Maintenance scheduling of generating units (MSU) has strategic dimension in an oligopolistic market. Strategic MSU of gencos can affect a market power through capacity withdrawal which is related to bidding strategy in an generation wholesale market. This paper presents a combined framework that models the interrelation between competitive bidding and strategic MSU. The combined game model is represented as some sub-optimization problems of a market operator (MO) and gencos, that should be solved through bi-level optimization scheme. The gradient method with dual variables is also adopted to calculate a Nash Equilibrium (NE) by an iterative update technique in this paper. Illustrative numerical example shows that NE of a supply function equilibrium is obtained properly by using proposed solution technique. The MSU made by MO is compared with that by each genco and that under perfect competition market.

Although electricity market structures may be different from each country, they have a long-term forward market and a short-term spot market in general. Particularly, a bilateral contract transacted at a long-term forward market fixes the electricity price between a genco and a customer so that the customer can avoid risk due to price-spike in the spot market. The genco also can make an efficient risk-hedging strategy through the bilateral contract. In this paper, we propose a new mechanism for deriving the optimal bilateral contract price using game theory. This mechanism can make the customer reveal his true willingness to purchase so that an adequate bilateral contract price is derived.

This study is aimed to estimate market integration of wild caught fish species on the Korean market, using both multivariate and bivariate cointegration analysis. For the analysis of market integration between wild caught fish species, major four fish species those are most popular fish in the market and caught by the large purse seine fishery-chub mackerel, jack mackerel, hairtail and spanish mackerel-were selected as analytical target fish species. And their real monthly price data from January 2000 to December 2011 were used in the analysis. The results of the multivariate cointegration test for four wild caught fish species showed that there would be long-term equilibrium relationships among prices of four wild caught fish species, and consequently, the markets for wild caught fish species were estimated to be integrated. The results of exclusion test and bivariate cointegration test also supported that there would be a clear evidence to suggest that all target wild caught fish species were cointegrated each other.

Recent Studies have shown evidence of a positive relationship between market orientation and performance. However, some scholars have suggested that customer satisfaction, salespeople's job satisfaction, and product quality etc. could moderate this relationship. According to the increase of market oriented efforts of apparel firms and importance of the salespeople's role, this study focuses on the effect of market orientation on performance of apparel firms through the salespeople's job satisfaction and customer satisfaction. It is found that market orientation has a positive effect on the salespeople's job satisfaction and customer satisfaction. The salesperson's job satisfaction was found to influence on the performance through the customer satisfaction. The customer satisfaction has strong influence on the performance directly. Market orientation appears to provide a unifying focus for the efforts of salespeople within the organization, thereby leading to customer satisfaction and superior performance.

But the Key success factors Korean films in the foreign markets are the improvement of contents Quality and the diversification of trade market. Namely, Our films is mainly exporting Japanese market and the import depends upon American films. In case the trade specialization index(TSI), The international competitiveness of Korean films shows lower import specialization, by virtue of export increasing of Japan, Europe and other markets in 2000's. On the other hand, The Export Market Share has shown similar pattern to main markets except Japanese market, and the import was almost similar to trend in foreign markets except American films. Consequently the present film strategies and polices that delight limited markets will not be compete in global markets, Korean films or contents is merely called by that name.
