      • 菊花의 生長調整劑 處理에 관한 硏究

        鄭汶銖 진주산업대학교 농업기술연구소 1994 農業技術硏究所報 Vol.7 No.-

        난쟁이 菊花(福助菊)의 盆花生産 普及을 위한 豫備調査의 一環으로 藥劑效能 및 適正濃度를 찾기 위해 4種類의 菊花品種 각각에서 5個體에다 任意로 選定된 한 種類의 生長調整劑를 處理했다. 處理後, 1993年 7月 28日부터 11月 15日까지 植物의 크기, 잎의 數, 잎의 색깔, 頭狀花序의 直徑 및 높이의 變化가 測定記錄되어졌다. 얻어진 資料를 統計處理한 結果는 다음과 같다. 1. 無處理로 키운 4種類의 菊花品種중 '국화태양'이 길이가 가장 컸을 뿐 아니라 頭狀花序의 直徑도 가장 높았다. 2. 40,000ppm 및 20,000ppm의 Fatty alcohol로 處理된 'Pink동아'는 處理直後 곧 바로 藥害(組織破壞)로 枯死했으나, 나머지 濃度(10,000ppm, 無處理)로 處理된 'Pink동아'는 生長해서 꽃을 피웠다. 3. SADH로 處理된 '금봉관'의 크기는 無處理와 比較할 때 統計學的으로 重要하게 差異 났으나(P<0.05), 濃度別로는 差異가 나지 않았다(P≥0.05). 反面에 잎의 數는 각각 濃度別間 및 無處理와 間에 統計學的으로 아무런 差異가 없었다(P≥0.05). 頭狀花序의 直徑은 8,000ppm으로 處理된 5個體들이 다른 處理 및 無處理보다 가장 작았다(8.36±5.34cm, P<0.05). 4. Paclobutrazol로 處理된 '대훈위'는 頭狀花序의 直徑을 除外하고는 植物의 크기, 잎의 數 및 頭狀花序의 높이는 각각 濃度別間 및 無處理間에 統計學的으로 重要하게 差異가 나지 않았다(P≥0.05). 5. Uniconazole 10% WP로 處理된 '국화태양'은 잎의 數를 除外하고는 나머지 3가지 形質에서 각각 濃度處理別間 및 無處理間에 統計學的으로 重要하게 差異가 나지 않았다(P≥0.05). 濃度別 處理된 個體에서 잎의 數는 100ppm과 25ppm의 Uniconazole로 處理된 個體들 사이에는 重要하게 差異가 났다(그들 각각의 平均 값은 7.66±3.93個 및 10.38±5.94個였다). 6. Fatty alcohol로 處理된 'Pink동아'品種 중 죽지않고 繼續 生長을 했던 1,000ppm 濃度로 處理된 個體 및 無處理된 個體들 間에는 頭狀花序의 높이를 除外한 다른 3가지 形質은 두 處理間에 重要하게 差異가 났다(P<0.05). As a part of investigation for producing and propagating dwarf chrysanthemums, each five individuals from four different chrysanthemums cultivars ('Kumbongkwan', 'Daehunwhi', 'Kukwhataeyang', and 'Pink-Dong-A') were separately treated by one growth regulator with three different concentrations selected from commercially available four different growth regulators (SADH, Paclobutrazol[PP 333], Uniconazole 10% WP, and fatty alcohol) to find the effects of the regulator and an optimal concentration. After treatments, changes in plant height, number of leaves, color of leaves, diameter of head, and height of head were measured and recorded from 28 July to 15 November 1993. 1. Among the four untreated cultivars, the mean plant height and the mean diameter of head of 'Kukwhataeyang' were the highest. 2. 'Pink-Dong-A' treated by 40,000ppm and 20,000ppm fatty alcohol immediately died owing to the damage from the regulator. 3. The mean plant height of 'Kumbongkwan' theated by the SADH was significantly different from that of the untreated individuals (P<0.05). On the other hand, the mean number of leaves was not significantly different between the treated individuals and the untreated individuals (P≥0.05). The smallest mean diameter of head was observed in five individuals treated by the SADH with 8,000ppm concentration(8.36±5.34cm, P<0.05). 4. Except the mean diameter of head, the mean plant height, the mean number of leaves, and the mean height of head of "Dehunwhi' treated by the paclobutrazol was found to be not significantly different between the treated individuals and the untreated individuals(P≥0.05). 5. Except the mean number of leaves, no statistical difference (P≥0.05) was found among the three treated individuals and between the treated individuals and the untreated individuals in the mean plant height and the mean diameter and the mean height of head of 'Kukwhataeyang' treated by the Uniconazole 10% WP. On the other hand, the mean number of leaves treated by 100ppm was significantly different from that of the five individuals treated by 25ppm (P<0.05), with their means of 7.66±3.93 and 10.38±5.94, respectively. 6. Except the mean height of head, the means of other three characters of 'Pink-Dong-A' treated by 10,000ppm were found to be significantly different from those of the five untreated individuals (P<0.05).

        8-9세기 해로의 활성화와 지중해 해상교역

        정문수 한국항해항만학회 2002 한국항해항만학회지 Vol.26 No.3

        The Sea road which is connected from the Gulf of Persia to Canton was completed by Arabs in the end of the eighth century. For the first time in history, the amount of goods by the sea route exceeds land route. In contrast with the Mediterranean, the Indian Ocean was a sea of peace. Its western shores were under Muslim control, thus we find in this age a great expansion of commerce on the Indian Ocean. We trace the sea route to China in use in the middle of the ninth century. Also we find out that the outstanding feature of the medieval Arab ship of Indian Oceans are two the manner in which planks of the hull sewn together, not nailed; and the fore-and-aft set of the sails. 8-9세기는 무슬림 상인의 주도로 페르시아만에서 남중국까지의 해로가 활성화되는 시기이다. 동서교류에서 해로가 육로를 능가하는 이 시기에는, 이 간선 해로를 따라 그 동단인 동아시아해역과 그 서단인 지중해 해역이 설정되었다. 먼저 간선 해로에 관해, 기존 연구에서 미진하게 검토한 페르시아만에서 인도 동쪽 바다까지의 왕복 항로와 아랍선박을 검토하였으며 심해항행이 진행되었다는 것을 지적하였다. 다음으로 이 시기에 동아시아해역의 해상무역이 장보고의 활약으로 활성화되었던 것과는 달리, 지중해 해역은 로마제국 시대의 활기를 잃고 상대적으로 위축되어 있다는 것을 지적하였다.

      • 개정 로마자 표기법의 문제점과 그 개선방안

        정문수 大田大學校 1984 論文集 Vol.3 No.1

        The Ministry of Education(MOE) revised the romanization system for korean and publicized the new system in January, 1984. According to the authorities concerned, the revision was carried out to settle the present chaotic state of korean romanization and accomplish its unification. However it is quite dubious whether the revised system could achieve such a purpose, for it is nearly the same as the so-called MR system which has been criticized to have no less shortcomings than the previous MOE system. The purpose of this paper is to appraise the revised system and make some suggestions for its betterment. In my opinion the revised system has more disadvantages over the previous system. The first and foremost fault results from its indiscriminate introduction of diacritic marks such as breve and apostrophe. Since they are quite unfamiliar to the general public, we cannot expect any effect of their use. And that there is even the possibility of misleading because the convention for them is quite different from that of IPA or general phonetics. Moreover they cause many inconveniences and difficulties in typing and writing. Owing to the defects just mentioned, breve and apostrophe are allowed to be omitted in the revised system. Here arises another problem:impossibility of distinguishing the phonemes. As breve is omitted,「ㅓ」and 「ㅡ」cannot be distinguished from「ㅗ」and「ㅜ」 respectively. cannot be distinctive from「ㅍ,ㅌ,ㅊ,ㅋ」respectively in the word initial position because of the omission of apostrophe. That will cause many difficulties in communication and connot be justified, for romanization is in essence a kind of tools for communication. Another defect of the revised system is its inconsistency in the representation of vowels. To say more concretely「ㅓ」and「ㅡ」are written by use of breve, but「ㅐ」and「ㅚ」by use of diagraphs, even though the four vowels share the same character that they lack their counterparts in the system of Roman letters. The assignment of two letters「s」and「sh」for one phoneme is not so desirable, either. That must be an unnecessary complication because〔∫i〕(induced by「shi」is not much, closer to〔? i〕(actual pronunciation) than〔 si〕(induced by「si」). However it can be estimated as the merit of the revised system to adopt the principle of transcription, discarding that of transliteration adopted in the previous system. The reason is that the former principle is more advantageous to the realization of actual pronunciation and that is more consistent with practical purposes of romanization. Therefore, considering the above-mentioned merit and faults of the revised system, I propose my alternatives as follows. 1. I favor for the principle of transcription. Therefore morphophonemic changes such as consonant assimilation and palatalization are reflected in the representation. 2. As for the assignment of letters for vowels, I propose one of the following two alternatives. 1) If the introduction of diacritic marks is inevitable, I propose to use umulaut rather than breve, for the former is much easier to type and write and more familiar to the general public than the latter. In that case the problematic vowels can be written like (6) (in the body of this paper). 2) If we use no symbols other than Roman letters, the use of diagraphs is the only way to represent the vowels in question. In this respect the previous MOE system is not so blameworthy. However, considering the fact that blames for the previous system were focused on the representation of「ㅓ」and「ㅡ」, I propose to rewrite those vowels like(8) (in the body of this paper). 3. Three serials of korean plosives must be distinguished from one another in word initial position. Therefore I propose that they should be distinctive like (9) in those positions. However they need not be distinguished in word-final position or before voiceless cosonants since they are neutralized in those environments.
