In this paper, a new type of cryptographic key recovery mechanism satisfying requirements of business environment is proposed. It is also applied to enterprise information infrastructure for managing employees' task related to handling official properties of electronic enterprise documents exchange. This technology needs to be complied to information management policy of a certain enterprise environment because behavior of cryptographic key recovery can cause interruption of the employees' privacy. However, the cryptographic key recovery mechanism is able to applied to any kind of information service, the application areas of key recovery technology must be seriously considered as not disturbing user's privacy It will depend on the policy of enterprise information management of a specific company.

In this paper, we propose a novel uplink congestion control scheme, which enhances downlink TCP throughput by improving response time of TCP acknowledgements without TCP modification. Through the experimental results, it is manifested that the proposed scheme is able to achieve better downlink TCP throughput.

For a recent most companies to make efficient business management, we are using a groupware service of integrated information system of the entire group. Groupware service integrates the cooperation in excellent synergy and duplicates has been business functions of the business, through the improvement of multi-purpose business processing capacity, there is an advantage of reduced operating costs. However, if the parent company and subsidiary, or to handle common tasks such information agency, which may cause differences in the format of the data passed in the case of a need to provide a document. Therefore, in this paper, in order to solve the heterogeneity problem in data between groups, the data system of the hub base of the cloud is provided. The proposed system is intended to improve the groupware environment including the interoperability of integrated standardized environmental data sharing service.

In general wireless power transfer systems (WPTSs), power transfer is controlled by the wireless communication between a transmitter (Tx) and a receiver (Rx). However, WPTS is difficult to apply in electronic products that do not have batteries, such as TVs. A WPTS with resonators based on a transformer of LLC series resonant converter is proposed in this study to eliminate wireless communication units between a Tx and an Rx. The proposed system operates at the boundary of the resonance frequency, and the required power can be stably supplied to authorized devices even though some misalignment occurs. Moreover, standby power standards for the electronic product can be satisfied.

This research purpose to improve the qualification items for electronic commerce manager. Former qualification system for the electronic commerce manager was executed 11 times from year 2000 to 2005. To improve the standard for test questions and contents of qualification items, we reviewed literatures about job analysis for electronic commerce manager, electronic commerce curriculum, e-Business market and other countries' similar qualification systems and items. We also analysed the job related knowledge, skill, and abilities using job analysis by DACUM method, subject matter experts interview and workshop committee for development and validation of qualification items. Based on the results of job analysis and DACUM workshop, we derived a job model for electronic commerce manager and then validated it through field survey and additional expert review. Finally we developed and suggested an alternated qualification items using matrix analysis between categorized job knowledge and job tasks.

E-business is considered to have the potential of generating considerable new values and the capability to transform the rules of competition in unprecedented ways. This study aim to suggest a approach for new business idea creation. This is based on the analysis and manipulation of business method patents. For this end, our research is performed in the following ways. First, business keywords are extracted from business method patents. Second, business model framework which is used to structuralize the business is suggested based on the literature survey. Third, the business keywords are classified into the business model framework. Forth, existing business model is expressed based on the suggested framework. Finally, new business idea is created from the existing business model by adding, subtracting, or substituting the business keywords.
