`Purpose: To evaluate differences between partial coherence laser interferometry (IOL-Master, Zeiss) and A-scan measurement of axial length and anterior chamber depth in silicone oil-filled eyes according to viscosity. Methods: Using IOL-Master and A-scan, axial length and anterior chamber depth in silicone oil-filled eyes (n=54) and normal eyes (control, n=54) were measured and analyzed. In silicone oil-filled eyes, calculated axial lengths by A-scan using conversion factors, axial length multiplied by 0.71, and vitreous cavity multiplied by 0.64 (classic method) were compared with those calculated by IOL-Master. Anterior chamber depths were also analyzed., and axial lengths and anterior chamber depths were compared according to the viscosities of silicone oil for measurement by A-scan. Results: Axial length and anterior chamber depth using IOL-Master were shorter than those using A-scan by 9.45±1.81 mm (p<0.05) and 0.11±1.29 mm, respectively. In normal eyes, axial length and anterior chamber depth using IOL-Master and A-scan were not significantly different. In silicone oil-filled eyes, axial length using IOL-Master and conversion factor was also not significantly different. At the highest silicone oil viscosity the difference in measured axial length was greatest (p<0.05) while the difference in anterior chamber depths was smallest. Conclusions: In silicone oil-filled eyes, axial length by IOL-Master was more accurate than that by A-scan, regardless of silicone oil viscosity. Thus, IOL-Master is more useful than A-scan when measuring axial length in silicone oil-filled eyes.`
재사용 및 재활용에 적합한 환경가구디자인에 관한 연구 - 마네킹(Maneking)을 이용한 스트리트 퍼니처(Street Furniture) 디자인을 중심으로 -

This study focused on designing environment-friendly furnitures by recycling useless stuffs. I designed environment-friendly furnitures by using plastic manekings, which do not decay easily. Designing environment-friendly furnitures by using maneking, we should consider the following; to make our surrounding comfortable and pleasant, to make the appearance of the streets more beautiful, and to consider our future environment. We need to use reusable and recyclable wastes much more to make environment-friendly furnitures from now on.

코로나 19 팬데믹으로 비대면 문화가 사람들의 일상에 녹아들면서 메타버스에 대한 관심도 크게 증가하였다. 메타버스는 목적에 따라 여러 형태가 존재한다. 메타버스에 대한 관심도 와 수요가 최근 급증하면서 다양한 메타버스 산출물의 개발과 공급이 진행되고 있지만, 산업체 개발자들이 참고할 수 있는 실질적인 산업체 친화적인 메타버스 콘텐츠 개발 가이드라인이 없어 개발에 많은 어려움이 있다. 본 연구에서는 다양한 메타버스의 유형 중 게임형 메타버스 콘텐츠들을 비교 분석함으로써 개발자들이 게임형 메타버스 콘텐츠를 개발할 때 참고할 수 있는 개발 가이드라인을 작성하고자 한다. 개발 가이드라인에서는 대표적인 게임형 메타버스 플랫폼들의 공통되는 특징적 요소들을 정리하고 해당 요소들을 어떻게 개발해야하는지에 대하여 설명을 첨부하였다. 특징적 요소 도출 및 설명 첨부 이후 관련 전문가들을 대상으로 진행한 설문조사를 통해 개발 가이드라인의 적절성을 검증하였다. As non-face-to-face culture melts into people's daily lives due to the COVID-19 pandemic, interest in the metaverse has also increased significantly. There are several types of metaverse depending on the purpose of applications. With this recent explosive interest in the metaverse platform and demanding applications on it, there have been various contents for metaverse in progress in industries. However, developing such contents has many real problems since there is no valuable guidelines for metaverse contents development in industry. In this study, we aim to propose a development guideline that developers can refer to for game-type metaverse content by comparative analysis of existing contents among various metaverse types. In the development guideline, we derive common characteristic components of representative features for game-type metaverse platforms and give explanations on developing strategies. Such proposed development guidelines are verified by game-type metaverse field experts by survey.

Purpose: To evaluate the short-term effect of intravitreal bevacizumab (Avastin<sup>Ⓡ) in polypoidal choroidal vasculopathy. Methods: Intravitreal Avastin<sup>Ⓡ was injected into 13 eyes of 13 patients with PCV in this retrospective, interventional case study. The follow-up period lasted over 3 months after therapy. Changes in best-corrected visual acuity (BCVA), foveal height determined by optical coherence tomography, and abnormal vasculature in indocyanine green angiography (ICGA) were evaluated. Results: The mean LogMAR BCVA was 0.82 at baseline, 0.78 at 1 month after treatment, and 0.73 at 3 months after treatment. Visual acuity was stabilized or improved in 13 eyes (100%). The mean foveal height was 288 μm at baseline, 231 μm (p<0.05) at 1 month after treatment, and 196 μm at 3 months after treatment. The polypoidal lesions in ICGA decreased in 4 eyes (31%), although branching vasculature in ICGA was unchanged in 13 eyes (100%). Conclusions: Intravitreal injection of Avastin<sup>Ⓡ may stabilize visual acuity and reduce macular edema due to decreased retinal pigment epithelial detachment and leaking. However, intravitreal injection had a minimal effect in occlusion of the symptomatic polypoidal lesions and no effect in occlusion of the branching vascular network.
