인도의 간디는 이 세상에는 일곱 가지의 사회악이 있다고 말했다. 원칙이 없는 정치, 노동이 없는 생산, 도덕이 없는 상업, 양심이 없는 쾌락, 특성이 없는 교육, 인간성이 없는 과학, 희생이 없는 종교 예배가 그 내용이다. 마치 지금 우리 사회를 적확하게 진단하고 우리에게 던져준 메시지처럼 보인다. 이제 우리는 우리가 부딪친 몇 가지 주요 현안을 살펴보고, 21세기를 앞두고 이 땅에서 지식인이 나갈 행보를 곰곰히 생각할 시점에 왔다.

Purpose: To compare the clinical effect and complications between patterned laser photocoagulation with short exposure time and conventional laser photocoagulation for neovascularization in branch retinal vein occlusion (BRVO). Methods: A prospective study was conducted on 36 patients (39 eyes) who required laser photocoagulation for neovascularization due to BRVO. The patients were divided into 2 groups, the patterned laser photocoagulation group (laser exposure time 0.02 sec, 3 × 3 array patterned photocoagulation) and conventional laser photocoagulation group (laser exposure time 0.2 sec). Other laser parameters (burn intensity and spot size) were the same. Pain score at the time of treatment was monitored after the laser photocoagulation. In addition, best-corrected visual acuity as well as central macular thickness measurements were performed before the treatment and after 2, 4, 8, and 12 weeks. The regression of neovascularization in fluorescein angiography was monitored during follow-up periods. Results: The patterned laser photocoagulation group had a greater reduction in pain during laser photocoagulation, and a decreased change in central macular thickness after laser photocoagulation than the conventional laser photocoagulation group. In particular, the patterned laser photocoagulation group had a statistically significant difference between the 2 groups at postoperative 8 and 12 weeks. The regression rate of neovascularization between the 2 groups had no statistically significant difference. Conclusions: Patterned laser photocoagulation with a short exposure time decreases pain and postoperative macular edema with no difference in regression of neovascularization. Patterned laser photocoagulation with a short exposure time can be considered as a useful and efficient method for neovascularization in BRVO. J Korean Ophthalmol Soc 2010;51(10):1368-1373

본 논문에서는 가상현실 기술을 기반으로 정비성 모의 시스템에 대한 개발 기술 및 적용 사례에 대해 기술하였다. 정비성 모의를 위해 가상현실 장비를 기반으로 한 몰입형 시뮬레이터가 개발되었으며, 상용 소프트웨어인 DELMIA를 활용한 조립 시뮬레이션이 공대지 유도무기를 대상으로 수행되었다. 개발된 시스템은 설계 단계에서 군수지원 요소 개발에 다양하게 활용이 가능하였으며 효용성을 확인할 수 있었다. This paper describes the development and applications of maintainability simulation system based on virtual reality technology. The immersive type maintainability simulator using virtual reality is developed and assembly simulation using DELMIA software is conducted for an air-to-ground munition as an example. The simulation processes and result validate the feasibility and effectiveness of maintainability simulation system for logistic element development.
