Polat, Eray; Çelik, Fatih; Ibrahim, Blend; Gursoy, Dogan
This paper reviews influencer marketing (IM)-research in the tourism and hospitality (H&T) field to provide a state-of-the-art of the past, present, and future of IM-research. It identifies research themes, theoretical underpinnings, and methodologies utilized in IM-research. Seventy-five studies are examined through co-citation, bibliographic coupling and content analysis based on the TCCM (theory/context/characteristics/methodology) framework. Co-citation analysis reveals that IM-research focused on travel blogs, vlogs, celebrity endorsement, influencer authenticity. An assessment of recent studies through bibliographic coupling indicates a partial shift toward the study of more contemporary issues. This field-discipline-focused hybrid-review contributes to literature and practice by presenting the past, present, and future of IM-research.

İncele - MakaleAçık Erişim2024Scopus SJRQ4An evaluation of the earthquake potential with seismic and tectonic variables for the West Anatolian region of Türkiye
Öztürk, Serkan; Alkan, Hamdi
In the present study, an evaluation of the region-time-magnitude behaviours of the earthquake occurrences in the West Anatolian Region (WAR), Türkiye, is carried out using the statistical and seis-motectonic parameters such as the b-value of Gutenberg-Richter relation, occurrence probabilities, and return periods of earthquakes. We also have mapped the Coulomb stress changes to observe the current and future earthquake hazard. In recent years, several large earthquakes such as the 1919 Soma (Mw = 6.7) and the 2022 and 2024 Aegean Sea (Mw = 5.3 and Mw = 5.1) revealed earthquake potential in the WAR. Coulomb stress analyses of 41 local events with mostly normal fault mechanisms have shown that posi-tive lobes (> 0.0 in bars) are mainly confined in the crust and uppermost mantle depths around Samos, Kos, and south of Lesvos. The smaller b-values (< 1.0) are observed in the same regions. On the contrary, we have observed a higher b-value from the offshore to onshore, south to north-trending direction, and negative scattered stress lobes (< 0.0 in bars) in slightly NW–SE oriented. The relationship between an increased b-value and negative stress change may indicate a similar seismicity for the region. In addition, we have analyzed the occurrence probabilities and return periods of the earthquakes, which showed us that Mw = 6.0 may occur at 75% in the intermediate term with an estimation of ~7 years. Our results reflect that these types of multiple-parameter assessments are important to define regional seismicity, seismic, tectonic, and statistical behaviours. Consequently, the areas with reductions in b-values and increments in stress imply the possible seismic hazard in the intermediate/long term.

Dogan, Nilgun; Adanacioglu, Hakan
Geographical indications (GIs) are defined as labels that show the relationship of a product with a certain region. They are of great importance in terms of distinguishing these products from the similar ones in terms of the quality that the characteristic features of the region bring to the product, making them stand out commercially, contributing to the rural development and preserving the cultural heritage. Dry beans cultivated by the farmers in the Gümüşhane province is newly recognized as a GI product that is unique in both taste and quality. This study is intended to identify the factors affecting the farmers’ decision to produce GI-labelled dry beans. The survey was conducted in January–March 2021. A sampling size of the participants consisted of 50 farmers who cultivated GI-labelled dry beans and 50 non-GI dry beans. A binary logistic regression analysis approach was employed to identify the factors affecting the likelihood of the farmers cultivating the GI dry beans. The results of the model indicate that the young farmers with the low educational level, the low property land size, the low yield per decare, and the large farmland, the high annual agricultural income and specializing in the dry beans production are more likely to engage in the production of GI dry beans. For the farms involving the GI product, agricultural associations can be advised with the farmers with the wider agricultural acreage and the high annual agricultural income, and that specialize in the production of such products. The participation of the farmers in the agriculture enterprises involving the GI dry beans will depend on them seeing positive widespread effects, which requires a long-term commitment.

Akbulut, Zeynep; Karsli, Fevzi; Dihkan, Mustafa
Ground filtering is an essential process that separates ground and non-ground points for generating digital elevation models (DEMs) from airborne laser scanning (ALS) point cloud data. Traditionally, ground filtering was carried out using rule-based approaches, but with the advancements in deep learning networks, ground filtering can now be performed using these methods. Deep neural networks (DNNs) require large amounts of training samples to reveal key information within the dataset. OpenGF is a new ultra-large-scale dataset which has nearly half a billion points from nine different scenes ranging from highly dense urban areas to steep vegetation covered mountains for ground filtering task. In this study, PointNet++ architecture was employed for ground filtering on the OpenGF dataset. Firstly, we slightly modified PointNet++ architecture’s sampling strategy to decrease the number of duplicate points in the batching process. We proposed a new adaptive tiling strategy based on input point cloud density to cope with highly varying point sampling of the OpenGF dataset. Modified PointNet++ architecture was trained with both adaptive tiling strategy and original OpenGF tiles to investigate the advantages and drawbacks of the proposed strategy on the ground filtering task. To evaluate the performance of the proposed strategy, the results for different test areas were compared with those obtained using the original PointNet++ and rule-based cloth simulation filtering (CSF) algorithms. Despite using fewer epochs, the proposed data collection strategy achieved up to 13% higher accuracy on test scenes with the modified PointNet++ architecture compared to the network trained with original OpenGF tiles.

Yildiz, Eyyüp; Bostan, Sedat
A concept that inspired social sciences as well as many other fields of science was developed from chaos theory. Disaster researchers are also trying to approach, understand, explain and manage disasters with this new concept. However, it has been observed that studies investigating disasters from this perspective do not focus on disaster sources. With this starting point, in this research, the chaotic factors that prepare the disaster formation were investigated with the example of earthquake. The study was carried out with the qualitative method. Data were collected by semi-structured online interview. Participants were selected by purposive sampling method. The interview data obtained from a total of 10 participants were managed with the MAQXDA 2018 software package using the traditional content analysis method. All codes were classified into three themes and 11 categories. According to the findings, earthquakes can be dealt with in three different chaotic periods: a natural event, a natural event that turns into a disaster, and disaster response and recovery. Future research is recommended to explain the dynamics of occurrence of other disasters such as floods, storms, explosions, and epidemics. It is recommended that disaster management practitioners integrate the chaos management approach into disaster management. With this, it is hoped that disaster management will shift from a linear, bureaucratic, command-control approach to a community-based, flexible, continuous planning approach in which even the smallest occurrences are carefully monitored.

Günen, Mehmet Akif
Detecting building rooftops with very high-resolution (VHR) images is an important issue in many fields, including disaster management, urban planning, and climate change research. Buildings with varying geometrical features are challenging to detect accurately from VHR image due to complicated image scenes containing spectrally similar objects, illumination, occlusions, viewing angles, and shadows. This study aims to detect building rooftops with high accuracy using a new framework that includes VHR image, visible band difference vegetation index, digital surface and elevation models, the terrain ruggedness and the topographic position index. Five distinct feature sets were generated in order of importance by exposing the ten related stacking features to a feature selection procedure using the maximum relevance minimum redundancy method. Then, Auto-Encoder, k-NN, decision tree, RUSBoost, and random forest machine learning algorithms were utilized for binary classification. Random forest yielded the highest accuracy (97.2% F-score, 98.72% accuracy) when all features (F10) were used, while decision tree was the least successful (59.16% F-score, 83.56% accuracy) for RGB feature set (FRGB). It was revealed that classification of F10 with random forest increased F-score by about 23% compared to classification with FRGB. Additionally, McNemar’s tests showed no statistically significant difference between random forest vs k-NN and decision tree vs RUSBoost.

Boynueğri̇ Kaplan, Emine; Şüküroğlu, Ebru Emine
In this study, an alumina (Al2O3) ceramic coating and a composite coating containing titanium dioxide (TiO2) particles were prepared on surfaces of AA2024 substrates by micro-arc oxidation (MAO) treatment. The effects of micro-sized (≈20-30 µm) TiO2 particles incorporated into electrolyte on the microstructure, phase and chemical composition, thickness, and friction behavior of the coating were investigated. The surface morphologies of the coatings were analyzed by scanning electron microscopy (SEM). The phase and chemical compositions of the coatings were evaluated by means of X-ray diffraction (XRD) and energy-dispersive X-ray spectrometry (EDS), respectively. The friction coefficient of the coatings was investigated using a pin-on-disc tribometer under condition of dry slip sliding. Moreover, the wear tracks were analyzed by SEM. Addition of TiO2 particles into the electrolyte resulted in the reduction in number of pores and formation of smaller and more uniform pores in comparison with the Al2O3 ceramic coating. XRD analyses demonstrated that the TiO2:Al2O3 composite coating was composed of anatase-TiO2 and rutile-TiO2, as well as pure aluminum, α-Al2O3 and γ-Al2O3 which are the primary phases. The friction tests showed a significant reduction in the friction coefficient of the composite coated samples which contains titanium oxide (TiO2) particles in comparison with Al2O3 coated and uncoated samples.

Oba, Sirin; Yildirim, Tugce; Karataş, Şeyda Merve
In recent years, interest in probiotics has increased as functional foods improve quality of life and consumers become more health-conscious. The European Food Safety Authority (EFSA) has determined that all common probiotics are safe for the general population. However, this definition does not guide the outcomes of using probiotics in people with diseases that favor them, as there are no strict regulations governing applicable trademark law and the manufacture of probiotics. For this reason, Probiotics are recognized to be beneficial for the majority of patients during treatment; however, patients with weakened immune systems may be at risk for bacteremia, endocarditis, and peritonitis. There are no necessary standards regarding safety and use protocols for probiotics. More information is needed on their use before recommending probiotics to treat or prevent disease in privileged groups. These products may be considered a public health concern by reviewing information on the use of probiotics to predict the likelihood of side effects in vulnerable groups (young children, the elderly, and pregnant women).

The aim of this study is to examine the mediating role of emotion regulation difficulties in the relationship between conflict resolution styles and marital satisfaction in married individuals. A total of 706 married individuals, 234 men and 472 women, constitute the study’s working group. The ages of the participants ranged from 21 to 60, with an average age of 38.45. As a result of the analysis conducted within the scope of the study It has been found that positive conflict resolution, retreat and subordination conflict resolution styles are positively related with marriage satisfaction, while negative conflict resolution styles are negatively related with marriage satisfaction. The results show that positive conflict resolution, negative conflict resolution, retreat and subordination conflict resolution styles have a direct effect on marital satisfaction, but this effect does not disappear when emotion regulation difficulties is controlled, so emotion regulation difficulties play a partial mediator role.

Yanarates, Cagfer; Altan, Aytac
In this study, enhanced hysteresis droop control for equivalent and fast load sharing in parallel PWM DC-DC converters is presented. The basis behind the work encompasses power system stability, reliability, efficiency, reduction of losses and decrease in the operational cost. In this context, phase management, which constitutes the biggest problem, and the resulting factors such as ripple cancellation, thermal stress, transient response behavior and complexity, is aimed to manage with the proposed control scheme. Performance evaluation of the proposed system is based on sensitivity analysis against possible disturbance and noise, and comparative analysis with PI controller against uncertainty and parameter variations using mathematical modeling and simulation techniques. The results show that the proposed controller has improved performance in both noise attenuation and disturbance rejection at typical switching frequencies of DC-DC converters ranging from 100 kHz to a few MHz. Additionally, applying the proposed control technique considering 10% parameter variations led to the largest difference being recorded at 4% while this difference was 18.68% in conventional PI control. According to the findings of the simulation, the proposed control scheme reduces the settling time by a factor of 4.89, whereas it takes 775.862 μs seconds with the PI controller. Furthermore, with the suggested controller, the overshoot - which was 36.09% with the PI controller - is reduced to just 1%.

Sarı, Tuğba; Gürhan, Nermin; Uzun, Sevda
BACKGROUND: Some pregnant women have negative emotions that may predominate and they may develop a fear of childbirth. This causes negative consequences for their health and well-being. A complete definition of the causes of childbirth fear has not yet been established in the literature, but in a systematic review, various factors were found. OBJECTIVE: This study aimed to reveal the effect of educational, cognitive, and behavioral interventions on the reduction of fear of childbirth (FOC) in pregnant women. METHODS: For this meta-analysis study, articles in PubMed, EBSCOhost, Web of Science, YÖK Thesis Center, and Google Scholar databases were searched without any year limitation in between September 2022 and February 2023. A total of 25 studies were included in this meta-analysis. The data were analyzed by meta-analysis and narrative methods. RESULTS: This meta-analysis showed that educational, cognitive, and behavioral interventions were effective in reducing FOC in pregnant women (standardized mean difference: −1.229, 95% confidence interval [−1.586, −0.872]; Z = −6,746, p = .000, I2 = 94.225%). In subgroup analyzes, intervention types such as antenatal education, mindfulness, psychoeducation, and psychotherapy were found to be effective in reducing FOC. Interventions applied to women who have FOC reduce the FOC and provide a more positive birth experience. CONCLUSION: Results of the present study showed that educational programs could serve as an important tool in reducing women’s fear from natural childbirth and in choosing physiologic birth.

This study aimed to synthesize and characterize silver nanoparticles (AgNPs) by green synthesis from Equisetum arvense (Ea) extracts and to investigate their cytotoxicity, antibiofilm activity, and α-glucosidase enzyme inhibition. Diverse characterization techniques were applied to verify the production of nanoparticles. SEM examination confirmed that the size of nanoparticles is in the range of 40–60 nm. Also, interactions between silver and natural compounds of plant extract were confirmed through FT-IR and EDX analyses. It was determined that Equisetum arvense silver nanoparticles had antibiofilm activity against three different clinical strains with high biofilm-forming ability. AgNPs reduced the biofilm-forming capacity of clinical A. baumannii isolate with strong biofilm-forming capacity by approximately twofold, while the capacity of clinical K.pneumonaie and E.coli isolates decreased by 1.5 and 1.2 fold, respectively. The α-glucosidase enzyme inhibition potential of the AgNPs, which is determined as 93.50%, was higher than the plant extract with, and the α- 30.37%. MTT was performed to assess whether incubation of nanoparticles with A549 and ARPE-19 cell lines affected their viability, and a dramatic reduction in cell growth inhibition of both A549 and ARPE-19 cells was observed. It has been shown that A549 cells treated with 200 and 150 µg/mL nanoparticles had less cell proliferation compared to control cells at 24-h and 48-h incubation time. According to these results, Ea-derived AgNPs appear to have potential anticancer activity against A549 cancer cells. Investigating the effects of green synthesis nanoparticles on microbial biofilm and various tumors may be important for developing new therapies. The outcomes of this study have showed that Ea-AgNPsmay have a high potential both in the treatment of pathogenic strains that form biofilms, as well as in anticancer therapy use.

Dogu, Fatma Tuana; Dogan, Hulya; Dogan, Ramazan Ozgur; Ay, Ilyas; Sezen, Sena F.; Seyman, M.
During microscopic examination process, experts firstly determine the most appropriate focusing point by precisely moving the microscope stage in the Z axis. This manual focusing process may cause variability in results depending on hand-eye coordination and individual experience. Therefore, the development of automatic focusing offers superior quality and consistent imaging. Many researchers have studied automatic focusing systems and proposed many focus functions to extract focus information from multi-focus images. Nevertheless, these focusing systems still consist of several significant limitations such as requiring a supplementary material, longer running time, producing different performance depending on the sample and magnification objective. In this study, an efficient technique based on deep learning is proposed to automatically determine the focused image during microscopic examination processes to minimize these limitations in the literature. This technique takes a sequence of images with the same field of view and different focuses as input and gives the image with maximum focusing as output. The proposed technique is compared with other automatic focusing techniques on the literature. In this study, novel multi-focus image sequences obtained from liver, intestine, heart, kidney, and lung samples is prepared to evaluate the performance of automatic focusing techniques. These sequences are obtained by scanning with 10× and 40× magnification objectives. Running time, accuracy, number of local maximum points, range, and noise levels are used as evaluation criteria in this study. According to evaluation criteria results obtained in this study, it has been proven that the proposed technique provides better performance than other automatic focusing techniques.

İlgar, Gamze; Terhan, Meryem
In the study, the effect of phase change materials integrated into the building's external wall has been investigated in terms of material type, thickness, and melting temperature of phase change material on the building energy performance for İzmir Province. A villa residential project has been modelled in 3D using DesignBuilder energy simulation software and two different external wall configurations have been designed by changing the position, thickness and melting temperature of the PCMs into the wall. The amount of CO2 emission reductions that PCMs will provide according to the fuel type of the building's heating system has been calculated. Using PCMs in the external wall not only provides high heating and cooling energy savings but also increases thermal comfort indoors by reducing temperature fluctuations. The PCM melting temperature of 23℃ performs quite well compared to other temperatures in both cooling energy and heating energy demand reduction. By increasing the triple thickness of the PCM, 18.81% in heating energy and 22.85% in cooling energy savings can be achieved. Depending on the external wall and phase change material types, different thicknesses and melting temperatures of PCM, annual total energy saving of the phase-change material is calculated between 10,349.50-83,345.98 kJ/m2.year and the annual CO2 emission reduction according to fuel types has been found as 0.672-14.284 kgCO2/m2.year.

Ürkek, B.; Tunçtürk, Y.
In this study, Kashar cheese milk was homogenized at three different levels (0, 10 and 15 MPa). The produced Kashar cheeses were ripened for 90 d at 4 °C as covered with paraffin or uncovered. Some chemical properties, proteolysis, lipolysis, peroxide and thiobarbituric acid (TBA), and microbiological characteristics of Kashar cheeses were examined during storage. The values of all chemical, biochemical and microbiological parameters increased at the end of ripening compared with the beginning of ripening in all samples. Proteolysis values in cheese samples generally decreased with homogenization pressure. Lipolysis, peroxide, TBA values of samples were decreased depending on the homogenization pressure. The proteolysis, lipolysis, TBA, and peroxide values of samples covered with paraffin were slightly lower than those uncovered. The yeast-mould counts were lower in covered samples compared with samples uncovered. Consequently, the homogenization process (especially 10 MPa) and covering with paraffin in packaging can be used in the production of Kashar cheese.

Köseoğlu, Ali; Şahin, Rıdvan; Kahraman, C.; Cevik Onar, S.; Cebi, S.; Oztaysi, B.; Ucal Sari, I.; Tolga, A.C.
Fuzzy sets allow elements to have partial membership in a set, represented by a membership value between 0 and 1. This feature enables fuzzy sets to model imprecise or vague concepts. Decomposed fuzzy sets, an extension of fuzzy sets, have introduced a novel perspective in the literature by incorporating the Kano model into risk assessment. These sets have also paved the way for new approaches in decision-making methods, highlighting their functional and dysfunctional elements. In this paper, we propose a distance measure for decomposed fuzzy sets and subsequently extend the TODIM method based on this distance measure to DFSs. Then, we provide a numerical example to illustrate its effectiveness and practicality.

Özbek, Mehmet Ferhat; Yoldash, Mohammad Asif; Tang, Thomas Li-Ping
Research suggests that organizational justice has important impacts on work-related attitudes and behaviors, such as organizational citizenship behavior (OCB). In this article, we explore the extent to which individualism moderates the relationship between organizational justice (procedural, distributive, and interactional justice) and OCB (organizational obedience, participation, and loyalty) among citizens in Kyrgyzstan. Specifically, we are interested to know: Which aspects of justice perceptions excite organizational loyalty? We make additional contributions to the literature because most global researchers know very little about how these Western management constructs prevail in this former Soviet Union country, Kyrgyzstan, an under-researched and under-represented region of the world. Results of our data collected from 402 managers and employees in Kyrgyzstan offer the following discoveries. All three justice constructs are related to OCB. Individualism moderates the relationships between (1) distributive justice and organizational participation, (2) distributive justice and organizational loyalty, and (3) interactional justice and organizational loyalty. We develop an intricate theory with provocative implications: Procedural justice produces obedience only and has no impact on organizational participation and loyalty. High distributive justice enhances high loyalty for people with low individualism. High interactional justice promotes high organizational loyalty for people with high individualism. For “individualists,” interactional justice inspires loyalty. Interestingly, distributive justice “can only buy” participation, but “can’t buy” loyalty. Therefore, for individualists, interactional justice outweighs distributive justice for enhancing organizational loyalty. Based on Kyrgyz citizens’ justice, OCB, and individualism, our theory reveals novel insights regarding culture, money attitude, and intrinsic motivation and provides critical and practical implications to the field of business ethics.

Çetin, Gökhan; Ünker, Faruk
The control moment gyroscope’s (CMG) success in emerging damping control under impact load is of great interest for new technical applications. This paper explores the potential use of a two-wheeled robot with an independent weapon, such as an automatic cannon robot, and considers employing CMG with LQR control as a weapon recoil stabiliser for the robot. Cannon turret firing accuracy is crucial for optimising LQR control parameters and enhancing weapon-robot performance. CMG with LQR control effectively reduces the recoil impact loads of the overhead weapon while compensating angular momentum to ensure safety for robot in firing. The precession motion of the gimbal from several milliradians to tens of milliradians is one of some contradictions for describing the effect of the recoil force on robot–gyroscope performance. This paper uses computational methods, combined with CAE software, to study the impact of increasing angular momentum on recoil-induced weapon vibrations.
