It has been a basic model for the present electric power industry that more than two generators compete, and thereby the market clearing price and the generation schedules are determined through the bid process. In order for this paradigm to be applicable to real electric power systems and markets, it is necessary to reflect many physical and economic constraints related to frequency and transmission in the dispatching schedule. The paper presents an approach to deriving a Nash bargaining solution in a competitive electricity market where multiple generators are playing with the system operator who mitigates the transmission congestion to minimize the total transaction cost. In this study, we take the effect of the line flows and the role of system operator into the Game. Finally, a case study has been demonstrated to verify the proposed cooperative game.

Degradation of structural carbohydrates has been observed in samples of sweet sorghum inoculated with either Clostridium cellulolyticum or Bacteroides succinogenes. However, conditions under which these rellulolytic organisms can compete effectively with lactic acid bacteria have not yet been determined. Degradation of cellulose by B. succinogenes was found not to be inhibited by either glucose or succinate.

It's became essential that Korea construction companies should enter into the overseas construction market for their growth and sustainability. In order to comply with the client's required global standard and to compete with in the international market, the shifting the construction project management system to global level is required. In accordance with the demand, this paper proposes the top-level document of construction project management system as a to-be model that utilized in overseas construction projects. The project management plan ("PMP") suggested in this paper is not only the most appropriate one, which complies with the global standard, to be used when companies bid for international construction projects against foreign competitors but also has the process modeling and hierarchical structure.

The mobility of sulfate in soils defends on several factors including redox potential, soil mineralogy, pH, and the presence of other anions that compete for sorption sites with sulfate. The proposed model of adsorption mechanism for sulfate postulated that reaction is between anions in solution and charged surfaces of soil particles. With appropriate choice of parameters obtained from the adsorption-desorption experiments, the equation of transport model adapt an empirical approach, capable of handling most general equilibrium adsorption isotherms, suitable for multispecies systems.

The fundamental problem of communication is that of transmitting a message from a source to a destination over a channel through the use of a transmitter and receiver. To derive a theoretically optimal solution, the transmitter and receiver can be divided into several processing blocks, with each component analyzed and optimized. The idea of machine learning (or deep learning) communications systems goes back to the original definition of the communi-cation problem, and optimizes the transmitter and receiver jointly. Although today's systems have been optimized over the last decades, and it seems difficult to compete with their performance, deep learning based communication is attractive owing to its simplicity and the fact that it can learn to communicate over any type of channel without the need for mathematical modeling or analysis.

This technical paper presents future missile trends and propulsion technologies necessary for the missiles. The views are based on open literature briefings of the United States and internet informations. These informations let domestic incorporations prepare technologies for the future. Political and economical environment has been changing worldwidely. More extensive role is required for the incorporations to increase the economic growth of our country. The incorporations should establish the long term product development strategy of their own to compete with foreign countries.

The purpose of the research is to discuss the product safety procedures for the food area. The producer and supplies of the products should be able to satisfy the needs of the increasing consumer safety. The products, for the purpose of developing and making safe products, must perform Hazard Finding and Risk Analysis to detect potential danger to mike sure the final safety measures are in place. The purpose of Product liability rests finally with the consumer safety and the manufacturer's capability compete in the marketplace. Especially this is important for the food industry. But, our domestic middle and small food industries, it is relatively weak in this are. Thus this research would like to present a easily usable product safety procedures.

The effect of polyamine and Ca2+ on D-glucose-6-phosphate cyclohydrolase activity was studied in Daucus carota root. The enzyme activity was reduced in response to increase in concentration of Ca2+, not the Ca2+-calmodulin complex. The inhibition effect due to Ca2+ was reversed by polyamine, especially remarkable at low concentration of Ca2+. The effect of the Ca2+ on the enzyme seemed to compete with polyamine according to the Lineweaver-Burk plot. The enzyme activity from carrot root protoplast cultured in the prescence of verapamil was higher than that of the control. Such cumulative results suggest that the inhibition by the Ca2+ and enhancement or reversal by polyamine could regulate the biosynthesis of pectin and hemicellulose to some extent.

A Study on the strategic methods for internal marketing of Family Restaurant. We know that customer satisfaction in measuring the effect of marketing performance on employees in service industry. There are four strategies of internal marketing for service-employee, which are participation-promotion and manner-management of employee, classification to employee, communication strategy, motivation environment for employee. First, communication, sales and service technology of employee can be developed and improved through the education and training. Second, company can make better achievement by classifying life-style and individual desire. Third, communication strategy can improve service quality by development of team-work through the confidence and joint-responsibility. Fourth. the company make environment which employee can compete by offering incentive fairly and properly. In the conclusion, when employees serve customers in a depressed attitude, they neglect service process and bring about customer non-satisfaction. This have negative effect on external customer satisfaction in the short term. And so that customer-satisfaction can't exist without employee-satisfaction. that is job-satisfaction is the goal of company. therefore study about internal marketing action should be go on.

Nowadays, customers of the Foodservice want to receive high quality service from foodservice enterprise and their expectation is affected by high income and glottalization. In addition, the development of the Foodservice Industry shows the trend to contain much economical theory due to the change of their environment. Foodservice enterprise are to coming complicated and complexes and it's getting harder to compete with others, They are trying to make new strategy when they give goods to their customers. On the way to the moment of offering services, they include the wide and special ranges from the culture to the diplomacy, compared with other maunfacturing firms. It needs more people and their better cooperation, when managing the hotel company. Their's the particular characteristic of the Foodservice Industry
