白米食에 Rivoflavin 添加給食이 白鼠體內 物質代謝에 미치는 影響
吳承浩,李明勳 高麗大學校 倂設 保健大學 保健科學硏究所 1971 保健科學論集 Vol.2 No.1
This study was devised to observe the effect of the rice diet with riboflavin on the metabolic change in rats. The subjects were 36 healthy female albino rats weighing 102∼176 g. They were divided into two groups by diets, the rice diet and the diet enriched with riboflavin, and each group was redivied into three group by feeding terms, 7-day, 15-day and 30-day. After each group was treated with the diet for the corresponding period, the nitrogen, lipid and pyruvic acid in the liver and muscle were determined. The results obtained from this experiment are summarized as follows; 1. In the nitrogen contents in liver of the 15-day feeding group, the diet group enriched with riboflavin shows higher level, and of the 30-day feeding group, less level, compared with the rice diet group. And there was no differences in that in the muscle. 2. In the lipid contents in the liver and muscle of the 15-day feeding group, the diet group enriched with riboflavin is decreased, and of the 30-day feeding group, increased, compared with the rice diet group. 3. In the pyrnivic acid contents in the liver of the diet group enriched with riboflavin in the 7-day feeding group and, in the muscle, in the 30-day feeding group, are remarkably decreased, compared with the rice diet group.

최근 농업 분야에 IT 기술이 결합되면서 농업자동화 시스템에 대해 많은 연구가 진행되고 있으며, 농작물의 생육환경을 자동으로 조절하는 시스템에 대한 연구도 이들 중 하나이다. 농작물의 병충해로 야기되는 피해를 방제하는 작업은 농민들의 미흡한 방제 효과에 대한 염려 때문에 수동방제나 반자동방제에 의해 수행되고 있다. 이러한 방식은 사람이 유해한 약물에 노출되거나 약제 과다 사용으로 인한 낭비 및 환경오염 등의 문제점이 있으므로 개선이 필요하다. 이러한 문제점을 해결하기 위해 농약제조회사에서 제시하고 있는 권장 농약 살포량을 기준으로 경작면적에 따른 방제량을 계산하여 정량 방제를 가능하게 하는 자동화정량방제시스템을 개발하였다. 개발된 자동화정량방제시스템의 효율성을 확인하기 위해서 수동방제 및 반자동방제의 경우와 비교하여 실험하였다. 실험을 통해서 자동화된 시스템이 약제의 과다 사용을 줄일 수 있었으며, 수동방제에 버금가는 방제효과를 얻어 기존의 방제작업을 대체 할 수 있음을 알 수 있었다. Recently, several researches have been studied on agricultural automation system according to convergence of IT technology with agriculture. An automatic control system of the growth environment in crops is one of the these researches. The controls of damages caused by diseases and insects pest in crops are mainly carried out by manual mode or semi-automatic mode because of farmer’s concerns for poor efficiency. But, this situation needs to be improved because it occurs various problems, such as human exposure to toxic pesticides, environmental pollution and waste due to drug overuse. In order to solve these problems, we developed an automatic quantity control system which based on the amount of pesticides for area under cultivation. The amount of pesticides is calculated according to the manufacturer’s instruction for pesticides. To verify the effectiveness of our developed automatic system, we also compared with the systems of manual mode and the semi-automatic mode. The experimental results of a pest control performance of an automatic quantity control system showed that automatic system can reduce overuse of drugs. These results suggested that it can be expected to replace the existing system, with equivalent effectiveness to the manual mode.
