Gücer, Mehmet Ali; Çimen, Okay; Aktağ, Alican; Keskin, Serdar
The growing demand for critical minerals driven by the global energy transition and advanced technologies highlights the importance of unconventional metal reservoirs. This study investigates the Ni-, Co-, V-, and Pt-enriched Dilli manganese deposit (Kemaliye-Erzincan, Eastern Türkiye) to constrain the mineralogical, geochemical, and genetic controls on critical metal enrichment in Mn oxide mineralization. An integrated approach combining field observations, petrography, X-ray diffraction (XRD), whole-rock geochemistry, mineral chemistry, and stable C-O isotope analysis was applied to better understand the potential origin of critical mineral enrichments. The mineralization is dominated by Mn4+-bearing oxides, principally pyrolusite and hollandite, accompanied by minor rhodochrosite. High MnO (39-64 wt%) and very low Al2O3 and Fe2O3 contents indicate chemical precipitation with negligible detrital input. Discrimination diagrams and trace-element systematics consistently support a structurally controlled hydrothermal origin. Chondrite-normalized REE patterns display low total REE and very low Nd contents comparable to typical hydrothermal deposits, whereas neutral to slightly positive Ce anomalies and non-chondritic Y/Ho ratios suggest limited oxidative interaction with surface-derived fluids rather than primary marine hydrogenetic growth. Stable C–O isotope compositions of co-genetic calcite are inconsistent with a purely marine depositional environment and indicate precipitation from low-to moderate-temperature hydrothermal fluids. Mineral chemistry reveals strong phase-specific partitioning: hollandite preferentially incorporates V and Ba, whereas pyrolusite is enriched in Ni. Cobalt occurs in both phases, whereas Pt may also be present in both Mn oxide phases, suggesting that trace-element distribution is influenced by both crystallochemical and physicochemical controls. The enrichment of Ni, Co, and Pt is most plausibly linked to hydrothermal fluid circulation through ultramafic units, which likely acted as the primary metal source prior to precipitation. The Dilli deposit thus represents a structurally controlled hydrothermal Mn system enriched in critical metals, emphasizing the exploration relevance of Mn oxide mineral chemistry in identifying alternative sources of critical metals in Türkiye.

Durmus, Hasan; Özkul, İskender; Güler, Ömer; Güler, Seval Hale; Baykal, Duygu Sen; ALMisned, Ghada; Tekin, H.O.
In this study, a novel high-entropy rare-earth tungstate, (PrEuYLaSm)2(WO4)3, was synthesized by high-energy ball milling followed by calcination, and its structural, microstructural, thermal, gamma-ray, and neutron shielding properties were systematically investigated. X-ray diffraction results revealed that ball milling induced partial amorphization of the initial oxide mixture, while calcination at 1100 °C promoted the formation of a single-phase monoclinic A2W3O12-type structure without detectable secondary phases. SEM-EDS mapping showed the homogeneous distribution of Pr, Eu, Y, La, Sm, W, and O throughout the synthesized material. Differential thermal analysis showed sequential desorption, crystallization, and structural ordering processes, together with the absence of sharp decomposition up to 1100 °C, indicating good thermal stability. Radiation shielding evaluation demonstrated that the synthesized high-entropy tungstate exhibited strong gamma-ray attenuation performance, with high mass attenuation coefficient values, low half-value layer values, and stable effective atomic number behaviour over a wide photon energy range. Although some individual oxides showed superior performance at specific energies, the high-entropy composition provided a more balanced shielding response overall. In neutron shielding, the material showed competitive fast neutron removal capability among oxide systems. It can be concluded that the multifunctional potential of (PrEuYLaSm)2(WO4)3 for competitive high-temperature and radiation shielding applications.

Kayaokay, İlyas
This article examines how the French Christian poet Charles Vernay (1842–1866) engaged with Ottoman Sufi poetic discourse in his Divan-ı Verne (1858), a collection of poems written in Ottoman Turkish and Persian. While openly preserving his Christian identity, Vernay frequently employs key Sufi concepts, including ‘tevhid’ (divine unity), ‘aşk-ı hakiki’ (mystical love), ‘irfan’ (gnosis), ‘hakikat’ (truth) and the ‘tarik’ (spiritual path). Through a close textual analysis of selected poems, this study explores the relationship between Vernay’s Christian identity and the Sufi vocabulary that shapes his poetic imagination. The findings demonstrate that Vernay’s use of Sufi terminology extends beyond conventional imitation of classical Ottoman poetry. He employs these concepts to articulate his own spiritual worldview while simultaneously referring to the Bible, Jesus Christ and the doctrine of the Trinity. Although Vernay adopts the metaphysical language of Ottoman Sufism, he does not reproduce its Prophet Muhammad-centred framework. Instead, he reinterprets Sufi concepts within a Christian religious horizon and constructs a spiritual discourse shaped by unity, love, truth and faith. Divan-ı Verne thus reveals how Ottoman Sufi poetic language could be appropriated across religious boundaries and provides new insight into intercultural literary exchange in the nineteenth-century Ottoman world.
- MakaleYalnız künye2026Scopus SJRQ1Exogenous methyl jasmonate delays quality loss and maintains bioactive compounds in quince during long-term storage
Hanci, Mehmet Utku; Ozturk, Ahmet; Aglar, Erdal; Olcer, Mehmet Ali; Ozturk, Burhan
Quince (Cydonia oblonga Mill.) is a climacteric fruit species that, despite its high nutritional value and rich phenolic composition, is prone to quality changes during postharvest handling. However, under appropriate storage conditions it can be maintained at acceptable quality for several months. This study aimed to assess the effects of exogenous methyl jasmonate (MeJA) treatments on quality attributes, and phenolic metabolism of quince fruit during cold storage. Fruits were treated with 0 (control), 0.5, and 1.0 mM MeJA and stored at 0 ± 1 °C with 90 ± 5% relative humidity for 120 days. Analyses were conducted at 30-day intervals, including physiological, phytochemical, and antioxidant activity, as well as individual phenolic compounds. During cold storage, fruits treated with 1.0 mM methyl jasmonate (MeJA) exhibited lower weight loss and respiration rate. Higher fruit firmness was also observed in MeJA-treated fruits. At the end of storage, MeJA-treated fruits showed higher vitamin C content and titratable acidity, but lower soluble solids content than the control fruits. Similarly, at 60 and 90 days of storage, fruits treated with 1.0 mM MeJA were found to contain higher levels of total phenolics, total flavonoids, and antioxidant activity. Among the phenolic acids identified in quince fruit, chlorogenic acid and 4-aminobenzoic acid were present at higher concentrations compared to the other phenolic compounds. At the end of the storage, MeJA-treated fruits generally exhibited a slower decline in phenolic acids compared to the control, indicating a protective effect of the treatment on phenolic stability. As a result, methyl jasmonate applications were identified as an effective strategy for reducing post-harvest quality losses and preserving bioactive compounds in quince fruit. Specifically, the 1.0 mM MeJA application showed the strongest protective effect on quality parameters. These findings indicate that MeJA is a commercially viable method for extending shelf life and preserving quality in quince fruit.

Gencer, Burak; Dogan, Gurkan
The diversity of devices in the Internet of Medical Things (IoMT) and Internet of Health Things (IoHT) networks creates significant security vulnerabilities against cyberattacks. Traditional centralized machine learning approaches, however, are not always suitable for these environments due to data privacy regulations. In this study, a new Deep Convolutional Neural Network (DCNN) architecture is proposed for attack detection in IoMT/IoHT networks. The proposed architecture integrates the Residual Squeeze-and-Excitation (RSE) Block, the Squeeze-and-Excitation attention mechanism (SEM), and a one-dimensional multi-pooling approach. The model was evaluated within a federated learning (FL) framework called Federated Medical Intrusion Detection System (FedMedIDS), which preserves data privacy and demonstrates robustness in heterogeneous client scenarios. Four different training strategies—Centralized, FedAvg, FedProx, and Local-Only—were adopted for the evaluations. The proposed model and existing models were tested on the Canadian Institute for Cybersecurity – Internet of Medical Things 2024 (CICIoMT2024) and Edith Cowan University – Internet of Health Things (ECU-IoHT) datasets and compared with current deep learning models. The DCNN proposed for the CICIoMT2024 dataset and a Dirichlet distribution with α = 1.0 achieved F1 scores of up to 99.92% under FedAvg and 94.64% under FedProx with α = 0.5. At α = 0.05, the highest level of heterogeneity, it outperformed the Long Short-Term Memory (LSTM) by as much as 27%. On the ECU-IoHT dataset, F1 scores of up to 89.57% under FedAvg and 89.50% under FedProx were achieved at α = 1.0. This represents an improvement of up to 37% over LSTM at the same level of heterogeneity.

Boylu, F.; Obuz Teker, Gülsen; Ersever Angur, Gafure; Ozdemir, O.; Çelik, M.S.
In this study, a more sustainable, cost-effective, and environmentally friendly approach for selective lithium extraction via water leach assisted by planetary mill mechanical activation was applied on clayey wastes of the Kırka Boron Plant. A detailed systematic study on wastes was performed to optimize both mechanical activation and leaching conditions and to characterize the active powders by XRD, FTIR and EDS/EDX. The results show that lithium can be recovered at relatively low leach temperatures of 50–60°C and short leach times of 3–5 min, achieving leach recoveries of 44.71 (without salt addition) and 57.71% (with 20% salt addition, w/w) without the need for pre-concentration of the waste. Despite relatively low lithium recoveries, water leaching of activated powder produced remarkably low concentrations of co-leached ionic impurities less than 10 ppm Mg, 20 ppm Ca, and 250 ppm K, compared to significantly higher concentrations observed during 1 M acid leaching (9422 ppm Mg, 564.5 Ca, and 72.5 ppm K, upon 1 M acid leaching, respectively). The presence of Mg ions, in particular, is known to be highly detrimental competing ion in metal recovery processes. Therefore, the proposed method offers both economic and environmental advantages by enabling higher purity lithium recovery under much milder conditions.

Yardımcı, Uğurcan; Tuğan, Volkan
In this study, a novel liquid cooled battery thermal management system integrated with a thermoelectric assisted cooling channel has been designed. To prevent battery cells from operating at high temperatures and to ensure a uniform temperature distribution among the cells, multiple thermoelectric stations were placed at various positions along the cooling channel. The performance of four different models created with various temperature combinations, as well as a conventional model without thermoelectrics, was investigated through Computational Fluid Dynamics simulations. In the analyses, five different thermoelectric temperatures (293.15–298.15 K), two different mass flow rates (0.0013 and 0.0018 kg/s), and two different initial temperatures (298.15 and 303.15 K) were examined. The results demonstrated a significant improvement in the performance of the battery thermal management system with the use of the thermoelectric assisted cooling channel. It was determined that lowering the initial temperature from 303.15 K to 298.15 K and increasing the mass flow rate from 0.0013 kg/s to 0.0018 kg/s resulted in better cooling performance and more uniform distribution for the thermoelectric assisted system. Under the conditions of a 0.0013 kg/s mass flow rate and an initial temperature of 303.15 K, the highest reduction in maximum battery temperature, compared to the non-thermoelectric design, was achieved in Model B with 9.207 K. Under the same conditions, the most significant reduction in maximum temperature difference was observed in Model D with 4.758 K. Furthermore, the Root Mean Square Spread analysis results revealed that Model B provided the best performance in terms of temperature distribution.

Durmus, Hasan; Kilic, Gökhan; Ilik, E.; Kavaz, Erkan; Güler, Ömer; Birdoğan, Selcuk; Almisned, Ghada; Tekin, Hüseyin Ozan
This study presents a systematic investigation of lithium borotellurite glasses reinforced with nano-Eu2O3, with the aim to enhance the structural stability and radiation shielding performance. Glasses were synthesized with Eu2O3 concentrations from 0 to 10 mol % and characterized through density, X-ray diffraction, and transmission electron microscopy. The results showed that the density increased steadily from 4.030 to 4.734 g/cm3 with the Eu addition, while the molar volume also expanded, indicating that the incorporation of larger Eu3+ ions induced network expansion alongside densification. The X-ray diffraction patterns showed amorphous structures for all the compositions except Eu(n)2, which exhibited local crystallinity, later suppressed at higher Eu levels. The transmission electron microscopy pictures and energy dispersive spectroscopy mapping showed homogeneous nanoparticle distribution without clustering. Gamma-ray attenuation studies demonstrated clear improvements with Eu doping: the linear attenuation coefficient increased from 8.33 cm−1 (Eu(n)0) to 12.42 cm−1 (Eu(n)10) at 81 keV, while the half-value layer values decreased, confirming superior low-energy absorption. Experimental neutron studies revealed ΣR values comparable to standard neutron moderators, with Eu(n)10 showing a favorable balance of gamma and neutron shielding. Limitations include the restricted photon energy window and single neutron source. Future work should extend testing to higher energies, thermal/epithermal neutron ranges, and mechanical and durability assessments. Overall, nano-Eu2O3 reinforcement provides a promising pathway toward multifunctional transparent shielding glasses.

Güler, Ömer; Güler, Seval Hale; Özkul, İskender; Baykal, Duygu Sen; Tekin, H.O.; ALMisned, Ghada
A spinel-structured high-entropy alloy-oxide (HEAO) with the nominal composition (Fe30Cr30Mn20Ni10V10)3O4 was synthesized via mechanical alloying followed by thermo-mechanical oxidation X-ray diffraction indicated the formation of a predominantly spinel-type cubic oxide phase after oxidation, with the observed reflections being consistent with the Fd-3m spinel structure, while SEM-EDS mapping showed a homogeneous cation distribution at the examined scale. XPS analysis revealed mixed valence states of Fe2+/Fe3+, Cr3+/Cr4+, Mn3+/Mn4+, Ni2+/Ni3+, and V4+/V5+. Thermodynamic parameters supported phase stability, with ΔSmix = 12.51 J K−1·mol−1 and Ω = 2.68. Gamma-ray attenuation properties were evaluated over 0.015-15 MeV. The linear attenuation coefficient decreased from 193.685 cm−1 at 0.015 MeV to 0.309 cm−1 at 1 MeV and stabilized near 0.137 cm−1 at 15 MeV. Correspondingly, the half value layer increased from 0.004 cm to 5.068 cm across the same energy range. The effective atomic number decreased from 24.58 at 0.015 MeV to approximately 15.37 at 1 MeV, followed by a moderate increase to 17.71 at 15 MeV. Comparative analysis with commercial stainless steel, titanium alloys, nickel-based superalloys, ferro-boron systems, and lightweight entropy alloys demonstrated that the synthesized HEAO exhibits intermediate yet stable attenuation performance, positioning it between low-density Al-based systems and high-density Ni-rich alloys. It can be concluded that the alloy-to-oxide strategy enables the production of a structurally stable spinel HEAO with consistent and competitive gamma-ray attenuation behaviour across a broad photon energy spectrum.

Polat, Erkan
Concrete-filled composite plate shear walls (C-PSW/CF) are an emerging prefabricated structural system that combines high strength, stiffness, and constructability for use in high-rise and seismic applications. Conventional plastic-theory-based flexural models originally developed for planar walls are intended only to estimate peak flexural strength; however, they cannot adequately capture several mechanisms governing the behavior of C-shaped sections, including concrete confinement, plate local buckling, von Mises stress interaction, and shear-lag effects. Moreover, no analytical formulations are currently available for predicting the full monotonic flexural response of such walls. This study develops a surrogate-based modeling framework that integrates high-fidelity finite element (FE) simulations with Response Surface Methodology (RSM) to predict the monotonic flexural response and yield moment capacity of C-shaped C-PSW/CF walls. A validated three-dimensional FE model (FEM) was used to simulate 77 wall configurations generated through a Central Composite Design (CCD) by varying six geometric and material parameters. Second-order RSM equations were derived to estimate moment capacity across drift ratios up to ±4% in both loading directions and to predict yield moments corresponding to the onset of web and flange plate yielding. The developed models show high predictive accuracy (R² > 0.95) and successfully capture nonlinear parameter interactions among section geometry, reinforcement ratio, and steel yield strength. Compared with nonlinear FE simulations, the RSM equations enable rapid prediction of wall capacity using explicit closed-form expressions, providing a computationally efficient tool for performance-based design and parametric evaluation of prefabricated composite wall systems.

Background Children with Down syndrome (DS) often have feeding problems, which may negatively affect the quality of life (QoL) of their parents. This study aimed to identify feeding problems in children with DS and to examine the relationship between these feeding problems and parental QoL. Methods This cross-sectional study included 105 parents of children aged 10–18 years with DS in Turkey. Data were collected through face-to-face interviews using the Screening Tool of Feeding Problems (STEP) and the SF-36 Health Survey (SF-36). Results This study indicated that the mean STEP scale scores were below the average level across all frequency × severity subscales. Parents' mean scores on the SF-36 QoL scale were above the reference mean (x̄ = 50.00) for the physical functioning, vitality, mental health, social functioning, pain, and general health perception subscales, whereas scores for the physical role limitation and emotional role limitation subscales were below the reference mean. In this study, a moderate negative correlation was found between STEP subscale scores and parents' mean SF-36 subscale scores ( p ≤ 0.05). Conclusions In this study, a significant negative correlation was found between the STEP subscale scores and the parents' mean SF-36 subscale scores. Implications to practice: Routine feeding assessments using the STEP scale should be conducted for children with DS, and nurse-led parent education programs addressing feeding problems should be implemented.

Özdemir, Osman; Yücel, Halit Lutfi; Kahraman, Gökhan
This study experimentally investigates the use of several passive cooling techniques to enhance the electrical performance of photovoltaic (PV) modules under high ambient summer temperatures in Elazığ, Turkey. Throughout the trial period of July, August, and September, a system comprising four photovoltaic panels, one designated as a reference, was developed. The first passive cooling arrangement utilized a paraffin-based phase change material (PCM) RT42HC. In the second configuration, a nano-enhanced PCM (NePCM) composite was employed, prepared by dispersing 1 mass% of Al2O3 nanoparticles into the paraffin matrix and stabilizing them with 3 mass% of sodium dodecyl sulfate (SDS) to ensure homogeneous distribution. The third, hybrid configuration integrated 14 graphene-coated parabolic pin-tipped fins mounted externally onto the aluminum enclosure housing the NePCM composite. Experimental results demonstrated that the implemented passive cooling techniques markedly decreased the panel surface temperature, thereby enhancing electrical power output and photovoltaic efficiency. The hybrid graphene-coated fin-NePCM system demonstrated superior performance, achieving a maximum surface temperature reduction of 12.65 °C, a sustained electrical efficiency increase of 6–13%, and an average daily electrical energy gain of 26.23 Wh day−1 compared to the reference module. These findings demonstrate that the integrated hybrid design is an effective and reliable passive cooling method for sustaining photovoltaic system performance under hot climate conditions.

The demand for sustainable construction materials promotes the use of industrial waste in cement-based systems. This study examines mortars incorporating fly ash (FA) (0%, 7.5%, and 15%), waste glass, and chromite aggregates for mechanical and durability performance. Specimens underwent compressive strength, freeze–thaw, high-temperature, sulfate attack, and ultrasonic pulse velocity tests, while microstructure was characterized by x-ray diffraction, thermogravimetric analysis, and scanning electron microscopy–energy-dispersive spectroscopy. Mortars with 7.5% FA exhibited relatively high compressive strength and improved freeze–thaw resistance. The combined use of chromite and FA improved strength retention at 800°C, reaching 23 MPa with 7.5% FA and 50% chromite. The greatest sulfate resistance occurred in mortars containing 15% FA and 15% waste glass, maintaining compressive strengths of 61 and 70.9 MPa after MgSO4 and Na2SO4 exposure, respectively.

Anesthesia practices in aquaculture are important for preventing potential stress in fish. For this purpose, interest in natural anesthetic agents as substitute for currently used synthetic anesthetics has increased. In this context, the present study demonstrated the anesthetic efficacy of citronella oil (Cymbopogon nardus) in rainbow trout (Oncorhynchus mykiss) individuals. Based on an artificial neural network (ANN) model derived from preliminary studies, the optimal anesthetic concentration for rainbow trout individuals was estimated as 90 μL L−1. Validation of the concentration predicted by ANN revealed no time-dependent hematological or histological effects on fish to citronella oil. Furthermore, biochemical tests revealed that the partial post-anesthesia increase in ALT and AST values was transient and negligible in light of histological findings. Although oxidative stress was observed during the acute period, the enzymatic activity of SOD and CAT effectively reduced the oxidative damage, demonstrating their role in protecting the fish from oxidative stress. The antioxidant activity observed was temporary, returning to baseline levels without any accompanying tissue damage at the tested concentration. Behavioral monitoring further indicated a swift reduction in motor activity followed by a smooth recovery process, with no evident signs of stress or avoidance behaviour. Overall, these results position citronella oil as a promising natural anesthetic for rainbow trout under the studied parameters. That said, further studies involving various solvents, temperature ranges, and fish species are necessary to comprehensively establish its efficacy and safety.

Topcuoğlu, Ceyhun; Ozel, Alp; Tutun Yumin, Eylem; Sertel, Meral; Tug, Tuncer
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is associated with respiratory muscle dysfunction, postural alterations and balance impairment. However, the impact of respiratory muscle weakness on postural control and its relationship with spinal curvature and mobility remain insufficiently clarified. OBJECTIVES: The objectives of this study were to compare postural control in individuals with COPD with and without respiratory muscle weakness; to examine the relationship among spinal curvature, spinal mobility, postural control and respiratory muscle strength; and to determine the effect of respiratory muscle strength on postural control. METHODS: This cross-sectional study included 41 clinically stable individuals with COPD aged 40–75 years. Respiratory muscle strength was assessed using a mouth pressure measurement device. Postural control and balance were evaluated with the Biodex Balance System and functional tests. Higher stability index values indicate greater postural sway and poorer balance performance, whereas lower values reflect better postural stability. Spinal curvature and mobility were assessed using the Spinal Mouse®. RESULTS: Individuals with respiratory muscle weakness showed significantly higher overall, anterior–posterior and medial–lateral stability indices, as well as worse eyes-open and eyes-closed firm-surface indices compared to those without weakness (p < 0.05). In participants with severe and very severe COPD, thoracic kyphosis angle was significantly associated with MIP, MIP% and multiple balance indices under different surface and visual conditions (p < 0.05). CONCLUSIONS: Respiratory muscle weakness is associated with impaired postural control and balance performance in individuals with COPD, and thoracic spinal curvature appears to be linked to both respiratory muscle strength and balance outcomes.

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.

Özpolat, Gürhan; Tural, Ali Can
Robin George Collingwood, tarihsel bilginin dinamik ve öznel doğasını kabul ederek, doğa bilimlerinden farklı bir tarihsel metodolojinin gerekliliğini vurgulamıştır. Onun felsefesi, tüm insanlık tarihinin temelde insan düşüncesinin ve öz farkındalığının tarihi olduğunu ileri sürer. Collingwood, tarihsel aktörlerin düşüncelerini ve niyetlerini yakalama çabasında, geçmiş olayların “dışı” ve “içi” arasında ayrım yapar. Ona göre, tarihçinin rolü sadece olayları kaydetmenin ötesine geçer; ilgili soruları formüle ederek geçmiş düşünceleri zihinsel olarak yeniden canlandırmayı içerir. Bu makale, Collingwood'un felsefesinin tarihsel kavrayış üzerindeki derin etkisini, özellikle de “soru ve cevap mantığı” olarak bilinen yaklaşımı aracılığıyla incelemektedir. Bu yöntem, tarihsel anlayışın temeli olarak sorular ve cevaplar arasındaki etkileşimin altını çizmektedir. Soru ve cevap mantığı, önermeler ve sorular arasındaki karmaşık bağı vurgulayarak geleneksel mantığa meydan okur ve böylece tarihsel sorgulamada anlam, hakikat ve anlayışı yeniden tanımlar. Ayrıca makale, bu yaklaşımı hermenötik gelenek içerisinde analiz ederek, anlamanın süregelen ve sonsuz doğasını ele almaktadır. Heidegger'in döngüsel hermenötik anlayışıyla paralellikler kurarak, tarihsel yorumlamanın ve tarihsel anlam arayışının dinamik, diyalektik ve diyalojik doğasını vurgulamaktadır. Özetle, bu çalışma Collingwood'un çağdaş hermenötik üzerindeki etkisini incelemekte ve tarihsel yorumlama ve insan anlayışında soru ve cevap mantığının geçerliliğini yeniden teyit etmektedir.

Çalışma kapsamında sürdürülebilir tüketim davranışlarının demografik değişkenlerle ilgisi de araştırılmaktadır. Bu doğrultuda Munzur Üniversitesi Aktuluk kampüsünde öğrenim gören ve kolayda örnekleme yöntemiyle seçilen 485 öğrenciden yüz yüze anket yöntemiyle toplanılan veriler, SPSS-21 istatistiki programı kullanılarak analiz edilmiştir. Çalışmada elde edilen bulgular, üniversite öğrencilerinin sürdürülebilir tüketim davranışları sergileme düzeylerinin; yaş demografik faktörü açısından bir farklılık göstermediğini, evli öğrencilerin; bekar öğrencilere göre, lisansüstü öğrenim düzeyine sahip öğrencilerin; ön lisans öğrenim düzeyine sahip öğrencilere göre daha yüksek çevre duyarlılığı ve tasarruf davranışı düzeyine sahip olduklarını göstermektedir. Çalışma, elde edilen bulgular dahilinde, üniversite öğrencilerini sürdürülebilir tüketim davranışına yöneltmek isteyen kurumlara yönelik önerilere yer vermektedir. Çalışma içinde yer alan sonuç ve öneriler, kurumlara geliştirecekleri stratejilerde kullanabilecekleri veriler sağlayabileceği gibi üniversitelere sürdürülebilir kampüs ortamları yaratabilme noktasında da yol gösterici fikirler sunabilecektir.

İncele - MakaleYalnız künye2025Güncel sanat pratiğinde ev mekânının performatif bir alan olarak heterotopik kurgusu
Baltürk, Betül Buldak
Temelde bir mimarlık nesnesi olan ev, insanı temel alan disiplinler tarafından yapısal niteliğinin yanı sıra hem kültürel hem de fenomenolojik boyutuyla, tarihsel/ güncel bağlamları içinde çokça tartışılan bir niteliğe sahiptir. Günümüz sanatında birbirinden farklı konu ve pratik alan etrafında şekillenen örnekler olarak karşımıza çıkan ev kavramı, bu araştırmada yer verilen sanat yapıtlarından hareketle heterotopya kavramıyla bağlantılı olarak yorumlanmıştır. Fransız düşünür Michel Foucault tarafından geliştirilen heterotopya kavramı, mekânla ilişkili bir kavram olarak bir mekânın içinde barındırdığı farklı unsurların ilişkiselliği temelinden okunmaktadır. Bizlere çok boyutlu bir mekân okuması sunan kavram, araştırma kapsamında ev imgesine yönelik sanat üretim pratikleriyle birlikte ele alınırken nesne, mekân ve kişiler arasında aktif bir iletişimin yer aldığı güncel sanat örneklerine yer verilmiştir. Bu anlamda günümüz sanatçılarından Olivia Erlanger, Alex Da Corte ve Volkan Aslan’ın video ve performans gibi pratiklerin bir arada kullanıldığı üç boyutlu ev-mekân düzenlemeleri, heterotopya kavramının iç içe geçmiş farklı mekânsallıklara açılan yapısı bakımından incelenmiştir.
