具轄本,朴鄭學,司空鍵 東亞大學校 1990 東亞論叢 Vol.27 No.1

Aromatic compounds such as Polyparaphenylene(PPP) and Polyparaphenylenvinylene(PPV) were polymerized by chemical and electrochemical synthesis. The electrical properties with various dopants and concentrations for the PPV and PPP were studied. The results are as follows: 1) The conductivities of PPV with BF₄dopants and I₂doped PPP were much incresed(i.e., 10 adn 6 orders, respectively) than those of without dopants. 2) The conductivities of PPV and PPP with NH₃gas were much increased(i.e., 2 and 10 orders, respectively) than those of without NH₃ gas. 3) The variations of ESR line width and spin density were in good agreement with those of polaron and bi-polaron models. As a summary, PPV and PPP were made by chemical and electrochemical synthesis could be appropriate for the gas sensors.

Influence of Seeding Dates on Ecological Response and Seed Production in Radish Cultivars This investigation was conducted to determine the influence of seeding dates on ecological response and seed production in radish. Cultivars varying in ecotype or Harubang, Seouldaehyung, Yeongkwang and Shinyeongkwang were seeded ten times at intervals of 15days from November 20. The results obtained were summarized as follows: 1. Days to bolting and days to flowering were prolonged in early seeding and shortend in late seeding. The days were long in Daehyung. medeum in Harubang and short in Yeongkwang and Shinyeongkwang. 2. Plant height was greater in Harubang than in the others on every seeding date. The number of branches was reduced as the seeds were sowed late and that of Harubang was large but there were not different between the other cultivars. 3. Inflorescence length had no difference between seeding dates, having significant differences between the cultivars. 4. The number of pods per inflorescence was large in Harubang and Seouldaehyung. The number of seeds per pod was greatest in Daehyung and late seeding reduced the number. One hundred seed weight was light in lated seeding. 5. Seed yield per plot was high in Harubang and there were not significant differences between the other cultivars. As the seeding was late, the yield was reduced. 6. Root weight was increased as seeding date was late. The weight in Daehyung was increased rapidly after seeding on March 5. 7. Seed yield in the four cultivars tested had positive correlations with days to bolting and days to flowering, that is, the longer days to bolting and flowering were, the higher the seed yield was.

본 試驗은 1996年 11月부터 1997年 6月까지 濟州大學校 農科大學 財屬農場에서 飼料用 穀實귀리 올귀리 등 19品種을 供試하고 施肥量 4水準을 處理하여 施肥量에 따른 각 形質의 生態變化, 遺傳率, 遺傳相關, 表現形相關, 環境相關 및 經路係數를 分析한 結果는 다음과 같다. 1. 遺傳率은 出穗日數, 稈長, 穗長, 稈直徑, 穗當粒數, 千粒重, 株當收量에서 높게 나타났고, 生育日數, 株當分蘗數, 株當穗數, 穗重은 중간 程度였으며 有效分蘗率은 낮은 편이었다. 2. 施肥量의 變化에 따른 遺傳準의 變動은 穗當粒數와 千粒重이 가장 적었고, 生育日數, 株當分蘗數, 穗重, 株當穗數, 有效分蘗率은 變動이 甚하였으며 株當收量의 遣傳率은 增肥區에서 가장 높았다. 3. 株當收量과 遺傳相關이 높게 나타난 것은 株當分蘗數, 株當穗數 및 穗重이었고 出穗日數와는 높은 負의 相關을 보였다. 4. 施肥量에 따른 遣傳相關의 變動에서 穗重과 穗當粒數와의 遺傳相關은 施肥量이 增加함에 따라 높아지는 傾向이었고, 柱當分蘗數와 株當穗數, 柱當收量과 株當 分蘗數, 有效分蘗率과는 增施할수록 遺傳相關이 낮아지는 傾向이었다. 5. 株當收量과 表現形相關이 높게 나타난 것은 株當分蘗數와 株當穗數였으며, 環境相關은 施肥量의 變化에 일정한 傾向이 없었다. 6. 株當收量에 대한 主要形質의 經路係數 分析 結果, 株當收量에 대해 直接效果가 컸던 形質은 無肥區에서는 株當穗數가, 減肥區에서는 株當分蘗數가, 標準肥區에서는 株當穗敎가, 增肥區에서는 穗重이 가장 컸다. 7. 大部分의 處理에서 穗重과 株當穗數가 收量에 대한 直接效果가 크고, 遺傳相關도 높아서 이들의 形質이 收量에 크게 影響을 주었다. This experiment was conducted on the Experimantal Field of Cheju Univ. from November 1996 to June 1997. Object of this study was to clarify the fertilizer responses and to estimate genotypic, phenotypic and environmental correlations, heritabilities and path coefficients for some agronomic characters using 19 hulled oat cultivars including Olgwiri in accordance with different fertilizer levels. The heritabilities estimated for the days to heading, the culm length, the panicle length, culm diameter, the number of kernels per panicle, 1000-kernel weight and the grain yield per plant were high, and those for the days to maturity, the number of fillers and panicles per plant, and the panicle weight were medium, and that for the rate of effective tillering was low. Changes in heritability for the number of kernels per panicle and the 1000-kernel weight were small, and those for the days to maturity, the number of tillers and panicles per plant, panicle weight and the rate of effective tillering varied greatly on different fertilizer levels. With increasing fertilizer level, heritability of grain yield per plant was increased. The gram yield showed highly positive genetic correlations with the number of tillers per plant, with the number of panicles per plant and with the panicle weight, and, showed the negative correlation with the days heading. With increasing fertilizer level, the genotypic correlation coefficient between the panicle weight and the number of kernels per panicle was increased, and the genotypic correlation coefficients between the number of filler and panicles per plant, and between the grain yield and the number of fillers per plant and the rate of effective tillering were decreased. The phenotypic correlation coefficient between the grain yield and the number of tillers per plant and panicles per plant showed highly positive values, and the changes in phenotypic correlation coefficient for different fertilizer levels had no definite tendency. The characters of which direct effect estimates were high versus the grain yield per plant were the number of panicles per plant on non-fertilizer plot, the number of tillers per plant on decreased fertilizer plot, the number of panicles per plant on standard fertilizer plot, and the panicle weight on increased fertilizer plot. Genotypic correlations and direct effects of the panicle weight and the number of panicles per plant versus the grain yield per plant were high in most treatments, that is, these characters had an influence on the grain yield.

These studies were carried out to clarify the ecological response and the changes of selection criteria in accordance with the difference of seeding dates in pea (Pisum sativum L.) The studies were conducted to estimate genotypic, phenotypic and environmental correlations, heritability, and path coefficient for the major agronomic characters using 17 cultivars including Sparkle which were seeded on October 15, November 4, February 20 and March 11 in Cheju Island, Korea. The result obtained were summarized as follows: 1. The days from seeding to flowering and days from seeding to maturity were prolonged in early seeding and shorted in late seeding, the middle of October was the optimum seeding time to get the highest yield and the agronomic characters of the yield components in Cheju Island. 2. Early maturing cultivars were Sparkle, Jeonbug, Jeonkwang 30 and Sojeong, and late muturing cultivars were Frescory, Chejujerae Ⅰ, Ⅱ, Alderman, Namuradaehyup and Laseui. 3. Stem length was longer (50cm) in winter seeding than in spring. The short stem cultivars (70-100cm) were Sparkle, Profinos R. S. Thomas Laxton, Jeonbug and Alderman, and the middle stem cultivars (110-140cm) were Frescory, Chejujerae Ⅱ, Laseui, Namuradaehyup and Rondo, the other cultivars were 140-200cm in stem lenght. 4. As pea were seeded early, the number of branches per plant increased. The numerous branch cultivars were Frescory, Chejujerae Ⅰ, Ⅱ, Kwangdojeokhyup, Alpine and Namuradaehyup, and the others were small branch cultivars. 5. Pod length and pod width had no change with the difference of seeding dates, but long pods were 8cm to 9cm and short pods were 6cm to 7cm. 6. As the pea were seeded late, the number of pods plant decreased greatly, but cultivars with the numerous pod were Chejujerae I. Targ, Frescory, Alpine, Thomas Laxton and Alderman. 7. The number of seeds per pod had no change with the difference of seeding dates, the large number of seeds were 6 to 7 and the small mumber were 4~5. 8. Weight per 100seeds of pea was decreased in late seeding, cultivars with heavy seed were Laseui (26.03g), Kwangdojeokhyup (24.0g) Chejujerae Ⅱ(22.43g) and Sparkle (20.43g), and cultivars with light seed were Thomas Laxton (14.63%), Frescory (14.7g), Daejung 11 (14.95) and Jeonbug (14.95g). 9. The shell weight of pea in early seeding was increased, the average shell weight in spring seeding was lighter than in winter seeding. 10. The weight of seed per plant in early seeding was increased, but that was decreased greatly in late seeding, average seed weight was 56% lower in spring seeding than in winter seeding. High yielding cultivars in winter seeding were not always high in spring seeding High yielding cultivars in winter seeding were Laseui. Targ, Chejujerae Ⅱ and Thomas Laxton, and high yielding cultivars in spring seeding were chejujerae Ⅰ, Namuradashyup, Kwangdojeokhyup and Alderman, and high yielding cultvars for both spring and winter were Chejujerae Ⅰ, Kwangdojeokhyup and Namuradaehyup. 11. The Heritabilities estimated for the days from seeding to flowering, from flowering to maturity, from seeding to maturity, 100 seed weight, pod length and pod width were high, while the number of pods and the number of branches per plant showed medium values, the seed weight and shell weight per plant and the number of seeds per pod were small values. 12. Relationships between the characters differed with seeding dates and the changes in correlation coefficient had no definite tendency. As for the genotypic correlation, the seed weight was highly correlated with the shell weight and the number of pods per plant in the both seasons and with 100 seed weight in winter. 13. The phenotypic correlations were showed high positive values when genotypic correlation were high, The most phenotypic correlation values were lower than genotypic correlation. The genotypic correlations and phenothpic correlations were generally showed the same directions in positive and negative. 14. Direct effect estmates of the characters versus seed weight were not high at all the seeding dates, but the days from seeding flowering, the shell weight per plant, 100 seed weight and the number of pods per plant had a large influence. 15. The genotypic correlation coefficient and direct effects of the shell weight per plant, 100 seed weight and the number of pods per plant versus the seed weight showed high positive values, as a result, it was thought that these characters were useful selection criteria for the seed yield.

참깨의 育種 效率 增大를 爲하여 組織培養技術의 利用을 위한 基礎的 硏究로서 品種에 따른 部位別 칼루스 形成과 植物體 形成에 미치는 影響을 調査하였던 結果는 다음과 같다. 1. 單獨處理에서는 NAA가 칼루스나 莖頂 및 根分化에서 IAA보다 優秀하였다. 2. MS 培地에 kinetin 2.0mg/ℓ 處理한 것에서 89%, NAA 0.5mg/ℓ 處理한 것에 完全 植物體 分化率은 62%로 가장 높았다. 3. Auxin系의混合 處理에서는 NAA와 kinetin 混合이 NAA와 BA 混合보다 完全 植物體 分化에 效果的이었으며 特히 NAA 0.5mg/ℓ와 kinetin 0.5mg/ℓ 混合 處理에서完全 植物體 分化率이91%로 가장 效果的이었다. 4. NAA와 kinetin 混合 處理時, NAA 濃度增加는 莖頂 分化를抑制하나 根分化에는 큰 影響을 미치지 않았다. 5. 生長調節物質의 混合 處理에서 NAA 0.5mg/ℓ, IAA 0.5mg/ℓ, kinetin 2.0mg/ℓ는 98%의 分化率을 보여 가장 效果的이었다. 6. 品種間 칼루스 形成은 단백깨에서 삼다 보다 높은 形成率을 보였다. This study was conducted to study the effect of NAA, IAA, 2.4-D, BA and kinetin on the organ culture from the cotyledon and hypocotyl in sesame. (Sesamum indicum L.) The results obtained are summarized as follows. In single treatment of NAA and IAA, NAA was better in shoot and root differentiation than IAA. Among the various hormones used, kinetin 2.0mg/ℓ was found to be the highest in shoot differentiation and NAA 0.5mg/ℓ in whole plant induction percentage. The whole plant induction percentages were 91% and 47% in the combinations of NAA 0.5mg/ℓ+kinetin 0.5mg/ℓ and NAA 0.5mg/ℓ+BA 0.5mg/ℓ respectively. Due to the interaction between NAA and kinetin, increase of NAA concentration reduced the shoot differentiation but did not influence the root differentiation significantly. The most desirable medium was the MS medium containing NAA 0.5mg/ℓ+IAA 0.5mg/ℓ+kinetin 2.0mg/ℓ. The whole plant induction percentage was 99% in this medium. Danbaeg was better for callus induction than Samda.

Subjects consisted of 75 boys and girls(37 in the control group and 38 in the treatment group) in the 4th grade of elementary school, The results showed as follows. The proportion of boys(53.3%) was a little higher than that of girls(46.7%). In their mother's age, the thirties and forties were 66.7% and 33.3%, respectively. 61.3% of mothers have jobs and 86.7% of mothers prepare meals. The degree of nutritional knowledge in treatment group after education was significantly increased in all concepts, however, the degree of control group appeared significant increase (p<0.05) in only two concepts, such as "snack" and "one-sided diet". When the level of nutritional knowledge was divided into 4 four classes(excellent, good, fair, poor), the treatment group showed a significant increase in "excellent" from 5.5% to 73.7% after education. These findings indicate that well-designed program for nutrition education can be help to change food habit, and also children's education helps them to grow and to live as a healthy adult. The performance of educational program for preventive nutrition is more beneficial for children than for the adults based on the cost reduction and effect of this education.

파종기 및 재식밀도의 차이가 땅콩의 수량형질에 미치는 영향

趙南棋,金翰琳 제주대학교 1971 논문집 Vol.3 No.-

본 연구는 땅콩의 파종기 및 재식밀도의 변동에 의한 주요 수량형질의 변화를 구명하기 위하여 수행되었다. 천엽반립을 공시품종으로 하여 파종기를 5월 7일부터 7월 7일 까지 15일 간격으로 하고, 재식밀도는 40 ×20, 50 ×25, 60 ×30, 70 ×35, 80 ×40㎝로 한 4 반복의 분할구 배치법에 의하였다. 얻어진 주요 결과는 다음과 같다. ① 발아 및 개화에 소요되는 일수는 파종기가 늦어짐에 따라서 점차 단축되었으다 재식밀도값에는 차이가 없었다. ② 주경의 길이 및 분지의 길이도 일찍 파종한 것에서 길고 늦게 파종할수록 짧았다. 그러나 재식밀도간에는 유의의 차를 인정할 수 없었다. ③ 분지수는 파종기나 재식밀도에 차이를 인정할 수 있으며 재식밀도가 높을수록 분지수가 적고 일찍 파종한 것은 분지수가 많았다. ④ 경엽중은 조기 파종한 것일수록 무겁고 밀식일수록 가벼우며 이 두 요인의 상호작용에도 유의성이 인정되었다. ⑤ 1주당 협실중은 파종기별, 재식기별, 및 이들의 상호작용에도 유의의 차가 있고 일찍 파종하고 소식일수록 1주당 협실중이 무거우나 10a당 협실중은 밀식이고 조기에 파종할수록 증가하였다. ⑥ 협실비율은 늦게 파종할수록 낮아지는 경향이었다. ⑦ 1주당 종실중도 조기 파종이고 소식일수록 증가하지만 10a당 종실량은 일찍 파종하고 밀식일수록 증가하였다. 따라서 10a당 수량은 5월 7일 파종하고 40 ×20 : 50 ×25㎝인 구에서 가장 많았다. This study was conducted to investigate the variation of some peanut characters on different seeding dates and in different plant densities. The seed of Chunyup-semirunner which was used as a test variety were sown on 5 different dates in 15 day intervals from May 7th, to July 7th, and 5 plant densities were practiced as 40 ×20, 50 ×25, 60 ×30 70 ×35, and 80 ×40㎝. The abov-described treatments were estabished in a split plot design of four replications. The results obtained are summarized as follow: 1) Days from seeding to germination and to flowering were shortened in accordance with delay of seeding date. But there were no difference among each of plant densities. 2) Plants seeded early were increased in their main stem length and branch length, but no significant difference was found among the plant densities. 3) Dence seeding and late seeding resulted in decreasing the number of their branch. 4) Late seeding and dense seeding rate decreased the plant weight, and significant defference could be found in interaction between plant density and seeding date. 5) There were significant differences in pod weight per plant among the seeding dates, among the plant densities, and among the interaction between them. 6) The varience ratios for seeding dates, for plant densities, and for the interaction between these two factors were significant in pod weight per plant. Pod weight per plant was heavy in early and thin seeding plots, but early and dense seeding increased pod weight per 10a. 7) Seed weight per plant was increased in early and thin seeding plots, and seed weight per 10a was increased in accordance with early and thick seeding. This tendency on seed weight per 10a was most prnounced in the plots seeded on May 7th, in 40 ×20 and 50 ×25㎝.

A topic of this study is focused on the electrical properties by utilizing thermally stimulated current and the time-of-flight method for conducting polymers such as PCPA and PPS. The mobility of carriers between electrodes inserted polymer was measured by Scher-Montroll plot. As a summary, it is shown that the conductivity of the polymer was strongly dependent on high affinity I₂or TCNQ addivities. The reason for increasing of conductivity is believed that the carrier density and mobility of polymer by adding I₂for PCPA were increased.
