본 연구에서는 협동 로봇의 관절에 들어가는 영구자석 전동기 설계를 위한 다양한 설계 전략을 제안하였다. 로봇 관절용 전동기는 제한된 공간 내에서 큰 토크를 필요로 하며 소음, 진동의 저감이 필수적이다. 이러한 요구 조건을 만족시키기 위하여 토크 밀도를 높일 수 있는 설계 방법, 소음, 진동을 저감 할 수 있는 설계 방법, 그리고 제작성 향상을 위한 설계 방법을 설계에 적용하였다. 또한 로봇용 구동모터의 상용화를 위해 전동기를 구성하는 전기 강판 및 영구자석의 종류, 코어 타입에 따른 전동기의 성능, 가격, 제작 특성을 분석하였다.

N/A Backgroud: Gastric cancer remains the main cause of cancer-related death in Korea. Accurate preoperative staging of gastric cancer is essential to predict prognosis and to plan optimal treatment. Although there are many reports dealing with the diagnostic values of conventional methods, controversies are still present especially in the field of preoperative staging. In this study, we evaluated the accuracy of gastroscopy and upper gastrointestinal series(UGI) for diagnosis of gastric cancer, and determined the usefulness of ultrasonography and computed tomography for preoperative staging. Methods : One hundred twenty-three patients, who underwent operation from Aug. 1991 to Mar. 1995 under the diagnosis of gastric cancer were analyzed. We excluded 15 patients because their postoperative definitive stagings were undetemined. Results : 1) Among 123 patients, the proportion of early gastric cancer was 26.0%(32/123) and that of the advanced gastric cancer was 74.0%(91/123). 2) The sensitivity of endoscopic diagnosis of gastric cancer was 96.7%(119/123), and the accuracy to determine the depth of invasion was 82.9% (102/123). 3) The sensitivity of UGI study for gastric cancer was 89.9%(98/109), and the accuracy to determine the depth of invasion was 61.5%(61/109). 4) The sensitivity of abdominal ultrasonography to detect the tumor was 11.3%(8/71), the accuracy to determine the T stage was 29.2%(28/96), and the sensitivity and specificity to detect lymph node metastasis was 13.6%(8/59), 100%(37/37), respectively. 5) The sensitivity of abdominal CT to detect the tumor was 74.3%(26/35), the accuracy to determine the T stage was 32.5%(13/40), and the sensitivity and specificity to detect lymph node metastasis were 34.5%(9/29), 72.7%(8/11), respectively. 6) The accuracy of preoperative staging was 45.5%(56/123). The 49.6%(62/123) of gastric cancer was downstaged, whereas only 4.1%(5/123) was overstaged. Conclusion: Our results show that high accuracy for diagnosis of gastrie cancer with the gastroscopy and UGI. However preoperative staging with ultrasonography and computed tomograpy was often underestimated, which could be concluded that the usefulness of the radiologic methods was limited.

The term $quot;collagenous colitis$quot; was coined by Lindstrom in 1976 to describe the patient with chronic watery diarrhea who had normal rectal mucosa by proctoscopy but who had a thick subepithelial collagenous deposit on biopsy, and now collagenous colitis is recognized as one of the more common causes of chronic diarrhea of obscure origin. But in this country only a few case has been reported. We have seen a 68-year-old man with chronic watery diarrhea with abdominal pain. Physical examination, laboratory and radiologic studies were no abnormal finding. Colonoscopy disclosed grossly normal mucosa through the entire colon but by histologic examination there are chronic inflammation in the lamina propria and thickened subepithelial collagen layer. Symptoms and pathologic findings of patient improved after treatment with sulfasalazine and prednisolone.

Background/Aims: The aim of this study was to ascertain the effects of two week treatment of omeprazole (O) and clarithromycin (C) with and without metronidazole (M), and one week treatment of omeprazole, clarithromycin and metronidazole, for the eradieation of Helicobacter pylori (H. pylori) in patients with peptic ulcer disease in double-blind, randomly controlled groups. Methods: The H. pylori infection determined in patients whose results were positive in a rapid urease test or in those who exhibited histology in antrum and body, The OC14 group received O 40 mg qd and C 500 mg t.i.d. for 2 weeks; the OCM14 group received O, C, and M 250 mg t.i.d for 2 weeks, and the OCM7 group received O, C, M for 1 week, respectively. H. pylori eradication was assessed 4 weeks after the end of treatment. The H. pylori eradication was determined as all negative for the rapid urease test and histology on both the antrum and body. Results: The eradicaion rates of H. pylori according to OC14. OCM14 and OCM7 were 56.5(13/23), 88.0(22/25), 78.3%(18/23), respectively, The OCM14 regimen was superior to the OC14 in the eradication of H. pylori. All regimens were effective for ulcer healing and symptom relief. Seventeen(25%) cases complained of minor side effects. There were no differences in the ulcer sites, ulcer size, and ulcer stage between eradicated and non-eradicated cases. Conclusions: The OCM14 regimen is effective for the eradication of H. pylori with trivial side effects in peptic ulcer disease. Proper duration of the regimen needs more large acaled study.

DiGeorge syndrome is the developmental anomalies of the third and fourth pharngeal pouches. Recently, damages or abnormal development of the neural crest is suggested as a possible pathogenetic factor, because neural crest cells play a crucial role in development of pharyngeal pouch derivatives, e.g. thymus and parathyroid glands, as well as the aortic arches and conotruncal part of the heat. Most cases have abnormal findings of chromosome 22 and are sporadic, but familial cases have been described. Typical features of DiGeorge syndrome are congenital heart disease, aplasia or hypoplasia of the thymus and parathyroid glands and facial dysmorphism. The main problems and cause of death are severe congestive heart failure due to cardiac anomlies, hypocalcemic complications or immunocompromised conditions. As these results, most cases were expired at infantal period or early childhood. Recently, we have a case of Digeorge syndrome which was associated with complex cardiovascular anomalies(tetralogy of Fallot, atrial septal defect, right aortic arch, left hemitruncus), severe hypocalcemia, aplasia of thymus and facial dysmorphism.
