Since Cost Based Pool markets has been continued to power markets, Genco. needs economic analysis about investment in power plants. Particularly most Private Genco.s have presently a construction plan about LNG combined cycle thermal power plants. In this paper, we propose a economic analysis method of LNG combined cycle thermal power plants using Economic Dispatch and Optimal Power Flow in CBP markets. Also we develope computation model using it for decision making to build a plant. This method can consider a variation of power facility like power plants and transmission lines in CBP markets. Finally, this dissertation provides a relevant case study to confirm the effect of cost factor to economical efficiency.

??The temperature of the body is determined by the temperature of the water, the swimming speed and the percentage of the subcutaneous fat. For this specific experiment, we asked the testee bring out the maximum exercise of their own and as a result, the load swimming speed and the percentage of the subcutaneous fat remained constant. Therefore the main factor that determines the temperature of the body is the temperature of the water. So to speak, the temperature of the body for the testee group and the controller group went down as the temperature of the water went to 33℃~23℃.<br/> ??As the temperature of the water went down, it slowed down the muscular movement and decreased the consumption of air below to the maximum. The skin, however, deemed to prevent the lowering of the temperature of the body. As a result of this experiment, it is assumed that the primary factors for the changes in VO₂nax were caused by the coordination of breathing, circulation, and the muscles.

The purpose of this study was to investigate the effect of administration of L-arginine on rating of perceived exertion and fatigue material during endurance exercise. Methods : The subjects of this study were six elite swimmer. All six swimmer were performed to do cycle ergometer exercise in the laboratory and it has been measured repetitively in 6 weeks of interval. Each experimental exercise were monitored and analyzed the change of fatigue material. Rating of perceived exertion decreased significantly in L-arginine administration group than in placebo group at 50 min and 60min(p<.05). The amount of lactate concentration decreased significantly in L-arginine administration group than in placebo group at 45min and 60min(p<.05). The amount of ammonia concentration decreased significantly in L-arginine administration group than in placebo group each time blood sample was collected(p<.05). therefore, These results show that L-arginine administration could increase exercise performance and decrease fatigue material in endurance exercise.

Korean Criminal Law was revised eight times so far this year since it was established in 1953. Criminal Law Revisions in the field of crimes against property were three times: the third revision (1995), the fifth revision (2002) and the seventh revision (2005). In this way, it`s rare to revise crimes against property in Criminal Law. The object of this study is the field of crimes against property in Particulars of Criminal Law. But, in order to limit the range of the discussion, it is not be studied all regulations of the field of crimes against property individually but be studied only some regulations that intimately connected to one another in the field of crimes against property. This study considers the trend of the Criminal Law revision(Ⅱ) and proposes developmental strategies of the Criminal Law revision from now on(Ⅲ). The efforts for the total revision of the Criminal Law still exists. The government (Ministry of Justice) and the relevant academic societies pull out all the stops to revise the Criminal Law. It is expected to be proposed Criminal Law Revision Draft(a government bill) that is the fruit of their efforts before long.
