Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Background and Objectives : Hemorrhage is one of the most common complication after tonsillectomy. Despite of many various efforts, it still remains unsolved problem to many otolaryngologist. Because so many factors are related to postoperative bleeding after tonsillectomy, so we tried to see the postoperative hemorrhage rate in relation to various parameters. Material and Methods : A retrospective study on patients who had underwent tonsillectomy in Wallace Memorial Baptist Hospital for 6 years from January 2002 to December 2007. Parameters such as sex, seasons of year, age distribution, tonsil size, previous tonsillitis history and anesthesia type were considered. Results : Overall hemorrhage rate was 2.6%. Postoperative hemorrhage was common in adult males with incidence of 4.5% and most of them was secondary hemorrhage. In age distribution, the incidence was high in the group of 16~30 year. Bleeding was common in autumn, grade II tonsil and increased when the history of tonsillitis was frequent, and local tonsillectomy was better in terms of bleeding compared with tonsillectomy under general anesthesia. but there was no statistical significance. Conclusion : To reduce the incidence of postoperative hemorrhage, perioperative education and complete bleeding control during operation is important for high risk patients.

Granular cell tumors are relatively uncommon benign laryngeal lesions, especially in children. The granular cell tumor can occurs everywhere in our body. Half of all granular cell tumors occur in the head and neck, with a third of these occuring in the tongue. The larynx is relatively uncommon location, accounting for approximately 7% to 10% of all reported cases. Typically, the most common presenting symptom is hoarseness, with some patients also presenting stridor, hemoptysis, dysphagia. But the tumor may be asymptomatic and be discovered only incidentally during a routine examination. Confirmative diagnosis should be made histopathologically and supported by immunohistochemical staining using S-100. Treatment of a granular cell tumor is complete excision with an attempt to maintain normal structures. We experienced a 14-year-old woman with laryngeal granular cell tumor, which involves the epiglottic lower margin. She was successfully treated with complete excision under laryngomicroscopic dissection. So we report it with a review of literatures.

In order to investigate effect of heated oil on the alkaline and acidphosphatase activity in the rat serum and liver, rats were fed 3and 6 weeks by intubating oils heated for 11 hours(acid value 2.10:HA group) and 24 hours (acid value 4.02: HB group) at 180"C. Thechanges of alkaline phosphotase and acid phosphatase activities inthe serum and liver were observed. Average liver weight of HA andHB group were heavier than control group which were fed the freshcorn oil. In both HA and HB groups, alkaline phosphatase in serumand liver were increased. The activities of alkaline phosphatase inthe HB group was higher than the those of HA group. Changes ofactivity of acid phosphatase in serum of rat fed the heated oil weresimilar to that of alkaline phosphatase. The activities of both enzymeswere decreased in the 6 weeks than 3 weeks.

본 연구에서는 탄소섬유/고인성 EPOXY의 일방향 CFRP적층시험편에 대해 정적 ENF 시험 및 스프릿홉킨손봉법에 의한 동적 ENF시험을 하여 일방향 CFRP 적층판의 모드Ⅱ층간파괴인성치를 측정된 하중응답, 반력봉 반력의 J-적분과 시험편의 변위해석을 통하여 평가하였다 실험결과, 준정적 변위속도 δ = 5 × 10 근방에서 하중 최저점에서부터 하중의 진동이 발생하기 시작함을 알 수 있었으며, 또한 최저 측정점에서 하중점 변위속도의 증가와 더불어 동적 층간파괴 인성치가 증가함을 알 수 있었다. In this paper, an investigation was performed on the dynamic interlaminar fracture toughness of CFRP(carbon fiber reinforced plastics) composite laminates. Composite laminates used in this experimentation are CF/high toughness Epoxy Resin composite laminated plates. In the experiments, Split Hopkinson's Bar(SHPE) test was applied to dynamic and notched flexure test. The mode Ⅱ fracture toughness of each unidirectional CFRP was estimated by the analyzed deflection of the specimen and J-integral with the measured impulsive load and reactions at the supported points. As an experimental results, Loading vibrations are generated when quasi-static displacement velocity, δ becomes 5×10 from the lowest loading point. It is thought that the dynamic fracture toughness of specimens(CF/EPOXY) with the increase of displacement velocity becomes a little greater at a measuring point within the range of measurement.

Drilling tests were carried out austempered ductile cast iron(ADI) to clarify the factors influencing the drilling chracteristics of ADI material. The machinability of material was evaluated using high speed steel drill and cobalt contained drill of 6mm diameter. The spherodal graphite cast iron materials were austenized at 900℃ for in hour and then wear was kept at 375℃ for 2 hours. Austempered ductile cast iron contains a great deal of retained austenite which contributes to an improvement of impact strength. In this paper, machinability of ADI was investigated by drilling experimentation. The results obtained are as follows: a) Flank wear increases logarithmically with the increases of cutting time. b) Relation of flank wear and cutting force can be applied to FZ = 925VB + 820 for the cutting suggested condition. c) Drilling hole number of about 2 times can be reduced more step feed than ordinary feed due to the high hardness of ADI material and hardness increasing ascribed to the martensite of retained austenite.
