Ⅰ. 서론
치아를 상실하게 되면 ‘제3의 치아’인 임플란트 치아를 시술하여, 자연치를 대치하게 된다. 임플란트란 본론에서 자세하게 다루겠지만 간단하게 이야기하자면 인공적으로 만들어진 치아를 잇몸 뼈 속에 심는 것이다. 이 때 잇몸 뼈가 부족하면 골 이식을 통해 이를 대체하는데, 본 설계

Founded as Korea’s first subway system provider on August 15, 1974 to provide mass transportation to the citizens of the Seoul Metropolitan area, Seoul Metro was the first local public enterprise to be established under Article 49 of the Local Public Enterprises a
Phosphor (Energy Converter)
Inorganic phosphor materials
“Classical” inorganic phosphors usually consist of a host lattice with activator ions doped into it in small concentrations, typically a few mole percent or less.
Host lattice & Activator ion
1st type : weak interaction (Ln3+)
2nd type: strong interaction ( Mn2+, Eu2+, Ce3+, Pb2+,Sb3+, Ce3+, MoO42-, NbO43-)
Activator (+ Sensit
First, Substrate is consists of a plastic or glass, a portion of the OLED is supportive.Anode is a role that make electron holes when current flows by removing electron. And the upper Conducting Layer is the place that Electron Holes is being created.Emissive Layer is the place accepting an electron from Cathode and produce light.
Emissive layer and conducting layer are called organic layer beca
