Dental prosthesis translucency importantly contributes to aesthetic outcomes. The purpose of this study was to investigate the effect of drying time and zirconia coloring agent type on translucency. For the experiment, 90 circular specimens were fabricated for each zirconia block. Then, zirconia specimens were treated with a coloring agent for 180 seconds and dried for 0 seconds (undried), 30 seconds (intermediate dry), or 30 minutes (complete dry). Then, a specimen was placed on a black standard tile or a white standard tile, and using a standard D65 light source reflected was measured using the light removal method. A total of three repeated measurements were obtained per specimen. One-way ANOVA was used to compare and analyze the relationship between zirconia translucency and drying time. Zirconia and coloring liquid types were significantly associated with translucency (P < 0.001). Although no significant difference was observed with respect to drying time (P > 0.922), zirconia in the completely dried (30 minutes) state was more translucent.

This paper considers the historicity and aesthetical implications of in the art world of Paul Ryan(1943-2013) who designed the aestheticization of relational circuit of society by realizing the value of social transformation being inherent in video with cultural practices and suggesting the interdisciplinary method of leaning and research in the early video art history. To do this, in Chapter II, I review the first artwork presented firstly in the art gallery exhibition "TV as a Creative Medium" in 1969, in which Ryan proposed a video medium as a communication system and experimented the concept of 'feedback' in Cybernetics. And Chapter III focuses Ryan's discursive activities contributed to magazine Radical Software and artist-collective Raindance Corporation with growing interest in communication technology. At this time, Ryan regarded video medium as the tool for cybernetic expansion. Finally Chapter IV deals with the development of ecological method based on "a shared perception of environmental realities" and verifies Ryan's vision that video medium would be most effective means of social change and communication.

At present, the research of the method of 'Blank-Leaving' can be easily found in works of arts and architecture, while it can be hardly discovered in the academic research of film and television. However, as a means of expression, 'Blank-Leaving' gives a unique artistic charm to film and television works, and its development has a positive aesthetic effect to film arts. In order to go into details of the thought of 'Blank-Leaving' in movies, this paper firstly discusses the definition of 'Blank-Leaving', the history and social origin of 'Blank-Leaving' as well as its relationship with Taoism and its application in traditional Chinese painting. Secondly, this article analyzes its function and artistic expression in the film and television and the ideas sublimation it brings to people by means of combining the thought of 'Blank-Leaving' in Taoism. Finally, this work put forward the method of innovation and perfection of 'Blank-Leaving' in film and television works. This paper shows that, as a means of expression, 'Blank-Leaving' has not only realized the value of beauty, but also strengthened the public awareness of film arts.

As information communication technologies have highly advanced, a large amount of user sensitive information can be easily collected and unexpectedly distributed. For user-friendly services, a service provider requires and processes more user information. However known privacy protection models take on a passive attitude toward user information protection and often involve serious weaknesses. In reality, information exposure by unauthorised access and mistakenly disclosure occurs frequently. In this paper, we study on the applicability of anonymous authentication services for fine-grained user privacy protection. We analyze authentication schemes and classify them according to the level of privacy newly defined in this paper. In addition, we identify security requirements that a privacy protection scheme based on anonymous authentication can achieve within legal boundary.

This study was conducted on the premise of the development of cultural products using relic assets of traditional culture in a knowledge and information society led by culture and soft power. It was conducted in the context of exploring the possibility of cultural content products of Wa-Dang relics excavated from traditional architecture in the Unified Silla Period and expanding the scalability of commercialization motifs that are highly useful in jewelry design. First, the original form, material, use, size, meaning, and formative aesthetics of Wa-Dang were identified through literature and media research. Among the considered Wa-Dang, 10 types of Wa-Dang which represent the category and have values in modules and patterns were selected, and, then, circular images were extracted and modularized with a "formal simplification technique." Based on the "mathematical symmetry analysis technique," which is a method of systematizing pattern composition arrangement format. we derived a planar formative element that can be used in the development of the cultural content industry and jewelry design. In order to expand its usability in the jewelry industry in the future, it was presented as a 2D digital image. In the future, we hope more studies on the various cultural content industry utilizing the traditional culture will be carried out.
