Objectives: Recently, high attention has been drawn towards evidence based medicine(EBM). However, there is little follow study after Park's analysis research (2002) in the journal of oriental gynecology. Therefore, there is a need to conduct analyzed research on the topic, due to the increasing interest about EBM. Methods: To analyze the treatises of the journal of oriental gynecology, we examined 56 journals published from 1987 to 2010. we followed the way of Park, classifying treatises into bibliographic, experimental and clinical categories. Results: Analytic research, as a part of clinical treatises, increased rapidly from 2001. As a result, it took 53.3% of whole study in general after 2002 and it reached up to 70.0% in 2004. Most part of clinical treatises until 2002 was about case report of patients, but the amount of clinical trial started to increase since 2003. Case report and case series showed dramatic increase after 2001, and clinical trial started to increase after 2003. As a result, 43.8% of the analyzed research was due to clinical trial by 2009. Conclusions: On the base of this research, quality evaluation of clinical treatises using guality assessment tool is needed for EBM in the part of oriental obstetrics & gynecology.

Rice yield and grain guality were investigated with treatments of silicate fertilizer, straw compost and NPK fertilizer in the paddy soil of silty clay loam from 1975 to 2001. Rice yield of the treatments of silicate fertilizer. $1,500kg\;ha^{-1}$ and straw compost $10,00kg\;ha^{-1}$ were increased by 15%, 10%, respectively, for 27years average yield in comparison with NPK plot. In the plots of NPK+silicate fertilizer $1,500kg\;ha^{-1}$, NPK+silicate fertilizer $2,500kg\;ha^{-1}$, taste value(Toyo instrument) of cooked rice and quality assessment were higher than those in NPK control plot and NPK+straw compost $10,000kg\;ha^{-1}$ plot, but the contents of crude protein, amylose of milled rice grain were lower than those in other treated plots. Nitrogen and phosphorous contents of rice plant were lower, but $SiO_2$ content were higher in the treatment of silicate ferti lizer 1,500, $2,500kg\;ha^{-1}$ than straw compost $10,000kg\;ha^{-1}$ plot. Rice quality assessment was positively correlated with taste value, but it was negatively correlated with crude protein and amylose content of milled rice grain. Ratios of Mg/N, $Mg/N{\cdot}K_2O$, $SiO_2/N$, $SiO_2/P_2O_5$ and $SiO_2/K_2O$ were positively correlated with taste value and quality assessment of rice grain, but negatively correlated with crude protein, amylose and fatty acid content. In soil chemical characteristics related with rice quality after experiment in 2001, soil pH and $SiO_2$ content were positively correlated with taste value and quality assessment of rice grain, but contents of soil $P_2O_5$, ex-K were negatively correlated with them.
