The purpose of this study is to examine the functions and features of SearchWorks developed as the Next Generation Library Catalog by Stanford University Libraries. It was designed to fully represent the needs and search behaviors of users, with Blacklight, an open source software. Its main features are not different from those standard functions supplied by other commercial packages of Next Generation Library Catalogs, and its continuing improvement and changes, including the addition and expansion of more useful functions and the removal of unnecessary ones, have been observed since the introduction of a beta version in 2010.

This paper presents a quality-of-service-enabled next generation local area network architecture which can provide efficiently convergence services over the Internet protocol. The basic concept of the architecture is to combine such three principle technologies as programmable switched network quality-of-service resource management and Internet protocol based network convergence. We discuss system entities and technologies development, which constitute the proposed network. The architecture of the network is then described. Implementation of systems verifies the proposed technologies. The network as a next generation local area network can provide quality-of-service-enabled real-time communication services as well as existing data traffic, and the open programmable interface can facilitates to adopt cost-effectively emerging new services or functionalities.

This study proposes to identify digital library services applying cutting-edge technologies, and attempt to investigate the applicability of these technologies and services to domestic libraries. To this end, we reviewed main research which discusses next generation digital libraries, and examined thoroughly main technologies which can be applied to future libraries. As a result, the core technologies, concepts, and tools of the next generation of digital library are: cloud services, space for infinite creating (makerspace), big data, augmented reality, context-aware technologies, Google-glass, a revolutionary display technology, open linked-content-offering method, and so on. Specific cases of libraries already utilizing these technologies are also discussed.

This paper studies a system design of testifying next generation convergence network. Next generation convergence network includes such elements as not only various gateway systems interworking with conventional PSTN(Public Switched Telephone Network) but also various protocols communicating between gateway systems and softswitches or gateway controllers. Discussed are an effective system solution to verify functionalities and performance of protocols professing. From such discussion, the study identifies functional blocks and operational flows required for establishing a test system, and then with a basis of these proposes a system architecture. Finally this paper presents system design results and its implemented functional details.

In this paper, the definition and overview of digital health care that has emerged recently, core technology, and We would like to propose a plan to establish a next-generation information protection system that can protect digital healthcare devices and data from cyber attacks. Various vulnerabilities exist for digital healthcare devices and data, and cyber attacks are possible for those vulnerabilities. Through an attack on digital health care devices and information and communication networks, it can directly adversely affect human life and health, Since digital healthcare data contains sensitive and personal information, it is essential to safely protect it from cyber attacks. In the case of this proposal, for continuous safe management of data and cyber attacks on equipment and communication networks for digital health devices, It is expected to be able to respond more effectively and continuously through the establishment of the next-generation information protection system.

Reflective semiconductor optical amplifiers(R-SOAs) were designed with high gain, wide optical bandwidth, high thermal reliability and wide modulation bandwidth in TO-can package for the transmitter of wavelength division multiplexed-passive optical network(WDM-PON) application. Double trench structure and current block layer were introduced in designing the active layer of R-SOA to enable high speed modulation. The injection power requirement and the viable temperature range of WDM-PON system are experimentally analysed in based on Amplified Spontaneous Emission(ASE)-injected R-SOAs. The effect of the different injection spectrum in the gain-saturated R-SOA was experimentally characterized based on the measurements of excessive intensity noise, Q factor, and BER. The proposed spectral pre-composition method reduces the bandwidth of injection source below the AWG bandwidth and thereby avoids spectrum distortion impeding the intensity noise reduction originated from the amplitude squeezing.

At recent, the Internet is evolving into the directions which is capable of incorporating stream-type services such as voice and video services due to the remarkable growth of WWW service and the development of new multimedia application services. However, the existing Internet can only support a best-effort delivery model and thus it is difficult to satisfy these requirements as well as to provide the QoS beyond a certain degree. Accordingly, it is imperative to develop QoS-based routing algorithm in order to allow flexible routing by the Internet user's QoS demand and to be applied into wide area networks. In this paper, we presented new routing algorithms for next generation Internet services and made performance evaluations. The proposed algorithms allow the routing by the user's QoS demand level in order to provide the diverse Internet application services based on ATM network environment that is expected to play a role as an infrastructure of next Generation Internet Services.

Internet의 확대와 망의 진화에 따라 현 통신 방식은 기존 회선 교환 방식에서 패킷 교환 방식으로 진화를 한다. NGN(Next Generation Network)이란 정확하게 정의를 내리기는 어렵지만, 개념적으로는 현존하는 모든 서비스(Voice, Data, Video 등)들과 미래에 나타날 멀티 서비스를 통합하여 수용할 수 있는 패킷 기반의 통신망을 의미한다. 이러한 개념은 망의 통합을 목적으로 하는 NGcN(Next Generation Convergence Network, 이하 NGcN)로 진화하고 있다. 하지만, 진정한 의미의 NGcN은 Legacy 회선 교환 방식(include Wireless Network)과 패킷 교환 방식의 모든 망 사용자에게 동일한 서비스를 제공하는 것이며, 이것은 Convergence Service라는 개념으로 정리를 할 수 있다. 본 논문에서는 이와 같은 접근을 Next Generation Convergence Service(이하 NGcS)로 정의를 한다. 논문에서는 NGcS 구축을 위해 지능망 서비스와 연계하여 접근을 할 것이며, INAP(Intelligent Network Application Protocol), WIN(Wireless Intelligent Network) 및 CAP(CAMEL Application Part) 등의 제어방식에 근거한다. 이러한 방식들에 대한 연동에 대해 논하며, NGcS 구축을 위한 Service Switching Function 설계 방법과 서비스를 트리거(Trigger)하기 위한 방법에 대해 논한다.
