The unexpected expansion of the built environment has allowed for high-density and high-rise buildings. As high-density dwellings compromise privacy, the requirements for balancing between interacting with others and protecting privacy are increasing. In this respect, Korean traditional architecture provides privacy through a proper balance of openness and closure in the courtyard garden. However, it is difficult to analyze privacy quantitatively, as it depends on the individual experience and psychology. The analyzing for visual privacy is a significant issue to resolve a conflict with others and enhance human's comfort. Therefore, this paper addresses the assumption that visual privacy could ultimately be quantified based on the concept of prospect and refuge, one of the design strategies for psychological wellbeing. The purpose of this study is to examine visual privacy in the royal palace in Korea, Gyeongbokgung and Changdeokgung. It measures spatial configuration in each buildings using space syntax, and the area ratio of prospect and refuge through an image analysis with Adobe Photoshop CS6. The mathematical properties of connectivity, depth, control value, integration and the area ratio of prospect and refuge are partially available for quantifying visual privacy in buildings.

The present study explored the applicability of Visibility Graph Analysis (VGA) techniques to workplace design research. Six types of VGA measures in Depthmap encompassing visual connectivity, three types of visual integration, mean depth, and visual entropy were employed for the analysis of individual privacy for task concentration and group relationship behavior in the open-plan office environment. Data comprised 136 workers in 6 open-plan offices filled with low-paneled (1.2-1.5m) cubicle workspaces. For the statistical analysis, Spearman's rho correlations and t-tests were applied for the spatial and behavioral measures. The results showed that workspace VGA measures have a potential to be useful information to account for workers' concentration privacy and, limitedly, also informal relationships with team members. Visual entropy values especially offer reliable information to predict various aspects of office workers' privacy behavior while visual integration can be used to account for the workers' sense of trust in group relations. The study also discussed the limitation of VGA applications to the workplace context.

A novel privacy-protection device to prevent visual hacking is realized by using a directional backlight and facial recognition. The proposed method is able to overcome the limitations of previous privacy-protection methods that simply restrict the viewing angle to a narrow range. The accuracy of user tracking is accomplished by the combination of a time-of-flight sensor and facial recognition with no restriction of detection range. In addition, an experimental demonstration is provided to verify the proposed scheme.

This study intends to understand the visual experience of architectural space generated by users' movement based on the interpretation of visual properties. An analytic theory of Isovist is suggested for the objective and comparable measurement for such visual experience, and a computer program for the analysis has been proposed as well. By using the analytical theory and computer program, eight houses designed by Adolf Loos and Le Corbusler are analyzed for the purpose of understanding the visual characteristics of the Modern Architecture and the contemporaries. The result shows that, while the architectural space of Loos emphasizes personal privacy as for being livable spaces, the architectural space of Corbusier emphasizes users' movement as for including diverse visual arrays. These commensurable results exhibit that the analytical tool and research frame suggested in this study can be a competitive tool for such analysis.

Korean personal data(information) protection law requires privacy policies post on every website. According to recent survey results, users' interests on these policies are low due to these policies' low readability and accessibility. This study proposes a layout that effectively conveys online privacy policy contents, and assesses its impact on information understandability, vividness, and recognition of users. Studies on privacy policies and layouts, media richness theory, social presence theory, and usability are used to develop the new layered approach. Using experiments, three major layouts are evaluated by randomly selected online users. Research results shows that information understandability, vividness, and recognition of privacy policies in the revised-layered approach are higher than those of in the text-only or table-based layouts. This study implies that employing visual guides like icons on privacy policy layouts may increase users' interest in those policies.

After the rapid growth of economics in South Korea 1960'1, the number of workers in the whole land in-creased day after day along with the growth of industry. As the growth of the third industry occurred quite rapid-ly, the rate of office workers went up high. Accordingly the business office has been changed the primary work-ing space and recognized the main space as much as the living space. As a result of conceptual change about working place, the business office has an important ef-fect on worker's liberal and psychological environment. In order to provide the office workers with the office work-ers with the suitable and convenient working environ-ment, Socio-psychological factors were first considered at the first stage of construction planning. In this paper, I would understand both how office workers take up their attitudes of Socio-psychological point according to the office type and what they claim for their office environment. This understanding offers us fundamental data in office plan. This paper starting from this purpose got the following conclusions. *Office workers are violated their hearing privacies rather than their visual privacies. They are dissatisfied with ensuring their own spaces and satisfied with their nature of domain. *In the feeling of satisfaction by office type, they are on the whole satisfied with their hearing privacies, their visual privacies, their own space, and the nature of do-main in the closed type and mixed type offices. In open type offices, their visual privacy is often violated. *In the property by individual, men feel more violated their hearing privacies than women. In the personal spa-se and domain, women are less stabilized psycholo-gically than men. *The analysis of the attitude by position, a man of po-sition is more violated his hearing privacy and does not understand each other. The common run of workers are violated their visual privacies and the nature of separa-tion.

The purpose of this study is to provide empirical and quantitative analysis on user's perceived privacy, security, and user satisfaction when providing visualization information about objects and service provider behaviors that users can not perceive in internet service process. Through previous research, we have examined the importance of privacy and security factors as a key factor to be considered for the characteristics of the Internet of things and the Internet of things. In addition, service blueprint, which is one of the service design methodologies to examine the flow of service usage in providing Internet service of things, was examined. In the flow of things internet service utilization, it is found that the things that are out of the user's cognitive area and the behavior of the service provider take up a large part. Therefore, the hypothesis that the trust of the Internet service security and the satisfaction of the user experience can be improved by providing the security visualization information about the behavior of the object and the invisible service provider in the non-contact aspect of the user and the object. In order to verify the hypothesis, we conducted experiments and questionnaires on the use of virtual objects' internet environment and conducted statistical analysis based on them. As a result, it was analyzed that visual information feedback on non - contact and invisible objects and service provider's behaviors had a positive effect on user's perceived privacy, security, and satisfaction. In addition, we conclude that it can be used as a service design evaluation tool to eliminate psychological anxiety about security and to improve satisfaction in internet service design. We hope that this research will be a great help for the research on application method of service design method in Internet environment of objects.

Hayakawa Kunihiko introduced community space as an open space in Housing in Japan for the first time. We can find the continuity of his architectural intent from his three works (Atrium, Steps, Labyrinth) during the early period of his Housing buildings, In particular, from Labyrinth, his intent was expanded to cities through 'Urban Void', seeking communication and harmony. Accordingly, based on the architectural overview and a field survey of Labyrinth, an analysis was conducted using Space Syntax to investigate whether the space of an inner courtyard is being used as a community space for neighbors who pass through the courtyard and whether the courtyard plays the role of 'Urban Void' as intended by the architect. For this investigation, according to VGA, the courtyard showed the role of great visual connectivity and integration and facilitated connections to the center of the entire space. On the other hand, according to J-Graph, the access stairway connected to each household from the courtyard helped secure privacy in the midst of common space. Step Depth noted that a hierarchy of space was formed to ensure visual privacy within each unit household in addition to privacy for each household.

This study attempts to suggest new directions of urban multi-family housing design in the recent era of information, in which the representation of publicity and privacy of the housing reflects new meanings and relationships of the current digital society. The study examines cases of Dutch multi-family housing and investigates the meanings and relationships of publicity and privacy in the building as well as unit design of the housings. Borneo-Sporenburg housing development is a good example that suggests new interpretation and design solution for low-rise, high-density multi-family housing. Thus, this study analyzes street patterns, facade design, and ways of housing unit combination in Borneo-Sporenburg housing and concludes as follows. First, public space in Borneo-Sporenburg housing, which was designed differently from hierarchical and centripetal organization of modern architecture, is divided into small units and spread into the inside, which provides high potential for personal control of space and personal programming of space by space choices. Second, street pattern and facade design of Borneo-Sporenburg housing provide visual publicity and privacy simultaneously as they maintain unity as a whole as well as articulate individual unit in many different ways and provide clues to neighboring. Streets as a public domain have self-controlled boundaries for residents and introduce voluntary use-programs for residents. Third, facades of the housing have no inter-mediate space or common space, and confront streets directly. Space in-between is composed inside the facade and extends into the streets by residents' own choices. Fourth, privacy and individuality of the housing is strengthened. Units of the housing have individual entrances, unique plan type and complicated combination of space that all together emphasize individuality of units, however they are not often notified from the outside.

I suggested the design learning environment based on affordance concept approach for supporting and improving learners' behavior and outcome for convergent design education in this study. The design learning space should be applied teaching and learning activity, especially learners' behavior, physical space condition to support the design thinking process. The design learning space needs openness, individuality and connectivity to support the learners' behavioral to immerse, participate, cooperate, understand, think and fulfill the design thinking process. The composition principles of the learning environment for convergent design education supports communication and collaboration among members for independence and interaction. The spaces for design research and teaching needs high privacy while facilitating visual communications through special materials and wall structure design. Also, for connectivity to improve the learners' physical and visual contact, the environment of the classrooms requires flexibility and mobility by providing an open space integrating unit cells for realizing learning purpose. These are provided by formed of an open structure for inducing visual communication and physical contact to involve the design activities and the mutual interchange.
