Teachers' beliefs about teaching English are reflected in their practices in the classroom. They influence on the students' attitude to English learning. Any teacher training program expects the trainees to change or modify their existing beliefs and attitude through the new ideas and information introduced by the program toward a desired direction. The present study describes a teacher training program for elementary school English teachers and compares the beliefs of the teachers about teaching English before and after the training. The subjects are the elementary school English teachers around Chungnam area who get a special training of 120 hours during January 1997. The investigation of the subjects' beliefs on English teaching is conducted through examining two journals of each subject before and after the training. The journals show the teachers' inner flow of thought, so teacher trainers are expected to get insight on their general instructional considerations and have implications on the future teacher training program through examining these journals. In addition, the journal writing itself gives the teachers opportunity to reflect their practice and rethink about their beliefs, and develop themselves as professional English teachers.

Several strategic system are prepared and designed for the critical technology-21, which is a kind of national R&D program and is based on the $\ulcorner$Special Act for Innovation of Science and Technology$\lrcorner$from early of 1998. Various valuables in social-technological, political-technological and econo- technological points and a new R&D planning method, "scenario method, " are considered and tried for overcoming the socio-economical difficulties of country and strategies of this program which is become a implementation skeleton of critical technology-21 are summarized as a implemental model of national R&D program. And present states, sub-projects of same research program are analyzed by type of research group and valuables.

This report will introduce the epitome about the subject, HANARO (Hi-flux Advanced Neutron Application Reactor designed by KAERI in early 1995) Utilization Education Training Program Development and Operation, which is one of the nuclear research basic expansion businesses executed from 1999. 12. to strengthen the usage of HANARO. This program consists of the basic reactor experiments program for university students who have specialty of nuclear and other engineering, and the special research education program for faculties from universities and researchers from industrial fields. Principle lessons are reactor operation, radioisotope production, neutron activation analysis, neutron radiography, radiation shield (health physics), nuclear fuel combustion measurement by gamma scanning arrangement, and CNS (Compact Nuclear Simulator) and so on.

A graphic vehicle modeling pre-processing program and a visualization post-processing program have been developed for AutoDyn7, which is a special program for vehicle dynamics. The Rapid-App for GUI(Graphic User Interface) builder and the Open Inventor for 3D graphic library have been employed to develop these programs in Silicon Graphics workstation. A Graphic User Interface program integrates vehicle modeling pre-processor, AutoDyn7 analysis processor, and visualization post-processor. In vehicle modeling pre-processor, vehicle hard point data for a suspension model are automatically converted into multibody vehicle system data. An interactive graphics capabilities provides suspension modeling aides to verify user input data interactively. In visualization post-processor, vehicle virtual test simulation results are animated with virtual testing environments.

Recently it is used seismic analysis like single mode spectrum analysis, multi mode spectrum analysis and time history analysis in Korea. Because bridges are not special form of them but regular and simple form of them in our country, we must develope seismic analysis program of bridge based on single nude spectrum analysis. The program developed by this study reduces a Quantity and a time of calculation compared to SAP90 and gives accurate answers without errors. In the case of commercial program if we look for seismic load(P/sub e/(x)), we must increase the number of node and the larger the number of node the more a quantity and a time of calculation. But this program is exactly solved with basic node compared to commercial program.

Risk assessment of a railway system should be periodically conducted managing a large amount of accumulating accident/incident data and scenarios, which generally requires enormous time and efforts. Therefore, special information management system is essential for railway risk assessment, where data needed for decisions on managing the railway safety could be promptly supported. The objective of this study is to develop a railway accident analysis program for risk assessment. The program is application running on the web which links railway accident analysts throughout the railway industry to a central database. Data entered, together with associated code tables. is stored on MS-SQL database. The program uses the concepts of accident, safety events, causes, related factors(vehicle, person, infrastructure, tool/equipment), recommendations to bring together the various elements of railway accidents. The program will be useful in finding hazard conditions, accident scenarios, quantitatively assessing the risk, and providing pertinent risk measures, eventually serving to prevent railway accidents and reduce severities of railway accidents.

Current finite element analysis programs for soil cutting process with tillage tools require mainframe computers. Several special treatments in developing a microcomputer FEM program were introduced to increase the capacity for solving large problems and reducing the total time cost. The program was evaluated by solving one 3-D example on a 489 microcomputer. The results showed a close agreement with the laboratory soil bin test.

The aim of this short paper is to show some rigidity results for the actions of certain finitely presented groups by homeomorphisms. As an interesting and special case, we show that the actions of Higman-Thompson groups by homeomorphisms on a cohomology manifold with a non-zero Euler characteristic should be trivial. This is related to the wellknown Zimmer program and shows that the actions by homeomorphism could be very much different from those by diffeomorphisms.

Optimality conditions are derived for a nonlinear fractional program in which a support function appears in the numerator and denominator of the objective function as well as in each constraint function. As an application of these optimality conditions, a dual to this program is formulated and various duality results are established under generalized convexity. Several known results are deduced as special cases.

There are many railway structures which were designed without conidering aseismic capacity. In special, masonry structures constructed long time ago should be reviewed about their resistance to earthquake. In this paper, technique to evaluate the capacity of masonry railway bridge is tried to develop by means of FEM analysis. In general FEM analysis program, 3-D solid element is used for masonry structures and response spectrum analysis procedure is tried. In addition, 3-D solid element has material properties equivalent to mortar-brick composite body. Used FEM program is ABAQUS-CAE.
