  • This paper proposes a digital watermarking scheme to protect the ownership of the freeview 2D or 3D image such that the viewer watches the image(s) by rendering a arbitrary viewpoint image(s) with the received texture image and its depth image. In this case a viewpoint change attack essentially occurs, even if it is not malicious. In addition some malicious attacks should be considered, which is to remove the embedded watermark information. In this paper, we generate a depth variation map (DVM) to find the locations less sensitive to the viewpoint change. For each LH subband after 3-level 2DDWT for the texture image, the watermarking locations are found by referring the DVM. The method to embed a watermark bit to a pixel uses a linear quantizer whose quantization step is determined according to the energy of the subband. To extract the watermark information, all the possible candidates are first extracted from the attacked image by considering the correlation to the original watermark information. For each bit position, the final extracted bit is determined by a statistical treatment with all the candidates corresponding that position. The proposed method is experimented with various test images for the various attacks and compared to the previous methods to show that the proposed one has excellent performance.

  • To the human being, the space as the objective for fundamental thought called 'Being', and the space as the place for actual experience containing 'Life and Experience', have coexisted. Such dual characteristics owned by the space have come to the present creating various spatial viewpoints. As for the space as the objective for various thoughts and interpretations, its emphasis is nowadays being moved to the existence from such being. There is the event in the core of such change. Human's recognition for the space is originated from the observed events, which appears as an immense meaning, as it 'is accumulated as the experience. Therefore, the importance of the event in another viewpoint thinking the space is becoming bigger. This research has tried to grasp the tendency for the place-orientation by grasping the meaning owned by the event through the course that the viewpoint for such space has been changed. This research put its focus on clarifying the relationship between the place and event that are brought into relief by tracking down the transitional process of the viewpoint of space in the history of Occidental philosophy. Through this process, this research came to have a grip on the relationship in which a sense of place obviously stands out in bold relief as a result of an event, an emblem of an event, condition of an event, and as an event itself. Such four patterns are not mutually individual phenomenon, but form a discourse on modern space by traversing each other crisscross.

  • The purpose of this study is to analyze the architectural space of modern and contemporary architecture which has been changed by the aesthetic cognition on space. The intention of considering architectural space aesthetically is to convert the viewpoint of seeing space as simple physical structure into different viewpoint of regarding 'space' as 'cultural place' However this does not means to apply aesthetic theory to architectural space. The aesthetic cognition on space is one of the main subjects of the expression of art from ancient to today however the appearance of space concept as architectural aesthetics accelerated by G. Semper theory after the latter half of 19th century. On the standpoint of perpetuity in architecture the aesthetics of scientific rationalism in modernism based on the reasonable thinking regards the variety of inherent characteristic in architectural space as 'Transferential Space'. On the other hand, in regarding to architectural trend, the nature in architectural space has been considered as 'Existential Space' starting from the conscious construction of environments to help human existence in the existentialism. The Conclusion logic of follows as belows; first, the concept of space structure in architecture has been exchanged from Enclosed Space to Topological Space. Second, the concept of architectural space has been changed and developed to the Deterministic, Profound, Dissipative, and Recognizable Space according to the change of expression in architecture.

  • The co-operated residential form of the apartment has been with us for 30 years. The apartment is becoming the most popular form of residence, although there is still a few aspects of the apartment that need to be Improved. After the institution of the unrestrained house value in 1989 that started in Seoul, the main viewpoint of the suppliers the uniform characteristic idea has been adjusted to the various ideas and the viewpoint of the consumer. This has resulted in the prismatic composition of buildings, more stories, upgrading the quality of the design and a preference for wider space of the residence. In this study: (1) theplane surface of interior space and the design quality of the apartment from tile beginning of the 60s are considered. (2) The attribute of the apartment is grasped through analysis of the current (2002-2003) apartment within the country according to the various areas. The prediction of the future residential environment change is analyzed and as a consequence, the modification of the interior space is forecast and suggests the design trends of the apartment. I hope that this, investigation is helpful as it attempts to produce high quality residential space that reflects the harmony of technological development of the apartment and sentiment and emotion of the human being.

  • The purpose of this study is to investigate fashion advertisements portraying ambiguous sex phenomena, including homosexuality codes and to analyze the meaning of these advertisements in order to develop effective fashion advertisements strategies. The method of this study was to observe the readings about ambiguous sex theory, including homosexuality, and analyze fashion advertisements that express this through the Internet and fashion journals. The ambiguous sex expression seen in fashion advertisements meet various consumers' needs which is what the latest advertisement market requires, and offer competitive brand image by fresh appeal. In the background, there are various complex factors like the change of contemporary spirit, and designers' tastes and values about homosexuality. The kinds of ambiguous sex expression techniques portrayed in fashion advertisements can be divided as the ambiguity of physical codes and the ambiguity of sex role identity. These advertisements do play a role as a public campaign for a change in society from the sociocultural point of view. And, from the economical viewpoint, they approach the consumer as a fresh marketing strategy. From the esthetic viewpoint, they express new esthetic sense named “edge” And seen from the designers' viewpoints, they express designers' private sexual identities.

  • In this paper, Blockchain is mentioned as the next-generation core IT technology. As an immature technology, there are not many practical use cases, but it is expected to be widely applied in various industries such as cryptocurrency, finance, public, etc. to increase efficiency and enable new services that did not exist in the past. Nevertheless, the generalization of blockchain technology is still difficult. In particular, from the viewpoint of personal information protection, GDPR of Europe, etc., is becoming stronger. Considering that the core of the blockchain is the change of information sharing and processing method, it is very important how the blockchain can affect, especially from the viewpoint of privacy, and how the Privacy Act can be applied to the blockchain. However, the discussion on this part also seems to be insufficient. Therefore, in this paper, blockchain By analyzing the implications and implications of technologies and services using them from the perspective of the Privacy Act, we will discuss how the blockchain will be used to prevent leakage of privacy.
