Yaprak, Busranur; Gedikli, Eyup; Badica, C.; Ivanovic, M.; Koprinkova-Hristova, P.; Leon, F.; Manolopoulos, Y.; Yildirim, T.; Ucar, A.
Gait recognition aims to identify people from a distance by analyzing their walking style. Nevertheless, the efficacy of recognition drops significantly under cross-view and, appearance-based variations such as carrying and clothing. In this study, the performance of the MobileNet-V1 deep network is evaluated in various scenarios to address the cross-view gait recognition problem. In the first scenario, the fine-tuned MobileNet-V1 is evaluated on Gait Energy Images (GEI) as input data, while in the second scenario, the fine-tuned MobileNet-V1 is assessed with Optical Flows and masked RGB frames input data. In the last scenario, the first two scenarios are combined over a single fused deep network based on finetuned MobileNet-V1, and a single recognition process is performed using two different fused features data; GEI features with Optical Flow features, and GEI features with masked RGB frame features. In the evaluation process, a comprehensive data set for the cross-view gait recognition problem, CASIA-B is used for the experiments. The obtained results demonstrate that in the last scenario, the contribution of masked RGB frame features to the recognition rate of GEI is more significant.

Kayln, Sercan; Işseven, Turgay
One of the major challenges facing geochemistry, petrology, and volcanology researchers is the difficulty in determining the origin and paleo-flow directions of igneous and volcanic rocks. It is not possible to clearly determine origins and paleo-flow directions in areas with numerous volcanic centers. Anisotropy of magnetic susceptibility (AMS) is a valuable method that provides insights into the origins and paleo-flow directions of lavas that are complex to study. The presence of volcanic materials with thicknesses up to 1 km, coming from different sources at varied time intervals in the north of Lake Van, makes this area an ideal setting for implementing AMS in establishing paleo-flow directions. This study presents the magnetic mineralogy and AMS analysis of volcanic rocks from the Miocene to the Quaternary in the Lake Van region. We conducted isothermal remanent magnetization (IRM) and high-temperature susceptibility (HTS) studies to determine the magnetic mineralogy. IRM studies revealed that (titano)magnetite is responsible for the magnetization in most samples, while both (titano)magnetite and hematite are responsible for the rest. Alteration degrees and Curie temperatures of the rock samples were also determined through HTS measurements. There is good agreement between the anticipated directions of lava flow and our findings for nearly all volcanic rocks.

Muslu, Ayşe; Üçüncü, Osman; Baltacı, Cemalettin
The compound 5-(hydroxymethyl)furfural (HMF) has emerged as a versatile intermediate with the ability to undergo conversion into both fuel and a variety of platform chemicals. Lignocellulosic biomass, such as hazelnut shells and tea processing residues, was employed in this study for HMF production through two distinct methods. In the first method, cellulose from biomass was converted to sugars using a 4% acid solution, followed by catalytic conversion with NaCl/CrCl3.6H2O. After a 1-h reaction at 131 °C in a high-pressure system, HMF was obtained from tea processing waste and hazelnut shells with yields of 8.6% (82.3 mg/g) and 6.7% (66.7 mg/g), respectively. The second method involved LiCl/NaCl-doped N,N-dimethylacetamide (DMA) as an ionic solvent system for HMF production. After a 2-h reaction at 131 °C in the DMA-NaCl/[EMIM]Cl ionic solvent system, HMF was obtained from tea processing waste and hazelnut shell celluloses with yields of 5.7% (57.5 mg/g) and 3.1% (31.3 mg/g), respectively. This study contributes to the economic conversion of various food wastes into valuable chemicals, highlighting the potential of lignocellulosic biomass in sustainable chemical production.

Ulutaşdemir, Nilgün; Ay, Halil; Göçmen, Adalet; Uzun, Sevda; Kulakaç, Nurşen
OBJECTIVE: To determine the practices and coping experiences of the relatives of patients with pressure injuries (PIs). METHODS: The authors used a qualitative, phenomenologic research design. They interviewed 20 relatives of patients with PIs face-to-face using an in-depth semistructured interview form. The data were analyzed using the Colaizzi phenomenologic method. RESULTS: Three categories, 8 main themes, and 22 subthemes emerged from the interviews. The category of “the impact of the need for care on the lives of the patient’s relatives” was analyzed according to psychological, social, and physical effects. In the category of “practices to prevent pressure injuries,” two themes emerged: practices toward the patient and the environment. Relatives of individuals with PIs have psychological, physical, and social needs. CONCLUSIONS: Providing care to a patient with PIs has psychological, social, and physical effects on the patient’s relatives. The care burden mostly affects these caregivers negatively, and they mainly need time for themselves and moral and companion support.

This paper presents a sentiment analysis combining the lexicon-based and machine learning (ML)-based approaches in Turkish to investigate the public mood for the prediction of stock market behavior in BIST30, Borsa Istanbul. Our main motivation behind this study is to apply sentiment analysis to financial-related tweets in Turkish. We import 17189 tweets posted as "#Borsaistanbul, #Bist, #Bist30, #Bist100″ on Twitter between November 7, 2022, and November 15, 2022, via a MAXQDA 2020, a qualitative data analysis program. For the lexicon-based side, we use a multilingual sentiment offered by the Orange program to label the polarities of the 17189 samples as positive, negative, and neutral labels. Neutral labels are discarded for the machine learning experiments. For the machine learning side, we select 9076 data as positive and negative to implement the classification problem with six different supervised machine learning classifiers conducted in Python 3.6 with the sklearn library. In experiments, 80 % of the selected data is used for the training phase and the rest is used for the testing and validation phase. Results of the experiments show that the Support Vector Machine and Multilayer Perceptron classifier perform better than other classifiers with 0.89 and 0.88 accuracy and AUC values of 0.8729 and 0.8647 respectively. Other classifiers obtain approximately a 78,5 % accuracy rate. It is possible to increase sentiment analysis accuracy with parameter optimization on a larger, cleaner, and more balanced dataset by changing the pre-processing steps. This work can be expanded in the future to develop better sentiment analysis using deep learning approaches.

Yalcin, Kadir; Dogan, Ramazan Ozgur; Dogan, Hulya; Bingol, Ozkan
Biometric technologies have been widely adopted in various commercial products, ranging from security systems to personal devices, due to their exceptional reliability and user-friendliness. Among these, palmprint biometrics has gained increasing attention for its advantages, such as ease of use, a larger surface area, and the ability to capture more features compared to other biometric methods. A typical palmprint biometric system involves five key stages: (a) Image Acquisition, (b) Hand Segmentation, (c) Pattern Generation, (d) Feature Extraction, and (e) Verification/Identification. The overall success of the system depends on the effectiveness of each stage, with hand segmentation being crucial for identifying the most relevant features for accurate verification. This study aims to achieve high-accuracy biometric recognition by segmenting hands from images captured in uncontrolled environments with complex backgrounds. Accuracy (ACC), Intersection over Union (IoU), F1-Score, and Dice Coefficient are the four critical metrics used to assess the performance of segmentation techniques. The findings demonstrate that the U-Net + ViT and MA-Net + ResNet34 techniques outperform traditional auto-encoder methods in both quantitative performance metrics and visual analysis, leading to significantly improved hand segmentation for biometric systems.

Tuncer, Gülsüm Zekiye; Tuncer, Metin; Duman, Zekiye Çetinkaya
Negative attitudes and beliefs leading to discrimination against individuals with obesity and to their exclusion can cause these individuals to experience various biological, psychological, and social problems. Nursing students constitute the group that will provide care, services, and counseling to individuals with obesity in the future. The present study was aimed at determining the relationship between nursing students’ attitudes toward and beliefs about individuals with obesity and their empathy and body image flexibility levels. This study that has a cross-sectional correlational research design was conducted with 445 students studying at Dokuz Eylül University Faculty of Nursing between February 2023 and July 2023. The Sociodemographic Information Form, Beliefs About Obese Persons (BAOP) scale, Attitudes Toward Obese Persons (ATOP) scale, Body Image Flexibility Scale (BIFS), and Toronto Empathy Scale (TES) were used as data collection tools. In order to ensure explanatoriness in the analysis of the data, the multiple regression/ correlation analysis was performed to determine the relationship between the scores for the overall BAOP and ATOP scales, which were dependent variables, and BMI and the scores for the overall TES and BIFS, which were the independent variables. The mean scores that the students participating in this study obtained from the overall BAOP and ATOP were 23.89 ± 4.49 and 72.48 ± 11.19, respectively. The mean scores they obtained from the overall TES and BIFS were 51.61 ± 8.80 and 52.19 ± 15.28, respectively. The results demonstrated that higher levels of empathy and body image flexibility were significantly associated with lower levels of negative beliefs about individuals with obesity (B = −0.107, p =.026; B = 0.271, p <.001) and positive attitudes toward individuals with obesity (B = −0.143, p =.002; B = 0.343, p <.001). In the study, as the students’ empathy and body image flexibility levels increased so did their positive perceptions toward individuals with obesity. Nurses should acquire empathic skills during their education in order to demonstrate an equitable and inclusive approach to care and to provide positive health experiences to individuals with obesity. In order for young people studying at university to be more responsive to others, they should be encouraged to develop body image flexibility for their own and others’ bodies. It is also recommended that topics on combating stigma and discrimination to prevent negative attitudes toward and beliefs about individuals with obesity should be added to the curriculum of nursing students.

The aroma of fermented dairy products is greatly influenced by starter cultures and by the lactic acid bacteria strains that are used as starter cultures. Experimental butter samples were produced using no starter culture, by a commercial starter culture (Lactococcus lactis subsp. lactis, Lactococcus lactis subsp. cremoris, Lactococcus lactis subsp. lactis biovar. diacetylactis, Leuconostoc mesenteroides), by a prepared bacteria mix (Lactococcus lactis subsp. lactis EM1, Lactococcus lactis subsp. cremoris EM28, Lactococcus lactis subsp. lactis biovar. diacetylactis G49, Leuconostoc mesenteroides B3), and by a prepared bacteria mix fortified with Lactobacillus rhamnosus B19 (L. rhamnosus B19). The aroma profile of the butter samples was investigated using a gas chromatography mass spectometry method (GC-MS). A total of 92 components were determined in the butter samples, including acids (12), alcohols (20), aldehydes (9), alkanes (6), esters (8), ketones (19) and several other aroma compounds (18). The sample containing the prepared starter culture had the most detectable aroma components, while the lowest number of aromatic components were found in the sample without a starter culture. 2,3-butanedione (diacetyl) was not detected in the sample without a starter culture. 2-Butanone 3-hydroxy-(acetoin) content was the highest in the sample containing the commercial starter culture and the lowest in the sample without a starter culture.

Çelik, Kemal
Expropriation is widely used to introduce highway projects into the society. Expropriation is the registration process of real estate and equities owned by natural and legal persons on behalf of the administration for public interest, provided that property and easement right amount shall be paid in cash or in advance or by equal installments. In what situations and by which institutions expropriation is carried out are restricted by the law. In accordance with the Article 3 of the Expropriation Law Number 2942 amended by the Law Number 4650, the expropriation process shall not be started without an adequate allowance provided by the administration. The exercise of the right of property shall not be against public interest.” Project areas are required to be converted into public property after the development plans for the public projects are prepared. Areas regarded as private property but intersected by highway, railway or waterway routes can only be occupied after expropriation. Without expropriation, projects based on transportation in improvement areas can be opened to public with the application of the provisions of the Development Law Number 3194, while those in areas having no development plan can be opened to public with the application of the relevant provisions of the Agricultural Reform Law Number 3083 on Land Consolidation in Irrigated Areas and Law Number 5403 on Soil Conservation and Land Use. In this article, opening highways, railways, and waterways to public in Türkiye using the implementation of development plans is discussed. For the real estate coinciding with the route of public investments, if land and land lots are arranged in accordance with the Article 18 of the Development Law Number 3194, state withholding up to 45% may be imposed. The objective function in the state withholding can be stated as f= costmin= f(a,b). Land acquisition increases as the ratio of state withholding increases, resulting in the minimization of the expropriation costs. Public projects such as highway can be opened to public free of charge with development plan implementation in improvement areas and with land consolidation in rural areas having no development plan.

This study explores, the impacts of incorporating of deep eutectic solvent (DES) as plasticizer on the characteristics of zein films. Investigation focused on examining the mechanical, thermal, surface, and microstructural properties of zein films that were plasticized using DES. The findings of the study revealed that by adding DES to zein films, there was an observed improvement in transparency. Additionally, it was observed that up to a 20% addition of DES led to a reduction in water vapor permeability (WVP). However, beyond this level, the WVP increased as the surface hydrophobicity decreased. The films that were plasticized with DES showed higher tensile and burst strength values than control. However, there was a decrease in the elongation at break and burst distance, except for the film containing 30% DES. The addition of DES as plasticizer resulted in smoother surface morphology compared to the control, and all films revealed homogeneous and non-porous surface and cross-section microstructure. The films plasticized with DES displayed three different thermal degradation temperatures resulting in higher thermal stability. The FT-IR spectrum of films showed similar backbone structure including Amide I, II and III bands. However, 5% DES plasticized film showed different secondary structural peaks of Amide I band due to lower α-helix and higher β-sheet and random coil content. The findings of this investigation indicate that the employment of DES as plasticizer in biodegradable polymer films can yield enhanced mechanical and barrier characteristics compared to conventional plasticizers, thus demonstrating its potential for effective use.

SUMMARY OBJECTIVE: This study aims to examine the relationship between body image and the level of sexual satisfaction in women who have undergone a hysterectomy. METHODS: This descriptive study utilized a relational screening model. Conducted between June 2023 and March 2024, the study included a total of 300 sexually active women who had undergone a hysterectomy 6 months prior. Data were collected using a personal information form, the Golombok-Rust Sexual Satisfaction Scale, and the Body Image Scale through face-to-face interviews lasting approximately 20–30 min. RESULTS: The average age of the participating women was 44.4±10.55 years. Of the participants, 96.7% were married and 42.4% had entered menopause. The average score on the Body Image Scale was 81.2±3.8, and the average score on the Golombok-Rust Sexual Satisfaction Scale was 33.0±15.1. A positive significant relationship was found between body image and sexual satisfaction (p<0.05). There was also a statistically significant positive relationship between the total scores on the Body Image Scale and the Golombok-Rust Sexual Satisfaction Scale with age and frequency of sexual intercourse (p=0.049, p<0.001, p<0.001, p=0.047, and p=0.014). It was determined that as the age and frequency of sexual intercourse increased, the levels of body image and sexual satisfaction also increased. CONCLUSION: Our study found that women’s self-image is negatively affected, and their level of sexual satisfaction decreases following a hysterectomy.

The purpose of this study is to investigate the impact of different durations of Swedish massage on the static and dynamic balance at different times of the day in taekwondo athletes. Twelve taekwondo athletes who had been practicing on a regular basis for more than 5 years participated in this study. Taekwondo athletes completed static and dynamic balance tests either after a no-massage protocol (NMP), a five-minute massage protocol (5MMP), a ten-minute massage protocol (10MMP), or a fifteen-minute massage protocol (15MMP) two times a day in the morning (08:00–12:00) and in the evening (16:00–20:00), on non-consecutive days. The findings of this study suggest that the duration of the massage has a discernible impact on dynamic balance, particularly with regard to the right foot. Taekwondo athletes who received a 10MMP or 15MMP displayed significantly improved dynamic balance compared to those in the NMP. Importantly, these improvements were independent of the time of day when the massages were administered. It underscores the potential benefits of incorporating short-duration Swedish massages into taekwondo athletes’ pre-competition routines to enhance dynamic balance. These findings highlight the potential benefits of incorporating short-duration Swedish massages into taekwondo athletes’ pre-competition routines to enhance dynamic balance, a critical component of their performance, regardless of the time of day.

The aim of this study is to determine the potential toxic element (PTE) content linked to the geochemical features of Berriasian–Aptian carbonate rocks commonly outcropping in Gümüşhane, along with the degree of pollution and possible sources of these toxic elements, and to compare dolomite with limestone in terms of toxic metal abundance. In the field, dolomite and limestone samples were collected by measuring stratigraphic sections around Yuvacık, Ünlüpınar, Çukutbaşı, Bağlarbaşı, Mescitli and Gülaçar (Gümüşhane). The samples were analyzed using inductively coupled plasma mass spectroscopy (ICP-MS). The mean values for Mo, Cu, Pb, Zn, Ni, As, and Co were 3.1, 23.8, 7.1, 14.5, 13.5, 30.9, and 8 mg/kg in Yuvacık; 6, 2.3, 1.1, 3.5, 8.1, 12.3 and 2.5 mg/kg in Ünlüpınar; 17.9, 1.8, 1.5, 8.6, 7.9, 13.9 and 1.7 mg/kg in Çukutbaşı; 3.7, 6.5, 31.7, 82.7, 9.5, 32.0 and 1.9 mg/kg in Bağlarbaşı; 0.7, 0.7, 7.1, 21.3, 2.6, 11.8 and 0.7 mg/kg in Mescitli; and 1.2, 1.1, 2.4, 5.2, 1.3, 4.0 and 0.2 mg/kg in Gülaçar, respectively. According to geochemical pollution parameters [geo-accumulation (Igeo), pollution index (Pi), and pollution load index (Pln)], the rocks were generally significantly polluted by Mo and As, without notable pollution by the other elements. Limestone samples from the Yuvacık, Ünlüpınar, and Çukutbaşı areas were more polluted in terms of Mo and As compared to dolomites. This pollution in Yuvacık and Ünlüpınar was identified to have geogenic sources (Pb–Zn–Cu mineralization) and in Çukutbaşı was identified to have lithogenic sources. Dolomites from the Bağlarbaşı area were more polluted in terms of As and less polluted in terms of Mo compared to limestones. In the Mescitli location, both dolomites and limestones were occasionally polluted in terms of As, while limestones were polluted in terms of Mo. In these two areas, the sources of As and Mo are geogenic (Pb–Zn mineralization), In Gülaçar, dolomites were more polluted in terms of Mo and less polluted in terms of As compared to limestones. In this locality, As and Mo are thought to have a geogenic source (Pb–Zn–Cu mineralization).

Objective: The Ombudsman is essentially an independent, national-level institution that operates in response to complaints from citizens in order to steer public administrations away from bad administrative practices and behavior. However, it is impossible for an ombudsman with such a broad mandate at the national level to deal with all administrative complaints within the state. Therefore, in order to get more efficiency from the national Ombudsman, it has been divided into different sub-types. Theoretical Framework: One of these is the Ombudsman for local governmentrs, which deals only with complaints from local administrations. Although there is a national ombudsman in Turkey, there is no ombudsman specialized in local governments. Method: This study aims to make some suggestions for the Ombudsman for local governments envisaged to be established in Turkey in the future by analyzing the local governments ombudsman offices in the UK and Italy in terms of their structural-institutional and functional aspects. In this context, the study, with a comparative approach, provides suggestions for the basic aspects, qualities and characteristics of the Turkish local government ombudsman and, thus, for its structural-institutional and functional aspects. The method of the research is literature review. Results and Discussion: According to the results of this research; Establishing an ombudsman for local governments in Turkey by law, cooperating with other ombudsmen in the vicinity, examining and correcting the mismanagement and bad behavior of local governments upon public demand, ensuring easy and cheap access, fulfilling their duties, and quickly and systematically addressing the faults of local governments. Warning, making suggestions, preparing reports and then reporting the situation to local decision-making boards and the public will be effective in providing public services more effectively and efficiently and strengthening local democracy. Originality/value: In the study, original suggestions are made for local government ombudsman in Turkey, based on the examples of UK and Italy.

This work aims to analyze the Caputo-Fabrizio fractional Newell-Whitehead-Segel (NWS) equation utilizing the Caputo-Fabrizio q-Elzaki homotopy analysis transform method. The Newell-Whitehead-Segel equation is a partial differential equation employed for modeling the dynamics of reaction-diffusion systems, specifically in the realm of pattern generation in biological and chemical systems. A convergence analysis of the proposed method was performed. Two-dimensional and three-dimensional graphs of the solutions have been drawn with the Maple software. It is seen that the resulting proposed method is more powerful and effective than the Aboodh transform homotopy perturbation method and conformable Laplace decomposition method in the results.
