Lee,Jun-Ki,Hyun,Sang-Ki,Lee,Sang-Sun,Chai,Jung-Ki 한국자원식물학회 2002 Plant Resources Vol.5 No.1

Twenty-three plants of Japanese apricot (Prunus mume) were collected from several sites around Mountains JIRI in Korea. Japanese apricots having the different morphological features were evenly distributed in the groups made from the cluster analysis, indicating no geographic distributions but artificial vegetations in Korea. Japanese apricots were, as based on the PCR-RAPD techniques, clustered into the three groups; a group (prototype) having the five white petals with the five red sepals, a group (green type) having the five white petals with the five green sepals, and a group (hybrid type) having the more than five red petals with various colored sepals. The prototype apricots showed higher toxicities than other type apricot against bacteria and production of less compounds in TLC plates. The polypetal types of Japanes apricot were related to those of p. armebiaca in the characteristics of seed (the ruggedness), but also to be closed to those of p. armebiaca in PCR-RAPD analysis. The cluster analysis of the twenty three apricots and its related species calculated from the two primers were shown to distinguish relationships of cultivars within species, or of individual plants within cultivars, but also to display the two overlapping bands resulted from PCR-RAPD technique.

슬러지 재자원화에 관한 연구

이 연구는 1993년도에 우리나라의 연간 슬러지발생량이 약 3500만m³에 이르고 있으며, 이들 대부분이 매립되고 있다. 그러나 매립부지의 확보가 점점 어려워 지고 있으며 아울러 매립처분비용도 상승하고 있기 때문에 oil화, 퇴비화등으로 재자원화 하는 방법과 소각후의 소각회를 유효이용하는 방법 등이 연구 개발되고 실용화되고 있다. 슬러지의 oil화는 현재 연구단계에 있으나 앞으로 슬러지의 유효이용기술로서, 가장 좋은 방법이 되리라 기대되고 있다. 그러나 소각후의 소각회의 이용방법은 현재 일본등에서는 실용화 되어 건설자재 등으로 다양하게 이용하고 있다. 우리나라에서도 서울시 등을 비롯한 대도시에서는 하수처리장에서 발생하는 슬러지를 소각한 후에 소각회를 건설 자제용으로서 지자체의 공사에는 반드시 사용하도록 하는 제도를 만든다면 유효이용방법으로 충분한 타당성이 있을 것이다. 이때 소각방법으로는 용융소각방법이 보다 효과적일 것이다. With increasing sewage and wastewater sludge, it has become difficult to dispose the sludge by landfilling and ocean dumping. To solve this problem, efforts have been made to delelop sewage and wastewater sludge utilization technologies in many advanced countries. Some technologies have already been developed; conversion of sludge to compost and fuel, producing artificial light-weight aggregate from ashes. This paper describes the technical status of sludge utilization technologies.

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.

수입각증후군에 의한 급성 복증 1례

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

2-Azetidinone 유도체의 합성

이채호,조성동,이만구 圓光大學校 基礎自然科學硏究所 1987 基礎科學硏究誌 Vol.6 No.1

Synthesis of N-benzyl-2-azetidinone derivatives from αmethyl and a-benzyl N-benzylasparate is described. a-Methyl and a-benzyl N-benzylasparate were cyclized to 1-benzyl-4-methoxycarbonyl-2-azetidinone and 1-benzyl-4-benzyloxycarbonyl-2-azetidinone by employing phase transfer catalyst. The substitutents of the resulting monocyclic β-lactams were converted to hydroxymethyl, methoxymethyl and mesyloxymethyl groups.

Praziquantel(Cestocide^ⓡ), Korean product, was tested for its efficacy in the treatment of Taenia saginata and Diphylobothrium latum infection during the period from May 1983 to October 1985, A total of 30 patients were treated with 10~30㎎/㎏ single dose of praziquantel and purged with 20~30g of magnesium sulfate to recover the worms. The results were as follows: 1. The patients were 26 cases of T. saginata and 4 cases of D. latum and after the treatment all of them discharged tapeworm segments with or without their scolices. The scolex recovery rate was 43.3%(from 11 and 2 cases of T. saginata and D. Iatum respectively). 2. The follow[up examination for eggs and/or proglottides performed 2~3 months later or 11 out of 17 scolex-unidentified cases gave all negative results. From the results it is concluded that praziquantel(Cestocide^ⓡ) in 10㎎/㎏ single dose is highly effective in treatment of these tapeworm infections.

The two microphone method for measuring acoustic intensity has receives increasing attention in recent years. In this technique one uses the signals from two closely spaced microphones to obtain a finite difference approximation of the sound pressure and particle velocity. The purpose of this paper to review the method development and to further explore the interpretation of the modeling process through the application and analysis of the noise source.

A volume integral equation method and a mixed volume and boundary integral equation method are presented for solving the elastostatic plane problems in unbounded solids containing orthotropic/isotropic inclusion and voids. The detailed analysis of lthe displacement and stress fields are developed for cylindrical land elliptic cylindrical inclusion/voids. The accuracy and efficiency of the method are examined through comparison with results obtained from analytical and boundary integral equation methods.
