In this study, a Extradosed PSC railway bridge is analysed for its response under the moving constant train load. Analysis is implemented using Midas/Civil program which is a commercial F.E.M analysis tool and its result is checked against the existing specification standards. It is found that the model bridge used in the study is safe enough in terms of parameters used to check its reliability, but is not the case under the higher speed of the train (over 200km/hr).

This report is consist of a review of 81 patients who substained blunt and penetrating trauma on abdomen during Oct. , 1970 ? July, 1975 on the Surgical Department of Kyung lice Medical College. The non-penetrating injuries of abdomen were 55 cases (67. 9%) and penetrating trauma were 26 cases (32. 1%). The common causes of blunt trauma were traffic accident, fall and violence and of penetraiting trauma were violence, suicide in oder of frequency. In abdominal trauma, the most common organ injuries were small bowel, spleen, kidney, pancreas, liver in order of frequency. Abdominal tapping and radiography were helpful in diagnosis of blunt abdominal trauma. Simple closure were possible in minute injuries to the hollow viscus and liver and splenectomy in spleen injuries and conservative treatment in most kidney injuries. The major complication were infection (16), pulmonary complication (13), ileus (12) and fecal fistular(l). The major causes of death were septicemia (2), head trauma (2), pulmonary complication (2) and total death of patients are 8 of 81 cases (10%).

Objectives : The purpose of this study is to examine the significance of Korean Medical literature on representative symptoms of postpartum deep venous thrombosis (DVT), such as lower extremity edema and pulmonary embolism. Methods : Pattern differentiation, cause, symptoms and treatment related to DVT and pulmonary embolism as written in Korean Medical texts were studied comparatively. Results : In Korean Medical understanding, DVT could be linked to lower extremity edema due to blood stagnation, while pulmonary embolism could be linked to coughing, asthma and nose bleed due to stagnated blood. Conclusions : To prevent relapse and manage its after-effects, Korean Medical treatment for DVT and pulmonary embolism is much in need.

The smoothing method, which is one of the noisy signal processing techniques, is used in order to process the data corrupted with Gaussian White Noise using 5,7 and 9 size window functions. A simple convolution averaging, polynominal curve-fitting and adaptive smoothing methods are used for smoothing. The maximum size of the window function for the simple convolution averaging method is 7, which is about 1/3 of the total sequence, because of the obvious distortion to the original signal. The distortion characteristics of ploynominal curve-fitting method is better than that of the simple convolution averaging method even though the S/N ratio of it is degraded by 3.77 dB for the window size of 5 and 3.63dB for the window size of 9. It is found that the characteristics of filtering of adaptive smoothing method is the best for the 25 sequence data judging from distortion inducement.
