It shows a marked trend increasing the products of organic agriculture with growing interest in peoples health and safe foodstuffs. This is in the cause of the consuming public using habitually of safety and tasty organic agricultural products for reasons of environment pollution, environment hormone and etc. Now in Korea, organic agricultural products must be approved by our government of its quality, there fore organic agricultural products, that of transition period, non- chemicals agricultural products and less chemicals agricultural products are in cultivation separately. With the increase in number of consumers in future, we have to extend the products of the organic agriculture and have to control more strictly the quality guaranteed. Also, we must grope for developing of our organic agricultural products so that our producer can work with a strong will to attain self-sufficiency of our foodstuffs, paying our influence of environment.

This paper presents a method to reduce hysteresis in multilayer ceramic actuator by connecting the actuator with a capacitor in a series circuit. The change in hysteresis with respect to the capacitor was examined. 0.2Pb(Mg_(1/3)Nb_(2/3))O₃-0.8Pb(Zr_(0.475)Ti_(0.525)) O₃ ceramic material was used as a piezoelectric material for the actuator. Displacement of the actuator was measured in a capacitive gap sensor measuring system. In case of inserting a capacitor in a total circuit, hysteresis became dramatically decreased, and then finally the hysteresis value can be reduced below 0.2%. It was found in this present study that reducing the hysteresis in the actuator is dependent upon the characteristics of the capacitor in total circuit and also operating frequency

鄭淳宰,申允燮,具禹書 東亞大學校生命資源科學大學附設 農業資源硏究所 1992 農業生命資援硏究 Vol.1 No.1

臺木의 種類 및 오이品種의 溢泌現象 및 無機成分과 식물 hormone 含量에 關하여 硏究하엿던 바 그 主要結果는 다음과 같이 要約될 수 있다. 1. 溢泌液의 量 및 經時的인 變化를 보면 接木오이가 自根오이보다 顯著히 높아 臺木의 效果가 뚜렷하였으며 自根苗에서는 四葉오이가, 接木苗에서는 四葉오이를 黑種호박에 接木한 苗에서 增加되었다. 經時的인 變化는 接木, 自根 共히 最初의 1時間 採取時에 가장 많았고 時間이 經過함에 따라 低下하였다. 2 .溢泌液內의 無機物含量은 수세미와 黑種호박에서 K, Ca, Mg含量이 높았고 만춘청장마디오이와 四葉오이는 接木에 依해 K와 Ca의 含量이 增加되었으나, 溢泌液內의 無機物의 含量과 臺木의 生育促進效果와는 特定한 關係가 있다고는 判斷되지 않는다. 3. 溢泌液으로부터 Cytokinine과 Gibberellin을 抽出할 수 있었는데 Bioassays에 依해 檢出된 Gibberellin含量은 臺木의 接穗促進效果와도 關係가 있을 것으로 推定되었으나 Cytokinine含量에서는 特定한 傾向을 찾아볼 수 없었다 Studies were conducted to investigate the xylem sap exudation phenomena, mineral element contents and endogenous plant hormones in cucumber cultivars and different rootstocks. The major results can be summarized as follows. 1. The amount of xylem sap exudated from the basal cut stem were significantly influenced by cucumber cultivars and kind of rootstock. Among the tested cucumber cultivars, ‘Sayeup’ showed the largest amount of xylem sap. ‘Heukzong’ rootstock also showed the largest amount of xylem sap among the tested rootstocks. The amount of xylem sap exudation was largest in the first hour of cut and gradually decreased with time after cutting. 2. The contents of K, Ca and Mg were higher in the xylem sap of ‘Susemi’ and ‘Heukzong’ rootstocks contents of K and Ca in ‘Manchoon Chungjang-madi’ and ‘Sayeup’ Cucumber were also increased by grafting. The contents of mineral elements in xylem sap of rootstocks could not be correlated with the growth promotion effect of the rootstocks. 3. Contents of gibberellin-like substance in xylem sap of rootstocks seemed to have some relationship on its growth promotive effect of the scion by rootstocks. Cytokinins were also extracted but their role in scion growth is yet to be clarified.

Italian ryegrass(Lolium multiflorum Lam.) 분획 leaf protein을 neutral detergent 용액 처리에 의하여 NDF 잔사를 얻어, actinase 처리에 의하여 단백질을 제거하고, neutral detergent fiber 標品으로 하였다. 콜레스테롤 無添加 기초식이(casein 20% 함유)에 NDF를 2.0% 混合하여, 7주령이 Wister strain 흰쥐 숫컷에 14일간 급여하였다. 그 결과 혈청 총콜레스테롤 농도는 카제인 급여군과 NDF 첨가군 사이에는 차가 없고, 대두 단백질 급여군에 비교하여 유의하게 높고, NDF 添加에 의한 영향을 보이지 않았다. 한편, 농도는 카제인 급여군과 유의차는 없지만, NDF 첨가에 의하여 감소하는 영향이었다. Unfractionated leaf protein was prepared from Italian ryegrass (Lolium maltiflorum Lam.) by heating the green juice at 85℃. Wet leaf protein was extracted repeatedly with acetone followed by 80% ethanol to remove lipid, pigment and specifically saponin. The neutral detergent fiber (NDF) proposed by Van Soest have been widely accepted for the determination of plant food. In this study, the effect of NDF on the serum cholesterol level in rats fed with cholesterol free diet was examed. NDF were incoporated in the diet at a level of 2.0% without cholesterol free diet. This diet was fed for 14 days to male Wistar strain rats with body weight of 80 90g. It was found no significantly change in serum lipids level in the neutral detergent fiber fed rats in cholesterol free diet.

臺木의 種類 및 生長調節物質 處理가 여름삼척 仰制栽培 오이의 生育 및 收量에 미치는 影響 : Cucumis sativus cv. Summer Samchuk

鄭宰淳,李政明 경희대학교 부설 식량자원개발연구소 1986 硏究論文集 Vol.7 No.-

Studies were conducted to investigate the response of 'Summer Samchuk' cucumber grafted on different rootstocks and then treated with several growth regulators. The results are as follows. 1. Number of pistillate flowers was not significantly influenced by rootstocks even though 'Heukzong' rootstock tended to increase it. 2. Grafted cucumber seedlings were less responsive to GA_3 treatment as compared to intact seedlings. All the seedlings, however, showed similar response to ethephon treatment. 3. The growth of 'Summer Samchuk' cucumber was promoted by grafting to 'Heukzong' rootstock. Among the tested growth regulators, ethephon 250 ppm exhibited stronger inhibition of main stem growth. 4. Those plants grafted to 'Heukzong' rootstock showed higher fruit yield. The fruits tended to become shorter with grafting. Ethephon treatment reduced the fruit length and fruit diameter, thus resulting in inferior fruits.

鄭淳宰,具禹書 東亞大學校 1993 東亞論叢 Vol.30 No.1

오이는 性發現에 관한 基礎資料를 얻고져 飛節成種인 四葉과 節成種인 신록다다기, 그 中間形인 聖護院을 공사하여 種子와 崔芽종자의 蛋白質含量의 品種간 차이와 子葉展開期의 ethephon(250ppm)과 Gibberellin(100ppm)處理에 의한 蛋白質 含量과 peroxidase活性의 變化, 蛋白質 banding pattern 및 perosidase isoenzyme의 banding pteern의 變化 關係를 調査하여 다음과 같은 結果를 얻었다. 1) 種子와 崔牙種子인 蛋白質含量, 蛋白質 banding pattern 및 peroxidase의 banding pattern에서 飛節成과 節成品種간에 뚜렷한 차이를 볼 수 없었다. 2) 子葉期의 蛋白質 含量과 蛋白質 banding pattern에서는 3品種 모두 ethephon處理區에서 蛋白質含量이 높았고, 蛋白質 banding pattern에서는 處理 後 日數가 지남에 따라 變異를 보이다가 處理後 5日째 四葉의 ethephon 處理區의 Rf 0.33-0.34의 位置에 强度높은 band가 形成되었으며, 聖護院, 신록다다기의 無處理區에서 形成된 band의 位置와 强度가 同一하였다. 3) 子葉期의 peroxidase 活性 및 peroxidase banding pattern에서는 ethephon處理區에서 3品種 모두 peroxidase activity가 높게 나타났으며, ethephon 處理後 1일째는 3品種 모두 거의 같은 band의 樣相을 나타내었고, 處理 後 3일째는 變化의 樣相을 보이다가 處理後 5일째는 四葉의 ethephon 處理區와 聖護院, 신록다다기의 control區가 거의 같은 banding pattern을 나타내었다. This experiment was conducted to obtain the basic information the patterns of change in protein contents, peroxidase activity and of sex expression between three cucumber varieties(monoecious type;Sayeupl gynoecious type; Sinrokdadaki, intermediate type; Seonghowon) by treating ethephon with 250ppm and gibberellin with 100ppm at the maturing stage of their cotyledons. The patterns of changes in protein contents and peroxidase activity were analyzed using disk polyacrylamide gel electrophoresis and the results are summarized as follows. 1. No difference was found in changes of the protein contents, band pattern of peroxidase and iso peroxidase activities between mature seeds and germinating seeds of Sayeup(monoecious type) and Sinrokdadaki(gynoecious type). 2. High protein contents were obtained in cotyledons of all varieties treated with ethephon, and a variety of band patterns of protein isolated were shown on the gel during the initial stages after ethephon treatment. After 5 days of ethephon treatment, however, a strong band was observed at the Rf value of 0.33-0.34 on the gel analyzed from the proteins isolated from Sayeup cotyledons with etyephon treatment and the band intensity of their proteins was similar to ones from Seonghowonand Sinrokdadaki with no ethephon treatment. 3. As a result of gel analysis, high activity and strong band of peroxidase isolated from ethephon treated carieties was examined. Similar band patterns of proteins isolated were observed in the cotyledons of all carieties used after one day of ethephon treatment. After 3 days of ethephon treatment, all varieties showed various band patterns, while after 5 days, the band pattern of proteins isolated from ethephon treated Sayeup similar one of proteins from both Seonghowon and Sinrokdadaki with no ethephon.
