Chromosome numbers of 3 species of Korea lampreys(Genus Lampetra) were investigated. Approximately 160 small and mainly acrocentric chromsomes were present in the three species of Korean lampreys. And the diploid chromosome numbers of three species were not significantly different between the species.

The mitotic cycle duration(MCD) and component phase periods of rice(Oryza sativa L.) root meristem cells on the different salt concentrations were investigated by using of tritiated thymidine. The time interval between the maxima of sequential mitotic appearances of marked cells was used as criteria in measuring the MCD of rice. The MCD of rice cultivars 'Seomjinbyeo and Chilseongbyeo' at 0.0%, 0.3%, and 0.6% of salt concentrations appeared the same period as 12hr. The durations of component phase of rice cultivar 'Seomjinbyeo' were the almost same periods at 0.1%, 0.3%, and 0.6% of salt, but in 'Chilseongbyeo' cultivar the G1 and G2 periods were shorter while the S period was longer at 0.3% and 0.6% of salt. Deoxyribonucleic acid(DNA) and protein synthesis were increased while ribonucleic acid(RNA) synthesis was decreased with increasing salt concentrations at Chilseombyeo roots. In Seomjinbyeo roots, DNA and RNA synthesis were decreased while protein synthesis was increased with increasing salt concentrations. These results suggest that DNA, RNA, and protein synthesis may not affect the MCD in rice, but the increase of protein synthesis may be related to the salt tolerance of rice.

일반적으로 잠수함은 핵추진 잠수함과 디젤추진 잠수함으로 구분되는데, 디젤추진 잠수함은 비교적 소형으로 값이 싸고, 상황에 따라서 핵추진 잠수함보다 용이하게 운용할 수 있으므로 그 존재가치가 아직도 크다고 할수 있습니다. 특히 디젤추진 잠수함용으로 폐회로 디젤기관, 스털링기관, 연료전지, 소형 원자로등의 추진방법이 개발되어 금세기안에 실용화되리라 예상되므로 수중지속능력에 대한 디젤추진방식의 제한점은 곧 극복되리라 판단됩니다
