  • Broiler chickens were subjected to (i) pre-treatment for 24 h with 1,200 ppm L-ascorbic acid in their drinking water on day 42 (AA), (ii) 60% feed restriction on days 4, 5 and 6 (FR), (iii) combination of AA and FR (AAFR), or (iv) neither treatment (control). On day 43, the birds were crated and transported in an open truck for either 60 min or 120 min. Heterophil/lymphocyte ratios (HLR) were determined prior to ($T_0$) and 20 h following the 60 min ($T_60$) and 120 min ($T_120$) journeys. Prior to transportation, all treatment groups had similar HLR. Following $T_60$, the AAFR chicks had smaller increase in HLR than their control, AA and FR counterparts. The AA, FR and AAFR birds exhibited lower HLR than controls following $T_120$. The means HLR of AA, FR and AAFR did not differ significantly. Irrespective of journey time, AA and AAFR birds had shorter tonic immobility duration than their FR and control counterparts. The tonic immobility duration of all birds increased with journey duration.

  • The ultra slim U-I and W-I primary and pick-up coils for OLEV (On-Line Electric Vehicles) are proposed. With the proposed structures, the amount and the cost of the core are dramatically reduced. Not only air gap but also the lateral displacement are improved. The proposed structures are applied to the OLEV bus and SUV, which achieve 83% efficiency at 17cm air gap with more than 60kW output power, and the construction cost is lower than ￦300M/km. The proposed coil structures are verified with simulations and experiments.

  • Some attempts were made to investigate the gentic characteristics of the brown planthopper(BPH), Nilaparvata lugens Sta${\aa}$l, biotypes. In terms of egg and nymphal periods, egg hatcgability, emergence ratio, and population change of BPH and plant damage of rice cultivars by the infestation of BPH biotypes and their hybrid progenies in field conditions. The egg and nymphal periods of the three of BPH biotypes and their hybrid progenies on Dongjinbyeo with no resistance gene were shorter than on rice cultivars with resistance gene. But the periods of biotype-2(♀) X 2(♂) (E) on Samgangbyeo with Bph-1 gene and biotype-3(♀) X 3(♂)(I) on Mirying 63 with bph-2 gene were as short as on Dongjinbyeo. The egg hatchability and emergence ratio of the three Bph biotypes and their hybrid progenies on Dongjinbyeo were higher than on the other rice cultivars, and those of E on Samgangbyeo and I on Miryang 63 were as high as on Dongjinbyeo. In rice paddy field, biotype-1(♀) X 1(♂)(A)$\sim$I infested on Dongjinbyeo, E onSamgangbyeo, and I on Miryang 63 were increased their population densities remarkably in next generation. Dongjinbyeo infested by A$\sim$I, and Myryang 63 infested by I were hopperburned at 60 days after infestation and had a damage rating of 0.9. But Samgangbyeo infested by E was no hopperburn(damage rating: 7.3) though it showed high BPH population at 60 days after infestation.
