전력연구원에서는 ATM WAN 통합망 기반 구축을 통하여 통신회선 임대비용의 절감과 안정적이고 고속의 인터넷 서비스를 수용함으로써 통신망의 경쟁력을 확보하는 것을 목표로 ATM 기반 전력통신망을 설계하였다. 이를 위하여 기존의 패킷 통신망 트래픽 통계 분석결과와 연간 트래픽 증가량 예측치를 기반으로 향후 서비스 수용계획을 고려한 토폴로지와 링크용량을 설계하였으며, 이를 바탕으로 전력통신망에서의 ATM 스위치 기반 네트워크 모델을 확립하였다. 본 논문에서는 ATM 기반 전력통신망의 설계결과를 요약한다.

Background : Among registered fungicides for controlling ginseng disease, the disease occurrence rate from the mixed use of a single ingredient, mancozeb WP, and copper sulfate basic WP was examined, and experiments were conducted to establish safe disease control system. Methods and Results : As for the medicines used for the experiments, besides registered Pyraclostrobin WG as a single ingredient for ginseng disease control, 14 kinds were used for experiments. The fungicide was sprayed 5 times on June 21, July 4, July 16, August 2 and August 24. The examination was conducted 5 days, 10 days, 15 days, and 20 days after the final fungicide treatment. Anthracnose occurrence rate 5 days after the final fungicide treatment was 0.0 - 61.3% which was different depending on fungicides, and in a single treatment, the occurrence rate was less than 1% in 6 fungicides. In the single treatment, the occurrence rate was more than 1%, but 9 kinds of fungicides which had less than 1% occurrence rate in the case of mixed use with mancozeb, and one kind in the case of mixed use with copper sulfate basic 10 days later, the occurrence rate was 0.0 - 100% and there were lots of differences in the disease occurrence rate depending on fungicides. 10 kinds of fungicides showed the disease occurrence rate of more than 10.0% in the case of a single treatment. Among them, 9 fungicides showed the disease occurrence rate of less than 1.0% in the case of mixed use with mancozeb, indicating the effect of lowering disease occurrence rate in the case of mixed use. 15 days later, 9 fungicides showed disease occurrence rate of more than 2%, 1 kind of fungicide had the disease occurrence rate of less than 1%, and the overall disease occurrence rate increased. Among them, 7 kinds of fungicides showed the disease occurrence rate of less than 1% from the mixed use. 20 days later, 12 kinds of fungicides showed the disease occurrence rate of more than 50%, and only 1 kind of fungicide showed the disease occurrence rate of less than 1%. In the case of mixed use with mancozeb, 2 kinds had the disease occurrence rate of less than 10% and 1 kind of fungicide had the disease occurrence rate of less than 1%. Conclusion : For prevention of anthracnose disease of ginsengs during a rainy season, the disease occurrence rate from a single or mixed use was examined, and the examination found that rather than a single use, mixed use decreased the disease occurrence rate. In particular, the mixed use with mancozeb showed low disease occurrence rate and prevented the disease occurrence rate for a long time.
