- MakaleAçık Erişim2026Afet Hazırlığında Stratejik Adım: Tunceli Merkez İlçesi Toplanma Alanlarının AHP ile Analizi
Ogedey, Aysenur
Tunceli, zorlu arazi yapısı ve sert iklim koşulları nedeniyle yaşamın güç olduğu bir bölgedir. Kar yağışlarının yoğun olduğu kış ayları ve düşük sıcaklıklar, engebeli topoğrafya ile birleşerek çeşitli afet risklerini artırmaktadır. Bu koşullar, bölgede afet ve acil durum yönetiminin özel planlama ve hazırlık gerektirdiğini göstermektedir. Bu çalışmada, Tunceli’deki toplanma alanlarının değerlendirilmesi amacıyla Çok Kriterli Karar Verme yöntemlerinden Analitik Hiyerarşi Süreci kullanılmıştır. Analitik Hiyerarşi Süreci, ana ve alt kriterler arasındaki önceliklerin belirlenmesine olanak sağlayarak afet yönetimi süreçlerinde karar vermeyi sistematik hâle getirmektedir. Analiz sonuçları, ana kriterler arasında en yüksek ağırlığa sahip faktörün “toplanma alanı güvenliği” olduğunu (0,707) ortaya koymuştur. Alt kriterler kapsamında ise “toplanma alanı özelliği” içinde “erişim ve tahliye kolaylığı” (0,559) ve “erişim” ana kriteri altında “tabela, kroki ve işaretleme ile yer belirleme” (0,550) öne çıkmaktadır. Bulgular, Analitik Hiyerarşi Süreci’nin Tunceli’de afet toplanma alanlarının güvenlik ve erişilebilirlik odaklı planlamasında etkili bir araç olduğunu göstermektedir. Çalışma, ayrıca afet yönetimi uygulamalarında bilimsel ve sistematik karar verme yöntemlerinin önemini vurgulamaktadır.

Güngör, Gizem Nur
Kırsal mimarlık mirasının karşı karşıya kaldığı ve yeterince ele alınmayan sorunlarından biri, koruma ile ilgili politikalarda da tamamen terk dışında değinilmeyerek boşlukları olan mevsimlik kullanımdan kaynaklı problemlerdir. Bu çalışma ilgili boşluğa işaret ederek mevsimsel kullanıma dönüşen bir kırsal konut örneğinin yalnızca yapısal niteliklerini değil kullanım döngüsünü de değerlendirerek ihtiyaca yönelik müdahalelerle tanımlanmış bir koruma planlaması geliştirmeyi amaçlamaktadır. Bu çalışmanın özgün değeri seçilen örnek yapının tamamen terk edilmiş olmamakla beraber tamamen aktif olarak da kullanılmıyor olmasıdır. Söz konusu yapıda kullanım sürekliliğinin olmaması koruma ölçütleri bakımından değerlendirildiğinde olumsuz bir durumdur. Çalışmada belirlenen örnek üzerinden benzer durumdaki yapılar için uygulanabilir bir koruma kullanma dengesi çerçevesi çizmek ve korumayla ilgili karar süreçlerine rehberlik edecek bir yaklaşım önermek hedeflenmiştir. Bu doğrultuda yapının özgün nitelikleri belgelenmiş, mevcut koruma sorunları tanımlanmış kullanım sürekliliğindeki kırılmaların ortaya çıkardığı riskler değerlendirilmiştir. Evrensel koruma politikaları gözetilerek, yapının kullanıcı ihtiyaçlarına cevap verebilmesi ve kültürel miras değerinin gelecek kuşaklara aktarılabilmesi için gerekli müdahalelerin kapsamı belirlenmiştir. Bu kapsamda yapı ve yakın çevresinde sürekli kullanımı teşvik eden öneriler öncelikli hedef olarak tanımlanmış, bu hedefler hayata geçirilene kadarki mevsimsel kullanım süreci ise ayrı bir senaryo olarak ele alınmıştır. Böylece korumada süreklilik sağlanana kadar geçiş dönemine özgü koruma yaklaşımları geliştirilerek yapının fiziksel ve kültürel sürekliliğini destekleyen bir müdahale modeli önerilmiştir.
- MakaleAçık Erişim2026Comparative Analysis of the Seismic Risk of Tunceli-Ovacık Rural Building Stock Using Different Rapid Screening Methods
Polat, Berivan Yılmazer; Ayhan, Ezgi
Located at the intersection of the Yedisu Segment, a seismic gap, and the active Ovacık Fault, the Tunceli-Ovacık district is a region with a high earthquake risk but an unclear level of structural fragility. This study aims to assess the seismic safety of the rural building stock located in a seismically critical area. To this end, the Turkish Rapid Visual Screening (RVS), based on local parameters, and the Canadian Seismic Survey Method, widely used in international literature, were applied to determine the current condition of the buildings; the earthquake risk of the region was analyzed based on the results obtained. Furthermore, similarities and differences between the methods were comparatively examined to ensure scientific integrity. Within the scope of the study, 209 buildings representing the building typology in the region, 88% of which are masonry-mixed systems, were analyzed using both rapid assessment algorithms. While the overall risk distribution ratios were similar, building-level matching analyses showed a medium level of agreement between the methods. This indicates that the local and universal methods, rather than definitively verifying each other, provide complementary data by focusing on different parameters in the seismic assessment of the rural building stock. This study demonstrates that an integrated risk mapping approach, where different methodologies complement each other, can offer a rapid and reliable decision support mechanism for urban transformation strategies in cities with high earthquake risk, such as Tunceli.

Gundogdu, Yunus Emre; Polat, Berivan Yilmazer
This study, which was conducted in the P & uuml;l & uuml;m & uuml;r district of Tunceli, was carried out in an area with high seismic risk due to the region's proximity to the Bing & ouml;l-Yedisu Fault. In the study, the earthquake safety of the existing building stock was assessed using visual inspection methods. In this context, 172 buildings in the P & uuml;l & uuml;m & uuml;r district of Tunceli province were examined in detail in terms of earthquake safety using the Canadian Seismic Screening Method. In the analysis, seismic safety levels of the buildings, structural and nonstructural risks were taken into consideration and seismic priority indexes (SPI) were determined. The results of the study revealed that a large portion of buildings in the P & uuml;l & uuml;m & uuml;r district carry different levels of risk of earthquake. Specifically, the evaluated building stock was entirely constructed before the critical year of 2007 and exhibits high seismic vulnerability. This critical threshold is technically attributed to two main regional factors: the design practices predating the 2007 Turkish Earthquake Code and the absence of ready-mixed concrete technology in Tunceli province prior to that year. Furthermore, based on the method's classification, it is suggested that buildings with a Seismic Priority Index (SPI) greater than 20, which indicates High to Very Hazardous risk levels, should be prioritized for detailed assessment and retrofitting, and that local governments should develop incentive policies for these mitigation efforts.

Sen, Bugra; Polat, Alper; Kapicioglu, Abdullah; Esen, Hikmet
In the present study, energy is harvested from vibrations in bridge structures caused by vehicle passages using piezoelectric energy harvesters (PEHs). In order to maximize the energy harvested, it was aimed to specify the optimal locations of PEHs. In the study, energy harvesting from vibrations in bridge structures was achieved using three different vehicle loads and three different piezoelectric materials. The project of the Ku & scedil;saray & imath;-2 bridge, located in Ku & scedil;saray & imath; village in Baskil, Elaz & imath;& gbreve;, was modelled in the ANSYS program using real measurements. The bridge was analyzed for modal, harmonic, and piezoelectric energy harvesting, respectively. The type with the highest energy production was determined using three different piezoelectric materials (PZT-4, PZT-5A, and PZT-8) for a total of 9 PEHs, and a total of 13 different analyses were performed under three different vehicle loads (60 kN, 90 kN, and 120 kN) to compare the results. The maximum total power obtained from all nine PEHs was 1.484 & micro;W under the 120 kN load with PZT-5A. The maximum power obtained from a single PEH (PEH-1) was 0.49 & micro;W. This power achieved will be adequate for wireless sensor systems used for monitoring the structural health of bridges, and considering that energy harvesting through vibration is independent of meteorological elements, unlike energy sources such as solar and wind, the environmental damage caused by waste batteries in existing systems will be prevented with the dissemination of these systems. With the development of these systems, the energy needs of services such as lighting and traffic signs can be supplied. The results provide an important foundation for the development of vibration-based energy harvesting systems in bridge structures. Thus, the study stands out as an innovative step toward sustainable energy generation in structural engineering.

İçen, Abdullah; Ilki, A.; Goksu, C.; Cinar, T.; Erdik, M.
This study investigates basin, basin edge and complex topography effects in ground motion records using residuals from empirical ground motion models, to better understand regional site amplification patterns in Türkiye. Using data from the updated Strong Motion Database of Türkiye (SMD-TR) strong-motion database, we compute residuals using site amplification function and analyze their spatial distribution across regions. The clustering technique, Gaussian Mixture Models (GMM), is employed to identify regions with coherent residual patterns, primarily to capture regional site effects. After regionalization, peak amplifications within the VS30 range of 400–550 m/s are examined for potential associations with sedimentary basins or basin edge effects. The results reveal systematic amplification anomalies within the VS30 range of 400–550 m/s that are not fully captured by conventional site proxies such as VS30. Notably, residuals consistently cluster along basin edges and within deep valley regions, indicating the influence of complex three-dimensional and topographic amplification mechanisms. These observations underscore the limitations of current site characterization approaches and motivate further refinement of site response models, particularly for partially non-ergodic applications in seismic hazard analysis. This study focuses on residual-based evaluations to identify potential basin, basin-edge, and topographic effects that warrant more detailed investigation.
- MakaleAçık Erişim2026Scopus SJRQ4Sustainable land management under uncertainty: A hybrid Bayesian BWM and RPM framework for spatial prioritization
Konurhan, Zekeriya
Sustainable land management is a complex problem due to environmental constraints and decision-maker uncertainty. This study presents an integrated solution combining Geographic Information Systems (GIS), the Bayesian Best-Worst Method (Bayesian BWM), and the Ratio Product Model (RPM) to improve the accuracy of spatial prioritization in land-use decisions. The integration of the Bayesian BWM and RPM statistically minimizes the cognitive uncertainty in expert opinions whilst enabling the most suitable areas to be ranked with precision within their own categories, without any normalization constraints. The proposed model was developed for three main categories —residential, industrial, and agricultural— in the province of Balıkesir. The analysis results revealed that the ‘ease of access to services’ (0.5660) criterion was the most decisive factor for residential suitability, whilst ‘distance to power transmission lines’ (0.1322) and ‘average rainfall’ (0.1315) were the most decisive factors for industry and agriculture, respectively. The suitability maps show that the Bandırma-Susurluk corridor is strategically prioritized for industry, whilst the Manyas-Gönen basin is prioritized for agricultural production. RPM scores (0.2750 for settlement, 0.6036 for industry, and 0.3868 for agriculture) quantify implementation priorities, providing a reliable decision-support tool for managing uncertainty in spatial planning.

Tektaş, Şeyhmus; Tam, Gürkan; Yön, Burak
This study evaluates the effect of soft-storey irregularity on the seismic fragility of reinforced concrete buildings by comparing fragility curves based on inter-storey drift and element damage. This comparison highlights the novelty of the study. For numerical analyses, a typical four-storey reinforced concrete building with a ground storey of 4.5 m and typical storeys of 3 m, having a current storey plan, was modeled as both a regular and soft-storey building. To model nonlinear behavior, the assumption of lumped plastic hinges at the ends of the structural elements was made. Static pushover analyses of the building models created in SeismoStruct 2022 were performed until the roof displacement reached 3% of the building height, while nonlinear incremental dynamic analyses were carried out using 11 real ground motion records obtained from AFAD. The records were scaled between 0.1 g and 1.0 g and applied in the x- and y-directions for both buildings, yielding a total of 440 dynamic analyses. Static pushover analyses generated capacity curves for both regular and soft-storey buildings. Incremental dynamic analyses revealed maximum responses, inter-storey drifts, damage distributions, and fragility curves for both regular and soft-storey buildings. Fragility curves were obtained using both HAZUS inter-storey drift limit values and TBEC 2018 section-based strain limits. The results showed that fragility curves generated based on inter-storey drifts yielded more sensitive results than those generated based on damage at the critical storey. Furthermore, it was determined that for an earthquake acceleration of 0.5 g, the probability of a soft-storey building collapsing was 30% higher than that of a regular building.
- MakaleAçık Erişim2026Scopus SJRQ1Failure of a Code-Compliant Reinforced Concrete Building: Damage Patterns and Nonlinear Seismic Response
Onat, Onur; Karaşin, İbrahim Baran; Yön, Burak; Varolgüneş, Sadık; Öncü, Mehmet Emin; Uslu, Ali
This study investigates the seismic performance limitations of a newly constructed reinforced concrete building that collapsed during the 6 February 2023 Kahramanmaraş–Elbistan earthquake despite formal compliance with current seismic design requirements. Beyond the specific earthquake event, the study addresses a broader scientific problem: the limited understanding of the relationship between observed damage mechanisms and nonlinear dynamic response in mid-rise reinforced concrete buildings. The first part classifies recurring structural and non-structural damage patterns identified in newly constructed RC residences. The second part presents a nonlinear fiber-based static and dynamic analysis of a collapsed mid-rise building. Nonlinear dynamic analyses were conducted using ground motion records scaled to match the site-specific elastic design spectrum defined by TBDY 2018, corresponding to predefined seismic performance levels rather than an incremental dynamic analysis framework. The results indicate that an extremely low shear wall–to–floor area ratio (0.0357%) combined with asymmetric vertical element distribution significantly amplified torsional response and local shear demands. Nonlinear dynamic analyses showed that critical shear walls exceeded Collapse Prevention limits under DD2-level excitation, while system-level shear contribution limits remained within code-defined thresholds. Dynamic base shear demand corresponded to approximately 30% of the maximum nonlinear capacity obtained from pushover analysis, indicating that localized member failure rather than global strength deficiency governed the collapse mechanism. The analytically identified critical members were consistent with the observed collapse configuration, particularly at the soft ground story. The findings demonstrate that prescriptive code compliance alone may not ensure satisfactory seismic performance when structural irregularities, torsional amplification, and detailing deficiencies coexist. The results are consistent with damage patterns reported in other recent destructive earthquakes and contribute to improving the understanding of collapse mechanisms in code-compliant RC buildings.

İncele - MakaleAçık Erişim2026Scopus SJRQ1Post-disaster psychological effects: identifying earthquake-induced trauma in athletes
Uğurlu, Fatih Mehmet; Güler, Muhammed; Albayrak, Veysel; Aygören, Caner
Natural disasters not only cause physical destruction but also lead to various psychological problems affecting the mental health of individuals. This study was conducted to determine the levels of post-earthquake trauma in athletes who experienced earthquakes and whether certain variables made a difference in this situation. The sample of the study consisted of 359 athletes living in 11 provinces affected by the earthquakes centered in Kahramanmaraş, Turkey, on February 6, 2023. Participants were reached using the Snowball Sampling Method. The Sociodemographic Information Form and the Post-Earthquake Trauma Level Determination Scale were used to collect data. As a result of the descriptive statistics, it was seen that athletes experienced above-average earthquake trauma (M = 65.84). When examined in terms of sociodemographic variables, it was found that women showed more symptoms of earthquake trauma than men, those who experienced the loss of relatives showed more symptoms than those who did not, and those who experienced the loss of a home showed more symptoms than those who did not. In conclusion, while exercise and physical activity are methods used to cope with trauma, being an athlete alone is not sufficient to cope with earthquake trauma. Women, whether athletes or not, experience more earthquake trauma than men. Losing relatives exacerbates the trauma caused by the earthquake. Furthermore, the loss of a home, which prevents individuals from meeting some basic physiological needs, is a significant factor in earthquake trauma.

Polat, Elifcan Göçmen; Polat, Erkan
Disasters bring about significant material damage and social disruptions, affecting entire communities or specific groups. These events can halt daily life and human activities, often exceeding the handling capacity of the affected population. For effective disaster management, all stages-including prevention, mitigation, preparation, response, and recovery must be spatially planned. The identification of post-disaster assembly areas is critically important for minimizing loss of life and property. This study examines theoretical and practical research on assembly areas from the literature. In determining suitable assembly areas, factors such as population density, accessibility, proximity to hazard sources, land type, and access to essential services and methods as Geographical Information Systems (GIS) and Multi-Criteria Decision Making (MCDM) provide valuable framework for addressing assembly area selection challenges. Findings from the literature indicate that the assembly areas should be reassessed in the context of evolving needs and regulatory requirements.

Elde edilen bulgular, üniversitenin kurulmasının Gümüşhane kentinin demografik yapısını önemli ölçüde etkileyerek, büyük bir konut talebi yarattığını ortaya koymaktadır. 2008 yılında kurulan Gümüşhane Üniversitesi’nin hızlı büyümesi, öncelikle öğrenci ve akademik personel akını nedeniyle nüfusta önemli bir artışa yol açmış ve böylece yeni konutların yapımına yönelik büyük bir talep artışı ortaya çıkmıştır. Bu durum 2008'den sonra, kullanım izni olan konut amaçlı bina ve daire sayısında belirgin bir artışı da beraberinde getirmiştir. Üniversitenin kurulduğu 2008 öncesinde kentte yılda ortalama 11 konut amaçlı bina kullanım izni alırnırken, bu rakam 2009- 2023 döneminde 25’e ulaşmıştır. Kentte üretilen daire sayısında da benzer bulgular elde edilmiştir. 2008 öncesinde kentte yılda ortalama 135 daire kullanım izni alırken, bu rakam 2009-2023 arasında 414’e yükselmiştir. Çalışmanın bir diğer önemli bulgusu, yeni inşa edilen binaların yalnızca sayıca artmakla kalmayıp aynı zamanda daha yüksek katlı bina üretimine doğru güçlü bir eğilim göstermesidir. 2002-2008 arasında Gümüşhane kentinde 10 ve daha çok katlı bina bulunmazken, özellikle 2015 yılından sonra bu tip yüksek binalar en yaygın yapı tipi olmuştur. Konut üretiminde çok katlı yapıların giderek önem kazanmasında Gümüşhane’nin coğrafi özelliklerinin de rol oynadığı belirlenmiştir. Bu değişim, şehrin geleneksel konut düzeninin ve mekânsal yapısının dönüşümüne katkıda bulunmuştur. Sonuç olarak, Gümüşhane Üniversitesi'nin kurulması şehrin demografik ve fiziksel görünümünü önemli ölçüde dönüştürmüş ve üniversiteyi yerel konut piyasasında önemli bir oyuncu haline getirmiştir.

Tunceli 1935 yılında vilayet haline getirilmiştir. 1937 yılında Kalan kazası kurulmuş ve bu yeni vilayetin idari merkezi yapılmıştır. 1952 yılında “Kalan” kazasının adı Tunceli olarak değiştirilmiştir. Tunceli bütünüyle bir Cumhuriyet kentidir. Kentin kuruluşu, yamaçlarında köy yerleşimi bulunan dar ve “boş” bir plato alanına bazı resmi yapıların inşasıyla başlamıştır. Zamanla memur lojmanları ve halkın iskânıyla nüfuslanan yerleşme, kısa sürede kasaba büyüklüğüne ulaşmıştır. Bu bağlamda Tunceli kentinin kuruluş yerinin belirlenmesinde kentleşme hedeflerinden ziyade konjonktürel nedenler etkili olmuştur. Kent yerleşimi zaman içinde genişlemiş ve kuruluş yerinden taşmıştır. Günümüzde kent 8 mahallesiyle 27 km²’lik bir alanda yayılış göstermektedir. Nüfusu 36 bin kişidir (2023). Kent, topografik engeller nedeniyle büyük ölçüde riskli zeminler üzerinde gelişmektedir. Zaman zaman gerçekleşen kütle hareketleri ve Yedisu Fayı’nın yakın vadede üretmesi beklenen yıkıcı deprem, yerleşmeleri tehdit etmektedir. Kent yerleşimi, beklenen deprem ve kentleşmeyi olumsuz etkileyen topografyası nedeniyle 15 km kadar güneye, Yeniköy mevkiine taşınmalıdır. Yeniköy mevkii 87 km² kadar alanıyla sağlıklı bir kentsel yapılaşma için jeolojik, topografik ve ulaşım altyapısı açısından oldukça elverişli özelliklere sahiptir. Bu çalışma mevcut kent yerleşmesinin bulunduğu yer nedeniyle karşı karşıya olduğu sorunları ve önerilen yeni kent alanının niteliklerini belirleyerek, kentin geleceğine ilişkin bir vizyon oluşturmayı amaçlamaktadır.

Addressing the issue of inadequate engineering properties in soil is crucial for enhancing structural behavior and reducing damages, especially during seismic events. This study addresses the critical issue of inadequate engineering properties in soil and their impact on structural behavior, particularly during seismic events. Employing a case study methodology, structural responses are assessed before and after soil improvement, emphasizing the problem's significance. Site response analyses for pre-improvement phases reveal design insufficiencies and areas prone to soil liquefaction. The proposed solution is soil reinforcement through cement injection. Examining six cases under various earthquake scenarios and ground conditions, 132 dynamic analyses are conducted, highlighting substantial improvements post-soil improvement, especially in Interstory Drift Ratios (IDR) and roof drift ratios. These findings underscore the effectiveness of soil reinforcement in mitigating seismic damage, emphasizing its critical role in enhancing structural behavior and contributing to a better understanding of addressing soil inadequacies for improved seismic performance.

In this study, the effect of retrofitting with steel bracing members on the seismic behavior of reinforced concrete buildings was examined. A reinforced concrete building with low concrete strength was modeled for the numerical study. This modeled building was strengthened with steel X-braced members to create a total of two buildings. To evaluate the seismic behavior of the modeled buildings, incremental dynamic analyses were performed using static pushover analysis and 11 different earthquake records. Due to the symmetrical structure of the modeled buildings, a total of 220 analyses were carried out simultaneously in the x and y directions. As a result of the analysis, the capacity curves of the existing building and the strengthened building with steel bracing members, maximum responses, inter-storey drifts, and fragility curves according to the damage status were obtained. As a result of the analysis, it was determined that the maximum response of the building strengthened using X steel cross members increased significantly compared to its current state, while the damage to the structural elements was significantly reduced.

This study examines land use/land cover (LULC) scenarios and identifies areas suitable for settlement on the Datça Peninsula. Datça is one of the four peninsulas in the Aegean Sea and is administratively part of the Muğla province of Türkiye. Forests prevail across the landscape, especially around the stretch shaped by the Datça–Marmaris highway, while agriculture is concentrated on the Datça Plain, Cumali, and Yaka. This study aims to determine land use scenarios and identify suitable areas for future development and settlement. The GeoSOS-FLUS software package, developed based on Markov Chains and Artificial Neural Networks for land use simulations, was used. Aware of the limitations of simulations that do not consider land suitability, a suitability analysis was performed using the Best-Worst Method (BWM), one of the Multi-Criteria Decision Making approaches. Sixteen criteria within four groups—topography, socioeconomics, location, and environment—were evaluated. The suitability analysis results were compared with simulated land use scenarios, and the most suitable areas for future settlements in the Datça Peninsula were identified. This integrated approach provides important information for the sustainable development of the region and the shaping of land use planning.

Furtana, Beyza
This study investigates the physical and rheological properties of asphalt binders recovered from earthquake damaged road sections in Hatay, Kahramanmaras, Gaziantep, and Malatya following the February 6, 2023, earthquakes in southern Türkiye (Mw = 7.8 and Mw = 7.5). Asphalt mixture samples were collected from severely deteriorated pavements, and bitumen was extracted through solvent extraction and rotary evaporation. The recovered binders were subjected to penetration, softening point, rotational viscosity, and Dynamic Shear Rheometer (DSR) tests to evaluate aging, stiffness, high-temperature performance, and viscoelastic behavior. Results revealed significant regional differences: Hatay binders exhibited the lowest penetration, highest softening point, highest viscosity, and the greatest rutting resistance (high G*/sinδ values) while maintaining lower phase angles, indicating enhanced stiffness and elasticity. In contrast, Kahramanmaras binders showed the highest penetration, lowest softening point, and lower viscosity, combined with high phase angles, reflecting a softer, more viscous character with reduced deformation resistance. Malatya and Gaziantep binders displayed intermediate characteristics, with Malatya showing moderate stiffness and Gaziantep retaining greater flexibility. Across all samples, viscosity decreased markedly with increasing temperature, and rutting resistance diminished at higher service temperatures; however, binders with higher initial G*/sinδ values retained better performance. The findings highlight the influence of regional seismic intensity, climatic conditions, and pavement history on binder behavior and emphasize the need for region-specific maintenance and rehabilitation strategies in post-disaster pavement management.

Ertarğın, Merve
Electric vehicles (EVs) have emerged as a cornerstone in the transition toward sustainable transportation, offering a cleaner alternative to conventional fossil fuel-based mobility. Their integration into modern transportation systems not only supports global decarbonization efforts but also requires robust energy management solutions to address the growing demands on charging infrastructure. Ensuring efficient energy consumption forecasting is vital for optimizing EV charging station operations and maintaining grid stability. This study aims to predict the daily energy consumption of an EV charging station using a public dataset. Key features such as charging duration, vehicle count, mean and median connection time were utilized for the prediction. Both the original dataset and its z-score-cleaned version were employed to evaluate the models' performance under different data conditions. Decision Tree (DT), Random Forest (RF), Extreme Gradient Boosting (XGBoost) and Light Gradient Boosting Machine (LightGBM) models were implemented, with hyperparameter optimization conducted via GridSearchCV. The results revealed that all four models achieved high accuracy in predicting daily energy consumption across both datasets, with R2 values exceeding 0.97. Specifically, for the z-score-cleaned dataset, LightGBM demonstrated the best performance with the lowest RMSE (37.35 kWh) and MAE (28.93 kWh), as well as the highest R2 value (0.9727) followed by XGBoost, RF and DT.

Yine Türkiye’deki belediyelerin hizmetlerinin ekseriyetle sosyal yardımlar niteliğinde olduğu, sosyal hizmet uzmanlarının mesleki müdahalelerinin apolitik düzlemde değerlendirilmediği, bu hizmetlerin halkın ihtiyacı, belediyenin bütçesi, ilin nüfusu, belediyenin büyükşehir-il-ilçe belediyesi olma durumuna göre değişkenlik gösterdiği, yaşanılan sorunların daha yapısal çözümlerle; yeni sosyal politikalar, tüm belediyelerin kullandığı entegre bir sistem ve ortak projelerle kapsayıcı boyutta geliştirilebileceği vurgusu sosyal hizmet uzmanlarının sahadan aktardıkları deneyimleri sonucunda ortaya konmuştur.
