In order to investigate the seroprevalence of Salmonella Pullorum in boilers reared in Daejeon area, 509 samples were collected from 10 boiler farms randomly selected from 38. The survey was carried out during 6 months from April to October in 2007. Out of 509 chickens, 35 (6.9%) were seropositive and average titer was $2^{4.8}$. The seroprevalence by district was 5.5% (5/90) in Dong-gu, 4.1 % (4/96) in Seo-gu, 7.9% (24/303) in Yuseong-gu, 10.0% (2/20) in Daedeok-gu.

In order to improve the luminous efficiency in ac PDP(Plasma Display Panel), we have suggested the new structures of sustain electrodes with waffle-type barrier ribs and the discharge current for a given pulse voltage has been decreased by eliminating the electrode area which has nothing to do with visible light emission area compared with conventional structure. As a result, the luminous efficiency was improved about 30% compared with the conventional structure.
