通貨衝擊의 變動性이 相對價格의 變動性에 미치는 효果分析
金奉浩 건국대학교 1990 論文集 Vol.31 No.1
Korea has suffered from high inflation rate since the mid-1960's. During this terms money growth rate moved same directions. The purpose of this study is to test money shock effects on the relative price variability. A theoretical explanation of the relationship between price level variance and relative price dispersion was offered by Barro(1976) This model are constructed that individuals possessing incomplete current information and demand and supply in each market reacting to relative price as they are locally perceived. Thus, agents are confronted with the problem of determining whether locally observed price movements are caused by general inflation or by shifts in relative excess demand. The larger the variance of the money supply, the more likely are agents to attribute local price movements to general inflation rather than to relative shifts. To test relation money shock variability and relative price variability, in the first stage we estimated the money supply equation by OLS method. A measure of the variance of the money shock was also estimated. The testing of the relative price variability showed a statistically significant correlation between VPSt-i and VRt. The VPSt-i turned out to have positive coefficient which was marginally significant since VPSt-7. The result consistent with our argument saying the less uncertainty the better.

The purpose of this study is to investigate the effect of authentic leadership recognized by wrestlers on exercise immersion and performance. The selected data were derived from frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis using the SPSS Ver. 29.0 program. First, among the sub-factors of authentic leadership, balanced leadership behavior and human communication were found to affect cognitive commitment. Second, among the sub-factors of authentic leadership, self-growth, balanced leadership behavior, sincere attitude, and human communication were found to affect behavioral immersion. Third, among the sub-factors of authentic leadership, self-growth, balanced leadership behavior, and human communication were found to affect economic confidence. Fourth, among the sub-factors of authentic leadership, self-growth, balanced leadership behavior, and sincere attitude were found to affect game management ability.

30 cm 급 항공용 반사 망원경계에서 외부 환경 및 내부 진동에 의해 발생하는 주 반사경의 광학적인 성능 저하를 최소화하기 위하여 주 반사경의 광기계 설계를 수행 하였다. 플렉셔를 포함한 주 반사경의 해석을 위한 경계조건으로는 광학면의 수직과 수평 방향의 중력에 의한 변형과 온도 변화 ${\pm}1^{\circ}C$에 의한 열 변형을 고려하였다. 반사경의 기계적인 변형은 NX 5 I-DEAS를 사용하여 해석 하였다. 최적화된 경량화 반사경과 플렉셔의 중력에 의한 광학면의 형상 변형은 RMS surface error 16 nm 이하로 초기 설계 목표값을 만족하였다. 온도 변화 ${\pm}1^{\circ}C$에 의한 광학면의 형상 변형과 assembly load에 의한 광학면의 형상 변형은 매우 작은 값으로 주 반사경의 변형에 영향을 주지 않음을 확인하였다. Optimization of a 30 cm lightweight mirror was proposed with the best optical performance under various loads of gravity and thermal loads with proper boundary conditions. A pattern for a lightweight mirror was generated based on the best optical performance combined with ease of manufacturing for proper design parameters of physical properties of face sheet, back sheet, rib, and web. Evaluation of the optical performances of a telescope mirror was obtained by using the finite element analysis program, NX I-DEAS. Surface errors, individual aberration terms, such as piston, tilts, focus and other aberrations were calculated by using Zernike polynomials. The proposed telescope mirror meets well the opto-mechanical design consideration of RMS surface error less than 16 nm.

The effect of physicochemical properties of organic solvent and dispersant among organic solvent dispersant binder and plasticizer which are used as processing additives in MLCC fabrication process on the dispersion of BaTiO3 was studied. The steric and electrostatic stabilization mechanisms in dispersion of BaTiO3 in organic media were evaluated respectively. The sttability of BaTiO3 achieved bysteric stabilization was dependent on the fraction of surface coverage of dispersant adsorption on BaTiO3. The electrostatic repulsive forces of BaTiO3 particles dispersed in orgainc media was found to be appreciabley great and dependent mainly on the kinds of organic solvent used. The mechanism affecting the stability of BaTiO3 was studied by the method of rheologi-cal behaviors of BaTiO3 suspension.
