Performance of automobile cooling fan is investigated experimentally by using the large capacity fan tester based on the ASHRAE and AMCA standards. In particular the variation of gap between cooling fan and engine block are considered to obtain the effect of the gap in engine room during design stage. From this study an empirical relation between the fan flow rate and the gap distance was obtained. The final results should be used to develope the predictive technologies of performance and noise for automobile cooling fan with considering the peripheral parts around the engine room such as condenser, radiator, engine block, and support bar.

Lingual thyroid is a rare clinical entity that is due to the failure of the thyroid gland to descend early in the course of embryogenesis. It may be present with symptoms of dysphagia and upper airway obstruction. We report here on the case of a 63-year-old female who was scheduled for an operation for lumbar disc herniation and she could not be intubated. The cause of the airway obstruction was an ectopic thyroid at the base of the tongue, which made visualization of the glottis impossible. Several attempts at endotracheal intubation were unsuccessful. Fortunately, the patient was mask ventilated. We awakened the patient and consulted an otolaryngologist, and she was diagnosed with lingual thyroid. After a week, she was operated on using spinal anesthesia.

We experienced a case of acute cerebral infarction during spinal anesthesia. The patient was a seventy years old male with diagnosis of right femur periprosthetic fracture scheduled for a open reduction & internal fixation under spinal anesthesia. Intraoperatively, he developed a mental confusion and his blood pressure decreased from 115/70 mmHg to 80/45 mmHg. After operation, he appeared to have left hemiparesis and left facial palsy. Angiogram revealed thrombus in superior division of the right middle cerebral artery. He expired 3 months after the surgery despite supportive measures. (Korean J Anesthesiol 2007; 52: 346~9)

N/A We analyzed Radioisotope scan findings of 46 patients of thyroiditis which were proven pathoiogically at K.C.FI. The results were as follows 1) 45 patient.s were female, one was male and average age of patients was 37 years old. 2) The lesion site was predominant in both lobe (67%) Hashimotos thyroiditis showed enlarged thyroid (85%) with cold nodule (20%), diffuse decreased activity (10%), while subacute thyroiditis was presented absent activity (53%), poor visualization (20%) or cold nodule (7%). 4) Radioisotope scan was valuable in evaluationg function of thyroid gland and detection of lesion but there was a limit of pathological nature.

Hypoglossal nerve palsy is a rare complication after general anesthesia with orotracheal intubation. It can present with symptoms of tongue deviation, dysarthria and swallowing difficulties. We report 33-year-old female who was scheduled to undergo surgery for a nasal bone fracture under general anesthesia, using orotracheal intubation. After surgery, she complained right side tongue deviation and, dysarthria, and was diagnosed with right hypoglossal nerve palsy. The cause of the hypoglossal nerve palsy was assumed to be a complication of the orotracheal intubation. Fortunately, the patient fully recovered 2 weeks after surgery.
