  • Recently, as the internet speed is getting faster, in the cloud environment, the service receiving device is changing from a general PC to a compact device such as a mobile phone or a tablet PC. Since handheld devices such as mobile phones or tablet PCs are often used in wireless rather than wired, there are many problems that personal information may be exposed maliciously from a third party. In this paper, we propose a user privacy protection scheme through a duplicate duplicate key generation process which can safely protect user 's privacy from third party among cloud services being served through various wireless media. The proposed scheme is used to synchronize the duplicated key between the server and the intermediary device, and aims at shortening the time of the authentication process protecting the user 's privacy. In this case, the proposed scheme uses Interleave() function and random number to synchronize the server and the intermediary device, so it can safely prevent the malicious attack of the third party.

  • Rooted in the work of Pierre Bourdieu, the cultural intermediaries have recently developed as a focus of attention for the Anglo-saxon sociology of culture and cultural studies. This paper tries to critically examine the debate around the definition and role of cultural intermediaries. It also explores the applicability of the notion ‘cultural intermediaries’ to a changing digital mediascape. In the first part of the paper, I clarify the critical problematics inherent in the Bourdieusian conception which focuses on the function of cultural intermediaries for the ‘production of the belief’ in cultural goods. Consequently, I draw attention to the mediation and transformation process of ‘legitimate culture’ by critics in mass media as ‘new cultural intermediaries’. In the second part, I attempt to constitute a typology of cultural intermediaries, proposing the notion of ‘on-line cultural mediation’ and ‘on-line cultural intermediaries’. I also outline the characteristics of three different types (‘traditional’, ‘new' and 'on-line') of cultural intermediaries. I argue this new conception of cultural intermediaries can help to understand the complex power relations and their transmutation in various cultural fields under digital environment.

  • Vertical e-Marketplaces have been expanded because of their enough funds and purchasing power, while horizontal e-Marketplaces have not been grown. On the e-Marketplace which is dealing electronic components with the characteristics of short life cycle and diversities, if an e-Marketplace participant holds a large quantity of the same kinds of components, it will result in lowering competitiveness of the company because of its unuseful inventory. Therefore, as a method for increasing competitiveness of e-Marketplace participants, we proposed the inventory sharing method among the participants, and then designed and implemented it in this paper. For providing inventory sharing function, the e-Marketplace system needs intermediary because each system of participants participating e-Marketplace uses its own DBMS respectively. In this paper, we implemented inventory sharing function using XML, which is a standard for exchanging data, as intermediary, and showed an example of the implemented system.

  • As we increase installing computers, traditional commerce by paper document is replaced by Electronic Commerce, paperless document commerce. Electronic Commerce proves to be an intermediary for increasing efficiency on work, which makes us use it more. This study aims to contribute to streamline local export by analyzing trade firms and manufacturers' using status of Electronic Commerce on work in Pusan. I sent questionnaires to 202 firms working on trade in Pusan to do survey. The sample of this study consists of 96 of them. I analyze using status of Electronic Commerce on work based on those data. The result shows that the more the firms install facility to be able for Electronic Commerce and the better they understand Electronic Commerce related laws, the more they select that on work. Generally The firms in Pusan rarely select Electronic Commerce on work and even acknowledges how much that is needed on work. Considering all of them, this study shows the method of streamlining local export by Electronic Commerce as follows; First, all kinds of Electronic Commerce such as trade related site in Internet should be systemized. Second, the laws on Electronic Commerce should be established in details. Third, workers on firms should be educated on Electronic Commerce. Forth, the firms should install the facility for Electronic Commerce, assist financially and make marketing strategy for selecting Electronic Commerce on each step in work. In conclusion, export in Pusan would be streamlined when the use of Electronic Commerce, effective intermediary, is motivated and we take that method to use on work properly.

  • We are seeing a shift of the focus of information service from system-centered(data-centered or intermediary-centered) a n.0, pproach to user-centered a n.0, pproach. Sense-making theory is one of the user- centered a n.0, pproaches. This study focused on user-centered information service paradigm concepts of Dervin's sense-making theory and interpreting sense-making theory in the practical context of library services. The sense-making theory is basically a cognitive a n.0, pproach to information-seeking, in that it recognizes information as something that involves internal cognitive processes. The user of information becomes the focus in this sense-making model. The sense-making theory sees information as subjective, situational, and cognitive. It focuses on understanding information within specific contexts and on understanding how information needs develop and how they are satisfied. It regards the user not as a passive receive of external information but as the center in a active, ongoing process of change. It related to the information needs of users. Dervin's method for studying information needs employs the 'situation-gap-use' metaphor. All information needs stem from a discontinuity or 'gap! in one's knowledge. Dervin believes that information needs can be addressed by understanding the process that each individual goes through in experiencing a gap, in trying to resolve it, and in gaining something (especially new knowledge) from the experience. Sense-making is a process; 'sense' is the product of this process. Sense includes 'knowledge'. However, it includes a host of other subjective factors that reflect an individual's interpretations of a situation including intuitions, opinions, hunches, effective responses, evaluations, questions, etc. For several reasons, however, difficulties are encountered if one attempts a more substantial assessment of the theory. First, it has not yet crystallized into a well-defined theory. Secondly, though the theory has aroused general interest, e.g. within LIS, detailed discussion of its strong and weak points is still lacking. A third source of difficulty is that the basic assumptions of the theory have been explicated metaphorically. If sense-making theory is to be really useful, it needs to be interpreted for library settings. But we have found no attempt to construct an information service based on the theory. Because the research tradition is still relatively young, there are many unanswered questions connected, e.g. with the design of information systems. In any case, e.g. intermediary access systems would be more efficient and effective it their planning could be founded on the user-centered a n.0, pproach.

  • The emergence of collaborative learning to the public is to tackle the user's privacy issue in centralized learning by bringing the AI models to the data source or client device for training Collaborative learning employs computing and storage resources on the client's device. Thus, it is privacy preserved by design. In harmony, blockchain is also prominent since it does not require an intermediary to process a transaction. However, these approaches are not yet fully ripe to be implemented in the real world, especially for the complex system (several challenges need to be addressed). In this work, we present the performance of collaborative learning and potential use case of blockchain. Further, we discuss privacy issues in the system.

  • Data plays an ever greater part in the tourism industry. While the platform-based sharing of open public data, private-sector intermediary platforms, and the use of social media to understand consumer trends are already well recognized, more potential for innovation exists in sharing private data among organizations in Smart Tourism Destinations. Research into the factors enabling and hindering coopetition in this kind of data sharing platforms is still in the nascent stage of development. Our case study of Sapporo, a major Japanese city endeavouring to create itself as a Smart Tourism Destination, sheds light on the initial approaches to involve organizations to such a data sharing agreement. Founding on seven interviews with ten participants of Sapporo Smart City project organization (SARD), we derived enablers and impediments that promote coopetition in data sharing as part of Smart Tourism Destination development. We also present practical recommendations and future research opportunities for such initiatives.
