Digitalized multimedia contents is changing active digital contents in form passed from manufacturer directly to consumer though digital network of high speed, also face with big problem that is protection of rights to protect digital contents, to protect those and effort to active digital contents process height. Also, in situation that require change to more efficient system, the efficiency of rights document that is basic intermediate to be used in business of digital contents field is emphasized. Therefore, the design of common business model to share contents that have same purpose without depending on specific system to offer contents with another system is required. This paper designed adaptable rights business model to general digital contents, and designed and implemented rights document editing system to editable document for Right management according to designed business model.

This study analyzed the diffusion process of digital convergence products focused on camera phon to compare the traditional adoption-diffusion model with use-diffusion model proposed by Shih and Venkatesh(2004). The results suggested that observability, perceived usefulness, innovativeness, relative advantage have effects on the intention of repurchase in the adoption-diffusion model. On the other hand, the intention of repurchase has been affected by technological sophistication, satisfaction, innovativeness, relative advantage in the use-diffusion model. These results imply that the traditional adoption-diffusion model could be applied to the cases of the digital convergence products. In addition, the results also show that the use-diffusion model is superior to the traditional model in analyzing the diffusion of digital convergence products.

This paper discusses revenue model of digital TV broadcast service(D-TV) and presents the basic framework for integrated strategy of applications. Also this paper presents the cases of D-TV in the frame of integrated model. The broadcasting operators should focus on interactive advertising and revenue generation utilizing customer participation. Also, they should utilize the strengths as a platform operator. The contents provider should be concerned about the retail revenue rather than commission revenue. The middle ware provider should develop new interactive D-TV service rather than system use fee or consulting fee.

In the rapidly developing information technology environment, information management organizations need to effectively evaluate their digital maturity and clarify the direction of improvement to effectively respond to rapidly changing environments. This study derived weights for the digital curation maturity model developed by KISTI from the perspective of digital transformation to facilitate effective evaluation and direction setting of information management organizations. Relative importance was derived as a weight in the major and middle categories of the model through the AHP technique. Summarizing the results, when the major categories of the entire model are measured on the basis of 100 points, technology is 27 points, data is 24 points, strategy is 19 points, organization (manpower) is 16 points, and (social) influence is calculated as 14 points. In addition, weights for each subcategory were presented for each major classification based on a perfect score of 100 points. It is expected that a more objective and reasonable evaluation will be possible by applying the weights for each area derived from this study to the digital transformation maturity evaluation model.

The 4th Industrial Revolution is making a big change for our company like the tsunami. The CPS system, which is represented by the digital age, is based on the data accumulated in the physical domain and is making business that was not imagined in the past through digital technology. As a result, the business model of the 4th Industrial Revolution era is different from the previous one. In this study, we analyze the trends and the issues of business innovation theory research. Then, the business innovation model of the digital age was compared with the previous period. Based on this, we have searched for a business model suitable for the 4th Industrial Revolution era. The existing business models have many difficulties to explain the model of the digital era. Even though more empirical research should be supported, Michael Porter's diamond model is most suitable for four cases of business models by applying them. Type A sharing outcome with customer is a model that pay differently according to the basis of customer performance. Type B Value Chain Digitalization model provides products and services to customers with faster and lower cost by digitalizing products, services and SCM. Type C Digital Platform is the model that brings the biggest ripple effect. It is a model that can secure profitability by creating new market by creating the sharing economy based on digital platform. Finally, Type D Sharing Resources is a model for building a competitive advantage model by collaborating with partners in related industries. This is the most effective way to complement each other's core competencies and their core competencies. Even though numerous Unicorn companies have differentiated digital competitiveness with many digital technologies in their respective industries in the 4th Industrial Revolution era, there is a limit to the number of pieces to be listed. In future research, it is necessary to identify the business model of the digital age through more specific empirical analysis. In addition, since digital business models may be different in each industry, it is also necessary to conduct comparative analysis between industries

Recently, digital contents systems have been constructed by means of a Web-based Information Systems(WBIS). However, developers supper from the Web Crisis since there is no systematic methodology for development and maintenance of the WBIS. To partially cope with the problem, we propose web-based business process and navigation modeling methods for efficient restructuring of a WBIS. A Business Process Net model is the business process model. Additionally, system structure model, state transition model, and user interaction model are the navigation models. These models might be useful for development and restructuring of a WBIS which includes digital contents.

Digital Media have been advanced and disseminated at the same time around the world. Digital contents have been evolved while Product Technology and Process Technology of 3D Digital Animation and On-line game have completed the innovative developments. First of all, several problems can be occurred when product technology can not lead the evolvement of digital contents. To accomplish the evolvement of both product technology and process technology of digital contents, the whole production system and process system must be modulized. Modulization of system can be completed by the consistent and stable integration of platform. Modulization of production system can bring out the modulization of product technology and then the modulization of technology can speed up the commercialization and market test.
