  • There has been preconceived assumption that, in good architecture, exterior and interior have to be harmoniously related to each other. However, in contemporary architecture, it is easy to witness that this harmonious relationship between exterior and intoner is severely challenged and various exterior surfaces have multi-faceted roles. Rem Koolhaas explained this sort of new situation in the light of 'lobotomy' that is a surgical method for mental disorders, based on the high-rise buildings in the early Manhattan. This study is started with the Rem Koolhaas' lobotomy concept and how this concept is applied to his projects. The multiple roles of exterior surface can be also found in many contemporary architects' projects. Among them, Jacques Herzog & Pierre do Neuron and Toyo Ito's recent projects are discussed to further analyze the new roles of surface and compared with Rem Koolhaas' case. Although the architects discussed present very limited scope of what is happening on the surface of comtemporary architecture, it is hoped to disclose some examples of new relationship between exterior and interior.

  • In recent years, risks associated with mixed used development in urban regeneration projects which have actively been implemented have been on the rise due to uncertainties and complexities of those projects. Thus, risk management is needed to effectively manage those risks that may occur during the process of a project. Many studies have contributed to deal with risk management of those projects. These studies, however, have focused main on identification stage and deriving the main risk factors and have limitations on presenting the relationship among those risk factors. Since many risks are interdependent and have multiple effects, the purpose of this study is to present a way(ISM method) to provide a hierarchical structural framework of risks in Urban Regeneration. The structural of risks can helps decision makers to trace the actual source of these risks.

  • In Jamaica Kincaid's novel Lucy, the narrator grows up with the burden of colonial legacies embedded with Englands' imperial disciplinary projects, its language, educational institutions, discourses. Colonial education interpellates the narrator into a colonial subject through its multiple ideological discourses and systems. Teaching the literature of England is the most insidious form of the Empire's disciplinary colonial projects, more powerful than military enforcement: Its mode of operation is creating phantasy and instigating and planting desire for such phantasy. As Homi Bhabha aptly theorizes as colonial mimicry and ambivalence, the narrator as colonial subject grows up split and confused as an ambivalent subject, simultaneously mimicking and desiring for the phantasized England as real, while resisting and criticizing such up-bringing and mimetic desire. This paper explores Kincaid's rhetorical strategy of employing Wordsworth's poem, "I Wandered as a Lonely Cloud," especially her use of the flower "daffodil." Employing the concept of "daffodil gap" suggested by postcolonial critics, this paper closely examines two episodes involving the flower daffodil in the novel, one in a colonial classroom and the other in a garden in a new world and suggests that Kincaid accomplishes intertextual critique of colonial education and imperial projects.

  • In the recent years, a variety of projects have been conducted in order to enhance competitiveness of leading businesses and their followers in the market. Accordingly, the importance of project portfolio management has risen in the open market industry. Project portfolio management refers to crucial decision-making processes which aim to maximize benefits by selecting projects most suitable for a strategic objective among multiple projects with limited resources. In this study, the trend of project portfolio management studies is introduced. The study also presents a mathematical model of the problem, which aims at maximizing project values, possibility, and similarity between projects in the limited resources. We use the genetic algorithm to obtain the priority orders of projects. In order to verify this study, we compare the results of this study and the existing schedules of the E-open market in South Korea. This study ultimately reduces project risks, improves efficiency of development and continuity of tasks by properly ordering projects and assigning developers to the projects.

  • Nowadays, using math logic in great civil projects is considered by the clients to achieve the goals of project including quality optimization, costs, avoiding individual, emotional and political decision making, long-term and short-term goals and they are the main requirements of each project and should be considered by the decision makers to avoid the illogical decision making applied on the majority of civil projects and this imposes great financial and spiritual costs on our country. The present study attempts to present one of the civil projects (Ghasre Shirin storage dam) whose client was not ministry of energy for the first time and the short-term and long-term goals of the private sector were applied based on the triangle of quality, cost and time. Also, the math logic and model (multi-criteria decision making method and decision making matrix) is used in one of the most important sections of project, sealing element, policies and new materials (Geosynthetics) are considered and this leads to suitable decision making in this regard. It is worth to mention that this method is used for other sections of a dam including body, water diversion system, diaphragm and other sectors or in other civil projects of building, road construction, etc.

  • The maintenance of educational facilities is divided into inspection and management of facility managers residing in the school and Educational Environment Improvement Projects(EEIP) to carry out maintenance work. Educational support organizations collect maintenance requests through facility inspections by school-specific facility managers, and carry out numerous maintenance projects during the year. The EEIP has the characteristic of Program Management with interrelationships between projects, not multiple projects management. The purpose of the EEIP is to eliminate the inconvenience of school facility users and increase their satisfaction, and achieving the goal is judged to be successful. Despite the importance of management and performance measurement utilizing Critical Success Factor(CSF) for the operation of successful educational facility maintenance management programs, the system for achieving the goals is insufficient. This study derives CSFs for each stage of the EEIP for the success of the EEIP. The CSFs for each stage of the EEIP is expected to serve as a basis for evaluation of educational facility maintenance management programs and can be used as an evaluation index in the future.

  • This study aims to analyze the multiple meaning of color variously expressed in contemporary architecture. Nowadays heterogeneity, plurality and ephemerality of modem society have been well presented in contemporary architecture. The phenomenal characteristic of color is so appropriate to express the unfixed and immaterialized attributes of contemporary architecture that it can make color a major element of architecture, which, in the past, used to be a minor element for the lack of materiality. Through the analysis of contemporary important building projects in terms of color, it can be concluded that the architectural application of color shows multiple meanings as follows; phenomenal expression, visualization of complex programs and embodiment of design process, reflection of context and control of users' mentality. At the same time, these multiple meanings are complexly presented in a single building project.
