19세기 京華世族의 實景山水畵後援배경과 畵壇에 미친 영향

金賢貞(Kim Hyunjung) 미술사연구회 2009 미술사연구 Vol.- No.23

Real-scenery landscape paintings (silgyeong sansuhwa, 實景山水畵) in the nineteenth century were produced in various forms such as albums, scrolls or folding screens, since patronage for the real-scenery landscape paintings by gyeonghwasejok had expanded due to travel for exploring natural beauties and their interest in collecting paintings and calligraphies. Gyeonghwasejok refers to aristocrats (yangban) living in the nation’s capital whose families’ social and economic status were guaranteed by monopolization of their government official posts. Gyeonghwasejok was a patron to painters, as well as a collector with the power of controlling the art market. Gyeonghwasejok, who dominated the painting circles in the nineteenth century, chose jabidaeryeong hwawon (painters-in-waiting) who were regarded as the best painters in their time after Kim Hong-do or local literati painters for their commissions. Gyeonghwasejok patronized real-scenery landscape paintings in the political situation of Noron (Old Doctrine)’s in-law government in the nineteenth century because of fascination over traveling for exploring the beauty of nature and their interest in collecting paintings and calligraphies, expression of consciousness of lineage and channels for political exchange, and the increased trend of treasuring Kim Hong-do’s Haesan-cheop. Gyeonghwasejok was active in producing real-scenery landscape paintings, as they were infatuated with traveling and collecting, while reading travel poems and travel diaries of their predecessors or treasuring inherited objects related to traveling for exploring the beauties. Further, Gyeonghwasejok reproduced gajeon hwacheop (painting albums preserved in one’s family) or gajeon hwabyeong (folding screens preserved in one’s family) that revealed their consciousness of lineage, or produced travel albums of paintings to get forewords or inscriptions from high-ranking officials, so they strived to secure their political positions. This is evidenced by Gosangugok sihwabyeong commissioned in 1803 by Andong Kim’s clan, a representative Noron’s family in power, and by the fact that they commissioned a painter to remake a copy of Gokwun gugok docheop in 1804. With the increased trend of treasuring Kim Hong-do’s Haesan-choep, gyeonghwasejok accompanied jabidaeryeong hwawon their journeys to produce travel albums of paintings or commissioned painters to reproduce travel albums of paintings in Kim Hong-do’s style. Real-scenery landscape paintings in the nineteenth century were patronized by two political powers; Noron’s gyeonghwasejok, who has substantial political power, and Soron(Young Doctrine)’s gyeonghwasejok, who cooperated with a family in power. Noron’s gyeonghwasejok who settled around the capital had the power not only in political circles but in art circles as well. Noron Yi Gwang-mun (1778-1838)’s Haesan docheop is a travel album of paintings executed by Kim Ha-jong (1793-1878) for his patron Yi Gwang-mun in his distinctive manner, which did not follow Kim Hong-do’s Haesan-choep, but rather reflected Yi’s idea of depicting actuality. This paper confirms that Kim ha-jong, who died in 1878, had a pen name of“Sungyanggeosa,”or was called “Yeonungongyang,”and it is presumed that Kim Jeong-hee (1786-1856), who had associated with Yi Gwang-mun, left an inscription on the cover of the album. Moreover, in the nineteenth century it was very competitive to be nominated by dodanghoegwon, so Jeong Won-yong, Yi Pung-ik, Yi Yu-won of Soron could not be appointed to high-ranking official posts without the support of Noron’s family in power. Haoedo sipgokbyeong patronized by Soron Jeong Won-yong (1783-1873) in 1828 was the gajeon hwabyeong commissioned to Yi Ui-seong, aimed to elevate the Jeong clan’s prestige, which is a reproduction of Haoesanghanakgang ildaedo, which included the poems of his ancestor Jeong Yu-gil and of the hometown of the Jeong clan. Jeong Wonyong published Dongseong gyoyeojip which compiled

김현정,김충현,이중엽,권재희,황도영,김기철,Kim, Hyun-Jung,Kim, Chung-Hyon,Lee, Joong-Yeup,Kwon, Jae-Hee,Hwang, Do-Yeong,Kim, Ki-Chul 대한생식의학회 2010 Clinical and Experimental Reproductive Medicine Vol.37 No.1

목 적: 배양 환경과 동결 기술이 발달함에 따라 동결 포배의 해동-이식의 빈도가 증가하고 있으며, 신선 주기와 마찬가지로 해동-이식 주기에서도 질 좋은 배아를 선별하는 것은 임신 성공 여부를 결정하는 아주 중요한 과제이다. 본 연구는 동결 당시 포배로의 발달 속도가 임신 결과에 미치는 영향을 알아보기 위하여, 수정 후 5일 및 6일째 동결한 포배의 해동-이식 후 임신율을 비교 분석하였다. 연구방법: 2006년 1월부터 12월까지 5일째 또는 6일째 동결한 포배를 해동하여 2007년 6월까지 융해 이식한 87명, 93주기를 대상으로 하였다. 동결법은 ethylene glycol과 DMSO를 이용한 유리화 동결법을 이용하였으며, 팽창 포배는 인위적인 수축을 시행 후 동결하였다. 해동 과정은 이식 전날 시행하여 15~18시간 배양액에서 배양 후 재팽창 여부를 확인하였다. 결 과: 5일째 동결한 포배를 해동-이식한 52주기와 6일째 동결한 포배를 해동-이식한 41주기에서 환자의 나이, 이식한 배아의 수, 해동 배아의 생존율 등 임신 결과에 영향을 미칠만한 요인들의 차이는 없었다. 그러나 생화학적 임신율, 임상적 임신율, 진행 임신율, 착상율 등은 5일째 동결한 포배를 해동-이식한 주기에서 높게 나타났다. 결 론: 5일째 동결한 포배를 해동-이식했을 때의 임신율은 6일째 동결한 포배를 해동-이식했을 때의 임신율보다 2배 이상 높았으며, 이는 신선 주기와 마찬가지로 해동-이식 주기에서도 동결 전 배아의 발달 속도의 차이를 임신 성공 예측의 중요한 지표로 사용할 수 있음을 시사한다. Objectives: Likewise fresh cycle, it is also important to select right blastocysts for transfer in purpose of improving the pregnancy and implantation rates in frozen-thawed embryo transfer (ET) cycles. To investigate the relationship between the developmental velocity at the time of cryopreservation and pregnancy rates, we compared pregnancy rates between the day 5 cryopreservation group and the day 6 cryopreservation group. Methods: Transfers of frozen-thawed blastocysts which had been cryopreserved by vitrification on day 5 or day 6 were performed between January 2006 and June 2007. Ethylene glycol, DMSO, and pull and cut straws were used for vitrification and artificial shrinkage was done in expanded blastocysts. Thawing was performed on the day before transfer and thawed blastocysts were cultured in for 15~18 hrs in Quinn's blastocyct media. Blastocyst survival was assessed before transfer and post-thaw survival was defined as >50% of cells remaining intact and blastocoele re-expansion by the time of transfer. Results: Transfers of thawed blastocyst had been cryopreserved on day 5 were 52 cycles and 41 transfer cycles were cryopreserved on day 6. Patient characteristics, the number of transferred embryos and the survival rate of thawed blastocysts were not different in each cryopreservation day. But the biochemical pregnancy, clinical pregnancy, ongoing pregnancy, and implantation rate were significantly high in transfer of frozen-thawed blastocyst which were cryopreserved on day 5. Conclusions: The clinical pregnancy and implantation rate of day-5 blastocyst showed significantly higher than those of day-6 blastocyst in frozen-ET cycles. This result indicated that developmental rate of blastocyst at cryopreservation time in frozen-thawed cycle is discriminative marker of pregnancy outcome as like in fresh cycle.

All the parts of the Cedrela sinensis A. Juss., including the seeds, roots, and leaves, have been known to exert medicinal effects. The C. sinensis and its major compound, quercetin, were previously reported to exhibit the anti-inflammatory and anti-oxidative activities. However, the hepatoprotective effects of the C. sinensis leaves against the alcohol-induced oxidative stress in the HepG2 cells have not been studied. In this study, we investigated the antioxidant activities and analyzed the flavonoid contents of the C. sinensis-leaf extract (CE). The total flavonoid contents of the CE is 1,874.5 mg/100 g dry weight (DW), while the total quercetin 3-O-rhamnoside (quercitrin) contents, which was identified as the major flavonol in the CE, is 1,456.0 mg/100 g DW. In the ethanol-stimulated HepG2 cells, the CE effectively prevented the cytotoxic effect and increased the gene expression of the antioxidant enzymes, such as the heme oxygenase-1 (HO-1) and the glutathion peroxide (GPx). The level of the reactive oxygen species (ROS) production was significantly decreased in the CE-treated HepG2 cells. In conclusion, the C. sinensis extract suppressed the alcohol-induced oxidative stress in the HepG2 cells via the induced GPx and HO-1 gene expressions. It is expected the CE positive effects will likely be attributed to the flavonoids, like the quercetin, within the CE.

This paper explores meanings of a main female character in Madame Freedom (2013), a media performance of Hyo-jin Kim and Hyung-su Kim. This research investigates characteristics of the heroine in its original novel and movie; and examines what the roles of dances and media workings are respectively and what the choreographer utilizes the original works in Madame Freedom. This paper argues that the media work shows a Korean housewife``s passion, sexuality & freedom; ambivalent interpretations; and strategic reconstruction of particularity and universality. These provide a way to produce diverse interpretations by exploring complex relations of novel, movie, and media performance.

암종으로 오인된 전이 폐포횡문근육종의 세침흡인 세포소견 -1예 보고-

Fine-needle aspiration cytology (FNAC) has been used extensively in the diagnosis of metastatic malignancies. However, metastatic soft tissue sarcomas are often overlooked, primarily due to the low frequency with/ which they occur. Here, we report a rare case of metastatic rhabdomyosarcoma in both cervical lymph nodes, which was detected by FNAC. A 45-year-old woman presented with anosmia, postnasal drip, and sneezing, symptoms which had persisted for 1 month. The patient was found to have a tumorous lesion at the upper portion of the mid-turbinate, with multiple enlarged cervical lymph nodes, and this lesion was examined closely at our facility. FNA cytology smears obtained from both cervical lymph nodes revealed a high degree of cellularity, and displayed cohesive clusters with gland-like spaces, as well as single isolated cells with abundant karyorrhectic debris. The tumor cells exhibited round to oval nuclei containing fine chromatin, occasional small nucleoli, and scanty cytoplasm, or a total lack of cytoplasm. Some of the tumor cells were arranged in multinucleated forms and abundant dense eosinophilic cytoplasms, reminiscent of a rhabdomyoblast. The histological findings on the lymph nodes revealed an outstanding sinusoidal infiltration and a prominent alveolar growth pattern, interspersed with occasional typical rhabdomyoblasts. The immunohistochemical results [desmin (+), myoglobin (+), myogenin (+), pan CK (-), synaptophysin (-), neuron specific enolase (-)] supported a confirmative diagnosis of alveolar rhabdomyosarcoma. Alveolar rhabdomyosarcoma is a representative sarcoma, which typically manifests with nodal metastasis and carcinoma-like clustering. The cytopathologist should remain alert upon encountering unusual morphology, so that the possibility of this condition, although somewhat remote, should not be dismissed or overlooked.

김현정,이진이,이의경,Kim, Hyun-Jeong,Rhee, Jinn-Ie,Lee, Eui-Kyung 대한약학회 2008 약학회지 Vol.52 No.3

Stomach cancer shows the highest incidence among cancer patients in Korea and it deteriorates the patients' health-related quality of life considerably. This study measured utility weights of severe stomach cancer symptoms using VAS (Visual Analogue Scale), TTO (Time-trade Off) and EQ-5D (EuroQol-5 Dimension) methods. A survey questionnaire was developed to describe the symptoms of severe stomach cancer comprehensively and concisely using VAS, TTO and EQ-5D. A face-to-face interview was conducted for 21 cancer inpatients in a hospital and 25 non-patients. The mean utility weight is 0.498 for VAS, 0.375 for EQ-5D and 0.300 for TTO. Using VAS or TTO methods, there were no statistically significant differences between patients and non-patients while there was significant difference in EQ-5D. The utility weight with VAS and EQ-5D has shown similar trend - higher score in patient group, male and aged while it has opposite trend with TTO.

An electron beam was used to mainly utilize for polishing, finishing, welding, a lithography process, etc. Due to the high technical level of difficulty of high-power density electron beam, it is difficult to secure related technologies. In this study, research was carried out to improve the machinability by developing the vaporized amplification sheets to realize the electron beam drilling technology. Their vaporized amplification sheets were analyzed by using the measurement of chemical and composition, which is such as TGA, SEM. We analyzed micro-hole processing using a microscope. Also, the thermal characteristics of vaporized amplification sheets are highly significant for applying to high-power density electron beam technique. So, we finished the vaporized amplification sheets according to the process conditions and analyzed it according to the machining conditions of the electron beam. It was confirmed that the effect on the experimental results differs depending on the influence of the metal powder contained in the developed material.

본 논문은 자이로콥터의 유한요소 모델링과 로터의 회전에 의한 동하중을 고려한 전산진동해석을 수행하였다. 이를 위해 자이로콥터의 최종 조립된 3차원 CATIA 모델을 구축하였으며, 3차원 데이터를 바탕으로 비구조 질량을 포함한 구조진동해석을 위한 유한요소모델을 생성하였다. 실용적인 전산구조동역학 해석을 위해 상용 유한요소 해석프로그램인 MSC/NASTRAN과 자체 개발한 프로그램을 병용하여 사용하였다. 비행 중 회전하는 로터에 의해 발생하는 동하중은 상용 CFD 프로그램인 FLUENT를 이용하였다. 유체해석과 구조진동해석의 결합을 위해 자체적으로 통합 연계 시스템을 구축하였다. 3차원 구조의 효율적인 진동특성을 고찰하기 위해 모달영역에서 천이응답해석과 주파수응답해석을 수행하였다. 실제 자이로콥터의 연료조건과 비행조건을 고려하였으며, 전산해석을 통하여 고유진동, 주파수 응답 및 천이응답 특성을 고찰하였다. In this study, computational structural dynamic analyses of a gyrocopter have been conducted considering unsteady dynamic hub-loads due to rotating blades. 3D CATIA models with detailed mechanical parts we constructed and virtually assembled into the complete aircraft configuration. The dynamic loading generated by rotating blades in the forward flight condition are calculated by a commercial computational fluid dynamics (CFD) code such as FLUENT. Modal based transient and frequency response analyses are used to efficiently investigate vibration characteristics of the gyrocopter. Free vibration analysis results for different fuel and pilot conditions, frequency responses and transient responses for critical flight conditions are also presented in detail.
