BiNem$^{(R)}$ displays have entered volume manufacturing in 2009. Applications range from e-labels to e-readers. We have developed 6-inch $960{\times}720$ pixels passive matrix BiNem prototypes achieving 40 % brightness and fluid user interface based on partial image / dynamic pointer addressing. Active-matrix addressing is proposed to provide even faster operation.

A hardware architecture is presented of a wavelet based multiple line addressing driving scheme for passive matrix displays using the FPGA (Field Programmable Gate Arrays), which will be integrated in the scalable video coding $architecture^{[1]}$. The incoming compressed video data stream will then directly be transformed to the required column voltages by the hardware architecture without the need of employing the video decompression.

Luminous efficacy of 6.0 lm/W has been realized by introducing a spatial positive column discharge together with delayed D pulses, shared sustain pulse voltage, and low sustain frequency drive. Also a high speed addressing of $0.25{\mu}s$ was achieved. The luminance was $157cd/m^2$, which is high enough for a 260-in. FHD display.

The relationship between driving voltage and the amount of wall charge in the address period of surface discharge type AC Plasma Display Panel has been investigated. The amount of wall charge on each electrode is obtained simultaneously from the current profiles after applying only one addressing discharge pulse. The wall charge $Q_y$ on the scan electrode Y is almost the sum of $Q_x$ on the address electrode X and $Q_z$ on the sustain electrode Z. The $Q_y$ increased with the driving voltage regardless of the kind of electrode, whereas the addressing $T_d$ decreased. The $Q_x$ and $Q_y$ are increased considerably by blocking voltage $V_z$, whereas $Q_x$ is decreased. The $V_z$ dependence of $Q_x$ $Q_y$ and ${\varrho}_z$ in addressing discharge was $-13{\times}10^{-2}$ (pc/$V_z$), and $60{\times}10^{-2}$ ($pc/V_z$) and $70{\times}10^{-2}(pc/V_z)$, respectively.

This short report introduces the general background why Brazil conference is being prepared and what topics would be undertaken and what goals are being taken into account. It overviews what differences from traditional telecommunication governance, internet governance has had in its historical development and how such differences had been formed from its technological differences and the regulatory policy shift from common carrier regulation to privatization. Moreover, the fact that open, voluntary, bottom-up, diverse stakeholder's participation had evolved throughout the historical development of the internet, had established the present multistakeholder governance model from technological standardization to addressing scheme policies. ICANN, which has governed internet addressing schemes since the earlier 2000s, had developed address policies including IANA function from Jon Postel and technical community's legacy management system into contract based formation between ICANN and gTLD, ccTLD registries. And it made dispute resolution policies responding to trademark disputes and resolved gTLD monopoly issue by introducing new TLD generation and the separation of registry and registar. However, there had been challenges on the legitimacy of ICANN due to its dependency on the Federal Government of the U.S. particularly in its oversight role over ICANN and IANA contract. WSIS raised up internet governance issues including addressing governance, and set up IGF as a discussion platform for multistakeholders to discuss and share all views on other internet related public policies. IGF's loose and non-binding discussion once frustrated governments and other stakeholders, but more focused discussion and visible outcomes have consolidated its unique role for internet governance discourses. Particularly, IGF addressed many emerging internet related issues like cybersecurity, privacy, net neuratlity, development related issues. WTPF of 2013, after WCIT debate on whether traditional telecommunication regulation could be applied to internet infrastructure, suggested other governance issues such as the transition to ipv6, IXP coordination etc. How to make sure the legitimacy of internet addressing governance and how and where other internet related public policies could be undertaken are fundamental tasks for internet governance. Brazil conference, which has been motivated by the breakdown of trust in internet governance from NSA mass surveillance revealed by Snowden, faces these questions and try to make consensus on principles, institutions and roadmap for internet governance in multistakeholder participation way.

현재 우리나라의 인만 서장우편 물량은 매년 증가하고 있는 추세이며 특히 월말이나 연말에 집중화되는 계절성과 순환성의 특성을 보인다. 그러나 우편물량의 증가와 월말 또는 연말에 집중화되는 현상에 적절히 대응하지 못하고 있으며, 집배원의 인력 부족으로 서비스의 질적 저하와 업무 부하량 증가 등의 문제가 더욱 가시화되어 가고 있다. 이러한 상황에서 신속한 우편물 처리와 집배원의 업무 경감 등을 위해 배달우편물 순로구분 시스템, 주소정보 시스템 도입 등의 노력이 시도되고 있으나. 일반 소비자 또는 다량 우편물 발송업체 등의 주소 기재 방식이 일정하지 않고 표현 방법이 다양하여 자동화 기계 및 집배원 업무효율의 저하가 예상되고 있는 실정이다 따라서 본 논문에서는 우편물에 기입하는 주소의 표기 표준화를 통해 주소인식률과 집배원의 배달 구분 업무 효율성을 향상시키고자 한다. 먼저 국내 우편주소 체계와 정보 구조를 살펴보고, 각각의 문제점을 파악하여 표준화 시 고려할 요소들을 표기 내용을 중심으로 정리하였다. 그리고 자동주소인식을 위해 다양한 형식의 결정을 위해 고려사항들을 제시하였다.

Recently, the demand for high definition TV is being increased by beginning of the digital broadcasting. The higher resolution of PDP is, the longer addressing time become, then, the sustain period for display image decreases. Because of the reason, dual-scan method which synchronously write information of an image on top and bottom of the screen is used for the high definition PDP. However, as the price competition of PDP becomes severe, we can`t avoid turning to a single-scan method which uses only a half of an expensive address IC. Accordingly, the sustain period becomes much shorter than prior method. In case of XGA level, it is impossible to display, eventually. In this paper, we are going to prove usefulness by realizing negative reset waveform and the driving circuit for high speed addressing.

The relationships between driving voltage and the wall charge distribution in the address period of surface discharge type AC Plasma Display Panel have been investigated. The quantity of wall charge on each electrode are detected simultaneously from the electrode current after applying only one addressing discharge pulse. The wall charge Qy on the scan electrode Y is nearly the sum of Qx on the address electrode X and Qz on the sustain electrode Z. The Qy increased with the driving voltage regardless of the kind of electrode, whereas the address time Td decreased, Qz and Qy are increased considerably with the blocking voltage Vz, whereas Qx is decreased. The increase rate of Qx, Qy and Qz for increase in Vz was $-13{\times}10^{-2}$ (pc/Vz), and $60{\times}10^{-2}$ (pc/Vz) and $70{\times}10^{-2}$(pc/Vz), respectively.

본 논문에서 우리는 PAL-공간변조기를 사용한 Two-pupil 광학 스캐닝 기술에 의하여 실시간 JTC 상관 광 시스템을 수행할 수 있음을 보여주고자 한다. 광학적 addressing(Optical addressing)은 빛에 민감한 $\alpha$-Si 층, 즉 액체 크리스털을 따라 전기장을 조절하는 얍은 층에 의하여 성취되었다. 제안된 기술은 광학적 Twin-pupil 헤테로다인 스캐닝(heterodyne scanning)에 근거하고 있으며, 이 기법은 Fourier 평면에 위치한 광 공간변조기와는 독립적으로 작용한다. 우리는 본 기술의 이론적 근거를 개발하고 목표이미지와 참조이미지 사이의 상관관계를 실험적으로 평가함으로서 본 기술의 성능을 평가하였다.

현재 인터넷 아키텍처가 가지고 있는 가장 큰 문제는 routing과 addressing의 핵심으로 사용되는 IP 주소의 의미의 중복 (overloading semantics)이다. 즉 IP 주소는 라우팅을 위한 정보 (how), 단말의 위치 정보 (where), 그리고 이 외에 전송 계층 상위에서 사용되는 단말의 식별자 정보(who)로 사용되며, 이 의미 중복은 결국 global routing의 scalability문제를 발생시키게 된다. 즉 이러한 IP 주소의 의미 중복을 분리한다면 멀티호밍, Traffic engineering, 그리고 renumbering 등을 scalability에 영향을 주지 않고 이것들을 지원할 수 있게 되는 것이다. IETF는 이러한 라우팅과 어드레싱의 확장성 문제를 해결하기 위하여 68차 IETF 회의에서 ROAP (ROuing and Addressing Problem) BoF (Birds of a Feather) 회의를 공식적으로 개최 하였으며, 이를 통해 결정된 사항은 새로운 인터넷 아키텍처를 설계하기 위해 식별자(Identifier)와 위치정보(locator)를 분리하는 구조(ID/Loc 분리) 또는 다중 계층의 위치정보 획득이 가능한 구조(Multi-level locator design)로의 새로운 아키텍처를 만드는 것이다. 이 작업은 ROPA BoF회의 이후 IRTF의 RRG (Routing Research Group)에서 계속적으로 진행되고 있으며, 현재 관련 많은 솔루션들이 나온 상황이다. 본 논문은 이러한 ROAP에 관한 기본적인 설명과 함께, 문제점 그리고 논의되고 있는 솔루션들의 분류, 목적, 그리고 공통 이슈들에 대한 최근 동향을 설명한다.
