Focusing on the situation where there are not many actual users of VR / AR, this study, from the viewpoint of technology adoption and use, explores the adoption-and-use process of AR contents that can be easily accessed by using smartphones. As a result, the factors influencing the necessity of AR contents were 'enjoyment' and 'satisfaction', and other factors, such as 'innovativeness', 'the experience of using similar media', and 'the number of AR usage', did not have significant impact on the necessity of AR contents. In addition, as a result of verifying level differences in 'enjoyment', 'satisfaction' and 'necessity' according to the experience of using AR content, only the 'enjoyment' and 'satisfaction' showed that there are differences. In other words, it can be interpreted that the users in their 20s actively use AR content only when they expect to have fun and satisfaction. To sum up, this study can provide an important implication for understanding the tendency of early AR content users' perception and usage behavior.

This study looks deep into how user's individual personality and his or her media experiences affect perceived usefulness and perceived ease of use about UHDTV based on Technology Acceptance Model using survey methodology. This study also focuses on how the purchase intention of terminal equipments and the willingness to pay for UHD contents will make different choices. The result of this study shows that, whether user is an exhibitionist or not or has frequently encountered a big screen, these factors affect both the perceived usefulness and the perceived ease of use about UHDTV. When user is an exhibitionist with more experience with big screens, it was clear that user tended to choose UHDTV with higher perception of usefulness and ease of use about UHDTV. This study also implies that when supplying the next generation broadcasting service, it is needed to consider the users' perceived usefulness and ease of use about UHD as well as the individuals' media experiences and characteristics.

The role and importance of VE have been enlarged since VE application was mandatory by law in public sector in March, 2000. Public organizations have widened the technological horizon through VE competitions and applied VE technique to private investment projects. Many studies have been carried out on function analysis and VE procedure. In practice it is common that clients make a decision one-sidedly on whether or not VE proposals are selected. The VE procedure itself is not smooth. This study gives some suggestions on VE appraisal procedure and criteria at the last phase on VE process in order to smooth the progress of VE. The results of this study can be used as a tool to improve efficiency in the management of VE.
