By the treatment of herb-med, acupunture and Korean(韓方)- medicine, symptoms of nasal polyp has taken a turn for the better, but nasal polyp itself was removed in completely was imppssible. Althogh a surgical operation of western -medicine, the nasal polyp tend to recur. In China, the new treatment that Chinese(漢方)-medicine and western-medicine combined was tried. The trial was effective in decreasing recurrance rate and treatment period. But it's a case of completely removed Nasal polyp through the more vanous Korean(韓方)-medicine, The patient answered in the affinnative of electric acupunture, nasal bloodletting, vaporization, external application against the existing treatment(herb-med, acupunture, moxa). If electric acupunture, nasal bloodletting, vaporization, external application are receiving careful study, they are a help to nasal polyp and opthalmologic, otolaryngologic disease.

본 연구에서는 탑승객의 안전과 국내 환경에 적합한 제동거리 확보를 위해 새로운 개념의 스프링을 사용한 제동장치를 설계하고자 한다. 새로운 제동장치에 사용되는 스프링은 변위에 따라 감쇠 성능 특성을변화시키는 Multi-Rate 변위 감응형 스프링을 최적화하여 적용하였다. 이를 위한 최적화 기법으로는 비선형 최적화 기법인 순차적 2차계획법(Sequential Quadratic Programming, SQP)을 사용하였으며 먼저 Ziprider의 운동을 제동거리와 제동시 발생하는 회전각의 관계로 표현 가능한 수치모델을 개발하였다. 또한 개발된 수치모델은 Matlab을 이용하여 코드화하고 그 결과를 RecurDyn과 비교 분석하였다.

Spontaneous subcutaneous cysts were detected from three dogs, being a 4-year-old male shih tzu, an 11-month-old female britany spaniel and a 9-month-old male mongrel. All the cysts were occurred around the joints (one elbow's and two shoulderes', respectively). After surgical removal, the lesions did not recur for 6 months follow-up. Neither cyst communicated with the joint cavity. Grossly, the subcutaneous ovoid cysts had moderate to abundant mucinous fluid. Histologically, the cyst wall consisted of inner myxomatous and outer immature connective tissue. Some parts of the cyst wall had various stages of myxoid metaplasia of collagen tissue leading to new cyst formation. The true lining cells of the inner cyst wall were not observed in all the cysts. From these results, these cases were diagnosed as subcutaneous ganglion cysts. This is the first report of canine subcutaneous ganglion cysts in Korea.

전동기 구동시스템의 모델링을 위해서는 부하의 부하토크, 관성계수, 마찰계수 등의 정보에 의한 부하 모델링이 반드시 필요하다. 하지만 기본적인 부하모델의 제정수와 단순화된 운동방정식만으로는 기계적 각 부분에서의 발생하는 현상에 대한 해석이 불가능 하다. 본 논문에서는 엘리베이터 도어 구동시스템을 대상으로 기계 해석 분야의 해석 프로그램인 RecurDyn과 전력전자 분야의 시뮬레이션 프로그램인 Simplorer의 Co-Simulation을 통한 부하 모델 및 구동 시스템의 해석 가능성과 해석 범위를 분석하고 실험을 통해 타당성을 검증하고자 한다.

Recent studies on long-term outcome of schizophrenia revealed that schizophrenic symptoms recover in more than 50%, while it remains severe in less than 20% after 20 years or more from the onset. Psychopharmacological studies indicate that 75% of remitted schizophrenics may recur within 2 years after discontinuation of maintenance pharmacotherapy. In addition, family studies revealed that schizophrenic decompensation may occur significantly more frequent in discharged patients with high expressed emotion family than in low expressed emotion family. These findings strongly support a clinical validity of stress-vulnerability concept of schizophrenia which open a new viewpoint to two central problems in schizophrenia treatment, i.e. psychotic relapses and chronification of the fist episode schizophrenia. Moreover, recent psychopathological studies argue that schizophrenic symptoms are manifestations of psychological reaction secondary to a primary cognitive impairment(neurobiological vulnerability), which is originated in neurobiological changes in the brain. Recent approaches to the vulnerability to schizophrenic symptoms or schizophrenic decompensation are reviewed.

Sialolithiasis is the most frequent disease of the salivary glands, causing swelling and/or pain of the affected site. We report a 44-year-old woman who presented with severe pain in the lower left second molar region without swelling. Sialoliths on her left submandibular gland were confirmed by radiographic examinations. After robot-assisted sialoadenectomy, the pain did not recur but remained facial paralysis and unaesthetic scar.

Basal cell adenoma (BCA) is a rare, benign neoplasm that most frequently arises in the parotid gland. We treated a 54-year-old female patient with BCA that had developed in the deep portion of the left parotid gland. The patient presented with gradual facial swelling with no other symptoms. We performed a total parotidectomy to excise the mass, but we preserved the facial nerve. Histopathology revealed a well-encapsulated mass. The tumor was composed of islands of comparatively uniform, small, dark, basaloid epithelial cells in the stroma. Histologic and immunohistochemical studies concluded that the BCA tumors were mostly trabecular. Postoperatively, there was no facial nerve weakness, and the tumor did not recur during the 24-month follow-up period.

This paper is handling about comparative study on dynamic responses of tracked vehicle on soft soil. Two models of tracked vehicle are used in this paper: a single-body model and a multi-body model. Two different methods for dynamic analysis of tracked vehicle are compared: single-body dynamic analysis and multi-body dynamic analysis. Traveling performances of two tracked vehicles are compared.

In the treatment of Nasal Polyps. which are produced with allergic rhinitis, chronic paranasal sinusitis at clinic. Herb-med., acupuncture and some medicine for external application have been used. The symptoms, however, has taken a turn for the better in temporary, the nasal polyps was not removed in completely. So the origin treatment was impossible by the use of herb-med.. acupuncture and medicine. Although a surgical operation (excision) of western-medicine is effective for a specified period of time (about 6 months), the nasal polyps tend to recur. Because of that the second and third operation might be needed, so we cannot consider the operation as the treatment of nasal polyps. The study was observed to investigate the nasal polyps treatment, and to search practical attempt for the clinic application through a literature study on Bisikyuk and Bithch which are similar with nasal polyps. As results, the practical application of external treatment for the nasal polyps treatment in clinic might be more necessary, and internal use of the Herb-med. with the external treatment might be treated as supplementary treatment.

Dynamic model of the Korea standardized rubber-tired AGT light rail vehicle, and boundary conditions between vehicle and infrastructures (running track, guidance rail) were defined to analyze vehicular vibration behaviors occurred at the worst condition. Using the commercialized software RecurDyn, vibration accelerations of car body and bogies were analyzed. and, based on the ISO standard 2631-1, the vibration characteristic test is performed in the test track. As the results, the Korea standardized rubber-tired AGT light rail vehicle satisfied the ISO standard criteria and design requirement.
