This research addresses global status of Korean media firms and their future directions. Mapping of major international media firms all over the world is used in order to explain global status fully. In the four categories that classified media firms using Forbes Global 2000 mapping, all Korean media firms are included in the fourth group, which is the weakest in terms of global competitiveness. Therefore, it is essential to trace appropriate global strategy from the media industry value chain that has competence. This paper finds out that Korea has advantage in the contents, terminal, and next generation networks. That means alliance strategies of contents-terminal-next generation network have advantage to evolve into global media firms. Moreover, Korean media companies should adopt selection and concentration strategy in terms of geographical expansion. As Korea's broadcasting and game contents are already popular in Asian and Latin American regions, they would better to enter the emerging markets. In so doing, terrestrial broadcasters and game service providers should lead the way.

Collaborative Digital Reference Service( CDRS) has spread worldwide as a tool of obtaining high-quality information in knowledge information society KISTI formed CDRS collaboration model called Question포인트+ with 4 institutions in Korea. In Question포인트+ which is also linked to the Global Network, the domestic and oversea information specialists answer a variety of questions in response of the requests of users on the web. The implementation of Question포인트+ is significant as the first domestic CDRS collaboration model, and contribute to management, dissemination, and activation of CDRS in Korea.

As the cultural industry might be regarded as the most intimate industry to the general public, it is relatively easy to be widely accepted. With the development of the internet, not only people in various countries have been closely connected, but production networks around the world might also be connected with each other. This article will use data and case studies to clarify how global production networks operate in the development of the cultural industry. By taking the relatively novel point of contact of connection between global production networks and the development of the cultural industry, it summarizes the development models of the film, television and music sectors in the Korean cultural industries. The study found that the development model of the film, television and music industry from the 1990s to the present could be divided into four phases, and most firms are now in the outsourcing and expansion phase. Relying on the huge production networks, these two industries are likely to be improving their popularity and added value through global cooperation.

치열한 경영 환경을 돌파하기 위해 제품 생산 기지를 해외에 구축하는 글로벌화가 진행되고 있다. 생산 요소 중 기계나 장비는 쉽게 이전 가능하나, 고참 작업자가 소지하고 있는 경험적 지식은 이전하기 어렵다. 그러나 해외 생산 거점을 조기에 안정화 시키기 위해서는 경험자의 생산 지식이 필수적인 요소이다. 기존에는 이를 위해 국내 생산 전문가의 현지 공장 파견 및 현지의 국내 교육이 이루어졌다. 그러나 이는 한시적인 지원에 불과하며, 좀더 체계적이고 지속적인 지원, 즉 글로벌 지식 네트워크 구축이 요구 되어졌다.본 논문에서는 웹기반의 지식관리 시스템 구축 및 이를 활용한 해외 공장 지식 전이 활동에 대한 소개를 담고 있다. 즉 먼저 노하우 및 경험적 지식을 가지고 있는 국내 공장에 지식 고유 시스템을 구축하고 이를 활성화시켰다. 국내 경험적 지식은 사례 기반 추론을 활용하여 수집 및 활용되었다. 그리고 일정 수준의 지식이 시스템에 축적되었을 때 해외 생산 법인에 훈련 및 문제 해결 활용에 사용하도록 하였다.

MANET은 유선 기반망의 도움 없이 무선 노드들 간에 서로 협력하여 다중-홉으로 정보를 주고 받을 수 있도록 해주는 네트워크이다. 최근 MANET과 인터넷 망과의 통신이 요구되고 있고 이를 위해 무선 노드가 글로벌 IP 주소를 할당 받을 수 있어야 한다. 본 논문에서는 인터넷 게이트웨이를 통해 인터넷 망과 연결된 MANET 구조에서 무선 노드가 빠르게 글로벌 IP 주소를 설정할 수 있는 기법을 제안한다. 제안하는 기법의 성능 평가를 위해 NS-2로 실험을 수행했으며, 그 결과 기존 방법보다 빠르게 글로벌 IP 주소를 설정하고 네트워크 부하를 감소 시킬 수 있음을 입증하였다.

In this paper, we proposed a mechanism for effective cooperation in sensor network. There are a few mechanism like RBS, TPSN, FPSN for sensor network. However these are supporting synchronization among nodes without global state. Therefore, we proposed SGSM(Simple Global State Management) to maintain global state among sensor nodes. As experimental results, we confirmed loss rate is within 1% as maintaining global state with SGSM mechanism. In this paper, we defined global state in sensor network and introduced SGSM for improving timming accuracy in sensor environment.

This paper specifies a low-cost global mobility management architecture and protocol procedure called LC-$GM^2$, which is based on Proxy Mobile IPv6. In LC-$GM^2$, mobility management is performed by the network entity. The benefit is the elimination of the wireless link data delivery tunnel overhead between a mobile node and the access router. To compare with the well-known Hierarchical Mobile IPv6 mobility management protocol and GPMIP, the location update, packet delivery, and total cost functions generated by a mobile node during its average domain residence time are formulated for each protocol based on Fluid-flow mobility model. Then, the impacts of various system parameters on the cost functions are analyzed. The analytical results indicate that the proposed global mobility management protocol can guarantee lower total costs.

This study analyzed the structural changes in the global foreign direct investment (FDI) network using stock data from the International Monetary Fund's Coordinated Direct Investment Survey (CDIS) for 2009~2021. The results showed that the COVID-19 pandemic had a negative impact on the FDI links between countries and the activities of reciprocal relationships. The United States, the Netherlands, and the United Kingdom consistently play central roles in the global FDI network. The degree centrality of China has changed significantly over time in confronting the volatile situation of the world economy. Cross-tabulation analysis revealed a significant association between FDI clusters and geographic regions. Within each cluster, the linkage structure of FDI partners of closely connected individual countries has exhibited differential characteristics as the global economic environment changes.
