Security has been a major concern in software development. Security tactics are reusable building blocks providing a general solution for recurring security concerns at the architectural level. They are often used together with architectural patterns which provide a general solution for architecting software systems. However, use of security tactics in architectural patterns has been understood only conceptually without concrete understanding of how their involved elements should be structurally and behaviorally co-designed. In this paper, we present model-driven analyses of security tactics in the context of Broker architectural patterns and provide evidences of the analyses in real world case studies.

The purpose of this study is to identify the legal definition and usage of cultural property term related to the architecture within the cultural property-related legal system and general legal system, and to present proper terminology and specific concepts that can be used for the architecture as cultural properties. In the current cultural property legislative system, terms about the architecture are diverse and obscure, and the definition of each term is different from the concept in the general legal system. In this context, this study presented the terminology of 'the architectural heritage' as 'a cultural property by construction act' to cover whole cultural properties related to Korean architecture. And the conceptual scope of the architectural heritage is divided into the technology and the performer related to the act, the record and the building related to the product. and Each concept needs to be specifically tailored to its object and scope. Systematic definition of terms for cultural properties related the architecture can positively influence systematization of cultural property preservation and management as well as empirical research and education on Korean architecture.

The notion of materiality in architecture has existed throughout its history, and it has begun to discussed in earnest as an important architectural discourse since early twentieth century, when the Industrial Revolution and its consequent mass-production system has fundamentally changed the means and methods of architectural production. However, this traditional notion of materiality is not fully engaged with today's digital paradigm, and not able to inquire into the complex aspects of contemporary architectural process, because their theoretical and perceptional bases are still remaining in modern era. In this shifting context, this study is intended to develop a new concept of digital materiality which corresponding to contemporary digital and material culture. This paper speculates and argues digital materiality as an active ingredients of contemporary design process as well as a comprehensive logical system that negotiate with various geometric conditions. The purpose of this study is to analyze and investigates the distinctive characteristics of Office dA's architectural design process in the digital realm.

In this study, the change of critical elements of the design evaluation was investigated during two decades at the architectural competition which was held nationwide in Germany. Specifically, the periods of investigation span both from July 1989 to June 1990 and from July 2009 to June 2010. The results of the analysis show that the cost of construction, the maintenance cost, the design of facade and the energy conservation are being magnified for the new important elements. The images of buildings and the economic aspects are meant to be high. The frequency of the critical elements for interior spaces is approximately two times more important than those for the forms and outdoor spaces. Overall, many juries of the architectural competition in Germany were interested in the elements for interior spaces. The field of function accounts for roughly the half of four basic architectural fields such as function, others, aesthetic and construction fields. The critical elements are required persistently such as context, Circulation, organization of space, form, landscape and outdoor space design, arrangement of building, cost of construction, function, design of facade, location of main entrance. These items are regarded as the most important elements of the design evaluation at the competition. Knowing the change of critical elements of the design evaluation, we can understand the trend of architecture in Germany. The results of this study can be applied in Korea to develop the critical elements of design.

Because the 'image' is the 'reality' in this era, there are the characteristics dematerialized between reality and non-reality in the contemporary architecture. These are promoting individualization, differentiation and multi-layered time with the development of electronic technology. This trend emphasizes the importance of imagines that are not only homogenized, simultaneous but also overlapped, multi-layered, discriminatory. Perspectives and essential characteristics of the architectural skin are changing in terms of the technical and social awareness and that means the skin has features as a complex body. Recently as an imagine creator, the architectural skin make form of media boundaries reflecting the various relationships between the observer and the external environment and also, the interior space become another sensory skin by removing the boundaries of the internal and external. It is important that making an identity of the architecture defined by the media or the imagine as well as the importance of space in architecture. These changes of skin make the third space based on the viewer's imagination and show the potential of new architectural skin with the expansion space by blurring the boundary between reality and illusion. It occurs to the diversity of the architectural skin with the identity. It will more diversified and be recognized immediately and sensibly through the interface attributes in contact with the city directly. In addition, it is more important that the skin become a unified body related with urban, social and cultural context.

Owing to the advent of ubiquitous computing technologies, the concept of Intelligent Environments has emerged, as an alternative approach to overcome the limitation of the built environment. Intelligent Environments can be more responsive to user-and context-specific human activities by automatically and dynamically modifying their settings without explicit human intervention. However, the conventional approach to the development of Intelligent Environments has mainly focused on the technical issues without paying much attention to the dynamic interrelationship between the user and the built environment. Therefore, differing or conflicting needs of multiple simultaneous users remain unresolved. The objective of this study is to present types of environmental conflicts and their resolution through agent collaboration and negotiation. For the demonstration and validation of the conflict resolution process, a set of hypothetical test cases is simulated in a 3D test environment. The result of the case simulations shows that the proposed approach is computationally feasible and applicable to the development of Intelligent Environments, and, furthermore, it can overcome the drawback of the conventional approach.

I proposed the architectural guideline for educational environment based on design thinking approach to integrate and enhance learners' activities and achievements. The physical environment of design education learning space should be applied by teaching methods and learning activities, especially for STEAM-based convergent education, the architectural space conditions should support the design process based on design thinking. The learning environment conditions influence design education with physical design factors and learners' communication, and the flexible environment based on design thinking, which is crucial for design education. The 3 steps of design thinking experiences also allow students to learn the context of ideas, skills and outcomes. Therefore, I argued that the learning surrounding based on design thinking needs flexible and mobile, connected, integrated, organized, and team-focused environments to support learners' understanding, participation, and collaboration, and to achieve the design process based on research findings. For spaces for convergent learning environments based on design thinking, common design principles should be reviewed, such as coexistence with technology, safety and security, transparency and spatial extension, multi-purpose space and outdoor learning.

Construction industry still requires a lot of laborers to perform a project despite of advance in technologies, and improving labor productivity is an important strategy for successful project management. Since repetitive construction works exhibits learning effect, understanding laborers' learning phenomenon therefore allows managers to have improved labor productivity. In this context, previous research efforts quantified individual laborer's learning effect, though numerous construction works are performed in group. In other words, previous research about labor learning assumed that sum of individual's productivity is same as group productivity. Also, managers in construction sites need understanding about group learning behavior for dealing with labor performance problem. To address these issues, the authors investigate what variables affect laborers' group level learning process and develop conceptual model as a basic tool of productivity estimation regarding group learning. Based on the result of this research, it is possible to understand forming mechanism of learning within the group level. Further, this research may contribute to maximizing laborers' productivity in construction sites.

Demand is increasing for large, high-rise, and complex buildings, which is leading to advances in the development of high-performance structural systems. In this context, precast concrete (PC) technology has received a large amount of attention owing to its benefits in terms of schedule reduction, high quality, and easy installation. In addition, advanced methodologies that improve the PC performance by the addition of various materials have recently been reported. Research on analyzing the effects of such high-performance PC on the construction process and productivity is very limited. This makes it difficult for decision-makers to apply PC to particular projects. Thus, the aim of this research was to analyze the work productivity of the high-performance PC slab installation process by using a construction simulation tool to resolve critical issues. In this study, a real construction project that adopted PC slab installation work was analyzed, and a sensitivity analysis was performed to confirm the reliability of the analysis results.

The purpose of this study aims to investigate the characteristics of architectural association methods which apply Hall's poetic concept by looking into how Hall extracts languages and images under what circumstances and by analyzing how the extracted elements are integrated into an architectural space through what association processes. First of all, poetic association functions in the architectural process are compared, and the value of using visual associations in architectural designs are investigated based on the results of the analysis. Next, Steven Holl's poetic concept is investigated in the context of the concept extraction step, the idea expansion step, and the space composition step in order to find out how such association methods work in the process of architectural designs. The methods of reproducing, changing and using Steven Holl's poetic concept can be summarized as follows in relation with experiential associations, multi-meaning associations and morphology associations: 1) Steven Holl's experiential associations are a method of expressing perceived images in the form of languages in the process of interpreting land and programs. This method has the characteristics of reproducing various architectural ideas by generating a relationship between invisible characteristics of land in images and languages. 2) Steven Holl's multi-meaning associations are a method of directly associating a project with related objects and incidents, or of coming up with a hidden meaning. It has the characteristics of changing ambiguous images of metaphoric, figurative or ironic languages into concrete architectural images. 3) Steven Holl's morphology associations is a method of expressing morphology images and languages which are directly related to the images. Morphology associations have the characteristics of regenerating sensory experience elements into languages or images, which can be seen experiential associations; or they use metaphoric images in architecture by substituting them with other architectural elements, which can be seen in multi-meaning associations.
