Multiple fractures are becoming increasing due to traffic and industrial developments. Ipsilateral femur and tibia fractures are caused by high energy trauma and associated with many problems such as hemorrhagic shock, longer morbidity, delayed union of nonunion, knee stiffness etc. Recently the principles of treatment are directed to rigid internal fixation and early mobilization for more satisfactory functional recovery. Since July 1990, we managed 6 patients who had ipsilateral femur and tibia shaft fractures mainly with intramedullary nailing. The results are as follows ; 1. All the 6 cases were accompanied by multiple fractures and/or dislocations. Ipsilateral knee injuries were combined in 2 cases. 2. As for the femur, intramedullary nails were used in all cases. Intramedullary nailing was used for the tibia in 5 cases, and external skeletal fixator in the other one. 3. All the fractures united. Union time of the femoral fractures ranged from 6 to 8 months(mean : 29 weeks ; 6.7 months). Tibia shaft fractures united at from 14 to 32 weeks(mean : 22 weeks ; 5.2 months) postoperatively. 4. 3 Knees recovered full range of motion. But in the other 3 knees, limitations of further flexion to average 100 degrees were noted.

X-線 廻折方法에 依한 Sodium Chloride 單結晶의 構造 硏究
金文執,尹和重,徐日煥 충남대학교 자연과학연구소 1981 忠南科學硏究誌 Vol.8 No.1
The procedure for the crystal structure analysis by means of the X-ray powder diffraction method has been shown using the sodium chloride as a sample. The twelve X-ray diffraction intensity peaks for sodium chloride powder were collected rotating 2θhkl. Bragg angle of X-ray diffractometer from 20 to 160 degrees, in which Cu Kα radiation filtered by nickel had been used. For assigning indices of each reflecting plane, the relationship between lattice parameter and interplanar spacing has been used. This result has shown that sodium chloride is face-centered cubic, space group ?? with unit cell dimension a=5.63Å and z=4. The experimental and theoretical integrated intensities of the reflecting planes are in good agreement with each other.
