Assembling Synthesis of Barium Chromate Nano-superstructures Using Eggshell Membrane as Template
Jinku Liu,Qingsheng Wu,Yaping Ding,Yu Yi 대한화학회 2004 Bulletin of the Korean Chemical Society Vol.25 No.12
The branch-like, feather-like BaCrO4 nano-superstructures were synthesized with bioactive eggshell membrane as directing and assembly template. Studies on the two products revealed that they formed through the self-assembly of nanoparticles, and that the optical properties of the products were different from BaCrO4 bulk materials.

Accumulation of tissue macrophages is a significant cha-racteristic of disease-associated chronic inflammation, and facilitates the progression of disease pathology. However, the functional roles of these bone marrow-derived macrophages (BMDMs) in aging are unclear. Here, we identified age-dependent macrophage accumulation in the bone marrow, showing that aging significantly increases the number of M1 macrophages and impairs polarization of BMDMs. We found that age-related dysregulation of BMDMs is associated with abnormal overexpression of the anti-inflammatory interleukin-10. BMDM dysregulation in aging impairs the expression levels of pro-inflammatory cytokines and genes involved in B-cell maturation and activation. Phagocytosis of apoptotic Jurkat cells by BMDMs was reduced because of low expression of phagocytic receptor CD14, indicating that increased apoptotic cells may result from defective phagocytosis of apoptotic cells in the BM of aged mice. Therefore, CD14 may represent a promising target for preventing BMDM dysregulation, and macrophage accumulation may provide diagnostic and thera-peutic clues. [BMB Reports 2017; 50(1): 43-48]

교실 현대화 또는 교과교실 지원 사업에 의하여 현재 대부분의 학교는 2D 형 LCD 타입의 전자칠판을 설치하여 운용하고 있으며, 현재는 3D 전자칠판의 도입이 활성화되고 있는 시기이다. 본 연구는 상호응답형 3D 전자칠판에 대한 연구이다. 상호응답형 3D 전자칠판의 구성은 영상을 제어를 위한 AD보드, 3D 변환을 위한 3D변환 포맷터, 해상도 제어를 위한 FRC보드로 결합되며, 상호응답형 전자칠판을 구현하기위해 {x,y,z} 좌표 축출을 위한 전자팬 및 양안 카메라 기술을 적용했다. 또한 실시간 3D 판서 운용을 위한 3D 판서소프트웨어에 대한 구현 방법과 운용 구성에 대하여 연구했다.
