  • This study was wnducte to investigate the effects of treatment level and seasons of sluny hm bovine feces on the productivity of rye, N efficiency and improvement of soil fertility under the Korean climate condition. The results obtained fiom this study summarized as follows ; 1. The highest dry matter yield of rye was obtained in the partial fertilization of sluny in spring or autumn. There is no differences of dry matter yield between spring and autumn application. 2. With increasing the amount of slurry-N, the dry matter yield of rye was signigicantly increased up to 100Kg sluny Nha. As the level of slurry-N rises above about 100Kg N/ha, the maximal yield of dry matter was unchanged or declined. 3. As the level of sluny fertilization rises, the crude protein content of rye increases significantly. However the contents of crude protein was less affected by the application seasons. 4. The amount of nitrogen which produced 6om rye is dependent upon the level of slurry-N. The highest nitrogen yield of rye was obtained by the partial fertilization of sluny-N. 5. The season or amount of slurry treatments did not affect the organic matter content in soil. N-content in soil was the lowest by the partial fertilization of slurry in spring or autumn. However, N-content was increased with the higher level of sluny-N.

  • The characteristics of absorption and accumulation of inorganic germanium in Panax ginseng C. A. Meyer were examined. In 4-year-old P. ginseng, the germanium content of the field soil increased with increased amounts and frequencies of inorganic germanium application, while chemical components of the soil, such as available phosphate and exchangeable calcium, potassium, and magnesium, decreased with the increased inorganic germanium application. In the 4-year-old P. ginseng, the germanium content was highest in the rhizome and increased in the order of stem, leaf, lateral root, and main root, suggesting that inorganic germanium was absorbed from the root and translocated to the stem and leaf via the rhizome. As for changes in ginsenosides in 4-year-old P. ginseng rhizomes, the contents of ginsenosides $Rb_1$, $Rb_2$, Re, and Rf decreased as the germanium content in soil increased. Ginsenosides $Rb_1$, $Rb_2$, Rc, Re, and Rf in the main root also decreased with increasing germanium content in the main root. The results suggest that inorganic germanium treatment may increase organic germanium in harvested P. ginseng, thus enhancing the medicinal effi cacy of ginseng products.

  • The objective of this study is to promote alternative plans on the prejudiced and distorted parts in school textbooks in the aspect of multi-functionality of agriculture and rural community. This was done through analysis of the contents in 44 kinds of schoolbooks in Korean language (30 of elementary school, 12 of middle school and 2 of high school). This will lead to promote the understanding about the multi-functionality and form the proper value system related to agriculture and rural community for children and juveniles using schoolbooks. A content analysis which is a research tool to classify all contents of materials containing the properties to become the object of interest in a systematic way, was employed to examine to what extent the contents on agriculture and rural community were reflected in the textbooks for elementary school, middle school and high school. The content analysis was done in two categories, namely; application method and function view. Application method had four types of texts, cases, figures pictures, and activities, while function view emphasized the relevance for the multi-functionality of agriculture and rural community (i.e., function of environment preservation, function of rural scenery and rural traditional culture conservation, function of maintenance and development of local society, and function of food security). The results of application method in elementary school showed that the textbook of the second-year class having a large amount of figures pictures related to agriculture and rural community, had the highest frequency in all six grades. In the function view, the environment preservation function was most abundant among a variety of multi-functionalities. In middle school, the average frequency had shown a rapid decrease. However, the function of environment preservation in the function view and the texts by application method were most frequent. in the first-year class. In high school, however, any mention related to agriculture and rural community was not made, in spite of the fact that the ten parts of textbook contained a lot of contents with a reasonable level. Based on the results of content analysis, findings and recommendations by part in textbooks for elementary school, middle school and high school have been drawn, and several examples for the content development to be included in the textbooks were listed.

  • This experiment was conducted to elucidate the effects of foliar application of monopotassium phosphate on the acceleration of ind color and fruit quality of Satsuma mandarin cultivated in the plastic greenhouse. The 'a'value of peel chromaticity increased seasonably with the increasing frequency of foliar application of monopotassium phosphate, but became gradually irresponsive as the fruit approached to harvesting time. Glucose content increased with the number of foliar applications so did the fructose content. Content of reducing sugars tended to increase with the number of foliar applications by 0.32 to 0.41%.mL$^{-1}$ juice in treatment sof ive or more applications. Sucrose content increased gradually with the increasing number of foliar applications, but there was no significatn difference among treatments. Total sugar also increased with the increasing number of foliar applications Generally, the soluble solid level is considered to be representative of fruit quality. Sugar content increased with the number of foliar application up to 5 times in which sugar content increased by 0.93$^{\circ}$Bx as compared to the control. The fruit acidity of the treatment plots decreased as compared to that of the control, but there was no significant difference in fruit acidity among foliar application times.

  • A conventional environment adaptation for robust speech recognition is usually conducted using transform-based techniques. Here, we present a discriminative adaptation strategy based on a multi-condition-trained model, and propose a new method to provide universal application to a new environment using the environment's specific conditions. Experimental results show that a speech recognition system adapted using the proposed method works successfully for other conditions as well as for those of the new environment.

  • Food waste has recognized one of useful sources for potentially agricultural application to supply organic matter and nutrients in arable soil. However, there was little information on application of food waste compost related to the maturity and NaCl content in arable soil. This study evaluated the effect of food waste compost application on yield and fertility in soil under flooding and upland condition. The yields in rice and pepper cultivation decreased with increasing the rate of food waste compost application in soil (p<0.05). Maximum yields of rice ($49.0g\;plant^{-1}$) and pepper ($204g\;plant^{-1}$) were shown at 10 and $30Mg\;ha^{-1}$ of food waste compost application, respectively. The N, P, and K contents in grain and plant residues increased by the application of food waste compost, there was no difference on Na/K ratio in plant tissue among the treatments. Application of food waste compost resulted in the increase of pH, EC, TC, available P contents in soil after crop harvest, especially, which was shown the increase of the CEC and exchangeable sodium percentage (ESP) contents in irrespective of water condition. In conclusion, application of food waste compost in soil was effective on the supply of the organic matter and nutrient. However, it might need caution to apply food waste compost for sustainable productivity in arable soil because of potential Na accumulation.
