Traditionally, 3D display technologies and bio-signal measurement technologies have been studied separately. If both technologies will be integrated, however, it is projected not only to maximize the effectiveness of 3D display but also to create a new market for personalized display. The purpose of this research is to suggest SMART (i.e., Specific, Measurable, Action oriented, Reliable, and Timely), which is the criteria for developing and applying personalized 3D display technologies. This research analyzes the existing multi-view 3D display and acquisition technologies, determines the technologies suitable for integration with bio-signal measurement technologies, and identifies the types of bio-signals that could create synergy with multi-view 3D display technologies. To test and apply the suggested SMART, this research conducts case study in health care field. © 2014, Springer Science+Business Media New York. Source

The purpose of this paper is to study the differences of factors affecting banking behavior in multi-channel environment. This paper adopted multi-group structural equation modeling to compare the differences of causalities between internet and mobile banking. The result of causality in this paper generally supports the theory of technology acceptance model and the paths across the two groups are different. Certain relations in multi-channel are the same, for example the behavioral intention of internet banking and mobile banking usage are determined by perceived usefulness, trust and perceived ease of use sequentially. Alternatively, several differences exist in the external variables of beliefs. Internet banking regards self-efficiency and perceived ease of use more important. Mobile banking considers situational normality and trust more important. © 2015, Springer-Verlag France. Source

The objective of this study was to analyze the flavor patterns of commercial Korean distilled spirits using a mass spectrometry-based electronic nose and an electronic tongue. Thirteen types of domestic distilled spirits were used for analysis. The flavor patterns of the distilled spirits were clearly identified through discriminant function analysis of the raw materials. The obtained data of the electronic nose analysis showed that the flavor pattern of the distilled spirits aged in oak barrels was not significantly different from that of the general distilled spirits. According to the results of the electronic tongue, the distilled spirits made with rice had a stronger flavor than those made with foxtail millet. Compared to the sensitivity value of each taste sensor, the distilled spirits showed various intensities of sourness and umami. Therefore, an electronic nose and electronic tongue could be successfully used for quality evaluation and new product development of distilled spirits. Source
