The purpose of this study is to analyze consumers' perceived risk which is shown in the process of purchase phase and consumption phase for the counterfeits of fashion luxury brands and to analyze the interrelationship of each type of perceived risk. The research method of the study used a qualitative approach. 6 informants were selected and then an in-depth interview was held with them. Through this process the data on the perceived risk for counterfeits were collected and analyzed. The results of the study are as follows; The perceived level of psychological risk including counterfeits exposure was extremely high; besides, economic risk and performance risk were also perceived. On the contrary, the perceived level of social risk and fashionability loss were relatively low. The risk perception for counterfeits appeared not only on the purchase phase but also on the consumption phase, and when perceived risk existed on the consumption phase, it had an influence on the level of perceived risk on the next purchase phase. However the psychological risk was continuously perceived on both purchase and consumption phase, even if it did not exist on the consumption phase. Psychological risk, economic risk and performance risk were not independent but interdependent. Moreover, the entire level of perceived risk could be controlled by reducing the level of other perceived risks when a certain type of risk was highly perceived.

The recent development of the HD (High Definition) and UHD (Ultra High Definition) technology allowed the growth of 3D contents market. Yet the majority of the 3D contents in the market are strictly for 6.5 cm inter-ocular distance, causing various visual discomforts for the viewers who have different inter-ocular distance. Moreover, because the 3D contents are created for a fixed viewing distance, the change of the viewing distances when watching 3D contents can also cause visual conflicts. To solve this problem, we devised techniques that consider the environmental information of the viewer watching 3D contents. By analyzing the relationship between viewing distance, inter-ocular distance, and perceived depth, we created an adaptive content viewing system that reflects the viewer's environment to minimize any conflicts in watching 3D contents. From our experiments, we found that the performance of our adaptive content viewing system was reasonable.

Integral imaging is a three-dimensional display method which has full parallax and continuous viewpoints. However, we found an error between the depth expressed by integral imaging and the depth perceived by the observer through binocular disparity. We analyze the depth perception errors of the threedimensional image constructed by integral imaging.

Purpose The purpose of this study is to identify the utility and sacrifice factors of paid membership in domestic e-commerce based on the value-based acceptance model, and to determine its impact on perceived value and intention to continue using e-commerce. Design/methodology/approach This study confirmed the perceived benefits and sacrifice factors of e-commerce paid membership through in-depth interviews, and verified the research model through an online survey. Findings The study identifies seven perceived benefit factors(differentiation, enjoyment, sharing, point benefit, discount benefit, contents benefit, and delivery benefit) and three perceived sacrifice factors(fee, opportunity loss, complexity). Structural model verification reveals that discount benefit, delivery benefit, and opportunity loss significantly impact the perceived value in Coupang Rocket Wow, while discount benefit, point benefit, and fee significantly influence the perceived value in Naver Plus membership. The perceived value of both memberships positively influences the intention to continue using the respective e-commerce platforms. A comparison highlights a significant difference in the impact of opportunity loss on perceived value between Coupang Rocket Wow and Naver Plus memberships.

In the field of dance creation, the use of film and television skills, cyberspace, action sets, computer graphics and other technology and media technology have made the creative environment for dance art that it rapidly improves and presents a new situation. Especially in the dance creation part, VR technology can show many possibilities and can be used as a tool to fully satisfy the choreographer's intention and imagination. Therefore, this study analyzes the acceptance model of virtual reality technology in dance creative education, and we will examine the effect of social influence, shared trust, innovation, interest, and self-efficacy on perceived usefulness and perceived ease. Second, we will examine the effect of perceived usefulness and perceived ease on intention to use. The study is targeted at ordinary dance creators who currently reside in Hebei Province, China. The survey was conducted for approximately 30 days from March 16th to April 17th. The total number of valid samples collected was 377. The results of the identification of the hypotheses between variables based on the questionnaire data are as follows: Firstly, social influence, shared trust, innovation, interest, and self-efficacy have a positive impact on perceived usefulness, perceived ease. Secondly, perceived usefulness, perceived ease has a positive effect on the intention to use. In view of the above research results, the theoretical significance and limitations of this research and the future research directions are discussed in depth.

Purpose The purpose of this study is to understand the factors that influence the purchasing behavior of NFT collectibles consumers, using the value-based acceptance model (VAM). As the use of NFTs is predicted to become more widespread in the near future, it is important to explore how these consumers make purchasing decisions. Design/methodology/approach This study employed text analysis and in-depth interviews to identify the factors of benefits and sacrifices perceived by consumers. Based on the results of the exploratory study, a research model and hypotheses were established. To test the hypotheses, an online survey was conducted, and the data was analyzed using a structural equation model. Findings The major findings of this study showed that perceived benefit factors had a significant positive impact on consumers' perceived value of NFT collectibles, whereas perceived sacrifice factors did not have a significant effect on perceived value. Also, when consumers' social needs were met, their perceived value was highest. Lastly, the effect of perceived value on purchase intention was not affected by the level of psychological ownership.

Pulfrich effect implies the possibility that motion information is processed by the system that processes depth information, and this possibility by supported by various neurophysiological studies. Although Pulfrich effect is processed by the system that processes binocular disparity, the representative depth information, there has not been a psychophysical research to determine the characteristics of the interaction between Pulfrich effect and binorular disparity using a stimulus containing the two information sources. Present research examined the characteristics of the interacation between Pulfrich effect and binocular disparity by nenuring the depth and rotation direction of a rotating cylinder comprised of random dots under two different conditions: 1) consistent rendition where the Pulfrich effect and binocular disparity depth the depth and rotation direction of the cylinder in a consistent manner 2) inconsistent rendition where they did not. , The perceived depth of the cylinder in the consistent condition was larger than that in disparity/Pulfrich effect only condition. Interestingly, the perceived rotation direction of the cylinder in the inconsistent condition was modulated by the relative strength of the disparity and the Pulfrich effect. These results imply that binocular disparity and Pulfrich effect are processed by a common neurophysiological methanism.

Social entrepreneurship is increasingly gaining interest in developing countries for the great benefits of society. In Vietnam, the concept of social entrepreneurship is still quite new. Entrepreneurial intention is regarded as a useful and practial approach for understanding actual entrepreneurial behavior. The purpose of this paper is to develop an integrated model based on planned behavior to examine the direct and indirect effect of perceived access to finance on social entrepreneurial intention. The confirm factor analysis to study the latent constructs underlying determinants of planned behavioral theory, perceived access to finance and social entrepreneurial intention. Then, it applies the technique of structural equation modeling to explore relationships among latent constructs. There is no direct relationship between perceived access to finance and social entrepreneurial intention. Perceived access to finance only indirectly increases entrepreneurial intention through attitude towards behavior and perceived behavioral. This study focuses on the perceptual factor of financial access that affects entrepreneurial intentions. The study does not cover other in-depth issues of social entrepreneurship such as decision making, leadership, personality traits, social capital, and human capital. To establish an environment with a strong social entrepreneurial intention, a focus on developing perceived access to finance is an extremely important factor. This study also suggests that attitude towards behavior and perceived behavioral have a strong impact to social entrepreneurship.
