Study on Development of Appraisal Business Performance Indicator

Today, the paradigm of the contents industry is fast changing like in, for example, convergence of contents, cloud computing environment, and diffusion of smart device supply. As a result, copyright competition is intensified day by day between the contents industries as well as between countries with the advent of “global cultural competition era”. As a result, copyright disputes are occurring and appraisal business to make judgments on such matters is increasing. In this study, we intended to look into the concept of performance indicator and the method to approach it in order to develop a balanced score card based performance indicator as a criterion to measure whether organizational missions, strategic goals or performance goals of appraisal business have been accomplished or not, and to develop performance indicator of appraisal business for public organizations performing appraisal businesses using the balanced score card based method.

The study on content based multimedia data retrieval system

Of late, advance in hardware and communications technology has been rapidly increasing the demand for diverse multimedia information, which, including all image, audio, video, text, numerical data, etc., should be designed to excel the existing information processing system in the functions of data storage, search, transmission, display, etc. The newest image retrieval system is gradually being converted from text-based into content-based retrieval, which uses the image content itself as features. In content-based retrieval, how to combine the color, shape, layout, texture, etc. used for describing each image or object is considered an important element. The existing method has chiefly used histogram out of the content-based image method using color information, but this has a drawback in being sensitive to brightness of light and the object size in the image. Thus, the present methods is intended to design and implement a system that can retrieve images similar to the query image from image database without losing image information in the use of color features.

The Study for the User Oriented Service Design for Inter-organizational Collaboration

Recently, a diversity of achievement has been attained such as diffusion of e-Business and construction of infrastructure to standardize B2B for each industry through B2B projects. Considerable results are currently obtained from building up electronic guarantee platforms based on this infrastructure, at the same time, a demand is increasing for information on e-Marketplace with electronic guarantee platforms, or selling and purchasing companies. However, information on major or newly expected transacting companies is not properly delivered, and there are practical difficulties for each company to prepare infrastructure solving them, therefore, a need is emerging to eliminate risk factors with e-Commerce by providing reliable business information. This study would like to establish a foundation for non-financial collaborative information systems preparing a win-win cooperative system between large and small companies and a sustainable management system, and to provide chances for credit reference agencies to create business opportunities as a new optional service.

A Case Study on Cooperative Real-time Quality Monitoring Service Utilizing Sensor Networks

Introduced an ERP system for increasing their profitability and a point of production system, shop floor controller system etc. for managing sites, however, data has still been managed manually in production sites, and the difficulty lies in the real-time process control due to limitations of the introduced information system. Therefore, this paper studied examples of cooperative real-time quality monitoring services utilizing sensor networks that could manage the real-time production process by integrating various technologies of ubiquitous sensor networks together with RFIDs considering characteristics for each workplace as well as for each industry.

A Study on Design of FMT Framework for Flex Quality Assurance

The paradigm of RIA (Rich Internet Application) emerged since users¡® tendency to use web applications was changed for the sake of convenience, and the Flex was presented as a platform to develop the RIA with the advangtage of prevalance by the Adobe. The Flex is mainly composed of configuring user screens, which has insufficient compatibility and maintenance due to its unified layer. Accordingly, this paper woudl design and implement a FMT (Flex Mlti-Tier) framework to improve compatibility and maintenance of the Flex.
