Book Part The Importance of Corporate Social Responsibility Studies in Textile Companies and a Case Study: Ozanteks Tekstil Company’s Corporate Social Responsibility Studies(Springer International Publishing, 2024) Elibüyük, Sultan Aras; Avinc, Ozan; Çörekcioğlu, Mustafa; Yildirim, Fatma Filiz; Öztürk, Serap; Güngör, AşkınerArticle 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 Beneficial Effects of Taurine on 2,3,7,8-Tetrachlorodibenzo-p-Dioxin-Induced Oxidative and Histopathological Damage in the Heart Tissue of Rats(SAGE Publications Inc, 2026-03-23) Çiftçi, Osman; Kaplan, Münevver Nazlıcan; Başak Türkmen, Neşe; Çetin, Aslı; Çiftçi, Bedriye; Ayhan, İdrisThis study investigated the protective effects of taurine against 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-induced cardiotoxic damage in rats. Adult male Wistar rats (250-300 g) were randomly assigned to four groups (n = 8 per group): Control, TCDD, TAU, and TCDD + TAU. TCDD (2 mu g/kg/week) and/or taurine (200 mg/kg/day) were administered via gavage for 30 days. Following the experimental period, heart tissue samples were collected for analysis. Oxidative stress parameters, including thiobarbituric acid reactive substances (TBARS), superoxide dismutase (SOD) activity, and glutathione (GSH) levels, were assessed using biochemical methods. Histopathological and immunohistochemical evaluations of cardiac tissue were also performed. The TCDD group showed significantly increased TBARS levels (p < 0.05) and decreased SOD activity and GSH levels (p < 0.001) compared with the Control group. In contrast, taurine co-administration significantly increased SOD activity and GSH levels while reducing TBARS levels relative to the TCDD group. Moreover, TCDD exposure induced marked histopathological alterations in heart tissue, whereas taurine co-administration attenuated these structural alterations. Immunohistochemical findings indicated that taurine attenuated TCDD-induced apoptosis by reducing caspase-3 activation. Overall, taurine effectively mitigated TCDD-induced oxidative stress, histopathological damage, and apoptotic signaling in cardiac tissue, suggesting that taurine co-administration may exert protective effects against TCDD-induced cardiotoxicity.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 The Trace Element Concentrations in Tissues From the Loggerhead Sea Turtle (Caretta Caretta) From Different Life Stages in Türkiye(Univ. Oradea Publ. House, 2025) Sozbilen, Dogan; Baskale, Eyup; Hol, Aysen; Kaska, Arzu; Divrikli, Umit; Elci, Latif; Kaska, YakupSea turtles can bioaccumulate essential and nonessential trace elements, making them useful bioindicators of the marine ecosystem. We analyzed the 11 trace element concentrations in kidney, liver, and muscle samples (n=175) of stranded loggerhead sea turtles, Caretta caretta (n=70). Our results for Fe, Cu, Zn, and Mn were lower, but Pb, Ni, and Cd levels were higher than those reported in the literature. Given the high levels of loggerhead turtles in specific foraging areas, long-term, concurrent trace element monitoring studies on a larger geographic scale are necessary to understand trace element exposure levels in loggerhead turtle tissues. Conservation of long-lived animals, such as sea turtles, depends on the sustainable monitoring of the pollutants in their environment. Although metal levels were lower than those reported in the literature, we view the Mediterranean Sea as a vast lake into which the 20 countries surrounding it discharge contaminants, and we recommend continuing temporal and spatial monitoring of the impact of pollutants on sea turtles.Article Part 2: Cationization of Cotton Bedsheet Fabrics by Pad-Batch Method(E.u. Printing and Publishing House, 2025) Yildirim, Fatma Filiz; Elibuyuk, Sultan Aras; Avinc, Ozan; Koyuncuoglu, Mehmet Ulan; Yumru, Saban; Aras Elibüyük, SultanCotton is the most widely used fibre in manufacturing, which, being negatively charged, requires various electrolytes to be dyed with negative dyestuffs. These electrolytes cause a large environmental waste water load and unfortunately many of them are released into the environment after waste water treatment. It seems possible to overcome this problem by cationization cotton. This research paper is a two-part study. In the first part of the paper has two sections. 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, utilizing six distinct commercial cationization agents by using exhaustion method. The cationized cotton terry towel fabrics were then subjected to dyeing procedures: salt-free reactive dyeing, conventional reactive dyeing and acid dyeing. The CIELAB values, rubbing and washing fastness, and colour strength (K/S) of the fabrics were then 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, color 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 utilization 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 dyeing's carried out using the selected cationization agent and exhaustion processes. The influence of these processes on the properties of fastness (perspiration, wash, and water fastness) and physical characteristics (tensile strength and water absorption) of cotton terry towel fabrics was evaluated by statistical comparison. The chemical oxygen demand, ammonium nitrogen, total chemical, energy, and water consumption of the commercially available dyes were also compared to assess their environmental impact. The second part of the study examined the cationization of cotton fabrics used for bed sheets - an important home textile product - using the pad-batch method, followed by dyeing. The weaving of fabrics generally occurs in an open-width configuration, wherein the fabric is spread out during the weaving process. This characteristic renders pad-batch dyeing processes particularly well-suited for the treatment of woven fabrics. It may be concluded that rope dyeing is not a common practice when it comes to woven fabrics. Rope dyeing has been observed to result in the formation of crease marks and uneven dyeing on woven fabrics. The first part of the article provides a detailed exposition of the cationization and dyeing of towel fabrics through the utilization of the rope dyeing method (exhaustion). The second part elucidates the cationization and dyeing of bed sheet fabrics employing 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. The statistical analysis indicated that cationic agents and dyeing types exerted a statistically significant effect on K/S. In a similar manner, the quantity of cationic agent had a significant effect on the K/S values. Furthermore, the batching time subsequent to the dyeing process resulted in significant important effect in the K/S values of the fabrics. The factor groups that ensure the colour strength value remains at its optimal (maximum) level are, in order: cationic agent; CA1 coded cationization agent (based on polyamine compounds), cationic agent amount; 5g/l and a waiting (batching) time of 8 hours. In view of the findings, the following conclusions can be drawn with regard to reactive dyeing by pad-batch method: the optimum values in terms of environmental aspects and dyeing can be accepted as 5 g/l of CA1 cationic agent and 8 hours batching.Article 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.
