The occurrence of ethyl carbamate was investigated in fermented foods and alcoholic beverages of the Korean total diet study. The concentrations of ethyl carbamate ranged from not detected to 166.5 μg kg−1. Dietary exposure to ethyl carbamate was estimated by the probabilistic method. Estimated intakes of ethyl carbamate from foods and alcoholic beverages were 4.12 ng kg−1 body weight (bw) per day for average consumers and 12.37 ng kg−1 bw/day for 95th percentile high consumers. The major foods contributing to ethyl carbamate exposure were soy sauce (63%), followed by maesilju (plum liqueur, 30%), whisky (5%), and bokbunjaju (black raspberry wine, 2%). On the basis of the benchmark dose lower confidence limit 10% (BMDL10) of 0.3 mg kg−1 bw/day, margins of exposure were 128,000 for mean exposure and 40,000 for 95th percentile exposure. This indicates that the exposure of the Korean general population for ethyl carbamate is of low concern. However, careful vigilance should be continued for high consumers of fermented foods and alcoholic beverages.

축산농가에서 축우의 발정탐지에 실패하는 경우 약 21일 간의 공태가 발생하여 가임 암소의 사료비용, 인공 수정 비용, 송아지 생산 및 착유량 감소 등의 경제적 손실이 따른다. 따라서 축우의 발정을 정확히 탐지하여 수정 적기를 예측하는 것은 축산농가의 소득 및 생산성 향상과 직결되므로 매우 중요하다. 본 논문에서는 효과적인 축우의 발정 탐지를 위한 실시간 체온 모니터링 방법을 제안하고, 실제 축우에 적용해봄으로써 사례분석을 하고자 한다. 본 연구에서 사용한 경구 투여용 센서는 축우 반추위에 안착되어 외부 환경의 간섭 없이 심부 체온을 측정하므로, 실시간으로 지속적인 신뢰도 있는 데이터를 수집할 수 있다. 궁극적으로 제안하는 방법을 통해 농장주는 축우의 발정을 놓치지 않고 탐지할 수 있으며, 발정 시작 시점을 확인해 정확한 수정 적기를 예측할 수 있을 것으로 기대된다.
