광학적 사진촬영과 3D소프트웨어를 통한 이미지 제작방식연구 - 사진 연작 <상승> 작업을 중심으로 -
윤태준 한국사진학회 2024 AURA Vol.- No.52
The photographic medium primarily uses optical lenses to mechanically reproduce images onto a plane, aiming to accurately represent real objects. Recent advancements in optical and digital technology have enhanced resolution and image processing, transcending traditional photographic methods and enabling new visual representations like Machine Vision. Digital images go beyond film, necessitating software like Adobe Photoshop for post-processing. This study suggests a new approach to photographic work, distinguishing between traditional photography and digital image production. It particularly focuses on combining photorealistic image creation in 3D software. The project <Ascent> illustrates this method, merging optical imaging techniques with 3D software. It utilizes repetitive printing and enlarging photography to generate new image data, finalized through texturing and rendering in 3D software. The goal is to explore new photographic techniques, not just as replicas of reality but as images that can be assembled and blended. This is demonstrated in <Ascent>, exploring the potential of innovative photographic methods. The research aims to push the boundaries of traditional photography by integrating it with contemporary digital technology, opening up new possibilities for the photographic medium.

The purpose of this study is to analyze the influence of the development scale of the apartment complexes to the pedestrian environment for the local residents. The conflicts between the apartment block and its neighbours are occurred recently because of the increased control of the neighbours’ entries into the apartment complex. Therefore this study analyzes the relation between scale of the apartment complex and the length of the neighbours’ detour route. The results of this study are as follows: Firstly, the length increment of walking route and disenfranchised pedestrian right are the important cause of conflict. In addition, the minimum route length and detour degree arousing conflict are 456m and 1.5 degree. Secondly, there are clear positive correlations between the scale of the apartment complex and the length of the neighbours’ detour route. Thirdly, the length of the border in-between the destination facility and the apartment block is important cause of detour.

This study was conducted to confirm the relationship between the proactive accounts receivable management of SMEs on credit sales decision making and business performance, and to derive effective accounts receivable management plan and systematic credit sales decision making plan. Based on 455 copies of data collected through a survey targeting SMEs, it was confirmed through factor analysis, reliability analysis, confirmatory factor analysis, and model fit verification, and the research hypothesis was verified with a structural equation model. As a result of the verification, credit rating had a positive effect on financial performance, sales performance and credit sales decision, while credit control had a positive effect on financial performance, while negative effect on sales performance and credit sales decision. In the mediating effect hypothesis test, credit sales decision had a positive effect between credit rating and business performance and a negative effect between credit control and business performance. The study suggests that if small and medium-sized enterprises improve their business performance through effective accounts receivable management, they can create a synergistic effect in enhancing the business performance of companies if they simultaneously improve their proactive accounts receivable management and credit sales decision ability. Future research is required to study the impact of factors such as segmentation of research subjects and credit transaction motives and accounts receivables management. 본 연구는 중소기업의 사전적 매출채권관리가 신용판매의사결정과 경영성과에 미치는 영향관계를 확인하고 효과적인 매출채권 관리방안과 체계적인 신용판매의사결정 방안을 도출하기 위해 실시하였다. 중소기업을 대상으로 설문조사를 통해 수집된 455부의 자료를 바탕으로, 요인분석 및 신뢰성분석, 확인적 요인분석, 모형 적합도 검증을 통해 확정하고, 구조방정식모형으로 연구가설을 검증하였다. 검증 결과 신용평가는 재무성과와 영업성과 및 신용판매의사결정에 정(+)의 영향을, 신용통제는 재무성과에 정(+)의 영향을 미친 반면 영업성과와 신용판매의사결정에는 부(-)의 영향을 미쳤다. 매개효과 가설검증에서 신용판매의사결정은 신용평가와 경영성과 간에 정(+)의 영향을, 신용통제와 경영성과 간에는 부(-)의 영향을 미쳤다. 연구는 중소기업이 효과적인 매출채권관리를 통해 경영성과를 제고하기 위해서 사전적 매출채권관리와 신용판매의사결정 능력의 향상을 병행한다면 기업의 경영성과 제고에 시너지 효과를 발생시킬 수 있음을 시사한다. 향후 연구대상의 세분화 및 신용거래동기 등 요인과 매출채권관리와의 영향 연구가 요구된다.

Lectin-like oxidized low-density lipoprotein (LDL) receptor 1 (LOX1) binds to oxidized LDL, which is associated with inflammationin various vascular disorders. Here, we aimed to investigate the potential of soluble LOX1 (sLOX1) as an indicator of antineutrophilcytoplasmic antibody-associated vasculitis (AAV) activity. Serum levels of sLOX1 in frozen samples from patients withAAV enrolled in a prospective observational cohort study at the Severance Hospital were measured using enzyme-linked immunosorbentassay. Clinical and laboratory data were collected on the date when the blood sampling was performed. The associationbetween sLOX1 and clinical and laboratory data was assessed using Pearson’s correlation analysis. The median age of the recruited79 patients was 62.0 years, and 27 (34.2%) patients were men. The median Birmingham vasculitis activity score (BVAS),five-factor score, vasculitis damage index, and sLOX1 level were 6, 1, 3, and 911.9 pg/mL, respectively. Correlation analysis basedon BVAS revealed that sLOX1 and total cholesterol were significantly inversely correlated with BVAS (r=-0.224, p=0.047 and r=-0.424, p<0.001, respectively). No significant correlations were observed between continuous variables and sLOX1 except forBVAS, although total cholesterol tended to correlate with sLOX1 (r=0.190, p=0.093). Additionally, sLOX1 was not influenced by sex,hypertension, diabetes mellitus, or the presence of pulmonary, cardiovascular, and renal involvement of AAV. In summary, sLOX1was inversely correlated with BVAS in AAV patients, which is different from other vascular diseases or inflammatory diseases.
2P-479 Field effect transistor를 이용한 열전현상에 의한 ZnO nanoparticles의 계면에서의 carrier이동에 대한 연구
윤태준,박병남 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
열전 현상은 온도구배에 의한 carrier의 확산이라는 단순한 현상이지만, 이 현상을 통해 carrier의 이동 특성에 대한 다양한 특성을 관찰할 수 있다. Carrier의 이동 특성을 관찰하기 위해서는 carrier의 이동을 조절할 수 있는 Field Effect Transistor (FET)를 이용할 수 있다. 이 실험에서는 Ultra Violet (UV)을 조사하여 carrier concentration을 변화하는 ZnO nanoparticles의 성질을 이용하여 계면에서의 carrier이동 특성을 FET를 이용하여 관찰하였다.
