이 글은 지난 5월 29일 본 협회에서 주최한 세계도서의해 기념 강연회에서 “도서관학과 정보과학의 최근연양”이란 주제로 강연한 내용을 간추려 정리한 것이다. 연사 장기택 선생은 1962년에 도미하여 교육심리학 및 Documentation and Information Science를 전공하였다. 1968년에는 Appalachia 교육정보센터의 소장을 역임하였으며 현재는 미국심리학회(APA)의 National Information System for Psychology (NISP)개발 Project의 선임 정보전문가로 활약주이다. 따라서 금번 KIST의 초청으로 일시 귀국하여 약 2개월간 체한하는동안 선생의 바쁜 일정의 틈을 내어 고국의 도서관과 동지들을 위해 강연회를 갖었든 것이다.
Adenomyoma of Ampulla of Vater or the Common Bile Duct- A Report of Three Cases -
장기택,허진석,최성호,최동일,임재훈,오영륜,안긍환 대한병리학회 2005 Journal of Pathology and Translational Medicine Vol.39 No.1
Adenomyoma is a rare non-neoplastic lesion of the biliary tract. Here we report on three cases of adenomyoma; one located in the ampulla of Vater and two located in the common bile duct. Although preoperative endoscopic and radiological evaluations could not determine whether lesions were benign or malignant, intra-operative frozen section histologic examinations aided the differential diagnosis. Microscopic features of a lobular gland architecture with basally located nuclei and the absence of desmoplastic stromal reaction were found to be characteristic in frozen and paraffin sections.

Background : Usually, a malignant intraductal papillary mucinous tumor (IPMT) of the pancreas shows invasive carcinoma. Recently, IPMT with an unusual growth pattern of a fistulous extension was reported. However, little is known about malignant IPMTs with a different growth pattern of invasion and fistulous extension. Methods : Malignant IPMTs were classified into invasive (colloid or tubular type) carcinomas and the fistulous extension type according to their growth patterns. Their clinicopathological characteristics were compared. Results : Among a total of 68 cases of IPMT, there were 16 cases with malignant IPMT; eight, six and two of the colloid, tubular, and fistulous extension types, respectively. The immunohistochemical (IHC) expression of MUC1 was found in seven out of eight colloid and five out of six tubular types, but there was no IHC expression of MUC1 in the fistulous extension type. The IHC expression of MUC2 was noted in one of the eight colloid, one of the six tubular and in both cases with the fistulous extension type. There was no difference in the tumor recurrence rates between the different growth patterns. Conclusions : IPMT with the fistulous extension type has a peculiar extension pattern consisting of multiple fistulous tracts without a mass. Although most of the epithelium in the fistulous tract show moderate to severe dysplasia, only the fistulous extension should be considered to be an unusual growth pattern of malignant IPMT. The clinical significance of this unusual type of IPMT remains to be determined.

Background: The number of patients with disabilities who require general anesthesia for dental treatment is increasing. Methods: We reviewed the cases of 538 patients with disabilities who underwent outpatient general anesthesia for dental treatment at the clinic for the disabled in Seoul national university dental hospital according to the types of disabilities and comprehensive treatments. Results: The patients mean age was 17.4 years and fifty-eight percent of the patients had epilepsy, autism, mental retardation and cerebral palsy. About twenty-five percent of the patients were medically compromised such as brain disease, heart disease and genetic problem. In 142 cases, more than two dentists from the clinical departments systemically co-worked to provide the patients with comprehensive treatment as accurately and quickly as possible under general anesthesia. Conclusions: The number of medically compromised patients was high and the system of comprehensive dental treatment was well run.

To study the antimicrobial effect of fluoride-releasing removable orthodontic appliances, 0 wt%(Group 1), 5 wt%(Group 2) and 10 wt%(Group 3) of $CaF_2$ were added to orthodontic resin. The specimens were then put in media in which S. mutans and Lactobacillus, known cariogenic bacteria, were cultured. Inhibiting zones were measured 24, 48 and 72 hours later. The following conclusions were reached: 1 In the Lactobacillus media, no zone of inhibition was observed regardless of the time passed. 2. In the S. mutans media, zones of inhibition were observed after 48 hours. 3. S. mutans showed greater inhibition in Group 3 compared to Group 2, after 72 hours rather than 48 hours(p<0.01).
