지속적으로 발생하고 있는 해적 문제에 대해서 해사보안 관련 협약의 시행 이 해적활동을 진압하는 중요한 방법 중의 하나로 여겨진다. 하지만 더 중요한 것은 그러한 협약이 해적방지를 강화하고 선박에 대한 해적활동 대응책을 장려 하며, 그리고 해적을 상대할 수 있는 기타 모든 방법을 도입 및 강화시킬 수 있 는 기회를 제공해야 한다는 것이다. 한편, 나이지리아 해적의 특성은 항만과 주 변 환경, 연안, 공해와 같은 영토적인 요소와 함께 사회적인 요소를 포함하고 있다. 선박 및 항만시설 보안 코드는 해사분야의 이해관계자에게 역할을 분담 함으로써 해적으로 인한 보안 위험요소를 예방하고 극복하는 데 있어서 전 해 역에 걸쳐 적용될 제도를 도입하고 있다. 이 논문은 전 세계의 해적방지를 목적으로 나이지리아 연안에서의 해적을 방지하기 위해 동 코드의 역할을 살펴보 고자 한다. 그리고 이 논문은 동 코드의 효과적이고 광범위한 시행이 해적공격 에 대한 선박의 취약성을 감소시키고 해적위험성 평가를 강화시키며 궁극적으 로 나이지리아 연안에서의 해적발생을 감소시키는 등 해적행위 대응을 위한 능 력개발을 강화시키는지에 대해 고찰해보고자 한다.

The variation of the esterase isozyme, germination rate, chemical composition and digestibility of field bean(G1ycine soja S. and Z.) were estimated. The results are as follows; 1. The banding patterns of the esterase isozyme in field bean were varied wit

BADH1 and BADH2 are two homology genes, encoding betaine aldehyde dehydrogenase in rice. In the present study, we scanned BADHs sequences of 295 rice cultivars, and 10 wild rice accessions to determine the polymorphisms, gene functions and domestication of these two genes. A total of 16 alleles for BADH1 and 10 alleles for BADH2 were detected in transcription region of cultivars and wild species. Association study showed that BADH1 has significant correlation with salt tolerance in rice during germination stage, the SNP P11483(T/A)ishighlycorrelatedwithsalttoleranceindex(STI)(P<10-4). While, BADH2 was only responsible for rice fragrance, of which two BADH2 alleles (P23036, P25390) explain 97% of aroma variation in our germplasm. It indicated that there are no overlapping functions between the two homology genes. In addition, a large LD block was detected in BADH2 region, however, no large LD blocks in a 4-Mb region of BADH1. Only BADH2 region shown significant bias Tajima’s D value from the balance. Extended haplotype homozygosity study revealed fragrant accessions had a large LD block that extended around the mutation site (P23036) of BADH2, while both of the BADH1 alleles (SNP P11483(T/A)) did not show large extended LDblock. All these results suggested that BADH2 was identified as a domesticated gene during rice evolution, while BADH1 was not selected by human beings.

As one of the most important crop, rice is not only a staple food of half world’s population but a wonderful model plant, which has been leading the evolution and functional genomics study. The next-generation sequencing technology are expediting rice genomic study, by providing a simple but powerful way. In this study, we re-sequenced a core collection of 137 rice accessions from all over the world along with 158 Korean breeding varieties. Finally, 6.3G uniquely mapped reads were obtained, and about 10 million SNPs and ~1.2 million InDels were identified with average sequencing depth of 7.5X. These will help us to maximize our germplasm utilization and assists all the deep research in population dynamics and functional studies. Here, we’d like to show the approaches applied to resequencing data mining and on-going activities.

This study was conducted to identify the genetic basis of the domestication-related traits in weedy rice. An RIL population consisting of 80 lines was developed from a cross between the japonica weedy rice, Hapcheonaengmi 3 and the Tongil-type cultivar Mi
