      • Korean Dictionaries and Some Model Dictionaries of the World : Critical Essays toward the Plan for a New Korean Dictionary

        Lee, Sang Sup,Nam, Ki Shim,Ahn, Sam Huan,Choi, Young Ai,Hong, Chai Song 연세대학교 언어정보개발원 1988 사전편찬학 연구 Vol.1 No.1

        After briefly reviewing the history of lexcoigraphy in modem Korea, Nam Kishim tackles many problems created by the general deficiency of current Korean monolingual dictionaries in phonological morphological and semantic points. For example, most Korean dictionaries do not treat such phonological changes as the shortening of the stem vowel ㅓ in 더운, the prenominal form of the adjective 덥다, whose stem vowel ㅓ is pronounced long. He also takes issue with the practice of Korean dictionaries of including all kinds of proper names on little reliable principles : a typical dictionary enters a 600m-high hill while excluding better-known mountains higher than that. Hong Chai-song concentrates on the often misguiding information on transitive / intransitive verbs in current dictionaries. For example, a representative dictionary designates the verb 뛰다 simply as intransitive. But it is quite often used as an transitive also. In the sentence, 철수는 운동장을 뛰었다, 운동장 is the object of the transitive verb 뛰다. How could the compilers miss such an obvious fact? Hong suggests that they may have not been interested in being grammatically informative. A historical survey of the Oxford English Dictionary(OED) is given by Lee Sang-sup, with special emphasis on the vast amount of quotations from real sources contributed by thousands of volunteer readers through several decades and on its unwavering historical principle. A comparison between the OED's definition of Kimchi and a Korean dictionary's 김치 is given, showing the difference of principle in treating the same lexical item. Ahn Sam-huan presents a detailed account of Grimm's Deutsches Wo¨rterbuch which took generations of German lexicographers 133 years from its inception to its completion in 1971. On the basis of his study, Ahn suggests that future dictionary makers should cooperate as a group on a long-range comprehensive project. A moltivolume dictionary is an all-important cultural event for the whole nation, not to be influenced by private commercial interests. Choi Young-ai's survey of Chinese lexicography highlights the now on-going publication of 漢語字典 and 漢語詞典, admirable results of the cooperative effort of hundreds of Chinese scholars, a modus operandi for the Yonsei University graze to adopt in planning a new dictionary of the Korean language.

      • 水稻 直播栽培에 關한 硏究 : (Ⅰ)栽培方法이 節間長에 미치는 影響

        趙東三,許華永,朴成圭,尹洪載,金泰秀 충북대학교 농업과학기술연구소 1989 農業科學硏究 Vol.7 No.2

        Data on internode length obtained from cultural experiments on seeding date, seeding method and seeding rate in direct seeding cultivation of rice in 1989 were analyzed to investigate the rela-tionship between internode length and lodging. In general, internode length appeared to be longer in earlier plantings except May 11 planting which had longer internode than those of other plantings. Seeding in flooded condition as well as higher seeding rate resulted in longer internode length. Culm diameter leas greater in the order of April 21 > May 11 > May 21 > May 1 plantings, and drilled in upland condition > broadcasting in upland condition > seeding in flooded condition, while the higher the seeding rate, the greater the culm diameter was. Except seeding in upland condition and seething rate of 3kg/10a which showed lodging degree of 1, all other treatments resulted in severe lodging with degree of 7.

      • 肥育牛의 濃厚飼料에 對한 香味素의 添加가 飼料의 攝取量, 增體量 및 飼料利用率에 미치는 效果

        朴弘錫,許三男,崔亨松 全北大學校 附設 畜産開發硏究所 1987 畜産開發硏究報告 Vol.1 No.-

        To investigate the effect of supplementing feed flavor in the beef rations containing urea on concentrate consumption, body weight gain and the efficiency of concentrate utilization two feeding experiments were conducted. Ten Holstein steers weighing 230-250㎏ were divided into groups and fed the control and the urea containing ration in the first trial for 50 days, then the feed flavor supplementing trial was followed for 136 days. Using urea at the level of 1.6% significantly(P<0.05) decreased both concentrate intake(5.37 vs 5.02㎏/day) and body weight gain(1.05 vs 0.93㎏/day). When the feed flaver (Aromastat for 61 days and followed by Beef-Feednectar for 75 days) was supplemented, it significantly(P<0.05) increased both the concentrate intake(7.90 vs 8.54㎏/day) and body weight gain(1.35 vs 1.47㎏/day). The efficiency of concentrate utilization was also improved but it was not statistically significant. Based on the results of the feeding trial, it is concluded that supplementing feed flavor in the ration containing urea improves feed consumption and growth of beef cattle.

      • 방선균 J-144K가 생산하는 Adenosine Deaminase Inhibitor에 관한 연구

        전홍기,김상웅,조영배,이인 부산대학교 유전공학연구소 1996 분자생물학 연구보 Vol.12 No.-

        Adenosine deaminase의 새로운 저해제를 검색하기 위해 토양으로부터 adenosine deaminase 저해제를 생산하는 8균주의 방선균을 분리하였으며, 그중에서 저해활성이 가장 우수한 J-144K균주를 공시균주로 선정하였다. Adenosine deaminase 저해제 생산을 위한 최적배지 조성은 1.0% dextrose, 0.5% yeast extract, 0.5% peptone, 0.1% KH_2PO_4이었으며, 초적온도와 pH는 각각 30˚C와 7.0이었다. 이러한 조건에서 500ml용 진탕플라스크에 최적배지 100ml를 넣어 배양했을 경우 정지기인 배양 60시간째에 adenosine deaminade 저해활성이 가장 높게 나타났다. 분리균주 J-144K의 배양상등액으로부터 활성탄 흡착 및 유기용매 추출, Dowex 50 H^+ X-8 column chromatography, Dowex 1 Cl^- X-8 column chromatography, Sephadex G-15 gel filtration 등의 과정을 거쳐 adenosine deaminase 저해제를 정제한 결과, 3가지 종류의 저해제가 존재함을 알 수 있었다. In the screening of actinomycetes' culture filtrate for inhibitor of adenosine deaminase, a novel inhibitor was found in a cultured broth of strain J-144K. The optimum conditions for the adenosine deaminase inhibitor production from the isolated strain J-144K were evaluated. This strain showed the maximum yield of adenosine deaminase inhibitor when grown at pH 7.0 and 30˚C for 60 hours in the medium of 1.0% dextrose, 0.5% yeast extract, 0.5% peptone and 0.1 % KH_2PO_4 under the aerobic condition. Through the activated charcoal extraction, methanol fractionation, Dowex 50 H^+X-8 ion exchange column chromatography, Dowex Cl^- X-8 ion exchange column chromatography, and Sephadex G-15 gel filtration procedures, this inhibitor was purified with three materials.

      • Calcium Hydroxide 처리가 양앵두 果實의 品質에 미치는 영향

        정삼택,김유신,전상항,김익홍 경북대학교 1990 새마을 硏究論叢 Vol.11 No.-

        양앵두 佐藤錦 및 Napoleon品種을 供試하여 Ca(OH)_2 處理濃度 및 處理回數에 따른 果實生長, 果實品質, 칼슘축적 및 裂果에 미치는 影響을 調査하였던바 다음과 같은 結果를 얻었다. 1. 양앵두 果實生長은 佐藤錦품종에서 收穫1週前 Ca(OH)_2 처리농도간에는 차이가 없었으나, Napoleon품종에서 Ca(OH)_2 처리회수가 증가 할수록 抑制되었다. 2. 可溶性 固形物과 Anthocyanin함량은 Ca(OH)_2 처리농도 및 처리회수를 증가 할수록 감소하였으나, 유기산 함량은 증가하였다. 3. 果實內 칼슘축적은 Ca(OH)_2 처리농도 및 처리회수가 증가 할수록 증가하였고, 佐藤錦 품종에서 과실내 칼슘함량은 과피, 종자, 과육, 핵의 순이였고, Napoleon품종에서는 종자, 과피, 과육, 핵의 순이였다. 4. 裂果방지를 위한 Ca(OH)_2 처리는 7.2g/l를 수확 3주전부터 1週間隔으로 3회 살포하는 것이 열과를 감소시키는데 효과적이였다. The study was conducted to investigate the influences of several concentrations of Ca(OH)_2 and application time on fruit growth, quality, contents of Ca in fruits and cracking of 'sa Tou Nisiki' and 'Napoleon' sweet cherry. The results obtained are summarized as follows; 1. In Ca(OH)_2 treatments, the fruit growth of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry was not influenced by its concentrations but by application times of Ca(OH)_2. 2. Contents of soluble solids and anthocyanin according to concentreation and application of Ca(OH)_2 were decreased, while titratable acidity was increased respectively. 3. Contents of Ca in the fruit according to concentration and application of Ca(OH)_2 were increased and Ca contents in both fruits differ from fruit portions. 4. Preharvest application of Ca(OH)_2 by 0.72% and three times applications reduced cracking of 'Sa Tou Nisiki' and 'Napoleon' sweet cherry. From these results, twice applications of Ca(OH)_2 to the sweet cherry are recommended for the best fruit quality, the authors believed.
