The realization of the Internet and Electronic Commerce through the progress development of the information & communication has changed the transition of the financial settlement system all of the world. And Electronic Commerce has becoming the most important tools to decide the value from the real money, existing bills, coins to the Electronic Money. Electronic Money is very useful materials with Electronic Wallet at cyber times in the future. So that reason, I studied Electronic Money's present situation & after development direction in Korea. And the purpose of this paper is to introduce Electronic Money's modem definition and to analysis the common use situation, operation at home and abroad at Electronic Commerce times. In add to investigated advanced countries Electronic Money utilization and drawed out current events point. So I suggest to this like point, in honour of Electronic Money's common use in Korea. First to establish universality. Second, to make various terminals and the powerful networking structure. Third, to establish stability. Fourth, renovating the system goes side by side. Futhermore, to develop Electronic Money's, it is necessary to make skilled labour and to learn foreign advanced technology.

The situation frequently occurs in which the input torque capacity of the converter should be changed. It is known that the modification of the ou angles of the torque converter elements is suitable for such situation with diameter of flow path of the converter maintained. But so far it has been, predict correctly the converter characteristics as well as the effects of oulet torque capacity in the past numerical methods. In the present numeric introducing the interrow mixing planes, the torque capacity was satifactorily and it was shown that the torque capacity could be effectively changed by the oulet blade angles of pump and stator.

This research paper is to analyze the specific situation for the 157 failure cases of Seoul Metro power cable since 1990 and to consider the countermeasures. This is, also, to prevent accidents by analyzing the current state of each Line, the failure of causes, railroad tracks, installation year, opening year, and monthly failure conditions and by presenting the countermeasures. In addition, this research is to discuss the present installation situation of Seoul Metro power cable, the types of power cable, symptoms, causes and the countermeasures.

The information system fields of spatial applications have rapidly grown during the last decade in Korea. Spatial data has been produced for a variety of systems without common standards until national GIS Committee defined the data exchange formats among spatial databases in the middle of 1990's. It aimed at promoting data sharing between the different systems in similar application fields. However, a considerable number of databases built prior to the introduction of the standards are not yet standard compliant but still play the roles of the main producers/consumers in the data collection field such as early developed huge AM/FM systems maintained by governmental organizations. The strong autonomy of these databases keeps their own data models, formats and descriptions from being standardized, which leads the sharing to a more difficult stage. Sharing is another way of data acquisition with least efforts and time away from direct collection. A data clearinghouse is the core module which directs users to the relevant data resources. The contents of datasets should be described with predefined metadata standards for precise indexing. Moreover, a number of technical problems have to be resolved for the common use of data between heterogeneous spatial database systems. However, the technical issues can be covered by the present information technologies. The difficulties persist in the political/institutional issues. Institutional issues are derived from the diverse sources such as political background, governmental policies, related laws and/or regulations. The paper will firstly make an analysis of current situation in terms of Korean policies, laws and regulations, secondly abstract the institutional issues from the situation analysis, lastly present guidelines for promoting spatial data sharing in Korea.

This paper presents the design and analysis of the electromagnetic system such as jumping ring system. Also, we study the characteristics of dynamics for system with initial parameter. For the propose of system control,, first, we simulate the MATLAB tool solving coupled differential equations with electric parameter, inductance and mutual inductances. Therefore, we design a jumping ring system using design results, implement, and analyze the jumping ring system real situation. For the near time, we present a control process, and compare of real system and software technique.

The present serial cadastral maps, which have lots of problems arisen from map matching processes, have very limited applications. That is, the poor quality of serial cadastral maps has kept us from using them. Therefore, a special project for improving the quality of serial cadastral maps was proposed by korean cadastral specialists to solve those problems. The primary purpose of this study is to provide effective ways of serial cadastral map production by reviewing the errors of the present situation-based serial cadastral map production using GIS and digital orthophoto.

The situation frequently occurs in which the input torque capacity of the torque converter should be changed. It is known that the modification of the outlet blade angles of the torque converter elements is suitable for such situation with the outer diameter of flow path of the converter maintained. But so far it has been difficult to predict correctly the converter characteristics as well as the effect of outlet angles on torque capacity in the past numerical methods. In the present numerical method introducing the interrow mixing planes, the torque capacity was satisfactorily estimated and it was shown that the torque capacity could be effectively changed by modifying the outlet blade angles of pump and stator.
