기생잡초 스트라이가 허몬티카(Striga hermonthica)는 사하라사막 이남의 아프리카 지역에서 곡물생산에 가장 심각한 피해를 주는 생물학적 장애요인이다. 본 연구는 악마의 풀에 견디면서 저항성을 띄는 20개의 자식계통과 7개의 합성품종을 광범위한 유전자원들로부터 1979-1994년 사이에 국제열대농업연구소(IITA)에서 개발하였는데, 이들은 여러 개의 기주식물로부터 수집된 기생잡초 종자를 인공적으로 접종한 상태에서 육종되었다. 육종방법은 1수 1열 방법과 계통 자체 선발, 검정교배검정법을 적용했다. 검정시험은 서부아프리카의 나이지리아 남부 기니사바나(반건성지대), 북부 기니사바나와 코테디부아와 중부아프리카의 카메룬에서 이루어졌다. 스트라이가 침입상태하에서 저항성 교잡중과 합성품종은 약한 대비품종 보다 각각 250% 와 50%의 수량증가를 보였다. 스트라이가와 공생하는 이들 품종들은 동시에 아프리카 옥수수 재배에 가장 큰 문제가 되고 있는 옥수수 위축바이러스병(maize streak virus)에도 저항성을 띈다. Obligate parasitic weed Striga hermonthica (Del.) Benth is one of the major biological constraints to cereal crop production in sub-Saharan Africa. Twenty inbred lines and seven synthetics tolerant and resistant to Striga hermonthica (STR) were developed between 1979 and 1994 from diverse germplasm using artificial infestation with seeds of the parasitic weed obtained from various hosts. The breeding procedure included ear-to-row, line per se selection and testcross evaluations for the determination of combining ability. Evaluations were carried out at test sites in the Southern Guinea Savanna, Northern Guinea Savanna and Sudan Savanna of Nigeria and Cote´d' Ivoire (West Africa) and Cameroon (Central Africa). Under Striga infestation, STR hybrids and synthetics produced 250 and 50% more grain yields, respectively, than susceptible checks. The STR hybrids and synthetics are also resistant to maize streak virus the most prevalent disease of maize in sub-Saharan Africa.

These days leakage incidents of toxic materials cause serious effects on the nearby residents as well as the workers around the accidents accompanying massive material losses and human damages through widening influencial areas. The risk measure through adequate quantitative analysis as well as the qualitative analysis of the leakage incidents of toxic materials becomes an urgent issue. The damage, of the leakage incident on the surrounding area of the dangerous toxic material facilities was calculated quantitatively by adopting several models in this research. First, the calculations of the leakage velocity from the factories were performed by using source model for the assessment of the influential area, and the damages on the nearly residents were calculated by using the dispersion model and the effect model. The probability of the incidents was computed based on $quot;The manual for classification and priorization of major incidents$quot; published by IAEA(International Atomic Energy Agency). Above calculated damage area and incident probability were further adopted in this study to induce the individual and societal risk, quantitatively. The calculated data of the real incident of the toxic material leakage showed reasonable agreements to the actual damage of the incidents, which showed a validity of this study. The result of this study might be a helpful measure for predicting damages and preparing safety systems for similar kinds of incidents.

기계적 합금법으로 제조된 Al-Nb 합금 및 Al-Al3Nb 복합재료 압출재의 인장 특성

Tensile behavior of mechanically alloyed(MA) Al-5 wt.%Nb alloy extrusion was examined at various temperatures and strain rates. The tensile ductility of MA Al-5wt.%Nb alloy extrusion was greatly reduced with increasing temperature and/or decreasing strain rate. The SEM observations of side and fracture surfaces of tensile fractured specimens demonstrated that the overall void density formed during deformation was considerably reduced, along with the sign of decreased plasticity around the dimples on the fracture surface. To understand the effect of grain size on the deformation behavior of submicron grain sized alloys, Al-5 vol. %Al₃Nb composite extrusions with different grain sizes were fabricated and tensile tested at different temperatures. The present study confirms that the reduction in tensile ductility of submicron grain sized alloys at elevated temperatures are undoubtedly related to the grain size. Fast dynamic recovery rates, due to the lack of dislocation substructures, in submicron grain sized alloys appears to be responsible for the elevated temperature reduction in tensile ductility.

Mycobacterium Avium - in tracellulare Complex 와 M . Fortuitum 에 의한 폐항산균증(肺抗酸菌症) 3예

Two cases of pulmonary disease in a 54 year-old female and a 70 year-old male patient due to Mycobacterium avium-intracellulare complex (MAIC) and a case of pulmonary infection in a 69 year-old male patient due to M fortuitum (MF) were found recently in this institute. All three patients bad a long history of anti-tuberculous chemotherapy because they were initially diagnosed as pulmonary tuberculosis. A 70 year-old male patient infected with MAIC had an unsuccessful chemotherapy history of isoniazid (INH), para-aminosalicylic acid (PAS) and streptomycin (SM) with an incomplete, temporary, symptomatic improvement, for three years since 1964 when he was first diagnosed as pulmonary tuberculosis on physical examination. A 54 year-old female patient infected with MAIC also had an unsuccessful chemotherapy history with the various anti-tuberculous drugs since 1958. Both patients discharged large number of MAIC in their sputum specimens for at least more than one year, but no M tuberculosis at all. A 69 year-old male patient infected with MF was diagnosed as moderately advanced pulmonary tuberculsis in 1977. Combined chemotherapy with INH+PAS+pyrazinamide (PZA) improved his clinical symptoms, however, his chest radiograph was deteriorated again in 1980 one year after he stopped therapy. Therefore he started chemotherapy again with INH+ethionamide (TH)+cycloserine(CS) but no improvement was noticed. MF was cultured from his sputum in August 1983 and he continuously discharged the same baeilli until last examination of January l982. Whether all three patients were initially infected with nontuberculous mycobacteria or complicated with predisposing tuberculosis was not clear because there were no reliable bacteriological Examination records.

Zr 첨가가 Cu-6Ni-2Mn-2Sn-2Al 합금의 인장 및 부식 특성에 미치는 영향

김상식,김창주,한승전,김기원,서영익 대한금속재료학회(대한금속학회) 2001 대한금속·재료학회지 Vol.39 No.5

In the present study, tensile and corrosion properties of Cu-6Ni-2Mn-2Sn-2Al alloy, with and without Zr addition, were examined. Even though the addition of Zr refined the grain structure of Cu-6Ni-2Mn-2Sn-2Al alloy, the improvement in tensile property was not significant. The addition of Zr, however, greatly improved the corrosion resistance of the alloy in NaCl aqueous solution. The potentiodynamic study clearly demonstrated that the Zr addition substantially reduced the current density of Cu-6Ni-2Mn-2Sn-2Al alloy in 3.5% NaCl solution. The enhanced corrosion resistance with Zr appeared to be due to the reduced Sn segregation during solidification. The stress corrosion cracking study reflected the result of potentiodynamic study in the present study. The Zr-added specimen showed no reduction in tensile ductility after exposure to 3.5% NaCl aqueous solution for 20 days with an applied stress of 80% yield strength, while the tensile elongation of non-Zr added specimen was reduced approximately 10% after the exposure. The reduced Sn segregation during solidification in believed to be the main reason for the improved corrosion property of Zr-containing Cu-6Ni-2Mn-2Sn-2Al alloys.

Analysis on the study for the sodium fire mitigation was carried out using the CONTAIN-LMR code. Sodium loop building was partitioned into the many cells, in which the safety venting systems were installed for the purpose of improving the sodium fire safety and minimizing its effect on the sodium loop building. The effects of sodium fire on sodium loop building partitioned into the many cells and not partitioned were investigated. The peak pressure and temperature of each cell accompanied by sodium fire in sodium loop building partitioned were lower than those of sodium loop building not partitioned. In the case of partitioning sodium loop building, the pressures, temperatures and aerosols into cells were transferred through propagation path of CONTAIN-LMR sodium fire model simulated by this study, and the effect of sodium spray fire on sodium loop building was mitigated by partitioning building. In addition, the excessive rise of pressure into cells was prevented by installing the over-pressure exhaust valve and under-pressure exhaust valve on the flow path between cells.
