경강선의 평압가공성에 미치는 조직과 가공의 영향에 대한 연구
이인섭,김동훈,김원태 대한금속재료학회(대한금속학회) 1984 대한금속·재료학회지 Vol.22 No.5
Microstructure analysis and tensile test were performed to study the effects of microstructure and drawing on the flat rolling of high carbon steel wires. Critical reduction ratio in flat rolling increases due to the developed fibrous microstructure as drawing ratio increases, and is roughly proportional to the area reduction ratio in tensile test. Edge crack is formed at the angle of 45 degree to the rolling direction due to tensile stress. Critical width to thickness ratio of Stelmor treated wire is superior to that of the lead patenting treated wire. Sorbite created in the lead patenting treatment is considered to be deterious to flat rolling of wire.

A Giemsa C-banding method was used for the identification of somatic chromosomes and heterochromatic knob position in Korean indigenous waxy com (Zea mays L.). 5 inbred stocks were examined and their heterochromatic knob numbers ranged from 6 to 12. In comparison of homologous chromosomes of two stocks of YS-1 and MY-1, knob numbers, knob positions, arm ratios and relative length of chromosomes were different between the genotypes. The length of homologous chromosomes in YS-1 were generally larger than those of MY-1. The Giemsa method was proved to be useful for the identification of somatic chromosome and a C-banded diagram showing knob positions, arm ratios and relative length of chromosome could be used as a good tool to compare the characteristics of chromosomes of Korean indigenous waxy corn stocks. Giemsa C-banding방법으로 한국 재래종 찰옥수수의 핵형 및 염색체 상에 존재하는 knob의 수와 위치 등을 확인하고 모식도를 통하여 염색체의 특성을 나타내고자 재래종 찰옥수수 5개의 자식 계통 (inbred stock)을 조사하였다. knob의 수는 6-12개이었고 평균 9.2개이었으며 계통별로 차이가 있었으며, knob을 가지고 있는 염색체도계통별로 차이가 있었다. YS-1의 경우 6번, 7번, 8번 그리고 9번 염색체에서 knob을 가지고 있었는데, MY-1의경우 1번, 2번, 3번, 6번, 「번 그리고 9번 염색체에서 knob을 가지고 있었다. 염색체의 장완과 단완의 비율, 염색체의 상대적 길이 등을 비교해 보기 위하여 YS-1과 MY-1 두 계통을 조사해 본 결과 두 계통 간에 차이가 있었고, 염색체의 상대적 길이는 YS-1이 큰 것으로 나타났다. Giemsa C-banding법은 재래종 찰옥수수의 계통별 특성과 이를 이용한 계통 분류에도 효과적으로 이용할 수 있을 것으로 생각된다.

Korean local corn lines from various regions in the country were studied for the plant characters such as flowering days. plant height. growth rate. number of ears per plant. leaf size. brace roots and tillers. All the lines without exception were different in plant characters studied and the difference were also apparent among regions from where the original lines were obtained. The variation among lines and original regions indicated that the plant characters were quite dependent upon the magnitude of traditional cultural practices and other environmental factors such as precipitation or cropping systems in regions concerned.
水稻의 種子培養에 있어서 Japonica, Indica 및 雜種系統의 植物體 發達 및 Callus形成의 變異
李仁燮 慶星大學校 1990 論文集 Vol.11 No.2
To find the effects of auxin(2,4-D and NAA) on the root development, shoot development, and callus formation of Japonica, Indica, and their hybrid varieties, seed culture of brown rices of each ecospecies was conducted. The results obtained were as follows; Nagdong variety(Japonica)was more sensitive than Myrang 23(hybrid)and IR 50(Indica)to the plant growth regulators, and the effect of sensitivity(inhibition) was more serious to leaf than root. 2,4-D was more serious than NAA to plant development and callus formation of all ecospecies. The callus formation ability of Nagdong was higher than those of other varieties.

This study atempts to describe the usage of Korean grammar of a young child. The followings are the hypotheses of the study. First hypothesis: Principles of fitness and transformation. Second hypothesis: Principles of equiliburium and transformation. It is assumed that the child has had following three developmental stages. Stage Ⅰ: One-Word Sentences <S→Topic+intonational marker> Stage Ⅱ: few-words sentences <S→(Voc)+(NP)(VP)> She might have developed the stage Ⅲ through expansion and transformation of the previous stages. Stage Ⅲ (1) The vocative words come first in every sentence as an optional element. S→(Voc)+S^1_4 Voc→person/??m-ma, ap'a, ??n-ni/ S^1_4→S_1 Declarative sentence S_2 Interrogative Sentence S_3 Imperative Sentence S_4 Propositive Sentence (2) The intonational markers differentiate the sentences Intonational marker falling tone/long-Declarative rising tone/short-Interrogative rising tone/long-Imperative (3) The negative sentences have two types Ⅰ S→Neg+Nucleus Neg→/ani/anja/ Nucleus→NP VP NP+VP Ⅱ S→(NP_1)+(NP_2)+Neg+V Np_l→N-Psubj Np_2→N-Pobj Neg→/an/ V→Verb Ajective (4) The declarative sentences have the following rules 1. S→(Voc)+Np_l+Vp 2. Voc→Person/??m-ma/ 3. Np_l→N_1 -P_1 4. N_1→(Det_l)+N 5. Det_1→N+V-/Pal-s'is??n/ Ad+V-/s'uk-naon/ N-/j??-ki/ 6. P_1→Psubj 7. Vp→(Ad) V± Np_2+V± 8. Np_2→N_l-P_2 9.
