이상곤 한국기술교육대학교 2003 論文集 Vol.10 No.1

This study examines the impacts of the three key actors' competencies: vendor competence, IS staff competence, user competence, and their partnerships among them: internal partnership, external partnership on the performance of OISD projects. The OISD success is measured by process control and system quality. Data was collected from 67 OISD projects in Korean business firms. This result shows the importance of internal IS staff in OISD projects by showing that the competence of internal IS staff and their partnership together with users or external vendors are critical factors in determining OISD success. In addition, several implications are presented, and future directions are suggested.

Ordinarily stow net fisheries was used by floater beam and sinker beam for the purpose of spreading the mouth of net. But it was not only iuconvenient and dangerous but much defective. In this thesis, we have studied fundermental experiment of the improved stow net fishing gear using head rope, ground rope and otter sail instead of floater beam and sinker beam. From the result of this experiment, it has been succeeded for fishing work to achieve basically without any difficulty. The results obtained in this study were as follows. 1) The resistance of fishing gear was estimated R≒7V2 as possible as it is taken greatly. (R: Resistance V: the rate of current) 2) The interval of otter sail was spreaded smoothly. Being in normal condition, it was maintamed the width 37-38m. It was heared comparison with net mouth of ordinary gear, and the shearing force was enough. 3) The height of mouth was lower than we have anticipated to and seemed to have the supplement of buoyancy. But according to increasing the rate of current, the lowness of mouth height was little affected. 4) The height of otter sail was decreased at the rate of 30% by the rate of current, on the contrary, the height of wing was not decreased owing to sufficient buoyancy, 5) The adjustment of extention length of hanging wire(connected with fishing boat) and raising wire(with otter sail) was great important problem and it must be dealed with the most moderatly because of a corelation between the spreading of fishing gear and catching ability. 6) On the depth of 30m, it was taken 25 minuits to cast anchor and lines, 20 min cast net, 24 min haul net, 45 min haul lines and heave anchor, respectively. 7) The improved stow net with otter sail was cleared up the defects and difficult problems in ordinary gear using floater beam and sinker beam, and it have more advantages of fishing work than ordinary one. But there were involved in lots of problems in details to solve in the future.

This study is intended to provide a more effective curriculum for the In- Service Training Program of industrial technical teachers. The curricula which have been used during last five years were carefully analyzed and the main conclusions are suggested as follows; 1) It must be given to the teachers to take optional subjects. 2) Experiments should be reinforced make up for the understanding of theory. 3) Practical studies and factory investigations have to be provided to the teachers during the In-Service Training Program. In case of needs, the expert engineer of industries become a instructor to the teachers for explaining the up-to-date industrial techniques and theories. 4) The teachers who attending the In- Service Training Program should take an active interest in the program for getting a remarkable results.

발암물질 N-Nitrosodipropylamine의 미생물학적 분해

발암물질 N-nitrosodipropylamine을 유일한 탄소원으로 이용하여 분해시킬 수 있는 세균을 하천수와 토양으로부터 분리하였으며 미들 중 분해능이 우수한 EL-02311S isolate를 propionibacterium sp.로 동정하였다. Propionibacterium sp.EL-02311S는 N-nitrosodimethylamine. N-nitrosodibutylamine, N-nitrosodiethanolamine 등을 탄소원으로 이용할 수는 없었으나 이들N-nitroso compounds를 산화시켰다. Propionibacterium sp. EL-02311S에 의한 N-nitrosodipropylamine 의 분해는 gas chromatography에 의해서 측정되었으며 배양시간이 40시간정도 경과된 early stationary phase때까지 약 50%의 높은 분해율을 나타내었다. The bacteria capable of utilizing N-nitrosodipropylamine as a sole carbon source were isolated from soil and sewage water by enrichment culture. The isolate designated as EL-02311S had high biodegradability on N-nitrosodipropylamine and was identified as propionibacterium sp. N-nitrosodimethylamine. N-nitrosodibutylamine, and N-nitrosodiethanolamine were not utillized as a solecarbon source. The N-nitroso compounds that did not serve as growth substrates were oxidized in oxidation tests using resting cell of propionibacterium sp. EL-02311S. The determination of N-nitrosodipropylamine was measured by a gas chromatography. About 50% of N-nitrosodipropylamine was degraded in early stationary phase of 40 h culture.

The purpose of this study is to elucidate the effects of regular swimming exercise on blood lipoprotein metabolism and leptin. In this study, swimming(HRmax 50-75%, 60min/day, 5day/week) was performed and 18 were participated for study during 16 weeks. They were divided into two groups, one group as experimental group(n=9) and the other as control group(n=9). A measured factors were TC, TG, HDL-C, LDL-C and leptin.. All data were expressed as mean± standard deviation by using spss package program(win 9.0), one way anova and independent t-test was used to analyze the difference of exercise duration(0week, 8week, l2week, l6week) between groups. For all statistics performed statistical significance was set at p<.05. After exercise intervention, TC, TG, HDL-C, LDL-C and leptin were found to have more significant effects in the experimental group than control group. This results indicated regular swimming exercise training is beneficial to prevent and treat cardiovascular disease and obesity.

We propose a new record and retrieval system for monitoring video data which is based on image analysis technique to increase the efficiency of video monitoring system. In General, most developed system monitored and saved all region including background and target region. But we can only obtain target region effectively, not through background and object region. And also, in order to recognize the monitoring target correctly, we need several target region image which have various poses and directions.

We investigated resistive superconducting fault current limiters (SFCLs) fabricated using YBCO thin films on 2-inch diameter sapphire substrates. Nearly identical SFCL units were prepared and tested. The units were connected in series and parallel to increase the current and voltage ratings. A serial connection of the units showed significantly unbalanced power dissipation between the units. This imbalance was removed by introducing a shunt resistor to the firstly quenched unit. Parallel connection of the units increased the current rating. An SFCL module of 4 units in parallel, each of which has minimum quench current 25 A_(peak), was produced and successfully tested at a 220 V_(rms) circuit. From the resistance increase, we estimated that the film temperature increases to 200 K in 5 msec, and 300 K in 120 msec. Successive quenches revealed that this system is stable without degradation in the current limiting capability under such thermal shocks as quenches at 220 V_(rms).
