Sirat, Abdulveli
Maize is an important short day cereal with a wide range of uses as a raw material in human and animal nutrition industry. This study was conducted during 2016 and 2017 to identify grain yield and some quality characteristics of dent corn genotypes under semi-arid temperate climate conditions. Twelve (12) dent corn genotypes were utilized as plant material in the study. The research was carried out according to the randomized complete blocks experimental design with three replications. Significant differences were recorded between the genotypes in terms of all traits (except cob length). The plant height ranged 197.90-211.25 cm, with first cob height of 81.24-107.30 cm, cob length of 17.02-19.10 cm, cob diameter of 39.82-50.82 mm, number of kernels per cob of 423.77-590.82, and grain yield of 4650.0-10693.9 kg ha(-1). It was noted that the 1000-grain weight varied between 254.96-348.93 g, hectoliter weight with range of 79.06-89.83 kg hl(-1), starch content in grain between 62.59-69.50%, protein content in grain between 9.22-11.74%, oil content in grain between 2.67-3.98%. The maximum values of plant height and cob length were obtained from the 70May82 variety, and the maximum values of first cob height, cob diameter, grain yield, 1000-kernel weight, hectoliter weight, starch, protein, and oil content in grain were recorded from Kalipso and Samada-07 varieties. Considering these results, it is advisable to grow Kalipso, Samada-07, and 70 May82 varieties as main crops in temperate semi-arid climate of G & uuml;m & uuml;& scedil;hane and surrounding areas of Turkiye.

Merdan, Mehmet; Aydemir, Hilal
PurposeThe purpose of this study is to develop and apply the Elzaki-Homotopy Analysis Method (EHAM) as an efficient analytical technique for solving fractional-order partial differential equations (PDEs). By integrating the Elzaki transformation with the homotopy analysis framework, the study aims to obtain accurate and convergent analytical solutions for nonlinear and random fractional PDEs. Additionally, it seeks to evaluate the influence of stochastic parameters, where coefficients or initial conditions follow various probability distributions. The research further aims to compute the variance, expected value, and confidence intervals of the solutions and visualize the outcomes using MATLAB software.Design/methodology/approachIn this study, the Elzaki-Homotopy Analysis Method (EHAM) is employed by combining the Elzaki transformation with the homotopy analysis method to construct analytical solutions for fractional-order partial differential equations. The local fractional derivative is utilized to handle non-integer order behavior effectively. The proposed approach is applied to both linear and nonlinear equations under random conditions, where initial parameters and coefficients follow uniform, beta, normal, and gamma distributions. Statistical measures such as variance, expected value, and confidence intervals are calculated to analyze solution behavior. All computations and graphical representations are performed using MATLAB (2013a) to verify the method's accuracy and convergence.FindingsThe findings of this study demonstrate that the Elzaki-Homotopy Analysis Method (EHAM) provides highly accurate and rapidly convergent analytical solutions for fractional-order partial differential equations. The method effectively handles both linear and nonlinear problems involving random parameters. Statistical analysis of the obtained solutions reveals that the expected values and variances remain stable across different probability distributions, confirming the robustness of the approach. The convergence region can be easily controlled through the auxiliary parameters of the homotopy method. Comparisons with numerical results validate the reliability and efficiency of EHAM, establishing it as a powerful alternative to conventional numerical and perturbation techniques.Originality/valueThis study presents an innovative analytical framework for solving fractional-order partial differential equations using the Elzaki-Homotopy Analysis Method (EHAM). By integrating the Elzaki transformation with the homotopy analysis approach, the method efficiently addresses the complexities of nonlinear and stochastic systems. The inclusion of random variables with different probability distributions enhances the model's applicability to real-world phenomena. Analytical solutions are systematically derived, and their statistical properties-such as variance, expected value, and confidence intervals-are examined. Implemented through MATLAB (2013a), the results confirm EHAM's strong convergence, reliability, and computational efficiency, positioning it as a superior alternative to traditional numerical techniques.

Yalcin, Numan; Dedeturk, Mutlu
In this study, we develop a systematic framework for anageometric calculus as an extension of non-Newtonian analysis. Fundamental concepts, including limits, continuity, differentiation, and higher order derivatives, are established, and the connection to classical calculus is clarified through a logarithmic transformation. Within this framework, we derive the properties of the anageometric derivative, inverse function relations, partial derivatives, and mean value theorems. The theory is extended to integration by establishing the first and second fundamental theorems of anageometric calculus. Furthermore, the structural implications of the anageometric derivative are investigated, demonstrating that the equation D similar to f=lambda f naturally generates power-law solutions rather than classical exponential ones. This highlights the suitability of anageometric analysis for scale-invariant phenomena and proportional growth processes, supported by a practical heat-conduction example.

Aydin, Aydanur
In the event of a natural disaster, women who assume multiple roles within the family unit tend to postpone their health concerns and delay medical appointments. The present study aims to examine the relationship between the level of fear of breast cancer and the implementation of breast cancer preventive behaviours among women following an earthquake. The sample consists of 2,671 women aged 20 and over who participated voluntarily. The data were collected using two instruments: the Breast Cancer Fear Scale and the Women's Breast Cancer Prevention Behaviors Form. Following a comprehensive review of the extant literature, it was determined that women affected by earthquakes exhibited elevated levels of fear of breast cancer. A substantial decline was observed in the utilization of preventive measures necessitating institutional access, including mammography. The findings of this study indicate that education, occupation, and family history of breast cancer have a significant impact on women's post-earthquake fear levels in implementing preventive behaviours. However, given the cross-sectional design and the absence of pre-disaster baseline data, these findings reflect post-earthquake associations rather than temporal or causal trends. Natural disasters can result in the deterioration of health perceptions, exacerbated by heightened stress and health concerns. Consequently, there is an urgent need for innovative approaches to ensure the maintenance of health check-ups and continuous access to preventive care in the aftermath of large-scale natural disasters.

Berktas, Serap
This study aimed to investigate the effects of dietary fibers obtained from cold-pressing by-products on the bioactivity of Spirulina (SP) during in vitro digestion. For this purpose, insoluble dietary fibers (CCDL and KCDL) were extracted from cold-pressing by-products of flaxseed and black cumin. SP was combined with CCDL and KCDL, and subjected to an in vitro digestion protocol (INFOGEST). The results showed that the total phenolic content of SP decreased after oral and gastric digestion with the addition of dietary fiber. After small intestinal digestion, the total phenolic content increased. Antioxidant activity values (DPPH and ABTS) decreased in the presence of dietary fiber, while chlorophyll values increased after small intestinal digestion. In particular, in the presence of CCDL, the chlorophyll content increased from 1.61 mg g(-1) to 4.48 mg 2 g(-1) after small intestinal digestion. Furthermore, the bioactivity values of SP after in vitro digestion varied depending on the type of dietary fiber. While KCDL was effective in increasing phenolic compound content, CCDL was more effective in increasing chlorophyll content. Considering the bioactivity values of SP after oral, gastric, and small intestinal digestion, it was determined that the values increased especially in the small intestine. This highlights the possibility that the bioaccessibility and therefore the bioavailability, of SP can be increased through the incorporation of dietary fiber. The addition of bioactive compounds to the development of functional foods rich in dietary fiber has advantages for the food industry in terms of designing and improving healthy foods. This study emphasizes that the in vitro digestion of Spirulina is regulated in the presence of CCDL and KCDL, and that the addition of dietary fibers may contribute to the potential health benefits of Spirulina.

Denizli, Umut
This study examines the ethical implications ofcontemporary digital technologies for human existence, focusing on the semiotic construction of human-machine interaction in the anthology series Black Mirror. The research gap addressed in this article concerns the limited attention paid to the sign systems through which the series produces ethical meanings: while existing studies have discussed BlackMirror mainly as a thematic critique of technological dystopia, fewer have systematically examined how visual and verbal signs organise questions of consciousness, autonomy, surveillance, identity, and responsibility. To address this gap, the study uses a Saussurean and Peircean semiotic framework to analyse how selected episodes encode ethical problems at the intersection of organic and artificial life. The empirical corpus consists of fourteen purposively selected episodes from seasons 2-6, excluding the later seventh season released in 2025, and was examined through qualitative coding of visual and verbal signs related to consciousness transfer, artificial intelligence (AI), social media, virtual reality, surveillance, and digital vigilantism. The analysis identifies recurring oppositions between embodiment and disembodiment, autonomy and control, presence and mediation, and responsibility and outsourcing, which together articulate specific moral narratives about technological progress. The articles' original contribution lies in linking semiotic form to technological ethics: it shows how popular techno-dystopian fiction not only represents ethical problems thematically but also constructs them through recurring signs, oppositions, motifs, and narrative patterns. The findings suggest that Black Mirror foregrounds the fragility of human agency in technologically mediated environments and problematises unregulated innovation as a threat to dignity, privacy, and social cohesion within the selected corpus. The study concludes that these findings are interpretive insights from a purposively selected corpus, while also indicating the need for further research on how AI and related technologies are represented, governed, and ethically implemented in ways that protect human agency, dignity, and the broader public interest.
- MakaleAçık Erişim2026Examination of Health-Seeking Behavior in Individuals with Chronic Diseases
Cosar, Dilan Aktepe; Demirag, Hatice; Cin, Aynur
Background: Chronic illnesses are long-term, noncommunicable diseases that significantly affect daily life. In addition to physical symptoms, they can reduce quality of life by causing psychological effects such as anxiety and depression. Patients often seek health information to better manage their condition. Methods: This study aimed to examine the level of health information-seeking behavior among individuals with chronic diseases and the factors influencing this behavior. The sample group for this descriptive study consisted of 306 individuals with chronic illnesses who visited X Hospital in northeastern T & uuml;rkiye between April 1, 2024, and February 1, 2025. All individuals completed a questionnaire consisting of the Patient Information Form and the Health Seeking Behavior Scale. Results: The sociodemographic characteristics of patients with chronic diseases, such as education level, marital status, and chronic disease duration, significantly affected the health-seeking behavior scores. According to the research findings, the highest mean score was determined as 12.30 +/- 2.62 in the occupational health-seeking subdimension, whereas the lowest mean score was determined as 8.78 +/- 3.83 (min-max: 3-15) in the traditional health-seeking subdimension. The total mean score of the Health Seeking Behavior Scale was 32.2 7 +/- 7.73. Conclusions: Individuals with chronic illnesses tend to prefer professional health care services when seeking health-related behaviors. Health-seeking behaviors were higher among high school graduates, single individuals, and those without chronic illnesses.

Öztürk, Umit; Yalçin, Seda
It is possible to say that Plato's texts are heavily intertwined with mythological elements or narratives. One of the main reasons for this fact can be found that the characters in the dialogues are constructed in a way that vividly conveys the spirit of the period. However, some terms or concepts that were present in the cultural atmosphere of the period and in the vocabulary of every philosopher writing at that time make the understanding of the texts extremely difficult, especially when the metaphorical contexts are taken into account. Among such concepts, there are daimonion and daim & omacr;n and their grammatical derivatives, which are extremely difficult to translate into different languages. Moreover, when the last-mentioned concepts are being connected with the terms such as theos and its derivatives, which altogether can be considered to be in the same semantic family, it becomes even more difficult to understand some Platonic texts. This article primarily aims to analytically distinguish between the daimonion and daim & omacr;n narratives in the Apology and the Symposium. Secondly, via referring to other Platonic texts, the question of whether these concepts can be understood on common ground is discussed.

Top, Yener; Sönmez, Gulen
Micro-scale enterprises contribute to the economies of the countries they are located in, such as employment generation, rural development, and providing training opportunities for semi-skilled workers. They constitute the majority of enterprises in terms of number, but their share in the production rate is low. Furniture manufacturing is one of the sub-branches of the main manufacturing industry, and the majority of the enterprises that produce furniture are micro-scale. These enterprises face several challenges. One of these challenges is that a significant portion of their employees have not received any formal vocational training. The communication opportunities and tools (such as social media) of our time have made it easier to access information. This has made informal education possible for those who have not received a formal vocational training or have received it but want to improve themselves. In this study, the use of social media in the vocational development of employees of micro-scale enterprises manufacturing furniture was investigated. With this objective, a structured survey was conducted face-to-face with 110 participants in the central district of Trabzon to adequately represent the target population. To analyze the data, frequency tables, Spearman Correlation Analysis, Kolmogorov-Smirnov Normality, Kruskal-Wallis, Mann-Whitney U and Chi-Squared Tests were used. The findings indicate that a significant majority of the employees are aged between 25 and 54, with 47.2 % lacking any vocational training. Furthermore, substantial differences were observed in the employees' use of social media for vocational development purposes, correlated with their age and educational level.

Çalik, Erdogan Serdar
This article examines Augustine's understanding of knowledge not merely as a theoretical acquisition but as a moral process that transforms the human being. The first section of the study addresses the foundations of Augustine's epistemology, discussing the connection between knowledge, happiness, and wisdom, as well as the ethical dimension of knowledge and its role in the transformation of the soul. Furthermore, the epistemological role of memory and time is evaluated as dynamics that enable the pursuit of truth. The second section analyzes the influence of Augustinian epistemology during the scholastic period. In this context, Anselm's faith-based approach, Bonaventure's mystical interpretation, and Thomas Aquinas' Aristotelian synthesis are examined, with a focus on the nominalist critiques beginning with William of Ockham. The conclusion states that Augustine's epistemology presents a unique and enduring model that grounds the source of knowledge in inner enlightenment and its purpose in virtuous living, thus concluding the study.

Demir, Habip
Purpose: This study aims to examine how the official ideological discourse in Iran is produced through the educational curriculum and how Sunni Islam is positioned within this institutional discourse. In this context, our study examines how Sunni Islam is represented in the Ma`& amacr;rif-i Isl & amacr;m & imacr;: V & imacr;je-yi Ahl al-Sunnat textbooks prepared for Sunni students at the primary education level in Iran, and through which discursive strategies this representation is constructed. Considering the determining influence of Twelver Shi'ism- the official sect of the Islamic Republic of Iran-on state institutions and the educational system, the way Sunnism is defined in institutional texts emerges as a significant subject of scholarly inquiry. In this context, the study seeks to demonstrate that sectarian identities are produced not only through doctrinal differences but also through institutional discourse and educational materials. The central research problem of the study is to identify the concepts, historical references, and narratives through which the Sunni sect is represented within Iran's official educational system. Method: The study was designed within the framework of a qualitative research approach. The data source for the study consists of the elective textbooks titled Ma`& amacr;rif-i Isl & amacr;m & imacr;: V & imacr;jeyi Ahl al-Sunnat prepared for Sunni students by the Iranian Ministry of Education as a supplement to the mandatory textbooks for elementary school (grades 2-6) and middle school (grades 7-9). A total of 8 textbooks were subjected to document analysis in this study; the books were examined holistically, and the texts, activities, and visual narratives were evaluated thematically using a discourse analysis approach. Findings: The findings reveal that Sunni identity in the examined textbooks is represented through several recurring thematic frameworks. In sections related to ritual practices, the practices of Sunni legal schools are explained in detail, enabling Sunni students to learn the religious practices associated with their own tradition. At the same time, the selection of historical figures largely avoids controversial personalities that could potentially generate sectarian tensions; instead, the textbooks highlight companions and scholars who are respected to some extent in both Sunni and Shi'i traditions. Furthermore, narratives concerning the Ahl al-Bayt and the event of Karbala are presented both as shared religious references and as significant elements of Shi'i historical discourse. The treatment of concepts such as taqlid, mujtahid, and religious leadership also indicates that these textbooks function not merely as pedagogical materials but as texts that carry ideological meanings associated with the political and ideological discourse of the Iranian state. Conclusion: The study concludes that the textbooks prepared for Sunni students in Iran constitute important institutional texts that demonstrate how sectarian identity is represented at the institutional level. Within these texts, Sunni identity is recognized and made visible to a certain extent; however, it is simultaneously redefined within a discursive framework compatible with the official Shi'i ideological structure. In this regard, the research contributes to the literature in the field of History of Islamic Sects by demonstrating how sectarian identities are produced and represented through educational materials. Moreover, the findings contribute to contemporary discussions on the relationship between sectarian identity and education, while also indicating new directions for future research on similar institutional texts.

Aksut, Yavuz Selim; Yetgín, Sukru
In this study, ground blast furnace slag (GBFS) and waste volcanic rock dust (RD) produced in a natural stone processing plant were used as binders. The binders were activated with Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) to produce two types of concrete: alkali-activated concrete without fibers (AAC) and alkali-activated concrete with fibers (FAAC). In the production of concrete, steel and polyester fibers were used separately and hybrid at 0.25%, 0.50%, 0.75% and 1.0% by volume and a total of 117 15x15x15 cm cube specimens were produced. The mechanical properties of the specimens were evaluated by concrete surface hardness, ultrasonic pulse velocity and concrete compressive strength tests at 3, 7 and 28 days. The results obtained using non-destructive test methods were matched with concrete compressive strength values using various empirical formulas. Calculated concrete compressive strength values and actual concrete compressive strength values were compared using data analysis method. As a result, it was observed that there was a very significant correlation between the experimental compressive strength and the combined method in which 7-day surface hardness and ultrasound transmission rate were used together to calculate the compressive strength.

Üzülmez, Mehmet
This study evaluates land use patterns in reclaimed coastal areas of Ortahisar district, Trabzon, from 2000 to 2024. It examines the role, functions, and environmental and structural impacts of reclamation in urban development. In mountainous cities like Trabzon, with limited flat land, sea filling is a key urban expansion strategy. The research combines literature review, satellite image analysis, and GIS mapping (ArcGIS), supported by climate, population, and topographic data from official sources. The study analyses reclaimed zones including Akyaz & imath;, Be & scedil;irli, Ganita, and De & gbreve;irmendere. InAkyaz & imath;, 39 hectares serve the & Scedil;enol G & uuml;ne & scedil;Sports Complex, and 29 hectares serve the city hospital ,which is currently under construction, alongside a mosque, fishermen's shelter, and parking. Ganita includes 17 hectares of parks and recreation and 9 hectares for transport infrastructure, reflecting a public-use planning approach. De & gbreve;irmendere hosts parks, fishermen's shelters, roads, a port, and breakwaters, with about 28 hectares unused. These areas address population growth and land scarcity, creating new urban spaces but posing environmental and engineering risks. International studies highlight issues such as ground settlement, structural instability, flood and storm vulnerability, and marine ecosystem damage in reclaimed lands. While valuable for infrastructure and public services, reclamation should be managed beyond spatial growth. The study stresses how multifunctional, public-focused, strategic planning shaped these areas. However, comprehensive interdisciplinary approaches are needed for ground safety, sustainability, and ecosystem protection. Future planning must mandate geotechnical surveys and environmental impact assessments. Reclamation should align with natural processes, not just physical expansion. Public participation and integrating local needs are crucial. Transport and access plans should balance coastal access and sustainability. Ortahisar's reclamations offer short-term urban solutions, but long-term risk reduction requires integrated sustainable planning.

Kaya, Asli Uner
The nature and function of thought experiments, which have become an important part of philosophical and scientific discourse, are among the topics that have been researched with great interest not only by philosophers but also by historians of science, cognitive scientists and psychologists in recent years. Thought experiments, which we can trace back to the Pre-Socratics, are frequently encountered in the Middle Ages, especially in fields such as theology and natural philosophy. Imaginary scenarios designed by important figures in the Islamic world such as Ibn Sina, Ibn al-Haytham and Ghazali provide important information about the way thought experiments were used in the period. Ibn Sina was the first philosopher to try to explain the psychological basis of thought experiments. The fundamental question he focuses on is: What is the source of the premises used in thought experiments? According to Ibn Sina, the source of thought experiments is wahm, an internal, sensory faculty that has no exact English equivalent but is usually translated as estimative faculty. My aim in this article is to focus on the faculty of illusion that Ibn Sina introduced while creating the psychological infrastructure of thought experiments and to reveal the role that this faculty plays in the formation of thought experiments.
- MakaleYalnız künye2026Scopus SJRQ2The lived experience of individual stock investors during decision-making: a phenomenological perspective on investment psychology
Soydas, Safak Sonmez
Purpose - This study explores how individual stock investors experience and interpret their decision-making processes beyond cognitive bias frameworks. It aims to reveal how investment decisions are shaped through cultural memory, moral values, social identity and digital environments, emphasizing the lived meanings investors attribute to risk, gain, and loss. Design/methodology/approach - A qualitative phenomenological design was employed. In-depth semi-structured interviews were conducted with 20 active individual stock investors in T & uuml;rkiye. Data were analyzed using Colaizzi's seven-step phenomenological method to identify the lived meaning structures underlying investment decision experiences. Findings - Investment decisions emerged as multidimensional experiences organized around four interrelated domains: cultural roots and collective economic memory, moral and religious tensions, social status and identity construction, and digitalization with emerging economic perceptions. Participants interpreted risk, gain, and investment outcomes through family narratives, moral and religious evaluations, identity-related concerns, and digitally mediated information environments rather than solely through rational calculations. Research limitations/implications - The findings are based on a limited qualitative sample and therefore cannot be statistically generalized. However, they contribute to a deeper theoretical understanding of investment behaviour by integrating cultural, moral, identity-related, and digital dimensions within a phenomenological behavioural finance perspective. Future research may build on these findings through mixed-method designs and cross-cultural comparisons. Practical implications - The findings support investor education programmes, decision-support systems and behavioural policy design by highlighting the experiential and meaning-based dimensions of investment decision-making. Social implications - The study demonstrates that investment decision-making is shaped by cultural values, moral interpretations, social identity processes and digitally mediated environments, suggesting that financial decisions are socially embedded rather than purely individual or rational. These findings may contribute to more socially sensitive financial literacy initiatives and policy development. Originality/value - This study extends behavioural finance by introducing a phenomenological lived-experience perspective, demonstrating that investment decision-making emerges through interacting cultural, moral, identity-related and digital meaning structures rather than solely through cognitive biases.

Background/objective Psychological well-being disorders are increasingly prevalent among young people. While physical activity is known to benefit psychological well-being, the mechanisms-particularly the role of physical self-perception and gender in recreational context remain underexplored. Grounded in the Conservation of Resources (COR) Theory, this study investigates the mediating role of physical self-perception in the relationship between recreational physical activity and psychological well-being and examines whether gender moderates this mediation among youth aged 15-24.Methods A descriptive-relational survey design was employed. The sample comprised 468 young adults (58.5% male, 41.5% female; M_age = 20.08) who regularly participated in recreational physical activities. Data were collected using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Physical Self-Perception Profile (PSPP), and the Warwick-Edinburgh Mental Well-being Scale (WEMWBS). Mediation and moderation analyses were conducted using PROCESS macro-Models 4 and 7.Results The direct effect of physical activity on psychological well-being was not significant. However, physical self-perception fully mediated the relationship between physical activity and psychological well-being (indirect effect: beta = 0.219, 95% CI [0.151, 0.290]). Among the sub-dimensions of physical self-perception, body attractiveness had the strongest mediating effect. Moderation analysis revealed that gender did not significantly moderate the mediation pathways (a path: p = 0.156; b path: p = 0.954). The mediation mechanism operated with similar strength in both males and females.Conclusion Recreational physical activity improves psychological well-being entirely through the enhancement of physical self-perception, supporting the COR theory that physical activity acts as a resource investment. This mechanism is universal across genders in recreational settings. Interventions aiming to improve youth psychological well-being should not only promote physical activity but specifically focus on fostering positive physical self-perception and body image in inclusive, non-judgmental environments.
