This study is to develop assessment framework, test items and questionnaire for the National Assessment of Educational Achievement(NAEA), which administered in the elementary and secondary schools across the country in this year(2000). According to the first year study result of the NAEA, the test was administered in two core subjects, Mathematics and Social Studies. In this study, test items and sets of questionnaire and administered pretest were developed in the last year. In this year, the NAEA was administered with the adjusted test items and questionnaires and the results was analyzed and would be reported to the public. NAEA was developed on the basis of national curriculum, especially of the nature and objectives of subject curriculum in Mathematics (and also Social Studies). In the framework of assessment, we set up four differentiated levels of student achievement: 'under basic', 'basic', 'intermediary', and 'advanced'. Here 'the intermediary level' means the level of educational achievement in which students can understand average content of subject curriculum. 'Advanced level' indicates the level of educational achievement in which students master all the content of subject curriculum and apply basic concepts and principles to a variety of situations. 'The basic level' means the level of educational achievement in which students do not achieve the intermediary level. Students who do not understand average content of subject curriculum are classified as belonging to the basic level. Finally, this study would explain how to administer and analyze the test in the future. The test result was analyzed to report students' educational achievement according to regions, content areas, behavioral characteristics, and etc. This study would show how to report test result\ulcorner and how to set up students' academic achievement.

Recently, studies have been actively conducted on seismic design and improvement of the seismic performance of bridges, buildings, factories, and plants. In particular, heavy items that are being manufactured or waiting to be shipped from factories (such as generators, engines, and boilers) must be equipped with seismic stoppers to prevent them from moving or falling during an earthquake. Seismic stoppers should be suitably determined by the size and weight of these heavy items; however, they have no general design standard. In this study, structural analyses and seismic tests were conducted to evaluate the performance of newly designed seismic stoppers. Structural analysis was performed on three stopper models to estimate the external load at which the yield stress of the material was not exceeded. Based on the analysis results, a seismic test of the stopper was carried out in accordance with the AC156 test method. Finally, product specifications for all three seismic stopper models were determined and their static/dynamic load performance was evaluated.

AC substation of urban transit supplies a suitable AC power on electricity vehicles. AC substation is verified electrical safety of system through pre-operation inspection on electrical installations to be supplied power from KEPCO. However, because test items and method for AC traction system are unprepared on pre-operation inspection, the general safety and performance verification of AC traction system are very insufficient. Therefore this paper analyze the test examples such as factory equipment tests, factory combined tests and railway tests for the safety and performance verification of AC traction system and present a suitable test items and test standard in domestic.

Unmanned aerial vehicles(UAVs) are increasingly used in civilian areas as well as in military areas due to the technological advancement of UAVs. In response to the increasing demand in UAVs, many studies are under way to integrate the airspace between manned aircraft and UAV. The development of flight test can secure the performance and flight characteristics of the designed aircraft. And the capability of research and development can be expanded through the accumulation of technical data. It is also essential to verify the correct performance and characteristics of development aircraft themselves. In this paper, we propose development flight test procedures and items for civilian UAVs.

The portion of embedded software in railway signaling system is increased by the advance of computer and communication technology. And the safely requirements for railway system are standardized by int'l std., such as IEC 62278 and IEC 62279. According to these circumstances for software safety problems, we are deduced the testing items for software safety test and assessment for railway signaling. Testing tools used for embedded software are surveyed to find a feasible safety assessment architecture. And the architecture of automatic test tool is proposed to test the deduced safely testing items in this paper.

This study was conducted in order to develop an aptitude test for child care teachers (ATCCT) and to analyze it in terms of both validity and reliability. The main participants in this study consisted of 710 pre-service child care teachers. The results of factor analysis identified 7 factors and 56 items which were selected from 121 items in the original scale. The seven factors were as follows; interpersonal relationship management abilities, receptiveness and responsiveness to children, creativity and personal development, the ability to form close relationships with children, the ability to supervise child safety, the sense of duty, and positive emotions. The four factors were related to social relationship. Criterion-related validity was established by using correlations between the ATCCT and the TSES (Teacher Self-efficacy Scale). The internal consistency was found to be relatively high (Cronbach's ${\alpha}$ = .94) and test-retest reliability was also established (r = .53). In addition, there were differences among pre-service child care teacher groups according to both relative levels of education and courses taught.

With the 4-MJ synthetic testing facilities completed, KERI can perform the circuit breaker testing up to 420 kV, 50 kA ratings. The short-line fault test is one of the necessary test items which are required for the circuit breaker, and in order to perform the short-line fault test KERI(Korea Electrotechnology Institute) has used the "new artificial line" which has small dimension and is easy to generate the saw-tooth wave. This paper describes the following items of the new artificial line. -Description of 4-kinds of artificial lines and determination of the circuit parameter of artificial line. -TRV characteristics of saw-tooth waves for each circuit. -KERI's artificial line.

DC substation of urban transit supplies a suitable DC power on electricity vehicles by being supplied from KEPCO. DC substation is verified electrical safety of system through pre-operation inspection on electrical installations to be supplied power from KEPCO. However, because test items and method for DC traction system are unprepared on pre-operation inspection, the general safety and performance verification of DC traction system are very insufficient. Therefore this paper analyze the overseas test examples such as factory equipment tests, factory combined tests and railway tests for the safety and performance verification of DC traction system and present a suitable test items and test standard in domestic.

Current mathematics of CSAT(College Scholastic Ability Test) faces time to prepare examination questions according to the new curriculum making this year the last. MEST(Minister of Education, Science and Technology) already decided the range of examination in 2008. However, the discuss about how to construct the questions and what form of questions should be set was not conducted enough. Mathematics items of CSAT will have to undergo changes both in 2012 and 2014. Also, reconstruction of the examination questions for the past 16 years and the exploration of the new direction are strongly required. To accord with these requirements, this study analyze Japan's college entrance exam, NCTUA(National Center Test for University Admissions) which is the most similar to our exams. And then on the basis of this, the applicable implication to set mathematics questions in 2012 and 2014 CSAT will be deducted.
