The purpose of this research was to examine the relationship between the plasma LDL particle size and blood lipid profile, dietary factors and anthropometric values (body mass index, waist circumference and waist/hip ratio). The subjects were 173 adults aged 23 to 81 years, selected from the Outpatient Clinic and Cardiovascular Department of the Seoul Municipal Hospital. Dietary data were obtained using a 3-day food record and analyzed using Korean and US nutrient databases. The subjects were divided into three groups by LDL particle size:type A (large buoyant LDL, > 25.5 nm, n = 96), type I (Intermediate LDL, 25.2 ≤ - ≤ 25.5 nm, n = 18), and type B (small dense LDL, < 25.2 nm, n = 59) groups. The type B group had higher age, waist circumference, and waist/hip ratio (WHR) than the type A and type I groups. Serum concentration of triglyceride, Apo B, LDL/HDL cholesterol ratio and atherogenic index were significantly higher in the type B group as compared to those in the other two groups. HDL cholesterol level and Apo A-I/Apo B ratio were significantly lower in the type B group than the other two groups. The plasma LDL particle size was highly correlated with triglyceride (r = -0.450), Apo B (r = -0.402) and HDL cholesterol (r = 0.418). However, there was no correlation between plasma LDL particle size and dietary intakes. This study showed that small dense LDL was an important biochemical risk factor that was associated with other risk factors. (Korean J Community Nutrition 9(1) : 58 ~ 65, 2004)

The purpose of this study was to explore urban elementary school students’ natural experiences and examine the relationships among natural experiences, connection to nature, and engagement in science learning. The participants were 272 sixth graders, living in Seoul, Korea. The instrument to survey consists of four parts: perception of nature, companion of natural experience, connection to nature, and engagement in science learning. The results of this study are as follows. First, the average of natural experience near their home and the average of preference for nature in parks and deep forests were the highest. Students often experienced nature with their parents. In addition, the number of positive emotional responses to all natural places was the highest, and the proportion of evocative emotions in deep forests and botanical gardens was higher than in other natural places. Second, natural experience by place, companion of natural experience, and preference for nature by place influence connection to nature positively. Third, connection to nature directly affects engagement in science learning. As the connection to nature is positive, engagement in science learning increases. These results suggest that in order to expand the natural experiences of elementary school students, it is necessary to prepare efficient scientific education methods so that they can experience various natural experiences inside and outside of school.

저자들은 산전 초음파에서 복부 종괴가 발견되어 관찰 도중 복부 팽만과 호흡 부전이 발생하여 방사선요법과 항암요법으로 치료하였던 양측성 선천성 신경모세포종 1례를 문헌 고찰과 함께 보고하는 바이다. 선천성 양측성 신경모세포종의 경우 임상경과를 잘 관찰하고 치료여부를 결정하여야 할 것으로 생각된다. Neuroblastoma is the most common intraabdominal malignant tumor of childhood, with 40% arising from the adrenal gland. Bilateral adrenal involvement from synchronous development or metastatic spread of tumor is rarely seen in children with neuroblastoma. The patient was born with a spontaneous vaginal delivery. Birth weight was 3,200 g. Fetal ultrasonography showed a left adrenal cystic mass. At two weeks of age, she was admitted due to a massive abdominal distension and tachypnea. Percutaneous ultrasonography guided biopsy of the left adrenal mass was performed. The result of the biopsy was neuroblastoma. Vincristine and cyclophosphamide were administerd intravenously and 450 cGy of irradiation was added. Left adrenalectomy was accomplished and postoperative course was uneventful. The patient received cancer chemotherapy with a combination of carboplatin, ifosfamide and VP-16 and is now being followed up for three months. We have experienced a case of congenital bilateral neuroblastoma and report the case with brief review of related literatures.

목 적 : 진행된 신경모세포종 환아의 약물치료 후 수술한 예에서 조직변화를 관찰하여 예후와의 상관관계를 알아보고자 이 연구를 시행하였다. 방 법 : 1991년 1월부터 2000년 6월까지 계명대학교 동산병원 소아과에서 진단된 신경모세포종 환아 중 항암치료 후 종양절제를 시행한 6례를 대상으로 하였다. 진단 당시 침생검소견과 항암치료 후 조직소견에서 신경모세포의 분화정도와 핵 모양 및 간질조직의 기질화 양상과 석회와 유무 등을 비교하여 변형된 Shimada 분류에 따라 분류하였다 결 과 : 항암치료 전과 후에 조직소견의 변화를 관찰하였으며 변형된 Shimada 분류에 따라 2가지 예후군으로 분류하였으며, 좋은 예후군 3례 중 2명은 생존해 있으며, 1명은 추적되지 않고 사망한 것으로 추정하였으며, 나쁜 예후군의 3례는 각각 패혈증과 retinoic acid 복용 중 발생한 출혈성 췌장염으로 사망하였다. 결 론 : 항암치료 전과 후에 조직소견의 변화를 관찰하였으며 Shimada 분류에 따라 비교하고, 치료 후 종양세포의 성숙을 관찰하였으며, 좋은 예후군에서 생존수가 많은 것을 확인할 수 있었다. Purpose : Neuroblastoma is a malignant neoplasm which arises from primitive sympathetic neuroblasts, and occasionally can matured from a malignant neuroblastoma into a benign ganglioneuroma. It has the highest rate of spontaneous regression of any pediatric tumor. We performed a retrospective study of pathologic features after combination therapy in advanced neuroblastoma. Prognostic effects of the individual morphologic feature and prognostic groupings according to modified Shimada classification systems were analyzed. Methods : The treatment results for six patients with neuroblastoma seen at Keimyung University from Jan. 1991 to June 2000 were analyzed. Patients were treated with a combination of chemotherapy, radiation therapy, and surgery, and classified by two major prognostic criteria based on morphological features of neuroblastoma, such as modified Shimada classification and histologic grading. Results : Three cases were classified to a good histologic group; among them, two cases survived, but one case was lost in follow-up. There were three cases classified in a poor histologic group. All of these patients expired due to sepsis and hemorrhagic pancreatitis. Conclusion : Prognostic classification due to pathologic findings had significant value in evaluating the survival rate of neuroblastoma patients.

大邱地域 兒童에서 蟯蟲卵 檢出率의 1973年과 1986年과의 比較

徐蓮瓊,金重洛,鄭東一,崔東翊 慶北大學校 醫科大學 1987 慶北醫大誌 Vol.28 No.1

1986年 2月부터 同年 5月까지 大邱近郊의 都市 및 農村國民學校 學童과 孤兒院生의 蟯蟲 感染率을 Graham氏 scotch-tape檢査法으로 1回 檢査한 다음 Choi等(1973)의 調査 成績과 比較하였다. 이번 調査(1986)에서 被檢兒動 936名 中 蟯蟲卵의 檢出率은 27.8%였고 男兒 26.0%, 女兒 29.6%로서 性別間에 有意的 差를 認定할 수 없었으며 年齡이 增加할수록 높았다. 都市兒童에서의 蟯蟲卵의 檢出率은 1973年 43.4%였던 것이 이번(1986)에는 5.4%로서 顯著하게 減少되었다. 그러나 農村學動과 孤兒院生에서는 그 率에 有意的 減少를 나타내었으나 顯著하지 않았다. From February to May, 1986, urban and rural school children and institution children were examined for the presence of Enterobius vermicularis eggs in the Taegu area. All children were examined once by a modification of the Graham's scotch-tape swab technique, and compared with the results reported by Choi et al. (1973). The detection rate in 936 children was found to be 27.8 per cent. The rate in boys was 26.0 per cent, and the rate in girls 29.6 per cent. There was no significant difference in the rate with regard to sex. But the rate among the urban school children in the present study(1986) was only 5.4 per cent, and markedly decreased as compared with the rate, 43.4 per cent reported by Choi et al. (1973). However, difference in the rate of infestation in both rural school children and institution children was not pronounced between 1973 and 1986.

서연경(Youn-Kyoung Seo),노태길(Tae-Gil Noh),이상조(Sang-Jo Lee) 한국정보과학회 2001 한국정보과학회 학술발표논문집 Vol.28 No.1B

사건, 사고 관련 기사의 요약은 단순히 원문이 무엇을 말하는 가를 지시하는 것보다 가능한 요지를 판독하면서 필요한 정보를 누락시키지 않고 표현할 수 있는 것이 바람직하다. 이를 위하여 본 논문에서는 사건, 사고 관련 기사의 자동 요약문 생성을 위한 중간 개념 표현 방법을 제안한다. 단락 자동 구분을 통한 중요 문장 추출을 거쳐 각 단락의 중심문장을 파악하고, 단락내의 정보들을 의미 파악된 중심 문장에 추가, 병합하여 단락의 내용을 대표하는 Paragraph Representation Structure(PRS)를 생성한다. 이들은 통합과정을 거쳐 하나의 Unified Representation Structure(URS)로 만들어지며, 이것은 중간 개념 표현으로 다국어 자동 요약문 생성을 위한 기반이 될 수 있다. 본 연구에 이용한 코퍼스는 비행기, 선박, 차량, 열차 사고와 화재 폭발 및 사건 관련 신문 기사를 대상으로 한다.
