딸기 시들음병균에 대한 Trichoderma 속 균의 길항작용에 관한 연구 : Ⅳ. Antagonism of T. harzianum in Soils Ⅳ. 토양에서의 T.harzianum 길항작용

문병주,정후섭,조종택 東亞大學校生命資源科學大學附設 農業資源硏究所 1994 農業生命資援硏究 Vol.3 No.2

In vitro에서 볏짚, 밀기울, 옥수수분말, chitin 또는 게껍질을 첨가하면 T. harzianum의 딸기 시들음병균에 대한 길항작용은 높았으나 clover 잎 분말에서는 낮았다. 또한 이 길항작용은 25∼30℃, 산성토양(pH 3.5-5.5), 40∼50%의 토양수분에서 촉진되었다. When rice straw, wheat bran, corn, chitin or crabshell powder was added in soil in vitro, the antagonistic activity of T. harzianum on F. oxysporum f. sp. fragariae increased, whereas incorporation of clover leaf powder had no effect on the antagonistic activity. The activity was also the highest at 25∼30℃ and in acid soil(pH 3.5∼5.5) with 40∼50% moisture content.

環境-貿易連繫 論議動向과 우리 나라 環境産業 育成方案

金成厚,金炳運 東新大學校 1997 論文集 Vol.9 No.-

Since the beginning of 1990's, GATT/WTO, OECD, UN and ISO have intensively dealt with environment-trade linkage, as the environment issues became to play more and more important role in the world economy. As a matter of fact, the intensified environment issues will result in a rapid growth of environment industry itself. The issues will also give a positive influence on Korean economy which has a poor level of environment industry, while they enlarge the market for environment industry all over the world. Thus, it is necessary for the Korean economy to positively participate in the relative world market and to compete with advanced countries. In order to survive in the competing world market, and overcome a variety of, we suggest some development strategies for environment industry as follows; First, we must change the existing industrial structure into advanced one which utilizes atomic energy, water power, tidal plant, solar power, LNG, and so on. Second, we must increase R & D investment for environment industry to catch up with industrialized contries' high-tech and know-how. Third, we must help our own environment industry grow steadily and finally survive independently with competitiveness. Fourth, we need to increase financial support which is given to the domestic environment industry that is still vulnerable. Fifth, we have to induce economic agents to pay close attention to environmental hazards through various means available. As a result, the increasing tendency of environment-trade interdependency argument in the major international organizations will enlarge the world environment market. Thus Korean economy, first of all, has to adjust the existing backward industrial structure into advanced one not to lose domestic market, and finally to take advantage of the big world market by actively participating in the related trade issues.

딸기 시들음병균에 대한 Trichoderma 속 균의 길항작용에 관한 연구 : Ⅲ. Chitinase and β-1,3-glucanase Activity Ⅲ. Chitinase와 β-1,3-glucanase 활성

문병주,정후섭,조종택 東亞大學校生命資源科學大學附設 農業資源硏究所 1994 農業生命資援硏究 Vol.3 No.1

T. harzianum은 합성 배지에 유일한 탄소원으로서 chitin, laminarin, 본 병균의 세포벽, 밑기울 분말, clover잎 분말, maltose를 단독으로 첨가하여 생육시키면 chitinase와 β-1, 3-glucanase를 생성하였으나, chitinase 활성은 세포벽 첨가구에서 가장 높았고 다음은 chitin이었으며 maltose와 밑기울에서도 높은 활성을 보였으나 clover에서는 극히 낮았다. β-1, 3-glucanase 활성은 maltose에서 가장 높았고 다음은 laminarin이었으며 그 이외에는 극히 낮았다. 양 효소의 활성은 pH 3.5와 5.5가 pH 7.5에 비하여 높았으며, T. harzianum과 본 병균을 혼합하면 단독배양에 비하여 높았다. T. viride도 유일한 탄소원으로서 chitin 또는 laminarin을 첨가하면 각각 chitinase와 β-1,3-glucanase를 생성하였으나, chitinase 활성은 T. harzianum에 비하여 현저하게 낮았고 β-1,3-glucanase의 활성은 비슷하였다. Chitinase production by Trichoderma harzianum was highest in the culture with cell walls of the pathogen or chitin, moderately high with maltose or wheat bran, and very poor with clover leaf power. Relatively large amount of β-1,3-glucanase was excreted by T. harzianum when maltose or laminarin was used as a sole carbon source for the culture of the fungus, whereas cell walls, wheat bran and clover leaf powder had little effect on the enzyme production. For both of the enzymes, the enzyme activities were higher at pH 3.5-5.5 than at pH 7.5, and higher enzyme activities were detected in the dual culture of T. harzianum and Fusarium oxysporum f. sp. fragariae than in the culture of T. harzianum alone. The activity of chitinase by T. viride was significantly lower than by T. harzianum, and the activity of β-1,3-glucanase was similar between the two antagonisitcs, although T. viride produced chitinase and β-1,3-glucanase when chitin or laminarin was added as a sole carbon source.

한국인의 대표적인 성인 고형 종양인 위암, 간암, 유방암과 소아 백혈병 및 2종의 소아 고형 종양 환자로부터 혈장 transforming growth factor-ß1 (TGF-ß1) 농도를 sandwich ELISA 분석법을 이용해 측정함으로써 TGF-ß1을 이 질환들에 대한 새로운 종양표지자 (tumor marker)로 사용할 수 있는지 검토하였다. 또한 연령 및 성별에 따른 혈장 TGF-ß1 농도의 정상치를 조사하였다. 신생아에서 70대까지 혈장 TGF-ß1 농도의 차이는 없었고 남녀간의 차이도 없었다. 위암 환자의 혈장TCF-ß1 농도는 16.0±6.8 ng/ml (평균 ±표준편차)로 정상 대조군의 TGF-ß1 농도 (8.3 ±5.0 ng/ml) 보다 유의하게 높았으나 간암, 유방암 환자의 혈장 TGF-ß1 농도는 대조군과 차이가 없었다. 그리고 위암 환자 16명, 간암 환자 8명, 유방암 환자 7명 중 각각 7명 (43.7%), 1명 (12.5%), 1명 (14.3%)에서만 혈장 TGF-ß1 농도가 증가되었다. 5명의 소아 백혈병 환자에서는 관해 (remission) 여부와 상관없이 혈장 TGF-ßl 농도가 모두 정상 범위에 있었으나 2명의 소아 고형암 환자에서는 종양 절제 전에는 혈장TGF-ß1 농도가 높았다가 절제 후 정상으로 떨어졌다. 결론적으로 1)정상인의 혈장 TGF-ßl 농도는 연령 및 성별에 따른 차이가 없다는 것을 알 수 있었고, 2)성인 고형암인 위암, 간암, 유방암에서는 낮은 민감도로 인해 TGF-ß1을 진단을 위한 선별 검사로 이용하기에는 부적절한 것으로 판단되었으며, 3) 정상 대조군보다 혈장 TGF-ß1 농도가 높았던 위암 환자와 종양 절제 전후로 혈장 TGF-ß1 농도가 민감하게 변했던 소아 고형 암 환자에 대해서는 향후 표본 수를 늘려 부가적인 연구를 해 야 할 것으로 사료된다. To evaluate the usefulness of transforming growth factor-ß1 (TGF-ß1)as a new tumor marker, we determined the plasma TGF-ß1 levels using sandwich ELISA assay in cancer patients. Patients with three most common adult cancers in Korea (stomach, liver and breast cancer) and children's cancers (leukemia and two kinds of solid tumor) were enrolled for the study. Furthermore, 39 individuals were subjected to age and sex-stratified plasma TGF-ß1 analysis. No statistical difference was demonstrated with respect to age or sex. The mean plasma TGF-ß1 level (16.0 ng/ml) of stomach cancer patients was significantly higher than that (8.3ng/ml) of controls. However, there was no difference among the mean plasma TGF-ß1 levels of liver, breast cancer patients and controls. Seven of 16 patients (43.7%) with stomach cancer, one of 8 (12.5%) with liver cancer, and one of 7 (14.3%) with breast cancer showed higher TGF-ß1 levels compared to controls. Plasma TGF-ß1 concentrations of five leukemic children remained in the normal range regardless of the remission state. In contrast, initial high TGF-ß1 levels from two children with solid tumors returned to normal range on surgical resection of tumors. From the above results, we could conclude that plasma TGF-ß1 levels of apparently healthy individuals seem to be rather constant irrespective of difference in age or sex, and the plasma TGF-ß1 has the limited value as a screening test for the diagnosis of aforementioned adult cancers because of its low sensitivity. Finally, additional studies need to be pursed for the large number of stomach cancer and pediatric solid tumor patients in order to reach a secure conclusion on the usefulness of plasma TGF-ß1 as a tumor marker in these patients.

여환호,안병후,김수관,김영균 大韓顎顔面成形再建外科學會 1992 Maxillofacial Plastic Reconstructive Surgery Vol.14 No.4

Tumors arising from nerve tissue are uncommon in the oral maxillofacial regions. Neurofibroma, a benign neurogenic tumor, can occur as circumscribed solitary or multiple lesions. A solitary neurofibroma is seldom undergo sarcomatous transformation, but fibromatosis is common. Therfore, it is important that we observe the oral and radiographic changes to help minimize the tremendous potential of the disease for facial disfigurement and altered function. The turmors were exised and there are no evidence of recurrence. The patients are satisfied with function and esthetic aspects.

본 연구는 도시방재계획의 현황을 도시계획적 차원에서 진단하고 그 발전방향을 도출하고자 하는 목적하에, 충청북도의 조례와 지침중 도시방재 관련 사항을 정리하며, 충청북도 지방도시계획위원회 회의록 및 관련자료를 검토하여 방계계획의 취급 수준을 파악하였다. 실제 도시계획 상황에 대한 진단은 도시계획 보고서를 대상으로 도시방재계획의 위상을 분석하고 평가하였다. 또한 도시방재계획의 위상과 관련 전문가의 인식수준을 평가하고 이를 바탕으로 향후 바람직한 도시방재계획의 위상을 설정하기 위해 필요한 사항을 분석하고자, 도시방재에 관한 일반의식 수준, 도시재해에 관한 대처방안, 도시방재계획의 평가방향 등을 중심으로 설문조사를 실시하였다. 이상과 같은 충북지역의 방재계획에 대한 도시계획적 진단을 바탕으로 도시방재계획 관리체계의 방향 도출과 도시방재계획의 향후방향 제안을 시도하였다. This paper examines the status quo of the existing urban disaster prevention plans in Chungbuk Province and suggests alternative orientations for the future application. Its methodological themes center around the systematic compilation and accountability of disaster-related ordinances, mostly hinged on evaluation of major disaster items documented in various urban master or revision plans. In addition, it recommends the concrete guidelines and contents in disaster prevention plans, both of which are based on the aggregated results of expert opinion survey in and around Chungbuk Province. In order to tackle with diverse and unpredictable disasters which are well observed in modern urban society, this paper urges that the relatively weak legal and planning standards of the existing disaster prevention plans have to be immediately revised. For instance, the paper vividly shows that the present dimension of disaster prevention plans within the existing master plans and perception of specialist are not satisfactory mainly because of the internal limitation of the existing plans. Secondly, it seems imperative for planners to pay attention to systematic operation and management, even starting from the early development stage of urban disasters. Lastly, it proposes the alternative checklists given to measure the suitability of the disaster plans.
