A 50-year-old female was referred to our clinic with visual disturbance, hyphema and increased intraocular pressure (IOP) in her right eye 7 days after experiencing blunt trauma in that eye. She had undergone uncomplicated laser in situ keratomileusis (LASIK) on both eyes 10 years earlier. At initial examination, the best corrected visual acuity (BCVA) in her right eye was counting fingers at 2 feet with no correction. Central Goldmann applanation tonometry (GAT) showed an IOP of 7 mm Hg. Peripheral digital tonometry showed the IOPs in her right eye superiorly, nasally, temporally, and inferiorly were 36 mm Hg, 35 mm Hg, 34.5 mm Hg and 36.5 mm Hg, respectively. Slit-lamp examination showed diffuse epithelial and stromal edema and a blood clot 1 mm in height in the anterior chamber. Spectral domain scanning laser ophthalmoscope/ optical coherence tomography (SD-SLO/OCT) images showed a pocket of fluid between the LASIK flap and the underlying stroma. The patient was started on anti-inflammatory agent and IOP lowering agents. After 15 days of treatment, IOP measured with GAT was 10 mm Hg, slit-lamp examination showed that epithelial and stromal edema had disappeared, and OCT showed no fluid between the corneal flap and stroma.

IPO 전후 신용평점과 상장폐지의 관련성에 관한 연구

김문태(Kim, MoonTae),정형기(Jung, Hyungkee) 한국국제회계학회 2014 국제회계연구 Vol.0 No.53

본 연구는 코스닥 기업의 IPO를 전후한 신용평점과 상장폐지의 설명관계를 분석하였다. 2000년부터 2007년까지 코스닥 시장에 기업공개한 572개 기업 중 상장폐지된 190개 기업을 분석하였다. 분석결과, 신용평점은 IPO 직전, IPO, IPO 직후에 점차 하향하는 추세를 보였으며, IPO를 전후한 신용평점과 상장폐지 변수는 매우 강한 음(-)의 설명관계를 보였다. 이는 신용평가기관이 기업의 전반적인 상황을 고려하여 부여한 IPO 신용평점이 낮다면 상장폐지될 수 있는 확률이 높다는 것을 의미한다. 본 연구 결과는 감독과 정책당국에 기업공개 당시의 성과관리, 소유구조, 재무건전성 등 신용평가에 영향을 미칠 수 있는 요인을 규제할 수 있는 회계적 계도와 정책적 방안 마련의 시의적인 논거를 제공하는데 공헌할 수 있을 것으로 본다. 또한 자본시장 참여자들에게 IPO 당시의 신용평점을 통하여 상장폐지에 대한 단서를 미리 인식시키는데 의의가 있을 것이다. This paper examines the relation of credit ratings and delisting firms in KOSDAQ IPO(initial public offerings). The main hypothesis of this study is that the credit score(SCORE) of t-1(before) IPO year, IPO year, and t+1(after) IPO year have the negative relation to the delisting. The main test methods used in this study are correlation analysis, two-sample independent t-test, logistic regression analysis. The test sample consists of 572 IPO firms, selected from the Korea Exchange(KRX) listed companies during 2000~2007. The major findings of the study are that the relationship between SCORE and delisting firms at IPO are negatively significant. In this respect, credit grading plays an important role in informing investors of firm"s financial conditions from IPO(initial public offerings).
