Time pasages could deteriorate the flow ability and hold the flow in the water distribution facilities because of their erosion and breakdown. It is necessary that the study to determine the optimal change time and the improvement plan for the continuous management using optimization methods or decision support systems. But, the present study tendency only aware the changes of hydraulic characteristics without industrial management plans. This study shows the pipe replacement program in these two concepts and the elementary process to apply it to Daejeon city.

우리는 지금 경제적, 사회적, 기술적으로 매우 중대한 전화기에 처해 있다. 세계적으로는 기술보호주의와 국제적인 물질특허의 장벽을 넘어야함과 동시에 국내적으로는 건강한 삶, 깨끗한 환경, 풍요로운 사회건설을 통한 복짓회의 구현이 강력하게 요망되고 있기 때문이다. 이와같은 당면과제를 슬기롭게 극복하고 다가오는 21세기의 과학기술 선진국으로 진입하기 위하여는 여러가지 연구부문을 생각할 수 있겠지만, 특히 미생물 내지는 천연물로부터 다양한 대사기능을 갖는 새로운 생리활성 선도물질(lead moldecule)의 탐색연구가 매우 중요하리라 생각된다. 이는 국제적인 물질특허제도 등의 기술보호주의 장벽을 넘을 수 있음과 동시에 부가가치가 높고 세계시장을 확보할 수 있는 거대시장이 기다리고 있기 때문이다. 따라서 현재 정부정책 연구사업으로 추진하고 있는 G7 신기능 생물소재 연구 중 생리활성 선도물질 탐색기술 개발연구가 중과제로 선택된 것은 아주 시기적절한 결정이었다고 할 수 있다.

This is the study on the feature of workability and engineering properties of flowing concrete using the superplasticizing agents which is using to effect considerable reductions in water contents in the same level of consistemcy and workability. It is the aim of this study to compare workabili쇼 and engineering properties of flowing concrete according to the addition time and method of superplasticizing agents. In this experimental study, 2cm slump of concrete, 18cm slump of conventional concrete, two kinds of aggregates and addition time and method of superplasticizing agents of 0, 15, 30, 45, 60 and 90 minutes were included to analyze and investigate the workability and engineering properties of flowing concrete.

An improved method for the selective isolation of high-yielding mutant strains for the production of antifungal antibiotic KRF-001 was investigated. The mutant strain U. V 4, which produces high titer of KRF-001, was selected on the high potency agar plate after ultraviolet light irradiation. The U. V 4 strain produced 2-fold more KRF-001 than the mother strain in production media. Large scale fermentation was performed using the U. V 4 strain in 100$\ell$ fermenter. The antifungal antibiotic KRF-001 secreted into culture broth was detected by HPLC in 24hrs of fermentation.

Using conidia of Neurospora, changes in respiratory activities and the sensitivity to the ultraviolet light of the cells at different growing stages were measured by manometric methods, and the correlation between them was observed. Efficiency in the utilization of various carbon sources, such as, glucose, sucrose, maltose, starch and sodium acetate, in growth and exogenous respiration of N. crassa was also determined. Growth rate of N. crassa was decreased considerably in the medium containing sodium acetate than in the glucose medium and was almost zero in the lactose medium, whereas the utilization of sucrose, maltose and starch was ve교 high, as that of glucose. Respiratory activities of the cells veried considerably depending upon their different growing stages. Actively growing hyphae exhibited the greatest activity in exogenous glucose respiration, followed by germinating and activated conidia in decreasing order. There was no proportional relationship between the dose of ultraviolet light irradiated and its effect on the respiratory activity of the cells, though the more the dose of ultraviolet light, the more the injury. The sensitivity of the cells to ultraviolet light varied with the different respiratory activities of the cells linked to the developmental stages. In general, the more actively growing cells having high respiratory activities exhibited the more serious injury.

Among total 176 strains with antialgal effects isolated from So-ok stream in Korea, Pseudomonas aeruginosa AJ1 showed the highest removal efficiency for an algal species Microcystis aeruginosa (clear zone of diameter 50.0 mm on algal lawn after 20 days). The algal growth was suppressed even when the supernatant of AJ1 culture was applied, suggesting that extracellular substances are responsible for its antialgal activity. The removal activity of AJ1 was optimal under the following condition: pH 8, $30^{\circ}C$, and mannitol as a carbon source. The antialgal activity of AJ1 appeared to be dependent of the growth phase of M. aeruginosa, i.e., the highest at the early phase, but not its own phase. As expected, the algicidal effect was improved as the amount of the treated supernatant was increased; the highest removal efficiency (80.3%) was achieved when 40 ml/L of the supernatant was used. Interestingly, however, the removal rate was opposite. The highest removal rate ($8.2{\mu}g$ chl-a/ml supernatant/day) was achieved when low concentration (10 ml/L) was applied. These results suggest that P. aeruginosa AJ1 is a promising biological agent to control the problematic algal bloom.
