    Greening Language Learning Pathways: Three Sustainable Practices Using the STAR Framework

    No full text
    Earth is currently facing a multifaceted planetary emergency, primarily due to a lack of fundamental knowledge regarding critical global issues. This situation necessitates the integration of the 17 Sustainable Development Goals (SDGs) established by the United Nations, which are to be achieved by 2030, into educational curricula. Such integration will ensure that future generations develop a comprehensive understanding of emerging threats and assume shared responsibility for sustaining the planet. In this context, language education serves as a foundational means of fostering global awareness. In this paper, the Common European Framework of Reference for Languages is adopted as a guide for pedagogical alignment and language development. Three course plans have been developed for A1, B1, and C1 proficiency levels to raise awareness of sustainability and enhance language competencies. Nature-related themes have been integrated into teaching Turkish as a foreign language using the STAR (Situation, Task, Action, Result) framework. Consequently, learners of Turkish as a foreign language engage with meaningful, real-life contexts that relate to the environmental and climate components of the SDGs. Based on this framework, this study aims to foster both linguistic and ecological literacy through the integration of sustainability themes into foreign language teaching

    Waste of rice hull ash was used during the magnesium silica aerogel production. Magnesium silica aerogel production process optimized by response surface methodology. Flowability behavior in food powder was evaluated by PFT for use as anticaking agent. In vitro and in vivo toxicity studies revealed no toxic effects of magnesium silica aerogels in appropriate doses. The current work presents the findings of production, optimization, and comparative study on chemical, structural, morphological, and water vapor adsorption properties of low-cost water glass-based magnesium silica aerogels (Mg-WG) and eco-friendly rice hull ash-based magnesium silica aerogels (Mg-RHA). The production parameters (Si: Mg molar ratio, feeding time, and aging temperature) of Mg-WG and Mg RHA were optimized using the Box-Behnken Design (BBD) technique combined with Response Surface Methodology (RSM). The optimum product was revealed according to BET surface area (SBET) and water vapor adsorption capacity (WVAC) response variables. Analysis of variance (ANOVA) showed that quadratic model is statistically significant. By optimizing the aging temperature, Si: Mg ratio, and feeding time production parameters of Mg-WG and Mg-RHA, the optimum production conditions are 75 °C and 74.87 °C aging temperature, 1.99 and 1.08 Si: Mg ratio, and 5 min and 7.65 min feeding times were determined respectively. The optimum production conditions of Mg-WG and Mg-RHA were determined as 75 °C and 74.87 °C aging temperature, 1.99 and 1.08 Si: Mg ratio, and 5 min and 7.65 min feeding time, respectively. The effect of Mg silica aerogel added to food powders on the flowability was investigated with a powder flow tester. The results revealed that the use of Mg silica aerogel improved the flow behavior of rock salt and acted as an anti-caking agent. It has been observed that application doses above 50 mg/ml for Mg-WG aerogels and 50 mg/ml and above for Mg-RHA aerogels have a cytotoxic effect on HEK-293 cells and cell viability decreases. Furthermore, it was determined that Mg silica aerogels did not cause any toxic effects in in vitro cytotoxicity and in vivo acute systemic toxicity in appropriate doses.

    İhtiyaçlar arasındaki dengenin sağlanamamasıyla doğal kaynakkayıpları meydana gelmektedir. Hassas ekosistemlerin bozulma ve kayıplarınınnedenlerini analiz ederek sorunlara rasyonel çözümler getirilmesi, planlama veyönetim ile mümkün olmaktadır. Havzalar, bu bozunumlardan etkilenen hassasyüzey birimleridir. Çalışmanın materyalini oluşturan Konya Kapalı Havzası,içerdiği hassas karasal ve akuatik ortamlar ile ekolojik sürecin kesintiyeuğradığı, bozunuma maruz kalan bölge profilindedir. Mevcut planlama modellerineticesinde, havzanın kentsel büyüme odağı içerisinde kalması ve coğrafikarakteristiğine uymayan arazi kullanım kararları sonucunda doğal dengeninbozulması, çalışmanın problemini ifade etmekte ve havzada yeni planlama modeliarayışına sebep olmaktadır. Çalışmada havza ekosistemleri, unsurları vearalarındaki ilişkisel ağ analiz edilmiş; geçmişten günümüze geliştirilenplanlama model ve yaklaşımlarının, kaynak sürdürülebilirliği amacının arkasındakentsel ve ekonomik büyüme kaygısının var olduğu tartışılmıştır. Bu nedenleiçerdiği analiz-sentez süreçleri ve özgün müdahaleleriyle öneri model olan‘Ekolojik Havza Planlama’, havzanın mekânsal planlamasında ekolojik dengenin vekaynak sürdürülebilirliğinin sağlanabilmesi amacıyla, ‘koruma' odağında önerilersunmaktadır. Çalışmanın yöntemini oluşturan bu planlama yaklaşımının uygulamaboyutu ise Konya Kapalı Havzası’dır. Havzada gerçekleştirilen doğal,sosyoekonomik, eşik analizleri ve sentezlerde elde edilen bulgularda;dayanıksız litolojilerde, geçirimli zeminlerde ve jeolojik açıdan risklialanlarda yayılış gösteren coğrafi karakteristiğine uymayan yanlış arazikullanımları tespit edilmiştir. Tarımsal faaliyetlerin büyük ölçekte yeraltısularının kullanılarak yapıldığı havzada, kontrolsüz çekim sonucu suseviyelerinin azaldığı, beraberinde obruk oluşumlarına, akifer tuzlanmalarına,toprak yapısının bozulmasına neden olduğu; sulak alanlara, akarsulara deşarjedilen kirletici unsurların yalnızca hidrolojik döngüyü etkilemediği, devamındatoprak sağlığını, habitatları ve biyoçeşitliliği tehdit ettiği, bulgulararasında incelenmiştir. Planlama yaklaşımının müdahale aracı olan, ‘EkolojikTemelli Master Plan’ ile öneri arazi kullanım kararları getirilmiş, ekolojikdöngünün kesintiye uğradığı bozulmuş alanlarda koruma yaklaşımları ile bozulanarazilerin ekolojik ve estetik değerlerinin yeniden kavuşturulması öngörülmüş;‘koruma’ kavramının temel alınmasıyla uzun süreli perspektiflerdesürdürülebilirliğin mümkün olabileceği vurgulanmıştır.With the growing population, human pressure on theenvironment increases, leading to the loss of natural resources due to theneglect of the conservation-utilization balance and the inability to harmonizeeconomic and ecological needs. Addressing the causes of ecosystem degradationand developing solutions require effective planning and management. Basins, assensitive surface units, are particularly vulnerable to such degradation. TheKonya Closed Basin, the focus of this study, exemplifies a region whereecological processes are disrupted due to unsustainable land use and urbangrowth pressures. Current planning models prioritize urban and economic growthover resource sustainability, exacerbating the basin's ecological imbalance andnecessitating a new planning approach.This study analyzes basin ecosystems,their components, and their interconnected networks, highlighting theshortcomings of past and present planning approaches. To address these issues,the proposed Ecological Basin Planning model emphasizes conservation-focusedplanning. This model integrates analysis and synthesis processes withinnovative interventions aimed at ensuring ecological balance and resourcesustainability in spatial planning. The application of this approach isdemonstrated in the Konya Closed Basin, where natural, socioeconomic, andthreshold analyses reveal significant mismatches between land use and thebasin's geographical characteristics. Unsustainable agricultural practicesreliant on groundwater have caused a decline in water levels, sinkholeformation, soil salinization, and ecological deterioration. Pollutantsdischarged into wetlands and rivers further disrupt the hydrological cycle,threatening soil health, habitats, and biodiversity.The Ecologically BasedMaster Plan, as an intervention tool, proposes land use decisions that alignwith the basin's natural features. It suggests restoring degraded areas byprioritizing conservation to reestablish ecological and aesthetic values.Long-term sustainability, the study concludes, is achievable by makingconservation the foundation of planning efforts, ensuring a balance betweenhuman activity and environmental health.&nbsp;</p

    Phthalocyanines having significant benefits are photosensitizers for photodynamic treatment (PDT) and are at the forefront of PDT applications because of their strong absorption, high photostability, formation of reactive oxygen, selective accumulation, and suitableness for chemical modification and new discoveries necessitate the exploration of additional compounds. This work presents the synthesis, characterization, photochemical, photophysical, and aggregation properties of novel peripheral tetra-substituted Zn(II) (THL-ZnPc) and Mg(II) (THL-MgPc) phthalocyanine derivatives of 4-((4,5-diphenyloxazol-2-yl)thio)phthalonitrile (THL-Pht) as a photosensitizer for PDT applications. Conventional methods were applied for the synthesis of Pc compounds, and spectroscopy techniques such as Ultraviolet and Visible light (UV–Vis), Fourier transform infrared (FT-IR), Nuclear magnetic resonance (NMR), and Matrix-assisted laser desorption/ionization mass (MALDI-TOF MS) spectroscopy were used for characterization. Dimethyl formamide (DMF) and dimethyl sulfoxide (DMSO) solvents were used in order to examine the aggregation behaviors of THL-functionalized phthalocyanines. The photochemical and photophysical characteristics of these phthalocyanines were first studied in DMSO and DMF for the purpose to assess their potential for PDT. The singlet oxygen quantum yield (ΦΔ) values ​​of the compounds were found to be between 0.53–0.68 for THL-ZnPc and 0.41–0.46 for THL-MgPc in different solvents. In conclusion, these phthalocyanines show potential as photosensitizers for PDT investigations based on their singlet oxygen, photodegradation, fluorescence, and aggregation properties
