본 논문은 HTML5의 새로운 표준인 웹소켓(WebSocket)을 이용하여 구현한 실시간 커뮤니케이션 시스템을 소개한다. 본 논문에서 구현한 시스템은 PC의 브라우저와 모바일 디바이스 모두를 통해 접근이 가능하다. 본 논문에서 구현한 실시간 커뮤니케이션 서비스 시스템은 이벤트 기반의 비동기 방식을 채택함으로써, 클라이언트가 리로드(reload)하지 않더라도 필요한 정보를 빠르게 제공한다. PC의 브라우저가 접근하는 부분은 Node.js를 사용하여 구현하였으며, 모바일 디바이스가 접근하는 부분은 PhoneGap 플랫폼을 사용하여 구현하였다. 본 논문에서는 시스템의 전체 구조와 관련 기술을 설명하고, 구체적인 구현 코드의 일부를 제시하며, 추후 확장 가능성과 비전을 제시한다.

Reports have it that horizontal and vertical loss of the ridge happens during 6 months after tooth extraction. So valuable ridge preservation techniques are often necessary in the maxillary anterior areas. Maintaining and/or increasing blood supply and stability is essential to graft survival. The objective of this study was to determine the effect on extraction socket seal of pedicle subepithelial connective tissue graft with tunneling on maxillary esthetic zone through healing state for 8 weeks.

We propose a high speed data communication method for motor drive systems with fast control cycle in order to collect state variables of motor control without degrading control performance. Ethernet is chosen for communication device, and multi-core DSP architecture is exploited for communication processing load distribution. The communication program including network protocol stack and motor control program are assigned to two separate cores, and data between two cores are exchanged using interrupt-based inter-process communication mechanism, which enables to achieve a high-speed communication performance without degrading the motor control performance. The performance of developed communication method is demonstrated by real experiments using TCP, UDP and Raw Socket protocols in an experimental setup consisting of TI's TMS320F28388D motor control card and MS Windows PC.
