This study was conducted to suggest a sustainable farming practice forresource recycling in vegetable gardens of North Korea. In North Korea, farmers are allowed to own private vegetable gardens less than $100m^2$. However, usage of fertilizers in private vegetable gardens is very limited due to economic sanctions by UN security council. If North and South Korea initiated the cooperative action in the near future, agricultural sector would be the highest priority cooperation area. Considering the current North Korean situation in agriculture, we would like to suggest a method for producing organic fertilizer manure. For raw materials for producing manure, we selected corn byproduct, which is the most abundant material, and rabbits' feces, which are easily obtained from individual private farms in North Korea. As we cannot get corn byproducts and rabbits' feces from North Korea, we prepared samples of corn byproducts and rabbits; feces from many places in South Korea. After statistical analysis of variance, there was no significant difference in the T-N contents of corn byproducts from Gyeonggi, Gangwon, Chungnam, Chungbuk, Jeollabuk and Gyeongsangnam-dos, which indicates that the fertilizing quality of corn byproducts does not vary significantly in the spatial scale of South. Korea. In this sense, if we use corn samples from Gyeonggi province, they would not be very different from those of North Korean regions. Physicochemical properties of rabbits' feces were different between those eating feed grains and those eating plants only. Hence, we used rabbits' feces of the rabbits from Yeonchun area, which were fed by plants only. Using three different mixing ratios of corn byproducts and rabbits' feces, composting was conducted for 60 days. The mixing ratio of 1:1 produced the manure with % T-N of 1.98% and OM/N ratio of 31.7 after 30 days of composting, which is comparable to the quality of commercial manure.

Group A 로타바이러스 VP6에 특이적으로 반응하는 단크론 항체를 이용하여 로타바이러스 감염이 의심되는 돼지 분변으로부터 로타 바이러스를 검색할 수 있는 효소면역측정법을 개발하였다. 이 효소면역측정법에서는 capture antibody로서 protein A-sepharose를 이용하여 단크론 항체로부터 순수 분리한 immunoglobulin을 사용하였으며 detecting antibody는 토끼 면역혈청으로부터 순수 분리한 immunoglobulin에 biotin을 label하여 사용하였다. 개발된 효소면역측정법의 민감도와 특이성을 전자현미경법 및 형광항체법의 것과 비교하여 보았을 때 서로 유사하였으며 분변재료로부터 로타바이러스를 검색하는데 유용한 것으로 나타났다. 개발된 효소면역측정법은 야외로부터 로타바이러스 검색을 위하여 수집된 많은 양의 분변재료를 실험실내에서 screen하는데 유용하게 사용될 것으로 생각된다.

A 1-year-old female pet rabbit (Lion head, BW: 1.1 kg) was present to the animal hospital for vaccination of viral hemorrhagic disease. This rabbit was adopted in 4-month-old, and contacted with wild cats in outdoors before adoption. We examined feces for Toxoplasma gondii by PCR analysis. We detected the presence of the 497 base pair fragment as a positive result. This is the first detection of T. gondii DNA in a pet rabbit from Korea by PCR analysis.
