This research focuses on the theory of Zhi-jue(知覺) by Kim Chang-Hyup(金昌協) through comparison between Kim Chang-Hyup's and Zhu Xi(朱熹)'s. In the point of supervision, Zhu Xi considered that Zhi-jue is one of the conditions caused by supervision, one the other hand, it is the action that make possible supervision. Kim Chang-Hyup emphasize the concept of Zhi-jue itself, he considered that Zhi-jue is the action that make possible supervision, and separate Zhi-jue from Xing(性) or Qing(情). In this process, Zhi-jue became the subject itself about supervision, so the mix about relation between Zhi-jue and supervision is solved. But there is a problem about gap between Zhi-jue and the nature from separate between Zhi-jue and Xing. Kim Chang-Hyup intend to separate Zhi-jue and Qing as subject and object, so he considered that Xing is not a reason of Zhi-jue, but rules. It's not a answer about what is the reason of Zhi-jue. Yet Zhu Xi also considered that Xing is the rules of Zhu-jue, only in the case that Zhi-jue means the resulf of supervision, Zhi-jue is considered as the effect of Zhi(智). So the relation problem about Zhi-jue as a subject and the nature is brought up by Joseon scholar who attempted to arrange the concepts of neo-confucianism. Eventually, in case of the relation about Zhi-jue and Xing, King Chang-Hyup and Zhu Xi has a common point, only in case of the relation about Zhi-jue and supervision, Definding Zhi-jue as the subject of supervision is the character of Kim Chang-Hyup's theory of Zhi-jue.

This study is to investigate the effects of personal characteristics and perceived interactivity on acceptance of mobile health information service by applying Technology Acceptance Model (TAM). Also it examine whether the perceived interactivity, which is a key variable in the previous research studying the intention of PC-based health information service, works on the mobile environment equally. As a result of the analysis, the relationship between the health hypochondria of personal characteristics and perceived interactivity is negative, and the health concern and perceived interactivity is positive. Also, personal characteristics influence perceived usefulness and perceived ease of use of mobile health information service through perceived interactivity. Therefore, the perceived interactivity in the health information service of web and mobile environment is an important variable to mediate or directly affect other variables.

Human perception is an outcome of the influence of various factors rather than objective reflection of external environment. Among the factors, action-specific perception is a phenomenon where perception changes in terms of one's ability to act on the environment. Previous research reported contradictory results regarding whether action-specific perception occurs during performance or after performance due to memory distortion or knowledge about performance results. In this research, we conducted three experiments to determine when action-specific perception occurs. Participants threw darts at different distances and reported perceived size of targets in each trial. The results showed that, in Experiments 1 and 2, participants perceived targets larger when they hit than missed the targets, and the effect was greater when the targets were not visible after each throw. However, because participants had knowledge about the results of their throws, there could have been bias in participants' responses. In Experiment 3, where this possibility was excluded, we also obtained action-specific perception, and therefore concluded that action-specific perception occurs during but not after task performance.

Three experiments compared two hypotheses on visual selection; perceptual load hypothesis and dilution hypothesis. The perceptual load hypothesis predicts that perceptual load of task-relevant processing determines the level of task-irrelevant processing whereas the dilution hypothesis predicts that competition for limited-capacity attentional resource, not perceptual load, determines the locus of selection. To compare the two hypotheses, we investigated the influence of perceptual load in visual search on response interference by a distractor. Experiment 1 and 2 manipulated perceptual load by the set size of a search array and the colors of a target and non-targets, respectively. As a result, distractor interference decreased with a set size regardless of perceptual load. In order to further test the set size effect, Experiment 3 manipulated the perceptual categories of non-targets and a distractor. The results showed that distractor interference decreased only when non-targets belonged to the same category as a distractor. Overall, the current findings support the dilution hypothesis, but not the perceptual load hypothesis, and provide the evidence that visual selection is constrained by capacity-limited, category-specific attentional resources.

With the recent revitalization of the shared economy, bike-sharing services are gaining huge popularity in the bicycle sector. Bike-sharing services are characterized by reducing environmental pollution and borrowing bicycles at low prices. This study investigated the mechanisms for the formation of customer's continuance intention toward bike-sharing services. The theoretical framework clarified the role of perceived value and trust in enhancing customer's continuance intention. Perceived usefulness, perceived ease of use and perceived enjoyment are considered as the vital factors of enhancing perceived value and trust in a service provider. The research model was validated by data from 217 bike-sharing users in China. Both perceived value and trust in a service provider had a significant impact on user's continuance intention. However, the analysis results showed that perceived usefulness does not have a significant impact on both perceived value and trust in a service provider. Perceived ease of use and perceived enjoyment played a significant role in enhancing both perceived value and trust in a service provider. Our results are expected to provide academic and practical implications for bike-sharing services.

This study explores the factors which affect user acceptance for Robo Taxi, an electricity-based Autonomous Vehicles based on a Value based Adoption Model. The three main factors of benefit (usefulness and enjoyment), sacrifice (technicality and perceived fee level), and user experience about mobility services such as car sharing, taxi, and autonomous vehicles, were finally selected as independent variables as a influential factors on perceived values and adoption intention of Robo taxi. The study found that usefulness, enjoyment, and perceived fee had a significant effects on adoption intention, and some user experiences had a significant effect on benefit factors. This study has important implications for incorporating the Value-based Adoption Model results into the service design for the activation of Robo taxi, and furthermore, they can provide a theoretical basis for effective use of the research findings.

The wearables market has fast grown, demanding a more consumer-centric academic attention. The current research explores the moderations of consumer individual characteristics (i.e., age, need for cognition, involvement) in the dynamics of perceived psychological benefits of wearables adoption (i.e., perceived usefulness, perceived ease of use) towards perceived product quality. the results indicate a strong positive influence of both the perceived usefulness and ease of use on perceived quality. however, the predicted moderations of age, need for congitiion, and involvement were partially supported.
