금지은,송원경,손준홍,이성철 대한안과학회 2009 대한안과학회지 Vol.50 No.3

Purpose: To report the anti-inflammatory effect and best-corrected visual acuity (BCVA) response after oral glucosamine (Glucosamine Sulfate 750®, General Nutrition Companies, Inc.) and aspirin (Aspirin protect®, Bayer) therapy in patients with uveitis. Methods: Twenty-seven patients (43 eyes) with uveitis, not easily managed with conventional therapy, were treated with oral glucosamine 750 mg and aspirin 100 mg daily, and underwent BCVA testing and slit-lamp examination of anterior chamber inflammation. Changes in the dose of previously-used oral steroids and immunosuppressants were recorded at baseline, every 2 weeks for the first 2 months, and once every month thereafter. Results: The mean follow-up period was 15.0±3.69 weeks and inflammation started to improve within 4.6 weeks. The change in visual acuity was not statistically significant, but grade of inflammation decreased by as much as 1.02±1.28, significantly (p<0.01) after treatment. In 12 patients (19 eyes, 44.2%) the dosage of systemic steroids and immunosuppressants could be Reduced. 7 patients (10 eyes, 23.3%) experienced aggravation of uveitis and the dosage of glucosamine and aspirin was increased. Conclusions: Concurrent oral administration of glucosamine and aspirin could not completely inhibit the recurrence of inflammation nor control it, but consistent use of these drugs may help to reduce inflammation without serious side effects. A longer prospective control study with larger sample size is required to further evaluation of the efficacy of the medication.

다단계 재구성 가능한 광 네트워크상에서 가상 토폴로지 관리 정책

금지은(Ji-Eun Keum),장린(Lin Zhang),윤찬현(Chan-Hyun Youn) 한국정보과학회 2003 정보과학회논문지 : 정보통신 Vol.30 No.1

본 논문에서는 광 인터넷의 가상 토폴로지 재구성을 효과적으로 관리하는 정책을 제시한다. 기존의 휴리스틱 기법의 근사 문제를 해결하기 위해 트래픽 예측 기반 다단계 재구성 알고리즘을 바탕으로 트래픽 패턴과 망 혼잡 정도의 변화에 따라 적응적인 토폴로지 재구성 기법을 제시한다. 이 알고리즘은 네트워크의 상태를 고려하여 적정 재구성 시기를 결정함으로써 가상망의 관리를 단순화 한다. 시뮬레이션 결과, 제안된 가상망 관리 정책이 물리적인 자원 사용이 제한될 때 기존의 방법에 비해 좋은 성능을 보인다. In this paper, we develop an analytical model to evaluate the virtual topology reconfiguration phase of optical Internet networks. To counter the continual approximation problem brought by traditional heuristic approach, we take the traffic prediction into consideration and propose a new heuristic reconfiguration algorithm called Prediction based Multi-stage Reconfiguration approach. We then use this analytical model to study the different configuration operation policies in response to the changing traffic patterns in the higher layer and the congestion level on the virtual topology. This algorithm persists to decide the optimal instant of reconfiguration easily based on the network state.Simulation results show that our virtual topology management policy significantly outperforms the conventional one, while the required physical resources are limited.

TV 광고를 활용한 중국어교육 방안

나민구,金智恩 한국중국언어문화연구회 2010 한중언어문화연구 Vol.- No.23

We have checked about how to use TV commercials for Chinese education. We focused that TV commercials can be used in various way, and we defined the target is one of students in middle school or high school. As Chinese is getting more remarkable than before, all schools started to choose Chinese as second foreign language. What kind of teaching method is good for students who want to learn Chinese? At the same time, what makes them understand the Chinese culture easily? This answer was TV commercials. For this purpose, in this study, we want to introduce a method that can improve the effectiveness of teaching Chinese language with television commercials. So, in this study, We focus on the effective and practical way of TV commercials as a proper teaching material for the Chinese language class. To this end, we have studied thoroughly how to properly choose and how to use TV commercials in Chinese language class. We believe this study will be utilized in Chinese education someday. And a variety of educational research should be done by a lot of people including ourselves.

이준모,금지은,이성철.Jun Mo Lee. M.D.. Ji Eun Keum. M.D.. Sung Chul Lee. M.D. 대한안과학회 2007 대한안과학회지 Vol.48 No.7

Purpose: To determine whether transpupillary thermotherapy can achieve significant efficacy in maintaining vision without significant adverse effects when used to treat age-related macular degeneration associated with choroidal neovascularization. Methods: Retrospective chart reviews were made for 33 eyes of 32 patients diagnosed with age-related macular degeneration, and who had received transpupillary thermotherapy due to the development of choroidal neovascularization. Transpupillary thermotherapy was performed 1.4 times on average. Results: Three months after the final therapy, 6 eyes (18%) showed improved vision, 11 eyes (34%) showed no change in vision, and 16 eyes (48%) showed worsening of vision. Of the 21 eyes of 21 patients who were available for optical coherence tomography before and after transpupillary thermotherapy, 19 eyes (90.5%) showed reduced macula thickness, and fundus photographs taken during the latest hospital visit revealed 11 eyes showing fibrosis. Conclusions: Although it negatively influences subretinal fluid absorption, transpupillary thermotherapy is effective in stabilizing choroidal neovascularization and improving visual accuracy in a short period of time. Thus, further study is warranted.

A Shared Buffer Constrained Topology Reconfiguration Scheme in Wavelength Routed Networks

윤찬현,금지은,Hye-won Song 한국전자통신연구원 2005 ETRI Journal Vol.27 No.6

The reconfiguration management scheme changes a logical topology in response to changing traffic patterns in the higher layer of a network or the congestion level on the logical topology. In this paper, we formulate a reconfiguration scheme with a shared buffer-constrained cost model based on required quality-of-service (QoS) constraints, reconfiguration penalty cost, and buffer gain cost through traffic aggregation. The proposed scheme maximizes the derived expected reward-cost function as well as guarantees the required flow’s QoS. Simulation results show that our reconfiguration scheme significantly outperforms the conventional one, while the required physical resources are limited.

Purpose: To evaluate the efficacy, safety, and satisfaction of patients who underwent the aspheric micro-monovision protocol for the correction of myopia with presbyopia. Methods: A retrospective, noncomparative study included 40 eyes of 20 consecutive patients with myopia and presbyopia who were treated with LASIK-induced micro-monovision. Monocular and binocular visual outcomes of uncorrected and best-corrected distance, intermediate, and near visual acuity were measured. Depth of focus, spherical aberration, stereopsis and satisfaction were evaluated before surgery and 3 months after surgery. Results: Mean patient age was 48.7 years. Monocular uncorrected distance visual acuity was 0.8 in 94% of dominant eyes, and monocular uncorrected near visual acuity was J3 in 94% in non-dominant eyes. Binocular uncorrected near visual acuity was J2 in 94% and J5 in 100% of dominant and non-dominant patient eyes, respectively. Binocular uncorrected distance visual acuity was 1.0 in 100% of patients, and binocular uncorrected near visual acuity was J2 in 94% of patients. Our results showed a significant improvement in depth of focus and a positive shift in spherical aberration in dominant eyes; however, there were no significant changes in the non-dominant eyes. There was no change in stereopsis or contrast sensitivity at any of the tested spatial frequencies. Satisfactory scores were achieved in all eyes. Conclusions: The aspheric myopic micro-monovision protocol was well-tolerated, stable, and effective for treating patients with presbyopia in myopic astigmatism.
