    Post-seismic structural assessment: advanced crack detection through complex feature extraction using pre-trained deep learning and machine learning integration

    Reis, Hatice Catal; Turk, Veysel; Ustuner, Mustafa; Kaya Yildiz, Cagla Melisa; Tatli, Ramazan

    Earthquakes can often cause significant damage to buildings. After an earthquake, experts/managers need to make quick and accurate damage assessments. Traditionally, manual analysis processes have been widely used in damage assessment studies. The fact that these methods are time-consuming and based on human observation leads to certain limitations in damage assessment studies. In recent years, artificial intelligence techniques such as deep learning and machine learning have frequently been preferred in damage detection studies, and significant success has been achieved. This study aimed to automatically detect cracks/damages in the buildings in Diyarbakir city after the February 6, 2023 Kahramanmaras, Turkey earthquake. Our experimental dataset was collected by the researchers and named Kahramanmaras-Diyarbakir Earthquake Building Crack Dataset (KDBECD-2023). The data set consists of four categories in terms of damage level: undamaged, slightly damaged, moderately damaged, and heavily damaged buildings. DenseNet201 deep learning architecture and popular machine learning algorithms, Support Vector Machine, Random Forest, Decision Tree, and K-Nearest Neighbors (KNN) were used to classify cracks at different damage levels. In the experimental phase, feature extraction was performed with the DenseNet201 architecture. In addition, dimensional reduction was applied with the Principal Component Analysis method to reduce the computational complexity of the proposed hybrid study. According to the experimental results, the DenseNet201-KNN hybrid model gave the most successful result with an accuracy value of 94.62%. The results of this study can make important contributions to decision makers and experts in detecting cracks and damages in buildings after an earthquake.

    Soil Amplification and Code Compliance: A Case Study of the 2023 Kahramanmaraş Earthquakes in Hayrullah Neighborhood

    Avcı, Eyübhan; Afacan, Kamil Bekir; Deveci, Emre; Uysal, Melih; Altundaş, Suna; Balcı, Mehmet Can

    In the earthquakes that occurred in the Pazarcık (Mw = 7.7) and Elbistan (Mw = 7.6) districts of Kahramanmaraş Province on 6 February 2023, many buildings collapsed in the Hayrullah neighborhood of the Onikişubat district. In this study, we investigated whether there was a soil amplification effect on the damage occurring in the Hayrullah neighborhood of the Onikişubat district of Kahramanmaraş Province. Firstly, borehole, SPT, MASW (multi-channel surface wave analysis), microtremor, electrical resistivity tomography (ERT), and vertical electrical sounding (VES) tests were carried out in the field to determine the engineering properties and behavior of soil. Laboratory tests were also conducted using samples obtained from bore holes and field tests. Then, an idealized soil profile was created using the laboratory and field test results, and site dynamic soil behavior analyses were performed on the extracted profile. According to The Turkish Building Code (TBC 2018), the earthquake level DD-2 design spectra of the project site were determined and the average design spectrum was created. Considering the seismicity of the project site and TBC (2018) criteria (according to site-specific faulting, distance, and average shear wave velocity), 11 earthquake ground motion sets were selected and harmonized with DD-2 spectra in short, medium, and long periods. Using scaled motions, the soil profile was excited with 22 different earthquake scenarios and the results were obtained for the equivalent and non-linear models. The analysis showed that the soft soil conditions in the area amplified ground shaking by up to 2.8 times, especially for longer periods (1.0–2.5 s). This level of amplification was consistent with the damage observed in mid- to high-rise buildings, highlighting the important role of local site effects in the structural losses seen during the Kahramanmaraş earthquakes.

    Long-term mechanical and physical behavior of rural concrete roads: A case study from Trabzon; [Kırsal beton yolların uzun vadeli mekanik ve fiziksel davranışı: Trabzon’dan bir vaka çalışması]

    Seferoğlu, Mehmet Tevfik; Lermioğlu, Fatma

    This study evaluates the long-term mechanical and physical performance of rural concrete pavements-defined as two-lane, unreinforced jointed plain concrete pavements constructed with a C25 mix design, an average slab thickness of 18–20 cm, serving low-to-moderate traffic volumes (<500 vehicles/day, <10% heavy vehicles), and built directly over compacted granular subgrade-using cylindrical core samples extracted from five neighborhoods in Trabzon, Türkiye: Çal, Gökçeler, Derecik, Çiğdemli, and Yolgören. Laboratory tests included compressive strength, splitting tensile strength, elastic modulus, capillary water absorption, and abrasion resistance. Yolgören exhibited the most severe deterioration, with a 34.84% loss in compressive strength, the lowest tensile strength, and the highest abrasion loss (0.088%), primarily attributed to poor drainage and heavy traffic. Derecik showed 22.18% strength loss and the lowest elastic modulus (14.9×103 MPa), likely due to weak subgrade and freeze-thaw cycles. Çal displayed moderate strength but had the highest capillarity coefficient and significant stiffness reduction (elastic modulus: 15.7×103 MPa), indicating high porosity and freeze-thaw damage. Çiğdemli performed best in surface durability, with the lowest abrasion loss (0.026%) and satisfactory elastic modulus. Gökçeler presented a rare case of strength gain (+0.85%) and retained acceptable stiffness, though minor surface wear (abrasion loss: 0.038%) was observed. These findings demonstrate that mix design alone does not guarantee long-term durability in rural pavements. Site-specific factors-such as curing effectiveness, drainage planning, subgrade preparation, and climate-must be considered in pavement design. A context-sensitive, performance-based approach is recommended for the sustainable development of rural road infrastructure.

    Influence of PGA/PGV ratio on the seismic performance of buildings with different slenderness ratios considering soil-structure interaction

    Araz, Onur

    In this study, the seismic performance of buildings equipped with tuned mass damper (TMD) having different slenderness ratios, subjected to ground motions with varying a wide range of PGA/PGV ratios is investigated, considering soil-structure interaction (SSI). A methodology based on hybrid Genetic Algorithm-Particle Swarm Optimization (GA-PSO) algorithm is proposed to determine the optimal parameters of TMD. For this purpose, three buildings (i.e., 3-story, 6-story, and 12-story buildings) are considered and the dynamic properties of these buildings are determined according to the provisions specified in ASCE-7. These buildings, which are frequently encountered in the traditional building stock, represent low, medium, and high-rise buildings, respectively. In the numerical analysis, three different soil types (i.e., SC, SD, and SE) and 80 ground motions are also considered. These records are divided into three different classes: high, intermediate, and low frequency content. The Newmark integration method is used to determine the dynamic responses of the structures in the time domain analysis. Numerical results show that the frequency content of ground motion and the slenderness ratio have a significant effect in reducing the peak displacement and acceleration responses of structures. The findings also demonstrate that when the PGA/PGV ratio is greater than 2, TMD shows mostly sufficient control performance for all buildings and all support conditions.

    Drivers of the Load Capacity Factor in New İndustrialized Countries: Economic Growth, Financial Development and Urbanization on Load Capacity Factor

    Durmus, Savas; Agırkaya, Melahat Batu; Akyol, Hikmet

    This study examines the effects of economic growth, financial development, and urbanization on the load capacity factor (LCF) for Newly Industrialized Countries (NICs) over the period 1991-2021. In this context, we analyzed the relationship between the variables using the Fixed Effects Driscoll-Kraay and Fixed Effects Panel Quantile estimators. The estimation results indicate that across all quantiles (low, medium, and high levels of environmental degradation), economic growth has a positive effect on LCF, while the squared term of economic growth has a negative effect. Urbanization and renewable energy consumption positively impact LCF, whereas financial development and labor force participation rates have negative effects. The positive effects of urbanization and renewable energy consumption on LCF become more pronounced in higher quantiles. Conversely, the negative impact of labor force participation on LCF is stronger in higher quantiles. The negative effect of financial development on LCF, however, becomes statistically insignificant at higher quantiles.

    Spatially explicit modeling of road icing susceptibility using GIS and a multi-criteria decision approach: A case study of Gümüşhane city (Türkiye)

    Işık, Fatih; Kanyılmaz, Rabia; Çağlak, Savas; Eraslan, Selim; Zeybek, Halil İbrahim

    This study develops and validates a GIS-based, spatio-temporal model to identify and prioritize road segments with high icing susceptibility in the Gümüşhane city center, Türkiye. Icing on urban roadways constitutes a significant threat to vehicular and pedestrian safety, particularly in regions characterized by complex topography and dense urban morphology. A Multi-Criteria Decision Analysis (MCDA) framework, employing the Analytic Hierarchy Process (AHP) with structured expert input, was used to synthesize ten primary causative factors. These include solar radiation, temperature, aspect, object height, precipitation, elevation, pavement material, slope, albedo, and road width — each representing a distinct topographic, climatic, or morphological influence on urban road icing. The AHP quantitatively established the relative influence of these factors, identifying solar radiation (28.5%), temperature (18.2%), and aspect (13.5%) as the most dominant drivers. The model generates monthly susceptibility maps that reveal "urban canyons"—narrow streets flanked by highrise buildings—consistently exhibit the highest and most persistent susceptibility due to severely limited solar radiation. The accuracy of the model's spatial predictions was quantitatively validated through field observations, with 91.4% of recurring icing locations correctly identified within high or very high susceptibility zones. This research culminates not only in a robust scientific framework but also in a validated decision-support tool that has been successfully integrated into the Gümüşhane City Information System (GCIS), where it is now operationally used to optimize winter maintenance strategies. Ultimately, this work provides a replicable, data-driven approach for enhancing urban resilience and traffic safety in challenging topographical settings.

    Chrome waste utilization in base layers: Mechanical strength and environmental risk assessment

    Seferoğlu, Mehmet Tevfik; Acı, Elif Nur

    This study investigates the partial substitution of natural aggregate (Na) with chrome mine waste (Crw) in highway base layers, focusing on mechanical performance and environmental safety. Crw-Na mixtures with contents from 0 % to 100 % were tested using CBR, cyclic plate loading, chemical, and leachate tests. The 15 % Crw-85 % Na mixture achieved the highest CBR (287.4 %) with limited deformation (37 mm). Although the 60 % Crw blend also met the required strength level (156.6 %), it showed higher settlement (50 mm) and three times greater vertical strain. SEM-EDX and chemical results indicated increased magnesium content and mineral changes at higher Crw ratios. Leachate tests confirmed compliance with TS266 and international water standards; all samples were categorized as neutral drainage with low metal risk. The findings show that Crw improves strength without causing environmental risk. Among tested mixtures, 15 % Crw offered the most balanced outcome in terms of field stability and performance.

    External Costs of Road Traffic Accidents in Türkiye: The Willingness-to-Pay Method

    Topcu, Rahmi; Coruh, Emine

    Traffic accidents remain a major global burden, causing mortality, disability, and socio-economic losses that hinder sustainable development. Beyond human suffering, crashes place long-term pressures on health systems, labor markets, and national economies, disproportionately impacting low- and middle-income countries. Estimating the true societal costs of accidents is therefore essential for designing effective, equitable, and sustainable road safety policies. This study applies the Willingness-to-Pay (WTP) method to evaluate the external costs of traffic-related deaths and injuries in Türkiye between 2008 and 2018. By incorporating material and immaterial losses, the WTP framework captures a broader spectrum of impacts than traditional approaches, offering valuable insights into the scale of welfare losses and the value of risk reduction. The findings reveal that external costs rose substantially over the decade, from 1.63% to 2.72% of national Gross Domestic Product (GDP), underscoring that economic losses from road crashes are growing faster than the economy. These results highlight the need for systematic interventions that integrate road safety into national sustainability agendas, including safer infrastructure, behavioral programs, advanced vehicle technologies, and efficient emergency response systems. The evidence presented strengthens the case for prioritizing traffic safety as a fundamental component of sustainable transport and public health strategies.

    Flexural Behavior and Sustainability of Dual-Waste Fiber-Reinforced Concrete Designed for Pavement Applications

    Seferoğlu, Mehmet Tevfik; Aksüt, Yavuz Selim; Seferoğlu, Ayşegül Güneş

    This study evaluates the mechanical performance and sustainability potential of fiber-reinforced concrete incorporating mine tailings as the fine aggregate and waste tire wire as the reinforcing fiber. The concrete mixtures contained 0.2%, 0.4%, and 0.6% waste tire wire with the natural fine aggregate replaced entirely with Pb-Zn-Cu tailings. The mixtures were tested for porosity, water absorption, compressive strength, splitting tensile strength, flexural strength, toughness, fracture energy, and ductility to assess their mechanical performance and durability. The mine tailings improved the microstructure and reduced water absorption, particularly with tire wire. Using waste tire wire improved the compressive, tensile, and flexural performance; in particular, W-6 showed a 18.2% rise in compressive strength and a more than twofold increase in flexural strength relative to the control mix. The flexural toughness and fracture energy rose by up to 161%, while the ductility peaked at a fiber content of 0.2%. These gains were attributed to fiber crack-bridging and post-cracking energy absorption. The dual-waste system also reduced porosity, improved durability, and demonstrated strong potential for rigid pavement applications such as highways, industrial yards, and airport runways that require high fatigue resistance and a long service life. Beyond technical performance, this approach offers a sustainable solution that lowers maintenance, reduces life-cycle costs, and aligns with circular economy principles.

    The evaluation of the mediation role of life engagement in resilience and trauma levels of individuals experiencing the earthquake in Kahramanmaraş, Türkiye

    Özmaya, Esma; Erkoç, Beyza; Kalaycı, Sami; Uzun, Sevda; Lotfi, Sayra

    The aim of this study is to evaluate the mediation role of life engagement in resilience and trauma levels of individuals experiencing the earthquake on February 6, 2023 in the city of Kahramanmaraş in Türkiye. The sample of this descriptive and correlational study included 1406 individuals. The questionnaire data was obtained through Google Forms and other data collection tools were Socio-demographic Information Form, Trauma Level Determination Scale, Short Resilience Scale and Life Engagement Scale. To analyse the data, frequency (percentage, arithmetic mean) and correlation analyses were used. Depending on the findings of the study, the resilience and trauma levels were negatively correlated, whereas the resilience and life engagement levels were positively correlated. Furthermore, the life engagement levels were negatively correlated with trauma levels while they were positively correlated with resilience. It was found that the life engagement played an mediation role in resilience and trauma levels of individuals experiencing the earthquake in Kahramanmaraş, Türkiye. In this study, we found that the life engagement has an important role in resilience and trauma levels of individuals. We are of the opinion that the findings of this study might help researchers and conductors to plan and perform effective strategies for post-impact phase of an earthquake.

    Optimal design of inerter-assisted series tuned mass dampers for seismic vibration control of multi-story buildings

    Araz, Onur

    This work introduces a framework for the optimal design of inerter-assisted series tuned mass dampers (STMDI) placed at the top story of a multi-story building under ground motion and performs comparative research to assess its effectiveness against conventional TMDI. The identical inertance ratio and total mass ratio are taken into consideration for the optimization of both control systems. In the frequency-domain analysis, the five design variables of the STMDI are optimized based on the minimization of the peak amplitude of the displacement transfer function at the top story of the building using the genetic algorithm (GA). The optimized variables are damping ratios (ξ1and ξ2), tuning frequency ratios (f1and f2), and mass ratio of the first to second TMD mass (µh). The proposed control system is applied to a 4-story, an 8-story, and a 16-story case-studies, and the optimal parameters are verified using eighty-five historical benchmark earthquakes in time domain analysis. These records are divided into three different groups according to their frequency content, i.e. PGA/PGV ratio: high, intermediate, and low. The results demonstrate that the STMDI performs better than the TMDI at the same mass and inertance ratio, especially at excitation frequencies close to resonance. The most important advantage of STMDI compared to TMDI is that it provides this performance in a wider frequency range and in an almost similar way. Finally, the seismic performances of STMDI and TMDI are compared considering ground motions with different frequency content.

    Effect of frequency content of ground motion on seismic response of buildings with variable aspect ratio including soil-structure interaction

    Kaya, Dilek; Cakir, Tufan; Ozturk, Kasif Furkan; Araz, Onur

    Soil-structure interaction (SSI) may lead to reduction, amplification or negligible change in structural responses depending on the relationship between the nature of excitations and subsoil conditions. Since neglecting SSI effects may cause uncertainties in seismic design, it is crucial to consider them during the design process. Another important factor affecting the dynamic behavior of structures interacting with the ground is the dynamic properties of the structures. To consider this effect, three buildings with 4, 8, and 12 stories designed in accordance with the Turkish Building Earthquake Code (TBEC-2018) are analyzed. The aspect ratios of these structures are 2, 4, and 6, corresponding to squat, ordinary, and slender structures, respectively. The primary objective of this study is to simulate the combined effects of these key parameters on the dynamic response of reinforced concrete structures. In the time history analyses, six ground motions classified by three different frequency contents are considered. 3D finite element models of SSI systems are established using ANSYS software. The usability of the numerical models is demonstrated for both SSI and fixed-base cases through three different analytical approaches. The displacement, acceleration, and stress responses are examined through time history analyses. The results indicate that the SSI is not negligible and neglecting the SSI is an oversimplification that does not lead to always-conservative predictions. Moreover, both the frequency content of the excitation and the structural aspect ratio are found to be decisive parameters in seismic response.

    Ecological effects of energy use and tourism-induced transport modes among coastline Mediterranean countries

    Cakir, Mehmet Ali; Recepoğlu, Mürşit; Alola, Uju Violet; Alola, Andrew Adewale

    Purpose: Motivated by the criticality of transportations system in tourism activities, this study further uncovers the effect of the main transportation modes arising from inbound tourism activities on the ecological footprint across the panel of selected coastline Mediterranean countries (CMC). Design/methodology/approach: The study considers a suitable econometric approach for the case of CMC with the dataset that covers the period 1998–2022. Findings: While the result reveals that all the modes of transportation except air deteriorate environmental sustainability by increasing ecological footprint in the long run, higher impact of environmental woe is associated with the land transportation. Similarly, the findings further show that economic expansion and conventional energy utilization in the examined panel and in each country spurs ecological footprint, thus worsening environmental quality. Meanwhile, for the country-specific observations, ecological footprint is (1) mitigated by tourism activities associated with air, water and land transports in Spain, (2) triggered by tourism activities associated with land transport in Croatia and (3) spurred by land transport in Italy. Originality/value: Policy inference from these results suggests the need to scale up the adoption of a low-emission transportation system in the countries.

    Evaluation of soil-structure resonance by determining local soil conditions in Gümüşhane city center

    Altundaş, Suna; Tanış, Abdulsamed

    Recent earthquakes have adversely affected human life, highlighting the necessity of identifying structural and ground conditions to assess risky areas and mitigate potential damage from future seismic events. Gümüşhane, the designated study area, is susceptible to the impacts of a possible earthquake due to its proximity to the North Anatolian Fault Zone (NAFZ). Accordingly, vertical electrical sounding (VES), multi-channel analysis of surface waves (MASW), and microtremor methods were employed in the central district of Gümüşhane to characterize local ground conditions and to evaluate the resonance hazard potential arising from the interaction between structures and the underlying soil. Dominant period (T0) and frequency (f0), spectral amplification (A0), soil index of vulnerability (Kg), average S wave velocity for 30 m depth (Vs30), ground type, and soil-structure resonance hazard potential were determined. For the study area, f0 values between 1.32–8.91 Hz (T0 values varied between 0.11–0.76 s), A0 values between 0.93–7.63 according to horizontal/vertical spectral ratio (HVSR) analysis, and Vs30 values were between 390–886 m/sec to MASW. As a result of the evaluation of microtremor measurements made in all buildings using the floor spectral ratio (FSR) technique, the soil-structure potential resonance hazard was found to be low. The present study, conducted in Gümüşhane, examined the subject of soil-structure interaction. In the process of planning new residential areas, it is imperative to ensure the reliability of construction based on the local ground conditions. Furthermore, it is essential to determine the risk status of buildings in relation to potential earthquake movements.

    Depremde Kadın Olmak: Osmaniye Düziçi Çadır Kent Örneği

    Akbal, Alev; Taşbaş, Sultan

    Teknolojinin gelişmesi, kurumsallaşma düzeyinin yüksek olması, iş sahalarının fazlalılığı ve çeşitliliği nedeniyle insanlar yaşamak için kentsel yaşam alanlarını tercih etmektedirler. Kırsal alandan kente yoğun göçün yaşanması kentlerde yeni yerleşim yeri arayışının artması, alt yapı sorunları, ulaşım problemleri, eğitim ve sağlık sorunlarının armasına neden olmaktadır. Bununla birlikte coğrafi koşulların uygun olmamasına rağmen yani doğal afetlerin görülme riskinin yüksek olmasına rağmen insanların afet bölgelerine yerleşim yeri kurmasına neden olmaktadır. Bu durum ise herhangi bir afetle karşılaşılması durumunda toplumsal direncin düşmesine ve kırılganlıkların artmasına neden olmaktadır. Dirençlilik kişilik özellikleri, cinsiyet, eğitim durumu, toplumsal statü, kentsel alt yapı, coğrafi konuma göre değişkenlik göstermektedir. Dezavantajlı gruplar ise bu afetlerden çok daha fazla etkilenmektedir. Dezavantajlı gruplar arasında tanımlanan kadınların direnci sahip oldukları toplumsal cinsiyet rollerinden dolayı daha düşük konumdadır. Bu kapsamda depremde kadının toplumsal cinsiyet eşitsizliğinin beraberinde getirdiği dezavantajlılığın kadınların kırılganlıklarını artırması çalışmanın temel problemini oluşturmaktadır. Depremde kadınların toplumsal cinsiyet rollerinden kaynaklanan kırılganlıklarını ve bu kırılganlıkların nedenlerini ortaya koymak çalışmanın temek amacını oluşturmaktadır. Çalışma üç bölümden oluşmaktadır. Birinci bölümde kadının toplumsal cinsiyet rolleri , doğal afetler ve doğal afetlerin ortaya çıkardığı kırılganlıklar ve çalışmanın yöntemine ilişkin bilgiler yer almaktadır. İkinci bölümde çalışmanın araştırma bulgularına yer verilmekte ve afetzede kadınların depremde yaşadıkları kırılganlıklar sosyolojik açıdan tartışılmakta; sonuç bölümde ise elde edilen bulgulara ilişkin kavramsal ve kuramsal tartışmalar yer almaktadır.

    Evaluation of the Exposure of 4.5G Mobile Phone Base Stations in Different Band Radio Frequencies in Urban Center and Rural Areas in Turkey.

    Tören, Murat; Ulutaşdemir, Nilgün

    Mobile phone base stations (MPBS) are electronic communication equipment, the number of which is rapidly increasing with the increasing need for mobile data use with developing technology. Since the middle of the 21st century, the effects of Radio Frequency Electromagnetic Fields (RF-EMF) emitted from base stations on human health have begun to be investigated. Although some of these studies have explained the harmful effects of RF-EMF on human health, others have stated that its effects on human health are limited and therefore contradictory results have emerged. RF-EMFs can have effects by transferring energy to human tissues, increasing temperature and changing the way cell membranes work. These effects may vary inversely with the proximity of MPBSs to residential areas and their safety distances. In this regard, rules such as location at least 300 m away from places with high population density (schools, hospitals, shopping malls, etc.) and at least 40 m above the ground are required. In this study, RF-EMF values of base stations installed both in Rize city center and rural areas in Turkey in different 4.5G frequency bands (GSM 900 DL- 1800 DL-2100 DL) were analyzed by real-time selective area analyzer (NARDA- It is measured using SRM 3006). The safety distances in the production/label values of these base stations, mathematically calculated EMF and measurement values were compared for different distances. Base station production/label and real-time measurement values of RF-EMF values emitted by MPBSs in urban centers and rural areas are determined and their effects on human health are evaluated.

    Üniversite Öğrencilerinin Afet Algı Düzeylerinin Değerlendirilmesi: Örnek Bir Uygulama Çalışması

    Doğan, Onur; Demırag, Ozgül

    Afetler, öngörülmesi zor ve çeşitli şekillerde ortaya çıkan, çoğu zaman tahribat gücü yüksek önemli doğal-doğal olmayan olaylardır. Deprem, taşkın, kuraklık, büyük endüstriyel kazalar, kıtlık, teknolojik kazalar, salgınlar vb. geçmişten günümüze insanoğlunun maruz kaldığı büyük afet türlerinden yalnızca birkaçıdır. Son yıllarda gerek Türkiye’de (Düzce-deprem, 1999; Giresun-Dereli-sel-taşkın, 2020; Kahramanmaraş-Pazarcık-deprem, 2023) gerekse dünyanın diğer birçok bölgesinde (Sumatra-tsunami, 2004; Ekvador-deprem, 2016; ABD-hortum-fırtına, 2023) çeşitli afet olayları yaşanmaktadır. Afetlerin etkisi çoğu zaman bir bölge ile sınırlı kalmayıp geniş bir alana yayılım gösterebilmektedir. Nitekim afet öncesinde alınabilecek çeşitli tedbirler sayesinde bu tahribatın etkisi bir noktada azaltılabilir. Örneğin bölgesel risklerin tespit edilmesi, erken uyarı sistemleri, kriz yönetimi, acil eylem planları, vb. bu tedbirler kapsamında değerlendirilebilir. Bir diğer önemli husus ise toplumun afet farkındalık düzeylerinin artırılmasıdır. Özellikle afet risk haritası çıkarılmış bölgelerde bu tür farkındalık artırma çalışmaları yapılarak toplumun afet karşısında göstereceği tepki daha kontrollü ve bilinçli hale getirilebilir. Bahsi geçen hususlar bu çalışmanın ana hedefini oluşturmaktadır. Bu çalışma, Gümüşhane Üniversitesi merkez kampüs öğrencilerinin afet farkındalık düzeylerinin değerlendirilmesi amacıyla yapılmış bir çalışmadır. Çalışmada elde edilen veriler SPPS 25 istatistik programı kullanılarak analiz edilmiştir. Çalışmada afet risk algısını ölçmeye yönelik 5’li Likert kullanılmıştır. Çalışmada, frekans analizi testi, Kruskal Wallis testi ve Mann Whitney U testi yapılmıştır. Analiz sonucunda %5 anlam düzeyinde (p&lt;0,05) analiz edilmiş olup tablolarda aritmetik ortalama, standart sapma ve birey sayısı yüzdesi şeklinde belirtilmiştir. Buna göre non-parametrik Mann Whitney-U testi sonucun-da, gruplar arasında anlamlı bir fark bulunmamıştır. Öğrencilerin afet risk algısı alt boyutu puanlarının cinsiyet değişkenine göre anlamlı bir şekilde farklılaşıp farklılaşmadığını belirlemek üzere yapılan non-parametrik Mann Whitney-U testi sonucunda gruplar arasında afete maruz kalan grup lehine istatistiksel açıdan p&lt;0,05 düzeyinde anlamlı bir farklılık saptanmıştır.

    مدينة حلب في روايات أحمد زياد مُحَبِّك

    الأحمد, محمد

    تناولت الدراسة مدينة حلب في روايات أحمد زياد محبك، وتوقفت عند بناء المكان الحلبي في هذه الروايات، ورصدت فيه قلعة حلب وأحياءها وشوارعها وحدائقها ومساجدها وغيرها من الأماكن العامّة فيها. وتتبعت الدراسة البيت الحلبي بنوعيه القديم والحديث. وتتبعت الدراسة أيضًا أسماء المجتمع الحلبي الروائي، وظهر للباحث أنها تنتمي إلى عدة منظومات، ولا سيما المنظومة الدينية والاجتماعية والمستحدثة. وتوقفت الدراسة عند ملابس المجتمع الحلبي ومعتقداته وأطعمته وأشربته وأمثاله الشائعة بين أفراده وعاداته وتقاليده والأغاني التي اعتاد عليها هذا المجتمع. وتوصلت الدراسة إلى عدد من النتائج يأتي في مقدمتها أنّ مدينة حلب شكّلت المركز الذي دارت حوله معظم الأحداث التي تضمنتها روايات أحمد زياد محبّك، وبدا الروائي حريصًا على تقديم مدينة حلب على نحو يكاد يطابق الواقع، وبدا أنّه يريد أن يحفظ هذه المدينة رواية كي يتسنى للقارئ معرفة هذه المدينة ويكوّن صورة واقعية عنها خلال الفترة الممتدة منذ منتصف القرن العشرين حتى أوائل القرن الحادي والعشرين.
