A comparison of the cognitive actions of designers in geometry-based and parametric design environments
(Open House int, 2020) Tunger, Cetin; Pektas, Sule Tasli; 272043; İç Mimarlık
Purpose - This paper aims to compare designers' cognitive behaviors in geometry-based modeling environments (GMEs) and parametric design environments (PDEs). Design/methodology/approach - This study used Rhinoceros as the geometric and Grasshopper as the parametric design tool in an experimental setting. Designers' cognitive behaviors were investigated by using the retrospective protocol analysis method with a content-oriented approach. Findings - The results indicated that the participants performed more cognitive actions per minute in the PDE because of the extra algorithmic space that such environments include. On the other hand, the students viewed their designs more and focused more on product user relation in the geometric modeling environment. While the students followed a top-down process and produced less number of topologically different design alternatives with the parametric design tool, they had more goal setting activities and higher number of alternative designs in the geometric modeling environment. Originality/value - This study indicates that cognitive behaviors of designers in GMEs and PDF-s differ significantly and these differences entail further attention from researchers and educators.

Audio-Visual Interactions and the Influence of Colour on Noise Annoyance Evaluations
(Springer Singapore Pte Ltd, 2021) Kitapci, Kivanc; Akbay, Saadet; 275153; 21742; İç Mimarlık
This study aims to examine the influence of colour exposure on noise annoyance. Previous studies in the literature have focused mostly on the effects of colour exposure on loudness judgements; however, due to the cognitive nature of multisensory perception, the influence of colour on noise annoyance also needs to be investigated. Our experiments were designed to administer non-information-carrying sound signals (i.e. white noise) and visual stimuli (i.e. abstract colour samples) and to limit visual and auditory contextual information. Participants were asked to evaluate noise annoyance on an 11-point International Commission on Biological Effects of Noise (ICBEN) scale. The experiments were conducted in the form of audio-visual tests. During these tests, random combinations of three white noise sound samples with sound pressure levels of 66 dB(A) (-4 dB[A] acoustic condition), 70 dB(A) (0 dB[A] acoustic condition) and 74 dB(A) (+4 dB[A] acoustic condition), and six visual stimuli, including the elementary colours of the Natural Colour System (NCS)-yellow (Y), red (R), blue (B), green (G), white (W) and black (S)-were presented to a total of 42 participants. The black colour sample was used to measure the audio-only control condition for the three white noise sound samples. The results of the study reveal that the effects of sound, the effects of colour and the interaction effects of colour and sound on perceived noise annoyance were statistically significant. The effects of colour on the loudness evaluations of the previous studies and the effects of colour on noise annoyance evaluations presented in this study show very similar and concordant results, indicating that the effects of colour on noise annoyance depend on the sound pressure level (SPL). The results indicate that the hue contrasts of red-green, red-blue and yellow-blue and the lightness contrast of yellow-blue influenced perceived noise annoyance when the SPL was low or high. Within the contrast pairs, red and yellow were perceived to be annoying, whereas blue and green were perceived to be non-annoying.

Comparing Turkish and European noise management and soundscape policies: a proposal of indoor soundscape integration to architectural design and application
(Mdpi, 2019) Ercakmak, Ugur Beyza; Yorukoglu, Papatya Nur Dokmeci; 214925; İç Mimarlık
Improving soundscape studies and policies states that the soundscape approach, which also considers noise interventions, should replace noise management. However, a considerable number of soundscape studies have been concerned with the quality of acoustic environments of open and urban public spaces. This study focuses on indoor soundscaping and its possible integration into the architectural design and application process. Therefore, the present and ongoing Turkish and European soundscape and noise management policies were evaluated in detail and compared in order to characterize the gap regarding the state of indoor soundscaping between the literature and the policy development level. Furthermore, we identified and classified factors and methods which have an influence on indoor soundscaping to be integrated into the final proposed model. As a result of the detailed evaluation regarding policies and indoor soundscaping principles, five stages were proposed that can be used in an integrated indoor soundscape model: (1) the establishment of a topic specific institution or working group on indoor soundscaping; (2) the preparation of a standard that includes definitions, indoor soundscape factors and methods; (3) the preparation of an indoor soundscape directive; (4) the preparation of indoor soundscape guidelines; and (5) the provision of maintenance and supervision by experts and authorities.

Construing colours using repertory grid technique: An idiographic approach in colour perception
(Wiley, 2022) Akbay, Saadet; Borekci, Naz A. G. Z.; 21742
This article offers an alternative methodological approach to the exploration of subjective experiences by studying individuals' personal views of perceived colours. The study aims to investigate the construals of individuals related to perceived colours using an idiographic approach. The subjective approach proposed is based on the theory of personal construct psychology and the methodology of the repertory grid technique. A repertory grid experiment was conducted to determine individuals' ways of construing colours and examine the collective understanding of the content and structure of individuals' construals concerning perceived colours. Sixty undergraduate students participated in the experiment, yielding 60 different repertory grids that included a number of personal constructs indicating the construal process of participants in differentiating between 11 basic colours. Participants produced their own semantic bipolar dimensions for comparing the perceived colours and creating differential ratings according to their personal constructs. The elicited data were evaluated using qualitative content analysis to understand the differences between individual systems of constructs and investigate the commonality of shared constructs relating to colours. The data were also analyzed quantitatively to investigate the common structure of and interrelationship between elicited constructs and perceived colours. The outcomes have the potential to contribute to academic and practical knowledge concerning colour perception, as well as encouraging further studies with an idiographic approach.

Development and testing of Indoor Soundscape Questionnaire for evaluating contextual experience in public spaces
(Sage Publications Ltd, 2017) Dokmeci Yorukoglu, Papatya Nur; Kang, Jian; 214925; İç Mimarlık
An Indoor Soundscape Questionnaire aiming at the evaluation of indoor public sound environments was designed, statistically tested and presented. It was established through initial pilot studies and three main factors under contextual experience variable are established as (1) psychological factors, (2) space usage factors and (3) demographical factors. In addition to the questions on demographical and space usage factors, detailed questions on psychological factors are designed and statistically tested for expectation, perception and reaction categories of the psychological factor. The questionnaire was applied as part of a case study in enclosed library foyer environments to a group of 270 participants through non-experimental survey data sampling. The reliability and validity scores of the Indoor Soundscape Questionnaire were statistically tested and confirmed. Furthermore, statistical tests were used to derive relationships between contextual experience variables of psychological, space usage and demographical factors. Chi-square test of goodness-of-fit results showed statistical significances of demographical and space usage factors with the psychological factors.

Heuristic and analytic color decision making in the introductıry design education
(Wiley, 2017) Ural, Sibel Ertez; Akbay, Saadet; Altay, Burcak; 21742
Color comprises both subjective and objective aspects within its contextual nature. Research on color design tends to explore this seemingly contradictory concerns from theoretical point of view, as well as architectural and design practice. The aim of this study was to observe subjective, intuitive or heuristic and objective, knowledge-based or analytical attitudes toward color in design education. In the study 84 introductory design students were surveyed progressively to understand their color decision criteria after completion of three 2-dimensional colored exercises, specific in terms of color education. Students' responses to open-ended questions were coded according to the 5 categories, under 2 decision making processes derived from the literature; heuristic approach: preferential and symbolic criteria, and analytic reasoning: formal, thematic, and systematic criteria. A distinction between associative and emotional aspects of symbolic criteria was also revealed by the data analysis. The findings showed a shift from heuristic responses to analytic reasoning, as expected. Additionally, it is also investigated that students not only used heuristic approaches but also analytical components (formal and systematic) of color decision making in varying degrees as well, even before any color subjects covered. Thematic color decisions became a major part of the students' design considerations upon completion of color subjects. The observed increase in the number of color criteria interrelated by the students' among almost all categories explicated a complex decision making process particularly in color design and education. These findings were expected to lead to some further understanding in color decision making in design.

Indoor soundscape perception in residential spaces: A cross-cultural analysis in Ankara, Turkey
(Sage Publications Ltd, 2020) Mohamed, Mohamed Ali Elghadaffi; Yorukoglu, Papatya Nur Dokmeci; İç Mimarlık
Studies in the literature suggest that factors influencing soundscape perception are based heavily on sound environments and auditory perception. Nevertheless, in studying the soundscape perception of people living in certain acoustic environments, cultural, social and habitual criteria should be taken into consideration. Residential environments are where people spend most of their time. Therefore, understanding the soundscape perception in the residential context is significant for indoor soundscape studies. This research investigates the residential soundscape perception differences of two different culture groups living in Ankara, Turkey. A total of 405 Arab and Turkish residents are included in the study. The questionnaire findings are statistically analysed using one-way analysis of variance and t-test. The results suggest that the sound environment in a house setting is equally important for both culture groups, while the Arab residents showed a higher satisfaction level from their present sound environment in their residences. Furthermore, statistically significant differences have been found based on cultural variances of the two groups regarding the overall soundscape perception, sound source loudness, frequency of occurrence, and sound favourability evaluations.

Investigating the restorative potential of women’s home environments
(Springer, 2023) Aksel, Elif; Imamoglu, Cagri; İç Mimarlık
Although research on restorative environments suggest that natural settings have therapeutic effects in moderating stress and promoting positive experiences, there is a limited body of literature inquiring about the therapeutic potential of interior environments. The aim of the current study was to understand the restorative potential of home environments regarding theoretical background on restorative environments and architectural dimensions influencing well-being through the experiences of women. We interviewed 11 adult women using the photo-elicitation technique to investigate the perceived restorativeness of their home environments. Thematic analysis of qualitative data indicated that the design attributes of spaces play a significant role in promoting the restoration process. In addition to design attributes, we found family interaction, socialising, and engaging in activities could also be influential. Furthermore, the exploratory nature of the research highlighted the significance of individual meanings and personal factors in shaping the perceived restorativeness of home environments. Theoretical and practical implications of the findings are discussed to encourage future research in related fields that explore the relationship between residential settings and well-being.

Neighborhood location and its association with place attachment and residential satisfaction
(Emerald Group Publishing Ltd, 2020) Aksel, Elif; Imamoglu, Cagri; 275155; İç Mimarlık
Purpose - This paper aims to investigate the assneiation of neighborhood location with place attachment and residential satisfaction. Design/methodology/approach - First, the authors reviewed the literature on place attachment and residential satisfaction, and then generated a questionnaire based on the scales from the literature. The authors surveyed 135 respondents in two neighborhoods of Ankara, a metropolitan city in Turkey: one in the city center, the other in a suburb. To analyze the data, first, factor analysis. and later, multivariate analysis of variance and correlation tests were conducted. Findings - The results indicated that place attachment and residential satisfaction were positively correlated, in congruence with the related literature; however, neighborhood location appeared to be associated only with residential satisfaction. The theoretical and practical implications of the results are discussed with respect to the recent issues on housing. Originality/value - The effects of neighborhood location on place attachment and residential satisfaction (by comparing two different residential areas of the city) have not been adequately examined in earlier studies. The study results provide an understanding of the effectiveness of residential location on improving place attachment and residential satisfaction and contribute to the existing literature Although the study findings may not be generalized to other locations in Turkey, this study contributed to the previous studies on place attachment and residential satisfaction by providing data from Turkish residents, which is less often examined.

Semiotic interpretation of a city soundscape
(Walter de Gruyter Gmbh, 2019) Yorukoglu, Papatya Nur Dokmeci; Onur, Ayse Zeynep Ustun; 214925; Mimarlık; İç Mimarlık
This work presents a semiotic perspective of aspects of a soundscape evaluation of the city, Supino located in the Province of Frosinone in the Italian region of Lazio. The data and sound sample collection was accomplished through the soundwalk technique undertaken by students of Cankaya University, School of Architecture during the 'Third International Summer School in Supino' 17-24 August 2014. For the soundscape evaluation, three zones were identified in Supino as urban, suburban, and intersection. A total of nine samples across three zones were collected during three different times in a day by soundwalks from the areas located in the identified zones. A theoretical model of semiotic interpretations of soundscapes has been proposed and applied for the analysis of Supino's soundscape. The results showed that the soundscape of Supino differs according to its cultural, habitual, and anthropological tendencies. In addition, the semantic analysis shows that the soundscape composition of the sound sources in the three zones varies by the change of time, sound composition and sources, topography, and settlement of the city.

Tensile Performance of Traditional and Modern Corner Joints in Wooden Structures
(Zagreb Univ, Fac Forestry, 2022) Atar, Musa; Gode, Fazli; Kucuktuvek, Mustafa; Akan, Asli Er; Ormecioglu, Hilal Tugba; Keskin, Hakan; 154406; Mimarlık
Corner joints are critical points of wooden structures not only in furniture construction but also in traditional wooden architecture, especially in constructions without nails. This study was performed to determine the effects of particular factors such as the axis of assembly, types of material, and adhesive on the tensile performance of various modern and traditional types of wooden corner joints. For this purpose, various corner joint specimens were prepared with three different wooden materials: Scots pine (Pinus sylvestris Lipsky) wood, Lombardy poplar (Populus nigra Lipsky) wood, and Medium Density Fibreboard (MDF) using two different adhesives: polyvinyl acetate (PVAc) and polyurethane (Desmodur-VTKA) glues; and five different wooden joint types: dowel, tongue-and-groove, half-blind dovetail, screw, and eccentric screw joints. Tensile performance tests, vertical and parallel to the axis of assembly, were carried out according to ASTM D 1037 guidelines. Experiments indicated that, while the tensile performance of MDF specimen connected with a screw and PVAc adhesive was the highest under loading parallel to the axis of assembly (4592 N); it was the lowest under loading parallel to the axis of assembly in MDF specimen connected with tongue-and-groove joint and PVAc adhesive (260 N), respectively. As a result, it may be advantageous to apply screwed joints in corners for high tensile strength in parallel to the axis of the assembly.

The Acoustic Characterization of Worship Ambiance and Speech Intelligibility in Wooden Hypostyle Structures: The Case of the Aslanhane Mosque
(Springer Singapore Pte Ltd, 2021) Kitapci, Kivanc; Celik Basok, Gulsah; 275153; 118348; İç Mimarlık
The challenge in the acoustics design of the traditional mosque is twofold. First, the interior atmosphere of the space should create a sacred feeling on the users' holistic and phenomenological spatial perception, which is generally recognized as a direct effect of increased reverberation time (T30) and low clarity (C80). Second, speech should be adequately intelligible, which requires a low T30 and high speech clarity, contradicting the initial concern of the sacred atmosphere. We hypothesize that in Islamic architecture, wooden hypostyle mosques may comply better with the reverberation time requirements of speech intelligibility, while maintaining the sacred feeling, due to their comparatively absorptive surface finishing materials and structural elements. The Aslanhane Mosque is a unique sacred structure within its era of construction, well-known with its wooden columns and ceiling. It is an important case for room acoustics analysis of such holy spaces. This study aimed to analyze the room acoustic measurement results of the Aslanhane Mosque, evaluating the intelligibility of speech and interpreting the sacred feeling created by reverberance, envelopment, and spaciousness, which are all crucial in such holy structures. It is revealed that although the Aslanhane Mosque's subjective rating for speech intelligibility is "good," the overall low volume of the mosque and the lack of surface reflections decrease the sacred sensation. Additionally, the intelligibility of speech is vulnerable to obstacles within the line of sight, such as load-bearing columns. Lastly, it was observed that the increase in T30 at low frequencies improved the sacred sensation, envelopment, and spaciousness, without any profound negative impact on the intelligibility of speech.
