1930년대 모더니즘과 도시시학

김동우(Kim Dong-Woo) 국어국문학회 2008 국어국문학 Vol.- No.149

This essay intends to explain the meaning of Korean modernism poetry and the poetics focusing on the urban space in which the modern age and modernity are realized and exhibited concrete place. This discussion generally has two subjects which are the poetic perception for urban and of the issue of the expression. The main point of Intellectualism, a branch of Korean modernism, is having a scientific and intellectual attitude for understanding the modern society. This has a positive meaning. Because of aiming the modern attitude of understanding the world and more definitely functioning a instrumental tool for perception and criticism of urban civilization which develops complicatedly. This is significant to understand the life-style of the urbanites objectively, considering city dwellers feel at over-sensitiveness that makes intellectualization of urban life eventually by reason of the own doublefaced character of urban and its complex artificial mechanism. But, on occasion that the attitude of perception changes to the issue of the expression the limit is revealed clearly. Because the liberated practice of intellectualized life is obtained in the opposite factor of it instead. In that respect Kywang-Kyun Kim‘s poetic art of formation attracts an attention. He was good at forming the urban image and lyric. The favorable comments for his commanding the image and unfavorable ones for his expressing the excessive feeling were the dominant existing criticisms. But, in relation to urban life, the lyric of his poems doesn't melted into the images fully call forth tragic beauty that stimulate alienation and sorrow of urbanite more strongly. For this reason Kywang-Kyun Kim's poem should be newly evaluated. And the synesthesia expressions reveal a new respect in connection with segmentalized and fragmental urban life-style. After all, his poem helps to recover man's totality through the integration of sense.

We have developed a new device, Plate-to-CCD Convertor (PCC), to conveniently digitize photographic plates in a relatively short time without losing any plate information (Oh et al. 1995). Using this device we have performed surface photometry of 12 early type galaxies. We determined relative orientations and scales to analyze PCC images. We also determined an ellipticity, position angle of the major axis, and $a_4$ of each galaxy to quantify the distribution of surface brightness. We checked the performance and limitation of this device by comparing the PCC images with those digitized by the ST microdensitometer and those obtained with CCD observations.

Objectives : This study was aimed to elucidate the effects of Trichosanthes kirilowii extract (TKE) on the angiogenesis and growth of tumor cells. Methods : Tube formation assay was performed by using human umbilical vein endothelial cells (HUVEC), and anchorage dependent colony assay was performed by using B16-F10 melanoma, Hep G2 and HT1080, CT-26 and SNU-1 cells. Results : For HUVEC, TKE at a level of more than 100 ${\mu}g/m{\ell}$ suppresses cell growth. For HUVEC at 100 ${\mu}g/m{\ell}$ and greater TKE density, the formation of tubes was suppressed in a dose-dependant manner. TKE controls the colony formations of B16-F10 melanoma cells, CT 26 cells, and Hep G2 cells, and its effect is proportional to density. In HT1080 cells and SNU-1 cells, formation is suppressed regardless of density. Conclusions : From these results, it could be concluded that TKE has significant properties on anti-angiogenesis and growth inhibiting of tumor cells. It is suggested that TKE will be a good candidate for new drugs or therapeutics for anti-angiogenesis.

김동우,홍광표,조명우,이은상,Kim, Dong-Woo,Hong, Kwang-Pyo,Cho, Myeong-Woo,Lee, Eun-Sang 한국생산제조학회 2010 한국생산제조학회지 Vol.26 No.2

Recently, the magnetorheological (MR) polishing process has been examined as a new ultra-precision polishing technology for mirror surface generation in many applications, such as aspheric lenses, biochips, micro parts, etc. This method uses MR fluids which contains micro abrasives as a polishing media, and can. It is possible to obtain nano level surface roughness under suitable process conditions, however, required polishing time is highly dependent on the applied pre-polishing methods due to its very small material removal rate. Thus, in this study, a combined polishing method is presented to reduce total polishing time for SUS304. First, the electropolishing (EP) method was applied to obtain fine surface roughness, and the MR polishing was followed. Surface roughness variations were investigated according to the process conditions. As the results of this study, it was possible to reduce total polishing time for SUS304 using the proposed combined polishing method.

김동우,박대송,이상칠,김성용,임호용,염학열,김현민,Kim, Dong-Woo,Park, Dae-Song,Lee, Sang-Chil,Kim, Sung-Yong,Lim, Ho-Yong,Yeom, Hak-Yeol,Kim, Hyeon-Min 대한악안면성형재건외과학회 2011 Maxillofacial Plastic Reconstructive Surgery Vol.33 No.6

Purpose: Patients who had a subcondylar fracture with a displaced or deviated condylar segment were treated with a retromandibular approach (RMA) or an endoscope-assisted transoral approach (EATA) in our department of oral and maxillofacial surgery. The clinical results of the approaches were compared. A comparative study of specific approaches for subcondylar fractures has not been published before in Korea. Methods: Twenty-one patients with subcondylar fractures of the mandible were included. Ten patients were treated with the retromandibular approach and 11 were treated with an endoscope-assisted transoral approach. We examined patient age, gender, fracture sites, classifications, period of maxillomandibular fixation, facial nerve (FN) or greater auricular nerve (GAN) injuries, maximal mouth opening, deflection, occlusal changes, number of plates, follow-up period, and other complications. Preoperative computed tomography and pre-operative, post-operative, and follow-up panoramic views were taken of each patient. Results: Mean maximal mouth openings were similar between the two approaches. FN and GAN injuries were more frequent in the RMA group but the deflective rate with mouth opening was higher in the EATA than that in RMA group. Two cases of post-operative infection occurred in the EATA group, and occlusal changes were observed in one case for both approaches. Conclusion: The RMA offers more direct access and visualization of the surgical field but it can cause scars and retractive injuries of the FN and GAN. But, EATA did not result in consequent nerve injuries or scars postoperatively, but unfavorable fractures such as $medial$ $override$ condyles were more difficult to reduce endoscopically. Except cases of an expected difficult reduction, the treatment of choice for a displaced subcondylar fracture may be an EATA.

대동맥판(大動脈瓣) 폐쇄불전증(閉鎖不全症)으로 흉통(胸痛)을 호소하는 태음인(太陰人)환자의 가미조리폐원탕(加味調理肺元湯) 치험례

Aortic regurgitation occurs when there is a leakage of the valve backward into the left ventricle during diastole. Chronic aortic regurgitation may be present for decades before any symptoms occur. The left ventricle is able to compensate for the large volume of blood that flows backward by enlarging the cavity and increasing the thickness of the muscle. This mechanism allows the heart to pump out both the amount of blood required by the body and the blood that has gone backward into the left ventricle. One patient who had chest pain from exercise was treated. He was diagnosed with aortic regurgitation LVH by echocardiography. Signs showed him to be of Taeumin-type within Sasang Constitutional Medicine. He was prescribed Gamijoripewontang for 75 days, and improvement of clinical symptoms were observed. Results support prescription of Gamijoripewontang as an effective treatment for Taeumin-type patients suffering chest pain caused by aortic regurgitation.
