Google Trends is a useful tool not only for setting search periods, but also for providing search volume to specific countries, regions, and cities. Extant research showed that the big data from Google Trends could be used for an on-line market analysis of opinion sensitive products instead of an on-site survey. This study investigated the market share of tumor necrosis factor-alpha (TNF-α) inhibitor, which is in a great demand pharmaceutical product, based on big data analysis provided by Google Trends. In this case study, the consumer interest data from Google Trends were compared to the actual product sales of Top 3 TNF-α inhibitors (Enbrel, Remicade, and Humira). A correlation analysis and relative gap were analyzed by statistical analysis between sales-based market share and interest-based market share. Besides, in the country-specific analysis, three major countries (USA, Germany, and France) were selected for market share analysis for Top 3 TNF-α inhibitors. As a result, significant correlation and similarity were identified by data analysis. In the case of Remicade's biosimilars, the consumer interest in two biosimilar products (Inflectra and Renflexis) increased after the FDA approval. The analytical data showed that Google Trends is a powerful tool for market share estimation for biosimilars. This study is the first investigation in market share analysis for pharmaceutical products using Google Trends big data, and it shows that global and regional market share analysis and estimation are applicable for the interest-sensitive products.

B2B transaction was expected to dominate in the global market and thus many e-marketplaces have been built since 1999 in Korea. However, only a few e-marketplaces are thriving and the future of B2B e-marketplaces except MRO area seem to be uncertain. This paper explores why B2B transactions only in MRO area are rapidly increasing and examines the competing structure and business models of MRO e-marketplace. Business models of MRO e-marketplaces are various among different countries. However, they can be classified as three business models:information portal model, purchasing agent model, open market model. It is not easy to answer which business model is most competitive because each models have their own advantages and functions. Information portal model can be easily applied for the e-marketplace which operates off-line enterprises. Purchasing agent model is favorable to the e-marketplaces which has already obtained buyers and sellers. Open market model is desirable to the e-marketplace which has excess to global market.

The current pricing policy on the UCC market is the fixed pricing, which is set by the seller once and price never changes again. However market demand and supply are changing hourly, so the studies about dynamic pricing to determine more properly have been carried out. This paper suggests dynamic pricing models for UCC by analyzing the customer's searching pattern. We propose 2 pricing models (trend change-based pricing model and relative pricing model), and experiment various status by controlling system and market variables. We demonstrated our model by computational modeling and simulation. The result of this research can be useful guidelines to increase the revenue and profit of the UCC Market.

The recent movement to deregulated and competitive electricity market reacquires new concepts against existing central dispatch in the system operation and pinning. As power systems tend to be operated more closely to their ultimate ratings, the role of SCOPF (Security Constrained Optimal Power flow) is changed and the importance for real-time security inhancement will be more increased i]1 the new and com partitive electricity market. This paper deals with the application of the SCOPF which makes possible the On-Line application. The security margin of power system truly is changed according to the conditions or configuration of power systems, therefore, the sensitivity factor reiated to the security is recalculated and the application should be updated in accordance with the state of power system. The goal of this paper is to obtain proper security through the effluent usage of the sensitivity and to apply this a1gorithm to system operation. The proposed mechanism has been tested on a sample system and the results show more secure conditions against critical contingencies.
