한국원자력연구원은 IAEA에서 권고하고 있는 안전조치기반설계(SBD)에 입각하여 파이로 안전조치 기술을 개발하고 있다. 한국원자력연구원은 파이로 안전조치접근방안 개발을 위한 IAEA 회원국지원프로그램(MSSP)을 수행하였다. IAEA 회원국 지원프로그램을 통하여 기준파이로시설(REPF) 개념을 설계하고, 이 시설에 대한 안전조치시스템을 개발하였다. 최근에 기 준파이로시설은 용량이 증대된 REPF+로 업데이트 되고 있다. 핵물질계량관리시스템 성능평가를 위하여 전산코드 PYMUS 를 개발하였으며, PYMUS는 전용탐지획률 통계평가 방안을 포함하여 업그레이드하고 있다. 파이로 입력물질 계량을 위한 비파괴분석장비로 ASNC가 개발되고 있으며, 파이로 출력물질인 U/TRU 잉곳을 계량하기위한 비파괴분석장비로 HIPAI가 개발되고 있다. 또한 컴프톤 억제 감마선분광기술, LIBS 기술, 균질화 공정의 샘플링 오차에 대한 평가도 진행 중이다. 이러 한 노력들은 국내에서 선진핵주기기술 실현에 크게 기여할 것이다.

Apolipophorin III (apoLp-III) is a well-known hemolymph protein having a functional role in lipid transport and immune response of insects. We cloned full-length cDNA encoding putative apoLp-III from larvae of the coleopteran beetle, Tenebrio molitor (TmapoLp-III), by identification of clones corresponding to the partial sequence of TmapoLp-III, subsequently followed with full length sequencing by a clone-by-clone primer walking method. The complete cDNA consists of 890 nucleotides, including an ORF encoding 196 amino acid residues. Excluding a putative signal peptide of the first 20 amino acid residues, the 176-residue mature apoLp-III has a calculated molecular mass of 19,146 Da. Genomic sequence analysis with respect to its cDNA showed that TmapoLp-III was organized into four exons interrupted by three introns. Several immune-related transcription factor binding sites were discovered in the putative 5’-flanking region. BLAST and phylogenetic analysis reveals that TmapoLp-III has high sequence identity (88%) with Tribolium castaneum apoLp-III but shares little sequence homologies (<26%) with other apoLp-IIIs. Homology modeling of Tm apoLp-III shows a bundle of five amphipathic helices, including a short helix 3’. The ‘helix-short helix-helix’ motif was predicted to be implicated in lipid binding interactions, through reversible conformational changes and accommodating the hydrophobic residues to the exterior for stability. Highest level of TmapoLp-III mRNA was detected at late pupal stages, albeit it is expressed in the larval and adult stages at lower levels. The tissue specific expression of the transcripts showed significantly higher numbers in larval fat body and adult integument. In addition, TmapoLp-III mRNA was found to be highly up-regulated in late stages of L. monocytogenes or E. coli challenge. These results indicate that TmapoLp-III may play an important role in innate immune responses against bacterial pathogens in T. molitor.

Pine wood nematode, Bursaphelenchus xylophilus, is a causative organism to induce pine wilt disease in many varieties of pine trees. Until 2006, Monochamus alternatus had been known as the only insect vector of pine wood nematode in Korea which targeted on Pinus densiflora (Japanese red pine) and P. thunbergii (Japanese black pine). However, pine wilt disease was also reported from Korean pine tree (Pinus koraiensis) in 2006 and we found another insect vector, M. saltuarius, was involved to transmit pine wood nematode. Both Monochamus species were confirmed to transfer pine wood nematode to their hosts but, there is no detail information about other transmitted nematode. Especially Bursaphelenchus mucronatus is common species transmitted by Monochamus species which is morphologically closed to B. xylophilus. Moreover B. mucronatus have two genotypes; one is East Asian type and the other is European type. Both genotypes of B. mucronatus were found in Korea but, the host and vector information related to the genotypes of B. mucronatus was not clear. Monochamus saltuarius was collected from three different geographical locations and nematodes were extracted and identified. For the identification of the juveniles, nematode DNA was extracted and ITS-RFLP analysis was done by PCR and gel electrophoresis. The selected enzymes were Hinf I, Alu I, Msp I, Hae III, Rsa I. Most of Bursaphelenchus species carried by M. saltuarius, which collected from pine wilt disease-free area, was determined as European type of B. mucronatus. We will compare the nematode species and genotypes carried by M. alternatus and M. saltuarius. In addition the rate of nematode carrying insect and the average number of nematode per single insect will be counted and compared.
