Due to the popularity of IT technology and smart devices, SNS (Social Networking Service), there are increasing users using. This causes increasing of data generated by the SNS may also, IT companies are developing a technique to create value in this data. In this paper, we design and implement the system that statistical information for connecting to the tweeter to create value of the data generated by the tweeter. The proposed system is a system using Mahout behind collected data and stored as a tweeter NoSQL based statistics that the contact information of the user. The developed system is expected to be helpful in providing the background technology necessary to create value in the data of the tweeter.

This study alms to perform Business Process Reengineering and to develop tourism statistics information system through the development of tourism statistics process design supporting tool. With this tool, we can manage tourism statistics systematic and integrated. Also it offers a tourism decision making supporting tool. Tourism statistics process design supporting tool consists of information provider, information maker, and information user. This tool can improve bossiness process, and rationalize system architecture. 49 business processes were designed and a database which connected with outside system was designed by this supporting tool. By these means, this tool provide more reasonable and effective decision making tool, when it comes to plan tourism development.

이 논문에서는 보다 효율적인 단조 재공 관리를 위한 새로운 시스템을 제안한다. 지금까지 효율적인 재공 또는 재고 관리 통해 생산성을 향상시키기 위한 다양한 연구가 진행되어 왔다. 특히 바코드, RFID 기술, 영상 인식 기술 등 다양한 IT 기술을 접목을 시도해 왔다. 그러나 단조 재공관리 시스템의 특성상 이러한 접근 방법을 적용하는데 많은 문제점을 야기한다. 열악한 환경으로 인환 높은 훼손 가능성, 특정 단말기에 대한 종속성과 높은 관리 비용, 부정확한 적재 위치 관리 및 최적의 적재 위치 파악이 어렵다는 문제점을 지닌다. 따라서 이 논문에서는 기존 접근 방법의 한계를 극복하고 단조 재공 관리 환경에 적합한 새로운 시스템을 제안한다. 제안 시스템은 스마트폰과 GIS 시스템을 이용하며 앞서 언급한 많은 문제점을 해결 및 보완할 수 있다는 장점을 지닌다.

Recently, some reliability problems are notified on the information security industry survey due to the differences of survey purpose, criteria and methodology among the pursuing organizations. This paper firstly identifies the issues of survey methodologies which are currently applied in the information security industry, and then proposes a business outlook survey system which can be adapted in various domain, even in effectively. The proposed system may be applied in surveys of the business outlook, supply and demand, and difficulty factor, with a co-operative database, Especially, it would be utilized as a great tool when the survey is conducted in repeatedly.

오늘날 기업은 IT 서비스 제공자에게 급변하는 비즈니스에 신속하게 대응하고 안정적 IT 서비스 지원을 통한 비즈니스 서비스의 연속성 증대와 IT 조직의 효율적 운영을 통한 운영 비용 절감을 요구하고 있다. 이에 국내외 ITO(IT Outsourcing) 기업들은 고객에게 TCO(Total Cost of Ownership : 총소유비용) 경감 외에 Time-to-Market 단축과 고품질의 IT 서비스를 제공하기 위한 전략적 지원체계가 필요하게 되었고 SLA를 기반으로 한 SLM 프로세스의 체제 정비에 심혈을 기울이기 시작했다. 그러나 이제까지의 SLM 프로세스는 단순 정보만 제공되어 IT 서비스를 유지, 개선시키기에는 한계가 있다. 그러므로 여러 프로세스들이 통합되고, 측정지표에 대해 실시간으로 자동 집계되어 통계 리포트를 제공하고 통계결과를 자동으로 보고하여 문제 발생시 원인 파악 및 대처가 빠르게 진행될 수 있도록 자동화된 통합 SLM 시스템 구축이 필요하다. 본 연구에서는 통합되고 자동화된 SLM 프로세스 모델 제시를 통해 프로세스 단계별로 성공요인을 도출하고 다양한 기업에 적용 후, 실증적 기대효과를 제시하여 향후 SLM 시스템을 구축하는 기업에게 실질적인 지침을 마련해주고자 한다.

As the amount of web contents in the Internet increases, it becomes hard to find out statistics that users want. In this paper we propose an analysis system based on the statistics of words, which can be used to prospect trends in a specific area. We applied this system to job recruiting site and we can find out trend and statistics about what part of technology is needed in job market and the result of this paper can be used for an application such as restructuring curriculum of a department in universities. It can also be used to predict trend in other areas.

There is a close relationship between indicators of statistics and performance measurement in international standards, working sections and the data items similarity in academic libraries. However, this co-relationship between statistics and measuring performance in the Korean academic library is not related to each other in terms of designing or usage. In order to prove this, the co-relationship between indicators of statistics and performance measurement has been researched based on applications of international standards and data. The international result shows 45% of overlapping in statistical and measuring performance indicators. However, there is only 14 to 26% of the co-relationship in existing statistics and performance measurement in Korea. A considerable improvement of the co-relationship between the indicators has newly been found. Therefore, in developing online system of academic library statistics, it is essential to provideinclusive information between indications of statistics and performance measurements.

Recently many researches on data analysis using spatial statistics have been studied in various field and the studies on small area estimations using spatial statistics are in actively progress. In analysis of lattice data, defining the neighborhood information system is the most crucial procedure because it also determines the result of the analysis. However the used neighborhood informal ion system is generally defined by sharing the common border lines of small areas. In this paper the other neighborhood information systems are introduced and those systems are compared with Moran's I statistic and for the comparisons, Economic Active Population Survey (2001) is used.

This paper introduces CybeRClass(Cyber Regression Class). CybeRClass uses the technique of animation arid voice to teach regression analysis. The structure of this system make it possible to extend to multivariate analysis methods such as discriminant analysis and cluster analysis. Tools for multimedia is Multimedia ToolBook, and Xlisp-Stat is used for statistical computation and statistical graphics.
