Road runoff, one of non-point source pollutants, contains various heavy metals, most of which flow into discharge waters without being treated. The mechanism of removing the heavy metals in water is similar to that of removing micro-particles. Therefore, it is considered that it is possible to remove a lot of the heavy metals contained in the road runoff by filtering or absorbing them. In this paper, performed has been a basic study on the characteristics of UNFS (Up Flow Non-Point Source Filtering System) using carbide pellet and zeolite pellet as double-layer filtering mediums to treat the road runoff. The removal rate with filtering and absorption time has been shown as follows: 29.0% for Cr; 27.8% for Cd; 25.7% for Fe; 25.4% for Co; 21.2% for Pb; 19.6% for Zn; 18.2% for Al; 17.0% for Mn; 11.3% for Ni; 7.5% for Cu. The overall removal rate according to influx change has been shown to be approximately 30%, and the load of heavy metals flowing out in initial precipitation could be reduced by using carbide as a recycling filtering medium. When the removal as coarse particles settle is added up, it is expected that UNFS will result in a higher removal rate.

갓 김치용 품종 육성을 위하여 외국 도입종 및 국내 수집종 총 24 계통/품종에 대하여 형태적 특성을 조사하였고, 유연 관계 및 주성분 분석을 실시하였다. 주성분 분석에 있어서 총 생체중(제1), 총 건물중(제2), 지상부 생체중(제3), 엽장(제4)으로 80.5%의 전체정보를 해석할 수 있었다. Eigen value가 1이상인 주성분을 토대로 24계통/품종은 7개 그룹으로 분류되었으며, 그룹별 종수는 I군이 1종, II군이 6종, III군이 5종, IV군이 3종, V군이 3종, VI군이 4종, VII군이 2종으로 분류되었다. 또한 12개의 F1 조합능 검정용 교배조합 중 Sanchiohbachirimen takana A × Akaohba takana, Goheung namyang × Sanchiohbachirimen takana A 및 Goheung namyang × Akaohba takana 조합에서 잡종강세가 크게 나타났다. 고수량성 갓 김치 품종육성을 위한 친능성(Parents ability)이 높은 교배친으로 Sanchiohbachirimen takana A와 Akaohba takana가 선발되었다.
