Korean pig farms face challenges from free trade environment. Many farms have adopted Information System to improve the productivity on the farm. This study applies statistical analysis to verify the productivity gain and its determinants by using information system on the pig farm. Using the farm level weekly data from the PigPlan from 2006 to 2012, we find productivity gain on the farm increa...
In a wind farm, the wakes formed by upstream wind turbines decrease the power outputs of downstream wind turbines by reducing wind speed. This wake interference significantly lowers the power production of a wind farm, especially that of a large-scale wind farm. In this paper, we express wind farm power as a differentiable function of location variables. We then apply a sequential convex progra...

OBJECTIVES Exposure to environments rich in microorganisms such as farms has been shown to protect against the development of childhood asthma and allergies. However, it remains unclear where, and how, farm and other rural children are exposed to microbes. Furthermore, the composition of the microbial flora is poorly characterised. We tested the hypothesis that farm children are exposed indoors...
This study determined whether multilocus sequence types (MLST) of Campylobacter from poultry in 2 farms in Grenada, West Indies, differed by farm, antimicrobial resistance and farm antibiotic use. Farm A used fluoroquinolones in the water and Farm B used tetracyclines. The E-test was used to determine resistance of isolates to seven antibiotics. PCR of the IpxA gene confirmed species and MLST w...
OBJECTIVE Develop and test a farm health and injury prevention educational intervention for high school agriculture students. SETTING Twenty one high schools in Kentucky, Iowa, and Mississippi. METHODS A quasiexperimental crossover design was used to test the effectiveness of two sets of instructional materials designed through participatory action research with agriculture teachers and stu...
