This paper sets out to explore the patterns of technological change and knowledge spillover in the field of flat panel display (FPD) technology, along with the catching-up behavior of latecomers, through the analysis of US patents and patent citations between 1976 and 2005. Our results show that: (i) the catching-up by FPD technology latecomers began at the(More)
The results of antimicrobial susceptibility testing on 262 strains of Pasteurella multocida and 141 strains of Pasteurella haemolytica isolated from cattle and swine from 1971 to 1974 were analyzed for patterns of resistance to streptomycin, penicillin, tetracycline, and chloramphenicol, using a modified Kirby-Bauer procedure. Resistance was recorded for(More)
A study was undertaken on wild animals to determine the seroprevalence of animal leptospirosis in Korea. Using the serum microagglutination test for 19 serogroups, it was shown that two of 26 rats (Rattus rattus) had antibodies to Leptospira canicola. When data for domestic animals were included, the most prevalent (nearly 50%) serogroup was Leptospira(More)
Arterial PaO2 and cerebrospinal fluid (CSF) lactate, pH, HCO-3, PCO2, and PO2 levels were determined in 52 patients with severe head injury for 1 approximately 5 days. Decreased arterial PaO2 and CSF metabolic acidosis were the most characteristic changes. Sequential analysis of PaO2 and CSF lactate, acid-base unbalance may be used to judge prognosis, to(More)
