시대의 고금 동서를 막론하고 시간적인 중단을 불허하며 연속되는 샌산의 모체인 노동문제는 사회문제의 용아로서 기 해결책 여가는 국가성장을 좌우함에 국가시책중 가장 중요한 부면을 차지하고 있는 것이다. 실용주의의 왕국인 미국에 있어서는 건국 이래 일관하여 사회에 대한 관심이 지대하여 정치인은 물론 각가정 농민에게 이르기까지 보급되어 있는데 이것은 오직 사회적 지식ㅇ이 실제생활에 대하여 실용적인 가치가 있음을 입증하는 것이다. 현 미국의 자본주의는 거의 난숙기의 단계에 다다른 감이 있음에도 불구하고 사회주의가 득세치 못하는 이유의 하난로서 노동자의 힘이 타사회세력과 균등한 지위에 놓여 있다는 점을 들 수 있을 것이다. 특 미국의 노동조합은 자본가한테 부당한 압박을 받지않는 동시에 기 반면 자본가를 압산하지않을 정도로 균형된 힘을 결합시키는 매개체적 역할을 하여 미국식 민주주의 사회로 구성하는 요소가 되었다고 하겠다. 그런데 이것은 결코 오랜 역사를 가진 것이 아니라 20세기의 소산으로서 필연적인 현상이었다 하겠는데 여기에 이르기까지의 사실을 살피는 동시 우리나라의 현실을 고찰코저 한다.

`Purpose: To describe femtosecond laser-assisted corneal biopsy and its use in assessing the causative organism in a case of fungal keratitis that occurred 8 months after penetrating keratoplasty. Case summary: A 27-year-old man who had undergone penetrating keratoplasty 8 months prior showed atypical diffuse corneal haze and erosion. Diagnostic corneal biopsy using a femtosecond laser was performed because of repeated negative test results for an infectious organism and a lack of improvement, despite steroid and empirical antibiotic therapy. A corneal flap 200 μm in depth and 3 mm in diameter was obtained. The biopsy showed pseudohyphae, which led to a diagnosis of Candidal keratitis. No complications occurred during the procedure. Conclusions: Femtosecond laser-assisted corneal biopsy enabled identification of the infectious pathogen. This technique is easy, safe, and rapid, and it yields a biopsy specimen with a uniform depth and precise size. Femtosecond laser-assisted corneal biopsy can be used as an accurate diagnostic method in uncertain cases of corneal ulcers.`

한국인 정상안을 대상으로 서로 다른 수차계로 측정된 안구 수차 값의 비교

염정훈,최석규,김진형,이도형 대한안과학회 2009 대한안과학회지 Vol.50 No.12

Purpose: To compare ocular higher order aberrations measured by two different aberrometers in a sample of normal eyes. Methods: We included 41 normal eyes of Koreans in this study. Ocular aberration data were obtained through three measurements per eye using Zywave and OPD-Scan devices. Spherical equivalent and higher order aberrations calculated in the central 6 mm zone and expressed as root mean square (RMS) values were analyzed. Results: A comparison of measurements between the Zywave and OPD-Scan devices demonstrated no statistically significant differences in the RMS values of total higher order aberration (p=0.11), but significant differences were detected in the RMS values of total spherical aberration, total coma and total trefoil (p<0.01). Conclusions: The two different aberrometers that we tested are suitable for taking repeated measurements and are internally consistent, but not interchangeable. 목적: 한국인 정상안을 대상으로 서로 다른 방식의 수차계로 측정된 안구 수차 값을 비교하고자 한다. 대상과 방법: 한국인 정상안 41안을 대상으로 Zywave와 OPD scan으로 각각 3회 반복하여 안구 수차를 측정하였다. 저위수차는 구면 렌즈대응치를 비교하였고, 고위수차는 6 mm 동공 지름에서 3차에서 5차까지 Zernike 상수 값의 RMS (root mean square) 값을 총고위 수차, 총구면수차, 총코마수차 그리고 총세조각수차로 비교하였다. 결과: 총고위수차의 RMS 값은 Zywave에서 0.409±0.144 μm였고, OPD scan에서 0.436±0.143 μm으로 통계적 차이를 보이지 않았으 며(p=0.11), 총구면수차, 총코마수차 그리고 총세조각수차 RMS 값은 두 수차계간의 차이가 있는 것으로 나타났다(p<0.01). 결론: 두 수차계는 모두 재현성이 높은 검사이지만, 측정된 고위수차는 두 수차계 간의 차이를 보여 임상적에서 서로 혼용하여 사용하는 것은 바람직하지 않을 것으로 생각된다.

Purpose: To investigate the clinical features and compliance of cosmetic contact lens (CL)-related complications compared with soft CL-related complications. Methods: We performed a retrospective chart review of 97 patients (194 eyes) regarded as having CL-related complications at the outpatient clinic. The portion of complications, gender, age, and chief complaints at the initial visit were analyzed, as was compliance to cosmetic and soft CL-related guidelines for use. Results: A total of 97 patients (49 patients with cosmetic CL-related complications and 43 patients with soft CL-related complications) were evaluated. The mean age of the subjects using cosmetic CL was 19.8 years (14-31 years), and all the patients were female. The chief complaints at the initial visit included ocular pain, injection, blurred vision, dryness, itching and foreign body sensation. The main complications included corneal erosion, sterile corneal infiltrate, allergic disease, neovascularization, corneal ulcer and dry eye syndrome. No statistical difference was found regarding chief complaints or complications. The proportion of patients lost to follow-up was 47% in cosmetic CL-related and 20% in soft CL-related complications, a significant difference (<EM>p </EM>= 0.015). Conclusions: Because young females are the most common CL patients and do not always fully comply with the guidelines for use, ophthalmologists need to warn these patients about the risk of serious complications.J Korean Ophthalmol Soc 2014;55(10):1445-1451

To describe the rate of surgical intervention to the intranasal structures for making a sufficient bony ostium in endonasal dacryocystorhinostomy. Methods: Video records of 52 Korean patients (66 eyes) who underwent endonasal dacryocystorhinostomy between January 2010 and December 2010 for primary nasolacrimal duct obstruction were reviewed. To locate the internal common punctum in the lateral nasal wall, a transcanalicular illumination device consisting of disposable vitrectomy light pipe was introduced horizontally through the canaliculus. The relative position of the internal common punctum to the operculum of the middle turbinate was divided into 4 types and analyzed according to the intranasal surgical procedures necessary. Results: Internal common punctum was located posterior-superior to the operculum of the middle turbinate in 37 cases (56%), anterior-superior in 16 cases (24%), posterior-inferior in 11 cases (17%) and anterior-inferior in 2 cases (3%). To expose the bony ostium, partial removal of the operculum of the middle turbinate was required in 63 cases (95%), anterior middle turbinectomy in 43 cases (65%), uncinectomy in 62 cases (94%) and opening of the agger nasi cell in 45 cases (68%). Conclusions: In a majority of patients, partial removal of the middle turbinate, uncinate process and agger nasi cell were necessary to create a sufficient bony ostium. The transcanalicular illumination device is useful to locate the lacrimal sac and can be helpful in understanding the intranasal structures which need to be removed during surgery.

Purpose: To evaluate the changes in higher-order aberrations (HOAs) after implantation of an ICL (implantable contact lens). Methods: Twenty-six eyes that had undergone ICL implantation between February 2008 and October 2009 were included. Ocular higher-order aberrations of all the eyes were measured using the Hartmann-Shack aberrometer (KR9000PW). Examinations were performed preoperatively, as well as one week, one month, and three months after ICL implantation. Changes in ocular total higher-order aberrations, total spherical aberration, coma aberration, trefoil aberration, and S3 and S4 calculated in the central 4-mm zone and expressed as root mean square (RMS) values were analyzed. Results: The mean patient age was 25.4 years, and the mean preoperative spherical equivalent was -6.40 diopters(D). The mean postoperative spherical equivalents were 0.00 ± 0.13D, 0.03 ± 0.21D, -0.013 ± 0.12D at one week, one month, and three months, respectively. There were no statistically significant differences in ocular higher-order aberration RMS, including spherical, coma, or trefoil aberration, at one week, one month, or three months postoperative or between preoperative and postoperative measurements. Conclusions: There is no significant change of ocular higher order aberration in the central 4-mm zone after ICL implantation. J Korean Ophthalmol Soc 2010;51(9):1210-1216

온도센서를 사용하지 않는 MEMS 마이크로히터 온도제어시스템

- In this paper, we present a temperature-controlled system for MEMS electrical resistance heaters without a temperature sensor. To rapidly control the heater temperature, the microheater system developed consists of a power supply, power amplifier, digital Proportional-Integral-Differential (PID) controller, and a quarter bridge circuit with the microheater and three resistors are nominally balanced. The microheaters are calibrated inside a convection oven to obtain the temperature coefficient with a linear or quadratic fit. A voltage amplifier applies the supply voltage proportional to the control signal from the PID controller. Small changes in heater resistance generate a finite voltage across the quarter bridge circuit, which is fed back to the PID controller to compare with the set-point and to generate the control signal. Two MEMS microheaters are used for evaluating the developed control system - a NiCr serpentine microheater for a preconcentrator and a Nickel microheater for Polymerase Chain Reaction (PCR) chip.

Purpose: To report a rare case of thrombocytopenia after intravitreal bevacizumab injection (IVBI) in a patient with macular edema secondary to branch retinal vein occlusion (BRVO). Case summary: A 52-year-old female presented to our clinic with complaints of visual disturbance in her right eye for 2 months. She was receiving hemodialysis therapy 3 times a week for 4 years due to chronic renal failure. Unilateral macular edema secondary to BRVO was observed on fundus examination and was confirmed with optical coherence tomography (OCT). The first IVBI was performed, and an additional injection was given 4 weeks later. Four weeks after the second injection, thrombocytopenia was present. The patient was followed up in our clinic without IVBI for 8 weeks and the platelet count recovered. Thrombocytopenia was reconfirmed after 2 additional monthly injections. After she revisited our clinic without IVBI for 8 weeks, the platelet count recovered without any treatment. Conclusions: When a patient presents with thrombocytopenia after IVBI with macular edema in BRVO, thrombocytopenia due to IVBI should be considered as a possible diagnosis.
