The contents of eleven kinds of biogenic amines were investigated from June to October, 2017 for twenty kinds of cabbage Kimchi, ten kinds of fish sauce, and forty kinds of salted fish purchased from small and medium sized grocery stores in Gyeonggi-Do. In the case of cabbage-kimchi, the amount of each of the BAs in the present study was slightly lower when comparing the detection amounts of each of the ten kinds of BAs and the existing research reports of Joe et al. All five anchovy sauces were less than Maximum Residue limits of European Union(histamine 400 mg/kg) but three of five cases of sandlance sauces were violated Maximum Residue limits of European Union(histamine 400 mg/kg). As a result of analysis of the content ratio of five kinds of BAs reported to be highly toxic to total 11 kinds of analyzed BAs, there was no quantitative correlation between the residual amount of BAs and the residual amount of toxic inducible five kinds of BAs. Estimated daily intake of five kinds of BAs with high possibility of toxicity of kimchi and fermented fish were not more than 6 mg.

This study constructed a wheat-specific primer and a probe using the internal transcribed spacer (ITS). 2 regions of wheat (Triticum aestivum) and real-time PCR conditions were established. The calibration curve showed a slope of -3.356, a correlation coefficient of 0.998, and an amplification efficiency of 98.589%. Experiments were carried out on the rice flour mixed with 50%, 10%, 1%, 0.1%, 0.01%, and 0.001% of wheat. The result showed that it was possible to detect samples mixed with up to 0.01% of wheat. As a result of checking, the wheat detection potential of rice, 34 processed foods, and seven processed foods was ascertained. The real-time PCR method using the wheatspecific primer and probe developed in this study can be used to identify the authenticity of the raw materials, such as the incorrect indication of the raw materials utilized and the unintended mixing of wheat during the manufacturing process.
젓갈류 및 배추김치에서의 바이오제닉 아민류 함량 조사 연구

We determined the contents of 11 biogenic amines in 20 types of cabbage kimchi, 10 types of fish sauce, and 40 types of salted fish purchased from small- and medium-sized grocery stores in Gyeonggi-Do, Republic of Korea, from June to October 2017. The content of each of the biogenic amines in the various types of cabbage kimchi was slightly lower than that in detection amounts of each of the 10 types of biogenic amines and the values reported by Joe et al. The histamine content of all five types of anchovy sauce was lower than the limit set by the European Union (400 mg/ kg), but that of three of the five types of sand lance sauce was higher. Analyzing the ratios of the contents of five highly toxic biogenic amines to those of the 11 biogenic amines yielded no quantitative correlation. The estimated daily intake of the five highly toxic biogenic amines in cabbage-kimchi and fermented fish was ≤ 6 mg.
IMT-Advanced 표준을 지원하는 이중대역 0.13-μm CMOS 송신기 RF Front-End 설계

본 논문에서는 IMT-Advanced 시스템에 적용할 수 있는 0.13-${\mu}m$ CMOS 이중대역 송신단 RF Front-End를 제안한 다. 제안하는 이중대역 송신단 RF Front-End는 3 세대(802.11), 3.5 세대(Mobile WiMAX), 그리고 4 세대(IMT-Advanced) 시스템 주파수 대역을 모두 지원하기 위해서 2300~2700 MHz와 3300~3800 MHz의 이중 주파수 대역을 지원한다. 본 논문에서 제안하는 이중대역 송신단 RF Front-End는 1.2 V의 공급 전원에서 45mA의 전류를 소모한다. 회로의 성능은 레이아웃 후 검증(Post Layout Simulation)을 통해 검증하였으며, 2 GHz 대역에서 +0 dBm의 출력 파워, 3 GHz 대역에서 +1.3 dBm의 출력 파워를 나타낸다. This paper has proposed a dual-band transmitter RF Front-end for IMT-Advanced systems which has been implemented in a 0.13-${\mu}m$ CMOS technology. The proposed dual-band transmitter RF Front-End covers 2300~2700 MHz, 3300~3800 MHz frequency ranges which support 802.11, Mobile WiMAX, and IMT-Advanced system. The proposed dual-band transmitter RF Front-End consumes 45 mA from a 1.2 V supply voltage. The performances of the transmitter RF Front-End are verified through post-layout simulations. The simulation results show a +0 dBm output power at 2 GHz band, and +1.3 dBm output power at 3 GHz band.
