Corn (Zea mays. L) is one of the potential export crops of Myanmar. It is crucial to develop locally adapted high yielding hybrids to dramatically increase production. International Corn Foundation/Kyungpook National University (ICF/KNU) and Department of Agricultural Research (DAR) have developed a collaborative research to develop super hybrids. Under this program, 11 preliminary test cross trials including 538 crosses were tested in AungBan and NyaungMon (mid altitude) and Tatkone (lowland) Myanmar, and ICF Agric Center in Cambodia, 2008 rainy season. Test cross seeds were produced in Cambodia and Myanmar during 2007 winter season. Germplasms from Nepal, Myanmar, IITA, and CIMMYT were used. Simple estimates of commercial value score (1= best, 9= poorest) with yield potential, good agronomic traits and disease tolerance were rated. The analysis of variance for each trial showed highly significant among test crosses and better performance than local check hybrids. VN3 x SSA showed the highly tolerance to Northern Corn Leaf Blight in sticky corn trial. The outstanding performance was recognized in Nepal materials crossed with IITA materials. It is point out that overseas aids collaborative breeding and training of young staff are effective parts of Myanmar hybrid corn R&D program.

The control of earliness has an agronomic importance since it reduces growing and harvesting time. Earliness is controlled by multiple genes in multiple pathways and influenced by the environment. In Arabidopsis thaliana, many earliness related genes were identified. Among them, Arabidopsis Frigida (FRI) gene confers late flowering phenotype, which is reversed to earliness by vernalization. Blast search using FRI against soybean EST database at TIGR identified Isoflavone reductase-like gene (TC217830). Fifty seven SNPs were identified in a total of 4,242 bp lengths in genomic region of Isoflavone reductase-like from 62 soybean genotypes (31 early maturity group and 31 late maturity group). From the obtained sequences, we identified 6 haplotypes of Isoflavone reductase-like gene. Among them, three haplotypes showed a significant association with maturity, suggesting that Isoflavone reductase-like gene is tightly linked to flowering time or actual gene it-self. Thus, to delimit a putative genomic region for maturity and flowering time, SSR markers near Isoflavone reductase-like gene were designed and analyzed for their genetic diversity, assuming that highly selected regions might posses lower genetic diversity. Through these experiments, the region related to maturity and flowering was delimited to nearby ac_satc_4 in scaffold 16.

As a method to reduce collision accidents of ships at sea, this paper suggests an expert system for collision avoidance and navigation (hereafter "ESCAN"). The ESCAN is designed and developed by using the theory and technology of expert system and based on the information provided by AIS and RADAR/ARPA system. In this paper the ESCAN is composed of four(4) components; Facts/Data Base in charge of preserving data from navigational equipment, Knowledge Base storing production rules of the ESCAN, Inference Engine deciding which rules are satisfied by facts or objects, User System Interface for communication between users and ESCAN. The ESCAN has the function of real--time analysis and judgment of various encountering situations between own ship and targets, and is to provide navigators with appropriate plans of collision avoidance and additional advice and recommendation This paper, as a basic study, is to introduce the basic design and function of ESCAN.

전세계 주요 원자력선진국들의 사용후핵연료 처리에 대한 기술 및 정책현황을 알아보고 향후 우리나라의 연구방향을 제시해 보았다. 재처리 정책을 가진 소위 핵연료주기 국가들은 최근 선진핵 연료주기기술에 기초한 새로운 사용후핵 연료 관리정책을 발표하였다. 그 정책은 사용후핵연료 내에 함유된 우라늄 또는 초우란 원소들을 재순환하고 고독성의 방사성 물질 및 장반감기를 가진 물질들을 소멸하거나 단반감기 원소로 변환하는데 초점을 맞추고 있다. 이러한 정책은 원자력의 자원 활용성을 높일 뿐만 아니라, 영구 처분할 고준위폐기물의 양을 감소시켜 궁극적으로 원자력의 지속가능성을 높여 준다. PUREX 방법에 기초한 습식재처리를 우선순위로 선택한 대부분의 국가들은 이 습식방법이 건식방법에 비해 실용화에 앞서 있음을 그 선택 의 근거로 든다. 그러나 습식방법은 건식에 비해 핵확산저항성 측면에서 더욱 민감하다. 왜냐하면 이 습식방법은 약간의 공정수정에 의해 순수 플루토늄을 회수 할 수 있기 때문이다. 반면에 아직까지 실용화 단계까지는 도달해 있지 않지만 고온 용융염을 사용하는 Pyroprocess와 같은 건식처리 방법은 순수한 플루토늄을 회수 할 수 없어서 핵비확산성 측면에서 유리하며, 제4세대 원자로로 고려되는 고속로의 핵연료주기 등에도 여러 가지 이점을 가지고 있다. 따라서 우리나라의 경우 현재 이 Pyroprocess에 대한 연구가 활발히 진행되고 있다.

Echinacea purpurea is an important medicinal plant native of North America, which contains caffeic acid derivatives, alkamides, glycoproteins, and polysaccharides. For commercial roduction of bioactive compounds from Echinacea purpurea, adventitious roots were induced and proliferated in 5 and 20-liter bioreactors under various cultural conditions (Medium composition, inoculum density, air volume, light, temperature et al.). In a 5-liter bioreactor, more than 10-fold of biomass increment was achieved after 5 weeks of culture. Increases of root biomass and bioactive compounds were correlated with increased consumption of sucrose and macro/micro nutrients in the medium. Elicitations have been conducted with UV-C, NO, and SA to increase the accumulation of total polyphenolics, flavonoids and caffeic acid derivatives in the adventitious root cultures, which resulted in 1.2-1.6 times of increment. Based on the previous experimental results, 500-liter and 1000-liter scale bioreactors were applied for large scale cultures of Echinacea purpurea adventitious roots. Total root biomass of 3.62 kg and 5.05kg (dry weight) were achieved in a 500 L and a 1000 L bioreactor, respectively. The accumulation of 22.55 mg/g DW cichoric acid, 4.92 mg/g DW chlorogenic acid and 3.99 mg/g DW caftaric acids were also achieved from the adventitious root in a 1000-liter scale bioreactor.
