Article Effect of Carob Aqueous Extract on Boron, Copper, Zinc, Iron, and Vitamin C Levels in Brain, Heart, Liver, and Kidney Tissues of Diabetic Wistar Albino Rats(Wiley, 2026-03-29) Basegmez, Mehmet; Eryavuz, Azra Mila; Avsar, Mehmet Talha; Atik, Hulya Demirkapi; Demirel, Hasan Huseyin; Durmus, Ibrahim; Eryavuz, AbdullahThe utilization of medicinal plants in diabetes mellitus treatment is increasing owing to their effectiveness and safety compared to synthetic drugs. Thus, this study aimed to evaluate the effects of the aqueous extract of carob on tissue trace element levels, vitamin C concentrations, and histopathological alterations in streptozotocin-nicotinamide (STZ-NA)-induced diabetic Wistar albino rats. Rats were randomly divided into four experimental groups: control, diabetes, carob, and diabetes + carob. Following diabetes induction, rats in the diabetes + carob group were treated with carob aqueous extract during the experimental period. At the end of the study, tissue samples from the brain, liver, heart, and kidney were collected from rats. The samples were analyzed to determine vitamin C levels as well as trace elements, including boron (B), copper (Cu), zinc (Zn), and iron (Fe). Additionally, histopathological changes in collected tissues were examined. Diabetes significantly reduced vitamin C levels in brain and kidney tissues (p < 0.05), whereas no significant change was observed in the heart and liver (p > 0.05). Carob extract administration significantly increased tissue vitamin C levels in both diabetic and non-diabetic rats (p < 0.05). Additionally, both diabetes and carob aqueous extract administration were found to alter tissue trace mineral composition. In conclusion, the study demonstrates that carob aqueous extract can have an effect on tissue vitamin C and some trace mineral levels in normal and diabetic rats.Article Digital Transformation and the Evolution of Professional Identity: A Qualitative Study on the Perceptions of Office Management and Secretarial Students(Wiley, 2026-01) Ergun; Husnu; Ergün, HüsnüTo date, understanding the future of the office management and secretarial profession, which is rapidly changing under the influence of technology, has consistently been approached through sector-based analyses. This study, however, shifts the perspective to focus on the hearts and minds of the young people preparing for this journey. Using a qualitative approach, the research is aimed at identifying the perceptions of participants by investigating whether they view this digital transformation as a threat or an opportunity and how it affects their career aspirations and professional identities. The participants are students at the department of office management and secretarial studies within a vocational school of a state university. Interviews with a total of 22 participants were analyzed under the themes of productivity and business processes, job security and professional transformation, remote work experience, cybersecurity concerns, and socioethical impacts. The findings indicate that while digital tools (e.g., ERP, cloud systems) increase operational efficiency, digital adaptation requires time. Artificial intelligence and automation are leading to the evolution of traditional roles into titles such as digital assistant coordinator, making proficiency in digital work management tools a necessity. Although remote work initially posed social and technical challenges, productivity was maintained through digital discipline. While cyber risks like data breaches necessitate proactive measures, ethical and social issues have been highlighted, such as the impact of human-machine interaction, the erosion of social bonds, and clients ' need for human contact. The research underscores that digitalization is intertwined with technological, pedagogical, and social dynamics. It is recommended that educational programs be updated to include data analytics, ethical sensitivity, and strategic skills. By examining professional transformation from the student perspective, this study fills a gap in the literature; for future research, the inclusion of quantitative methods and the involvement of industry stakeholders is recommended.Article Comparison of Selected Trace Elements, Oxidative Stress, and Antioxidant Status in Umbilical Cord Blood Plasma from Women in Rural and Urban Areas(Springer Nature, 2026-02-20) Basegmez, Mehmet; Yigit, Ayse Arzu; Basegmez, Elif; Simsek, OzkanThe aim of this study was to compare selected trace element levels in umbilical cord blood plasma of pregnant women residing in rural and urban areas and to investigate the relationship between trace elements and oxidative stress parameters. Umbilical cord blood samples were collected from 50 pregnant women living in rural and urban areas. Total antioxidant status (TAS) and total oxidant status (TOS) in plasma were determined by colorimetric method. Levels of nickel (Ni), manganese (Mn), aluminum (Al), iron (Fe), mercury (Hg), cadmium (Cd), vanadium (V), and selenium (Se) were measured by inductively coupled plasma optical emission spectrometry. Ni, Mn, Al, Fe, Hg, and Cd levels in cord blood plasma were significantly higher in pregnant women residing in rural areas compared to those in urban areas (p < 0.001). In contrast, V and Se concentrations were significantly higher in the urban group (p < 0.001). TAS and TOS levels in umbilical cord blood plasma were also significantly elevated in the rural group. The increased TAS levels observed in pregnant women residing in rural areas may reflect a compensatory and adaptive antioxidant response to elevated oxidative stress, as indicated by higher TOS levels, which may be associated with increased exposure to trace elements. This study provides preliminary data of significant differences in trace element levels, oxidative stress, and antioxidant status in umbilical cord blood plasma collected at delivery from women residing in rural and urban areas. These findings highlight environmental disparities between the two regions and provide a basis for future studies investigating prenatal exposure to trace elements and oxidative stress.Article Autonomy Support and Motivation in Physical Education: A Comparison of Teacher and Student Perspectives(Asya Publishing and Consultancy, 2023-09-27) A., Arik; G., ErturanArticle Performance Comparison of Argos and Iridium Tracking Technologies for Sea Turtle Movement Ecology Studies(MDPI, 2025-12-15) Casale, Paolo; Figgener, Christine; Arendt, Michael; Broderick, Annette C.; Ceriani, Simona A.; Kaska, Yakup; Plotkin, Pamela; Luschi, PaoloSatellite tracking has dramatically improved research on wide-ranging large marine vertebrates such as sea turtles. Traditionally, sea turtle tracking has relied on Argos-based satellite telemetry tags, which estimate location via Doppler shift and can also transmit sensor data. GPS-equipped Argos satellite tags represented a significant evolution, offering higher location accuracy. More recently, GPS-equipped satellite tags transmitting via the Iridium satellite network have become available for sea turtle tracking, and this study aims to assess whether they offer additional advantages. The performance of three satellite tag types-Argos-only, Argos-GPS, and Iridium-GPS (Iridium)-was assessed using data on 116,074 positions from 48 sea turtles representing five species and multiple ocean basins. Performance was evaluated using three indicators: the proportion of days with location data, the duration of gaps between locations, and the number of positions per day. Bayesian generalized linear mixed models assessed the effect of satellite tag type, technical settings, species, and activity (migration, foraging, internesting). Results indicate that Iridium satellite tags generally perform similarly to both Argos-based satellite tags, but performance improves significantly when programmed with high-frequency GPS acquisition (>24 positions/day), a result made possible by their tenfold higher transmission capacity compared to Argos. This capacity also enables transmission of more sensor data. Performance, however, varied by species and activity. These findings highlight the potential of Iridium tags to enhance fine-scale movement studies by improving the spatial and temporal resolution of sea turtle tracking, with important implications for ecological research and conservation planning.Article Two New Records of Oak Gall Wasps (Hymenoptera: Cynipidae) from Türkiye(Gazi Entomological Research Soc, 2025-12-01) Tataroglu, Musa; Katilmis, YusufTwo new records for the Turkish oak gall wasp fauna (Cynipidae: Cynipini) were recorded during a field study conducted in Burdur province, located in southwestern Turkiye. Andricus cryptobius Wachtl, 1880, and Dryocosmus destefanii Cerasa & Melika, 2018, were found for the first time on Quercus trojana Webb, a native oak species that is prevalent in this region. These new records expand the known diversity of cynipid species in Turkiye, enhancing knowledge of the oak gall wasp fauna and extending the known global distribution of these species. Data regarding the occurrence of the recorded species in Turkiye, their global distribution, and host plants are provided.Article Part 1: Cationization of Cotton Terry Towel Fabrics by Exhaustion Method; Labscale and Commercial Scale Trials(Ege Üniversitesi, 2025-10-01) Yildirim, Fatma Filiz; Elibuyuk, Sultan Aras; Avinc, Ozan; Yumru, Saban; Corekcioglu, MustafaThe incompatibility of cotton fibres with numerous dyestuffs can be addressed through the utilisation of considerable quantities of electrolytes. Nevertheless, the extensive utilisation of electrolytes during reactive dyeing inevitably results in the formation of a significant volume of wastewater. To address this challenge, cotton is cationized with cationic agents, thereby enhancing its dyeability with anionic dyestuffs. This study was derived from the findings of a doctoral thesis conducted as a result of a collaborative project between Pamukkale University and Ozanteks Textile Company, a prominent towel and bathrobe manufacturer in Turkey. This research paper consists of two parts. The first part of this reseach paper consist of two sections. In the initial section of this paper, 100% cotton terry towel fabrics were subjected to cationization procedures during and after the bleaching process in a laboratory setting, utilising six distinct commercial cationization agents. Subsequently, the cationized cotton terry towel fabrics were subjected to dyeing processes, namely salt-free reactive dyeing, conventional reactive dyeing, and acid dyeing. The CIELAB values, rubbing and washing fastness, and colour strength (K/S) values of the cotton terry towel fabrics were compared. Subsequently, a decision analysis study (analytical hierarchical process, AHP) was conducted to identify the optimal cationization agent and processes for big commercial-scale applications. The criteria included color strength, colour fastness, and cationic agent cost. In light of the findings of the AHP studies, CA1 coded cationization agent (based on polyammonium compounds) was identified as the optimal cationic agent for utilisation in commercial dyeing, the specifics of which will be outlined in the subsequent paper. Moreover, the findings indicated that cationization should be carried out after bleaching. The second section of the paper presents the results of big commercial scale cationization, reactive and acid dyeings carried out using the selected cationization agent and processes. After commercial scale dyeings, colour strength (K/S) values, physical properties (tensile strength and water absorbency properties) and colour fastness properties (washing fastness, perspiration fastness, water fastness) of cotton terry towel fabrics were analyzed. Furthermore, a comprehensive investigation was conducted into the environmental impacts of cationization and dyeing processes on a commercial scale. This investigation encompassed the analysis of ammonium nitrogen (NH+<inf>4</inf>), chemical oxygen demand (COD) values, overall water usage, chemical consumption, and energy consumption in the context of these dyeing processes. The outcomes showed that, color strength values of salt-free dyeings were close to the conventional dyeings and it is a promising approach for cationization and salt-free dyeing. Additionally, AATC79, EN 14697 and ASTM 4772 test results showed that, salt-free dyeing process had really high absorbency values. Moreover, salt-free dyeing process saved 28% in total chemical consumption, 31% in total water consumption and 16% in total energy consumption when compared to conventional dyeing process. This work demonstrates a promising commercial scale cationization and dyeing process for cotton terry towel fabrics. The second part of the study examined the cationisation of cotton fabrics used for bed sheets — an important home textile product — using the pad-batch method, followed by dyeing. Woven fabrics are generally dyed in open-width form (with the fabric spread out), which is why pad-batch dyeing processes are typically preferred for woven fabrics. In other words, rope dyeing is not commonly used for woven fabrics. Rope dyeing can cause crease marks and uneven dyeing on woven fabrics. Therefore, the first part of the article describes the cationisation and dyeing of towel fabrics using the rope dyeing method (exhaustion), while the second part describes the cationisation and dyeing of bed sheet fabrics using the open-width dyeing method (pad-batch). The CIELAB values, rubbing and washing fastness, and colour fastness (K/S) values of the cotton bed sheet fabrics were statistically compared. © 2025, Ege Universitesi.

For this purpose, two different cheeses were produced, contaminated (CMBP) and not (MBP) with C. sporogenes 73 and C. sporogenes 97 strains, and physicochemical, microbiological and volatile component analyses were performed every 15 days during the 60-day storage period of the cheeses. No significant difference was detected in dry matter (%), fat in dry matter (%), and protein (%) contents of cheeses during storage. As an important finding, C. sporogenes did not affect the acidity values (pH and % acidity). The pH and % acidity values of the cheeses were found to be 4.79±0.03 – 4.98±0.05 and 2.04±0.06 – 2.16±0.06, respectively. When the microbiological results were examined, the total mesophilic aerobic bacteria (TMAB), lactococci and lactobacilli counts of the cheeses decreased during storage, while the yeast-mold counts did not change. There was no change in CMBP cheese with an initial C. sporogenes spore count of 4.62±0.11 during storage. When the color parameters of the cheeses were examined, a difference was detected in the L* value and was lower in CMBP. At the end of storage, there was no change in the a* values of the cheeses, while the b* values decreased. It was determined that there were differences in the aromatic compounds of the cheeses and while the contents of acetic acid, butyric acid and acetoin, which are LBD indicators, were found to be 32.34%, 17.17% and 17.82% in CMBP cheese, butyric acid was not detected in MBP cheese. The results showed that C. sporogenes survived for a long time in white cheeses stored at pH values below 5 and at low temperatures and could cause the LBD on its own.Article Örgütsel Muhalefete Etki Eden Başlatıcı ve Aracı Değişkenler(2021) Celik, Kazim; Ergün, HüsnüBu çalışmanın amacı, “okul çalışanlarının örgütsel bağlılık algılarının örgütsel muhalefeti nasıl etkilediğini ve örgütsel bağlılığın örgütsel muhalefet üzerindeki etkisinde, örgütsel destek ve güvenin aracılık etkisinin olup olmadığının belirlenmesidir”.

This study analyzes the loyalty chain through the service convenience and its influence on different dimensions of perceived value, and their effect on customer satisfaction as a way to achieve the behavior intention, and with it, increase the competitive capacity, management efficiency and economic growth of sports services within the fitness industry. Data from 326 participants were collected using a convenience sampling technique. The data was analyzed using confirmatory factor analysis and covariance-based structural equation modeling (CB-SEM) in Amos (v.22). The results showed that the service convenience has a positive influence on the four dimensions of the perceived value (social value, functional value, emotional value, and economic value). However, only two of these dimensions offered a significant influence on customer satisfaction, with the economic value dimension showing the highest predictive value. Finally, a direct positive effect was found between customer satisfaction and behavioral intention. Therefore, the current study provides a significant sequential pathway between service convenience, economic value, customer satisfaction, and behavioral intention, allowing to improve the understanding of the multidimensionality of the perceived value construct and representing an important contribution to the literature on the fitness industry and to improve the competitiveness of organizations.
