This paper deals with the methods for selecting the key research areas, which fit for the large, multi-disciplinary, and long-term programs by making use of Technology Cluster Analysis. This method is applied to mano-technology field at the level of national R&D program. 56 nano-technologies are analyzed and grouped into three main clusters based on the survey data from 180 experts. Three main clusters are \circled1 naro-materials related cluster, \circled2 naro-device related cluster, and \circled3 naro-bio related cluster. These three clusters are coincided with the focused areas of nano-technology in Korea. Each cluster is analyzed in view of its competence position.

It is generally known that a Science and Technology Park - as a representative example of an Innovation Cluster - produces network synergy among industry, university, research institutes, and other innovation actors in a specific area, so that it has a competitive edge over other regions in technological innovation. However, as the novel Coronavirus (COVID-19) pandemic unfolds, it has become necessary to reduce face-to-face contacts and this could lead to lesser network synergy being produced in an Innovation Cluster. With this background, this research was designed and conducted to evaluate how COVID-19 has changed the activities in Innovation Clusters and explore future development scenarios. In order to find out the changes occurring in an Innovation Cluster, a survey was conducted among the people in Science and Technology Parks. The survey result shows that people are experiencing difficulties in technological innovation and support activities, and face-to-face contacts have been reduced in the Innovation Cluster. A scenario planning sought to explore the future development of the Innovation Cluster. It suggests that the transformation into a Digital Innovation Cluster, which is less affected by physical distance, but can still maintain the effectiveness of the networks, can be the key strategy for the future Innovation Cluster.

This paper reviews regional innovation policy in Japan. 'Technopolis' policy, the first technology-based regional development policy in the world, was implemented in Japan. Nonetheless, technology-based regional endogenous development did not occur. Then, regional technology transfer was pursued. In order to make use of universities and public research institutes in a region for development, university-industry collaboration and cross-over, such as university spin-offs, were promoted. Within this background, new technology-based regional development policies have been introduced based on a cluster approach. These policies are the knowledge cluster Initiative and the industrial cluster program. However, existing companies have difficulty in carrying out innovation. This paper argues that a cluster to create new start-ups that carry out innovation is also needed and explains a new concept of venturing cluster. Based on this new cluster concept, this paper analyzes the situation of Sapporo in Japan, where many university spin-offs are being created in the biotechnology field.

The aim of this study is to examine of the cluster approach to ensure high rates of innovation, information and communication enterprises of information technology cluster in order to enhance the competitiveness of regions. Keeping with the previous literature, the present research determined that the novelty of the problem, concerning of the creation IT clusters as drivers of new generation, i.e. a kind of platform of "startup accelerators" through the creation of previously not existing in the country high-tech industries and sectors of the economy. The study employs system approach involves to determine prospective directions of the formation of clusters of IT industry, also applies structured approach to shows relationships between elements of cluster systems (participants of cluster), as well as focusing on some aspects of cluster development such as networking. Based on this analysis we have proposed to create clusters in regions, which can play the role of translator's innovations at the periphery of the country. This research shows that formation of IT clusters is one of the most successful tools to avoid of dependence of Kazakhstan from raw materials.

In year 2003, the Daedeok Science Town(DST) has celebrated its 30 years of anniversary and achievement in science and technology development. However, there is a criticism that DST has not played its expected role in Korea's National Innovation System. Recognizing this criticism, the development of DST was evaluated in the perspective of innovation cluster. The research shows that DST has been following the downstream path of evolution - from S＆T development to business development - and is in the early stage of R＆D-driven Innovation Cluster. Not only the development factors of DST innovation cluster were identified but the DST was compared with other internationally recognized innovation clusters. Finally, it is suggested that the business related functions should receive due attention in innovation cluster policy.

새 정부의 국정방향인 창조경제는 '창의적 상상력과 과학기술, ICT가 결합하여 활발하게 창업 또는 기존 산업과 융합하고 이를 통해 새로운 시장, 산업 및 일자리가 창출되는 성장전략'이라고 정의할 수 있다. 이러한 맥락에서 혁신 클러스터는 그 정책 목표가 유기적 생태계 관점에서 기술혁신을 촉진하는 것이므로 창조경제 실현의 유효한 정책 수단으로 활용될 수 있다. 이러한 개념적 배경을 기반으로 본 연구에서는 창조경제형 ICT 융합 혁신 클러스터 정책 시사점을 얻기 위해 최근 주목받고 있는 판교테크노밸리 조성 사례를 분석하였다. 먼저 조성 측면에서는 환경 변화에 대한 지방정부의 유연한 대응, 철저한 사전 기획, 민간과 공공의 균형적 참여가 중요한 요인인 것으로 나타났다. 창조경제 활성화 측면에서는 우수인력 집적을 위한 정주여건 확보, 융합을 촉진할 다양한 혁신주체들의 집적과 이들 간의 네트워크 활성화, 창업 촉진을 위한 지원 프로그램 등 창업환경 조성이 중요한 요인으로 분석되었다.

Linux cluster Server makes a high performance PC cluster system, and provides scalablity and availability as compared with an expensive single server. In this paper, we design and implement a VOD streaming service system to serve video and audio streaming services on the Linux cluster server. Our Streaming server supports the MS Window Media Format based on the RTSP streaming protocol.

WSN 분야의 대표적인 알고리즘의 하나인 LEACH는 시스템 수명동안 모든 노드들이 균일한 횟수로 클러스터 헤더가 되는 것을 보장한다. 하지만 각 라운드별로 일정한 클러스터 헤더 수를 보장하지 못하여 클러스터 헤더가 선출되지 못하는 경우가 발생하거나 적은 수로 선출되는 경우가 발생한다. 클러스터 헤더가 적게 선출될 경우 클러스터 헤더에 높은 부하가 걸린다. 또한 선출된 클러스터 헤더의 위치에 따라 센서 노드가 소속되지 않은 클러스터가 발생할 경우도 있다. 이에 본 논문에서는 관심 영역을 일정한 섹터로 나누어 각 섹터마다 클러스터 헤더를 무작위로 하나씩 선출하는 알고리즘을 제안한다. 클러스터 구성 시 각 센서 노드는 가장 가까운 클러스터 헤더에 소속되어 클러스터 구성은 섹터와는 무관하게 진행된다. 이 알고리즘은 매 라운드마다 일정한 수의 클러스터 헤더를 보장하며 소속된 센서 노드가 없는 헤더가 발생하지 않도록 한다.

The advent of Wireless Sensor Networks (WSN) has led to their use in numerous applications. Sensors are autonomous in nature and are constrained by limited resources. Designing an autonomous topology with criteria for economic and energy conservation is considered a major goal in WSN. The proposed honey-hive clustering consumes minimum energy and resources with minimal transmission delay compared to the existing approaches. The honey-hive approach consists of two phases. The first phase is an Intra-Cluster Min-Max Discrepancy (ICMMD) analysis, which is based on the local honey-hive data gathering technique and the second phase is Inter-Cluster Frequency Matching (ICFM), which is based on the global optimal data aggregation. The proposed data aggregation mechanism increases the optimal connectivity range of the sensor node to a considerable degree for inter-cluster and intra-cluster coverage with an improved optimal energy conservation.
