Innovators Market Game is a method for facilitating innovation by helping to create new ideas by combining existent ideas. In this game, participants play roles, think of new ideas and evaluate them. The roles are selected from the real world, e.g., police officers, transportation authority, government and so on. The Role-based Innovators Market Game proposed in this study is designed to lead innovative ideas, based on the defined factors. Its rules, acting roles, and the communication in the Ro

With the emergence of global platforms for trading and buying/selling data, data have become a profitable commodity. The growth of such platforms has necessitated the further expansion of the scope of data in digital economies. To this end, understanding the nature of available data and their relationships between them has become an important challenge for expanding their use. Thus, in this study, we assumed data on the platforms as a population and metadata as the samples. Thus, we quantitative

Improvements in Web platforms for data exchange and trading are creating more opportunities for users to obtain data from data providers of different domains. However, the current data exchange platforms are limited to unilateral information provision from data providers to users. In contrast, there are insufficient means for data providers to learn what kinds of data users desire and for what purposes. In this paper, we propose and discuss the description items for sharing users’ calls for data

The contribution of ionized and unionized species to the overall permeation of weak electrolytes through the skin was investigated to determine the effect of pH in the vehicle on the permeability of indomethacin (IDM), as a model drug, through hairless rat skin. The permeability of IDM through polydimethylsiloxane (silicone) and poly(2-hydroxyethyl methacrylate) (pHEMA) membranes which may reflect lipid and aqueous pathway, respectively, was also measured for comparison. As the pH in the vehicle

In recent years, data have been treated as economic goods, and have begun circulating into new forms of the ecosystem through data exchange. The increasing expectation that data exchange will be used to create new businesses and economic value requires a strong understanding of the overall structure and the characteristics of the data exchange ecosystem. However, unlike other well-known business ecosystems, such as the financial markets or service ecosystems, the data exchange ecosystem is immat
