The purpose of this study was to establish the causal structural model among brand image and country image associated with consumers' purchase decision of products. The specific objectives were 1) to analyze the effects of brand image on consumers' purchase decision of products, 2) to analyze the effects of country image on consumers' purchase decision of products, 3) to analyze the effects of brand image on country image, 4) to analyze the mediating effects of country image between brand image and consumers' purchase decision of products. The conclusions of this study are as follows: First, companies must have an advantage strategy for brand image along with country image. To this end, a strategy to promote the brand image through various media is effective. Second, it is necessary to find new transformation through the establishment of brand identity at the corporate level so that consumers can have a good impression on the brand image. Third, it is important for companies to make efforts at the level of brand image and country image to provide consumers with information that can increase expectations and actual satisfaction and to build product reputation. In addition, it is necessary to embody brand images and country images into global marketing mix strategies. Fourth, if companies build a brand image that symbolizes a differentiated culture, the brand image can have a positive effect on consumer purchase decisions. Along with this, companies can further increase their positive effects by developing representative brand image contents. Fifth, this study confirmed that the higher the image level of the manufacturing country in a situation where consumers' preferences are diversifying, the more the brand image leads to consumers' purchasing decisions. Therefore, brand managers are required to build a country image suitable for the existing brand image when advertising at the time of product introduction.

The main objective of this study was to investigate the awareness and perception of young professionals in Malaysia, Indonesia, and Vietnam countries on the ASEAN Economic Community (hereafter, AEC). Data from a survey of 575 young professionals, with approximately equal distribution from each country, were collected in June and July 2015. Research findings revealed that the knowledge and understanding of the AEC among the Gen Y professionals were still marginal. Although they lack awareness, young professionals had a good impression and perception of the AEC in connection with important benefits for them individually as well as for their country. Finally, the study revealed that the Gen Y professionals showed some level of optimistic attitude that they could succeed in the AEC as they thought that they were quite well prepared, having sufficient skills to work or to do business in other ASEAN countries.

PURPOSE. The purpose of this study is to assess the accuracy of three intraoral scanners along the complete dental arch and evaluate the feasibility of the assessment methodology for further in vivo analysis. MATERIALS AND METHODS. A specific measurement pattern was fabricated and measured using a coordinate measuring machine for the assessment of control distances and angles. Afterwards, the pattern was placed and fixed in replica of an upper jaw for their subsequent scans (10 times) using 3 intraoral scanners, namely iTero Element1, Trios 3, and True Definition. 4 reference distances and 5 angles were measured and compared with the controls. Trueness and precision were assessed for each IOS: trueness, as the deviation of the measures from the control ones, while precision, as the dispersion of measurements in each reference parameter. These measurements were carried out using software for analyzing 3-dimensional data. Data analysis software was used for statistical and measurements analysis (α=.05). RESULTS. Significant differences (P<.05) were found depending on the intraoral scanner used. Best trueness values were achieved with iTero Element1 (mean from 10 ± 7 ㎛ to 91 ± 63 ㎛) while the worst values were obtained with Trios3 (mean from 42 ± 23 ㎛ to 174 ± 77 ㎛). Trueness analysis in angle measurements, as well as precision analysis, did not show conclusive results. CONCLUSION. iTero Element1 was more accurate than the current versions of Trios3 and True Definition. Importantly, the proposed methodology is considered reliable for analyzing accuracy in any dental arch length and valid for assessing both trueness and precision in an in vivo study.

PURPOSE. The purpose of this study is to present a methodology to evaluate the accuracy of intraoral scanners (IOS) used in vivo. MATERIALS AND METHODS. A specific feature-based gauge was designed, manufactured, and measured in a coordinate measuring machine (CMM), obtaining reference distances and angles. Then, 10 scans were taken by an IOS with the gauge in the patient's mouth and from the obtained stereolithography (STL) files, a total of 40 distances and 150 angles were measured and compared with the gauge's reference values. In order to provide a comparison, there were defined distance and angle groups in accordance with the increasing scanning area: from a short span area to a complete-arch scanning extension. Data was analyzed using software for statistical analysis. RESULTS. Deviations in measured distances showed that accuracy worsened as the scanning area increased: trueness varied from 0.018 ± 0.021 mm in a distance equivalent to the space spanning a four-unit bridge to 0.106 ± 0.08 mm in a space equivalent to a complete arch. Precision ranged from 0.015 ± 0.03 mm to 0.077 ± 0.073 mm in the same two areas. When analyzing angles, deviations did not show such a worsening pattern. In addition, deviations in angle measurement values were low and there were no calculated significant differences among angle groups. CONCLUSION. Currently, there is no standardized procedure to assess the accuracy of IOS in vivo, and the results show that the proposed methodology can contribute to this purpose. The deviations measured in the study show a worsening accuracy when increasing the length of the scanning area.

The purpose of this study is to examine the effects which applies teaching program that search solution to prevent global warming in middle school gifted class. This program of total 10 class was theoretical and experimental class and the students presented after collecting the synthetic data about climate-change and roleplayed what they debated to firm their country's opinion about Kyoto Protocol. Finally, students as policymaker made mock Kyoto Protocol by discussion. Impression papers and images about climate-changes was made by students in last class. In discussion of making up mock Kyoto Protocol, developed and developing nations had an argument about carbon dioxide emissions because of their economic benefits. In the course of allocating mutual $CO_2$ reduction, they needed yield and negotiation among nations. Although they mainly took passive position about $CO_2$ reduction, atmosphere that all the country make greater effort for the future global environment was formed. Like this, students had more concepts over climate change by making mock Kyoto Protocol. And they could equipped global scientific literacy and responsibility by participating in social decision making process of solving global environmental issues.

과거 연구들은 원산지(COO)효과의 존재여부에 주목하였으나, 본 연구는 사회판단이론(social judgeability theory)을 적용하여, 어떤 상황에서 원산지(COO)가 소비자의 제품평가에 영향을 미치는지를 연구하였다. 두 개의 실험결과에 의하면, 단지 어느 나라에서 자동차가 만들어졌다는 정보(COO only information)만으로는 제품에 대한 평가에 영향을 미치지 않고, 그 차를 만든 나라와 그 차를 만든 기업의 이름(product-specific information)이 제시될 때, 응답자들은 원산지 효과를 활용할 수 있는 충분한 근거(단서)를 가졌다고 느끼고, 또한 응답자들이 사회의 공통적인 판단 기준(socially shared criteria of validity)에 부합하여 판단하여야 하는 동기를 부여 받았을 때, 원산지 효과가 제품 평가에 유의한 영향을 미치는 것으로 나타났다. 특히, 각 실험 결과는 단순히 원산지 평가성향으로만 소비자 평가가 이루어지는 것이 아니라 원산지 평가성향에 영향을 미치는 정보의 제시방법이 영향을 미친다는 사실을 보여주었다. 이러한 결과는 향후 인상형성 모델의 틀 안에서 좀 더 논의되어야 할 것이다.

본 연구에서는 규범적 사회의 영향이 강한 동북아시아 문화권에서 SNS 이모티콘 소통의 특징을 찾아 전통 인문사상을 기반으로 이 특징들을 해석하고자 하였다. 국가별 주류 SNS가 상이하므로, 구체적으로 중국의 위챗(Wechat)을 중심으로 이모티콘 사용에 있어서 동기요인을 도출하고, 도출된 요인에 대해 해석을 진행하였다. 연구 진행을 위해, 문헌연구와 21명에게 인터뷰를 진행하여 38개 사용동기 항목을 도출하고, 272명에게 이모티콘 이용동기에 대한 조사를 진행하였다. 연구 결과는 다음과 같다. 첫째, 위챗의 이모티콘 사용동기로 6개의 요인들이 도출되었으며 각 요인들을 감정 표현, 심미성, 유용성, 인상관리, 재미, 소속감으로 명명하였다. 둘째, 위챗 이모티콘 사용의 동기요인들 중 규범적 사회의 특징에 부합하는 '인상관리'와 '소속감' 요인을 중심으로 유가의 인문정신인 '화(和)'와 '예(禮)'사상이 이모티콘 사용에 있어서 어떻게 발현이 되는지에 대해 해석하였다. '화(和)'는 이모티콘을 이용하여 대화방에서의 소속감을 강화하고 적극적으로 자신의 존재를 부각하여 소통 과정에 잘 어우러지고자 하는 '소속감' 요인에서 나타난다. '예(禮)'는 도덕적 윤리 규범을 강조하는 것으로, 도덕적 윤리 규범에 적합한 자신의 이미지를 형성하고 이를 통해 보다 나은 관계를 조성하고 유지하는 '인상관리' 요인에서 나타난다.
