The potential usefulness of Hall's concept of high- versus low-context cultures to international marketing has been discussed widely. However, implications of this concept in marketing have largely been discussed descriptively and little attempt has been made to empirically compare various cultures in a real setting. In this article the authors report the findings from a cross-cultural study that attempts to show whether Hall's description of the characteristics of high- and low-context cultures

Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a proinflammatory cytokine that has a central action to reduce food intake and body weight. Consistent with this, GM-CSF knockout mice are more obese and hyperphagic than wild-type mice. However, in lung, GM-CSF is an important determinant of macrophage infiltration. Consequently, we sought to determine if GM-CSF might contribute to adipose tissue macrophage accumulation, insulin resistance, and low-grade inflammation that occurs when

Histone deacetylase (HDAC) has been highlighted as one of key players in tumorigenesis and angio-genesis. Recently, several derivatives of psam-maplin (Psams) from a marine sponge have been known to inhibit the HDAC activity, but the molecular mechanism for the inhibition has not fully un-derstood. Here, we explored the mode of action of Psams for the inhibition of HDAC activity in the molecular and cellular level. Among the derivatives, psammaplin A (Psam A) showed the potent inhibitory activit

We present a feature-based method to classify salient points as belonging to objects in the face or background classes. We use SURF local descriptors (speeded up robust features) to generate feature vectors and use SVMs (support vector machines) as classifiers. Our system consists of a two-layer hierarchy of SVMs classifiers. On the first layer, a single classifier checks whether feature vectors are from face images or not. On the second layer, component labeling is operated using each component

These experiments provide compelling evidence for a previously unknown relationship between the status of adipose tissue vasculature and the regulation of food intake.

Structural cracks are a vital feature in evaluating the health of aging structures. Inspectors regularly monitor structures' health using visual information because early detection of cracks on highly trafficked structures is critical for maintaining the public's safety. In this work, a framework for detecting cracks along with their locations is proposed. Image data provided by an unmanned aerial vehicle (UAV) is stitched using image processing techniques to overcome limitations in the resoluti

Unlike past findings on cross-cultural advertising, culture seems to have little effect on visual forms in ads. In study 1, we tested whether the culture-congruent visual forms would still be prevalent, in spite of all the recent cultural convergence between Eastern and Western cultures. Interestingly, content analyses of visuals in 632 advertisements in a wide range of magazines from Korea (high context) and US (low context) revealed that ads with direct visual forms were more prevalent in both

가격경쟁과 할인경쟁이 치열한 시장에서 가격할인은 매출증대를 위한 중요한 판매촉진 수단이자 소비자의 구매의사결정요소이다. 본 연구는 소비자가 과거 구매경험을 통해 습득한 정보를 바탕으로 할인에 대한 준거점을 형성하고 이를 기준으로 할인의 매력도를 평가한다는 것을 통해 ‘준거할인(Reference Discount)’ 이라는 개념을 최초로 도입, 그 존재를 검증하였다. 또한 소비자들이 할인의 매력도를 평가하는데 있어 준거할인과 실제할인간의 차이를 인지하지 못하는 수용구간(Latitude of Acceptance)이 존재하는지, 만약 존재한다면 브랜드 애호도나 할인민감도와 같은 고객의 특성이 수용구간의 폭에 어떤 영향을 미치는지 알아보았다. 연구 결과 소비자들은 과거 구매경험을 통해 축적된 정보를 바탕으로 준거할인을 형성하고 이를 기준으로 할인 규모의 상대적 매력도를 평가하는 것으로 나타나 가격의 경우(준거가격)와 마찬가지로 할인에 대한 심리적 준거점도 존재함이 밝혀졌다. 그리고 준거할인
