부생가스 기반 수소 정제시설의 정량적 위험성 평가에 관한 연구
신현국,김민주,정지운,하상준,최종호 한국가스학회 2023 한국가스학회지 Vol.27 No.4
부생가스 발생 및 이용현황보고서(2015)에 따르면 철강 사업에서 나오는 부생가스는 국내 연간 8,000만톤으로 추정된다. 이를 정제할 경우 다량의 수소 생산이 가능하여 수소 정제시설과 관련해 활발한 연구 개발이 진행 중이다. 본 연구에서는 부생가스 기반 수소 정제시설의 구성요소를 분석하고 위험요인을 조사하여정량적 위험성 평가(QRA)를 실시하였다. 위험도 분석 결과는 허용 가능 수준으로 도출되었으며 수소의 위험성을 고려한 시설물의 안전성 향상을 위한 기초자료로 활용할 예정이다. According to the Off-Gas Generation and Use Status Report (2015), Off-gas from the steel in- dustry is estimated to be 80 million tons per year in Korea. If this is purified, large amounts of hydrogen can be produced, so active research and development related to hydrogen purification facilities is underway. In this study, a quantitative risk assessment (QRA) was conducted by analyzing the components of a off-gas based hy- drogen purification facility and investigating risk factors. The risk analysis results were determined to be at an acceptable level and will be used as basic data to improve the safety of facilities considering the risks of hydrogen.

In order to obtain basic informations on F_1 hybrids of rape which are suitable at the southern part of Japan, 10 hybrids were grown from Oct. 1990 to Jun. 1991 at faculty agriculture, Kyushu University, Fukuoka, 812, Japan, and the evaluations were conducted using heterosis which were comparison between the performance of F_1 and that of parental average and heterobeltiosis which were comparison between the performance of F_1 and that of better parent. All the 10 crosses showed high degree of heterosis and heterobeltiosis in plant height and the maximum increase over better parent was 21%. Ten crosses showed high degree of heterosis and a crosses showed greater ear length than better parents. In case of number of branches per plant, all 10 crosses exceeded the parents. In case of number of brnches per plant, all 10 crosses exceeded the parental average and 8 crosses showed grater number of branches per plant than better parents. All the 10 crosses showed high degree of heterosis and heterobeltiosis in the number of pods per plant and the maximum increase over better parent was 7%. The performance of F_1 for pod length was similar to that of parental average and better parents. Pod setting density of all 10 hybrids was high degree of heterosis and heterobeltiosis of parental average and better parents. Some degree of heterosis and heterobeltiosis were observed in seed seeting rate only in 7 crosses. All the 10 hybrids produced higher garin yield than higher parent and the maximum increase over higher parent was 67%. Hybrids between early parent and late parent showed late flowering and falling blossoms date. However, in a crosses betwen late parents, the F_1 flowered 2 days earlier than the parents.

The pod dehiscence of rape is an important factor related to the harvest loss. To evaluate the varietal difference in the tendency of pod dehiscence, the breaking bending strengths of rape pod from 132 varieties were determined using a strain gauge type load cell. The breaking bending strengths were estimated treating each rape pod as a two-support beam and applying a dwonwared load at the center until the suture of pod breaks. Breaking bending strenths of the pods of easily dehiscent varieties were lower than those of medium and resistant varieties. Breaking bending strengths of pods measured by positioning the two lines of suture aligned vertically were lower than the measurements with the suture lines aligned horizontally. The positive correlation between the measurements with different positioning of pods was recognized at 0.01 probability level. Breaking bending strengths of the pod attached at upper part of main stem and primary branches were lower than those attached at medium and lower parts, and the mean value of those of the whole plant was about the same as the value of medium part. Therefore, it seems that the degree of pod dehiscence could be expressed by breaking bending strengths of the pods attached at medium part of the main stem and primary branch and with each pod positioned such that the lines of suture are aligned vertically. However, breaking bending strengths of the pod air-dried after harvest were lower than the values measured at harvest, and the positive correlation was recognized at 0.01 probability lvel. The breaking bending strengths were found to be positively correlated with width and thickness of pod, and the varieties resistant to pod dehiscence showed high values in the breaking bending strengths and thier width and thickness of the pod were larger. Rape cultivars, AB 120, Germany, Melchouski, Norin 35 and Naehan-yuchae showed higher resistant breaking bending strength of pod in the experiment. Therefore, it was concluded that AB 120, Germay, Melchouski, Norin 35 and Naehanyuchae were the most suitable cultivars as breeding material for higher yield and resistant pod dehiscence at the southern part of Korea.

Gibberellin(GA₃)處理에 依해서 誘起되는 浮稻의 幼苗에 있어서 節間伸長의 品種間差異
金晋鎬,井之上 準 順天大學校 1984 論文集 Vol.3 No.1
幼苗時에 있어서 浮稻와 非浮稻의 區別 및 浮稻의 節間伸長性에 對한 差異를 判定하는 檢定方法을 探求할 目的으로 GA₃의 葉面撒布에 依해 誘起되는 節間伸長의 位置에 對해서 檢討하였다. 供試材料는 "방글라데시" 産浮稻 181品種, "타이랜드"産浮稻85品種 및 非浮稻101品種이었다. 얻어진 結果를 要約하면 다음과 같다. 1. 第 3~5葉期에 GA₃1~1000ppm을 1回 葉面撒布하여 節間伸長이 誘起되었으나伸長이 誘起된 節間의 最低位置는 GA₃濃度가 낮을수록, 또한 節間伸長性이 낮은 品種일수록 높은 傾向으로 나타난다 2. "타이랜드" 産에 있어서 節間伸長이 良好한 品種과 不良한 品種 또는 非浮稻의 區別은 GA₃1000 또는 100ppm 1回의 葉面撒布處理에 依해서 伸長이 誘起된 節間 最低位置의 差異에 依해서 거의 區別될수 있었으나 節間伸長이 不良한 浮稻와 非浮稻의 區別은 困難하였다. 3. "방글라데시"産의 浮稻는 "타이랜드"産의 浮稻보다 GA₃에 依한 節間伸長의 誘起作用을 强하게 받았다. 따라서 GA₃100ppm의 葉面撒布에 依해서 誘起되는 最低伸長節間位置의 差異에 依해서 兩者를 區別할수 있었다. Internode elongation was induced during the seedling stage by foliar application of gibberellic acid (GA₃, 1-1,000 ppm) in floating rice and non-floating rice. The induction effect of GA₃was stronger in floating rice than in non-floating rice. Comparing with Bangladesh floating rice with Thai floating rice, the induction effect was generally stronger in the former than in the latter. In each of both floating rices, it was stronger in the varieties which have good elongation ability than in those with inferior elongation ability. But, the promotion of elongation of both leaf sheath and leaf blade by GA₃did not differ among Bangladesh floating rice, Thai floating and non-floating rices.
