토양 유기물과 인산 함량이 보통수준이고 규산함량이 낮은 산성의 식양질 논에서 유연탄회와 무연탄회를 각각 0, 50, 100, $150Mg\;ha^{-1}$ 시용하여 벼를 맥주보리 후작으로 재배한 결과, 석탄회의 토양개량효과가 지속되면서 벼 생육이 향상되었다. 벼 수량성은 무연탄회시용구 보다 유연탄회시용구에서 우수하였으며, 시용량 별로는 유연탄회 100 > 150 > 50 > 무연탄회 50 > 100 > 석탄회 무시용 > 무연탄회 $150Mg\;ha^{-1}$ 시용구 순으로 높았다. 그리고, 쌀 증수효과는 유연탄회시용구의 경우 6.2($50Mg\;ha^{-1}$ 시용구)~14.4%($100Mg\;ha^{-1}$ 시용구), 무연탄회시용구에서는 -0.6($150Mg\;ha^{-1}$ 시용구)~6.6%($50Mg\;ha^{-1}$ 시용구) 이었으며, 최고수량은 각각 $5.084Mg\;ha^{-1}$과 $4.738Mg\;ha^{-1}$이었다. 벼의 수확기 도복율은 유연탄회시용구에서는 20($50Mg\;ha^{-1}$ 시용구)~40%($150Mg\;ha^{-1}$ 시용구) 범위로 시용량이 많을수록 현저히 증가되었으나 무연탄회시용구에서는 1.3($150Mg\;ha^{-1}$ 시용구)~15%($50Mg\;ha^{-1}$ 시용구)로 유연탄회시용구와 반대경향을 보였다. 또한, 벼 증수효과가 우수하였던 유연탄회시용구에서는 수확기 토양의 pH와 유효인산, 치환성 양이온, 유효규산 등이 대조구 보다 양호한 수준을 보이므로써 석탄회시용 3년차에서도 작물의 생육에 대한 잔효가 기대되어졌다.

This study investigated the effect of kilning condfition on the diastatic power and activities of protease, $\alpha$-amylase, and $\beta$-amylase in rice malt. Common rice (Oryza sativa) was steeped at $30^{\circ}C$ for 50 h, germinated at $30^{\circ}C$ for 7 days, and kilned at $50^{\circ}C$ for 24 h. The moisture content and enzymatic activities were determined under various kilning times. As a result, the moisture content was reduced from 42.1 % to 3.9% after 24 h of kilning at $50^{\circ}C$. The protease activity of rice malt showed lower value than that of barley malt. All enzymatic activities were decreased during the kilning stage. Results indicated that after prolonged kilning at $50^{\circ}C$, the inactivation of hydrolytic enzymes might be occurred. Even though the amylolytic activity of malted rice showed low value, the rice malt shows the potential characteristics as ingredient for the brewing and cereal industries.

This study was conducted for 2 years at Chinju region to establish suitable seeding rate and fertilizing levels of nitrogen, phosphorous and potassium in spring-sown Jinyangbori. Heading and maturing were delayed by increasing fertilizers, especially nitrogen. Number of spikes per were secured by much seeding and increased application of nitrogen. One thousand grain weight reduced with increasing fertilization at any seeding rate. Relatively high harvest indices were observed with 12-10-4 at 10kg. 10a$^{-l}$ seeds planted, followed by 6-10-8 at 15 kgㆍ 10a$^{-1}$, and 6-10-4kgㆍ 10a$^{-l}$ at 20kg ㆍ 10a$^{-l}$ of N-P-K fertilizing combinations, respectively. There was no distinct differences on yield for various seeding rates in spring-sown barley. When seeding rate increased up to 15kgㆍ10a$^{-1}$, the positive effect of fertilizers was recognized as the function of balanced-application. It was possible to recommend 10kgㆍ10a$^{-1}$ as seeding rate and 6-5-4(N-P-K)kgㆍ10a$^{-1}$ as fertilizing combination in spring-time seeding considering low input and sustainable agriculture. There was no significant difference of protein content in grain by seeding rate. Increase of nitrogen fertilizer enhanced protein content in grain.

The purpose of this paper is to make it easy to reproduce the Pattern and sewing technique of men's coat in 18th century. which are modified in order to be made readily available in Korean theatre costume. The investigation was performed in three steps. 1st, The papers and records about development and change of men's coats were reviewed. End; The whole process of the way how to make a typical 18th century men's coats were sewn. 3rd ; The modification or revision into the more simplified pattern using by CAD system and sewing technique were suggested in detail. The size of the pattern in the original one, which we chose for this research, was generally small. with the side line being moved back a little. Moreover, arm movements were severely restricted because of the small arm-hole. The problems of original pattern were corrected by making both front and back pattern snug and side line being moved to the front, and making arm-hole wider. In the sewing technique, the simple way how to use of Padding, inter-linings and linings and to create the most noticeable figure of 18th century men's coat. This article may help theatre costume production in Korean performing art.

This study was carried out getting basic data for developing a new combine which is suitable for the cultivating situation in Korea or Southeast Asia. The relation of the amount of unthreshed grains and the axial displacement of crop in threshing process was attempted to formulate mathematically in a threshing chamber of axial-flow threshing unit. It was found that unthreshed grain is an exponetially-decaying functon of axial displacement of grains based on available data. Threshing experiments were performed to validate the mathematical model by changing various levels of pertinent variables for malting barley. Good correlation were obtained between the theoretical calculation and observed data for various test conditions, such as inclination, vane pitch, concave length, drum speed, feeding velocity, stream weight, moisture content. Therefore the model can be used for general purpose to find the amount of unthreshed grain if the mean rate of occurence of threshing of kernels(${\lambda}_{\tau}$) is properly calibrated considering some other operating conditions and crop conditions which are not involved in this analysis.

A stable method for strain distinction using viral RNA 1 structures analyses was developed and compared with the combined RT-PCR and RAPD methods. Seven out of 61 random primers were found to be polymorphic based on RAPD analysis resulting on the differentiation of the 33 BaYMV isolates into four distinct groups according to geographical districts. The first and largest group includes 13 isolate and consists mainly of two-rowed malting barley in Haenam area. The second group had ten collections from inland in west southern. The third group had seven isolates from west southern coastal region, where mainly six-rowed naked barley is cultivated. The last fourth group included three isolates from Gyungnam region in east southern area. Conclusively, RNA 1 analysis proved to be stable and efficient method for strain distinction for Korean BaYMV isolates. Further, results of pathogenicity and RNA 1 structure analyses revealed four groups BaYMV strains and were distributed all over Korea, represented by Naju, Haenam-okcheon, Iksan and Milyang.

In the forthcoming 21C, the development of cultural lives depends on that the water demand will increase or not. On the opposite site of that circumstance, many factors of the small watersheds will influence directly on how to cover the surface of watersheds with land use, no planning developing watersheds, and the rearrangement of small rivers. Especially as the extraordinary climatic Phenomena, exhaust of $CO_2$ and destruction of 03 layer, water resource and water foresting content of the small watersheds will be decreased by confusing on the malting a plan of water resources. For example, those are Typhoon Rusa in 2002, Typhoon Maemi in 2003 and heavy storms in 2004. This study area has three group and one of them having three small watersheds, total five small watersheds. That is, Sabukmyeon small watersheds in Chuncheon, Three small watersheds in Wonju(Jeoncheon, Jupocheon and Hasunamcheon), and Suipcheon in Yanggu-Gun which are located far away each other three group and different precipitation data. According to the land use such as dry field(or farm), rice field, forest land. building site and others in small watersheds, the amount of runoff will be impacted by monthly precipitation. The comparison between the runoff was getting from Kajiyama Formula and calculated runoff from multi-linear regressed equations by land use Percentage was performed with different precipitation data and different small watersheds. Its correlations which are estimated by coefficient of correlation will be accepted or not, as approached 1.0000 values. As the monthly water resources amount is estimated by multi-linear regressed equations with different precipitation data and different small watersheds having no gauging station, we make a plan in order to demand and supply the water quantity from small river watersheds during return periods.
