N/A Background : TT virus (TTV), an unenveloped single-stranded DNA virus, has been reported in patients with non A-G posttransfusion hepatitis in Japan. Since it has been distributed globally afterward, it was suggested to be a possible causative agent in a proportion of cases with cryptogenic acute and chronic hepatitis. Therefore, we investigated the prevalence and clinical significance of TTV infection in Korean patients with acute and chronic liver diseases. Methods : TTV DNA was determined by polymerase chain reaction with semi-nested primers in sera of 94 patients with liver diseases: 38 with non-ABC liver diseases, 33 with HBV infection and 23 with HCV infection. Results : TTV DNA was detected in 7.9% of non-ABC group, 6.1% of HBV group and 13.0% of HCV group. The positive rates of TTV DNA among three groups were not different statistically. The prevalences of TTV in acute and chronic liver disease were not different. For our study, six out of eight patients with positive TTV DNA had a past history of transfusion. Conclusion : Although TTV infection exists in Korea, it seems unlikely that the virus is responsible for liver diseases of unknown etiology.(Korean J Med 59:612-617, 2000)

To clarify the proper and safe duration of maturation periods for sawdust-pig manure composts, leaf lettuces were applied with pig manure composts fermented for 15, 30, 45, 60,75 days and 1 year (control) and cultivated in a plastic house with or without additional PE film tunnel. The changes in physiochemical properties of soil and leaf lettuce growth were measured. Shorter duration of maturation periods enhanced the generation of NH<sub>3</sub> gas from the composts and resulted in significant decrease in seed germination, growth and yield of leaf lettuce. Under with and without PE tunnel conditions the concentration of NH<sub>3</sub> from compost over 3.8 and 2.1 mg/100g composts, respectively induced growth reduction. In proportion to the increase of maturation duration saw-dust containing pig manure exhibited decrease in C/N ratio, NH<sub>4</sub><sup>+</sup>-N, NH<sub>4</sub><sup>+</sup>/NO<sub>3</sub><sup>-</sup> ratio but increase in NO<sub>3</sub><sup>-</sup>-N contents. In case of applying pig manure compost without PE film tunnel condition the minimum maturation period of pig manure composts for safe leaf growth was 60 days, while minimum 75 days of maturation was required when applied with PE film tunnel.

서열의 유사성 검색에 잘 알려진 도구로는 BLAST 와 FASTA 가 있으며 이들 알고리즘은 알려지지 않은 유기체를 sequencing 작업을 통하여 얻어진 염기서열과 유전자 데이터베이스를 대상으로 유사성을 검색한다. 이때 서열의 유사성을 검색하기에 앞서 선행 되어야만 하는 sequencing작업은 시간적인 면에서 상당한 비용을 요구한다. 반면 sequencing 작업을 하기 않고도 간단한 실험에 의해 얻을 수 있는 부분적인 서열정보만을 대상으로 데이터베이스에서 검색 할 수 있는 알고리즘으로 RIFLE가 있다. 본 논문에서는 RIFLE 알고리즘을 구현하고 실험데이터를 생성하여 성능에 대한 분석 평가를 하고자 한다. 성능평가 결과 RIFLE 알고리즘은 시간복잡도 O(n<sup>2</sup>)으로 빠른 반면 일부 서열에 있어서 실제 유사도에 비해 정확도가 낮게 평가되는 결과가 산출되었다.
