Mature embryos of five oat genotypes were cultured to develop an efficient method of callus induction and plant regeneration. Murashige and Skoog(MS) and N6 media supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D) and kinetin were used for callus induction. Percentage of callus induction showed significant among the combinations of plant growth regulators. Callus induction showed high efficiency in medium containing 3 mg/$\ell$ of 2,4-D. The high frequency of callus induction was obtained in Gwiri37. For plant regeneration, calli induced from mature embryos were transferred onto MS and N6 media supplemented with combinations of 6-benzyladenine (BA) and naphthaleneacetic acid (NAA) for 5 weeks. Percentage of plant regeneration showed high in MS medium containing 0.2 mg/$\ell$ of NAA and 1 mg/$\ell$ of BA. The callus initiation medium affected the subsequent plant regeneration. Treatment with 3 mg/$\ell$ of 2,4-D, and 3 mg/$\ell$ of 2,4-D and 3 mg/$\ell$ of kinetin in callus induction media showed high frequency for plant regeneration. Plant regeneration frequency among the genotypes showed significant. Especially, Gwiri37 showed high regeneration frequency. Regenerated shoots were treated with 200, 350 and 500 mg/$\ell$ of indole-3-butyric acid (IBA) transferred onto half-strength MS medium without plant growth regulators. Treatment of shoots with IBA induced root formation rapidly.

In rapidly solidified $Al_{92-x}Nd_8$(Cu,Ag)x ($0{\leq}X{\leq}10at%$) alloys, amorphous single phases were obtained in the ranges of $Oat%{\leq}X{\leq}4at%$ for Al-Nd-Cu system and $Oat%{\leq}X{\leq}6at%$ for Al-Nd-Ag system, respectively. Mesoscopic structures consisted of amorphous and crystalline phases were formed above solute ranges. It was founded that the mesoscopic structures were also formed near 1st exothermic peak on DSC curve by aging in amorphous single phase alloys. For example, amorphous $Al_{92-x}Nd_8$(Cu,Ag)x (X=2.4at%) alloys containing nanoscale Al particles and compounds, i.e., mesoscopic structure, exhibited higher tensile fracture strength(${\sigma}_f$) than those of amorphous single phase alloys with the same composition. The ${\sigma}_f$ showed a maximum value in the $V_f$ ranges of 10~15%. The reason is presumed that the nanoscale precipitates which have higher mechanical strength compared with the amorphous phase with the same composition act as an effective resistance to shear deformation of the amorphous matrix.

고추 역병균의 균사생장 및 유주자낭 형성에 미치는 광선 및 pH의 효과를 조사하기 위하여 PC7971외 2균주를 공시하여 다음과 같은 결과를 얻었다. 1. 역병균의 생육적온은 $25^{\circ}C$ 내외이었고, 2. 생육적정 pH는 6.0부근이었다. 3. 유주자낭 형성에는 광이 필요했으며 $20^{\circ}C$에서는 2,000Lux의 광도가 유주자낭 형성에 가장 효과적이었고, 4. 광처리후 56시간까지 급속한 형성을 보였다. 5. Oat meal배지와 V-8 Juice 배지가 Bean meal배지보다 현저히 많은 유주자낭을 형성하였다.

Most of the proceeded research of jogories in the Goryeo era are about the total clothing system of the men and women's dress and not many have studied of the developing process of the jeogories specific structures. Therefore, the purpose of this study is to figure out the origin and the alteration of a git, gil, seop and gorem which forms a jeogori after the Unified Shilla era. The range of this study os from 918 to 1392, Goryeo era and 80 pieces 7 portraits and 5 Buddhist relics were for references. This study reached the following conclusions. First, oat git, gil, seop, somae and gorem forms the Goryeo era's jogori. Second, as the length of the joegori got shorter then the past, the ryeongem also got shorter and changed to an oatgit. Third, as most of the opening side of the jeogori started to fix on the right. Forth, an extra cloth attached on the gil developes a seep that be originates in Unified Shilla when get shoter. Fifth, there were wide and very long sleeves that came all the way down to the hand, narrow sleeves and long sleeves. Sixth, Goryeo era's jeogori had ribbons and cloth buttons to fix the form instead of a belt.
