참여적 자화상으로서의 인물사진 : Being a Queen, Face of Face 시리즈를 중심으로
천경우 ( Chun¸ Kyungwoo ) 현대사진영상학회 2021 현대사진영상학회논문집 Vol.24 No.2
The requirements for portrait photography are premised on the fact that the photographer and the subject are together in one space. In other words, a photographic image is formed as a single overall result through small and large interactions and empathy in space and time where the photographer and the subject person coexist. The two photographic series to be introduced in this article both have the structure of the process of acting (performance) and the image as their result. And the process of making a photo is not aimed at capturing any moment or finding and recording the characteristics of a person, and the conditions for who the subject will be are given regardless of their appearance. Rather, it is made up of voluntary ‘choice’ and ‘participation’ by those who want to understand and participate in the conditions given by the artist, and as a result of their act of participation, the characters ultimately experience the way they see themselves. The author sees these processes and technical conditions as the meaning of ‘self-portrait as participation’. In this paper, Korean and foreign theorists introduced and interpreted the process from the conception stage to the production process and exhibition in Europe and Korea of the project Being a Queen (2007/2009) realized in Denmark and Face of Face (2016) produced in Korea. I would like to present the expanded possibilities of photographic expression of how people in front of the camera look at themselves, along with examples of their perspectives, as well as the participatory act, the perception of time in it, and how the people in front of the camera view themselves.

Purpose: To investigate the baseline characteristics in patients with diabetic macular edema (DME) during 7 years according to the need for additional treatments after intravitreal ranibizumab (RBZ) loading injections. Methods: The medical records of 32 patients treated with intravitreal RBZ loading for DME during 7 years were reviewed. After three-consecutive monthly RBZ injections, additional treatment was decided according to the patient’s response to RBZ loading. Based on whether the patients received treatment with or without additional injections, including intravitreal antivascular endothelial factor or steroid injection, they were divided into the “no add (NA)” or “add” groups, respectively. The baseline best-corrected visual acuity (BCVA), macular volume (MV), central subfoveal thickness, and other clinical factors were analyzed, and their 7-year changes were compared between the two groups. Results: The BCVA of the NA group was better than that of the add group at 2, 3, 5, and 7 years (year 2, 3, and 5; p < 0.01, respectively). Baseline MV was significantly smaller in the NA group than in the add group (10.72 ± 0.88 μm vs. 11.98 ± 1.64 μm, p = 0.008). The DME duration before treatment in the NA group was significantly shorter than in the add group (1.03 ± 0.98 years vs. 1.91 ± 1.33 years, p = 0.042). The proportion of patients with serous retinal detachment or cystic macular edema was significantly lower in the NA group than in the add group (35.3% vs. 73.3%, p = 0.042). The NA group had smaller MV until 2 years than the add group (year 1, p = 0.002; year 2, p = 0.006). Conclusions: The DME patients without additional treatments during 7 years after the initial loading treatment had shorter duration of DME and diffuse retinal thickening morphologic type with lower MV at baseline, and better long-term visual prognosis.
Effects of Disasters on Local Climate Actions: Climate Change Mitigation and Adaptation Actions
( Kyungwoo Kim ) 한국정책학회 2018 한국정책학회 동계학술발표논문집 Vol.2018 No.-
This study investigates the effects of natural disasters on municipalities’ climate change policies. Although most theoretical frameworks on policy adoption highlight the roles of extreme events as exogenous factors influencing policy change, most studies tend to focus on the effects of extreme events on policy change at the national level. Additionally, the existing theoretical frameworks explaining local policy adoption and public service provision do not pay attention to the roles of extreme events in local governments’ policy choices. To fill those gaps, this study explores the roles of natural disasters on municipal governments’ climate change policies. It does this by applying the theory of focusing events to local climate mitigation and adaptation actions. Based on the framework, this dissertation develops and tests hypotheses to examine the effects of natural disasters on municipalities’ climate mitigation and adaptation policies. The study uses 2010 National League of Cities (NLC) sustainability surveys and the 2010 International City/County Management Association (ICMA) sustainability survey to test the hypotheses. Analytical results show that floods and droughts influence local climate change policies and suggest that local governments can take advantage of extreme events when initiating a policy change.
Genetic Characteristics of Sasang Typology: A Systematic Review
Kyungwoo Sohn,채한,정안숙,Miyoung Yoon,Sunkyung Lee,Sang-MoonHwang 사단법인약침학회 2012 Journal of Acupuncture & Meridian Studies Vol.5 No.6
A systematic review on studies related to the genetic characteristics of Sasang types was conducted with the goal of delineating genetic characteristics of Sasang typology. Six electronic databases of up to the March 2011 were examined with the key words of Sasang typology, constitution, and genetics in both Korean and English. Predefined review criteria were used, including demographic characteristics, type classification methods, genotyping methods, and genotypes. Fifty-nine potentially relevant studies were identified and 40 peer reviewed research articles that contained genetic data were included. Fourteen articles reported statistically significant differences among Sasang types, which are heritability, structural variation, genome-wide screening, and pathophysiological function. Although significant genotypes were reported with vWA, CSF1PO, Penta D, HLA-Cw*04, HLA-Cw*07, PPAR-γ, MDR1, IL-α, IL-β, and IL-6 receptor, results of the review indicate that there was no conclusive genotype related to the Sasang typology. Considering the features of Sasang typology, it is recommended that the macroscopic systems medical approach on genetics be employed, rather than the single genes association approach.
The pressure-gradient system and semi-hyperbolic patches of solutions
Kyungwoo Song,Yuxi Zheng 한국산업응용수학회 2008 한국산업응용수학회 학술대회 논문집 Vol.4 No.3
We introduce a pressure-gradient system derived from the two-dimensional compressible Euler system and we construct patches of solutions of the 2-D Riemann problem for the pressure-gradient system. In the self-similar plane to the system, we verify that there are elliptic regions, hyperbolic regions, and sonic boundary parts. In addition, it is also verified that there is a zone called semi-hyperbolic or partially hyperbolic in which one family out of two nonlinear families of characteristics starts on sonic curves and ends on transonic shock waves.
Antimicrobials, Gut Microbiota and Immunity in Chickens
Kyungwoo Lee,Hyun S. Lillehoj 韓國家禽學會 2011 韓國家禽學會誌 Vol.38 No.2
The use of antimicrobials will be soon removed due to an increase of occurrence of antibiotic-resistant bacteria or ionophore-resistant Eimeria species in poultry farms and consumers’ preference on drug-free chicken meats or eggs. Although dietary antimicrobials contributed to the growth and health of the chickens, we do not fully understand their interrelationship among antimicrobials, gut microbiota, and host immunity in poultry. In this review, we explored the current understanding on the effects of antimicrobials on gut microbiota and immune systems of chickens. Based on the published literatures, it is clear that antibiotics and antibiotic ionophores, when used singly or in combination could influence gut microbiota. However, antimicrobial effect on gut microbiota varied depending on the samples (e.g., gut locations, digesta vs. mucosa) used and among the experiments. It was noted that the digesta vs. the mucosa is the preferred sample with the results of no change, increase, or decrease in gut microbiota community. In future, the mucosa-associated bacteria should be targeted as they are known to closely interact with the host immune system and pathogen control. Although limited, dietary antimicrobials are known to modulate humoral and cell-mediated immunities. Ironically, the evidence is increasing that dietary antimicrobials may play an important role in triggering enteric disease such as gangrenous dermatitis, a devastating disease in poultry industry. Future work should be done to unravel our understanding on the complex interaction of host-pathogen-microbiotaantimicrobials in poultry.
