We propose a novel digital driving method for AM-OLED (Active Matrix-Organic Light Emitting Diode) display. Proposed method modulates $V_{DD}$ so that luminance may be weighted in accordance with the bit significance. We can increase the minimum emission time or slower scan circuits are applicable by using proposed method.

Every protein can be characterized by either a distinct motif or a combination of motifs. Nevertheless, little is known about the relationships among (more than two) the motifs. Some of the proteins in the world are share motifs for evolutional or other biological benefits - they can save energy, time and resource for controlling and managing a variety of proteins. In some cases of motifs, the tendency is quite common and they can act the 'hub' motif of a network of the motif associations. The hubs are structurally and functionally important in themselves and also important in disease-related mutations. They will be highly resistant mutation to conserve their functions. But, in case of the a rare mutation, mutations on the position of hub can more easily cause fatal diseases.

The linguistic characteristics of a sign language provide an important clue for an automatic construction of its expression from a given natural language sentence. For such characterization, we focus on the identification of elided constituents, the mapping of property-changing information into spatio-temporal dimension, and the need for rearranging the order of component information for enhanced quality of delivery. We use our characterization to implement a system that converts sentences in Korean into corresponding expressions in the Korean Sign Language.

프로젝션 디스플레이 시스템(PDS)을 사용한 Advanced Paper Document (APD)는 오프라인 문서와 온라인 문서의 장점을 모두 가지고 있다. PDS는 가상의 물체를 실제 세계에 공간적으로 연결하여 줌으로써 사용자에게 더욱 풍부한 정보를 제공할 수 있다. 본 논문은 단순하게 오프라인 문서에 대한 온라인 정보를 보여주는 APD의 기능을 확장한, 사용자가 직접 오프라인 문서에 온라인 정보들을 삽입, 삭제, 수정할 수 있는 Advanced Documents Authoring Tool (ADAT)을 제안한다. ADAT는 PDS 위에 놓여진 실제의 오프라인 문서와 가상의 온라인 정보를 직관적으로 연결해준다. 사용자가 전자펜을 통하여 문서를 선택하면, 작업 공간 위쪽에 설치된 카메라를 통하여 문서의 영상을 입력받고, 해당 문서의 기존에 저장되어있는 정보를 검색한 후, 프로젝터를 통하여 문서 위에 투영해줌으로써, 사용자에게 온라인 정보를 제공한다.

Copper ink has been prepared by mixing copper(II) formate and 2-ethyl-1-hexylammonium bicarbonate (EHABC) to overcome some weak points such as aggregation and degradation of copper nano-type ink. Ink was coated on glass substrate and calcined at $110^{\circ}C$ to $150^{\circ}C$ to generate electrically conductive copper film under two different atmospheres such as nitrogen gas and gaseous mixture of formic acid and methanol. The lowest resistivity of $1.88{\mu}{\Omega}{\cdot}cm$ of copper film was obtained at $150^{\circ}C$ in gaseous formic acid condition. The long-term resistivity shows to increase from $1.88{\mu}{\Omega}{\cdot}cm$ to $2.61{\mu}{\Omega}{\cdot}cm$ after one month.

최근 정보추출에 대한 중요성이 점차 증가하면서 정보추출에서 필요로 하는 Named Entity와 Coreference, Information Extraction, Information Retrieval의 소개와 한국어에 대해 적용시키기 위한 정의와 방법을 제시한다. 또한, 대량의 문서에 대한 태깅을 효율적으로 수행할 수 있도록 Named Entity와 Coreference 태깅을 쉽게 할 수 있는 NE-CO 태깅 도구를 개발하였다. 이 태깅 도구를 이용하여 시험적으로 경제, 공연, 여행 분야의 300문서에 대한 말뭉치를 구축하였으며, 이 말뭉치는 한국어 정보추출 시스템을 개발하는데 기초 자료로서 활용될 예정이다.

Alignments of photo-reactive mesogen were induced using bare glass substrates without a polymer alignment layer. It was found by using polarized FTIR spectroscopy, polarized microscopy, and birefringence measurement experiments that the reactive mesogen could be aligned along the rubbing direction although the glass substrate without an alignment layer was used. The induction mechanism of the rubbed bare glass is ascribed to that polymers from rubbing clothes are coated on the glass substrate along the rubbing direction and lead the alignment of liquid crystals through intermolecular interactions.
