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.

본 연구에서는 중국 베이징시(북경시(北京市)) 중관촌(中關村) 클러스터를 사례로 첨단산업 네트워크의 공간적 특성을, 구매, 판매, 생산자 서비스, 정보, 연구개발에 초점을 두고 고찰하였다. 분석결과는 다음과 같다. 중관촌(中關村) 클러스터 기업의 구매, 생산자 서비스, 정보, 연구개발 네트워크의 공간적 특성은 클러스터 내부를 중심으로 하는 국지적 네트워크가 발달하고 지역적 뿌리내림이 강하게 나타났다. 이는 중관촌(中關村) 클러스터 기업은 중국을 대표하는 첨단 기업으로 원자재 및 부품은 클러스터 내 기업에 주로 의존할 수밖에 없는 산업환경적 특성과 정부의 정책적 지원 기관이 집중되어 있기 때문에 생산자 서비스 그리고 혁신에 관한 정보를 제공할 수 있는 제도적 기반이 상대적으로 잘 갖추어져 있기 때문이다. 또한 중관촌(中關村) 클러스터는 중국 내 타 지역에 비해 우수한 연구개발 역량을 가진 기업, 대학, 그리고 연구소가 집적되어 있을 뿐만 아니라 클러스터 내에 기술혁신을 위한 각종 지원기관이 집중되어 양적으로나 질적으로 최고수준의 연구개발 지원을 받고 있기 때문이다. 반면에 이 지역에서 생산된 첨단 제품들은 베이징뿐만 아니라 중국 전역 나아가서는 해외로 판매되고 있기 때문에 제품 판매 네트워크는 비국지적 네트워크가 강하다. 결론적으로 특정산업집적지가 혁신클러스터로 발전함에 있어서는 클러스터 주체간의 국지적 네트워크의 강화가 무엇보다 중요하다. 이런 점에서 중관촌(中關村) 클러스터는 네트워크 관점에서 본다면 기본적인 토대가 갖추어졌다고 할 수 있다. 그러나 국제적인 경쟁력을 강화하기 위해서는 국지적 네트워크뿐만 아니라 국제적 네트워크를 강화할 필요가 있다고 하겠다.

This data mining technique was used to extract useful information from percutaneous coronary intervention data obtained from the US public data homepage. The experiment was performed by extracting data on the area, frequency of operation, and the number of deaths. It led us to finding of meaningful correlations, patterns, and trends using various algorithms, pattern techniques, and statistical techniques. In this paper, information is obtained through efficient decision tree and cluster analysis in predicting the incidence of percutaneous coronary intervention and mortality. In the cluster analysis, EM algorithm was used to evaluate the suitability of the algorithm for each situation based on performance tests and verification of results. In the cluster analysis, the experimental data were classified using the EM algorithm, and we evaluated which models are more effective in comparing functions. Using data mining technique, it was identified which areas had effective treatment techniques and which areas were vulnerable, and we can predict the frequency and mortality of percutaneous coronary intervention for heart disease.

Ningbo Port develops quickly in recent years and with the combination of Ningbo Port and Zhoushan Port, it becomes another important port in the Shanghai International Shipping center. Competition between the two biggest ports in this area can't be avoided. The goal of this paper is investigating the competence of port from two angles, which are spatial structure of the ports cluster and neighboring ports' attraction to cargoes at conjunct hinterlands. The paper firstly uses the HHI index model and shift-share method to qualitatively and quantitatively analyze the data of container throughputs of ports in the shipping center, in order that investigates the spatial structure of ports cluster. Basing on above researches, the paper employs the location quotient to study Shanghai port and Ningbo port's hinterland distributions at Zhejiang province. The conclusion of this study:(I)the ports cluster of the Shanghai International Shipping Center is highly centralized, and undergoes a porcess of first centralization then decentralization since the mid of 90s, last century. (2)Hinterlands of Shanghai port includes: Hangzhou, Jiaxing, Huzhou and Quzhou districts; Hinterlands of Ningbo port includes: Ningbo, Taizhou and Zhoushan districts.

This study aims to subdivide consumers by attributes determined mainly by consumers of fresh ginseng. It is to compare and analyze the characteristics by cluster, and to deduce the implications on distribution and marketing. For this study, a survey was conducted targeting 250 consumers of fresh ginseng. The factors were deduced through performing the exploratory factor analysis on the results of the survey, and the consumers of fresh ginseng were classified through cluster analysis. As a result of the study, the attributes considered for the purchase of fresh ginseng were condensed to the three factors: physical characteristic factor, safety factor, and cultivation indication information factor. With these as the standard, the consumers of fresh ginseng were subdivided into the three clusters: safety-oriented consumption type, label-centered consumption type, and high involvement consumption type. It was found that there were differences in demographic characteristics and attributes considered for purchase of fresh ginseng by cluster analysis. This study suggests the implications for revitalization of the fresh ginseng industry by subdividing consumers of fresh ginseng and suggesting the characteristics by cluster.

The efficiency of the regional fiscal policy implementation is based on the achievement of target criteria in the formation and distribution of own financial resources of local budgets, reducing their deficit and reducing dependence on transfers. It is also relevant to compare the development of financial autonomy of regions in the course of decentralisation of fiscal relations. The study consists in the cluster analysis of the effectiveness of fiscal policy implementation in the context of 24 regions and the capital city of Kyiv (except for temporarily occupied territories) under conditions of fiscal decentralisation. Clustering of the regions of Ukraine by 18 indicators of fiscal policy implementation efficiency was carried out using Ward's minimum variance method and k-means clustering algorithm. As a result, the regions of Ukraine are grouped into 5 homogeneous clusters. For each cluster measures were developed to increase own revenues and minimize dependence on official transfers to increase the level of financial autonomy of the regions. It has been proved that clustering algorithms are an effective tool in assessing the effectiveness of fiscal policy implementation at the regional level and stimulating further expansion of financial decentralisation of regions.

The distributed system is playing a vital role in storing and processing big data and data generation is speedily increasing from various sources every second. Hadoop has a scalable, and efficient distributed system supporting commodity hardware by combining different networks in the topographical locality. Node support in the Hadoop cluster is rapidly increasing in different versions which are facing difficulty to manage clusters. Hadoop does not provide Node management, adding and deletion node futures. Node identification in a cluster completely depends on DHCP servers which managing IP addresses, hostname based on the physical address (MAC) address of each Node. There is a scope to the hacker to theft the data using IP or Hostname and creating a disturbance in a distributed system by adding a malicious node, assigning duplicate IP. This paper proposing novel node management for the distributed system using DNA hiding and generating a unique key using a unique physical address (MAC) of each node and hostname. The proposed mechanism is providing better node management for the Hadoop cluster providing adding and deletion node mechanism by using limited computations and providing better node security from hackers. The main target of this paper is to propose an algorithm to implement Node information hiding in DNA sequences to increase and provide security to the node from hackers.
