터치스크린 기반의 스마트폰의 경우 작고 좁은 입력 시스템을 가지고 있다. 또한 키들 간의 물리적인 경계가 없어 인접어가 잘못 입력 되는 터치 오류가 자주 발생한다. 본 논문은 스마트폰에서 키보드의 인접키가 잘못 터치 되어 발생하는 오류를 정정하고, 개인화 된 사용자의 입력 빈도에 기반한 입력어 추천 시스템인 Klice에 대하여 설명하고 있으며 기본 입력에 대비한 성능평가 결과도 소개한다. Klice는 현재 Apple사의 AppStore에서 다운 받을 수 있다.

본 연구에서는 터치 스크린을 사용하는 스마트폰에서 보다 편리하고 효율적으로 한글을 입력할 수 있는 방식에 대하여 제안하고자 한다. 기존의 2벌식 자판은 화면의 크기가 제한적인 모바일 환경에 적합하지 않으며, 터치스크린 방식은 미세한 접촉으로도 글자가 입력되기 때문에 사용자가 의도하지 않은 오/탈자가 빈번하게 발생한다. 본 연구에서 제시하는 입력 방식은 한글의 제자원리를 이용하여 자음 입력 후에 스케치를 통해 모음 입력을 부드럽게 이어가는 방식을 제안한다. 제안 연구는 사용자가 제한된 화면 영역을 효율적으로 사용하여 향상된 속도로 한글을 입력할 수 있게 도와주고, 원하지 않는 오/탈자의 발생빈도를 줄이는 효과를 가지고 있다.

Smart education in the information window, type talent in modern society is changing as talented smart shoes, smart automation creative talent through education, training can be called education revolution. In other words, the advent of smart devices, such as knowledge and information and to actively growing individual customized training paradigm change in the way education and training to reflect this approach. Therefore, in this paper, a smart learning environment based technologies for implementing the system was designed to be the next generation of cloud computing and N screen-based smart education system was studied. From this, educational functions and features in a smart media environment, based on the analysis of the utilization of a smart education system, which maximizes the system design were studied.

인터넷이 방송에 활용된 이후 사용자는 플랫폼과 콘텐츠에 대하여 더 많은 선택권을 가지게 되었고 이러한 경향은 스마트 TV와 N-스크린 방송 도입 이후 더욱 확고해졌다. 방송사는 이러한 변화에 발맞추어 플랫폼을 확장하고 다양한 서비스를 제공하기 시작했다. 많은 사용자들과 많은 콘텐츠를 바탕으로 서비스를 제공하기 위하여 방송사들은 데이터 분석을 서비스에 도입하기 시작하였고 여러 가지 지능적인 콘텐츠 서비스들을 고안하였다. KBS 기술연구소에서 진행한 관련 연구들의 흐름을 소개함으로써 방송 환경에서의 지능적 콘텐츠 서비스 흐름을 파악하고자 한다. 콘텐츠 추천을 시작으로 N-스크린 부가 서비스 활용, 데이터 자동 인식 연구까지의 동향을 소개한다.

Carbon solubility on the paste deposition methods in the carbon-doped TiZrN coating was investigated in terms of lattice distortion and atomic concentration. After depositing the carbon paste by the dip coating, spin coating and screen printing, the laser was ablated to form the carbon gradient layer. Thickness and the concentration of doped carbon depended on the paste deposition method. Crystal structure analysis indicated that more lattice distortion occurred when coating layers were doped with spin coating and screen printing than when coating layers were doped with dip coating. The XPS depth profile showed that the thickness of carbon gradient layer by dip coating was about 30 nm, spin coating and screen printing are approximately 100 nm, formed more gradient layer. The hardness before laser carburization was about 30 GPa, and the hardness of 31 GPa with dip coating and 37 GPa with spin coating and screen printing. It was indicated that paste deposition methods for laser carburization contributed to lattice distortion and gradient layer.

The mobile devices and cloud computing technology introduced new content services such as N-Screen service. The DRM techniques have been developed to support interoperability and multi-platform for new environment of content service. Nevertheless, it is still inconvenient for the consumers to purchase a new DRM-supported device or to migrate some purchased contents into new device due to the change of the subscription of service. Therefore, in this paper, cloud-based DRM model which is referred as DRMaaS (DRM-as-a-Service) model, is proposed to allow the consumer to freely use and move some DRM-protected contents in various smart devices regardless of subscription of service.

As the subscribers of the digital cable and IPTV broadcasting are increasing, the VOD service has established a solid foothold as a profit model of the broadcasting industries. And what's more, the VOD service is emerging as a key application of the N-screen technologies. In the circumstance, broadcasting companies are trying to provide mobile services to improve the satisfaction of their VOD services usage. The paper introduces a VOD mobile app (of a domestic digital cable broadcasting), which includes the functions of promoting the VOD programs printed on a VOD guide book, directly transmitting the information (e.g., book-marking, remote-control signals) generated by the VOD mobile app to a set-top box, and watching the video contents stored in the mobile device on TV.
