Purpose: To assess efficacy of the Pentacam (PTC) and the anterior segment optical coherence tomography (AOCT) for detection of occludable angles. Materials and Methods: Fourty-one eyes with gonioscopically diagnosed occludable angles and 32 normal open-angle eyes were included. Anterior chamber angle (ACA) and anterior chamber depth (ACD) were measured with PTC and AOCT. Receiver operating characteristic (ROC) curve was constructed for each parameter and the area under the ROC curve (AUC) was c

With the advent of open standards for interactive TV, various interactive data services are enabled to run transparently across vendor-specific hardware platforms. With careful modular design and interfaces, a considerable amount of middleware components can be reused without or with minor modifications. In this paper, a general architecture of the middleware and its few key components for DTV receivers are introduced.

Korea and Japan hosted the FIFA World Cup Soccer Game in 2002. Ten stadiums were built and more than 30 soccer grounds for practice were renovated in Korea. Sport fields in both countries have problems on cool-season turfgrass growth and quality by summer decline during humid and warm climate especially followed by intensive uses. We measured the effects of air-flow system, which is designed to optimize rootzone soil gas and moisture levels to promote the growth and maintenance turfgrass. This e

Heparin is a well-known anticoagulant widely used in various clinical settings. Interestingly, recent studies have indicated that heparin also has anti-inflammatory effects on neuroinflammation-related diseases, such as Alzheimer’s disease and meningitis. However, the underlying mechanism of its actions remains unclear. In the present study, we examined the anti-inflammatory mechanism of heparin in cultured cerebral endothelial cells (CECs), and found that heparin inhibited the tumor necrosis fa

Abstract I estimate a matching model of business‐partnership formation to quantify the relative importance of productivity gains, financing gains, and the coordination failure of effort provision (moral hazard) among partners. Productivity gains account for 61% of the gain from the observed partnerships. For partners in the first quartile of the wealth distribution, however, financing accounts for 93% of the gain. The cost of moral hazard corresponds to 42% of the entire gain from partnerships.

Background/Aims Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder of the esophagus. Similar to asthma, EoE can induce irreversible structural changes in the esophagus as a result of chronic and persistent eosinophilic inflammation. The aim of this study was to analyse changes in symptoms, eosinophil counts and endoscopic findings after treatment. Methods Nine patients with EoE (6 men and 3 women; mean age, 36.44 years) were diagnosed with EoE based on typical symptoms, endoscopic

The tubby mouse is characterized by progressive retinal and cochlear degeneration and late-onset obesity. These phenotypes are caused by a loss-of-function mutation in the tub gene and are shared with several human syndromes, suggesting the importance of tubby protein in central nervous system (CNS) functioning. Although evidence suggests that tubby may act as a transcription factor mediating G-protein coupled receptor (GPCR) signaling, any downstream gene regulated by tubby has yet to be identi

The growth of root and shoot normally decline dramatically in mid-summer of Korea, moreover the cool-season turfgrassgrass eventually wither to death over 30oC. The increase of air temperature also drives the heat of soil, that makes stress on root system. The heat stress affects physiological mechanisms of hormonal unbalance that stimulates shoot growth, photosynthesis, and transpiration. To solve those problems, many studies have been carried out to control soil moisture and OM content to decr

목적: 라식을 시행 받은 아벨리노각막이상증(ACD)의 예를 수집, 조사, 분석하여 라식 후 ACD의 악화 기전을 추론하고, 진행을 조사하며, 치료를 시행한 경우 각 방법의 결과를 분석함으로써 악화 방지 및 치료법을 도출하고자 하였다. 대상과 방법: 2004년 1월부터 2007년 5월까지 한국백내장굴절수술학회 회원이 속한 병원에서 LASIK 수술을 받은 ACD 환자 28명(56안)을 대상으로 하여 술 전, 후 최대 교정시력, 대비감도, 각막 혼탁 등의 변화를 비교 분석하였다. 치료효과 판정을 위해 기계적 각막혼탁제거술 및 각막절편 제거술을 시행한 환자와 심층층판각막이식술(DLKP)을 시행받은 환자에서 수술 전, 후의 각막혼탁의 호전 여부, 시력, 대비감도를 비교 분석하였다. 결과: 레이저기기, 절삭기, 절편의 크기와 두께에 관계없이 라식을 받은 모든 경우에서 술 후 각막혼탁이 악화되어 시력 및 대비감도가 저하되었다. 라식 후 악화된 ACD의 치료로 시도된 DLKP는 좋은 결과를 보였다

We document a drastic increase in female-owned manufacturing firms in South Korea after the 1997 financial crisis. During the crisis, a major banking-sector reform was conducted, and many underperforming bank branches were forced to close down. Using a geographical variation of bank-branch closures during the reform, we show that the banking-sector reform resulted in a rise in female entrepreneurship. We present evidence that the closed-down bank branches preferred male-owned firms, despite fema

Singapore has completed its catch-up growth phase and needs to find a new growth engine. Entrepreneurship can contribute to a nation’s productivity growth. The purpose of this chapter is twofold. First, a theoretical framework is presented, along with empirical evidence, to understand government interventions aimed at boosting entrepreneurship. Second, using the framework, the chapter discusses whether Singapore’s current policies are suitable for helping entrepreneurship. The theory demonstrate
