문화 간 비교 연구를 통해 다른 문화권의 사람들은 정보의 인지과정 뿐 아니라 같은 사건에 대해서도 서로 상이한 판단을 내린다는 것을 증명해 왔다. 본 연구도 비주얼 함축 광고의 평가에 있어서 문화적 요인이 어떻게 영향을 미치는가에 대하여 미국과 한국, 두 나라의 대학생들을 비교하여 분석하였다. Study1에서는 서구와 같이 개인주의가 현저한 문화에서의 성향적(dispositional)귀인 조건과, 동양의 집단주의 문화의 특성으로 집단과 개인의 맥락에 따라서 행동을 결정하는 상황적(situational) 귀인 조건에서의 광고태도 및 브랜드에 대한 태도를 비교, 검증하였다. Study2에서는 프레이밍(자극추구/사회적 이슈)에 따라 광고주의 의도에 대한 이해의 정도가 조절되는지를 실험하였다. 위 두 가지 실험의 결과는 비주얼 함축 광고의 평가에 있어서 미국과 한국이 서로 다른 문화적 요인이 작용하고 있음이 밝혀졌다. 아울러 사회적인 이슈를 상품광고에 활용하는 데 있어서도 일부 미국의 성향적 사고의 사람들을 제외하고는 거부감이 없다는 결과를 통해 상품광고의 크리에이티브의 시야를 한층 넓힐 수 있게 되었음에 그 의의가 있다. Cross-cultural research has consistently shown that people in different cultures have different attribution systems, which often leads to different cognitive processing of information and even different judgments on the same event. This research reports the role of cultural attribution in evaluating pictorial implicature ads. Study 1 examined the attitudinal consequences of dispositional vs. situational attribution. Study 2 examined whether culture moderates the impact of advertiser`s intentions by framing attribution (sensation seeking vs. social issues). The results of the two experiments document the consequences of different cultural attributions in evaluating pictorial implicature advertisements between the US and Korea.

Fe thin films containing Si particles were prepared on metallic substrates by electrodeposition method in sulfate solutions and the content of codeposited Si particles in the films was investigated as a function of applied current density, the content of Si particels in the solution, solution pH, solution temperature and concentration of FeSO₄7H₂O in the solution. The amount of Si codeposited in the film was not dependent on the applied current density, solution pH and solution temperature, while it was dependent on the content of Si particles in the solution and the concentration of FeSO₄7H₂O in the solution. The amount of Si codeposited in the film increased with increasing content of Si particles in the solution but reached a maximum value of about 6 wt% when the content of Si particles in the solution exceeds 100 g/l. On the other hand, the content of Si codeposited in the film increased up to about 17 wt% with decreasing concentration of FeSO₄7H₂O in the solution. These results would be applied to the fabrication of very thin Fe-6.5 wt%Si sheets for electrical applications.

Alloy718 마찰용접재의 비커스 경도의 통계적 성질에 관한 연구
권혁용(HYEOK-YONG KWON),최성웅(SUNG-YOONG CHOI),이상열(SANG-YEAL LEE),공유식(YU-SIK KONG),김선진(SEON-JIN KIM) 한국해양공학회 2008 韓國海洋工學會誌 Vol.22 No.5
The objective of this paper is the investigation of the statistical properties of Vickers hardness (HV) of friction welded parts in nickel based super resisting steel, alloy 718 steel. First, we examine the statistical properties on the case of as-welded parts. Several Virkers indentations were made under same nominal conditions. This was repeated for three different applied loads, 100, 200 and 300g with a duration time, 10 second. The arithmetic mean of Vickers hardness in base metal (BM) materials is larger than that of HAZ in all applied loads. The measure of dispersion, that is, the coefficient of variation (COV) for BM and HAZ is decreased by increasing with the applied load. The distribution of Vickers hardness was not found to be symmetric type. The probability distribution of Vickers hardness was well followed Weibull distribution. The shape parameter and the scale parameter (characteristic hardness) are increased by increasing with the applied load, as both BM and HAZ.

몬테카를로 시뮬레이션에 의한 미소 비커스 경도의 Weibull 통계 해석
김선진(Seon-Jin Kim),공유식(Yu-Sik Kong),이상열(Sang-Yeal Lee) 대한기계학회 2009 大韓機械學會論文集A Vol.33 No.4
In the present study, the Weibull statistical analysis using the Monte-Carlo simulation has been performed to investigate the micro-Vickers hardness measurement reliability considering the variability. Experimental indentation test were performed with a micro-Vickers hardness tester for as-received and quenching and tempering specimens in SCM440 steels. The distribution of micro-Vickers hardness is found to be 2-parameter Weibull distribution function. The mean values and coefficients of variation (COV) for both data set are compared with results based on Weibull statistical analysis. Finally, Monte-Carlo simulation was performed in order to evaluate the effect of sample size on the micro-Vickers hardness measurement reliability. For the parent distribution with shape parameter 30.0 and scale parameter 200.0 (COV=0.040), the number of sample data required to obtain the true Weibull parameters was founded by 20. For the parent distribution with shape parameter 10.0 and scale parameter 200.0 (COV=0.1240), the number of sample data required to obtain the true Weibull parameters was founded by 30.
