후두유두종은 호흡기계에 발생하는 양성종양중 가장 흔한 질환으로 연령에 따라 소아형과 성인형으로 분류하는데 다발성 병변이 흔하고 재발율이 높다고 알려져 있다. 후두유두종의 원인으로는 human papillomavirus의 감염으로 생각되며 잠복 감염으로 인하여 후두유두종이 재발된다고 알려져 있다. Gissman등에 의해 HPV 11이 발견되었음이 보고된 이래 최근까지 HPV 6와 11이 후두유두종의 원인이 된다고 알려져 있다. HPV의 검출에는 Southern blotting이나 in-situ hybridization 방법이 알려져 있는데 저자들은 현재까지의 바이러스 검색방법 중 가장 예민한 방법인 PCR을 이용하여 후두유두종의 HPV DNA를 조사하여 보고자 한다. 저자들은 1989년 10월부터 1900년 12월까지 서울대병원 이비인후과에서 수술을 시행받은 후두유두종 환자 15예를 대상으로 하였으며 이중 소아형은 9예이었고 성인형은 6예였으며 대부분 다발성 병변이었다. HPV 6는 15예중 10예에서 HPV 11은 15예중 6예에서 발견되었으며 두가지 형이 같이 발견된 경우는 1예가 있었다. 소아형의 경우에는 HPV 6와 11이 각각 5예로 비슷한 비율로 검출된 반면 성인형에서는 HPV 6가 주로 검출되었다.

현재 전체 교통사고 건수는 감소하는 추세이지만 보행자 교통사고는 점점 증가하고 있다. 또한 보행자 교통사고 중 고령보행자 교통사고건수 비율이 높은데 이에 따른 원인분석과 예방 대책에 관한 연구가 필요하다. 이에 본 연구는 고령보행자 다발지역을 분석하여 사고 원인을 비교분석 하는 것이다. 다발지역 분석결과 대부분 보행자가 횡단 중 일 때 사고가 발생하였고, 도로형태에서는 교차로, 신호기가 없는 일반도로에서 많이 발생했다. 이에 무단횡단을 방지하는 시설 확대 설치와, 무단횡단의 위험성을 알리는 안전교육의 필요성이 있다고 본다.

This study aims to functionally classify lexical bundles appearing in academic papers on nuclear science and engineering written in English and then analyze the lexical bundles' characteristics compared to those appearing in general academic papers. To this end, the texts of nuclear science and engineering papers were collected and produced as a corpus(c. 1 mil. tokens). Then they were statistically compared through Chi-square tests and standardized residuals with the corpus of general academic papers(c. 750,000 tokens). The results revealed that, compared to general academic papers, the bundles in the stance lexical bundle category were mainly used among the functional lexical bundle in nuclear science and engineering. The use of the lexical bundles lacked much variety. The same type of lexical bundles was 're-used' and 'recycled'. Based on these research results, educational implications for English for Academic Purposes and the further direction of follow-up research were discussed and suggested.

Gastric carcinoid tumor is a neoplasm that arises from enterochromaffine-like (ECL) cells in the gastric fundus. It is a rare disease that comprises less than 2% of all gastric neoplasms; however its incidence has been recently increasing. We experienced one case of gastric carcinoid tumor that was revealed to be multiple polypoid lesions. A 29-year-old female patient visited a hospital three years ago due to syncope. The blood hemoglobin was measured as 6.0 g/dl. Gastroscopy revealed multiple polypoid lesions with bleeding; therefore endoscopic clipping was performed. The polyps were diagnosed as carcinoid tumor via endoscopic biopsy. She was transferred to our hospital because of persistent iron deficiency anemia that was caused by bleeding at the gastric polyps. Gastroscopy revealed more than twenty various-sized polypoid lesions from the mid-body to the antrum. The blood hemoglobin level was 9.0g/dl. Total gastrectomy was performed under the diagnosis of gastric carcinoid tumor with bleeding. All of the gastric polyps were diagnosed as carcinoid tumors, and any metastasis to the regional lymph nodes was not found. Eighteen months after operation, the blood hemoglobin was increased to 12.8g/dl with no evidence of recurrence. Surgical resection should be considered for treating gastric carcinoid tumor with continuous bleeding.

There were 105 patients with multiple rib fracture or flail chest who had underwent surgical rib fixation using judet's strut from Aug. 1989 to Aug. 1995. They were 86 men and 19 women, and the age distribution was from 17 to 77(mean $48\pm12).$ The most common cause of accident was a traffic accident(81%), The mean number of rib fracture was 5.5 and the distribution of patient were flail chest(72, 64.7%), severe displaced rib Fracture(18, 17.1%), traumatic chest wall deformity(10, 95%) and others(5, 4.7%). The operative mortality was 1 patient(0.96%) and the incidence of postoperative complication were 13 patients(12.3%). The duration of perioperative artificial ventilator therapy was $90.5\pm22.6$ hours. Our method allowed shorter duration of an artificial ventiatin and decreased a functional sequelae. We find this technique to be better than previously published methods, since it provides better stabilization and immobilization of he ribs and thus obviates the need for artificial ventilation and prevents post-traumatic chest deformity.

Idiopathic external root resorption is an apparently infrequently occurrence involving single or multiple teeth. Presented is an unusual case of multiple external root resorption associated with craniopharyngioma. Although the cause of this resorption was not determined, several possibilities are discussed. The literature to a systemic etiology for external root resorption is briefly reviewed.
