The efficient maintenance and management of steep slopes often require excessive professional resources and quantitative investigations. Therefore, it is important to develop technology for objective scientific site investigations and quantitative evaluations of steep slopes. This study proposes a 'Mobile System' for steep slopes in order to improve the effectiveness of site investigations compared with conventional methods using anevaluati on table. By analyzing site investigations and desktop studies, the required software and hardware are identified to develop the 'Mobile System', consisting of a 'Field Information Input System' and an 'Analysis System'. The applicability of the system is verified by its application to an area with steep slopes affected by debris flows. The use of this system is expected to increase the efficiency of maintaining steep slope sand to reduce the time and resources required.

This research was conducted in order to present the strategies of implementing the logistics information system for effective logistics cost management with the case study of a leading global company. The strategy for effective logistics information system can be derived from the 3 different viewpoints, Firstly the effective global logistics management can be insured by means of the efforts of the reinforced total organization. Secondly from the process-oriented perspective, we should recognize the logistics process as the core factor of the competitive strategy and innovate the logistics process itself for the logistics cost reduction. Finally, the logistics cost will be effectively managed through establishing its logistics information strategy which maximizes the utilization of the information technologies. The case study of 'A' electronics company shows that its logistics management system provides the company with various visibilities about its logistics cost and the direct and indirect benefits over billions of wons per year as well. Therefore we can conclude that the research model provided in this research is validated. This study presents the concrete implementation strategies of the logistics information system and verifies the validity of the strategies by means of the case study of a leading company.

The main objective of this paper is to investigate the performance characteristics of a $CO_2$ air conditioning system for fuel cell electric vehicles (FCEV). The present air conditioning system for FCEV uses the electrically driven compressor and electrically controlled expansion valve for $CO_2$ as a working fluid. The experimental work has been done with various operating conditions, which are quite matching the actual vehicle's driving conditions such as different compressor speed and high pressure to identify the characteristics of the system. Experimental results show that the cooling capacity and coefficient of performance (COP) were up to 6.3kW and 2.5, respectively. This paper also deals with the development of optimum high pressure control algorithm for the transcritical $CO_2$ cycle to achieve the maximum COP.
