Based on the relationship between urban public space, urban lighting and the sense of place, this paper aims to analyze the lighting environment types with the sense of place and their characteristics. First, with the theory study as the research foundation, it extracts six spatial factors of public space lighting design and then analyzes 12 relevant cases on the basis. Finally, it divides the 12 cases into four types, Basic types, Storytelling, Interactive and Multi-Media and analyzes the core design factor and characteristics of various types. The results show that: first, functionality, sustainability and aesthetics are the basic factors to realize the urban public space lighting places. Second, the six cases of "Storytelling" show that the theme of specific areas, namely the exploration of "story" is conducive for lighting design to form clear and definite environment recognition. Third, for "Interactive" and "Multi-Media", the intervention of new media technology and new lighting way has made the wide expansion of urban lighting design connotation and extension. The research results show that strengthening the urban location performance by the lighting design could improve the city image, which provides the basis for the development of urban public space lighting design.

In the 1960s, light art using neon or fluorescent lamp, etc and 'light and space art' appeared with kinetic art. Light art that is an extension of kinetic art tends to be digitalized art and focus on movement, while light and space art emphasizes psychological side and focuses more on phenomenal experience than movement itself. Light art generally tends to offer visual play, but light and space art offers not only visual play but also deep impression on audience's mind. In this paper, LED control method using sound and how color change influences people's mind are studied based on my works try to supplement shortcoming of light art. The main goal of my work is to make more effective and empathic interaction between audience and light in order to avoid cold and mechanical impressions that light art has. Based on its contents, this study seeks method to stimulate people's emotion, and suggests applying mentality on the color and sound interaction together to media art. In conclusion, it is believed that new model of media art is suggested through this study.

The purpose of this study is to reassert the important role of sound design in creating narrative space in films. The main focus is on re-interpreting Chion's sound space composition as a narrative structure. The sound design process has been analyzed to find that the physical properties of sound are purposely manipulated to create the layers of sound to be perceived by the audience in the same way as human perception and cognition of the actual reality work, eventually to create the cinematic reality. The hierarchy of the layers is determined by the importance of the narrative information contained in each sound, with the higher layers being appropriate to convey the information of the narrative, and the lower layers being efficient to deliver the emotion to the audience. With this idea, each of the Chion's space composition is explained as a distinctive area in telling a story with the separate narrative role from the others.

This study is an experiment on the use of RDW(Redirected Walking) technology, which helps users to hardly feel the difference of user movement in the limited physical space and the extended virtual space when the user moves while wearing the HMD in the real world. The RDW function installed in 3D space realization software such as Unity3D is used to induce the user's redirection by slightly distorting the virtual space according to the user's point of view. However, if the RDW distortion rate is used excessively, dissonance is highly likely to occur. In particular, it is easy to make errors that cause cybersickness of users. It is important to obtain the RDW data value in the virtual environment so that the user does not feel fatigue and cybersickness even after wearing the HMD for a long time. In this experiment, it was tested whether the user's RDW was safely implemented, and item and obstacle arrangement data were obtained through this experiment. The RDW data obtained as a result of the experiment were used for item placement and obstacle placement in the virtual space.

Currently, Korea is achieving cultural, economic, and social growth as a member of the international community along with its social growth. In the 2000s, local communities and local governments made multidimensional efforts with historical and cultural interests. And as part of that, historical museums were built or expanded to increase the quantity in anticipation of citizens' satisfaction and attracting visitors. However, the qualitative effect of the exhibition space is not achieved. Therefore, in this study, the analysis according to the complex system theory on the interrelationship between exhibition planning, space, and spectators was carried out based on the case of domestic historical museums, and future exhibition space planning or movement lines according to the mutual relationship between the exhibition space and the spectators were conducted. The purpose of this study is to conduct research on specific visualization and data derivation regarding spatial density and spatial perception information.

Contemporary architecture is philosophy and art, and science are different that holds the architecture of human thought and behavior based on a variety of physical space. In addition, the technology is used by the new media graphics, lasers, LED, which were possible only in imagination, using tools such as the time-space of the potential for explosion. In particular, it was found in the spacial color of atypical using the nature of light. Such these architecture is space people actively experiencing a sense towards the expansion of its place. Therefore, the study purpose is to explore the Steven Holl's spacial colors to utilize the space is important to the possibility of light. He prefers the connection to the invisible world is inferred from the visible world and other space. He thoughts an idea linked to the concept watercolors which is a tool that holds to the notion of the flexibility of light and shadow. Concept watercolor is the idea space, establish space, recombinant space, and the growthy space. These have shown the no fixed spacial color cause of the combination of the different tones according to the characteristics of the mixed-color development of a concept watercolors demonstrated the spacial color of the replacement. That is to establish a parody of the works light blending spacial color.

In this paper, we propose a method to segment a color image into several meaningful regions. We suppose that the meaningful region has a set of colors with high frequency in the color image. To find these colors, the color image is represented as several sets of color points in RGB space. And when we use the density of points defined in this method, color belonging to a dense region of color points in RGB space refers to the color that appeared frequently in the image. Eventually, we can find meaningful regions by looking for regions with high density of color points using our level set function in RGB space. However, if a meaningful region does not have a contiguous region of the sufficient size in the image, this is not a meaningful region but meaningless region. Thus, the pixels in the meaningless region are assigned to the biggest meaningful region belonging to its neighboring pixels in the color image. Our method divides the color image into meaningful regions by applying the density of color points to level set function in RGB space. This is different from the existing level set method that is defined only in 2D image.

In this paper, we review the applicability of fog screen to implement 'Spatial Augmented Reality' which displays the image on the whole space of real space or in real space by separating display equipment and user, in contrast to the traditional Augmented Reality. Through three exhibitions and one performance, we confirmed t hat the fog screen, which can be passed through, is a suitable material for implementing the Spatial Augment ed Reality. We found that the hologram production was easier than before because of fog screen. Through the questionnaire survey conducted on performers along with the exhibition, we found that only about half of people know what a fog screen is, and about 10% of the total respondents saw the fog screen. In order to investigate the effect of fog screen on the surrounding space, we conducted an experiment to observe the change of humidity according to the time and distance in the Children's Culture Center of the Asian Culture Center. We found that the humidity within a radius of 5m around the fog screen could increase by 2~3%($6,400m^3$ standard). Thus we provided some safety requirement with fog screen when works made of materials vulnerable to moisture such as paint, paper, and wood are exhibited at the same time with fog screen in the exhibition hall.

The purpose of this study is to research the viewpoint of space practice method through the discussion about social space. The study researched how social practice strategy is unfolded through the understanding about daily life, space manufacture and interaction. As a social practice, space design should adopt the interaction approach method on the basis of social relationship latent in the base of space. As a result of study, the viewpoint of space practice can be summarized into 3 viewpoints as below. First, it is the viewpoint of recognition through the experience meeting daily life. Rural space is the one of experience where daily life and social relationship interact each other. As a delicate sensible experience, it is the recognition of special space detected in the space where daily life occurs. Second, it is the viewpoint of form creation as a media product of society and space. Space is a whole creature of the relationship that has been formed socially as a historical process. Depending on the goal of community, new form is created by sharing the characteristic of space and having sense of kinship. Third, it is the viewpoint of tuning as a practice for subject participation. Rural space is the daily space to practice structured society subjectively through interaction. In the place of subjective life, there should a space practice with the tuning and cooperation method between subject and society. The main vein of space practice, which is analyzed with the discussion about social space, shows that out lives are maintained by space practice and directly connected to social relationship and structure. After all, the space, which is searched for through space design, has a clear subjectivity, ensures abundant subject life and is led to realization of community value.

As appearing on the stage of social media which expands the private relations to the public relations, the Social Intelligence(SI) is made again prominent in our society. The Public Relations(PR) is in particular related to the SI which means the ability to get along well with other people and to encourage others to cooperate with oneself. It points out the necessity of the study with respect to the impact of SI on the choice of educational major and the adaptation of social media in PR, because the SI is one of the important aptitudes which students who major in Communication and PR would need for actual field. But the result of the research indicates that the SI does not influence the choice of educational major of the students who major in Communication and PR. To make those students go into high level of the SI, the students need the specific education which would enhance and reinforce their SI such as the SPACE Program developed by Albrecht and reorganization of curriculum in the education of Communication and PR. Besides, this study shows that the high level people actively use the social media, for example, Smartphone in order to keep their best relationships.
