  • Burr is a projected part of finished workpiece. It is unavoidable and undesirable by-product of most metal cutting or shearing process. Also, it must be removed to improve the fit of machined parts, safety of workers, and the effectiveness of finishing operation. But deburring process is one of manufacturing processes that have net been successfully automated, so deburring automation is strongly needed. This paper focused on developing a basic algorithm to find edge of workpiece and match two different image data for deburring automation which includes automatic recognition of parts, generation of deburring tool paths and edge/corner finding ability by analyzing the DXF drawing file which contains information of part geometry. As an algorithm for corner finding, SUSAN method was chosen. It makes good performance in finding edge and corner in suitable time. And this paper suggested a simple algorithm to find matching point between CCD image and drawing file.

  • Hydrocele is commonly found clinically and it is associated with patent processes vaginalis. The exact causes of this disease have no been proved up to now however monthly this disease disappears in twelve months after birth but some cases remain. For the treatment we do hydrocelectomy and although the rate of complications were low, sometimes the complications result in reoperations of children. Form the view of oriental medicine, hydrocele is included in susan(水疝) and this treatment originated from naekyung(內經). In this case, we got good results after treating a boy at the age of twenly-five months by bojungikitanggamibang therefor we want to annoume this.

  • Anterior cranial fossa dural arteriovenous fistulae (DAVFs) are very rare and the bleeding rate is very high, especially in the presence of leptomeningeal draining vein and aneurysmal varix formation. A 85-year-old male patient presented with subdural hematoma (SDH). Magnetic resonance image (MRI) and transfemoral carotid angiography (TFCA) disclosed DAVF at the anterior cranial fossa with bilateral arterial feeders and leptomeningeal draining vein with varix formation. The lesion was treated by simple ligation of pial connecting vein using low frontal craniotomy. In comparison with DAVFs of the other sites, the anterior cranial fossa DAVF is difficult to manage by endovascular treatment due to not only the difficulty of transvenous access but the risk of visual impairment when using transarterial route. Surgical ligation of pial connecting vein is feasible and effective treatment.
