation of communist ideology, propaganda, and indoctrination of the populace. In order to make propaganda films providing idealized and heroic images of their political leader, the political narrative devices of the Soviet cinema were so dominantly employed into North Korea films of the formative period. This consequently led to the formation of the cinematic characteristics of early North Korean cinema. <Naegohyang, 1949> and <Yonggwangro, 1950> are typical of the early North Korean cinema; they all draw on the simple narrative structure, the character stereotype, and the incorporation of landscape shots into narratives that dominantly shaped the early North Korean cinema. And the absolute leader Kim Jeong-Il was the centre at which all these cinematic devices converged. The leader was described as a hero of Liberation and established as the embodiment of the Korean nation itself in the early films. This paper examines the cinematic devices employed in the two typical films that later became dominant in the politics of North Korean cinema.

박 種子油中의 C30Δ5,24-Triterpene Alcohol 및 C29Δ7,22-Sterol의 構造

鄭泰明,安守中,河奉錫 慶尙大學校 1980 論文集 Vol.19 No.1

Two kinds of sterol isolated from unsaponifiables of gourd seed oil were identified, the structure as cucurbitadienol(10α-cucurbita-5.24-dien-3β-o1, C30??5,24-triterpene alcohol) and chondrillasterol[(24R)-24ethy1-5α-cholesta-7, E-22-dien-3β-o1; C29??7,22-setrol], by infrared, mass and proton nuclear magnetic resonance spectrometry using lanthanide shift reagent. The former has not been detected in higher plants so far although the compound has been synthesized from similar compound. The latter is unusual in the plant kingdom and has hitherto been found only in several species of green algae(Chlorophyta).

정희태,정수열,최용락 東亞大學校附設遺傳工學硏究所 1996 遺傳工學硏究 Vol.- No.3

glpD와 glpE는 같은 조절 영역 하에서 121 bp 간격을 두고 역방향으로 전사되어지며, 이들 유전자 상류영역에 존재하는 하나의 CRP binding site가 두 유전자의 전사 조절에 관여함을 이미 여러 연구를 통하여 확인되어졌다. 본 연구에서는 glpD와 glpE의 조절영역이 다양한 크기로 결손된 변이주를 작성하였다. 각 변이된 promoter의 발현조절 영향을 보고자 LacZ와의 융합 plasmid를 작성하였고, β-galactosidase 활성을 측정하여 cAMP에 의한 발현조절을 검토하였다. 발현조절 특성을 확인한 결과 CRP binding site 전까지 결손이 된 변이주는 wild와 비슷한 활성이지만 CRP bin-ding site가 없어진 변이주의 경우는 promoter 활성이 크게 감소했고 cAMP에 의한 발현조절은 나타내지 않았다. 한편 CRP의 공통배열을 삽입시키면 회복이 가능하였다. glpE의 조절영역도 glpD와 마찬가지로 다양하게 결손시킨 변이주를 작성하여 promoter 조절활성을 확인한 결과 CRP binding site가 없어진 변이주의 경우는 promoter 활성이 크게 감소하였으며, 결손된 CRP 결합영역을 삽입시키니 cAMP에 의한 전사촉진이 거의 회복되어졌다. The glpD gene encoding gly-3-p dehydrogenase is essential for the aerobic growth of E. coli on glycerol or gly-3-p. The glpE gene, the function of which is unknown, is transcribed divergently with respect to glpD gene. Expression of the adjacent but divergently transcribed glpD and glpE genes is positively regulated by the cAMP-CRP complex. In this study, for a precise investigation of the functional elements in the regulatory region for transcription activation by cAMP-CRP, deletion mutation have been introducted into the regulatory region. The effect of the deletion mutant on transcriptional regulation was tested in vivo by β-galctosidase activity. Deletion mutants in the regulatory region of glpD demonstrated that the presence of the CRP-binding site resulted in an sixfold increase in promoter activity. And also deletion mutants of glpE gene demonstrated that the presence of the CRP-binding site resulted in an eightfold increase in promoter activity. Insertion of 22 bp oligomer in the deletion mutants has shown that the CRP binding site is need for maximal expression of glpD and glpE genes.

정태섭,채수천 全北大學校 附設 都市및環境硏究所 1999 都市 및 環境硏究 Vol.14 No.1

Investigation was carried out Lean burn de-NOx properties of Pt-TiO_2 dual-bed catalyst by propylene in order to get the high de NOx activity and the wide temperature window under coexistence of SO_2 and H_2O. Only metal oxide catalyst themselves had NOx conversion activity at high temperature over 400℃. Metal oxide catalysts had maximum conversion activity that CuO had 20% at low temperature of 300℃, and Al_2O_3 had 84% at high temperature of 550℃. In case of metal oxide catalysts impregnated with 0.55wt% platinum ion, Pt-ZrO_2 had max conversion activity 46% at low temperature of 300℃. Almost of catalysts impregnated with various metal ion based on titania and alumina had max coversion activity at high temperature over 500℃. Dual-bed catalysts set that Pt-TiO_2 catalyst put entrance and metal oxides put to exit, gave the results of high NOx conversion activity at wide temperature window. 0.55wt%Pt-TiO_2 +Al_2O_3 catalyst and 0.55wt%Pt-TiO_2+5wt%Cu-ZSM-5 catalyst had high NOx conversion activity of 56% and 46%, and kept up the activity over 50% at high temperature zone. Under the coexistence of SO_2 and H_2O, 0.55wt%Pt-TiO_2 +ZrO_2 catalyst had most little diminution of NOx conversion activity. 0.55wt%Pt-TiO_2 +Al_2O_3 catalyst showed the vest correlation between NOx conversion activities and propylene conversion rates as R^2=0.7097.

정헌상,강태수,박희정,정익수,이항영 한국산업식품공학회 2004 산업 식품공학 Vol.8 No.1

귀리 단백 다당체의 산업적 활용 가능성을 검토하고자 추출온도(40~60℃), 에탄올 농도(0~20%0 및 pH(5~9) 조건을 조합하여 중심합성계획법에 따라 얻은 귀리 추출물의 이화학적 특성을 분석하였다. 귀리 추출물의 수율은 6.4~17.9% 범위로 추출온도는 증가할수록 에탄올 농도는 감소할수록 증가하였고 중성일 때 보다 알칼리성이나 산성일 때 수율은 증가하는 경향을 보였다. β-glucan 및 단백질 함량은 각각 21.8~38.3% 및 23.8~29.0% 범위였고 추출온도는 낮을수록 에탄올농도는 높을수록 증가하는 경향을 보였으나 pH에 의한 영향은 없는 것으로 나타났다. 귀리 추출물 수용액은 저온 및 고농도일수록 점도가 증가하였으나 일반적으로 낮은 범위였으며, 전단속도에 따라 감소하는 의소성을 나타내었다. 본 연구결과 저농도 에탄올을 용매로 사용하여 귀리 추출물중의 단백 다당체 함량비를 조절할 수 있었고, 그 수용액 또한 식품용으로 적합한 유체 특성을 갖는 것으로 나타나 산업적인 활용가치가 높을 것으로 기대된다. To examine the utilization of the soluble proteoglucan in oats as a nutraceutical ingredient, soluble components were extracted from Oat Bran Concentrate (OBC) by varying the experiment factors such as temperature (40∼60℃), ethyl alcohol concentration (0∼20%), and pH (5∼9), and then analzed gor their compositions and viscosity. The total yield of iat solube extracts ranged between 6.4∼17.9 and the contents of β-glucan, protein, lipid, and ash in oat extracts were 21.4∼38.3%, 23.2∼29.0%, 8.3∼11.8%, and 5.9∼7.9%, respectively. The exreaction yield increased with the extraction temperature, but decreased with the alchohol concentration and pH. The β-glucan and protein contents increased with increasing temperature and decreasing ethaol concentration. However, the pH level did not influenced those contents. The viscosity of 2% oat extract solution ranged between 8.6∼83.1 cp at different share rates, showing the pseudo-plastic flow properties. Results suggested that extraction condition could be controlled the purity of β-glucan and protein and applied commercially to the large-scale process.

능동 클램프 ZVS 플라이백 컨버터의 역률개선에 관한 연구

최태영,류동균,이우석,안정준,원충연,김수석 성균관대학교 2002 학술회의지원논문목록집 Vol.2002 No.-

본 논문에서는 single-stage, two-stage 두가지 역률보상(PFC)기법을 기존의 능동 클램프 플라이백 컨버터에 적용하여 역률 개선을 하였다. 삽입된 플라이백 컨버터의 능동클램프회로가 주스위치와 보조스위치의 영전압스위칭(ZVS)을 구현하며, 스위칭 손실을 줄임으로써 고효율을 얻을 수 있고, 높은 주파수에서의 스위칭이 가능하다. 하지만 일반적으로 사용되는 다이오드정류기, 평활용커패시터에 의한 낮은 역률의 문제점이 남아있다. 본 논문에서는 300W급 능동 클램프ZVS플라이백 컨버터를 설계하여 single-stage, two-stage방식을 적용, 입력역률개선을 시뮬레이션과 실험에 의해 입증하고자 한다. This paper analyzed PFC of active clamp ZVS flyback converter by adding two method PFC (Power Factor Correction) circuit - two-stage and single-stage. The addition of active clamp circuit also provide a mechanism for achieving ZVS of both the primary and auxiliary switches. ZVS also limits the turn off di/dt of the output rectifier, reducing rectifier switching loss and switching noise, due to diode reverse recovery. As a results, the proposed converters have characteristics of the reduced switching noise and high efficiency in comparison to conventional flyback converter. The simulation and experimental results show that the proposed converters improve the input PF of 300W ZVS flyback converter by adding single-stage, two-stage PFC circuit.
