Overhead transmission line design supporting program using high spatial resolution satellite imagery has been developed recently by Korea Power Engineering Company, The developed program, ITSS(Interactive Tower Spotting System) is purposed to improve the application of satellite imagery with the route selection of overhead transmission line. It is composed of spotting the tower position and designing the tower type and height with DEM(Digital Elevation Model) overlaid with satellite Imagery. To review and confirm the function and work efficiency, ITSS was applied to the pilot project of overhead transmission line design.

A dynamic simulation program of a catenary-pantograph system including tunnel section and transient section is developed in this study. The simulation program can accommodate for the pantograph of two panheads and three d.o.f model. Using the developed program, the dynamic characteristics with a SCHUNK'S WBL 85-PANTOGRAPH is analyzed at the conventional TAEBAEK line and its tunnel section when the catenary system is supported by a tunnel bracket. The simulation results show that the variation of contact force and uplift displacement is allowable in general section and the entrance and exit of a tunnel, but the uplift displacement and the separation ratio within tunnel section is difficult to allow.

The purpose of this study is to find out educational effect of school environmental education utilized school eco-audit. The result of the study is as followings. First, environmental education program based on school eco-audit was developed. Environmental education program was applied school environmental education. According to developed program, students surveyed environmental problem of school and drove to solution of environmental problem. Second, after environmental education, students became to recognize the fact we are responsible for the environmental problem and also affect the solution of it too much. Also, result showed that will to save energy and resource get higher. In conclusion, school eco-audit is effective cultivation of positive attitude for solution and responsibility of environmental problem. Therefore school eco-audit have to introduce school environmental education because school eco-audit derive participation for solution of environmental problem and learning of decision-making.

The objectives of this paper are to estimate differential column Shortening and to determine appropreate compensation amount in 52 story Amatapura Apartment in Indonesia. for this, a computer program based on PCA and CEB-FIP code is developed. The results show that Elastic and Creep strain are the main factors of column shortening and the maximum differential shortening is appeared near the middle of the building height. The results between field survey and estimation have some difference, the most influential factor of the difference can be lateral restraints provided by horizontal members, which cannot be handled in this developed program. Hence introducing the modification factors from various field survey, this program can be used properly in design and construction procedures.

We need general developing environment to control robot with effect but less energy. So, software and hardware tools are very important. In this paper, we present a general-purpose robot control language and its implementation on Real Time O/S and VME bus system. The system runs on the VMEexec Real Time Operating System and robot program is written in the "C" language. The developed program is linked with the robot control C library io produce an executable image. Under the developed robot control environment, the user can write a general high-level control program leaving all the specific information about the robot in a robot specific file.ific file.

Recently, the common concern of nuclear power industry in the development of technology mitigating and preventing the aging of steam generator tubes prevails, because the trends of steam generator flaws at Uljin unit #1,2 and KSNP(Korea Standard Nuclear Power Plant) impose a burden on the operation of nuclear power plant. While the regulatory agency is demanding the establishment of the advanced general performance maintenance system, the steam generator management program adapting advanced technology is being developed which may comply with EPRI PWR SG Guidelines based on NEI 97-06 ‘ General Guidelines including all the maintenance aspects consist of the tube integrity assessment criteria, repair limit, allowable leakage level, water chemistry will be composed in order to obtain the approval of regulatory agency and be applied to Nuclear power plant early 2005. This presentation is to introduce maintenance state including SG tube degradation and main contents of advanced SG management program being developed, and futhermore update present and future plan, and estimate the alternation after the completion.

This study is performed to evaluate and design the vibration characteristics of the onboard machinery with resilient mountings. To reduce the vibration level of onboard machinery with resilient mountings, it is important to evaluate and, if necessary, modify the vibration characteristics of the resilient mountings. In this study, we have developed a program to calculate natural frequencies of the machinery with resilient mountings, forced vibration levels due to internal excitation force of the machinery itself and external excitation forces. of the main engine and the propeller. and the force and motion transmissibility of the resilient mountings. The developed program is also able to be applied to optimal design of the resilient mountings for obtaining a target natural frequency and for achieving a minimum forced vibration level at the center of gravity of the machinery.

The well-known standard normal distribution has been used within the limit of standard variable value of u=3.59. However, the probability values above the limit are not given in the literature. In this study, a probability computation program for standard normal distribution to u=5.99 with the proportional normal distribution a, pp.oximation suggested by Abramowitz and Stegun, Hastings is developed. The new standard normal distribution table developed by the program is presented and will be of help to estimate of probability values for testing and estimation of process mean value, lot acceptable probability, defective percentage of PPM unit of an out-of specification limit, process capability, test power of control charts, probability and statistics.

In this study, on-line measuring system were developed to verify performances and characteristics of electric braking system that is used in KTX(Korea Train eXpress) synthetically and efficiently Because KTX is commercial vehicle, effective measurement and evaluation of measuring signals were performed beyond the range of change for equipment components. KRRI(Korea Railroad Research Institute) described about running-braking measuring program, running-braking backup program and running-braking analysis program that were developed using a software called LabVIEW in this paper. Also, we analyzed the characteristics comparing experimental values with design values about braking distance, braking time, negative acceleration and braking effort in rheostatic braking and regenerative braking. In result, main performances and characteristics for electric braking system in KTX were verified.

In this paper, an optimization program for the design of wiper mechanisms is developed to minimize jerky motion while satisfying design constraints on kinematic and torque performances, mobility condition, and packaging. The lengths/orientations of the links and the position of a driving motor are selected as the design variables. In our optimum design program for wiper mechanisms, an optimization module interacts with an analysis module which calculates kinematic and force/torque properties, until convergence. The optimization results of a particular wiper mechanism are presented to illustrate the effectiveness of the program developed.
