The purposes of this primary study are the selection of rail station and train operation management techniques for express-rail operation service at the convectional railway electrification. For these analyses, we used the KNR statistics and KROIS data of rail stations and train users by rail line. Therefore, we chose the important stations for express-rail operation of Kyongbu conventional rail line (esp. Seoul-Jochiwon section) through the rail transportation demand. and then, suggested primary operational management plan thorough the effects analyses of decreasing total travel time and increasing transportation demand by train speed-up. This study has some bounds and limits for proceeding, as it does, we excluded as followings: the conditionals of fate system, headways and train diagram, economic/financial analysis and technological assessment, and other railway technological infrastructures and a certain railcar specification, etc. . We propose to enlarge this study into a feasibility study of express or skip-stop operation service and compatible vehicle system decision considering with the best possible investment rail line, furthermore. in front of Kyongbu (Seoul-Busan) high-speed rail open in 2004, we have to try to progress the efficiencies of railway operation applying various train operation management plan.

This study attempts to develop indices in order to make an objective and effective evaluation of achievements in the first stage of operation of the Rural Village Development Project(RVDP) (the first 3 years of its operation). The results are as follows 1. Evaluation purposes are expansion of income-generating bases, improvement of living environments, strengthening of village's competence and establishment of an effective project's management system. 2. Evaluation items for the first three evaluation purposes, which are income-generating bases, improvement of living environments and strengthening of village's competence, are record of performance and substantiality in project's operation, results from operation, and capability in managing the project. Those for establishment of an effective project's management system are participation of habitants and the projects's management system. 3. As this study aims to develop the indices which can evaluate the state of operation in the interim of the project's operation and outcomes generated by then, the evaluation indices are selected by considering those criterions of representativeness, accessibility, usefulness and reliability. 4. As the indices developed in this study efficiency evaluate the process of project's operation and thus evaluate basically the project's operation on the basis of its efficiency. But, considering the purposes of the RVDP, it is included for the overall project's management system and plans for managing activities of the project to be evaluated on the basis of effectiveness.

National defense research and development is trying to develop the weapon system to satisfy users' requirements at minimum cost, high quality and the shortest period. Under integrated database computer environments, development processes and tools have been developed to implement system engineering and concurrent engineering systematically. In the aerospace defense weapon system, the fixed wing development department has developed and operated the integrated operation and management information system based on web technology to manage efficiently the technical information generated by the R&D process. When this system was applied to the existing R&D project for the aircraft weapon system, it proved and verified its efficiency. In this paper, we describe the future development plan of an integrated R&D framework and an integrated weapon system database based on the integrated operation and management information system which are able to centrol the technical information of KF-X, UAV(Unmanned Aerial Vehicles) and UCAV(Unmanned Combat Aerial Vehicles) programs. We also describe an interoperability and integration plan with WISEMAN which will be operated soon in our research Institute.

Line operation safety audit (LOSA) is the proactive data collection system to capture the accident and serious incident caused by flight crew and is the safety management program for collecting threat error management (TEM) and crew resource management (CRM) during normal operations. The typically LOSA is written by hand, manages and archives the LOSA Observation Worksheet. But, this method is not easy to archive and ensure confidentiality of the LOSA worksheets. As we implemented the K-LOSA of the web-document type instead of the existing LOSA archive method and change the TEM category code. we yields to archive the efficient data management and confidentiality. In this paper, we introduce the LOSA and to configure the K-LOSA program.
