The motivation of this paper is that Stata statistical program users ask if TFDEA code is available in Stata as well as the technology forecasting issues in defense technology planning. It reviews the technology forecasting methodologies and tests the feasibility of non-parametric non-stochastic TFDEA approach using the user written Stata program by comparing with the regression analysis to forecast the weapons system technology. The empirical analysis using the historical air fighter data set of Russia and US between 1944 and 2010 say that TFDEA can be the possible approach compared to the regression analysis to measure the state-of-art technology. This result fairly agrees with the Inman, O.L., T.R. Anderson, and R.R. Harmon(2006) that introduced the TFDEA model.

N/A To determine the significance of inferior ST segment depression during the early stages of acute transmural anterior myocardial infarction, we examined cardiac enzymes, in-hospital complications and indices of ST segment elevation in 51 patients presenting with acute anterior myocardial infarction. The patients were allocated to two electrocardiographic groups. Group I consisted of 19 patients (37%) with a 1 mm or more ST segment depression in at least two of leads II, III, and aVF, Group II consisted of 32 patients without this finding. Compared with group II, patients in group I had a higher peak creatine kinase and lactic dehydrogenase and experienced congestive heart failure, shock, arrhythmias requiring treatment, and death more frequently. Indices of ST segment elevation did not show a significant difference in both groups. The degree of inferior wall ST segment depression correlated weakly with the magnitude of the anterior ST segment elevation(r=0.63, p<0.01). Thus, the inferior ST depression during acute anterior infarction is a reliable marker of more extensive myocardial damage and an adverse hospital course. Such an inferior ST depression might reflect not only reciprocal change, but also ischemia in a remote inferior region.

We observed the gastric varices in l89 variceal patients with liver cirrhosis and in 129 patients with UGI bleeding by endoscopy. Gastric varices was found in 27 cases(14.2%) amoag 189 variceal cases. There was variceal bleeding in 74 cases(57.4%) beieg the toy cause of UGI: bleeding among l29 cases with UGI bleeding and 6(4.7%) had endoscopically proved gastric Variceal bleeding. Cardiac and fundic varices were observed in l8 and 12 cases, respectively end 12 cases of cardiac varices were mainly observed on the lesser curvature side. The incidence of isolated gastric varices being 30 % amoag gastric varices was far less than that of esophagogastric varices. There was no significant relations between the severity of liver cirrhosis and the kinds of varices These results suggest that gastric varices are not infrequent cause of UGI bleeding cases. Therefore all must have attention in gastric intestinal fiberscopic examination in portal hypertensive patients.

In order to screen appropriate preservatives for the suspension containing sucralfate, neusilin and hydrotalcite, the patterns and mechanism of the adsorption and desorption of several preservatives on these antacids were studied. The employed preservatives were parabens(methyl, propyl, butyl), chlorhexidine diacetate and sorbic acid. While none of parabens were adsorbed on three antacids, chlorhexidine diacetate was strongly adsorbed on all the antacids employed, especially on hydrotalcite. Sorbic acid was not adsorbed on nesilin and hydrotalcite, however, 65% of sorbic acid was adsorbed on sucralfate. The adsorption of chlorhexidine diacetate on neusilin and hydrotalcite was partly physical and partly chemical, while its adsorption on sucralfate was almost chemical. Sorbic acid was completely desorbed from sucralfate. In all cases, the adsorption isotherms were fitted well to both Freundlich equation and Langmuir equation. Based on these results, parabens and sorbic acid were the preservatives of choice for the suspension containing sucralfate, neusilin and hydrotalcite.
