Research Trend of Acoustic Energy Applications

Investigation on acoustic behavior of acoustic porous absorbers to ‎absorb sound energy and transmission loss index

In this study, the acoustic properties of porous absorbents with different porosity levels have been evaluated using different mathematical models. These models use one or more parameters of materials for calculating acoustic characteristics. In all of these models, materials are considered as equivalent fluid and reactionary characteristics have not been taken into account.

Novel Trend in Vaccine Research

and the alarm based on the number and rate of vector species. To monitor vectors that could be coming from overseas, various vectors (mosquitoes, cockroaches, rodents etc) are collected at the National Quarantine Station (19 sites) located at harbors and airports. And in 2009, to effectively cope with climate change, 3 vector surveillance centers were established in Honam, Yeongnam and Jeju are...

The Trend-in-trend Research Design for Causal Inference

Cohort studies can be biased by unmeasured confounding. We propose a hybrid ecologic-epidemiologic design called the trend-in-trend design, which requires a strong time trend in exposure, but is unbiased unless there are unmeasured factors affecting outcome for which there are time trends in prevalence that are correlated with time trends in exposure across strata with different exposure trends...
