Recently Usage statistics are widely available from online content providers. However. the statistics are not yet available in a consistent data container and the administrative cost of individual provider-by-provider downloads is high. The Standardized Usage Statistics Harvesting Initiative (SUSHI) is developing an automated request and response protocol for moving Project COUNTER (Counting Online Usage of Networked Electronic Resources) Code of Practice usage statistics from providers to library electronic repositories. SUSHI will help libraries make better decisions by reducing the administrative overhead of using Project COUNTER statistics. Publishers in the recording and exchange of usage statistics for electronic resources, initially journals and databases. By following COUNTER's Code of Practice, vendors can provide library customers with Excel or CSV (comma delimited) files of usage data using COUNTER's standardized formats and data elements. The result is a consistent, credible, and compatible set of usage data from multiple content providers. On this study, We propose the acquisition model of usage data based on SUSHI for KESLI that is overseas electronic journal consortium in korea.

With the increasing importance of BPO for sustainable growth of small venture business, BPO theories have been developed over the past several decades. This study was designed to examine the contextual factors affecting the managerial attitudes towards the BPO of small venture business, as well as the intentions to increase its level. The findings suggest that cost saving was not the primary ingredient positively affecting the attitude towards BPO. However, both specialized resources and quality improvement had a positive relationship with the attitude towards BPO. Finally, this study identified that a positive attitude towards BPO positively affects the intention to increase the level of BPO. This study implies that the survival and success of small venture firms necessitates that they utilize BPO effectively and efficiently in today's highly globalized and severely competitive environments.

With the increasing need for big data processing, building a shared big data processing platform is important to minimize time and monetary costs. In shared big data processing, multitenancy is a major requirement that needs to be addressed, in order to provide a single isolated personal big data platform for each user, but to share the underlying hardware is shared among users to increase hardware utilization. In this paper, we explore two well-known shared big data processing platform models. One is to use a native Hadoop cluster, and the other is to build a virtual Hadoop cluster for each user. For each model we verified whether it is sufficient to support multi-tenancy. We also present a method to complement unsupported multi-tenancy features in a native Hadoop cluster model. Lastly we built prototype platforms and compared the performance of both models.

The first aim of mass product of glass in Automatic bottle glass industry is to decrease the cost and to increase the quality. Second, the cullet is how widely used to save the energy and reducing of ecomaterials. However the physical and chemical properties of Soda-lime glass would be come true at the lower than 2% $Al_2 O_3$. Unfortunately the $Al_2 O_3$ contents of domestic silica is greater than 4% Since small glass class than 200ml bottle is made in domestic silica the producting efficiency would be decreased due to the defect such as cord, knot, devitrite, pore etc. There are many problems such as devitrifiacation and deteriorated effect on production in glass industry became of increasing of plate glass cullet. It is tried to solve these kinds of problems using various analysing methods in this experiments.

The critical strength of outsourcing system is to enhance the competitive power of the company by applying the centralization of management resources. This strategy has been used in library management and become the general method. The libraries in the U.S. stated to adopt the outsourcing system to organize the information of library works. Those in Korea also commence to use this method later on. The main reason of outsourcing the cataloging and classification works in the library was to reduce the budget; however, result were diverse. The efficiency on performing works was positive while the quality of bibliographic record was not guaranteed. Regardless of various opinions, The National Library of Korea decided to apply the method to cataloging and classification considered as a major work in maintaining library. This study is to analyze and criticize the decision made by The National Library of Korea.

After the IMF bailout, the Environment of Domestic Construction Industry had changed dramatically Therefore the IMF, Domestic Construction Firms are secured by the government regulations and some traditional Practices. However, due to the following reasons: a decrease in public works, an increase in uncertainty of market prediction, the change of bid system, and increase in construction firms, recently the competition among construction firms has became keen. Under the serious competition, In order that medium-size construction firms survive in the construction market, it is need to establish the strategy that could increase productivity. In order to establish the strategy, firstly, construction firms should set up an appraisal standard of construction firms. This paper propose a suitable appraisal standard that construction firm's strategy establish in environment change of the construction industry.

Recently, the interest in optical network with multifiber link is continuing to rise since the network traffic has been growing exponentially. However, growing traffic in network leads to increasing the energy consumption of the network equipment. In this paper, we propose a dynamic routing and wavelength assignment (RWA) algorithm based on V-like cost function and layered graph to improve energy efficiency in IP over WDM network with multifiber link. The V-like cost function is used to decide the fiber cost according to the number of used wavelengths. The layered graph with multifiber link is used to select the energy efficient route and wavelength. The proposed RWA algorithm is compared and analyzed with conventional algorithm in view of average power consumption and blocking probability through OPNET modeler.

Under the paradigm of sustainable green growth at the national level, various researches and applications for energy saving in the construction field has been attempted. As a part of energy saving efforts, lightweight concrete was investigated for thermal insulation concrete with phase change material (PCM) which has high heat storage capacity. As a part of energy saving efforts, thermal insulation concrete was investigated and evaluated with lightweight aggregate impregnated by PCM which has high heat storage capacity. As a result, it is found that concrete with lightweight aggregate impregnated by PCM is effective to prevent its quality deterioration by reducing water absorption rate of lightweight aggregate. In addition, it has shown that concretes using lightweight aggregate and impregnated lightweight aggregate improve heat insulation property 33% and 40~43% compared with using normal aggregate, respectively. It is that the lightweight aggregate concrete with impregnated lightweight aggregate has 12~14% lower thermal conductivity than unimpregnated.
