In order to develop a high cellulolytic direct-fed microorganism (DFM) for ruminant productivity improvement, this study isolated cellulolytic bacteria from the rumen of Holstein dairy cows, and compared their cellulolytic abilities via DM degradability, gas production and cellulolytic enzyme activities. Twenty six bacteria were isolated from colonies grown in Dehority's artificial (DA) medium with 2% agar and cultured in DA medium containing filter paper at $39^{\circ}C$ for 24h. 16s rDNA gene sequencing of four strains from isolated bacteria showed that H8, H20 and H25 strains identified as Ruminococcus flavefaciens, and H23 strain identified as Fibrobacter succinogenes. H20 strain had higher degradability of filter paper compared with others during the incubation. H8 (R. flavefaciens), H20 (R. flavefaciens), H23 (F. succinogenes), H25 (R. flavefaciens) and RF (R. flavefaciens sijpesteijn, ATCC 19208) were cultured in DA medium with filter paper as a single carbon source for 0, 1, 2, 3, 4 and 6 days without shaking at $39^{\circ}C$, respectively. Dry matter degradability rates of H20, H23 and H25 were relatively higher than those of H8 and RF since 2 d incubation. The cumulative gas production of isolated cellulolytic bacteria increased with incubation time. At every incubation time, the gas production was highest in H20 strain. The activities of carboxymethylcellulase (CMCase) and Avicelase in the culture supernatant were significantly higher in H20 strain compared with others at every incubation time (p<0.05). Therefore, although further researches are required, the present results suggest that H20 strain could be a candidate of DFM in animal feed due to high cellulolytic ability.

본 연구는 홀스타인 젖소의 반추위에서 순수분리 및 동정된 섬유소 분해균인 Ruminococcus flavefaciens (H-20) 및 Fibrobactor succinogenes (H-23)의 혼합 배양액(DFM)을 수준별로 반추동물에 적용하였을 때 반추위발효와 섬유소분해효소 활성에 미치는 영향을 평가하였다. 대사시험은 반추위 fistula가 장착된 12개월령 한우 암소 4두를 이용하여 $4\times4$ Latin square 방법으로 실시되었다. 모든 처리구는 기초사료로, 농후사료 2 kg에 톨페스큐와 오차드그라스의 혼합건초 3 kg을 1일 2 회로 나누어 균등 급여하였으며, DFM을 사용하지 않은 처리구(control), 기초사료를 포함하여 1% (50 ml/day, H20 + H23), 3% (150 ml/day, H20 + H23) 및 5% (250 ml/day, H20 + H23) 수준의 네 처리군으로 나누어, 사료 급여시 DFM을 반추위 cannula 안으로 직접 주입하여 실시하였다. 본 실험 결과 급여 후 모든 시간에서, 처리구는 반추위액내 pH의 유의적 차이가 나타나지 않았으나, 반추위 암모니아 질소의 농도에서 DFM투여 후 1시간에 3% 처리구(19.47 mg/dl)는 5% 처리구(17.27 mg/dl)와 차이는 없었지만, 대조구 및 1% 처리구(14.5 및 14.9 mg/dl)와 비교하여 유의적으로 높은 농도를 보였다(p<0.05). 섬유소분해효소활력은 전체적으로 유의한 효과가 나타나지 않았으나, xylanase는 0시간에 5% 처리구($119.49\;{\mu}mol$/ml/min)가 3% 처리구($72.02\;{\mu}mol$/ml/min)와 비교하여 유의적으로 높은 농도를 보였다(p<0.05). VFA 농도는 butyric acid에서 급여후 1시간에 대조구(15.71 mM)와 비교하여 3% 처리구(24.48 mM)에서 유의적으로 높은 농도를 보였다(p<0.05). 이러한 결과로 미루어 보아 혐기성 섬유소분해 박테리아 배양액의 공급은 최소 3% 이상에서 반추위발효에 개선효과가 있는 것으로 나타났다.

The navigation problem of robot is one of the main themes to deal with conficts or interferences between obstacles and the robot itself In this case, while the robot avoids obstacles on the space, the passage route should be determined efficiently. In order to solve problems above, we have come up with the distance field space medel (DFM) and then, under known environment, we have presented the distance field A algorithm for passage route path search. In this research, the method of performing the 3-dimensional passage route path search of robot under unknown environment is proposed. It is shown that the authors can build the distance search model the does not need space division by taking into account of sensor information to a distance field space model, and constructing this information as virtual obstacle information.

In this paper a web-based micro fabrication system is discussed. A commercial CAD and a web browser were used as its user interfaces. In these user interfaces the concepts of Design for Manufacturing (DFM) was implemented providing the fabrication knowledge of micro machining to the designers. Simple databases were constructed to store the fabrication knowledge of materials, tools, and micro machining know-how. The part geometry was uploaded to the web server of this system as an STL (Stereo Lithography) format with process parameters for 3-axis micro milling. A Slice-based process planner automatically provides NC codes for controlling micro stages. A couple of micro parts were fabricated using the system with micro endmills. This design and manufacturing system enables network users to obtain micro-scale prototypes in a rapid manner.

In this paper, we propose a 7-phase life cycle model which applies to Computer Integrated Manufacturing systems. The model emphasizes product design and manufacturing design activities of CIM to secure the critical success factors of CIM systems such as high quality, adaptability, productivity, and flexibility. It is argued that the product design aspect would be divided into three phases-conceptual design, embodiment design, and detialed design. The conceptual design phase is to build a conceptual model of the product based on requirements and specifications which reflect "the voice of the customer". THe embodiment design phase utilizes specific design tools such as DFM, CAE, and CAD, and results in a concrete model of the product and parts. The detailed design phase is to crete a working prototype of the product and design tools such as DFA. CAD and CAM are employed in this phase. The output of the product design activity is to be the input for the manufacturing design activity. Using the proposed model, one can effectively and efficiently manufacture a high-quality, low-cost product with short delivery time, and above all achieve customer'ssatisfaction.isfaction.

댐 붕괴에 따른 홍수파의 전파 및 이에 따른 하류 제내지 범람은 그 영향범위가 매우 광범위하고, 흐름 양상이 복잡하며, 하도와 범람원 사이의 제방 붕괴특성에 따라 모의 결과가 달라지는 특징이 있으나, 이러한 요소를 모두 만족스럽게 재현하기가 어려운 실정이다. 본 연구에서는 1차원(1-D) 홍수파 해석 모형과 2차원(2-D) 제내지 범람모형을 제방붕괴 모듈로 연계하여, 1-2차원 연계 극대홍수파 해석 모형(2DFM)을 개발하였다. 제방의 붕괴 원인은 여러 가지가 있을 수 있으나, 하천의 수위가 제방고를 초과하는 경우 월류에 의한 제방의 붕괴가 시작되는 것으로 설정하였으며, 제방붕괴 과정은 시간경과에 따른 붕괴폭과 붕괴심의 변화를 설정하여 파제부의 월류량으로 범람홍수량을 결정하고 2차원 범람모형과 연계하였다.
