Purpose: The goal of the present study was to compare the stability of the 3-piece (TecnisⓇ ZA9003) and single-piece (AcrySofⓇ IQ) aspheric intraocular lenses (IOL) by testing decentration, tilt, anterior chamber depth, and refraction. Methods: The subjects of this study consisted of 101 eyes who had undergone cataract surgeries with a 3-piece aspheric IOL (54 eyes) and with a single-piece aspheric IOL (47 eyes). The decentration, tilt, anterior chamber depth, and refraction were measured on postoperative day 1, 1 month, and 2 months, using an anterior eye segment analysis system (EAS-1000, Nidek, Japan). Results: There was a statistically significant difference in the decentration on the postoperative day 1 (p = 0.04). However, there was no statistically significant difference on postoperative 1 month (p = 0.15) and 2 months (p = 0.13). There was no statistically significant difference in the tilt on postoperative day 1, 1 month, and 2 months. There was no statistically significant difference in the anterior chamber depth on postoperative day 1, 1 month, and 2 months. There was a statistically significant difference in the refraction on postoperative day 1 (p = 0.03). However, there was no statistically significant difference on postoperative 1 month (p = 0.07) and 2 months (p = 0.07). Conclusions: There was no statistically significant difference in the decentration, anterior chamber depth, and refraction between the 3-piece and single-piece aspheric IOL. Therefore, there is no difference between the 3-piece and single-piece aspheric IOL in the capsular bag stability until 2 months postoperatively. J Korean Ophthalmol Soc 2010;51(12):1584-1589

공기스프링을 감쇠기로 사용하는 방진대는 넓은 주파수대역에서 우수한 진동 절연성능을 가짐으로 널리 사용되어 왔다. 하지만 공기스프링은 구조적으로 저강성, 저감쇠의 특성을 가지고 있으므로 외란에 의해 쉽게 가진되어 안정성이 떨어지는 문제가 있다. 이에 공기스프링과 같은 수동소자만을 이용한 수동제어 형식의 보완을 위해 능동 및 반능동 방식의 감쇠기가 제안되고 연구되고 있다. 따라서 본 연구에서는 이러한 수동형 제진대의 능동 및 반능동제어를 위한 동역학적 해석에 관하여 연구하였다. 제진대의 제어시스템 구현을 위하여 6 자유도 제진대의 물리적인 특성에 기초한 동역학적 모델을 정립하고 해석 및 실험을 통해 동역학 모델의 적용가능성을 검증하였다. The anti-vibration tables that use air suspensions as dampers have been widely used due to their high anti-vibration performance in wide frequency band. However, they face a problem of easily accelerating the vibration when triggered by external force because their air suspensions have low rigidity and dampness. In response, there has been a study on active/semi-active dampers that use only the passive components like air suspensions to complement the passive-control format. Thus, we have dynamically analyzed the active/semi-active control of such passive anti-vibration tables. To demonstrate the anti-vibration table's control system, we have also constructed a kinetic model based on the physical characteristics of an anti-vibration table with 6 degrees of freedom and verified its applicability through analysis and experiments.

목적: Klebsiella pneumoniae에 의한 내인성 안내염에서 조기 진단과 치료로 좋은 예후를 보인 1예를 문헌과 함께 보고하고자 한다. 증례요약: Klebsiella pneumoniae에 의한 간농양으로 본원 내과에서 입원 2일째인 52세 여자 환자에서 좌안 통증과 시력감소가 발생한 당일 안과적 검사와 치료가 시작되었다. 좌안 전방에서 검체를 채취하여 시행한 배양검사에서 Klebsiella pneumoniae가 동정되었다. 안과증상 발생 2일전부터 내과에서 전신적 항생제 주사로 치료 중이었으며, 안과증상이 발생한 당일 유리체 내 항생제 주사 및 항생제 점안액으로 치료하였다. 10일 후, 21일 후 유리체 내 항생제 주사를 2회 추가 시행한 결과 염증이 치유되었으며 교정시력 0.8로 시력도 보존되었다. 결론: 간농양 환자에서 발생한 Klebsiella Pneumoniae 내인성 안내염 환자의 경우 안과의사와 내과의사의 협력 하에 조기 진단과 치료가 시력 예후에 중요한 영향을 미칠 것으로 생각된다. Purpose: To Report and review a case Prognosis of Klebsiella Pneumoniae endogenous endophthalmitis by early diagnosis and treatment. Case summary: A-52-year-old female hospitalized in internal medicine department for 2 days with liver abscess by Klebsiella pneumoniae was referred to us in consultation on the day of patient first complained her ocular pain and visual loss in her left eye. Ophthalmologic evaluation and antibiotic treatment were performed. Culture revealed Klebsiella pneumoniae from anterior chamber of the left eye. Systemic antibiotics, intravitreous antibiotics injection and antibiotic eye drops were performed. Additional intravitreous antibiotic injection were performed twice on day 10 and day 21, and the inflammation was cured and corrected visual acuity conserved 0.8. Conclusions: Early diagnosis and treatment by cooperation of physicians (internist) and ophthalmologists of Klebsiella pneumoniae endogenous endophthalmitis in liver abcess patients have an important effect on the prognosis of visual acuity.
