Article Citation - WoS: 7Review of Literature for the Concept of Post-Disaster Housing in Turkey(Gazi University, 2008) Baradan, BernaThere have been implementations of post-disaster housing even in historical ages and mentioned in studies concerning a specific period in time in which the disaster occurred in Turkey. With a brief overview of such history of post-disaster housing, the studies were reviewed based on the relationship between approaches and time periods concerning the architectural literature of post-disaster housing in Turkey between 1977 and 2005. There are mainly two types of architectural studies about this concept; observations and analyses about the general policy in Turkey, and case specific studies. These two types of studies can also classified within their writing style as well; descriptive style and analytical style of writing is used for a basis for the comparison of approaches used in the studies. The term ‘architectural literature’ used in this article were used for the works published by the architects and/or studies published in architectural magazines. From this analysis, it could be concluded that the architectural society in Turkey changed its point of view to more humanistic solutions in post-disaster housing after the 1999 Marmara Earthquake.Data Paper Citation - WoS: 3Citation - Scopus: 4Experimental data showing the thermal behavior of a flat roof with phase change material(Elsevier, 2015) Tokuç, Ayça; Başaran, Tahsin; Yesügey, Sadık CengizThe selection and configuration of building materials for optimal energy efficiency in a building require some assumptions and models for the thermal behavior of the utilized materials. Although the models for many materials can be considered acceptable for simulation and calculation purposes, the work for modeling the real time behavior of phase change materials is still under development. The data given in this article shows the thermal behavior of a flat roof element with a phase change material (PCM) layer. The temperature and energy given to and taken from the building element are reported. In addition the solid-liquid behavior of the PCM is tracked through images. The resulting thermal behavior of the phase change material is discussed and simulated in [1] A. Tokuç, T. Başaran, S.C. Yesügey, An experimental and numerical investigation on the use of phase change materials in building elements: the case of a flat roof in Istanbul, Build.

Brown, 2011, Surrey and Burlington, Ashgate, 378 pp., $65 (hardback), ISBN 978-1-4094-2117-7 Feminist Practices originates from a traveling exhibition and series of public talks with the same name that took place in 2008 and 2009. As the title suggests, the book presents feminist practices and methodologies in architecture. While doing that, however, we are urged to think outside the box. Firstly, ‘feminist’ in feminist practices is not necessarily ‘female focused’ or ‘gender specific’. Rather, it refers to alternative modes of seeing, researching and practicing. Secondly, architecture is also approached critically, opposing the star system, engaging the client and the community, and challenging usual hierarchies: visual/material, permanent/transient, public/private, labored/expedient, and precious/ valueless (325). In return, feminist practices in architecture refers to explorations on all alternative modes of pedagogy, research and practice that establish new ways of understanding spatial relationships, revise existing power relations and offer possibilities for new interactions and value systems. This is a huge task, but a worthy one. However, there is one problem with the title that needs to be recognized.Article Citation - WoS: 10Citation - Scopus: 11Analysis of the Relationship Between Daylight Illuminance and Cognitive, Affective and Physiological Changes in Visual Display Terminal Workers(SAGE Publications Inc., 2019) Öner, Merve; Kazanasmaz, Zehra Tuğçe; Leccese, F.; Salvadori, G.This study explored the impact of daylight illuminance on cognitive load during visual display terminal use by means of various physiological, performance and subjective measures. Repeated-measures design was adopted to identify the impact of variations in daylight levels that were manipulated through the shading system configurations (shading-on; shading-off). A total of 30 subjects performed visual and cognitive demanding tests. Performance measures were supported by subjective data and eye-related measures during the experimental analysis. Results revealed that the use of a shading system had positive impact on sustained attention. Concerning ocular measures, percentage of eye closure values showed opposite tendencies among vigilance and sustained attention demanding tests. Eye aspect ratio-max and blink duration were significantly correlated with reported glare sensation. In all tests, eye aspect ratio-max was found significantly higher in lower illuminances. Search velocity was significantly correlated with ocular variables in higher illuminances whereas sustained attention showed an opposite trend. This, initially, explains that even slight differences in daylight illuminance might have distinctive effects on the relationship between different groups of assessment variables while measuring cognitive load. Secondly, it proves the significance of carrying out sensitive experiments in terms of both light levels and test characteristics.Article Citation - WoS: 9A Fuzzy Logic Model for Benchmarking the Knowledge Management Performance of Construction Firms(NRC Research Press, 2011) Kale, Serdar; Karaman, Erkan A.Knowledge management is rapidly becoming a key organizational capability for creating competitive advantage in the construction industry. The emergence of knowledge management in this capacity poses enormous challenges to executives of construction firms. This paper proposes a model for benchmarking the knowledge management performance of construction firms that can guide and assist construction business executives in meeting these challenges. The proposed model incorporates benchmarking and knowledge management concepts with fuzzy set theory to adequately handle imprecision, vagueness, and uncertainty that prevail in this process. It uses the fuzzy-weighted average (FWA) algorithm to evaluate the knowledge management performance of construction firms. It is an internal reporting model that can provide powerful diagnostic information to executives of construction firms by evaluating their firm's knowledge management performance, identifying their firm's strengths and weaknesses with regard to each knowledge management practice, and setting priorities for managerial actions related to knowledge management practices that need improvement. A real-world case study is presented to illustrate the implementation and utility of the proposed model.Article Citation - WoS: 3Citation - Scopus: 8Way-Finding Strategies of Blind Persons in Urban Scale(John Wiley and Sons Inc., 2017) Kan Kılıç, Didem; Doğan, FehmiThe aim of this study was to determine whether urban environments with different prominent sensory inputs have an impact on the way-finding strategies of blind people and to identify these impacts, where applicable. We specifically investigated how blind people use their senses to compensate for the lack of visual information and how the priority of senses changes according to the urban context. The participants of the study consisted of nine congenitally blind individuals and the study took place in two urban settings: a dense urban district, Kemeralti district in İzmir; and an urban park, the İzmir Fair Park. During the learning phase, a first trial along the selected routes was conducted for each participant individually along with one of the researchers. In the test phase, the participants were requested to re-walk the route and verbally report the environmental cues they attended to. The participants’ verbal reports were recorded and transcripts of the recordings were coded according to the environmental sensory inputs. In addition, the short-term memory of each participant was also evaluated. The results show that the characteristics of the urban environment seem to have an impact on way-finding strategies of blind individuals. It was found that the sound of the city and the echo from the environment are the most important factors for blind participants in the dense urban environment. Environmental boundaries provided echoes and gave a sense of enclosure that helped them orient themselves, whereas, in the park environment, the sense of enclosure was not enhanced due to a lack of boundaries in the environment.Article Citation - WoS: 18Citation - Scopus: 21Experimental and Numerical Investigation of Forced Convection in a Double Skin Façade(MDPI Multidisciplinary Digital Publishing Institute, 2017) İnan, Tuğba; Başaran, Tahsin; Erek, AytunçFlow and heat transfer of the air cavity between two glass façades designed in the box window type of double skin façade (DSF) was evaluated in a test room which was set up for measurements in the laboratory environment and analyzed under different working conditions by using a computational fluid dynamics tool. Using data from the experimental studies, the verification of the numerical studies was conducted and the air flow and heat transfer in the cavity between the two glass façades were examined numerically in detail. The depth to height of the cavity, the aspect ratio, was changed between 0.10 and 0.16, and was studied for three different flow velocities. Reynolds and average Nusselt numbers ranging from 28,000 to 56,500 and 134 to 272, respectively, were calculated and a non-dimensional correlation between Reynolds and Nusselt numbers was constructed to evaluate the heat transfer from the cavity (except inlet and outlet sections) air to the inside environment and it could be used the box window type of DSF applications having relatively short cavities.Article Citation - WoS: 13Citation - Scopus: 25A Diagnostic Model for Assessing the Knowledge Management Practices of Construction Firms(Korean Society of Civil Engineers, 2012) Kale, Serdar; Karaman, Erkan A.Knowledge management is rapidly becoming a key organizational capability for creating competitive advantage in the construction industry. The emergence of knowledge management as a key organizational capability for creating competitive advantage poses enormous challenges to executives of construction firms. This paper proposes a model for benchmarking the knowledge management practices of construction firms that can guide and assist construction business executives to meet these challenges. The proposed model incorporates benchmarking and knowledge management concepts with Importance-Performance Analysis (IPA) and Comparative Performance Analysis (CPA) maps. The IPA and CPA maps are visual management tools that have been commonly used for continuous improvements in processes and the performance of firms. Yet they have not been used in the construction management literature or for evaluating the knowledge management practices. The proposed model can be used by construction firms as an internal performance measurement tool to evaluate their knowledge management practices. It can provide powerful diagnostic information to construction business executives of construction firms in order to evaluate their firm's knowledge management practices, identify their firm's comparative advantages and disadvantages with regard to each knowledge management practice, and set priorities for managerial actions related to knowledge management practices that need improvement. A real-world case study was conducted by administering a survey to 105 construction firms operating in Turkey and is presented to illustrate the implementation and utility of the proposed model.
