Objective: To explore correclational relationship between the risk factors and medical resources consumption in cardiovascular disease patients. Methods: A database containing 44940 cardiovascular disease patients in a southern Taiwan Medical center from year 2003 to 2005 was chosen as studying sample. By applying Charlson Comorbidity Index as one of the major risk factors to these cardiovascular disease patients, then using liner regression to analyze the data for their relationship with medical resources consumption. Results: Medical resources consumption increases as the cardiovascular disease patients become older. The higher the comorbidity index weight with the patient, the more the patient consumes medical resources. A patient¡¦s comorbidity index weight has great influence to the length of hospital stay of the patient and the frequency of clinic visit of the patient. The higher the comorbidity index weight a patient he or she, is likely to stay in hospital longer or to see doctors more often. The variance inflation factor (VIF) of each independent variable is ranged between 1 and 1.343, which means there are no high correlations between independent variables in the modes. In other words, there is no correlative influence effect that would invalidate the assumption. Conclusion: The findings of this study can be a good reference to hospital disease management. In addition, they can be applied to predicting the risk factor in medical resources consumption. Also they can be adapted into medical insurance payment system, thereby improving medical resource distribution.

Abstract Steel is the mother of industry, and is also an energy consumption intensive industry. Especially for the rolling mill, the energy consumption in a reheating furnace take a half, so to save energy in a reheating furnace and reduce the energy consumption become the major issue in the future. The reheating furnace used in general process of steel producing can divided into two types-Continuous type and Batch type- through its ability of steel rolling¡Napproach and its demand. In this thesis, our research target is the batch type reheating furnace, we based on theory of heat transfer in a reheating furnace to build a simulation system of reheating furnace and calculate the temperature-time curve of slab and its heat flux. And then we use the thermal balance model to analysis the situation of fuel consumption. According to different operated conditions, we want to discuss the relationships between energy consumption and increasing temperature of slab inside furnace¡Nsoaking degree¡C From analysis result, we can find that fixed the total time in furnace, the longer of heating time is, the lower of average temperature of slab and the higher of temperature difference of discharge slab are. But in the process of increasing temperature, the max temperature difference of slab is lower. Using the exhaust gas to preheat air through the heat exchanger, we can find that when the temperature of preheated air is increasing, the heat loss of exhaust gas and fuel consumption will be lower. When air-fuel ratio is getting higher, the temperature difference in the process of increasing temperature will be getting lower, and it will be higher as the slab soaks. When air-fuel ratio is increasing, the quantity of fuel consumption will increase too. In respect of refractory material, heat loss of furnace and accumulation of heat in refractory material caused by using the refractory cottons is less than using the refractory bricks. Besides that, the different fuel will only affect the quantity of fuel consumption, not increasing temperature of slab and soaking degree.

The aim of the paper is to investigate how the dual brand of firm decides its optimal allocation of advertising and fundamental strategy of marketing under taking account of markets with multi-consumption externalities. We assume that the market is multi-consumption externalities, and advertising may function as a device to coordinate consumer expectations of the purchasing decisions of other consumers, which is different from the past assumption that consumer type is single and role of advertising in market. Therefore, we reexamine the firm with optimal allocation of advertising. Finally, we show that the firm will adapt different pricing, allocation of advertising and strategy of marketing when facing the different consumer type of combination proportion. If market is dissimilar consumption externalities, above statement will be more significant; On the contrary, if firm facing similar consumption externalities, the optimal is single strategy. In other words, it is independent to consumer's type of combination proportion.
