The major problems of food crop cultivation in Korea are low yield of most crops except rice. inefficient cultivation techniques for aged farmers. and low international competibility. Therefore, development of cultivation techniques of food crops should aim the yield. quality improvement, labor reduction and production cost. The primary issue for increasing the yield of soybean, barely and wheat is to reduce the yield gap between the farmer's yield and recommended ones of experiment station. More advanced cultivation techniques needs to be developed. and/or the conventional breeding methods to be reconsidered. The newly developed labor-saving mechanized technique needs to reduce labor hours , and the cost of agricultural implements and machineries. In other words the labor-saving mechanized technique should be developed based on the improvement of total farming system as well as systemic fundamental innovation of cultural methods. The efficiency of solar energy use in food production of Korea in 1997 is as low as $0.52{\%}$ so there is much room to increase yield. It is recommendable that the concept of food Production should be changed to energy Producing efficiency Per unit area basis from volume and weight of food materials. Moreover, introduction of resonable cropping system is needed to increase yield of main crops, farmer's income, solar energy use efficiency, and decrease of land service expenditure. Current cropping system emphasized on economic crops. especially in vegetables , is not desirable for resonable use of arable land. stability of agricultural management and staple food crop self-sufficiency ratio. It is desirable to increase food crops . that are energy of carbohydrate and protein rich and land dependent crops. in cropping system. And the agronomist should develop the cultural methods to replace food crops for food self-sufficiency and stable farming management instead of economic crops in current cropping system. Low-input and environmentally-sound crop cultivation techniques, especially nitrogen-reducing culture technique which is directly related to food crop quality, also needs to be developed urgently. The extended cultivation of corn in upland and barely and wheat in lowland as a feed stuffs is recommended to prevent further decrease of food self-sufficiency ratio, which is mainly caused by the high reliance on imported feed grain. It is also considered that the calculation and presentation methods of standard agricultural income needs to be improved. The current calculation method uses unit land area of 10a regardless of crop kinds , characteristics of agricultural management and cultivation scale. So, it is apt to lead misunderstanding of farm income value. Therefore. it should show an income of average farmers for certain number of years. Research and developing system for food producing is not desirable because they are conducted currently individual crop and mono-culture basis. But actual agricultural income is usually earned by cropping system including upland and lowland. For example. the barley and wheat is usually cultivated in double cropping system. The cooperation among research institutes such as university agribusiness. government and farmers is indispensible. The public information and education on importance and consumption habit of food crops is necessary in Korean society to increase food self-sufficiency through nationwide cooperation.

본 연구는 우분액비 및 녹비작물 도입에 의한 답리작 사료작물을 재배하여 수확한 다음 우분액비시용이 벼 및 후작물인 답리작 사료작물의 생산성, 토양의 지력증진 효과 및 양분이동에 미치는 영향을 조사하기 위하여 전라북도 축산진흥연구소내 식양토의 논에서 2006년 4월부터 2009년 4월까지 3개년에 걸쳐 수행하였다. 우분액비 시용은 벼는 이앙 전에 전량 기비로 시용하였으며 총체보리 및 호밀은 파종전과 봄 생육 개시 전에 2회 균등분할 시용하였는데, 화학비료 대비 우분액비의 시용수준은 N를 기준으로 하였다. 처리는 벼 화학비료 단작 표준구, 벼+ 총체보리 2모작 우분액비 시용구, 벼+호밀 2모작 우분액비 시용구, 벼+자운영 및 벼+베치로 구성하여 5처리 완전임의배치 3반복으로 배치하였으며 벼는 농가관행에 준하여 재배되었다. 3개년 평균 벼 수량구성요소 및 수량에 있어서 초장 및 수장은 화학비료 단작 표준구가 가장 길었으며 경수 및 낱알 수도 화학비료 단작 표준구가 가장 많았다. 등숙율은 화학비료 단작 표준구, 총체보리 우분액비 시용구 및 호밀 우분액비 시용구가 비슷한 수준으로 자운영 단작구 및 베치 단작구에 비해 높았다. 현미수량은 화학비료 단작 표준구가 가장 많았고 자운영 단작구 및 베치 단작구는 비슷한 수준으로 총체보리 우분액비 시용구 및 호밀 우분액비 시용구에 비해 낮았다. 벼와 2모작으로 재배한 총체보리의 수량이 호밀에 비해 더 높게 나타났다. 경작형태별 우분액비시용에 따른 토양내 pH, $P_2O_5$, T-N, OM 농도 및 치환성 양이온의 농도는 시험전에 비해 시험종료후에 현저하게 증가하는 경향을 나타냈다. 배출수 중 $NO_3$-N, $NH_4$-N 및 $PO_4$ 농도는 총체보리 및 호밀 우분액비 시용구가 화학비료 단작 표준구에 비하여 약간 높게 나타났으며 이앙 후 시일이 경과할수록 낮아졌다.

In order to overcome the problems of contact palmprint recognition, a non-contact palmprint recognition system is developed on personal computer (PC) platform. Three methods, namely "double-line-single-point" (DLSP), "double-assistant-crosshair" (DAC) and "none-assistant-graphic" (NAG), are implemented for the palmprint localization to solve the severe technical challenges, including the complex background, variant illuminations, uncontrollable locations and gestures of hands. In NAG, hand segmentation and the cropping of region of interest are performed without any assistant graphics. The convex hull contour of hand helps detect the outside contour of little finger as well as the valley bottom between thumb and index finger. The three methods of palmprint localization have good operating efficiency and can meet the performance requirements of real-time system. Furthermore, an attendance system on PC platform is designed and developed based on non-contact palmprint recognition.
