박종성,PARK Jong Seong 한국응용곤충학회 1962 한국식물보호학회지 Vol.1 No.-

1) 강력한 위조독소(Wilt toxin)인 Fusaric acid를 생성하는 것으로 알려진 참깨$\cdot$시들음병균(Fusarium oxysporum f. vasinfectum)의 배양여액이 참깨의 종자발아 및 발아후의 유식물의 생육에 미치는 영향을 구명하기 위하여 이 시험연구에 착수하였다. 2) Fusarium oxysporum f. vasinfectum의 5종의 계통의 배양여액은 모두 참깨종자의 발아를 억제하고 종자의 흑변, 괴사를 초래한다. 3) 공시균의 어떤 계통의 배양여액에 대한 참깨종자의 발아반응에 있어서의 품종간 차이는 없다. 4) 공시균의 5종의 계통의 배양여액이 참깨종자의 발아를 억제하는 독성에는 뚜렷한 차이가 있다. 5) 공시균의 5종의 계통의 배양여액을 첨가한 육묘상에서는 발아후의 참깨유식물의 뿌리나 줄기의 신장이 다 같이 억제되며 조직은 흑변, 괴사하게 된다. 그러나 배양여액을 $10\%$ 첨가한 육묘상에서는 줄기의 신장생장 약간 촉진되는 경향이 있다. 6) 공시균의 배양여액을 $1\%$ 내지 $1\%$ 첨가한 Knop Solution에 본엽이 생기지 않은 참깨 유식물을 배양하면 참깨의 뿌리나 줄기의 신장생장이 억제되고 제2본엽이 전개할 때까지에 줄기나 잎자루나 연화, 흑변, 괴사하며 제1본엽에는 맥간에 염갈색반문이 형성되고 제2본엽은 권축, 흑변, 괴사하며 특히 제2본엽에 나타나는 병상은 포장에서 나타나는 참깨의 잎의 위조병징과 흡사하다. 7) 공시균의 5종의 계통간에 나타나는 배양여액의 독성의 차이는 공시균의 각계통자체의 기생에 의한 병원성의 차이와 일치하지 않는다 1) The purpose of the present study is to investigate the effects of culture filtrates of Fusarium oxysporum f. vasinfectum which is known to produce fusaric acid (wilt toxin) on the germination of sesame seeds and the growth of sesame seedlings. 2) Culture filtrates of Fusarium oxysporum 1. vasinfectum used in this study strongly or weakly inhibited the germination and bring about necrosis accompanying black discoloration of sesame seeds. 3) Varietal difference of sesame in the germination response on the culture filtrates of Fnsarium oxysporum f. vasinfectum is not shown in this study. 4) This study reveals that differential five strains of Fnsarium oxysoprum f. vasinfectum used in this study differ greatly in the toxicity of culture filtrates inhibiting the germination of sesame seeds. 5) In the seedling bed added with culture filtrates of Fnsarium oxysporum f. vasinfectum, the growth of shoot as well as root system of sesame seedlings are notably inhibited and necrotic black discoloration appear on both shoot and root system. But in the seedling beds added with weaker concentration of culture filtrates $/(10\%)$ the growth of shoot is slightly promoted. 6) In culture of sesame seedlings with Knop's solution containing 1 to 3 per cent culture filtrates, the growth of shoot as well as root system are slightly retarded" and till the time of development of the third leaves the whole stem and leaf petiole tissue are weakened so that they become thread like accompanying brown discoloration, interveinal light brown area appear in the second leaves, and the third leaves curl from both sides towards the middle with necrotic brown discoloration, especially symptoms of injury on the third leaves are nearly similar that of the leaves of wilted sesame in the field. 7) A pararell relationship is not found between toxicity of culture filtrates and pathogenicity of five differential strains of Fnsarium oxysporum f. vasinfectum used in this study.

과공정 Al-Si 합금의 열팽창거동과 기계적 성질에 미치는 미세조직의 영향

박종성,이정근,김명호 ( Chong Sung Park,Jeong Keun Lee,Myung Ho Kim ) 한국주조공학회 1997 한국주조공학회지 Vol.17 No.4

N/A The egects of changes in microstructure of Si phase on the thermal expansion coefficients(CTEs) and tensile properties of the hypereutectic Al-Si foundry alloy(A390) were investigated experimentally. Specimens were prepared by various fabrication processes, such as a permanent mold casting, a squeeze casting and a spray casting process, and subsequently hot-extruded. CTEs of the spray-cast specimen were found to be about 10% lower than those of the permanent mold-cast specimen, and the CTEs of the hypereutectic Al-Si alloy(A390) were changed proportionally with the size of Si phase. Ultimate tensile strength of the spray-cast and hot-extruded specimen was dramatically improved about 100% with improved elongation, compared to that of permanent mold-cast specimen. These improvements are mainly attributed to the reduction in size and aspect ratio of the brittle Si phase, and the elimination of the microvoids/porosities formed during casting.

분사주조법에 의한 저열팽창 알루미늄합금의 제조

박종성,이정근,김명호 ( Chong Sung Park,Jeong Keun Lee,Myung Ho Kim ) 한국주조공학회 1997 한국주조공학회지 Vol.17 No.3

N/A In order to fabricate lower thermal expansion aluminium alloys, the effects of microstructural parameters such as the volume fraction of SiC_p and the shape and size of Si phase on the coefficient of thermal expansion(CTE) of the spray-cast and hot-extruded hypereutectic Al-Si(A390) alloy composites were investigated experimentally. The CTEs of hypereutectic Al-Si (A390) alloy were changed proportionally with the size of Si phase. Ultimate tensile strength, elongation and Young`s modulus of the spray-cast and hot-extruded specimen were improved dramatically compared to those of the permanent mold-cast specimen. Although Young s modulus of the spray-cast and hot-extruded specimen was improved highly effectively by addition of SiC_p, no improvement was observed for the UTS and elongation. Spray-cast and hot-extruded hypereutectic Al-Si (A390) alloy reinforced with 20vol.%SiC_p exhibits a CTE equivalent to stainless steel.

분사주조한 입자강화 알루미늄 복합재료의 미세조직 특성

박종성,이인우,김명호 ( Chong Sung Park,In Woo Lee,Myung Ho Kim ) 한국주조공학회 1994 한국주조공학회지 Vol.14 No.6

N/A Aluminium-silicon alloy(JIS AC8A) matrix composites reinforced with SiC particles were fabricated by spray-cast forming process, and the microstructure of powders and preforms produced were studied by using an optical and scanning electron microscopy. SiC particles were co-sprayed by mixed phase injection method during the spray casting process. Most of the composite powders formed by this mixed phase injection method exhibit morphology of particle-embedded type, and some exhibits the morphology of particle attached type due to additional attachment of the SiC particles on the surface of the powders in flight. The preforms deposited were resulted in dispersed type microstructure. The pre-solidified droplets and the deposited preform of SiC-reinforced aluminium alloy exhibit finer equiaxed grain size than that of unreinforced aluminium alloy. Eutectic silicons of granular type are crystallized at the corner of the aluminum grains in the preforms deposited, and some SiC particles seem to act as nucleation sites for primary/eutectic silicon during solidification. Such primary/eutectic silicons seem to retard grain growth during the continued spray casting process. It is envisaged from the microstructural observations for the deposited preform that the resultant distribution of SiC injected particles in the Al-Si microsturcture is affected by the amount of liquid phase in the top part of the preform and by the solidification rate of the preform deposited.
