Purpose: To compare modified probing (swing method) to conventional probing for treating congenital nasolacrimal duct obstruction (CNLDO). Methods: From March 1997 to February 2004, we compared the result between two groups of CNLDO patients: one which underwent conventional probing (Group A: 126 eyes of 126 patients) and the other which underwent modified probing (Group B: 98 eyes of 98 patients) with the swing method. Results: In the comparison between the two groups, there were no statistical differences in genders and ages. When we selected patients according to the age group, we found no differences in the primary success rate between Groups A and B (p=0.088 for the patients of aged six to twelve months old, p=0.051 for the patients aged 13 to 18 months old). Compared by the number of probings, patients with no history of probing in each group showed no significant difference in the success rate (p=0.301). On the other hand, the patients in Group B who experienced probing more than once showed a significantly higher success rate than those in Group A (p=0.033). Conclusions: We recommend the swing method as a primary treatment for CNLDO in preference to conventional probing because the swing method shows a higher success rate for patients older than 13 months and also for those with a history of previous probing.

Purpose: To evaluate the usefulness of a new technique for the subciliary approach to the surgical management of anophthalmic, shallow inferior fornices. Methods: Six patients with difficulty retaining an ocular prosthesis, due to anophthalmic, shallow inferior fornices with sufficient conjunctiva, underwent this operation from October 2003 to April 2005. Surgery consisted of the fixation of the conjunctival fornix to the periosteum immediately posterior to the inferior orbital rim through the subciliary approach. This study was prospective. Results: The mean age of the patients was 40.1±14.7 years (range, 21~62 years). Three of six patients were male, and three were female. The mean duration of surgical anophthalmos was 16.8±13.2 years (range, 0.6~40 years), and the mean follow-up period was 9.3±8.4 months (range, 3~25 months). All 6 patients who could not wear prostheses because of shallow fornices could wear ocular prostheses successfully after the operation. An ocular prosthesis could be fitted at a mean duration of 1.83±0.75 weeks (range, 1~3 weeks), postoperatively. Only one patient had mild entropion, but there were no conjunctival contractures or loss of fornices postoperatively. Conclusions: The authors believe that this new technique through the subciliary approach is simple and easy to perform and enables the patient to wear an ocular prosthesis earlier than does forniceal reconstruction through the transconjunctival approach. This technique is very useful in patients with anophthalmic, shallow inferior fornices who have sufficient conjunctiva but loose attachments of the fornix to the underlying tissue, causing shallow fornices.

Enhancement of light trapping in solar cells is becoming increasingly urgent for the development of next generation thin film solar cells. One of the possible candidates for increasing light trapping in thin film solar cells that has emerged recently is the use of scattering from metallic nanostructures. In this study, we have investigated the effects of the geometric parameters of Ag nanorings on the light scattering efficiency by using three dimensional Finite Different Time Domain (FDTD) calculations. We have found that the forward scattering of incident radiation from Ag nanorings strongly depends on the geometric parameters of the nanostructures such as diameter, height, etc. The forward scattering to substrate direction is increased as the outer diameter and height of the nanorings decrease. In particular, for nanorings larger than 200 nm, the inner diameter of Ag nanorings should be optimized to enhance the forward scattering efficiency. Light absorption and scattering efficiency calculations for the various nanoring arrays revealed that the periodicity of nanorings arrays also plays an important role in the absorption and the scattering efficiency enhancement. Light scattering efficiency calculations for nanoring arrays also revealed that enhancement of scattering efficiency could be utilized to enhance the light absorption through the forward scattering mechanism.

Purpose: This large case study evaluated the success rate of revisional surgery and the causes of failed endonasal dacryocystorhinostomy (DCR) with long-term follow-ups. Methods: One hundred nine patients (114 eyes) who underwent revisional surgery for a failed endonasal DCR at the Department of Ophthalmology, Guro Hospital, Korea University between January 1995 and January 2005 were included in this retrospective study. We evaluated the causes of failed endonasal DCR and their success rates of revisional surgeries. Results: The causes of surgical failure were membranous obstruction (83 eyes), granuloma (22 eyes), synechia (11 eyes), common canalicular obstruction (11 eyes), functional block (7 eyes), and canalicular obstruction (1 eye). The revisional surgeries were silicone tube intubation after granuloma removal, synechiolysis and membranectomy using Nd:YAG laser and trephination of canalicular obstruction, and endonasal conjunctivodacryocystorhinostomy (CDCR) for the parts of functional block and the canalicular obstruction. The overall success rates of the revisional surgeries were 83.3% (95/114 eyes). The mean follow-ups period was 18.97 months (range, 9~113 months). Conclusions: This is the first large case study in Korea on revisional surgery with long-term follow-ups, as far as we know. The overall success rates of endonasal DCR after receiving simple revisional surgery were comparable to those of the standard external DCR.

Purpose: To evaluate the usefulness of laser cystectomy for the treatment of patients with dacryocystitis and sump syndrome. Methods: Thirteen patients (13 eyes) diagnosed with acute or chronic dacryocystitis, and nine patients (9 eyes) who developed sump syndrome after dacryocystorhinostomy from 2005 to 2006 underwent laser cystectomy and endonasal dacryocystorhinostomy. Results: Pain and swelling around the orbit improved immediately after the operation in patients with acute dacryocystitis, and all symptoms of sump syndrome disappeared by 1 month postoperatively. Epiphora reduced in all patients. During the follow-up period, functional nasolacrimal duct obstruction occurred in one eye and membranous obstruction developed in two eyes. In these two eyes with membranous obstruction, revisional surgery was performed successfully. No recurrence of dacryocystitis was noticed. Conclusions: Laser cystectomy with endonasal dacryocystorhinostomy is a simple and effective treatment modality for patients with dacryocystitis and sump syndrome that minimizes the risk of recurrence.

Biomedical mobile devices for ubiquitous healthcare consist of biomedical sensors and communication terminal. They have two types of configuration. One is the sensor-network type device using wired or wireless communication with intelligent sensors to acquire biomedical data. The other is the sensor embedded type device, where the data can be acquired directly by itself. There are many examples of sensor network type, such as, fall detection sensor, blood glucose sensor, and ECG sensors networked with commercial PDA phone and commercial phone terminal for ubiquitous healthcare. On the other hand, sensor embedded type mounts blood glucose sensor, accelerometer, and etc. on commercial phone. However, to enable true ubiquitous healthcare, motion sensing is essential, because users go around anywhere and their signals should be measured and monitored, when they are affected by the motion. Therefore, in this paper, two biomedical mobile devices with motion monitoring function were addressed. One is sensor-network type with motion monitoring function, which uses Zigbee communication to measure the ECG, PPG and acceleration. The other is sensor-embedded type with motion monitoring function, which also can measure the data and uses the built-in cellular phone network modem for remote connection. These devices are expected to be useful for ubiquitous healthcare in coming aged society in Korea.

세이렌과 무사

이태수(Lee Tae-Soo) 韓國西洋古典學會 2011 西洋古典學硏究 Vol.43 No.-

이 글은 『오디세이아』에서 오디세우스와 세이렌의 조우가 의미하는 바를 규명하려는 시도다. 그 시도는 두 가지 질문 즉 세이렌의 진정한 정체가 어떤 것인지 그리고 세이렌의 유혹에 대한 오디세우스의 대처 방식이 지닌 함축은 어떤 것인지에 대한 답을 모색하는 과제를 포함한다. 첫 번째 질문에 대하여 이 글은 세이렌이 사실은 『일리아스』적 영웅주의를 노래하는 여신 무사라는 해석을 답으로 제시한다. 두 번째 질문에 대한 답으로는 오디세우스의 대처가 『일리아스』의 영웅 세계를 현실의 세계가 아닌 문학의 세계에 위치시킴으로써 그 세계와 거리를 확보하는 방식으로 영웅주의를 극복하려는 방안이라는 해석을 제시한다. In this paper I inquire into the meaning of the encounter between Odysseus and Siren in Odyssey. The meaning of this encounter can be illuminated by answering the following two questions: the question of what the true identity of Siren is and the question of what the implication of metis applied by Odysseus to resist the seduction of Siren. The answer to the first question consists in revealing Siren as Muse singing about the iliadic heroism. The answer to the second question consists in the interpretation that the aim of Odysseus’ metis is to keep a safe distance from the world of heroism without denying any value to it; this is achieved by relegating the iliadic heroism to the fictive world of literature.
