Purpose: This study demonstrates the effectiveness of the blade plate as an implant for the operative management of proximal tibial fractures. Materials and Methods: Twelve proximal tibial fractures (AO classification, 10 type A and 2 type C) were treated by direct or indirect reduction and condylar blade plate fixation. The condylar blade plate was fixed on the anteromedial surface of the proximal tibia and cancellous bone graft was performed in 4 fractures with severe cortical comminution or bone defect in early cases. At the final follow-up assessment, the patients were evaluated as to subjective symptoms, objective findings, and radiographic findings. Results: All fractures were healed in an average of 13.2 weeks (range, 9.0 to 25.0 weeks). There were 3 major complications of a delayed union, a 6-degree varus malunion, and a reduced range of motion of the knee related with associated multiple fractures of the ipsilateral lower limb, but there were no soft tissue problems, loss of fixation, infection, nonunion, and traumatic arthritis. A few patients complained a prominence of the plate on the anteromedial side of the proximal tibia. Conclusion: Blade plate fixation is a reliable method of stable fixation to obtain good results for proximal tibial fractures by early rehabilitation and good fracture healing, particularly in patients with osteoporosis and cortical comminution.

분말성제제의 안정성에 관한 연구 : 수종제산제중의 Ascorbic acid 의 안정성 관한 연구
신상철,이민화,우종학 한국약제학회 1973 Journal of Pharmaceutical Investigation Vol.3 No.1
There are many reports on the stability of drugs in powders and tablets. The stabilities of ascorbic acid in the antacid preparations, such as calcium carbonate, magnesium carbonate, magnesium trisilicate, magnesium alumino silicate, and dried aluminum hydroxide gel under various humidities were examined. From the result of the experiment, it was assumed that the concentration of ascorbic acid, the amount of water-vapor sorption, and the physical character of the antacid ingredients were the main factors, influencing the degradation of ascorbic acid. The ascorbic acid, mixed with carbonates, such as calcium carbonate, was degradaded rapidly, while the preparation with dried aluminum hydroxide gel was slightly degraded after 10 days. A 2% ascorbic acid in the prepation was rapidly degraded than 10% ascorbic acid in the preparation.

As the volumes increase fast, the management of the Waste Electrical and Electronic Equipment and the waste from ELV become growing problems in Korea. To more efficiently manage the electrical and electronic waste, from January of 2014, Korean government decided to introduce a target system instead of the EPR system which had been adopted in 2003. The target system newly introduced is similar with the EU WEEE Directive. The new scheme set recycling and recovery target for electrical and electronic waste with a minimum rate of 3.9kg per person per annum in 2014, and the rate is going to rise to 6kg per person per annum by 2018. It is expected to be difficult to achieve the targets without putting more efforts. This study was designed to find the policy means to achieve the targets. Also this study suggests to introduce EPR system to improve the recycling of waste from vehicles and end-of-life vehicles.
