  • The transmission capacity has been highlighted as a problem in the power company according to operated heavy loaded of transmission facility. The total transfer capability in the KEPCO power system is determined mainly by the voltage stability limit and many approaches for enhancement of the total transfer capability has been consistently performed. This paper proposes a study on determination of the adequate var sizing of power compensator regarding the transfer capability enhancement in power system. This method was controlled power compensator in substation becasue of the voltage stability. It was simulated power system using EMS peak data.

  • The fracture of facial bone usually accompanies alveolar bone fracture and dislocation or fracture of teeth. Thus, aside from the reduction of fracture, the reconstruction of occlusion through the rehabilitation of lost teeth should be considered. The dislocation of tooth after trauma accompanying alveolar bone fracture needs bone grafting in case of implant treatment. Although autogenous bone graft shows good prognosis, it has the disadvantage of requiring a secondary surgery. This is a case of a mandibular condyle head fracture accompanied by alveolar bone fracture. The condylar head fragment removed during open reduction was grafted to the alveolar bone fracture site, thereby foregoing the need for secondary surgery.
