영화 <내 고향>과 <용광로>를 통해 본 초기 북한영화의 특징

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.

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.

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.

We used five adult dog mandibles embedded in resin block and six different cross-sectional planes for each mandible were choosen. According to the angle of mandibular occulsal plane to vertical plane(mandibular angle)and gantry angle of CT machine, we classified 4 experimental groups and 1 control group. The control group images were taken at the mandibular angel 0˚and gantry angle 0˚. The experimental images were taken at the mandibular angle 15˚and gantry angle 0˚(group 1);30˚and 0˚(group 2);15˚and 15˚(group 3);30˚and 30˚(group 4), respectively, Using the reformatted cross-sectional images, the distance from the mandibular canal to the alveolar crest and the distance from the mandibular canal to the buccal cortex and to the lingual cortex was measured and compared. The obtained results were as follows; 1. The distance from the mandibular canal to the alveolar crest of group 1 and 2 was larger than control group, but the distance of group 3 and 4 was smaller. The distance from the mandibular canal to the buccal cortex and to the lingual cortex of all experimental groups was smaller than control group. 2. The distance from the mandibular canal to the alveolar crest showed the largest difference from control group in all experimental groups, especially in group 2 and 4(p<0.05)> 3. In the distance from the mandibular canal to the alveolar crest, the number of deviation value under 1mm was 20 in group 3 and was 11 in group 2 and 4, respectively. 4. The deviation value of the distance from the mandibular canal to the buccal cortex and to the lingual cortex was under 1 mm in most cases.

연구목적 : 세포의 면역 기능 조절에 관여하는 CTLA-4의 유전자 다형성을 분석하여 주요 우울장애와의 면역 유전학적 관련성을 알아보고자 하였다. 방 법 : DSM-Ⅳ진단 기준에 따라 주요 우울장애로 진단된 환자 77명을 선정하였으며 가톨릭대학교 의과대학 조혈모세포은행에서 보유하고 있는 149명의 정상 한국인 자료를 대조군으로 사용하였다. 전혈에서 DNA를 추출하였으며 중합효소반응으로 CTLA-4유전자 exon 1 부위를 증폭한 후 SSCP방법으로 유전?? 형별 분석하였다. 결 과 : 대조군과 주요 우울장애 환자군 사이의 CTLA-4 유전자형과 대립유전자의 발현 빈도를 비교시 유의한 차이가 없었다. 결 론 : 본 연구 결과 exon 1 CTLA-4 유전자형 및 대립유전자의 발현빈도는 주요 우울장애 환자군과 정상 대조군 사이에 차이가 없어, exon 1 영역은 후보 유전자로서의 가능성이 없었다. 향후 연구에서는 다양한 변인들에 따라 대상군을 임상적으로 동질성을 지닌 집단으로 세분하여 조사대상 유전자와의 관련성에 대한 연구가 이루어져야 하겠다. Objectives : This study was carried out to explore the relationship between major depressive disorder and CTLA-4 which is related to the immunologic function such as T cell regulation. Methods : Among the korean patients diagnosed as major depressive disorder according to DSM-Ⅳ, 77 patients without neurological illness, hormonal disorder, or comorbid mental illness were selected. The stored data of 149 normal Koreans from the Catholic Hemopoietic Stem Cell Bank of Korea, were used as a normal control group. The data of Korean control group were compared with those of the studies of different ethnics. DNA was extracted from whole blood and the exon I region of CTLA-4 gene was amplified by polymerase chain reaction. Gene typing was performed by using SSCP and then, the results were assessed. Results : There were no significant differences in genotype frquencies of CTLA-4*G/G, CTLA-4*G/A, and CTLA-4*A/A between the patients with major depressive disorder and the control group in Korean population(48.1% vs 46.3%, 41.6% vs 39.6%, 10.3% vs 14.1%, respectively).There were no significant differences in allelic frequencies of CTLA-4*G and CTLA-4*A between the patients with major depressive disorder and the control group in Korean population(68.8% vs 66.1%, 31.2% vs 33.9%, respectively). Conclusion : Considering negative result for the association of the exon I polymorphism of CTLA-4 gene with major depressive disorder in this study, the exon I polymorphism does not appear to be possible candidate gene for major depressive disorder. Moreover, further systematic researches including diverse clinical variables would required.
