This paper suggests policy implications for Daedeok Innopolis (DI) in Daejeon by comparing the development and problems of DI with the San Diego biotechnology cluster. DI has strengthened its capabilities for technology commercialization and business activities after having created and managed by the Korean central government. While DI has been successful in increasing the number of institutes, researchers, research activities, however, its dynamism is not rigorous enough to be a regional innovative system. San Diego's scientific and entrepreneurial community shows the importance of formulating social and spatial contexts for mutual interactions and engagements. In San Diego, UCSD and networking organizations, especially CONNECT, are central in promoting interactions and communications between regional constituents including entrepreneurs, academics and local governments. The mechanisms of San Diego biotechnology imply that DI should provide more attention to designing and developing social and geographical space that can unleash the creative power of social interactions. To build an innovative regional system, DI needs to renovate its space, public-private relationship and networking platforms.

This study attempts to explain the mechanism behind the migration from vertically integrated value chain architecture to an innovation ecosystem consisting of horizontally separated layers in value chain. We first present a comprehensive framework based on the theoretical analysis of the drivers for migration to an innovation ecosystem, which are standard (institution), capability distribution, and transaction costs. The theoretical framework suggests that the migration to an innovation ecosystem is explained by the influence of standard on the evolutionary change of capability distribution and transaction costs. In particular, when the new de-jure standard competes with the de-facto standard, the new de-jure standard has the greatest impact on the distribution capabilities and the transaction costs. Based on this theoretical framework, we analyze the latest SDN (Software Defined Networking) case of the network industry. SDN standard has transformed the industry from a vertically integrated value chain architecture to a horizontally separated one with its influence on the distribution capabilities and the transaction costs in the industry.

Mobile Edge Computing (MEC) and Information-Centric Networking (ICN) are essential network architectures for the future Internet. The advantages of MEC and ICN such as computation and storage capabilities at the edge of the network, in-network caching and named-data communication paradigm can greatly improve the quality of video streaming applications. However, the packet loss in wireless network environments still affects the video streaming performance and the existing loss recovery approaches in ICN does not exploit the capabilities of MEC. This paper proposes a Deep Learning based Loss Recovery Mechanism (DL-LRM) for video streaming over MEC based ICN. Different with existing approaches, the Forward Error Correction (FEC) packets are generated at the edge of the network, which dramatically reduces the workload of core network and backhaul. By monitoring network states, our proposed DL-LRM controls the FEC request rate by deep reinforcement learning algorithm. Considering the characteristics of video streaming and MEC, in this paper we develop content caching detection and fast retransmission algorithm to effectively utilize resources of MEC. Experimental results demonstrate that the DL-LRM is able to adaptively adjust and control the FEC request rate and achieve better video quality than the existing approaches.

In the upcoming post-app era, real-time, intelligent and immersive services such as autonomous vehicles, virtual secretaries, virtual reality, and augmented reality are expected to dominate. However, there is a growing demand for new networking and computing infrastructure capabilities because existing physical connection-oriented networks and centralized cloud-based service environments have inherent limitations to effectively accommodate these services. To this end, research on intelligent edge network computing technology is underway to analyze the contextual situation of human and things and to configure the service environment on the network edge so that the application services can be performed optimally. In this article, we describe the technology issues for edge network intelligence and introduce related research trends.

Information-centric networks operate under the assumption that all network components have built-in caching capabilities. Integrating the caching strategies of information centric networking (ICN) with wireless virtualization improves the gain of virtual infrastructure content caching. In this paper, we propose a framework for software-defined information centric virtualized wireless device-to-device (D2D) networks. Enabling D2D communications in virtualized ICN increases the spectral efficiency due to reuse and proximity gains while the software-defined network (SDN) as a platform also simplifies the computational overhead. In this framework, we propose a joint virtual resource and cache allocation solution for latency-sensitive applications in the next-generation cellular networks. As the formulated problem is NP-hard, we design low-complexity heuristic algorithms which are intuitive and efficient. In our proposed framework, different services can share a pool of infrastructure items. We evaluate our proposed framework and algorithm through extensive simulations. The results demonstrate significant improvements in terms of visiting latency, end user QoE, InP resource utilization and MVNO utility gain.

Purpose - There have been many studies regarding the preceding factors required for success of start-up. The purpose of this study is to verify one of the paths by which the individual characteristics of founders and governmental support lead to enhanced start-up performance, via entrepreneurship and network building. Research design, data, methodology - Data for this study was collected from surveys of 332 founders throughout South Korea, and statistical analyses of this data were performed using SPSS 22.0 and Smart PLS 2.0. To verify our hypothesis, path analysis was performed using a structural equation model. Results -The variables, entrepreneurial self-esteem and experience were found to have positive effects on the entrepreneurship and networks. Secondly, governmental support did not have significant positive effect on entrepreneurship, but it did have positive effect on networking. Thirdly, entrepreneurship and networking were confirmed to have positive effects on both the utilization of opportunities and financial performance, which are variables indicating start-up performance. Conclusion - Although founder's characteristics are important for success of start-up, it is also critically important to actively utilize governmental support. Notably, many founders suffer from inadequate networks. They would be able to enhance their start-up performance by utilizing various governmental support programs to reinforce their network capabilities.

본 연구는 기술혁신 역량을 강화하기 위한 중요한 프레임워크로 논의되고 있는 개방형 혁신에 초점을 맞춰 개방형 혁신활동을 내향형 혁신활동과 외향형 혁신활동을 구분하고, 영향요인을 환경특성, 기업특성, 재도특성으로 분류하여 국내 149개 제조기업의 설문응답 내용을 토대로 실증분석을 실시하였다. 그 결과, 환경특성 요인의 경우 시장경쟁정도와 기술변화정도가 내향형 혁신활동에 영향을 미치는 것으로 나타났다. 이는 기업들이 시장경쟁정도가 심해지거나 기술변화정도가 높아질 경우, 자사의 기술 개발 촉진 및 시장에서의 우위를 유지하거나 선점하기 위하여 공동연구, 사용자 혁신 등 외부로부터의 기술도입 및 외부의 정보활용에 노력을 기울인다는 의미로 해석될 수 있다. 기업특성 요인의 경우, 내향형 혁신활동은 연구개발인력, 연구개발투자, 국제화사업건수, 해외수출, 조직문화 개방성에 의해 영향을 받는 것으로 나타났으며, 외향형 혁신활동은 국제화조직특성, 기업가정신(역량특성)에 영향을 받는 것으로 나타났다. 이는 기업들이 내향형 혁신활동을 강화하기 위해서는 우선적으로 연구인력, 연구비 등의 R&D 투입요소의 증대에 관심을 갖아야 됨을 의미하며, 반면 외향형 혁신활동을 높이기 위해서는 국제화 전담조직을 육성하며, CEO도 독자적인 내부 기술혁신활동에 기업가정신을 발휘하기 보다는 개방적이고 협력적인 기술혁신활동에 기업가정신을 집중해야 됨을 의미한다. 제도특성 요인의 경우 내향형 혁신활동에서는 기술네트워킹에 의해, 외향형 혁신활동의 경우 산업클러스터 입주여부 및 기술네트 워킹에 의해 영향을 받는 것으로 나타났다. 이는 정부에서 제도적으로 개방형 혁신활동을 촉진시키기 위해서는 산업클러스터 조성과 기업들의 기술네트워킹 확대에 노력을 기울여야 함을 의미한다.
