The purpose of this study is to find out the effects of reconstructing unit 'Seasonal Change' using step-by-step questioning for concepts changes to adjusting misconceptions of elementary school students. Most students have pre-conceptions at describing seasonal changes based on their experiences. Therefore, in newly developed unit, we reconstructed unit to include core teaching and learning contents by finding out common pre-conceptions of students and specifying purpose of teaching at misconceptions found in pre-conceptions as 'constituent of class for conceptual change'. After the scientific concept test, the result of 24 students in experimental group is statistically significant. Also, according to the result of qualitative analysis, the number of activated conceptional resources and degree of specificity in explaining seasonal changes are higher than that of control group.

본 논문은 시장개설 초기 4개월간의 주가지수 선물수익률과 기초자산인 현물(KOSPI 200) 수익률간의 선도-지연효과를 두 개의 모형을 이용하여 실증검증하였다. 첫 번째 모형은 설명 변수로 선물수익률의 시차변수를 사용하고 종속변수로 현물수익률을 사용했다. 두 번째 모형은 설명변수로 선물수익률의 시차변수를 사용하는 것은 첫 번째 모형과 같으나 종속변수로 ARMA모형에서 구한 현물수익률의 오차항(return innovations)을 사용하였다. 또, 여러 시장조건에서 현물수익률과 선물수익률사이의 선도-지연효과가 특정한 양상을 보이는가를 분석하였다. 좋은 정보와 나쁜 정보, 거래량이 많은 경우와 적은 경우, 변동성이 높은 경우와 낮은 경우로 나누어서 선도-지연효과를 살펴보았다. 실증검증의 결과 KOSPI 200 현물수익률은 ARMA(2,3) 모형이 적합하며 선물이 현물을 10분 이내로 선도한다. 하지만 그 관계는 일방적인 것이 아니어서 15분후에는 현물이 선물을 선도하는 피드백(feed-back) 현상이 나타났다. 좋은 정보(good news)에서는 선물이 현물을 5분정도 선도하고 나쁜 정보(bad news)하에서는 선물 선도현상이 약해진다. 보통 정보(morderate news)하에서는 현물이 선물을 10분내로 선도한다. 거래량이 많은 경우와 변동성이 높은 경우에는 선물이 현물을 선도하는 것이 뚜렷하나 거래량이 적은 경우와 변동성이 낮은 경우에는 선물과 현물간에는 특정한 선도-지연현상이 나타나지 않는다.

The magneto-optical Kerr effect due to the (Fe,Co)/(Pd,Pt,Cu,Ag) multilayer film is calculated considering of multiple reflection effect, and the calculated Kerr spectrum is compared to the reported experimental value. In case of Co/Pd, the reliance of composition and the variable tendency of magneto-optical Kerr rotation angle for Co thickness fully coresponds to experimantal and theoretical value. The theoretical Kerr spectrum of Fe/Cu and Fe/Ag multilayer films show the peaks near the Cu and Ag optical ansorption band in accordance with the experiment. But in case of Co/Pt, the increase tendency of Kerr rofation with decreasing wavelength reported by experiments could not be explained by the optical multiple interference. This difference of theoretical and experimental Kerr spectrum of Co/Pt film might be related with the change of electronic structure of Co and/or Pt from their bulk state.

The liquid chromatographic retention behavior of structural isomers of phenols was investigated by a change of the mobile phase properties. The retention behavior of structural isomer of phenols in reversed phase liquid chromatography was affected by eluent electrolyte added. It can be seen that this behavior is illustrated by a mechanism of Langmuir isotherm and ion exchange between phenolate and the reversed phase coated with ions. The retention behavior was represented as two different areas according to the concentration of the electrolytes. These areas can be explained as counter ion and co-ion effect, respectively. The maximum retention values were dependent not upon the kinds of organic modifier but upon the kinds of electrolyte.

데이터베이스 마케팅 전략을 수립하고 집행함에 있어서 고객에게 접근하기 위한 촉진 매체로써 직접우편(Direct Mail)과 텔레 마케팅 등의 직접반응매체를 주요 수단으로 하는 경우 이를 다이렉트 마케팅이라고 한다. 다른 마케팅 전략들과 마찬가지로 다이렉트 마케팅에서도 마케팅 자원이 효과적으로 사용될 수 있도록 고객 데이터베이스를 세분화하는 작업을 수행한다. 리스펀스 모델링(Response Modeling)은 다이렉트 마케팅분야에서 고객리스트를 세분화하고 각 세그멘트별로 고객의 반응(구매행위)을 예측하는 기법을 말하며 RFM(Recency, Frequency, Monetary), 로지스틱, 신경망은 리스펀스 모델링을 위해서 가장 널리 사용되고 있는 기법이다. 과거에 이들 방법은 고객 데이터베이스 전체에 단독 모델로 적용되어 왔으나 이러한 단독 모델을 고객 데이터베이스에 적용하는 것이 정당화 되려면 고객들이 동일한 방식으로 반응한다는 전제가 필요하다. 그러나 일반적으로 고객의 반응방식에는 상당한 이질성이 존재한다. 예컨대 직업, 나이, 소득, 성별 등이 같다고 해서 같은 구매패턴을 보이지는 않는다는 것이다. 즉 고객A의 구매행위는 회귀선에 의해서 잘 설명되는 반면에 고객B는 신경망이나 RFM으로 잘 설명될 수 있는 경우가 존재하는 것이다. 이러한 구매행위의 이질성을 반영하기 위해서 최근에는 두개 이상의 방법을 결합하여 사용하는 결합 리스펀스 모델링 방법도 시도 되어 왔다. 그러나 결합 리스펀스 모델링에 관한 기존 연구들은 상관관계가 낮은 모델들을 결합함으로써 세분화의 효과를 단독 모델을 사용할 때 보다 개선할 수 있다고는 하였으나 구체적으로 어떤 모델들이 서로 낮은 상관관계를 갖는지는 보여주지 못하였다. 본 논문에서는 RFM 방법을 모델 내에서 사용하는 변수와 이를 이용한 모델링 방법상의 차이로 인하여 다른 두 방법(로지스틱, 신경망)과 매우 낮은 상관관계를 갖는 방법으로 제시하고 RFM과 다른 두 방법간의 낮은 상관관계를 이용하여 결합하는 경우 모델의 예측효과를 상당히 개선할 수 있음을 사례분석을 통해서 보이고자 한다.

This paper develops a simple model to explain the reasons why foreign acquirers pay significantly higher premiums for U.S. target firms than do U.S. buyers. We also provide empirical work on the valuation effect of foreign takeovers and the determinants of the wealth gains of U.S. target shareholders involved in foreign takeovers. The results indicate that target wealth gains are significantly higher in foreign takeovers than in domestic takeovers, after controlling for the wealth effects of payment method, acquisition type, tax status, size and time period of bids. This confirms the valuation effect of foreign takeovers. Furthermore, the results of cross-sectional regression analysis show that the variation in U.S. target wealth gains is explained by extra tax benefits stemming from double tax deductions for acquisition-related interest expenses incurred by foreign acquirers. These findings imply that differential taxation across tax jurisdictions is the main source of the valuation effect of foreign takeovers. In addition, we find that there exists a valuation effect of the nationality of the foreign acquirers. Japanese companies pay significantly higher premiums than do non-Japanese acquirers. The finding also indicates that competition among bidders increases the abnormal returns to U.S. target shareholders in foreign takeovers.
