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.

김문태(Kim Moon-tae),정형기(Jung Hyeong-gi) 한국국제회계학회 2016 국제회계연구 Vol.0 No.65

본 연구는 1)타 산업과 구분된 건설산업의 이익조정과 2)개별 건설기업의 규모, 부채수준, 국제회계기준 도입시점 등의 기업특성에 따라 이익조정 정도가 달리 나타나는지를 분석하였다. 이익조정 대용변수는 수정 Jones 모형으로 추정하였으며, 이익조정에 영향을 미칠 수 있는 기업규모, 부채비율, 최대주주지분율, 외국인지분율, 감사인 규모를 통제변수에 포함하였다. 연구대상 표본은 2004년부터 2012년까지 9년 동안 거래소에 상장된 기업-연 횡단표본 3,283개(건설기업은 100개)로 구성되었다. 분석결과, 건설업의 이익 상향조정이 타 산업에 비하여 상대적으로 강하게 나타났다. 또한 건설기업의 기업규모가 크고 부채비율이 높은 기업일수록, 그리고 K-IFRS 의무적용 이후 이익의 상향조정이 강한 결과를 보였다. 이러한 결과는 건설기업이 수주능력평가에서 양호한 점수를 부여받아 경쟁력 우위를 점하기 위하여 이익의 상향조정을 구사한다는 것을 시사한다. The purpose of this study is to examine whether 1)construction firms increase their earnings in comparison with the other industrial firms, and 2)construction firms increase their earnings according to their characteristics such as firm sizes, debt ratios and the mandatory adaption of IFRS. The models include the discretionary accruals(DA) estimated by modified Jones model(Dechow et al., 1995) as the main dependent variables. Also, the test models contain other control variables such as firm size, debt ratio, block-holders, the ownership of foreign investors and big auditors. The test sample consists of 3,283 firm-year data(the samples of construction firms are 100), selected from the KRX listed companies of the fiscal year during 2004-2012(9 years). Results of empirical tests show that earnings management for construction firms is stronger than that of the others, and the firm sizes, debt ratios and the mandatory adaption of IFRS for construction firms have a positive effect on earnings management with statistical significance. These results imply that construction firms boost their earnings to get a good evaluation for capacities for construction orders to survive at the condition of competitive bid.
