Object : To determine whether to use surgical or medical therapy in treatment of infectious intracranial aneurysms, we reviewed two recent cases of infectious intracranial aneurysms and others known previous reports of aforementioned cases. Hence, we attempted to compare the validity and effectiveness of surgical and medical treatment. Method : Recently, we treated two cases of ruptured infectious intracranial aneurysms. In former case, the aneurysm was located distal to the middle cerebral artery in a patient with mild mitral regurgitation of the heart. In latter case, the aneurysm was multiple with varying hemorrhage. The hemorrhage was located bilaterally and a moderate mitral regurgitation and infective endocarditis were accompanied in this patient. Result : Due to the large size of the intracranial hematoma, stable medical condition, and easy resectability, we treated the former patient surgically. And, because of successive hemorrhage by multiple aneurysmal rupture, and the risk of heart failure, we treated the latter patient medically with serial follow-up angiography. Both patients are at present in good health. Conclusion : Because of the variability in associated factors, such as the patient's health, the number of lesions, location, anatomy of the aneurysms and the causative organism, each patient's care must be individualized and tailored to the patient's particular clinical situation.

Objective : The goal of this study is to identify the significant radiologic abnormalities in patients complaining headache and to determine predictive factors for clinically significant radiological abnormalities. Method : The study population was 410 patients having underwent CT or MRI study among 1000 patients complaining headache in outpatient basis between 1996-1999. All of these patients answered self-administered questionaire about their headaches. We reviewed the patient's charts and the questionaires and examined the radiologic study results. Result : Of the 410 patients referred for CT or MRI study, male : female ratio was 1 : 1.97. Twenty-five patients(6.1%) revealed clinically significant organic lesions. Mean age was 46.1 in radiologic abnormal group and 48.4 in normal group. Short symptom duration(p<0.01), motor weakness(p<0.05), vomiting(p<0.05), cranial nerve palsy(p<0.05), and trauma history(p<0.05) were factors indicated higher incidence of radiologic abnormality. But, patients age, and severity of headache were not associated with clinically significant radiologic lesion. The ratio of radiologic abnormality was 0.8% in patients not having any risk factor. Conclusion : The results indicate that radiologic study should be done in headache patients having the risk factors such as short symptom duration, motor weakness, vomiting, cranial nerve palsy, trauma history. For patients without any such a risk factor, the radiologic study doesn't seem mandatory.

Spinal neurenteric cyst results from the persistence of an abnormal communication between endodermal and ne-uroectodermal layer. Embryologically, neurenteric cyst is derived from endoderm that is fused with the developing notochord during the third week of gestation. It is a rare malformation that lead to spinal cord compression. The patient is 19-year-old male presented with chest pain, paresthesia and progressive weakness in his low extremities(grade II/II). Preoperative MR imaging revealed intradural extramedullary cyst with intracystic hemorrhage in T1 and T2 level that is ventrally located and compressed the spinal cord. Involved vertebral bodies were scalloped and fused. The cystic tumor were totally removed through costotransversectomy approach. Postoperatively, motor weakness of the low extremities were improved to the level of grade IV/V. And chest pain and paresthesia were gradually disappeared. Postoperative MR imaging showed the decompression of the thoracic spinal cord. Histologic examination revealed a ciliated columnar epithelial neurenteric cyst. The pre- and postoperative clinical, radiological features of a case of upper thoracic neurenteric cyst is described with review of literature.

AZO (Aluminum-doped Zinc Oxide) is one of the best candidate materials to replace ITO (Indium Tin Oxide) for TCO (Transparent Conductive Oxide) used in flat panel displays, organic light emitting diodes (OLEDs) and organic solar cells (OSCs). In the present study, in order to apply AZO thin film to the transparent electrode of an organic solar cell a low temperature atomic layer deposition (ALD) process was adopted to deposit AZO thin film on flexible Poly-Ethylene-Naphthalate (PEN) substrate. The reactive gases for ALD process were Di-Ethyl-Zinc (DEZ) and Tri-Methyl-Aluminum (TMA) as precursors, and H₂O as an oxidant respectively. The structural, electrical and optical characteristics of the AZO thin film were evaluated with respect to process temperature.
