In light of the growing traffic congestion problem and congestion cost, the container transport by railway has to be increased. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the DMT(Dual Mode Trailer) transport system which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. The DMT transport will therefore serve the areas required by transport organizers. The purpose of this paper is to estimate economical feasibility analysis for development of DMT transport system. Consequently, this study analyzed the characteristics of the DMT system. The horizontal load.unload system is being considered as an adoptable DMT system in consideration of the situation in Korea.

The private sector is currently reviewing the feasibility of the project or deciding economic policies by analyzing the economic ripple effects. However, the arms acquisition project focuses on the need for the national defense weapons system by analyzing the costs and the effectiveness of the analysis and reviewing the necessity and feasibility of the project. In order to analyze the economic ripple effects, KB (the Bank of Korea) prepares and publishes an analysis table of industrial associations in a given unit. IAAR (the industrial association analysis report) is difficult to apply directly to the defense weapons system. Therefore, research on the economic ripple effects applicable to the defense arms procurement project was needed. In this study, we propose the generic methodology for estimating economical and technical ripple effects resulted in acquiring new weapon systems. Based on the analysis of inter-industrial relations, economical ripple effects are estimated with production inducing effects, value-induced effects, employment-induced effects and export-induced effects. Also, the technological ripple effects are estimated with technological intensity represented by investment cost in research and development. To show the validity of proposed methodology, a case study of acquiring new weapon systems such as GR (guided rocket), destroyer, and helicopter is accomplished. From the case study, it is concluded that these economical & technological ripple effects can be used as a reference to decision making in the course of acquiring major future defense weapons systems.

In order to provide a basic information for the government policy in the future, rice milling costs of Small Capacity Farm-house Rice Whiteners (SCFRW) were estimated by surveying and analyzing the major factors to affect their costs. Two types of SCFRW having one stage and two stage milling process and two rice varieties, Tong-il and Akibare, were considered for their cost estimation, respectively. Also, their costs were compared with those of Private Custom-work Mill in order to determine its economical feasibility. The results were concluded as follows; 1. Major factors to affect the costs were annual milling quantity, purchase price of SCFRW and grain milling loss. 2. Total milling costs of SCFRW were a function of annual milling quantity. These costs decreased rapidly as annual milling quantity increased. 3. In comparison of milling costs between single pass type and double pass type SCFRW, the former was more economical than the latter. 4. Also, in comparison of milling costs between two varieties by using SCFRW, Akibare was less expensive than Tong-il. 5. In comparison with private Custom-work Mill, both single pass and double pass type SCFRW were less economical than private Custom-work Mill. 6. In order to have an economical feasibility, SCFRW should be designed and developed to reduce its milling loss and purchase price.
