This study purposed to interpret subjectivity, which centers on the concept of virtuality embedded in the process of virtualizing contextual awareness and mixing the boundary between realities and virtual realities for renewing the feeling of time and space represented by augmented realities in daily spaces, from the viewpoint of traditional media. By explaining how the reflection of reality is exposed focusing on immediacy and hypermediacy from the viewpoint of media remediation, we found that, different from conventional media, augmented reality enables the screen to function as a part of subject and play a role and, by doing so, converts it to the complete subject of digital media comprehending observers and operators.

Recently, the public design plays a role in improving the residents' quality of life and activating the local economy as an axis of the regional development. However, during the development process led by the local government, the public space has been changed to a place where only the function is emphasized without considering the local history, culture, and life. Since the opinions of the regional residents are not reflected, the public place lacks public benefits and has difficulties in continuous improvement and development. Here, we studied on the participation of residents in public design. Firstly, we discussed public design that residents can participate voluntarily and actively as users, managers, and beneficiaries. Secondly, it is necessary for the residents, who are not experts in the public design, to have easily understandable and well tractable communication media which facilitate communications with a group of the design experts and the public service personnel. We explained the types and specialities of the communication media. Thirdly, it is necessary for the residents to contribute much to the local development by active participation in the sustainable and consistent public design through using the easily accessible communication media.

As various portable digital devices are developed, the space of the TV audience is expanding. We propose a structure of broadcasting control in VOD service in which viewers can resume the viewing of digital broadcasting contents in different devices after they have stopped the viewing to move to another place. Then we design a session and resource management system of VOD for this control. In particular, we design the session management of each consumer and simulate the seamless VOD connection model.

In many machines handling lightweight and flexible media, such as magnetic tape drives, xerographic copiers and sewing machines, the media must transit an open space. It is important to predict the static and dynamic behavior of the sheets with a high degree of reliability. The nonlinear theory of the dynamic elastica has often been used to a nonlinear dynamic deflection model. In this paper, the governing equation is derived and simulated by the finite difference method. The parametric cubic curve is applied for defining the guide shape. The dynamic contact conditions suggested by Klarbring is used to predict the direction of the flexible media according to the initial velocity and the friction coefficient. The analysis is also compared to the conventional model, showing that after contacting a $45^{\circ}$ wall, the directions of flexible media of two models are different.

This study will establish the transformal characteristics of architectural visual information by investigating: how contemporary architects perceive and process multifaceted architectural information via the expression media since 1970s. The purposes and results of this study are summarized as follows: This study established the contemporary transformal characteristics by comparing the expression methods of traditional architects with the transformal characteristics of visual information derived from the contemporary architectural expression media. In a pluralistic information society, the expression methods of the past, which recognize space as a stationary, unidimensional visual point on a drawing surface, is now changing to the mixed, multidimensional expression methods that connect various visual points on a limited drawing surface. Furthermore, the rapid advancement of digital media is changing, from a method which simply arranges visual information, to a flexible visual tool which can process architecture sequentially and simultaneously. As the communication structure of architecture is moving toward an individual-centered two-way communication type, the information delivery method is used to visualize conceptual, inferential information, rather than visualizing realistic information which simply records facts. In the past, multidimensional, non-linear forms could not be processed by the conventional design processes and sketch work, but now they can be expressed via digital media.

Owing to the difficulties associated with conducting millimeter-wave (mmWave) field measurements, especially in high-speed train (HST) environments, most propagation channels for mmWave HST have been studied using methods based on simulation rather than measurement. In this study, considering a linear cell layout in which base stations are installed along a railway, measurements were performed at 28 GHz with a speed up to 170 km/h in two prevalent HST scenarios: viaduct and tunnel scenarios. By observing the channel impulse responses, we could identify single- and double-bounced multipath components (MPCs) caused by railway static structures such as overhead line equipment. These MPCs affect the delay spread and Doppler characteristics significantly. Moreover, we observed distinct path loss behaviors for the two scenarios, although both are considered line-of-sight (LoS) scenarios. In the tunnel scenario, the path loss exponent (PLE) is 1.3 owing to the waveguide effect, which indicates that the path loss is almost constant with respect to distance. However, the LoS PLE in the viaduct scenario is 2.46, which is slightly higher than the free-space loss.

In recent years, large-scale and high-density use of LED on facades has exposed some disadvantages, such as light pollution, high energy consumption, unsustainability, and poor interactivity. Because of the development of smartphones and augmented reality (AR), AR has emerged as a new technology available to users to interact with the media façade. As an augmented reality app for public space, the AR map app can superimpose virtual images on the surface of a building to form an AR media façade, which can be applied in the fields of navigation, advertising, interactive public art, smart retail, etc. This study establishes the variables influencing usage intention and the consequent outcomes of Huawei AR map app and uses the technology acceptance model (TAM) to discuss their relationship. Results show that consumer innovativeness, information quality, and design quality have a strong influence on perceived ease of use. Information quality has a positive impact on perceived usefulness, but design quality has a weak influence. Also, the design quality of Huawei AR map app and consumer innovativeness have a higher effect on perceived enjoyment than information quality. Users' usage attitude and perceived usefulness when using Huawei AR map app are key factors determining their usage intention. This study inspires city planners, architects, developers, and designers of AR apps that augmented reality can partly replace media façade, and that investment in augmented reality will achieve significant sustainable economic and social benefits.
