On the basis of the development of KSLV-1, KoDSat was designed and manufactured to demonstrate the performance of KSLV-1. KoDSat is exposed to a severe vibrational environment at launch. The structural reliability of KoDSat has to be verified using vibrational test. The structural compatibility and verification of components between analysis and test can be proved using environmental vibration test. In this paper, we review the structural characteristic of thruster control unit for a space launch vehicle and design TCU housing using mathematical model. In order to verify the structural compatibility and reliability, half-sine shock, random and sing sweep vibration test was performed. Especially, sing sweep vibration test result is compared with analysis result and mathematical model is verified.

Electric motor efficient improvement from home appliance field is important to the effect reducing the energy consumption. But the electric motor design/analysis technology is still insufficient. Specially the electric motor design/analysis technology of satisfying characteristic of both the induction motor and the synchronous motor such as Line start permanent motor. Therefore the electric motor design/analysis technology is urgently demanded reliability. This paper proposes the sing1e-phase line-start permanent magnet motor to develop the motor it with be able to alternate the sing-phase induction motor it is a refrigerator compressor motor. The sing-phase induction motor is analyzed in the steady state. And we have a certification test to compare our single-phase line-start permanent magnet motor with the sing-phase induction motor. In order to improve the performance, the stator of the single-phase line-start permanent magnet motor is same as the stator of the sing-phase induction motor and changes the rotor form and has the permanent magnet. It used the Finite Element Method(FEM) which is widely used with electronic-magnetic field numerical analysis method.

In order to verify the statistical performance of the nonparametric tests used in the MARSSIM approach, all plausible contamination distribution types that can be encountered in a survey area should be investigated. As the first of such investigations, this study aims to perform the verification for normal distribution of the contamination in a survey area by simulating the collection of random samples from it through the Monte Carlo simulation. The results of the simulations conducted for a total of 81 simulation cases showed that Sign test and WRS test both exhibited an excellent statistical performance: 100% for the former and 98.8% for the latter. Therefore, in final status surveys of the MARSSIM approach, a high statistical performance can be expected in applying the nonparametric hypothesis tests to survey areas whose net contamination can be assumed to be normally distributed.

One-dimensional arrays with subscripts formed by induction variables in real programs appear quite frequently. For most famous data dependence testing methods, checking if integer-valued solutions exist for one-dimensional arrays with references created by induction variable is very difficult. The I test, which is a refined combination of the GCD and Banerjee tests, is an efficient and precise data dependence testing technique to compute if integer-valued solutions exist for one-dimensional arrays with constant bounds and single increments. In this paper, the non-continuous I test, which is an extension of the I test, is proposed to figure out whether there are integer-valued solutions for one-dimensional arrays with constant bounds and non-sing ularincrements or not. Experiments with the benchmarks that have been cited from Livermore and Vector Loop, reveal that there are definitive results for 67 pairs of one-dimensional arrays that were tested.

These experiments were conducted to learn the antibiosis of microfloral organisms in the casing soil to Mycogone perniciosa, and interactions between M. perniciosa and Agaricus bisporus. The results obtained were as follows: 1. In vitro tests, the development of M. perniciosa was suppressed from the unidentified microfloral organisms in the casing soil. All the infected sporophores of A. bisporus occurred within an area applied with spore suspension of M. perniciosa as spot treatment and no infected ones in the area around the spot treated under cropping conditions. 2. In vitro tests, although the antagonistic relationship between M. perniciosa and A. bisporus was somewhat different in varying the kind of media, A. bisporus ultimately overgrew the colony of M. perniciosa. When spore inoculation of M. perniciosa was applied on the surface of grain spawn of A. bisporus and the mid layer of casing soil under cropping conditions, no infected sporophores were produced, whereas the infected sporophores were only produced on casing soil inoculated on the surface of casing soil with spore suspension.

The purpose of this paper is to examine the effect of using songs for the acquisition of English Prosody in elementary school. For the purpose, 8 classes were chosen to teach songs for four months, and listening tests and reading test were performed for analyzing the effect. The result is as follows : (1) The result of listening test showed that the average scores of the experimental classes were higher than those of comparative classes, and it was more effective in lower grades than in upper grades. (2) In pronunciation tests, the pronunciations of experimental classes were more similar to native speaker's pronunciation that those of comparative classes in intonation, lexical stress and sentence stress. (3) Singing songs repeatedly is more important than learning many songs. It means that to give the chances to sing as many times as possible is advisable for teaching pronunciation.
