본 시험의 목적은 대구 경북에 자생하는 헤어리베치로 다수성 조생품종과 중만생품종을 개발하기 위하여 수행하였다. 경북 성주와 경남 사천에서 1998년부터 2006년까지 자료수집 및 순화, 생육이 왕성한 조생 및 중만생계통선발, 상호교잡의 단순순환선발법으로 조생종인 콜드그린과 중만생종인 청파를 육성하였다. 육성종자는 2004년부터 2006년까지 경북성주와 경남사천에서 생육특성과 수량을 평가하였다. 줄기의 털은 콜드그린과 청파는 있었으나, 헤이메이커프러스와 라티고는 없었다. 잎의 모양은 콜드그린은 엽폭이 넓은 장타원형이고, 청파, 헤이메이커프러스, 라티고는 좁은 장타원형이었다. 꽃색은 콜드그린은 자주색이고 청파는 보라색이었다. 내한성은 성주에서 콜드그린, 청파, 라티고가 헤이메이커프러스 보다 높았으며 사천에서는 차이가 적었다. 개화기는 콜드그린과 헤이메이커프러스가 조생종으로 유사했고 중만생종인 청파는 라티고 보다 다소 빨랐다. 성주에서 건물수량은 콜드그린이 다른 품종 보다 높았으며 청파와 헤이메이커프러스는 라티고 보다 높았다(P<0.05). 2005년 사천에서는 콜드그린과 헤이메이커프러스는 다른 품종보다 높았으며, 청파는 라티고 보다 높았다(P<0.05). 베치의 조단백질 함량은 높고 ADF의 함량은 낮았다. The objective of this research was to develop a high yielding, early and medium-late flowering new hairy vetch(Vicia villosa Roth) varieties derived from an accession in Korea. Most vigorous early and medium-late flowering hairy vetch lines were selected and crossed by open pollination and their seeds were bulked and plants were reselected at Seongju in the Keongbuk and at Sacheon in the Keongnam. A performance trial was conducted to evaluate agronomic characteristics, forage quality and dry matter(DM) yield of new hairy vetch early-maturing 'Cold green' and medium-late maturing variety 'Cheong pa' at Seongju and Sacheon. 'Cold green' and 'Cheong pa' are hair but 'Haymaker plus' and 'Latigo' are nearly hairless. 'Cold green' has purple flowers while 'Cheong pa' has violet. The cold tolerance of 'Cold green,' 'Cheong pa' and 'Latigo' was higher than 'Haymaker plus' at Seong-ju, Keongbuk province, in inland region but there were a little differences at Sacheon, Keongnam province in southern coast region. Fifty percent-flowering dates of 'Cold green' and 'Haymaker plus' had earlier than others and 'Cheong pa' was earlier than 'Latigo'. The DM yield of 'Cold green' was higher than that of others, but 'Cheong pa' and 'Haymaker plus' had higher than 'Latigo' at Seong-ju(P<0.05). In Sacheon, The DM yield of 'Cold green' and 'Haymaker plus' was higher than others and 'Cheong pa' had higher than 'Latigo'.

In this research, the optimum LFG pilot plant of extraction, purification, and application are selected by economic analysis, constructed and operated for the development of the standard LFG utilizing process process proper to domestic landfill. LFG recovery pilot plant was constructed at the base of the result of optimized design and economic evaluation performed at S,D landfill(landfil1 area : 514,345m², landfill depth : 23-39m, landfill MSW amount : 12,808,317m³, landfill period : 87.6-93.5) in Pusan. It was consisted of four extraction well(two extraction well with 18.5m depth, two extraction well with 10m depth), collection head with 160m length, scrubber with capacity 14m³/min as purification process, and flare stack as burning facilities. And monitoring well was set at 30, 50, 70, 90m far from extraction well for the estimation of influence radius. The following experiments were performed using the predeveloped LFG reconvery pilot plant. First, LFG generation amount and generation rate were estemated from the atom analysis of municipal solid waster in S,D landfill. Second, real LFG extraction rate of some 0-10㎥/min was obtanied from operating of LFG recovery process. Third, influence radius was estimated 85-100m according to varying 407㎥/min extraction rate. Fourth, composition of LFG was detected in extraction well and the before and after of purification process.

Most shipbuilding works are manually carried out by workers, and safety consideration is an important issue especially in elevated-spot works such as painting and cleaning of outer wall of a ship. To cope with the circumstance, shipbuilding makers start to introduce wall-climbing robots for carrying out such tasks. In designing such a wall-climbing robot, it is essential to minimize its own weight to improve the performance such as moving speed and power saving. For such purpose, this paper proposes a method of optimal design for a wall-climbing robot body using genetic algorithm through static and dynamic analysis. Specifically, the thickness of the robot base is minimized to reduce the weight while maintaining the allowable strength and avoiding resonance frequencies. The proposed method is applied to the design of a wall-climbing robot, and the simulation results show that the method can be successfully adopted to the early stage of design.

This work is dedicated to main directions of Agricultural science policy of Russia during the transition to the market economy. In this study, Russian R&D system, R&D expenditure and structure of research institutes were introduced. Especially, Studies on organizations such as RFBR : Russian Foundation for Basic Research, RFTD : Russian Fund for Technological Development, Russian Foundation for Promotion of Small Enterprises in S&T, FPP : Fund for presidential Programs, SRC : State Research Center, ISTC : International Science & Technology Center were carried out. Analysis of the problems of Agricultural Science sector of Russia shows the situation is very complicated. Despite all efforts of Government, the national institutes is still in crisis. It is clear today that without energetic and intelligent reforms, it would be impossible to implement resonable reorganization of Agricultural sector and have to strong and deserved science and technical sector in Russia.

The thermal decomposition of the sludge with Poly(acryloniti1e-butadiene-styrene) and Poly(styrene-co-acrylonitrile) were using a thermal analysis techniques in the stream of nitrogen gas of 30ml/min at various heating rates from 4 to 20℃/min. The mathematical, Derivative and Integral method were used to obtained values of activation energy of decomposition reaction. 1. The values of activation energy evaluated by Derivative and Intergral method were consistent with each other very well. 2. The maximum value of heat of decomposition evaluated by DSC method were 10, 120 cal/g at weight ratio of sludge/ABS=20/80 and 10, 500cal/g at weight ratio of sludge/SAN = 20/80. 3. The thermogravimetric trace curve agreed with the theoretical equation.

The necessity of the internet-aided instruction, and the advantages and restrictions of it were widely investigated as theoretical background, and the general principle of designing the instruction, model of procedure in science class, practical design of the internet-aided instruction procedure of it's development and effective approach of web design. On the basis of the above, experiment contents of 10 units in highschool common science (department of chemistry)were reconstructed, and deployment plan for teaching-learning guidance papers for experiments, reports of experiments, individualized problem for evaluation, self-learning references, guidance papers for teaching, figure files for forming concepts and principles were made. Experimental unit of chemical reaction speed which is difficult for the first grade highschool students is established, and it is made a form of CD-ROM title with animation and presentation techniques. As a result, Learning environment which raised learner's motivation was presented. Further more, based on web instruction model and instruction design principle for learning with internet, teaching-learning home page with HTML was made.

This paper is a method to maintain the right of possesion for color images. previous method used an binary data, image, or binary pattern etc. So watermarked image was declined in image quality. But the information for insertion was limited. This paper proposed the method which will change RGB mode of original image to YIQ, at first, we will insert the watermark in the Low frequency cofficient of wavelet transform domain. The watermark use the owner's photo of a digital contents. which is 256 gray-level watermark, and it's size can be changed by the size of original image. As the result of simulation, our method can provide the rightful1 ownership against Rotation, Cropping, JPEG, and Scaling attacks.
