林海鎭,黃盛晧 三陟大學校 1998 論文集 Vol.31 No.1

In parallel with rapid advances and increased reliance on telecommunication services, network technologies continue to evolve. In addition, the advanced switching technologies required for ATM technology and switched multimegabit digital service(SMDS) are now being deployed. Considering the rapid deployment of new services and technologies, escalating competive pressures, and the broadening demands of customers, service providers face an immediate and pressing need to streamline, simplify, and automate network management operations. This research provides the first step in the requirements process for a new type o network operations capability. The logical model of this research describes a set of functions that could be assigned to either physical standalone components, operations systems, or network elements. This research should help facilitate consistency in the way the operations for different new technologies are specified.

導入育種의 一環으로 中國産 마늘 가운데서 球의 形質로 보아 優秀하다고 認定되는 上海種과 瀋陽種을 우리나라 代表品種인 義城種(寒地型) 및 濟州種(暖地型)과 함께 溫室과 圃場栽培 實驗으로 이들의 性能을 檢討한 결과를 要約하면 다음과 같다. 1) 上海, 瀋陽 및 濟州種은 無低溫區와 2∼3℃의 20日, 40日 및 60日間 低溫處理區에서 모두 播種後 約 1週日이 經過한 10月 20日 頃부터 萌芽하기 始作하였다. 萌芽期間은 上海種이 19∼22日, 그리고 濟州種이 17∼26日로서 低溫處理期間이 延長됨에 따라 短縮되었으나 瀋陽種은 低溫處理 與否에 關係없이 9∼12日 所要되었다. 2) 寒地型인 義城種은 無低溫區에서 播種後 74日이 經過한 12月 27日에 萌芽하기 始作하였으며, 低溫處理期間이 延長됨에 따라 漸次 빨라져서 60日間 處理區에서는 播種後 13日이 經過한 10月 26日에 萌芽가 始作되었다. 그리고 萌芽期間이 延長됨에 따라 顯著히 短縮되었다. 따라서 上海種과 瀋陽種은 暖地型이라고 認定되었다. 3) 圃場栽培에서 瀋陽種이 다른 品種에 比하여 根重, 球重 및 球當鱗片種이 가장 무거웠고, 球當鱗片數가 많았으며 또한 球高, 球徑 및 莖徑이 커서 品種間 差異가 있었으나 莖徑/球徑比는 供試 4品種 모두 0.2였다. 4) 上海種은 草長, 莖長 및 花梗長이 매우 짧으며 珠芽重은 0.3g로서 가장 가볍고 葉數가 많으며 葉幅이 컸다. 또한 暖地型인 上海, 瀋陽 및 濟州種의 추대기는 5月 12日로서 추대율은 100%였으나 寒地型인 義城種의 추대기는 6月 8日로서 추대율은 30%였다. 5) 供試 4品種의 植物全體의 乾物重은 播種後 135日 經過한 4月 7日부터, 그리고 球의 乾物重은 播種後 149日이 經過한 4月 21日부터 急激히 增加하였는데 이들中 瀋陽種이 가장 旺盛한 增加를 보였고 그 다음이 上海種이였다. 6) 供試 4品種의 줄기의 乾物重은 播種後 135日이 經過한 4월 7日부터 急激히 增加하였는데 이들중 上海種이 가장 旺盛하게 增加하였고 그 다음이 瀋陽種이였다. 그리고 잎의 乾物重은 緩慢하게 增加하였으나 瀋陽種이 가장 무거웠다. 葉面積은 瀋陽種이 가장 넓으며, 早期에 增加하기 始作하고 그 速度도 빨랐다. 7) 暖地型인 瀋陽種은 上海와 濟州種보다 早生으로서 生育이 旺盛하여 球重이 무겁고 燁數가 많으며 葉面積이 넓어서 우리나라 濟州道와 南海岸地帶에서 普通栽培와 冬季施設栽培에 利用할 수 있으리라고 믿어졌다. As a part of introduction breeding, two Chinese garlic cultivars, Shanghai and Shenyang, were cultivated in greenhouse and in field with two typical Korean cultivars, Euisung and Cheju, southern and northern ecotype respectively, and the characters and growth characteristics were investigated. 1. Shanghai, Shenyang and Cheju cultivars treated with low temperature of 2 ~ 3℃ for 20, 40 and 60 days and also the nontreated ones began to sprout from Oct. 20, about one week after planting. Sprouting periods were 19 ~ 22 and 17 ~ 26 days in Shanghai and Cheju cultivar, respectively. These periods were shortened as the low temperature treating periods were extended, but Shanghai cultivar needed 9 ~ 12 days for sprouting regardless of low temperature treatment. 2. A northern ecotype, Euisung cultivar, began to sprout on Dec. 27, 74 days after planting in period was extended, for 20 ~ 66 days, and began to sprout Oct.26, 13 days after planting. From this result, Shanghai and Shenyang cultivars were recognized as a southern ecotypes. 3. In field cultivation, root weight, bulb weight and clove weight per bulb were superior in Shenyang among all the four cultivars and had many cloves per bulb and also showed superior bulb height and blub diameter. These characters represented differences among cultivars, but the ratio of stem diameter to bulb diameter was 0.2 in all four cultivars. 4. Heights of plant, stem and flower stalk were the longest and the bulblet weight, 7.0g, were the heaviest in Shanghai cultivar. In Shenyang cultivar, the flower stalk was very short and the bulblet weight was light, 0.3g, but had many leaves and showed wide leaf width Shanghai, Shenyang and Cheju cultivars, southern ecotype ones, bolted on May 12 and the bolting ration was 100%, but Euisung cultivar, nothern ecotype, bolted on Jun. 8 and the bolting ra-tio was 30%. 5. Dry weight of whole plant and the bulb increased markedly from Apr. 7, 135 days after planting, and from Apr. 21, 149 days after planting, respectively, in all four cultivars, and Shenyang showed the most vigorous increment and Shanghai was next. 6. Stem dry weight increased markedly from Apr. 7, 135 days after planting in all four cultivars; and Shanghai showed the most vigorous increment and Shanghai was next. Leaf dry weight increased gradually and that of Shenyang were the heaviest one. Leaf area of Shenyang cultivar was most broad and grew early and rapidly. 7. Shenyang cultivar, a southern ecotype, grew earlier as compared with Shanghai and Cheju cultivars, and grew vigorously, and the bulb weight was heavy and had many broad leaves. It was considered that these two Chinese cultivars are possible to cultivate in Cheju and south coast districts of the Korean Peninsula by common method and in greenhouse during winter season.

This study was carried out to obtain the basic informations of a selection of superior geo-eco-type and breeding. The results in this study obtained were summarized as follows : 1. A basic number of chromosome of Allium grayi is x=8. Out of 18 localities of Allium grayi in this experiment examined, 15 localities have tetraploid, 3 localities have pentaploid, and diploid was not founded. 2. This result indicated that tetraploid and pentaploid plants are mixed in the same localization. It was supposed that it was distributed sporadically according to growth environment in each localization. 3. Karyotypes of tetraploid and pentaploid consisted of metacentric, submetacentric and subterminal chromosomes. They were investigated rarely satellite in sumbetacentric chromosome. Karyotypes of tetraploid were divided into three different types as 20V + 12J, 23V+V^t+8J and 24V+8J. Karyotypes of pentaploid were divided into two different types as 25V+15J and 30V+10J. 4. Out of 18 collected varieties, the length of the longest chromosomes were revealed 11.76 (Bonghwa)∼23.47㎛(Yungil), and the length of the shortest chromosomes were 4.24(Yungyang)∼8.53㎛(Jumchon). The collected varieties from Yungil, Yungyang, Ulleung and Yungduk have a long chromosome(〉19.00㎛) that has not detected other varieties.

The purpose of this study is to establish a production system for providing fresh leafy garlic in winter season and to obtain data for an easy method of indoor nutriculture of this plant, especially in apartment life. 1. Emergence rates in 15℃ and in 20℃ cultured by Hyponex and by tap water were 100% after 7 and 21 days from planting in Shenyang cultivar, a Southern ecotype, and in Cheju cultivar, a Southern ecotype respectively. Euisung cultivar, a northen ecotype, did not planting uner 15℃ until 7 days from planting, but emerged 85% and 95% after 21 days from planting under 15℃ and 20℃ conditions, respectively. 2. Plant lengths were higher in 20℃ and in Hyponex culture than in 15℃ and in tap water culture, respectively. Shenyang cultivar in 15℃ and 20℃ cultured by Hyponex and tap water ceased to eloongate the leaf and showed chlorosis after 35 days from planting, but Cheju and Euisung cultivars continued to elongate the leaf. The plant length of Shenyang cultivar was especially long as compared with other two cultivars and grew fast. 3. After 21 days from planting, leaf number, diameter of leaf sheath, leaf weight and weight of leaf sheath were higher in 20℃ and in Hyponex culture than in 15℃ and in tap water culture. respecively. Among three cultivars, Shenyang had much more leaves and heavy ones. 4. Comparative crop growth rate(CGR) showed at maximum after 7 days from planting in 15℃ and in 20℃ cultured by Hyponex and by tap water in Shenyang and Cheju cul-tivar while after 14 days from plamting in Euisung cultivar, then decreased gradually afterward. The CGR at maximum was higher in 20℃ and in Hyponex culture than in 15℃ and in tap water cul-ture, respectively. 5. The percentage of contribution of CGR to leaf were increased until 21 days from planting, then decreased gradually afterward in Shenyang and Cheju cultivars, but Euisung showed continu-ous increase. The percentage of contribution of CGR to root declined markedly after 14 days from planting in all three cultivars. 6. Leaf area index(LAI) were high in all three cultivars in 20℃ in Hyponex culture as compared with tap water culture. After 28 days from planting, LAI was 2.0 and 1.0 in Cheju and in Euisung cultivar respectively, comparing with above 4.0 in Shenyang cultivar. 7. In every conditions, Shenyang cultivar exceeded in emerging date, plant length and leaf produc-tion, and the growth was better in 20℃ and in Hyponex culture than in 15℃ and in tap water cul-ture, respectively. After 14 days from planting, Shenyang cultivar was possible to harvest in 20℃ cultured by Hyponex and by tap water.

近來 中國으로 부터 導入한 마늘을 種球로 使用한 農家가 잘못된 品種選擇으로 被害를 본 事例가 있어 中國産마늘의 生育特性과 核型을 檢討하여 裁培와 育種에 필요한 資料를 얻고자 하였다. 1)寒地型인 義城種은 無低溫處理區에서 萌芽開始日이 12月 27日이고 萌芽期間은 66日이 所要되었으나 低溫處理區에서는 處理期間이 길어짐에 따라 漸次 萌芽開始日은 빨라지고 萌芽期間은 短縮되어 가장 긴 60日間의 低溫處理區에서 萌芽開始日이 10月 26日이였고 萌芽期間은 20日이었다. 2)그러나 上海種은 無低溫處理區와 各低溫處理區에서 모두 萌芽開始日이 10月20日~22日이고 萌芽期間은 19~22日,그리고 瀋陽種은 萌芽開始日이 10月 20日이고 萌芽期間은 9~12日로서 低溫處理로 因한 萌芽促進效果는 거의 認定할수 없었다. 뿐만아니라 上海種과 瀋陽種의 無低溫處理區의 萌芽開始日은 義城種의 60日間 低溫處理區의 萌芽開始日보다 빠름을 볼때 이들 導入種은 低溫에 매우 敏感한 暖地型이라고 判斷되었다. 3)上海種과 瀋陽種의 植物全體의 乾物重은 播種後 135日이 經過한 4月7日부터,그리고 球의 乾物重은 播種後 149日 經過한 4月21日 부터 급격히 增加하였으나 잎,뿌리 및 줄기의 乾物重은 始終 緩慢하게 增加하였다. 4)上海種과 瀋陽種는 播種後 149日 經過한 4月21日에 綠葉面積의 極大期를 이루었는데 이 時期는 球乾物重의 急激한 增加期와 一致하였다. 5)供試 3品種의 核型은 中部,次中部 및 次端部染色體로 이루어져 있고 附隨體는 볼수 없었다.이들의 核型은 上海種이 K(2n)=12V+4J로 2차狹窄을 볼 수 없었고,瀋陽種은 K(2n)=10V+4J+2Jcs 그리고 義城種은 K(2n)=10V+2Vcs+4J로서 各各 2個의 染色體에서 2次狹窄을 볼수 있었다. 6)染色體의 길이와 長腕에 對한 短腕의 比率은 上海種이 15.00~8.46㎛와 1.00~0.32,瀋陽種이 16.93~8.84㎛와 0.91~0.39그리고 義城種이 21.54~7.31㎛와 1.06~0.58로서 品種間 差異가 있었다. This study was carried out to obtain the basic data for culture and breeding of introduced garlic cultivars. The results obtained in this study were as follows : 1) In northern ecotype cultivar 'Euisung', first sprouting was observed on Dec. 27 and the period required for sprouting was 66 days after sowing. Extended treatment with low temperature has shown to be effective both in advancing the sprouting date and shortening the sprouting period. 2) In cultivars 'Shanghai' and 'Shenyang', first sprouting were observed on Oct. 20∼22, and Oct. 20, respectively, and the period required for sprouting was 19∼22, and 9∼12 days, after sowing respectively. Low temperature treatment was not effective to both cultivars. This result indicated that these two cultivars are southern ecotype which is sensitive to low temperature. 3) Whole plant and bulb dry weights of cultivars 'Shanghai' and Shenyang' increased remarkably 135 days (April 7) and 149 days(April 21) after sowing, respectively. In constrast, leaf, stem and root dry weights increased gradually. 4) When green leaf area reached to a maximum level at 149 days after sowing(April 21), bulb dry weight began to increase remarkably in cultivars 'Shanghai' and 'Shenyang'. 5) Karyotype analysis of three cultivars revealed that they consist of metacentric, submetacentric and subterminal chromosomes. Karyotype of cultivars 'Shanghai', 'Shenyang' and 'Euisung' were K(2n)=12V+4J, 10V+4J+2J^cs and 10V+2V^cs+4J, respectively. Karyotypes of cultivars 'Shenyang' and 'Euisung' showed they have two secondary constrictions, but did not have satellite type. 6) Chromosome length and a ratio of short arm and long arm were 15.00∼8.46㎛ and 1.00∼0.32 in cultivar 'Shangai' 16.93∼8.84㎛ and 0.91∼0.39 in cultivar 'Shenyan', and 21.54∼7.31㎛ and 1.06∼0.58 in cultivar 'Euisung'.

We characterized 48 soils of seed farms originated from Korea, China, America, Australia, and Italy. Physicochemical characteristics of soils are summarized as below. Loam and sandy soil are distributed to the seed farms of Korea, China, and Australia. Moderately, fine soil is distributed to the seed farms of America and Italy. The content of organic matter of seed farms are shown in the value of 2.0±0.6% (Korea), 4.1±2.1% (Australia), and 3.2±1.2% (America), respectively. Taken together, the content of Korea is lower than that of foreign countries. Available phosphous (P₂O5) is shown in the value of 229±106~ 462±225ppm in the seed farms of Korea, China, and America. But Australia and Italy showed the average value of 77ppm. All areas investigated in this study are contained a high content of exchangable cation (K+, Ca++, and Mg++). Especially, the content of Ca++ is very high in the seed farm of Italy than that of other countries. Degree of base saturation in soil of Korea (71.2±14.9%) is lower than that of foreign countries (83.3±11.0~99.0±0.2%). The content of available boron is very low in Korea (average 0.39±0.22ppm) as compared to America, Australia, and Italy.
