Measuring methods of the blasting vibration were generally divided the. manual method and the automatical method. When using the automatical method, field data of the vibration meter can be transferred to a operation computer by using remote equipments. In this study new automatical system using solar power supply is to be introduced. New automatical system is well suited for the field which is difficult to access and is needed frequent measurements of the blasting vibration. And it can make easy to accumulate the data and control the blasting vibration for safe blasting.

The previous exponential experiment system has been improved for the automatical and accurate axial movement of the neutron source and detector with attaching the automatical control system which consists of a Programmable Logical Controller(PLC) and a stepping motor set. The automatic control program which controls MCA and PLC consistently has been also developed on the basis of GENIE 2000 Library. The exponential experiments have been carried out for Kori 1 unit spent fuel assemblies, Cl4, Jl4 and G23, and Kori 2 unit spent fuel assembly, J44, using the improved systematical measurement system. As the results, the average exponential decay constants for 4 assemblies are determined to be 0.1302, 0.1267, 0.1247, and 0.1210, respectively, with the application of Poisson regression.

This paper is describes the measured electric field waveform radiated by lightning discharge. We have performed measurement and analysis of the electric fields associated with stepped leaders. Electric field measurement system was composed of hemisphere electric field sensor, measurement system of a distance from lightning strokes, automatical recording system, A/D board, personal computer etc. A/D board have high sampling time, high speed data processing, 8bit of resolution. Also, measured characteristics of stepped leaders radiated by were analyzed.

그레이팅이라는 금속제품의 자동 설계 시스템인 GDS (Grating automatic Drawing System)는 기본 설계 도면(Plan Drawing)의 정보들을 바탕으로 여러 세부 도면들을 자동 생성하는 시스템이다. 그러나 GDS를 통해 자동 생성된 도면은 설계자들의 일반적인 치수기입 요령을 부분적으로 만족시키지 못하고 있으며 또 치수 표시간의 겹침 현상이 발생하여 설계자가 도면을 수정해야 하는 번거로움이 있었다. 본 논문은 이러한 문제점을 해결하기 위해, 설계 전문가들의 치수 표시법을 지식으로 하여 규칙 기반 전문가 시스템을 구성하였다.

In a large scale robot system, one of important problems is software integration, which involves three elements: modularity, reusability and stability. By these issues, the degree of convenience of system integration, its required time and the performance of the system stability can be determined. In addition, the convenience of system management can be determined by the degree of completion of service components. This paper explains the template based service component (TBSC) for the integration of service components in networked robot. The important characteristics of TBSC are automatical execution and recovery process by a PnP supporting robot framework, which helps a system operator to manage a robot system comfortably. For easy implementation and system stability, we provide a service component creator and a verification tool to developers.

This paper is a study on the management system of data and documents for the LRT Project using the systems engineering approach. It is addressed a computed based management system using the Systems Engineering Approach toward system thinking to manage effectively and efficiently data and documents. Because the unified efforts was insufficient data and outcomes of project management and systems engineering during the existing LRT Project, we proposed the unified computer management system for the project management and systems engineering efforts using the systems engineering methodology like as a operation concept, collection and analysis of requirements, and functional architecture analysis. This will offer supply efficiently data and outcomes management for the LRT project and then support the automatical document publish output.

The backwardness of Domestic security management system tend to depend on foreign security companies which have advanced technology. The appearance risk to flow out confidential affairs of domestic enterprises and public organizations to foreign countries. In this regard, this paper is implement and designed automatic security analysis system for secure public network. This system is to offer enhanced security quality of public organizations and reducing the dependence on foreign companies. And maintains security analysis technique for public network.

To develope the soybean sprouting equipment(a type of cabinet) for medium amount(one bucket; 10~13kg) production of soybean sprouts, the watering system was made of four siphons and four the bottle necked water tank. Diameter of four siphons used for development of the watering system were 8, 13, 17 and 21mm, respectively and their water exhausting volumes were 40, 92, 154, 524ml/sec, respectively. The watering system can be automatically watered 524ml/sec without electric supply. The soybean sprouting equipment is consisted of four the bottle necked water tanks with the four siphons and six sprouting buckets with net shaped bottom for water draining. The soybean sprouting equipment with the watering system may be produced more than one box a day in the condition of 6~7 watering times a day at 25~30oC.

Various display devices become widespread now. Endeavoring to provide high-quality user experience, sharing contents becomes a hot issue in recent years. In this paper, a Contents Sharing System based on Users Context is proposed, which can provide pervasive contents sharing services on multiple devices with disregard for the device differences. This system supporting automatical contents sharing according to users' context, and intelligent content-fault recovery to provide an intelligent platform for users sharing service seamlessly without additional manual operations. Also we points out the problems and considerations about this proposed system which will be improved in the later research.
