The Soysauce wastewater removal characteristics of submerged biofilters filled with two filter media respectively were experimentally examined with constant temperature, pH value and variable BOD loading and recirculation ratio. The decreasing order of BOD removal is Netring(random plastic media), cubic wire meshes(plastic module). This is mainly due to the media characteristics such as void ratio, specific surface area and media shapes. The BOD removal ratio decreases with increasing $BOD_5$/ volumetric loading rate, and the loading rate for the BOD removal over 85% is lower than 1.5kg$BOD_5$ 5/$m^3$d for the plastic media of Netring and cubic wire meshes. The $BOD_5$ removal rate increases with the recirculation ratio, but the rate of increase become smaller as the recirculation ratio increases over 20. When $BOD_5$ volumetric loading is 1.5kg$BOD_5$/$m^3$d, the required recirculation ratio to obtain 85% BOD$_{5}$ removal is about 20 for Netring and it was about 30 for cubic wire meshes.s.

본 논문에서는 기존의 영상 및 동영상 편집 툴을 사용하여 2D 동영상을 3D 입체영상으로 변환하는 절차를 분석하고, 변환 과정에서 나타나는 비효율적 요소 및 자동화 가능 요소 등을 분류한다. 또한, 기존의 3D 입체영상 변환 도구의 종류 및 한계점을 분석하고, 분석 내용을 기반으로 3D 입체 영상 변환 전용도구의 필수 기능을 설계한다.
