인터넷상에서 무분별한 주민등록번호 사용을 최소화하여 명의도용 등의 피해를 방지하기 위하여 2005년부터 아이핀을 개발하여 보급중이며, 특히 아이핀 서비스를 대폭 개선한 아이핀 2.0이후에는 도입하는 웹사이트와 이용자가 급증하는 상황이다. 본 논문에서는 아이핀이 단순히 웹사이트 회원가입시 실명확인을 대체하는 수단을 넘어 인터넷상에서 국민 전체가 안전하고 편리하게 사용할 수 있는 디지털 ID가 되기 위한 발전 전략을 제시하고자 한다.

This study is a preview of characteristics of (1st/2nd) rubber suspension parts in low temperature, it will be researched before Trans Korean Railway and continental railway network connection. Rubber material characteristics are different to steel materials. Behavior of rubber material shows large deformation in hyper-elastic region. Moreover, added dashpot and low temperature condition shows various non-linear characteristics.

We have applied self-assembled monolayer to make high performance and stable OTFT on the organic gate dielectric. The ${\beta}$-phenethyltrichlorosilane (SAM) was coated on the organic gate dielectric and then active layer was printed. Significant improvements in on-currents and threshold voltage shift were achieved for the SAM treated devices compared to device without SAM.

The goal of this paper is to analyze the relationship between pedagogy and the emergence of contemporary Korean architecture after the 1990s. For this purpose, the paper deals with the education and work of two important contemporary Korean architects, Kim Seung Hoy and Choi Wook. Kim and Choi were part of a group of young architects that went abroad in the 1980s to study at the centers of architectural education in Europe and the United States. Through their education and work, the paper discusses the relationship among education, history, and design practice in architecture. During their studies at Michigan University and IUAV in Venice, they were commonly influenced by Colin Rowe through their studios. In the case of Kim Seung Hoy, he was introduced to the Beaux Arts logic of the analytique and esquisse through the teaching of Steven Hurrt, a disciple of Colin Rowe. Choi Wook took studios that involved formal analysis and comparison of Palladio and Le Corbusier. The paper further analyzes their works in Korea by employing the concepts of fragments and systems, ignorance and knowledge. The paper concludes that, in Korean contemporary architecture, fragments and systems, ignorance and knowledge, lie in the middle of ongoing creative process that must distinguished from the West, where architectural history provides an established tradition of systematic knowledge.

We obtained high performance of n-type organic thin film transistors (OTFTs) using a solution process. N, N' bis-(octyl-)-dicyanoperylene-3,4:9,10-bis(dicarboximide) (PDI-$8CN_2$) in ambient air. Low work function interlayer on source/drain is needed to enhance the electron injection to low LUMO level of n-type organic semiconductor. By using self-assembled monolayer (SAM) the field-effect mobility of 0.33 $cm^2$/Vs was achieved.

Achieving an aesthetic implant-supported restoration in the single tooth missing case can be challenging when the implant site is in e anterior region. The objective of this report is to focus on presurgical evaluation of implant site and systematic development of related prosthetic modalities. An accurate diagnostic evaluation, a systematically developed pesurgical plan, and knowledge and clinical skill of the various related therapeutic modalities are indispensible. Collection of patient's information, appropriate abutment selection, soft tissue contour, implant axis, and occlusion need to be discussed for aesthetic clinical outcome. For aesthetic restoration, such as surgical guide stent for precise implant positioning customized provisional restoration for development of optimal periimplant soft tissue contours, and fabrication customized abutment (mesiostructure) for veriable emergence profile, are recommended.
