LEE, Min-Jai, HONG, Soon-Woo & LEE, In-Kyu, (Dept. of Botany, Seoul National Univ.) An analytical studies of free amino acid and its relationship among the main groups of green algae (Ⅲ). Kor. Jour. Bot. V (3) : 25-29, 1962. Succeeding the previous papers, nineteen species of marine green algae and three species of fresh water green algae are analyzed to the free amino acid patterns by paper chromatogram, and it has been described as containing significant qualities of the pattern in relation to phylogenetic studies. Those seem to have a tendency of recognizable pattern on inter-Orders and inter-Phyla of marine algae. And the patterns of fresh water and marine green algae are also carried out referring to these studies.

한국탁,이규승,이은경,이용재,고광용,원동준,이정원,권순덕 한국환경농학회 2003 한국환경농학회지 Vol.22 No.3

대전시 노은 도매시장에서 채취한 6종의 채소류 중 농약잔류량을 조사한 후 이에 대한 위해성 평가를 실시하였다. 전체 100건의 분석시료 중 농약이 검출된 시료의 비율은 46.0%이었고, 잔류허용기준 초과비율은 6.0% 이었다. 검출비율이 높은 시료는 상추(85.0%), 깻잎(80.0%), 오이(60.0%) 순이었고, 상추 3건, 깻잎 3건이 허용기준을 초과하였다. 살균제는 dicar-boximide계, 유기염소계, azole계 농약, 살충제는 유기인계, 합성 pyrethroid계 농약이 많이 검출되었다. 검출빈도가 높은 성분은 procymidone, chlorpyrifos, chlorothalonil, cypermethrin, EPN의 순이었다. 위해성을 평가하기 위해서 각 농작물에 대한 농약의 추정 섭취량과 ADI를 비교한 결과, 허용기준을 초과한 깻잎의 bitertanol, triflumizole, iprobenphos가 다른 성분에 비하여 높은 비율을 보였다. 그러나 각 농산물의 식이섭취량이 적어 ADI에 대한 추정섭취량의 비율이 0.46%이하로 나타나 그 영향이 매우 낮은 것으로 판단되었다. Pesticide residues in some vegetables collected at Noeun wholesale market in Daejeon were surveyed and assessed their risk In 100 samples, the detection rate of pesticide was 46.0% and the rate exceed MRL was 6.0%. Commodities showing high detection rate were lettuce(85.0%), perilla leaf(80.0%) and cucumber(60.0%). Dicarboximide, organochlorine, and azole fungicides and organophosphorus and pyrethroid insecticides were detected. Detection frequency of pesticide was in the order of procymidone, chlorpyrifos, chlerothalonil, cypermethrin and EPN. When the estimated intake amount of the pesticides were compared with ADI to assess their risk, bitertanol, triflumizole and iprobenphos in perilla leaf were higher rate than the other vegetables. However the total amounts of intake of pesticides were estimated to less than 0.46% of ADI.

이순혜,류규수,김문주 慶山大學校 2000 論文集 Vol.18 No.1

A study on the degree of cellulite and the factors affecting cellulite was conducted to understand the occurrence frequency of cellulite and the degree of cellulite, for students who are belonged to department of beauty artist in junior college. 240(50.3%) out of 477 had the standard shape of body, 99(20.8%) had the big frame and heavy weight, 75(15.7%) had the typical woman shape of body, and 63(13.2%) were tall and slim. 204(42.8%) out of 477 had the dry skin,186(39.0%) had the fatty skin and 87(18.2%) had the normal skin. The results of the study are summarized as follows ; 1. The cellulite condition, the physiological factor, the psychological factor(p<0.001), the diet factor, the constitutional factor(p<0.01) and the physiological factor (p<0.05) were different, by school year. The cellulite condition was different by the place which school was in(p<0.001).By shape of body, the cellulite condition, the habit of life, the psychological factor, the physiological factor (P<0.001) and the diet factor, the constitutional factor(P<0.05) were different. The cellulite condition, the physiological factor(p<0.01) and the constitutional factor(p<0.001) were different by degree of corpulence. The habit of life(p<0.01), the constitutional factor (p<0.05) were different by religion, and the diet factor was different by status of economical class (p<0.05). The diet factor (p<0.001), the cellulite condition, the psychological factor (p<0.01)and the physiological factor, the physiological factor (p<0.05) were different by status of skin. The physiological factor (P<0.001), the cellulite condition, the habit of life, the diet factor, the constitutional factor(p<0.01) and the psychological factor (p<0.05) were different by place which student lived in. 2. Each factor has positive relation with cellulite condition. The correlation coefficients of factors were the physiological factor (0.565), the diet factor (0,433),the habit of life (0.428), the constitutional factor (0.271) and the psychological factor (0.264) respectively. 3. According to the result of regression analysis between each factor and cellulite condition, the regression coefficient of the diet factor was 0.236, that of the habit of life was 0.206, that of the constitutional factor was 0.086, and that of the psychological factor the constitutional factor was 0.108 (P<.001).

This study aims to suggest an activating programs through leading farmers' preference analysis for homepage operation and e-commerce using binary logit model. The results showed that leading farmers' preference for homepage operation increased more as the period of internet using and livestock raising was longer, the intention of e-commerce was higher. They also showed that leading farmers' preference for e-commerce increased more as the period of internet using was longer, as age level was higher and non-livestock raising. Therefore the strategies for the activating programs of homepage operation and e-commerce are the strengthening of education about homepage operation and e-commerce for leading farmers, the linkage with a e-commerce, the enlargement of budget for them, the considerations of age level and items of crops or livestock, the support for leading farmers for e-commerce.

인터넷은 디지탈 형태의 다양한 정보를 신속하게 전달한다는 점에서 매우 각광을 받고 있다. 그러나, 대량의 인터넷 정보 중에서 자신이 원하는 정보 자원을 정확하게 많이 얻어 낼 수 있는 방법의 제공은 매우 어려운 문제이다. 본 논문에서는 인터넷 정보 자원의 메타데이타를 관리하기 위해 SeriCore라는 SGML 형식의 메타데이타 DTD(Document Type Definition)를 정의하고, 이들 메타데이타를 효율적으로 저장하고 검색, 관리할 수 있는 시스템을 설계, 구현하였다 The Internet has gained popularity because ot provides various information in digital format. However, it is very difficult to provide methods which make it possible to search adequate information resource from bulk of Internet information. In this paper, we define a SGML metadata DTD, named SeriCore, and design and implement a metadata retrieval and management system which can store, retrieve and manage the Internet metadata efficiently

이주영,류수진,박예진,황순호,이마세,김인종,김동현,김신규 慶熙大學校 1996 論文集 Vol.25 No.-

Sythesis of β-naphthol derivatives and their anti-tumor activity were investigated. Binaphthol 1 obtained from β-naphthol by oxidative C-C bond formation(phenoloxydation) was converted into its derivatives. Treatment of 1 with POCl_3 followed by aziridine introduction gave phosphoryl aziridine 3. Also, diaziridine 5 was obtained from 1 by chlorination and successive aziridine introdution. Typical chemical transformation of 1 to obtain ester-type afforded compound 7 and 8. Compound 5 was the most effective derivative of the tested compounds on their anti-tumor activity.

This study was compared pre-operative MRI finding with operative finding on 36 cases with the failed back surgery syndrome (FBSS) retrospectively. The purpose of this study was to determine the accuracy of the MRI on the FBSS including early complications such as hematoma of infection. Of the 51 patients with FBSS, we analyzed pre-operative MRI finding compared with operative finding on 36 cases excluding nonunion, instability, metal failure and pseudoarthrosis who underwent an operation for the FBSS from December 1994 to June 1997. There were 25 men (69.4%) and 11 women (30.6%), aged from 16 to 68 years (average 43.6 years). These were divided into 5 sub-groups and calculated sensitivity, specificity and positive predictability. MRI accuracy in recurred disc was 84%, scar adhesion, recurred or developed stenosis, infection and hematoma 100% each and all, overall accuracy of the MRI 93%, respectively. Average interval of re-operation in FBSS WAS 4.3 years. In the 18 cases (50%), symptoms persist without pain-free interval after first operation. Early complications including hematoma and infection are easily detected with MRI. Especially if patient complains of severe leg pain or neurologic deficit, it is a good diagnostic procedure to check the MRI. The MRI is a useful method for evaluation of most cases of the FBSS, but it has limitations to evaluate recurred disc or scar adhesion only in T1, T2 weighted image. Therefore Gd-DTPA enhancement is necessary for the accurate diagnosis.
