- MakaleAçık Erişim2025Secondary School Students' Opinions on Teaching the Structure of the Atom with Augmented Reality Application
Gürbüz, Fatih; Sarioglan, Ayberk Bostan
This study is aimed at developing an achievement test on quadrilaterals for seventh-grade students. The concept of the atom can be visualized in different ways in the mind due to its structure, which the naked eye cannot see. Augmented reality (AR) is one of the applications that can be used to teach such concepts. This study aimed to investigate students' views on the use of AR applications in teaching. Phenomenological design, one of the qualitative research designs, was used in the study. The study group consisted of 26 -graders in a public secondary school. AR application was organized to teach the structure of the atom. Within the scope of the study, an interview form consisting of four open-ended questions prepared by the researchers and submitted to expert opinion for content validity was used as a data collection tool. When the students' answers to the questions were examined, it was determined that they had positive opinions that AR application could be used in other courses and different subjects, that this application was more instructive because it concretized the subject, that it caused a better understanding of the subject it was used in, and that it increased participation in the lesson due to the possibilities of providing three-dimensional images. Suggestions were made based on the results.

Background: Extremely low-frequency electromagnetic fields (ELF-EMF) at 50 Hz are prevalent in household electrical systems. Although various studies have examined the effects of ELF-EMF on cell proliferation and gene expression, its impact on amniotic fluid cells (AFCs) remains unclear. Objectives: This study aimed to assess the potential effects of ELF-EMFs on gene expression related to neurogenesis and the Wnt signaling pathway in AFCs. Methods: AFCs were isolated from amniotic fluid obtained via amniocentesis and divided into five groups: control, sham, and three groups exposed to different ELF-EMF intensities (1 mT, 2 mT, 3 mT for 30 minutes/day for 7 days). Expression levels of genes involved in neurogenesis (HES1, Neurog1, Neurog2, Neurod1) and Wnt signaling (SFRP2, SFRP4, SFRP5, APC1) were analyzed using real-time PCR. Results: ELF-EMF exposure did not result in significant changes in gene expression among the experimental groups compared to controls. Conclusion: Short-term exposure (Acute exposure) to ELF-EMF at moderate intensities does not significantly impact gene expression related to neurogenesis or Wnt signaling in AFCs. Future studies should explore prolonged exposure (chronic exposure) and a broader range of intensities to evaluate developmental impacts more comprehensively.

Demirtas, Betul; Yanik, Yusuf; Aymelek, Abdullah; Türker, Temel; Yildirim, Omer
PurposeMinarets, which were constructed from different types of materials, are slender and tall structures. Minarets could vary in terms of the construction technique, geometry and material. The seismic vulnerability and dynamic behavior of minarets could be different because of these reasons. Full-scale evaluation of minarets includes both experimental and numerical investigations. Experimental methods provide knowledge on the in situ conditions. The structural analysis and performance evaluation can be performed by using numerical methods. In this paper, full-scale structural evaluation of the Trabzon Fatih Mosque Minaret was presented by using experimental and numerical methods.Design/methodology/approachFirstly, the finite element (FE) model of the minaret was generated by ANSYS software. Then, experimental measurements were carried out under environmental vibrations with newly developed vibration system. Afterwards, the initial FE model of the minaret was updated by using manual updating method according to the experimental measurement results. For the seismic performance assessment of the historical minaret, the time history and response spectrum analyses were performed on the initial and updated FE models using the acceleration records of 2023 February Kahramanmaras earthquake and TBEC 2018 codes. The results were evaluated comparatively, revealing that the nonlinear analyses produced higher values compared to other methods. Additionally, variations were observed in the updated FE model results compared to the initial FE model. Finally, it was seen that the minaret did not have sufficient strength against Kahramanmaras earthquake load, so it could collapse under such an earthquake.FindingsBy employing model updating method, the average absolute difference was substantially reduced from 9.12% to 2.11%. The maximum displacements increased with the effect of model updating in all analyses. It was also seen that the spectrum analyses results had lower values than the time-history analyses results and the displacement of the updated FE model was found to be approximately 8% greater than that of the initial FE model in the nonlinear analyses. The maximum/minimum principal stresses decreased in the updated model in the linear analyses. Also, it was determined that the equivalent stresses were higher in linear analyses. It was seen that the cracks occurring in the nonlinear analyses were concentrated more intensely at the bottom region, the transition segment and around the balcony of the minaret. The concentration of damage in these regions suggested that special attention was needed to increase structural durability. The drift ratios were calculated as 0.0056 and 0.0076 for the initial and updated FE models in the linear analyses, respectively. The initial FE model remained the CD limit, but the updated model reached the limit in CP. The drift ratios were calculated as 0.0087 and 0.0093 for the initial and updated FE models in the nonlinear analyses. Both the FE models reached the CP limit. It could be concluded that the minaret did not have sufficient strength against Kahramanmaras Earthquake, so it could collapse under such an earthquake. The drift ratios were calculated as 0.0041 and 0.0043 for the initial and updated FE models in the spectrum analyses. Both the FE models remained within the CD limit.Originality/valueThis paper aimed to evaluate effects of FE model updating on the dynamic and seismic behaviors of the historical Fatih Mosque Minaret in Trabzon. Structural behavior of the minaret was investigated using both experimental and numerical methods. For this purpose, 3-D FE model generated with ANSYS software of the minaret was updated according to the ambient vibration test results. Ambient vibration tests were conducted by measurement system, which was developed by our research team. The manual model updating method was utilized to minimize the differences between numerical and experimental results by varying the material properties. The linear-nonlinear time history analyses and response spectrum analyses were carried out to evaluate the seismic performance of the initial and updated FE models using the acceleration records of 2023 February Kahramanmaras Earthquake records and TBEC 2018 codes.

Tanyeri, Levent; Kirkbir, Hakan; Çinan, Ismet; Yilmaz, Busra; Hacicaferoglu, Serkan
Background and Study Aim Material and Methods Mental endurance is considered akeypsychological component that influences athletic performance, particularly in sports that demand high levels of focus and persistence. The aim of the study was to investigate the level of mental endurance in athletes engaged in canoeing. The sample of the study consisted of 163 voluntary canoe athlete students who were studying in the faculties of sport sciences and doing canoeing as licensed students, selected by simple random sampling method. In order to collect the necessary data in the study, the 'Mental Endurance Scale in Sport' was used. The scale consists of the sub-dimensions 'Trust', 'Continuity', and 'Control'. In the analyses of the data, t-test and ANOVA test were used. Statistically, the level of error p<.05 was accepted as Alpha (alpha). Results As a result of the study, it was determined that there was a significant difference in the control sub-dimension according to the gender variable of the students in the sample. It was found that there was a significant difference in terms of age variable. The students aged between 18-20 years were more self-confident, while the students aged between 21-23 years showed more control and continuity. In the sport branch variable, it was found that there was a significant difference in the 'Trust' and 'Control' sub-dimensions, and the effect value was at a moderate level. It was determined that there was a significant difference in the sub-dimension of confidence in the variable of years of doing sports, and the effect value was at a moderate level. The self-confidence of the students who had been doing sports between 1 and 3 years was higher. Conclusions In addition to the physical training and technical skills-enhancing practices of student athletes in sports schools, it will give positive results to carry out actions to increase mental endurance in order to be ready for sportive activities (competitions, recreative activities, etc.). Especially female students or younger students can be less affected by the negativities that may develop instantly within the framework of the difficulties of the sports branch.

Özcan, Serap; Kadakal, Mahir; Iscan, Imdat; Kadakal, Huriye
As researchers, our primary commitment is to engage in the creation of scientific and academic knowledge. Recognizing the importance of societal impact, we also strive to contribute to social awareness through our work. Natural disasters, such as floods, earthquakes, avalanches, landslides, tsunamis, and others, frequently afflict regions globally, resulting in profound human losses and extensive material damage. Notably, the earthquake that struck our country on February 6, 2023, marked as the disaster of the century, deeply affected eleven provinces, leading to a tragic loss of tens of thousands of lives. In this paper, we investigate the concept of earthquake P-functions. We establish the Hermite-Hadamard inequality for this class of functions and derive several refinements of the Hermite-Hadamard type inequality for functions whose first derivative, in absolute value, at a certain power, is an earthquake P-function. We present some applications of the trapezoidal formula. We also provide new bounds for special means of different non-negative real numbers.

Günes, Huseyin; Okutan, Serafettin; Dolanbay, Nihal; Bostanci, Meric Emre
Purpose: This study was conducted to determine the general anxiety and attitudes of surgical nurses toward artificial intelligence. Method: This study was designed as descriptive and correlational with the participation of 335 surgical nurses working in two different hospitals in the Eastern and Central Anatolia regions of Turkey between 06.02.2025-01.06.2025 dates. Results: The scores obtained from the positive and negative attitude sub-dimensions of the General Attitudes towards Artificial Intelligence Scale are moderate (40.24 +/- 8.94, 23.65 +/- 6.61). The total score of the Artificial Intelligence Anxiety Scale is moderate (46.09 +/- 13.65). A low level of negative correlation was found between the positive attitude scores of the General Attitudes towards Artificial Intelligence Scale and the total scores of the Artificial Intelligence Anxiety Scale (r=-0.239, p<0.001). A high level of positive correlation was found between the negative attitude scores of the General Attitudes towards Artificial Intelligence Scale and the total scores of the Artificial Intelligence Anxiety Scale (r=0.710, p<0.001). In the multiple linear regression model established, it was seen that 53% of the anxiety toward artificial intelligence was explained by the general attitudes towards artificial intelligence variable, which is the independent variable in the model (R2=0.530). Conclusion: As the positive attitudes of surgical nurses toward artificial intelligence increase, their anxiety levels toward artificial intelligence decrease. It is necessary to provide continuous education and support to surgical nurses about artificial intelligence applications.

Background. Anaerobic and aerobic power are critical factors influencing peak football performance. This study aimed to explore the differential effects of various high-intensity interval training (HIIT) protocols on these performance metrics in senior female football players. Objectives. The primary objective was to investigate the impact of linear (L) HIIT and change-of-direction (COD) HIIT protocols on key velocity at anaerobic threshold (V-AT), distance traveled in the anaerobic zone (d(AT)), and VO(2)max. Methods. Sixty senior female football players were divided into LHIIT (n=30) and COD (n=30). Both groups underwent initial testing before participating in their respective training programs for four weeks. Performance metrics were measured at the beginning and end of the training period. Results. Both groups significantly improved all measured variables (p<0.001). However, the COD group demonstrated relatively more significant enhancements in Vmax (COD=0.93; LHIIT=0.8), VAT (COD=0.94; LHIIT=0.87), and VO(2)max (COD=0.92; LHIIT=0.74). The COD group also reduced the initial difference in VO(2)max to a non-significant level. Conclusion. COD HIIT protocols appear to be slightly more effective in enhancing anaerobic power in female football players than linear HIIT protocols. Nevertheless, both HIIT programs significantly improved performance metrics, indicating that incorporating such training regimens can benefit female football training programs.

Extensive research supports a pivotal role for the gut-brain axis(i.e., the communication pathway between the bacteria in the gut and the brain) in brain health and disease. The interplay between the gut microbiota and the mammalian nervous system appears to shape both adaptive and dysfunctional neurological processes, as it directly affects neurons and neural signaling, the immune response, and metabolism via its effects on hormones, neuropeptides, and neurotransmitters. This review summarizes key findings from the recent literature focused on the interactions between neurons and gut bacteria. By focusing on synthetic biology tools currently employed to study the gut-brain axis, we can enhance our understanding of neuroactive substances released in the gut and potentially identify select molecular candidates that may facilitate the development of personalized therapies.

Background. Coaches predominantly utilize linear training protocols to enhance the aerobic power of football players. However, there is limited data on the effects of change of direction (COD) protocols on aerobic power in football. Objectives. This study aimed to determine which high-intensity interval training (HIIT) program- linear (LHIIT) or change of direction (COD)-has a more significant impact on increasing aerobic power in senior female football players. Methods. Sixty senior female football players were divided into two experimental groups: LHIIT (n=30) and COD (n=30). Both groups underwent a four-week HIIT protocol, with LHIIT involving linear and COD incorporating change-of-direction exercises. Aerobic power was measured using the 30-15 intermittent fitness test (IFT), maximal aerobic velocity (MAV), and VO2max at the beginning and end of the study to assess the differences in aerobic adaptations between the two programs. Results. The results indicated that the COD group eliminated the significant difference in VO2max that initially existed between the two groups, suggesting that COD protocols may be more effective in increasing aerobic power than linear ones. Additionally, both groups significantly improved the 30-15 IFT, MAV, and VO2max. Conclusion. Both linear and change-of-direction HIIT protocols significantly enhance aerobic performance in senior female football players. However, COD protocols may have a more significant impact on VO2max improvement. Future research should explore the potential effects of COD protocols on anaerobic power and seek to identify even more effective HIIT strategies for enhancing VO2max.

In this paper, a special identity for twice differentiable functions, which is available in the literature, is utilized. By combining this identity with Riemann-Liouville fractional integrals, various fractional Milne-type inequalities are obtained for functions whose second derivatives in absolute value are s−convex in the second sense. Moreover, Hölder and Young inequalities are used to prove the different and original results. These approaches contribute to the analysis of s−convex functions and offer new perspectives in the field of fractional analysis.

Şahin, Sırrı; Ayata, Ümit; Esteves, Bruno
Color and glossiness are two important aesthetic properties of wood flooring and wood furniture that significantly affect consumers choice. With time the coating deteriorates altering the surface properties. Un-derstanding these changes is important for furniture industry, impacting design choices, material selection, and long-term maintenance. The effects of thermal aging (30 °C for 30 days, 60 °C for 60 days, and 90 °C for 90 days) on color parameters (C*, L*, b*. a*, ho) and glossiness on both perpendicular () and parallel (║) directions at 20°, 60°, and 85° angles in UV-cured coatings applied on sessile oak were studied. Results show that statistically significant differences were observed in the glossiness values, as well as in C*, b*, a*, L* and ho. As the temperature and duration of the thermal aging process increased, there was a noticeable increase in the values of color parameters b*, a*, and C*, while the values of ho and L* decreased. The characteristics of the surfaces exposed to thermal aging have undergone a complete transformation.

The present study sought to examine the relations between reading habits, perceived meaningful living, and optimism through structural equation modeling. To this end, we recruited undergraduate students enrolled in the Turkish language teaching program of a state university and collected the data using the Reading Attitude and Habits Scale, the Meaningful Living Scale and the Optimism-Pessimism Questionnaire. More than half (58.4%) of students were females, 52% were aged 21–30 years, and 34.2% were second-year students. The data were analyzed using SPSS 24.0 and SPSS AMOS 20.0. The findings showed a significant relationship between reading habits and meaningful living, with optimism serving as a significant mediator. Model fit indices confirmed the validity of the SEM model (RMSEA = 0.061, CFI = 0.94, TLI = 0.96). We also found that optimism served as a significant mediator in the relation between reading habits and perceived meaningful living. The findings suggest encouraging undergraduate students’ reading habits and designing and offering counseling services to foster students’ optimism and perceived meaningful living. Moreover, further research with diverse demographic groups is needed to elucidate more on the subject.

In this study, surface changes (whiteness index: WI*, color parameters, and glossiness properties) occurring after bleaching with oxalic acid (C2H2O4) and hydrogen peroxide (H2O2) + sodium hydroxide (NaOH) chemicals in kingwood (Dalbergia cearensis Ducke) wood, used for high-quality applications such as quality turning, marquetry, furniture, inlay work, musical instruments, and decorative items, were investigated. The ΔE* values were determined as 5.46 for the single component and 8.69 for the double component. Decreases in L* and ho parameters were obtained by the action of the C2H2O4 chemical, while increases were observed in the a*, C*, and b* parameters. Additionally, the use of H2O2 + NaOH chemicals in the bleaching process resulted in increases in L*, b*, C*, and ho values, with a decrease noted in the a* parameter. Observations revealed reductions in glossiness values at 60 and 85 degrees when employing two distinct bleaching agents in both orientations. It can be said that the bleaching agents used in the study exert varying effects as modifiers on the surface of wooden materials.

Background: Genetic and epigenetic mechanisms have been shown to play a role in the pathogenesis of atopic dermatitis (AD). However, the role of genes involved in the establishment of DNA methylation has not yet been demonstrated. Methods: A total of 15 pediatric patients with AD and 15 healthy volunteers were included in this study. The mRNA gene expression levels of eight different genes involved in the regulation of DNA methylation were examined in the blood and tissue samples. Results: The mRNA expression levels of DNMT3A genes were significantly increased, while the mRNA expression levels of DNMT3B, TET1, and TET2 genes were statistically significantly reduced in the lesional tissue of patients compared to the control group. It was observed that the mRNA expression levels of DNMT1, DNMT3A, and TET3 genes were increased, while the mRNA expression levels of DNMT3L and TET1 genes were found to be decreased in the blood of the patients. Conclusion: The results indicated that the DNA methylation pattern in the patients was hypermethylated, especially in the lesional tissue. The data obtained may contribute to the understanding of the epigenetic regulation of AD and aid in the development of new diagnostic and treatment options.

Gunes, Huseyin; Bulbuloglu, Semra; Saritas, Serdar; Ozdemir, Ahmet
Background: Postoperative kinesiophobia and gastrointestinal (GI) disorders are common and undesirable conditions following orthopedic surgery. Additionally, managing both conditions is crucial for preventing complications and accelerating recovery. The purpose of this study is to investigate the effects of kinesiophobia on GI disorders after lower extremity orthopedic surgery. Method: This study was conducted with a descriptive and cross-sectional design. The sample consisted of a total of n = 299 patients who underwent orthopedic surgery in their lower extremities at the orthopedics and traumatology clinic of a research and training hospital located in Turkey. A personal information form, the Tampa Scale of Kinesiophobia (TSK), and the Gastrointestinal Symptom Rating Scale (GSRS) were used to collect data, and the obtained data were analyzed using descriptive statistics, one-way analysis of variance (ANOVA), paired-samples t-test, and post hoc tests when necessary. Results: While 24.4% of the patients were aged 65–74 years, 51.5% were male. The mean total TSK score of the patients was above average (49.36 ± 8.74), while their mean total GSRS score was below average (31.22 ± 11.7). In our study, as kinesiophobia increased, the frequency of bowel movements decreased, and kinesiophobia explained 19.9% of the variance in GI disorders (p < 0.05). Conclusions: Kinesiophobia is a significant predictor of GI disorders in patients who underwent lower extremity surgery. Returning to normal GI function after surgery is crucial for preventing complications in patients with lower extremity surgery. Uncontrolled kinesiophobia after surgery exacerbates GI disorders. Therefore, early diagnosis and management of both kinesiophobia and GI disorders are necessary for rapid recovery in patients with lower extremity surgery. 2025 Gunes, Bulbuloglu, Saritas and Ozdemir.

Peker, Hüseyin; Ayata, Ümit; Ulay, Göksel
Scots pine is one of the important tree species used by the wood processing industry in many countries for both interior and exterior applications. It is well known that thermal treatment alters the color of wood. To protect wood from outdoor environmental conditions, certain chemicals are applied to its surface. These protective chemicals also influence the color of thermally treated wood. In this study, the color-altering effect of picture varnish (refined linseed oil), commonly used as a protective chemical in the field of painting, was investigated on both thermally treated and untreated wood materials. Scots pine (Pinus sylvestris L.) wood samples were subjected to thermal treatment at 212 °C for 2 h. Following this, varnish made from refined linseed oil was applied to some of these samples and some untreated samples, with the remaining untreated samples used as controls. Color and whiteness index (WI*) values were analyzed on the resulting four different materials, and the results were compared. Analysis of variance showed significant effects for the factors of heat treatment, picture varnish application, and their interaction, on WI* (|| and ⊥), a*, L*, ho, b*, and C* values. In the non-heat-treated samples, the application of varnish resulted in reductions in WI* values in both directions and in L* values, while increases were observed in ho, b*, C*, and a* values. Additionally, the application of varnish to the heat-treated samples resulted in an increase in a* values, while reductions were observed in WI* values in both directions, as well as in ho, L*, b*, and C* values. After heat treatment, the ∆E* value for Scots pine wood was calculated as 33.63. For both heat-treated and non-heat-treated samples, varnish application resulted in negative ∆L* values and positive ∆a* values. Additionally, ∆b* and ∆C* values were positive in the non-heat-treated and varnished samples, while they were negative in the heat-treated and varnished samples. The protective picture varnish used in the study significantly altered the color of both thermally treated and untreated wood.
