Purpose: The use of pre- and intraoperative vitreous bevacizumab injection and combined lens extraction with vitrectomy in patients with proliferative diabetic retinopathy (PDR) is increasing. In this study we analyzed the incidence and risk factors of neovascular glaucoma (NVG) after vitrectomy for PDR.<br /> Methods: Patients who underwent vitrectomy for PDR from January 2004 to June 2011 were retrospectively reviewed. The minimum follow-up was 12 months. The cumulative incidence of NVG was calculated using the Kaplan-Meier survival analysis. The patients were divided into 4 groups according to lens status (preoperative pseudophakic group, simultaneous cataract surgery group, sequential cataract surgery group, non-cataract surgery group). The differences in incidence between the groups were determined by the Chi-square test. Finally, to analyze the risk factors associated with the occurrence of NVG, the Cox's regression model was used.<br /> Results: Of the 614 eyes (402 patients), 284 were males and 330 were females. The mean age was 55.8 ± 10.46 years (range 30-81 years) and the mean follow-up period was 36.6 months (range 1-93 months). Thirty-four of 614 patients (5.5%) developed postoperative NVG after vitrectomy. The probability of NVG occurrence at 6 and 12 months after vitrectomy was 0.7% and 2.5%, respectively. The incidence between the 4 groups did not show a statistically significant difference. The risk factors for postoperative NVG were male gender (RR = 3.01 p = 0.004), preoperative intravitreal bevacizumab injection (RR = 7.20, p < 0.001), and reoperation (RR = 3.18, p = 0.0037).<br /> Conclusions: The frequency of NVG after vitrectomy in patients with PDR was 5.5%. Lens status was not associated with NVG occurrence. The risk factors related to NVG were male gender, preoperative intravitreal bevacizumab injection, and reoperation.<br /> J Korean Ophthalmol Soc 2013;54(12):1868-1874

EFDC모형을 이용한 새만금호 내 해수유통량에 따른 오염물질 혼합 변화 모의

The EFDC (Environmental Fluid Dynamics Code), a numerical model for simulating three-dimensional (3D) flow, transport, and biogeochemical processes in surface water systems including rivers, reservoirs, and estuaries, was applied to assess the effect of sea water and fresh water exchange rates ($Q_e$) on the mixing characteristics of a conservative pollutant (tracer) induced from upstreams and salinity in Saemangeum Lake, Korea. The lake has been closed by a 33 km estuary embankment since last April of 2006, and now seawater enters the lake partially through two sluice gates (Sinsi and Garyuk), which is driving the changes of hydrodynamic and water quality properties of the lake. The EFDC was constructed and calibrated with surveyed bathymetry data and field data including water level, temperature, and salinity in 2008. The model showed good agreement with the field data and adequately replicated the spatial and temporal variations of the variables. The validated model was applied to simulated the tracer and salinity with two different gate operation scenarios: RUN-1 and RUN-2. RUN-1 is the case of real operation condition ($Q_e=25,000,000\;m^3$) of 2008, while RUN-2 assumed full open of Sinsi gate to increase $Q_e$ by $120,000,000\;m^3$. Statistical analysis of the simulation results indicate that mixing characteristics of pollutants from upstream can be significantly affected by the amount of $Q_e$.

미술관 전시디자인의 정치적 활용에 관한 연구 - MoMA의 《승리에 이르는 길》을 중심으로 -
정희영 ( Chung Hee-young ) 커뮤니케이션디자인학회 2024 커뮤니케이션 디자인학연구 Vol.87 No.-
During the Great Depression, the U.S. government channeled its efforts towards raising public awareness of rural poverty and urban unemployment, and to advocating for the effectiveness of the Farm Security Administration (FSA) initiatives under the New Deal. In alignment with the movements, the FSA created an archive of documentary photographs. With the U.S. entering World War II in 1942, the archive was repurposed to organize a large-scale photography exhibition aimed at legitimizing the war and fostering nationalist sentiment. The current paper examines the exhibition, Road to Victory, curated in 1942 by Edward Steichen, who served as Director of the Department of Photography at the Museum of Modern Art in New York (MoMA) from 1942. This exhibition warrants thorough inspection as it laid the groundwork for subsequent politically-driven photography exhibitions at MoMA, and Herbert Bayer, a leading figure in avant-garde exhibition design in Europe, implemented its spatial and visual design. Considering Bayer’s inclination towards exhibition design that center on viewer perspective and consciousness, this paper analyzes the ways in which the content of Road to Victory embodies political discourse within the context of exhibition design.
