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.

Background : In Korea, the rational use of antibiotics are rarely controlled, and their patterns of utilization are not understood. In order to reduce the excessive use and to improve the appropriate use of antibiotics, it is necessary to accurately determine present uses of antibiotics in hospitals. Methods : Analysis of the use of prescription drugs was performed on NFMI(National Federation of Medical Insurance) 1994 medical expense claim data. A stratified sampling by types of hospitals, departments, and diseases was obtained from 1994 August data. Patients with secondary diseases were excluded. In this study, 2,697 adults with URI, 6,397 children with URI, 704 adults with bronchitis, and 1,838 children with bronchitis were included. Results : Most patients were prescribed medication (95.2-99.6%). Of the patients prescribed medication, more than 85% of URI patients and more than 91% of bronchitis patients were prescribed antibiotics. Antibiotics expenses accounted for 14% of total medical expenses in adults and 9% of total medical expenses in children. In adults with URI, antibiotics expenses accounted for 52% of drug expenses. Of the patients prescribed antibiotics, average number of antibiotics used was 1.6-1.7. For patients who are prescribed antibiotics, drug expenses were 62-97% greater than patients not prescribed antibiotics. When children were prescribed antibiotics, the highest price of drugs prescribed were 3.4-fold greater. In addition, the number of drugs prescribed also increased by more than one. Elderly patients, more than 60 years, were prescribed antibiotics less frequently. Children less than 10 years and elderly patients greater than 60 years old were prescribed fewer antibiotics than other patients. And they were prescribed medications for longer days than other patients. Conclusion : This study demonstrated that the average rate of prescribing antibiotics was higher in Korea than other countries. Measures to reduce overuse of antibiotics and to improve the appropriate prescription of antibiotics must be considered for cost effective treatment and overall health of people.
