In general, open-loop fiber-optic gyroscopes (FOG) are less stable than closed-loop FOGs but they offer simpler implementation. The typical operation time of line-of-sight (LOS) stabilization systems is a few seconds to one hour. In this paper, a open-loop fiber optic gyroscope (FOG) for LOS applications is designed and implemented. The design goal is aimed at implementing a low cost, compact FOG with low Angle Random Walk (ARW) (< $0.03deg/\sqrt{h}$) and bias instability (< 0.25deg/h). The FOG uses an open-loop all-fiber configuration with 100M PM fiber wound on a small diameter spool. In order to get the design goal, digital signal processing techniques for signal detection, modulation control and compensation are designed and implemented in FPGA.

Herpes zoster oticus which is called Ramsay Hunt syndrome, geniculate ganglion herpes and otic herpes, is characterized by a viral prodrome with otalgia, vesicular eruptions, facial paralysis, hearing disturbance, tinnitus, vertigo and other symtoms. Among cranial nerves, trigeminal and facial nerves are the most commonly affected in patients with herpes zoster oticus, but on rare occasions 8th, 9th, 10th, 11th, 12th cranial nerves and even the upper cervical nerve are influenced as well.. In general, it has poor prognosis compared with Bell's palsy, leaving permanent facial nerve dysfunction. We report a case of Herpes zoster oticus, which was fully recovered by acupuncture and herbal medication within 12 days. We used $FEMA^{11)}$ and House-Brackmann's grading system to assess the degree of paralysis in each part of face.

외이도의 직경 및 길이와 외이도 질환과의 연관성을 알아보고자 73두 성견을 실 험에 이웅하였다. 임상중상, 배양 및 도말 검사를 통하여 외이 질환이 얼는 정상군 57개의 이 관과, 질환이 있는 비정상군 89개의 이관에 직경과 길이를 평가하기 위한 간접적인 방법으로 이관내 조영술을 실시하였다. 비정상군은 정상군에 비하여 윤상연골 및 귓바퀴 연골의 직경 이 더 넓었다. 수직외이도를 구성하는 귓바퀴 연골의 길이는 비정상군4(12.79{\pm} 3.08)이 정상 군(12.79{\pm}5.87 mm)$에서 보다 유의성 있게 길게 나타났다(p<0.001). 심한 외이도 협착증을 보이는 21개의 귀에서는 외이도 질환을 발견할 수 없었으며, 외이도 질환이 심한 귀에 있어 서 그 직경과 길이가 정상군에 비하여 넝고 길게 나타났다(p<0.05). 본 실험의 결과로 보아 외이도관의 협착증과 외이도 질환과는 연관성이 발견되지 않았으나, 환기와 귀내 분비물의 배출을 방해하는 긴 수직외이도를 갖는 귀가 외이도 질환과 밀접한 관계가 있는 것으로 생각 되었다.

The trend of organogenesis in Xenopus presumptive ectoderm was studied by combined dose of activin A and IGF-1(insulin-like growth factor-1). In reference study of Asashima and his colleagues, the inductive patterns of various organs were reported with activin, the potent mesoderm inducing factor. In present study, the inducing pattern was cleared with combined-dose of concentration 1-100 ng/ml activin A and IGF-1. In addition, the result from single treatment of activin A was compared with former study. As a result, eye was differentiated in 5-20% of explants at 10 and 50 ng/ml concentrative combination of activin A. Otic vesicle was appeared in the entire concentrative combination of IGF-1. Pronephric duct was induced 19-38% of explants at the concentration of activin A 100 ng/ml by adding IGF-1. The comparison of single treatment of activin A was showed some difference in dose-dependent inducing pattern.

Urinary tract infection (UTI) is most commonly diagnosed bacterial infection in febrile infants. Renal abscess is a very rare complication of UTI in children. Early diagnosis and treatment with appropriate antibiotics are important because renal scar correlates positively with the time of treatment. Renal ultrasonography and abdominal computerized tomography facilitates an earlier diagnosis and is also useful in establishing percutaneous drainage. Extended broad spectrum antibiotics therapy alone can be effective in most types of renal abscesses in infant, but some antibiotics-resistant cases need surgical drainage or nephrectomy. We report a case of a infant UTI, that progressed to renal abscess despite early antibiotic treatment and was treated with US guided percutaneous needle aspiration.

A 15-month-old, intact male, domestic short hair cat was presented with ataxia, protrusion of the right third eyelid, and anorexia. Clinical signs were firstly noted after ear cleaning at home. Symptoms of the Homer's syndrome were evident. However, postural and proprioceptive reaction deficits were not detected on neurologic examination. Otoscopic examination revealed foreign body in right ear canal. A diagnosis of peripheral vestibular syndrome was made based on results of physical examination including neurologic and otic examination, blood work, and magnetic resonance imaging (MRI). Based on these examinations, the present patient was definitely diagnosed as otitis medial interna induced by foreign body. The vestibular signs were resolved 10 days after removal of cotton tips in right ear canal. This case report indicates that home-care cotton swab can iatrogenically induce otitis media/interna in cats.

A 12-year-old, female, Maltese dog was presented with otic signs, such as pruritus and malordorous discharge. Medical treatment of otitis externa had been carried out for several months at primary animal hospital. Radiography, ultrasonography (US), computed tomography (CT), fine needle aspiration (FNA), and histopathological examination were performed for the diagnosis of ceruminous gland adenocarcinoma. Total ear canal ablation and lateral bulla osteotomy were performed for excision of the tumor. Facial nerve paralysis developed after surgery is getting better through the acupuncture therapy.

The purpose of study is 584 patients who had been treated in the Oriental Medical Hospital at Dong Eui Medical Center during 1 year from February 2001 to January 2002. We proceeded the judgment of Sasang constitution by 'Questiinaire of Sasang Constitution Classification(I)' and 'Questiinaire of Sasang Constitution Classification II(QSCCII)'. The following conclusion were made in comparison with Sasang Constitution and Questiinaire about disease and style of symptoms. 1. The subject of 'increase of the weight of a body(gain weight), cough, nasal discharge(rhinorrhea), stuffed nose, sweatier, more like fat food, more like salty food', has significant differences in sasang constitution classification. The frequency of Taeum group is more than of Soeum group and Soyang group. 2. The subject of 'the complextion is bad, anorexia, indigestion, nervousness, sonitus', has significant differences in sasang constitution classification. The frequency of Soeum group is more than of Taeum group and Soyang group. 3. The subject of 'urodynia, otic discharge', has significant differences in sasang constitution classification. The frequency of Soyang group is more than of Taeum group and Soeum group.

Nebulin is a (Mr 600∼900 kDa) large actin-binding protein specific to skeletal muscle and thought to act as a molecular template that regulates the length of thin filaments. Cardiac muscles of higher vertebrates have been shown earlier to lack nebulin. Recently, full-length nebulin mRNA transcripts have been detected in heart muscle, but at lower levels than in skeletal muscle. Nebulin expression also was detected in the kidney, eye, and otic canal, suggesting that nebulin isoforms may also be expressed in these organs. We have searched for nebulin isoforms in brain of human using PCR and Northern blot. Here, we provide evidence that nebulin mRNA transcripts are expressed in brain. Seven nebulin isoforms (B, C, D, E, F, G and H form) are obtained in human skeletal muscle and four isoforms (B, C, G and H form) in human brain cDNA library. We cloned the 1.3 kb of nebulin fragment from human adult brain library by PCR. The identity of the PCR product was confirmed by sequence analysis. The partial brain nebulin sequence was 99% identical to the skeletal muscle cDNA as determined by Blast alignment. It contains two simple-repeats HR1, HR2 and linker-repeats exon l35∼143 except exon 140. It was different from skeletal muscle B form, which contain HR1 and HR8. These data suggest that nebulin isoform diversity occurs even more extensively than previously known, likely contributing to the distinct thin filament architecture of different striated muscles.
