Analyzing Cost Efficiency and Project Scope in Post-Disaster Housing: Reconstruction Cases of Toki in Türkiye
(MDPI, 2025) Geylani, Ozlem
The Mass Housing Administration of T & uuml;rkiye (TOKI) operates as the primary public organization responsible for delivering extensive affordable housing throughout T & uuml;rkiye while ensuring disaster resilience. The recent decades of earthquakes and environmental hazards in T & uuml;rkiye have necessitated extensive post-disaster reconstruction initiatives nationwide. In response, TOKI has completed numerous disaster housing projects across the country through an integrated infrastructure framework supporting community recovery. This study presents an extensive statistical evaluation of 664 disaster housing projects constructed by TOKI across 40 provinces. Specifically, a quantitative analysis is conducted on 434 disaster housing projects for which detailed financial data are available. This research examines differences in construction costs between urban mass housing developments and rural village settlements, particularly focusing on the integration of functional structures such as schools, mosques, commercial units, and barns. Although mass housing projects require significantly larger total budgets due to their extensive scale, statistical analysis reveals no significant difference in per-unit construction costs between mass housing and village housing projects. Regression analysis indicates that incorporating barns increased per-unit construction costs, while the presence of schools and mosques significantly decreases these expenses. The findings of this research provide critical insights into the economic and functional factors influencing disaster housing reconstruction in T & uuml;rkiye and offer practical recommendations for improved planning, resource management, and community reconstruction based on an evaluation of functional structures.
Applicability of a Digitalization Model Based on Augmented Reality for Building Construction Education in Architecture
(Emerald Group Publishing Ltd, 2023) Guray, Tayibe Seyman; Kismet, Burcu
Purpose The purpose of this paper is to introduce a digitalization model (DM) for building construction courses in architectural education as a response to the recent emerging technologies in the era of digital transformations. This DM is developed and applied through augmented reality (AR) technologies to boost perception, understandings and ability to solve building construction details. Design/methodology/approach Based on a thorough review of recent technologies like AR, virtual reality (VR), building information modelling (BIM) and their applications in architectural education, the methodology involves the generation of a model, its application and evaluation. The model is based on the integration of BIM and AR which is applied into a third year "Building Construction Project" course. Each student has designed a residential building and accordingly prepared the construction drawings by adapting the DM. An online survey -based on Technology Acceptance Model - is conducted to evaluate the DM by quantitative data analysis from SPSS and Excel. Findings The key findings of the study include the following items: determination of the proper digital tools, the definition of the steps and workflow based on the building project phases to develop construction drawings and define precise details effectively. By the help of this, the DM is generated and applied. According to the survey and results, the DM which involves BIM-based AR is considered as beneficial, highly motivating and providing better perception on construction details. Originality/value Implication of AR/VR technologies is frequently seen in design studios, whereas building construction courses state its traditional approach. However, there is a huge potential in the digitalization of building construction education by increasing the perception of students together with the increased level of communication. The study aims to close the gap of digitalization by proposing a DM, which brings a systematic approach considering each phase of building construction project as conceptual, schematic, design development and construction documents by using BIM integrated AR. Moreover, the novel model specifically brings a new approach by generation of QR codes for construction details to embed videos or simulations into the two-dimensional drawing sheets. Furthermore, the DM proposes a new approach to satisfy emerging needs and requirements of the Architecture Engineering Construction industry.

Key implementation steps include upgrading energy systems, deploying IoT sensors, creating digital replicas of airport infrastructure, and establishing regulatory and stakeholder collaboration frameworks. This research contributes a replicable framework for airports worldwide, bridging theoretical models with actionable solutions.
Can Commercial Buildings Cope with Australian Bushfires? An IAQ Analysis
(Ubiquity Press Ltd, 2021) Brambilla, Arianna; Candido, Christhina; Sangiorgio, Marco filippo; Gocer, Ozgur; Gocer, Kenan
The Australian 2019/20 summer witnessed an extraordinary bushfire season characterised by unprecedented duration, geographical reach and impact. The aftermath of the bushfires includes increased health-related implications on people due to short and long exposure to poor air quality. The current advice from the Australian authorities in such events is to remain indoors, as it was assumed indoor air quality (IAQ) is healthy. This paper examined that assumption and presents the case study of an office building in Canberra subjected to the 2019/20 bushfires, responding to the need of understanding the ability of air-conditioning buildings to cope with such unprecedented and extreme weather events. Measured data for indoor concentration of CO2, PM10 and PM2.5 recorded a prolonged period of concerning levels, as well as extreme concentration peaks. This poses a significant risk to the occupants' health. The values showed peaks up to 12 times higher for PM10 and 24 times higher for PM2.5 than the recommended critical thresholds. The infiltration factor and protection performance analysis suggest that old filtering systems and low airtightness levels are not optimal in protecting the indoor environment from outdoor air pollutants.
Cd Dopant Effect on Structural and Optoelectronic Properties of TiO2 Solar Detectors
(Springer, 2021) Ilhan, Mustafa; Koc, Mumin Mehmet; Coskun, Burhan; Erkovan, Mustafa; Yakuphanoglu, Fahrettin
Al/n-Si/Ti1-xO2CdxO/Al photodiodes were produced using sol-gel and spin coating methods where CdO dopant was applied on different concentrations (x = 0.0; x = 0.01; x = 0.05; x = 0.10). Cd dopant effect upon structural, optical, photodiode and electrical properties was assessed. Scanning electron microscope and energy-dispersive spectra were used in the structural investigation. Optic properties were assessed using UV-Vis spectroscopy and bandgap energies of the photodiodes were calculated which were found to be between 3.25 and 3.36 eV. Increased bandgap energy was observed with increased CdO doping rate. Photodiode properties were assessed under varying daylight illuminations. Barrier height, ideality factor, dark current, linear dynamic rate, photosensitivity, photoresponsivity of the photodiodes were calculated. Electrical properties of the Al/n-Si/Ti1-xO2CdxO/Al photodiodes were calculated where conductance-voltage and capacitance-voltage plots were obtained. Corrective conductance-voltage and corrective capacitance-voltage graphs confirm that the electrical properties of the photodiodes depend on AC signal frequency. Frequency-dependent electrical characteristics were attributed to the density of interface states which were found to be between 10(11) and 10(12). Decreased density of interface state was found for increased AC signal frequency.
Changes in Anthocyanin Pigments, Trans-Resveratrol, and Colorimetric Characteristics of Fondillón Wine and Other “Monastrell” Wines During the Aging Period
(Springer Science and Business Media Deutschland GmbH, 2023) Uysal, R.S.; Issa-Issa, H.; Esther, E.; Carbonell-Barrachina, A.A.
The studied red wines, which are Fondillón, reserva, crianza, and young, are prepared from exclusive “Monastrell” grapes, and protected under the Alicante Denomination of Origin (Alicante, Spain). The objectives of the present study were (i) to show the effect of aging period on the amount of anthocyanin pigments, trans-resveratrol, and the colorimetric characteristics (color intensity, color density, and tonality) of Fondillón and other Monastrell wines (young, crianza, and reserva) which have different aging periods, and (ii) to propose a new traceability method for the determination of the Fondillón originality. Identification of anthocyanin compounds and determination of trans-resveratrol content were performed using LC–MS/MS. Correlation analysis was performed among anthocyanin compounds and color parameters. A sharp decrease in the anthocyanins content was observed in Fondillón wine. Besides, statistically significant changes were found in all colorimetric parameters between young and Fondillón samples. A significant change from red hue to brick red/yellow hue was observed between the colors of young and Fondillón wines, respectively. A significant decrease in the content of trans-resveratrol was also observed as a result of the aging period of these “Monastrell” wines. In this study, anthocyanin compounds of Fondillón wine were identified for the first time and their effects on the colorimetric parameters of the wine were revealed. Consequently, the authenticity of Fondillón wines can be determined by monitoring of anthocyanin compounds and trans-resveratrol. © 2023, The Author(s).
Charge and Thermal Transport Properties of Undoped and Doped T L + (IN3 + X22−)− Ternary Dichalcogenides with a Reduced Dimensionality: Perfect Candidates for Thermoelectric Applications in the Mid-Temperature Region
(Institute of Physics, 2025) Yavuz, M.F.; Gökçe, S.; Gür, E.S.; Mammadov, T.G.; Najafov, A.I.; Salehli, F.; Akşit, M.
The present work focuses on a comprehensive investigation of charge and thermal transport properties of thallium-indium-based ternary dichalcogenides with a common chemical formula of T l + ( I n 3 + X 2 2 − ) − where X denotes tellurium, selenium or sulfur atoms. Two compounds in the one-dimensional chain form, including pristine TlInSe2 and Fe-doped TlInTe2 as well as a hybrid material constructed from the two-dimensional TlInS2 layered semiconductor diluted with TlFeS2 at % 0.7, have been successfully grown using the Bridgman-Stockbarger technique. X-ray powder diffraction, scanning electron microscopy and energy-dispersive x-ray spectroscopy measurements were performed to characterize the local structure and chemical composition features of all prepared compounds. A strong anisotropy in the charge-carrier transport properties of the samples was observed from dc - and ac - electrical conductivity measurements made in directions parallel and perpendicular to the layers/chains. This is a fundamental property for realizing high thermoelectric performance in semiconducting materials. As a result, extremely large Seebeck coefficients were revealed upon experimental investigations of the thermoelectric properties of T l + ( I n 3 + X 2 2 − ) − samples over a wide temperature range between ∼100 K and ∼800 K. The first-principles density functional theory (DFT) and Boltzmann transport equations were employed to investigate the thermal transport properties of the compounds studied at the atomic scale. A specific interaction between the thallium cation and the sulfur anion was observed in the DFT computation scheme. The developed interaction (more electrostatic than a much weaker van der Waals one) enhances the charge carrier effective mass via flattening of the electronic bands near the band edges and this can give a new path towards Seebeck coefficient enhancement in the traditional mid-temperature range. © 2024 IOP Publishing Ltd.

Comment on “Charged Zipoy-Voorhees Metric in String Theory”
(Academic Press Inc., 2025) Gürtuğ, O.; Halilsoy, M.; Mangut, M.
In a recent paper by Yunusov et al. (2025) it is claimed that the charged Zipoy–Voorhees (ZV) metric found in a paper by Gurtug et al. (2022) does not satisfy the Einstein–Maxwell (EM) equations. It is our aim in this comment to show that this claim is invalid. Nevertheless, their stringy EM extension of the ZV metric remains valid. © 2025 Elsevier Inc.
Comparing Cognitive Behavioral Therapy and Ericksonian Hypnotherapy for Obsessive–Compulsive Disorder: A Randomized Controlled Trial
(Routledge, 2026) Çınaroğlu M.; Yılmazer E.; Odabaşı C.; Ülker S.V.; Tan S.; Hızlı Sayar G.
Obsessive–Compulsive Disorder (OCD) is a chronic condition that often responds well to Cognitive Behavioral Therapy (CBT), though many patients fail to achieve full remission. Ericksonian Hypnotherapy (EH) has been proposed as a promising alternative. This randomized controlled trial compared the efficacy of CBT and EH against a waitlist control in 99 adults with OCD. Participants received 12 weekly online therapy sessions. Outcomes were assessed at baseline, mid-treatment, and post-treatment using the Padua Inventory-Revised, Yale–Brown Obsessive Compulsive Scale–Self-Report (Y-BOCS-SR), and Beck Anxiety Inventory (BAI). Both CBT and EH led to large, statistically and clinically significant reductions in OCD symptoms compared to waitlist. CBT was more effective for compulsive behaviors such as washing, while EH produced greater reductions in obsessive rumination and general anxiety. No serious adverse events occurred. These findings suggest that EH is a viable and comparably effective treatment to CBT, with distinct therapeutic benefits. EH may offer a particularly useful option for patients with obsession-dominant symptom profiles or comorbid anxiety. © 2026 International Journal of Clinical and Experimental Hypnosis.
Comparison of Domino Transplantation with Two-Way Paired Exchange and Normal Transplantation: Acute Rejection, Surgical Complications, and 5-Year Survival Outcomes
(Springer, 2025) Huseynov, Amil; Cicek, Sevim Nuran Kuslu
Background Domino kidney paired donation and Two-Way Paired Exchange have emerged as vital strategies to expand the donor pool in renal transplantation, especially for patients facing ABO or HLA incompatibilities. Despite their potential benefits, concerns remain regarding immunological risks, infectious complications, and long-term graft survival. Methods In this retrospective cohort study conducted at Medicana Transplant Center, 980 adult kidney transplant recipients were categorized into three groups: Domino (n = 144), Two-Way Paired Exchange (n = 350), and Normal Transplant (n = 486). Baseline characteristics, acute rejection rates, and surgical or infectious complications were collected, alongside data on 1-year and 5-year patient and graft survival. Statistical analysis included Kaplan-Meier survival curves and Cox proportional hazards modeling for independent predictors of graft outcomes. Results The Domino group had the highest 1-year acute rejection rate (17.4%) compared to Two-Way Paired Exchange (4.3%) and Normal Transplant (3.7%), yet 1-year graft survival rates remained comparable (92%, 95%, and 96%, respectively; p = 0.271). Infectious complications were more frequent in the Domino group (25%) than in others (p < 0.01). Extended follow-up to 5 years indicated no statistically significant difference in overall graft or patient survival among the three groups (log-rank p = 0.197), despite a trend toward lower 5-year graft survival in the Domino group. Donor-specific antibodies and higher HLA mismatches independently predicted acute rejection. Conclusions Domino transplantation, while associated with higher immunologic challenges, achieves acceptable short-term and 5-year outcomes akin to Two-Way Paired Exchange and Normal Transplant. Careful immunosuppressive strategies, vigilant monitoring, and collaborative protocols are integral for optimizing long-term success in high-risk transplant scenarios.

Desire and Absence in Rimini Protokoll's Conference of the Absent: A Lacanian Analysis of Audience Interviews
(John Wiley and Sons Ltd, 2026) Akıncı Ö.; Sümerkan H.H.
This paper explores the Conference of the Absent experience, a participatory theater piece produced by Rimini Protokoll, through a Lacanian psychoanalytic perspective. Drawing on semi-structured interviews with audience members who participated in the performance, it seeks to analyze the anxieties and resistances around performing, as well as how these experiences are retrospectively narrated and made sense of. Conference of the Absent is considered as a reconfiguration of the spectator-performer relation in a manner analogous to processes of subject formation in Lacanian psychoanalysis. The paper, thus, discusses how the performance destabilizes scopic mastery, repositions the voice as the central medium of subjectivation and situates the participants in a new system of meaning. Drawing from the audience interviews and analysis of the theatrical design, it is argued that the audience's engagement is less an act of personal agency than a pre-orchestrated response conditioned by the performance's dramaturgical design. This paper contributes to theater audience research by offering psychoanalytical theory as a methodological tool in understanding the workings of spectatorship in a participatory theater setting. © 2026 John Wiley & Sons Ltd.
Developing a Building-Scale Circularity Indicator Through Fuzzy Analytical Hierarchy Process and Gini Index-Based Circularity Calculation Methods
(Taylor & Francis Ltd, 2025) Kismet, Burcu; Colakoglu, Meryem Birgul
Circular economy (CE) aims to achieve sustainable development by optimizing resource efficiency through innovative system designs. The built environment plays a crucial role in this transition, yet the absence of standardized indicators hinders effective circularity assessment. This study introduces a structured building-scale circularity indicator (BuCI) to support industry and academia in evaluating buildings' circularity levels and facilitating the shift towards a circular built environment. Based on a thorough review of CE, the methodology involves the generation of a model, its implementation on a selected case study and evaluation. The proposed model integrates the shearing layer and building lifecycle concepts to establish a measurement framework with defined criteria and key performance indicators. Fuzzy analytical hierarchy process and Gini index are used to formulate circularity calculation. Then, the BuCI is implemented on three different case studies, two steel and one reinforced concrete buildings. CS1 and CS2 reached 60% circularity level, thanks to the material advantages and certain design principles such as modularity, disassembly and flexibility, whereas CS3 calculated as 31.05% circular due to material and design decisions. The study contributes to the field by introducing a novel indicator for the industry, academia and authorities to accelerate the circular transition. For future studies, it is suggested to integrate cost and cultural heritage related criteria.

(Elsevier, 2025) Mizrak, Filiz; Mizrak, Kagan Cenk; Akkartal, Gonca Reyhan
The purpose of this study is to develop a comprehensive decision-making framework that airlines can use to strategically select new destinations, demonstrated here with a case application for Turkish Airlines. Addressing the complexities of route expansion, the study integrates the Entropy weighting method with the 2-Tuple Linguistic T-Spherical Fuzzy Decision by Opinion Score Method (2TLTS-FDOSM) to evaluate potential destinations across critical criteria, including market demand, economic impact, and regulatory environment. Data were collected from industry reports, expert evaluations, and publicly available aviation metrics to support a thorough and adaptable analysis. Findings from the Turkish Airlines case reveal San Antonio, TX (SAT), Portland, OR (PDX), and Nashville, TN (BNA) as top-ranked destinations, each offering distinct economic and operational benefits. This study contributes to aviation management literature by presenting a versatile, data-driven framework that can guide route selection for carriers in competitive markets. The framework's ability to balance quantitative and qualitative insights underscores its potential for broader application in network planning, promoting sustainable growth within the aviation industry.
The Development and Validation of an Integrated Assessment of Irrational Beliefs Concerning Basic Psychological Needs: The Rational Emotive Self-Determination Scale for Workers
(Frontiers Media Sa, 2025) Artiran, Murat; Tinaz, Pinar; Simsek, Omer Faruk; Miller, Anthony; Vione, Katia Correa; Turner, Martin James
Introduction Recently a new approach to understanding human behaviour has emerged that integrates rational emotive behaviour therapy (REBT) from the cognitive behavioural tradition, and self-determination theory (SDT) from the humanistic tradition. In the current study, we develop a psychometric that conceptualizes this new approach in organisational settings; the rational emotive self-determination scale for work (RESD-W). The RESD-W assesses respondents' irrational beliefs (from REBT) concerning the basic psychological needs (from SDT), namely perceptions of autonomy, competence, and relatedness within their work life. The RESD-W builds on initial validations of the RESD in adolescent populations (RESD-A).Methods In the current paper, the psychometric properties of the 16-item RESD-W were examined across five studies, in which the factor structure, the reliability of the scale, and construct and criterion-oriented validity of the RESD-W were assessed.Results Analyses confirmed theoretical expectations and yielded good psychometric properties. Scores in the RESD-W were associated with anxiety and depression, and negative emotions in the workplace.Discussion The results are discussed regarding practice, highlighting that work related psychological wellbeing may be predicated on the integration of irrational beliefs and basic psychological needs.
Differences in Occupants' Satisfaction and Perceived Productivity in High- and Low-Performance Offices
(MDPI, 2019) Gocer, Ozgur; Candido, Christhina; Thomas, Leena; Gocer, Kenan
This paper reports the results from a dataset comprising 9794 post-occupancy evaluation (POE) surveys from 77 Australian open-plan offices. This paper specifically focuses on a sub-set of 20 offices (n = 2133), identified from ranking 10 offices each, with the least (n = 1063) and highest (n = 1070) satisfaction scores, respectively. The satisfaction scores were evaluated on the basis of seven factors (i.e., building/office aesthetics and quality, thermal comfort and indoor air quality, noise distraction and privacy, personal control, connection to outdoor environment, maintenance and visual comfort, and individual space). Using the POE survey data from 20 offices, regression analyses and two-way ANOVA tests were carried out to understand the differences in occupants' satisfaction and perceived productivity arising from open-plan offices. According to the statistically significant regression analyses results, it was identified that building/office aesthetics and quality (beta = 0.55, p < 0.001) and noise distraction and privacy (beta = 0.33, p < 0.001) were the two strongest predictors contributing perceived productivity in low-performance offices. Two-way ANOVA test results for the 10 high-performance offices indicate that the perceived productivity was strongly associated with the office's physical configuration, the employees' working experience, and the working hours at that office.

This research addresses a critical gap by focusing on the human dimensions of cybersecurity management and offers practical recommendations for simplifying protocols and fostering resilience. The study provides actionable insights for organizations operating under stringent cybersecurity requirements, enabling them to enhance employee satisfaction and performance.
Discriminant Analysis Using MRI Asymmetry Indices and Cognitive Scores of Women with Temporal Lobe Epilepsy or Schizophrenia
(Springer Science and Business Media Deutschland GmbH, 2024) Fırat, Z.; Er, F.; Noyan, H.; Ekinci, G.; Üçok, A.; Ulǔg, A.M.; Aktekin, B.
Purpose: This study aims to assess the diagnostic power of brain asymmetry indices and neuropsychological tests for differentiating mesial temporal lobe epilepsy (MTLE) and schizophrenia (SCZ). Methods: We studied a total of 39 women including 13 MTLE, 13 SCZ, and 13 healthy individuals (HC). A neuropsychological test battery (NPT) was administered and scored by an experienced neuropsychologist, and NeuroQuant (CorTechs Labs Inc., San Diego, California) software was used to calculate brain asymmetry indices (ASI) for 71 different anatomical regions of all participants based on their 3D T1 MR imaging scans. Results: Asymmetry indices measured from 10 regions showed statistically significant differences between the three groups. In this study, a multi-class linear discriminant analysis (LDA) model was built based on a total of fifteen variables composed of the most five significantly informative NPT scores and ten significant asymmetry indices, and the model achieved an accuracy of 87.2%. In pairwise classification, the accuracy for distinguishing MTLE from either SCZ or HC was 94.8%, while the accuracy for distinguishing SCZ from either MTLE or HC was 92.3%. Conclusion: The ability to differentiate MTLE from SCZ using neuroradiological and neuropsychological biomarkers, even within a limited patient cohort, could make a substantial contribution to research in larger patient groups using different machine learning techniques. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
Drivers and Barriers on Implementing XR Technologies in the Construction Industry in Turkey
(Taylor & Francis Ltd, 2024) Seyman-Guray, Tayibe; Kismet, Burcu
This study presents drivers and barriers on construction industry extended reality (XR) implementations in Turkey. It aims to investigate the current state and future directions of XR opportunities for architecture offices and construction companies in a developing country. A quantitative approach was employed which involves conducting a survey, performing statistical analyses, and verification of the hypotheses. The data were analyzed by SPSS and Excel using the frequency, mean score, standard deviation (SD), and one sample t-test. Thirty-three different companies participated in the survey with a return rate of 56.89%. The results were considered statistically significant since all the p-values were below 0.05. The findings revealed that even though 60% of the companies are not using XR, 60% companies have near future plans on implementing them. According to the results, XR was considered as beneficial and highly motivating for the near future, yet it needs to be widespread for companies to keep themselves abreast of information and communication technology trends. Finally, by considering the findings obtained from the results this study reaches a classification of drivers as 'increased efficiency: time-cost-quality' and 'increased communication and coordination' while barriers as 'technical limitations', 'high costs', and 'unqualified professional'.
Effect of Heat Treatment on Magnetic Properties of Nanocomposite Nd-Lean Nd7Fe73b20 Ribbons
(Springer, 2021) Caglar, Seyit; Kilicaslan, M. Fatih; Atasoy, Ahmet; Tiryaki, Hasan; Erkovan, Mustafa; Hong, Soon-jik
In this work, we explored the effect of heat treatment on high boron and Nd-lean content magnetic Nd7Fe73B20 nanocomposite materials via vibration sample magnetometer (VSM), X-ray diffraction, differential thermal analysis (DTA), and scanning electron microscope (SEM). The Scherer formula was employed to estimate the effect in the crystal size of the heat treatment on high boron and Nd-lean content magnetic Nd7Fe73B20 nanocomposite materials. We heat-treated samples in different conditions to obtain optimum magnetic properties. Our high-throughput fabrication strategy allows us to elucidate the possibility of obtaining Nd-lean nanocomposite NdFeB magnet in terms of the melt-spinning. We evaluated the influence of heat treatment on the Nd-lean NdFeB/alpha-Fe nanocomposite magnets produced by melt-spinning. Here, in the heat-treated ribbon at 750 degrees C for 30 min, we obtained a combination of coercivity of 450 Oe, a high-saturation magnetization of 232 emu/g in the heat-treated ribbon at 650 degrees C for 30 min, which surpasses most traditional nanocrystalline magnets based on Fe-Co and pricey. The results we present here are expected to serve as a guideline for designing new magnets for industrial applications.
