The optimal model is developed to manage and trace the containers in yard. We developed the put-away strategies which considered the storage time for volume of transportation and the distance between blocks and gates using the MICRO-CRAFT (Computerized Relative Allocation Facilities Technique).

This paper describes the NC simulator system for Wire-cut electrodischarge machining. Electrodischarge Wire-cut machining is applicable to all materials including metals, alloys, and most carbides. Although CAM system generate the NC code considering electrodischarge conditions, incorrect Wire-cut tool path bring about fatal results. The simplest way of simulating a EDM process is to display the trajectory of Wire-cutter location by line segments. With this kind of simulation, the programmer can get a general idea about whether the wire is moving as planned but cannot locate gouging or excess material because only the wire location will be seen, not the changes in the workpiece as it is machined. The ideal way of simulating the EDM process is to display the solid model of the workpiece as it is machined. Therefore we propose the ideal NC simulator system for Wire-cut EDM.

In this paper, we purpose the integrated TMS to solve the problem of current systems. Current system resulted in the inconvenience because customer and user must contact to each systems when they want to know the information about the order. In this time, we make the system customer and user can confirm all of order information from one system to solve this problem by integrating the information brought from two systems on constructing integrated DataBase.

Globalization of Economic activities have increased Company's interests about International Logistics Management. Expansion of International trade depends on International Logistics which can overcome distance and time. In In-cheon, There are many small scale and minor Freight Forwarders take advatage of being linked with a port, an airport but their inefficient paper works cause raising of Logistics costs and losing of competitive power. In this study, we develop a web based ocean forwarder information system for freight forwarder to solve these problems. So, this system will provide decreasing operation time, human resources, and accessing easily because of web based system, and finally decrease logistics cost and improve national competitive power.

In the country, already a 400 species and some Interchanges of different Section of Industry have been organized and a number of related industry come to a 4000 species. But in the present, Interchanges of different Section of Industry stay at a form of a friendly society as yet. In this study, we will be helpful to activity of Interchanges of different Section of Industry by concretely suggestion of the utility operation method of Interchanges of different Section of Industry in the many-sided point.

Under WTO we are confronted with the upcoming of the infinite competition and the opening of education market. In order to meet such new changes, more and more university in education industry participate in the certification of ISO 14000. This paper presents an effective approach to obtain the ISO 14001 environmental management system, summarized as follows: First, the top manager should understand the environmental problems and motivate all personnels. Second, a systematized environmental management system should be constructed in accord with actual circumstances of firms, and should be improved continuously by means of effective operation, internal audit and management review. Third, an environmental policy should be published, the environmental programs should be established following an environmental objective, target and they should be monitored regularly.

The four types of management accounting systems(traditional full costing, direct costing, activity-based costing, throughput accounting) are compared in this study. This paper reviews the differences between throughput and contribution margin. The paper concludes that the definition of totally variable cost(TVC) to calculate throughput is situational specific.

This paper reviews differences between the traditional investment evaluation methods and real option approaches. This study considers management flexibility, contingency and volatility from a strategic management perspective. The roles of various real option approaches are discussed.

In the electrode fabrication of unit cell, it was ascertained that electrochemical characteristics were greatly increased with 90 wt.% of BP-20, 5 wt.% of Super P and 5 wt.% of mixed binder [P(VdF-co-HFP) : PVP =7 : 3] The self-discharge of unit cell showed that diffusion process was controlled by the ion concentration difference of initial electrolyte due to the characteristics of Electric Double Layer Capacitor (EDLC) charged by ion adsorption in the beginning, but this by current leakage through the double-layer at the electrode/electrolyte interface had a minor effect and voltages of curves were remained constant regardless of electrode material. The electrochemical characteristics of 2.3 V/3,000 F grade EDLC were as follows: 0.35 m of DC-ESR (100 A discharge), 0.14 mof AC-ESR (AC amplitude 100 mV), 2.80 Wh/kg (3.73 Wh/L) of energy density and 4.64 kW /kg (6.19 kW/L) of power density. Power output was compatible with electric vehicle applications, uninterrupted power supply and engine starter, in due consideration of Ragone relations.

The best Ppy weight ratio was 7 wt% and the optimal electrode composition ratio was 78 : 17 : 5 wt.% of (MSP-20 : BP-20 =1 : 1), (Super P : Ppy =10 : 7) and P(VdF-co-HFP). Implantation of Ppy as the conducting agents have led to superior electrochemical characteristics because of the low of internal resistance and faradaic capacitance. The result of unit cell with Ppy 7 wt% were as follows: 28.02 Fig of specific capacitance, 1.34 Ω of DC-ESR and 0.36 Ω of AC-ESR. Unit cell showed a good stability up to 200 charge-discharge cycles, retaining 82% of their original capacity at 200 cycles. From the analysis of impedance, the electrodes with Ppy 7 wt% showed low ESR, low charge transfer resistance and quick reaction rate. It was inferred that quick charge-discharge was possible. As compared with the specific capacitance (rectangular shape) of CV, it was also concluded that the specific capacitance originated from thecompound phenomena of the faradaic capacitance by oxidation and reduction of Ppy and the non-faradaic capacitance by adsorption-desorption of activated carbon.

The optimum polymer gel electrolyte composition ratio was 23 : 66 : 11 wt% of P(VdF-co-HFP) : PVP =20 : 3), (PC: EC =44 : 22) and TEABF4. And the optimal thickness of polymer gel electrolyte was 50um . The electrochemical characteristics result of unit cell were 31.41 Fig of specific capacitance, and 3.21x10-3 S/cm of ion conductivity. Ion conductivity of polymer gel electrolytes decreased according to added PVP through impedance analysis, and it was higher in 7 wt%, but electrochemical characteristics of unit cell were better in 3 wt% PVP. And for excellent ion conductivity of polymer gel electrolytes, the use of a thin layer electrolyte(20um) was an effective method, but with unit cell application, the best thickness was 50um . Unit cell showed higher capacitance and more stable electrochemical performance when hot pressed between polymer gel electrolyte and electrode. This results from enhancement of the physical contact between the electrode and the polymer gel electrolyte and good accessibility of the liquid electrolyte to the electrode surface.

Railroad line capacity is influenced by Quantitative and Qualitative factors which is applied by parameter to calculate it. But these parameters have been used experiential value without analyzing its reasonability or appropriate level. In this paper, we introduce the concept of robustness to Quantify parameter and evaluate robustness of it. For this purpose, we develop parameter evaluation simulator and present it. If this simulator is utilized, we can find the parameter having appropriate robustness and it will be applied to calculate more reasonable and systematic railroad line capacity.
