볏짚과 볏짚으로 만든 퇴비, 그리고 녹비작물인 헤어리베치를 시용하여 벼의 생육과 수량, 토양의 이화학적 특성에 미치는 영향을 조사한 결과를 요약하면 다음과 같다. 벼의 시기별 생육상황은 삼요소구에 비하여 유기물원인 볏짚과 퇴비 시용구에서 초장 및 경수가 감소하였으며, 헤어리베치 시용구는 삼요소구와 비슷한 경향을 보였으며, 수량 및 수량구성요소에서 주당 수수는 삼요소구가 가장 높았고, 유기물 시용 간에는 차이가 없었으며, 수당 립수는 헤어리베치 시용구에서 가장 낮은 경향을 보였다. 천립중은 처리간에는 차이가 없었으며, 등숙률은 삼요소구에 비하여 유기물 시용구에서 약간 증가하는 경향을 보였다. 수량은 삼요소구(100%)에 비해, 퇴비 시용구(77%), 볏짚 시용구(72%) 및 헤어리베치 시용구(103%) 순으로 나타났다. 유기물 시용으로 토양의 용적밀도의 감소와 이에 따른 공극률을 증가시켰으며, 결국 유기물시용이 토양의 물리성을 양호하게 하는 것으로 나타났다. This experiment was performed to study growth and yield of rice (cv. Dongjinbyeo) and soil properties affected by the application of rice straw, compost, and hairy vetch. An application of rice straw and compost led to the decrease in plant heights and tillers compared with chemical fertilizer whereas hairy vetch application resulted in slight increase. Panicle no per plant was the highest in chemical fertilizer and there was no difference among organic matters. Grain per panicle was no difference among chemical fertilizer, rice straw, and compost whereas was the lowest in hairy vetch application. The 1,000 grain weights did not show any statistic difference and the ripened rate was enhanced in all treatments of organic sources compared with chemical fertilizer. Therefore, an index of rice yield of compost, rice straw, and hairy vetch to chemical fertilizer (100%) was 77, 72, and 103%, respectively. In addition, an application of organic sources led to the increase of soil pore space and this contributed to the improvement of soil physical property.

This study was carried out to analyze the effect of the farm management and productivity increase of cabbages growing in the plastic house based on application of green manure crops such as silage corn, haussolgo (Sorghum bicolar L. Moench), hairy vetch, etc. According to the effect of green manure crop grown in summer season, the biomass amount of the silage corn was the highest; 7,630 kg per 10a, the next was haussolgo, 5,620 kg per 10a. In terms of the fertilizer ingredients, the first of forage soybean was 3.84% of nitrogen, whereas hairy vetch was 1.74% of phosphate and kalium, 4.74%. Productivity increase of cabbages was the highest in the haussolgo plot of which the yield of showed 10,090 kg per 10a and the farm household income would be worth 8,053 thousand won. By growing forage crops in the winter season, the biomass amount was the highest in the mixed sowing plot with rye (50%) and hairy vetch (50%) of 3,590 kg per 10a, whereas the productivity in the mixed seeding with rye (70%) and hairy vetch (30%) was highest, 6,249 kg per 10a and the farm household income would be worth 7,387 thousand won. Judging from these results, more practical on-farm research on applying different green manure crops as a basal fertilizer with cabbage in the plastic house should be considered to analyze the farm management and the farm household income at different sites.

This paper concerned about a study on the Algorithm Realization of Pattern Inspection for Color Printed Stamps. Up to date, the research of color data system in image processing have been studied widely. In this paper, color printed image using input signal in camera by median filtering technique is proposed to decrease noise and distortion in identical condition of input image, and consideration of color printed image characteristics five set of identical block of R, G, B value is extracted and then proposed the method of comparison with normal and abnormal printed color tone with trained learning of the Error Back-Propagation. The network structure induced this paper appropriate for a given problem and a good result is obtained by improve initial condition and adjust the number of hidden layer to solve the problem of real time process, learning and train. In the future, using a “C” language instead of “MATLAB”, a realization of algorithm for any kind of color printed image techniques would be improved and succeeded.
