  • This study is on the establishment process of Certification Plan of KPP small aircraft development, domestic BASA(Bilateral Aviation Safety Agreement) shadow certification project. For the development of certification plan incorporations process understanding applicable regulations, selection of certification basis, definition of means of compliance and establishment of compliance checklist. On the basis of this process, we develop type certification procedure suitable for domestic small aircraft.

  • A 63 year old male had suffered from hypertension and angina pectoris for 4 years, On physical examination, blood pressure was 150/110 mmHg with medication of antihypertensive drugs. Aortogram showed the stenosis of the left renal artery, the complete occlusion of the right renal artery, and atherosclerotic change of abdominal aorta. Blood urea nitrogen was 25 mg/dl, serum creatinine was 1.2 mg/dl, and renin activity in peripheral blood was 8.7 ng /ml /hour, The stenosis of left renal artery and the complete occlusion of right renal artery should have produced the renovascular hypertension Bilateral aorto-renal bypasses with saphenous grafts were done for treatment of ren-ovascular hypertension Postoperatively, blood pressure was normalized with only small dosage of antihypertensive drugs.

  • This paper describes recently developed techniques for effective filtering of neutron detector signal noise. In this paper, three kinds of noise filters are proposed and their performance is demonstrated for the estimation of reactivity. The tested filters are based on the unilateral kernel filter, unilateral kernel filter with adaptive bandwidth and bilateral filter to show their effectiveness in edge preservation. Filtering performance is compared with conventional low-pass and wavelet filters. The bilateral filter shows a remarkable improvement compared with unilateral kernel and wavelet filters. The effectiveness and simplicity of the unilateral kernel filter with adaptive bandwidth is also demonstrated by applying it to the reactivity measurement performed during reactor start-up physics tests.

  • A teleoperated manipulator system has been developed for remote handling of the spent fuel bundles. A heavy-duty power manipulator with high reduction ratio joints is used for the slave manipulator in the developed system since the handling tasks of the spent fuel bundles need power. Also, the universal type master manipulator, which has force reflecting capability, is used for precise remote manipulation. The power manipulators so frequently occur the control input saturation that the precise control performances are not achieved due to the windup phenomenon. An advanced bilateral control scheme compensating for the saturation is applied to the teleoperated manipulator system. The validity of the developed system is verified by the grid cutting and fuel transportation tasks from the mockup spent fuel bundle.

  • Neurofibromatosis type II is an autosomal dominant, highly penetrant disease whose hallmark is bilateral vestibular schwannoma. Hearing loss is the most symptom in Neurofibromatosis type II. The patient can also present with tinnitus, disequilibrium, and headache. Cranial nerve symptoms, such as facial numbness or weakness, dysphagia, or hoarseness, can also be present. The authors experienced a case of neurofibromatosis type II having huge retropharyngeal mass, retropharyngeal abscess, and bilateral acoustic neuromas. The infection was controled with aggressive antibiotics with drainage. The huge neurilemmoma in retropharyngeal space was removed successfully via transoral approach. The authors report the case with literature review.

  • When driving at night time environment, the whole body of transports does not visible to us. Due to lack of light conditions, there are only two options, which is clearly visible their taillights and break lights. To improve the recognition correctness of vehicle detection, we present an approach to vehicle detection and tracking using finding contour of the object on binary image at night time. Bilateral filtering is used to make more clearly on threshold part. To remove unexpected small noises used morphological opening. In verification stage, paired tail lights are tracked during their existence in the ROI. The accuracy of the test results for vehicle detection is about 93%.

  • A 5-year-old, male mixed breed dog was presented to Gyeongsang National University Animal Hospital for bilateral mandibular open fracture by bite. The dog had loss of the teeth and injury of the oral mucosa. Radio-graphic and blood examinations were conducted. Fracture lines were observed between first premolar and second premolar, but temporomandibular luxation was not observed on radiographs. In serum analysis, elevated levels of CPK and LDH were found. The dog was anesthetized and prepared for aseptic surgery. Acrylic external skeletal fixator with Kirschiner wire was applied. Pin loosening and malalignment of the right fracture line was observed at 7 weeks after surgery. We applied Kirschner-Ehmer fixator and half pins during the second surgical procedure. At 4 weeks after a second surgical procedure, the fixator and pins were removed from mandible. The fractures were healed with no complications.

  • Man-in-the-barrel syndrome (MIBS) is a clinical syndrome of bilateral upper limb weakness with normal lower extremity function. It can be caused by various neurological conditions such as bilateral cerebral hypoperfusion, syringomyelia, motor neuron disease, or cervical myelopathies. We report a patient with MIBS after cervical spinal cord ischemia. It is postulated to be caused by ischemic insults of anterior spinal artery from repeated and prolonged neck extension.

  • Lennox-Gastaut syndrome (LGS) is an electro-clinical syndrome composed of the triad of mental retardation, multiple seizure types, and the characteristic generalized slow spike-wave complexes in the electroencephalogram. In this article, we report on two patients with LGS whose brain magnetic resonance imaging showed dysgenesis of corpus callosum (CC). We discuss the role of CC in the genesis of secondary bilateral synchrony.

  • Accessory navicular is a congenital anomaly appearing in the secondary ossification center on the tuberosity of the navicular that may cause flatfoot. Bipartite medial cuneiform is another rare congenital anomaly occurring as two primary ossification centers in the medial cuneiform. The authors report a rare case of symptomatic bilateral accessory navicular with bipartite medial cuneiform and flatfoot deformity in a 19-year-old man with a review of the literature.
