        Herein , the effect of changes in the organic loading rate in anaerobic digestion was evaluated. The experiment was carried out by a laboratory -scale semi-continuous stirred tank reactor, and feedstock was food-waste leached. The organic loading rate was increased by 0.5 kgVS/m3 in each phase from 1.0 kgVS/m3 to 4.0 kgVS/m3. At the end of the operation, to check the failure of the reactor, the organic loading rate was increased by 1.0 kgVS/m3 in each phase and reached 6.0 kgVS/m3. This shows that the biogas yield decreased as organic loading rate increased. Biogas production seemed to be unstable at 3.5–6.0 kgVS/m3. Moreover, biogas production dramatically fell to approximately 0 mL at 6.0 kgVS/m3, which was decided as the operation failure on the 16th day of the las tphase. The result of the reactor analysis shows that the cumulation of volatile fatty acid increased as the organic loading rate increased. This seems to occur due to the decreasein pH in the reactor and led to extinction of anaerobic bacteria, which were the biogas products. Although the buffer compound (alkalinity) could prevent the decline in pH, the concentration of alkalinity was found to be lacking at a high organic loading rate

        This study was carried out to investigate the economic value of organic rice production using gelatin ․ chitin microorganisms in eco-friendly complex, Gongsan, Naju city. The soil condition of experiment paddy field was Jeonbuk series and silt loam with a slightly poor drainage. Except for the high effective silicate, the chemical characteristics of soils used were included in the optimum range of paddy soils in Korea. In growth, plant length, tiller number, ear number, and ear length were observed to be higher in conventional paddy fields than organic paddy fields. However, number of grain per panicle and grain filling ratio (%) were higher in organic paddy fields than conventional paddy fields. Incidences of diseases and insect pests were slightly higher in the organic paddy fields. Water weevil, sheath blight, rice leaf roller and rice blast were more occurred in organic paddy field. On the other hand, false smut was higher occurred in conventional paddy field. There was a significant negative correlation between rice sheath blight and rice leaf roller, and rice yield. In the milled rice quality, the quality of organically cultivated milled rices was lower by the increase of broken rice than that of conventionally cultivated milled rices. The quality and palatability of rice were higher in organic cultivation with decreasing of protein content. Net income of conventionally and organically cultivated rice was 360,000 won/10a and 610,000 won/10a, respectively. Premium net income of the organically cultivated rice was 68%.

        This study was designed to compare re-epithelization rate/feature of conjunctival epithelial cell on amniotic membrane and anatomical difference between normal amniotic membrane and de-epithelial amniotic membrane. Human conjunctival tissue obtained while cataract operation were used in this study. Primary cultured human conjunctival epithelial cell and fibroblast were incubated on intact amniotic membrane and de-epithelialized amniotic membrane. After incubation for 3, 5 and 7 days, re-epithelization rate was analyzed using cell tracker and microscopic feature was examined using methylene blue and hematoxylin- eosin stain. For cell marker analysis, cytokeratin 14 and vimentin antibody immunofluorescence stain were used. Clearance rate of epithelial cells on amniotic membrane using trypsin was better than using 25% alcohol. The results of reepithelization rate using cell tracker, HaCaT, conjunctival firbroblast, and epithelial cell were rapidly incubated on deepithelialized amniotic membrane. Wound healing and re-epithelization were more rapidly induced on de-epithelialized amniotic membrane on permanent amniotic membrane graft.

        본 논문은 한국형 무경운 재배 토양에서 유기물 투입과 분할 관수가 고추 생육 및 수량 과 토양 화학성, 생물다양성에 미치는 영향을 구명하고자 추진하였다. 시험 후 토양에 화학 성을 조사한 결과 토양 pH는 5.6~6.2, 유기물 함량은 32~42 g ㎏-1, EC는 1.0~2.7 dS m-1, 치 환성 K은 0.08~0.24 cmol+ kg-1, Ca은 9.5~12.8 cmol+ kg-1, Mg은 2.7~3.2 cmol+ kg-1 수준이었 으며, 유효인산은 1,011~1,137 mg kg-1 수준이었다. 무처리에서 토양에 미소동물은 톡토기와 응애류 등 5종 54개체가 포획되었으나, 대두박을 투입한 처리는 9종 271개체가 포획되어 되었다. 토양환경의 지표가 되는 자연도 점수가 대두박 투입 처리는 11점으로 무 투입 5점 에 비하여 2배 정도 증가되었다. 대두박 투입은 무 투입에 비하여 고추의 수확과수의 감소 로 수량이 감소되는 경향이었다. 그러나 대두박 무 투입 조건에서 표준시비량의 33~66% 수준에서고추 수량은 증수되었으며 대두박 투입에서는 표준시비량의 33% 수준에서 증수 되었다. 2회 분할관수는 1회 전량관수에 비하여 고추의 수확 과수가 12.5~34.9% 증가되었 고, 수량은 13.5~34.4% 정도 증수되었다.
