PURPOSE: To investigate capillary densities in patients with unilateral normal-tension glaucoma (NTG) and normal controls using optical coherence tomography-angiography. MATERIALS AND METHODS: We recruited 13 patients with unilateral NTG and 13 healthy controls. Optical coherence tomography-angiography was performed and pure peripapillary retinal capillary density was calculated after manually excluding large vessels and the optic disc. Paired comparison of capillary densities was performed amon

Although having the same IOP-related factors, if diurnal fluctuation is included, different results may be found on the relationship between IOP-related factors and NTG progression. Based on our results, diurnal fluctuation in IOP should be considered when IOP-related factors are studied in the future.

The effects of Dy addition on the electrical properties of BaTiO3 have been studied by analyzing equilibrium electrical conductivity as a function of temperature, oxygen partial pressure (Po2) and composition. In(Ba1-xDyx)TiO3+0.5x, the conductivity follows the -1/4th power dependence of Po2 at high oxygen activities, which supports the notion that cation vacancies are generated to compensate for Dy donors, and is nearly independent of Po2 where electron compensation prevails at a low Po2. The i

Background: Recent studies suggest an association between diabetes and increased risk of heart failure (HF). However, the associations among obesity status, glycemic status, and risk of HF are not known. In this study, we analyzed whether the risk of HF increases in participants according to baseline glycemic status and whether this increased risk is associated with obesity status. Methods: We analyzed the risk of HF according to baseline glycemic status (normoglycemia, impaired fasting glucose

High-temperature electrical conductivities and leakage current behaviors of Dy-doped, and Dy and Mn codoped BaTiO3 were investigated as a function of Ba/Ti ratio. Dy-doped BaTiO3 specimens showed higher leakage currents under a continuously applied dc field stress at 150°C than undoped BaTiO3. The highest initial leakage current was observed with Ba(Ti0.98Dy0.02)O2.99. The equilibrium electrical conductivity of Ba(Ti0.985Dy0.01Mn0.005)O3 is proportional to Po2-1/4 in the n-type region, and Po2+1

이 논문에서는 데리다의 시적 환대 개념을 살펴본다. 환대란 우리 자신과 다른 사람과 관련한 에토스라는 점에서 데리다는 윤리나 문화 그 자체라고 정의한다. 여기서 데리다는 조건적 환대와 무조건적 환대로 구분한다. 절대적이고 과장법적인 무조건적 환대의 법은 이름도 묻지 않고 대가도 바라지 않는 현실적으로는 불가능한 것이고 상대적이고 관용적인 조건적 환대의 여러 법은 구체적 권리와 의무관계에 따라 조건적인 것이다. 그러나 두 환대 사이에 아포리아가 있다. 두 환대는 서로 동시에 포함하면서 배제하고, 현실적 법들은 절대적 법에 영감을 받기 때문이다. 아포리아를 다루는 데리다의 방식에서 시적 해답이 있다. 데리다는 환대의 아포리아를 넘어설 것을 요구한다. 환대의 행동은 과장법적 환대와 관용적 환대 사이에 새로운 영역을 만들어 가는 시적 과정이다. 데리다가 말했듯이 "환대는 오직 시적으로만 가능하다." 환대에 대한 이러한 데리다적 비전을 우리는 시적이라 부를 수 있다.

In glaucomatous eyes with PPRS, the increase in PPRS temporally correlated with glaucoma progression. Possible glaucoma progression may be considered around the time of increase and de novo development of PPRS.

Purpose: To compare the local distribution of prelaminar and neuroretinal rim (NRR) thickness between eyes with nonarteritic anterior ischemic optic neuropathy (NAION) and normal tension glaucoma (NTG) using enhanced depth imaging spectral-domain optical coherence tomography (OCT). Methods: This cross-sectional study included pairs of NAION and NTG patients, and controls. We measured the central prelaminar thickness; Bruch's membrane opening (BMO)-horizontal (HRW), minimal (MRW), and vertical ri
