Investigating the Relationship Between Volitional Strategies and Academic Achievement in a Flipped Learning Environment
(Fac Teacher Education, 2019) Seggie, Fatma Nevra; Kiziltepe, Zeynep; Birgili, Bengi
This study was conducted to determine whether there is a relationship between academic volitional strategies and academic achievement in a flipped learning environment. Academic achievement entails an environment where students exert self-discipline on classroom tasks. By using volitional strategies, learners can enhance engagement on academic tasks and complete assignments more efficiently. Undergraduate students enrolled in a teacher education programme at a higher education institution in Turkey participated in the research. Academic Volitional Strategies Inventory (AVSI), with alpha = .87 internal consistency, was applied to a group of students. The obtained data were explored through Pearson correlation. The results showed a statistically significant positive relationship between AVSI scores and academic achievements (r =.39, p=<.05). Hence, volitional skills and academic achievements act in concert in a teacher education programme.

Identification of Candidate Biomarkers and Pathways in Breast Cancer by Differential Network Analysis
(Inderscience Publishers, 2020) Mendi, Onur; Karahoca, Adem
Breast cancer is one of the most malignant cancers in women worldwide. The aim of the present study was to explore the underlying biological mechanisms of breast cancer. For this purpose, we propose a novel framework to reveal mechanisms that drive disease progression in breast cancer by combining prior knowledge in the literature with differential networking methodology. Our integration framework has resulted in the most important genes and interactions by allowing ranking the breast cancer-specific gene network. YY1, SMARCA5, FOXM1, STAT4 and PTTG1 were found to be the most important genes in breast cancer. Functional and pathway enrichment analyses identified numerous pathways that may play a critical role in disease progression. Considering the success of the comparison of the results with the literature, the systemic lupus erythematosus pathway may be a potential target of breast cancer.

Building a Community Through a Design Build Studio Program
(Springer international Publishing Ag, 2025) Inceoglu, Arda
This paper aims to provide a comprehensive and critical assessment of the outcomes stemming from a Design-Build program, a pedagogical approach widely adopted by educational institutions worldwide. These programs are instrumental in equipping students with vital practical skills, often unattainable within the confines of a conventional studio environment. While the objectives of this program align with those of similar initiatives in various educational institutions, an examination reveals an unexpected and substantial outcome. Beyond its primary goals, the Design-Build program has played an integral role in instilling a culture of collaboration and camaraderie within the school, thereby significantly contributing to the overall success of its architectural education. All stages of the program consist of collaborative processes, instilling from an early age the importance of working together by helping each other than individual competition.
Parameters Effects Study on Pulse Laser for the Generation of Surface Acoustic Waves in Human Skin Detection Applications
(2015) Chen, Kun; Wu, Sen; Li, Yanning; Li, Tingting; Fu, Xing; Dorantes-Gonzalez, Dante Jorge
Laser-induced Surface Acoustic Waves (LSAWs) has been promisingly and widely used in recent years due to its rapid, high accuracy and non-contact evaluation potential of layered and thin film materials. For now, researchers have applied this technology on the characterization of materials' physical parameters, like Young's Modulus, density, and Poisson's ratio; or mechanical changes such as surface cracks and skin feature like a melanoma. While so far, little research has been done on providing practical guidelines on pulse laser parameters to best generate SAWs. In this paper finite element simulations of the thermos-elastic process based on human skin model for the generation of LSAWs were conducted to give the effects of pulse laser parameters have on the generated SAWs. And recommendations on the parameters to generate strong SAWs for detection and surface characterization without cause any damage to skin are given.

Compaction and Shear Strength Behavior of Fresh and Aged Basic Oxygen Furnace (bof) Steel Slag
(2016) Yıldırım, İrem Zeynep; Prezzi, Monica
Use of industrial by-products in geotechnical engineering projects, such as in the construction of highway embankments, is advantageous because large volumes of these materials can be utilized. Basic oxygen furnace (BOF) steel slag is one of these industrial by-products. This paper provides a brief background on the characteristics of BOF steel slag and presents the results of a series of laboratory tests (grain-size analysis, maximum and minimum dry density, compaction, large-scale direct shear tests (LDS) and isotropically consolidated-drained triaxial compression (CID TX) performed on fresh and aged BOF steel slag generated from an Indiana steel plant. BOF steel slag samples from three different batches of production were tested, which allowed an evaluation of both aging processes and the effect of changes in gradation on the mechanical properties. The BOF steel slag tested in this study contained sand-size particles with varying percentages of gravel-and silt-size fractions. The moisture-density relationships for BOF steel slag were irregular with two peaks. Based on the LDS and CID TX test results, the BOF steel slag exhibited superior strength and stiffness characteristics than conventional geo-materials. The mechanical properties of fresh and aged BOF steel slag are discussed in the context of its use in geotechnical applications.
Free(?) Space at the 2018 Venice Biennale
(Intellect Books, 2019) Yücel, Şebnem
In his article ‘Out of Site/In Plain View: On the Origins and Actuality of the Architecture Exhibition’, architectural historian and curator Barry Bergdoll starts by asking the obvious question: ‘What does it mean to exhibit architecture? Isn’t architecture, once it is built, always already on display?’1 Despite always being on display, however, architecture escapes being exhibited. Because we cannot exhibit architecture in the way an artist can exhibit a painting or a sculpture.

An Overview on the Structural Monitoring, Assessment and Retrofitting of Historical Structures With a Focus on 13th Century Monuments
(Springer international Publishing Ag, 2024) Ilki, Alper; Inci, Pinar; Halici, Omer F.; Demir, Cem; Comert, Mustafa; Kuran, Fikret
Monumental historical structures affirm natural and cultural identity and hence they should be transmitted to future generations. The protection and preservation of these structures against aging and natural hazards, particularly seismic actions, requires a comprehensive approach including diagnosis of the present condition of the structure and enhancement of structural capacity for disaster mitigation, if necessary. It is obvious that due to their historical values, any attempt towards the preservation of the monumental historical structures must be carried out with respect to the principles of integrity and authenticity. In this study, the structural performance assessment procedures, implementation of structural health monitoring systems and seismic strengthening strategies are discussed and described with reference to 13th-century monumental historical structures in Turkiye. The structural engineering aspects of recent activities for the restoration and preservation of the Great Mosque and Hospital of Divrigi (a world heritage listed structure) and Sivas Ulu Cami (Mosque) Minaret are briefly presented. In light of the structural analysis and monitoring results, recommendations for interventions to these monumental structures are outlined.

Effect of Boron Addition to Steel on Mechanical Properties
(Springer Science and Business Media Deutschland GmbH, 2025) Özmen, Levent; Cakici, Mehmet; Yucel, Onuralp
In the production of qualified steel, if 5–30 ppm boron is present in the product, the hardenability of the steel increases significantly by the case hardening process. This small amount of boron content reduces the austenite grain size (by preventing grain growth) and increases the matrix hardness through the precipitates formed.With the addition of boron, it is possible to obtain the desired hardness depth due to the cementation applied especially in gear parts. This result obtained in boron steels is similar to Cr, Mn, Mo, Ni, etc., which are used in conditions where boron is not used. In other words, the use of boron as a microalloying element also provides cost savings. In this study, the parameters affecting the hardenability of steel by boron addition amounts in steel production using ferroboron were investigated on the basis of chemical content, metallographic structure, and mechanical properties. © The Minerals, Metals & Materials Society 2025.
Study of Tuned Mass Damper for Attenuating Skyscraper Oscillations Through Project-Based Learning
(Filodiritto Publisher, 2019) Şengül, Özden; Dorantes-Gonzalez, Dante Jorge
The intention of the project was to introduce a complex real-life engineering problem in an easy manner to sophomore students, namely, the topic of a tuned mass damper (TMD). Even though TMD is a multiple-degree-of-freedom vibration problem seen only in advanced university courses, the phenomenon of earthquake effects on buildings is easy to understand. In order to ease the complexity, the multi-degree-of-freedom mathematical problem was converted into a single degree of freedom, such as the behavior of a vertical single-mass cantilever beam. Through a do-it-yourself project to be done in home conditions, students are introduced to the topic of mechanical vibrations via seismic action on tall buildings. Two sections of the "Engineering Mechanics: Dynamics" course, with an overall number of 58 students, participated in the project. The project develops critical thinking and inquiry skills by designing and constructing the physical prototype of a building-like structure and its corresponding tuned mass damper; conducting an experiment under certain restrictions to test the stabilizing effect of the damper after an initial displacement; learning a proper software application to graph and measure underdamped oscillations; calculating corresponding vibration parameters; as well as analyzing and discussing experimental results. Students approach the problem of mass-damper tuning by means of trial and error, an on-purpose strategy to add fun and gambling to the process, to enthusiastically compete for the best performance in terms of efficiency of attenuation. Data were collected from direct observation, surveys, reports and presentations. The results showed that students positively and enthusiastically responded at all project stages and with a better understanding of the phenomenon and engagement in comparison with previous students of the same course without project. The impact of the project on students’ engagement and implications for engineering education are discussed.

The Dividing of the Sphere in Domes of Medieval Anatolia
(Springer Verlag, 2019) Özgan, Sibel Yasemin; Özkar, Mine
The stylistic language of art and architecture in medieval Anatolia largely consists of geometric features with various levels of mathematical complexity. Whereas the two-dimensional graphic designs employ certain geometric relations and rules, theirmaking, in three-dimensional space, relies on the spatial material qualities and the overall architectural form more than just visual transformations. For understanding how their architectonic harmony was implemented, it is crucial to consider not onlythe geometric design but also other parameters such as the surface geometry, the physical properties of the material, and the crafting technique. Under the patronage of Seljuks in Anatolia, the rigorous application of the decoration program on historicalbuildings manifests a collaboration coordinated by a master builder between mathematicians, designers, and craftsmen. Geometric patterns were applied to all kinds of building surfaces. Dome decorations particularly addressed challenges ofbuilding with spherical geometry. We investigate the historical ways to construct continuous patterns on dome surfaces and how each simultaneously handles aspects of geometrical calculation, the design, and construction processes.

Eaf Ladle Steel Slag as a Geo-Material: Compaction and Shear Strength Characteristics
(2018) Yıldırım, İrem Zeynep; Prezzi, Monica
The numerous issues associated with the excess steel slag that is disposed of in landfills every year can be reduced by using it as a geo-material. This paper provides the results of laboratory tests (i.e., sieve, hydrometer, specific gravity, compaction, compaction-particle degradation, and large-scale direct shear with a box size of 30.5 x 30.5 x 20 cm) performed on electric-arc-furnace ladle [EAF(L)] steel slag from a mini-mill in Indiana. Based on standard proctor test results, the maximum dry unit weight values of the EAF(L) steel slag were in the 16.8-to-20 kN/m(3) range at the optimum moisture contents of 11-13%. The results of the large-scale direct shear tests performed on EAF(L) steel slag, compacted at 95-100% relative compaction and sheared with normal stress ranging from 50 to 300 kPa, showed that it has excellent frictional characteristics, with friction angles between 40 and 45 degrees. Based on the results from this study, due to its shear strength characteristics, EAF(L) steel slag has the potential to be utilized as a geo-material to improve the shear strength of various marginal soils.

Near-Fault Earthquake Ground Motion and Seismic Isolation Design
(Springer International Publishing Ag, 2023) Harmandar, Ebru; Erdik, Mustafa; Demircioglu-Tumsa, Mine B.; Şadan, Bahadır; Tuzun, Cuneyt; Ulker, Omer
Seismic isolation is one of the most reliable passive structural control techniques with adequately established standards for the earthquake protection of structures from earthquakes. However, it has been shown that the seismic isolation systems may not function the best for the near-fault ground motions, since in the proximity of a capable fault, the ground motions are significantly affected by the rupture mechanism and may generate high demands on the isolation system and the structure. In fact, several earthquake resistant design codes state that the seismically isolated structures located at near-fault sites should be designed by considering larger seismic demands than the demand on structures at far-field sites. When the fault ruptures in forward direction to the site most of the seismic energy arrives in coherent long-period ground velocity pulses. The ground-motion prediction equations (GMPEs) typically cannot account for such effects with limited distance metrics and lack adequate data at large magnitudes and near distances. For the reliable earthquake design of the isolated structure in near fault conditions that meets the performance objectives, the 3D design basis ground motion(s) need to be appropriately assessed. Measures in the design of the isolation system, such as modifications in the stiffness and damping characteristics, as well as in the limitation of vertical effects are needed. The behavior of the base-isolated buildings under near-fault (NF) ground motions with fling-step and forward-directivity characteristics are investigated with a rational assessment of design-basis near-fault ground motion, are investigated in a parametric format. The parametric study includes several variables, including the structural system flexibility; number of stories; isolation system characteristic (yield) strength, and the isolation periods related to the post-elastic stiffness. Furthermore, the effect of additional damping by viscous dampers were tested for some selected cases. Important findings observed from the parametric performance results and the overall conclusions of the study are provided.
Influence of Local Soil Conditions on Damages in Kahramanmaras during the 2023 Turkey Earthquake
(Springer Science and Business Media Deutschland GmbH, 2025) Milev, Nikolay; Kiyota, Takashi; Tobita, Tetsuo; Briones, Juan; Briones, Othon; Cinicioglu, Ozer; Torisu, Seda
The 2023 Turkey-Syria earthquake affected an area of 99000 km2 on Turkish side where two million people were left without home. The PGA values which have been recorded by various stations show values as high as 1.2g as well as relatively spectacular maximum vertical component (PGV). The focus of the paper is to focus on a noticeable phenomenon in the city of Kahramanmaras where, on one hand, almost all buildings in the historical centre have either collapsed or been severely damaged by the two earthquakes (Pazarcik at 4:17 AM and Elbistan at 1:24 PM, respectively) of February 6th 2023, whereas, on the other hand, structures in the surrounding areas have significantly less damage. Moreover, it is evident from seismic stations’ recordings that impact (in terms of PGA, acceleration and velocity time histories) of first major shock (M7.7 Pazarcik) is higher than the one of the second major shock (M7.6 Elbistan) at similar magnitude and comparable distance to the epicenter. For the sake of investigating further the influence of local soil conditions as possible reason for the observed events shear wave velocity and soil deposit fundamental frequency have been measured in two spots – first, where multiple collapsed structures were detected and second, a neighbouring area with mostly standing buildings. Results indicate that the on-site measurement of only S-waves might lead to wrong assumptions in terms of microseismical zonation and further considerations shall be accounted. Furthermore, some comments and preliminary assumptions regarding seismic motion amplification effects have been presented in the study. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Understanding the Psychological and Financial Correlates for Consumer Credit Use;
(Sosyoekonomi Society, 2024) Ertuğrul, Seyit; Sayar, Alperen; Şahin, Türkay; Çakar,Tuna
This study investigated the behavioural and cognitive predictors of consumer credit usage to develop a behavioural credit risk assessment procedure for a factoring company. Participants completed surveys measuring personality traits, self-esteem, material and monetary values, compulsive and impulsive buying tendencies, self-control, and impulsiveness. Financial surveys also assessed financial literacy and knowledge of financial concepts. The results indicated that extraversion, conscientiousness, emotional stability, and experiential self-control were significant predictors of consumer credit usage. These findings suggest that a finance company can use these personality traits and financial characteristics to develop a more accurate and effective credit risk assessment procedure, such as psychometric tests. © 2024, Sosyoekonomi Society.

Exploring the Drivers of Green Purchase Behaviour: the Moderating Roles of Perceived Expensiveness and Green Scepticism
(inderscience Enterprises Ltd, 2024) Aydın, Kenan; Altan, Meral Uzunöz; Köse, Şirin Gizem; Çizer, Ece Özer
This research aims to investigate factors affecting green consumption behaviour by utilising theory of planned behaviour and extends the theory by integrating environmental attitude, perceived expensiveness, and green scepticism variables. The results show that environmental attitude, attitude towards purchasing green products, subjective norms, and perceived behaviour control variables determine green product consumption. The study also presents the partial mediator role of attitude towards buying green products in the relationship between environmental attitude and green product purchase behaviour. Furthermore, perceived expensiveness and green scepticism have negative moderating roles in the relationship between attitudes toward purchasing green products and green purchase behaviour.

AI-Driven Digital Soil Mapping: Leveraging Generative AI, Ensemble Learning and Geospatial Technologies for Data-Scarce Regions
(Springer Science and Business Media Deutschland GmbH, 2025) Drias, Yassine; Drias, Habiba; Belkadi, Widad Hassina; Cakar, Tuna; Abdelhamid, Zakaria; Bensemmane, Riad Yacine
This study presents a methodology for generating highresolution digital soil maps by integrating artificial intelligence (AI) with geospatial technologies. The research begins with comprehensive data collection and the extraction of relevant soil properties with the help of generative AI. To improve predictive accuracy, ensemble learning algorithms were employed due to their ability to capture complex relationships within soil characteristics. Additionally, a structured preprocessing pipeline was developed to refine and standardize the collected soil data, ensuring its suitability for modeling. The model's performance was evaluated using spatial cross-validation techniques to identify the most effective predictive approach. To validate the proposed methodology, experiments were conducted in northern Algeria, a region characterized by diverse landscapes ranging from arid zones to fertile plains. The results demonstrate the potential of AI-driven approaches to enhance soil mapping, particularly in regions where high-quality and up-to-date soil data are limited. This study underscores the efficacy of AI and geospatial technologies in advancing precision agriculture and land management.
