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.

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.

Şenel Tekin, Perihan; Bekar, Fevziye
The aim of this book chapter is to lay the concepts of sustainable development, ecological footprint, carbon footprint, permaculture and biomimicry, which are thought to complement one another and serve almost the same purpose, on the basis of proactive behaviors. Sustainable development means balancing ecological, social, and economic dimensions and meeting the needs of the present without consuming the resources of future generations. The ecological footprint is an indicator of sustainable development and involves calculations relevant to the world’s energy consumption, capacity and overall biomass efficiency. A carbon footprint is a type of ecological footprint, while biomimicry involves the emulation of nature to create pathways for crafting innovative designs. The discipline of permaculture derives from permanent culture and agriculture and concerns about creating sustainable living spaces. In this regard, sustainability may be ensured with the inclusion of proactive mindsets as opposed to reactive perspectives to facilitate individual ownership of sustainability within social lifestyles and business environments.

Recepoğlu, Mürşit; Hayaloğlu, Pınar; Cakir, Sümeyra Cay; Artan, Seyfettin; Cakir, Mehmet Ali
The surge in the global population over the past century has highlighted the importance of agricultural production, leading to many studies to boost productivity. Unlike previous studies that primarily explore agricultural productivity growth, this study investigates how the subcomponents of the ecological footprint affect agricultural productivity in MENA countries between 1992 and 2021, identifying which types of environmental pollution have the most significant impact. Driscoll and Kraay (1998) method results show that ecological footprint has a major negative impact on agricultural productivity. Similarly, all ecological footprint components have a negative impact on agricultural productivity. The forest footprint has the highest coefficient magnitude, followed by crop land footprint, carbon footprint, fishing grounds footprint and grazing land footprint. The results have been tested for robustness using the Half-Panel Jackknife test to avoid biased results, and parallel results have been obtained. Finally, the causality between agricultural productivity and explanatory variables has been tested using Dumitrescu and Hurlin (2012) panel causality test. The findings suggest that policymakers may find it more effective to eliminate pollution rather than using additional resources to increase agricultural productivity. This approach allows for the reallocation of resources used in agricultural production to other areas.

Ediz, Çiçek; Uzun, Sevda
Objective: This study aimed to explore the metaphorical perceptions and cognitive structures of Turkish nursing students related to the impact of the global climate crisis on their profession. Methods: Researchers adopted a qualitative approach centered on metaphor analysis and involved 40 Turkish nursing students enrolled in programs in Türkiye during October 2023. Using metaphor analysis and techniques involving writing and drawing, the study uncovered how these students perceive and cognitively structure the influence of the global climate crisis on their nursing careers. The interview form featured the metaphor expression “The reflection of the global climate crisis on nursing is like … because …,” while the drawing component prompted students to determine their perspectives on the climate crisis's impact on nursing through concept drawings. The research adhered to the COREQ checklist. Results: The study revealed that nursing students generated 22 metaphors each through written and drawing techniques. Written metaphors were grouped into five categories: psychosocial challenges faced by nurses, patient populations, diseases and coping, burdens on the health system, and the growing importance of various fields within nursing. Drawing technique metaphors were grouped into four categories: nurses and the difficulties they face, the impact of the global climate crisis on the world, the impact of the global climate crisis on the healthcare sector, and the roles and responsibilities of nurses. Conclusions: While nursing students expressed diverse opinions, their concerns about the reflection of the global climate crisis on nursing yielded similar emotional responses. Metaphors are mostly focused on psychosocial challenges faced by nurses, the patient population, diseases, and coping mechanisms. The findings underscored nursing students’ concerns about the global climate crisis's impact on both their profession and the broader community.

Öztürk, Kaşif Furkan
Natural gas pipelines are important infrastructure elements that are often designed to be buried and can cross very long distances, both on the mainland and on the ocean seabed. In this context, researches on the safety of these structures, which are known to cause significant economic losses if damaged, still maintains its importance. From this point of view, the dynamic behavior of a buried pipe system modeled using the equivalent spring-dashpot approach is investigated for three different soil systems and two earthquake records with three different frequency contents. The research shows that while the peak von mises stress of the pipe system can generally decrease depending on decrease in soil stiffness, the peak lateral displacements of the pipe system can generally increase depending on the decrease in soil stiffness. Furthermore, the results point out that the peak von mises stresses and the lateral displacements of the pipe system can significantly increase from high frequency content to low frequency content depending on the frequency content of earthquake.

Purba, Tumian Lian Daya; Karimullah, Suud Sarim; Palit, Silvester Magnus Loogman
This study comprehensively examines how existing environmental policies often exacerbate social inequality and neglect the rights of vulnerable communities, particularly minorities, indigenous peoples, and those living below the poverty line. This study adopts a library research method, exploring the concept of eco-apartheid and its implications for human rights through an integrated literature review, combined with a content analysis approach. The results of this study confirm that eco-apartheid reflects structural injustices that violate human rights, particularly the right to a clean and healthy environment. Land grabbing, exploitation of natural resources, and urban segregation widen ecological and social inequalities, which are exacerbated by weak law enforcement and the dominance of corporate interests. The right to a decent and healthy environment has been recognised in international law proceedings, such as UN Resolution No. 76/300 of 2022, the 1972 Stockholm Declaration, and the 1992 Rio Declaration. In the ASEAN region, exclusive development has marginalised poor communities and reinforced eco-apartheid, necessitating a new legal paradigm that places the environment as a subject of human rights protection, with the application of various principles of precaution and vigilance, transparent policy reform, and protection for environmental defenders. Ecologically, just legal excellence is critical for eliminating eco-apartheid and guaranteeing every individual's right to a safe, fair, and sustainable environment.

Cakir, Mehmet Ali; Unlu, Ramazan; Cakir, Sümeyra Cay; Xanthopoulos, Petros
This study assesses the future of clean energy and technology access for cooking in emerging economic blocs—BRICS, MINT, ASEAN, and MENA—through 2030. Cooking contributes 3% of global greenhouse gas emissions, with over half of household emissions coming from cooking. Therefore, clean cooking energy is critical for sustainability and human health. The study aims to evaluate the likelihood of achieving the UN Sustainable Development Goal of universal clean cooking energy access by 2030 and the 2050 net-zero emissions target. Machine learning techniques, such as support vector regression, gradient boosting, and linear regression, alongside an ensemble approach, provide forecasts for these regions. The findings show a varied outlook. Within ASEAN, two countries are expected to reach 100% clean energy access for cooking by 2030, while two are likely to experience a decline. The MENA region shows stronger progress, with eight countries expected to meet the 2030 target. Among BRICS countries, only India is projected to reach full accessibility, while Russia faces a decline. The MINT countries face challenges, with none expected to meet the target, and Nigeria is projected to experience a decrease in clean energy access. The study concludes that the current trajectory makes achieving the 2030 Sustainable Development Goals and the 2050 net-zero emissions target unlikely for these regions. Policymakers must reassess their strategies and learn from successful countries to improve outcomes.

Açikel, S.; Cumhur, I.; Öztürk, A.; Başoğlu, M.; Düzgün, I.
This work systematically examines the influence of partial substitution of calcium (Ca) by erbium (Er) on the structural integrity and superconducting performance of Bi2Sr2Ca2Cu3O10+δ (BSCCO) high-temperature superconductors. Samples were synthesized through the conventional solid-state reaction method and characterized via X-ray diffraction, scanning electron microscopy, resistivity, and magnetization measurements. Despite the close effective ionic radii of Er and Ca, experimental results revealed that increasing Er content led to a deterioration of the superconducting phase and the emergence of semicon ducting characteristics. Quantitative analyses demonstrated a notable reduction in critical current density (Jc), with undoped BSCCO samples exhibiting approximately 14% higher Jc values under equivalent conditions. These findings suggest that while ionic size considerations may permit Er substitution from a stoichiometric perspective, the structural and superconducting phase stability of the BSCCO matrix is adversely affected by Er incorporation.

Aim: This study aimed to evaluate the psychometric characteristics of the Turkish version of the “Stress Scale for Siblings of Childhood Cancer Patients (SCCP)”. Methods: This study was conducted with 273 siblings aged 11-16 of childhood cancer patients (SCCPs) who were treated in a hospital in the Black Sea Region of Türkiye between March 2022 and April 2024. Data were collected with “The Sociodemographic Information Form” and “SCCP”. The data were examined through descriptive statistics, as well as exploratory and confirmatory factor analyzes. Results: The SCCP Turkish version is a valid and reliable scale consisting of 27 items and six sub-dimensions. The SCCP Turkish version explained 77.676% of the total variance. The SCCP Turkish version was found to be summable according to Tukey's test of additivity (p = 0.334), and the test-retest reliability of the scale was r = 0.864 (p < 0.05). Conclusion: This study indicate that the Turkish version of the SCCP is a valid and reliable instrument for evaluating stress levels in siblings aged 11 to 16. Practice Implications: With SCCP, nurses can determine the stress levels of SCCPs and contribute to the planning of necessary interventions to cope with stress.

The primary aim of this study is to adapt the Self-Regulation of Eating Behavior Questionnaire (SREBQ) to the Turkish culture among young women nurses and nursing students. The secondary aim is to investigate the factors associated with self-regulation of eating behavior in this population. The sample consisted of 773 young women nurses and nursing students who were included in the study between June and July 2024. In accordance with the first aim of the study, the construct validity of the SREBQ instrument was confirmed through EFA. The Cronbach's alpha coefficient for the SREBQ was found to be 0.78. There were very low positive correlations between the SREBQ score and the SRS (r = 0.252) and TREQ-CR (r = 0.136) scores, as well as low negative correlations with the TREQ-EE (r = −0.355) and TREQ-UE (r = −0.406) scores (p < 0.001). The 5-item SREBQ has been found to be a valid and reliable instrument for the population of young women nurses and nursing students in the Turkish language. The results indicate that as self-regulation of eating behavior increases in this population, overall self-regulation skills improve, while disordered eating behaviors decrease.

Gürmeriç, Hüseyin Ender; Basaran, Burhan
In this study, data from 17 studies reporting the presence of microplastics in milk and dairy products in the literature were examined with a product-based systematic approach. In addition, geographical comparisons were made between different countries. In milk and dairy products, the concentration of microplastics has been reported to exhibit a broad range, extending from non-detectable levels to as high as 10,040 MPs per kilogram, contingent upon the specific product types. Milk powder (especially baby milk powder) stands out as the riskiest product group in terms of microplastic content. Although the sizes and colors of the detected microplastics vary significantly, the fiber form is generally predominant. While polyethylene, polypropylene, polyamide and polyester are among the polymers frequently detected, high-temperature-resistant industrial polymers such as polytetrafluoroethylene, polysulfone, polyurethane were also encountered. In addition, the presence of some polymers (such polyvinyl chloride, polyurethane) that are toxicologically risky for human health was reported in the studies. In addition, the study evaluated the chemical, enzymatic and physical methods used for the separation and identification of MPs; the advantages and limitations of FT-IR, Raman and other analysis techniques were revealed. This study reveals that MP contamination in milk and dairy products is a multidimensional problem. The findings show that milk and dairy products are highly susceptible to plastic contamination at every stage of production.

Erdoğdu, Aylin; Dayi, Faruk; Özbek, Adem; Ganji, Farshad; Benek, Ayhan
This study offers a comprehensive analysis of the performance and systemic dynamics of green finance investments in environmentally sustainable technologies from 2000 to 2025, complemented by scenario-based projections extending to 2050. Empirical results indicate a consistent increase in portfolio returns—from 5.2% in 2000 to 11.8% in 2025—accompanied by a significant reduction in annualized volatility, declining from 8.1% to 3.0%. Concurrently, the portfolio’s sustainability score improved from 0.45 to a full alignment score of 1.00, reflecting a strategic shift towards high-impact green assets. Building on these observed trends, this study introduces the Eco-Financial Resonance Theory (EFRT), an original conceptual framework that interprets sustainable transitions as emergent phenomena arising from resonant interactions among four interdependent domains: financial flows, technological innovation, policy and regulation, and environmental outcomes. Scenario analyses highlight the pivotal roles of policy ambition and innovation pathways in shaping long-term risk-return profiles, with optimistic forecasts projecting returns exceeding 40% by 2050, alongside markedly reduced risks. Regional analysis reveals persistent disparities, underscoring the necessity for context-specific strategies to enhance systemic coherence. Beyond its theoretical contributions, EFRT offers actionable insights for investors and policymakers aiming to align profitability with ecological sustainability. Collectively, these findings position green finance not merely as a niche or ancillary activity but as a transformative mechanism for enabling scalable and resilient sustainability transitions amid accelerating global environmental challenges.

Objective: This study examines the effect of risk perception and socio-demographic and obstetric factors on the level of decision-making of pregnant women via the internet. Method: This study employed a cross-sectional and analytical design and was conducted online with 384 pregnant women living in Turkey. Data were collected using descriptive information forms, such as the decision-making scale via the internet on pregnancy and the perception of pregnancy risk scale. Descriptive statistics, including percentages and means, as well as multiple linear regression analysis, were utilized to analyze the data. Results: As the risk perception in pregnancy increased, the level of decision-making via the internet increased (β=0.118, p=0.000). Among pregnant women experiencing pregnancy-related health issues, a significant increase in decision-making via the internet was observed (β=0.092, p=0.046). As the age of women increased (β=-2.623, p=0.013) and income was perceived to be equal to expenses (β=-1.499, p=0.011) or more than expenses (β=-1.953, p=0.023), decision-making via the internet during pregnancy decreased. Unwanted pregnancy has a “reducing” effect of approximately two times on online decision-making (β=-1.919, p=0.026). The number of pregnancies, education and family type were found to have no statistical effect on decision-making (p>0.05). Conclusion: As the risk perception increases in pregnant women, online decision-making also increases. Factors such as some socio-demographic and obstetric factors affect online decision-making of pregnant women.

Background and Objectives: The study aims to evaluate the effects of regular physical activity on ocular structures by comparing eye anterior segment structures and retinal nerve fiber layer (RNFL) parameters between elite individual athletes and sedentary persons. Materials and Methods: This cross-sectional observational study included 75 participants (33 female and 42 male) aged 18–32 years. Participants consisted of 33 elite individual athletes (66 eyes) aged 18–32 years and 42 sedentary individuals (84 eyes) aged 18–28 years. The elite athlete group consisted of participants who had trained ≥ 3 times per week for the past 5 years and had competition experience in tennis (n = 11), badminton (n = 8), and short/middle distance running (n = 14). Sedentary participants had not engaged in regular physical activity for the last 2 years. Anterior segment structures were measured with ultrasound biomicroscopy (UBM), RNFL parameters were measured with spectral-domain optical coherence tomography (SD-OCT), and intraocular pressure (IOP) was measured with a non-contact pneumotonometer. Results: When the anterior segment parameters were compared, a significance was found in the group effect (p = 0.021, (Formula presented.) = 0.036) in the TIA500 value, but the effects of side and gender were insignificant (p > 0.05). While the gender effect was found to be significant for the AOD500 (p = 0.030, (Formula presented.) = 0.032) and ARA500 (p = 0.019, (Formula presented.) = 0.038) variables, the group and side effects were statistically insignificant (p > 0.05). There was a significant difference in IOP values between sedentary individuals (15.82 ± 2.69) and athletes (14.61 ± 1.80) (p = 0.004, (Formula presented.) = 0.057). There was a significant difference between the right (15.71 ± 2.70) and left (14.87 ± 2.02) sides (p = 0.027, (Formula presented.) = 0.033). The effect of gender was not significant (p > 0.05). When the results were evaluated, a significant effect of the TEMPORAL side in RNFL parameters (p = 0.003, (Formula presented.) = 0.058) was observed. Correlations were seen between the anterior segment and RNFL parameters in both groups (p < 0.05). Conclusions: Athletes exhibited lower IOP compared with sedentary individuals, with similar RNFL parameters but distinct correlation patterns with anterior segment structures. These findings suggest that ocular parameters should be evaluated in an integrated manner and that physical activity may support ocular health by contributing to IOP reduction and potentially slowing the progression of eye diseases.

Erkan, Ilker; Alp, Ibrahim
This study investigated the effects of NaOH direct leaching for sulfur removal from a kaolin ore from the Balıkesir region, Turkey. Characterization studies were undertaken before sulfur removal studies to enlighten the structure and originate the source of sulfur. The characterization studies revealed that the ore was mainly composed of quartz, with sulfur originating from alunite minerals with opal inclusions. The leaching process was tested under varying NaOH concentrations (1.5–2 M), temperatures (95 ± 2°C), and durations (2 h) in temperature-controlled closed systems to maintain consistency. Results demonstrated complete (100%) sulfur removal from alunite under optimal conditions. However, significant mass losses (18.15%–45%) occurred because of the dissolution of kaolinite along with alunite, indicating the method's effectiveness in sulfur removal but also its potential drawbacks for kaolinite retention.

Background: Nutritional habits are a critical factor influencing the performance and recovery of professional athletes. Understanding how demographic variables affect nutrition-related attitudes is essential for developing targeted interventions. Objective: This study examined the nutritional attitudes of professional female volleyball players in Türkiye based on various demographic characteristics. Methods: The study included 386 licensed female volleyball players from the Turkish Women's Volleyball Super League, First League, and Second League. Data were collected using a demographic questionnaire and the Attitude Scale for Healthy Nutrition. Normality was assessed using the Kolmogorov-Smirnov test and skewness-kurtosis values. Statistical analyses included t-tests, ANOVA, LSD post-hoc tests, and partial correlation. Results: Significant differences in nutritional attitudes were found based on league level, smoking status, years of experience, and income level (p < 0.01). No significant differences were observed based on education level. Among the sub-dimensions, the malnutrition component showed no significant differences across most variables. Super League athletes scored significantly higher in nutritional knowledge and positive nutritional behaviors. Conclusion: The nutritional attitudes of professional volleyball players vary considerably according to key demographic factors. These findings highlight the importance of targeted nutrition education, particularly for lower-league athletes, to enhance performance and reduce disparities in nutritional knowledge.

In today's world, where young adults face increasing psychological and social challenges, understanding the factors that influence loneliness has become more critical than ever. This study examines whether perceived self-efficacy mediates the relationship between parental acceptance and loneliness in university students. The study population consists of undergraduate students studying at universities affiliated with the Council of Higher Education in Türkiye. Data were collected with demographic information form created by the researchers, UCLA Loneliness Scale, Adult Parental Acceptance-Rejection Scale, Coping Self-Efficacy Scale. Independent samples t-test and one-way analysis of variance were used for comparisons between groups, and Pearson's correlation analysis and mediation analysis were used to analyze the relationships between variables. According to the results, the level of acceptance perceived by male students from their mothers was higher than that of female students. There is a significant negative relationship exists between loneliness levels and parental acceptance of university students. It was found that parental acceptance scores significantly predicted loneliness and coping self-efficacy scores. This study shows that self-efficacy has a partial mediating role in the relationship between parental acceptance and loneliness and that self-efficacy may create resistance against negative emotions. Identifying this relationship and potential mediating effects at an early stage is important for strengthening the family environment and promoting healthy child development. This study will contribute to the literature with new findings to identify protective factors and develop psychosocial interventions for young adults struggling with loneliness.
