The object of this study is that develop computer program as being derive simple formula considering complex (material and geometric) nonlinear, and select the most useful truss in efficiency with the analysis Howe truss, Fink truss, Pratt truss and Warren truss. The complex nonlinear behavior is considered in this paper, so is acquired following results. 1. We developed program that could analyze complex nonlinear of plane truss. 2. In view of the results analyzied the numerical analysis example of plane truss, When Howe truss, Fink truss, Pratt truss, and Warren truss are equal to weight and span, and the same load is loaded. Among the trusses of same weight, Warren truss is the most useful in efficiency. And When height of warren truss is changed, the lower height of truss, the more useful in efficiency

A 7-month old, castrated male Shih-tzu dog was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with history of depression, dyspnea, mild scale, tachypnea, exercise intolerance and severe leanness. On physical examination, cardiac arrhythmias was heard and heart worm ELISA test was positive. Microfilaria was found on the direct blood smear. Survey radiographs showed loss of diaphragmatic line and cardiac silhouette, displacement of lung fields and presence of gas filled intestines in the thoracic cavity. Rib fracture and pelvic fracture with callus formation were found incidentally. On the basis of physical examination and radiographic findings, it was diagnosed as traumatic diaphragmatic hernia and heart worm disease. Herniorrhaphy was performed. Postoperatively, it was treated for heart worm disease and scale. There is no evidence of recurrence of diaphragmatic hernia and heart worm disease over 1 year.

위암종환자의 혈청 Sialosy1-Tn 항원 발현에 대한 연구
노명환(Myung Hwan Roh) 대한내과학회 1999 대한내과학회지 Vol.56 No.6
N/A Objective: Sialosyl-Tn (sTn), a mucin-associated carbohydrate antigen, is not expressed by normal mucin- producing cells of the stomach but is expressed in metaplastic, premalignant and malignant gastric tissues. In general, the rate of immunohistochemical expression of sTn in gastric cancer tissue is about 50∼70%, and its prognostic role in gastric cancer is variable. And there is no report in Korea about serum sTn expression of gastric cancer patients , so we have examined the expression of sTn with the serum of gatric cancer patients and examined the possibility of tumor marker and of factors for prognosis. Methods: Serum sTn expression was examined by enzyme linked immuno-sorbent assay (ELISA) in 46 patients with advanced gastric cancer, confirmed at the Dong-A University Hospital, between June, 1997 and June, 1998. We examined the correlations between the expression of serum sTn antigen and patients age, sex, tumor location and size, degree of differentiation, stage, serosal invasion, peritoneal dissemination, hepatic metastasis, lymph node metastasis and Borrmann type. Results: The overall serum sTn expression was higher in cases of advanced gastric cancer than controls (p<0.05). Advanced stages had higher serum sTn expression than lower stages (p=0.0001). And in cases of serosal invasion, peritoneal dissemination and hepatic metastasis, the serum sTn expression was higher than not (p<0.05). Lymph node metastasis, one of determinant factors of stage, had high serum sTn expression but it had not statistical significance (p=0.067), and in cases of sex, tumor location and size, histologic grade and gross findings of tumor (Borrmann type) had not high expression of serum sTn (p>0.05). Conclusion: Higher expression of serum sTn in advanced gastric cancer can be proposed the possibility of the role as a tumor marker. And its higher expressions in many fields of independent prognostic factors also can be proposed the possibility of another independent prognostic factor.
