As the Internet is more embedded in people's lives, Internet users draw on new Internet applications to express themselves through "user-created content (UCC)." In addition, there is a noticeable shift from text-centered contents mainly posted on bulletin boards to multimedia contents such as images and videos on UCC web sites. The changes require different way of recommendations comparing to traditional products or contents recommendation on the Internet. This paper aims to design UCC recommendation methods with user behavior data and contents metadata such as tags and titles, and compare performances of the suggested methods. Real web logs data of a major Korean video UCC site was used to empirical experiments. The results of the experiments show that collaborative filtering technique based on similarity of UCC customers' preferences performs better than other content-based recommendation methods based on tag information and content metadata.

Despite steady economic growth of e-learning industry, manpower is lacking in e-learning industry. In this study, We developed a new e-learning business model including open market portal system to solve this problem. The existing e-learning business models required complicated procedure for creating contents. Therefore it took long time and great expense. But in this study we developed the business model with open market portal system, it can support to make easily for e-learning contents. We analysed usefulness our program and other popular programs with thirty lecturers. As a result of survey, usefulness of our system is presented. The study suggests differently the student-centered business model and the lecturer-centered business model than existing e-learning business model had the manufacturing company-centered business model and the services-centered business model. We anticipate the new business model invigorate the e-learning industry.

Recently, it has increased projects in the Oil and Gas industry as growing plant of overseas construction market. Therefore, domestic companies need to set some aggressive plans up that secure competitiveness of international plant business such as enhancing productivity, technological ability and statistical management. Specifically in the Oil and Gas industry of overseas plant business requires implying information in EPC (Engineering, Procurement and Construction, below EPC) more, but it has not been suggested an appropriate breakdown system for contents that manages the information each EPC phase, which lead to problems such as revision of design document, occurring duplicated work and omissions of each participant. For these problems, we find market share decreasing and competitiveness running down. Thus, for increasing practical use of contents management system and construction industry's information, this paper suggests a contents breakdown system based on BPM (Business Process Management), defines business process and systematizing knowledge needed, and finally analyzing contents information that establish information among industrial facilities in Design phase which is the weakest part of domestic companies.

This study presents a contents model designed for business records that require long-term preservation. The contents model is based on the PREMIS(Preservation Metadata: Implementation Strategies) data model and the ISAD(G)(General International Standard Archival Description). The study selected the record collection of "the records of the overseas petroleum business and oil field development of A company located in B country." This collection requires permanent preservations by the nation and even beyond. It was attempted to establish the concepts of intellectual objects in the PREMIS data model to apply the PREMIS data model to the business records specifically. In other words, the study established the principles for differentiation of the classes in the record contents and the hierarchy structure, and the hierarchy model was developed for business records contents to derive the business records model based on those principles.

In this paper, we argue that characteristics of ubiquitous business are different from those of e-business or m-business. We have developed a u-business model development framework incorporating the concept of value co-creation experiences, which is a core of the ubiquitous business paradigm. The framework of u-business model development presented in this paper consists of eight steps such as defining of domain, discovery of opportunity nucleus, defining of potential co-creation experience environment, deriving candidates of u-business services, selecting u-business killer services, defining value propositions of u-business killer services, defining u-business killer service offerings, and drawing a resource map of u-business killer services. The proposed u-business model development framework offers useful guidelines for practitioners to develop successful u-business models under a ubiquitous business paradigm.

As a result of FGI of experts who works in cultual contents industry, two axes of 'Industry attractiveness' and 'Technology strength' were deduced as main measurement factors and twenty-nine detail factors were deduced. After that those detail factors were deduced through two-time survey aimed cultural contents industry experts. To find out importance of each factor, AHP method was used. This study suggests the model that measure present level of cultural contents industry. Furthermore, we figured out feature each faces of matrix to suggest business strategy guide for future sustained growth.

As mobile market grows more and more fast, the mobile contents market, especially music contents for mobile phones have recorded remarkable growth. In spite of this rapid growth, mobile web users experience high levels of frustration to search the desired music. New musics are very profitable to the content providers, but the existing collaborative filtering (CF) system can't recommend them. To solve these problems, we propose an extended CF system to reflect the user's real preference by representing the characteristics of users and musics in the feature space. We represent the musics using the music contents based acoustic features in multi-dimensional feature space, and then select a neighborhood with the distance based function. Furthermore, this paper suggests a recommendation for procedure for new music by matching new music with other users' preference. The suggested procedure is explained step by step with an illustration example.

The wisdom contents consists of an ordinary person's ideas and experience. The Wisdom Market [1] is an online business model where wisdom contents are traded. Thus, the general public could do business activities in the Wisdom Market at ease. As the wisdom contents are themselves the thought of persons, there exists many similar or duplicated contents. Existing copyright protection schemes mainly focus on the primary author's right. Thus, it's not appropriate for protecting the contents of Collective Intelligence that requires to protect the rights of collaborators. There should exist a new method to be dynamic capable of combining and deleting rights of select collaborators. In this study, we propose collective copyright authentication scheme suitable for the contents of Collective Intelligence. The proposed scheme consists of collective copyright registration, addition and verification protocols. It could be applied to various business models that require to combine multiple rights of similar contents or to represent multiple authorships on the same contents.
