The aim of this study is to analyze the relationship between fluctuations of a government subsidy and research outputs on the basic research field. An analysis of this study was conducted on basic research projects specifically on the field of information technology (IT) filed at university and Individual Research Programs of Korean ministry. Using various project characteristic variables, relationship between dependent variables and independent variables was controlled. To summarize results of a regression analysis, from looking at the correlation between fluctuations of a government subsidy and basic research outputs (weighted papers and patents), the result showed a positive relationship. The maximum effect of increased research funding projects on research outputs was 8 times greater than an effect of maintained funding projects. Moreover, the maximum effect of decreased research funding projects on research outputs was 4 times greater than an effect of maintained funding projects. Base on this result, we suggested implications from academic and practical aspects.

This study looks at the reasons behind the termination of container transportation between Busan and Incheon in terms of costs structure, the division of profit, and the economic limitation faced in the domestic shipping market. The operation costs have been examined in relation to the components of logistic system of container shipping and the cost function has been estimated. The distribution proportion of operation revenue has been also investigated, considering the different components of logistics activities. In addition, the average revenue of container vessels of 144TEU and 215TEU has been calculated. Economic limitation can be analysed through the optimisation behaviour of shipping companies which tries to maximize profit or minimize loss. In conclusion, domestic short sea shipping can get the economy of scale only by transporting vessels' maximum capacity. It is also vulnerable to trucking market's fluctuation. Without the subsidy for operation, the liner in domestic short sea shipping will stop the service in order to minimize the loss.
