전방십자인대 손상은 모든 연령 대에서 고위험 운동에 참여하는 인구의 증가로 계속 증가하고 있다. 골-슬개건-골을 이용한 전방십자인대 재건술이 가장 많이 시행되는 수술이다. 지금까지 골-슬개건-골 자가이식물이 가장 이상적인 전방십자인대 재건술의 이식물이라고 하는 주장을 바꿀 만 한 충분한 자료가 아직 없다. 골-슬개건-골 이식물의 생체역학적 특징, 공여부 이환과 적응증을 고찰하고, 이를 이용한 내시경적 전방십자인대 재건술의 수술 수기를 기술하고자 한다. The incidence of anterior cruciate ligament tears is increasing as a result of the increasing participation of individuals of all ages in high-risk sports. Endoscopic anterior cruciate ligament reconstruction using autogenous central third bone-patellar tendon-bone graft is the most commonly used method. With regard to BPTB graft as the go]d standard in ACL reconstruction, there are no data that refute this claim to date. Author reviewed the biomechanical properties, donor site morbidity and selection of the bone-patellar tendon-bone graft and described the surgical technique of endoscopic ACL reconstruction using BPTB autograft.

We present a passively Q-switched monolithic Er:Yb:glass microchip laser developed in our lab. The microchip laser can produce pulses at 1535 nm of the 'eye-safe' wavelengths with the pulse energy of 50 uJ and the pulse width of 4-6 ns. Using the laser we also designed and developed a pulsed Er:Yb:glass microchip laser rangefinder. Expressions for background and signal power, noise, and signal-to-noise ratio are reviewed. A computer simulation was used to optimize laser power, receiver aperture, and preamplifier bandwidth for the efficient system design of the laser rangefinder. Experimental results are presented to compare with the theory.
The Variation of Radiation Transmittance by the cw 1.07 μm Fiber Laser and Water Aerosol Interaction
고해석,전민용,박병서,신완순 한국광학회 2012 Current Optics and Photonics Vol.16 No.3
Among the atmospheric effect of laser propagation, the variations of the radiation transmittance by water aerosol evaporation have quantitatively been investigated. When the aerosol was exposed by a 1.07 μm cw fiber laser, the increased amount of the transmittance variation was a maximum of 19.1% and the volume concentration variation of aerosol was observed as an increasing of laser intensity. Also, significant irregularity of refractive index was not found in the heated area during the continuous laser heating.
